Description

Technical Field

[0001] This utility model relates to the field of mobile phone screen testing technology, and in particular to a testing fixture for mobile phone screens. Background Technology

[0002] With the rapid development of electronic technology, mobile phones are being updated and replaced at an even faster pace. As mobile phones become more and more popular, a lot of second-hand mobile phones are left behind. After recycling second-hand mobile phones, it is necessary to inspect the screens. This mainly involves inspecting the screen's connectivity and damage. It is also necessary to display a full-color photo of the screen to conduct a detailed inspection of the screen's display function. The main inspection method is still manual observation.

[0003] Current mobile phone screen inspection fixtures use multiple clamping blocks to fix the mobile phone before inspection. However, when inspecting curved mobile phones, the phone needs to display a full-color photo for manual observation. In this case, the clamping blocks may block the sides of the curved screen, affecting the inspection of the curved mobile phone. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a testing fixture for mobile phone screens that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A testing fixture for mobile phone screens includes: a fixed platform; a controller fixedly disposed on one side of the fixed platform; a control screen disposed on the side of the fixed platform near the controller; a clamping assembly for clamping and positioning the mobile phone screen disposed on the fixed platform; a through groove disposed on the fixed platform; a first electric telescopic rod fixedly disposed in the through groove; and a suction cup fixedly disposed at the output end of the first electric telescopic rod, wherein the suction cup is matched with the through groove.

[0007] To facilitate the clamping of the mobile phone, the clamping assembly further includes multiple second electric telescopic rods fixed on the fixed platform, and the output end of the second electric telescopic rod is fixedly connected to a pressing rod.

[0008] Preferably, a rubber pad is fixedly connected to the end of the extrusion rod.

[0009] To further facilitate the protection of the mobile phone camera, a sponge layer is fixedly connected to the mounting platform, and the sponge layer matches the through groove.

[0010] To ensure the phone screen remains horizontal, a third electric telescopic rod is symmetrically fixedly connected to the fixed platform. A connecting plate is rotatably mounted on the telescopic end of the third electric telescopic rod, and a fixed rod is fixedly connected to the end of the connecting plate. A smooth block is provided at the lower end of the fixed rod, and a buffer block is fixedly connected between the smooth block and the fixed rod.

[0011] To facilitate support of the lower part of the mobile phone, multiple support blocks are further fixedly connected to the fixing platform.

[0012] Compared with the prior art, this utility model provides a testing fixture for mobile phone screens, which has the following beneficial effects:

[0013] 1. This testing fixture for mobile phone screens uses a controller to extend corresponding second electric telescopic rods to clamp and position the mobile phone, effectively fixing it for easy inspection. When full-color display testing of the mobile phone screen is required, the controller extends corresponding first electric telescopic rods to a specified height, where multiple suction cups adhere to the bottom of the phone for fixation. Then, the controller retracts multiple second electric telescopic rods, releasing the clamping rods from their limiting position on the phone, effectively preventing the clamping rods from obstructing the curved edges of the mobile phone screen and affecting the inspection process.

[0014] 2. This testing fixture for mobile phone screens uses multiple second electric telescopic rods that extend a certain distance, with the actual extension distance of the second electric telescopic rods being 5 millimeters less than the expected extension distance. Then, the operator rotates the connecting plate, placing two smooth blocks on the upper side of the mobile phone screen. The controller then controls the third electric telescopic rod to retract, and the smooth blocks apply a downward pressing force to the mobile phone screen, causing the lower end of the phone to contact the support block. The camera part of the phone is then squeezed into the sponge layer. Finally, the controller controls the multiple second electric telescopic rods to extend to the designated position to fix the phone, thereby effectively preventing the phone camera from causing the phone to tilt and affecting its positioning effect.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model effectively prevents the squeezing rod from obscuring the edge of the curved mobile phone screen and affecting the operator's inspection, while also effectively preventing the mobile phone camera from causing the phone to tilt and affecting its positioning effect.
