A robot production line and control method for large medium and heavy plate workpieces in ships

Abstract

The invention discloses a robot production line for a ship large medium plate workpiece. The robot production line is a conveying system formed by a plurality of conveying belts. A plurality of machining stations are preset on the conveying system, and the machining stations sequentially comprise an assembling station, a robot welding station, a manual repairing station, a back burning station anda carrying station. A conveying device is arranged above the assembling station and the carrying station, and is controlled manually. According to the robot production line for the ship large mediumplate workpiece, the automatic welding of the workpiece is realized through the whole production line, so that the beauty and quality of welding positions are improved, and the welding efficiency is improved meanwhile; the back position welding process of manual welding is reduced through the arrangement of the back burning station, so that the quality is guaranteed, the efficiency is improved, and the loss is reduced through the control over the processes by the stations.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a robot production line and a control method for large medium-thick plate workpieces of ships. Background technique [0002] With the development of the times, around 2010, my country's economic and social development environment has undergone major changes, the increase and decrease of investment and exports have slowed down significantly, and economic development has gradually entered a long-term normal state. Resource and environmental constraints continue to strengthen, and the cost of labor and other production factors continues to rise; the shipping market continues to be depressed, shipbuilding capacity is seriously overcapacitated, ship prices are low, and it is difficult to receive orders. The traditional shipping industry that consumes a lot of social resources is gradually facing the Elimination. Welding is the largest job in shipyards. With the continuous advancem...

Problems solved by technology

Resource and environmental constraints continue to strengthen, and the cost of labor and other production factors continues to rise; the shipping market continues to be depressed, shipbuilding capacity is seriously overcapacitated, ship prices are low, and it is difficult to receive orders. The traditional shipping industry that consumes a lot of social resources is gradually facing the Elimination. Welding is the largest job in shipyards. With the continuous advancement of industrial automation, the automotive industry has already used welding robots instead of manual labor. The quality and appearance of welding robots are much higher than manual welding, while improving Efficiency. In the shipbuilding industry, it is relatively more difficult to realize the welding robot operation of medium and thick plate arc welding in shipbuilding than in the automotive industry. Existing shipyards usually process a large number of scattered workpieces manually in order to process some large plates. And put it on the workbench for manual welding, and finally remove the welding workpiece to proceed with the next welding. Using this method will cause a large welding area, waste of labor, and low production efficiency. At the same time, when welding the back of the workpiece due to the shape of the plate Irregular and large in size, it is inconvenient to turn over and weld, which further affects the production efficiency of the workpiece, so there is an urgent need for a robot production line for large medium and thick plate workpieces in ships to solve the above problems
