Description

Technical Field

[0001] The present invention relates to the technical field of spherical mirror testing, and in particular to a device and method for testing the transmittance of a spherical mirror. Background Art

[0002] Testing the transmittance of spherical mirrors is a key step in evaluating their optical performance and practical value. Transmittance directly impacts the light transmission efficiency of a spherical mirror. High transmittance reduces light loss, ensuring image clarity and color reproduction, and preventing blur or distortion caused by insufficient light transmission. There are various methods for testing the transmittance of spherical mirrors, including dual-path, spectrophotometry, and integrating sphere methods. The integrating sphere method is widely used due to its consistency, high adaptability, and strong interference resistance.

[0003] Currently, when mass-producing and testing spherical mirrors, the lenses are easily scratched and require high precision, requiring meticulous operation during testing, which affects the efficiency of the test work. For example, utility model patent publication number CN210322256U discloses an adjustment device for testing the transmittance of spherical mirrors. The device comprises a base plate, a detection projector fixedly mounted on one side of the upper surface of the base plate, a mounting plate fixedly connected to the upper surface of the base plate, the mounting plate being located to the right of the detection projector, a scale engraved on the upper surface of the base plate, and a distance indicator plate fixedly connected to the upper surface of the base plate, located to the right of the mounting plate. For example, the utility model patent with announcement number CN222070085U discloses an adjustment device that can test the transmittance of a spherical mirror, including a test device and a column. The outer wall of the test device is fixedly connected to the column, and a test projector is installed on the surface of the column. The surface of the test device is fixedly connected to a frame, and the frame is rotatably connected to a stud through a bearing. A knob is fixed to the end of the stud, an adjustment device is provided inside the test device, and a fixing device is provided outside the test device.

[0004] Although the above patent has improved operational efficiency to a certain extent, it is generally only suitable for use in single or small-batch testing environments. Its operation process is highly dependent on manpower and has a low degree of automation. When large-scale spherical mirror testing is required, its efficiency is limited and it cannot adapt to higher testing requirements. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a device and method for testing the transmittance of spherical mirrors, which can effectively solve the problem of low efficiency in the prior art when testing the transmittance of spherical mirrors in large quantities.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A device for testing the transmittance of a spherical mirror comprises an intermittent conveyor belt and a plurality of bearing assemblies mounted on the intermittent conveyor belt. The intermittent conveyor belt is in the shape of an elliptical runway. An optical testing mechanism, a vibration assembly, a pressing assembly, and a release assembly are respectively provided on the sides of the intermittent conveyor belt, each of which cooperates with the bearing assemblies.

[0008] The supporting assembly includes a placing platform and a connecting seat, the middle of each of the placing platform and the connecting seat is provided with a through-hole allowing light to pass through, a plurality of sliding columns are inserted on the top of the placing platform, the sliding columns are tightly attached to the inner wall of the through-hole, a clip is installed on the top of each sliding column, and the bottom ends of the sliding columns are commonly connected to a synchronous frame, a wedge block is vertically slidably installed on the top of the placing platform, and the bottom end of the wedge block is fixedly connected to the synchronous frame, when the supporting assembly passes through the pressing assembly, the wedge block is pressed down, driving the clip to move down and clamp the lens;

[0009] The clip includes a supporting portion, an inclined portion and a limiting portion. When the inclined portion moves downward, it is squeezed by the inner wall of the perforation and becomes vertical.

[0010] In the above-mentioned device for testing the transmittance of a spherical mirror, a card block for locking the height of the wedge block is further provided inside the placement platform. The card block is elastically installed by a spring, and a card slot adapted to the card block is provided on the wedge block.

[0011] In the above-mentioned device for testing the transmittance of a spherical mirror, a mounting opening is provided on the top wall of the placement table, and a convex hook is connected to the top end of the wedge block. When the supporting assembly passes through the releasing assembly, the convex hook is driven to release the wedge block.

[0012] In the above-mentioned device for testing the transmittance of a spherical mirror, the side of the convex hook facing the release component is set as an inclined surface, and the angle between the inclined surface and the horizontal plane is not less than 45°.

[0013] In the above-mentioned device for testing the transmittance of a spherical mirror, a plug ring is provided at the bottom end of the placement table, a slot adapted to the plug ring is provided at the top of the connecting seat, a disc spring connected to the plug ring is installed in the slot, and a paddle is also provided on the outer wall of the plug ring. When the supporting assembly passes through the vibration assembly, the paddle is blocked and drives the placement table to rotate, and then the paddle is released to cause the placement table to vibrate.

