Description

Technical Field

[0001] The present invention relates to the technical field of optical measurement, and particularly to a measuring device and method for automatically detecting the positions of glass holes by a microscope. Background Art

[0002] In today's glass manufacturing and processing industries, the accurate measurement of the positions and sizes of glass holes is of crucial importance. Existing measurement technologies have many deficiencies when faced with tiny and numerous glass holes, and there is an urgent need for improvement and breakthrough.

[0003] Traditional methods for measuring glass holes mainly rely on manual inspection. However, manual inspection has obvious limitations. On the one hand, for small holes with a diameter of only about 50 micrometers, it is very difficult for the human eye to accurately locate these micro-holes when observing a 1-meter-sized glass. Especially when there are multiple micro-holes ranging from 500 to 10,000 distributed on the entire piece of glass, the efficiency of manually identifying and measuring each one is extremely low, making it difficult to meet the high requirements for inspection efficiency and accuracy in modern industrial production. On the other hand, manual measurement is easily affected by subjective factors, and the measurement results may have errors and inconsistencies. Moreover, manual measurement cannot be continuously carried out for a long time and is prone to missed inspections or misjudgments due to fatigue.

[0004] With the development of technology, traditional microscope measurement methods have gradually been applied. Although an ordinary microscope can magnify the image of a glass hole for observation, its functions are relatively single. Generally, it cannot automatically locate micro-holes and requires manual continuous adjustment of the microscope position and focal length to find micro-holes, which is cumbersome to operate and requires a high level of technical proficiency for operators. In addition, traditional microscopes lack effective protection mechanisms. When not in use, the lenses are easily contaminated with dust, collided with, or scratched, affecting the measurement accuracy and service life. The measurement process still requires frequent manual intervention and is difficult to achieve efficient automated measurement, and cannot meet the requirements for rapid and batch detection of glass holes on large-scale production lines.

[0005] Therefore, those skilled in the art have proposed a measuring device and method for automatically detecting the positions of glass holes by a microscope to solve the above problems. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a measuring device and method for automatically detecting the positions of glass holes by a microscope, which solves the problems raised in the above background art.

[0012] Preferably, one-way valves are installed inside both the air jet pipe and the air inlet pipe. The conduction directions of the two one-way valves are opposite.

[0013] Preferably, one end of the reset spring is fixedly connected with the outer side of the moving block, and the other end of the reset spring is fixedly connected with the inner wall of the protective shell.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the attached Figure 1 - attached Figure 8 , the embodiment of the present invention provides a measuring device for automatically detecting the position of glass holes of a microscope, including a support frame 1 and a protective shell 3. Two opening and closing plates 808 are slidably connected to the lower surface of the protective shell 3. A rigid traction rope 801 is fixedly connected to the outside of the opening and closing plate 808. A limiting rod 807 is fixedly connected to the upper side inside the protective shell 3. Two moving blocks 806 are slidably connected to the outer surface of the limiting rod 807. Two reset springs 802 are sleeved outside the limiting rod 807. A traction rod 803 is hinged to the bottom of the moving block 806. A moving plate 804 is slidably connected to the inside of the protective shell 3. An optical microscope 805 and a micro-hole scanning and positioning device are detachably connected to the bottom of the moving plate 804 in sequence. A driving motor two 901 is installed on the outside of the protective shell 3. The output end of the driving motor two 901 is fixedly connected to a driving gear 902. Two driving racks 903 are slidably connected to the outer surface of the protective shell 3. A connecting strip 904 is fixedly connected to the outside of the driving rack 903. One end of the reset spring 802 is fixedly connected to the outside of the moving block 806, and the other end of the reset spring 802 is fixedly connected to the inner wall of the protective shell 3. The end of the traction rod 803 away from the moving block 806 is hinged to the outside of the moving plate 804. The outside of both driving racks 903 is meshed and connected to the outside of the driving gear 902. The bottom of the connecting strip 904 is fixedly connected to the outside of the opening and closing plate 808.

