By starting the servo motor 5 to drive the gear 6 to drive the toothed disc 8 to rotate, a robotic arm 9 is fixedly connected to the upper surface of the toothed disc 8, so as to adjust the clamping direction. After moving to the bottom of the material, start the first cylinder 11 to drive the pressing plate 12 to press downward.

The telescopic plate 202 is slidably connected to the top of the support rod 201. The top end of the telescopic plate 202 is fixed on the conveying platform 3. By pulling the pull plate 205, the clamping post 204 can easily disengage from the card slot 203 and cooperate with the lifting assembly for lifting processing. When the conveying platform 3 reaches the designated position, by releasing the pull plate 205, the resilience of the spring 207 will cause the clamping post 204 on the pull plate 205 to quickly plug into the card slot 203, thereby completing the fixing process of the support rod 201 and the telescopic plate 202. This not only improves the stability of the conveying platform 3, but also greatly reduces the burden on the lifting assembly, making the entire conveying system more efficient and reliable. Through the cooperation of the support rod 201 and the telescopic plate 202, the bottom of the conveying platform 3 can be fully supported, which not only improves the stability of the conveying platform, but also effectively disperses the pressure of the lifting assembly, thereby extending the service life of the entire conveying device.
