Rotation.
Specifically, driving gear C22 is driven forward or reverse by motor C23, to realize mobile carrier C21 to welding section
Domain is mobile or removes from welding region.
Meanwhile mobile unit C2 is destroyed in order to prevent, being additionally provided on track frame A2 in the application can be with movement
The shield C24 of carrier C21 movement and relative telescopic setting.
In this example, above-mentioned full-automatic duplex spot welder further includes the reclaimer robot D of automobile tray Full-automatic welding, is used
It successively feeding and is placed in positioning unit C1 in the panel for constituting two automobile tray,
As shown in Figures 4 and 5, reclaimer robot D includes the connection frame D1 being connected with robot arm, is arranged on connection frame D1
Adsorbent equipment D2, wherein adsorbent equipment D2 include adsorption head D20 on the connection frame D1, drive adsorption head D20 draw or
The actuator D21 of automobile tray panel is discharged, reclaimer robot D further includes the first folder being arranged on connection frame D1 in cross
Arm D3 and the second clamp arm D4, the positioning collet D5 that the first both ends clamp arm D3 are set, the both ends that the second clamp arm D4 is set
And the wedging collet D6 that can be wedged from the overlapping portion between two-layer panel, wherein positioning collet D5 is for after limiting panel feeding
Displacement；Collet D6 is wedged along the length direction relative motion of the second clamp arm D4.
Specifically, wedging collet D6 includes the Gripper body 60 for being formed with end bayonet 60a, medial end portions bayonet 60a's
Entrance is set towards the side of panel, the bottom of Gripper body 60 from the end of open-ended 60a to 60 inner inclination of Gripper body
It sets.Convenient for wedging from overlapping portion, while when the separation of two pieces of panels, the displacement of panel will not be caused.
Further, the height of end bayonet 60a is equal with the thickness of panel x.Limitation panel x teetertotter can
Can, while also further decreasing adsorption capacity provided by adsorption head D20.
Reclaimer robot further includes the push rod D7 being arranged on the second clamp arm D4, is used for driving push rod D7 along the second clamp arm
The telescopic rod D8 of D4 length direction movement, wherein end of the push rod D7 far from telescopic rod D8 is connected with wedging collet D6.
Preferably, push rod D7 is located at the top of the second clamp arm D4, is equipped with guide and limit seat D9 in the end of the second clamp arm D4,
Wherein push rod D7 passes through guide and limit seat D9 and is connected with wedging collet D6, and when panel x clamping, wedging collet D6, which is resisted against, to be led
To the outer end of limit base D9.The relatively fixed of position is realized, so that more steady during panel transfer.

Meanwhile in this example the driving method of telescopic rod D8 be it is pneumatic, it is identical as actuator D21 in this way, be pneumatic control.
Therefore, it using above-mentioned reclaimer robot D, has the advantage that
1. by the setting of templin chuck, be convenient for two panels panel relative separation, at the same after ensuring to separate panel to be drawn it is accurate
Stacking；
2, on the one hand the setting of positioning collet can limit the opposite of below the panel panel to be drawn when panel is drawn and separated
Displacement；On the other hand in panel moving process, the offset or deflection of panel are limited.
To sum up, the implementation process of this implementation is as follows:
By reclaimer robot D, one piece of panel x is first taken, is placed in lower die 1, wherein the positioning pin 2 of lower die 1 is from panel two sides
Positioning is pierced by, and then takes another piece of panel x again, and the positioning of second piece of panel is also passed through by the positioning pin for first piece of panel of emerging
The folded setting position of two pieces of panel x is realized in hole, and lower die 1 is then transferred (moving along y-axis to crossing center) at upper mold 3, when
When lower die 1 is in the underface of upper mold 3, upper mold 3, which moves downward, to be molded, then by locking mechanism 5 by upper mold 3 and lower die 1
It locks relatively, and is sent into spot welding region, then moving synchronously by two welding gun component B in x-axis, and in the work of double welding gun
Under, the spot welding of automobile tray upper surface each welding position of bottom surface is fast implemented, after the completion of to be welded, lower die is removed and is welded
Region, locking mechanism unlock, and hooks upper mold under hanging hook assembly upwards, realizes the separation of upper mold and lower die, then will under
Mould and the automobile tray being welded remove outside bonding machine, and the feeding of automobile tray can be realized.
At the same time, while lower die removes welding region, another group of feed device C also repeats that above-mentioned panel is folded to be set
Position fixing process, and after being molded by upper and lower mould, automobile support of the previous group feed device C by postwelding is waited until in the region
When disk removes spot welding region, the automobile tray having good positioning is sent into spot welding region by this group of feed device, so that realizing can continuity
