[0031] The clamping mechanism 10 can be clamped on a non-bottom surface of the battery cell.

[0032] The clamping mechanism 10 may be a functional structure located above the processing platform in the vertical direction and capable of pre-clamping the battery cell from the non-bottom side of the battery cell. The clamping mechanism 10 includes a transfer fixture 120 and a top cover processing fixture 140. The transfer fixture 120 may be a clamping structure disposed on the processing platform and capable of carrying and clamping the battery cell and transporting the clamped battery cell to the to-be-clamped position of the top cover processing fixture 140 in the horizontal and vertical directions of the processing platform. The top cover processing fixture 140 may be a clamping mechanism 10 disposed above the transfer fixture 120 in the vertical direction and capable of receiving the battery cell transported by the transfer fixture 120 and providing a non-bottom clamping function for the top cover of the battery cell for subsequent welding processing. The transfer fixture 120 includes a battery cell carrier 1220 , a linear motor platform 1240 and a lifting platform 1260 . The linear motor platform 1240 and the lifting platform 1260 can move the battery cell carrier 1220 loaded with battery cells to a preset position.

[0033] like Figure 4 and Figure 5 As shown, the anti-fall mechanism 20 includes a bottom support bearing assembly 220, a bottom support collecting and extending assembly 240 and a support assembly 260.

[0034] The anti-fall mechanism 20 may be a functional structure that is disposed between the transfer fixture 120 and the top cover processing fixture 140, and can be detached from the bottom surface of the battery cell when the battery cell is clamped by the transfer fixture 120, and abuts against the bottom surface of the battery cell when the battery cell is clamped by the top cover processing fixture 140 to lift the battery cell. The bottom support bearing assembly 220 may be a functional assembly that is rotatably connected to the bottom support receiving and stretching assembly 240 at one end, and can be rotated and detached from the bottom surface of the battery cell when the battery cell is clamped by the transfer fixture 120, and can be rotated and abutted against the bottom surface of the battery cell when the battery cell is clamped by the top cover processing fixture 140 to lift the battery cell at the other end.

[0035] The bottom support bearing assembly 220 includes a bearing transmission member 2220, a bottom support contact member 2240 and a bearing seat 2260. The bearing transmission member 2220 is rotatably connected to the bottom support retracting and expanding assembly 240. The bottom support contact member 2240 can be pressed against or separated from the bottom surface of the battery cell.

[0036] The bearing transmission member 2220 may be a transmission structure that is rotatably connected to the bottom support receiving and stretching assembly 240, and is capable of receiving the driving action output by the bottom support receiving and stretching assembly 240 and driving the bottom support contact member 2240 to rotate on the bottom surface of the battery cell under the driving action. The bottom support contact member 2240 may be a supporting structure that can rotate and detach from the bottom surface of the battery cell when the battery cell is clamped by the transfer fixture 120 under the action of the bearing transmission member 2220, and contact the bottom surface of the battery cell when the battery cell is clamped by the top cover processing fixture 140. The bearing seat 2260 may be a mounting seat that can provide an installation space for the bearing transmission member 2220. Optionally, the bottom support contact member 2240 may be a bottom support block.

[0037] The end of the bottom support contact member 2240 close to the bearing transmission member 2220 is provided with a bent contact portion, and the other end of the bottom support contact member 2240 away from the bearing transmission member 2220 is provided with a bottom support rotating portion, and the bent contact portion can rotate with the bottom support rotating portion and abut against or detach from the bottom surface of the battery cell. The support assembly 260 is provided with a hollow ring body, and the bent contact portion can detach from the bottom surface of the battery cell and rotate to the hollow ring body. Optionally, the support assembly 260 can be connected to the bottom support bearing assembly 220 and the bottom support retracting assembly 240, and is provided with a mounting plate of the hollow ring body capable of accommodating the bottom support contact member 2240.

[0038] A transmission through hole is provided at one end of the bottom support contact member 2240 close to the bearing transmission member 2220. The bearing transmission member 2220 includes a rotating shaft, a bearing and a rotating gear. The rotating shaft is passed through the rotating gear and the transmission through hole, and the bearing is sleeved on the rotating shaft. The bearing is installed on the bearing seat 2260. The bearing seat 2260 includes a first bearing seat 2260 and a second bearing seat 2260. The first bearing seat 2260 is provided at one end of the rotating shaft close to the rotating gear, and the second bearing seat 2260 is provided at one end of the rotating shaft close to the bottom support contact member 2240. The first bearing seat 2260 is provided with a first mounting hole, and the second bearing seat 2260 is provided with a second mounting hole. One end of the bearing close to the rotating gear is installed in the first mounting hole, and one end of the bearing close to the bottom support contact member 2240 is installed in the second mounting hole.

[0039] The bottom support collecting assembly 240 includes a collecting transmission member 2420, a collecting driving member 2440 and a connecting member 2460. The collecting transmission member 2420 and the collecting driving member 2440 are connected to the connecting member 2460. The collecting transmission member 2420 is rotatably connected to the load-bearing transmission member 2220. The collecting driving member 2440 can drive the collecting transmission member 2420 and the connecting member 2460 to approach or move away from the load-bearing transmission member 2220.

