particularly, in order to accelerate the efficiency of the inkjet printing of the workpiece, in the embodiment of the application, the inkjet printing device is provided with at least one pair of nozzles, and the at least one pair of nozzles are symmetrically arranged along the normal of the surface of the tool platform so as to simultaneously perform the inkjet printing on the workpiece, thereby shortening the inkjet printing time of a single workpiece and improving the inkjet printing efficiency of the workpiece. Indeed, in other embodiments, the number of the corresponding nozzles may be selected according to actual situations, such as two pairs or more, as long as the spraying requirements can be met, and the number is not specifically limited herein.
In this embodiment, the inkjet printing device further comprises a support, the support is arranged on the tool platform and can move relative to the tool platform, at least one pair of nozzles is arranged on the support, and the support is moved on the tool platform, so that the at least one pair of nozzles is driven to move to the upper side of the first area.
In other embodiments, other nozzle moving modes can be selected according to actual conditions, if the support is fixedly connected with the tooling platform, at the moment, the nozzle is connected with the support through the moving member, the moving member can move on the support, so that the nozzle connected with the moving member is driven to move relative to the support, at least one pair of nozzles are moved above the first area on the working platform, and as long as the moving requirements of the nozzle relative to the tooling platform can be met, specific limitation is not made here.
S3: adjusting the orientation of at least one pair of the heads so that the liquid ejection trajectory lines of two heads in any pair of the heads have an intersection;
specifically, in order to enable the side surface of the workpiece to be sprayed by the nozzles during inkjet printing, the orientation direction of at least one pair of nozzles relative to the workpiece needs to be adjusted, so that the central axis of each nozzle is inclined relative to the horizontal plane where the workpiece is located, and the inclination direction is inclined towards the position where the workpiece is located, that is, the two nozzles are arranged in a V shape, so that the spraying trajectories of the two nozzles in any pair of nozzles have an intersection point, and thus the spraying trajectories of the nozzles can cover the side surface of the workpiece, at this time, simultaneous spraying of two opposite parallel side edges of the workpiece can be realized, and a shielding layer required for processing is also formed on the side surface of the workpiece. The spraying track line is a line formed by connecting moving tracks of ink sprayed from the spray head in the process of flowing from the spray head to the workpiece.
However, in the method applied in S3, the two nozzles are arranged in an inclined manner, the liquid spraying trajectories have an intersection, when a workpiece with a large thickness is sprayed, the liquid spraying trajectories of the two nozzles can reach the workpiece before intersecting, and when a workpiece with a small thickness is sprayed, the liquid spraying trajectories of the two nozzles can intersect before reaching the workpiece, so that the liquid spraying trajectories on the two liquid spraying trajectories collide with each other to change the spraying direction, and thus the spraying position and the spraying thickness of the liquid spraying on the workpiece cannot be controlled, and the spraying effect and the processing efficiency of the workpiece are affected.
In order to solve the problems in the above technical solutions, in this embodiment, the inkjet printing apparatus further includes a measuring device for measuring the thickness of the workpiece, and the measuring device can measure the thickness of the first region, and then adjust the orientation of at least one pair of nozzles according to the thickness measurement result, so that the liquid ejection trajectories of any pair of nozzles intersect when reaching the surface of the workpiece (as shown in fig. 2, where 1 is the liquid ejection trajectory and 2 is the workpiece), so that the liquid ejection trajectories do not intersect when reaching the surface of the workpiece, thereby achieving the controllability of the spraying position and the spraying thickness of the liquid on the workpiece, and ensuring the spraying effect and the processing efficiency of the workpiece.

The coating composition is not particularly limited as long as it can satisfy the coating requirements.
In order to make the adjustment of the inkjet printing apparatus more convenient and accurate, in this embodiment, the inkjet printing method further includes S4: adjusting the distance of at least one pair of spray heads in the height direction relative to the workpiece, so that the spray trajectory lines of any pair of spray heads are arranged away from each other in the process of reaching the surface of the workpiece;
specifically, after the spray heads are obliquely arranged in the S3, the inclination angle of the spray heads relative to the workpiece is kept unchanged, and the distance between at least one pair of spray heads relative to the workpiece in the height direction is adjusted, so that the spray trajectory lines of any pair of spray heads cannot intersect in the process of reaching the surface of the workpiece, the spraying position and the spraying thickness of the spray liquid on the workpiece are controllable, and the spraying effect and the machining efficiency of the workpiece are ensured. The specific adjusting method at least comprises the following steps corresponding to the adjusting method:
when the inkjet printing apparatus further includes a measuring device for measuring the thickness of the workpiece, the distance of at least one pair of heads with respect to the workpiece in the height direction is adjusted based on the measurement result of the measuring device on the workpiece so that the liquid ejection trajectories of any pair of heads intersect when reaching the surface of the workpiece, thereby ensuring that the liquid ejection trajectories of any pair of heads do not intersect when reaching the surface of the workpiece.
When the first area is the area with the minimum thickness of the workpiece, the distance of at least one pair of spray heads relative to the workpiece in the height direction is adjusted in the first area, so that the spray tracks of any pair of spray heads intersect when reaching the surface of the workpiece, thereby ensuring that the spray tracks of any pair of spray heads do not intersect when reaching the surface of the workpiece
