Description

A robotic arm for material handling Technical Field

[0001] This utility model belongs to the field of material handling technology, and in particular relates to a robotic arm for material handling. Background Technology

[0002] Material handling refers to activities conducted within the same location with the primary goal of changing the storage state and spatial position of materials. It involves transporting raw materials from their original storage location to production units, transferring materials along the production line, and finally transporting finished products from the factory to customers or sales locations. Material handling is crucial for improving warehouse operational efficiency and directly impacts production efficiency. In manufacturing companies, logistics managers are typically responsible for the handling of goods into the warehouse, the storage of goods within the warehouse, the movement of goods from storage locations to order sorting areas, and their final arrival at the shipping area for shipment. An efficient material handling process is a vital component of a company's supply chain management, influencing material supply at different stages of production, manufacturing, and logistics. Furthermore, it can eliminate inventory bottlenecks, optimize transportation time, and make it easier for customers to access products, thereby improving customer satisfaction. Material handling is an indispensable part of industrial production. Through reasonable planning, selection of appropriate tools and equipment, and adherence to scientific principles and methods, efficient, safe, and economical material handling can be achieved.

[0003] The existing authorized public account CN218596041U discloses a mechanical device for handling materials. Two pulleys are fixedly connected to the lower end of the base, and a mechanical frame is fixedly connected to the upper end of the base. A connecting plate is fixedly connected to the lower side of the mechanical frame, with a caster wheel at the lower end of the connecting plate and a handrail at the upper end. A lifting device is installed within the mechanical frame, and a transport frame is mounted on the mechanical frame. This material handling device uses a motor as its driving force, ensuring sufficient power for the material to rise and preventing insufficient power. The lifting device raises and lowers the material, and a threaded rod rotates to lift the material, preventing obstruction during movement. However, the transport frame on the aforementioned material handling device is of a fixed size, and its length and width cannot be adjusted. This prevents materials smaller than the transport frame from being placed on it, thus limiting its practical use. Therefore, it is necessary to provide a robotic arm for material handling to solve these problems. Summary of the Invention

A second motor 19 is installed on the left end of the second lead screw 12.

[0024] Preferably, the side plate 1 has seven rows and two columns of mounting holes 2 symmetrically opened. Mounting bolts can be inserted into the mounting holes 2, so that the side plate 1 can be fixedly installed on the wall or mechanical device, thereby realizing the overall installation and fixation of the device.

[0025] Preferably, the top and bottom of the slide rail 3 are in contact with two sets of fixing plates 10 respectively. The top of the top fixing plate 10 is flush with the top of the side plate 1, and the bottom of the bottom fixing plate 10 is flush with the bottom of the side plate 1. The width of the fixing plate 10 is the same as the width of the side plate 1. The side of the sliding sleeve 4 installed on the slide rail 3 is provided with a sliding groove that is compatible with the slide rail 3. The slide rail 3 is in the sliding groove. The two sets of fixing plates 10 play the role of closing the slide rail 3, so that the sliding sleeve 4 can move along the slide rail 3 but cannot detach from the slide rail 3.

[0026] Preferably, the two sets of sliding sleeves 4 are at the same height, the two sides of the lifting block 5 are fixedly connected to the sides of the two sets of sliding sleeves 4, and the first threaded sleeve 6 is fixedly installed inside the fixing hole opened on the lifting block 5, so that the lifting block 5 can move along the first threaded rod 7.

[0027] Preferably, the top of the first lead screw 7 is rotatably connected to a set of top fixing plates 10, and the bottom of the first lead screw 7 passes through a through hole opened on the stabilizing block 8. The stabilizing block 8 is fixedly installed on the lower right side of the side plate 1. The stabilizing block 8 can ensure the installation stability of the first lead screw 7 on the right side of the side plate 1. The first motor 9 is fixedly installed on the bottom of the stabilizing block 8 and is connected to the first lead screw 7. The first motor 9 can rotate in both directions, so the first lead screw 7 can be driven to rotate. When the first lead screw 7 rotates, it will drive the first lead sleeve 6 to move up and down, so that the lifting block 5 drives the two sets of sliding sleeves 4 to move along the two sets of sliding rails 3.

[0028] Preferably, the left side of the mounting plate 11 is fixedly connected to the right side of the two sets of sliding sleeves 4. A sliding groove is provided on the inner side of the mounting plate 11, in which two sets of sliders 14 are symmetrically installed. Both the sliders 14 and the sliding groove are set as T-shaped structures, so that the sliders 14 cannot be disengaged from the sliding groove. The sliders 14 are provided with mounting holes, and the second threaded sleeve 13 is fixedly installed in them. The second threaded rod 12 is installed in the mounting groove. The left end of the second threaded rod 12 passes through the left side of the mounting plate 11 and is connected to the second motor 19 installed on the side of the mounting plate 11. The right end of the second threaded rod 12 is rotatably connected to the right side of the mounting groove, so that the second threaded rod 12 can be driven to rotate in the mounting groove by the second motor 19.

[0029] Preferably, the force-bearing block 18 is configured as a T-shaped structure and fixedly installed in the middle of the inner side of the mounting groove on the side of the mounting plate 11. The force-bearing block 18 has a through hole with the same diameter as the second lead screw 12. The second lead screw 12 passes through the through hole. The force-bearing block 18 can assist the two sets of sliders 14 in transmitting the force from the right side of the two sets of sliders 14 to the overall structure of the mounting plate 11, so that no force is generated between the second threaded sleeve 13 and the second lead screw 12, ensuring that the second lead screw 12 can operate normally. The threaded groove on the second lead screw 12 is symmetrical about the force-bearing block 18. The two sets of second threaded sleeves 13 are symmetrical about the second lead screw 12, and the second motor 19 can drive the second lead screw 12 to rotate in both directions. When the second lead screw 12 rotates, the two sets of second threaded sleeves 13 move closer or further away from each other, thereby driving the two sets of sliders 14 to move closer or further away from each other in the mounting groove.

[0030] Preferably, the width of the movable plate 15 is the same as the width of the slider 14. The side opposite to the two sets of movable plates 15 is the inner side of the two sets of movable plates 15. The clamping plate 16 is fixedly installed on the inner side of the movable plate 15. The height of the clamping plate 16 is greater than that of the movable plate 15. By moving the two sets of movable plates 15 closer and further apart, the two sets of clamping plates 16 can be driven to move. Thus, the material to be transported can be clamped and fixed between the two sets of clamping plates 16 for transport and movement. The clamping plate 16 is set with an arc-shaped structure, so as to better adapt to the shape of the material to be transported. The friction plate 17 is installed on the opposite side of the two sets of clamping plates 16. The friction plate 17 can generate a high friction force with the material to be transported, so as to ensure that the material will not fall off between the two sets of clamping plates 16 during the transport process. The lifting and lowering of the mounting plate 11 can be realized by lifting and lowering the lifting block 5, thereby realizing the lifting and lowering of the material, and thus realizing the transport of the material.
