The automatic detection device mainly includes a feeding device, a detection device, and a handling device. There are several feeding devices, which are respectively arranged at the loading station and the unloading station. The handling device is connected between the feeding device and the detection device. The feeding device at the loading station is used to provide a tray loaded with products to be detected. The handling device can transport the products in the tray to the detection device for detection. The feeding device at the unloading station is used to provide empty trays to receive the detected products transported by the handling device.

[0003] The feeding device generally includes a transmission line, a stack of mechanisms respectively arranged at both ends of the transmission line, and a positioning mechanism arranged in the middle of the transmission line. One of the stack mechanisms can separate the trays one by one onto the transmission line, and the other stack mechanism can stack the trays on the transmission line one by one. The positioning mechanism is used to position the trays for the handling device to pick up or place materials. The transmission line is adapted to drive the trays to be sequentially transported from one of the stack mechanisms to the positioning mechanism and the other stack mechanism.

[0004] However, for the feeding device with the above structure, the transmission of the trays completely depends on the transmission line, resulting in low transmission efficiency, and thus affecting the working efficiency of the feeding device.

Detailed implementation manners

[0057] To make the above objects, features, and advantages of the present application more apparent and understandable, the following provides a detailed description of the specific embodiments of the present application in conjunction with the accompanying drawings. It can be understood that the specific embodiments described herein are only for explaining the present application and are not intended to limit the present application. Additionally, it should be noted that for ease of description, only the parts related to the present application rather than all the structures are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0058] The terms "including" and "having" in this application, as well as any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0059] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments can be included in at least one embodiment of the present application. The phrase appearing in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0060] Please refer to Figure 1 and Figure 2 As shown, corresponding to a preferred embodiment of the present invention, the feeding device 1000 includes: a transmission line 100, along which a loading position, a feeding position, and an unloading position are arranged in sequence; a tray receiving mechanism 200, including a translation module 210, a lifting module 220 provided on the translation module 210, and a tray receiving component 230 provided on the lifting module 220; a first stacking mechanism 300 provided at the loading position; a second stacking mechanism 400 provided at the unloading position; wherein, the tray receiving component 230 is adapted to lift and fix the tray on the transmission line 100 under the drive of the lifting module 220, and the translation module 210 is adapted to drive the tray receiving component 230 to move towards the first stacking mechanism 300 or the second stacking mechanism 400.

[0061] In order to ensure the smooth transmission of the transmission line 100, the transmission speed of the transmission line 100 is usually set to be slow. The present invention sets a receiving tray mechanism 200. When the transmission line 100 transports the material tray released from the first stacking mechanism 300 to the feeding position, the translation module 210 can drive the receiving tray assembly 230 to move toward the material tray, and receive and fix the material tray under the lifting of the lifting module 220, and then transfer it to the feeding position. When the product in the material tray at the feeding position is transferred, the translation module 210 can drive the material tray to move to the second stacking mechanism 400, thereby improving the transmission efficiency of the material tray.

[0062] Further, refer to Figures 2 to 4 As shown, the transmission line 100 includes a base frame 110 and a conveyor belt 120. The base frame 110 includes two profile frames 111 arranged in parallel. The arrangement direction of the two profile frames 111 is the width direction of the transmission line 100. Each profile frame 111 is provided with a conveyor belt 120. The two conveyor belts 120 are suitable for carrying and conveying material trays. A first adjustment structure 112 is provided between the two profile frames 111. The two profile frames 111 adjust their positions along the width direction of the transmission line 100 in response to the action of the first adjustment structure 112 to adapt to material trays of different sizes. The first adjustment structure 112 can specifically use a motor and a screw to adjust the distance between the two profile frames 111. It is a well-known structure and the present invention will not be repeated here.

