Description

Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically to a laser beam splitting cutting device. Background Technology

[0002] Laser cutting is used for fabric cutting. It avoids contact with the fabric, eliminates blade wear, and offers advantages such as burr-free edges, standardized dimensions, and minimal error, making it widely used in embroidery machines. Embroidery machines often encounter situations where fabric needs to be cut at two or more stations. Current embroidery machines typically employ two or more lasers, each cutting the fabric at one station. However, this method results in a large number of lasers, increasing the manufacturing cost of the embroidery machine.

[0003] For example, Chinese patent application number 201920291954.0, entitled "A Laser Cutting Machine," includes a frame with a worktable and a laser emitting tube mounted on it. The laser emitting tube is housed within a housing. This laser cutting machine uses a reflector to reflect the laser emitted from the laser emitting tube onto the worktable. In existing technologies, to achieve high cutting efficiency, multiple laser cutting heads are used, with each laser tube corresponding to one laser cutting head. However, this also suffers from the problem of a large number of lasers being used, increasing the manufacturing cost of the embroidery machine.

[0004] To address these issues, some embroidery machines currently employ a mobile laser, where a single laser moves back and forth between two or more workstations to cut the fabric at those workstations. While this method effectively reduces the number of lasers used, thereby lowering the manufacturing cost of the embroidery machine, it suffers from several drawbacks. The laser's movement efficiency is low, especially when the distance between the two cutting workstations is significant, which further impacts the cutting efficiency of the fabric at both workstations. Moreover, the fabric cutting at each workstation can only be performed sequentially at different times, making it impossible to cut fabric at multiple workstations simultaneously. Utility Model Content

[0005] The purpose of this invention is to provide a laser beam splitting cutting device that is not only simple in structure and easy to manufacture, but also capable of simultaneously and continuously cutting fabric at two workstations using a single laser, thereby effectively reducing manufacturing costs.

[0006] The technical solution of this utility model is:

[0007] A laser beam splitting and cutting device, comprising:

[0008] Laser;

[0009] A beam splitter includes two intersecting mirrors at a predetermined angle. A laser beam emitted from a laser is incident on the intersection of the two mirrors of the beam splitter. A portion of the laser beam is reflected by one mirror, and the other portion is reflected by the other, thus splitting the laser beam into two beams. This laser beam splitting cutting device uses the two mirrors of the beam splitter to split a single laser beam into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, this laser beam splitting cutting device can simultaneously cut fabric at two workstations using a single laser, effectively reducing manufacturing costs. Furthermore, the beam splitter is fixed and does not require movement, resulting in a simple structure and easy manufacturing, further reducing production costs.

[0010] Preferably, a dimming mirror is also included, with each mirror corresponding to a reflector. The dimming mirror includes a first lens, which is located on the same side of the beam splitter as the laser. The laser beam reflected by the reflector is reflected by the corresponding first lens to change its direction. In this design, the dimming mirror not only changes the laser direction to accommodate different laser path layouts, but also compensates for errors in the processing angles of the two reflector surfaces by adjusting the mirror's installation angle. This ensures that the laser beam emitted by the laser, after being reflected by the corresponding reflector and the first lens, exits at a set azimuth angle. Furthermore, adjusting the dimming mirror's installation angle changes the angle between the two reflector surfaces of the beam splitter, adapting to different beam splitter applications and improving versatility.

[0011] Preferably, a dimming mirror is also included, with each mirror corresponding to a reflector. The dimming mirror includes a first lens and a second lens. The first lens and the laser are located on the same side of the beam splitter, and the first lens and the laser are located on the same side of the corresponding second lens. The laser light reflected by the reflector passes sequentially through the corresponding first and second lenses to change its direction. In this design, the dimming mirror not only changes the laser direction to adapt to different laser path layouts, but also compensates for errors in the processing angles of the two reflector surfaces of the beam splitter by adjusting the mirror's installation angle. This ensures that a laser beam emitted from the laser, after being reflected by the corresponding reflector, the first lens, and the second lens, exits at a set azimuth angle. Furthermore, adjusting the mirror's installation angle changes the angle between the two reflector surfaces of the beam splitter to adapt to different beam splitter applications, improving versatility.

