Description

Technical Field

[0001] The utility model relates to the technical field of flexible flat cable automatic welding, in particular to an online automatic welding device for flexible flat cable. Background Art

[0002] With the increasing popularity of various smart wearable electronic products, their functionality is increasingly diversified. Consequently, these products integrate a variety of rigid and flexible circuit boards. Flexible circuit boards are typically designed with flexible flat cables for soldering to the rigid circuit boards to achieve electrical signal connections. However, due to this diverse functionality and the overall trend toward thinner and lighter products, the internal circuit boards and components of these smart wearable electronic products require extremely precise design, placing a high demand on the soldering precision of the flexible flat cables.

[0003] Traditional technology relies on manual positioning. The product is placed in a jig, and then the user uses tweezers to grasp the free end of the flexible flat cable and align the solder points on the cable with the solder points on the circuit board B. The tweezers are then used to hold the flexible flat cable in place. With the other hand, an elastic pressure block is pressed against the top of the flexible flat cable to hold it down. The jig is then placed into a carrier and moved to the welding station for soldering. This manual method is prone to inaccurate and incorrect alignment. Furthermore, visually inspecting solder point alignment can lead to eye fatigue after prolonged operation, which can compromise quality. This solution provides an online automatic soldering device for flexible flat cables to address these issues. Utility Model Content
