[0027] like Figures 1 to 12 As shown, in this embodiment, the present invention includes a base 1, a plurality of essential oil bottles 16, a plurality of drawer cartons 15, a bottle feeding conveyor line 11, an NG line 12, a box feeding conveyor line 14, and a box discharging conveyor line 17. A bottle turntable 3 and a box turntable 4 are arranged side-by-side on the upper end of the base 1. A plurality of snap-fit ​​devices 5, adapted to the essential oil bottles, are evenly distributed around the circumference of the bottle turntable 3. A plurality of box fixtures 6, adapted to the drawer cartons, are evenly distributed around the circumference of the box turntable 4. The tangent point between the bottle turntable 3 and the box turntable 4 is the boxing station. A detection module is arranged beside the bottle turntable 3. The testing module includes several rotating modules 120 for driving the essential oil bottle to rotate along the axis. One end of the bottle feeding conveyor line 11 is provided with a pressing feeding module 2 corresponding to the buckling device 5. Above the bottle turntable 3, an NG discharge module 9 corresponding to the NG line 12 and a box assembly module 100 corresponding to the boxing station are fixedly provided. One end of the box feeding conveyor line 14 is provided with a box feeding module 110 corresponding to the box fixture 6. The side of the box turntable 4 is provided with an inner box opening mechanism 7 and a pressing and flipping module 8 corresponding to the box discharge conveyor line 17.

[0028] As can be seen from the above scheme, the bottle feeding conveyor line 11 is used to convey a number of essential oil bottles 16 that have been packaged and marked with production dates, and the box feeding conveyor line 14 is used to convey a number of drawer cartons 15 to be boxed. Stepper motors are installed at the bottom of both the bottle turntable 3 and the box turntable 4. As the stepper motors drive the bottle turntable 3 and the box turntable 4 to rotate in opposite directions, the pressing feeding module 2 pushes the number of essential oil bottles 16 into the number of latching devices 5 on the bottle turntable 3. The latching devices 5 pre-tighten the essential oil bottles 16 to ensure their stability. The box feeding module 110 pushes the number of drawer cartons 15 into the number of box fixtures 6. The box fixtures 6 are used to support and position the inner and outer boxes of the drawer cartons 15. The inner box opening mechanism 7 is used to push the drawer cartons 15 that have entered the box fixtures 6 downwards. This allows the inner and outer boxes of the drawer box 15 to be in a semi-separated state. Several rotating modules 120 are used to adjust the rotation angle and detection position of the essential oil bottle 16, and the detection module sequentially detects the detection position of the essential oil bottle. Products that fail the test are pushed into the NG line 12 by the NG discharge module 9. The NG line 12 is used to collect unqualified products. When qualified products enter the boxing station, the boxing assembly module 100 pushes the qualified essential oil bottle 16 into the inner box of the drawer box 15. The unloaded buckling device 5 returns to the starting point and is reloaded as the bottle turntable 3 rotates. The drawer box 15 containing the essential oil bottle 16 enters the unloading station as the box turntable 4 rotates. The pressing and flipping module 8 is used to pull out the drawer box 15 and press the inner and outer boxes together, and push it out to the box discharge conveyor line 17 to be transported to the next station for boxing. Therefore, compared with the prior art, the present invention greatly improves the efficiency of product transfer and boxing through the structural layout of the bottle turntable 3 and the box turntable 4. Furthermore, through the structural design of the buckle device 5 and the box fixture 6, it meets the needs of large-scale production, reduces the burden of manual operation, realizes automated docking and boxing, meets the production needs of automated production lines in factories, and through the detection module, it sequentially detects various parts of the essential oil bottle, which not only reduces the difficulty of manual detection and improves detection efficiency, but also ensures the accuracy and quality of product detection.

[0029] like Figure 2As shown, in this embodiment, the plurality of the latching devices 5 include a rectangular base 51, two pre-tightening claws 54 and two spring plungers. The rectangular base 51 is provided with fixing blocks 52 at both ends. The inner sides of the two fixing blocks 52 are provided with bottleneck limiting arc surfaces 53 adapted to the size of the essential oil bottle 16. An inlet end 531 and an outlet end 532 are formed between the inner sides of the two fixing blocks 52. The width of the inlet end 531 is greater than the width of the outlet end 532. A horizontal rotating platform 55 is provided on the base 51 between the two fixing blocks 52. Each of the two fixing blocks 52 is provided with a flat groove 57 adapted to the pre-tightening claws 54. The pre-tightening claws 54 are all set in the flat grooves 57 through a rotating shaft 56. The outer sides of the two pre-tightening claws 54 are movably connected to the two spring plungers respectively.

The outer box push cylinder 140 is used to cooperate with the material pulling cylinder 87 to push the drawer cardboard box 15 after the bottle is filled in the box fixture 6 to the U-shaped positioning box 89.

[0046] As can be seen from the above scheme, the outer box pressing cylinder 84 is vertically arranged at the end of the adjustable block 83. The outer box pressing cylinder 84 is used to drive the rectangular pressing block 85 to press the outer box of the drawer cardboard box 15 downwards and press it against the inner box, so that the inner and outer boxes of the drawer cardboard box 15 are combined. The material pulling cylinder 87 is used to drive the push plate 88 to move linearly back and forth, so that the push plate 88 pushes the combined drawer cardboard box 15 onto the U-shaped positioning box 89. The previous drawer cardboard box 15 The paper box 15 is squeezed out by the next drawer box 15. The adjusting column 90 is used to adjust the distance between the U-shaped positioning box 89 and the transfer plate 86. Due to the height difference between the U-shaped positioning box 89 and the transfer plate 86, the squeezed-out drawer box 15 falls down in the extrusion direction due to inertia. The baffle plate 97 is used to block the drawer box 15 that is about to be squeezed out. The discharge cylinder 95 drives the second box pusher 96 to push the fallen drawer box 15 to the box discharge conveyor line 17.

[0047] In this embodiment, the workflow of the present invention is as follows:

[0048] The bottle feeding conveyor 11 transports several essential oil bottles 16 to the bottle loading station, and the box feeding conveyor 14 transports several drawer cartons 15 to the box loading station. As the stepper motor drives the bottle turntable 3 and the box turntable 4 to rotate in opposite directions, the pressing feeding module 2 pushes several essential oil bottles 16 into several latching devices 5 on the bottle turntable 3, and the box feeding module 110 pushes several drawer cartons 15 into several box fixtures 6. The inner box opening mechanism 7 pushes the drawer cartons 15 into the box fixtures 6 downwards, so that the inner and outer boxes of the drawer cartons 15 are in a semi-separated state. The rotating module 120 adjusts the rotation of the essential oil bottles 16. The angle and detection points are checked sequentially by the detection module. Products that fail the inspection are pushed into the NG line 12 by the NG discharge module 9. When qualified products enter the boxing station, the boxing assembly module 100 pushes the qualified essential oil bottle 16 into the inner box of the drawer carton 15. The unloaded buckle device 5 returns to the bottle loading station for reloading as the bottle turntable 3 rotates. The drawer carton 15 containing the essential oil bottle 16 enters the box unloading station as the box turntable 4 rotates. The pressing and flipping module 8 pulls out the drawer carton 15 and presses the inner and outer boxes together, and pushes it to the box discharge conveyor line 17 for conveying to the next station for boxing.

[0049] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
