Description

Technical Field

[0001] This utility model relates to a silver dot feeding and picking device. Background Technology

[0002] like Figure 6 As shown, the circuit breaker silver point 49 includes a silver point contact part 50 and a silver point riveting part 51. In the mass assembly process of the silver point contact plate, the circuit breaker silver point 49 is generally transmitted to the silver point feeding assembly through a silver point vibratory feeder. Since the circuit breaker silver points 49 are driven one after another when they are transmitted with the vibratory feeder, this close arrangement lacks a certain interval buffer, resulting in a large mutual influence between the silver points. During the process of the silver point feeding assembly driving a single circuit breaker silver point 49 for conveying, the squeezing of the rear circuit breaker silver point 49 can easily cause jamming at the docking point between the silver point feeding assembly and the circuit breaker silver point 49 during conveying, causing the circuit breaker silver point 49 to deform or be damaged. Frequent maintenance of the silver point feeding results in low assembly efficiency. Improvements and optimizations are made to address this issue. Utility Model Content

[0004] The technical solution adopted by the silver dot feeding and picking device of this utility model is characterized by comprising a device base plate, a silver dot vibratory feeder for arranging and transmitting silver dots in a circuit breaker, a silver dot feeding assembly disposed on the device base plate, and a silver dot picking assembly for picking up the silver dots in the circuit breaker. The silver dot feeding assembly includes a feeding receiving block, a feeding cylinder, and a silver dot driving rod whose end is connected to the output end of the feeding cylinder. The upper end of the feeding receiving block is provided with a silver dot contact receiving groove that is horizontally arranged and horizontally connected to the outlet end of the silver dot vibratory feeder. The bottom of the silver dot contact receiving groove is provided with a silver dot riveting part positioning groove for positioning the silver dot riveting part.

[0008] Both the limiting part of the driving rod and the receiving part of the driving rod are square structures.

[0009] The advantages of this utility model silver point feeding and picking device are: the silver point front guide block and the silver point rear guide block are staggered, which eliminates the mutual squeezing and jamming between the circuit breaker silver points, effectively avoids the jamming caused by the transmission squeezing of the circuit breaker silver points at the connection point of the circuit breaker silver point feeding and the damage to the circuit breaker silver points, thus improving the feeding efficiency and feeding stability.

[0017] like Figures 1-6As shown, the silver dot feeding and picking device of this utility model includes a device base plate 1, a silver dot vibratory feeder 2 for arranging and transmitting silver dots 49 of the circuit breaker, a silver dot feeding assembly 3 mounted on the device base plate 1, and a silver dot picking assembly 4 for picking up the silver dots 49 of the circuit breaker. The silver dot feeding assembly 3 includes a feeding receiving block 6, a feeding cylinder 8, and a silver dot driving rod 7 whose end is connected to the output end of the feeding cylinder 8. The upper end of the feeding receiving block 6 is provided with a silver dot contact receiving groove 12 that is horizontally arranged and horizontally connected to the outlet end of the silver dot vibratory feeder 2. The bottom of the silver dot contact receiving groove 12 is provided with a positioning part for the silver dot riveting part 51. The silver dot riveting part positioning groove 13, the front left side wall of the silver dot contact part receiving groove 12 and the front left side wall of the silver dot riveting part positioning groove 13 are both provided with silver dot leading blocks 14 for driving the circuit breaker silver dot 49 to shift to the right. The rear right side wall of the silver dot contact part receiving groove 12 and the rear right side wall of the silver dot riveting part positioning groove 13 are both provided with silver dot rear leading blocks 15 for driving the circuit breaker silver dot 49 to shift to the left. The silver dot leading blocks 14 and silver dot rear leading blocks 15 are staggered. The silver dot leading blocks 14 and silver dot rear leading blocks 15 are the same size. The length of the silver dot leading block 14 is equal to that of the silver dot contact part 50. With the same outer diameter, the silver dot driving rod 7 includes a driving rod limiting part 16 and a driving rod receiving part 17 located at the upper end of the driving rod limiting part 16. The driving rod receiving part 17 is provided with an upper driving rod receiving groove 18 that connects to the rear end of the silver dot contact part receiving groove 12 and a lower driving rod positioning groove 19 that connects to the rear end of the silver dot riveting part positioning groove 13. The feeding receiving block 6 is provided with a longitudinally arranged feeding receiving block limiting port 21 for limiting the driving rod limiting part 16 and a feeding receiving block clearance port 22 that communicates with the rear end of the silver dot riveting part positioning groove 13 and is used for positioning the driving rod receiving part 17. The silver dot guide block 14 and The staggered arrangement of the silver point guide blocks 15 ensures that only two staggered circuit breaker silver points 49 are present on the positioning groove 13 of the silver point riveting part at the same time. When the feeding receiving block limit port 21 on the silver point driving rod 7 connects with the rear end of the positioning groove 13 of the silver point riveting part, the individual staggered action of the silver point front guide block 14 and the silver point rear guide block 15 prevents the circuit breaker silver points 49 from experiencing excessive squeezing force. This allows the circuit breaker silver points 49 to enter the silver point driving rod 7 more smoothly and effectively avoids the jamming and damage of the circuit breaker silver points 49 at the connection between the silver point driving rod 7 and the positioning groove 13 of the silver point riveting part, thereby improving feeding efficiency and feeding stability.

[0018] Both the front end of the silver point guide block 14 and the front end of the silver point guide block 15 are provided with guide block transition surfaces 24 to facilitate the transmission of the circuit breaker silver point 49. This ensures that the circuit breaker silver point 49 can smoothly and seamlessly transmit power from the silver point vibrating plate 2 to the front end of the silver point riveting part positioning groove 13 and from the front end of the silver point riveting part positioning groove 13 to the rear end of the silver point riveting part positioning groove 13, ensuring a one-to-one correspondence and improving transmission stability and reliability.

[0019] The silver point feeding assembly 3 also includes a suction rod 9 connected to a vacuum pump. The feeding receiving block 6 has a suction rod adsorption port 25 at the feeding receiving block clearance port 22, which is opposite to the rear end of the silver point riveting part positioning groove 13. The suction rod 9 is placed in the suction rod adsorption port 25. The suction rod 9 quickly adsorbs the circuit breaker silver point 49 at the rear end of the silver point riveting part positioning groove 13 onto the silver point driving rod 7 by suction. When the circuit breaker silver point 49 is transmitted from the rear end of the silver point riveting part positioning groove 13 to the silver point driving rod 7, the adsorption force makes the transmission faster and more accurate, further improving the accuracy and stability of the transmission.

[0020] The silver dot feeding assembly 3 also includes a protective plate 10 fixed on the feeding receiving block 6 and used to cover the positioning groove 13 of the silver dot riveting part, to prevent dust from entering and causing the circuit breaker silver dot 49 to be unable to move smoothly, and has good protection.

[0021] Both the driving rod limiting part 16 and the driving rod receiving part 17 are square structures, making the operation more reliable.

[0022] 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.
