An engaging member, a female member and a tool changer that can be downsized are provided, and the engaging member is an engaging member including: an engaging surface that allows a cam provided in a male member to engage therewith; and a dispersing surface that transmits a force provided from the cam via the engaging surface, to a female member body, wherein the dispersing surface includes a first dispersing surface and a second dispersing surface perpendicular to each other, and a cross-sectional shape perpendicular to a longitudinal direction is formed in a substantially triangular shape by the dispersing surface and the engaging surface.

A slide portion of a first adapter is fitted into a slot of a second adapter, and a ball is disposed between a cam member supported by the slide portion and an opening edge portion constituting the slot. The ball can advance toward or retreat from an engagement groove of the opening edge portion by movement of the cam member. By operating a release button connected integrally with the cam member and also sliding the first adapter and the second adapter relative to each other, the ball retreats, and the first adapter and the second adapter are separated from each other.

A force multiplier (5) configured to assist movement of the operating rod (22) in its axial direction is provided. An engagement recess (52) provided on an outer periphery of the operating rod (22) has a cam surface (52a) configured to make engagement with an engagement ball (51). There is provided a support hole (53) configured to allow movement of the engagement ball (51) in a radial direction of operating rod (22) and to restrict movement of the engagement ball (51) in the axial direction of the operating rod (22). A pressing member (54) configured to press the engagement ball (51) is provided, and the pressing member (54) has a force-multiplying surface (54a).

Devices, systems, and methods for automatically exchanging a first end-effector on a robot arm with a second end-effector housed in a docking station. The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

A hand at a robot arm leading end is provided with a mounting portion for a finger. The mounting portion includes a guiding unit that guides a supported portion of the finger so as to enable the supported portion to pass through from one end part of the guiding unit 31 to another end part thereof. The mounting portion further includes a lock mechanism. The lock mechanism moves the supported portion from any of end parts of the guiding unit 31 toward a mount position between the end parts, to thereby bring the supported portion of the finger into a restricting state at the mount position. Moreover, the lock mechanism moves the supported portion toward any of the end parts from the restricting state, to thereby bring the supported portion from the restricting state into a releasing state.

An inkjet coating machine is provided to prevent the components in the paint from precipitating. The inkjet coating machine includes: a robot arm having a chuck at a front end and a nozzle head unit detachably mounted on the chuck. The nozzle head unit includes a nozzle head having a nozzle for spraying the paint, a nozzle control unit for controlling driving of the nozzle, and a head-side circulation path enabling the paint to circulate within the nozzle head. The nozzle head, the nozzle control unit and the head-side circulation path are integrally configured. The coating machine further includes a standby holding unit that holds at least one nozzle head unit in standby and a head replacement unit that replaces the nozzle head unit.

The first end-effector has a clamp that either engages or disengages the robot arm based upon an application of force of the robot arm onto the end-effector. The clamp has a spring loaded clip that disengages the first end-effector to allow the robot arm to move away from the released first end-effector. The robot arm is configured to automatically move to a port of a docking station housing the desired second end-effector using magnetic coils on the robot arm and the docking station to guide the robot arm.

The system includes a robot interface disposed on a robot arm, and an end effector configured to selectively couple to the robot arm via the robot interface. The end effector includes an upper jaw, a lower jaw, and a pair of arms configured to carry a substrate. The upper jaw and the lower jaw are spaced apart in a first direction and biased together, and the pair of arms are spaced apart in a second direction orthogonal to the first direction. When the end effector is coupled to the robot arm, the robot interface is disposed between the upper jaw and the lower jaw. To exchange the end effector, the upper jaw and the lower jaw can be separated to release the robot interface.

A modular gripper has a body with a trident section and cylindrical section. A powering assembly is positioned in the cylindrical section. A pair of oppositing jaws is pivotally secured between a center wall and a pair of side wall, respectively, of the trident section. The piston rod moves a cam assembly on the center wall. The cam assembly passes through a body having a trident section and cylindrical section. The trident section comprises a trident structure that includes, at one end, a pair of side walls along with a center wall. The cylindrical section includes a fluid driven powering assembly. A pair of opposing jaw member are pivotally secured to the trident portion about separate pivot pins. A cam assembly is operatively connected to a piston rod of the fluid driven powering assembly. The cam assembly extends laterally outward with respect to a cylinder bore axis to receive a cam bush that engages with a through slot on each of the pair of opposing jaw members. The jaws rotate with respect to one another in response to fluid power in the cylindrical section. A pair of side plate members, each slide plate member has an elongated blind slot that receives an end of the cam assembly, the ends travel in the blind slot. Cam slots in the pair of opposing jaws, via a cam bushing.
