Description

Technical Field

[0001] The utility model belongs to the technical field of PPU manipulators, in particular to a PPU manipulator for transporting nuts. Background Art

[0002] The PPU robot, a highly efficient handling device, operates primarily on a cam-linkage mechanism. The following details its working principle for handling nuts: Cam-linkage Mechanism: The PPU robot utilizes a cam and connecting rod combination to achieve a specific motion trajectory. As the cam rotates, the connecting rod drives the handling portion of the robot in linear or rotational motion. Flexible Handling: The robot's flexible motion allows it to easily handle various angles and directions, including picking, moving, and placing nuts. Stable Structure: The PPU robot's stable structure ensures trouble-free operation over extended periods, ensuring accurate and reliable nut handling.

[0003] Currently, PPU manipulators use special suction cups to grasp nuts stably and firmly. However, the suction cups controlled by vacuum pumps are prone to unstable suction when the pump body seals poorly, pipes and valves malfunction, or power failures occur. Because the metal parts of nuts are small in size, they are difficult to find if they fall during transportation, and they may even become stuck in running equipment, posing a safety hazard. Utility Model Content

[0004] The purpose of the present utility model is to provide a PPU manipulator for transporting nuts, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PPU manipulator for transporting nuts, comprising a PPU manipulator body, a mounting plate fixed to the running end of the PPU manipulator body, a suction cup fixed to the lower end of the mounting plate, a transport anti-fall mechanism arranged below the suction cup, the transport anti-fall mechanism comprising a flip anti-fall box and a flip shaft, the flip anti-fall box being arranged below the mounting plate, the flip shaft being fixed to the upper end of the flip anti-fall box, a buffer mechanism being arranged inside the flip anti-fall box, the buffer mechanism comprising a buffer inclined plate, a buffer rotating shaft and a buffer spring, the buffer inclined plate being rotatably connected to the inside of the flip anti-fall box, the buffer rotating shaft being rotatably connected to the rotating groove of the inner wall of the flip anti-fall box, and the buffer spring being arranged below the buffer inclined plate.

[0006] It should be noted in the solution that a flip motor is fixed to one side surface of the mounting plate, and the output end of the flip motor is fixed to one end of the flip shaft.

[0007] It is further worth mentioning that a fixed-point rotating sleeve is embedded and fixed on one side surface of the mounting plate, and the flip shaft is rotatably connected to the fixed-point rotating sleeve.

[0008] It should be further explained that a receiving groove is provided inside the flip anti-fall box, and the suction cups are arranged and distributed above the center of the receiving groove of the flip anti-fall box.

[0009] As a preferred embodiment, one end of the buffer spring is fixed to the bottom of the buffer inclined plate, and the other end of the buffer spring is fixed to the inner bottom wall of the flip anti-fall box.

[0010] As a preferred embodiment, an elastic rubber pad is fixed to the upper portion of the buffer inclined plate, and a vent hole is opened on the upper portion of the mounting plate, and the vent hole is connected to the air drive mechanism of the PPU manipulator body.

[0011] Compared with the prior art, the PPU manipulator for handling nuts provided by the present invention has at least the following beneficial effects:

[0012] Through the set anti-fall mechanism during transportation, the flip anti-fall box can automatically flip under the suction cup during transportation and provide anti-fall insurance, thereby reducing the risk of nuts accidentally falling due to unstable suction of the suction cup and equipment failure in the middle of transportation. Anti-fall protection for small metal parts such as nuts can prevent them from being difficult to find when falling and falling into the equipment, causing hidden dangers of getting stuck.

[0013] Through the buffer mechanism, the rotating buffer ramp cooperates with the buffer spring to buffer the falling nut, and the elastic rubber pad contacts the nut in advance to reduce part of the impact force, providing efficient buffering when the nut falls, which can reduce the trouble of the nut being ejected and the harsh noise caused by strong collision. The buffer ramp is tilted in the flip anti-fall box to guide the collected nuts to one end of the box so that people can take them out accurately. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] See also Figure 1-4 The utility model provides a PPU manipulator for transporting nuts, including a PPU manipulator body 1, a mounting plate 2 is fixed to the running end of the PPU manipulator body 1, a suction cup 3 is fixed to the lower end of the mounting plate 2, and a transport anti-fall mechanism is arranged below the suction cup 3, the transport anti-fall mechanism includes a flip anti-fall box 5 and a flip shaft 6, the flip anti-fall box 5 is arranged below the mounting plate 2, the flip shaft 6 is fixed to the upper end of the flip anti-fall box 5, and a buffer mechanism is arranged inside the flip anti-fall box 5, the buffer mechanism includes a buffer inclined plate 10, a buffer rotating shaft 11 and a buffer spring 13, the buffer inclined plate 10 is rotatably connected to the inside of the flip anti-fall box 5, the buffer rotating shaft 11 is rotatably connected to the rotating groove of the inner wall of the flip anti-fall box 5, and the buffer spring 13 is arranged below the buffer inclined plate 10.

