Dynamic distance self-adaptive laser coding machine

Abstract

The invention relates to plate coding equipment, in particular to a dynamic distance self-adaptive laser coding machine. The coding machine comprises a laser coding assembly, a first guide support and a first driving mechanism, and is further provided with a translation mechanism and a distance measuring assembly, wherein the translation mechanism bears the laser coding assembly to move in the second direction so as to be close to or away from the coding side face of a plate stacking pile, the translation mechanism further comprises a translation base fixed to a bearing assembly and a second driving mechanism installed on the translation base and connected with the laser coding assembly; and the distance measuring assembly comprises a distance measuring part and a distance measuring connecting mechanism for connecting the distance measuring part to the laser coding assembly. When the plate stacking pile coding side face is an inclined face, the distance measuring assembly can monitor the distance change between the laser coding assembly and the plate stacking pile coding side face, the second driving mechanism drives the translation base to drive a laser coding mechanism to move so as to adjust the position of the laser coding mechanism, and therefore the situation that codes on multiple layers of plates are different in size and shape, and seams of the plates are coded are avoided, and the coding precision is improved.

Description

technical field [0001] The invention relates to plate coding equipment, in particular to a dynamic distance self-adaptive laser coding machine. Background technique [0002] In the field of sheet metal processing, especially in the manufacturing process of man-made panels, it is often necessary to print information such as the brand and model of the product on the sheet. In order not to affect the state of the surface of the sheet, such information is often printed on the side of the sheet. Existing There are generally two printing methods, one is inkjet printing and the other is laser printing. Inkjet printing is generally set on the conveying line of product processing, and inkjet printing components are set on the path of the plate. This kind of coding The method requires the speed coordination of the inkjet printing components and the plate conveying equipment. The electrical coordination control requirements of the overall equipment are relatively high, and the program ...

Problems solved by technology

[0003] However, due to stacking or transportation reasons, the surface of the palletizing stack facing the laser head is often not a completely vertical plane, but may be a slope that gradually moves away or gradually approaches. Then, when the laser head moves vertically each time, the The distance of the corresponding surface to be coded changes, which will cause inaccurate coding positions on the planes that are out of focus, and easily cause the font size of the coded pattern to be different, or reach the seam of the board, resulting in incomplete coding Case
