Description

TECHNICAL FIELD

[0001] The utility model relates to laser cutting device technical field, concretely relates to a light splitting type laser cutting device for embroidery machine. BACKGROUND

[0002] Laser cutting is used for cloth cutting, does not have contact with cloth, does not exist blade wear problem, has no burr, size standard, error small etc. characteristics, and is widely used in embroidery machine. In embroidery machine, often need to cut the cloth of two or more stations, for this condition, the current embroidery machine generally adopts the following mode: adopt two or more lasers, each laser cuts the cloth of one station, this mode exists laser consumption, increases the manufacturing cost of embroidery machine.

[0003] In order to solve the above problem, at present some embroidery machines adopt a mobile laser, that is, one laser reciprocates in two or more stations to cut the cloth of two or more stations, this mode can effectively reduce the consumption of laser, thereby reducing the manufacturing cost of embroidery machine, but it has low laser moving efficiency, especially when the distance between two cutting stations is large, it will affect the cutting efficiency of the cloth of two stations, and the cloth cutting of each station can only be carried out in turn at different times, and the cloth of multiple stations cannot be cut at the same time.

[0004] Further, in order to solve the problem of mobile laser, some inventors have made improvements, for example, Chinese patent publication No. CN 111843242 A, the name of invention is double-head laser cutting machine, which comprises a laser, a light splitter, a first cutting galvanometer and a second cutting galvanometer, the light splitter divides a beam of laser emitted by the laser into two beams of laser transmitted to the first cutting galvanometer and the second cutting galvanometer, so that one beam of light emitted by the laser can be divided into two beams by the light splitter for cutting. The application divides one beam of light into two beams for cutting by the light splitter, so that one laser can cut multiple stations of cloth at the same time, but it needs to increase the power of the laser (to two times or more of the original), which also increases the manufacturing cost of the embroidery machine, specifically,

[0005] The current light splitter is composed of incident and exit slits, mirrors and dispersion elements, which can divide one beam of incident light into two or more beams, but the sum of the power of each beam divided by the light splitter is the same as the power of the incident light, for example, a 30W laser emits a 30W laser, which is divided into two beams by the light splitter, each beam is a 15W laser (the power of each beam divided by the light splitter is reduced by half); if 30W laser is needed for cloth cutting, then the power of the laser needs to be increased from 30W to 60W after dividing the incident light into two beams by the light splitter, which increases the manufacturing cost. Utility model content

[0006] The utility model discloses a kind of light-splitting laser cutting devices for embroidery machine, it can be in without increasing the power of laser, realize using single laser simultaneously to the cloth of multiple stations on embroidery machine is cut, to reduce manufacturing cost.

[0007] The technical scheme of the utility model is:

[0008] A kind of light-splitting laser cutting device for embroidery machine, including laser and at least two cutting cloth focusing lens, further including light-splitting device, it includes:

[0009] Swing mirror that can reciprocate swing, laser emitted by laser is shot into on swing mirror, swing mirror reciprocate swing can be laser emitted by laser is reflected to each focusing lens in turn;

[0010] Driving mechanism, drive swing mirror to set frequency H reciprocate swing, to make swing mirror reflected to each focusing lens laser can simultaneously cut the cloth on embroidery machine.

[0011] The light-splitting laser cutting device for embroidery machine of the scheme is by swing mirror reciprocate swing and reflected to each focusing lens (laser is focused on cloth after passing through focusing lens and forms laser spot) one laser emitted by laser in turn, swing mirror is simultaneously set frequency H high-speed reciprocate swing, to make each focusing lens generate the intermittent laser spot of set frequency H, and laser spot has certain diameter (generally 0.1-0.5 millimeter), for example, each focusing lens generates H laser spot per second, so, when cutting the cloth on embroidery machine, it can be through the control of the moving speed of cloth, make these intermittent laser spot that focusing lens irradiates on cloth mutually bite, to realize the continuous cutting of cloth. Each focusing lens can cut the cloth of one station, and the laser of each focusing lens can simultaneously cut the cloth on embroidery machine.

[0012] On the other hand, since the light-splitting laser cutting device for embroidery machine of the scheme is by swing mirror and reflected to each focusing lens one laser emitted by laser, make each focusing lens generate the intermittent laser spot of set frequency H, so that the laser power that each focusing lens is shot into keeps consistent with the laser power that laser emits, so it can be in without increasing the power of laser, realize using single laser simultaneously to the cloth of multiple stations on embroidery machine is cut, to reduce manufacturing cost.

