Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a multi-beam laser cutting device for embroidery machines. Background Technology

[0002] Currently, laser cutting devices are widely used in embroidery machines for fabric cutting. Laser cutting does not come into contact with the fabric, eliminating blade wear issues and resulting in burr-free edges, standardized dimensions, and minimal error. When using laser cutting devices in embroidery machines, it is often necessary to cut fabric at multiple stations. Currently, one laser cutting device is typically used for each station, leading to a large number of laser cutting devices and increasing the manufacturing cost of the embroidery machine.

[0003] To address the aforementioned 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, the fabric cutting at each workstation can only be performed sequentially at different times, making it impossible to cut fabric at multiple workstations simultaneously.

[0004] For example, Chinese Patent Publication No. CN112207451A, published on October 15, 2008, is entitled "A Fabric Laser Cutting Machine". This application can realize the up-down, back-and-forth, and left-and-right movement of the laser head for cutting fabric. Although it can move the laser head to different work positions to cut fabric at different work positions, it also has the problem of not being able to cut fabric at multiple work positions at the same time. Utility Model Content

[0005] The purpose of this invention is to provide a multi-beam laser cutting device for embroidery machines that can not only reduce the amount of laser generators used to save costs, but also cut fabrics at multiple workstations simultaneously to ensure production efficiency.

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

[0007] A multi-beam laser cutting device for an embroidery machine includes:

[0008] A laser generator includes at least two laser emission ports, each capable of emitting a laser beam;

[0009] At least two focusing lenses, each corresponding to a laser emission port;

[0010] A laser path adjustment unit, corresponding one-to-one with a laser emission port, includes at least one reflector. The reflector of the laser path adjustment unit reflects a laser beam emitted from the corresponding laser emission port to the corresponding focusing lens. In this multi-emission laser cutting device for an embroidery machine, when the laser generator is working, each laser emission port can emit a laser beam, thus allowing at least two laser beams to be emitted simultaneously. Each laser beam emitted from a laser emission port is reflected by the reflector of the corresponding laser path adjustment unit to the corresponding focusing lens for focusing, and then cuts the fabric at the corresponding workstation. This allows for simultaneous cutting of fabric at at least two workstations of the embroidery machine using the same laser generator, thereby reducing the number of laser generators required and saving costs. It also enables simultaneous cutting of fabric at multiple workstations to ensure production efficiency.

[0011] Preferably, the laser generator also includes a columnar generator body, which is vertically arranged. Because the generator body is columnar and vertically arranged, the space in the vertical direction can be utilized to arrange the laser generator, effectively reducing the space occupied by the laser generator in the horizontal direction. Simultaneously, it helps to reduce the spacing between focusing lenses. This arrangement of the laser generator is particularly suitable for applications in embroidery machines where the horizontal space for the laser cutting device is limited.

[0012] Preferably, some of the laser emission ports are located at the bottom of the generator body and emit lasers downwards, while the other portion of the laser emission ports are located at the top of the generator body and emit lasers upwards.

[0013] Preferably, the laser path adjustment unit corresponding to the laser emission port at the bottom of the generator body includes at least two reflectors, one of which is located below the corresponding laser emission port, and the other is located above the corresponding focusing lens. In this way, the laser path can be adjusted using the reflectors of the laser path adjustment unit, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0014] Preferably, the laser path adjustment unit corresponding to the laser emission port at the top of the generator body includes at least two reflectors, one of which is located above the corresponding laser emission port, and the other is located above the corresponding focusing lens. In this way, the laser path can be adjusted using the reflectors of the laser path adjustment unit, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0015] Preferably, the laser path adjustment unit corresponding to the laser emission port at the top of the generator body includes five reflectors. The first reflector is located above the corresponding laser emission port, the second reflector is at the same height as the first, the third reflector is below the second, the fourth reflector is at the same height as the third, and the fifth reflector is located above the corresponding focusing lens, and at the same height as the fourth. The laser emitted from the laser emission port passes sequentially through these five reflectors before entering the corresponding focusing lens. In this way, the laser path can be adjusted using the reflectors of the laser path adjustment unit, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0016] Preferably, the laser generator also includes a columnar generator body, which is horizontally positioned. Because the generator body is columnar and horizontally positioned, the space in the horizontal direction can be utilized to arrange the laser generator, effectively reducing the space occupied by the laser generator in the vertical direction. This arrangement of the laser generator is particularly suitable for applications in embroidery machines where the vertical space for arranging the laser cutting device is limited, but the horizontal space is sufficient.

[0017] Preferably, some of the laser emission ports are located at the left end of the generator body, and the other portion are located at the right end. The laser emission ports at the left end of the generator body emit laser light towards the left side of the generator body, and the laser emission ports at the right end emit laser light towards the right side of the generator body. This arrangement of the laser emission ports and the direction of laser emission from them allows the laser cutting device to adapt to the actual cutting needs of the embroidery machine.

