[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the display panel manufacturing industry, suction-type platforms are widely used for supporting and fixing displays. Existing suction-type platforms are generally complete flat platforms or composed of several small flat surfaces. The flat platform has vacuum suction holes that are connected to vacuum pipelines. The panel or other flat display screens are suctioned onto the flat platform through the vacuum suction holes, fixing their position relative to the platform, thereby achieving the purpose of fixing the display panel.

[0029] Current adsorption platforms are effective at adsorbing flat-surfaced displays. However, when foreign objects are present on the adsorption platform, the entire display screen can be easily damaged by the pressure on the metal leads.

[0030] In view of this, this application provides an adsorption stage and its preparation method to solve the problem of pressure damage that exists in the process of adsorbing a display screen using an existing stage.

[0031] Figure 1 This is a schematic diagram of the structure of an adsorption stage provided in one embodiment of this application.

[0032] Figure 2 This is a schematic diagram of the planar structure of the adsorption stage provided in one embodiment of this application.

[0033] Figure 3 This is a schematic diagram of the planar structure of the support mechanism in an adsorption platform provided in one embodiment of this application. (In conjunction with...) Figures 1 to 3As shown, the adsorption platform 1 of this embodiment is used to support the display screen 2, which includes a display area 21 and a binding area 22 located on one side of the display area 21. The uneven area of ​​the display screen 2 corresponds to the binding area 22. The platform 1 includes an adsorption mechanism 10 and a support mechanism 11. The adsorption mechanism 10 includes a plurality of adsorption parts 12 for adsorbing the display area 21. The adsorption mechanism 10 and the support mechanism 11 may have a certain height difference, and the adsorption mechanism 10 and the support mechanism 11 are fixedly connected. The support mechanism 11 includes a hollow area 111, in which a fixing unit 113 and a movable unit 112 located on at least one side of the fixing unit 113 are provided. Both the movable unit 112 and the fixing unit 113 are provided with adsorption parts 12 for adsorbing the binding area 22, and the movable unit 112 is movable relative to the fixing unit 113.

[0034] The movable unit 112 can be located on the left or right side of the fixed unit 113, or on both sides of the fixed unit 113. The fixed unit 113 serves as a support to prevent deformation and cracking during the adsorption and binding of the area 22.

[0035] For example, the shape of the fixing unit 113 includes rectangle, square, etc., which can meet the usage requirements of various environments. Regardless of the shape of the fixing unit 113, better stability can be achieved, and you can choose according to your actual usage.

[0036] For example, multiple adsorption units 12 can be evenly arranged on the fixed unit 113 and the movable unit 112.

[0037] For example, the display screen 2 may be a flexible display screen, including but not limited to flexible display screens.

[0038] Specifically, the adsorption mechanism 10 is the main platform. The adsorption mechanism 10 is the main body of the stage 1, and its surface is the contact surface with the display screen 2, capable of supporting the display area 21 of the display screen 2. The adsorption mechanism 10 has multiple adsorption sections 12. These multiple adsorption sections 12 can be arranged in an array or irregularly.

[0039] The support mechanism 11 is a sub-platform, and it is divided into a hollowed-out area 111 and a non-hollowed-out area 110. The non-hollowed-out area 110 is located around the hollowed-out area 111. The hollowed-out area 111 of the support mechanism 11 corresponds to the binding area 22 of the display screen 2. The position, size, and shape of the hollowed-out area 111 are adapted to the binding area 22 of the display screen 2, and the hollowed-out area 111 can at least cover the binding area 22, so that the hollowed-out area 111 is aligned with the binding area 22 of the display screen 2.

[0040] Preferably, both the hollow area 111 and the binding area 22 are rectangular in shape.

[0041] For example, the number of adsorption units 12 can be set according to needs, and there can be multiple units. The shape and vacuum degree of the adsorption units 12 can be set according to adsorption requirements. The adsorption units 12 need to be adapted to the display screen 2 to be adsorbed.

