Anti-dripping and anti-splashing device for printed circuit nozzle

Abstract

The invention discloses an anti-dripping and anti-splashing device for a printed circuit nozzle; the device comprises a spray cylinder, an etching mechanism is arranged in the spray cylinder, the etching mechanism comprises a hydraulic cylinder, a sliding column, a bead groove, a ball, a sponge sleeve, a broken line opening, a rubber plug, a pressing column, an etching head, a spray nozzle and a rectangular liquid outlet pipe, and the upper surface of the spray cylinder is fixedly connected with the hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected with a hydraulic rod, the hydraulic rod penetrates and extends out of the side wall of the upper end of a spraying barrel and is fixedly connected with a sliding column, a plurality of sets of bead grooves are formed in the side face of the sliding column, the bead grooves are distributed at equal intervals in an annular array mode, and etching liquid flowing into the rectangular liquid outlet pipe flows out of the spray nozzle and flows to the etching head. The etching liquid flows downwards along the flow guide groove of the etching head so as to etch the circuit board below, and the amount of the etching liquid flowing out of the nozzle can be effectively controlled by adopting the mode to carry out printing etching operation on the circuit board, so that the amount of the etching liquid flowing out of the nozzle is not too much, and the probability that the etching liquid is splashed is reduced.

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
