Description

Technical Field

[0001] This utility model relates to the field of electronic equipment production and testing technology, and in particular to an automatic aging line for power amplifiers. Background Technology

[0002] Power amplifiers play a crucial role in electronic products, and their performance stability and reliability directly impact the quality of the entire electronic system. To ensure stable and reliable operation of power amplifiers after leaving the factory, aging tests are required during production to screen for potential early failures and to stabilize the amplifier's performance. Traditional aging tests typically involve manually connecting each amplifier to an aging test device, powering it on for a certain period, and then manually removing it for performance testing. This manual approach has many drawbacks, such as low efficiency, high labor costs, susceptibility to human error leading to testing errors and product damage, and difficulty in achieving large-scale, standardized aging test procedures, failing to meet the demands of efficient and high-quality production in modern electronic products. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide an automatic aging line for power amplifiers.

[0004] To achieve the above objectives, this utility model provides an automatic power amplifier aging line, characterized in that it includes a frame, a conveying mechanism, a feeding device, a testing device, a parameter adjustment device, a storage device, and a recirculation processing device disposed within the frame. The conveying mechanism is used to transport the power amplifier products to be tested between the various devices. The parameter adjustment device is used to set the working parameters for the aging test. The conveying mechanism is used to transport the power amplifier products to be tested supplied by the feeding device to the testing device for aging testing. The conveying mechanism transports the power amplifier products that pass the test to the storage device and the power amplifier products that fail the test to the recirculation processing device.

[0005] Furthermore, the testing device includes a first conveyor line mounted on a rack, a first test component mounted on the first conveyor line for testing power amplifier products, and a drive component, wherein the drive component drives the first conveyor line to transport the power amplifier products to the first test component.

[0006] Furthermore, the first test component includes a base set on the first conveyor line for placing the power amplifier product, and a test element set on the base for aging test of the power amplifier product. The first conveyor line transports the power amplifier product to the base for aging test by the test element.

[0007] Furthermore, the test component includes a power connection port, a signal input port, and a signal output port. The power amplifier product is placed on the base and connected to the power connection port to be powered on. An external signal source inputs a test signal to the power amplifier product through the signal input port. The power amplifier product amplifies the input signal, and the amplified signal is output to an external aging test device through the signal output port for aging test.

[0008] Furthermore, the parameter adjustment device has a resistor system, which includes resistors mounted on the rack and resistor brackets for fixing the resistors. The resistors simulate actual loads, putting the power amplifier product under near-realistic operating conditions, thereby more accurately testing its performance stability and aging under load.

[0009] Furthermore, the parameter adjustment device has a lifting system, which includes a cylinder installed on the first conveyor line and a limiting plate installed at the output end of the cylinder. The limiting plate is used to limit the power amplifier product, and the cylinder is used to lift or lower the power amplifier product limited by the limiting plate. The cylinder drives the limiting plate to push the power amplifier product to connect with the testing device.

[0010] Furthermore, the reflow processing device includes a storage cabinet mounted on a rack for storing power amplifier products, a fourth conveyor line for transporting defective power amplifier products, a second testing component mounted on the storage cabinet, and a power source. The power source transports the power amplifier products that fail the test by the testing device to the storage cabinet via the fourth conveyor line. The defective power amplifier products are stacked in an orderly manner on the layered shelves of the storage cabinet. The second testing component performs a second aging test on the defective power amplifier products on the storage cabinet. The power amplifier products that have passed the second aging test enter the subsequent processing steps. The storage cabinet is located at the end of the second conveyor line.

[0011] Furthermore, the conveying mechanism includes a column rotatably mounted on the second conveying line, a telescopic first arm mounted on the column, a second arm rotatably mounted at the end of the first arm, an end effector for clamping the power amplifier product at the end of the second arm, and a power component. The power component drives the column to rotate, the column drives the first arm, and the first arm drives the end effector to clamp the power amplifier product and convey it to the testing device.

[0012] Furthermore, the rack is equipped with ventilation and heat dissipation windows.

[0013] Furthermore, the rack is equipped with inserts to facilitate the installation and removal of external equipment.

[0014] The beneficial effects of this utility model are:

[0015] (1) Automated process ensures efficient operation: The entire aging line integrates feeding, testing, discharging, and handling of defective products. All parts work together to achieve automated assembly line operation. The feeding device can continuously transport the power amplifier products to be tested to the testing device, avoiding the tedious operation of manually handling and placing them one by one. This greatly improves the speed at which products enter the aging test stage, significantly improving the overall testing efficiency and enabling more power amplifier products to be processed per unit time.

[0016] (2) Comprehensive testing and screening: Through a complete aging test process, the power amplifier products are subjected to comprehensive performance testing, which can effectively discover potential quality problems. Products that pass the aging test are output through the discharge device, while unqualified products are sent to the recirculation processing device for subsequent analysis and processing. This achieves strict control over product quality, ensuring that the power amplifier products flowing to the market have undergone strict quality inspection, have higher reliability, and reduce after-sales problems caused by product quality issues.
