[0032] The beneficial effects of this utility model are:

[0033] (1) This utility model has a compact structure, occupies little space, and has a high space utilization rate. Through the cooperation of the feeding device, the picking robot, the detection device and the sorting mechanism, it can realize fully automatic feeding, picking and placing, defect detection and sorting, with high work efficiency and high detection quality, effectively reducing the production cycle and production cost.

[0034] (2) Pressing multiple transmission belts to be tested by pressing the material component avoids the transmission belts being messy and makes it easier to separate the transmission belts to be tested in sequence and to make it easier for the material taking mechanism to take the transmission belts.

[0058] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0059] Please see Figure 1 , Figure 2 , Figure 7 , Figure 10 , Figure 13An automatic defect inspection machine for transmission belts includes a feeding device 1, a picking robot 2, an inspection device 3, and a sorting mechanism. The feeding device 1 includes a turntable assembly 11 and multiple racks 12 circumferentially spaced on the turntable assembly 11 and drivable by the turntable assembly 11. The racks 12 are used to hold multiple transmission belts 5 to be inspected. The picking robot 2 includes a picking bracket 21, a horizontal drive mechanism 22 mounted on the picking bracket 21, and a picking mechanism 23 connected to the horizontal drive mechanism 22. The picking mechanism 23 includes a picking seat 231 and at least one picking component 232 disposed on the picking seat 231. The picking mechanism 23 can move horizontally relative to the picking bracket 21 under the drive of the horizontal drive mechanism 22 to grab the transmission belts 5 on the racks 12 and transfer the transmission belts 5 to the inspection device 3. The inspection device 3 includes an inspection frame 31 and an inspection mechanism disposed on the inspection frame 31. The inspection mechanism includes at least one inspection component 32, which is used to perform defect inspection on the conveyor belt 5 transferred by the material handling component 232. The sorting mechanism is used to transfer the conveyor belt 5 after being inspected by the inspection component 32 to the corresponding position.

[0060] Please see Figure 2 The turntable assembly 11 includes a turntable body 111 and a rotary drive mechanism 112. The rotary drive mechanism 112 is connected below the turntable body 111 and drives the turntable body 111 to rotate around its own central axis. One end of each material rack 12 is circumferentially spaced on the turntable body 111, and the other end extends radially out of the turntable body 111. Each material rack 12 includes a loading assembly 121, a transfer assembly 122, a pusher assembly 123, and a pressing assembly 124. The loading assembly 121 is used to hang multiple transmission belts 5 to be tested. The transfer assembly 122 is connected to the end of the loading assembly 121. The pusher assembly 123 is used to push the multiple transmission belts 5 on the loading assembly 121 sequentially to the transfer assembly 122 to wait for the picking assembly 232 to grab. The pressing assembly 124 is located above the loading assembly 121. The feeding device 1 also includes multiple workstations, including a material preparation station 13, a waiting station 14 and a feeding station 15. Multiple material racks 12 correspond to multiple workstations. The turntable assembly 11 drives the multiple material racks 12 to stop or pass through multiple workstations.

[0061] Please see Figure 2 , Figure 3 , Figure 4The material loading assembly 121 includes a support arm 1211, two horizontally arranged material loading rods 1212, and a side plate 1213. The support arm 1211 is cantilevered, with one end mounted to the turntable body 111 and the other end extending radially out of the turntable body 111 and mounted on the side plate 1213. The material loading rods 1212 are parallel to the support arm 1211 and located above it. One end of each material loading rod 1212 is connected to the turntable body 111 or the support arm 1211, and the other end is connected to the side plate 1213. This arrangement improves the stability of the installation of the two material loading rods 1212 and the transfer assembly 122, ensuring the smoothness and stability of the transmission belt 5 moving along the two material loading rods 1212 and the stability of the transmission belt 5 falling onto the transfer assembly 122.

[0062] In this embodiment, the transfer assembly 122 includes two horizontally arranged transfer brackets 1221. One end of each transfer bracket 1221 is fixedly mounted on a side plate 1213. The material carrier 1212 and the transfer brackets 1221 are located on the inner and outer sides of the side plate 1213, respectively. The other end of each transfer bracket 1221 is a free end. The inner and outer directions refer to the direction of movement along the transmission belt 5. Thus, by pushing the material pusher 123, the transmission belt 5 is pushed away from the two material carriers 1212, and the transmission belt 5 falls onto the two transfer brackets 1221, making it convenient for the material pick-up assembly 232 to remove the transmission belt 5. To prevent the transmission belt 5 from slipping off the transfer bracket 1221, it is preferable that the transfer bracket 1221 is provided with a limiting groove 1222. Specifically, the transfer bracket 1221 is rod-shaped, and the limiting groove 1222 is located on the upper part of the transfer bracket 1221. The front and rear ends of the upper limiting groove 1222 along the transmission direction are higher than the limiting groove 1222, so that the transmission belt 5 can be stopped at the limiting groove 1222 to prevent it from falling.

