Description

Technical Field

[0001] The invention belongs to the technical field of laser cutters, and in particular relates to an automatic adjustment laser beam splitting device. Background Art

[0002] With the demand of production development, the market has higher and higher requirements for the speed and precision of material cutting, so nowadays laser cutting technology has been introduced in material cutting; the use of laser cutting technology to cut materials has the advantages of smooth cut surface and fast cutting, so this technology has been rapidly widely used and many laser cutting machines have been invented accordingly; however, in actual production operations, due to the large width of the cutting material and the large number of parts that need to be cut, the cutting efficiency of the laser cutter with a simple structure composed of a single laser exciter is insufficient, and if the number of laser exciters is increased, the cost of the laser cutter will be too high; in the existing technology, for example, a "rotatable adjustable laser cutter for embroidery machines" disclosed in Chinese patent documents, with a publication number of CN218426248U, adds a rotatable and adjustable first reflector and a number of secondary reflectors to the laser transmission device, so that only one laser exciter is needed to realize the cutting operation of multiple stations, but its disadvantage is that each station cannot operate at the same time, and the cutting efficiency cannot be effectively improved. Summary of the invention

[0003] The object of the present invention is to provide an automatically adjustable laser spectrometer, which can realize the simultaneous operation of multiple workstations with only one laser, thereby improving the efficiency of laser cutting and reducing the cost.

[0004] To achieve the above object, the present invention provides the following technical solution: an automatic adjustment laser spectrometer, comprising:

[0005] A secondary total reflection mirror that reflects the laser beam to the output optical path;

[0006] A primary full-reflection mirror for reflecting the laser beam generated by the laser exciter to adjust the laser transmission direction;

[0007] A beam splitter for splitting a laser beam generated by a laser exciter into two laser beams;

[0008] It is equipped with two kinds of lenses, the main full-reflection mirror and the beam splitter, and the rotation axes used by the two lenses can be rotated to switch respectively;

[0009] The laser beam splitter can split a laser beam generated by a laser exciter into multiple light paths and switch the required number of light paths, thereby realizing simultaneous processing of multiple workstations.

[0010] As a preferred technical solution of the present invention, two cutting modes of the laser cutting machine are implemented, namely:

[0011] Mode 1 for cutting thick materials;

[0012] Mode 2 for cutting thin materials.

[0013] As a preferred technical solution of the present invention, the operating principle of mode one is as follows: first, the rotating shaft is rotated to drive the main-stage total reflection mirror to rotate; then, the laser beam generated by the laser exciter is incident on the surface of the main-stage total reflection mirror, the main-stage total reflection mirror reflects the laser beam to the secondary total reflection mirror, and the secondary total reflection mirror then reflects the laser beam to the output optical path.

[0014] As a preferred technical solution of the present invention, the rotating shaft is rotated to drive the main-stage total reflection mirror to rotate, so that the main-stage total reflection mirror rotates to the same side and below the laser exciter.

[0015] As a preferred technical solution of the present invention, the theoretical power of the primary total reflection mirror in reflecting the laser beam to the secondary total reflection mirror is 100%.

[0016] As a preferred technical solution of the present invention, the operating principle of mode 2 is as follows: first, the rotating shaft is rotated to drive the beam splitter to rotate; then, the laser beam generated by the laser exciter is incident on the surface of the beam splitter, and the beam splitter splits the laser beam into two beams, one beam is directly output through the beam splitter, and the other beam is reflected by the beam splitter to the surface of the secondary total reflection mirror, and the secondary total reflection mirror then reflects the laser beam to the output optical path.

[0017] As a preferred technical solution of the present invention, the rotating shaft is rotated to drive the beam splitter to rotate so that the beam splitter rotates to the same side and below the laser exciter.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Only one laser can realize the simultaneous operation of multiple stations, which improves the efficiency of laser cutting and reduces the cost;

[0020] The adjustable beam splitter enables the laser exciter to output full power, meeting the needs of cutting thicker materials;

[0021] The adjustable beam splitter enables the laser cutter to operate at multiple stations or cut thicker materials at a single station, which has high flexibility and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS
