Description

Technical Field

[0001] This utility model relates to the field of glass substrate cutting technology for liquid crystal displays, specifically a glass substrate cutting device for liquid crystal display production. Background Technology

[0002] Glass substrate, also known as glass substrate, is a basic component of liquid crystal display devices. It is a thin glass sheet produced by float glass with an extremely flat surface. Glass substrate is one of the important raw materials for making liquid crystal panels.

[0003] Before glass substrates are put into use, they usually need to be cut from a single piece of glass to facilitate subsequent processing. As mentioned in the Chinese patent publication CN216919020U, a glass cutting device for LCD screen production: "A machine tool is provided with a processing platform for carrying the LCD screen; a cutting mechanism includes a gantry mounted on the machine tool that can move in a first direction, a moving table on the gantry that can move in a second direction, and a laser cutting head that can be lifted and lowered on the moving table. The LCD screen is transported to the processing platform of the machine tool using a loading mechanism, which can effectively improve the handling efficiency compared to manual handling."

[0004] Through the search of the above technologies, we found that after the glass substrate on the processing platform is cut, the cut glass substrate needs to be removed from the processing platform before the next glass substrate can be placed and cut. Since the removal and repositioning of the glass substrate will take a certain amount of time, the continuity of the cutting operation is poor, it is difficult to resume the cutting operation quickly, and it is difficult to improve the cutting efficiency of the glass substrate.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A glass substrate cutting device for LCD screen production includes a support platform 1 and a cutting assembly 15 disposed above the support platform 1. Two limiting plates 2 are fixed to the top of the support platform 1, and a feeding plate 3 is slidably connected between the two limiting plates 2. Two feeding grooves 6 are opened on the top of the feeding plate 3. Support legs 4 are fixed at the four corners of the bottom of the feeding plate 3. A positioning rod 9 is fixed to the top of the support leg 4 near the support platform 1. Positioning holes 16 are opened on the left and right sides of the support platform 1 at positions corresponding to the positioning rods 9. Magnets 17 are fixed on the inner walls of the positioning holes 16. The positioning rod 9 is an iron rod. When the positioning rod 9 is inserted to the end point inside the positioning hole 16, the positioning rod 9 and the magnet 17 are tightly attracted. When the positioning rod 9 is inserted into the positioning hole 16, it can attract the magnet 17, thereby improving the stability of the feeding plate 3 in a static state. On the other hand, the positioning rod 9 can restrict and position the moving position of the feeding plate 3. That is, when the positioning rod 9 on the bottom left side of the feeding plate 3 is inserted into the positioning hole 16 on the left side of the support platform 1, the feeding groove 6 on the top left side of the feeding plate 3 can be positioned at the top of the support platform 1 and below the cutting component 15. Conversely, when the positioning rod 9 on the bottom right side of the feeding plate 3 is inserted into the positioning hole 16 on the right side of the support platform 1, the feeding groove 6 on the top right side of the feeding plate 3 can be positioned at the top of the support platform 1 and below the cutting component 15.

[0027] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, a clamping assembly 7 is provided on one side of the inner wall of each feeding trough 6. The clamping assembly 7 includes an electric push rod 701 and a clamping plate 702. The electric push rod 701 is installed in the inner cavity of the feeding plate 3. The power output shaft of the electric push rod 701 is fixed in the middle of one side of the clamping plate 702. Two limiting rods 703 are fixed on one side of the clamping plate 702. The end of the limiting rod 703 away from the clamping plate 702 moves through the feeding plate 3. Silicone sheets 704 are glued and fixed on the other side of the clamping plate 702 and the other side of the inner wall of the feeding trough 6.

[0028] Specifically, by activating the electric push rod 701, its power output shaft can drive the clamping plate 702 to move inside the feeding groove 6, thereby clamping the glass substrate placed in the feeding groove 6 and ensuring the stability of the glass substrate during cutting. When the clamping plate 702 moves, it can be assisted by the limiting rod 703 to ensure the stability of the clamping plate 702 during movement. Silicone sheets 704 are fixed on one side of the clamping plate 702 and the inner wall of the feeding groove 6, which can protect the glass substrate when clamping it and avoid squeezing damage to the glass substrate.

[0029] Please see Figure 1 and Figure 4 In this embodiment, each support leg 2 4 is equipped with a roller 5 at its bottom, and support leg 1 101 is fixed at each of the four corners of the bottom of the support platform 1. The bottom of support leg 1 101 and the bottom of roller 5 are both attached to the bottom surface.

[0030] Specifically, the feeding plate 3 is supported by the second support leg 4 and slides through the roller 5, which can improve the stability of the feeding plate 3 and facilitate the smooth sliding of the feeding plate 3 on the support platform 1.

[0031] Please see Figure 1 and Figure 5 In this embodiment, limit sliders 301 are fixed on both the front and rear sides of the feeding plate 3, and limit grooves are opened on the side of the two limit plates 2 that are close to each other. The limit sliders 301 are slidably connected in the limit grooves, and handles 8 are fixed on both the left and right sides of the feeding plate 3.

[0032] Specifically, the feeding plate 3 has limit sliders 301 on both sides and is slidably connected in the limit groove of the limit plate 2, which can provide guidance for the movement of the feeding plate 3 and ensure the linear sliding of the feeding plate 3. Handles 8 are provided on both sides of the feeding plate 3 so that the feeding plate 3 can be easily pulled to move.

