Description

Technical Field

[0001] This utility model relates to the technical field of circuit breaker component assembly equipment, and in particular to an automatic pin-threading and riveting device for circuit breakers. Background Technology

[0002] Circuit breakers are commonly used switching devices in daily life. Their main function is to close, carry, and interrupt current under normal circuit conditions and to close, carry, and interrupt current under abnormal circuit conditions within a specified time. After the internal parts of the circuit breaker are installed, the circuit breaker housing needs to be riveted together to ensure a complete connection. In current technology, the riveting of circuit breakers is usually done manually by workers. However, this processing method is relatively inefficient and cannot meet the needs of mass production. In addition, common riveting machines on the market have the following problems: First, they are prone to inaccurate rivet feeding positions, which can lead to the circuit breakers not being installed correctly. Second, the processing usually involves manual loading and unloading, resulting in high labor costs. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an automatic pin-threading and riveting device for circuit breakers that is highly automated and can improve yield and processing efficiency.

[0004] The technical solution of this utility model is as follows: An automatic rivet-fitting device for circuit breakers includes a base, a rivet feeding device connected to the base, a circuit breaker feeding device connected to the base, a pressing device connected to the base, and a controller. The rivet feeding device includes a first rotating feed plate connected to the base, several connecting pipes connected to the first rotating feed plate, a fixed base connected to the base, several rivet-fitting pipes connected to the fixed base, and an electric switching switch connected to the rivet-fitting pipes. The number of connecting pipes, rivet-fitting pipes, and electric switching switches is the same. When the electric switching switch is in the open state, it can block the rivet-fitting pipes. When the electric switching switch is in the closed state, the rivet can pass through the rivet-fitting pipes. The circuit breaker feeding device includes a conveyor belt connected to the base, a drive motor for driving the conveyor belt, a first push plate slidably connected to the base, a first hydraulic cylinder for driving the first push plate, a second push plate slidably connected to the base, and a device for driving the second push plate. The second hydraulic cylinder, the first push plate can push the circuit breaker to be processed from the conveyor belt to directly below the fixed base, and the second push plate can push the circuit breaker with rivets placed to the conveyor belt. When the circuit breaker is pushed to directly below the fixed base by the first push plate, the position of the through-pin tube corresponds to the position of the mounting hole on the circuit breaker. The riveting device includes a fixed frame connected to the equipment base, a riveting pressure plate slidably connected to the fixed frame, a third hydraulic cylinder for driving the riveting pressure plate to move vertically, a third push plate slidably connected to the equipment base, a fourth hydraulic cylinder for driving the third push plate to move, a fourth push plate slidably connected to the equipment base, and a fifth hydraulic cylinder for driving the fourth push plate to move. The third push plate can push the circuit breaker from the conveyor belt to directly below the riveting pressure plate, and the fourth push plate can push the circuit breaker to the conveyor belt. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the fourth hydraulic cylinder, the fifth hydraulic cylinder, the drive motor, the first rotary feed plate, and the electric switching switch.

[0005] Using the above technical solution, firstly, the circuit breaker to be processed is placed on a conveyor belt. Then, the controller controls the drive motor to move the conveyor belt, causing the circuit breaker to move to the corresponding position of the first push plate. Next, the controller controls the first hydraulic cylinder to move the first push plate horizontally, causing the circuit breaker to be processed to move directly below the fixed base. The rivet enters the rivet tube through the first rotating feed disc. Then, the controller controls the electric switching switch to be in the closed state, allowing the rivet to enter the mounting hole of the circuit breaker. Then, the controller controls the electric switching switch to be in the closed state, and then controls the second hydraulic cylinder... The second pusher plate moves and pushes the circuit breaker back onto the conveyor belt. The conveyor belt then drives the circuit breaker to continue moving. When the circuit breaker reaches the corresponding position of the riveting plate, the controller controls the fourth hydraulic cylinder to drive the third pusher plate to push the circuit breaker directly under the riveting plate. The controller then controls the third hydraulic cylinder to press down the riveting plate, thus completing the riveting process between the rivet and the circuit breaker. Finally, the controller controls the fifth hydraulic cylinder to drive the fourth pusher plate, thus pushing the circuit breaker onto the conveyor belt to complete the unloading process. Compared with the traditional method of riveting circuit breakers with pins, this method greatly improves the level of automation and reduces labor costs.

