DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0035] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0036] According to an embodiment of the present utility model, on the one hand, a battery cell stacking and extrusion device 100 is provided, such as Figures 1 to 4 As shown, it includes: a carrier 1, a cell shifting mechanism 2 and an extrusion mechanism 3. The carrier 1 has a carrier position 11, which is extended along a first direction to carry a plurality of cells arranged along the first direction. The cell shifting mechanism 2 can be reciprocated along the first direction, and the cell shifting mechanism 2 is suitable for moving the cells on the carrier position 11 so that adjacent cells are arranged in a close relationship. The extrusion mechanism 3 has two extrusion surfaces, which are arranged at opposite ends of the carrier position 11 along the first direction, and the two extrusion surfaces are suitable for approaching or moving away from each other.

[0037] The battery cell stacking and extrusion device 100 of the present embodiment is applied, and the battery cells located on the supporting position 11 are moved by the battery cell shifting mechanism 2 to fit adjacent battery cells together, thereby completing the stacking of the battery cells, and the battery cells stacked at the supporting position 11 are directly extruded by the extrusion mechanism 3. Therefore, the stacking and extrusion actions of the battery cells can be completed on the supporting position 11 of the supporting platform 1, that is, the stacking station and the extrusion station are integrated, and there is no need to transfer the battery cells between the two stations, which simplifies the overall structure of the processing equipment and reduces the occupation of the production space.

[0038] In the related art, in order to realize the stacking and extrusion of battery cells, a tower stacking table that can rotate 180° or 360° and an independently set extrusion table are usually provided. Specifically, a loading robot grabs the battery cells and places them on the stacking table for stacking. After the stacking is completed, the stacking table rotates 180° to face the unloading robot, and the unloading robot moves the stacked modules to the extrusion table for extrusion. In the above-mentioned related art solution, the stacking table has high cost and complex structure, and can only realize a single stacking action. In the technical solution of this embodiment, as Figure 1As shown, the battery cell stacking and extrusion device 100 is integrated with the battery cell shifting mechanism 2 and the extrusion mechanism 3, so that the battery cell stacking and extrusion device 100 of this embodiment can realize both stacking action and extrusion action, simplifying the required devices and action steps for realizing stacking and extrusion, and improving production efficiency.

[0039] In one embodiment, Figure 1 As shown, the battery cell shifting mechanism 2 is arranged on the supporting platform 1 .

[0040] In one embodiment, Figures 1 to 3 As shown, the carrying platform 1 includes a mounting platform 13 and a carrying plate 14 . Both the mounting platform 13 and the carrying plate 14 are extended along a first direction. The carrying plate 14 is arranged on the surface of the mounting platform 13 , and the carrying position 11 is arranged corresponding to the upper surface of the carrying plate 14 .

[0041] In one embodiment, Figures 1 to 3 As shown, the extrusion mechanism 3 includes a positioning structure 31 and an extrusion structure 32. The positioning structure 31 is fixedly arranged on the carrier 1. The extrusion structure 32 is arranged at a relative interval with the positioning structure 31. The two surfaces of the positioning structure 31 and the extrusion structure 32 that are arranged opposite to each other form two extrusion surfaces. The extrusion structure 32 is suitable for approaching or moving away from the positioning structure 31. When extrusion is required after stacking is completed, the extrusion structure 32 moves close to the positioning structure 31 to clamp and extrude a plurality of battery cells between the positioning structure 31 and the extrusion structure 32 to achieve an extrusion action; when a plurality of battery cells (i.e., modules) need to be removed from the carrier 1, the extrusion structure 32 moves away from the positioning structure 31 to loosen the modules.

[0042] Specifically, Figure 1 As shown, the positioning structure 31 is disposed on the mounting platform 13 and corresponds to one end of the supporting plate 14 along the first direction, and the pressing structure 32 is movably disposed relative to the mounting platform 13 and is disposed close to the other end of the supporting plate 14 along the first direction.

[0043] In one embodiment, Figure 1 and Figure 2 As shown, the battery cell shifting mechanism 2 includes a clamping assembly 21, which is suitable for clamping the battery cell and driving the battery cell to move along a first direction. When the battery cell needs to be moved, the clamping assembly 21 clamps the battery cell and drives the battery cell to move. After the battery cell is moved into place, the clamping assembly 21 releases the battery cell.

[0044] It is worth noting that, in other alternative embodiments, the battery cell shifting mechanism 2 includes a pushing structure, and the pushing structure is suitable for pushing the battery cells along the first direction to make adjacent battery cells fit together.

