[0002] The multi-point positioning system for high-precision cutting of precision structural adhesive tape is a device designed specifically for high-precision cutting operations. It is commonly used in industries such as electronics, automotive, and medical equipment, where there are extremely high requirements for the dimensional accuracy and cutting quality of the tape. In the production process of adhesive tape, it needs to be rolled into a cylindrical tube, and then the long cylindrical adhesive tape is placed on a cutting machine for rotation and cutting to obtain the required tape length. When cutting adhesive tape, the adhesive tape layer will be concave after the cutting blade comes into contact with the adhesive tape. This can easily cause the cut part of the adhesive tape to shift during cutting, making the adhesive tape unusable. Therefore, in order to solve the above problems, a multi-point positioning system and control method based on precision structure adhesive tape high-precision cutting is proposed.

[0012] A multi-point positioning system and control method based on high-precision cutting of precision structural adhesive tape. S1: When ensuring cutting accuracy of the adhesive tape body, the device is powered by an external power source during use. The adhesive tape body is fitted onto the outside of the folding rod, and is limited by bolts and baffles. The adhesive tape body can rotate outside the folding rod. The motor at one end of the cutting disc is started, causing the cutting disc to rotate. As the cutting disc rotates, it cuts the outside of the adhesive tape body. Under the friction between the cutting disc and the adhesive tape body, the cutting disc rotates and the adhesive tape body rotates accordingly. At the same time, the electric telescopic rod is activated, which pushes the blade holder and the cutting disc to move, thereby performing a full cut on the adhesive tape body. When the adhesive tape body rotates, the adhesive tape body is in contact with the outside of the auxiliary components, and the rubber nozzle disc is in contact with the outside of the adhesive tape body. Under the pressure of the adhesive tape body, the sliding column and narrow plate are pushed to move. The outer side of the sliding column slides on the inner side of the fixed plate. At the same time, the return spring deforms. When the rubber nozzle plate slides to one-fifth of the distance inside the movable built-in groove, the sealing ring on the outer side of the bottom of the rubber nozzle plate contacts the upper end of the fixed plate. At this time, the sealing ring is outside the vent. Negative pressure is generated inside the air intake channel. Gas flows from the vent and the inner cylinder. At the same time, the suction fan is started. The suction fan draws air from the air channel support block. The gas enters the vent from the air intake channel, enters the outer cylinder from the vent, enters the inner groove from the outer cylinder, enters the inner cylinder from the inner groove, and enters the limiting groove and the through channel from the inner cylinder. It is discharged by the suction fan. At this time, when cutting, the two rubber nozzle plates are in contact with the outside of the adhesive tape body. Between the two rubber nozzle plates, the cutting blade is used for cutting. S2: When adjusting the position of the adhesive tape body and the approximate position of the cutting disc according to the size of the adhesive tape body, start the first servo motor. The first servo motor drives the first threaded rod to rotate. The first threaded rod drives the outer spirally connected slide plate to move. The slide plate is slidably connected to the inside of the worktable. The slide plate drives the folding rod and the adhesive tape body to move. Start the second servo motor. The second threaded rod drives the T plate to move. The T plate drives the air passage support block and the left end T plate to move. The left end T plate is slidably connected to the outside of the limiting column. S3: When cleaning the colloid on the outside of the cutting disc, the cutting disc contacts the scraper when the cutting disc rotates. Under the elastic force of the spring extension rod, the scraper keeps in contact with the outside of the cutting disc and scrapes off the colloid on the outside of the cutting disc.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by incorporating an anti-dent component, an inner cylinder, an outer cylinder, a movable internal groove, and a suction fan, the device can adsorb the outer side of the adhesive tape body, preventing dents from occurring on the adhesive tape body during the cutting process and improving the cutting accuracy of the adhesive tape body. This ensures the pass rate of adhesive tape. In this invention, by setting a first servo motor, a second servo motor, a second threaded rod, a first threaded rod, a limiting column, a lifting and cutting assembly, and a turning rod, the device adjusts the distance of the cutting disc according to the size of the adhesive tape body, while ensuring that the segmented cutting position of the adhesive tape body is controlled. In this invention, by using a rear folding plate, spring telescopic rod, scraper and lifting cutting assembly, a certain amount of adhesive is adhered to the surface of the cutting disc as it cuts continuously. The device can continuously clean the adhesive on the surface of the cutting disc to prevent the adhesive on the surface of the cutting disc from affecting the cutting accuracy of the adhesive tape body. In this invention, the device, through the provided suction fan, air duct support block, through channel, limiting groove, inner cylinder and outer cylinder, can collect impurities generated during cutting by the anti-dent component, thereby preventing impurities from sticking to the outside of the adhesive tape body and preventing impurities from affecting the cutting accuracy of the adhesive tape body.

