Circuit board printing device for mobile phone production

Abstract

The invention relates to the technical field of mobile phone processing accessory devices, in particular to a circuit board printing device for mobile phone production. It can be guaranteed that a circuit board and a mask are closely attached, a solder bridge is prevented, the product quality is improved, and practicability is improved; and the situation that when the mask is taken out, solder paste on the circuit board is scratched can be effectively prevented, the circuit board is convenient to take out, and the using reliability is improved. The circuit board printing device comprises a box, a hydraulic cylinder, a top plate, a left supporting plate, a right supporting plate, the mask, a lead screw, two sets of limiting rods, a sliding block, a motor, a scraping plate, a hydraulic rod and a ball bearing; a placement plate is arranged on the inner bottom wall of a working cavity, and a mask groove is formed in the top end of the placement plate; a positioning groove is formed in theinner bottom wall of the mask groove; a supporting plate and four sets of supporting devices are arranged in the positioning groove, and each supporting device comprises a supporting box, three sets of supporting columns, a baffle, a spring and a limiting plate; and a taking and placing opening is formed in the front end of the box, and a set of door plates is arranged at the taking and placing opening.

[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
