Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board welding, in particular to a flexible circuit board welding tool. Background Art

[0002] Flexible circuit boards, also known as soft circuit boards and flexible circuit boards, are popular for their light weight, thin thickness, free bending and folding and other excellent properties. With the rapid development of the electronics industry, circuit board design is becoming more and more high-precision and high-density. Traditional manual inspection methods can no longer meet production needs. Automated detection of FPC defects has become an inevitable trend in industrial development.

[0003] For example, the authorization announcement number "CN220087587U" is called a flexible circuit board welding tool. Although it is convenient for the staff to weld the first metal wire and the second metal wire at the two ends of the flexible circuit board respectively, the welding efficiency and welding success rate are higher. However, the existing flexible circuit board welding tool requires a large amount of solder when welding the flexible circuit board, and the solder needs to be heated to a certain temperature in advance and melted before being used for welding the flexible circuit board. When welding the flexible circuit board, a downward pressing cover plate is required to provide pressure to press the solder to the edge of the flexible circuit board. However, the soldering temperature is relatively high, and the surface temperature of the heated soldering iron of the pressing plate is also relatively high. When the operator directly relies on manual pressure, it is easy to come into contact with the high-temperature soldering iron and soldering points, thereby being scalded or burned, reducing the safety of the flexible circuit board welding tool.

[0025] When the flexible circuit board is pressed and welded, after the stepping plate 51 drives the cross bar 54 to move downward, the end of the cross bar 54 will pull the linkage rod 62 that crosses the outer side of the welding table 1 to move downward, and the linkage rod 62 will pull the top connecting pin 62 to move downward. At this time, the connecting pin 62 will drive the pressure plate 63 to flip and fall into the flexible circuit board welding groove 3. A connecting pin 62 is movably installed on the upper side wall of the pressure plate 63, and the outer side of the connecting pin 62 is movably connected to the linkage rod 61. The bottom end of the linkage rod 61 is movably connected to the end of the cross bar 54 through a pin shaft;

[0026] The treading plate 51 can be pressed down by the worker's foot, and the treading plate 51 will compress the spring 52 and shrink, and the treading plate 51 will drive the connecting block 53 to slide downward, and the sliding connecting block 53 will drive the cross bar 54 on one side to move downward.
