[0002] Fuses are also called current fuses. Fuses mainly play an overload protection role. If the fuse is correctly placed in the circuit, the fuse will melt and cut off the current when the current abnormally rises to a certain height and temperature, thereby protecting the safe operation of the circuit.

[0003] A tubular fuse is a type of fuse, which consists of a fuse tube and fuses at both ends of the fuse tube. When manufacturing a tubular fuse, the fuse and the fuse tube need to be connected together. The traditional method is that the staff uses a hot melt device to hot melt the two fuses and then connect them to the fuse tube. It is inconvenient to package both sides of the fuse tube at the same time, the packaging efficiency is low, and it is not convenient to clamp the fuse tube during packaging, and the packaging accuracy is low.

[0023] Initially, the staff places the fuse tube 4 into the placement slot of the placement rack 2 so that the fuse tube 4 is located between the two heating racks 10, and then fills the two storage hoppers 5 with fuses 6. Then the staff starts the telescopic rod of the hydraulic push rod 7 to extend. The telescopic rod of the hydraulic push rod 7 extends to push the lowest fuse 6 toward the direction close to the fuse tube 4. The lowest fuse 6 moves toward the direction close to the fuse tube 4 and contacts the heating rack 10. After one end of the lowest fuse 6 contacts the heating rack 10, the staff pauses the hydraulic push rod 7 and starts the heating rack 10. The two heating racks 10 heat one end of the two fuses 6 and both ends of the fuse tube 4. After heating for a period of time, the staff turns off the heating rack 10 and starts the electric slider 9 to move downward. The electric slider 9 moves downward. The two heating racks 10 are driven to move downward, and the two heating racks 10 move downward and break contact with the fuse 6. Then the staff continues to extend the telescopic rod of the hydraulic push rod 7, and the telescopic rod of the hydraulic push rod 7 continues to extend to push the lowest fuse 6 in the direction close to the fuse tube 4. The lowest fuse 6 continues to move in the direction close to the fuse tube 4 and contacts with the fuse tube 4. Through the above operation, both sides of the fuse tube 4 can be packaged at the same time to improve the packaging efficiency. The fuse 6 and the fuse tube 4 will be connected together after being in contact for a period of time.

The hexagonal prism 15 clamps the rotating shaft 11 and then clamps the clamping plate 12. After the fuse 4 is placed, the staff pulls the sliding frame 14 horizontally. The horizontal movement of the sliding frame 14 drives the hexagonal prism 15 to move horizontally. The hexagonal prism 15 moves horizontally and breaks away from the rotating shaft 11. The hexagonal prism 15 no longer clamps the rotating shaft 11, and then no longer clamps the clamping plate 12. The torsion spring 13 will rebound and drive the clamping plate 12 and the rotating shaft 11 to rotate. The clamping plate 12 rotates and connects with the fuse 4.
