Detailed Implementation

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] It should be noted that the control system and control method mentioned in this application are easily implemented by those skilled in the art. The main description in this application focuses on the structure of the detection equipment, not the control method. The mention of the control system is merely for the convenience of explaining the working principle of the detection equipment. The control system includes, but is not limited to, a PLC control system. In the embodiments of this application, the first preset path W1, the second preset path W2, and the third preset path W3 are... Figure 2 The path shown.

[0054] like Figures 1-7 As shown in the illustration, this application provides a product testing device, including a frame. The frame is equipped with a feeding mechanism 1, a loading mechanism 2, a testing mechanism 3, a unloading mechanism 4, and a control system. The feeding mechanism 1, loading mechanism 2, testing mechanism 3, and unloading mechanism 4 are all electrically connected to the control system. The loading mechanism 2 is located between the feeding mechanism 1 and the testing mechanism 3, and the unloading mechanism 4 is located to one side of the testing mechanism 3. The feeding mechanism 1 has a feeding module and a loading station 10. The feeding module moves a tray loaded with products into the loading station 10 and moves an empty tray out of the loading station 10. The loading mechanism 2 includes a gripping component 21 and a barcode scanning component 22. The barcode scanning component 22 is located below the gripping component 21. The gripping component 21 grips the product and moves it along a first preset path W1 from the loading station 10. The product is moved to the scanning component 22 for scanning. After scanning, the product continues to move along the first preset path W1 and is transferred to the detection platform 31 of the detection mechanism 3. The detection mechanism 3 has a detection platform 31 and a detection component 32 for receiving products. The detection platform 31 and / or the detection component 32 move, such as the detection platform 31 moving on the second preset path W2 and the detection component 32 moving on the third preset path W3, so that the detection component 32 is close to the detection platform 31 to detect the product carried on the detection platform 31. The unloading mechanism 4 has a sorting component 41, an OK unloading station 50 and an NG unloading station 60. The sorting component 41 sorts the products on the detection platform 31 and puts them into the OK unloading station 50 and the NG unloading station 60 respectively for unloading.

[0055] The feeding module of the feeding mechanism 1 moves the pallet loaded with products into the loading station 10; the gripping component 21 transfers the product from the loading station 10 along the first preset path W1 to above the barcode scanning component 22, so that the barcode scanning component 22 can scan the product to determine the product parameters and send the product parameter information to the control system; then, the gripping component 21 transfers the product to the detection platform 31; the detection platform 31 moves on the second preset path W2 and / or the detection component 32 moves on the third preset path W3, that is, the detection platform 31 moves on the second preset path W2 or the detection component 32 moves on the third preset path W3, or the detection platform 31 and the detection component 32 move simultaneously, so that the detection component 32 moves closer to the detection platform 31, such as the detection component 32... Above the products carried on the inspection platform 31, the control system controls the inspection component 32 to perform corresponding inspections on the products based on the product parameters provided by the barcode scanning component 22, such as inspecting the product's step difference. After the inspection is completed, the control system controls the sorting component 41 of the unloading mechanism 4 to sort the products on the inspection platform 31 based on the inspection results of the inspection component 32, and place them into the OK unloading station 50 and NG unloading station 60 respectively for unloading. After the gripping component 21 has gripped all the products in the pallet at the loading station 10, the control system controls the feeding module to move the empty pallet out of the loading station 10 and place a new pallet loaded with products into the loading station 10 to continue the work of scanning, inspecting, sorting and unloading the products.

[0056] Therefore, the product testing equipment of this application automatically performs fully automated testing on the products, which can improve the testing efficiency and ensure the product's factory qualification rate.

