[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding this invention, and not for limiting it. Furthermore, in the drawings, structures that are similar or identical are indicated by the same reference numerals.

[0031] To facilitate understanding of the present invention, the battery cell end-plate stacking device provided in the embodiments of the present invention will be described first. Referring to Figures 1 to 3, the battery cell end-plate stacking device is used for stacking and assembling battery cells 90 and end plates 80. The battery cell end-plate stacking device includes: a frame 10, on which at least one carrier 5 is provided; a first robot 20, used to place the end plate 80 into the carrier 5; a pushing mechanism 40, disposed on the frame 10 and adjacent to the carrier 5, used to push the end plate 80 in the carrier 5 so that it mates with the internal contour of the carrier 5 to fix the position of the end plate 80; and a second robot 30, used to stack the battery cell 90 on the end plate 80 so that the battery cell 90 and the end plate 80 are connected as one unit.

[0032] In practical implementation, the cell endplate stacking device is mainly used in the mass production of lithium batteries. A lithium battery includes components such as a cell 90 and an endplate 80. During lithium battery production, the cell 90 and endplate 80 need to be stacked and assembled together to form a single unit. The cell 90 and endplate 80 are bonded together using double-sided adhesive or back adhesive. This embodiment uses a cell endplate stacking device to automate the assembly of the cell 90 and endplate 80. The entire device includes a frame 10, a first robot 20, a propulsion mechanism 40, and a second robot 30. The frame 10 serves as the framework for mounting various mechanisms and components. The upper side of the frame 10 is a platform structure, on which at least one carrier 5 is mounted. The carrier 5 is a tooling mold that can accommodate the endplate 80. One carrier 5 can accommodate one endplate 80, used for assembling one endplate 80 with one cell 90. Both the first robot 20 and the second robot 30 are industrial robots, positioned near the frame 10. In this embodiment, the first robot 20 and the second robot 30 are four-axis structures; in other embodiments, a six-axis structure or other axis structures may be used. The first robot 20 and the second robot 30 are programmed to perform precise pick-and-place operations on the battery cell 90 and the end plate 80 according to a set program. Specifically, the first robot 20 is responsible for picking up and placing the end plate 80, and the second robot 30 is responsible for picking up and placing the battery cell 90. In practical applications, the first robot 20 is used to place the end plate 80 into the carrier 5. A propulsion mechanism 40, located on the frame 10 adjacent to the carrier 5, pushes the end plate 80 within the carrier 5 to mate with the internal contour of the carrier 5, thus fixing the position of the end plate 80. Specifically, the propulsion mechanism 40 pushes the end plate 80 to mate with the internal contour of the carrier 5. Once the end plate 80, pushed by the propulsion mechanism 40, reaches the pre-marked position within the carrier 5, it cannot move further, maintaining its fixed position and thus meeting the high-precision requirements of pre-assembly. After the end plate 80 is positioned within the carrier 5, the second robot 30 stacks the battery cells 90 onto the end plate 80. Double-sided adhesive or backing adhesive is pre-applied to the upper side of the end plate 80 or the lower side of the battery cells 90. Once stacked on the end plate 80, the battery cells 90 adhere firmly to each other, thus connecting the battery cells 90 and the end plate 80 as a single unit, completing the stacking assembly. The assembled product can then continue to flow into the next production line. Throughout the entire stacking assembly process, the first robot 20, the second robot 30, and the propulsion mechanism 40 are controlled by a PLC or other control system to coordinate in an orderly manner. The process is as follows: the first robot 20 picks up the end plate 80—the second robot 30 picks up the battery cells 90—the first robot 20 places the end plate 80—the propulsion mechanism 40 positions the end plate 80—the second robot 30 discharges the battery cells 90. This achieves automated and precise stacking assembly of the battery cells 90 and the end plate 80, greatly improving product production efficiency.

[0033] The battery cell end plate stacking device in this embodiment has a carrier and a propulsion mechanism set on the frame. The first robot puts the end plate into the carrier, and the propulsion mechanism pushes the end plate in the carrier to match the internal contour of the carrier to fix the position of the end plate and meet the assembly accuracy requirements of the product. Then, the second robot stacks the battery cell on the end plate, so that the battery cell and the end plate are connected as one unit, thereby realizing the precise stacking and assembly of battery cell and end plate, improving the production efficiency of the product while ensuring the quality of the product.

