Description

Technical Field

[0001] This application belongs to the field of optical path coupling technology, specifically relating to an optical path coupling device. Background Technology

[0002] As a core optoelectronic device capable of outputting high-brightness, high-collimation, and high-monochromatic laser beams, lasers have been widely used in numerous fields such as industrial precision machining, laser communication, optical inspection, scientific research experiments, and medical equipment due to their excellent optical performance. With the continuous iteration and upgrading of technologies across various industries, the market's requirements for laser beam quality, output stability, and optical path transmission accuracy are constantly increasing. As the core component of a laser, the assembly accuracy and coupling effect of the optical path system directly determine the overall working performance and reliability of the laser.

[0003] In the assembly and debugging of laser optical path systems, optical coupling is a critical and core process. Its core purpose is to ensure that the laser beam transmits stably along a preset trajectory, minimizes optical path transmission loss, and guarantees that the laser output power and beam quality meet the standards. Optical path systems typically employ multiple sets of reflectors and other optical lenses. These reflectors redirect and reflect the laser beam, thereby completing the overall construction and coupling matching of the optical path. The installation status of the reflectors directly affects the coupling accuracy of the entire optical path. Traditionally, reflectors are installed manually, but manual installation has lower precision, easily leading to lower laser output power and beam quality in the laser optical path system. Summary of the Invention

The gripping mechanism includes a gripping moving component, a detection component, a gripping adjusting component, and a gripping component. The gripping moving component is connected to the detection component and the gripping adjusting component to drive the detection component and the gripping adjusting component to perform three-dimensional motion.

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0024] 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 at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] To facilitate understanding of the technical solution of this application, it should be noted that the main problem with manually installing reflectors is that the reflectors are prone to significant angular deviations, causing the optical path to fail to transmit stably along the preset trajectory, thus affecting the laser output power and beam quality. This application provides an optical path coupling device capable of installing reflectors in the laser optical path system, ensuring that the installed reflectors have no or minimal angular deviation, i.e., high installation precision, thereby guaranteeing that the laser output power and beam quality meet the standards.

[0029] like Figure 1 As shown, in one embodiment, the optical path coupling device includes a large board 10 and a gripping mechanism 100, a transmitting mechanism 200, a receiving mechanism 300, and a carrying mechanism 400 disposed on the large board 10.

[0030] The support mechanism 400 can support the optical device 20 and the optical component 30. This optical path coupling device is mainly used to install the optical component 30 into the optical device 20 and ensure high installation accuracy of the optical component 30. The optical device 20 can be a laser 212 or other equipment, and the optical component 30 can be a mirror, a PBS (Polarizing Beam Splitter), or other devices capable of changing the direction of the beam. Furthermore, in this embodiment, the optical path coupling device uses a gripping mechanism 100 to grip the optical component 30 on the support mechanism 400 and install the optical component 30 into the optical device 20.

[0031] The transmitting mechanism 200 is capable of emitting a light beam propagating in a first direction, and the receiving mechanism 300 is capable of receiving a light beam propagating in a second direction. Please also refer to... Figure 2The gripping mechanism 100 includes a gripping movement component 110, a detection component 120, a gripping adjustment component 130, and a gripping component 140. The gripping movement component 110 is connected to the detection component 120 and the gripping adjustment component 130 to drive the detection component 120 and the gripping adjustment component 130 to perform three-dimensional motion. The detection component 120 is used to detect the position of the optical device 20 and the optical device 30. The gripping adjustment component 130 is connected to the gripping component 140 to drive the gripping component 140 to rotate around the axes of the first direction, the second direction, and the third direction, respectively. The gripping component 140 is used to grip and release the optical device 30.

[0032] Among them, after the grasping component 140 grasps the optical device 30, the grasping moving component 110 can drive the optical device 30 to move onto the beam path of the transmitting mechanism 200, and the grasping adjusting component 130 can drive the optical device 30 to rotate until the optical device 30 reflects the beam to the receiving mechanism 300.

