Description

Technical Field

[0001] This invention relates to the field of screen printing machine technology, and specifically to an easy-to-clean, oil-resistant coating structure for PC boards. Background Technology

[0002] The squeegee of a screen printing machine is mainly made of materials such as natural rubber, synthetic rubber, and polyurethane rubber. The squeegee plays a crucial role in the printing process, directly contacting various inks and solvents. Therefore, it needs to possess high wear resistance and a certain degree of hardness. To meet these requirements, the main materials used to make squeegees include natural rubber, synthetic rubber, and, in some applications, polyurethane rubber. This material selection ensures that the squeegee can effectively transfer ink during printing while maintaining sufficient durability for long-term use.

[0003] During the screen printing process, ink is prone to emulsification and adhesion to the squeegee surface due to temperature changes or impurities. The existing squeegee structure is not convenient for cleaning oil stains and for squeegee maintenance, and there is still room for improvement in its practicality. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-clean, oil-resistant coating structure for PC boards, in order to solve the technical problems in the prior art where ink easily emulsifies and adheres to the scraper surface, and the existing scraper structure is not convenient for cleaning oil stains and maintaining the scraper.

[0045] Inner support component 1 and inner support component 6 are made of metal, while sheet metal components 2 and 5 are made of plastic. Sheet metal components 2 and 5 are injection molded onto inner support components 1 and 2 respectively using a plastic-coated iron process. This improves the overall structural strength of the PC board, enhances the reliability of the device, and reduces the assembly difficulty, saving labor costs during assembly. Connector 3 connects the upper and lower parts. Designing connector 3 independently from sheet metal components 2 and 2 reduces the mold opening costs for sheet metal components 2 and 2, lowering production costs. To reduce manufacturing costs, during use, ink is applied by scraping through the contact between the plate component 2 5 and the screen. The outer end face of the plate body 2 51 is coated with an oleophobic coating 55, which effectively prevents ink from adhering to the surface and prevents ink emulsification, facilitating cleaning. When cleaning is required, the plate component 2 5 and the inner support component 2 6 can be removed as a whole by unscrewing the screw 4, making it easy to clean and maintain the scraper structure. The connecting plate 1 17 and the connecting plate 2 63 are wrapped by the connector 3. At the same time, two side baffles 54 are respectively set on both sides of the lower limit plate 15 and the mounting plate 61, which can fully wrap the metal parts to prevent ink from contacting the metal parts and ensure the service life of the device.

[0046] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
