Description

Technical Field

[0001] The present application relates to the field of battery pole piece cutting dies, and in particular to a battery pole piece cutting die with a quick-release cleaning mechanism. Background Art

[0002] In the battery manufacturing industry, the cutting of battery pole pieces is one of the key steps in the production process, and its quality directly affects the performance and safety of the battery. Traditional battery pole piece cutting molds usually consist of a mold frame, an upper cutting mold, and a lower cutting mold, and the precise cutting of the pole pieces is achieved through the closing action of the upper and lower molds. However, in the actual production process, the upper cutter of the upper cutting mold often accumulates impurities such as dust and metal debris after long-term use. These impurities not only affect the cutting accuracy and efficiency, but may also damage the mold and shorten its service life.

[0003] To solve this problem, the existing practice is usually for operators to manually clean the upper cutter when the mold is shut down for maintenance. This method is not only inefficient and increases the downtime of the production line, but also it is difficult to ensure the thoroughness and consistency of manual cleaning, which in turn affects product quality. In addition, frequent manual cleaning may also pose a potential threat to the safety of operators.

[0004] In order to overcome the above defects, some advanced battery electrode cutting dies have begun to introduce automatic cleaning mechanisms. These cleaning mechanisms usually use preset mechanical structures, such as cylinders, motors and other driving devices, to drive cleaning components (such as cleaning brushes, cleaning cloths, etc.) to wipe or purge the upper cutter to achieve automatic cleaning. However, most of the existing automatic cleaning mechanisms have problems such as complex structures and inconvenient maintenance. In particular, the cleaning components are easily worn and difficult to replace due to long-term contact with impurities such as metal debris, resulting in reduced cleaning effect and increased maintenance costs. Summary of the invention

[0011] In one embodiment, the cleaning brush further includes a lower cleaning portion, which is disposed at the lower portion of the cleaning brush. The lower cleaning portion is a silicone cleaning portion and is used to clean the lower cutting knife of the lower cutting die.

[0012] In one of the embodiments, the cleaning device further comprises a dust suction device, which is disposed on one side of the mold frame rail and corresponds to the cleaning brush and is used to clean dust on the cleaning brush.

[0028] Description of reference numerals: DETAILED DESCRIPTION

[0029] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the battery pole piece cutting mold of the quick-detachable cleaning mechanism in this embodiment is mainly composed of a mold frame 1, an upper cutting mold 2, a lower cutting mold 3 and a cleaning mechanism 4. The mold frame 1 serves as a supporting structure for the entire mold, and the upper cutting mold 2 and the lower cutting mold 3 are installed relatively up and down inside the mold frame 1 for accurately cutting the battery pole piece.

[0031] like Figure 2 As shown, the cleaning mechanism 4 is arranged on one side of the mold frame 1, and specifically, it comprises a transverse guide rail 41, a cleaning device 42 and a cleaning drive device 7. The transverse guide rail 41 extends in the transverse direction of the mold to provide a guide for the transverse movement of the cleaning device 42. The cleaning device 42 is mounted on the transverse guide rail 41 and can move smoothly in the transverse direction along the transverse guide rail 41.

[0032] like Figure 3 As shown, the cleaning device 42 is composed of a transverse sliding block 421, a transverse seat 422 and a cleaning portion 423. The transverse sliding block 421 cooperates with the transverse guide rail 41 to ensure that the cleaning device 42 can move accurately along the guide rail. The transverse seat 422 is installed on the transverse sliding block 421 as a supporting structure for the cleaning portion 423.

[0033] like Figure 4As shown, the cleaning part 423 is detachably mounted on the traverse seat 422. This design makes the replacement and maintenance of the cleaning part 423 extremely simple. In this embodiment, the cleaning part 423 includes a cleaning brush 4231 and a mounting seat 4232. The cleaning brush 4231 is mounted on the mounting seat 4232 and is a soft silicone brush. The soft silicone brush can effectively remove dust, metal debris and other impurities on the surface of the upper cutter of the upper cutting die 2 with its excellent wear resistance, elasticity and anti-fouling properties, while avoiding damage to the edge of the cutter.

[0034] like Figure 2 As shown, the cleaning drive device 7 can be a power source such as a motor or a cylinder, which is connected to the cleaning device 42 through a driving mechanism, thereby driving the cleaning device 42 to perform a lateral cleaning movement along the transverse guide rail 41. After the cutting die completes a cutting operation, the cleaning drive device 7 is started, driving the cleaning device 42 to move to the upper cutting knife position of the upper cutting die 2, and the silicone soft brush contacts the surface of the upper cutting knife to perform a cleaning operation. After the cleaning is completed, the cleaning drive device 7 is started again, driving the cleaning device 42 to return to the initial position, waiting for the next cleaning task.

[0035] When the silicone soft brush is severely worn or needs to be cleaned, the operator can easily remove it from the traverse seat 422, replace or clean it, and then reinstall it back to the traverse seat 422. The entire replacement process is quick and easy and does not require complex tools or skills.