[0033] It should be noted that the supporting mechanism 400 can also position the optical device 20. In the positioned optical device 20, the optical component 30 can deflect the beam direction, and the incident beam of the optical component 30 propagates along one of the first and second directions. The installation requirement for the optical component 30 is to ensure that the reflected beam of the optical component 30 propagates along the other of the first and second directions. Figure 1 In the illustrated embodiment, the incident beam of the optical device 30 is transmitted along a first direction, and the installation requirement for the optical device 30 is to ensure that the reflected beam of the optical device 30 is transmitted along a second direction. Therefore, when determining whether the installation angle of the optical device 30 meets the standard, it is only necessary to observe whether the optical device 30 can deflect the beam transmitted in the first direction to the second direction.

[0034] Furthermore, the grasping and moving component 110 can drive the detection component 120 and the grasping and adjusting component 130 to move along the first direction, the second direction and the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0035] The operation procedure of the optical path coupling device is as follows: The detection component 120 first detects the positions of the optical device 20 and the optical component 30 on the support mechanism 400. The grasping and moving component 110 drives the grasping component 140 to approach the support mechanism 400 and grasp the optical component 30 based on the detection data. Next, the grasping and moving component 110 drives the optical component 30 to move into the path of the beam emitted by the transmitting mechanism 200, so that the optical component 30 reflects the beam. The grasping and adjusting component 130 drives the optical component 30 to rotate, thereby adjusting the angle of the optical component 30 and adjusting the direction of the beam reflected by the optical component 30 until the optical component 30 reflects the beam to the receiving mechanism 300. At this point, the optical component 30 can deflect the beam in the first direction to the second direction, and its angle meets the installation requirements. Therefore, the gripping adjustment component 130 is stationary, the gripping movement component 110 drives the optical device 30 to move toward the support mechanism 400, and drives the optical device 30 to approach the optical device 20 according to the detection data. When the optical device 30 moves to the installation position of the optical device 30 on the optical device 20, the gripping component 140 releases the optical device 30.

[0036] It should be explained that the installation position of the optical device 30 in the optical equipment 20 is already determined. The optical path coupling device is mainly used to determine the installation angle of the optical device 30 to ensure that the angle installation accuracy meets the requirements. At the same time, the detection component 120 can detect the position of the optical equipment 20 and the optical device 30, and can also detect the installation position of the optical device 30 in the optical equipment 20 to ensure the installation accuracy in position. In addition, the angle of the optical device 30 is adjusted by the gripping adjustment component 130. After the gripping adjustment component 130 is stationary, the angle of the optical device 30 will not change during the movement of the optical device 30 driven by the gripping moving component 110, thereby ensuring that the angle installation accuracy of the optical device 30 meets the requirements.

[0037] Using the aforementioned optical path coupling device, the grasping component 140 grasps the optical device 30 based on the detection result of the detection component 120, and then moves it onto the beam path of the transmitting mechanism 200. The grasping adjustment component 130 adjusts the angle of the optical device 30 until the optical device 30 reflects the beam to the receiving mechanism 300. Subsequently, the grasping moving component 110 drives the optical device 30 to move to the optical device 20, and cooperates with the grasping component 140 to release the optical device 30 to its installation position in the optical device 20. In this way, by cooperating with the transmitting mechanism 200, the receiving mechanism 300, and the grasping adjustment component 130 to adjust the angle of the optical device 30, the angle of the optical device 30 is ensured to meet the requirements, so that the installation accuracy of the optical device 30 meets the requirements, thereby ensuring that the output power and beam quality in the optical device 20 meet the standards.

[0038] For crawling mechanism 100: Please see Figure 1 , Figure 2 and Figure 3 In one embodiment, the gripping mechanism 100 further includes a support 150. The gripping moving component 110 is disposed on the support 150. The support 150 raises the gripping moving component 110 and other structures, facilitating the movement of the gripping mechanism 100 and preventing interference between the gripping mechanism 100 and the movements of other mechanisms.

