[0001] The utility model relates to the technical field of workstation transfer, in particular to a workstation transfer device for a liquid crystal display screen. Background Art

[0002] Liquid crystal display is a type of display used in digital watches and many portable computers. LCD displays use two sheets of polarized material with a liquid crystal solution between them. When an electric current is passed through the liquid, the crystals rearrange themselves so that light cannot pass through them. Each crystal acts like a shutter, either allowing light to pass through or blocking it.

[0003] After the LCD screen is produced, it needs to be tested. However, the current transfer device requires the staff to remove the display screen from the test table and put it into the storage frame after completing the test on a display screen. Then, the next screen is tested. The process is repeated continuously, which increases the labor intensity of the staff, affects production efficiency, and increases product costs.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A workstation transfer device for a liquid crystal display screen comprises an operating table 1, a second slide groove 18 is symmetrically opened at the top of the operating table 1, and a support plate 2 is slidably connected to the inner wall of each second slide groove 18, and two support plates 2 are fixedly connected to a top plate 3, and a first hydraulic push rod 4 is fixedly connected to the top of the top plate 3. The movable end of the first hydraulic push rod 4 penetrates through the side wall of the top plate 3 and is rotatably connected to the mounting plate 5, and a first slide groove 7 is opened at the bottom end of the mounting plate 5. A motor 6 is fixedly connected to the side wall of the mounting plate 5, and the motor 6 is a forward and reverse motor. A bidirectional lead screw 8 is fixedly connected to the output end of the motor 6, and one end of the bidirectional lead screw 8 penetrates through the side wall of the mounting plate 5 and is rotatably connected to the inner wall of the first slide groove 7, and the side wall of the bidirectional lead screw 8 is symmetrically threaded with connecting rods 9, and one end of each connecting rod 9 is fixedly connected to a clamping plate 10.

[0021] The inner wall of the clamping plate 10 is elastically connected to the pressure plate 12 through the spring 11, and the second hydraulic push rods 19 are symmetrically fixedly connected to the top of the operating table 1. The movable end of each second hydraulic push rod 19 is fixedly connected to the corresponding side wall of the support plate 2. The support plate 2 is driven by the second hydraulic push rod 19, so that the display screen is moved above the storage frame 17.

[0022] A rotating rod 14 is fixedly connected to the side wall of the mounting plate 5, and a cylindrical gear 15 is fixedly connected to the side wall at one end of the rotating rod 14. A rack plate 16 is fixedly connected to the side wall of one of the support plates 2. A part of the rack plate 16 is provided with a rack, so that when the first hydraulic push rod 4 drives the mounting plate 5 to move upward, it will not immediately rotate to a vertical state, so that the mounting plate 5 drives the display screen to move above the storage frame 17 and then rotates to a vertical state. The rack plate 16 is meshed with the cylindrical gear 15. When the cylindrical gear 15 is meshed with the rack part of the rack plate 16, the meshing relationship between the rack plate 16 and the cylindrical gear 15 allows the mounting plate 5 to drive the clamping plate 10 to rotate 90 degrees.

[0023] A detection table 13 is fixedly connected to the top of the operation table 1. The display screen to be inspected is placed on the detection table 13 for quality inspection. A storage frame 17 is fixedly connected to the top of the operation table 1. When the display screen is in a vertical state, the storage frame 17 is located below the display screen and will not cause the display screen to move above the storage frame 17. The display screen is vertically placed into the storage frame 17, which is convenient for taking out and makes rational use of space.

[0024] One end of the spring 11 is fixedly connected to the inner wall of the clamping plate 10, and the other end of the spring 11 is fixedly connected to the pressing plate 12. The display screen is buffered and clamped by the spring 11 to avoid damage to the display screen caused by excessive clamping.

[0025] Each connecting rod 9 abuts against and slides along the inner wall of the first chute 7, so that the connecting rods 9 move towards each other in the horizontal direction. The connecting rod 9 has an inverted L-shaped structure, and the clamping plate 10 has an inverted U-shaped structure. The U-shaped clamping plate 10 can better clamp the display screen.

[0026] In the present utility model, first, the display screen to be inspected is placed on the detection table 13. After the inspection is completed, the first hydraulic push rod 4 is started to make the clamping plate 10 at the same horizontal height as the display screen. The motor 6 is started. The motor 6 is a forward and reverse motor. By the forward rotation of the motor 6, the bidirectional lead screw 8 is driven to rotate, so that the two connecting rods 9 approach each other in the horizontal direction to clamp the display screen. The pressing plate 12 is elastically connected to the inside of the clamping plate 10 through the spring 11 to buffer and clamp the display screen, avoiding damage to the display screen caused by excessive clamping. The display screen is fixedly clamped by driving the clamping plate 10 through the bidirectional lead screw 8, which can be applied to display screens of different sizes, and subsequent storage operations are carried out. The operation is convenient and fast, avoiding collisions during manual handling and storage, causing product damage, saving handling time, reducing human errors, and saving costs;

[0027] After the display screen is fixedly clamped, the first hydraulic push rod 4 is started. The mounting plate 5 is driven to move upward by the first hydraulic push rod 4. When the cylindrical gear 15 meshes with the rack part of the rack plate 16, due to the meshing relationship between the rack plate 16 and the cylindrical gear 15, the mounting plate 5 drives the clamping plate 10 to rotate 90 degrees, so that the display screen can be vertically placed into the storage frame 17, which is convenient for taking out and makes rational use of space; when the display screen is in a vertical state, the second hydraulic push rod 19 drives the support plate 2, so that the display screen moves above the storage frame 17. After moving above the storage frame 17, the motor 6 rotates in reverse, so that the clamping plates 10 move away from each other to release the clamping of the display screen. The staff puts the display screen into the storage frame 17. This device can avoid repetitive operations by workers, reduce the work intensity, and improve the production efficiency.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