[0063] Please see Figure 2 , Figure 4 , Figure 5 The pushing assembly 123 includes a linear drive 1231 and a pushing component 1232 connected to and driven by the linear drive 1231. The pushing component 1232 can move along the two material carriers 1212 to push the transmission belt 5 forward one by one, hang on the transfer bracket 1221, and wait for the material picking mechanism 23 of the next process to pick it up.

[0064] Please see Figure 4 , Figure 5The linear drive component 1231 includes a first drive motor 12311, a first synchronous belt 12312, a drive pulley 12313 connected to the first drive motor 12311, and a driven pulley 12314 connected to the drive pulley 12313 via the first synchronous belt 12312. The material loading assembly 121 also includes a slide rail 1214 mounted on the support arm 1211 and a slider 1215 slidably connected to the slide rail 1214. The drive pulley 12313 and the driven pulley 12314 are located at opposite ends of the slide rail 1214. The slider 1215 is fixedly mounted on the first synchronous belt 12312, and the pusher 1232 is fixedly mounted on the slider 1215. The first drive motor 12311 drives the drive pulley 12313 to rotate, which in turn drives the first synchronous belt 12312 to move, thereby moving the slider 1215 and the pusher 1232 on the slider 1215. It is understood that in some other embodiments, the linear drive 1231 may also be a linear motor, a lead screw assembly, etc., and the specific structure of the linear drive 1231 is not limited here.

[0065] In this embodiment, the pusher 1232 includes a support plate 12321 and a pusher plate 12322 connected to the end of the support plate 12321 and extending vertically upward. The support plate 12321 is fixedly installed on the slider 1215. The pusher plate 12322 has through slots 12323 on both sides that cooperate with the two material carriers 1212. Each material carrier 1212 passes through the corresponding through slot 12323, which facilitates the movement of the pusher plate 12322 along the material carrier 1212.

[0066] To improve the stability of the pusher 1232, it is preferable that at least one reinforcing plate 12324 is connected between the pusher plate 12322 and the support plate 12321. Specifically, there are two reinforcing plates 12324.

[0067] In this embodiment, one end of the material carrier 1212 is connected to the turntable body 111. Specifically, one end of each material carrier 1212 is connected to an L-shaped seat 1216, which is mounted on the turntable body 111.

[0068] Please see Figure 2 , Figure 4The pressing assembly 124 includes a pressing frame 1241, at least one pressing cylinder 1242 disposed on the pressing frame 1241, and a pressing rod 1243 connected to and driven by the pressing cylinder 1242. The pressing frame 1241 is disposed on the turntable body 111, and the pressing rod 1243 is located above the loading assembly 121. Preferably, there are two pressing cylinders 1242, and the two pressing cylinders 1242 act on the same pressing rod 1243 simultaneously, which facilitates better driving of the pressing rod 1243 to press the transmission belt 5 to be tested and avoids the transmission belt 5 from becoming messy. Of course, it is understandable that the number of pressing cylinders 1242 can be adjusted as needed. For example, it can be set to three, with three pressing cylinders 1242 driving the same pressing rod 1243. Alternatively, it can be set to two pressing cylinders 1242 and two pressing rods 1243, with each pressing cylinder 1242 driving the corresponding pressing rod 1243. As long as it can press down multiple transmission belts 5, it is not limited here.

[0069] Please see Figure 2 , Figure 6 The rotary drive mechanism 112 includes a motor component 1121, a reducer 1122 connected to the motor component 1121, a divider 1123 connected to the reducer 1122, and a disk 1124 connected to the divider 1123. The central axis of the disk 1124 coincides with the central axis of the turntable body 111, and the turntable body 111 is connected above the disk 1124. It is understood that the rotary drive mechanism 112 may also adopt a structure of motor and gear assembly, or motor and worm gear assembly, etc., which is not limited here.

[0070] Preferably, multiple material racks 12 are evenly spaced along the circumference of the turntable body 111, with multiple workstations corresponding one-to-one with multiple material racks 12. In this embodiment, six material racks 12 and six workstations are provided, with each material rack 12 corresponding to one workstation. The six workstations include one material preparation position 13, four waiting positions 14, and one material loading position 15. At this time, the material preparation position 13 is positioned as close as possible to the material loading position 15 in the normal rotation direction of the turntable body 111 to prevent empty material racks 12 from rotating to the material loading position 15 due to lack of timely material preparation, thus ensuring continuous material loading.