[0013] Preferably, the system also includes a light guide assembly, which corresponds one-to-one with the focusing lens. Each light guide assembly includes at least one reflector. The oscillating mirror oscillates back and forth, reflecting the laser emitted by the laser sequentially to the reflectors of each light guide assembly, and then to the corresponding focusing lens for focusing. In this way, the laser path can be adjusted using the reflectors of the light guide assembly, thereby adjusting the position of the focusing lens and the cutting area to adapt to different cutting needs.

[0014] Preferably, the light guide assembly also includes a protective tube arranged along the laser path within the corresponding light guide assembly. In this way, the laser light incident on the light guide assembly will be transmitted within the corresponding protective tube, effectively preventing contact between the laser and objects or personnel, thus protecting the objects and operators.

[0015] Preferably, there are two focusing lenses and two corresponding light guide components, distributed on opposite sides of the oscillating mirror. This solution can cut fabric at two stations on an embroidery machine. Distributing the two light guide components on opposite sides of the oscillating mirror not only facilitates the control of the oscillating mirror and the sequential reflection of the laser emitted by the laser to the reflectors of each light guide component, but also facilitates the arrangement of the light guide components.

[0016] Preferably, the diameter of the laser spot after focusing by the focusing lens is 0.1-0.5 mm. A larger diameter of the laser spot after focusing by the focusing lens is more conducive to the interlocking of the intermittent laser spots irradiating the fabric; however, a larger diameter also results in more dispersed laser energy, which is detrimental to cutting the fabric. Therefore, this solution sets the diameter of the laser spot after focusing by the focusing lens to 0.1-0.5 mm, thus balancing the interlocking of the intermittent laser spots irradiating the fabric and the ability of the focused laser spot to cut the fabric.

[0017] Preferably, the drive mechanism is a drive motor.

[0018] Preferably, the drive motor is fixed on the frame of the embroidery machine, and the swing mirror is directly fixed on the output shaft of the drive motor.

[0019] Preferably, the oscillating mirror is rotatably mounted on the frame of the embroidery machine via a rotating shaft, and the drive motor is mounted on the frame of the embroidery machine, with the output shaft of the drive motor connected to the rotating shaft of the oscillating mirror.

[0030] Specific embodiment one, as Figure 1 Indicated, a kind of embroidery machine with split optical laser cutting device, including laser 1, splitting device 3 and at least two cutting cloth focusing lens 2.Laser 1 is directly or indirectly arranged on the rack of embroidery machine.In the embodiment, laser 1 is installed on the rack of embroidery machine by mounting bracket.

[0031] Splitting device 3 is directly or indirectly arranged on the rack of embroidery machine.In the embodiment, splitting device 3 is installed on the rack of embroidery machine by mounting bracket.Splitting device 3 includes reciprocating swing swing mirror 3.1 and drive mechanism.The drive mechanism is used to drive swing mirror 3.1 reciprocating swing.The drive mechanism is drive motor 3.2.In the embodiment, drive motor 3.2 is galvanometer motor.Of course drive motor 3.2 can also be direct current motor or servo motor or other types of motor.

[0032] Laser emitted by laser 1 is incident on swing mirror 3.1.Swing mirror 3.1 reciprocating swing can be reflected to each focusing lens 2 in turn by laser emitted by laser 1.The drive mechanism drives swing mirror 3.1 reciprocating swing, so that laser emitted by laser 1 is reflected to each focusing lens 2 in turn.The drive mechanism drives swing mirror 3.1 reciprocating swing at set frequency H, to make swing mirror 3.1 reflected to each focusing lens 2 Laser can simultaneously cut the cloth on the embroidery machine.

