Description

Technical Field

[0001] The present invention relates to the technical field of laser cutters, and more specifically, to a spectroscopic device and a laser cutter. Background Art

[0002] An embroidery machine is a machine used to embroider textiles. It can automatically complete complex embroidery patterns through computer control or mechanical drive, greatly improving the efficiency and accuracy of embroidery.

[0003] Laser embroidery machine is a special embroidery machine with a laser system installed on it. It perfectly combines computer embroidery with high-speed laser cutting and laser engraving. The basic principle of laser embroidery machine is to use the high-energy laser beam to cut the fabric in different ways according to the predetermined design through beam projection. It is mainly composed of laser, laser beam control motion system and drawing system to control the embroidery machine to perform automatic embroidery engraving.

[0004] At present, when using a laser embroidery machine to cut patterns on the surface of fabrics, a traditional laser embroidery machine usually has multiple laser cutting stations arranged on the beam, that is, multiple embroidery machine heads are arranged. At the same time, a laser emitting unit is independently designed on each embroidery machine head. The laser is emitted to the embroidery machine head through the laser emitting unit, and the laser is output on the fabric surface through the embroidery machine head to achieve cutting of the pattern on the fabric surface. This results in the number of laser emitters needing to correspond one-to-one with the embroidery machine heads. The arrangement of multiple laser emitters will not only increase the procurement cost, but also increase the burden of subsequent maintenance and overhaul, which is very inconvenient. In view of this, we propose a spectroscopic device and a laser cutter. Summary of the invention

[0005] The purpose of the present invention is to provide a spectroscopic device and a laser cutter to solve the technical problem that the existing laser embroidery machine needs to be equipped with multiple laser emitting units, which leads to increased procurement costs and increased burden of subsequent maintenance and repair.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a spectroscopic device, comprising a laser delivery component;

[0007] The laser delivery assembly comprises a light splitting assembly with a light guide arm and a light delivery arm detachably mounted at both ends;

[0008] The spectrometer assembly includes a bottom plate with pipe clamps formed at both ends of the upper end surface, a spectrometer seat is formed on one side of one of the pipe clamps, a flat plate spectrometer is detachably installed inside the spectrometer seat, a spectrometer film is attached to one side of the flat plate spectrometer, and an anti-reflection film is attached to the other side of the flat plate spectrometer, a spectrometer is detachably installed on one side of the spectrometer seat, a light output arm is detachably installed on one side of the spectrometer seat, and a delivery pipe is constructed and installed between a side of the spectrometer away from the spectrometer seat and the pipe clamp, and a convex lens for focusing ghost images after laser spectrometry is detachably installed inside the light output arm.

[0009] The present invention designs a spectroscopic component. After the laser enters the spectrometer through a delivery tube, it is spectroscopically processed by a spectroscopic film on the surface of a flat spectroscope. When the laser contacts the spectroscopic film, a part of the laser directly penetrates the spectroscopic film, and the other part of the laser reacts with the spectroscopic film to generate reflection, thereby dividing the linear output laser into two beams, and the two beams are output separately, which is beneficial to using a single laser beam for double-head cutting processing and is beneficial to reducing the procurement cost of the laser transmitter and the maintenance and repair burden.

[0010] Preferably, the ends of the light-transmitting arm and the light-guiding arm facing each other can be detachably installed in the pipe clamp, and the end of the light-transmitting arm away from the pipe clamp is detachably connected to refractor one, and the end of the light-guiding arm away from the pipe clamp is detachably connected to refractor three.

[0011] Preferably, a beam splitter arm is detachably mounted on one side of the refractor three and inside the light output arm, the end of the beam splitter arm is detachably connected to the refractor two, and a laser cutting head is detachably mounted on the bottom of the refractor two.

[0012] Preferably, an L-shaped plate is detachably mounted on the top of the second refractor, and a reflecting mirror for reflecting laser light is detachably mounted inside the second refractor, the third refractor and the first refractor.

[0013] A laser cutter includes an embroidery machine beam;

[0014] A laser assembly is detachably mounted on the bottom of one side of the embroidery machine beam;

[0015] The laser assembly includes a laser emitting component detachably mounted on the bottom of one side of the embroidery machine beam and a laser conveying component detachably connected to the laser emitting component;

[0016] The laser emitting component comprises a laser emitter with an L-shaped fixing plate detachably mounted on the upper end surface, the L-shaped fixing plate is detachably connected to the embroidery machine beam, and one end of the laser emitter is formed with a connecting tube for outputting laser.

[0017] Preferably, one end of the connecting tube away from the laser emitter is detachably connected to the refractor, and the L-shaped plate is detachably mounted on one side of the embroidery machine beam.