[0034] In one embodiment, referring to FIG2, the frame 10 is provided with a first moving mechanism 11 and a second moving mechanism 12. Each of the first moving mechanism 11 and the second moving mechanism 12 is provided with at least one of the aforementioned carriers 5. Both the first moving mechanism 11 and the second moving mechanism 12 are used to drive the carriers 5 to move horizontally reciprocally, and the directions in which the first moving mechanism 11 and the second moving mechanism 12 drive the carriers 5 to move in opposite directions. In specific implementations, for batch assembly and stacking, multiple carriers 5 are provided. The first moving mechanism 11 and the second moving mechanism 12 are provided on the frame 10 to drive the carriers 5 to move horizontally reciprocally. Each of the first moving mechanism 11 and the second moving mechanism 12 is provided with at least one carrier 5, and the directions in which the first moving mechanism 11 and the second moving mechanism 12 drive the carriers 5 to move in opposite directions, thus achieving a one-for-one backup. Specifically, in practical applications, assuming A and B are two opposite directions, the rack 10 has a material preparation area in the A direction and an assembly area in the B direction. The first moving mechanism 11 drives the carrier 5 to move along the A direction to the material preparation area on the rack 10 and stop there. At this time, the second moving mechanism 12 drives the carrier 5 to move along the B direction to the assembly area on the rack 10 and stop there. In the assembly area, the first robot 20 puts the end plate 80 into the carrier 5 on the first moving mechanism 11 for material preparation. In the assembly area, the pushing mechanism 40 and the second robot 30 cooperate to stack and assemble the end plate 80 and the battery cell 90 in the carrier 5 on the second moving mechanism 12. After assembly, the battery cell 90 is removed by manual labor or robot and flows into the next production line. After the end plate 80 is removed from the carrier 5 on the second moving mechanism 12, the carrier 5 on the first moving mechanism 11 has completed material preparation in the material preparation area. The first moving mechanism 11 moves the carrier 5 along direction B to the assembly area, and the second moving mechanism 12 moves the carrier 5 along direction A to the material preparation area. In the material preparation area, the first robot 20 places the end plate 80 into the carrier 5 on the second moving mechanism 12 for further material preparation. In the assembly area, the propulsion mechanism 40 and the second robot 30 cooperate again to stack and assemble the end plate 80 and the battery cell 90 in the carrier 5 on the first moving mechanism 11. Overall, through the cooperation of the first moving mechanism 11 and the second moving mechanism 12, material preparation and stacking assembly are carried out simultaneously, greatly improving the stacking assembly efficiency of the battery cell 90 and the end plate 80.

[0035] Further referring to Figures 2 and 3, both the first moving mechanism 11 and the second moving mechanism 12 include a slide rail 2, a mounting plate 3, and a drive assembly 4. The slide rails 2 of the first moving mechanism 11 and the second moving mechanism 12 are arranged parallel to each other on the frame 10. The mounting plate 3 is slidably mounted on the slide rail 2. The carrier 5 is mounted on the mounting plate 3. The drive assembly 4 is mounted on the frame 10 and is drively connected to the mounting plate 3. The drive assembly 4 is used to drive the mounting plate 3 to slide back and forth along the slide rail 2 so that the carrier 5 moves horizontally back and forth. In specific implementation, the first moving mechanism 11 and the second moving mechanism 12 adopt the same structure, both including a slide rail 2, a mounting plate 3, and a drive assembly 4. The slide rails 2 of the first moving mechanism 11 and the second moving mechanism 12 are arranged parallel to each other on the frame 10. The mounting plate 3 is slidably mounted on the slide rail 2. Specifically, the bottom of the mounting plate 3 is provided with a slider or pulley to slide in cooperation with the slide rail 2, while the carrier 5 is fixedly mounted on the upper side of the mounting plate 3. The drive assembly 4 is mounted on the frame 10 and is connected to the mounting plate 3 via a transmission. The drive assembly 4 can be a motor drive structure or a cylinder drive structure. The drive assembly 4 drives the mounting plate 3 to move back and forth along the slide rail 2, causing the carrier 5 to move back and forth, thereby realizing the simultaneous preparation of materials and stacking assembly, and improving the production efficiency of the product.

