DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides Figure 1-Figure 6 An LCD cutting and mounting machine shown includes a workbench 1, which is used to control the equipment to perform cutting and mounting operations. A moving device 4 is fixedly installed on the top of the workbench 1. The moving device 4 is a common device composition in the prior art, including an electric cylinder, a slider and a slide rail, etc., which is used to drive the equipment fixed on its surface to move, which will not be described in detail here.

[0028] A gantry 2 is fixedly installed on the top of the workbench 1. The gantry 2 is used to provide a solid support frame for the control device 3. The control device 3 is slidably connected to the gantry 2. The control device 3 is composed of common equipment in the prior art, including an electric telescopic rod, an electric slider and a controller, etc., which are used to control the sliding and lifting of the cutting equipment on the gantry 2, which will not be elaborated here.

[0029] A cutting table 5 is fixedly mounted on the top of the mobile device 4, and the cutting table 5 is used to place the LCD display screen.

[0030] Specifically, a U-shaped baffle 6 is fixedly installed on the top of the cutting table 5, and the U-shaped baffle 6 is used to prevent the LCD display screen from deviating during cutting.

[0031] Furthermore, a patch mechanism is provided above the workbench 1 , and the patch mechanism includes a mounting seat 8 , and the mounting seat 8 is used to install equipment required for cutting and patching, and the mounting seat 8 is fixedly installed at the bottom of the control device 3 .

[0032] A knife seat 9 is fixedly mounted at the bottom of the mounting seat 8 . The knife seat 9 is used to mount a cutting knife 10 . The cutting knife 10 is used to cut polarizing films and LCD display screens. The cutting knife 10 is rotatably connected to the bottom of the knife seat 9 .

[0033] During operation, the LCD display screen is placed on the cutting table 5, the knife holder 9 is moved to the specified position by the control device 3, and then the cutting knife 10 is attached to the surface of the LCD display screen, and the moving device 4 is started. The moving device 4 pushes the cutting table 5 to move, so that the cutting knife 10 cuts the LCD display screen, thereby realizing the cutting of the LCD display screen.

[0034] Taking into account that the patch cannot be directly performed during the cutting process, the production efficiency and the degree of automation are reduced to a certain extent. Therefore, sliding grooves 11 are opened on both sides of the bottom of the mounting seat 8, and a spring 12 is arranged in the sliding groove 11. The spring 12 is used to make the roller 15 fit on the surface of the LCD display screen. One end of the spring 12 is fixedly connected to the sliding groove 11, and the other end of the spring 12 is fixedly connected to a push rod 13. The push rod 13 is used to install a bracket 14 that supports the rotation of the roller 15. The push rod 13 is slidably connected in the sliding groove 11.

[0035] Specifically, the bracket 14 is fixedly installed between the two push rods 13, and the roller 15 is rotatably connected to the bracket 14. The roller 15 is used to fit the polarizer to the LCD display screen, so that the polarizer and the LCD display screen fit more closely, and during the cutting process, the cutting knife applies the cutting force more evenly, thereby reducing the wear on the LCD display screen and improving the cutting accuracy.

[0036] A dustproof cloth 18 is fixedly sleeved on the roller 15 , and the dustproof cloth 18 is used to brush away dust that may be attached to the polarizer, and also can reduce the friction of the roller 15 on the polarizer.

[0037] Taking into account that when the LCD display screen is affixed with a polarizing film, the staff is required to align the polarizing film to the LCD display screen first, which not only increases the labor cost, but may also cause inaccurate alignment accuracy due to human factors. Therefore, an elastic block 7 is provided on the unclosed side of the U-shaped baffle 6 (that is, the opening of the U-shaped structure), and the elastic block 7 is used to clamp and fix the polarizing film. A rotating rod 16 is fixedly installed on both sides of the elastic block 7, and the rotating rod 16 is used for the elastic block 7 to rotate on the U-shaped baffle 6. The rotating rod 16 is rotatably connected to the U-shaped baffle 6. A torsion spring 17 is movablely sleeved on the rotating rod 16, and the torsion spring 17 is used for resetting the elastic block 7. One end of the torsion spring 17 is fixedly connected to the elastic block 7, and the other end of the torsion spring 17 is fixedly connected to the U-shaped baffle 6.

[0038] Specifically, the elastic stopper 7 is provided with rounded corners, which can better enable the elastic stopper 7 to rotate on the U-shaped stopper 6. It should be noted that the elastic stopper 7 needs to rotate because when cutting the LCD display screen, the cutting position will change with the specifications of the product.

[0039] During operation, the polarizer is clamped by the elastic stopper 7 in cooperation with the LCD display screen, thereby avoiding inaccurate alignment due to human factors.

[0040] Considering that the polarizer needs to be kept taut during the pasting process, a connecting rod 19 is provided above the cutting table 5. The connecting rod 19 is used to sleeve a roller support 20 that supports the polarizer. The connecting rod 19 is fixedly mounted on the gantry 2, and the roller support 20 is movably sleeved on the connecting rod 19.

[0041] During the specific operation, the polarizer is placed on the roller support 20, the roller 15 is attached to the surface of the polarizer, and the elastic block 7 cooperates with the LCD display screen to clamp one end of the polarizer. By implementing the operations in column 1, the LCD display screen after the patch is completed can be split while the patch is being pasted, thereby improving production efficiency and the degree of automation.
