Description

Technical Field

[0001] This invention belongs to the field of battery cell production technology, and relates to a battery cell formation system and its auxiliary devices. Background Technology

[0002] Battery activation, also known as formation, refers to the process of activating the positive and negative electrode materials through charging and discharging after battery manufacturing. It belongs to the field of energy technology and is mainly used in lithium batteries. This process involves forming a solid electrolyte interphase (SEI) film on the surface of the negative electrode during the initial charge. The SEI film's components include Li₂O and LiF, and its thickness is approximately 100-120 nanometers. Activation methods include directly charging the cell using a constant current and constant voltage source. Formation process parameters include temperature range (room temperature to 90°C), current magnitude, and cutoff voltage (3.5V~3.8V). Low-current formation helps form a dense organic film structure.

[0003] In the current formation process, it is usually necessary to use conductive clips to clamp the two tabs of the battery cell, then charge the battery cell, and heat and pressurize the battery cell. The purpose of heating and pressurizing is to drive the gas inside the battery cell into the air bag. Subsequently, the air bag is cut and separated by heat sealing, so that the gas inside the battery cell can be discharged to the outside.

[0004] To improve formation efficiency, multiple clips are typically installed on a formation plate. Each clip has a copper sheet (or other conductive material) on the part that holds the tab, which is connected to pre-embedded wires inside the formation plate. When the clip holds the tab, the formation plate connects to an external plug or connector, allowing all clips and tabs to be energized and charged. The formation plate also has raised heating plates on which the battery cells are laid, thus heating the tabs. During formation, multiple layers of formation plates are stacked. The presence of the heating plates ensures that different layers of formation plates can clamp the battery cells together, preventing the layers from affecting the clips and ensuring that the tabs can be properly energized. Summary of the Invention

[0038] The present invention also discloses a cell formation system, comprising an auxiliary device for cell formation as described in any of the preceding claims, and:

[0039] The formation frame has two vertically arranged positioning frames facing each other. Each of the two positioning frames has a vertically rotatable swing disk on its facing side. The positioning frame is equipped with a motor for driving the swing disk to rotate. The top of the swing disk is equipped with two vertical top connecting rods and the bottom is equipped with two vertical bottom connecting rods.

[0040] A top plate and a bottom plate are provided. The top plate is fixedly connected to the top of all the top connecting rods, and the bottom plate is fixedly connected to the bottom of all the bottom connecting rods. A clamping cylinder is vertically provided on the top plate. A clamping plate is provided on the piston rod of the clamping cylinder. All the top connecting rods pass through the clamping plate, and the outer wall of the top connecting rod is attached to the clamping plate. A clamping block is provided at the bottom of the clamping plate.

[0041] Two limiting posts are provided between one side edge of the top plate and the bottom plate. The limiting posts are used to limit all the forming plates. The side of the forming frame away from the limiting posts is open.

[0042] A transfer plate is used to support several layers of formation plates. Anti-fall frames are provided on one side or adjacent sides of the top of the transfer plate, and the anti-fall frames are lower than the formation plates located at the top. Several spaced support bars are arranged parallel to each other at the bottom of the transfer plate. Each formation plate has at least two anti-sway posts at the top and at least two anti-sway cylinders at the bottom. The tops of the lower anti-sway posts are attached to the inner walls of the upper anti-sway cylinders. The tops of the anti-sway posts are higher than the corresponding action plates, and the bottoms of the anti-sway cylinders are higher than the bottoms of the corresponding pressure bars.

[0043] Compared with existing technologies, this invention provides a cell formation system and its auxiliary devices. After a stack of multi-layered formation plates is charged, heated, and pressurized, a forklift transfers the transfer plate and the multi-layered formation plates together to the side of the support platform. At this time, the worker manually transfers the top formation plate to the top of the loading and unloading plate. Then, the lifting frame descends and opens all the charging clamps, so that all the cells are ready to be picked up. Then, the transfer frame moves above the loading and unloading plate and descends, so that each cell has at least one suction cup (i.e., a first suction cup or a second suction cup, wherein the first and second suction cups are both commercially available flexible rubber or other conventional materials; at the same time, the first suction tube, the second suction tube, and the negative pressure pump used to apply negative pressure to the first and second suction tubes are all commercially available) for adsorption. Then, the transfer frame rises and moves toward the finished product plate. During the movement, the distance between the first adsorption seats decreases, the distance between the second adsorption seats decreases, and the sliding frame moves towards the first sliding groove, thereby reducing the distance between all the battery cells and the airbags that wrap the battery cells. Preferably, the airbags in the same column are in a close fit, and the airbags in different columns are in a close fit (at this time, the battery cells in different columns are in a close fit between airbags) or the electrode tabs of the battery cells are in a close fit (at this time, the battery cells in different columns are in a close fit between electrode tabs) or the airbags in the previous column are in a close fit with the electrode tabs in the adjacent column (at this time, the sorting direction of different columns is the same). The purpose is to directly reduce the distance between the battery cells, and preferably reduce it to a distance that is easy to store or transfer (i.e., transfer to the next process for heat sealing of the airbags).

