Description

Technical Field

[0001] The utility model belongs to the technical field of power-on detection and relates to a power-on test mechanism for automatically detecting a wireless charging module. Background Art

[0002] The existing wireless charging module power-on test is performed by contact testing with a concave needle. During the test, the concave needle has a fixed contact method, lacks flexibility, and has low positioning accuracy. If the concave needle is slightly off, it will easily break.

[0003] The plug-in detection method in the prior art is to perform alignment plug-in by moving the concave pin forward, backward, left and right. The disadvantages of this plug-in method are: the fixing method is not flexible, which can easily damage the concave pin and the pin part of the wireless charging module. It has a short service life and a small contact area, which requires high positioning accuracy, resulting in high manufacturing costs, high maintenance and replacement costs, and a long processing time for supporting parts, which increases manufacturing costs.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A power-on test mechanism for automatically detecting a wireless charging module comprises: a distribution box, a discharge unit disposed in the distribution box, and an assembly unit disposed at the upper end of the distribution box;

[0006] The assembly unit includes: a detection fixture for placing the wireless charging module, with a rotating pressing mechanism provided on both sides of the detection fixture;

[0007] The discharge unit includes: a detection group for performing discharge detection on the wireless charging module and a detection cylinder for driving the detection group to push up;

[0008] The detection group includes: a needle block, a test needle, a needle block and a needle block mounting base; the needle block mounting base is installed on the piston rod of the detection cylinder;

[0009] The needle block is mounted on the needle block mounting seat, and the needle block and the test needle are both mounted on the needle block, with the upper end of the test needle penetrating into the needle block;

[0010] The inspection group also includes: a punch screw and a spring. The needle block is formed with a through-counter-bored hole, and the needle block mounting base is formed with a threaded hole for the punch screw. The threaded section of the punch screw passes through the counter-counter-bored hole and cooperates with the threaded hole to achieve the connection between the needle block and the needle block mounting base. The diameter of the counter-counter-bored hole is larger than the diameter of the punch screw.

[0011] The needle block mounting seat is formed with a spring hole for spring installation. The spring is set in the spring hole, and the upper end is against the needle block, so that the needle block can achieve a floating effect front, back, left and right.

[0012] As a further solution of the present invention: the test needle in the detection group adopts a plum blossom needle structure.

[0013] As a further solution of the present invention: the rotary pressing mechanism includes: at least four groups of rotary pressing cylinders, evenly distributed on both sides of the detection fixture, and mounting blocks are installed on the piston rods of the rotary pressing cylinders.

[0014] As a further solution of the present invention: an acrylic protective cover is provided on the distribution box to semi-enclose and cover the rotating and pressing mechanism.

[0015] As a further solution of the present invention: the discharge unit also includes: a set of cylinder seat plates for achieving stable installation of the detection cylinder, and the detection cylinder is fixed in the distribution box through the cylinder seat plates.

[0016] The beneficial effects of the present invention are as follows: by replacing the traditional concave needle with a plum blossom head test needle structure, the contact area between the needle and the wireless charging module product is increased; by adopting a flexible plug-in structure, the needle block and the test needle can float back and forth and left and right, ensuring stable contact with the probe part of the wireless charging module. Through this mechanism, the probe of the wireless charging module can be contacted, preventing the failure of power supply due to the tolerance of the probe of the wireless charging module, and also ensuring the service life of the pin.
