Problems solved by technology
A small amount of qualitative change will not have a great impact on the overall use of the ink, but there is only one outlet when the ink is pumped from the ink storage tank, and many variable components that cannot be filtered are easy to form enrichment near the outlet
There are local differences in the coating process, often the coating thickness of the corresponding area of the discharge port is thicker, and the quality is poor, resulting in low uniformity of ink coating, reducing the resolution of the film, and the production line precision

Embodiment Construction
[0022] figure 1 It is a schematic diagram of the overall structure of the coating machine glue supply system in the prior art; figure 2 It is a schematic diagram of the side structure of the coating machine glue supply system in the prior art. like figure 1 or figure 2 As shown, the coating machine glue supply system in the prior art includes coating ink 1, coating machine discharge port 2, coating tank baffle plate 3, conveying roller 4, coating roller 5, coating tank 10, in addition, figure 2 The 6 in represents the copper clad laminate. based on figure 1 or figure 2 In the glue supply system of the coating machine shown, most of the ink circulates continuously during the process of ink storage tank→coating tank→coating→excess ink is backed up→ink storage tank. During this process, the ink is constantly in contact with the outside world, its solvent is continuously volatilized, and the components will inevitably undergo some qualitative changes. A small amount of ...

The embodiment of the invention provides a glue supplying system for a coating machine. The method includes a plurality of discharging ports, coating groove baffles, conveying rollers, coating rollers, coating grooves and homogeneous rollers; the coating groove on one side is provided with the plurality of discharging ports, and the discharging ports on the coating grooves on the two sides are symmetrically distributed; the homogeneous rollers are arranged in the coating grooves below the discharging ports; and the homogeneous rollers and the coating groove baffles form a film coating groove.According to the embodiment of the invention, due to the design of the plurality of discharging ports, printing ink is uniformly conveyed to different coating positions, it is fully guaranteed that variable components or impurities which cannot be filtered and is generated in the circulating process of the printing ink can be dispersed to more areas, enriching of the variable components or impurities in a single area is reduced, and the film coating uniformity and quality can be improved. Due to the homogeneous rollers, the variable components and part of solvent evaporation in the printing ink are mixed again with a printing ink body, uniform dispersion of the printing ink is achieved, uniformity of film coating in a local area is further improved, and the film coating resolution and thecircuit manufacturing precision are improved.
Description
technical field [0001] The embodiments of the present invention relate to the field of coating technology, in particular to a coating machine glue supply system. Background technique [0002] Nowadays, the development of high-frequency and high-speed lines is changing with each passing day. From 1G, 2G, 4G, 10G to 25G in the future, the upgrading of products also puts forward higher requirements for the accuracy of line production. At the same time, the accuracy of line production also directly affects printed circuit board (Printed Circuit Board) , referred to as PCB) the capability level of the final product. How to improve the manufacturing accuracy of the circuit has become an urgent problem to be solved in the PCB industry. Tracing back to the source, to improve the accuracy of circuit manufacturing is mainly to improve the resolution of the coating (dry film or coating ink). The resolution is affected by two factors, one is the quality of coating, and the other is th...