[0006] A further feature of this invention includes a rivet detection device, comprising a sliding base slidably connected to the equipment base, a sixth hydraulic cylinder for driving the sliding base to move vertically, a plurality of probe rods slidably connected to the sliding base, a photoelectric sensor connected to the sliding base, a fifth push plate slidably connected to the equipment base, and a seventh hydraulic cylinder for driving the fifth push plate to move. The movement direction of the fifth push plate is the direction of the line connecting the sliding base and the fixed base. When the circuit breaker is located directly below the sliding base, the positions of the probe rods correspond one-to-one with the positions of the mounting holes on the circuit breaker. The controller is electrically connected to the photoelectric sensor, the sixth hydraulic cylinder, and the seventh hydraulic cylinder.

[0007] Using the above technical solution, after the circuit breaker completes the riveting work below the fixed base, the controller controls the seventh hydraulic cylinder to drive the fifth push plate to move horizontally, so that the circuit breaker moves to directly below the sliding base. At this time, the mounting holes on the circuit breaker correspond one-to-one with the positions of the detection rods. Then, the controller controls the sixth hydraulic cylinder to drive the sliding base to move vertically downward, so that the detection rod extends into the mounting hole of the circuit breaker. If there is a rivet in the mounting hole, the detection rod will be pushed up by the rivet, thus blocking the light signal emitted by the photoelectric sensor. After the photoelectric sensor detects this, it sends an electrical signal to the controller, indicating that the rivets in the mounting holes of the circuit breaker are all in place, and the equipment continues to operate normally. If there is a situation where the rivet is not properly placed in the mounting hole of the circuit breaker, the detection rod will not be pushed up by the rivet when it is pressed down, and the relative position of the detection rod and the photoelectric sensor will not change. The photoelectric sensor then sends an electrical signal to the controller, and the controller controls the equipment to stop working, waiting for the staff to come and inspect and remove the defective products. This can greatly improve the qualification rate of the products processed by this device.

[0008] A further feature of this invention includes an automatic material ejection device, which comprises a connecting frame connected to the equipment base, a limiting baffle slidably connected to the connecting frame, an eighth hydraulic cylinder for driving the limiting baffle to move vertically, a sixth push plate slidably connected to the equipment base, a ninth hydraulic cylinder for driving the sixth push plate to move horizontally, and a defective product collection frame connected to the equipment base. The limiting baffle is located directly above the conveyor belt, and the movement direction of the sixth push plate is towards the defective product collection frame. The controller is electrically connected to the eighth and ninth hydraulic cylinders respectively.

[0009] Using the above technical solution, when the photoelectric sensor and detection rod detect that there are no rivets or the rivets are not installed properly in the mounting holes of the circuit breaker, the controller controls the eighth hydraulic cylinder to drive the limit baffle to move vertically downward, so that the limit baffle contacts the upper surface of the conveyor belt, thereby blocking the circuit breaker from passing through. Then, the controller controls the ninth hydraulic cylinder to drive the sixth push plate to push the corresponding defective circuit breaker on the conveyor belt to the defective collection box, completing the automatic material removal work. This can further improve the automation level of the equipment and increase the qualification rate of the processed products.

[0010] Further features of this invention include an automatic positioning device, comprising a rotating base connected to the equipment base, a rotary motor for driving the rotating base to rotate, a seventh push plate slidably connected to the equipment base, and a tenth hydraulic cylinder for driving the seventh push plate to move horizontally. The movement direction of the seventh push plate is the line connecting the riveting pressure plate and the rotating base, and the movement direction of the fourth push plate is the line connecting the rotating base to the conveyor belt. The movement directions of the seventh push plate and the fourth push plate form a 90-degree angle. The rotating base is provided with a limiting groove, the width of which is adapted to the width of the circuit breaker to be processed. The controller is electrically connected to the tenth hydraulic cylinder and the rotary motor respectively. Using the above technical solution, after the circuit breaker completes the riveting work, the controller controls the tenth hydraulic cylinder to drive the seventh push plate to push the circuit breaker located directly below the riveting pressure plate towards the rotating base. Then, the rotating motor drives the rotating base to rotate 90 degrees, and the fifth hydraulic cylinder drives the fourth push plate to push the circuit breaker on the rotating base back to the conveyor belt. This can complete the position adjustment of the circuit breaker, ensuring that the position of the processed circuit breaker remains consistent, so as to facilitate the subsequent rapid completion of the tray-swing work, thereby further improving the processing efficiency.

