Embodiment Construction
[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

An automatic etching device comprises a board feeding device, a developing device, a first inspection device, an etching device, a second inspection device, a bulking device, a membrane retreat device and a board out-coming device, wherein the etching device comprises an etching mechanism and a second cleaning mechanism, the etching mechanism comprises an etching transmission segment and an etching assembly, the etching assembly is used for spraying an etching liquid to a circuit board on the etching transmission segment, the etching transmission segment comprises two rows of etching transmission rollers arranged in parallel, and a plurality of liquid absorption holes are arranged on the etching transmission rollers and used for generating negative pressure and absorbing the etching liquid on the circuit board. In the automatic etching device, by arranging the board feeding device, the developing device, the first inspection device, the etching device, the second inspection device, the bulking device, the membrane retreat device and the board out-coming device, the etching operation of the whole circuit board can be completed, the etching efficiency is relatively high, and the automatic degree is relatively high. Moreover, by arranging the plurality of liquid absorption holes on the etching transmission rollers, the etching quality of the circuit board can be improved.
Description
technical field [0001] The invention relates to the technical field of circuit board etching, in particular to an automatic etching equipment. Background technique [0002] With the development of social economy and the continuous improvement of people's consumption level, the use of electronic equipment is becoming more and more extensive. At this stage, the circuit board in electronic equipment is an extremely important part. Therefore, in order to better control the circuit The surface of the board is processed, and a large number of printed circuit board production and processing devices have appeared in the society. [0003] Usually, the circuit board needs to go through many processes in the manufacturing process before it can be prepared into a finished product. Among them, the etching process of the circuit board is one of the most critical processes in the entire manufacturing process of the circuit board. The main purpose of the etching process is to form conducti...
