Description

Technical Field

[0001] This utility model relates to the field of laser machine equipment technology, specifically a dual-head laser machine. Background Technology

[0002] A laser cutting machine is a processing device that uses a high-energy laser beam to guide a mirror through a reflector to a galvanometer, which then deflects the beam at high speed to cut, mark, or weld on a target surface. To improve processing efficiency and expand the processing range, existing technologies often employ a dual-head laser cutting machine structure, where two sets of galvanometers are mounted on the same frame to allow for simultaneous or alternating processing operations at different stations. Traditional dual-head laser cutting machines typically equip each set of galvanometers with an independent laser, ensuring that both the first and second galvanometers have independent light source inputs and thus guaranteeing the processing independence of the two sets of galvanometers.

[0003] However, while this structure achieves the dual-head function, it also has obvious shortcomings: First, a second laser must be added, which significantly increases the overall cost of the equipment; second, the simultaneous installation of two lasers in the rack increases the size of the rack and the complexity of the internal structure, which is not conducive to the miniaturization of the equipment and its later maintenance; third, the energy consumption is high when multiple lasers are running at the same time, and the optical path calibration process is complicated, which increases the difficulty of equipment debugging and use. Utility Model Content

[0004] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.

[0005] To achieve the above objectives, this application provides the following technical solution: A dual-head laser machine includes a laser, a frame, a first reflector, a third reflector, a first galvanometer, a second galvanometer, and a movable base; The laser is disposed on one side outside the frame, and the first galvanometer and the second galvanometer are respectively disposed on the other side outside the frame; The first reflector is disposed on one side inside the frame, and the third reflector is mounted on the movable base and is movable on the frame located on the side of the first reflector.

[0006] Preferably, it further includes a second reflector and a fourth reflector; the first reflector is disposed on one side inside the frame, the second reflector is disposed on the other side inside the frame, and the third and fourth reflectors are mounted on the movable base and movably disposed on the frame between the first and second reflectors.

[0007] Preferably, the frame has a rectangular structure.

[0008] Preferably, the laser, the frame, the first galvanometer, and the second galvanometer are all horizontally arranged.

[0009] Preferably, the movable seat is a slide.

[0010] Preferably, the third reflector is mounted on the movable base and moved by a drive device to the frame located to the side of the first reflector.

[0011] Preferably, the third and fourth reflectors are mounted on the movable base and moved between the first and second reflectors on the frame via a drive device.

[0012] Preferably, the driving device is a cylinder or an electric motor.

[0013] In summary, the technical effects and advantages of this utility model are as follows: When using this solution, the laser is positioned on one side outside the frame and activated. The laser beam emitted by the laser enters the frame and is directed towards the third reflector mounted on a movable base. The movable base moves on the frame to control the switching between the third and first reflectors, thereby determining the direction of the optical path. When the laser beam enters the third reflector, it can be directly guided to the first galvanometer, which then applies the laser beam to the corresponding target. When a switch in the optical path is required, the third reflector moves away from the corresponding area, allowing the laser beam to enter the first reflector and be directly guided to the second galvanometer, which then applies the laser beam to another target. This solution, by setting a third reflector on the movable base, and allowing the third reflector to move and switch on the frame to become the optical path of the first reflector, enables the laser output to switch freely between the two optical paths, corresponding to the independent processing of the first and second galvanometers respectively. This achieves the effect of a dual-head setup with only one laser, equivalent to having two lasers simultaneously configured. This effectively solves the problems of increased cost, larger size, and increased energy consumption caused by the need to add a second laser to drive the two galvanometers in traditional technologies.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, please refer to Figures 1-2 : A dual-head laser machine includes a laser 1, a frame 2, a first reflector 3, a third reflector 5, a first galvanometer 7, a second galvanometer 8, and a movable base 9. The laser 1 is disposed on one side outside the frame 2, and the first galvanometer 7 and the second galvanometer 8 are respectively disposed on the other side outside the frame 2. The first reflector 3 is disposed on one side inside the frame 2, and the third reflector 5 is mounted on the movable base 9 and is movably disposed on the frame 2 on the side of the first reflector 3.

