Abstract
The invention a rivet placement detection device. A pressing plate can slide longitudinally and is positioned on a fixed support, and a driving device drives the pressing plate to move. Detection ejector pins can slide longitudinally for distance setting, and are positioned on the pressing plate. An elastic piece and the detection ejector pins are connected with each other, and the detection ejector pins maintain a movement tendency to be located at the lowermost position in a movement direction. The lower end of each detection ejector pin can be inserted into a carrier exactly under the pressing plate, and abuts against an upper end face of a rivet in the carrier. A plurality of first sensing devices can respectively sense the height position of the upper end face of the corresponding detection ejector pin, and transmit the height information to a controller. A second sensing device can sense the height position of an upper side surface of the carrier exactly under the pressing plate, and transmits the height information to the controller. The controller controls the driving device to act, and controls a result output device to output detection results. The device can sufficiently detect various misplacement and missing placement circumstances, is high in precision and efficiency of detection, avoids manual detection, saves manpower cost, and reduces the reject ratio of spot welding.

Embodiment
Embodiment: a kind of rivet is filled out and put pick-up unit, comprise fixed support 1, first, two induction installations 2, 3, pressing plate 4, drive unit 5, detect thimble 6, elastic component 7, result output unit and controller, described pressing plate 4 can longitudinal sliding motion be positioned on fixed support 1, drive unit 5 drives pressing plate 4 to move, detecting the longitudinal setpoint distance that can slide of thimble 6 is positioned on pressing plate 4, elastic component 7 is connected with detection thimble 6 and keeps detecting the movement tendency that thimble 6 has the lowest positions being in its direction of motion all the time, detection thimble 6 lower end can insert in the carrier immediately below the pressing plate 4 and rivet upper surface be tight against in carrier respectively, some first induction installations 2 can sense each height and position detecting thimble 6 upper surface respectively and be messaging in controller, second induction installation 3 can sense the height and position of the carrier uper side surface immediately below pressing plate 4 and be messaging in controller, controller accessory drive 5 action and result output unit output detections result, during work, the carrier that product and the rivet treating spot welding is housed just is placed in immediately below pressing plate 4, second induction installation 3 senses the height position information of carrier uper side surface and delivers a letter to controller, if detect that carrier uper side surface position height is higher than setting height, represent that rivet that in carrier, thickness is large mistake is filled out and be placed on the little rivet location in the thick end, detect defective, if detect that carrier uper side surface position is not highly higher than setting height, then indicate without this kind of unfavorable condition, controller controls pressing plate 4 and moves downward, detection thimble 6 on pressing plate 4 to extend in carrier and is tight against each rivet upper surface, now each detection thimble 6 upper surface height and position responded to by some first induction installations 2, if any one detects thimble 6 upper end level lower than setting height, then represent that rivet little for misplaced for rivet large for thickness one-tenth thickness misses or leaks by mistake by this position and put rivet, after detection terminates, controller controls result output unit output detections information, this structure of the detecting device is simple, easy to operate, detection speed is fast, and testing result is accurately detailed.
