Description

Technical Field

[0001] This utility model relates to the field of material transport device technology, and in particular to a material transport unit. Background Technology

[0002] In modern industrial production, automated and intelligent production models have become the mainstream development trend. Various advanced production equipment and systems have emerged to improve production efficiency, reduce labor costs, and ensure product quality. Six-axis robots, due to their flexibility and practicality, are widely used in material handling, assembly, and other processes. During material handling, six-axis robots are often paired with sliding structures to allow them to move flexibly within a certain range, meeting the production needs of different workstations. This is of great significance for improving the automation level and operational efficiency of the entire production system. Existing technologies have produced many such sliding buffer structures, such as the enclosed ground rail feeding system disclosed in patent number CN202122158060.4. This system includes a ground rail and a sliding plate mounted on the upper end of the ground rail. A drive mechanism is installed on the upper end of the sliding plate to propel it along the ground rail. A cable chain with a wire harness is installed on one side of the ground rail. A six-axis robot can be mounted on the sliding plate. During operation, the drive mechanism drives the sliding plate, enabling the six-axis robot to move along the ground rail, improving robot utilization efficiency and achieving automated production.

[0003] In actual working conditions, when a six-axis robot performs loading and unloading operations, it often needs to rotate its picking end to be perpendicular to the material. However, the aforementioned loading system does not have a limit device for the horizontal rotation of the six-axis robot. This makes it easy for the six-axis robot to rotate out of the safe zone during lateral rotation due to control accuracy and operational errors. Especially in the case of stacked or side-by-side materials, the six-axis robot may collide with surrounding shelves and materials due to excessive rotation, posing a serious safety hazard. Therefore, a material handling unit that can solve the above problems is proposed. Utility Model Content

[0010] This utility model discloses a material transport unit in which the shelf is long and is arranged along the length of a straight slide rail.
