Gravity locking type clamping device and clamping method

Abstract

The invention discloses a gravity locking type clamping device and a clamping method. The gravity locking type clamping device comprises a driving assembly and a clamping assembly, and the multiple clamping assemblies comprise first clamping faces, second clamping faces, first plane four-bar mechanisms and second plane four-bar mechanisms, the first clamping faces are arranged on the first connecting rods, and the second clamping faces are arranged on the second connecting rods. In the plurality of clamping assemblies, each clamping assembly is internally provided with the first plane four-bar mechanism and the second plane four-bar mechanism, so that the first plane four-bar mechanism and the second plane four-bar mechanism can convert the gravity of the lithium battery into auxiliary clamping force when the lithium battery is clamped by each pair of first clamping surface and second clamping surface; the clamping force output by the driving mechanism does not need to be too large, compensation can be conducted through auxiliary clamping force, then self-adaptive clamping can be conducted on different lithium batteries at the same time, the clamping stability is improved, and meanwhile the problem that the clamping force is too large or too small can be solved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a gravity locking clamping device and a clamping method. Background technique [0002] In the prior art, the clamping of the lithium battery mostly adopts an active clamping mechanism, which directly applies a fixed clamping force to the lithium battery to realize the clamping of the lithium battery. This solution only uses the lithium battery in an ideal state, and the actual There will also be differences in size and gravity among multiple lithium batteries in the same batch of products. If a fixed clamping force is used for clamping, it is easy to have problems with too large or too small clamping force. In particular, for the active clamping mechanism that clamps multiple lithium batteries at the same time, there are differences in thickness and gravity between different lithium batteries. The current active clamping mechanism uses the same clamping force f...

[0002] In the prior art, the clamping of the lithium battery mostly adopts an active clamping mechanism, which directly applies a fixed clamping force to the lithium battery to realize the clamping of the lithium battery. This solution only uses the lithium battery in an ideal state, and the actual Multiple lithium batteries in the same batch of products will also have differences in size and gravity. If a fixed clamping force is used for clamping, it is easy to have problems with too large or too small clamping force

In particular, for the active clamping mechanism that clamps multiple lithium batteries at the same time, there are differences in thickness and gravity between different lithium batteries. The current active clamping mechanism uses the same clamping force for each lithium battery, which is easy Some lithium batteries have problems with too large or too small clamping force, which in turn affects the production quality of lithium batteries
