Description

Technical Field

[0001] The present invention relates to the technical field of automated testing, and in particular to a Dock connector automatic testing device. Background Art

[0002] The dock connector is a data connector for smartphones. Installed inside a smartphone, it's a connection module comprised of a circuit board, connecting cables, and various electronic components. After production, it undergoes a series of performance tests (including B2B connectivity, microphone, charging connections, and more) to ensure product yield. Therefore, multiple connection points must be tested during testing. Currently, manufacturers generally use automated testing equipment to inspect dock connectors. Because dock connectors require numerous test items, multiple testing organizations or equipment are typically required to perform these tests in rotation.

[0003] Currently, the typical testing method used by companies involves securing the product under test (i.e., the dock connector) to a fixture, which is then transported by a conveyor line. Testing equipment is then installed along the conveyor line to test different performance characteristics of the product under test. However, this testing method requires a large area to accommodate the various devices, which takes up a lot of space. Furthermore, when problems arise, operators are unable to troubleshoot or resolve them promptly, hindering production management and reducing testing efficiency. Summary of the Invention

[0048] In this embodiment, the limit positioning assembly 62 includes a front positioning block 621 arranged on the jig plate 61, and the first limit blocks 622 are provided at both ends of the upper end face of the front positioning block 621, and a plurality of positioning blocks 623 are provided between the two first limit blocks 622. The rear side of the front positioning block 621 is provided with a middle limit block 624, and the left and right ends of the upper end face of the middle limit block 624 are provided with second limit blocks 625. The left and right ends of the rear side of the middle limit block 624 are respectively provided with a left rear limit block 626 and a right rear limit block 627. The left rear limit block 626 is provided with an interlocking groove 628, and the front, rear and right sides of the right rear limit block 627 are provided with limit columns 629. The limiting and positioning assembly 62 includes a front positioning block 621, a middle limiting block 624, a left rear limiting block 626 and a right rear limiting block 627. The front positioning block 621, the middle limiting block 624, the left rear limiting block 626 and the right rear limiting block 627 are sequentially arranged on the jig plate 61 from front to back. The two first limiting blocks 622 on the front positioning block 621 can limit the front part of the Dock joint, and the two second limiting blocks on the middle limiting block 624 can limit the front part of the Dock joint. Block 625 can limit the middle part of the Dock connector, the engaging groove 628 on the left rear limiting block 626 can limit the left part of the rear fork of the cable of the Dock connector, and the three limiting columns 629 on the right rear limiting block 627 can limit the right part of the rear fork of the cable of the Dock connector. As can be seen from the above, the limiting and positioning assembly 62 can well limit and position the Dock connector with high positioning accuracy, thereby facilitating the testing work.
