Technical Field

[0001] This utility model relates to the field of circuit board coating tooling technology, IPC classification number: B05B13 / 02, and particularly to a coating tooling for electronic boards. Background Technology

[0002] Electronic circuit board coating fixtures are specialized equipment or tools used in the electronics manufacturing industry. Their main function is to uniformly coat electronic circuit boards (PCBs) with materials such as insulating varnish, solder paste, solder resist, and antioxidants. The purpose of coating is usually to protect the circuit board from environmental influences and improve its reliability and stability.

[0003] As disclosed in application number CN202322988650.9, a tooling for coating PCB boards with three-proof coating includes an upper fixture and a lower fixture for clamping the PCB board. The lower fixture is a shell with an open top, and four support platforms are provided on the inner wall of the lower fixture. The support platforms are provided with pin holes that match the positions of the mounting holes on the PCB board. The upper fixture is provided with through holes for spraying paint. The upper fixture 1 is also provided with positioning pins that match the pin holes. The front side of the PCB board rests on the top of the support platforms.

[0004] However, existing electronic board coating fixtures often have limitations; they are typically only suitable for precise clamping and coating operations on electronic boards of specific sizes and models. When faced with electronic boards of different sizes or design requirements, existing fixtures may not be directly applicable. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a coating fixture for electronic boards.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] Example 1, combined with Figure 1 and Figure 2 Explanation:

[0028] A coating fixture for electronic boards includes: a rectangular hollow frame 1, on which transverse grooves 2 and longitudinal grooves 3 are symmetrically provided; a transverse sliding plate 4 is slidably connected to the longitudinal grooves 3; the transverse sliding plate 4 and the longitudinal grooves 3 are fixedly connected by a first locking component 5; a longitudinal sliding plate 6 is slidably connected to the transverse grooves 2; the longitudinal sliding plate 6 and the transverse grooves 2 are fixedly connected by a second locking component 7; and at least two sets of limiting sliding block assemblies 8 are slidably provided on the transverse grooves 2, longitudinal grooves 3, transverse sliding plate 4, and longitudinal sliding plate 6.

[0029] By sliding the horizontal slide plate 4 and the vertical slide plate 6 on the rectangular hollow frame 1 of the tooling, the positions of the horizontal slide plate 4 and the vertical slide plate 6 can be freely adjusted according to the size and specifications of the electronic board to meet the clamping requirements. By setting the first locking component 5 and the second locking component 7, the horizontal slide plate 4 and the vertical slide plate 6 can be fixed after the positions of the horizontal slide plate 4 and the vertical slide plate 6 are adjusted to prevent the horizontal slide plate 4 and the vertical slide plate 6 from shifting during the coating process. By setting the limiting sliding block component 8, the electronic board can be supported and limited. The position of the limiting sliding block component 8 can also be adjusted according to the arrangement of electronic components on the electronic board to avoid the electronic components.

[0030] Example 2, based on Example 1, combined with... Figure 3 Explanation:

[0031] The transverse groove 2 and the longitudinal groove 3 are inverted T-shaped grooves.

[0032] Both the transverse sliding plate 4 and the longitudinal sliding plate 6 are provided with grooves, which are inverted T-shaped grooves, and the cross-section of the grooves is the same as that of the transverse sliding groove 2 and the longitudinal sliding groove 3.

[0033] The wider section of the slide is used to accommodate the screw cap, while the narrower section is through which the screw passes. This design prevents the screw cap from extending beyond the bottom surface of the rectangular hollow frame 1 of the fixture, thus avoiding imbalance when the rectangular hollow frame 1 of the fixture is placed.

[0034] Example 3, based on Example 2, combined with Figure 4 Explanation:

[0035] The longitudinal slide plate 6 includes: a longitudinal slide plate body 61 and a connecting block 62. The connecting block 62 is provided in two sets. The two sets of connecting blocks 62 are fixedly connected to both ends of the longitudinal slide plate body 61. The longitudinal slide plate body 61 is located on the lower side of the transverse slide plate 4. The two sets of connecting blocks 62 are slidably connected to the transverse slide groove 2. The connecting block 62 is fixedly connected to the transverse slide groove 2 through the second locking component 7.

[0036] This design prevents interference between the longitudinal sliding plate body 61 and the transverse sliding plate 4 during movement, ensuring the smooth operation of the entire device.

[0037] Example 4, based on Example 3, combined with Figure 5 Explanation:

[0038] The second locking component 7 has the same structure as the first locking component 5.

[0039] The first locking component 5 includes a flat-bottomed screw 51 and a wing nut 52, wherein the wing nut 52 and the flat-bottomed screw 51 are connected by threads.

[0040] With this configuration, the wing nut 52 is easy for workers to tighten or loosen. Two sets of the second locking component 7 and the first locking component 5 are provided, respectively located at both ends of the transverse slide plate 4 and the longitudinal slide plate 6.

[0041] Example 5, based on Example 4, combined with Figure 6 Explanation:

[0042] The limiting sliding block assembly 8 includes: a sliding plate 81, a screw 82, and a nut 83. The sliding plate 81 is slidably disposed on the transverse slide groove 2, the longitudinal slide groove 3, the transverse slide plate 4, or the longitudinal slide plate 6. The sliding plate 81 is fixedly connected to the transverse slide groove 2, the longitudinal slide groove 3, the transverse slide plate 4, or the longitudinal slide plate 6 by the screw 82 and the nut 83. The screw 82 and the nut 83 are connected by threads.

[0043] With this configuration, the limiting sliding block assembly 8 has a total of eight sets, with two sets arranged adjacent to each other on the four sides of the electronic board, for supporting and clamping the electronic board.

[0044] The working principle of this utility model is as follows: When using this utility model, the positions of the horizontal sliding plate 4 and the vertical sliding plate 6 are adjusted horizontally and vertically according to the size of the electronic board, so that the sliding support plate 81 can support, lift and clamp the electronic board from all sides. Finally, the nut 83 and the wing nut 52 are tightened and fixed, and then the electronic board can be coated. This utility model has a reasonable structure and is easy to use. The positions of the horizontal sliding plate and the vertical sliding plate can be freely adjusted according to the size and specifications of the electronic board to meet the clamping requirements.
