Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and in particular to a battery processing production line. Background Art

[0002] A battery consists of a cell, a circuit board, and a packaging box. The battery consists of a battery body and a nickel sheet extending from the end of the cell body. During battery processing, the nickel sheet must be welded to the circuit board. The circuit board is then appropriately bent and placed into the packaging box, which has an upper opening. The upper surface of the packaging box is then sealed and tightly wrapped with Mylar film before being sent to an outer packaging device for packaging. Existing battery processing production lines cannot directly connect the various processes, requiring multiple operators to load and unload materials between processes.

[0092] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0094] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0095] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0096] like Figure 1As shown, the battery cell 910 includes a battery cell body 911 and a nickel sheet 912 protruding from the battery cell body 911, and a welding area 921 is provided on the circuit board 920. Figure 2 As shown, the cover box 930 is a box body with an upper opening. During the battery production process, the nickel sheet 912 of the battery cell 910 needs to be welded to the welding area 921 on the circuit board 920 to form a battery assembly. Then the circuit board 920 is bent to form a compact structure of the battery assembly, and then placed in the cover box 930. At this time, the battery assembly is formed as shown in FIG. Figure 2 Finally, as shown in the semi-finished product Figure 3 As shown, the upper surface of the covering box 930 is covered with a Mylar film 940 , and the suspended edge of the Mylar film 940 is folded downward and adhered to the side surface of the covering box 930 .

[0097] In this regard, this embodiment provides a battery processing production line, which can be used in the above-mentioned battery production process. Figure 4 and Figure 5As shown, the battery processing production line includes a rack and the following components arranged on the rack: a cell loading device 100, a first transfer mechanism 810, a cutting device 200, a circuit board loading device 300, a second transfer mechanism 820, a third transfer mechanism 830, a welding device 400, a fourth transfer mechanism 840, a bending mechanism 500, a conveying mechanism 600, a fifth transfer mechanism 850, and an edge wrapping device 700. The rack can be composed of four or more platforms, which facilitates the handling and assembly of the production line. Specifically, the cell loading device 100 is used to store and transport a first tray, each of which is loaded with a plurality of cells. The first transfer mechanism 810 can grab the cells from the cell loading device 100 and place them in the cutting device 200, which can cut and correct the nickel sheets of the cells. The circuit board loading device 300 can store and transport a second tray, which carries multiple circuit boards. The third transfer mechanism 830 can grab the circuit boards from the circuit board loading device 300 and place them into the welding device 400. The second transfer mechanism 820 can place the battery cells from the cutting device 200 into the welding device 400, so that the nickel sheets of the battery cells overlap the corresponding welding areas of the circuit boards. The welding device 400 can weld the circuit boards and nickel sheets together to form a battery assembly. The fourth transfer mechanism 840 can place the battery assembly from the welding device 400 into the bending mechanism 500, which bends the circuit boards of the battery assembly. The fourth transfer mechanism 840 can also place the bent battery assembly into the conveying mechanism 600. An operator can then load the battery assembly conveyed by the conveying mechanism 600 into a packaging box to form a semi-finished product, and then return the semi-finished product to the conveying mechanism 600 for transportation. The fifth transfer mechanism 850 can place the semi-finished product in the conveying mechanism 600 into the edge wrapping device 700. The edge wrapping device 700 can place the Mylar film on the semi-finished product and wrap the Mylar film on the semi-finished product, thereby completing the processing of the battery.

[0098] The battery processing production line of this embodiment is equipped with a battery cell loading device 100, a first transfer mechanism 810, a cutting device 200, a circuit board loading device 300, a second transfer mechanism 820, a third transfer mechanism 830, a welding device 400, a fourth transfer mechanism 840, a bending mechanism 500, a conveying mechanism 600, a fifth transfer mechanism 850, and an edge wrapping device 700. It can automatically complete battery cell loading, nickel sheet cutting, circuit board loading, welding of circuit boards and battery cells, bending of circuit boards, and wrapping of wrapping boxes. In addition, each process is automatically connected with each other, with a high degree of automation, which improves work efficiency and reduces labor costs.

[0099] like Figure 6 and Figure 7As shown, the frame includes a first platform 950, and the battery cell loading device 100 is arranged on the first platform 950. The battery cell loading device 100 includes a first straight conveyor line 11 and a first storage mechanism 12, a limiting mechanism 13 and a second storage mechanism 14 which are sequentially arranged above the first conveyor line. Among them: the first storage mechanism 12 can carry a fully loaded first pallet stacked in the up and down directions, and the first storage mechanism 12 can also place the fully loaded first pallet on the bottom layer on the first straight conveyor line 11. Then, the first straight conveyor line 11 can transport the first pallet to the limiting mechanism 13, and the limiting mechanism 13 fixes the position of the first pallet, and the first transfer mechanism 810 can grab the battery cells one by one from the first pallet at the limiting mechanism 13. When all the battery cells on the first tray at the limiting mechanism 13 are removed, the limiting mechanism 13 releases the limit on the first tray, and the first straight conveyor line 11 conveys the empty first tray to the bottom of the second storage mechanism 14. At this time, the second storage mechanism 14 removes the first tray from the first straight conveyor line 11, and so on. The second storage mechanism 14 gradually stacks multiple empty first trays in the up and down directions.

