An anti-drip and splash device for printed circuit nozzles

Abstract

The invention discloses an anti-drip and splash device for a printed circuit spray head, which includes a spray barrel, and an etching mechanism is arranged inside the spray barrel, and the etching mechanism includes a hydraulic cylinder, a sliding column, a bead groove, a ball, a sponge sleeve, and a folding line. Mouth, rubber plug, pressure column, etching head, nozzle, rectangular liquid outlet pipe, the upper surface of the spray tube is fixedly connected with a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected with a hydraulic rod, and the hydraulic rod extends out of the spray tube The side wall of the upper end is fixedly connected with a sliding column, and several groups of bead grooves are opened on the side of the sliding column, and the several groups of the bead grooves are distributed in a circular array at equal intervals, and the etching liquid flowing into the rectangular liquid outlet pipe flows out from the nozzle And flow to the etching head, and flow down along the flow guide groove of the etching head, so as to etch the circuit board below. Using this method to print and etch the circuit board can effectively control the engraving flow out of the nozzle. The amount of etching solution is reduced so that the amount of etching solution flowing out of the nozzle is not too much, thereby reducing the probability of etching liquid splashing.

Description

technical field [0001] The invention relates to the technical field of nozzles, in particular to an anti-drip and splash device for printed circuit nozzles. Background technique [0002] The meaning of the nozzle is very close to that of the nozzle. One is a common name and the other is a more professional term. The nozzle is a key part, even the main part, of many kinds of spraying, spraying, oil spraying and sandblasting equipment. [0003] The names of the circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in mass production of fixed circuits and optimizing the layout of electrical appliances.

Problems solved by technology

[0004] In the process of making the circuit board, it is necessary to print and etch the relevant lines on the circuit board through the etching machine. In the traditional technology, when the circuit board is etched, the mechanical arm with the etching nozzle of the etching machine is constantly going up and down. Move and break the line, move in parallel, so as to perform intermittent etching at different positions on the circuit board, but the mechanical arm of the etching machine with the etching nozzle moves up after completing one etching and then moves to another position on the circuit board During the process, the etching solution in the nozzle is easy to flow down and splash on the circuit board, so that the circuit board is etched incorrectly