[0039] In one embodiment, the gripping and moving assembly 110 includes a first gripping translational drive 111, a second gripping translational drive 112, and a gripping lifting drive 113. The first gripping translational drive 111 is connected to the second gripping translational drive 112 to drive the second gripping translational drive 112 to move along a first direction. The second gripping translational drive 112 is connected to the gripping lifting drive 113 to drive the gripping lifting drive 113 to move along a second direction. The gripping lifting drive 113 is connected to the gripping adjustment assembly 130 to drive the gripping adjustment assembly 130 to move along a third direction. Preferably, the first gripping translational drive 111, the second gripping translational drive 112, and the gripping lifting drive 113 are all electric cylinders or linear modules.

[0040] In one embodiment, the gripping adjustment assembly 130 includes a first gripping adjustment drive 131, a second gripping adjustment drive 132, and a third gripping adjustment drive 133. The gripping movement assembly 110 is connected to the first gripping adjustment drive 131, and the first gripping adjustment drive 131 is connected to the second gripping adjustment drive 132 to drive the second gripping adjustment drive 132 to rotate about a third-direction axis. The second gripping adjustment drive 132 is connected to the third gripping adjustment drive 133 to drive the third gripping adjustment drive 133 to rotate about a first-direction axis. The third gripping adjustment drive 133 is connected to the gripping assembly 140 to drive the gripping assembly 140 to rotate about a second-direction axis.

[0041] It should be noted that the third direction is vertical, and the first gripping adjustment drive 131, the second gripping adjustment drive 132, and the third gripping adjustment drive 133 are arranged sequentially from top to bottom. Therefore, a gripping adjustment mounting base 134 and a first base 135 can be provided. The first base 135 is rotatably connected to the gripping adjustment mounting base 134 about the third direction axis. The first gripping adjustment drive 131 is a motor and is connected to the first base 135 through a gear or synchronous belt structure to drive the first base 135 to rotate.

[0042] The second gripping adjustment drive 132 and the third gripping adjustment drive 133 are used to drive their target object to rotate around a horizontal axis. Therefore, a second seat 136 and a third seat 137 are sequentially arranged below the first seat 135, and the gripping assembly 140 is disposed on the third seat 137. The lower surfaces of both the first seat 135 and the second seat 136 are arc-shaped, and the central axis of the arc-shaped lower surface of the first seat 135 extends along a first direction, while the central axis of the arc-shaped lower surface of the second seat 136 extends along a second direction. The upper surface of the second seat 136 matches the arc-shaped lower surface of the first seat 135. The second gripping adjustment drive 132 is disposed on the first seat 135 and can drive the second seat 136 to move along the lower surface of the first seat 135, thereby driving the second seat 136 to rotate around the axis in the first direction. Similarly, the upper surface of the third seat 137 matches the arc-shaped lower surface of the second seat 136. The third gripping adjustment drive 133 is disposed on the second seat 136 and can drive the third seat 137 to move against the lower surface of the second seat 136, thereby driving the third seat 137 to rotate around the axis in the second direction via the second gripping adjustment drive 132. Based on this, the second gripping adjustment drive 132 and the third gripping adjustment drive 133 are preferably electric cylinders to ensure adjustment accuracy.

[0043] In one embodiment, the gripping mechanism 100 includes two sets of gripping adjustment components 130 and two sets of gripping components 140. The two sets of gripping adjustment components 130 include a first gripping adjustment component 130 and a second gripping adjustment component 140, and the two sets of gripping components 140 include a first gripping component 141 and a second gripping component 142. The first gripping adjustment component 130 is connected to the first gripping component 141, and the second gripping adjustment component 130 is connected to the second gripping component 142. The first gripping component 141 and the second gripping component 142 are capable of gripping different optical devices 30. Specifically... Figure 2 In the illustrated embodiment, the first gripping component 141 is capable of gripping the PBS, and the second gripping component 142 is capable of gripping the reflector. Thus, different optical components 30 in the optical device 20 can be installed using this optical path coupling device, improving its applicability.