[0022] Working Principle: In this design, laser 1 is positioned on one side outside the frame 2 and activated. The laser emitted by laser 1 enters the frame 2 and is directed towards the third reflector 5 mounted on the movable base 9. The movable base 9 moves on the frame 2 to control the position switching of the third reflector 5, thus determining the direction of two independent optical paths. When the laser enters the third reflector 5, the beam can be directly guided to the first galvanometer 7, which then directs the laser onto the corresponding target. When a switch is needed, the third reflector 5 moves away from the corresponding area, allowing the laser to enter the first reflector 3. The beam can then be directly guided to the second galvanometer 8, which directs the laser onto the target. The galvanometer 8 directs the laser to another target. This solution uses a third reflector 5 on a movable base, which can be moved and switched on the frame 2 to become the optical path of the first reflector 3. This allows the output of the laser 1 to switch freely between the two optical paths, corresponding to the independent processing of the first galvanometer 7 and the second galvanometer 8 respectively. Thus, with only one laser 1, the effect of a dual-head machine is achieved, which is equivalent to having two lasers 1 configured simultaneously. This effectively solves the problems of increased cost, increased size, and increased energy consumption caused by the need to add a second laser to drive the two galvanometers in traditional technology.

[0023] Preferably, the frame is a rectangular structure. The rectangular frame 2 consists of four straight sides and four mutually perpendicular corners, with a clearly defined long and short side in its overall geometry, allowing the frame 2 to form a regular force distribution path in both the longitudinal and transverse directions. In the dual-head laser machine, the laser 1 is located on one side outside the frame 2, the first reflector 3 is located on one side inside the frame 2, and the third reflector 5 is mounted on the movable base 9 and moves on the frame 2. The rectangular structure provides parallel and orthogonal mounting reference surfaces for the aforementioned multiple optical elements, ensuring that the optical axis direction of each reflector maintains a strict parallel or perpendicular relationship with the frame boundary. This guarantees that the incident angle and reflection angle of the laser beam are stable during the reflection and transmission process, avoiding optical path deviations caused by irregular support surfaces or offset mounting angles. Meanwhile, the rectangular structure provides excellent spatial separation, forming symmetrical and equidistant installation areas within it. This facilitates the fixing of the first reflector 3 to one side of the frame 2, ensuring that the two transmission paths maintain the same geometric symmetry during optical path switching. This helps the first galvanometer 7 and the second galvanometer 8 obtain consistent beam incident conditions when receiving light. Furthermore, the rectangular frame has right-angled corners, allowing for a tight fit with external processing equipment or fixed support bases. This improves the overall installation stability and vibration resistance of the equipment, preventing optical path drift caused by frame deformation during long-term operation of the laser 1 and reflectors.

[0024] Preferably, the laser, the frame, the first galvanometer, and the second galvanometer are all horizontally positioned. Using the horizontal positioning of the frame 2 as a unified installation reference, the emission centerline of the laser 1, the entrance boundary of the first galvanometer, and the second galvanometer 8 are all located in the same horizontal reference plane. After the laser beam exits the laser 1, it propagates within this horizontal reference plane to the first reflecting mirror 3 located on one side of the frame 2 or the third reflecting mirror 5 located on one side of the frame 2 (directly introduced by the third reflecting mirror 5 on the movable base 9). This ensures that the two paths, "laser 1 → third reflecting mirror 5 → first galvanometer 7" and "laser 1 → first reflecting mirror 3 → second galvanometer 8," are at the same height in their vertical components and coplanar in the horizontal reference plane. The horizontal positioning ensures that the direction of gravity is aligned with the horizontal reference plane. With the reference plane orthogonal, the deflection caused by the weight of the frame 2 and the optical components is mainly projected in the vertical direction, without changing the geometric relationship of the beam in the reference plane. The movement of the moving seat 9 on the frame 2 only changes the horizontal path selection of the beam in the reference plane without introducing a height deviation, thereby enabling the first galvanometer 7 and the second galvanometer 8 to obtain the same incident height and incident angle range. The above-mentioned coplanar, equal height and parallel relationship is formed by the simultaneous horizontal setting of the laser 1, the frame 2, the first galvanometer 7 and the second galvanometer 8, so that the optical path switching does not involve vertical direction compensation. When the beam switches between the two galvanometers, it maintains the same geometric boundary conditions and reflection sequence, structurally ensuring the optical alignment stability and path consistency of the dual heads under the same horizontal reference.

[0025] Preferably, the movable base is a slide. The movable part carrying the third reflector 5 is defined as a slide that moves linearly back and forth along a preset direction on the frame 2, so that the third reflector 5 has only one degree of linear movement in the region on the side of the first reflector 3, avoiding in-plane rotation and non-axial offset, and ensuring that the incident position and incident angle of any reflector remain consistent when entering the laser's incident path; when the slide moves to the position where the laser enters the third reflector 5 under the action of the driving device, a continuous optical path of "laser 1 → third reflector 5 → first galvanometer 7" is formed; when the slide moves to the position where the laser enters the first reflector 3, the third reflector 5... The reflector 5 leaves the incident path, forming a continuous optical path of "laser 1 → first reflector 3 → second galvanometer 8". By switching positions in a sliding manner, the spatial relationship between the two reflectors and the frame 2 is kept consistent in each switch, and the incident height and coplanar relationship are stable, reducing the angle error and position deviation during optical path switching. This ensures that under the conditions of fixed laser 1, fixed first reflector 3, and fixed first and second galvanometers 7 and 8, stable mutually exclusive selection and repeated positioning of the two optical paths are achieved, meeting the optical alignment requirements of the dual-head laser machine for independent processing of the two galvanometers under a single light source.

