Therefore, they should not be construed as limitations on this invention.

[0028] A flipping and conveying mechanism, such as Figure 1 and 3As shown, the device includes a frame 1, two transport rails 2, and a tilting assembly 3. The two transport rails 2 are arranged vertically inside the frame 1, and the tilting assembly 3 is located at one end of the frame 1. The tilting assembly 3 includes a gear-driven cylinder 3-1, a driving gear 3-2, a driven gear 3-3, and a clutch 3-4. The gear-driven cylinder 3-1 is pivotally fixed to the outside of the frame 1 via a gear-driven cylinder fixing piece 3-1-1 at its top. A gear-driven cylinder connecting piece 3-1-2 is also provided at the bottom of the gear-driven cylinder 3-1. The driving gear 3-2 is located inside the frame 1 with part of its teeth exposed. The gear-driven cylinder connecting piece 3-1-2 is rotatably fixed to the exposed part of the teeth of the driving gear 3-2. The driven gear 3-3 meshes with the driving gear 3-2 above it, and the number of teeth of the driven gear 3-3 is half that of the driving gear 3-2. The surface is provided with a driven gear locking point 3-3-1; the clutch 3-4 includes a clutch flange 3-4-1, a driven gear locking element 3-4-2, and a clutch actuation cylinder 3-4-3. The driven gear locking element 3-4-2 is rotatably disposed in front of the clutch actuation cylinder 3-4-3, and the other end of the driven gear locking element 3-4-2 away from the clutch actuation cylinder 3-4-3 passes through the clutch flange 3-4-1 to the driven gear locking point. Inside 3-3-1; the end of the clutch push cylinder 3-4-3 away from the driven gear locking member 3-4-2 is fixed on the frame 1; the clutch flange 3-4-1 is also provided with two upper and lower extension guide rails 2-1, the diameter of the extension guide rail 2-1 is the same as the diameter of the transport guide rail 2, and the positions of the extension guide rail 2-1 and the transport guide rail 2 are adapted; the end of the transport guide rail 2 near the extension guide rail 2-1 is provided with a guide rail locking device 2-2.

[0029] Specifically, the structure includes a frame 1, two transport rails 2, and a flipping assembly 3. The two transport rails 2 are arranged vertically inside the frame 1, and the flipping assembly 3 is located at one end of the frame 1. This structure allows the parts to be flipped to be transported within the frame 1 via the transport rails 2 to one end of the frame 1, i.e., the location of the flipping assembly 3. Then, a gear-driven cylinder 3-1 is swayably fixed to the outside of the frame 1 via a gear-driven cylinder fixing part 3-1-1 at its top. The bottom of the gear-driven cylinder 3-1 is also provided with a gear-driven cylinder connecting part 3-1-2, and the driving gear 3-2 is... The gear-driven cylinder connector 3-1-2, located inside the frame 1 with part of its teeth exposed, is rotatably fixed to the exposed teeth of the driving gear 3-2. This allows the gear-driven cylinder 3-1 to move the gear-driven cylinder connector 3-1-2, thereby driving the driving gear 3-2 to rotate. The driven gear 3-3 meshes with the driving gear 3-2 above it, with the number of teeth of the driven gear 3-3 being half that of the driving gear 3-2. This structure ensures that when the gear-driven cylinder 3-1 drives the driving gear 3-2 to rotate 90 degrees, the driving gear 3-2... The driven gear 3-3 completes a 180-degree rotation and has a driven gear locking point 3-3-1 on its surface. The clutch 3-4 includes a clutch flange 3-4-1, a driven gear locking element 3-4-2, and a clutch actuation cylinder 3-4-3. The driven gear locking element 3-4-2 is rotatably disposed in front of the clutch actuation cylinder 3-4-3. The other end of the driven gear locking element 3-4-2, away from the clutch actuation cylinder 3-4-3, passes through the clutch flange 3-4-1 into the driven gear locking point 3-3-1, and is located away from the clutch actuation cylinder 3-4-3. The structure in which one end of the driven gear locking member 3-4-2 is fixed to the frame 1 is used for the clutch actuating cylinder 3-4-3 to push the driven gear locking member 3-4-2 through the clutch flange 3-4-1, so that when the driven gear locking member 3-4-2 enters the driven gear locking point 3-3-1, the driven gear locking member 3-4-2 locks and fixes the driven gear 3-3, that is, restricts the displacement and rotation of the driven gear 3-3. When the driven gear locking member 3-4-2 leaves the driven gear locking point 3-3-1, the restriction on the displacement and rotation of the driven gear 3-3 is released. Furthermore, two expansion guide rails 2-1 are provided on the flange 3-4-1, one above the other. The diameter of the expansion guide rail 2-1 is the same as that of the transport guide rail 2, and the positions of the expansion guide rail 2-1 and the transport guide rail 2 are adapted to each other. The transport guide rail 2 is provided with a guide rail locking device 2-2 at one end near the expansion guide rail 2-1, so that after the workpiece to be flipped on the transport guide rail 2 reaches the expansion guide rail 2-1, the driven gear 3-3 drives the transport guide rail 2 to flip 180 degrees, and the guide rail locking device 2-2 fixes the flipped expansion guide rail 2-1.In the normal state, the guide rail locking device 2-2 locks the extension guide rail 2-1, and the driven gear locking element 3-4-2 moves away from the driven gear locking point 3-3-1. When the flipping action begins, the driven gear locking element 3-4-2 inserts into the driven gear locking point 3-3-1, the guide rail locking device 2-2 releases the extension guide rail 2-1, the gear-driven cylinder 3-1 drives the driving gear 3-2 to rotate and the driven gear 3-3 to complete the rotation, and the driven gear 3-3 drives the extension guide rail 2-1 to complete the flipping action. After the flipping action is completed, the driven gear locking element 3-4-2 disengages from the driven gear locking point 3-3-1, and the guide rail locking device 2-2 locks the extension guide rail 2-1.