[0063] Furthermore, the receiving plate mechanism 200 is located between the two profile frames 111. The translation module 210 is a linear module arranged along the length direction of the transmission line 100, and the lifting module 220 is a screw lift, which is not described in detail in the present invention. The receiving plate assembly 230 includes a base plate 231, a supporting plate 232, a clamping unit 233 and a clamping module 234. The base plate 231 is connected to the lifting module 220, and the supporting plate 232 is used to support the material tray. The supporting plate 232 is fixed above the base plate 231 by a support column 235 so that an installation space is formed between the supporting plate 232 and the base plate 231. The supporting plate 232 is provided with an avoidance structure 2321 in the vertical direction, and the avoidance structure 2321 extends from the middle of the supporting plate 232 to the side of the supporting plate 232 along the length direction of the transmission line 100. The clamping unit 233 can be slidably disposed on the base plate 231 along the length direction of the base plate 231, and a portion of the clamping unit 233 extends out of the bearing surface of the bearing plate 232 through the avoidance structure 2321. The clamping module 234 is disposed on the base plate 231, and is in transmission connection with the clamping unit 233. In this embodiment, the avoidance structure 2321 is in two groups, and is disposed on both sides of the bearing plate 232 in the length direction of the transmission line 100. The clamping units 233 correspond to the avoidance structures 2321 one by one, and the two groups of clamping units 233 are suitable for moving toward each other under the drive of the clamping module 234 to clamp the material tray, or moving away from each other to release the material tray.

[0064] By providing the avoidance structure 2321, the present invention can make the size of the carrier plate 232 in the length direction of the transmission line 100 larger while avoiding hindering the movement of the clamping unit 233, thereby making it easier to receive the tray, and the stability and reliability of the tray on the carrier plate 232 are better.

[0065] Specifically, the clamping unit 233 includes a bracket 2331 and a clamping member 2332. A slide rail structure is provided between the bracket 2331 and the substrate 231 so that the bracket 2331 is slidably disposed on the substrate 231. The clamping member 2332 is placed on the bearing surface of the carrier plate 232, and a part of it extends into the corresponding avoidance structure 2321 and is fixedly connected to the bracket 2331. Preferably, the clamping member 2332 is a strip-shaped block extending towards both sides of the carrier plate 232 along the width direction of the transmission line 100 to improve the stability of the tray after clamping. Each avoidance structure 2321 includes two avoidance holes 2322 arranged side by side. The length direction of the avoidance holes 2322 is parallel to the length direction of the transmission line 100. The two ends of the clamping member 2332 correspond to the two avoidance holes 2322 one by one. Connecting portions 2333 are provided at both ends of the clamping member 2332 and are inserted into the avoidance holes 2322. The connecting portions 2333 can slide along the length direction of the avoidance holes 2322, and the connecting portions 2333 are fixed to the bracket 2331. Preferably, the clamping member 2332 is an L-shaped block, and an embedding groove 236 is formed between it and the carrier plate 232. The side of the tray can be embedded into the embedding groove 236 to limit the tray in the vertical direction and improve the stability during the clamping process.

[0066] The clamping module 234 can specifically be driven by a motor cooperating with a transmission belt group. The transmission belt group includes two parallel belt portions. The two brackets 2331 are respectively fixed to different belt portions. The clamping module 234 is a conventional driving structure, which will not be elaborated in the present invention.

[0067] Furthermore, the process of the tray receiving mechanism 200 of the present invention for receiving a tray is as follows: The translation module 210 drives the tray receiving assembly 230 to move to directly below the tray, and then the lifting module 220 drives the tray receiving assembly 230 to rise and lift the tray off the conveyor belt 120. Then, the two clamping members 2332 move towards each other under the drive of the clamping module 234 to clamp the tray.

[0068] However, for the tray receiving mechanism 200 with the above structure, after the tray is clamped by the tray receiving mechanism 200, the position accuracy of the tray in the width direction of the transmission line 100 is poor. Preferably, a positioning mechanism 130 is provided at the feeding position of the transmission line 100. The positioning mechanism 130 is adapted to position the tray on the tray receiving assembly 230 along the width direction of the transmission line 100, improving the position accuracy of the tray at the feeding position and facilitating the subsequent transfer of products.

