Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery winding, in particular to a dust removal device for a lithium battery winding machine. Background Art

[0002] A lithium battery uses lithium metal or lithium alloy as the negative electrode material, so it is also called a lithium metal battery. Different from other batteries, a lithium battery has characteristics such as high charging density, long life and high unit cost. The battery core used in a lithium battery is one of the most important components of a lithium polymer battery. When producing the battery core, an automatic winding machine is needed for processing. When processing the battery core, a large amount of powder will be generated on the surface of the battery core, and special equipment is required to clean the powder.

[0003] When the existing dust removal device removes dust from the lithium battery electrode plate, it can only remove dust from one side surface of the electrode plate, and the dust removal effect is poor. Moreover, the existing dust removal device is usually fixedly installed on the surface of the winding machine, and it is not convenient to disassemble and assemble for maintenance when a failure occurs.

[0004] Therefore, aiming at the problem that the dust removal device of the above-mentioned lithium battery winding machine cannot remove dust from both side surfaces of the lithium battery electrode plate at the same time and is not convenient for disassembly and maintenance, it is urgently needed to be solved to improve the use scenario of the dust removal device of the lithium battery winding machine. Summary of the Utility Model

[0005] In order to overcome the problem that the dust removal device of a common lithium battery winding machine can only remove dust from one side surface of the lithium battery electrode plate when removing dust from the lithium battery electrode plate, the dust removal effect is poor, which affects subsequent production and processing. Moreover, the existing dust removal device is usually fixedly installed on the surface of the winding machine, and it is not convenient to disassemble and assemble for maintenance when a failure occurs.

[0006] The technical solution of the utility model is as follows: A dust removal device for a lithium battery winding machine includes a base. There are two groups of bases that are symmetrically arranged up and down. Quick-release components are provided on the upper surface of the upper group of bases and the lower surface of the lower group of bases. The quick-release components are connected to the surface of the winding machine. Support seats are provided on the other side surfaces of the upper and lower groups of bases. A connecting seat is installed on the side surface of the support seat away from its corresponding base. A dust suction component is installed on the upper surface of the connecting seat. The dust suction component includes a connecting pipe, a suction head, a suction pipe, a main pipe and a suction pump; A connecting pipe is installed on the upper surface of the connecting seat. A suction head is provided at the top end of the connecting pipe. And a suction pipe is connected to the rear side surface of the connecting pipe. The end of the suction pipe is connected to the main pipe. A suction pump is provided on the right side surface of the main pipe. The bottom surface of the suction pump is connected to a dust conveying pipe. The end of the dust conveying pipe is connected to a collection component.

[0007] Preferably, the quick-release component is provided to facilitate the quick disassembly and assembly of the whole device, which is convenient for the staff to perform maintenance, so as to solve the problem that the existing device is usually fixedly installed and not easy to repair. And by providing the dust suction components symmetrically up and down, the dust removal operation can be carried out on both the upper and lower surfaces of the lithium battery electrode sheet, so as to solve the problem that it is difficult for the existing dust removal device to remove dust on both sides of the lithium battery electrode sheet at the same time.

[0008] As a preference, the quick-release component includes a suction cup and a magnetic strip; suction cups are installed on the side surfaces of the two bases close to the winding machine, and magnetic strips are installed on the side surfaces of the two bases. The upper surface of the suction cup after adsorption is flush with the upper surface of the magnetic strip. By providing the suction cup, during installation, the suction cup can adsorb on the surface of the winding machine shell. After adsorption, the surface of the magnetic strip just fits the winding machine shell, so that it can be magnetically attracted to the winding machine, thus achieving the purpose of facilitating quick disassembly and assembly.

[0009] As a preference, mounting strips are provided on the front side surfaces of the two connecting seats, and bristles are provided on the upper surfaces of the mounting strips. The tips of the two groups of bristles cross each other. The bristles are made of natural animal hair and a conductive coating is applied on the surface. By providing the bristles, the first dust removal can be carried out on both the upper and lower surfaces of the lithium battery electrode sheet, and the conductive coating applied on the surface of the bristles can eliminate the static electricity on the outer surface of the lithium battery electrode sheet, thus preventing the static electricity on the surface of the lithium battery electrode sheet from adsorbing dust again after dust removal, thereby improving the dust removal quality.