[0023] Specifically, when the driving motor two 901 is started, the connected driving gear 902 rotates accordingly. The driving gear 902 drives the two driving racks 903 to move in opposite directions. The connecting strip 904 drives the two opening and closing plates 808 to move along the chute at the bottom of the protective shell 3 under the action of the traction force, so as to open the protective shell 3. By starting the driving motor two 901 again, but this time driving the driving gear 902 to rotate in the reverse direction. This causes the two driving racks 903 to move in the opposite direction to the opening direction, and the opening and closing plates 808 are pulled by the connecting strip 904 to close along the chute at the bottom of the protective shell 3.

[0024] While the opening and closing plate 808 is moving, the rigid traction rope 801 drives the moving block 806 to move along the outer surface of the limiting rod 807. The movement of the moving block 806 causes the top of the traction rod 803 to swing, and the traction force of the traction rod 803 drives the moving plate 804 to move downward along the inner wall of the protective housing 3. The downward movement of the moving plate 804 drives the optical microscope 805 and the micro-hole scanning positioning device to move synchronously until the mirror surface of the optical microscope 805 moves outside the protective housing 3, preparing for glass hole measurement.

[0025] When it is necessary to retract the optical microscope 805 and the micro-hole scanning positioning device, the elastic force of the return spring 802 is used to make the moving block 806 return to the initial position along the limiting rod 807. The traction rod 803 drives the moving plate 804 to move upward, thereby retracting the optical microscope 805 and the micro-hole scanning positioning device into the protective housing 3, completing automatic storage, and preparing for the next measurement.

[0026] A driving motor 204 is fixedly installed on the rear side of the support frame 1. The output end of the driving motor 204 is fixedly connected to a driving screw 206. The outside of the driving screw 206 is threadedly connected to a threaded sleeve 207. The top of the threaded sleeve 207 is fixedly connected to a connecting frame 203. The top of the connecting frame 203 is connected to a support column 201 through an electric turntable 202. An electric guide rail is installed on the outside of the support column 201. An electric slider is installed on the outer surface of the electric guide rail. A fixing frame 205 is installed on the outside of the electric slider. The lower side through hole of the threaded sleeve 207 is slidably connected to a guide rod 4. The left and right ends of the guide rod 4 are fixedly connected to the outside of the support frame 1. The fixing frame 205 is fixedly connected to the outside of the protective housing 3.

[0027] Specifically, the support frame 1 serves as the main support structure of the entire device, providing an installation foundation and support force for other components, and ensuring the overall stability and rigidity of the device.

[0028] The driving screw 206 is fixedly connected to the output end of the driving motor 204. When the driving motor 204 is started, the driving screw 206 will rotate accordingly. It has threads on the outside and cooperates with the threaded sleeve 207. The threaded sleeve 207 can convert the rotational motion of the driving screw 206 into its own linear motion. The electric turntable 202 can drive the support column 201 to rotate, thereby realizing the rotation of the optical microscope 805 in the horizontal direction. The electric guide rail is a guiding and driving device. An electric slider is installed on its outer surface, which can drive the optical microscope 805 to move along the Z-axis direction.

[0029] When the optical microscope 805 needs to be moved along the X-axis direction, the drive motor 1 204 is started, and the output end of the drive motor 1 204 drives the drive screw 206 to rotate. Since the drive screw 206 cooperates with the threaded sleeve 207, the threaded sleeve 207 moves linearly along its outer surface under the rotation of the drive screw 206. The threaded sleeve 207 drives the support column 201 to move synchronously through the connecting frame 203, thereby realizing the movement of the optical microscope 805 along the X-axis direction.

[0030] Movement in the Z-axis direction: To achieve the movement of the optical microscope 805 in the Z-axis direction, the electric guide rail and the electric slider are used. Under the guidance of the electric guide rail, the electric slider drives the fixed frame 205 and the protective shell 3 connected thereto and the optical microscope 805 to move upward or downward. In this way, the distance between the optical microscope 805 and the glass can be adjusted to ensure that it can accurately align with the position of the glass hole.

[0031] Horizontal rotation: The optical microscope 805 rotates horizontally by driving the support column 201 to rotate through the electric turntable 202. By precisely controlling the rotation angle of the electric turntable 202, the orientation of the optical microscope 805 can be changed, so that the glass hole can be measured from different angles.