[0100] The battery cell loading device 100 of this embodiment can automatically realize the one-by-one delivery of fully loaded trays and the stacking of empty trays, so the operator can complete the loading of multiple first trays and the removal of multiple first trays at one time, thereby improving the loading efficiency and reducing labor costs. Figure 6 As shown, in this embodiment, the battery cell loading device 100 includes two first storage mechanisms 12, which are arranged side by side along the extension direction of the first straight conveyor line 11. By providing two first storage mechanisms 12, more first trays can be loaded at one time. Similarly, the battery cell loading device 100 includes two second storage mechanisms 14, which are arranged side by side along the extension direction of the first straight conveyor line 11. By providing two second storage mechanisms 14, more empty first trays can be stored, thereby reducing the number of operations performed by the operator. It is understandable that in other embodiments, three or more first storage mechanisms 12 and second storage mechanisms 14 can also be provided, and no specific settings are made here.

[0101] Alternatively, as Figure 6 and Figure 7 As shown, the first straight conveyor line 11 includes two sets of parallel belts 111, which can respectively support the two ends of the first tray and drive the first tray to move along the length direction of the belts 111. Figure 7As shown, the first storage mechanism 12 includes a lifting assembly 121 and two groups of clamping assemblies 122. The two groups of clamping assemblies 122 are respectively arranged on both sides of the first straight conveyor line 11 along the length direction, and the output ends of the two groups of clamping assemblies 122 can extend in a direction close to each other, so as to be located above the first straight conveyor line 11. At this time, the output ends of the two groups of clamping assemblies 122 can support multiple stacked first pallets. It should be noted that avoidance openings for the clamping assemblies 122 to extend into are respectively provided at both ends of the lower surface of the first pallet. The lifting assembly 121 is arranged at a position between the two groups of belts 111, and the output end of the lifting assembly 121 moves upward to be supported below the first pallet on the lowest layer.

[0102] like Figure 6 and Figure 7 As shown, the process of the first storage mechanism 12 placing the bottommost pallet onto the first linear conveyor line 11 is as follows: the output end of the jacking assembly 121 moves upward and supports the bottom of the bottommost first pallet; the output ends of the two sets of clamping assemblies 122 are respectively recovered to leave the stacked first pallets, at which point all the first pallets are supported on the jacking assembly 121; then the jacking assembly 121 drives all the first pallets to move downward by the height of one first pallet; then the output ends of the two sets of clamping assemblies 122 approach each other and are inserted into the avoidance opening of the first pallet of the second lower layer, at which point the two sets of clamping assemblies 122 support all the first pallets of the second lower layer and the first pallet above it; finally, the output end of the jacking assembly 121 drives the bottommost first pallet to move downward and causes the first pallet to fall onto the two sets of belts 111. In this embodiment, the jacking assembly 121 can be a structure in which a cylinder cooperates with a pallet, and the clamping assembly 122 can be a structure in which a cylinder cooperates with a clamping member. The structure and working principle of the second storage mechanism 14 are the same as those of the first storage mechanism 12 , but the operation sequence is reversed. Therefore, the detailed structure of the second storage mechanism 14 will not be described here.

[0103] like Figure 4 and Figure 8 As shown, the frame also includes a second platform 960, which is arranged in contact with the first platform 950. The first transfer mechanism 810, the cutting device 200 and the second transfer mechanism 820 are all arranged on the second platform 960. Figure 8 As shown, the second transfer mechanism 820 includes a four-axis robotic arm and a first robotic arm, wherein the four-axis robotic arm can be any existing one, and the first robotic arm can be a suction cup or other existing structure capable of clamping the battery cell, which is not specifically limited here.

[0104] like Figures 8-10As shown, the cutting device 200 includes a cutting conveyor line 21, a plurality of cutting carriers 22, a battery cell scanning mechanism 23, a battery cell shaping mechanism 24, a cutting mechanism 25, a leveling mechanism 26 and a cutting detection mechanism 27. The cutting conveyor line 21 is arranged on the second platform 960 and is annular. A plurality of cutting carriers 22 are arranged at intervals on the cutting conveyor line 21. The cutting conveyor line 21 can drive the plurality of cutting carriers 22 to move along an annular trajectory and sequentially arrive at the battery cell loading station 28, the battery cell scanning station, the battery cell shaping station, the cutting station, the leveling station, the cutting detection station and the battery cell unloading station 29. It should be noted that the above-mentioned stations all represent spatial positions and do not represent physical structures. By setting up an annular conveyor line, the automatic flow of the cutting carrier 22 can be realized, and there is no need to additionally transport the cutting carrier 22 from the battery cell unloading station 29 to the battery cell loading station 28, which further reduces the demand for manpower. Optionally, as Figure 10 As shown, the cutting conveyor line 21 includes a driving motor 211 and a conveyor belt assembly 212. The conveyor belt assembly 212 is arranged to form a circular track. Multiple cutting carriers 22 are fixed on the conveyor belt assembly 212 at intervals. The driving motor 211 can drive the conveyor belt assembly 212 to rotate, thereby driving each cutting carrier 22 to reach each workstation of the cutting device 200 in turn.

