Two reverse-threaded lead screws are rotatably connected to the surface of the side plates. Two sliding sleeves are threadedly connected to the surface of the reverse-threaded lead screws. An L-shaped plate is fixed to the top of the surface of the sliding sleeve. A baffle is fixed to the bottom of the sliding sleeve.

At the same time, the electric turntable can drive the circuit board to rotate. During the rotation of the circuit board, it can be more evenly exposed to the coating medium, which helps the paint to form a uniform coating on the board surface, reducing the phenomenon of local over-thickness or under-thickness and improving the overall coating quality. Then, the electric turntable stops rotating, and the conveyor continues to drive the circuit board for conveyance. Before this, the reduction motor will drive the coating roller to rotate. During the start of the delivery pump, the paint input into the second shunt housing will flow through the drain groove onto the surface of the coating roller, and through the rotation of the coating roller, the surface of the coating roller will be evenly covered with paint. During the continuous conveyance of the circuit board, the surface of the coating roller will come into contact with the surface of the circuit board. When the coating roller contacts the surface of the circuit board, it can help the paint to be more evenly distributed on the board surface through physical pressure, especially for those areas that may be missed or have a thinner coating during the spraying process. The coating roller can play a role in filling and compressing, reducing the discontinuity of the coating. The circuit board passing through the coating roller will be conveyed inside to below the second nozzle. At this time, the blower will convey high-pressure air to the surface of the circuit board through the air delivery pipe, the third shunt housing, and the second nozzle, blowing the surface of the circuit board through the high-pressure air flow to remove the excess paint mist, further promoting the flatness and uniformity of the coating, thereby ensuring the final coating effect of the circuit board, and the air cylinder can adjust the height position of the third shunt housing to avoid damaging the surface of the coating due to the airflow being too close.

Detailed implementation manner

[0020] Please refer to Figures 1-5 , a surface coating device for integrated circuit board production and processing, including a conveyor 1, a mounting housing 2 is fixed on the top of the conveyor 1, an electric turntable 3 is fixed on the belt surface of the conveyor 1, a placing table 4 is fixed on the surface of the electric turntable 3, and a storage tank 6 is fixed on the top of the mounting housing 2;

[0021] The conveyor 1 is used to convey the circuit board, the electric turntable 3 can drive the circuit board to rotate, the surface of the placing table 4 is used to place the circuit board, and the inside of the storage tank 6 is used to store the paint.

[0022] The surface of the storage tank 6 is communicated with a transfer pump 7, the conveying end of the transfer pump 7 is communicated with a shunt pipe 8, the shunt pipe 8 penetrates through the mounting housing 2, one end of the shunt pipe 8 is communicated with a first shunt housing 9, the surface of the first shunt housing 9 is communicated with a first spray head 10, the other end of the shunt pipe 8 is communicated with a second shunt housing 11, both the first shunt housing 9 and the second shunt housing 11 are fixedly connected to the inner wall of the mounting housing 2, a liquid discharge groove 12 is opened at the bottom of the second shunt housing 11, a coating roller 13 is arranged below the second shunt housing 11, a reduction motor 14 is arranged on one side of the coating roller 13, the reduction motor 14 is fixed on the surface of the mounting housing 2, the output shaft of the reduction motor 14 penetrates through the mounting housing 2 and is fixedly connected to the coating roller 13, the coating roller 13 is rotationally connected to the inner wall of the mounting housing 2, a fan 15 is fixed on the top of the mounting housing 2, the surface of the fan 15 is communicated with an air supply pipe 16, the air supply pipe 16 penetrates through the mounting housing 2, a corrugated pipe is installed on the surface of the air supply pipe 16, the bottom of the air supply pipe 16 is communicated with a third shunt housing 17, the surface of the third shunt housing 17 is communicated with a second spray head 18, and two cylinders 19 are fixed on the top of the third shunt housing 17, and the surfaces of the cylinders 19 are fixedly connected to the inner wall of the mounting housing 2;

