Description

Technical Field

[0001] The utility model relates to the technical field of workpiece transport, in particular to an automatic workpiece transport mechanism. Background Art

[0002] Automatic workpiece transfer mechanisms are commonly used in automated production lines to transfer workpieces from one workstation or device to another to achieve automated production processes. These mechanisms can use a variety of technologies and designs, including conveyor systems, robotic arms, automatic guided vehicles, conveyor lines, and robots. Their design takes into account factors such as production efficiency, workpiece size, weight, and safety to ensure smooth operation and high efficiency during the production process.

[0003] When the transfer mechanism of the prior art transfers a workpiece from one platform to another platform at a different height, it usually needs to use the hydraulic cylinder to intermittently lift and lower to drive the workpiece transfer.

This not only increases the cost, but also may reduce the energy efficiency of the system. At the same time, the start and stop operation of the hydraulic cylinder will cause the internal seals and piston rods to wear more, thereby reducing their life and increasing maintenance costs.

[0032] like Figure 1-Figure 4 As shown, the utility model proposes an automatic workpiece transfer mechanism. On the basis of the above embodiments, this embodiment also records in detail the specific components of the lifting mechanism and its driving method for the transfer transport frame 4.

[0033] like Figure 2 As shown, the lifting mechanism includes a rotating shaft 7, a turntable 8 and a connecting rod 9. A rectangular opening 10 is opened in the middle of the transfer platform 1, and a fixed plate 11 located on one side of the rectangular opening 10 is installed at the bottom.
