Description

Technical Field

[0001] This utility model relates to the field of product testing tooling technology, specifically a fixture for testing the pull-out force of metal parts in multiple locations on glass covers. Background Technology

[0002] In the consumer electronics and automotive electronics industries, the surfaces of products such as mobile phone cover glass often require the adhesion of multiple tiny metal components, such as nuts, positioning tabs, and shielding covers. The bonding reliability of these metal components is crucial to the overall performance of the product, therefore, pull-out force testing is necessary to verify their quality.

[0003] Currently, although existing testing methods can complete the testing, some problems still exist in practical operation: On the one hand, when using manual positioning for testing, the glass cover plate needs to be repeatedly disassembled and re-clamped each time a metal part is tested at a different location. Furthermore, a separate test reference point needs to be found for each metal part. However, this testing method is prone to positional deviations, causing the tension sensor to be out of axis with the metal part under test, generating lateral forces. This leads to inaccurate test data and may even damage the product or test probe. On the other hand, while fixture positioning currently available on the market can improve accuracy and testing efficiency to some extent, these fixtures are usually customized for a single product. Each measurement point requires a dedicated positioning fixture. This customization results in poor fixture versatility, making it unable to adapt to the needs of multi-sized product models or changes in the position of metal parts. This leads to low reusability, increased production costs, and increased testing difficulty.

[0004] Therefore, how to provide a universal fixture that can quickly and accurately locate and is applicable to pull-out force testing of metal parts at multiple different positions on a glass cover is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
