[0002] like Figure 7 As shown, the circuit breaker silver point 49 includes a silver point contact portion 50 and a silver point riveting portion 51 located at the bottom of the silver point contact portion 50. The diameter of the silver point contact portion 50 is larger than the diameter of the silver point riveting portion 51. After the circuit breaker silver point 49 is processed, the diameter of the silver point contact portion 50 needs to be screened, and the circuit breaker silver points 49 with a diameter lower than the specified value are rejected. Since the number of circuit breaker silver points 49 produced is large, the conventional method is to manually sample and inspect or manually place the circuit breaker silver points 49 on a diameter measuring machine for full inspection and screening. This screening method is time-consuming, labor-intensive, and requires high personnel involvement. Therefore, improvements and optimizations are made to address this issue. Utility Model Content

[0019] like Figure 1-7As shown, the silver point screening and feeding device of this utility model includes a silver point vibratory plate 1 for sequentially arranging and outputting silver points 49 from a circuit breaker, a silver point transfer seat assembly 2, and a silver point diameter screening device 3. The silver point vibratory plate 1 is provided with a vibratory plate output end 4, and the vibratory plate output end 4 is provided with an output end receiving groove 5 for receiving the silver point contact part 50. The output end receiving groove 5 is provided with an output end positioning groove 6 for the silver point riveting part 51 to make way. The silver point transfer seat assembly 2 includes a transfer block 8, and the transfer block 8 includes a transversely arranged transfer block transition part 10 and a longitudinally arranged transfer block docking part in the middle of the transfer block transition part 10. 9. The transfer block docking part 9 is provided with an internal transfer block channel 11 for the vertical drop of a single circuit breaker silver point 49. The upper side wall of the internal transfer block channel 11 is provided with a transfer block interface 12 that vertically connects the output end receiving groove 5 and the output end positioning groove 6 to the internal transfer block channel 11. The bottom of the transfer block transition part 10 is provided with a lower positioning port 13 that communicates with the internal transfer block channel 11 and is used for positioning the silver point riveting part 51 after it drops. The bottom front end of the transfer block transition part 10 is provided with a transfer block channel 11 that vertically communicates with the internal transfer block channel 11 and is used for the lateral movement of a single circuit breaker silver point 49. The transfer block outlet 14 has a first L-shaped guide foot 15 and a second L-shaped guide foot 16 at its bottom. A guide foot limiting gap 16 for limiting the silver point riveting part 51 is formed between the first guide foot 15 and the second guide foot 16. The silver point diameter screening device 3 includes a first cylindrical roller 17 and a second cylindrical roller 18. A cylindrical roller measuring gap 19 for measuring the diameter of the circuit breaker silver point 49 is formed between the first cylindrical roller 17 and the second cylindrical roller 18. The transfer block outlet 14 is connected to the cylindrical roller measuring gap 19. The guide foot 15 and the second guide foot 16 are inserted into the cylindrical roller tension gap 19. The transfer block 8 enables a smooth transition of the circuit breaker silver point 49 from the vibratory feeder output end 4 to the silver point diameter screening device 3, allowing for automatic screening of circuit breaker silver points 49 of different diameters. This improves efficiency. The connecting part of the transfer block ensures that the circuit breaker silver points 49 fall from top to bottom, and the transition part of the transfer block ensures that only one circuit breaker silver point 49 moves from the transfer block 8 to the silver point diameter screening device 3 at a time. This effectively prevents screening jams and frequent maintenance caused by mutual squeezing between the circuit breaker silver points 49, thus effectively improving screening efficiency.

[0020] The silver spot diameter screening device 3 also includes a main motor 21, a main gear 22 connected to the output shaft of the main motor 21, a first gear 23 located above the main gear 22 and meshing with the main gear 22, and a second gear 24 located on the same horizontal plane as the first gear 23 and meshing with the first gear 23. The first gear 23 is sleeved on the first cylindrical roller 17, and the second gear 24 is sleeved on the second cylindrical roller 18. The device is reliable in operation and has high screening accuracy.

[0021] The internal channel 11 of the transfer block has a square structure, and its length is the same as the diameter of a single silver contact portion 50, ensuring that the single circuit breaker silver contacts 49 fall from top to bottom in a stacked manner, reducing the problem of jamming caused by internal compression.

[0022] The silver point transfer assembly 2 also includes an air nozzle 28 for blowing air into the circuit breaker silver point 49. The rear end of the transfer block transition part 10 is provided with an air nozzle mounting port 26 that is perpendicularly connected to the bottom of the transfer block inner channel 11 and is used for installing the air nozzle 28. The air nozzle 28 can speed up the transfer of the circuit breaker silver point 49 from the transfer block inner channel 11 to the transfer block outlet 14, improve efficiency and ensure stability and reliability.

[0023] The silver point transfer seat assembly 2 also includes a push column 29. The upper end of the transfer block docking part 9 is provided with a transfer block push port 30 that communicates with the inner channel 11 of the transfer block and is used for the push column 29 to push the circuit breaker silver point 49 downward. When the circuit breaker silver point 49 is stuck in the inner channel 11 of the transfer block, the push column 29 can be pushed downward slowly to accelerate the falling of the circuit breaker silver point 49, making the overall screening process smooth and convenient for maintenance.

[0024] Screening process: The circuit breaker silver points 49 are arranged in sequence on the output end 4 of the vibratory feeder 1. Under the vibration of the vibratory feeder 1, the circuit breaker silver points 49 enter the transfer block 8 through the transfer block interface 12 in sequence, and fall vertically from top to bottom to the bottom of the transfer block 8 through the internal channel 11. The silver point riveting part 51 of the circuit breaker silver points 49 is placed in the lower positioning port 13 of the transfer block. The air blowing nozzle 28 blows air onto the circuit breaker silver points 49 at the bottom, causing a single circuit breaker silver point 49 to move to the transfer block outlet 14. Due to the first L-shaped guide foot 15 and the second The L-shaped guide foot 16 guides the individual circuit breaker silver points 49 to move stably from the transfer block outlet 14 into the cylindrical drum tension gap 19. Driven by the main motor 21, the first cylindrical drum 17 and the second cylindrical drum 18 move the circuit breaker silver points 49 on the cylindrical drum tension gap 19 forward. Since the width of the cylindrical drum tension gap 19 is the specified diameter of the circuit breaker silver points 49, when the diameter of the circuit breaker silver point 49 to be tested is smaller than the cylindrical drum tension gap 19, it will fall out of the cylindrical drum tension gap 19, thereby realizing the automatic screening and feeding of the circuit breaker silver points 49.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
