Description

Technical Field

[0001] This application relates to the field of zipper inspection technology, and more specifically, to a zipper visual full inspection labeling machine. Background Technology

[0002] As a key accessory widely used in clothing, bags, and footwear, the quality of zippers directly affects the performance and user experience of the final product. With the continuous improvement of product quality requirements in the manufacturing industry, zippers must undergo strict quality inspection during the production process to ensure that there are no defects such as missing teeth, crooked teeth, damaged fabric tape, color difference, or difficulty in zipping. In the zipper production process, quality inspection is a crucial link that directly affects the quality and performance of the product.

[0003] Currently, zipper quality inspection is mostly done manually. Inspectors visually inspect the zipper's appearance and structure to see if it meets the requirements. However, manual inspection has many drawbacks. On the one hand, the inspection efficiency is low and it is difficult to meet the needs of large-scale production. On the other hand, due to the subjective factors of the operators, such as fatigue and lack of concentration, it is easy to miss or misjudge, resulting in defective products entering the market and affecting the company's reputation and economic benefits. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a visual full-inspection labeling machine for zippers, which aims to improve the low efficiency of manual inspection, which is difficult to meet the needs of large-scale production and is prone to missed inspections and misjudgments.

[0005] This application provides a zipper visual inspection and labeling machine, including a frame. The upper end of the frame's inner cavity is equipped with a feeding and alarm mechanism for guiding zippers into the machine. Below the feeding and alarm mechanism, the inner cavity of the frame is equipped with a centering mechanism for positioning the zippers. Below the centering mechanism, the inner cavity of the frame is equipped with a detection mechanism for detecting the zipper position and determining whether it meets production requirements. Above the detection mechanism is a positioning mechanism for locating the starting detection position of each zipper. The bottom right side of the inner cavity of the frame is equipped with a feeding mechanism for driving the zippers to move. The inner cavity of the frame is also equipped with a marking mechanism for marking defective zippers.

[0006] In one specific implementation, the feeding and alarm mechanism includes a first wheel, a second wheel, a third wheel, a lever, a spring, and a proximity sensor. The first wheel, the third wheel, the spring, and the proximity sensor are all fixedly connected to the inner cavity of the frame by bolts. The second wheel is fixedly connected to the front of the lever by bolts. One end of the spring is fixedly connected to one side of the lever by bolts.

[0007] In the above implementation process, the control unit of the feeding and alarm mechanism consists of a servo motor and a controller, which is connected via a proximity sensor. The servo motor is connected to the servo controller. The zipper passes over the surface of the first wheel and enters the system. After the knotted zipper enters the system, it first passes through the first wheel. The distance between the two wheel pieces of the first wheel is less than the width of the knotted zipper, so it will jam the knotted part and prevent it from passing through the first wheel. Under the pull of the control unit and the braking of the first wheel, the second wheel will be subjected to the tension force of the zipper itself, which will exert a force on the main support. The lever will approach the proximity sensor under the influence of the lever force. After the proximity sensor detects the abnormal tension, it will transmit a signal to the servo control unit, which will know that the zipper has been knotted and jammed. It will then send a braking signal to the servo motor, thereby protecting the zipper from wear and protecting the servo system.

[0008] In one specific implementation, the centering mechanism includes a positioning plate for left and right positioning of the zipper and a pressing wheel for up and down positioning of the zipper, both of which are bolted to the inner cavity of the frame.

[0009] In the above process, the positioning plate is used to limit the zipper in the left and right directions, and the pressure roller is used to limit the zipper in the up and down directions. The two work together to achieve the positioning effect of the zipper and ensure that the zipper is transported smoothly.

[0010] In one specific implementation, the detection mechanism includes two cameras and two fill lights, with the cameras and fill lights on both sides operating alternately.

[0011] In the above implementation process, the camera captures images of each position of the zipper and then transmits them to the industrial control computer. The detection software performs the detection to determine whether the production requirements are met, and judges NG / OK. The NG position is calibrated. The supplementary light is used to supplement the light and improve the clarity of the captured image. The cameras on both sides and the supplementary light are used alternately to avoid the influence of opposite light sources.

[0012] In one specific implementation, the detection mechanism further includes a moving module for adjusting the position of the camera and a marking scale for reference of the position. The fill light, the moving module, and the marking scale are all bolted to the inner cavity of the frame. The moving module drives the camera to move via an electric cylinder, and the marking scale is located within the camera's shooting range.

