In this embodiment, the X-axis represents the length direction of the equipment tabletop (which is also the left-right direction of the device movement), the Y-axis represents the width direction of the equipment tabletop (which is also the front-back direction of the device movement), and the Z-axis represents the height direction (which is also the up-down direction of the device movement).
[0036] The robot is placed on the left side along the Y-axis direction of the equipment tabletop. The O-ring feeding device, the O-ring picking / sending device, and the O-ring receiving / synthesizing device are all installed on the right side of the robot. Among them, the O-ring feeding device is arranged along the X-axis direction, and the O-ring receiving / synthesizing device is arranged along the Y-axis direction.

The end of the linear vibrating guide is provided with a feeding port for placing the O-ring, and it realizes cooperative feeding with the O-ring vibrating disk.
[0038] The worm synthesis pre-swing tooling is arranged behind the O-ring picking / sending device and is arranged along the X-axis direction of the equipment tabletop, and is used to place the worm and wait for the synthesis of the O-ring.
[0039] The O-ring feeding device is composed of a first support mechanism and a feeding mechanism installed above it. Among them, the first support mechanism is composed of a first bottom plate 4 and a second bottom plate 6 arranged in parallel and four first columns 5 vertically fixed between the two, and the feeding mechanism is installed above the second bottom plate.
[0040] The feeding mechanism includes a fixed block 13 for receiving O-rings transferred by the vibrating bowl.

And on the upper surfaces of the first pushing plate and the second pushing plate, there are U-shaped O-ring profiling grooves. When the O-ring at the back vibrates, it pushes the previous O-ring into the profiling groove.
[0041] The O-ring picking / sending device includes a second support mechanism and the O-ring picking / sending device body. The O-ring picking / sending device body is connected to the second support mechanism through the third slider guide rail 31.
[0042] The second support mechanism is composed of a third bottom plate 16 and a fourth vertical plate 17 distributed perpendicular to each other. The third bottom plate is horizontally placed on the support, and the fourth bottom plate is fixed above the third bottom plate and is horizontally distributed with the O-ring feeding device. The third slider guide rail is installed along the horizontal direction of the fourth bottom plate.

[0043] The O-ring picking / sending device body includes a fifth vertical plate 20, which is installed on the third slider guide rail and is driven to reciprocate through the third slider guide rail.
[0044] At the same time, the fifth vertical plate is connected with a seventh L-shaped plate 25 through the second slider guide rail 19. The vertical plate of the seventh L-shaped plate is connected to the piston rod of the third cylinder, and it is driven to move up and down by the third cylinder.

A fourth cylinder 24 is also installed on the horizontal plate of the seventh L-shaped plate, and the piston rod of the fourth cylinder is connected to the sixth flat plate, driving the sixth flat plate and the eighth bottom plate to move up and down;
[0045] A pneumatic chuck 26 is installed between the seventh L-shaped plate and the eighth bottom plate. The pneumatic chuck is tightly connected to the jaws 27 below the eighth bottom plate through bolts, and the jaws are driven to open and close by the pneumatic chuck.
[0046] The upper and lower ends of the column group are respectively fixedly connected to the sixth flat plate and the eighth bottom plate through bolts, and it includes two second columns 22 and two third columns 28. The second and third columns are respectively fixed to the upper and lower ends of the horizontal plate of the seventh L-shaped plate, and both are of hollow design. Connecting rods respectively penetrate through the interiors of the second column and the third column, and the second column and the third column are connected into one body through the connecting rods.
[0047] The O-ring feeding / synthesizing device is fixedly installed on the thirteenth L-shaped plate 42 and consists of a driving sliding mechanism and an O-ring sleeving rod 37. Among them, the driving sliding mechanism includes a ninth vertical plate 33 installed at the top of the thirteenth L-shaped plate. A fifth cylinder 32 is installed on the ninth vertical plate.

