Apparatus for testing adhesion of an adhesive tape to a bonding surface under a load applied to the tape

摘要

Apparatus for testing adhesion of an adhesive tape to a bonding surface under an applied load includes a test surface of a predetermined configuration to which a test tape may be adhered, a clamping device for grasping a free edge of the test tape, a guide for constraining the clamping device to move linearly relative to the test surface, and an actuator arrangement for driving the clamping device along the guide at a selected speed and with a selected force to apply the force to the test tape. The actuator arrangement includes a first and second linear actuators operable to generate differing ranges of force values, a motor for driving the linear actuators, and a selector arrangement for connecting the motor alternately to the first and second linear actuators according to the selected force to be applied.

1. Apparatus for testing adhesion of an adhesive tape to a bonding surface under a load applied to the tape, the apparatus comprising:
(a) a test surface to which is adhered a length of adhesive tape to be tested, (b) a clamping device for grasping a free edge of the adhesive tape to be tested, (c) a guide for constraining the clamping device to move in a defined linear direction relative to the test surface, and (d) an actuator arrangement for driving the clamping device along the guide at a selected speed and with a selected force to apply the force to the tape adhered to the test surface, the actuator arrangement including:
(i) a first linear actuator arrangement operable to generate the selected force within a first range of force values,(ii) a second linear actuator arrangement operable to generate the selected force within a second range of force values,(iii) a motor for driving the linear actuators arrangements, and(iv) a first selector arrangement for selectively connecting the motor alternately to the first and second actuator arrangements according to the selected force to be applied to the clamping device.