[0013] The focusing lens corresponds one-to-one with the reflecting mirror surface;

[0014] A laser path adjustment unit, corresponding one-to-one with a focusing lens, includes at least one adjustment lens. The laser light reflected from the reflective mirror is reflected by the corresponding adjustment lens to the corresponding focusing lens for focusing. Thus, the laser path can be adjusted using the adjustment lenses of the laser path adjustment unit, thereby adjusting the position of the focusing lens and the cutting area to adapt to different cutting needs.

[0015] Preferably, the laser path adjustment unit also includes a protective tube that extends along the path of the laser. In this way, the laser light entering the laser path adjustment unit will be transmitted within the corresponding protective tube, effectively preventing contact between the laser and objects or personnel, thus protecting both the objects and the operators.

[0017] The focusing lens corresponds one-to-one with the reflecting mirror surface;

[0018] A laser path adjustment unit, corresponding one-to-one with a focusing lens, includes at least one adjustment lens. The laser reflected by the reflecting mirror passes through the corresponding first lens and the adjustment lens before being reflected to the corresponding focusing lens. Thus, the laser path can be adjusted using the adjustment lenses of the laser path adjustment unit, thereby adjusting the position of the focusing lens and the cutting area to adapt to different cutting needs.

[0019] Preferably, the laser path adjustment unit also includes a protective tube that extends along the path of the laser.

[0021] The focusing lens corresponds one-to-one with the reflecting mirror surface;

[0022] A laser path adjustment unit, corresponding one-to-one with a focusing lens, includes at least one adjustment lens. The laser reflected from the reflective mirror passes sequentially through the corresponding first lens, second lens, and adjustment lens before being reflected to the corresponding focusing lens. Thus, the laser path can be adjusted using the adjustment lenses of the laser path adjustment unit, thereby adjusting the position of the focusing lens and the cutting area to adapt to different cutting needs.

[0023] Preferably, the laser path adjustment unit also includes a protective tube that extends along the path of the laser. In this way, the laser light entering the laser path adjustment unit will be transmitted within the corresponding protective tube, effectively preventing contact between the laser and objects or personnel, thus protecting both the objects and the operators.

[0024] Preferably, the two reflective mirrors are symmetrically distributed along a single laser beam emitted by the laser. The laser beam emitted by the laser is split into two symmetrically distributed laser beams by the two reflective mirrors of the beam splitter, which is beneficial for practical layout and fabrication needs.

[0025] The advantages of this invention are: it is not only simple in structure and easy to manufacture, but also can use a single laser to continuously cut the fabric at two workstations at the same time, thereby effectively reducing the manufacturing cost. Attached Figure Description

[0035] Mirror base 5;

[0036] Dimming mirror 6, first lens 6.1, second lens 6.2. Detailed Implementation

[0037] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a laser beam splitting cutting device includes a laser 1 and a beam splitter 2.

[0038] The beam splitter 2 is fixedly mounted. The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect. In this embodiment, the beam splitter 2 is fixed on the mirror mount 5.

[0039] A laser beam emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1 of beam splitter 2. Part of the laser beam emitted by laser 1 is reflected by one reflecting mirror 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thereby splitting the laser beam emitted by laser 1 into two laser beams.

[0040] This embodiment of a laser beam splitting cutting device uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, this laser beam splitting cutting device can simultaneously and continuously cut the fabric at two workstations using a single laser 1, thereby effectively reducing manufacturing costs. On the other hand, the beam splitter 2 is fixed and does not need to be moved, thus its structure is simple and easy to manufacture, further reducing manufacturing costs.

[0041] In this embodiment, laser 1 is located above beam splitter 2. A laser beam emitted by laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the laser beam emitted by laser 1. The included angle between the two reflecting mirrors 2.1 of beam splitter 2 is 90 degrees. Thus, the laser beam emitted by laser 1 is split into two symmetrically distributed laser beams by the two reflecting mirrors 2.1 of beam splitter 2, and the two laser beams exit in a horizontal direction.

[0042] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0043] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be set to other angles as needed, such as 80 degrees, 100 degrees, 120 degrees, or 130 degrees. The two reflecting mirrors can be symmetrically distributed or asymmetrically distributed.

