[0006] By adopting the above technical solution, the equipment integrates a complete process from loading the outer and inner caps, photo recognition, glue dispensing detection, gasket installation to final unloading, realizing fully automated assembly of cosmetic caps. During assembly, through photo recognition of the inner and outer caps, and by setting up an inner cap adjustment device to rotate the inner cap according to the state of the outer cap during loading, not only can the precise insertion and matching of the positioning strip on the inner cap and the positioning groove on the outer cap be achieved, but the inner cap adjustment speed is also fast, resulting in high overall production efficiency. Furthermore, by realizing automated production, the entire production process ensures precise material usage, a high yield rate, and achieves green production, energy saving, emission reduction, and efficiency improvement.

[0007] Optionally, the flipping device includes a slide cylinder, a first positioning seat, a rotary cylinder, a second positioning seat, and a cylinder gripper. The slide cylinder is used to control the first positioning seat to move up and down. The rotary cylinder is disposed on the first positioning seat and is used to control the second positioning seat to flip. The cylinder gripper is disposed on the second positioning seat and is used to grip or release the outer cover.

[0008] By adopting the above technical solution, the first positioning seat is moved up and down by the slide cylinder, the second positioning seat is flipped by the rotary cylinder, and the cylinder gripper clamps or releases the outer cover, thereby realizing the clamping and flipping of the outer cover and adjusting the state of the outer cover.

[0009] Optionally, the first material transfer device includes a first suction unit, a first horizontal moving unit, and a first vertical moving unit. The first suction unit is used to pick up and fix or release the outer cover. The first vertical moving unit can drive the first suction cup unit to move up and down. The first horizontal moving unit can drive the first vertical moving unit to move horizontally towards or away from the annular transmission track.

[0010] By adopting the above technical solution, the first suction unit picks up the fixed outer cover, the first up-and-down moving unit drives the suction unit to move up and down, and the first horizontal moving unit drives the entire material transfer device to move horizontally, moving the outer cover to the material positioning seat. This achieves precise and rapid movement of the outer cover from the outer cover positioning assembly line to the material positioning seat, thereby improving assembly efficiency.

[0011] Optionally, the outer cover camera mechanism further includes a ring light source, which is disposed on the support base. The outer cover camera is slidably disposed on the first support base. The ring light source has a vertically penetrating camera hole, and the outer cover camera is disposed above the ring light source.

[0012] By adopting the above technical solution, the outer cover camera, aided by a ring light source, takes pictures of the outer cover for identification. The ring light source provides uniform light, ensuring image quality and providing reliable data support for subsequent steps such as dispensing and assembly.

[0013] Optionally, the inner cover adjustment device is a swing gripper, which can clamp the inner cover and drive it to rotate; the second material transfer device includes a second horizontal moving unit and a second vertical moving unit, the second vertical moving unit can drive the swing gripper to move up and down, and the second horizontal moving unit can drive the second vertical moving unit to move horizontally towards or away from the annular transmission track, and the inner cover positioning seat, the inner cover camera, and the material positioning seat located on the annular guide rail are all located on the same straight line.

[0014] By adopting the above technical solution, the swing gripper holds the inner cover and drives it to rotate. The second vertical moving unit and the second horizontal moving unit work together to move the inner cover to the material positioning seat and insert it into the outer cover. This realizes the rapid rotation, adjustment, positioning and insertion of the inner cover, and improves the assembly efficiency and accuracy.

[0015] Optionally, the upper end of the gasket storage bin is provided with a storage trough for storing gaskets, and the bottom plate of the storage bin is provided with a material inlet for the gaskets to pass through, the diameter of the material inlet being smaller than the diameter of the gaskets; the third material transfer device includes a third suction unit for picking up and fixing or releasing the gaskets, and a cam flipping mechanism for driving the third suction unit to flip up and down and move.

[0016] By adopting the above technical solution, the gasket is stored in the storage bin, and the third suction unit, driven by the cam flipping mechanism, picks up and moves the gasket into the inner cover, realizing automatic feeding and precise placement of the gasket, and improving assembly efficiency and accuracy.

[0017] Optionally, a pre-compression block is slidably provided at the lower end of the gasket pressing seat, and a receiving groove for accommodating the pre-compression block is provided on the lower surface of the gasket pressing seat. A spring for driving the pre-compression block to move downward is also provided inside the gasket pressing seat.

[0018] By adopting the above technical solution, in its natural state, the pre-compression block protrudes from the lower surface of the gasket pressing seat under the drive of the spring. When the gasket pressing seat moves down, the pre-compression block first abuts against the gasket, and the adhesive under the gasket spreads outwards. When the gasket pressing seat contacts the gasket, it presses down again to spread the adhesive outwards. Compared with directly pressing down the entire gasket pressing seat, the adhesive can spread more evenly through the pre-compression block, and the problem of air bubbles between the gasket and the inner cover can be reduced.

