Description

Technical Field

[0001] This invention relates to the field of zipper appearance inspection technology, specifically to an appearance inspection device for alloy zipper production. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items. They are widely used in clothing, bags, tents, etc. During the production of zippers, defects such as dirt on the rubber handle, shrinkage, shine, peeling, burrs, large parting lines, shearing, and uneven sprue are inevitable; while zinc parts may have defects such as dirt, scratches, dents, and diameter deformation. Traditional zipper appearance and size inspection mainly relies on manual full inspection, which involves detecting a wide variety of defects, resulting in low work efficiency, time and labor costs, and a high risk of missed or false inspections. To improve the efficiency of zipper appearance inspection, a machine vision-based zipper appearance and size inspection device, such as the one disclosed in CN216144714U, has been designed. This device uses a rotating conveyor turntable to perform various inspections on the zipper appearance in conjunction with a vision inspection mechanism, thereby improving the efficiency of zipper appearance inspection and reducing the labor intensity of workers. In the aforementioned prior art, although the appearance of the zipper can be quickly inspected, the zipper is not laid flat on the conveyor turntable when the appearance of the zipper is inspected, which can easily lead to inspection errors and cannot improve the accuracy of the inspection. In addition, when conducting inspections through a visual inspection mechanism containing a CCD camera, if the rotation speed of the conveyor turntable is too fast, the visual inspection mechanism will be unable to effectively perform image inspections, while if the rotation speed of the conveyor turntable is too low, the inspection efficiency will be reduced. Therefore, an appearance inspection device for alloy zipper production is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide an appearance inspection device for alloy zipper production, so as to solve the problems mentioned in the background art that the existing alloy zipper appearance inspection devices cannot ensure that the zipper is in a flat state when inspecting the zipper, and cannot improve the inspection efficiency while ensuring the inspection effect.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An appearance inspection device for alloy zipper production includes a base and a sleeve fixedly connected to its upper surface. The upper surface of the base is also provided with a feeding box angularly distributed about the sleeve's axis, and a fixing frame is mounted on the feeding box. The fixing frame is arc-shaped and has mounting arms angularly distributed on it. A ring plate is slidably connected to the upper surface of the sleeve via a sliding block structure. A mounting tube coaxial with the ring plate is fixedly passed through the ring plate, and a mounting shaft coaxial with the mounting tube is movably passed through the mounting tube. High-pressure air nozzles are provided on the upper middle part of the mounting shaft and on the mounting arms. A star-shaped frame is fixedly connected to the upper end of the mounting shaft, and a CCD camera is mounted on each lower end of the star-shaped frame. An air suction plate is provided below the ring plate and fixedly connected to the inner side of the upper end of the sleeve. A flattening mechanism is provided between the ring plate and the air suction plate. A self-adjusting transmission mechanism is connected to the flattening mechanism, and the self-adjusting transmission mechanism is connected to the outer side of the lower end of the mounting tube via a worm gear structure. The lower end of the mounting tube is connected to the upper surface of the base via a bearing.

[0005] Preferably, the high-pressure air nozzles are configured in a one-to-one correspondence with the feeding box, and only the position where the high-pressure air nozzles are set on the mounting shaft is not provided with a mounting arm, which facilitates the feeding of the zipper to be tested into the ring plate.

[0006] Preferably, the angle between the CCD camera and the adjacent high-pressure air nozzle is 30°.

[0007] Preferably, the flattening mechanism includes densely distributed air holes on the ring plate, and the upper end of the air suction plate has air suction holes distributed at equal angles with the same number of CCD camera groups, and each group of air suction holes is distributed in a fan shape, with each fan-shaped air suction hole located below its corresponding CCD camera.

[0008] Preferably, the flattening mechanism further includes an air pump installed on the upper surface of the base, and the air pump is located inside the sleeve. The output end of the air pump is connected to an exhaust pipe, and the input end of the air pump is connected to two air chamber pipes through a connecting pipe. The two air chamber pipes are connected to the suction plate through a Y-shaped suction pipe.

[0009] Preferably, the self-adjusting transmission mechanism includes a motor mounted on the upper surface of the base, and the motor is also located inside the sleeve. The two air chambers are respectively connected by bearings to a first conical tube and a second conical tube. The piston ends of corresponding piston rods are seamlessly slidably connected inside the two air chambers, and the rod ends of the two piston rods are respectively movably extended into the first conical tube and the second conical tube. A spring is provided between the inner top end of the first conical tube and the rod end of the corresponding piston rod.

[0010] Preferably, the first and second tapered tubes are arranged parallel to each other and have opposite orientations. The end of the first tapered tube facing away from the air chamber tube is connected to the motor via a belt drive mechanism. The worm portion of the worm gear structure is connected to the end of the second tapered tube facing away from the air chamber tube. The end of the first tapered tube connected to the belt drive mechanism and the shaft end of the worm portion of the worm gear structure are connected via a support plate. The support plate is connected to the worm portion and the end of the first tapered tube by bearings, and the support plate is supported on the upper surface of the base inside the sleeve.

