[0045] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0046] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0047] Combination Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides a whole-machine color calibration device, which includes a test mechanism 1 and a placement mechanism 2; the test mechanism 1 has a test probe 11, and a driving component 12 for driving the test probe 11 to move at least in the up and down and front and back directions; the placement mechanism 2 includes a disc carrier 21 for clamping and placing the whole machine to be tested, and an angle detector 22 for detecting the opening and closing angle of the whole machine screen; the test mechanism 1 also includes a distance measuring piece 13 arranged flush with the test probe 11; the distance measuring piece 13 can move synchronously with the test probe 11, and measure the real-time distance between the test probe 11 and the whole machine screen.

[0048] The whole machine color calibration device can be specifically but not limited to being applied to the color calibration of the screen in a laptop computer, the color calibration of the screen in a foldable mobile phone, and other scenarios. Specifically, the color calibration of the laptop computer screen is taken as an example to illustrate its use.

[0049] When the whole machine color calibration device is used, the laptop computer to be tested is first opened to a preset angle (for example, the screen can be opened to a 90° angle with the body), and then the body is clamped and placed on the disc carrier 21 in the placement mechanism 2. At this time, the angle detector 22 in the placement mechanism 2 can detect whether the opening and closing angle of the screen meets the error value with the preset angle. After the detection is met, the test probe 11 in the test mechanism 1 can be driven by the drive component 12 to move in the up and down and front and back directions until the test probe 11 is completely and vertically attached to the screen. Then the color calibration unit in the test probe 11 can collect the screen color and perform color △E value verification.

[0050] Moreover, when the test probe 11 is moving, the distance measuring component 13 can move synchronously with it and measure the real-time distance between the test probe 11 and the screen at all times, thereby avoiding collision between the test probe 11 and the screen.

[0051] In summary, the whole-machine color calibration device provided in the embodiment of the present disclosure can ensure that the opening and closing angle of the screen to be tested meets the error value with the preset angle through the angle detector 22; it can ensure that the test probe 11 can be completely and safely attached to the screen under the drive of the driving component 12 through the test probe 11 and the distance measuring component 13 in the testing mechanism 1, thereby ensuring the accuracy of the screen color acquisition, and can fully achieve an excellent calibration result of color △E value ≤ 1.0.

[0052] In one embodiment, the driving assembly 12 includes a lifting frame 121 and a sliding frame 122; the lifting frame 121 includes two supporting legs that can be extended and retracted in the up and down directions, and a transverse frame connecting the two supporting legs; the sliding frame 122 is vertically fixed to the transverse frame along the front and back directions; wherein the ranging component 13 and the test probe 11 are respectively installed on the sliding frame 122 through the driving motor, and can slide back and forth along the sliding frame 122.

[0053] Specific, combined Figure 2 To further explain in detail, the driving component 12 is specifically configured to include a lifting frame 121 and a sliding frame 122, and the lifting frame 121 can be lifted and lowered in a manner that its own supporting legs are retracted in the up and down directions, the ranging component 13 and the test probe 11 are respectively installed on the sliding frame 122 through the driving motor, and can slide back and forth along the sliding frame 122, so that the driving component 12 can drive the test probe 11 to move in the up and down and front and back directions.

[0054] Moreover, in order to ensure the precise controllability of the moving position of the test probe 11, the telescopic lifting and retracting method of the supporting tripod in the lifting frame 121 can be realized by means of a "stepping motor + screw nut transmission mechanism", and the distance measuring component 13 and the test probe 11 can be installed on the sliding frame 122 by means of a "linear motor" or a "stepping motor + gear rack transmission mechanism", and the output stepping angle of the stepping motor or the output straight-line distance of the linear motor can be correspondingly adjusted by a PLC controller.

[0055] Moreover, in order to further detect the actual height of the lifting frame 121 in real time, an infrared ranging sensor may be disposed downward in the lifting frame 121 to detect the actual lifting height of the lifting frame 121 in real time.

[0056] Of course, the driving component 12 may also be configured in other forms, such as but not limited to being configured as a spatial multi-degree-of-freedom manipulator to correspondingly drive the test probe 11 to move in the up-down and forward-backward directions.

[0057] The specific configuration of the driving assembly 12 has a simple structure, low engineering cost, and can accurately control the up-down and front-back positions of the test probe 11 .

[0058] In one possible implementation manner, the detection end of the test probe 11 is provided with an elastic light shielding sleeve 111 ; the front end of the distance measuring component 13 is provided with an elastic buffer pad 131 .

