The third material moving device 73 can take out the gasket 103 in the gasket storage bin 72 and put it into the inner cover 102. A storage trough 721 for storing gaskets 103 is provided at the upper end of the gasket storage bin 72, and the gaskets 103 can be stacked and stored in the storage trough 721 from top to bottom; there is a material taking port 722 for the gasket 103 to pass through on the bottom plate of the storage bin, and the diameter of the material taking port 722 is slightly smaller than the diameter of the gasket 103. In a natural state, the gasket 103 can be located in the storage trough 721 under its own gravity; the material moving device can take out the gasket 103 at the bottom of the storage trough 721 from the material taking port 722.

[0039] Specifically, the third material moving device 73 includes a third material suction unit 731 for sucking, fixing or releasing the gasket 103, and a cam flipping mechanism 732 for driving the third material suction unit 731 to flip up and move. The third material suction unit 731 uses a vacuum suction cup, and the cam flipping mechanism 732 uses a servo motor and a cam mechanism. At the same time, two rectangular plates are arranged on both sides below the third support seat 71, and guide grooves are provided on the rectangular plates. The guide grooves include upper and lower vertical sections, and a flipping section located in the middle arc; the cam mechanism cooperates with the guide groove to achieve precise flipping action. When in use, the cam flipping mechanism 732 drives the third material suction unit 731 to move upward and suck the gasket 103, and then after moving downward for a distance, it rotates along the guide groove to achieve flipping, so that the gasket 103 faces downward, and continues to move downward to put the gasket 103 into the inner cover 102.

[0040] Reference Figure 2 and Fig.10 In this embodiment, the gasket pressing mechanism 8 includes a second positioning platform 81, a gasket pressing seat 82 and a second pressing drive device 83. The second positioning platform 81 is arranged on the frame 1, and the second pressing drive device 83 can be a cylinder, and the telescopic shaft of the cylinder is connected to the gasket pressing seat 82; the gasket pressing seat 82 and the second pressing drive device 83 are provided in two groups, which are used to press the gaskets 103 in the two inner covers 102 separately. It should be noted that since the inner side of the inner cover 102 is provided with a protruding threaded strip for threaded connection with the main part of the cosmetic box, the outer diameter of the gasket pressing seat 82 is smaller than the inner diameter of the inner cover 102.

[0041] Reference Fig.10 and Fig.11In an optional embodiment, a pre-compression block 84 is provided at the lower end of the gasket pressing seat 82 for sliding up and down, and a receiving groove for receiving the pre-compression block 84 is provided on the lower surface of the gasket pressing seat 82. Optionally, a limit block is provided on the side wall of the pre-compression block 84, and a limit groove is provided inside the gasket pressing seat 82 for the limit block to slide up and down, so as to limit the pre-compression block 84 from falling out of the receiving groove downward; at the same time, a spring 85 for driving the pre-compression block 84 to slide downward is also provided in the gasket pressing seat 82, and when the limit block abuts against the side wall of the lower end of the limit groove, the spring 85 is still in a compressed state. The pre-pressing block 84 is coaxially arranged in the middle of the gasket pressing seat 82. When the gasket pressing seat 82 is pressed down, the pre-pressing block 84 first contacts the gasket 103. Since the glue is concentrated in the middle of the inner cover 102 during dispensing, if the gasket pressing seat 82 is directly pressed, the effect of glue diffusion is poor, and bubbles may exist between the gasket 103 and the inner cover 102. In addition, due to the pressing time and the air pressure between the gasket 103 and the inner cover 102, the glue is difficult to diffuse to the outside of the gasket 103, and the gluing effect is average. However, by pressing the gasket 103 first with the pre-pressing block 84, the glue in the middle first diffuses toward the peripheral side. When the gasket pressing seat 82 contacts the gasket 103, the diffused glue is further diffused outward by pressing again. In comparison, the glue can diffuse more evenly, and the problem of bubbles between the gasket 103 and the inner cover 102 can be reduced.

