Description

Technical Field

[0001] The utility model relates to the technical field of panel manufacturing, and in particular to a dual glass substrate sensing and detection device. Background Art

[0002] Glass substrate sensing and detection devices (swing-type sensors) are used by panel manufacturers to monitor the glass substrate's position within the conveyor mechanism during production. Sensor failures can cause machine downtime, resulting in product scrap and rework. Utility Model Content

[0003] The purpose of the utility model is to provide a dual glass substrate sensing and detection device, which can not only improve the reliability of glass substrate sensing and detection, but also has a simple structure, is easy to implement, and has good use effect.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a dual glass substrate sensing and detection device, including two sets of sensing and detection devices and a control unit, the two sets of sensing and detection devices are installed on the conveying mechanism of the glass substrate production line, so as to sense whether the glass substrate passes through respectively through the two sets of sensing and detection devices, and the sensor signal lines of the two sets of sensing and detection devices are electrically connected to the control unit at the same time.

[0005] Furthermore, the two groups of sensing and detecting devices are horizontally installed side by side on the conveying mechanism, and the side-by-side installation direction is perpendicular to the conveying direction of the glass substrate, so as to simultaneously sense whether the glass substrate passes through.

[0006] Furthermore, the sensing detection device is a swinging detection sensor, which consists of a magnetic vibrator base and a sensor signal line. The magnetic vibrator base is installed vertically, and has a swingable magnetic vibrator on the magnetic vibrator base. When the magnetic vibrator is in a vertical state, it indicates that there is no substrate or the substrate has passed. When the magnetic vibrator is deflected by the substrate, it indicates that the substrate is present. The magnetic vibrator base is electrically connected to the control unit through the sensor signal line to transmit the presence status of the glass substrate to the control unit.

[0007] Furthermore, the conveying mechanism is respectively provided with two lifting mechanisms that work independently of each other, and the two groups of sensing and detection devices are respectively installed on the two lifting mechanisms. The control unit is respectively electrically connected to the two lifting mechanisms to respectively control the operation of the two lifting mechanisms, thereby driving the corresponding sensing and detection devices to rise and fall.

[0008] Furthermore, the control unit is connected to an alarm module.

[0009] Compared with existing technologies, the present invention has the following advantages: It provides a dual-sensing and detecting device for glass substrates. This device achieves dual detection of glass substrates by providing two sets of sensing and detecting devices. When one set of sensors malfunctions, the other set of sensors can still perform normal detection. This improves the reliability of glass substrate sensing and detection, ensuring that glass substrate production can proceed smoothly without being affected and preventing product scrapping and rework due to sensor anomalies. Sensor replacement is only required during subsequent maintenance downtime. Furthermore, the device has a simple structure, is easy to implement, and is inexpensive to implement. Therefore, the present invention has strong practicality and broad application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0017] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] like Figure 1-3As shown, this embodiment provides a dual-layer glass substrate sensing and detection device, comprising two sets of sensing and detection devices K1 and K2, and a control unit U1. Both sets of sensing and detection devices K1 and K2 are mounted on the conveyor mechanism of a glass substrate production line to sense whether a glass substrate G1 has passed through the conveyor. Sensor signal lines S1 and S2 of the two sets of sensing and detection devices are electrically connected to the control unit U1. An alarm module A1 is also connected to the control unit U1.

[0019] like Figure 2 、 3 As shown, the two sets of sensing and detecting devices K1 and K2 are horizontally installed side by side on the conveying mechanism, and the side-by-side installation direction is perpendicular to the conveying direction of the glass substrate G1, so as to simultaneously sense whether the glass substrate G1 passes through.

[0020] In this embodiment, the sensing detection devices K1 and K2 are both swing-type detection sensors. The two sets of swing-type detection sensors are composed of magnetic vibrator bases M1 and M2, respectively, and sensor signal lines S1 and S2. The magnetic vibrator bases M1 and M2 are mounted vertically and have swingable magnetic vibrators. When no glass substrate is passing, the magnetic vibrators remain vertical due to their own gravity. Induction with the sensor signal lines indicates the absence of a glass substrate (either the glass has barely arrived or has already passed). When a glass substrate passes, the magnetic vibrators are affected by the substrate and deflected. Induction with the sensor signal lines indicates the presence of a glass substrate. The magnetic vibrator bases M1 and M2 are electrically connected to the control unit U1 via sensor signal lines S1 and S2, respectively, to transmit the presence of a glass substrate to the control unit.

[0021] During the operation of the device, one of the sensing detection devices is in an abnormal state, such as Figure 4 Because this device implements dual detection, even if one sensor set fails, the machine can still operate normally. Control unit U1 issues an alarm through alarm module A1 and marks the failed sensor set. The marked sensor can then be replaced when the machine is shut down for maintenance.

[0022] When the sensing and detecting device is abnormal, in order to prevent the abnormal sensor from affecting the normal production and transportation of the glass substrate, in this embodiment, two independently working lifting mechanisms L1 and L2 are respectively provided on the conveying mechanism, and the two groups of sensing and detecting devices K1 and K2 are respectively installed on the two lifting mechanisms L1 and L2. The control unit U1 is electrically connected to the two lifting mechanisms L1 and L2 respectively to control the operation of the two lifting mechanisms L1 and L2 respectively, thereby driving the corresponding sensing and detecting devices to rise and fall.

[0023] Figure 5This is a schematic diagram of a glass substrate production line when a set of sensing and detection devices in this device is abnormal. Figure 5 As shown in the figure, when one of the sensing detection devices is abnormal, the machine will not shut down and the product will flow normally, effectively avoiding machine shutdown, product scrapping and rework caused by abnormal swing sensors, and improving machine work efficiency and product quality.

[0024] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention shall remain within the scope of protection of the present invention.