[0044] Furthermore, a laser beam splitting and cutting device also includes a focusing lens 3 and a laser path adjustment unit 4. The focusing lens 3 corresponds one-to-one with the reflecting mirror 2.1. The laser path adjustment unit 4 corresponds one-to-one with the focusing lens 3. The laser path adjustment unit 4 includes at least one adjusting lens 4.1. In this embodiment, the adjusting lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding adjusting lens 4.1 to the corresponding focusing lens 3 for focusing. After passing through the focusing lens 3, the laser can cut the fabric on the embroidery machine. Thus, the laser path can be adjusted by the adjusting lens 4.1 of the laser path adjustment unit 4, thereby adjusting the position of the focusing lens 3 and the cutting part to adapt to different cutting needs.

[0045] Furthermore, such as Figure 1 As shown, the laser path adjustment unit 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light entering the laser path adjustment unit 4 will be transmitted within the corresponding protective tube 4.2, effectively preventing contact between objects or personnel and the laser, thereby protecting the objects and operators.

[0046] In actual manufacturing, the adjustment lenses 4.1 of the same laser path adjustment unit 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same laser path adjustment unit 4. In this embodiment, there are two adjustment lenses 4.1 of the same laser path adjustment unit 4.

[0047] In one embodiment, the same laser path adjustment unit 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 3. The laser reflected by the reflecting mirror 2.1 is reflected twice by the two adjustment lenses 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the laser path adjustment unit 4 has two protective tubes 4.2, one of which is located between the two adjustment lenses 4.1, and the other is located between the beam splitter 2 and the adjustment lens 4.1 of the adjacent beam splitter 2.

[0048] In another embodiment, the same laser path adjustment unit 4 includes an adjustment lens 4.1, which is located above the focusing lens 3. The laser reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the protective tube 4.2 of the laser path adjustment unit 4 is a single tube, which is located between the beam splitter 2 and the adjustment lens 4.1.

[0049] Specific embodiment two, such as Figure 3 As shown, a laser beam splitting cutting device includes a laser 1, a dimmer mirror 6, and a beam splitter 2.

[0050] The beam splitter 2 is fixedly mounted. The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect. In this embodiment, the beam splitter 2 is fixed on the mirror mount 5.

[0051] A laser beam emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1 of beam splitter 2. Part of the laser beam emitted by laser 1 is reflected by one reflecting mirror 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thereby splitting the laser beam emitted by laser 1 into two laser beams.

[0052] The dimming mirror 6 corresponds one-to-one with the reflecting mirror 2.1. The dimming mirror 6 includes a first lens 6.1. The first lens 6.1 and the laser 1 are located on the same side of the beam splitter 2. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding first lens 6.1 to change the direction of the laser.

[0053] This embodiment of a laser beam splitting cutting device uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, this laser beam splitting cutting device can simultaneously and continuously cut the fabric at two workstations using a single laser 1, thereby effectively reducing manufacturing costs. Furthermore, the beam splitter 2 is fixed and does not need to be moved, resulting in a simple structure, convenient manufacturing, and further reduced manufacturing costs.

[0054] On the other hand, in this embodiment, by setting the dimming mirror 6, not only can the laser direction be changed to adapt to the layout requirements of different laser paths, but also the error in the processing angle of the two reflecting mirrors 2.1 of the beam splitter 2 can be compensated by adjusting the installation angle of the dimming mirror 6. This ensures that the laser beam emitted by the laser 1, after being reflected by the corresponding reflecting mirror 2.1 and the first lens 6.1, can be emitted at a set azimuth angle. In addition, the angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be changed by adjusting the installation angle of the dimming mirror 6 to adapt to the usage requirements of different beam splitters 2 and improve versatility.

[0055] In this embodiment, laser 1 is located above beam splitter 2. A laser beam emitted by laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the laser beam emitted by laser 1. Thus, the laser beam emitted by laser 1 is split into two symmetrically distributed laser beams by the two reflecting mirrors 2.1 of beam splitter 2. Simultaneously, the laser beam reflected by the first lens 6.1 can be adjusted to exit horizontally by adjusting the mounting angle of the first lens 6.1.

