Abstract
Description
Technical Field
[0001] This utility model relates to the field of dispensing controller technology, and in particular to a high-precision dispensing controller with a fully digital adjustment of positive and negative pressure proportional valves with air storage. Background Technology
[0002] A typical pneumatic dispensing controller is equipped with a pressure reducing valve as the main component for air pressure regulation. It is paired with a digital pressure gauge or a built-in pressure sensor connected to the outlet of the pressure reducing valve to detect the positive / negative air pressure and provide feedback. The user then makes corresponding adjustments based on the value.
[0003] As the dispensing process progresses, if the fluid volume in the dispensing tube decreases while maintaining constant air pressure, it will generally lead to variations in the unit dispensing volume, making it difficult to guarantee dispensing consistency. Operator intervention is required to readjust dispensing parameters and air pressure values, and multiple tests must be conducted to further meet process requirements. This process may repeat itself multiple times, affecting both dispensing consistency and wasting production time.
[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-precision dispensing controller with a fully digital adjustment of positive and negative pressure proportional valves with air storage, so as to solve the problems mentioned in the background art.
[0006] The technical solution of this utility model is as follows: A high-precision dispensing controller with a fully digitally adjustable positive and negative pressure proportional valve and a gas storage unit is provided, comprising: a main board, an external gas source input port, an integrated gas circuit component, a high-frequency multi-position solenoid valve, a negative pressure automatic adjustment proportional valve, a positive pressure automatic adjustment proportional valve, an output port, a first gas pressure sensor, and a second gas pressure sensor; the integrated gas circuit component includes: a gas storage cylinder and a negative pressure generating device; the first gas pressure sensor is used to detect the gas pressure output from the gas storage cylinder, and the second gas pressure sensor is used to detect the negative pressure generated by the negative pressure generating device; the external gas source input port is connected to the gas storage cylinder through a pipeline, the gas storage cylinder is connected to the positive pressure automatic adjustment proportional valve through a pipeline, and the negative pressure generating device is connected to the negative pressure automatic adjustment proportional valve through a pipeline; the high-frequency multi-position solenoid valve is connected to the negative pressure automatic adjustment proportional valve, the positive pressure automatic adjustment proportional valve, 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, the negative pressure automatic adjustment proportional valve, the positive pressure automatic adjustment proportional valve, the negative pressure generating device, the first gas pressure sensor, and the second gas pressure sensor respectively.
[0007] The air pressure and flow rate are precisely controlled by automatic negative pressure and automatic positive pressure regulating valves. Based on different dispensing requirements, the adhesive quantity can be precisely controlled by setting the adhesive ratio parameters. When the first and second air pressure sensors detect that the air pressure deviates from the preset optimal air pressure range, the automatic negative and positive pressure regulating valves will immediately activate. These valves, through a main board connected to the first and second air pressure sensors, regulate the air pressure in the air storage cylinder and the negative pressure generated by the negative pressure generator, thereby regulating the gas pressure entering the dispensing system and quickly restoring it to the preset optimal air pressure range.
[0008] The fully digitally adjustable high-precision dispensing controller with air storage for positive and negative pressure proportional valves further includes: a housing, a main board, an external air source input port, an integrated air circuit component, a high-frequency multi-position solenoid valve, a negative pressure automatic adjustment proportional valve, a positive pressure automatic adjustment proportional valve, and an output port mounted on the housing.
[0009] The fully digitally adjustable high-precision dispensing controller with air storage and positive / negative pressure proportional valve further includes a display screen electrically connected to the main board, the display screen being mounted on the housing. The display screen is used to display various data information (such as air pressure data and working mode indicator lights).
[0010] The fully digitally adjustable high-precision dispensing controller with integrated positive and negative pressure proportional valve and air storage is positioned above the integrated air circuit component. This allows for better optimization of the product's internal component layout.
[0011] By adopting the above solution, this utility model provides a high-precision dispensing controller with a fully digital adjustment of positive and negative pressure proportional valves and air storage, which has the following technical effects:
[0012] Improved dispensing accuracy and quality: Real-time detection and automatic air pressure adjustment ensure stability during dispensing, effectively preventing uneven dispensing volume caused by air pressure fluctuations and improving dispensing accuracy. Furthermore, precise real-time air pressure detection and automatic adjustment, along with accurate control of the adhesive volume using negative and positive pressure automatic adjustment proportional valves, ensure stable and compliant dispensing volume, thereby improving product dispensing quality.
[0013] Improved production efficiency: The automatic adjustment function reduces the time and workload of manual air pressure adjustment, enabling the dispensing process to be carried out more continuously and efficiently, meeting the needs of large-scale automated production and improving production efficiency.
