Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to an industrial robot composite gripper. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom robotic devices widely used in industrial fields. They possess the ability to automatically perform tasks, relying on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots can be commanded by humans or operate according to pre-programmed procedures. Modern industrial robots can also act according to principles and guidelines established by artificial intelligence technology. They typically consist of mechanical, sensing, and control components, and are characterized by ease of use and high levels of intelligence. In practical applications, industrial robots often have composite grippers installed on their manipulators to hold, fix, or transfer parts to be processed.

[0003] A search revealed patent application CN202220458455.8, which discloses an industrial robot composite gripper. The gripper includes a robot arm with a mounting frame at its bottom, and an adjustment assembly inside the mounting frame. This industrial robot composite gripper, through a fixing mechanism, activates a servo motor to rotate a disc. A limiting rod causes a moving frame to move downwards under the support of a support plate and a vertical rod. A connecting rod pushes sliding blocks on both sides to move in opposite directions. Supported by the support rod, a rectangular block and a locking block move simultaneously, causing the locking block to disengage from the mounting plate, allowing the mounting plate to be removed downwards, thus completing the disassembly of the gripper. When installing grippers of different specifications, the mounting plate is extended into the mounting box, and the servo motor is activated to rotate in the opposite direction. The locking block then secures the mounting plate again, completing the gripper replacement. This achieves the purpose of easy disassembly and replacement, facilitating the clamping of workpieces of different shapes.

[0004] However, this patent has its shortcomings. The clamping plate in this type of industrial robot composite fixture is a planar structure, which can only be used to clamp planar parts. When it is necessary to clamp and fix round or tubular parts, it is only possible to disassemble the clamping plate and replace it with a suitable clamping component. When it is necessary to process various planar and round parts alternately, it is often necessary to repeatedly change clamping components of different shapes. The applicability of the equipment is poor, and a lot of time is spent changing clamping components during use, which can easily affect processing efficiency.

[0005] To address this, we propose a composite gripper for industrial robots. Utility Model Content

[0011] Optionally, the bottom end of the drive seat is provided with a sliding groove corresponding to the two slides, and the bottom ends of the two slides extend out of the sliding groove, so that the slides can be limited by the sliding groove.

[0012] Optionally, rubber pads are fixedly installed in both clamps and multiple arc-shaped grooves, which is beneficial to the use of this equipment.

[0013] Optionally, L-shaped limiting rods are fixedly installed on both sides of the drive seat, and limiting grooves are provided in both racks.
