Description

Technical Field

[0001] The present invention relates to the field of optical equipment and detection and analysis technology, and in particular to a miniaturized portable white light mirror zeroing instrument and a method for using the same. Background Art

[0002] Among various optical sighting systems, white light products have become increasingly popular in recent years. These products typically require zero-point testing and calibration before shipment to ensure performance. Currently, common zero-point sights on the market are bulky and heavy, so they are typically installed in laboratories, failing to meet the technical requirements for on-site testing and debugging in specialized situations.

[0003] Our company previously developed a simple zero-position measurement device for infrared thermal imagers (Chinese Patent CN112857581B). This zero-position measurement device boasts a simple structure, easy operation, good repeatability, and high accuracy, effectively reducing inspection costs and errors caused by human intervention. Building on this foundation, and to address the portability issues of existing zero-position meters, we have developed a new, miniaturized, portable white-light microscope zero-position meter. Summary of the Invention

[0004] The main purpose of the present invention is to solve the above-mentioned problems existing in the prior art and provide a miniaturized portable white light microscope zeroing instrument, which mainly includes a parallel light tube assembly 1, an observation group 2, a main frame 7, a light source, and a fixing assembly for the white light microscope to be tested, wherein the light source, the parallel light tube assembly 1, the fixing assembly for the white light microscope to be tested, and the observation group 2 are fixed on the main frame 7 in sequence along a straight line from left to right or from right to left, and the light emitted by the light source passes through the parallel light tube assembly 1 and the white light microscope to be tested, and then forms an image on the observation group 2 and is observed.

[0005] Furthermore, the collimator assembly 1 is specifically a specially made miniaturized collimator, which has the advantages of light weight and small size, thereby improving the portability of the instrument.

[0006] Furthermore, the zero position meter also includes an annular support seat 12 , and both ends of the parallel light tube assembly 1 are respectively fixed in the annular support seat 12 , and the annular support seat 12 is directly or indirectly fixed on the main frame 7 .

[0007] Furthermore, the annular support 12 includes a fixing ring and an adjusting screw, and at least three threaded holes are symmetrically arranged on the circumference of the fixing ring, and the adjusting screws are fixed in the threaded holes. By adjusting the feed rate of the adjusting screws, the optical axis can be fine-tuned conveniently and quickly.

[0008] Furthermore, the observation group 2 includes a clamp 6 and a visual device, the visual device is fixed in the clamp 6, and the clamp 6 is directly or indirectly fixed to the main frame 7.

[0009] Furthermore, the visual device is specifically a diopter, a magnification meter, etc.

[0010] Furthermore, the parallel light tube assembly 1 and the observation group 2 both have a height adjustment structure, and the optical axis centers of the two can be made to coincide (ie, coaxial and concentric) by adjusting the height adjustment structure.

[0011] Furthermore, the height adjustment structure is specifically a pad, and the corresponding height adjustment method is to increase or decrease the number of pads or change the thickness of the pads, so that the optical axis center of the parallel light tube assembly 1 and the observation group 2 coincides with the optical axis center of the white light mirror to be measured.

[0012] Furthermore, the zeroing instrument also includes a support rod 8. A guide rail is provided on the side of the main frame 7 parallel to the optical axis, and screws pass through the support rod 8 and fix it in the guide rail. The support rod 8 slides along the guide rail to the appropriate position and then tightens the screws, which can conveniently adjust the angle of the optical axis.

[0013] Furthermore, the zeroing instrument includes a support plate 9. The observation group 2 is fixed to the support plate 9, which is connected to the main frame 7 by a slide rail. During use, the slide rail can be extended and retracted to conveniently and quickly adjust the distance between the white light microscope to be tested and the visual device, facilitating better observation and adjustment of the zero position of the white light microscope to be tested.

[0014] Furthermore, the light source is specifically an LED bulb, and is powered by a battery or a mobile power supply.