[0040] The collecting and stretching transmission member 2420 may be a transmission structure that is rotatably connected to the bearing transmission member 2220 in the bottom support bearing assembly 220, and is capable of receiving the driving action output by the collecting and stretching driving member 2440 and transmitting the driving action to the bearing transmission member 2220. The collecting and stretching driving member 2440 may be a driver that is connected to the collecting and stretching transmission member 2420 through a connecting member 2460, and is capable of outputting a driving action and driving the collecting and stretching transmission member 2420 to follow the movement. Optionally, the collecting and stretching transmission member 2420 includes a transmission rack and a sliding guide rail, the transmission rack can be slidably arranged on the sliding guide rail, and the collecting and stretching driving member 2440 can drive the transmission rack to slide relative to the sliding guide rail. The collecting and stretching driving member 2440 may be a driving structure such as a cylinder or a motor. The connecting member 2460 may be a connecting plate.

[0041] When defining the position of the battery cells during the production process, such as Figure 4As shown, under the action of the cylinder, the cylinder rod extends out to push the transmission rack in the retracting and expanding transmission member 2420 to slide relative to the sliding guide rail, thereby driving the rotating gear in the bearing transmission member 2220 to rotate. The rotating gear is installed on the rotating shaft and fixed by a tightening screw. One end of the bottom support block (bottom support contact member 2240) is installed on the rotating shaft in the bearing transmission member 2220. Under the cooperation of the rotating shaft and the bearing, they rotate together and contact the bottom surface of the battery cell to support the battery cell, that is, the anti-drop position, thereby improving the problem that the battery cell may suddenly fall due to air pressure fluctuations, power outages, and gas failures during the clamping and moving process when only relying on the non-bottom clamping method. This can effectively reduce the adverse effects caused by the falling of the power battery, and also reduce the safety hazards to the production of power batteries, while reducing abnormal conditions such as damage to the power battery and mechanism failure.

[0042] like Figure 5 As shown, under the action of the cylinder, the cylinder rod locks back and drives the transmission rack in the retracting and expanding transmission member 2420 to slide relative to the sliding guide rail, and drives the rotating gear in the load-bearing transmission member 2220 to rotate, and the bottom support block will rotate to the hollow ring body in the support assembly 260, that is, the retracted position, to prevent collision with other motion mechanisms, power batteries, etc. At the same time, this rotating battery anti-drop mechanism has a compact structure, saves space and is low in cost, solves the problem of product anti-dropping in narrow spaces and multi-directional avoidance situations, and can improve the yield and stability of battery cell production.

[0043] The battery cell limiting device provided in the present embodiment, when limiting the position of the battery cell in the production process, the clamping mechanism 10 clamps the non-bottom surface (such as the side surface) of the battery cell, and the bottom support bearing assembly 220 and the bottom support collecting and expanding assembly 240 in the anti-fall mechanism 20 are rotatably connected, and the bottom support collecting and expanding assembly 240 can drive the bottom support bearing assembly 220 to be pressed against the bottom surface of the battery cell, thereby realizing simultaneous position limitation of the non-bottom surface and the bottom surface of the battery cell, that is, simultaneous position constraint in the horizontal and vertical directions, and being able to limit the position of the battery cell by relying only on the bottom surface supporting effect provided by the anti-fall mechanism 20 when the non-bottom surface clamping effect disappears, thereby improving the problem of sudden falling of the battery cell due to air pressure fluctuations, power outages, and gas failures during the clamping and movement process when relying only on the non-bottom surface clamping method, while improving the stability of the battery cell position limitation in the production process, thereby meeting higher requirements for battery cell production efficiency.

[0044] The present application also provides a battery cell clamping device, which includes the battery cell limiting device in the above embodiment, and the battery cell limiting device can clamp the battery cell in a preset position.

[0045] When limiting the position of the battery cells in the production process, the battery cells located in the battery cell carrier 1220 are driven by the linear motor platform 1240 to translate to the bottom of the top cover processing fixture 140. During this process, the anti-fall mechanism 20 in the battery cell limiting device is in a retracted state, and there will be no collision when the transfer fixture 120 translates with the battery cells; the lifting platform 1260 lifts the battery cell carrier 1220 in the vertical direction to the clamping position of the top cover processing fixture 140. After the top cover processing fixture 140 positions and clamps the power battery, the anti-fall mechanism 20 in the battery cell limiting device changes to an anti-fall state, and the bottom support block rotates and abuts against the bottom surface of the battery cell to prevent it from falling and being damaged.

[0046] The present application also provides a battery cell clamping device, which includes the battery cell limiting device in the above embodiment.

[0047] The division of the various modules in the above-mentioned battery cell limiting device is only for illustration. In other embodiments, the battery cell limiting device can be divided into different modules as needed to complete all or part of the functions of the above-mentioned battery cell limiting device.
