Abstract

A robotic two-component epoxy mixing and dispensing scheme is described for the application of small batch quantities of high viscosity epoxy. This process will be used on a robotic automated assembly process for printed circuit armature construction. The robot will be supplied with syringes with preattached needles. Each syringe will contain 4 through 6 steel balls to be used for mixing (inserted by the operators at time of loading). The diameter of these balls will be approximately one-fifth through one-third the inside diameter of the syringe. The plungers for the syringes are provided separately. The epoxy used is highly viscous. One component is a paste (approximately 500,000 centipoise). The other component is liquid (approximately 2000 centipoise).

Automatic Epoxy Mixing Tool

A robotic two-component epoxy mixing and dispensing scheme is described for the application of small batch quantities of high viscosity epoxy. This process will be used on a robotic automated assembly process for printed circuit armature construction. The robot will be supplied with syringes with preattached needles. Each syringe will contain 4 through 6 steel balls to be used for mixing (inserted by the operators at time of loading). The diameter of these balls will be approximately one-fifth through one-third the inside diameter of the syringe. The plungers for the syringes are provided separately. The epoxy used is highly viscous. One component is a paste (approximately 500,000 centipoise). The other component is liquid (approximately 2000 centipoise). These components are supplied to the robot in bulk-dispensing tubes. These tubes are connected to a custom automatic air-dispensing system controlled by the robot. The robot will start the process by fetching a syringe and placing it into a temporary holding fixture. The robot will transport the fixture to a digitally encoded scale which it will use to dispense the appropriate quantity of the two components into the syringe. Once this is accomplished, the robot will install the plunger into the syringe and transport the syringe to the mixing tool. The mixing station consists of a pair of magnets mounted on a DC motor. These magnets are high flux density magnets and are mounted to a st...
