Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] like Figure 1-5 As shown, an automatic lifting flatbed printer includes a box body 1, a lifting plate 7 is slidably connected to the inside of the box body 1, a vacuum suction plate 6 is fixedly connected to the upper end of the lifting plate 7, a lifting assembly is fixedly connected to the lower end of the lifting plate 7, a clamping assembly is fixedly connected to the inside of the lifting plate 7, one end of the clamping assembly is rotatably connected to multiple clamping rods 17, one end of one side of the clamping rod 17 is fixedly connected to a clamping plate 18, the box body 1 is fixedly connected to multiple translation support plates 8, and one side of the translation support plate 8 is slidably connected to the multiple clamping rods 17;

[0031] The clamping assembly includes a clamping motor 23, a turntable 24 and a connecting rod 25. One end of the clamping motor 23 is fixedly connected to the lifting plate 7, one end of the air guide tube 14 is fixedly connected to the power output end of the clamping motor 23, and the two ends of the connecting rod 25 are rotatably connected to the clamping rod 17 and the turntable 24 respectively.

[0032] The lifting assembly includes a screw nut 9, a lifting bracket 10, a lifting motor 11 and a high-precision screw 12. One end of the screw nut 9 is fixedly connected to the bottom of the lifting plate 7, one end of the lifting motor 11 is fixedly connected to the inside of the box 1, one end of the high-precision screw 12 is fixedly connected to the power output end of the lifting motor 11, one end of the lifting bracket 10 is fixedly connected to the top of the lifting motor 11, one end of the screw nut 9 is threadedly connected to the high-precision screw 12, and the other end of the screw nut 9 is slidably connected to the lifting bracket 10;

[0033] Infrared sensors 16 are fixedly connected to both sides of the box body 1, and a detection slot 19 is opened on one side of the clamping plate 18;

[0034] Before printing, the workpiece to be printed needs to be placed on the vacuum suction plate 6, and then the distance is measured by the infrared sensors 16 on both sides. The infrared sensors 16 on both sides emit light on one side and receive light on the other side. When the infrared light is blocked, it means that the printed workpiece is too high. At this time, the lifting motor 11 works, and drives the lifting bracket 10 to move downward through the high-precision screw 12, and then drives the workpiece downward through the lifting plate 7 and the vacuum suction plate 6. When the light between the infrared sensors 16 is no longer blocked, it means that the printed workpiece has been lowered to the printing height and printing stops;

At this time, the shaking and displacement caused by the up and down movement can be avoided, and there is no need to manually adjust the position, which speeds up the processing efficiency.

[0036] The detection groove 19 at one end of the clamping plate 18 can prevent the clamping plate 18 from blocking the infrared sensor 16 after moving to the uppermost position.

Before printing, the workpiece to be printed needs to be placed on the vacuum suction plate 6, and then the distance is measured by the infrared sensors 16 on both sides. The infrared sensors 16 on both sides emit light on one side and receive light on the other side. When the infrared light is blocked, it means that the printed workpiece is too high. At this time, the lifting motor 11 works, and drives the lifting bracket 10 to move downward through the high-precision screw 12, and then drives the workpiece downward through the lifting plate 7 and the vacuum suction plate 6. When the light between the infrared sensors 16 is no longer blocked, it means that the printed workpiece has been lowered to the printing height and printing stops;

[0042] At this time, the clamping motor 23 works, and the rotating turntable 24 drives the multiple clamping rods 17 to move inward, so that the clamping plates 18 on both sides move inward at the same time to fix the workpiece in the middle of the vacuum suction plate 6. At this time, the shaking and displacement caused by the up and down movement can be avoided, and there is no need to manually adjust the position, which speeds up the processing efficiency.

[0043] The detection slot 19 at one end of the clamping plate 18 can prevent the clamping plate 18 from blocking the infrared sensor 16 after moving to the uppermost position;

[0044] The second clamping plate 20 can move inward on the other side following the clamping rod 17 to clamp and stabilize the workpiece from the other side. At the same time, the spring 22 and the stabilizing rod 21 can have a buffering effect and can clamp workpieces of different lengths and widths.
