Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a positioning device for processing lithium battery cells. Background Technology

[0002] Lithium-ion battery cells are the core component of lithium-ion batteries. They are typically thin sheets with specific thicknesses and dimensions to suit the design requirements of different types of lithium-ion batteries. Visually, the cell surface is smooth and flat, with a uniform texture and clear grain structure, which facilitates the efficient transport of ions and electrons within the battery. The cells are often composed of high-purity metallic materials (such as alloys or compounds of lithium, cobalt, nickel, and manganese) combined with conductive materials. This composite structure ensures both good electrochemical performance and excellent conductivity, enabling the battery to efficiently store and release electrical energy during charging and discharging.

[0003] In the lithium battery manufacturing industry, precise positioning of battery cells is one of the key aspects of lithium battery quality and performance. Currently, many lithium battery manufacturers still use manual loading and positioning methods. Operators need to manually place each battery cell onto the positioning fixture and adjust its position to meet processing requirements. This method is not only labor-intensive but also inefficient.

[0004] To address this issue, we propose a positioning device for lithium battery cell processing. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for processing lithium battery cells, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for processing lithium battery cells, comprising a positioning box and a conveying mechanism.

The inner walls of both ends of the positioning boxes are movably connected to threaded rods via openings using rotating shafts. The interior of the positioning boxes is provided with a translation plate. One side outer wall of the translation plate has an internal threaded hole. The inner wall of the internal threaded hole is threadedly connected to the outer wall of the threaded rod. Two push rods are fixedly provided on one side outer wall of the translation plate. One end of each push rod passes through the outer wall of the positioning box and is fixedly provided with a pressing plate.

[0007] Preferably, the inner walls of both ends of the positioning box are fixedly provided with two guide rods parallel to the threaded rod, and the outer walls of both ends of the translation plate are provided with guide holes, and the outer walls of the guide rods and the inner walls of the guide holes are slidably connected.

[0009] Preferably, the first motor is fixed to one end of the outer wall of the positioning box, the output shaft of the first motor is fixedly connected to one end of the outer wall of the first rotating rod through a coupling, the three first rollers are respectively installed on the first rotating rod, the first rollers are respectively installed on one end of the inner wall of the positioning cavity, the three second rollers are respectively installed on the other end of the inner wall of the positioning cavity, the conveyor belt is sleeved on the outer walls of the first rollers and the second rollers, and a first motor fixing cover is fixedly provided on one side of the outer wall of the positioning box, and the first motor is fixed inside the first motor fixing cover.

[0010] Preferably, the inner walls of both sides of the positioning box are movably connected to a second rotating rod via bearings through openings. A second motor is provided on one outer wall of the positioning box. The output end of the second motor is fixedly connected to one end of the outer wall of the second rotating rod. The outer wall of the second rotating rod is fixedly provided with second synchronous pulleys distributed at equal intervals. A first synchronous pulley is fixedly provided on one end of the outer wall of the threaded rod. A second motor fixing cover is fixedly provided on one outer wall of the positioning box.

[0011] Preferably, the top outer wall of the positioning box and the bottom outer wall of the positioning box have positioning openings at corresponding positions, and the second synchronous wheel and the outer wall of the first synchronous wheel are connected by a synchronous belt through the inside of the positioning opening.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The first and second motors are synchronized through a control system. When the conveyor belt transports the battery cells to the positioning cavity, the second motor drives the second rotating rod to rotate, which in turn drives the second synchronous wheel to rotate. The second synchronous wheel drives the first synchronous wheel to rotate via a synchronous belt, which in turn drives the threaded rod to rotate.
