Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to an adhesive-backed laser cutting device. Background Technology

[0002] Adhesive-backed materials (such as pressure-sensitive tape, double-sided tape, foam adhesive, and thermally conductive films) are widely used in electronic components, automotive interiors, medical devices, and flexible circuit boards. As electronic products become thinner, smaller, and more integrated, higher demands are placed on the cutting precision and edge quality of adhesive-backed products. Laser cutting, with its advantages of being non-contact, having no tool wear, high cutting precision, and producing burr-free edges, is gradually replacing traditional die-cutting processes and becoming the mainstream method for precision processing of adhesive-backed materials.

[0003] In the process of laser cutting adhesive-backed materials, ensuring the stable and flat fixation of the adhesive strip to be cut is crucial to guaranteeing cutting accuracy. Existing laser cutting devices typically use a vacuum adsorption platform to directly adsorb the adhesive strip. However, this platform is usually a rigid porous plate made of metal or ceramic. During cutting, the laser may burn the surface of the adsorption platform after penetrating the adhesive layer. Simultaneously, the charred residue and fumes generated from the melting adhesive can easily clog the micropores, leading to uneven adsorption force distribution and requiring frequent shutdowns for cleaning, severely impacting production efficiency. To address this technical problem, a new laser cutting device for adhesive-backed materials is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an adhesive-backed laser cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A laser cutting device for adhesive backing includes: a frame; A laser cutting component mounted on the frame, the laser cutting component including a moving platform and a laser cutter, the moving platform being mounted on the frame, the laser cutter being mounted on the output end of the moving platform, the moving platform being used to drive the laser cutter to move; An adsorption stage is elastically mounted on the frame and located below the laser cutting component. The surface of the adsorption stage is arrayed with several negative pressure holes for providing negative pressure. An annular protective sleeve is fitted over the outside of the adsorption stage, and the annular protective sleeve is attached to the adsorption stage near the top area of ​​the adsorption stage; the annular protective sleeve includes a flexible middle sleeve, edge auxiliary adsorption sleeves provided on both sides of the flexible middle sleeve, and a rotating assembly that drives its rotation, and the edge auxiliary adsorption sleeves have a micro-permeable structure. An automatic cleaning component installed on the drive frame is used to clean the surface of the annular protective sleeve away from the adsorption table. And a winding component mounted on the frame for unwinding the adhesive tape.

[0006] As a further embodiment of the present invention: the edge-assisted adsorption sleeve includes, from top to bottom, a surface layer, a flexible elastic layer and a bottom layer, both of which are provided with microporous structures, and the flexible elastic layer is made of open-cell flexible foam.

[0007] As a further embodiment of the present invention, it also includes no fewer than four guide rollers that support the annular protective sleeve. The no fewer than four guide rollers are evenly distributed along the lower part of the adsorption platform, and one of the guide rollers is provided with a drive motor that drives its rotation. The drive motor is connected to the guide roller in a transmission manner.

[0008] As a further embodiment of the present invention: the winding component includes an unwinding roller and a winding roller mounted on a frame, with the unwinding roller and the winding roller distributed at both ends of the frame.

[0009] As a further embodiment of the present invention: the automatic cleaning component includes a cleaning lifting roller and a cleaning rod rotatably mounted on a mounting base. The mounting base is fixedly mounted on a frame. The cleaning lifting roller is used to lift the annular protective sleeve downwards. The cleaning rod has a plurality of air nozzles arranged in an array along the width direction of the annular protective sleeve. The air nozzles are located below the annular protective sleeve and are connected to a high-pressure cleaning air source. The cleaning lifting rollers are positioned towards the top of the annular protective sleeve, and their nozzles are in the opposite direction to the movement of the annular protective sleeve.

[0010] As a further embodiment of the present invention: a swing mechanism is provided between the cleaning lifting roller and the cleaning rod to drive the cleaning rod to swing along the width direction of the annular protective sleeve.

[0011] As a further embodiment of the present invention: the swing mechanism includes gear A, gear B, transmission disk and mating disk. Gear A is coaxially arranged with the cleaning lifting roller and meshes with gear B. Gear B is rotatably mounted on the mounting base and coaxially fixedly connected to the transmission disk. The mating disk is rotatably sleeved on the transmission disk and can elastically slide along the axial direction of the transmission disk. A driving assembly for driving the mating disk to swing left and right is provided between the transmission disk and the mating disk. The cleaning rod is mounted on the driving assembly.

