[0002] The turnover mechanism for display screen processing is an important device in the manufacturing and processing process of display screens. It is mainly used to realize the turnover, positioning and adjustment of display screens between different processes to ensure the smooth progress of the processing process and the consistency of product quality.

[0003] The existing turnover mechanism, such as a vacuum chuck mechanical device (application number: 202022401188.4) disclosed in the Chinese patent database, includes a base. A hydraulic rotating device is arranged on the upper part of the base. The hydraulic rotating device is fixedly connected with the main arm. The main arm is connected with the first sub-arm. The first sub-arm is connected with the second sub-arm. The second sub-arm is connected with the vacuum chuck mechanism. A first oil cylinder is arranged between the main arm and the first sub-arm. The main arm and the first sub-arm are connected through a first rotating shaft. The first sub-arm and the second sub-arm are connected through a second rotating shaft. A second oil cylinder is arranged between the first sub-arm and the second sub-arm. The second sub-arm and the vacuum chuck mechanism are connected through a third rotating shaft. A third oil cylinder is arranged between the second sub-arm and the vacuum chuck mechanism. The third oil cylinder is connected with the vacuum chuck mechanism through a connecting rod.

[0004] In the above vacuum chuck mechanical device, the vacuum chuck mechanism is positioned by a circle of vertically arranged bolts. During actual assembly, it is necessary to lift the vacuum chuck mechanism for assembly, and the whole process is laborious and inconvenient. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems existing in the prior art, and propose a turnover mechanism for display screen processing that is convenient for carrier installation.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A turnover mechanism for display screen processing includes a carrier, a base, a driving member arranged on the base, and a rotating shaft horizontally rotatably arranged on the base. The carrier includes a connecting frame substantially in a U shape. There are two connecting frames distributed along the axial direction of the rotating shaft. A bracket is fixed between the lower ends of the two connecting frames, and a plurality of vacuum chucks are installed on the bracket. The rotating shaft is composed of a rod body and two shaft bodies respectively formed on both end faces of the rod body. Both shaft bodies are rotatably arranged on the base. The outer surface of the rod body is polygonal. A polygonal hole matching the rod body is axially penetrated through the upper end of the connecting frame, and the connecting frame is sleeved on the rotating shaft through the corresponding polygonal hole. At least one side of the polygonal hole is open, and a bolt for tightly holding the corresponding polygonal hole to the rotating shaft is detachably fixed at the opening. The above driving member is used to drive the two connecting frames to swing around the rotating shaft simultaneously.

[0007] When in use, the flipping mechanism uses a vacuum suction cup to suck the horizontally arranged display screen, and then the driving member drives the connecting frame to swing so that the display screen is flipped to a specified angle.

[0008] The upper end of the connecting frame is fixedly connected by clamping the rotating shaft through the polygonal hole thereon, and the tightness of the polygonal hole clamping the rotating shaft is controlled by rotating the bolt. In this way, after installing the rotating shaft, the connecting frame can be inserted from one side and the bolts can be tightened to complete the connection between the two. The whole process is relatively easy and labor-saving.

[0009] At the same time, the connecting frame uses the polygonal hole to cooperate with the rod body of the rotating shaft, so that the connection load-bearing position of the connecting frame and the rotating shaft is transferred from the bolt to the polygonal hole, which can effectively reduce the force on the bolt when the flip mechanism is running, ensuring the operation of the flip mechanism and the structural stability.

[0010] In the above-mentioned flip mechanism for display screen processing, the above-mentioned connecting frame includes a main body in the shape of a U and a connecting block arranged on the upper end surface of the main body, the above-mentioned bracket is fixed between the two main bodies, the above-mentioned polygonal hole is formed between the middle of the connecting block and the corresponding main body, the above-mentioned openings are formed between the two ends of the connecting block and the corresponding main body, and the two ends of the connecting block are detachably connected to the corresponding main body through the above-mentioned bolts. The above-mentioned design is adopted to facilitate the connection between the connecting frame and the rotating shaft.

[0011] In the above-mentioned flip mechanism for display screen processing, the polygonal hole is composed of two half holes respectively arranged on the upper end surface of the main body and the middle part of the corresponding connecting block to facilitate the connection between the main body and the rotating shaft.

