During the pumping of each chamber 410, the support roller 411 affects the flow direction of the gas flowing into the chamber 410 through the air hole 345, and the corresponding air holes 345 communicating with the respective chambers 410 cause uneven suction. Thereby, it is ensured that the suction force generated by the corresponding air holes 345 communicating with the respective chambers 410 is the same, and the suction force generated by the air holes 345 can uniformly adsorb the material to be tested 10.

As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 7 , in the present embodiment, the conveyor belt 34 defines a plurality of adsorption zones 346 spaced apart from each other, and the air holes 345 are formed in the adsorption zones 346. Each adsorption zone 346 is used for adsorption For the material to be tested 10, the shape of each adsorption zone 346 is equivalent to the shape of the material to be tested 10.

A situation in which the outside of the belt 34 is continuously pumped is generated. It should be noted that, if the suction force generated by the air hole 345 can stably adsorb the material to be tested 10, the shape of the adsorption region 346 can also be different from the shape of the material to be tested 10 when the adsorption region 346 is designed, and the adsorption region 346 The size can also be smaller than the blank 10 to be tested.

In the present embodiment, the conveying belt 34 of the conveying device 30 is in a state of continuous rotation, and the feeding conveyor belt 12 is in an intermittently rotating state. Therefore, as long as the timing of the rotation of the feeding conveyor belt 12 is set, the feeding conveyor belt 12, one piece of the to-be-tested web 10 is sequentially conveyed to the corresponding adsorption zone 346 of the conveyor belt 34, and each of the to-be-tested webs 10 is accurately stacked on the corresponding adsorption zone 346. During the continuous rotation of the conveyor belt 34 of the conveying device 30, since the suction member 421 continuously sucks the respective chambers 410 of the adsorption cartridge 41, when the conveyor belt 34 carries the adsorption zone 346 of the material to be tested 10 When moving to a position corresponding to the partial chamber 410, the corresponding air hole 345 in the adsorption area 346 communicating with the aforementioned partial chamber 410 generates suction suction The lower surface 102 of the web 10 is attached such that the lower surface 102 of the web to be tested adjacent to the rear end is first flattened on the outer surface 343 of the conveyor belt 34. When the adsorption zone 346 is moved backward, so that more air holes 345 in the adsorption zone 346 are in communication with more of the chambers 410, the area of the lower surface 102 of the test piece 10 to be adsorbed by the air holes 345 is increased. The larger the outer surface 102 is, the larger the area of the lower surface 102 is evenly attached to the outer surface 343.

As shown in FIG. 1 and FIG. 8, when the adsorption zone 346 is moved to a position directly above the adsorption cartridge 41, all the air holes 345 of the adsorption zone 346 are in communication with the chambers 410, and the lower surface 102 is vented by the air holes 345. The adsorbed area is in the maximum state, at which time the lower surface 102 of the web 10 to be tested is completely flatly attached to the outer surface 343 of the conveyor belt 34. Since the adsorption cartridge 41 of the present embodiment has a rectangular shape and its length extending in the front-rear direction is greater than the length of the optical detecting device 14 extending in the front-rear direction, when the conveyor belt 34 drives the material to be tested 10 through the optical detecting device 14, The material to be tested 10 is adsorbed by the air holes 345 of the adsorption zone 346, so that the lower surface 102 of the material to be tested 10 is completely flatly attached to the outer surface 343 of the conveyor belt 34, whereby the optical detecting device 14 is to be tested. When the upper surface 101 of the web 10 is inspected, the accuracy of detection can be effectively improved.

As shown in FIG. 9 and FIG. 10, it is a second preferred embodiment of the transport device of the present invention.

To adjust the height position of the stack of the material to be tested 10.

The conveying mechanism 3 of the conveying device 30 of the present embodiment and the suction cartridge 41 are disposed in the opposite direction to the first preferred embodiment, that is, the opening of each chamber 410 of the adsorption cartridge 41 faces downward. The conveying mechanism 3 can be supported on the ground through a support frame (not shown) or suspended from the ceiling through a suspension mechanism (not shown), so that the conveying mechanism 3 and the adsorption box 41 can be stably held at intervals in the lifting device 15 The position of the stack of the to-be-tested web 10 and the position above the infeed conveyor 12 is carried, whereby the conveying device 30 can sequentially convey the stack of the to-be-tested sheets 10 to the infeed conveyor 12 one by one. .

As shown in FIG. 9, FIG. 10, FIG. 11 and FIG. 12, one of the stack of the to-be-tested materials 10 carried by the carrier 152 is located at the topmost position of the material to be tested 10 in a predetermined order as shown in FIG. In the height position, the material to be tested 10 is adjacent to the outer surface 343 of the conveyor belt 34, so that the suction force generated by the corresponding air hole 345 in the conveyor belt 34 above the material to be tested 10 can move the material to be tested 10 to The upper surface 101 of the material to be tested 10 is flatly attached to the outer surface 343 of the conveyor belt 34. Then, the conveyor belt 34 moves the material to be tested 10 in the direction of the conveying direction I toward the feeding conveyor belt 12.

When moving to the position corresponding to the chamber 410 of the rearmost end, about half of the area of the material to be tested 10 is positioned above the infeed conveyor belt 12. When the conveyor belt 34 is driven to gradually move away from the chamber 410 of the suction box 41 at the rear end, the area of the upper surface 101 of the material to be tested 10 adsorbed by the air holes 345 is gradually reduced, so that the area to be measured is gradually reduced. The force of the web 10 being adsorbed is also gradually reduced. When the downward force of the material to be tested 10 is greater than the suction force of the air hole 345 of the conveyor belt 34, since more than half of the area of the material to be tested 10 is located on the feeding conveyor belt 12 Above, therefore, the material to be tested 10 will be dropped onto the feeding conveyor belt 12 at this time, and at this time, a feeding operation of the material to be tested 10 is completed.
