Description

Technical Field

[0001] This utility model relates to the field of mechanical rigid arm technology, specifically a rigid arm and pneumatic lifting device that can be operated from multiple angles. Background Technology

[0002] A rigid robotic arm (also known as a rigid-arm assisted manipulator) is an industrial material handling device with a rigid arm as its main structure. It uses a pneumatic or electric control system to grasp, move, and precisely position heavy objects. Its core components include: a rigid frame made of high-rigidity steel or aluminum alloy to ensure load stability; a pneumatic / electric drive system that achieves dynamic load balance through logic-based pneumatic control or gravity sensing; and a joint module equipped with a rotating axis and braking device to support multi-dimensional movement and hovering.

[0003] For example, a Chinese patent discloses a rigid-arm robotic hand, publication (announcement) number: CN210998786U, which includes a base, a column at the middle position of the top of the base, a connecting rod at the top of one side of the column, a first connecting plate at one side of the top of the connecting rod, a rotating shaft at the bottom of the first connecting plate away from the connecting rod, and a second connecting plate at the middle position of the rotating shaft away from the first connecting plate. This rigid-arm robotic arm uses a first motor, a bidirectional threaded rod, an internal threaded sleeve, and gripping claws to clamp items, facilitating item handling, saving labor costs, and improving handling efficiency. Simultaneously, a second motor, gripping chamber, and suction cups work together to adsorb items, increasing the variety of items the robotic arm can handle. This allows the robotic arm to handle some deformable or large items. While the patented design facilitates item handling, saves labor costs, and improves efficiency, it does not allow for multi-angle operation. This prevents the pneumatic lifting device from lifting items at other angles, hindering user convenience and affecting normal operation. Utility Model Content

The extension mechanism 2, through the lifting device 105, drives the air-inflating lifting device 4 to rotate, adjusting the lifting angle. Then, the air-inflating lifting device 44 is inserted into the lifted item. By increasing the air pressure inside the air-inflating lifting device 44, the lifting device pulling plate 45 is pushed outward to insert into the slot inside the item. After completion, the lifting device 105 is driven, and the lifting device 105 lifts the item through the air-inflating lifting device 4.

[0041] In summary, this multi-angle controllable rigid boom and pneumatic lifting device, through the multi-angle control mechanism 3, can control the rotation of the pneumatic lifting device 44, causing it to rotate around the rotating disk 35 as the center. By adjusting the angle of the pneumatic lifting device 44, the rigid boom and pneumatic lifting device can be angle-controlled. When using the rigid boom, the pneumatic lifting device can lift items at other angles, making it convenient for users and ensuring normal use.
