Finally, the piston suction head 52 movably installed on the upper side of the rotary positioning platform 2 sucks the forward piston B and installs it into the bottle body A.

[0081] In some embodiments, as Figure 2 As shown, the following steps are also included:

[0082] Step S04, assembling the bottom cover C; positioning the bottle body A through the rotary positioning platform 2 on the bottom cover assembly station, then loading the bottom cover C toward the dividing mechanism 61 through the bottom cover vibration plate 60 of the bottom cover assembly component 6, then the dividing mechanism 61 divides the bottom cover C onto the bottom cover conveyor belt 62, and finally, the bottom cover suction head 63 movably installed on the upper side of the rotary positioning platform 2 sucks the bottom cover C on the bottom cover conveyor belt 62 and assembles it onto the bottle body A.

[0083] In some embodiments, as Figure 2 As shown, the following steps are also included:

[0084] Step S05, assemble the decorative cover D; position the bottle body A by the rotatable indexing plate 70 on the decorative cover assembly station, and then convey the decorative cover D toward the indexing plate 70 by the decorative cover conveyor belt 71 of the decorative cover assembly component 7; in the process of conveying the decorative cover D by the decorative cover conveyor belt 71, the dispensing rod 72 installed on the decorative cover conveyor belt 71 can be lifted to dispense glue on the inner cavity of the decorative cover D, and then the reversing clamp 73 installed on the decorative cover conveyor belt 71 can be lifted to reverse the decorative cover D after dispensing glue; finally, the decorative cover clamp 74 movably installed between the decorative cover conveyor belt 71 and the indexing plate 70 clamps the decorative cover D on the decorative cover conveyor belt 71 and assembles it to the bottom cover C.

[0085] In some embodiments, as Figure 2 As shown, there are the following steps between step S03 and step S04:

[0086] In step S035, piston B is pushed to slide; the bottle A is positioned by the piston pushing the rotary positioning platform 2 on the workstation. Then, the first guide frame 81 which can be raised and lowered on the upper side of the rotary positioning platform 2 is lowered to align the bottle A. Then, the upper push rod 82 which can be raised and lowered relative to the first guide frame 81 passes through the first guide frame 81 and pushes the piston B to the bottom of the bottle A. Finally, the lower push rod 83 which can be raised and lowered on the bottom of the rotary positioning platform 2 passes through the rotary positioning platform 2 and pushes the piston B to the top of the bottle A.

[0087] In some embodiments, as Figure 2 As shown, the following steps are further included between step S04 and step S05:

[0088] Step S044, air tightness test; the bottle body A is positioned by the rotary positioning platform 2 on the air tightness test station, and then the pressure plate 91 installed on the upper side of the rotary positioning platform 2 can be raised and lowered to press down the bottom cover C, and then the telescopic air nozzle 92 installed on the bottom of the rotary positioning platform 2 can be raised and lowered to extend into the bottle body A to inflate it. After inflation, the pressure is maintained and the pressure change of the pressure sensor connected to the telescopic air nozzle 92 is detected; if the pressure of the pressure sensor increases, it is a leak; otherwise, it is not leaking.

[0089] In some embodiments, as Figure 3 As shown, step S03 specifically includes the following steps:

[0090] Step S031, piston B is loaded; the piston B is placed in the piston vibration plate 50, and the piston B in the piston vibration plate 50 is fed toward the reversing mechanism 51 through the piston conveying guide 53 connected between the piston vibration plate 50 and the reversing mechanism 51;

[0091] In step S032, the first material receiving plate 511 receives the material; the piston B in the piston conveying guide rail 53 first enters the connecting seat 515 connected to the piston conveying guide rail 53, and the material dividing rod 516 installed on the upper side of the connecting seat 515 rises, so that the piston B in the connecting seat 515 smoothly enters the first U-shaped groove 514 in the first material receiving plate 511; then the first material receiving plate 511 slides so that the multiple first U-shaped grooves 514 are connected to the connecting seat 515 one by one to receive the material. After all the first U-shaped grooves 514 have completed receiving the material, the material dividing rod 516 descends and is inserted into the piston B, thereby limiting the piston B in the connecting seat 515 from continuing to feed the material toward the first material receiving plate 511;

[0092] Step S033, detect the forward and reverse direction of piston B; the height sensor 512 located on the side of the first material receiving plate 511 detects the height of piston B, and determines the forward and reverse direction of piston B by the size of the height; if the height of piston B is the first height, piston B is in the forward direction, and the reversing cylinder 513 located on the side of the first material receiving plate 511 clamps the current piston B and places it on the piston distribution guide rail 54 between the reversing mechanism 51 and the piston suction head 52; if the height of piston B is the second height, piston B is in the reverse direction, and the reversing cylinder 513 clamps the current piston B, rotates it 180 degrees, and then places it on the piston distribution guide rail 54; wherein the first height is greater than the second height.