[0057] like Figures 3-5As shown, the testing mechanism 3 includes at least two testing platforms 31, which are arranged along a first direction that can be parallel to a second preset path W2. Each testing platform 31 is provided with at least one testing station 20, and each testing station 20 has multiple product fitting positions for carrying products. Each testing platform 31 can move to change its position relative to the gripping component 21, the testing component 32, and the unloading mechanism 4, so as to switch different products to be tested under the testing component 32. Multiple products are loaded at one testing station 20 for one test, and the test is completed. Subsequently, based on the test results and under the control of the control system, the product is transferred to the corresponding OK unloading station 50 or NG unloading station 60. When a test station 20 carries a product under the test component 32, other test stations 20 can transfer the product to the unloading mechanism 4 for unloading. Other test stations 20 can move to the gripping component 21 to receive the scanned product delivered by the gripping component 21. Multiple test stations 20 work together to enable loading, scanning, testing and unloading to be performed simultaneously, thereby improving the efficiency of product testing.

[0058] The inspection mechanism 3 is also equipped with an OK transfer station 30 and an NG transfer station 40. The OK transfer station 30 and the NG transfer station 40 are arranged along the second preset path W2, i.e., the first direction, and are located between the inspection station 20 and the unloading mechanism 4. This arrangement can simplify the drive mechanism that drives the inspection station 20 to move, optimize the layout between the inspection station 20 and the OK transfer station 30 and the NG transfer station 40, shorten the travel of the inspection platform 31, and speed up the inspection and unloading of products.

[0059] The detection component 32 can move on the third preset path W3. The detection component 32 forms a detection area below the third preset path W3. Each detection platform 31 moves on the second preset path W2 to switch different detection stations 20 to enter the detection area. The detection component 32 moves on the third preset path W3, moving closer to or away from the detection platform 31. When the detection component 32 moves closer to the detection platform 31, it detects the product on the detection platform 31 so that the control system can determine whether the product is qualified. If it is qualified, it is an OK product; if it is unqualified, it is an NG product.

[0060] After all the products on an inspection platform 31 have been inspected, the inspection platform 31 can be moved out of the inspection area and close to the OK transfer station 30 and the NG transfer station 40, so that the next inspection platform 31 can be moved into the inspection area to inspect the products on it. The products on the inspection platform 31 will be sorted and unloaded by the unloading mechanism 4.

[0061] The sorting component 41 is used to sort the products on the inspection station 20 that have completed inspection and place them into the OK transfer station 30 and NG transfer station 40 respectively. After all the products on an inspection station 20 have been inspected, the control system controls the sorting component 41 to pick up the OK products and NG products on this inspection station 20 according to the inspection results and place them into the OK transfer station 30 and NG transfer station 40 respectively. After sorting is completed, the inspection platform 31 that has completed sorting moves to make room for other inspection stations 20 that have completed inspection, so that the sorting component 41 can continue to pick up products for sorting.

[0062] The unloading mechanism 4 also includes an unloading component 42, which is used to move products from the OK transfer station 30 to the OK unloading station 50 and to move products from the NG transfer station 40 to the NG unloading station 60, and then unload OK products and NG products respectively.

[0063] The testing platform 31 moves horizontally along the second preset path W2, and the testing component 32 moves vertically along the third preset path W3. The testing component 32 is always located above the testing platform 31. The testing platform 31 can carry the product and move it to the area below the testing component 32 for product testing.

[0064] The testing mechanism 3 also includes a testing support frame 33 and a first lifting module 34. The testing support frame 33 has multiple horizontally extending slides spaced apart. The testing platform 31 is slidably connected to the slides via a slide block. The testing platform 31 is driven to move along the slides, realizing movement on the second preset path W2, so as to enter the testing area or approach the OK transfer station 30 or the NG transfer station 40. The first lifting module 34 is located on one side of the testing platform 31 and is connected to the testing component 32. The testing component 32 is driven by the first lifting module 34 to rise and fall along the third preset path W3, so as to approach the product in the testing station 20 and test the product.

[0065] The detection platform 31 can be driven horizontally by a drive mechanism commonly used in the prior art.

