Description

Technical Field

[0001] This invention relates to the field of cosmetic vacuum bottle assembly, and in particular to an automated assembly method for cosmetic vacuum bottles. Background Technology

[0002] For women, makeup has become an essential part of daily life, and vacuum-sealed cosmetic bottles are commonly used packaging containers for cosmetics. (See also...) Figure 1 Vacuum cosmetic packaging bottles generally include a bottle body with an upper opening and a lower opening at the top and bottom ends, respectively. The outer diameter of the upper opening is smaller than that of the lower opening. A piston is slidably installed inside the bottle body. A bottom cap is fitted at the lower opening, and a decorative cap is fitted on the outside of the bottom cap.

[0003] Currently, cosmetic packaging bottles are mainly assembled manually. During assembly, oil is first applied to the inner wall of the bottle, then the piston is installed, followed by the bottom cap, and finally the decorative cap. This process is labor-intensive, the processes are not continuous, the material turnover time is long, and the assembly efficiency is low. Moreover, the inspection process is all done manually, so the assembly quality cannot be guaranteed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The problem to be solved by the present invention is to provide an automated assembly method for cosmetic vacuum bottles, so as to overcome the shortcomings of low assembly efficiency and poor assembly quality of existing cosmetic vacuum bottle assembly methods.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, the present invention provides an automated assembly method for cosmetic vacuum bottles, comprising the following steps:

[0008] Step S01, bottle loading; depending on the type of bottle, the bottle is placed upside down or upright in the bottle positioning seat of the bottle loading conveyor belt, and then fed towards the workbench via the bottle loading conveyor belt.

[0009] Step S02, oiling the bottle: The bottle is positioned by a rotating positioning table on the oiling station, and then the oil spraying rod of the oiling component is inserted into the bottle for rotating oil spraying.

[0010] Step S03: Assemble the piston; Position the bottle body using the rotary positioning table on the piston assembly station, then feed the piston towards the reversing mechanism via the piston vibrating plate of the piston assembly assembly, then the reversing mechanism detects the forward and reverse direction of the piston and reverses the reverse piston, and finally the piston suction head movably mounted on the upper side of the rotary positioning table picks up the forward piston and inserts it into the bottle body.

[0011] In some embodiments, the following steps are also included:

[0012] Step S04: Assemble the bottom cap; Position the bottle body using the rotary positioning table on the bottom cap assembly station, then feed the bottom cap towards the material distribution mechanism via the bottom cap vibrating plate of the bottom cap assembly assembly assembly, then the material distribution mechanism distributes the bottom cap onto the bottom cap conveyor belt, and finally the bottom cap suction head movably mounted on the upper side of the rotary positioning table picks up the bottom cap on the bottom cap conveyor belt and assembles it onto the bottle body.

[0013] In some embodiments, the following steps are also included:

[0014] Step S05: Assemble the decorative cap; the bottle body is positioned by a rotatable indexing plate at the decorative cap assembly station, and then the decorative cap is conveyed toward the indexing plate by the decorative cap conveyor belt of the decorative cap assembly assembly assembly; during the conveying of the decorative cap by the decorative cap conveyor belt, a dispensing rod that can be raised and lowered on the decorative cap conveyor belt dispenses glue to the inner cavity of the decorative cap, and then a reversing gripper that can be raised and lowered on the decorative cap conveyor belt reverses the direction of the glued decorative cap; finally, the decorative cap gripper that is movably installed between the decorative cap conveyor belt and the indexing plate picks up the decorative cap on the decorative cap conveyor belt and assembles it onto the bottom cap.

[0015] In some embodiments, the following steps are further included between step S03 and step S04:

[0016] Step S035: Push the piston to slide; the piston pushes the rotary positioning table on the workstation to position the bottle body. Then, the first guide frame, which can be raised and lowered on the upper side of the rotary positioning table, descends to guide the bottle body. Then, the upper push rod, which can be raised and lowered relative to the first guide frame, passes through the first guide frame and pushes the piston to the bottom of the bottle body. Finally, the lower push rod, which can be raised and lowered on the bottom of the rotary positioning table, passes through the rotary positioning table and pushes the piston to the top of the bottle body.

