Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a hybrid robot processing line. Background Art

[0002] The hybrid robot combines the characteristics of serial robots and parallel robots. It has the advantages of high precision, large working space, strong load-bearing capacity, and fast response speed. It provides an effective solution for the high-precision processing and manufacturing of large and complex structural parts. The hybrid robot processing line is an advanced manufacturing technology that combines automated robotics technology and artificial intelligence technology.

[0003] In current industrial production, due to the wide variety of products, changing demands and rising labor costs, the traditional assembly line production model has been unable to meet market demand. Hybrid robots use advanced equipment such as robots, sensors, and visual recognition systems to achieve automatic monitoring, adjustment, and optimization of the production process. In the hybrid robot processing line, there are not only traditional fixed robots, but also flexible mobile robots, collaborative robots, and autonomous navigation robots. These robots can be flexibly scheduled and work together according to the needs of production tasks to improve production efficiency and flexibility. At the same time, the hybrid robot processing line equipped with artificial intelligence technology can also continuously improve its own intelligence level through learning and optimization algorithms to adapt to different production scenarios and changes in demand. The hybrid robot processing line not only improves the factory's production efficiency and quality, but also reduces labor costs and labor intensity, and promotes the transformation, upgrading, and intelligent development of the manufacturing industry.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the hybrid robot processing line, the lifting platform drives the mounting seat and the welding head to descend. During the descent, the air pipe rotates and adjusts the angle so that the air pipe drives the nozzle to point to the welding position of the workpiece body, and the welding head contacts the contact surface of the two workpiece bodies. At the same time, the telescopic member drives the mounting seat to move, so that the mounting seat drives the welding head to move along the contact surface of the workpiece body, thereby welding the two workpiece bodies. The air pipe continuously sprays protective gas during welding, so that when the welding head welds the workpiece body, the air pipe can accurately spray protective gas to the welding position through the nozzle;

[0018] At the same time, the lifting platform also drives the pressure rod to descend, squeezing the upper end of the movable rod outward, causing the movable rod to rotate and squeeze and reel in the scroll spring, so that the lower end of the pressure rod drives the first positioning plate and the second positioning plate to move through the connecting rod, so that the workpiece body is squeezed and clamped by the second positioning plate to avoid displacement of the workpiece body during the welding process. After the welding is completed, the lifting platform rises and resets, and the movable rod drives the first positioning plate and the second positioning plate to reset under the action of the rebound force of the scroll spring. Not only that, when the second positioning plate contacts the workpiece body, the still moving first positioning plate drives the sleeve to be sleeved on the outside of the sliding tube, and The first spring is squeezed so that the second positioning plate squeezes and positions the workpiece body. When the size of the workpiece body is large, the first spring is squeezed to a large extent, and when the size of the workpiece body is small, the first spring is squeezed to a small extent, thereby improving the adaptability of the positioning component to workpiece bodies of different sizes, and solving as much as possible the problem that when the prior art uses a hybrid robot to weld the workpiece in an assembly line operation, it is usually necessary to spray a shielding gas on the welding point while welding the workpiece. However, when the workpiece has a special shape, the nozzle for spraying the shielding gas is easily blocked by the workpiece, making it difficult to accurately spray the shielding gas on the welding point, thereby easily affecting the welding processing effect.

[0019] 2. In the hybrid robot processing line, the mounting seat drives the welding head, air pipe and rack to descend, and the air pipe is blocked by the workpiece body, so that the support rod and the arc tube slide on the side of the mounting seat, and at the same time, the second spring and the third spring are squeezed, and the gear drives the air pipe to rotate through the meshing of the rack and the gear. At the same time, the arc rod slides into the arc tube and compresses the fourth spring, so that the lower end of the air pipe drives the nozzle to deflect, so as to facilitate the adjustment of the jet angle of the air pipe according to the shape of the workpiece body, so that the air outlet end of the air pipe always points to the welding part of the workpiece body, so as to facilitate the improvement of the accuracy of spraying the protective gas on the welding part of the workpiece body. Subsequently, after the welding is completed, the lifting platform drives the welding head and the air pipe to rise, and at the same time, the support rod is reset under the action of the rebound force of the second spring, and the arc rod is reset under the action of the rebound force of the third spring and the fourth spring, so that the angle of the air pipe is restored.

[0020] 3. In the hybrid robot processing line, after the air pipe collides with the workpiece body, the mounting seat drives the fixing frame to descend, and the limiting ball slides in the limiting groove. The sliding of the limiting ball in the limiting groove realizes the change of the distance between the adjusting plug and the nozzle, so that the control rod descends relative to the air pipe and compresses the fifth spring, so that the control rod drives the adjusting plug to move down to the bottom of the air pipe, reducing the gap between the adjusting plug and the air outlet end of the air pipe, thereby increasing the flow rate of the protective gas under the condition of a certain amount of protective gas filling, and increasing the distance of the protective gas injection, so that after the angle of the air pipe is adjusted, even if the distance from the welding head is increased, it can still ensure sufficient protective gas injection to the welding point.

Subsequently, after the welding is completed, the lifting platform 100 drives the welding head 140 and the air pipe 150 to rise, and at the same time, the support rod 180 is reset under the action of the rebound force of the second spring 181, and the arc rod 192 is reset under the action of the rebound force of the third spring 191 and the fourth spring 193, thereby restoring the angle of the air pipe 150.

This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8A control rod 200 is slidably inserted into the upper end of the air pipe 150, and the insertion point remains sealed. An adjusting plug 201 is fixedly installed at the lower end of the control rod 200. The adjusting plug 201 is arranged in the inner cavity of the air pipe 150, and the adjusting plug 201 is arranged in a truncated cone shape. The inner wall of the bottom of the air pipe 150 is the same shape as the adjusting plug 201. A gap is left between the adjusting plug 201 and the inner wall of the end of the air pipe 150, and in the initial state, the adjusting plug 201 is away from the bottom of the air pipe 150. A retaining ring 202 is fixedly sleeved in the middle part of the control rod 200, and a through hole 203 is opened on the side of the retaining ring 202 to facilitate the passage of protective gas through the through hole 203. The retaining ring 202 is slidably matched with the inner wall of the air pipe 150, so that the control rod 200 remains stable when moving in the air pipe 150. A fifth spring 204 is also sleeved on the outside of the control rod 200, and the two ends of the fifth spring 204 are respectively fixedly connected to the upper side of the retaining ring 202 and the air pipe 150.

The limiting ball 210 is slidably inserted in the limiting groove 212, and the limiting groove 212 is set as an arc groove.

[0044] In this embodiment: after the air pipe 150 collides with the workpiece body 120, the mounting seat 130 drives the fixing frame 211 to descend, and the limiting ball 210 slides in the limiting groove 212. The sliding of the limiting ball 210 in the limiting groove 212 realizes the change of the distance between the adjusting plug 201 and the nozzle 151, so that the control rod 200 descends relative to the air pipe 150 and compresses the fifth spring 204, so that the control rod 200 drives the adjusting plug 201 to move down to the bottom of the air pipe 150, reducing the gap between the adjusting plug 201 and the air outlet end of the air pipe 150, thereby increasing the flow rate of the protective gas under the condition of a certain amount of protective gas filling, so that the distance of the protective gas injection is increased, so that after the angle of the air pipe 150 is adjusted, even if the distance from the welding head 140 is increased, it can still ensure sufficient protective gas injection to the welding point.