[0044] The transfer frame then moves to the top of the processing plate, which has neatly arranged battery cells (these cells can be arranged manually by workers to save time, arranged by a robotic arm, or arrive with the cells already arranged). The first and second suction cups then stably pick up the corresponding battery cells and transfer them to the formation plate. Throughout this process, the charging clamps on the formation plate remain open, waiting for new battery cells to be placed. After the new battery cells are placed, the lifting frame rises, and the charging clamps automatically clamp the two tabs of the battery cells. The worker then transfers the formation plate to the side transfer plate.

[0045] During the formation process, the battery cells and airbags need to maintain a certain distance. However, the battery cells to be processed may have small gaps or be in a close fit. At the same time, the formed battery cells are preferably sent out in an orderly manner. Therefore, by using the transfer frame, first adsorption seat, second adsorption seat, first suction cup, second suction cup, third driving mechanism, fourth driving mechanism and fifth driving mechanism of this application, all the formed battery cells can be transferred to the finished product board in an orderly manner at one time, and the battery cells on the finished product board are spaced small or close to each other. Similarly, all the battery cells to be formed can be transferred from the processing board to the formation board at one time, which greatly improves the efficiency of removing and placing battery cells, and also saves the time of placing battery cells on the loading and unloading board and on the finished product board, resulting in better production effect.

[0065] Example 1

[0066] An auxiliary device for cell formation, such as Figures 1 to 14 As shown, it includes:

[0067] Support platform 1, which is horizontal, and the top of the support platform 1 is sequentially provided with a plate to be processed 2, a loading and unloading plate 3 and a finished plate 4;

[0068] The lifting frame 5 is located above the loading and unloading plate 3, and the loading and unloading plate 3 is provided with a first driving mechanism for lifting the lifting frame 5.

[0069] The transfer frame 6 and the second drive mechanism for moving and raising the transfer frame 6 are provided. A long strip-shaped first slide groove 7 and a rectangular second slide groove 8 are vertically opened through the transfer frame 6. Several first suction seats 9 are horizontally movably arranged in the first slide groove 7. Each first suction seat 9 has a first suction cup 10 at its bottom and a first suction tube 11 connected to its top. A rectangular sliding frame 12 is horizontally movably arranged in the second slide groove 8. Several second suction seats 13 are horizontally movably arranged in the sliding frame 12. Each second suction seat 13 has a second suction cup 14 at its bottom and a second suction tube connected to its top. The movement direction of the sliding frame 12 is perpendicular to the movement direction of the first suction seats 9, and the movement direction of the first suction seats 9 is parallel to the movement direction of the second suction seats 13.

[0070] The system comprises a third driving mechanism, a fourth driving mechanism, and a fifth driving mechanism. The third driving mechanism is used to drive the first adsorption seat 9 to move, the fourth driving mechanism is used to drive the sliding frame 12 to move, and the fifth driving mechanism is used to drive the second adsorption seat 13 to move.

[0071] The loading and unloading plate 3 is hollow. The first driving mechanism includes several cylinders vertically arranged in the loading and unloading plate 3. The piston rods of all the cylinders move vertically through the loading and unloading plate 3, and the piston rods of the cylinders are connected to the bottom of the lifting frame 5. The lifting frame 5 is shaped like a square, a sun, or an eye.

[0072] The top of the loading and unloading plate 3 is used to support a chemical forming plate 15, and the top of the loading and unloading plate 3 is horizontally provided with a U-shaped first limiting member 16 for limiting the chemical forming plate 15. The inner side and both ends of the chemical forming plate 15 are attached to the inner wall of the first limiting member 16.