[0042] It should be understood that the display screen has a reserved bonding area 22 at the edge of the screen body. The metal leads in the bonding area are connected to the FPC (flexible printed circuit) through anisotropic conductive film (ACF). The screen body is electrically connected to the external power supply through the FPC, thereby realizing the lighting.

[0043] In practical application, the display screen 2 is first placed on the adsorption platform 1. The multiple adsorption parts 12 of the adsorption mechanism 10 adsorb the display area 21 of the display screen 2. A protective film 3 can be placed between the adsorption mechanism 10 and the display area 21 to protect the display area 21 and prevent it from being damaged. Then, the movable unit 112 moves away from the fixed unit 113 within the hollow area 111. When the movable unit 112 moves to the dummy area 23 (wireless area) of the binding area 22, the adsorption parts 12 of the movable unit 112 and the fixed unit 113 adsorb the binding area 22 of the display screen 2, completing the adsorption of the display screen 2. Finally, the support film 4 can be attached to the non-display side of the display screen 2 to provide support and protection for the display screen.

[0044] The adsorption platform provided in this application embodiment has a hollowed-out area 111 in the support mechanism 11. The hollowed-out area 111 is provided with a movable unit 112 and a fixed unit 113. After the movable unit 112 moves to the dummy area 23 of the display screen, the binding area 22 is adsorbed by multiple adsorption parts 12. Compared with the traditional platform 1 adsorbing the entire binding area 22, it effectively reduces the occurrence rate of defects such as pressure damage and scratches on the binding area 22, improves product yield, and increases product cost advantage.

[0045] Continue as Figure 3 As shown, in some embodiments, the support mechanism 11 is provided with a sliding rail 13, the movable unit 112 is slidably connected to the sliding rail 13, the fixed unit 113 is fixedly connected to the sliding rail 13, and the movable unit 112 moves away from or close to the fixed unit 113 along the extension direction of the sliding rail 13.

[0046] For example, the sliding rail 13 can be fixedly installed in the non-hollowed-out area 110. The sliding rail 13 can be configured to receive the movable unit 112, and the movable unit 112 can move relative to the fixed unit 113.

[0047] For example, the cross-sectional shape of the sliding track 13 can be elliptical, quadrilateral, or other irregular shape, and the extending direction of the sliding track 13 is... Figure 3 The X direction in the equation.

[0048] For example, the bearing surfaces of the movable unit 112 and the fixed unit 113 are coplanar with the bearing surface of the bearing mechanism 11. The shapes of the movable unit 112 and the fixed unit 113 include rectangles and squares.

[0049] The adsorption platform provided in this application embodiment has a sliding track 13 on the support mechanism 11. The movable unit 112 is slidably connected to the sliding track 13. The fixed unit 113 can play a supporting role when the movable unit 112 moves along the extension direction of the sliding track 13, so as to keep the support mechanism 11 stable, improve the reliability and stability of the adsorption platform 1, and facilitate the adsorption of the display screen 2.

[0050] Figure 4 This is a schematic diagram of the planar structure of the support mechanism in an adsorption stage provided in another embodiment of this application. (See diagram below.) Figure 4 As shown, a fixed unit 113, a first movable unit 101, and a second movable unit 102 are provided in the hollow area 111. Multiple adsorption parts 12 are provided on both the first movable unit 101 and the second movable unit 102. The bearing surface of the fixed unit 114 and the bearing surface of the bearing mechanism 11 are coplanar.

[0051] For example, the first movable unit 101 and the second movable unit 102 are located on both sides of the fixed unit 114. The fixed unit 114 can be set at the center of the hollow area 111, and the movement range of the first movable unit 101 along the extension direction of the sliding track 13 is equal to the movement range of the second movable unit 102.

[0052] For example, the bearing surfaces of the first movable unit 101 and the second movable unit 102 are coplanar with the bearing surface of the fixed unit 114.

[0053] Specifically, when the first movable unit 101 and the second movable unit 102 move away from each other along the extension direction of the sliding track 13, the fixing unit 114 provides support for the first movable unit 101 and the second movable unit 102.

