Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] The technical scheme that the present invention solves its technical problem adopts is: the microstructure press-fit prism assembly method that is used for PMMA polymer material, comprises the following steps:

[0026] (1) On the bottom surface of the PMMA pressing prism, the glass plate is welded by ultrasonic welding technology, so that the bottom surface of the PMMA pressing prism is fixed on the glass plate;

[0027] (2) Use a diamond cutting machine to cut out the glass plate that has fixed the PMMA pressed prism, and the free boundary needs to exceed the outline of the PMMA pressed prism;

[0028] (3) Etch the same assembly line as the outline of the glass plate on the inner layer of the lens of the ordinary spherical mirror that needs to be installed;

[0029] (4) The PMMA pressed triangular prism microstructure layer is aligned with the inner layer of t...

Abstract

The invention relates to an assembly method of a microstructure pressing triple prism made from PMMA polymer material. The method comprises the following steps: welding a flat glass plate on the bottom surface of a PMMA pressing triple prism by an ultrasonic welding technology to enable the bottom surface of the PMMA pressing triple prism to be fixed on the flat glass plate; cutting the flat glass plate fixed on the PMMA pressing triple prism by a diamond cutting machine, wherein a free boundary exceeds the outline of the PMMA pressing triple prism; etching an assembly line on the inner layer of a lens of a common spherical mirror needing to be installed, wherein the assembly line is the same as the contour line of the flat glass plate; aligning a microstructure morphology layer of the PMMA pressing triple prism to the inner layer of the common spherical mirror, and welding the flat glass plate provided with the PMMA pressing triple prism on the assembly line by an ultrasonic welding technology; and carrying out edge polishing treatment.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an assembly method of a PMMA polymer material microstructure press-attached prism used for strabismus correction. Background technique [0002] In recent years, with the development of material science and the progress of material manufacturing technology, press-fit prisms have begun to be used in the auxiliary treatment of children's strabismus. It consists of a group of Fresnel microstructure prisms neatly arranged to control the refraction of incident light. Reports from a number of medical institutions have shown that press-fit prisms have achieved good clinical therapeutic effects in the adjuvant treatment of implicit strabismus, common strabismus, and paralytic strabismus. The pressed prism has the outstanding advantages of light weight, thin lens, beautiful and comfortable, and can replace the traditional glass prism. [0003] At present, the pressure-bonded prisms circula...
