The glue dispensing part 105 performs dot spraying glue on the concave part of the PCB board, and at the same time, the heat generated by the electromagnetic heater 107 quickly solidifies the dot spraying glue. Then, the leveling part 106 levels the dot spraying glue and clears the debris generated by the brushing, so as to realize the automated assembly line operation of the glue sealing and repair process of the PCB board.

Then, the leveling part 106 levels the dot spraying glue and cleans the debris generated by the brushing. The infrared generator in the infrared graphics part 206 generates infrared rays, which are emitted to the PCB board through the lens tube 207. The micro camera component in the infrared graphics part 206 draws a graph of the reflected infrared rays, so as to determine whether there are concavities and convexities on the corresponding PCB board below. Thus, the central control module 203 issues commands to schedule the start, stop and stroke of each electronic device. The servo motor 301 is started, and the rotating roller shaft 303 is driven to rotate synchronously in the bearing seat 304 through the bevel gear 302 group, so as to drive the connecting plate 104 to move vertically with a small amplitude, so that the dispensing part 105 and the leveling part 106 can be distributed for use to perform precise positioning repair operations.
