[0023] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0024] The use of terms such as "first," "second," and similar terms in the specific description does not indicate any order, quantity, or importance, but is merely used to distinguish different components. Furthermore, in the description of this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application.

[0025] It should be noted that, unless otherwise specified, the embodiments of this application and the features in different embodiments can be combined with each other.

[0026] Figure 1 This is a schematic diagram of the mobile device according to this application with the display panel located at the initial shooting position. Figure 1 As shown, this application provides a moving device 100 for a display panel 200. The moving device 100 for the display panel 200 includes at least a motor assembly 110 and a transfer platform 120. The motor assembly 110 includes a stator extending along a first direction X, a slide rail fixedly connected to the stator, and a mover connected to the slide rail. The slide rail extends along the first direction X. The transfer platform 120 is fixedly connected to the mover. The transfer platform 120 includes a platform body and a plurality of adsorption units disposed on the upper surface of the platform body. The display panel 200 is adsorbed onto the plurality of adsorption units.

[0027] Specifically, the first direction X can be any horizontal direction, so that the display panel 200 can move horizontally. Alternatively, the first direction X can also be a direction that forms an angle with the horizontal plane, so that the display panel 200 can move in any direction. This application does not limit this.

[0028] The stator can be fixedly installed on a foundation structure (such as the ground, frame, or platform). The core function of the stator is to generate an electromagnetic field to drive the movement of the mover. When energized, the stator can generate a moving electromagnetic field (such as a traveling wave magnetic field) or a changing electromagnetic field (such as a pulsating magnetic field), thereby providing electromagnetic thrust or pull to the mover and driving the stator's motion state, such as its speed and position.

[0029] The core function of the slide rail is to provide mechanical guidance and load-bearing for the mover. The slide rail can be a ball bearing linear guide or an air bearing guide, etc. The slide rail can be a linear guide extending along a first direction X, or it can be a partially curved guide. The slide rail can also have a linear guide section longer than 200 mm of the display panel; this application does not limit this. The slide rail can include two parallel tracks to facilitate sliding connection between the mover and the slide rail, and to facilitate movement of the mover on the slide rail.

[0030] The mover is slidably connected to the slide rail and can move along the slide rail. The mover can "ride" or "suspend" on or between the slide rail via bearings or sliders, thereby driving the transfer platform 120 to move along the slide rail. The mover can be located above or parallel to the stator, and is equipped with electromagnetic components corresponding to the stator, so that it can receive drive from the stator.

[0031] The transfer platform 120 is used to transport the display panel 200 and prevent displacement of the display panel 200 during its movement. The transfer platform 120 is fixedly connected to the mover, thereby enabling the display panel 200 to move along the slide rail. The transfer platform 120 may have the ability to adsorb the display panel 200, which is achieved through multiple adsorption units in the platform body. Specifically, each adsorption unit can be individually controlled to adsorb onto the display panel 200. Multiple adsorption units can be arranged in an array and located on the same plane to prevent deformation of the display panel 200 after being adsorbed by the adsorption units.

[0032] This application sets up a transfer platform 120 to support the display panel 200, and uses multiple adsorption units on the upper surface of the platform body of the transfer platform 120 to adsorb the display panel 200, thereby ensuring the display panel 200 is fixed to the transfer platform 120 and preventing the display panel 200 from shifting during movement. At the same time, a motor assembly 110 is set up, and the mover connected to the motor assembly 110 on the slide rail is fixedly connected to the transfer platform 120, so that the transfer platform 120 can move along the first direction X on the slide rail of the motor assembly 110 under the joint drive of the stator and the mover of the motor assembly 110. Compared with the manual movement of the display panel 200 in the prior art, this application can significantly improve the movement efficiency of the display panel 200.

[0033] Furthermore, the display panel 200 moved by the moving device 100 of the display panel 200 provided in this application may include a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) panel, a micro-light-emitting diode (Micro-Light Emitting Diode) panel, etc., and this application does not impose any limitations on it.

