Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a robotic arm with automatic box packing function. Background Technology

[0002] A robotic arm is an automatic operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects or operate tools according to a fixed program. It mainly consists of three parts: an actuator, a drive mechanism, and a control system. In automatic packing equipment, the automatic robotic arm is an indispensable functional mechanism.

[0003] However, when using automated packing robots for packing, the gripper length and force-bearing area are limited. When encountering tall objects, the gripper cannot hold the objects stably. Replacing the gripper with a larger one is cumbersome, time-consuming, and labor-intensive. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robotic arm with an automatic packing function. The robotic arm is equipped with an extended claw, which has multiple limiting grooves. With the cooperation of a slider, a limiting block, and a spring, the extension length of the extended claw can be adjusted, enabling it to clamp objects of different heights.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A robotic arm with automatic packing function includes a robotic arm body. A mounting plate is provided at the shaft end of the robotic arm body. An opening is provided at the upper end of the mounting plate. A rotating shaft is rotatably connected to the lower end of the mounting plate. A gear is mounted on the rotating shaft.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A robotic arm with automatic packing function includes a robotic arm body 1, which is existing technology and will not be described in detail here. The robotic arm body 1 has a mounting plate 2 at the shaft end. The upper end of the mounting plate 2 has an opening 3. The lower end of the mounting plate 2 is rotatably connected to a rotating shaft 4. A gear 5 is mounted on the rotating shaft 4. The lower end of the mounting plate 2 is fixedly connected to four fixing plates 6. A fixing rod 7 is fixedly connected between each pair of mating fixing plates 6. Two moving blocks 8 are slidably connected to each of the two fixing rods 7. A rack 9 is fixedly connected to one end of each of the two moving blocks 8. The two moving blocks 8 are not adjacent. Both racks 9 mesh with the gear 5. The upper end of the mounting plate 2 is provided with a drive mechanism for driving one of the moving blocks 8 to move.

[0023] The driving mechanism is an electric push rod 10 mounted on the upper end of the mounting plate 2. An L-shaped rod 11 is fixedly connected to the telescopic end of the electric push rod 10. One end of the L-shaped rod 11 passes through the through-hole 3 and is fixedly connected to one of the moving blocks 8. By telescoping the electric push rod 10, the L-shaped rod 11 moves the corresponding moving block 8, which in turn moves the corresponding rack 9. Since the gear 5 and the rack 9 mesh, the gear 5 rotates as the rack 9 moves, which in turn moves the other rack 9. The lower ends of each pair of cooperating moving blocks 8 are fixedly connected to a strip plate 12. The lower ends of the two strip plates 12 are fixedly connected to a gripper 13. Through the cooperation of the gear 5 and the rack 9, the two grippers 13 can move relative to each other or move away from each other to clamp or release the object. The distance between the two grippers 13 can be adjusted so that objects of different widths can be clamped.

[0024] Each of the two grippers 13 has a rectangular groove 14 on its opposite side, and an extension claw 15 is inserted into each of the two rectangular grooves 14. A sliding groove 16 is formed on one inner wall of each of the two rectangular grooves 14. Each sliding groove 16 is equipped with a limiting mechanism to limit the corresponding extension claw 15. The two limiting mechanisms include two sliders 17, which are slidably connected to the inner wall of the corresponding sliding groove 16. One end of each slider 17 is fixedly connected to a limiting block 18. Each of the two extension claws 15 has multiple limiting grooves 19 on one side that cooperate with the corresponding limiting blocks 18. By using the limiting blocks 18… By inserting the two extension claws 15 into different limiting slots 19, the positions of the two extension claws 15 in the corresponding rectangular slots 14 can be adjusted, thereby adjusting the extension length of the two extension claws 15 and increasing the force-bearing area of ​​the two grippers 13, so that objects of different heights can be clamped. The other ends of the two sliders 17 are elastically connected to the inner wall of the corresponding slide groove 16 through springs 20. The other ends of the two sliders 17 are fixedly connected to pull rods 21. The other ends of the two pull rods 21 pass through the corresponding grippers 13 and extend to the outside. The ends of the two pull rods 21 located on the outside are fixedly connected to pull rings.

[0025] In this invention, when the robotic arm 1 encounters a tall object, it pulls two levers 21 to move two sliders 17. The movement of the two sliders 17 moves the corresponding limiting blocks 18, causing the two limiting blocks 18 to leave the corresponding limiting grooves 19. Without releasing the levers, it moves two extension claws 15 to the appropriate position. Then, it releases the two levers 21. Under the elastic action of the two springs 20, the two sliders 17 return to their original positions, causing the two limiting blocks 18 to engage in the corresponding limiting grooves 19. This limits the two extension claws 15. By adjusting the extension length of the two extension claws 15, the force-bearing area of ​​the two grippers 13 can be adjusted, thus enabling the gripping of objects of different heights.

[0026] After adjustment, the robotic arm body 1 is activated, moving the two grippers 13 to the clamping position. Then, the electric push rod 10 is activated. After the electric push rod 10 is activated, it moves the corresponding moving block 8 via the L-shaped rod 11, which in turn moves the corresponding rack 9. Since the gear 5 and the rack 9 mesh, the gear 5 rotates as the rack 9 moves, which in turn moves the other meshing rack 9. The movement of the two racks 9 causes each pair of mating moving blocks 8 to move relative to the corresponding strip plate 12, thereby moving the two grippers... The jaws 13 move relative to each other to clamp the object. After clamping the object and moving it into the box, the electric push rod 10 is activated, causing its extension end to return to its original position. This causes the two racks 9 to move back to their original positions. At this time, the two jaws 13 move in opposite directions, releasing the object for packing. The above operation can be repeated to automatically pack multiple objects. Through the cooperation of the gears 5 and racks 9, the two jaws 13 can clamp the object for automatic packing. The distance between the two jaws 13 can be adjusted to clamp objects of different widths.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
