[0032] In related technologies, drilling is required during the glass manufacturing process. Before drilling, a drilling fluid, such as diethylene glycol, is typically applied to the glass surface.

[0033] Specifically, the drilling fluid is stored in a storage tank 200, which is connected to a coating mechanism. A pump can deliver the drilling fluid from the storage tank 200 to the coating mechanism, which then coats the glass with the drilling fluid. Furthermore, when the amount of drilling fluid in the storage tank 200 is insufficient, the coating mechanism will malfunction. Therefore, this application proposes a quantitative infusion device 100.

[0034] Please refer to Figure 1In some embodiments, the quantitative infusion device 100 includes: a storage tank 200, a metering tank 300, a coating mechanism, and a level sensor. The storage tank 200 stores the perforating fluid. The storage tank 200 has a relatively large volume and its shape can be cylindrical or cuboid, etc. The height of the metering tank 300 is less than the height of the storage tank 200, and the top of the metering tank 300 is connected to the bottom of the storage tank 200. That is, when the perforating fluid in the storage tank 200 is full, the perforating fluid in the metering tank 300 is also full; when the perforating fluid in the storage tank 200 is lower than the height of the metering tank 300, the liquid level of the perforating fluid in the storage tank 200 and the liquid level of the perforating fluid in the metering tank 300 are the same, thereby allowing detection of whether the perforating fluid in the storage tank 200 is insufficient. The top of the metering tank 300 is connected to the bottom of the storage tank 200 via a pipeline. The coating mechanism is connected to the metering tank 300, which can be connected via pipeline. The coating mechanism is used to coat the glass with liquid. This coating mechanism is existing technology and will not be described further here. A level sensor is connected to the metering tank 300 and is used to monitor the liquid level within the metering tank 300. Specifically, the height of the metering tank 300 is less than the height of the storage tank 200, and the top of the metering tank 300 is connected to the bottom of the storage tank 200. Thus, the perforated fluid in the storage tank 200 flows into the metering tank 300. A level sensor is connected to the metering tank 300 and is used to detect the liquid level within the metering tank 300. Specifically, when the volume of perforated fluid in the storage tank 200 is low, the volume of perforated fluid in the metering tank 300 is also low, and the liquid level in the storage tank 200 can be the same as the liquid level in the metering tank 300. By detecting the liquid level in the metering tank 300, the level sensor determines the remaining amount of perforated fluid in the storage tank 200, allowing for timely replenishment of the storage tank 200. In essence, the metering infusion device 100 can monitor the remaining amount of perforated fluid in the storage tank 200, thereby enabling timely replenishment.

[0035] The following describes liquid level sensors. Liquid level sensors can be submersible type, where the probe of the submersible sensor is placed inside the metering tank 300 to measure the hydrostatic pressure of the liquid, converting the pressure signal into a standard electrical signal output to calculate the liquid level height. Alternatively, liquid level sensors can be capacitive type, utilizing a capacitive circuit formed by the sensor probe, liquid, and tank wall. The capacitance changes synchronously with the liquid level (the higher the liquid level, the greater the capacitance), and the circuit converts the capacitive signal into a liquid level signal. Liquid level sensors can also be radar type, transmitting high-frequency radar waves towards the liquid surface via an antenna. The radar waves are reflected upon encountering the liquid surface, and the sensor measures the time difference between transmission and reception, combining this with the wave velocity to calculate the liquid level height.

[0036] Furthermore, as mentioned above, the liquid level sensor can detect the volume of the perforated liquid in the metering tank 300. However, in some cases, the liquid level sensor may malfunction or operate incorrectly, leading to deviations in the liquid level monitoring of the metering tank 300. Therefore, in some embodiments, the metering infusion device 100 also includes a scale 400 connected to the metering tank 300. Specifically, the scale 400 can detect the remaining amount of perforated liquid in the metering tank 300. The scale 400 is a mechanical device, effectively avoiding problems caused by electronic circuit failures. That is, by setting up the scale 400, the accuracy of detecting the volume of perforated liquid in the storage tank 200 and the metering tank 300 can be further improved.

[0037] Further, please refer to Figure 1 In some embodiments, the coating mechanism includes a metering valve 500 and a coating machine. The two ends of the metering valve 500 are connected to a metering tank 300 and the coating machine, respectively. Specifically, the metering valve 500 can be an electromagnetic metering valve 500, an electric screw metering valve 500, or a pneumatic diaphragm metering valve 500. The metering valve 500 can meterly deliver the drilling liquid to the coating machine, allowing the coating machine to spray the drilling liquid onto the glass. The metering valve 500 enables precise metering of the drilling liquid onto the glass, thereby improving the processing quality of the glass. Furthermore, the metering valve 500 can provide an alarm for glass coating leakage; that is, when glass coating leakage occurs, the metered amount of drilling liquid in the metering valve 500 will be abnormal. Specifically, the metering valve 500 facilitates the identification of whether the glass has been coated. The coating machine includes a spray nozzle and a cylinder; the cylinder delivers the drilling liquid to a nozzle, which sprays the drilling liquid onto the glass.

