[0002] A manipulator is an automatic device that can imitate certain movements and functions of human hands and arms and is used to grasp, move objects or operate tools according to a fixed procedure. It is mainly composed of three parts: an actuator, a drive mechanism and a control system.

[0003] Manipulators are used in many transportation industries to achieve high-precision and low-manpower material handling. However, when transporting LED screens, ordinary manipulators are mostly open and close, and often generate local stress at the grabbing position of the LED screen during grabbing, causing damage to the LED screen. Existing LED screens are getting thinner and thinner, so when using manipulators to transport LED screens, the local stress generated by the manipulators can easily crush the LED screens. At the same time, when today's manipulators transport LED screens, they usually transport them in a single-piece mode. The single-piece transport method is the main form at the current stage and has low efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0018] The utility model proposes a suction cup manipulator for transporting LED screens, including a fan-shaped plate 1, which is set to be a quarter circle, and at least two vacuum adsorption devices 2 are installed on the arc edge of the fan-shaped plate 1, and the vacuum adsorption device 2 is used to adsorb the LED screen, thereby realizing the transportation function of the LED screen. The center of the circle of the fan-shaped plate 1 is rotatably connected with a mounting plate 3 through a rotating shaft, and the mounting plate 3 is equidistant from the fan-shaped plate 1. The surface of the mounting plate 3 on the side away from the fan-shaped plate 1 is connected with a driving device 4 through bolts, and the driving device 4 uses a motor, and the driving device 4 is used to drive the fan-shaped plate 1 to rotate.

[0019] The vacuum adsorption device 2 includes a conical suction cup 21, which is made of a flexible material. The suction cup 21 is connected to an air pipe 22, and the end of the air pipe 22 facing away from the suction cup 21 is fixedly connected to the fan-shaped plate 1 by bolts. A vent hole 221 is provided on the side wall of the air pipe 22, and the vent hole 221 is used to connect to the vacuum pump. That is, when it is necessary to grab the LED screen, the suction cup 21 is first pressed against the LED screen, and then the suction cup 21 is sucked into a vacuum state by the vacuum pump, thereby achieving the effect of adsorbing the LED screen. When the suction cup 21 is used for adsorption, the contact area between the suction cup 21 and the LED screen is large, and the stress distribution generated during the transportation is more uniform, further avoiding excessive local stress. When the LED screen needs to be released, it is only necessary to inject air into the suction cup 21 through vacuum to separate the suction cup 21 from the LED screen.

[0020] It should be noted that in the present application, four vacuum adsorption devices 2 are installed on the fan-shaped plate 1, and the four vacuum adsorption devices 2 are arranged at equal angles along the arc direction of the fan-shaped plate 1, but the number of installed vacuum adsorption devices 2 is not limited to four, and the vacuum adsorption devices 2 can be appropriately increased or decreased according to usage requirements.

[0021] A transmission device 5 is installed on the surface of one side of the mounting plate 3 close to the sector plate 1. The transmission device 5 includes a connecting rod 51, one end of which is rotatably connected to the sector plate 1 through a rotating shaft, and the other end of the connecting rod 51 is rotatably connected to a swing rod 52. The end of the swing rod 52 away from the connecting rod 51 is integrally provided with a large gear 521, and the large gear 521 is rotatably connected to the mounting plate 3 through a rotating shaft. The output end of the driving device 4 passes through the mounting plate 3 and is fixedly connected with a small gear 53 to drive the small gear 53 to rotate. The small gear 53 is meshed with the large gear 521, thereby driving the large gear 521 to rotate, and further the swing rod 52 and the connecting rod 51 drive the sector plate 1 to rotate.

[0022] A top column 6 is also passed through the rocker arm 52, and the top column 6 can slide relative to the rocker arm 52. The axis of the top column 6 is arranged perpendicular to the rocker arm 52. A circular slide groove is also provided on the surface of one side of the mounting plate 3 close to the fan-shaped plate 1. The circular slide groove is coaxially arranged with the large gear 521, and one end of the top column 6 is against the circular slide groove.

[0023] Four pits are provided in the circular slide groove corresponding to the four vacuum adsorption devices 2. The diameter of the pits is set to be the same as the diameter of one end of the top column 6 close to the mounting plate 3, and the end of the top column 6 close to the mounting plate 3 is set to be circular. A photoelectric sensor 7 is also fixedly connected to the surface of the side of the rocker arm 52 facing away from the mounting plate 3. The detection end of the photoelectric sensor 7 is set corresponding to the top column 6, and the end of the top column 6 facing away from the mounting plate 3 is against the detection end of the photoelectric sensor 7. A spring 8 is also provided between the photoelectric sensor 7 and the top column 6. The spring 8 is provided inside the rocker arm 52, and the spring 8 is coaxially sleeved on the top column 6. One end of the spring 8 is against the outward edge of the top column 6, and the other end of the spring 8 is against the photoelectric sensor 7.

[0024] It should be noted that the angle between two adjacent pits is set to 30 degrees. The output end of the photoelectric sensor 7 is electrically connected to the control end of the driving device 4 to output a control signal to the driving device 4, and the driving device 4 responds accordingly based on the control signal.

[0025] When the driving device 4 drives the rocker arm 52 to rotate, the top column 6 will rotate accordingly. When the top column 6 slides into the pit, the elastic force of the spring 8 will push one end of the top column 6 into the pit, and then the other end of the top column 6 will be separated from the detection end of the photoelectric sensor 7. At this time, the photoelectric sensor 7 will output a control signal to the driving device 4, and the driving device 4 will respond accordingly based on the control signal.

[0026] In summary, the utility model can realize the single transfer of four LED screens by installing four vacuum adsorption devices 2 on the fan-shaped plate 1, thereby improving the transfer efficiency of the manipulator. By utilizing the cooperation of the vacuum suction cup 21 and the air pipe 22, the LED screen can be adsorbed, thereby increasing the contact area between the suction cup 21 and the LED screen, so that the stress generated during adsorption can be evenly dispersed, avoiding the generation of large local stress, and further avoiding the problem that the stress generated by grabbing the LED screen during transportation will cause damage to the LED screen.
