Description

Technical Field

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

[0002] Mobile phone screens are used to display images and colors, hence they are also called displays. The screen material, screen color, brightness, contrast and other factors determine the screen quality. Mobile phone screens also need to undergo defect testing to check whether the quality of the mobile phone screen meets the qualified standards. Only after passing the test can it enter the next process. Mobile phone screens with quality defects must be marked and returned for repair to prevent the circulation of defective products.

[0003] Reference Publication No.: CN215640690U, specifically "A Mobile Phone Display Screen Scratch-Resistant Detection Device". This utility model discloses a mobile phone display screen scratch-resistant detection device, relating to the field of display screen scratch-resistant detection technology. It includes a base plate with a first groove inside, a first slider slidably connected inside the first groove, and clamping plates fixedly connected to the top of the first slider and one side of the top of the base plate. A display screen body is placed between the two clamping plates, and a first electric telescopic rod is provided on one side of the top of the base plate. A support frame is fixedly connected to the output end of the first electric telescopic rod. This design places the first groove, first lead screw, and first slider on the upper surface of the base plate. During the scratch-resistant detection of the display screen body, debris is easily generated. This debris easily enters the first groove and adheres to the first lead screw. Dust may increase the friction between the first lead screw and the first slider, making the movement of the first slider less smooth or difficult. Furthermore, excessive dust accumulation may also lead to accelerated wear of the first lead screw and the first slider, affecting their service life. To change this situation, a mobile phone display screen detection device is proposed here. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mobile phone display screen detection device.

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

[0006] A mobile phone display screen testing device includes a base plate, two clamping plates, and a display screen body. Multiple support legs are installed on the bottom of the base plate. Two rotating grooves are provided on the bottom wall of the base plate, and a double-ended screw rotates within both grooves. A drive motor connected to the double-ended screw is provided on one outer wall of the base plate. A nut is threaded onto the double-ended screw, and a connecting frame is provided on the nut via a synchronization mechanism. The connecting frame is connected to the base plate via a limiting mechanism and to the clamping plates via an insertion mechanism.

[0007] Preferably, the synchronization mechanism includes a synchronization block disposed on the outer wall of the nut, and the surface of the connecting frame that contacts the nut is provided with a synchronization groove corresponding to the synchronization block.

[0008] Preferably, the limiting mechanism includes two inserts mounted on the connecting frame, and the outer walls on both sides of the base plate are provided with limiting grooves corresponding to the inserts located below.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A mobile phone display screen testing device includes a base plate 1, two clamping plates 4 and a display screen body 5. The base plate 1 is not completely shown in this solution. The part not shown is also equipped with components such as a first electric telescopic rod through a second slider. For details, please refer to the disclosure (announcement) number: CN215640690U. This solution does not improve on it. Therefore, the other equipment components are not disclosed in this solution.

[0023] The bottom of the base plate 1 is equipped with multiple support legs 2, which are conventional support components that provide normal support for the base plate 1 and other components. The bottom wall of the base plate 1 has two rotating grooves 11, and a double-headed screw 12 is rotatably mounted in both rotating grooves 11. A drive motor 3 connected to the double-headed screw 12 is mounted on one outer wall of the base plate 1. A nut 13 is threaded onto the double-headed screw 12. A connecting frame 7 is mounted on the nut 13 through a synchronization mechanism. The connecting frame 7 is connected to the base plate 1 through a limiting mechanism and is connected to the clamping plate 4 through an insertion mechanism.

[0024] The synchronization mechanism includes a synchronization block 14 disposed on the outer wall of the nut 13. The surface of the connecting frame 7 that contacts the nut 13 is provided with a synchronization groove 15 corresponding to the synchronization block 14. The part of the connecting frame 7 that connects to the nut 13 is arranged in a U-shape. After the synchronization block 14 is inserted into the synchronization groove 15, when the nut 13 moves on the double-ended screw 12, the connecting frame 7 can move synchronously.

[0025] The limiting mechanism includes two insert blocks 10 mounted on the connecting frame 7. The outer walls on both sides of the base plate 1 are provided with limiting grooves 8 corresponding to the lower insert blocks 10. The limiting grooves 8 are horizontally T-shaped. When the insert blocks 10 move to the vertical part of the limiting grooves 8, the connecting frame 7 can descend directly along with the insert blocks 10. The connecting frame 7 disengages from the nut 13, and the insert blocks 10 disengage from the limiting grooves 8 and the snap-fit ​​grooves 9.

[0026] The insertion mechanism includes a snap-fit ​​groove 9 on the clamping plate 4, which corresponds to the upper insertion block 10. When one of the insertion blocks 10 is in the snap-fit ​​groove 9, the connecting frame 7 moves with the nut 13, thereby realizing the synchronous movement of the clamping plate 4.

[0027] Protective pads 6 are provided on the surfaces of the two clamping plates 4 that contact the display body 5. The protective pads 6 are made of rubber and have anti-slip textures on the surfaces that contact the display body 5. The rubber protective pads 6 with anti-slip textures protect the clamping part of the display body 5 and ensure anti-slip properties during clamping.

[0028] A limiting rod 16 is provided in both rotating slots 11. The limiting rod 16 is parallel to the double-ended screw 12. The limiting rod 16 slides through the nut 13. The limiting rod 16 realizes the limiting of the nut 13, thereby effectively preventing it from rotating with the double-ended screw 12.

[0029] When this utility model is in use, the double-ended screw 12 is driven to rotate by the drive motor 3. When the double-ended screw 12 rotates, the nut 13 installed on its thread will drive the connecting frame 7 to move synchronously with the synchronous block 14. The two connecting frames 7 move closer and drive the clamping plate 4 to move closer, finally realizing the clamping and fixing of the display screen body 5. Then, its scratch resistance performance can be tested with the help of the detection component. The debris generated during the test will not enter the rotating groove 11, so it will not affect the movement of the nut 13 on the double-ended screw 12.

[0030] In this solution, the clamping plate 4 can be directly lifted to complete the disassembly from the connecting frame 7, thereby facilitating the replacement of the clamping plate 4. The clamping plate 4 of different heights can be replaced for display screen bodies 5 of different thicknesses.

[0031] In this design, the connecting frame 7 and other components can be easily disassembled from the double-ended screw 12, nut 13, and base plate 1. After disassembly, it is convenient to lubricate the double-ended screw 12. Specifically, the double-ended screw 12 is kept rotating so that it drives the nut 13 to move to a position close to the end of the rotating groove 11. The connecting frame 7 will move synchronously with the nut 13, and the insert 10 on the connecting frame 7 will move synchronously on the limiting groove 8. When the insert 10 moves to the vertical part of the limiting groove 8, the connecting frame 7 loses its vertical limit and falls directly to disengage from the nut 13. In the disengaged state, it can be removed, and then the above-mentioned lubrication operation can be performed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