[0069] The positioning mechanism 130 includes a movable positioning block 131, a positioning cylinder 132, and a fixed positioning block 133. The movable positioning block 131 and the fixed positioning block 133 are respectively arranged on different profile frames 111 and are oppositely arranged. The positioning cylinder 132 is connected between one of the profile frames 111 and the movable positioning block 131. The movable positioning block 131 is adapted to move along the width direction of the transmission line 100 under the drive of the positioning cylinder 132 to push the tray against the fixed positioning block 133, so as to realize the positioning of the tray in the width direction of the transmission line 100.

[0070] Further, the first stacking mechanism 300 includes a first frame 310, a first stacking module 320, and a plurality of material separating components 330. The first frame 310 includes a first limiting post 311 and a second limiting post 312 that are sequentially arranged on the transmission line 100 along the transmission direction of the transmission line 100. The first limiting post 311 and the second limiting post 312 extend along the vertical direction. The transmission direction of the transmission line 100 is specifically the direction from the first stacking mechanism 300 to the second stacking mechanism 400. In this embodiment, each profile frame 111 is provided with a first limiting post 311 and a second limiting post 312. The first limiting posts 311 on both sides are oppositely arranged, and the second limiting posts 312 on both sides are oppositely arranged. The first limiting post 311 and the second limiting post 312 cooperate to enclose a receiving space for receiving stacked trays. The first limiting post 311 and the second limiting post 312 are both L-shaped posts to limit the tray in both the length direction and the width direction of the transmission line 100. The bottom of the first frame 310 is provided with a flow outlet, and the tray can flow from the bottom of the first frame 310 to the transmission line 100. The transmission line 100 is adapted to drive the tray to flow out from the flow outlet for transmission to the feeding position.

[0071] The first stacking module 320 is located below the first frame 310 and is adapted to extend upward into the first frame 310 to receive the tray and place the tray downward on the conveyor belt 120. The structure of the first stacking module 320 is similar to the structure of the lifting module 220. It is located directly below the first frame 310, and details are not described herein in the present invention.

[0072] A plurality of material separating components 330 are respectively arranged on both sides of the first frame 310 in the width direction of the transmission line 100 for separating out single trays. In this embodiment, two sets of material separating components 330 are provided on each profile frame 111, and both sets of material separating components 330 are located between the first limiting post 311 and the second limiting post 312. Refer to Figure 4 as shown in Figure 5As shown, the material distribution assembly 330 includes a first material distribution cylinder 331, a support block 332, a second material distribution cylinder 333 and a lower pressing block 334. The support block 332 is slidably arranged on the profile frame 111 through a slide rail structure, and the first material distribution cylinder 331 is arranged on the profile frame 111 and is transmission-connected with the support block 332. The first material distribution cylinder 331 is a linear cylinder arranged along the width direction of the transmission line 100. The support block 332 can extend into the first frame 310 along the width direction of the transmission line 100 under the drive of the first material distribution cylinder 331 to support the material tray in the first frame 310. The second material distribution cylinder 333 is arranged on the support block 332, and is transmission-connected with the lower pressing block 334. The second material separation cylinder 333 is a linear cylinder arranged along the vertical direction, which is suitable for driving the lower pressing block 334 to move downward to push the material tray supported below the upper material tray of the support block 332 downward to facilitate the separation of the material tray.

[0073] Preferably, a second adjustment structure 340 is provided between the first limiting column 311 and the base frame 110, and the first limiting column 311 moves along the width direction of the transmission line 100 in response to the action of the second adjustment structure 340. By adopting the above structure, when the material tray is loaded on the first frame 310, the material tray does not need to be placed from the top of the first frame 310, but only needs to use the second adjustment structure 340 to make the two opposite first limiting columns 311 move away from each other along the width direction of the transmission line 100, so that the first frame 310 can form an entrance for the material tray to enter the first frame 310 on one side of the length direction of the transmission line 100, and the operator only needs to push the stacked material tray into the conveyor belt 120 from the feeding end of the transmission line 100, and then the conveyor belt 120 can transfer the material tray to the first frame 310. The second adjustment structure 340 is specifically a linear cylinder arranged along the width direction of the transmission line 100, which is transmission-connected with the first limiting column 311 to drive the first limiting column 311 to move. Since the tray receiving mechanism 200 is provided, when the first stacking mechanism 300 performs a material replenishment operation, the tray receiving mechanism 200 can lift the material tray on the transmission line 100 to prevent it from being affected by the conveyor belt 120, thereby preventing it from affecting normal operation and realizing non-stop material replenishment operation.

