Description

Technical Field

[0001] The utility model relates to a field, and in particular to a hot pressing device for producing flexible flat cables. Background Art

[0002] The hot pressing equipment used in the production of flexible flat cables is mainly used to make and process flexible circuit connectors, especially in the process of manufacturing flexible flat cables (FFC) or flexible printed circuits (FPC).

[0003] A hot pressing device provided according to patent application number CN201610364546.4 includes a base, an external frame, a positioning block, a downward pressure cylinder, a ejector pin and a hot pressing plate. The hot pressing device has a simple structure, low cost, and can improve the efficiency of hot pressing processing.

[0004] The shortcomings of the above-mentioned device are: during use, the entire device lacks a pressing machine assembly, so the flexible wire and the component to be hot-pressed and connected are easily displaced due to the vibration of the device, resulting in a loose connection or even a wrong connection, which in turn causes an increase in the defective rate of the product after hot pressing. During use, the hot pressing assembly of the entire device is located above the hot pressing area. Since the flexible wire needs to be manually placed in the hot pressing area, it is easy for personnel to get burned during operation, or improper operation may cause the hot pressing assembly to be pressed down, resulting in the hand being pinched, which makes its use unsafe.
