Description

Technical Field

[0001] The utility model relates to a zipper tape detection device, and more specifically to an ultrasonic cutting detector. Background Art

[0002] After the zipper tape is produced, it is necessary to detect the teeth of the produced zipper tape to check whether there are missing teeth on the zipper tape and whether the shape of the teeth is qualified.

[0003] At present, most of the tooth detection in the prior art is carried out by a detection device. For example, the utility model patent with the publication number of CN221631712U and the name of a tooth detection device discloses the detection of missing teeth by setting a detection component. When the detection component is detecting, the detection of missing teeth is carried out through the movement of the moving part. However, in the above detection process, only the detection of missing teeth can be realized. When the shape of the teeth is unqualified, it cannot be effectively detected simply by the movement of the moving part. Therefore, the existing detection device cannot realize the detection of defects other than missing teeth, and there are deficiencies in functionality. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an ultrasonic cutting detector that can realize the detection of defects other than missing teeth.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an ultrasonic cutting detector, including a frame and a chain guiding device, a front tape pulling device, a detection device, a rear tape pulling device, and an ultrasonic cutting device that are sequentially arranged on the frame. The zipper tape is introduced through the chain guiding device, introduced through the front tape pulling device, detected by the detection device, and then pulled out by the rear tape pulling device and sent to the ultrasonic cutting device for cutting. The detection device includes a detection bracket and a camera assembly installed on the detection bracket. A guiding component is arranged on the detection bracket, and the guiding component guides the zipper tape to pass through the shooting area of the camera assembly, and the camera assembly shoots and detects the defects of the zipper tape.

[0006] As a further improvement of the utility model, the guiding component is a plurality of guide wheels that are rotatably arranged on the detection bracket, and the camera assembly is arranged between two adjacent guide wheels, so that the zipper tape bypassing the guide wheels passes through the shooting area of the camera assembly.

[0007] As a further improvement of the utility model, the detection bracket is a frame structure, and a plurality of guide wheels are respectively arranged at the four corners of the detection bracket one by one. At least two camera assemblies are provided and are respectively installed at the positions between the upper and lower adjacent guide wheels.

[0008] As a further improvement of the present invention, three camera assemblies are provided, wherein one camera assembly and a sunshade form a group to photograph one side of the zipper tape, and two camera assemblies form a group to photograph both sides of the zipper tape.

[0009] As a further improvement of the present invention, the detection device further comprises a pull-tab flipping assembly, the zipper tape passes through the pull-tab flipping assembly, and the pull-tab flipping assembly flips the slider pull-tab on the zipper tape.

[0010] As a further improvement of the present invention, the pull-tab flipping assembly includes a chain plate, a chain vertical plate and a flipping plate. The chain plate is fixedly mounted on the detection bracket, the chain vertical plate is vertically fixed above the chain plate, and the flipping plate is elastically and selectively mounted on the chain vertical plate. The lower end of the flipping plate and the upper side of the chain plate form a channel for the zipper tape to pass through. When the zipper tape passes through the channel, the flipping plate abuts against the pull tab on the slider, thereby driving the pull tab to flip.

[0011] As a further improvement of the utility model, it also includes a length measuring component, which is communicatively connected with the ultrasonic cutting device to drive the ultrasonic cutting device to cut the zipper tape after measuring the length of the zipper tape.

[0012] As a further improvement of the utility model, the length measuring assembly includes a measuring guide wheel and a measuring encoder. The measuring guide wheel is installed on the frame in a liftable manner. The zipper belt passes around from under the measuring guide wheel. The measuring encoder is provided with a pull rope, the end of which is connected to the measuring guide wheel and is pulled as the measuring guide wheel rises.

[0013] Beneficial effects of the utility model: Compared with the prior art in the background technology, which mostly adopts a single detection device and can only detect missing teeth, but cannot effectively detect other defects such as unqualified tooth shape, and has insufficient functionality. The utility model can shoot and detect various defects of the zipper tape including the shape of the tooth by setting a camera component combined with a guide component, which greatly improves the detection functionality; the pull tab flipping component can flip the pull tab to avoid covering the tooth to be detected by the pull tab; the length measurement component cooperates with the ultrasonic cutting device to accurately control the cutting length of the zipper tape, and the overall detection comprehensiveness and functionality are significantly advanced.

[0018] The following will further elaborate on the present utility model in combination with the embodiments given in the accompanying drawings.

[0019] Refer to Figure 1 As shown, the ultrasonic cutting detector of this embodiment includes a frame 1, and a chain guide device 2, a front pulling belt device 3, a detection device 4, a rear pulling belt device 5, and an ultrasonic cutting device 6 arranged in sequence on the frame 1. The zipper tape is introduced through the chain guide device 2, introduced through the front pulling belt device 3, detected by the detection device 4, and then pulled out through the rear pulling belt device 5 and sent to the ultrasonic cutting device 6 for cutting. The detection device 4 includes a detection bracket 41 and a camera assembly 42 installed on the detection bracket 41. A guiding component is provided on the detection bracket 41, and this guiding component guides the zipper tape to pass through the shooting area of the camera assembly 42. The camera assembly 42 shoots and detects defects of the zipper tape. Compared with the background art where only missing teeth can be detected, this solution can detect various defects of the zipper tape through shooting by the camera assembly 42, improving the detection functionality.

