Description

Technical Field

[0001] This utility model relates to the field of robot gripper technology, specifically to a high-efficiency and stable robot gripper. Background Technology

[0002] A robotic gripper is a mechanical device, typically mounted on the end effector of a robot, used to grasp, hold, and manipulate objects of various shapes, sizes, and materials. It precisely positions and grasps target objects, quickly and accurately completing material handling and loading / unloading tasks, and can adapt to diverse task requirements.

[0003] Chinese utility model patent CN213136777U discloses an improved gripper for industrial robots that facilitates stable gripping. The gripper includes a main frame with a fixed opening at the center of one side. A drive gripper is fixedly connected inside the fixed opening, and a T-shaped groove is formed inside the drive gripper. An electric hydraulic cylinder is fixedly mounted at the bottom of the T-shaped groove, and a transmission block is fixedly mounted at one end of the electric hydraulic cylinder. Connectors are hinged to both sides of the transmission block. The gripper has two matrix grippers, enabling flexible and stable gripping of products of different shapes and specifications. This avoids the drawbacks of traditional grippers that require changing to adapt to different products. The hydraulic cylinder increases power, and the transmission relies on a sector-shaped gear plate, improving the gripping stability. It also features a self-locking function, enhancing adaptability. During use, a vacuum suction cup is used to assist in gripping, providing multiple protections for the gripped product and maximizing gripping stability. This design has high practical value.

[0004] However, when this robotic gripper is in use, if there is a missed clamping or empty clamping, it can easily lead to inaccurate quantity of products in each box. Therefore, a more efficient and stable robotic gripper is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a highly efficient and stable robot gripper with advantages such as automatic replenishment after missed clamping. It solves the problem that common robot grippers often lead to inaccurate product quantities per box when missed or empty clamping occurs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency and stable robot gripper includes a box infeed conveyor, an outfeed conveyor fixedly installed at the output end of the box infeed conveyor, an end-effector fixedly installed at the input end of the outfeed conveyor, a waiting conveyor fixedly installed at the input end of the end-effector, a feeding conveyor fixedly installed at the input end of the waiting conveyor, a replenishment mechanism fixedly installed on one side of the waiting conveyor, and a box packing rotation assembly fixedly installed at the output end of the end-effector.

[0008] The replenishment mechanism includes a replenishment rotating assembly fixedly installed on one side of the waiting conveyor. Both the replenishment rotating assembly and the packing rotating assembly are fixedly equipped with clamping assemblies. The replenishment rotating assembly drives the clamping assemblies to rotate between the waiting conveyor and the packing conveyor.

[0009] Furthermore, the replenishment rotating assembly includes a replenishment base plate, a replenishment upright plate fixedly installed on the top of the replenishment base plate, a replenishment mounting plate fixedly installed on the top of the replenishment upright plate, a replenishment rotating column rotatably installed on the top of the replenishment mounting plate, and a replenishment top plate fixedly installed on the top of the replenishment rotating column.

A clamping rotating shaft is rotatably installed on the bottom of the clamping base plate, a clamping suction cup is fixedly installed on the bottom of the clamping rotating shaft, a clamping motor that drives the clamping rotating shaft to rotate is fixedly installed on the top of the clamping base plate, and a clamping air pipe is fixedly installed on the top of the clamping suction cup.

[0015] Furthermore, the clamping suction cup includes a suction cup base fixedly installed at the bottom of the clamping rotation shaft, two sets of suction heads are fixedly installed at the bottom of the suction cup base, and two detection lenses are fixedly installed on one side of the suction cup base, with three suction heads in one set.

[0016] Compared with the prior art, this utility model provides a highly efficient and stable robot gripper, which has the following beneficial effects:

[0017] 1. This efficient and stable robotic gripper transfers goods from the infeed conveyor to the waiting conveyor. During loading, the goods are transferred to the end conveyor for boxing. After boxing, the outgoing conveyor moves the box to the middle section of the outgoing conveyor. When a missing item is found, the replenishment rotating component moves the gripping component to pick up the goods from the waiting conveyor and put them into the box, thus replenishing the missing item. This solves the common problem of inaccurate product quantity in each box when missing or empty items are found in robotic grippers.

[0018] 2. This efficient and stable robotic gripper uses a detection lens on one side of the suction cup base to detect whether the suction head is picking up the goods. If a missed grip occurs, the number of missed grips is recorded for easy replenishment in the future. Attached Figure Description