[0012] As a further embodiment of the present invention: the driving component includes an even number of abutment rods arranged in an array on the inner wall of the mating disc, and an even number of arc-shaped protrusions arranged in a circumferential array near the end of the abutment rod of the transmission disc, the arc-shaped protrusions being arranged on the trajectory of the abutment rod, and a fixing rod being provided at the end of the mating disc, the cleaning rod being connected to the fixing rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: During use, the adhesive to be cut needs to pass through the top of the adsorption table and be attached to the annular protective sleeve. The adsorption table provides negative pressure to the annular protective sleeve, so that the annular protective sleeve and the adhesive tape are tightly adsorbed on its surface, ensuring that the tape position is stable and without displacement during the cutting process; then the winding component, the annular protective sleeve and the laser cutting component are powered on simultaneously to perform cutting. During the cutting process, the adhesive tape is always adsorbed on the surface of the annular protective sleeve, thereby effectively avoiding cutting deviations caused by tape slippage or lifting. Since the annular protective sleeve has a ring structure and an automatic cleaning component is set to clean the surface of the annular protective sleeve, it can be ensured that the annular protective sleeve can be reused, avoiding downtime.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1 to 11The present invention provides a structural diagram of an adhesive laser cutting device according to Embodiment 1. The adhesive laser cutting device includes: a frame 10, a laser cutting component 20, an adsorption table 30, an annular protective sleeve 40, an automatic cleaning component 50, and a winding component 60. The laser cutting component 20 is mounted on the frame 10. The laser cutting component 20 includes a moving platform 201 and a laser cutter 202. The moving platform 201 is mounted on the frame 10, and the laser cutter 202 is mounted on the output end of the moving platform 201. The moving platform 201 is used to drive the laser cutter 202 to move. The adsorption platform 30 is elastically mounted on the frame 10 and located below the laser cutting component 20. The surface of the adsorption platform 30 is arrayed with several negative pressure holes 301 for providing negative pressure. The annular protective sleeve 40 is fitted over the outside of the adsorption platform 30, with the area near the top of the adsorption platform 30 affixed to it. The annular protective sleeve 40 includes a flexible intermediate sleeve 401, edge auxiliary adsorption sleeves 402 disposed on both sides of the flexible intermediate sleeve 401, and a rotating assembly for driving its rotation. The edge auxiliary adsorption sleeves 402 have a micro-permeable structure. The automatic cleaning component 50 is mounted on the frame 10 and is used to clean the surface of the annular protective sleeve 40 away from the adsorption platform 30. The winding component 60 is mounted on the frame 10 and is used to unwind the adhesive tape. The flexible intermediate sleeve 401 is made of high-temperature resistant material and is located in the cutting area to prevent damage during the cutting process. The edge auxiliary adsorption sleeves 402 have a micro-permeable structure to allow the adhesive tape to be processed to be adsorbed onto its surface, thereby achieving stable adsorption and precise positioning. The flexible intermediate sleeve 401 can be made of high-temperature resistant silicone, polyimide or ceramic-coated composite material.

[0031] In this invention, the adhesive tape to be cut passes over the adsorption platform 30 and is placed on the annular protective sleeve 40. The adsorption platform 30 provides negative pressure to the annular protective sleeve 40, so that the annular protective sleeve 40 and the adhesive tape are tightly adsorbed on its surface, ensuring that the tape position is stable and without displacement during the cutting process. Then, the winding component 60, the annular protective sleeve 40 and the laser cutting component 20 are simultaneously powered on to perform cutting. During the cutting process, the adhesive tape is always adsorbed on the surface of the annular protective sleeve 40, thereby effectively avoiding cutting deviations caused by tape slippage or lifting. Since the annular protective sleeve 40 has a ring-shaped structure and the surface of the annular protective sleeve 40 is cleaned by the automatic cleaning component 50, the annular protective sleeve 40 can be reused.