[0054] The adsorption platform provided in this embodiment of the application is further provided with a first movable unit 101 and a second movable unit 102 in the hollow area 111. When the first movable unit 101 and the second movable unit 102 move to the Dummy area 23 (wireless area) respectively, the adsorption part 12 of the first movable unit 101 and the second movable unit 102 adsorbs the binding area 22 of the display screen 2, thus completing the adsorption work of the display screen 2. The fixing unit 114 can not only adsorb the binding area 22, but also play a very stable support function, further improving the adsorption effect and accuracy of the display screen 2.

[0055] Figure 5 This is a schematic diagram of the structure of an adsorption stage provided in another embodiment of this application. Figure 5 As shown, the platform 1 also includes a first drive unit 115 and a second drive unit 116. The first movable unit 101 is electrically connected to the first drive unit 115, and the first drive unit 115 controls the displacement of the first movable unit 101. The second movable unit 102 is electrically connected to the second drive unit 116, and the second drive unit 116 controls the displacement of the second movable unit 102.

[0056] For example, the first drive unit 115 can be powered by the first movable unit 101 with the output axis. The second drive unit 116 can be powered by the second movable unit 102 with the output axis. The first drive unit 115 and the second drive unit 116 can be actuators such as lead screw mechanisms and cylinders, or they can be drive motors.

[0057] Specifically, in combination Figure 4 and Figure 5 As shown, the first movable unit 101 can be driven to move to the left on the sliding track 13 by the first driving unit 115, and the displacement of the first movable unit 101 can be controlled. When the first movable unit 101 moves to the dummy area 23 on the left side of the display screen 2, the first driving unit 115 stops working, and the adsorption part 12 of the first movable unit 101 begins to adsorb the left side of the binding area 22. Similarly, the second movable unit 102 can be driven to move to the right on the sliding track 13 by the second driving unit 116, and the displacement of the second movable unit 102 can be controlled. When the second movable unit 102 moves to the dummy area 23 on the right side, the second driving unit 116 stops working, and the adsorption part 12 of the second movable unit 102 begins to adsorb the right side of the binding area 22.

[0058] The adsorption platform provided in this application embodiment further includes a first driving unit 115 and a second driving unit 116. A first movable unit 101 is electrically connected to the first driving unit 115, and a second movable unit 102 is electrically connected to the second driving unit 116. The first driving unit 115 controls the displacement of the first movable unit 101, and the second driving unit 116 controls the displacement of the second movable unit 102. This ensures the accuracy of the movement range of the first movable unit 101 and the second movable unit 102, and ensures that the adsorption operation is performed in the dummy area 23 of the display screen 2. This helps to prevent foreign objects from damaging the bonding area 22 and improves the poor damage to the metal lines in the bonding area 22.

[0059] Figure 6 This is a schematic diagram of the planar structure of the support mechanism in an adsorption stage provided in another embodiment of this application. For example... Figure 6 As shown, both the first movable unit 101 and the second movable unit 102 are equipped with a detection device 14, which is used to detect the attachment status of the display screen 2.

[0060] For example, the detection devices 14 on the first movable unit 101 and the second movable unit 102 can be symmetrically arranged, and the detection devices 14 can be positioned facing the display screen 2. The detection devices 14 can be sensors in the form of optical fibers, photoelectric sensors, etc.

[0061] In some other embodiments, the detection device 14 can detect whether the first movable unit 101 and the second movable unit 102 have moved to... Figure 5 Dummy region 23 in the middle.

[0062] The adsorption platform provided in this application embodiment is equipped with a detection device 14 on both the first movable unit 101 and the second movable unit 102. The detection device 14 is used to detect the attachment status of the display screen 2 and realize the effective adsorption of the display screen 2.

[0063] Figure 7 This is a schematic diagram of the planar structure of the support mechanism in an adsorption stage provided in another embodiment of this application. For example... Figure 7 As shown, the platform 1 also includes a control unit 15, the detection device 14 is electrically connected to the control unit 15, the first drive unit 115 and the second drive unit 116 are both electrically connected to the control unit 15, and the control unit 15 controls the first drive unit 115 and the second drive unit 116 to turn on or off.