[0073] The top of the plate to be processed 2 is horizontally provided with a second U-shaped limiting member 17, and the top of the finished plate 4 is horizontally provided with a third U-shaped limiting member 18. The opening directions of the first limiting member 16, the second limiting member 17, and the third limiting member 18 are in the same direction. The top of the plate to be processed 2 is horizontally provided with a support member 19, the inner side and both ends of the support member 19 are attached to the inner wall of the second limiting member 17. The top of the finished plate 4 is horizontally provided with a finished product support member 20. The support member 19 is used to support the battery cell to be processed, and the finished product support member 20 is used to support the battery cell after formation. The distance between the battery cells on the support member 19 and the distance between the battery cells on the finished product support member 20 are both smaller than the distance between the battery cells on the formation plate 15.

[0074] The top of the support platform 1 is vertically provided with several guide members 21, each with an L-shaped cross-section. The outer sides of the four corners of the plate to be processed 2 and the finished plate 4 are vertically movable and fit against the inner wall of one of the guide members 21. The top of the support platform 1 is vertically provided with several first elastic members 22, and the bottom of the plate to be processed 2 and the finished plate 4 are also provided with several first elastic members 22. The support member to be processed 19 and the finished support member 20 are both open-to-the-upward cover-shaped. The first suction tube 11 and the second suction tube both include a rigid tube and a flexible tube (not shown in the figure). The rigid tube moves vertically through the corresponding first adsorption seat 9 or second adsorption seat 13. The outer wall of the rigid tube is connected to the bottom of the first adsorption seat 9 or the second adsorption seat 13 by a spring, allowing the rigid tube to have a certain degree of vertical movement. Thus, even if the height of the battery cell changes within the support 19 to be processed or the finished support 20, the spring's elastic deformation can compensate for the height change when the first suction tube 11 and the second suction tube place the battery cell into the finished support 20 or remove it from the support 19 to be processed, allowing for normal placement or removal of the battery cell. Furthermore, depending on the actual situation, position sensors can be installed above the finished support 20 and the support 19 to be processed, and the depths of the first vertical groove 40 and the third vertical groove 42 can be set to be relatively deep. This increases the stroke during battery cell placement and removal, ensuring stable placement and removal even if the battery cell height changes. In practical use, one or more main suction tubes can be installed, and each suction tube can provide negative pressure to multiple first suction tubes 11 and / or second suction tubes. A small air pump or switch can be connected to the first suction tube 11, the second suction tube, or the main suction tube. When the battery cell needs to be placed down after being transferred to the loading / unloading plate 3 or the finished product plate 4, the switch can be opened after the negative pressure in the first suction cup 10 and the second suction cup 14 disappears, facilitating the separation of the battery cell from the corresponding suction cup. Alternatively, the air pump can apply a small airflow, which is blown out through the first suction cup 10 and the second suction cup 14, thereby accelerating the separation of the battery cell from the first suction cup 10 and the second suction cup 14. Or, the first suction cup 10 and the second suction cup 14 have a certain elasticity. The negative pressure generated when adsorbing the battery cell can cause the battery cell to press the first suction cup 10 and the second suction cup 14 until they are deformed. Then, after the negative pressure in the first suction cup 10 and the second suction cup 14 disappears, the first suction cup 10 and the second suction cup 14 will elastically rebound, thereby accelerating the separation of the battery cell from the first suction cup 10 and the second suction cup 14.

[0075] The bottom of the formation plate 15 has two parallel pressure bars 23 horizontally arranged, and the top has two parallel heating bars 24 horizontally arranged. The length direction of the heating bars 24 is parallel to the length direction of the pressure bars 23. Each heating bar 24 has several spaced charging clips on both sides. The charging clip includes a lower clamping plate 25 that is horizontally attached to the formation plate 15. The top of the lower clamping plate 25 has two hinge seats 26 vertically arranged. A hinge post 27 is horizontally rotatably arranged between the two hinge seats 26. One side of the hinge post 27 has an upper clamping plate 28 located above the lower clamping plate 25, and the other side has a linkage part 29. A linkage hole 30 with a long strip or waist-shaped longitudinal section is opened horizontally through the linkage part 29.

