The clamping module 20, the display detection module 30 and the touch detection module 40 are connected to the base plate 10 respectively.

[0062] The base plate 10 is used to carry the clamping module 20, the display detection module 30 and the touch detection module 40, and to maintain the relative position relationship between the clamping module 20, the display detection module 30 and the touch detection module 40. The clamping module 20 is used to clamp and fix the screen to be tested ( Figure 1 The display detection module 30 is used to detect the display performance of the screen under test (not shown), and can adjust the angle at which the screen under test is clamped. In this embodiment, display performance includes one or any combination of color reproduction, brightness uniformity, color uniformity, white balance, signal-to-noise ratio, and viewing angle. The touch detection module 40 is used to detect the touch performance of the screen under test. In this embodiment, the touch detection module 40 is used to perform a click burn-in test on the screen under test.

[0063] The bottom plate 10 is a generally rectangular plate structure having a first surface 11 and a second surface 12 that are opposite and parallel to each other. Figure 1 and Figure 2 The clamping module 20 is connected to the first surface 11 and the second surface 12. The display detection module 30 is fixedly connected to the first surface 11. The touch detection module 40 is connected to the first surface 11. The clamping module 20, the display detection module 30, and the touch detection module 40 are spaced apart from each other and are located on different sides of the first surface 11.

[0064] See also Figure 3 The clamping module 20 includes a mounting assembly 21, a clamping assembly 22, and a lifting assembly 23. The clamping assembly 22 is connected to the mounting assembly 21. The lifting assembly 23 is connected to the mounting assembly 21 and the clamping assembly 22, respectively, and is used to drive the clamping assembly 22 to translate (or lift) relative to the mounting assembly 21 along the first direction L1. In this embodiment, the first direction L1 is perpendicular to the first surface 11 (see FIG. Figure 1 ).

[0065] The screen detection device 1 of the present application further includes a rotating module 60 connected to the mounting assembly 21 for driving the clamping module 20 to rotate around the axis L0. Figure 2 and Figure 3 In this embodiment, the axis L0 is perpendicular to the first surface 11 of the base plate 10 .

[0066] The mounting assembly 21 includes a turntable 211 and a vertical plate 212 fixedly connected to the turntable 211. The turntable 211 is movably connected to the first surface 11. The vertical plate 212 is fixedly connected to the surface of the turntable 211 away from the bottom plate 10 and is located at the edge of the surface. In this embodiment, the turntable 211 is a circular thin plate structure; the vertical plate 212 is a rectangular thin plate structure, having a rectangular mounting surface 2121 perpendicular to the first surface 11. The clamping assembly 22 is movably connected to the mounting surface 2121, the lifting assembly 23 is respectively connected to the clamping assembly 22, the turntable 211 and the vertical plate 212, and the rotating module 60 is connected to the turntable 211.

[0067] The clamping assembly 22 includes a clamping platform 221, a first clamping structure 222, a second clamping structure 223, a first stress strain gauge 224, and a second stress strain gauge 225. A recess 2211 is defined on the surface of the clamping platform 221, away from the vertical plate 212. The first clamping structure 222 and the second clamping structure 223 are partially located within the recess 2211. The first stress strain gauge 224 is connected to the first clamping structure 222, and the second stress strain gauge 225 is connected to the second clamping structure 223.

[0068] In this embodiment, the groove 2211 is a "cross" shaped groove to form two mutually perpendicular moving channels, and the two moving channels extend along the first direction L1 and the second direction L2 respectively. The second direction L2 is perpendicular to the first direction L1 and parallel to the first surface 11 (see Figure 1 The first clamping structure 222 moves along the moving channel extending along the first direction L1 to clamp or release the screen to be tested. The second clamping structure 223 moves along the moving channel extending along the second direction L2 to clamp or release the screen to be tested.

