Full-automatic piston screen printer

Abstract

The invention discloses a full-automatic piston screen printer. The full-automatic piston screen printer comprises a loading correcting mechanism, a loading mechanism, a printing mechanism, an unloading mechanism and a sorting mechanism which are all sequentially arranged; the loading correcting mechanism sequentially comprises a positioning mechanism, a direction detecting camera, a position correcting mechanism and a loading conveyor belt which sequentially conveys a piston to the positioning mechanism, the direction detecting camera, the position correcting mechanism and the loading mechanism; the printing mechanism comprises a screen which can carry out reciprocating motion left and right, a printing head which can carry out reciprocating motion up and down and a four-station rotary plate used for connecting the loading mechanism, the printing head and the unloading mechanism; the sorting mechanism sequentially comprises a quality detecting camera, a sorting mechanical arm and an unloading conveyor belt which conveys the piston put by the unloading mechanism to the quality detecting camera and the sorting mechanical arm sequentially, and the two ends of the sorting mechanical arm are provided with a finished product stacking region and a waste material stacking region respectively. According to the full-automatic piston screen printer, manual loading is rapid and convenient, positioning of the piston is accurate, the printing quality is guaranteed, sorting is conducted automatically, and a large amount of labor can be saved.

Description

technical field [0001] The invention relates to a fully automatic piston screen printing machine. Background technique [0002] As an important part inside the engine, the piston has high machining accuracy and a huge market demand. In order to increase the initial running-in performance of the engine, it is necessary to print a layer of graphite or resin material on the piston skirt. At present, most of the piston printing equipment on the market adopts the principle of curved surface printing. Loading and unloading are all done by hand. In order to ensure that the printing position meets the process requirements, workers need to accurately position the piston and ensure that the direction of the piston is consistent during loading. After unloading, manual work is required. Inspect the print quality, which is inefficient and labor-intensive. [0003] And with the development of the piston production industry, the material for piston printing has gradually changed from gra...

At present, most of the piston printing equipment on the market adopts the principle of curved surface printing. Loading and unloading are all done by hand. In order to ensure that the printing position meets the process requirements, workers need to accurately position the piston and ensure that the direction of the piston is consistent during loading. After unloading, manual work is required. Inspect print quality, resulting in inefficiency and high labor costs

[0003] And with the development of the piston production industry, the material for piston printing has gradually changed from graphite to resin material. The performance of resin material is better than that of graphite, but due to its poor fluidity, the printing difficulty is relatively increased. The traditional printing graphite material Piston printing machine can not complete the printing of resin materials
