Compressing device in solidification process of glue for main grating glass ruler and ruler shell of grating ruler

Abstract

The invention discloses a compressing device in the solidification process of glue for a main grating glass ruler and a ruler shell of a grating ruler, and belongs to the technical field of photoelectric measurement. The compressing device aims to solve the problems that in the prior art, the relative positions of the glass ruler and the ruler shell are hard to control accurately, the bonding strength of a glue layer is influenced, and compressing is uneven. The compressing device comprises a wave spring, a tensioning mechanism, guide rails and a fixed structure. One end of the wave spring is hung on the fixed structure, the other end of the wave spring is connected with the tensioning mechanism through a movable connecting rod, the ruler shell moves along the guide rails, and the wave spring is made to be completely located in the corresponding clearance of the ruler shell and the glass ruler. The wave spring is tensioned and loosened through the tensioning mechanism, and then the ruler shell and the glass ruler are compressed and loosened. The glass ruler and the ruler shell are evenly compressed through the wave spring, and in the place-in and take-out process of the spring, the relative positions of the glass ruler and the ruler shell can be accurate, and the bonding strength of the glue layer is guaranteed. Bonding reliability and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and in particular relates to a pressing device in the process of gluing and curing the main grating glass ruler of the grating ruler and the ruler shell. Background technique [0002] There are many ways to install and fix the main grating glass scale and the scale housing in the grating scale. The most common and reasonable way is to bond the glass scale and the scale housing together with special glue. In this gluing process, it takes a certain amount of time for the glue to cure, usually more than 24 hours. During this period of curing, in order to ensure that the relative position and bonding of the glass ruler and the ruler housing are compact, the glass ruler and the ruler housing need to be kept in a compressed state. [0003] The traditional way to maintain this kind of compression during the glue curing process is to use a small V-shaped spring. After dispensing glue, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to propose a pressing device in the process of gluing and curing the main grating glass ruler of the grating scale and the scale shell, so as to solve the problem in the prior art that the relative position of the glass scale and the scale shell is not easy to accurately control during the external force pressing process And the withdrawal of external force affects the adhesive strength of the colloidal layer and the problem of uneven compaction and compaction during the compaction process. The operation is simple and the efficiency is high.