[0105] The cutting carrier 22 can limit the battery cells, wherein the battery cell body of the battery cell is limited in the cutting carrier 22, and the nickel sheet of the battery cell extends to the outside of the cutting carrier 22. The first transfer mechanism 810 can place the grabbed battery cells on the cutting carrier 22 located at the battery cell loading station 28. The battery cell scanning mechanism 23 is arranged at the battery cell scanning station, and is used to identify the QR code on the battery cell on the cutting carrier 22 rotated to the station, so as to facilitate material management. The battery cell shaping mechanism 24 is arranged at the battery cell shaping station, and the battery cell shaping mechanism 24 includes a downward pressure cylinder and a pressure head. The downward pressure cylinder drives the pressure head to move in the up and down directions toward the nickel sheet to flatten the nickel sheet of the battery cell, so that the nickel sheet is flat before cutting, thereby ensuring the accuracy of subsequent cutting. The battery cell scanning mechanism 23 includes a scanning gun that can identify the QR code on the battery cell. The cutting mechanism 25 is provided at the cutting station and is used to cut the edges of the nickel sheet so that the length of the nickel sheet reaches the required standard. The flattening mechanism 26 is provided at the flattening station and includes a downward pressure cylinder and a pressure head. The downward pressure cylinder drives the corresponding pressure head to approach the nickel sheet in the vertical direction, which can flatten the cut nickel sheet to facilitate the subsequent accurate detection of the shape and size of the cut nickel sheet. The cutting detection mechanism 27 is provided at the cutting detection station and can detect the shape of the cut nickel sheet to ensure that the nickel sheets of the battery cells flowing into the subsequent welding device 400 are all qualified.

[0106] Preferably, the cutting carrier 22 can hold at least two battery cells, and the first transfer mechanism 810, the battery cell scanning mechanism 23, the battery cell shaping mechanism 24, the cutting mechanism 25, the leveling mechanism 26, and the cutting detection mechanism 27 can all simultaneously operate on two battery cells on a cutting carrier 22 at the corresponding workstation. This greatly improves the efficiency of battery processing and increases production capacity. In this embodiment, each cutting carrier 22 can hold two battery cells. In other embodiments, each cutting carrier 22 can also hold three or more battery cells as needed, which is not specifically limited here.

[0107] Alternatively, as Figure 11 As shown, the cutting mechanism 25 includes an upper cutter die 251, a lower cutter die 252, an upper die drive assembly 253, a lower die transverse drive assembly 254, and a lower die lift drive assembly 255. The lower die transverse drive assembly 254 can drive the lower cutter die 252 to move horizontally, thereby moving the lower cutter die 252 below the nickel sheet at the cutting station. The lower die lift drive assembly 255 can drive the lower cutter die 252 to move vertically, so that the lower cutter die 252 is supported below the nickel sheet. The upper die drive assembly 253 can drive the lower cutter die 252 to move vertically to cut the nickel sheet. Optionally, in some embodiments, the lower die lift drive assembly 255 is connected to the output end of the lower die transverse drive assembly 254. In other embodiments, the lower die transverse drive assembly 254 can also be connected to the output end of the lower die lift drive assembly 255, which is not specifically limited here. Optionally, the lower die lifting drive assembly 255 and the lower die lateral drive assembly 254 can both be existing structures that can output linear motion, such as cylinders and linear modules, and are not specifically limited here. In this embodiment, two groups of cutter upper molds 251 and cutter lower molds 252 are provided to cut two battery cells on the cutting carrier 22 simultaneously. Optionally, the cutting mechanism 25 also includes a dust collection assembly, which is provided below the cutter lower mold 252. The dust collection assembly can absorb and collect waste scraps generated by cutting nickel sheets, thereby improving the cleanliness of the working environment. Specifically, the dust collection assembly can include an exhaust fan.

[0108] like Figure 12As shown, the cutting detection mechanism 27 includes a support rod 273, a straightening assembly 271 connected to the support rod 273, and a cutting detection camera 272. The straightening assembly 271 can clamp the middle of the nickel sheet located at the cutting detection station in the vertical direction to ensure that the nickel sheet to be inspected is flat. The cutting detection camera 272 is located above the straightening assembly 271 and can take pictures of the nickel sheet. The provision of the cutting detection mechanism 27 can obtain the status information of the nickel sheet after cutting, so as to facilitate the sorting of qualified and unqualified cutting cells, and prevent the unqualified cutting cells from flowing into the subsequent welding device 400. In this embodiment, the straightening assembly 271 includes a clamping cylinder 2711 and two clamps 2712. When the cutting carrier 22 moves to the cutting station, the nickel sheet is located between the two clamps 2712. At this time, the clamping cylinder 2711 drives the two clamps 2712 to move closer to each other to clamp the middle of the nickel sheet. At this time, the end of the nickel sheet is still located outside the clamp 2712, thereby ensuring that the cutting detection camera 272 can accurately obtain the image of the edge of the nickel sheet.