[0010] As a preference, the suction heads are arranged in an array on the surface of the connecting pipe, and the adsorption parts of the upper and lower groups of suction heads are mutually attached. Each suction head is connected to the main air pipe through an independent suction pipe. By providing independent suction heads and suction pipes, each group can operate independently. If a suction pipe is blocked, the problem of the dust removal effect decline can be avoided. At the same time, it is convenient for the staff to replace individual components, reducing costs. And the mutually attached suction heads can better fit the surface of the lithium battery electrode sheet, thereby improving the dust removal effect.

[0011] As a preference, symmetric mounting holes are provided on the upper surface of the connecting seat. A spring is fixedly connected to the inner bottom surface of the mounting hole. The top surface of the spring is provided with a sliding seat. The upper surface of the sliding seat is connected to the bottom surface of the connecting pipe, and the sliding seat is slidably connected to the mounting hole. By providing the spring, when the suction head contacts the lithium battery electrode sheet, the spring will be compressed, thereby driving the suction head to move towards the position of the mounting hole. The spring's resilience effect will push the suction head towards the side of the lithium battery electrode sheet again, so that the suction head can always fit the surface of the lithium battery electrode sheet.

[0012] Preferably, the collection assembly includes a protective cover, a collection box, and a flocculant. The end of the dust transport pipe is connected to the protective cover. Inside the protective cover is a collection box, and a flocculant is added to the collection box. The dust transport pipe passes through the rear surface of the protective cover and inserts into the flocculant. By setting the flocculant, when the dust sucked in by the dust transport pipe is input into the flocculant, the flocculant will flocculate the dust into lumps, making it convenient for the staff to clean up.

[0013] Preferably, the collection assembly includes a chute and a slider. Symmetrically arranged chutes are provided on the inner surfaces of the left and right sides of the protective cover, and sliders are processed on the left and right side surfaces of the collection box. The sliders are matched with the chutes, and the collection box is slidably connected to the protective cover through the sliders. By setting the chute and the slider, the collection box can be easily disassembled and assembled, facilitating the staff to quickly position and install and perform daily maintenance and cleaning.

[0015] 1. By setting the quick-disassembly component, the whole device can be quickly disassembled and assembled, facilitating the staff to perform maintenance, so as to solve the problem that the existing device is usually fixedly installed and not easy to repair. And by setting the upper and lower symmetric dust suction components, dust removal operations can be carried out on both the upper and lower surfaces of the lithium battery electrode sheet, so as to solve the problem that it is difficult for the existing dust removal device to perform dust removal on both sides of the lithium battery electrode sheet at the same time;

[0016] 2. By setting the suction cup, during installation, the suction cup can adsorb on the surface of the winding machine's shell. After adsorption, the surface of the magnetic attraction strip just fits the surface of the winding machine's shell, so that it can be magnetically attracted to the winding machine, thus achieving the purpose of easy and quick disassembly and assembly. And by setting the brush bristles, the first dust removal can be carried out on both the upper and lower surfaces of the lithium battery electrode sheet, and the conductive coating applied on the surface of the brush bristles can eliminate the static electricity on the outer surface of the lithium battery electrode sheet, thus avoiding the re-adsorption of dust on the surface of the lithium battery electrode sheet after dust removal, thereby improving the dust removal quality.

[0026] When working, by setting the suction cup 21, during installation, the suction cup 21 can adsorb on the surface of the winding machine's shell. After adsorption, the surface of the magnetic stripe 22 just fits the shell of the winding machine, so that it can be magnetically adsorbed on the winding machine, thus achieving the purpose of facilitating quick disassembly and assembly. And by setting the bristles 6, the upper and lower surfaces of the lithium battery electrode can be dusted for the first time. Moreover, the conductive coating applied on the surface of the bristles 6 can eliminate the static electricity on the outer surface of the lithium battery electrode, thus preventing the static electricity on the surface of the lithium battery electrode from adsorbing dust again after dust removal, thereby improving the dust removal quality. And by setting the mutually independent suction heads 72 and the suction pipes 73, each group can operate independently. If a suction pipe 73 is blocked, the problem of reduced dust removal effect can be avoided. At the same time, it is convenient for the staff to replace individual components, reducing costs. And the mutually fitting suction heads 72 can better fit the surface of the lithium battery electrode, thus improving the dust removal effect. And by setting the spring 11, when the suction head 72 contacts the lithium battery electrode, the spring 11 will be compressed, thus driving the suction head 72 to move towards the position of the mounting hole 10.
