Description

Technical Field

[0001] The invention relates to the technical field of PCB circuit board coating, and in particular to a corrosion-resistant PCB circuit board coating device. Background Art

[0002] Circuit board coating is a protective layer covering the surface of PCB circuit board. Its main function is to protect the circuit board, prevent circuit board corrosion and enhance the mechanical strength of the circuit board. At the same time, the circuit board may be affected by mechanical friction, corrosion and other factors during actual use, and the circuit board coating can effectively protect the surface of the circuit board and improve the service life of the circuit board.

[0003] A Chinese patent (application number CN202020062090.8) discloses a laminating device for a PCB circuit board, including a laminating machine body, support rods are fixedly installed at the four corners of the bottom of the laminating machine body, the bottom ends of the four support rods are fixedly installed with the same base, rectangular grooves are opened on both sides of the bottom of the base, and screws are rotatably installed on the inner walls of the two rectangular grooves away from each other. The structure is simple, easy to operate, easy to move the laminating machine body, and easy to store the roller, effectively preventing position movement due to accidental contact.

At the same time, dust and impurities are easily attached to the PCB circuit board. If the PCB circuit board is not cleaned, the laminating quality of the PCB circuit board will be reduced, which is not conducive to use. Summary of the invention

The two limit rods 38 can be used to guide the movement trajectory of the U-shaped telescopic plate 39 so that the rubber pressure wheel 41 at the U-shaped telescopic plate 39 can be adjusted and moved smoothly, so that the elastic rubber pressure wheel 41 can be used to adaptively adjust the tension of the conveying of the second film 21. The outer surfaces of the two limit rods 38 are slidably connected to the inside of the side plate 35. One side of the U-shaped telescopic plate 39 passes through the cross plate 37 and extends to the other side of the cross plate 37.

Then, the two PCB circuit board bodies 12 are sequentially placed above the first film 10, and the first electric push rod 14 drives the mounting frame 16 to move downward, so that the second films 21 at the two second rollers 19 can be attached to the top of the two PCB circuit board bodies 12, and then the heating rod 31 is powered on for heating, so that the heat sealing frame 6 at the fixing frame 28 can be heated to the heat sealing temperature. At this time, the second electric push rod 26 can drive the fixing frame 28 to heat up to the heat sealing temperature. The fixed frame 28 moves downward, so that the heat-sealing frame 6 at the fixed frame 28 can heat-seal the first film 10 and the second film 21, and the cutter 30 at the extension plate 29 can also cut the two films after heat sealing, so that the PCB circuit board can be coated, so that the PCB circuit board after coating can be taken out, so that the PCB circuit board has corrosion resistance and extends the service life of the PCB circuit board. At the same time, with the rotation of the first roller 9 and the third roller 20, the used film can be rolled up, so that the new film can be transported to the top of the PCB circuit board body 12, so as to coat the next group of PCB circuit boards and ensure the continuous processing of the coating device.
