Background

Along with the fact that electronic products such as mobile phones and flat panels are smaller and smaller in spatial structure and higher in integration of assembled devices, the requirement for manufacturing high-precision FPCs is more urgent, and the size control capability of FPC boards is gradually strict. At present, the common practice in the FPC industry is to punch a positioning hole of a cake by using an automatic punching machine to improve the positioning accuracy, and the principle is to identify a mark point of a target hole by using a CCD, and then to perform punching after compensating an appropriate amount by system software according to an offset value. Thus, the operation of the apparatus relies on identifying circular mark points within each target hole.

However, when the mark point has defects, surface foreign matters, inconsistent sizes and other abnormal conditions, the equipment can misjudge the 'position needing punching' as 'the hole position not needing punching'; thereby causing hole leakage and punching. The missed punching can directly result in the current plate being scrapped due to the fact that the plate cannot be used in the post-processing process, and once the hole position needed to be used in an assembly factory is missed punching, the electrical performance of a finished product can be poor.

SUMMERY OF THE UTILITY MODEL

Therefore, an object of the utility model is to provide a leak FPC and detection device towards locating hole based on open circuit test control to solve traditional FPC and easily appear leaking the problem towards the target hole.

The utility model provides a FPC based on open circuit test control leaks and dashes locating hole which characterized in that: the plate comprises a body part and a plate edge part arranged on the outer side of the body part, wherein a plurality of pre-punching positioning hole positions are arranged on the plate edge part, a target point is arranged at the center of each pre-punching positioning hole point, and the target points are made of conductive materials.

Furthermore, the target point is made of copper, and the target point is solid round copper.

The FPC detection device is used for detecting whether a missed punching hole exists in the FPC or not, the FPC comprises a body portion and a plate edge portion arranged on the outer side of the body portion, a plurality of pre-punching positioning hole positions are arranged on the plate edge portion, a target point is arranged in the center of each pre-punching positioning hole point, and the target points are made of conducting materials. The FPC detection device based on open circuit test monitoring is leaked and is punched locating hole includes two electric circuit test needles, two electric circuit tests and detects to same target point.

The testing device comprises a rack, and a positioning device and a testing device which are arranged on the rack, wherein the positioning device and the testing device are arranged in a vertically opposite mode; the testing device is provided with a plurality of detection positions, and each detection position is provided with two electric loop testing needles.

The device further comprises a display screen and an alarm device, wherein the information detected by the testing device is displayed on the display screen, and the alarm device gives an alarm to an abnormal result.

Furthermore, an identification device is further arranged, the identification device can identify the FPC with abnormal detection results and identify the position of the missed punching hole.

To sum up, the utility model discloses a set up the target spot that has the conduction function and set up the test to the target spot carry out the electric open, short circuit test to realized that automatic control leaks to dash the locating hole, cooperate the automatic bad board identification point of breaking up of test machine, and then can be high-efficient, zero leak ground block leak punch a hole defective products, promoted production efficiency greatly. The utility model discloses a practicality is strong, has stronger popularization meaning.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

As shown in fig. 1 and 2, the utility model provides a FPC based on open circuit test control leaks and dashes locating hole, FPC based on accurate measuring of laser cutting accuse deep groove includes this portion 10 and sets up in the flange portion 20 in this portion 10 outside, be provided with a plurality of location hole sites of dashing in advance on the board portion 20, the central point that each dashes the locating hole point in advance puts and is equipped with a target point 30, target point 30 is made by conducting material. In this embodiment, the target 30 is made of copper, and the target 30 is a solid circular copper PAD.

The FPC anti-collision positioning target hole detection device comprises a rack (not shown), a positioning device (not shown) arranged on the rack, a testing device 40 and a display screen (not shown), wherein the positioning device is used for positioning the FPC and can be arranged vertically and oppositely to the testing device 40. The testing device 40 is provided with a plurality of detection positions, and each detection position is provided with two electric loop testing needles 41. In addition, still be provided with an identification means on the detection device, identification means can carry out the sign to the FPC that detects NG to the hole site is marked out with obvious sign to the hourglass is dashed, so that follow-up rework repair.

When the FPC testing device is used, the FPC is arranged in the positioning device, the plurality of testing positions on the testing device 40 are used for testing the corresponding target points 30, the two electric loop testing needles 41 on each testing position extend downwards to the same target point 30 for testing, and if the two electric contact points form a short circuit, the target point 30 is not washed away, and the target point is a washing-missing position.
