Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to a beam adjustment device and laser equipment. Background Technology

[0002] Lasers are one of the core components of laser processing systems. Laser processing is a technology that utilizes the energy of light, which is focused by a lens to achieve a very high energy density at the focal point, and then processes the light through a photothermal effect.

[0003] In related technologies, during the production process of laser processing, a visible indicator light is used to indicate the position of the laser. However, in related technologies, the relative positions of the indicator light generator and the laser generator are usually adjusted and fixed before leaving the factory. This method may cause the indicator light and the laser to shift during transportation, resulting in the indicator light failing to indicate the laser during use. Utility Model Content

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0060] This utility model proposes a beam adjustment device.

[0061] In the embodiments of this utility model, such as Figures 1 to 3 As shown, the beam adjustment device includes a base 1, an indicator light generator 2, a beam combiner 3, a first adjustment mechanism 4, and a second adjustment mechanism 5. One side of the beam combiner 3 is positioned opposite the laser generator, and the other side is positioned opposite the indicator light generator 2. It transmits the laser beam emitted by the laser generator and reflects the indicator beam emitted by the indicator light generator 2, or reflects the laser beam emitted by the laser generator and transmits the indicator beam emitted by the indicator light generator 2, so that the laser beam and the indicator beam are emitted from the same side of the beam combiner 3. The first adjustment mechanism 4 is movably mounted on the base 1. The second adjustment mechanism 5 is rotatably mounted on the base 1. The indicator light generator 2 is mounted on one of the first adjustment mechanism 4 and the second adjustment mechanism 5, and the beam combiner 3 is mounted on the other of the first adjustment mechanism 4 and the second adjustment mechanism 5.

[0062] In this embodiment, the base 1 serves to support and mount the various components of the beam adjustment device (indicator light generator 2, beam combiner 3, first adjustment mechanism 4, and second adjustment mechanism 5, etc.). The specific structure of the base 1 is not limited here; for example, it can be a frame structure, a plate structure, a cylindrical structure, or other structures. The indicator light generator 2 emits an indicator beam. In practical applications, the indicator beam can be selected as visible red light for easy observation by personnel. The beam combiner 3 can transmit the laser beam and reflect the indicator beam, or reflect the laser beam and transmit the indicator beam, so that the laser beam and the indicator beam can be emitted from the same surface of the beam combiner 3. Optionally, the base 1 includes a first sidewall 11 and a second sidewall 12 disposed opposite to each other, and a third sidewall 13 connecting the first sidewall 11 and the second sidewall 12. The first sidewall 11 is provided with a laser beam inlet 101, the second sidewall 12 is provided with a light outlet 102, and the third sidewall 13 is provided with an indicator light inlet 103. The indicator light generator 2 is disposed at the third sidewall 13, and the beam combiner 3 is obliquely disposed between the first sidewall 11 and the second sidewall 12. One side of the beam combiner 3 faces the laser beam inlet 101, and the other side faces the indicator light inlet 103 and the light outlet 102. The laser beam emitted by the laser generator enters through the laser beam inlet 101 and irradiates the first side of the beam combiner 3. The indicator light emitted by the indicator light generator 2 irradiates the second side of the beam combiner 3 through the indicator light inlet 103. After the laser beam is transmitted and the indicator light is reflected by the beam combiner 3, both the laser beam and the indicator light can be emitted from the light outlet 102.

[0063] The base 1 is equipped with a movable first adjustment mechanism 4 and a rotatable second adjustment mechanism 5. The indicator light generator 2 is mounted on one of the first adjustment mechanism 4 and the second adjustment mechanism 5, and the beam combiner 3 is mounted on the other. This allows one of the indicator light generator 2 and the beam combiner 3 to move relative to the base 1, while the other can rotate relative to the base 1. By combining rotation and movement, the position and emission angle of the indicator light generator 2 and the beam combiner 3 can be adjusted, enabling the adjustment of the coaxial or parallel emission of the laser beam and the indicator beam. It should be noted that in this embodiment, the adjusted laser beam and indicator beam can be coaxially or parallelly emitted. When coaxially emitted, the laser beam and the indicator beam coincide, and the optical path of the laser beam can be directly characterized by the optical path of the indicator beam. When parallelly emitted, the distance between the optical paths of the laser beam and the indicator beam is fixed, and the optical path of the laser beam can be determined by the optical path of the indicator beam and the predetermined distance information.

