Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of optical path mechanism of laser head, and more specifically, it relates to an optical path mechanism of laser head and laser processing equipment. Background Technology
[0002] Multi-axis laser heads typically incorporate a rotating structure. The laser head's output port can rotate under the action of this structure to adjust its direction, allowing the laser emitted from the port to process different parts of the workpiece. During rotation, to ensure that the laser beam accurately exits from the output port, a reflector structure is usually installed within the laser head's optical path to adjust the direction of light propagation. However, the reflector structure currently installed within the optical path of laser heads has relatively low precision in adjusting the direction of light propagation. Utility Model Content
[0003] The present invention relates to an optical path mechanism for a laser head and a laser processing device. The optical path mechanism of the laser head can change the direction of the light outlet while ensuring the accuracy of the light emitted from the light outlet.
[0004] The technical solution adopted in this utility model is an optical path mechanism for a laser head, comprising:
[0005] A first base body, wherein a first light-transmitting hole is provided in the first base body, and the first light-transmitting hole has a first light-in port and a first light-out port;
[0006] A first reflector and a second reflector are respectively disposed in the first light-transmitting hole, with the first reflector being close to the first light-in port and the second reflector being close to the first light-out port. The first reflector reflects the light entering through the first light-in port onto the second reflector, and the second reflector reflects the light reflected by the first reflector back to the first light-out port.
[0007] The second base is disposed on one side of the first base. The second base is provided with a second light-transmitting hole. The second light-transmitting hole has a second light inlet and a second light outlet. The second light inlet is close to the first light outlet and is used to receive light emitted from the first light outlet.
[0008] A third reflecting mirror and a fourth reflecting mirror are respectively disposed within the second light-transmitting aperture, with the third reflecting mirror near the second light-inlet and the fourth reflecting mirror near the second light-outlet. The third reflecting mirror reflects the light entering through the second light-inlet onto the fourth reflecting mirror, and the fourth reflecting mirror reflects the light reflected by the third reflecting mirror back to the second light-outlet.
[0009] A first driving structure is disposed on the first seat and is drivingly connected to the second seat to drive the second seat to rotate.
[0010] This application includes a first base and a second main body. The first base has a first light-transmitting hole with a first light inlet and a first light outlet.

A first reflector and a second reflector are respectively disposed in the first light-transmitting hole, and a third reflector and a fourth reflector are respectively disposed in the second light-transmitting hole. The first base is provided with a first driving structure that can drive the second base to rotate. Light entering from the first light inlet can be emitted from the second light outlet in sequence under the action of the first reflector, the second reflector, the third reflector and the fourth reflector. Therefore, when the first driving structure drives the second base to rotate, the second light outlet on the second base can rotate synchronously, thereby changing the direction of the light emitted from the second light outlet, and thus enabling processing of different positions of the workpiece.
[0011] Meanwhile, since the first body is equipped with a first reflector and a second reflector, the light entering from the first light inlet can be adjusted in four dimensions under the action of the first and second reflectors. This ensures that the light can be accurately emitted from the first light outlet and enter the second light passage of the second body through the second light inlet. Furthermore, since the second body is equipped with a third and a fourth reflector, after the light enters the second light passage through the second light inlet, the light can be adjusted in four dimensions under the action of the third and fourth reflectors to ensure that the light can be accurately emitted from the second light outlet. This ensures the accuracy of the light emitted from the second light outlet, which in turn ensures the accuracy of the light emitted by the optical path mechanism of the laser head.

The third mounting base is detachably mounted on the second base so that the third reflector is located in the second light-transmitting hole via the third mounting hole. The fourth mounting base is detachably mounted on the second base so that the fourth reflector is located in the second light-transmitting hole via the fourth mounting hole.
[0018] Optionally, the first mounting base includes a first mounting member, a second mounting member, and an adjusting member.

The adjusting member is adjustablely disposed on the second mounting member, and the end of the adjusting member is connected to the first mounting member. The adjusting member can drive the first mounting member to move. The second mounting member is detachably disposed on the first base body.
[0019] The second, third, and fourth mounting bases have the same structure as the first mounting base.
[0020] Optionally, multiple adjustment members are provided, and the multiple adjustment members are respectively connected to different positions on the first mounting member.
[0021] Optionally, it also includes a light-emitting structure having a third light-passing hole, the third light-passing hole having a third light-in port and a third light-out port, the light-emitting structure being detachably connected to the second base body, and the third light-in port being close to the second light-out port, light rays emitted through the second light-out port entering the third light-passing hole from the third light-in port and exiting from the third light-out port.

