[0015] 2. The present invention sets a guide unit, and the power supply stops providing power to the electromagnetic plate, so that the magnetic block 1 and the magnetic block 2 are not adsorbed by the electromagnetic plate, and the middle guide rail and the bottom guide rail slide downward to form a track to facilitate the downward sliding of the rocker arm of the internal combustion engine. At the same time, the air pump 2 introduces air into the outer guide rail, and part of the air flow flows out through the air outlet 1 to form a high-pressure air flow layer, so that the rocker arm of the internal combustion engine placed on the outer track slides downward, and does not produce high-friction contact with the outer guide rail, the middle guide rail and the inner guide rail, thereby avoiding friction to damage the outer wall of the rocker arm of the internal combustion engine.

This method does not involve contact with other media and will not introduce impurities or pollutants, thereby ensuring the cleanliness of the rocker arm. The micro motor will drive the rotating arm to rotate outward, thereby facilitating the internal combustion engine rocker arm to enter the clamping arm. After entering, the rotating arm will rotate inward, and further spray air through the air outlet groove 2, thereby controlling the suspension of the internal combustion engine rocker arm.
[0017] 4.

When the internal combustion engine rocker arm is about to stop moving, the air pump 1 will also allow gas to enter through the air pipe 3 and the air inlet on the side block, and flow out from the air outlet block. The impact force of the airflow will offset the inertial force, thereby preventing the inertial force from driving the internal combustion engine rocker arm to fly out of the clamping unit.
[0018] 5. The present invention sets a protection unit. During the processing, if any foreign matter flies in the factory, it will block the air outlet block, thereby making the anti-inertia unit invalid. The sliding block will rotate along with the movement of the internal combustion engine rocker arm by the clamping unit, so that the collecting net is always under the internal combustion engine rocker arm. If the monitor 2 in the clamping unit cannot detect the internal combustion engine rocker arm, the servo motor 2 will drive the rotating shaft 1 and the supporting plate 1 to rotate, so that the collecting net is in a horizontal state, thereby protecting the internal combustion engine rocker arm from falling to the ground.

Then the moving device 10 will drive the entire robot arm to move, thereby driving the internal combustion engine rocker arm to move to the processing equipment. If the space is limited, it will be transferred through the guide unit 5. During the movement, the anti-inertia unit 8 and the protection unit 9 will protect the internal combustion engine rocker arm.
[0034] The inner wall of the placement table 1 is provided with an inner plate 11, and the outer surface of the inner plate 11 is evenly provided with a damping spring 12, and the damping spring 12 is fixedly connected with a buffer layer 13 at one end away from the inner plate 11, so that the manipulator can reduce the impact force generated by the collision when moving; When the entire robot moves and collides with other machines or objects, the damping spring 12 will absorb part of the impact force, thereby causing the robot arm on the placement table 1 to produce smaller fluctuations.
[0035] The first robotic arm 2, the second robotic arm 3 and the third robotic arm 4 can all achieve independent rotation and extension. The extension and rotation of the above robotic arms adopt the multi-freedom multi-arm under the existing technology, which can achieve stable extension and rotation, and will not be elaborated here.
[0036] like Figure 4 As shown, the guide unit 5 includes a support block 51, a servo motor 52 is arranged on the outer surface of the support block 51, a rotating block 53 is fixedly connected to the output end of the servo motor 52, a power supply 54 is arranged on the outer surface of the rotating block 53, electromagnetic plates 55 are symmetrically arranged on both sides of the rotating block 53, the electromagnetic plates 55 are connected to the power supply 54 through wires 56, and an extension mechanism 57 is fixedly connected to the outer surface of the electromagnetic plates 55; When the clamping unit 6 is used to clamp the internal combustion engine rocker arm, it will drive the internal combustion engine rocker arm to move to various processing equipment. Since the clamping unit 6 and the anti-inertia unit 8 occupy a certain space, if the space of the processing equipment is limited, the internal combustion engine rocker arm cannot be placed in. At this time, the servo motor 52 will drive the rotating block 53 to rotate a certain angle and face the processing equipment.
[0037] When the guide unit 5 is not working, the rotating block 53 and the extending mechanism 57 are facing downward, and the power supply 54 also transmits electrical energy to the electromagnetic plate 55 through the wire 56.