[0017] In some embodiments, the following step is further included between step S04 and step S05:

[0018] Step S044, air tightness test: The bottle is positioned by a rotating positioning table on the air tightness test station. Then, a pressure plate that can be raised and lowered on the upper side of the rotating positioning table presses down the bottom cover. Then, a telescopic air nozzle that can be raised and lowered on the bottom of the rotating positioning table extends into the bottle to inflate it. After inflation, the pressure is maintained, and the pressure change of the pressure sensor connected to the telescopic air nozzle is detected. If the pressure sensor shows an increase in pressure, it is an air leak; otherwise, it is not an air leak.

[0019] In some embodiments, step S03 specifically includes the following steps:

[0020] Step S031, piston feeding; the piston is placed inside the piston vibrating plate, and the piston inside the piston vibrating plate feeds towards the reversing mechanism through the piston conveying guide rail connected between the piston vibrating plate and the reversing mechanism;

[0021] Step S032, the first receiving plate receives material; the piston in the piston conveying guide rail first enters the connecting seat connected to the piston conveying guide rail, and the material distribution rod, which can be raised and lowered and installed on the upper side of the connecting seat, rises, so that the piston in the connecting seat smoothly enters the first U-shaped groove in the first receiving plate; then the first receiving plate slides so that multiple first U-shaped grooves connect with the connecting seat one by one to receive material. After all the first U-shaped grooves have completed receiving material, the material distribution rod descends and inserts into the piston, thereby restricting the piston in the connecting seat from continuing to feed material toward the first receiving plate;

[0022] Step S033: Detect the forward and reverse orientation of the piston; A height sensor located on one side of the first receiving plate detects the height of the piston, and determines the forward and reverse orientation of the piston based on the height; If the piston height is the first height, the piston is forward, and the reversing cylinder located on one side of the first receiving plate clamps the current piston and places it on the piston distribution guide rail between the reversing mechanism and the piston suction head; If the piston height is the second height, the piston is reverse, and the reversing cylinder clamps the current piston, rotates it to reverse its orientation, and then places it on the piston distribution guide rail;

[0023] Step S034, piston assembly; the piston in the piston distribution guide rail enters the second U-shaped groove of the second receiving plate, then the second guide frame, which can be lifted and lowered on the upper side of the rotating positioning platform, descends to guide the bottle body, and then the piston suction head picks up the piston in the second U-shaped groove and assembles it into the bottle body.

[0024] In some embodiments, step S04 specifically includes the following steps:

[0025] Step S041, bottom cover loading; the bottom cover is placed inside the bottom cover vibrating plate, and the bottom cover inside the bottom cover vibrating plate is loaded toward the material distribution mechanism via the bottom cover conveying guide rail between the material distribution mechanism and the bottom cover vibrating plate;

[0026] Step S042, the material distribution mechanism distributes materials; the bottom cover in the bottom cover conveying guide rail first enters the third U-shaped groove of the third receiving plate, and the sliding of the third receiving plate causes multiple third U-shaped grooves to connect with the bottom cover conveying guide rail one by one to receive materials; after all the third U-shaped grooves have received materials, the material transfer suction head, which is movably installed between the third receiving plate and the bottom cover conveyor belt, picks up the bottom cover in the third U-shaped groove and transfers it to the bottom cover conveyor belt;

[0027] Step S043, bottom cap assembly; the bottom cap conveyor belt conveys the bottom cap toward the bottom cap suction head, then the first guide gripper, which can be lifted and lowered on the upper side of the rotating positioning platform, descends and clamps the bottle body, and finally the bottom cap suction head picks up the bottom cap on the bottom cap conveyor belt and assembles it onto the bottle body.

[0028] In some embodiments, step S05 specifically includes the following steps:

[0029] Step S051, loading the decorative cover; the decorative cover is loaded onto the decorative cover conveyor belt by a robotic arm, the decorative cover is inverted on the decorative cover conveyor belt, and the decorative cover conveyor belt transports the decorative cover toward the indexing plate;

[0030] Step S052, dispensing adhesive; during the process of the decorative cover being conveyed by the decorative cover conveyor belt, the dispensing stick descends and dispenses adhesive into the inner cavity of the indexing plate;

[0031] Step S053, photo inspection and reversing: The inspection camera, which can be raised and lowered and installed between the dispensing rod and the reversing gripper, takes a photo to inspect the dispensing quality of the decorative cover. If the inspection is qualified, the reversing gripper picks up the qualified decorative cover, rotates it to reverse its direction, and then places it on the decorative cover conveyor belt. If the inspection is unqualified, the reversing gripper does not move, and the unqualified decorative cover enters the waste hopper under the drive of the decorative cover conveyor belt.

