[0017] The beneficial effects of this utility model are:

[0018] 1. This utility model provides an automatic belt adjustment device. By setting up a swing mechanism, when the electrode belt deviates, the first driving member drives the first connecting seat and the roller to swing at a certain angle to adjust the belt swing angle of the electrode.

[0026] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0027] Reference Figures 1 to 3 An example of this utility model provides an automatic belt adjustment device, which includes a swing mechanism 100 and a belt pressing mechanism 200.

[0028] The swing mechanism 100 is used to adjust the belt travel angle of the electrode sheet. The swing mechanism 100 includes a correction base 110, a first connecting seat 120, a guide roller 130 and a first driving member 140. The guide roller 130 is connected to the first connecting seat 120, and the first driving member 140 is disposed on the correction base 110. The first driving member 140 is used to drive the first connecting seat 120 to swing, and the guide roller 130 is used to support the electrode sheet.

[0029] When the electrode tape deviates from its original direction, the first driving component 140 drives the first connecting seat 120 and the guide roller 130 to swing together at a certain angle to adjust the tape walking angle of the electrode. This allows the electrode tape to automatically return to the normal state from the deviated state, thereby improving the alignment of the two sides of the bare cell and ensuring the winding quality of the bare cell.

[0030] Furthermore, the pressing mechanism 200 is used to press the electrode sheet onto the roller 130. Structurally, the pressing mechanism 200 includes a second connecting seat 210, a pressure roller 220 rotatably connected to the second connecting seat 210, and a second driving member 230 for driving the second connecting seat 210 closer to or away from the roller 130. The second driving member 230 is disposed on the first connecting seat 120. The pressure roller 220 and the roller 130 are parallel to each other. The second driving member 230 drives the second connecting seat 210 and the pressure roller 220 to move closer to the roller 130 as a whole, so that the pressure roller 220 presses the electrode sheet onto the roller surface of the roller 130. Thus, it can be ensured that the electrode sheet always keeps in contact with the roller surface of the roller 130 and prevent slippage.

[0031] In some preferred embodiments, the first driving component 140 includes a motor 141 and a reducer 142. The motor 141 is directly connected to the reducer 142. The output end of the reducer 142 is connected to the first connecting seat 120. The reducer 142 is mounted on the correction base 110.

[0032] Understandably, the reducer 142 can reduce the output speed of the motor 141 and increase the output torque, thereby facilitating precise control of the rotation angle of the first connecting seat 120 and improving the adjustment accuracy.

[0033] Furthermore, the output end of the reducer 142 is provided with a third connecting seat 143, and the first connecting seat 120 is installed on the third connecting seat 143, thereby facilitating the installation and disassembly of the first connecting seat 120 and improving assembly efficiency.

[0034] In some preferred embodiments, the first connecting seat 120 includes a horizontal plate 121 and two side plates 122, the two side plates 122 are respectively connected to the two ends of the horizontal plate 121, the middle part of the horizontal plate 121 is connected to the third connecting seat 143, the two ends of the roller 130 are respectively connected to the two side plates 122, and the roller 130 is parallel to the horizontal plate 121.

[0035] It is understandable that a horizontal plate 121 and two side plates 122 are combined to form a U-shaped frame, so that the roller 130 is installed at the opening of the U-shaped frame, thereby allowing the roller 130 to be suspended in the air and avoiding interference between the first connecting seat 120 and the electrode sheet during the tape feeding process.

[0036] Furthermore, the roller 130 includes a cantilever shaft 131 and a roller 132 rotatably connected to the outer periphery of the cantilever shaft 131. The two ends of the cantilever shaft 131 are fixedly connected to two side plates 122 respectively. The electrode sheet abuts against the roller 132. When the belt is running, the cantilever shaft 131 is fixed and the roller 132 rotates.

[0037] Specifically, the cantilever shaft 131 and the roller 132 are rotatably connected by bearings. On the one hand, this allows the roller 132 to rotate smoothly, and on the other hand, it reduces the wear of the cantilever shaft 131 and the roller 132, thus improving their service life.

[0038] Furthermore, both ends of the roller 132 are provided with inner bearing pressure rings 133, which are used to limit the bearings, thereby preventing the bearings from loosening or shifting, reducing vibration, and improving stability.

[0039] In some preferred embodiments, a guide sheet metal part 150 is installed on the inner side of one of the side plates 122. The guide sheet metal part 150 is located on the radial side of the roller 132. The guide sheet metal part 150 is arc-shaped and is used to guide the electrode sheet, thereby enabling the electrode sheet to move in a fixed direction and improving the stability of the electrode sheet during belt travel.

[0040] In some preferred embodiments, the second driving member 230 includes a cylinder, which is mounted on the horizontal plate 121 via a cylinder mounting seat 240. A second connecting seat 210 is provided at the telescopic end of the cylinder. The cylinder telescopically moves the second connecting seat 210 and the pressure roller 220 closer to or further away from the roller 130. The cylinder has a simple structure, is easy to install, and reduces the manufacturing cost of the equipment.

[0041] In some preferred embodiments, a fiber optic mounting plate 160 is provided on one side of the correction base 110. The fiber optic mounting plate 160 is used to mount a photoelectric sensor (not shown in the figure). The photoelectric sensor is used to sense the travel angle of the electrode sheet. The photoelectric sensor is electrically connected to the motor 141. When the electrode sheet travels off track, the photoelectric sensor detects the specific offset angle of the electrode sheet. The photoelectric sensor transmits the detected data to the motor 141. The motor 141 controls the rotation speed according to the offset angle of the electrode sheet, thereby improving the adjustment accuracy and ensuring the normal travel of the electrode sheet.

[0042] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