[0074] Preferably, a third adjustment structure 350 is provided between the second limiting column 312, the material distribution assembly 330 and the base frame 110, and the second limiting column 312 and the material distribution assembly 330 move along the length direction of the transmission line 100 in response to the action of the third adjustment structure 350. By adopting the above structure, the first frame 310 can adjust the size along the length direction of the transmission line 100 to adapt to material trays of different sizes, thereby improving versatility.

[0075] The third adjustment structure 350 includes an adjustment frame 351, an adjustment rod 352, and a sliding seat 353. The adjustment frame 351 is fixed to the profile frame 111. The adjustment rod 352 is fixed to the adjustment frame 351 and is arranged along the length direction of the transmission line 100. The sliding seat 353 is slidably sleeved on the adjustment frame 351. There are multiple sliding seats 353, which respectively correspond to the material distribution components 330 and the second limit posts 312 one by one. Combining Figure 5 As shown, the sliding seat 353 is provided with a connection hole 3531 adapted to the adjustment rod 352. The inner wall of the connection hole 3531 is provided with a notch 3532, and the notch 3532 extends along the radial direction of the connection hole 3531 to one side of the sliding seat 353. A locking member 354 is threadedly connected to the sliding seat 353. The locking member 354 is located at the notch 3532. When the locking member 354 is tightened, it can accommodate the notch 3532, thereby fastening the sliding seat 353 to the adjustment rod 352. When the locking member 354 is loosened, it can expand the notch 3532 so that the sliding seat 353 can slide along the adjustment rod 352.

[0076] Furthermore, the second stacking mechanism 400 includes a second frame body 410, a second stacking module 420, and several support components 430. The second frame body 410 includes a third limit post 411 and a fourth limit post 412 that are sequentially arranged on the base frame 110 along the transmission direction of the conveyor belt 120. The third limit post 411 and the fourth limit post 412 extend along the vertical direction. Each profile frame 111 is provided with a third limit post 411 and a fourth limit post 412. The third limit posts 411 on both sides are arranged oppositely, and the fourth limit posts 412 on both sides are arranged oppositely. The third limit post 411 and the fourth limit post 412 cooperate to enclose a receiving space for receiving the stacked trays. The third limit post 411 and the fourth limit post 412 are adapted to limit the trays bidirectionally in the width direction of the transmission line 100. The bottom of the second frame body 410 is provided with an inlet, and the trays on the conveyor belt 120 can flow into the second frame body 410 through the inlet. Preferably, only the third limit post 411 is an L-shaped post, which is adapted to block the trays in the direction opposite to the transmission direction of the conveyor belt 120 and allow the trays to flow out of the second frame body 410 along the transmission direction of the conveyor belt 120. By adopting the above structure, when the second stacking mechanism 400 is full of stacked trays, the operator can directly remove the trays from one side of the second frame body 410 in the length direction of the transmission line 100, without having to take the trays from above the second frame body 410, which is more convenient to operate and effectively simplifies the structure of the second stacking mechanism 400.

[0077] The second stack module 420 is located below the second housing 410 and is adapted to lift the tray into the second housing 410. A plurality of support components 430 are disposed on both sides of the transfer line 100 in the width direction and are used to support the tray in the second housing 410. The support component 430 is configured to allow the tray to enter the second housing 410 unidirectionally upward. Preferably, a material blocking mechanism 140 is further provided on the transfer line 100. The number of the material blocking mechanisms 140 is several, and they are respectively located at the discharge side of the first stacking mechanism 100, the feeding side and the discharge side of the second stacking mechanism 300. The material blocking mechanism 140 is adapted to rise and block the tray transported on the conveyor belt 120. The material blocking mechanism 140 may specifically be composed of a cylinder and a material blocking block, which is a well-known structure and will not be elaborated herein in the present invention.

