Description

Technical Field

[0001] The utility model relates to the technical field of new energy battery recycling, in particular to a pole piece feeding mechanism. Background Art

[0002] The prospects of the lithium battery recycling market are very broad. With the popularization of products such as electric vehicles and smart phones, the number of discarded lithium batteries is also increasing. At the same time, the widespread use of renewable energy has also driven the growth of lithium battery demand. These discarded lithium batteries contain valuable rare metals and materials, and recycling has high economic benefits. The government has provided good policy support for the battery recycling industry, including tax incentives and subsidy policies, encouraging companies to engage in battery recycling business and providing necessary financial support and technical support. The formulation and promotion of these policies will further promote the development of the lithium battery recycling market. With the continuous advancement of science and technology, lithium battery recycling and disassembly technology is also constantly improving and innovating. Equipment manufacturers are also constantly improving the automation and intelligence level of equipment, reducing manual operations, reducing disassembly costs, and increasing the reuse rate of materials.

[0003] Lithium battery cells are usually composed of a multi-layer structure, including positive electrode sheets, negative electrode sheets, and separators. During the unwinding process, it is necessary to ensure that each layer of the structure is completely separated without damaging the material. This requires the equipment to have a precise control system and an efficient separation mechanism. The separation accuracy of the equipment may be affected by many factors, such as wear of mechanical parts, improper adjustment of equipment parameters, etc. This may lead to incomplete or excessive separation of the positive electrode sheet, negative electrode sheet and separator, affecting the subsequent lithium battery recycling steps. The equipment has a low degree of automation, and at the same time, operators need to perform manual operations frequently, which will reduce production efficiency and introduce new impurities to contaminate the electrode sheets. It is necessary to take corresponding measures to solve these defects, which can improve the performance and stability of the equipment and provide strong support for the recycling of new energy power batteries.

DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model is further described in detail below in conjunction with the drawings and specific embodiments.

[0020] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back, etc.), they are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0022] Please refer to Figure 1 to Figure 6 The pole piece feeding mechanism of the embodiment of the utility model includes a feeding linear module, a slide cylinder, a pole piece adsorption component, and a deviation correction component.

[0023] The slide cylinder is arranged on the feeding linear module, and the feeding linear module drives the slide cylinder to perform linear reciprocating motion, so as to realize the round trip path of the reverse winding positive electrode sheet feeding to the vacuum belt. The feeding linear module can adopt a linear screw module. The electrode sheet adsorption assembly is arranged on the slide cylinder, and the slide cylinder is used to adjust the vertical position of the electrode sheet adsorption assembly. In specific implementation, it can be fixed on the feeding linear module by the slide seat and the cylinder seat.

[0024] The electrode piece adsorption assembly includes a rotating cylinder and a vacuum suction cup and a suction plate A for adsorbing the electrode piece. The vacuum suction cup and the suction plate A are arranged on the piston rod of the rotating cylinder. The rotating cylinder is used to adjust the adsorption direction of the vacuum suction cup and the suction plate A, so as to facilitate the feeding of the adsorbed reverse-wound positive electrode piece to the vacuum belt. In specific implementation, the vacuum suction cup and the suction plate A can be fixed on the piston rod of the rotating cylinder by an aluminum profile. The adsorption end face of the vacuum suction cup and the adsorption surface of the suction plate A are on the same plane.

[0025] The deviation correction component includes a cutting cylinder, a cutter, a cutter limit block, and a suction plate B for adsorbing the offset pole piece. The cutting cylinder drives the cutter to cut off the offset pole piece. The deviation correction component is located in the direction of movement of the pole piece adsorption component, that is, on the way from the positive pole piece to the vacuum belt. The cutter is a serrated cutter, that is, the blade is serrated. The suction plate B is used for deviation correction and unwinding. When the pole piece is too offset, it can be cut with a cutter. Among them, the cutter is controlled by the cutting cylinder to control the action and the cutter limit block to control the cutting position. The suction plates A and B can adopt a conventional structure, that is, the surfaces of the suction plates A and B are provided with a plurality of adsorption holes, and the suction plates A and B are provided with air ducts inside, and the air ducts are connected to the vacuum pump through air pipes.

[0026] As an implementation mode, the pole piece feeding mechanism further includes a movable bracket with adjustable position, and the feeding linear module is arranged on the movable bracket.

[0027] As an implementation mode, the pole piece feeding mechanism further includes a deviation correction bracket with adjustable position, and the deviation correction component is arranged on the deviation correction bracket.

[0028] As an implementation method, the pole piece feeding mechanism further includes a drag chain slot provided on one side of the feeding linear module. The drag chain slot is used to place the drag chain, which plays a protective and pulling role for the lines and air pipes used by the pole piece feeding mechanism.

[0029] The working principle of the utility model is as follows: after the battery cell is rolled back to expose the positive electrode piece, the feeding linear module transmits the electrode piece adsorption component to the positive electrode piece; the rotating cylinder reverses the vacuum suction cup and the suction plate to adsorb the electrode piece, and the feeding linear module transmits the feeding, and during this process, the correction component corrects the loaded electrode piece; after the feeding linear module transmits the feeding position, the rotating cylinder reverses, and the work is completed when the electrode piece is fed to the vacuum belt; it then flows into other conveyors for subsequent operations.

[0030] The utility model does not require manual rewinding and loading, and the rewinding and unfolding positive electrode plates are fully automatically loaded. Manually loaded plates are prone to uneven fractures, and the plates require cleaning and recycling, which is not suitable for manual work. The utility model adopts an adsorption and transportation method to adsorb the unfolded positive electrode plates, and uses a combination of multiple cylinders and modules to transport the plates flatly to the vacuum belt cleaning table. This adsorption and transportation method can avoid the introduction of impurities and oil stains and the problem of plate fracture. The flat and self-cleaning positive electrode plates are conducive to the subsequent high-purity recovery of lithium iron phosphate.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