[0044] It should be noted that, in this embodiment, the gripping and moving component 110 includes two gripping lifting drive members 113, namely a first gripping lifting drive member 113 and a second gripping lifting drive member 113. The gripping and moving component 110 also includes a gripping translation seat 114. The second gripping translation drive member 112 is connected to the gripping translation seat 114 to drive the gripping translation seat 114 to move along a second direction. Both the first gripping lifting drive member 113 and the second gripping lifting drive member 113 are disposed on the gripping translation seat 114, and the first gripping lifting drive member 113 is connected to the first gripping adjustment component 130 to drive the first gripping adjustment component 130 to move along a third direction. The second gripping lifting drive member 113 is connected to the detection component 120 and the second gripping adjustment component 130 to drive the detection component 120 and the second gripping adjustment component 130 to move along a third direction. Thus, the first gripping component 141 and the second gripping component 142 can be raised and lowered independently. When one of them grips the optical device 30, the other can rise first to avoid obstruction. In addition, the first gripping adjustment component 130 and the second gripping adjustment component 130 have the same structure, which will not be described in detail here.

[0045] In one embodiment, the first gripping component 141 includes a gripping mounting base 143, a clamping module 144, an adsorption module 145, and a curing module 146. The first gripping adjustment component 130 is connected to the gripping mounting base 143. The clamping module 144, the adsorption module 145, and the curing module 146 are all disposed on the gripping mounting base 143. The clamping module 144 can clamp and position the optical device 30. The adsorption module 145 can adsorb and fix the optical device 30 clamped by the clamping module 144. The curing module 146 can cure the adhesive bonding the optical device 30.

[0046] In practical applications, the clamping module 144 includes a clamping drive unit 1441 and two grippers 1442. The clamping drive unit 1441 is disposed on the gripping mounting base 143 and is connected to the two grippers 1442 to drive the two grippers 1442 to move closer and further apart. When the two grippers 1442 move closer together, they can clamp and position the optical device 30; when they move further apart, they can release the optical device 30. Specifically, when the first gripping component 141 is used to grip the PBS, the positions where the two grippers 1442 grip the PBS are both formed with right-angle portions 1443, and the right-angle portions 1443 of the two grippers 1442 can grip the diagonal of the same side surface of the PBS, thereby realizing the clamping and positioning of the PBS by the two grippers 1442.

[0047] In one embodiment, the structure of the second gripping component 142 is partially the same as that of the first gripping component 141. The second gripping component 142 also includes a gripping mounting base 143, an adsorption module 145, and a curing module 146. The adsorption module 145 is used to adsorb and grip the optical device 30, and the curing module 146 can cure the adhesive bonding the optical device 30.

[0048] It should be noted that the gripping mounting base 143 and curing module 146 in the first gripping assembly 141 and the second gripping assembly 142 are the same. The curing module 146 can be a UV lamp, and the adhesive used to bond the optical device 30 is UV adhesive. Furthermore, in the first gripping assembly 141, the optical device 30 is positioned by the clamping module 144, so the adsorption module 145 can only have one adsorption plane. This adsorption plane can adsorb the top surface of the PBS, while the two grippers 1442 in the clamping module 144 can clamp the diagonal of the top surface of the PBS. The adsorption module 145 in the second gripping assembly 142 typically also needs to position the optical device 30, therefore it includes two adsorption planes. These two adsorption planes are connected to each other and perpendicular to each other, respectively adsorbing two adjacent sides of the optical device 30, thereby achieving adsorption, fixation, and positioning of the optical device 30. In addition, the adsorption modules 145 in both the first gripping assembly 141 and the second gripping assembly 142 are connected to a negative pressure module (e.g., a vacuum pump) via pipelines. This is a conventional method and will not be elaborated upon here.

