Embodiment Construction

[0021] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0022] First, a brief description of the power cell testing and sorting device involved in the present invention is given. like Figures 1 to 3 As shown, the testing and sorting method for power cells in this embodiment includes a testing mechanism 1 , a sorting mechanism 3 and a conversion mechanism 2 , and the conversion mechanism 2 is arranged between the testing mechanism 1 and the sorting mechanism 3 .

[0023] The test mechanism 1 includes a test disk 12 arranged vertically. A plurality of cell slots 121 for horizontally accommodating the power cells 4 are evenly distributed on the outer peripheral wall of the test disk 12. The test disk 12 is controlled to rotate by a sorting motor. , a blanking channel 11 is vertically arranged on the upper part of the test disk 12, the blanking channel 11 can only allow a single lateral passage of t...

Abstract

The invention discloses a power battery testing and sorting method. The power battery testing and sorting method includes the steps of putting a power battery into a discharge passage, intermittentlyrotating a test disc, and dropping the power battery into a battery slot in the test disc; after the power battery enters the battery test slot, performing a related electrical performance parameter test on the power battery by an electrical performance test component; dropping the tested power battery into a strip-shaped slot in a conversion disc, blowing air by an air blowing pump when the powerbattery rotates along with the conversion disc by 90 degrees, allowing the power battery to enter a loading tank of a sliding block, and moving the sliding block to move the power battery in the loading tank onto a conversion channel; allowing the power battery to enter a sorting hopper of a sorting mechanism, rotating a sorting disc to enable the power battery to rotate along the side wall of the sorting hopper, and allowing the power battery to enter a corresponding sorting channel. The power battery testing and sorting method has the advantages that automatic sorting of lithium batteries is realized, and the sorting efficiency is improved.

Description

technical field [0001] The invention relates to the field of power cells, in particular to a method for testing and sorting power cells. Background technique [0002] The power battery is the power source that provides the power source for the tool, and its interior is composed of multiple power cells in series or in parallel. The common power cells are lithium cells. Lithium cells are the main practical cells in China. They are widely used in notebook computers, mobile power supplies, electric tools, electric bicycles, electric motorcycles, electric vehicles, solar energy storage power, and wind energy storage. Power supply, base station energy storage power supply and other fields. Lithium batteries must undergo strict voltage and internal resistance tests before leaving the factory and then be classified and graded according to battery performance. [0003] At present, the domestic cell sorting mainly adopts the internal resistance tester, and the manual testing and sor...
