Description

Technical Field

[0001] This application belongs to the field of laser processing technology, and more specifically, relates to a lens adjustment mechanism, an optical module, and a laser processing equipment. Background Technology

[0002] In laser processing equipment, the laser beam, after being output from the generator, undergoes three key optical processing stages: First, the laser beam is shaped by a beam expander and collimator to form a parallel beam with uniform energy distribution. Then, a reflector is used to change the transmission direction of the parallel beam. Finally, a focusing assembly precisely converges the direction-changed parallel beam onto the surface of the workpiece. During these three optical processing stages, machining errors and installation errors can easily cause the laser beam to deviate from the preset optical path axis. Therefore, during optical path debugging and operation, the angle of the reflector must be adjusted to correct the beam transmission direction and compensate for optical path deviations caused by machining and installation errors.

[0003] Existing mirror adjustment mechanisms mainly involve placing a ball bearing in the center of the mirror, and adjusting the mirror angle through the interaction of the ball bearing with other adjustment components. However, the contact between the ball bearing and the surrounding components is point contact, which can cause wobbling due to uneven force distribution, resulting in poor structural stability. This leads to slight misalignment of the mirror after adjustment, making it difficult to meet the long-term optical path stability requirements of high-precision laser processing equipment.

[0038] Please refer to the following: Figures 1 to 5The lens adjustment mechanism provided in the embodiments of this application will now be described.

[0039] Please see Figure 1 and Figure 2 The lens adjustment mechanism includes a mounting base 10, a frame 20, an adjusting member 30, an elastic member 40, and a fastener 50. The frame 20 is mounted on the mounting base 10 and is used to mount the lens 100. The adjusting member 30 is movably inserted through the frame 20 and connected to the mounting base 10. The adjusting member 30 is used to drive the frame 20 to move relative to the mounting base 10 to adjust the angle between the frame 20 and the mounting base 10. The elastic member 40 is movably sleeved on the adjusting member 30 and abuts against the mounting base 10 and the frame 20. The fastener 50 is movably connected to the frame 20 and the mounting base 10 and is used to lock the frame 20 onto the mounting base 10 after the angle between the frame 20 and the mounting base 10 is adjusted.

[0040] Optionally, the lens 100 can be, but is not limited to, a reflector or a beam expander. For example, if the lens 100 is a reflector, and the angle of the reflector mounted on the frame 20 needs to be fine-tuned, the fastener 50 is switched from the locked state to the unlocked state, allowing the frame 20 to move relative to the mounting base 10. The adjusting member 30 is operated, causing the frame 20 to move relative to the mounting base 10, thereby changing the angle between the frame 20 and the mounting base 10. Simultaneously, the elastic member 40 deforms accordingly due to the movement of the frame 20, such as by compression or stretching, and continuously applies an elastic force to the frame 20, helping to maintain the stability of the frame 20 during adjustment. When the angle between the frame 20 and the mounting base 10 reaches the desired value, the operation of the adjusting member 30 is stopped. Then, the fastener 50 is switched from the unlocked state to the locked state to lock the frame 20 onto the mounting base 10, thus firmly locking the frame 20 at the current angle position, thereby completing the operation of fine-tuning the angle of the reflector mounted on the frame 20.

[0041] Compared with the prior art, the lens adjustment mechanism provided in this application uses an adjusting member 30 that passes through the frame 20 and is movably connected to the mounting base 10. This allows the adjusting member 30 to move the frame 20 relative to the mounting base 10, thereby adjusting the angle between the frame 20 and the mounting base 10, and thus achieving fine-tuning of the angle of the lens 100 mounted on the frame 20. The operation is simple. By abutting the elastic member 40 between the mounting base 10 and the frame 20, it plays a good role in buffering and supporting during the adjustment process, preventing the frame 20 from shaking and making the angle adjustment more precise. Specifically, when the adjusting member 30 moves the frame 20, the elastic member 40 can absorb some of the vibration and impact generated during the adjustment process, making the movement of the frame 20 more stable and preventing damage to the frame 20 or inaccurate angle adjustment due to excessive or rapid adjustment. At the same time, the elastic force of the elastic member 40 also helps to maintain the stability of the relative position between the frame 20 and the mounting base 10, preventing the frame 20 from shaking or shifting during the adjustment process. By movably fitting the elastic element 40 onto the adjusting element 30, the elastic element 40 is guided, preventing it from shifting. By movably connecting the lens frame 20 and the mounting base 10 with the fastener 50, after the angle between the lens frame 20 and the mounting base 10 is adjusted, the fastener 50 securely locks the lens frame 20 onto the mounting base 10, preventing changes in the angle of the lens frame 20 due to external forces during use, effectively ensuring the stability of the lens 100 position. Understandably, the cooperation of the adjusting element 30, the elastic element 40, and the fastener 50 helps improve the stability of the lens adjustment mechanism during and after the lens 100 angle adjustment, thereby effectively ensuring the accuracy and stability of the lens 100 position, enabling the laser beam to transmit stably along the preset optical path axis for a long period.