[0049] In one embodiment, the gripping mechanism 100 further includes a dispensing assembly 160. The gripping and moving assembly 110 is also connected to the dispensing assembly 160 to drive the dispensing assembly 160 closer to the optical device 20 and dispensing adhesive onto the optical device 20. Therefore, in this embodiment, after the detection assembly 120 detects the mounting position on the optical device 20, adhesive can be dispensed at the mounting position of the optical device 20 via the dispensing assembly 160 before the optical device 30 is installed. In other embodiments, adhesive can also be dispensed onto the optical device 30 via other devices, or adhesive can be dispensed at the mounting position of the optical device 20 in advance via other devices.

[0050] In practical applications, the dispensing assembly 160 includes a dispensing lifting drive 161 and a dispensing head 162. The dispensing lifting drive 161 is connected to a second gripping lifting drive 113 to move along a third direction under the action of the second gripping lifting drive 113. Simultaneously, the dispensing lifting drive 161 is also connected to the dispensing head 162 to drive the dispensing head 162 to move along a third direction. Thus, in some cases, if the dispensing head 162 has not reached the dispensing position and the second gripping assembly 142 cannot continue to descend, the dispensing lifting drive 161 can drive the dispensing head 162 to continue descending to the dispensing position to complete the dispensing. Furthermore, the dispensing head 162 is connected to an adhesive supply module via a pipeline, and the adhesive supply module supplies adhesive to the dispensing head 162, allowing the dispensing head 162 to perform the dispensing action. Optionally, the dispensing lifting drive 161 is a cylinder.

[0051] In one embodiment, the detection component 120 includes a detection camera. The detection camera is connected to the second gripping lifting drive 113, and the detection camera can take pictures at a high height to simultaneously acquire position information of the optical device 20 and the optical device 30, thereby facilitating the gripping moving component 110, the gripping adjustment component 130, and the gripping component 140 to perform corresponding actions based on the position information.

[0052] It is understood that, in this embodiment, the optical path coupling device also includes a control module. The control module is connected to the electrical components in each mechanism and assembly to achieve automated operation of the optical path coupling device.

[0053] For transmitting mechanism 200 and receiving mechanism 300: Please see Figure 1 , Figure 4 and Figure 5 In one embodiment, the transmitting mechanism 200 includes a transmitting component 210 capable of emitting a light beam along a first direction. Simultaneously, the receiving mechanism 300 includes a receiving component 310 capable of receiving a light beam transmitted along a second direction.

[0054] In one embodiment, the emitting assembly 210 includes an emitting mount 211, a laser 212, a deflection drive 213, and a deflection reflector 214. Both the laser 212 and the deflection drive 213 are disposed on the emitting mount 211. The laser 212 is capable of emitting a light beam that propagates in a third direction. The deflection drive 213 is connected to the deflection reflector 214 to drive the deflection reflector 214 to rotate around the light beam emitted by the laser 212, and the deflection reflector 214 is capable of deflecting the light beam emitted by the laser 212 into a first direction.

[0055] Specifically Figure 3In the illustrated embodiment, the laser 212 emits red light downwards, and the reflector can deflect the vertical red light into a horizontal direction. Simultaneously, since the reflector can rotate around the vertical red light, it can deflect the red light into any horizontal direction, i.e., it can deflect the red light into a first direction.

[0056] It should be noted that, with Figure 3 In the first direction, the leftward direction is the positive direction, and the rightward direction is the negative direction. When adjusting the angle of the optical device 30 with its reflective surface facing the positive direction, the light beam reflected by the reflector should be transmitted in the negative direction to be emitted to the reflective surface of the optical device 30 and reflected by the reflective surface to the receiving assembly 310. Conversely, the light beam reflected by the reflector should be transmitted in the positive direction.