[0076] The charging clamp body is made of insulating material, but the top of the lower clamping plate 25 has a copper sheet, and the forming plate 15 has embedded wires or other structures for charging the copper sheet. The heating strip 24 also has an electric heating wire or other structure that can heat up when energized. Each forming plate 15 has an electrical connector on its side. After all the forming plates 15 are transferred to the forming rack 86, the electrical connectors are connected to an external plug or other connector, allowing for subsequent charging and heating of the battery cells. Pressurization of the battery cells is achieved through a clamping cylinder 93. When the clamping cylinder 93 presses the battery cells, the clamping block 95 presses the top battery cells, while the lower battery cells are pressurized by the pressure bar 23. The pressure bar 23 and heating strip 24 thicken the forming plate 15, ensuring that the action plate 33, upper clamping plate 28, etc., are not affected by the forming plate 15 during pressurization and charging, thus guaranteeing charging stability.

[0077] The top of the formation plate 15 is vertically provided with several guide cylinders 31. Each guide cylinder 31 has a guide rod 32 vertically and movably arranged inside it. The outer wall of the guide rod 32 is movably attached to the inner wall of the corresponding guide cylinder 31 and moves through the formation plate 15. The top of all the guide rods 32 is horizontally provided with an action plate 33. The action plate 33 is provided with two action ears 34 on the side near the upper clamping plate 28. A cylindrical action column 35 is horizontally arranged between the two action ears 34. The action column 35 is movably attached to the inner wall of the linkage hole 30. A second elastic member 36 that is continuously compressed is vertically arranged between the bottom of the action plate 33 and the top of the formation plate 15. An insulating member 37 is vertically arranged in the middle of the lower clamping plate 25. An opening for the insulating member 37 to pass through is provided on the upper clamping plate 28.

[0078] All the aforementioned action plates 33 are located below the lifting frame 5. When the lifting frame 5 is higher than the action plate 33, the upper clamping plate 28 and the lower clamping plate 25 clamp the electrode tab of the battery cell. When the lifting frame 5 drives the action plate 33 downward, the action plate 33 drives the lower clamping plate 25 to rotate upward through the action column 35, so that the electrode tab of the battery cell can move vertically downward to fit against the lower clamping plate 25.

[0079] The second drive mechanism includes:

[0080] A positioning plate 38 is vertically disposed on the top of the support platform 1. A horizontal groove 39 is formed on the positioning plate 38.

The anti-detachment disc 56 is movably attached to the drive member 45 (in this way, it can bear the torque generated by the transfer rod 49, which can not only protect the passive cylinder 51 and other structures, but also reduce the friction between the passive cylinder 51, the passive seat 50 and other structures). The horizontal groove 39, the first vertical groove 40, the second vertical groove 41, the third vertical groove 42, the first drive groove 46 and the second drive groove 47 are all provided in two sets.

[0090] The fourth driving mechanism includes a receiving groove formed in the inner wall of the second slide groove 8. A support rod 66 is horizontally arranged in the receiving groove. The support rod 66 moves through the sliding frame 12. A fourth elastic element 67, which is continuously compressed, is movably sleeved on the outer wall of the support rod 66.

A first stabilizing seat 72 is arranged on the top of each first adsorption seat 9. A first stabilizing cable 73 is arranged between two adjacent first stabilizing seats 72. When the chip on the formation plate 15 is picked up, all the first stabilizing cables 73 are straight. The free end of the first termination member 63 is separated from the adjacent first adsorption seat 9.

[0092] The fifth drive mechanism includes a second motor frame 74 disposed at one end of the sliding frame 12 and a second take-up motor 75 vertically disposed on the second motor frame 74. The first take-up motor 60 and the second take-up motor 75 are located on the same side of the transfer frame 6. A second take-up reel is horizontally disposed on the output shaft of the second take-up motor 75. A second anti-detachment plate with a diameter larger than the second take-up reel is disposed at the top and bottom of the second take-up reel.

The free end of the second take-up cable 76 is connected to the second connecting seat 77.

[0093] The two second adsorption seats 13 located at the edge abut against the inner walls of both ends of the sliding frame 12. A fifth elastic member 78 that is continuously compressed is horizontally arranged between two adjacent second adsorption seats 13. Except for the second adsorption seat 13 connected to the second connecting seat 77, the other second adsorption seats 13 are horizontally provided with a second termination member 79, and the second termination member 79 is connected to the side of the corresponding second adsorption seat 13 away from the second winding motor 75.