[0013] In the above implementation process, when calibrating the camera position, the pixel position of the marker scale in the images of the two cameras is observed through the images of the two cameras. The camera is moved by activating the electric cylinder in the moving module so that the marker scale meets the required pixel position relationship, thus completing the relative position calibration of the two cameras.

[0014] In one specific implementation, the positioning mechanism includes a detection component, a first support frame, an electromagnetic cylinder, and a hook. The detection component is bolted to the inner cavity of the frame below the pressure wheel. The first support frame is bolted to the inner cavity of the frame. The electromagnetic cylinder is bolted to the inner cavity of the first support frame. The hook is fixedly connected to the output end of the electromagnetic cylinder.

[0015] In the above process, the zipper itself has multiple through holes at equal intervals. The detection component detects the position of the through holes, records it as the starting point, and transmits the detection result to the controller. The controller starts the electromagnetic cylinder according to the signal, so that the electromagnetic cylinder drives the hook to move and perform the positioning work of the zipper.

[0016] In one specific implementation, the marking mechanism is a punching mechanism for punching and marking zippers. The punching mechanism includes a second support frame, a cylinder, a punching component, and a positioning frame. The second support frame is bolted to the inner cavity of the frame. The cylinder is fixedly connected to one side of the second support frame by bolts. The punching component is fixedly connected to the output end of the cylinder. The positioning frame is welded to the surface of the second support frame. One end of the punching component passes through the positioning frame and is movably connected to its inner cavity.

[0017] In the above process, the zipper passes through the interior of the positioning frame, which can limit the zipper. The cylinder is controlled by the controller, and its output end can drive the punching part to move when it extends and retracts, so that the punching part can punch holes and mark the zipper.

[0018] In one specific implementation, the labeling mechanism is a labeling mechanism for labeling zippers. The labeling mechanism includes an automatic labeling machine for labeling zippers and a pad for supporting zippers. The automatic labeling machine is bolted to the back of the inner cavity of the frame, and the pad is bolted to the bottom of the inner cavity of the frame.

[0019] In the above process, the automatic labeling machine is used to label the defective parts of the zipper when the single piece is detected as NG, and the pad serves as a support.

[0020] In one specific implementation, the feeding mechanism includes a third support frame, a servo geared motor, rubber-coated wheels, synchronous pulleys, and a synchronous belt. The third support frame is fixedly connected to the inner cavity of the machine frame by bolts. The servo geared motor is fixedly connected to the back of the third support frame by bolts. The rubber-coated wheels are located on the front of the third support frame. The output shaft of the servo geared motor passes through the third support frame and is connected to the rubber-coated wheels for transmission. There are three synchronous pulleys, all of which are movably connected to the front of the rubber-coated wheels by bearings. The synchronous belt is sleeved on the surface of the three synchronous pulleys and is slidably connected to their surfaces. The synchronous belt is also movably connected to the surface of the rubber-coated wheels.

[0021] In the above implementation process, the servo geared motor is used to drive the rubber-coated wheel to rotate. With the cooperation of three synchronous pulleys and a synchronous belt, the zipper can be pressed tightly against the surface of the rubber-coated wheel, so that it can move with the rotation of the rubber-coated wheel and play the role of active feeding.

[0022] In one specific implementation, four lower guide wheels for guiding the zipper are movably connected to the lower back of the inner cavity of the frame via bearings. Each electrical component is connected to a controller and is automatically controlled by the controller.

[0023] In the above process, the lower guide wheel is used to support and guide the zipper, and the operation of the electrical components is controlled by the controller, which can effectively save manpower.

[0024] Compared with existing technologies, the beneficial effects of this application are as follows: By automatically detecting zipper quality and automatically marking defective products, the traditional manual inspection method is replaced, which greatly improves the inspection efficiency and can meet the needs of large-scale production. By adopting visual inspection technology and automated control, missed inspections and misjudgments caused by the subjective reasons of operators are avoided, thereby improving the accuracy and yield of inspection. At the same time, the close cooperation and precise positioning between the various mechanisms ensure the effectiveness of inspection and labeling, improve the reliability and stability of the equipment, and the reasonable structural design of the equipment allows the position and parameters of each mechanism to be adjusted according to different specifications of zippers, thus having strong versatility.