[0093] Step S034, piston assembly B; the piston B in the piston material distribution guide 54 enters the second U-shaped groove 551 of the second material receiving plate 55, and then the second guide frame 57 installed on the upper side of the rotary positioning platform 2 is lowered to guide the bottle body A, and then the piston suction head 52 sucks the piston B in the second U-shaped groove 551 and assembles it into the inside of the bottle body A.

[0096] Step S042: The material distributing mechanism 61 distributes the materials. The bottom caps C in the bottom cap conveying guide rail 64 first enter the third U-shaped groove 612 of the third material receiving plate 611. The third material receiving plate 611 slides so that the multiple third U-shaped grooves 612 are connected to the bottom cap conveying guide rail 64 one by one to receive the materials. After all the third U-shaped grooves 612 have received the materials, the material transfer suction head 613 movably installed between the third material receiving plate 611 and the bottom cap conveying belt 62 sucks the bottom caps C in the third U-shaped grooves 612 and transfers them to the bottom cap conveying belt 62.

[0097] Step S043, assembling the bottom cap C; the bottom cap conveyor belt 62 conveys the bottom cap C toward the bottom cap suction head 63, and then the first guide clamp 66 installed on the upper side of the rotary positioning platform 2 is lowered and clamps the bottle body A. Finally, the bottom cap suction head 63 clamps the bottom cap C on the bottom cap conveyor belt 62 and assembles it onto the bottle body A.

[0098] In some embodiments, as Figure 5 As shown, step S05 specifically includes the following steps:

[0099] Step S051, loading the decorative cover D; loading the decorative cover D onto the decorative cover conveyor belt 71 by means of a robot, placing the decorative cover D upside down on the decorative cover conveyor belt 71, and the decorative cover conveyor belt 71 conveys the decorative cover D toward the indexing plate 70;

[0100] Step S052, dispensing glue; in the process of the decorative cover conveyor belt 71 conveying the decorative cover D, the dispensing stick 72 descends and dispenses glue in the inner cavity of the indexing plate 70;

[0101] Step S053, photo inspection and reversing: The inspection camera 75, which is movably mounted between the dispensing rod 72 and the reversing clamp 73, takes a photo inspection of the glue dispensing quality of the decorative cover D. If the inspection passes, the reversing clamp 73 picks up the qualified decorative cover D, rotates it 180 degrees, and then reverses it, and places it on the decorative cover conveyor belt 71. If the inspection fails, the reversing clamp 73 does not move, and the unqualified decorative cover D is driven by the decorative cover conveyor belt 71 into the waste hopper.

[0102] Step S054, assembling the decorative cover D; the second guide clamp 77 slidably mounted on the upper side of the indexing plate 70 extends and clamps the bottle body A, and then the decorative cover clamp 74 clamps the decorative cover D after the reversal on the decorative cover conveyor belt 71 and assembles it to the bottom cover C of the bottle body A.

[0103] Step S055, pressing; by lifting and lowering the pressing head 781 mounted on the upper side of the indexing plate 70, the decorative cover D is pressed down so that the decorative cover D and the bottom cover C are firmly attached;

[0106] See Figures 6 to 30 The present invention also provides a fully automated assembly device for a cosmetic vacuum bottle. The automated assembly method for the cosmetic vacuum bottle is implemented based on the fully automated assembly device for the cosmetic vacuum bottle. The fully automated assembly device includes a workbench 1, a bottle feeding conveyor belt 3, an oiling component 4, and a piston assembly component 5.

