Description

Technical Field

[0001] This application relates to the field of solid-state relay manufacturing technology, and in particular to a feeding mechanism for solid-state relay manufacturing. Background Technology

[0002] Solid-state relays are contactless switches composed of solid-state electronic components such as microelectronic circuits, discrete electronic devices, and power electronic devices. Isolation devices are used to isolate the control terminal from the load terminal. Solid-state relays provide both amplification and isolation, making them well-suited for driving high-power switching actuators. Compared to electromagnetic relays, they offer higher reliability, are contactless, have a long lifespan, high speed, and are less susceptible to external interference, leading to their widespread application.

[0003] After solid-state relays are manufactured, to ensure their quality before leaving the factory, they need to undergo appearance inspection and performance testing sequentially. In related technologies, before testing the manufactured solid-state relays, a conveyor belt is typically used to transport them to the appearance inspection equipment. Workers then remove the solid-state relays and place them on the appearance inspection table. After the appearance inspection is completed, workers remove the solid-state relays and place them on another conveyor belt, which transports them to the performance testing equipment. Workers then remove the solid-state relays and place them on the performance testing table. After the performance testing is completed, workers remove the solid-state relays and place them on a third conveyor belt for further transport. This method of transferring and feeding solid-state relays is cumbersome and time-consuming, increasing manual operation steps and workload, resulting in relatively low work efficiency.

[0004] Therefore, we propose a feeding mechanism for solid-state relay production to solve the above problems. Utility Model Content

The driving assembly is disposed within the installation groove and is used to control the rotation of the column.

[0009] A further provision of this application is that the diameter of the disk is larger than the inner diameter of the mounting groove.

[0024] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] See Figures 1-5 This application provides a feeding mechanism for solid-state relay production, including a feeding platform 1. A first conveyor frame 2, a solid-state relay appearance inspection platform 3, a solid-state relay performance inspection platform 4, and a second conveyor frame 5 are fixedly mounted on the feeding platform 1. The first conveyor frame 2, the solid-state relay appearance inspection platform 3, the solid-state relay performance inspection platform 4, and the second conveyor frame 5 are arranged in a ring with equal spacing around the feeding platform 1. A first conveyor belt 6 is rotatably mounted on the first conveyor frame 2, used to convey the solid-state relays towards the feeding platform 1. A second conveyor belt 7 is rotatably mounted on the second conveyor frame 5, used to convey the solid-state relays away from the feeding platform 1. Appearance inspection equipment can be placed on the solid-state relay appearance inspection platform 3 to facilitate visual inspection of the solid-state relays by personnel. Performance inspection equipment can be placed on the solid-state relay performance inspection platform 4 to facilitate performance testing of the solid-state relays by personnel.

[0026] The feeding platform 1 is equipped with a feeding and transfer mechanism for transferring solid-state relays. This mechanism includes a shaft seat 9, a column 10, a disc 11, an electric guide rail 12, an electric slide 13, a connecting seat 14, a U-shaped frame 15, a clamping and fixing assembly, and a drive assembly. The top of the feeding platform 1 has a mounting groove 8. The shaft seat 9 is fixedly installed on the bottom inner wall of the mounting groove 8. The column 10 is rotatably installed on the top of the shaft seat 9. The disc 11 is fixedly installed on the top of the column 10, with its bottom slidably contacting the top of the feeding platform 1. The electric guide rail 12 is fixedly installed on the top of the disc 11. The electric slide 13 is slidably installed on the electric guide rail 12. The connecting seat 14 is fixedly installed on the top of the electric slide 13. The U-shaped frame 15 is fixedly installed on the front side wall of the connecting seat 14. The clamping and fixing component is set on the U-shaped frame 15 and is used to clamp and fix the solid-state relay. The drive component is set in the mounting groove 8 and is used to control the rotation of the column 10. By using the electric slide 13 to slide horizontally on the electric guide rail 12, the U-shaped frame 15 and the clamping and fixing component can be driven to move horizontally in a straight line through the connecting seat 14. It should be noted that the upper surface of the first conveyor belt 6 and the upper surface of the second conveyor belt 7 are both slightly higher than the upper surface of the electric guide rail 12. Therefore, during the transfer of the solid-state relay, the bottom of the solid-state relay will not touch the electric guide rail 12, ensuring that the transfer and feeding operation is carried out smoothly.

[0027] In this embodiment, the clamping and fixing assembly includes two electric telescopic rods 16, two clamping plates 17, and two protective pads 18. The two electric telescopic rods 16 are respectively fixedly installed on the outer walls of both sides of the U-shaped frame 15. The two clamping plates 17 are respectively fixedly installed on the output shaft ends of the corresponding electric telescopic rods 16. The two protective pads 18 are respectively fixedly installed on the sides of the two clamping plates 17 that are close to each other. Utilizing the telescopic feature of the two electric telescopic rods 16, the distance between the two clamping plates 17 can be adjusted. The combined action of the two clamping plates 17 can effectively clamp and fix the solid-state relay. The two protective pads 18 can protect the clamping parts of the solid-state relay, preventing damage to the solid-state relay due to excessive clamping force. It should be noted that the protective pads 18 can be made of rubber or silicone. The driving assembly includes a motor 19, a drive gear 20, and a slave gear. The driving gear 21 and PLC controller 22, as well as the motor 19 and PLC controller 22, are all fixedly installed on the bottom inner wall of the mounting slot 8. The driving gear 20 is fixedly installed on the output shaft end of the motor 19, and the driven gear 21 is fixedly mounted on the column 10. The driving gear 20 meshes with the driven gear 21. The PLC controller 22 is electrically connected to the motor 19. The motor 19 can control the rotation of the driving gear 20. The meshing transmission action of the driving gear 20 and the driven gear 21 can control the horizontal rotation of the column 10, the disc 11, and the clamped solid-state relay. The PLC controller 22 can control the output shaft of the motor 19 to rotate 90 degrees each time it runs. It should be noted that the control circuit of the PLC controller 22 can be implemented by those skilled in the art through simple programming, and it belongs to the mature technology in this field. Therefore, it will not be described in detail here.

