Description

Technical Field

[0001] This invention relates to the field of battery cell stacking technology, and in particular to a battery cell horizontal stacking device and a double-layer processing platform. Background Technology

[0002] Cell stacking is a crucial step in assembling a battery module. Traditional stacking involves bonding several cells horizontally, one by one, towards the clamp holding the first end plate. However, traditional cell clamps cannot properly position and hold the last end plate. Therefore, after stacking a specified number of cells, the cell clamp must be replaced with a last end plate clamp, or the product must be transferred to another station for last end plate assembly. This process not only reduces stacking efficiency but also, because the last end plate remains unassembled for an extended period, the stacked cells are prone to positional shifts under elastic restoring forces, ultimately affecting the dimensional accuracy of the battery module. Summary of the Invention

[0003] The present invention aims to solve the problem of low efficiency in battery cell stacking.

[0004] To solve the above-mentioned technical problems, the first technical solution adopted by the present invention is: a battery cell horizontal stacking device, including a battery cell clamp and a tail end plate support block; The battery cell clamp includes a first push plate, the clamping end of the battery cell clamp is located in front of the front of the first push plate, and a first pressure block is provided on the battery cell clamp; The tail end plate support block is movably positioned below the cell clamp and can be moved to below the clamping end of the cell clamp. When the tail plate support block moves to below the clamping end of the cell clamp, the first pressure block can move toward the support surface of the tail plate support block.

[0005] Furthermore, the battery cell clamp also includes a first pneumatic gripper, a drive cylinder, and a photoelectric sensor; the first push plate is connected to the cylinder body of the first pneumatic gripper, the movable end of the drive cylinder is connected to the tail end plate support block, and the photoelectric sensor is communicatively connected to the first pneumatic gripper and the drive cylinder.

[0006] Furthermore, the battery cell clamp also includes a push cylinder and a pressure sensor. The movable end of the push cylinder is connected to the first push plate, and the pressure sensor is disposed on the movable end of the push cylinder.

[0007] Furthermore, the battery cell clamp also includes a first rotary cylinder, the movable end of which is connected to a first pressure block.

[0008] Furthermore, the aforementioned battery cell horizontal stacking device also includes an end plate clamp and a support plate. The end plate clamp and the battery cell clamp are respectively disposed at opposite ends of the support plate. The support plate is provided with a driver, which is used to adjust the distance between the end plate clamp and the battery cell clamp.

[0009] Furthermore, the end plate clamp includes a second push plate, a second pneumatic gripper, a first end plate support block, and a second pressure block; the second push plate is connected to the cylinder of the second pneumatic gripper, the gripping end of the second pneumatic gripper is located in front of the plate face of the second push plate, the first end plate support block is located below the gripping end of the second pneumatic gripper, and the second pressure block can move toward the support surface of the first end plate support block.

[0010] Furthermore, the end plate clamp also includes a second rotary cylinder, the movable end of which is connected to the second pressure block.

[0011] Furthermore, the driver includes a first motor and a lead screw, the output shaft of the first motor is drivenly connected to the lead screw, and the cell clamp and / or end plate clamp are threadedly connected to the lead screw.

[0012] To solve the above-mentioned technical problems, the second technical solution adopted by the present invention is: a double-layer processing platform, including a base, a frame and a battery cell horizontal stacking device. The base has an end plate station and a battery cell station. The frame reciprocates between the end plate station and the battery cell station. The battery cell horizontal stacking device is the battery cell horizontal stacking device described in the first technical solution above. The battery cell horizontal stacking device is provided on both the base and the frame. The battery cell horizontal stacking device provided on the base can reciprocate between the end plate station and the battery cell station.

[0013] Furthermore, the battery cell horizontal stacking device provided on the base and the linear reciprocating device provided on the frame for reciprocating between the end plate station and the battery cell station are both provided.

[0014] The beneficial effects of this invention are as follows: By adding a first push plate and a tail plate support block movable below the clamping end to the cell clamp, when the tail plate needs to be assembled, a robotic arm or other transfer device sends the tail plate into the cell clamp. The first push plate and the tail plate support block can be used to adjust its posture. Then, the clamping end of the cell clamp holds the tail plate and aligns it on the tail plate support block. Next, a first pressing block presses the tail plate firmly onto the tail plate support block. The clamping end of the cell clamp releases the tail plate, allowing the gripping end of the robotic arm or other transfer device to smoothly exit the cell clamp. After the gripping end of the robotic arm or other transfer device exits, the clamping end of the cell clamp re-clamps the tail plate, allowing the cell clamp to be used directly for tail plate assembly, thereby improving product stacking efficiency and effectively ensuring the assembly accuracy of the battery module.

Detailed Implementation

[0016] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the present invention provides a battery cell horizontal stacking device, including a battery cell clamp 1 and a tail end plate support block 2; the battery cell clamp 1 includes a first push plate 11, the clamping end of the battery cell clamp 1 is located in front of the front of the first push plate 11, and a first pressure block 12 is provided on the battery cell clamp 1; the tail end plate support block 2 is movably disposed below the battery cell clamp 1, and can move to below the clamping end of the battery cell clamp 1; when the tail end plate support block 2 moves to below the clamping end of the battery cell clamp 1, the first pressure block 12 can move toward the support surface of the tail end plate support block 2.