[0020] Refer to Figure 2 As shown, further, the guiding component is a number of guide wheels 43 rotatably arranged on the detection bracket 41. The camera assembly 42 is arranged between two adjacent guide wheels 43, so that the zipper tape bypassing the guide wheels 43 passes through the shooting area of the camera assembly 42. This setting facilitates guiding the zipper tape through the shooting area of the camera assembly 42 and ensures the smooth progress of detection.

[0021] Further, the detection bracket 41 is of a frame structure. A number of guide wheels 43 are respectively arranged at the four corners of the detection bracket 41 in one-to-one correspondence. At least two camera assemblies 42 are provided and are respectively installed at positions between two adjacent upper and lower guide wheels 43. Reasonably arranging the guide wheels 43 and the camera assembly 42 is beneficial to improving the comprehensiveness of detection. The camera assembly 42 in this embodiment is composed of one camera and one fill light.

[0022] Further, three camera assemblies 42 are provided. One camera assembly 42 and a light shield form a group to shoot one side of the zipper tape, and two camera assemblies 42 form a group to shoot both sides of the zipper tape. Multiple groups of camera assemblies 42 work together to detect the conditions on both sides and one side of the zipper tape more comprehensively, improving the detection effect.

[0023] Further, the detection device 4 further includes a tab flipping assembly 44. The zipper tape passes through the tab flipping assembly 44, and the tab flipping assembly 44 flips the pull tab on the zipper tape, facilitating the detection of the area covered by the pull tab and avoiding missed detections. For example, for a pull tab with elasticity, since the pull tab will be positioned after one flip, it is necessary to flip the pull tab through the action of the tab flipping assembly 44, so as to detect the area originally covered by the pull tab and avoid missed detections.

[0024] Refer to Figure 3 As shown, further, the tab flipping assembly 44 includes a chain passing plate 441, a chain passing vertical plate 442, and a flipping plate 443. The chain passing plate 441 is fixedly installed on the detection bracket 41. The chain passing vertical plate 442 is vertically fixed above the chain passing plate 441. The flipping plate 443 is elastically and selectively installed on the chain passing vertical plate 442. The lower end of the flipping plate 443 and the upper side of the chain passing plate 441 form a channel for the zipper tape to pass through. When the zipper tape passes through the channel, the flipping plate 443 abuts against the pull tab on the slider, thereby driving the pull tab to flip. This structure is simple and easy to implement, and can effectively realize the flipping of the pull tab. At the same time, in this embodiment, the elastic rotation of the flipping plate 443 is realized by connecting a tension spring to the upper end of the flipping plate 443.

[0025] Further, it further includes a length measuring assembly 7. The length measuring assembly 7 is communicatively connected to the ultrasonic cutting device 6 to measure the length of the zipper tape and then drive the ultrasonic cutting device 6 to cut the zipper tape, realizing the measurement of the length of the zipper tape and the automatic cutting control, and increasing the functions of the equipment.

[0026] Refer to Figure 4 As shown, further, the length measuring assembly 7 includes a measuring guide wheel 71 and a measuring encoder 72. The measuring guide wheel 71 is installed on the machine frame 1 in a liftable manner. The zipper tape bypasses the lower part of the measuring guide wheel 71. The measuring encoder 72 has a pulling rope, and the end of the pulling rope is connected to the measuring guide wheel 71 and is pulled as the measuring guide wheel 71 rises. This structure can accurately measure the length of the zipper tape and provide a basis for accurate cutting. During the measurement process, first, the measuring guide wheel 71 is set at a certain height by tensioning the zipper tape. Then, during the process of feeding the measured zipper tape into the ultrasonic cutting device 6, due to the transportation of the zipper tape, the zipper tape drives the measuring guide wheel 71 to descend to the height where cutting is required, and then the transportation stops. The height is measured by the length of the pulling rope pulled on the measuring encoder 72. After that, the ultrasonic cutting device 6 pulls the zipper tape, so that the tension of the zipper tape makes the measuring guide wheel 71 rise back to the previous height. At this time, the ultrasonic cutting device 6 cuts the discharged material, thus realizing the effect of measuring the length of the zipper tape to be cut through the length measuring assembly 7.

[0027] In summary, the ultrasonic cutting detector can detect various defects of the zipper tape by setting the camera assembly 42, improving the detection functionality; the reasonable layout of the guide wheels 43 and the camera assembly 42 improves the detection comprehensiveness; the tab flipping assembly 44 expands the detection range; the length measurement assembly 7 increases the functions of the device. Compared with the background technology that can only detect missing teeth and has insufficient functionality, it has significant advancement.

All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