[0018] Preferably, the laser path adjustment unit also includes an outer protective tube distributed along the laser path, with the laser emitted from the laser outlet being transmitted within the outer protective tube of the corresponding laser path adjustment unit. In this way, on the one hand, the outer protective tube ensures that the laser path is not obstructed by foreign objects; on the other hand, it effectively prevents objects or personnel from coming into contact with the laser, thus protecting both the objects and the operators.

[0019] Preferably, the laser generator, focusing lens, and laser path adjustment unit are all mounted on the frame of the embroidery machine.

[0020] The beneficial effects of this invention are as follows: When the laser generator is working, each laser output port can emit a laser beam, thus allowing at least two laser beams to be emitted simultaneously. Each laser beam emitted from each output port is reflected by the mirror of the corresponding laser path adjustment unit and focused by the corresponding focusing lens, then cuts the fabric at the corresponding workstation. This enables the simultaneous cutting of fabric at at least two workstations on the embroidery machine using the same laser generator, thereby reducing the number of laser generators required and saving costs. Furthermore, it allows for simultaneous cutting of fabric at multiple workstations, ensuring production efficiency. Attached Figure Description

[0026] Focusing on lens 2;

[0027] Laser path adjustment unit 3, reflector 3.1, outer protective tube 3.2. Detailed Implementation

[0028] Specific Implementation Example 1, such as Figure 1 As shown, a multi-beam laser cutting device for an embroidery machine includes a laser generator 1, at least two focusing lenses 2, and a laser path adjustment unit 3.

[0029] The laser generator 1 includes at least two laser emission ports 1.1. For example, the laser generator 1 includes two, three, or four laser emission ports 1.1. Each laser emission port 1.1 can emit a laser beam. When the laser generator 1 is operating, each laser emission port 1.1 emits a laser beam simultaneously. The laser emission ports 1.1 can be arranged on the same side of the laser generator 1, or they can be arranged on both sides of the laser generator 1 as needed.

[0030] The focusing lens 2 corresponds one-to-one with the laser emission port 1.1.

[0031] The laser path adjustment unit 3 corresponds one-to-one with the laser emission port 1.1. The laser path adjustment unit 3 also corresponds one-to-one with the focusing lens 2. The laser path adjustment unit 3 includes at least one reflector 3.1, which reflects a laser beam emitted from the corresponding laser emission port 1.1 to the corresponding focusing lens 2.

[0032] In this embodiment of a multi-beam laser cutting device for an embroidery machine, when the laser generator 1 is working, each laser emission port 1.1 can emit a laser beam, thus enabling the simultaneous emission of at least two laser beams. Each laser beam emitted from the laser emission port 1.1 is reflected by the reflector 3.1 of the corresponding laser path adjustment unit 3 and focused by the corresponding focusing lens 2, then cuts the fabric at the corresponding workstation. This allows for the simultaneous cutting of fabric at at least two workstations of the embroidery machine using the same laser generator 1, thereby reducing the number of laser generators 1 required to save costs, and enabling simultaneous cutting of fabric at multiple workstations to ensure production efficiency.

[0033] Specific embodiment two, such as Figure 1 , Figure 2 As shown, a multi-beam laser cutting device for an embroidery machine includes a laser generator 1, at least two focusing lenses 2, and a laser path adjustment unit 3.

[0034] The laser generator 1 includes at least two laser emission ports 1.1. For example, the laser generator 1 includes two, three, or four laser emission ports 1.1. Each laser emission port 1.1 can emit a laser beam. When the laser generator 1 is in operation, each laser emission port 1.1 emits a laser beam simultaneously.

[0035] In this embodiment, the laser generator 1 further includes a columnar generator body 1.2, which is vertically distributed. In this embodiment, the vertical distribution of the generator body 1.2 means that the length direction of the columnar generator body 1.2 is vertically distributed.

[0036] The focusing lens 2 corresponds one-to-one with the laser emission port 1.1.

[0037] The laser path adjustment unit 3 corresponds one-to-one with the laser emission port 1.1. The laser path adjustment unit 3 also corresponds one-to-one with the focusing lens 2. The laser path adjustment unit 3 includes at least one reflector 3.1, which reflects a laser beam emitted from the corresponding laser emission port 1.1 to the corresponding focusing lens 2.

[0038] In this embodiment of a multi-beam laser cutting device for an embroidery machine, when the laser generator 1 is working, each laser emission port 1.1 can emit a laser beam, thus enabling the simultaneous emission of at least two laser beams. Each laser beam emitted from the laser emission port 1.1 is reflected by the reflector 3.1 of the corresponding laser path adjustment unit 3 and focused by the corresponding focusing lens 2, then cuts the fabric at the corresponding workstation. This allows for the simultaneous cutting of fabric at at least two workstations of the embroidery machine using the same laser generator 1, thereby reducing the number of laser generators 1 required to save costs, and enabling simultaneous cutting of fabric at multiple workstations to ensure production efficiency.

