Description

Technical Field

[0001] This application belongs to the field of carrier glass production, and particularly relates to a thickness detection device for carrier glass. Background Art

[0002] Carrier glass is mainly used as the substrate of display screens. After going through multiple processes such as melting, forming and cooling, cutting, and grinding, various inspections are finally carried out on the carrier glass to complete the production of the carrier glass.

[0003] During the parameter detection process of carrier glass, the detection of thickness is one of the most important parameters. Traditional thickness detection of carrier glass is mostly manual sampling inspection. That is, after production is completed or during the production process, after sampling the carrier glass, it is measured by tools such as micrometers. This method not only has low efficiency, but also because it cannot be detected online, a large number of unqualified products will flow into the market, affecting the product's reputation.

[0004] Therefore, there is an urgent need for a thickness detection device for carrier glass that can solve the above problems. Utility Model Content

[0005] In order to solve the deficiencies of the existing technology, this application provides a thickness detection device for carrier glass, which can detect the thickness of the carrier glass online to achieve full inspection of the products.

[0006] The technical effects to be achieved by this application are realized through the following solutions:

[0007] According to the first aspect of this application, there is provided a thickness detection device for carrier glass, including a support frame, a measuring arm, a pressing wheel, and a distance detector. The support frame is fixed to the side of the conveying roller path, the measuring arm is rotatably connected to the support frame, the pressing wheel is installed at the bottom of the end of the measuring arm extending into the conveying roller path, and is pressed against the conveying roller path under the action of a pressing spring. A measuring table is arranged below the other end of the measuring arm, and the distance detector is fixed to the measuring table and detects the distance from the measuring arm.

[0008] With this solution, when the carrier glass passes through the conveying roller path online, the pressing wheel can be pressed against the top of the carrier glass, causing the height of the other end of the measuring arm to change. By detecting this height difference with the distance detector, the thickness of the current carrier glass can be known. It is not only convenient to measure but also has high efficiency, and can realize online detection of the carrier glass.

[0009] Preferably, the length of the measuring arm extending out of the conveying roller path is greater than the other end of the measuring arm.

[0010] With this solution, the moving distance of the outer measuring arm can be amplified during measurement, so that even more subtle thickness changes can be detected, improving the measurement accuracy.

[0011] Preferably, a guide plate is provided in front of the pressing wheel. The guide plate is fixed to the measuring arm and is inclined so that its extension line is at the bottom end of the pressing wheel.

[0012] With this solution, the guide plate can lift the measuring arm as the carrier glass is squeezed, preventing the pressing wheel from directly hitting the end of the carrier glass and causing damage, or hitting it and affecting the service life of the pressing wheel.

[0013] Preferably, a measuring plate is provided above the distance detector, and the measuring plate is in a downward arc shape.

[0014] With this solution, the arc-shaped measuring plate can reflect the laser emitted by the distance detector, preventing the inclined measuring arm from being unable to effectively reflect the laser.

[0015] Preferably, the support frame extends towards the side of the pressing wheel to form a pressing arm, and the pressing spring is installed between the pressing arm and the measuring arm.

[0016] With this solution, the pressing arm can press the end of the measuring arm close to it, increasing the force arm, thereby increasing the pressing force and preventing the pressing arm from bouncing due to vibration and affecting the measurement accuracy.

[0017] Preferably, one end of the measuring table is fixed to the side wall of the conveying roller path and is fixed to the top of the side wall of the conveying roller path by an inclined tie rod.

[0018] With this solution, the stability of the measuring table is improved, thereby improving the measurement accuracy.

[0019] According to an embodiment of the present application, the beneficial effect of using the thickness detection device for the carrier glass is that it can detect the thickness of the carrier glass in-line, thereby achieving full detection, greatly improving the qualification rate; moreover, this device has high detection efficiency and high detection accuracy.

