The one-way bearing 33 has the characteristic of one-way transmission. When the rotating sleeve 32 rotates clockwise, the one-way bearing 33 will idle, and will not drive the hollow rotating column 23 to rotate. When the rotating sleeve 32 rotates counterclockwise, the one-way bearing 33 will drive the hollow rotating column 23 to rotate counterclockwise. A guide protrusion 35 is fixed on the inner wall of the rotating sleeve 32. The interior of the rotating sleeve 32 is inserted with a plug column 24. The plug column 24 The cam 35 is provided with a guide slot 34 on the side wall, and the guide protrusion 35 is located inside the guide slot 34.

The four limit slots 31 are arranged at equal intervals along the circumference of the side wall of the hollow rotating column 23. The limit block 49 is snapped into the limit slot 31 to limit the hollow rotating column 23, thereby ensuring the stability of the hollow rotating column 23, and thus ensuring the stability of the turntable 14 when it is not driven to rotate;

[0050] The test ejection mechanism is connected to the fixing frame 12. The test ejection mechanism is used to test the tightness of the assembly of the fuse 57 and the fuse holder 56, and to eject the fuse 57 from the fuse holder 56. The test ejection mechanism includes a mounting plate 25 fixedly connected to the lower end of the fixing frame 12. The upper end of the mounting plate 25 is mounted with a third electric push rod 26. The telescopic end of the third electric push rod 26 is fixed with a sleeve rod 27. The interior of the sleeve rod 27 is mounted with a fourth electric push rod 39. The telescopic end of the fourth electric push rod 39 is fixed with a sleeve rod 27. An ejector rod 36 is fixed to the end, and the ejector rod 36 extends out of the sleeve rod 27. A sleeve 28 is sleeved on the ejector rod 36, and a first spring 37 is sleeved on the ejector rod 36. One end of the first spring 37 is connected to the sleeve 28, and the other end of the first spring 37 is connected to the sleeve rod 27.

At this time, the first spring 37 is in a compressed state, and the first spring 37 is used to apply a thrust to the sleeve 28, and the sleeve 29 is used to apply a thrust to the fuse 57, which can test the assembly tightness of the fuse 57 and the fuse holder 56. The elastic force of the first spring 37 can be preset. When the assembly tightness of the fuse 57 and the fuse holder 56 is not enough, that is, when the elastic force of the first spring 37 exceeds the friction between the assembly of the fuse 57 and the fuse holder 56, the first spring 37 will push the sleeve 28 to move, and then the fuse 57 will be opened. 7 can be pushed by the sleeve 28, and when the sleeve 28 moves, it can drive the extrusion block 38 to contact the second pressure touch switch 30, and the second pressure touch switch 30 can activate the four electric push rods 39 to extend, driving the ejection rod 36 to move, so as to eject the fuse 57 from the fuse holder 56 and allow the ejected fuse 57 to enter the leakage chute 46 for discharge. On the contrary, when the fuse 57 and the fuse holder 56 are assembled tightly enough, that is, the elastic force of the first spring 37 does not exceed the friction force between the assembly of the fuse 57 and the fuse holder 56, the first spring 37 will not push the sleeve 28 to move, and the sleeve 28 will not move and will not push the fuse 57, thereby not affecting the assembly between the fuse 57 and the fuse holder 56;

The top of the unloading push block 41 has an inclined surface. The unloading push block 41 is located inside the unloading port 44. Since the unloading push block 41 has an inclined surface, when the unloading push block 41 pushes the fuse holder 56 upward, the fuse holder 56 will slide along the inclined surface of the unloading push block 41 to the first unloading chute 45 and the second unloading chute 47;

[0053] A fuse assembly mechanism is disposed within the fuse placement slot 43 and is used to assemble a fuse 57 into the fuse holder 56.

The fuse holder 56 can be placed in the fuse holder placement slot 51 on the right side in advance.

[0060] The second electric push rod 9 is started to extend, driving the movable plate 8 to move downward, which in turn can drive the first pressing plate 18 and the second pressing plate 20 to move downward. The fuse holder 56 can be pressed by the first pressing plate 18, and the fuse holder 56 is positioned and fixed on all sides by the first positioning rod 19. Then, when the slider 7 contacts the first pressure touch switch 5 and triggers the first pressure touch switch 5, the first electric push rod 3 can be started to extend, driving the loading rod 54 to push the fuse 57 into the fuse holder 56, so that the fuse 57 can be efficiently assembled into the fuse holder 56.

[0061] Then the second electric push rod 9 is started to retract, so that the slider 7 leaves the first pressure touch switch 5, and the first electric push rod 3 will retract, driving the loading rod 54 to reset and move to the inner side of the fuse placement groove 43, and driving the first pressure plate 18 and the first positioning rod 19 to leave the fuse holder 56, and then the guide groove 34 uses the guiding and limiting effect of the guide protrusion 35 to drive the rotating sleeve 32 to rotate ninety degrees counterclockwise, and drive the hollow rotating column 23 to rotate ninety degrees counterclockwise through the one-way bearing 33, and then drive the turntable 14 to rotate ninety degrees counterclockwise through the hollow rotating column 23, and move the new fuse holder 56 to the bottom of the first pressure plate 18, and move the assembled fuse holder 56 and fuse 57 to one side of the test ejection mechanism;

[0062] Then the second electric push rod 9 is started to extend, driving the moving plate 8 to move downward, and the assembly of the fuse holder 56 and the fuse 57 is continued. At the same time, the moving plate 8 moves downward, driving the second pressing plate 20 to press down on the fuse holder 56, and the conductive contact 22 contacts the electrode sheet of the fuse holder 56 for electrical conduction, which can test whether the conductivity of the fuse 57 and the fuse holder 56 after assembly is qualified. Then the third electric push rod 26 is started to extend, driving the sleeve rod 27 and the sleeve 28 to move, passing through the top outlet 53 and the fuse holder 56 through the sleeve 28, and resisting the fuse 57 inside the fuse holder 56 through the sleeve 28. At this time, the first spring 37 is in a compressed state, and the first spring 37 is used to apply a thrust to the sleeve 28, and a thrust is applied to the fuse 57 through the sleeve 29, which can be The assembly tightness of the fuse 57 and the fuse holder 56 is tested. When the conductivity test after the fuse 57 and the fuse holder 56 are assembled is unqualified or when the tightness test after the fuse 57 and the fuse holder 56 are assembled is unqualified, the fourth electric push rod 39 is started to extend, driving the ejection rod 36 to move, for ejecting the fuse 57 from the fuse holder 56, and allowing the ejected fuse 57 to enter the leakage chute 46 for discharge.
