Detailed implementation manners

[0071] To make the above objects, features, and advantages of the present application more apparent and understandable, the following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only for explaining the present application and not for limiting the present application. Additionally, it should be noted that for the convenience 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 belong to the scope of protection of the present application.

[0072] The terms "including" and "having" and any variations thereof in the present application 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.

[0073] Referring to the embodiments herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and 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.

[0074] Please refer to Figure 1 As shown, corresponding to a labeling device 1000 of a preferred embodiment of the present invention, it includes a labeling device 100, and the labeling device 100 includes: a blanking mechanism 110; a first handling mechanism 120 adapted to stack a preset number of trays 200 containing products on the blanking mechanism 110; a first feeding mechanism 130 accommodating a number of stacked and empty trays 200, and the first feeding mechanism 130 is adapted to feed the trays 200; a labeling mechanism 140 adapted to label the empty trays 200 fed out; wherein, whenever the blanking mechanism 110 receives a preset number of trays 200 containing products, the first handling mechanism 120 stacks a labeled empty tray 200 on the topmost tray 200 containing products.

[0075] The present invention adopts the above-mentioned structure, the first loading mechanism 130 can load the empty material tray 200, and the labeling mechanism 140 is used to label the empty material tray 200 that has been loaded. Whenever the first conveying mechanism 120 stacks a preset number of material trays 200 loaded with products and places them on the unloading mechanism 110, the first conveying mechanism 120 will stack an empty material tray 200 after labeling on the top layer of material tray 200 loaded with products. When the unloading mechanism 110 is fully loaded and unloads materials, the empty material tray 200 can block two adjacent groups of the preset number of material trays 200, which is convenient for the orderly and centralized storage of the material trays 200, and the preset number of material trays 200 can be quickly removed later, and the categories of products in the material tray 200 can be distinguished; in addition, because the labeling mechanism 140 only affixes labels on the empty material tray 200, the labeling efficiency is high, and the consumption of labels is effectively reduced, thereby reducing costs.

[0076] Furthermore, the labeling device 1000 further includes a machine platform 300 , and the unloading mechanism 110 , the first conveying mechanism 120 , the first loading mechanism 130 and the labeling mechanism 140 are all disposed on the machine platform 300 .

[0077] Furthermore, the products after the appearance inspection are divided into qualified products, unqualified products and critical products between qualified and unqualified. Accordingly, there are multiple unloading mechanisms 110, which are divided into a first unloading mechanism 110a, a second unloading mechanism 110b and a third unloading mechanism 110c. The first unloading mechanism 110a is used to accommodate the tray 200 containing qualified products transported by the first transport mechanism 120, the second unloading mechanism 110b is used to accommodate the tray 200 containing unqualified products transported by the first transport mechanism 120, and the third unloading mechanism 110c is used to accommodate the tray 200 containing critical products transported by the first transport mechanism 120.

[0078] In this embodiment, the specific number of the first unloading mechanism 110a, the second unloading mechanism 110b and the third unloading mechanism 110c is one respectively, in order to simplify the structure. Of course, in other embodiments, more can be set according to actual needs, and the present invention is not limited here. A plurality of unloading mechanisms 110 are arranged side by side along the first horizontal direction, and the first loading mechanism 130 and the labeling mechanism 140 are arranged side by side on one side of the unloading mechanism 110 on the outside, and the first loading mechanism 130 is located between the labeling mechanism 140 and the unloading mechanism 110. The labeling mechanism 140 is suitable for attaching one of qualified labels, unqualified labels and critical labels to the empty material tray 200, and the first transport mechanism 120 is suitable for transporting the unloaded material tray 200 after labeling to the corresponding unloading mechanism 110.

