Real-time hook face inkjet printing system and method

Abstract

The invention discloses a real-time hook face inkjet printing system and method. The system includes an inkjet device, a sensor, a mechanical arm and a control device; the inkjet device comprises a spray nozzle and is used for spraying ink to a to-be-printed curved surface; the sensor is connected to the inkjet device and is used for sensing and feeding information of the distance between a current spray nozzle and the to-be-printed curved surface; the mechanical arm has six degrees of freedom and is used for bearing the spray nozzle and the sensor and feeding back current posture informationof the spray nozzle in real time, so that the spray nozzle is capable of being moved to a next position in an appropriate posture for inkjet printing; and the control device is connected to the sensorand the mechanical arm and is used for receiving feedback information of the sensor and the mechanical arm, calculating a motion path and a posture adjustment value of the spray nozzle in real time and controlling the spray nozzle to eject the ink to the to-be-printed curved surface to print a specified pattern. By means of the real-time hook face inkjet printing system and method, real-time printing can be achieved, cost is reduced, hardware configuration and operation steps are simplified, and the application prospect is wide.

Description

technical field [0001] The present invention relates to a real-time curved surface inkjet printing system and method, more specifically, the present invention relates to a system and method for real-time printing on a three-dimensional curved surface by means of six-axis inkjet printing, which belongs to the three-dimensional printing technology field. Background technique [0002] Traditional curved surface printing technologies include screen printing, pad printing, letterpress offset printing, etc., which mainly print on simple and regular curved surfaces, and do not have the ability to print on generally irregular curved surfaces in space, and have problems such as low efficiency, complicated process, and pollution. . Curved surface inkjet printing is a new type of curved surface printing technology, which has unique advantages in curved surface printing. With the increasing market demand for personalized three-dimensional objects, curved surface inkjet printing has bec...

Problems solved by technology

In this way, since a two-dimensional contour scanner is used for scanning, the cost is high, and real-time printing cannot be realized

[0004] Craig Orr et al. disclosed a device and method for printing three-dimensional objects (application publication date: July 09, 2014, application publication number: CN103909743A). This technology also realizes inkjet printing on curved surfaces, but it does not mention The number of sensors, positioning methods, etc., how the sensors used can ensure that the nozzle is perpendicular to the surface to be printed is not specified, and the sensors used are optical sensors including laser sensors. Since the number of sensors is not specified, if one or two sensors are used , can only feed back the distance information of one or two points, and cannot locate the plane where the nozzle is located
