Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic containers, and in particular to an automatic assembly device for cosmetic caps. Background Art

[0002] Cosmetic containers are usually not simple single-layer shell structures. They usually use a composite shell formed by combining an inner shell and an outer shell to isolate the cosmetics from the outside and effectively protect the cosmetics.

[0003] For example, Chinese patent CN207256921U discloses a lipstick cap automatic assembly system, which includes a frame, a turntable mechanism arranged on the frame, a power transmission mechanism for driving the turntable mechanism to rotate, a lipstick cap supply mechanism, a lipstick cap detection mechanism, a lipstick cap height detection mechanism, a counterweight ring supply mechanism, a counterweight ring detection mechanism, a lipstick cap liner supply mechanism, a lipstick cap liner detection mechanism, a glue dispensing mechanism, a glue dispensing detection mechanism, a combination mechanism, a pressing mechanism, a combination height detection mechanism, and a waste removal mechanism.

[0004] To improve assembly efficiency, cosmetic container lids with a double-layer structure often utilize a dual-station assembly process during the assembly of the inner and outer shells, meaning both lids are assembled simultaneously. This results in a situation where, when the lids are finally assembled and unloaded, if one of the two lids is defective, the unloading robot must perform two unloading operations, one to pick up a good and one to unload the defective product. This results in inefficient unloading and impacts production efficiency. Summary of the Invention

[0032] 1. In the present invention, when unloading cosmetic caps, two finished product suction cups on the finished product suction cup mounting plate in the finished product unloading mechanism simultaneously pick up two cosmetic caps. The finished product suction cup mounting plate can be rotated and adjusted in angle by a finished product dispensing motor. By controlling the distance between the finished product unloading conveyor and the defective product unloading pipe, the distance between the two finished product suction cups is utilized to ensure that defective products at the end of the finished product suction cup mounting plate are positioned above the defective product unloading port, while the good products on the inner side of the finished product suction cup mounting plate remain above the finished product unloading conveyor. When the two finished product suction cups release two cosmetic caps simultaneously, the good and defective products are simultaneously classified and unloaded. The finished product unloading mechanism can simultaneously classify and unload two cosmetic caps by taking and unloading materials at a time, thereby improving the unloading efficiency of cosmetic caps.

[0033] 2. In the present invention, the aluminum shell transfer assembly achieves simultaneous removal of blank aluminum shells, unloading of aluminum shells after glue dispensing, and loading of blank aluminum shells and assembly of aluminum shells after glue dispensing through the synchronized movement of the aluminum shell suction unit and the aluminum shell assembly unit, effectively simplifying the aluminum shell transfer assembly. The pneumatic aluminum shell gripper in the aluminum shell transfer assembly rotates 180 degrees via a gripper rotation motor. This not only flips the aluminum shell so that the opening faces downward, facilitating its placement on the inner cover, but also achieves horizontal position change, utilizing the resulting position change to align the inner cover. This eliminates the need for an additional horizontal motion device, simplifying the transfer assembly.

The operating principles of the second height detection assembly 68 and the second auxiliary pressing assembly 69 are similar to those of the first height detection assembly 87 and the first auxiliary pressing assembly 88.

[0097] An inner cover detection assembly is located between the magnetic ring assembly mechanism 4 and the inner cover loading robot 12. This assembly uses a sensor to detect whether the inner cover 91 is properly installed on the material conveying base 112. Its operating principle is similar to that of the inner ring detection assembly 54. Similarly, a magnetic ring detection assembly can be located between the magnetic ring assembly mechanism 4 and the inner ring assembly mechanism 5 to detect whether the magnetic ring 92 is properly installed.