[0012] In the above-mentioned flip mechanism for display screen processing, a limiting structure is further provided between the main body and the rod body to further limit the axial sliding of the connecting frame, thereby further enhancing the positioning strength and stability of the connecting frame and ensuring stable operation of the flip mechanism.

[0013] In the above-mentioned display screen processing flip mechanism, the limiting structure includes a convex column formed on the bottom wall of the main half hole, and the axes of the convex column and the rotating shaft are vertically arranged, and two plug holes matching the convex column are opened on the side wall of the rod body, and the two convex columns are respectively inserted into the two plug holes. The convex column and the plug hole cooperate to effectively limit the connecting frame in the axial direction, which has the advantages of simple structure and convenient installation.

[0014] As another solution, in the above-mentioned flip mechanism for display processing, the limiting structure includes two limiting sleeves and two positioning sleeves sleeved on the rod body, the two limiting sleeves are between the two main bodies, the two main bodies are between the two positioning sleeves, the positioning sleeve is fixedly connected to the rod body, a threaded hole radially penetrates the limiting sleeve, a screw is screwed in the threaded hole, and the screw rod is tightly pressed on the side wall of the rod body; the main body is clamped in the corresponding positioning sleeve and the corresponding limiting sleeve. The main body is clamped and positioned between the corresponding positioning sleeve and the corresponding limiting sleeve, which can also stabilize the limiting main body in the axial direction.

[0015] In the above display screen processing flip mechanism, the driving member includes two hydraulic cylinders, and the piston rods of the two hydraulic cylinders are respectively fixed to the upper ends of the two connecting frames, which has the advantages of simple structure and stable operation. Naturally, it is also possible that the driving member is only one hydraulic cylinder.

[0016] In the above-mentioned display screen processing flip mechanism, a horizontal beam is arranged between the middle parts of the two connecting frames, the axes of the beam and the rotating shaft are arranged in parallel, and the two ends of the beam are respectively connected to the two connecting frames. The beam is arranged to connect the two connecting frames more stably, ensure the consistency of the movements of the two connecting frames, and further ensure the stable operation of the flip mechanism.

[0017] Compared with the prior art, the flip mechanism for display screen processing has the following advantages:

[0018] 1. The upper end of the connecting frame is fixedly connected by holding the rotating shaft through the polygonal hole thereon, and the tightness of the polygonal hole holding the rotating shaft is controlled by rotating the bolt. In this way, after installing the rotating shaft, the connecting frame is inserted from one side and the bolts are tightened to complete the connection between the two. The whole process is relatively easy and labor-saving.

[0019] 2. The connecting frame cooperates with the rod body of the rotating shaft by using the polygonal hole, so that the connection load-bearing position of the connecting frame and the rotating shaft is transferred from the bolt to the polygonal hole, which can effectively reduce the force on the bolt when the flip mechanism is running, ensuring the operation of the flip mechanism and the structural stability.

[0020] 3. The boss and the socket cooperate to effectively limit the connecting frame in the axial direction, and it has the advantages of simple structure and easy installation. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, the two shaft bodies 3b are both rotatably arranged on the base 1; the outer surface of the rod body 3a is polygonal.

[0031] When in use, the flipping mechanism uses the vacuum suction cup 6 to suck the horizontally arranged display screen, and then the driving member 2 drives the connecting frame 4 to swing so that the display screen is flipped to a specified angle.

[0032] The upper end of the connecting frame 4 is fixedly connected by holding the rotating shaft 3 through the polygonal hole 4a thereon, and the tightness of the polygonal hole 4a holding the rotating shaft 3 is controlled by rotating the bolt 7. In this way, after installing the rotating shaft 3, the connecting frame 4 is inserted from one side and the bolt 7 is tightened to complete the connection between the two. The whole process is relatively easy and labor-saving.

[0040] The driving member 2 includes two hydraulic cylinders, and the piston rods of the two hydraulic cylinders are respectively fixed to the upper ends of the two connecting frames 4, which has the advantages of simple structure and stable operation. Naturally, the driving member 2 can also be only one hydraulic cylinder. Further explanation, a crossbeam 9 is horizontally arranged between the middle parts of the two connecting frames 4, and the axes of the crossbeam 9 and the rotating shaft 3 are arranged in parallel, and the two ends of the crossbeam 9 are respectively fixed to the two connecting frames 4.