[0032] Through the coordinated work of the above structures, the measuring device can realize the flexible movement and rotation of the optical microscope 805 in three-dimensional space, meet the needs of all-round detection and measurement of glass holes, and improve the accuracy and efficiency of measurement.

[0033] A vacuum pump 501 is installed on the front side of the support frame 1, and a vacuum tube 502 is fixedly connected to the output end of the vacuum pump 501. A supporting platform 504 is fixedly connected to the top of the support frame 1. A plurality of negative pressure holes 503 are opened on the upper surface of the supporting platform 504, and the vacuum tube 502 is connected to the plurality of negative pressure holes 503.

[0034] Specifically, when it is necessary to measure the glass, the glass to be tested is first placed steadily on the upper surface of the carrier 504. Then the vacuum pump 501 is started, and the vacuum pump 501 starts to work, generating suction through the vacuum tube 502 connected to its output end. The vacuum tube 502 is connected to a plurality of negative pressure holes 503 on the carrier 504, so that the negative pressure holes 503 generate negative pressure. Under the action of atmospheric pressure, the glass is adsorbed on the carrier 504, thereby ensuring that the glass remains stable during the measurement process without displacement or shaking, providing reliable positioning and support for subsequent measurement operations.

[0035] Two fixing cylinders 702 are fixedly connected to the inner side wall of the protective shell 3. A rubber piston 704 is slidably connected inside the fixing cylinder 702. A movable frame 705 is fixedly connected to the outer side of the rubber piston 704. An air inlet pipe 703 and an air jet pipe 701 are sequentially communicated with the outer side of the fixing cylinder 702. One-way valves are installed inside both the air jet pipe 701 and the air inlet pipe 703, and the conduction directions of the two one-way valves are opposite. One end of the air jet pipe 701 penetrates through the outer side of the protective shell 3 and is arranged at the bottom of the protective shell 3.

[0036] Specifically, the rubber piston 704 is used to change the air volume inside the fixing cylinder 702, thereby generating an air flow. The air inlet pipe 703 is used to introduce external air into the inside of the fixing cylinder 702. The air jet pipe 701 is used to discharge the air inside the fixing cylinder 702 and spray it onto the mirror surface of the optical microscope 805 and the mirror surface of the microhole scanning and positioning device. The design of the one-way valve ensures that air can only enter the fixing cylinder 702 from the air inlet pipe 703 and be discharged from the air jet pipe 701. When the moving block 806 moves along the outer surface of the limiting rod 807, it will drive the rubber piston 704 at one end of the movable frame 705 to move along the inner wall of the fixing cylinder 702. At this time, the one-way valve inside the air inlet pipe 703 is in a closed state to prevent air from flowing back from the air inlet pipe 703; while the one-way valve inside the air jet pipe 701 is in an open state, so that the air inside the fixing cylinder 702 is compressed and discharged through the air jet pipe 701. The ejected air forms an air flow, which directly blows onto the mirror surface of the optical microscope 805 and the mirror surface of the microhole scanning and positioning device, blowing away the dust particles attached to the mirror surface, thereby achieving the effect of cleaning dust. This can ensure the cleanliness of the mirror surface and improve the accuracy of measurement.

[0037] One side of the top of the support frame 1 is fixedly connected with a display 6, and the display 6 is used to display the measurement data of the optical microscope 805.

[0038] Specifically, during the measurement process, the optical microscope 805 will transmit the collected glass hole images and measured dimension data such as diameter and depth to the display 6. The display 6 displays these data in intuitive forms such as graphics and numbers, enabling the operator to clearly and accurately understand the measurement results. The display 6 can also display information such as the operating status and operating parameters of the measuring device, helping the operator to monitor the measurement process in real time and ensure the smooth progress of the measurement. For example, display information such as the current position, moving speed, and measurement progress of the optical microscope 805.

[0039] A usage method of a measuring device for automatically detecting the position of glass holes of a microscope includes the following operating steps; I. Startup and preparation: Place the glass to be detected steadily on the upper surface of the carrier 504, and start the vacuum pump 501 to generate suction in the vacuum tube 502. The vacuum tube 502 is connected to the negative pressure hole 503, further generating negative pressure in the negative pressure hole 503 to fix the glass on the carrier 504, ensuring that the glass remains stable during measurement.