[0071] Please see Figures 7-8The material handling assembly 232 includes a rotary drive 2321, a support member 2322 connected to the rotary drive 2321, a material handling member 2323 connected to the support member 2322, and two support members 2324. The rotary drive 2321 is connected to the material handling seat 231 and drives the support member 2322 to rotate horizontally. The material handling member 2323 is located between the two support members 2324. While the material handling member 2323 is handling the transmission belt 5, the two support members 2324 on both sides of the material handling member 2323 pass through the transmission belt 5 and support the transmission belt 5, which facilitates the rapid transfer of the transmission belt 5 to the detection assembly 32, enabling subsequent rapid detection of the transmission belt.

[0072] The material handling unit 231 includes a base plate 2311 and a vertical plate 2312 fixedly connected to the upper part of the base plate 2311. The upper part of the vertical plate 2312 is fixedly connected to the sliding part of the horizontal drive mechanism 22 and slides along the horizontal drive mechanism 22. A rotary drive member 2321 is connected to the lower part of the base plate 2311. The carrier member 2322 includes a carrier mounting plate 23221. The rotary drive member 2321 and the material handling member 2323 are both connected to the carrier mounting plate 23221 and are respectively located on two opposite surfaces of the carrier mounting plate 23221. Specifically, the rotary drive member 2321 is located on the upper surface of the carrier mounting plate 23221, and the material handling member 2323 is located on the lower surface of the carrier mounting plate 23221.

[0073] In this embodiment, the rotary drive 2321 is a rotary cylinder, the body of which is fixedly connected to the lower part of the base plate 2311, and the rotary table of which is fixedly connected to the support mounting plate 23221. It is understood that the rotary drive 2321 is not limited to a rotary cylinder, but can also be a hydraulic motor, a pneumatic motor, or a linear motor with a rack and pinion assembly.

[0074] In this embodiment, the material support component 2324 includes a material support rod 23241 and a push plate 23242 capable of horizontally moving along the material support rod 23241. The material support rod 23241 is fixedly connected to the support mounting plate 23221. A push-pull cylinder 23243 is provided on the support mounting plate 23221. The cylinder body of the push-pull cylinder 23243 is fixed to the support mounting plate 23221, and the cylinder rod of the push-pull cylinder 23243 is fixedly connected to the push plate 23242. When the material picker 2323 picks up material, the material support rod 23241 simultaneously passes through the transmission belt 5 and supports the transmission belt 5. When unloading and transferring to the detection component 32, the material support rod 23241 can also serve as a guide rod, facilitating the linearity of the push plate 23242's horizontal movement along the material support rod 23241 towards the detection component 32, and quickly pushing the transmission belt 5 to the detection component 32. When the push-pull cylinder 23243 is activated, the cylinder rod of the push-pull cylinder 23243 pushes the push plate 23242 to move horizontally along the support rod 23241, so as to quickly and smoothly push the transmission belt 5 to the detection component 32.

[0075] To achieve a more stable connection between the support rod 23241 and the load-bearing mounting plate 23221, please refer to [link / reference]. Figure 9 Preferably, a first support seat 23222 is fixedly connected to the lower surface of the support mounting plate 23221, and one end of the support rod 23241 is horizontally inserted and fixedly connected to the first support seat 23222. To better achieve a stable connection between the push-pull cylinder 23243 and the support mounting plate 23221, a second support seat 23223 is preferably fixedly connected to the support mounting plate 23221, and the cylinder body of the push-pull cylinder 23243 is fixed to the second support seat 23223. Preferably, the second support seat 23223 is inverted L-shaped. To better achieve a stable connection between the material taking component 2323 and the support mounting plate 23221, a support rod 23224 is preferably fixedly connected to the lower surface of the support mounting plate 23221, with a portion of the support rod 23224 extending out of the support mounting plate 23221, and the material taking component 2323 is installed at the end of the support rod 23224 that extends out of the support mounting plate 23221. To prevent interference with the rotary cylinder, the support rod 23224 can be installed on the lower surface of the support mounting plate 23221.

[0076] In this embodiment, the material handling component 2323 includes a gripper drive component 23231 and two grippers 23232 driven by the gripper drive component 23231 to perform up-and-down opening and closing movements, which facilitates quick clamping of the transmission belt to be tested.

[0077] Please refer to the following: Figure 7 The horizontal drive mechanism 22 includes a first horizontal moving mechanism 221 and a second horizontal moving mechanism 222 connected to the first horizontal moving mechanism 221. The first horizontal moving mechanism 221 is disposed on the material picking bracket 21, and the material picking mechanism 23 is connected to the second horizontal moving mechanism 222. The moving direction of the first horizontal moving mechanism 221 is perpendicular to the moving direction of the second horizontal moving mechanism 222. Both the first horizontal moving mechanism 221 and the second horizontal moving mechanism 222 are linear motors. It is understood that the first horizontal moving mechanism 221 and the second horizontal moving mechanism 222 can also adopt a combination structure of motor and synchronous belt, a motor with gear and rack structure, or a linear guide rail slider structure, which is not limited here. Specifically, the upper part of the upright plate 2312 is fixedly connected to the second horizontal moving mechanism 222.

