Description

Technical Field

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

[0002] Circuit breakers are commonly used switching devices in daily life. The handle component is a crucial part of the circuit breaker, primarily responsible for controlling the closing and opening of the circuit breaker to ensure the normal operation of the power system. Currently, this process is typically completed manually. However, manual assembly suffers from low efficiency, high labor costs, and difficulty in meeting the demands of mass production. Automated assembly presents the following problems: First, the irregular shape of the handle makes assembly difficult, making accurate installation challenging. Second, during the loading process, handle components may collide with each other, causing positional shifts and hindering accurate subsequent installation. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an automatic circuit breaker handle feeding device that features a high degree of automation, improved assembly efficiency, and ensures accurate feeding of handle components. The technical solution of this utility model is as follows: An automatic circuit breaker handle feeding device includes a base, a transmission device connected to the base, a clamping device connected to the base, and a controller connected to the base. The transmission device includes a rotary vibrating feed plate connected to the base, a transmission track connected to the rotary vibrating feed plate, a vibrating motor connected to the transmission track, and a baffle plate connected to the end of the transmission track. The clamping device includes a fixed frame connected to the base, a first sliding base slidably connected to the fixed frame, a second sliding base slidably connected to the first sliding base, and a component fixedly connected to the second sliding base. The system includes a connecting base, an electric clamping jaw movably connected to the connecting base, a first hydraulic cylinder for driving the first sliding base to move horizontally, a second hydraulic cylinder for driving the second sliding base to move vertically, and a rotary motor for driving the electric clamping jaw to rotate. The movement direction of the first sliding base is parallel to the feeding direction of the transmission track. When the first sliding base is in its initial position, the electric clamping jaw is located directly above the end of the transmission track. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the electric clamping jaw, the rotary vibrating feed plate, the vibrating motor, and the rotary motor.

[0004] Using the above technical solution, firstly, the controller controls the rotating vibrating feed plate to feed the handle component to be processed onto the transmission track. Then, the vibrating motor provides vibration force to the transmission track, thereby driving the handle component in the transmission track to move towards the electric clamping jaw. When the handle component moves directly below the electric clamping jaw, the controller controls the second hydraulic cylinder to drive the second sliding base to move vertically downward, and the controller controls the electric clamping jaw to clamp the handle component. Then, the first and second hydraulic cylinders drive the electric clamping jaw to move directly above the fixed station, and the rotary motor controls the electric clamping jaw to rotate a certain angle, so that the position of the handle component corresponds to the position to be assembled on the fixed station. Finally, the controller controls the electric clamping jaw to release the handle component, allowing the handle component to be accurately placed into the fixed station. This achieves automated loading of the handle component, greatly reducing labor costs.

[0005] A further feature of this invention is that there are two transmission tracks and two electric clamping claws. When the first sliding base is in the initial position, the two electric clamping claws correspond to the positions of the two transmission tracks respectively.

[0006] By adopting the above technical solution, since there are two transmission tracks and two electric clamping claws, two handle components can be clamped at once to complete the loading, further improving work efficiency. A further feature of this invention is that the baffle plate is provided with a limiting groove, which is adapted to the shape and size of the handle component to be processed.

[0007] By adopting the above technical solution, since the baffle plate is provided with a limiting groove, when the handle component moves to the end of the transmission track, the handle component in front is pushed into the limiting groove by the handle component in back. Since the limiting groove is adapted to the shape and size of the handle component to be processed, the positional stability of the handle component can be guaranteed, thereby ensuring the accurate loading position of the handle component after it is clamped.

[0008] A further feature of this invention is that the equipment base is also provided with an infrared emitting element and an infrared receiving element connected to the equipment base. The infrared signal emitted by the infrared emitting element corresponds to the end position of the transmission track, and the direction of the infrared signal emitted by the infrared emitting element is perpendicular to the feeding direction of the transmission track. The infrared receiving element is electrically connected to the controller.

[0009] By adopting the above technical solution, since the infrared signal emitted by the infrared emitting element corresponds to the end position of the transmission track, when the handle component moves to the end of the transmission track, the infrared signal emitted by the infrared emitting element will be blocked by the handle component, and the infrared receiving element will not receive the infrared signal. The infrared receiving element sends an electrical signal to the controller, and the controller controls the electric clamping jaws to clamp the handle component, which can further improve the accuracy of the handle component loading.

[0010] Further features of this invention include a third sliding base slidably connected to the equipment base, a limiting baffle connected to the third sliding base, and a third hydraulic cylinder for driving the third sliding base to move vertically. The limiting baffle is L-shaped and located directly above the transmission track. When the third sliding base slides vertically downwards a certain distance, the bottom of the limiting baffle contacts the transmission track and the handle element to be processed, respectively. The controller is electrically connected to the third hydraulic cylinder.

[0011] Using the above technical solution, when the infrared receiving element sends an electrical signal to the controller, the controller controls the third hydraulic cylinder to drive the third sliding base to move vertically downward, thereby causing the limiting baffle to press down. Since the limiting baffle is L-shaped, and after the third sliding base slides vertically downward a certain distance, the bottom of the limiting baffle contacts the transmission track and the handle component to be processed respectively. Therefore, it can ensure that the position of the handle component to be processed on the transmission track is stable and will not squeeze the handle component located at the front, thereby ensuring the stability of the position of the handle component to be clamped and improving the accuracy of the handle component loading.