[0040] Start the second drive motor 901 to drive the drive gear 902 to rotate. The drive gear 902 drives the two drive racks 903 to move in opposite directions. Under the action of the traction force, the connecting bar 904 drives the two opening and closing plates 808 to move along the chute at the bottom of the protective shell 3 to open the protective shell 3.

[0041] While the opening and closing plate 808 is moving, the rigid traction rope 801 drives the moving block 806 to move along the outer surface of the limiting rod 807. When the moving block 806 moves, the top of the traction rod 803 swings, and under the traction force of the traction rod 803, the moving plate 804 moves downward along the inner wall of the protective shell 3.

[0042] The moving plate 804 moves downward, driving the optical microscope 805 and the micro-hole scanning and positioning device to move synchronously until the mirror surface of the optical microscope 805 is moved outside the protective shell 3, preparing to measure the glass hole.

[0043] II. Dust removal operation: As the moving block 806 moves along the outer surface of the limiting rod 807, it drives the rubber piston 704 at one end of the movable frame 705 to move along the inner wall of the fixed cylinder 702. At this time, the one-way valve in the air jet pipe 701 is in the open state, while the one-way valve in the air inlet pipe 703 is in the closed state. The air in the fixed cylinder 702 is discharged through the air jet pipe 701, thereby cleaning the dust on the mirror surface of the optical microscope 805 and the mirror surface of the micro-hole scanning and positioning device, ensuring the accuracy of the measurement.

[0044] III. Measurement operation: Movement in the X-axis direction: Start the first drive motor 204 to drive the drive screw 206 to rotate. The drive screw 206 cooperates with the threaded sleeve 207, and the threaded sleeve 207 moves along the outer surface of the drive screw 206, driving the connecting frame 203 and the support column 201 to move synchronously, thereby driving the optical microscope 805 to move along the X-axis direction.

[0045] Movement in the Z-axis direction: Through the cooperation of the electric guide rail and the electric slider, the movement of the optical microscope 805 in the Z-axis direction is realized. The electric slider moves along the electric guide rail, driving the optical microscope 805 to move up or down to adjust the distance between the optical microscope 805 and the glass, ensuring that the optical microscope 805 can accurately align with the position of the glass hole.

[0046] Horizontal rotation: The support column 201 is driven by the electric turntable 202 to rotate, and the optical microscope 805 rotates horizontally accordingly. By controlling the rotation angle of the electric turntable 202, the orientation of the optical microscope 805 can be adjusted to measure the glass holes from different angles.

[0047] Through the coordinated action of the first driving motor 204, the electric guide rail, the electric slider and the electric turntable 202, the optical microscope 805 can move flexibly in three-dimensional space and quickly and accurately locate all the micro-hole positions on the glass. After the micro-hole scanning and positioning device aligns with the micro-hole, it transmits the position information to the optical microscope 805. The optical microscope 805 aligns with the micro-hole and magnifies the image. The imaging sensor converts the optical image into a digital signal. The image processing system processes and analyzes the digital signal, calculates the size parameters such as the diameter and depth of the micro-hole, records the measurement data, and displays the measurement results in real time through the display 6, providing intuitive data support for technicians.

[0048] IV. End and reset: After the measurement is completed, turn off the first driving motor 204, the second driving motor 901 and other related driving devices to stop the movement of the optical microscope 805. Start the second driving motor 901 again, drive the driving gear 902 to rotate in the reverse direction, so that the two driving racks 903 move in opposite directions. The opening and closing plate 808 closes along the chute at the bottom of the protective shell 3 under the traction of the connecting bar 904. Under the elastic force of the reset spring 802, the moving block 806 returns to the initial position along the outer surface of the limiting rod 807. The traction rod 803 drives the moving plate 804 to move upward, and the optical microscope 805 and the micro-hole scanning and positioning device are retracted into the protective shell 3 to complete automatic storage and prepare for the next measurement.
