Description

Technical Field

[0001] The invention relates to the technical field of energy storage cells, and in particular to a self-locking mechanism of a positioning clamping plate of an energy storage cell. Background Art

[0002] Energy storage cells are a type of equipment used to store and release electrical energy. They are electrochemical devices that can convert electrical energy into chemical energy for storage, and convert chemical energy back into electrical energy for release when needed. During the processing and production of energy storage cells, cells from the same batch need to be combined and packaged to facilitate subsequent classification and transportation, and thus require a positioning mechanism to achieve regularity and clamping positioning.

[0003] The utility model with publication number CN221736067U discloses a battery cell clamping and positioning device, which positions and guides each battery cell through a first horizontal pushing cylinder. The first horizontal pushing cylinder is provided with a square groove, which can well position and guide the battery cell; at the same time, a battery cell slot is also provided under the mounting bracket for further positioning the battery cell, and a blocking cylinder is also provided to block the battery cell components being fed in to ensure that there is only one battery cell component on each workstation, thereby preventing work and material blockage and production line stoppage.

[0004] The utility model with publication number CN218504336U discloses a battery cell positioning module, which drives the second clamping block on the stage through the clamping device to automatically clamp and position the battery cell on the stage, with high positioning accuracy, avoiding manual intervention and jig making during the positioning process of the battery cell, thereby reducing manufacturing costs.

[0005] However, the positioning splint and clamping mechanism for energy storage cells mentioned above still have the following problems during actual use: although the positioning mechanism is used to achieve regular positioning of the cell, such positioning mechanism is only applicable to a single individual cell, and the cells of the same batch cannot be positioned by a cylinder-type positioning mechanism after being combined into an array. At the same time, the specifications of cells of different specifications are quite different after being arranged in an array, so the stability and limiting effect of the cell cannot be guaranteed by clamping alone.

[0006] Therefore, we propose a self-locking mechanism for an energy storage cell positioning splint to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a self-locking mechanism for a positioning clamp for an energy storage battery cell, in order to solve the problem that the existing positioning mechanism is used to achieve regular positioning of the battery cell, but such positioning mechanism is only applicable to a single individual battery cell, and the battery cells of the same batch cannot be positioned by a cylinder-type positioning mechanism after being combined into an array.

[0023] 3. The driving mechanism drives the installation platform and the resistance slide on its right side to approach the battery cell. The battery cell squeezes the resistance slide, driving the traction cable fixedly connected at the left end to stretch, so that the tensioned traction cable drives the fixedly connected self-locking clamping plate to approach the outside of the battery cell, and clamps the outer wall of the battery cell to complete self-locking, preventing the battery cell from shifting and misaligning.

[0024] After the pressure seat is resisted by the battery cell, the pushing bracket and the extrusion slide plate stretch the airbag body. After it expands, it is in a negative pressure state. Air is pumped out of the negative pressure positioning nozzle through a through-connected delivery pipe, and the resistance slide plate and the negative pressure positioning nozzle fit the outer wall of the battery cell to prevent the resistance slide plate and the battery cell from loosening, thereby improving the stability in the self-locking state.