[0078] In this embodiment, at least one set of support components 430 are spaced along the length direction on each side of the transfer line 100. The fourth limit post 412 is disposed on the support component 430 and corresponds to the support component 430 one by one. Refer to Figure 6 and Figure 7 As shown, the support component 430 includes a mounting seat 431, a flipping block 432 and a first elastic member 433. The mounting seat 431 is disposed on the transfer line 100. The flipping block 432 is rotatably disposed on the mounting seat 431 and partially extends into the second housing 410. The first elastic member 433 is a spring, which is connected between the flipping block 432 and the mounting seat 431. When the tray is moved upward into the second housing 410, the flipping block 432 is adapted to flip upward to avoid the tray and compress the first elastic member 433. And when the tray moves above the flipping block 432, the flipping block 432 is adapted to reset under the resilience of the first elastic member 433 and support the tray. By adopting the above structure, the support component 430 has a simple structure. During the material receiving process, without the intervention of a driving member, the cost is effectively reduced.

[0079] However, with the above structure, when an operator drags the tray on the flipping block 432 for blanking, since the support components 430 are arranged at intervals along the length direction of the transfer line 100, it is difficult for the flipping block 432 to completely cover the tray. During the dragging process, the tray is likely to fall into the gap between adjacent flipping blocks 432. Therefore, the operator needs to support the bottom of the tray, resulting in very inconvenient blanking.

[0080] Preferably, the support assembly 430 further includes a flip cylinder 434 disposed on the mounting seat 431. The flip cylinder 434 is a linear cylinder arranged in the vertical direction, and its output end is arranged downward. The output end of the flip cylinder 434 is suitable for approaching and pushing the flip block 432 to flip the flip block 432 upward. The flip cylinder 434 and the second stacking module 420 cooperate with each other to make the stacked material trays fall from the second frame 410 to the conveyor belt 120. The conveyor belt 120 is suitable for driving the material trays to flow out of the second frame 410 along the transmission direction, so that the material trays can be unloaded smoothly and reliably without manual dragging. In addition, when the second stacking mechanism 400 performs normal material collection operations, the output end of the flip cylinder 434 can be retracted upward to stay away from the flip block 432, so that the normal flipping of the flip block 432 will not be affected by the flip cylinder 434.

[0081] Since the second stacking mechanism 400 is used for collecting and stacking, the second stacking module 420 does not need to adopt a lifting structure like the first stacking module 320, but only needs to realize two-stage movement by pneumatic means. The second stacking module 420 includes a lifting cylinder 421 and a lifting block 422 that is transmission-connected to the lifting cylinder 421. The lifting cylinder 421 is a linear cylinder arranged along the vertical direction. The lifting block 422 is suitable for lifting the material tray upward under the drive of the lifting cylinder 421, or resetting downward to below the bearing surface of the transmission line 100. Preferably, the number of the second stacking modules 420 is two groups, and they are respectively arranged on the inner side surfaces opposite to the two second profile frames 111, and the two groups of second stacking modules 420 cooperate to lift the material tray.

[0082] Further, two groups of support components 430 are provided on each side of the transmission line 100, one of the support components 430 on each side of the transmission line 100 is arranged adjacent to the third limiting column 411, and the other support component 430 is provided at the discharge end of the transmission line 100, and a fourth adjustment structure 440 is provided between the third limiting column 411, the support component 430 adjacent to the third limiting column 411, and the transmission line 100, and the third limiting column 411 and the support component 430 adjacent to the third limiting column 411 move along the length direction of the transmission line 100 in response to the action of the fourth adjustment structure 440. The structure of the fourth adjustment structure 440 is similar to that of the third adjustment structure 350, and the present invention will not be described in detail herein.

[0083] By adopting the above structure, the second stacking mechanism 400 can be greatly simplified while ensuring that the material tray is stably and reliably accommodated in the second frame 410; in addition, the size of the second frame 410 in the length direction of the transmission line 100 can be adjusted according to actual needs to adapt to material trays of different sizes, thereby improving versatility.