[0033] In this embodiment, the embroidery machine uses a beam-splitting laser cutting device. A oscillating mirror 3.1 reciprocates, reflecting a laser beam emitted by the laser 1 sequentially to each focusing lens 2 (the laser beam is focused by the focusing lens 2 to form laser spots on the fabric). Simultaneously, the oscillating mirror 3.1 oscillates at a set frequency H at high speed, causing each focusing lens 2 to generate intermittent laser spots with a set frequency H. These laser spots have a certain diameter (generally 0.1-0.5 mm). For example, each focusing lens 2 generates H laser spots per second. Thus, when cutting the fabric on the embroidery machine, the movement speed of the fabric (which is generally slow) can be controlled, causing the intermittent laser spots focused on the fabric by the focusing lenses 2 to interlock, thereby achieving continuous cutting of the fabric. Each focusing lens 2 can cut the fabric at one workstation, and the lasers from each focusing lens 2 can simultaneously cut the fabric on the embroidery machine.

[0034] On the other hand, since the embroidery machine using the beam splitting laser cutting device in this embodiment reflects a laser beam emitted by the laser 1 sequentially to each focusing lens 2 through the swing mirror 3.1, so that each focusing lens 2 generates an intermittent laser spot with a set frequency of H, the laser power entering each focusing lens 2 each time will be consistent with the laser power emitted by the laser 1. Therefore, it is possible to cut the fabric of multiple stations on the embroidery machine simultaneously using a single laser 1 without increasing the power of the laser 1, thereby reducing the production cost.

[0035] Specific embodiment two, such as Figure 1 As shown, a beam-splitting laser cutting device for an embroidery machine includes a laser 1, a beam splitting device 3, a light guide assembly 4, and at least two focusing lenses 2 for cutting fabric. The laser 1 is directly or indirectly mounted on the frame of the embroidery machine. In this embodiment, the laser 1 is mounted on the frame of the embroidery machine via a mounting bracket.

[0036] In this embodiment, there are two focusing lenses 2. There are also two corresponding light guide assemblies 4. Each light guide assembly 4 corresponds one-to-one with a focusing lens 2. Each light guide assembly 4 includes at least one reflector 4.1.

[0037] The beam splitter 3 is mounted directly or indirectly on the frame of the embroidery machine. In this embodiment, the beam splitter 3 is mounted on the frame of the embroidery machine via a mounting bracket. The beam splitter 3 includes a reciprocating oscillating mirror 3.1 and a drive mechanism. The drive mechanism drives the oscillating mirror 3.1 to reciprocate. The drive mechanism is a drive motor 3.2. In this embodiment, the drive motor 3.2 is a galvanometer motor. Of course, the drive motor 3.2 can also be a DC motor, a servo motor, or other types of motors.

[0038] In one example, the driving motor 3.2 is fixed on the mounting bracket, and the swing mirror 3.1 is directly fixed on the output shaft of the driving motor 3.2.

[0039] In another example, the swing mirror 3.1 is arranged on the mounting bracket through a rotating shaft, and the driving motor 3.2 is fixed on the mounting bracket, and the output shaft of the driving motor 3.2 is connected with the rotating shaft of the swing mirror 3.1.

[0040] The laser emitted by the laser 1 is incident on the swing mirror 3.1. The reciprocating swing of the swing mirror 3.1 can reflect the laser emitted by the laser 1 to each focusing lens 2 in turn. Specifically, the driving mechanism drives the swing mirror 3.1 to reciprocate, so as to reflect the laser emitted by the laser 1 to the reflecting mirror 4.1 of each light guide assembly 4 in turn, and then to the corresponding focusing lens 2 through the reflecting mirror 4.1 of each light guide assembly 4 for focusing. The driving mechanism drives the swing mirror 3.1 to reciprocate at a set frequency H, so that the laser reflected by the swing mirror 3.1 to each focusing lens 2 can simultaneously cut the cloth on the embroidery machine.

[0041] The laser emitted by the laser 1 is incident on the swing mirror 3.1. The reciprocating swing of the swing mirror 3.1 can reflect the laser emitted by the laser 1 to each focusing lens 2 in turn. Specifically, the driving mechanism drives the swing mirror 3.1 to reciprocate, so as to reflect the laser emitted by the laser 1 to the reflecting mirror 4.1 of each light guide assembly 4 in turn, and then to the corresponding focusing lens 2 through the reflecting mirror 4.1 of each light guide assembly 4 for focusing. The driving mechanism drives the swing mirror 3.1 to reciprocate at a set frequency H, so that the laser reflected by the swing mirror 3.1 to each focusing lens 2 can simultaneously cut the cloth on the embroidery machine.

