Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific operation steps.
[0037] see Figure 1 to Figure 5 As shown, the method of the present invention mainly includes the preparation of the protective film material, the preparation of the protective film, pre-curing, roll alignment, filling of the protective film material, and complete curing. Among them, the preparation process of the protective film film adopts the feeding and feeding transmission mechanism and the tension control mechanism in the printing machine. Rolling filling protective film is an important link, mainly including pressure control, speed control, roll alignment and roll pressure creation of partial vacuum. The pressure is controlled by the air pressure valve, and the position of the grating scale and the protective film is calibrated by the linear infrared transmitter, and the local negative pressure is formed by the vacuum pump.

Abstract
The invention discloses a method for coating a protective film on a grating scale for machine tool measurement. According to the method, a protective film is coated on a transfer film in a roll coating manner, a scraper is used for controlling thickness, the uniformity of the protective film is controlled by a tension force, the protective film on the transfer film is pre-solidified to improve the viscosity of the protective film so that the protective film can be filled in a grating line groove conveniently; then the protectively film and the surface of the grating scale are adhered together in a rolling manner and the protective film is filled in the grating line groove. Before rolled lines contact a part to be contacted, pressure surrounding the part to be contacted is reduced by a vacuum pump so that the protective film is filled conveniently; after the protective film is filled, the grating scale with transferred protective film is completely exposed to ensure that the structure of the protective film is fixed; and finally the transferred film is stripped off. The method disclosed by the invention has the advantages of high efficiency, low cost and capability of continuous transfer and the like.
Description
【Technical field】 [0001] The invention relates to the field of protective film coating, in particular to a method for coating a protective film of a grating ruler for machine tool measurement. 【Background technique】 [0002] Since the 1950s, research institutions in various countries have been engaged in the research of precision position detection and developed a new generation of detection components and measurement methods. The importance of precision position detection technology is becoming more and more significant, and it has been widely used in the fields of aerospace and ship engineering, biomedicine and health engineering, microelectronics processing, and precision mechanical instruments for many years. The working principle of grating measurement is based on the formation principle of physical moiré fringes. Grating measurement is usually used in digital detection systems to detect high-precision linear displacement and angular displacement. It is a detection dev...