[0084] The working process of the feeding device 1000 of the present invention is as follows: The second adjustment structure 340 drives the corresponding first limit posts 311 to move away from each other in the width direction of the transmission line 100 to form a tray inlet. An operator pushes a stack of trays containing products to be detected from the inlet end of the transmission line 100 onto the conveyor belt 120. The conveyor belt 120 drives the trays to move into the first frame 310 from the tray inlet. Then the first limit posts 311 reset, and the trays are limited in the first frame 310. Next, the first stacking module 320 jacks up the trays and positions the lowermost tray above the material distribution component 330. Then the material distribution component 330 extends into the first frame 310, and the first stacking module 320 descends, and the trays are carried on the material distribution component 330;

[0085] When it is necessary to convey a tray to the feeding position, the material distribution component 330 and the first stacking module 320 cooperate with each other to lower a single tray onto the conveyor belt 120. The conveyor belt 120 drives the tray to move towards the feeding position. During this process, the tray receiving mechanism 200 moves towards the first stacking mechanism 300, jacks up and clamps the tray, and then takes over the conveyor belt 120 to move it to the feeding position. The positioning mechanism 130 at the feeding position can push the tray in the width direction of the transmission line 100 to achieve precise positioning of the tray, facilitating the picking of products in the tray;

[0086] After the products in the tray are picked, the positioning mechanism 130 releases the tray. The tray receiving mechanism 200 drives the tray to move a certain distance towards the second stacking mechanism 400 and then places the tray back on the conveyor belt 120. The conveyor belt 120 can drive the tray to move to directly below the second frame 410. The second stacking module 420 can jack up the tray into the second frame 410 so that the flipping block 432 carries the tray. During this process, the first stacking mechanism 300 can continue to lower the tray, and the tray receiving mechanism 200 moves back towards the first stacking mechanism 300 and repeats the previous actions;

[0087] When the second frame 410 is full of trays, the second stacking module 420 jacks up the tray to keep a certain distance between the tray and the flipping block 432. Then the flipping cylinder 434 pushes the flipping block 432 downward to make it flip upward. Then the second stacking module 420 descends to place the tray on the conveyor belt 120. The conveyor belt 120 transports the tray towards the discharge end of the transmission line 100 for the operator to remove the tray.

[0088] Further, referring to Figure 1 、 Figure 8 and Figure 9As shown, the feeding device 1000 also includes a conveying mechanism 500 located above the transmission line 100, and the conveying mechanism 500 is suitable for conveying the products in the material tray at the feeding position. The conveying mechanism 500 includes a conveying module 510, a mounting frame 520, a first lifting module 530 and a pick-and-place assembly 540. The mounting frame 520 is arranged on the conveying module 510, and the conveying module 510 is a linear module, which is suitable for driving the mounting frame 520 to move along the length direction and width direction of the transmission line 100. The first lifting module 530 is arranged on the mounting frame 520, and is transmission-connected with the pick-and-place assembly 540 to drive the pick-and-place assembly 540 to rise and fall in the vertical direction. Preferably, there are multiple first lifting modules 530, and they are arranged side by side along the width direction of the transmission line 100. The pick-and-place assembly 540 corresponds to the first lifting module 530 one by one, and multiple pick-and-place assemblies 540 can simultaneously pick and place multiple products, thereby improving the pick-and-place efficiency. The first lifting module 530 may specifically use a synchronous belt and a motor to drive the pick-and-place assembly 540 , which is a well-known structure and will not be elaborated herein.

[0089] Furthermore, the pick-and-place assembly 540 includes a tube body 541, a quick-change joint 542 and a suction head 543 arranged along the vertical direction. The tube body 541 is connected to the first lifting module 530. The upper end of the tube body 541 is provided with an air joint 544 that is connected to the external vacuum generating structure. The quick-change joint 542 is connected between the lower end of the tube body 541 and the suction head 543. The quick-change joint 542 can realize the rapid disassembly, assembly and replacement of the suction head 543 to adapt to different types of products.

