Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display screen separation technology, and in particular to a separation device for liquid crystal display screens. Background Technology

[0002] A liquid crystal display (LCD) screen is a flat, ultra-thin display device that utilizes the optical properties of liquid crystal materials to change the light transmittance by controlling an electric field, thereby achieving image display. An LCD screen mainly consists of a backlight panel, a lower polarizer, a liquid crystal substrate, an upper polarizer, and a color filter. During the production and maintenance of LCD screens, it is often necessary to separate the LCD screen, that is, to separate the glass substrate of the LCD screen from the thin-film transistor (TFT) layer or other functional layers.

[0003] Traditional methods for separating LCD screens often involve manual operation, which is not only inefficient but also prone to damaging the LCD screen, affecting product quality and yield. Therefore, we propose a separation device for LCD screens to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing LCD screen separation methods, which mostly rely on manual operation, resulting in low efficiency and potential damage to the LCD screen. Therefore, this invention proposes a separation device for LCD screens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A separation device for an LCD screen includes a base, a separation plate fixedly mounted on the top of the base, a PLC controller fixedly mounted on one side of the base, a placement block fixedly mounted on the top of the separation plate, two symmetrically formed sliding grooves on the top of the separation plate, the two sliding grooves being slidably connected to the same movable frame, the placement block being displaced between the two sliding grooves, and a protective shell fixedly mounted on the top of the movable frame. The separation device also includes:

[0007] A separation component, which is mounted on a movable frame, is used for automatic separation of the LCD screen;

[0008] A fixing component is mounted on the placement block and is used to fix the LCD screen during the LCD screen separation operation.

[0009] In one possible design, the separation assembly includes two rotating rods symmetrically arranged on the top inner wall of the movable frame. Both rotating rods are rotatably connected to the movable frame. The tops of the two rotating rods penetrate the movable frame and extend into the interior of the protective shell. The outer walls of the two rotating rods are fixedly fitted with pulleys inside the protective shell. The two pulleys are driven by the same belt. A first motor is fixedly installed on the top of the protective shell. The output end of the first motor penetrates the protective shell and is fixedly connected to one of the rotating rods. A storage wheel is fixedly fitted on both rotating rods, and the storage wheel is located inside the movable frame. The same cutting wire is wound on the two storage wheels.

[0010] In one possible design, the top of the movable frame has two positioning holes, each containing a limiting screw. A limiting ring is fixedly fitted onto each limiting screw, and a spring is fitted onto each limiting screw. The top and bottom of each spring abut against the top of the corresponding limiting ring and the inner wall of the top of the movable frame. Nuts for limiting are threaded onto each limiting screw located above the movable frame, and both nuts are in contact with the top of the movable frame. Guide wheels are rotatably connected to the bottom of each limiting screw, and the cutting wire rests on the two guide wheels.

[0011] In one possible design, a slide rod is rotatably connected inside one of the slide grooves, and the movable frame passes through the slide rod and is slidably connected to the slide rod. A threaded rod is rotatably connected inside the other slide groove, and the threaded rod is threaded through the movable frame. A driven gear is fixedly sleeved on the upper part of the threaded rod. A second motor is fixedly installed at the bottom of the separating plate, and a driving gear is fixedly sleeved at the output end of the second motor. The driving gear meshes with the driven gear.

[0012] In one possible design, the fixing assembly includes two negative pressure pumps, both of which are fixedly mounted on the bottom inner wall of the base. The placement block has a negative pressure chamber inside, and the air inlets of the two negative pressure pumps are connected to the negative pressure chamber through pipes. The top of the placement block has multiple negative pressure holes that are connected to the negative pressure chamber.

[0013] In one possible design, the placement block is internally equipped with a heating wire for heating.

[0014] In one possible design, the top of the placement block is provided with a soft pad made of silicone material.

[0015] In this application,

[0016] First, the LCD screen to be separated is placed on the placement block. The negative pressure pump is started by the PLC controller. The negative pressure pump generates a negative pressure adsorption force on the LCD screen through the negative pressure chamber and negative pressure hole, which firmly fixes the LCD screen on the placement block. The soft and high-temperature resistant silicone pad on the placement block can make the LCD screen fit more tightly with the placement block, improving the negative pressure effect of the negative pressure pump. At this time, the placement block can be heated by the heating wire inside the placement block as needed, so that the LCD screen placed on the placement block is heated, thereby improving the subsequent separation effect of the LCD screen.

[0017] Then, the first motor is started by the PLC controller. The forward and reverse rotation of the first motor drives one of the rotating rods to rotate in both directions. Through the transmission action of two pulleys and belts, the other rotating rod rotates synchronously. The receiving wheels on the two rotating rods rotate accordingly, so that the cutting wire on the two receiving wheels winds back and forth on the two receiving wheels. The reciprocating movement of the cutting wire separates the LCD screen. At the same time, the setting of the limit screw and spring can ensure the stability and tension of the cutting wire during the cutting process.

[0018] During the cutting process, the second motor starts, driving the thread to rotate. Through the threaded rod and with the guidance of the slide rod, the moving frame moves smoothly in the slide groove, realizing the separation of the LCD screen.

[0019] Beneficial effects: The separation device for LCD screens described in this utility model achieves rapid and accurate separation of LCD screens through the design of automated separation components and fixing components, which greatly improves separation efficiency and product quality.