[0042] Please see Figure 3 Optionally, the mounting base 10 is provided with a mounting surface 11. When the mounting base 10 is placed horizontally, the mounting surface 11 is inclined relative to the horizontal plane, the frame 20 is disposed on the mounting surface 11, and the lens 100 is parallel to the mounting surface 11.

[0043] Optionally, the mounting base 10 is provided with a mounting groove 111, which extends through the mounting surface 11, and a portion of the frame 20 is accommodated within the mounting groove 111.

[0044] Combined with appendix Figures 1 to 3It is understood that the frame 20 has a first threaded hole, and the mounting base 10 has a second threaded hole 12. The second threaded hole 12 passes through the mounting surface 11 and corresponds to the first threaded hole on the frame 20. The adjusting member 30 is a stud, which passes through the first threaded hole and has one end inserted into the second threaded hole 12. The adjusting member 30 is threadedly engaged with both the first threaded hole and the second threaded hole 12. By rotating the adjusting member 30 relative to the frame 20, the frame 20 rotates relative to the mounting base 10, causing a portion of the frame 20 to move away from or closer to the mounting base 10, thereby adjusting the angle between the frame 20 and the mounting base 10.

[0045] The above technical solution, by threading the adjusting member 30 into the first threaded hole on the lens frame 20, utilizes the characteristics of threaded transmission to achieve a minute displacement of the lens frame 20 relative to the mounting base 10. Specifically, the threaded transmission has a precise transmission ratio; for every certain angle rotation of the adjusting member 30, the lens frame 20 can produce a predictable minute angle change, thereby achieving high-precision fine-tuning of the lens angle 100°, meeting the stringent precision requirements for the lens angle 100° in the laser optical path. Furthermore, during adjustment, the threaded engagement of the adjusting member 30 with the first threaded hole on the lens frame 20 provides continuous support for the lens frame 20. Simultaneously, the buffering effect of the elastic member 40 effectively reduces the shaking of the lens frame 20 during adjustment, ensuring the stability of the relative position of the lens frame 20 and the mounting base 10 during the adjustment process. By threading one end of the adjusting member 30 into the second threaded hole 12 on the mounting base 10, a more stable connection is formed between the adjusting member 30 and the mounting base 10. This effectively prevents the adjusting member 30 from loosening or shifting during adjustment, providing a stable support base for the angle adjustment of the frame 20. Of course, one end of the adjusting member 30 can also directly abut against the mounting surface 11 of the mounting base 10.

[0046] Optionally, the adjusting element 30 may be, but is not limited to, screws or bolts.

[0047] Alternatively, the frame 20 may have a movable hole and a rotatable pinion. The adjusting member 30 is a toothed rack that movably passes through the movable hole and meshes with the pinion. One end of the adjusting rod is connected to the mounting base 10. By rotating the pinion, a portion of the frame 20 is indirectly moved away from or closer to the mounting base 10 to adjust the angle between the frame 20 and the mounting base 10.

[0048] Combined with appendix Figure 1 and Figure 2 It is understandable that there are multiple adjustment components 30, which are distributed at intervals along the circumference of the frame 20, and each adjustment component 30 is movably fitted with an elastic component 40.

[0049] By distributing multiple adjustment components 30 circumferentially along the frame 20, different adjustment components 30 can be operated to apply forces to the frame 20 from multiple directions, thereby achieving fine-tuning of the lens angle by more than 100 degrees, making the lens angle more precise. Each adjustment component 30 is fitted with an elastic element 40. During adjustment, when the adjustment component 30 moves the frame 20, each elastic element 40 will simultaneously undergo corresponding deformation, such as compression or stretching, applying elastic forces to multiple parts of the frame 20, forming a more stable support and buffer structure, which helps to improve the stability of the adjustment process.

[0050] Combined with appendix Figure 2 and Figure 4 It is understood that there are four adjusting members 30, which are arranged in a rectangular pattern along the circumference of the frame 20. By arranging the four adjusting members 30 in a rectangular pattern along the circumference of the frame 20, the four adjusting members 30 adjust the frame 20 from four different angles, achieving more precise angle adjustment. Furthermore, the four adjusting members 30 apply force to four different positions of the frame 20, which helps to improve the stability of the lens adjustment mechanism.

[0051] Optionally, the frame 20 has a rectangular structure, and four adjustment pieces 30 are respectively located at the four corners of the frame 20.

