[0002] The field of automated testing equipment has made significant progress in recent years, particularly in scenarios such as electronic product aging testing and batch product automated detection. With the continuous expansion of the electronic product market and the increasing demand for product quality from consumers, efficient and accurate aging testing is crucial for ensuring the performance and reliability of electronic products. This not only helps enterprises improve product quality and reduce after-sales costs, but also enhances their competitiveness in the market and promotes the healthy development of the entire electronics industry. At the same time, the progress of automated testing equipment also promotes the intelligentization and informatization of the production process, improving the efficiency and level of production management.

[0003] Currently, when performing aging testing on electronic products, the products are usually placed on a test table, and then the probes are controlled to contact the PIN points on the products for aging testing through manual or simple mechanical devices. The manual operation method mainly relies on the experience and skills of the operator, and the position of the probes is placed and controlled by visual observation. Simple mechanical devices generally achieve the contact between the probes and the products through pre-set programs or mechanical structures, such as using some simple transmission mechanisms and positioning components to assist in completing the operation.

[0004] However, the existing manual or semi-automatic testing equipment has obvious defects when performing aging testing. When the probes are inserted into the products, the positioning accuracy of the probes and the product PIN points is poor, and individual probes may deviate from the product PIN points, affecting the detection accuracy of the products. Moreover, the deviated probes may come into contact with other parts of the product, accelerating the wear of the probes and affecting the service life and testing cost of the testing equipment.

The product is carried by the same taking and placing method; when the discharging is completed, the product is carried by the same taking and placing method, 5 or 10 products can be picked up and transferred each time, so that the product testing process has high efficiency; 2. During testing, the test module of the upper detection module drives the needle template and the probe module to approach the carrier plate of the lower detection module. In the process of the needle template approaching the carrier plate, the positioning pin gradually inserts into the positioning bushing, and the carrier plate moves on the carrier and is preliminarily positioned by the floating spring of the needle template. Then, the positioning shaft and the positioning hole are inserted and matched to further position, and the floating block moves on the probe module to further guide and position the test probe by the floating block spring, so that the double floating positioning of the test probe is realized, and the detection accuracy of the product is improved. 3. The double floating positioning ensures that the test probe can be accurately aligned with the PIN point on the product, avoids the phenomenon that the probe deviates from the PIN point of the product, prevents the probe from being in contact with the rest of the product, and reduces the wear of the probe.
