Problems solved by technology

However, in actual production, this problem cannot be solved well. The main reason is that in the development process, even for the same substrate, the degree of development of different parts is difficult to achieve consistency due to various internal and external factors.

Embodiment Construction

[0014] The following embodiments will discuss the structure of a horizontal single-sided developing machine in the upper spray mode of the present invention. Of course, the present invention can also be used in double-sided developing machines. It should be understood that the following examples are for the purpose of illustration only, rather than limiting the protection scope of the present invention, so all applications that can be obtained through simple transformations fall within the protection scope of the present invention.

[0015] The invention provides a contactless transmission device. Such as figure 1 As shown in FIG. 1 , it shows a schematic diagram of a transfer device for transferring substrates according to an embodiment of the present invention, and the device includes several constituent units 11 with the same structure. figure 2 Shown is an enlarged schematic diagram of a component unit 11 and one end of the component unit 11 of the conveying device acco...

Abstract

The invention discloses a non-contact conveying device used in a developing machine. The device comprises a plurality of component units including: rolling shafts, a plurality of rollers sleeved on the rolling shafts, and gears fixed on the ends of the rolling shafts. The rollers are divided into two groups, and are respectively fixed near the two ends of each rolling shaft. With the non-contact conveying device provided by the invention, the possibility of dry film falling caused by the contact between the dry film and the rollers during conveying is avoided. Also, with the non-contact design, sprayed developing liquid is prevented from phenomena such as non-uniform spraying and inconstant pressure caused by the blockage of the rollers.

Description

[0001] technical field [0002] The invention relates to a developing machine assembly, in particular to a non-contact conveying device for the developing machine. Background technique [0003] In the process of PCB board or PCB mask board processing, a developing machine is needed. The main function of the developing machine is to reveal the exposed graphic area, so as to proceed to the next step. As an important link, the quality of development has a great influence on the quality of the final product. The problems that are prone to occur in traditional development are mainly underdevelopment or overdevelopment. People have always hoped to reduce the occurrence of these problems by controlling some parameters. However, in actual production, this problem cannot be solved well. The main reason is that in the development process, even for the same substrate, the degree of development of different parts is difficult to achieve consistency due to the influence of various inter...
