Problems solved by technology

The tightness of the striker and the nozzle top will not only affect the dispensing effect, but also affect the glue volume of a single point. At present, the tightness of the striker nozzle on the market is adjusted according to experience. This method It is time-consuming to adjust and it is impossible to achieve the same tightness every time.

Embodiment Construction

[0022] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0023] An intelligent control method for the tightness of a piezoelectric ceramic valve striker and nozzle according to the present invention, specifically:

[0024] s1. When the screw sleeve adjustment is started, the striker contacts the nozzle. At this time, the charge of the piezoelectric ceramic changes, and the load current of the controller is collected;

[0025] s2. Establish the model between the load current and the rotation angle of the screw sleeve, so as to calculate the rotation angle value of the screw sleeve; specifically: set the parameters of the controller, place the screw sleeve to a completely relaxed state, and trigger the dispensing stat...

Abstract

The invention relates to a piezoelectric ceramic valve firing pin and nozzle tightness intelligent adjusting method based on a current sensor. According to the piezoelectric ceramic valve firing pin and nozzle tightness intelligent adjusting method, a relative value is obtained by detecting the magnitude of current values in a driver under different tightness and through model calculation, and thetightness between a firing pin and a nozzle is digitally displayed. The piezoelectric ceramic valve firing pin and nozzle tightness intelligent adjusting method is simple and convenient to adjust, good consistency can be achieved, and it is guaranteed that the abutting force between the firing pin and the nozzle is consistent in each dispensing operation, so that the stable dispensing effect andthe accurate glue outlet amount are guaranteed.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramic valves, in particular to the adjustment of the tightness of a nozzle and a striker of a piezoelectric ceramic valve. Therefore, the invention provides an intelligent adjustment method for the tightness of a piezoelectric ceramic valve striker and a nozzle. Background technique [0002] Piezoelectric ceramic injection valve is the core component to realize high-efficiency, high-precision, non-contact dispensing, and it is more and more widely used in the field of electronic packaging. The main structure of piezoelectric ceramic injection valve is composed of valve body, piezoelectric actuator, amplification mechanism and flow channel components. The main principle is: use the amplifier to pass through the deformation of piezoelectric ceramics in the piezoelectric actuator The lever principle is used to amplify and transmit to the injection ram (firing pin) in the flow channel assembly...
