Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery manufacturing, and in particular to a lithium battery pole piece cutting machine and a use method thereof. Background Art

[0002] As an important component of new energy, every link in the production process of lithium batteries has an impact on the final performance of the battery. The cutting of lithium battery pole pieces is a key step in the production process. The cutting quality of the pole pieces directly affects the overall performance and service life of the battery. Therefore, lithium battery pole piece cutting machines play a vital role in the production line. Their main function is to efficiently and accurately cut the positive and negative pole piece materials of lithium batteries to ensure the size accuracy and edge uniformity of the pole pieces.

[0003] Existing lithium battery pole piece cutting machines are usually operated automatically or semi-automatically. Through a mechanical transmission system, the pole piece is transferred from a coiling device to a cutting device for processing. The transmission system of the cutting machine is equipped with a motor and a transmission device. After the pole piece is moved to a specified position, it is cut by a laser cutting head to complete the cutting of the lithium battery pole piece.

[0004] Although the existing lithium battery pole piece cutting machine can realize the basic automatic cutting function, there are still some problems in actual use. First, during the transportation and cutting of the pole piece, the pole piece is prone to position displacement due to uneven tension or mechanical transmission errors, which in turn affects the cutting accuracy and cannot always ensure the size consistency and edge neatness of the pole piece. Secondly, the existing cleaning device is relatively simple in design and fails to effectively remove dust on the surface of the pole piece, resulting in dust remaining in the cutting area, affecting the cutting quality. Finally, during the replacement or transportation of the coil, the pole piece is prone to loose fixation or insufficient tension, causing the pole piece to loosen or fall off, affecting the continuity and stability of the production line. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a lithium battery pole piece cutting machine and a method of using the same.

At the same time, the cleaning device can efficiently remove dust, ensure the cleanliness of the cutting area, and improve the cutting quality.

[0054] The present invention also provides a method for using a lithium battery electrode cutting machine, comprising the following steps:

[0055] Step 1: When in use, the disc of lithium battery pole pieces is placed on the periphery of the discharge roller 104. At this time, the rack plate 505 drives the gear 2 501 to rotate by driving the second cylinder 503, so that the inclined plate 502 is tilted. During the tilting process, the disc of lithium battery pole pieces will be fixed to prevent them from falling off. When replacement is needed, the second cylinder 503 is driven to drive the rack plate 505 to move in the opposite direction to retract the inclined plate 502.

[0056] Step 2: Open the top plate 2 103 and pass one end of the lithium battery pole piece between the two brush rollers 206, and make the tensioning mechanism 40 located on the upper side of the lithium battery pole piece and in contact with it, and then pass through the transport rod 1 109 and in contact with the rubber block 117. After the above operation is completed, the transport rod 2 110 and the transport rod 1 109 are rotated by the driving motor 106 to complete the transportation of the lithium battery pole piece. During the transportation, the two brush rollers 206 can be rotated by the cleaning mechanism 20 to clean the dust adsorbed on the outside of the lithium battery pole piece, and when the lithium battery pole piece moves to the bottom of the laser cutting head 118, the lithium battery pole piece can be cut by driving the cylinder 112;

[0057] Step 3: When the lithium battery pole piece is loose during transportation, the clockwork spring 405 will reset and rotate and drive the connecting rod 401 to rotate, so that the extrusion plate 403 is tilted, so as to tighten the lithium battery pole piece, thereby improving the cutting effect;

[0058] Step 4: By driving the vacuum pump 301, the dust outlet pipe 302 can absorb fine particles and dust in the air, thereby reducing the dust floating inside the device. At the same time, the filter box 305 is used to store larger particles. Since the dust outlet pipe 302 continuously blows air, the airflow generated will drive the small dust and particles inside the base 101 to float, so that they pass through the filter box 305, can be filtered and return to the air, and when cleaning is needed, the restriction of the filter box 305 can be released by flipping the flap 306, so that the filter box 305 can be pulled out and cleaned;

[0059] Step 5: When the transport rod 109 rotates, the fixed block 114 is driven to move, and under the action of the compression spring 115, the rubber block 117 is always in contact with the lithium battery pole piece, thereby limiting the lithium battery pole piece and avoiding the subsequent pulling force from dragging the lithium battery pole piece off the transport track after cutting.

[0060] Although 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.

10. A method for using a lithium battery pole piece cutting machine, characterized in that: A lithium battery pole piece cutting machine according to any one of claims 1 to 9, comprising the following steps: Step 1: When in use, the disc of lithium battery pole pieces is placed on the periphery of the discharge roller (104), and the rack plate (505) is driven by the second cylinder (503) to drive the second gear (501) to rotate, so that the inclined plate (502) is tilted. During the tilting process, the disc of lithium battery pole pieces is fixed to prevent them from falling off, and when replacement is needed, the rack plate (505) is driven by the second cylinder (503) to move in the opposite direction to retract the inclined plate (502); Step 2: Open the second top plate (103) and pass one end of the lithium battery pole piece between the two brush rollers (206), and at the same time make the tensioning mechanism (40) located on the upper side of the lithium battery pole piece and contact it, and then pass through the transport roller (109) and contact the rubber block (117). After the above operation is completed, the transport roller (110) and the transport roller (109) are rotated by the driving motor (106), thereby completing the transportation of the lithium battery pole piece. During the transportation, the two brush rollers (206) can be rotated by the cleaning mechanism (20), thereby cleaning the dust adsorbed on the outside of the lithium battery pole piece, and when the lithium battery pole piece moves to the bottom of the laser cutting head (118), the lithium battery pole piece can be cut by driving the cylinder (112); Step 3: When the lithium battery pole piece is loose during transportation, the spring spring (405) will reset and rotate and drive the connecting rod (401) to rotate, thereby tilting the extrusion plate (403) to tighten the lithium battery pole piece, thereby improving the cutting effect; Step 4: By driving the vacuum pump (301), the dust outlet pipe (302) can absorb fine particles and dust in the air, thereby reducing the dust floating inside the device. At the same time, the filter box (305) is used to store larger particles. Since the dust outlet pipe (302) continuously blows air, the airflow generated will drive the small dust and particles inside the base (101) to float, thereby passing through the filter box (305), filtering them and returning to the air. When cleaning is required, the restriction of the filter box (305) can be released by turning over the flap (306), so that the filter box (305) can be pulled out and cleaned; Step 5: When the transport rod 1 (109) rotates, the fixed block (114) is driven to move, and under the action of the compression spring 1 (115), the rubber block (117) is always in contact with the lithium battery electrode, thereby limiting the position of the lithium battery electrode and avoiding the subsequent pulling force from dragging the lithium battery electrode off the transport track after cutting.