[0018] Preferably, an embroidery machine head is equidistantly arranged on a side of the embroidery machine beam away from the laser emitting component, and the embroidery machine head is detachably mounted on the embroidery machine beam.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention designs a spectroscopic component. After the laser enters the spectrometer through a delivery tube, it is spectroscopically processed by a spectroscopic film on the surface of a flat spectroscope. When the laser contacts the spectroscopic film, a part of the laser directly penetrates the spectroscopic film, and the other part of the laser reacts with the spectroscopic film to generate reflection, thereby dividing the linear output laser into two beams, and the two beams are output separately, which is conducive to using a single laser beam for double-head cutting processing, and is conducive to reducing the purchase cost and maintenance burden of the laser transmitter, and solves the problem that the existing laser embroidery machine needs to be arranged with multiple laser emission units, resulting in increased purchase costs and increased later maintenance burdens.

[0021] 2. The present invention also designs a convex lens. Since the laser will produce a ghost image in a direction parallel to the reflected laser when passing through the splitting film for splitting processing, the ghost image can be focused by designing a convex lens, thereby achieving the purpose of focusing, so that the ghost image and the reflected laser are output overlappingly, avoiding the adverse effect of the ghost image on the pattern cutting process on the fabric surface.

[0031] like Figure 1-Figure 7 As shown, the present invention relates to a spectroscopic device, including a laser delivery component 5;

[0032] The laser delivery assembly 5 includes a light splitting assembly 6 with a light guide arm 506 and a light delivery arm 502 detachably mounted at both ends;

[0034] Since the laser will generate a ghost image in a direction parallel to the reflected laser when passing through the splitter film for splitting, the ghost image can be focused by designing the convex lens 606, thereby achieving the purpose of focusing, so that the ghost image and the reflected laser are output overlappingly.

[0035] After the laser emitted by the same laser emitter 401 is split into two, the two laser beams can simultaneously perform pattern cutting work on the surface of the fabric, and the power intensity of the two laser beams after the splitting is equal.

[0036] In an embodiment of the present invention, the ends of the light-transmitting arm 502 and the light-guiding arm 506 facing each other can be removably installed in the pipe clamp 602, and the end of the light-transmitting arm 502 away from the pipe clamp 602 can be removably connected to the refractor 1 501, and the end of the light-guiding arm 506 away from the pipe clamp 602 can be removably connected to the refractor 3 507.

[0037] By designing the refractor 1 501, the laser light emitted by the laser transmitter 401 can be steered, and by designing the refractor 3 507, the split laser light can be steered.

[0038] In the embodiment of the present invention, a splitter arm 503 is detachably mounted on one side of the refractor three 507 and inside the light output arm 605, the end of the splitter arm 503 is detachably connected to the refractor two 504, and a laser cutting head 505 is detachably mounted on the bottom of the refractor two 504.

[0039] By designing the second refractor 504 , the laser light can be steered so as to be output through the laser cutting head 505 .

[0040] In the embodiment of the present invention, an L-shaped plate is detachably mounted on the top of the second refractor 504, and a reflecting mirror for reflecting laser light is detachably mounted inside the second refractor 504, the third refractor 507 and the first refractor 501.

[0041] A laser cutter comprises an embroidery machine beam 1;

[0042] A laser assembly 3 is detachably mounted on the bottom of one side of the embroidery machine beam 1;

[0043] The laser assembly 3 includes a laser emitting component 4 detachably mounted on the bottom of one side of the embroidery machine beam 1 and a laser conveying component 5 detachably connected to the laser emitting component 4;

[0044] The laser emitting component 4 includes a laser emitter 401 with an L-shaped fixing plate 402 detachably mounted on the upper end surface. The L-shaped fixing plate 402 is detachably connected to the embroidery machine beam 1 by means of bolts. One end of the laser emitter 401 is formed with a connecting tube 403 for outputting laser.

[0046] Working principle: This embodiment provides a spectrometer and a laser cutter. When in use, the laser is first emitted by the laser emitter 401, and the laser is output through the connecting tube 403. The laser is reflected when it contacts the reflector inside the refractor 501, so that the laser is transported through the light sending arm 502. After the laser enters the spectrometer 604 through the transport tube 603, it is spectrometered by the spectrometer film on the surface of the flat spectrometer 608. When the laser contacts the spectrometer film, a part of the laser directly penetrates the spectrometer film, and the other part of the laser reacts with the spectrometer film to generate reflection. The penetrated laser continues to be transported along the light guide arm 506, and is reflected when it contacts the reflector inside the refractor 507, so that the penetrated laser and the reflected laser are both transported through the spectrometer arm 503, and output to the fabric surface through the laser cutting head 505, thereby realizing the cutting processing of the fabric surface pattern.