[0015] Furthermore, the zero position meter also includes a tailstock 14 , and the light source is fixedly connected to the main frame 7 via the tailstock 14 .

[0016] Furthermore, the white light mirror fixing assembly to be tested includes a fixing seat 10 and a mounting seat 11 , wherein the white light mirror to be tested is fixed on the mounting seat 11 , and the thus formed assembly is fixed on the main frame 7 via the fixing seat 10 .

[0017] The second object of the present invention is to provide a method for using the above-mentioned miniaturized portable white light microscope zero position meter, comprising the following steps: (a) sliding the support rod 8 back and forth to adjust the angle of the optical axis, and locking the support rod 8 after the requirement is met; (b) fixing the white light microscope to be tested to the white light microscope fixing assembly to be tested, fixing the visual device to the observation group 2, and adjusting the height of the light source, parallel light tube assembly 1, the white light microscope to be tested and the visual device so that the centers of their optical axes are coaxial and concentric; (c) turning on the light source to perform zero position detection on the white light microscope to be tested.

[0018] Furthermore, after the test is completed, the white light mirror to be tested and the visual equipment are removed and packed, the locking state of the support rod 8 is released, and it is rotated to be flat and then locked.

[0019] The white-light scope zeroing instrument provided by the present invention effectively solves the long-standing problem of inconvenient testing and debugging of white-light sights in certain special circumstances or situations. The zeroing instrument boasts advantages such as small size, light weight, portability, and simple operation. It can be easily transferred from one indoor or outdoor location to another, and can be assembled and tested in a short period of time, adapting to the rapid inspection and calibration of optical sights in various locations. Due to its compact modular design, the entire zeroing instrument has a relatively rational structure, is easy to disassemble and install, and has low production and use costs.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to fully understand the technical solutions and beneficial effects of the present invention, further description will be given below in conjunction with specific embodiments and drawings.

[0025] To address the problem of poor portability of existing white light microscope zeroing instruments due to their large size and heavy weight, we have modularized the design of each part to make the white light microscope zeroing instrument smaller, lighter, and more convenient to carry while ensuring detection accuracy, ensuring that scientific research and testing personnel can still perform corresponding operations in different scenarios and environments.

[0026] The miniaturized portable white light mirror zeroing instrument provided by the present invention is as follows Figure 1-3As shown, it mainly includes a collimator assembly 1, an observation group 2, a main frame group 3, a micro light source group 4, etc. The collimator assembly 1 adopts a special miniaturized collimator with light weight and small size. The observation group 2 is composed of a first cushion block 5, a clamp 6 and visual equipment (such as a diopter and a magnification meter, etc.). The main frame group 3 includes a main frame 7, a strut 8, a support plate 9, a fixing seat 10, a mounting seat 11, an annular support seat 12, a second cushion block 13, and a tailstock 14. The micro light source group 4 includes an LED bulb, a USB harness, and a power supply (such as a battery or a mobile power supply). The white light microscope zero position meter uses the main frame 7 (a whole metal plate with a hollowed-out middle part to reduce weight) as the installation body, and the micro light source group 4, the collimator assembly 1, the white light microscope to be tested, the observation group 2 and other components are directly or indirectly fixed on the main frame 7 from left to right. During this process, the center of the white light mirror to be tested is used as a reference to adjust the center of the LED bulb of the micro light source group 4, the center of the parallel light tube, and the center of the visual device on the observation group 2 to ensure that they are all coaxial and concentric. In this way, the light emitted by the bulb passes through the parallel light tube, the white light mirror to be tested, and the visual device on the observation group 2 in turn, and finally forms an image on the visual device for the operator to observe and record.

[0027] like Figure 1 As shown, the micro light source assembly 4, the collimator assembly 1, the white light mirror to be measured, and the observation group 2 are arranged in a straight line from left to right along the optical axis. The micro light source assembly 4 is fixedly connected to the upper end of the tailstock 14 by screws, and the lower end of the tailstock 14 is fixedly connected to the left end face of the main frame 7 by multiple screws.

