[0049] like Figure 1 - Figure 4 As shown, the utility model provides an embodiment of an LED workpiece surface processing device.

[0050] The LED workpiece surface processing device comprises:

[0051] Surface component analyzer 5, analyzes the surface of LED workpiece and qualitatively determines the surface material of LED workpiece;

[0052] Laser 2, generating the laser light required for cleaning glue and melting solder at solder joints;

[0053] A contour scanning camera 6 detects in real time the scanning path of the laser to clean the glue;

[0054] The control module 9 is provided with at least one set of cleaning data of cleaning glue corresponding to the surface material.

[0055] Control the laser to perform cleaning according to the cleaning data corresponding to the surface material determined by the surface component analyzer and the scanning path determined by the profile scanning camera;

[0056] After the surface component analyzer qualitatively obtains the surface material, it controls the laser according to the cleaning data corresponding to the surface material, so that the laser cleans and scans the surface of the LED workpiece according to the path planned by the contour scanning camera.

[0057] Specifically, the laser 2 uses an ultraviolet laser with a wavelength of 355nm; the surface composition analyzer 5 uses existing technology and can obtain qualitative results and distribution status of the material in the area to be processed, as well as corresponding coordinate data, by analyzing the image features of the surface of the workpiece.

[0058] The control module 9 adopts existing technology, such as a single chip microcomputer, etc., and is preset with processing parameters adapted according to the characteristics of the material to be processed. For example, when the cleaning glue is A, the A1 processing parameter (cleaning data) is the best, and when the cleaning glue is B, the B1 processing parameter (cleaning data) is the best. The control module 9 contains processing parameters corresponding to such qualitative materials, and each processing parameter can be obtained through limited experiments or empirical data. The processing parameters include laser light frequency and scanning speed, etc.

[0059] The LED workpiece surface processing device also includes an optical path component 3 that transports the laser to the cleaning position, collects the LED workpiece surface image, and plans the scanning path. When the workpiece to be processed has different materials, when the laser scans the area, the control module 9 automatically calls the processing parameters that match the material in the area from the preset database, controls the laser to work, and thus obtains a better processing effect.

[0060] The optical path component 3 includes a first total reflection mirror 31 for total reflection of the laser light emitted by the laser 2; a second total reflection mirror 32 for total transmission of the laser light and total reflection of the optical path of the profile scanning camera 6 and the surface component analyzer 5; a third total reflection mirror 33 for total reflection of the optical path of the laser 2, the profile scanning camera 6 and the surface component analyzer 5; and a galvanometer 5 for guiding the laser, the profile scanning camera and the surface component analyzer 5 to the cleaning position (cleaning position) of the LED workpiece surface and the laser scanning speed. Due to such an optical path component, part of the optical path can be shared, saving the number of parts and components and the difficulty of assembly.

[0061] The LED workpiece surface processing device further includes a positioning camera 4 which is connected to the control module 9 by signals to determine the position of the LED workpiece.

[0062] When in use, the workpiece (such as an LED workpiece) can be placed on the operating table 10 and fixed by a vacuum adsorption mechanism (not shown in the figure); after the positioning camera 4 determines the position of the LED workpiece, the control module 9 controls the surface component analyzer 5 to collect the LED workpiece image on the operating table 10 through the optical path component 3, and determines the surface material of the LED workpiece and the distribution area of ​​different materials according to the image features. Then, the control module 9 controls the laser to perform processing according to the processing parameters matching the surface material of the corresponding position of the determined LED workpiece. At the same time, the image of the processing position is scanned in real time by the contour scanning camera 6, and the laser processing path is guided in real time, so that the image of the processing position matches the preset data, that is, the contour after processing matches the contour image that needs to be achieved in theory. When the material of another processing area is different from that of the previous processing area, the control module 9 controls the laser to process the area according to the processing parameters corresponding to the area, so that each processing area is processed with the best processing technology, which not only improves the processing accuracy, but also reduces the impact on the non-processing area. Automatic processing can be fully realized and processing efficiency can be improved.

The smoke extraction mechanism 8 includes a smoke hood 81 and an exhaust duct 82 connected to the smoke hood 81, and an exhaust fan connected to the exhaust duct 82 (not shown in the drawings).

[0064] According to the needs, the LED workpiece surface processing device also includes a three-dimensional moving mechanism that enables the laser 2, the contour scanning camera 6, the positioning camera 4 and the optical path component 3 to move in the X, Y, and Z coordinate systems. The three-dimensional moving mechanism includes an X-axis translation servo component and an X-axis translation servo component, and a Z-axis movement servo component 7. The X-axis translation servo component and the X-axis translation servo component, and the Z-axis movement servo component 7 can be implemented using existing technologies and will not be described in detail. In this embodiment, the LED workpiece surface processing includes LED workpiece surface cleaning.
