Embodiment 1

[0048] A kind of production process of roof prism glued parts of the present embodiment, the operation steps are:

[0049] 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;

[0050] Step 2, processing of the fourth side 4: grinding and polishing the fourth side 4 of the roof prism wool;

[0051] Step 3, processing of the second surface 2; grinding and polishing the second surface 2 of the roof prism wool;

[0052] 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;

[0053] 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;

[0054] St...

Embodiment 2

[0059] 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

[0061] 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 roof prism glued piece production process and tooling thereof, belonging to the technical field of optical component production. The production process of a roof prism glued part of the present invention is through processing of the large surface and the third surface → processing of the fourth surface → processing of the second surface → coating processing → gluing → body fixing → processing of the roof surface → roof surface reprocessing. In the present invention, the large surface, the third surface, the fourth surface and the second surface are sequentially ground and polished in this order, and the opposite surface is processed sequentially, which is convenient to fix, and has high processing precision, without frequent replacement of the processing support body, and high processing efficiency ;The large surface and the second surface are protected with black paint after coating to prevent the film surface from being damaged during gluing; the third surface is glued and fixed with a support to ensure the processing consistency of the roof surface; The surface is subjected to secondary processing to ensure the processing accuracy of the roof ridge surface, and achieve the purpose of shortening the processing cycle, improving work efficiency, improving angle accuracy, reducing dimensional errors and improving product qualification rate.

Description

technical field [0001] The invention relates to the technical field of optical component production, in particular to a production process and tooling for roof prism glued parts. Background technique [0002] 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, a large number of reworked products will be caused due to the out-of-tolerance angle, which will increase the workload and cannot fully reflect the characteristics of efficient production. [0003] The traditional method of processing roof prism glued parts is to use the optical glue method. ...
