[0001] The present invention belongs to the technical field of glass performance testing, and more specifically, relates to a misalignment bending test device for ultra-thin flexible glass. Background Art

[0002] In recent years, flexible display technology has developed rapidly, and foldable flexible screens have gradually gained market favor. When the glass thickness is less than 0.1 mm, it has bendability. The thinner the thickness, the better the bending performance. Usually, glass with a thickness less than 0.1 mm is called ultra-thin flexible glass UTG (Ultra Thin Glass). Ultra-thin flexible glass has good bending properties, good transparency, heat resistance stability, high hardness, etc. Currently, glass manufacturers have produced ultra-thin flexible glass with a thickness of 0.03 mm, and its minimum bending radius reaches 1 mm.

[0003] Ultra-thin flexible glass UTG is generally used for foldable flexible screen covers, so it has high requirements for its bending performance and service life. In order to detect the bending performance and service life of ultra-thin flexible glass, a misalignment bending test device for ultra-thin flexible glass is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a misalignment bending test device for ultra-thin flexible glass, which can detect the bending performance and service life of ultra-thin flexible glass.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a misalignment bending test device for ultra-thin flexible glass, including: A workbench and two working mechanisms arranged oppositely. The two working mechanisms are respectively defined as a fixed working mechanism and a moving working mechanism. A fixed seat is arranged at the lower end of the fixed working mechanism, and a transverse moving component is arranged at the lower end of the moving working mechanism. The transverse moving component and the fixed seat are both fixed on the workbench, and the transverse moving component is used to drive the moving working mechanism to approach or move away from the fixed working mechanism; The working mechanism includes a connecting frame fixed on the transverse moving component or the fixed seat. A longitudinal moving component is arranged on the connecting frame. Clamping parts are installed on the opposite sides of the two longitudinal moving components. A detection unit for detecting the glass breakage state is installed at the upper end of any one of the clamping parts. The detection unit is electrically connected to the transverse moving component and the longitudinal moving component.

[0006] In a possible implementation manner, the workbench includes a chassis. An electric control system is built in the chassis. The transverse moving component and the fixed seat are both fixed on the upper end surface of the chassis. The electric control system is used to receive the detection signal of the detection unit and control the start and stop of the transverse moving component and the longitudinal moving component.

[0007] In a possible implementation, a plurality of feet are provided at the bottom of the chassis, an input / output unit electrically connected to the electric control system is provided at the front side of the chassis, and exhaust fans are respectively provided on both sides of the chassis.

[0008] In a possible implementation, the transverse movement component includes a mounting plate, a transverse linear module, and a transverse drive motor. The mounting plate is fixed to the workbench, the transverse linear module is transversely arranged on the upper end surface of the mounting plate, the mobile operation mechanism is fixed to the transverse linear module, and the transverse drive motor is connected to the transverse linear module to drive the mobile operation mechanism to approach or move away from the fixed operation mechanism through the transverse linear module.

[0009] In a possible implementation, the longitudinal movement component includes a longitudinal linear module and a longitudinal drive motor. The longitudinal linear module is longitudinally arranged on the connecting frame, and the two clamping parts are respectively arranged on the opposite sides of the two longitudinal linear modules. The longitudinal drive motor is connected to the longitudinal linear module to drive the clamping part to lift through the longitudinal linear module.

[0010] In a possible implementation, adjusting plates are provided on the opposite sides of the two longitudinal linear modules, and the clamping parts are respectively mounted on the adjusting plates on the corresponding sides. The adjusting plates are used to adjust the parallelism of the two clamping parts.

[0011] In a possible implementation, the clamping part includes a clamping plate. The clamping plate is mounted on the adjusting plate on the same side, and the opposite sides of the two clamping plates form parallel clamping surfaces.

[0012] In a possible implementation, distance measuring sensors are provided on the two clamping plates for measuring the distance between the two clamping surfaces.

[0013] In a possible implementation, the detection unit is an optoelectronic detection probe or an ultrasonic detection probe.

[0014] The beneficial effect of an ultra-thin flexible glass dislocation bending test device provided by the present invention is that, compared with the prior art, the independent movement of the transverse movement component or the linkage mode of the transverse movement component in cooperation with the longitudinal movement component can realize the detection of three states of ultra-thin flexible glass.

[0025] Please refer to Figure 1 and Figure 2 A thin and flexible glass misalignment bending test device provided by the present invention will now be described. A thin and flexible glass misalignment bending test device includes a workbench and two working mechanisms arranged oppositely. The two working mechanisms are respectively defined as a fixed working mechanism and a moving working mechanism. A fixed seat 13 is provided at the lower end of the fixed working mechanism, and a transverse movement component 2 is provided at the lower end of the moving working mechanism. Both the transverse movement component 2 and the fixed seat 13 are fixed on the workbench. The transverse movement component 2 is used to drive the moving working mechanism to approach or move away from the fixed working mechanism; the working mechanism includes a connecting frame 3 fixed on the transverse movement component 2 or the fixed seat 13. A longitudinal movement component 4 is provided on the connecting frame 3. Clamping parts are installed on the opposite sides of the two longitudinal movement components 4. A detection unit 5 for detecting the glass breakage state is installed at the upper end of any one of the clamping parts. The detection unit 5 is electrically connected to the transverse movement component 2 and the longitudinal movement component 4.