[0107] See Figure 6 、 Figure 7 and Figure 30 The workbench 1 is linearly spaced apart with a bottle feeding station, an oiling station, and a piston assembly station. Both the oiling station and the piston assembly station are equipped with a rotary positioning platform 2, which is used to position the bottle A. A bottle feeding conveyor belt 3 is installed at the bottle feeding station and connected to the workbench 1. Multiple bottle positioning seats are linearly spaced apart on the bottle feeding conveyor belt 3. Each of these positioning seats has a bottle positioning hole. During feeding, the bottle A is placed in the positioning hole. This fully automated assembly equipment is primarily suitable for bottles with openings at both ends. In this case, the bottle A is placed upside down in the bottle positioning seat, with the lower opening of the bottle A facing upward, to facilitate subsequent oiling and piston assembly. For bottles with only an upper opening, the bottle is placed upright in the bottle positioning seat, with its upper opening facing upward. The oiling assembly 4 is installed at the oiling station. The oiling assembly 4 includes an oil spray rod 40 that can be extended into the bottle body A to rotate and spray oil. At this station, oiling is carried out in the bottle body A, which facilitates the installation of the piston and makes the piston movement smoother.

[0108] See Figures 6 to 9 The piston assembly component 5 is installed at the piston assembly station and is used to assemble the piston B into the bottle body A. The piston assembly component 5 includes a piston vibration plate 50 for loading the piston B, a reversing mechanism 51 for detecting the forward and reverse direction of the piston B and reversing the reverse piston B, and a piston suction head 52 movably mounted on the upper side of the rotary positioning platform 2. The piston suction head 52 is used to suck the forward piston B and install it into the bottle body A. The reversing mechanism 51 detects the forward and reverse direction of the piston B. If the detection is forward, no reversal is required. If the detection is reverse, the reversing mechanism 51 rotates it 180 degrees to reverse the direction, ensuring that each piston is installed in the forward direction and ensuring assembly quality.

[0109] like Figure 6 、 Figure 7 、 Figure 18 、 Figure 19 and Figure 22 As shown, a bottom cap assembly station is located behind the piston assembly station. A rotary positioning platform 2 and a bottom cap assembly assembly 6 are installed at this station. The rotary positioning platform 2 is used to position the bottle body A, and the bottom cap assembly 6 is used to assemble the bottom cap C onto the bottle body A. The bottom cap assembly 6 includes a bottom cap vibrating plate 60 for loading the bottom caps C, a material distribution mechanism 61, a bottom cap conveyor belt 62, and a bottom cap suction head 63 movably mounted on the upper side of the rotary positioning platform 2. The material distribution mechanism 61 is used to distribute the bottom caps C onto the bottom cap conveyor belt 62. The bottom cap suction head 63 is used to absorb the bottom caps C from the bottom cap conveyor belt 62 and assemble them onto the bottle body A. The material distribution mechanism 61 enables the simultaneous assembly of multiple bottom caps C, effectively improving assembly efficiency. Furthermore, a plurality of bottle positioning seats are arranged linearly on the bottom cap conveyor belt 62. These bottle positioning seats are used to position the bottles A, preventing them from shifting during the movement of the bottom cap conveyor belt 62 and ensuring precise positioning.

[0110] like Figure 6 、 Figure 7 、 Figure 25 and Figure 26 As shown, a decorative cover assembly station is located behind the base cover assembly station. A decorative cover assembly assembly 7 is installed at this station. This assembly is used to assemble decorative covers D onto base covers C. Decorative cover assembly 7 includes a rotating indexing plate 70 mounted behind the workbench 1, a decorative cover conveyor belt 71 for loading decorative covers D onto the indexing plate 70, a dispensing rod 72 and a reversing clamp 73 movably mounted on the decorative cover conveyor belt 71, and a decorative cover clamp 74 movably mounted between the indexing plate 70 and the decorative cover conveyor belt 71. Multiple bottle positioning seats are circumferentially spaced evenly on the indexing plate 70, which are used to position bottles A. A robotic arm is used to load decorative covers D onto the decorative cover conveyor belt 71. Decorative covers D are inverted on the decorative cover conveyor belt 71, with their openings facing upward, to facilitate dispensing by the dispensing rod 72. A plurality of decorative cover positioning seats are arranged linearly and spaced apart on the decorative cover conveyor belt 71. The decorative cover D is placed within these seats to prevent displacement. A dispensing stick 72 is used to dispense glue into the inner cavity of the decorative cover D. A reversing clamp 73 is used to reverse the direction of the decorative cover D after the glue is applied. That is, the reversing clamp 73 grasps the decorative cover D and rotates it 180 degrees so that its opening faces downward, facilitating the installation of the decorative cover D onto the bottom cover C. The decorative cover clamp 74 is used to pick up the decorative cover D from the decorative cover conveyor belt 71 and assemble it onto the bottom cover C.

