[0002] With the rapid development of science and technology, earphone and mobile phone and other electronic products play a more and more important role in people's life, and its function is constantly enriched and perfected, and wireless charging function has become one of the important characteristics of many such products. In order to ensure that the wireless charging function of the product is stable and reliable before it is put on the market, it needs to be strictly and accurately detected. A kind of test module of compatible multiple electronic product wireless charging function detection emerges as the times require, which aims to accurately position the position of wireless charging coil in the detection process through specific mechanical structure and technical means, and to ensure the good contact of charging head and product, so as to obtain accurate test data and avoid damage to the product.

[0003] In the existing wireless charging function detection technology, a relatively simple mechanical fixing device is usually used to fix the wireless charging coil and the product to be detected. For example, a fixed support is used to fix the wireless charging coil at a relatively fixed position, and then the earphone or mobile phone and other products are placed on a specific detection platform, and the product is moved to the position close to the wireless charging coil by mechanical arm or simple translation device, trying to align the two for charging function test. Its technical principle is mainly based on rough positioning of the product and the coil, relying on the basic stability of mechanical structure to maintain the relative position relationship in the detection process, and only some basic charging parameters such as whether the charging is successful or not are judged simply in the detection, lacking the fine control of the relative position accuracy of the coil and the product and the contact state.

[0004] However, the existing detection technology has obvious defects. Due to the lack of accurate position adjustment mechanism, it is difficult to ensure the accuracy of the center position of the wireless charging coil relative to the product, and there is often a large deviation, which can reach several millimeters or even more. This leads to that the wireless charging efficiency cannot be accurately measured in the test process, and the test data error is large. Moreover, without considering the flexibility of contact, when the charging head contacts the product, it is easy to appear bad contact due to improper pressure control, which affects the accuracy of test results, and also may cause scratches, wear and tear and other damage to the appearance of the product due to excessive pressure, seriously affecting the quality image and market competitiveness of the product, therefore a kind of test module of compatible multiple electronic product wireless charging function detection is proposed to solve the above problems.
