[0040] The embodiment of the present invention provides an optical data detection device 1, which is used for optical data detection of some special display devices such as displays and advertising machines.

[0041] like Figure 1-Figure 10 As shown, the optical data detection device 1 includes a light sensor 11, a test arm 12, a motor 13, a fixed guide 14, a screw sleeve 15, a guide screw 16 and a movable part 17. The guide screw 16 is arranged in the fixed guide 14, one end of the guide screw 16 is connected to the output shaft of the motor 13, the screw sleeve 15 and the movable part 17 are movably sleeved on the guide screw 16, and the screw sleeve 15 is located below the movable part 17, the screw sleeve 15 is threadedly connected to the guide screw 16, the test arm 12 is connected to the movable part 17, the light sensor 11 is arranged on the test arm 12, the fixed guide 14 is provided with a guide groove 141, the movable part 17 is provided with a first moving part 1711, the screw sleeve 15 is provided with a second moving part 151, the first moving part 1711 and the second moving part 151 are both embedded in the guide groove 141; when the first moving part 1711 moves along the guide groove 141, the lifting and rotating movements of the test arm 12 are realized.

[0042] Specifically, the motor 13 can be a servo motor 13 or a stepper motor 13, etc. The fixed guide member 14 is a cylindrical structure with open ends at the upper and lower ends. The guide screw 16 is located in the fixed guide member 14. The guide screw 16 is provided with an external thread near its lower end. The guide screw 16 is connected to the internal thread of the screw sleeve 15 by its external thread. The bottom of the guide screw 16 is fixedly connected to the output shaft of the motor 13. When the motor 13 is working, it drives the guide screw 16 to rotate. Since the second moving part 151 of the screw sleeve 15 is in the guide groove 141, the screw sleeve 15 makes a linear motion in the guide screw 16, thereby pushing the movable part 17. The first motion of the movable part 17 moves along the guide groove 141, so that the movable part 17 can adjust the height and rotation angle, thereby realizing the lifting and rotation of the test arm 12. When the display screen needs to be tested, the test arm 12 is extended to the test position of the display area to test the display screen, and then returned to the test device after the test is completed, so as not to affect the screen display. At the same time, it ensures that the test can be fixed in the same position each time, thereby ensuring the accuracy of the test results.

[0043] It should be noted that an optical sensor is a sensor that obtains corresponding information by detecting (collecting), converting or transforming light signals. It is mainly composed of detectors, driving components and output components. It detects light signals, converts them into electrical signals, and then outputs meaningful signals to meet user needs. For example: it is used to detect the luminous intensity of a certain luminous surface, the color (color temperature) of light, etc. Optical sensors are standard parts that can be purchased on the market, so they will not be described in detail.

[0044] like Figure 3 As shown, a mounting cavity is provided between the movable part 17 and the guide screw rod 16, and a spring 161 is provided in the mounting cavity. When the spring 161 is subjected to the extrusion force of the movable part 17, one end of the spring 161 abuts against the movable part 17, and the other end of the spring 161 abuts against the guide screw rod 16. The spring 161 and the screw rod sleeve 15 together provide power for the autonomous movement of the movable part 17.

[0045] like Figure 1 As shown, in one embodiment, the top of the guide screw rod 16 is connected with a pressing sleeve 162 by screws. The pressing sleeve 162 is mainly used to form a match with the spring 161. When the spring 161 is subjected to a squeezing force, the upper end of the spring 161 abuts against the pressing sleeve 162, and the lower end of the spring 161 abuts against the movable part 17. With such a design, when the spring 161 is subjected to a squeezing force, the upper end abuts against the pressing sleeve 162, and the lower end abuts against the movable part 17. This design ensures that the elastic force of the spring 161 can be effectively transmitted to the movable part 17, thereby providing the necessary return force and buffer force, so that the movable part 17 can smoothly return to the initial position or achieve a specific movement.

[0046] like Figure 4-Figure 5 As shown, the guide groove 141 includes a first vertical groove 1411, a second vertical groove 1412 and a V-shaped groove 1413, wherein the V-shaped groove 1413 is disposed between the first vertical groove 1411 and the second vertical groove 1412, wherein one end of the V-shaped groove 1413 is connected to the upper end of the first vertical groove 1411, and the other end of the V-shaped groove 1413 is connected to the upper end of the second vertical groove 1412. With such a design, the movable member 17 can rotate while performing the lifting and rotating motions, so as to meet the lifting and rotating motion requirements of the test arm 12.