[0034] In some embodiments, the transfer platform 120 further includes a vacuum generating system. The vacuum generating system is disposed on the platform body and includes a vacuum pump and vacuum pipes. The vacuum pump is connected to each adsorption unit via the vacuum pipes. Specifically, the vacuum generating system can be fixed to the side or bottom of the platform body using a mounting base. The vacuum pipes can be tree-shaped, for example, including a main pipe, multiple branch pipes, and multiple capillary pipes interconnected. Each capillary pipe is connected to an adsorption unit to control the adsorption of the adsorption unit onto the display panel 200. The vacuum pump can be connected to the main pipe to simultaneously control all capillary pipes, or there can be multiple vacuum pumps, with one vacuum pump controlling multiple capillary pipes, or the number of vacuum pumps is the same as the number of capillary pipes, with each vacuum pump controlling one capillary pipe. This application is not limited to these limitations. The length of the vacuum pipe between each vacuum pump and each adsorption unit controlled by that vacuum pump (which can be the sum of the lengths of the interconnected main pipe, any branch pipe, and any capillary pipe) can be less than or equal to 1.5 m to reduce the vacuum response delay of the adsorption unit to the vacuum pump.

[0035] In some embodiments, continue to refer to Figure 1 The moving device 100 of the display panel 200 also includes a camera 130. The camera 130 is located on one side of the motor assembly 110. A transfer platform 120 is located between the camera 130 and the motor assembly 110 along the second direction Y. The second direction Y is vertical. The display panel 200 is positioned on opposite sides along the first direction X within the field of view of the camera 130, and / or, the display panel 200 is positioned on opposite sides along a third direction Z within the field of view of the camera 130, where the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y.

[0036] It should be noted that during the manufacturing process of the display panel 200, its dimensions need to be measured to ensure that they meet the manufacturing requirements. In existing technology, the dimensions of the display panel are typically measured manually using measuring tools. After the measurement is completed, the display panel must be manually placed back into the tray before the next panel is measured manually. This method is not only time-consuming, but the measurement accuracy also varies depending on the operator.

[0037] This application uses a camera 130 to measure the dimensions of the display panel 200. The camera can be a high-precision scanning camera 130 or an electron microscope, etc., and this application is not limited in this regard. The camera 130 can be located above, diagonally above, to the side in the horizontal direction, or below or diagonally below the vertical direction of the motor assembly 110, etc., and this application is not limited in this regard. For example, this application... Figure 1Taking the camera 130 as an example, located vertically above the motor assembly 110. In some alternative embodiments, the second direction Y can also be a direction at an acute angle to the horizontal plane or a direction parallel to the horizontal plane. The third direction Z can also be any direction parallel to the horizontal plane and intersecting the first direction X, to be applicable to parallelogram-shaped display panels 200, or display panels 200 of other shapes or irregular shapes. Furthermore, since the camera 130 has high shooting accuracy and a small field of view (e.g., 2-3 mm), it cannot cover the entire display panel 200. Therefore, in order to measure the size of the display panel 200, i.e., its length or width, it is necessary to ensure that the edges of the display panel 200 are respectively within the shooting field of view of the camera 130. Without loss of generality, assuming that the display panel 200 is along the length direction of the first direction X, when the opposite sides of the display panel 200 along the first direction X are respectively within the shooting field of view of the camera 130 and their positions are recorded by the camera 130, the length of the display panel 200 can be calculated through the software built into the camera 130 or the exported position data. Assuming the width of the display panel 200 is along the third direction Z, when opposite sides of the display panel 200 along the third direction Z are within the field of view of the camera 130 and their positions are recorded by the camera 130, the width of the display panel 200 can be calculated using the software built into the camera 130 or the exported position data. Furthermore, the length and width of the display panel 200 can be measured together, for example, by measuring the positions of the two diagonal endpoints of the display panel 200.

[0038] This application can improve the moving efficiency of the display panel 200 while ensuring that the display panel 200 is accurately positioned within the field of view of the camera 130 through precise control of the motor assembly 110, thereby improving the moving accuracy of the display panel 200 during the size measurement process. In addition, by setting up the camera 130 and cooperating with the transfer platform 120 and the motor assembly 110, this application can capture the side position of the display panel 200 during the automatic movement of the display panel 200, and then calculate the length and / or width of the display panel 200. This avoids the problem of the operator manually adjusting the focal length of the electron microscope to achieve clear focus on the display panel 200 in the prior art, thereby improving the measurement efficiency of the size of the display panel 200.

