[0002] Vacuum chambers are widely used in modern manufacturing, especially in the fields of electronics, semiconductors, and optical components. These industries have extremely high requirements for the sealing, cleanliness, and precision of their products, and welding in a vacuum environment can effectively avoid the effects of oxidation and other contaminants, thus ensuring welding quality. With the development of industrial technology, using robotic arms for precision operations has become one of the important means to improve product quality and production efficiency.

[0003] Most common vacuum chamber welding equipment currently uses a fixed worktable design. This leads to the need for frequent adjustments to equipment parameters or even replacement of the entire work platform when processing workpieces of different sizes or shapes. This not only increases the difficulty of operation and time costs, but also limits the versatility and flexibility of the equipment. In addition, since the adjustment of the welding head position usually relies on a manual or semi-automatic control system, it is not precise enough for fine angle and distance adjustments, which affects the consistency and reliability of the final welding effect. This structural deficiency is particularly prominent when facing increasingly complex manufacturing needs, and it is urgent to solve the above problems by improving the mechanical structure in order to adapt to diversified and personalized production requirements.

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: a vacuum cavity welding and assembly machine based on a robotic arm, including a support platform 1. A switching plate 2 is rotatably connected to the inside of the support platform 1 via bearings. The switching plate 2 has a rectangular guide groove and a guide seat 3 for mounting the robotic arm base. Support brackets 4 are fixed to both sides of the support platform 1. The horizontal portion of the support brackets 4 has mounting holes. A motor 5 for driving the switching plate 2 to rotate is fixedly installed at the bottom center of the support platform 1 via bolts. A mating toothed ring 8 is provided on the bottom wall of the switching plate 2. A locking toothed ring 9 that mates with the mating toothed ring 8 is welded and fixed to the bottom inside the support platform 1. The locking toothed ring 9 is adjusted in height by a pushing mechanism consisting of a lifting rod 6 and a push shaft 7. This structure allows for adjustment when the support platform needs to be used for welding and assembly. When the position or angle of the robot arm base is adjusted to accommodate workpieces of different sizes or shapes, the motor 5 drives the switching plate 2 to rotate inside the support platform 1. This automated method allows for rapid and precise positioning of the robot arm. Simultaneously, the guide seat 3 can move along the rectangular guide groove on the switching plate 2, ensuring the flexibility and stability of the robot arm base's installation position. When the switching plate 2 rotates to the predetermined position, the lifting rod 6 rises under the action of the push shaft 7, causing the locking toothed ring 9 to engage with the mating toothed ring 8 on the bottom wall of the switching plate 2, thus firmly fixing the switching plate 2 and preventing unnecessary displacement during welding. The support bracket 4 enhances the structural strength of the entire support platform 1, ensuring sufficient support during the rotation and fixing of the switching plate 2. This device provides support while maintaining the overall stability of the equipment. It solves the problems of high operational difficulty, high time cost, and limited equipment versatility and flexibility caused by the fixed worktable design in existing technologies. Furthermore, it overcomes the inaccuracy in fine angle and distance adjustments caused by traditional manual or semi-automatic control systems for adjusting the welding head position, improving the consistency and reliability of the final welding effect. This not only enhances the equipment's adaptability to different workpieces but also achieves higher welding precision, significantly improving the consistency and reliability of welding quality, meeting increasingly complex manufacturing needs, and is suitable for diverse and personalized production requirements. The lifting rod 6 is horizontally positioned on the outside of the bottom end of the support platform 1, and a hydraulic push rod is fixed in the middle of the bottom of the support platform 1. The output end of the hydraulic push rod is fixedly connected to the middle of the lifting rod 6. The push shaft 7 is fixed on both sides of the top of the lifting rod 6, and the top end of the push shaft 7 penetrates into the interior of the support platform 1 and is fixedly connected to the bottom wall of the locking tooth ring 9. When it is necessary to fix the position of the switching plate 2, the hydraulic push rod fixed in the middle of the bottom of the support platform 1 is activated, and its output end pushes the middle part of the lifting rod 6, causing the lifting rod 6 to move upward as a whole. At the same time, the push shafts 7 on both sides of the top of the lifting rod 6 rise accordingly, ensuring that the locking tooth ring 9 can accurately mesh with the mating tooth ring 8 on the bottom wall of the switching plate 2. This linkage not only ensures that the switching plate 2 can be firmly locked after rotating to the predetermined position, preventing any unnecessary displacement, but also precisely controls the movement of the lifting rod 6 through the hydraulic push rod.This design further enhances positioning accuracy and system reliability. The bottom of the guide seat 3 is connected to the bottom wall of the rectangular guide groove on the switching plate 2 via linear guide rails 11, which are symmetrically arranged in two sets. This structure allows the guide seat 3 to move along the linear guide rails 11 when the position of the robot base needs adjustment, providing extremely high guiding accuracy and stability, preventing offset or shaking, and thus further ensuring the accuracy and reliability of the robot base installation position. The top of the switching plate 2 also has counterweight slots on both sides, and dynamic counterweight blocks 12 are driven by cylinders within these slots. This structure allows the cylinders to precisely adjust the position of the dynamic counterweight blocks 12 according to control system commands when the robot needs to be adjusted to different positions or angles to accommodate workpieces of different sizes and shapes, ensuring the switching plate 2 maintains dynamic balance. The movement of the dynamic counterweight blocks 12 compensates for imbalances caused by changes in the weight of the robot base and the tools mounted on it, ensuring the stability of the switching plate 2. To ensure smooth rotation and stability at rest, the positions of the mating toothed ring 8 and the locking toothed ring 9 correspond, and both rings have a number of uniformly arranged locking teeth. These teeth on the locking ring 9 precisely mesh with the mating toothed ring 8 on the bottom wall of the switching plate 2, forming a stable mechanical locking system. This linkage mechanism not only provides a highly reliable fixing effect, preventing any minor displacement of the switching plate 2 during welding, but also ensures consistency and repeatability in each positioning. A reinforcing rib 10 is provided on the inner side of the connection between the support platform 1 and the support bracket 4, and the reinforcing rib 10 is welded and fixed to the contact surfaces of both the support platform 1 and the support bracket 4. This reinforcing rib 10 effectively disperses and bears the stress acting on the support platform 1 and the support bracket 4, preventing deformation or displacement caused by external forces. This not only improves the strength of the connection but also ensures long-term stable operation of the equipment under high-load working conditions.

