It can be understood that the manipulator 4 can absorb the good lamp beads from the feeding mechanism 6 one by one and attach them to the LED lamp board.

[0030] In the present invention, the material transfer mechanism 1 transfers the LED light board to the rejection station, after the identifier 2 detects the defective lamp beads of the LED light board, the fusion welder 3 desolders the defective lamp beads on the LED light board, and the manipulator 4 removes the defective lamp beads on the LED light board and exposes the soldering pads on the LED light board; the material transfer mechanism 1 transports the LED light board to the tinning station, and the tinning mechanism 5 prints solder paste on the soldering pads on the LED light board; the material transfer mechanism 1 then transports the tinned LED light board to the mounting station, and the manipulator 4 is also used to absorb the good lamp beads on the feeding mechanism 6 and mount them on the soldering pads of the LED light board. In the present invention, the LED light board rework equipment can complete the automatic detection of the LED light board, the removal of defective lamp beads, the mounting of good lamp beads, etc., thereby improving the automation degree and rework efficiency of the LED light board rework equipment.

[0031] In one embodiment, if Figure 7 As shown, the feeding mechanism 6 includes a ejection component 61 and a flexible storage tray 6221 for storing good quality lamp beads; the ejection component 61 includes a first driving member 611, a second driving member 612, an ejector pin 613 and a top plate 614 provided with a suction hole 6141, the top plate 614 is installed at the output end of the first driving member 611, the second driving member 612 is installed on the top plate 614, and the ejector pin 613 is installed at the output end of the first driving member 611; it can be understood that the first driving member 611 and the second driving member 612 both include but are not limited to pneumatic cylinders, hydraulic cylinders and screw nut mechanisms; a plurality of good quality lamp beads are stored in the flexible storage tray 6221, and the bottom of the flexible storage tray 6221 is a flexible film; a plurality of suction holes 6141 are provided on the top plate 614.

[0039] The tinning mechanism 5 prints the solder paste on the pads of the LED light board on the support seat 13; the material transfer component 12 then transfers the LED light board on the support seat 13 to the support table 14, and the support table 14 drives the LED light board to the mounting station, and the manipulator 4 is also used to absorb the good lamp beads on the feeding mechanism 6 and mount them on the pads of the LED light board.
