[0024] Reference Figure 1-4 A display screen frame alignment device for display screen assembly includes a horizontally positioned intermediate plate 1 serving as a workbench. A notch is provided in the center of the intermediate plate 1, within which a conveyor belt 2 is positioned. The conveyor belt 2 is used to transport the display screen frames, and can accommodate a variety of display screen frame specifications. A lifting mechanism is provided at the bottom of the intermediate plate 1 for controlling the raising and lowering of the conveyor belt 2. A right-angled bend block 3 is fixed to the upper side of the intermediate plate 1, and a movable plate 4 is provided on the intermediate plate 1 to correspond to the right-angled bend block 3.

[0025] The movable plate 4 is matched with a driving mechanism, the upper side of the movable plate 4 is matched with a positioning mechanism for pushing the display screen frame, and the front side of the middle plate 1 is provided with a suction cup mechanism.

[0026] As a technical optimization solution of the present invention, the middle plate 1 is rectangular, and a support frame is installed at the bottom of the middle plate 1. The support frame plays a role in stably supporting the middle plate 1, and the support frame will not affect the conveyor belt 2.

[0027] As a technical optimization solution of the present invention, the lifting mechanism includes an electric lifting rod 5 vertically arranged at the bottom of the middle plate 1. The electric lifting rod 5 is fixedly connected to the support frame. The telescopic end of the electric lifting rod 5 is fixed to the bottom plate 6, and the conveyor belt 2 is mounted on the bottom plate 6. When the electric lifting rod 5 is activated, it can accurately drive the conveyor belt 2 to move up and down.

[0028] For the above example, those skilled in the art should know that when implementing the above technical solution, a power motor for driving the rotation is installed inside the conveyor belt 2 .

[0029] As a technical optimization solution of the present invention, a material conveyor belt 7 aligned with the conveyor belt 2 is provided on the right side of the middle plate 1. The height of the material conveyor belt 7 is flush with the height of the upper side of the middle plate 1. The material conveyor belt 7 is used to convey the assembled display screen rubber frame. By aligning with the conveyor belt 2, the display screen rubber frame can be transported to the conveyor belt 2.

[0030] For the above examples, those skilled in the art should know that when implementing the above technical solution, the display screen plastic frame can be placed on the material conveyor belt 7 manually, or it can be clamped and placed by a robotic arm. There is no existing placement method, and the placement orientation of the display screen plastic frame is always the same.

[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, the length of the material conveyor belt 7 can be set according to demand.

[0032] As a technical optimization solution of the present invention, the drive mechanism includes a first telescopic cylinder 8 fixed horizontally to the side of the middle plate 1. The telescopic end of the first telescopic cylinder 8 faces the front of the middle plate 1 and is aligned with the right-angle bending block 3. The movable plate 4 is fixedly connected to the telescopic end of the first telescopic cylinder 8. The first telescopic cylinder 8 is used to drive the movable plate 4 to move. The movable plate 4 pushes the display screen frame, forcing one side of the display screen frame to abut against the right-angle bending block 3, thereby achieving the positioning of the display screen frame.

[0033] As a technical optimization solution of the present invention, the positioning mechanism includes a rotating rod 9 rotatably arranged at one end of the movable plate 4. The rotating rod 9 corresponds to the right side of the middle plate 1. A rotating motor 12 is fixed to the movable plate 4 to control the rotation of the rotating rod 9. The rotating motor 12 can accurately control the rotation of the rotating rod 9. A second telescopic cylinder 10 is horizontally fixed to the rotating rod 9. The telescopic end of the second telescopic cylinder 10 faces the left side of the lower middle plate 1 and is fixed with a positioning plate 11. The second telescopic cylinder 10 can accurately push the positioning plate 11. The positioning plate 11 can push the display screen frame so that one side of the display screen frame abuts against the right-angle bending block 3, thereby achieving the positioning of the display screen frame. The bottom of the positioning plate 11 and the movable plate 4 both slide and fit with the upper side of the middle plate 1.

[0034] For the above example, those skilled in the art should know that when implementing the above technical solution, the telescopic degrees of the first telescopic cylinder 8 and the second telescopic cylinder 10 are adjustable.