[0014] In the above-mentioned device for testing the transmittance of a spherical mirror, the vibration assembly includes a first base and a vibration lever, and the extension length of the vibration lever is adjustable.

[0015] In the above-mentioned device for testing the transmittance of a spherical mirror, a positioning rod is installed on the upper surface of the connecting seat, a positioning hole adapted to the positioning rod is opened on the outer wall of the insert ring, and the end of the positioning rod and the opening of the positioning hole are both rounded.

[0016] In the above-mentioned device for testing the transmittance of a spherical mirror, the pressing assembly includes a second base and a pressing lever, and the releasing assembly includes a third base and a releasing lever. The lower surfaces of the pressing lever and the releasing lever are both flush with the upper surface of the placement table.

[0017] In the above-mentioned device for testing the transmittance of a spherical mirror, the optical testing mechanism includes a C-shaped frame and a light source device. A focusing device connected to the light source device is installed at the top of the C-shaped frame, and an integrating sphere located below the supporting assembly is installed at the bottom of the C-shaped frame.

[0018] The present invention also provides a method for testing the transmittance of a spherical mirror, which is suitable for the device for testing the transmittance of a spherical mirror described above. Multiple carrying assemblies are installed on an intermittent conveyor belt in the shape of an elliptical runway. A lens to be tested is placed at an artificial point on the intermittent conveyor belt. The carrying assembly with the lens to be tested is passed through a vibration assembly, a pressing assembly, an optical testing mechanism and a release assembly in sequence. When the carrying assembly passes through the vibration assembly, it vibrates to flatten the lens to be tested. When passing through the pressing assembly, the lens to be tested is clamped. When passing through the optical testing mechanism, the lens to be tested is tested. When passing through the release assembly, the lens is released. When passing through the artificial point again, the tested lens is removed and a new lens to be tested is placed.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention realizes automatic clamping of the spherical mirror to be measured by cooperating with the bearing assembly and the pressing assembly. An intermittent conveyor belt in the shape of an elliptical runway is provided to mobilize the bearing assembly to operate automatically. When the bearing assembly passes the pressing assembly, the wedge block is pressed down, driving the clamping piece to descend and clamp the edge of the lens. No manual operation is required, and the degree of automation is high.

[0021] 2. After the fixed lens has been tested by the optical testing mechanism, the carrier assembly passes through the release assembly, and the convex hook is driven to move backward to move the clamping block out of the slot. The wedge block is released. Due to the shape characteristics of the inclined part, the clamping piece resets upward to release the lens. At this time, the lens can be easily removed and replaced with a new lens to be tested. It is efficient and convenient. The clamping and releasing processes are completed automatically, and the efficiency is significantly improved.

[0022] 3. After the lens to be tested is placed on the clamp, it may not be completely horizontal and may be skewed. When the supporting assembly passes through the vibration assembly, the paddle is blocked by the vibration lever, causing the placement table to rotate. As the placement table continues to rotate, the paddle eventually breaks through the vibration lever. Under the restoring force of the coil spring, the placement table generates rotational vibration, which drives the lens to be tested on it to vibrate and vibrate it evenly, ensuring that the lens is in a horizontal state to ensure the accuracy of the test results. This is ingenious and convenient, and does not require manual control, further improving test efficiency and test accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example: Refer to Figure 1-11 A device for testing the transmittance of spherical lenses comprises an intermittent conveyor belt and multiple load-bearing assemblies 5 mounted on the intermittent conveyor belt. The intermittent conveyor belt is shaped like an elliptical racetrack. An optical testing mechanism 1, a vibration assembly 2, a pressing assembly 3, and a release assembly 4 are positioned on the sides of the intermittent conveyor belt, each of which cooperates with the load-bearing assemblies 5. The spherical lenses are placed and tested on the intermittent conveyor belt in the shape of an elliptical racetrack, allowing the entire process to be repeated and automated. The conveyor belt is intermittent, and each lens to be tested stops for a period of time (the operator setting the pause time) as it passes the optical testing mechanism 1 for testing. This results in a high degree of automation and reduces reliance on manpower.

[0039] Reference Figure 4-6 , wherein the carrying component 5 includes a placing platform 501 and a connecting seat 502, and the middle of the placing platform 501 and the connecting seat 502 are provided with a through-hole 516 allowing light to pass through. A plurality of sliding columns 515 are inserted on the top of the placing platform 501, and the sliding columns 515 are close to the inner wall of the through-hole 516. A clip 507 is installed on the top of each sliding column 515, and the bottom end of the sliding column 515 is commonly connected to the synchronization frame 514. A wedge block 508 is vertically slidably installed on the top of the placing platform 501, and the bottom end of the wedge block 508 is fixedly connected to the synchronization frame 514. When the carrying component 5 passes through the pressing component 3, the wedge block 508 is pressed down, driving the clip 507 to move down and clamp the lens.