[0057] In one embodiment, the receiving component 310 includes a receiving mounting base 311, a spot camera 312, and a focusing lens 313. The spot camera 312 is disposed on the receiving mounting base 311, and the focusing lens 313 is connected to the spot camera 312. The focusing lens 313 can focus the light beam transmitted along the second direction onto the sensor center of the spot camera 312, and the spot is located at the center of the field of view in the camera display program interface. As described above, when the optical device 30 is used for beam deflection (acting as light reflection), as long as its reflecting surface is located on the beam path, a certain deviation in position (within the error range) will not affect the function of the optical device 30. However, if the angle of the optical device 30 is deviated, it will affect the beam deflection angle, thereby affecting the power and beam quality.

[0058] When adjusting the angle of the optical device 30, if there is a deviation in the angle of the optical device 30, it will cause the light spot to deviate from the center of the field of view. The greater the angle deviation, the more the light spot deviates. Therefore, the angle of the optical device 30 can be adjusted based on the deviation data of the light spot. Specifically: first, real-time data feedback from the recording program of the light spot camera 312 is obtained, and the adjustment component 130 adjusts the angle of the optical device 30 according to the feedback data until the light spot falls within the allowable deviation range of the center of the field of view or close to the center of the field of view. At this point, it can be determined that the angle adjustment of the optical device 30 has reached the set value and meets the requirements of the optical path.

[0059] It needs further explanation that if a small positional deviation causes the spot camera 312 to fail to receive the beam information that has reached the target, then the angle of the optical device 30 needs to be adjusted, that is, the positional deviation is compensated for by angle adjustment. This may cause the optical device 30, which was originally at the target angle, to be adjusted to an angle deviation, resulting in a decrease in the angle adjustment accuracy of the optical device 30, which affects the laser power and beam quality of the optical device 20.

[0060] In embodiment 1, the transmitting mechanism 200 further includes an optical path adjustment component 220. The optical path adjustment component 220 can drive the transmitting component 210 to rotate around the axes of the second and third directions to adjust the beam direction of the transmitting component 210, ensuring that the beam direction of the transmitting component 210 is transmitted along the first direction during use, or that the transmitting component 210 can be matched with the receiving component 310.

[0061] Specifically, if the incident light beam received by the optical device 30 in the optical equipment 20 is perpendicular to its required reflected light beam, then the light beam emitted by the transmitting component 210 and the light beam that the receiving component 310 can receive also need to be perpendicular. For example, in the above embodiment, the transmitting component 210 emits a light beam along a first direction, and the receiving component 310 can receive a light beam transmitted in a second direction. In other embodiments, if there is a certain deviation in the installation angle of the receiving component 310, the transmitting component 210 also needs to be adjusted accordingly to ensure that the light beam emitted by the transmitting component 210 and the light beam that the receiving component 310 can receive are perpendicular to each other. Therefore, the emission angle of the transmitting component 210 can be adjusted by the optical path adjustment component 220.

[0062] It should be noted that the specific structure of the optical path adjustment component 220 can be referred to the grasping adjustment component 130 in the above embodiments. Based on the structural description of the grasping adjustment component, those skilled in the art can conceive of the specific structure of the optical path adjustment component 220. Therefore, the specific structure of the optical path adjustment component 220 will not be elaborated here.

[0063] In embodiment 2, the receiving mechanism 300 further includes an optical path adjustment component 220. The optical path adjustment component 220 is connected to the receiving component 310 to drive the receiving component 310 to rotate about axes in a first direction and a third direction.

[0064] In embodiment 3, both the transmitting mechanism 200 and the receiving mechanism 300 include an optical path adjustment component 220. The optical path adjustment component 220 in the transmitting mechanism 200 can drive the transmitting component 210 to rotate about axes in a second direction and a third direction. The optical path adjustment component 220 in the receiving mechanism 300 can drive the receiving component 310 to rotate about axes in a first direction and a third direction.

