Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a wide-width pole piece smoothing structure. Background Art

[0002] Lithium battery is a battery that uses lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. It has the characteristics of high energy, long life, low consumption, pollution-free, and no memory effect. As an important component of lithium battery, electrode sheet needs to be cut and rolled to adapt to the battery model size. The lithium battery electrode sheet cutting device in the prior art uses a rotating cutter to cut the passing electrode sheet and roll it onto the corresponding rotating roller. The winding roller is pressed by a long roller bar, and the smoothing plate on the roller is fixed and fixed on the surface of the roller. If the electrode needs to be threaded, the smoothing plate needs to be disassembled in advance and then threaded. After the threading is completed, the smoothing plate needs to be installed back. This method is not only time-consuming, but also inefficient. Utility Model Content

[0006] As a preferred technical solution, the connecting bracket includes a first connecting rod, a second connecting rod, a rotating seat and a third connecting rod. The third connecting rod is rotatably set on the rotating seat, one end of the second connecting rod is hinged on the first connecting rod, and the other end is hinged on the third connecting rod. The guide plate is fixed on the third connecting rod.

[0007] As a preferred technical solution, the second connecting rod is provided with a long hole, and the third connecting rod is provided with a rotating shaft, and the rotating shaft moves in the long hole.

[0008] As a preferred technical solution, the guide plate includes a mounting portion, a guiding portion and a smoothing portion, the guiding portion is arranged at one end of the smoothing portion, the mounting portion is arranged at the other end of the smoothing portion, and the mounting portion is fixed to the third connecting rod.

[0009] The beneficial effects of the utility model are: the above-mentioned wide-width pole piece smoothing structure, when the pole piece is threaded, the cylinder contracts, so that the pole piece avoids the sprocket for threading, and after the threading is completed, the cylinder drives it to extend, and the pole piece is smoothed by the guide piece, thereby alleviating the situation of the pole piece being folded. The pole piece smoothing structure is simple and can be compatible with pole pieces of different widths. One cylinder can drive two guide pieces to move, saving costs, avoiding the traditional fixed structure, and making maintenance operations convenient and safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a structural schematic diagram of the wide-width pole piece smoothing structure involved in the utility model when smoothing the pole piece;

[0011] Figure 2 It is a schematic diagram of the structure of the wide-width pole piece smoothing structure involved in the utility model when threading. DETAILED DESCRIPTION

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] Please combine Figure 1 and Figure 2 As shown, a wide-width pole piece smoothing structure includes a sprocket 6, a guide roller 5, a cylinder bracket 1, a cylinder 2, a connecting bracket 3 and a guide piece 4. The cylinder 2 is installed on the cylinder bracket 1, the guide piece 4 is installed on the connecting bracket 3, and the sprocket 6 is installed on the guide roller 5. The cylinder 2 drives the connecting bracket 3 to move, so as to drive the guide piece 4 to move relative to the guide roller 5. When the pole piece needs to be threaded, the cylinder 2 drives the connecting bracket 3 to contract, and the connecting bracket 3 drives the guide piece 4 away from the guide roller 5, increasing the gap between the guide piece 4 and the guide roller 5, so that the pole piece a can avoid the sprocket 6. When the pole piece is threaded, the cylinder 2 drives the connecting bracket 3 to extend, and the connecting bracket 3 drives the guide piece 4 to be close to the guide roller 5, so as to smooth the pole piece a.

[0014] Specifically, the connecting bracket 3 includes a first connecting rod 31, a second connecting rod 32, a rotating seat 34 and a third connecting rod 33. The third connecting rod 33 is rotatably arranged on the rotating seat 34. One end of the second connecting rod 32 is hingedly arranged on the first connecting rod 31, and the other end is hingedly arranged on the third connecting rod 33. The guide piece 4 is fixedly arranged on the third connecting rod 33. The second connecting rod 32 is provided with a long hole 321, and the third connecting rod is provided with a rotating shaft 331. The rotating shaft 331 moves in the long hole 321. A spring is provided in the long hole 321. The spring abuts against the rotating shaft 331, so that the guide piece 4 can be in flexible contact with the pole piece a when in contact with the pole piece to smooth the pole piece.

[0015] Specifically, the guide piece 4 includes a mounting portion 43, a guide portion 41 and a smoothing portion 42. The guide portion 41 is disposed at one end of the smoothing portion 42, the mounting portion 43 is disposed at the other end of the smoothing portion 42, the mounting portion 43 is fixed to the third connecting rod 33, and the guide portion 41 guides the pole piece to between the smoothing portion 42 and the guide roller 5, so as to smooth the pole piece a. The guide piece 4 is an elastic member to prevent the guide piece 4 from colliding with the pole piece when in contact with the pole piece, thereby causing the pole piece to be worn.

[0016] The above-described embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
