Description

Technical Field

[0001] This utility model relates to the field of battery liquid injection technology, and more specifically, to a multi-hole liquid injection mechanism for a square battery. Background Technology

[0002] A battery filling mechanism is a device component used to inject electrolyte or other liquids into a battery.

[0003] Traditional single-hole electrolyte filling devices mean that liquid can only be injected into one filling port of the battery at a time, resulting in a relatively slow filling speed. In large-scale production, this significantly extends production time and reduces production efficiency. Due to the slow filling speed, traditional single-hole electrolyte filling devices are unsuitable for situations requiring rapid filling to meet market demands. Single-hole filling may lead to uneven distribution of electrolyte within the battery. After entering from a single filling port, the electrolyte takes a long time to diffuse to all parts of the battery, easily resulting in localized areas of excessively high or low concentration. Uneven filling affects battery performance and lifespan. During single-hole filling, the liquid enters the battery through a small opening, easily introducing air during the filling process, forming bubbles. If these bubbles are not expelled in time, they will occupy internal battery space, affecting the contact between the electrolyte and the plates, and reducing battery performance.

[0004] Therefore, there is an urgent need for a porous liquid injection mechanism for square batteries to improve the shortcomings of existing technologies. Utility Model Content

The injection assembly includes a battery, and an injection stopper is fixedly connected to the upper surface of the battery. The injection stopper communicates with the inner cavity of the battery. Parallel injection holes are provided around the injection stopper on the upper surface of the battery. The parallel injection holes are used to accelerate the liquid injection speed. An injection needle is inserted into the injection stopper during liquid injection. The injection needle is fixedly connected to a fixing assembly. The fixing assembly includes an upper plate, and the injection needle is fixedly connected to the upper plate. A liquid channel is provided inside the upper plate, and the liquid channel communicates with the injection needle. A lifting rod is fixedly connected to the lower surface of the upper plate, and a base plate is fixedly connected to the other end of the lifting rod. A support assembly is fixedly connected to the lower surface of the base plate.

[0007] As a further improvement to this technical solution, the support component includes a frame, a movable door rotatably connected to the frame, ventilation holes on the surface of the movable door, a handle fixedly connected to the surface of the movable door, the handle facilitating opening and closing of the movable door, and casters fixedly connected to the lower surface of the frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This square battery features a multi-hole electrolyte injection mechanism. This mechanism allows for simultaneous injection of electrolyte into the battery through multiple injection holes, significantly reducing injection time. Compared to traditional single-hole injection, it significantly improves production efficiency, meeting the demands of large-scale production. Because multiple injection holes operate simultaneously, the total injection flow rate increases, allowing the electrolyte to fill the battery more quickly. This not only increases production speed but also reduces production line waiting time and improves equipment utilization. Multi-hole injection also ensures a more uniform distribution of electrolyte within the battery. Simultaneous injection from multiple holes at different locations reduces the electrolyte's flow distance within the battery, preventing localized high or low concentrations. Uniform electrolyte distribution contributes to improved battery performance consistency. During charging and discharging, the chemical reactions within the battery are more uniform, reducing performance differences between batteries and improving product quality and reliability.
