The elastic body 2 is fixed to one end portion of the elastic support 1 with an adhesive, an adhesive, caulking, screwing, or the like. Preferably, the one end portion separated from the end portion of the elastic support by a dimensional distance of 1/2 to 4 times the thickness of the elastic body (preferably about 1 to 10 mm) is preferable. When the parts chucked on the working table are transported and arranged by being fixed at such a distance, the end of the elastic support member comes into contact with the working table, and the elastic support member 1 (without contact with the elastic member). Elastic support by smooth sliding of one end of the end (R chamfering to make the end tip easy to slip, processing bent into an R shape, attaching Teflon (R), fluorine coating, etc.) When the distance between the body and the elastic support body increases, the distance L between the elastic body and the elastic body increases, and the component is released from biting into the elastic body 2 and placed in a fall state.
[0007]
The other end of the elastic support 1 to which the elastic body 2 is fixed is fixed to the block of the transport support 4 by a fixing jig 6 so that the plurality of elastic bodies are arranged at a size position sandwiching the components. The In other words, the distance L between the elastic bodies / elastic bodies sandwiching the parts is determined by the block size of the transport support. The fixed elastic support is preferably in a state where it is opened by 10 to 45 degrees from the vertical direction. The elastic support may be bent into a dogleg shape, and the fixing position of the transport support is processed into a taper shape. May be. It is also possible to add an adjusting jig 7 for adjusting the position of the elastic body by fine adjustment of the fixed elastic support. A sensor 3 (optical type, magnetic type, microswitch type, contact type, etc.) for confirming that the elastic support / elastic body has chucked the part may be added. (Parts are sandwiched between elastic bodies and elastic bodies, and the elastic support moves when the parts are spread out to operate the sensor. For this purpose, the elastic support with the sensor attached is another elastic support. It is preferable that the elastic force is weaker than that and it is easy to move.)
[0008]
Such a component conveying device is fixed to the main body device by the mounting body 5. In order to reduce damage at the time of contact with a component, a shock absorber (a spring device, an air device, a magnetic device, or the like for canceling the weight of the component conveying device) may be applied to the mounting body 5.
[0009]
Parts transported by the parts transporter are not limited to round, oval, polygonal, etc. shapes, but are not limited to ceramic, metal, plastic, wood, glass, semiconductor, etc. materials It does not limit the dimensions, thickness, etc., but does not limit whether or not other parts are mounted.
[0010]
The parts transport device moves so that the gap with the mountain of the parts narrows and comes into contact, the parts enter between the elastic bodies and the elastic bodies / elastic support bodies open, and the corners around the parts move. The elastic body bites into the elastic body a little, and the elasticity of the elastic body / elastic support body catches and moves only the uppermost part, moves down to the working base, and the end of the elastic support body contacts the working base. The elastic support moves so that it slides, the elastic body / elastic support opens, the parts are released from biting into the elastic body, and the conveyed parts are dropped to a predetermined position. The Such a component conveying apparatus can convey components only by using an elastic force, so that a complicated opening / closing drive mechanism is unnecessary, soft touch is not required, and an opening / closing driving program is not required and the cost is low.