[0042] Reference Fig.10 and Fig.11 , further optionally, a scraper plate 86 is provided on the lower surface of the gasket pressing seat 82, and a slide groove for the scraper plate 86 to slide is provided on the side wall of the gasket pressing seat 82, and the scraper plate 86 can slide out of the side wall of the gasket pressing seat 82 along the slide groove, or be slidably received in the slide groove. The slide groove runs downward through the lower surface of the gasket pressing seat 82, that is, when the gasket pressing seat 82 presses the gasket 103, the lower surface of the scraper plate 86 abuts against the gasket 103. A linkage rod 87 is hinged between the scraper plate 86 and the side wall of the pre-pressing block 84. When the pre-pressing block 84 slides into the slide groove, under the action of the linkage rod 87, the scraper plate 86 slides in a direction away from the central axis of the gasket pressing seat 82. The scraper gasket pressing mechanism 8 also includes a rotation drive device 88 for driving the gasket pressing seat 82 to rotate. The rotation drive device 88 can be a micro motor. The output shaft of the micro motor is connected to the upper surface of the gasket 103 mounting seat, and the second drive device is connected to the upper end of the micro motor.

[0043] When the gasket pressing seat 82 abuts against the gasket 103, the rotary drive device 88 is started, and the gasket pressing seat 82 and the scraper plate 86 rotate at the same time; because there is a gap between the outer wall of the gasket pressing seat 82 and the inner diameter of the inner cover 102 in order to pass through the thread in the inner cover 102, increasing the rotation of the scraper plate 86 can press the outer side of the gasket 103, and the method of rotating the gasket pressing seat 82 can further increase the pressing and scraping effect of the glue between the gasket 103 and the inner cover 102. At the same time, if too much glue is dispensed, resulting in a small amount of glue overflowing the edge of the gasket 103, the excess glue can be scraped away by the scraper plate 86. In order to increase the scraping effect, multiple scraper plates 86 can be set along the circumference of the gasket pressing seat 82.

[0044] Reference Fig.10 and Fig.11 Optionally, the scraper plate 86 is divided into a first plate 861 and a second plate 862 connected to each other. The first plate 861 is hinged to the linkage rod 87, and the second plate 862 is made of elastic material, such as rubber. The outer wall of the second plate 862 is a pointed structure, which is convenient for scraping glue overflowing from the inner wall of the inner cover 102. At the same time, the second plate 862 is made of elastic material to avoid scratching the side wall of the inner cover 102. A guide block 863 is fixed on the side wall of the first plate 861, and a guide groove for the guide block 863 to slide in the horizontal direction is provided in the gasket pressing seat 82. The scraper plate 86 can be limited from sliding downward through the cooperation of the guide block 863 and the guide groove.

[0045] Reference Figure 2 In this embodiment, the unloading mechanism 9 includes a fourth material moving device 91 and a discharging assembly line 92. The fourth material moving device 91 can move the cosmetic cover located in the material positioning seat 12 to the discharging assembly line 92. The fourth device includes a fourth suction unit, a fourth horizontal moving unit and a fourth up and down moving unit. The fourth suction unit is used to suck or release the assembled cosmetic cover, and its specific structure is the same as the first suction unit 241; the specific structures of the fourth horizontal moving unit and the fourth up and down moving unit are the same as the first horizontal moving unit 242 and the first up and down moving unit 243.

[0046] The implementation principle of the automatic assembly equipment of the cosmetic cover of the embodiment of the present application is as follows: the outer cover feeding mechanism 2 is the first work station, which is used to feed the outer cover 101 into the material positioning seat 12 with the opening facing upward; the outer cover photographing mechanism 26 can take pictures of the internal situation of the outer cover 101 to locate the position of the positioning groove in the outer cover 101; the inner cover feeding mechanism 3 and the inner cover feeding mechanism 4 cooperate to feed the inner cover 102 to the top of the material positioning seat 12 with the opening facing upward, and adjust the position of the inner cover 102 according to the position of the positioning groove of the outer cover 101 during the feeding process. The positioning strip on the inner cover 102 can be inserted into the positioning groove on the outer cover 101; the inner cover pressing mechanism 5 is used to press the inner cover 102 tightly into the outer cover 101; the glue dispensing detection mechanism 6 is used to dispense glue on the bottom plate of the inner cover 102, and the gasket feeding mechanism 7 is used to send the gasket 103 to the inner cover 102; the gasket 103 pressing mechanism is used to press the gasket 103 tightly into the inner cover 102, and by rotating the gasket pressing seat 82 and the scraper plate 86, the overflow glue on the inner wall of the inner cover 102 is removed; the unloading mechanism 9 is used to send the assembled cosmetic cover to the discharge assembly line 92.
