[0002] With the development of technology, the traditional garment manufacturing industry is becoming increasingly intelligent, and automatic sewing equipment is gradually becoming more widespread and applied in the garment sewing process. However, the automation of existing individual sewing machines still requires manual labor to complete the corresponding sewing operations, which cannot meet the intelligent needs of daily production processes in factories. This not only wastes labor costs and production time but also reduces the overall production efficiency. Existing equipment can only perform sewing mechanically and cannot follow up with existing sewing information to provide operational prompts.

[0003] In conclusion, how to achieve intelligent manufacturing in the garment sewing process and improve sewing production efficiency are urgent problems that need to be solved. Summary of the Invention

[0004] The main purpose of this application is to overcome the shortcomings and deficiencies of the prior art and provide a control method for automatic sewing equipment. By intelligently confirming the current sewing information and providing corresponding operation prompts, the generation rate of defective products in the garment sewing process is reduced and the sewing production efficiency is improved.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a control method for an automatic sewing equipment, the sewing equipment including a feeding module, a piecing module, a sewing module, and a discharging module; the control method includes the following steps:

[0007] The sewing equipment receives sewing information and confirms the sewing trajectory and sewing style based on the sewing information;

[0008] Sewing inspection is performed based on the sewing style to obtain the sewing inspection results;

[0009] Based on the confirmed sewing trajectory, sewing style, and sewing inspection results, the pre-sewing inspection is completed;

[0010] The feeding module picks up the cut pieces and conveys them to the joining module. The joining module joins different cut pieces together to obtain a finished cut piece.

[0011] The sewing module sews the assembled cut pieces together to obtain a sewn garment;

[0012] The sewn garment is then transported to the unloading module for unloading.

[0013] As a preferred technical solution, the sewing information includes the method of joining the cut pieces and the template information of the cut pieces.

[0014] As a preferred technical solution, the sewing inspection includes the inspection of the sewing presser specifications and the inspection of the care label, specifically:

[0015] If the pressure plate specifications do not meet the requirements, the user will be prompted to replace the corresponding pressure plate.

[0016] If the washing label fails the test, the washing label will be replaced. If no washing label is detected, the user will be prompted to add a washing label.

[0017] Once the specifications of the pressure plate and the washing label have been checked and confirmed, the sewing work can begin.

[0018] As a preferred technical solution, the step of prompting the user to add a care label if no care label is detected is achieved by determining whether there is a corresponding care label in the care label sewing area. If no care label is placed, the user is prompted to add a care label and the corresponding sewing work is stopped.

[0019] The methods for determining whether there is a corresponding care label in the sewn area of ​​the care label include weighing and photoelectric sensing.

[0020] As a preferred technical solution, the method further includes calibrating the position of the cut piece; the position of the cut piece is calibrated by taking a picture of the cut piece with a cut piece gripper to obtain a cut piece image, and then locating the cut piece image to confirm the position information of the cut piece.

[0040] Furthermore, the sewing information includes the joining method of the cut pieces and the template information of the cut pieces; the template information of the cut pieces is obtained based on the sewing information. If the sewing equipment does not store the corresponding template information, the sewing equipment automatically switches to the template generation interface and generates the corresponding template according to the user's settings. The settings of the template include, but are not limited to, the size, shape, color, and comparison value of the front and back cut pieces.

[0041] S2. Perform sewing inspection based on the sewing style to obtain the sewing inspection results.

[0042] Furthermore, in this embodiment, the sewing inspection of the sewing equipment includes: inspection of the sewing presser plate specifications and inspection of the care label; if the presser plate specifications do not meet the requirements, the user is prompted to replace the corresponding presser plate; if the care label does not meet the requirements, the care label is replaced; if no care label is detected, the user is prompted to add a care label. Please refer to [link to relevant documentation]. Figure 3 .

[0043] If no care label is detected, the user is prompted to add a care label. The care label detection is achieved by determining whether there is a corresponding care label in the care label sewing area. If no care label is placed, the user is prompted to add a care label, and the corresponding sewing work is stopped. The methods for determining whether there is a corresponding care label in the care label sewing area include weighing and photoelectric sensing.

[0044] Specifically, the steps for adding and replacing care labels are as follows: the sewing equipment detects the position of the gripper adhesive unit in the care label assembly 5 and controls the gripper adhesive unit to move away from the stacking unit to complete the addition or replacement of different care labels;

[0045] Once the specifications of the pressure plate and the washing label have been checked and confirmed by the user, the sewing work can begin.

[0049] The cutting piece image is positioned to confirm the position information of the cutting piece. The steps are as follows: acquire the image information of the workbench and the image information of the cutting piece; confirm the outline information of the cutting piece based on the image information of the cutting piece; confirm the position information of the cutting piece based on the ratio of the outline information of the cutting piece to the workbench; confirm the outline edge information of the cutting piece; adjust the joining area of ​​the cutting piece based on the outline edge information of the cutting piece; and further adjust the displacement position of the cutting piece gripper.

