Description

Technical Field

[0001] This utility model relates to the field of lithium battery production equipment technology, specifically to a cell conveying mechanism for a lithium battery packaging production line. Background Technology

[0002] Lithium-ion battery cells are the core component of lithium-ion batteries, determining their main performance. Based on materials, they can be classified into lithium cobalt oxide batteries, lithium iron phosphate batteries, and ternary lithium batteries. Lithium cobalt oxide batteries have high energy density but relatively poor safety and are commonly used in small electronic products such as mobile phones. Lithium iron phosphate batteries have high safety and long cycle life but lower energy density and are commonly used in electric vehicles and energy storage. Ternary lithium batteries have good overall performance and high energy density and are widely used in electric vehicles.

[0003] In existing lithium battery cell transport processes, clamps are typically used to hold the cells to ensure stable transport. However, for cells of different sizes and shapes, manual adjustment of the clamps is required, which cannot be adaptively adjusted, resulting in low transport efficiency. In addition, the clamping and transporting equipment gets contaminated with a lot of dust during transport, which easily accumulates on the positive and negative electrodes, reducing the insulation performance between the electrodes. To address this, we propose a cell transport mechanism for a lithium battery packaging production line. Utility Model Content

[0004] The purpose of this utility model is to provide a cell conveying mechanism for a lithium battery packaging production line, in order to solve the problem mentioned in the background art that existing lithium battery cells are usually clamped by clamps to maintain stable conveying during the process. However, for cells of different sizes and shapes, manual adjustment of the clamps is required, and adaptive adjustment of the clamps is not possible, resulting in low conveying efficiency. At the same time, during the conveying process, the clamping and conveying equipment will get contaminated with a lot of dust, which will easily accumulate on the positive and negative electrodes, reducing the insulation performance between the electrodes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cell conveying mechanism for a lithium battery packaging production line, comprising a support plate, a sprocket, a conveying plate, and a clamping plate. The sprocket is rotatably connected to the inner wall of the support plate. The conveying plate is located inside the support plate, and the clamping plate is located inside the conveying plate. A chain is engaged between the teeth of the sprocket. A placement plate is provided in the inner cavity of the conveying plate. A first rack is fixedly connected to the rear side wall of the placement plate. A rotating shaft is rotatably connected to the middle of the upper rear side of the inner side wall of the conveying plate. A face gear is sleeved on the outer side wall of the rotating shaft. A sliding groove is opened on the rear side of the inner side wall of the conveying plate. A slider is slidably connected to the inner cavity of the sliding groove. A connecting member is fixedly connected to the front end of the slider. A clamping plate is fixedly connected to the outer end of the connecting member. A second rack is fixedly connected to the end of the connecting member on the left side, and a third rack is fixedly connected to the end of the connecting member on the right side.

[0006] As a further description of the above technical solution:

[0007] Support columns are fixedly connected to the bottom two sides of the support plate, and a connecting plate is fixedly connected between the lower inner walls of the support columns. A fan is inserted into the top of the connecting plate, and an air outlet hood is inserted into the output port of the fan.

[0008] As a further description of the above technical solution:

[0009] A DC motor is fixedly connected to the left side of the front side wall of the support plate, and a belt is sleeved between the output end of the DC motor and the connection end of the sprocket on the left side.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the chain is welded with mounting parts, and the conveyor plate is fixedly connected between the top ends of the mounting parts.

[0012] As a further description of the above technical solution:

[0013] Limiting cylinders are fixedly connected to the bottom left and right sides of the inner cavity of the conveying plate. A connecting rod is slidably connected to the inner cavity of the limiting cylinder, and the top end of the connecting rod is fixedly connected to the bottom left and right sides of the placement plate. A spring is sleeved on the outer wall of the connecting rod.

[0014] As a further description of the above technical solution:

[0015] The clamping plate is L-shaped and made of rubber. The second rack and the third rack both mesh with the face gear.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The cell conveying mechanism of this lithium battery packaging production line consists of mounting components on a chain, with a conveying plate fixed between the mounting components. A placement plate and a first rack engage with a face gear on the conveying plate. When a cell is placed on the placement plate, gravity compresses a spring, causing the first rack to move downwards and the face gear to rotate counterclockwise. A second and third rack engage with the face gear, and as the face gear rotates counterclockwise, the second and third racks move inwards, causing the clamping plate connected to them to move inwards synchronously and clamp the cell. This mechanism can adaptively clamp cells of different sizes and models without manual adjustment, resulting in high conveying efficiency.

[0018] 2. The cell conveying mechanism of this lithium battery packaging production line effectively reduces dust accumulation on the positive and negative electrodes of the cells by setting a fan and an air hood on the connecting plate to blow dust off the cells before they are conveyed by the conveying plate, thus ensuring the quality of the cells.

By setting a second rack 430 and a third rack 440 to mesh with the face gear 370 respectively, when the face gear 370 rotates counterclockwise, the second rack 430 and the third rack 440 move inward, causing the clamping plate 400 connected to it to move inward synchronously and fit and clamp the battery cell body.
