[0033] Working principle: When in use, first place the PCB circuit board to be sprayed into the placement groove 4011. Since one side of the placement groove 4011 is an inclined structure, it is convenient to place and fix the PCB circuit board. At this time, the PCB circuit board will block the adsorption hole 4014, and then the piston plate 4012 can be pulled to move the piston plate 4012 along the negative pressure cavity 4013, so that negative pressure is formed between the piston plate 4012 and the PCB circuit board, and the PCB circuit board is adsorbed on the surface of the adsorption and fixing component 401, so that the PCB circuit board is unobstructed as a whole, so as to realize the adsorption and fixing function of the spray device on the PCB circuit board, thereby avoiding the phenomenon of spraying blind spots when the spray device is used.

While the spraying mechanism 2 is spraying the PCB circuit board, the staff can place the next group of PCB circuit boards to be sprayed on the surface of another adsorption and fixing mechanism 4, saving the time for placing the PCB circuit boards. At the same time, the paint can be blocked under the action of the baffle 3011 to realize the double-station spraying function of the spraying device, thereby improving the work efficiency when the spraying device is used.

[0035] Then, the control key 101 is operated to make the control key 101 control the nozzle 202 and the linear module 203 to operate. Under the action of the nozzle 202, the paint inside the coating box 201 is sprayed to the surface of the PCB circuit board, and under the action of the linear module 203, the nozzle 202 is driven to move the nozzle 202 up and down, and the PCB circuit board is sprayed as a whole to realize the spraying function of the spraying device on the PCB circuit board.

[0036] At this time, the paint dripping from the nozzle 202 falls into the interior of the fixed frame 503, and enters the collection frame 5021 after being filtered through the filter net 501 to collect the excess paint. At the same time, the control valve 5022 can be opened to discharge the paint inside the collection frame 5021 through the discharge pipe 5023 to realize the collection function of the dripping paint of the spray device, thereby avoiding the waste of paint when the spray device is used, and finally completing the use of the spray device.
