Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a laser cutting device for insulating sheets. Background Technology
[0002] Insulating sheets are sheet-like insulating products made of materials such as polycarbonate (PC), polyester (PET), and polypropylene (PP). They are mainly used in the electronics and electrical industry for circuit insulation protection, physical separation, and thermal barrier construction. Due to their high-temperature resistance, flame retardancy, and chemical corrosion resistance, they are suitable for power supply equipment, displays, battery components, and other applications. They can be die-cut into different shapes to match diverse applications. In the production process of insulating sheets, laser cutting is used to cut the insulating sheets into pre-defined shapes. A light guide system composed of lenses and mirrors focuses the laser beam, forming a high-energy-density spot on the material surface. This instantly melts, vaporizes, or brings the material in the irradiated area to its ignition point. Simultaneously, auxiliary gases (such as compressed air or nitrogen) blow away the molten residue, thus achieving the cutting process. The laser beam is controlled by a CNC system and can move precisely along any pre-defined graphic path. Existing laser cutting equipment typically includes a laser system, a motion system, a positioning and fixing system, a control system, and auxiliary systems (such as cooling and dust extraction systems).
[0003] However, the positioning and fixing structures in existing laser cutting equipment are not well-suited for irregularly shaped special insulating sheets, resulting in insufficient positioning accuracy and consequently reduced cutting accuracy. Utility Model Content
[0004] Therefore, it is necessary to provide a laser cutting device for insulating sheets to address the technical problem that the positioning structure of existing laser cutting equipment is not adaptable to irregularly shaped insulating sheets.
[0005] An insulating sheet laser cutting device includes a housing, a positioning mechanism, and a cutting mechanism. Both the positioning mechanism and the cutting mechanism are installed in the housing. The positioning mechanism is arranged along a preset flat plane of the insulating sheet, and the cutting mechanism is located on the top side of the positioning mechanism.
[0006] The positioning mechanism includes a positioning plate and a suction structure; the housing is provided with a working cavity, and the positioning plate is located at the bottom of the working cavity; the suction structure is located on the bottom side of the working cavity, and one end of the suction structure is connected to the bottom surface of the positioning plate, and the other end of the suction structure extends to the outside of the housing; based on this, the surface of the positioning plate is provided with an array of through holes, and the array of through holes is connected from the top side of the positioning plate to the suction structure on the bottom side of the positioning plate.
[0007] The positioning plate is provided with several limiting modules, which are arranged in an array on the top side surface of the positioning plate. Based on this, each limiting module is provided with several secondary through holes corresponding to the through hole array. The secondary through holes are arranged through each limiting module, so that when the limiting module is set on the positioning plate, the suction structure can sequentially connect to the top side surface of the limiting module through the through hole array and the secondary through holes.
[0008] In one embodiment, the positioning plate is provided with a mating groove, which is located on the top side surface of the positioning plate.
[0009] In one embodiment, each of the aforementioned limiting modules is configured as a square plate structure.
[0010] In one embodiment, each of the aforementioned limiting modules is magnetically connected to the bottom wall of the positioning plate.
[0011] In one embodiment, the suction structure described above is configured as a funnel-shaped frame.
[0012] In one embodiment, the cutting mechanism includes a drive assembly and a laser cutting unit, wherein the drive assembly is mounted on the top side of the positioning plate, and the laser cutting unit is installed at the output end of the drive assembly.
[0013] In one embodiment, the drive component is provided with two longitudinal linear guides and a transverse linear guide on the plane of the positioning plate; the two longitudinal linear guides are located at both ends of the positioning plate; and the two ends of the transverse linear guide are connected to the output ends of the two longitudinal linear guides.
[0014] In one embodiment, the laser cutting unit described above is mounted on the output end of the transverse linear guide.
[0015] In one embodiment, the above-mentioned laser cutting device for insulating sheets further includes a feeding mechanism and a discharging mechanism, which are respectively disposed at both ends of the working cavity.
[0016] In one embodiment, the housing is provided with a feed port at one end corresponding to the feeding mechanism.
