Description

Technical Field

[0001] The utility model relates to the technical field of screen processing, in particular to a full-automatic LCD screen cutting machine. Background Art

[0002] With the wide application of LCD screens in the fields of mobile phones, tablet computers, televisions and automobiles, the cutting quality and efficiency of the processing equipment supporting them are increasingly valued by people. In the production and manufacturing of LCDs, in order to improve production efficiency, reduce manufacturing costs and form large-scale batch production, multiple LCDs are often made on a larger glass. There are multiple groups of LCD units on the glass after silk-screen printing. These small units must be separated before liquid crystal perfusion can be performed. The cutting process is to split the entire box of glass into monomers of the LCD. At present, the more common cutting processes include wheel cutting, laser cutting and water jet cutting. In the traditional cutting method, the display screen is generally limited by applying a local external force to the display screen, and the display screen is directly pressed and fixed. However, this limiting method is not only troublesome to operate, but also easy to damage the glass. Therefore, the negative pressure limiting method is often used now. However, in the existing negative pressure limiting method, since the number of negative pressure holes is fixed, the size of the negative pressure limiting glass cannot be adjusted, and the adaptability of actual use is poor. Summary of the invention

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a fully automatic LCD screen cutting machine. When in use, the cutting machine can adapt to glasses of different sizes through an adjustable negative pressure adsorption method, and has strong applicability. In addition, the vertical tube has a certain height, which is convenient for the subsequent removal of the cut glass.

[0006] Preferably, a plurality of supporting legs are installed at the lower end of the platform.

[0007] Preferably, the second slide rail and the two first slide rails are electric slide rails.

[0008] Preferably, the support mechanism comprises a plurality of vertical tubes connected to the upper end of the platform body, and the upper end of each vertical tube is fixedly connected to a rubber ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] A cavity, a vacuum pump, a vertical pipe and multiple second manual valves are provided. When negative pressure limiting is performed, it can be adjusted according to the actual size of the glass, thereby improving the actual adaptability. In addition, the vertical pipe has a certain height, which plays a certain supporting role on the cut glass. There is a gap at the lower end face of the glass for easy taking.

[0017] 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.

[0018] Reference Figure 1-Figure 3 , a fully automatic LCD screen cutting machine, comprising a table body 1, a plurality of supporting legs 2 are installed at the lower end of the table body 1;

[0019] Among them, it also includes a mobile cutting mechanism, which includes two first slide rails 3 installed on the front side of the platform body 1, and a first sliding seat 4 is installed in each of the two first slide rails 3 (specifically, the connection between the existing electric slide rail and the corresponding slide rail seat can be seen, which is a prior art and will not be specifically explained here, and the second slide rail 9 is the same), and the upper end of each first slide seat 4 is fixedly connected to a connecting column 6, and the upper ends of the two connecting columns 6 are commonly fixedly connected to a connecting bar 7, and the lower end of the connecting bar 7 is fixedly connected to a second slide rail 9, and a second slide seat is installed in the second slide rail 9, and the lower end of the second slide seat is fixedly connected to a hydraulic telescopic rod 10, and a cutting machine 11 is installed at the lower end of the hydraulic telescopic rod 10, and the second slide rail 9 and the two first slide rails 3 are all electric slide rails;

[0020] The supporting mechanism is also included. The supporting mechanism is located at the upper end of the platform 1. The supporting mechanism includes a plurality of vertical tubes 5 connected to the upper end of the platform 1. The upper end of each vertical tube 5 is fixedly connected to a rubber ring 8.

[0021] Among them, a cavity 12 is provided in the platform body 1, and the lower ends of multiple vertical pipes 5 extend into the cavity 12. A vacuum pump 13 is installed at the lower end of the platform body 1, and the air inlet end of the vacuum pump 13 extends into the cavity 12. An air inlet 14 is opened at the inner bottom of the cavity 12, and a first manual valve is installed in the air inlet 14. Second manual valves are installed in multiple vertical pipes 5.

[0022] In the present invention, when in use, the second manual valve on the corresponding vertical pipe 5 can be closed or opened according to the size of the screen glass to be cut, so that the rectangle formed by the vertical pipe 5 just corresponds to the size of the glass (or slightly smaller than the size of the glass), so that the stability of the subsequent limiting is better, and then the glass is placed on multiple corresponding vertical pipes 5;

[0023] Subsequently, the vacuum pump 13 is started to pump the cavity 12 to a negative pressure state (no need to pump it into a vacuum state). Under the effect of the negative pressure, the glass is limited on the vertical tube 5, and then the first slide rail 3, the second slide rail 9, the hydraulic telescopic rod 10 and the cutting machine 11 are started to realize the cutting work;

[0024] After the cutting is completed, the first manual valve in the air inlet 14 is opened, and the air pressure in the cavity 12 is restored to normal. At this time, the cut glass can be taken down. Since the vertical tube 5 has a certain height, it plays a certain supporting role for the cut glass. There is a gap at the lower end surface of the glass, which is convenient for taking.

[0025] It should be noted that, by providing the rubber ring 8, when placing the glass, the glass is in soft contact with the upper end surface of the vertical tube 5, so that it is not easy to cause damage to the glass when placing the glass. In addition, the use of the rubber ring 8 also makes the sealing between the glass and the upper end of the vertical tube 5 better, avoiding the situation where poor sealing of the contact surface leads to poor limiting effect.

[0026] 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.