[0026] Preferably, the third reflector is mounted on the movable base and moved on the frame to the side of the first reflector by a driving device (not shown). The driving device moves the movable base 9 relative to the frame 2 on the side of the first reflector 3, positioning the third reflector 5 at the incident path position after the laser 1 enters the frame 2. When the third reflector 5 is positioned at the incident path position, the laser is reflected sequentially by the third reflector 5 to the first galvanometer 7. When the first reflector 3 is positioned at the incident path position, the first reflector 3 directly transmits the laser to the second galvanometer 8. Since the third reflector 5 and the first reflector 3 are at the same horizontal position, the laser... The switching between the two transmission links "1→3rd reflector 5→1st galvanometer 7" and "laser 1→1st reflector 3→2nd galvanometer 8" is completed by a single movement of the moving base 9 without changing the positions of the laser 1, the first reflector 3, the first galvanometer 7 and the second galvanometer 8. Structurally, this forms a distribution mechanism with the moving base as the switching execution unit and the third reflector 5 as the optical path selection surface, so that the single output of the laser 1 is guided within the frame to either the first galvanometer 7 or the second galvanometer 8 to correspond to the two optical paths of the dual-head unit.

[0027] Preferably, the driving device is a cylinder or a motor. The driving device is connected to the movable seat 9 and drives the movable seat 9 to reciprocate linearly on the frame 2, thereby moving the third reflector 5 mounted on the movable seat 9 within the area on the side of the first reflector 3. When the driving device is a cylinder, compressed gas acts on the piston rod to generate a linear push-pull force, directly driving the movable seat 9 to move along the guide rail, realizing the rapid switching of the third reflector 5 in the incident light path. When the driving device is a motor, the rotational motion of the motor is converted into the linear displacement of the movable seat 9 through a lead screw or gear-rack transmission mechanism, thereby realizing the precise positioning and repeated switching of the third reflector 5. The cylinder drive has the characteristics of fast response speed, direct action and suitability for high-frequency switching, while the motor drive has the characteristics of precise position control, stable operation and suitability for long-term work. Both can ensure that the moving seat 9 drives the third reflector 5 to maintain a stable linear motion trajectory when switching optical paths, avoiding the sway or angle error of the reflector during the switching process. This ensures that the laser beam always enters the first reflector 3 with the correct incident angle before and after switching, realizing the stable switching of the two optical paths "laser 1 → third reflector 5 → first galvanometer 7" and "laser 1 → first reflector 3 → second galvanometer 8", ensuring that the dual-head laser machine can complete the independent processing function of the dual galvanometers under the condition of single laser output.

[0028] Example 2, please refer to Figures 3-4 : A dual-head laser machine includes a laser 1, a frame 2, a first reflector 3, a second reflector 4, a third reflector 5, a fourth reflector 6, a first galvanometer 7, a second galvanometer 8, and a movable base 9. The laser 1 is disposed on one side outside the frame 2, and the first galvanometer 7 and the second galvanometer 8 are respectively disposed on the other side outside the frame 2; The first reflector 3 is disposed on one side inside the frame 2, the second reflector 4 is disposed on the other side inside the frame 2, and the third reflector 5 and the fourth reflector 6 are mounted on the movable seat 9 and are movably disposed on the frame 2 between the first reflector 3 and the second reflector 4.

