The circuit board A faces upwards and is placed on an empty jig positioned and stopped on the upper plate device 11, then a release button is pressed, the upper plate conveying rail 112 conveys the jig carrying the circuit board to the front lifting device 12, the conveying process is performed through the upper plate discharging sensor 116, the first feeding sensor 124 and the first discharging sensor 126, the starting and stopping of the upper plate conveying rail 112 and the front conveying rail 123 are controlled through sensing signals, the rear front lifting device 12 stops conveying when the jig is sensed by the first discharging sensor 126, the front lifting device 12 conveys the jig to the first board passing device 1B after the first board passing device 1B gives a signal needing to be fed, and the front lifting device 12 conveys the jig to the spraying device 13 after the spraying device 13 gives a signal needing to be fed.

Each time the subsequent jig is conveyed from one device to another, the corresponding sensor senses the jig, the conveying position is fed back, and the sensing is not described in detail later.

After the jig enters the spraying device 13, the spraying information reading mechanism 13A reads the information code on the circuit board, then software of the spraying device 13 can call up the current spraying track program of the circuit board, and the spraying operation is performed by controlling the movement of the spray head 139.

After spraying, the jig is conveyed to the second board passing connection device 1C, after the curing device 14 gives a signal for feeding, the jig enters the curing device 14, the coating on the circuit board is gradually cured through ultraviolet irradiation, and after curing, the jig is conveyed to the board turning device 15.

After the jig enters the set position of the plate turnover device 15, the conveying is stopped, the plate turnover information reading mechanism can read the information code on the circuit board to confirm whether the circuit board needs to be turned over or not, if the circuit board is the circuit board with both sides needing spraying and dispensing operation, the circuit board is the surface A, and therefore the circuit board needs to be turned over to the surface B upwards. The cylinder 1571 drives the first limiting block 1573 and the second limiting block 1521 to avoid the position, then the overturning motor 158 controls the fixing plate 152 to rotate, so that the jig overturns 180 degrees, and after overturning, the cylinder 1571 drives the first limiting block 1573 to contact with the second limiting block 1521, so that the fixing plate 152 is kept stable. And then the conveying track is turned over to convey the jig to the third board passing and connecting device 1D.

After the dispensing device 16 gives a signal that needs to be fed, the third board passing connection device 1D conveys the jig to the dispensing device 16, and stops after conveying to the dispensing position, the dispensing information reading mechanism 161 can read the information code on the circuit board, and software of the dispensing device 16 can call out a dispensing track program of the current circuit board immediately, and dispensing operation is performed by controlling movement of the dispensing head.
