Description

Technical Field

[0001] This utility model relates to the technical field of rapid positioning mechanisms, and in particular to a rapid positioning mechanism for the XY axis of soft-pack battery cells used in an automatic loading and unloading mechanism for soft-pack battery cells. Background Technology

[0002] Currently, there are several methods for positioning lithium-ion power battery cells: one method is to use a fixed stop block on one side to hold the cell in place, and a push cylinder on the other side to push the cell into position. The cylinder is in a fixed length manner. The disadvantage is that if some cells are too large, the clamps may cause squeezing when they are placed on the fixed end, resulting in cell damage and other problems, leading to scrap and defects.

[0003] Another method uses XY servo motors to control the cell tray, with six position detection switches (at different positions) placed around it. The XY cell tray moves to detect the position offset and perform precise positioning in several directions.

[0004] In the two scenarios described above, the first positioning method, which involves pushing, can easily cause damage to the battery cell body, or even lead to electrode misalignment, resulting in the battery cell being scrapped or defective. The second method is costly, occupies internal equipment space, and reduces positioning speed and time, thus decreasing production capacity. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems by providing a novel XY-axis rapid positioning mechanism for soft-pack battery cells used in automatic loading and unloading mechanisms. This mechanism achieves accurate edge positioning of soft-pack battery cells through a pusher cylinder assembly with two degrees of freedom on the XY axis. The positioning speed is fast and the efficiency is high. The mechanism is simple, reliable, easy to maintain, and low in cost, and can provide a good foundation for subsequent accurate material handling or soft-pack battery cell testing processes.

[0006] This utility model is achieved through the following technical solution: A rapid XY-axis positioning mechanism for pouch cells is applied to an automatic loading and unloading mechanism for pouch cells. It includes a base support assembly, a pouch cell placement platform, an XY-axis positioning baffle, an X-axis pushing cylinder assembly, and a Y-axis pushing cylinder assembly. The pouch cell placement platform is located at the top of the base support assembly, and pouch cells are placed on the platform. The XY-axis positioning baffle is located on the right side of the platform to prevent pouch cells from falling off. The X-axis pushing cylinder assembly is located at the left end of the platform, and the Y-axis pushing cylinder assembly is located at the rear end. The X-axis or Y-axis pushing cylinder assembly rapidly positions, quickly removes, or tests the pouch cells on the platform.

[0007] As a further step, the base support assembly includes a base plate, support rods, and a top plate. The base plate is mounted on a mounting frame on the automatic loading and unloading mechanism for soft-pack battery cells. Support rods are provided at the four corners of the base plate, and a top plate is provided at the top of the support rods. A Y-axis pushing mounting groove is provided at the rear end of the top plate.

[0008] As a further step, the X-axis pusher cylinder assembly includes an X-axis pusher cylinder, an X-axis pusher connecting block, and an X-axis pusher positioning block. The X-axis pusher cylinder is installed above the left end of the top plate. An X-axis pusher connecting block is provided on the right side of the X-axis pusher cylinder, and an X-axis pusher positioning block is provided on the right side of the X-axis pusher connecting block. The X-axis pusher positioning block positions the soft-pack battery cell on the soft-pack battery cell placement platform for testing and prevents the soft-pack battery cell from becoming loose.

[0009] As a further step, the rear end of the pouch cell placement platform is provided with a limiting groove.

[0010] As a further step, the Y-axis pusher cylinder assembly includes a Y-axis pusher cylinder, a Y-axis pusher guide rail, a Y-axis pusher slider, a Y-axis pusher base plate, and a Y-axis pusher positioning block. The Y-axis pusher cylinder is installed above the rear end of the top plate. The bottom of the Y-axis pusher positioning block is inserted into the Y-axis pusher mounting groove at the rear end of the top plate. The bottom of the rear end of the top plate is provided with a Y-axis pusher guide rail. A Y-axis pusher slider is provided on the Y-axis pusher guide rail. A Y-axis pusher base plate is provided on the Y-axis pusher slider. The bottom of the Y-axis pusher positioning block is connected to the Y-axis pusher base plate, and the upper part of the Y-axis pusher positioning block is connected to the Y-axis pusher cylinder. The Y-axis pusher cylinder drives the Y-axis pusher positioning block to move forward, and the Y-axis pusher positioning block drives the Y-axis pusher slider to move back and forth on the Y-axis pusher guide rail. The Y-axis pusher positioning block is embedded in the limiting groove at the rear end of the soft-pack battery cell placement platform, and positions the soft-pack battery cell on the soft-pack battery cell placement platform for testing, and prevents the soft-pack battery cell from loosening.

[0011] As a further step, the Y-axis pusher base plate is T-shaped.

[0012] The beneficial effects of this utility model are as follows: (1) The mechanism achieves accurate edge positioning of soft-pack battery cells through the push cylinder assembly with two degrees of freedom of XY axis. The positioning speed is fast and the efficiency is high. The mechanism is simple, reliable and easy to maintain, and has low cost. It can provide a good foundation for subsequent accurate material picking or soft-pack battery cell testing processes. (2) The soft-pack battery cells placed on the platform are quickly positioned or quickly picked up or tested by the X-axis pusher cylinder assembly or the Y-axis pusher cylinder assembly. According to the actual production line requirements, it can improve the quick positioning of soft-pack battery cells, improve efficiency, and reduce the scrap caused by soft-pack battery cells. The process steps are fewer and faster, and it effectively avoids defective products caused during the mass production of soft-pack battery cells, thus improving the production efficiency and quality of soft-pack battery cells.
