Embodiment 1

[0054] A kind of production process of roof prism glued parts of the present embodiment, the operation steps are:

[0055] Step 1, processing of the large surface 1 and the third surface 3: grinding and polishing the large surface 1 and the third surface 3 of the roof prism wool;

[0056] Step 2, processing of the fourth side 4: grinding and polishing the fourth side 4 of the roof prism wool;

[0057] Step 3, processing of the second surface 2; grinding and polishing the second surface 2 of the roof prism wool;

[0058] Step 4, coating processing: use a vacuum coating machine to coat the large surface 1 with an anti-reflective coating, and the second surface 2 with a reflective coating, and add black paint for protection to obtain a single piece of semi-finished product;

[0059] Step five, gluing: After cleaning the third surface 3, glue the third surface 3 of the two semi-finished products together with optical special glue to form a Figure 4 glued parts shown;

[0060] ...

Embodiment 2

[0065] A kind of production process of roof prism glued parts of the present embodiment, the specific steps are basically the same as embodiment 1, the improvement is: after step 1 is processed, the parallelism of the two sides of the large surface 1 and the third surface 3 is controlled within 15 ", and the size The error is within ±0.01mm; after step 2 processing, the 90° angle between the large surface 1 and the fourth surface 4 is within ±10"; after step 3 processing, the edge difference is within 15", the large surface 1 and the second surface The error of the included angle between the two is within 15", and the error of the total length is within 0.02mm; the components and proportions of the black paint described in step 3 are the main agent: hardener: thinner = 8:1:7; glue in step 5 The adhesive layer of the piece has no bubbles and is not clean. Use a 15-second goniometer to control the parallelism between the two sides 1 within 10", and check the two fourth sides 4 wi...

Embodiment 3

[0067] A kind of roof prism glued piece production process of this embodiment, the specific steps are the same as embodiment 2, and the improvement is: in the step 5, it is carried out in the glued piece tooling 10, which can ensure the consistency and accuracy of product processing; In step 6, a glue groove is provided in the middle of the 45° body 16 large surface of the tooling to avoid overflow of glue and affect the working and processing surface of the body and workpiece. Such as image 3 As shown, step five glued tooling 10 includes a base 11 and a limit block 12. The specific use steps are: glue the large surface 1 of a single semi-finished product on the base 11, and stick the side 5 to the limit block 12. The surface of the third surface 3 is coated with optical special glue, and the third surface 3 of another single semi-finished product is facing downward, and the side 5 is facing the limit block 12. Push gently on the surface of the third surface 3 of the previous...

Abstract

The invention discloses a fixture for roof prism gluing part production, and belongs to the technical field of optical component production. The fixture for roof prism gluing part production comprises a base, two limit blocks, three square flat plates, a 45-degree rest and a square brick. Glue grooves are formed in the middles of the limit blocks, a glue groove is formed in the middle of a large surface of the 45-degree rest, the square brick has a 90-degree angle, angular accuracy is within 1', the two limit blocks are vertically used, the three square flat plates are placed among the two limit blocks and the base and between a semi-finished product and the base, the surface evenness of the base is lambda / 4, the finish degree of the base is second level, accuracy of the 90-degree angle of the limit blocks is within 30', and the tolerance of the square flat plates is + / -0.01mm. Processing accuracy of a roof ridge surface is ensured, processing cycle is shortened, working efficiency and angular accuracy are improved, dimensional errors are decreased, and product qualification ratio is increased.

Description

[0001] The application of the present invention is a divisional application, the application number of the parent application: 2016105790034; the name of the parent application: a production process and tooling of roof prism glued parts; the application date of the parent application: 2016-7-21. technical field [0002] The invention relates to the technical field of optical component production, in particular to a tooling for the production of roof prism glued parts. Background technique [0003] How to ensure the angular accuracy of the prism in the mass production process is a core problem that must be solved in every process technology solution. Because each process in the manufacturing process may affect the angular accuracy, the control of the angular accuracy runs through the entire manufacturing process, and it also requires a solution to the influencing factors of each process. If this problem cannot be solved well, even with the most advanced processing equipment, ...
