Description

Technical Field

[0001] The present disclosure relates to the field of power amplifier testing, and in particular to a power amplifier automatic aging test method and system. Background Art

[0002] Power amplifier products are often diverse, encompassing a wide variety of professional and IP-based amplifiers, with power levels ranging from a few hundred watts to several thousand watts. Different models require distinct aging test protocols. Traditional amplifier aging testing relies primarily on manual operations, including wiring, product placement, parameter configuration, and data recording. This approach is inefficient, prone to errors, and unable to monitor various parameters during the aging process in real time. Amplifier aging testing requires specific environmental conditions, such as a stable power supply, appropriate temperature, and humidity. Traditional manual methods struggle to ensure the stability and consistency of these conditions.

[0003] Existing aging test technology has limitations. First, the degree of automation is low and manual operation is cumbersome: Traditional aging tests require manual handling, wiring, and placement of products, which is not only inefficient but also prone to operational errors due to human factors. Second, inaccurate data recording: Manual recording of aging data is prone to omissions and errors, and the accuracy and completeness of the data cannot be guaranteed. Third, insufficient monitoring capabilities: Traditional aging test systems lack real-time monitoring functions and cannot promptly detect problems that arise during the aging process. Fourth, incomplete data storage: The storage method for aging data is relatively simple and lacks systematic management and analysis functions. Fifth, poor compatibility and difficulty in adapting to different models: Existing aging test systems are mostly designed for a single model or a few models, and it is difficult to adapt to the testing needs of multiple models of power amplifiers. Sixth, insufficient scalability: The system is difficult to expand and upgrade according to new testing requirements. Summary of the Invention

[0004] The present disclosure provides a method and system for automatic aging testing of power amplifiers to solve the problems existing in related technologies. The technical solutions are as follows:

[0005] In a first aspect, an embodiment of the present disclosure provides a method for automatic aging testing of a power amplifier, comprising the following steps:

[0006] Classify according to the type of power amplifier, wherein the type of the power amplifier is determined by the product information QR code affixed to the power amplifier in advance;

[0007] Scan the QR code to determine the aging line and the position information in the aging line; wherein there are multiple aging lines, each aging line is suitable for aging tests of different power amplifier types and has multiple positions to accommodate multiple power amplifiers;

[0008] After determining the position information, the power amplifier is transported to the corresponding position, lifted, contacted and powered on for testing;

[0009] Monitor the aging data and time the power amplifier under power-on test until the aging is completed and the aging results are displayed.

[0010] Optionally, categorize by amplifier type, including:

[0011] The QR code is generated based on the product name, type, serial number, designated aging bit and aging type.

[0012] Optionally, before scanning the QR code to determine the aging line, it also includes: scanning the QR code to determine whether it is normal aging. If it is normal aging, manual wiring is performed and the product is placed at the loading position; if it is not normal aging, the power amplifier is released without wiring; if it is a traditional aging product, the product is unloaded for traditional aging testing.

[0013] Optionally, scanning the QR code to determine the aging line includes: scanning the code at the loading position to determine whether aging is required. If aging is required, determining whether aging is required in the current aging cabinet. If not, unloading or transporting forward.

[0014] Optionally, after determining the storage location information, the power amplifier is transported to the corresponding storage location for lifting, contacting, and power-on testing, including:

[0015] The power amplifier is transferred to the aging rack. If the position information matches the ID of the aging rack, the power amplifier is transported to the corresponding position on the aging rack. If the position information does not match the ID of the aging rack, the power amplifier is transferred to other aging racks until it matches the ID of the aging rack and the corresponding position is found, or if there is no match after transferring to all aging racks, the power amplifier that has passed the station is transported out for retuning.

[0016] Optionally, transporting the power amplifier to a corresponding position on the aging rack includes:

[0017] carrying the power amplifier to a hoist;

[0018] The hoist distributes the amplifiers to corresponding locations, wherein the location definition rules are: workshop, aging line corresponding to the aging rack, layer of the aging line, and location corresponding to each layer.

[0019] Optionally, lift contact power-up test, including:

[0020] After the power amplifier is in place, the power amplifier is lifted up and powered on.

[0021] Optionally, after the aging is completed and the aging result is displayed, the following steps may be further included:

[0022] The hoist transports the power amplifier to the unloading position;

[0023] Unloading the power amplifier from the discharge position to the transfer line and then to the retuning line;

[0024] Transporting the amplifier to a retuning station on a retuning line, and scanning a code at the retuning station to obtain an aging result of the power amplifier;

[0025] Determine whether to cut or re-adjust based on the aging results.