[0032] Step S054, decorative cap assembly; the second guide gripper, which is slidably mounted on the upper side of the indexing plate, extends and clamps the bottle body, and then the decorative cap gripper picks up the decorative cap after reversing on the decorative cap conveyor belt and assembles it onto the bottom cap of the bottle body.

[0033] In some embodiments, step S05 further includes the following steps:

[0034] Step S055, pressing; the decorative cover is pressed down by a pressing head that can be raised and lowered and installed on the upper side of the indexing plate, so that the decorative cover is firmly attached to the bottom cover;

[0035] Step S056, unloading finished products; the assembled finished products are unloaded onto the unloading conveyor belt on the side of the decorative cover assembly component by the robotic arm on one side of the indexing plate.

[0036] In some embodiments, during step S02, when applying oil, the lifting slide on the upper side of the rotating positioning platform drives the oil spray bar on it to descend and extend into the bottle body. Then, the oil spray nozzle on the oil spray plate starts to spray oil. Then, the rotating seat drives the oil spray plate to rotate. While rotating, the lifting slide drives the oil spray bar to rise slowly.

[0037] (III) Beneficial Effects

[0038] This invention provides an automated assembly method for cosmetic vacuum bottles. During assembly, a bottle feeding conveyor belt is used to feed the bottles, an oiling component applies oil to the inner wall of the bottle, a piston assembly component inserts the piston into the bottle, and a piston pushing component pushes the piston to slide within the bottle to simulate actual piston movement and lubricate the piston. Then, a bottom cap assembly component assembles the bottom cap onto the bottle, an airtightness detection component performs an airtightness test on the bottle after bottom cap assembly, and finally, a decorative cap assembly component assembles the decorative cap onto the bottom cap. This method enables fully automated assembly of cosmetic vacuum bottles, with continuous processes, a high degree of automation, low manual labor intensity, and high assembly efficiency. By incorporating a reversing mechanism, an airtightness detection component, and a detection camera, assembly quality can be guaranteed. This method overcomes the shortcomings of existing cosmetic vacuum bottle assembly methods, which suffer from low efficiency and poor assembly quality. Attached Figure Description

[0077] See Figures 2 to 5 This invention provides an automated assembly method for cosmetic vacuum bottles, comprising the following steps:

[0078] Step S01, feeding bottle A; depending on the type of bottle A, invert or place bottle A in the bottle positioning seat of the bottle feeding conveyor belt 3, and then feed it towards the workbench 1 through the bottle feeding conveyor belt 3.

[0079] Step S02, oiling bottle A; the bottle A is positioned by the rotating positioning table 2 on the oiling station, and then the oil spraying rod 40 of the oiling component 4 is inserted into the bottle A to perform rotating oil spraying.

[0080] Step S03: Assemble piston B; Position bottle A using rotary positioning table 2 at piston assembly station, then feed piston B to reversing mechanism 51 via piston vibrating disk 50 of piston assembly assembly 5. Then, reversing mechanism 51 detects the forward and reverse orientation of piston B and reverses the orientation of reversed piston B. Finally, piston suction head 52, which is movably mounted on the upper side of rotary positioning table 2, picks up forward-oriented piston B and inserts it into bottle A.

[0081] In some embodiments, such as Figure 2 As shown, it also includes the following steps:

[0082] Step S04: Assemble the bottom cap C. Position the bottle A using the rotary positioning table 2 at the bottom cap assembly station. Then, feed the bottom cap C onto the material distribution mechanism 61 via the bottom cap vibrating plate 60 of the bottom cap assembly assembly assembly 6. Next, the material distribution mechanism 61 distributes the bottom cap C onto the bottom cap conveyor belt 62. Finally, the bottom cap suction head 63, which is movably mounted on the upper side of the rotary positioning table 2, picks up the bottom cap C from the bottom cap conveyor belt 62 and assembles it onto the bottle A.

