Abstract

The co-axial vacuum insertion head is capable of picking and placing a variety of module sizes (12 mm, 25 mm, 28mm, and 36 mm) on a printed circuit board without damaging the modules in doing so. This head allows the insertion of modules in an area that is "brick-walled" (a module position that can be completely surrounded by adjacent modules which preclude the use of a jaw-type placement head). This head has the capability of radially orienting a module in any of four 90-degree positions and of detecting bent pins prior to plugging the module into a board. The insertion head is attached to the Z-arm of the IBM 7565 robot; therefore, part of the insertion cycle is carried out by the robot. When the outer head 6 is in the downmost position, the 25 mm, 28 mm and 36 mm modules can be picked up and inserted.

Co-Axial Vacuum Insertion Head for Use on Computer-Controlled Module Insertion Machine

The co-axial vacuum insertion head is capable of picking and placing a variety of module sizes (12 mm, 25 mm, 28mm, and 36 mm) on a printed circuit board without damaging the modules in doing so. This head allows the insertion of modules in an area that is "brick-walled" (a module position that can be completely surrounded by adjacent modules which preclude the use of a jaw- type placement head). This head has the capability of radially orienting a module in any of four 90-degree positions and of detecting bent pins prior to plugging the module into a board. The insertion head is attached to the Z-arm of the IBM 7565 robot; therefore, part of the insertion cycle is carried out by the robot. When the outer head 6 is in the downmost position, the 25 mm, 28 mm and 36 mm modules can be picked up and inserted. When the outer head 6 is in the topmost position, the 12 mm stack and planar modules can be picked up and inserted. The outer head 6 is pushed to the upward position by the stepped block 16 while picking up 12 mm modules, as shown in Fig. 1. When picking up larger modules the head is rotated 45OE by motor 9, as shown in Fig. 2. Cylinder 3 is activated to push outer head 6 to the downward position. When the cylinder is retracted, the head is rotated back to zero (home) position against a mechanical stop. The vacuum is monitored by a double detented valve 11 to either draw vacuu...
