Description

Technical Field

[0001] This utility model belongs to the field of glass panel testing devices, specifically, it relates to a glass panel transmittance testing device. Background Technology

[0002] Glass panels are widely used in modern industrial production and daily life, from building curtain walls and car windshields to displays for electronic devices such as mobile phones and tablets. Their performance directly affects product quality and user experience. As a key indicator for measuring the optical performance of glass panels, light transmittance not only determines the light-gathering and display effects of glass, but is also closely related to energy-saving and environmental protection characteristics. Currently, it is not convenient to test the light transmittance of photovoltaic glass by passing light through fiber optic glass at different angles during testing.

[0003] Chinese patent publication number CN221550490U discloses a testing device for the light transmittance of photovoltaic glass. This device allows a tester to adjust the test head, causing a slider fixedly connected to the outer surface of the test head to move within a sliding groove. This adjusts the angle between the light emitted from the light outlet on the outer surface of the test head and the detection port, simulating the trajectory of normal sunlight. The device then tests the light transmittance of fiber optic glass placed on the testing platform and at the detection port, thus enabling light to pass through the fiber optic glass at different angles for transmittance testing, ensuring high transmittance. However, when monitoring multiple glass panels, the device requires placing each panel sequentially at the detection port, and the test head must be stopped when moving the glass panels, reducing overall testing efficiency.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] Please see Figure 1-9As shown, this embodiment provides a glass panel transmittance detection device, including a detection platform 1, with a first rotating shaft 2 rotatably connected to its top. The detection platform 1 is provided with a grooved wheel intermittent drive mechanism 6 that drives the first rotating shaft 2 to rotate. Multiple connecting plates 3 are fixedly installed on the first rotating shaft 2 along its circumference. Each of the multiple connecting plates 3 is fixedly connected with a placement plate 4 with a through hole 10 in the center. A clamping plate 13 is slidably connected to the placement plate 4 relative to the through hole 10. The placement plate 4 is provided with a drive assembly 8 that drives the clamping plate 13 to move relative to it. A light source emitting mechanism 23 is fixedly installed on the detection platform 1 relative to the through hole 10. A photodetector 24 is fixedly installed on the placement platform relative to the light source emitting mechanism 23.

[0044] Specifically, in this embodiment, the intermittent drive mechanism 6 of the Geneva wheel includes a motor, a Geneva wheel, and a dial. Its structure, installation position, and working principle are all existing technologies and will not be described here. In the initial state, the intermittent drive mechanism 6 stops the first rotating shaft 2 at the initial position, with one of the placement plates 4 aligned with the loading position. An operator or robotic arm places the glass panel to be inspected on the placement plate 4, aligning its detection position with the central through-hole 10. Then, the drive assembly 8 drives two clamping plates 13 to move synchronously towards the through-hole 10, clamping the glass panel. After loading, the intermittent drive mechanism 6 starts working. The cylindrical pin of the driving wheel is embedded in the radial groove of the driven Geneva wheel, driving the first rotating shaft 2 to rotate. The first rotating shaft 2 drives the connecting plate 3 and the placement plate 4 to rotate, each rotation at a fixed angle. After rotation stops, the placement plate 4 carrying the glass is accurately aligned with the detection position where the light source emitting mechanism 23 and the photodetector 24 are located. The central through-hole 10 of the placement plate 4 is precisely aligned with the light source emitting mechanism 23 and the photodetector 24. The light source emitting mechanism 23 (such as an LED light source or a laser emitter) emits a beam of light of a specific wavelength, which passes through the through-hole 10 area of ​​the glass panel. The light passing through the glass is received by the photodetector 24 and converted into an electrical signal. The photodetector 24 transmits the signal to the data processing system, and the detection data is stored in the system. It can be displayed synchronously on the operation interface or transmitted to the production management system. The grooved wheel mechanism starts again, turning the detected glass panel away from the detection station, and at the same time turning the next glass panel to be inspected to the detection position. Repeating the above steps can realize the rapid detection of multiple glass panels. The glass panel is rotated back to the unloading station with the placement plate 4. The drive component 8 runs in reverse, the clamping plate 13 releases the glass, and the operator or robotic arm takes away the detected glass, places a new sample to be inspected, and enters the next cycle. The overall structure and operation steps are simple, realize multi-station cyclic detection, and greatly improve the detection efficiency. The drive component 8 and the clamping plate 13 can clamp glass panels of different sizes.