[0066] The first lifting module 34 can be driven by common mechanisms such as cylinders, lead screw and nut mechanisms, linear motors, or gear and rack mechanisms. The configuration of the first lifting module 34 can refer to the configuration in the existing technology.

[0067] Optionally, the detection component 32 may be a 3D line scan camera. A 3D line scan camera is an industrial camera that reconstructs the three-dimensional shape of an object surface through laser triangulation. It can be used for the detection of various precision parts, such as detecting the step difference of a product.

[0068] Optionally, this application uses a 3D line scan transfer platform to move the product. The 3D line scan transfer platform includes the aforementioned detection support frame 33 and detection platform 31. The specific structure of the 3D line scan transfer platform is well known to those skilled in the art, and the technical details of the 3D line scan transfer platform will not be described in detail here.

[0069] The gripping component 21 moves along the first preset path W1, and the scanning component 22 is positioned below the first preset path W1. The gripping component 21 transfers multiple products from the loading station 10 to the top of the scanning component 22 for scanning at once. The scanning component 22 includes multiple barcode scanners 221, which can scan multiple products simultaneously. After scanning, the gripping component 21 transfers the products to the inspection platform 31. Furthermore, the multiple barcode scanners 221 are evenly spaced along the second preset path W2 on one side of the inspection platform 31. This arrangement optimizes the layout between the gripping component 21 and the inspection platform 31 and reduces the travel distance of the gripping component 21 along the first preset path W1.

[0070] Specifically, the gripping assembly 21 includes a gripping robot 211, an assembly bracket 212, and multiple gripping heads 213. The drive end of the gripping robot 211 is connected to the assembly bracket 212. The assembly bracket 212 has multiple assembly parts 212a. Each assembly part 212a is equipped with a product front and back recognition sensor, which is electrically connected to the control system. The gripping heads 213 are connected to the assembly parts 212a one by one. Each set of gripping heads 213 includes at least one adsorption component 213a. In any set of gripping heads 213, the adsorption component 213a is disposed on the assembly part 212a. The feeding mechanism 2 also includes a negative pressure assembly 23. The adsorption component 213a is connected to the inside of the assembly part 212a, the inside of the assembly bracket 212, and the negative pressure assembly 23. The negative pressure assembly 23 forms a negative pressure at the opening at the end of the adsorption component 213a.

[0071] Under the control of the control system, the gripping robot 211 drives the gripping head 213 to move to the loading station 10, so that the gripping head 213 can adsorb the product. In order to pick up the product more stably and reliably for transfer, multiple adsorption components 213a can be set up. Multiple adsorption components 213a in each gripping head 213 simultaneously pick up one product, which can pick up the product more stably for transfer. The product is transferred to the barcode scanner 221 for scanning. After scanning, the product is transferred to the detection platform 31.

[0072] When the gripping robot 211 drives the gripping head 213 to the loading station 10, the product front and back recognition sensor identifies the front and back of the product by the notch on the product or the difference in height between the front and back of the product and the sensor after the product is placed, and sends the result to the control system. The control system controls the negative pressure component 23 accordingly to determine whether a negative pressure is formed at the end opening of the adsorption component 213a of the corresponding gripping head 213. If the product needs to be transferred, a negative pressure will be formed at the end opening of the adsorption component 213a of the corresponding gripping head 213. If the product does not need to be transferred, a negative pressure will not be formed at the end opening of the adsorption component 213a of the corresponding gripping head 213, so that the product remains in the loading station 10 and is transferred and unloaded by the feeding mechanism 1 along with the tray.

[0073] In each set of gripping heads 213, each adsorption component 213a is positioned relative to the assembly part 212a. When there are multiple adsorption components 213a, the shape formed by the adsorption components 213a surrounding the assembly part 212a can be changed by adjusting the position of the adsorption components 213a relative to the assembly part 212a to adapt to products of different sizes. Each set of gripping heads 213 steadily picks up the product and transfers it under the drive of the gripping robot arm 211.

