[0002] With the rapid development of industries such as pharmaceuticals, food, packaging, and printing, plate-shaped articles such as cardboard and plastic plates involved need to automatically print anti-counterfeiting numbers, production dates, expiration dates, barcodes, two-dimensional codes, etc. on the surface. In the above inkjet printing process, generally, an inkjet printing device is combined with a conveyor to form an inkjet printer, that is, the conveyor transports the article into place, and the inkjet printing device performs alignment and inkjet printing.
[0003] However, due to the design problem of the frame of the traditional inkjet printer, most of them are two-axis frames with limited movement range. Moreover, due to the front and back sides of the plate-shaped articles during feeding, operators need to pay attention to the front and back sides of the feeding, resulting in low inkjet printing processing efficiency of the plate-shaped articles and high labor intensity. Based on this, the utility model proposes a multi-degree-of-freedom frame mechanism of an inkjet printer. This multi-degree-of-freedom frame integrates the inkjet printing frame and the conveying frame. The inkjet printing frame adopts an X, Y, Z three-axis frame with a larger movement range, while the conveying frame is a combination of two conveying sections and a flipping section. Sensors or cameras are used to detect the front and back sides of the article to be inkjet printed in real time. The article is flipped by the fixture and flipping motor of the flipping section, and then transported by the conveying section to the directly lower side of the inkjet printing frame for inkjet printing processing. The entire process does not require manual material flipping, making the efficiency of the entire inkjet printing production line higher. Content of the Utility Model
