It is connected with time controller by data line, time controller controls the dwell time T of translation mechanism movement, in T time section
Soldering tip 7 carries out welding, after the completion of the spot welding work of unit one is by time T welding, time controller control translation
Mechanism kinematic, which reruns, to go at second workpiece；There is corresponding light hole 8 at second workpiece, optical signal transmitter 9 is sent out
Signal light out passes through light hole 8 and can be received by optical signal recipient 10；Translation mechanism is connect with photoelectric switching signal, and is passed through
Optoelectronic switch controls the stopping of translation mechanism movement, and translation mechanism movement stops after optical signal recipient 10 receives signal light；
Then the spot welding work of second workpiece is carried out.
For the principle of two degrees of freedom manipulator: pedestal 3 and 4 one end of lower shake-changing arm are controlled by first harmonic motor 11, under
It is controlled between 5 one end of the Rocker arm 4 other end and upper arm by second harmonic motor 12,5 other end of upper arm passes through with 6 one end of small rocker
Third harmonic motor 13 controls, and soldering tip 7 is arranged in 6 other end of small rocker.Pedestal 3, lower shake-changing arm 4, the upper arm 5, small rocker of the present apparatus
6, the rotation between soldering tip 7 is driven by harmonic motor, can only two degrees of freedom in perpendicular rotation.
Translation mechanism is screw-nut transmission mechanism, and screw-nut transmission mechanism includes servo motor, retarder, shaft coupling
Device, drive lead screw 14, driven screw 15, the rotation of servo motor are able to drive the rotation of turn-screw, drive lead screw 14 with from
Dynamic screw 15 is sequentially connected, and the rotation of turn-screw drives driven the moving horizontally along seat rail 1 of screw 15, to pass through movement
The mode of spot welding device realizes side by side spot welding one by one, without separately setting transport mechanism.
In addition, weld cap 16 is arranged far from 5 one end of upper arm in small rocker 6, it is detachably equipped with soldering tip 7 on the weld cap 16, this is just
Suitable soldering tip 7 can be selected to work according to actual welding needs.Sub-material area 17, sub-material are equipped at the top of the seat rail 1
Remove can to prevent work or the useless part and other essential tools etc. of welding.It is additionally provided with the shading being adapted with light hole 8
Plug 18, shading plug 18 can cover light hole 8, can be selected according to the welding of different workpieces between suitable light hole 8
Away from because the distance between two neighboring workpiece can increase for big workpiece, this it is necessary that two neighboring light hole 8 it
Between distance to increase.
