Description

Technical Field

[0001] The utility model relates to a highly efficient and stable wood grabber, belonging to the technical field of wood materials. Background Art

[0002] Wood materials play a huge role in the fields of construction, furniture, packaging, railways, etc. Compared with other materials, wood has unique properties such as porosity, anisotropy, swelling and shrinkage, flammability and biodegradability. How to better utilize these properties and minimize their side effects is the main problem that wood scientists and engineering and technical experts have been working hard to solve for a long time. Foresters are also actively involved in wood science research, understanding and improving the basic properties of wood from the perspective of tree genetics. Wood materials are mainly divided into wood boards, wood profiles, wood wires, wood sheets, bamboo products and other categories.

[0003] A Chinese patent publication (publication number: CN 219546085 U) discloses a wood grabbing machine grasping structure, including a mechanical arm, a support plate is fixedly arranged on the output end of the mechanical arm, a plurality of brackets are fixedly arranged on the support plate, and a rotating shaft is rotatably arranged on the plurality of brackets, and a first clamping arm is rotatably arranged on the rotating shaft, two long plates are fixedly arranged on the first clamping arm, and a plurality of limit plates are fixedly arranged on the long plates and the support plate, and a cylinder 1 is rotatably arranged on the limit plate, a shaft body is rotatably arranged on the top end of the first clamping arm, and a second clamping arm is rotatably arranged on the shaft body, and a cylinder 2 is rotatably arranged between the second clamping arm and the first clamping arm, and by means of the first clamping arm arranged on the support plate and the second clamping arm rotatably arranged on the first clamping arm, it is achieved that when the device is used, the opening and closing angles of the clamping arm can be controlled by the cylinder 1 and the cylinder 2 to ensure the clamping of the wood when facing different numbers of wood;

[0004] Although the above patent can control the opening and closing angles of cylinders one and two to ensure the clamping of the wood when facing different quantities of wood, it still has certain defects. In the process of wood processing, due to the heavy weight of wood, a robotic arm is usually required to grab the wood. The position of the robotic arm in the above patent may be inconvenient to adjust. There may be multiple workstations in the process of wood processing. In this way, each robotic arm only corresponds to one workstation during use, thereby limiting the scope of use of the robotic arm. Multiple workstations require multiple robotic arms.
