[0023] The first clamping drive assembly is connected to the cell clamp to control the opening and closing of the cell clamp.

[0024] Furthermore, the feeding device includes a cell grouping transfer mechanism and a cell grouping rotation mechanism;

[0025] The cell grouping and transfer mechanism is located downstream of the cell stacking device along the cell moving sequence, and the cell grouping and transfer mechanism is provided with the module gripper;

[0034] Based on the above technical solutions, the technical effects achievable by this utility model can be analyzed as follows:

[0035] The battery cell stacking equipment provided by this utility model has a first direction, a second direction, and a third direction that intersect each other, and includes a feeding device, a battery cell stacking device, and a unloading device. The battery cell stacking device includes a support plate, a reference plate, a first vertical pressing mechanism, a second vertical pressing mechanism, a first horizontal pressing mechanism, a second horizontal pressing mechanism, and a push plate pressing mechanism. The support plate is arranged along the first and second directions, and the reference plate is connected to the upper surface of the support plate at an angle. The push plate pressing mechanism is spaced apart from the support plate along the first direction and is located on the side of the support plate away from the reference plate, and can move towards or away from the reference plate. The device comprises: a first vertical clamping mechanism and a second vertical clamping mechanism located on opposite sides of the support plate along a third direction; a first horizontal clamping mechanism and a second horizontal clamping mechanism located on opposite sides of the support plate along a first direction, both of which can move towards or away from the support plate; a feeding device including a cell gripper located upstream of the support plate in the cell moving sequence, used to transfer the cell to the upper surface of the support plate; and a discharging device including a module gripper located downstream of the support plate in the cell moving sequence, used to transfer the cell module placed on the support plate.

[0036] The cell grippers of the feeding device sequentially transfer multiple cells to a support plate, with the terminal surfaces of the cells facing the reference plate. After each cell is transferred to the support plate, a second vertical clamping mechanism presses it down. Once all cells are on the support plate, a first vertical clamping mechanism lifts the support plate, achieving third-dimensional fixation of the cells. The second vertical clamping mechanism then lifts, and a first horizontal clamping mechanism moves closer to the support plate to abut against the sidewall of the cell, positioning the cell closest to it. The first horizontal clamping mechanism moves away from the support plate. A pusher clamping mechanism moves closer to the support plate, pushing the cells closer to the reference plate, ensuring the terminal surfaces of the cells are flush with the reference plate. The second horizontal clamping mechanism moves closer to the support plate, stacking the cells and improving stacking accuracy and production efficiency. The module grippers of the unloading device transfer the stacked cells to the next device from the support plate to the next cell module.

[0037] The feeding device enables the feeding of multiple battery cells one by one.

[0038] The support plate of the battery cell stacking device supports and fixes the battery cells; the push plate and the reference plate work together to position the battery cells; the first vertical pressing mechanism and the second vertical pressing mechanism fix the battery cells in the third direction; the first horizontal pressing mechanism and the second horizontal pressing mechanism drive multiple battery cells to move and stack to form a battery cell module.

[0039] The feeding device is used to feed multiple battery cells into a battery cell module.

[0040] This battery cell stacking equipment achieves automatic stacking of battery cells through a feeding device, a battery cell stacking device, and a unloading device, which improves the stacking accuracy and production efficiency. Furthermore, because the battery cell stacking device has a push plate pressing mechanism and a reference plate, it achieves side-push stacking based on the terminal surface of the battery cell during stacking, ensuring that the terminal surfaces of multiple battery cells are flush, thus improving the efficiency of subsequent processes such as welding.

They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0057] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0058] In automated processes for multi-cell batteries, most cell modules require the installation of module end plates and steel strips for binding. However, for modules that do not require the installation of end plates and steel strips, or for specific product process requirements of customers, it is necessary to design a suitable cell stacking mechanism.

