The specific assembling process of the valve spring 101 is as follows: the spring carrier 310 receives the valve spring 101 at the spring receiving mechanism 410, adjusts the orientation of the valve spring 101 as it is transported past the spring adjustment mechanism 420, so that the valve springs 101 are uniformly oriented, and then the spring carrier 310 is transported to the terminal receiving mechanism 430, receives the valve terminals 102, the valve terminal 102 is pressed and fixed on the valve spring 101 at the spring pressing mechanism 440, the spring carrier 310 operates step by step, the flatness of the valve terminal 102 mounted to the valve spring 101 is detected at the spring detecting mechanism 450, thereby judging the assembling effect of the valve spring 101 and the valve terminal 102, and after the detection of the valve spring 101 is completed, the valve spring 101 and the valve terminal 102 are grabbed and transferred at the spring gripper mechanism 460 into the respective magazine, finally, the spring carrier 310 is detected in the empty position detecting mechanism 470, so as to determine whether the empty position detecting mechanism 470 is operating normally.
In the above assembling process, after the valve spring 101 is transported to the spring adjusting mechanism 420 under the carrying of the spring carrier 310, the pushing cylinder 425 on the long wall of the adjusting base 421 pushes the adjusting frame 422 downward, the adjusting frame 422 continuously moves downward along the adjusting rail 423, and finally the adjusting frame 422 is attached to the limiting strip 424, at this time, the adjusting frame 422 is covered above the bearing column 312 in the spring carrier 310, the sensing cylinder 481 is started, the touch sensor 426 descends, the touch sensor 426 in the adjusting frame 422 contacts with the end surface of the valve spring 101 on the bearing column 312, the touch sensor 426 determines the orientation of the valve spring 101 according to the contact area with the valve spring 101, when the touch sensor 426 contacts with a smaller end surface, the clamping cylinder 427 is started, the adjusting clamping jaw 483 on the piston end of the clamping cylinder 427 is tightened, the valve spring 101 on the bearing column 312 is clamped, and then the pushing cylinder 425 is retracted, the valve spring 101 disengages the load post 312. When the touch sensor 426 contacts the larger end face, the adjustable jaws 483 on the piston end of the clamp cylinder 427 open.
Under the driving of the pushing cylinder 425, the valve spring 101 is separated from the bearing column 312 and ascends to the initial position, the piston column of the sensing cylinder 481 is retracted, then the state of the adjusting clamping jaw 483 is judged, if the adjusting clamping jaw 483 is in a tightening state, the adjusting cylinder 428 operates, the overturning plate 486 is driven by the adjusting cylinder 428 to rotate for 180 degrees in the adjusting frame 422, the valve spring 101 is changed from a small end to an big end to the big end, then the pushing cylinder 425 is started for two times, the adjusting frame 422 is driven to the upper part of the spring carrier 310, the sensing cylinder 481 is started again, and the adjusting effect of the valve spring 101 is detected.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