[0045] In one embodiment, Figure 1As shown, the cell stacking and extruding device 100 further includes a driving mechanism 4, which is in transmission connection with the extruding structure 32 and the clamping assembly 21 at the same time, and the clamping assembly 21 is arranged on the side of the extruding structure 32 close to the positioning structure 31. In this arrangement, the same driving mechanism 4 is used to drive the extruding structure 32 and the clamping assembly 21 at the same time, which simplifies the overall structure for driving the extruding structure 32 and the clamping assembly 21, and facilitates the arrangement of the driving mechanism 4.

[0046] In one embodiment, Figure 1 As shown, the driving mechanism 4 includes a motor 41 and a screw rod 42. The motor 41 is arranged on the supporting platform 1. The screw rod 42 is extended along the first direction. The extrusion structure 32 and the clamping assembly 21 are both threadedly connected to the screw rod 42. The motor 41 is suitable for driving the screw rod 42 to rotate, so that the extrusion structure 32 and the clamping assembly 21 move on the screw rod 42 at the same time.

[0047] In one embodiment, Figure 2 As shown, the extrusion structure 32 includes a first slide seat 321, a connecting structure 322 and an extrusion plate 323. The first slide seat 321 is threadedly connected to the screw rod 42. The lower end of the connecting structure 322 is connected to the first slide seat 321. The upper end of the connecting structure 322 is connected to one side of the extrusion plate 323. The other side of the extrusion plate 323 forms an extrusion surface.

[0048] Further, such as Figure 1 As shown, the mounting platform 13 includes a top plate 131, a bottom plate 132 and a connecting plate 133. The top plate 131 and the bottom plate 132 are arranged relative to each other in the vertical direction, and the connecting plate 133 is connected between the top plate 131 and the bottom plate 132, so that an installation space is formed in the mounting platform 13. The screw rod 42 and the first slide seat 321 are both located in the installation space. The top plate 131 is provided with a first slide groove 1311, and the first slide groove 1311 is extended along the first direction. The first slide groove 1311 is connected to the installation space, and the connecting structure 322 passes through the first slide groove 1311 and is movably arranged along the first slide groove 1311.

[0049] It should be noted that if Figure 4 As shown, the carrier plate 14 includes a first plate body 141 and a second plate body 142, both of which are extended along the first direction, and the first plate body 141 and the second plate body 142 are relatively spaced apart along the second direction, and the first slide groove 1311 extends to be opened between the first plate body 141 and the second plate body 142. In this way, when the extrusion structure 32 and the clamping assembly 21 move along the first direction, interference between the extrusion structure 32 and the carrier plate 14 is avoided.

[0050] In one embodiment, Figure 2As shown, the cell shifting mechanism 2 further includes a second slide 22, the second slide 22 is threadedly connected to the screw rod 42, and the clamping assembly 21 is disposed on the second slide 22. Figure 2 As shown, the clamping assembly 21 includes a clamping jaw 211 and a clamping jaw driving unit 212. A pair of clamping jaws 211 are arranged at a relative interval. The pair of clamping jaws 211 are arranged on opposite sides of the carrier plate 14 along the second direction. The clamping jaw driving unit 212 is suitable for driving the pair of clamping jaws 211 to move closer to or away from each other. Figure 2 and Figure 4 As shown, the top plate 131 is also provided with a second slide groove 1312, and the second slide groove 1312 is extended along the first direction. There are two second slide grooves 1312, and the two second slide grooves 1312 are arranged on opposite sides of the supporting plate 14 along the second direction. The second slide groove 1312 is connected to the installation space, and a pair of clamps 211 respectively penetrate the two second slide grooves 1312 and are movably arranged along the second slide grooves 1312.

[0051] It is worth mentioning that please refer to Figure 2 Two clamping assemblies 21 are arranged at intervals along the first direction, and the two clamping assemblies 21 are both arranged on the second slide seat 22 .

[0052] Please note that Figure 1 The clamping assembly 21 is located on the side of the extrusion structure 32 close to the positioning structure 31. Therefore, when the clamping assembly 21 clamps the battery cell and drives the battery cell to move along the first direction, it will not be disturbed by the extrusion structure 32; when the battery cell stacking is completed and needs to be extruded, the extrusion structure 32 and the clamping assembly 21 move toward the battery cell synchronously. At this time, each pair of jaws 211 are in a state of moving away from each other, so that the battery cell enters between each pair of jaws 211, and then the extrusion structure 32 is attached to the battery cell and applies extrusion force.

[0053] In one embodiment, Figure 1 As shown, a slide rail 7 is disposed on the upper surface of the bottom plate 132 . The slide rail 7 is extended along a first direction. The first slide seat 321 and the second slide seat 22 are both slidably connected to the slide rail 7 .