[0026] Compared with the prior art, the ultra-thin flexible glass dislocation bending test device provided by the present invention can detect three states of ultra-thin flexible glass by the independent movement of the transverse movement member 2 or the linkage mode of the transverse movement member 2 cooperating with the longitudinal movement member 4.

[0027] Detection of the ultimate bending radius of ultra-thin flexible glass: Clamp the ultra-thin flexible glass between two clamping parts. The transverse movement member 2 drives the moving operation mechanism to gradually approach the fixed operation mechanism. The ultra-thin flexible glass is gradually bent, and the bending radius of the ultra-thin flexible glass gradually decreases until the ultra-thin flexible glass breaks. After the detection unit 5 detects the glass break state, the transverse movement member 2 is stopped at the same time. The ultimate bending radius of the ultra-thin flexible glass is calculated through the gap between the two clamping parts.

[0028] Detection of the bending life of ultra-thin flexible glass: Clamp the ultra-thin flexible glass between two clamping parts. Set the preset displacement value of the transverse movement member 2, and move the transverse movement member 2 back and forth horizontally according to the preset displacement value, so that the moving operation mechanism repeatedly approaches and moves away from the fixed operation mechanism. At the same time, the ultra-thin flexible glass is repeatedly bent until it breaks. After the detection unit 5 detects the glass break state, the transverse movement member 2 is stopped at the same time, and the number of bends read at this time is the bending life of the ultra-thin flexible glass.

[0029] Detection of the dislocation bending of ultra-thin flexible glass: Clamp the ultra-thin flexible glass between two clamping parts. Set the preset displacement value of the transverse movement member 2. After moving horizontally to a predetermined position according to the preset displacement value, the transverse movement member 2 stops. The two longitudinal movement members 4 alternately rise and fall, driving the ultra-thin flexible glass to perform a dislocation test between the clamping parts with a certain bending radius and automatically record the number of cycles. When the glass breaks, the detection unit 5 senses it and causes the longitudinal movement member 4 to stop moving. The number of cycles read at this time is the dislocation bending life of the ultra-thin flexible glass.

[0030] The ultra-thin flexible glass dislocation bending test device provided by the present invention can respectively complete the detection of the ultimate bending radius of ultra-thin flexible glass, the detection of the bending life, and the detection of the dislocation bending, and realize the detection of the bending performance and service life of ultra-thin flexible glass.

[0031] Please refer to Figure 1, the workbench includes a chassis 1 with an electric control system built therein. Both the transverse moving component 2 and the fixed seat 13 are fixed to the upper end surface of the chassis 1. The electric control system is used to receive the detection signals from the detection unit 5 and control the start and stop of the transverse moving component 2 and the longitudinal moving component 4. By firmly arranging both the transverse moving component 2 and the fixed seat 13 on the upper end surface of the chassis 1 and combining with the design of the chassis 1 with an in-built electric control system, a compact structural layout is created. This integrated design method greatly saves the floor space of the workbench. Especially in production workshops, laboratories or workrooms with limited space, it can more reasonably plan the site, accommodate more supporting equipment, and provide convenience for enterprises to expand their business or upgrade their production scale. The electric control system built in the chassis 1 provides a relatively enclosed and stable operating environment for precision electronic components, effectively shielding external dust, moisture and electromagnetic interference, reducing the risk of system failures, and ensuring long-term stable operation. The electric control system uniformly regulates the transverse moving component 2 and the longitudinal moving component 4, enabling perfect coordinated actions between them and avoiding motion conflicts caused by signal delays or inconsistencies between different control units.

[0032] Specifically, multiple floor feet 11 are provided at the bottom of the chassis 1, an input / output unit 12 electrically connected to the electric control system is provided at the front side of the chassis 1, and exhaust fans are respectively provided on both sides of the chassis 1. The frame of the chassis 1 is welded by high-strength steel pipes, having the advantages of high strength and good stability. The multiple floor feet 11 provided at the bottom of the chassis 1 can effectively enhance the stability of the workbench when placed, making it not easily shake or displace due to slight unevenness of the ground or vibrations during the working process, ensuring the accuracy and reliability of the workbench during operation. At the same time, the adjustable design of the floor feet 11 can flexibly adjust the height and levelness of the chassis 1 according to different ground conditions and usage requirements, enabling the workbench to better adapt to various working environments and improving its versatility and applicability. The input / output unit 12 electrically connected to the electric control system provided at the front side of the chassis 1 provides a convenient interface for data transmission and power supply between the workbench and external devices or systems. Operators can easily connect external sensors, control devices, computers, etc. to the workbench to achieve real-time data transmission and interaction, facilitating the monitoring and adjustment of the working state of the workbench. The exhaust fans respectively provided on both sides of the chassis 1 can effectively promote the air circulation inside the chassis 1, timely discharge the heat generated by heat-generating components such as the electric control system out of the chassis 1, and avoid equipment overheating caused by heat accumulation, which affects its performance and service life. Good heat dissipation design helps to maintain the stable operation of the electric control system, reduce the risk of failures caused by overheating, and improve the reliability and stability of the workbench, especially suitable for scenarios of long-term continuous operation.

