Abstract

The invention discloses a white roof panel laser soldering process control device. The process control device comprises a welding robot, a laser device, a welding head, a power meter and a process control cabinet, the process control cabinet comprises a programmable logic controller (PLC), the PLC is respectively connected with a remote control cabinet, the welding robot, the welding head and the laser device through a devicenet bus to transmit a control signal and perform data exchange, the power meter is connected with the PLC to transmit measured power to the PLC through analog quantity input / output (I / O) conversion, and the PLC is connected with an input displayer through an Ethernet to be used for setting process parameters, device control and device condition monitoring. According to the white roof panel laser soldering process control device, control functions in the white roof panel laser soldering production line of cars can be integrated, the welding quality and device stability are guaranteed, and simultaneously functions of fault display, fault warning and fault shutdown are achieved.

Description

technical field [0001] The invention relates to a laser brazing process control device for the top cover of an automobile body in white, in particular to a process control device for a laser brazing production line for the top cover of an automobile body in white. Background technique [0002] The annual production of cars in China has reached 20 million. Taking the plastic-based roof trim as an example, the cost price of each car is more than 50 yuan per car, so the annual manufacturing cost is at least 1 billion yuan. The aluminum-based decorative strips of some high-end cars cost about 180 yuan per bicycle. The use of laser brazing for roof welding only requires the cost of welding wire, water, gas and electricity. In addition to the initial investment in equipment, the later use and maintenance costs are very low. The application of laser brazing production line for automobile body-in-white roof cover in automobile OEMs is showing more and more trends. [0003] There a...