[0039] Figure 2 This is a schematic diagram of the mobile device according to this application with the display panel in the end-of-shoot position. In some embodiments, such as... Figure 1 and Figure 2As shown, the transfer platform 120 has a starting shooting position and an ending shooting position on the slide rail. In the starting shooting position, the display panel 200 is positioned along a first direction X, with its first side within the shooting field of view of the camera 130, and / or, the display panel 200 is positioned along a third direction Z, with its second side within the shooting field of view of the camera 130. In the ending shooting position, the display panel 200 is positioned along a third direction X, with its third side within the shooting field of view of the camera 130, and / or, the display panel 200 is positioned along a fourth direction Z, with its fourth side within the shooting field of view of the camera 130. Specifically, the starting and ending shooting positions can also be set sequentially along the first direction X, or sequentially in the opposite direction of the first direction X. Without loss of generality, assuming the display panel 200 has its length along the first direction X, at the initial shooting position, the first side of the display panel 200 along the first direction X is within the field of view of the camera 130, and at the end shooting position, the third side of the display panel 200 along the first direction X is within the field of view of the camera 130. After the camera 130 records the positions of the first and third sides of the display panel 200, the length of the display panel 200 can be calculated using the software built into the camera 130 or the exported position data. Similarly, assuming the display panel 200 has its width along the third direction Z, at the initial shooting position, the second side of the display panel 200 along the third direction Z is within the field of view of the camera 130, and at the end shooting position, the fourth side of the display panel 200 along the third direction Z is within the field of view of the camera 130. After the camera 130 records the positions of the second and fourth sides of the display panel 200, the width of the display panel 200 can be calculated using the software built into the camera 130 or the exported position data. Furthermore, the length and width of the display panel 200 can be measured together. For example, by measuring the positions of the two opposite corners of the display panel 200, the length and width of the display panel 200 can be calculated simultaneously.

[0040] In some embodiments, the transfer platform 120 has a pick-up position and a drop-off position on the slide rail. The pick-up position, the start shooting position, the end shooting position, and the drop-off position can be sequentially set along the first direction X. Specifically, in some alternative embodiments, the pick-up position, the start shooting position, the end shooting position, and the drop-off position can also be sequentially set along the opposite direction of the first direction X, and this application does not limit this. The pick-up position is used to retrieve the display panel 200 from elsewhere by means of a robotic arm or the like and place it on the transfer platform 120, and to start the movement of the display panel 200. The drop-off position is used to remove the display panel 200 from the transfer platform 120 and place it in another position by means of a robotic arm or the like after the movement of the display panel 200 is completed. In this embodiment, by setting the pick-up position and the drop-off position, and combining the operation of the robotic arm on the display panel 200, the picking up and dropping of the display panel 200 can be automated, improving the movement efficiency or size measurement efficiency of the display panel 200.

[0041] In some embodiments, the line rate of the images captured by the camera 130 is matched with the speed at which the motor assembly 110 moves the display panel 200 along the slide rail. Specifically, when the camera 130 is a line scan camera, the line rate of the images captured by the camera 130 refers to the number of image lines scanned per second by the sensor. The line rate of the camera 130 must be high enough to ensure that the distance the display panel 200 moves during each line exposure time is less than one pixel of the image captured by the camera 130. Matching the line rate of the images captured by the camera 130 with the speed at which the motor assembly 110 moves the display panel 200 along the slide rail improves the image sharpness of the images captured by the camera 130 on the display panel 200.

[0042] In some embodiments, continue to refer to Figure 1 and Figure 2 The moving device 100 of the display panel 200 also includes a light source 140. The light source 140 and the camera 130 are located on the same side of the motor assembly 110. Along the second direction Y, the light source 140 is located between the camera 130 and the transfer platform 120; the light direction of the light source 140 is perpendicular to the first direction X. Specifically, in some alternative embodiments, the light direction of the light source 140 may not be perpendicular to the first direction X, as long as it is ensured that the light from the light source 140 can illuminate the corresponding side of the display panel 200 at the starting and ending shooting positions, so as to improve the imaging brightness of the display panel 200 captured by the camera 130 and improve the dimensional measurement accuracy of the display panel 200. When the camera 130 is a line scan camera 130, the camera 130 captures the side of the display panel 200, and the light source 140 can be strip-shaped to illuminate the side of the display panel 200, thereby further improving the dimensional measurement accuracy of the display panel 200.

