[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings: Example

[0017] like Figures 1 to 5As shown, this embodiment discloses an automatic material dispensing and picking device, including a frame 1. A dispensing device 2 and a picking device 3 are fixed on the frame 1. The dispensing device 2 includes a dispensing bearing seat 202 disposed on the frame 1 and rotatably connected to the frame 1. A dispensing column 201 is also fixed on the frame 1. The dispensing column 201 passes through the dispensing bearing seat 202 and is rotatably connected to the dispensing bearing seat 202. The dispensing bearing seat 202 is driven to rotate by a dispensing rotary motor 204. A dispensing table 206 is fixed above the dispensing bearing seat 202. Multiple dispensing surfaces are evenly fixed on the dispensing table 206. Positioning device 207 includes multiple positioning rods 208 fixed on the distributing table 206. A distributing mounting plate 210 is also fixed above the distributing column 201. Guide pulleys 211 and conveyor pulleys 212 are respectively arranged on both sides of the distributing mounting plate 210. The guide pulleys 211 are connected to the conveyor pulleys 212 via a synchronous belt 214. The conveyor pulleys 212 are driven to rotate by the distributing motor 213. A slider is also fixed on the synchronous belt 214, and a distributing push plate 217 is fixed on the slider. The material handling device 3 includes components mounted on the frame 1 and rotating with the frame 1. The material-retrieving bearing seat 301 is dynamically connected and driven to rotate by the material-retrieving rotary motor 302. A vertical plate 305 is fixed on the material-retrieving bearing seat 301, and a vertical rod 306 is vertically fixed on the vertical plate 305. A first rotating shaft 307 is also provided on the vertical plate 305, and a large arm 311 is fixed on the first rotating shaft 307. The first rotating shaft 307 is driven to rotate by the first motor 310. A second rotating shaft 312 is also provided at the end of the large arm 311, and a limiting rod 313 is provided on the second rotating shaft 312 and rotatably connected to it. Rod 313 is connected to upright rod 306 via connecting rod 314. Second rotating shaft 312 is driven to rotate by second motor 318. A forearm 315 is also fixed on the second rotating shaft 312. A positioning shaft 316 is provided at the end of the forearm 315 and is rotatably connected to the forearm 315. A positioning plate 322 is provided on the positioning shaft 316 and is rotatably connected to the positioning shaft 316. The positioning plate 322 is connected to the limiting rod 313 via positioning pull rod 317. A material picking plate 324 is also fixed below the positioning plate 322. Multiple strong magnets 325 are evenly fixed at the bottom of the material picking plate 324.Products with iron cores are placed on various positioning devices 207, and positioned by corresponding positioning rods 208. After the products are stacked on the positioning devices 207, the dispensing motor 213 drives the synchronous belt 214 to rotate, and the dispensing slider 215 moves with the synchronous belt 214. The dispensing push plate 217 passes through one of the clearance slots 209 of the dispensing table 206 and contacts the product at the position of the positioning device 207, pushing the product upward. After the top layer of products reaches the designated position, the strong magnet 325 under the picking plate 324 contacts the iron core of the product. Due to the attraction of the strong magnet 325 to the iron core, the product is fixed under the picking plate 324. After the product is attracted and fixed, the cylinder 323 is started, and the piston rod on the cylinder 323 shortens. As the material-receiving plate 324 rises, the product rises with it. Once the product reaches above the positioning device 207, the first motor 310 drives the upper arm 311 to rotate around the first rotating axis 307, and the second motor 318 drives the lower arm 315 to rotate around the second rotating axis 312. Since the upright 306, upper arm 311, limiting rod 313, and connecting rod 314 form a parallelogram structure, and the upright 306 is fixed to the upright plate 305, the rotation of the upper arm 311 allows the limiting rod 313 to move upwards in the vertical plane. Furthermore, the lower arm 315, limiting rod 313, positioning plate 322, and positioning rod 317 also form a parallelogram structure. The lower arm 315 rotates around the upper arm 311 around the second rotating axis 312. When the rotating shaft 312 rotates, the positioning plate 322 moves vertically, enabling the product to move smoothly in the vertical plane. The picking-up bearing seat 301 rotates via the picking-up rotary motor 302, and the product rotates around the picking-up bearing seat 301. After the product is moved to the designated position, the cylinder 323 is activated, the piston rod on the cylinder 323 extends, and the scraper blade 326 descends. Upon contact with the product, the scraper blade 326 pushes the product away from the strong magnet 325. After the strong magnet 325 separates from the product, the picking plate 324 returns to its initial position, and the synchronous belt 214 rotates again via the distributing motor 213. The topmost product on the positioning device 207 is then picked up and supplied to the processing machine. This cycle repeats. When one positioning device... After all the products on position 207 have been grabbed, the distributing motor 213 drives the synchronous belt 214 to rotate in the opposite direction. The distributing push plate 217 moves to below the distributing table 206. The distributing rotary motor 204 drives the distributing bearing seat 202 to rotate at a certain angle. Another positioning device 207, which is full of products, reaches directly above the distributing push plate 217. The distributing push plate 217 pushes the products again for the strong magnet 325 to grab. This process is repeated. This device can place a large number of products on multiple positioning devices 207 at once. When the products on one positioning device 207 are all grabbed, the products on another positioning device 207 are moved to a designated position for the strong magnet 325 to grab again. There is no need to stop the machine to add products, which greatly improves production efficiency.

[0018] Among them, a ring-shaped material distribution rack 203 is fixed on the material distribution bearing seat 202, and a material distribution gear 205 is fixed at the output end of the material distribution rotary motor 204. The material distribution gear 205 meshes with the material distribution rack 203.

[0019] Among them, the material distribution table 206 at the position of the positioning device 207 is provided with a clearance groove 209 that penetrates through the material distribution table 206.

[0020] Among them, a circular material picking rack 303 is fixed on the material picking bearing seat 301, and a material picking gear 304 is fixed at the output end of the material picking rotary motor 302. The material picking gear 304 meshes with the material picking rack 303.

[0021] The first rotating shaft 307 is fixed with a first worm gear 308, and the output end of the first motor 310 is fixed with a first worm 309. The first worm gear 308 meshes with the first worm 309.

[0022] Among them, a cylinder 323 is fixed on the positioning plate 322, and a scraper blade 326 is fixed at the end of the piston rod of the cylinder 323. A strong magnet 325 passes through the scraper blade 326 and is slidably connected to the scraper blade 326. Example

Based on the structure and principle of embodiment 1, this embodiment also has a material dispensing slide rail 216 fixed on the material dispensing mounting plate 210, and the material dispensing slider 215 is slidably connected to the material dispensing slide rail 216.

A second worm wheel 321 is fixed on the second rotating shaft 312, and the second worm 320 meshes with the second worm wheel 321. By positioning the second motor 318 above the picking bearing seat 301 and installing it close to the first rotating shaft 307, the load on the first motor 310 is reduced.
