Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and particularly to a device for detecting the deflection of a glass substrate. Background Art

[0002] The magnitude of the deflection of a glass substrate is directly related to its quality. If the deflection of the glass substrate is too large, the breakage rate during subsequent processing will increase. Therefore, in order to ensure the quality of the glass substrate, it is necessary to detect the deflection of the glass substrate. In the prior art, it is necessary to manually carry the deflection pads onto the platform first, and then place the glass substrate sample to be measured on the deflection pads for deflection measurement. The measurement results are likely to vary due to different operations of the detection personnel, making it difficult to ensure the consistency of the test results, and the detection process is laborious and cumbersome. Summary of the Invention

[0003] To solve the technical problems existing in the background art, the present invention proposes a device for detecting the deflection of a glass substrate.

[0004] A device for detecting the deflection of a glass substrate includes: a platform, a support bar assembly, a cylinder assembly, a positioning block assembly, and a measuring ruler. Two parallel first grooves are formed on the top surface of the platform. The cylinder assembly is installed on the platform below the first grooves. The support bar assembly includes two support bars connected to the cylinder assembly and capable of being received in the first grooves. The positioning block assembly includes a plurality of positioning blocks vertically connected to the top surface of the platform. When the side wall of the glass substrate abuts against the positioning blocks and is placed on the top surface of the platform, the two support bars can be symmetrically distributed on both sides of the central axis of the glass substrate. The cylinder assembly can drive the two support bars carrying the glass substrate on their top surfaces to extend out of the first grooves to a first position. At the first position, the lowest point of the glass substrate should be higher than the top surface of the platform. The measuring ruler is used to measure the sag height of the lowest point of the glass substrate at the first position.

[0005] Preferably, the positioning blocks are distributed and connected to the top surface of the platform along two sides of the glass substrate placed on the platform that are perpendicular to each other.

[0006] Preferably, the support bar assembly further includes shock-absorbing rubber strips, and the shock-absorbing rubber strips are attached to the top surfaces of the support bars.

[0007] Preferably, the top surface of the shock-absorbing rubber strip has anti-slip patterns.

[0008] Preferably, the platform further has auxiliary measurement platforms extending outward from both ends of the support bars and perpendicular to the support bars, and the top surfaces of the auxiliary measurement platforms are flush with the top surface of the platform.

[0009] Preferably, the device further includes a control button assembly installed on the peripheral side wall of the platform. The cylinder assembly includes a solenoid valve. The control button assembly includes a lifting control button, a lowering control button, and a stop button electrically connected to the solenoid valve, which can respectively control the extension, retraction, and locking of the piston rod of the cylinder assembly.

[0010] Preferably, the cylinder assembly further includes a first one-way valve, a first throttle valve, a second one-way valve, and a second throttle valve. The first one-way valve and the first throttle valve are connected in parallel on the air path between the rodless cavity of the cylinder assembly and the first air outlet of the solenoid valve. The conduction direction of the first one-way valve is from the first air outlet of the solenoid valve to the rodless cavity. The second one-way valve and the second throttle valve are connected in parallel on the air path between the rod chamber of the cylinder assembly and the second air outlet of the solenoid valve. The conduction direction of the second one-way valve is from the second air outlet of the solenoid valve to the rod chamber.

[0011] Preferably, the device further includes a measuring ruler storage box connected to the peripheral side wall or the bottom surface of the platform.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The support bars are directly arranged in a structure that can move up and down on the platform, eliminating the process of the tester manually moving the support bars, reducing the labor intensity of the tester, and improving the detection efficiency. In addition, since the distance between the support bars is constant, the consistency of the test data is also ensured. The positioning blocks can enable the operator to quickly and accurately find the accurate position for placing the glass substrate on the top surface of the platform. At this position, it can be ensured that the two support bars are symmetrically distributed on both sides of the central axis of the glass substrate, improving the working reliability of the device and the accuracy of the test data.

[0014] The positioning blocks are distributed and connected to the top surface of the platform along two sides perpendicular to the glass substrate placed on the platform. This arrangement of the positioning blocks can not only play a reliable positioning role but also leave gaps on the top surface of the platform to facilitate the picking and placing of the glass substrate.

[0018] The following will describe the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0019] Reference Figures 1 to 3 Figures 1 to 3 , a device for detecting the deflection of a glass substrate, comprising: a platform 1, a support bar assembly, a cylinder assembly 3, a positioning block assembly, and a measuring ruler 4. Two parallel first grooves 11 are formed on the top surface of the platform 1. The cylinder assembly 3 is installed on the platform 1 below the first grooves 11. The support bar assembly includes two support bars 2 connected to the cylinder assembly 3 and capable of being received in the first grooves 11. The positioning block assembly includes a plurality of positioning blocks 6 vertically connected to the top surface of the platform. When the side wall of the glass substrate 5 abuts against the positioning blocks 6 and is placed on the top surface of the platform 1, the two support bars 2 can be symmetrically distributed on both sides of the central axis of the glass substrate 5. The cylinder assembly 3 can drive the two support bars 2 carrying the glass substrate on the top surface to extend out of the first grooves 11 to a first position. At the first position, the lowest point of the glass substrate 5 should be higher than the top surface of the platform 1. The measuring ruler 4 is used to measure the sag height of the lowest point of the glass substrate 5 at the first position. In this embodiment, both the platform 1 and the measuring ruler 4 are made of wear-resistant and non-deformable stainless steel.

