Description

Technical Field

[0001] The utility model relates to the field of industrial automation detection equipment, in particular to a high-efficiency automatic defect detection device for cosmetic bottle caps. Background Art

[0002] In the cosmetics production process, bottle caps are a crucial component of the product, and their appearance and functionality directly impact the overall quality and user experience. Traditional manual inspection methods are not only inefficient but also difficult to guarantee accuracy. Defective bottle caps may not seal effectively, causing cosmetics to leak. This not only wastes product but also contaminates the packaging and other items. Poor sealing allows air, moisture, and contaminants to enter the bottle, affecting the chemical stability of the cosmetics, causing ingredient deterioration, oxidation, or decomposition, and shortening the product's shelf life. Therefore, developing an efficient and automated device for detecting bottle cap defects is particularly important. For example, patent publication number CN111650215A discloses a cosmetic bottle cap defect detection system. However, this device suffers from the following deficiencies in the field of inspection equipment: It still lacks detection effectiveness, can suffer from problems such as poor sealing, and can expose cosmetic ingredients to air, causing oxidation or other chemical reactions, reducing product efficacy. Furthermore, bottle cap defects increase rework and scrap rates on the production line, increasing production costs and time. Utility Model Content

[0038] Working principle:

[0039] After the device is activated, all mechanisms are in place. The camera assembly 117 is precisely docked with the inspection platform 103 via the sliding base 116 to ensure the accuracy and stability of the camera position. The conveyor mechanism 2 is activated to transport the cosmetic bottle caps to be inspected from the input end to the inspection platform 103. The inspection platform 103 is provided with a through hole 1031. When the bottle caps reach the inspection platform 103, the picking mechanism 3 picks the bottle caps from the conveyor belt and accurately places them at the inspection position on the inspection platform 103. The images captured by the camera assembly 117 are processed and analyzed by the built-in software to detect defects on the bottle caps' surface and structure. The airtight groove 104 is provided below the inspection platform 103, and the airtight groove 104 is internally provided with an air outlet 1048 and an air inlet 1047. The suction cup 1153 on the pressing rod 115 can place the bottle cap through the through hole 1031 at the air outlet 1048 position on the airtight groove 104, and press down to fix the bottle cap at the same time. After the bottle cap is placed in the detection position, the airtight groove 104 detects the airtightness through the air inlet pipe 1041 and the air pressure gauge 1044 to ensure that the bottle cap has no leakage. The air pressure gauge 1044 monitors the air pressure in the airtight groove in real time, and determines whether the airtightness of the bottle cap is qualified according to the change in air pressure. After the detection is completed, the picking mechanism 3 moves the bottle cap from the detection position to the corresponding position of the belt 43 on the output mechanism 4 according to the detection results. Qualified bottle caps are transported to the good product slot 44, and unqualified bottle caps are transported to the defective product slot 45.
