[0001] The utility model relates to the technical field of pole piece production, in particular to a mechanism for a film coil material device to pass over a roller, which is a roller cleaning mechanism. Background Art

[0002] For coil materials, especially film coil materials, in order to prevent the film from wrinkling during production, several rollers are needed to support the film material. During production, due to electrostatic adsorption and other reasons, dust in the air or on the material will be adsorbed on the surface of the roller, ultimately affecting the product quality (refer to Figure 6 ). Therefore, the roller surface needs to be cleaned regularly to avoid the occurrence of the above problems.

[0003] Currently, the cleaning measure for the roller surface is manual wiping at regular intervals by humans. This is inefficient, and for some positions, there is not enough space, and it is greatly affected by human factors, which is not conducive to improving the excellent rate of products.

[0024] Next, the present utility model will be further described in conjunction with the drawings.

[0025] An over-roller cleaning mechanism includes a bracket and double-sided tape, and also includes a pay-off reel, a take-up reel and a pressure wheel structure; the double-sided tape starts from the pay-off reel, bypasses the pressure wheel structure, and is wound by the take-up reel; at least one double-sided tape pay-off reel on each pay-off reel is an air-expanding shaft with damping, and the take-up reel is a slip shaft;

[0026] The adhesive surface of the double-sided tape faces an over-roller, and the double-sided tape is bonded to the pole piece on the over-roller;

[0027] As shown in the figure, a detection sensor is also arranged on the bracket. The detection sensor faces the position where the double-sided tape is bonded to the pole piece, and is used to detect the bonding situation of the double-sided tape on the pole piece; the alarm is electrically connected to the detection sensor.

[0028] On the double-sided tape, the base material with adhesive has a plurality of equally spaced partitions on the release paper.

[0029] The driving motor of the take-up reel is installed on the bracket and is used to drive the take-up reel to rotate; the detection sensor is electrically connected to the driving motor.

[0030] For the two bonding surfaces of the double-sided tape, the bonding surface with high viscosity is bonded to the surface of the pole piece, and the bonding surface with low viscosity cleans the stains on the over-roller.

[0031] Refer to Figure 4 , the pressure wheel structure includes a pressure wheel 5, a pressure wheel bracket 2, a spring 6 and a spring guide rod 1; the pressure wheel bracket is of a U-shaped structure, and chutes are arranged on both side plates thereof; both ends of the central shaft 4 of the pressure wheel are respectively located in the corresponding chutes; the spring guide rod is fixed on the middle top plate of the pressure wheel bracket, and a slide plate 3 is sleeved thereon. The spring is sleeved on the spring guide rod and one end abuts against the slide plate, and the other end abuts against the lower surface of the middle top plate;

[0032] Both ends of the slide plate are respectively located in the corresponding chutes and press on the corresponding ends of the central shaft.

[0033] There are multiple detection sensors, and the release paper of the double-sided tape is wound by the take-up roller.

[0034] This mechanism automatically pastes the double-sided tape onto the surface of the running material. Through the normal running of the material, the double-sided tape adheres to the particles on the surface of the over-roller F to achieve the effect of cleaning the roller surface.

[0035] See Appendix Figure 1 and Figure 2 , the double-sided tape is fixed on the pay-off mechanism A. A is an air-expanding shaft with damping. Through the pressure wheel mechanism B, the double-sided tape adheres to the surface of the material. The release paper of the double-sided tape is wound back by the take-up mechanism D. The take-up mechanism D is powered by the take-up motor E. The take-up mechanism D is a slip shaft. If the release paper is tightened, a continuous slip phenomenon will occur.

[0036] During normal operation, the entire mechanism is driven by a cylinder to move closer to the over-roller F, pressing the double-sided tape against the material. When the material runs, the material drives the double-sided tape paper to rotate, continuously sticking the double-sided tape to the surface of the material, and the detection sensor C (6) is used to identify whether the double-sided tape is stuck. There is a partition in the middle of the double-sided tape on the release paper ( Figure 3 ), and this type of tape can save the cutting action of the double-sided machine. The pressing wheel mechanism B can be adjusted independently in terms of position and pressing force, enabling the axial movement of the tape and the adjustment of the pressing force. The pressing wheel structure is connected to the bracket through a locking mechanism. The locking mechanism moves the position of the pressing wheel according to different pole piece sizes. After the position is determined, the locking handle can be operated (this is common knowledge and will not be elaborated here).

[0037] Refer to Figure 2 , taking the pole piece style of power battery in the lithium battery industry as an example, the pole piece 7 has a multi-coated style. The surface of the over-roller mainly contacts the coating area, and it is required that the surface is free of dust or stains. To enable the double-sided tape to clean the stains or dust in the coating area as soon as possible, several rolls of tape (4 tapes in the figure) can be fixed on the automatic tape sticking mechanism at the same time, and the starting positions of each roll of tape are the same. When the tape sticking action is performed, the four tapes are simultaneously stuck to the pole piece, and four sensors are used to respectively check whether the tape is stuck. When the four sensors simultaneously detect that there is no tape, it means that the double-sided tape has reached the partition, and at this time, the tape sticking action is completed, and the tape sticking machine can be moved away from the over-roller F. If the detection signals of the four sensors are inconsistent, it indicates that there is an abnormality in the tape sticking.

[0038] After the double-sided tape is stuck on both sides of the pole piece, through normal production, the pole piece drives the double-sided tape to clean the stains or dust on the surface of the over-roller, completing the action of automatically cleaning the roller surface.
