Description

Technical Field

[0043] To address the problem in related technologies where the laser device 2 cannot accurately clean the preset cleaning position of the electrode 9 due to the electrode 9 lifting up when using a laser to clean the electrode 9, this utility model provides a laser cleaning device for electrodes.

[0044] The laser cleaning device for electrodes according to this embodiment of the present invention includes a cleaning table 1, a laser device 2, a pressure plate 3, and a driving component 8. The cleaning table 1 has a vacuum adsorption hole 101 to adsorb the electrode 9 onto the cleaning table 1; the laser device 2 is adapted to emit laser to clean the electrode 9; the driving end of the driving component 8 is connected to the pressure plate 3 to drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1.

[0045] The laser cleaning device for electrodes in this embodiment of the present invention includes a pressure plate 3 and a driving component 8 that can drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1. The driving component 8 can drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1, which can prevent the electrode 9 from warping. As a result, the preset cleaning position on the electrode 9 can accurately coincide with the preset cleaning position of the laser device 2, that is, the laser device 2 can accurately clean the preset cleaning position on the electrode 9.

[0046] The following is in conjunction with the appendix Figure 1-3 The laser cleaning apparatus for electrodes according to an embodiment of this utility model will be further described below.

[0047] like Figure 1As shown, the laser cleaning device for electrodes in this embodiment of the present invention includes a cleaning table 1, a laser device 2, a pressure plate 3, and a driving component 8.

[0048] As shown in the figure, the electrode 9 passes over the upper surface of the cleaning table 1. The cleaning table 1 has a vacuum adsorption hole 101. The air inlet of the vacuum adsorption hole 101 is located on the upper surface of the cleaning table 1 to adsorb the electrode 9 located on the upper surface of the cleaning table 1 onto the cleaning table 1. The air outlet of the vacuum adsorption hole 101 is located on the lower surface of the cleaning table 1 to facilitate connection to the vacuum generator 10. The laser device 2 is located above the cleaning table 1 and is adapted to emit laser to clean the electrode 9. The driving end of the driving member 8 is connected to the pressure plate 3 to drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1, which can prevent the electrode 9 from warping.

[0049] It is understandable that the driving component 8 can drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1, and at the same time, it can also drive the pressure plate 3 to separate from the electrode 9 and the cleaning table 1. That is, the driving component 8 can drive the pressure plate 3 to move in the up and down direction.

[0050] The laser cleaning device for electrodes in this embodiment of the present invention, by setting a pressure plate 3 and a driving component 8 that can drive the pressure plate 3 to press the electrode 9 onto the cleaning table 1, can avoid the problem of the electrode 9 lifting up. Thus, the preset cleaning position on the electrode 9 can accurately coincide with the preset cleaning position of the laser device 2, that is, the laser device 2 can accurately clean the preset cleaning position on the electrode 9.

[0051] In some embodiments, as shown in the figure, the pressure plate 3 includes a fixing part 301 and a pressing part 302. One end of the pressing part 302 is connected to the fixing part 301. The fixing part 301 is connected to the driving end of the driving member 8. The pressing part 302 is used to press the electrode 9 onto the cleaning table 1, which can prevent the electrode 9 from warping. Thus, the preset cleaning position on the electrode 9 can accurately coincide with the preset cleaning position of the laser device 2, that is, the laser device 2 can accurately clean the preset cleaning position on the electrode 9.

[0052] In some embodiments, the laser cleaning device for electrodes of this utility model further includes an adjustment plate 4, which is disposed at the driving end of the driving member 8. The adjustment plate 4 is provided with a first hole 5 and the fixing part is provided with a second hole 6.

[0053] Furthermore, at least one of the first hole 5 and the second hole 6 is provided as a plurality and distributed at intervals along the length direction of the electrode 9; or,

[0054] At least one of the first hole 5 and the second hole 6 is configured as an oblong hole and extends along the length direction of the electrode 9; or

[0055] One of the first hole 5 and the second hole 6 is configured as multiple holes and distributed at intervals along the length direction of the electrode 9, while the other is configured as a waist-shaped hole and extends along the length direction of the electrode 9.

[0061] The first hole 5 is configured as an oblong hole and extends along the length of the electrode 9; the second hole 6 is configured as multiple holes and is distributed at intervals along the length of the electrode 9.

[0062] The first hole 5 is set as an oblong hole and extends along the length of the electrode 9; the second hole 6 is set as a single hole;

[0063] The first hole 5 is configured as an oblong hole and extends along the length of the electrode 9; the second hole 6 is configured as an oblong hole and extends along the length of the electrode 9.

[0064] The first hole 5 is a single hole; the second hole 6 is a waist-shaped hole that extends along the length of the electrode 9.

[0066] By setting the first hole 5 and the second hole 6 to the above structure, the relative position between the pressure plate 3 and the adjustment plate 4 can be adjusted, that is, the position of the pressure plate 3 pressed onto the electrode 9 can be adjusted, which facilitates adjustment according to actual cleaning needs.

[0067] In some embodiments, the pressing portion 302 extends along the width direction of the electrode 9, and the width direction of the electrode 9 and the length direction of the electrode 9 are perpendicular to each other.

[0068] In some embodiments, the pressing part 302 includes a single pressing strip 3021, one end of which is connected to the fixing part 301.

[0069] Furthermore, one end of a single pressure strip 3021 can be connected to either end of the fixing part 301 along the length of the electrode sheet.

[0070] Furthermore, such as Figure 3 As shown, there are two pressure plates 3, which are spaced apart along the length of the electrode 9.

[0071] As mentioned above, by setting the first hole 5 and the second hole 6 to the above structure, the relative position between the pressure plate 3 and the adjustment plate 4 can be adjusted, that is, the distance between the pressure strips 3021 of the two pressure plates 3 can be adjusted, and thus can be adjusted according to the actual cleaning needs.

[0072] In some embodiments, the pressing part 302 includes two pressing strips 3021, one end of which is connected to the fixing part 301, and the two pressing strips 3021 are spaced apart in the length direction of the electrode 9 so that the laser emitted by the laser device 2 can pass through.

[0073] Furthermore, the pressure plate 3 also includes a connecting strip 3022, the two ends of which are respectively connected to the other ends of the two pressure strips 3021.

[0074] In some embodiments, the pressing part 302 of the present invention further includes a connecting bracket 7, which includes a first connecting part 701 and a second connecting part 702 connected together. The first connecting part 701 is connected to the cleaning table 1, and the second connecting part 702 is connected to the driving member 8.

[0075] Furthermore, the first connecting part 701 and the second connecting part 702 are perpendicular to each other. The first connecting part 701 is horizontally arranged and connected to the lower surface of the cleaning table 1, while the second connecting part 702 is vertically arranged and spaced apart from the front side of the cleaning table 1.

The cylinder body of the telescopic cylinder is connected to the second connecting part 702, and the driving end of the telescopic cylinder is connected to the adjusting plate 4 to drive the adjusting plate 4 and the pressure plate 3 to move in the vertical direction, thereby achieving the effect of pressing the electrode 9 onto the upper surface of the cleaning table 1.