The tenth vertical plate is driven by the fifth cylinder to move horizontally on the fourth slider guide rail.
[0048] Meanwhile, a sixth cylinder 35 is also installed on the tenth vertical plate. The piston rod of the sixth cylinder is connected to a twelfth bottom plate 41. Two fourth columns 40 are symmetrically installed at both ends above the twelfth bottom plate and are fixedly connected to an eleventh flat plate 39 through the fourth columns. A ring sleeve 38 is installed on the eleventh flat plate. The O-ring sleeving rod is installed in the hollow part of the ring sleeve and is integrated with a connecting rod 44 through a coupling 46. A spring is sleeved on the connecting rod. In the original state, the spring supports the O-ring sleeving rod and the connecting rod on the twelfth bottom plate, and the upper end of the coupling is limited by the eleventh flat plate.
[0049] The working process of this embodiment is as follows:
[0050] Step 1, according to actual requirements, select the O-ring of the required specification, and thus select different product programs. Two groups of O-ring vibrating bowls, linear vibrators, O-ring interfaces and push plates work alternately.
[0051] In this embodiment, taking the O-ring of model D621111 as an example, the externally connected PLC starts the first O-ring vibrating bowl and the first linear vibrator corresponding to the first O-ring vibrating bowl to work, so that the O-ring enters the first linear vibrator from the discharge port and enters the first O-ring interface and slides into the first push plate through the vibration of the first linear vibrator. When the O-ring reaches the limit position of the first push plate, that is, the inner wall of the U-shaped profiling groove of the push plate, the infrared proximity sensor installed at the center of the arc surface of the U-shaped profiling groove of the push plate is powered on. After the PLC receives the signal, it commands the first cylinder to extend forward, driving the first push plate to the intermediate material-taking position of the fixed block.
[0052] Step 2: The magnetic induction switch of the first cylinder is powered on. After the PLC receives the signal, it instructs the seventh cylinder to push the O-ring picking / feeding device to move in the positive X-axis direction. When it moves to the position where the O-ring feeding device is to be picked up (i.e., the position where the U-shaped profiling groove of the first push plate is located), the positive X-axis magnetic induction switch on the seventh cylinder is powered on, causing the chuck to be in a clamped state and driving the O-ring jaws to contract inward. The third cylinder extends in the negative Z-axis direction until the negative Z-axis magnetic induction switch on the third cylinder receives a signal. Since there is a ring of magnets on the piston ring in the cylinder and the magnetic induction switch is installed on the cylinder, it will light up when it senses the magnetic field, and it is in the powered-on state at this time.
[0053] The PLC instructs the seventh L-shaped plate to move in the negative Z-axis direction. The O-ring jaws are inserted into the O-ring, reach the upper surface of the fixed block and come into full contact. The chuck opens, and the O-ring jaws open to hold the O-ring. The magnetic induction switch on the chuck pneumatic cylinder is powered on. The third cylinder retracts in the positive Z-axis direction, and the seventh L-shaped plate moves in the positive Z-axis direction. After reaching the position, the positive Z-axis magnetic induction switch on the third cylinder receives a signal. The seventh cylinder pushes the body of the O-ring picking / feeding device to move in the negative X-axis direction until it moves to the original position, that is, directly above the O-ring sleeve rod. After reaching the position, the negative X-axis magnetic induction switch on the seventh cylinder is powered on. The third cylinder extends in the negative Z-axis direction, and the seventh L-shaped plate moves in the negative Z-axis direction. The O-ring jaws are connected to the O-ring sleeve rod until the negative Z-axis magnetic induction switch on the third cylinder receives a signal. The fourth cylinder retracts, driving the sixth flat plate and the eighth bottom plate to move together in the negative Z-axis direction. Since the jaws pass through the mounting holes on the eighth flat plate and open to completely fit the inner diameter of the mounting holes, when the eighth bottom plate moves in the negative Z-axis direction, the bottom plane around the mounting holes pushes the O-ring on the jaws onto the O-ring sleeve rod. Until the negative Z-axis magnetic induction switch of the fourth cylinder is powered on, the fourth cylinder extends, driving the sixth flat plate and the eighth bottom plate to move together in the positive Z-axis direction. Until the positive Z-axis magnetic induction switch of the fourth cylinder is powered on, the chuck retracts, the O-ring jaws close, the third cylinder retracts, and the seventh L-shaped plate moves in the positive Z-axis direction to the initial position, that is, directly above the O-ring sleeve rod, until the positive Z-axis magnetic induction switch on the third cylinder receives a signal.
[0054] Step 3: The robot grabs the worm and places it on the worm synthesis pre-swing tooling. The fifth cylinder extends, driving the entire tenth vertical plate to move in the negative Y-axis direction until the O-ring is sleeved under the worm. The Y-axis negative end magnetic induction switch of the fifth cylinder is energized. The sixth cylinder retracts, and the twelfth bottom plate and the sleeved rod mechanism installed thereon move in the positive Z-axis direction as a whole until the sleeved rod touches the circular bottom of the worm. At this time, due to the hard limit at the bottom of the worm, the sleeved rod stops moving. The twelfth bottom plate, the eleventh flat plate, and the ring sleeve continue to compress the spring and move in the positive Z-axis direction. The upper surface of the collar pushes the O-ring from the sleeved rod to the annular groove of the worm. After the O-ring enters the groove, the Z-axis positive end magnetic induction switch of cylinder 6 is energized. The sixth cylinder extends, and the twelfth bottom plate and the sleeved rod mechanism installed thereon move downward to the initial position, that is, the twelfth bottom plate is in full contact with the upper support surface of the thirteenth L-shaped plate. The Z-axis negative end magnetic induction switch of the sixth cylinder is energized. The fifth cylinder retracts, driving the entire tenth vertical plate to move backward to the initial position. The Y-axis positive end magnetic induction switch of the fifth cylinder is energized. The robot grabs the worm with the synthesized O-ring to the next station, and returns to the initial position to grab the next worm to be synthesized with the O-ring and place it on the worm synthesis pre-swing tooling, and continues to start the next synthesis cycle of the worm and the O-ring.
[0055] In addition to the above embodiments, the present utility model can also have other embodiments. All technical solutions using equivalent replacements or equivalent transformations fall within the protection scope required by the present utility model.