Therefore, they should not be construed as limitations on this utility model.
[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] Combination Figures 1 to 3 An optical path mechanism 100 for a laser head includes a first base 110, a second base 120, a first reflector 130a, a second reflector 130b, a third reflector 130c, a fourth reflector 130d, and a first driving structure 150.
[0038] The first housing 110 has a first light-transmitting hole, which has a first light inlet 111 and a first light outlet. Specifically, light can enter the first light-transmitting hole through the first light inlet 111 and then exit through the first light outlet. For example, laser light emitted by the laser 400 can enter the first light-transmitting hole through the first light inlet 111 and then exit through the first light outlet.
[0039] The first reflector 130a and the second reflector 130b are respectively disposed in the first light-transmitting hole, with the first reflector 130a close to the first light-in port 111 and the second reflector 130b close to the first light-out port. The first reflector 130a reflects the light entering through the first light-in port 111 onto the second reflector 130b, and the second reflector 130b reflects the light reflected by the first reflector 130a onto the first light-out port.
[0040] It is understandable that a single reflector can only adjust light in two dimensions, but it cannot center the light. However, the first housing 110 of this application is equipped with a first reflector 130a and a second reflector 130b. Therefore, light entering from the first light inlet 111 can be adjusted in four dimensions under the action of the first reflector 130a and the second reflector 130b. This ensures that the light can be accurately emitted from the first light outlet, for example, allowing the light to exit completely from the first light outlet without light loss, thus ensuring the accuracy of the light emitted from the first light outlet.
[0041] The second base 120 is disposed on one side of the first base 110. A second light-transmitting hole is provided inside the second base 120. The second light-transmitting hole has a second light inlet and a second light outlet. The second light inlet is close to the first light outlet and is used to receive light emitted from the first light outlet. Specifically, light emitted from the first light outlet enters the second light-transmitting hole through the second light inlet and then exits through the second light outlet.
[0042] The third reflector 130c and the fourth reflector 130d are respectively disposed in the second light-passing hole, with the third reflector 130c close to the second light-inlet and the fourth reflector 130d close to the second light-outlet. The third reflector 130c reflects the light entering through the second light-inlet onto the fourth reflector 130d, and the fourth reflector 130d reflects the light reflected by the third reflector 130c onto the second light-outlet.
[0043] It is understood that the second housing 120 of this application is provided with a third reflector 130c and a fourth reflector 130d respectively. Therefore, after the light emitted from the first light outlet enters the second light inlet through the second light outlet, the light can be adjusted in four dimensions under the action of the third reflector 130c and the fourth reflector 130d to ensure that the light can be accurately emitted from the second light outlet, and to ensure the accuracy of the light emitted from the second light outlet, that is, to ensure the accuracy of the light emitted by the optical path mechanism 100 of the laser head.
[0044] The first driving structure 150 is disposed on the first base 110 and is drivingly connected to the second base 120 to drive the second base 120 to rotate. It can be understood that when the first driving structure 150 drives the second base 120 to rotate, the direction of the second light-emitting port of the second base 120 can change, thus changing the direction of light rays emitted from the second light-emitting port, thereby enabling processing of different positions of the workpiece.
[0045] This application includes a first base 110 and a second main body. The first base 110 has a first light-transmitting hole with a first light inlet 111 and a first light outlet. The second base 120 has a second light-transmitting hole with a second light inlet and a second light outlet. A first reflector 130a and a second reflector 130b are respectively disposed in the first light-transmitting hole, and a third reflector 130c and a fourth reflector 130d are respectively disposed in the second light-transmitting hole. A first driving structure 150 is disposed on the first base 110. The moving structure 150 can drive the second base 120 to rotate. The light entering from the first light inlet 111 can be emitted from the second light outlet in sequence under the action of the first reflector 130a, the second reflector 130b, the third reflector 130c and the fourth reflector 130d. Therefore, when the first driving structure 150 drives the second base 120 to rotate, the second light outlet on the second base 120 can rotate synchronously, thereby changing the direction of the light emitted from the second light outlet, so that the optical path mechanism 100 of the laser head can process different positions of the workpiece.