[0047] Specifically, the first moving part 1711 and the second moving part 151 are located in the first vertical groove of the guide groove 141, that is, Figure 4When the motor 13 rotates forward, it drives the guide screw 16 to rotate, and the screw sleeve 15 moves upward under the action of the guide screw 16, thereby pushing the movable member 17 to slide upward along the guide screw 16. During this process, the first moving part 1711 and the second moving part 151 are displaced upward, but are still in the first vertical groove, that is, Figure 5 The test arm 12 moves upward relative to the initial position. When the motor 13 continues to rotate forward to drive the guide screw 16 to rotate, the screw sleeve 15 continues to move upward under the action of the guide screw 16, thereby pushing the movable member 17 to continue to move upward. During this process, the second moving part 151 moves to the highest point of the first vertical groove, and at the same time, the first moving part 1711 moves along the rising section of the V-shaped groove 1413 to the highest point of the V-shaped groove 1413, that is, Figure 6 The test arm 12 is in the position shown, at this time, it has risen to the maximum height relative to the initial position and has rotated at an angle. Next, the motor 13 rotates in the opposite direction to drive the guide screw 16 to rotate in the opposite direction, and the screw sleeve 15 moves downward under the action of the guide screw 16. The movable member 17 moves downward along the guide screw 16 under the pressure of the spring 161. During this process, the second moving part 151 moves downward from the highest point of the first vertical groove, and the first moving part 1711 moves along the descending section of the V-shaped groove 1413 to the lowest point of the V-shaped groove 1413, that is, Figure 7 The test arm 12 is rotated to the detection position. Then the motor 13 continues to rotate in the reverse direction to drive the guide screw 16 to continue to rotate in the reverse direction. The screw sleeve 15 continues to move downward under the action of the guide screw 16. The movable member 17 continues to move downward along the guide screw 16 under the pressure of the spring 161. During this process, the second moving part 151 drops to the lowest point of the first vertical groove, that is, it returns to the initial position of the second moving part 151, and the first moving part 1711 enters the second vertical groove 1412 from the lowest point of the V-shaped groove 1413 and moves downward. Figure 8 As shown in the position, the test arm 12 descends to reach the detection position (the descent of the test arm 12 ensures that the light sensor 11 is relatively close to the display screen to prevent external light from affecting the accuracy of the test data), and then the detection work can begin.

[0048] It can be understood that the movement process of the test arm 12 described above can be summarized as follows: the test arm 12 first rises from the initial position in the first stage, then rises in the second stage while rotating in the first stage, then descends in the first stage while rotating in the second stage (in the same direction as the rotation in the first stage), and finally descends in the second stage to reach the detection position. When the detection task is completed, the above-mentioned actions are reversed to return the test arm 12 to the initial position.

[0049] Through the above design, the test arm 12 can be accurately positioned at the detection position, ensuring that the position and angle of each detection are consistent. At the same time, the test arm 12 can be raised and lowered and rotated in a relatively compact space, optimizing the space utilization of the device. When not in operation, the test arm 12 can return to the initial position without affecting the normal display of the display.

[0050] like Figure 1 As shown, the movable member 17 includes a sleeve portion 171 and a support plate 172. The support plate 172 is horizontally extended outward along one side of the sleeve portion 171. The sleeve portion 171 is sleeved on the guide screw rod 16. The test arm 12 is fixedly connected to the support plate 172. Such a design can effectively utilize space, facilitate the installation of the test arm 12, and provide a stable support force for the test arm 12.

[0051] Specifically, a boss is provided inside the sleeve portion 171 , and the boss is used to support the spring 161 and facilitate forming an abutting relationship with the bottom of the spring 161 .

[0052] like Figure 1 , Figure 3 As shown, the optical data detection device 1 further includes a bracket 18, the fixed guide 14 is fixedly connected to the bracket 18, and the motor 13 is installed on the bracket 18. The bracket 18 can be a plate-like structure or other structures, and there is no specific limitation on it.

