[0002] Currently, conventional LCD screens require electrode pins to be connected to the electrodes of the driving circuit to apply a driving voltage signal to the LCD screen. Most of these connections are made using metal pins. At the client end, different client hosts require different pin lengths to accommodate insertion needs. Therefore, one of the steps in manufacturing an LCD screen is to cut the metal pins to the appropriate length. However, existing technologies have the following drawbacks: they lack a certain limiting and protective structure, which may cause the ends of the pins to break or the pins to bend and deform during the cutting process. Therefore, a pin cutting device for LCD screens is proposed to solve the above-mentioned problems. Utility Model Content

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a pin cutting device for a liquid crystal display screen, which has the following advantages:
[0015] The pin cutting device for this LCD screen, through the setting of a drive mechanism, a connecting mechanism, and a limiting mechanism, works as follows: When the electric push rod is activated, the output end extends downward, pushing the mounting plate downward. The support plate fixed at the top of the mounting plate slides within the rectangular hole at the top of the frame, serving as a guide to ensure the mounting plate descends smoothly. As the mounting plate moves downward, it drives the mounting frame, pressure plate, and cutting blade downward together. The pressure plate first contacts the top of the circular block. As the connecting mechanism continues to move downward, the pressure plate presses down on the circular block, causing the vertical plate to drive the slide block to move downward against the elastic force of the telescopic spring, thereby driving the sponge pressure block to move downward and press and fix the pins of the LCD screen. After the sponge pressure block has pressed the pins, the cutting blade continues to move downward, thus achieving the cutting of the pins. After the cutting is completed, the electric push rod drives the connecting mechanism to rise. Under the action of the telescopic spring, the slide block drives the sponge pressure block to rise and reset, achieving the purpose of having a limiting protection structure.

[0021] 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.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a pin cutting device for a liquid crystal display screen, including a base 1, a frame 2 fixedly installed on the top of the base 1, a partition 3 fixedly installed between the left and right sides of the inner wall of the base 1, and a rectangular groove 4 formed in the inner bottom wall of the base 1. The rectangular groove 4 provides space for the debris generated during the pin cutting process of the liquid crystal display screen, facilitating cleaning, and also plays a certain role in positioning the pins, so that the pins are in the appropriate position during cutting. The inner bottom wall of the base 1 has an installation groove that communicates with the left side of the inner wall of the rectangular groove 4. 5. The inner wall of the mounting slot 5 is open on the left side. A scale 10 extending to the left side of the base 1 is movably installed on the inner side of the mounting slot 5. The position of the LCD screen can be directly measured and adjusted by the scale 10 to ensure that the pins are in the correct cutting position and improve cutting accuracy. The top of the frame 2 is provided with a drive mechanism 6 extending to its inner side. The bottom of the drive mechanism 6 is provided with a connecting mechanism 7. The top of the partition 3 is provided with a limiting mechanism 8 extending to its bottom. The connecting mechanism 7 fits with the limiting mechanism 8. The bottom of the connecting mechanism 7 is provided with a cutting blade 9.
[0023] The partition 3 has a rectangular through hole located on the outside of the cutting blade 9, which provides space for the cutting blade 9 to move up and down, while preventing the cutting blade 9 from interfering with the partition 3. The base 1 has a U-shaped design.
[0024] The drive mechanism 6 includes an electric push rod 61. The top of the frame 2 is fixedly installed with an electric push rod 61 whose output end extends to the inside of the frame 2. The electric push rod 61 is electrically connected to an external power source and is controlled by an external program. The output end of the electric push rod 61 is fixedly installed with a mounting plate 62. The top of the mounting plate 62 is fixedly installed with a support plate 63 extending to the top of the frame 2.
[0025] The inner top wall of the frame 2 has rectangular holes that fit the support plates 63, and the two support plates 63 are symmetrically distributed.
[0026] The connecting mechanism 7 includes a mounting frame 71, the mounting frame 71 is fixedly mounted on the bottom of the mounting plate 62, pressure plates 72 are fixedly mounted on both the left and right sides of the mounting frame 71, and the cutting blade 9 is movably mounted on the bottom of the mounting frame 71.
