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

After the jig enters the coating device 13, the spraying information reading mechanism 13A reads the information code on the circuit board, and then the software of the coating device 13 immediately calls the current spraying track program of the circuit board, and executes the spraying operation by controlling the movement of the spray head 139.

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

The jig stops conveying after entering the set position of the plate turnover device 15, the plate turnover information reading mechanism reads the information code on the circuit board to determine whether to overturn, if the circuit board is a circuit board with both sides needing spraying and dispensing operation, the circuit board is the A side of the circuit board, and therefore the circuit board needs to be overturned to the B side upwards. Therefore, the plate turnover device 15 drives the turnover conveying rail to turn over, so that the jig is turned over by 180 degrees, and then the turnover conveying rail conveys the jig to the third plate passing connection device 1D.

After the dispensing device 16 sends a signal that feeding is required, the third board-passing docking device 1D conveys the jig to the dispensing device 16, and stops after conveying to the dispensing position, the dispensing information reading mechanism 161 reads the information code on the circuit board, and the software of the dispensing device 16 immediately calls out the dispensing trajectory program of the current circuit board, and performs dispensing operation by controlling the dispensing head to move. After dispensing, the jig is transported to the inspection device 17.

The jig enters the set position of the inspection device 17 and stops, the inspection information reading mechanism 171 can read the information code on the circuit board, the inspection software of the inspection device 17 immediately calls out a corresponding spraying effect inspection track program, the detection camera is controlled to execute the spraying and dispensing effect inspection track program for shooting and detecting, if the inspection is not qualified, the warning is given, and if the inspection is qualified, the jig is conveyed to the rear lifting device 18.

The jig stops after reaching the set position on the rear lifting device 18, the spraying detection mechanism 184 detects whether the surface B of the circuit board is sprayed with the coating, and since the surface a of the circuit board is sprayed before and the circuit board is turned over, the coating cannot be detected, the rear lifting mechanism 182 drives the rear conveying rail 183 to descend and butt with the return conveyor line body 1A, so that the jig is conveyed to the return conveyor line body 1A.

Then, the return conveyor line body 1A conveys the jig to the front lifting device 12, and when the jig is sensed by the return sensor at the end of the return conveyor line body 1A close to the front lifting device 12, the conveyance of the jig is stopped, and the control device controls the front lifting mechanism 122 to drive the front conveying rail 123 to descend and receive the jig on the return conveyor line body 1A. The jig stops after reaching the set position of the front conveying rail 123, and the front lifting empty jig detection mechanism 125 detects whether the jig carries a circuit board, if so, the front conveying rail 123 lifts and then conveys the jig to the first board passing connection device 1B, and if not, the front conveying rail 123 lifts and then conveys the jig to the board mounting device 11. The front conveying rail 123 receives the jig carrying the circuit board with the B-side facing upward, and thus conveys the jig to the first board passing apparatus 1B.

The circuit board with the B-side facing upwards is sprayed through the coating device 13, cured through the curing device 14, flipped through the flipping device 15, dispensed through the dispensing device 16, and inspected through the inspection device 17 as described above. If the surface A does not need dispensing, the turning and dispensing operation can be omitted according to the actual situation. When the circuit board reaches the set position on the rear lifting device 18, the circuit board stops (if the circuit board is turned over to make the surface a face upward), the spraying detection mechanism 184 detects that the surface a of the circuit board is sprayed with the coating, and therefore, the rear lifting device 18 conveys the jig to the lower board device 19. The jig is stopped after being sensed by the third discharging sensor 195, the circuit board can be manually removed, then the release button is pressed, the empty jig detecting mechanism 193 detects that the jig is empty, and the rear conveying rail 183 is butted with the rear lifting device 18 and receives the empty jig.

The rear lifting mechanism 182 drives the rear conveying rail 183 to descend to abut against the return conveyor line body 1A, the return conveyor line body 1A conveys the empty jigs to the front lifting device 12, and the front lifting device 12 conveys and receives the empty jigs and conveys the empty jigs to the upper plate device 11 after ascending. The empty jig is transported to the upper board positioning sensor 114 and stopped, and at this time, the unprocessed circuit board a may be placed on the empty jig on the upper board apparatus 11 with its surface facing upward. The processing operation is performed cyclically as described above.

This completes the processing of the coating apparatus of the preferred embodiment.

The coating equipment of the preferred embodiment can pass back the empty jig and the turned-over circuit board through the front lifting device, the rear lifting device and the pass-back conveying line body, and is high in automation degree and work efficiency. And the quality inspection of spraying and glue dispensing can be automatically carried out, the labor cost is saved, and the product quality is improved.

When the coating equipment conveys the jig, the extrusion block on the jig extrudes the compression block to move upwards, so that the sliding plate is driven to slide upwards, the second magnet absorbs all the first magnets, the sealing curtain single bodies can be stably butted and arranged, the sealing curtain is sealed to the opening, and the sealing effect is good.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.