[0019] Optionally, a scraper is provided at the lower end of the gasket pressing seat, and a sliding groove is provided on the side wall of the gasket pressing seat for the scraper to slide. The sliding groove extends downward through the lower surface of the gasket pressing seat. A connecting rod is hinged between the scraper and the pre-pressing block. When the pre-pressing block slides into the receiving groove, the scraper slides out from the side wall of the gasket pressing seat along the sliding groove. The gasket pressing mechanism also includes a rotary drive device for driving the gasket pressing seat to rotate. The second pressing drive device can drive the rotary drive device and the gasket pressing seat to move up and down.

[0020] By adopting the above technical solution, the rotation of the scraper plate can be increased to press the outer side of the gasket. Furthermore, by using a rotating gasket pressing seat, the pressing and scraping effect on the adhesive between the gasket and the inner cover can be further enhanced. At the same time, if too much adhesive is applied, causing a small amount of adhesive to overflow from the edge of the gasket, the scraper plate can scrape away the excess adhesive.

[0021] Optionally, the scraper includes a first plate and a second plate connected to each other. The first plate is hinged to the linkage rod. A guide block is provided on the side wall of the first plate. A guide groove is provided in the pad pressing seat for the guide block to slide in the horizontal direction. The second plate is connected to the side of the first plate away from the linkage rod. The second plate is made of elastic material and the outer side wall of the second plate has a pointed structure.

[0022] By adopting the above technical solution, the outer wall of the second plate has a pointed structure, which makes it easy to scrape off the glue overflowing from the inner wall of the inner cover. At the same time, the second plate is made of elastic material, which can avoid scratching the side wall of the inner cover.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. This equipment integrates the entire process from loading the outer and inner caps, photo recognition, glue dispensing detection, gasket installation to final unloading, realizing fully automated assembly of cosmetic caps. During the assembly process, through photo recognition of the inner and outer caps, and by setting an inner cap adjustment device to rotate the inner cap according to the state of the outer cap during the loading process, it can not only achieve precise insertion and matching between the positioning strip on the inner cap and the positioning groove on the outer cap, but also achieve fast inner cap adjustment speed and high overall production efficiency. At the same time, by realizing the automated production method, the entire production process is accurate in material use, high in yield rate, and achieves green production, energy saving, emission reduction and efficiency improvement. 2. The addition of a rotating scraper allows for pressing the outer side of the gasket, and the rotating gasket pressing seat further enhances the pressing and scraping effect on the adhesive between the gasket and the inner cover; at the same time, the scraper can also remove excess adhesive from the gasket.

Two thermal infrared temperature sensors 65 are mounted on the detection and installation platform 64 to detect whether the two inner covers 102 have been successfully dispensed with adhesive. After the inner cover 102 is dispensed with adhesive through the dispensing nozzle 62, it rotates with the annular transmission track 11 to a position below the thermal infrared temperature sensor 65 for detection.

[0038] Reference Figure 2 and Figure 9In this embodiment, the gasket feeding mechanism 7 includes a third support base 71, a gasket storage bin 72, and a third transfer device 73. The gasket storage bin 72 is mounted on the frame 1 and located above the annular guide rail. The third transfer device 73 can remove the gaskets 103 from the gasket storage bin 72 and place them into the inner cover 102. The upper end of the gasket storage bin 72 is provided with a storage trough 721 for storing the gaskets 103, which can stack and store the gaskets 103 from top to bottom. The bottom plate of the storage bin has a feeding port 722 for the gaskets 103 to pass through. The diameter of the feeding port 722 is slightly smaller than the diameter of the gaskets 103. Under natural conditions, the gaskets 103 can be located in the storage trough 721 under their own weight. The transfer device can remove the gaskets 103 at the bottom of the storage trough 721 from the feeding port 722.

[0039] Specifically, the third material transfer device 73 includes a third suction unit 731 for picking up, fixing, or releasing the pad 103, and a cam flipping mechanism 732 for driving the third suction unit 731 to flip up and down and move. The third suction unit 731 is 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 set on both sides below the third support base 71. Guide grooves are opened on the rectangular plates. The guide grooves include vertical sections at the top and bottom, and a flipping section in the middle arc. The cam mechanism works with the guide grooves to achieve precise flipping action. In use, the cam flipping mechanism 732 drives the third suction unit 731 to move upward and pick up the pad 103. Then it moves downward a certain distance and rotates along the guide groove to flip the pad 103 so that the pad 103 faces downward. It continues to move downward until the pad 103 is placed into the inner cover 102.