[0095] The present invention also provides a cell formation system, such as Figures 15 to 17 As shown, it includes an auxiliary device for cell formation as described in any of the preceding claims, and:

[0096] The formation frame 86 has two vertically arranged positioning frames 87 facing each other. Each of the two positioning frames 87 has a vertically rotatable swing disk 88 on its facing side. The positioning frame 87 is equipped with a motor for driving the swing disk 88 to rotate. The top of the swing disk 88 is provided with two vertical top connecting rods 89, and the bottom is provided with two vertical bottom connecting rods 90.

[0097] A top plate and a bottom plate are provided. The top plate is fixedly connected to the top of all the top connecting rods 89, and the bottom plate is fixedly connected to the bottom of all the bottom connecting rods 90. A pressing cylinder 93 is vertically provided on the top plate 91. A pressing plate 94 is provided on the piston rod of the pressing cylinder 93. All the top connecting rods 89 pass through the pressing plate 94, and the outer wall of the top connecting rod 89 is attached to the pressing plate 94. A pressing block 95 is provided at the bottom of the pressing plate 94.

[0098] Limiting posts 96: Two limiting posts 96 are provided between one edge of the top plate 91 and the bottom plate 92 (for supporting the support bar 99). The limiting posts 96 are used to limit all the forming plates 15. The side of the forming frame 86 away from the limiting posts 96 is open.

[0099] A transfer plate 97 supports several layers of formation plates 15. Anti-fall frames 98 are provided on one side or adjacent sides of the top of the transfer plate 97, and the anti-fall frames 98 are lower than the formation plates 15 located at the top. Several spaced support bars 99 are arranged parallel to each other at the bottom of the transfer plate 97. Each formation plate 15 has at least two anti-sway posts 100 at its top and at least two anti-sway cylinders 101 at its bottom. The tops of the lower anti-sway posts 100 are attached to the inner walls of the upper anti-sway cylinders 101. The tops of the anti-sway posts 100 are higher than the corresponding action plate 33, and the bottoms of the anti-sway cylinders 101 are higher than the bottoms of the corresponding pressure bars 23.

[0100] This invention provides a battery cell formation system and its auxiliary device. After a stack of multi-layered formation plates 15 has been charged, heated, and pressurized, a forklift transfers the transfer plate 97 and the multi-layered formation plates 15 together to the side of the support platform 1. At this time, the worker manually transfers the top formation plate 15 to the top of the loading and unloading plate 3. Then, the lifting frame 5 descends and opens all the charging clamps, so that all the battery cells are in a ready-to-remove state. Then, the transfer frame 6 moves above the loading and unloading plate 3 and descends, so that each battery cell has at least one suction cup (i.e., the first suction cup 10 or the second suction cup 14, wherein the first suction cup 10 and the second suction cup 14 are both commercially available flexible rubber or other conventional material suction cups; at the same time, the first suction tube 11, the second suction tube, and the negative pressure pump used to apply negative pressure to the first suction tube 11 and the second suction tube are all commercially available) for adsorption. Then, the transfer frame 6 rises and moves toward the finished product plate 4. During the movement, the distance between the first adsorption seats 9 and the distance between the second adsorption seats 13 decreases. At the same time, the sliding frame 12 moves towards the first sliding groove 7, which reduces the distance between all the battery cells and the airbags that wrap the battery cells. Preferably, the airbags in the same column are in a close fit, and the airbags in different columns are in a close fit (at this time, the battery cells in different columns are in a close fit between airbags) or the electrode tabs of the battery cells are in a close fit (at this time, the battery cells in different columns are in a close fit between electrode tabs) or the airbags in the previous column are in a close fit with the electrode tabs in the adjacent column (at this time, the sorting direction of different columns is the same). The purpose is to directly reduce the distance between the battery cells, and preferably reduce it to a distance that is easy to store or transfer (i.e., transfer to the next process for heat sealing of the airbags).

