Abstract

A vacuum tool operable to assemble a sheet steel bonding clip over the edge of a receiving component has a specially designed working surface profile to impart required linear and rotational movement to the clip as it is pushed over the component edge during one straight line movement of the tool. Fig. 1 shows a portion of a tool 1 having a chamfered working surface 2 formed at an angle of about 45 degrees to the longitudinal axis of the tool. A recess 3, quadrant-shaped in section, is provided at one end of the chamfered surface. The working surface of the tool is connected to a vacuum source (not shown) by means of a longitudinal bore 4, and the surface itself is provided with a rectangular vacuum seal 5 suitably dimensioned to suit the size and shape of the clips to be assembled.

Tool for Robotic Assembly of Bonding Clips

A vacuum tool operable to assemble a sheet steel bonding clip over the edge of a receiving component has a specially designed working surface profile to impart required linear and rotational movement to the clip as it is pushed over the component edge during one straight line movement of the tool. Fig. 1 shows a portion of a tool 1 having a chamfered working surface 2 formed at an angle of about 45 degrees to the longitudinal axis of the tool. A recess 3, quadrant- shaped in section, is provided at one end of the chamfered surface. The working surface of the tool is connected to a vacuum source (not shown) by means of a longitudinal bore 4, and the surface itself is provided with a rectangular vacuum seal 5 suitably dimensioned to suit the size and shape of the clips to be assembled. In use, the tool is lowered onto each individual clip 6 in turn, and by means of the applied vacuum lifts it from its feeder rail 7 in the direction of arrow
8. The tool and clip are moved into position vertically above the component edge 9, as shown in Fig. 2. The tool is accurately positioned so that there is a small offset x between the spring portion 10 of the clip and the receiving component edge. A vertical downward movement of the tool, as indicated by the arrow 11, brings the angled face of the clip into contact with the component edge. Further downward movement causes a small lateral shift, provided by compliance in the robot arm (n...
