Description

Technical Field

[0001] This utility model belongs to the field of industrial production related technology, specifically relating to an industrial robot loading and unloading device. Background Technology

[0002] In modern industrial production, material loading and unloading operations are a crucial part of the production process. Traditional material loading and unloading methods mainly rely on manual operation, which has many drawbacks.

[0003] On the one hand, manual loading and unloading is inefficient, labor-intensive, and prone to fatigue and operational errors, affecting the continuity and stability of production. Especially in large-scale production, manual loading and unloading cannot meet the demands of high-efficiency production, becoming a bottleneck restricting the improvement of enterprise production efficiency.

[0004] On the other hand, manual operation has limited precision, making it difficult to accurately position and grasp materials. In some production scenarios with high precision requirements, manual loading and unloading may lead to inaccurate material placement, affecting the quality of subsequent processing steps.

[0005] Furthermore, with the continuous development of industrial production, the production environment has become increasingly complex and dangerous. Manual loading and unloading operations may expose workers to hazardous working environments, such as high temperatures, high pressures, and toxic or harmful gases, posing a threat to their lives.

[0006] To address the shortcomings of traditional manual material handling methods, industrial robot loading and unloading devices have emerged. However, existing industrial robot loading and unloading devices still have some problems in practical applications. For example, some devices lack flexibility and struggle to adapt to the gripping needs of materials with different shapes and sizes; some devices have a single gripping method, failing to meet the gripping needs of different types of materials and thus failing to meet diverse production requirements.

[0007] In conclusion, in order to improve the efficiency, precision and safety of industrial production, there is an urgent need for a new type of industrial robot loading and unloading device that can innovate and improve in terms of flexibility, stability and functionality to better meet the needs of modern industrial production.

[0017] Compared with the prior art, this utility model provides an industrial robot loading and unloading device, which has the following beneficial effects:

[0018] 1. Multi-directional adjustment structure innovation: It includes a combination of a limiting chassis, a rotating chassis, a connecting turntable, and multiple robotic arms, which can realize multi-directional rotation adjustment, thereby accurately determining the direction of loading and unloading and the material gripping position, improving the flexibility and accuracy of loading and unloading.

[0019] 2.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-5 The industrial robot loading and unloading device shown includes a limiting chassis 1, a rotating chassis 2 rotatably connected to the upper end of the limiting chassis 1, a connecting rotating seat 3 fixedly connected to the center of the upper end of the rotating chassis 2, a first robotic arm 4 rotatably connected to the upper end of the connecting rotating seat 3, a second robotic arm 5 rotatably connected to the upper end of the first robotic arm 4, a third robotic arm 6 rotatably connected to the front end of the second robotic arm 5, and a gripping seat 7 fixedly connected to the lower end of the third robotic arm 6. Gripping claws 8 are slidably connected to the left and right sides of the lower end of the gripping seat 7. In industrial production, the robot loading and unloading device can automate the loading and unloading of materials, thereby reducing labor costs and improving production efficiency. The robot loading and unloading device adjusts the loading and unloading direction by rotating the rotating chassis 2 and the connecting rotating seat 3, and adjusts the position of the gripping seat 7 and the two gripping claws 8 by rotating the first robotic arm 4, the second robotic arm 5 and the third robotic arm 6, thereby accurately gripping the materials.

[0030] Preferably, each of the two gripping claws 8 has a limiting block 9 fixedly connected to its upper end, and is engaged with the gripping base 7 at its lower end by the limiting block 9. An adjusting arm 10 is rotatably connected to the center of the upper end of each of the two limiting blocks 9, and an adjusting nut 11 is rotatably connected between the two adjusting arms 10. Both the adjusting arms 10 and the adjusting nut 11 are located inside the gripping base 7 and between the two gripping claws 8. An adjusting screw 12 passes vertically through the center of the upper end of the adjusting nut 11, and the adjusting screw 12 is threadedly connected to the adjusting nut 11 and passes through the center of the upper end of the gripping base 7. Inside the core, the upper end of the adjusting screw 12 is equipped with an adjusting motor 13, and the upper end of the adjusting screw 12 is rotatably connected to the lower center of the adjusting motor 13. The adjusting motor 13 is fixedly connected to the motor chamber opened at the lower end of the third robotic arm 6. After the positions of the two gripping claws 8 are adjusted, the adjusting screw 12 rotates through the adjusting motor 13, and drives the adjusting nut 11 to move upward through the thread. The adjusting nut 11 pulls the two gripping claws 8 and the two limiting blocks 9 toward the center through the two adjusting arms 10, thereby clamping and gripping the material.