[0059] Specific, combined Figure 2To further explain in detail, an elastic light-shielding sleeve 111 is provided at the detection end of the test probe 11. The elastic light-shielding sleeve 111 can be specifically but not limited to a rubber sleeve with a central opening, so that when the test probe 11 is completely and vertically attached to the screen, the elastic light-shielding sleeve 111 can completely cover and isolate the outer wall of the test probe 11, so that only the color light emitted by the screen can be collected by the test probe 11, avoiding the influence of external ambient light on the screen color calibration.

[0060] In addition, an elastic buffer pad 131 is provided at the front end of the distance measuring member 13, so as to prevent the distance measuring member 13 from causing bumps and wear on the screen when it moves synchronously with the test probe 11. The elastic buffer pad 131 can also be set to rubber or EVA plastic material.

[0061] In one embodiment, the carrier 21 includes a clamping opening and closing cylinder 211 for clamping the whole machine to be tested in the front-to-back direction, and a center clamping device 212 for clamping the whole machine to be tested in the left-to-right direction.

[0062] Specific, combined Figure 3 In further detail, the clamping opening and closing cylinder 211 can clamp the whole machine to be tested in the front-to-back direction by moving them toward each other, and the centering clamping device 212 can clamp the whole machine to be tested in the left-right direction. When the whole machine to be tested is placed in the carrier 21, the centering clamping device 212 is used to center the whole machine to be tested in the left-right direction, and then the clamping opening and closing cylinder 211 is controlled to finally fix the whole machine to be tested in the left-right direction, so that the placement firmness and positioning accuracy of the whole machine to be tested in the carrier 21 can be fully ensured.

[0063] Moreover, the above-mentioned centering clamping device 212 can be specifically configured as two L-shaped clamping plates facing each other, and the two are connected to each other through elastic members of equal length and equal elastic coefficient, so that the two L-shaped clamping plates can clamp the entire machine to be tested in the center under the action of the equal elastic force of the elastic members.

[0064] In one embodiment, the angle detector 22 includes an angle limit plate 221 and an angle sensor 222; the angle limit plate 221 is vertically arranged on the carrier seat 21, and one side of the plate surface can abut against the back side of the whole screen; the angle sensor 222 is arranged in the plate surface of the angle limit plate 221 facing the back side of the whole screen, and can detect the angle formed by the angle limit plate 221 and the back side of the whole screen.

[0065] Specific, combined Figure 3 and Figure 4To further explain in detail, the above-mentioned angle limit plates 221 can be specifically arranged with two parallel intervals, and an angle sensor 222 is respectively arranged in the plate surface of the angle limit plate 221 facing the back side of the screen of the whole machine, so that when the whole machine to be tested is placed and fixed in the carrier seat 21, the angle limit plate 221 can abut against the back side plate surface of the opened screen. If the screen is not fully opened to 90°, a wedge-shaped gap can be formed between the back side plate surface of the screen and the angle limit plate 221, so that the angle sensor 222 can obtain the actual gap angle between the two by detecting the size of the gap between the two.

[0066] Of course, if the angle detector 22 detects that the screen angle is less than 90° and exceeds the error, the angle detector 22 can also set an alarm prompt accordingly so that the staff can adjust the opening angle of the screen in time.

[0067] In one embodiment, the placement mechanism 2 also includes a screen angle correction mechanism 23; the screen angle correction mechanism 23 is correspondingly arranged on one side of the carrier 21 close to the whole machine screen; the screen angle correction mechanism 23 can correct and adjust the opening and closing angle of the whole machine screen according to the detection result of the angle detector 22.

[0068] Specific, combined Figure 2 To further explain in detail, a screen angle correction mechanism 23 is arranged on the side of the disc carrier 21 close to the screen of the whole machine, so that when the angle detector 22 detects that the opening angle of the screen exceeds the error, the screen angle correction mechanism 23 can be controlled to work accordingly, and the screen angle correction mechanism 23 can correct and adjust the opening angle of the screen accordingly, so that the opening angle of the screen can meet the optimal requirements of the test organization 1 for color calibration.

[0069] In one embodiment, the screen angle correction mechanism 23 includes a butt joint 231 and a translation drive mechanism 232; the butt joint 231 is configured as a cylindrical rolling body that can roll and abut against the back side of the entire screen; the translation drive mechanism 232 can drive the butt joint 231 to move back and forth along the front-to-back direction toward or away from the back side of the entire screen.

