Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a circuit board conformal coating protection device. Background Technology

[0002] Electronic products require robust protection during use, storage, and transportation, withstanding environments exposed to smoke, humidity, and mold. Conformal coatings are specially formulated paints used to protect circuit boards and related equipment from environmental damage.

[0003] According to Chinese Patent Application No. CN201922121786.3, a protective device for spraying conformal coating on circuit boards is disclosed. By setting the upper protective plate and the upper frame on the same plane, and setting the support plate and the lower frame in a staggered manner, the height between the surface of the support plate and the upper surface of the lower frame is equal to the height of the circuit board substrate. In this way, when the upper frame and the lower frame are locked by the locking mechanism, the circuit board is placed only between the support plate and the upper protective plate on the upper frame, which greatly reduces the height between the protective plate and the circuit board, minimizes the phenomenon of conformal coating being sprayed through the height space due to the existence of height space, and maximizes the coating effect.

[0004] Currently, there are still some shortcomings in the protective device for spraying conformal coating on circuit boards. For example, when spraying paint, different circuit boards require different positions to be shielded and protected, and the position of the upper frame protection cannot be changed, so it cannot be adapted to protect different circuit boards when spraying paint. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circuit board conformal coating protection device, which solves the problem that when different circuit boards require different shielding and protection positions, the upper frame protection position cannot be changed, making it unsuitable for protecting different circuit boards during coating.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A circuit board conformal coating protection device includes: a placement plate, the top surface of which has two placement slots, the top surface of which a circuit board is placed, and the top surface of the circuit board is provided with a protective frame; and a shielding component, which is disposed on the top surface of the protective frame and is used to shield the paint spraying.

[0008] By adopting the above technical solution and setting up a shielding component, when the circuit board is coated with conformal coating, the shielding component can shield the areas on the circuit board where conformal coating is not allowed to be sprayed, thereby improving the convenience of shielding.

[0009] Preferably, the shielding component includes: a plurality of slots, all of which are formed on the top surface of the protective frame, wherein a support rod is movably engaged inside the plurality of slots, a magnetic block is fixedly adhered to the top surface of the support rod, and a shield is provided on the top surface of the magnetic block.

[0010] By adopting the above technical solution and setting up a mask, when in use, the staff can adjust the mask according to the different masking positions on the circuit board. Where no masking is needed, the support rod can be removed. Where masking is needed, after the support rod is set up, the mask is attached to the magnetic block of the support rod. This makes it convenient to mask different positions according to different circuit boards, thus meeting the paint protection needs of different circuit boards.

[0011] Preferably, the top surface of the placement plate is provided with a plurality of movable slots, the bottom surface of the movable slots is fixedly installed with movable columns, the movable columns are movably fitted with connecting cylinders, and the connecting cylinders are fixedly connected to the protective frame.

[0012] By adopting the above technical solution and setting up a movable column, when the circuit board is placed on the placement plate, the staff pulls up the protective frame. The protective frame slides on the movable column through the connecting cylinder to prevent the position of the protective frame from shifting during the movement. After the circuit board is placed, the protective frame is released and covers the circuit board.

[0013] Preferably, a limit block is fixedly installed on the top surface of the movable column, and a spring is provided on the outside of the movable column.

[0014] By adopting the above technical solution and setting a spring, when the circuit board is placed between the placement plate and the protective frame, the protective frame presses the circuit board on the placement plate with the spring, fixing the position of the circuit board and preventing the circuit board from shifting during the painting process.

[0015] Preferably, a rubber pad is fixedly adhered to the bottom surface of the protective frame.

[0016] By adopting the above technical solution and setting rubber pads, when the protective frame is pressed down to fix the circuit board, the rubber pads prevent the protective frame from pressing down too much and causing damage to the circuit board.

[0017] Preferably, two handles are fixedly installed on the top surface of the protective frame.

[0018] By adopting the above technical solution and setting a handle, after the painting is completed, the staff can easily pull the protective frame upwards and take out the painted circuit board by pulling the handle upwards.

[0019] In summary, the present invention has the following main advantages:

[0020] By setting up a shield, when in use, the staff can adjust the shield according to the different shielding positions on the circuit board. Where no shielding is needed, the support rod can be removed. Where shielding is needed, after the support rod is set up, the shield is attached to the magnetic block of the support rod. This makes it convenient to shield different positions according to different circuit boards, meeting the different circuit board spraying protection needs.

[0021] By incorporating springs, when the circuit board is placed between the placement plate and the protective frame, the protective frame presses the circuit board on the placement plate firmly through the springs, fixing the position of the circuit board and preventing it from shifting during the painting process.

By setting the shielding component, when the circuit board 3 is coated with conformal coating, the shielding component can shield the areas on the circuit board 3 where conformal coating is not allowed to be sprayed, thereby improving the convenience of shielding.

[0028] refer to Figure 1 , Figure 2The shielding component includes several slots 5, all located on the top surface of the protective frame 4. Each slot 5 has a support rod 6 that is movably engaged within it. A magnet 7 is fixedly adhered to the top surface of the support rod 6, and a shield 8, made of iron, is mounted on the top surface of the magnet 7. The magnet 7 and the shield 8 are attracted to each other. By using the shield 8, workers can adjust it according to the different shielding positions on the circuit board 3. Where shielding is not required, the support rod 6 can be removed. Where shielding is required, the support rod 6 is erected, and the shield 8 is attached to the magnet 7 on the support rod 6. This allows for convenient shielding of different positions on different circuit boards 3, meeting the painting protection needs of different circuit boards 3.

Movable columns 10 are fixedly installed on the bottom surface of the inner side of each movable slot 9. Connecting cylinders 11 are movably fitted inside the movable columns 10 and are fixedly connected to the protective frame 4. By setting the movable columns 10, when the circuit board 3 is placed on the placement plate 1, the operator pulls up the protective frame 4. The protective frame 4 slides on the movable columns 10 via the connecting cylinders 11, preventing the protective frame 4 from shifting during movement. After the circuit board 3 is placed, the protective frame 4 is released, covering the circuit board 3. Limit blocks 12 are fixedly installed on the top surface of the movable columns 10, and springs 13 are provided on the outside of the movable columns 10. By setting the springs 13, when the circuit board 3... When placed between the placement plate 1 and the protective frame 4, the protective frame 4 presses the circuit board 3 on the placement plate 1 with the spring 13 to fix the position of the circuit board 3 and prevent the circuit board 3 from shifting during the painting process. The bottom surface of the protective frame 4 is fixedly glued with a rubber pad 14. By setting the rubber pad 14, when the protective frame 4 is pressed down to fix the circuit board 3, the rubber pad 14 prevents the protective frame 4 from pressing down too much and damaging the circuit board 3. The top surface of the protective frame 4 is fixedly installed with two handles 15. By setting the handles 15, after the painting is completed, the staff can pull the handles 15 upward to easily lift the protective frame 4 and take out the painted circuit board 3.

[0030] Working principle: Please refer to Figures 1-3As shown, during use, the operator pulls up the protective frame 4, at which point the spring 13 is compressed. After the circuit board 3 is placed on the placement plate 1, the protective frame 4 is released, the spring 13 springs out, and the protective frame 4 presses the circuit board 3 firmly, fixing the position of the circuit board 3. Depending on the different blocking positions on the circuit board 3, the shield 8 is adjusted. Where no blocking is needed, the support rod 6 can be removed. Where blocking is needed, after the support rod 6 is erected, the shield 8 is attached to the magnetic block 7 of the support rod 6, thus facilitating the blocking of different positions according to different circuit boards 3, meeting the paint protection needs of different circuit boards 3.
