Highly viscous material coating apparatus

A highly-viscous material coating apparatus mounted on a unit comprising means for supplying the highly-viscous material to said coating apparatus and a robot having a robot arm for supporting and manipulating said coating apparatus, said coating apparatus comprising:

• a base plate fixed on said robot arm of said robot;
• a gun body having a highly-viscous material supply port, a nozzle shaft and a nozzle disposed at an end of said nozzle shaft, said nozzle being in fluid communication with said supply port;
• pivoting means for pivotally mounting said gun body on said base plate for pivotal motion about an axis substantially transverse to the length of said nozzle shaft and in a plane with respect to said base plate;
• a pivotable plate fixed on said pivoting means and comprising means such that a pivotal motion of said pivotable plate will cause said gun body to pivot in said plane;
• at least one compression spring for biasing said pivotable plate;
• and
• means fixed on said base plate for at least partially restricting, selectively, the pivoting of said gun body.

A highly-viscous material coating apparatus adapted to be mounted on a unit for supplying the highly-viscous material to said apparatus and for supporting said apparatus, said apparatus comprising:

• a base plate fixed on said unit;
• a gun body having a highly-viscous material supply port, a nozzle shaft and a nozzle disposed at an end of said nozzle shaft, said nozzle being in fluid communication with said supply port;
• pivoting means for pivotally mounting said gun body on said base plate for pivotal motion in a plane with respect to said base plate;
• a pivotable plate fixed on said pivoting means and comprising means such that a pivotal motion of said pivotable plate will cause said gun body to pivot in said plane;
• at least one compressing spring for biasing said pivotable plate;
• means fixed on said base plate for at least partially restricting, selectively, the pivoting of said gun body;
• and
• a linear motion bearing, said nozzle shaft being slidingly received in said linear motion bearing, further comprising a spline and spline groove for preventing relative rotation of said nozzle shaft and said linear motion bearing.
