Description

Technical Field

[0001] The utility model belongs to the technical field of robot automatic material picking, in particular to a robot automatic material picking device. Background Art

[0002] Robotic automatic picking equipment is an indispensable part of modern automated warehouses and production lines. They use machine vision technology and advanced robotic systems to achieve efficient and accurate material handling and sorting.

[0003] When existing robotic automatic sorting equipment clamps defective or unqualified products, it usually clamps them with claws. This method can easily cause the clamped products to slip and fall off, causing the products to fall. The fallen products can easily collide with intact products, thereby damaging the intact products and causing economic losses. Moreover, after the products fall, they will be transported away along with the good products, resulting in unqualified products in the finished products. Therefore, we propose a robotic automatic picking equipment. Utility Model Content

[0004] The utility model aims to provide a robot automatic picking device, which can clamp a variety of round and flat products by setting a clamping block, specifically, an arc groove is opened at the center of the clamping block, so that it can be used more widely. After the clamping block clamps the product, it will be squeezed, and at the same time, the spring will be squeezed, which can play a certain buffer in the clamping process to avoid damage to the product. At the same time, the spring can make the clamping block close to the product under the elastic effect of the spring, increase the friction, improve the clamping effect, avoid slipping, and make it more stable after clamping, which solves the problem that the existing robot automatic sorting equipment usually uses claws for clamping, which easily causes the clamped product to slip and fall off, thereby causing the product to fall.

[0027] A specific application of this embodiment is:

[0028] When in use, the conveying device 1 conveys the product to the bottom of the clamping assembly 12, and then the visual recognition device 141 visually recognizes the product through the camera 142. The visual recognition device 141 refers to a device that uses machine vision technology to perform image recognition, obtains images through image capture devices such as the camera 142, and then uses algorithms to analyze and process the images to achieve specific functions, such as identifying objects, detecting defects, and navigating. When it is recognized that the product has defects or is unqualified, the robot arm body 11 will be activated to drive the fixed seat 121 to the position of the defective product. When the product is moved to the position, the electric push rod 212 is started to drive the connecting block 124 to move forward, and the fixing frame 241 moves together. Since the side of the inclined plate 231 close to the fixing frame 241 is set as an inclined surface, the fixing frame 241 will push the inclined plate 231 after contacting with the inclined plate 231, so that the two inclined plates 231 are close to each other, and at the same time drive the two moving seats 123 to be close to each other, and the moving seat 123 slides on the sliding rod 126 through the sliding hole 232, and at the same time the spring 261 is stretched, and the moving seat 123 is driven by the connecting shaft 223 and the fixing block 222. The movable connecting plates 122 are moved close to each other. When the clamping block 221 contacts the product, the product will be clamped. Since an arc groove 224 is provided at the center of the clamping block 221, a variety of round and flat products can be clamped, which is more widely applicable. After the clamping block 221 clamps the product, it will be squeezed, and the limit rod 225 will slide in the connecting plate 122, and at the same time, the spring 226 will be squeezed, which can play a certain buffer in the clamping process to avoid damage to the product. At the same time, the elasticity of the spring 226 can make the clamping block 221 close to the product to increase friction. The friction improves the clamping effect, avoids slipping, and makes the clamping more stable. Then the robot arm body 11 moves the clamped product to the placement plate 13, and then starts the electric push rod 212 to drive the connecting block 124 to move backward. The moving seat 123 is canceled and reset under the elastic action of the spring 261. Then the two connecting plates 122 drive the two clamping blocks 221 away from each other, releasing the clamping of the product, and the product falls on the placement plate 13 for collection. Then the robot arm body 11 moves the clamping assembly 12 to the product position again for identification and picking.