[0109] like Figure 8 and Figure 9 As shown, the second transfer mechanism 820 includes a second transfer assembly 821, a second manipulator 822, and a defective product conveyor line 823. The second transfer assembly 821 is capable of driving the second manipulator 822 to grab a cell from the cell unloading station 29 of the cutting device 200 and place the cell into the defective product conveyor line 823 or the welding device 400. The second transfer assembly 821 is in communication with the cutting inspection mechanism 27. Specifically, the second transfer assembly 821 is capable of obtaining information on whether the nickel sheet of the currently grabbed cell is qualified. If the currently grabbed cell is qualified, the second transfer assembly 821 places the cell into the welding device 400. If the currently grabbed cell is unqualified, the second transfer assembly 821 places the cell onto the defective product conveyor line 823, thereby facilitating the operator's recovery of the defective cells. Optionally, the second transfer assembly 821 includes a first transverse linear module 8211 and a first lifting linear module 8212. The first traversing linear module 8211 is disposed on the second platform 960, the first lifting linear module 8212 is connected to the output end of the first traversing linear module 8211, and the second manipulator 822 is connected to the output end of the first lifting linear module 8212. The coordination between the first lifting linear module 8212 and the second lifting linear module 8213 ensures that the second manipulator 822 can smoothly move between the battery cell unloading station 29, the defective product conveyor line 823, and the welding device 400. Alternatively, the second manipulator 822 may be a suction cup or other existing structure capable of gripping battery cells, which is not specifically limited herein.

[0110] like Figure 4 and Figure 13As shown, the frame also includes a third platform 970, which is abutted against the second platform 960. The circuit board loading device 300, the welding device 400, and the conveying mechanism 600 are arranged on the third platform 970. The structure of the circuit board loading device 300 is the same as that of the battery cell loading device 100, and will not be repeated here.

[0111] like Figure 13 and Figure 14 As shown, the welding device 400 includes a welding conveyor line 41, multiple welding carriers 42, a pre-welding inspection mechanism 43, a welding mechanism 44, a post-welding inspection mechanism 45, an insulating paper supply mechanism 46, an insulating paper pasting mechanism 47, a double-sided tape supply mechanism 48, and a double-sided tape pasting mechanism 49. The welding conveyor line 41 is annular and can drive multiple welding carriers 42 to move along an annular trajectory and sequentially reach the circuit board loading station 410, the battery cell fixing station 420, the pre-welding inspection station, the welding station, the post-welding inspection station, the insulating paper pasting station, the double-sided tape pasting station, and the battery assembly unloading station 430. Multiple welding carriers 42 are arranged at intervals on the welding conveyor line 41. The welding carriers 42 include battery cell fixing positions and circuit board fixing positions. The battery cell fixing positions and circuit board fixing positions are used to limit the battery cell and circuit board, respectively. After the circuit board and battery cell are placed on the welding carrier 42 in sequence, the nickel sheet of the battery cell overlaps the welding area of ​​the circuit board. By providing a circular conveyor line, the welding carrier 42 can be automatically transferred, eliminating the need to transport the welding carrier 42 from the battery assembly unloading station 430 to the circuit board loading station 410, further reducing the need for labor. In this embodiment, the general structure of the welding conveyor line 41 is the same as that of the cutting conveyor line 21 and will not be repeated here.

[0112] Preferably, the welding carriage 42 is capable of securing at least two sets of battery cells and circuit boards. The second transfer mechanism 820, the third transfer mechanism 830, the pre-weld inspection mechanism 43, and the post-weld inspection mechanism 45 are each capable of operating on the two sets of battery cells and / or circuit boards at corresponding workstations, thereby significantly improving battery processing efficiency and increasing production capacity. The welding mechanism 44, the insulating paper application mechanism 47, and the double-sided tape application mechanism 49 are each capable of sequentially operating on the two sets of battery cells and / or circuit boards at corresponding workstations.

