Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically to an LED display screen laminating machine. Background Technology

[0002] A laminating machine comprises major mechanical parts such as an unwinding device, an adhesive coating device, a conveying and pressurizing device, and a drive motor. Fully automatic laminating machines are primarily designed for the production characteristics of small displays and small touch components, and are an essential piece of equipment in LCD manufacturing.

[0003] Patent CN221967834U discloses an LED display bonding machine, which includes a bonding box, a placement stage, a sliding block a, and a sliding block b. The placement stage is laterally slidably mounted on the bonding box, and the bonding box is provided with a guide mechanism that drives the placement stage to slide laterally. This device can achieve micro-adjustments in multiple directions to ensure precise bonding of LED modules. By fine-tuning the angle of the bonding device, the gaps and misalignments between modules can be minimized, and the position and angle of each LED module can be ensured to meet the design requirements.

[0004] However, the device only has a placement platform to limit the placement of the LED module, but no placement platform for the display screen. This means that after the display screen is attracted by the rubber suction cup, it is necessary to continuously adjust the position of the display screen with the LED module by cooperating with structures such as motor a and motor B. The operation is cumbersome and greatly reduces the display screen bonding efficiency. To address this issue, an LED display screen bonding machine is proposed to solve the problem that the existing display screen bonding machines cannot bond the display screen conveniently and stably.

[0015] (III) Beneficial Effects

[0016] 1. This LED display bonding machine places the display screen on an external placement platform. After being limited by a scale and a limiting mechanism, the servo motor drives the gears on the outside of the rotating shaft, which in turn drive the moving plate to move the display screen into the fixed frame. The hydraulic telescopic column moves the suction cup downward. The vacuum pump is turned on to create a vacuum in the suction cup through the vacuum pipe, adsorbing the display screen and moving it upward. During the process, the LED module is placed on the upper limit of the empty placement platform and then moved into the fixed frame. This allows for precise bonding of the display screen, solving the problem that existing display screen bonding machines are difficult to bond display screens conveniently and stably.

When the LED display laminating machine moves the LED module or display screen by a servo motor-driven moving plate, the height of the lifting frame is adjusted by the electric telescopic rod at the bottom of the fixed plate, so that the roller brushes on both sides are respectively bonded to the top of the LED module and the display screen. At the same time, the motor is turned on to drive the roller brushes to rotate outward of the fixed frame. Then, the dust pump is turned on, and with the help of the connecting pipe and dust suction hole, all the dust brushed off by the roller brushes can be sucked into the dust collection box by the dust suction base, thus improving the functionality of this LED display laminating machine.

[0025] Furthermore, the movable plate 5 passes through the fixed frame 2 and the two are slidably connected. The air extraction pipe 15 is interconnected with the air extraction pump 14 and the suction cup 4. The zero mark of the scale coincides with the axis of the placement platform 6.

[0026] Furthermore, the output shaft of the servo motor 13 extends through the inner cavity of the groove 9 and is fixedly connected to the rotating shaft 11, and the gear 10 meshes with the rack 12.

[0027] Furthermore, the limiting mechanism 7 includes electric push rods 701 that are symmetrically and fixedly connected to the top of the placement platform 6. A limiting plate 702 is fixedly connected to one side of the electric push rod 701. After the display screen or LED module is placed on the placement platform 6, it is precisely positioned in the middle of the top of the placement platform 6 according to the size of the display screen or LED module and the scale. Then, the electric push rod 701 is activated to drive the limiting plate 702 to fit with the boundary of the display screen or LED module, thereby achieving the purpose of precise positioning of the display screen or LED module and improving the fitting accuracy and stability.

[0028] Furthermore, the dust removal mechanism 8 includes a lifting frame 801 slidably connected to both sides of the fixed frame 2. A roller brush 802 is rotatably connected to the inner cavity of the lifting frame 801. A motor 803 is fixedly connected to one end of the lifting frame 801.

[0030] Furthermore, a dust collection box 807 is fixedly connected to one end of the fixed frame 2, and a vacuum pump 808 is fixedly connected to the top of the dust collection box 807. A connecting pipe 809 is provided on the top of the vacuum pump 808, and the connecting pipe 809 communicates with the vacuum base 806.

The vacuum pump 14 is turned on and the vacuum pipe 15 is used to evacuate the suction cup 4 to adsorb the display screen and move it up. During the process, the LED module is placed on the upper limit of the empty placement platform 6 and then moved into the fixed frame 2. The LED module can then be moved down to accurately bond the display screen, which solves the problem that existing display bonding machines are difficult to bond display screens conveniently and stably.
