Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically to a mechanical gripper capable of storing materials. Background Technology

[0002] In modern industrial production, material handling robots play a crucial role, widely used in various automated production lines. These robots, such as six-axis robots and SCARA robots, are primarily responsible for performing a series of precise physical tasks. These tasks include, but are not limited to, grasping various materials, moving these materials to designated locations, and placing materials in the correct positions. Through these automated operations, material handling robots significantly improve production efficiency, reduce manpower requirements, and, in some hazardous or highly repetitive environments, ensure worker safety.

[0003] In current industrial automation, robotic arm gripper designs are typically limited to holding only one part at a time. This single-part handling method often fails to meet the demands of high-volume and rapid production because it restricts the improvement of production efficiency and the acceleration of operation speed.

[0004] Therefore, it is of great significance to provide a mechanical gripper that can store materials to solve the problems existing in the current technology. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a mechanical gripper that can store materials, so as to solve the problem that the gripper in the current robotic hand can only hold a single part at a time, and the single-part handling cannot meet the high production speed requirements.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mechanical gripper capable of storing materials includes a support frame, the surface of which is provided with a groove, and two sliding blocks are slidably connected inside the groove, with a gripping frame fixedly connected to the bottom end of each of the two sliding blocks;

[0008] Rotating roller four, rotating roller one, rotating roller two, and rotating roller three are rotatably connected from top to bottom on the inner sides of the two clamping frames. Rotating roller three and rotating roller two are connected by a lower rotating belt, and rotating roller one and rotating roller four are connected by an upper rotating belt. Motor three and motor two are mounted on the front of the clamping frame, and motor three and motor two are respectively connected to rotating roller four and rotating roller two for transmission.

[0009] Preferably, a plurality of support rollers are rotatably connected to one side of the lower half of the clamping frame, and the support rollers are in contact with the inner wall of the lower rotating belt.

[0010] Preferably, a side frame is fixedly connected to one side of the upper half of the clamping frame, a movable block is slidably connected inside the side frame, a tensioning roller is rotatably connected to the inner side of the movable block, and the upper rotating belt is rotatably connected to the tensioning roller.

[0011] Preferably, a slide rod is fixedly connected inside the side frame, the slide rod is slidably connected to the movable block, and a spring is sleeved on the surface of the slide rod, the spring being elastically connected to the movable block.

[0012] Preferably, a fixing plate is fixedly connected to the upper part of the clamping frame, an electric telescopic rod is fixedly connected to the outer side of the fixing plate, a clamping plate is fixedly connected to the telescopic end of the electric telescopic rod, and the clamping plate is in contact with the inner side of the upper rotating belt.

[0013] Preferably, the four rotating rollers, one rotating roller, two rotating rollers and three rotating rollers have the same diameter, and the inner sides of the upper rotating belt and the lower rotating belt are both vertical.

[0014] Preferably, there are four support rollers, and the right sides of all four support rollers are in contact with the inner side of the lower rotating belt, and the right sides of the support rollers are kept perpendicular.

[0015] Preferably, side plates are fixedly connected to both sides of the top of the support frame, and a threaded rod is rotatably connected between the two side plates.

[0016] Preferably, the threaded rod includes two opposite threads, and the two threads are respectively threadedly connected to two sliding blocks.

[0017] Preferably, a motor is fixedly connected to one side of the side plate, and the output end of the motor is connected to the threaded rod for transmission.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The gripper of this invention can hold two products at a time. During product gripping, motor one drives a threaded rod to rotate, which in turn causes a sliding block to separate. Then, a robotic arm moves the gripper to the top of the product, positioning it between two lower rotating belts. Motor one then starts, bringing the two lower rotating belts closer together and gripping the product. Motor two then starts, driving the lower rotating belts to rotate via a rotating roller, lifting the product upwards while it is gripped. Motor three then drives the upper rotating belts via a rotating roller, transferring the product between the two upper rotating belts. Finally, an electric telescopic rod moves the gripping plate... The product is further secured, while the two sliding blocks are slightly adjusted to move away from one end. The product is held in place by the clamping plate, and then the lower rotating belt is used to clamp the second product. After clamping the two products, the product is moved, and the lower rotating belt rotates in the opposite direction to release the lower product. Then the clamping plate retracts, and the two conveyor belts relay the transport to release the second product. Compared with existing robotic arms, this invention can clamp two products at a time, realizing product handling and transfer, which greatly improves handling efficiency. The two products can also be stacked and stacked, making the use flexible and diverse, and meeting diverse production needs.
