[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a display device manufacturing apparatus, as shown in Figures 1 to 6, including a conveyor frame 1, a conveyor belt structure 2 inside the conveyor frame 1, and a flipping component 3 on the surface of the conveyor frame 1;

[0032] The flipping assembly 3 includes a driven shaft 301 rotatably connected to the middle of the conveyor frame 1. A clamping frame 302 is fixedly mounted on the outer surface of the driven shaft 301. A bidirectional lead screw 303 is rotatably connected to the inner side wall of the clamping frame 302 via a support member. Sliding members are threaded to both sides of the outer surface of the bidirectional lead screw 303. A rotary motor is fixedly mounted on the side surface of the clamping frame 302. The output end of the rotary motor is fixedly mounted with the bidirectional lead screw 303. A clamping plate 304 is fixedly connected to one side of the sliding member. An anti-slip layer is provided on the side surface of the clamping plate 304. A driven gear 305 is fixedly mounted on one end of the driven shaft 301. The lower surface of the moving gear 305 is meshed with a drive gear plate 306, which is slidably connected to the side surface of the conveyor frame 1. The side surface of the drive gear plate 306 is rotatably connected to a push rod 307 via a hinge. The other end of the push rod 307 is rotatably connected to a rotating plate 308. The side surface of the conveyor frame 1 is fixedly mounted with a first motor 309 via a support frame. The output end of the first motor 309 is fixedly mounted with a drive shaft. One end of the drive shaft is fixedly mounted with a rotating plate 308. The outer surface of the rotating plate 308 is rotatably connected to a support ring. The side surface of the support ring is fixedly mounted with the side surface of the conveyor frame 1 via a clamping plate.

[0033] Working principle: The operator places the display device on the surface of the conveyor belt structure 2. After the display device moves into the clamping frame 302, the rotary motor is started to drive the bidirectional lead screw 303 to rotate. The rotation of the bidirectional lead screw 303 causes the sliding parts on both sides to slide towards the center. The sliding parts drive the clamping plate 304 at one end to move, and the clamping plates 304 on both sides clamp and fix the display device. Then, the first motor 309 is started to drive the rotating plate 308 to rotate. The rotating plate 308 drives the push rod 307 on one side to move. The movement of the push rod 307 causes the drive toothed plate 306 at one end to slide back and forth. The movement of the drive toothed plate 306 makes the device mesh and connect. The driven gear 305 rotates, which drives the internal driven shaft 301 to rotate. The driven shaft 301 drives the clamping frame 302 on the outer surface to rotate. The clamping frame 302 drives the internal display device to rotate synchronously, thereby completing the flipping operation. Then the clamping plate 304 is released, and the display device falls onto the surface of the conveyor belt structure 2 for movement. Then the clamping frame 302 will perform a reset operation to perform the next continuous flipping operation. There is no need for manual assistance to push the display device to the surface of the conveyor belt structure, which greatly improves the automation level of the device, greatly reduces the workload of the staff, and improves the work efficiency of the staff.

[0034] Telescopic columns 4 are provided at the four corners of the inner side wall of the clamping frame 302. A buffer spring 5 is provided inside the telescopic column 4. A flexible buffer plate 6 is fixedly installed at one end of the telescopic column 4. A connecting groove is opened on both sides of the flexible buffer plate 6, and a sliding component is slidably connected inside the connecting groove.

[0035] When the display device moves into the inside of the clamping frame 302, the flexible buffer plate 6 comes into contact with the display device. The buffer spring 5 inside the telescopic column buffers the impact force generated during the contact, thereby reducing the impact force generated by the collision on the display device and improving the integrity of the display device.

[0036] Lifting frames 7 are provided on both sides above the conveyor frame 1. A first sliding groove is provided on the side surface of the lifting frame 7. A sliding block 8 is slidably connected to the side surface of the first sliding groove. A cleaning roller 9 is provided on the side surface of the sliding block 8 through a support column. A close-fitting spring 10 is provided on the side surface of the sliding block 8. The close-fitting spring 10 is fixedly installed on the inner side wall of the first sliding groove. A second sliding groove is provided on the surface of the lifting frame 7. A fixing block is fixedly installed on the upper surface of the sliding block 8. A pushing block 11 overlaps on the side surface of the fixing block. A guide column is slidably connected to the surface of the pushing block 11 and the fixing block. A spreading rod 12 is rotatably connected to the side surface of the pushing block 11 through a hinge seat. A connecting plate is rotatably connected to one end of the spreading rod 12 through the hinge seat. A fixing frame is fixedly installed on the upper surface of the lifting frame 7. An electric push rod 13 is fixedly installed on the inner top wall of the fixing frame. A connecting plate is fixedly installed at one end of the electric push rod 13.

[0037] During transport, the surface of the display device will be contaminated with dust or debris. When cleaning is required, the initial distance between the two cleaning rollers 9 is large. Then, when the display device is in a vertical position, the electric push rod 13 is activated to drive the connecting plate to slide upward. The connecting plate drives the lower support rod 12 to move. The support rod 12 drives the push block 11 to slide stably under the sliding of the guide column. At this time, the fixed block has no supporting force. Under the action of the close-fitting spring 10, it drives the sliding block 8 to reset and slide. The sliding block 8 drives the two cleaning rollers 9 to slide towards the middle, so that the cleaning rollers 9 are close to the two sides of the display device, ensuring the effectiveness and stability of cleaning.

[0038] The side surfaces of the two fixed frames are respectively fixedly installed with locking blocks. The internal thread of one locking block is connected to the lifting screw 14, and the internal sliding connection of the other locking block is a guide column. The lifting screw 14 is rotatably connected to the surface of the conveyor frame 1. The guide column is fixedly installed on the upper surface of the conveyor frame 1. The side surface of the conveyor frame 1 is fixedly installed with a second motor. The output end of the second motor is fixedly installed with a rotating shaft. The rotating shaft and the outer surface of the lifting screw 14 are provided with a pulley structure.

[0039] After the cleaning roller 9 is in close contact with both sides of the display device, the second motor is started to drive the rotating shaft to rotate. The rotating shaft drives the lifting screw 14 on the other side to rotate through the pulley structure. The rotation of the lifting screw 14 drives the fixed frame on one side of the clamp to move. The fixed frame drives the lifting frame 7 below to move synchronously. The lifting frame 7 on the other side slides stably under the guidance of the guide column, which facilitates the cleaning of the surface of the display device, facilitates subsequent processing operations, and improves the subsequent processing quality.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
