Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a welding head replacement device for a double-station push-pull pulse machine. Background Art

[0002] The double-station push-pull pulse machine is a machine suitable for high-density FPC / FFC and PCB crimping and touch screen production processes. The double-station push-pull pulse machine is used in the following product production processes: USB cable welding, soft cable FFC and flexible circuit board FPC or hard circuit board PCB welding, TCP and circuit board PCB or flexible circuit board FPC welding, flexible circuit board FPC and circuit board PCB welding, etc. The double-station push-pull pulse machine loads a certain pulse voltage on the welding head, and the welding head heats up, which will heat up the object connected to it. When the temperature rises to the melting point of the solder, the tin between the connected objects will melt and connect them together. The welding head will produce wear and tear during long-term use, so it is necessary to replace the welding head by replacing the device.

[0003] When processing the existing PCB board, the double-station push-pull pulse machine will drive the welding head to move to the top of the PCB board for welding processing. The welding head is usually composed of flat copper parts, welding heads, temperature sensing sockets and temperature sensing plugs. The long-term use of the welding head requires the welding head to be replaced by a replacement device. The welding head replacement method is: first pull out the temperature sensing plug, and then use a hexagonal key to unscrew the screws. The welding head can be taken out by unscrewing the screws. Since the screw size of the replacement device is small, it is easy to cause the bolt to slip when the hexagonal key is unscrewed, which will increase the difficulty of disassembling the welding head and affect work efficiency. The welding head is not convenient to replace. Utility Model Content