[0031] Preferably, an adsorption pad 14 is engaged inside the lower end of the gripper 8. Adsorption channels 15 extend vertically through the gripper 8 and the adsorption pad 14. The upper opening of the adsorption channel 15 is located inside the upper side of the gripper 8 away from the adjusting arm 10, and the lower opening of the adsorption channel 15 is funnel-shaped. A connecting plug 16 is provided at the upper opening of the adsorption channel 15. The connecting plug 16 is fixedly connected to the upper outside of the gripper 8 away from the adjusting arm 10, and multiple air guide grooves are formed inside the connecting plug 16 at the end away from the gripper 8. Both ends of the gripper 7 have connecting channels 17, and the lower openings of the two connecting channels 17 are located inside the inner walls of the lower openings of the gripper 7. Two connecting plugs 16 are inserted into the lower openings of the two connecting channels 17. The upper ends of the two connecting channels 17 are connected to a negative pressure chamber 18. The upper front end of the negative pressure chamber 18 is connected to a suction pipe 19, which is located inside the front end of the third robotic arm 6. The rear end of the suction pipe 19 is equipped with a suction motor 20, and the front end of the suction motor 20 is rotatably connected to a suction pump. The suction turbine fan 21 is rotatably connected inside the suction pipe 19. When the material to be gripped by the two gripping claws 8 is relatively fragile, the two gripping claws 8 can adsorb and grip the material through the adsorption pad 14 set at the lower end. In this process, the two gripping claws 8 are first slid to the outermost side, and the two connecting plugs 16 are inserted into the lower opening of the two connecting channels 17, so that the adsorption channel 15 inside the gripping claws 8 is connected to the connecting channel 17. At the same time, the suction motor 20 drives the suction turbine fan 21 to rotate, and through the suction turbine fan... The rotation of 21 draws air out of the negative pressure chamber 18, creating negative pressure inside the two connecting channels 17 and the two adsorption channels 15 that are connected to the negative pressure chamber 18. Since the lower opening of the adsorption channel 15 is located inside the center of the lower end of the adsorption pad 14 and is funnel-shaped, and the adsorption pad 14 is made of soft rubber with a smooth outer wall at the lower end, the material located at the lower end of the adsorption pad 14 can be adsorbed by the negative pressure of the adsorption channel 15, thereby lifting the material and achieving adsorption and gripping of the material.

[0032] Preferably, a sealing sliding hole 22 is provided inside the inner wall of the lower opening of the connecting channel 17, and a sealing head 23 is engaged inside the lower opening of the connecting channel 17. The sealing head 23 is located at the end of the connecting plug 16 away from the gripper 8. A limiting air guide ring 24 is fixedly connected to the outer side of the end of the sealing head 23 away from the connecting plug 16, and multiple air holes are provided inside the limiting air guide ring 24. A sealing spring 25 is provided at the end of the limiting air guide ring 24 away from the connecting plug 16. The sealing head 23 and the limiting air guide ring 24 are elastically connected inside the sealing sliding hole 22 through the sealing spring 25. When the material is clamped and gripped, since the sealing head 23 is engaged inside the lower opening of the connecting channel 17 and can seal the lower opening of the connecting channel 17 through the sealing head 23, no foreign matter will be sucked into the connecting channel 17, and the clamped material will not be affected, thus ensuring stable clamping.

[0033] Preferably, when adsorbing and grasping materials, since the connector 16 needs to be inserted into the lower opening of the connecting channel 17, the sealing head 23 can be completely slid into the sealing hole 22 under the pushing of the connector 16. This allows the adsorption channel 15 to communicate with the inside of the connecting channel 17 through the connector 16 and the multiple air guide grooves and multiple air vents inside the limiting air guide ring 24. This allows the adsorption channel 15 to communicate with the negative pressure chamber 18 and generate negative pressure through the rotation of the suction fan 21 to adsorb materials.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
