Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a lithium battery testing tool. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and a non-aqueous electrolyte solution.

[0003] For example, a fixture for testing lithium batteries disclosed in publication number CN210968537U can cooperate with a rotating drum by setting a tooth plate. When the tooth plate is pushed manually, the rotating drum can be rotated, thereby raising the threaded rod and thus raising the connecting plate. By setting a connecting hole, it can cooperate with the connecting shaft. When the connecting plate rises, the rotating rod moves. By setting a rotating column, it can cooperate with the rotating rod to move the sliding column, thereby adjusting the two contact blocks. By setting a spring, the contact block can contact and fix the lithium battery, thereby enabling the device to clamp lithium batteries of different sizes, thereby solving the problem of replacing the fixture when testing lithium batteries of different sizes. 2. The fixture for testing lithium batteries can cooperate with the rotating drum by setting a tooth ring. When the tooth plate drives the rotating drum to rotate, the contact block can be adjusted so that the lithium battery can be clamped. When the lithium battery is placed in the contact block, the tooth ring is engaged with the rotating drum by manually moving the rod, so that the rotating drum can be fixed. By setting a positioning rod, it can cooperate with the positioning hole to fix the position of the tooth ring, thereby fixing the rotating drum and the contact block, making the clamping of the device more convenient. However, the above patent can only position a single lithium battery, which means that every time a lithium battery is tested, the worker needs to manually remove it from the groove, and then manually place the next lithium battery in the inner cavity of the positioning groove, which not only takes a lot of time for the worker, but also greatly reduces the efficiency and continuity of the test.

[0004] Therefore, there is an urgent need for a lithium battery testing tool to solve the above problems. Utility Model Content
