During the body‑in‑white assembly of a passenger car, the red side‑mounted suction cup with bellows is used to hold large sheet‑metal panels in place while robotic welders and spot‑weld guns work around the edges. The flexible bellows allow the cup to accommodate the slight curvature of the panel and to maintain suction even when the robot arm moves the part into the welding cell. By attaching the cup to the side of the work‑holding fixture, the system can lift, rotate, and precisely align doors, hoods, and roof sections without the need for additional clamps, reducing change‑over time and preventing surface damage. The suction cup also serves as a quick‑release point for automated transfer stations, letting the same robot pick up a panel, move it to a stamping press, and return it to the same fixture for final assembly. In machine‑tool manufacturing, a similar cup can secure heavy casting blanks on a CNC milling table, allowing rapid repositioning between machining steps.