[0032] like Figure 4As shown, in some embodiments, the adsorption platform 30 is externally connected to a negative pressure source, which uniformly transmits negative pressure to the surface of the annular protective sleeve 40 through the negative pressure hole 301, thereby forming a stable adsorption force in the micro-permeable structure area of ​​the edge auxiliary adsorption sleeve 402; the negative pressure source is a vacuum pump or a negative pressure generator, and its air extraction port is connected to the internal cavity of the adsorption platform 30 through a pipeline. Several elastic telescopic rods 302 are provided at the bottom of the adsorption platform 30, and these elastic telescopic rods 302 are evenly arranged at the bottom of the elastic adsorption platform 30 and fixedly installed on the frame 10.

[0033] like Figure 5 As shown, in some embodiments, the edge-assisted adsorption sleeve 402 includes, from top to bottom, a surface layer 404, a flexible elastic layer 405, and a bottom layer 406. Both the surface layer 404 and the bottom layer 406 have microporous structures. The flexible elastic layer 405 serves as an intermediate transition layer and is made of open-cell flexible foam. The flexible elastic layer 405 has compression resilience, allowing it to be compressed into a flat plate structure under negative pressure. The bottom layer 406 can be a microporous release membrane (such as a breathable PE membrane with a microporous structure) or non-woven release paper, and the surface layer 404 can be a porous PTFE membrane (such as Gore-Tex materials) or an electrospun nanofiber membrane.

[0034] In some embodiments, the surface layer 404 is a wear-resistant layer used to contact the adhesive tape and withstand the reciprocating friction of the cutting tool; the bottom layer 406 is a highly breathable base layer used to directly contact the upper surface of the adsorption platform 30 to ensure that the negative pressure is efficiently conducted to the surface of the surface layer 404, thereby achieving uniform and stable adsorption of the adhesive tape; the micropore diameter of the bottom layer 406 is larger than that of the surface layer 404, so as to ensure the negative pressure conduction efficiency while avoiding micropore blockage and extending the overall service life of the edge auxiliary adsorption sleeve 402.

[0035] like Figure 1 As shown, in some embodiments, the present invention further includes no fewer than four guide rollers 403 supporting the annular protective sleeve 40. These guide rollers 403 are evenly distributed along the underside of the adsorption platform 30, and one of the guide rollers 403 is equipped with a drive motor that drives its rotation. The drive motor is connected to the guide roller 403 to provide power to the annular protective sleeve 40, enabling it to rotate synchronously with the adhesive strip, ensuring constant tension and smooth tape feeding during the cutting process. The annular movement direction of the annular protective sleeve 40 is consistent with the conveying direction of the adhesive strip, thereby achieving continuous and synchronous movement of the adhesive strip on the annular adsorption surface of the annular protective sleeve 40, thus ensuring no relative slippage of the adhesive strip throughout the cutting process. The guide rollers 403 are rotatably mounted on the frame 10.

[0036] like Figure 1As shown, in some embodiments, the winding component 60 includes an unwinding roller 601 and a winding roller 602 mounted on the frame 10. The unwinding roller 601 and the winding roller 602 are used to cooperate in unwinding and winding the adhesive backing. The unwinding roller 601 and the winding roller 602 are distributed at both ends of the frame 10. The unwinding roller 601 is used to carry the adhesive backing strip roll to be cut and to achieve constant tension unwinding; the unwinding roller 601 is used to wind the cut adhesive backing strip into a roll and cooperates with the winding roller 602 to achieve continuous unwinding-cutting-winding operation.

[0037] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the automatic cleaning component 50 includes a cleaning lifting roller 501 and a cleaning rod 506 rotatably mounted on a mounting base 510. The mounting base 510 is fixedly mounted on the frame 10. The cleaning lifting roller 501 is used to lift the annular protective sleeve 40 downwards. A plurality of air nozzles 507 are arranged in an array on the cleaning rod 506, along the width direction of the annular protective sleeve 40. The air nozzles 507 are located below the annular protective sleeve 40 and are connected to a high-pressure cleaning air source. The air nozzles 507 face the top of the cleaning lifting roller 501 on the annular protective sleeve 40, and their nozzles face the opposite direction of travel of the annular protective sleeve 40. The air nozzles 507 blow and clean the surface of the annular protective sleeve 40 at the lifted position to remove residual adhesive residue and dust. The lifting arrangement facilitates cleaning of the surface of the annular protective sleeve 40, allowing residual adhesive residue to be efficiently blown away from the adsorption surface, thus ensuring the quality of secondary cutting.

