Description

Technical Field

[0001] This utility model belongs to the field of glue injection machine technology, and relates to a two-component three-proof glue injection device for automotive sensors. Background Technology

[0002] Conformal adhesive is a high-performance protective material manufactured using advanced chemical synthesis and cross-linking technology. It possesses certain waterproof, moisture-proof, and dustproof characteristics (referred to as "three-proof"). These properties enable it to maintain the stability and reliability of electronic components, circuit boards, and other precision equipment under various harsh environmental conditions. Conformal adhesive is widely used in the automotive sensor field to prevent damage to automotive electronic systems from moisture, salt spray, and dust, ensuring driving safety and stability.

[0003] The conformal adhesive, through careful formulation and mixing in a two-component AB glue container, forms a coating material that can cure quickly at room temperature and provide protective performance. The two-component AB glue container is designed as a combination of two specific-sized integrated liquid storage tubes, depending on the commonly used fluid ratios. One liquid is the adhesive itself, and the other is the hardener. The two liquids are mixed in a certain ratio to harden and are used. It is mainly used as a container for storing adhesive in manual or pneumatic dispensing devices.

[0004] Currently, on-site operators use dispensing valves for manual filling. Air remains in the filled glue, which forms bubbles during the dispensing process. These bubbles directly affect the appearance and quality of the product, causing inaccurate mixing ratios of AB glue and resulting in product defects. Utility Model Content
