Double-track solder paste printing machine with lifting platform capable of moving forwards and backwards

Abstract

The invention discloses a double-track solder paste printing machine with a lifting platform capable of moving forwards and backwards. The machine comprises a rack. A platform translation module and the lifting platform are arranged in the rack, and the platform translation module drives the lifting platform to move forwards and backwards. The platform translation module comprises a fixing plate,a first motor, a first lead screw, and a first lead screw sliding block. The fixing plate is fixed to the side edge of the rack, the first motor is horizontally fixed to the fixing plate, and the first motor is connected with the first lead screw and drives the first lead screw to rotate. The first lead screw sliding block is arranged on the threaded section of the first lead screw in a sleeving mode and moves forwards and backwards along the threaded section of the first lead screw, the first lead screw sliding block is fixed to the lifting platform, and a linear guide rail is arranged on thefixing plate. The platform translation module is simple and stable in structure, and can be stably drive the lifting platform to move forwards and backwards. Under the condition of double rails, printing can be achieved at any position in a large range without making the platform very long, the printing precision is guaranteed, and the smaller the platform is, the higher the printing precision is.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a double-track solder paste printing machine with a lifting platform that can move back and forth. Background technique [0002] With the increasing precision and miniaturization of electronic products, the PCB (Printed Circuit Board, printed circuit board) production of electronic products must be completed by SMT (Surface Mount Technology, surface mount technology) equipment. In the SMT process manufacturing process, solder paste The printing process is a very critical part, and the solder paste printing process is completed by a solder paste printing machine. [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 to fix the circuit board to be printed on the printing positioning table first, and then use the left and right scrapers of...

Problems solved by technology

[0004] However, the platform of the existing double-track solder paste printing machine can only be lifted up and down, and cannot move back and forth. If you want to print on any position in a wide range, you need to make the platform very long, but this will be because the platform is too long. As a result, the printing accuracy is difficult to control, resulting in poor printing effect