[0079] Further, refer to Figure 1 and Figure 2As shown, the material unloading mechanism 110 includes a material unloading frame 111, a supporting assembly 112 and a first material receiving assembly 113. The material unloading frame 111 is a through structure in the vertical direction, which is used to accommodate the stacked material trays 200. The top of the material unloading frame 111 is provided with a discharge port for placing the material trays 200. The material unloading frame 111 is composed of at least four L-shaped limiting plates 1111, which are arranged around the material trays 200 to horizontally limit the material trays 200. The supporting assembly 112 is located near the top of the material unloading frame 111, and includes a supporting driving member 1121 and a supporting plate 1122 that is transmission-connected to the supporting driving member 1121. The supporting plate 1122 is suitable for horizontally extending into the material unloading frame 111 under the drive of the supporting driving member 1121 to support the material trays 200 transported by the first transport mechanism 120. Preferably, there are two supporting assemblies 112 , which are disposed on both sides of the unloading frame 111 in the first horizontal direction. The supporting driving member 1121 is specifically a linear cylinder arranged along the first horizontal direction. The two supporting assemblies 112 are suitable for cooperating with the supporting material tray 200 .

[0080] The first receiving assembly 113 includes a first receiving module 1131 and a first receiving frame 1132 which is transmission-connected to the first receiving module 1131. The first receiving module 1131 is a linear module arranged in the vertical direction, and is located on one side of the blanking frame 111 in the second horizontal direction. The first receiving frame 1132 is accommodated in the blanking frame 111, and is suitable for being lifted and lowered in the vertical direction under the drive of the first receiving module 1131. The supporting assembly 112 and the first receiving assembly 113 are suitable for cooperating with each other to transfer the material tray 200 on the support plate 1122 to the blanking frame 111.

[0081] During operation, the supporting component 112 first moves into the material unloading frame 111 to be in the supporting position, and then the first conveying mechanism 120 conveys the material tray 200 to the supporting component 112, and then the first conveying mechanism 120 can continue to move to the first loading mechanism 130 to stack the empty material tray 200 after labeling on the material tray 200 at the material unloading frame 111. During this process, the first material receiving component 113 can move upward to support the material tray 200, and then the supporting component 112 can move out of the material unloading frame 111, so that the material tray 200 moves downward into the material unloading frame 111 driven by the first material receiving component 113.

[0082] Furthermore, the unloading mechanism 110 includes a first drawer assembly 114 received between the unloading frame 111 and the machine 300. The machine 300 has an entry and exit side. The unloading frame 111 is suitable for being pushed into or pulled away from the machine 300 from the entry and exit side under the action of the first drawer assembly 114. When the unloading frame 111 is pushed into the machine 300, it is suitable for cooperating with the first transport mechanism 120 to perform the material receiving operation. When the unloading frame 111 is pulled away from the machine 300, it is convenient for the operator to unload the material tray 200 in the unloading frame 111.

[0083] Preferably, the supporting assembly 112 and the first receiving assembly 113 are both arranged on the machine 300, so as to avoid the supporting assembly 112 and the first receiving assembly 113 moving synchronously with the blanking frame 111 when the blanking frame 111 is pushed or pulled, so as to facilitate the pushing and pulling operation of the blanking frame 111. Preferably, a first support member 1112 is fixed to the bottom of the blanking frame 111, and the first support member 1112 is a block structure. The first receiving frame 1132 is suitable for being lowered below the first support member 1112, so that the material tray 200 is supported by the first support member 1112. When the blanking frame 111 is pulled away from the machine 300, the blanking frame 111 can always effectively support the material tray 200. The first drawer assembly 114 is specifically a guide rail structure, which is arranged along the second horizontal direction, and the access side is located on one side of the machine 300 in the second horizontal direction. The first receiving module 1131 is arranged away from the access side to avoid hindering the pushing and pulling of the blanking frame 111. There are two first support members 1112, which are arranged opposite to each other along the first horizontal direction, and a hollow area is formed between the two first support members 1112 to avoid the first receiving frame 1132. The operator can apply a push-pull force to the side of the lower material frame 111 away from the first receiving module 1131, so that the lower material frame 111 slides relative to the machine 300 to a preset position along the second horizontal direction.

