[0030] 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.

[0031] Please see Figures 1-8An automatic riveting device for an electromagnetic valve includes a riveting device body 1 for automatic riveting, and a fixed frame 2. The fixed frame 2 contains a conveyor belt 3 for transporting the workpiece to be riveted. Fixed seats 4 are fixedly installed on opposite sides of the fixed frame 2. A U-shaped support frame 5, positioned above the conveyor belt 3, is located between the two fixed seats 4. The top wall of the support frame 5 has a first telescopic device 6 with a telescopic effect. A movable seat 7, aligned with the fixed seats 4, is fixedly installed at the lower end of the first telescopic device 6. A fixed plate 8 is located below the movable seat 7, and a visual positioning device 9 for visual monitoring is located below the fixed plate 8. The riveting head of the riveting device body 1 is fixedly installed below the fixed plate 8. A first drive motor 10 for driving the support frame 5 is fixedly installed at the end of the fixed seat 4. A second drive motor 11 for driving the first telescopic device 6 is fixedly installed on one side of the support frame 5. A third drive motor 12 for driving the riveting head of the riveting device body 1 is fixedly installed at the end of the movable seat 7. Both ends of the support frame 5 are fixed. A first sliding block 21 is installed. A first sliding groove 22 adapted to the first sliding block 21 is opened on the upper part of the fixed base 4. A first drive screw 23, one end of which is fixedly installed to the output end of the first drive motor 10, is rotatably connected in the first sliding groove 22. The first drive screw 23 passes through the first sliding block 21 and is threadedly connected to it. A second sliding block 24 is fixedly installed on the upper part of the first telescopic device 6. A second sliding groove 25 adapted to the second sliding block 24 is opened on the inner top wall of the support frame 5. A second drive screw 26, one end of which is fixedly installed to the output end of the second drive motor 11, is rotatably connected in the second sliding groove 25. The second drive screw 26 passes through the second sliding block 24 and is threadedly connected to it. A third sliding block 27 is fixedly installed on the upper part of the fixed plate 8. A third sliding groove 28 adapted to the third sliding block 27 is opened on the lower part of the movable base 7. A third drive screw 29, one end of which is fixedly installed to the output end of the third drive motor 12, is rotatably connected in the third sliding groove 28. The third drive screw 29 passes through the third sliding block 27 and is threadedly connected to it.

[0032] Specifically, when riveting solenoid valve components, the solenoid valve body is placed intermittently on the conveyor belt 3. The fixing frame 2 is equipped with a drive component for conveying the conveyor belt 3. The drive component is opened intermittently, and the conveyor belt 3 drives the solenoid valve body to move. In actual operation, the time for placing the component on the solenoid valve body is determined according to the shape and installation position of the part to be riveted. If the component will not fall off due to the conveyor belt 3, it can be directly snapped or bonded to the solenoid valve body at the starting position of the conveyor belt 3. If the component will fall off due to the conveyor belt 3, it can be placed on the solenoid valve body during the conveying process. When the component reaches the support frame 5, it is placed on the upper part of the solenoid valve body by a robotic arm or manually. When the solenoid valve to be riveted is transported to the position below the support frame 5, the vision positioning device 9, in conjunction with the external main controller, identifies the position of the solenoid valve. Based on the identified position of the solenoid valve and the position to be riveted on the solenoid valve, the position of the riveting head of the riveting device body 1 is adjusted. The main controller turns on the second drive motor 11, and the output end of the second drive motor 11 drives the second drive screw 26 to rotate. When the second drive screw 26 rotates, it drives the second sliding block 24 to slide in the second sliding groove 25. The second sliding block 24 moves the position of the first telescopic device 6. The width of the conveyor belt 3 is adjusted, and the third drive motor 12 is activated. The output of the third drive motor 12 drives the third drive screw 29 to rotate. When the third drive screw 29 rotates, it drives the third sliding block 27 to slide in the third sliding groove 28. The third sliding groove 28 drives the fixed plate 8 to move along the conveying direction of the conveyor belt 3, thereby adjusting the position of the rivet head of the riveting device body 1. Then, the first telescopic device 6 is activated. The telescopic end of the first telescopic device 6 drives the rivet head of the riveting device body 1 to move downward. The rivet head of the riveting device body 1 rotates to rivet the solenoid valve. By adjusting the position of the rivet head of the riveting device body 1, multiple rivet points are riveted. After riveting is completed, the conveyor belt 3 restarts to complete the automatic riveting of the solenoid valves. This eliminates the need for manual riveting of each solenoid valve individually, improving the efficiency of riveting. When there is a slight deviation between the position of the solenoid valve on the conveyor belt 3 and the position of the support frame 5, two synchronous first drive motors 10 can be started. The output of the first drive motor 10 drives the first drive screw 23 to rotate. When the first drive screw 23 rotates, it drives the first sliding block 21 to move within the first sliding groove 22. The movement of the two first sliding blocks 21 moves the support frame 5, adjusting the position of the support frame 5 and improving the accuracy of riveting the solenoid valves.

[0033] As a technical optimization of this utility model, the support frame 5 is fixedly installed with a second telescopic device 13 with telescopic effect on opposite sides. The telescopic ends of the second telescopic devices 13 penetrate the support frame 5 and are fixedly installed with clamping plates 14 adapted to the side of the part to be riveted. When the solenoid valve is transported to the position below the support frame 5, the position of the support frame 5 is adjusted, and the two second telescopic devices 13 are activated at the same time. The telescopic ends of the second telescopic devices 13 drive the clamping plates 14 to move. The two clamping plates 14 adapted to the side of the solenoid valve clamp and fix the solenoid valve, improving the stability when riveting the solenoid valve. A support plate 20 is fixedly installed inside the fixed frame 2. The upper part of the support plate 20 is in close contact with the upper part of the conveyor belt 3. The support plate 20 plays a supporting role and prevents the conveyor belt 3 from collapsing.

[0034] As a technical optimization of this utility model, two symmetrical positioning shafts 16 are fixedly installed on the upper part of the fixed frame 2 near the starting end of the conveyor belt 3. The side of the positioning shaft 16 is provided with a guide plate 15 for guiding the parts to be riveted. The guide plate 15 is rotatably connected to the side of the positioning shaft 16. Two symmetrical fixing blocks 17 are fixedly installed on the upper part of the fixed frame 2. An arc-shaped positioning plate 18 concentric with the positioning shaft 16 and penetrating the fixing block 17 is fixedly installed on the side of the guide plate 15. A positioning bolt 19 is threaded through the upper part of the fixing block 17 and has one end tightly abutting against the side of the arc-shaped positioning plate 18. This guides and limits the solenoid valves during the conveying process, placing the solenoid valves in a uniform direction at approximately the middle position of the conveyor belt 3. When the solenoid valve is delivered to the positions of the two guide plates 15, the two V-shaped guide plates 15 guide it to the middle position of the conveyor belt 3, which facilitates the clamping and riveting of the solenoid valve later. At the same time, the angle between the two guide plates 15 can be adjusted according to the size of the solenoid valve. During adjustment, the positioning bolt 19 is loosened and the guide plate 15 is rotated along the positioning shaft 16. The arc-shaped positioning plate 18 is concentric with the positioning shaft 16 and moves accordingly. After the position of the guide plate 15 is adjusted, the positioning bolt 19 is tightened. One end of the positioning bolt 19 abuts against the arc-shaped positioning plate 18, which limits and fixes the position of the guide plate 15, improving the accuracy of riveting the solenoid valve.
