Problems solved by technology

[0005] 1. The development, etching and film removal processes cannot be concentrated on the same equipment at the same time, and the production requirements can not be completed at one time. At the same time, the degree of automation is low, and the production equipment lacks a control system, resulting in many adjustments on the equipment requiring manual operation. Reduced work efficiency
[0006] 2. During the transmission of printed circuit boards, problems such as slipping and offset are prone to occur, resulting in reduced transmission effects and affecting the effects of developing, etching and film removal
[0007] 3. During the etching process, due to the unreasonable structural design of the equipment, the etching liquid flows out from the edge area of ​​the circuit board, while the central area of ​​the circuit board accumulates to form a pool and produce a pool effect
[0008] 4. With the continuous expansion of the production scale of printed circuit boards, a lot of waste will naturally be generated. Due to the poor filtration and recovery effect and unreasonable design of the existing printed circuit board production equipment, the pollution of the waste to the indoor and outdoor environments has already Seriously affect the working and living environment, and there are many recyclable raw materials in the waste, resulting in waste and increased production costs

Abstract

The invention discloses an etching machine, comprising a control system and a board feeding mechanism, a develop mechanism, an etching mechanism, a film stripping mechanism, a dehydration drying mechanism and a boarding ejecting mechanism that are connected with the control system and arranged successively. The board feeding mechanism, the develop mechanism, the etching mechanism, the stripping mechanism, the dehydration drying mechanism and the boarding ejecting mechanism are connected through individually arranged gearings; the develop mechanism, the etching mechanism and the stripping mechanism are respectively connected with sectional exhaust apparatuses, filtering apparatuses and pumping units. The invention can organically combine operations of development, etching and film stripping and complete a whole manufacture process in one piece of equipment, has high degree of automation, reasonable design, good plating and filtering recovery effects and brings huge benefits to relative industries.

Description

technical field [0001] The invention relates to the technical field of printed circuit board production equipment, in particular to an etching machine. Background technique [0002] With the rapid development of electronic technology, the integration of printed circuit boards is getting higher and higher, and the conductive lines of printed circuit boards are made more and more finely. This requires strict control, reduced tolerances, and better uniformity when producing printed circuit boards. . [0003] The existing wet-type printed circuit board production equipment has low cost and simple operation, and is widely used in the production of printed circuit boards. The basic process of printed circuit board production generally includes the development process, etching process and film removal process. The development process refers to the use of developer solution to dissolve the part of the film that has not been irradiated by ultraviolet rays, and the part that has been...