[0052] Alternatively, the number of adjustment components 30 can be two, three, five, or more, depending on the size of the frame 20 and the required adjustment precision. Of course, the number of adjustment components 30 can also be one.

[0053] Combined with appendix Figure 3 and Figure 4 It is understood that the mounting base 10 has a first limiting groove 13 on the side facing the frame 20, and the frame 20 has a second limiting groove on the side facing the mounting base 10. The second limiting groove on the frame 20 is coaxially opposite to the first limiting groove 13, and both ends of the elastic member 40 are respectively limited within the first limiting groove 13 on the mounting base 10 and the second limiting groove on the frame 20. Specifically, the first limiting groove 13 extends through the mounting surface 11. The first limiting groove 13 and the second limiting groove on the frame 20 provide good fixation and guidance for the elastic member 40, effectively preventing the frame 20 from tilting due to the bias of the elastic force.

[0054] Optionally, the elastic element 40 may be, but is not limited to, a coil spring or an elastic rubber sleeve.

[0055] Alternatively, the two ends of the elastic element 40 can be connected to the mounting base 10 and the frame 20, respectively. Or, one end of the elastic element 40 can abut against the mounting surface 11, and the other end of the elastic element 40 can abut against the side of the frame 20 facing the mounting surface 11.

[0056] Combined with appendix Figure 2 and Figure 3 It is understood that the mounting base 10 has a fixing hole 14, and the frame 20 has a third threaded hole. The fastener 50 passes through the third threaded hole on the frame 20 and is threadedly engaged with the third threaded hole on the frame 20, with one end of the fastener 50 inserted into the fixing hole 14. The threaded engagement between the fastener 50 and the third threaded hole on the frame 20, with one end of the fastener 50 inserted into the fixing hole 14 of the mounting base 10, effectively ensures the stability of the connection between the frame 20 and the mounting base 10. Furthermore, because the fastener 50 and the third threaded hole on the frame 20 are threadedly engaged, the operator can precisely control the tightness of the fastener 50 by tightening it, facilitating quick switching between the locked and unlocked states of the fastener 50.

[0057] Optionally, fastener 50 may be, but is not limited to, screws or bolts.

[0058] Alternatively, the fastener 50 can be a snap-fit ​​or a spring clip, etc. For example, the fastener 50 is a spring clip that is rotatably connected to the mounting base 10. After the angle between the frame 20 and the mounting base 10 is adjusted, the spring clip elastically holds the frame 20 on the mounting base 10, thereby locking the frame 20 on the mounting base 10.

[0059] Combined with appendix Figure 1 and Figure 2 It is understood that there are multiple fasteners 50, which are distributed circumferentially along the frame 20. By distributing multiple fasteners 50 circumferentially along the frame 20, after the frame 20 angle is adjusted, the multiple fasteners 50 apply locking force to the frame 20 from multiple different positions, making the force on the frame 20 more uniform. This avoids localized force concentration on the frame 20, which could lead to damage or misalignment. At the same time, it makes the connection between the frame 20 and the mounting base 10 tighter and more stable, which helps to improve the overall stability of the lens adjustment mechanism.

[0060] Combined with appendix Figure 2 and Figure 4 It is understood that there are three fasteners 50, which are arranged in a triangle along the circumference of the frame 20. By arranging the three fasteners 50 in a triangle along the circumference of the frame 20, the triangle has stable geometric properties. After the angle between the frame 20 and the mounting base 10 is adjusted, the three fasteners 50 form a stable locking constraint on the frame 20 from three different directions, so as to securely lock the frame 20 onto the mounting base 10.

[0061] Alternatively, the number of fasteners 50 can be two, four, or more, depending on the requirements. Of course, the number of fasteners 50 can also be one.

[0062] Combined with appendix Figure 2 and Figure 4 It is understood that the frame 20 is provided with a receiving cavity 21 for accommodating the lens 100. By accommodating the lens 100 in the receiving cavity 21, the lens 100 is positioned to limit its movement, allowing it to quickly fall into the preset position during installation and reducing positional deviations during manual placement.

[0063] Combined with appendix Figure 2 and Figure 3 It is understandable that the mounting base 10 is provided with two light guide channels 15, both of which are connected to the receiving cavity 21.

[0064] Specifically, the receiving cavity 21 extends through the side of the frame 20 facing the mounting base 10 and the side of the frame 20 away from the mounting base 10.

[0065] For example, when the lens 100 is a reflector and is installed in the receiving cavity 21, the external laser beam is incident on the surface of the reflector in the receiving cavity 21 through one of the light guide channels 15. After being reflected by the reflector and changing its propagation direction, it is emitted through another light guide channel 15, thus completing the reflection-guided transmission of the laser beam.

