[0033] The synchronous driving assembly of the automatic positioning assembly 2 moves forward, driving the movable supporting assembly to move forward, which drives the fixed positioning assembly and the elastic positioning assembly to move. The elastic positioning assembly is in a natural state and is separated from the plate. At the same time, the push-out assembly pushes the plate in the fixed positioning assembly out of the fixed positioning assembly, facilitating the plate to be pushed out of the fixed positioning assembly, and facilitating the subsequent material taking equipment to take the material without obstruction. Then, the new plate is placed on the movable supporting assembly, the synchronous driving assembly drives the movable supporting assembly to move, the elastic positioning assembly is inserted into the rear end of the plate, and the front end of the plate is inserted into the fixed positioning assembly, realizing automatic positioning of the plate and adapting to the demand for efficient production. At the same time, the push-out assembly is stretched, having a pushing power.

[0034] The synchronous driving assembly comprises a cylinder 22 and a connecting plate 215. The cylinder 22 is fixedly installed at the top of the front end of the movable bottom plate 21. The driving end of the cylinder 22 is fixedly connected with the connecting plate 215, and the connecting plate 215 is connected with the movable supporting assembly.

[0035] The movable supporting assembly comprises a supporting bottom plate 25, guide rails 29 and movable blocks 216. The guide rails 29 are fixedly installed at the top of the movable bottom plate 21 at equal intervals. The movable blocks 216 are limitingly and slidably connected with the guide rails 29. The supporting bottom plate 25 is fixedly installed at the top of the movable blocks 216. The fixed positioning assembly and the elastic positioning assembly are connected with the supporting bottom plate 25.

[0036] The fixed positioning assembly comprises a fixed cover 210 and a second insertion slot 219. The front end of the supporting bottom plate 25 is fixedly connected with the fixed cover 210.

Without obstruction, this facilitates the subsequent material handling equipment to handle the material, and then the new plate is placed on the support of the movable support component. On the base plate 25, the automatic positioning component 2 drives the connecting plate 215 to move backward. With the cooperation of the guide rail 29 and the movable block 216, the connecting plate 215 drives the supporting base plate 25 of the movable support component to move backward. The supporting base plate 25 drives the fixed cover 210 and the straight plate 27 to move backward. After the first slide rod 23 contacts the rear baffle 24, it stretches the first spring 26. The movable cover 28 moves forward relative to the supporting base plate 25. The first slot 212 of the elastic positioning component is inserted into the rear end of the plate. 8. The plate is pushed forward relative to the support base plate 25 into the second slot 219 of the fixed cover 210. After the plate is inserted into the second slot 219, the plate is automatically positioned. When the plate is inserted into the second slot 219, the plate pushes the push plate 218 to move. The push plate 218 drives the second slide rod 214 to move. The second slide rod 214 drives the mounting block 213 to move. The mounting block 213 drives the second spring 211 to stretch, and the second spring 211 is subjected to energy storage. The push plate 218 has the pushing power.
