[0004] In the above patent document, the clamping member is installed on the frame and hinged to the second driving member through the connecting frame, so that the second driving member drives the clamping member to grab the material through the connecting frame. However, the clamping member in the above clamping assembly is directly installed on the mounting frame, resulting in the inability to adjust the distance between the two groups of clamping members. When the volume of the material is large, the clamping force will be insufficient, and when the volume of the material is small, it cannot be effectively grabbed. Therefore, an automatic unpacking and loading clamping device is proposed. Utility Model Content

[0024] In order to further understand the features, technical means, and specific objectives and functions achieved by this application, this application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1-Figure 7 As shown, an automatic unpacking, feeding and clamping device comprises a storage box 1, a robotic arm 2 disposed on the storage box 1, and a clamping mechanism 3 mounted on the robotic arm 2 for grabbing materials;

[0026] The clamping mechanism 3 includes a mounting base 31, two groups of symmetrical fixed brackets 32 are provided at the bottom of the mounting base 31, a mounting plate 33 is fixed to the bottom of the fixed bracket 32, a sliding rod 332 is provided inside the mounting plate 33, two groups of mobile frames 336 are provided on the sliding rod 332, a rotatable mounting shaft 34 is installed on the mobile frame 336, a number of clamping claws 341 for grabbing materials are equidistantly fixed on the mounting shaft 34, a number of fixed frames 342 are also provided on the mounting shaft 34, a first telescopic cylinder 338 for driving the mounting shaft 34 to rotate is hinged on the mobile frame 336, the output end of the first telescopic cylinder 338 is hinged on the fixed frame 342, a two-way telescopic component 334 is also provided on the mounting plate 33, the output end of the two-way telescopic component 334 is hinged to two connecting rods 335, and the end of the connecting rod 335 away from the two-way telescopic component 334 is hinged to the mobile frame 336.

[0027] During use, when the bidirectional telescopic component 334 drives the connecting rod 335 hinged at the output end, the connecting rod 335 drives the two groups of mobile frames 336 to slide along the slide rod 332, so that the two groups of mobile frames 336 can move away from or approach each other, thereby adjusting the distance between the two groups of mobile frames 336. By hingedly connecting the first telescopic cylinder 338 to the mobile frame 336 and hingedly connecting the output end of the first telescopic cylinder 338 to the fixed frame 342, when the first telescopic cylinder 338 is extended and retracted, the mounting shaft 34 is driven to rotate through the fixed frame 342. While the mounting shaft 34 rotates, it drives the clamping claw 341, thereby causing the clamping claw 341 to grab or release the material, so that the clamping device can be adjusted according to the size of the material.

[0028] A slide rail 36 for limiting position is further provided at the bottom of the mounting plate 33 , and a slide groove 337 that can be slidably mounted on the slide rail 36 is provided on the movable frame 336 .

[0029] During use, by fixing the slide rail 36 to the bottom of the mounting plate 33, when the mobile frame 336 moves, the slide groove 337 set on the top of the mobile frame 336 can slide along the slide rail 36, which not only improves the bearing strength of the mobile frame 336, but also prevents the mobile frame 336 from being displaced during movement.

[0030] A plurality of second telescopic cylinders 35 are symmetrically arranged at the bottom of the mounting base 31 , and a push block 351 is fixed to the output end of the second telescopic cylinder 35 .

[0031] During use, multiple sets of second telescopic cylinders 35 are fixed to the bottom of the mounting base 31, and a push block 351 is fixed to the output end of the second telescopic cylinder 35, so that the second telescopic cylinder 35 can drive the push block 351 to move longitudinally, so that the push block 351 can remove the outer packaging of the material from the clamping claw 341, thereby preventing the outer packaging from being entangled on the clamping claw 341 after the material is unpacked.

[0032] A frame 13 is fixed on the storage box 1. A second servo motor 14 is provided inside the frame 13. A cutter head 15 for unpacking is installed at the output end of the second servo motor 14.

[0033] During use, the cutter disc 15 is fixed to the output end of the second servo motor 14, so that the second servo motor 14 drives the cutter disc 15 to rotate. When the material is placed on the top of the frame 13, the robotic arm 2 drives the material to move horizontally through the clamping mechanism 3, and then the cutter disc 15 completes the unpacking of the material outer packaging.

[0034] A separation net 17 is provided on the top of the storage box 1 for separating impurities from the material.

[0035] When in use, the separation net 17 is installed on the top of the storage box 1 so that the separation net 17 can screen the material to remove impurities mixed in the material.

[0036] The storage box 1 is provided with a first servo motor 12 , and an output end of the first servo motor 12 is connected to a screw conveying shaft 16 for outputting materials.

[0037] During use, when the first servo motor 12 drives the screw conveying shaft 16 to rotate, the screw conveying shaft 16 can output the material inside the storage box 1, so as to realize automatic material discharge and improve the working efficiency of the storage box 1.

[0038] A robotic arm 2 is provided on the storage box 1 .

[0039] During use, the robotic arm 2 comprises a rotating base, a main arm mounted on the rotating base, and a small arm hinged to the top of the main arm. A motor is affixed to the top of the main arm, driving the small arm to adjust its angle. A mounting bracket is provided at the end of the small arm, away from the main arm, for mounting the clamping mechanism 3. When the clamping mechanism 3 grasps material, the motor drives the small arm to adjust its angle, allowing the small arm, via the mounting bracket, to move the clamping mechanism 3 onto the material, allowing the clamping mechanism 3 to grasp the material.

[0040] The present application drives the forearm to adjust its angle through a motor, so that the forearm drives the clamping mechanism 3 to move onto the material through the mounting frame, and then the first telescopic cylinder 338 drives the mounting shaft 34 to rotate through the fixing frame 342. While the mounting shaft 34 rotates, it drives the clamping claw 341, so that the clamping claw 341 grabs the material, and then the robotic arm 2 places the material on the top of the frame 13 through the clamping mechanism 3. At the same time, the robotic arm 2 drives the material close to the cutter disc 15 through the clamping mechanism 3, so that the cutter disc 15 unpacks the material, and then the robotic arm 2 and the clamping mechanism 3 cooperate to put the material into the storage box 1. When the material is put in, the separation net 17 separates the impurities mixed in the material, and then the first servo motor 12 drives the spiral conveying shaft 16 inside the storage box 1 to rotate, so that the spiral conveying shaft 16 automatically discharges the material inside the storage box 1, thereby completing the use of an automatic unpacking and feeding clamping device.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
