Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a head glue winding device for a lithium battery protection plate. Background Art

[0002] According to the patent document with the publication number CN218632163U, the rotating assembly can drive the support rod to rotate, and the support rod drives the winch to rotate so that the head of the tape is first attached to the battery, and then the second bottom plate is driven to move by the moving assembly to pull the tape out to the required length, and finally the tape starts to rotate again. When the tape is wrapped around the battery, the cutter moves forward and backward and left and right to cut the tape;

[0003] The patent document requires that the tape be pulled out to a corresponding length first. However, when the longer tape is pulled out and wrapped around the lithium battery protection plate, it is easy for the tape to not correspond to or be offset from the protection plate. At the same time, the end of the tape will not be attached to the lithium battery after it is cut. At the same time, simple winding will prevent the tape from being bonded and fixed to the lithium battery and the protection plate, resulting in a loose bond between the tape and the protection plate.

[0031] The sticking mechanism 3 includes a sticking wheel 31, which is rotatably connected to the middle position of the frame 1. A buffer sleeve 32 is bonded to the front side of the sticking wheel 31, and a rotating air joint 33 is provided at the rear end of the sticking wheel 31. The rotating air joint 33 is connected to the negative pressure pump 34 through an air pipe. A driving mechanism 2 for driving the sticking wheel 31 to rotate is provided on the lower side of the sticking wheel 31. Both the sticking wheel 31 and the buffer sleeve 32 are provided with air ports for adsorbing the tape. The interior of the sticking wheel 31 is a cavity structure, and the air port of the sticking wheel 31 is connected to the cavity of the sticking wheel 31. The negative pressure pump 34 is used to evacuate the rotating air joint 33 through the air pipe, and then the rotating air joint 33 will extract the gas in the cavity of the sticking wheel 31, and then suction will be generated at the air port position of the sticking wheel 31 to adsorb and fix the cut tape.

[0032] In this embodiment: the driving mechanism 2 includes a driving motor 21, which is fixed to the rear side of the frame 1. A driving pulley 22 is fixed to the rotating part of the driving motor 21, and a driven pulley 23 corresponding to the driving pulley 22 is fixed to the adhesive wheel 31. The driving pulley 22 and the driven pulley 23 are connected by a synchronous belt 24. The driving pulley 22 is driven to rotate by the rotating part of the driving motor 21, and the driven pulley 23 is driven to rotate by the transmission of the synchronous belt 24, and then the adhesive wheel 31 is driven to rotate by the driven pulley 23.

[0033] In this embodiment: the tape feeding mechanism 5 includes a tape wheel 51, which is sleeved on the front end of the tape rod of the frame 1, and a squeezing roller 53 is arranged on one side of the tape wheel 51 to press against the sticking wheel 31, and a limiting roller 52 is arranged between the tape wheel 51 and the squeezing roller 53, and a shearing cylinder 54 fixed on the triangular support plate is arranged on the upper side of the tape wheel 51, and a shearing knife 55 is fixed on the telescopic part of the shearing cylinder 54, and the squeezing roller 53 follows the opposite rotation of the sticking wheel 31 to tear off the tape on the tape wheel 51, and in this process, the adhesive side of the tape is pressed against the outer side of the sticking wheel 31, and in addition, when the distance the tape is torn off is equal to the circumference of the lithium battery head, the shearing knife 55 is pushed toward the sticking wheel 31 by the telescopic part of the shearing cylinder 54 to cut the tape.

[0034] Working principle: When in use, first flip the pressing plate frame 45 to place the lithium battery to be wound with glue on the flip seat 44, and clamp the two sides of the lithium battery through the two clamping plates 46 on the flip seat 44. At this time, the protection plate of the lithium battery head faces backward, and the lithium battery protection plate just corresponds to the buffer sleeve 32. At this time, release the pressing plate frame 45 and press and fix the top of the lithium battery under the drive of its torsion spring;

[0035] Then, the tape wheel 51 is placed on the tape rod, and then the tape of the tape wheel 51 is passed around the lower side of the limiting roller 52 and inserted between the squeezing roller 53 and the buffer sleeve 32. At this time, the adhesive side of the tape is arranged toward the outside of the adhesive wheel 31, and at the same time, the rotating part of the driving motor 21 drives the active pulley 22 to rotate, and the active pulley 22 drives the driven pulley 23 to rotate through the transmission of the synchronous belt 24, and then the driven pulley 23 drives the adhesive wheel 31 to rotate, and at the same time, the negative pressure pump 34 is started to evacuate the internal cavity of the adhesive wheel 31 through the air pipe and the rotating air joint 33, and then suction is generated at the air ports of the adhesive wheel 31 and the buffer sleeve 32, and then the tape wrapped around the buffer sleeve 32 will be adsorbed on its outside;

[0036] When the distance of the tape wound on the buffer sleeve 32 is equal to the circumference of the lithium battery head, the telescopic part of the shearing cylinder 54 pushes the shearing knife 55 to cut the tape, and the above action is repeated to continue to wind the tape on the buffer sleeve 32;

[0037] In addition, the telescopic part of the hydraulic rod 41 drives the moving frame 42 to move toward the lower side of the sticking wheel 31, and then one end of the head of the lithium battery protection plate on the flip seat 44 is located at the lower side of the sticking wheel 31. During this process, the tape adsorbed on the outside of the buffer sleeve 32 will stick to the head of the lithium battery protection plate. As the hydraulic rod 41 moves to drive the middle position of the lithium battery and the axis of the sticking wheel 31 to be in the same plane, the rotating part of the flip motor 47 drives the flip seat 44 to rotate, and the lithium battery will form a counter-rotation with the sticking wheel 31, and the tape on the sticking wheel 31 will gradually wrap around the lithium battery protection plate. During this process, the flip seat 44 will allow the sliding seat 43 to move downward and compress the reset spring; when the lithium battery is flipped 90 degrees, the sliding seat 43 will no longer compress the reset spring downward. Spring, as the flip seat 44 drives the lithium battery to continue to flip, the return spring will push the sliding seat 43 to move upward, and make the lithium battery protection plate on the flip seat 44 completely fit the lower side of the buffer sleeve 32, when the flip seat 44 flips 180 degrees, the tape on the sticking wheel 31 will be stuck to the middle position of the lithium battery protection plate after flipping, and then the telescopic part of the hydraulic rod 41 continues to retract and let the movable frame 42 move toward the tape wheel 51, and then the remaining tape on the sticking wheel 31 is wound around the flipped lithium battery protection plate, when the flip seat 44 completely moves over the sticking wheel 31, the gluing process of the lithium battery protection plate can be completed; then the lithium battery is removed and the sliding seat 43 is reset by the hydraulic rod 41 to repeat the glue winding process of the head of the next lithium battery protection plate.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
