[0044] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0045] In optical communication products, the folded optical device 2000 (such as a collimator) is usually composed of a tube shell 210 and a lens 220. One end of the tube shell 210 is closed and fixed with an optical fiber 211, and the other end is internally provided with the lens 220. Since the input optical fiber and the output optical fiber of the optical fiber 211 are located on the same side of the tube shell 210, the overall structure of the device is more compact, and therefore it is also widely used in various miniaturized optical modules. Then, due to the compactness of its own structure, it is more difficult to manufacture the folded optical device 2000 in the production process, and the existing technology requires manual position fine adjustment of the tube shell 210 and the lens 220 in assembly and fixation, which further leads to a series of problems such as unstable performance of the finished product of the folded device and poor production efficiency.

[0046] In order to solve the above problems, the embodiments of the present application provide a coupling device 1000 applied to manufacture a folded optical device 2000, such as Figure 1 and Figure 2As shown, the coupling device 1000 includes a coupling mechanism 10, a light detection mechanism 20, and a dispensing assembly 30. The coupling mechanism 10 includes a lens moving mechanism 11 and a housing moving mechanism 12. The lens moving mechanism 11 includes a first clamping member 111 and a first moving component 112. The first clamping member 111 is connected to the first moving component 112 and is used to fix the lens 220. The housing moving mechanism 12 includes a second clamping member 121 and a second moving component 122. The second moving component 122 is located at the first moving component 112 in a first direction (e.g., ...). Figure 1 On one side of the first moving assembly 121 (as shown in the X direction), the second clamping member 121 is connected to the second moving assembly 122. The second clamping member 121 is used to fix the tube shell 210. The first moving assembly 112 and the second moving assembly 122 cooperate to make the lens 220 on the first clamping member 111 fit into the tube shell 210 on the second clamping member 121. The light detection mechanism 20 includes a light tester 21 and a reflection assembly 22. The coupling mechanism 10 is disposed between the light tester 21 and the reflection assembly 22. The light tester 21 is electrically connected to the first moving assembly 122. The coupling device 1000 of this application solves the problem of low production efficiency and reduced finished product performance caused by manual adjustment and assembly in the manufacturing process of foldable optical devices 2000. The coupling device 1000 of this application enables automated assembly of foldable optical devices 2000, such as collimators, improving production efficiency while ensuring finished product performance. The coupling device 1000 of this application enables automated assembly of foldable optical devices 2000, such as collimators, improving production efficiency while ensuring finished product performance.

[0047] Specifically, the first clamping piece 111 is used for fixing the lens 220, the second clamping piece 121 is used for fixing the ferrule 210, the first moving assembly 112 and the second moving assembly 122 are cooperatively moved to automatically pre-socket the lens 220 on the first clamping piece 111 into the ferrule 210 on the second clamping piece 121, and then the optical tester 21 inputs the light beam to the optical fiber 211 of the ferrule 210, the light beam passes through the lens 220 and is reflected back to the optical fiber 211 by the reflector 221 and then back to the optical tester 21, the optical tester 21 can test the coupling and drive the first moving assembly 112 and the second moving assembly 122 to finely adjust the relative position of the lens 220 and the ferrule 210 at the optical fiber 211 according to the test result, so that the coupling efficiency reaches the maximum, and finally the dispensing head 31 is used to dispense and solidify the connection between the lens 220 and the ferrule 210 to complete the assembly. As can be seen, the coupling device 1000 can realize automatic alignment and improve the coupling efficiency when the folded optical device 2000 is manufactured, so as to ensure the performance of the folded optical device 2000, and also can reduce the operation difficulty of workers and effectively improve the production efficiency.

[0048] In the present application, the optical tester 21 can be a double-channel optical power meter, which can detect the coupling of the input optical fiber and the output optical fiber in the optical fiber 211.

[0049] In the present application, the coupling device 1000 further comprises a machine table 90, the coupling mechanism 10, the light detection mechanism 20 and the dispensing assembly 30 are all arranged on the machine table 90, the machine table 90 can provide the same installation reference for the coupling mechanism 10, the light detection mechanism 20 and the dispensing assembly 30, which is more conducive to the assembly of the optical device and the transfer of the whole coupling device 1000. Further, the machine table 90 is further provided with a machine cover to protect the internal mechanism and avoid the collision caused by the direct contact between the personnel and the internal mechanism during the operation of the device.

[0050] Referring to Figure 3 - Figure 5In an embodiment, the first clamping member 111 comprises a first base 1111, a first pressing plate 1112, and a first elastic member 1113. The first base 1111 is arranged at the first moving assembly 112, and the first base 1111 is provided with a first profiling groove 1111a for placing the lens 220. The first pressing plate 1112 comprises a force applying portion 1112a, a rotating portion 1112b, and a pressing portion 1112c. The pressing portion 1112c is connected to the rotating portion 1112b and is arranged opposite to the first profiling groove 1111a. The rotating portion 1112b is rotationally connected to the first base 1111. The force applying portion 1112a is arranged at a side of the rotating portion 1112b away from the pressing portion 1112c. The first elastic member 1113 is clamped between the force applying portion 1112a and the base, so that the pressing portion 1112c can press the lens 220 in the first profiling groove 1111a. In this way, the first clamping member 111 can firmly fix the lens 220, which is conducive to the accurate assembly of the lens 220 and the tube shell 210, and also facilitates manual feeding of the operator, reduces feeding time, and improves production efficiency.