[0065] In embodiment 4, both the transmitting mechanism 200 and the receiving mechanism 300 include an optical path adjustment component 220. The optical path adjustment component 220 in the transmitting mechanism 200 can drive the transmitting component 210 to rotate about an axis in a second direction. The optical path adjustment component 220 in the receiving mechanism 300 can drive the receiving component 310 to rotate about an axis in a first direction.

[0066] It can be determined that in Embodiment 4, the optical path adjustment component 220 is mainly used to adjust the horizontality of the optical path to ensure that the light beam emitted by the transmitting component 210 and the light beam received by the receiving component 310 are both horizontal beams. Similarly, in Embodiment 3, in addition to adjusting the horizontality of the optical path, the optical path adjustment component 220 can also adjust the angles of the transmitting component 210 and the receiving component 310 in the horizontal direction.

[0067] In embodiment a, the emitting mechanism 200 further includes a first optical path moving component 230. The optical path moving component is disposed on the large plate 10 and connected to the optical path adjusting component 220 or the emitting component 210 to drive the emitting component 210 to perform three-dimensional movement along a first direction, a second direction, and a third direction. Thus, the height and position of the emitting component 210 can be adjusted via the optical path moving component.

[0068] It should be noted that the specific structure of the optical path moving component can be referred to the grasping moving component 110 described above, and will not be repeated here. Furthermore, it should be explained that if the light beam emitted by the transmitting component 210 travels along the positive direction... In embodiment b, the receiving mechanism 300 further includes a second optical path moving component 320. The optical path moving component is connected to the optical path adjusting component 220 or the receiving component 310 to drive the receiving component 310 to move along a first direction and a third direction. It should be explained that, when the angle and position are accurate, the movement of the receiving component 310 along the second direction serves to move it closer to and further away from the optical device 30. Therefore, in this embodiment, the optical path moving component drives the receiving component 310 to move along the first direction and a third direction, thereby achieving adjustment of the height and position of the receiving component 310.

[0069] In embodiment c, both the transmitting mechanism 200 and the receiving mechanism 300 include optical path moving components, namely a first optical path moving component 230 and a second optical path moving component 320. The first optical path moving component 230 is connected to the optical path adjustment component 220 or the transmitting component 210 to drive the transmitting component 210 to perform three-dimensional movement along a first direction, a second direction, and a third direction. The second optical path moving component 320 is connected to the optical path adjustment component 220 or the receiving component 310 to drive the receiving component 310 to move along the first direction and the third direction.

[0070] It is understood that any of the above embodiments 1, 2, 3, and 4 can be combined with any of the embodiments a, b, and c, and no limitation is imposed here.

[0071] For bearing mechanism 400: Please also refer to Figure 1 and Figure 6In one embodiment, the carrying mechanism 400 includes a carrying moving component 410 and a platform 420. The carrying moving component 410 is disposed on the large plate 10 and connected to the platform 420 to drive the platform 420 to move along a first direction and a second direction to adjust the position of the platform 420. It is understood that when the platform 420 is located below the gripping mechanism 100, it may be inconvenient to automatically feed materials. Therefore, the platform 420 can be moved out, and after feeding, the platform 420 can be moved back below the gripping mechanism 100. In practical applications, the platform 420 is provided with a positioning structure 421. The positioning mechanism can position the optical device 20 and the optical component 30. At the same time, a negative pressure hole is also provided on the upper surface of the platform 420. The negative pressure hole is connected to a negative pressure module through a pipeline, thereby fixing the optical device 20 and the tray containing the optical component 30.