[0046] Meanwhile, since the first reflector 130a and the second reflector 130b are respectively provided in the first base 110, the light entering from the first light inlet 111 can be adjusted in four dimensions under the action of the first reflector 130a and the second reflector 130b. This ensures that the light can be accurately emitted from the first light outlet and enter the second light passage of the second base 120 through the second light inlet. Since the second base 120 is respectively provided with the third reflector 130c and the fourth reflector 130d, after the light enters the second light passage through the second light inlet, the light can be adjusted in four dimensions under the action of the third reflector 130c and the fourth reflector 130d to ensure that the light can be accurately emitted from the second light outlet. This ensures the accuracy of the light emitted from the second light outlet, that is, the accuracy of the light emitted by the optical path mechanism 100 of the laser head.
[0047] For example, in one embodiment, the laser emitted by the laser 400 can enter the first light-transmitting hole from the first light-in port 111 along a first direction. Then, under the action of the first reflecting mirror 130a, the laser is reflected along a second direction and reflected to the second reflecting mirror 130b. The second reflecting mirror 130b reflects the laser along a third direction so that it exits from the first light-out port and enters the second light-transmitting hole from the second light-in port. The laser entering the second light-transmitting hole is emitted along the second direction by the third reflecting mirror 130c to the fourth reflecting mirror 130d. The fourth reflecting mirror 130d reflects the laser... Light is emitted from the second light-emitting port along the first direction. During this process, the first driving structure 150 can drive the second base 120 to rotate. While the second base 120 is rotating, the transmission direction of the laser emitted from the first light-emitting port and entering through the second inlet remains unchanged, allowing the laser to still enter the second light-transmitting hole along the third direction and irradiate the third reflector 130c. Although the second base 120 rotates, the laser entering the second light-transmitting hole can still accurately exit from the second light-emitting port under the action of the third reflector 130c and the fourth reflector 130d. The first direction, the second direction, and the third direction are perpendicular to each other.
[0048] Specifically, in one embodiment, in order to ensure that when the second base 120 rotates, the light emitted from the first light outlet can accurately enter the second light hole through the second inlet, the second light inlet is coaxial with the first light outlet, and the first drive structure 150 drives the second base 120 to rotate about the axis of the second light inlet.
[0049] It is understandable that, since the second light inlet and the first light outlet are coaxial, and the second base 120 rotates about the axis of the second light inlet, the second light inlet and the first light outlet can always remain coaxial when the second base 120 rotates relative to the first base 110.
[0050] In one embodiment, in order to facilitate the first driving structure 150 to drive the second seat 120 to rotate and to avoid the first rotating driving structure from blocking the light, the first driving structure 150 can be a hollow rotating platform. The hollow rotating platform is disposed between the first seat 110 and the second seat 120 and is connected to the first seat 110 and the second seat 120 respectively. The light emitted from the first light outlet can enter the second light inlet through the hollow structure of the hollow rotating platform.
[0051] Combination Figures 1 to 3The optical path mechanism 100 of the laser head may further include a first mounting base 140a and a second mounting base 140b. The first mounting base 140a mounts the first reflector 130a, and the second mounting base 140b mounts the second reflector 130b. The first base body 110 is provided with a first mounting hole and a second mounting hole communicating with the first light-transmitting hole. The first mounting base 140a is detachably mounted on the first mounting base 140a so that the first reflector 130a is located within the first light-transmitting hole via the first mounting hole. The second mounting base 140b is detachably mounted on the first mounting base 140a so that the second reflector 130b is located within the first light-transmitting hole via the second mounting hole. This structure facilitates the mounting of the first reflector 130a and the second reflector 130b within the first light-transmitting hole.
[0052] The optical path mechanism 100 of the laser head may further include a third mounting base 140c and a fourth mounting base 140d. The third mounting base 140c mounts the third reflector 130c, and the fourth mounting base 140d mounts the fourth reflector 130d. The second base 120 is provided with a third mounting hole and a fourth mounting hole communicating with the second light-transmitting hole. The third mounting base 140c is detachably mounted on the second base 120 so that the third reflector 130c is located within the second light-transmitting hole via the third mounting hole. The fourth mounting base 140d is detachably mounted on the second base 120 so that the fourth reflector 130d is located within the second light-transmitting hole via the fourth mounting hole. This structure facilitates the installation of the third reflector 130c and the fourth reflector 130d within the first light-transmitting hole.
