TECHNICAL FIELD

[0001] The present application relates to the field of battery cell production and manufacturing, in particular to a tape head holding mechanism used when pasting a tape on a battery cell. BACKGROUND

[0002] In the production process of a battery cell, there is a process of pasting a tape on the surface of the battery cell. In this process, a tape head holding mechanism is used to fix the tape head, and then the subsequent tape cutting process and tape pasting process are carried out. As a tape head holding mechanism, a clamp roller is usually used to clamp the tape head.

[0003] However, the tape head holding mechanism has the following problems: the clamp roller cannot clamp the tape tightly, the tape is easy to come off from between the clamp rollers; the clamp roller is easy to wear and needs to be replaced frequently; the tape head is easy to warp along the surface of the clamp roller and may be pasted on the roller shaft or other parts, resulting in the failure to carry out the subsequent process of pasting on the battery cell. SUMMARY

[0027] Hereinafter, the present application will be described in detail with reference to the drawings.

[0028] Figure 1 is a cross-sectional view of the tape head holding mechanism according to an embodiment of the present application. As shown in the figure, the tape head holding mechanism 1 is composed of a stopper bar 2, a stopper bar support mechanism 3, a pressing block 4, a pressing block driving mechanism 5, and a buffer member 6. Figure 1

[0029] The stopper bar support mechanism 3 is provided at both ends of the stopper bar 2 to support and fix the stopper bar 2. The stopper bar support mechanism 31 provided at the left end of the stopper bar 2 is composed of a support seat 71 and a stop screw 8 as a stopper member, and the stop screw 8 fixes the left end of the stopper bar 2 to the support seat 71 so that the stopper bar 2 cannot move in the axial direction and rotate. The stopper bar support mechanism 32 provided at the right end of the stopper bar 2 is composed of a support seat 72 and a bearing 9, and the right end of the stopper bar 2 is formed with a shaft neck portion having a circular cross section, which is supported by the bearing 9.

[0030] The pressing block 4 is formed in a square block shape. The pressing block 4 is connected to a circular columnar pressing rod 41 by adhesion or assembly, and the pressing rod 41 is inserted into the pressing block driving mechanism 5. The circular column 41 is connected to the pressing block driving mechanism 5 via the circumferentially surrounding spring 6. The top end of the pressing block 4 has a flat square pressing surface, and the pressing surface can be brought into abutment with or separated from the stopper bar 2. The pressing block driving mechanism 5 moves the pressing rod 41 up and down via the spring 6, and when the pressing rod 41 abuts on the stopper bar 2 via the pressing block 4, the spring 6 functions as a buffer.

[0031] Figure 2 is a side view of the tape head holding mechanism according to an embodiment of the present application.

[0032] The stopper bar 2, as shown in the figure, is a multi-ribbed shaft having a square cross section, and the side surfaces thereof serve as abutment surfaces for the tape 10 and are covered with an anti-sticking coating 21 formed by, for example, NACO2 anti-sticking treatment. Here, it is shown that the four side surfaces of the multi-ribbed shaft 2 are covered with the anti-sticking coating, so that when the anti-sticking coating of one side surface for abutting on the tape 10 is peeled off, another side surface can be used instead, and of course, the anti-sticking coating can be applied only to one side surface. Figure 2

[0033] ​​The tape head of the tape 10 passes between the stopper 2 and the pressing surface of the pressing block 4 from the lower right to the upper left of the paper in the tape conveying direction A, and when the tape 10 passing reaches a predetermined length, the pressing block 4 is moved toward the stopper 2 to press the tape 10 against the surface of the stopper 2. The pressing surface of the pressing block 4 and the flat surface of the stopper 2 can press the tape head straight, the tape head is reliably positioned and not easily warped, and the pressing block and the stopper are not easily worn. Thereafter, the tape is adhered to the surface of the battery cell 11 through a cutting process and an adhering process.

[0034] In the tape conveying direction A, the surface of the stopper 2 opposite to the pressing block 4 is more toward the front in the tape conveying direction A than the pressing surface of the pressing block 4. Thus, the cut tape head can be reliably prevented from adhering to the battery cell or the stopper 2 in the direction of the battery cell 11. It is preferable that the length of the stopper 2 in the tape conveying direction A be longer than the length of the pressing block 4 in the tape conveying direction A.

[0035] In the case where one side of the stopper 2 is worn due to long-time use, the stopper screw 8 can be removed and the stopper 2 can be rotated so that the other side is opposite to the pressing block. Thus, the use rate of the stopper 2 can be improved and the service life can be extended.

[0036] The above describes one embodiment of the tape head holding mechanism of the present application, but the present application is not limited to the above-described embodiment and various modifications can be made without departing from the gist of the present application.

[0037] In the above embodiment, the stopper 2 is composed of a multi-prong shaft, but is not limited thereto and can be composed of a three-prong shaft, a five-prong shaft, or the like, or a flat surface can be formed on a round shaft. As long as the surface contact with the pressing surface of the pressing block 4 is possible, it is acceptable.

[0038] In the above embodiment, one end of the stopper is supported by the support base and the other end is supported by the bearing, but is not limited thereto and both ends can be supported by the bearing or both ends can be supported by the support base and positioned by the stopper screw.

[0039] In the above embodiment, the pressing block driving mechanism 5 is connected to the pressing block 4 via the spring 6, but is not limited thereto and other structures, such as a buffer pad, can be used as long as the buffering function between the pressing block driving mechanism 5 and the pressing block 4 is possible.
