In this embodiment, a certain distance is provided between the inner top wall of the driving belt 9 and the top of the bottom light source component 6 (the distance is not required to be too large, as long as the inner top wall of the driving belt 9 and the top of the bottom light source component 6 are not always rubbed, and in order to realize that the material supporting belt can automatically descend to be attached to the upper surface of the bottom light source component 6 after corresponding to the position of the bottom light source component 6, a top block 903 is fixedly mounted in the middle position of the top of the material supporting belt (i.e. in the middle of a third strip 902), a pressing block 504 is fixedly mounted at the bottom of the corresponding limiting block 501, both the pressing block 504 and the top block 903 are arc-shaped, when the pressing block 504 presses the top block 903, the material supporting belt can be driven to automatically descend, and the front-back length of the pressing block 504 is greater than that of the top block 903, so that when the pressing block 504 moves along with the limiting block 501, the pressing effect on the top block 903 can be still played. In actual use, the number of the long strips 902 on the carrier tape can be selected according to the need, and the left and right lengths of the top blocks 903 can be increased, but in order to avoid the top blocks 903 affecting the rotation of the long strips 902 along with the pulley 203, the top blocks 903 are only fixedly connected with the middle long strip 902, but not connected with other long strips 902.
In the present embodiment, it is preferable that: when the starting motor 7 drives the connecting belt 901 and the long strip 902 to move through the cooperation of the structures such as the worm 202, the belt pulley 203 and the long rod 201, the worm 202 drives the two limiting blocks 501 and the two pressing blocks 504 to separate to two sides through the cooperation of the structures such as the long toothed bar 306, the side toothed bar 304, the first bracket 303 and the second bracket 403, and also drives the driving belt 9 at the front side and the rear side to fold to the middle, namely drives the connecting belt 901, the five long strips 902 and the top block 903 at the front side and the rear side to move to the direction of the bottom light source assembly 6; the workpiece is then placed in the middle of the five strips 902 from the right (the initial positions of the five strips 902 correspond to the discharging positions by adjusting the motor 7, which is a well-known technology, and not described in detail here), and the strips 902 cooperate with the connecting belt 901 and the belt pulley 203 to drive the workpiece to move left and start the workpiece conveying.
