Description

A double-station FPC inspection fixture

technical field

The utility model relates to an FPC detection fixture, in particular to a double-station FPC detection fixture.

Background technique

Flexible circuit board, referred to as FPC, is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film, with high wiring density, light weight, and thickness Thin features. Has been widely used in mobile phones, notebook computers, PDAs, digital cameras, LCM and other products.

In the production process of flexible circuit boards, after the FPC is punched, it is usually necessary to inspect the FPC, and it usually takes 10-15 seconds to inspect each FPC. The current FPC testing fixture usually only installs one station, and after testing an FPC, it takes 5-8 seconds for the operator to remove the tested FPC and place the FPC to be tested, that is, the equipment is idle during this period state. At the same time, when the FPC testing fixture is testing, the operator can only wait by the side. Based on the above reasons, it can be seen that the working efficiency of the current FPC inspection fixture is low, and there is a large room for improvement. In addition, if one person operates multiple machines, the space occupied between settings will be obviously large, and the operation will be inconvenient.

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides a double-station PFC detection fixture with higher production efficiency, compact structure and convenient operation.

The technical scheme that the utility model solves its technical problem adopts is:

A double-station FPC detection fixture, including a support, two identical supports are symmetrically arranged above the support, and two lower die installation grooves for installing the lower die are provided; the center of the top of the support There is a vertically installed air pump and two vertical guide holes for installing the guide column; the air pressure rod of the air pump and the lower part of the guide column are connected with the upper mold mounting block for installing the upper mold.

As an improvement of the above technical solution, a lower mold protection plate is provided between the lower mold installation groove and the lower mold; an upper mold protection plate is provided between the upper mold installation block and the upper mold.

The beneficial effects of the utility model are: the utility model improves the working efficiency obviously by improving the common single-station FPC detection jig into a double-station FPC detection jig, and at the same time the jig is compact in structure and easy to operate .

Detailed ways

Referring to Fig. 1-Fig. 6, a double-station FPC detection fixture includes a support 1, two identical supports 2 are arranged symmetrically above the support 1, and two are used to install the lower mold 3 The lower mold installation groove 11 of the lower mold; the center of the top of the support 2 is provided with a vertically installed air pump 21 and two vertical guide holes 23 for installing the guide column 22; the air pressure rod 211 of the air pump 21 and The lower part of the guide post 22 is connected with the upper die mounting block 24 for installing the upper die 4 .

The specific operation of the above-mentioned double-station FPC detection fixture is as follows: first, turn on the power, place the FPC to be tested in one of the stations, press the corresponding down button 12 with both hands, and the FPC detection fixture will perform detection for 10-15 seconds ;In the detection interval, the operator can place the FPC to be tested at another station, and press the corresponding down button 12 with both hands after placing it; For the FPC, both hands press the corresponding pressing key 12, and the operation is repeated like this. Its characteristic is that when one station is testing, another station is taking out the tested FPC and placing the tested FPC. Therefore, during the whole day's inspection process, the two stations of the inspection fixture are always working, so the efficiency is significantly higher than that of the single-station FPC inspection fixture.

As an improvement of the above technical solution, a lower mold protection plate 5 is provided between the lower mold installation groove 11 and the lower mold 3 ; an upper mold protection plate 6 is provided between the upper mold installation block 24 and the upper mold 4 . After the detection jig has been used for a period of time, only the lower mold protection plate 5 or the upper mold protection plate 6 needs to be replaced to prevent the detection jig from decreasing in accuracy due to long-term use.

Of course, in addition to the above-mentioned implementation modes, other equivalent technical solutions of the utility model should also be within the protection scope thereof.