[0078] To further improve the stability of the horizontal movement of the material handling mechanism 23, a guide component 24 is preferably provided on the material handling bracket 21. The guide component 24 is parallel to the first horizontal moving mechanism 221. The second horizontal moving mechanism 222 is fixed with a support base 25. One end of the support base 25 is movably connected to the first horizontal moving mechanism 221, and the other end of the support base 25 is movably connected to the guide component 24. The guide component 24 can be a combination structure of guide rail and slider.

[0079] Please see Figures 10-12 The detection component 32 includes a base 321, an image extraction component 322, and a drive component and an unloading component disposed on the base 321. The drive component includes a drive unit 3231, a first transmission component 3232 connected to and driven by the drive unit 3231, and a second transmission component 3233 connected to the first transmission component 3232. The second transmission component 3233 includes a first transmission pulley 32331 and a second transmission pulley 32332 arranged side by side, and a third transmission pulley 32333 located below the first transmission pulley 32331 and the second transmission pulley 32332. The first transmission pulley 32331 and the second transmission pulley 32332 are both connected to the first transmission component 3232, and the third transmission pulley 32333 can move in the vertical direction.

[0080] The base 321 is fixed on the inspection frame 31. The image extraction component 322 is used to acquire images of the transmission belt 5. The transmission belt 5 to be inspected is confined on the drive component and rotated by the drive component, which facilitates the comprehensive defect detection of the transmission belt 5 by the image extraction component 322. The transmission belt 5 to be inspected is sleeved and tensioned on the first transmission pulley 32331, the second transmission pulley 32332, and the third transmission pulley 32333. The first transmission component 3232 drives the first transmission pulley 32331 and the second transmission pulley 32332 to rotate, causing the transmission belt 5 to be inspected and the third transmission pulley 32333 to rotate, which facilitates the comprehensive and rapid acquisition of images of the transmission belt 5 by the image extraction component 322. The third transmission pulley 32333 can be adjusted in the vertical direction, which facilitates the installation and tensioning of transmission belts of different lengths on the first transmission pulley 32331, the second transmission pulley 32332 and the third transmission pulley 32333, and is suitable for the detection of transmission belts of different lengths.

[0081] Please see Figure 11 , Figure 12 The first drive pulley 32331 is a frustum-shaped cone, wider at the outer edge and narrower at the inner edge, while the second drive pulley 32332 is a frustum-shaped cone, narrower at the outer edge and wider at the inner edge. The use of two tapers in different directions causes the drive belt 5 to twist slightly as it passes through the first and second drive pulleys 32331 and 32332. This allows the image extraction component 322 to more clearly capture the side structure of the drive belt, facilitating the identification of defects such as whether the cords have separated from the rubber. The drive belt 5 to be inspected is picked up from the rack 12 and then fitted onto the first and second drive pulleys 32331 and 32332 in an outward-to-inward direction. It is understood that the first drive pulley 32331 can also be configured as a frustum-shaped cone, narrower at the outer edge and wider at the inner edge, in which case the second drive pulley 32332 would be a frustum-shaped cone, wider at the outer edge and narrower at the inner edge.

[0082] Please see Figure 11 , Figure 12The detection component 32 also includes a limiting component, which includes a first limiting member 3251 and a second limiting member 3252. The first limiting member 3251 includes a first limiting wheel 32511, which cooperates with a first transmission pulley 32331. The second limiting member 3252 includes a second limiting wheel 32521, which cooperates with a second transmission pulley 32332. Both the first limiting wheel and the second limiting wheel are conical. The first limiting wheel has a conical shape opposite to that of the first transmission pulley, and the second limiting wheel has a conical shape opposite to that of the second transmission pulley. When the first drive pulley 32331 is a frustum shape with a larger outer diameter and a smaller inner diameter, and the second drive pulley 32332 is a frustum shape with a smaller outer diameter and a larger inner diameter, the first limiting wheel 32511 is a cone shape with a smaller outer diameter and a larger inner diameter to match the first drive pulley 32331, and the second limiting wheel 32521 is a cone shape with a larger outer diameter and a smaller inner diameter to match the second drive pulley 32332. The setting of the first limiting wheel 32511 and the second limiting wheel 32521 can press down on the drive belt 5 to be tested, preventing the drive belt from arching after twisting, thus facilitating image acquisition. It is understandable that when the first transmission pulley 32331 is a frustum shape with a smaller outer diameter and a larger inner diameter, and the second transmission pulley 32332 is a frustum shape with a larger outer diameter and a smaller inner diameter, the first limiting pulley 32511 is a cone shape with a larger outer diameter and a smaller inner diameter to match the first transmission pulley 32331, and the second limiting pulley 32521 is a cone shape with a smaller outer diameter and a larger inner diameter to match the second transmission pulley 32332.