[0101] Then, the transfer frame 6 moves to the top of the processing plate 2, where the processing plate 2 has neatly arranged battery cells (which can be arranged manually by workers beforehand to save time; arranged by a robot; or the incoming material already has the battery cells arranged). The first suction cup 10 and the second suction cup 14 can then stably attract the corresponding battery cells and transfer them to the formation plate 15. Throughout this process, the charging clamp on the formation plate 15 remains open, waiting for the new battery cells to be placed. After the new battery cells are placed, the lifting frame 5 rises, and the charging clamp automatically clamps the two tabs of the battery cells. Then, the worker transfers the formation plate 15 to the side transfer plate 97.

[0102] During the formation process, the battery cells and airbags need to maintain a certain distance. However, the battery cells to be processed may have small gaps or be in a close fit. At the same time, the formed battery cells are preferably arranged in an orderly manner and sent out. Therefore, by using the transfer frame 6, the first adsorption seat 9, the second adsorption seat 13, the first suction cup 10, the second suction cup 14, the third driving mechanism, the fourth driving mechanism, and the fifth driving mechanism of this application, all the formed battery cells can be transferred to the finished product plate 4 in an orderly manner at one time, and the spacing between the battery cells on the finished product plate 4 is small or they are in close fit with each other. Similarly, all the battery cells to be formed can be transferred from the processing plate 2 to the formation plate 15 at one time for placement, thereby greatly improving the efficiency of removing and placing battery cells, and also saving the time of placing battery cells on the loading and unloading plate 3 and the finished product plate 4, resulting in better production effect.

[0103] The worker places the formed plate 15, now fully formed, on top of the loading / unloading plate 3, ensuring that the inner side and both ends of the formed plate 15 abut against the inner wall of the first limiting member 16, thus fixing the position of the formed plate 15. Then, the cylinder lowers the height of the lifting frame 5, causing all the action plates 33 to be subjected to downward pressure from the lifting frame 5. Simultaneously, the height of the guide rod 32, action plates 33, and action column 35 is lowered, further compressing the second elastic member 36. At this time, the action column 35 drives the linkage part 29 downward through the inner wall of the linkage hole 30, causing the upper clamping plate 28 to swing upward. When the lifting frame 5 descends to its lowest height, the upper clamping plate 28 has rotated a large angle, preferably around 90°, at which angle the battery cell and electrode tabs can move smoothly vertically.

[0104] The first drive groove 46 and the second drive groove 47 are both inclined and form an upward-opening V-shape. The first vertical groove 40, the second vertical groove 41, and the third vertical groove 42 are all vertical. At the same time, the transfer rod 49 is simultaneously acted upon by the first drive groove 46 or the second drive groove 47 and the first vertical groove 40 or the second vertical groove 41 or the third vertical groove 42. This allows the transfer rod 49 to move to any position of the horizontal groove 39, the first vertical groove 40, the second vertical groove 41, and the third vertical groove 42. Furthermore, the first vertical groove 40, the second vertical groove 41, and the third vertical groove 42 all move vertically, ensuring that the first suction cup 10 and the second suction cup 14 can stably act on the corresponding battery cells.

[0105] The starting position is set at the middle of the horizontal groove 39 between the first vertical groove 40 and the second vertical groove 41. Assuming... Figure 1The slot on the left is the first drive slot 46, and the slot on the right is the second drive slot 47. At this time, the transfer rod 49 is located at the top and starting position of the second drive slot 47 (this is the assumed initial state). If the transfer rod 49 needs to move into the first vertical slot 40, the drive member 45 only needs to move to the left until the left end of the horizontal slot 39, and then the drive member 45 moves to the right a short distance. At this time, the transfer rod 49 can move down along the second drive slot 47 until the first suction cup 10 and the second suction cup 14 are attracted to the corresponding battery cells.

[0106] Then the drive unit 45 moves to the right, and the transfer rod 49 rises along the first drive groove 46 to the left end of the horizontal groove 39; then the drive unit 45 continues to move to the right until the transfer rod 49 moves to the top of the second vertical groove 41. At this time, the drive unit 45 slowly moves to the left (to prevent the transfer rod 49 from moving back to the horizontal groove 39), so that the transfer rod 49 can move down along the second vertical groove 41 until all the cells are placed on the formation plate 15.