[0045] It should be noted that in this embodiment, the placement plate 4 is suspended and does not contact the top of the detection table 1.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, there are two clamping plates 13. The driving assembly 8 includes an external gear 81, which is rotatably mounted on the placement plate 4 relative to the through hole 10. Slider 83s are fixedly connected to both clamping plates 13, and the two sliders 83 pass through and slide on the placement plate 4. Two connecting rods 82 have their first ends movably mounted on the external gear 81, and their second ends are movably connected to the two sliders 83 respectively. A second rotating shaft 84 is rotatably mounted on the placement plate 4. A driving gear 85 that meshes with the external gear 81 is sleeved and fixedly installed on the second rotating shaft 84. The placement plate 4 is provided with a worm gear mechanism 86 that drives the second rotating shaft 84 to rotate. Specifically, in this embodiment, the placement plate 4... The upper part is provided with a sliding groove for the slider 83 to slide through. The structure, installation position and working principle of the worm gear mechanism 86 are all existing technologies. The worm gear is sleeved and fixedly installed on the second rotating shaft 84. The inner hole of the external gear 81 is larger than the diameter of the through hole 10. When adjusting the position of the two clamping plates 13, the second rotating shaft 84 is driven to rotate through the worm gear mechanism 86, which drives the drive gear 85 to mesh with the external gear 81, so that the external gear 81 makes a circular motion. The external gear 81 pushes the slider 83 to slide linearly through the connecting rod 82, so as to realize the synchronous movement of the two clamping plates 13 towards each other or away from each other, and complete the clamping and release of the glass panel. The worm gear transmission has a self-locking function to ensure the stability of the clamping state.

[0047] In this embodiment, as Figure 6 and Figure 7 As shown, both clamping plates 13 are equipped with buffer components 9. The buffer component 9 includes a movable plate 91, which is movably disposed within the clamping plate 13. The clamping plate 13 is provided with a movable groove 95 for the movable plate 91 to move. A spring 94 is provided in the movable groove 95 to abut against the movable plate 91. A movable rod 92 is fixedly mounted on the movable plate 91 at one end and extends to the outside of the clamping plate 13 and is fixedly mounted with a buffer plate 93 at the other end. Specifically, when the clamping plate 13 contacts the glass panel, the buffer plate 93 is squeezed, causing the movable rod 92 to retract into the movable groove 95, compressing the spring 94 to generate a buffering force. The elastic deformation of the spring 94 absorbs the impact force during the clamping process, preventing the glass from breaking due to rigid contact. The buffer component 9 protects the glass and reduces the defect rate, while extending the service life of the clamping plate 13 and reducing maintenance costs.

[0048] In this embodiment, as Figure 4 and Figure 6As shown, buffer pad 15 and anti-slip pad 14 are fixedly installed on buffer plate 93 and placement plate 4 respectively. Specifically, buffer pad 15 is made of soft material (such as silicone) to further disperse contact pressure; anti-slip pad 14 increases the friction between glass and placement plate 4 to prevent glass from sliding during detection and causing optical path deviation.

[0049] In this embodiment, as Figure 1 , Figure 8 and Figure 9As shown, it also includes a mounting bracket 11, which is fixedly mounted on the testing table 1. A cleaning assembly 5 is provided on the mounting bracket 11 opposite the placement plate 4. The cleaning assembly 5 includes a cylinder 51, a cleaning plate 52, a scraper 53, and a wiping cotton pad 54. The cylinder 51 is mounted on the mounting bracket 11. The extension end of the cylinder 51 is fixedly mounted on the cleaning plate 52. The scraper 53 and the wiping cotton pad 54 are fixedly mounted opposite each other at the bottom of the cleaning plate 52. An extension plate 17 is detachably connected to the cleaning plate 52. An insert block 18 is fixedly mounted on the extension plate 17. The cleaning plate 52 has an insertion hole 20 for the insert block 18 to be inserted into. A positioning hole 21 is provided through the insert block 18. The cleaning plate 52 is positioned relative to the positioning hole 21. A positioning bolt 19 is threaded onto the upper part of the mounting bracket 11. A lifting assembly 7, which drives the cleaning assembly 5 to rise and fall, is provided on the mounting bracket 11. The lifting assembly 7 includes multiple guide rods 73, which are fixedly mounted on the mounting bracket 11. A lifting plate 71 is sleeved on and slidably connected to the multiple guide rods 73. A cylinder 51 is fixedly mounted on the lifting plate 71. An adjusting bolt 72 passes through and is threaded onto the mounting bracket 11. The adjusting bolt 72 is rotatably mounted on the lifting plate 71. Limit plates 16 are fixedly mounted on each of the multiple guide rods 73. Specifically, in this embodiment, the cleaning assembly 5 is not set in the same position as the light source emitting mechanism 23. The scraper 53 and the wiping cotton block 54 on the cleaning plate can be placed with the cleaning assembly 53. The glass panel on plate 4 is in close contact with the glass. A scraper 53 and a wiping cotton pad 54 are positioned one behind the other on the cleaning plate. The scraper 53 preferentially contacts the glass panel. The extension plate 17 is also equipped with a scraper 53 and a wiping cotton pad 54. When cleaning the glass panel, a cylinder 51 drives the cleaning plate 52 towards the placement plate 4, causing the scraper 53 and wiping cotton pad 54 to contact the glass surface. The scraper 53 first removes larger particles of impurities, and the wiping cotton pad 54 then performs fine cleaning, ensuring that the glass surface is free of stains that could affect transmittance testing. This achieves automatic cleaning before testing, reduces manual intervention, improves efficiency, avoids interference from stains on transmittance data, and improves testing accuracy. Adjustments are required when necessary. When adjusting the length of the cleaning plate, the extension plate 17 is inserted into the insertion hole 20 of the cleaning plate 52 via the insert block 18, and fixed by the positioning bolt 19 passing through the positioning hole 21. When disassembling, the bolt can be loosened to replace the extension plate 17 or cleaning component of different specifications. The modular design makes it easy to adapt to different sizes of glass, and the cleaning component can be quickly replaced, reducing maintenance costs and extending the service life of the equipment. When it is necessary to adjust the height of the cleaning component 5, the lifting plate 71 is slid up and down along the guide rod 73 by rotating the adjusting bolt 72 and through the threaded transmission, thereby adjusting the initial height of the cleaning component 5. The limit plate 16 prevents the lifting plate 71 from overtraveling, ensuring safe operation and further improving the versatility of the device.