[0056] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0057] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be set to 80 degrees, 100 degrees, 120 degrees, 130 degrees, or 140 degrees, etc., as needed. The two reflecting mirrors can be symmetrically distributed or asymmetrically distributed.

[0058] Furthermore, such as Figure 3As shown, a laser beam splitting and cutting device further includes a focusing lens 3 and a laser path adjustment unit 4. The focusing lens 3 corresponds one-to-one with the reflecting mirror 2.1. The laser path adjustment unit 4 corresponds one-to-one with the focusing lens 3. The laser path adjustment unit 4 includes at least one adjusting lens 4.1. In this embodiment, the adjusting lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 is reflected by the corresponding first lens 6.1 and the adjusting lens 4.1 to the corresponding focusing lens 3. After passing through the focusing lens 3, the laser can cut the fabric on the embroidery machine. Thus, the laser path can be adjusted by the adjusting lens 4.1 of the laser path adjustment unit 4, thereby adjusting the position of the focusing lens 3 and the cutting part to adapt to different cutting needs.

[0059] Furthermore, such as Figure 3 As shown, the laser path adjustment unit 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light entering the laser path adjustment unit 4 will be transmitted within the corresponding protective tube 4.2, effectively preventing contact between objects or personnel and the laser, thereby protecting the objects and operators.

[0060] In actual manufacturing, the adjustment lenses 4.1 of the same laser path adjustment unit 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same laser path adjustment unit 4. In this embodiment, there are two adjustment lenses 4.1 of the same laser path adjustment unit 4.

[0061] In one embodiment, the same laser path adjustment unit 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 3. The laser reflected by the reflecting mirror 2.1 is reflected twice by the two adjustment lenses 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the laser path adjustment unit 4 has two protective tubes 4.2, one of which is located between the two adjustment lenses 4.1, and the other is located between the beam splitter 2 and the adjustment lens 4.1 of the adjacent first lens 6.1.

[0062] In another embodiment, the same laser path adjustment unit 4 includes an adjustment lens 4.1 located above the focusing lens 3. The laser light reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the protective tube 4.2 of the laser path adjustment unit 4 is a single tube located between the first lens 6.1 and the adjustment lens 4.1.

[0063] Specific embodiment three, such as Figure 4 As shown, a laser beam splitting cutting device includes a laser 1, a dimmer mirror 6, and a beam splitter 2.

[0064] The beam splitter 2 is fixedly mounted. The beam splitter 2 includes two reflecting mirrors 2.1 that are at a predetermined angle to each other and intersect. In this embodiment, the beam splitter 2 is fixed on the mirror mount 5.

[0065] A laser beam emitted by laser 1 is incident at the intersection of two reflecting mirrors 2.1 of beam splitter 2. Part of the laser beam emitted by laser 1 is reflected by one reflecting mirror 2.1, and the other part of the laser beam is reflected by the other reflecting mirror 2.1, thereby splitting the laser beam emitted by laser 1 into two laser beams.

[0066] The dimming mirror 6 corresponds one-to-one with the reflecting mirror 2.1. The dimming mirror 6 includes a first lens 6.1 and a second lens 6.2. The first lens 6.1 and the laser 1 are located on the same side of the beam splitter 2. The first lens 6.1 and the laser 1 are located on the same side of the corresponding second lens 6.2. The laser reflected by the reflecting mirror 2.1 is reflected sequentially by the corresponding first lens 6.1 and second lens 6.2 to change the direction of the laser.

[0067] This embodiment of a laser beam splitting cutting device uses two reflecting mirrors 2.1 of a beam splitter 2 to split a laser beam emitted by a laser 1 into two continuously output laser beams. Each laser beam can continuously cut the fabric at one workstation. Therefore, this laser beam splitting cutting device can simultaneously and continuously cut the fabric at two workstations using a single laser 1, thereby effectively reducing manufacturing costs. Furthermore, the beam splitter 2 is fixed and does not need to be moved, resulting in a simple structure, convenient manufacturing, and further reduced manufacturing costs.

