Automatic Piston Screen Printing Machine

Abstract

The invention discloses a fully automatic piston screen printing machine, which comprises a feeding and correcting mechanism, a feeding mechanism, a printing mechanism, a feeding mechanism and a sorting mechanism arranged in sequence; the feeding and correcting mechanism successively includes a positioning mechanism and a direction detection camera And the position correction mechanism, and the feeding conveyor belt that sequentially transports the piston to the positioning mechanism, the direction detection camera, the position correction mechanism and the feeding mechanism; the printing mechanism includes a screen that can reciprocate left and right, and a printing head that can reciprocate up and down. The four-station turntable of the feeding mechanism, printing head and unloading mechanism; the sorting mechanism includes the quality inspection camera, the sorting robot arm, and the piston that is put down by the unloading mechanism to the quality inspection camera and the bottom of the sorting robot arm in turn. The material conveyor belt is equipped with a finished product stacking area and a waste stacking area at both ends of the sorting robot arm. The invention has the advantages of fast and convenient material feeding by workers, accurate positioning of the piston, guaranteed printing quality, automatic sorting, and can save a lot of manpower.

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...

Problems solved by technology

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