[0038] In some embodiments, to further improve the cleaning quality of the air nozzle 507, a swing mechanism is also provided between the cleaning lifting roller 501 and the cleaning rod 506 to drive the cleaning rod 506 to swing along the width direction of the annular protective sleeve 40. This enables high-pressure blowing from multiple angles, improving the cleaning effect.

[0039] like Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the swing mechanism includes gear A502, gear B503, transmission disk 504, and mating disk 505. Gear A502 is coaxially arranged with the cleaning lifting roller 501, and gear A502 meshes with gear B503. Gear B503 is rotatably mounted on the mounting base 510. Gear B503 is coaxially fixedly connected with the transmission disk 504. The mating disk 505 is rotatably sleeved on the transmission disk 504 and can elastically slide along the axial direction of the transmission disk 504. A drive assembly for driving the mating disk 505 to swing left and right is provided between the transmission disk 504 and the mating disk 505. The cleaning rod 506 is mounted on the drive assembly.

[0040] like Figure 8 As shown, in some embodiments, the driving assembly includes an even number of abutment rods 512 arrayed on the inner wall of the mating disc 505. An even number of arc-shaped protrusions 513 are arrayed circumferentially near the ends of the abutment rods 512 on the transmission disc 504. The arc-shaped protrusions 513 are positioned along the tracks of the abutment rods 512. A fixing rod 517 is also provided at the end of the mating disc 505, and the cleaning rod 506 is connected to the fixing rod 517. Thus, when the transmission disc 504 rotates under the drive of the gear B503, the abutment rods 512 intermittently pass over the arc-shaped protrusions 513, thereby driving them to reciprocate along the axial direction of the transmission disc 504.

[0041] In some embodiments of the present invention, a mounting ring 511 is rotatably sleeved on the outer side of the transmission disk 504, and an elastic element 514 is connected to the mounting ring 511. The end of the elastic element 514 away from the mounting ring 511 is fixedly installed on the inner wall of the mating disk 505, so that the mating disk 505 can slide elastically along the axial direction of the transmission disk 504.

[0042] like Figure 8 As shown in some embodiments of the present invention, in order to guide the sliding of the mating disc 505, a slider 515 is fixedly installed on the top of the mating disc 505. The slider 515 is slidably disposed in the strip-shaped groove at the bottom of the guide block 516 along the axial direction of the transmission disc 504, and the guide block 516 is fixedly installed on the mounting base 510. The guide block 516 and the mounting base 510 are integrally formed or fastened together by bolts, thus guiding and limiting the left and right elastic sliding of the mating disc 505, ensuring stable swing trajectory and high repeatability. A wear-resistant bushing is provided between the slider 515 and the groove of the guide block 516 to reduce sliding friction resistance and extend the service life of the mechanism.

[0043] In some embodiments of the present invention, the abutting rod 512 abuts against a universal ball provided at the end of the arc-shaped protrusion 513, and the universal ball and the end face of the arc-shaped protrusion 513 are in point contact to provide resistance-free steering support during the reciprocating swing of the drive mating disc 505.

[0044] like Figure 7 , Figure 9 and Figure 10 As shown, in order to further improve cleaning efficiency and adaptability, the present invention also includes a swaying mechanism that drives the cleaning rod 506 to swing during left and right sliding, so as to further increase the tilt range and improve the cleaning effect.

