Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary coating equipment, in particular to a display screen auxiliary coating equipment for processing and producing an LED display screen. Background Art

[0002] During the production of LED display screens, auxiliary lamination is required. The laminating material is polyester film or polycarbonate film. The surface of the film can be frosted after treatment, which has the effect of reducing reflection and refraction and improving the visual comfort of the display screen. During the auxiliary lamination, the display screen is usually transmitted. During the transmission process, the rolled film is manually pulled and placed at one end of the display screen. After transmission, the film is attached to the display screen to achieve the auxiliary lamination effect.

[0003] However, during the lamination process, since the display screen is in a linear moving state, the winding rod for placing the film and the display screen need to be at the same width. When laminating display screens of different widths, the film winding rod corresponding to the width needs to be replaced. After the winding rod is replaced, due to the different widths, the position of the winding rod is easy to slide during rotation, resulting in movement and misalignment with the display screen, affecting the accuracy of the lamination. After the lamination is completed, the film needs to be cut. Since the film is laminated during the movement process, the display screen drives the film to move when the blade slides, which easily causes the cutting position to tilt, and the incision is not smooth and needs to be corrected later.

The laminating mechanism 1 is embedded in the upper end of the machine 4, and the conveyor belt 5 is installed on the upper end of the machine 4. The cabinet door 3 is hinged and engaged with the side of the machine 4, and the exhaust plate 2 is embedded in the side of the machine 4. The laminating mechanism 1 is connected to the internal circuit of the machine 4.

During laminating, the display screen moves horizontally and linearly on the conveyor belt 5 at the upper end of the machine 4, and the laminating mechanism 1 laminates the display screen.

[0022] The laminating mechanism 1 is provided with a cutting mechanism 11, a motor 12, a transmission rod 13, a winding mechanism 14, and a fixed plate 15. The motor 12 is engaged in the fixed plate 15, the cutting mechanism 11 is installed in the fixed plate 15, the transmission rod 13 and the motor 12 are threaded and movable, the transmission rod 13 and the winding mechanism 14 are threaded and matched, the winding mechanism 14 is movably engaged in the fixed plate 15, the fixed plate 15 is embedded in the upper end of the machine table 4, the motor 12 is connected to the internal circuit of the machine table 4, a control screen is provided on the outer side of the fixed plate 15, the cutting mechanism 11 is in a hollow state, and the outer side can be moved, so that the replaced film is placed on the winding mechanism 14, the motor 12 is controlled to rotate, and the winding mechanism 14 is driven to rotate through the transmission rod 13, so as to assist in spreading the film, and at the same time, according to the moving speed of the conveyor belt 5, the interval of the cutting of the film of the upper winding mechanism 14 by the cutting mechanism 11 is adjusted to achieve the auxiliary laminating effect.

[0023] The winding mechanism 14 is provided with a rotating rod w1, a fixing ring w2, a sliding tube w3, and a winding plate w4. The fixing ring w2 is engaged with the outer side of the rotating rod w1, and the side surface of the winding plate w4 is slidably matched with the side surface of the fixing ring w2. The winding plate w4 is embedded in the outer side of the sliding tube w3, and the sliding tube w3 is limited and moved on the outer side of the rotating rod w1. The transmission rod 13 is threadedly matched with the left end of the rotating rod w1, and the rotating rod w1 is movably engaged with the inside of the fixing plate 15. Four arc-shaped rods are provided on the inner side of the sliding tube w3, and are evenly distributed in an annular shape. Four parallel grooves are provided on the outer side of the rotating rod w1, which correspond to the four arc-shaped rods on the sliding tube w3, and then the sliding tube w3 enters from the side of the rotating rod w1. After adjusting to the position above the display screen, the fixing ring w2 is manually pushed to slide and fix outside the rotating rod w1. Then, when the sliding tube w3 follows the rotating rod w1 to rotate, the position of the winding plate w4 is fixed, so as to prevent the winding plate w4 from easily rotating and moving on the rotating rod w1.

[0024] The fixing ring w2 is provided with a ball w21, a support ring w22, an elastic plate w23, a sphere w24, and a clamping plate w25.

The upper end of the clamping plate w25 is provided with two square grooves, which cooperate with the ball w21, so as to fix the ring. When w2 moves to the side of the winding plate w4 and contacts it, the elastic plate w23 and the locking plate w25 move along with it. During the movement, the locking plate w25 squeezes the ball w21, and the locking plate w25 is compressed inwardly under the elastic deformation of the elastic plate w23. When the support ring w22 stops, the ball w21 is locked in the groove at the upper end of the locking plate w25, and the locking plate w25 is fixed in position by the ball w21.

The connecting plate t3 is installed inside the fixing plate 15. The cutter t2 is connected to the internal pipeline of the machine table 4. A blade is provided on the upper end of the cutter t2. The cutter t2 is pneumatically translated through the connection of the pipeline. A sphere is provided at one end of the limit rod t4, which can be fan-shaped tilted at a fixed position. A semicircular rod is provided inside the engaging groove t1, and the interval between the semicircular rods is mutually engaged with the inner side of the connecting rod t5, so that the connecting rod t5 is manually pulled to change the position of the connecting rod t5 on the engaging groove t1, and then the inclination of the limit rod t4 is adjusted. When the display screen moves, the cutter t2 in the inclined moving state cuts the film, so that the movement of the display screen and the movement of the cutter t2 cooperate with each other to cut the film, so that the cutting of the film is in a flat state, preventing the cut film from tilting and needing correction.

[0026] Working principle:

[0027] 1. In the utility model, the cabinet door 3 can open and close the inside of the machine 4, and the inside of the machine 4 is cooled by the exhaust plate 2.

The motor 12 is controlled to rotate, and the winding mechanism 14 is driven to rotate through the transmission rod 13, thereby assisting in spreading the film. At the same time, according to the moving speed of the conveyor belt 5, the interval at which the cutting mechanism 11 cuts the film of the upper winding mechanism 14 is adjusted to achieve an auxiliary lamination effect.

[0028] 2. The replaced film in the utility model is placed on the outside of the winding plate w4. After replacement, the sliding tube w3 enters from the side of the rotating rod w1.

When the supporting ring w22 stops, the ball w21 is engaged in the groove at the upper end of the locking plate w25, and the locking plate w25 is fixed in position by the ball w21. Then, after the winding plate w4 moves to the position above the display screen, it is fixed in position by the fixing ring w2 to prevent it from sliding easily during rotation and being misaligned with the display screen.

[0029] 3. In the utility model, the connecting rod t5 is manually pulled to change the position of the connecting rod t5 on the engaging groove t1, and then the inclination of the limit rod t4 is adjusted. When the display screen moves, the cutter t2 in the inclined moving state cuts the film, so that the movement of the display screen and the movement of the cutter t2 cooperate with each other to cut the film in a flat state, thereby preventing the cut film from tilting and needing correction.
