[0027] Reference Figs. 1 to 3 A pole piece cutting device, comprising: a cutting cavity 1, a laser cutting mechanism, a dust collection mechanism 3 and a spacing adjusting mechanism 4;

[0028] The laser cutting mechanism is arranged on one side of the cutting cavity 1, and a through groove 11 for laser passing through is arranged on the cutting cavity 1;

[0029] An opening 12 is arranged on one side of the cutting cavity 1, the dust collection mechanism 3 is arranged on the side of the opening 12, and the dust suction port 35 of the dust collection mechanism 3 is arranged towards the opening 12;

[0030] One end of the spacing adjusting mechanism 4 is fixed on the outer wall of the cutting cavity 1, and the other end is slidably connected with the dust collection mechanism 3, and the dust collection mechanism 3 is used to adsorb dust in the cutting cavity 1.

[0031] The dust suction port 35 of the dust collection mechanism 3 is arranged towards the opening 12 of the cutting cavity 1, which can adsorb the dust escaping from the opening 12 and the dust in the cutting cavity 1 in time during the cutting process, can not only avoid the accumulation of dust in the cutting cavity, keep the pole piece clean, reduce the interference of dust on the cutting process, improve the cutting quality, but also can effectively prevent the dust from spreading to the working environment, reduce the harm to the health of the operator, and keep the working area clean.

[0032] In one embodiment, the spacing adjusting mechanism 4 comprises a sliding rail 41 and a sliding block 42; one end of the sliding rail 41 is connected with the cutting cavity 1, and the dust collection mechanism 3 is connected with the sliding block 42.

[0033] The sliding rail 41 is fixed in position with the cutting cavity 1, provides a stable moving platform for the dust collection mechanism 3, provides accurate guidance for the movement of the dust collection mechanism 3, and the cooperation of the sliding rail 41 and the sliding block 42 can ensure that the dust collection mechanism 3 always keeps stable during the movement, avoids affecting the dust collection effect due to shaking or deviation.

[0034] Specifically, the slide rail 41 is a linear guide rail.

[0035] Further, the dust suction mechanism 3 comprises a dust suction pipe assembly 31 and a filter screen 32, the dust suction port 35 is arranged on the dust suction pipe assembly 31, and the filter screen 32 covers the dust suction port 35. The filter screen 32 can prevent large objects from entering the dust suction pipe assembly 31 and prevent the dust suction pipe assembly 31 from being blocked.

[0036] Specifically, the connection mode of the filter screen 32 and the dust suction pipe assembly 31 is buckle connection, clamp connection or magnetic attraction connection.

[0037] Specifically, the dust suction pipe assembly 31 is provided with an anemometer 314, which facilitates real-time monitoring and adjustment of wind speed to avoid affecting the stability of the pole piece material belt cutting.

[0038] It can be understood that the dust suction mechanism 3 is signal connected with the wind speed control assembly, the anemometer 314 monitors the wind speed of the dust suction mechanism 3 in real time and feeds back data to the wind speed control assembly, and the wind speed control assembly adjusts the wind speed in real time and accurately controls the wind speed, so as to ensure the cutting quality.

[0039] More specifically, the dust suction pipe assembly 31 comprises a cover body 311 and a dust suction pipe 312, the dust suction port 35 is located on the cover body 311, and the dust suction pipe 312 is connected with the side of the cover body 311 away from the cutting cavity 1. The cover body 311 is arranged on the opening 12, which can relatively close the area where dust is generated, reduce the possibility of dust spreading to the outside, help to reduce the overflow of dust from the opening 12, and reduce environmental pollution.

[0040] More specifically, the dust suction pipe 312 is connected to the middle part of the cover body 311. This can make the dust suction port 35 form a more uniform negative pressure distribution in the cover body 311, ensure that the dust can be effectively sucked in all directions in the cover body 311, avoid the dead angle of dust suction caused by improper position of the dust suction port 35, and make the center of gravity of the dust suction assembly 31 more balanced in the process of moving the dust suction assembly 31, which helps to reduce the shaking or instability caused by improper position of the dust suction pipe 312, and ensures that the dust suction assembly 31 always remains stable during operation.

[0041] More specifically, the dust suction pipe assembly 31 is provided with a window 313, which is used to observe the flow direction of dust and whether large pieces of waste are adsorbed on the filter screen 32.

[0042] Specifically, the window 313 is a transparent piece, such as transparent glass, transparent acrylic plate, etc.

[0043] More specifically, the windows 313 are multiple, and are distributed on the cover 311 along the circumference of the dust suction pipe 312. When the observer is at a certain position, the flow of dust and the cutting of the pole piece can be observed.

[0044] Specifically, the dust suction mechanism 3 further comprises a support plate 33 and a sealing block 34, the slide rail 41 is fixed on the support plate 33, and the sealing block 34 is fixed at the end of the slide rail 41. The support plate 33 is used to fix the slide rail 41, and the sealing block 34 is used to limit the maximum distance between the dust suction pipe assembly 31 and the cutting cavity 1.

[0045] In an embodiment, a fixing assembly detachably connected with the cutting cavity 1 and the dust suction mechanism 3 is further included, and the fixing assembly is used to fix the dust suction mechanism 3 on the cutting cavity 1.

[0046] During the working process of the dust suction mechanism 3, negative pressure is generated, which may cause the dust suction mechanism 3 to shake, thereby causing the misalignment between the opening 12 and the dust suction port 35, and the overflow of dust from the misaligned gap. Therefore, the fixing assembly is arranged to fix the positions of the cutting cavity 1 and the dust suction mechanism 3, which can solve the above technical problems.

[0047] As an example, the fixing assembly is a conventional component such as a bolt, a magnet, or a buckle.
