[0014] The present invention has the following beneficial effects: The present invention adds the spray paint into the interior of the storage tank, starts the water pump to transfer the paint to the interior of the bent pipe, and the paint inside the bent pipe enters the interior of the spray component to spray the PCB circuit board. After the PCB circuit board to be sprayed is inserted into the surface of the tapered rod, the PCB circuit board is pushed to the interior of the tapered rod by the inclination of the surface of the triangular slot plate when it moves downwardly to the tapered rod. When the PCB circuit board moves to the surface of the triangular slot plate, the triangular slot plate uses the elasticity of the elastic rod to squeeze and fix the PCB circuit board, thereby fixing the PCB circuit board to the surface of the tapered rod. The PCB circuit board is fixed by plugging, which improves the convenience of installing and removing the PCB circuit board. After the PCB circuit board is installed, the motor is started to drive the gear to rotate, and the gear drives the groove ring to be fixed by meshing with the groove ring. The top of the fixed ring rotates, and the fixed ring drives the tapered rod to rotate inside the circular groove frame through the connection between the round rod and the shaft rod when it rotates. The tapered rod pushes the PCB circuit board into the interior of the spray component for spraying. The shaft rod drives the engaging frame to rotate on the surface of the tooth ring as the groove ring rotates. The engaging frame drives the round rod to rotate inside the circular hole through engagement with the tooth ring as the groove ring rotates. The shaft rod drives the PCB circuit board to rotate as the round rod rotates. When the spray component sprays the PCB circuit board, the PCB circuit board is fully in contact with the paint through rotation, thereby improving the uniformity of spraying the PCB circuit board. When the shaft rod rotates inside the circular groove frame, it drives the scraper to rotate, and the waste paint entering the interior of the circular groove frame is scraped off by the scraper, and the waste paint is pushed into the interior of the circular tube by the scraper. The waste paint inside the circular tube will enter the interior of the storage rack for convenient centralized treatment.

[0015] After the curved pipe of the present invention transfers the paint to the interior of the connecting pipe, the paint will enter the interior of the rectangular tube, and the paint in the rectangular tube will be transferred to the interior of the spray rack through the positioning tube. The paint entering the interior of the spray rack is sprayed on the surface of the PCB circuit board through the nozzle. Nozzles are arranged on the upper and lower parts of the spray rack. When the PCB circuit board enters the interior of the spray rack, the upper and lower nozzles inside the spray rack will spray the PCB circuit board together, thereby spraying both sides of the PCB circuit board, thereby improving the convenience of spraying both sides of the PCB circuit board.

[0016] When the shaft rod of the present invention moves toward the inside of the arc frame, the through-hole extrusion plate on the surface of the shaft rod will contact the surface of the arc-shaped inclined plate and push the arc-shaped inclined plate to squeeze the elastic rod. When the arc-shaped inclined plate moves, it pushes the movable frame to move downward through the force-bearing plate. When the movable frame moves downward, it pushes the sliding frame to move downward through the stabilizing rod. The surface of the positioning tube is slidably connected to the inner wall of the connecting block, so that the positioning tube is used to limit the connecting block. At this time, when the sliding frame moves downward, it will push the spray frame to move toward the center of the arc frame through the inclined plate, so that the spray frame will wrap the PCB circuit board for spraying. The spray frame sprays the PCB circuit board during the movement, so that the spray frame can spray the PCB circuit board more comprehensively, thereby improving the spraying effect on the PCB circuit board.

