Technical Field

[0001] The utility model relates to the technical field of pole piece rolling, in particular to an automatic avoidance structure. Background Art

[0002] To meet the needs of customers, manufacturers of lithium battery pole pieces continuously improve the manufacturing process and types of pole pieces, and at the same time, the quality requirements are more stringent. In the production process of lithium battery pole pieces, pole piece rolling is an essential process. When rolling the pole piece, since there will be a situation of connecting tapes for the pole piece (that is, when changing the roll, the end of the previous tape is adhered to the end of the next tape through tape to realize the roll change of the tape), the pole piece will have a situation of uneven thickness, so when rolling, it is easy to cause tape breakage or damage to the main roll of the rolling device.

[0003] Therefore, it is necessary to propose a technical means to solve the above defects. Summary of the Utility Model

[0004] The utility model adopts the following technical scheme:

[0005] An automatic avoidance structure, comprising

[0007] A feeding device for conveying the tape so that the tape advances along a preset path and enters the rolling device for rolling;

[0008] A detection component installed on the preset path for monitoring the tape connection situation so that the rolling device releases pressure as needed.

[0009] Preferably, the detection component includes a first color mark sensor and a second color mark sensor arranged in sequence along the traveling direction of the tape on the preset path.

[0010] Preferably, the feeding device includes a plurality of guide wheels for driving the tape to travel along the preset path.

[0011] Preferably, the rolling device includes a rolling roller for rolling the tape

[0012] The automatic avoidance structure involved in the utility model can effectively avoid the occurrence of tape breakage or damage to the rolling roller after the connected tape passes through the rolling device for rolling when there is a tape connection situation, and is suitable for industrial applications through the settings of the rolling device, the feeding device and the detection device.

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 directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0017] Please refer to Figure 1 , an automatic avoidance structure, including

[0018] A rolling device 10 for rolling the strip A.

[0019] A feeding device 20 for conveying the strip A so that the strip A advances along a preset path and enters the rolling device 10 for rolling.

[0020] A detection component installed on the preset path for monitoring the tape splicing situation of the strip A so that the rolling device 10 releases pressure as needed.

[0021] Specifically, in combination with Figure 1, the working principle of the present utility model will be described. In this embodiment, when the detection component detects that there is a splicing situation of the strip A, the indicating roll pressing device 10 is depressurized. When the strip A successfully passes through the roll pressing device 10, the equipment stops, the roll pressing device 10 resumes the set pressure, and the equipment starts normally. Further, in this embodiment, the strip A is a pole piece.

[0022] An automatic avoidance structure involved in the present utility model, through the settings of the roll pressing device 10, the feeding device 20 and the detection device, can effectively avoid the situation of tape breakage or damage to the roll pressing roller 101 when the strip A has a splicing situation and the spliced part passes through the roll pressing device 10 for roll pressing, and is suitable for industrial applications.

[0023] In a specific embodiment, the detection component includes a first color mark sensor 30 and a second color mark sensor 40 arranged in sequence along the traveling direction of the strip A on the preset path.

[0024] Specifically, in this embodiment, during operation, the strip A advances along the preset path to the roll pressing device 10 for roll pressing. When the first color mark sensor 30 detects that there is a splicing of the strip A, the external device decelerates to reduce the running speed of the strip A; when the spliced part travels to the second color mark sensor 40 and is detected by the second color mark sensor 40, the roll pressing device 10 is depressurized until the spliced part successfully passes through the roll pressing device 10, then the whole equipment stops, the strip A stops running. At this time, the main cylinder 102 of the roll pressing device 10 is pressurized to the set pressure, and then the equipment restarts, and the strip A continues to travel normally.

[0025] In this embodiment, the detection component preliminarily detects the splicing of the strip A through the first color mark sensor 30, and then indicates the strip A to reduce the traveling speed, so that the second color mark sensor 40 can effectively and accurately identify the position of the spliced part, thereby ensuring that the spliced part can successfully pass through the roll pressing device 10 and improving the accuracy of the device.

[0026] In a specific embodiment, the feeding device 20 includes a plurality of guide wheels 201 for driving the strip A to travel along the preset path. The roll pressing device 10 includes a roll pressing roller 101 for roll pressing the strip A. Specifically, the roll pressing device 10 belongs to the prior art, and the technical solution will not be elaborated here.

[0027] An automatic avoidance structure involved in the present utility model, through the settings of the roll pressing device 10, the feeding device 20 and the detection device, can effectively avoid the situation of tape breakage or damage to the roll pressing roller 101 when the strip A has a splicing situation and the spliced part passes through the roll pressing device 10 for roll pressing, and is suitable for industrial applications.

[0028] The above embodiments only illustrate several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
