Laser welding control equipment integrating bus stepping drive and control

Abstract

The invention discloses laser welding control equipment integrating bus stepping drive and control. According to the equipment, a driver and a controller are installed in a shell and can be connected with a relay, a contactor and a plurality of stepping motors, an EtherCAT bus communication protocol is adopted between the driver and the controller, and a laser control module and an IO input and output module are arranged on the controller. According to the bus stepping drive and control integrated laser welding control equipment, the welding controller and the motor driver are integrated into a whole and connected with other equipment in a welding mechanism, the communication speed is high, external wiring is reduced, and the use cost is reduced. And the anti-interference capability and the stability of the equipment are greatly improved.

Description

technical field [0001] The invention relates to the field of laser welding equipment, in particular to a laser welding control equipment integrating bus stepping drive and control. Background technique [0002] At present, laser welding technology is emerging as a mainstream welding technology, which has a tendency to gradually replace welding technologies such as electric soldering irons. However, the disadvantage of laser welding technology compared with the previous welding technology is that special laser welding equipment is rarely seen at present, and they all use multiple related equipment, such as PCs, numerical control cards, stepping motors, relays, valves and A laser welding mechanism composed of interconnected devices such as laser emitting heads. In this type of laser welding mechanism, a distributed control method of one laser welding controller plus multiple servo drivers is generally adopted. Each device is generally installed independently and connected to ...

However, the disadvantage of laser welding technology compared with the previous welding technology is that special laser welding equipment is rarely seen at present, and they all use multiple related equipment, such as PCs, numerical control cards, stepping motors, relays, valves and The laser welding mechanism composed of interconnection of laser emitting head and other equipment

In this type of laser welding mechanism, a distributed control method of one laser welding controller plus multiple servo drivers is generally adopted. Each device is generally installed independently and connected to each other through cables to form a network in distribution. The degree of integration is low, it occupies a large area, and there are many and complicated lines, which not only increases the cost of the equipment, but also is inconvenient to install and disassemble, and is also easily disturbed by the external environment, which affects the welding work.
