Dispensing device for printed circuit board processing

Abstract

The utility model discloses a dispensing device for processing a printed circuit board, which comprises a rack, a conveyor belt is mounted in the rack, a first frame and a second frame are arranged at the top of the rack, an air blower and a mounting box which are communicated with each other are arranged at the top of the second frame, one end of the mounting box is communicated with an output pipe, and the other end of the mounting box is communicated with a motor. The bottom of the output pipe penetrates through the second frame to be connected with a first hose, the bottom of the first hose communicates with an air outlet header pipe, the bottom of the air outlet header pipe communicates with a plurality of air outlet branch pipes distributed at equal intervals, a driving motor is further arranged at the top of the second frame, and an output shaft of the driving motor penetrates through the second frame to be connected with a threaded rod. By means of the arrangement, colloid on circuit board welding spots can be rapidly cooled and solidified, the colloid solidification efficiency is improved, the wind force borne by the circuit board can be controlled so as to adapt to the cooling and solidification process after different circuit boards are subjected to glue dispensing, and the application range of the device is widened.