[0024] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] As Figures 1 to 3 As shown, the thickness detection device for the carrier glass in an embodiment of the present application includes a support frame 110, a measuring arm 120, a pressing wheel 130, and a distance detector 140. The support frame 110 is fixed to the side of the conveying roller path 200. The measuring arm 120 is rotatably connected to the support frame 110. The pressing wheel 130 is installed at the bottom of one end of the measuring arm 120 extending into the conveying roller path 200 and is pressed against the conveying roller path 200 under the action of a pressing spring 121. A measuring table 150 is arranged below the other end of the measuring arm 120. The distance detector 140 is fixed to the measuring table 150 and detects the distance from the measuring arm 120.

[0026] Through the solution of this embodiment, when the carrier glass passes through the conveying roller path 200 along the line, the pressing wheel 130 can be pressed against the top of the carrier glass, causing the height of the other end of the measuring arm 120 to change. By detecting this height difference with the distance detector 140, the thickness of the current carrier glass can be known. It is not only convenient to measure but also has high efficiency, and can realize the on-line detection of the carrier glass.

[0027] The measuring arm 120 and the support frame 110 in this embodiment are supported by an aluminum alloy material, which not only has high strength but also has a small weight, avoiding excessive pressure on the conveying roller path 200 during long-term use.

[0028] The elastic force of the pressing spring 121 is greater than the weight of the measuring arm 120, and can press the pressing wheel 130 against the passing carrier glass.

[0029] The distance detector 140 is, for example, a laser distance detector 140, which has the characteristics of high detection efficiency and high detection accuracy; it can also be an ultrasonic rangefinder, etc. By detecting the distance that the measuring arm 120 descends in real time, the thickness of the current carrier glass can be known.

[0030] In an embodiment of the present application, the length of the measuring arm 120 extending out of the transfer roller path 200 is greater than the other end of the measuring arm 120. When measuring, the moving distance of the outer measuring arm 120 can be amplified, so that more subtle thickness changes can be detected, thereby improving the measurement accuracy.

[0031] In an embodiment of the present application, a guide plate 131 is provided in front of the pressing wheel 130. The guide plate 131 is fixed to the measuring arm 120, and the guide plate 131 is inclined so that its extension line is at the bottom end of the pressing wheel 130. The guide plate 131 can lift the measuring arm 120 as the carrier glass is squeezed, avoiding direct impact of the pressing wheel 130 on the end of the carrier glass and causing damage, or impact affecting the service life of the pressing wheel 130.

[0032] The guide plate 131 is made of nylon material, which not only has high stiffness to lift the measuring arm 120, but also has a self-lubricating effect, reducing the damage of friction force to the carrier glass.

[0033] The rolling direction of the pressing wheel 130 is the same as the moving direction of the carrier glass. The pressing wheel 130 is made of nylon material and has high strength, so that the thickness detection accuracy will not be affected by extrusion deformation, and the nylon material will not scratch the carrier glass.

[0034] In an embodiment of the present application, a measuring plate 122 is provided above the distance detector 140. The measuring plate 122 is an arc shape facing downwards. The arc-shaped measuring plate 122 can reflect the laser emitted by the distance detector 140, avoiding the inability of the inclined measuring arm 120 to effectively reflect the laser.

[0035] In an embodiment of the present application, the support frame 110 extends towards the side of the pressing wheel 130 to form a pressing arm 111. The pressing spring 121 is installed between the pressing arm 111 and the measuring arm 120. The pressing arm 111 can press the end of the measuring arm 120 close to it, increasing the force arm, thereby increasing the pressing force, and avoiding the jumping of the pressing arm 111 caused by vibration and affecting the measurement accuracy.

[0036] In an embodiment of the present application, one end of the measuring table 150 is fixed to the side wall of the transfer roller path 200 and is fixed to the top of the side wall of the transfer roller path 200 through an inclined tie rod. The stability of the measuring table 150 is improved, thereby improving the measurement accuracy.

[0037] According to this embodiment, the beneficial effect of adopting the thickness detection device for the carrier glass is that the thickness of the carrier glass can be detected along the line, so as to achieve all detections, greatly improving the qualification rate; and this device has high detection efficiency and high detection accuracy.
