Description

Technical Field

[0001] This utility model relates to the field of zipper production and testing equipment, and more specifically to an integrated machine for testing the cutting of closed-end zippers. Background Technology

[0002] After the zipper tape is produced, the zipper teeth need to be inspected to check for missing teeth and whether the shape of the teeth is up to standard.

[0003] Currently, most automated inspection methods use cameras for image capture. For example, the utility model patent filed by the applicant on June 24, 2025, with publication number CN223021971U, uses a camera assembly to detect defects in zippers. However, in this device, a length measuring component is formed by combining a measuring guide wheel and a measuring encoder. This component measures the length of the zipper tape and controls the final cutting of the zipper tape. However, the structure of this device cannot control the size of the zipper tape during the camera inspection process. Furthermore, the inspection of an entire zipper tape needs to start from the bottom. Therefore, when inspecting zipper tapes of different lengths, this device is prone to missing some samples. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated machine for detecting and cutting closed-end zippers. By setting a size positioning device on the frame, it can accurately position zipper tapes of different lengths and specifications, thus avoiding omissions in the detection.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a closed-end zipper cutting and inspection integrated machine, including a frame and a zipper feeding device, a camera detection device and an ultrasonic cutting and discharge device installed on the frame. A size positioning device is provided on the frame below the camera detection device. The zipper tape is pulled out from the zipper feeding device, passes through the camera detection device and then through the size positioning device, and finally enters the ultrasonic cutting and discharge device.

[0006] As a further improvement of this utility model, the size positioning device includes a size positioning horizontal plate and a size positioning wheel. The size positioning horizontal plate is horizontally installed below the camera detection device. The size positioning wheel is movably mounted on the size positioning horizontal plate. One end of the size positioning horizontal plate is provided with a discharge wheel. The zipper belt passes around the size positioning wheel and the discharge wheel in sequence, so as to achieve size positioning adjustment of the zipper belt by changing the distance between the moving size positioning wheel and the discharge wheel.

[0007] As a further improvement of this utility model, a size positioning motor is fixed to one end of the size positioning horizontal plate. A lead screw is coaxially fixed to the shaft of the size positioning motor. The length direction of the lead screw is the same as the length direction of the size positioning horizontal plate. A size positioning seat is provided on the size positioning horizontal plate that can be slidably. A size positioning wheel is rotatably mounted on the size positioning seat. The size positioning seat and the lead screw are threadedly connected.

[0008] As a further improvement of this utility model, the camera detection device includes a detection box and a positioning component disposed above the detection box. The detection box has interconnected chain holes on its upper and lower sides. The zipper belt passes through the positioning component, enters the detection box through the upper chain hole for detection, and after the detection is completed, extends out through the lower chain hole and enters the size positioning device.

[0009] As a further improvement of this utility model, the positioning assembly includes a positioning bracket, a front sprocket, a rear sprocket, a positioning base, a positioning cylinder, and a positioning guide wheel. The positioning bracket is mounted on the frame, the positioning base is fixedly mounted on the positioning bracket and positioned above the detection box, the positioning cylinder is fixedly mounted above the positioning base and has a push rod set downwards, on which a positioning pressure block is fixed. The positioning guide wheel is rotatably positioned above the positioning base, and the zipper belt passes through the top of the positioning base and the bottom of the positioning pressure block and the positioning guide wheel.

[0010] The beneficial effects of this utility model are that, by setting up a size positioning device, it can accurately position zipper tapes of different lengths, ensuring that the inspection starts from the bottom and avoiding inspection omissions. It integrates the zipper feeding, inspection, positioning, and cutting and unloading into one unit, improving inspection efficiency. Subsequently, the size positioning wheel position is adjusted by a motor-driven screw, realizing automated and precise adjustment. The positioning component ensures that the zipper tape passes stably through the inspection box, improving inspection accuracy. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0016] Reference Figure 1 As shown, the integrated zipper cutting and inspection machine of this embodiment includes a frame 1 and a zipper feeding device 2, a camera inspection device 3, and an ultrasonic cutting and discharge device 4 mounted on the frame 1. A size positioning device 5 is located below the camera inspection device 3 on the frame 1. The zipper tape is pulled out from the feeding device 2, passes through the camera inspection device 3, then through the size positioning device 5, and finally enters the ultrasonic cutting and discharge device 4. The zipper tape enters the equipment from the feeding device 2 and sequentially passes through the AI ​​intelligent vision system mounted on the camera inspection device 3 to complete defect detection such as missing zipper teeth and shape defects. This system has a fast modeling speed, can quickly adapt to the inspection needs of different zipper specifications, and has AI self-learning capabilities to continuously optimize the accuracy of the inspection model. Then, precise positioning is achieved through the size positioning device 5, and finally, the ultrasonic cutting and discharge device 4 completes the cutting and discharge. This solution ensures that inspection starts from the bottom edge through the size positioning device 5, solving the problem of omissions, and integrates the feeding, inspection, positioning, and cutting / discharging processes into a single process, improving inspection efficiency.

