Description

Technical Field

[0001] This utility model relates to the field of ribbon cable cutting and positioning devices, and in particular to a ribbon cable cutting and positioning device for LCD screen production. Background Technology

[0002] A ribbon cable cutting and positioning device for LCD screen production is mainly used in the ribbon cable processing stage of LCD screen production. It is used to accurately position and cut the ribbon cables, ensuring that the cut cable length meets assembly requirements. LCD screen ribbon cables are mostly arranged in a single row, and cables at different positions need to be cut to different lengths. However, the cutting shears equipped in the device are mostly of a single-piece structure, which cannot simultaneously accommodate the cutting needs of ribbon cables of different lengths.

[0003] To address the positioning and accuracy requirements of ribbon cable cutting, existing technologies have optimized the device. Some structures add positioning slots on the table to fix the ribbon cable position and reduce cutting offset. Others improve the sharpness of the cutting blades to enhance the flatness of the cut surface. Still others enhance cutting stability by using an electrically driven blade holder. These improvements mainly focus on positioning accuracy and cutting quality, solving only a single aspect of the problem. They do not optimize the compatibility of the integral cutting blades with ribbon cables of different lengths, and multiple operations are still required to complete the cutting.

[0004] Existing ribbon cable cutting and positioning devices for LCD screen production have significant drawbacks. The integrated cutting shears cannot simultaneously cover and cut ribbon cables of varying lengths within a single row. Operators must repeatedly adjust the cable positions or move the cutter holder to cut cables of different lengths sequentially, making the entire process cumbersome and time-consuming. Multiple cuts can also lead to inconsistent length accuracy among different ribbon cables due to positioning reference deviations, affecting subsequent assembly compatibility with the LCD screen. Especially in mass production of ribbon cables, multiple cuts significantly reduce processing efficiency and fail to meet the demands for efficient and precise ribbon cable cutting. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a ribbon cable cutting and positioning device for LCD screen production. It aims to solve the problems of existing integral cutting shears, which are difficult to cut ribbon cables of different lengths at once, require multiple adjustments for cutting, are cumbersome and time-consuming, are prone to poor accuracy due to positioning deviations, have low batch efficiency, and are difficult to meet the requirements of efficient and accurate cutting.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cable trimming and positioning device for LCD screen production, comprising a cable trimming table, a size segmentation mechanism and a positioning auxiliary mechanism being provided at the top of the cable trimming table, the size segmentation mechanism comprising a main support column, the bottom end of the main support column being fixedly connected to the top of the cable trimming table, an operating table being fixedly connected to the top of the main support column, a locking groove being provided in the inner wall of the operating table, a sliding groove being provided in the inner wall of the operating table, a T-shaped slide rail being slidably connected to the inner wall of the sliding groove, a bottom stop being fixedly connected to the bottom end of the T-shaped slide rail, a locking block being slidably connected to the outer wall of the T-shaped slide rail, the outer wall of the locking block being slidably connected to the inner wall of the sliding groove, and the outer wall of the locking block being slidably connected to the inner wall of the locking groove.

[0007] As a further description of the above technical solution: The size segmentation mechanism also includes an unlocking lever, the bottom end of which is fixedly connected to the top end of the locking block, and the outer wall of the unlocking lever is slidably connected to the inner wall of the operating table.

[0008] As a further description of the above technical solution: The size segmentation mechanism also includes a spring baffle, the inner wall of which is slidably connected to the outer wall of the unlocking lever.

[0009] As a further description of the above technical solution: The size segmentation mechanism also includes a rebound spring, the top end of which is fixedly connected to the bottom end of the spring baffle, and the bottom end of which is fixedly connected to the top end of the locking block.

[0010] As a further description of the above technical solution: The size segmentation mechanism also includes a cutting blade, the top of which is fixedly connected to the bottom of the T-shaped slide rail, and the top of which is slidably connected to the bottom of the operating table.

[0011] As a further description of the above technical solution: The size segmentation mechanism also includes a pull ring, the outer wall of which is fixedly connected to the top of the unlocking lever.

[0012] As a further description of the above technical solution: The positioning auxiliary mechanism includes a positioning ruler, the outer wall of which is fixedly connected to the top of the operating table, and a cutting groove is provided on the top of the wiring table.

