Module for automatic tool exchange device

An automatic tool exchange device having a first coupling member configured to attach to one of a robot main body side and a tool side and a second coupling member configured to attach to the other one of the robot main body side and the tool side, the first and second coupling members configured for detachable coupling to each other, the device having a module comprising:

• a first module detachably attached to the first coupling member;
• and
• a second module detachably attached to the second coupling member, for transmitting electrical signals between the first coupling member and the second coupling member by permitting transmission of electrical signals between the first module and the second module,
• wherein the first and second modules each have a coil unit including a coil head and an electromagnetic shielding member, wherein the coil heads comprise a core member in combination with a coil member, a transmission surface including a magnetic path open surface being formed by the core member, the electromagnetic shielding member arranged on an outer circumference of the core member exclusive of the transmission surface, the coil head further including a gap member being interposed between the core member and the electromagnetic shielding member, the gap member having a lower electromagnetic shielding effect than the electromagnetic shielding member, wherein the transmission surfaces of the core members face opposite each other to define an opposite facing type interface for performing transmission of electrical signals using an electromagnetic induction effect, and one of the coil units on the opposite facing type interface is attached to the first module and another one of the coil units is attached to the second module such that the first module and the second module are configured to permit transmission of electrical signals therebetween.
