[0002] In modern manufacturing, nuts, as important standard parts, are widely used in multiple fields such as automobiles, machinery, and electronics. The automatic conveying of nuts is a key link to improve production efficiency and reduce labor costs. Especially in large-scale assembly line production, the performance of the nut automatic orienting and conveying device directly affects the assembly quality and production efficiency of products. Currently, the common nut conveying devices on the market mainly include vibrating bowl conveyors and conveyor belt conveyors, etc. The vibrating bowl conveyor makes the nuts move along the track through vibration and realizes preliminary orientation. However, this method has many limitations. First, the conveying efficiency of a single vibrating bowl is relatively low, making it difficult to meet the requirements of large-scale continuous production. Second, for nuts with complex shapes or diverse specifications, the orienting effect of the vibrating bowl is not good, and the nut postures are prone to chaos, resulting in the need for manual secondary adjustment during subsequent assembly, increasing production costs and time costs. For this reason, we propose a multi-station automatic nut orienting and conveying device. Summary of the Invention

The spring support leg 31 can play a shock-absorbing and buffering role; a vibration plate 32 is installed on the upper side of the spring support leg 31, and a push plate 626 is fixed on the lower side of the vibration plate 32, so that the push plate 626 can drive the vibration plate 32 to vibrate under the action of the cam roller 625, and two vibration material trays 33 and a nut buffer box 34 are installed on the upper side of the vibration plate 32, and the inclined plate 1 35, the inclined plate 2 36 and the discharge pipe 37 are installed in the nut buffer box 34 according to the designed position, and the support rod 41 is rotated and connected on the upper side of the support platform 1, and the steering member 63511 is sleeved on the support On the outside of the rod 41, the rotation of the steering member 63511 can drive the support rod 41 to rotate, a circular material box 42 is installed at the top of the support rod 41, and a material guide pipe 43 set at an oblique angle is installed on one side of the circular material box 42 to complete the installation of the nut material transfer part 4, and the support frame 51 of the nut conveying part 5 is installed below the material guide pipe 43, and the synchronous conveyor belt 52 is connected to the transmission roller 644 to ensure that the synchronous conveyor belt 52 can run smoothly under the drive of the transmission roller 644; a partition plate 53 is installed on one side of the support frame 51 to make it conflict with the synchronous conveyor belt 52, and two discharge channels 54 are set on one side of the partition plate 53, and a retaining bar 55 is installed on the upper side of the support frame 51. In this embodiment, the driving motor 611 is started by the intelligent controller 2. The driving motor 611 operates to generate power, which is transmitted to the transmission rod 613 through the coupling 612, causing the transmission rod 613 to start rotating. After the transmission rod 613 rotates, it drives the vibration driving assembly 62, the steering driving assembly 63, and the synchronous conveyor belt driving assembly 64 to work respectively. Nut vibration feeding process: The transmission rod 613 drives the first bevel gear 621 to rotate. The first bevel gear 621 meshes with the second bevel gear 622, causing the second bevel gear 622 to rotate, and then driving the first connecting rod 623 and the cam roller 625 to rotate. During the rotation of the cam roller 625, due to its special contour, it continuously pushes the push plate 626 to make a reciprocating motion.
