[0034] When this embodiment is in use, it transports the diffusion plate from the preceding device to the upper conveyor frame 11, wherein the preceding device has a detection device, such as an industrial camera for detection, which is a conventional structure and will not be described in detail here. After the detection is completed, it is a qualified product. At this time, the upper conveyor frame 11 and the transition connecting frame 21 are in a horizontal state, and the diffusion plate is moved along the upper conveyor frame 11 to the transition connecting frame 21 through the pushing device, and then continues to be transported to the right until it moves to the top surface of the first extension plate 53 opposite to the two first cross flip axes 51 of the collection frame 30, and its right end is close to the left side wall of the upper limit baffle 35 to achieve blocking, and it can also be formed on the upper limit baffle 35 The type has a screw-connected through hole, and the proximity switch is screwed into the screw-connected through hole.

The unqualified diffusion plates will be transported along the upper conveyor frame 11 to the top surfaces of the relative extension plates 271 of the two cross-turning shafts 27 and lean against the corresponding limit baffles 25. The limit baffles 25 can be installed with a proximity switch, and its installation structure is the same as the structure of installing a proximity switch on the upper limit baffle 35. This It will not be described in detail here. After the proximity switch on the limit baffle 25 senses the diffusion plate, it is operated by two rotating motors 28 to make the two opposite extension plates 271 flip to the bottom (the cross flip axis 27 rotates 90° each time), so that the diffusion plate at this time falls onto the top lifting plate 41 of the lifting platform 40 directly below (the top lifting plate 41 is at the top at this time), and then, the top lifting plate 41 of the lifting platform 40 descends, and then, the defective products can be pushed out or taken out from the top lifting plate 41 through the subsequent pushing device, which is very convenient.