[0064] For example, when the first drive unit 115 and the second drive unit 116 are motors, the control unit 15 can process the motor control signals to realize various control modes such as motor start / stop, forward / reverse rotation, speed, and torque. The control unit 15 is composed of a microprocessor and can implement various control algorithms, including timing control, PID control, and vector control, to flexibly adapt to the control needs of various motors.

[0065] Specifically, in combination Figure 5 and Figure 7 As shown, when the detection device 14 detects that the first movable unit 101 and the second movable unit 102 have respectively moved to... Figure 5 When the dummy region 23 is in the middle, the control unit 15 receives the position signal sent by the detection device 14 and controls the first drive unit 115 and the second drive unit 116 to turn off, the first movable unit 101 and the second movable unit 102 stop moving, and the multiple adsorption parts 12 included in the first movable unit 101 and the second movable unit 102 adsorb the binding region 22.

[0066] The adsorption platform provided in this application embodiment also includes a control unit 15. The detection device 14, the first drive unit 115 and the second drive unit 116 are all electrically connected to the control unit 15. The control unit 15 controls the first drive unit 115 and the second drive unit 116 to open or close. Various control, calculation and data processing functions are realized through the control unit 15, which is conducive to meeting various automation control needs and makes the adsorption platform 1 more widely applicable.

[0067] In some embodiments, the stage 1 further includes an adsorption generating device configured to generate an adsorption force in the adsorption section 12; preferably, the adsorption force is at least one of vacuum adsorption, electrostatic adsorption or magnetic adsorption.

[0068] In some embodiments, the movable unit 112 is provided with an air knife structure 16, which is at least located on one side facing the moving direction of the movable unit 112, and the air outlet direction of the air knife structure 16 is facing the bearing surface of the movable unit 112.

[0069] Figure 8 This is a schematic diagram of the planar structure of the support mechanism in an adsorption stage provided in another embodiment of this application. For example... Figure 8 As shown, both the first movable unit 101 and the second movable unit 102 are provided with air knife structures 16, and the air outlet direction of the air knife structure 16 is set towards the binding area 22.

[0070] Among them, the air knife structure 16 can fully dry the surface of the display screen 2.

[0071] For example, the air knife structure 16 may include multiple air knives, each of which blows air onto the bonding area 22 of the display screen 2.

[0072] The adsorption platform provided in this application embodiment is equipped with an air knife structure 16 on both the first movable unit 101 and the second movable unit 102. The air outlet direction of the air knife structure 16 is set towards the binding area 22. The air knife structure 16 is used to thoroughly dry the surface of the display screen 2, which can improve the drying speed of the surface of the display screen 2, ensure the cleanliness of the surface of the display screen 2, and prevent foreign objects from damaging the binding area 22 during the adsorption process.

[0073] In other embodiments of this application, the fixed unit 113 and / or the movable unit 112 are also provided with foreign object detection sensors (not shown in the figure). When the foreign object detection sensor detects the presence of a foreign object on the display screen 2, the control unit 15 controls the air knife structure 16 to blow air.

[0074] Figure 9 This is a schematic flowchart illustrating an adsorption method using an adsorption platform according to an embodiment of this application. Figure 9 As shown, the method includes the following steps.

[0075] Step 900: Provide an adsorption platform and a display screen, and place the display screen on the adsorption platform.

[0076] The display screen includes a display area and a binding area located on one side of the display area. The platform includes an adsorption mechanism and a support mechanism. The adsorption mechanism includes multiple adsorption parts for adsorbing the display area. The adsorption mechanism and the support mechanism are fixedly connected. The support mechanism includes a hollow area. A fixed unit and a movable unit located on at least one side of the fixed unit are provided in the hollow area. Both the fixed unit and the movable unit are provided with adsorption parts. The movable unit is movable relative to the fixed unit.

[0077] For example, an adsorption stage is used for supporting and fixing a display screen. Multiple adsorption parts on the adsorption mechanism can adsorb the display area.