[0040] Reference Figure 2 and Figure 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 mounted on the frame 1, and the second pressing drive device 83 can be a cylinder, with its extension shaft connected to the gasket pressing seat 82. Two sets of gasket pressing seats 82 and second pressing drive devices 83 are provided, used to press the gaskets 103 in the two inner covers 102 individually. It should be noted that because the inner cover 102 has protruding threaded strips on its inner side for threaded connection with the main body 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 Figure 10 and Figure 11In an optional embodiment, a pre-compression block 84 is slidably provided at the lower end of the gasket pressing seat 82. A receiving groove for accommodating the pre-compression block 84 is provided on the lower surface of the gasket pressing seat 82. Optionally, a limiting block is provided on the side wall of the pre-compression block 84, and a limiting groove is provided inside the gasket pressing seat 82 for the limiting block to slide up and down, which is used to restrict the pre-compression block 84 from falling out of the receiving groove. At the same time, a spring 85 is also provided inside the gasket pressing seat 82 for driving the pre-compression block 84 to slide down. When the limiting block abuts against the lower side wall of the limiting groove, the spring 85 is still in a compressed state. The pre-pressing block 84 is coaxially positioned 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 adhesive concentrates in the middle of the inner cover 102 during application, direct pressing through the gasket pressing seat 82 results in poor adhesive diffusion, potentially leading to air bubbles between the gasket 103 and the inner cover 102. Furthermore, due to pressing time and air pressure issues between the gasket 103 and the inner cover 102, the adhesive struggles to diffuse to the outside of the gasket 103, resulting in a mediocre bonding effect. However, by first pressing the gasket 103 with the pre-pressing block 84, the adhesive diffuses outwards from the center. When the gasket pressing seat 82 contacts the gasket 103, further pressing spreads the diffused adhesive outwards. This results in more even adhesive diffusion and reduces the formation of air bubbles between the gasket 103 and the inner cover 102.

[0042] Reference Figure 10 and Figure 11 Optionally, a scraper 86 is provided on the lower surface of the gasket pressing seat 82, and a sliding groove is provided on the side wall of the gasket pressing seat 82 for the scraper 86 to slide. The scraper 86 can slide out of the side wall of the gasket pressing seat 82 along the sliding groove, or slide and be stored in the sliding groove. The sliding groove extends 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 86 abuts against the gasket 103. A connecting rod 87 is hinged between the scraper 86 and the side wall of the pre-pressing block 84. When the pre-pressing block 84 slides into the sliding groove, under the force of the connecting rod 87, the scraper 86 slides away from the central axis of the gasket pressing seat 82. The scraper pad pressing mechanism 8 also includes a rotary drive device 88 that drives the pad pressing seat 82 to rotate. The rotary drive device 88 can be a micro motor. The output shaft of the micro motor is connected to the upper surface of the pad 103 mounting seat. 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 activated, and the gasket pressing seat 82 and the scraper 86 rotate simultaneously. Because there is a gap between the outer wall of the gasket pressing seat 82 and the inner diameter of the inner cover 102 to pass through the threads in the inner cover 102, the rotation of the scraper 86 allows for pressing the outer side of the gasket 103. Furthermore, rotating the gasket pressing seat 82 further enhances the pressing and scraping effect on the adhesive between the gasket 103 and the inner cover 102. Simultaneously, if too much adhesive is applied, causing a small amount to overflow from the edge of the gasket 103, the scraper 86 can scrape away the excess adhesive. To improve the scraping effect, multiple scraper 86s can be arranged circumferentially along the gasket pressing seat 82.

[0044] Reference Figure 10 and Figure 11 Optionally, the scraper 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 connecting rod 87. The second plate 862 is made of an elastic material, such as rubber. The outer wall of the second plate 862 has a pointed structure, which facilitates the scraping of glue overflowing from the inner wall of the inner cover 102. At the same time, the elastic material of the second plate 862 can 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. A guide groove is opened in the pad pressing seat 82 for the guide block 863 to slide in the horizontal direction. Through the cooperation of the guide block 863 and the guide groove, the downward sliding of the scraper 86 can be restricted.

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

[0046] The implementation principle of an automatic assembly device for cosmetic caps according to an embodiment of this application is as follows: the outer cap feeding mechanism 2 is the first station, used to feed the outer cap 101 into the material positioning seat 12 with the opening facing upwards; the outer cap photographing mechanism 26 can photograph the internal condition of the outer cap 101 to locate the position of the positioning groove inside the outer cap 101; the inner cap feeding mechanism 3 and the inner cap feeding mechanism 4 cooperate to feed the inner cap 102 onto the material positioning seat 12 with the opening facing upwards, and adjust the position of the inner cap 102 according to the position of the positioning groove of the outer cap 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 into the outer cover 101; the glue dispensing detection mechanism 6 is used to dispense glue onto the bottom plate of the inner cover 102; the gasket feeding mechanism 7 is used to feed the gasket 103 into the inner cover 102; the gasket 103 pressing mechanism is used to press the gasket 103 into the inner cover 102, and remove the excess glue on the inner wall of the inner cover 102 by rotating the gasket pressing seat 82 and the scraper 86; the unloading mechanism 9 is used to send the assembled cosmetic cover to the discharge line 92.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
