Screen frame printing ink cleaning device

Abstract

The invention discloses a screen frame printing ink cleaning device which comprises a drive mechanism, a printing ink cleaning mechanism and an outer shell. The outer shell closes the drive mechanism and the printing ink mechanism; the printing ink cleaning mechanism comprises a printing ink cleaning pump and a cleaning liquid spraying pipe; the cleaning liquid spraying pipe is provided with multiple cleaning liquid spraying heads; the printing oil cleaning pump transports the cleaning liquid to the cleaning liquid spraying heads; the drive mechanism comprises a driving motor, two fixed frameworks arranged in parallel, multiple drive shafts, a transmission shaft and an antifouling hood; the drive shafts are vertically arranged on the fixed frameworks; one end of each drive shaft is provided with a first conical wheel; the transmission shaft and the fixed frameworks are arranged in a parallel manner; the transmission shaft is provided with multiple second conical gears; the first conical wheels and the second conical wheels are engaged; the driving motor is used for driving the transmission shaft to rotate; the antifouling hood sleeves the transmission shaft. The screen frame printing ink cleaning device has the characteristics of being reliable to use and long in service life.

Description

technical field [0001] The invention relates to the field of printed circuit board auxiliary tools, in particular to a screen frame ink cleaning device. Background technique [0002] In the process of processing and manufacturing printed circuit boards, screen frames are needed. The screen frames include the screens used in PCB silk screen printing and solder mask processes. The prepared ink prints graphic characters on the surface of the printed circuit board through the screen frame. [0003] The thickness of the screen frame is usually uniform, and the length varies according to the process. The screen frame needs to be reused. Therefore, the ink on the screen needs to be cleaned after the screen frame is used, so as to avoid affecting the reuse of the screen frame after the ink is dried on the screen of the screen frame. [0004] Originally, net frame trough soaking and manual spray cleaning were used, which was labor-intensive, low-efficiency, and the smell of chemical...

AI Technical Summary

Problems solved by technology

[0004] Originally, net frame trough soaking and artificial spray cleaning were used, which was labor-intensive, low work efficiency, strong smell of chemical reagents, not environmentally friendly, and even damaged the health of workers.

With the development of automation technology, automatic cleaning of screen frames has gradually become a development trend. At present, vertical screen frame cleaning devices are generally used. This device includes a transmission mechanism and a cleaning mechanism. The transmission mechanism is driven by a chain, and the screen frame is transported to the cleaning mechanism. Stop the transmission until the cleaning time of the screen frame is over. When the nozzle in the cleaning mechanism is spraying the screen frame, the ink on the screen frame will splash on the chain, but the nozzle has been spraying against the screen frame, failing to clean the chain. , the ink accumulates in the chain and air-dries. After a period of time, the ink on the chain will cause the transmission to be stuck, and the use time is short