[0039] On the other hand, since the generator body 1.2 of the laser generator 1 is columnar and vertically distributed, the space in the vertical direction can be utilized to arrange the laser generator 1, effectively reducing the space occupied by the laser generator 1 in the horizontal direction. Simultaneously, it helps to reduce the spacing between the focusing lenses 2. This arrangement of the laser generator 1 is particularly suitable for applications in embroidery machines where the horizontal space for arranging the laser cutting device is limited.

[0040] Specifically, the laser generator 1, focusing lens 2, and laser path adjustment unit 3 are all mounted on the frame of the embroidery machine. The laser generator 1, focusing lens 2, and laser path adjustment unit 3 can each be mounted separately on the frame, or they can be first mounted on the same bracket, and then the laser generator 1, focusing lens 2, and laser path adjustment unit 3 of a multi-emission laser cutting device for an embroidery machine can be mounted together on the frame via the bracket.

[0041] Furthermore, such as Figure 1 , Figure 2 As shown, the laser path adjustment unit 3 also includes an outer protective tube 3.2 distributed along the laser path. The laser emitted from the laser outlet 1.1 is transmitted within the corresponding outer protective tube 3.2 of the laser path adjustment unit 3. In this way, on the one hand, the outer protective tube 3.2 can ensure that the laser path is not blocked by foreign objects, and on the other hand, it can effectively prevent objects or personnel from coming into contact with the laser, thereby protecting the objects and operators.

[0042] Furthermore, a portion of the laser emission ports 1.1 are located at the bottom of the generator body 1.2 and emit lasers downwards, while the other portion of the laser emission ports 1.1 are located at the top of the generator body 1.2 and emit lasers upwards.

[0043] In this embodiment, as Figure 1 , Figure 2As shown, the laser generator 1 has two laser emission ports 1.1. One laser emission port 1.1 is located at the bottom of the generator body 1.2 and emits laser downwards, while the other laser emission port 1.1 is located at the top of the generator body 1.2 and emits laser upwards.

[0044] Furthermore, the laser path adjustment unit 3, corresponding to the laser emission port 1.1 at the bottom of the generator body 1.2, includes at least two reflectors 3.1. One reflector 3.1 is located below the corresponding laser emission port 1.1, and the other reflector 3.1 is located above the corresponding focusing lens 2. Thus, the laser path can be adjusted using the reflectors 3.1 of the laser path adjustment unit 3, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0045] In one example, such as Figure 1 , Figure 2 As shown, the laser path adjustment unit 3, corresponding to the laser emission port 1.1 at the bottom of the generator body 1.2, includes at least three reflectors 3.1. The first reflector 3.1 is located below the corresponding laser emission port 1.1, the third reflector 3.1 is located above the corresponding focusing lens 2, and the second reflector 3.1 is used to reflect the laser emitted from the first reflector 3.1 onto the third reflector 3.1. In actual operation, a laser beam is emitted downwards from the laser emission port 1.1 at the bottom of the generator body 1.2. This laser beam passes sequentially through the first reflector 3.1, the second reflector 3.1, and the third reflector 3.1, and then enters the corresponding focusing lens 2 from top to bottom for focusing, cutting the fabric below the focusing lens 2. In this example, an outer protective tube 3.2 is arranged between each reflector 3.1.

[0046] Furthermore, the laser path adjustment unit 3, corresponding to the laser emission port 1.1 at the top of the generator body 1.2, includes at least two reflectors 3.1. One reflector 3.1 is located above the corresponding laser emission port 1.1, and the other reflector 3.1 is located above the corresponding focusing lens 2. Thus, the laser path can be adjusted using the reflectors 3.1 of the laser path adjustment unit 3, thereby adjusting the position of the fabric cutting area to suit actual cutting needs.

[0047] In one example, such as Figure 1 , Figure 2As shown, the laser path adjustment unit 3, corresponding to the laser emission port 1.1 at the top of the generator body 1.2, includes five reflectors 3.1. The first reflector 3.1 is located above the corresponding laser emission port 1.1; the second reflector 3.1 is at the same height as the first reflector 3.1; the third reflector 3.1 is located below the second reflector 3.1; the fourth reflector 3.1 is at the same height as the third reflector 3.1; and the fifth reflector 3.1 is located above the corresponding focusing lens 2, and at the same height as the fourth reflector 3.1. The laser emitted from the laser emission port 1.1 passes sequentially through the first to fifth reflectors 3.1 and then enters the corresponding focusing lens 2 for focusing, cutting the fabric below the focusing lens 2. In this example, an outer protective tube 3.2 is arranged between each reflector 3.1.

