The besmear outfit workshop that Wilhelm Karmann company builds introduces robot welding line sealed craft, welding line is sealed exercise strides automation age very quickly from artificial times, 90% welding line are sealed the operation can be finished by the robot, automation degree is achieved 98% , visual system also can be handled neatly respectively, production is flexible promote with in pairs of finished product quality. The Wilhelm Karmann company that Lv of cloth of abstruse Si Na restrains total position Yu Deguo devotes oneself to roof system to reach all the time truckload develop and make of the system, already had history of more than 100 years up to now. As all-around the car serves a supplier, karmann company contributes brand-new originality, plan, product to reach production system ceaselessly to global automobile industry, offer in-house experiment and content to shed a service at the same time, form all-around service system. Spring 2005, this company finished new besmear smoothly to hold a workshop the 3rd period reach last first phase project, total cost is made an appointment with 1.

2.5 billion euro, it is the project of the biggest odd pen investment since the company holds water. This company builds exceed modern cathode dip to besmear (KTL) workshop year besmear outfit car can amount to 100 thousand or so, technology of uses RoDip besmear outfit is had very tall flexible change rate, can planting indefinitely expression of choice of the random in coating color, can produce the model of much home manufacturer at the same time even. This besmear holds a workshop not only but spray already the model of stop production, still can be opposite already the car of spray paint undertakes weighing gush. Gao Rou sex and efficient Gao Rou sex and efficient it is the advanced welding line that Karmann company builds the two big important characteristics of sealed area, the pure manual and sealed mode of operation previously already upgraded to be versed in for robot automation now art. Sealed line assumes this welding line two manufacturers the manufacturing task of 4 kinds of models, open car of the A4 Cabriolet open car that includes Ao Di, Mercedes-Benz CLK Cabriolet, Chrysler Crossfire reachs Chrysler Crossfire Roadster. The welding line of these models is sealed use plastic collosol of two kinds of PVC. The welding line of space of automobile body interior, floor and automobile body motherboard is sealed all finish in the 3 robots workstation that in ABB robot the ministry designs installation. Seal the flexible, fast sex of glue spray process and economy to keep secret truly, the DispensePac spray system of ABB standard (the system of form a complete set of robot PVC spray) compositive A/B of new-style double passageway changes glue implement, the different model that can come up and down according to product line, the PVC with successful corresponding switch is plastic sol. A/B changes glue implement install the spray gun in robot the upper arm lower part. Change glue implement input end sets 4, agent of two kinds of glue is set into makings mouth and circumfluence mouth respectively; Output end receives two tube, direct spray gun. A powerful person that change glue relies on pressure action to leave shut, can undertake successive processing to plastic collosol of two kinds of PVC. Another characteristic of this kind of solution is, in spray agent of a kind of glue while, can reclaim circularly agent of another kind of glue, fell the material loss when changeover thereby lowermost limit. This kind of solution is an innovation of ABB robot ministry. The SPA 400 spray gun to ABB made this project change one's costume or dress, make it can be handled with spray agent of two kinds of glue. Whole project arrives from the plan executive time is very close, new system entered state of full scale operation after company off end 2005, because plan is driven closely, this covers a system from put into production at the beginning can the automobile body that to the assembly from the back link exactly the amount supplies place to need. At present this product line produces hourly 22 automobile body, 97% what achieved plan utilization rate. After automobile body is outputted from downstair pretreatment KTL area, edge product line passes the first station namely welding line is sealed and artificial preparative area. First workstation that enters next is comprised by robot of industry of axis of two IRB 4400 6. Two stage robots are arranged along automation line around, use advection craft to carry out welding line to engine cabin, passenger cabin and boot sealed. After automobile body enters robot workstation, the system reads the data carrier that takes solid to go up on tray conveyer belt, try to identify to the model. What read extraction data to include glue agent type and welding line place. Even if same model, because engine version and target market are different, the welding line that needs processing is endless also and same. Reading while access is occupied, visual system measures automobile body the exact position inside workstation. After workstation controls a system to obtain data from S4Cplus robot controller, start sealed operation namely. Workstation of the first robot sets artificial processing area, this work area is in charge of transferring to soldering Duan Jin goes finishing, the part interest that cannot touch to the robot dogs with optical welding line craft undertakes sealed, purify is redundant material, and ram is sound-absorbing mat. Before entering workstation of the 2nd robot, should serve automobile body first wear deferent device high. Next motherboard classics are artificial after block Fu, automobile body is immigrant workstation. 4 IRB 2400 robots that install along two flow axes respectively use advection craft to undertake to motherboard welding line sealed. In workstation of the 3rd robot, additionally robot of two IRB 2400 uses the craft that do not have gas to carry out next motherboard sealed. Next, automobile body reentrance an artificial operation area, fu of executive purify block, qualitative accuse and clear working procedure. Wait to send solidify furnace finally. Automobile body from be on welding line till sealed line enters solidify furnace, whole process needs 2h about. The design cycle time of robot workstation is 2min respectively. Reduce artificial workload to be in all models, the weld zone territory of open car of Ao Di A4 Cabriolet is the oldest, its solder length achieves 70m left and right sides. Before this, the robot of sealed to welding line domain is without factory of gram of Lv of cloth of abstruse Si Na experience. ABB robot ministry employed the solution of innovation here, on the robot cloth set cop of two glue agent, realized the switch control of glue agent successfully. The quality with sealed welding line had gotten the affirmation of the manufacturer. In ensure the premise of standard of high level quality falls, automation degree also went up a new chance to extricateoneself from an awkward position. The welding line of ABB robot can reach a gender very conspicuous. Crossfire model realizes the Kelaisile that compliance of ABB robot department measures to high yield the welding line of 90% can reach a gender, the level of outclass competitor. Inside the range that the technology can reach, sealed automation degree already obtained welding line at present 98% , ABB robot ministry is in this one domain not only outstanding, still achieved expectant manufacturing rate. In welding line sealed craft domain, ABB robot ministry cashed in the round at the outset acceptance. CNC Milling
