The CNC VINA Automatic Jig Opening Sewing Machine No.2 is an automated sewing solution designed to perform sewing operations according to pre-programmed patterns using a two-axis X/Y motion system. The machine integrates a JUKI industrial sewing machine with a dedicated positioning jig, precision motion mechanism, and PLC-based control system to automate product positioning, clamping, sewing, thread trimming, return-to-home operation, and automatic jig opening upon completion of the sewing cycle. The Automatic Jig Opening Sewing Machine No.2 is suitable for products requiring consistent control of sewing position and seam profile throughout the production process. Products are accurately positioned using a dedicated jig before the machine executes the programmed sewing pattern, helping reduce dependence on manual operations and maintain consistent results across products of the same model.

The XY programmable sewing machine can be configured and customized according to product characteristics, dimensions, sewing positions, positioning and clamping requirements, and the specific production process of each customer.

Overview of the CNC VINA Automatic jig opening sewing machine no.2

The CNC VINA Automatic Jig Opening Sewing Machine No.2 is developed based on an XY programmable sewing machine configuration, integrating an industrial sewing machine with an automated two-axis X/Y motion system. Before each sewing cycle, the workpiece is accurately positioned on the jig. Once the Start signal is activated, the jig automatically clamps the workpiece, while the control system initiates the corresponding sewing program. During operation, the X/Y motion mechanism follows the programmed trajectory to create the required sewing pattern. Upon completion, the machine automatically trims the thread, returns to the home position, and opens the jig, allowing the operator to remove the finished workpiece.

One of the key features of the Automatic Jig Opening Sewing Machine No.2 is its warning function when the operator presses Start while the jig has not been properly closed. This function helps verify the jig status before the sewing cycle begins and prevents operation when the workpiece has not been securely clamped.

For production involving multiple product models, the operator can select the corresponding sewing program on the control panel and replace the jig according to the configuration of each product.

Operating principle of the automatic sewing machine

The XY programmable sewing machine operates through the coordinated movement of the industrial sewing machine, jig assembly, and two-axis X/Y motion system. The motion trajectory is defined in the control program, allowing the machine to perform sewing operations according to the specified position and seam profile. After the workpiece is positioned on the jig, the operator presses Start. The jig automatically clamps the workpiece in place. Once the required operating conditions are confirmed, the Delta Servo system controls the motion mechanism according to the programmed sequence, coordinating X/Y movements throughout the sewing process. After the sewing operation is completed, the machine automatically trims the thread, returns the motion mechanism to the home position, and opens the jig. The operator then removes the finished workpiece and loads the next one.

Structure of the CNC VINA Automatic jig opening sewing machine No.2

Machine frame assembly

The machine frame consists of upper and lower structural assemblies that support the sewing machine, jig assembly, motion mechanism, and other related components. The overall structure is designed to meet the required operating height and installation conditions within the production area.

JUKI industrial sewing machine

The machine is equipped with a JUKI industrial sewing machine as the primary sewing unit. The sewing machine is integrated with the automated motion system, enabling it to perform sewing operations along trajectories controlled by the XY program.

Positioning and clamping jig assembly

The jig is responsible for accurately positioning, clamping, and securing the workpiece during the sewing process. Depending on the product geometry and production requirements, the jig can be designed with positioning pins, clamping mechanisms, and contact surfaces tailored to the specific workpiece. During the operating cycle, the jig automatically clamps down after the operator presses Start. Once the sewing operation is completed, the jig automatically opens to allow the operator to remove the finished product.

For different product models, dedicated jigs can be designed and replaced accordingly, with each jig configuration combined with its corresponding sewing program in the control system.

Two-Axis X/Y motion assembly

The X/Y motion assembly uses ball screws and high-precision linear guide rails, with component options including TBI, PMI, and HIWIN, or equivalent configurations depending on the application requirements. The Delta Servo and Encoder system controls the positioning and movement of the mechanism according to the programmed sequence. The X and Y axes operate in coordination to generate the required sewing trajectory and seam profile.

PLC control system

The machine control system consists of a PLC integrated with a Delta HMI control panel. The operator interface allows users to select sewing programs, operate the machine, and monitor equipment status during production. The PLC also coordinates and synchronizes the operation of the jig, motion system, sewing machine, and related control signals throughout each stage of the operating cycle.

Protective cover assembly

The protective cover is installed around the machine's operating area to protect internal mechanisms from external factors in the production environment while providing a suitable operating area for the machine.

Technical specifications may be customized according to the equipment configuration, product characteristics, and specific requirements of each project.

Key features of the automatic jig opening sewing machine No.2

Automatic Sewing Based on XY Programmable Patterns

The Automatic Jig Opening Sewing Machine No.2 performs sewing operations according to programs configured in the machine control system. The two-axis X/Y motion mechanism works in coordination to generate the required sewing trajectory based on the specified position and seam profile.

Program-controlled operation reduces reliance on manual guiding and positioning by the operator for each individual workpiece, helping maintain consistent sewing operations throughout the production process.

Automatic jig clamping and opening

The jig automatically clamps the workpiece at the beginning of each cycle and opens automatically once the sewing operation is completed. The operator does not need to manually open or close the jig during each production cycle.

Warning when the jig is not closed

The machine is equipped with a warning function that is activated when the operator presses Start while the jig is not closed. This function verifies the jig status before the cycle begins, helping prevent machine operation when the workpiece has not been properly secured.

