An industrial robot includes a mounting mechanism on which multiple conveyance objects is mounted. The mounting mechanism includes multiple hands overlapped with each other at a predetermined pitch in an upper and lower direction. Each of the hands includes: a fixing part to which a fixed part of the mounting part is fixed, and a bolt for fixing the fixed part to the fixing part. When the mounting mechanism includes a hand having an upward bolt, all of the fixing parts and the fixed parts of the hands disposed on a lower side of the upward bolt are formed with through holes for engaging a tool with a head part of the upward bolt from a lower side of the hand disposed at the bottom. An inside diameter of the through hole is larger than an outside diameter of the head part.

A horizontal articulated robot may include a hand; an arm having at least two arm portions including a supporting-arm portion to which said hand is rotatably joined and a supported-arm portion to which the base end of said hand-side arm portion is rotatably joined; a main body portion; and a rotation mechanism structured to rotate said supported-arm portion. The rotation mechanism may include a motor which is arranged such that an axial direction of an output shaft of the motor coincides with a horizontal direction; a Harmonic Drive (registered trade mark) wave-motion gearing device structured to reduce the power of said motor; a first bevel gear coupled to said output shaft; and a second bevel gear coupled with a wave generator of said Harmonic Drive (registered trade mark) wave-motion gearing device and which meshes with said first bevel gear.

An industrial robot may include a robot main body; and an elevating mechanism to raise and lower the robot main body. The robot main body may include a hand, an arm to which the hand is joined, a main body portion to which the arm is joined, and an arm-elevating mechanism. The elevating mechanism may include a drive unit, guide rails, a guide block, and a joining member joining the robot main body and the guide block. The housing may include a flat cover between the guide block and the main body unit. Slit through-holes may be formed in the cover to enable the joining member to move in the up-down direction.

A horizontal articulated robot in which an arm moves in the horizontal direction for use with objects to be transferred may include a hand on which the objects are to be mounted. The arm may have at least two arm portions including a hand-side arm portion to which the hand is rotatably joined to the front end thereof; and a second hand-side arm portion to which the base end of the hand-side arm portion is rotatably joined to the front end thereof; and a main body portion to which the base end of the arm is rotatably joined. A level which may be attached to the hand, the arm or the main body portion after an inclination of a center axis of rotation of the hand-side arm portion with respect to the second hand-side arm portion is adjusted relative to the vertical direction.

Horizontal articulated robot and method for manufacturing horizontal articulated robot

An industrial robot includes a robot main body and an elevating mechanism to raise and lower the robot main body. The robot main body may include a hand, an arm to which the hand is joined, a main body portion to which the arm is joined, and an arm-elevating mechanism. The center of rotation on the base end side of the arm may be located farther toward the third direction side than the center of the main body unit when viewed in the up-down direction. In the standby state, part of the arm may be positioned farther toward the fourth direction side than the main body unit. The main body unit may be secured to the elevating mechanism. The elevating mechanism may be arranged on one or both sides of the main body unit in the first direction and/or on the fourth direction side.
