The following embodiments are used to illustrate the present utility model, but do not limit the scope of the present utility model.

[0036] As Figure 1-8 shown, the present utility model specifically relates to a test device for curved screen testing.

The rotating shaft 211 is rotatably connected to the two support columns 210 through bearings. Both ends of the rotating shaft 211 are connected to the clamping assembly 203 through connection blocks 212.

[0041] In the utility model, the first driving member 202 drives the slide seat 206 to reciprocate. The slide seat 206 drives the vertical plates 207 to move. The two rollers 209 of the clamping assembly 203 roll in the inclined grooves of the vertical plates 207 at the same time, so as to realize that the clamping assembly 203 driven by the first driving member 202 rotates around the rotating shaft 211, and further realize that the curved screen arranged on the upper part of the clamping assembly 203 always remains perpendicular to the detection mechanism 300, ensuring the accurate detection of the curved screen.

[0042] At the same time, the second module 302 drives the second mounting bracket 304 to move along the length direction of the curved screen. The function camera 305 and the brightness sensor 308 on the second mounting bracket 304 detect the curved screen. At the same time, the controller controls the moving distance of the first driving member 202 to drive the slide seat 206, so that the function camera 305 and the brightness sensor 308 always remain perpendicular to the curved screen. The automation degree of this device is high.

The moving end of the second driving member 2033 is connected to the limiting member 2034. The second driving member 2033 drives the limiting member 2034 to move. The first insertion strip 20343 and the second insertion strip 20344 on the limiting member 2034 can be inserted into the interior of the curved screen to realize the fixation of the curved screen.

A number of limit sensors 20363 included in the detecting member 2036 can detect whether the curved screen is installed in place in the vertical direction. If the curved screen is not installed in place, the limit sensors 20363 will transmit signals to the controller, and the controller will control the alarm to give an alarm.

[0048] Through the setting of the "Z"-shaped limiting plate, the first limiting plate 20341 and the second limiting plate 20342 are not at the same height, which is convenient for fixing the curved screen.

[0049] The detecting member 2036 includes a first mounting frame 20361, a number of mounting blocks 20362 and a number of limit sensors 20363. The number of mounting blocks 20362 are arranged on one side of the first mounting frame 20361. The number of limit sensors 20363 are arranged in sequence on one side of the number of mounting blocks 20362.

[0050] It should be further noted that a first module 101 and two third slide rails 102 are provided on the upper part of the base 100. The two third slide rails 102 are connected to the bottom plate 201 through third sliders 103.

[0051] It should be particularly noted that, as shown in Figure 6 the detection mechanism 300 includes a bracket 301, a second module 302, a third module 303, and a second mounting bracket 304. The second module 302 is provided on the upper part of the bracket 301. The third module 303 is connected to the mobile end of the second module 302. The second mounting bracket 304 is connected to the mobile end of the third module 303. A function camera 305 is provided on the upper part of the second mounting bracket 304, and an industrial camera 306, a distance sensor 307, and a brightness sensor 308 are provided on the lower part of the second mounting bracket 304.

[0052] The function camera 305 is used to detect the function image of the curved screen. The brightness sensor 308 can measure the brightness of the function image of the curved screen. The industrial camera 306 is used for visual positioning of the curved screen and transmits signals to the controller. The controller controls the second module 302 to drive the second mounting bracket 304 to move along the length direction of the curved screen.

[0053] Finally, as shown in Figure 8 a fourth driving member 309 is further provided on one side of the second mounting bracket 304. A pressing finger assembly 310 is provided on the lower part of the fourth driving member 309. The fourth driving member 309 can drive the pressing finger assembly 310 to reciprocate vertically.

[0054] The pressing finger assembly 310 includes a connecting plate 3091, a bearing seat 3092, a guiding shaft 3093, a fixing nut 3094, an elastic member 9095, and a contact head 3096.

A limiting disc 3097 is provided on the upper part of the guiding shaft 3093.

[0055] The fourth driving member 309 drives the contact head 3096 to reciprocally touch the curved screen to simulate the state of the curved screen in the actual operation environment. When the contact head 3096 touches the curved screen, the contact head 3096 will move upward to compress the elastic member 9095, preventing the contact head 3096 from rigidly contacting the curved screen and damaging the curved screen.

[0056] Working principle:

[0057] The first module 101 drives the clamping mechanism 200 to move to one end of the base 100. The curved screen is transported to the upper part of the clamping mechanism 200 by a manipulator. The second driving member 2033 drives the limiting member 2034 to move. The first insert bar 20343 and the second insert bar 20344 on the limiting member 2034 can be inserted into the interior of the curved screen to fix the curved screen. At the same time, the third driving member 2035 drives the detecting member 2036 to move upward. After moving to a preset position, several limit sensors 20363 included in the detecting member 2036 can sense the curved screen, indicating that the curved screen is installed in place. If not sensed, it means the installation is not in place. After the installation is in place, the first module 101 drives the clamping mechanism 200 to move to the detection station at the other end of the base 100;

[0058] The second module 302 drives the second mounting bracket 304 to move along the length direction of the curved screen. The function camera 305 and the brightness sensor 308 on the second mounting bracket 304 detect the curved screen. At the same time, the controller controls the distance that the first driving member 202 drives the slide 206 to move, always keeping the function camera 305 and the brightness sensor 308 perpendicular to the curved screen. Synchronous control belongs to the technology of software programming and will not be elaborated too much in this utility model. At the same time, the third module 303 drives the second mounting bracket 304 to move up and down reciprocally, and measures the distance from the curved screen through the distance sensor 307, so that a certain distance is maintained between the second mounting bracket 304 and the curved screen to ensure the normal detection of the curved screen by the brightness sensor 308 and the function camera 305.

[0059] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
