Axle installing hole, vertical and parallel be provided with multiple impeller-hub 48 on drive link 45, each impeller-hub 48 inserts the second rotation of correspondence
In the axle installing hole of arm 44.Drive link 45 horizontal movement under cylinder 46 acts on.
In the present invention, the operation principle of non-solder area protection mechanism is as follows: welding gun is when welding, by body structure
Impact, being partially welded will necessarily occur in some positions, the least bit and rosin joint have influence on non-solder region, and main cause is to grasp in welding process
Making personnel cannot the position of visual solder joint.
When non-solder of the present invention area protection mechanism cylinder 46 works, to the thrust of drive link 45 horizontal direction, drive link
45 drive impeller-hub 48 also to do the movement of horizontal direction, and first rotating arm 42 and the second turning arm 44 are in impeller-hub 48 and connecting shaft
Rotate around connecting shaft 43 under 43 styles of work.During rotation, protective baffle plate 41 is positioned at vertical height and sends out the most accordingly
Changing, thus for the non-solder region of differing heights, can be by under cylinder action so that protective baffle plate 41 hides
Gear, thus can be greatly reduced occur being partially welded, the least bit and rosin joint situation, also well protection to non-solder region.Anti-bib
Plate 41 size is interchangeable to adapt to the non-solder region of different areas.Owing to many automobile same area carry out same
Time welding, it is possible to use multiple protective baffle plate 41.
As shown in Figure 6, the middle welding controller control method of robot of the present invention intermediate frequency resistance welding switch board is as follows: logical