[0083] In some embodiments, such as Figure 2 As shown, it also includes the following steps:

[0084] Step S05: Assemble the decorative cap D; Position the bottle A using the rotatable indexing plate 70 at the decorative cap assembly station, then transport the decorative cap D towards the indexing plate 70 via the decorative cap conveyor belt 71 of the decorative cap assembly assembly assembly 7; During the transport of the decorative cap D via the decorative cap conveyor belt 71, the dispensing rod 72, which is vertically mounted on the decorative cap conveyor belt 71, dispenses adhesive into the inner cavity of the decorative cap D; then, the reversing gripper 73, which is vertically mounted on the decorative cap conveyor belt 71, reverses the direction of the dispensed decorative cap D; finally, the decorative cap gripper 74, which is movably mounted between the decorative cap conveyor belt 71 and the indexing plate 70, picks up the decorative cap D from the decorative cap conveyor belt 71 and assembles it onto the bottom cap C.

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

[0086] Step S035: Push piston B to slide; the piston pushes the rotary positioning table 2 on the work station to position the bottle A. Then, the first guide frame 81, which can be raised and lowered on the upper side of the rotary positioning table 2, descends to guide 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 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 table 2, passes through the rotary positioning table 2 and pushes piston B to the top of the bottle A.

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

[0088] Step S044, air tightness test: The bottle A is positioned by the rotating positioning table 2 on the air tightness test station. Then, the pressure plate 91, which can be raised and lowered on the upper side of the rotating positioning table 2, presses down the bottom cover C. Then, the telescopic air nozzle 92, which can be raised and lowered on the bottom of the rotating positioning table 2, extends into the bottle 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 sensor shows an increase in pressure, it is an air leak; otherwise, it is not an air leak.

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

[0090] Step S031, piston B is fed; piston B is placed in piston vibratory plate 50, and piston B in piston vibratory plate 50 is fed towards reversing mechanism 51 through piston conveying guide rail 53 connected between piston vibratory plate 50 and reversing mechanism 51.

[0091] Step S032, the first receiving plate 511 receives 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 distribution rod 516, which can be lifted and lowered and 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 receiving plate 511; then the first receiving plate 511 slides so that multiple first U-shaped grooves 514 connect with the connecting seat 515 one by one to receive material. After all the first U-shaped grooves 514 have completed receiving material, the material distribution rod 516 descends and inserts into the piston B, thereby restricting the piston B in the connecting seat 515 from continuing to feed towards the first receiving plate 511;

[0092] Step S033: Detect the orientation of piston B; the height sensor 512 located on one side of the first receiving plate 511 detects the height of piston B and determines its orientation based on the height; if the height of piston B is the first height, piston B is in the forward orientation, and the reversing cylinder 513 located on one side of the first 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 orientation, and the reversing cylinder 513 clamps the current piston B, rotates it 180 degrees to reverse its orientation, 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; piston B in piston feeding guide rail 54 enters the second U-shaped groove 551 of second receiving plate 55, then the second guide frame 57, which can be lifted and lowered on the upper side of the rotating positioning table 2, descends to guide bottle A, and then piston suction head 52 picks up piston B in second U-shaped groove 551 and assembles it into bottle A.

[0094] In some embodiments, such as Figure 4 As shown, step S04 specifically includes the following steps:

[0095] Step S041, bottom cover C is fed; bottom cover C is placed inside bottom cover vibrating plate 60, and bottom cover C inside bottom cover vibrating plate 60 is fed towards the material distribution mechanism 61 through bottom cover conveying guide rail 64 between material distribution mechanism 61 and bottom cover vibrating plate 60.

[0096] In step S042, the material distribution mechanism 61 distributes the material; the bottom cover C in the bottom cover conveying guide rail 64 first enters the third U-shaped groove 612 of the third receiving plate 611, and the sliding of the third receiving plate 611 causes multiple third U-shaped grooves 612 to connect with the bottom cover conveying guide rail 64 one by one to receive the material; after all the third U-shaped grooves 612 have received the material, the material transfer suction head 613, which is movably installed between the third receiving plate 611 and the bottom cover conveyor belt 62, picks up the bottom cover C in the third U-shaped groove 612 and transfers it to the bottom cover conveyor belt 62;

[0097] Step S043, bottom cap C assembly; bottom cap conveyor belt 62 conveys bottom cap C toward bottom cap suction head 63, then the first guide gripper 66, which can be lifted and lowered on the upper side of the rotary positioning table 2, descends and clamps bottle A, and finally bottom cap suction head 63 picks up bottom cap C from bottom cap conveyor belt 62 and assembles it onto bottle A.

