Moreover, the sensor can be realized by using a photoelectric sensor.

In this solution, the overturn frame 2 is further provided with a substrate frame 5, and the substrate frame 5 is provided with a locking mechanism 51 for clamping the workpiece thereon. The substrate rack is used as the carrying plate for transferring and turning over, and different substrate racks can be replaced for workpieces with different size requirements, so that it can be applied to the production and transportation lines of workpieces with different specifications.

The specific structure of the substrate holder is that the substrate holder 5 at least includes an upper positioning portion 501 and a lower positioning portion 502, and the inner side of the upper positioning portion 501 and the lower positioning portion 502 is provided with a boss 503 for carrying workpieces. The lower end of the lower positioning part 502 is located on the second conveying mechanism 4, the upper end of the upper positioning part 501 is opposite to the clamping positioning mechanism 21, and the upper positioning part 501 and the lower positioning part 502 are provided with the The locking mechanism 51. Moreover, in this solution, the flip frame 2 also includes side edges 504 connected on both sides of the upper positioning part 501 and the lower positioning part 502, and several inclined guide blocks 503a are arranged on the side edges 504, and the A cavity is formed between the upper positioning part 501 , the lower positioning part 502 and the two sides for the first conveying mechanism 4 to move up and down. The first conveying mechanism rises to make the conveying plane higher than the substrate frame, so that the turning frame does not block the workpieces transported from the conveying line, and the workpieces can be directly placed on the first conveying mechanism. When transported in place, the first conveying mechanism The workpiece on it is lowered, and the workpiece falls onto the bosses of the upper positioning part 501 and the lower positioning part 502, so that the first transportation mechanism is separated from the workpiece, and the workpiece can be positioned on the flip side by locking the workpiece through the clamping and positioning mechanism. on the shelf.
