Description

Technical Field

[0001] The utility model relates to the technical field of glass detection, and more specifically, to a glass substrate thickness detection device. Background Art

[0002] Glass substrates are a key foundational material in the flat panel display industry, forming a fundamental component of liquid crystal display devices. In LCD panels, the glass substrate supports and protects the liquid crystal molecules while also serving as a carrier for the circuitry and pixel graphics. In real life, different devices require varying glass substrate thicknesses, while the same device often requires consistent thickness across all parts of the glass substrate.

[0003] Currently, glass substrate thickness detection devices primarily use optical measurement methods to measure glass thickness. This involves utilizing the principles of light refraction and reflection. A beam of light is directed obliquely onto the glass being measured. After being refracted by the glass, the beam is received by a photodiode, and a computer or single-chip microcomputer calculates the thickness. However, this detection method is highly susceptible to interference from external light, reducing detection accuracy. Furthermore, existing optical equipment is generally expensive, increasing production costs for manufacturers. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a glass substrate thickness detection device.

[0005] According to one aspect of the present invention, a glass substrate thickness detection device is provided, comprising a detection platform, a glass substrate being placed on the detection platform, the detection platform being rotatably mounted on a support seat, a connecting frame being vertically fixedly mounted on the support seat, a transverse fixing plate being fixedly mounted on the connecting frame, the fixing plate being connected to a pressure test block via a transverse moving component, the transverse moving component being used to laterally adjust the position of the pressure test block, the pressure test block being connected to a longitudinal moving component, the longitudinal moving component being used to adjust the height of the pressure test block.

[0006] This solution places the glass substrate to be tested on the testing platform. The transverse motion component is used to move the pressure test block above the glass substrate. The longitudinal motion component is then used to press the pressure test block against the glass substrate. The testing platform is then rotated to perform multi-point thickness testing on the glass substrate. When the pressure value transmitted by the pressure test block is normal, the glass substrate meets the thickness requirements and is qualified. Otherwise, it is unqualified. This device enables multi-point thickness testing on the same glass substrate, preventing uneven surface thickness on the same glass substrate, which could affect product quality. Furthermore, the longitudinal motion component can be used to test glass substrates of varying thicknesses, meeting the thickness testing requirements for glass substrates of varying specifications.

[0007] Preferably, the transverse moving component includes a slide groove, a slider, a screw rod and a nut. The fixed plate is provided with a transversely arranged slide groove. The slider is fixedly connected to the screw rod. The screw rod passes through the slide groove and is slidably connected to it. The screw rod is fixedly connected to the fixed plate through the nut.

[0008] Through this solution, a slide groove is provided on the fixed plate, and a screw rod on the slider is inserted into the slide groove and slides. When the slider moves to a specified position, a pair of nuts are used to fix the slider, thereby realizing thickness detection of multiple points on the glass substrate, reducing the uneven thickness of the glass substrate surface, and ensuring product quality.

[0009] Preferably, the longitudinal movement component includes a second slide groove, a connecting plate, a second screw and a second nut. The second screw is fixedly installed on the left and right sides of the slider. The second slide groove is vertically arranged on the connecting plate. The second screw passes through the second slide groove and is slidably connected to it. The second screw is threadedly connected to the second nut, and the connecting plate is fixedly connected to the pressure test block.

[0010] Through this solution, the thickness of the glass is calculated in advance, and the position of the connecting plate is adjusted according to the thickness of the glass. That is, the connecting plate slides up and down along the second screw. When it reaches the appropriate position, the position of the connecting plate is fixed with the second nut. At this time, the pressure test block just contacts the glass substrate to be tested. If the pressure value transmitted by the pressure test block is normal, it means that the thickness at this location meets the product requirements. If it is higher or lower than the normal value, it means that the thickness at this location does not meet the product requirements and is a defective product.

[0011] Preferably, the fixing plate and the connecting plate are both marked with scales.

[0012] Through this solution and the setting of the scale, the accuracy of the lateral and longitudinal movement of the pressure test block can be improved, thereby improving the accuracy of the glass substrate thickness detection.

[0013] Preferably, a mounting seat is fixedly installed between the two connecting plates, the mounting seat is located at the bottom of the connecting plates, and the pressure test block is fixedly installed at the bottom of the mounting seat.

[0014] Through this solution, the setting of the mounting base can not only better install the pressure test block, but also prompt the two connecting plates to adjust their positions synchronously, preventing the two connecting plates from affecting the final test results due to inconsistent adjustment heights.

[0015] Preferably, the detection platform is rotatably connected to the support seat via a bearing.

[0016] Through this solution, the detection platform is rotatably mounted on the support seat by means of bearings, which makes it easy to rotate the detection platform at any time when testing the glass thickness. When the position of the pressure test block is fixed, the detection platform can be rotated to detect the glass substrate along its circumferential direction, thereby increasing the number of glass detection points, eliminating the need for multiple repositioning, and improving the efficiency of detection.

[0017] The technical effect of the present utility model is that the glass substrate thickness detection device is not only free from interference from external light, thus improving detection accuracy and saving production costs, but also can meet the requirements for thickness detection of glass substrates of different specifications, thus expanding the scope of application. Moreover, the device can quickly detect multiple points on the glass substrate without the need for multiple positioning, thus improving the efficiency of glass substrate thickness detection.

