When the detection cylinder 602 drives the detection base 610 to move towards the jig 110, that is, the detection column 612 moves towards the bearing groove 111, when the detection cylinder 602 moves the detection base 610 to a preset distance, the detection column 612 and the workpiece in the bearing groove 111 contact each other, because the detection column 612 is in sliding fit in the detection hole 611, when the detection column 612 abuts against the workpiece, the workpiece is not crushed, but is blocked by the workpiece to slide in the detection hole 611, and meanwhile, the limit rod 614 in the limit groove 613 moves in the limit groove 613 and moves to the probe position of the photoelectric switch 615, so that the photoelectric switch 615 is triggered; if the workpiece is not successfully placed in the bearing groove 111 on the jig 110, when the detection cylinder 602 moves the detection base 610 downward to a preset distance, the detection column 612 cannot be blocked under the action of top touch of the labor price because the workpiece is not successfully placed on the jig 110, so that the detection column 612 cannot slide along the detection hole 611, that is, the probe of the photoelectric switch 615 cannot be triggered by the limiting rod 614.

Since the jig 110 is provided with corresponding workpieces exclusively at the positions of the shell feeding device 200, the core feeding device 300, and the carbon film body feeding device 400, the heights of the workpieces in the bearing grooves 111 at the three stations are different and are sequentially higher, and at this time, the distance that the detection cylinder 602 drives the detection base 610 to descend in the detection device 600 located at the downstream of the shell feeding device 200, the core feeding device 300, and the carbon film body feeding device 400 needs to be adjusted.

The embodiment of the invention provides a double-station automatic assembly device for a knob potentiometer, which comprises the following working procedures:

in the rotating process of the turntable 101, the jigs 110 positioned thereon are driven to sequentially flow through the shell feeding device 200, the detection device 600, the shaft core feeding device 300, the detection device 600, the carbon film body feeding device 400, the riveting and forming device 500 and the blanking device 700, and because the jigs 110 are provided with a plurality of jigs at equal intervals, continuous assembling and processing can be realized.

The process of sequentially passing a jig 110 through the above-described apparatus will now be briefly described: when the jig 110 is conveyed to the casing feeding device 200, the feeding vibration plate conveys the casing into the casing slot hole 211 on the casing carrying platform 210, the first mechanical hand 220 picks the casing and then places the casing into the bearing groove 111 of the jig 110, in the process of picking by the first mechanical hand 220, the material taking rod 235 made of magnetic material is adopted to adsorb the casing so as to suck the casing on the casing carrying platform 210, when the casing is arranged on the jig 110, the material taking rod 235 moves upwards along the sliding hole 234 under the action of the pulling cylinder 236, at the moment, the material taking block 233 separates the casing adsorbed on the material taking end 231 of the material taking rod 235, and the casing is arranged on the jig 110.

The jig 110 loaded with the housing is driven by the turntable 101 to move to the detecting device 600 located at the downstream of the housing feeding device 200, and at this time, the detecting device is used to detect whether the housing is successfully installed on the jig 110, specifically, after the detecting cylinder 602 drives the detecting base 610 to descend to a predetermined distance, whether the detecting column 612 is contacted by the housing installed on the jig 110, if the housing is loaded, the detecting column 612 slides along the detecting hole 611 under the blocking of the housing, so that the limiting rod 614 moves along the limiting groove 613 to the other end of the limiting groove 613, so as to trigger the probe of the photoelectric switch 615, and output a detecting signal, which indicates that the housing is successfully installed on the jig 110; if the housing is not successfully installed, the detection column 612 is not pushed and the photoelectric switch 615 does not output a signal.

When the jig 110 is driven by the turntable 101 to rotate to the relative position of the core loading device 300, the core vibrating plate 340 and the conveying device convey the core to the core placing position 311 of the core carrying table 310, at this time, if the assembly requirement requires to coat the core with the lubricating oil, the core is clamped on the core carrying table 310 under the action of the second manipulator 320 and then loaded on the oil coating column 365 of the oil coating mechanism 360, the rotating assembly drives the oil coating column 365 to rotate on the oil coating base, so that the oil coating assembly 370 uniformly coats the lubricating oil on the circumferential surface of the core, and then the lubricating oil is loaded on the jig 110 on which the core coated with the lubricating oil is loaded and is mutually overlapped with the shell on the jig 110.

Correspondingly, the turntable 101 drives the jig 110 to the detecting device 600 located at the downstream of the shaft core feeding device 300 for detecting whether the shaft core is successfully loaded on the jig 110, and the detecting method is the same as above, which is not repeated herein.

The jig 110 is moved to a position corresponding to the carbon film body feeding device 400 under the rotation of the turntable 101, and the carbon film body is loaded onto the jig 110 at the position, so that the carbon film body, the housing and the shaft core are stacked and assembled into the potentiometer shown in fig. 1, wherein the carbon film body passes through the bending mechanism 470 and the shaping mechanism 440 in the process of being conveyed to the carbon film body placing position 411 by the conveying channel 412, and is used for bending the pins of the carbon film body, so that the assembled potentiometer can be mounted on different electrical appliances, of course, the pins of the carbon film body can be not bent according to production requirements, and at this time, the bending mechanism 470 and the shaping mechanism 440 are in a device state; when bending and shaping are needed, the pressing cylinder 4711 moves the pressing plate 4712 towards the conveying channel 412 to press the pins onto the side wall 413 of the conveying channel 412, and at the moment, the bending rod 2722 is driven by the bending cylinder 4724 to extend out of the bending hole 4721 and bend the pins which correspond to the bending hole 4721 and are pressed by the pressing plate 4712 upwards; after bending, the carbon film body moves to the shaping mechanism 440 located at the downstream of the bending mechanism 470, and at this time, the shaping rod 443 is driven by the shaping cylinder 444 to move towards the stopper 441 and press the pins onto the baffle 442, so that the pins are pressed and shaped to be in a vertical state; at this time, the third robot 420 loads the carbon film body, which has been bent and shaped, onto the jig 110.

Similarly, the turntable 101 moves the jig 110 to the detecting device 600 located at the downstream of the carbon film body loading device 400, so as to detect whether the jig 110 is successfully loaded with the carbon film body, and the detection is performed as described above.

When the jig 110 moves to the riveting and pressing device 500, the jig is used for pressing the assembled three workpieces to be fixedly assembled, specifically, the pins on the housing are bent inwards, that is, the pins are bent towards the top surface of the carbon film body installed in the housing, so that the carbon film body is clamped on the top surface of the carbon film body, and the three workpieces can be stably assembled.

When the jig 110 moves to the discharging device 700, the discharging manipulator 701 of the discharging mechanism picks up the assembled potentiometer on the jig 110 and transfers the potentiometer onto the discharging plate 702, so that the potentiometer is collected by the feeding of the discharging plate 702.
