Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of glass detection, and in particular to an ultra-thin glass edge stress detection device. Background Art
[0002] During the glass production process, after the glass is cooled and formed, it has both compressive stress to resist the compression tendency of the glass and tensile stress to resist the expansion tendency of the glass. The size and distribution of compressive stress and tensile stress determine the cutting method to be adopted in the next cutting process to ensure the quality of the glass after cutting.
[0003] For glass cutting, if the compressive stress or tensile stress on the edge of the glass is too high, it will affect the cutting. When cutting, corresponding cutting methods need to be adopted for these parts to avoid quality problems of the cut glass. When the compressive stress of the edge glass is too high, the force required to lift it from one side is relatively small, and this situation is called loose edge in production; when the tensile stress of the edge glass is too high, the force required to lift it from one side is relatively large, and this situation is called tight edge in production. When measuring whether the produced glass has loose or tight edges, the traditional technical means is that the production workers lift the glass plate by hand and judge according to their feelings: if the glass is very difficult to lift, it means that the edge is tight; if the glass is very easy to lift, it means that the edge is loose. This method of judging the stress magnitude at the edge of glass is practical and effective for glass with a certain thickness. However, for ultra-thin glass, especially glass with a thickness of less than 0.7 mm, the weight of the glass is too light, resulting in production workers being able to easily lift the glass regardless of the stress magnitude at the edge. At the same time, the influence of factors such as air resistance on the glass when it is lifted will be further amplified due to the reduction in the weight of the glass. At this time, the technical workers use subjective feelings to judge and distinguish the magnitude of the force used to lift each glass, and the result is greatly deviated from the actual situation, and cannot correctly reflect the stress magnitude, making it impossible to start the subsequent process of adjusting the glass stress.
[0004] Therefore, it is necessary to improve the method of judging the stress at the edge of ultra-thin glass, so as to ensure that the production and cutting process of ultra-thin glass can be carried out, and save the production cost of ultra-thin glass by reducing the waste generated during the cutting process. Utility Model Content
[0005] A technical problem to be solved by the present disclosure is: how to determine the stress magnitude at the edge of ultra-thin glass to guide the selection of the cutting position of the ultra-thin glass.
[0006] In order to solve the above technical problems, an embodiment of the present disclosure provides an ultra-thin glass stress detection device, including a support module and a pressure detection module. The support module includes a support vertical rod and a support cross rod that are vertically arranged to each other, one end of the support vertical rod is vertically arranged on the roller frame, and the support cross rod is connected to the support vertical rod. The pressure detection module is connected to one end of the support cross rod, and includes a contact wheel for supporting one side edge of the glass to be tested and a pressure sensing device connected thereto, and when the glass to be tested is conveyed to pass through the contact wheel, the pressure sensing device can sense the force generated by the glass to be tested.
[0007] In some embodiments, the support vertical rod extends in a vertical direction, and the pressure sensing device is arranged to be parallel to the support vertical rod.
[0008] In some embodiments, the contact wheel is connected to the pressure sensing device via a connecting rod, and the connecting rod extends in a horizontal direction so as to be parallel to the surface of the glass to be tested.
[0009] In some embodiments, the connecting rod can rotate around the pressure sensing device in a horizontal plane with the pressure sensing device as an axis.
[0010] In some embodiments, the contact wheel is rotatably connected to one end of the connecting rod.
[0011] In some embodiments, the outer periphery of the contact wheel is tangent to the moving plane of the glass to be tested on the roller, and the axial direction of the contact wheel is perpendicular to the moving direction of the glass to be tested on the roller.
[0012] In some embodiments, a vertical slot for connecting to the bracket cross bar is formed on the bracket vertical bar, and the bracket cross bar is detachably connected to the vertical slot through a first bolt and its height position can be adjusted.
[0013] In some embodiments, the support cross bar extends through the support vertical bar and is abutted and fixed by a first bolt connected to the support vertical bar, so that the position of the support cross bar can be adjusted in the lateral direction.

[0015] In some embodiments, the support crossbar extends in a horizontal direction and a rangefinder is disposed at the bottom.
