Technical Field
[0001] The utility model belongs to the field of electronic component processing technology, and particularly relates to an automatic film slag recovery device for film stripping of a circuit board etching line. Background Art
[0002] At present, the film residue after film stripping in the etching stripping line is still recycled in a rotating barrel. The disadvantage is that the dry film is easy to fall into the tank in the rotating barrel after film stripping recovery. However, after the dry film washed off in the film stripping process falls into the chemical pool, it will be pumped back to the spray assembly by the water pump to spray the PCB board. This will cause the washed dry film to adhere to the subsequent PCB board, which will affect the development and film stripping effect of the chemical solution, as well as the quality of the PCB board, resulting in the need to replace the chemical solution in advance, increasing the cost of wastewater treatment and chemical use.
[0003] Based on this, in order to effectively remove film residues and reuse the solution to save costs, this design proposes an automatic film residue recovery device for circuit board etching line stripping. Summary of the invention

[0006] Preferably, the filter barrel comprises: filter plate A, filter cloth, filter plate B, and filter plate C. The side of the filter barrel is composed of 3 filter plates and filter cloth. The filter plate A is in the innermost layer. The filter cloth is laid on the outside of the filter plate A, and the filter plate B is installed on the outside of the filter cloth. The filter cloth is laid on the outside of the filter plate B, and the filter plate C is installed on the outside of the filter cloth. The filter plates A, B, and C are all provided with filter holes. The filter holes of the filter plates A and C have the same diameter and number and are evenly distributed. The filter hole diameter of the filter plate B is smaller than that of the filter plates A and C, and the filter hole positions of the filter plate B are staggered from the filter holes of the filter plates A and C.

[0011] 1. The utility model can filter the film residue after the film is stripped off the etching line by arranging a filter barrel. During filtering, since the filter barrel is composed of filter cloth and filter plate, the filter holes between the filter plates are staggered. While the liquid is rotated by the rotation of the agitator, the medicine will be filtered out through the filter holes and the filter cloth, while the film residue will be blocked by the filter holes and the filter cloth and will remain in the filter barrel. The convex block arranged on the agitator can increase the liquid rotation force and thus provide the medicine with a lateral force to promote the rapid filtration of the medicine. At the same time, the film residue close to the center can also be thrown to the filter cloth and filter plate of the filter barrel, so that the film residue can be effectively adhered and retained in the filter barrel.
