Embodiment 1

[0039] see Figure 1 to Figure 4 , a robot gripper for preventing scratches on the surface of objects, including a fixed plate 1, a claw plate 2 is slidably arranged on the fixed plate 1, a protective air cushion 3 is installed on the claw plate 2, and a circulation groove is also arranged on the claw plate 2 21, the circulation groove 21 penetrates into the protective air cushion 3;

[0040] The claw plate 2 is provided with a flow pipe 5, and the flow pipe 5 is provided with a sealing mechanism 7. The sealing mechanism 7 includes a piston plate 71 installed in the flow pipe 5. The piston plate 71 is provided with a pipeline 73, and the flow pipe 5 is still sliding. A sealing plate 72 is provided, and the sealing plate 72 is slidably arranged on the pipe 73;

[0041] A communication groove 74 is opened on the pipe 73, and the communication groove 74 is used for air intake.

[0042] In this embodiment: since the manipulator is mostly made of a relatively strong alloy, when g...

Embodiment 2

[0048] This embodiment is an explanation made on the basis of Embodiment 1, please refer to Figure 1 to Figure 4 , the piston plate 71 is also provided with a connecting spring 76, and the piston plate 71 is elastically connected between the connecting spring 76 and the sealing plate 72;

[0049] The connection spring 76 is provided on the outer surface of the pipe 73 .

[0050] A gasket block 75 is also arranged on the pipeline 73 , and the gasket block 75 is used for sealing the sealing plate 72 .

[0051] In this embodiment: the piston plate 71 is provided with a connecting spring 76, and the piston plate 71 is elastically connected to the sealing plate 72 through the connecting spring 76, so that when the sealing plate 72 moves towards the piston plate 71 under the action of air pressure When sliding, the connecting spring 76 will be squeezed, so that it accumulates elastic potential energy. When the sealing plate 72 is no longer under the action of air pressure, the con...

Embodiment 3

[0055] This embodiment is an improvement made on the basis of Embodiment 2, please refer to Figure 1 to Figure 4 , the flow pipe 5 is also provided with a filter 6, the filter 6 is used to filter the air entering the flow pipe 5. . In this embodiment: due to the dust in the air, the manipulator is mostly used in environments with poor air quality such as factories. If the air entering the circulation pipe 5 is not filtered, the dust will easily block the circulation groove 21 so that the air cannot enter normally. In the protective air cushion 3, if the particle dust or impurities mixed in the air enter the protective air cushion 3, when the protective air cushion 3 contacts the surface of the article to generate pressure, the dust or impurities are easy to damage the protective air cushion 3.

[0056] Filtration: a filter screen 6 is arranged on the flow pipe 5, and the filter screen 6 can filter the air entering the flow pipe 5, thereby preventing dust and impurities in the...

Abstract

The invention relates to the technical field of robots, and discloses a robot gripper capable of preventing scratches on the surface of an article, which comprises a fixed plate, a claw plate is slidably arranged on the fixed plate, a protective air cushion is mounted on the claw plate, a circulating groove is further formed in the claw plate, and the circulating groove penetrates into the protective air cushion. According to the robot gripper capable of preventing the scratches on the surfaces of the objects, by arranging the protection air cushions, when the claw plates grab the objects, the protection air cushions can protect the surfaces of the objects, the claw plates cannot make direct contact with the surfaces of the objects, and therefore the situation that the surfaces of the objects are scratched in the process when the claw plates directly grab the objects is prevented; by arranging the circulating pipe, air inflation can be conducted in the advancing process of the claw plate, so that additional air inflation equipment does not need to be additionally installed, in addition, by arranging the sealing mechanism in the circulating pipe, the protective air cushion can be sealed in the advancing process of the claw plate, and the phenomenon that the protective air cushion leaks air due to air backflow is prevented.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot gripper for preventing scratches on the surface of objects. Background technique [0002] A robot is a high-precision, multi-input and multi-output, highly nonlinear, and strongly coupled complex system. Because of its unique operational flexibility, it has been widely used in industrial assembly, safety explosion-proof and other fields. [0003] The robot gripper is a complex system with uncertainties such as parameter perturbation, external interference and unmodeled dynamics. Therefore, there are uncertainties in the modeling model of the manipulator. For different tasks, it is necessary to plan the motion trajectory of the joint space of the manipulator, so as to cascade to form the end pose. [0004] However, under the drive of the motor or air pump, the gripper of the traditional robot will touch the surface of the object with a large force. Since the gripper of th...