[0048] Specific embodiment three, such as Figure 3 As shown, a multi-beam laser cutting device for an embroidery machine includes a laser generator 1, at least two focusing lenses 2, and a laser path adjustment unit 3.

[0049] The laser generator 1 includes at least two laser emission ports 1.1. For example, the laser generator 1 includes two, three, or four laser emission ports 1.1. Each laser emission port 1.1 can emit a laser beam. When the laser generator 1 is in operation, each laser emission port 1.1 emits a laser beam simultaneously.

[0050] In this embodiment, the laser generator 1 further includes a columnar generator body 1.2, which is horizontally distributed. In this embodiment, the horizontal distribution of the generator body 1.2 means that the length direction of the columnar generator body 1.2 is horizontally distributed.

[0051] The focusing lens 2 corresponds one-to-one with the laser emission port 1.1.

[0052] The laser path adjustment unit 3 corresponds one-to-one with the laser emission port 1.1. The laser path adjustment unit 3 also corresponds one-to-one with the focusing lens 2. The laser path adjustment unit 3 includes at least one reflector 3.1, which reflects a laser beam emitted from the corresponding laser emission port 1.1 to the corresponding focusing lens 2.

[0053] In this embodiment of a multi-beam laser cutting device for an embroidery machine, when the laser generator 1 is working, each laser emission port 1.1 can emit a laser beam, thus enabling the simultaneous emission of at least two laser beams. Each laser beam emitted from the laser emission port 1.1 is reflected by the reflector 3.1 of the corresponding laser path adjustment unit 3 and focused by the corresponding focusing lens 2, then cuts the fabric at the corresponding workstation. This allows for the simultaneous cutting of fabric at at least two workstations of the embroidery machine using the same laser generator 1, thereby reducing the number of laser generators 1 required to save costs, and enabling simultaneous cutting of fabric at multiple workstations to ensure production efficiency.

[0054] On the other hand, since the generator body 1.2 of the laser generator 1 is columnar and horizontally distributed, the space in the horizontal direction can be utilized to arrange the laser generator 1, effectively reducing the space occupied by the laser generator 1 in the vertical direction. This arrangement of the laser generator 1 is particularly suitable for use in embroidery machines where the space for arranging the laser cutting device in the vertical direction is limited, but the space in the horizontal direction is sufficient.

[0055] Specifically, the laser generator 1, focusing lens 2, and laser path adjustment unit 3 are all mounted on the frame of the embroidery machine. The laser generator 1, focusing lens 2, and laser path adjustment unit 3 can each be mounted separately on the frame, or they can be first mounted on the same bracket, and then the laser generator 1, focusing lens 2, and laser path adjustment unit 3 of a multi-emission laser cutting device for an embroidery machine can be mounted together on the frame via the bracket.

[0056] Furthermore, such as Figure 3 As shown, some of the laser emission ports 1.1 are located at the left end of the generator body 1.2, while the other portion are located at the right end. The laser emission ports 1.1 located at the left end of the generator body 1.2 emit laser light towards the left side of the generator body 1.2, and the laser emission ports 1.1 located at the right end of the generator body 1.2 emit laser light towards the right side of the generator body 1.2. This arrangement of the laser emission ports 1.1 and the direction in which they emit laser light facilitates the adaptation of the laser cutting device to the actual cutting needs of the embroidery machine.

[0057] In this embodiment, the length of the columnar generator body 1.2 is horizontally distributed along the left-right direction of the embroidery machine. The laser generator 1 has two laser emission ports 1.1, one of which is located at the left end of the generator body 1.2, and the other is located at the left end of the generator body 1.2.

[0058] Furthermore, such as Figure 3As shown, the laser path adjustment unit 3 also includes an outer protective tube 3.2 distributed along the laser path. The laser emitted from the laser outlet 1.1 is transmitted within the corresponding outer protective tube 3.2 of the laser path adjustment unit 3. In this way, on the one hand, the outer protective tube 3.2 can ensure that the laser path is not blocked by foreign objects, and on the other hand, it can effectively prevent objects or personnel from coming into contact with the laser, thereby protecting the objects and operators.

[0059] In this embodiment, the laser path adjustment unit 3 includes two reflectors 3.1. The first reflector 3.1 is located on one side of the corresponding laser emission port 1.1, and the other reflector 3.1 is located above the corresponding focusing lens 2. During actual operation, a laser beam is emitted downwards from the laser emission port 1.1. This laser beam passes through the two reflectors 3.1 sequentially and then enters the corresponding focusing lens 2 from top to bottom for focusing, cutting the fabric below the focusing lens 2. In this example, an outer protective tube 3.2 is arranged between the laser emission port 1.1 and an adjacent reflector 3.1, and an outer protective tube 3.2 is also arranged between the two reflectors 3.1.

[0060] 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.
