Description

Technical Field

[0001] The utility model belongs to the technical field of battery formation equipment, in particular to a battery formation laminate. Background Art

[0002] Lithium batteries need to go through a formation (aging) process in the production process. In the formation process, the positive and negative tabs of the battery are connected to the power supply of the formation, and the battery is energized for formation. For soft-pack batteries, the electrodes of the battery are set in the form of tabs and are set on the side of the battery. Depending on the size and thickness of the battery, the position of the tabs in the thickness direction of the battery is also different. In order to save costs, current formation equipment needs to be compatible with the formation of batteries of different models. Therefore, when replacing different models of batteries, it is necessary to adjust the position of the battery tab connection plate.

[0003] A battery formation laminate structure and a battery formation fixture are disclosed in the Chinese patent document with publication number CN217822954U, and specifically discloses that the battery formation fixture includes multiple battery formation laminates and a lifting mechanism, and the bottom end of the adjusting member is also extended with a mounting portion for connecting the lifting mechanism, and the lifting mechanism drives the adjusting member to slide up and down. A battery formation laminate structure includes a layer plate, a clamping member and a power connection plate, the layer plate has a clamping surface for clamping the battery, and the clamping member and the power connection plate are arranged on both sides of the layer plate relative to each other; it also includes an adjusting member for adjusting the position of the power connection plate; the clamping surface of the layer plate is also provided with a mounting groove, and the side wall of the mounting groove is provided with an oblique push block, and the oblique push block is provided with an oblique push surface; an adjusting connection portion extends from the adjusting member, and the adjusting connection portion extends into the mounting groove, and is slidably buckled with the oblique push block and is in contact with the oblique push surface; the power connection plate is connected to the adjusting member; the adjusting member is pushed to change the distance between the power connection plate and the clamping surface. By pushing the adjusting member, the adjusting connection part in the adjusting member and the oblique push block are relatively displaced, and then the oblique push block pushes the adjusting member outward or pulls it inward, thereby adjusting the spacing between the power connection plate and the layer plate, so as to meet the requirements of battery connection formation of different thicknesses and avoid the problem of battery tabs being compressed and deformed. In the process of adjustment, the adjusting member is pushed or pulled by the lifting rod to slide up and down.

[0004] In the technical solution disclosed in the above patent document, each layer plate is arranged on the lifting rod, so the lifting rod will be deformed by force, and the deformation in the middle position will increase. The deformation of the lifting rod will directly cause the lifting rod to pull the power board to be misplaced, so the positions of the power boards on each group of layer plates relative to the layer plates will be different. When the battery is set in the formation fixture for formation, the position of the pole ear and the power board will be offset, resulting in poor power connection, and even causing the positive and negative pole ears of the battery on the same side to overlap the same power board and cause a short circuit. Utility Model Content

[0030] In one embodiment of the formation fixture of the present invention, please refer to Figure 1, the formation fixture includes a battery formation laminate 100, a framework 200, a drive shaft 300 and a clamping mechanism 400. Wherein, the framework 200 is provided with a guide post 201, and multiple groups of battery formation laminates 100 are slidably connected to the guide post 201. The clamping mechanism 400 is arranged on a side of the framework 200, and is connected to the battery formation laminate 100, and is used to promote the battery formation laminate 100 to translate along the guide post 201, so that the battery formation laminate 100 can clamp and release the formed battery. And in order to realize that each battery formation laminate can be opened at the same time, a flexible piece is connected between two adjacent battery formation laminates 100. When the battery formation laminate 100 moves to release the battery, the flexible piece can be straightened, so the next battery formation laminate 100 can be pulled by the flexible piece to move simultaneously.

[0031] Please refer to Figures 2 to 5The battery formation laminate 100 includes a layer plate 110, a voltage connection plate 120, an adjustment seat 130, an adjustment screw 140 and a nut seat 150. A mounting surface 131 is provided on one side of the adjustment seat 130, and the voltage connection plate 120 is arranged on the mounting surface 131. The specific connection method can be a screw locking connection. The adjustment seat 130 has two side surfaces, and both sides of the adjustment seat 130 are provided with a plurality of guide grooves 132, and the guide grooves 132 are inclined to the mounting surface 131. Specifically, the angle between the two is between 45° and 60°. The most preferred angle between the two is 50°. The layer plate 110 is provided with a slide groove 111, and the adjustment seat 130 is extended into the slide groove 111, and the two side walls of the slide groove 111 are provided with support pins 112 extending into the guide groove 132, and the support pins 112 are slidably connected with the guide groove 132, so that the support pins 112 support the adjustment seat 130. The layer plate 110 is also provided with a mounting groove 113, the adjusting screw 140 is rotatably connected in the mounting groove 113, and the nut seat 150 is sleeved on the adjusting screw 140 and slidably limited in the mounting groove 113. A guide portion 133 extends from one end of the adjusting seat 130, the guide portion 133 is slidably connected with the nut seat 150, and the sliding direction of the guide portion 131 is perpendicular to the sliding direction of the nut seat 150 in the mounting groove 113. In this embodiment, when it is necessary to adjust the distance between the voltage connection plate 120 and the layer plate 110, the position of the nut seat 150 is adjusted by adjusting the screw 140, and the nut seat 150 drives the adjusting seat 130 to move up or down. When the adjusting seat 130 moves up or down, the adjusting seat 130 moves along the thickness direction of the layer plate 110 under the cooperation of the support pin 112 and the guide groove 132. Specifically, when the adjustment seat 130 is pulled down, the support pin 112 contacts the upper surface of the guide groove 132. Since the guide groove 132 is an inclined surface, the adjustment seat 130 will extend to the outside of the slide groove 111, and vice versa, it will move to the inside of the slide groove 111. In this way, the distance between the voltage connection plate 120 and the layer plate 110 can be adjusted. Since the adjustment screw 140 is used to adjust the voltage connection plate 120 in the thickness direction, the voltage connection plate 120 will not be misplaced due to the deformation of the driving member that drives the adjustment screw 140 to rotate. Ensure that the position of the voltage connection plate 120 will not be misplaced after the adjustment. Ensure the stability of the battery tab connection.

[0032] Further, an embodiment of driving all battery formation laminates 100 to connect the voltage plate 120 through the driving shaft 300, specifically, please refer to Figures 2 to 5The lower end of the layer plate 110 is also provided with a connection hole 114 and a clearance hole 115, and the clearance hole 115 is vertically arranged with the connection hole 114.

The lower end of the adjusting screw 140 is provided with a bevel gear 170 meshing with the disc gear 160; the driving shaft 300 passes through each disc gear 160 and is rotatably connected with the frame 200. In this embodiment, by rotating the drive shaft 300, the drive shaft 300 drives the disc gear 160 to rotate, and under the action of the engagement between the disc gear 160 and the bevel gear 170, the adjusting screw 140 rotates, and then the nut seat 150 can be driven to move up or down, thereby adjusting the position of the voltage connection plate 120. Therefore, the position of the voltage connection plate 120 on all the layers 110 can be adjusted, and the adjustment efficiency is improved. In addition, during the adjustment process, the bending deformation of the drive shaft 300 will not affect the misalignment of the adjustment seat 130, ensuring that the battery can be normally charged.

[0033] Furthermore, in order to enable the driving shaft 300 to drive each disc gear 160 more stably, the disc gear 160 is provided with a square hole 161 , and the driving shaft 300 is a square shaft that matches the square hole 161 .
