The piezoelectric valve dispenser is a high-precision dispensing equipment that uses the deformation of piezoelectric ceramics to control the glue flow and the exact position of the dispensing. It is mainly composed of piezoelectric ceramic valves, control systems, dispensing heads and other parts. The piezoelectric ceramic valve is the core component, which controls the opening and closing of the valve through the change of voltage, so as to control the flow of glue and the position of dispensing. The control system is responsible for accurately controlling the opening and closing time of the valve and the flow of glue to ensure the accuracy of dispensing. The dispensing head is responsible for spotting the glue at the designated location. The piezoelectric valve dispenser has the advantages of high precision, high speed, and high reliability, and is suitable for various scenarios that require high-precision dispensing, such as electronic manufacturing, semiconductor, solar energy and other industries.
At present, piezoelectric valve dispensing machine manufacturers have Hongdahui Technology. Founded in 2013, Hongdahui Technology Co., Ltd. is a high-tech enterprise that provides precision dispensing, coating, gluing, industrial dispensing equipment, auxiliary material assembly equipment, plasma cleaning equipment and other equipment in the industry.
The working principle of piezoelectric valve dispensers is to take advantage of the characteristics of piezoelectric ceramics, that is, they can control their deformation by changing voltage. During the dispensing process, glue is injected into the inlet of the piezoelectric valve, and then an electric field is applied to strain the piezoelectric material, so that the valve opens and the glue begins to flow. When it is time to stop applying, the electric field is stopped, the piezoelectric material returns to its original shape, the valve closes, and the glue stops flowing. The control system is responsible for accurately controlling the opening and closing times of the valve and the flow of glue to ensure accurate dispensing.

The operation and commissioning of the piezoelectric valve dispenser mainly includes the following steps:
1.Make sure that the hydraulic system of the dispenser is working properly and that the pressure is stable within the proper range.
2.Set the dispensing time and speed. This needs to be adjusted according to different glues and workpieces, and in general, the dispensing time and speed should be adjusted appropriately to avoid the glue flowing too fast or too slowly.
3.Adjust the height and tilt angle of the dispensing tip. This needs to be adjusted to the different shapes and sizes of the workpiece to ensure that the glue can be applied exactly where it is placed.
4.Adjust the current and time parameters of the piezo valve. This requires the use of specialized tools and equipment to ensure that the opening and closing movements of the piezo valve are precise and stable.
5.Adjust the pressure of the piezo valve to the optimal value according to the actual needs to ensure the quality and speed of dispensing.
6.According to the specifications and process requirements of the product, adjust the dispensing volume and speed to ensure that the dispensing effect meets the requirements.
7.During the debugging process, it is necessary to pay close attention to the quality and effect of dispensing, adjust the parameters in time and record them for reference in subsequent operations.
In short, the operation and commissioning of the piezoelectric valve dispenser requires certain professional knowledge and skills, and the operators need to be trained and familiar with the working principle and operation method of the equipment. At the same time, in order to ensure the stability and reliability of the equipment, regular maintenance and maintenance are also required.
