An industrial robot continuously and automatically executes a teaching step of learning a hand position that is the position of a hand when mounting a transported object to be placed in a predetermined position on a placing section, and a calibration step of correcting the hand position learned in the teaching step. In the calibration step, the hand is moved to the hand position identified in the teaching step, and a transported object for teaching placed in the predetermined position is mounted and taken out onto the hand. Thereafter, the hand is moved again to the hand position identified in the teaching step and the transported object for teaching is placed on the placing section. Afterward, the position of the transported object for teaching is detected by second sensors attached to the hand and the hand position is corrected based on the detection result by the second sensors.

Industrial robot and teaching method for industrial robot

A first sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a left-right direction. A second sensor is disposed in such a way that optical axes of a light emitting element and a light receiving element thereof are parallel to a front-rear direction. When a position of a wafer to be loaded on a loading portion is taught, a position of the loading portion or a teaching jig to be loaded on the loading portion in the front-rear direction is detected by the first sensor by moving a hand in the front-rear direction by a moving mechanism, and a position of the loading portion or the teaching jig in the left-right direction is detected by the second sensor by moving the hand in the left-right direction by the moving mechanism.

Industrial robot

A window regulator includes a guide rail, a carrier plate, and a raising/lowering means to raise/lower the carrier plate along the guide rail. The carrier plate includes a front surface sliding member configured to slide on a front surface of a flange portion of the guide rail and a back surface sliding member configured to slide on a back surface of the flange portion. The back surface sliding member includes a contact portion coming into contact with the back surface and a base portion that presses the contact portion against the back surface by a restoring force of elastic deformation. The contact portion extends toward the back surface and is elastically deformed and bent on the end side to allow the flange portion to enter from a lateral side in an extending direction thereof when assembling the carrier plate to the guide rail.

Window regulator

A window regulator includes a guide rail provided along an ascending/descending direction of a window of a vehicle, a carrier plate that slides on the guide rail and moves together with the window, cables that pulls the carrier plate, a drum that is rotationally driven by a motor, and a housing that includes a drum housing accommodating the drum and a motor housing fixed to the drum housing and accommodating a portion of the motor. The drum housing includes a fitting portion including a fitting hole to insert a lower end of the guide rail and a fastening hole used to fasten the motor housing. The fastening hole of the drum housing is provided at a position overlapping the guide rail in a longitudinal direction of the vehicle.

A window regulator includes a metal guide rail provided along an ascending/descending direction of a window of a vehicle, a carrier plate that slides on the guide rail and moves together with the window, a drum rotationally driven by a motor, a cable that is routed between the drum and the carrier plate via a direction changing member provided at an upper end of the guide rail and pulls the carrier plate, and a cable support that supports the cable between the drum and the direction changing member. The cable support includes a resin slide member allowing the cable to slide thereon and an attached-member receiving portion to which the slide member is attached. The attached-member receiving portion is integrated with the guide rail.
