[0054] Preferably, a regular centering mechanism 3 is further included. The regular centering mechanism 3 is divided into two groups and is respectively arranged on both sides of the vacuum adsorption stage mechanism 1 along the X-axis direction. The number of one group of the regular centering mechanism 3 is two and is respectively arranged on both sides of the vacuum adsorption stage mechanism 1 close to the Y-axis direction.

[0055] Preferably, the regular centering mechanism 3 includes a fixed block 31, a regular cylinder 32, a one-dimensional moving platform 34, and a regular block 36 from bottom to top in sequence. The regular cylinder 32 is installed on the bottom plate 13 of the vacuum adsorption stage mechanism 1 through the fixed block 31 at the bottom. The driving end of the regular cylinder 32 is drivingly connected to the one-dimensional moving platform 34 above in the X-axis direction through a connecting plate 33. The one-dimensional moving platform 34 is connected to the regular block 36 above through a moving plate 35.

[0056] Preferably, the regular block 36 is a rubber block.

[0057] Preferably, the vacuum stage unit includes a first vacuum stage 11 and a second vacuum stage 12. A plurality of first vacuum stages 11 are arranged on one side of the top of the bottom plate 13 along the negative X-axis direction, and a plurality of second vacuum stages 12 are arranged on one side of the top of the bottom plate 13 along the positive X-axis direction.

[0058] Preferably, the suction cup mechanism includes a plurality of disc-shaped suction cups 21, a plurality of short-strip ceramic suction cups 22, a plurality of square ceramic suction cups 23, and a plurality of long-strip ceramic suction cups 24. A plurality of openings are formed on the vacuum carrier unit for the disc-shaped suction cups 21, short-strip ceramic suction cups 22, square ceramic suction cups 23, and long-strip ceramic suction cups 24 to pass through freely. The disc-shaped suction cups 21, short-strip ceramic suction cups 22, and square ceramic suction cups 23 are arranged on both sides of the lifting frame 25 along the Y-axis direction along the X-axis direction, and a plurality of long-strip ceramic suction cups 24 are evenly arranged inside the lifting frame 25 along the Y-axis direction and are arranged along the X-axis direction.

[0059] Preferably, the vacuum adsorption carrier mechanism 1 further includes a sensor 14, and the sensor 14 is installed on one side of the bottom plate 13 along the X-axis direction.

[0060] Preferably, the handling mechanism 5 further includes a CCD image 54, and the CCD image 54 is installed on one side of the combined frame 51 along the X-axis direction.

[0061] Preferably, a linkage rod is connected between the driving ends around the top of the synchronous motion mechanism 4.

[0062] As Figure 1 shown, the present invention includes a vacuum adsorption carrier mechanism 1, a receiving lifting mechanism 2, a rectifying and centering mechanism 3, a synchronous motion mechanism 4, a handling mechanism 5, and other functional modules. The synchronous motion mechanism 4 is installed on the vacuum adsorption carrier mechanism 1, and the receiving lifting mechanism 2 is connected to the vacuum adsorption carrier mechanism 1 through the synchronous motion mechanism 4 to realize the transfer action of the OLED display screen. The rectifying and centering mechanism 3 is installed on the side of the vacuum adsorption carrier mechanism 1 to complete the rectifying action of the flexible display screen. The handling mechanism 5 realizes the adsorption and handling actions of the OLED display screen through a motion module (not shown in the figure).

[0063] As Figure 2 shown, the vacuum adsorption carrier mechanism 1 includes a vacuum carrier unit. The vacuum carrier unit includes a first vacuum carrier 11 and a second vacuum carrier 12. Five first vacuum carriers 11 and five second vacuum carriers 12 are symmetrically arranged and installed on the bottom plate 13. The advantage is that each first vacuum carrier 11 and second vacuum carrier 12 can be controlled separately to achieve the purpose of controlling the vacuum adsorption in different regions. The sensor 14 is installed on the bottom plate 13 to detect the position information when the receiving lifting mechanism 2 actually works.

[0064] As Figure 5 shown, the synchronous motion mechanism 4 is fixedly installed on the bottom plate 13, driven by a motor, and relies on the linkage cooperation between each other to ensure the synchronous lifting of the four support points, thereby realizing the stable lifting of the working platform, and the synchronous error of the four support points is small.