[0011] Preferably, the first and second tapered tubes are provided with three strip-shaped through slots at equal angles. Each piston rod has three support bars distributed at equal angles at its rod end, and the support bars extend into the corresponding strip-shaped through slots. A corresponding support flat tube is sleeved on the outside of the support bar, and the support flat tube extends out of the corresponding strip-shaped through slot. An arc-shaped support block is fixedly connected to the end of each support flat tube extending out of the strip-shaped through slot. The support blocks on the first and second tapered tubes are connected by a belt for transmission between the first and second tapered tubes.

[0012] Preferably, the support block is further provided with rollers, and the first tapered tube and the second tapered tube are tactilely connected to the corresponding rollers to ensure the stability of the support block when it moves.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the appearance inspection device for alloy zipper production can not only ensure that the zipper is laid flat on the ring plate when inspected by the CCD camera, but also automatically reduce the rotation speed of the ring plate when the zipper passes the CCD camera, thereby balancing inspection efficiency and inspection effect, and avoiding the ring plate rotating too fast, which would prevent the CCD camera from effectively inspecting the appearance of the zipper. 1. The air pump generates suction through the suction holes on the suction plate, causing the zipper on the ring plate to be attracted to the ring plate when it passes through the suction holes, thus making it easier for the zipper to be laid flat on it and ensuring the accuracy of the test results. 2. When a section of the zipper passes the suction hole on the suction plate, it partially blocks the air vents on the ring plate, resulting in insufficient air intake. This creates negative pressure in the air chamber, causing the piston rod to gradually move into the corresponding air chamber. The support block also moves synchronously, changing the diameter of the support structures at both ends of the belt. This reduces the rotation speed of the mounting tube, thereby lowering the rotation speed of the ring plate. This facilitates the CCD camera's inspection of the zipper. During the process, the spring is stretched. After the zipper passes the CCD camera, the suction hole on the suction plate is no longer blocked. Under the spring's reset action, the belt resets, increasing the rotation speed of the ring plate. This balances inspection efficiency and inspection effect. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-8 The present invention provides the following technical solution: Example 1: To address the problem that previous alloy zipper appearance inspection devices could not guarantee that the zipper would be laid flat on the conveyor turntable, resulting in inaccurate inspection results, the following technical solution is provided: An appearance inspection device for alloy zipper production includes a base 1 and a sleeve 2 fixedly connected to its upper surface. The upper surface of the base 1 is also provided with a feeding box 3 angularly distributed about the axis of the sleeve 2, and a fixing frame 4 is mounted on the feeding box 3. The fixing frame 4 is arc-shaped, and mounting arms 5 are angularly distributed on the fixing frame 4. The upper surface of the sleeve 2 is connected by a sliding... The groove slider structure 15 is slidably connected to the ring plate 10. The ring plate 10 is fixedly connected to the mounting tube 16, which is coaxial with it. The mounting tube 16 is movably connected to the mounting shaft 9, which is coaxial with it. The upper middle part of the mounting shaft 9 and the mounting arm 5 are both provided with high-pressure air nozzles 6. The upper end of the mounting shaft 9 is fixedly connected to the cross bracket 7, and each lower end of the cross bracket 7 is equipped with a CCD camera 8. The ring plate 10 is provided with a suction plate 14 below it, and the suction plate 14 is fixedly connected to the inner side of the upper end of the sleeve 2. A flattening mechanism is provided between the ring plate 10 and the suction plate 14.

[0018] The high-pressure air nozzle 6 is set in a one-to-one correspondence with the feeding box 3, and only the mounting shaft 9 is set in the position of the high-pressure air nozzle 6 without the mounting arm 5, so that the zipper to be tested can be sent into the ring plate 10. The angle between the CCD camera 8 and the adjacent high-pressure air nozzle 6 is 30°.

[0019] The flattening mechanism includes densely distributed ventilation holes on the ring plate 10. The upper end of the air suction plate 14 has the same number of air suction holes as the CCD camera 8 at equal angles, and each group of air suction holes is arranged in a fan shape. Each fan-shaped air suction hole is located below its corresponding CCD camera 8. The flattening mechanism also includes an air pump 11 installed on the upper surface of the base 1. The air pump 11 is located inside the sleeve 2. The output end of the air pump 11 is connected to an exhaust pipe 19, and the input end of the air pump 11 is connected to two air chamber pipes 25 through a connecting pipe 20. The two air chamber pipes 25 are connected to the air suction plate 14 through a Y-shaped air suction pipe 21.

