[0002] The negative electrode current collector of a large cylindrical battery is one of the key components inside the battery. Its main function is to collect electrons generated by the negative electrode active material and conduct them to the external circuit. At the same time, it supports the negative electrode active material and ensures stable operation of the battery during charging and discharging. Usually, during the production process of the current collector, it is necessary to test its appearance, size, surface finish and other parameters to ensure that the product parameters are qualified. In the existing technology, the current collector usually needs to be manually placed in various testing institutions for testing, which is not continuous, inefficient and not conducive to production.

[0030] Referring to Figures 1 and 2, Figure 1 is a schematic diagram of the automatic detection equipment for the negative electrode current collector of the large cylindrical battery in the embodiment, and Figure 2 is a schematic diagram of the detection device and the feeding device in the embodiment. In this example, an automatic testing device for the negative electrode current collector of a large cylindrical battery includes a feeding device 1, a testing device 2, and a discharging device 3. The feeding device has a discharge conveyor line 16 on one side. The testing device 2 is arranged adjacent to the feeding device 1 and includes a machine base 21, a first clamping mechanism 22, and a testing mechanism 23. The discharge conveyor line extends to the machine base 21. The first clamping mechanism 22 is mounted on the machine base 21 and located above the discharge conveyor line 16. The testing mechanism 23 includes a rotary conveying assembly 231 and multiple testing components 232. The rotary conveying assembly 231 and the first clamping mechanism 22 are arranged adjacent to each other on the machine base 21. The first clamping mechanism 22, multiple testing components 232, and the discharging device 3 are arranged sequentially along the conveying direction of the conveying assembly 231. The multiple testing components 232 are used to test the flatness, upper and lower surface shape, size, and thickness of the product. In practice, a cleaning machine can be placed at the front end of the feeding device 1. During operation, products are placed in batches in the tray and cleaned by the cleaning machine before being conveyed to the feeding device 1. The feeding device 1 then conveys the tray full of products to the discharge conveyor line 16, and then to the detection device 2. At this time, the first clamping mechanism 22 clamps the products in the tray sequentially to the rotary conveyor assembly 231. The rotary conveyor assembly 231 conveys the products sequentially to each detection assembly 232 to detect the flatness, upper and lower surface dimensions, and thickness of the products. After the detection is completed, the products are collected by the unloading device 3 to complete the fully automatic detection of the products in the collection tray and improve production efficiency.

[0031] Referring to Figure 3 and reviewing Figures 1 and 2, Figure 3 is a schematic diagram of the feeding device structure in the embodiment. Specifically, the feeding device 1 also includes a frame 11, a first feeding conveyor line 12, a second feeding conveyor line 13, a first material tray gripper mechanism 14, and a feeding elevator 15. The first feeding conveyor line 12 and the second feeding conveyor line 13 are both arranged in the frame 11 along the length direction and are arranged parallel to each other. The feeding elevator 15 is located at one end of the frame 11, and its conveying path passes through the first feeding conveyor line 12 and the second feeding conveyor line 13 respectively. The feeding elevator 15 is equipped with a third feeding conveyor line 151. The discharge conveyor line 16 is located at the other end of the second feeding conveyor line 13 and is arranged perpendicular to the second feeding conveyor line 13. Its other end extends to the machine base 21. The first material tray gripper mechanism 14 is located above the second feeding conveyor line 13 and the discharge conveyor line 16 and is fixed on the frame 11. The first material tray gripper mechanism 14 can grip the material tray on the second feeding conveyor line 13 and transfer it to the discharge conveyor line 16. During operation, the washing machine conveys the material tray to the first feeding conveyor line 12. Simultaneously, the feeding elevator 15 raises the third feeding conveyor line 151 to the same horizontal level as the first feeding conveyor line 12. At this point, the material tray is conveyed from the first conveyor line 12 to the third conveyor line 151. Subsequently, the feeding elevator 151 lowers the third feeding conveyor line 151 to the same horizontal level as the second feeding conveyor line 152. The third feeding conveyor line 151 then starts conveying the material tray to the second feeding conveyor line 13. The second feeding conveyor line 13 then conveys the material tray to the gripper mechanism 14 near the first material tray. The gripper mechanism 14 then clamps the material tray and moves it to the discharge conveyor line 16. The discharge conveyor line 16 then conveys the material tray to the first clamping mechanism 22 for product clamping. In this example, the first feeding conveyor line 12, the second feeding conveyor line 13, the third feeding conveyor line 151, and the discharge conveyor line 16 all use roller conveyors, and the feeding elevator 15 uses a chain elevator.