[0053] Specifically, the fixed guide member 14 is fixedly connected to the bracket 18 to ensure that the guide member remains stable during operation and will not be displaced or loosened due to vibration or other external forces. The motor 13 is installed on the bracket 18 to also improve the stability of the motor 13, ensuring that the normal operation of the device will not be affected by vibration during operation.

[0054] like Figure 1 , Figure 3 As shown, the optical data detection device 1 further includes a housing 19, the bracket 18 is disposed in the housing 19, a through hole and a storage groove 1921 are disposed on the top of the housing 19, the sleeve portion 171 is inserted into the through hole, and in the storage state, the test arm 12 is located in the storage groove 1921. Such a design allows the sleeve portion 171 to be inserted into the through hole, and in the storage state, the test arm 12 is stored in the storage groove 1921, which optimizes space utilization, makes the device more compact when not in use, and is also convenient for storage and transportation.

[0055] Specifically, the shell 19 includes an upper shell portion 192 and a lower shell portion 191, and the upper shell portion 192 and the lower shell portion 191 are fixedly connected by connecting parts such as screws or by snap-fitting. After the upper shell portion 192 and the lower shell portion 191 are connected, a cavity is formed, and the bracket 18 is fixedly installed in the cavity.

[0056] The design of the housing 19 provides a closed environment, effectively protecting the internal bracket 18, motor 13 and other components from being affected by the external environment. At the same time, the housing 19 can serve as a support carrier for the entire device, making it easy to install on the display, simplifying the difficulty and complexity of installation.

[0057] like Figure 1-Figure 2 As shown, a limiting opening 1922 is provided on one side of the receiving slot 1921 , and the test arm 12 is located in the limiting opening 1922 when in working state.

[0058] Specifically, the design of the limit opening 1922 can effectively control the swinging problem of the test arm 12 when working, thereby helping to maintain the stability and precision of the test arm 12 and ensure the accuracy of the test results.

[0059] like Figure 1-Figure 3 As shown, in one embodiment, the test arm 12 is provided with an arm cover 121, which is fixed to and covers the upper surface and side surface of the test arm 12. Such a design can protect the test arm 12, prevent damage caused by mechanical collision, and increase the service life.

[0060] like Figure 1-Figure 2 As shown, the optical data detection device 1 also includes a control circuit board 193, which is arranged in the shell 19. The control circuit board 193 is provided with a data line 1932 and a power line 1931. The light sensor 11 is connected to the control circuit board 193 through the flexible data line 1932. The data measured by the light sensor 11 is transmitted to the control circuit board through the flexible data line 1932, and the result is transmitted to the data collection device through the data transmission line. The power line 1931 is used to power the device.

[0061] The embodiment of the present invention further provides a display, including a display body 2 and the above-mentioned optical data detection device 1 , wherein the optical data detection device 1 is installed on the display body 2 .

[0062] Specifically, the optical data detection device 1 can be installed at the bottom, top or side of the display body 2, and can be fixed to the display body 2 by means of screws or other connectors or by means of a snap-on connection. Fig. 9 In this state, the test arm 12 is located outside the display area of ​​the display body 2 and does not affect the screen display. Fig.10 In the state shown, the test arm 12 reaches the detection position and performs image detection.

[0063] The embodiment of the present invention further provides an optical detection method of an optical data detection device 1 , which is applied to a display and includes the following steps: S10 - S30 .

[0064] S10 . When it is necessary to detect the brightness and display color temperature of the display screen, the test arm 12 is controlled to move from the initial position to the detection position so that the test arm 12 directly detects the display area of ​​the display.

[0065] S20, transmitting the detection results to a data collection device.

[0066] S30 , when the detection is completed, the test arm 12 is controlled to leave the display area of ​​the display and return to the initial position.

[0067] For steps S10-S30, when it is necessary to detect the brightness and color temperature of the display, the user inputs a detection instruction through a control interface (such as a computer or a control panel). After receiving the instruction, the control system sends a signal to start the motor 13. After receiving the control signal, the motor 13 starts to drive the test arm 12 from the initial position to the detection position. When the test arm 12 arrives at the predetermined detection position, the optical sensor is ready to start detecting the brightness and color temperature of the display. The optical sensor sends the collected data to a data collection device via a data line 1932, and the data collection device can be a computer or a server, etc. When the light sensor 11 completes the detection task, the control test arm 12 is reset.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
