Description

Technical Field

[0001] The present application relates to the technical field of lithium battery processing, and in particular to a cylindrical power lithium battery capping machine. Background Art

[0002] During the production and processing of lithium batteries, the cap is an important component of lithium batteries. The production of lithium battery caps generally involves encapsulating the top cover, nickel ring, and explosion-proof disk in a sealing ring. Before encapsulation, the explosion-proof disk must be edged to wrap the explosion-proof disk on the top cover. The lithium battery cap edge wrapping machine is a commonly used machine in the edge wrapping process. It uses high-speed side roll forming technology, which limits and fixes the upper and lower ends of the workpiece, and uses an edge wrapping roller to roll the edge of the workpiece to make its edge smooth and flat, thereby improving the quality of the lithium battery cap.

[0003] However, the existing lithium battery capping and edging machines still have some defects during use: first, during the edging process, the ejecting cylinder will push the movable rod downward, and the limit piece at the end of the movable rod will press against the upper end surface of the workpiece to prevent the workpiece from being thrown out during high-speed rotation. However, in actual use, the limit piece does not have a self-rotation function, so that the limit piece will produce friction with the upper end surface of the workpiece, which may cause scratches on the surface of the workpiece; secondly, if the limit piece is not on the same vertical axis as the workpiece, the friction area between the limit piece and the workpiece will increase, increasing the possibility of damage to the workpiece; in addition, after the limit piece has been used for a long time, dust and impurities will adhere to the surface of the limit piece, thereby increasing the roughness between the two, intensifying the friction on the workpiece and affecting the processing quality of the workpiece.

[0080] The working principle of the method of the present invention is as follows:

[0081] When the workpiece needs to be hemmed, first rotate the rotating disk 12, use a conveying component 10 to load the material, so that the workpiece is placed on the fixed component 2, and then rotate the rotating disk 12 again to make the fixed component 2 reach the bottom of the supporting mechanism 3. At this time, the positioning block 42 emits infrared rays. If the positioning ring 22 does not receive the infrared rays, it indicates that the fixed component 2 and the movable component 6 are not on the same vertical axis. The control system needs to control the fixed component 2 to adjust the position. If the positioning ring 22 receives the infrared signal, it transmits the signal to the control system, so that the control system controls the ejection component 4 to start. At this time, the movable component 6 is pushed down until the end face of the movable component 6 contacts the upper end face of the workpiece. At the same time, rotate the hemming roller assembly 30 so that the hemming roller assembly 30 is against the workpiece. The edge of the workpiece, after the preparation work is completed, start the fixed component 2 so that the fixed component 2 drives the workpiece to rotate at a high speed, so that the hemming roller component 30 will generate an extrusion force on the workpiece to hem the edge of the workpiece, and at the same time start the movable motor 63 to make the lower movable rod 62 move synchronously with the workpiece, so that the lower movable rod 62 only applies a downward extrusion force to the workpiece, thereby not generating friction on the upper end surface of the workpiece, thereby preventing damage to the surface of the workpiece; in addition, since the movable component 6 and the workpiece located on the fixed component 2 are on the same vertical axis, the contact area between the movable component 6 and the workpiece is effectively prevented from expanding, thereby further improving the protection of the workpiece surface; when the supporting mechanism 3 completes the hemming of the workpiece, the rotating disk 12 rotates again and moves to another conveying component 10, thereby performing a material unloading operation on the workpiece.

[0082] When the movable component 6 moves from top to bottom along the long groove, when the rotating component 9 is located in the upper block 53 area, the rotating rod 91 is affected by the magnetic attraction of the upper block 53, so that the rotating rod 91 will overcome the magnetic attraction between the two rotating rods 91 and be in an extended state, so that one end of the rotating rod 91 with the rotating tooth block 94 is engaged with the auxiliary tooth block 52 of the auxiliary component 51. At this time, the rotating component 9 moves downward and rotates by itself, thereby driving the limit component 8 to rotate, causing the wall surface of the limit component 8 to rub against the deformation component 7. The continuous deformation of the deformation component 7 effectively cleans the dust and impurities attached to the limit component 8, preventing the limit component 8 from being attached with dust and increasing the gap between the workpiece. The roughness of the workpiece surface is improved, and the protection of the workpiece surface is improved. When the rotating component 9 is located in the lower block 54 area or below the auxiliary component 5, the rotating component 9 is moved toward the limiting component 8 by the magnetic repulsion force of the lower block 54 until it is in a retracted state. During this process, the rotating component 9 squeezes the limiting bag 82, so that the gas in the limiting bag 82 is discharged from the vertical air pipe 83, and the upper end face of the workpiece located below the limiting component 8 is effectively blown, and the roughness between the movable component 6 and the workpiece is further reduced, and the protection of the workpiece surface is further improved. When the workpiece is processed, the movable component 6 moves up to make the rotating component 9 mesh with the auxiliary component 5 again, and the limiting component 8 is cleaned again.
