Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispensing controller technology, and in particular to a high-speed dispensing controller with a pressure stabilizing tank and digital displays for positive and negative pressure. Background Technology
[0002] Existing pneumatic dispensing controllers, when used to control dispensing or potting machines, are typically configured with a pressure-reducing valve to regulate air pressure, generally within a range of 0.05–0.7 MPa. The valve is locked at a roughly suitable pressure. Control of the air outlet and backflow mechanisms is usually achieved using a time relay in conjunction with digital dial indicators, and the result is displayed to the user via a digital display or pressure gauge. Because the regulating valve and pressure sensing components of these pneumatic controllers have relatively large unit resolutions, their unit adjustment accuracy is generally greater than 0.005 MPa. In dispensing processes where negative pressure is used to prevent leakage, this can easily lead to poor fluid return airflow. Furthermore, due to the instability of external air pressure, high-frequency switching processes can easily cause dispensing fluctuations, significantly impacting dispensing processes with high consistency requirements.
[0003] In addition, due to the limited number of control ports, the control ports that interact with the host computer generally use a single method of I / O switch signals, which will be limited by the number of ports in some high-frequency switching process scenarios.
[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a high-speed dispensing controller with a pressure stabilizing tank and positive and negative pressure digital display to solve the problems in the background art.
[0006] The technical solution of this utility model is as follows: A high-speed dispensing controller with a pressure stabilizing tank and digital displays for positive and negative pressure is provided, including: a main board, an external air source input port, a positive pressure regulating valve, a negative pressure regulating valve, a high-frequency multi-position solenoid valve, a negative pressure generator, an air storage tank, and an output port; the external air source input port is connected to the positive pressure regulating valve through a pipeline, the positive pressure regulating valve is connected to the air storage tank through a pipeline, and the negative pressure generator is connected to the negative pressure regulating valve through a pipeline; the high-frequency multi-position solenoid valve is connected to the negative pressure regulating valve, the air storage tank, and the output port through a pipeline; the main board is electrically connected to the control terminal of the high-frequency multi-position solenoid valve and the negative pressure generator respectively.
[0007] Gas enters the gas storage tank through an external gas source inlet and a positive pressure regulating valve, ensuring the stability of the tank's pressure and achieving the effect of a pressure stabilizing tank, which is clearly visible to the user. Its function is to ensure that dispensing is not affected by fluctuations in the external gas source, thus ensuring the consistency of the continuous dispensing process.
[0008] After being pressurized by the air tank, the air source connects to a high-frequency multi-position solenoid valve. This valve's function is to cut off the positive pressure supply or switch between positive and negative pressure during dispensing. The high-frequency multi-position solenoid valve is powered and signal-converted by the main board. The air outlet of the high-frequency multi-position solenoid valve faces the user and is used for final dispensing control. It can be connected to various quick-connect plugs and air hose plugs, allowing for user customization. The degassing end of the high-frequency multi-position solenoid valve connects to a negative pressure generator, and the air inlet of the negative pressure generator connects to a negative pressure regulating valve, also facing the user. When dispensing stops, the high-frequency multi-position solenoid valve switches to negative pressure suction. The negative pressure generated by the negative pressure generator draws back the glue at the dispensing nozzle, preventing residue. When the negative pressure is on, the air path at the high-frequency multi-position solenoid valve's outlet switches between positive and negative pressure; when off, only the positive pressure is switched.
[0009] Furthermore, the high-speed dispensing controller with a pressure stabilizing tank and digital displays for positive and negative pressure also includes: a first pressure sensor for detecting the pressure inside the air tank, a second pressure sensor for detecting the negative pressure generated by the negative pressure generator, and a display screen; the main board is electrically connected to the first pressure sensor, the second pressure sensor, and the display screen respectively. The second pressure sensor can monitor changes in negative pressure in real time, facilitating user adjustment. The display screen is used to display information such as the current dispensing mode, valve opening time, and negative pressure value.
[0010] Furthermore, the display screen is mounted on the motherboard. Both the first and second pressure sensors are digital pressure gauges.
[0011] Furthermore, the high-speed dispensing controller with a pressure stabilizing tank and positive and negative pressure digital displays also includes: a housing, on which the main board, external air source input port, positive pressure regulating valve, negative pressure regulating valve, high-frequency multi-position solenoid valve, negative pressure generator, air storage tank, and output port are mounted.
[0012] Using the above solution, this utility model provides a high-speed dispensing controller with a pressure stabilizing tank and digital displays for positive and negative pressure. Gas enters the storage tank through an external gas source inlet and a positive pressure regulating valve, thus ensuring the stability of the gas pressure in the storage tank and providing a clear view for the user. Its function is to ensure that dispensing is not affected by fluctuations in the external gas source, thereby ensuring the consistency of the continuous dispensing process. The negative pressure generated by the negative pressure generator can draw back the glue at the dispensing nozzle, preventing residue from remaining there. Attached Figure Description
