Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a battery cell clamp. Background Technology
[0002] In automated production lines for cylindrical battery cells, magnetic drive wires are commonly used in conjunction with cell clamps to drive the cells, enabling rapid transfer between different workstations. The transport trajectory of the magnetic drive wire is fixed. At certain workstations, such as the current collector welding station, because the cell needs to be in contact with the current collector, it is conventionally necessary to unlock the cell clamp, release the cell, and then use an auxiliary mechanism to drive the cell away from the clamp and move towards the current collector. Furthermore, maintaining the cell's spatial position must be stable during welding, and after welding, the cell must be reassembled back into the clamp. This makes the automated production line complex, costly, and also increases the failure rate. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0025] Please refer to Figures 1 to 5 A battery cell clamp includes a mounting base plate 121, on which a movable clamp plate 122 is slidably mounted. The sliding direction of the movable clamp plate 122 relative to the mounting base plate 121 is parallel to the axial direction of the battery cell body 11 on the battery cell clamp. Two gripper fixing seats 123 are provided on the upper side of the movable clamp plate 122. The two gripper fixing seats 123 are arranged opposite to each other and are slidably connected to the movable clamp plate 122 through a slide rail slider assembly. The two gripper fixing seats 123 can move closer or further apart. The movement direction of the gripper fixing seats 123 is perpendicular to the sliding direction of the movable clamp plate 122 relative to the mounting base plate 121. A claw body 124 is mounted on the gripper fixing seat 123. In use, the battery cell body 11 is positioned above the moving clamp plate 122 and locked by two claws 124. The moving clamp plate 122 can slide relative to the mounting base plate 121, thereby changing the spatial position of the battery cell in the axial direction of the battery cell body 11 by the movement of the moving clamp plate 122 while the locking state of the claws 124 on the battery cell body 11 remains unchanged. Compared with traditional clamps, this battery cell clamp can better adapt to automated production lines, which helps to reduce the complexity of the production line structure and the failure rate.
[0026] Furthermore, two baffles 1211 are arranged on the upper side of the mounting base plate 121, and the moving clamp plate 122 is located between the two baffles 1211. A first reset member 1213 is provided between the moving clamp plate 122 and one of the baffles 1211. The first reset member 1213 acts on the moving clamp plate 122 to put the battery cell clamp in a transport state. Optionally, in some embodiments, the moving clamp plate 122 is slidably connected to the mounting base plate 121 via a slide rail slider assembly. In this embodiment, in order to reduce the longitudinal dimension of the battery cell clamp, a sliding shaft 1212 is provided between the two baffles 1211. The sliding shaft 1212 passes through the moving clamp plate 122, and the moving clamp plate 122 is slidably connected to the sliding shaft 1212. Optionally, the first reset member 1213 is a spring. In use, the moving clamp plate 122 is slid relative to the mounting base plate 121 by an external force. At this time, the first reset member 1213 is compressed (the first reset member 1213 is installed between the moving clamp plate 122 and the baffle 1211 near the collector plate). After the operation (e.g., collector plate welding) is completed, the external force acting on the moving clamp plate 122 is removed, and the first reset member 1213 acts on the moving clamp plate 122 to reset it, thereby restoring the battery cell clamp to the transport state so that it can be driven by the magnetic drive wire to continue moving to the next station. In another embodiment, the first reset member 1213 can also be a cylinder or electric cylinder provided on the baffle 1211 to drive the moving clamp plate 122 to move, so that the battery cell clamp can switch between the working state and the transport state.
[0027] like Figure 3 As shown, a cell holder plate 125 is provided on the mover clamp plate 122, and a support groove 1251 for accommodating the cell body 11 is provided on the cell holder plate 125. Preferably, there are two cell holder plates 125, and the gripper fixing seat 123 is located between the two cell holder plates 125. The support groove 1251 is an arc groove to accommodate cylindrical cells.
[0028] like Figure 3 As shown, a cam groove plate 126 is slidably mounted on the moving clamp plate 122. The movement direction of the cam groove plate 126 is perpendicular to the movement direction of the gripper fixing seat 123. A roller 1231 is disposed on the gripper fixing seat 123. A drive groove 1261 adapted to the roller 1231 is opened on the cam groove plate 126. The roller 1231 is mounted in the drive groove 1261. The cam groove plate 126 moves relative to the moving clamp plate 122 to drive the gripper fixing seat 123 to move, so that the battery cell clamp switches between a locked state and an unlocked state. In this embodiment, the cam groove plate 126 is slidably connected to the moving clamp plate 122 through a slide rail slider assembly. By driving the cam groove plate 126, the roller 1231 acts on the gripper fixing seat 123 through the drive groove 1261 to move. That is, the battery cell clamp can switch between a locked state and an unlocked state by applying external force to the cam groove plate 126.
[0029] In some embodiments, a second reset member 1232 is disposed between the cell holder plate 125 and the cam groove plate 126. The second reset member 1232 acts on the cam groove plate 126 to make the cell clamp tend to maintain a locked state. Specifically, as Figure 3 As shown, optionally, the second reset member 1232 is a spring. In use, the cam groove plate 126 is driven to move to compress the second reset member 1232 so that the battery cell clamp is in the unlocked state. After the external force acting on the cam groove plate 126 is removed, the second reset member 1232 acts on the cam groove plate 126 to reset it, and the battery cell clamp switches to the locked state to realize the self-locking of the battery cell clamp.
[0030] like Figure 5 As shown, the gripper fixing base 123 includes a main board 1233, receiving blocks 1234, and an extension plate 1235. The main board 1233 is slidably mounted on the moving clamp plate 122. Two receiving blocks 1234 are spaced apart on the main board 1233. The gripper body 124 is provided with an assembly protrusion 1241 extending between the two receiving blocks 1234. The extension plate 1235 is disposed on the main board 1233, and a roller 1231 is mounted on the extension plate 1235. Longitudinally, the lower side of the extension plate 1235 is higher than the lower side of the main board 1233. In this embodiment, the structural design of the assembly protrusion 1241 facilitates rapid positioning and assembly of the gripper body 124 and the gripper fixing base 123, and improves the structural stability of the assembly between the gripper body 124 and the gripper fixing base 123. The extension plate 1235 is used to assemble the roller 1231. Its lower side is higher than the lower side of the main plate 1233 to avoid interference with the cam groove plate 126.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