[0113] like Figure 13 and Figure 14As shown, the third transfer mechanism 830 can grab the circuit board from the circuit board loading device 300 and place the circuit board on the welding carrier 42 located at the circuit board loading station 410. The third transfer mechanism 830 includes a four-axis robot arm and a third manipulator, wherein the four-axis robot arm can be any existing one, and the third manipulator can be a suction cup or other existing structure capable of clamping the battery cell, which is not specifically limited here. The second transfer mechanism 820 places the qualified battery cells grabbed from the battery cell unloading station 29 on the welding carrier 42 of the battery cell fixing station 420. At this time, the welding carrier 42 at the battery cell fixing station 420 has a circuit board and a battery cell, and the nickel sheet of the battery cell is overlapped on the welding area of ​​the circuit board. As shown Figure 15 As shown, the pre-welding detection mechanism 43 is arranged at the pre-welding detection station and is used to detect the relative position between the nickel sheet of the battery cell and the welding area of ​​the circuit board on the welding carrier 42. The welding mechanism 44 is arranged at the welding station and can adjust the welding position according to the detection results of the pre-welding detection mechanism 43. Through the cooperation of the pre-welding detection mechanism 43 and the welding mechanism 44, it is possible to ensure that the welding position matches the current relative position between the nickel sheet and the circuit board, thereby avoiding the situation of insufficient welding and cold welding, and improving the connection reliability between the battery cell and the circuit board. The post-welding detection mechanism 45 is arranged at the post-welding detection station and can detect the welding results to further confirm whether the welding meets the requirements. The insulating paper supply mechanism 46 is arranged on the third platform 970 and can supply insulating paper. The insulating paper pasting mechanism 47 is arranged at the insulating paper pasting station and is used to grab insulating paper at the insulating paper supply mechanism 46 and paste the insulating paper on the nickel sheet, thereby providing insulation protection for the connection position between the battery cell and the circuit board. It is understandable that the insulating paper supply mechanism 46 and the insulating paper pasting mechanism 47 are both existing structures and will not be described in detail here. The double-sided tape supply mechanism 48 is provided on the third platform 970 and can be used for double-sided tape. The double-sided tape pasting mechanism 49 is provided at the double-sided tape pasting station. The double-sided tape pasting mechanism 49 can grab the double-sided tape from the double-sided tape supply mechanism 48 and paste the double-sided tape on the upper surface of the battery cell located at the double-sided tape pasting station. The double-sided tape is used to bond and fix with the covering box in subsequent steps. The double-sided tape supply mechanism 48 and the double-sided tape pasting mechanism 49 are both existing mechanisms and will not be described in detail here.

[0114] like Figure 15 and Figure 16As shown, the pre-weld inspection mechanism 43 includes a first bracket 432 and a pre-weld inspection camera 431. The first bracket 432 is fixed to the third platform 970. The pre-weld inspection camera 431 is fixed to the first bracket 432. The pre-weld inspection camera 431 is used to take pictures of the battery cells and circuit boards on the welding carrier 42, thereby obtaining the relative position of the nickel sheet on the battery cells and the corresponding welding area of ​​the circuit board. In this embodiment, the pre-weld inspection mechanism 43 includes two pre-weld inspection cameras 431, both of which are mounted on the first bracket 432. Each pre-weld inspection camera 431 takes pictures of a group of battery cells and circuit boards, thereby improving the inspection efficiency of the pre-weld inspection mechanism 43. In other embodiments, the pre-weld inspection mechanism 43 can also be provided with a camera with a larger viewing angle, as long as it can meet the requirements of photographing two groups of battery cells and circuit boards.

[0115] like Figure 15 and Figure 17 As shown, the welding mechanism 44 includes a second bracket 444, an adjustment assembly 442, and a laser emitter 443. The second bracket 444 is fixed to the third platform 970. The adjustment assembly 442 and the laser emitter 443 are both mounted on the second bracket 444. The adjustment assembly 442 is in communication with the pre-weld inspection mechanism 43 and is capable of adjusting the refraction direction of the laser beam emitted by the laser emitter 443. By adjusting the refraction direction of the laser beam emitted by the laser emitter 443, the adjustment assembly 442 can adjust the specific location of the laser beam on the welding area of ​​the circuit board where the laser beam ultimately lands, thereby adjusting the welding position. Optionally, the adjustment assembly 442 can be a galvanometer with higher adjustment accuracy. Galvanometers are a mature technology in the existing market, and their specific structure and operating principle are not described in detail here. It is understood that the adjustment range of the laser beam's welding position by a single galvanometer covers two groups of battery cells and circuit boards on the same welding carrier 42. Therefore, only a single laser emitter 443 can be provided to achieve welding of both groups of battery cells and circuit boards, reducing the manufacturing cost of the production line.

[0116] Preferably, if Figure 17 As shown, welding mechanism 44 also includes a height adjustment assembly 445, which is mounted on second bracket 444. Adjustment assembly 442 and laser emitter 443 are both mounted on the output end of height adjustment assembly 445. Height adjustment assembly 445 can drive adjustment assembly 442 and laser emitter 443 to move in an up-and-down direction. By providing height adjustment assembly 445, the height of laser emitter 443 and adjustment assembly 442 can be adjusted, thereby adjusting the coverage of the laser beam emitted by laser emitter 443 to meet the welding requirements of circuit boards or battery cells of different specifications. Specifically, height adjustment assembly 445 can be a linear module or other existing mechanism capable of outputting linear motion, which is not specifically limited here.

