Description

Technical Field

[0001] This utility model relates to a soft-pack lithium battery forming equipment, and in particular to a battery positioning mechanism on a soft-pack lithium battery forming equipment. Background Technology

[0002] Soft-pack lithium batteries are the third generation of power batteries developed from the original steel-cased, aluminum-cased, and plastic-cased batteries. They are widely used in electric bicycles, electric motorcycles, electric cars, power tools, electric toys, solar photovoltaic power generation systems, wind power generation systems, mobile communication base stations, large server backup UPS power supplies, emergency lighting, portable power supplies, and mining safety equipment, among other fields, due to their advantages such as being lighter, thinner, having a longer cycle life, better safety performance, higher energy density, more stable discharge platform, excellent power performance, and being environmentally friendly and pollution-free. In the automated production process of soft-pack lithium batteries, the battery skirts need to be shaped to form the battery.

[0003] Currently, the design of the final shaping mechanism for pouch batteries in existing lithium battery production equipment has certain shortcomings. The shaping of the side skirts of the lithium battery only uses grippers for pulling and positioning. The grippers do not have adaptive pulling force when pulling the battery skirts, and when the clamping or pulling force is too large, clamping marks or wrinkles appear on the battery skirts.

[0004] Therefore, we propose a battery positioning mechanism on a pouch lithium battery forming equipment to solve the problems mentioned above. Summary of the Invention

[0005] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a battery positioning mechanism in a soft-pack lithium battery forming equipment.

[0006] The objective of this utility model is achieved through the following technical solution: a battery positioning mechanism on a soft-pack lithium battery forming equipment, comprising a base plate, a side mounting plate and a front and rear control drive on the base plate, an upper positioning reference mechanism and a lower positioning reference mechanism on the side mounting plate, the front and rear control drive controlling the movement of a base, two mounting seats on the base, the two mounting seats being arranged parallel to each other at intervals, each mounting seat being provided with a linear guide rail and a sensor mounting seat, the sensor mounting seat being provided with a pressure sensor, one end of the pressure sensor being provided with a spring, the linear guide rail being slidably connected to a gripper cylinder mounting seat via a slider, the gripper cylinder mounting seat being provided with a gripper cylinder, the gripper cylinder controlling a gripper to grip the battery skirt, the other end of the spring abutting against the gripper cylinder mounting seat.

[0007] The working principle of this utility model is as follows: the upper servo drive controls the upper positioning reference plate to descend, and the lower servo drive controls the lower positioning reference plate to rise. When the upper and lower positioning reference plates come together, the gripper clamps the battery skirt. The front and rear control drives control the gripper to move. When the battery body touches the upper and lower positioning reference plates, the front and rear control drives stop, the gripper releases the battery skirt, and the upper and lower positioning reference plates reset.

[0008] As an improvement of the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, the upper positioning reference mechanism includes an upper servo drive and an upper positioning reference plate. The output shaft of the upper servo drive is connected to an upper lead screw through a coupling. The upper lead screw is connected to the upper positioning reference plate through an upper lead screw nut. The lower edge of the upper positioning reference plate is provided with two upper notches spaced apart.

[0009] As an improvement of the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, the lower positioning reference mechanism includes a lower servo drive and a lower positioning reference plate. The output shaft of the lower servo drive is connected to the lower lead screw through a coupling. The lower lead screw is connected to the lower positioning reference plate through a lower lead screw nut. The lower edge of the lower positioning reference plate is provided with two lower notches spaced apart.

[0010] As an improvement to the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, the side mounting plate is also provided with a lifting guide rail, and the upper positioning reference plate and the lower positioning reference plate are slidably connected to the lifting guide rail by a slider.

[0011] As an improvement of the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, the upper notch and the lower notch are arranged correspondingly. When the upper positioning reference plate and the lower positioning reference plate are close to each other, the upper notch and the lower notch form a claw extension hole. The two claws controlled by the claw cylinder extend out from the claw extension hole to clamp the battery skirt.

[0012] As an improvement of the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, the front and rear control drive includes a motor mounting base, the motor mounting base is provided with a front and rear control servo motor, the output shaft of the front and rear control servo motor is provided with a transmission screw, and the transmission screw is connected to the base through a screw nut.

[0013] As an improvement to the battery positioning mechanism in the soft-pack lithium battery forming equipment of this utility model, it also includes two gripper pressure regulating valves. One of the gripper pressure regulating valves is connected to a gripper cylinder through a pipe. The gripper pressure regulating valve can adjust the clamping force of the gripper cylinder.

[0014] The beneficial effects of this invention are as follows: The gripper has an adaptive function, and by using a spring and pressure sensor to provide feedback on the positioning pressure (protecting the battery body), it can adaptively position the battery even when it is tilted. The gripper pressure can be adjusted individually, preventing marks from being left on the edge of the battery. Attached Figure Description
