[0002] PCB boards typically require a layer of conformal coating. This coating process necessitates the use of a spray painting fixture. Traditional spray painting fixtures are usually placed directly on a workbench or inside a frame. However, the workbench or frame may not be well-suited for the electrical components on the PCB board, leading to collisions between these components and other parts. Additionally, the PCB board may slip off the workbench or frame, resulting in board drops. Both of these issues can cause PCB board defects and increase the defect rate. Utility Model Content

[0003] The technical problem to be solved by this utility model is how to design a universal base for PCB board spraying fixtures so that the PCB board spraying fixtures can be well fixed on the universal base, so as to avoid collisions with other components and limit the PCB board to prevent the PCB board from slipping, that is, to prevent collisions and board falling, thereby improving product yield, reducing product costs and improving product competitiveness.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: To solve the above-mentioned technical problems, this utility model provides a universal base for a PCB board painting fixture, which includes a base plate, side limiting blocks, support blocks, bottom edge limiting blocks, and a movable baffle. The base plate is square in shape. There are two side limiting blocks, which are respectively disposed on the two sides of the long side of the base plate. There are two support blocks, both of which are disposed on the base plate and are located inside the two side limiting blocks. The height of the side limiting blocks is higher than the height of the support blocks.

[0027] Example 1, please refer to Figures 1 to 4This utility model provides a universal base for a PCB board painting fixture, comprising a base plate 1, side limiting blocks 2, support blocks 3, bottom edge limiting blocks 4, and a movable baffle 5. The base plate 1 is square in shape. There are two side limiting blocks 2, which are respectively disposed on the two sides of the long side of the base plate 1. There are two support blocks 3, both of which are disposed on the base plate 1 and are located inside the two side limiting blocks 2 respectively.

The bottom edge limiting block 4 is disposed on the short side of one side of the base plate 1, and a support groove 41 is formed on the inner side of the bottom edge limiting block 4. The movable baffle 5 is disposed on the short edge of the other side of the base plate 1, and the movable baffle 5 can slide back and forth along the long side of the base plate 1 and be fixed. Because the base plate 1 is equipped with support blocks 3 and support grooves 41, it can support the PCB board painting fixture to a sufficient height to prevent the electrical components of the PCB board on the PCB board painting fixture from interfering with and colliding with the base plate 1, thereby preventing collisions. The side limit blocks 2 and bottom limit blocks 4 on the outer side of the support blocks 3 can effectively limit the PCB board painting fixture at the support blocks 3 and support grooves 41, preventing the PCB board painting fixture from sliding and thus preventing board drop, improving product yield, reducing product cost and improving product competitiveness. In addition, a movable baffle 5 is provided on the short edge of the other side of the base plate 1, so that the other half of the PCB board painting fixture can lean against the movable baffle 5, so that the PCB board painting fixture can be fully unfolded. The movable baffle 5 can slide back and forth and be fixed along the long side of the base plate 1, so that it can adapt to PCB board painting fixtures of different lengths, thereby improving the versatility of the base.

[0028] Furthermore, a racetrack-shaped through hole 11 is provided on the base plate 1, and the movable baffle 5 is fixed to the racetrack-shaped through hole 11 by fixing screws, so that the movable baffle 5 can slide back and forth and be fixed along the long side of the base plate 1, so that it can adapt to PCB board painting fixtures of different lengths, thereby improving the versatility of the base.

[0029] Furthermore, a slide rail is provided on the base plate 1, and a slider corresponding to the slide rail is provided on the movable baffle 5, so that the movable baffle 5 can slide back and forth along the long side of the base plate 1 and be fixed, so that it can adapt to PCB board painting fixtures of different lengths, thereby improving the versatility of the base.

[0030] Furthermore, there are two movable baffles 5, which are respectively set at the two top corners of the short side on the other side of the base plate 1, so that the PCB board painting fixture can be fully unfolded.

[0031] Furthermore, there are two bottom edge limiting blocks 4, which are respectively set on the two apex corners of the short side of one side of the base plate 1, thereby limiting the two apex of the PCB board painting fixture.

[0032] Furthermore, the height of the bottom edge limiting block 4 is flush with the height of the side edge limiting block 2, and the height of the support groove 41 is flush with the height of the support block 3, so that the PCB board painting fixture can be placed flat on the support groove 41 and the support block 3.

[0033] Furthermore, the side limiting block 2 and the support block 3 are spaced apart to form a channel.

[0034] Furthermore, the height of the movable baffle 5 is higher than the height of the support block 3 and the support groove 41, so that another part of the PCB board painting fixture can be higher than the support groove 41 and the support block 3, thereby preventing the PCB board painting fixture from slipping and preventing parts from falling off.

[0035] Furthermore, the height of the support block 3 and the support groove 41 is 15cm-25cm, so that the clearance between the support block 3 and the support groove 41 has enough space to accommodate components or heat sinks on the PCB board. The height of the movable baffle 5 is 25cm-35cm, so that another part of the PCB board painting fixture can be higher than the support groove 41 and the support block 3, thereby preventing the PCB board painting fixture from slipping and preventing parts from falling off. The height of the side limiting block 2 is 2cm-5cm higher than the height of the support block 3, thereby limiting the PCB board painting fixture.
