Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and more specifically, to an etching apparatus for circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are providers of electrical connections for electronic components. During the manufacturing process, copper traces need to be fabricated on the PCB. These copper traces are quite fine. During the manufacturing process, etching equipment is usually used to process the copper traces on the PCB. A copper plate and a photomask need to be covered on the surface of the circuit board. The PCB is then immersed in different etching solutions in sequence to dissolve the copper plate and the photomask. After the photomask is dissolved, the copper traces remain.

[0003] Currently, when etching circuit boards, the circuit boards need to be manually fixed to the top of the etching solution bath, which is inconvenient to install. At the same time, the etching solution also poses a safety risk to the workers. Utility Model Content

In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0027] This utility model provides an etching device for circuit boards, such as... Figure 1 and 2 As shown, it includes a solution tank 1, and a movable frame 10 is provided on the outside of the upper end of the solution tank 1. An electric telescopic rod 12 is provided on the upper end of the movable frame 10.

[0028] The output end of the electric telescopic rod 12 is equipped with a lifting frame 14 inside the movable frame 10. The operator can control the electric telescopic rod 12 to work through an external control device. The output end of the electric telescopic rod 12 will drive the lifting frame 14 to lift and lower. The lower end of the solution tank 1 is equipped with multiple support blocks 5. The upper end of the solution tank 1 is equipped with a first solution chamber 2, a drying chamber 3 and a second solution chamber 4 in sequence. The operator will add an appropriate amount of alkaline solution inside the first solution chamber 2 and an appropriate amount of etching solution inside the second solution chamber 4.

[0029] The solution tank 1 has support rails 6 on both sides of its outer end face, and rangefinders 8 on both sides of its outer end face. The outer end face of the support rails 6 has multiple support movable blocks 7, and the inner end face of the support movable blocks 7 has a concave fitting groove 11. The support rails 6 can support the support movable blocks 7, thereby facilitating the movement of the movable frame 10.

[0030] A distance measuring plate 9 is provided in the middle of the lower end of the supporting movable block 7. The laser emitted by the distance measuring instrument 8 will illuminate the upper end of the distance measuring plate 9 to detect the position of the distance measuring plate 9. The output end of the electric telescopic rod 12 passes through the end face of the movable frame 10 and extends into the interior of the movable frame 10. Limiting slide rods 13 are provided on both sides of the upper end of the lifting frame 14. When the electric telescopic rod 12 drives the lifting frame 14 to lift or lower, it will also drive the limiting slide rods 13 to lift or lower simultaneously, thereby effectively increasing the stability of the lifting frame 14 when lifting or lowering.

[0031] The limiting slide bar 13 passes through the end face of the movable frame 10 and extends to the upper end of the movable frame 10. The electric telescopic rod 12 is electrically connected to the external control device. The outer end face of the support guide rail 6 is adapted to the inner end face of the concave adapter groove 11.

[0032] The rangefinder 8 is electrically connected to an external control device. The rangefinder 8 is a commercially available LR-TB2000CCL laser rangefinder.

[0033] like Figure 3 and 4 As shown, a plurality of U-shaped hooks 21 are provided on one side of the lower end of the lifting frame 14, and a plurality of mounting hooks 15 are provided on the side of the lower end of the lifting frame 14 away from the U-shaped hooks 21. One end of the mounting hook 15 passes through the end face of the lifting frame 14 and extends to the upper end of the lifting frame 14.

[0034] One end of the mounting hook 15 is provided with a limiting plate 22 at the upper end of the lifting frame 14. The outer end face of the mounting hook 15 is provided with a support spring 23 on the lower side of the limiting plate 22. The support spring 23 will press against the limiting plate 22, so that the mounting hook 15 moves upward inside the lifting frame 14. The U-shaped hook 21 is provided with a mounting rod 16 inside. When the mounting hook 15 moves upward, the mounting rod 16 will be pulled upward by the mounting hook 15, thereby effectively increasing the stability and convenience of the mounting rod 16 during installation.

[0035] The mounting rod 16 has limiting sleeves on both sides of its outer end face, a limiting sliding sleeve 17 in the middle of its outer end face, a circuit board clamp 18 at the lower end of the limiting sliding sleeve 17, and a limiting lever 20 in the middle of the inner end face of the circuit board clamp 18.

[0036] An adjusting rod 19 is provided on one side of the upper end of the circuit board clamp 18. The outer end face of the mounting rod 16 is adapted to the inner end face of the U-shaped hook 21 and the mounting hook 15. The inner end face of the limiting sleeve 17 is adapted to the outer end face of the mounting rod 16. The limiting lever 20 is adapted to the openings at the four corners of the circuit board. The operator can open the circuit board clamp 18 by pressing the adjusting rod 19, and then the openings at the four corners of the circuit board can be locked in the outer end face of the limiting lever 20. Then the adjusting rod 19 can be released, and the circuit board clamp 18 will clamp the circuit board.

[0037] Then, the staff can insert one end of the installation rod 16 into the U-shaped hook 21, then press down the limiting plate 22 and lock the other end of the installation rod 16 into the installation hook 15. The support spring 23 will then press against the limiting plate 22, causing the installation hook 15 to move upward, thereby pulling up the installation rod 16. After the circuit board is installed stably, the staff can use the electric telescopic rod 12 to drive the lifting frame 14 to descend, so that the circuit board is completely submerged in the interior of the second solution chamber 4, and the copper exposed on the surface of the circuit board will dissolve.

[0038] After soaking for a period of time, the lifting frame 14 is raised and the movable frame 10 is moved to the upper end of the drying chamber 3. After standing for a period of time to allow the solution on the surface of the circuit board to dry, the movable frame 10 can be moved to the upper end of the first solution chamber 2 so that the circuit board is immersed in the solution inside the first solution chamber 2, and the photomask on the surface of the copper traces of the circuit board will dissolve.