[0027] Preferably, the limiting mechanism 8 includes a slide block 81. The slide block 81 extending to the top of the partition 3 is slidably installed at the bottom of the partition 3. A U-shaped plate 82 located outside the slide block 81 is fixedly installed at the top of the partition 3. A vertical plate 83 extending to the top of the U-shaped plate 82 is fixedly installed at the top of the slide block 81. A round block 84 is fixedly installed at the top of the vertical plate 83. The pressure plate 72 is in contact with the top of the round block 84. A telescopic spring 85 fixedly connected to the inner top wall of the U-shaped plate 82 is fixedly installed at the top of the slide block 81. The elastic coefficient of the telescopic spring 85 can be set according to requirements. After cutting, under the elastic force of the telescopic spring 85, the slide block drives the sponge pressure block 86 to rise and reset. A sponge pressure block 86 is fixedly installed at the bottom of the slide block 81. The sponge material has a certain degree of softness, which can avoid damage to the tube pin and effectively prevent the tube pin from breaking on both sides of the cutting point.
[0028] The partition 3 has a limiting hole that matches the slide 81. There are two sponge blocks 86, which are located on the left and right sides of the rectangular groove 4 respectively. The inner top wall of the U-shaped plate 82 has a limiting through hole that matches the vertical plate 83.
[0029] During use, place the LCD screen with the pin to be cut inside the base 1, so that the pin is above the rectangular groove 4 and between the two sponge blocks 86. The position of the LCD screen can be adjusted with the help of the scale 10 to ensure accurate pin cutting position. The scale 10 is movably installed in the mounting groove 5 and can be pulled out or retracted as needed. Check whether the electric push rod 61 is working properly, whether the cutting blade 9 is installed firmly, whether the sponge blocks 86 are clean and free of debris, and whether the connections of each component are loose, etc., to ensure that the device is in good working condition. Start the electric push rod 61. The output end of the electric push rod 61 extends downward, pushing the mounting plate 62 to move downward. The mounting plate 62 drives the connecting mechanism 7 and the cutting blade 9. Together, they move downwards. As the connecting mechanism 7 moves downwards, the pressure plate 72 contacts the round block 84 and presses the round block downwards, causing the slide 81 to move downwards against the elastic force of the telescopic spring 85, driving the sponge pressure block 86 downwards to press and fix the pins of the LCD screen. After the sponge pressure block 86 has pressed the pins, the cutting blade 9 continues to move downwards to cut the pins. After the cutting is completed, the electric push rod 61 resets, and the output end of the electric push rod 61 retracts upwards, driving the mounting plate 62, the connecting mechanism 7, and the cutting blade 9 to rise. Under the action of the telescopic spring 85, the slide 81 drives the sponge pressure block 86 to rise and reset. During operation, the operating procedures must be strictly followed to avoid damage to the device or injury to personnel due to improper operation.
[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0031] In summary, the pin cutting device for this LCD screen, through the setting of a drive mechanism 6, a connecting mechanism 7, and a limiting mechanism 8, when the electric push rod 61 is activated, the output end extends downward, pushing the mounting plate 62 downward. The support plate 63 fixed at the top of the mounting plate slides within the rectangular hole at the top of the frame 2, serving as a guide to ensure the mounting plate descends smoothly. When the mounting plate 62 moves downward, it drives the mounting frame 71, the pressure plate 72, and the cutting blade 9 downward together. The pressure plate 72 first contacts the top of the round block 84. As the connecting mechanism 7 continues to move downward, the pressure plate 72 presses down on the round block 84, causing the vertical plate 83 to drive the slide block 81. The tension spring 85 moves downward, which in turn moves the sponge block 86 downward to press and fix the pins of the LCD screen. After the sponge block 86 presses the pins, the cutting blade 9 continues to move downward to cut the pins. After the cutting is completed, the electric push rod 61 drives the connecting mechanism 7 to rise. Under the action of the tension spring 85, the slide 81 drives the sponge block 86 to rise and reset. This achieves the purpose of setting a limit protection structure and solves the problem that without a certain limit protection structure, the two ends of the pin cutting point may break or the pin may be bent and deformed during the cutting process.
