Etching solution recycling device and utilization method thereof

Abstract

The invention discloses an etching solution recycling device, which comprises a gantry (1) and an etching tank (2) arranged below the cross beam of the gantry (1), wherein a lifting oil cylinder (3) is fixedly mounted at the top of the cross beam of the gantry (1), a lifting plate (4) is welded at the acting end of the piston rod of the lifting oil cylinder (3), the lower end portion of a hollow pipe (5) penetrates through the cross beam, a bearing disc (6) positioned right above the etching tank (2) is welded at the extending end, a plurality of bearing tables (8) distributed in an array modeare welded to the top of the bearing disc (6), a longitudinally-formed groove (9) is formed in the top of each bearing table (8), a circuit board (10) is inserted into each groove (9), and nozzles (11) located on the bearing disc (6) are arranged on the left side and the right side of each bearing table (8). The etching solution recycling device has the beneficial effects that the structure is compact, the etching efficiency is greatly improved, the etching cost is greatly reduced, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of circuit board etching, in particular to an etchant recycling device and a utilization method thereof. Background technique [0002] The circuit board is an important part of the electric vehicle circuit unit, and its design is mainly layout design; the main advantage of the circuit board is that it greatly reduces the errors of wiring and assembly, and improves the automation level and production labor rate. The core process of the circuit board manufacturing process is etching. The required circuit pattern can be made on the circuit board through the etching process. Before etching the circuit board, tape is used to paste the adhesive layer on the substrate of the circuit board to block the area that does not need to be etched. Then soak the entire substrate into the etching tank filled with etching solution. After a period of etching, the circuit layer can be etched on the substrate to form the required...

Problems solved by technology

[0003] After the worker salvages the circuit board, a large amount of etching solution will inevitably adhere to the surface of the circuit board. In order to keep the surface clean, the worker will use clear water to wash away the etching solution attached to the surface of the circuit board to ensure the cleanliness of the product. , which undoubtedly causes the volume of the etching solution in the etching tank to decrease, and new etching solution needs to be continuously replenished later, which undoubtedly increases the etching cost

In addition, during the etching process, the concentration of the etching solution around the circuit board gradually decreases, and the etching solution is not flowing, so it takes a long time to complete the etching, which undoubtedly reduces the etching efficiency and reduces the PCB board. production efficiency
