Description

Technical Field

[0001] The utility model relates to the field of printing tables, in particular to a printing table of a printing press. Background Art

[0002] The application of electronic products has penetrated into all aspects of life, and people's requirements for the manufacturing of electronic products are getting higher and higher, because electronic products are becoming smaller and more precise, and the production of printed circuit boards for electronic products must be completed by surface assembly technology equipment. The first process of its production is solder paste printing, which is completed by a solder paste printer. Therefore, the processing of the first process largely determines the production quality of printed circuit boards. The printed circuit boards in electronic products are generally equipped with many electronic components, such as chips, resistors, capacitors and inductors, in order to form circuits with specific functions. Therefore, multiple soldering points for soldering the above electronic components are set on the printed circuit board. In order to obtain better soldering effects and improve soldering efficiency, a layer of solder paste is first applied to the soldering points of the printed circuit board before soldering the above electronic components. Solder paste printing is an indispensable process, and a solder paste printer is required to print solder paste on the printed circuit board. The working principle of the solder paste printer is to first fix the printed circuit board to be printed on the printing table, and then move the scraper back and forth on the steel mesh to cover the solder paste from the openings on the steel mesh on the printed circuit board, thereby completing the printing work.

[0003] Currently, there are two types of solder paste printers: automatic and manual. Automatic printers are more expensive and suitable for large-scale solder paste printing by larger manufacturers. Manual printers are cheaper and more suitable for small-scale printing by small manufacturers. When using a manual printer, the staff uses a scraper to flatten the solder paste, and cannot ensure that the force applied by the hand is always consistent and appropriate. Too thick solder paste will cause the solder paste to collapse, and too thin solder paste will prevent subsequent welding and other work from proceeding smoothly. In addition, if the steel mesh is used for a long time, its openings will be blocked, resulting in missing prints, and the steel mesh needs to be cleaned and replaced in time. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a printing table of a printing machine, which is characterized by comprising a base, a material loading structure, an adjustment structure, a sliding structure, and a scraping structure.

[0007] The adjustment structure consists of a steel mesh, a fixed shaft A, a fixed shaft B, and an adjustment button. The fixed shaft A is installed on the side of the material table, and the fixed shaft B is installed on the opposite side of the fixed shaft A. The steel mesh is installed between the fixed shaft A and the fixed shaft B, and five adjustment buttons are installed in parallel on one side of the steel mesh.

[0008] The sliding structure is composed of a transverse slide, a transverse base, and a lifting limit platform. The lifting limit platform is installed on one side of the material platform. A transverse slide is arranged on one side of the lifting limit platform, and a transverse base is installed in the transverse slide.