[0111] like Figure 6 、 Figure 7 、 Figure 9 、 Figure 16 and Figure 17 As shown, a piston pushing station is provided between the piston assembly station and the bottom cover assembly station. A rotary positioning platform 2 and a piston pushing assembly 8 are installed at the piston pushing station. The rotary positioning platform 2 is used to position the bottle body A, and the piston pushing assembly 8 is used to push the piston within the bottle body, simulating the actual movement of the piston. The inner wall of the bottle body is coated with lubricating oil, which also facilitates lubrication when pushing the piston. The piston pushing assembly 8 includes a first guide frame 81 that is liftably mounted on the upper side of the rotary positioning platform 2, an upper push rod 82 that is liftably mounted on the upper side of the first guide frame 81, and a lower push rod 83 that is liftably mounted on the bottom of the rotary positioning platform 2. The first guide frame 81 is used to guide the bottle body A when pushing the piston B. The first guide frame 81 is provided with a guide hole that matches the outer contour of the bottle body A. When the first guide frame 81 is lowered, the bottle body A is placed in the guide hole, thereby supporting the bottle body A and preventing it from tilting. The upper push rod 82 passes through the first guide frame 81 and pushes the piston B downward, while the lower push rod 83 passes through the rotary positioning platform 2 and pushes the piston B upward. This structure is mainly suitable for bottles with openings at both ends. If the bottle has only an upper opening, the lower push rod is not used; the upper push rod only needs to push the piston downward.

[0112] like Figure 6 、 Figure 7 、 Figure 19 and Figure 24 As shown, an airtightness testing station is provided between the bottom cover assembly station and the decorative cover assembly station. A rotary positioning platform 2 and an airtightness testing assembly 9 are installed at the airtightness testing station. The rotary positioning platform 2 is used to position the bottle body A, and the airtightness testing assembly 9 is used to perform an airtightness test on the bottle body A after the bottom cover C is assembled. The airtightness testing assembly 9 includes a pressure plate 91 that can be raised and lowered on the upper side of the rotary positioning platform 2, and a telescopic air nozzle 92 that can be raised and lowered on the bottom of the rotary positioning platform 2. The pressure plate 91 is used to press down the bottom cover C, and the telescopic air nozzle 92 is used to extend into the interior of the bottle body A to inflate it. The telescopic air nozzle is connected to an air pipe, on which a pressure sensor is installed. During the airtightness test, the pressure plate presses down the bottom cover, and then the telescopic air nozzle rises and extends into the interior of the bottle body to inflate it. After inflation, the pressure is maintained, and the pressure change on the pressure sensor is detected. If the pressure does not change, there is no air leakage; otherwise, there is an air leakage. This structure can automatically complete the air tightness inspection with a high degree of automation. Through the air tightness inspection, the assembly quality can be guaranteed and the assembly effect is good.

[0113] like Figures 8 to 15As shown, one side of the reversing mechanism 51 is connected to the piston vibrating plate 50 via a piston conveying guide 53, while the other side of the reversing mechanism 51 feeds material toward the piston suction head 52 via a piston material distribution guide 54. The reversing mechanism 51 includes a first material receiving plate 511 slidably mounted on the end of the piston conveying guide 53, at least one height sensor 512 mounted on one side of the first material receiving plate 511, and reversing cylinders 513 symmetrically mounted on both sides of the first material receiving plate 511. First U-shaped grooves 514 are provided on both sides of the first material receiving plate 511, and the first material receiving plate 511 can be slid to connect any of the first U-shaped grooves 514 with the piston conveying guide 53. There are two height sensors 512, each corresponding to the two first U-shaped grooves 514. Using two first U-shaped grooves allows for simultaneous detection and reversing of the process on both sides, improving efficiency. Height sensor 512 faces first U-shaped groove 514 and is used to detect the forward and reverse direction of piston B. The height sensor can also detect the height of the piston. Reversing cylinder 513 is used to reverse the direction of piston B. When the piston's center column is facing upward, it is at a greater height, indicating the piston is in the forward direction. The reversing cylinder simply clamps the piston and places it on the piston distribution guide rail without reversing its direction. When the center column is facing downward, it is at a lower height, indicating the piston is in the reverse direction. The reversing cylinder clamps the piston, rotates it 180 degrees, reverses its direction, and then places it on the piston distribution guide rail.