[0083] To facilitate the first limiting wheel 32511 and the second limiting wheel 32521 pressing against or separating from the transmission belt to be tested, the first limiting member 3251 preferably further includes a first rotary cylinder 32512. The first rotary cylinder 32512 is connected to and drives the first limiting wheel 32511, so that the first limiting wheel 32511 can cooperate with the outside of the first transmission pulley 32331 to limit its passage through the transmission belt between the first transmission pulley 32331 and the first limiting wheel 32511. The second limiting member 3252 further includes a second rotary cylinder 32522. The second rotary cylinder 32522 is connected to and drives the second limiting wheel 32521, so that the second limiting wheel 32521 can cooperate with the outside of the second transmission pulley 32332 to limit its passage through the transmission belt between the second transmission pulley 32332 and the second limiting wheel 32521. The fixed end of the first rotary cylinder 32512 is fixed, the first limiting wheel 32511 is rotatably connected to the output end of the first rotary cylinder 32512, the fixed end of the second rotary cylinder 32522 is fixed, and the second limiting wheel 32521 is rotatably connected to the output end of the second rotary cylinder 32522.

[0084] To remove impurities from the transmission belt for clearer image acquisition, it is preferable that the second rotary cylinder 32522 is connected to a brush 32523. The second rotary cylinder 32522 can drive the brush 32523 to press onto the transmission belt to be inspected or rotate it away from the transmission belt. It is understood that a brush can also be connected to the first rotary cylinder 32512, or both the first rotary cylinder 32512 and the second rotary cylinder 32522 can be connected to brushes.

[0085] Preferably, the drive unit 3231 includes a second drive motor 3234, and the first transmission assembly 3232 includes a first synchronous pulley 32321 driven by the second drive motor 3234, and a second synchronous pulley 32323 connected to the first synchronous pulley 32321 via a second synchronous belt 32322. The first synchronous pulley 32321 and the second synchronous pulley 32323 are respectively connected to the second transmission pulley 32332 and the first transmission pulley 32331.

[0086] The detection assembly 32 also includes a mounting plate 3261, a linear drive unit 3262 connected to the mounting plate 3261, and a support 3263 connected to the linear drive unit 3262. A third transmission pulley 32333 is rotatably connected to the support 3263. The mounting plate 3261 is fixed on the detection frame 31. The linear drive unit 3262 is a combination structure of a motor and a lead screw. It is understood that the linear drive unit 3262 can also be a linear motor, a motor and a gear and rack assembly, etc., which are not limited here. Driven by the linear drive unit 3262, the support 3263 drives the third transmission pulley 32333 to move in the vertical direction.

[0087] To achieve unloading after transmission belt inspection, the preferred unloading assembly includes two first unloading components 3241 arranged side by side, located on both sides of the second transmission assembly 3233. Each first unloading component 3241 includes a first unloading cylinder 32411 and an unloading rod 32412 connected to the first unloading cylinder 32411. Specifically, the two first unloading components 3241 are located on both sides of the first transmission pulley 32331 and the second transmission pulley 32332, respectively, for pushing the transmission belt 5 in the width direction. The fixed end of the first unloading cylinder 32411 is fixed to the base 321, and the output end of the first unloading cylinder 32411 drives the unloading rod 32412 to move outward, pushing the transmission belt away from the first transmission pulley 32331, the second transmission pulley 32332, and the third transmission pulley 32333.

[0088] To facilitate smoother unloading of the drive belt, the preferred unloading assembly further includes a second unloading component 3242 located above the two first unloading components 3241. The second unloading component 3242 includes a second unloading cylinder 32421 and an unloading block 32422 connected to the second unloading cylinder 32421. The fixed end of the second unloading cylinder 32421 remains stationary, while the output end of the second unloading cylinder 32421 drives the unloading block 32422 to move outward, further pushing the drive belt away from the first drive pulley 32331, the second drive pulley 32332, and the third drive pulley 32333.

[0089] The preferred image extraction component 322 includes four cameras, two of which are arranged horizontally opposite each other to capture images of the two sides of the transmission belt 5, and the other two are arranged vertically opposite each other to capture images of the back and bottom surfaces of the transmission belt 5. It is understood that the number of cameras is not limited to four; five or more cameras can be used to extract images of the transmission belt more comprehensively. An X-ray device can also be included, positioned at the bend of the transmission belt at the first pulley 32331 or the second pulley 32332, to capture images of the cross-section of the transmission belt 5, determining the presence of air bubbles and the varying heights of the ropes within the transmission belt 5.