[0018] Working principle: By adding a first push plate 11 and a tail plate support block 2 that can be moved below the clamping end to the cell clamp 1, when the tail plate needs to be assembled, a robotic arm or other transfer device sends the tail plate into the cell clamp 1. The first push plate 11 and the tail plate support block 2 can be used to adjust its posture. Then, the clamping end of the cell clamp 1 clamps the tail plate and achieves centering and positioning on the tail plate support block 2. Next, the first pressure block 12 presses and fixes the tail plate on the tail plate support block 2. The clamping end of the cell clamp 1 releases the tail plate so that the gripping end of the robotic arm or other transfer device can smoothly exit the cell clamp 1. After the gripping end of the robotic arm or other transfer device exits, the clamping end of the cell clamp 1 re-clamps the tail plate, so that the cell clamp can be directly used for the assembly of the tail plate, thereby improving the product stacking efficiency and effectively ensuring the assembly accuracy of the battery module.

[0019] Meanwhile, during the battery cell stacking operation, the tail end plate support block 2 moves away from the clamping end of the battery cell clamp 1 to avoid the tail end plate support block 2 affecting the normal clamping of the battery cell; the battery cell clamp 1 clamps the battery cell and moves it towards the end plate clamp 3. After moving to the designated position, the battery cell clamp 1 releases the battery cell so that the battery cell falls on the support plate 4. Then the battery cell clamp 1 re-clamps the battery cell for centering. Then the battery cell clamp 1 releases the battery cell. Finally, the first push plate 11 pushes the battery cells to stack.

[0020] In some embodiments, the clamping ends of the cell clamp 1 can be multiple and arranged sequentially in front of the first push plate 11. However, in order to ensure the accuracy of the first push plate 11 in pushing the cells for stacking, the number of clamping ends of the cell clamp 1 is two to three, thereby improving the stacking efficiency of the product.

[0021] In some implementations, please refer to Figures 2 to 4 As shown, the battery cell clamp 1 further includes a first pneumatic gripper 13, a drive cylinder 14, and a photoelectric sensor 15; the first push plate 11 is connected to the cylinder body of the first pneumatic gripper 13, the movable end of the drive cylinder 14 is connected to the tail end plate support block 2, and the photoelectric sensor 15 is communicatively connected to the first pneumatic gripper 13 and the drive cylinder 14. The photoelectric sensor 15 detects whether the battery cell or the tail end plate is in place, thereby activating the first pneumatic gripper 13 and / or the drive cylinder 14 to perform the operation.

[0022] In some implementations, please refer to Figure 2 As shown, the cell clamp 1 also includes a pushing cylinder 16 and a pressure sensor 17. The movable end of the pushing cylinder 16 is connected to the first pushing plate 11, and the pressure sensor 17 is disposed on the movable end of the pushing cylinder 16. During the stacking process, after the cell clamp 1 moves the cell or end plate to the designated position, the pushing cylinder 16 drives the first pushing plate 11 to apply stacking pressure to the cell or end plate. At the same time, the pressure sensor 17 monitors the compression pressure in real time, so that the clamping force during the stacking process can be precisely controlled, thereby ensuring that the tape bonding between cells and between cells and end plates is firm and reliable, effectively improving the stacking quality and consistency.

[0023] In some implementations, please refer to Figure 2 As shown, the battery cell clamp 1 also includes a first rotary cylinder 18, the movable end of which is connected to a first pressure block 12. The first rotary cylinder 18 drives the first pressure block 12, which can both press the tail end plate firmly and not interfere with the placement of battery cells or tail end plates by transfer equipment such as robotic arms.

[0024] In some implementations, please refer to Figure 1 , Figure 5 and Figure 6As shown, the above-mentioned horizontal cell stacking device further includes an end plate clamp 3 and a support plate 4. The end plate clamp 3 and the cell clamp 1 are respectively disposed at opposite ends of the support plate 4. The support plate 4 is provided with a driver 41, which is used to adjust the distance between the end plate clamp 3 and the cell clamp 1. The end plate clamp 3 clamps and positions the first end plate used for assembling the battery module. During the cell stacking process, the driver 41 drives the end plate clamp 3 and the cell clamp 1 to move closer to each other. After moving to the designated position, the cell clamp 1 releases the cell so that the cell falls onto the support plate 4. Then, the cell clamp 1 re-clamps the cell for centering. Then, the cell clamp 1 releases the cell. Finally, the first push plate 11 pushes the cells to stack.

[0025] For details, please refer to Figure 6 As shown, the driver 41 includes a first motor 411 and a lead screw 412. The output shaft of the first motor 411 is connected to the lead screw 412 for transmission. The cell clamp 1 and / or the end plate clamp 3 are threadedly connected to the lead screw 412. The driver 41 drives the lead screw 412 to rotate through the first motor 411, thereby adjusting the distance between the cell clamp 1 and the end plate clamp 3.