[0069] The first clamping structure 222 includes an upper clamping block 2221, a lower clamping block 2222, a first motor 2223, a first screw rod 2224, a first reverse screw rod 2225, and a first sleeve 2226. The upper clamping block 2221, the lower clamping block 2222, the first screw rod 2224, the first reverse screw rod 2225, and the first sleeve 2226 are located within the groove 2211. The first motor 2223 is connected to the side of the clamping platform 221. The first stress strain gauge 224 is connected to the surface of the lower clamping block 2222 connected to the first reverse screw rod 2225.

[0070] One end of the first screw rod 2224 is connected to the first motor 2223 and the upper clamping block 2221, and the other end is connected to the first sleeve 2226. One end of the first reverse screw rod 2225 is connected to the lower clamping block 2222, and the other end is connected to the first sleeve 2226. In other words, the first screw rod 2224 and the first reverse screw rod 2225 are respectively connected to the ends of the first sleeve 2226. The upper clamping block 2221 is located between the lower clamping block 2222 and the first motor 2223.

[0071] Driven by the first motor 2223, the first screw rod 2224 and the first reverse screw rod 2225 rotate toward the first sleeve 2226, respectively driving the upper clamping block 2221 and the lower clamping block 2222 to tighten toward the first sleeve 2226, thereby clamping the screen to be tested between the upper clamping block 2221 and the lower clamping block 2222. Alternatively, driven by the first motor 2223, the first screw rod 2224 and the first reverse screw rod 2225 rotate out from the ends of the first sleeve 2226, respectively driving the upper clamping block 2221 and the lower clamping block 2222 to gradually move away from the first sleeve 2226 at the upper and lower ends, thereby releasing the screen to be tested. The above movement process is the tightening or expansion of the first clamping structure 222 along the first direction L1.

[0072] During the tightening or expansion of the first clamping structure 222, the screen under test between the upper clamping block 2221 and the lower clamping block 2222 compresses the lower clamping block 2222, thereby compressing the first stress strain gauge 224. The first stress strain gauge 224 is used to continuously detect and feedback sensor data. The first motor 2223 drives the movement of the upper clamping block 2221 and the lower clamping block 2222 based on the sensor data fed back by the first stress strain gauge 224.

[0073] The second clamping structure 223 includes a right clamping block 2231, a left clamping block 2232, a second motor 2233, a second screw rod 2234, a second reverse screw rod 2235, and a second sleeve 2236. The right clamping block 2231, the left clamping block 2232, the second screw rod 2234, the second reverse screw rod 2235, and the second sleeve 2236 are located within the groove 2211. The second motor 2233 is connected to the side of the clamping platform 221. The second stress strain gauge 225 is connected to the surface of the left clamping block 2232 connected to the second reverse screw rod 2235.

[0074] One end of the second screw rod 2234 is connected to the second motor 2233 and the right clamping block 2231, and the other end is connected to the second sleeve 2236. One end of the second reverse screw rod 2235 is connected to the left clamping block 2232, and the other end is connected to the second sleeve 2236. In other words, the second screw rod 2234 and the second reverse screw rod 2235 are respectively connected to the two ends of the second sleeve 2236. The right clamping block 2231 is located between the left clamping block 2232 and the second motor 2233.

[0075] Driven by the second motor 2233, the second screw rod 2234 and the second reverse screw rod 2235 rotate toward the second sleeve 2236, respectively driving the right clamping block 2231 and the left clamping block 2232 to tighten toward the second sleeve 2236, thereby clamping the screen to be tested between the right clamping block 2231 and the left clamping block 2232. Alternatively, driven by the second motor 2233, the second screw rod 2234 and the second reverse screw rod 2235 rotate out from the ends of the second sleeve 2236, respectively driving the right clamping block 2231 and the left clamping block 2232 to gradually move away from the second sleeve 2236 toward the left and right ends, thereby releasing the screen to be tested. The above movement process is the tightening or expansion of the second clamping structure 223 along the second direction L2.

[0076] During the contraction or expansion of the second clamping structure 223, the screen under test between the right clamping block 2231 and the left clamping block 2232 compresses the left clamping block 2232, thereby compressing the second stress strain gauge 225. The second stress strain gauge 225 is used to continuously detect and feedback sensor data. The second motor 2233 drives the movement of the right clamping block 2231 and the left clamping block 2232 based on the sensor data fed back by the second stress strain gauge 225.