[0021] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that a flip motor 8 is fixed to one side surface of the mounting plate 2 , and an output end of the flip motor 8 is fixed to one end of the flip shaft 6 .

[0022] Further as Figure 3 As shown, it is worth explaining in detail that a fixed-point rotating sleeve 7 is embedded and fixed on one side surface of the mounting plate 2 , and the flip shaft 6 is rotatably connected to the fixed-point rotating sleeve 7 .

[0023] This solution has the following working process: before use, the suction cup 3 of the PPU manipulator body 1 is connected to the negative pressure air drive mechanism, and then uses high-precision sensors and control systems to accurately identify and locate the nut to be transported. The suction cup 3 stably and firmly grasps the nut, and then through mechanical structures such as cam connecting rods, the manipulator realizes multi-axis linkage and flexibly transports the nut to the specified position. After reaching the target position, the manipulator accurately releases the nut to complete the transport task. After the suction cup 3 adsorbs the nut and lifts it to a certain height, the flip motor 8 automatically controls the flip shaft 6 to rotate on the mounting plate 2, so that the flip anti-fall box 5 can automatically flip to the bottom of the suction cup 3 during transportation and provide anti-fall insurance, thereby reducing the risk of accidental nut falling caused by unstable suction of the suction cup 3 and equipment failure in the middle. Anti-fall protection for small metal parts such as nuts can prevent them from being difficult to find when falling and falling into the equipment, causing hidden dangers of getting stuck.

[0024] According to the above working process, it can be seen that the flip anti-fall box 5 can automatically flip to the bottom of the suction cup 3 during transportation and provide an anti-fall insurance function, thereby reducing the risk of the nut accidentally falling due to unstable suction of the suction cup 3 and equipment failure in the middle. Anti-fall protection for small metal parts such as nuts can prevent them from being difficult to find when falling and falling into the equipment, causing hidden dangers of getting stuck.

[0025] Further as Figure 1 、 Figure 2 and Figure 4 As shown, it is worth explaining in detail that a receiving groove 9 is provided inside the flip anti-fall box 5 , and the suction cups 3 are arranged above the center of the receiving groove 9 of the flip anti-fall box 5 .

[0026] Further as Figure 4 As shown, it is worth mentioning that one end of the buffer spring 13 is fixed to the bottom of the buffer inclined plate 10, and the other end of the buffer spring 13 is fixed to the inner bottom wall of the flip anti-fall box 5. When the nut falls into the flip anti-fall box 5, the buffer inclined plate 10 is rotated and connected to the flip anti-fall box 5, and the buffer spring 13 is arranged in the flip anti-fall box 5 to control the flipping amplitude of the buffer inclined plate 10. In this way, the buffer inclined plate 10 in the rotating state cooperates with the buffer spring 13 to buffer the falling nut, and the elastic rubber pad 12 pre-contacts the nut to remove part of the impact force, providing efficient buffering when the nut falls, which can reduce the trouble of the nut being ejected and the harsh noise caused by strong collision. In addition, the buffer inclined plate 10 is tilted in the flip anti-fall box 5 to guide the collected nuts to one end of the box so that people can take them out accurately.

[0028] In summary: the flip anti-fall box 5 can automatically flip to the bottom of the suction cup 3 during transportation and provide anti-fall insurance, thereby reducing the risk of nuts accidentally falling due to unstable suction of the suction cup 3 and equipment failure in the middle. Anti-fall protection for small metal parts such as nuts can prevent them from being difficult to find and falling into the equipment when falling, causing hidden dangers of getting stuck; the rotating buffer ramp 10 cooperates with the buffer spring 13 to buffer the falling nuts, and the elastic rubber pad 12 pre-contacts the nuts to reduce part of the impact force, providing efficient buffering when the nuts fall, which can reduce the trouble of nuts being ejected and strong collisions causing harsh noises. In addition, the buffer ramp 10 is tilted in the flip anti-fall box 5 to guide the collected nuts to one end of the box so that people can take them out accurately.