[0064] As an example, please refer to Figure 4 and Figure 5 ,in Figure 4 This is a schematic diagram comparing the adjustment of the indicator light generator 2 by the first adjustment mechanism 4 before and after adjustment. Figure 5 This is a schematic diagram comparing the adjustment of the second adjustment mechanism 5 and the beam combiner 3 before and after adjustment. In actual adjustment, at least two observation points can be set on the output light path. For ease of explanation, two observation points are used as an example. The one closer to the light source is the first observation point (which can be marked with masking tape), and the one farther from the light source is the second observation point (which can also be marked with masking tape). First, control the laser beam to strike the first observation point. Adjust the corresponding first adjustment mechanism 4 to shift the indicator light generator 2 so that the indicator beam coincides with the laser point at the first observation point. Figure 4 The first adjustment mechanism 4 drives the indicator light generator 2 to move to the right (in the direction shown in the diagram); then, observing the second observation point, the corresponding second adjustment mechanism 5 is adjusted to deflect the beam combiner 3 so that the indicator beam and the laser point coincide at the second observation point, as shown. Figure 5 The second adjustment mechanism 5 drives the beam combiner 3 to deflect clockwise (as shown in the diagram). Based on the principle that two points form a line, the laser and the indicator beam can be adjusted to coincide, achieving coaxial emission. This design is simple and easy to operate. Pre-adjustment can be performed at the production end; if the laser indicator beam deviates due to transportation or replacement of the laser tube, further fine-tuning can be performed. Furthermore, because this device has an adjustment function, the processing accuracy and assembly difficulty of the entire laser equipment are greatly reduced.

[0065] Understandably, the specific structure of the first adjusting mechanism 4 can be determined according to the actual situation. For example, it can be an electrically controlled adjusting mechanism, such as an adjusting mechanism driven by a motor or cylinder, or it can be a manually controlled adjusting mechanism, such as a combination of hand-tightening screws and drive screws. Correspondingly, the specific structure of the second adjusting mechanism 5 can also be determined according to the actual situation. For example, it can be an electrically controlled adjusting mechanism, such as an adjusting mechanism driven by a motor or cylinder, or it can be a manually controlled adjusting mechanism, such as a combination of hand-tightening screws and drive screws.

[0066] In summary, the beam adjustment device of this utility model, by setting a movable first adjustment mechanism 4 and a rotatable second adjustment mechanism 5 on the base 1, with the indicator light generator 2 mounted on one of the first adjustment mechanism 4 and the second adjustment mechanism 5, and the beam combiner 3 mounted on the other, allows for position and / or angle adjustment of the indicator light generator 2 and the beam combiner 3 when the laser beam and the indicator beam are offset after transmission and reflection through the beam combiner 3. This enables the laser beam and the indicator beam to be emitted coaxially or parallel, and allows the indicator beam to characterize the optical path of the laser beam. When applied to laser processing equipment, it can improve the processing accuracy of the laser equipment.

[0067] Please see Figures 1 to 5 In one embodiment of this application, the indicator light generator 2 is installed on the first adjustment mechanism 4, which can drive the indicator light generator 2 to move along the first direction and the second direction. The first direction, the second direction and the axis of the indicator light beam intersect each other. The beam combiner 3 is installed on the second adjustment mechanism 5, which is used to drive the beam combiner 3 to deflect.

[0068] With this design, the first adjustment mechanism 4 can drive the indicator light generator 2 to move in the first and second directions, thus enabling the positional adjustment of the indicator beam. Figure 4 The second adjustment mechanism 5 can drive the beam combiner 3 to deflect relative to the base 1, thereby adjusting the incident angle of the indicator beam onto the beam combiner 3, and thus adjusting the exit angle of the indicator beam after reflection by the beam combiner 3. Figure 5 Therefore, by adjusting the position and the emission angle, the coaxial adjustment function of the indicator beam and the laser beam can be achieved.

[0069] Understandably, if the first adjustment mechanism 4 moves the indicator light generator 2 along the axis of the indicator beam, it will not change the emission position and angle of the indicator beam. In this embodiment, the first direction, the second direction, and the axis of the indicator beam intersect each other, enabling adjustment of the emission position of the indicator beam. Optionally, the first direction, the second direction, and the axis of the indicator beam are orthogonal to each other.

[0070] Optionally, the second adjustment mechanism 5 is used to drive the beam combiner 3 to deflect around the first direction and / or the second direction. This enables adjustment of the indicator beam emission angle at multiple angles.

