Abstract

The utility model discloses a limit clamp applied to optical component plywood preparation. The limit clamp applied to optical component plywood preparation comprises a splint (1) with an inner hole, at least two support plates (2) fixed at the lower part of the splint (1). The inner hole of the splint is matched with the size of an optical component. The optical component can be placed in the inner hole of the splint and does not move under the limiting of the inner hole. When gluing is carried out, the inner hole of the limit clamp is used to position and limit the position of the optical component, and relative displacement is not generated between gluing parts, thus the quality of a product is improved.

Description

Be used for the limit clamp that the optical element scale board is made

Technical field

The utility model relates to the device of making optical element, especially relates to a kind of limit clamp for the making of optical element scale board.

Background technology

In order to make optical system that good picture element be arranged, object lens, eyepiece and other system form by two or more than two lens, and prism and graduation part also adopt array mode for easily manufactured with shielding.The mode of combination comprises glue-line gummed commonly used and the combination of separate type microscope base, in particular cases also uses the light glue glued adhesion.The gummed of optical element is with two or two above optical elements glued joint with optics or with ways such as optical cements, the technological process that is connected together by certain technical battery.Light-sensitive emulsion was flowable before solidifying, and when gummed, if the position of part is not had alignment restrictions, might produce relative displacement between the two gummed parts, thereby affect product quality.

CN202067011U discloses a kind of centering clamp for special-shaped optical lens gluing, combined by patrix and counterdie, the holder of fixing the first eyeglass is set in the patrix, the fixed area of fixing the second eyeglass is set in the counterdie, yet, still might slide between the upper and lower mould, affect the gummed between the optical element.

The utility model content

In order to overcome the defective of prior art, the utility model provides a kind of limit clamp of making for the optical element scale board, can limit in the optical veneering process between two or the polylith optical element and mutually slide.

In order to solve the problems of the technologies described above, the limit clamp that is used for the making of optical element scale board that the utility model provides comprises the clamping plate with an endoporus; Be fixed at least two back up pads of described clamping plate bottom, the endoporus of described clamping plate and the size of described optical element are complementary, and optical element can be inserted in the endoporus of described clamping plate and is not moved under the position-limiting action of endoporus.

Further, the thickness of the clamping plate of the described limit clamp of making for the optical element scale board greater than the thickness of an optical element to be glued together less than the gross thickness of the optical element stack to be glued together of two or more than two composition.

Further, the part of the back up pad of the described limit clamp of making for the optical element scale board stretches into the below of described clamping plate endoporus.

The beneficial effect that the utility model brings: the technical scheme that the utility model provides, in when gummed, the endoporus by limit clamp positions restriction to optical element, makes between the gummed part and does not produce relative displacement, thereby improve the quality of products.In the preferred version, the part of back up pad stretches into the below of described clamping plate endoporus, and the below of optical element plate to be glued together is all unsettled, in light-sensitive emulsion levelling process, is beneficial to and adds the heavy burden briquetting and flatten.

Description of drawings

Accompanying drawing is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation of embodiment limit clamp;

Fig. 2 is the right TV structure synoptic diagram of Fig. 1.

Embodiment

Fig. 1, shown in Figure 2 be used for the limit clamp that the optical element scale board is made, bottom at the clamping plate 1 of endoporus is fixed with four back up pads 2, the part of back up pad 2 stretches into the below of clamping plate 1 endoporus, the thickness that the thickness of clamping plate 1 superposes less than the optical element to be glued together of two or more than two composition greater than the thickness of an optical element to be glued together, the endoporus of clamping plate and the size of described optical element are complementary, and optical element can be inserted in the endoporus of described clamping plate and is not moved under the position-limiting action of endoporus.

During gummed, the first optical element to be glued together is inserted in the endoporus of the limit clamp clamping plate 1 of making for the optical element scale board, coat light-sensitive emulsion, cover second optical element to be glued together, add and carry out light-sensitive emulsion after the heavy burden briquetting flattens and close.

Obviously, the utility model is not limited to above preferred implementation, also can be in the spirit of the utility model claim and instructions restriction, carry out conversion and the improvement of various ways, can solve same technical matters, and obtain the technique effect of expection, so do not repeat.Those of ordinary skill in the art can be from the disclosed content of the utility model directly or all schemes of associating, as long as within the spirit that claim limits, also belong to protection domain of the present utility model.
