Problems solved by technology

However, the problem that exists objectively is that when the ink is inserted into the via hole of the double-sided printed circuit board to protect the copper wall, the ink at both ends of the via hole protrudes and leaks, which leads to the leakage of the printed circuit board. Graphical circuit printing cannot be successfully completed during the circuit printing process, and a large number of products are scrapped due to the inability to complete the process smoothly

Embodiment 1

[0015] Embodiment 1: refer to figure 1 with 2 . The brush throwing machine used to remove the protruding ink at both ends of the through hole of the printed circuit board. The frame support body 5 is symmetrically distributed on the left and right. 5 constitutes the conveying roller table of the brush-throwing driving roller, and the conveying roller table of the brush-throwing driving roller located in the support body 5 of the left and right racks is driven by the motor 1 to rotate through the sprocket and chain 2 transmission mechanisms respectively; The rollers 3 and 4 are provided with adjustable spacing guide posts 19 and 20 . The two pressure roller adjustment mechanisms are respectively located on the brush-throwing drive roller conveying roller table, and the pressure rollers 8 and 9 in the adjustment mechanism are respectively spaced from the drive rollers 3 and 4 in the brush-throwing drive roller conveying roller table. They are spring-loaded adjustment mechanis...

Embodiment 2

[0016] Embodiment 2: On the basis of Embodiment 1, the method for removing the protruding ink at both ends of the through-hole of the printed circuit board, the brush-throwing drive roller conveying roller table on the brush-throwing machine is driven by the motor through the sprocket wheel and the chain transmission mechanism. And when the double-sided printed circuit board is transported to the relative gap formed by the upper and lower scraper blades of the polishing machine, the double-sided printed circuit board is forced to pass through the upper and lower scrapers under the action of the transmission roller table of the polishing transmission roller. At the moment of the blade, the scraper scrapes out the ink protruding from both ends of the via hole.

Abstract

The invention relates to a brush-throwing machine for removing protruding ink at two ends of a conducting hole of a printed circuit board, which can effectively remove and throw the ink at two ends of the conducting hole of the double-surface printed circuit board. Frame supporting bodies are arranged in an eudipleural way, a plurality of drive rolls are respectively positioned in the left frame supporting body and the right frame supporting body and respectively form brush-throwing drive roll conveying platforms together with the frame supporting bodies, press roll adjusting mechanisms are respectively positioned on the brush-throwing drive roll conveying platforms; press rolls in the adjusting mechanisms are respectively matched with roll surfaces of the drive rolls in the brush-throwing drive roll conveying platforms in a spacing way; and a tool post moving up and down is positioned in the middle of the frame supporting bodies and provided with a scraping cutter adjusting the spacing up and down. The invention thoroughly removes the protruding ink at two ends of the conducting hole of the printed circuit board, avoids the difficulty of large-tonnage product reject of the printed circuit board during the circuit printing because of the protruding ink at two ends of the conducting hole, improves the production efficiency of the printed circuit board, and lowers the enterprise production cost.

Description

technical field [0001] The invention relates to a brushing machine and a cleaning method for removing ink protruding from both ends of a conducting hole of a printed circuit board, and belongs to the field of manufacturing equipment for removing ink protruding from both ends of a conducting hole of a double-sided printed circuit board. Background technique [0002] At present, the double-sided printed circuit board industry adopts advanced printed circuit board technology to produce printed circuit boards. This technology improves the production efficiency of printed circuit boards and reduces the production cost of enterprises. However, the problem that exists objectively is that when the ink is inserted into the via hole of the double-sided printed circuit board to protect the copper wall, the phenomenon of ink protruding and leaking at both ends of the via hole appears, which leads to the leakage of the printed circuit board. Graphic circuit printing cannot be successfull...
