Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a fixture for electrode group insertion. Background Technology

[0002] Lead-acid batteries are reversible DC power sources, capable of converting chemical energy into electrical energy and vice versa. A lead-acid battery mainly consists of an electrolyte, a casing, and electrode groups. The electrolyte is a sulfuric acid solution. During battery manufacturing, the battery box is welded and processed on a per-electrode basis. Each electrode group consists of several sets of positive and negative plates and separators between them. Generally, the electrode groups are first fixed in a casting and welding fixture, followed by the casting and welding of the busbars. After casting and welding, the electrode groups are pressed into the battery box; this process is called electrode group insertion.

[0003] Chinese patent CN202323184574.2 discloses a battery electrode group insertion clamp, including a mounting plate, a power source, clamping plates, guide posts, and guide sleeves. The power source is mounted on the mounting plate. The guide posts connect two or more clamping plates into a whole. The guide sleeves are sleeved on the guide posts at the position between two clamping plates. Each clamping plate includes a fixed plate and a movable plate. The movable end of the power source is connected to the movable plate and drives the movable plate to move along the guide posts. When the power source pushes the movable plate, the guide sleeve provides a blockage for the movable plate, so that the clamping plates can maintain a fixed distance, thereby ensuring that the thickness of the electrode group is a fixed value after clamping.

[0004] However, the existing slotting fixtures have technical problems such as a lack of rational structural design, inconvenience in longitudinal clamping and limiting of electrode groups, and increased battery production costs. Utility Model Content

The overall structure is compact, rationally laid out, and has good operational stability.
