  • Patent number: 10350750
    Abstract: An industrial robot may include multiple motors structured to rotate multiple arm units; multiple motor drivers to drive multiple motors; a power source to supply power to the multiple motor drivers; a charge-discharge unit connected to the multiple motor drivers; a control execution unit to control the multiple motor drivers; an elevation motor to elevate the arm, an elevation motor driver to drive the elevation motor; a first brake to stop the elevation motor; and a second brake to stop the elevation motor. When the industrial robot makes an emergency stop, the supplied power is turned off and control execution unit stops the multiple motors while controlling the multiple motor drivers by using the power supplied from the charge-discharge unit. The control execution unit controls at the time of said emergency stop, operates the first brake and then operates the second brake to stop the elevation motor.

  • Patent number: 9399285
    Abstract: An industrial robot that can control the abrasion and damage of a bearing unit, and also control the deformation of an arm, even in the case of transferring a high-temperature transfer object in a vacuum. The industrial robot includes a bearing unit for supporting an arm at a joint section as a connection section between the arm and the main body. At the joint section, the arm has a first protrusion section protruding toward the main body, and meanwhile the main body has a first housing section in which a first hollow section for housing the first protrusion section is formed. The first protrusion section and the first housing section are formed of a material having higher thermal conductivity than the bearing unit has, and a semisolid thermally-conductive substance, having higher thermal conductivity than the bearing unit has, is placed in the first hollow section.
