[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0021] like Figure 1-5 As shown, a winding machine lug rubber coating mechanism includes a lug seat 1, a roller 2, a roller seat 3, and a roller lateral movement force element 4. An inner blowing hole 5 is provided on one side of the upper surface of the lug seat 1 and an outer blowing hole 6 is provided on the other side. There are a plurality of inner blowing holes 5 and outer blowing holes 6, respectively. The inner blowing holes 5 and the outer blowing holes 6 are separated and use different air passages. The lug 7 passes between the inner blowing holes 5 and the outer blowing holes 6. The tape 8 is located below the lug 7 and is placed on the inner blowing holes 5 and the outer blowing holes 6. The adhesive side of the tape 8 is facing upward and adheres to the bottom surface of the lug 7. The left side of the tape 8 covers the inner blowing hole 5, and the right side of the tape 8 covers the outer blowing hole 6. The roller 2 is installed on the roller seat 3, and the roller 2 is located above the lug seat 1. The roller lateral movement force element drives the roller seat 3 to move, and the roller seat 3 drives the roller 2 to move, and the roller 2 rolls the blown tape 8 onto the lug.

[0022] Specifically, a tab pressing block 9 is provided above the tab seat 1, and the two ends of the bottom of the tab pressing block 9 are protruding. The tab pressing block lifting power element 10 drives the tab pressing block 9 to press the front and rear ends of the tab 7 to prevent the tab from being displaced during rubber coating. The roller transverse movement power element 4 and the tab pressing block lifting power element 10 are cylinders respectively.

[0023] like Figure 5 and 6 As shown, the process of tab rubber coating is that first, the inner blowing hole 5 blows up the inner tape, and the roller 2 moves outward for the first time to roll the blown inner tape, and the inner tape will stick to the tab. Then, the outer blowing hole 6 blows up the outer tape, and the roller 2 moves inward for the second time to roll the blown outer tape. In addition, the roller seat 3 is provided with a sufficiently large avoidance groove to avoid affecting the outer blowing hole 6 from blowing up the outer tape.