[0074] Optionally, an adjustment bracket 212b is provided on each assembly part 212a of the assembly bracket 212. One adjustment bracket 212b corresponds to one gripping head 213. Each adjustment bracket 212b is provided with multiple adjustment holes 212c. The adjustment holes 212c can be oblong holes. The number of adjustment holes 212c is equal to or greater than the number of adsorption components 213a. One adsorption component 213a is locked inside the adjustment hole 212c by two adjustment nuts 212d. Specifically, the two nuts are threaded to the outside of the adsorption component 213a, and the two nuts abut against the vertical adjustment hole 212c. On opposite sides, these two nuts can be manually adjusted to adjust the position of the adsorption component 213a relative to the adjustment hole 212c in the vertical and horizontal directions. Thus, in a gripping head 213, adjusting the position of at least one adsorption component 213a relative to other adsorption components 213a can change the shape formed by these adsorption components 213a to adapt to products of different sizes. According to the size of the product, the position of the adsorption component 213a is adjusted to adjust the position of the force point of the product when adsorbing it, so as to firmly adsorb the product and transfer it in conjunction with the gripping robot 211.

[0075] As a preferred embodiment, the adsorption component 213a includes a suction nozzle with a negative pressure connection hole. The negative pressure connection hole can be connected to the negative pressure assembly 23 via an air tube through the assembly part 212a and the assembly bracket 212. Alternatively, the suction nozzle can be directly connected to the negative pressure assembly 23. The negative pressure assembly 23 can be a structure commonly used in the prior art. The negative pressure assembly 23 includes a vacuum pump and a number of negative pressure tubes corresponding to the gripping head 213. That is, one negative pressure tube corresponds to and is connected to all adsorption components 213a of a gripping head 213. The vacuum pump can draw suction to form a negative pressure at the end opening of the adsorption component 213a.

[0076] In addition, a buffer 213b, such as a spring or other elastic element, is provided at the end of the adsorption component 213a. When adsorbing the product, the end of the adsorption component 213a can form a flexible contact with the product, reducing the impact on the product.

[0077] As a preferred method, the gripping robot 211 can be a four-axis robot, a six-axis robot, etc.

[0078] As a preferred method, the sorting component 41 uses a spider robot.

[0079] like Figure 3 and Figures 6-10 As shown, the feeding mechanism 4 also includes a transfer component 43 and a load-bearing component 44.

[0080] The transfer assembly 43 has a transfer support frame 431, which has an OK unloading station 50 and an NG unloading station 60. The transfer assembly 43 drives and controls the unloading assembly 42 to move between the inspection platform 31 and the transfer support frame 431. When the unloading assembly 42 moves close to the inspection platform 31, it moves the product at the OK transfer station 30 into the OK unloading station 50 on the transfer support frame 431 and moves the product at the NG transfer station 40 into the NG transfer station 40 on the transfer support frame 431. OK products are placed on empty pallets at the OK unloading station 50 by the unloading assembly 42, and NG products are placed on empty pallets at the NG unloading station by the unloading assembly 42. The carrying assembly 44 is located below the transfer support frame 431. The carrying assembly 44 receives the pallets transferred from the transfer assembly 43 and stacks them together for unloading.

[0081] The transfer assembly 43 also includes two sets of transfer support drive components mounted on the transfer support frame 431. These transfer support drive components can be cylinders, and the drive ends of both sets of transfer support drive components are correspondingly connected to transfer support plates 433, meaning there are two sets of transfer support plates 433. Transfer drive components 432 are mounted on the transfer support frame 431, and their drive ends are connected to the unloading assembly 42. The transfer drive components 432 drive the unloading assembly 42 to move between the detection platform 31 and the transfer support frame 431. One set of transfer support plates 432... A transfer support plate 433 surrounds the outer periphery of the OK unloading station 50, and the transfer support plate 433 moves away from and towards the OK unloading station 50 under the drive of the transfer support drive member to release or contact the side of the pallet so that the pallet falls onto the lower support component 44; another set of transfer support plates 433 surrounds the outer periphery of the NG unloading station 60, and the transfer support plate 433 moves away from and towards the NG unloading station 60 under the drive of the transfer support drive member to release or contact the side of the pallet so that the pallet falls onto the lower support component 44.