[0084] Further, refer to Figure 1 and Figure 3 As shown, the first feeding mechanism 130 includes a feeding frame 131 and a second material receiving assembly 132.

The labeling mechanism 140 includes a label printer 141 and a labeling assembly 142, and the labeling assembly 142 is received between the label printer 141 and the first feeding mechanism 130 to transfer and attach the label at the label printer 141 to the material tray 200 in the feeding position.

[0085] Specifically, the label printer 141 is arranged adjacent to the first feeding mechanism 130. The labeling assembly 142 includes a labeling module 1421 and a labeling head 1422 that is drivingly connected to the labeling module 1421. The labeling head 1422 is a vacuum adsorption structure and is adapted to move along the first horizontal direction under the drive of the labeling module 1421 to directly above the discharging position of the label printer 141 or directly above the feeding position of the first feeding mechanism 130, and move up and down along the vertical direction under the drive of the labeling module 1421, so that the labeling head 1422 adsorbs the label at the label printer 141 or attaches the label to the tray 200.

[0086] Preferably, a second support member 1311 for supporting the tray 200 is provided at the bottom of the feeding frame 131. The second receiving rack 1322 is adapted to descend below the second support member 1311 to support the tray 200 on the second support member 1311.

The clamping assembly 122 includes a clamping driving member 1221 and two clamping members 1222 drivingly connected to the clamping driving member 1221. The clamping driving member 1221 is a clamping cylinder. The two clamping members 1222 are arranged oppositely and are adapted to move towards each other under the drive of the clamping driving member 1221 to clamp the tray 200, or move away from each other to release the tray 200. Preferably, an embedding structure is provided on the opposite surface of each of the two clamping members 1222. The side of the tray 200 is adapted to be embedded in the embedding structure. The embedding structure includes two oppositely arranged convex portions 1223, and an embedding groove 1224 is formed between the two convex portions 1223.

The carrier 433 is suitable for moving to the bottom of the second loading mechanism 410 under the drive of the first circulation module 431, and extending into the second loading mechanism 410 under the drive of the first lifting module 432 to receive the material tray 200.

[0090] The positioning table 420 and the second loading mechanism 410 are arranged side by side along the second horizontal direction. The positioning table 420 includes a bracket 421, a fixed positioning block 422, a movable positioning block 423, and a positioning driving member 424. The brackets 421 are oppositely arranged on both sides of the first transfer mechanism 430 along the first horizontal direction. A bearing plate 4211 is provided at the top of each of the two brackets 421. The two bearing plates 4211 are adapted to cooperate to support the tray 200. An avoidance space for the lifting of the carrier 433 is formed between the two bearing plates 4211. Both the fixed positioning block 422 and the movable positioning block 423 are L-shaped blocks. There are three fixed positioning blocks 422. Two of the fixed positioning blocks 422 are arranged on both sides of one bearing plate 4211 in the second horizontal direction, and the other fixed positioning block 422 and the movable positioning block 423 are arranged on both sides of the other bearing plate 4211 in the second horizontal direction. The positioning driving member 424 is installed on the bracket 421 and is in transmission connection with the movable positioning block 423. The positioning driving member 424 is a linear cylinder, and its telescopic direction is parallel to the diagonal of the tray 200. The movable positioning block 423 and several fixed positioning blocks 422 respectively correspond to the four corners of the tray 200. After the tray 200 is placed on the bearing plate 4211, the movable positioning block 423 is adapted to approach the tray 200 under the drive of the positioning driving member 424, thereby realizing the precise positioning of the tray 200 in the horizontal direction.

[0091] The process of the positioning table 420 receiving materials is as follows: When the first transfer mechanism 430 receives the tray 200 at the second loading mechanism 410, the carrier 433 moves upward under the drive of the first lifting module 432 so that the tray 200 is located above the bearing plate 4211. Then the carrier 433 moves between the two brackets 421 under the drive of the first transfer module 431. The carrier 433 moves downward under the drive of the first lifting module 432 to place the tray 200 on the bearing plate 4211. Then, the precise positioning of the tray 200 in the horizontal direction is realized through the mutual cooperation of the movable positioning block 423 and the fixed positioning block 422.