[0117] Preferably, if Figure 17 As shown, the welding mechanism 44 also includes a first pressing claw assembly 441 and a second pressing claw assembly 446. The first pressing claw assembly 441 includes a first pressing claw body 4411 and a first pressing claw driving source 4412. The first pressing claw driving source 4412 is connected to the third platform 970. The first pressing claw body 4411 is connected to the output end of the first pressing claw driving source 4412. The first pressing claw driving source 4412 can drive the first pressing claw body 4411 to move in the up and down direction to press down the core. The second pressing claw assembly 446 includes a second pressing claw body 4461 and a second pressing claw driving source 4462. The second pressing claw driving source 4462 is connected to the third platform 970. The second pressing claw body 4461 is connected to the output end of the second pressing claw driving source 4462. The second pressing claw driving source 4462 can drive the second pressing claw body 4461 to move in the up and down direction to press down the circuit board. During the welding process, the positions of the battery cell and the circuit board can be locked respectively by the first pressure claw assembly 441 and the second pressure claw assembly 446, thereby avoiding the relative position of the nickel sheet and the welding area from shifting during the welding process, thereby ensuring the accuracy of the welding position. In the present embodiment, the welding mechanism 44 includes two first pressure claw assemblies 441, and each first pressure claw assembly 441 can correspond to the nickel sheets of two batteries in a welding carrier 42. Optionally, the first pressure claw drive source 4412 can be a cylinder or a linear module, which is not specifically limited here. Optionally, the second pressure claw drive source 4462 can be a cylinder or a linear module, which is not specifically limited here. Optionally, the welding mechanism 44 includes a second pressure claw assembly 446, which can simultaneously press the two circuit boards on the welding carrier 42. Optionally, the second pressure claw drive source 4462 can be a cylinder or a linear module, which is not specifically limited here.

[0118] like Figure 15 and Figure 18As shown, the post-weld inspection mechanism 45 includes a third bracket 453 and a post-weld inspection camera 451. The third bracket 453 is fixed to the third platform 970, and the post-weld inspection camera 451 is connected to the third bracket 453. The post-weld inspection camera 451 can take pictures of the battery cells and circuit boards on the welding carrier 42 located at the post-weld inspection station, thereby determining whether the welding mechanism 44 has reliably welded the battery cells and corresponding circuit boards. In some embodiments, detecting two or more complete solder joints on a nickel sheet indicates a satisfactory weld. Of course, in other embodiments, different welding acceptance standards can be determined based on the type of battery cells or circuit boards being welded. In this embodiment, the post-weld inspection mechanism 45 includes two post-weld inspection cameras 451, both mounted on the third bracket 453. Each post-weld inspection camera 451 takes pictures of a corresponding group of battery cells and circuit boards, thereby improving the inspection efficiency of the post-weld inspection mechanism 45. In other embodiments, the post-weld inspection mechanism 45 can also be equipped with a camera with a larger viewing angle, as long as it can capture two groups of battery cells and circuit boards.

[0119] Preferably, if Figure 18 As shown, the post-weld inspection mechanism 45 also includes a pre-stressing assembly 452, which includes a pre-stressing member 4521 and a pre-stressing drive source 4522. The pre-stressing drive source 4522 is connected to the third platform 970, and the pre-stressing member 4521 is connected to the output end of the pre-stressing drive source 4522. The pre-stressing drive source 4522 can drive the pre-stressing member 4521 to move in the up and down directions to press the circuit board located at the post-weld inspection station onto the welding carrier 42, thereby ensuring that the nickel sheet and the circuit board are in a flat state during inspection by the post-weld inspection camera 451, thereby ensuring the accuracy of the inspection results. In this embodiment, the pre-stressing drive source 4522 can be a linear module or a cylinder, and the pre-stressing member 4521 is a plate-shaped member. When the pre-stressing member 4521 is pressed onto the circuit board, the pre-stressing member 4521 can avoid the welding area, thereby ensuring that the post-weld inspection camera 451 can accurately capture the welding position.

[0120] like Figure 13 and Figure 19 As shown, the fourth transfer mechanism 840 can grab the battery assembly from the battery assembly unloading station 430 of the welding device 400, and place the battery assembly in the bending mechanism 500 for bending, so that the circuit board originally parallel to the upper surface of the battery is bent to be parallel to the side surface of the battery (that is, the circuit board is bent 90 degrees).