[0078] Step 901: Control the movable unit to move in a direction away from the fixed unit.

[0079] Step 902: When the movable unit moves to the preset limit position, the uneven area of ​​the display screen is adsorbed by the multiple adsorption parts included in the movable unit and the fixed unit respectively.

[0080] Among them, the preset limit position corresponds to the wireless area of ​​the display screen.

[0081] Specifically, when the adsorption stage uses vacuum adsorption, it is ensured that each adsorption part and the display screen are kept within a range that allows for smooth vacuum adsorption. Then, the vacuum pressure is turned on so that each area of ​​the display screen is adsorbed onto its respective adsorption part.

[0082] Of course, the adsorption stage can also use electrostatic adsorption or magnetic adsorption.

[0083] The adsorption method of the adsorption stage provided in this application embodiment controls the movable unit to move away from the fixed unit. When the movable unit moves to a preset limit position, the multiple adsorption parts included in the movable unit and the fixed unit are used to adsorb the uneven area of ​​the display screen. Compared with the traditional technology of adsorbing the uneven area of ​​the entire stage, it can effectively reduce the occurrence rate of defects such as pressure marks and scratches on the uneven area, improve product yield, and increase product cost advantage.

[0084] In some embodiments, the movable unit includes a first movable unit and a second movable unit, both of which are provided with adsorption portions. The first movable unit and the second movable unit are respectively located on both sides of the fixed unit. The adsorption method further includes: controlling the first movable unit and the second movable unit to move away from the fixed unit; when the first movable unit and the second movable unit move to preset limit positions respectively, using the multiple adsorption portions included in the first movable unit, the second movable unit and the fixed unit to adsorb the uneven area of ​​the display screen.

[0085] Figure 10 This is a schematic flowchart illustrating an adsorption method for an adsorption platform according to another embodiment of this application. Figure 10 As shown, the platform also includes a first drive unit, a second drive unit, and a control unit. The first movable unit is electrically connected to the first drive unit, and the second movable unit is electrically connected to the second drive unit. Both the first movable unit and the second movable unit are equipped with detection devices. The detection devices, the first drive unit, and the second drive unit are all electrically connected to the control unit. Controlling the first movable unit and the second movable unit to move away from the fixed unit includes the following steps.

[0086] Step 9021: The control unit controls the first drive unit and the second drive unit to turn on, the first drive unit drives the first movable unit and the second drive unit drives the second movable unit to move away from each other.

[0087] When the first movable unit and the second movable unit move to the preset limit position respectively, the uneven area of ​​the display screen is adsorbed by the multiple adsorption parts included in the first movable unit, the second movable unit and the fixed unit, including the following steps.

[0088] Step 9031: When the detection device detects that the first movable unit and the second movable unit have moved to the preset limit position respectively, the control unit controls the first driving unit and the second driving unit to shut down, and the first movable unit and the second movable unit stop moving. The uneven area of ​​the display screen is adsorbed by the multiple adsorption parts included in the first movable unit, the second movable unit and the fixed unit respectively.

[0089] The adsorption method of the adsorption stage provided in this application embodiment is equipped with a detection device on both the first movable unit and the second movable unit. The detection device facilitates the detection of the attachment status of the display screen, thereby achieving effective adsorption of the display screen. The control unit can control the first driving unit and the second driving unit to open or close. Various control, calculation, and data processing functions are realized through the control unit, which is conducive to meeting various automation control requirements and making the adsorption stage more widely applicable.

[0090] Figure 11 This is a schematic flowchart illustrating an adsorption method for an adsorption platform according to another embodiment of this application. Figure 11 As shown, the movable unit is equipped with an air knife structure, and the method also includes the following steps.

[0091] Step 903: When the movable units move away from each other, the air knife structure blows air towards the uneven area of ​​the display screen to blow away foreign objects in the uneven area.

[0092] The adsorption method of the adsorption stage provided in this application embodiment allows the air knife structure to blow air onto the uneven area of ​​the display screen when the movable unit moves away from the fixed unit, so as to blow away foreign objects in the uneven area.