[0092] Further, referring to Figure 6 、 Figure 8 and Figure 9As shown, a plurality of tray arranging mechanisms 440 are arranged side by side along the first horizontal direction, and the positioning table 420 is arranged side by side on one side of the tray arranging mechanism 440 on the side. The second transfer mechanism 450 is located on one side of the tray arranging mechanism 440 in the second horizontal direction, and includes a second transfer module 451, a second lifting module 452 and a suction cup assembly 453. Both the second transfer module 451 and the second lifting module 452 are linear modules. The second transfer module 451 is arranged along the first horizontal direction, the second lifting module 452 is drivingly connected to the second transfer module 451 and is arranged along the vertical direction. The suction cup assembly 453 is located above the positioning table 420 and / or the tray arranging mechanism 440 and is drivingly connected to the second lifting module 452. The suction cup assembly 453 can be driven by the second transfer module 451 to move directly above the positioning table 420 or the tray arranging mechanism 440, and pick and place the tray 200 in cooperation with the second lifting module 452.

[0093] In this embodiment, the number of the first tray arranging mechanism 440a, the second tray arranging mechanism 440b and the third tray arranging mechanism 440c is two. The tray arranging mechanism 440 includes a tray arranging frame 441, an upper fixture assembly 442, a lower fixture assembly 443 and a tray arranging module 444. The tray arranging frame 441 extends along the second horizontal direction. The upper fixture assembly 442 and the lower fixture assembly 443 are both slidably arranged on the tray arranging frame 441 along the second horizontal direction. The upper fixture assembly 442 and the lower fixture assembly 443 are arranged staggeredly to avoid mutual limitation during the sliding process. Both the upper fixture assembly 442 and the lower fixture assembly 443 are used to carry the tray 200, and the upper fixture assembly 442 and the lower fixture assembly 443 are platforms provided with positioning structures. The tray arranging module 444 is drivingly connected to the upper fixture assembly 442 and the lower fixture assembly 443 respectively. The tray arranging module 444 is specifically a belt drive module, which is adapted to drive the upper fixture assembly 442 and the lower fixture assembly 443 to move towards or away from each other along the second horizontal direction, so that one of the upper fixture assembly 442 and the lower fixture assembly 443 is in the first position for picking and placing the tray 200, and the other is in the second position for placing the product.

[0094] The fixture assembly in the first position is arranged side by side with the positioning table 420 and is adjacent to the first handling mechanism 120. The second transfer mechanism 450 can place the empty tray 200 on the fixture assembly in the first position; the fixture assembly in the second position is close to the blanking station for the products flowing out after detection. When the detected products flow to the blanking station, the second handling mechanism 460 can transport the corresponding category of products into the tray 200 in the second position. Until the tray 200 is full, the tray arranging module 444 drives it back to the first position.

[0095] Refer to Figure 1As shown, the second handling mechanism 460 includes a second manipulator 461 and a nozzle assembly 462 connected to the output end of the second manipulator 461. The nozzle assemblies 462 are preferably multiple and arranged side by side, and each nozzle assembly 462 can be independently lifted and lowered, thereby effectively improving the picking and placing efficiency of products. The first handling mechanism 120 is adapted to transport the pallet 200 full of products from the first position and stack it at the storage position 510. Preferably, a cross-movement module 123 is provided between the first handling mechanism 120 and the machine table 300. The cross-movement module 123 is a linear module arranged along the second horizontal direction, and the cross-movement module 123 is adapted to drive the first handling mechanism 120 to move along the second horizontal direction to increase its handling range and ensure reliable handling of the pallet 200 at the first position, the storage rack 500, and the labeling device 100.