[0017] In one embodiment, the housing is provided with a discharge port at one end corresponding to the feeding mechanism.
[0018] In one embodiment, the above-mentioned feeding mechanism is configured as an active roller assembly.
[0019] In one embodiment, the aforementioned feeding mechanism is configured as a driven roller group.
[0020] Compared with traditional mechanical clamping (such as jigs and pressure plates), the above-mentioned laser cutting device for insulating sheets avoids surface damage, scratches, or deformation of the insulating sheets that may be caused by physical contact and pressure through vacuum adsorption. It is suitable for thin, brittle, or high-surface-smooth insulating materials. The through-hole array design ensures uniform distribution of adsorption force, which ensures that the insulating sheet fits tightly against the positioning plate throughout the cutting process, effectively preventing cutting deviations caused by local lifting or vibration. The modular design of the limiting modules can be added or removed according to the shape of the insulating sheet. Each limiting module also has a secondary through-hole, ensuring the integrity of the adsorption function. Specifically, when it is necessary to cut insulating sheets of different shapes or sizes, it is not necessary to replace the entire positioning plate. By rearranging, adding, or removing the limiting modules, a new "preset station" can be formed, ensuring the consistency of the loading position each time. At the same time, the suction and fixing function can be retained through the secondary through-hole, realizing the modular design of "positioning" and "fixing". Attached Figure Description

[0028] Please see Figures 1 to 5This utility model discloses an insulating sheet laser cutting device 1, which includes a housing 10, a positioning mechanism 20 and a cutting mechanism 30. The positioning mechanism 20 and the cutting mechanism 30 are both installed on the housing 10. The positioning mechanism 20 is arranged along the preset flat plane of the insulating sheet, and the cutting mechanism 30 is arranged on the top side of the positioning mechanism 20. When the insulating sheet is positioned and fixed by the positioning mechanism 20, the cutting mechanism 30 performs laser cutting on the insulating sheet. Specifically, the positioning mechanism 20 includes a positioning plate 21 and a suction structure 22; the housing 10 is provided with a working cavity a, and the positioning plate 21 is located at the bottom of the working cavity a; the suction structure 22 is located on the bottom side of the working cavity a, and one end of the suction structure 22 is connected to the bottom surface of the positioning plate 21, and the other end of the suction structure 22 extends to the outside of the housing 10; based on this, the surface of the positioning plate 21 is provided with a through hole array b, and the through hole array b is connected from the top side of the positioning plate 21 to the suction structure 22 on the bottom side of the positioning plate 21, so that when the insulating sheet is placed at a preset position on the positioning plate 21, the suction structure 22 can suck air and adsorb the insulating sheet on the other side through the through hole array b of the positioning plate 21, thereby realizing the fixed contact between the insulating sheet and the positioning plate 21. More specifically, the positioning plate 21 is provided with a plurality of limiting modules 211, which are arranged in an array on the top side surface of the positioning plate 21. In this way, the positioning plate 21 can add or remove limiting modules 211 according to the shape of the insulating sheet to be cut, thereby providing targeted limiting for special-shaped insulating sheets. Based on this, each limiting module 211 is provided with a plurality of secondary through holes c corresponding to the through hole array b. The plurality of secondary through holes c are provided through each limiting module 211, so that when the limiting module 211 is provided on the positioning plate 21, the suction structure 22 can sequentially connect to the top side surface of the limiting module 211 through the through hole array b and the secondary through holes c. Based on the above configuration, compared with traditional mechanical clamping (such as clamps and pressure plates), the vacuum adsorption of this insulating sheet laser cutting device 1 avoids surface damage, scratches, or deformation of the insulating sheet that may be caused by physical contact and pressure. It is particularly suitable for thin, brittle, or high surface finish requirements of insulating materials. The design of the through-hole array b ensures uniform adsorption force distribution, which ensures that the insulating sheet is tightly attached to the positioning plate 21 throughout the cutting process, effectively preventing cutting deviations caused by local lifting or vibration. The modular design of the limiting module 211 allows for addition or reduction of configurations according to the shape of the insulating sheet. Each limiting module 211 also has a secondary through-hole c, ensuring the integrity of the adsorption function. Specifically, when it is necessary to cut insulating sheets of different shapes or sizes, it is not necessary to replace the entire positioning plate 21. By rearranging, adding, or removing the limiting modules 211, a new "preset station" can be formed, ensuring the consistency of the loading position each time. At the same time, the suction and fixing function can be retained through the secondary through-hole c, realizing the modular design of "positioning" and "fixing".