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

[0099] Step S051, loading decorative cover D; the decorative cover D is loaded onto the decorative cover conveyor belt 71 by a robotic arm, the decorative cover D is inverted 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; during the process of conveying the decorative cover D on the decorative cover conveyor belt 71, the dispensing rod 72 descends and dispenses adhesive into the inner cavity of the indexing plate 70.

[0101] Step S053, photo inspection and reversing: The inspection camera 75, which can be lifted and installed between the dispensing rod 72 and the reversing gripper 73, takes a photo to inspect the dispensing quality of the decorative cover D. If the inspection is qualified, the reversing gripper 73 picks up the qualified decorative cover D, rotates it 180 degrees to reverse its direction, and then places it on the decorative cover conveyor belt 71. If the inspection is unqualified, the reversing gripper 73 does not move, and the unqualified decorative cover D enters the waste hopper under the drive of the decorative cover conveyor belt 71.

[0102] Step S054, assembling the decorative cap D; the second guide gripper 77, which is slidably mounted on the upper side of the indexing plate 70, extends and clamps the bottle body A, and then the decorative cap gripper 74 picks up the decorative cap D after reversing on the decorative cap conveyor belt 71 and assembles it onto the bottom cap C of the bottle body A.

[0103] Step S055, pressing; the decorative cover D is pressed down by the pressing head 781, which can be lifted and installed on the upper side of the indexing plate 70, so that the decorative cover D is firmly attached to the bottom cover C.

[0104] Step S056, unloading finished products; the assembled finished products are unloaded onto the unloading conveyor belt 10 on the side of the decorative cover assembly component 7 by the robotic arm on one side of the indexing plate 70.

[0105] In some embodiments, during step S02, when applying oil, the lifting slide 41 on the upper side of the rotating positioning platform 2 drives the oil spray rod 40 on it to descend and extend into the bottle A. Then, the oil spray nozzle 403 on the oil spray plate 402 starts to spray oil. Then, the rotating seat 401 drives the oil spray plate 402 to rotate. While rotating, the lifting slide 41 drives the oil spray rod 40 to rise slowly.

[0106] See Figures 6 to 30 The present invention also provides a fully automated assembly equipment for cosmetic vacuum bottles. The automated assembly method for cosmetic vacuum bottles is based on the fully automated assembly equipment for cosmetic vacuum bottles. The fully automated assembly equipment 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 equipped with bottle feeding stations, oiling stations, and piston assembly stations spaced along a straight line. Rotary positioning tables 2 are installed at both the oiling and piston assembly stations to position 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 spaced along a straight line on the conveyor belt 3, each with a bottle positioning hole. During feeding, bottle A is placed within the positioning hole. This fully automated assembly equipment is mainly suitable for bottles with openings at both the top and bottom. In this case, bottle A is inverted within the positioning seat, with the bottom opening facing upwards, to facilitate subsequent oiling and piston assembly. When the product is a bottle with only an opening at the top, the bottle is placed upright within the positioning seat, with its top opening facing upwards. The oiling assembly 4 is installed at the oiling station. The oiling assembly 4 includes an oil spraying rod 40 that can be inserted into the bottle A to rotate and spray oil. At this station, oiling is performed inside the bottle A, which facilitates the insertion of the piston and makes the piston movement smoother.