Detailed Implementation

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Please see Figure 1-9 This application provides a zipper visual inspection and labeling machine, including a frame 1. The upper end of the inner cavity of the frame 1 is provided with a feeding and alarm mechanism 2 for guiding zippers into the machine. The inner cavity of the frame 1 and below the feeding and alarm mechanism 2 is provided with a centering mechanism 3 for positioning the zippers. The inner cavity of the frame 1 and below the centering mechanism 3 is provided with a detection mechanism 4 for detecting the position of the zippers and determining whether they meet production requirements. Above the detection mechanism 4 is a positioning mechanism 5 for positioning the starting detection position of each zipper. The bottom right side of the inner cavity of the frame 1 is provided with a feeding mechanism 8 for driving the zippers to move. The inner cavity of the frame 1 is provided with a marking mechanism for marking defective zippers.

[0038] In its specific configuration, the feeding and alarm mechanism 2 includes a first wheel 201, a second wheel 202, a third wheel 203, a lever 204, a spring 205, and a proximity sensor 206. The first wheel 201, the third wheel 203, the spring 205, and the proximity sensor 206 are all bolted to the inner cavity of the frame 1. The second wheel 202 is bolted to the front of the lever 204. One end of the spring 205 is bolted to one side of the lever 204. The control unit of the feeding and alarm mechanism 2 consists of a servo motor and a controller, connected via the proximity sensor 206. The servo motor is connected to the servo controller. The zipper passes over the surface of the first wheel 201 and enters the system. When the knotted zipper enters the system, it first passes through wheel 1 201. The distance between the two wheel pieces of wheel 1 201 is less than the width of the knotted zipper, so it will jam the knotted part and prevent it from passing through wheel 1 201. Under the pull of the control unit and the braking of wheel 1 201, wheel 202 will be subjected to the tension force of the zipper itself and exert a force on the main support. Lever 204 will approach the proximity sensor 206 under the influence of the lever force. After the proximity sensor 206 detects the abnormal tension, it will transmit a signal to the servo control unit, which will know that the zipper is knotted and jammed, and will send a braking signal to the servo motor, thereby protecting the zipper from wear and protecting the servo system.

[0039] In a specific configuration, the centering mechanism 3 includes a positioning plate 301 for left and right positioning of the zipper and a pressing wheel 302 for up and down positioning of the zipper. Both the positioning plate 301 and the pressing wheel 302 are bolted to the inner cavity of the frame 1. The positioning plate 301 is used to limit the left and right direction of the zipper, and the pressing wheel 302 is used to limit the up and down direction of the zipper. The two work together to achieve the positioning effect of the zipper and ensure that the zipper is transported smoothly.

[0040] In the specific setup, the detection mechanism 4 includes a camera 401 and a supplementary light 402. There are two cameras 401 and two supplementary lights 402. The cameras 401 and supplementary lights 402 on both sides operate alternately. The camera 401 detects each position of the zipper by shooting to determine whether it meets the production requirements, judges NG / OK, and marks the NG position. The supplementary light 402 is used to supplement light and improve the clarity of the shooting image. The alternating use of the cameras 401 and supplementary lights 402 on both sides can avoid the influence of opposing light sources.

[0041] In a specific configuration, the detection mechanism 4 also includes a moving module 403 for adjusting the position of the camera 401 and a marker scale 404 for position reference. The supplementary light 402, the moving module 403, and the marker scale 404 are all bolted to the inner cavity of the frame 1. The moving module 403 drives the camera 401 to move via an electric cylinder. The marker scale 404 is located within the shooting range of the camera 401. When calibrating the position of the camera 401, the pixel position of the marker scale 404 in the images of the two cameras 401 is observed through the images of the two cameras 401. By activating the electric cylinder in the moving module 403 to move the camera 401, the marker scale 404 meets the required pixel position relationship, thus completing the relative position calibration of the two cameras 401.

[0042] In its specific configuration, the positioning mechanism 5 includes a detection component 501, a first support frame 502, an electromagnetic cylinder 503, and a hook 504. The detection component 501 is bolted to the inner cavity of the frame 1 below the pressure wheel 302. The first support frame 502 is bolted to the inner cavity of the frame 1. The electromagnetic cylinder 503 is bolted to the inner cavity of the first support frame 502. The hook 504 is fixedly connected to the output end of the electromagnetic cylinder 503. The zipper itself has multiple through holes at equal intervals. The detection component 501 detects the position of the through holes, records it as the starting point, and transmits the detection result to the controller. The controller starts the electromagnetic cylinder 503 according to the signal, causing the electromagnetic cylinder 503 to drive the hook 504 to move, thereby performing the positioning work of the zipper.