[0082] Optionally, the transfer drive component 432 includes a transfer drive motor 432a, a transfer drive shaft 432b, a drive wheel 432c, a driven wheel 432d, and a synchronous belt 432e; the transfer support frame 431 is provided with two parallel slide rails, and the OK unloading station 50 and the NG unloading station 60 are located between these two slide rails; the transfer drive motor 432a is mounted on the transfer support frame 431, and the power end of the transfer drive motor 432a is connected to the transfer drive shaft 432b via a coupling; the drive wheel 432c and the driven wheel 432d are both movably mounted on the slide rails. The transfer drive shaft 432b and the drive wheel 432c are connected by a transmission, and the synchronous belt 432e is wrapped around the outer circumference of both the drive wheel 432c and the driven wheel 432d. The unloading assembly 42 is slidably connected to two slide rails, and the unloading assembly 42 is connected to the synchronous belt 432e. The transfer drive motor 432a can drive the transfer drive shaft 432b to rotate, thereby driving the drive wheel 432c, the driven wheel 432d, and the synchronous belt 432e to rotate, thus driving the unloading assembly 42 to slide along the slide rails, so that the unloading assembly 42 moves back and forth between the detection platform 31 and the transfer support frame 431.

[0083] The transfer drive unit 432 also includes a tension wheel 432f, which is mounted on the slide rail and can be adjusted relative to the slide rail, such as vertically. The tension wheel 432f adjusts the tension of the timing belt 432e so that the timing belt 432e is taut and can smoothly drive the unloading assembly 42 to slide.

[0084] In a preferred embodiment, both ends of the transfer drive shaft 432b are provided with drive wheels 432c, which are respectively mounted on two slide rails. Driven wheels 432d and tension wheels 432f are also provided on the two slide rails. Two synchronous belts 432e are respectively wrapped around the outer periphery of the corresponding drive wheel 432c, tension wheel 432f, and driven wheel 432d, and both synchronous belts 432e are connected to the unloading assembly 42. The transfer drive motor 432a drives the two synchronous belts 432e to slide the unloading assembly 42 relatively smoothly, so that the unloading assembly 42 steadily moves the product on the inspection platform 31 into the OK unloading station 50 or NG unloading station 60 of the transfer support frame 431.

[0085] In other preferred embodiments, the transfer drive 432 can be a lead screw and nut mechanism, a gear and rack mechanism, a linear motor, or a cylinder to drive the unloading assembly 42 to move; the arrangement of the lead screw and nut mechanism, gear and rack mechanism, linear motor, and cylinder can refer to the common methods in the prior art, and will not be described in detail here.

[0086] The unloading assembly 42 includes an unloading slide rail 421, an unloading drive component 422, and an unloading gripping module 423.

[0087] The direction of movement of the unloading component 42 is perpendicular to the second preset path W2 of the detection platform 31. The extension direction of the unloading slide rail 421 is parallel to the second preset path W2, and the unloading slide rail 421 is mounted on the transfer support frame 431. The unloading slide rail 421 can be connected to the synchronous belt 432e in the above embodiment, or it can be connected to the drive end of a screw and nut mechanism, a gear and rack mechanism, a linear motor, or a cylinder. The main body of the unloading drive component 422 is mounted on the unloading slide rail 421, and the unloading gripper... Module 423 is movably connected to the unloading slide rail 421. The drive end of the unloading drive component 422 is connected to the unloading gripping module 423. The unloading drive component 422 drives the unloading gripping module 423 to move along the unloading slide rail 421 to approach the OK transfer station 30 or the NG transfer station 40, so that the unloading gripping module 423 will move the product from the OK transfer station 30 into the tray of the OK unloading station 50, or move the product from the NG transfer station 40 into the tray of the NG unloading station 60.

