Description

Technical Field

[0001] This utility model relates to a liquid injection device for steel-cased batteries, and particularly to a battery fixture for side liquid injection of steel-cased batteries. Background Technology

[0002] Currently, lithium-ion batteries have advantages such as high specific energy, high cycle life, and long storage time. They are widely used not only in portable electronic devices such as mobile phones, digital cameras, and laptops, but also in large and medium-sized electric equipment such as electric vehicles, electric bicycles, and power tools. Therefore, the quality qualification rate requirements for lithium-ion batteries are becoming increasingly higher.

[0003] The electrolyte filling process is a crucial step in lithium-ion battery production. The accuracy and efficiency of the electrolyte filling directly determine the consistency and production efficiency of the lithium-ion batteries. Battery fixtures used during electrolyte filling are employed to secure the batteries and prevent movement or shaking. Currently, existing battery fixtures generally only provide stability for vertical electrolyte filling. When lateral electrolyte filling is required, the filling needle injects electrolyte from the side of the battery. When the needle comes into contact with the filling port, a lateral force is generated, causing the battery to tilt and shake, making it impossible to secure the battery properly. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a battery fixture for side injection of steel-cased batteries.

[0005] The objective of this utility model is achieved through the following technical solution: a battery fixture for side-filling of steel-cased batteries, comprising a clamping seat, a first clamping plate on one side of the clamping seat and a second clamping plate on the other side, the first clamping plate and the second clamping plate being elastically connected, a battery clamping groove on one side of the clamping seat corresponding to the first clamping plate, the battery being clamped in the first clamping plate and the battery clamping groove, an elongated hole on one side of the clamping seat corresponding to the second clamping plate, and an opening clamping component passing through the width direction of the clamping seat, wherein an external force pushing the opening clamping component can cause the first clamping plate to release the battery or clamp the battery.

[0006] As an improvement to the battery fixture for side-filling of steel-cased batteries according to this utility model, the first clamping plate and the second clamping plate are connected by multiple guide posts, which penetrate through the clamping seat. A first spring is sleeved on the guide rod located between the first clamping plate and the clamping seat. The function of the first spring is that when the cam rotates to the flat position, the first spring pushes the first clamping plate open through its rebound force, thereby achieving clamping open.

[0007] As an improvement of the battery fixture for side-filling of steel-shell batteries of this utility model, the second clamping plate is provided with a cam mounting hole, a cam is horizontally installed in the cam mounting hole, and a cam positioning shaft is passed through the top of the second clamping plate. The cam positioning shaft passes through the cam mounting hole and is connected to the cam.

[0008] As an improvement of the battery fixture for side-filling of steel-cased batteries according to this utility model, the clamping assembly includes two clamping rods that extend laterally through the width direction of the clamping seat. Both ends of the two clamping rods are connected by connecting blocks. A spring rod is provided in the middle of one of the connecting blocks, and a second spring is sleeved on the spring rod. The other end of the spring rod passes through the clamping seat. A push block is provided on the clamping rod corresponding to the position of the elongated hole. The push block extends out of the elongated hole. When the clamping rod is pushed to move, the push block can move along the elongated hole and contact the cam.

[0009] As an improvement to the battery fixture for side-filling of steel-cased batteries of this utility model, when the push block contacts the cam, it can drive the cam to rotate. When the cam rotates to the convex position, the second clamping plate is pushed out and moved. When the second clamping plate moves, it drives the first clamping plate to move and clamp the battery. When the cam rotates to the flat position, it releases the pressure on the second clamping plate, and the first clamping plate opens under the action of the rebound force of the first spring.

[0010] As an improvement of the battery fixture for side-filling of steel-cased batteries according to this utility model, a clamping pad is provided on the clamping side of the first clamping plate, and the clamping pad is in contact with the battery when the first clamping plate clamps the battery.

[0011] The advantages of this invention are as follows: A battery clamping groove is provided on one side of the clamping base. The battery clamping groove and the first clamping plate together clamp the battery, holding most of the battery in place. During side injection, even when the injection needle is pressing against the battery, the battery will not be displaced by the injection needle due to the positioning of the battery clamping groove and the first clamping plate in various directions. This invention provides convenient clamping, stable battery clamping, and a simple structure. Attached Figure Description

External force pushes the opening clamping component 6 to make the first clamping plate 2 release the battery or clamp the battery.

[0020] Preferably, the first clamping plate 2 and the second clamping plate 3 are connected by multiple guide posts 7, which pass through the clamping seat 1. A first spring 8 is sleeved on the guide rod between the first clamping plate 2 and the clamping seat 1. The function of the first spring 8 is that when the cam rotates to the flat position, the first spring 8 pushes the first clamping plate open by the rebound force, thereby realizing the clamping is opened.

[0021] Preferably, the second clamping plate 3 is provided with a cam mounting hole (not shown in the figure), a cam 9 is horizontally mounted in the cam mounting hole, and a cam positioning shaft 10 is passed through the top of the second clamping plate 3.