[0068] On the other hand, in this embodiment, by setting the dimming mirror 6, not only can the laser direction be changed to adapt to the layout requirements of different laser paths, but also the error in the processing angle of the two reflecting mirrors 2.1 of the beam splitter 2 can be compensated by adjusting the installation angle of the dimming mirror 6. This ensures that the laser beam emitted by the laser 1 can be emitted at a set azimuth angle after being reflected by the corresponding reflecting mirror 2.1, the first lens 6.1, and the second lens 6.2. In addition, the angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be changed by adjusting the installation angle of the dimming mirror 6 to adapt to the usage requirements of different beam splitters 2 and improve versatility.

[0069] In this embodiment, laser 1 is located above beam splitter 2. A laser beam emitted by laser 1 enters vertically at the intersection of the two reflecting mirrors 2.1 of beam splitter 2. The two reflecting mirrors 2.1 are symmetrically distributed along the laser beam emitted by laser 1. Thus, the laser beam emitted by laser 1 is split into two symmetrically distributed laser beams by the two reflecting mirrors 2.1 of beam splitter 2. At the same time, by adjusting the installation angle of the first lens 6.1 and the second lens 6.2 of the same dimming mirror 6, the laser beam reflected after passing through the first lens 6.1 and the second lens 6.2 in sequence is emitted horizontally.

[0070] It should be noted that the positions of laser 1 and beam splitter 2 can also be arranged in other orientations according to actual needs. For example, laser 1 and beam splitter 2 can be arranged in front of each other, and a beam of laser emitted by laser 1 can be horizontally incident on the intersection of the two reflecting mirrors 2.1 of beam splitter 2.

[0071] The included angle between the two reflecting mirrors 2.1 of the beam splitter 2 can be set to 80 degrees, 100 degrees, 120 degrees, 130 degrees, or 140 degrees, etc., as needed. The two reflecting mirrors can also be asymmetrically distributed.

[0072] In this embodiment, as Figure 4 As shown, a laser beam splitting and cutting device further includes a focusing lens 3 and a laser path adjustment unit 4. The focusing lens 3 corresponds one-to-one with the reflecting mirror 2.1. The laser path adjustment unit 4 corresponds one-to-one with the focusing lens 3. The laser path adjustment unit 4 includes at least one adjustment lens 4.1. In this embodiment, the adjustment lens 4.1 is a reflecting lens. The laser reflected by the reflecting mirror 2.1 passes sequentially through the corresponding first lens 6.1, second lens 6.2, and adjustment lens 4.1 before being reflected back to the corresponding focusing lens 3. After passing through the focusing lens 3, the laser can cut the fabric on the embroidery machine. Thus, the laser path can be adjusted by the adjustment lens 4.1 of the laser path adjustment unit 4, thereby adjusting the position of the focusing lens 3 and the cutting part to adapt to different cutting needs.

[0073] Furthermore, such as Figure 4 As shown, the laser path adjustment unit 4 also includes a protective tube 4.2, which extends along the path of the laser. Thus, the laser light entering the laser path adjustment unit 4 will be transmitted within the corresponding protective tube 4.2, effectively preventing contact between objects or personnel and the laser, thereby protecting the objects and operators.

[0074] In actual manufacturing, the adjustment lenses 4.1 of the same laser path adjustment unit 4 can be set according to actual needs. For example, there can be one, two, three or more adjustment lenses 4.1 of the same laser path adjustment unit 4. In this embodiment, there are two adjustment lenses 4.1 of the same laser path adjustment unit 4.

[0075] In one embodiment, the same laser path adjustment unit 4 includes two adjustment lenses 4.1, one of which is located above the focusing lens 3. The laser reflected by the reflecting mirror 2.1 is reflected twice by the two adjustment lenses 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the laser path adjustment unit 4 has two protective tubes 4.2, one of which is located between the two adjustment lenses 4.1, and the other is located between the beam splitter 2 and the adjustment lens 4.1 of the adjacent second lens 6.2.

[0076] In another embodiment, the same laser path adjustment unit 4 includes an adjustment lens 4.1 located above the focusing lens 3. The laser light reflected by the reflecting mirror 2.1 is reflected by the adjustment lens 4.1 of the corresponding laser path adjustment unit 4, and then enters the focusing lens 3 from top to bottom for focusing. In this embodiment, the protective tube 4.2 of the laser path adjustment unit 4 is a single tube located between the second lens 6.2 and the adjustment lens 4.1.

[0077] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
