Description

Technical Field

[0001] The utility model belongs to the technical field of battery processing, and in particular relates to a clamping device for a lithium ion battery. Background Art

[0002] At present, when processing lithium-ion batteries, a clamping device is usually required to clamp and fix the batteries. An existing lithium-ion battery processing clamping tool includes: a clamping tool, a plug-in negative pressure sleeve, an air guide pipe and an air pump device. The clamping tool is provided with plug-in slots at equal intervals. The plug-in negative pressure sleeve is detachably plugged into the plug-in slot. The bottom surface of the plug-in slot is provided with an air guide pipe. The plug-in negative pressure sleeve is detachably connected to the air guide pipe. Although this lithium-ion battery processing clamping tool can use negative pressure to clamp and fix the battery, when placing the battery, due to the formation of negative pressure, the battery is easily sucked in quickly when it is just inserted into the sleeve, thereby causing a collision.

[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a clamping device for a lithium-ion battery includes a base 1, a fixed gas separator 3 and a lifting gas separator 4, connectors 11 are arranged side by side on the front and rear sides of the base 1, cavities are opened side by side inside the base 1, and a clamping seat 2 is slidably arranged in the cavity, and the fixed gas separator 3 and the lifting gas separator 4 both use gas separators with multiple output ends, and the number of the output ends is consistent with the number of the clamping seat 2.

[0016] In this embodiment, combined with the Figure 2 As shown, main air-dividing holes 13 are arranged side by side inside the base 1, and the main air-dividing holes 13 are alternately arranged with the cavity, and one side of each of the main air-dividing holes 13 is provided with air-dividing branch holes 14 side by side, and the air-dividing branch holes 14 are connected with the cavity. Lifting through holes 12 are also arranged side by side on the inner rear side of the base 1, and the lifting through holes 12 are connected with the cavity. At this time, the lower end of the clamping seat 2 blocks the air-dividing branch holes 14.

[0017] In this embodiment, specifically, a battery placement cavity 21 is provided inside the clamping seat 2, L-shaped through holes 22 are provided in sequence in the clamping seat 2, and a rubber ring 23 is sleeved on the outside of the clamping seat 2 to seal the clamping seat 2 and the cavity.