[0020] In this utility model, the separation device for LCD screens uses a motor-driven pulley and a receiving wheel to cut and separate the LCD screen using a cutting wire. It is easy to operate, has a good separation effect, and the cutting wire is easy to replace and maintain.

[0021] In this utility model, the separation device for LCD screens uses a sliding rod and a threaded rod to achieve smooth movement and precise positioning on the separation plate, thereby further improving separation accuracy and efficiency.

[0022] In this invention, the design of automated separation and fixing components enables rapid and accurate separation of LCD screens, improving separation efficiency and product quality. The separation component uses a motor-driven pulley and a collection wheel, and uses a cutting wire to cut and separate the LCD screen. The operation is simple, the separation effect is good, and the cutting wire is easy to replace and maintain. The moving frame achieves stable movement and precise positioning on the separation plate through the cooperation of a sliding rod and a threaded rod. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figure 1-3 A separation device includes a base 1, a separation plate 2 fixedly mounted on the top of the base 1, a PLC controller 3 fixedly mounted on one side of the base 1, and a placement block 4 fixedly mounted on the top of the separation plate 2 for placing the LCD screen to be separated. Two symmetrical sliding grooves are formed on the top of the separation plate 2, and the two grooves are slidably connected to the same movable frame 5, allowing the movable frame 5 to slide along the grooves on the separation plate 2. The placement block 4 is located between the two sliding grooves, and a protective shell 6 is fixedly mounted on the top of the movable frame 5 to protect the internal separation components.

[0030] Furthermore, the separation device also includes a separation component and a fixing component. The separation component is mounted on the movable frame 5 and is used for automatic separation of the LCD screen. Specifically, the separation component includes two rotating rods 9, which are symmetrically arranged on the top inner wall of the movable frame 5 and rotatably connected to the movable frame 5. The tops of the two rotating rods 9 penetrate the movable frame 5 and extend into the interior of the protective shell 6. The outer walls of the two rotating rods 9 are each fixedly fitted with pulleys 10 inside the protective shell 6. The two pulleys 10 are driven by the same belt 11, allowing the two rotating rods 9 to rotate synchronously. A first motor 17 capable of rotating in both directions is fixedly mounted on the top of the protective shell 6. The output end of the first motor 17 penetrates the protective shell 6 and is fixedly connected to one of the rotating rods 9, driving the rotating rod 9 to rotate. Each of the two rotating rods 9 is fixedly fitted with a storage wheel 12, and the storage wheel 12 is located inside the moving frame 5. The same cutting wire 13 is wound around the two storage wheels 12. When the first motor 17 rotates in both directions, it drives the two rotating rods 9 to rotate accordingly. The cutting wire 13 is wound back and forth on the two storage wheels 12, so that the cutting wire 13 moves back and forth, thereby cutting the LCD screen.

[0031] To ensure stable movement of the cutting wire 13, two positioning holes are provided at the top of the moving frame 5. Each positioning hole contains a limiting screw 14, and a limiting ring is fixedly fitted onto each limiting screw 14 to prevent it from falling out of the positioning hole. A spring 16 is fitted onto each limiting screw 14, with its top and bottom abutting against the top of the corresponding limiting ring and the inner wall of the top of the moving frame 5, providing elastic support for the limiting screw 14. Nuts are threaded onto each limiting screw 14 above the moving frame 5, and both nuts contact the top of the moving frame 5 to secure the limiting screw 14. Guide wheels 15 are rotatably connected to the bottom of each limiting screw 14, and the cutting wire 13 rests on the two guide wheels 15 to ensure stable movement of the cutting wire 13.

[0032] To drive the movable frame 5 to move and achieve the overall separation of the LCD screen, a sliding rod 7 is rotatably connected inside one of the slide grooves. The movable frame 5 passes through the sliding rod 7 and is slidably connected to it, allowing the movable frame 5 to slide along the sliding rod 7. A threaded rod 8 is rotatably connected inside the other slide groove. The threaded rod 8 is threaded through the movable frame 5. When the threaded rod 8 rotates, it can drive the movable frame 5 to move along the slide groove. A driven gear 18 is fixedly sleeved on the upper part of the threaded rod 8. A second motor 19 is fixedly installed at the bottom of the separation plate 2. A driving gear 20 is fixedly sleeved on the output end of the second motor 19. The driving gear 20 meshes with the driven gear 18 to drive the threaded rod 8 to rotate.

[0033] This application can be used in the field of LCD screen separation technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 2-3 Based on Embodiment 1, an improvement is made to a separation device for LCD screens, which is applied to the field of LCD screen separation technology. A fixing component is mounted on a placement block 4 to fix the LCD screen during separation operations. Specifically, the fixing component includes two negative pressure pumps 21, both of which are fixedly mounted on the bottom inner wall of the base 1. A negative pressure chamber 401 is formed inside the placement block 4, and the air inlets of both negative pressure pumps 21 are connected to the negative pressure chamber 401 via pipes. Multiple negative pressure holes 402 are formed on the top of the placement block 4, communicating with the negative pressure chamber 401. When the negative pressure pumps 21 are working, the LCD screen can be adsorbed and fixed through the negative pressure holes 402.

[0035] To further improve the separation effect of the LCD screen, the placement block 4 is equipped with a heating wire 403 for heating, which can improve the separation effect between the LCD screen and the glass substrate. At the same time, a silicone pad 22 is provided on the top of the placement block 4 to protect the LCD screen from damage during the separation process.

They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
