[0002] As we all know, mobile phones can be used in a wide range of portable telephone terminals. The circuit board printing device for mobile phone production is an auxiliary device for printing solder paste on mobile phone circuit boards. It has been widely used in the field of electronic product processing. use; the existing mobile phone production circuit board printing device includes a workbench, a mask and a scraper, the bottom of the workbench is provided with a set of legs, the top of the workbench is provided with a placement plate, and the top of the placement plate is set There are positioning slots; when the existing circuit board printing device for mobile phone production is used, the circuit board is placed in the positioning slot, then the mask is covered on the top of the circuit board and the mask is positioned through the positioning slot, and the solder paste is placed On the top of the mask, scrape the solder paste on the top of the mask evenly with a scraper, the solder paste is attached to the circuit board through the die holes on the mask, then take the mask out of the positioning groove, and then position the circuit board It can be taken out from the slot; in the use of the existing circuit board printing device for mobile phone production, it is found that there is a gap between the circuit board and the mask during the printing process, resulting in solder bridges, affecting the quality of the product, resulting in low practicability; and It is easy to scratch the solder paste of the circuit board when taking out the mask, and it is convenient to take out the circuit board from the positioning slot, resulting in low reliability
