Abstract

The invention provides a fluid injection valve and is applied to the field of liquid trace injection devices. Compared with an existing fluid injection valve, an upper end lever and a lower end leverwhich can swing up and down are arranged in the fluid injection valve, the top of a valve body is provided with an adjusting screw, the adjusting screw is screwed, and the adjusting screw can move upand down. When the adjusting screw moves up and down, the bottom of the adjusting screw presses the upper end lever, so that the upper end lever is inclined relative to the horizontal direction, the angle range of the horizontal inclination of the upper end lever is large, and the angle range of the swing of the lever at the lower end of piezoelectric ceramic is directly influenced. If displacement deviation occurs in the lower end lever, only the adjusting screw needs to be screwed, the angle range of the swing of the lower end lever can be adjusted, and therefore the up-down displacement deviation of the lower end lever can be corrected. Therefore, according to the fluid injection valve, the rapid correcting operation can be realized only by screwing the adjusting screw, and the operation difficulty is low. Meanwhile, the adjusting screw is located at the top of the valve body, and the periphery of the adjusting screw is free of objects, so that the debugging operation is convenientand rapid.

Description

technical field [0001] The invention belongs to the field of liquid micro-injection devices, in particular to a fluid injection valve. Background technique [0002] A fluid injection valve is a device that can eject extremely small amounts of liquid material at high speed, which can be applied to microelectronic packaging. The fluid injection valve can be divided into pneumatic type and piezoelectric type according to different power sources. Piezoelectric injection valves utilize the inverse piezoelectric effect of piezoelectric materials, have high injection frequency, simple equipment structure, and injection can obtain glue dots with a diameter as small as 0.2mm; on the other hand, the piezoelectric structure has high control precision and can Improve jet dispensing quality. [0003] During a long period of operation, the lever that directly hits the striker will have a displacement deviation in the up and down direction, so it needs to be debugged. The current fluid ...