[0090] The quick-change connector 542 includes a quick-change seat 5421, a clamping member 5422, and a second elastic member 5423. The quick-change seat 5421 is penetrated along the vertical direction to form a plug hole 5424, and the tube body 541 is adapted to the plug hole 5424, and its lower end is plugged into the plug hole 5424. A lug 5425 is provided on the peripheral side of the quick-change seat 5421, and the clamping member 5422 is located outside the peripheral side of the quick-change seat 5421 and is rotatably connected to the lug 5425. The lower end of the clamping member 5422 protrudes relative to the bottom of the quick-change seat 5421, and extends toward the quick-change seat 5421 to form a hook 5426. The second elastic member 5423 is connected between the upper end of the clamping member 5422 and the quick-change seat 5421.

[0091] The suction head 543 includes a suction head base 5431, a docking member 5432, and a suction nozzle 5433. The outer contour of the docking member 5432 is circular, and a guide through-hole 5434 is axially formed through it. The upper end of the docking member 5432 is adapted to the insertion hole 5424, and it is inserted into the insertion hole 5424 from the bottom of the insertion hole 5424 so that the guide through-hole 5434 is communicated with the inner hole of the pipe body 541. The lower end of the docking member 5432 is in plug-in fit with the suction head base 5431 and is fixed to the suction head base 5431 through a threaded member. The suction nozzle 5433 is installed on the suction head base 5431. The number of suction nozzles 5433 is several and is arranged according to different actual products. The guide through-hole 5434 is communicated with the suction nozzle 5433 through the suction head base 5431 to provide negative pressure to the suction nozzle 5433.

[0092] A clamping groove 5435 is formed by the inward depression of the outer periphery of the docking member 5432. The clamping groove 5435 is formed in a circumferential ring along the docking member 5432. The clamping hook 5426 corresponds to the clamping groove 5435. The second elastic member 5423 is adapted to provide a force to turn the clamping hook 5426 towards the clamping groove 5435 to achieve the embedded fit between the clamping hook 5426 and the clamping groove 5435, thereby tightly connecting the docking member 5432 and the pipe body 541.

[0093] Preferably, the number of the clamping members 5422 is two and they are arranged oppositely. The second elastic members 5423 correspond to the clamping members 5422 one by one. The two clamping members 5422 are adapted to cooperate to clamp the docking member 5432 to improve the connection stability between the suction head 543 and the pipe body 541. When the suction head 543 needs to be replaced, only the upper end of the clamping member 5422 needs to be pressed to turn the clamping hook 5426 away from the clamping groove 5435, and the unlocking of the suction head 543 and the pipe body 541 can be achieved.

[0094] Further, referring to Figure 10 As shown, the present invention further provides an automatic detection system, including a machine table 2000 and a detection device 3000. The feeding device 1000 and the detection device 3000 are both arranged on the machine table 2000. The handling mechanism 500 is adapted to carry the product to the detection device 3000 to achieve the appearance detection of the product.

[0095] Further, referring to Figures 11 to 13As shown, the detection device 3000 is located on one side of the feeding device 1000 in the width direction of the transmission line 100, and includes a first transfer mechanism 600, a first detection mechanism 700, a second transfer mechanism 800, and a second detection mechanism 900 arranged in sequence. The first transfer mechanism 600 is suitable for receiving the product transported by the transport mechanism 500, and driving the product to flow to the first detection mechanism 700, and the first detection mechanism 700 is suitable for performing appearance inspection on the front and two side surfaces of the product, and then the second transfer mechanism 800 is suitable for receiving the product on the first transfer mechanism 600, and driving the product to flow to the second detection mechanism 900, and the second detection mechanism 900 is suitable for performing appearance inspection on the back and the other two side surfaces of the product.

[0096] Specifically, the first transfer mechanism 600 includes a first transfer platform 610 and a first transfer module 620, and the first transfer platform 610 is connected to the first transfer module 620 in a transmission manner. The table surface of the first transfer platform 610 is arranged upward, and a plurality of first carriers 630 are arranged side by side on the table surface of the first transfer platform 610, and the first carriers 630 correspond to the pick-and-place components 540 of the conveying mechanism 500 one by one. The first transfer module 620 is a linear module arranged along the width direction of the transmission line 100. When working, it can drive the first transfer platform 610 to move to one side of the transmission line 100, so that the conveying mechanism 500 places the product on the first carrier 630, and then the first transfer module 620 can drive the first transfer platform 610 to move to the first detection mechanism 700, so that the first detection mechanism 700 detects the product. The first carrier 630 is a vacuum adsorption structure and is suitable for adsorbing the back of the product. It is a well-known structure, and the present invention will not be described in detail here.