[0077] By driving the upper clamping block 2221, the lower clamping block 2222, the right clamping block 2231 and the left clamping block 2232 to move respectively along the first direction L1 and the second direction L2, the distance between the upper clamping block 2221 and the lower clamping block 2222 can be adjusted in the first direction L1, and the distance between the left clamping block 2232 and the right clamping block 2231 can be adjusted in the second direction L2, so as to adapt to clamping screens to be tested of different shapes and sizes.

[0078] The lifting assembly 23 includes a longitudinal slide rail 231, a longitudinal slider 232, a lifting motor 233, a longitudinal screw rod 234, and a longitudinal connecting block 235. The longitudinal slide rail 231 is fixedly connected to the mounting surface 2121 of the vertical plate 212. The longitudinal slide rail 231 is formed with a longitudinal track 2311 extending along the first direction L1. The longitudinal slider 232 is fixedly connected to the clamping platform 221 and slidably connected within the longitudinal track 2311. The longitudinal slider 232 is located between the longitudinal slide rail 231 and the clamping platform 221. The lifting motor 233 is connected to the surface of the turntable 211 connected to the vertical plate 212. One end of the longitudinal screw rod 234 is connected to the lifting motor 233, and the other end is sleeved with the longitudinal connecting block 235 and the clamping platform 221. The clamping platform 221 is fixedly connected to the longitudinal connecting block 235 and is located between the lifting motor 233 and the longitudinal connecting block 235. The lifting motor 233 is used to drive the clamping assembly 22 to move up and down along the longitudinal track 2311 as a whole.

[0079] Please refer to Figure 1The display detection module 30 is fixedly mounted on the base plate 10, and its detection height remains unchanged during the detection process. When the clamping assembly 22 clamps and fixes screens of different sizes to be tested, the height of the clamping assembly 22 can be adjusted by the lifting assembly 23 to ensure that the center area of ​​the screen to be tested (usually the area including the geometric center of the display surface) can adapt to the detection height of the display detection module 30.

[0080] Please refer to Figure 3 The rotating module 60 includes a rotating motor 61. The rotating motor 61 is disposed on the second surface 12 (see FIG. Figure 1 The rotary motor 61 is connected to the side of the turntable 211 away from the vertical plate 212. The rotary motor 61 is used to drive the turntable 211 to rotate about the axis L0, thereby driving the structure on the turntable 211 (including the clamping assembly 22, the lifting assembly 23, and the vertical plate 212) to rotate synchronously about the axis L0. When the structure on the turntable 211 rotates about the axis L0, the screen to be tested, which is clamped and fixed in the clamping assembly 22, swings left and right, and the angle between the screen to be tested and the display detection module 30 changes, allowing the display detection module 30 to detect the screen to be tested from different angles, thereby realizing the detection of the display performance of the screen to be tested at different angles.

[0081] In this embodiment, the display detection module 30 includes a spectrocolorimeter 31 .

[0082] See also Figure 4 The touch detection module 40 includes a first translation assembly 41, a touch assembly 42, a second translation assembly 43, a support assembly 44, and a support platform 45. The touch assembly 42 is connected to the first translation assembly 41. The support assembly 44 is connected between the first translation assembly 41 and the second translation assembly 43. The support platform 45 is fixedly connected to the first surface 11 of the base plate 10, and the second translation assembly 43 is connected to the side of the support platform 45 away from the base plate 10.

[0083] The first translation assembly 41 is used to drive the touch assembly 42 to translate along the second direction L2 to achieve the touch screen under test. The support assembly 44 is used to elevate and support the first translation assembly 41 and touch assembly 42. The second translation assembly 43 is used to drive the first translation assembly 41, touch assembly 42, and support assembly 44 to translate along the second direction L2 as a whole, to approach the screen under test or to return to the initial position.