[0108] See Figures 6 to 9 Piston assembly assembly 5 is installed at the piston assembly station for assembling pistons B into bottle A. Piston assembly assembly 5 includes a piston vibratory plate 50 for feeding pistons B, a reversing mechanism 51 for detecting the orientation of pistons B and reversing reversed pistons B, and a piston suction head 52 movably mounted on the upper side of the rotary positioning table 2. The piston suction head 52 is used to pick up forward-oriented pistons B and insert them into bottle A. The reversing mechanism 51 detects the orientation of pistons B. If the detection is forward, no reversing is needed; if the detection is reversed, the reversing mechanism 51 rotates it 180 degrees to reverse the orientation, ensuring that each piston is inserted forward and guaranteeing 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. The bottom cap assembly station is equipped with a rotary positioning table 2 and a bottom cap assembly assembly 6. The rotary positioning table 2 positions the bottle A, and the bottom cap assembly assembly 6 assembles the bottom cap C onto the bottle A. The bottom cap assembly assembly 6 includes a bottom cap vibrating plate 60 for feeding the bottom cap C, a dispensing mechanism 61, a bottom cap conveyor belt 62, and a bottom cap suction head 63 movably mounted on the rotary positioning table 2. The dispensing mechanism 61 dispenses the bottom cap C onto the bottom cap conveyor belt 62, and the bottom cap suction head 63 picks up the bottom cap C from the bottom cap conveyor belt 62 and assembles it onto the bottle A. Dispensing via the dispensing mechanism 61 allows for the simultaneous assembly of multiple bottom caps C, effectively improving assembly efficiency. Multiple bottle positioning seats are spaced along a straight line on the bottom cap conveyor belt 62. These bottle positioning seats position the bottle A, preventing displacement of the bottle during the movement of the bottom cap conveyor belt 62 and ensuring accurate positioning.

[0110] like Figure 6 , Figure 7 , Figure 25 and Figure 26 As shown, a decorative cover assembly station is located behind the bottom cover assembly station. A decorative cover assembly assembly assembly 7 is installed at this station, used to assemble the decorative cover D onto the bottom cover C. The decorative cover assembly assembly 7 includes an indexing plate 70 rotatably mounted on the rear side of the worktable 1, a decorative cover conveyor belt 71 for feeding the decorative cover D towards the indexing plate 70, a dispensing rod 72 and a reversing gripper 73 mounted on the decorative cover conveyor belt 71, and a decorative cover gripper 74 movably mounted between the indexing plate 70 and the decorative cover conveyor belt 71. Multiple bottle positioning seats are evenly spaced along the circumference of the indexing plate 70, used to position bottles A. A robotic arm can be used to feed the decorative cover D onto the decorative cover conveyor belt 71, with the decorative cover D inverted on the conveyor belt 71 so that its opening faces upwards, facilitating dispensing by the dispensing rod 72. Multiple decorative cover positioning seats are spaced apart along a straight line on the decorative cover conveyor belt 71. The decorative cover D is placed inside the decorative cover positioning seats to prevent it from shifting. The glue dispensing rod 72 is used to dispense glue into the inner cavity of the decorative cover D. The reversing jaw 73 is used to reverse the direction of the glued decorative cover D. That is, the reversing jaw 73 clamps the decorative cover D and rotates it 180 degrees so that its opening faces downward, so as to facilitate the fitting of the decorative cover D onto the bottom cover C. The decorative cover jaw 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 set between the piston assembly station and the bottom cap assembly station. A rotary positioning table 2 and a piston pushing assembly 8 are installed at the piston pushing station. The rotary positioning table 2 is used to position the bottle A, and the piston pushing assembly 8 is used to push the piston to move inside the bottle, simulating the actual piston action. Furthermore, the inner wall of the bottle 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 can be raised and lowered and mounted on the upper side of the rotary positioning table 2, an upper push rod 82 that can be raised and lowered and mounted on the upper side of the first guide frame 81, and a lower push rod 83 that can be raised and lowered and mounted on the bottom of the rotary positioning table 2. The first guide frame 81 is used to guide the bottle A when the piston B is pushed. The first guide frame 81 is provided with a guide hole that matches the outer contour of the bottle A. Lowering the first guide frame 81 allows the bottle A to be placed within the guide hole, thereby supporting the bottle A and preventing it from tilting. The upper push rod 82 can pass through the first guide frame 81 and push the piston B to move downwards, while the lower push rod 83 can pass through the rotary positioning table 2 and push the piston B to move upwards. The above structure is mainly suitable for bottles with openings at both the top and bottom; when the bottle only has an upper opening, the lower push rod is not used, and only the upper push rod is needed to push the piston to the bottom.