[0019] Working Principle: When using this robotic arm-based vacuum chamber welding assembly machine, the entire device is first fixed in a suitable working position through the mounting holes on the support bracket 4. Then, the robotic arm base is bolted to the top surface of the guide seat 3, and the position of the robotic arm base is adjusted according to the specific requirements of the workpiece. At this time, the guide seat 3 moves along the rectangular guide groove on the switching plate 2 and is guided by the linear guide rail 11 to ensure accurate positioning of the robotic arm base. Next, when it is necessary to adjust the angle or position of the robotic arm to adapt to workpieces of different sizes or shapes, the control system commands the motor 5 to start, driving the switching plate 2 to rotate inside the support platform 1, thereby quickly and accurately positioning the robotic arm. At the same time, the cylinder adjusts the position of the dynamic counterweight block 12 in the counterweight groove at the top of the switching plate 2 according to the control system command to maintain the dynamic balance of the switching plate 2 and compensate for the impact of the robotic arm base and the... The imbalance caused by the change in tool weight is addressed by activating the hydraulic push rod fixed in the middle of the bottom of the support platform 1 once the switching plate 2 rotates to the predetermined position. Its output end pushes the middle part of the lifting rod 6, causing the lifting rod 6 to move upward as a whole. As the lifting rod 6 rises, the push shafts 7 fixed on both sides of its top rise accordingly. The top of the push shaft 7 penetrates the interior of the support platform 1 and is fixedly connected to the bottom wall of the locking toothed ring 9, so that the locking toothed ring 9 precisely meshes with the mating toothed ring 8 on the bottom wall of the switching plate 2, firmly locking the position of the switching plate 2 and preventing any unnecessary displacement. Throughout the process, the reinforcing ribs 10 effectively disperse and bear the stress acting on the support platform 1 and the support bracket 4, ensuring the stability and strength of the equipment during operation. Finally, through this series of coherent operation procedures, the flexible adjustment and stable fixation of the robot base are achieved, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
