[0002] A zipper is a connector used to join or separate items. It mainly consists of teeth, a slider, a top stop, and a bottom stop fixed to a fabric tape. Due to its ease of use, it is widely used in clothing, bags, and other daily necessities. After zipper production is completed, quality inspection is required. Inspection methods include traditional manual inspection and machine vision inspection.

[0003] However, traditional manual inspection of zippers inevitably causes eye fatigue, reducing the accuracy of zipper quality checks. While existing machine vision inspection can avoid the problem of human fatigue reducing inspection quality when performing online defect detection on zippers, it suffers from inconvenience in sorting or the need to pause the process for rejection, making it difficult to ensure a smooth zipper inspection flow and affecting the overall efficiency of production inspection. Therefore, we need to propose an online zipper quality inspection and defect rejection device. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides: an online zipper quality inspection and defect rejection device, including a mounting frame 1, a conveyor belt 2, a support bracket 3 mounted on the top of the mounting frame 1, and a fixing frame 14; the surface of the support bracket 3 is movably connected to an assembly frame 4 via a lifting module 6, and the surface of the assembly frame 4 is detachably mounted with an online inspection camera 8 via a positioning component; an adjusting screw 16 is installed inside the fixing frame 14, and an adjusting connecting rod 22 is movably connected to the surface of the adjusting screw 16, with an adjusting limit plate 23 connected to the other end of the adjusting connecting rod 22; a locking component for fixing the adjusting screw 16 is installed on the surface of the fixing frame 14; a rejection nozzle 13 for rejecting defective zippers is installed on one side of the support bracket 3 at the top of the mounting frame 1, and a diversion plate 12 for classifying zippers is provided diagonally opposite the rejection nozzle 13.

[0021] It is worth noting that, through the coordinated arrangement of structures such as mounting frame 1, bearing bracket 3, fixing frame 14, adjusting limit plate 23, positioning component and locking component, unqualified zippers can be promptly removed during online zipper inspection. Furthermore, the removed unqualified zippers can be sorted and unloaded without stopping the machine, further ensuring the smoothness of the zipper inspection process and effectively improving the efficiency of zipper inspection.

[0022] The positioning assembly includes a fixed frame 9 mounted on the surface of the assembly frame 4, and positioning blocks 10 connected to both sides of the fixed frame 9. The surface of the assembly frame 4 has an assembly slot 7, and the surface of the positioning blocks 10 is slidably inserted into the inner wall of the assembly slot 7. The surface of the fixed frame 9 is equipped with a locking member 11 connected to the assembly frame 4. Limiting connecting blocks 5 are connected to both ends of the assembly frame 4, and the limiting connecting blocks 5 are movably connected to the lifting end of the lifting module 6.

[0023] Furthermore, by driving the limit connecting block 5 through the lifting module 6 to control the up-and-down movement of the assembly frame 4, the height of the online inspection camera 8 can be precisely adjusted to adapt to zipper products of different thicknesses or stacking heights, ensuring optimal imaging results. The structure of the positioning component—fixed frame 9, positioning insert 10, assembly slot 7, and locking element 11—allows for quick disassembly and replacement of the online inspection camera 8 on the surface of the assembly frame 4. This facilitates maintenance, cleaning, or upgrades of the online inspection camera 8.

[0024] One end of the adjusting rod 22 is movably connected to a movable plate 21, which is movably mounted on the surface of the adjusting screw 16. The inner surface of the adjusting limit plate 23 is connected to a connecting shaft 24, and the other end of the adjusting rod 22 is movably connected to the surface of the connecting shaft 24.

[0025] Specifically, the transmission mechanism consisting of the adjusting screw 16, the moving plate 21, the adjusting connecting rod 22, and the connecting shaft 24 can easily and accurately adjust the position of the adjusting limit plate 23, enabling the equipment to easily adapt to zipper products of different widths, ensuring that the zipper remains stable during inspection and conveying, avoiding deviation, and improving the inspection accuracy of the online inspection camera 8.

[0026] The rejection nozzle 13 is connected to an external air source pump via a pipeline. The rejection nozzle 13, which is set on one side of the support bracket 3, can quickly respond to the detection results of the online detection camera 8. When the online detection camera 8 detects a defective product, it sends a signal to the computer to start the air pump and use high-pressure gas to accurately blow the defective zipper to the other side of the conveyor belt 2. In conjunction with the diverter plate 12 set diagonally opposite the rejection nozzle 13, the blown-out defective products can be effectively guided to a specific collection area to achieve physical separation from qualified products, avoid mixing, and improve sorting efficiency.

[0027] The locking assembly includes: a mounting base 15 connected to the surface of the fixing frame 14, and a gear 17 mounted on the surface of the adjusting screw 16; wherein, an adjusting rod 20 is slidably connected inside the mounting base 15, and an arc-shaped positioning toothed plate 18 is rotatably connected to the bottom end of the adjusting rod 20, and the two sides of the arc-shaped positioning toothed plate 18 are slidably connected to the inner wall of the mounting base 15. A compression spring 19 is fitted on the surface of the adjusting rod 20, the top end of the compression spring 19 is connected to the top of the inner wall of the mounting base 15, and the bottom of the arc-shaped positioning toothed plate 18 is engaged with the surface of the gear 17.

[0028] Furthermore, the locking assembly's mounting base 15, adjusting rod 20, compression spring 19, arc-shaped positioning toothed plate 18, and gear 17 mounted on the adjusting screw 16 work together to further improve the reliable screw locking effect. Lifting the adjusting rod 20 causes the compression spring 19 to contract, disengaging the arc-shaped positioning toothed plate 18 from the gear 17, allowing the adjusting screw 16 to be easily rotated for adjustment. After releasing the adjusting rod 20, the compression spring 19 returns to its original position, pushing the arc-shaped positioning toothed plate 18 to tightly mesh with the gear 17, firmly locking the adjusting screw 16. This prevents unexpected changes in the limit position due to vibration during equipment operation, effectively controlling the position of different zipper conveyors and ensuring the stability and consistency of detection and rejection.

[0029] In use, according to the width of the zipper, the arc-shaped positioning toothed plate 18 is lifted by adjusting rod 20 to release the locking of adjusting screw 16. The adjusting screw 16 can be rotated to control the position of adjusting limit plate 23 connected to adjusting linkage 22, ensuring the stability of zipper conveying by conveyor belt 2. After completion, the adjusting rod 20 is released, and the compression spring 19 acts on the arc-shaped positioning toothed plate 18, which meshes with gear 17 to fix it, improving the stability of the limiting position of adjusting limit plate 23. As needed, the position of online detection camera 8 can be adjusted by lifting module 6 to facilitate online monitoring of zippers by online detection camera 8. When a defective product is detected, the rejection nozzle 13 uses high-pressure gas to accurately blow the defective zipper to the other side of conveyor belt 2. With the help of diverter plate 12, the defective product can be effectively guided to a specific collection area to achieve physical separation from qualified products and avoid mixing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
