Description

Scanner mirrors sheet assembling anchor clamps

Technical field

The utility model relates to a kind of special tooling anchor clamps in the scanner assembling, is specifically related to the clip assembling specific purpose tool of optical reflecting lens in the scanner head light path.Described reflecting optics specifically refers to rise in the light path eyeglass of reflex, to play the lens wearer of transmission effect in the difference light path.

Background technology

Scanner is when carrying out scan task, scanner head moves along certain major axis guide frame and finishes scan task, and scanner head cooperates with charge-coupled device (CCD/B) by certain light path and will be scanned picture or manuscript converts computer graphics metafile in scanning process.In the above-mentioned light path except camera lens and mainly constitute by one group of reflecting optics, these reflecting optics utilize the optical reflection principle will scan the image that obtains by certain light path arrangement and send into charge-coupled device by camera lens.For position and the angle of each reflecting optics of accuracy in light path that guarantee light path is that calculated in advance is good, reflecting optics is generally formed by a transparent glass sheet coating reflection horizon, on the relevant position of scanner head support body (chassis), penetrate locating surface is arranged, flexible mounting board (clip) clip that the two ends of reflecting optics adopt the specific alloy material to make is fixed on the locating surface, makes reflecting optics be in the tram.In the prior art, for reflecting optics all employing manual operationss are installed, but practice shows that there are many shortcomings in this mode, specifically embody a concentrated expression of the following aspects: 1, interference from human factor hand-manipulated is more, cause bearing accuracy and consistance bad, even often block not in place or make eyeglass distortion; 2, because installing space is less, the assembling of eyeglass is cumbersome, and inconvenient operation; 3, not only work efficiency is low for manual installation eyeglass, and hinders hand easily.

The purpose of this utility model provides a kind of mechanized tool that the scanner head reflecting optics is installed that is exclusively used in, and to overcome above-mentioned deficiency, replaces manual fitting operation.

Summary of the invention

For achieving the above object, the technical solution adopted in the utility model is: a kind of scanner mirrors sheet assembling anchor clamps, its content is: vertically set up at least two guide pillars on a base plate, the base plate top is provided with a slide plate, slide plate slides up and down with guide pillar and is connected, be set with spring on the guide pillar between slide plate and the base plate, constitute the relative base plate of slide plate in Elastic Sliding mechanism longitudinally with this; A pair of slide block is set on the slide plate, and this a pair of slide block is symmetrically arranged and laterally is slidingly connected with slide plate; Be provided with spring between two slide blocks, the bottom lateral surface of each slide block is provided with the inclined-plane, and two inclined-plane left-right symmetric also contact with two pulleys respectively, and two pulleys are bearing on the base plate respectively; The top of two slide blocks is respectively equipped with a jaw, and two jaws constitute a pair of clip structure; Also be provided with location structure on the slide plate, this location structure and a pair of jaw and scanner head support body and clamp the position and be complementary at the scanner head support body.

The related content of technique scheme is explained as follows:

1, in the such scheme, described " base plate " also can be called base, underframe, substrate, substrate, support, a platform etc., and it is from being a kind of foundation support body in essence.Described " vertically " is meant the short transverse or the guide pillar vertical direction of anchor clamps.Described " laterally " is meant the direction of motion of the relative slide plate of jaw or the left and right directions among Fig. 3.

2, in the such scheme, described " at least two guide pillars " goes out to send definite from necessary condition, in fact for base plate and slide plate, considers that the stability that slides up and down adopts three guide pillars better, and adopts four guide pillar the bests.

3, in the such scheme, the inclined-plane on the lateral surface of described slide block bottom has directivity, forms back taper by two inclined-planes shown in Figure 3.

4, in the such scheme, be when eyeglass is installed, the relative jaw of scanner head support body to be positioned in the effect that scanner head support body location structure is set on the slide plate.

5, in the such scheme, when eyeglass is installed, carry mounting board, on each jaw, be provided with the concave port that to place the eyeglass mounting board, establish magnet in this concave port in order to make jaw.

6, in the such scheme, described slide block and slide plate laterally are slidingly connected and can adopt following structure to realize: laterally offer a long slot bore on slide plate, two slide blocks place long slot bore, the Lower Half of slide block is positioned at below the long slot bore, and the first half is positioned at more than the elongated slot, establishes a guide rod on the position parallel with long slot bore, these guide rod two ends are fixed on the slide plate, set slide opening on two slide blocks is passed at the middle part, constitutes laterally with this to be slidingly matched, and spring housing is contained on two guide rods between the slide block.

7, in the such scheme, described two pulleys are bearing on the fixed block respectively, and fixed block is fixed on the base plate.

The utility model principle of work is: referring to shown in Figure 3, earlier two mounting boards are placed on respectively in the concave port of jaw before reflecting optics is installed, magnet holds mounting board and is the relative fixed state.A reflecting optics that will be mounted then is placed on the locating surface of scanner head support body ejaculation, then the scanner head support body is positioned on the slide plate, and this moment, the scanner head support body cooperated with location structure, and jaw carries mounting board and stretches into the appropriate location from two ends respectively.Next holding scanner head pushes downwards, scanner head with slide plate in lower slider, drive two slide blocks and move downward, because the interaction of inclined-plane and pulley, two slide blocks are drawn close when moving downward mutually, and final two mounting boards are clamped to eyeglass on the locating surface of scanner head support body.When loosing one's grip since the thrust of guide pillar spring slide plate is upwards lifted, simultaneously on the slide plate laterally the spring in the slide mechanism two jaws are pushed open because mounting board clamping friction force is greater than magnetic pull, jaw and mounting board disengaging when resetting with rear slider.

Here need to prove: the only suitable situation of mounting board being installed relatively of technique scheme from the eyeglass two ends, inapplicable for the fixed form that mounting board is installed from eyeglass one side.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, the utility model utilizes two cover slide mechanisms to constitute a kind of with ejector half mounting board installing mechanism in the space, adopt this mechanism that eyeglass is installed and exempted the interference of human factor hand-manipulated, lens orientation precision height, high conformity makes that eyeglass is stressed in installation process more to become reasonable.

2, the mechanicalness erecting tools of the utility model effect eyeglass has replaced original manual mounting means, its high efficiency, and easy and simple to handle, installation quality is good.