[0032] Furthermore, the feeding device 1 also includes an empty tray return mechanism 17. The empty tray return mechanism 17 includes a return elevator 171, a first return conveyor line 172, and a second return conveyor line 173. The machine base 1 has a return port 211 on its upper surface. The return port 211 is located at the end of the discharge conveyor line 16. The return elevator 171 is located at the return port 211. The first return conveyor line 172 is located at the bottom of the frame 11 and is parallel to the first feeding conveyor line 12 and the second feeding conveyor line 13. The second return conveyor line 173 is located inside the machine base 21 and is parallel to the discharge conveyor line 16. One end of the second return conveyor line 173 is close to the return elevator 171, and the other end is close to the first return conveyor line 172. The return elevator 171 has a third return conveyor line 174. One end of the third return conveyor line 174 is close to one end of the first return conveyor line 171. After the first clamping mechanism 22 clamps the product from the end tray of the discharge conveyor line 16, the discharge conveyor line 16 conveys the tray toward the return elevator 171. Simultaneously, the return elevator 171 raises the third return conveyor line 174 to the same horizontal level as the discharge conveyor line 16. At this point, the return elevator 171 can convey the empty tray to the return elevator 171 for recycling. Then, the return elevator 171 lowers by one tray height, waiting for the discharge conveyor line 16 to convey the next empty tray. It can be understood that when the number of trays on the return elevator 171 reaches a specified number, they are conveyed by the third return conveyor line 174 to the first return conveyor line 172. Subsequently, the trays are sequentially conveyed through the first return conveyor line 172 and the second return conveyor line 173 to the outside of the frame 1. In a specific implementation, a recycling elevator 175 can also be installed at one end of the frame 11 to convey the empty trays to the same horizontal level as the first return conveyor line 172, facilitating recycling by the washing machine. In this example, the first return conveyor line 172, the second return conveyor line 173 and the third return conveyor line 174 also use roller conveyors, and the return elevator 171 uses a screw jack.

[0033] In another embodiment, the testing device 2 and the unloading device 3 can be set in two sets. Correspondingly, two sets of second feeding conveyor lines 13, first material tray gripper mechanism 14 and unloading conveyor lines 16 are symmetrically arranged in the middle layer of the frame 1. At the same time, feeding elevators 15 are respectively set at both ends of the frame 1 so that the material trays on the first conveyor line 12 can be transported to the two sets of second conveyor lines 13 through the feeding elevators 15 at both ends, thereby supplying materials to the two sets of testing devices 2 and further improving testing efficiency.

[0034] Referring to Figure 4 and reviewing Figures 1-2, Figure 4 is a schematic diagram of the structure of the first gripping mechanism in the embodiment. Furthermore, the first gripping mechanism 22 includes a first gripper portion 221, a correction portion 222, and a second gripper portion 223. The correction portion 222 is located on the side of the discharge conveyor line 16 near the detection mechanism 23 and is arranged parallel to each other. The first gripper portion 221 is mounted above the correction portion 222 and the discharge conveyor line 16, and is perpendicular to the discharge conveyor line 16. One end of the correction portion 222 is located directly below the first gripper portion 221, and the other end extends from the side of the first gripper portion 221 away from the feeding device 1 to the outside of the first gripper portion 221. The second gripper portion 223 is located above the correction portion 222 and one end of the rotary conveyor assembly 231, and is arranged perpendicular to the correction portion 222. During operation, the first gripper 221 picks up the product from the tray and moves it to the correction part 222. The correction part 222 adjusts the product angle to ensure that the angle of each product is consistent. Then, the second gripper 221 picks it up and moves it to the testing mechanism 23.

