Description

Technical Field

[0001] The present invention relates to the technical field of switch power supply production, and specifically to a welding mechanism for a switch power supply. Background Art

[0002] A switch power supply is a power supply that uses modern power electronics technology to control the on-off time ratio of a switch tube and maintain a stable output voltage. With the development and innovation of power electronics technology, the switch power supply technology is also constantly innovating. Switch power supplies are widely used in almost all electronic devices and are an indispensable power supply method for the rapid development of the current electronic information industry. Welding operations are required during the production and processing of switch power supplies.

[0003] A Chinese invention patent with the publication number CN115041886B discloses a welding device for a switch power supply, including a supporting bottom box. A side baffle is provided on the upper surface of the supporting bottom box, and the lower surface of the side baffle is fixedly connected to the left side of the upper surface of the supporting bottom box. The number of the side baffles is two, and a guiding side plate is fixedly connected to the middle of the inner wall of the side baffle. This device can place the installed switch power supply inside the welding plate frame externally and transport it into the upper box shell through a transport conveyor belt for welding work. Since this device separates the feeding work from the welding work, the processing and welding work of the switch power supply can be carried out synchronously, thereby effectively improving production efficiency and avoiding the problem that when a single person processes, the assembly and feeding work is required, resulting in cumbersome steps and seriously affecting the production progress. Since there is a dedicated person to feed the switch power supply, there is sufficient time to conduct quality inspection work on the switch power supply, thereby reducing the defective rate of the product.

[0004] However, the above patent still has the following deficiencies in actual use: Firstly, the operator of this patent continuously welds electrical components through a welding end. As the welding time increases, the surface temperature of the welding end will become higher and higher, and the lack of heat dissipation of the welding end will affect the welding work. Secondly, the switch power supply of this patent uses a method of one person welding and one person assembling and feeding, and cannot perform automatic continuous feeding and welding on the switch power supply, resulting in a relatively high processing cost. Summary of the Invention

[0014] Further, a splash-proof plate is provided at the top end of the collection box.

[0015] The present invention provides a welding mechanism for a switching power supply through improvement. Compared with the prior art, it has the following improvements and advantages: Firstly, as the welding time of the welding end increases, the temperature on the surface of the welding end will become higher and higher. The heat generated by the excessive temperature will be transferred into the sealing cover. The expansion liquid in the sealing cover expands slowly when heated. The expansion liquid expanded in the sealing cover enters the temperature control tube through the connecting pipe. The expansion liquid entering the temperature control tube pushes the second piston and the lifting column upward. The lifting column drives the temperature control plate to slide upward on the ventilation box until the ventilation slot on the temperature control plate moves upward into the ventilation box. At this time, the ventilation box is in communication with the air storage cylinder. The gas in the air storage cylinder enters the heat dissipation nozzle through the first heat dissipation tube, the ventilation box and the second heat dissipation tube. The heat dissipation nozzle sprays the gas onto the surface of the welding end, realizing automatic heat dissipation of the welding end according to the temperature and ensuring that the welding work will not be affected.

[0016] Second: When the feeding conveyor belt of the present invention works, it conveys multiple welding frames to the feeding assembly in sequence. Then, the feeding assembly works to push the welding frames to the inside of the transfer assembly through the cross plate. Two L-shaped baffles assist in limiting the welding frames passing through the cross plate. While the feeding assembly is working, it also drives the air conveying assembly to work. The air conveying assembly works to pump the external gas into the air storage cylinder. The gas entering the air storage cylinder pushes the first piston to move closer to the first spring, and the first spring is compressed and deformed accordingly. Subsequently, the transfer assembly works to limit the welding frames therein. Then, the transfer assembly continues to work to drive the welding frames to rotate and pass through the welding assembly, slag cleaning assembly, and blanking assembly in sequence. When the welding frame passes through the welding assembly, the welding assembly works to automatically weld the switching power supply inside the welding frame. When the welding frame passes through the slag cleaning assembly, the slag cleaning assembly works to connect the air storage cylinder. The first spring releases its elastic force and pushes the first piston to slowly move away from the first spring. The first piston squeezes the gas in the air storage cylinder into the slag cleaning assembly, and the slag cleaning assembly sprays out the gas. The sprayed gas blows away the welding slag generated during the welding inside the welding frame. When the welding frame passes through the blanking assembly, the transfer assembly works to cancel the limit on the welding frame. Then, the blanking assembly works to suck and transfer the welding frame to the blanking conveyor belt for blanking. Finally, the blanking conveyor belt works to convey the welding frame, thereby realizing the automatic continuous feeding and welding of the switching power supply, with low processing costs and no need for personnel assistance to complete.

[0017] Third: During the process of the first lead screw slide table working to push the welding frame, it also drives the reciprocating frame to move horizontally back and forth. The reciprocating frame drives the third piston to slide back and forth in the air conveying cylinder by using the reciprocating rod. During the reciprocating sliding of the third piston, it first pumps the external gas into the air conveying cylinder through the air inlet pipe, and then squeezes the gas in the air conveying cylinder into the air storage cylinder through the air outlet pipe, achieving the purpose of supplying gas to the air storage cylinder and ensuring that there is gas in the air storage cylinder that can be provided to the heat dissipation assembly and the slag cleaning assembly.

The feeding conveyor belt 12 operates to sequentially convey the multiple welding frames to the feeding assembly 2. Then, the feeding assembly 2 operates to push the welding frames through the cross plate 15 into the transfer assembly 3. The two L-shaped baffles 16 assist in limiting the welding frames passing through the cross plate 15. While the feeding assembly 2 is operating, it also drives the air supply assembly 6 to operate. The air supply assembly 6 operates to pump the external gas into the air storage cylinder 13. The gas entering the air storage cylinder 13 pushes the first piston 17 to move closer to the first spring 18, and the first spring 18 is compressed and deformed accordingly. Subsequently, the transfer assembly 3 operates to limit the welding frames therein. Then, the transfer assembly 3 continues to operate to drive the welding frames to rotate and pass through the welding assembly 4, the slag cleaning assembly 7, and the blanking assembly 8 in sequence.

The expansion liquid expanded inside the sealing cover 51 enters the temperature control tube 55 through the connecting pipe 58. The expansion liquid entering the temperature control tube 55 then pushes the second piston 56 and the lifting column 57 to move upward. The lifting column 57 drives the temperature control plate 59 to slide upward on the ventilation box 54 until the air vent groove 594 on the temperature control plate 59 moves upward into the ventilation box 54.
