A multi-axis robot includes: a robot main body including a head and a movement mechanism that three-dimensionally moves the head; and a work tool attached to the head. The work tool includes: a first link pivotally supported on the head; a second link pivotally supported on a distal end of the first link; a first change mechanism that changes an angle of the first link to a central axis of the head; and a second change mechanism that changes an angle of the second link to the first link.

Multi-axis robot and control method therefor, and work tool

A robot system includes a robot that self-travels along a traveling shaft and is provided with a position detection sensor at a distal end, a support member that has a plurality of reference positions juxtaposed and supports a workpiece, a plurality of calibration members that are juxtaposed along the traveling shaft, and a control device, in which the calibration members each have a calibration position, and the control device is configured to cause the robot to move by a predetermined first distance along the traveling shaft, calibrate position coordinates of the robot based on position coordinates of the calibration positions detected by the position detection sensor, and subsequently calibrate position coordinates of the workpiece based on position coordinates of the reference positions detected by the position detection sensor.

Robot system and operating method thereof

An end mill includes: a columnar tool body that rotates about a center axis; and outer peripheral cutting edges on an outer peripheral surface of the tool body, the outer peripheral cutting edges including a first outer peripheral cutting edge and a second outer peripheral cutting edge. A relief angle &#x3b8; of the first outer peripheral cutting edge changes to increase in an axial direction of the tool body from a bottom face that is one end of the tool body. A relief angle &#x3b8; of the second outer peripheral cutting edge changes to decrease in the axial direction from the bottom face.

End mill

An object is to suppress a variation in amount of a sealant that is applied on an object to be sealed. There is provided a sealant discharge nozzle configured such that a sealant from a cartridge is discharged from a discharge hole of the sealant discharge nozzle. The sealant discharge nozzle has a leading end portion comprising a pair of side wall portions; and a connecting wall portion configured to connect the pair of side wall portions with each other and provided in cooperation with the pair of side wall portions to form a first recess that is open on one side in a first direction perpendicular to an axial direction of the sealant discharge nozzle, and on a leading end side. The discharge hole has an opening formed on a first recess side of the connecting wall portion.

Sealant discharge nozzle and sealant discharge apparatus

A controller controls a plunger to operate at a measurement speed and discharge the viscous material from the nozzle before applying the viscous material to the workpiece. The controller measures a period of time, from when the plunger starts operating at the measurement speed until a discharge amount of the viscous material reaches a predetermined value, as a time delay amount. The controller further determines an operation speed of the plunger and/or a moving speed of the nozzle during application of the viscous material to the workpiece according to the measured time delay amount.

Viscous material discharge device

A viscous material wiping device wipes the viscous material attached to the tip of a spatula with a sheet. A sheet support jig has a groove recessed in the sheet facing surface, the groove includes a receiving portion and a wiping portion that are continuous in the groove extending direction, and the wiping portion has a groove width smaller than that of the receiving portion and substantially equal to the outer dimension of the tip of the spatula. A controller drives the moving mechanism to position the spatula on the opposite side of the sheet supporting jig with respect to the sheet in a posture that the spatula extends parallel to the groove extending direction and overlaps the groove when viewed in a normal direction of the sheet facing surface, and move the spatula in the normal direction so that the tip of the spatula is received in the receiving portion by pressing the sheet against the groove with the spatula. The spatula is configured to move in the groove extending direction so that the tip of the spatula passes through the wiping portion.

Viscous material wiping device

A transfer apparatus includes first and second holding portions, a hand, a hand moving portion, and fluid pressure driving and control units. The control unit acquires an inter-holding portion distance between the first and second holding portions for holding a workpiece. The control unit makes the hand moving portion move the hand to a predetermined position such that the distance between the first and second holding portions becomes the inter-holding portion distance when the first holding portion moved by the fluid pressure driving unit is brought into contact with a contact portion provided at a work field, the predetermined position being located away from the contact portion. With the hand located at the predetermined position, the control unit makes the fluid pressure driving unit move the first holding portion to contact with the contact portion, and the control unit stops driving of the fluid pressure driving unit.
