At this time, the electric screwdriver 524 The output end contacts the screw; the vacuum generator picks up the screw on the screw feeder 7 through the screw suction head 525 and the suction hole 526, and the Z-axis linear module 223 drives the mounting frame 224 to reset, and then drives the screw to move with the cooperation of the X-axis linear module 221, the Y-axis linear module 222 and the Z-axis linear module 223, and takes a picture of and locates the screw through the lower camera module 102; under the positioning and guidance of the upper camera module 101 and the lower camera module 102, the X-axis linear module 221, the Y-axis linear module 222 and the Z-axis linear module 223 drive the mounting frame 224 to move, thereby driving the locking cylinder 521, the slide rail 522, the moving plate 523, the electric screwdriver 524, the screw suction head 525 and the screw on the mounting frame 224 to move, straight Until the screw is aligned with the screw holes on the casing 8 and the headphone jack 9; the Z-axis linear module 223 drives the mounting bracket 224 to move, so that the screw at the end of the screw suction head 525 moves to the upper side of the screw hole, and then the locking cylinder 521 drives the moving plate 523 to move, and the moving plate 523 moves vertically under the limiting action of the slide rail 522, and the electric screwdriver 524 is started at the same time, and the screw is locked through the cooperation of the electric screwdriver 524 and the locking cylinder 521; after locking one screw, the locking cylinder 521 drives the moving plate 523 to reset, thereby driving the electric screwdriver 524 and the screw suction head 525 to reset, and the X-axis linear module 221, the Y-axis linear module 222 and the Z-axis linear module 223 drive the mounting bracket 224 to reset; then repeat the above actions to perform the second screw hole. The screws are locked; after the two screws are completely locked, the motor linear slide drives the laser head to move, and the laser head extends out to align with the connecting hole 81, and the relative positions of the connecting hole 81 and the jack protrusion 91 at the lower edge and both side edges of the connecting hole 81 are detected by the laser head to determine whether the assembly meets the requirements; after the detection, the motor linear slide drives the laser head to reset; the turntable module 21 drives the assembled housing 8 and the headphone jack 9 to rotate to the loading and unloading station. During this process, the clamping block 429, the positioning rod 412, and the floating push block 324 are reset synchronously, and the locking of the housing 8 and the headphone jack 9 is canceled, so that when the housing 8 and the headphone jack 9 rotate to the loading and unloading station, the operator can directly take out the assembled housing 8 and the headphone jack 9.