[0033] Specifically, the transverse movement component 2 includes a mounting plate 23, a transverse linear module 22, and a transverse drive motor 21. The mounting plate 23 is fixed to the workbench. The transverse linear module 22 is horizontally arranged on the upper end surface of the mounting plate 23. The mobile operation mechanism is fixed to the transverse linear module 22. The transverse drive motor 21 is connected to the transverse linear module 22 to drive the mobile operation mechanism to approach or move away from the fixed operation mechanism through the transverse linear module 22. The mounting plate 23 of the transverse movement component 2 is fixed to the workbench, providing a stable mounting foundation for the transverse linear module 22 and the transverse drive motor 21. This structural design enables the transverse movement component 2 to be compactly integrated into the workbench, occupying less space and being conducive to optimizing the overall layout of the workbench. At the same time, the fixing method of the mounting plate 23 is simple and reliable, facilitating installation and disassembly on the workbench and convenient for equipment debugging, maintenance, and upgrading. The connection method between the transverse drive motor 21 and the transverse linear module 22 ensures efficient power transmission and reduces power loss.

[0034] Specifically, the longitudinal movement component 4 includes a longitudinal linear module 42 and a longitudinal drive motor 41. The longitudinal linear module 42 is longitudinally arranged on the connecting frame 3. The two clamping parts are respectively arranged on the opposite sides of the two longitudinal linear modules 42. The longitudinal drive motor 41 is connected to the longitudinal linear module 42 to drive the clamping parts to move up and down through the longitudinal linear module 42. The longitudinal drive motor 41 drives the two clamping parts to move up and down synchronously through the longitudinal linear module 42, ensuring the coordination and consistency of the two clamping parts during movement.

[0035] Preferably, adjustment plates 43 are arranged on the opposite sides of the two longitudinal linear modules 42. The clamping parts are respectively mounted on the adjustment plates 43 on the corresponding sides. The adjustment plates 43 are used to adjust the parallelism of the two clamping parts. Adjustment bolts are respectively arranged at the corners of the adjustment plates 43. The parallelism of the two clamping parts is adjusted by rotating the adjustment bolts. This method can achieve fine adjustment of the parallelism. Since the adjustment bolts act on the corners of the adjustment plates 43, very subtle changes in the attitude of the adjustment plates 43 can be made when rotating, thereby precisely adjusting the position of the clamping parts. This fine-tuning function can ensure that the two clamping parts reach a nearly perfect parallel state, greatly improving the operation accuracy and the yield rate of products. When it is found that the parallelism of the two clamping parts deviates, the problem can be solved by adjusting the adjustment bolts without replacing the entire adjustment plate 43 or the clamping components, greatly reducing the maintenance cost.

[0036] Specifically, the clamping part includes a clamping plate 44, which is mounted on the adjusting plate 43 on the same side. The opposite sides of the two clamping plates 44 form parallel clamping surfaces, which can provide uniform and stable clamping force for the ultra-thin flexible glass. When clamping the ultra-thin flexible glass, the parallel clamping surfaces can fully contact both ends of the ultra-thin flexible glass to ensure uniform force distribution. The clamping plate 44 is mounted on the adjusting plate 43. Combining with the parallelism adjustment function of the adjusting plate 43, it can adapt to ultra-thin flexible glass of different specifications.

[0037] In addition, distance measuring sensors are provided on the two clamping plates 44 for measuring the distance between the two clamping surfaces. The distance measuring sensors can measure the distance change between the two clamping surfaces in real time and accurately. By analyzing and processing these distance data, the distance of the ultra-thin flexible glass in any state between the two clamping plates 44 can be intuitively obtained, and then its bending state can be accurately determined. By deeply analyzing the distance data of the ultra-thin flexible glass in different states obtained by the distance measuring sensors, the manufacturer can better understand the mechanical properties and deformation laws of the ultra-thin flexible glass.

[0038] Specifically, the detection unit 5 is a photoelectric detection probe or an ultrasonic detection probe. Whether it is a photoelectric detection probe or an ultrasonic detection probe as the detection unit 5, it brings unique advantages to the workbench, enabling it to operate more efficiently, accurately and reliably in the process of processing work objects such as ultra-thin flexible glass.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
