Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, specifically to a battery cell single / double row conversion mechanism. Background Technology

[0002] In the lithium-ion battery production process, the layout design of the cell processing line directly affects production efficiency and workshop space utilization. Traditional cell feeding methods mostly adopt a single-row arrangement, that is, the cells are arranged sequentially along the length of the conveyor tray.

[0003] Taking a battery cell with dimensions of 205mm in length and 175mm in width as an example, if the distance between adjacent battery cells is 260mm, and a single tray in a single-row layout needs to accommodate at least 10 workstations, its total length needs to reach more than 1000mm.

[0004] When the production line contains 10 such stations, the total line length will exceed 10 meters. This design exposes significant problems in space-constrained small and medium-sized workshops: the equipment occupies too much space, leading to difficulties in workshop layout, narrow logistics channels, and even failing to meet basic installation requirements, severely restricting the adaptability and flexibility of the production line.

[0011] When the battery cells are fed in, the battery cell slots of battery cell holder one and battery cell holder two are on the same straight line.

[0012] As an improvement, the cross-section of the battery cell holder is C-shaped, with the battery cell slots connected at both ends of its top, and the positioning mechanism includes a positioning cylinder located near the side of the battery cell slot.

[0013] As an improvement, when the battery cells are fed in, the battery cell slots on battery cell holder one and battery cell holder two are staggered.

[0014] As an improvement, the guide rail assembly includes a guide rail frame and a servo motor connected to one end of the guide rail frame;

[0015] The rotating end of the servo motor is connected to a lead screw that is rotatably mounted inside the guide rail frame;

[0016] The lower end of the battery cell holder is threadedly connected to the lead screw, and the lower wall of the battery cell holder is also provided with a guide plate that protrudes downward and abuts against the outer wall of the guide rail frame.

[0017] As an improvement, the second guide rail assembly has the same structure as the first guide rail assembly and is arranged along the Y-axis direction;

[0018] The lower end of the second battery cell holder is threadedly connected to the inner lead screw of the second guide rail assembly. The lower wall of the second battery cell holder is also provided with a guide plate that protrudes downward and abuts against the outer wall of the inner guide rail frame of the second guide rail assembly.

[0019] (III) Beneficial Effects

[0020] The advantages of this utility model compared with the prior art are as follows: In this application, the single-row feeding of battery cells is converted into double-row output, and the size of the battery cell tray is reduced from the minimum length of 1000mm for a single row to 500mm, which meets the installation conditions of small and short workshops.
