Description

Technical Field

[0001] The utility model relates to the technical field of film stripping and filtration, in particular to an etching film slag separation and collection device. Background Art

[0002] For the stripping section of the etching line in the circuit board production process, stripping refers to a process in the production process. After the etching process, the board has obtained the required pattern, but this layer of pattern is etched under the protection of dry film or wet film. Because the etching solution will corrode the conductive metal, we use dry film or wet film to protect the required pattern, but after obtaining the required pattern. The dry film or wet film covering the board must be removed. The packaged film residue contains a large amount of water components, and a special film residue supplier must be invited to purchase it. Since the film residue has not been specially treated, the internal water content accounts for more than 50% of the weight, which increases the additional cost;

[0003] Existing membrane residue filtration usually utilizes filter mesh filtration, which results in a large filter mesh load and is prone to clogging, affecting the backflow of the film stripping liquid, thereby requiring frequent cleaning and residue removal. The film stripping device needs to be shut down when the filter mesh is cleaned, which in turn affects the production efficiency of the circuit board. Therefore, in order to solve the problem of cleaning the filter mesh without affecting production, an etching membrane residue separation and collection device is designed. Utility Model Content

The conveying mechanism 3 is located below the film outlet 13, and a large volume of film residue will enter the conveying mechanism 3 from the film outlet 13 and be transported to the collection point, while a small volume of film residue and the liquid in the film residue will flow out from the circular holes into the filter tank 2, and the liquid is filtered through the filter holes, so that the liquid flows into the liquid collecting pool 4, while a small volume of film residue is retained in the filter tank 2, and the filter tank 2 is located below the dehydration mechanism 1, which is convenient to clean, and no additional shutdown is required for cleaning, thereby improving production efficiency.