[0084] The first translation assembly 41 includes a first transverse rail 411, a first transverse slider 412, a first translation motor 413, a first transverse screw 414, and a first transverse connecting block 415. One end of the first transverse screw 414 is connected to the first translation motor 413, and the other end is sleeved with the first transverse connecting block 415. The first transverse rail 411 is fixedly connected to the support assembly 44. The first transverse rail 411 forms a first transverse track 4111 extending along the second direction L2. The first transverse slider 412 is slidably connected within the first transverse track 4111.

[0085] The touch control assembly 42 includes a connector 421, a stylus 422, and a touch stress strain gauge 423. The stylus 422 is detachably connected to the connector 421. The touch stress strain gauge 423 is located within the connector 421 and contacts the stylus 422 to sense the stress applied to the stylus 422. The first transverse slider 412 is fixedly connected between the first transverse rail 411 and the connector 421. The connector 421 is mounted on the first transverse screw rod 414 and is located between the first translation motor 413 and the first transverse connecting block 415.

[0086] The second translation assembly 43 includes a second transverse rail 431, a second transverse slider 432, a second translation motor 433, a second transverse screw 434, and a second transverse connecting block 435. One end of the second transverse screw 434 is connected to the second translation motor 433, and the other end is sleeved with the second transverse connecting block 435. The second transverse rail 431 is fixedly connected to the support platform 45. The second transverse rail 431 forms a second transverse track 4311 extending along the second direction L2. The second transverse slider 432 is slidably connected to the second transverse track 4311.

[0087] The support assembly 44 includes a support frame 441 and a mounting platform 442. The first transverse slide rail 411 and the first translation motor 413 are fixedly connected to the side of the mounting platform 442 away from the support frame 441. The support frame 441 is fixedly connected between the mounting platform 442 and the second transverse slider 432. The support frame 441 is fixedly connected to the second transverse slider 432 and is sleeved on the second transverse screw rod 434.

[0088] Please also refer to Figure 4 and Figure 5 The first translation assembly 41 and / or the second translation assembly 43 drive the touch assembly 42 to translate along the second direction L2, thereby controlling the stylus 422 to move closer to or further away from the clamping module 20. When the touch performance of the screen to be tested needs to be tested, the rotary motor drives the turntable 211 to rotate 90° clockwise about the axis L0, thereby driving the entire clamping module 20 to rotate 90° clockwise about the axis L0. This causes the screen to be tested, which is clamped and fixed in the clamping module 20, to face the stylus 422, allowing the stylus 422 to touch the surface of the screen to be tested.

[0089] Please refer to Figure 1 In this embodiment, the screen detection device 1 further includes a control module 50 connected to the base plate 10. The control module 50 is electrically connected to the clamping module 20, the display detection module 30, and the touch detection module 40, respectively, and is used to control the working processes of the clamping module 20, the display detection module 30, and the touch detection module 40.

[0090] The control module 50 includes a host computer 51 and a human-computer interaction screen 52, which are electrically connected to each other. The host computer 51 is located within the base plate 10. The human-computer interaction screen 52 is fixedly connected to the first surface 11 and is electrically connected to and used to control the first motor 2223, the second motor 2233, the lifting motor 233, the rotating motor 241, the first translation motor 413, the second translation motor 433, and the spectrophotometer 31. The display detection module 30 is located between the human-computer interaction screen 52 and the clamping module 20. The host computer 51 is used to output control signals. The human-computer interaction screen 52 has integrated display and touch functions, and is used to display operating information and receive test parameters input by the user.

[0091] In this embodiment, the base plate 10 further has a side surface 13 connected between the first surface 11 and the second surface 12. A communication interface 131 (a USB interface in this embodiment) is formed on the side surface 13 for transmitting test data to an external device (such as a computer or other smart terminal) to facilitate subsequent storage, analysis, and display of the test data.

[0092] The following combination Figure 1-Figure 5 The working process of the screen detection device 1 in the embodiment of the present application is described.

[0093] The screen to be tested is placed in the clamping assembly 22 . The screen to be tested presses down the clamping block 2222 due to gravity. At this time, the first stress strain gauge 224 generates a sensing signal.

