Abstract: A workpiece conveyance pallet which can reduce the manufacturing cost and improve the reliability. The workpiece conveyance pallet includes a rest surface on which a workpiece is mounted, and a clamping mechanism which clamps the workpiece, the clamping mechanism including an openable and closable, first claw and second claw, a biasing section which biases the first claw and the second claw in the closing direction, and a movement restriction section which detachably engages with the first claw and the second claw when the first claw and the second claw are opened.

Abstract: A temporary placement device comprises a carrying member having a carrying surface on which a workpiece is placed and a drive device driving the carrying member. The carrying member is formed to be deformable. The drive device includes a connecting member connected to a center part of the carrying member and moving in an up-down direction. The drive device moves the connecting member between a top end position where the carrying surface of the carrying member becomes flat and a bottom end position where the carrying surface becomes recessed downward.

Abstract: A workpiece convey system comprising two conveyor devices which alternately convey workpieces from a source area to a destination area, wherein each of the two conveyor devices is provided with a workpiece holding part which can hold a workpiece, and a movement mechanism which moves the workpiece holding part back and forth between the source area and the destination area, the two conveyor devices being arranged so as to match the positions where their respective workpiece holding parts are stopped within the source area.

Abstract: A chuck device capable of efficiently changing a welding tip and nozzle. The chuck device includes a rotatable chuck base, an engagement part fixed to the chuck base so as to rotate integrally with the chuck base and can engage an engagement surface of the welding tip, the engagement part allowing the welding tip to rotate with the chuck base when the chuck base is rotated while engaged with the engagement surface, and a plurality of fingers provided to the chuck base to be openable and closable and can hold the welding tip and the nozzle, the plurality of fingers being capable of moving in directions approaching and separating from the engagement part.

Abstract: A workpiece clamping device able to clamp a first workpiece and a second workpiece placed on the first workpiece. The workpiece clamping device includes a receiving base on which the first workpiece is to be placed, a first clamping mechanism for clamping the first workpiece, and a second clamping mechanism for clamping a second workpiece placed on the first workpiece. The first clamping mechanism has a first clamp section and a second clamp section, which are provided on the receiving base so as to open and close. The second clamping mechanism has a third clamp section and a fourth clamp section, which are provided on the receiving base so as to open and close, to retain the second workpiece at a predetermined position with respect to the first workpiece.

Abstract: A robot system comprises a first robot which supports a suspending jig for suspending a workpiece, a second robot which supports a hand, and a control device which performs cooperative control for causing the first robot and the second robot to operate cooperatively. The hand grasps the workpiece at a portion which is lower than a mating portion of the workpiece. In the robot system, the control device performs cooperative control so that the workpiece is conveyed while a condition in which the hand grasps the article is maintained.
