Abstract

[0002] The optical detection instrument is in a non-contact state with the sample, suitable for detecting fragile or sensitive materials. It uses the reflection and refraction of the optical path to achieve fine penetration detection of the sample, can detect the thickness and smoothness of the sample. When detecting, its detection method is to emit rays downward at a certain angle, and analyze the smoothness of the plane through the reflection of the rays.

During the movement, it is easy to cause the lens sample to move and vibrate, which will easily cause deviation in the moving detection process. Moreover, during the detection process, it cannot be ensured that the lens sample is in a horizontal state. When there is dust on the plane where the lens sample is placed, it is easy to cause a small inclination at the bottom of the lens sample to be blocked by the dust during placement, thus affecting the detection result.

Embodiment
[0020] Please refer to Figures 1-5, the present utility model provides a device for optical detection of samples, and its structure includes a cabinet 1, a detection table 2, a mechanical table 3, an analyzer 4, and a base 5. The detection table 2 is installed at the upper end of the cabinet 1, the cabinet 1 is fixedly embedded at the upper end of the base 5, the mechanical table 3 is installed at the upper end of the cabinet 1, the analyzer 4 is fixedly embedded at the upper end of the mechanical table 3, the detection table 2 is located directly below the analyzer 4. The detection table 2 is provided with a hydraulic device 21, a fixing structure 22, a horizontal plate 23, and a support structure 24. The hydraulic device 21 is fixedly embedded inside a fixed table 25, the horizontal plate 23 is fixedly embedded at the upper right end of the hydraulic device 21, the lower end of the horizontal plate 23 is in sliding fit with the upper-end track of the fixed table 25, the support structure 24 is fixedly embedded inside the middle of the horizontal plate 23, the fixing structure 22 is installed at the upper end of the horizontal plate 23, the fixed table 25 is installed at the upper end of the cabinet 1, the hydraulic device 21 is electrically connected to the internal circuit of the cabinet 1. A ray emitter is provided at the lower end of the side of the mechanical table 3, and the ray emitter is electrically connected to the analyzer 4. Thus, the lens sample is placed on the surface of the support structure 24, and the fixing structure 22 is pulled to squeeze the upper surface of the lens, so that the lens forms a fixing effect with upward support in the middle and downward pressing at the outer end. Thus, the ray emitter at the lower end of the mechanical table 3 emits rays towards the position of the detection table 2 below, and then the hydraulic device 21 inside the cabinet 1 is controlled to expand and contract, driving the horizontal plate 23 to move horizontally on the upper end of the fixed table 25 to perform translational detection on the lens sample.
[0021] As a further optimization of this technical solution, the support structure 24 is provided with a rubber block w1, a support rod w2, a triangular block w3, and a spring rod w4. The triangular block w3 is fixedly embedded at the upper end of the support rod w2, the spring rod w4 is attached inside the support rod w2, the rubber block w1 is clamped inside the spring rod w4, the upper and lower ends of the rubber block w1 are fixedly embedded inside the support rod w2, the support rod w2 is fixedly embedded inside the middle of the horizontal plate 23. There are six triangular blocks w3, which are evenly distributed in a ring, and the triangular blocks w3 are in an outwardly inclined state, with an inclination of 45 degrees. Thus, the bottom of the lens sample contacts the vertex of the triangular block w3. Under the support of the six triangular blocks w3, the support rod w2 generates vertical elasticity upward through the spring rod w4. Furthermore, under the elastic force of the rubber block w1, the upper end of the triangular block w3 squeezes the bottom of the lens sample to maintain a line-contact state at the top of the triangular block w3, preventing easy sliding during contact, avoiding excessive contact area that may cause dust particles to create gaps on the contact surface and tilt, and preventing the influence on the horizontal state of the lens sample.
[0022] The fixed structure 22 is provided with a force-bearing block t1, a spring t2, a transmission plate t3, and a limit plate t4. The lower end of the spring t2 is fixedly embedded in the upper end of the limit plate t4, and the upper end of the spring t2 is fixedly embedded in the lower right side of the transmission plate t3. The upper end of the force-bearing block t1 is installed at the lower left side of the transmission plate t3, and the lower end of the limit plate t4 is installed on the upper end of the horizontal plate 23. There are eight force-bearing blocks t1, which are evenly distributed in a ring centered on the support structure 24. Thus, according to the diameter of the lens sample, the circular rod on the side of the limit plate t4 moves outward on the track plate to adjust the width, and then the transmission plate t3 is pulled. After releasing the transmission plate t3 under the elastic force of the spring t2, it is pressed downward, so that the force-bearing block t1 generates extrusion on the upper surface of the lens sample, and further generates extrusion on the upper side of the outer end of the lens sample, forming a mutual support effect with the support of the middle support structure 24 of the lens sample, thereby realizing the effect of fixing the lens sample and preventing the lens sample from vibrating when the horizontal plate 23 moves.