[0028] In this embodiment, in order to ensure smooth clamping, fixing and transfer of the solid-state relay, the upper surface of the first conveyor belt 6 is higher than the upper surface of the first conveyor frame 2, the upper surface of the second conveyor belt 7 is higher than the upper surface of the second conveyor frame 5, and the upper surfaces of both the first conveyor belt 6 and the second conveyor belt 7 are higher than the upper surface of the feeding table 1.

[0029] In this embodiment, the diameter of the disc 11 is larger than the inner diameter of the mounting groove 8, which can completely cover the opening of the mounting groove 8 and prevent dust, debris and other impurities from entering the mounting groove 8.

[0030] In this embodiment, in order to ensure that the motor 19 can control the column 10 to rotate 90 degrees each time it runs, the diameter of the driving gear 20 and the diameter of the driven gear 21 are set to be the same.

[0031] In this embodiment, a U-shaped plate 23 is fixedly installed on the top of the first conveyor frame 2, an air pump 24 is fixedly installed on the outer right side of the U-shaped plate 23, and an air supply pipe 25 is fixedly installed on the inner top of the U-shaped plate 23. One end of the air supply pipe 25 is fixedly connected to the exhaust end of the air pump 24, and multiple jet nozzles 26 are fixedly connected at equal intervals on the air supply pipe 25. By utilizing the pressurization effect generated by the energized operation of the air pump 24, pressurized air can be controlled to spray vertically downward from the multiple jet nozzles 26. When the first conveyor belt 6 transports the solid-state relay to the area below the multiple jet nozzles 26, the sprayed pressurized air can blow away dust, debris, and other impurities on the surface of the solid-state relay, thereby ensuring the accuracy of the subsequent appearance inspection and performance test results of the solid-state relay.

[0032] With the above structure, the feeding mechanism for solid-state relay production provided in this application can clamp and fix the solid-state relays conveyed from the first conveyor belt 6 and transfer them sequentially to the solid-state relay appearance inspection table 3, the solid-state relay performance inspection table 4, and the second conveyor belt 7, thus achieving the purpose of automatic transfer and feeding. This facilitates the sequential appearance inspection and performance inspection of the solid-state relays and the conveying of the inspected solid-state relays, reducing manual operation steps and workload, and improving work efficiency.In specific operation, the manufactured solid-state relays are placed at intervals on the first conveyor belt 6. The first conveyor belt 6 can be used to transport the solid-state relays towards the feeding table 1. During the transport process, by controlling the operation of the air pump 24, pressurized air can be sprayed vertically downward from multiple jet nozzles 26. When the solid-state relays are transported to the area below the multiple jet nozzles 26, the sprayed pressurized air can blow away dust, debris, and other impurities on the surface of the solid-state relays, thereby ensuring the accuracy of subsequent appearance and performance testing results. Furthermore, during the transport process, by controlling the electric slide 13 to slide forward linearly on the electric guide rail 12, the U-shaped frame 15 can be moved forward to the first conveyor belt 1. Directly above conveyor belt 6, when the first conveyor belt 6 transports the solid-state relay to a position close to the feeding table 1, the solid-state relay enters between the two protective pads 18 inside the U-shaped frame 15. Then, by controlling the two electric telescopic rods 16 to extend until the two protective pads 18 are firmly in contact with the side walls of the solid-state relay, the solid-state relay is clamped and fixed. Next, the electric slide block 13 slides backward linearly on the electric guide rail 12, moving the clamped solid-state relay back above the disc 11. Then, the motor 19 runs once, and the output shaft of the motor 19 drives the drive gear 20 to rotate 90 degrees. The drive gear 20 drives the driven gear 21, column 10, disc 11, U-shaped frame 15, and the clamped solid-state relay. The solid-state relay rotates 90 degrees, at which point the opening of the U-shaped bracket 15 aligns with the solid-state relay appearance inspection platform 3. Then, the electric slide 13 slides linearly on the electric guide rail 12, moving the clamped solid-state relay above the solid-state relay appearance inspection platform 3. By controlling the two electric telescopic rods 16 to retract and reset, the clamping and fixing of the solid-state relay is released, allowing for appearance inspection. After the appearance inspection is completed, the solid-state relay is clamped and fixed again following the above steps and moved back above the disc 11. Then, the motor 19 is run once more to move the clamped solid-state relay above the solid-state relay performance inspection platform 4. The clamping and fixing of the solid-state relay is then released, allowing for further inspection. After the solid-state relay is tested, it is clamped and fixed again according to the above operation steps and moved back above the disc 11. The motor 19 is run once more to transfer the clamped solid-state relay to the second conveyor belt 7. The clamped solid-state relay is then released and transported away by the second conveyor belt 7. The motor 19 is run once more to align the opening of the U-shaped frame 15 with the first conveyor belt 6. This completes the automatic transfer feeding process of clamping and fixing the solid-state relay transported from the first conveyor belt 6 and sequentially transferring it to the solid-state relay appearance inspection table 3, the solid-state relay performance inspection table 4, and the second conveyor belt 7.
