[0023] Example:

[0024] like Figure 1-4 As shown, an automatic testing device for an RF chip testing machine according to the present invention includes a housing 1 and a testing module disposed within the housing 1. The housing 1 is a flat cuboid. A handle 2 is provided on one side of the housing 1. An opening is provided at one end of the length direction of the housing 1. A baffle 3 is fixed to the opening by screws. An opening 4 is provided at the other end of the housing 1. A mounting plate 5 is slidably connected inside the housing 1. The testing module is disposed on the mounting plate 5. A limiting mechanism is provided inside the housing 1 to prevent the mounting plate 5 from sliding.

[0025] Two baffles 6 extending along their length are provided on both sides of the inner side of the housing 1. The two baffles 6 form a slot for the mounting plate 5. The limiting mechanism includes a through hole 7 vertically disposed on the lower baffle 6. A limiting rod 8 is movably connected within the through hole 7. Both ends of the limiting rod 8 are rounded. The edge of the mounting plate 5 has a limiting hole. A push rod 9 parallel to the baffles 6 is movably disposed at the bottom of the inner side of the housing 1 via two guide sleeves 12 fixed to the inner wall of the housing 1. A push block 10 is provided on the push rod 9. The push block 10 has an upward-sloping surface 11 on the side near the opening. The bottom end of the limiting rod 8 abuts against the slope 11. The push rod 9 has a retaining ring 13 on the section between the two guide sleeves 12. A spring 14 is fitted on the push rod 9. The spring 14 is located between the retaining ring 13 and the inner guide sleeve 12. The spring 14 is in a compressed state. At this time, the bottom end of the limiting rod 8 is located at the top end of the slope 11. The top end of the limiting rod 8 passes through the limiting hole, thereby fixing the mounting plate 5.

[0026] The detection module includes:

[0027] The resource switching motherboard 15 integrates a USB power connector 16, a resource switching module, a resource switching device, and a test resource connector 17. The resource switching device adopts a multiplexed switching circuit and supports parallel testing of at least 8 independent test channels.

[0028] A power resource testing device is connected to the resource switching motherboard 15 and is used to test the current test board.

[0035] The detection module is housed within the housing 1, which is made of aluminum alloy to reduce overall weight while ensuring strength. A handle is provided on one side of the housing 1 for easy storage and carrying. By opening the cover and pushing the push rod 9 inward, the push block 10 is moved inward. The bottom end of the limiting rod 8 slides down the inclined surface 11, thereby driving the limiting rod 8 to descend. After the top end of the limiting rod 8 retracts into the through hole 7, the mounting plate 5 is pulled outward, thereby removing the detection module for easy maintenance of the equipment.

[0036] The usage process of this application is as follows: Connect the USB cable to the host via a wire; connect the test interface of the board under test to the resource connector 17 under test via a wire; open the automated test software on the host, select the test type and input the test parameters; start the test, the resource switching motherboard 15 activates the target test channels in sequence through the multiplexing switch circuit, the power self-test board collects voltage, current and impedance data and displays them in real time on the software interface, the RF power meter measures the signal strength and frequency with a dynamic range of not less than 30dB, the software compares with the preset threshold to determine whether the signal is drifting or abnormal, if a slight signal drift is detected (such as within ±0.5dB), the software automatically starts the calibration module to adjust the output parameters of the test board, if the drift exceeds the threshold or a fault is found (such as short circuit or signal loss), the software pauses the test and pops up a fault prompt box, indicating the location of the problematic board and the possible cause.

[0037] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
