[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3In this embodiment of the present invention, the battery clamping and detection mechanism includes a workbench 1. A movable frame 2 is vertically mounted on the surface of the workbench 1, and the movable frame 2 can move horizontally left and right on the surface of the workbench 1. A second lifting frame 21 is horizontally mounted on the top of the movable frame 2, and the second lifting frame 21 is parallel to the top of the movable frame 2. The second lifting frame 21 moves vertically up and down on the top of the movable frame 2. A plurality of first electrode clamping blocks 23 and a plurality of second electrode clamping blocks 25 are arranged between the second lifting frame 21 and the movable frame 2. The plurality of first electrode clamping blocks 23 are all vertically located at the top of the movable frame 2, and the plurality of second electrode clamping blocks 25... All 25 are vertically located at the bottom surface of the second lifting frame 21. The plurality of second pole lugs 25 and the plurality of first pole lugs 23 are parallel to each other, and the second lifting frame 21 and the plurality of second pole lugs 25 move in the same direction. Thus, when the second lifting frame 21 moves up and down at the top of the moving frame 2, it simultaneously drives the plurality of second pole lugs 25 and the plurality of first pole lugs 23 to press or separate. A first lifting frame 8 is provided between the moving frames 2, and the first lifting frame 8 is vertically located at the middle position on the surface of the worktable 1. The first lifting frame 8 moves up and down on the worktable 1. A lifting frame 8 has a horizontal beam 9 at its top, and a battery placement rack 12 is vertically mounted on the top of the beam 9. Each battery placement rack 12 has a battery 15 to be tested placed on its top. Clamping block moving frames 13 are laterally mounted at both ends of the bottom surface of the battery placement rack 12, and these frames are parallel to each other and horizontally staggered. A first clamping block 14 and a second clamping block 16 are vertically mounted on the top of each clamping block moving frame 13. The first clamping block 14 and the second clamping block 16 are laterally positioned on the battery placement rack 12, and they can move horizontally on the battery placement rack 12 while the battery 15 is positioned... Between the first clamping block 14 and the second clamping block 16, when the battery 15 to be tested is placed on the battery placement rack 12, the clamping block moving frame 13 at the front end of the bottom surface of the battery placement rack 12, together with the second clamping block 16, moves horizontally to the right side of the battery placement rack 12, and the clamping block moving frame 13 at the rear end of the bottom surface of the battery placement rack 12, together with the first clamping block 14, moves horizontally to the left side of the battery placement rack 12, so that the first clamping block 14 and the second clamping block 16 close together and clamp the battery 15 and fix the position of the battery 15, so that the battery 15 will not shift its position during the testing process, and prevents the testing error from being too large;Therefore, when the battery 15 is positioned, the first lifting frame 8 drives the battery placement rack 12 to rise synchronously, and stops rising when the battery placement rack 12 and the battery placement rack 12 are on the same horizontal plane. At this time, the moving frame 2, together with the second lifting frame 21, moves from both sides of the workbench 1 surface toward both sides of the first lifting frame 8, so that the tabs at both ends of the battery 15 are horizontally supported on the first tab clamp 23. The moving frame 2 then stops moving. At this time, the second lifting frame 21 drives the second tab clamp 25 to move downward and press it against the first tab clamp 23, thereby clamping the tabs on both sides of the battery 15. Through the electrical connection between the first tab clamp 23 and the second tab clamp 25, the external testing equipment is connected, so that OCV testing is performed when the second tab clamp 25 and the first tab clamp 23 clamp the tabs on both sides of the battery 15.