[0097] The first transfer module 620 is located below the first transfer platform 610, and the first transfer platform 610 is supported on the first transfer module 620. With the above structure, when the system is running, there is a probability that the product falls onto the first transfer module 620, thereby affecting the operation of the first transfer module 620. Preferably, in one embodiment, both ends of the first transfer module 620 are provided with mounting plates 640, and the outer cover of the first transfer module 620 is provided with an accordion cover 650, the number of the accordion covers 650 is two, and they can be extended and retracted along the driving direction of the first transfer module 620, one end of one accordion cover 650 is connected to one of the mounting plates 640, and the other end is connected to the first transfer platform 610, and one end of the other accordion cover 650 is connected to another mounting plate 640, and the other end is connected to the first transfer platform 610. When the first transfer module 620 drives the first transfer platform 610 to transfer, the accordion cover 650 can always cover the first transfer module 620 .

[0098] However, with the above structure, limited by the bellows cover 650, the first transfer table 610 has a relatively high height in the vertical direction, resulting in poor space adaptability and prone to causing the overall height of the machine to be too high. As a preferred embodiment, the first transfer module 620 is suspended below the platen of the machine table 2000 through a connecting frame. The platen of the machine table 2000 is provided with an avoidance opening penetrating in the vertical direction, and the avoidance opening extends along the transfer direction of the first transfer module 620. The first transfer table 610 is drivingly connected to the first transfer module 620 through the avoidance opening. The mounting plate 640 is arranged on the platen surface of the platen, and the bellows cover 650 is placed on the platen surface of the platen and covers the avoidance opening, so as to effectively reduce the height of the first transfer mechanism 600 above the platen of the machine table 2000 and improve the space adaptability.

[0099] Further, the structure of the second detection mechanism 900 is similar to that of the first detection mechanism 700, and the present invention will not elaborate here.

[0100] Further, the second transfer mechanism 800 includes a second transfer table 810, a second transfer module 820 and a second lifting module 830. The second lifting module 830 is arranged on the second transfer module 820, and the second transfer table 810 is drivingly connected to the second lifting module 830. The table surface of the second transfer table 810 is arranged downward, and a plurality of second carriers 840 are arranged side by side on the table surface of the second transfer table 810. The second carriers 840 correspond to the picking and placing components 540 one by one. The second transfer module 820 is a linear module arranged along the width direction of the transmission line 100. During operation, it can drive the second transfer table 810 to move towards the first transfer table 610, and under the drive of the second lifting module 830, approach the first transfer table 610, so that the second carriers 840 adsorb the front surface of the product, and then transfer the product to the second detection mechanism 900 for detection. The second carrier 840 is specifically an adsorption type carrier, and the present invention will not elaborate here.

[0101] Since the second detection mechanism 900 needs to detect the other two sides of the product, preferably, the second transfer mechanism 800 further includes a rotation module 850 arranged on the second transfer table 810. The rotation module 850 is drivingly connected to the second carrier 840 to drive the second carrier 840 to rotate 180° before transferring the product to the second detection mechanism 900, so that the other two sides of the product correspond to the second detection mechanism 900.

[0102] Furthermore, the automatic detection system further includes a transfer device 4000 and a blanking device 5000. The transfer device 4000 is arranged side by side on the side of the detection device 3000 away from the feeding device 1000. The second transfer mechanism 800 can transfer the detected products to the transfer device 4000, and the blanking device 5000 can receive the products on the transfer device 4000. The number of the blanking devices 5000 is preferably two, and they are respectively used to receive the qualified products and the unqualified products after detection. The structure of the blanking device 5000 is the same as that of the feeding device 1000, and will not be elaborated herein in the present invention.

[0103] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present application.
