Embodiment 1

[0046] Such as Figure 2-Figure 5 As shown, the jig for prism bonding includes a support frame 20 . The supporting frame 20 is provided with an accommodating groove 21 for supporting the prism. The accommodating groove 21 is a Y-shaped groove. A first guide rail 31 is respectively provided on two lateral sides of the support frame 20 . A first sliding block 32 is respectively arranged on the two first guide rails 31 . The first slider 32 is slidably disposed on the first guide rail 31 . The first slider 32 can be close to the support frame 20 or away from the support frame 20 . A glue guide groove 33 is disposed on the first slider 32 . The glue guide groove 33 is located at the same height as the glued surfaces of the two rectangular prisms. The first slider 32 is made of a material that can be attracted by magnetic force. A first magnetic block 61 is respectively arranged on the left and right sides of the support frame 20 . The first magnetic block 61 can attract th...

Embodiment 2

[0052] Such as Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the accommodating groove 21 is a V-shaped groove. All the other structures and methods of use are the same as in Example 1.

Abstract

The invention discloses a tool for gluing prisms. The tool for gluing prisms is characterized by comprising a support frame, wherein the support frame is provided with an accommodating groove for supporting the prisms; the two transverse sides of the support frame are respectively provided with first sliders capable of moving close to or away from the direction of the support frame; and the two longitudinal sides of the support frame are respectively provided with a stop block and a second slider capable of moving along the direction of a dovetail groove. The tool is simple in structure and convenient to use, and can be used as a replacement for human hands to realize accurate positioning of two rectangular prisms. By adopting the tool, the prisms can be glued without the influence of the skills of operators, the working efficiency can be remarkably improved by multiple folds compared with the traditional gluing method, the yield is greatly improved and is as high as 99%, and the effect is more remarkable when the prisms having a right-angle side greater than 20mm are glued.

Description

technical field [0001] The invention relates to a jig for prism bonding. Background technique [0002] The beam splitting prism is one of the necessary components in optical instruments. Such as figure 1 The dichroic prism 10 shown is a cube or a cuboid that is glued together by a first right-angle prism 101 and a second right-angle prism 102 . Dichroic films with various functions are coated on the glued surface of two rectangular prisms or one of them. The spectroscopic film plays the role of energy splitting, polarization splitting or depolarization splitting in optical instruments. Schematic diagram of a beam splitting prism figure 1 shown. [0003] In the use of optical instruments, the surface shape, angular precision, smoothness and stress of the cemented prism must be strictly controlled and meet the required requirements. For larger-sized prisms, such as prisms with a side length of more than 20 mm, if the glued surface is perpendicular to the horizontal plane...
