Test apparatus and battery production line

A test apparatus for testing incoming battery cells, characterized by comprising:

• a fixing structure;
• and
• a plurality of test probe structures, wherein the test probe structures are slidably connected to the fixing structure side by side along a first direction,
• wherein the test apparatus further comprises a synchronizer, wherein the synchronizer comprises a synchronization structure that is connected to the test probe structures and a driver that drives the synchronization structure to move relative to the fixing structure, and the synchronization structure drives, during movement relative to the fixing structure, the test probe structures to slide synchronously,
• wherein the synchronization structure is slidably connected to the fixing structure in a second direction, the synchronization structure comprises a plate structure comprising a plurality of guide slots extending in a plane where the first direction and the second direction are located corresponding to the probe structures and each of the test probe structures is provided with a limiting structure slidably connected to the guide slot, the second direction being perpendicular to the first direction, and
• wherein the driver comprises a first fixed portion, a second fixed portion, a screw rod portion with two ends connected to the first fixed portion and the second fixed portion respectively, and a nut portion threadedly connected to the screw rod portion, wherein the first fixed portion and the second fixed portion are spaced apart from each other along the second direction on the fixing structure, and the nut portion is fixedly connected to the synchronization structure.