[0017] When the movable frame of the present invention moves downward, the sealing plate is pushed downward by the connection between the linkage plate and the bent rod. When the through-hole extrusion plate is separated from the arc-shaped inclined plate, the arc-shaped inclined plate is reset by the elasticity of the elastic rod. When the arc-shaped inclined plate is reset, it pushes the movable frame to move upward. When the movable frame moves upward, the sealing plate is pushed upward by the bent rod. The blown air generated when the sealing plate moves upward enters the interior of the air outlet frame through the transmission pipe. The air outlet frame uses gas to clean the dust on the surface of the PCB circuit board, so as to prevent dust from adhering to the surface of the PCB circuit board and affecting the spraying effect.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the fixing ring 155 rotates, the conical rod 161 is driven to rotate inside the circular groove frame 1 through the connection between the round rod 153 and the shaft rod 154. When the conical rod 161 rotates, it pushes the PCB circuit board 9 into the interior of the spraying component 17 for spraying. When the shaft rod 154 rotates with the groove ring 151, it drives the engagement frame 156 to rotate on the surface of the toothed ring 157. When the groove ring 151 rotates, the engagement frame 156 will rotate with the toothed ring 157 The meshing drives the round rod 153 to rotate inside the round hole 152, and the shaft 154 drives the PCB circuit board 9 to rotate as the round rod 153 rotates. When the spraying component 17 sprays the PCB circuit board 9, the PCB circuit board 9 is fully in contact with the paint through rotation, thereby improving the uniformity of the spraying of the PCB circuit board 9. When the shaft 154 rotates inside the circular groove rack 1, it drives the scraper 158 to rotate, and the scraper 158 scrapes off the waste paint entering the circular groove rack 1, and pushes the waste paint into the inside of the circular tube 10 through the scraper 158. The waste paint inside the circular tube 10 will enter the inside of the storage rack 2 for its centralized treatment. After the elbow 13 transfers the paint to the inside of the connecting pipe 183, the paint will enter the inside of the rectangular tube 181. The rectangular tube 181 The paint in the spray rack 191 is transferred to the interior of the spray rack 191 through the positioning tube 193, and the paint entering the spray rack 191 is sprayed on the surface of the PCB circuit board 9 through the nozzle 192. The nozzles 192 are arranged on the upper and lower parts of the spray rack 191. When the PCB circuit board 9 enters the interior of the spray rack 191, the upper and lower nozzles 192 inside the spray rack 191 will spray the PCB circuit board 9 together, thereby spraying both sides of the PCB circuit board 9, improving the convenience of spraying both sides of the PCB circuit board 9. When the shaft 154 moves toward the interior of the arc frame 182, the through-hole extrusion plate 4 on the surface of the shaft 154 will contact the surface of the arc-shaped inclined plate 222, and push the arc-shaped inclined plate 222 to squeeze the elastic rod 221.When the arc-shaped inclined plate 222 moves, it pushes the moving frame 214 downward through the force plate 215. When the moving frame 214 moves downward, it pushes the sliding frame 212 downward through the stabilizing rod 213. The surface of the positioning tube 193 is slidably connected with the inner wall of the connecting block 194, so that the positioning tube 193 is used to limit the connecting block 194. At this time, when the sliding frame 212 moves downward, it pushes the spraying frame 191 toward the center of the arc frame 182 through the inclined plate 216, so that the spraying frame 191 will wrap the PCB circuit board 9 for spraying. The spraying frame 191 sprays the PCB circuit board 9 during the movement, so that the spraying frame 191 can spray the PCB circuit board 9 more comprehensively, thereby improving the PCB circuit board 9. To achieve the desired spraying effect on the PCB 9, when the movable frame 214 moves downward, the connection between the linkage plate 241 and the curved rod 242 pushes the sealing plate 244 downward. When the through-hole extrusion plate 4 separates from the curved inclined plate 222, the curved inclined plate 222 returns to its original position due to the elasticity of the elastic rod 221. When the curved inclined plate 222 returns to its original position, it pushes the movable frame 214 upward. When the movable frame 214 moves upward, the curved rod 242 pushes the sealing plate 244 upward. The air generated by the upward movement of the sealing plate 244 enters the interior of the air outlet frame 253 through the transmission pipe 252. The air outlet frame 253 uses air to clean dust from the surface of the PCB 9, preventing dust from adhering to the surface of the PCB 9 and affecting the spraying effect.