[0015] like Figure 1-3As shown, an automatic rivet-feeding device for circuit breakers includes a base 1, a rivet feeding device 2 connected to the base 1, a circuit breaker feeding device 3 connected to the base 1, a pressing device 4 connected to the base 1, and a controller 5. The rivet feeding device 2 includes a first rotating feed plate 6 connected to the base 1, a plurality of connecting pipes 7 connected to the first rotating feed plate 6, a fixed base 8 connected to the base 1, a plurality of rivet-feeding pipes 9 connected to the fixed base 8, and an electric switching switch 10 connected to the rivet-feeding pipes 9. The connecting pipes 7, the rivet-feeding pipes 9, and the electric switching switch are... The number of 10 is the same. When the electric switching switch 10 is in the open state, the electric switching switch 10 can block the through-pin tube 9. When the electric switching switch 10 is in the closed state, the rivet can pass through the through-pin tube 9. The circuit breaker feeding device 3 includes a conveyor belt 11 connected to the equipment base 1, a drive motor 12 for driving the conveyor belt 11, a first push plate 13 slidably connected to the equipment base 1, a first hydraulic cylinder 14 for driving the first push plate 13, a second push plate 15 slidably connected to the equipment base 1, and a second hydraulic cylinder 16 for driving the second push plate 15. The first push plate 13 can push the circuit breaker to be processed from the conveyor belt 11 to directly below the fixed base 8. The second push plate can push the circuit breaker with rivets placed to the conveyor belt 11. When the circuit breaker is pushed to directly below the fixed base 8 by the first push plate 13, the position of the through-pin tube 9 corresponds to the position of the mounting hole on the circuit breaker. The riveting device 4 includes a fixed frame 17 connected to the equipment base 1, a riveting pressure plate 18 slidably connected to the fixed frame 17, a third hydraulic cylinder 19 for driving the riveting pressure plate 18 to move in the vertical direction, and a third push plate 20 slidably connected to the equipment base 1. The system includes a fourth hydraulic cylinder 21 for driving the third push plate 20, a fourth push plate 22 slidably connected to the equipment base 1, and a fifth hydraulic cylinder 23 for driving the fourth push plate 22. The third push plate 20 can push the circuit breaker from the conveyor belt 11 to directly below the riveting pressure plate 18, and the fourth push plate 22 can push the circuit breaker towards the conveyor belt 11. The controller 5 is electrically connected to the first hydraulic cylinder 14, the second hydraulic cylinder 16, the third hydraulic cylinder 19, the fourth hydraulic cylinder 21, the fifth hydraulic cylinder 23, the drive motor 12, the first rotating feed plate 6, and the electric switching switch 10.

[0016] First, the circuit breaker to be processed is placed on the conveyor belt 11. Then, the controller 5 controls the drive motor 12 to move the conveyor belt 11, causing the circuit breaker to move to the corresponding position of the first push plate 13. Next, the controller 5 controls the first hydraulic cylinder 14 to move the first push plate 13 horizontally, causing the circuit breaker to move directly below the fixed base 8. The rivet enters the rivet tube 9 through the first rotating feed disc 6. Then, the controller 5 controls the electric switching switch 10 to be in the closed state, allowing the rivet to enter the mounting hole of the circuit breaker. The controller 5 then controls the electric switching switch 10 to be in the closed state, and finally, the controller 5 controls the second hydraulic cylinder 16 to move the second push plate 13. The plate 15 moves and pushes the circuit breaker, after it has been placed, back onto the conveyor belt 11. Then, the circuit breaker continues to move via the conveyor belt 11. When the circuit breaker moves to the corresponding position of the riveting plate 18, the controller 5 controls the fourth hydraulic cylinder 21 to drive the third push plate 20 to push the circuit breaker directly under the riveting plate 18. Then, the controller 5 controls the third hydraulic cylinder 19 to drive the riveting plate 18 to press down, thereby completing the riveting process between the rivet and the circuit breaker. Then, the controller 5 controls the fifth hydraulic cylinder 23 to drive the fourth push plate 22, thereby pushing the circuit breaker onto the conveyor belt 11 to complete the unloading process. Compared with the traditional method of riveting circuit breakers with pins, this method greatly improves the degree of automation and reduces labor costs.