[0054] In one embodiment, Figure 2 As shown, an elastic buffer structure 5 is provided between the clamping assembly 21 and the extrusion structure 32. By providing the elastic buffer structure 5, a hard collision between the clamping assembly 21 and the extrusion structure 32 is avoided, thereby preventing the device from being damaged.

[0055] Specifically, the elastic buffer structure 5 can be a spring, an elastic pad or a cylinder.

[0056] Of course, in other alternative embodiments, the extrusion mechanism 3 further includes an extrusion drive structure, which is in transmission connection with the extrusion structure 32, and the battery cell shifting mechanism 2 further includes a clamping drive structure, which is in transmission connection with the clamping assembly 21. That is, separate drive structures are provided for the extrusion structure 32 and the clamping assembly 21, respectively. In this case, the extrusion drive structure can be provided as an electric cylinder with adjustable pressure, which is provided on the mounting platform 13, and the drive end of the electric cylinder is connected to the extrusion structure 32.

[0057] It should be noted that the above-mentioned alternative embodiment is relatively complex in structure compared to using the driving mechanism 4 to simultaneously drive the extrusion structure 32 and the clamping assembly 21. In addition, the driving stroke of the electric cylinder is limited, while the driving stroke of the motor 41 and the screw rod 42 is longer. Therefore, the extrusion structure 32 can be applied to modules of various lengths, has stronger compatibility, and can achieve rapid changeover.

[0058] In one embodiment, Figure 3 As shown, a pressure sensing unit 6 is provided on the positioning structure 31, and the pressure sensing unit 6 is provided corresponding to the extrusion surface. By providing the pressure sensing unit 6, the extrusion force applied to the battery cell by the extrusion mechanism 3 is detected and controlled, thereby improving the safety during the extrusion process.

[0059] Of course, in other alternative implementations, the pressure sensing unit 6 may also be disposed on the extrusion structure 32 , or the pressure sensing unit 6 may be disposed on both the positioning structure 31 and the extrusion structure 32 .

[0060] In one embodiment, Figure 1 and Figure 4 As shown, grooves 12 are provided on the carrier 1, and the grooves 12 are provided at both ends of the carrier position 11 along the first direction. The grooves 12 are provided for pre-placing the steel strip, so that the steel strip can be put on the battery cell when the extrusion mechanism 3 puts the battery cell in an extrusion state.

[0061] Specifically, Figure 1 and Figure 4 As shown, the groove 12 is arranged to penetrate the carrying plate 14 along the second direction.

[0062] It should be noted that the first direction and the second direction are perpendicular to each other.

[0063] According to an embodiment of the present invention, on the other hand, a module processing production line is also provided, such as Figures 5 to 7 As shown, it comprises: a cell feeding device 200 and the cell stacking and pressing device 100. The cell stacking and pressing device 100 is arranged downstream of the cell feeding device 200 and is suitable for receiving the cells fed by the cell feeding device 200.

[0064] The module processing production line of this embodiment applies the above-mentioned battery cell stacking and extrusion device 100. By integrating the stacking station and the extrusion station, there is no need to transfer the battery cells between the two stations. The overall structure of the battery cell stacking and extrusion device 100 is simple, thereby simplifying the structure of the module processing production line and reducing the space occupied by the production line.

[0065] It is worth noting that the battery cell loading device 200 can load one battery cell at a time, or can load several battery cells at a time, and the number of battery cells loaded at a time can be specifically set according to the actual production rhythm.

[0066] Specifically, Figure 5 and Figure 6 As shown, the battery cell loading device 200 includes a battery cell conveyor line 201 and a loading robot 202 . The battery cell conveyor line 201 is suitable for continuously conveying battery cells, and the loading robot 202 is suitable for loading the battery cells of the battery cell conveyor line 201 to the battery cell stacking and extrusion device 100 .

[0067] Furthermore, a cell processing station may be provided corresponding to the cell incoming material conveying line 201, including cell incoming material detection, laser cleaning, plasma cleaning, etc.

[0068] In one embodiment, Figure 7 As shown, the carrying position 11 is formed with a plurality of battery cell placement positions 111 spaced in sequence along the first direction, and the battery cell loading device 200 is suitable for loading a plurality of battery cells into the plurality of battery cell placement positions 111 in sequence.

