Description

Technical Field

[0001] This invention relates to the field of automatic card slot detection technology, specifically to an automatic detection device for high-speed data transmission card slots. Background Technology

[0002] High-speed data card sockets are indispensable connecting components in electronic devices, widely used in various portable electronic devices such as mobile phones, tablets, and digital cameras. Their quality directly affects the stability of signal transmission and the overall performance of the device. With the rapid development of 5G communication technology and high-speed data transmission protocols, the transmission rate of data card sockets is constantly increasing, and the requirements for their manufacturing precision and electrical performance are becoming increasingly stringent. Therefore, each data card socket must undergo rigorous electrical performance testing before leaving the factory.

[0003] Currently, traditional data card slot inspection mainly relies on manual operation or semi-automated single-station inspection equipment. Manual inspection typically involves operators manually placing the card slot to be tested into the inspection fixture, starting the inspection instrument to complete the test, and then manually removing and sorting it. This method is not only labor-intensive and inefficient, but the manual loading and unloading process can also easily scratch or contaminate the card slot, affecting the accuracy of the test results and making it difficult to meet the needs of large-scale production.

[0004] While existing semi-automated testing equipment reduces manual intervention to some extent, it still has many shortcomings. First, these devices typically use a single loading or unloading mechanism, resulting in discontinuous material flow. Manual assistance is still required during loading and unloading, preventing true full-process automation. Second, the control logic of existing equipment is mostly based on fixed parameters, failing to dynamically adjust operating parameters according to real-time changes in operating conditions. When the operating environment changes or prolonged operation leads to component wear, problems such as decreased positioning accuracy, unstable clamping force, and drifting detection signals can easily occur, affecting detection accuracy and consistency. Furthermore, existing equipment lacks effective coordinated control between functional modules, resulting in loose timing of actions, interference, or delays, reducing overall equipment operating efficiency.

[0005] To address the aforementioned issues, it is necessary to develop a high-speed data card slot automatic testing device capable of achieving fully automated testing throughout the entire process and possessing high-precision dynamic control capabilities. This would improve testing efficiency and accuracy, meeting the modern electronics manufacturing industry's demand for high-quality and high-efficiency production. Summary of the Invention

(Related to the stability of base 1; the more securely base 1 is fixed, the better.) The smaller the value (based on the test calibration of this equipment), the higher the real-time load rate of the drive components.