[0096] The working process of the labeling device 1000 of the present invention is as follows: The second feeding mechanism 410, the positioning table 420, and the first transfer mechanism 430 cooperate with each other to load the empty pallet 200 onto the positioning table 420. The second transfer mechanism 450 loads the pallet 200 on the positioning table 420 to the first position of the palletizing mechanism 440, and repeats the above actions until each palletizing mechanism 440 completes the loading; when the palletizing mechanism 440 receives the empty pallet 200, the palletizing mechanism 440 moves the pallet 200 from the first position to the second position, and the second handling mechanism 460 transports the detected products to the pallet 200 at the second position. During this process, the second transfer mechanism 450 can continue to load the empty pallet 200 onto another fixture assembly at the first position; when the pallet 200 at the second position is full, the palletizing mechanism 440 drives it back to the first position, and the first handling mechanism 120 can transfer the pallet 200 full of products to the corresponding storage position 510 one by one. When the storage position 510 stacks a preset number of pallets 200, the first handling mechanism 120 transfers the stack of pallets 200 to the corresponding unloading mechanism 110, and then stacks the empty pallet 200 after labeling on top of the stack of pallets 200 to achieve marking and partitioning of the stack of pallets 200, and repeats the above actions until the unloading mechanism 110 is full; when the unloading mechanism 110 is full, the operator can pull out the full unloading mechanism 110 from the machine table 300 for unloading operations, and then push it back into the machine table 300 to continue receiving pallets 200.

[0097] Further, referring to Figure 10As shown, the present invention also provides an appearance inspection system, including a feeding device 2000, a detection device 3000 and the aforementioned labeling device 1000, wherein the detection device 3000 is used to inspect the appearance of a product, and has a feeding station and a unloading station, the feeding device 2000 is suitable for feeding the product to be inspected to the feeding station, the detection device 3000 is suitable for flowing the inspected product to the unloading station, and the labeling device 1000 is suitable for receiving the inspected product. The feeding device 2000 is a conventional structure, and the present invention will not be repeated here.

[0098] Further, refer to Figures 11 to 14 As shown, the detection equipment 3000 includes: at least one first transfer device 600, which is arranged side by side along the first horizontal direction, the first transfer device 600 includes a first flipping mechanism 610 and a first transfer module 620 transmission-connected to the first flipping mechanism 610, the first flipping mechanism 610 includes a first carrier 611 for accommodating products, and a plurality of first carriers 611 are arranged side by side along the second horizontal direction; a detection device 800, including first detection cameras 810 corresponding one-to-one to the first transfer device 600, and the plurality of first carriers 611 on the first flipping mechanism 610 are suitable for sequentially flowing through the corresponding first detection cameras 810 along the second horizontal direction under the drive of the first transfer module 620.

[0099] Further, when the product is placed on the first carrier 611, the back of the product faces away from the first carrier 611. However, in the present embodiment, the detection system needs to detect the front, back and sides of the product. Preferably, the appearance detection system also includes a second transfer device 700, and there are multiple second transfer devices 700, which are arranged side by side along the first horizontal direction, and the first transfer device 600 and the second transfer device 700 correspond one to one. The second transfer device 700 includes a second flipping mechanism 710 and a second transfer module 720 connected to the second flipping mechanism 710 in a transmission manner. The second flipping mechanism 710 includes a second carrier 711 for accommodating the product. There are multiple second carriers 711 arranged side by side along the second horizontal direction. When the product is placed on the second carrier 711, the front of the product faces away from the second carrier 711. The inspection device 800 includes second inspection cameras 820 corresponding to the second transfer device 700 one by one. The plurality of second carriers 711 on the second flip mechanism 710 are suitable for sequentially passing through the corresponding second inspection cameras 820 along the second horizontal direction under the drive of the second transfer module 720 .

