The printing device 40 is disposed on one side of the frame 10, and the printing device 40 is partially located above the guide rail 20, and the printing device 40 is used for printing on a printing material. The height detection device 50 is disposed at one side of the printing device 40, the height detection device 50 is located above the guide rail 20, and the height detection device 50 is used for detecting whether the height of the printing material on the bearing table is too high.

Specifically, the height detection device 50 detects whether the height of the print-receiving member is too high before the drive device drives the pad 30 to move below the printing device 40, and then the printing device 40 prints the print-receiving member when the height of the print-receiving member is not too high.

It is worth mentioning that: the upper side of the guide rail 20 means a side of the guide rail 20 facing the pad 30, and the lower side is opposite to the upper side.

S1012: one surface of the printing piece is attached to a bearing platform 32 of the printing platform 30, wherein the part of the printing piece protruding out of the edge of the bearing platform 32 is attached to or close to the base platform 31.

In order to realize that one surface of the printing piece is attached to the bearing table 32 of the printing table 30, the part of the printing piece protruding out of the edge of the bearing table 32 is attached to or close to the base table 31, non-setting adhesive can be coated on four edges of one surface of the printing piece, after the four edges of one surface of the printing piece are fixed with the base table 31, the printing piece can be pulled to be attached to the bearing table 32 in a close fit manner, of course, the part of the printing piece attached to the bearing table 32 can also be coated with the non-setting adhesive, so that the printing piece and the bearing table 32 are also bonded and fixed.

In the embodiment of the present invention, the printing element is fixed on the bearing table 32, the portion of the printing element protruding out of the edge of the bearing table 32 is fixed on or close to the base table 31, the printing table 30 is moved to the lower side of the printing device 40, then the printing device 40 is controlled to perform a printing operation on the printing element, the printing element after printing is separated from the bearing table 32, and printing on the printing element is achieved, because the area of the surface of the bearing table 32 facing away from the guide rail 20 is smaller than that of the surface of the base table 31 facing away from the guide rail 20, when the printing element is borne on the bearing table 32 and the edge of the printing element protrudes out of the bearing table 32, under the action of gravity, the edge of the printing element drops, and the risk that the edge of the printing element tilts up is reduced, thereby reducing the risk that the edge of the printing element scratches the nozzle of the printing device.

Referring to fig. 1, 4 and 8 together, fig. 8 is a flow chart illustrating a printing method according to another embodiment of the present invention, which is different from the above embodiment in that before the step of moving the printing pad 30 to the lower side of the printing device 40, the printing method further includes:

s1013, moving the printing platform 30 to the lower part of the height detection device 50;

s1014, controlling the height detection device 50 to detect whether the height of the printing piece is too high, if not, entering the step S102, and if so, outputting alarm information.

The height detection device 50 is used for detecting whether the height of the printing piece is too high, outputting alarm information and controlling the printing machine 100 to stop until an operator screeds the raised or arched part of the printing piece.

In an alternative manner of the embodiment of the present invention, as shown in fig. 9, the step of controlling the height detection device 50 to detect whether the height of the printing material is too high further includes:

s10141 detecting whether the printing material exceeds a preset height through the laser output module 51 and the laser receiving module 52 of the height detecting device 50;

if so, determining that the height of the printing piece is too high;

if not, determining that the height of the printing-bearing piece is not too high.

The preset height is the height higher than the bearing table 32, specific data of the preset height is not limited, and the specific data can be determined according to actual conditions and can be scraped to the spray head of the printing device 40. In the embodiment of the invention, before the printing operation is carried out on the printing piece, the height of the printing piece can be detected, if the height of the printing piece is too high, alarm information is output to remind an operator to carry out processing, the printing piece is prevented from being scratched to the printing device 40 due to edge warping or arching, and if the printing piece is not too high, the printing piece is continuously printed, so that the printing piece is prevented from being scratched to the printing device 40 due to edge warping or arching.

Referring to fig. 1, 4 and 10 together, fig. 10 is a flowchart illustrating a printing method according to another embodiment of the present invention, which is different from the above embodiment in that after the step of outputting the warning information, the printing method further includes:

s10142, the printing piece is subjected to floating processing, and then the step of controlling the height detection device 50 to detect whether the height of the printing piece is too high is carried out.

The printing part is trowelled by an operator, or the printing part can be screeded by a pressing plate by a manipulator, so that the printing part is not too high in height. The step of smoothing the print substrate does not necessarily allow the height of the print substrate to be too high, so that the height of the print substrate needs to be checked again after this operation.

In the embodiment of the invention, before the printing operation is carried out on the printing piece, the height of the printing piece can be detected, when the height of the printing piece has an overhigh phenomenon, the alarm information is output and the printing piece is smoothed, and then the height of the printing piece is detected until the printing piece does not have the overhigh phenomenon, so that the printing device 40 is favorably prevented from being scratched by the tilting or arching of the printing piece, the spray head is protected, and the damage is avoided because the spray head is an expensive high-precision device. Moreover, the manual use can be saved, only one cleaning cloth needs to be arranged in the whole process, and the labor cost is low.
