[0038] The term "plurality" used in the present application refers to two or more (including two).

[0039] The following is combined with Figures 1 to 3 The utility model is further described in detail with specific implementation modes, but is not intended to limit the utility model.

[0040] A base plate structure for pole piece laser cleaning, comprising:

[0041] A fixing block 1, wherein the fixing block 1 is provided with a mounting groove 11;

[0042] A replaceable plate 2, the replaceable plate 2 matches the mounting groove 11 and the replaceable plate 2 is installed in the mounting groove 11, and the replaceable plate 2 is an axisymmetric structure;

The mounting groove 11 includes an opening 111 and recessed openings 112 located on both sides of the opening 111. The opening 111 is used to accommodate the plate body 21, and the recessed opening 112 is a semi-enclosed structure for accommodating the protruding blocks 22.

[0044] In actual applications, when the pole piece is laser cleaned, some areas of the bottom plate in the cleaning device will also be irradiated by the laser and easily damaged. In this embodiment, the replaceable plate 2 can be pulled out and inserted into the mounting groove 11, avoiding the need to remove the entire base for bottom plate replacement. This is convenient and practical, and there is no need to readjust the position of the base and the laser emitting device, thereby ensuring the consistency of the pole piece cleaning.

In practical applications, Figure 3 As shown, the pole piece 100 to be cleaned has a laser cleaning area 200, and the replaceable plate 2 has a laser irradiation area 300 arranged corresponding to the laser cleaning area 200. After the laser irradiation area 300 in a part of the replaceable plate 2 is damaged by the laser, it can be rotated and the other part can continue to be used, so as to maximize the use area of ​​the replaceable plate, increase its service life, and thus reduce the cost.

[0047] In actual applications, the two connecting holes 26 are respectively connected to the external pressure extraction device and the handle 3, so that the negative pressure adsorption force of the negative pressure chamber acts on the electrode 100 to be cleaned through the negative pressure hole 24, fixes the electrode 100 to be cleaned, and prevents it from being displaced during the cleaning process, which leads to a decrease in accuracy. The evenly distributed negative pressure holes 24 make the negative pressure adsorption force of the electrode 100 to be cleaned evenly dispersed, thereby making the surface of the electrode 100 to be cleaned smooth, further improving the accuracy of electrode cleaning.

[0048] Specifically, a shallow groove 27 is provided on the bearing surface 23. There are two shallow grooves 27. The two shallow grooves 27 are arranged close to the connecting hole 26. The shallow grooves 27 can be used to position the electrode 100 to be cleaned, and the shallow grooves 27 can facilitate the extraction of the replaceable plate 2.

[0049] Specifically, the handle 3 includes a handle body 31 and a connecting piece 32 connected to the handle body 31, the connecting piece 32 matches the connecting hole 26, the handle body 31 is configured as a curved cylindrical structure, the cross-sectional radius of the middle part of the handle body 31 is smaller than the cross-sectional radius at both ends of the handle body 31, and the curved cylindrical structure is convenient for the operator to use and avoids slipping or soreness of the hands.