[0090] In order to better focus and position the camera, thereby better extracting the image of the bottom surface of the transmission belt 5, the camera used to photograph the bottom surface of the transmission belt is preferably located directly below the gap formed by the first transmission pulley 32331 and the second transmission pulley 32332.

[0091] Four cameras are set up as a first camera 3221, a second camera 3222, a third camera 3223, and a fourth camera 3224. The first camera 3221 and the second camera 3222 are horizontally opposite each other, facing the two sides of the transmission belt 5 respectively. The third camera 3223 and the fourth camera 3224 are vertically opposite each other. The third camera 3223 is located above the transmission belt 5 and faces the back of the transmission belt 5. The fourth camera 3224 is located directly below the gap formed by the first transmission pulley 32331 and the second transmission pulley 32332 to photograph the bottom surface of the transmission belt 5.

[0092] Please see Figures 13-16The conveying assembly 41 includes a conveying bracket 411, a first drive member 412, a linkage assembly 413, a second drive member 414, and a conveying member 415. The conveying bracket 411 is mounted on the picking bracket 21 and provides support for the first drive member 412, the linkage assembly 413, the second drive member 414, and the conveying member 415. One end of the first drive member 412 is hinged to the conveying bracket 411. The linkage assembly 413 includes a fixed rod 4131, an input rod 4132, a connecting rod 4133, and an output rod 4134. The fixed rod 4131 is fixedly connected to the transport bracket 411. One end of the input rod 4132 is hinged to the fixed rod 4131, and one end of the input rod 4132 extends outward from the fixed rod 4131 to form an input portion 41321. The input portion 41321 is hinged to the other end of the first driving member 412. The connecting rod 4133 is parallel to the input rod 4132, and one end of the connecting rod 4133 is hinged to the fixed rod 4131. The other ends of the input rod 4132 and the other ends of the connecting rod 4133 are both hinged to the output rod 4134. One end of the second driving member 414 is hinged to the output rod 4134. The first end 4151 of the transport member 415 is hinged to the other end of the second drive member 414, and the transport member 415 is hinged to the output rod 4134 near the first end 4151, so that the second end 4152 of the transport member 415 can tilt downward or tilt upward around the hinge point 4153 near the first end 4151 under the action of the second drive member 414.

[0093] In order to facilitate the movement of the transport component 415 to the vicinity of the detection component 32 and to receive the transmission belt transmitted by the detection component 32 under the cooperation of the first drive component 412, the connecting rod assembly 413 and the second drive component 414, it is preferable that the swing axis of the input rod 4132 intersects with the swing axis of the transport component 415.

[0094] In order to better realize the movement of the second driving member 414 driving the transport member 415 around the hinge point 4153, it is preferable that the second driving member 414 extends in the vertical direction.

[0095] Please see Figure 13 The output rod 4134 includes an output rod body 41341 and a support plate 41342 connected to one side of the output rod body 41341. The other end of the input rod 4132 and the other end of the connecting rod 4133 are both hinged to the output rod body 41341. One end of the second driving member 414 and the transport member 415 near the first end 4151 are respectively hinged to the upper part of the support plate 41342 and the lower part of the support plate 41342.

Each transport rod 4155 includes a first rod body 41551 and a second rod body 41552. The first rod body 41551 is horizontally and vertically connected to the transport frame 4154, and the second rod body 41552 is set at an obtuse angle to the first rod body 41551, with the second rod body 41551 inclined upwards. At this time, the transport frame 4154 is hinged to the lower part of the support plate 41342, and the transport rods 4155 can quickly catch the transmission belt and quickly release it for storage.

[0097] Please see Figure 14 , Figure 15 The support plate 41342 includes a support plate body 413421, a first protrusion 413422 and a second protrusion 413423 extending outward along the upper and lower ends of the support plate body 413421 respectively, one end of the second drive member 414 is hinged to the first protrusion 413422, the second protrusion 413423 is inclined downward, and the transport frame 4154 is hinged to the second protrusion 413423 near the first end 4151.

[0098] Please see Figure 13 , Figure 14 The transport frame 4154 includes a first substrate 41541 parallel to the output rod 41341, a second substrate 41542 perpendicular to the first substrate 41541 and extending in a direction away from the transport rod 4155, and at least one third substrate 41543 connected to the second substrate 41542. The third substrate 41543 is perpendicular to the first substrate 41541 and the second substrate 41542. The two transport rods 4155 are respectively connected to the two ends of the same side of the first substrate 41541. The free end of the second substrate 41542 is hinged to the other end of the second drive member 414, and the third substrate 41543 is hinged to the second protrusion 413423. At this time, the third substrate 41543 and the second protrusion 413423 form a hinge point 4153. Preferably, there are two third substrates 41543, and the second bump 413423 is partially located between the two third substrates 41543, which improves the stability of the hinge between the third substrate 41543 and the second bump 413423 and improves the flexibility of the third substrate 41543 to rotate around the hinge point 4153.