[0038] Further, please refer to Figure 1 In some embodiments, multiple metering valves 500 and coating machines are provided. Exemplarily, there may be two, three, four, five, or ten metering valves 500 and coating machines. Each metering valve 500 is connected to one coating machine, and all metering valves 500 are connected to the same metering tank 300. Specifically, the arrangement of multiple metering valves 500 and coating machines allows one metering tank 300 to supply liquid to multiple spraying lines. That is, the arrangement of multiple coating mechanisms allows multiple pieces of glass to be coated simultaneously, which can greatly improve processing efficiency.

[0039] Further, in some embodiments, the distance between the storage tank 200 and the metering tank 300 is L1, and the distance between the metering tank 300 and the coating mechanism is L2, where L1 > L2. Specifically, the distance between the storage tank 200 and the metering tank 300 can be ten meters, twelve meters, thirteen meters, fifteen meters, or twenty meters, etc. The distance between the metering tank 300 and the coating mechanism can be within two meters or within one meter. The storage tank 200 has a larger volume, allowing it to hold a large amount of drilling fluid. The larger volume of the storage tank 200 allows it to be placed in a more spacious environment. Because the storage tank 200 is far from the coating mechanism, it is inconvenient to observe the remaining amount of drilling fluid in the storage tank 200. To facilitate observation of the remaining amount of drilling fluid, it can be observed by observing the drilling fluid in the metering tank 300, which is located nearby.

[0040] Furthermore, in some embodiments, multiple metering tanks 300 are provided. Each of the multiple metering tanks 300 is connected to the storage tank 200. There may be two, three, four, five, six, or ten metering tanks 300, etc. One storage tank 200 supplies liquid to multiple metering tanks 300. Specifically, one storage tank 200 can supply liquid to multiple metering tanks 300, and one metering tank 300 can supply liquid to multiple coating mechanisms in a metered manner. Thus, the above arrangement allows for the simultaneous coating of many pieces of glass, thereby improving glass processing efficiency.

[0041] Furthermore, in some embodiments, the quantitative infusion device 100 also includes a first photoelectric sensor. The first photoelectric sensor is used to detect the position of the glass. Specifically, the glass is conveyed by a conveyor belt between the coating mechanism and the glass being coated. After the conveyor belt transports the glass to a designated position, the glass is then coated. The first photoelectric sensor can be located beside the conveyor belt, and it can detect whether the glass is in position using a light signal. That is, after the first photoelectric sensor detects the position of the glass, the controller can control the conveyor belt to stop conveying the glass. When the glass stops, it is in position, and at this time, it can be coated by the coating mechanism. The controller is a feedback loop component widely used in industrial control applications, such as a programmable memory. It internally stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs. The principle and control method of the controller are prior art and will not be described in detail here.

[0042] Furthermore, when the glass is conveyed on the conveyor belt, even if the conveyor belt stops immediately, the glass may continue to move due to inertia, which could lead to glass damage or prevent the glass from stopping at the designated position. Therefore, in some embodiments, the quantitative infusion device 100 also includes a second photoelectric sensor. Along the glass conveying direction, the second photoelectric sensor is located in front of the first photoelectric sensor, and the second photoelectric sensor is used to detect the position of the glass. Specifically, the second photoelectric sensor is located in front of the first photoelectric sensor, so the second photoelectric sensor can detect the position of the glass first. When the conveyor belt conveys the glass, after the second photoelectric sensor detects the glass, the controller receives a signal and can control the conveyor belt to slow down. Then, the first photoelectric sensor can detect the glass again, and the controller can then control the conveyor belt to stop conveying. That is, the setting of the second photoelectric sensor can achieve the deceleration of the glass, and the setting of the first photoelectric sensor can achieve the stopping of the glass conveying.

[0043] Furthermore, in some embodiments, the quantitative infusion device 100 also includes a supply component. The supply component is connected to the storage tank 200 and is used to replenish the storage tank 200. Specifically, the supply component may include a supply pump, which can replenish the perforation fluid to the storage tank 200. The operation of the quantitative infusion device is as follows: When the glass moves along the conveyor line and passes the second photoelectric sensor, the controller can control the speed of the conveyor line to decelerate the glass. The glass continues to be conveyed, and when it passes the first photoelectric sensor, the controller can stop the conveyor belt. Then, the controller controls the quantitative valve 500 to quantitatively spray the perforation fluid onto the glass. In addition, when the perforation fluid in the quantitative tank 300 is insufficient, the level sensor can send a signal to the controller, which then controls the supply component to replenish the storage tank 200.

[0044] In some embodiments, the production line includes a metering device according to any of the above embodiments. Specifically, the height of the metering tank 300 is less than the height of the storage tank 200, and the top of the metering tank 300 is connected to the bottom of the storage tank 200. Thus, the perforating fluid in the storage tank 200 flows into the metering tank 300. A level sensor is connected to the metering tank 300 and is used to detect the liquid level in the metering tank 300. Specifically, when the volume of perforating fluid in the storage tank 200 is low, the volume of perforating fluid in the metering tank 300 is also low, and the liquid level in the storage tank 200 can be the same as the liquid level in the metering tank 300. By detecting the liquid level in the metering tank 300, the level sensor can determine the remaining amount of perforating fluid in the storage tank 200, allowing for timely replenishment of the storage tank 200. Specifically, the metering delivery device 100 can monitor the remaining amount of perforating fluid in the storage tank 200, thereby enabling timely replenishment. Furthermore, the production line equipped with the quantitative infusion device 100 has good production continuity.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
