Description

Technical Field

[0001] The utility model relates to the field of glass coating, in particular to a device for monitoring water accumulation in an inner groove of a coating cathode terminal of a glass coating system. Background Art

[0002] In the glass coating system, coating equipment is often used for coating. The coating equipment generally adopts Adenauer coating equipment. When the equipment is used for coating, the working environment of the equipment is generally a high temperature environment. For example, a glass coating and drying integrated device with patent application number 201821409278.4 is used. By arranging a UV lamp group and a blower group in the drying room, the UV lamp group makes the heat in the drying room evenly distributed, thereby improving the glass drying quality, but introducing a new heat source.

[0003] It can be seen that the coating equipment has a high-temperature working environment, especially the medium-frequency power supply unit that provides power for the equipment. In the prior art, the Adenauer coating method is often used. The Adenauer coating line of this method is the connecting line of the medium-frequency power supply. It uses a plug-in connector to connect the power line to the electrical appliances. However, due to the high temperature working environment, there is a water cooling system in the coating scheme of the prior art. The existence of the water cooling system will inevitably cause water accumulation in the inner groove corresponding to the end of the power connection line. If the Adenauer coating scheme is adopted, the inner groove of the imprint end of the Adenauer coating line may accumulate in the inner groove due to condensation or leakage of the cooling water pipe, causing the end to burn out and the cathode jump target accident. Therefore, it is necessary to monitor the water accumulation in the inner groove of the cathode end of the coating, and timely discover the water accumulation phenomenon, which is of great significance for timely treatment. There is no relevant technology disclosed in the prior art in terms of monitoring the water accumulation in the inner groove of the cathode end of the coating. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a device for monitoring water accumulation in the inner groove of the coated cathode end head of a glass coating system, comprising a water detection sensor, a microprocessor, and an audible and visual alarm. A water detection sensor is arranged in the inner groove of the coated cathode end head, and the output end of the water detection sensor is connected to the microprocessor for sending the detected water accumulation data in the inner groove of the coated cathode end head to the microprocessor; the output end of the microprocessor is connected to the audible and visual alarm, and the microprocessor controls the operation of the audible and visual alarm according to the water accumulation data.

[0006] The sound and light alarm is arranged in the coating central control room.

[0007] The microprocessor is connected to an Internet of Things module, and the Internet of Things module is connected to a terminal device of a monitoring person via a network. The microprocessor establishes a connection with the terminal device based on the Internet of Things module, and is used to send a monitoring alarm signal to the terminal device.

[0008] The output end of the microprocessor is connected to a contactor, and the contactor is connected in series to a power supply circuit of a glass coating system device.

[0009] The microprocessor is connected to the timer and is used to control the opening and closing of the contactor after the delay time is reached.

[0010] The microprocessor is connected to the liquid cooling device of the glass coating system and is used to send a stop signal to the liquid cooling device according to the water accumulation data.

[0011] The advantages of the utility model are: it can realize automatic monitoring of water accumulation in the inner groove of the coated cathode end head, and give a reminder, which is convenient for monitoring and processing; the water accumulation alarm can send an alarm reminder signal through the central control room and the mobile phone, realizing the reliable transmission of the alarm notification information; the system is connected to the coating equipment and the cooling device, and controls the coating equipment and the cooling device to suspend operation after detecting water accumulation, so as to avoid equipment failure caused by continuous operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following is a brief description of the contents expressed in the drawings of the present invention and the symbols in the drawings:

[0013] Figure 1 This is the electrical control logic diagram of the device of the utility model. DETAILED DESCRIPTION

[0014] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0015] In the field of glass coating, the commonly used solution is that the cathode end of the Adenauer coating line and the inner groove corresponding to the end are plug-in. Although the plug-in is a convenient connection, it inevitably produces a little gap. In the field of coating, due to the working environment, the equipment is equipped with a liquid cooling system / device. The cooling device generally arranges some liquid pipes on the equipment or power supply of the coating system to take away the heat. Water is commonly used in the liquid pipe, but due to the sealing of the pipe, the interface, and the interaction between hot and cold, water drops fall into the inner groove of the interface, which will cause problems in the electrical connection of the plug-in, and even seriously damage the normal operation of the equipment. In the coating system, the more important thing is the inner groove corresponding to the cathode end of the Adenauer coating line. The connection between the plug and the inner groove here is actually to establish the power supply of the medium-frequency power supply unit, so if water enters here, it will cause production safety hazards. Similarly, in addition to this, how other plug-ins enter water and accumulate water will also affect the safe operation of the system equipment. Therefore, this solution is to introduce a water detection sensor to detect water accumulation. After detecting the water accumulation signal, an alarm reminder signal is issued in time to avoid equipment operation failure accidents caused by water accumulation.

[0016] like Figure 1 As shown, a device for monitoring water accumulation in the inner tank of the cathode end of a glass coating system includes a water detection sensor, a microprocessor, and an audible and visual alarm;

[0017] The water detection sensor mainly detects the accumulated water in the inner groove for plugging. The water sensor can be realized by a resistive or capacitive water immersion sensor. The detection of the accumulated water signal in the inner groove can be completed by setting a water detection sensor in the inner groove of the coated cathode terminal.

[0018] The output end of the water detection sensor is connected to the microprocessor, which is used to send the detected water accumulation data in the inner groove of the coated cathode terminal to the microprocessor; the microprocessor uses the STM32 series single-chip microcomputer, and different models can be selected according to actual needs. The STM32 single-chip microcomputer has the advantages of low cost, rich resources, and simple development. It can be quickly installed and arranged as the core controller. After the microprocessor receives the water accumulation signal, it determines whether an alarm signal needs to be issued based on the water accumulation signal.

