Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automatic equipment, and particularly relates to a battery cell disassembling device. BACKGROUND

[0002] Lithium ion batteries are green and environmentally friendly new energy, and in particular, the blade battery of the roll-up battery cell, because of its thin structure, can realize stable stacking of multiple pieces, and can reasonably occupy the internal space of the electronic product during installation, and therefore, has become the mainstream of current consumer batteries.

[0003] However, the current recycling method for batteries mainly includes disassembly, crushing, and then recycling valuable metals and the like by physical and chemical means. Since the roll-up battery cell is formed by rolling up the electrode, during disassembly, the battery cell needs to be continuously rotated to pull out the electrode completely. In addition, due to the structure of the blade battery, when the battery cell rotates, the following technical problems exist:

[0004] 1. The space diameter reserved for the rotation of the battery cell needs to be greater than the maximum diameter of the battery cell, thereby resulting in a large size of the disassembly device;

[0005] 2. Since the battery cell is of a rectangular structure (i.e., a "blade" structure), the centrifugal force during rotation of the battery cell is concentrated at both ends of the battery cell, thereby making it difficult to accurately control the rotation speed and rotation range of the battery cell;

[0006] 3. During disassembly of the battery cell, the conventional means for supporting the battery cell is mainly through the insertion of a support rod into the center of the battery cell, so that the battery cell can freely rotate on the support rod. Therefore, when the rectangular structure battery cell rotates, the support rod moves at the center position of the battery cell, and at the same time, the support rod cannot firmly clamp and fix the battery cell like a conventional clamp and stably support it. SUMMARY

[0007] The purpose of the present application is to provide a battery cell disassembling device to solve the technical problems described in the background.

[0008] The electric core disassembling device comprises a rack and an external pulling mechanism, the rack is provided with an electric core fixing base, the electric core fixing base is bearing-connected with a rotating disc, the rotating disc is provided with a rotating disc motor, the rotating disc motor is electrically connected with an electric sliding ring installed on the electric core fixing base, the center of the rotating disc is provided with a driving gear in transmission connection with the rotating disc motor, the outer periphery of the driving gear is engaged with at least three driven gears, the center of each driven gear is fixedly connected with a swing rod, the outer end of the swing rod is provided with a supporting finger, when the driving gear drives all the driven gears to rotate in the positive direction, all the supporting fingers are close to the center of the rotating disc for inserting into the center of the electric core, when the driving gear drives all the driven gears to rotate in the reverse direction, all the supporting fingers are opened outward for supporting the electric core to be circular, and the external pulling mechanism is used for pulling out the electric core tab or the electric core diaphragm of the supported electric core.

[0009] According to the technical scheme, the application has the following beneficial effects:

[0010] 1. Before the electric core rotates by itself, the electric core disassembling device drives all the driven gears to rotate in the reverse direction through the driving gear, so that all the supporting fingers are opened outward to support the rectangular electric core to be circular, so that the maximum diameter of the electric core is shortened, that is, the space required by the electric core when rotating by itself is reduced, so that the volume of the disassembling device is reduced.

[0011] 2. Since the rectangular electric core is supported to be circular, the centrifugal force when rotating is concentrated on one circle of the electric core, so that the electric core can stably rotate by itself, and at the same time, the rotation speed and rotation range of the electric core can be accurately controlled.

[0012] 3. Since all the supporting fingers are driven to be opened outward to support the electric core to be circular, the supporting fingers can stably support and fix the electric core without affecting the rotation of the electric core and affecting the pulling out of the electrode from the outer periphery of the electric core, and at the same time, the supporting fingers will not continuously move at the center position of the electric core when supporting the electric core.

Therefore, the present application further realizes the following beneficial effects:

[0016] 1. The battery cell disassembly device can automatically insert the supporting finger into the center of the battery cell according to the thickness of the battery cell;

[0017] 2. It can quickly and accurately clamp the workpiece for machining, detection, assembly and other work.

[0046] Before the battery cell rotates, the battery cell disassembling device drives all driven gears 55 to rotate reversely through the driving of the driving gear 54, so that all support fingers 57 are all outwardly opened to support and round the rectangular battery cell, so that the maximum diameter of the battery cell is shortened, that is, the space required by the battery cell when it rotates is reduced, so that the volume of the disassembling device is reduced. Since the rectangular battery cell is rounded, the centrifugal force when the battery cell rotates is concentrated on one circumference of the battery cell, so that the battery cell can stably rotate, and at the same time, the rotation speed and rotation range of the battery cell can be accurately controlled. In addition, since the battery cell is rounded outwardly by driving all support fingers 57 to be outwardly opened, the support fingers 57 can stably support and fix the battery cell without affecting the rotation of the battery cell and the pulling of the electrode from the outer circumference of the battery cell, and at the same time, the support fingers 57 will not continuously move at the center of the battery cell when supporting the battery cell.

Then, the finger position lifting module 4 drives the finger position lifting seat 41 to lift and adjust the height of the support finger 57, so that the support finger 57 can be moved to the center of the battery cell. Then, the finger position transverse movement module 42 drives the battery cell fixing seats 5 on both sides of the battery cell supporting plate 2 to move close to each other, so as to drive the support finger 57 to be inserted into the center of the battery cell. Therefore, the battery cell disassembling device can automatically insert the support finger 57 into the center of the battery cell according to the thickness of the battery cell. In addition, the workpiece can be quickly and accurately clamped for machining, detection, assembly and other work.
