These screens primarily use thin films instead of glass covers to achieve bending and folding capabilities. With foldable and rollable characteristics, they can be applied to smartphones, wearable devices, automotive displays, and other fields. Flexible screens use flexible substrates, supporting free rolling with a bending radius of 1 mm. Some products are equipped with dynamic rolling and ultra-precision component control technologies.

[0003] With the widespread application of OLED flexible display technology in smartphones, wearable devices, and other fields, the requirements for its mechanical reliability are increasing. Impact resistance and micro-drop performance are key indicators for evaluating the quality of OLED flexible screens, directly affecting the product's lifespan and user experience in actual use.

Furthermore, traditional devices struggle to flexibly adjust drop angles and impact heights, failing to meet the standardized testing requirements of multiple angles and heights. Therefore, this OLED flexible screen impact and micro-drop testing device is proposed to address these issues. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 - Figure 3 An embodiment of this utility model provides an OLED flexible screen impact and micro-drop test device, including a base 1, a test mechanism 2 is provided on the top of the base 1, and a protective cover 4 is fixedly connected to the top of the base 1. The OLED flexible screen can be tested for impact and micro-drop resistance through the test mechanism 2.

[0030] The testing mechanism 2 includes a fixed frame 201. A motor 202 is fixedly connected to the top of the fixed frame 201. A lead screw 203 is fixedly connected to the output end of the motor 202. A lifting seat 204 is threadedly connected to the outer wall of the lead screw 203. By starting the motor 202 to drive the lead screw 203 to rotate, the position and height of the lifting seat 204 can be adjusted, thereby achieving the purpose of adjusting the drop height of the OLED flexible screen. A rotating shaft 205 is rotatably connected to the front of the lifting seat 204 via a bearing. A placement frame 206 is fixedly connected to the front end of the rotating shaft 205. A support plate 209 is fixedly connected to the front of the fixed frame 201. A cylinder 210 is fixedly connected to the upper surface of the support plate 209. A baffle 211 is fixedly connected to the telescopic end of the cylinder 210. An impact ball 213 is placed on the upper surface of the baffle 211. By activating the cylinder 210, the baffle 211 can be moved backward. When the baffle 211 moves out of the bottom of the impact ball 213, the impact ball 213 falls down to perform an impact resistance test on the OLED flexible screen. The position adjustment of the lifting seat 204 can adjust the distance between the OLED flexible screen and the impact ball 213.

[0031] Reference Figure 4 - Figure 5 The lower end of the fixing frame 201 is fixedly connected to the top of the base 1. The inner wall of the fixing frame 201 is fixedly connected to the guide rail 214. The side wall of the lifting seat 204 is slidably connected to the inner wall of the guide rail 214. The interior of the placement frame 206 is fixedly connected to the hydraulic cylinder 207. The telescopic end of the hydraulic cylinder 207 is fixedly connected to the clamping plate 208. By activating the hydraulic cylinder 207, the clamping plate 208 can be moved, thereby clamping and fixing the OLED flexible screen.

[0032] The side wall of the baffle 211 is slidably connected to the inside of the support plate 209. The upper surface of the support plate 209 is fixedly connected to the limit frame 212. The impact ball 213 is located inside the limit frame 212. The limit frame 212 can limit the position of the impact ball 213. There are two sets of hydraulic cylinders 207 and clamping plates 208. The two sets of hydraulic cylinders 207 and clamping plates 208 are respectively set on the left and right sides of the placement frame 206. The impact ball 213 is located directly above the placement frame 206. When a drop test is required, the hydraulic cylinder 207 can be activated to loosen the clamping plate 208 from the OLED flexible screen, causing the OLED flexible screen to fall and perform a drop test.

[0033] Reference Figure 3 , Figure 6 An adjustment mechanism 3 is provided on the outer wall of the lifting seat 204. The adjustment mechanism 3 includes a positioning plate 301. The inner wall of the positioning plate 301 is fixedly connected to the outer wall of the lifting seat 204. A positioning frame 302 is fixedly connected to the right wall of the placement frame 206. A positioning column 304 is slidably connected to the inner wall of the positioning frame 302. A spring 306 is sleeved on the outer wall of the positioning column 304. The horizontal angle of the placement frame 206 can be adjusted by the adjustment mechanism 3, so as to facilitate the OLED flexible screen to undergo drop tests at different angles.

[0034] A limiting block 305 is fixedly connected to the outer wall of the positioning post 304. One end of the spring 306 abuts against the front of the limiting block 305, and the other end of the spring 306 abuts against the inner wall of the positioning frame 302. A positioning hole 303 is provided on the front of the positioning plate 301. The rear end of the positioning post 304 is inserted into the inner wall of the positioning hole 303. A push plate 307 is fixedly connected to the right wall of the limiting block 305. When it is necessary to adjust the position and angle of the placement frame 206, the user can push the push plate 307 away from the positioning plate 301 to drive the limiting block 305, so that the limiting block 305 drives the positioning post 304 to disengage from the positioning hole 303 on the positioning plate 301. Then the placement frame 206 can be rotated to adjust the angle. After the adjustment is completed, the push plate 307 is released, so that the positioning post 304 is inserted into another positioning hole 303 under the action of the spring 306.

[0035] Working principle: During testing, the OLED flexible screen is fixed inside the placement frame 206. The hydraulic cylinder 207 is activated to push the clamping plate 208 to clamp the screen from both sides. The motor 202 drives the lead screw 203 to rotate, causing the lifting seat 204 to rise and fall vertically along the guide rail 214 on the inner wall of the fixed frame 201, thereby adjusting the vertical distance between the screen and the impact ball 213. During the impact test, the cylinder 210 retracts, causing the baffle 211 to be pulled away from the bottom of the impact ball 213, allowing the impact ball 213 to fall freely. When a micro-drop test is conducted by applying a fixed-point impact to the screen directly below, the hydraulic cylinder 207 retracts and releases the clamping plate 208, allowing the screen to fall freely from the placement frame 206 onto the surface of the base 1. If the drop angle needs to be adjusted, the push plate 307 is manually pulled, and the positioning pin 304 compresses the spring 306 and disengages from the positioning hole 303 of the positioning plate 301. After rotating the placement frame 206 to the target angle, the push plate 307 is released, and the spring 306 pushes the positioning pin 304 to insert into the corresponding positioning hole 303 to complete the locking.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