[0013] As a further description of the above technical solution: The positioning auxiliary mechanism also includes a drag-reducing wheel, the outer wall of which is rotatably connected to the inner wall of the bottom stop block, and the outer wall of which is slidably connected to the bottom end of the operating table.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the size segmentation mechanism can adjust the cutting blade distance in segments to achieve one-time cutting. Pulling down the pull ring drives the unlocking lever, compresses the spring spring to make the locking block disengage from the locking groove, moves the T-shaped slide rail along the slide groove, adjusts the cutting blade distance connected to the bottom stop block, and after releasing, the locking block locks back into the locking groove and is fixed. Different lengths of ribbon wire can be cut in one cut without repeatedly adjusting the cutting blade, saving operation time.

[0015] 2. In this utility model, the positioning auxiliary mechanism enhances the overall practicality of the device. The positioning scale at the top of the operating table facilitates accurate determination of the cutting blade spacing. The drag-reducing wheel of the bottom stop reduces moving friction, allowing the T-shaped slide rail to slide more smoothly. The cutting groove of the wiring table works in conjunction with the cutting blade to prevent the blade from damaging the table surface. Overall, the operation is more convenient and the cutting is more accurate. Attached Figure Description

[0022] Working principle: This LCD display production cable cutting and positioning device uses the cable tray 1 as the basic support platform. The size segmentation mechanism 2 realizes the segmented adjustment of the spacing of the cutting blades 221 and the one-time cutting of the cable. The positioning auxiliary mechanism 3 improves the size positioning accuracy and the smoothness of component movement. The two work together to solve the problems of traditional devices that require multiple adjustments and cutting, are cumbersome and time-consuming, and have poor accuracy. It is adapted to the high-efficiency and precise cutting requirements of LCD display cables and ensures the efficiency of mass production.

[0023] Before cutting the cable, the core process is completed through the size segmentation mechanism 2. The operator first pulls the ring 222 at the top of the unlocking lever 218 according to the required cable length. The ring 222 causes the unlocking lever 218 to slide along the inner wall of the operating table 212. Simultaneously, the locking block 217 fixed at the bottom of the unlocking lever 218 slides along the inner wall of the slide groove 214, compressing the return spring 219 between the top of the locking block 217 and the bottom of the spring baffle 220. The inner wall of the spring baffle 220 slides against the outer wall of the unlocking lever 218, providing spring support, until the locking block 217 disengages from the locking groove 213 on the inner wall of the operating table 212, releasing the T-shaped slide rail 215. Then, the T-shaped slide rail 215 moves along the slide groove 214, and the bottom stop block 216 fixed at the bottom of the T-shaped slide rail 215 moves synchronously, causing the cutting blade 221 at the bottom of the T-shaped slide rail 215 to adjust its position. Combined with the positioning scale 311 at the top of the operating table 212, the spacing of each cutting blade 221 is determined to adapt to the needs of different lengths of cabling. After the spacing is adjusted, the pull ring 222 is released, and the return spring 219 returns to its original position, pushing the locking block 217 to engage with the corresponding locking groove 213, fixing the T-shaped slide rail 215 and the cutting blade 221. A whole row of cabling is placed on the cabling table 1, and the cutting blade 221 is pressed down. The cutting blade 221 slides along the bottom of the operating table 212 and cuts into the cutting groove 312 at the top of the cabling table 1, completing the cutting of different lengths of cabling in one go without the need for repeated blade adjustments.

[0024] During adjustment and cutting, the positioning auxiliary mechanism 3 provides full support. The positioning scale 311 at the top of the operating table 212 has clear graduations, allowing operators to intuitively read and accurately adjust the spacing of the cutting blades 221, avoiding dimensional deviations caused by manual estimation. When the T-shaped slide rail 215 moves, the drag-reducing wheel 313, which is rotatably connected to the inner wall of the bottom stop 216, slides in contact with the bottom end of the operating table 212. The drag-reducing wheel 313 rolls synchronously with the movement of the bottom stop 216, greatly reducing the frictional resistance between the bottom stop 216 and the operating table 212, making the sliding of the T-shaped slide rail 215 smoother and less strenuous. The cutting groove 312 at the top of the wiring table 1 corresponds to the position of the cutting blade 221, providing space for the blade during cutting, preventing the blade from directly contacting the surface of the wiring table 1 and causing damage, extending the blade's lifespan, and ensuring a flat cut surface.
