Object shelf tray self-adaptation welding device based on laser vision

Abstract

The invention discloses an object shelf tray self-adaptation welding device based on laser vision. The welding device comprises a base, two first axis moving devices arranged on the base in parallel, a second axis moving device arranged perpendicular to the first axis moving devices, a vertical axis moving device arranged on the second axis moving device, a laser vision sensor and a welding gun gesture mechanism. The laser vision sensor and the welding gun gesture mechanism are arranged abreast at the bottom end of the vertical axis moving device. Two ends of the second axis moving device are connected with the first axis moving devices. The laser vision sensor collects a welding gap image and stores the image to a computer through an image collection card, the computer processes the image to obtain the welding gap position, and a motion control card is utilized to control a welding gun walking device to conduct welding accurately. The self-adaptation welding device is high in self adaptability, capable of accurately recognizing the welding gap position of an object shelf tray, high in expandability, low in cost, simple and efficient to control and high in reliability.

Description

[0001] technical field [0002] The invention belongs to the field of automatic welding and relates to a laser vision-based self-adaptive welding system for shelf pallets. [0003] Background technique [0004] Pallet racks are widely used in manufacturing, third-party logistics and distribution centers and other fields. A shelf pallet is often welded by many parts with the same specifications, so the weld seam is the main feature of the pallet shelf. The structure of the pallet shelf determines that the key to its production is welding. The welding efficiency directly determines the production efficiency of the pallet rack, and the welding quality also directly determines the quality of the pallet rack. It can be seen that for pallet racks, the workload of welding is very huge, and the labor intensity of workers is very high. However, the existing technology uses manual semi-automatic welding, and operators need to be engaged in welding work for a long time in a high-temp...