[0069] The battery cells are loaded using the battery cell loading device 200 to arrange a plurality of battery cells in a plurality of battery cell placement positions 111, with adjacent battery cells spaced apart. The battery cells are moved by the battery cell shifting mechanism 2 to eliminate the space between adjacent battery cells so that adjacent battery cells are closely attached to each other, thereby completing the stacking of the battery cells. The battery cell shifting mechanism 2 has a short moving distance for the battery cells, thereby avoiding damage to the blue film on the outer surface of the battery cells and improving the stacking efficiency.

[0070] It is worth noting that in the related art, the cell loading device 200 places the cell at the same point on the carrier 1 during each loading process, and then the cell can be moved by the cell shifting mechanism 2 to make adjacent cells fit together to complete the stacking. Therefore, the cell moving path will be longer during the cell stacking process, which will increase the time consumption, and the cell will rub against the carrier 1 for a long time during the movement process, which may easily cause damage to the blue film on the cell outer layer.

[0071] In this embodiment, if Figure 7As shown, when the battery cell loading device 200 loads the battery cells, the battery cells are placed at different points each time, that is, the battery cells are placed at their corresponding battery cell placement positions 111 each time, and a plurality of battery cells are placed in sequence on a plurality of battery cell placement positions 111. When the battery cells are moved by the battery cell shifting mechanism 2, the moving distance of the battery cells is only the distance between two adjacent battery cell placement positions 111. Therefore, the moving distance of the battery cells is greatly shortened, the battery cells are prevented from being damaged, and the stacking time can be shortened, thereby improving the stacking efficiency.

[0072] It should be noted that the cell loading process of the cell loading device 200 and the cell shifting mechanism 2 can be performed synchronously, that is, when the cell loading device 200 completes the loading of the second cell and is ready to load the third cell, the cell shifting mechanism 2 can move the second cell to fit the second cell with the first cell. Therefore, the loading and stacking time can be greatly shortened, and the production efficiency can be improved.

[0073] Furthermore, in one embodiment, the cell stacking and extruding device 100 is reciprocatingly arranged along the first direction so that a plurality of cell placement positions 111 correspond to the cell loading device 200 in sequence. In this arrangement, after the cell loading device 200 places the cell in one cell placement position 111, the cell stacking and extruding device 100 moves a predetermined distance along the first direction so that the next cell placement position 111 corresponds to the cell loading device 200. Therefore, it is not necessary to move the cell loading device 200 along the first direction for loading, and the cell stacking and extruding device 100 is to move along the first direction toward the next station after stacking is completed. Therefore, the loading action of the cell can be further simplified and the production efficiency can be improved.

[0074] It is worth mentioning that please refer to Figure 6 and Figure 7 , the cell placement position 111 on the far right corresponds to the cell loading device 200, and the cell loading device 200 loads the cell to the cell placement position 111; then the cell stacking and extruding device 100 moves to the right by a predetermined distance, so that the second cell placement position 111 on the right corresponds to the cell loading device 200, and the cell loading device 200 loads the cell to the cell placement position 111; this continues until the cell loading device 200 loads the cell to the leftmost cell placement position 111, and the loading of the cell stacking and extruding device 100 is completed. Afterwards, the cell stacking and extruding device 100 can drive a plurality of cells to continue to move to the right, that is, to the next process.

[0075] In one embodiment, Figure 5 and Figure 6As shown, a plurality of cell stacking and extruding devices 100 are sequentially arranged along the second direction, and the cell loading device 200 is suitable for sequentially loading a plurality of cell stacking and extruding devices 100. When the cell loading device 200 completes loading for one cell stacking and extruding device 100, the cell stacking and extruding device 100 can move toward the subsequent process, and then the cell loading device 200 can continue to load for another cell stacking and extruding device 100, thereby achieving uninterrupted loading and stacking of cells and improving module processing efficiency.

[0076] Specifically, in this embodiment, Figure 5 and Figure 6 As shown, the module processing production line also includes a machine 600, on which two sets of rails 700 are arranged in parallel along the second direction, and each set of rails 700 is extended along the first direction. Two battery cell stacking and extrusion devices 100 are provided, and the two battery cell stacking and extrusion devices 100 are respectively arranged on the two sets of rails 700 and can be movably arranged along the rails 700.

[0077] In one embodiment, Figure 1 and Figure 2 As shown, the module processing production line also includes a module shaping device 300 , which is arranged downstream of the battery cell feeding device 200 , and the battery cell stacking and extruding device 100 is suitable for driving a plurality of battery cells to transfer toward the module shaping device 300 .

[0078] In one embodiment, Figure 5 and Figure 6 As shown, the module processing production line further includes a module unloading device 400, which is disposed downstream of the module shaping device 300, and the battery cell stacking and extruding device 100 is suitable for driving a plurality of battery cells to transfer toward the module unloading device 400.