[0020] according to Figures 3-5 The motor 12 is started, and the first tapered tube 18 is driven to rotate through the belt drive mechanism 13. Then, the second tapered tube 23 is driven to rotate through the belt 24, and the mounting tube 16 is driven to rotate through the worm gear structure 17. When the mounting tube 16 rotates, the ring plate 10 rotates with it. Then the air pump 11 is started, which causes the air pump 11 to generate suction at the air intake hole on the air intake plate 14, thereby sucking in the dust in the air, and passing through the air intake pipe 21, the air chamber pipe 25 and the connecting pipe 20 in sequence, and finally being discharged through the exhaust pipe 19. During testing, a section of the zipper to be tested is placed on the ring plate 10 for conveying. When the zipper passes under the CCD camera 8, it will block the air suction hole on the suction plate 14, which will cause the zipper to be adsorbed on the ring plate 10, that is, to make the zipper flat on the ring plate 10, which helps to ensure the accuracy of the test. During the inspection of the zipper by the CCD camera 8, if any inspection item fails, the high-pressure air nozzle 6 behind it will be activated, thereby sending the zipper into the corresponding unloading box 3. If all inspection items of the zipper pass, it will be sent into the corresponding unloading box 3 through the high-pressure air nozzle 6 connected to the mounting shaft 9 when it is conveyed to the position of the high-pressure air nozzle 6.

[0021] Example 2: To solve the problem that previous alloy zipper appearance inspection devices could not balance inspection efficiency and inspection effect, the following technical solution is provided. Specifically, a self-adjusting transmission mechanism is connected to the flattening mechanism, and the self-adjusting transmission mechanism is connected to the lower outer side of the mounting tube 16 through the worm gear structure 17. The lower end bearing of the mounting tube 16 is connected to the upper surface of the base 1.

[0022] The self-adjusting transmission mechanism includes a motor 12 mounted on the upper surface of the base 1, and the motor 12 is also located inside the sleeve 2. A first conical tube 18 and a second conical tube 23 are respectively connected to two air chamber tubes 25 via bearings. The piston ends of corresponding piston rods 26 are seamlessly slidably connected inside each of the two air chamber tubes 25, and the rod ends of the two piston rods 26 extend movably into the first conical tube 18 and the second conical tube 23, respectively. Springs 27 are provided between the inner top ends of the first conical tube 18 and the second conical tube 23 and the rod ends of the corresponding piston rods 26. The first conical tube 18 and the second conical tube 23 are arranged parallel to each other and face opposite directions. The end of the first conical tube 18 facing away from the air chamber tube 25 is connected to the motor 12 via a belt drive mechanism 13. The worm portion of the worm gear structure 17 is connected to the end of the second conical tube 23 facing away from the air chamber tube 25. The end of the first conical tube 18 connected to the belt drive mechanism 13 and the shaft end of the worm portion of the worm gear structure 17 are supported by... The plates 22 are connected, and the support plate 22 is connected to the worm gear and the end of the first tapered tube 18 by bearings. The support plate 22 is supported on the upper surface of the base 1 inside the sleeve 2. The first tapered tube 18 and the second tapered tube 23 are provided with three strip-shaped through grooves at equal angles. Each piston rod 26 has three support bars 28 distributed at equal angles at the rod end. The support bars 28 extend into the corresponding strip-shaped through grooves. The outer side of the support bars 28 is fitted with a corresponding support flat tube 29, and the support flat tube 29 extends to the outside of the corresponding strip-shaped through groove. The end of each support flat tube 29 extending out of the strip-shaped through groove is fixedly connected to an arc-shaped support block 30. The support blocks 30 on the first tapered tube 18 and the second tapered tube 23 are connected by a belt 24 for transmission between the first tapered tube 18 and the second tapered tube 23. The support block 30 is also provided with a roller 31. The first tapered tube 18 and the second tapered tube 23 are rolledly connected to the corresponding roller 31 to ensure the stability of the support block 30 when it moves.

[0023] according to Figures 6-8 When the zipper passes under the CCD camera 8, it will not only flatten out, but also reduce the amount of gas entering the air intake plate 14 per unit time because the air intake hole on the air intake plate 14 is blocked. This will cause negative pressure to be generated in the air chamber tube 25, causing the corresponding piston rod 26 to move gradually into the air chamber tube 25. During this process, the spring 27 is stretched, and the structure composed of the support bar 28, the support flat tube 29 and the support block 30 will also move synchronously, thereby changing the transmission ratio of the first cone tube 18 and the second cone tube 23, which helps to reduce the rotation speed of the mounting tube 16. The rotation speed of the ring plate 10 is reduced by reducing the rotation speed of the mounting tube 16, so that the speed at which the zipper passes through the CCD camera 8 is reduced, ensuring that the CCD camera 8 can fully capture images of the zipper and ensure its detection effect. After the zipper passes the CCD camera 8, the air intake hole on the air intake plate 14 is no longer blocked. The rotation speed of the ring plate 10 can be restored by the reset of the spring 27, thereby improving the detection efficiency. When detecting a zipper using the CCD camera 8, the conveying speed of the zipper is reduced, and its conveying efficiency is increased after the zipper passes the CCD camera 8, thus balancing detection efficiency and detection effect.
