Suspended adsorption type automatic adhering device for indicating gratings

The invention discloses a suspended adsorption type automatic adhering device for indicating gratings, relates to the field of a grating ruler manufacturing process, and solves the problems of poor adhesive consistency, low yield and low measurement accuracy because the three-dimensional adjustment amount of the indicating gratings, the pressing force of carriages and the contractibility of glue water cannot be accurately controlled in the manual adhering process of the indicating grating in the conventional fixed-position adhering device for the indicating gratings. The device comprises a substrate, a hollow turntable, an electric rotating platform, a grating pickup assembly, a carriage positioning assembly, an adhesive dispensing and curing assembly, a two-gear zoom lens, an adjusting seat, and a suspended adsorption structure which is fixed on a third turntable of the electric rotating platform and is used for adsorbing the indicating grating, wherein the electric rotating platform, the grating pickup assembly, the carriage positioning assembly, the adhesive dispensing and curing assembly, the two-gear zoom lens and the adjusting seat are arranged in the hollow turntable and are fixed on the substrate; the indicating grating pickup assembly and the carriage positioning assembly are respectively positioned on two sides of the electric rotating platform; a plurality of indicating gratings and a plurality of carriages are uniformly distributed on the inner and outer circumferences of the hollow turntable respectively. The adhesive accuracy, the measurement accuracy and the yield are improved through full-automatic adhesion, and the adhesive consistency is better.
