Abstract
An end effector attachment apparatus is an apparatus to be attached to an end effector of a robot. The end effector attachment apparatus includes a base plate, a mount plate on which the end effector is mounted, an attraction mechanism for attracting the mount plate to the base plate, and a bellows coupling the mount plate to the base plate. The front and rear edges of the bellows are sealed to the base plate and the mount plate to secure a sealed space inside the bellows.
Claims6
An end effector attachment apparatus to be attached to an end effector of a robot, comprising:
- a base plate;
- a mount plate on which the end effector is mounted;
- an attraction mechanism for attracting the mount plate to the base plate, wherein the attraction mechanism comprises a magnet;
- a bellows coupling the mount plate to the base plate;
- and
- a misalignment detection unit for detecting that the mount plate misaligns from a predetermined position relative to the base plate,
- wherein the misalignment detection unit comprises contact sensors,
- wherein front and rear edges of the bellows are sealed to the base plate and the mount plate so as to secure a sealed space inside the bellows,
- when the misalignment detection unit detects that the mount plate misaligns from the predetermined position relative to the base plate, an attracted state where the mount plate is attracted to the base plate by the attraction mechanism is released, and the inside of the bellows is pressurized to extend the bellows and separate the mount plate from the mount plate, and
- the inside of the bellows is depressurized to contract the extended bellows and return the separated mount plate to the predetermined position, and the attracted state where the mount plate is attracted to the base plate by the attraction mechanism is returned to fix the mount plate at the predetermined position.
An end effector attachment apparatus to be attached to an end effector of a robot, comprising:
- a base plate;
- a mount plate on which the end effector is mounted;
- a wire member for suspending the mount plate from the base plate;
- a winding device for feeding and winding the wire member, wherein the winding device comprises a reel;
- and
- a misalignment detection unit for detecting that the mount plate misaligns from a predetermined position relative to the base plate,
- wherein the misalignment detection unit comprises contact sensors,
- wherein when the misalignment detection unit detects that the mount plate misaligns from the predetermined position relative to the base plate, the winding device feeds the wire member to separate the mount plate from the base plate, and the winding device winds the wire member to return the mount plate to the predetermined position.
