Attaching device
Provided is an attaching device that can convey a component, such as a nut, to a portion to be welded without using an air cylinder. The present invention provides an attaching device ( 100 ) that attaches a nut ( 240 ) to a bracket ( 230 ). The attaching device ( 100 ) has a component feeding part ( 10 ) that stores the nut therein, a welding part ( 40 ) that welds the nut to the bracket by using electrodes ( 41, 42 ), a conveying part ( 20 ) that conveys the nut stored in the component feeding part to a position where the nut is to be attached to the bracket, and a feeding head ( 30 ) that temporarily positioned between the electrodes ( 41, 42 ) and that places the nut conveyed from the conveying part on the lower electrode of the pair of electrodes.
1. An attaching device for attaching a nut to a counterpart component,
comprising:
a storage part storing a plurality of the nuts;
a welding part welding the nut to the counterpart component by a pair of electrodes;
a conveying part having a flexible long member for conveying the nut stored in the storage part singly to the welding part; and
a placement part provided at an outlet of the long member on a side of the welding part, and temporarily getting close between the pair of electrodes of the welding part to place the nut
wherein the placement part has a moving part,
the moving part together with the outlet is capable of moving to and away from the pair of electrodes in a direction crossing a direction in which the pair of electrodes is aligned,
the moving part together with the outlet being configured to get close between the pair of electrodes of the welding part until the nut is sent out from a delivery portion provided at the storage part, and
with the moving part being configured such that when the moving part is close between the pair of electrodes, the nut sent out from the delivery portion is placed on a lower electrode of the pair of electrodes after passing through the placement part singly from the conveying part.
2. The attaching device according to claim 1 ,
wherein the long member extends in a direction intersecting a direction in which the pair of electrodes is aligned,
the moving part is connected to the outlet, and
the placement part has a direction changing part which is connected to the moving part and directs a traveling direction of the nut coming out of the outlet of the long member to the lower electrode.
3. The attaching device according to claim 1 , wherein the counterpart component is attached to a sub-frame of a suspension.
