A self-stabilizing solder paste printing machine that is easy to disassemble

Abstract

The invention discloses a self-stabilizing solder paste printing machine convenient to dismount. The self-stabilization solder paste printing machine comprises a rack, a printing platform, a screen frame assembly, a scrapper mechanism and a control mechanism, wherein the printing platform comprises a support platform, a printing positioning platform and Z-axis lead screws, the printing positioningplatform is mounted on the support platform, X-axis moving tracks and Y-axis moving tracks are arranged on the support platform, the Z-axis lead screws are mounted at four corners of the support platform and sleeved with ball bases, mounting holes are formed in the ball bases, vertical plates are further arranged in the mounting holes and sleeved with reinforcing plates, a plurality of fixed bolts are arranged on the reinforcing plates, the net frame assembly comprises a screen frame and a screen assembly, the screen frame is mounted on the front side and the rear side of the rack through fixed bolts, rollers are arranged on the upper surface of the screen frame, the screen assembly is mounted in the screen frame, and limiting plates are arranged on the screen frame. The self-stabilizingsolder paste printing machine is stable in structure and tightly locked, the rack can be opened and closed, and maintenance, replacement and dismounting of the support plate and the screen assembly are facilitated.

Description

technical field [0001] The invention relates to the technical field of solder paste printing machines, in particular to a self-stabilizing solder paste printing machine which is easy to disassemble. Background technique [0002] The solder paste printing machine is an important executive mechanism in the SMT industry. It is responsible for accurately printing solder paste on the circuit board through the screen of the mold opening during the processing of the printed circuit board. In mass production, it is necessary to make a solder paste printing screen for each version of the printed circuit board, so as to improve production efficiency. [0003] Modern solder paste printing machines generally consist of mechanisms such as plate loading, solder paste addition, embossing, and circuit board delivery. Its working principle is: first fix the circuit board to be printed on the printing positioning table, and then use the left and right scrapers of the printing machine to prin...

Problems solved by technology

However, in the existing devices, when cleaning and replacing parts of different types of devices, the internal structure is not uniform due to inconsistent models, and it is not easy to disassemble and assemble during internal operations, and it is easy to cause The stability of the device after it is disassembled becomes poor. There is no limit structure, and it is difficult to accurately restore the original structure and positional relationship. It is easy to affect the printing effect due to shaking during use
