[0002] For women, makeup has become an essential part of daily life, and vacuum cosmetic packaging bottles are commonly used packaging containers for cosmetics. Referring to Figure 1, a vacuum cosmetic packaging bottle generally includes a bottle body with an upper opening and a lower opening at the top and bottom, respectively. The outer diameter of the upper opening is smaller than that of the lower opening, and a bottom cap is fitted at the lower opening. A piston is slidably installed inside the bottle.

Due to the small diameter of the lower opening, this is very inconvenient, requiring significant manual labor and resulting in low assembly efficiency. Furthermore, whether the bottom cap is properly installed relies entirely on visual inspection. If the bottom cap is not properly installed, the airtightness of the cosmetic packaging bottle will be compromised, affecting its effectiveness. Summary of the Invention

[0035] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0036] Referring to Figures 2 to 10, this utility model provides a cosmetic vacuum bottle bottom cap assembly and airtightness testing device, which includes a vibratory plate 1, a conveyor rail 2, a material dispensing component 3, a conveyor belt 4 and a bottom cap assembly component 5 connected in sequence.

[0037] Referring to Figures 2 to 4 and Figure 6, the vibratory feeder 1 is used to load the bottom cover 8. The material distribution assembly 3 includes a receiving plate 31 slidably mounted on the end of the conveyor rail 2. Multiple receiving grooves 311 are spaced apart along a straight line on the receiving plate 31. By sliding the receiving plate 31, the multiple receiving grooves 311 can be connected to the conveyor rail 2 one by one for material receiving. In this embodiment, to ensure assembly efficiency, there are four receiving grooves 311. A material transfer suction head 32 is movably mounted on the upper side of the receiving plate 31, and there are also four material transfer suction heads 32. The material transfer suction heads 32 are used to transfer the bottom cover 8 from the receiving grooves 311 onto the conveyor belt 4. The conveyor belt 4 is used to feed the bottom cap 8 toward the bottom cap assembly assembly 5. The bottom cap assembly assembly 5 includes a bottle positioning seat 6 installed at the end of the conveyor belt 4 and an assembly suction head 51 movably installed on the upper side of the bottle positioning seat 6. The bottle body 9 is inverted inside the bottle positioning seat 6, that is, the bottle body 9 is inverted inside the bottle positioning seat 6. The upper opening of the bottle body 9 is located on the lower side, and the lower opening of the bottle body 9 is located on the upper side, so as to facilitate the assembly of the bottom cap 8. The assembly suction head 51 is used to pick up the bottom cap 8 on the conveyor belt 4 and assemble it onto the bottle body 9.

[0038] This structure, through the cooperation of a vibratory feeder, conveyor rail, dispensing component, conveyor belt, bottom cap assembly component, and airtightness detection component, allows for the following process: during assembly, the vibratory feeder loads the bottom caps, which then travel along the conveyor rail to the dispensing component; next, the receiving plate and transfer suction head work together to dispense the bottom caps onto the conveyor belt, which feeds towards the bottom cap assembly component; finally, the assembly suction head picks up the bottom caps from the conveyor belt and assembles them onto the bottle body. This system can automatically complete the bottom cap assembly, resulting in a high degree of automation, low manual labor intensity, and high assembly efficiency.

[0039] In some embodiments, as shown in Figures 6 to 8, the bottom cap assembly assembly 5 further includes a guide gripper 52 that is vertically mounted on the upper side of the bottle positioning seat 6. The guide gripper 52 is used to hold the bottle 9 during the assembly of the bottom cap 8 to prevent the bottle 9 from tilting. In this structure, the addition of the guide gripper 52 allows the guide gripper 52 to descend and hold the bottle 9 during assembly, preventing the bottle 9 from tilting. Then, the assembly suction head picks up the bottom cap from the conveyor belt and assembles it onto the bottle 9, ensuring assembly quality.

The first horizontal slide block 531 can drive the assembly suction head 51 to slide between the end of the conveyor belt 4 and the bottle positioning seat 6, so as to facilitate the assembly suction head 51 to pick up the bottom cover and assemble the bottom cover.

[0041] In some embodiments, as shown in Figures 3, 9, and 10, an airtightness detection component 7 is installed on one side of the bottom cap assembly assembly 5. The airtightness detection component 7 is used to perform airtightness detection on the bottle body 9 after the bottom cap 8 is assembled, ensuring assembly quality. A robotic arm can be used to transfer materials between the bottom cap assembly assembly 5 and the airtightness detection component 7. The airtightness detection component 7 includes a bottle body positioning seat 6, a pressure plate 71 that is liftably mounted on the upper side of the bottle body positioning seat 6, and a telescopic air nozzle 72 that is liftably mounted on the bottom of the bottle body positioning seat 6. The bottle body 9 is inverted inside the bottle body positioning seat 6. The pressure plate 71 is used to press down the bottom cap 8 to prevent the bottle body 9 from detaching from the bottle body positioning seat 6 during inflation. The telescopic air nozzle 72 is used to extend into the bottle body 9 to inflate it. The telescopic air nozzle 72 is connected to an air pipe, and a pressure sensor is installed on the air pipe. During the airtightness test, the pressure plate 71 presses down on the bottom cover 8, then the telescopic air nozzle 72 rises and extends into the bottle body 9 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. Passing the airtightness check ensures assembly quality and good assembly effect.

[0043] In some embodiments, as shown in FIG6, the conveyor belt 4 includes multiple side-by-side sub-conveyor belts 41, and the multiple sub-conveyor belts 41 correspond one-to-one with multiple receiving troughs 311. In this embodiment, there are four sub-conveyor belts 41; each sub-conveyor belt 41 is provided with multiple bottom cover positioning seats 42 for positioning the bottom cover 8 at intervals along a straight line.

[0044] In some embodiments, as shown in Figures 8 and 9, the bottle positioning seat 6 is provided with a positioning hole 601 that is adapted to the bottle 9, and the bottle 9 is inverted in the positioning hole 601; the bottle positioning seat 6 is installed at the four corners of the rotating disk 602, and the bottles on both sides can be transferred by rotating the rotating disk 602, which also makes it convenient for the robot to pick up the bottles.

[0045] In some embodiments, as shown in FIG4, the receiving groove 311 is U-shaped and the opening faces the conveying guide rail 2, so that the bottom cover on the conveying guide rail 2 can enter the receiving groove 311; a baffle 35 is installed on one side of the receiving plate 31, which can block the opening on one side of the receiving groove 311 to prevent the bottom cover from falling out of the receiving groove 311.

[0046] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
