Description

Technical Field

[0001] The utility model relates to the technical field of battery core packaging equipment, in particular to a battery core glue supply mechanism. Background Art

[0002] With the development and maturity of new energy technologies, the application of lithium batteries is becoming increasingly widespread. In current lithium battery equipment, batteries composed of cells assembled in a wound manner are called wound batteries, also known as cells. Existing lithium battery automatic winding machines or film-making machines use a gluing device to apply adhesive tape to the electrode sheets. The electrode sheet gluing process requires adhesive preparation and then application. Existing adhesive preparation equipment directly pulls the adhesive to a set length from a tape reel, which requires a relatively strong pull force and is prone to adhesive breakage.

[0003] The utility model with publication number CN217534925U discloses a battery cell glue supply mechanism, including a mounting plate, on which are provided a glue pulling and pressing mechanism, a glue cutting mechanism, a guide roller buffer mechanism, a feed tray and a rotary glue taking and applying mechanism. The glue pulling and pressing mechanism pulls the tape to the position of the rotary glue taking and applying mechanism and presses the tape. The glue cutting mechanism cuts the tape. The guide roller buffer mechanism buffers the tape. The guide roller buffer mechanism is located between the glue cutting mechanism and the feed tray. The glue cutting mechanism is located between the glue pulling and pressing mechanism and the guide roller buffer mechanism. The utility model is provided with a guide roller buffer mechanism. The length of the tape pulled out each time by the glue pulling and pressing mechanism is equal to the length of the tape buffered by the guide roller buffer mechanism. After the tape is buffered, the pulling force of the glue pulling and pressing mechanism to pull the tape can be reduced, the phenomenon of tape breakage can be prevented, and the stability of glue supply is improved.

[0004] The above existing solution has the following problem: when the adhesive tape is pulled out to the guide roller buffer mechanism for buffering, the pull tape is also subjected to a large pulling force, and the adhesive tape is still prone to breaking. Utility Model Content

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model provides a technical solution: a battery cell glue supply mechanism, including a mounting plate 1 and a transmission mechanism. A fixed roller 2 is fixedly mounted on the mounting plate 1, a sleeve 3 is rotatably sleeved on the fixed roller 2, a sealing plate 4 for limiting the sleeve 3 is fixed on the upper end of the fixed roller 2, a pressing plate groove 10 is opened on the outer wall of the fixed roller 2, and four are evenly arranged along the outer wall of the fixed roller 2, a pressing plate 11 is provided in the pressing plate groove 10 for abutting against the inner wall of the sleeve 3, and a sliding groove 12 is opened at the bottom of the four pressing plate grooves 10. A sliding rod 13 fixedly connected to the pressure plate 11 is provided in the sliding groove 12, and a control groove 14 connected to the four sliding grooves 12 is coaxially opened in the center of the fixed roller 2. A control rod 15 for controlling the sliding of the sliding rod 13 is provided in the control groove 14. A knob 5 for controlling the sliding of the control rod 15 is provided on the sealing plate 4. A plurality of tensioning rollers 6 are rotatably provided on the side of the fixed roller 2 on the mounting plate 1. A motor 9 fixedly connected to a tensioning roller 6 at the output end is fixed on the rear side of the mounting plate 1, and each tensioning roller 6 is linked through a transmission mechanism.

[0022] The control slot 14 is square in cross section, ensuring that the four slide bars 13 remain in the same position after being acted upon by the control rod 15.

[0023] Specifically, the outer wall of the control rod 15 is in contact with the inner wall of the control groove 14 to prevent the control rod 15 from rotating in the control groove 14. A threaded groove 16 is provided on the side wall of the control rod 15 away from the slide rod 13, and a screw 17 is connected to the inner thread of the threaded groove 16. A rotating groove 18 for the screw 17 to pass through and rotatably connected to the screw 17 is provided on the side of the control groove 14 away from the slide rod 13. The knob 5 is fixedly connected to one end of the screw 17 located outside the sealing plate 4. Turning the knob 5 drives the screw 17 to rotate, and the control rod 15 slides in the control groove 14 through the threaded connection between the screw 17 and the threaded groove 16.

[0024] Specifically, a bearing 19 whose inner ring is fixedly connected to the outer wall of the screw 17 is rotatably embedded in the inner wall of the rotating groove 18 to prevent the screw 17 from axial movement.

[0025] Specifically, a limit block 24 is fixedly provided at the end of the clamping plate 11 away from the sleeve 3, and a limit groove 23 is provided at the bottom of the clamping plate groove 10 for the limit block 24 to slide. By setting the limit block 24 and the limit groove 23, the stability of the clamping plate 11 sliding out of the clamping plate groove 10 is improved.

[0026] Specifically, the transmission mechanism includes a tensioning roller gear 7. There are three tensioning rollers 6 and they are arranged in a triangular shape. The tensioning roller gear 7 is fixedly sleeved on each tensioning roller 6 and meshes with each other. The motor 9 drives one tensioning roller 6 to rotate. The three tensioning rollers 6 are linked by the meshing of the tensioning roller gears 7. The rotation directions of the tensioning rollers 6 on both sides are the same, and the rotation direction of the middle tensioning roller is opposite to that of the tensioning rollers 6 on both sides. The tape can be conveyed to reduce the resistance when the tape is pulled out. A baffle 8 is fixedly sleeved on the outside of the tensioning roller gear 7 on the tensioning roller 6 to prevent the tape from touching the tensioning roller gear 7.

[0027] A specific application example of this embodiment is:

[0028] When the device is in use, the feed tray is fixedly mounted on the sleeve 3, and the pulled tape is passed over the upper tensioning roller 6, then passed under the lower tensioning roller 6, and finally passed over the other tape, and then led to the rubber pulling and rolling mechanism, rubber cutting mechanism, and rotary rubber taking mechanism on the front side (this is the prior art of the comparative document). The knob 5 is turned to drive the screw 17 to rotate, and the screw 17 is threadedly connected to the threaded groove 16 to make the control rod 15 slide in the control groove 14. The sliding force of the control rod 15 is applied to the slide rod 13. The inclined surface causes the slide rod 13 to slide so that the pressure plate 11 extends out and abuts against the inner wall of the sleeve 3, thereby adjusting the rotational resistance of the sleeve 3, thereby adjusting the tension of the tape when it is pulled out from the feed disk. Different tensions can be adjusted according to the materials of different tapes, so that the tape will not break while maintaining sufficient tension. When the tape is fed, the motor 9 is started. The motor 9 can be set to be controlled simultaneously with the front-end glue pulling and rolling mechanism, so that the three tensioning rollers 6 rotate to convey the tape, thereby reducing the tension of the tape and avoiding the phenomenon of tape breaking.
