Our E-frame is based on the Automotive Cell idea but with bigger stations and a track for the robot.
The robot is placed on a track. This track is build on our E-frame. In this frame we have 2 stations in line, each with an external axis positioner.
The big advantages of this concept are:
- Monobloc philosophy remains: known advantages of movable aspect etc (same as H-frame)
- Ergonomically and safer programming: you can program in front of the robot and the jig, and not between the robot and the jig; also note that the Ferris Wheel often implicates a higher axe position on the robot side (= program side), so extra platforms or ladders are needed!
- No mechanical influence between the 2 working stations: known problem with the Ferris Wheel if you have different loads on both sides or you pull to hard on one side while the robot is welding on the other side. With a PanaDice 500 and CB you have 1.000 kg capacity on each station.
- Because of the integrated track, we can use even with a smaller robot the maximum reach on the complete jig length, so the accessibility to the (complex) jig is optimal.
- Better reach ability close to the robot (using the track you can pull away the robot).
- Walking distance for the operator is identical as a ferrish wheel, HOWEVER now there is space, when you weld 2 different products, to put the components (unwelded + welded) in front of the working zones. This is a big disadvantage of the ferrish wheel and the manipulator with rotating table where often there is not enough place for this.
- Operator can be present just in front of the jig before the doors open. Optimal using of time. This is not possible with ferrish wheel systems.
- You can continue on one station while you do maintenance on the second jig. This is not possible with a ferrish wheel system. Important for high volume automotive applications.
- Dimensions of parts and jig is less important:no ferrish wheel construction as an obstacle. Better reach ability of the robot thanks to the track.
- In going from one to another jig, this jig can rotate when the robot moves to this jig. This is not possible with ferrish wheel (risk of collision with the ferrish wheel construction)
- Not the main goal, but you can extend the system at the back side with more stations (for example pre-welding of interiors)