[0070] Specific, combined Figure 2 To further explain in detail, the screen angle correction mechanism 23 is specifically configured to include a butt joint 231 and a translation drive mechanism 232, and the translation drive mechanism 232 can drive the butt joint 231 to move back and forth along the front-to-back direction toward or away from the back side of the entire screen, so that the butt joint 231 can correspondingly butt against the screen to achieve the function of correcting and adjusting the opening angle of the screen.

[0071] Moreover, the abutment joint 231 is configured as a cylindrical rolling body that can roll and abut against the back side of the screen, so that when the opening angle of the screen is greater than 90°, the abutment joint 231 can be driven by the translation drive mechanism 232 to move toward the back side of the screen to press, and the abutment joint 231 can roll along the back side of the screen to prevent the back side of the screen from being bumped and scratched when pressing against the back side of the screen; in this way, when the opening angle of the screen is less than 90°, the test probe 11 and the distance measuring part 13 can be driven by the drive component 12 to completely press against the screen, at this time the opening angle of the screen will gradually increase, and when it reaches 90°, the back side of the screen will abut against the abutment joint 231, thereby realizing that the opening angle of the screen is limited to 90°, and the abutment joint 231 and the test probe 11 are jointly limited on the front and back sides of the screen to prevent the screen from being excessively opened.

[0072] In one embodiment, the whole-machine color calibration device also includes a conveying mechanism 3; the conveying mechanism includes an input buffer unit 31, a loading unit 32, a detection and calibration unit 33, a unloading unit 34 and an output buffer unit 35 which are arranged in sequence through a conveyor belt; wherein the screen angle correction mechanism 23 is correspondingly arranged in the loading unit 32.

[0073] Specific, combined Figure 5 To further explain in detail, the conveyor belt in the conveying mechanism can specifically adopt segmented conveying, and trays for temporarily storing the whole machine to be tested can be respectively arranged in the conveyor belt, and clamps for transferring the whole machine to be tested can be sequentially arranged between the feeding buffer unit 31, the loading unit 32, the detection and calibration unit 33, the unloading unit 34 and the discharging buffer unit 35, and the transfer of the whole machine to be tested between the various units can be realized by moving the clamps along the three-dimensional direction.

[0074] Furthermore, when the whole machine to be tested is color calibrated in the detection and calibration unit, the brightness side door of the body shell in the detection and calibration unit 33 can be switched from open to closed accordingly, so as to further avoid the influence of light in the external environment on the screen color calibration.

[0075] In addition, a QR code scanner can be provided in the detection and calibration unit 33 to scan and read the model type of the whole machine to be tested, and burn the color calibration value and color brightness calibration burning of the computer through the burning device according to the model type.

[0076] Moreover, the material input buffer unit 31, the material loading unit 32, the detection and calibration unit 33, the material unloading unit 34 and the material output buffer unit 35 can all use a PLC control unit to communicate with the industrial computer and connect to the MES system through a server to ensure coordinated operation of each unit.

[0077] In one possible implementation, the detection and calibration unit 33 has a plurality of placement mechanisms 2 , and the plurality of placement mechanisms 2 are respectively provided with a testing mechanism 1 in one-to-one correspondence; the plurality of placement mechanisms 2 form a plurality of detection lines along different heights in the detection and calibration unit.

[0078] Specific, combined Figure 5 To further explain in detail, a plurality of placing mechanisms 2 are arranged in the detection and calibration unit, and the plurality of placing mechanisms 2 are respectively provided with testing mechanisms 1 in one-to-one correspondence, and a plurality of detection lines are formed along different heights in the detection and calibration unit, so that a plurality of complete machines to be tested can be transported from the loading unit, and after being placed in the corresponding placing mechanisms 2 in the plurality of detection lines of the detection and calibration unit, the side door of the machine body shell in the detection and calibration unit is closed, and color calibration is performed on the plurality of complete machines to be tested at the same time, thereby greatly improving the working efficiency in the detection and calibration unit.

[0079] In one possible implementation manner, the loading unit 32 and the unloading unit 34 are respectively provided with transport clamps; the transport clamps can clamp and move the whole machine to be tested along a three-dimensional space coordinate system.

[0080] Specific, combined Figure 5 To further explain in detail, the transporting jaws in the loading unit 34 and the unloading unit 34 can specifically adopt cylinder jaws, and the transporting jaws can specifically be set by a lifting platform, so that the transporting jaws can at least realize up and down lifting and forward and backward telescopic movements, which can fully realize the clamping and moving transport function requirements of the whole machine to be tested.

[0081] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0082] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