[0036] Furthermore, referring to Figures 3 and 4, the carrier 5 includes a base 51 and a plurality of positioning blocks 52. The base 51 is disposed on the upper side of the mounting plate 3, and the plurality of positioning blocks 52 are respectively disposed around the base 51 and extend above the upper side of the base 51. The first robot 20 places the end plate 80 into the inner perimeter of the plurality of positioning blocks 52 on the base 51, and the propulsion mechanism 40 pushes the end plate 80 to abut against the positioning blocks 52 to fix the position of the end plate 80. In specific implementation, the carrier 5 mainly consists of a base 51 and a plurality of positioning blocks 52. The base 51 is fixedly disposed on the upper side of the mounting plate 3, and the upper side of the base 51 is a planar structure that can support the end plate 80. Multiple positioning blocks 52 are respectively arranged around the base 51, and all positioning blocks 52 are higher than the base 51 by a certain height. The positioning blocks 52 are block-shaped structures, and all positioning blocks 52 enclose a space on the upper side of the base 51 that can accommodate the entire end plate 80. Their shapes are adapted to the shape of the end plate 80, and the inner contour shape of all positioning blocks 52 is adapted to the side shape of the end plate 80. In practical applications, the first robot 20 places the end plate 80 into the inner perimeter of the multiple positioning blocks 52 on the base 51, so that the end plate 80 is in the space enclosed by the multiple positioning blocks 52 on the upper side of the base 51. The pushing mechanism 40 pushes the end plate 80 to abut against the positioning blocks 52. The side of the end plate 80 matches the inner perimeter of the positioning blocks 52, thereby restricting the movement of the end plate 80 and accurately fixing the position of the end plate 80 in the carrier 5. The positioning accuracy of the end plate 80 is improved, and the second robot 30 can accurately stack the battery cell 90 on the end plate 80 to complete the assembly.

[0037] Furthermore, referring to Figures 4 and 5, the positioning block 52 includes a first step portion 521 and a second step portion 522. The first step portion 521 is located around the perimeter of the base 51, and the second step portion 522 is located outside the first step portion 521 and extends above it. The first robot 20 places the end plate 80 inside the first step portion 521 on the base 51, and the propulsion mechanism 40 pushes the end plate 80 to abut against the inner side of the first step portion 521 to fix the position of the end plate 80. In specific implementation, the positioning block 52 mainly consists of a first step portion 521 and a second step portion 522. The first step portion 521 is fixed at the perimeter of the base 51, and the second step portion 522 is located outside the first step portion 521 and extends above it by a certain height, forming a stepped structure with one high and one low, with the first step portion 521 at the bottom and the second step portion 522 at the top. In practical applications, the first robot 20 places the end plate 80 onto the base 51. The end plate 80 will be located inside the first step 521. After the pushing mechanism 40 pushes the end plate 80, the end plate 80 abuts against the inner side of the first step 521. The side of the end plate 80 is attached to the step surface in the horizontal direction of the first step 521. The end plate 80 is restricted by the first step 521 and will not move. Thus, the position of the end plate 80 is accurately fixed. The second robot 30 can accurately stack the battery cell 90 on the end plate 80 to complete the assembly.

[0038] In one embodiment, referring to FIG3, the propulsion mechanism 40 includes a telescopic drive member 41 and a propulsion member 42. The telescopic drive member 41 is disposed on the mounting plate 3 and located on one side edge of the base 51. The propulsion member 42 is connected to the telescopic drive member 41 and its shape matches the side edge of the end plate 80. The telescopic drive member 41 is used to drive the propulsion member 42 to extend into the inner periphery of the positioning block 52 to push the end plate 80 to abut against the positioning block 52. In specific implementation, the propulsion mechanism 40 is mainly composed of the telescopic drive member 41 and the propulsion member 42. In this embodiment, the telescopic drive member 41 is a cylinder. In other embodiments, other electric devices capable of telescopic propulsion can be used. The telescopic drive member 41 is fixed on the mounting plate 3 and located on one side edge of the base 51. Specifically, on the periphery of the base 51, the side where the telescopic drive member 41 is disposed does not have a positioning block 52, leaving space for the propulsion of the telescopic drive member 41. The pusher 42 is a block structure, with one side of its shape matching the side shape of the end plate 80. The pusher 42 is connected to the telescopic shaft of the telescopic drive 41. In practical applications, the telescopic drive 41 drives the pusher 42 to push the end plate 80 diagonally. Specifically, the telescopic drive 41 drives the pusher 42 to extend towards the inner perimeter of the positioning block 52. The pusher 42, with its side matching the side of the end plate 80, pushes towards the end plate 80, thereby causing the end plate 80 to abut against the positioning block 52, completing precise positioning.

[0039] In one embodiment, referring to FIG1, the cell endplate stacking device further includes a first feeding mechanism 60 and a second feeding mechanism 70. The first feeding mechanism 60 and the second feeding mechanism 70 are respectively arranged adjacent to the first robot 20 and the second robot 30. The first feeding mechanism 60 and the second feeding mechanism 70 are respectively used to transport the endplate 80 and the cell 90 to a preset position for parking to provide to the first robot 20 and the second robot 30. In practice, after the battery cell 90 and the end plate 80 are stacked and assembled, they flow into the next production line, where a new round of stacking and assembly is required. End plates 80 and battery cells 90 need to be continuously and automatically supplied for backup. In this embodiment, the end plates 80 and battery cells 90 are supplied by the first feeding mechanism 60 and the second feeding mechanism 70. The first feeding mechanism 60 and the second feeding mechanism 70 are respectively arranged adjacent to the first robot 20 and the second robot 30. The first feeding mechanism 60 is responsible for supplying the end plate 80, while the second feeding mechanism 70 is responsible for supplying the battery cell 90. The first feeding mechanism 60 and the second feeding mechanism 70 can adopt a production line 7 mechanism. In practical applications, the materials for the battery cell 90 and end plate 80 can be supplied by the previous production line. The first feeding mechanism 60 and the second feeding mechanism 70 respectively transport the end plate 80 to the preset position for parking. When the battery cell 90 and end plate 80 are parked, the first robot 20 and the second robot 30 respectively pick up the parked end plate 80 and battery cell 90, and cooperate with the pushing mechanism 40 to complete the stacking assembly. After the previous end plate 80 and battery cell 90 are removed, the first feeding mechanism 60 and the second feeding mechanism 70 will replenish the new end plate 80 and battery cell 90 to achieve continuous material supply and improve the production efficiency of the product.

