Station five mainly realizes 601 headrest tube assemblies, 602 sidewall assemblies, welding assembly between 603 connecting plates and 604 connecting rods.After needing the workpiece of welding to be in place this station described, start the fixture of this station, 606 cylinder ventilations, 607 clamping heads, by Workpiece clamping, then start 13 arc welding robots three and carry out welding action according to the motion flow that pilot teaching is good.
The welding of station five is mainly completed part and turns by station six, and station five has welded part another side needs the place of repair welding to carry out repair welding.
Station seven is suspenders, and be mainly used for that the welding of station six is completed part and hang up, the employee being convenient to this station checks welding quality, if there is situation as underproof in solder skip, burn-through or weldquality, then weldment is defective, scraps; If welding quality is qualified, then sends into station eight and carry out follow-up motion flow.
Whether qualified station eight, for detecting station, mainly detect the seat angle adjustor be welded.901 backrests are put after to the suitable position of station eight fixture, then 904 buttons are pressed, start this station clamp, then 902 cylinder ventilations, recliner installing plate place, backrest both sides is clamped fixing, and then this station tester holds backrest top center position, and the bearing between the recliner installing plate that backrest is fixed around both sides rotates 15 degree clockwise and counterclockwise respectively, if rotate smooth and easy, then seat angle adjustor installation qualification.
Station nine mainly realizes the Auto-mounting of motor.Figure 10 is the axonometric drawing of station nine fixture, and code name wherein represents respectively: 1001 buttons, 1002 cylinders, 1003 suspenders, 1004 display screens, and 1005 tighten rifle switch board, 1006PLC switch board, 1007 three linked pieces, and 1008 valves are led, 1009 bearings.Put after part completes, start 1001 buttons, 1002 cylinders ventilation clamping work pieces, continue to put motor to suitable position, 1003 suspenders are used for suspension and tighten rifle, and 1004 display screens can show the moment of torsion tightening rifle in real time, when the moment of torsion tightening rifle reaches setting value, action of tightening up a screw stops.1005 for tightening rifle switch board, can set the upper torque limit value of tightening rifle.1006 is PLC control cabinet.1007 three linked pieces can be evolved to the gas in gas circuit, to improve the service life of cylinder.The air pressure of the 1002 cylinder ventilations controlled on fixture led by 1008 valves.1009 bearings for supporting the fixture of this station, and drive fixture to rotate, and handled easily person carries out upper and lower pieces operation, increases work efficiency.
Whether the motor that station ten is installed mainly for detection of station nine is qualified.Figure 11 is the axonometric drawing of station ten fixture, and code name is wherein expressed as: 1101 hooks, 1102 buttons, 1103 display screens, 1104 controllers.The part that completes of station nine is hung after to 1101 hooks, starts 1102 buttons, 1103 display screens can show in real time the operating condition of mounted motor.1104 controllers are the master controller of mounted motor and station ten power supply.
Robot workstation forms primarily of fixture, welding robot fence and relevant auxiliary device, Figure 12 is the axonometric drawing at 15 robots work one station, code name is wherein: 1201 welding wire copper, 1202 work station switch boards, 1203 transformers, 1204 positioners, 1205 rolling screen door, 1206 fences, 1207 arc welding robots.Outside robot workstation one also comprise station two, station three.
Robot workstation two is similar to the structure of robot workstation one, and the soldering cramping apparatus unlike this work station is made up of the soldering cramping apparatus of station five and station six, and arc welding robot coordinates the frock clamp of this work station to complete pre-set welding action.
In whole piece motor vehicle seat back automatic welding production line, station one needs an operator to perform part and press-in action, and because the operating efficiency of this station is higher, can be mass, then this operator continues the action of control machine workstation one; Station four and robot workstation two can control predetermined production task by an operator; Station seven, station eight, station nine and station ten due to amount of action less, the production task of setting can have been controlled by an operator.Therefore whole piece motor vehicle seat back automatic welding production line can control whole welding production tasks by three operators.As the production capacity of certain production link need be improved, fixture or the robot quantity of corresponding station only need be increased; Or directly increase the quantity of whole production line to improve production capacity.
Be only the preferred embodiment of patent of the present invention in sum, it is not used for limiting the practical range of patent of the present invention, and the change of all equivalences done according to patent of the present invention or modification, all should be considered as the technology category of patent of invention.