[0098] Working principle: The assembly process of the cosmetic cover 9 is as follows: the inner cover 91 in the inner cover loading line 2 is transported to the side of the inner cover loading robot 12 through the inner cover loading belt 21, and the inner cover loading robot 12 grabs two inner covers 91 at a time and places them on the material conveying seat 112. Then the material conveying seat 112 conveys the inner covers 91 along the circular guide rail 111 to perform a multi-pass assembly process. The material conveying seat 112 first conveys the inner cover 91 to the magnetic ring assembly mechanism 4 for fitting the magnetic ring 92, and then the material conveying seat 112 conveys the inner cover 91 to the inner ring assembly mechanism 5 for fitting the inner ring 93, and then the material conveying seat 112 conveys the inner cover 91 to the weighted iron assembly mechanism 6 to install the weighted iron 94, and then the material conveying seat 112 moves to the aluminum shell dispensing and assembly mechanism 7, the aluminum shell dispensing and assembly mechanism 7 first sucks the aluminum shell 95 on the aluminum shell feeding belt 31 in the outer shell feeding line 3 to the dispensing position for dispensing, and then flips the aluminum shell 95 180 degrees and fits it on the inner cover 91 to complete the assembly.

[0099] After the cosmetic caps 9 are assembled, they are unloaded by the finished product unloading mechanism 8 based on the inspection results. The specific process is as follows: the material conveyor 112 on the annular guide rail 111 drives the cosmetic caps 9 to the bottom of the finished product suction cup 84 of the finished product unloading mechanism 8. At this point, the finished product pickup cylinder 82 drives the finished product dispensing motor 83 downward. The two finished product suction cups 84 on the finished product suction cup mounting plate 831 at the output end of the finished product dispensing motor 83 simultaneously pick up two cosmetic caps 9 on the material conveyor 112, with one finished product suction cup 84 picking up one cosmetic cap 9. The finished product suction cups 84 then return to their original positions and are moved horizontally by the finished product unloading linear motion module 81 to unload the cosmetic caps 9.

[0100] When the finished product unloading mechanism 8 unloads the two sucked cosmetic caps 9:

[0101] 1) Both cosmetic caps 9 are good products: the finished product unloading linear motion module 81 drives the finished product pickup cylinder 82 and the finished product suction cup 84 to move as a whole to the top of the finished product unloading conveyor 85, and the cosmetic caps 9 are placed on the finished product unloading conveyor 85 for unloading;

[0102] 2) Both cosmetic caps 9 are defective: the finished product unloading linear motion module 81 drives the finished product pickup cylinder 82 and the finished product suction cup 84 to move as a whole to above the defective product unloading port 861, and drops the cosmetic caps 9 into the defective product unloading pipe 86 for unloading;

[0103] 3) One of the two cosmetic caps 9 is a good product and the other is a defective product: Taking the cosmetic cap 9 sucked by the finished product suction cup 84 on the end of the finished product suction cup mounting plate 831 away from the end of the linear moving module 81 for finished product unloading as an example, the finished product picking cylinder 82 is first driven by the linear moving module 81 for finished product unloading to move above the finished product unloading conveyor belt 85. At this time, the two finished product suction cups 84 on the finished product suction cup mounting plate 831 are both above the finished product unloading conveyor belt 85. Then, the finished product dividing motor 83 drives the finished product suction cup mounting plate 831 to rotate, and uses the distance between the two finished product suction cups 84 to make the defective product at the end of the finished product suction cup mounting plate 831 be above the defective product dropping port 861. At the same time, the good product on the inner side of the finished product suction cup mounting plate 831 remains above the finished product unloading conveyor belt 85. In this way, when the two finished product suction cups 84 release the two cosmetic caps 9 at the same time, the good products and defective products are classified and unloaded at the same time.

[0104] When the cosmetic caps 9 are unloaded, the two finished product suction cups 84 on the finished product suction cup mounting plate 831 in the finished product unloading mechanism 8 simultaneously pick up two cosmetic caps 9. The finished product suction cup mounting plate 831 can be rotated and adjusted in angle by the finished product dispensing motor 83. By controlling the distance between the finished product unloading conveyor 85 and the defective product unloading pipe 86, the distance between the two finished product suction cups 84 is used to ensure that the defective product at the end of the finished product suction cup mounting plate 831 is positioned above the defective product unloading port 861, while the good product inside the finished product suction cup mounting plate 831 remains above the finished product unloading conveyor 85. When the two finished product suction cups 84 release the two cosmetic caps 9 at the same time, the good and defective products are simultaneously classified and unloaded. The finished product unloading mechanism 8 can simultaneously achieve classified unloading of two cosmetic caps 9 by taking and unloading materials at one time, thereby improving the unloading efficiency of the cosmetic caps 9.
