Description

Technical Field

[0001] The utility model relates to the field of circuit board detection, in particular to a module testing fixture. Background Art

[0002] There are multiple processes for production inspection during the production of circuit boards, but traditional inspection tools, such as FPC board testing, can easily damage the connector, causing test failure or even burning the product. Some are not properly aligned, resulting in various product defects. In addition to the above problems, simple POGOPIN fixtures are also easy to damage the test probes, affecting costs. At the same time, some fixtures will freeze in rotation and become weak in pressing due to long-term rotation and pressing during testing, which will eventually affect the test structure.

[0003] In order to solve the problems of weak fixed pressing and easy damage to products that may occur during mold testing, a simple optimization solution is now provided. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A module testing fixture comprises: a bottom frame, a detection plate, and a placement frame, wherein the placement frame is fixed at the center position of the bottom frame, and the detection plate is fixed at the lower part of the bottom frame, wherein the detection plate is composed of a flip cover and a base, the flip cover is provided with a limiting hole, the upper part of the base is fixed with a fixing platform, the lower part of the base is fixed with a tablet pressing device, and the limiting hole cooperates with the tablet pressing device.

[0006] Preferably, the fixed platform structure is a rectangular structure, the fixed platform structure is higher on the left and right sides and lower in the middle, the fixed platform is convex on the left and right sides, a first groove and a second groove are arranged in the middle of the fixed platform, and a magnet is arranged on the second groove.

[0007] Preferably, the tablet pressing device comprises: a tablet pressing seat, a tablet pressing and a rotating shaft, the tablet pressing seat is fixed on the base, the tablet pressing seat structure is a "concave" shaped structure, a rotating shaft is installed in the middle part of the tablet pressing seat, and the tablet pressing is fixed on the rotating shaft.

[0008] Preferably, the sheet pressing seat includes: a pressure plate, a spring and a rotating hole. The rotating holes are opened inside the left and right protrusions of the sheet pressing seat. The rotating shaft is installed in the rotating hole. The pressure plate is attached to the upper surface of the rotating shaft. One end of the spring is fixed on the pressure plate, and the other end of the spring is fixed on the inner wall of the rotating hole.

[0009] Preferably, the pressing sheet structure is a "7"-shaped structure, and the pressing sheet includes: a pressing part, a positioning part and a through hole, the through hole is connected to the rotating axis, the pressing part and the positioning part are perpendicular, the pressing part structure is stepped and gradually narrows from bottom to top, and the positioning part structure is "T"-shaped. Beneficial Effects

[0010] The utility model provides a fixed platform and a tablet pressing seat. When testing, the magnet on the fixed platform can attract the product to be tested, so that the product is firmly attached to the fixed platform. At the same time, the tablet on the tablet pressing seat cooperates with the tablet to further fit the product to be tested through a rotating pressing part, so that the product testing data is stable. At the same time, when testing, the positioning part on the tablet cooperates through the limiting hole of the flip cover, which can ensure that the product is installed in place, ensure the reliability of product testing, and prevent damage to the product when the flip cover is closed, thereby affecting product testing.

[0011] The utility model provides a tablet pressing seat, and the downward pressure of the spring in the rotating hole of the tablet pressing seat tightly presses the rotating shaft. While pressing the rotating shaft, the entire tablet pressing will also have a downward pressure, thereby increasing the downward pressure of the tablet pressing, so that the product can fit the detection tool tightly and the product will not be offset. Since the rotating shaft is installed by the pressure plate and the spring, it has the ability to move up and down when rotating, which can ensure the smoothness of the tablet pressing when rotating, thereby increasing the service life of the device and saving tool costs.

[0031] Working principle:

[0032] A module test fixture comprises: a bottom frame 1, a test board 2 and a placement frame 3. When testing, a mobile phone screen and an FPC are fixed, and the front of the mobile phone screen is placed in the placement frame with the front side facing upward. The ends of the FPC to be tested are respectively placed in the first groove 232 and the second groove 233 of the test table 2. At this time, a magnet 24 will attract the ends of the FPC. After stabilization, a pressing sheet 26 is rotated. After rotation, a pressing portion 261 will tightly press the ends of the FPC. At this time, a positioning portion is erected. After the positioning portion 262 is erected, a flip cover 21 is covered. At this time, a limit hole 211 will be aligned with the positioning portion and covered normally. If it is not aligned, the flip cover will not cover it. At this time, the pressing sheet needs to be adjusted to see if the ends of the FPC have been compacted. If not, the test cannot be carried out normally. After everything is normal, the test can be carried out. The test process ensures the stable fitting of the product and ensures that the product test is not damaged, which greatly improves the test efficiency and saves the test cost.
