Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium batteries, in particular to a fixture for preventing the offset of battery cells. Background Art
[0002] When the battery cell is loaded, it will be grabbed by the manipulator gripper and placed on the work station. However, due to the structural characteristics of the manipulator gripper, the manipulator gripper can only grab the air bag part of the battery cell (clamping the air bag part of the battery cell by relying on the first clamping arm and the second clamping arm), so that the battery cell cannot be effectively positioned. As Figure 1 shown, during the movement of the manipulator gripper 11, the battery cell 10 will shake, making it impossible to smoothly and accurately place the battery cell 10 into the work station 12. At the same time, due to the bending of the air bag of some battery cells 10, the battery cell 10 is not perpendicular to the horizontal plane, that is, the battery cell 10 is skewed to one side. When the battery cell 10 is unloaded, it will collide with the clamping groove of the work station 12, resulting in concave points or scratches on the battery cell 10, causing poor appearance of the battery cell 10 and the risk of scrapping the battery cell 10.

[0024] In this embodiment, the manipulator jaw 11 includes a first clamping arm 111 and a second clamping arm 112 which are symmetrically arranged. It should be understood that the manipulator jaw 11 in this embodiment can be implemented by using products in the prior art, and its principle and structure will not be elaborated here one by one.
[0025] The first clamping plate 13 is arranged on the outer side surface of the first clamping arm 111.
[0026] The second clamping plate 14 is arranged on the outer side surface of the second clamping arm 112, and the second clamping plate 14 is symmetrically arranged with the first clamping plate 13.
[0027] In this embodiment, the bottom ends of the first clamping plate 13 and the second clamping plate 14 intersect, that is to say, the core 10 can be clamped by the bottom ends of the first clamping plate 13 and the second clamping plate 14.
[0028] Preferably, the horizontal plane where the bottom ends of the first clamping plate 13 and the second clamping plate 14 are located is lower than the horizontal plane where the bottom ends of the first clamping arm 111 and the second clamping arm 112 are located. It should be understood that the first clamping arm 111 and the second clamping arm 112 are used to clamp the core 10, and the bottom ends of the first clamping plate 13 and the second clamping plate 14 also clamp the core 10. That is, the first clamping arm 111 and the second clamping arm 112 mainly clamp the airbag part of the core 10, while the first clamping plate 13 and the second clamping plate 14 are used to fix the core 10 so that it will not shift from the installation position, thereby playing an auxiliary limiting role to ensure that the core 10 is perpendicular to the horizontal plane, so that the core 10 can vertically enter the clamping groove of the station 12 during material unloading, and avoid the risk of rejection due to the appearance defect of the core 10 caused by the core 10 being skewed and colliding with the station.
[0029] Furthermore, the first clamping plate 13 and the second clamping plate 14 are made of stainless steel material, and the first clamping arm 111 and the second clamping arm 112 are made of silica gel material. It should be understood that the silica gel material is soft and will not cause damage to the battery cell 10.
[0030] Of course, in some embodiments, a silica gel material layer is coated on the outer layers of the first clamping plate 13 and the second clamping plate 14, which also plays a protective role for the battery cell 10.

[0035] Furthermore, the first clamping plate 13 is arranged in the first inclined surface 113 by a threaded connection method, and the second clamping plate 14 is arranged in the second inclined surface 114 by a threaded connection method.
[0036] In this embodiment, the battery cell offset prevention fixture further includes a first auxiliary plate 15 and a second auxiliary plate 16. The first auxiliary plate 15 is in a long strip rectangular shape and is arranged outside the first clamping plate 13. The second auxiliary plate 16 is in a long strip rectangular shape and is arranged outside the second clamping plate 14.
[0037] Furthermore, a first threaded hole is provided in the first inclined surface 113, a second threaded hole is provided in the first clamping plate 13, and a third threaded hole is provided in the first auxiliary plate 15. A first screw 151 is threadedly connected in the third threaded hole, the second threaded hole, and the first threaded hole. It should be understood that in some embodiments, the number of the second threaded holes is multiple, and the multiple second threaded holes are arranged at intervals along the length direction of the first clamping plate 13 at the center of the first clamping plate 13, so that the first screw 151 can be passed through the second threaded holes at different positions as needed to change the length that the first clamping plate 13 extends relative to the first clamping arm 111.
[0038] The second inclined surface 114 is provided with a fourth threaded hole, the second clamping plate 14 is provided with a fifth threaded hole, and the second auxiliary plate 16 is provided with a sixth threaded hole. A second screw 161 is threadedly connected in the sixth threaded hole, the fifth threaded hole, and the third threaded hole. It should be understood that in some embodiments, the number of the fifth threaded holes is multiple, and the multiple fifth threaded holes are arranged at intervals along the length direction of the second clamping plate 14 at the center of the second clamping plate 14, so that the second screw 161 can be passed through the fifth threaded holes at different positions as needed to change the length that the second clamping plate 14 extends relative to the second clamping arm 112.
[0039] Preferably, the first auxiliary plate 15 is arranged in the middle of the first clamping plate 13 along the length direction of the first clamping plate 13, and the second auxiliary plate 16 is arranged in the middle of the second clamping plate 14 along the length direction of the second clamping plate 14.
