[0038] Optionally, in the embodiment, the PCB automatic test equipment is provided with a rack 1, and an upper feeding station, a detection station, a sorting station and a lower feeding station are sequentially arranged along the extension direction of the rack 1. An upper end of the rack 1 is provided with a conveying device arranged along the extension direction of the rack 1, so that the product placed on the conveying device can be rotated between the upper feeding station, the detection station, the sorting station and the lower feeding station in sequence to sequentially perform the upper feeding process, the test process, the sorting process and the lower feeding process. The conveying device can be a belt wheel conveying device or a guide rail conveying device, which is not limited here. The lifting mechanism 2 is arranged at the upper feeding station, that is, the product is placed on the lifting mechanism 2 by manual operation, and the lifting mechanism 2 automatically lifts and moves the product into the device to perform subsequent operation steps. The test mechanism is arranged at the detection station, that is, the test mechanism is arranged adjacent to the lifting mechanism 2. The product is conveyed to the test station by the conveying device, the test mechanism tests the product, and the test data is sent to the sorting mechanism. The sorting mechanism is used to distinguish and classify the product quality, and the qualified and unqualified products are classified and processed. The product after sorting enters the lower feeding mechanism 9, and the automatic test and classification of the product are completed, which reduces the labor cost and improves the detection efficiency, and realizes the automatic test of the product.

The docking mechanism is used for processing and managing the PCB. In the whole manufacturing process, the docking machine plays a role of temporarily storing, transferring and protecting the PCB in the production line. It is usually composed of a conveying system, a transmission system and a control system. The conveying system is responsible for conveying the PCB, and uses special conveying belts, guide rails or swing arms to convey the PCB from one process to the next process to avoid the tediousness and potential damage risk caused by manual operation, and improve the production efficiency and product quality.

[0040] In the embodiment, the PCB automatic test equipment further comprises a screw mechanism 6, wherein the screw mechanism 6 is arranged adjacent to the first docking mechanism 51. The screw mechanism 6 comprises a screwing machine and a mechanical arm. The mechanical arm is drivingly connected to the screwing machine.

The PCB that passes through the ICT detection flows into the first sorting mechanism 41. If the product is qualified, it enters the next process. If the product does not meet the requirements, it is rejected or stays in the first sorting mechanism 41. When the PCB meets the ICT test, it enters the lower end of the burning mechanism 33. The burning mechanism 33 automatically burns programs to improve the production efficiency. After the burning program is completed, the product enters the second sorting mechanism 42 to test the PCB after burning. If it is qualified, it enters the FCT functional testing mechanism 32. The FCT functional testing mechanism 32 completes a series of product functional tests, such as LED module, audio module, IC burning, voltage measurement, communication test and the like, on the basis of the ICT, by supplying power to the to-be-tested PCB and matching the functional test module. After the FCT functional test is completed, the product enters the third sorting mechanism 43 to determine whether it is qualified. If it is qualified, it enters the next process.
