Quick test fixture of smart card angularity

Technical Field

The utility model relates to a test in the smart card manufacturing is with frock especially discloses a smart card angularity tests frock fast, mainly is applied to smart IC card and makes the field, can carry out quick examination to the smart card, qualitatively measures the angularity of smart card rapidly.

Background

The prior art generally adopts a test method for the warping degree index of the smart card as part 1 of a GB/T17554.1-2006 identification card test method: general characterization Test Identification cards-Test methods-Part 1. General characteristics tests (ISO/IEC 10373-1:1998, MOD.) as the basis of the directional measurement approach. The reference of the measuring method is the national standard in 2006, the main raw material for manufacturing the card is only PVC material, and the possibility of the intelligent card obtained by manufacturing the same material to warp unevenly is extremely low, so that the requirement of actual production can be completely met by adopting a sampling and quantitative measuring method.

However, since 2009, with the expansion of the application field of smart cards, the large-scale investment of PET materials into various types of smart cards such as traffic cards and subway tickets, and the phenomenon of card warping in the manufacture of smart cards has become a common industrial problem in the industry. Particularly, most of the current PET smart cards are composite structures formed by compounding a PET layer with a PVC layer, the PET refers to Polyethylene terephthalate (PET), the chemical formula of which is COC6H4COOCH2CH2O, and the english term of which is Polyethylene terephthalate (PET), and the material has a characteristic of being biaxially oriented and must be used in pairs, otherwise, the material is warped. This is a product design inherent deficiency. The product defect caused by the inherent defect of the raw material selected during the product design is a suboptimal solution for solving the problem that the card body is easy to break and break under special conditions. The compound smart card preparation that the compound PVC layer on PET layer is constituteed requires same card must use same a pair of PET material, can guarantee that this kind of compound card is not warping, so this kind of PET layer and PVC layer composite bed smart card easily appear the warpage phenomenon, this just makes traditional warpage test method lose the place of use that should have, the means that original ration combines the spot check has been difficult to manage and control smart card manufacturing process control, cause the card to have warpage problem and defective products outflow risk.

The existing test means of the warping degree index of the smart card at present is to project the side face of the smart card by using a 3D or 2.5D projection device, perform projection test by using two-dimensional measurement software carried by the device (see the attached figure 1: a working principle schematic diagram of a warping degree measurement projection instrument for measuring the warping degree of the smart card), and compare the measured data with a standard to judge whether the warping degree of a to-be-measured piece meets the standard. The actual requirements of the current industrial mass production cannot be met by the testing means, so that a testing method or a testing instrument for rapidly screening warpage is urgently needed.