[0026] In a second aspect, the present disclosure also provides an automatic aging test system for a power amplifier, comprising:

[0027] A code sticking station is used to stick a QR code to the power amplifier, wherein the QR code is generated according to the product name, type, serial number, designated aging position and aging type;

[0028] At the loading station, the amplifiers transferred from the coding station are scanned and classified for different types of aging. If the aging is normal, the power amplifiers are manually wired and placed at the loading station. If the aging is not normal, the power amplifiers are released without wiring. If the aging is traditional, the products are unloaded for traditional aging testing.

[0029] The aging rack selects a station, and the amplifier after manual wiring is transferred to the aging line and matched with different aging rack IDs. If a match is found, the corresponding position is searched. If the IDs of all aging racks do not match after all stations are transferred, the amplifier that has passed the station is transported out for retuning.

[0030] The power-on station is lifted up to conduct power-on testing on the power amplifiers that have arrived at the corresponding positions. The aging data of the power amplifiers undergoing power-on testing is monitored and timed until the aging is completed and the aging results are displayed.

[0031] Optionally, a retuning station is further included for obtaining product aging information of the power amplifier after aging and the power amplifier that needs to be retuned in passing stations to determine whether to unload or return to the loading position for retuning.

[0033] This disclosure classifies the amplifiers and then scans the code to determine the aging method. It can also automatically select the available slots for different aging methods based on the amplifier type, improving the degree of automation and allowing different types of amplifiers to be tested synchronously within the same aging system.

[0034] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present disclosure will be readily apparent by reference to the accompanying drawings and the following detailed description.

[0038] Figure 3 2 is a framework diagram of the automatic aging test system for power amplifiers in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0039] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0040] The present disclosure provides a method for automatic aging test of a power amplifier. Figure 1 As shown, the following steps are included:

[0041] S10, classifying according to power amplifier type, wherein the type of the power amplifier is determined by a QR code previously attached to the power amplifier;

[0042] S20. Scan the QR code to determine the aging line and the position information in the aging line; wherein there are multiple aging lines, each aging line is suitable for aging tests of different power amplifier types and has multiple positions to accommodate multiple power amplifiers;

[0043] S30, after determining the storage location information, transporting the power amplifier to the corresponding storage location, lifting the contacts, and conducting a power-on test;

[0044] S40: Monitor aging data and perform timing on the power amplifier undergoing power-on test until aging is completed and the aging result is displayed.

[0045] As an optional implementation, the power amplifiers are classified according to their types, including:

[0046] The two-dimensional code is generated according to the product name, type, serial number, designated aging position and aging type. The generated two-dimensional code has the information of the power amplifier to be aged, so as to facilitate the subsequent classification aging test.

[0047] As an optional implementation, before scanning the QR code to determine the aging line, the following steps are also included: scanning the QR code to determine whether it is normal aging. If it is normal aging, manual wiring is performed and the product is placed at the loading position; if it is not normal aging, the power amplifier is released without wiring; if it is a traditional aging product, the product is unloaded for traditional aging testing. Among them, the embodiment of the present disclosure has multiple aging options. Some customized products are not suitable for testing on the aging line, that is, they are not suitable for normal aging, or the test equipment does not include the test conditions for the corresponding products. Such customized products also need to be sorted out for manual testing.

[0048] As an optional implementation, scanning the QR code to determine the aging line includes: scanning the code at the loading position to determine whether aging is required. If aging is required, it is determined whether it should be aged in the current aging cabinet. If not, it is unloaded or transported forward. Before the product is loaded, scanning the code can obtain relevant information about the power amplifier, and judging whether normal aging or aging is required based on the power amplifier situation.

[0049] As an optional implementation, after determining the storage location information, the power amplifier is transported to the corresponding storage location, lifted, contacted, and powered on for testing, including:

[0050] The amplifier is transferred to the aging rack. If the bin information matches the ID of the aging rack, the amplifier is transported to the corresponding bin on the aging rack. If the bin information does not match the ID of the aging rack, the amplifier is transferred to other aging racks until it matches the ID of the aging rack and finds the corresponding bin, or if no match is found after transferring to all aging racks, the amplifier is removed from the aging rack and re-adjusted. For example, there are multiple aging racks, each with a unique ID. Because the amplifiers are selected according to type and have corresponding aging bins before being placed on the assembly line, which contain the aging rack ID, each amplifier to be tested and can be properly aged can be matched to the corresponding bin on the aging rack. In theory, the amplifier can be matched to the corresponding aging rack and find the corresponding bin on the aging rack by rotating in sequence. If it cannot be found, it may be that the match has been made, the amplifier has not been coded, or the generated QR code is incorrect. In any case, removing the amplifier from the aging rack and re-adjusting it can ensure that it can be handled even if an unexpected situation occurs.