[0065] AsFigure 3 As shown, the material receiving and lifting mechanism 2 includes a suction cup mechanism. The suction cup mechanism includes several disc-shaped suction cups 21, several short-strip ceramic suction cups 22, several square ceramic suction cups 23, and several long-strip ceramic suction cups 24. The number of disc-shaped suction cups 21 is two, and they are symmetrically installed at both ends of one side of the lifting frame 25 along the negative X-axis direction. The number of short-strip ceramic suction cups 22 is 12, which are evenly divided into two groups, and the two groups of short-strip ceramic suction cups 22 are symmetrically installed inside both ends of the lifting frame 25. The number of square ceramic suction cups 23 is four, which are evenly divided into two groups, and the two groups of square ceramic suction cups 23 are symmetrically installed at the middle of the lifting frame 25 and both ends of one side along the positive X-axis direction. The number of long-strip ceramic suction cups 24 is four, and they are evenly distributed along the Y-axis direction inside the lifting frame 25. The long-strip ceramic suction cups 24 penetrate through the inside of the lifting frame 25 along the X-axis direction.

[0066] The suction cup mechanism adsorbs the flexible OLED display screen grabbed by the manipulator in a vacuum state to complete the material receiving action. The lifting frame 25 is connected to the vacuum adsorption stage mechanism 1 through the synchronous motion mechanism 4 to synchronously complete the feeding action of the material receiving and lifting mechanism 2. The vacuum adsorption stage mechanism 1 turns on the vacuum to adsorb the flexible OLED display screen, and at the same time, the suction cup mechanism blows air in the reverse direction to break the vacuum and release the material.

[0067] As Figure 4 shown, the number of the regular alignment mechanisms 3 is four and they are divided into two groups. The two groups of regular alignment mechanisms 3 are symmetrically installed on both sides of the vacuum adsorption stage mechanism 1 along the X-axis direction. Two regular alignment mechanisms 3 in one group are respectively arranged along the Y-axis direction at positions close to both sides of the vacuum adsorption stage mechanism 1.

[0068] The regular alignment mechanism 3 includes a fixed block 31, a regular alignment cylinder 32, a connecting plate 33, a one-dimensional moving platform 34, a moving plate 35, and a resin regular alignment block 36. The fixed block 31 is installed on the vacuum adsorption stage mechanism 1, and the regular alignment cylinder 32 is installed on the fixed block 31. The regular alignment action of the resin regular alignment block 36 is completed through air circuit control. The one-dimensional moving platform 34 is fixed on the regular alignment cylinder through the connecting plate 33, and the one-dimensional moving platform 34 is finely adjusted to reliably align the flexible OLED display screen. The regular alignment block 36 is installed on the one-dimensional moving platform 34 through the moving plate 35. The resin regular alignment block 36 can well protect the display screen when aligning the flexible display screen.

[0069] As Figure 6As shown in the figure, the handling mechanism 5 includes a combined frame 51, a porous ceramic stage 52, a handling cylinder 53, and a CCD camera 54. The CCD camera 54 is installed on the side of the combined frame 51 to detect the state of the flexible OLED display screen and is used to determine whether to continue with the next adsorption and handling instruction. The porous ceramic stage 52 is connected to the combined frame 51 through a plurality of handling cylinders 53 and is used for vacuum suction of materials. The vacuum adsorption stage mechanism 1 blows air in the reverse direction (breaks the vacuum) to keep the product in a suspended state, and the centering mechanism 3 centers the product.

[0070] As Figure 7 , the porous ceramic stage 52 is divided into five regions A, B, C, D, and E. Among them, the solid lines between the five regions A, B, C, D, and E in the figure represent the dividing lines.

[0071] When opening the vacuum, first open the vacuum in region C, then open the vacuum in regions B and D, and finally open the vacuum in regions A and E. The product is sucked up by the porous ceramic stage 52. The combined frame 51 is installed on the motion module to realize the vacuum suction of materials and the handling of materials by the entire handling mechanism 5.

[0072] In the product of the present invention, when the product is kept suspended, it is sucked up by the porous ceramic from the middle to both sides in sequence, so the product will not be damaged and no wrinkles will be generated.

[0073] The product of the present invention is applicable to products of various sizes and has strong versatility.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