[0035] Specifically, the first gripper part 221 includes two sets of first gripper assemblies 2211, which are arranged parallel to each other. One end of the correction part 222 is located between the two sets of first gripper assemblies 2211, and the other end extends out from under the set of gripper assemblies 2211 that is away from the feeding device 1. Each set of first gripper assemblies 2211 includes a first lateral displacement assembly 22111, a first gripper lifting assembly 22112, and a first gripper 22113. The first lateral displacement assemblies 22111 are arranged parallel to each other, and the first gripper lifting assemblies 22112 of the two sets of first grippers 2211 are arranged facing each other. The first gripper 2211 is located on the first gripper lifting assembly 22112. Each first gripper 2211 has multiple first gripping parts 221131, and the multiple first gripping parts 221131 are arranged in a direction parallel to the correction part 222. Understandably, during operation, the two sets of first gripper assemblies 2211 alternately grip the product, thereby further improving inspection efficiency. In this example, both the first lateral displacement assembly 22111 and the first gripper lifting assembly 22112 adopt a lead screw linear drive module, and the first gripping component 221131 adopts a parallel pneumatic gripper. In this example, the structure and principle of the second gripper part 223 are the same as those of the first gripper part 221, and will not be described again here.

[0036] Preferably, the first gripper portion 221 further includes a flipping assembly 2212, which includes a flipping plate 22121 mechanism and a flipping drive 22122. The flipping drive 22122 is fixed to the first gripper lifting assembly 22112, and the flipping plate 22121 is mounted on the drive end of the flipping drive 22122. Multiple first gripping elements 221131 are arranged on the flipping plate 22121. In this example, the flipping drive 22122 is a servo motor. It is understood that since the product is usually placed vertically in the tray for easy cleaning, after the first gripping elements 221131 grip the product, the flipping assembly 2212 flips the product to a horizontal state, making it easier to place the product in the correction part 222.

[0037] Referring to Figure 5 and reviewing Figures 1-2, Figure 5 is a schematic diagram of the correction section structure in the embodiment. The correction section 222 includes two sets of correction components 2221, both sets of which are arranged parallel to the discharge conveyor line 16. Each set of correction components 2221 includes a correction displacement component 22211 and multiple correction bearing components 22212. One end of the correction displacement component 22211 is located between the two sets of first gripper components 2211, and the other end protrudes below one set of gripper components 2211. The multiple correction bearing components 22212 extend along the correction displacement component 22211. 11 are arranged along the length direction on the correction displacement assembly 22211. Each correction bearing assembly 22212 includes a correction rotation drive 222121 and a correction rotation table 222122. The drive end of the correction rotation drive 222121 is vertically upward, and the correction rotation table 222122 is located at its drive end. When the first gripper 22113 is located directly above the correction rotation table 222122, the correction rotation table 222122 is directly opposite the first gripper 221131. In this example, the correction displacement assembly 22211 uses a lead screw linear drive module, and the correction rotation drive 222121 uses a servo motor. In specific implementation, a correction camera 2222 is set above the correction component 2221. The correction camera 2222 faces the correction support component 22212. During operation, when the product is placed on the correction rotary table 222122, after being detected by the correction camera 2222, the correction rotation drive component 222121 drives the correction rotary table 222122 to rotate according to the system instruction, so that the product angle on each correction rotary table 222122 is consistent, thereby improving the consistency of detection and ensuring the detection quality. After the correction is completed, the correction displacement component 22211 transports the correction support component 22212 to the second gripper part 223. At this time, the second gripper part 223 can clamp the product to the rotary conveyor component 231.

