Abstract
Description
Zipper tape inspection machine Technical Field
[0001] This utility model relates to a testing device, and more specifically to a zipper tape testing machine. 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 existing chain tooth detection technologies use a single detection device. For example, the utility model patent CN221631712U, entitled "A Chain Tooth Detection Device," discloses a method of detecting missing teeth by setting up a detection component. During detection, the component detects missing teeth by observing the movement of a movable part. However, this method can only detect missing teeth. When the chain tooth shape is unqualified, the movement of the movable part alone cannot effectively detect it. Therefore, existing detection devices cannot detect defects other than missing teeth, and their functionality is insufficient. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a zipper tape inspection machine that can detect defects other than missing zipper teeth.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper tape inspection machine, comprising a zipper guide device, a front zipper tape device, an inspection device, and a rear zipper tape device. The zipper tape is fed into the machine from the zipper guide device and passes through the front zipper tape device, the inspection device, and the rear zipper tape device. The inspection device includes an inspection bracket, a camera assembly, and several guide wheels. The guide wheels are rotatably mounted on the inspection bracket to guide the zipper tape through the camera area of the camera assembly.
[0006] As a further improvement of this utility model, the detection bracket includes a fixed base plate and a fixed upright plate. The fixed upright plate is vertically fixedly installed on the fixed base plate, and a plurality of guide wheels are installed on the fixed upright plate at intervals. The camera assembly is installed on the fixed base plate, such that the camera area of the camera assembly is located between the upper and lower guide wheels.
[0007] As a further improvement of this utility model, at least two detection brackets are provided, and at least three camera assemblies are provided. The two detection brackets are distributed vertically, and the two camera assemblies distributed horizontally form a group with a central imaging area. The two camera assemblies distributed horizontally and horizontally form a group with a light shield forming a central imaging area. The two camera assemblies are installed on the upper detection bracket, and the one camera assembly and the light shield are installed on the lower detection bracket.
[0008] As a further improvement of this utility model, the detection device also includes a pull tab flipping assembly, through which the zipper tape passes and flips the pull tab on the zipper tape.
[0009] As a further improvement of this utility model, the pull tab flipping assembly includes a chain guide plate, a chain guide upright plate, and a flipping plate. The chain guide plate is fixedly installed on the detection bracket, the chain guide upright plate is fixed on the left side of the chain guide plate, and the flipping plate is flexibly and selectively installed on the chain guide upright plate. The end of the flipping plate and the left side of the chain guide plate form a channel for the zipper belt to pass through. When the zipper belt passes through the channel, the flipping plate abuts against the pull tab on the zipper head, thereby driving the pull tab to flip.
[0010] The beneficial effects of this invention are as follows: Compared with existing technologies, which mostly use a single detection device that can only detect missing teeth and cannot effectively detect other defects such as unqualified zipper tooth shape, this invention, by setting up multiple detection brackets and camera components and rationally arranging them to form different camera areas, can more comprehensively detect zipper teeth. It can detect not only missing teeth but also various defects such as tooth shape, greatly improving the functionality and accuracy of the detection. Simultaneously, the zipper pull flipping component allows the zipper pull to be flipped, thereby detecting the part covered by the pull pull, further improving the detection function and overcoming the shortcomings of existing technologies. Attached Figure Description
[0011] Figure 1 is an overall structural diagram of the zipper tape testing machine of this utility model;
[0012] Figure 2 is a structural diagram of the detection device in Figure 1;
[0013] Figure 3 is a structural diagram of the pull tab flipping assembly in Figure 1. Detailed Implementation
[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.
[0015] Referring to Figure 1, the zipper tape inspection machine of this embodiment includes a zipper guide device 1, a front zipper tape device 2, an inspection device 3, and a rear zipper tape device 4. The zipper tape is fed from the zipper guide device 1 and passes sequentially through the front zipper tape device 2, the inspection device 3, and the rear zipper tape device 4. The inspection device 3 includes an inspection bracket 31, a camera assembly 32, and several guide wheels 33. The several guide wheels 33 are rotatably mounted on the inspection bracket 31, guiding the zipper tape through the imaging area of the camera assembly 32. This allows for a more comprehensive inspection of the zipper tape using the camera assembly 32, solving the problem of insufficient inspection functionality in the prior art. It can detect missing zipper teeth and whether the shape of the zipper teeth is qualified. In this embodiment, the camera assembly 32 is composed of a camera and a supplementary light.
[0016] Furthermore, referring to Figure 2, the detection bracket 31 includes a fixed base plate 311 and a fixed upright plate 312. The fixed upright plate 312 is vertically fixedly mounted on the fixed base plate 311, and several guide wheels 33 are spaced apart on the fixed upright plate 312. The camera assembly 32 is mounted on the fixed base plate 311, so that the imaging area of the camera assembly 32 is located between the upper and lower guide wheels 33. This structure can stably guide the zipper tape through the imaging area, improve detection accuracy, and avoid detection errors caused by unstable zipper tape position, making it more reliable than the background technology detection.
[0017] Furthermore, at least two detection brackets 31 and at least three camera assemblies 32 are provided. The two detection brackets 31 are arranged vertically, and the two horizontally distributed camera assemblies 32 form a central imaging area. Another pair of horizontally distributed camera assemblies 32 and a light shield also form a central imaging area. The two camera assemblies 32 are mounted on the upper detection bracket 31, and the one camera assembly 32 and the light shield are mounted on the lower detection bracket 31. By using multiple camera assemblies 32 and light shields in conjunction with multi-angle detection, zipper tape defects can be detected more comprehensively, overcoming the shortcomings of the single detection method in the prior art, which cannot comprehensively detect defects such as the shape of the zipper teeth. Moreover, the vertical distribution allows for better guidance of the zipper tape through the imaging area via the guide rollers 33.
[0018] Furthermore, referring to Figures 1 and 3, the detection device 3 also includes a pull tab flipping assembly 34. The zipper tape passes through the pull tab flipping assembly 34, which flips the pull tab on the zipper tape, exposing the area previously covered by the pull tab. The camera assembly 32 can then effectively take pictures for detection, ensuring that related zipper tape defects near the pull tab can be detected.
[0019] Furthermore, the pull tab flipping assembly 34 includes a chain guide plate 341, a chain guide upright plate 342, and a flipping plate 343. The chain guide plate 341 is fixedly mounted on the detection bracket 31, the chain guide upright plate 342 is fixed to the left side of the chain guide plate 341, and the flipping plate 343 is elastically and selectively mounted on the chain guide upright plate 342. The end of the flipping plate 343 and the left side of the chain guide plate 341 form a channel for the zipper tape to pass through. When the zipper tape passes through the channel, the flipping plate 343 abuts against the pull tab on the zipper head, thereby driving the pull tab to flip. This structure is simple and effective in achieving pull tab flipping, and it is simple and easy to implement. In this embodiment, a tension spring is connected to the end of the flipping plate 343 to achieve the elastic hinge of the flipping plate 343.
[0020] In summary, this zipper tape inspection machine, by setting up multiple inspection brackets 31, camera components 32, and pull tab flipping components 34, can comprehensively inspect zipper tapes from multiple angles compared with the prior art. It can not only detect missing zipper teeth, but also detect the shape of zipper teeth and related defects of pull tabs, greatly improving the functionality, accuracy and completeness of the inspection.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
