[0023] As shown in the figure, the fuse assembly machine disclosed in the present invention includes a sheet-insertion belt conveying mechanism, a sheet-insertion belt cutting mechanism, and a housing vibration plate 6. Specifically, the sheet-insertion belt conveying mechanism includes a sheet-insertion belt unwinding seat 1 and a pull-tab head 12. A card block 13 is provided in the pull-tab head 12. The card block 13 can be inserted into the gap on the sheet-insertion belt 2. The card block 13 is provided with a first inclined surface 15 at the contact end with the sheet-insertion belt 2. The pull-tab head 12 is connected to a first horizontal driving component. In this embodiment, the first horizontal driving component is a first linear cylinder 14. By controlling the first linear cylinder 14, the pull-tab head 12 can be driven to move back and forth. When the first linear cylinder 14 drives the pull-tab head 12 to move backward, the longest end of the clamping block 13 just presses the insert strip 2 and pushes the insert strip 2 to move backward to realize the backward conveyance of the insert strip 2. When the first linear cylinder 14 drives the pull-tab head 12 to move forward, since the clamping block 13 is provided with a first inclined surface 15, the clamping block 13 will not contact the insert strip 2 when moving back, so it will not drive the insert strip 2 forward. A shell conveyor 5 is provided at the discharge end of the shell vibration plate 6, and a moving block 10 is provided at the discharge end of the shell conveyor 5. The moving block 10 can be horizontally moved. The moving block 10 is connected to the piston rod of the second cylinder 8. The moving block 10 can be controlled to move horizontally by controlling the second cylinder 8. A feed port 23 and a discharge port 25 are provided on the moving block 10. The feed port 23 and the discharge port 25 are connected to the shell placement space 24 provided inside the moving block 10. The feed port 23 can be aligned with the discharge of the shell conveyor 5, and the discharge port 25 can be aligned with the discharge of the insert strip cutting mechanism. A shell pushing mechanism is provided on one side of the moving block 10. The insert strip cutting mechanism includes two support plates 11 provided on the left and right, and there is a gap 17 between the two support plates 11 for the insert strip to pass through. The gap 17 is a strip groove provided on one of the support plates 11, and a groove for the shell 7 to be pushed in is provided at the discharge of the rear end of the support plate 11. The two support plates 11 are provided with a first clearance groove and a second clearance groove. The first clearance groove is provided with a punching knife 18, and the second clearance groove is provided with a push block 19. The contact end of the push block 19 and the insert strip 2 is provided with a second inclined surface 20. Due to the existence of the second inclined surface 20, when the push block 19 is in motion, its second inclined surface 20 contacts the cut insert and exerts a force to push the insert out of the support plate 11. The moving block 10 is also provided with a push groove 21 connected to the housing placement space 24. The push groove 21 is aligned with the discharge port 25. A housing pusher 22 is movably provided in the push groove 21. The housing push mechanism includes a push cylinder 9. The piston rod of the push cylinder 9 can be aligned with the housing pusher 22.The outer shell conveying path 5 is provided with a lamp body conveying groove 26 which is connected with the lamp body conveying path 4. The lamp body conveying groove 26 is connected with the outer shell conveying groove 29 in the outer shell conveying path 5. A lamp body pushing member 27 is provided in the lamp body conveying groove 26. The lamp body pushing member 27 is connected with the pushing driving assembly. In this embodiment, the pushing driving assembly is a pushing cylinder 28. The lamp body is a light emitting diode. When working, the light emitting diode is vibrated and conveyed by the lamp body vibration disk 3 and is conveyed to the lamp body conveying groove 26 through the lamp body conveying path 4. At this time, the outer shell conveying path 5 is stacked with outer shells. The pushing cylinder 28 is actuated to drive the lamp body pushing member 27 to push the light emitting diode to the inside of the outer shell 7 in the outer shell conveying path 5, thereby realizing the installation operation of the fuse. After the plug is subsequently loaded, the light emitting diode contacts the plug and is connected to electricity through the two wiring ports at the rear of the outer shell 7. When in normal use, the light emitting diode does not emit light. When the plug is blown, the light emitting diode emits light to provide an alarm effect.

[0024] The insert strip 2 used in the processing of the present invention is a structure in which the insert bodies are connected together, and no additional traction section is provided, and the housing 7 is also an integral injection-molded structure.

[0025] It should also be noted that in this embodiment, cylinders are basically used as driving mechanisms to realize the movement of each component. In addition to using cylinders, common linear driving mechanisms such as linear motors, cams, screws, cylinders, transmission belts, etc. can also be used to realize the movement of each component.

[0026] The working principle of the present invention is as follows: the insert strip 2 is unwound on the unwinding seat 1, and the pull head 12 and the clamping block 13 cooperate to pull the insert strip 2 backward to realize the backward conveyance of the insert strip 2. At the same time, the shell 7 is conveyed outward from the shell vibration plate 6 and falls through the shell conveying path 5. At this time, the moving block 10 has moved to the bottom of the shell conveying path 5. At this time, the shell 7 passes through the feed port 23 on the moving block 10 and falls into the shell placement space 24. Then the moving block 10 moves again so that its discharge port 25 is aligned with the discharge position at the rear end of the two support plates 11. The outer shell pusher 22 on the moving block 10 is aligned with the piston rod of the pushing cylinder 9. The pushing cylinder 9 drives the outer shell pusher 22 to move, and pushes the outer shell 7 in the outer shell placement space 24 into the two support plates 11. At this time, the insert strip 2 in the support plate 11 is just inserted into the outer shell 7. Finally, the punching knife 18 is moved to punch and cut the insert strip 2 that has been inserted into the outer shell, and the pushing block 19 is moved, and its second inclined surface 20 cooperates with the cut insert strip to push the insert strip out from between the two support plates 11, so as to realize the discharge of the safety strip.

[0027] The structure of the present invention can realize the automatic conveying of the insert strip and the shell, and the insert strip and the shell are assembled in a manner that the shell is directly aligned with the insert strip and inserted. There is no need to set a traction section on the insert strip to pull the insert strip, which effectively saves materials and does not require the setting of a traction section punching component, making its structure and processing procedures simpler, effectively improving its processing efficiency and reducing the labor intensity of workers; in addition, the light sheet can be automatically installed into the shell during the assembly process, further improving its degree of automation.
