Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging automation equipment, in particular to a cleaning agent packaging cap intelligent precise positioning and installation equipment. BACKGROUND

[0002] Automobile cleaning agent is a special cleaning preparation for automobiles composed of surfactants, bactericides, brightening agents and other components, including anionic (such as alkyl benzyl ammonium), non-ionic (such as alkyl phenol polyoxyethylene ether) and cationic surfactants and other types. Its functions cover the cleaning of stains on car body, glass, interior and engine parts, and can remove oil stains, gum, oxide layer and other stains.

[0003] Cleaning agent packaging and sealing is a key link to ensure product sealing and transportation safety. Traditional manual or semi-automatic sealing equipment has many limitations and cannot meet the precision and efficiency requirements of modern production lines. Its positioning accuracy is low, the risk of sealing failure is high, and it relies on manual visual alignment or simple mechanical guidance. The positioning deviation of the packaging bottle and the cap is large, which can easily lead to the installation of the cap at an angle, and the cleaning agent (especially the product with strong corrosion) can easily leak from the gap, resulting in a high probability of sealing failure. The leaked material can corrode the production line equipment, increasing maintenance costs. In addition, the packaging bottle can easily deviate during transportation and capping due to vibration, especially for lightweight bottles made of PET material, which have a high deviation rate, resulting in inaccurate capping of the cap and even damage to the bottle. Therefore, the present application provides a cleaning agent packaging cap intelligent precise positioning and installation equipment to solve the problems in the above background technology.
