Description

Technical Field

[0001] The utility model relates to the technical field of tin stripping machines, and particularly relates to a film stripping, etching and tin stripping machine for multi-layer circuit boards. Background Art

[0002] In the prior art, the tin stripping water in the etching and tin stripping machine often cannot be recycled, resulting in waste. Moreover, the tin stripping water is often directly sprayed on the multi-layer high-precision circuit board, and there is a phenomenon of uneven spraying, which reduces the tin stripping efficiency of the etching and tin stripping machine. After the multi-layer high-precision circuit board is stripped of tin by the etching and tin stripping machine, the multi-layer high-precision circuit board is often wet, which will not only take away a part of the tin stripping water, but also is not easy for the next processing step and needs to be naturally air-dried, having certain drawbacks.

[0003] In the patent with the publication number CN209994653U, a film stripping, etching and tin stripping machine for multi-layer high-precision circuit boards is proposed. In this patent, it includes a tin stripping machine body, a spraying device, a spray head, a circulation pipeline, an electric heating plate, a flushing plate, an installation mesh cylinder, a rotating shaft, a water pump, a tin stripping water tank, a reduced pipe section, a screw rod, and a fixing nut. Open the two semi-cylindrical structures that make up the installation mesh cylinder 7, install the multi-layer high-precision circuit board inside it, and the two semi-cylindrical structures are fixed to each other through the mutually fitting fixing edges 17, which is convenient for disassembly and use. Then, the water pump 10 extracts the tin stripping water from the tin stripping water tank 12 and sprays it down from the spray head 3 below the spraying device 2. After spraying through the through holes 15 on the installation mesh cylinder 7, it enters the inside of the installation mesh cylinder 7 to perform tin stripping treatment on the circuit board inside. When spraying on the flushing plate 6, the installation mesh cylinder 7 rotates around the rotating shaft 8, achieving the purpose of spraying tin stripping water while rotating, with uniform tin stripping and good effect. Moreover, the installation mesh cylinder 7 uses the power of water spraying to rotate, which is energy-saving and environmentally friendly. When the tin stripping water falls into the circulation inlet 13 from the installation cylinder 7, it is briefly filtered through the filter screen 11, and then enters the tin stripping water tank 12 again for recycling. After the tin stripping is completed, it is dried by the electric heating plate 5. During the drying process, the moisture rises and condenses into water droplets and drips back into the tin stripping water tank 12 again to achieve circular utilization. However, there are still the following problems in this patent:

[0004] The existing tin stripping machine cannot adjust the spraying structure when spraying tin stripping water on the multi-layer high-precision circuit board, cannot ensure uniform spraying work, and cannot spray tin stripping water on two multi-layer high-precision circuit boards simultaneously.
