Meanwhile, in the process that the positioning plate 732 moves toward the sagger, the positioning assembly 733 is driven to move toward the middle. Because the elastic bending part 7331 of the positioning component 733 protrudes inward, in the process that the positioning plate 732 approaches the sagger, the elastic bending part 7331 contacts the tail end of the sagger, in the process that the positioning plate 732 is further centered, the elastic bending part 7331 generates an elastic force to the sagger, the elastic force can push the sagger to move towards the baffle plate, and until the positioning plate 732 is just centered and adjusted, the elastic bending part 7331 presses the sagger against the baffle plate, so that a gap between the baffle plate and the sagger can be avoided, and the subsequent lamination accuracy is ensured.

Specifically, the cross section of the elastic bending member 7331 is circular arc. The arc shape protrudes toward the transmission mechanism 72, and the protruding portion pushes the sagger when the positioning plate 732 performs centering processing, so that the sagger is pushed to the baffle 741 of the limiting mechanism 74, and the position of the sagger is more accurate. It should be understood that the arc-shaped mode can be used for facilitating relative sliding after being contacted with the saggar. In addition, in order to be able to reduce the influence of the surface of the elastic bending pieces 7331 sagger, the side of the convex portion of each elastic bending piece 7331 has a soft layer 7338. The soft layer 7338 can provide cushioning, and can be made of cotton.