[0053] See Figure 2 In one embodiment, to facilitate adjustment of the angle of the first reflector 130a within the first light-transmitting hole, the first mounting base 140a may include a first mounting member 141, a second mounting member 142, and an adjusting member 143. The first mounting member 141 is provided with a mounting hole (not shown in the figure), and the first reflector 130a is disposed within the mounting hole. The adjusting member 143 is adjustablely disposed on the second mounting member 142, and its end is connected to the first mounting member 141, allowing the adjusting member 143 to move the first mounting member 141. The second mounting member 142 is detachably disposed on the first base 110. The adjusting member 143 may be an adjusting bolt. One end of the adjusting bolt may be fixedly connected to or abut against the first mounting member 141.
[0054] It is understood that by adjusting the adjusting member 143, the adjusting member 143 drives the first mounting member 141, which in turn drives the first reflector 130a to move, thereby adjusting the mounting angle of the first reflector 130a.
[0055] Furthermore, to facilitate multi-angle adjustment of the first reflector 130a, multiple adjustment members 143 can be provided, and each adjustment member 143 can be connected to a different position on the first mounting member 141. For example, the multiple adjustment members 143 can be connected to the portion of the first mounting member 141 near the edge and the portion near the point where the angle is easily formed.
[0056] Furthermore, the structures of the second mounting base 140b, the third mounting base 140c, and the fourth mounting base 140d can be the same as those of the first mounting base 140a, so as to facilitate the angle adjustment of the second reflector 130b on the second mounting base 140b, the adjustment of the third reflector 130c on the third mounting base 140c, and the adjustment of the fourth reflector 130d on the fourth mounting base 140d.
[0057] See Figures 1 to 3 The optical path mechanism 100 of the laser head may also include a light-emitting structure 160. The light-emitting structure 160 has a third light-passing hole, which has a third light-in port and a third light-out port. The light-emitting structure 160 is detachably connected to the second base 120, and the third light-in port is close to the second light-out port. Light rays emitted through the second light-out port enter the third light-passing hole from the third light-in port and are emitted from the third light-out port.
[0058] It is understandable that the optical path mechanism 100 of the laser head can be adapted to different processing environments by changing different light-emitting structures 160.
[0059] See Figure 4 This application also provides a laser processing device, including a frame 200, a worktable 300, a laser 400, and an optical path mechanism 100 for the laser head in the embodiments of this application. The first base 110 of the laser 400 and the optical path mechanism 100 of the laser head is disposed on the frame 200, and the first light inlet 111 is disposed close to the laser 400. The first light inlet 111 receives the light emitted by the laser 400. The worktable 300 is disposed below the second light outlet and is used to support the workpiece.
[0060] Understandably, the laser beam emitted from the second exit port can process the workpiece on the worktable 300. Because the laser processing equipment utilizes the optical path mechanism 100 of the laser head described in this application, the processing accuracy of the laser processing equipment is high.
[0061] In another embodiment, when the optical path mechanism 100 of the laser head further includes a light-emitting structure 160, the laser emitted from the second light-emitting port is emitted to the workpiece on the worktable 300 via the third light-emitting port of the light-emitting structure 160.
[0062] Furthermore, in one embodiment, the laser processing equipment may also include a second drive structure 500 and a third drive structure 600. The second drive structure 500 is disposed on the frame 200 and is drivenly connected to the first base 110 so that the first base 110 moves along a first direction. The third drive structure 600 is drivenly connected to the worktable 300 so that the workpiece table can move along a second direction and a third direction.
[0063] Furthermore, in one embodiment, the laser processing equipment may further include a fourth drive structure 700, with the third drive structure 600 and the fourth drive structure 700 drivenly connected. The fourth drive structure 700 is drivenly connected to the worktable 300, and the fourth drive structure 700 drives the worktable 300 to rotate around its axis as a rotation axis. The axis of the worktable 300 is in a first direction. The first drive structure 150 drives the second base 120 to rotate around the axis of the second light inlet as a rotation axis. The axis of the second light inlet is in a second direction.
[0064] It is understandable that the above-mentioned laser processing equipment can realize three-dimensional five-axis laser processing, and only one drive structure is set in the optical path mechanism 100 of the laser head, which makes the size of the optical path mechanism 100 of the laser head smaller. This allows the laser head to improve the accuracy of the laser emitted by the optical path mechanism 100 by setting multiple reflectors, so as to ensure high-precision processing of the workpiece, while also avoiding the laser head's optical path mechanism 100 occupying too much space in the laser processing equipment.
[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of some utility models should be included within the protection scope of some utility models.
