When the transmittance of the LED lamp beads is changed, firstly, the LED lamp panels to be treated are placed on the conveyor belt 101, then the conveyor belt 101 is started, the LED lamp panels are conveyed between the piston rods 302 through the conveyor belt 101, then the high-pressure air pump 201 is started, external air is sucked through the high-pressure air pump 201 and discharged into the piston cylinder 301 through the air outlet pipe 202, at the moment, the air pressure in the piston cylinder 301 is increased, the piston rods 302 are moved under the influence of the air pressure, further, the two groups of the piston rods 302 move towards the LED lamp panels until the two groups of the piston rods are in contact with the LED lamp panels, the clamping effect is achieved, then the control valve is opened, the air in the piston cylinder 301 is discharged through the air outlet holes 303, at the moment, the air in the piston cylinder 301 enters the outer connecting pipe 401 through the air outlet holes 303, the rotating cover 402 is rotated through the air flow, and redundant air is discharged through the air outlet 4021 (the air outlet holes 4021 are satisfied, and can not excessively discharge, reduce the possibility of influencing the clamping effect), blow the surface of the LED lamp panel, meanwhile, because of the arrangement of the rotation cover 402, the blown gas range is wider, the lamp beads on the LED lamp panel can be effectively radiated, then the ultraviolet nanosecond laser head 1035 is started, the lamp beads are roughened through the ultraviolet nanosecond laser head 1035, the ultraviolet nanosecond laser head 1035 is adopted, because the wavelength is short, the photon energy is strong, the smaller influence can be generated, the effect is relatively better, at the moment, with the use of the ultraviolet nanosecond laser head 1035, the lamp beads of the LED lamp panel are roughened one by one, the transmittance is relatively consistent, after the lamp beads on the LED lamp panel are roughened, the high-pressure air pump 201 is turned off, the piston cylinder 301 is reset under the action of the built-in spring, and then the conveyor belt 101 is started again, the LED lamp panels after roughening are transported through the conveyor belt 101 until coming to the lower part of the detection camera 1041, the LED lamp panels after roughening are detected through the detection camera 1041, whether the lamp beads which are not roughened exist or not are checked, or the lamp beads Bei Maohua are excessive and damaged, if the lamp beads are damaged, then the telescopic rod 1042 is started, the LED lamp panels are pushed away through the push plate 1043 to come into the collecting box 105, the LED lamp panels are recovered through the collecting box 105, the subsequent reprocessing is convenient, if normal, the conveyor belt 101 continues to operate, and when the LED lamp panels are detected, the front ultraviolet nanosecond laser head 1035 can carry out roughening treatment on the LED lamp panels, so that the use is convenient.
According to the invention, the surface of the LED lamp bead is roughened by adopting laser generated by the ultraviolet nanosecond laser head 1035, namely, the condition of different original initial roughness can be corrected in the mode, and after the laser acts, the whole LED lamp bead is adjusted to the same roughness, so that the basically consistent light transmittance is achieved, the display difference is eliminated, and the whole display breadth can show more consistent display effect.
The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