[0033] Please see Figure 1 and Figure 5In this embodiment, a sliding groove 10 is provided on the top of the support platform 1 at the position outside each limiting plate 2. A servo motor 11 is installed on one side of the support platform 1 at the position corresponding to one of the sliding grooves 10. The power output shaft of the servo motor 11 passes through the corresponding sliding groove 10 and is connected to a lead screw 12. A gate-shaped bracket 13 is slidably connected on the top of the support platform 1 at the position outside the two limiting plates 2. A slider is integrally formed on both sides of the bottom of the gate-shaped bracket 13. The two sliders are slidably connected in the two sliding grooves 10 respectively. One slider is threadedly sleeved with the lead screw 12 in the corresponding sliding groove 10, and the other slider is slidably sleeved with the fixed sliding rod 18 in the corresponding sliding groove 10.

[0034] Specifically, after the servo motor 11 is started, it can drive the lead screw 12 to rotate through its power output shaft, thereby causing the slider threaded with it to slide in the corresponding groove 10, thereby causing the portal frame 13 to move laterally on the support platform 1, and thus causing the cutting component 15 on the portal frame 13 to move laterally, so as to facilitate the lateral cutting of the glass substrate in the feeding groove 6. There is also a slider on the other side bottom of the portal frame 13. This slider is slidably fitted with the slide rod 18 fixed in the corresponding groove 10, which can improve the stability of the other side of the portal frame 13 and ensure the stable movement of the portal frame 13.

[0035] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the cutting assembly 15 is installed on the inner top wall of the portal frame 13. The cutting assembly 15 includes a movable block 1501, a movable plate 1502, and a laser cutting head 1503. The movable plate 1502 is fixed to the bottom of the movable block 1501, and the laser cutting head 1503 is installed on the top of the movable plate 1502. The movable block 1501 is slidably connected in the movable slot opened in the inner top wall of the portal frame 13. A servo motor 2 14 is installed on the top of one side of the portal frame 13. The power output shaft of the servo motor 2 14 moves through the movable slot and is connected to the lead screw 2 1401. The end of the lead screw 2 1401 away from the servo motor 2 14 is threaded through the movable block 1501 and rotatably connected to the inner wall of the movable slot.

[0036] Specifically, after the servo motor 14 is started, its power output shaft can drive the movable block 1501, which is threadedly fitted with it, to move in the movable groove on the inner top wall of the portal bracket 13, thereby driving the laser cutting head 1503 to move longitudinally on the inner top wall of the portal bracket 13, thus facilitating longitudinal cutting of the glass substrate in the feeding groove 6.

[0037] When using:

[0038] The liquid crystal display glass substrate to be cut is placed into the two feeding slots 6 respectively, and the electric push rod 701 is started. Its power output shaft pushes the clamping plate 702 to move, so that the glass substrate is clamped between the silicone sheet 704 on one side of the clamping plate 702 and the silicone sheet 704 on the inner wall of the feeding slot 6. Then, the servo motor 11 can be started to drive the gantry bracket 13 to move laterally, and the servo motor 14 can be started to drive the cutting assembly 15 to move longitudinally, so that the laser cutting head 1503 can cut the glass substrate in the feeding slot 6 on the top right side of the feeding plate 3.

[0039] like Figure 1 As shown, after the glass substrate in the feeding groove 6 on the top right of the feeding plate 3 is cut by the cutting assembly 15, the operator can pull the handle 8 on the right side of the feeding plate 3, thereby driving the entire feeding plate 3 to move to the right with the assistance of the second support leg 4 and the roller 5, until the feeding groove 6 on the top left of the feeding plate 3 carries the glass substrate to the bottom of the cutting assembly 15, and the positioning rods 9 on the two second support legs 4 on the bottom left of the feeding plate 3 are inserted into the two positioning holes 16 on the left side of the support table 1. When the positioning rods 9 are attracted to the magnets 17 in the positioning holes 16, the positioning of the glass substrate carried in the feeding groove 6 on the top left of the feeding plate 3 is completed. Then the laser cutting head 1503 can be used to cut the glass substrate in the feeding groove 6 on the top left of the feeding plate 3.

[0040] When cutting the glass substrate in the top left feeding slot 6 of the feeding plate 3, since the glass substrate in the top right feeding slot 6 of the feeding plate 3 has already been cut, the electric push rod 701 can be activated to release the clamping of the glass substrate. Then, the cut glass substrate can be taken out, and a new glass substrate to be cut can be placed in it and clamped using the clamping assembly 7. After that, wait for the glass substrate in the top left feeding slot 6 of the feeding plate 3 to finish cutting. After that, the feeding plate 3 can be pushed directly to transfer the glass substrate in the top right feeding slot 6 of the feeding plate 3 to the bottom of the cutting assembly 15 for cutting. By repeating the above operation, the glass substrate to be cut can be transferred to the bottom of the cutting assembly 15 in both feeding slots 6. That is, when cutting the glass substrate in one feeding slot 6, the cut glass substrate can be taken out and the glass substrate to be cut can be placed in the other feeding slot 6. The two do not affect each other, and the cutting operation is more continuous.

[0041] It should be noted that the electric actuator 701, servo motor 11, servo motor 2 14 and laser cutting head 1503 are all common knowledge in the field, and their working principles are well-known technologies. The specific model and specifications can be selected and determined according to the device and actual conditions, so they will not be described in detail here.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