[0051] As an optional implementation manner, transporting the power amplifier to a corresponding position on the aging rack includes:

[0052] carrying the power amplifier to a hoist;

[0053] The hoist allocates the amplifiers to the corresponding bins, where the bins are defined as follows: workshop, burn-in line corresponding to the burn-in rack, layer of the burn-in line, and bins corresponding to each layer. There are multiple burn-in lines, each with multiple layers, and each layer with multiple bins. For example, if there are eight burn-in lines, each with nine layers, and each layer with 20 bins, the workshop has 8*9*20=1440 bins, which means that theoretically, 1440 amplifiers can be burned in sequentially.

[0054] As an optional implementation, the lifting contact power-on test includes:

[0055] After the power amplifier is in place, the power amplifier is lifted up and powered on. The aging test after power-on includes but is not limited to heating test, voltage test, current test, distortion test, noise floor test, frequency response test, power test, playback test and other common test types involved in power amplifiers. During the aging test, the aging condition of the power amplifier is also recorded. For example, the aging time is selected according to the power amplifier condition or test requirements. After the aging time is over, the aging results are recorded, and the aging test type, aging time and aging results are uploaded to the server so that the aging results can be viewed after scanning the code. Moreover, the corresponding test process and aging results can also be viewed locally. The local monitoring equipment can be implemented through a customized industrial computer.

[0056] As an optional implementation, it includes: after the aging is completed and the aging result is displayed, Figure 2 As shown, it also includes the polyphonic steps:

[0057] S501: The hoist transports the power amplifier to the exit position;

[0058] S503, unloading the power amplifier from the unloading position to the transfer line and unloading to the retuning line;

[0059] S505: transport the power amplifier to a retuning station on the retuning line, and scan the code at the retuning station to obtain the aging result of the power amplifier;

[0060] S507: Determine whether to cut or re-adjust based on the aging result.

[0061] Among them, the discharge from the transfer line to the re-dispensing line can be realized automatically, the transfer from the re-dispensing line to the re-dispensing station can be realized manually, the code can also be scanned manually, the aging results can also be viewed manually, and subsequent judgment by visual means is also conceivable by those skilled in the art. The automatic control involved in the above steps can be realized by PLC control, for example, each aging rack is realized through IO network networking.

[0062] The present disclosure also provides a power amplifier automatic aging test system 100. Figure 3 Shown, including:

[0063] A code sticking station 1 is used to stick a QR code to the power amplifier, wherein the QR code is generated according to the product name, type, serial number, designated aging position and aging type;

[0064] Loading station 2 scans the power amplifiers transferred from the coding station and classifies them into different types of aging. If the aging is normal, the power amplifiers are manually wired and placed at the loading station. If the aging is not normal, the power amplifiers are released without wiring. If the aging is traditional, the products are unloaded for traditional aging testing.

[0065] The aging rack selects station 3. The amplifier after manual wiring is transferred to the aging line and matched with different aging rack IDs. If a match is found, the corresponding position is searched. If the IDs of all aging racks do not match after all aging racks have been transferred, the amplifier that has passed the station is transported out for retuning.

[0066] The power-on station 4 is lifted and powered on to test the power amplifier that has arrived at the corresponding position, and the aging data of the power amplifier under power-on test is monitored and timed until the aging is completed and the aging result is displayed.

[0067] As an optional embodiment, it also includes a retuning station 5, which is used to obtain product aging information of the power amplifier after aging is completed and the power amplifier that needs to be retuned in passing stations to determine whether to unload or return to the loading position for retuning.

[0068] The advantages or beneficial effects of the above technical solution include at least:

[0069] This disclosure classifies the amplifiers and then scans the code to determine the aging method. It can also automatically select the available slots for different aging methods based on the amplifier type, improving the degree of automation and allowing different types of amplifiers to be tested synchronously within the same aging system. This disclosure also provides a polyphonic line (polyphonic station) to enable polyphony for amplifiers that have passed through stations or have not been labeled. It can also determine whether to perform another aging test based on the aging test results.