[0023] The conveyor 1 can drive the electric turntable 3 to move, so that the circuit board on the surface of the electric turntable 3 can be conveyed into the installation shell 2. When the circuit board is conveyed below the first shunt shell 9, the delivery pump 7 is started so that the paint in the storage tank 6 can be sprayed downward through the first shunt shell 9 and the first nozzle 10. At the same time, the electric turntable 3 can drive the circuit board to rotate. During the rotation of the circuit board, it can be more evenly exposed to the coating medium, which helps the paint to form a uniform coating on the board surface, reducing the phenomenon of local over-thickness or under-thickness, improving the overall coating quality. Then the electric turntable 3 stops rotating, and the conveyor 1 continues to drive the circuit board for conveying. Before that, the reduction motor 14 will drive the coating roller 13 to rotate. During the start of the delivery pump 7, the paint input into the second shunt shell 11 will be able to flow into the surface of the coating roller 13 through the drain groove 12, and through the rotation of the coating roller 13, the surface of the coating roller 13 will be evenly covered with paint. During the continuous conveying of the circuit board, the surface of the coating roller 13 will come into contact with the surface of the circuit board. When the coating roller 13 comes into contact with the surface of the circuit board, it can help the paint to be more evenly distributed on the board surface through physical pressure. Especially for those areas that may be missed or have a thinner coating during the spraying process, the coating roller 13 can play a role in filling and compressing, reducing the discontinuity of the coating. And the circuit board passing through the coating roller 13 will be conveyed inside to below the second nozzle 18. At this time, the blower 15 will convey high-pressure air to the surface of the circuit board through the air delivery pipe 16, the third shunt shell 17 and the second nozzle 18, and blow the surface of the circuit board through the high-pressure air flow to remove the excess paint mist, further promoting the flatness and uniformity of the coating, so as to ensure the final coating effect of the circuit board, and the cylinder 19 can adjust the height position of the third shunt shell 17 to avoid damaging the coating surface due to the too-close air flow.

[0024] Further, two screw rods 22 penetrate through the surface of the placement table 4 in a threaded manner. A clamping plate 23 is rotatably connected to the surface of the screw rod 22. A guide rod 24 penetrates through the surface of the placement table 4, and the surface of the guide rod 24 is fixedly connected to the surface of the clamping plate 23;

[0025] Rotating the screw rod 22 can make the clamping plate 23 move, and the guide rod 24 can also slide on the surface of the placement table 4, so that the clamping plate 23 can obtain a guiding effect, enabling the clamping plate 23 to clamp and fix the circuit board, preventing the circuit board from moving during the rotation of the electric turntable 3.

[0026] Further, a plurality of side plates 25 are fixed to the bottom of the second shunt shell 11. Two left-right threaded screw rods 27 are rotatably connected to the surface of the side plates 25. Two sliding sleeves 28 are threadedly connected to the surface of the left-right threaded screw rods 27. The top of the surface of the sliding sleeve 28 is fixedly connected with an L-shaped plate 29, and the L-shaped plate 29 is slidably connected to the inner wall of the second shunt shell 11. The bottom of the sliding sleeve 28 is fixedly connected with a baffle 30, and the baffle 30 is slidably connected to the surface of the coating roller 13;

[0027] When the left - hand and right - hand threaded lead screw 27 rotates, the two sliding sleeves 28 will be affected by the threads and start to move towards each other or in opposite directions. Moreover, the sliding sleeves 28 can also drive the L - shaped plate 29 and the baffle 30 to move together, enabling the L - shaped plate 29 to change the width of the liquid drainage groove 12, thereby reducing the range of the paint flowing onto the surface of the coating roller 13. The baffle 30 can also prevent the paint from dripping onto the parts of the coating roller 13 outside the lower liquid drainage groove 12, enabling the paint on the surface of the coating roller 13 to be accurately applied to the surface of the circuit board and reducing the waste of paint.

[0028] Furthermore, a driving motor 26 is fixed on the surface of one side plate 25. The output shaft of the driving motor 26 penetrates through the side plate 25 and is fixedly connected to the left - hand and right - hand threaded lead screw 27 on one side. A pulley 21 is fixed on the surface of the left - hand and right - hand threaded lead screw 27, and the two pulleys 21 on both sides are connected by a belt in a transmission manner.

[0029] When the driving motor 26 starts, it can drive the left - hand and right - hand threaded lead screw 27 on one side to rotate. And this side's left - hand and right - hand threaded lead screw 27 can drive the left - hand and right - hand threaded lead screw 27 on the other side to rotate through the transmission of the two pulleys 21 and the belt, thus ensuring that the left - hand and right - hand threaded lead screws 27 on both sides can rotate synchronously.

[0030] Furthermore, a cushion block 5 is arranged on the top of the placing table 4. Threaded holes are opened on both the surface of the cushion block 5 and the placing table 4. The cushion block 5 and the placing table 4 are detachably connected by bolts through the threaded holes.

[0031] Through the setting of the cushion block 5, the circuit board can be elevated on the surface of the cushion block 5, so that the height of the surface of the circuit board can be higher than that of the clamping plate 23. And the cushion block 5 can also be replaced according to the size requirements to adapt to circuit boards of different sizes.

[0032] Furthermore, regulating valves 20 are installed on both the surface of the shunt pipe 8 and the air supply pipe 16.

[0033] The regulating valve 20 on the surface of the shunt pipe 8 can adjust the paint flow rate entering the inside of the second shunt housing 11, avoiding the paint overflowing from the surface of the coating roller 13 due to excessive paint flow rate. The regulating valve 20 on the surface of the air supply pipe 16 can control the air pressure inside the third shunt housing 17, achieving more precise control of the air flow intensity blowing towards the surface of the circuit board. In this way, without damaging the coating, the excess paint mist can be effectively removed, ensuring that the purging effect is more precise and controllable.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
