Description

Technical Field

[0001] The utility model relates to the technical field of sample carriers, and in particular to a dual-light-path vacuum adsorption sample carrier. Background Art

[0002] In the field of optical research, the sample slides used for optical testing are generally similar to glass slides, placed horizontally on the microscope's object frame, and subjected to XYZ three-dimensional movement and position adjustment for observation. However, this form of measurement is often not suitable for testing in self-built optical systems. The light source of a self-assembled optical system propagates horizontally, and the sample to be tested needs to be perpendicular to the light path. Therefore, an adapted sample carrier that can vertically clamp the sample to be tested is required for testing. The object to be tested is generally fixed by physical clamping, such as physically clamping the sample to be tested with two parallel pieces, and then moving it into the light path. Relying on traditional clamps for clamping will cause unstable clamping and wear due to long-term use. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figures 1-6As shown, the dual-light path vacuum adsorption sample carrier described in the present invention includes a base 1 and a mounting base 2; a sample loading base 3 detachably connected to the base 1; an optical path partitioning platform 42 provided on the mounting base 2; a plurality of vacuum adsorption holes Ⅰ4 provided on the optical path partitioning platform 42; a plurality of vacuum adsorption holes Ⅱ41 provided at the same height as the plurality of vacuum adsorption holes Ⅰ4; a vacuum adsorption tube 6 fixed to the mounting base 2; an air groove 61 connected to the plurality of vacuum adsorption holes Ⅰ4 and the plurality of vacuum adsorption holes Ⅱ41; and the mounting base 2 The light hole setting block 62 is set on the light hole setting block 62, and the front end area of the light hole setting block 62 is larger than the rear end area. The front end surface of the light hole setting block 62 is the light outlet, and the rear end of the light hole setting block 62 is the light inlet. This arrangement is conducive to the transmission of light to the next optical element after passing through the sample slide. Multiple vacuum adsorption holes Ⅰ4 and vacuum adsorption apertures Ⅱ divided by the light path separation platform 42 can be used to adsorb sample slides to form the sample aperture to be tested. The aperture on the other side of the light path separation platform 42 is the blank control aperture, wherein the sample aperture to be tested is located on the multiple vacuum adsorption holes Ⅰ4, multiple Each vacuum adsorption hole I4 and multiple vacuum adsorption holes II41 are used to adsorb samples and can adsorb samples below 9g. For samples that need to test the transmittance, there is no need to take out the sample and use the blank control aperture. The vacuum adsorption tube 6 can be used to generate a vacuum effect by using an external suction device (such as an air pump). When air is sucked from the vacuum adsorption tube 6, the sample piece can be fixed more firmly, and there will be no wear during the removal and placement process. The aperture between the multiple vacuum adsorption holes I4 and the multiple vacuum adsorption holes II41 is the aperture of the sample to be tested, and the light path passes through the sample to be tested. The aperture is fixed on the sample, and the other slot is the blank control aperture. The light path passes through the blank control from the aperture. The blank control is empty and is used to test the state of the light path when there is no sample. By moving the translation stage, the light path passes through the blank control aperture and the aperture of the sample to be tested respectively, so that the transmittance and other optical information of the sample can be measured. This function does not require taking the sample, and the transmittance test can be achieved by operating the sample stage (basically, optical transmittance measurement is to measure the background light intensity without placing the sample first, and then put the sample on to measure. This method is very inconvenient and requires moving the sample stage).

[0022] Specifically, the device also includes a plurality of magnetic rings 5 fixed to the base 1; a plurality of matching magnetic rings 11 are provided on the sample loading base 3; a plurality of angle adjustment bolts 9 are connected to the bottom of the base 1 by threads; and two sample loading adjustment bolts 7 are provided between the mounting base 2 and the sample loading base 3, and the two sample loading adjustment bolts 7 are connected to the sample loading base 3 by threads; and a sample loading support bead 10 fixed to the sample loading base 3, which can support the sample loading bead 10, and can clamp the sample loading base 3 and the mounting base 2 when in use, which can effectively replace the traditional fixed clamp, simplifying The invention relates to an integrated device, and during use, the device can be supported by adjusting bolts 9 at multiple angles, and the base 1 and the mounting seat 2 can be quickly disassembled and installed. The sample carrier base 2 can absorb the sample carrier through negative pressure, and only the bottom surface 2 of the sample carrier is in contact with the base 1, so as to prevent the upper surface of the sample carrier from being damaged and affecting subsequent use, and will not contaminate the measured object on the sample carrier. It also includes a precision adjustment nut 71 arranged on the sample carrier adjustment bolt 7. The precision adjustment nut 71 is provided with a plurality of ribs, which can increase the rotation precision by determining the number of rotating ribs during use, thereby achieving a more precise adjustment effect.

[0023] Specifically, the multiple matching magnetic rings 11 correspond one-to-one with the multiple magnetic rings 5, so that the magnetic ring 5 can absorb the corresponding matching magnetic ring 11 to maintain the detachability between the base 1 and the sample loading base 3, and through the magnetic connection, the combination position can be made more precise, which is convenient for the assembly of the device. It can be fixed and taken out by magnetic attraction so that it can enter and exit the system. The three magnetic attractions can make it very convenient for the mounting base to enter and exit the system, and after it is placed, the position of the sample is almost the same as the position where it was placed last time. In this way, if the mounting base is taken out and then returned to its place during testing, the test point position before it was taken out can be found to be basically unchanged.

[0024] Specifically, the sample loading base 3 is provided with a plurality of spring connecting holes 8, and the mounting base 2 is provided with a plurality of spring mounting holes 9. The plurality of spring connecting holes 8 correspond one to one with the plurality of spring mounting holes 9 respectively. By screwing out or screwing in the adjustment bolts 9 at different positions, the tilt angle of the sample loading base on the mounting base can be adjusted in multiple directions, which is convenient for observation during the test.

[0025] Specifically, two tension springs 13 are respectively arranged between the multiple spring mounting holes 9 and the multiple spring connecting holes 8. The tension springs 13 can always maintain the closing force between the mounting seat 2 and the sample loading base 3, and can replace the traditional clamping tool to clamp the sample carrier, thereby simplifying the device.

[0026] Specifically, both ends of the two tension springs 13 are fixed with rivets 14, and multiple rivets 14 are respectively slidably connected to the mounting seat 2 and the sample loading base 3. Through the limiting effect of multiple rivets 14 and tension springs 13 on adjusting the mounting seat 2 and the sample loading base 3, the mounting seat 2 can always be in contact with the sample loading adjustment bolt 7, so that the two sample loading adjustment bolts 7 can push the mounting seat 2 to move when rotating, thereby adjusting the spacing between the clamped sample slides, thereby adapting to a variety of sample slides of different specifications.

[0027] Specifically, the two sample loading adjustment bolts 7 are both provided with a top ball 12. The provision of the top ball 12 can reduce the wear on the sample loading base 3 when adjusting the distance between the mounting seat 2 and the sample loading base 3, thereby increasing the service life of the device.