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a support ring 12 is fixedly installed on the testing table 1 relative to multiple connecting plates 3. A pulley 22 that fits against the support ring 12 is movably connected to the bottom of the connecting plate 3. Specifically, in this embodiment, the pulley 22 is rotatably arranged at the bottom of the connecting plate 3. The pulley 22 is a universal wheel. The arrangement of the support ring 12 and the pulley 22 facilitates the improvement of the stability of the connecting plate 3 and the placement plate 4.

[0051] Furthermore, in this embodiment, the electrical devices such as cylinder 51, intermittent drive mechanism 6 of the grooved wheel, light source emitting mechanism 23 and photodetector 24 can be controlled by external control devices, and their wiring connections and working principles are all existing technologies.

[0052] Working principle:

[0053] In the initial state, the intermittent drive mechanism 6 of the Geneva wheel stops the first rotating shaft 2 at the initial position, with one of the placement plates 4 aligned with the loading position. The operator or robotic arm places the glass panel to be inspected on the placement plate 4, aligning its inspection position with the central through hole 10. Then, the worm gear mechanism 86 drives the second rotating shaft 84 to rotate, causing the drive gear 85 to mesh with the external gear 81, making the external gear 81 perform circular motion. The external gear 81 pushes the slider 83 to slide linearly through the connecting rod 82, realizing the synchronous opposite movement of the two clamping plates 13, so that the clamping plates 13 clamp the glass panel. After loading is completed, The intermittent drive mechanism 6 of the grooved wheel starts working. The cylindrical pin of the driving wheel engages with the radial groove of the driven grooved wheel, driving the first rotating shaft 2 to rotate. The first rotating shaft 2 drives the connecting plate 3 and the placement plate 4 to rotate, each rotation at a fixed angle. After rotation stops, it first rotates to the cleaning assembly 5, driving the cleaning plate 52 towards the placement plate 4 via the cylinder 51, so that the scraper 53 and the wiping cotton 54 contact the glass surface. The scraper 53 first removes larger particles of impurities, and the wiping cotton 54 then performs fine cleaning, ensuring that the glass surface is free of stains that could affect the light transmittance test. Afterward, it continues to rotate, and the placement plate 4 carrying the glass... The light source emitting mechanism 23 and the photodetector 24 are precisely aligned at the detection station. The central through-hole 10 of the placement plate 4 is precisely coaxial with the light source emitting mechanism 23 and the photodetector 24, ensuring that light passes perpendicularly through the glass panel. The light source emitting mechanism 23 (such as an LED light source or laser emitter) emits a beam of light of a specific wavelength, which passes through the through-hole 10 area of ​​the glass panel. The light passing through the glass is received by the photodetector 24, converted into an electrical signal, and transmitted to the data processing system. The detection data is stored in the system and can be simultaneously displayed on the operating interface or transmitted to the production management system. The mechanism restarts, moving the tested glass panel away from the testing station while simultaneously moving the next glass panel to be tested to the testing position. Repeating the above steps enables rapid testing of multiple glass panels. The glass panel rotates back to the unloading station with the placement plate 4, the drive component 8 reverses its direction, the clamping plate 13 releases the glass, and the operator or robotic arm removes the tested glass, places a new sample to be tested, and enters the next cycle. The overall structure and operation steps are simple, enabling multi-station cyclic testing and significantly improving testing efficiency. The drive component 8 and clamping plate 13 can clamp glass panels of different sizes.