[0040] Further, referring to Figure 1, both the first feeding mechanism 60 and the second feeding mechanism 70 include a feeding platform 6 and a production line 7. The feeding platform 6 is arranged adjacent to the first robot 20 and the second robot 30, respectively. The production line 7 is arranged on the feeding platform 6. The production line 7 is used to transport the end plate 80 and the battery cell 90 to a fixed position on the feeding platform 6 for stopping. In specific implementation, both the first feeding mechanism 60 and the second feeding mechanism 70 are composed of a feeding platform 6 and a production line 7. The feeding platform 6 of the first feeding mechanism 60 is arranged adjacent to the first robot 20, and the feeding platform 6 of the second feeding mechanism 70 is arranged adjacent to the second robot 30. The production line 7 is set on the corresponding feeding platform 6. Specifically, part of the production line 7 is located on the production line 7, and the other part extends to the previous production line or the area where materials are manually fed. The production line 7 of the first feeding mechanism 60 is responsible for transporting the end plate 80, and the production line 7 of the second feeding mechanism 70 is responsible for transporting the battery cell 90. Specifically, the end plate 80 and the battery cell 90 are arranged in a line along the flow direction of the production line 7 on the corresponding production line 7. The production line 7 transports the end plate 80 and the battery cell 90 to a fixed position on the feeding platform 6 and stops them. The first robot 20 and the second robot 30 respectively grab the end plate 80 and the battery cell 90 on the corresponding production line 7 at the fixed position on the corresponding feeding platform 6. After the first robot 20 and the second robot 30 remove the end plate 80 and the battery cell 90, a gap appears in the original position. The production line 7 continues to fill the gap with the end plate 80 and the battery cell 90, providing material for the first robot 20 and the second robot 30 to carry out the next round of stacking assembly, thereby improving the production efficiency of the product.

[0041] In one embodiment, referring to Figures 6 and 7, both the first robot 20 and the second robot 30 are provided with a plurality of pickers 21 arranged at intervals along the same direction. The frame 10 is provided with a plurality of carriers 5. The first robot 20 uses the plurality of pickers 21 to pick up a plurality of end plates 80 and place them into a plurality of carriers 5. The second robot 30 uses the plurality of pickers 21 to pick up a plurality of battery cells 90 and stack them on a plurality of battery cells 90. In specific implementation, several carriers 5 are set on the frame 10. All carriers 5 are arranged at intervals along the same direction, which can simultaneously stack and assemble multiple end plates 80 and battery cells 90. The first robot 20 and the second robot 30 are equipped with multiple spaced pickers 21. The pickers 21 are specifically grippers or suction cups. The first robot 20 can pick up multiple end plates 80 at one time through multiple pickers 21 and put the multiple end plates 80 into the corresponding carriers 5 on the corresponding frame 10. The second robot 30 can pick up multiple battery cells 90 at one time through multiple pickers 21 and stack them on multiple end plates 80 that have been positioned by the push mechanism 40, so as to realize the batch stacking and assembly of battery cells 90 and end plates 80, thereby increasing production capacity and further improving the production efficiency of the product.

[0042] In one embodiment, the cell endplate stacking device further includes a third robot (not shown in the figure), which is disposed adjacent to the frame 10. The third robot is used to pick up the integrated cell 90 and endplate 80 and place them in a predetermined position. Specifically, the third robot is positioned adjacent to the frame 10 and is mainly responsible for removing the stacked and assembled integrated cell 90 and endplate 80 from the carrier 5 and placing them in a predetermined area or allowing them to flow into the next production line. In this embodiment, the third robot is a six-axis robot; in other embodiments, the third robot may use other axis structures, which are not limited here. In practical applications, by using the third robot to remove the stacked and assembled cell 90 and endplate 80, space is left in the carrier 5 for a new round of stacking and assembly, thereby achieving continuous product production.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