[0036] Through the description of the above embodiments, it can be seen that the battery pole piece cutting mold with a quick-release cleaning mechanism of the present invention not only realizes the automatic cleaning of the cutter on the upper cutting mold, improves the cleaning efficiency and cleaning quality, but also simplifies the replacement and maintenance process of the cleaning parts through the quick-release design, reduces the maintenance cost, and improves the safety and convenience of the operator. At the same time, the use of a silicone soft brush further enhances the cleaning effect and durability, providing a strong guarantee for the long-term stable operation of the battery pole piece cutting mold.

[0037] like Figure 5 As shown, in this embodiment, the cleaning brush 4231 includes not only an upper cleaning portion 4231a, but also an additional lower cleaning portion 4231b. The design of the upper cleaning portion 4231a is particularly unique, and its brush teeth are arranged in a relative arrangement by first brush teeth 4231a1 and second brush teeth 4231a2. A brush groove 4231a3 is formed between the first brush teeth 4231a1 and the second brush teeth 4231a2. This design can more effectively capture and remove impurities on the surface of the cutter on the upper cutting die. The first brush teeth 4231a1 and the second brush teeth 4231a2 are evenly arranged in multiple pieces along the length direction of the cleaning brush 4231, and appropriate spacing is left between each brush tooth to ensure flexibility and adaptability during cleaning.

[0038] like Figure 5 As shown, in order to further protect the cutter, a first chamfer 4231a4 is provided on the side of the first brush tooth 4231a1 corresponding to the second brush tooth 4231a2, and a second chamfer 4231a5 is provided on the side of the second brush tooth 4231a2 corresponding to the first brush tooth 4231a1. This chamfer design makes the contact between the cleaning brush 4231 and the cutter softer, effectively avoiding any potential damage to the cutter caused by cleaning.

[0039] like Figure 5 As shown, in addition, a first avoidance portion 4231a6 is cleverly provided at the bottom of the first brush tooth 4231a1, and a second avoidance portion 4231a7 is provided at the bottom of the second brush tooth 4231a2. These avoidance portions provide necessary bending and deformation space for the upper part of the brush teeth, so that the cleaning brush 4231 can better adapt to the contour of the cutter during the cleaning process, thereby further improving the cleaning effect and protecting the cutter.

[0040] like Figure 4 As shown, the lower cleaning portion 4231b is arranged at the lower part of the cleaning brush 4231, and is made of silicone material, and is specifically used to clean the lower cutter of the lower cutting die. This design enables the cleaning mechanism of the present invention to clean the upper cutter and the lower cutter at the same time, greatly improving the cleaning efficiency and the convenience of mold maintenance.

[0041] like Figure 6 As shown, in order to more effectively clean the dust and impurities on the cleaning brush 4231, this embodiment also introduces a dust suction device 6. The dust suction device 6 is arranged on one side of the mold frame, corresponding to the cleaning brush 4231. The dust suction device 6 includes a dust suction seat 61 and a dust suction connector 62. The dust suction connector 62 is arranged on one side of the dust suction seat 61, which is convenient for connecting with an external dust suction device. A dust suction port 611 and a dust suction channel 612 are provided inside the dust suction seat 61. The dust suction port 611 corresponds to the cleaning brush 4231, ensuring that the dust and impurities on the brush can be sucked away in time during the cleaning process. The dust suction channel 612 connects the dust suction port 611 with the dust suction connector 62 to form a complete dust suction system.

[0042] like Figure 2 As shown, the cleaning drive device 7 in this embodiment adopts a more advanced driving method, including a driving motor 71, a driving wheel 72, a guide wheel 73 and a driving rope 74. The driving wheel 72 is mounted on the output shaft of the driving motor 71, one side of the driving rope 74 is wound around the driving wheel 72, and the other side is fixed to the guide wheel 73. The middle part of the driving rope 74 is connected to the traverse seat 422 to form a closed-loop driving system. When the driving motor 71 is started, the driving wheel 72 rotates, and the traverse seat 422 and the cleaning brush 4231 are driven by the driving rope 74 to perform lateral cleaning movement along the traverse guide rail 41. This driving method is not only compact in structure and stable in operation, but also easy to control and maintain.

[0043] like Figure 7 As shown, in order to further improve the efficiency of mold replacement and maintenance, this embodiment is further provided with a quick release device 8. The quick release device 8 includes a first quick release device 81 and a second quick release device 82, which are respectively used for the quick installation and removal of the upper cutting mold 2 and the lower cutting mold 3. The upper cutting mold 2 is installed on the upper support plate of the mold frame through the first quick release device 81, and the lower cutting mold 3 is installed on the lower mold base of the mold frame through the second quick release device 82. This quick release design makes the replacement and maintenance of the mold simpler and faster, greatly improving the flexibility and efficiency of the production line.

[0044] like Figure 7 As shown, the first quick-release device 81 includes a first quick-release seat 811 and a first quick-release column 812. The first quick-release seat 811 is provided with a first quick-release groove 8111, and the first quick-release column 812 is provided with a first quick-release head 8121. The upper cutting die 2 is mounted on the upper support plate through the first quick-release groove 8111 and the first quick-release head 8121.

[0045] like Figure 7 As shown, the second quick-release device 82 includes a second quick-release roller mounting seat 821, on which a quick-release roller 822 is provided. When the lower cutting die is fixed, the quick-release roller 822 is pressed against the inclined surfaces on both sides of the lower die bottom plate of the lower cutting die 3.
