Description

Technical Field

[0001] The utility model relates to the technical field of adsorption components, in particular to an adsorption component for an industrial robot. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. With the continuous development of society, the mechanical field has also begun intelligent production operations. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. When industrial robots are working, they need to use adsorption components to adsorb and transport some objects.

[0003] After searching, the Chinese patent announcement number CN221066346U discloses an adsorption component for an industrial robot. The patent can deliver airflow to the air supply box through the air intake box and the bellows, and then the airflow is discharged through the first pipe, the telescopic hose and the second pipe. When the adsorption component adsorbs an object, it can blow air on the surface of the object to remove the falling dust. Moreover, through the setting of the upper ring plate, the compression spring and the lower ring plate, when adsorbing the object, after the air outlet strip contacts the object, the adsorption work is performed by continuing to move the suction plate downward. The compression spring can be compressed to drive the telescopic hose to contract, which will not affect the adsorption work of the object, thereby improving the practicality of the adsorption component.

[0004] The above patent blows air toward the surface of an object through the air outlet strips, thereby removing dust from the surface of the object. However, as the distance from the air outlet strips increases, the wind force gradually weakens, resulting in incomplete cleaning of areas far from the air outlet strips. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1-Figure 5 As shown, an adsorption assembly for an industrial robot includes a mounting frame 1, which is an inverted U-shape. A suction plate 2 is fixedly connected to the bottom of the mounting frame 1, and a plurality of suction cups 3 arranged at equal intervals are fixedly connected to the bottom of the suction plate 2. A negative pressure chamber 405 is opened in the suction plate 2, and the suction cups 3 are connected to the negative pressure chamber 405.

[0026] A negative pressure component is provided on the top of the suction plate 2, which is used to generate negative pressure in the negative pressure chamber 405 to adsorb the workpiece. The negative pressure component includes a piston cylinder 401 fixedly connected between the mounting frame 1 and the suction plate 2. An air extraction port 406 is provided in the suction plate 2 to connect the piston cylinder 401 with the negative pressure chamber 405. The top of the mounting frame 1 is fixedly connected to a cylinder 402, and the piston rod end of the cylinder 402 extends into the piston cylinder 401 and is fixedly connected to a lifting plate 403. The lifting plate 403 is moved along the inner wall of the piston cylinder 401. The lifting plate 403 slides downward, and the bottom of the lifting plate 403 is fixedly connected to a rubber piston 404. The lifting plate 403 in the piston cylinder 401 is driven by the control cylinder 402 to drive the rubber piston 404 to move upward, and the air in the negative pressure chamber 405 is extracted to generate negative pressure in the negative pressure chamber 405, so that the suction cup 3 adsorbs the workpiece. The rear side of the suction plate 2 is provided with an air vent connected to the negative pressure chamber 405, and an electromagnetic valve is provided in the air vent. When the workpiece needs to be loosened, the control valve in the air vent is opened to achieve pressure relief.

[0027] An air inlet 502 is provided at the top of the suction plate 2, and the air inlet 502 is connected to the negative pressure chamber 405. Solenoid valves are provided in the air exhaust port 406 and the air inlet 502. An air supply component is provided on the top of the suction plate 2, and the air supply component is used to blow air into the negative pressure chamber 405 through the air inlet 502. The air supply component includes a hair dryer 501, and the hair dryer 501 is bolted to the top of the suction plate 2. The air outlet of the hair dryer 501 is connected to the air inlet 502. Air is blown into the negative pressure chamber 405 through the hair dryer 501, so that the wind is blown out from the suction cup 3, thereby blowing the debris on the workpiece under the suction cup 3 to the surroundings of the suction cup 3, so as to avoid affecting the adsorption effect.

[0028] A trigger assembly is provided at the top of the suction plate 2, which is used to control the opening and closing of the air supply assembly. The trigger assembly includes a slide rod 503 slidably connected to the suction plate 2, and the bottom end of the slide rod 503 extends out of the suction plate 2. The initial position of the lower end of the slide rod 503 is lower than the position of the suction cup 3, so that when the suction plate 2 moves downward, the slide rod 503 first abuts against the workpiece, and the top of the slide rod 503 extends out of the suction plate 2 and is welded with a limit plate 504. A spring 505 is connected between the limit plate 504 and the suction plate 2, and the spring 505 is wound around the outer periphery of the slide rod 503. An extension plate 506 is fixedly connected to one side of the limit plate 504. A first proximity switch 507 and a second proximity switch 508 are provided on the inner wall of the mounting frame 1, and the extension plate 506 is located between the first proximity switch 507 and the second proximity switch 508.

[0029] Working principle: When in use, the adsorption component is installed on the industrial robot through the mounting bracket 1. When the workpiece needs to be adsorbed, the suction plate 2 is first moved to the top of the workpiece by the industrial robot, and the mounting bracket 1 drives the suction plate 2 to move in the direction close to the workpiece. The slide bar 503 first contacts the workpiece, and then the slide bar 503 drives the limit plate 504 to move upward along the suction plate 2, and the limit plate 504 drives the extension plate 506 to move. When the distance between the extension plate 506 and the first proximity switch 507 reaches a certain value, the solenoid valve in the air inlet 502 is opened. At the same time, the blower 501 is started, and the air is blown to the negative electrode through the air inlet 502. Air is blown in the pressure chamber 405 so that the air is blown out from the suction cup 3, thereby blowing the debris on the workpiece below the suction cup 3 to the surroundings of the suction cup 3 to avoid affecting the adsorption effect. When the distance between the extension plate 506 and the second proximity switch 508 reaches a certain value, the blower 501 is turned off, the solenoid valve in the air inlet 502 is closed, and the suction plate 2 continues to move downward until the suction cup 3 abuts the workpiece. The lifting plate 403 in the piston cylinder 401 is driven by the control cylinder 402 to drive the rubber piston 404 to move upward, and the air in the negative pressure chamber 405 is extracted to generate negative pressure in the negative pressure chamber 405, so that the suction cup 3 adsorbs the workpiece.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
