Description

Technical Field

[0001] The utility model relates to the technical field of tinning of a crystal bonding machine, in particular to a tinning head which is compatible with two tin wire diameters. Background Art

[0002] With the rapid development of the diode and rectifier bridge industry, production equipment is also constantly improving towards refinement. The die bonding machine is an important equipment for producing diodes and rectifier bridges. Its workflow is: first, grab the lead frame to the equipment track entrance through the feed gripper, and transfer the lead frame to the high-temperature track tinning position through the conveyor gripper. The stepper mechanism fixes the lead frame, and the tinning head transfers the tin wire to the lead frame. After tinning, the conveyor gripper sends the lead frame to the die bonding position. The stepper mechanism will fix the frame, and then the die bonding machine swing arm / telescopic arm will suck the chip out of the blue film and place it on the frame. Then, the frame will be taken out manually or mechanically and transferred to the solder paste dispenser. The solder paste dispenser is an automated equipment that specifically controls the fluid solder paste and drips and applies the fluid solder paste on the surface or inside of the product. It can realize irregular patterns such as dots, lines, and surfaces at the specified position of the frame.

[0003] However, the conventional soldering head on the die bonding machine has only one guide tube (0.51MM or 0.76MM). If the products are of different sizes during the production process, the entire soldering head (0.51MM or 0.76MM) needs to be replaced, which takes a long time to install and calibrate, and the production efficiency decreases.