[0028] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] Example

[0031] like Figures 1 to 4 As shown, the glass substrate thickness detection device in this embodiment includes a detection platform 1, on which a glass substrate is placed. The detection platform 1 is rotatably mounted on a support base 2, on which a connecting frame 3 is vertically fixedly mounted. A horizontal fixing plate 4 is fixedly mounted on the connecting frame 3. The fixing plate 4 is connected to a pressure test block 6 via a transverse movement component 5. The transverse movement component 5 is used to laterally adjust the position of the pressure test block 6. The pressure test block 6 is connected to a longitudinal movement component 7, which is used to adjust the height of the pressure test block 6. Specifically, the number of pressure test blocks 6 in this embodiment is multiple, which facilitates simultaneous testing of the thickness of the glass substrate and increases the detection range.

[0032] The glass substrate to be tested is placed on the testing platform 1. The transverse movement component 5 is used to move the pressure test block 6 to the top of the glass substrate. The longitudinal movement component 7 is then used to press the pressure test block 6 against the glass substrate. The testing platform 1 is then rotated to perform multi-point thickness testing on the glass substrate. When the pressure value transmitted by the pressure test block 6 is normal, it means that the thickness of the glass substrate meets the requirements and is a qualified product. Otherwise, it is a failed product. This device realizes multi-point thickness testing on the same glass substrate, avoiding the uneven surface thickness of the same glass substrate, which affects the quality of the product. At the same time, the longitudinal movement component 7 can also be used to test glass substrates of different thicknesses, meeting the thickness testing requirements of glass substrates of different specifications.

[0033] Furthermore, the transverse moving component 5 includes a slide groove 51, a slider 52, a screw 53 and a nut 1. The fixed plate 4 is provided with a transversely arranged slide groove 51, the slider 52 is fixedly connected to the screw 53, the screw 53 passes through the slide groove 51 and is slidably connected thereto, and the screw 53 is fixedly connected to the fixed plate 4 through the nut 1.

[0034] A slide groove 51 is provided on the fixed plate 4, and a screw 53 on the slider 52 is inserted into the slide groove 51 and slides. When the slider 52 moves to the specified position, a pair of nuts are used to fix the slider 52, thereby realizing thickness detection of multiple points on the glass substrate, reducing the situation of uneven thickness on the surface of the glass substrate, and ensuring product quality.

[0035] Furthermore, the longitudinal movement component 7 includes a second slide groove 71, a connecting plate 72, a second screw 73 and a second nut 74. The second screw 73 is fixedly installed on the left and right sides of the slider 52. The second slide groove 71 is vertically arranged on the connecting plate 72. The second screw 73 passes through the second slide groove 71 and is slidably connected thereto. The second screw 73 is threadedly connected to the second nut 74, and the connecting plate 72 is fixedly connected to the pressure test block 6.

[0036] Calculate the thickness of the glass in advance and adjust the position of the connecting plate 72 according to the thickness of the glass. That is, the connecting plate 72 slides up and down along the screw 2 73. When it reaches the appropriate position, use the nut 2 74 to fix the position of the connecting plate 72. At this time, the pressure test block 6 just contacts the glass substrate to be tested. If the pressure value transmitted by the pressure test block 6 is normal, it means that the thickness at this location meets the product requirements. If it is higher or lower than the normal value, it means that the thickness at this location does not meet the product requirements and is a defective product.

[0037] Furthermore, the fixing plate 4 and the connecting plate 72 are both marked with scales 8 .

[0038] The setting of the scale 8 can improve the accuracy of the lateral and longitudinal movement of the pressure test block 6, thereby improving the accuracy of the glass substrate thickness detection.

[0039] Furthermore, a mounting seat 9 is fixedly installed between the two connecting plates 72 . The mounting seat 9 is located at the bottom of the connecting plates 72 , and the pressure test block 6 is fixedly installed at the bottom of the mounting seat 9 .

[0040] The setting of the mounting seat 9 can not only better install the pressure test block 6, but also prompt the two connecting plates 72 to adjust their positions synchronously, preventing the two connecting plates 72 from affecting the final test results due to inconsistent adjustment heights.

[0041] Furthermore, the detection platform 1 is rotatably connected to the support base 2 via a bearing 10 .

[0042] The detection platform 1 is rotatably mounted on the support base 2 by means of a bearing 10, so that the detection platform 1 can be rotated at any time when the glass thickness is detected. When the position of the pressure test block 6 is fixed, the detection platform 1 can be rotated to detect the glass substrate along its circumferential direction, thereby increasing the number of glass detection points, eliminating the need for multiple repositioning and improving the detection efficiency.

[0043] The working principle of this embodiment is as follows:

[0044] According to the production thickness of the batch of glass substrates, the connecting plate 72 is slid up and down. Under the action of the scale 8, the connecting plate 72 is adjusted to the appropriate height. Then, the position of the connecting plate 72 is fixed using the second nut 74. The glass substrate to be tested is then placed on the testing platform 1. The slider 52 is slid. When the pressure test block 6 contacts the predetermined position of the glass substrate, the position of the slider 52 is fixed using the second nut. The testing platform 1 can be rotated so that the pressure test block 6 performs a thickness test on the glass substrate along the circumferential direction. The position of the slider 52 can also be adjusted multiple times according to actual testing needs to achieve a comprehensive test of the glass substrate. When the pressure value transmitted by the pressure test block 6 is normal, it means that the thickness of the glass substrate meets the requirements and is qualified. Otherwise, it is unqualified.

[0045] The technical effect of the embodiment of the utility model is that the glass substrate thickness detection device is not only not affected by external light, improves the detection accuracy, and saves production costs, but also can meet the requirements of thickness detection of glass substrates of different specifications, expanding the scope of application. In addition, the device can quickly detect multiple points on the glass substrate without multiple positioning, thereby improving the efficiency of glass substrate thickness detection.

Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