[0017] Reference Figure 2 As shown, the size positioning device 5 further includes a size positioning horizontal plate 51 and a size positioning wheel 52. The size positioning horizontal plate 51 is horizontally installed below the camera detection device 3. The size positioning wheel 52 is movably mounted on the size positioning horizontal plate 51. One end of the size positioning horizontal plate 51 is provided with a discharge wheel 54. The zipper tape passes around the size positioning wheel 52 and the discharge wheel 54 in sequence. By changing the distance between the moving size positioning wheel 52 and the discharge wheel 54, the size positioning of the zipper tape is adjusted, providing a stable positioning basis for AI intelligent visual inspection and adapting to inspection scenarios of different specifications of zipper tape. This structure assists in achieving accurate positioning, flexibly adapts to various zipper tape specifications, and improves the versatility of the equipment.

[0018] Furthermore, a size positioning motor is fixed to one end of the size positioning horizontal plate 51. A lead screw is coaxially fixed to the shaft of the size positioning motor, and the length direction of the lead screw is the same as the length direction of the size positioning horizontal plate 51. A size positioning seat 55 is movably mounted on the size positioning horizontal plate 51, and a size positioning wheel 52 is rotatably mounted on the size positioning seat 55. The size positioning seat 55 is threadedly connected to the lead screw. The motor drives the lead screw to adjust the position of the size positioning wheel 52, achieving automated and precise adjustment. This provides reliable size positioning support for the stable operation of AI intelligent visual inspection, improves adjustment accuracy and efficiency, and reduces manual intervention.

[0019] Furthermore, the camera detection device 3 includes a detection box 31 and a positioning component 32 disposed above the detection box 31. The detection box 31 has interconnected zipper holes on its upper and lower sides. The zipper tape passes through the positioning component 32, enters the detection box 31 through the upper zipper hole for detection, and after detection, extends out through the lower zipper hole and enters the size positioning device 5. The zipper tape is stably entered into the detection box 31 via the positioning component 32. Figure 4 As shown, the inspection box 31 is equipped with two opposing inspection cameras. The AI ​​intelligent vision system installed in the inspection cameras completes high-precision defect detection. This system has a fast modeling speed, can quickly adapt to the inspection needs of different zipper specifications, and has AI self-learning capabilities, which can continuously optimize the accuracy of the inspection model. This structure ensures accurate positioning during inspection and improves the stability and accuracy of AI inspection.

[0020] Reference Figure 3 As shown, the positioning component 32 further includes a positioning bracket 321, a front sprocket 322, a rear sprocket 323, a positioning base 324, a positioning cylinder 325, and a positioning guide wheel 326. The positioning bracket 321 is mounted on the frame 1. The positioning base 324 is fixedly mounted on the positioning bracket 321 and positioned above the inspection box 31. The positioning cylinder 325 is fixedly mounted above the positioning base 324 and has a downward-pointing push rod with a positioning pressure block fixed on it. The positioning guide wheel 326 is rotatably positioned above the positioning base 324. The zipper belt passes above the positioning base 324 and below the positioning pressure block and the positioning guide wheel 326. The positioning cylinder 325 pushes the pressure block to cooperate with the positioning guide wheel 326 to fix the zipper belt. The front sprocket 322 and the rear sprocket 323 guide the zipper belt, providing a stable inspection environment for AI intelligent visual inspection, ensuring that the fast-modeling and self-learning AI system can perform optimally, and enhancing positioning reliability and inspection accuracy.