[0016] Through the above technical scheme, the ultra-thin glass stress detection device provided by the present disclosure can reflect the stress size at the edge of the glass to be tested by the size of the force applied when the contact wheel lifts the glass to be tested to a specified height, and guide the subsequent glass cutting process according to the obtained data. Large compressive stress at the edge of the glass to be tested reflects the loose edge state, and large tensile stress reflects the tight edge state. In the loose edge state, a small force is applied to the edge of one side of the glass to be tested to lift it, while in the tight edge state, more force needs to be applied than in the loose edge state to lift the glass to be tested. The detection device provided by the present disclosure applies an upward force to the edge of the glass to be tested to lift it to a specific height through the contact wheel in contact with the glass to be tested, and obtains the force applied to the contact wheel from the glass to be tested through the pressure sensing device connected to the contact wheel. According to the size of the force, it can be distinguished whether the edges of the glass to be tested are tight or loose, thereby obtaining the size of the compressive stress and tensile stress at various locations of the glass to be tested, providing guidance for the subsequent cutting process of the glass to be tested. The detection device provided by the present disclosure can accurately distinguish the subtle differences in the force exerted by the edge of ultra-thin glass on the contact wheel, avoiding the errors caused by manual detection relying on subjective feelings, so that it can be applied to the detection link before ultra-thin glass cutting to provide guidance for cutting ultra-thin glass.

It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.
[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0028] In order to solve the above technical problems, the present invention provides an ultra-thin glass stress detection device, such as Figure 1 As shown, including:
[0029] The support module comprises a support vertical rod 5 and a support cross rod 4 which are vertically arranged to each other. One end of the support vertical rod 5 is vertically arranged on the roller frame 6 , and the support cross rod 4 is connected to the support vertical rod 5 .
[0030] The pressure detection module is connected to one end of the bracket cross bar 4, and includes a contact wheel 1 for supporting one side edge of the glass to be tested and a pressure sensing device 3 connected thereto. When the glass to be tested is conveyed past the contact wheel 1, the pressure sensing device 3 can sense the force generated by the glass to be tested.
[0031] The detection device provided by the present disclosure can reflect the stress size at the edge of the glass to be tested by the size of the force applied when the contact wheel 1 lifts the glass to be tested to a specified height, thereby guiding the subsequent cutting process. Large compressive stress at the edge of the glass to be tested reflects a loose edge state, and large tensile stress reflects a tight edge state. In the loose edge state, a small force is applied to one edge of the glass to be tested to lift it, while in the tight edge state, more force needs to be applied than in the loose edge state to lift the glass to be tested. The detection device provided by the present disclosure applies an upward force to the edge of the glass to be tested to lift it to a specific height through the contact wheel 1 in contact with the glass to be tested, and obtains the force applied to the contact wheel 1 from the glass to be tested through a pressure sensing device connected to the contact wheel 1. According to the size of the force, it can be distinguished whether the edges of the glass to be tested are tight or loose, thereby obtaining the size of the compressive stress and tensile stress at various locations of the glass to be tested, providing guidance for the subsequent cutting process of the glass to be tested. The detection device provided by the present disclosure can accurately distinguish the subtle differences in the forces generated by the edge of ultra-thin glass, avoiding the errors caused by manual detection relying on subjective feelings, so that it can be applied to the detection link before ultra-thin glass cutting to provide guidance for cutting ultra-thin glass.
[0032] The support module of the present invention is arranged on the roller frame 6 beside the roller, and the pressure detection module connected to the end of the support cross bar 4 can be hoisted above the roller through the mutually perpendicular support vertical rod 5 and support cross bar 4, and the contact wheel therein can be placed below the roller. When the roller starts to transport the ultra-thin glass to be tested, other components except the contact wheel 1 will not contact the glass to be tested on the roller, which increases the stability of the measurement result.
[0033] In some embodiments, Figure 1As shown, the support vertical rod 5 extends in the vertical direction, and the pressure sensing device 3 is arranged parallel to the support vertical rod 5. When the contact wheel 1 contacts the glass to be tested, the direction of the force applied to the glass to be tested is vertically downward, and the pressure sensing device 3 arranged parallel to the vertical support vertical rod 5 can more directly and accurately measure the force applied to the contact wheel 1, thereby obtaining more accurate compressive stress and tensile stress at various locations on the edge of the glass to be tested.
[0034] In some embodiments, Figure 1 As shown, the contact wheel 1 is connected to the pressure sensing device 3 through a connecting rod 2, and the connecting rod 2 extends in the horizontal direction so as to be parallel to the surface of the glass to be tested. Through the connecting rod 2, the contact wheel 1 can extend under the glass to be tested, so as to contact the bottom edge of the glass to be tested and perform measurement, and the connecting rod 2 along the horizontal direction can ensure that when the contact wheel 1 contacts the glass to be tested, the connecting rod 2 will not contact the glass to be tested, thereby ensuring the accuracy and safety of the measurement.
