Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, specifically an EOL testing fixture. Background Technology
[0002] Test fixtures are specialized tools used on electronic product production lines to perform final functional tests on products that are about to come off the line. They are mainly used to comprehensively test the various functions of the product, promptly identify problems and defects in the product, and ensure that only qualified products can enter the market, thereby improving the overall quality and reliability of the product and reducing the risks of after-sales maintenance and customer complaints.
[0003] Currently, most testing fixtures on the market require manual loading, followed by manual scanning of the QR code on the label using a barcode scanner. The label color is also manually judged to ensure it is correct. Then, the clamp probe is manually pulled down to press the product from top to bottom for testing. Furthermore, the testing functions are limited and cannot be compatible with Faker connector and USB connector testing functions. Currently, manual labor is intensive, involves too much intervention, and has a high error rate. The label information data cannot be uploaded to the MES system. Utility Model Content

[0027] Working principle: In this EOL testing fixture;
[0028] When using the EOL test fixture, the product is first placed manually into the carrier on the cavity assembly 4 and the carrier is pushed to the designated position. Then, the automatic lifting is started by the cylinder 47 below, so as to lock the fixture in conjunction with the push rod 42. Next, the USB test module in the test assembly 5 is pushed forward by the operator, causing the test module to simultaneously squeeze the micro switch 43 and the operator leaves.
[0029] Automatic testing begins with the structure of the barcode scanning component 6. The color sensor 65 detects the color of the label, and the barcode scanner 63 scans the QR code on the label. Once the test is complete, the process moves to the next step. Automatic testing begins simultaneously with the 12-pin probe 57, the first test head 55, the second test head 56, and the USB test head 46 in the testing component 5. The test results are automatically displayed on the monitor. After the test is successful, the cylinder 47 automatically retracts, and the USB test head 46 is manually pulled out to remove the tested product. If the test fails, the pull-out box 2 is manually pulled out, the cylinder 47 automatically retracts, and the USB test head 46 is manually pulled out to remove the failed product. This allows personnel to individually control the action and parameter settings of each cylinder through the monitor, facilitating equipment debugging. During operation, the three-color alarm light illuminates different colors and a buzzer sounds according to the operating status. All actions are determined by sensors.
