CB-600 Fully Automatic COG Bonder

The CB-600 is a cutting-edge fully automatic COG (Chip on Glass) bonder designed to meet the precise requirements of modern electronics manufacturing. This advanced machine specializes in automatic ACF (Anisotropic Conductive Film) application, pre-bonding, and main bonding processes for LCD products ranging from 1″ to 6.5″ in size, with single-sided, single IC components. Its innovative design and high-precision features make it an essential tool for manufacturers seeking efficiency, accuracy, and reliability in their production lines.

Equipment Information

• Equipment Name: Fully Automatic COG Bonder
• Model: CB-600
• Application: Suitable for LCD products with sizes from 1″ to 6.5″, designed for automatic ACF application, pre-bonding, and main bonding of single-sided, single IC.
• Compatibility: Can be integrated with other machines in a production line for seamless operation.

Working Principle

The CB-600 operates through a series of coordinated mechanical and automated processes. The workflow begins with the loading of the product onto the conveyor belt or platform, either manually or via an automated upstream machine. Mechanical arm 1# picks up the product, corrects its position using the CCD (Charge-Coupled Device) system, and places it on the ACF platform. The ACF platform advances, and the bonding head descends to apply the ACF. After the ACF application, the platform retracts for position detection to ensure proper ACF adhesion. Mechanical arm 3# then picks up the LCD, checks the ACF adhesion, and places it on the pre-bonding stage. Meanwhile, the IC is loaded, and the automatic feeding system visually corrects the IC position. After pre-alignment, the IC is moved to the bonding head position, and the bonding head picks it up for pre-bonding. Mechanical arm 4# moves the product to one of the three main bonding platforms for final bonding. Finally, mechanical arm 5# transfers the bonded product to the downstream conveyor or production line.
