Description
Technical Field
[0001] This utility model relates to the field of chip test fixture technology, and in particular to a 5G chip radio frequency test fixture. Background Technology
[0002] Test fixtures are crucial equipment in the 5G chip manufacturing process. Currently, when performing 5G RF testing, workers need to manually place the product into the fixture and manually scan the barcode using a barcode scanner. However, regardless of whether the 5G chip is completely flat within the mounting space, the fixture will forcibly close for testing, easily causing improperly placed products to be damaged by the fixture mechanism. Furthermore, after testing, the fixture needs to be manually opened to confirm and upload the results to the server. This process suffers from high scrap rates and low efficiency; therefore, one-click automation of these steps is essential. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figure 1-2 The embodiments of this utility model include:
[0022] A 5G chip radio frequency testing fixture includes the following components: a test base 1, a first start button 2, a second start button 3, an emergency stop button 4, a flatness sensor 5, a contour positioning groove 6, a translation guide rail 7, a translation cylinder 8, a translation frame 9, a pressure head 10, a pressure head cylinder 11, a code reading assembly, and a controller 12.
[0023] The test base has a first start button and a second start button on its top surface, an emergency stop button on its side, a contour positioning groove on its side for positioning the chip under test, and a flatness sensor for detecting whether the chip is placed flat and a probe for connecting to the electronic components on the chip on its bottom surface.
[0024] The translation guide rail is set on the test base, the translation frame is slidably connected to the translation guide rail, the output end of the translation cylinder is connected to the translation frame to drive the translation frame to move back and forth along the translation guide rail, the pressure head cylinder is set on the translation frame, and its output end is connected to the pressure head to drive the pressure head to move up and down, thereby pressing and fixing the chip in the contour positioning groove.
[0025] The pressure head and the translation frame are movably connected by the lifting guide shaft 14 and the bushing to improve the accuracy of lifting.
[0026] The controller is connected to the first start button, the second start button, the emergency stop button, the flatness sensor, the translation cylinder, the pressure head cylinder, and the code reading component. The controller can exchange data with the central control computer or server via wired or wireless means to facilitate the storage of information data.
[0027] The controller includes a PLC120, a power input interface 121, a gas input interface 122, a radio frequency instrument input / output interface 123, and a computer connection interface 124.
[0028] The barcode reading assembly includes a visual barcode reader 131, a fixed stand 132, an adjusting bracket 133, a rotating shaft 134, a limiting groove 135, and a locking bolt 136.
[0029] The fixed bracket is set on the test base, and the adjustable bracket is movably set on the fixed stand to adjust its height. The visual barcode reader is rotatably connected to the adjustable bracket via a rotating shaft. The adjustable bracket is also provided with an arc-shaped limiting groove. One end of the locking bolt passes through the limiting groove and is detachably connected to the visual barcode reader to lock the angle of the visual barcode reader.
[0030] During testing, first connect the power input interface of the fixture to power it on, connect the gas input interface to allow gas to flow, connect the RF instrument input / output interface to connect the RF testing instrument, and connect the computer and server via the computer connection interface. The programmable logic controller (PLC) controls the fixture's logic. Then, after ensuring the emergency stop button is in the correct position, place the 5G chip into the contour positioning slot. Both hands must simultaneously press the first and second start buttons to prevent accidental hand injuries from the fixture. A flatness sensor automatically determines whether the 5G chip is placed flat in the contour positioning slot; if the flatness requirement is not met, the device cannot be shut down. During fixture testing, if the flatness requirement is met, the side vision barcode reader will read the serial number of the 5G chip. The translation cylinder will then move along the right and left translation rails, bringing the pressure head and pressure head cylinder above the contour positioning slot. The pressure head cylinder will then press down, ensuring the pressure head is in contact with the 5G chip in the contour positioning slot, maintaining tight contact between the 5G chip, its lower surface, and the test probe. The central control computer will then begin automatic testing. Once the test is complete, the pressure head cylinder will lift up, retracting the pressure head. The translation cylinder will then reset and move away, exposing the 5G chip in the contour positioning slot. Simultaneously, the computer will upload the 5G chip's serial number and the test results to the server, and personnel will then remove the tested 5G chip.