[0023] The force-bearing block t1 is provided with a seesaw t11, a rotating rod t12, an elastic plate t13, and a connecting plate t14. The rotating rod t12 is fixedly embedded in the lower end of the connecting plate t14, the elastic plate t13 is attached to the lower end of the connecting plate t14, the elastic plate t13 is fixedly embedded in the inner side of the seesaw t11, the lower end of the rotating rod t12 is installed on the inner side of the seesaw t11, the upper end of the connecting plate t14 is installed at the lower left side of the transmission plate t3. The outer surface of the seesaw t11 is provided with a rubber material layer, which has the characteristic of large friction. The elastic plate t13 is made of rubber material and has the characteristics of large elasticity and strong tensile deformation force. Thus, the lower top end of the seesaw t11 contacts the surface of the lens sample. Under the elastic force of the spring t2, it drives the middle of the seesaw t11 to rotate at the lower end of the rotating rod t12, and at the same time stretches the right side of the elastic plate t13, so that the lower top end of the seesaw t11 maintains elastic extrusion on the surface of the lens sample under the support of the rotating rod t12, thereby ensuring that the eight force-bearing blocks t1 at the outer end press and fix the lens sample evenly in a ring.
[0024] Two circular rods are provided on the side of the limit plate t4, which are distributed in a horizontal state. And a track plate is provided in the horizontal plate 23 and is slidably matched with the circular rod. At the same time, the track plate is installed on the inner side of the upper end of the horizontal plate 23. Thus, by pulling the limit plate t4 to move outward, the diameter width of the limit plate t4 from the central axis position is adjusted according to the size of the lens sample, realizing the effect of adjusting the outer end position of the lens sample.
[0025] Working principle: In the present utility model, the lens sample is placed on the surface of the support structure 24, and the fixing structure 22 is pulled to extrude the upper surface of the lens, so that the lens forms a fixing effect with the middle supported upward and the outer end pressed downward. Thus, the ray emitter at the lower end of the mechanical stage 3 emits rays towards the position of the detection stage 2 below, and then the hydraulic actuator 21 inside the cabinet 1 is controlled to extend and retract, driving the horizontal plate 23 to move horizontally on the upper end of the fixed stage 25 to perform translational detection on the lens sample. When the lens sample is placed on the surface of the support structure 24, the bottom of the sample contacts the vertex of the triangular block w3 in the support structure 24. Under the support of the six triangular blocks w3, the support rod w2 generates vertical elasticity upward through the spring rod w4, and then under the elastic force of the rubber block w1, the upper end of the triangular block w3 extrudes the bottom of the lens sample, maintaining a line contact state at the top of the triangular block w3, preventing easy sliding during contact, avoiding excessive contact area causing dust particles to generate gaps on the contact surface and inclining, and preventing the influence on the horizontal state of the lens sample.
[0026] In the present utility model, according to the diameter size of the lens sample, the circular rod on the side of the limiting plate t4 is manually driven to move outward on the track plate to adjust the width size, and then the transmission plate t3 is pulled. After releasing the transmission plate t3 under the elastic force of the spring t2, it is pressed downward, so that the force-receiving block t1 extrudes the upper surface of the lens sample. Thus, the lower end of the top of the seesaw t11 contacts the surface of the lens sample. Under the elastic force of the spring t2, the middle of the seesaw t11 is driven to rotate at the lower end of the rotating rod t12, and at the same time, the right side of the elastic plate t13 is stretched. So that the seesaw t11, under the support of the rotating rod t12, the lower end of the top maintains an elastic extrusion on the surface of the lens sample, thereby ensuring that the eight force-receiving blocks t1 at the outer end press and fix the lens sample in a circular and uniform manner, and then extrude the upper side of the outer end of the lens sample, forming a mutual support effect with the support of the middle support structure 24 of the lens sample, and further realizing the effect of fixing the lens sample, preventing the lens sample from vibrating when the horizontal plate 23 moves.