[0059] In view of this, see Figure 1 The battery cell stacking device provided in this embodiment of the present invention has a first direction X, a second direction Y, and a third direction Z that intersect each other in pairs. It includes a feeding device, a battery cell stacking device 100, and a unloading device. The battery cell stacking device 100 includes a support plate 110, a reference plate 120, a first vertical pressing mechanism 130, a second vertical pressing mechanism 140, a first horizontal pressing mechanism 150, a second horizontal pressing mechanism 160, and a push plate pressing mechanism. The support plate 110 is arranged along the first direction X and the second direction Y. The reference plate 120 is connected to the upper surface of the support plate 110 at an angle. The push plate pressing mechanism is spaced apart from the support plate 110 along the first direction X and is located on the side of the support plate 110 away from the reference plate 120, and can move towards or away from the reference plate 120. The first vertical pressing mechanism... Mechanism 130 and the second vertical pressing mechanism 140 are located on both sides of the support plate 110 along the third direction Z; the first horizontal pressing mechanism 150 and the second horizontal pressing mechanism 160 are located on both sides of the support plate 110 along the first direction X, and both the first horizontal pressing mechanism 150 and the second horizontal pressing mechanism 160 can move towards or away from the support plate 110; the feeding device includes a cell gripper 310, which is located upstream of the support plate 110 in the cell 610 moving sequence, and is used to transfer the cell 610 to the upper surface of the support plate 110; the unloading device includes a module gripper 410, which is located downstream of the support plate 110 in the cell 610 moving sequence, and is used to transfer the cell module 620 placed on the support plate 110.

[0060] Specifically, in this paper, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, and the third direction Z is the same as the vertical direction. The first direction X and the second direction Y are two perpendicular directions in the horizontal plane. The support plate 110 and the reference plate 120 are vertically connected, and the outer wall of the reference plate 120 is flush with the side wall of the support plate 110, thereby expanding the usable area of ​​the support plate 110. The cell movement sequence refers to the order in which the cells pass through the processes during the stacking and assembly of the cells. This cell movement sequence defines the order in which the cells pass through each process, but does not limit the specific location of each process. That is, the cells pass through the feeding device, the cell stacking device, and the unloading device in sequence. The devices corresponding to each process in the cell stacking equipment can be arranged in a straight-line assembly line, or in an S-shape, L-shape, or Z-shape, etc. In this embodiment, the devices corresponding to the processes in the cell stacking equipment are arranged in an L-shape.

[0061] The cell gripper 310 of the feeding device sequentially transfers multiple cells 610 onto the support plate 110, with the terminal surfaces 611 of the multiple cells 610 facing the reference plate 120. After each cell 610 is transferred onto the support plate 110, the pressure block 141 of the second vertical pressing mechanism 140 presses down on the cell 610. When all the cells 610 have been transferred onto the support plate 110, the first vertical pressing mechanism 130 lifts the support plate 110, achieving third-direction Z-fixation of the multiple cells 610. The pressure block 141 of the second vertical pressing mechanism 140 is lifted, and the first horizontal pressing mechanism 150 moves towards the support plate 110. The directional movement abuts against the side wall of the battery cell 610 to position the battery cell 610 near the first horizontal pressing mechanism 150; the first horizontal pressing mechanism 150 moves away from the support plate 110; the push plate 170 moves towards the support plate 110, pushing multiple battery cells 610 towards the reference plate 120, so that the terminal surfaces 611 of the multiple battery cells 610 are in contact with the reference plate 120, achieving flush alignment of the terminal surfaces 611 of the multiple battery cells 610; the second horizontal pressing mechanism 160 moves towards the support plate 110, stacking the multiple battery cells 610, improving stacking accuracy and production efficiency. The module gripper 410 of the unloading device transfers the battery cell module 620 formed by stacking multiple battery cells 610 from the support plate 110 to the next device.

[0062] The feeding device feeds multiple battery cells 610 one by one. The support plate 110 of the battery cell stacking device 100 supports and fixes the battery cells 610; the push plate 170 and the reference plate 120 cooperate to position the battery cells 610; the first vertical pressing mechanism 130 and the second vertical pressing mechanism 140 fix the battery cells 610 in a fixed direction; the first horizontal pressing mechanism 150 and the second horizontal pressing mechanism 160 drive the multiple battery cells 610 to move and stack to form a battery cell module 620; wherein, the pressing block 141 of the second vertical pressing mechanism 140 is rotatable to avoid the battery cell gripper 310 of the feeding device. The unloading device unloads the battery cell module 620 formed by stacking multiple battery cells 610.

[0063] This cell stacking equipment achieves automatic stacking of cells 610 through a feeding device, a cell stacking device 100, and a unloading device, improving stacking accuracy and production efficiency. Furthermore, because the cell stacking device 100 has a pusher plate 170 and a reference plate 120, the cells 610 are stacked by pushing them sideways with the terminal surface 611 of the cells 610 as the reference, ensuring that the terminal surfaces 611 of multiple cells 610 are flush, thus improving the efficiency of subsequent processes such as welding.

