Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage wave plate processing detection, in particular to a detection device for multi-stage wave plate processing. Background Art

[0002] A multi-level wave plate is an optical element used to change the polarization state of light. It is composed of multiple wave plates stacked together, and each wave plate can change the polarization direction of light. Multi-level wave plates are usually used to adjust and control the polarization state of light. For example, in lasers, microscopes, and other optical systems, when processing multi-level wave plates, a detection device is required to detect the multi-level wave plates.

[0003] The existing detection device for multi-level wave plate processing is internally provided with a coaxial light source, a beam limiting plate, and a control board. The control board collects data information of a polarizer, an analyzer, a light intensity detector, and a micro-spectrometer, and is externally connected to a computer so that the information in the control board is transmitted to the computer, thereby calculating the thickness of the quartz glass slide through the light intensity data after various coaxial light sources irradiate the multi-level wave plate to be detected. During detection, a positioning fixture is usually provided inside the operating port of the detection device, and the multi-level wave plate needs to be fixed on the positioning fixture. When detecting multiple multi-level wave plates, it is necessary to wait for the multi-level wave plates to be loaded and unloaded, thereby making the detection efficiency poor. At the same time, when loading the multi-level wave plate, dust in the air is easy to fall onto the surface of the multi-level wave plate. More dust on its surface is easy to affect the detection of the multi-level wave plate, and detection errors are easy to occur. For this reason, we propose a detection device for multi-level wave plate processing. Utility Model Content

[0025] Example

[0026] See also Figure 1-Figure 6 , a detection device for multi-stage wave plate processing shown in the figure includes:

[0027] The side wall of the body 100 is provided with a detection port 110;

[0028] In some embodiments, a coaxial light source, a beam limiting plate, and a control board are disposed inside the main body 100. The control board collects data information of the polarizer, the analyzer, the light intensity detector, and the micro-spectrometer, and is externally connected to a computer so that the information in the control board is transmitted to the computer, thereby calculating the thickness of the quartz glass slide through the light intensity data after various coaxial light sources irradiate the multi-level wave plate to be detected, wherein the structures of the various devices and the coordinated use thereof are prior art.

[0029] The outside of the body 100 is slidably matched with a shielding cover 120, which is made of an opaque plastic plate. A sliding hole 121 is opened on the side wall of the shielding cover 120, and a limiting column 122 fixedly connected to the side wall of the body 100 is arranged inside the sliding hole 121. When the shielding cover 120 slides, the limiting column 122 and the sliding hole 121 are used to limit the shielding cover 120. The front side of the body 100 is slidably matched with a pushing bar 130 connected to the inside of the detection port 110. A plurality of positioning frames 140 are fixedly connected to the top of the pushing bar 130 by bolts. The positioning frame 140 is made of common plastic on the market. A placement cavity 141 is arranged inside the positioning frame 140, and a positioning groove 142 is arranged at the bottom of the placement cavity 141. A plurality of rubber blocks 143 are arranged inside the positioning groove 142. The rubber blocks 143 are hemispherical blocks made of elastic rubber.

[0030] The dust blowing member 200 is matched with the outside of the positioning frame 140, and the rear side of the dust blowing member 200 is fixed to the body 100 by bolts. The side wall of the dust blowing member 200 is rotatably connected with a telescopic rod 210. The telescopic rod 210 uses a device with a model number of SD50 of the brand Botian Shunda on the market. A plurality of rotating ports 201 are opened on the top of the dust blowing member 200, and a rotating member 220 is arranged inside the rotating port 201. An internal pipe 221 is arranged inside the rotating member 220, and an air outlet head 222 is arranged at the output end of the internal pipe 221. The air outlet head 222 is a common air nozzle on the market. A dust filter 230 matched with the internal pipe 221 is arranged on the top of the rotating member 220, and a connecting pipe 231 is arranged at the input end of the dust filter 230. The telescopic rod 210 is electrically connected to a control switch 212;

[0031] In some embodiments, the connecting tube 231 is a high-pressure plastic tube, which is electrically connected to a common external air compressor on the market. The control switch 212 uses a common brand on the market, the Guangdong and Henan model YF-8 timed forward and reverse controller, which realizes the timed extension and retraction of the telescopic rod 210 through advance settings, thereby causing the rotating member 220 to reciprocate.

[0032] Specifically, a plurality of grooves 131 are formed on the top of the push bar 130 . When the shielding cover 120 shields the detection port 110 , the bottom of the shielding cover 120 fits into the grooves 131 .

[0033] Furthermore, a connecting member 211 is disposed on the side wall of the rotating member 220 .

[0034] Furthermore, the telescopic rod 210 is rotatably connected to the bottom of the connecting member 211 .

[0035] Furthermore, the air outlet head 222 is matched with the interior of the dust blowing member 200 .

[0036] It is worth noting that the shielding cover 120 is matched with the outside of the detection port 110 .

[0037] It is worth noting that a filter screen 232 is disposed inside the dust filter element 230 , and the filter screen 232 uses a nylon dust filter screen commonly found on the market.

[0038] In some embodiments, the electrical components and electrical equipment mentioned above all use external power sources.

[0039] In addition, the circuits, electronic components and modules involved in the utility model are all prior art, and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to the internal structure and method.

[0040] Working principle: when multiple multi-stage wave plates are to be inspected, the multi-stage wave plates are placed inside the positioning frame 140 and clamped and positioned with the rubber block 143 of the positioning groove 142, and then the push bar 130 can be pushed backward so that the positioning frame 140 with the multi-stage wave plates placed thereon is moved into the interior of the inspection port 110, and then the shielding cover 120 is slid to the right so that the shielding cover 120 is blocked outside the inspection port 110 with the groove 131 of the push bar 130 under the limit of the limit column 122, and finally the multi-stage wave plates inside the positioning frame 140 are inspected with the device inside the body 100, so that the loading and positioning of the subsequent multi-stage wave plates can be carried out simultaneously when the previous multi-stage wave plate is inspected, which solves the problem that the common inspection device needs to wait for the multi-stage glass slides when conducting inspections. The problem of loading and unloading time is solved, thereby shortening the inspection time of multi-stage wave plate processing and improving the inspection efficiency; before the multi-stage wave plate is inspected, the telescopic rod 210 is retracted and retracted at a fixed time, so that the rotating part 220 reciprocates inside the rotating port 201, and at the same time, the external pressurized air enters the dust filter 230 through the connecting pipe 231, and the dust in the air is filtered by the filter 232, and then the air passes through the connecting pipe 231 and is blown from the air outlet 222 to the multi-stage wave plate of the positioning frame 140. At the same time, the rotating part 220 cooperates with the rotating to perform multi-angle blowing and dust removal on the outer wall of the multi-stage wave plate, which improves the cleanliness of the multi-stage wave plate, avoids the dust on the surface of the multi-stage wave plate from affecting its later inspection, and is conducive to the accurate inspection of the multi-stage wave plate by the detection device.
