2, in the middle of the brush-throwing machine place be provided with one up and down movably cutter sit and cutter is taken and installed two the designs that can adjust the scraper of void pitch up and down, be two of technical characterictic of the present utility model.The purpose of doing like this is: the one, because last lower coating blade is that elastic rubber-plastic composite scraper and the blade of going up lower coating blade are the elasticity sword, when two sided pcb is forced to pass through at that time, its elasticity blade is when scraping pressure two sided pcb via, printing ink moment that the via two ends are protruded is blown off, thereby realizes the application's purpose of design; The 2nd, locate and set up a space moving up and down in the middle of two frame support bodies about removable tool rest is arranged on up and down for mobile tool rest, scraper is positioned on the mobile tool rest and scraper can move up and down on tool rest respectively so that adjust space between two cuttves, so that be applicable to the removing of the protruding ink at two ends of conducting hole of printed circuit board of different-thickness.
3, throwing the setting of the adjustable lead of spacing on the live-roller of brushing in the live-roller conveying roller platform, is three of technical characterictic of the present utility model.The purpose of doing like this is: it both can guarantee the bearing accuracy when printed circuit board is carried again according to the channel width of the width adjustment drive transfer roller platform of printed circuit board.
4, the pressure roller governor motion is respectively the design of compressed spring type governor motion, be four of technical characterictic of the present utility model. the purpose of doing like this is: owing to be provided with two scrapers up and down in the middle of brush-throwing machine, by regulating the distance that bolt is regulated upper and lower scraper, this spacing can make printed circuit board be removed by scraper edge by force by two scraper edge the time and with the printing ink that protrude at the conducting hole of printed circuit board two ends.
5, two pressure roller governor motions are respectively the design of compressed spring type governor motion, are five of technical characterictics of the present utility model.The purpose of doing like this is: can regulate spacing between pressure roller and the transfer roller roll surface by regulating bolt, make printed circuit board throwing when brushing, can entirely pass through scraper.
Technical scheme: the brush-throwing machine that is used to remove protruding ink at two ends of conducting hole of printed circuit board, the frame support body is left-right symmetric and distributes, many live-rollers lay respectively in the frame support body of the left and right sides and constitute with the frame support body respectively throws brush live-roller conveying roller platform, the pressure roller governor motion lay respectively at throw on the brush live-roller conveying roller platform and the pressure roller in the governor motion respectively with throw brush live-roller conveying roller platform in the live-roller roll surface be spacing and cooperate, up and down movably the cutter seat in frame support body middle part and cutter take be equipped with about can adjust the scraper of void pitch.
The utility model is compared with background technology, the one, make the printing ink that protrude at the conducting hole of printed circuit board two ends obtain thorough removing, avoided printed circuit board because of of the influence of via two ends owing to protruding ink, and the difficult problem that the product that causes two sided pcb to be caused in the printed wire process is scrapped in a large number, improve the production efficiency of two sided pcb, reduce enterprise's production cost, also be applicable to the removing of one side print via-hole of circuit board protruding ink at two ends simultaneously; The 2nd, structural design novelty, uniqueness, simple, practical are convenient to installation, maintenance, have good value for applications.
