[0033] The spraying blocking mechanism 21 includes a bracket 216. The bracket 216 is fixedly connected to both ends of the top of the fixed plate 1. The top of the bracket 216 is fixedly connected with an X-axis assembly 211. A Y-axis assembly 212 is slidably connected to the surface of the X-axis assembly 211.

A transmission driving assembly 2171 is arranged on the surface of the belt assembly 217. Track sliders 218 are respectively fixedly connected to the front and rear ends of the top of the fixed plate 1. A width-adjusting lead screw 219 is arranged on the surface of the track slider 218. The top right end of the back of the belt assembly 217 is fixedly connected with a first blocking assembly 2172. There are two brackets 216, and the surfaces of the two brackets 216 are fixedly connected to the left and right ends of the top of the fixed plate 1. The fixing mechanism 22 includes a lower cover plate 224. The lower cover plate 224 is arranged on the top of the fixed plate 1. Elastic components 223 are respectively threadedly connected to the four corners inside the lower cover plate 224. A PCBA product 222 is arranged on the top of the lower cover plate 224. An upper cover plate 221 is arranged on the top of the PCBA product 222.

[0034] Further, round holes are respectively opened at the four corners of the upper cover plate 221 and the four corners of the lower cover plate 224. The surface of the elastic component 223 matches the inside of the round hole. When the product enters the first coating machine device 2, the photoelectric sensor detects the signal of the arrival of the product and feeds it back to the PLC. The PLC controls the upper transmission component 33 and the lower transmission component 34 to start transmitting the product. When the product reaches the spraying area, the photoelectric sensor in the spraying area detects the position of the product and feeds it back to the PLC. The PLC controls the second blocking component 35 to block the product, so that the product stops in the area to be sprayed. The nozzle assembly 213 realizes the spraying of the A surface of the product. After the spraying is completed, the blocking cylinder on the second blocking component 35 is controlled to reset, and the product enters the turning machine area.

[0035] Embodiment 2

[0036] Refer to Figures 1-8 and on the basis of Embodiment 1, it is further obtained that the turning machine device 3 includes a first turning driving component 31.

The upper transmission component 33 is distributed between the first turning driving component 31 and the second turning driving component 32. The lower transmission component 34 is distributed between the first turning driving component 31 and the second turning driving component 32.

[0037] Further, there are two sets of X-axis components 211 and Y-axis components 212. The two sets of X-axis components 211 and Y-axis components 212 are respectively arranged on the left and right sides of the first flipping drive component 31. Drive the second flipping drive component 32 to rotate 180 degrees to achieve product flipping, that is, the B side of the product faces upward. Finally, control the blocking cylinder to move upward and drive the upper conveying component 33 to rotate, so that the product is conveyed to the area of the second coating machine device 2. Similarly, the second coating machine device 2 sprays the B side of the product.

[0038] In the actual operation process, when this device is used, the surface coating process is the core of the PCBA double-sided automatic three-proof paint coating technology. When in use, place the product into the hole in the spraying area, cooperate with the positioning holes of the lower cover plate 224 and the upper cover plate 221, cover the upper cover plate 221, and fix the upper cover plate 221 and the lower cover plate 224 together. When the product enters the first coating machine device 2, the photoelectric sensor detects the signal of the product's arrival and feeds it back to the PLC. The PLC controls the upper conveying component 33 and the lower conveying component 34 to start conveying the product. When the product reaches the spraying area, the photoelectric sensor in the spraying area detects the product position and feeds it back to the PLC. The PLC controls the second blocking component 35 to block the product, so that the product stops in the area to be sprayed. The nozzle component 213 sprays the A side of the product. After spraying is completed, control the blocking cylinder on the second blocking component 35 to reset, and the product enters the flipping machine area;

[0039] The flipping machine device 3 detects the product and controls the lower conveying component 34 to rotate. The product continues to move forward. When the product is conveyed to the end, the blocking photoelectric sensor on the second blocking component 35 detects the product position and feeds it back to the PLC. The PLC controls the lower conveying component 34 to stop rotating, and at the same time controls the blocking cylinder on the second blocking component 35 to drive the blocking piece to move downward to block the product. Then, drive the second flipping drive component 32 to rotate 180 degrees to achieve product flipping, that is, the B side of the product faces upward. Finally, control the blocking cylinder to move upward and drive the upper conveying component 33 to rotate, so that the product is conveyed to the area of the second coating machine device 2. Similarly, the second coating machine device 2 sprays the B side of the product.