[0064] The structure and shape of the cell stacking device 100 are described in detail below:

[0065] In an optional technical solution of this utility model embodiment, the first vertical pressing mechanism 130 is connected to the bottom wall of the support plate 110 to drive the support plate 110 to rise and fall. The second vertical pressing mechanism 140 is installed on the reference plate 120 and the pressing block 141 at the driving end is located above the support plate 110. The pressing block 141 is rotatable and can move towards or away from the support plate 110. The push plate pressing mechanism includes a side push driving member 171 and a push plate 170. The push plate 170 is located on the side of the support plate 110 away from the reference plate 120. The side push driving member 171 is connected to the push plate 170 to drive the push plate 170 to move towards or away from the support plate 110.

[0066] Specifically, in this embodiment, the side push drive 171 is configured as a side push cylinder, and the movable end of the side push cylinder is connected to the push plate 170.

[0067] The side-push drive 171 provides power to the push plate 170.

[0068] See Figure 2In an optional technical solution of this utility model embodiment, the cell stacking device 100 further includes a fixed plate 190 and a stacking conveyor line 180 extending along the first direction X. The stacking conveyor line 180 has a stacking position and a pushing position, which are spaced apart along the first direction X. The support plate 110 and the fixed plate 190 are spaced apart along the third direction Z. The first vertical pressing mechanism 130, the first horizontal pressing mechanism 150, and the second horizontal pressing mechanism 160 are all mounted on the fixed plate 190. The fixed plate 190 is connected to the stacking conveyor line 180 and can move along the first direction X to switch between the stacking position and the pushing position. The push plate 170 is opposite to the pushing position.

[0069] Specifically, a servo motor is installed at one end of the stacking conveyor line 180. The servo motor drives the stacking conveyor line 180 to move along the first direction X, thereby causing the fixed plate 190 to move along the first direction X. The first vertical pressing mechanism 130 includes multiple lifting cylinders, the extension and retraction ends of which are connected to the bottom wall of the support plate 110, driving the support plate 110 to rise and fall. The first horizontal pressing mechanism 150 and the second horizontal pressing mechanism 160 both include pressing cylinders. The fixed end of the pressing cylinder is installed on the fixed plate 190, and the movable end of the pressing cylinder is opposite to the battery cell 610 to push the battery cell 610 laterally. The second vertical pressing mechanism 140 includes a pressing cylinder and a pressing block 141. The fixed end of the pressing cylinder is installed on the reference plate 120, and the pressing block 141 is installed on the movable end of the pressing cylinder. The stacking conveyor line 180 is provided with a stacking position and a pushing position. When the fixed plate 190 is in the stacking position, the feeding device transfers the battery cell 610 to the support plate 110 and pushes multiple battery cells 610 to stack them. When the fixed plate 190 is in the pushing position, the push plate 170 pushes multiple battery cells 610 so that the electrode surface 611 of multiple battery cells 610 are all in contact with the reference plate 120.

[0070] The stacking conveyor line 180 realizes the transfer of the fixed plate 190; the fixed plate 190 realizes the supporting and fixing function of the first vertical pressing mechanism 130, the first horizontal pressing mechanism 150 and the second horizontal pressing mechanism 160.

[0071] In the optional technical solution of this utility model embodiment, multiple second vertical pressing mechanisms 140 and push plates 170 are provided, and multiple second vertical pressing mechanisms 140 are arranged at intervals along the first direction X; when the fixed plate 190 is in the pushing position, one push plate 170 corresponds to one second vertical pressing mechanism 140.

[0072] Specifically, in this embodiment, four second vertical pressing mechanisms 140 and four push plates 170 are provided; of course, a scheme in which one push plate 170 is provided and the width of one push plate 170 is greater than the width of the battery cell module 620 should also be within the protection scope of this utility model embodiment.

[0073] Multiple second vertical pressing mechanisms 140 are provided to press multiple battery cells 610 one by one, avoiding the problem that multiple battery cells 610 cannot be pressed together when their heights are inconsistent along the third direction Z; multiple push plates 170 are provided to push multiple battery cells 610.