[0045] In some embodiments of the present invention, the shaking mechanism includes a drive rod 509 and a wedge block 508. The cleaning rod 506 is elastically rotatably mounted on the fixed rod 517 near the fixed rod 517 via a mounting shaft 525. One end of the mounting shaft 525 is fixedly mounted on the cleaning rod 506, and the other end of the mounting shaft 525 is rotatably mounted in a mounting groove on the fixed rod 517. A torsion spring is sleeved on the outside of the mounting shaft 525, and the two ends of the torsion spring are respectively fixedly mounted on the mounting shaft 525 and the side wall of the mounting groove. In this way, the cleaning rod 506 is rotatably mounted on the fixed rod 517. The drive rod 509 is fixedly installed on the mounting base 510 near the cleaning rod 506, and the inclined block 508 is fixedly installed on the lower side of the cleaning rod 506. The end of the drive rod 509 abuts against the inclined surface of the inclined block 508. Thus, when the cleaning rod 506 slides along the width of the annular protective sleeve 40, the action of the drive rod 509 and the inclined block 508 causes the cleaning rod 506 to periodically swing around the axis of the mounting shaft 525, thereby driving the air nozzle 507 to swing, thereby expanding the coverage angle and dynamic cleaning trajectory of the air nozzle 507 on the target surface, effectively improving the cleaning effect.

[0046] In some embodiments of the present invention, the automatic cleaning component 50 further includes an electrostatic dust removal component located downstream of the air nozzle 507, for secondary adsorption and collection of fine dust remaining after mechanical cleaning by 507.

[0047] like Figure 11 As shown in some embodiments of the present invention, the electrostatic dust removal assembly includes a housing 519, an electrostatic generator 520, a dust collecting electrode 518, and a plurality of ion rods 521. The electrostatic generator 520, the dust collecting electrode 518, and the plurality of ion rods 521 are installed inside the housing 519. The electrostatic generator 520 is connected to the plurality of ion rods 521 and provides high-voltage direct current to the ion rods 521, causing the plurality of ion rods 521 to generate a strong electrostatic field. The dust collecting electrode 518 is located downstream of the ion rods 521. The dust collecting electrode 518 is a dust collecting plate, the surface of which is coated with a conductive coating and grounded, for capturing and neutralizing charged dust particles in the electrostatic field generated by the ion rods 521.

[0048] In some embodiments of the present invention, since the surface of the ion rod 521 is prone to dust accumulation after a period of use, affecting its discharge effect, the present invention also includes a cleaning component for cleaning the surface of several ion rods 521 in order to solve this technical problem. The cleaning component includes a mounting frame 523 that is lifted and lowered in the housing 519. Several cleaning rings 522 are fixedly installed on the mounting frame 523. The cleaning rings 522 are correspondingly arranged with several ion rods 521, and the cleaning rings 522 are sleeved on the ion rods 521. Flexible scrapers for scraping and cleaning the surface of the ion rods 521 are arranged on the inner wall of the cleaning rings 522.

[0049] In order to drive the mounting frame 523 to move up and down, the bottom of the mounting frame 523 is fixedly installed on the protruding end of the lifting component 524. The lifting component 524 is fixedly installed on the inner wall of the housing 519, and the lifting component 524 is an electric push rod or a pneumatic telescopic cylinder.

[0050] The working principle of this invention is: In use, the adhesive strip to be cut needs to pass over the adsorption table 30 and be placed on the annular protective sleeve 40. The adsorption table 30 provides negative pressure to the annular protective sleeve 40, so that the annular protective sleeve 40 and the adhesive strip are tightly adsorbed on its surface, ensuring that the strip is stable and does not shift during the cutting process. Then, the winding component 60, the annular protective sleeve 40, and the laser cutting component 20 are simultaneously powered on to perform cutting. During the cutting process, the adhesive strip is always adsorbed on the surface of the annular protective sleeve 40. During the cutting process, the guide roller 403 guides it to ensure that the adhesive strip is smoothly conveyed along the preset path. During the rotation of the annular protective sleeve 40, the cleaning lifting roller 501 is driven to rotate. 1. The cleaning rod 506 is driven to reciprocate along the width of the annular protective sleeve 40 by gears A502, B503, transmission disc 504, and mating disc 505. The air nozzle 507 on the cleaning rod 506 swings to dynamically clean the surface of the annular protective sleeve 40. At the same time, the drive rod 509 and the inclined block 508 work together to make the cleaning rod 506 swing periodically around the mounting shaft 525, thereby further enhancing the multi-angle, non-repetitive cleaning coverage of the surface of the annular protective sleeve 40 by 507, effectively avoiding cleaning blind spots, significantly improving the cleanliness of the surface of the annular protective sleeve 40 and the subsequent adhesive bonding quality. After cleaning, the electrostatic dust removal component performs further secondary dust removal to ensure the dust removal effect.