[0100] The first flipping mechanism 610 is adapted to move to the loading station or the docking station driven by the first transfer module 620, and the second flipping mechanism 710 is adapted to move to the docking station or the unloading station driven by the second transfer module 720. When the first flipping mechanism 610 and the second flipping mechanism 710 are both at the docking station, the first flipping mechanism 610 and the second flipping mechanism 710 are adapted to be docked with each other to transfer the product on the first carrier 611 to the second carrier 711. During operation, the loading device 2000 is adapted to load the product onto the first carrier 611 at the loading station. The first transfer module 620 drives the first flipping mechanism 610 to move from the loading station to the docking station, and the first carrier 611 sequentially passes under the corresponding first inspection camera 810 to realize the appearance inspection of the reverse side and part of the side of the product. The second transfer module 720 is adapted to drive the second flipping mechanism 710 to move to the docking station to receive the inspected product, and then the second transfer module 720 is adapted to drive the second flipping mechanism 710 to move from the docking station to the unloading station, and the second carrier 711 sequentially passes under the corresponding second inspection camera 820 to realize the appearance inspection of the front side and another part of the side of the product.

[0101] In this embodiment, the number of the first transfer devices 600 and the second transfer devices 700 is four groups each. The first transfer devices 600 and the second transfer devices 700 are located below the first inspection camera 810 and / or the second inspection camera 820. The first carrier 611 is adapted to sequentially pass directly below the corresponding first inspection camera 810 driven by the first transfer module 620, so that the first inspection camera 810 can take pictures of the product on the first carrier 611. The second carrier 711 is adapted to sequentially pass directly below the corresponding second inspection camera 820 driven by the second transfer module 720, so that the second inspection camera 820 can take pictures of the product on the second carrier 711. When the first flipping mechanism 610 and the second flipping mechanism 710 are at the docking station, the first flipping mechanism 610 and the second flipping mechanism 710 are arranged side by side in the first horizontal direction to ensure that the first flipping mechanism 610 and the second flipping mechanism 710 can be successfully docked.

[0102] Both the first transfer module 620 and the second transfer module 720 are conventional linear modules, which will not be elaborated in this invention. The first flipping mechanism 610 includes a bottom plate 612, a translation assembly 613, a first flipping seat 614, and a rotation assembly 615. The bottom plate 612 is fixed to the driving end of the first transfer module 620. The translation assembly 613 is disposed on the bottom plate 612 and is adapted to move along the first horizontal direction. The first flipping seat 614 is disposed on the translation assembly 613 and can rotate about an axis parallel to the second horizontal direction. The translation assembly 613 is adapted to drive the first flipping seat 614 to move synchronously along the first horizontal direction. The rotation assembly 615 is disposed on the first flipping seat 614 and is adapted to rotate about an axis perpendicular to the second horizontal direction. There are multiple rotation assemblies 615, and the first carriers 611 are respectively disposed on different rotation assemblies 615.

[0103] By adopting the above structure, the first carrier 611 is adapted to arrange the reverse side of the product facing up under the adjustment of the first flipping seat 614 to ensure that the first detection camera 810 can reliably obtain the reverse image of the product. And the first flipping seat 614 is adapted to drive the first carrier 611 to rotate about an axis parallel to the second horizontal direction, and cooperate with the rotation assembly 615 to drive the first carrier 611 to rotate about an axis perpendicular to the second horizontal direction, so that the first detection camera 810 can reliably obtain the side image of the product.

[0104] The structure of the second flipping mechanism 710 is the same as that of the first flipping mechanism 610, which will not be elaborated in this invention. When both the first flipping mechanism 610 and the second flipping mechanism 710 are in the docking station, the first flipping seat 614 of the first flipping mechanism 610 and the first flipping seat 614 of the second flipping mechanism 710 can flip towards each other, so that the first bearing surface 6111 of the first carrier 611 and the second bearing surface (not shown in the figure) of the second carrier 711 are in a docking state of relative arrangement. The first bearing surface 6111 and the second bearing surface are perpendicular to the first horizontal direction. Then, the translation assembly 613 can drive the first flipping seats 614 of the first flipping mechanism 610 and the second flipping mechanism 710 to approach each other, so that the product on the first carrier 611 is transferred to the second carrier 711.

