[0002] With the rapid development of the manufacturing industry, the application of automated equipment is becoming increasingly widespread, especially in fields such as precision assembly and electronic component assembly. Automated assembly robots are favored for their ability to perform high-precision and high-speed work. These robots not only significantly improve production efficiency but also ensure product quality stability to a certain extent. Driven by the pursuit of higher production efficiency and lower manufacturing costs, multi-station collaborative assembly robots are gradually becoming a focus of research and application.

[0003] While existing single-station assembly robots can complete basic assembly tasks, they often prove inefficient when faced with complex assembly processes or multi-step continuous operations. Furthermore, while existing dual-station assembly robots increase efficiency by adding more worktables, their structural design has significant shortcomings, particularly in the coordination and switching speed between the robot and the worktables. For example, after completing an assembly task on one worktable, the robot requires a considerable amount of time to accurately switch to another worktable to continue working, leading to a decrease in overall production efficiency. Additionally, due to the lack of effective positioning and locking mechanisms, worktables are prone to shifting during switching, affecting assembly accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency dual-station assembly robot to solve the problems of slow speed, inaccurate positioning, and poor stability of current dual-station assembly robots during worktable switching, as mentioned in the background art.

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a high-efficiency dual-station assembly robot, including a robot body 1, a robot base 2, and a fixed base 3. A rotating disk 4 is driven by a motor inside the fixed base 3. The motor is fixed to the center of the bottom of the fixed base 3 by bolts. A pushing groove is provided on one side of the top of the rotating disk 4, and a driving block 5 is provided in the pushing groove at the top of the rotating disk 4. The robot body 1 is fixedly mounted on the driving block 5 by the robot base 2 and bolts. Several dynamically balancing blocks 7 with adjustable positions are evenly distributed on the top of the rotating disk 4. A quick braking mechanism 6 is provided on both sides of the bottom of the fixed base 3. The quick braking mechanism 6 consists of a brake cylinder 61, a brake push rod 62, and a brake pad 63. The brake cylinder 61 is vertically fixed to the fixed base 3. On the bottom wall of the fixed base 3, a brake push rod 62 is movably inserted through the bottom wall of the fixed base 3. A brake pad 63 is welded and fixed to the top of the brake push rod 62. The output end of the brake cylinder 61 is fixedly connected to the bottom end of the brake push rod 62 through a connecting block. The bottom of the rotating disk 4 is evenly provided with several brake slots that match the structure of the brake pad 63. In this structure, the motor at the bottom of the fixed base 3 drives the rotating disk 4 inside the fixed base 3 to rotate. The drive block 5 can also move synchronously in the groove at the top of the rotating disk 4, so that the drive block 5 and the robot base 2 cooperate to drive the robot body 1 to adjust its position. In this process, the dynamic balance block 7 can automatically adjust its position according to the weight and distribution of the robot body 1 to ensure the stability of the rotating disk 4 when it is running at high speed. This design reduces vibration and shaking, improving assembly stability and precision. Simultaneously, when rapid worktable switching is required, the quick-braking mechanism 6 on both sides of the bottom of the fixed base 3 activates. The brake cylinder 61 pushes the brake push rod 62, causing the brake pad 63 to contact and lock the brake slot at the bottom of the rotating disk 4, quickly fixing the rotating disk 4 in the target position. This ensures the accuracy and speed of workstation switching. This structure not only achieves efficient and smooth transitions between two workstations but also solves the problems of low efficiency in single-station assembly robots and slow switching and inaccurate positioning in dual-station assembly robots through an optimized dynamic balance system and quick-braking mechanism 6. This significantly improves overall production efficiency and assembly quality. The fixed base 3 has grooves on both sides of its bottom wall. The brake pad 63 is movably mounted in a groove on the bottom wall of the fixed base 3, and guide blocks 64 are provided on both sides of the brake pad 63. Guide openings 65 that mate with the guide blocks 64 are provided on the inner walls of both sides of the groove on the bottom wall of the fixed base 3. When the rapid braking mechanism 6 is activated, the brake cylinder 61 pushes the brake push rod 62 to raise and lower the brake pad 63. As the brake pad 63 rises and falls, it causes the guide blocks 64 and guide openings 65 to slide until the brake pad 63 quickly engages with the brake latch at the bottom of the rotating disk 4, achieving rapid locking of the rotating disk 4. This ensures the smoothness and reliability of the braking process and avoids locking failure or accelerated wear caused by unstable movement of the brake pad 63. The top of the rotating disk 4 is provided with several adjustment grooves 71 that match the structure of the dynamic balance block 7.Furthermore, the inner walls of both sides of the adjustment groove 71 are connected to the two sides of the dynamic balance block 7 via linear guide rails. With this structure, when the rotating disk 4 rotates, the dynamic balance block 7 can slide freely along the linear guide rails in the adjustment groove 71 according to the load changes of the robot body 1, and adjust its position in real time to achieve the best balance state, ensuring the stability of the rotating disk 4 when it is running at high speed. The inner end of the top push groove of the rotating disk 4 is provided with a push cylinder 8, and the output end of the push cylinder 8 is fixedly connected to the inner side of the drive block 5. The two sides of the bottom of the drive block 5 are provided with sliding blocks 51, and the bottom wall of the top push groove of the rotating disk 4 is symmetrically provided with sliding blocks 51. The sliding groove structure allows the drive block 5 to move along the sliding groove when the cylinder 8 is working. The sliding block 51 slides smoothly within the groove on the top of the rotating disk 4, ensuring stable movement of the drive block 5. This allows the robot body 1 to accurately move from one workstation to another, improving the speed and accuracy of workstation switching. Vertically distributed connectors 31 are provided on both sides of the bottom of the fixed base 3, and mounting holes are opened at the bottom of the connectors 31. This structure of connectors 31 not only provides stable support but also facilitates the installation and disassembly of the equipment, improving its flexibility and adaptability.

[0018] Working Principle: When using this high-efficiency dual-station assembly robot, firstly, the fixed base 3 is fixed to the work platform through the mounting holes on the two connectors 31. Next, the motor at the bottom of the fixed base 3 starts and drives the rotating disk 4 to rotate. At the same time, it drives the cylinder 8 to start, and its output end pushes the drive block 5 to move along the sliding groove on the bottom wall of the groove at the top of the rotating disk 4. The sliding block 51 at the bottom of the drive block 5 slides smoothly in the sliding groove. As the drive block 5 moves, the robot body 1 can accurately move from one station to another. During the rotation of the rotating disk 4... In the middle, several dynamic balance blocks 7 evenly distributed on the top slide freely along the linear guide rail in the adjustment groove 71 according to the weight and distribution of the robot body 1, and adjust their positions in real time to achieve the best balance. When the rotating disk 4 rotates to the appropriate position, the quick braking mechanism 6 on both sides of the bottom of the fixed seat 3 is activated, that is, the brake cylinder 61 pushes the brake push rod 62 to make the brake pad 63 rise and fall. When the brake pad 63 rises and falls, it drives the guide block 64 and the guide port 65 to slide until the brake pad 63 fits against the brake slot at the bottom of the rotating disk 4, realizing the quick locking of the rotating disk 4, thereby completing a series of tasks.

[0019] Although the present invention 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 invention should be included within the protection scope of the present invention.
