[0017] 2. When facing a bottle cap fixed by pressing, the piston rod of the fourth electric push rod continues to descend to realize the assembly of the bottle cap and the perfume bottle. When facing a bottle cap fixed by spiral, the stepper motor drives the fourth electric push rod to rotate, and the annular belt also rotates in the support ring. During the rotation of the bottle cap, the fourth electric push rod continues to descend slowly to realize the assembly of the bottle cap and the perfume bottle. Caps of various shapes can be assembled on the same equipment. Compared with equipping each shape of cap with a separate equipment, the space occupied by the equipment in the production workshop can be greatly reduced. The effective use of space is very important for production enterprises, especially for enterprises with limited space. This can not only make the workshop layout more reasonable, but also free up more space for other production links. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Working principle: Step 1: The perfume bottle 44 is placed on the first conveyor belt 5 for conveyance, and is adjusted according to the shape of the bottle cap 45. When facing a round perfume bottle 44, the guide wheel 13 contacts the perfume bottle 44. Through the operation of the first electric push rod 7, the two groups of rectangular frames 6 are driven to move closer to each other, so as to achieve the contact between the guide wheel 13 and the perfume bottle 44, and ensure the moving guide effect of the perfume bottle 44. When facing a rectangular perfume bottle 44, the piston rod of the second electric push rod 10 pushes the rectangular cross plate 11 and the retractable plug plate 12 to move, and the retractable plug plate 12 extends out of the rectangular frame 6. After the retractable plug plate 12 extends out of the rectangular frame 6, the assembly plate 22 and the buffer plate 23 are installed on the retractable plug plate 12. The buffer plate 23 contacts the perfume bottle 44 to guide the rectangular perfume bottle 44. The perfume bottle 44 is conveyed on the first conveyor belt 5. When the perfume bottle 44 moves to the position of the elastic clamping plate 17, the piston rod of the third electric push rod 14 pushes the rectangular push plate 16 and the elastic clamping plate 17 to move. The two groups of rectangular push plates 16 and the elastic clamping plate 17 are close to each other to clamp and fix the perfume bottle 44. At the same time, the piston rod of the third electric push rod 14 also pushes the auxiliary push plate 18 to move. The auxiliary push plate 18 contacts the rotating limit plate 20. The auxiliary push plate 18 applies pressure to the rotating limit plate 20. The rotating limit plate 20 and the rotating rod 19 rotate to limit the subsequent perfume bottles 44 and prevent the subsequent perfume bottles 44 from continuing to move.

[0044] Step 2: The second conveyor belt 24 above drives the bottle cap 45 to move, the sixth electric push rod 38 pushes the guide side plate 39 to limit the bottle cap 45 to ensure the guiding effect during the movement of the bottle cap 45, the seventh electric push rod 40 pushes the retractable stop plate 41 to move, and the movement of the bottle cap 45 is blocked by the retractable stop plate 41 to assist the work of the assembly structure, the piston rod of the fourth electric push rod 27 pushes the annular belt 28 and the structure below the annular belt 28 to descend, and after the structure composed of the movable shaft 33, the clamping end 34, the pressure end 35 and the protective cap 36 descends to the moving height, the piston rod of the fifth electric push rod 29 rises, driving the telescopic rod 30 to rise, and when the telescopic rod 30 rises, it drives the limit ring 32 below to rise, thereby applying pressure to the pressure end 35 , the lower ends of the clamping ends 34 are brought close to each other, and the bottle cap 45 is fixed by the lower ends of the clamping ends 34 being brought close to each other, and the bottle cap 45 is driven to move to the top of the perfume bottle 44 by the movement of the crane 25 on the top mounting frame 4, and the bottle cap 45 is brought into contact with the perfume bottle 44 by the descending of the piston rod of the fourth electric push rod 27. When facing the bottle cap 45 fixed by pressing, the piston rod of the fourth electric push rod 27 continues to descend to realize the assembly of the bottle cap 45 and the perfume bottle 44. When facing the bottle cap 45 fixed by spiral, the stepping motor 26 drives the fourth electric push rod 27 to rotate, and the annular belt 28 also rotates in the supporting ring 43. During the rotation of the bottle cap 45, the fourth electric push rod 27 continues to descend slowly to realize the assembly of the bottle cap 45 and the perfume bottle 44.