[0071] In practical applications, the specific structure of the first adjustment mechanism 4 and the specific structure of the second adjustment mechanism 5 can be determined according to the actual situation. The first adjustment mechanism 4 and the second adjustment mechanism 5 are illustrated below by way of example.

[0072] Please see Figures 1 to 4 In one embodiment of this application, the first adjustment mechanism 4 includes a first moving component 41 and a second moving component 4242. The first moving component 41 is movably disposed on one side of the base 1 in a first direction; the second moving component 4242 is movably disposed on the first moving component 41 in a second direction, and the indicator light generator 2 is mounted on the second moving component 4242.

[0073] In this embodiment, the second moving component 4242 can drive the indicator light generator 2 to move along the second direction, and the first moving component 41 can drive the second moving component 4242 and the indicator light generator 2 to move together along the first direction. The first moving component 41 and the second moving component 4242 enable the movement adjustment function of the indicator light generator 2 in the first and second directions.

[0074] Specifically, the first moving component 41 includes a first slide block 411, a first guide member 412, and a first adjusting member 413. The first slide block 411 is provided with a first guide groove 4111 extending along a first direction. The second moving component 4242 is mounted on the first slide block 411. The first guide member 412 is slidably engaged with the first guide groove 4111 for connection and fixation with the base 1. The first adjusting member 413 connects the first slide block 411 and the base 1 to drive the first slide block 411 to move along the first direction. In this embodiment, the first guide member 412 and the first guide groove 4111 are slidably engaged to achieve the function of pre-positioning the first slide block 411 and the base 1. When adjustment is required, the first adjusting member 413 drives the first slide block 411 to move, causing the first guide groove 4111 to slide relative to the first guide member 412, thereby enabling the first slide block 411 to move along the first direction, and thus driving the second moving component 4242 and the indicator light generator 2 mounted thereon to move along the first direction.

[0075] Optionally, the base 1 is provided with a first connecting plate 14, the first connecting plate 14 being provided with a first mounting hole 141 extending along a first direction; the first slide 411 is provided with a first push plate 4112 disposed opposite to the first mounting hole 141; the first adjusting member 413 includes a first adjusting screw 4131 and a first elastic member 4132, the first adjusting screw 4131 being screwed into the first mounting hole 141, the end of the first adjusting screw 4131 abutting against the first push plate 4112; the first elastic member 4132 connecting the first push plate 4112 and the first connecting plate 14.

[0076] The first adjusting screw 4131 is screwed into the first mounting hole 141 along the first direction. When adjustment is required, the first adjusting screw 4131 is rotated, and the first adjusting screw 4131 will move relative to the first connecting plate 14 of the base 1 in the first direction. As a result, the end of the first adjusting screw 4131 will push or move away from the first push plate 4112. Since the first push plate 4112 and the first connecting plate 14 are connected by a first elastic element 4132, when the first adjusting screw 4131 moves away from the first push plate 4112, the first elastic element 4132 can drive the first push plate 4112 to move toward the first adjusting screw 4131 until it abuts against the end of the first adjusting screw 4131, thereby realizing the function of the first slide block 411 reciprocating along the first direction.

[0077] Optionally, the first adjusting screw 4131 may be a hand-tightening screw or a set screw; optionally, the first elastic element 4132 may be a spring.

[0078] Optionally, the first guide member 412 includes a first head 4121, a first sliding portion 4122, and a first threaded portion 4123 connected in sequence. The first head 4121 abuts against the first slide block 411, the first sliding portion 4122 slidably engages with the first guide groove 4111, and the first threaded portion 4123 is screwed and fixed to the base 1. With this design, after the first slide block 411 is adjusted to the correct position, it can be fixed by fastening the first threaded portion 4123 to the base 1. Optionally, the first guide member 412 is a plug screw.

[0079] Specifically, the second moving component 4242 includes a second slide 421, a second guide 422, and a second adjusting component 423. The second slide 421 has a second guide groove 4211 extending along a second direction. The indicator light generator 2 is mounted on the second slide 421 and is positioned opposite to the beam combiner 3. The second guide 422 is slidably engaged with the second guide groove 4211 for connection and fixation with the first slide 411. The second adjusting component 423 connects the first slide 411 and the second slide 421 to drive the second slide 421 to move along the second direction. In this embodiment, the second guide 422 and the second guide groove 4211 are slidably engaged to achieve the pre-positioning function of the second slide 421. When adjustment is required, the second adjusting component 423 drives the second slide 421 to move, causing the second guide groove 4211 to slide relative to the second guide 422, thereby moving the second slide 421 along the second direction and thus driving the indicator light generator 2 mounted thereon to move along the second direction. Optionally, the indicator light generator 2 is fixed to the second slide 421 by means of locking, threading, or bonding.

