Description

Tray positioning mechanism and battery detection equipment Technical Field The invention relates to the technical field of battery testing, in particular to a tray positioning mechanism and battery detection equipment. Background Battery testing is typically accomplished by feeding a tray carrying batteries along a conveyor into a battery testing apparatus, then lifting the tray off the conveyor by a lift bar, and then driving a probe to press-fit the batteries to test the batteries. Wherein, jacking drive cylinder is connected with the base, and jacking drive cylinder drive jacking rod goes up and down. In the prior art, a positioning hole is generally designed at the bottom of the tray, a positioning pin is designed on a battery tray positioning mechanism, the tray is lifted by a large driving cylinder and the battery tray positioning mechanism is inserted into the positioning hole at the bottom of the tray, and then a probe mechanism is driven to move to contact with a pole column of a battery for testing.
