DETAILED DESCRIPTION

[0019] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0020] The embodiments of the application are described in detail below with reference to the accompanying drawings.

[0021] As Figures 1-7As shown, this embodiment of the invention provides an industrial robotic arm for transporting aluminum materials, including: a housing 1, a first rotating base 2, a mounting sleeve 3, and a movable plate 4. The first rotating base 2 is rotatably mounted on the top of the housing 1. A connecting arm 202 is movably mounted on the top of the first rotating base 2. A connecting arm 204 is movably mounted on the top of the connecting arm 202 via a movable section 203. A flange 301 is movably mounted on one end of the connecting arm 204. A mounting bracket 205 is fixedly mounted on the rear end face of the first rotating base 2. A second connecting bracket 207 is fixedly mounted on the outer side of the movable section 203. The second connecting bracket 207 and the mounting bracket 205 are movably connected via a first telescopic rod 206. The second connecting bracket 207 and the flange 301 are connected via a second telescopic rod 206. The rod 208 is movably installed. The bottom end of the flange 301 is fixedly installed with an installation sleeve 3. The top of the installation sleeve 3 is rotatably installed with a second movable sleeve 302. The bottom of the second movable sleeve 302 is fixedly installed with an installation plate 308. The outside of the installation plate 308 is movably installed with a movable rod 402. The bottom inside of the installation plate 308 is movably installed with a movable plate 4. The movable plate 4 and the movable rod 402 are movably connected by a flipping rod 401. The bottom of the chassis 1 is fixedly installed with a base 101. The inside of the chassis 1 is fixedly installed with a first motor 102. The output end of the first motor 102 is fixedly installed with a transmission gear 103. The bottom of the first rotating seat 2 is fixedly installed with a driven gear 104. The driven gear 104 and the transmission gear 103 mesh with each other.

[0022] The robot arm is started by a first motor 102 fixedly installed inside the housing 1. The output shaft of the first motor 102 drives the transmission gear 103 at its end to rotate. Since the transmission gear 103 meshes with the driven gear 104 fixedly installed at the bottom of the first rotating base 2, the rotational motion of the first motor 102 is converted into the horizontal rotation of the first rotating base 2 relative to the housing 1. This process provides the entire robotic arm with a wide range of horizontal working angles, which is the basis for its ability to perform large-scale operations.

[0023] Reference Figures 2-3 The first rotating seat 2 and the connecting boom 202 are movably installed through the first connecting frame 201.

The second telescopic rod 208 and the flange 301 are movably connected through the first connecting seat 210. The connecting arm 204 and the flange 301 are movably connected through the second rotating seat 211.

[0024] The first telescopic rod 206 is movably connected, and the second connecting frame 207 is movably connected to the flange 301 through the second telescopic rod 208. When the first telescopic rod 206 and the second telescopic rod 208 move in coordination, they will push or pull the second connecting frame 207 and the movable section 203, thereby precisely controlling the posture and end position of the connecting arm 204.

[0025] With reference to Figures 4-6 , the inside of the mounting sleeve 3 is fixedly mounted with a second motor 303, the output end of the second motor 303 is fixedly connected with a second movable sleeve 302, the inside of the second movable sleeve 302 is movably mounted with a rack 306, the outside of the second movable sleeve 302 is fixedly mounted with a third motor 304, the output end of the third motor 304 is fixedly mounted with a rotating gear 307, the rotating gear 307 and the rack 306 are mutually engaged, and the outside of the second movable sleeve 302 is fixedly mounted with a protective cover 305 matched with the rotating gear 307.

[0026] The rotating movement of the rotating gear 307 is converted into the precise linear up-and-down movement of the rack 306 through the mutual engagement of the rotating gear 307 and the rack 306 movably mounted in the inside of the second movable sleeve 302, the bottom end of the rack 306 is fixedly connected with the movable disc 4, thus the linear movement of the rack 306 directly drives the movable disc 4 to move up and down, the movable disc 4 and the two movable rods 402 are movably connected through the turnover rods 401, when the movable disc 4 moves downward, it will push the lower ends of the two movable rods 402 to swing outward through the turnover rods 401; conversely, when the movable disc 4 moves upward, it will pull the lower ends of the movable rods 402 to fold inward, the anti-skid lines on the inside of the anti-skid blocks 406 can effectively increase the friction force, ensuring firm and reliable clamping of the aluminum material and preventing slipping.

[0027] With reference to Figures 5-7 , the bottom end of the rack 306 is fixedly connected with the movable disc 4, the movable rods 402 and the mounting disc 308 are movably connected through the second connecting seats 403, the movable rods 402 and the turnover rods 401 are movably mounted through the mounting shafts 404, the bottom of the movable rods 402 is fixedly mounted with the clamping rods 405, the bottom of the clamping rods 405 is fixedly mounted with the anti-skid blocks 406, and the inside of the anti-skid blocks 406 is provided with anti-skid lines.

[0028] The movable disc 4 and the two movable rods 402 are movably connected through the turnover rods 401. When the movable disc 4 moves downward, it will push the lower ends of the two movable rods 402 to swing outward through the turnover rods 401; conversely, when the movable disc 4 moves upward, it will pull the lower ends of the movable rods 402 to fold inward, the anti-skid lines on the inside of the anti-skid blocks 406 can effectively increase the friction force, ensuring firm and reliable clamping of the aluminum material and preventing slipping.