[0050] In this embodiment, the control method for the automatic sewing equipment further includes the status detection of the sewing equipment. Please refer to [link to relevant documentation]. Figure 4 , Figure 5 Its status detection includes sewing action detection in standby mode and sewing action detection in restart mode;

[0051] (1) Sewing action detection in standby mode: When the sewing equipment receives sewing information, it first determines whether the current sewing information has changed. If it has changed, it confirms the corresponding cut piece template information, including whether the system stores cut piece template information. If the system stores the corresponding cut piece template information, the automatic sewing equipment detects the quality of the cut piece to be sewn based on the cut piece template information. If the system does not store the corresponding cut piece template information, it prompts the user to set the corresponding cut piece template. The system receives the newly set cut piece template information from the user and detects the quality of the cut piece to be sewn based on the newly set cut piece template information. Next, it determines the corresponding presser information based on the sewing information, including prompting the user to replace the presser if adjustment is required, and not prompting if no adjustment is required. Finally, it determines the care label information corresponding to the sewing information, including prompting the user to replace the care label if adjustment is required, and not prompting if no adjustment is required. If the sewing equipment receives the sewing information and determines that the sewing information has not changed, it determines whether there is cut piece template information in the joining area and whether there is a corresponding care label in the care label area. After completing the detection, it performs sewing.

[0052] The sewing action in standby mode also includes pre-processing, where users can set corresponding sewing information through the control panel. This sewing information includes sewing trajectory, pattern information, presser plate information, and care label information.

[0053] (2) Sewing action detection in restart state: Receive user instruction information, for example: the user is "reset", the device confirms its own operation information based on the instruction information, that is, the position information of each module is reset and confirmed; the sewing device receives sewing information and confirms the status of the corresponding module according to the sewing information; the confirmation of the status of the corresponding module according to the sewing information includes reconfirming whether the piece assembly module has the corresponding cut piece, the corresponding pressure plate information and the washing label information, and after confirmation, sewing is performed according to the confirmation information fed back by the user.

[0054] S4. The feeding module picks up the cut pieces and conveys them to the piece-assembly module. The piece-assembly module combines different cut pieces to obtain a piece of cut pieces that has been assembled.

[0055] Specifically, the joining module includes a first joining unit and a second joining unit; the first joining unit and the second joining unit are used for different cut pieces; the feeding module respectively transports different cut pieces to the first joining unit and the second joining unit, confirms the corresponding joining method and sewing position based on the acquired sewing information, and joins the different cut pieces according to the joining method and sewing position.

[0056] In this embodiment, after obtaining the assembled cut pieces, a conveying component is also included to press the assembled cut pieces together and to convey the pressed assembled cut pieces to the sewing module.

[0057] S5. The sewing module sews the assembled cut pieces to obtain a sewn garment.

If a cut piece is unqualified, it is transferred to the recycling area, and the piece gripping unit moves to obtain a new cut piece for piecing. If the piece gripping unit detects that there is no corresponding cut piece, the device stops sewing and prompts the user to add the corresponding cut piece (i.e., replenishment operation). If the piece gripping unit detects that there is no corresponding cut piece, and the user confirms adding the corresponding cut piece, the piece placement unit of the feeding module descends, the gripping unit moves away from the piece placement unit, places the cut piece in the placement unit, and the sewing device resumes operation.

[0059] In addition, if an error is detected in the sewing process in this embodiment, the user can force shutdown to stop the sewing operation. When the user selects to reset, the device will re-perform the detection and sewing preparation work to avoid sewing errors.

[0060] S6. The sewn garment is transported to the unloading module for unloading.

[0061] Furthermore, the feeding module detects the information of the sewn cut pieces. If the information of the sewn garment stored in the feeding area reaches the warning area, the user is prompted to move the sewn garment. The method of detecting that the information of the sewn garment has reached the warning area can also be a photoelectric switch or weight detection.

[0062] The sewing device in this embodiment also includes an emergency stop button and an auxiliary switching button as physical control buttons;

[0063] The emergency stop button is used to control the equipment to stop operating in an emergency. There are multiple emergency stop buttons so that users can easily find the nearest one in an emergency. By setting multiple physical buttons for forced shutdown on the sewing equipment, users can easily shut down the equipment in a timely manner. The equipment has a large volume.

[0064] The auxiliary switching buttons include a material replenishment platform button, a pressure plate switching button, a washing label switching button, and a material unloading platform button;

[0065] When the sewing equipment is in the "stop" state, the corresponding module will respond when the user touches the corresponding auxiliary switch button; when the sewing equipment is running, the auxiliary switch button will not respond when the user touches it.

[0066] Specifically:

[0067] The replenishment platform button: When the user touches the replenishment platform button, the piece placement unit of the feeding module descends, and the gripping unit moves away from the piece placement unit (to facilitate the user placing the piece). After placing the piece in the placement unit, the user selects the reset button, and the sewing equipment resumes operation.

[0068] The pressure plate switching button: Different sizes of cut pieces require different pressure plates during the sewing process. When the sewing equipment prompts the user to change the pressure plate, the user touches the corresponding pressure plate switching button, and the pressure plate assembly moves away from the sewing module's table and rotates to facilitate the user's pressure plate replacement.

[0069] The care label switching button: When the user touches the care label switching button, the sewing equipment detects the position of the gripper sticking unit of the care label assembly and controls the gripper sticking unit to move away from the stacking unit to replace different care labels.

[0070] In addition, the sewing equipment of this application also includes a control panel, an interface for interacting with the user.

[0071] In summary, in this application, the automatic sewing equipment automatically detects the corresponding pressure plate information and care label information based on the sewing information selected by the user, and marks the position of the cut pieces.