[0040] Specifically, refer to Figure 4-6 The clip 507 includes a supporting portion 5071, an inclined portion 5072 and a limiting portion 5073. When the inclined portion 5072 moves downward, it is squeezed by the inner wall of the through hole 516 and becomes vertical.

[0041] The entire clip 507 is made of an elastic material, such as a metal sheet or plastic sheet. The slide post 515 is in close contact with the inner wall of the perforation 516, and the bottom end of the inclined portion 5072 is also located inside the perforation 516. When the clip 507 moves downward as a whole, the outer wall of the inclined portion 5072 is squeezed by the inner wall of the perforation 516 and gradually deforms into a vertical position. At this time, the multiple clips 507 will jointly clamp the lens to be tested. The limiter 5073 prevents the clip 507 from being completely stuck in the perforation 516, ensuring that the clip 507 always has a tendency to reset upward. When the wedge block 508 is released, the reset force of the inclined portion 5072 causes the wedge block 508 and each clip 507 to move upward, and the clips 507 gradually open, releasing the lens.

[0042] Reference Figure 11 A block 510 for locking the height of the wedge block 508 is further provided inside the placement table 501 . The block 510 is elastically installed by a spring 511 , and a slot 509 adapted to the block 510 is provided on the wedge block 508 .

[0043] When the wedge block 508 is pressed down, the locking groove 509 on the wedge block 508 eventually reaches the position of the locking block 510. At this time, the locking block 510 springs into the locking groove 509 to lock the position of the wedge block 508. Although the shape characteristics of the inclined portion 5072 cause it to have a tendency to return upward, the position of the wedge block 508 is still fixed, thereby maintaining the fixed state of the lens to be tested. When the supporting assembly 5 continues to move forward, it can also stably fix the lens to be tested, ensuring the stability of the lens during testing and ensuring the detection accuracy.

[0044] Reference Figure 8-11 The top wall of the placement platform 501 is provided with an installation opening 512, and the top of the wedge block 508 is connected with a convex hook 513. When the carrying component 5 passes through the release component 4, the convex hook 513 is driven to release the wedge block 508. Figure 1 After passing through the optical testing mechanism 1, the lens test is completed. At this time, the supporting assembly 5 gradually reaches the position of the releasing assembly 4. The convex hook 513 is driven by the releasing assembly 4 to move the clamping block 510 out of the clamping slot 509. The wedge block 508 moves upward due to the restoring force of the clamping piece 507. The clamping piece 507 also moves upward and opens. At this time, the originally clamped lens is released, making it convenient to remove it and replace it with a new lens to be tested.

[0045] It should be noted that the side of the protruding hook 513 facing the release assembly 4 is designed as an inclined surface, and the angle between the inclined surface and the horizontal plane is not less than 45 degrees. The protruding hook 513 having an inclined surface of not less than 45 degrees on the side facing the release assembly 4 ensures that the release assembly 4 has sufficient thrust when contacting the protruding hook 513, which can first drive the protruding hook 513 to move. Only when the resistance generated by the spring 511 is greater will the release assembly 4 press the protruding hook 513 downward, and the release assembly 4 will also be separated from the protruding hook 513 at this time, so as not to hinder the continued operation of the support assembly 5.

[0046] Reference Figure 10 A plug ring 503 is provided at the bottom end of the placement table 501, and a slot adapted to the plug ring 503 is provided at the top of the connecting seat 502. A coil spring 504 connected to the plug ring 503 is installed in the slot, and a paddle 517 is also provided on the outer wall of the plug ring 503. When the carrying component 5 passes through the vibration component 2, the paddle 517 is blocked and drives the placement table 501 to rotate, and then the paddle 517 is released to cause the placement table 501 to vibrate.

[0047] Reference Figure 2 The vibration assembly 2 includes a first base and a vibration lever, and the vibration lever can be adjusted in length. When the lens to be tested is placed on the supporting area composed of multiple clips 507, due to insufficient manual or mechanical operation, the lens to be tested may not be in a horizontal state, and the lens may be skewed. As the supporting assembly 5 continues to move to the position of the vibration assembly 2, the paddle 517 is blocked by the vibration lever, causing the insert ring 503 and the placement table 501 to rotate, until the paddle 517 rotates to finally disengage from the vibration lever. At this time, the placement table 501 is subjected to the restoring force of the coil spring 504, generating a rotational vibration, which evenly vibrates the lens to be tested on the placement table 501, so that the lens to be tested is evenly stressed on the clips 507, ensuring that it is in a horizontal state and stably clamped in the subsequent clamping process, while also ensuring the accuracy of the test results.

