Description

Technical Field

[0001] This utility model relates to the field of assembly machine technology, specifically to an automatic assembly machine for main FPC cables. Background Technology

[0002] FPC (Flexible Printed Circuit) cables are a type of connecting wire assembly that can be bent to a certain extent. They are mainly used in industrial products. FPC cables are usually made of one or more flexible substrates. By embedding conductive copper foil and circuit layers, flexible circuit channels are formed. This design allows the FPC cable to be bent and folded within a certain range without damage. Therefore, compared with traditional rigid printed circuit boards, it has better flexibility and durability. With the upgrading of mobile phone assembly products, it is necessary to improve product stability and yield as soon as possible. Internal human resources are tight and costs are high. There is an urgent need to replace human labor with equipment. Therefore, an automatic assembly machine for main FPC cables is proposed.

[0003] For example, an FPC assembly line device disclosed in the authorization announcement number CN209647831U includes a workbench, a base box, and a connecting frame. The base box is located at the bottom of the workbench. The connecting frame is fixedly connected to the upper part of the workbench. Limiting block one, a spot welding station, and limiting block two are installed on the upper part of the workbench. Limiting block one is provided on one side of the spot welding station, and limiting block two is provided on the other side of the spot welding station. An FPC board is snapped onto the upper part of limiting block one. A proximity switch is installed on the upper side inside the spot welding station. An electric wire is snapped onto the upper part of limiting block two.

[0004] Although it achieves efficient welding and assembly between FPC boards and wires by setting up spot welding machines, electric cylinders and fixing clamps, which facilitates the completion of FPC board assembly line work, by setting up chains and gear disks, it is easy for moving blocks to move on the upper part of the connecting frame, thereby adjusting the position of spot welding machines. By setting up cooling fans, it effectively and quickly cools down the welding point between the FPC board end and the wire end, avoiding the spot welding temperature from being too high and affecting the conduction of the line electricity.

[0005] However, it does not solve the problem that existing assembly machines are not conducive to conveniently adjusting and adapting to FPC cables of different lengths, nor to classifying and outputting FPC cable boards. They are also not conducive to inputting FPC cables of different lengths and to quickly crimping FPC cables, which affects the convenience of FPC cable input and the flexibility of output.
