Problems solved by technology

However, the clamping gripper is a rigid gripper. Although the rigid gripper can realize the function of grabbing the workpiece, it is easy to damage the outer surface of the workpiece, especially for fragile workpieces such as glass plates.
Moreover, the use of clamping grippers has poor grasping balance and stability due to the lack of fit between the clamping part and the outer surface of the workpiece. When the speed of the robot is too fast or the weight of the workpiece is too large during use, it is easy to cause the workpiece to fall. Phenomenon, there are certain security risks, but also cause losses to the enterprise

Embodiment 1

[0027] In this embodiment, two driving devices and two suction units respectively connected to the driving devices are used as an example to describe the following.

[0028] Such as figure 1 with 2 As shown, the robot suction gripper suitable for circular arc curved workpieces of the present invention is installed on the movable end of the robot for grabbing circular arc curved workpieces; the gripper includes a connecting plate 1 connected with the movable end of the robot and a set Two brackets 2 on the connecting plate 1, wherein each bracket 2 is provided with a driving device 3 and a suction unit connected to the driving device 3. The driving device 3 is installed on the bracket 2 and its pushing part 12 is connected with the suction unit, The suction unit is arranged at the bottom of the connecting plate 1, and the suction points between the suction unit and the workpiece 4 are distributed in a circle with the center of the workpiece 4 as a circle.

[0029] The suction unit o...

Embodiment 2

[0035] This embodiment is different from the first embodiment only in that: the suction gripper of the present invention can be provided with a driving device and a suction unit connected to the driving device according to requirements, or three or more driving devices and corresponding to The suction unit connected to the drive device. For the structure of three or more suction units, each bracket in this embodiment is provided with a driving device and a suction unit connected to the driving device. Three or more suction units can simultaneously suck three or more pieces at a time. A curved surface workpiece, thereby improving the practicability, grasping efficiency and production efficiency of the suction gripper. Or, three or more suction units can simultaneously suck a long piece of workpiece with a curved surface. For large or heavy workpieces, this can ensure the balance and stability of the gripper.

[0036] The other structures of this embodiment are consistent with the...

Embodiment 3

[0038] The only difference between this embodiment and the first embodiment is that it does not include the positioning device, the guiding device and the connecting block. One end of the connecting rod of the suction device of this embodiment is connected with the pushing part of the driving device, and the other end is connected with the suction cup. The driving device of this embodiment can directly drive the lifting and lowering of the suction device through the pushing part to realize the grasping of the workpiece with the circular arc surface.

[0039] The other structures of this embodiment are consistent with the first embodiment.

Abstract

The invention provides a suction type robot hand grab applied to circular arc surface workpieces. The suction type robot hand grab is arranged at the movable end of a robot, and is used for grabbing the circular arc surface workpieces. The hand grab comprises a connecting plate connected with the movable end of the robot and more than one bracket arranged on the connecting plate, wherein each bracket is provided with a driving device and a suction unit connected with the driving device; the driving devices are arranged on the brackets, and pushing parts of the driving devices are connected with the suction units; the suction units are arranged at the bottom of the connecting plate; suction points of the suction units and the workpieces are circumferentially distributed in a manner that the centers of the workpieces are centers of circles. The suction type robot hand grab applied to the circular arc surface workpieces is simple and compact in structure, high in universality and applicable to circular arc surface workpieces in different specifications; the workpieces can be stably grabbed in a rapid movement process of the robot, so that the problem about match between the hand grab and the workpieces is effectively solved, the grabbing balance and stability of the hand grab are improved, and production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of intelligent application of industrial robots, and more specifically, to a suction gripper. Background technique [0002] The robot gripper refers to an automatic operating device that can imitate certain motion functions of human hands and arms to grasp, carry objects or operate tools according to a fixed program. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy. [0003] In a variety of robot grippers, the suction gripper is widely used in various palletizing robots because the suction unit can effectively grip workpieces with block structures such as glass and avoid damage to the workpiece. in. However, most of the existing suction grippers can only grip workpieces with flat sur...