At the same time, the vacuum fan 2 571 will introduce air into the outer guide rail 572, and part of the air flow will flow out through the air outlet 1 577 to form a layer of high-pressure air flow layer, so that the internal combustion engine rocker arm placed on the outer track slides downward, and does not produce high-friction contact with the outer guide rail 572, the middle guide rail 574 and the inner guide rail 576, thereby avoiding friction to cause damage to the outer wall of the internal combustion engine rocker arm. Finally, when the internal combustion engine rocker arm slides to the bottom, the air flow in the bottom air outlet plate 5710 will flow out from the air outlet plate 5710, in the opposite direction of the internal combustion engine rocker arm's downward movement, thereby reducing the speed at which the internal combustion engine rocker arm slides downward, so that it does not produce a large impact force when it enters the processing equipment, thereby avoiding collision and damage.

[0042] If any foreign matter flies in the factory, it will block the air outlet block 884, thereby making the anti-inertia unit 8 ineffective. The sliding block 94 will rotate along with the movement of the internal combustion engine rocker arm by the clamping unit 6, so that the collecting net 99 is always under the internal combustion engine rocker arm. If the monitor 2 610 in the clamping unit 6 cannot detect the internal combustion engine rocker arm, the servo motor 2 96 will drive the rotating shaft 1 97 and the support plate 1 98 to rotate, so that the collecting net 99 is in a horizontal state, thereby protecting the internal combustion engine rocker arm from falling to the ground.
[0043] The bottom of the support rod 91 is fixedly connected to the outer surface of the first mechanical arm 2 .
[0044] The specific workflow is as follows: During operation, when the clamping unit 6 is used to clamp the internal combustion engine rocker arm, the internal combustion engine rocker arm will be driven to move to various processing equipment. If the space of the processing equipment is limited, the internal combustion engine rocker arm cannot be placed in. At this time, the servo motor 52 will drive the rotating block 53 to rotate a certain angle and face the processing equipment. Then the power supply 54 will stop providing power to the electromagnetic plate 55, so that the magnetic block 1 573 and the magnetic block 2 575 are not adsorbed by the electromagnetic plate 55, and the middle guide rail 574 and the bottom guide rail will slide downward to form a track to facilitate the downward sliding of the internal combustion engine rocker arm. The airflow will flow out through the air outlet 577 to form a layer of high-pressure airflow layer, so that the internal combustion engine rocker arm placed on the outer track will slide downward, and the airflow in the bottom air outlet plate 5710 will flow out from the air outlet plate 5710, which is opposite to the direction of the internal combustion engine rocker arm sliding downward, thereby reducing the speed of the internal combustion engine rocker arm sliding downward.
[0045] Embodiment 2, use Figure 1-Figure 11 A robot for machining a rocker arm of an internal combustion engine according to an embodiment of the present invention is described below.
[0046] like Figure 8 As shown in the figure, a manipulator for processing rocker arms of internal combustion engines of the present invention, on the basis of the first embodiment, a clamping unit 6 comprises a second support plate 61, an outer surface of the second support plate 61 is fixedly connected with an air receiving plate 62, an outer surface of the air receiving plate 62 is fixedly connected with an air pipe 63, an end of the air receiving plate 62 away from the air pipe 63 is fixedly connected with a clamping arm 64 with an air outlet groove 65 on the outer surface, an end of the clamping arm 64 away from the receiving plate is provided with a micro motor 66, an output end of the micro motor 66 is fixedly connected with a rotating arm 67 with an air outlet groove 68 on the outer surface, the rotating arm 67 and the clamping arm 64 cooperate to discharge air so that the rocker arm of the internal combustion engine is suspended in the air by the airflow, and an outer surface of the clamping arm 64 is fixedly connected with a second air pipe 69; When the first robot arm 2, the second robot arm 3 and the third robot arm 4 drive the overall clamping unit 6 to move to the internal combustion engine rocker arm raw material, the internal combustion engine rocker arm will enter the clamping arm 64, and then the vacuum pump 7 will pass the gas into the clamping arm 64 through the air pipe 63 and flow out from the air outlet groove 65, so that the internal combustion engine rocker arm is in a suspended state, avoiding the mechanical damage to the rocker arm surface caused by the traditional clamping method. This method does not involve contact with other media, will not introduce impurities or pollutants, and ensures the cleanliness of the rocker arm. The micro motor 66 will drive the rotating arm 67 to rotate outward, thereby facilitating the internal combustion engine rocker arm to enter the clamping arm 64. After entering, the rotating arm 67 will rotate inward and further spray air through the air outlet groove 68, thereby controlling the suspension of the internal combustion engine rocker arm.