[0107] Then, the drive unit 45 moves to the left (it can also move to the right depending on the actual situation, both can be implemented through the program), and the second drive groove 47 raises the transfer rod 49 and makes the transfer rod 49 move to the starting position for standby. After the next formation plate 15 is fixed on the loading and unloading plate 3, the drive unit 45 moves to the right, making the transfer rod 49 move into the second vertical groove 41 again, and making the first suction cup 10 and the second suction cup 14 attract the corresponding cells. Then the drive unit 45 continues to move to the right, and the first drive groove 46 drives the transfer rod 49 to rise, and makes the transfer rod 49 move into the horizontal groove 39, until the transfer rod 49 moves from the horizontal groove 39 into the third vertical groove 42 (wherein, when the transfer rod 49 moves to the top of the third vertical groove 42, the drive seat 44 will move to the left a certain distance), and place the formed cells onto the finished product support 20.

[0108] Then, the drive unit 45 moves to the left, and the second drive groove 47 raises the transfer rod 49 into the horizontal groove 39. The rod then moves along the horizontal groove 39 at a relatively fast speed, allowing it to directly cross the second vertical groove 41 (where the connection between the second vertical groove 41 and the horizontal groove 39 is rounded or chamfered to facilitate direct crossing). Finally, it moves directly back to the starting position, returning to the assumed initial state, thus completing one cycle. Although the process is described in detail, initially, simply reciprocating the drive seat 44 via the drive screw 54 is sufficient to enable the transfer frame 6 to perform multiple lifting and lowering functions.

[0109] Furthermore, the transfer base 48 has two or more transfer rods 49, and the side of the passive base 50 is also limited by the passive cylinder 51, so that the transfer frame 6 can only move vertically and steadily without changing angle, thus ensuring that the battery cell can be moved stably. When the transfer frame 6 is moving, the anti-rotation part 52 can also drive the passive cylinder 51 to move horizontally, and during this process, the passive base 50 is limited by the auxiliary rod, which further ensures the positional and angular stability of the passive cylinder 51, and also ensures the angular stability of the transfer frame 6.

[0110] As more battery cells are removed from the support member 19, the height of both the plate to be processed 2 and the support member 19 increases under the elastic force of the first elastic member 22, making it easier for them to be attracted by the first suction cup 10 and the second suction cup 14. Conversely, as the number of battery cells in the finished support member 20 increases, the first elastic member 22 is further compressed, thereby reducing the height of the finished support member 20, making it easier for the first suction cup 10 and the second suction cup 14 to place the battery cells.

[0111] After the transfer frame 6 picks up the battery cells on the forming plate 15, the first take-up motor 60 drives the first take-up reel to rotate and wind the first take-up cable 61 (which has a certain strength, but can also undergo a certain deformation, so that it can drive the first adsorption seat 9 and the sliding frame 12 to move, and at the same time prevent the first take-up motor 60 from being overloaded; when the sensor on the transfer frame 6 senses that the first connecting seat 64 has moved to the designated position, the first take-up motor 60 stops running and locks), thereby driving the first adsorption seat 9 connected to the first connecting seat 64 to move toward the first take-up motor 60, until finally all the sides of the first adsorption seats 9 abut against the free end of the adjacent first termination member 63.

[0112] Furthermore, when the first connecting seat 64 is in motion, it simultaneously drives the sliding frame 12 towards the first adsorption seat 9 via the connecting cable 70. When the first connecting seat 64 reaches its maximum stroke, the sliding frame 12 also reaches its maximum stroke. At this point, the sliding frame 12 is continuously supported by the fourth elastic element 67, thus maintaining its positional stability. Simultaneously, the second winding motor 75, via the second winding cable 76, causes all the second adsorption seats 13 to move to their designated positions (i.e., all movable second adsorption seats 13 abut against the free end of the adjacent second termination element 79). Therefore, at this time, the cells in the same row are close to each other, and the cells in different rows are also close to each other, allowing them to be stably placed within the finished product support 20, and ensuring stability after placement.

[0113] After maintaining the above state, the battery cell inside the support 19 to be processed is picked up. After the new battery cell is moved above the formation plate 15, the first winding motor 60 and the second winding motor 75 release the first winding cable 61 and the second winding cable 76 respectively. Under the elastic force of the third elastic member 62, the fourth elastic member 67 and the fifth elastic member 78, all the first adsorption seats 9, the sliding frame 12 and the second adsorption seats 13 move to the designated positions. Moreover, through the action of the first stabilizing seat 72, the first stabilizing cable 73 (preferably a rope with very little or no elasticity), the second stabilizing seat 81 and the second stabilizing cable 82 (preferably a rope with very little or no elasticity), the first adsorption seats 9 and the second adsorption seats 13 can maintain the relative positional stability of each other, ensuring the positional stability of the battery cell placed on the formation plate 15, and also ensuring the stability of the subsequent picking up of the battery cell from the formation plate 15.

