Embodiment Construction

[0058] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0059] The inkjet printing method of the color pattern on the workpiece provided by this embodiment comprises the following steps:

[0060] 1) Place the workpiece on the transmission carrier, and the transmission carrier drives the workpiece to move on the set trajectory. The transmission carrier of this embodiment is a conveyor belt, and moves along two circular motion tracks, see figure 1 , figure 2 . Of course, the present application is not limited to two circular motion trajectories, and may also be linear motion trajectories.

[0061] 2) The CCD camera collects the position information of the workpiece on the transmission carrier and the surface pattern of the workpiece, and combines the position information of the workpiece to obtain the printing parameters corresponding to each workpiece according to the set printing pattern.

[0062] 3) ...

Abstract

The invention relates to a spray printing method for color patterns on workpieces. The spray printing method includes the following steps that the workpieces are placed on a conveying carrier, and theconveying carrier drives the workpieces to move according to the set track; position information of the workpieces on the conveying carrier and the patterns on the surfaces of the workpieces are collected through a camera, and printing parameters corresponding to the workpieces are obtained with the combination of the position information of the workpieces and the set printing patterns; and an ink jet printing module conducts spray printing and curing operation on the workpieces in sequence according to the printing parameters, and finally the patterns which are completely the same are formedon the workpieces. The spray printing method has the beneficial effects that the workpieces do not need to be rotated, a special clamp body does not need to be used for achieving accurate positioning, the yield is greatly increased, and any spray printing pattern can be designed according to needs; in addition, coating can be conducted more accurately according to the shapes of the patterns whena bottom layer is coated, metering can also be better controlled to avoid waste, and the rejection rate is reduced; and the overall process is compact, and efficient spray printing is achieved due tothe assembly line design.

Description

technical field [0001] The invention relates to workpiece jet printing, in particular to a method and device for jet printing color patterns on workpieces. Background technique [0002] The surface of the workpiece generally has a color pattern, but in the prior art, when printing on the surface of the workpiece, it is often necessary to adjust the posture of the workpiece (usually rotation adjustment) to achieve the same set posture. , and then use special equipment to carry out multi-process jet printing, and finally form the required pattern. On the other hand, when the workpiece is rotated in actual operation, there are high requirements for the positioning accuracy of the workpiece, and in the subsequent printing process, it is necessary to first coat the surface of the workpiece with an adhesive adhesive. Considering the shape of the pattern, The measurement of the adhesive is not easy to determine, and a large amount of adhesive is often used, resulting in unnecessar...