[0099] The second driving member 414 includes a second driving cylinder 4141. The fixed end of the second driving cylinder 4141 is hinged to the output rod 4134, and the driving end of the second driving cylinder 4141 is hinged to the first end 4151 of the conveying member 415. Specifically, the fixed end of the second driving cylinder 4141 is hinged to the first protrusion 413422 of the support plate 41342, and the driving end of the second driving cylinder 4141 is hinged to the free end of the second substrate 41542.

[0100] In this embodiment, the first driving member 412 includes a first driving cylinder 4121. The fixed end of the first driving cylinder 4121 is connected to a receiving seat 4122. The receiving seat 4122 is hinged to the transport bracket 411. The driving end of the first driving cylinder 4121 is hinged to the input part 41321.

[0101] The fixed rod 4131 includes two fixed rod bodies 41311 arranged in parallel. Both fixed rod bodies 41311 extend out of the transport bracket 411. One end of the input rod 4132 and one end of the connecting rod 4133 are hinged to the two fixed rod bodies 41311 and located between the two fixed rod bodies 41311.

[0102] Please see Figure 13 , Figure 14 The transport bracket 411 includes a receiving plate 4111 and a mounting plate 4112 that is vertically connected to and extends from the receiving plate 4111. A rib 4113 connects the receiving plate 4111 and the mounting plate 4112. The mounting plate 4112 extends vertically, and one end of two fixing rods 41311 are respectively connected to the two sides of the mounting plate 4112, while the other end of the two fixing rods 41311 extends out of the mounting plate 4112.

[0103] The preferred material picking seat 231 is provided with two picking components 232 arranged side by side at intervals, the inspection frame 31 is provided with two inspection components 32, and the number of transport components 41 is two. Each picking component 232 can move under the drive of the horizontal drive mechanism 22 to grab the transmission belt 5 on the material frame 12 and transfer the transmission belt 5 to the corresponding inspection component 32. The corresponding transport component 41 transfers the qualified transmission belt after being inspected by the inspection component 32 to the qualified position.

[0104] A horizontal drive mechanism 22 can drive two picking components 232 to pick up materials alternately from the material rack 12. The two picking components 232 correspond to two detection components 32 respectively. That is, each picking component 232 can move to the corresponding detection component 32 or material rack 12 under the drive of the horizontal drive mechanism 2. On the one hand, it simplifies the structure, and on the other hand, it improves the utilization rate of the mechanism, picking efficiency and detection efficiency. At the same time, each conveying component 41 can transfer the qualified transmission belt after detection by the corresponding detection component 32 to the qualified position, with high transfer efficiency.

[0105] In order to store the qualified transmission belts after testing, it is preferable that the testing rack 31 is provided with qualified product racks 61 on both sides to store the qualified transmission belts after testing by the two testing components 2 respectively. At this time, the qualified position is the qualified product rack 61.

[0106] To facilitate the acquisition and storage of defective transmission belts after inspection by inspection component 32, please refer to Figure 17The sorting mechanism also includes a defective product acquisition mechanism 62, located on the side of the inspection rack 31 near the material rack 12. The defective product acquisition mechanism 62 transfers the defective conveyor belts inspected by the inspection component 32 to a defective product box 63, which is located inside the inspection rack 31. The defective product box 63 has an opening on the side closest to the defective product acquisition mechanism 62, facilitating the transfer of defective conveyor belts. A door 631 is located on the side of the defective product box 63 furthest from the defective product acquisition mechanism 62. (See also...) Figure 10 This facilitates the removal of defective conveyor belts from the defective product box 63 without affecting the inspection process. Preferably, the defective product acquisition mechanism 62 includes a first support frame 621, two first waste material acquisition drive cylinders 622 fixed to the first support frame 621, and two second support frames 623 respectively connected to the two first waste material acquisition drive cylinders 622. Each second support frame 623 is fixed with a second waste material acquisition drive cylinder 624 and a waste material acquisition claw 625. Each waste material acquisition claw 625 is provided with a waste material pushing plate 626. The drive end of the second waste material acquisition drive cylinder 624 is fixedly connected to the waste material pushing plate 626. The first support frame 621 is fixedly connected to the defective product box 63, and the two first waste material acquisition drive cylinders 622 are driven horizontally but in opposite directions. When the detection device 3 detects that the transmission belt 5 is defective, the first waste acquisition drive cylinder 622 drives the second support frame 623 to move horizontally, so that the waste acquisition claw 625 faces the transmission belt of the detection component 32. The detection component 32 pushes out the defective transmission belt, the waste acquisition claw 625 catches the defective transmission belt, the first waste acquisition drive cylinder 622 returns to its original position, and the second waste acquisition drive cylinder 624 drives the waste pusher plate 626 to push the defective transmission belt into the defective product box 63.

