Therefore, they should not be construed as limitations on this utility model.

[0029] like Figure 1-4As shown, a multi-layer fabric precision alignment and cutting device includes: a support frame 1; a positioning platform 2 and a connecting platform 3 fixed above the support frame 1. The positioning platform 2 and the connecting platform 3 can be made of flat metal plates (such as stainless steel plates) with polished surfaces to reduce friction between the fabric and the platform. Space needs to be reserved inside the positioning platform 2 for installing a vacuum adsorption limiting component 6; a controller 4 and a drive component 5 controlled by the controller 4. A distance measuring instrument 10, a bidirectional motor, the vacuum adsorption limiting component 6, and an electromagnetic pressure plate 9 are all electrically connected to the controller 4. The controller 4 can be a PLC (Programmable Logic Controller) or a microcontroller. The bidirectional motor can be controlled by programming, including forward and reverse rotation, speed adjustment, and other functions. The later maintenance of the drive component 5, such as adding lubricating oil, will not affect the structural integrity of this technical solution, therefore its maintenance will not be described in detail. The connecting plate 8, which drives the horizontal movement of the drive component 5, has two parallel electromagnetic pressure plates 9 and a vertically arranged laser alignment light 11 at its bottom. The laser alignment light 11 emits a visible red laser for easy observation. The laser spot emitted by the laser alignment light 11 can be projected onto the fabric. The operator can adjust the fabric according to the position of the spot to align it with the length direction of the electromagnetic pressure plate 9. The laser alignment light 11 can be fixed by a support frame or bolts. The positioning platform 2 also includes a vacuum adsorption limiting component 6 inside and an iron-containing limiting plate 7 at the top. The limiting plate 7 can be made of iron-containing material. The steel used is of high quality and galvanized to prevent rust and improve its magnetic attraction with the electromagnetic pressure plate 9. When the electromagnetic pressure plate 9 is energized, it can only move up and down due to the limiting action of the telescopic rod 901. Under the magnetic attraction, the fabric can be clamped between the electromagnetic pressure plate 9 and the limiting plate 7, thus limiting its movement and ensuring that the fabric will not shift during the cutting process. The distance measuring instrument 10 is used to detect the displacement of the connecting plate 8 in real time and feed it back to the controller 4 to achieve closed-loop control. The distance measuring instrument 10 is set on one of the slide rails 501. The length of the positioning platform 2 and the distance measuring instrument are known. The distance between the measuring instrument 10 and the laser alignment light 11 can be used to calculate the length from the laser alignment light 11 to the cutting gap, thereby achieving precise cutting. The measuring instrument 10 measures that the optical path or signal line is perpendicular to the moving direction of the connecting plate 8 to ensure measurement accuracy. The measuring instrument 10 is connected to the controller 4 through a data transmission line and transmits the detected displacement data to the controller 4 in real time. The controller 4 adjusts the speed and direction of the bidirectional motor according to the feedback data to achieve precise movement of the connecting plate 8. The measuring instrument 10 is existing technology, and the model can be selected according to the actual cutting accuracy. It will not be described in detail here.

[0030] like Figure 4As shown, the electromagnetic pressure plate 9 is elastically connected to the connecting plate 8 via a telescopic rod 901 and a spring 902. When energized, it generates magnetic force to press down and magnetically fix the edge of the fabric to the limiting plate 7. Specifically, the telescopic rod 901 can be made of high-strength aluminum alloy to ensure its stability and durability in long-term use; the spring 902 can be made of stainless steel with a high elastic coefficient to ensure that it can maintain good elastic performance after multiple extensions and retractions. When the electromagnetic pressure plate 9 is energized and generates magnetic force, the telescopic rod 901 and the spring 902 extend to achieve stable pressing and fixing of the edge of the fabric by the electromagnetic pressure plate 9. When it is de-energized, under the action of the elastic potential energy of the spring 902, the electromagnetic pressure plate 9 rises and cancels the limiting of the edge of the fabric.

[0031] like Figure 3 As shown, the driving component 5 includes two sets of parallel slide rails 501, a slider 502 slidably disposed in the slide rails 501, a lead screw 503 rotatably disposed in the slide rails 501, and a bidirectional motor that drives the two lead screws 503 to rotate synchronously. The connecting plate 8 is fixed to the top of the slider 502, and the slider 502 is threaded onto the lead screw 503. Specifically, the bidirectional motor can drive the two lead screws 503 to rotate synchronously, thereby driving the two sliders 502 to slide synchronously on the slide rails 501.

[0032] like Figure 3 As shown, the lead screw 503 is linked to the bidirectional motor through a worm gear mechanism. The end of the lead screw 503 is connected to the worm gear, and the two ends of the output shaft of the bidirectional motor are provided with worms that mesh with the worm gear. Specifically, the bidirectional motor drives the two worms to rotate synchronously. The worms mesh with the worm gear, thus driving the two lead screws 503 to rotate synchronously.

[0033] like Figure 2 As shown, the vacuum adsorption limiting component 6 includes a vacuum generator 601 and a vacuum suction cup 602. The surface height of the vacuum suction cup 602 is flush with the limiting plate 7 and is used to adsorb and fix the lower layer of fabric. Specifically, the top of the vacuum suction cup 602 has dense through holes to achieve vacuum adsorption of the fabric. The through holes are small in diameter and dense, thus avoiding fabric deformation caused by stress distribution.

[0034] like Figure 1-3 As shown, a cutting gap is provided between the positioning platform 2 and the connecting platform 3. The optical axis of the laser alignment light 11 is perpendicular to the length direction of the electromagnetic pressure plate 9. The laser alignment light 11 is set at a position away from the cutting gap. Specifically, the cutting gap can be designed as a rectangle to facilitate the passage of the cutting blade. The spacing of the cutting gap can be adjusted according to the actual cutting requirements, which is not limited here. The connecting platform 3 can also be equipped with a vacuum adsorption limiting component 6, a limiting plate 7, and an electromagnetic pressure plate 9 to limit the fabric, or a hand-held method can be used to limit the fabric to ensure cutting stability.

[0035] In summary: First, the fabric is placed on the positioning platform 2. Based on the cutting length, the data of the distance measuring instrument 10 is adjusted. Then, the speed and direction of the bidirectional motor are adjusted to drive the lead screw 503 to rotate synchronously through the worm gear mechanism, causing the slider 502 to slide within the slide rail 501. This allows the connecting plate 8 to move horizontally to the corresponding position. Afterward, the operator adjusts the position of the fabric according to the laser spot emitted by the laser alignment light 11, aligning it with the length direction of the electromagnetic pressure plate 9. Next, the vacuum adsorption limiting component 6 (including the vacuum generator 601 and the vacuum suction cup 602) in the positioning platform 2 is used to adsorb and fix the lower layer of fabric. After stacking multiple layers of fabric, the electromagnetic pressure plate 9 is energized to generate magnetic force. Under the extension of the telescopic rod 901 and the spring 902, it presses down and magnetically fixes the edge of the fabric with the limiting plate 7, achieving precise positioning of the fabric. Finally, precise cutting of the fabric can be achieved at the cutting gap.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