Detailed Implementation

[0016] like Figure 1-3 As shown, an automatic feeding device for circuit breaker handles includes a base 1, a transmission device 2 connected to the base 1, a clamping device 3 connected to the base 1, and a controller 4 connected to the base 1. The transmission device 2 includes a rotary vibrating feed plate 5 connected to the base 1, a transmission track 6 connected to the rotary vibrating feed plate 5, a vibrating motor 7 connected to the transmission track 6, and a baffle plate 8 connected to the end of the transmission track 6. The clamping device 3 includes a fixed frame 9 connected to the base 1, a first sliding base 10 slidably connected to the fixed frame 9, a second sliding base 11 slidably connected to the first sliding base 10, and a connecting base 12 fixedly connected to the second sliding base 11. The electric clamping jaw 13 is movably connected to the connecting base 12, the first hydraulic cylinder 14 for driving the first sliding base 10 to move horizontally, the second hydraulic cylinder 15 for driving the second sliding base 11 to move vertically, and the rotary motor 16 for driving the electric clamping jaw 13 to rotate. The movement direction of the first sliding base 10 is parallel to the feeding direction of the transmission track 6. When the first sliding base 10 is in the initial position, the electric clamping jaw 13 is located directly above the end of the transmission track 6. The controller 4 is electrically connected to the first hydraulic cylinder 14, the second hydraulic cylinder 15, the electric clamping jaw 13, the rotary vibrating feed plate 5, the flat vibrating motor 7, and the rotary motor 16.

[0017] First, the controller 4 controls the rotating vibrating feed plate 5 to feed the handle component to be processed onto the transmission track 6. Then, the flat vibrating motor 7 provides vibration force to the transmission track 6, thereby driving the handle component in the transmission track 6 to move towards the electric clamping jaw 13. When the handle component moves directly below the electric clamping jaw 13, the controller 4 controls the second hydraulic cylinder 15 to drive the second sliding base 11 to move vertically downward, and the controller 4 controls the electric clamping jaw 13 to clamp the handle component. Then, the first hydraulic cylinder 14 and the second hydraulic cylinder 15 drive the electric clamping jaw 13 to move directly above the fixed station, and the rotary motor 16 controls the electric clamping jaw 13 to rotate a certain angle, so that the position of the handle component corresponds to the position to be assembled on the fixed station. Then, the controller 4 controls the electric clamping jaw 13 to release the handle component, so that the handle component is accurately placed into the fixed station. In this way, the loading of the handle component is automated, which greatly reduces labor costs. The number of transmission rails 6 and electric clamping claws 13 are both two. When the first sliding base 10 is in the initial position, the two electric clamping claws 13 correspond to the positions of the two transmission rails 6 respectively.

[0018] Since there are two of each of the transmission rail 6 and the electric clamping jaw 13, two handle components can be clamped at once to complete the loading, further improving work efficiency.

[0019] The baffle plate 8 is provided with a limiting groove 17, which is adapted to the shape and size of the handle component to be processed.

[0020] Since the baffle plate 8 is provided with a limiting groove 17, when the handle component moves to the end of the transmission track 6, the handle component in front is pushed into the limiting groove 17 by the handle component in back. Since the limiting groove 17 is adapted to the shape and size of the handle component to be processed, the positional stability of the handle component can be guaranteed, thereby ensuring that the loading position of the handle component is accurate after it is clamped.

[0021] The equipment base 1 is also provided with an infrared emitting element 18 and an infrared receiving element 19 connected to the equipment base 1. The infrared signal emitted by the infrared emitting element 18 corresponds to the end position of the transmission track 6, and the direction of the infrared signal emitted by the infrared emitting element 18 is perpendicular to the feeding direction of the transmission track 6. The infrared receiving element 19 is electrically connected to the controller 4.

[0022] Since the infrared signal emitted by the infrared emitting element 18 corresponds to the end position of the transmission track 6, when the handle component moves to the end of the transmission track 6, the infrared signal emitted by the infrared emitting element will be blocked by the handle component, and the infrared receiving element 19 will not receive the infrared signal. The infrared receiving element 19 sends an electrical signal to the controller 4, and the controller 4 controls the electric clamping jaw 13 to clamp the handle component, which can further improve the accuracy of the handle component loading.

[0023] It also includes a third sliding base 20 slidably connected to the equipment base 1, a limiting baffle 21 connected to the third sliding base 20, and a third hydraulic cylinder 22 for driving the third sliding base 20 to move vertically. The limiting baffle 21 is L-shaped and located directly above the transmission track 6. When the third sliding base 20 slides vertically downwards a certain distance, the bottom of the limiting baffle 21 contacts the transmission track 6 and the handle element to be processed, respectively. The controller 4 is electrically connected to the third hydraulic cylinder 22.

[0024] When the infrared receiving element 19 sends an electrical signal to the controller 4, the controller 4 controls the third hydraulic cylinder 22 to drive the third sliding base 20 to move vertically downward, thereby causing the limiting baffle 21 to press down. Since the limiting baffle 21 is L-shaped, and after the third sliding base 20 slides vertically downward a certain distance, the bottom of the limiting baffle 21 contacts the transmission track 6 and the handle component to be processed respectively. Therefore, it can ensure that the position of the handle component to be processed on the transmission track 6 is stable and will not squeeze the handle component located at the front, thereby ensuring the stability of the position of the handle component to be clamped and improving the accuracy of the handle component loading.