[0038] Referring to Figure 6 and reviewing Figures 1-2, Figure 6 is a schematic diagram of the detection mechanism structure in the embodiment. Further, the rotary conveying assembly 231 includes a rotary conveyor 2311 and multiple support plates 2312. The multiple support plates 2312 are circumferentially mounted on the rotary conveyor 2311, and the movement path of each support plate 2312 passes below the movement path of the second gripper portion 223. The support plates 2312 are made of transparent material. Multiple detection components 232 sequentially include multiple sets of surface detection components 2321 and thickness detection components 2322 along the conveying direction of the support plate 2312. The surface detection component 2321 includes a first support 23211 and two surface detection elements 23212. The two surface detection elements 23212 are arranged facing each other along the height direction of the first support 23211. The movement path of the support plate 2312 passes between the two surface detection elements 23212. The thickness detection component 2322 includes three sets of thickness detection elements 23221. Two sets of thickness detection elements 23221 are arranged adjacently and horizontally facing the outside of the movement path of the support plate 2312. The other set of thickness detection elements 23221 is located inside the rotary conveyor 2311. The three sets of thickness detection elements 23221 are distributed in an equilateral triangle. Understandably, since the support plate 2312 is transparent, the two surface inspection components 23212 can simultaneously inspect the upper and lower surfaces of the product, thereby improving inspection efficiency. Specifically, the surface inspection component 2321 is used to inspect the flatness, shape, and dimensional accuracy of the upper and lower surfaces of the product, while the thickness inspection component 2322 is used to inspect the thickness of the product's sidewalls, ensuring more accurate sidewall thickness measurement. In this example, the rotary conveyor 2311 uses a magnetic levitation motor conveyor, both the surface inspection component 23212 and the thickness inspection component 23221 are industrial cameras, and the support plate 2312 is made of transparent glass.

[0039] Referring to Figures 7-9 and reviewing Figures 1-2, Figure 7 is a schematic diagram of the material sorting mechanism in the embodiment, Figure 8 is a schematic diagram of the finished product collection and storage section in the embodiment, and Figure 9 is a schematic diagram of the defective product collection and storage section in the embodiment. Specifically, the material feeding device 3 further includes a material sorting mechanism 31 and two sets of collection mechanisms 32. The material sorting mechanism 31 is located between the thickness detection component 2322 and the second gripper portion 223. The two sets of collection mechanisms 32 are respectively located on both sides of the end of the machine base 1 away from the feeding device 1. The material sorting mechanism 31 includes two adjacent sorting sections 311, which respectively clamp the finished product and defective product of the bearing plate 2312 to the two sets of collection mechanisms 32.

[0040] Both sorting units 311 include sorting gripper assemblies 3111 and multi-group sorting displacement assemblies 3112. One end of the sorting gripper assembly 3111 is mounted above the movement path of the support plate 2312, and the other end rotates and extends away from 2311. The multi-group sorting displacement assemblies 3112 are arranged parallel to each other on the machine base 21, with one end located below the sorting gripper assembly 3111, and the other ends of the sorting displacement assemblies 3112 of the two sorting units 311 extending away from each other. The two sorting units 311 are used for collecting good and defective products, respectively. The structure and principle of the sorting gripper assembly 3111 are the same as those of the first gripper unit 221, and the structure and principle of the sorting displacement assembly 3112 are the same as those of the correction displacement assembly 2221. The difference is that the sorting displacement assembly 3112 also has multiple sets of support platforms 31121.

[0041] Furthermore, both sets of collection mechanisms 32 include a collection gripping section 321 and a collection storage section 322. The collection gripping section 321 is adjacent to one end of the sorting displacement assembly 3112 of the two sets of sorting sections 311. The collection storage section 322 of the two sets of collection mechanisms 32 is adjacent to one end of the machine base 21 away from the feeding device 1. The collection gripping section 321 grips the products of the sorting displacement assembly 3112 and collects them in the collection mechanism 32. In this example, the collection gripping section 321 is an industrial robot.

[0042] Specifically, the collection and storage sections 322 of the two sets of collection mechanisms 32 are a finished product collection and storage section 322a and a defective product collection and storage section 322b, respectively. The finished product collection section 322a includes two sets of finished product tray lifting components 322a1 and a finished product tray clamping component 322a2. The two sets of finished product tray lifting components 322a1 are arranged adjacent to each other below the machine base 21. They are an empty tray replenishment lifting component 322a11 and a finished product collection lifting component 322a12, respectively. The machine base 211 is provided with a finished product tray replenishment port 212 corresponding to the two components. The finished product tray clamping component 322a2 is mounted on the finished product tray replenishment port 212. In use, the worker stacks the empty finished product trays on one of the empty tray sets. Inside the replenishment component 322a11, the corresponding collection gripper 321 picks up the finished product from the sorting displacement component 3112 and places it into the finished product tray. When the top finished product tray is full, the finished product tray gripper 322a2 picks up the finished product tray and places it into the finished product collection lifting component 322a12. At the same time, the finished product collection component 322a12 descends one layer, and the empty tray replenishment lifting component 322a11 rises one layer. This cycle continues until the finished product collection lifting component 322a12 is full. At this point, the worker removes the full tray from the finished product collection component 322a12 and simultaneously replenishes the empty tray replenishment lifting component 322a11 with an empty finished product collection tray. In this example, the finished product collection lifting component 322a12 and the empty tray replenishment lifting component 322a11 are scissor lifts.

