[0026] For details, please see Figure 2 and Figure 5The cutter assembly 3 includes a cutter 31, a connecting plate 32, and a cutter drive 33. The cutter 31 is rotatably mounted on the connecting plate 32, and the cutter drive 33 is used to drive the connecting plate 32 to rise and fall. The cutter drive 33 is also mounted on the mounting bracket 5. The transfer wheel assembly 4 includes a transfer wheel 41, a bracket 42, and a transfer wheel drive 43. The transfer wheel 41 is rotatably mounted on the bracket 42, and the bracket 42 is mounted on the mounting bracket 5. The transfer wheel drive 43 is used to drive the transfer wheel 41 to rotate. The mounting bracket 5 is mounted on a translation drive 1, which is used to drive the mounting bracket 5 to move horizontally. The translation drive 1 is also mounted on a lifting drive 2, which is used to drive the translation drive 1 to move vertically. The connecting plate 32 is raised and lowered by the cutter drive 33, and the connecting plate 32 drives the cutter 31 to rise and fall. During the raising and lowering of the cutter 31, the electrode sheet is cut. The transfer wheel 41 is driven to rotate by the transfer wheel drive 43. The unwanted part of the electrode sheet after cutting is transported away by the transfer wheel 41. During the process of the lifting drive 2 driving the translation drive 1 to move in the vertical direction, the translation drive 1 drives the mounting frame 5 to move in the vertical direction. The translation drive 1 can also drive the mounting frame 5 to move in the horizontal direction. The horizontal and vertical movement of the mounting frame 5 drives the horizontal and vertical movement of the cutter 31 and the transfer wheel 41. Therefore, the horizontal and vertical movement of the cutter 31 and the transfer wheel 41 is controlled by the same set of translation drive 1 and lifting drive 2, which simplifies the structure and reduces production costs.

[0027] Please see Figure 1 and Figure 5 The transfer wheel drive component 43 includes a reduction motor 431, a drive wheel 432, a first belt 433, a driven wheel 434, a rotating shaft 435, several first pulleys 436, several second belts (not shown in the figure), and several tensioning pulleys 437. The reduction motor 431 is mounted on the stator of the translation drive component 1, and the rotating shaft 435 is rotatably mounted on the stator of the translation drive component 1.

The transmission shaft 411 is connected to the second pulley 412. The first pulleys 436 are connected to the second pulleys 412 through the second belts. The drive wheel 432 is driven to rotate by the geared motor 431. Under the action of the first belt 433, the drive wheel 432 drives the driven wheel 434 to rotate. The driven wheel 434 drives the rotating shaft 435 to rotate. The rotating shaft 435 drives the first pulley 436 to rotate. Under the action of the second belt, the first pulley 436 drives the second pulley 412 to rotate, so that the transmission shaft 411 drives the transfer wheel 41 to rotate.

[0028] Furthermore, several tensioning pulleys 437 are respectively mounted on several mounting brackets 5, and the tensioning pulleys 437 press against one side of the second belt. The tensioning pulleys 437 are used to control the tension of the second belt, ensuring the reliability of the transmission between the first pulley 436 and the second pulley 412.

[0030] The bracket 42 is connected to the mounting frame 5 via a transfer wheel lifting component 51. The transfer wheel lifting component 51 drives the bracket 42 to move vertically. The transfer wheel lifting component 51 includes a slide cylinder 511, which is mounted on the mounting frame 5. The output end of the slide cylinder 511 is connected to the bracket 42. The slide cylinder 511 allows for independent control of the lifting and lowering of the bracket 42, thereby independently controlling the height of the first scraper 61 and the transfer wheel 41. This ensures that the height of the first scraper 61 and the transfer wheel 41 is adapted to the position of the electrode sheet, facilitating the cleaning of unwanted electrode sheets.

[0031] Two cutters 31 and two connecting plates 32 are provided. The two cutters 31 are arranged opposite each other and are rotatably mounted on the two connecting plates 32 respectively.

[0034] More specifically, two rodless cylinders 21 are respectively mounted on two side plates 7, and each side plate 7 is provided with a slide rail 71. The stator of the linear motor 11 is slidably connected to the two slide rails 71 through two sliders 72. The slide rails 71 can guide the lifting and lowering of the linear motor 11, ensuring the accuracy of the lifting path of the linear motor 11.

[0035] A preferred embodiment of this utility model also provides an electrode cutting device, including a conveying mechanism and a transfer wheel cutting mechanism as described in the above embodiment. The conveying mechanism is located on the side close to the cutting blade assembly 3. The conveying mechanism is used to convey the electrode to the cutting blade 31. The cutting blade 31 cuts the electrode, and the unwanted electrode is transferred away by the transfer wheel 41. The horizontal and vertical movement of the cutting blade 31 and the transfer wheel 41 is controlled by the same set of translation drive 1 and lifting drive 2, which simplifies the structure of the device and reduces the production cost.