[0107] When this utility model is in use, the first drive motor 12311 starts, driving the drive pulley 12313 to rotate. The drive pulley 12313 drives the first synchronous belt 12312 to move, thereby driving the slider 1215 and the pusher 1232 on the slider 1215 to move. The pusher 1232 pushes multiple transmission belts 5 to move along the two material carriers 1212. The transmission belt 5 that is closest to the front in the direction of movement falls onto the two transfer brackets 1221 to wait for the material picking robot 2 to grab it. The pressing cylinder 1242 drives the pressing rod 1243 to press on the remaining multiple transmission belts 5 on the two material carriers 1212. After the multiple drive belts 5 on the material rack 12 at the loading position 15 have been pushed and loaded by the pusher 1232, the motor 1121 starts, driving the turntable body 111 to rotate through the reducer 1122, divider 1123, and disc 1124, thus rotating the material rack 12, which is full of drive belts 5 on the waiting position 14, to the loading position 15. The operator then loads the drive belts 5 onto the empty material rack 12 at the preparation position 13.

[0108] Two material handling components 232 are designated as the first material handling component and the second material handling component, respectively. Two detection components 32 are designated as the first detection component and the second detection component, respectively. The material rack 12 of the loading position 15 is located on the vertical line between the two detection components 32. Initially, the first material handling component faces the material rack 12, and the second material handling component faces the second detection component. Movement toward the material rack 12 is defined as backward movement, and movement away from the material rack 12 is defined as forward movement. Movement perpendicular to the direction of forward or backward movement is defined as leftward movement and rightward movement, respectively. The second horizontal moving mechanism 222 drives the material picking mechanism 23 to move backward toward the material rack 12. The gripper drive 23231 of the first material picking component is activated, and the two grippers 23232 clamp the transmission belt 5 to be tested on the material rack 12. At the same time, the two support rods 23241 on both sides of the material picking component 2323 pass through the transmission belt 5 and support the transmission belt 5. The first material picking component completes the material picking. The first horizontal moving mechanism 221 drives the second horizontal moving mechanism 222 and the material picking mechanism 23 on it to move to the right. At the same time, the rotation of the first material picking component... The drive unit 2321 is activated, causing the carrier unit 2322 and the material handling unit 2323 to rotate horizontally by 180°. The second horizontal moving mechanism 222 drives the material handling mechanism 23 to move forward towards the first detection component. The push-pull cylinder 23243 of the first material handling component is activated, pushing the push plate 23242 to push the transmission belt 5 to the first detection component. The first detection component detects the transmission belt. At the same time, the second material handling component of the material handling mechanism 23 rotates horizontally, so that the second material handling component faces the material rack 12. The second horizontal moving mechanism 222 drives... The material handling mechanism 23 moves backward, and the two grippers 23232 of the second material handling component clamp the transmission belt 5 to be tested on the material rack 12. At the same time, the two support rods 23241 on both sides of the material handling component 2323 pass through the transmission belt 5 and support the transmission belt 5. The second material handling component completes the material handling. The first horizontal moving mechanism 221 drives the second horizontal moving mechanism 222 and the material handling mechanism 23 on it to move to the left. At the same time, the rotation drive component 2321 of the second material handling component starts, driving the bearing component 2322 and the material handling component 2323 to rotate horizontally together. 180°; The second horizontal moving mechanism 222 drives the material picking mechanism 23 to move forward and face the second detection component. The push-pull cylinder 23243 of the second material picking component is activated, pushing the push plate 23242 to push the transmission belt 5 to the second detection component. The second detection component detects the transmission belt 5. At the same time, the rotation drive component 2321 of the first material picking component is activated, driving the bearing component 2322 and the material picking component 2323 to rotate horizontally by 180° together. The first material picking component faces the material frame 12 and repeats the above movements to realize the alternating picking of the transmission belt 5.

[0109] When the material handling component 232 grips the transmission belt 5 to be inspected and places it onto the corresponding inspection component 32, the transmission belt 5 is wrapped around the first transmission pulley 32331, the second transmission pulley 32332 and the third transmission pulley 32333. The upper side of the transmission belt 5 is hung on the first transmission pulley 32331 and the second transmission pulley 32332. The first rotary cylinder 32512 drives the first limit wheel 32511 to rotate and the second rotary cylinder 32522 drives the second limit wheel 32521 to rotate and press them onto the transmission belt 5 respectively. The linear drive unit 3262 drives the third transmission pulley 32333 to adjust the position of the third transmission pulley 32333 in the vertical direction, so that the transmission belt is tensioned on the first transmission pulley 32331, the second transmission pulley 32332 and the third transmission pulley 32333.
