Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a surface processing device for thick copper PCB boards with controllable surface roughness. Background Art

[0002] Thick copper PCBs, also known as printed circuit boards, provide electrical connections for electronic components. PCB circuits and graphics are created simultaneously, resulting in high wiring density, compact size, and light weight, which facilitates the miniaturization of electronic devices. During the PCB manufacturing process, impurities may remain on the surface, necessitating surface treatment to ensure the safety of the PCB.

[0003] The China Patent Network discloses a surface treatment device for PCB board processing, with publication number CN220674022U. Although it is equipped with a clamping block and a lifting mechanism, which can clamp and fix PCB boards of different thicknesses and sizes, ensuring that the PCB boards are in a stable and safe state during processing, and is equipped with a rotating roller brush and an extending roller brush that can be retracted to change the working length of the roller brush, allowing it to act on PCB boards of different sizes, thereby improving the use value of the device, the patent does not allow for adjustment of the roughness of the PCB board surface treatment, and its practicality is relatively low.

[0004] Therefore, a surface treatment device for thick copper PCB boards with controllable surface roughness is proposed. Utility Model Content

A first connecting ear 17 and a second connecting ear 19 are fixed on the outer wall of the rotating disk 12, and a first clamping hole 18 and a second clamping hole 20 are respectively opened on the outer walls of the first connecting ear 17 and the second connecting ear 19; a threaded hole 21 is opened on the outer side of the first L-shaped plate 11, and a threaded member 22 is threadedly connected to the inner thread of the threaded hole 21, a turning bar 23 is fixed to one end of the threaded member 22, and the other end of the threaded member 22 is clamped into the inside of the first clamping hole 18.

[0036] Specifically, the present invention rotates the threaded member 22 by the turning bar 23. At this time, the threaded member 22 will move in the threaded hole 21. After one end of the threaded member 22 is disengaged from the first clamping hole 18, the rotating disk 12 is moved to exchange the positions of the two roller brushes 16. After the positions of the two roller brushes 16 are exchanged, the threaded member 22 is rotated again by the turning bar 23. After one end of the threaded member 22 is clamped into the first clamping hole 18 or the second clamping hole 20, the two roller brushes 16 can be fixed. Compared with the existing ones, the present invention can adjust the two roller brushes 16 to meet the use requirements of different thick copper PCB boards.

[0037] Example 2:

[0038] See also Figure 1 、 34. The utility model provides a technical solution: a surface treatment device for thick copper PCB boards with controllable surface roughness, wherein a limit plate 25 is fixed to the outer wall of the driving rod 15, one end of the limit plate 25 abuts against one end of the roller brush 16, and a connecting thread is provided on the outer wall of the driving rod 15, which is threadedly connected to a limit ring 24, one end of the limit ring 24 abuts against the other end of the roller brush 16, a connecting hole 26 is provided on the outer wall of the limit plate 25, and a third clamping hole 27 is provided at one end of the roller brush 16; a connecting rod 28 is movably provided in the connecting hole 26, an auxiliary plate 29 is fixed to one end of the connecting rod 28, and the other end of the connecting rod 28 is clamped in the third clamping hole 27, a spring 30 is provided on the outer wall of the connecting rod 28, one end of the spring 30 is fixed to the auxiliary plate 29, and the other end of the spring 30 is fixed to the limit plate 25.

[0039] Specifically, the present invention can disassemble the roller brush 16 by rotating the limiting ring 24 and separating the limiting ring 24 from the outer wall of the driving rod 15. Therefore, the present invention facilitates the disassembly and maintenance of the roller brush 16, thereby improving the working efficiency of the roller brush 16.

[0040] And under the action of the spring 30, the connecting rod 28 will be driven to move. After one end of the connecting rod 28 is clamped into the inside of the third clamping hole 27, the roller brush 16 can be prevented from slipping on the outer wall of the driving rod 15, thereby improving the working efficiency of the roller brush 16.

[0041] Working principle:

[0042] First, the threaded member 22 is rotated by the rotating bar 23. At this time, the threaded member 22 will move in the threaded hole 21. After one end of the threaded member 22 is disengaged from the first clamping hole 18, the rotating disk 12 is movable to exchange the positions of the two roller brushes 16. After the positions of the two roller brushes 16 are exchanged, the threaded member 22 is rotated again by the rotating bar 23. After one end of the threaded member 22 is clamped into the first clamping hole 18 or the second clamping hole 20, the two roller brushes 16 can be fixed. Compared with the existing ones, the utility model can adjust the two roller brushes 16 to meet the use requirements of different thick copper PCB boards. The mutual use of the two roller brushes 16 can also achieve the purpose of controlling and adjusting the roughness of the surface treatment of the thick copper PCB board, which is highly practical.

[0043] Next, place the thick copper PCB on top of the workbench 1, and then start the first hydraulic cylinder 4. The first hydraulic cylinder 4 will cooperate with the first hydraulic rod 5 to drive the clamping bar 7 to move. After the two clamping bars 7 abut against the thick copper PCB, the thick copper PCB can be clamped and fixed. Then start the second hydraulic cylinder 9. The second hydraulic cylinder 9 will cooperate with the second hydraulic rod 10 to drive a corresponding roller brush 16 to move downward. At this time, the motor 14 of the corresponding roller brush 16 will drive the roller brush 16 to work through the drive rod 15. After the roller brush 16 contacts the thick copper PCB, the surface of the thick copper PCB can be processed.

[0044] Finally, by rotating the limiting ring 24 and separating the limiting ring 24 from the outer wall of the driving rod 15, the roller brush 16 can be disassembled. Therefore, the utility model facilitates the disassembly and maintenance of the roller brush 16, thereby improving the working efficiency of the roller brush 16.

[0045] And under the action of the spring 30, the connecting rod 28 will be driven to move. After one end of the connecting rod 28 is clamped into the inside of the third clamping hole 27, the roller brush 16 can be prevented from slipping on the outer wall of the driving rod 15, thereby improving the working efficiency of the roller brush 16.