[0035] As a technical optimization solution of the present invention, the suction cup mechanism includes a vertical pole 13 that is slidably arranged on the front side of the middle plate 1. A driving motor is vertically fixed to the top of the vertical pole 13. An adjustable telescopic arm 14 is coaxially fixed to the driving motor. The driving motor is used to accurately control the rotation of the adjustable telescopic arm 14. An electric telescopic rod 15 is fixed to one end of the adjustable telescopic arm 14. The telescopic end of the electric telescopic rod 15 faces downward and is detachably fixed to a connecting frame. A rectangular frame 16 is detachably fixed to the bottom of the connecting frame. Air suction cups 17 are detachably fixed at the four corners of the rectangular frame 16. The four air suction cups 17 are used to adsorb the four corners of the display screen plastic frame to achieve a stable adsorption and fixing effect. The four sides of the rectangular frame 16 can be telescopically adjusted. The rectangular frame 16 can be adjusted in size to correspond to display screen plastic frames of different sizes. The connecting frame can be replaced according to the specifications of the display screen plastic frame. The electric telescopic rod 15 is used to control the lifting and lowering of the rectangular frame 16. The adjustable telescopic arm 14 can be telescopically adjusted. The adjustable telescopic arm 14 can be rotated by a driving motor to achieve azimuth movement of the rectangular frame 16 .

[0036] For the above example, those skilled in the art should know that when implementing the above technical solution, the air suction cup 17 is connected to the existing vacuum generator and the corresponding air compressor through the air pipe.

[0037] In the present invention, the working principle of the device is as follows:

[0038] After the display screen frame is delivered to the middle plate 1, the first telescopic cylinder 8 is first activated and drives the movable plate 4 to move. The movable plate 4 pushes the display screen frame, causing it to move toward the front of the middle plate 1, and one side of the display screen frame abuts against the right-angle bending block 3. Then, the second telescopic cylinder 10 is activated and accurately pushes the positioning plate 11. The positioning plate 11 can push the display screen frame, causing it to move toward the left side of the display screen frame, and the other side of the display screen frame abuts against the right-angle bending block 3, thereby finally making the corner of the display screen frame abut against the right-angle bending block 3, and finally positioning the display screen frame. The positioning process can adapt to display screen frames of various specifications. The length and movement spacing of the movable plate 4 and the movement spacing of the positioning plate 11 enable display screen frames of various sizes within the space to be positioned and aligned. This effectively meets the subsequent assembly operations and can achieve a rapid positioning effect for the continuously transported display screen frames, with overall high work efficiency.

[0039] When the display screen plastic frame is transported to the middle plate 1, it is first transported from another production line via material conveyor belt 7 and then docked onto conveyor belt 2. This transports the display screen plastic frame onto conveyor belt 2, which then transports it to the center of the middle plate 1. At this point, the display screen plastic frame is in the middle area of the middle plate 1, ready for subsequent alignment operations. During docking, conveyor belt 2 is flush with the middle plate 1. After the transport operation, its height is lowered to the bottom of the middle plate 1.

[0040] After the alignment operation is completed, the electric telescopic rod 15 can be started. The electric telescopic rod 15 controls the rectangular frame 16 to descend, and the four air suction cups 17 adsorb the four corners of the display screen plastic frame. Then the electric telescopic rod 15 controls the rectangular frame 16 to rise, and the drive motor accurately controls the rotation of the adjustable telescopic arm 14, so that the rectangular frame 16 and the display screen plastic frame are moved to the corresponding installation station. The vertical rod 13 can slide and move, the adjustable telescopic arm 14 can be telescopically adjusted, and the four sides of the rectangular frame 16 can be telescopically adjusted. The rectangular frame 16 can be adjusted in size, and ultimately can meet the requirements of display screen plastic frames of different sizes. At the same time, the connecting frame can be replaced according to the specifications of the display screen plastic frame to meet the production needs of multiple batches. At the same time, the vertical rod 13 can slide and move and can also move the display screen plastic frame to multiple corresponding assembly spaces, that is, continuously move multiple display screen plastic frames to multiple assembly stations.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