[0017] It also includes a rivet detection device 24, which includes a sliding base 25 slidably connected to the equipment base 1, a sixth hydraulic cylinder 26 for driving the sliding base 25 to move vertically, a plurality of probe rods 27 slidably connected to the sliding base 25, a photoelectric sensor 28 connected to the sliding base 25, a fifth push plate 29 slidably connected to the equipment base 1, and a seventh hydraulic cylinder 30 for driving the fifth push plate 29 to move. The movement direction of the fifth push plate 29 is the direction of the line connecting the sliding base 25 to the fixed base 8. When the circuit breaker is located directly below the sliding base 25, the positions of the probe rods 27 correspond one-to-one with the positions of the mounting holes on the circuit breaker. The controller 5 is electrically connected to the photoelectric sensor 28, the sixth hydraulic cylinder 26, and the seventh hydraulic cylinder 30.

[0018] After the circuit breaker completes the riveting process below the fixed base 8, the controller 5 controls the seventh hydraulic cylinder 30 to move the fifth push plate 29 horizontally, causing the circuit breaker to move directly below the sliding base 25. At this point, the mounting holes on the circuit breaker correspond one-to-one with the positions of the detection rod 27. Then, the controller 5 controls the sixth hydraulic cylinder 26 to move the sliding base 25 vertically downward, causing the detection rod 27 to extend into the mounting hole of the circuit breaker. If there are rivets in the mounting hole, the detection rod 27 will be pushed up by the rivets, thereby blocking the light signal emitted by the photoelectric sensor 28. After the photoelectric sensor 28 detects the fault, it sends an electrical signal to the controller 5, indicating that the rivets in the circuit breaker's mounting holes are in place. The equipment continues to operate normally. If there are rivets that are not properly placed in the circuit breaker's mounting holes, the probe rod 27 will not be pushed up by the rivets when it is pressed down. The relative position of the probe rod 27 and the photoelectric sensor 28 will not change. The photoelectric sensor 28 will then send an electrical signal to the controller 5, and the controller 5 will stop the equipment from working, waiting for staff to come and inspect and remove defective products. This can greatly improve the pass rate of products processed by this device.

The controller 5 is electrically connected to the eighth hydraulic cylinder 34 and the ninth hydraulic cylinder 36 respectively. When the photoelectric sensor 28 and the detection rod 27 detect that there are no rivets in the mounting holes of the circuit breaker or that the rivets are not installed properly, the controller 5 controls the eighth hydraulic cylinder 34 to drive the limit baffle 33 to move vertically downward, so that the limit baffle 33 contacts the upper surface of the conveyor belt 11, thereby blocking the circuit breaker from passing through. Then, the controller controls the ninth hydraulic cylinder 36 to drive the sixth push plate 35 to push the corresponding defective circuit breaker on the conveyor belt 11 towards the defective collection box 37, completing the automatic material kicking operation. This can further improve the automation level of the equipment and increase the qualification rate of the processed products.

[0020] It also includes an automatic positioning device 38, which includes a rotating base 39 connected to the equipment base 1, a rotary motor 40 for driving the rotating base 39 to rotate, a seventh push plate 41 slidably connected to the equipment base 1, and a tenth hydraulic cylinder 42 for driving the seventh push plate 41 to move in the horizontal direction. The movement direction of the seventh push plate 41 is the line connecting the riveting pressure plate 18 and the rotating base 39, and the movement direction of the fourth push plate 22 is the line connecting the rotating base 39 to the conveyor belt 11. The movement directions of the seventh push plate 41 and the fourth push plate 22 form a 90-degree angle. The rotating base 39 is provided with a limiting groove 43, the width of which is adapted to the width of the circuit breaker to be processed. The controller 5 is electrically connected to the tenth hydraulic cylinder 42 and the rotary motor 40 respectively.

[0021] After the circuit breaker has completed the riveting process, the controller 5 controls the tenth hydraulic cylinder 42 to drive the seventh push plate 41 to push the circuit breaker located directly below the riveting pressure plate 18 towards the rotating base 39. Then, the rotary motor 40 drives the rotating base 39 to rotate 90 degrees. The fifth hydraulic cylinder 23 then drives the fourth push plate 22 to push the circuit breaker on the rotating base 39 back to the conveyor belt 11. This completes the position adjustment of the circuit breaker, ensuring that the position of the processed circuit breaker remains consistent, so as to facilitate the subsequent rapid completion of the tray-swing work and further improve the processing efficiency.