[0043] In its specific configuration, the feeding mechanism 8 includes a third support frame 801, a servo geared motor 802, a rubber-coated wheel 803, a synchronous pulley 804, and a synchronous belt 805. The third support frame 801 is bolted to the inner cavity of the frame 1. The servo geared motor 802 is bolted to the back of the third support frame 801. The rubber-coated wheel 803 is located on the front of the third support frame 801. The output shaft of the servo geared motor 802 passes through the third support frame 801 and is connected to the rubber-coated wheel 803 for transmission. The number of synchronous pulleys 804 is [number missing]. Three synchronous pulleys 804 are movably connected to the front of the rubber-coated wheel 803 via bearings. A synchronous belt 805 is fitted onto the surface of the three synchronous pulleys 804 and slidably connected to their surfaces. The synchronous belt 805 is also movably connected to the surface of the rubber-coated wheel 803. A servo reduction motor 802 is used to drive the rubber-coated wheel 803 to rotate. With the cooperation of the three synchronous pulleys 804 and the synchronous belt 805, the zipper can be pressed tightly against the surface of the rubber-coated wheel 803, so that it can move with the rotation of the rubber-coated wheel 803 and play the role of active material feeding.

[0044] In the specific setup, four lower guide wheels are movably connected to the lower back of the inner cavity of the frame 1 via bearings to guide the zipper. Each electrical component is connected to the controller and is automatically controlled by the controller. The lower guide wheels are used to support and guide the zipper. By controlling the operation of the electrical components through the controller, manpower can be effectively saved.

[0045] like Figure 8 As shown, this is the first embodiment of the marking mechanism. The marking mechanism is a punching mechanism 6 used to punch and mark zippers. The punching mechanism 6 includes a second support frame 601, a cylinder 602, a punching component 603, and a positioning frame 604. The second support frame 601 is bolted to the inner cavity of the frame 1. The cylinder 602 is fixedly connected to one side of the second support frame 601 by bolts. The punching component 603 is fixedly connected to the output end of the cylinder 602. The positioning frame 604 is welded to the surface of the second support frame 601. One end of the punching component 603 passes through the positioning frame 604 and is movably connected to its inner cavity. The zipper passes through the interior of the positioning frame 604, and the positioning frame 604 can limit the zipper. When the detection mechanism 4 detects the zipper and issues an NG command, the punching mechanism 6 can punch and mark the zipper. The cylinder 602 is controlled by a controller. When its output end extends or retracts, it can drive the punching component 603 to move, so that the punching component 603 punches and marks the zipper.

[0046] like Figure 3 As shown, this is a second embodiment of the marking mechanism, which is a labeling mechanism 7 for labeling zippers. The labeling mechanism 7 includes an automatic labeling machine 701 for labeling zippers and a pad 702 for supporting zippers. The automatic labeling machine 701 is bolted to the back of the inner cavity of the frame 1, and the pad 702 is bolted to the bottom of the inner cavity of the frame 1. When the detection mechanism 4 issues an NG command after detecting the zipper, the labeling mechanism 7 can label the zipper. The automatic labeling machine 701 can label the defective position of a single piece of material that is detected as NG, and the pad 702 serves as a support.

[0047] Ultimately, this solution can be adapted to use either a punching mechanism 6 or a labeling mechanism 7 to mark defects in zippers, depending on the actual usage requirements.

[0048] The working principle of this zipper visual full inspection and labeling machine is as follows: The zipper enters the system through the feeding and alarm mechanism 2. While guiding the zipper, the feeding and alarm mechanism 2 can detect whether the zipper is knotted. If knotted, it will automatically brake. If knotted, the zipper can continue to be conveyed. When the zipper passes through the centering mechanism 3, the positioning plate 301 and the pressure wheel 302 cooperate to position the zipper and ensure that it is smoothly conveyed to the subsequent unit. The positioning mechanism 5 is used to detect the starting position of each zipper. The detection mechanism 4 is used to determine whether the production requirements are met, and to determine NG / OK. The NG position is marked. Single pieces judged as OK can pass directly. Single pieces marked as NG are punched or labeled at the defect position of the zipper by the punching mechanism 6 or the labeling mechanism 7 of the marking mechanism. The zipper is finally discharged from the system through the unloading mechanism 8.

[0049] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