[0035] In some embodiments, the connecting rod 2 can rotate around the horizontal plane of the pressure sensing device 3 with the pressure sensing device 3 as the axis. Through the rotatable connecting rod 2, the contact position between the contact wheel 1 and the glass to be tested can be adjusted so that the force at the edge of the glass to be tested can be accurately detected, thereby ensuring that the obtained data can accurately describe the stress at the edge of the glass to be tested, providing more accurate guidance for subsequent glass cutting.
[0036] In some embodiments, the contact wheel 1 is rotatably connected to one end of the connecting rod 2. The rotatable contact wheel 1 allows the contact wheel 1 to rotate under the drive of the moving glass to be tested when it is in contact with the surface of the glass to be tested, thereby avoiding production safety issues such as friction and other resistance between the contact wheel 1 and the glass to be tested, which causes the moving glass to be tested to be subjected to resistance on only one side, resulting in unbalanced force and even tilting on the roller.
[0037] In some embodiments, the outer periphery of the contact wheel 1 is tangent to the moving plane of the glass to be tested on the roller, and the axial direction of the contact wheel 1 is perpendicular to the moving direction of the glass to be tested on the roller. When the glass to be tested is transmitted on the roller, the contact wheel 1, whose outer periphery is tangent to the moving glass to be tested and whose axial direction is perpendicular to the moving direction of the glass to be tested, can be completely driven by the movement of the glass to be tested, and rotates along with the movement of the glass to be tested while generating almost no resistance to the moving glass to be tested, so that the measuring device can perform measurements without affecting the operation of the glass production line.
[0038] In some embodiments, Figure 1As shown, the support cross bar 4 extends through the support vertical bar 5 and is fixed by abutting against the first bolt 51 connected to the support vertical bar 5, so that the position of the support cross bar 4 can be adjusted in the transverse direction. The first bolt 51 is arranged on the side of the support vertical bar 5, and when tightened, it can abut against the support cross bar 4 passing through the support vertical bar 5, thereby fixing the support cross bar 4 in a specific position. When it is necessary to adjust the position of the support cross bar 4, first loosen the first bolt 51, and when the support cross bar 4 can move freely, adjust its extended length to the required position, and then tighten the first bolt 51 to fix the position of the support cross bar 4. Through the support vertical bar 5, the support cross bar 4 and the first bolt 51 whose extended length can be adjusted, can adjust the extended length of the support cross bar 4 according to various factors such as the positional relationship between the detection device and the glass to be tested to meet the needs of different situations, so that the detection device can be applied to different glass production lines.
[0039] In some embodiments, a vertical groove for connecting the support cross bar 4 is formed on the support vertical rod 5, and the support cross bar 4 is detachably connected to the vertical groove by the first bolt 51 and can adjust its height position. The vertical groove is also provided with a groove that penetrates the vertical groove on the side where the first bolt 51 is provided, and its width is greater than the diameter of the screw rod of the first bolt 51 and less than the diameter of its nut. The first bolt 51 is provided in the groove and can automatically move up and down in the groove. When it is necessary to adjust the support cross bar 4, first loosen the first bolt 51, and after the support cross bar 4 can move up and down, adjust its height to the required position, and then adjust the first bolt 51 to the corresponding position and tighten it, so as to fix the support cross bar 4. Through the support vertical rod 5, the support cross bar 4 and the first bolt 51 whose height position can be adjusted can adjust the height position of the support cross bar 4 according to various factors such as the positional relationship between the detection device and the glass to be tested to meet the needs of different situations, so that the detection device can be applied to different glass production lines.
[0040] In some embodiments, a slot reserved for installing the bracket module is provided on the roller frame 6, and the bracket vertical rod 5 is detachably installed on the roller frame 6 by a second bolt 52. Through the bracket vertical rod 5 detachably installed on the roller frame 6, the detection device can also be disassembled or installed at any position of the roller frame 6 where the installation slot is reserved, so as to facilitate the production line to set the position of the detection device according to different situations to obtain the required data.
[0041] In some embodiments, Figure 1As shown, the support cross bar 4 extends in the horizontal direction and is provided with a distance meter 41 at the bottom. Through the distance meter 41, when setting the height position of the support cross bar 4 in the detection device, the distance between the support cross bar 4 and the ground can be measured, so that when multiple detection devices are set, the support cross bars 4 of multiple detection devices can be set at a uniform height, so that the contact wheels 1 of each detection device can be set at a uniform height, ensuring that the forces exerted on the glass to be tested by the multiple contact wheels 1 when contacting the glass to be tested are consistent, and there will be no situation where some contact wheels 1 are higher or lower than other contact wheels 1, resulting in inaccurate data obtained.

In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
