[0002] During the production of mobile phones, in order to verify whether a mobile phone supports the OTG (On-The-Go) function, it is necessary to conduct OTG tests on the mobile phone. The test steps are generally to insert an OTG adapter into the USB interface of the mobile phone, check whether the mobile phone can recognize the connected USB device and check whether a USB flash drive or other devices can be found in the file manager of the mobile phone, attempt to transfer files from the USB device to the mobile phone and then attempt to transfer files from the mobile phone to the USB device, such as files in different formats (such as pictures, videos, documents, etc.). Through the above process, the connection, recognition, data transfer, power supply, compatibility, and stability of the mobile phone are tested. Therefore, it is necessary to conduct upgrade tests on mobile phones before leaving the factory.

There is no need to replace the test fixture 3 when switching different mobile phone models. It has strong versatility and can also reduce equipment failures.

[0031] In addition, the surface material of the product positioning plate 34 is bakelite (coated with Teflon). Bakelite, also known as phenolic plastic, is a commonly used insulating material. Coating Teflon (PTFE) on the surface of bakelite can further enhance the insulating performance of bakelite, making it difficult for other substances to adhere to the surface of the product positioning plate 34 and facilitating cleaning.

[0033] The test control principle is roughly as follows: By inputting the mobile phone model into the device software, the corresponding flashing package can be downloaded from the server to the local computer. Then, after formatting the data in the USB flash drive by selecting the USB flash drive, the new flashing package is written into the USB flash drive. After the writing is completed, the software internally verifies the names of the flashing packages in the USB flash drive and the server. After that, the USB flash drive is encapsulated to prevent manual access to the internal files of the USB flash drive for rewriting. The USB flash drive replacement record can generate a log for monitoring.

[0034] Preferably, in order to provide additional boosting force to the mobile phone on the test fixture 2, the auxiliary lifting member 39 includes an auxiliary support block 391, an auxiliary roller 392, a roller swing arm 393, and an elastic protrusion 394.

[0041] The working principle of the present utility model is as follows:

[0042] First, the mobile phone is fed through the feeding conveyor line. When it flows into the product grasping position of the pick-and-place manipulator, the upper vision detection device performs upper CCD photographing detection (with anti-fooling function) on the mobile phone at this position. After the vision detection is completed, the handling and moving mechanism drives the pick-and-place manipulator to grasp the mobile phone and then send the mobile phone to the test fixture on the fixture mounting plate in sequence. After the test fixture clamps the mobile phone, it is inserted into the device transmission line for upgrade testing. After the testing is completed, the pick-and-place manipulator moves the tested mobile phone to the gap portion of the feeding conveyor line for lower CCD photographing vision detection. The mobile phone that passes the detection is directly placed on the discharging conveyor line by the pick-and-place manipulator and output to the next production station, and the mobile phone that fails the detection is placed at the product grasping and discharging position of the feeding conveyor line, and is transferred to the defective product conveyor line for temporary storage by the clamping and transferring mechanism, and finally collected by the tester.

[0043] The mobile phone upgrade testing process is as follows: Insert the device transmission line into the mobile phone USB through the test fixture, check the communication between the USB flash drive of the OTG control board and the mobile phone, perform reverse voltage detection and CC pin monitoring (if the communication is abnormal, put the mobile phone on the defective product conveyor line). If the connection is normal, the OTG control board switches to the OTG mode, and then starts OTA upgrade for the mobile phone. After the OTA is completed, the mobile phone automatically restarts, and the control board performs reverse voltage detection and CC pin monitoring. After monitoring that the mobile phone restarts, the OTG control board switches to the USB mode, and the PC attempts to obtain the boot port of the mobile phone (if the acquisition fails, put the mobile phone on the defective product conveyor line). If the acquisition is successful, the USB is unplugged and the mobile phone is placed on the discharging conveyor line for discharging.
