Description

Variable and automatic type film sagging tester}

The present invention relates to a film sagging tester, and more specifically, to a film sagging tester that includes a configuration that can manually or automatically change the position of a sagging detection member according to the operator's intention.

FCCL film, which is essential for information and communication device modules, is inspected for pin holes, scratches, dents, protrusions, foreign substances, compression, lifting, and discoloration during the production process, so defects cannot be identified with the naked eye during production and must be inspected under a microscope. This is an area that can only be inspected by magnifying it 10 times or more.

In addition, the inspection object of this inspection equipment has a film width of 500mm, so inspection is possible only with automatic inspection equipment.

A look at the prior art in this field is as follows. The first is a method of inspection using an area scan camera. This method requires inspection while the line is temporarily stopped, causing a delay in production time in the entire process, resulting in a significant decrease in product productivity and inspection time. There is also a problem that it takes a lot of time.

The second method is when only the dark field method is used. This method has the problem of detecting protrusions, dents, scratches, etc., but not detecting pin holes, foreign substances, discoloration, etc.

Conversely, when only the Light Field method is used, pin holes, etc. can be detected, but protrusions, dents, scratches, etc. cannot be detected. In the FCCL film inspection algorithm and surface defect inspection of the equipment, the present invention detects protrusions, dents, scratches, etc. using a dark field method, and detects pin holes, bubbles, black spots, etc. using a light field method.

The device shown in FIG. 1 was developed to solve this problem, but in the case of devices according to the prior art, each part constituting the device must be reassembled or reassembled to stably perform inspection in response to films having various widths or lengths. There is a problem that requires relocation.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