[0121] like Figure 14 、 Figure 20 and Figure 21As shown, the bending mechanism 500 includes a transverse movement assembly 51, a propulsion assembly 55, a bending carrier 52, a bending and pressing assembly 53, and a bending assembly 54. The transverse movement assembly 51 is mounted on the third platform 970, the propulsion assembly 55 is connected to the output end of the transverse movement assembly 51, and the bending carrier 52 is connected to the output end of the propulsion assembly 55. The bending carrier 52 is used to support the battery assembly. The transverse movement assembly 51 can output linear motion in a first horizontal direction, and the propulsion assembly 55 can output linear motion in a second horizontal direction, with the first horizontal direction being perpendicular to the second horizontal direction. The transverse movement assembly 51 and the propulsion assembly 55 cooperate to drive the bending carrier 52 to move between the loading and unloading station and the bending station. The fourth transfer mechanism 840 can grab battery assemblies from the battery assembly unloading station 430 and place them on the bending carrier 52 located in the loading and unloading station. The bending and pressing assembly 53 is mounted above the bending station and can output vertical motion to press down on the end of the circuit board connected to the battery cell. The bending assembly 54 includes a bending drive source 541 and a bending plate 542. The bending drive source 541 can drive the bending plate 542 to rotate about a horizontal axis, so that the bending plate 542 bends at least a portion of the circuit board located in the horizontal plane to a vertical plane. It should be noted that the initial bending position of the circuit board can be determined by adjusting the position at which the bending pressure assembly 53 presses down on the circuit board. In this embodiment, both the traverse assembly 51 and the propulsion assembly 55 can be linear modules. The configuration of the propulsion assembly 55 can adjust the relative position of the battery assembly and the bending pressure assembly 53, thereby adjusting the specific position at which the bending pressure assembly 53 presses on the battery assembly. The bending pressure assembly 53 includes a cylinder and a pressure bar. The cylinder drives the pressure bar to move up and down, thereby pressing down on the circuit board. The bending drive source 541 can be a motor. The bending plate 542 is rotatably fixed to the third platform 970 via a horizontally extending shaft. When the motor drives the shaft to rotate, the bending plate 542 rotates about the shaft and pushes the circuit board to bend. Preferably, in this embodiment, the battery processing line includes two bending mechanisms 500, which are arranged side by side. The fourth transfer mechanism 840 can simultaneously place battery assemblies on the bending carriers 52 on the two bending mechanisms 500, thereby improving production efficiency. Preferably, each bending carrier 52 is provided with two placement positions, each position being capable of placing a battery assembly. This enables the bending assembly 54 to simultaneously bend two battery assemblies on the same bending carrier 52, further improving production efficiency.

[0122] like Figure 19As shown, the fourth transfer mechanism 840 includes a second transverse linear module 841, a second elevating linear module 842, and a fourth manipulator 843.

The second elevating linear module 842 is connected to the output end of the second transverse linear module 841 and can output vertical linear motion. The fourth manipulator 843 is connected to the output end of the second elevating linear module 842. The second transverse linear module 841 and the second elevating linear module 842 cooperate to enable the fourth manipulator 843 to move between the battery assembly unloading station 430 of the welding device 400, the loading and unloading stations of the bending mechanism 500, and the conveying mechanism 600, thereby completing the placement of battery assemblies from the battery assembly unloading station 430 into the bending mechanism 500 and placing the bent battery assemblies in the bending mechanism 500 into the conveying mechanism 600. The fourth manipulator 843 may be a suction cup or other existing structure capable of clamping a battery cell, which is not specifically limited here.

[0123] like Figure 4 、 Figure 14 and Figure 22 As shown, the conveying mechanism 600 includes a second linear conveyor line 61 and a third linear conveyor line 62, which are arranged in parallel. The fourth transfer mechanism 840 can place the bent battery cell assemblies on the second linear conveyor line 61. The operator can then take the battery cell assemblies from the second linear conveyor line 61, then place the battery cell assemblies into a wrapping box to form a semi-finished product. Finally, the semi-finished product is placed on the third linear conveyor line 62, which transports the semi-finished product to the hemming device 700 for operation. Optionally, both the second linear conveyor line 61 and the third linear conveyor line 62 can be belt conveyors.

[0124] like Figure 22 and Figure 23As shown, the frame also includes a fourth platform 980, and the fourth platform 980 is in contact with the third platform 970. The edge wrapping device 700 is arranged on the fourth platform 980. Specifically, the edge wrapping device 700 includes an edge wrapping conveyor line 71, multiple edge wrapping carriers 72, a two-dimensional barcode feeding mechanism 73, a two-dimensional barcode pasting mechanism 74, a barcode binding mechanism 75, a Mylar film feeding mechanism 76, a Mylar film pasting mechanism 77 and an edge wrapping mechanism 78. Among them, the edge wrapping conveyor line 71 is annular, and multiple edge wrapping carriers 72 are arranged at intervals on the edge wrapping conveyor line 71. The edge wrapping conveyor line 71 can drive the edge wrapping carriers 72 to reach the semi-finished product loading station 79, the two-dimensional barcode pasting station, the barcode binding station, the Mylar film pasting station, the edge wrapping station, and the unloading station 710 in sequence. By providing a circular welding conveyor line 41, the hemming carrier 72 can be automatically transferred, eliminating the need to transport the hemming carrier 72 from the unloading station 710 to the semi-finished product loading station 79, further reducing the need for labor. In this embodiment, the general structure of the hemming conveyor line 71 is the same as that of the cutting conveyor line 21 and will not be repeated here.

[0125] Preferably, the edging carrier 72 can fix at least two semi-finished products, and the two-dimensional barcode sticking mechanism 74, the barcode binding mechanism 75, the Mylar film sticking mechanism 77 and the edging mechanism 78 can respectively operate on at least two semi-finished products on the edging carrier 72 at the corresponding work station, thereby improving the working efficiency.