[0029] Working principle: When using this scheme, laser 1 is set on one side outside the frame 2 and activated. The laser emitted by laser 1 enters the frame 2 and is directed towards the third reflector 5 or the fourth reflector 6 mounted on the movable base 9. The movable base 9 moves on the frame 2 to control the switching between the third reflector 5 and the fourth reflector 6, thereby determining the direction of the optical path. When the laser enters the third reflector 5, the beam passes sequentially through the third reflector 5 and the first reflector 3 on one side inside the frame 2, and is guided to the first galvanometer 7 outside the frame 2. The first galvanometer 7 then directs the laser beam to the corresponding target. When the laser enters the fourth reflector 6, the beam passes sequentially through the fourth reflector 6 and the second reflector 4 on the other side inside the frame 2, and is guided to the second galvanometer 8 outside the frame 2. The laser is directed to another target by the second galvanometer 8. This solution sets a third reflector 5 and a fourth reflector 6 on the movable base 9 and moves them on the frame 2 to switch between the two optical paths, so that the output of the laser 1 can be freely switched between the two optical paths, corresponding to the independent processing of the first galvanometer 7 and the second galvanometer 8 respectively. Thus, with only one laser 1, it achieves the effect of a dual-head machine with two lasers 1 configured at the same time. This effectively solves the problems of increased cost, increased size and increased energy consumption caused by the need to add a second laser to drive the two galvanometers in the traditional technology. In this embodiment 2, the overall arrangement of this solution is in the shape of "I", which greatly saves the space occupied compared to the "L" shape of the arrangement in embodiment 1.

[0030] Preferably, the frame 2 is a rectangular structure. The rectangular frame 2 consists of four straight sides and four mutually perpendicular corners, with a clearly defined long and short side, allowing the frame 2 to form a regular force distribution path in both the longitudinal and transverse directions. In the dual-head laser machine, the laser 1 is located on one side outside the frame 2, the first reflector 3 and the second reflector 4 are respectively located on both sides inside the frame 2, and the third reflector 5 and the fourth reflector 6 are mounted on the movable base 9 and move on the frame 2. The rectangular structure provides parallel and orthogonal mounting reference surfaces for the aforementioned optical elements, ensuring that the optical axis direction of each reflector maintains a strict parallel or perpendicular relationship with the frame boundary. This guarantees that the incident angle and reflection angle of the laser beam are stable during reflection and transmission, avoiding optical path deviations caused by irregular support surfaces or offset mounting angles. Meanwhile, the rectangular structure provides excellent spatial separation, forming symmetrical and equidistant installation areas within it. This facilitates the fixing of the first reflector 3 and the second reflector 4 to opposite sides within the frame 2, ensuring that the two transmission paths maintain the same geometric symmetry during optical path switching. This helps the first galvanometer 7 and the second galvanometer 8 obtain consistent beam incident conditions when receiving light. Furthermore, the rectangular frame has right-angled corners, allowing for a tight fit with external processing equipment or fixed support bases. This improves the overall installation stability and vibration resistance of the equipment, preventing optical path drift caused by frame deformation during long-term operation of the laser 1 and reflectors.

[0031] Preferably, the laser 1, the frame 2, the first galvanometer 7, and the second galvanometer 8 are all horizontally arranged. Using the horizontal arrangement of the frame 2 as a unified installation reference, the emission centerline of the laser 1, the boundary surfaces of the first galvanometer 7 and the second galvanometer 8 are all located in the same horizontal reference plane. After the laser beam exits the laser 1, it propagates within this horizontal reference plane to the first reflecting mirror 3 on one side of the frame 2 or the second reflecting mirror 4 on the other side of the frame 2 (introduced by the third reflecting mirror 5 or the fourth reflecting mirror 6 on the moving base 9). This ensures that the two paths, "laser 1 → third reflecting mirror 5 → first reflecting mirror 3 → first galvanometer 7" and "laser 1 → fourth reflecting mirror 6 → second reflecting mirror 4 → second galvanometer 8," are at the same height in their vertical components and coplanar in the horizontal reference plane. The horizontal setting ensures that the direction of gravity is orthogonal to the reference plane. The deflection caused by the weight of the frame 2 and the optical components is mainly projected in the vertical direction, without changing the geometric relationship of the beam in the reference plane. The movement of the moving seat 9 on the frame 2 only changes the horizontal path selection of the beam in the reference plane without introducing a height deviation, thereby enabling the first galvanometer 7 and the second galvanometer 8 to obtain the same incident height and incident angle range. The above-mentioned coplanar, equal height and parallel relationship is formed by the simultaneous horizontal setting of the laser 1, the frame 2, the first galvanometer 7 and the second galvanometer 8, so that the optical path switching does not involve vertical direction compensation. When the beam switches between the two galvanometers, it maintains the same geometric boundary conditions and reflection sequence, structurally ensuring the optical alignment stability and path consistency of the dual heads under the same horizontal reference.