As a further implementation of this solution, there are two T-plates 31, which are fixedly connected to the left and right sides of the airway support block 32. The lower part of the electric telescopic rod 34 slides inside the airway support block 32. The upper part of the airway support block 32 is provided with two sliding hole scrapers 7. One side of the scraper 7 is attached to the outer side of the cutting disc 35. The scraper 7 corresponds one-to-one with the spring telescopic rod 6. The cutting disc 35 is installed between the two auxiliary components 4, which serves to continuously scrape off the colloid on the outside of the cutting disc 35 after cutting, so as to prevent the colloid from affecting the cutting accuracy of the cutting disc 35. As a further implementation of this solution, the upper inner side of the air channel support block 32 is provided with an opening, the through channel 37 is connected to the air inlet of the suction fan 33, the outer side of the inner cylinder 41 is rotatably connected to the inner side of the limiting groove 38, and the through channel 37 is connected to the inner side of the inner cylinder 41 through the limiting groove 38, so that the gas inside the auxiliary component 4 can be discharged through the suction fan 33, thereby facilitating the cleaning of impurities after cutting.

At the same time, it facilitates the gas exchange between the inner cylinder 41 and the outer cylinder 42, and facilitates the two rubber nozzle plates 441 to simultaneously adsorb the adhesive tape body 26, preventing the adhesive tape body 26 from being dented during cutting, and improving the cutting accuracy of the adhesive tape body 26.

[0020] The multi-point positioning system for high-precision cutting of precision adhesive tape of the present invention: When ensuring cutting accuracy of the adhesive tape body 26, the device is powered by an external power source during use. The adhesive tape body 26 is sleeved and installed on the outside of the folding rod 25. The adhesive tape body 26 is limited by bolts and baffles, allowing the adhesive tape body 26 to rotate outside the folding rod 25. The motor at one end of the cutting disc 35 is started, causing the cutting disc 35 to rotate. When the cutting disc 35 rotates, it cuts the outside of the adhesive tape body 26. Under the action of friction between the cutting disc 35 and the adhesive tape body 26, the cutting disc 35 rotates to cut the adhesive tape body 26. The tape body 26 rotates accordingly, simultaneously activating the electric telescopic rod 34. The electric telescopic rod 34 pushes the blade holder 36 and the cutting disc 35 to move, thereby performing a full cut on the adhesive tape body 26. As the adhesive tape body 26 rotates, it adheres to the outer side of the auxiliary component 4, and the rubber nozzle disc 441 adheres to the outer side of the adhesive tape body 26. Under the pressure of the adhesive tape body 26, the rubber nozzle disc 441 pushes the sliding column 443 and the narrow plate 447 to move. The outer side of the sliding column 443 slides inside the fixed disc 444, while the return spring 446 deforms, thus resetting the rubber nozzle disc 441. Figure 7 When the rubber nozzle plate 441 slides into the movable built-in groove 43, and the sealing ring on the bottom of the rubber nozzle plate 441 contacts the upper end of the fixed plate 444, the sealing ring is located outside the vent 445. A negative pressure is generated inside the suction channel 442, and gas flows from the vent 445 and the outer cylinder 42. At the same time, the suction fan 33 is activated, drawing air from the airway support block 32. The gas enters the vent 445 from the suction channel 442 and then enters the outer cylinder from the vent 445. 42. The outer cylinder 42 enters the inner through groove 45, the inner through groove 45 enters the inner cylinder 41, and from the inner cylinder 41 it enters the limiting groove 38 and the through channel 37, and is discharged by the suction fan 33. At this time, during cutting, the two rubber nozzle discs 441 contact the outside of the adhesive tape body 26. Between the two rubber nozzle discs 441, the cutting disc 35 cuts, thereby ensuring that the adhesive tape body 26 is not dented when cutting, and at the same time facilitating the discharge of impurities. When adjusting the position of the adhesive tape body 26 and the approximate position of the cutting disc 35 according to the size of the adhesive tape body 26, the first servo motor 22 is started. The first servo motor 22 drives the first threaded rod 23 to rotate. The first threaded rod 23 drives the outer spirally connected sliding plate 24 to move. The sliding plate 24 is slidably connected to the inner side of the worktable 21, which plays a limiting role. The sliding plate 24 drives the folding rod 25 and the adhesive tape body 26 to move. At this time, the position of the adhesive tape body 26 is controlled, and the cutting accuracy of the adhesive tape body 26 is improved. The second servo motor 27 is started, and the second threaded rod 28 drives the T plate 31 to move. The T plate 31 drives the air passage support block 32 and the left end T plate 31 to move. The left end T plate 31 is slidably connected to the outside of the limiting column 29, which plays a limiting role when the air passage support block 32 moves, thereby driving the cutting disc 35 to move closer to the adhesive tape body 26 and controlling the cutting accuracy of the adhesive tape body 26. When cleaning the colloid on the outside of the cutting disc 35, the cutting disc 35 contacts the scraper 7 when it rotates. Under the elastic force of the spring telescopic rod 6, the scraper 7 remains in contact with the outside of the cutting disc 35. The scraper 7 scrapes off the colloid on the outside of the cutting disc 35, thereby preventing the colloid from affecting the cutting accuracy of the cutting disc 35.
