Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to a soft-pack battery clamp. Background Art

[0002] At present, my country's lithium batteries are developing rapidly and are widely used in new energy vehicles and consumer electronics. This puts higher requirements on the safety, charging speed, energy density, etc. of lithium batteries. The battery cells with higher energy density need to be placed in a pressurized fixture during the formation stage. The fixture applies pressure to limit the expansion of the battery cells. The fixture adopts a single-row arrangement and uses a servo motor plus a screw mechanism to pressurize the battery cells. The existing fixture must be pressurized when it is full of material, which will damage the PCB board. For the situation where the fixture is not full of material due to NG in the previous process, it is necessary to make fake batteries with a size similar to the battery and to match the workstations for clamping the fake batteries. The cost of the entire line increases, the efficiency slows down, and the failure rate increases. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model proposes a soft-pack battery clamp. During the actual clamping process, when the clamp is not full, there is no need to place dummy batteries, and the clamping operation can be achieved without causing damage to the clamp.

[0004] To realize the above technical scheme, the utility model provides a soft-pack battery clamp, comprising: a left end plate and a right end plate, a plurality of support columns and a plurality of screw rods are installed between the left end plate and the right end plate, a top plate is sleeved on the plurality of screw rods through a screw rod pair, a servo motor is installed on the right end plate and connected to the screw rod, a plurality of shaft rods are also installed between the left end plate and the right end plate, a plurality of layer plates movable along the shaft rods are installed side by side and at intervals on the shaft rods, the layer plates comprise a silicone pad, a pressure block is installed on the top of the silicone pad, shaft sleeves are provided on both left and right ends of the silicone pad, the shaft sleeves are sleeved on the shaft rod, a guide rail is installed below the shaft sleeve, a wedge block up and down moving assembly is installed on the guide rail, a PCB board is installed on one side of the wedge block up and down moving assembly, and a linkage plate is installed below the wedge block up and down moving assembly.

[0005] In the above scheme, the actual working process is as follows:

[0006] (1) In the initial state, the layers are open, and the wedges move the components up and down to the initial position at the bottom, corresponding to the PCB board being lower than the silicone pad.

[0007] (2) Some layers contain batteries, while others do not. The fixture is not full at this time.

[0008] (3) The servo motor starts to push the top plate to pressurize the layers. Some layers have soft-pack batteries and some do not. The layers are in contact with each other, the pressing blocks are compressed, and the PCB does not extend out to form pressure with the battery ears.

[0009] (4) The linkage plate moves upward, driving the wedge block to move up and down a certain distance. The PCB board extends out of the battery position to form a press fit with the pressure block. The PCB board extends out of the battery position to press the pressure block. The buffer compression spring installed at the joint between the wedge block and the moving plate is compressed.

[0010] (6) In the position without battery, the PCB board is only subjected to the pressure of the buffer compression spring, and there is no pressing force of the servo motor, so the PCB board will not be damaged, thus achieving compatibility with the situation of not full disk.

[0011] Preferably, the wedge block moving up and down assembly comprises a moving plate, a sliding block is installed on the side end of the moving plate, a follower bearing is installed on the sliding block, the follower bearing is embedded and installed on the guide rail, a wedge block is installed on the upper end of the moving plate, a buffer compression spring is installed at the joint between the wedge block and the moving plate, a PCB board is installed above the moving plate, and a linkage plate is installed below the moving plate. In actual operation, the linkage plate can push the moving plate to move up and down along the guide rail through the follower bearing, and then can push the wedge block to move up and down.

[0012] Preferably, a sensor bracket is installed between the bottom side ends of the left end plate and the right end plate, and a plurality of parallel and spaced sensors are installed on the sensor bracket. During actual operation, the moving positions of the top plate and the layer plates can be sensed by the plurality of parallel and spaced sensors installed on the sensor bracket.

[0013] The beneficial effects of a soft-pack battery clamp provided by the utility model are: the soft-pack battery clamp has a simple structure, a reasonable design, and is easy to operate. In the actual clamping process, when the clamp is not full of material, there is no need to place dummy batteries, and the clamping operation can be achieved without causing damage to the clamp, and the clamping efficiency is high.

During actual operation, the linkage plate 6 can push the movable plate 353 to move up and down along the guide rail 33 through the follower bearing 354 , thereby pushing the wedge block 351 to move up and down, and making the movable plate 353 contact with the PCB board 34 .

[0024] In this embodiment, a sensor bracket 9 is installed between the bottom side ends of the left end plate 5 and the right end plate 2, and a plurality of parallel and spaced sensors 10 are installed on the sensor bracket 9. During actual operation, the moving positions of the top plate 8 and the layer plate 3 can be sensed by the plurality of parallel and spaced sensors 10 installed on the sensor bracket 9.

[0025] In this embodiment, the actual working process is as follows:

[0026] (1) Initial state: the layer plate 3 is open, and the moving plate 353 in the wedge block up and down moving assembly 35 is at the initial position at the bottom, corresponding to the PCB board 34 being lower than the silicone pad 31.

[0027] (2) Some layers 3 are filled with batteries, while others are empty. In this case, the fixture is not full.

[0030] (6) In the position without the battery, the PCB board 34 is only subjected to the pressure of the buffer compression spring 352. There is no force from the servo motor 1 to push the layer board 3 to press together, so the PCB board 34 will not be damaged, thereby achieving compatibility with the situation of not being full.
