[0002] With the rapid development of foldable phones, ultra-thin glass cover plates have attracted more and more attention from listed companies in the industry, and there is a demand for expansion of their production capacity. Non-uniform thickness flexible glass is a new type of foldable glass material, which consists of non-uniform thickness flexible glass film and flexible electronic devices. Compared with traditional glass, non-uniform thickness flexible glass has higher flexibility and plasticity, and can achieve various forms of folding and bending while maintaining high transparency and strength. Non-uniform thickness flexible glass has become one of the important development trends of glass. However, non-uniform thickness flexible glass is a transparent object, and the size of the groove part is very small.

With the market demand, higher and higher requirements are placed on product production efficiency. At present, relying on the naked eye to distinguish the groove surface of non-uniform thickness flexible glass during operation can no longer meet the needs of producing large quantities of products.

The motor, as a driving force, can drive the first screw to rotate, thereby driving the first pressure block to move downward to squeeze the glass, thereby testing the flexibility of the glass.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in view of the shortcomings of the existing technology, a non-uniform thickness flexible glass surface detection device with a simple structure is provided, which can accurately and quickly identify the grooved surface of non-uniform thickness flexible glass, reduce the misjudgment rate of the grooved surface, avoid operators sticking it upside down, reduce the rework rate and scrap rate, improve work efficiency, and reduce labor costs and time costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0013] When the non-uniform thickness flexible glass is placed on the device workbench with the grooved surface facing upward for testing, the center of the non-uniform thickness flexible glass is the groove portion, and the horizontal height of the groove portion is lower than the edge position of the non-uniform thickness flexible glass in all directions.

DETAILED DESCRIPTION

[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0023] As attached Figure 1 , Attachment Figure 2 As shown, the utility model is a device for detecting the surface of non-uniform thickness flexible glass. The non-uniform thickness flexible glass 14 includes a flat surface 1 and a grooved surface 2. The non-uniform thickness flexible glass surface detection device includes a device workbench 3. A detection and identification instrument 4 is arranged above the device workbench 3. The detection and identification instrument 4 includes a detection and identification probe 5. The above structure proposes an improved technical solution in view of the deficiencies in the existing technology. When the structure is set up, the device workbench 3 is set up in view of the characteristics that the non-uniform thickness flexible glass 14 includes a flat surface 1 and a grooved surface 2. The device workbench 3 is used to place the non-uniform thickness flexible glass 14 to be detected. A detection and identification instrument 4 is arranged above the device workbench 3. The detection and identification instrument 4 includes a detection and identification probe 5. The detection and identification probe 5 can detect the distance data between the probe tip and the non-uniform thickness flexible glass 14, and judge whether the non-uniform thickness flexible glass 14 has the flat surface 1 facing upward or the grooved surface 2 facing upward based on the distance. To determine the grooved surface 2 of the non-uniform thickness flexible glass 14, the non-uniform thickness flexible glass 14 is placed on the workbench. When the non-uniform thickness flexible glass 14 is placed on the workbench 3 with its flat surface 1 facing upward, the center 9 of the non-uniform thickness flexible glass and the edges 10 extending in all directions from the center 9 are in the same plane. At this point, the detection and identification instrument 4 displays a signal indicating that the non-uniform thickness flexible glass 14 has a flat surface facing upward. When the non-uniform thickness flexible glass 14 is placed on the workbench 3 with its grooved surface 2 facing upward, the center 9 of the non-uniform thickness flexible glass 14 forms a groove 11, which is lower than the edges 10 in all directions of the non-uniform thickness flexible glass 14. At this point, the detection and identification instrument 4 displays a signal indicating that the non-uniform thickness flexible glass 14 has a grooved surface 2 facing upward. This allows the determination of whether the non-uniform thickness flexible glass 14 has a flat surface 1 or a grooved surface 2 facing upward with a single test. The operator then removes the non-uniform thickness flexible glass 14 for lamination. In this way, the flat surface and grooved surface of non-uniform thickness flexible glass can be effectively distinguished, and the error rate of personnel in identifying the front and back surfaces of non-uniform thickness flexible glass can be reduced. The entire device has a simple structure and is easy for personnel to operate. The grooved surface (front) and flat surface (back) of the product can be identified and marked in the initial stage of the product. The detection device can also be placed at the bonding site for on-site detection and bonding, thereby improving bonding efficiency. The non-uniform thickness flexible glass surface detection device described in the utility model has a simple structure and can accurately and quickly distinguish the grooved surface of non-uniform thickness flexible glass, thereby reducing the error rate of the grooved surface, avoiding operators from bonding the glass upside down, reducing the rework rate and scrap rate, improving work efficiency, and reducing labor costs and time costs.

[0024] A crossbeam 7 is mounted on a bracket 6 on the side of the workbench 3, a working beam 8 is mounted on the crossbeam 7, and the detection and identification instrument 4 is mounted on the working beam 8. This structure allows the detection and identification instrument 4 to be mounted on the working beam 8, while the detection and identification probe 5 is positioned above the workbench. This facilitates reliable front and back inspection of flexible glass of varying thicknesses on the workbench.