[0094] After receiving the sensing signal fed back by the first stress strain gauge 224, the host 51 controls the first motor 2223 to drive the upper clamping block 2221 and the lower clamping block 2222 to retract toward the first sleeve 2226 to clamp the screen to be tested in the up and down directions (first direction L1), and at the same time controls the second motor 2233 to drive the left clamping block 2232 and the right clamping block 2231 to retract toward the second sleeve 2236 to clamp the screen to be tested in the left and right directions (second direction L2).

[0095] As the upper clamping block 2221, the lower clamping block 2222, the left clamping block 2232, and the right clamping block 2231 clamp the screen to be tested, the first stress strain gauge 224 and the second stress strain gauge 225 are squeezed and continuously output sensing signals to the host 51. When the host 51 determines that the current sensing signal reaches a preset threshold, it controls the first motor 2223 and the second motor 2233 to stop driving the clamping process.

[0096] After the screen to be tested is clamped, the host 51 calculates the size of the screen to be tested and controls the lifting motor 233 to drive the clamping assembly 22 to move to a corresponding height so that the spectrocolorimeter 31 can detect the central area of ​​the screen to be tested.

[0097] The user can adjust and set test parameters (including test items, compensation values, etc.) through the human-computer interaction screen 52 and click the start test button. The host 51 controls the spectrocolorimeter 31 to test the display performance of the screen to be tested according to the set test parameters.

[0098] During the testing process of the spectrocolorimeter 31 , the host 51 also controls the rotary motor 241 to drive the turntable 211 to rotate around the axis L0 , changing the placement angle of the screen to be tested, so that the spectrocolorimeter 31 can detect the display performance of the screen to be tested from different angles.

[0099] If the screen to be tested is a touch screen or a display screen with integrated touch function, the host 51 further controls the rotary motor 241 to drive the turntable 211 to rotate 90° clockwise around the axis L0 so that the screen to be tested faces the touch detection module 40 .

[0100] The host 51 controls the second translation motor 433 to move forward (i.e., translate toward the clamping module 20). When the stylus 422 touches the screen to be tested, the touch stress strain gauge 423 generates a sensing signal and feeds it back to the host 51. The host 51 determines whether the touch force of the stylus 422 is consistent with the set force. If consistent, the first translation motor 413 stops waiting. After waiting for 3 seconds, the first translation motor 413 drives the stylus 422 to translate back and forth (when the sensing signal feedback from the touch stress strain gauge 423 is 0, it stops retracting and starts moving forward; when the sensing signal feedback from the touch stress strain gauge 423 reaches a preset threshold, it stops moving forward and starts retracting) to touch the screen to be tested multiple times until the number of touches reaches the preset number and stops.

[0101] After the touch detection module 40 stops testing, the host 51 controls the second translation motor 433 to return to the initial position, and controls the clamping module 20 to rotate to the initial position.

[0102] The detection data generated by the display detection module 30 and the touch detection module 40 are transmitted to the host 51 , and the host 51 outputs the detection data to an external terminal device through the communication interface 131 .

[0103] The screen detection device 1 of the embodiment of the present application includes a clamping module 20, and the clamping module 20 includes a first clamping structure 222 and a second clamping structure 223. The first clamping structure 222 and the second clamping structure 223 are used to clamp or release the screen to be tested in two vertical directions respectively, so that the clamping module 20 can clamp screens to be tested of different sizes, which is beneficial to improving the universality of the screen detection device 1, so that the screen detection device 1 can be recycled for different screens to be tested, and can also be used for incoming material inspection of the production line after mass production.

[0104] In addition, the screen detection device 1 also includes a display detection module 30 and a touch detection module 40, realizing the integration of display detection and touch detection, and at the same time meeting the color reproduction test, brightness uniformity test, color uniformity test, white balance test, signal-to-noise ratio test, test click aging test, making the screen detection device 1 as a whole multifunctional.

[0105] Furthermore, the screen detection device 1 has a simple overall installation method, is easy to operate, and has a high overall degree of automation, which is conducive to reducing manpower, material resources and time.

[0106] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not used to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of protection claimed in the present application.