[0020] Directly setting the support bars 2 into a structure that can move up and down on the platform 1 eliminates the process of the tester manually moving the support bars 2, reduces the labor intensity of the tester, and improves the detection efficiency. In addition, since the distance between the support bars 2 is constant, the consistency of the test data is also ensured. The positioning blocks 6 can enable the operator to quickly and accurately find the accurate position for placing the glass substrate 5 on the top surface of the platform 1. At this position, the two support bars 2 can be symmetrically distributed on both sides of the central axis of the glass substrate 5, improving the working reliability of the device and the accuracy of the test data.

[0021] Reference Figure 1 、 Figure 2 Figure 2 , the positioning blocks 6 are distributed and connected to the top surface of the platform 1 along two sides of the glass substrate 5 placed on the platform 1 that are perpendicular to each other. In this embodiment, two positioning blocks are provided on one side of the glass substrate 5 parallel to the support bars 2, and one positioning block is provided on the other side of the glass substrate 5 perpendicular to the support bars 2. This arrangement of the positioning blocks 6 can not only play a reliable positioning role but also leave a gap on the top surface of the platform 1 for convenient placement and removal of the glass substrate 5.

[0022] Reference Figure 1 、 Figure 2 Figure 2 , the device further includes a shock-absorbing rubber strip 7. The shock-absorbing rubber strip 7 is attached to the top surface of the support bars 2. The shock-absorbing rubber strip 7 can effectively reduce the impact force of the support bars 2 driven by the cylinder assembly 3 on the glass substrate 5 and can better protect the glass substrate 5.

[0023] Reference Figure 1, the top surface of the shock-absorbing rubber strip 7 has anti-slip patterns 71 to increase the friction between the top surface of the shock-absorbing rubber strip 7 and the bottom surface of the glass substrate 5, effectively preventing the glass substrate 5 from sliding on the shock-absorbing rubber strip 7 and ensuring the working reliability of the device.

[0024] Referring to Figure 1 , the platform 1 also has auxiliary measuring tables 12 extending outward from both ends of the self-supporting strip 2 and perpendicular to the supporting strip 2. The top surface of the auxiliary measuring table 12 is flush with the top surface of the platform 1. The bottom surface of the measuring ruler 4 can be abutted against the top surface of the auxiliary measuring table 12 for deflection measurement, further ensuring the accuracy of the measurement result.

[0025] Referring to Figure 2 , it further includes a control button assembly 8. The control button assembly 8 is installed on the peripheral wall of the platform 1. The cylinder assembly 3 includes a solenoid valve 31. The control button assembly 8 includes a rising control button 81, a falling control button 82, and a stop button 83 electrically connected to the solenoid valve 31, which can respectively control the extension, retraction, and locking of the piston rod of the cylinder assembly 3.

[0026] Referring to Figure 3 , the cylinder assembly 3 further includes a first one-way valve 32, a first throttle valve 33, a second one-way valve 34, and a second throttle valve 35. The first one-way valve 32 and the first throttle valve 33 are connected in parallel on the air path between the rodless cavity of the cylinder assembly 3 and the first air outlet 311 of the solenoid valve. The conduction direction of the first one-way valve 32 is from the first air outlet 311 of the solenoid valve to the rodless cavity. The second one-way valve 34 and the second throttle valve 35 are connected in parallel on the air path between the rod cavity of the cylinder assembly 3 and the second air outlet 312 of the solenoid valve. The conduction direction of the second one-way valve 34 is from the second air outlet 312 of the solenoid valve to the rod cavity.

[0027] In practical applications, the air inlet of the solenoid valve 31 is connected to the air source 36. When the piston rod of the cylinder assembly 3 needs to extend, by pressing the rising control button 81, the valve between the air inlet and the first air outlet 311 of the solenoid valve 31 is opened. At this time, the high-pressure gas will flow into the rodless cavity through the first one-way valve 32 with almost no resistance, and the gas in the rod cavity can only be discharged through the second throttle valve 35. Thus, the extension speed of the piston rod can be controlled by adjusting the valve orifice size of the second throttle valve 35. When the piston rod retracts, similarly, the retraction speed of the piston rod can be controlled by adjusting the valve orifice size of the second throttle valve 35. Through the above adjustment and control, the rising and falling speeds of the two supporting strips 2 can be adjusted to be the same, and a speed that takes into account both efficiency and stability can be selected.

[0028] Referring to Figure 1 、 Figure 2 , the device further includes a measuring ruler storage box 9. The measuring ruler storage box 9 is connected to the peripheral wall or the bottom surface of the platform 1.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