[0112] like Figure 6 , Figure 7 , Figure 19 and Figure 24 As shown, an airtightness testing station is set between the bottom cap assembly station and the decorative cap assembly station. The airtightness testing station is equipped with a rotating positioning table 2 and an airtightness testing component 9. The rotating positioning table 2 is used to position bottle A, and the airtightness testing component 9 is used to perform airtightness testing on bottle A after the bottom cap C is assembled. The airtightness testing component 9 includes a pressure plate 91 that can be raised and lowered and installed on the upper side of the rotating positioning table 2, and a telescopic air nozzle 92 that can be raised and lowered and installed at the bottom of the rotating positioning table 2. The pressure plate 91 is used to press down the bottom cap C, and the telescopic air nozzle 92 is used to extend into the bottle A to inflate it. The telescopic air nozzle is connected to an air pipe, and a pressure sensor is installed on the air pipe. During the airtightness test, the pressure plate presses down on the bottom cap, then the telescopic air nozzle rises and extends into the bottle to inflate it. After inflation, the pressure is maintained, and the pressure change on the pressure sensor is detected. If there is no pressure change, there is no leakage; otherwise, there is leakage. This structure can automatically complete the airtightness check, with a high degree of automation. The airtightness check ensures the assembly quality and good assembly effect.

[0113] like Figures 8 to 15As shown, one side of the reversing mechanism 51 is connected to the piston vibratory plate 50 via the piston conveying guide rail 53, and the other side of the reversing mechanism 51 feeds material toward the piston suction head 52 via the piston dispensing guide rail 54. The reversing mechanism 51 includes a first receiving plate 511 slidably mounted on the end of the piston conveying guide rail 53, at least one height sensor 512 mounted on one side of the first receiving plate 511, and reversing cylinders 513 symmetrically mounted on both sides of the first receiving plate 511. First U-shaped grooves 514 are respectively provided on both sides of the first receiving plate 511, allowing either first U-shaped groove 514 to connect with the piston conveying guide rail 53 by sliding the first receiving plate 511. Two height sensors 512 are used, each corresponding to one of the two first U-shaped grooves 514. The use of two first U-shaped grooves allows for simultaneous detection and reversing processes on both sides, improving efficiency. The height sensor 512 faces the first U-shaped groove 514. The height sensor 512 is used to detect the forward and reverse orientation of piston B. The height sensor can detect the height of the piston. The reversing cylinder 513 is used to reverse the orientation of the reverse piston B. When the piston center column faces upward, the height is greater, and the piston is in the forward orientation. At this time, the reversing cylinder only clamps the piston and places it on the piston distribution guide rail, without reversing its orientation. When the center column faces downward, the height is smaller, and the piston is in the reverse orientation. At this time, the reversing cylinder clamps the piston, rotates it 180 degrees to reverse its orientation, and then places it on the piston distribution guide rail.

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

[0115] The end of the piston distribution guide rail 54 is fixed with a second receiving plate 55. The second receiving plate 55 is provided with a plurality of second U-shaped grooves 551 at intervals along the straight direction. The second U-shaped grooves are used to receive the piston on the piston distribution guide rail. The end of the piston distribution guide rail near the reversing mechanism can be tilted or the entire piston distribution guide rail can be tilted to facilitate the piston sliding along the piston distribution guide rail and ensure smooth movement. First support seats 56 are symmetrically installed on both sides of the second receiving plate 55. A first horizontal slide block 561 is slidably installed on the first support seat 56 in the horizontal direction. The piston suction head 52 is vertically mounted on the first horizontal slide block 561, which can drive the piston suction head 52 to move between the second receiving plate and the rotary positioning table. A second guide frame 57 is vertically mounted on the first support seat 56. The second guide frame 57 is used to guide the bottle body A during piston B assembly. The second guide frame 57 is provided with a guide hole that matches the outer contour of the bottle body A. Lowering the second guide frame 57 allows the bottle body A to be placed within the guide hole, thus supporting the bottle body 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 lowers to support the bottle body A, and then the piston suction head 52 picks up the piston from the second U-shaped groove 551 and assembles it into the bottle body A.