[0025] The working beam 8 is movably mounted in the chute on the side of the crossbeam 7 via a slider, and the working beam 8 is arranged parallel to the device workbench 3. The upper portion of the detection and identification instrument 4 is movably connected to the chute at the lower portion of the working beam 8 via a slider. With the above structure, the working beam 8 can move relative to the crossbeam 7 to adjust the position of the working beam, thereby driving the detection and identification instrument 4 to move forward and backward relative to the device workbench 3. The detection and identification instrument 4 can move relative to the working beam 8 to adjust the position of the detection and identification instrument 4, thereby driving the detection and identification instrument 4 to move left and right relative to the device workbench 3. This meets the needs of different sizes of glass to be inspected and improves the versatility of the device.

[0026] The working beam 8 is provided with a working beam rack, and the crossbeam 7 is provided with a crossbeam motor. The crossbeam motor drive gear of the crossbeam motor engages with the working beam rack. With the above structure, the movement of the working beam relative to the crossbeam is automatically controlled by the motor acting on the rack, which is easy to operate.

[0027] The detection and identification instrument 4 is provided with an instrument rack, and the working beam 8 is provided with a working beam motor. The working beam drive gear of the working beam motor meshes with the instrument rack. With the above structure, the movement of the working beam crossbeam of the detection and identification instrument 4 is automatically controlled by the motor acting on the rack.

[0028] When the flat surface 1 of the non-uniform thickness flexible glass is placed upward on the device workbench 3 for testing, the center 9 of the non-uniform thickness flexible glass and the edges 10 of the non-uniform thickness flexible glass extending in all directions from the center 9 are in the same plane. With the above structure, when the flat surface 1 of the non-uniform thickness flexible glass is placed upward on the device workbench 3 for testing, the entire top surface of the non-uniform thickness flexible glass is flat. The detection and identification instrument 4 uses the detection and identification probe 5 to measure the distances at different locations, obtain data, make a judgment, and then issue a judgment signal.

[0029] When the non-uniform thickness flexible glass is placed with its grooved surface 2 facing upward on the device workbench 3 for testing, the center 9 of the non-uniform thickness flexible glass forms a groove 11, and the level of the groove 11 is lower than the edge 10 of the non-uniform thickness flexible glass in all directions. With the above structure, when the non-uniform thickness flexible glass is placed with its grooved surface 2 facing upward on the device workbench 3 for testing, the entire top surface of the non-uniform thickness flexible glass is uneven. The detection and identification instrument 4 measures the distances at different locations using the detection and identification probe 5, obtains data, makes a judgment, and then issues a judgment signal.

[0030] The device's workbench 3 is provided with a vacuum suction hole 12, which connects to a central channel 13, which in turn is connected to a vacuum pump via a pipeline. This structure allows for vacuum suction of flexible glass of varying thicknesses after placement on the device's workbench, preventing movement. Upon completion of testing, the control unit automatically stops the vacuum pump, releasing the vacuum, and facilitates glass removal.

[0031] The detection and identification probe 5 is perpendicular to the device workbench 3. In the above structure, the detection and identification probe 5 is perpendicular to the device workbench 3, and the detection and identification probe 5 is perpendicular to the non-uniform thickness flexible glass 14 during detection, thereby obtaining accurate distance data for correct identification.

[0032] The non-equal-thickness flexible glass surface detection device, aiming at the characteristics of the non-equal-thickness flexible glass 14 including a flat surface 1 and a grooved surface 2, the device workbench 3 is used for placing the non-equal-thickness flexible glass 14 to be detected, the detection and identification instrument 4 is arranged above the device workbench 3, the detection and identification instrument 4 includes the detection and identification probe 5, the detection and identification probe 5 can detect the distance data between the probe end and the non-equal-thickness flexible glass 14, and whether the non-equal-thickness flexible glass 14 is the flat surface 1 upward or the grooved surface 2 upward is judged according to the distance. When it is needed to judge the grooved surface 2 of the non-equal-thickness flexible glass 14, the non-equal-thickness flexible glass 14 is placed on the device workbench, when the non-equal-thickness flexible glass 14 is placed on the device workbench 3 with the flat surface 1 upward for detection, the center position 9 of the non-equal-thickness flexible glass and the edge position 10 of the non-equal-thickness flexible glass extending in each direction of the center position 9 are in the same plane, at this time, the detection and identification instrument 4 displays the signal that the non-equal-thickness flexible glass 14 is the flat surface upward. When the grooved surface 2 of the non-equal-thickness flexible glass 14 is placed on the device workbench 3 with the grooved surface 2 upward for detection, the center position 9 of the non-equal-thickness flexible glass 14 is the groove part 11, and the horizontal height of the groove part 11 is lower than the edge position 10 of the non-equal-thickness flexible glass 14 in each direction, at this time, the detection and identification instrument 4 displays the signal that the non-equal-thickness flexible glass 14 is the grooved surface 2 upward. In this way, whether the non-equal-thickness flexible glass 14 is the flat surface 1 upward or the grooved surface 2 upward, only one detection is needed, and the identification can be realized, and then the operator takes away the non-equal-thickness flexible glass 14 and performs bonding. In this way, the flat surface and the grooved surface of the non-equal-thickness flexible glass are effectively identified, the identification error rate of personnel for the front and back surfaces of the non-equal-thickness flexible glass is reduced, the whole device structure is simple, and the personnel operation is convenient.