[0114] A connecting seat 515 is installed between the first material receiving plate 511 and the piston conveying guide rail 53. A material dividing rod 516 is installed on the upper side of the connecting seat 515 in a liftable manner. The material dividing rod 516 can be inserted into the center hole b1 of the piston B; when the material dividing rod is inserted into the piston, it can be limited on the connecting seat, thereby limiting the piston in the piston conveying guide rail from continuing to feed toward the first material receiving plate, thereby controlling the assembly rhythm.

[0115] A second material receiving plate 55 is fixed to the end of the piston material distribution guide 54, and a plurality of second U-shaped grooves 551 are arranged on the second material distribution plate 55 at intervals along the straight line direction. The second U-shaped grooves are used to receive the piston on the piston material distribution guide. The end of the piston material distribution guide close to the reversing mechanism can be tilted or the piston material distribution guide as a whole can be tilted to facilitate the sliding of the piston along the piston material distribution guide and smooth movement. First support blocks 56 are symmetrically mounted on either side of the second receiving plate 55. A first horizontal slide 561 is horizontally slidably mounted on the first support block 56. The piston suction head 52 is arbitrarily mounted on the first horizontal slide 561, which drives the piston suction head 52 between the second receiving plate and the rotary positioning platform. A second guide frame 57 is arbitrarily mounted on the first support block 56. This second guide frame 57 is used to align the bottle A during assembly of the piston B. The second guide frame 57 is provided with a guide hole that matches the outer contour of the bottle A. When the second guide frame 57 is lowered, the bottle A is positioned within the guide hole, thereby supporting the bottle A and preventing it from tilting. The piston suction head 52 can pass through the second guide frame 57. During piston assembly, the second guide frame 57 is lowered to support the bottle A, and then the piston suction head 52 absorbs the piston from the second U-shaped groove 551 and assembles it into the bottle A.

By sliding the third material receiving plate 611, any third U-shaped groove 612 can be connected to the bottom cover conveying guide rail 64 for material receiving, and a material transferring suction head 613 is movably installed on the upper side of the third material receiving plate 611, and the material transferring suction head 613 is used to transfer the bottom cover C in the third U-shaped groove 612 to the bottom cover conveyor belt 62.

[0117] like Figure 22 and Figure 23 As shown, a second support 65 is mounted on the end of the bottom cap conveyor belt 62 away from the dispensing mechanism 61. A second horizontal slide 651 is slidably mounted on this second support 65. A bottom cap suction head 63 is slidably mounted on this second horizontal slide 651. The second horizontal slide 651 drives the bottom cap suction head 63 to slide between the end of the bottom cap conveyor belt and the rotary positioning platform, facilitating suction and assembly of the bottom caps by the suction head. A first guide jaw 66 is slidably mounted on the second support 65. The first guide jaw 66 is used to clamp the bottle body A during assembly of the bottom cap C, preventing the bottle body A from tilting and ensuring assembly quality.

[0118] like Figures 25 to 29As shown, a detection camera 75 is installed on the decorative cover conveyor belt 71. The detection camera 75 is located between the dispensing stick 72 and the reversing clamp 73. The detection camera 75 is used to take photos to detect the dispensing effect. The additional detection camera takes photos of the decorative cover after dispensing. If the dispensing is unqualified, the reversing clamp does not work, and the unqualified decorative cover is driven by the decorative cover conveyor belt into the waste hopper at the end. If the dispensing is qualified, the reversing clamp reverses its direction, and the decorative cover clamp 74 grasps the reversing decorative cover and assembles it on the bottle body. This can effectively ensure the dispensing effect and thus ensure the assembly quality, avoiding loose adhesion due to insufficient glue. The detection camera is prior art and will not be described in detail in this embodiment.

[0119] A third support seat 76 is installed between the dividing plate 70 and the decorative cover conveyor belt 71. A third horizontal slide 761 is slidably installed on the third support seat 76.

[0121] like Figure 30 As shown, the oiling assembly 4 also includes a lift slide 41 that is liftably mounted on the upper side of the rotary positioning platform 2. The oil spray rod 40 is mounted on the lift slide 41. The oil spray rod 40 includes a rotating base 401 that can rotate relative to the lift slide 41. The rotating base 401 is mounted with two adjustable oil spray plates 402, each of which is provided with an oil spray nozzle 403. The use of two adjustable oil spray plates 402 allows the spacing to be adjusted according to the size of the bottle mouth, thus adapting to a wider range of applications. The use of a rotating and liftable oil spraying method ensures uniform oil spraying and good oil spraying effect.