[0074] The structure and shape of the feeding device are described in detail below:

[0075] In an optional embodiment of this utility model, the feeding device includes a first cell transfer mechanism 210, a second cell transfer mechanism 220, and a cell rotation mechanism 300; the first cell transfer mechanism 210, the second cell transfer mechanism 220, and the cell stacking device 100 are arranged in parallel intervals along the second direction Y, and the cell rotation mechanism 300 is located at the end of the first cell transfer mechanism 210 and the second cell transfer mechanism 220; the cell rotation mechanism 300 has a cell gripper 310, which grips the cell 610 of the first cell transfer mechanism 210 or the second cell transfer mechanism 220, rotates it, and transfers it to the support plate 110.

[0076] Specifically, the battery cell 610 has three types: one with adhesive on the front, one with adhesive on the back, and one without adhesive. When four battery cells 610 form a battery cell module 620, the positive and negative terminals of two adjacent battery cells 610 must be opposite, and there must be adhesive between two adjacent battery cells 610. Taking the left side adhesive of the battery cell module 620 as an example: the first is a battery cell 610 with adhesive on the front, the second is a battery cell 610 with adhesive on the back, the third is a battery cell 610 with adhesive on the front, and the last is a battery cell 610 without adhesive. The first battery cell transfer mechanism 210 and the second battery cell transfer mechanism 220 are used to transport different types of battery cells 610 to place the battery cells 610 on the support plate 110 according to the rules.

[0077] The first cell transfer mechanism 210 and the second cell transfer mechanism 220 are used to transport the cell 610; the cell rotation mechanism 300 is used to rotate and transfer the cell 610 to the support plate 110 to realize the feeding of the cell 610.

[0078] See Figure 3In an optional embodiment of this utility model, the cell rotation mechanism 300 includes a first moving drive component 320, a first lifting drive component 330, a first clamping drive component 340, and a first rotating drive component 350; the first moving drive component 320 extends along the second direction Y, the first lifting drive component 330 is mounted on the movable end of the first moving drive component 320 and extends along the third direction Z; the first rotating drive component 350 is mounted on the movable end of the first lifting drive component 330, the first rotating drive component 350 is connected to the first clamping drive component 340 to drive the first clamping drive component 340 to rotate; the first clamping drive component 340 is connected to the cell gripper 310 to control the opening and closing of the cell gripper 310.

[0079] Specifically, the first moving drive assembly 320 includes a lead screw module extending along the second direction Y. The movable end of the first moving drive assembly 320 can move along the second direction Y, driving the cell gripper 310 to move along the second direction Y. The first lifting drive assembly 330 includes a lead screw module extending along the third direction Z. The movable end of the second moving drive assembly 320 can move along the third direction Z, driving the cell gripper 310 to lift. The first rotating drive assembly 350 includes a servo motor. The movable end of the first rotating drive assembly 350 drives the cell gripper 310 to rotate. In this embodiment, the first rotating drive assembly 350 drives the cell gripper 310 to rotate horizontally by 90°. The first clamping drive assembly 340 includes a clamping cylinder. The first clamping drive assembly 340 controls the opening or closing of the cell gripper 310 to clamp or release the cell 610.

[0080] The first moving drive component 320 of the cell rotation mechanism 300 enables the cell gripper 310 to move along the second direction Y, thereby enabling the cell gripper 310 to be opposite to the first cell transfer mechanism 210, the second cell transfer mechanism 220 or the support plate 110; the first lifting drive component 330 enables the cell gripper 310 to be lifted and lowered along the third direction Z; the first clamping drive component 340 enables the cell gripper 310 to rotate horizontally; and the first rotation drive component 350 enables the cell gripper 310 to open or close.

[0081] The structure and shape of the feeding device are described in detail below:

[0082] In an optional embodiment of this utility model, the unloading device includes a cell grouping transfer mechanism 400 and a cell grouping rotation mechanism 500; the cell grouping transfer mechanism 400 is located downstream of the cell stacking device 100 along the cell 610 moving sequence, and is provided with a module gripper 410; the cell grouping rotation mechanism 500 is located downstream of the cell grouping transfer mechanism 400 along the cell 610 moving sequence; the module gripper 410 grips the cell module 620 on the support plate 110 and transfers it to the cell grouping rotation mechanism 500, which is used to flip the cell module 620.

[0083] Specifically, along the movement sequence of the battery cells 610, the battery cell grouping and transfer mechanism 400 is located downstream of the battery cell stacking device 100.