[0026] It is worth noting that the driver 41 can drive the cell clamp 1 or the end plate clamp 3 to move independently, or it can drive them to move closer or further apart simultaneously. If the simultaneous driving method is adopted, the lead screw 412 needs to be provided with two threaded sections with opposite directions, and the cell clamp 1 and the end plate clamp 3 are respectively threaded onto these two threaded sections.

[0027] In some implementations, please refer to Figure 5 As shown, the end plate clamp 3 includes a second push plate 31, a second pneumatic gripper 32, a first end plate support block 33, and a second pressure block 34. The second push plate 31 is connected to the cylinder of the second pneumatic gripper 32. The gripping end of the second pneumatic gripper 32 is located in front of the plate face of the second push plate 31. The first end plate support block 33 is located below the gripping end of the second pneumatic gripper 32. The second pressure block 34 can move towards the support surface of the first end plate support block 33. A robotic arm or other transfer device feeds the first end plate into the end plate clamp 3. Its posture can be adjusted using the second push plate 31 and the first end plate support block 33. Then, the second pneumatic gripper 32 clamps the first end plate and achieves centering and positioning on the first end plate support block 33. Next, the second pressure block 34 presses and fixes the first end plate onto the first end plate support block 33. The second pneumatic gripper 32 releases the first end plate so that the gripping end of the transfer equipment such as the robot can smoothly exit the end plate fixture 3. After the gripping end of the transfer equipment such as the robot exits, the second pneumatic gripper 32 re-grips the first end plate, and then the cell stacking operation can be carried out.

[0028] In some implementations, please refer to Figure 5As shown, the end plate clamp 3 also includes a second rotary cylinder 35, the movable end of which is connected to a second pressure block 34. The second rotary cylinder 35 drives the second pressure block 34, which can both press the first end plate firmly and not interfere with the placement of the first end plate by the transfer equipment such as the robot arm.

[0029] Please refer to Figure 7 As shown, this invention discloses a dual-layer processing platform, comprising a base 5, a frame 6, and a battery cell horizontal stacking device. The base 5 has an end plate station and a battery cell station. The frame 6 reciprocates between the end plate station and the battery cell station. The battery cell horizontal stacking device is the same as described above, with the device mounted on both the base 5 and the frame 6. The battery cell horizontal stacking device mounted on the base 5 is capable of reciprocating between the end plate station and the battery cell station. By configuring a base 5 with end plate and battery cell stations, and sliding the frame 6 and the battery cell horizontal stacking device on the base 5, while also mounting the battery cell horizontal stacking device on the frame 6, continuous dual-station operation is achieved.

[0030] Specifically, a robotic arm is configured at the end plate station of base 5 to grip the first and last end plates, and a robotic arm is configured at the cell station to grip the cells. This allows the first end plate to be placed and the last end plate to be assembled when one of the cell horizontal stacking devices is located at the end plate station, while the other cell horizontal stacking device is located at the cell station to stack the cells and the first end plate, thereby achieving continuous operation and further improving production efficiency.

[0031] In some implementations, please refer to Figure 8 As shown, the battery cell horizontal stacking device on the base 5 and the linear reciprocating device 7 on the frame 6 are both used for reciprocating movement between the end plate station and the battery cell station. The linear reciprocating device 7 is used to switch the battery cell horizontal stacking device station on the base 5 and the battery cell horizontal stacking device station on the frame 6.

[0032] For details, please refer to Figure 8 As shown, a second motor 71 is mounted on the frame 6, and a gear 72 is mounted on the output shaft of the second motor 71. A rack 73 that meshes with the gear 72 is mounted on the base 5. The frame 6 moves on the base 5 by rotating the output shaft of the second motor 71 in both directions.

[0033] Similarly, the battery cell horizontal stacking device configured on the base 5 is also equipped with a second motor 71. A gear 72 is provided on the output shaft of the second motor 71, and a rack 73 meshing with the gear 72 is provided on the base 5. The movement of the battery cell horizontal stacking device on the base 5 is realized by the forward and reverse rotation of the output shaft of the second motor 71. Example 1

[0034] Please refer to Figures 1 to 6 As shown, a battery cell horizontal stacking device includes a battery cell clamp 1 and a tail end plate support block 2.

The movable end of the drive cylinder 14 is connected to the tail end plate support block 2. The photoelectric sensor 15 is communicatively connected to the first pneumatic gripper 13 and the drive cylinder 14. The movable end of the push cylinder 16 is connected to the cylinder body of the first pneumatic gripper 13. The pressure sensor 17 is disposed on the movable end of the push cylinder 16. The movable end of the first rotary cylinder 18 is provided with a first pressure block 12. When the tail plate support block 2 is driven by the drive cylinder 14 to the area below the first pneumatic gripper 13, the first rotary cylinder 18 can drive the first pressure block 12 to move toward the support surface of the tail plate support block 2. Example 2

[0035] This embodiment further discloses, based on Embodiment 1, that the horizontal stacking device for battery cells also includes an end plate clamp 3 and a support plate 4.