[0042] On the other hand, since the laser emitted by the laser 1 is reflected by the swing mirror 3.1 to each focusing lens 2 in the laser cutting device for embroidery machine of the embodiment, each focusing lens 2 generates intermittent laser spots with a set frequency H, and the laser power incident on each focusing lens 2 each time remains consistent with the laser power emitted by the laser 1, so that the two workstations of the cloth on the embroidery machine can be simultaneously cut by using a single laser 1 without increasing the power of the laser 1, thereby reducing the production cost.

[0043] Specifically, as shown in FIG. 4, the swing mirror 3.1 is arranged on the mounting bracket through a rotating shaft, and the driving motor 3.2 is fixed on the mounting bracket, and the output shaft of the driving motor 3.2 is connected with the rotating shaft of the swing mirror 3.1. Figure 1As shown, the laser 1 is located above the swing mirror 3.1, and the laser emitted by the laser 1 is incident on the swing mirror 3.1 from top to bottom. In this way, the laser and the swing mirror 3.1 are conveniently arranged on the embroidery machine.

[0044] In this embodiment, the frequency H is set to H times per second, and H is greater than or equal to 10. In this way, during the swinging of the swing mirror 3.1 at the set frequency H, each focusing lens 2 can generate at least 10 laser spots per second. When cutting the cloth on the embroidery machine, the moving speed of the cloth can be controlled to make the intermittent laser spots focused by the focusing lens 2 on the cloth bite each other, thereby realizing continuous cutting of the cloth.

[0045] In this embodiment, H is set to 80-400 times, for example, H is set to 100 or 150 or 200 or 250 or 300 times. In this way, during the swinging of the swing mirror 3.1 at the set frequency H, each focusing lens 2 can generate 80-400 laser spots per second. Although the higher the swinging frequency of the swing mirror 3.1, the more laser spots each focusing lens 2 generates per second, the more conducive to realizing continuous cutting of the cloth; but the higher the swinging frequency of the swing mirror 3.1, the higher the performance requirement of the driving mechanism, which will increase the production cost. Therefore, in this embodiment, H is set to 80-400 times, so that it can well adapt to the cutting needs of various different materials of cloth, and will not have too high performance requirements on the driving mechanism, which is conducive to controlling the production cost.

[0046] In this embodiment, during the swinging of the swing mirror 3.1 at the set frequency H, each time the swing mirror 3.1 reflects the laser emitted by the laser 1 to one of the focusing lenses 2, the swing mirror 3.1 stops for a set time T (i.e. the driving mechanism stops for a set time T), and the set time T is 1-5 milliseconds, for example, the set time T is 1 millisecond or 1.5 milliseconds or 2 milliseconds. Then, the swing mirror 3.1 continues to swing.

[0047] Further, the diameter of the laser spot focused by the focusing lens 2 is 0.1-0.5 millimeters. For example, the diameter of the laser spot focused by the focusing lens 2 is 0.3 millimeters. The larger the diameter of the laser spot focused by the focusing lens 2, the more conducive to making the intermittent laser spots focused by the focusing lens 2 on the cloth bite each other; but the larger the diameter of the laser spot focused by the focusing lens 2, the more dispersed the energy of the laser spot, which is not conducive to cutting the cloth; therefore, in this embodiment, the diameter of the laser spot focused by the focusing lens 2 is set to 0.1-0.5 millimeters, so that the ability of the intermittent laser spots focused by the focusing lens 2 on the cloth to bite each other and the ability of the focused laser spot to cut the cloth can be considered.

[0048] Further, as shown in FIG. 2, the swing mirror 3.1 is located above the focusing lens 2, and the swing mirror 3.1 is located above the laser 1. Figure 1As shown, the light guide assembly 4 also includes a protective tube 4.2, which is arranged along the laser path within the corresponding light guide assembly 4. In this way, the laser light incident on the light guide assembly 4 will be transmitted within the corresponding protective tube 4.2, effectively preventing items or personnel from coming into contact with the laser, thus protecting the items and operators.

[0049] The number of reflectors 4.1 in the light guide assembly 4 can be set according to actual needs. For example, the same light guide assembly 4 can have one, two, three or more reflectors 4.1. In actual manufacturing, the laser path can be adjusted by the reflectors 4.1 in the light guide assembly 4, thereby adjusting the position of the focusing lens 2 and the cutting part to adapt to different cutting needs.