[0029] Furthermore, the positioning plate 21 is provided with a mating groove d, which is located on the top side surface of the positioning plate 21 to accommodate and support the insulating sheet and several limiting modules 211.
[0030] Furthermore, each limiting module 211 is configured as a square plate structure; in one embodiment, each limiting module 211 is magnetically connected to the bottom wall of the positioning plate 21.
[0031] Furthermore, the suction structure 22 is configured as a funnel-shaped frame, with the wide end of the funnel-shaped frame connected to the bottom side of the positioning plate 21, and the narrowing end of the funnel-shaped frame extending to the outside of the housing 10 through a pipe.
[0032] Furthermore, the cutting mechanism 30 includes a drive assembly and a laser cutting unit 33. The drive assembly is mounted on the top side of the positioning plate 21; the laser cutting unit 33 is installed at the output end of the drive assembly, thereby enabling the drive assembly to drive the laser cutting unit 33 to perform laser cutting on the insulating sheet on the surface of the positioning plate 21.
[0033] Specifically, the drive assembly has two longitudinal linear guides 31 and a transverse linear guide 32 arranged on the plane of the positioning plate 21; the two longitudinal linear guides 31 are located at both ends of the positioning plate 21; the two ends of the transverse linear guide 32 are connected to the output ends of the two longitudinal linear guides 31, thereby enabling the transverse linear guide 32 to reciprocate along the longitudinal linear guides 31. Based on this, the laser cutting unit 33 is installed at the output end of the transverse linear guide 32, thereby realizing dual-axis movement.
[0034] Furthermore, the insulating sheet laser cutting device 1 also includes a feeding mechanism 40 and a discharging mechanism 50, which are respectively disposed at both ends of the working cavity a. Accordingly, the housing 10 is provided with a feed inlet e at one end corresponding to the feeding mechanism 40, and a discharge outlet f at one end corresponding to the discharging mechanism 50. Thus, the feeding mechanism 40 can feed the insulating sheet into the working cavity a through the feed inlet e, and the discharging mechanism 50 can discharge the insulating sheet in the working cavity a to the outside of the housing 10 through the discharge outlet f.
[0035] Furthermore, the feeding mechanism 50 is configured as an active roller assembly to provide conveying power to the insulating sheet at the discharge port f.
[0036] Furthermore, the feeding mechanism 40 is configured as a driven roller group to cooperate with the unloading mechanism 50 to maintain a stable input of insulating sheets into the working cavity a.
[0037] In summary, compared with traditional mechanical clamping (such as jigs and pressure plates), the laser cutting device for insulating sheets disclosed in this utility model avoids surface damage, scratches, or deformation of the insulating sheets that may be caused by physical contact and pressure through vacuum adsorption. It is suitable for thin, brittle, or high-surface-smooth insulating materials. The through-hole array design ensures uniform distribution of adsorption force, which ensures that the insulating sheet adheres tightly to the positioning plate throughout the cutting process, effectively preventing cutting deviations caused by local lifting or vibration. The modular design of the limiting modules can be added or removed according to the shape of the insulating sheet. Each limiting module also has a secondary through hole, ensuring the integrity of the adsorption function. Specifically, when it is necessary to cut insulating sheets of different shapes or sizes, it is not necessary to replace the entire positioning plate. By rearranging, adding, or removing the limiting modules, a new "preset station" can be formed, ensuring the consistency of the loading position each time. At the same time, the suction and fixing function can be retained through the secondary through holes, realizing the modular design of "positioning" and "fixing".
[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