[0066] The above technical solution provides a clear and closed transmission channel for light by directly connecting the two light guide channels 15 on the mounting base 10 with the receiving cavity 21 on the lens frame 20. This design avoids energy loss caused by scattering, diffuse reflection and other reasons during light transmission, and improves the transmission efficiency of light.

[0067] Combined with appendix Figure 1 and Figure 2 It is understood that the lens adjustment mechanism also includes a fixing member 60, which is movably connected to the frame 20. The fixing member 60 is used to detachably fix the lens 100 to the frame 20. The fixing member 60 stably fixes the lens 100 to the frame 20, preventing the lens 100 from becoming loose, shifting, or wobbling on the frame 20. At the same time, since the fixing member 60 is movably connected to the frame 20, when the lens 100 is damaged, needs to be upgraded, or requires regular maintenance, the lens 100 can be removed from the frame 20, a new lens 100 can be installed, and the fixing member 60 can be readjusted for positioning and fixation.

[0068] Combined with appendix Figure 2 and Figure 4It is understood that the frame 20 has a mounting area and a fourth threaded hole. The mounting area is used to place the lens 100. The fourth threaded hole on the frame 20 is located on the outer edge of the mounting area. The fastener 60 includes a screw 61 and a pressure block 62. The screw 61 is inserted into the fourth threaded hole on the frame 20 and is threadedly engaged with the fourth threaded hole. The pressure block 62 is located on the side of the frame 20 away from the mounting base 10 and is connected to the screw 61. The pressure block 62 is used to press the lens 100 into the mounting area.

[0069] Specifically, the receiving cavity 21 is located in the installation area.

[0070] When installing lens 100, first place lens 100 in the installation area, that is, place lens 100 in the receiving cavity 21, and then rotate screw 61 to gradually bring pressure block 62 closer to and press lens 100, thus completing the installation. The operation is simple and convenient. Similarly, when removing lens 100, simply rotate screw 61 in the opposite direction to loosen pressure block 62, and lens 100 can be easily removed. This design greatly shortens the installation and removal time of lens 100 and improves the maintenance efficiency of the equipment. In addition, by adopting the threaded engagement structure of screw 61 and fourth threaded hole, the clamping force can be flexibly adjusted according to the thickness or material of lens 100, preventing excessive pressure from damaging lens 100 or insufficient pressure from causing lens 100 to shift. Moreover, the threaded engagement has self-locking properties, which can maintain a stable clamping state after adjustment, preventing lens 100 from loosening during use or adjustment of the frame angle 20.

[0071] Optionally, fastener 50 may be, but is not limited to, screws or bolts.

[0072] Alternatively, the fixing element 60 includes a rotating block and a torsion spring. The rotating block is rotatably connected to the frame 20, and the torsion spring abuts against the rotating block and the frame 20. Under the action of the torsion spring, the rotating block can press the lens 100 onto the frame 20. Alternatively, the frame 20 can be made of a metal material that can attract magnets, such as iron, nickel, or cobalt. The fixing element 60 is a magnetic block, with part of the magnetic block magnetically attracting the frame 20 and the other part pressing against the lens 100, thereby locking the magnetic block onto the frame 20.

[0073] Combined with appendix Figure 1 and Figure 2 It is understood that there are multiple fasteners 60, which are distributed at intervals along the circumferential edge of the mounting area. Specifically, when the lens 100 is placed on the mounting area, the multiple fasteners 60 press against different positions on the circumferential edge of the lens 100.

[0074] The above technical solution, by distributing multiple fasteners 60 at intervals along the circumferential edge of the installation area and pressing the multiple fasteners 60 against different positions of the circumferential edge of the lens 100, helps to improve the stability of the lens 100 fixed on the frame 20. At the same time, the multiple fasteners 60 apply pressure simultaneously from different positions of the circumferential edge of the lens 100, avoiding localized force concentration on the lens 100, which could cause the lens 100 to warp or shift.

[0075] It should be noted that the position and number of the fasteners 60 can be flexibly adjusted according to the actual shape and size of the lens 100 to ensure effective fixation of lenses 100 of various shapes and sizes. Understandably, the number of fasteners 60 can also be one.

[0076] Combined with appendix Figure 2 and Figure 4 It is understood that there are two fasteners 60, symmetrically arranged about the central axis of the installation area. By using two fasteners 60 and symmetrically arranging them about the central axis of the installation area, a balanced clamping force is applied from both sides of the lens 100, preventing warping, displacement, or stress deformation of the lens 100 due to single-point or asymmetrical force. Furthermore, the symmetrical design of the two fasteners 60 allows operators to quickly grasp the installation rhythm; by symmetrically operating the fasteners 60, the lens 100 can be quickly fixed or removed.

[0077] Alternatively, the number of fasteners 60 can be three or more.