[0126] like Figure 23 As shown, the fifth transfer mechanism 850 can place the semi-finished product on the conveying mechanism 600 on the edging carrier 72 located at the semi-finished product loading station 79. Specifically, the fifth transfer mechanism 850 includes a four-axis robotic arm and a fifth manipulator. The four-axis robotic arm can drive the fifth manipulator to move. The four-axis robotic arm can be any existing one, and the fifth manipulator can be a suction cup or other existing structure that can clamp the battery cell, which is not specifically limited here. The two-dimensional barcode feeding mechanism 73 is arranged on the fourth platform 980, and the two-dimensional barcode pasting mechanism 74 is arranged at the two-dimensional barcode pasting station. The two-dimensional barcode pasting mechanism 74 can grab the two-dimensional barcode from the two-dimensional barcode feeding mechanism 73 and paste it on the semi-finished product at the corresponding station, thereby realizing the marking of the semi-finished product. The two-dimensional barcode pasting mechanism 74 and the two-dimensional barcode feeding mechanism 73 are both existing mature equipment and will not be described in detail here. The barcode binding mechanism 75 is arranged at the barcode binding station and can realize the binding of the two-dimensional barcode with the information of the corresponding semi-finished product to facilitate subsequent logistics management. The Mylar film feeding mechanism 76 is arranged on the fourth platform 980, and the Mylar film pasting mechanism 77 is arranged at the Mylar film pasting station. The Mylar film pasting mechanism 77 can grab the Mylar film from the Mylar film feeding mechanism 76 and cover the semi-finished product at the corresponding station. Figure 4As shown, the surface area of ​​the Mylar film is larger than the opening area on the upper side of the covering box, so it can completely cover the upper side opening of the covering box, and the edge of the Mylar film extends out from the edge of the covering box and hangs in the air. The Mylar film feeding mechanism 76 and the Mylar film pasting mechanism 77 are both existing mature equipment and will not be described in detail here. The edging mechanism 78 is arranged at the edging station, and the edging mechanism 78 can wrap the Mylar film on the semi-finished product and fix it on the semi-finished product. The semi-finished product that has been edged by the edging mechanism 78 flows to the unloading station 710, and the sixth operating mechanism removes the edged semi-finished product from the edging carrier 72 at the unloading station 710 and transports it to the downstream station. The specific sixth transfer mechanism 860 can be any existing manipulator and is not specifically limited here.

[0127] like Figure 24 and Figure 25 As shown, the hemming mechanism 78 includes a support frame 783, a downward pressure assembly 781, and a side pressure assembly 782. The support frame 783 is mounted on the fourth platform 980. The downward pressure assembly 781 includes a downward pressure drive 7811 and a downward pressure head 7812. The downward pressure drive 7811 is mounted on the support frame 783. The downward pressure head 7812 is connected to the output end of the downward pressure drive 7811. The downward pressure drive 7811 can drive the downward pressure head 7812 to move in the up and down directions to press the Mylar film onto the upper surface of the semi-finished product. The side pressure assembly 782 includes a plurality of lifting drives 7823, a plurality of side pressure drives 7821, and a plurality of side pressure heads 7822. The lifting drives 7823 are connected to the output end of the downward pressure drive 7811. The side pressure drive 7821 is connected to the output end of the lifting drive 7823. The side pressure head 7822 is connected to the output end of the side pressure drive 7821. When the downward pressure driving member 7811 drives the downward pressure head 7812 to move downward, the entire side pressure assembly 782 moves downward synchronously. After the downward pressure head 7812 is attached to the Mylar film on the upper surface of the battery cell, the lifting driving member 7823 continues to output the upward and downward movement, so that the side pressure head 7822 connected to the lifting driving member 7823 pushes the edge of the Mylar film downward, causing the suspended portion to bend toward the side of the coating box. Then, the side pressure driving member 7821 drives the side pressure head 7822 to approach the side surface of the semi-finished product in the horizontal direction to press the edge of the Mylar film (i.e., the suspended portion) onto the side surface of the semi-finished product. Through the cooperation of the downward pressure assembly 781 and the side pressure assembly 782, the Mylar film is attached to the upper and side surfaces of the semi-finished product, that is, the coating of the semi-finished product is achieved.

[0128] In this embodiment, the downward pressure drive 7811, the lifting drive 7823 and the side pressure drive 7821 can all be cylinders or linear modules. Optionally, the downward pressure assembly 781 includes a downward pressure drive 7811 and two downward pressure heads 7812. One downward pressure drive 7811 can simultaneously drive the two downward pressure heads 7812 to move downward, and the two downward pressure heads 7812 respectively press two semi-finished products on a edging carrier 72. The side pressure assembly 782 includes seven lifting drives 7823, one of which is arranged between the two semi-finished products, and the remaining six lifting drives 7823 are respectively arranged on the remaining six sides of the two semi-finished products, and each lifting drive 7823 is connected to a side pressure drive 7821. The side pressure driving member 7821 connected to the lifting driving member 7823 arranged between the two semi-finished products is a two-way output cylinder, and the two output ends of the two-way output cylinder are respectively connected to a side pressure head 7822, so the two opposite sides of the two semi-finished products can be pressed together through a side pressure driving member 7821.