[0088] Alternatively, the feeding drive 422 may use an existing known drive structure, such as a motor, the technical details of which will not be disclosed here.

[0089] Optionally, the unloading gripping module 423 can be driven by a linear drive device such as a cylinder, linear motor, lead screw and nut mechanism or gear and rack mechanism to move its vacuum suction cup, so as to pick up the products in the OK transfer station 30 or NG transfer station 40, and place the products in the OK unloading station 50 and NG unloading station 60 respectively.

[0090] The feeding mechanism 4 also includes two sets of first dismantling components 45 and dismantling support frame 46.

[0091] The tray removal support frame 46 is positioned above the transfer support frame 431. The tray removal support frame 46 has two tray removal holes 461. Two sets of first tray removal components 45 are both positioned on the tray removal support frame 46 and correspond to the tray removal holes 461 respectively. One set of first tray removal components 45 separates the stacked trays and allows the trays to fall onto the supporting component 44 below. The other set of first tray removal components 45 also separates the stacked trays and allows the trays to fall onto the supporting component below.

[0092] Each set of first dismantling components 45 includes multiple first guide posts 451 and multiple first side push drive members 452. The multiple first guide posts 451 are arranged on the dismantling support frame 46 around their corresponding dismantling holes 461, and are used to guide and limit the pallet at the dismantling holes 461 to prevent the pallet from tilting. The main body of the multiple first side push drive members 452 is arranged on the dismantling support frame 46 around the dismantling holes 461. The drive end of the first side push drive member 452 is connected to a first dismantling receiving plate 453. The first side push drive member 452 drives and controls the first dismantling receiving plate 453 to move away from and towards the dismantling holes 461, so as to release or contact the side of the pallet so that the pallet can fall onto the transfer component 43 below.

[0093] Each disassembly hole 461 corresponds to at least two first side-push drive members 452. The first side-push drive members 452 drive the first disassembly receiving plate 453 to move away from the disassembly hole 461, thereby loosening the side of the pallet and separating the first disassembly receiving plate 453 from the side of the pallet. This allows the bottommost pallet located at the disassembly hole 461 to descend onto the transfer assembly 43 below. After the bottommost pallet descends onto the transfer assembly 43, the first side-push drive members 452 drive the first disassembly receiving plate 453 towards the disassembly hole 461, thereby allowing the first disassembly receiving plate 453 to move towards the disassembly hole 461. A dismantling receiving plate 453 catches the side of the second-to-last pallet, providing positioning support for the side of the second-to-last pallet, thereby securing all the remaining pallets at the dismantling hole 461. Subsequently, the transfer drive 432 drives the unloading assembly 42 to move between the OK transfer station 30 or NG transfer station 40 and the transfer support frame 431, so that the unloading assembly 42 moves the products in the OK transfer station 30 or NG transfer station 40 into the OK unloading station 50 and NG unloading station 60 on the transfer support frame 431, respectively.

[0094] Optionally, the first side-push drive component 452 is preferably a cylinder, a hydraulic cylinder, or a motor, and the motor can be a linear drive structure such as a linear motor.

[0095] Two load-bearing components 44 are set below the transfer support frame 431. One load-bearing component 44 corresponds to the OK unloading station 50, and the other load-bearing component 44 corresponds to the NG unloading station 60.