[0043] The finished product tray clamping assembly 322a2 includes two sets of finished product tray transverse moving assemblies 322a21, a finished product gripper lifting assembly 322a22, and a finished product tray gripper 322a23. The two sets of finished product tray transverse moving assemblies 322a21 are respectively located on both sides of the finished product tray replenishment port 212, and they adopt wheeled linear modules. The finished product gripper lifting assembly 322a22 is respectively driven and connected to the two sets of finished product tray transverse moving assemblies 322a21, and it is composed of linear cylinder assemblies. The finished product tray gripper 322a23 is located at the drive end of the finished product tray lifting assembly 322a22. The finished product gripper lifting assembly 322a22 drives the finished product tray gripper 322a23 to move in the vertical direction. The two sets of finished product tray transverse moving assemblies 322a21 cause the finished product tray gripper 322a23 to move above the empty tray replenishment lifting assembly 322a11 and the finished product collection lifting assembly 322a12.

[0044] Furthermore, the defective product collection and storage unit 322b includes multiple sets of defective product collection components 322b1 arranged adjacent to each other.

The platform 211 also has a defective material tray replenishment port 213, which is located at one end of the first collection and conveying line 322b11. The defective material tray elevator 322b13 is located at the defective material tray replenishment port 213, and its lower end is located at one end of the second collection and conveying line 322b12. The defective material tray clamping assembly 322b14 includes a defective material tray lateral movement assembly 322b141, a defective material tray lifting assembly 322b142, and a defective material tray gripper 322b143. The defective product tray lateral movement assembly 322b141 is located on one side of the first collection and conveying line 322b12, with one end extending to one side of the tray replenishment port 213. The defective product tray lifting assembly 322b142 is driven by the defective product tray lateral movement assembly 322b141. The defective product tray gripper 322b143 is located above the first collection and conveying line 322b11 and connected to the defective product tray lifting assembly 322b142. During operation, the defective product tray lifting assembly 322b142 drives the defective product tray gripper 322b143 to move vertically. At the same time, the defective product tray lateral movement assembly 322b141 causes the defective product tray gripper 322b143 to move above the first collection and conveying line 322b11 and the defective product replenishment port 213. In use, the worker stacks empty defective product trays on the first collection and conveying line 322b12. Inside 12, at this time, the first collection conveyor line 322b12 transports the empty defective product tray to the tray replenishment port 213. The defective product tray gripper 322b143 then clamps the empty defective product tray onto the defective product tray lifting assembly 322b142. Correspondingly, the collection gripper 321 clamps the defective products into the empty defective product tray of the defective product tray lifting assembly 322b142. When an empty defective product tray is full, the defective product tray lifting assembly 322b142 descends one layer. At the same time, an empty defective product tray is replenished to the defective product tray lifting assembly 322b142 according to the above steps. This cycle continues until the defective product tray lifting assembly 322b142 descends and passes through the second collection conveyor line 322b13. At this time, the full trays are stacked on the second collection conveyor line 322b13 and transported out of the machine, where workers can then remove them. Among them, the first collection and conveying line 322b11 and the second collection and conveying line 322b12 adopt synchronous belt conveyors, the defective material tray elevator 322b13 adopts a pulley elevator, the defective material tray transverse moving assembly 322b141 adopts a pulley linear module, and the defective material tray lifting assembly 322b142 adopts a pneumatic linear module.In practice, the multiple defective product collection components 322b1 can be used to collect different types of defective products, such as those with unqualified thickness or unqualified upper and lower surface dimensions, which is convenient to use.

[0045] In summary, in this example, the cooperation of the feeding device, the detection device, and the unloading device enables fully automated continuous detection of the flatness, upper and lower surface dimensions, and thickness of the negative electrode collector, effectively improving production efficiency.