[0019] The output end of the microprocessor is connected to the sound and light alarm, and the microprocessor controls the operation of the sound and light alarm according to the water accumulation data. After receiving the water accumulation signal, the microprocessor determines whether it is necessary to issue an alarm signal according to the water accumulation signal. When it is determined that it is not necessary to issue an alarm reminder signal, it does not act; when it is determined that it is necessary to issue an alarm signal according to the received water accumulation signal, it outputs an alarm signal to the sound and light alarm, drives the sound and light alarm to issue a water accumulation alarm signal, and promptly reminds the staff to find the water accumulation and deal with it in time. Timely handling of the water accumulation in the inner tank will reduce or even avoid the occurrence of short circuits caused by water accumulation, and avoid damage to the operation of the equipment.

[0020] In a preferred embodiment, in order to better provide monitoring alarms, the sound and light alarm is set in the coating control room and the monitoring room. Since production enterprises are equipped with monitoring rooms, it is convenient for enterprise monitoring personnel to monitor the alarm signal and timely discover and deal with it. Since there is a certain distance between the control room and the site, a signal transfer system needs to be set between the microprocessor and the sound and light alarm. The control signal of the microprocessor can be sent to the sound and light alarm by wire or wireless method to achieve the purpose of stable alarm drive control.

[0021] In another preferred embodiment of the present application, in order to quickly and accurately notify the inspection personnel or monitoring personnel in real time, and to promptly notify each associated person of the alarm information, this embodiment sends the alarm signal to the mobile phone of each monitoring personnel through the Internet of Things technology, so as to timely discover and accurately send the alarm. Its scheme is set as follows: the microprocessor is connected to the Internet of Things module, the Internet of Things module is connected to the terminal device of the monitoring personnel via the network, and the microprocessor establishes a connection with the terminal device based on the Internet of Things module, which is used to send a monitoring alarm signal to the terminal device. Among them, the Internet of Things module is an Internet of Things chip with any of the 2G-5G network communication methods, which has the ability to forward the alarm signal of the microprocessor through the network. The terminal device is generally implemented by the associated personnel, such as the mobile phone of the inspection personnel. It only needs to bind the Internet of Things module to the mobile phone number of the associated personnel, or develop the corresponding app, and then the alarm signal can be transmitted to each associated personnel through the Internet of Things module, so as to avoid the occurrence of water accumulation failures caused by the failure of the associated maintenance personnel to find it in time.

[0022] In a preferred embodiment, after water accumulation is detected, short circuits may occur, burning out equipment, etc. Therefore, after water accumulation is detected, an alarm signal should be issued in a timely manner, and the operation of related equipment should be disconnected in a timely manner to avoid the escalation of the situation. Specifically, two methods can be used:

[0023] 1. Disconnect the equipment related to the glass coating system, connect the output end of the microprocessor to the contactor, and connect the contactor in series to the power supply circuit of the glass coating system equipment. The contactor adopts an AC contactor, which mainly serves the purpose of power on and off. When the water accumulation is detected, an alarm signal can be sent out, and a control signal can be sent to the contactor through the microprocessor to control the contactor to disconnect. Since the disconnection of the contactor causes the power supply circuit to be disconnected, the equipment cannot be powered on, thereby realizing the timely shutdown of the equipment and avoiding the safety hazard of short circuit and burning of the equipment caused by water accumulation. Furthermore, because the alarm is to allow users to deal with and remove the water accumulation in time, a certain delay time is set. When there is still water accumulation after the delay time reaches a certain time, the contactor is directly disconnected at this time, which can give the maintenance personnel a certain maintenance time to avoid the equipment from working in a risky state due to missed maintenance. At this time, a delayer can be added to the microprocessor IDE development class. The microprocessor is connected to the delayer to control the disconnection and closing of the contactor after the delay time is reached. The control after the delayer is delayed is more reasonable to meet the process of industrial maintenance processing.

[0024] 2. Shut down the liquid cooling system in time after the alarm is issued. The microprocessor is connected to the liquid cooling device of the glass coating system and is used to send a stop signal to the liquid cooling device according to the water accumulation data. The liquid cooling device is the cause of the water accumulation. Therefore, after the water accumulation alarm is issued, shutting down the liquid cooling system in time can further reduce the increase of water accumulation and avoid further deterioration of safety risks caused by the increase of water accumulation.

[0025] In this scheme, since there is no detection device for water accumulation in the inner tank of the cathode terminal, when there is water leakage around the terminal and flows into the inner tank, a short circuit fault of the terminal will occur, causing the terminal to burn out and the cathode to jump the target. Therefore, in the scheme of this application: by installing a water detection sensor in the bottom tank of the cathode terminal, and then connecting the signal of the water detection sensor to the matching sound and light alarm, the received signal is transmitted to the coating control room, and a sound and light alarm is installed in the coating control room to remind the operator of the control room. When the water detection sensor detects that there is water accumulation in the inner tank of the cathode terminal, the signal is transmitted to the coating control room in time to generate a sound and light alarm. After receiving the alarm signal, the operator of the control room takes timely response measures to avoid causing subsequent equipment failures and causing equipment and production losses. A water level detection sensor is installed in the inner tank of the terminal, and the detection signal is transmitted to the sound and light alarm in the coating control room. When there is water in the inner tank, the sound and light alarm will issue an alarm to remind the operator of the control room to deal with it in time.

[0026] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