[0080] A second connecting plate 4113 is provided on one side of the first slide block 411, and the second connecting plate 4113 is provided with a second mounting hole 41131 that extends through in a second direction; the second slide block 421 is provided with a second push plate 4212 that is opposite to the second mounting hole 41131; the second adjusting member 423 includes a second adjusting screw 4231 and a second elastic member 4232, the second adjusting screw 4231 is screwed into the second mounting hole 41131, and the end of the second adjusting screw 4231 abuts against the second push plate 4212; the second elastic member 4232 connects the second push plate 4212 and the second connecting plate 4113.

[0081] The second adjusting screw 4231 is screwed into the second mounting hole 41131 along the second direction. When adjustment is required, the second adjusting screw 4231 is rotated, and the second adjusting screw 4231 will move relative to the second connecting plate 4113 of the first slide 411 in the second direction. As a result, the end of the second adjusting screw 4231 will push or move away from the second push plate 4212. Since the second push plate 4212 and the second connecting plate 4113 are connected by a second elastic member 4232, when the second adjusting screw 4231 moves away from the second push plate 4212, the second elastic member 4232 can drive the second push plate 4212 to move toward the second adjusting screw 4231 until it abuts against the end of the second adjusting screw 4231, thereby realizing the function of the second slide 421 reciprocating along the second direction.

[0082] Optionally, the second adjusting screw 4231 can be a hand-tightening screw or a set screw, etc.; optionally, the second elastic element 4232 can be a spring.

[0083] Optionally, the second guide member 422 includes a second head 4221, a second sliding portion 4222, and a second threaded portion 4223 connected in sequence. The second head 4221 abuts against the second slide block 421, the second sliding portion 4222 slidably engages with the second guide groove 4211, and the second threaded portion 4223 is screwed and fixed to the first slide block 411. With this design, after the second slide block 421 is adjusted to its position, it can be fixed by tightening the second threaded portion 4223 to the first slide block 411. Optionally, the second guide member 422 is a plug screw.

[0084] Please see Figures 1 to 3 as well as Figure 5 In one embodiment of this application, the second adjustment mechanism 5 includes an adjustment plate 51 and a third adjustment member 52. The adjustment plate 51 is disposed on the side of the base 1 away from the indicator light generator 2, and the beam combiner 3 is fixedly disposed on the side of the adjustment plate 51 facing the indicator light generator 2. The third adjustment member 52 connects the adjustment plate 51 and the base 1 and is used to drive the adjustment plate 51 to deflect relative to the base 1.

[0085] This embodiment illustrates the second adjustment mechanism 5. The beam combiner 3 is fixedly installed on the adjustment plate 51. The adjustment plate 51 is connected to the base 1 through the third adjustment member 52. When it is necessary to adjust the beam combiner 3, the adjustment plate 51 can be adjusted to deflect relative to the base 1 through the third adjustment member 52, so as to drive the beam combiner 3 to deflect.

[0086] Specifically, the adjusting plate 51 is provided with two third mounting holes 511 that pass through in a third direction. The two third mounting holes 511 are staggered in both the first and second directions. The third adjusting member 52 includes two third adjusting screws 521 and a third elastic member 522. The two third adjusting screws 521 are respectively screwed into the two third mounting holes 511, and the ends of the third adjusting screws 521 abut against the base 1. The third elastic member 522 connects the base 1 and the adjusting plate 51.

[0087] By providing two third mounting holes 511 along a third direction, which are offset in both the first and second directions, optionally, the third direction is orthogonal to both the first and second directions, enabling the adjustment plate 51 to rotate around the first and second directions. Two third adjusting screws 521 pass through the two third mounting holes 511 and abut against the base 1. When adjustment is needed, the two third adjusting screws 521 can be rotated individually or simultaneously, causing them to move in the third direction. This pushes the corresponding part of the adjusting plate 51 closer to or further away from the base 1. When the adjustment distances of the two third adjusting screws 521 are different, different angles of deflection of the adjusting plate 51 can be achieved.
