Lithium battery test automatic adjustment unit and test device with same

Abstract

The invention discloses a lithium battery test automatic adjustment unit and a test device with the same. The lithium battery test automatic adjustment unit includes a main frame and a plurality of formation clamping plates which are arranged in the main frame, are connected in a relative side-to-side movement manner and are used for clamping lithium batteries. Each formation clamping plate includes a heating plate and two PCBs connected to the front and back sides of the heating plate in a relative up-down movement manner. The lithium battery test automatic adjustment unit further includes aPCB up-down adjustment device arranged on the main frame and used for driving the PCBs to move up and down, a push-pull device used for pressing / pulling the formation clamping plates, and a positioning device used for positioning a tool equipped with a lithium battery. As the related devices are integrated on the same main frame, the lithium battery test automatic adjustment unit is independent. Multiple lithium battery test automatic adjustment units can be arranged on a rack in a layered manned without affecting one another. As the PCBs can be adjusted up and down, the formation of lithium batteries at different heights can be tested.

Description

technical field [0001] The invention relates to the field of lithium battery testing equipment, in particular to a lithium battery testing automatic adjustment unit and a testing device provided with the unit. Background technique [0002] The traditional lithium battery test device is generally set up in an assembly line mode. It consists of a loading unit, an unloading unit, and multiple positioning and testing units together to form a large left and right assembly line testing device. The core formation unit includes a frame, A plurality of formation splints arranged in the frame, the formation splints include a heating plate and PCB boards arranged on both sides of the heating plate, during formation, the lithium battery is clamped between the heating plates, thereby realizing heating and pressure, In addition, the electrodes of the lithium battery are connected to the PCB board, so that the electrified formation can be realized while the lithium battery is heated and pr...

AI Technical Summary

Problems solved by technology

However, in the traditional design, the PCB board cannot move up and down relative to the heating plate, so that this large test device can only be used to test lithium batteries of the same height, but not lithium batteries of different heights, so it cannot be used for mixing. production line; in addition, in the traditional design, a lithium battery test device corresponds to a set of upper and lower units, so it is not suitable for large-scale automatic production, because the test of lithium batteries generally takes a long time, most of the time the upper and lower units The material units are all idle, thereby wasting production time; moreover, the large test device occupies a large area, and as long as one of the units fails, the entire test device cannot be used
