[0031] like Figure 1 and Figure 2As shown, the horizontal conveying device 2 includes a conveying platform 21, a conveyor belt 22, a driving motor 23 and two tensioning rollers 24. The conveying platform 21 is horizontally arranged along the X-axis direction. The two tensioning rollers 24 are rotatably arranged at both ends of the conveying platform 21. The conveyor belt 22 is sleeved on the two tensioning rollers 24 and tensioned by the tensioning rollers 24. The digital tube circuit board is placed on the upper surface of the conveyor belt 22.