[0096] Each load-bearing component 44 includes a load-bearing slide rail 441, a load-bearing drive (not shown in the attached drawings), and a load-bearing seat 442. The load-bearing slide rail 441 extends vertically. The main body of the load-bearing drive is connected to the load-bearing slide rail 441. The load-bearing seat 442 is slidably connected to the load-bearing slide rail 441. The drive end of the load-bearing drive is connected to the load-bearing seat 442. The load-bearing drive drives the load-bearing seat 442 to move upward to near the OK unloading station 50 / NG unloading station 60. When the transfer support plate 433 is driven away from the OK unloading station 50 or NG unloading station 60 to loosen the side of the pallet, the load-bearing seat 442 receives the pallet and stacks it. After a certain number of pallets are received on the load-bearing seat 442, the load-bearing seat 442 is driven downward by the load-bearing drive to pull out all the pallets. Optionally, the load-bearing drive can be an existing known drive structure such as a motor with a synchronous belt. Its technical details are not disclosed here.

The second tray removal component 12 is located at the loading station 10 and is used to stack trays filled with products and send the trays one by one to the loading station 10; the feeding component 11 is located at the loading station 10 and is used to receive individual trays and move them to the recycling station 70 so that the recycling component 13 can recycle the trays.

[0098] The second dismantling assembly 12 includes multiple second side-push drive components 121 and a dismantling slide 122. The main bodies of the multiple second side-push drive components 121 are arranged around the loading station 10. The drive end of the second side-push drive component 121 is connected to the second dismantling receiving plate 123. The dismantling slide 122 is vertically slidably arranged below the loading station 10. The dismantling slide 122 slides upward to deliver the tray full of products it carries to the loading station 10. After the gripping component 21 removes the products one by one from the top tray on the dismantling slide 122, the second side-push... The drive unit 121 drives the second dismantling receiving plate 123 to move towards the loading station 10 to contact the side of the topmost pallet and receive the topmost pallet, thus separating the topmost pallet from the remaining pallets on the dismantling slide 122. Then, the feeding component 11 transfers this pallet to the recycling station 70, so that the recycling component 13 can recycle the pallet. Whenever the gripping component 21 removes the product from the pallet at the loading station 10, the pallet will be separated by the second dismantling component 12, and the feeding component 11 will transfer it to the recycling station 70.

[0099] The feeding assembly 11 includes a feeding slide rail 111, a feeding drive component 112, and a feeding gripping module 113.

[0100] The extension direction of the feeding slide rail 111 is parallel to the second preset path W2. The main body of the feeding drive 112 is connected to the feeding slide rail 111. The feeding gripping module 113 is movably connected to the feeding slide rail 111. The drive end of the feeding drive 112 is connected to the feeding gripping module 113. The feeding drive 112 drives the feeding gripping module 113 to move along the feeding slide rail 111 to approach the loading station 10 or the recycling station 70, so that the feeding gripping module 113 will transfer the empty pallet at the loading station 10 to the recycling station 70.

[0101] Alternatively, the feeding drive 112 can be a known existing drive structure, the technical details of which will not be disclosed here.

[0102] The feeding gripping module 113 can use a vacuum suction cup or a pneumatic gripper to pick up the tray, so as to transfer the tray at the loading station 10 to the recycling station 70 under the drive of the feeding drive unit 112. The detailed structure of the feeding gripping module 113 can refer to the common structures in the prior art, and its technical details will not be disclosed here.

[0103] The recycling assembly 13 includes a recycling slide rail 131, a recycling drive (not shown in the attached drawings), and a recycling slide block 132. The recycling slide rail 131 extends vertically. The main body of the recycling drive is connected to the recycling slide rail 131. The recycling slide block 132 is slidably connected to the recycling slide rail 131. The drive end of the recycling drive is drively connected to the recycling slide block 132. The recycling drive drives the recycling slide block 132 to move upward to near the recycling station 70, so that the recycling slide block 132 receives and stacks the pallets conveyed from the feeding assembly 11. After a certain number of pallets are held on the recycling slide block 132, the recycling slide block 132 is driven downward by the recycling drive to pull out all the pallets. Optionally, the recycling drive can use an existing known drive structure, the technical details of which are not disclosed here.
