Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a formation restraint device for preventing square batteries from overflowing. Background Art

[0002] During the battery production process, some batteries may be squeezed on the large side when they are placed in the restraint tray, causing battery overflow.

[0003] Current situation: The battery is first placed in the restraint tray and then clamped. During the clamping process, the electrolyte may overflow, which will have an adverse effect on the equipment and subsequent production processes.

A restraint plate assembly is arranged directly below the restraint tray assembly to squeeze the large surface side of the square battery. When the square battery is restrained and clamped by the restraint plate assembly, if the electrolyte overflows at this time, it will directly enter the electrolyte pipeline of the existing injection mechanism, and then flow back into the battery by itself after the formation process or after it ends, effectively avoiding the adverse effects of overflow during the restraint process.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] Example 1

[0019] See also Figure 1-2 : A formation restraint device for preventing square batteries from overflowing, comprising a restraint tray assembly 1 and a restraint plate assembly 2, wherein the restraint tray assembly 1 is used to fix and restrain the square battery 3, the injection port of the square battery 3 is connected to the injection nozzle 4 of the injection mechanism, and the restraint plate assembly 2 is located directly below the restraint tray assembly 1 and is used to squeeze the large surface side of the square battery 3.

[0020] In this embodiment, when the square battery is constrained and clamped by the restraint plate assembly, if the electrolyte overflows, it will directly enter the electrolyte pipeline of the existing injection mechanism, and then flow back into the battery after the formation process or after it ends, effectively avoiding the adverse effects of overflow during the restraint process.

[0021] In a specific example, the restraint tray assembly 1 includes a restraint tray 101 , the bottom of which is provided with a limiting groove 1011 for placing the square battery 3 , and the top bolt of the restraint tray 101 is installed with a pressure plate 1012 for hard limiting the top of the square battery 3 .

[0022] It should be noted that in this embodiment, the swollen battery is placed in the limiting groove below the bottom of the restraint tray, and the pressure plate is fixed to the upper end of the restraint tray to hard limit the battery and constrain the battery in the restraint tray; the injection mechanism is pressed down to make the injection nozzle fit the battery injection port.

[0025] In a specific example, the bottom plate of the restraint plate 201 is connected to a cylinder 5 .

[0026] The cylinder of this embodiment provides power for the restraint plate to restrain, and the restraint plate can be driven to move up and down along the restraint channel by the cylinder, thereby automatically restraining and squeezing the bulge on the large side of the square battery.

[0027] In a specific example, the restraint plate 201 includes a bottom plate and at least two vertical plates spaced apart from each other on the bottom plate, and rounded corners are arranged on the tops of the vertical plates.
