Description

Technical Field

[0001] This invention relates to the field of display screen manufacturing equipment, and more particularly to a display screen pressing device. Background Technology

[0002] In the manufacturing process of LED displays, the protective shell needs to be precisely pressed together. Patent application number CN202322986521.6 discloses a pressing machine for display processing, including a placement plate. A fixed platform is provided on the surface of the placement plate, and support frames are provided at both ends of the surface of the placement plate. A second motor is provided on the top of the support frames, and a rotating shaft is connected to the output end of the second motor. A second gear is connected to the top of the rotating shaft, and a first gear is meshed with one side of the second gear. A threaded sleeve is provided at the bottom of the first gear, and a threaded inner rod is threadedly connected inside the threaded sleeve. A pressing plate is provided at the bottom of the threaded inner rod, and an anti-slip pad is provided at the bottom of the pressing plate. This device presses the screen using the pressing plate. However, some screens have curved edges, and pressing the screen using the pressing plate cannot effectively press the curved edges of the screen.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display screen pressing device.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a display screen pressing device, comprising a base plate, a slide table disposed above the base plate, and multiple slide rails fixed on the base plate, the slide table being slidably connected to the slide rails. A feeding cylinder is also fixed on the base plate, the piston rod end of the feeding cylinder being fixed to the slide table. Fixing seats are symmetrically fixed on both sides of the slide table, each fixing seat having a fixing groove. A fixing plate is also fixed above the base plate, and a lifting cylinder is fixed on the fixing plate. A connecting plate is fixed to the piston rod end of the lifting cylinder, and a positioning plate is disposed below the connecting plate. The positioning plate is also fixed with multiple positioning rods, all of which pass through the connecting plate and are slidably connected to it. Each positioning rod has a positioning block fixed to its top. Multiple compressed positioning springs are also fixed between the positioning plate and the connecting plate. A lead screw and multiple sliding rods are provided below the positioning plate. The lead screw is driven to rotate by a pressure motor. A sliding plate is also provided below the positioning plate. The lead screw passes through the sliding plate and is threadedly connected to it. The sliding rods pass through the sliding plate and are slidably connected to it. A pressure rod is also fixed on the sliding plate, and a pressure roller is provided on the pressure rod. The screen to be pressed is placed in a fixed slot of a fixed base. The feeding cylinder is activated, and the piston rod on the feeding cylinder extends, moving the screen below the positioning plate. Another fixed slot is moved away from directly below the positioning plate, and the screen to be pressed is placed in this slot. The lifting cylinder is activated, and the connecting plate descends. The pressure roller descends with the connecting plate. After the pressure roller descends, the pressing motor drives the lead screw to rotate, and the slide moves in the direction of the lead screw. The pressure roller moves from one side of the screen to the other side to roll the screen. After the screen is pressed, the lifting cylinder is activated, and the piston rod on the lifting cylinder shortens, causing the pressure roller to rise and separate from the screen. The feeding cylinder is activated again, and the piston rod on the feeding cylinder shortens. The pressed screen moves with the slide table to one side below the positioning plate, and the screen to be pressed reaches the bottom of the positioning plate. This process is repeated. This device ensures all-around pressing of the screen by moving the pressure roller from one side to the other. Furthermore, by setting two fixed bases, the screen is moved to the bottom of the pressure roller for rolling in sequence, greatly improving the pressing efficiency of the screen.

[0007] Preferably, each of the fixing grooves has a top material groove at its bottom, and each top material groove has a top material plate. Multiple push rods are fixed to the top material plate, passing through and slidably connected to the slide table. A top material block is fixed to the bottom of each push rod, and a top material spring is fixed between the top material block and the slide table. Multiple top material cylinders are symmetrically fixed to both sides of the base plate, and push plates are provided on both sides above the base plate. The piston rod ends of the top material cylinders are fixed to the corresponding push plates. When the pressed screen reaches above the push plate, the corresponding top material cylinder is activated, its piston rod extends, the push plate rises, and after contacting the top material block, it pushes the top material block to move, causing the top material plate to rise. The top material plate lifts the pressed screen from the fixing groove, facilitating its removal.

[0008] Compared with existing technologies, the present invention has the following advantages:

[0009] This device rolls the screen from one side to the other using pressure rollers, ensuring full-range pressing of the screen. Furthermore, by setting two fixed seats, the screen is moved under the pressure rollers in sequence for rolling, greatly improving the screen pressing efficiency. Attached Figure Description