Automatic thread trimming and return to home position

After completing the programmed sewing pattern, the machine automatically trims the thread and returns the motion mechanism to the home position. The jig then opens automatically, allowing the operator to remove the finished workpiece from the machine.

Flexible model changeover with programs and jigs

When producing multiple product models, the operator can select the corresponding sewing program and replace the jig according to the product configuration. This setup allows the XY programmable sewing machine to accommodate multiple product variants rather than being dedicated to a single model.

Applications of the CNC VINA Automatic Sewing Machine

The CNC VINA Automatic Jig Opening Sewing Machine No.2 is designed for production processes that require automated workpiece positioning, clamping, and sewing along a predefined pattern or profile.

Instead of manually aligning the workpiece, holding the material, and controlling the sewing operation during each cycle, the machine performs the programmed sequence automatically: loading the workpiece onto the jig, clamping it securely, moving along the programmed X/Y trajectory, completing the sewing operation, trimming the thread, returning to the home position, and opening the jig for workpiece removal.

The equipment is well suited for manufacturers with high-volume production requirements, consistent sewing quality targets, and a need to reduce dependence on individual operator skill. Once the workpiece is correctly positioned on the jig, the sewing position is controlled according to the programmed pattern, helping minimize issues such as seam deviation, incorrect positioning, inconsistent sewing, and excessive rework after completion.

Applications in High-Volume Production

In high-volume production lines, the CNC VINA Automatic Sewing Machine helps standardize operating procedures across different production shifts. The operator mainly needs to load the workpiece onto the jig, select the appropriate program, and press Start. The remaining operations are automatically performed according to the predefined cycle. This operating method allows manufacturers to better control cycle time, production output, and product quality. When operators or production shifts change, the standardized machine sequence helps maintain consistent operation without relying heavily on individual experience or sewing skills.

Solution for Products Requiring High-Precision Sewing

The equipment is suitable for products with fixed sewing positions, predefined seam profiles, corner patterns, rectangular patterns, curved seams, or other sewing trajectories that require program-based control. The two-axis X/Y motion system enables the machine to follow programmed coordinates while working in synchronization with the industrial sewing machine to produce the required seam pattern.

For products where even minor sewing deviations can affect assembly, appearance, or finished-product quality, combining a dedicated positioning jig with programmable automatic sewing helps reduce positioning errors and production risks.

Applications for multiple product models

The Automatic Jig Opening Sewing Machine No.2 can be configured to accommodate multiple jigs and sewing programs. When changing to a different product model, the operator can replace the corresponding jig and select the appropriate program from the control panel. This solution is suitable for manufacturers producing multiple product variants, products with different dimensions, or orders that require frequent model changeovers. Instead of investing in a dedicated machine for each product, manufacturers can use a single machine system with interchangeable jigs and corresponding sewing programs, helping optimize floor space and investment costs.

Applications for processes requiring reduced manual operations

In conventional manual sewing processes, operators may need to perform multiple consecutive tasks, including product alignment, material positioning, sewing operation, thread trimming, and product removal. Repetitive manual operations over extended periods can increase operator fatigue, reduce productivity, and increase the risk of errors caused by loss of concentration.

With the CNC VINA Automatic Sewing Machine, repetitive operations are automated. The jig handles product positioning and clamping, the X/Y motion system controls the programmed sewing trajectory, and the machine automatically trims the thread and opens the jig after completing the cycle. This allows operators to focus primarily on workpiece loading, product inspection, and other tasks within the production area.

Applications in automated production lines

The machine can be operated as a standalone production station or integrated into an automated production line depending on the customer's requirements. Where integration with other equipment is required, CNC VINA can evaluate solutions incorporating automatic loading and unloading mechanisms, conveyors, sensors, or communication signals between machines. Depending on the factory layout and existing production process, the equipment can be configured for manual loading, semi-automatic operation, or integration with upstream and downstream processes. This enables manufacturers to progressively automate their production lines without necessarily replacing the entire existing production system.

Application-based customization for different products

Each product may differ in dimensions, material, thickness, sewing position, and fixturing requirements. Therefore, the Automatic Jig Opening Sewing Machine No.2 is not limited to a single fixed configuration. CNC VINA evaluates the product sample, drawings, sewing positions, target cycle time, and required production output to develop an appropriate solution. The jig can be custom-designed according to the product profile and equipped with positioning pins, clamping mechanisms, or other supporting components to minimize workpiece movement during sewing. The motion program is also developed based on the actual sewing pattern, helping ensure stable machine operation and compatibility with the customer's specific production requirements.

Maintenance of the Automatic Sewing Machine

To maintain stable machine performance, the Automatic Jig Opening Sewing Machine No.2 should be cleaned after each production shift, while the mechanical mechanisms, electrical system, and pneumatic system should be inspected before operation. Before carrying out maintenance or inspection, the machine must be returned to the home position, and all electrical and pneumatic power sources must be disconnected before work begins. The motion mechanisms, jig assembly, sewing machine, and control components should be inspected and maintained according to the recommended maintenance schedule.

Following proper maintenance procedures helps minimize operational issues and maintain equipment stability throughout its service life.

Practical Benefits for Manufacturers

Implementing the CNC VINA Automatic Sewing Machine in production can provide several practical benefits:

• Reduce manual handling time during each production cycle.
• Maintain more consistent sewing positions and seam profiles.
• Minimize errors caused by inaccurate product positioning.
• Reduce dependence on individual operator skill.
• Improve control over cycle time and production output.
• Enable model changeover by replacing the jig and selecting the corresponding program.