[0116] like Figures 18 to 23 As shown, the material distribution mechanism 61 is connected to the bottom cover vibrating plate 60 via the bottom cover conveying guide rail 64. The material distribution mechanism 61 includes a third receiving plate 611 slidably installed at the end of the bottom cover conveying guide rail 64. Multiple third U-shaped grooves 612 are spaced apart along a straight line on the third receiving plate 611. By sliding the third receiving plate 611, any third U-shaped groove 612 can be connected to the bottom cover conveying guide rail 64 to receive material. A material transfer suction head 613 is movably installed on the upper side of the third receiving plate 611. The material transfer 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 base 65 is installed at the end of the bottom cover conveyor belt 62 away from the material distribution mechanism 61. A second horizontal slide block 651 is slidably installed on the second support base 65. The bottom cover suction head 63 is vertically mounted on the second horizontal slide block 651. The second horizontal slide block 651 can drive the bottom cover suction head 63 to slide between the end of the bottom cover conveyor belt and the rotary positioning table to facilitate the assembly suction head to pick up the bottom cover and assemble the bottom cover. A first guide gripper 66 is vertically mounted on the second support base 65. The first guide gripper 66 is used to hold the bottle body A when assembling the bottom cover C to prevent the bottle body A from tilting and to ensure the 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 rod 72 and the reversing gripper 73. The detection camera 75 is used to photograph and detect the dispensing effect. The addition of the detection camera allows for photographic detection of the dispensed decorative cover. When the dispensing is found to be substandard, the reversing gripper stops working, and the substandard decorative cover enters the waste hopper at the end of the conveyor belt. When the dispensing is found to be satisfactory, the reversing gripper reverses its direction, and the decorative cover gripper 74 picks up the reversed decorative cover and assembles it onto the bottle body. This effectively ensures the dispensing effect, thereby guaranteeing the assembly quality and preventing weak adhesion due to insufficient glue. The detection camera is existing technology and will not be described in detail in this embodiment.

[0119] A third support base 76 is installed between the indexing plate 70 and the decorative cover conveyor belt 71. A third horizontal slide 761 is slidably installed on the third support base 76. A decorative cover gripper 74 is vertically mounted on the third horizontal slide 761. The third horizontal slide 761 can drive the decorative cover gripper 74 to slide between the end of the decorative cover conveyor belt 71 and the indexing plate 70. A second guide gripper 77 is slidably installed on the third support base 76. The second guide gripper 77 is used to hold the bottle body A when assembling the decorative cover D to prevent it from tilting and ensure assembly quality.

[0120] like Figure 28 As shown, a pressing assembly 78 is provided on the outer circumference of the indexing plate 70. The pressing assembly 78 is used to press down the decorative cover D to make it firmly attached to the bottom cover C. The pressing assembly 78 includes a pressing head 781 that can be lifted and installed on the upper side of the indexing plate 70. A feeding conveyor belt 10 is installed on one side of the decorative cover assembly 7. The pressed product can be unloaded onto the feeding conveyor belt 10 by a robot.

[0121] like Figure 30 As shown, the oiling assembly 4 also includes a lifting slide 41 that can be raised and lowered and mounted on the upper side of the rotating positioning table 2, and an oil spray rod 40 is mounted on the lifting slide 41. The oil spray rod 40 includes a rotating base 401 that can rotate relative to the lifting slide 41. Two oil spray plates 402 with adjustable spacing are mounted on the rotating base 401, and oil spray nozzles 403 are provided on the oil spray plates 402. By using two oil spray plates 402 with adjustable spacing, the spacing can be adjusted according to the bottle opening size, making it more adaptable; by using a rotating and raising oil spraying method, the oil spraying is uniform and the oil spraying effect is good.

[0122] like Figure 14 , Figure 17 , Figure 23 , Figure 24 and Figure 30As shown, the rotary positioning table 2 includes a rotary plate 21 rotatably mounted on the worktable 1. Positioning seats 22 are installed at the four corners of the rotary plate 21, and positioning holes 23 are provided in the positioning seats 22. By using the rotary plate 21, when one side is being assembled, the other side can be moved between adjacent workstations by the robot arm 11, which speeds up the assembly efficiency. A material transfer robot arm 11 is installed between two adjacent workstations. The material transfer robot arm 11 includes a main body and a gripper frame rotatably mounted on the main body. Multiple grippers are installed on the gripper frame.
