After the display device is manufactured, a process of inspecting an image by connecting a signal transmission cable to an image inspector is performed. In recent years, a display device and an image inspector are mainly connected using a flexible printed circuit board (FPCB). The FPCB is an electronic component developed by miniaturization and light weight of electronic products. It is excellent in workability, heat resistance, resistance to chemicals, and strong in heat, so it is a key component for connecting all electronic products such as cameras, computers, and peripherals. It is widely used in mobile communication terminals, video and audio equipment, camcorders, printers, DVDs, LCD monitors, satellite devices, and military equipment.

In the case of inspecting an image of a display device using a conventional image inspector, the FPCB is manually connected or a surface method applied with a urethane material is introduced, and the image signal is transmitted by simply pressing the cylinder from the top to form a contact point.

By the way, the conventional method of manually connecting the FPCB takes a long time, so the efficiency of inspection decreases, and the connection method that uses a face method and presses into the cylinder has a high possibility of non-contact, space constraints, and poor contact. There was a problem that the signal could not be delivered.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide an automatic connection device of a flexible printed circuit board which reduces contact error rate and connection time by using air and a slider.