[0043] In some embodiments, the illumination area of ​​the light source 140 at least partially overlaps with the field of view of the camera 130. By setting the illumination area of ​​the light source 140 to at least partially overlap with the field of view of the camera 130, this embodiment can increase the brightness within the field of view of the camera 130, thereby increasing the imaging brightness of the display panel 200 captured by the camera 130, and further improving the dimensional measurement accuracy of the display panel 200. Optionally, the illumination area of ​​the light source 140 completely covers the field of view of the camera 130 to maximize the brightness within the field of view of the camera 130.

[0044] In some embodiments, continue to refer to Figure 1 and Figure 2The transfer platform 120 has a starting shooting position and an ending shooting position on the slide rail. At the starting shooting position, a first side of the display panel 200 along the first direction X is located within the illumination area of ​​the light source 140, and / or, a second side of the display panel 200 along the third direction Z is located within the illumination area of ​​the light source 140. At the ending shooting position, a third side of the display panel 200 along the first direction X is located within the illumination area of ​​the light source 140, and / or, a fourth side of the display panel 200 along the third direction Z is located within the illumination area of ​​the light source 140. In this embodiment, by ensuring that the side of the display panel 200 being photographed by the camera 130 is within the illumination area of ​​the light source 140 at both the starting and / or ending shooting positions, the display panel 200 is illuminated by the light source 140 during each shot taken by the camera 130. This improves the image brightness of the display panel 200 captured by the camera 130, thereby further improving the dimensional measurement accuracy of the display panel 200.

[0045] In some embodiments, continue to refer to Figure 1 and Figure 2 The moving device 100 of the display panel 200 further includes a fixing component 150. The fixing component 150 includes a bottom end and a top end disposed along a second direction Y. A motor assembly 110 is located at the bottom end of the fixing component 150, and a camera 130 and a light source 140 are respectively fixed to the top end of the fixing component 150. Specifically, the fixing component 150 can be a gantry frame, with the motor assembly 110 and the gantry frame fixed to the same platform, or the motor assembly 110 located in the middle of the interior of the gantry frame; this disclosure does not limit this. The camera 130 and the light source 140 are respectively fixed to the top end of the fixing component 150 to facilitate photographing and illuminating the display panel 200 located below.

[0046] In some embodiments, the motor assembly 110 is communicatively connected to the camera 130. Specifically, both the motor assembly 110 and the camera 130 can have communication modules internally to achieve communication. The motor assembly 110 can send the movement speed of the display panel 200 to the camera 130 so that the camera 130 can adjust the shooting line frequency. Alternatively, the camera 130 can send the adjusted shooting line frequency to the motor assembly 110 so that the motor assembly 110 can adjust the movement speed of the display panel 200. Optionally, the motor assembly 110 and the camera 130 may not be communicatively connected, and the movement speed of the display panel 200 driven by the motor assembly 110 and the line frequency of the camera 130 can be individually set to match. Through the above settings, this embodiment can match the line frequency of the image captured by the camera 130 with the speed at which the motor assembly 110 drives the display panel 200 along the slide rail, thereby improving the imaging clarity of the image captured by the camera 130 from the display panel 200.

[0047] As can be seen from the above embodiments, this application achieves at least the following beneficial effects:

[0048] The display panel moving device provided in this application includes: a motor assembly, which includes a stator extending along a first direction, a slide rail fixedly connected to the stator, and a mover connected to the slide rail; the slide rail extends along the first direction; a transfer platform, which is fixedly connected to the mover; the transfer platform includes a platform body and multiple adsorption units disposed on the upper surface of the platform body; the display panel is adsorbed onto the multiple adsorption units. This application sets up a transfer platform to support the display panel, and uses multiple adsorption units on the upper surface of the platform body to adsorb the display panel, ensuring the display panel is fixed to the transfer platform and preventing displacement of the display panel during movement. Simultaneously, a motor assembly is provided, and the mover connected to the slide rail by the motor assembly is fixedly connected to the transfer platform, enabling the transfer platform to move along the slide rail of the motor assembly in the first direction under the combined drive of the stator and the mover. Compared to the manual movement of the display panel in the prior art, this application can significantly improve the movement efficiency of the display panel.

[0049] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this disclosure and should not be construed as limiting the specific implementation of this disclosure to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this disclosure, and all such modifications and substitutions should be considered within the scope of protection of this disclosure.
