Description

Technical Field

[0001] This invention relates to a mechanical limiting tooling for battery fluid replenishment and perforation, belonging to the field of battery repair and secondary utilization. Background Technology

[0002] With the development of the new energy industry, a large number of retired batteries are generated. Direct recycling would inevitably lead to resource waste due to incomplete use. Therefore, the tiered utilization of retired batteries is an important measure to improve the high-value reuse of industrial waste materials.

[0003] Retired batteries, after prolonged calendar and cycle aging, suffer from excessive electrolyte depletion, resulting in a significant electrolyte deficiency. Replenishing the electrolyte in retired batteries effectively injects fresh "blood" into them, repairing them and increasing their capacity—a highly effective repair method. However, during the electrolyte replenishment process, drilling holes can introduce metal debris from the top cover, posing a risk of internal short circuits. Patent document CN114976332A describes a method that involves drilling blind holes in the battery to be repaired, piercing these holes with a steel needle, and then directly replenishing and sealing the electrolyte. This method effectively avoids the risk of metal debris falling into the battery during drilling and causing a short circuit. However, this method, which involves manually piercing the blind holes with a steel needle, also carries the risk of uncontrollable force causing excessive needle displacement, potentially touching the core and leading to a short circuit. The inventors discovered through research that a press can be used to puncture blind holes. After the press is used, there is an inertial buffer. In order to perform liquid replenishment more accurately and safely, a mechanical limiting tool can be designed for battery liquid replenishment puncture, which can effectively avoid the safety risks brought about by liquid replenishment of retired batteries. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a mechanical limiting tool for battery filling and perforation, so as to achieve precise mechanical limiting of the press, reduce the damage to the battery caused by filling and reduce safety risks.

[0005] To address the aforementioned problems, this invention provides a mechanical limiting fixture for battery fluid filling and perforation, comprising a pair of battery fixing plates, with a mechanical limiting plate positioned above the battery fixing plates, the mechanical limiting plate engaging with four limiting adjustment studs; the outer side of each battery fixing plate is connected to a side support plate via a battery fixing stud.

[0006] Preferably, the side support plate and the limiting adjustment stud are fixed to the base plate.

[0007] More preferably, the side support plate is connected and fixed to the base plate by side support plate connecting studs.

[0008] Preferably, the side support plate is provided with nuts on both sides for limiting the studs used to fix the battery.

[0009] Preferably, the limiting adjustment stud is provided with a pair of nuts for limiting the mechanical limiting plate.

[0010] Preferably, the mechanical limiting plate, side support plate, battery fixing plate, and base plate are made of metal plate, plastic plate, or high-strength composite plate.

[0011] In this invention, the mechanical limiting plate is made of a high-strength material, such as a metal plate, a plastic plate, or a high-strength composite plate. The plate itself bears the pressure of the press head. It is connected to the base plate by 2 to 8 studs, and the displacement of the press head is adjustable by nuts on both sides of the plate. The thickness of the mechanical limiting plate is 5mm to 50mm, and the diameter of the through hole in the center of the plate is larger than the diameter of the needle but smaller than the bottom diameter of the press head by 10 to 50mm, so that the needle can pass through the through hole and receive the press head.

[0012] The side support plate is made of high-strength material, such as metal plate, plastic plate, high-strength composite plate, etc. The thickness of the side support plate is 5mm to 50mm. Each side support plate is connected to the base plate by 2 to 10 side support plate connecting studs, which serve to support the battery fixing studs.

[0013] The battery fixing plate is made of a high-strength material, such as a metal plate, a plastic plate, or a high-strength composite plate. The thickness of the battery fixing plate is 5mm to 50mm. The battery fixing plate is connected to the side support plate via side support plate connecting studs. The left and right movement of the battery fixing plate is achieved by the nuts and studs on both sides of the side support plate, thereby achieving the fixing effect on batteries of different sizes.

[0014] The base plate is made of high-strength material, such as metal plate, plastic plate, high-strength composite plate, etc. The thickness of the battery fixing plate is 5mm to 50mm, which provides stable support for the plate and studs connected to it, and at the same time provides a supporting plane for the battery fixing plate and the battery.

[0015] This device can achieve adjustable mechanical limiting of the press and fix the battery cell, reducing safety risks during the liquid injection process.

[0016] The beneficial effects of the mechanical limiting fixture for battery replenishment and perforation provided by this invention are: it achieves adjustable and precise mechanical limitation protection of the press displacement, avoids battery damage caused by excessive press displacement, and reduces safety risks during replenishment.
