Abstract

This invention belongs to the field of lithium battery protection board production technology, specifically a testing device for power lithium battery protection boards. It includes a test platform with a protection board positioning assembly. The positioning assembly comprises four positioning plates, all slidably connected to the test platform. A crossbeam is slidably mounted on one side of the test platform via a lead screw guide rail four. A mounting plate is slidably mounted on one side of the crossbeam via a lead screw guide rail five. A cylinder six is ​​fixedly connected to one side of the mounting plate, and a probe is fixedly connected to the piston end of the cylinder six. This invention utilizes a test marking assembly to mark each detected fault point with ink. This allows operators to visually observe the fault location during subsequent repairs, avoiding inconvenience caused by forgetting the specific location and improving repair efficiency.