[0048] The vibration lever is set to an adjustable length. The longer the vibration lever is extended, the greater the obstruction to the paddle 517. The greater the angle of rotation of the placement table 501, the greater the amplitude generated. In order to prevent the placement table 501 from vibrating too much and shaking off the lens on it, the extension distance of the vibration lever needs to be adjusted to an appropriate size.

[0049] Reference Figure 5A positioning rod 505 is installed on the upper surface of the connecting seat 502, and a positioning hole 506 that matches the positioning rod 505 is opened on the outer wall of the insert ring 503. The end of the positioning rod 505 and the opening of the positioning hole 506 are both rounded. After the supporting component 5 leaves the vibration component 2, the placement platform 501 is in a state of rotational vibration for a certain period of time. In order to restore the stability of the placement platform 501 as soon as possible, the positioning rod 505 is provided to appropriately intervene in the insert ring 503. The end of the positioning rod 505 and the opening of the positioning hole 506 are both rounded. This will not excessively hinder the continued vibration of the placement platform 501, but can also stop the vibration of the placement platform 501 as soon as possible when it is relatively mild, ensuring stability during the subsequent compaction and testing processes.

[0050] Reference Figure 1-2 The pressing assembly 3 includes a second base and a pressing lever, while the releasing assembly 4 includes a third base and a releasing lever. The lower surfaces of both the pressing lever and the releasing lever are flush with the upper surface of the placement platform 501. When the wedge block 508 reaches the position of the pressing assembly 3, the pressing lever gradually presses the wedge block 508 downward via its wedge-shaped surface. The extending length of the pressing lever does not exceed that of the wedge block 508 to avoid interference with other components. The releasing lever cooperates with the protruding hook 513 to release the wedge block 508 from the clamping block 510, releasing the lens clamp. When the protruding hook 513 can no longer be moved, the protruding hook 513 is pressed downward, disengaging the protruding hook 513 from the releasing lever.

[0051] Reference Figure 3 The optical testing mechanism 1 includes a C-shaped frame 101 and a light source device 104. A focusing device 102 connected to the light source device 104 is installed on the top of the C-shaped frame 101, and an integrating sphere 103 located below the supporting component 5 is installed at the bottom of the C-shaped frame 101.

[0052] When the supporting assembly 5 passes through the optical testing mechanism 1, it stops intermittently, and the spherical lens clamped thereon is tested. The supporting assembly 5 passes between the integrating sphere 103 and the focusing device 102. The light source of the light source device 104 can be a laser diode or a light-emitting diode. The focusing device 102 converts the light emitted by the light source device 104 into a parallel beam and focuses it on the lens to be tested. The integrating sphere 103 is a hollow structure with a spherical inner surface and a reflective coating on the inner wall. The top of the integrating sphere is provided with a light inlet and the side is provided with a light outlet. The light outlet is connected to a detector to analyze and calculate the received light. This testing method is relatively common at this stage. For details, please refer to the invention patent with announcement number CN101221088B, which will not be described in detail in this invention.

[0053] The present invention also provides a method for testing the transmittance of a spherical mirror, suitable for use with the aforementioned device for testing the transmittance of a spherical mirror. Multiple supporting assemblies 5 are mounted on an intermittent conveyor belt in the shape of an elliptical runway. A lens to be tested is placed at a manually positioned position on the intermittent conveyor belt. The supporting assemblies 5 containing the lens to be tested are sequentially passed through a vibrating assembly 2, a pressing assembly 3, an optical testing mechanism 1, and a releasing assembly 4. The supporting assemblies 5 vibrate as they pass through the vibrating assembly 2, flattening the lens to be tested. The lens to be tested is clamped as it passes through the pressing assembly 3. The lens to be tested is tested as it passes through the optical testing mechanism 1. The lens is released as it passes through the releasing assembly 4. When the supporting assemblies 5 pass through the manually positioned positions again, the tested lens is removed and a new lens to be tested is placed. The specific implementation of the intermittent conveyor belt is currently very common. Its pause time can be manually set according to specific operating conditions, ensuring stable operation while improving efficiency. The distances between the vibrating assembly 2, the pressing assembly 3, the optical testing mechanism 1, and the releasing assembly 4 can be adjusted according to actual operating conditions, but their order cannot be changed. The above method can significantly improve the efficiency of detection work, has a high degree of automation, and is suitable for use in large-scale detection work.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