[0032] Preferably, the third reflector 5 and the fourth reflector 6 are mounted on the movable base 9 and moved between the first reflector 5 and the second reflector 6 on the frame 2 via a driving device (not shown). The driving device moves the movable base 9 relative to the frame 2 between the first reflector 3 and the second reflector 4, positioning either the third reflector 5 or the fourth reflector 6 at the incident path position after the laser 1 enters the frame 2, while the other moves away from that incident path position. Thus, the position of the movable base 9 determines the mirror entity of the first reflection and accordingly determines the subsequent optical path. When the third reflector 5 is positioned at the incident path position, the laser is reflected sequentially by the third reflector 5 to the first reflector 3 located on one side inside the frame 2, and then the first reflector 3 transmits the light to the first galvanometer 7. When the fourth reflector 6 is positioned at the incident path position, the laser is reflected sequentially by the fourth reflector 6 to the second reflector 4 located on the other side inside the frame 2, and then the second reflector 4 transmits the light to the second reflector 7. The laser beam is directed to the second galvanometer 8. Since the third reflector 5 and the fourth reflector 6 mutually exclude each other from entering the incident path through the movement of the same moving seat 9 on the frame 2, the switching between the two transmission links of "laser 1 → third reflector 5 → first reflector 3 → first galvanometer 7" and "laser 1 → fourth reflector 6 → second reflector 4 → second galvanometer 8" is completed by a single movement of the moving seat 9 without changing the setting positions of the laser 1, the first reflector 3, the second reflector 4, the first galvanometer 7 and the second galvanometer 8. Structurally, this forms a distribution mechanism with the moving seat as the switching execution unit and the third reflector 5 and the fourth reflector 6 as the optical path selection surfaces, so that the single output of the laser 1 is guided within the frame to either the first galvanometer 7 or the second galvanometer 8 to correspond to the two optical paths of the dual-head laser.

[0033] Preferably, the driving device is a cylinder or a motor. The driving device is connected to the movable seat 9 and drives the movable seat 9 to reciprocate linearly on the frame 2, thereby moving the third reflector 5 and the fourth reflector 6 mounted on the movable seat 9 within the area between the first reflector 3 and the second reflector 4. When the driving device is a cylinder, compressed gas acts on the piston rod to generate a linear push-pull force, directly driving the movable seat 9 to move along the guide rail, realizing the rapid switching of the third reflector 5 and the fourth reflector 6 in the incident light path. When the driving device is a motor, the rotational motion of the motor is converted into the linear displacement of the movable seat 9 through a lead screw or gear-rack transmission mechanism, thereby realizing the precise positioning and repeated switching of the third reflector 5 and the fourth reflector 6. The cylinder drive has the characteristics of fast response speed, direct action, and suitability for high-frequency switching, while the motor drive has the characteristics of precise position control, stable operation, and suitability for long-term work. Both can ensure that the moving seat 9 drives the third reflector 5 and the fourth reflector 6 to maintain a stable linear motion trajectory when switching optical paths, avoiding the swaying or angle error of the reflectors during the switching process. This ensures that the laser beam always enters the first reflector 3 or the second reflector 4 at the correct incident angle before and after switching, realizing the stable switching of the two optical paths "laser 1 → third reflector 5 → first reflector 3 → first galvanometer 7" and "laser 1 → fourth reflector 6 → second reflector 4 → second galvanometer 8". This ensures that the dual-head laser machine can complete the independent processing function of the two galvanometers under the condition of a single laser output.

[0034] Preferably, the movable seat 9 is a slide. The movable part carrying the third reflector 5 and the fourth reflector 6 is defined as a slide that moves linearly back and forth along a preset direction on the frame 2. This ensures that the third reflector 5 and the fourth reflector 6 have only one degree of linear movement within the region between the first reflector 3 and the second reflector 4, avoiding in-plane rotation and non-axial offset, and ensuring that the incident position and incident angle of any reflector remain consistent when entering the laser's incident path. When the slide moves to the position where the laser enters the third reflector 5 under the action of the driving device, the fourth reflector 6 leaves the incident path, forming a continuous optical path of "laser 1 → third reflector 5 → first reflector 3 → first galvanometer 7". When the position of the fourth reflector 6 is described, the third reflector 5 leaves the incident path, forming a continuous optical path of "laser 1 → fourth reflector 6 → second reflector 4 → second galvanometer 8". By switching positions in a sliding manner, the spatial relationship between the two reflectors and the frame 2 is kept consistent in each switch, and the incident height and coplanar relationship are stable, reducing the angle error and position deviation during optical path switching. This ensures that under the conditions of the fixed setting of the laser 1, the fixed setting of the first reflector 3 and the second reflector 4, and the fixed setting of the first galvanometer 7 and the second galvanometer 8, the stable mutually exclusive selection and repeated positioning of the two optical paths are achieved, meeting the optical alignment requirements of the dual-head laser machine for independent processing of the two galvanometers under a single light source.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
