Description

Technical Field

[0001] This invention relates to the field of prism inspection, and in particular to a multidimensional optical axis detector for prism inspection and its usage method. Background Technology

[0002] Currently, traditional optical axis lens reflection testing typically uses a single reflection probe. During the testing process, the prism is fixed, and the reflection probe illuminates the prism. The mirror test data is then obtained through a miniature fiber optic spectrometer. This device presents two challenges: First, because the reflection probe is fixed, the prism needs to be fixed at different angles when testing different faces, which can damage the lens due to the fixture. Second, when testing multiple mirrors simultaneously, additional tools are required, making it impossible to test the reflection of one mirror while another is being illuminated, resulting in low efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] like Figure 1-8 As shown, a multidimensional optical axis detector for prism detection includes a circular track 1 and a reflective probe 2.

[0033] A circular track 1 is used to fix the reflective probe; a fixing sleeve 3 is provided at the bottom of the circular track 1, and a rotating shaft 4 is provided inside the fixing sleeve 3. The bottom of the rotating shaft 4 is connected to the base; a clamping device 5 is provided at the top of the rotating shaft 4; a receiving cavity 101 is provided inside the circular track 1, and an entrance 102 communicating with the receiving cavity 101 is provided on the outer side of the top of the circular track 1; a circular slide 103 is provided on the inner diameter surface of the circular track 1.

[0034] The reflective probe 2 is used to emit and detect light sources. The bottom of the reflective probe 2 is connected to the arc-shaped base 6, which is embedded in the circular track 1. The arc-shaped base 6 consists of an upper base 601 and a lower base 602. Multiple sets of springs 7 are provided between the upper base 601 and the lower base 602. All springs are made of alloy spring steel. A fixing hole 6011 is provided at the center of the upper base 601. A fixing post 8 is provided between the reflective probe 2 and the arc-shaped base. The fixing post 8 is connected to the fixing hole by threads. A rotating seat is provided between the fixing post and the fixing body of the reflective probe. The rotating seat is used to adjust the illumination angle of the reflective probe.

[0035] like Figure 3 As shown, the height of the upper base 601 and the lower base 602 when the spring stroke is compressed to its shortest value is lower than the height of the receiving cavity 101. After entering the receiving cavity, the spring returns, and the elastic force pushes the upper base and the lower base to both sides, with the upper base abutting against the receiving cavity. The upper base 601 has a base rubber pad 9 on the side away from the spring, and the receiving cavity 101 has a rubber pad 10 on the side directly opposite to the base rubber pad 9. The contact between the two sets of rubber pads increases the friction, preventing relative displacement and improving stability.

[0036] like Figure 4 , 6 As shown in Figures 7 and 8, the top of the rotating shaft 4 is provided with a retractable cylindrical platform 11, and the center of the rotating shaft 4 is provided with a circular cavity 401. A compression spring 12 is provided inside the cylindrical platform 11. The circular cavity 401 is provided with a vertical first slide rail 4011, a second slide rail 4012, and a transverse slide rail 4013 connecting the bottom of the first slide rail and the bottom of the second slide rail. A limiting post 1101 is provided on the side of the cylindrical platform 11. The limiting post 1101 slides and engages with the first slide rail, the second slide rail, and the transverse slide rail. The spring provides an upward elastic force to lift the cylindrical platform. When the limiting post is in the first slide rail, the top plane of the cylindrical platform is flush with the plane of the rotating shaft. After pressing the cylindrical platform down to the bottom, it is rotated to move the limiting post from the transverse slide rail to the second slide rail. After releasing the cylindrical platform, the cylindrical platform rises, and the limiting post is located at the top of the second slide rail, realizing the raising of the cylindrical platform, which facilitates the illumination of the smaller prism from the lower left or lower right without being blocked by the rotating shaft body.

[0037] like Figure 4 As shown, the clamping device 5 includes a horizontal plate 501, a clamping plate 502, and a spiral screw 503. One end of the spiral screw 503 is connected to the inner wall of the horizontal plate 501 via a bearing, and the other end protrudes from the outer side of the horizontal plate 501 and is provided with a handle. The spiral screw 503 located inside the horizontal plate 501 is provided with symmetrical left-hand and right-hand threads. A sliding groove 5011 is provided on the upper side of the horizontal plate 501. A sleeve 13 is provided on the spiral screw 503. A bracket 1301 is provided on the sleeve 13. The bracket is located inside the sliding groove 5011 and is connected to the clamping plate after protruding from the sliding groove. A rubber layer is provided on the inner side and top of the clamping plate 502. Since the sleeve is limited by the bracket and the sliding groove, the rotation of the sleeve can be controlled by rotating the screw through the handle, thereby realizing the left and right lateral movement of the clamping plate. The rubber layer further protects the prism structure and avoids damage to the prism.

[0038] like Figure 4-5 As shown, the horizontal plate 501 is placed on the cylindrical platform 11 in the diametrical direction and is integrally connected; the top of the rotating shaft 4 has a groove 402 in the diametrical direction, and the horizontal plate 501 is embedded in the groove 402. That is, when the cylindrical platform is in the first slide, the main body of the horizontal plate is located in the groove and will not protrude from the rotating shaft, ensuring the stability during prism installation and preventing the prism from becoming unstable due to the protrusion of the bottom horizontal plate.

[0039] like Figure 1 As shown, the rotating shaft 4 and the fixed sleeve 3 are provided with two bearings 14, one above the other, and a support washer 15 is provided between the two bearings 14. The overall rotation of the circular track is achieved through the bearings and the support washer.

[0040] like Figure 1 , 4 As shown, when the spring is compressed to its minimum stroke, the other end of the fixed column 8 protrudes outside the circular slide 103, ensuring that the reflective probe does not come into contact with the circular track, thereby squeezing the upper base and moving the entire base.

[0041] like Figure 1 As shown, the reflection probe 2 is electrically connected to the miniature fiber optic spectrometer and the light source; the light source uses an HLS-1 halogen tungsten lamp or an FCLS-LED fiber-coupled LED light source; the fiber optic reflection probe is used in conjunction with the spectrometer and the light source to build a miniature optical sensing system to test the reflection and fluorescence of solid surfaces, as well as the backscattering and fluorescence of liquid and powder samples. The reflection probe can be optimized for the ultraviolet-visible (185–1100 nm) or visible-near-infrared (400–2100 nm) wavelength range, or a combination of these two wavelength ranges.

[0043] Depending on the size of the prism to be tested, place it on the rotating shaft or on the cylindrical platform after raising it; fix the prism with the clamping device, or place it on the clamping device; rotate the circular track to align it with the surface of the prism to be tested; rotate the reflection probe to align it with the surface of the prism to be tested; start the light source and the miniature fiber optic spectrometer to record the data.

[0044] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the inventive concept should fall within the protection scope of the present invention.