[0072] In one embodiment, the carrier mechanism 400 further includes a calibration component 430. The calibration component 430 is disposed on the stage 420, and the stage 420 can pass through a calibration position during movement. When the stage 420 moves to the calibration position, the calibration component 430 can reflect the light beam emitted by the transmitting component 210 to the receiving component 310. In other words, the calibration component 430 can deflect the light beam transmitted along a first direction to be transmitted along a second direction. Therefore, it can be determined that even if there is a deviation in the position or angle of the transmitting component 210 and the receiving component 310, the positions of both can be calibrated by the calibration component 430. Thus, after long-term use of the optical path coupling device, the position and angle of the transmitting component 210 and the receiving component 310 can be calibrated by the calibration component 430, improving the long-term reliability of the optical path coupling device.

[0073] Similarly, when calibrating the optical path, real-time data feedback from the recording program of the spot camera 312 can be obtained first. Then, the position or angle of the transmitting component 210 and / or the receiving component 310 can be adjusted according to the feedback data until the spot falls within the allowable deviation range of the center of the field of view or close to the center of the field of view. At this time, it can be determined that the transmitting component 210, the calibration component 430, and the receiving component 310 are matched. In this embodiment, the calibration component 430 includes a first reflector 431 and a second reflector 432. The first reflector 431 can reflect the beam transmitted in the positive direction, and the second reflector 432 can reflect the beam transmitted in the negative direction.

[0074] It should be noted that the structure of the carrier moving component 410 can be referenced from the grasping moving component 110, so it will not be described in detail here.

[0075] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 The working process of the optical path coupling device in the above embodiments is described as follows: Before coupling, the positions of the transmitting component 210 and the receiving component 310 are determined and fixed according to requirements. First, the laser module and the tray containing the PBS and reflector are placed on the stage 420. A detection camera captures images of the laser module and tray on the stage 420 to determine the position information of the laser module, its mounting position, the PBS, and the reflector. Next, based on the position information, the gripping moving component 110 and the gripping component 140 are controlled to grip one of the PBS or the reflector and move it into the beam path of the transmitting component 210. The gripping adjustment component 130 adjusts the angle of the PBS or the reflector until the reflected beam is transmitted to the receiving component 310 along the second direction. The gripping adjustment component 130 remains stationary, and the gripping moving component 110 drives the dispensing component 160 to move and dispense adhesive at the mounting position of the laser module. Then, the gripping component 140 is driven to move the PBS or the reflector to the laser module and release it to the mounting position. The adhesive is then cured by the curing module 146, completing the installation of the PBS or the reflector. Next, repeat the steps to complete the installation of the PBS and the other mirror.

[0076] After long-term operation, if it is necessary to adjust the angle of the transmitting component 210 and / or the receiving component 310, the stage 420 can be moved to the calibration position by the carrier moving component 410, and then the angle of the transmitting component 210 and / or the receiving component 310 can be adjusted by the optical path adjustment component 220 until the beam emitted by the transmitting component 210 is reflected by the calibration component 430 and enters the receiving component 310.

[0077] In some implementation scenarios, if it is necessary to couple optical devices 30 of different specifications or types, the position, height, and angle of the transmitting component 210 and the receiving component 310 can be adjusted by the optical path moving component and the optical path adjusting component 220. At the same time, if the orientation of the reflective surface of the PBS or the reflector changes, the deflecting reflector 214 can be rotated by the deflection drive 213 to adjust the beam transmission direction.

[0078] In summary, the optical path coupling device provided in this application has at least the following advantages: 1. The angle of the optical device 30 is adjusted by the cooperation of the transmitting mechanism 200, the receiving mechanism 300 and the grasping and adjusting component 130 to ensure that the angle of the optical device 30 meets the requirements, so that the installation accuracy of the optical device 30 meets the requirements, and the output power and beam quality in the optical equipment 20 meet the standards.

[0079] 2. The calibration component 430 can calibrate the position and angle of the transmitting component 210 and the receiving component 310, thereby improving the long-term reliability of the optical path coupling device.

[0080] 3. The beam in the emitting component 210 can be adjusted in emission direction by the deflection drive 213 and the deflection reflector 214 to suit the adjustment of different optical devices 30.

[0081] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