[0028] like Figure 1 、 3 As shown, a collimator assembly 1 is positioned to the right of the micro-light source assembly 4, its ends respectively mounted on two annular support blocks 12. Several second spacers 13 are placed at the bottom of the annular support blocks 12, which are then fixed to the main frame 7 via screws. By selecting spacers of varying thicknesses or increasing or decreasing the number of spacers, the height of the collimator can be easily and quickly adjusted. By tightening or loosening three symmetrically arranged screws on the annular support blocks 12, the collimator's optical axis can be easily and quickly fine-tuned.

[0029] like Figure 1 、 3 As shown, a white light microscope to be tested (not shown) is provided on the right side of the collimator assembly 1 and is fixed to a mounting base 11, which is fixed to the main frame 7 via a fixing base 10. Considering that different white light microscope products to be tested may have different clamping methods, different types of mounting bases 11 are designed and are switched and fixed via the fixing base 10.

[0030] like Figure 1-2As shown, an observation group 2 is positioned to the right of the white-light microscope to be tested. The visual device of observation group 2 is secured in a clamp 6. A first spacer 5 is placed at the bottom of the clamp 6. The clamp 6 and the first spacer 5 are screwed to the right end of a support plate 9. The support plate 9 is slidably connected to the main frame 7 via a guide rail. After adjusting the distance between the visual device and the white-light microscope to be tested, the support plate 9 is screwed to the main frame 7. Similarly, by selecting spacers of different thicknesses or increasing or decreasing the number of spacers, the height of the visual device can be easily and quickly adjusted.

[0031] As a supporting feature, guide rails are symmetrically arranged on the sides of the main frame 7 along the optical axis (i.e., the length direction). Screws are inserted through the through holes at the top of the support rods 8 and fixed to the guide rails of the main frame 7. By changing the fixing position of the support rods 8, the pitch angle of the optical axis can be easily and quickly adjusted to better complete the test.

[0032] The method of using the miniaturized portable white light mirror zeroing instrument is as follows:

[0033] Installation and Testing: First, use a wrench or screwdriver to loosen the screws on the support rod 8. Adjust the position of the support rod 8 according to the tester's usage habits so that the pitch angle of the entire device meets the requirements, then retighten the screws. Depending on the size of the site, power supply, and ease of operation, place the zeroing instrument securely. Unscrew the power cord fixed to the rear end of the micro-light source assembly 4 and connect the power supply. Mount the white light microscope to be tested on the mounting base 11. Place the visual device, such as a diopter or magnification meter, in the clamp 6 and secure it. Using the center height of the visual device as a reference, adjust the center height of the micro-light source assembly 4 and the collimator assembly 1 by adding or removing spacers or changing the thickness of the spacers so that the optical axes of the light source, collimator, white light microscope to be tested, and the visual device are coaxial and concentric. Use the guide rails to adjust the distance between the white light microscope to be tested and the visual device on the observation group 2 for better observation. After adjustment, turn on the power switch of the micro-light source assembly 4 to emit light. The tester can observe and record the visual device through the visual device.

[0034] Disassembly and Packing: Turn off the power supply to the miniature light source assembly 4. Use a wrench or screwdriver to loosen the clamp 6 and mounting bracket 11. Remove the visual inspection device and the product to be inspected. Use a wrench or screwdriver to loosen the screws on both sides of the support rod 8, lay it flat, and then re-tighten it. Restore the power supply and visual inspection device.

[0035] The miniaturized portable white light microscope zeroing instrument provided by the present invention has been optimized and improved in structure. Under the premise of ensuring detection accuracy and normal use, the device volume has been reduced and the weight of the device has been reduced, making it more convenient to carry, and ensuring that scientific research and testing personnel can complete the detection of white light microscopes and other products in different places.
