Description

Technical Field

[0001] The utility model relates to the field of lithium battery production, in particular to a pole piece protection tape flying sticking device. Background Art

[0002] During the lithium battery production and winding process, tapes are pasted on the upper and lower surfaces of the electrode. The existing tape pasting device mainly includes an upper tape releasing mechanism, an upper tape cutting mechanism, an upper flat pasting mechanism, a lower tape releasing mechanism, a lower tape cutting mechanism, and a lower flat pasting mechanism. The upper tape releasing mechanism drives the upper tape to be unwound to the upper tape cutting mechanism, the upper tape cutting mechanism cuts the upper tape, and then the upper flat pasting mechanism flattens the tape onto the upper surface of the electrode. The lower tape releasing mechanism drives the lower tape to be unwound to the lower tape cutting mechanism, the lower tape cutting mechanism cuts the lower tape, and the lower flat pasting mechanism flattens the tape onto the lower surface of the electrode, which basically meets the glue pasting requirements. However, the applicant found during use that the electrode needs to stop conveying to wait for glue pasting, which prolongs the battery cell processing time. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0016] 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.

[0017] like Figures 1 to 4 As shown, a pole piece protection tape flying sticking device comprises a mounting plate 1, an upper tape putting out mechanism 2, an upper tape cutting mechanism 3, a lower tape putting out mechanism 4, a lower tape cutting mechanism 5, an upper tape flipping flying sticking mechanism 6 and a lower tape flipping flying sticking mechanism 7. The upper tape putting out mechanism 2 and the upper tape cutting mechanism 3 are installed on the upper front side of the mounting plate 1. The upper tape putting out mechanism 2 drives the upper tape to unwind to the upper tape cutting mechanism 5, and the upper tape cutting mechanism 5 cuts the upper tape. The lower tape putting out mechanism 4 and the lower tape cutting mechanism 5 are installed on the lower front side of the mounting plate 1. The lower tape putting out mechanism 4 drives the lower tape to unwind to the lower tape cutting mechanism 5, and the lower tape cutting mechanism 5 cuts the lower tape. The upper tape putting out mechanism 2, the upper tape cutting mechanism 3, the lower tape putting out mechanism 4, the lower tape cutting mechanism 5, the upper tape flipping flying sticking mechanism 6 and the lower tape flipping flying sticking mechanism 7 are all prior art specific structural principles and will not be repeated.

[0018] Specifically, a pole piece outlet 1a is provided in the middle of the mounting plate 1, and the pole piece 8 is output from the pole piece outlet 1a. An upper tape flipping and flying sticking mechanism 6 is installed in front of the mounting plate 1, and the upper tape flipping and flying sticking mechanism 6 is located between the upper tape cutting mechanism 3 and the pole piece 8 outlet. A lower tape flipping and flying sticking mechanism 7 is installed in front of the mounting plate 1, and the lower tape flipping and flying sticking mechanism 7 is located between the lower tape cutting mechanism 5 and the pole piece outlet 1a. The upper tape flipping and flying sticking mechanism 6 flips the cut upper tape 180° and rolls it to the upper surface of the pole piece 8, and the lower tape flipping and flying sticking mechanism 7 flips the cut lower tape 180° and rolls it to the lower surface of the pole piece.

[0019] Preferably, Figure 3As shown, the upper adhesive tape flipping and flying mechanism 6 includes a servo motor 61, a reducer 62, a rear bearing seat 63, a coupling 64, a rotating shaft 65, a rotating seat 66 and a glue suction disc 67. The rear bearing seat 63 is fixedly installed on the mounting plate 1. The reducer 62 and the servo motor 61 are installed behind the rear bearing seat 63. The servo motor 61 drives the reducer 62 to start. The output shaft of the reducer is connected to the rotating shaft 65 through the coupling 64. The rotating shaft 65 is fixedly connected to the rotating seat 65. A glue suction disc 67 is installed at the end of the rotating seat 65. The glue suction disc 67 is provided with a plurality of material suction micropores. The reducer 62 drives the rotating shaft 65 to rotate 180 degrees. The rotating shaft 65 causes the rotating seat 66 to rotate 180 degrees. The rotating seat 66 drives the glue suction disc 67 to rotate 180 degrees and rotates downward, and the adhesive tape is rolled onto the surface of the pole piece.

[0020] Preferably, the upper tape flipping and flying mechanism 6 also includes a front bearing seat 68, which is fixedly installed on the mounting plate 1, and the front end of the rotating shaft 65 rotates and extends into the front bearing seat 68. A bearing is installed inside the front bearing seat 68, and the front bearing seat 68 improves the stability of rotation.

[0021] Preferably, Figure 4 As shown, the adhesive suction disc 67 is provided with a avoidance groove 67a inside, and all the suction micropores face the avoidance groove 57a. Due to the different widths of different adhesive tapes, when the adhesive tape with a narrow width is to be adsorbed, not all the suction micropores are used. At this time, some of the suction micropores need to be blocked. Since all the suction micropores face the avoidance groove 57a, some of the holes can be blocked by inserting a blocking block of a suitable size into the avoidance groove 67a (for example, if only half of the suction micropores are needed, a blocking block with a volume equivalent to half of the avoidance groove 67a can be pasted into the avoidance groove 67a), which is simple and convenient to operate. In addition, the outer side surface of the suction micropores of the adhesive suction disc 67 is arc-shaped, which is convenient for the adhesive tape to contact the electrode when turning over.

[0022] Specifically, the upper adhesive tape flipping and flying sticking mechanism 6 and the lower adhesive tape flipping and flying sticking mechanism 7 have the same structure, the same principle of parts, and the only difference is the installation position and the direction of rotation.