[0050] In one implementation, such as Figure 1 As shown, the same light guide assembly 4 includes two reflectors 4.1, one of which is located above the focusing lens. The oscillating mirror 3.1 sequentially reflects the laser emitted by the laser 1 to each light guide assembly 4. After two reflections by the two reflectors 4.1 of the light guide assembly 4, the laser light enters the focusing lens from top to bottom for focusing. In this embodiment, the light guide assembly 4 has two protective tubes 4.2, one of which is located between the two reflectors 4.1, and the other is located between the oscillating mirror 3.1 and the adjacent reflector 4.1.

[0051] In another implementation, such as Figure 1 As shown, each light guide assembly 4 includes a reflector 4.1, which is located above the focusing lens. The oscillating mirror 3.1 sequentially reflects the laser emitted by the laser 1 to each light guide assembly. After being reflected by the reflector 4.1 of the light guide assembly 4, the laser light enters the focusing lens from top to bottom for focusing. In this embodiment, the protective tube 4.2 of the light guide assembly 4 is a single tube, which is located between the oscillating mirror 3.1 and the reflector 4.1.

[0052] In the third embodiment, the same light guide assembly 4 includes three reflectors 4.1 (not shown in the figure), one of which is located above the focusing lens. The oscillating mirror 3.1 sequentially reflects the laser emitted by the laser 1 to each light guide assembly 4. After three reflections by the three reflectors 4.1 of the light guide assembly 4, the laser light enters the focusing lens from top to bottom for focusing. In this embodiment, the light guide assembly 4 has three protective tubes 4.2.

[0053] In this specific embodiment, the remaining structure is the same as in specific embodiment two, except that...

[0054] like Figure 1 As shown, two light guide components 4 are distributed on opposite sides of the oscillating mirror 3.1. Correspondingly, the oscillating mirror 3.1 oscillates at an angle of 90 degrees or greater each time. The laser emitted by the laser 1 is vertically downward and enters the oscillating mirror 3.1.

[0055] In the embodiment, the angle of each swing of the swing mirror 3.1 is 90 degrees. Specifically, when the swing mirror 3.1 swings 45 degrees clockwise from the horizontal state (at this time, the swing mirror 3.1 is at a positive 45-degree angle), the swing mirror 3.1 reflects the laser emitted by the laser 1 to one of the focusing lenses 2; when the swing mirror 3.1 swings 45 degrees counterclockwise from the horizontal state (at this time, the swing mirror 3.1 is at a negative 45-degree angle), the swing mirror 3.1 reflects the laser emitted by the laser 1 to the other focusing lens 2.

[0056] In specific operation, the driving mechanism drives the swing mirror 3.1 to swing at a set frequency H. During this process, when the swing mirror 3.1 rotates to a positive 45-degree angle and reflects the laser emitted by the laser 1 to one of the focusing lenses 2, the swing mirror 3.1 stops for a set time T, which is 1-5 milliseconds, for example, 1 millisecond, 1.5 milliseconds, or 2 milliseconds.

[0057] When the swing mirror 3.1 rotates to a negative 45-degree angle and reflects the laser emitted by the laser 1 to the other focusing lens 2, the swing mirror 3.1 stops for a set time T, which is 1-5 milliseconds, for example, 1 millisecond, 1.5 milliseconds, or 2 milliseconds.

[0058] In a specific embodiment four, the rest of the structure of the embodiment is referred to the specific embodiment two, and the difference is that,

[0059] In the embodiment, the focusing lenses 2 are three or four (not shown in the figure). The light guide assemblies 4 correspondingly are three or four (not shown in the figure). Each light guide assembly 4 corresponds to one focusing lens 2. In the working process of the embroidery machine light splitting type laser cutting device, each focusing lens 2 can cut the cloth of one work position, and the lasers of the focusing lenses 2 can simultaneously cut the cloth on the embroidery machine, thereby realizing cutting the cloth of three or four work positions on the embroidery machine simultaneously by using a single laser 1.

[0060] The above is only a preferred embodiment of the present application, and does not limit the present application in any way. Any simple modification, change, and equivalent transformation of the above embodiment according to the technical essence of the present application are still within the protection scope of the technical solution of the present application.
