Description

Technical Field

[0001] The utility model relates to the technical field of flexible screen cutting equipment, in particular to an automated cutting device for flexible screen production. Background Art

[0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly, reaching the boiling point of the material in a very short time, and the material begins to vaporize and form steam. The steam is ejected at a very high speed, and while the steam is ejected, a cut is formed on the material. In the prior art, when laser cutting a flexible screen, a large amount of odorous gas is generated floating in the surrounding environment, and the steam generated by the vaporization of the material lacks absorption and filtration, causing the staff to inhale harmful gases for a long time, and the filter components are not easy to replace.

[0003] For example, the authorized patent document with application number 2021209246816 discloses a LED flexible display screen laser cutting device, which realizes bidirectional synchronous cutting of the flexible display screen main body, shortens the cutting time, and improves the subsequent production efficiency of the flexible display screen main body; it includes a base, two sets of fixed plates, two sets of support plates, a motor, a first bevel gear, two sets of second bevel gears, two sets of cylindrical blocks, two sets of rotating shafts, two sets of gears, two sets of racks, two sets of moving blocks, two sets of T-shaped sliders, two sets of laser cutters, two sets of laser cutting heads, a cutting platform, a fixing assembly and a flexible display screen main body, the two sets of fixed plates are symmetrically fixed on the left and right sides of the top of the base, the two sets of support plates are fixed between the two sets of fixed plates, and are respectively located on the upper and lower sides of the two sets of fixed plates, and a slide groove is provided on the rear half of the bottom end of the upper support plate, and a slide groove is provided on the front half of the top end of the lower support plate, and the motor is fixed at the middle of the right end of the left fixed plate.

[0004] The above patent has the problem that when using laser to cut flexible screens, a large amount of odorous gas is generated floating in the surrounding environment, and the vapor generated by the material vaporization lacks absorption and filtration, so we need to provide an automated cutting device for flexible screen production. Utility Model Content

[0005] The utility model aims to provide an automated cutting device for the production of flexible screens. The flexible screen is placed on an operating table and fixed by a holding mechanism.

At the same time, the driving member is cooperated to realize the free adjustment of the horizontal direction of the laser cutter. The laser cutter generates smoke when working. The centrifugal fan is started to draw the air from the head of the laser cutter through the gas collecting hood and the air pipe, and then the air is sucked into the filter cartridge in the installation cylinder. Since the filter cartridge contains activated carbon adsorption particles, the smoke is purified. When the filter cartridge is replaced after long-term use, it is only necessary to rotate the filter cartridge so that the blocks on both sides of the filter cartridge rotate in the installation ring body until the blocks are ejected from the slot and the floating ring, thereby taking out the filter cartridge. When installing the filter cartridge, the blocks on the surface of the installation cartridge are inserted into the slot and pressed down. The blocks move the floating ring to compress the support spring, and the installation cartridge is rotated. The blocks on the surface of the installation cartridge are clamped in the limiting ring body to avoid the generation of a large amount of odorous gas floating in the surrounding environment, which causes the staff to inhale harmful gas for a long time, thereby solving the problems raised in the above-mentioned background technology.

[0031] A holding mechanism 8 disposed inside the operating table 1 for fixing the flexible screen;

[0032] The filter assembly 7 includes a centrifugal fan 71, an air pipe 72, an air collecting hood 73, a mounting cylinder 74, a limiter 70, a filter cylinder 75 and a clamping block 76. The top of the sliding seat 4 is provided with a mounting cylinder 74 through the centrifugal fan 71, and an air collecting hood 73 is installed on one side of the centrifugal fan 71 through the air pipe 72, and the air collecting hood 73 is arranged on one side of the laser cutter 6.

Two clamping grooves 704 are provided on the top of the mounting ring body 701, and the clamping block 76 on the surface of the filter cylinder 75 is adapted to the clamping groove 704.

[0034] In this embodiment, the flexible screen is placed on the operating table 1, and the flexible screen is fixed by a holding mechanism 8. The two cylinders 2 are synchronous cylinders 2. The cylinder 2 is started to drive the laser cutter 6 on the push plate 3 to move, and the driving member 5 is cooperated to realize the free adjustment of the horizontal direction of the laser cutter 6.

Since the filter cylinder 75 contains activated carbon adsorption particles, the smoke is absorbed by the filter cylinder 75. The air is purified. When the filter cartridge 75 is replaced after long-term use, it is only necessary to rotate the filter cartridge 75 so that the blocks 76 on both sides of the filter cartridge 75 rotate in the mounting ring body 701 until the blocks 76 are ejected from the slots 704 and the floating ring 703, thereby taking out the filter cartridge 75. When installing the filter cartridge 75, the blocks 76 on the surface of the mounting cylinder 74 are inserted into the slots 704 and pressed down, and the blocks 76 move the floating ring 703 to compress the support spring 702, and the mounting cylinder 74 is rotated, and the blocks 76 on the surface of the mounting cylinder 74 are clamped in the limiting ring body.

The pressing plate 85 is mounted on the top of the moving plate 83 through two electric push rods 84. The second motor 82 is mounted on one end of the double-threaded rod 81.

[0040] It should be noted that, by starting the second motor 82 to drive the double-threaded rod 81 to rotate, the two movable plates 83 move closer to or farther away from each other, and the appropriate spacing is adjusted according to the flexible screen.

[0044] The device places the flexible screen on the operating table 1, and fixes the flexible screen with the holding mechanism 8, starts the cylinder 2 to drive the laser cutter 6 on the push plate 3 to move, and cooperates with the driving member 5 to realize the free adjustment of the horizontal direction of the laser cutter 6. The laser cutter 6 generates smoke when it works, and starts the centrifugal fan 71 to suck the air from the head of the laser cutter 6 through the air collecting hood 73 and the air pipe 72, and inhales it into the filter cylinder 75 in the installation cylinder 74. Since the filter cylinder 75 contains activated carbon adsorption particles, the smoke is purified for a long time. When replacing the filter cartridge 75, it is only necessary to rotate the filter cartridge 75 so that the blocks 76 on both sides of the filter cartridge 75 rotate in the mounting ring body 701 until the blocks 76 are ejected from the slots 704 and the floating ring 703, thereby taking out the filter cartridge 75.