[0114] Furthermore, the first stabilizing rod 71 guides the first adsorption seat 9 and the first termination member 63, ensuring the stability of the first adsorption seat 9. Similarly, the second stabilizing rod 80 guides the second adsorption seat 13 and the second termination member 79, ensuring the stability of the second adsorption seat 13. The first and second stabilizing rods 71 ​​and 80 also support the third elastic member 62 and the fifth elastic member 78 respectively, preventing lateral deformation. The support rod 66 supports the fourth elastic member 67. This structure ensures the service life of the third elastic member 62, the fourth elastic member 67, and the fifth elastic member 78. Depending on the actual situation, ball bearings or similar components can be installed in the guide grooves 58 or outside the guide bars 57 of each structure to reduce movement resistance.

[0115] After the formation plate 15 with battery cells is repositioned onto the transfer plate 97, the upper and lower formation plates 15 are connected by anti-sway pillars 100 and anti-sway cylinders 101, ensuring the positional stability of the formation plate 15. Then, the forklift (purchased commercially) lifts the transfer plate 97 through the spacing between the support bars 99 and places the support bars 99 onto the bottom plate 92, with the anti-fall frame 98 and limit posts 96 located on both sides of the formation plate 15. Then, the clamping cylinder 93 drives the clamping plate 94 downwards, pressing it against all the battery cells at the top via the clamping block 95. Afterwards, the motor drives the swing plate to rotate 90 degrees, positioning the limit posts 96 below the formation plate 15, providing support for the formation plate 15, which is then used for subsequent heating and charging operations. During this pressurization process, because the formation plate 15 is horizontal, the pressure on the battery cells at different positions is relatively similar, thus ensuring the production stability of the battery cells.

[0116] Example 2

[0117] The difference from Example 1 is that, as Figure 18As shown, the fifth driving mechanism includes an L-shaped synchronizing member 83 disposed on the top of the second adsorption seat 13. The top of each of the first adsorption seats 9 is vertically provided with a synchronizing rod 84. The top of each synchronizing rod 84 is horizontally provided with a cylindrical synchronizing cylinder 85. The top of each synchronizing member 83 horizontally moves through one of the synchronizing cylinders 85, and the outer wall of the synchronizing member 83 is respectively movably attached to the inner wall of the corresponding synchronizing cylinder 85.

[0118] At this point, the second motor frame 74, the second take-up motor 75, and the fifth elastic element 78 are not required to drive the movement of the second adsorption seats 13. Instead, this is achieved through the synchronization element 83 and the synchronization cylinder 85. That is, when the first take-up motor 60 starts, the first adsorption seat 9 can be normally retracted and the sliding frame 12 can be pulled closer. At the same time, the action of the inner wall of the synchronization cylinder 85 causes the second adsorption seats 13 to move closer to each other synchronously. When the first adsorption seat 9 reaches the designated position, all the second adsorption seats 13 also reach the designated position. The synchronization element 83 is relatively high and does not interact with the first steering wheel 68, the second steering wheel 69, or other structures.

[0119] Example 3

[0120] The difference from Embodiment 1 is that the plate to be processed 2 and the finished plate 4 are both fixedly connected to the support platform 1, the support member to be processed 19 and the finished support member 20 are both flat, and the top of the support member to be processed 19 and the finished support member 20 are provided with an anti-slip layer.

[0121] The unprocessed support 19 and the finished product support 20 are used for transferring battery cells. Multiple flat unprocessed support 19s are located outside the support platform 1. One or a few workers can place the required battery cells on these support 19s. Since the battery cells are close together, this placement is relatively easy and ensures quality. After the finished battery cells are placed on the finished product support 20, the worker simply moves the finished product support 20 to the side container and tilts it to transfer the battery cells one by one into the container. The protective layers on the unprocessed support 19 and the finished product support 20 prevent the battery cells from shifting during the transfer process, ensuring the worker can push the battery cells off the finished product support 20.
