Description

Reinforcement inspection tooling for flexible circuit board

technical field

The utility model relates to the field of manufacturing of flexible circuit boards, in particular to an inspection tool.

Background technique

The flexible circuit board (FPC) is characterized by light, thin, short and low mechanical strength, so it is prone to cracks, folds, scars and other undesirable phenomena during use. For this reason, reinforcing materials are usually attached to the FPC to strengthen it. Mechanical strength, and at the same time, it is convenient to mount other parts. At present, there are three common bonding methods for reinforcing materials in the industry: single-piece tooling bonding, strip bonding, and machine bonding. The above three processes all have the risk of repeated bonding, and because the reinforcing It is difficult to discriminate by the way of the board, therefore, there is an urgent need for an inspection tool with simple operation and high efficiency.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a reinforcement inspection tool for flexible circuit boards, which can quickly inspect whether there is repeated mounting on the circuit board, is easy to use, simple to operate, and will not damage the circuit board during the inspection process. The circuit board does not cause damage, the structure is simple, and it is easy to be practical.

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

A reinforcing inspection tool for a flexible circuit board, including a base plate, a limit device, a guide column and an adjustment screw, the base plate includes a horizontal reference plane on which a guide column is fixed, the limit device is arranged above the reference plane, and An inspection gap is formed between the reference plane and the guide hole corresponding to the guide post on the limit device. The limit device can move up and down relative to the substrate through the guide post and the guide hole to adjust the size of the inspection gap. The limit device and the substrate A vertical threaded hole is arranged on the top, and the adjusting screw is screwed into the threaded hole on the base plate after passing through the threaded hole on the limit device.

As a further improvement of the above solution, the limiting device is a cylinder, and the axis of the cylinder is parallel to the reference plane.

As a further improvement of the above solution, the size of the inspection gap is slightly larger than the thickness of the flexible circuit board bonded with a single-layer reinforcing material, and smaller than the thickness of the flexible circuit board bonded with a double-layer reinforcing material.

The beneficial effects of the utility model are:

It can quickly check whether there is a phenomenon of repeated mounting on the circuit board, is convenient to use, simple to operate, does not cause damage to the circuit board during the inspection process, and has a simple structure and is easy to use.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

detailed description

The conception, specific structure and technical effects of the utility model will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, scheme and effect of the utility model. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

It should be noted that, unless otherwise specified, when a feature is called "fixed" or "connected" to another feature, it can be directly fixed and connected to another feature, or indirectly fixed and connected to another feature. on a feature. In addition, the descriptions such as up, down, left, and right used in the utility model are only relative to the mutual positional relationship of the various components of the utility model in the drawings.

Also, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terms used in the specification herein are for describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any combination of one or more of the associated listed items.

Referring to FIG. 1 , a schematic diagram of an embodiment of the present invention is shown, including a base plate 1 , a limiting device 2 , a guide column 3 and an adjusting screw 4 .

As a supporting structure, the base plate 1 has a horizontal reference plane on which guide posts 3 are fixed. Preferably, there are two guide posts 3 .

The limit device 2 is arranged above the reference plane and forms a check gap with the reference plane. A guide hole 21 is provided on the limit device 2 corresponding to the guide column 3, and the guide column 3 is inserted into the guide hole 21, so that the limit device can move up and down relative to the substrate 1 through the guide column 3 and the guide hole 21, thereby adjusting the inspection gap the size of.

In addition, the limiting device 2 and the base plate 1 are provided with vertical threaded holes, and the adjusting screw 4 is screwed into the threaded hole on the base plate 1 after passing through the threaded hole on the limiting device 2. In this way, as the adjusting screw 4 is screwed in or unscrewed, which can drive the stopper 2 to move up and down.

Referring to Fig. 2, the usage method of the utility model is as follows: first, turn the screw to move the limiting device upwards, place the flexible circuit board 5 with a single layer of reinforcing material as a reference plate between the limiting device and the substrate, and then Rotate the adjusting screw in the opposite direction to press down the limit device until it just touches the flexible circuit board. At this time, the size of the inspection gap is just enough to allow the single-layer reinforced flexible circuit board to pass through, while the double-layer or multi-layer circuit board will pass through. Blocked, so that you can check whether there is a phenomenon of multi-layer bonding of the circuit board.

Preferably, in order to prevent the limit device from scratching the circuit board, the size of the inspection gap should be slightly larger than the thickness of the flexible circuit board bonded with a single-layer reinforcing material, but smaller than the thickness of the flexible circuit board bonded with a double-layer reinforcing material. thickness. In actual use, when the adjusting device just touches the flexible circuit board, it is necessary to reversely turn the adjusting screw half a turn, so that the size of the gap is slightly larger than the thickness of the circuit board.

Further, the limiting device 2 is preferably in line contact with the circuit board. In this embodiment, the limiting device 2 adopts a cylinder whose axis is parallel to the reference plane, so that the number of limiting devices can be reduced. 2 The contact area with the circuit board can effectively reduce the possibility of scratches.

The above is a specific description of the preferred implementation of the present utility model, but the invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent deformations without violating the spirit of the present utility model Or replacement, these equivalent modifications or replacements are all included within the scope defined by the claims of the present application.