[0105] Further, the first carrier 611 is an adsorption type carrier. Adsorption holes are formed on the first bearing surface 6111 of the first carrier 611, so that the front surface of the product can be reliably adsorbed on the first bearing surface 6111. A first fixed positioning structure 616 is arranged on the first bearing surface 6111. The first fixed positioning structure 616 is adapted to position the product in the direction perpendicular to the axis of the rotating assembly 615. In this embodiment, the product has a square-shaped structure. The first fixed positioning structure 616 is a positioning block whose outer contour is adapted to the inner edge of the product. After the product is placed on the first bearing surface 6111, the positioning block is embedded in the inner edge of the product to achieve the positioning of the product. The structure of the second carrier 711 is similar to that of the first carrier 611. It is also an adsorption type carrier. A second fixed positioning structure (not shown in the figure) for positioning the product is arranged on the second carrier 711, which will not be elaborated in this invention.

[0106] In the present invention, by arranging the first fixed positioning structure 616 on the first carrier 611 and the second fixed positioning structure on the second carrier 711, the position accuracy of the products placed on the first carrier 611 and the second carrier 711 is high, ensuring that the adsorption holes thereon can effectively correspond to the products, improving the reliability of the products on the first carrier 611 and the second carrier 711. Moreover, by adopting the fixed positioning structure, the structures of the first carrier 611 and the second carrier 711 can be simpler and smaller, and the adjacent carriers can be more compact, enabling the detection areas of the first detection camera 810 and / or the second detection camera 820 to cover more carriers and improving the detection efficiency.

[0107] Since the feeding device 2000 usually uses a manipulator structure to feed the products onto the first carrier 611, when using a fixed positioning structure, the accuracy requirements for the manipulator are relatively high, which is not conducive to cost reduction, and the manipulator needs to finely adjust its position, resulting in very low efficiency. While using a movable positioning structure will lead to a complex structure and an increase in the volume of the positioning structure.

[0108] As a preferred embodiment, the detection system further includes a transfer device 900 arranged at the feeding station. Referring to Figure 11 、 Figure 12 and Figure 15 and Figure 16 as shown, there are multiple transfer devices 900, which are in one-to-one correspondence with the first transfer device 600. The transfer device 900 includes a third flipping mechanism 910. The third flipping mechanism 910 includes multiple third carriers 911 corresponding to the first carriers 611 one by one. The feeding device 2000 is adapted to carry the products to the third carriers 911. The first flipping mechanism 610 is adapted to move to the feeding station driven by the first transfer module 620 and dock with the third flipping mechanism 910, so that the products on the third carriers 911 are transferred to the first carriers 611.

[0109] Specifically, the transfer device 900 includes a connecting frame 920. The third flipping mechanism 910 includes a second flipping seat 912 disposed on the connecting frame 920. The second flipping seat 912 is rotatable about an axis parallel to the second horizontal direction. The third carrier 911 is disposed on the second flipping seat 912. The product is adapted to be placed on the third carrier 911 with its front face facing away from the third carrier 911. A third fixed positioning structure 913 is provided on the third carrier 911, and a movable positioning structure 914 is provided on the second flipping seat 912. The movable positioning structure 914 may specifically adopt a structure of a cylinder cooperating with a positioning block. The movable positioning structure 914 can approach the third fixed positioning structure 913 to cooperate with the third fixed positioning structure 913 to position the product. When the first flipping mechanism 610 is at the loading station, the third flipping mechanism 910 and the first flipping mechanism 610 are arranged side by side along the first horizontal direction to facilitate docking between the two.

[0110] With the above structure adopted in the present invention, the third carrier 911 positions the product by means of the cooperation between the movable positioning structure 914 and the third fixed positioning structure 913. When the loading device 2000 loads the product onto the third carrier 911, the requirement for the position accuracy of the product is relatively low, which facilitates the efficient loading of the loading device 2000. Moreover, after the product is placed on the third carrier 911, the movable positioning structure 914 can move closer to the third fixed positioning structure 913 to achieve precise positioning of the product.

[0111] 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 equally included in the patent protection scope of the present application.
