[0041] This embodiment also provides a synthesis method of an EPS worm O-ring automatic synthesis device, comprising the following steps: Step 1: According to actual needs, select the required specifications of O-rings, and then select different product programs. Two sets of O-ring vibration plates, direct vibration guides, O-ring interfaces and push plates are selected to work one by one.
[0042] In this embodiment, taking the D621111 model O-ring as an example, the external PLC starts the first O-ring vibration disk and the first straight vibration guide rail corresponding to the first O-ring vibration disk, so that the O-ring enters the first straight vibration guide rail from the discharge port, and enters the first O-ring interface and slides into the first pushing plate through the vibration of the first straight vibration guide rail.

[0043] Step 2, the magnetic induction switch of the first cylinder is energized, and after receiving the signal, the PLC instructs the seventh cylinder to push the O-ring picking / feeding device to move in the positive direction of the X-axis. When it moves to the waiting position of the O-ring feeding device (i.e., the position of the U-shaped profiling groove of the first push plate), the magnetic induction switch at the positive end of the X-axis on the seventh cylinder is energized, so that the chuck is in a clamping state, and drives the O-ring clamping claw to retract inward, and the third cylinder extends toward the negative direction of the Z-axis until the magnetic induction switch at the negative end of the Z-axis on the third cylinder receives a signal; because there is a circle of magnets on the piston ring in the cylinder, the magnetic induction switch is installed on the cylinder, and it will light up when it senses the magnetic field, and it is in the energized state at this time; The PLC instructs the seventh L-shaped plate to move in the negative direction of the Z axis, the O-ring clamping claw is inserted into the O-ring, reaches the upper surface of the fixed block and is in full contact, the chuck is opened, and the O-ring clamping claw opens to support the O-ring; the magnetic induction switch on the chuck pneumatic cylinder is energized, the third cylinder retracts in the positive direction of the Z axis, and the seventh L-shaped plate moves in the positive direction of the Z axis. After it is in place, the positive magnetic induction switch of the Z axis on the third cylinder receives a signal, and the seventh cylinder pushes the O-ring picking / feeding device body to move in the negative direction of the X axis until it moves to the original position, that is, directly above the O-ring rod. After reaching the position, the negative magnetic induction switch of the X axis on the seventh cylinder is energized, the third cylinder extends in the negative direction of the Z axis, the seventh L-shaped plate moves in the negative direction of the Z axis, and the O-ring clamping claw is connected to the O-ring rod until the negative magnetic induction switch of the Z axis on the third cylinder receives a signal. The four cylinders retract, driving the sixth plate and the eighth base plate to move in the negative direction of the Z axis. Since the clamp passes through the mounting hole on the eighth plate and opens to be completely flush with the inner diameter of the mounting hole, when the eighth base plate moves in the negative direction of the Z axis, the bottom plane around the mounting hole pushes the O-ring on the clamp to the O-ring rod; until the magnetic induction switch at the negative end of the Z axis of the fourth cylinder is energized, the fourth cylinder extends, driving the sixth plate and the eighth base plate to move in the positive direction of the Z axis; until the magnetic induction switch at the positive end of the Z axis of the fourth cylinder is energized, the chuck retracts, the O-ring clamp closes, the third cylinder retracts, and the seventh L-shaped plate moves in the positive direction of the Z axis to the initial position, that is, directly above the O-ring rod, until the magnetic induction switch at the positive end of the Z axis on the third cylinder receives a signal.
[0044] Step 3, the robot grabs the worm and places it on the worm composite pre-swing tooling, the fifth cylinder extends out, driving the tenth vertical plate to move in the negative direction of the Y axis as a whole, until the O-ring sleeve rod is directly below the worm, the magnetic induction switch at the negative end of the Y axis of the fifth cylinder is energized, the sixth cylinder retracts, the twelfth base plate and the sleeve rod mechanism installed thereon move in the positive direction of the Z axis as a whole, until the sleeve rod touches the circular bottom of the worm; at this time, the sleeve rod no longer moves due to the hard limit at the bottom of the worm, the twelfth base plate, the eleventh flat plate and the ring sleeve continue to compress the spring and move in the positive direction of the Z axis, and the upper surface of the sleeve ring pushes the O-ring from the sleeve rod to the annular groove of the worm; after the O-ring enters the groove, the cylinder 6, the magnetic induction switch at the positive end of the Z axis is energized, the sixth cylinder extends, the twelfth base plate and the sleeve rod mechanism installed thereon move downward as a whole to the initial position, that is, the twelfth base plate is completely in contact with the upper supporting surface of the thirteenth L-shaped plate, the magnetic induction switch at the negative end of the Z axis of the sixth cylinder is energized, the fifth cylinder retracts, driving the tenth vertical plate to move backward as a whole to the initial position, the magnetic induction switch at the positive end of the Y axis of the fifth cylinder is energized, the robot grabs the worm of the synthesized O-ring to the next workstation, and returns to the initial position to grab the next worm to be synthesized O-ring and place it on the worm synthesis pre-swing tooling, and continues to carry out the next synthesis cycle of the worm and O-ring.