[0051] Specifically, the first elastic member 1113 is a spring. The spring provides an elastic force to the force applying portion 1112a, so that the force applying portion 1112a always has a movement tendency of moving away from the first base 1111. Due to the limitation of the rotating portion 1112b, the force applying portion 1112a swings upward after being subjected to the elastic force, and in turn drives the pressing portion 1112c to press downward at the position of the first profiling groove 1111a of the first base 1111. Thus, the lens 220 placed in the first profiling groove 1111a is clamped and fixed. When feeding is needed, the operator can press the force applying portion 1112a. At this time, the first elastic member 1113 is compressed and stored, the pressing portion 1112c is lifted, and the first clamping member 111 is unlocked from the lens 220. After re-feeding, the force applying portion 1112a is not subjected to force, and at this time, the first elastic member 1113 can release energy to reset the pressing portion 1112c to press downward again, which reduces the operation steps and achieves the purpose of rapid feeding.

[0052] The first profiling groove 1111a can be freely adjusted according to the shape of the lens 220, which is not limited herein. For example, in the present application, the lens 220 is cylindrical, and the first profiling groove 1111a is a V-shaped groove.

[0053] Similarly, referring to Figure 7 and Figure 8The second clamping member 121 includes a second base 1211, a second pressure plate 1212, and a second elastic member 1213. The second base 1211 is mounted on the second moving assembly 122 and has a second contouring groove for placing the lens 220. The second pressure plate 1212 includes a pressing part, a rotating part, and a pressing part. The pressing part is connected to the rotating part and is disposed opposite to the second contouring groove. The rotating part is rotatably connected to the second base 1211. The pressing part is disposed on the side of the rotating part away from the pressing part. The second elastic member 1213 is clamped between the pressing part and the second base 1211 so that the pressing part can press the tube shell 210 into the second contouring groove. The technical effect of the second clamping member 121 is the same as that of the first clamping member 111, and will not be repeated here.

[0054] It should be noted that, since one end of the lens 220 needs to be inserted into the other end of the tube shell 210, and the other end of the lens 220 needs to be connected to the reflective device 221, and the optical fiber 211 at one end of the tube shell 210 also needs to be connected to the optical tester 21, when the first clamping member 111 and the second clamping member 121 clamp the material in the manner set in the above embodiment, the shape setting of the pressing part 1112c and the corresponding position of the first base 1111 and the pressing part 1112c can not only fix the lens 220 or the tube shell 210, but also allow their two ends to be exposed to the outside to meet the required production needs. The structural design is simpler and more reasonable.

[0055] Reference Figure 7 and Figure 8 In one embodiment, the first moving assembly 112 includes a first horizontal drive 1121, a second horizontal drive 1122, a first lifting drive 1123, a first rotary slide 1124, and a second rotary slide 1125, all connected to the first clamping member 111. The first horizontal drive 1121 drives the first clamping member 111 to move along a first direction; the second horizontal drive 1122 drives the first clamping member 111 to move along a second direction (e.g., ...). Figure 1 The first lifting drive 1123 is used to drive the first clamping member 111 to move along a third direction (as shown in the Y direction); Figure 1 The first rotating slide 1124 (as shown in the Z direction) is used to adjust the pitch angle of the first clamping member 111, and the second rotating slide 1125 is used to adjust the yaw angle of the first clamping member 111. The first, second, and third directions are perpendicular to each other. With this configuration, the first moving component 112 can adjust the position of the first clamping member 111 in five dimensions, allowing the lens 220 to be more accurately fitted onto the housing 210. Furthermore, by fine-tuning the position of the first clamping member 111, the assembly accuracy is improved, enabling the foldable optical device 2000 to achieve maximum coupling efficiency.

[0056] Specifically, the second rotary slide 1125, the first rotary slide 1124, the first lifting drive 1123, the second horizontal drive 1122, and the first horizontal drive 1121 are sequentially connected from top to bottom, and the first clamping member 111 is installed at the second rotary slide 1125. The first rotary slide 1124 and the second rotary slide 1125 can both be electric angular slides or other angle rotation devices, and the first horizontal drive 1121, the second horizontal drive 1122, and the first lifting drive 1123 can be linear modules, electric cylinders, or other linear drive motion modules.

[0057] It is understood that the connection order between the first horizontal drive component 1121, the second horizontal drive component 1122, the first lifting drive component 1123, the first rotary slide 1124, and the second rotary slide 1125 can be freely adjusted by designers in the art according to the actual application scenario, and is not limited here.

[0058] Similarly, the second moving assembly 122 includes a third horizontal drive 1221, a fourth horizontal drive 1222, a second lifting drive 1223, a third rotary slide 1224, and a fourth rotary slide 1225, all connected to the second clamping member 121. The third horizontal drive 1221 drives the second clamping member 121 to move along a first direction; the fourth horizontal drive 1222 drives the second clamping member 121 to move along a second direction; the second lifting drive 1223 drives the second clamping member 121 to move along a third direction; the third rotary slide 1224 adjusts the pitch angle of the second clamping member 121; and the fourth rotary slide 1225 adjusts the yaw angle of the second clamping member 121. The first, second, and third directions are perpendicular to each other. The technical effect of the second moving assembly 122 is consistent with that of the first moving assembly 112, and will not be repeated here.

[0059] It is worth mentioning that, since the second moving component 122 and the first moving component 112 can respectively adjust the position of the tube shell 210 and the lens 220 in five dimensions, when the two work together, they can be aligned and assembled more quickly and fine-tuned after assembly, further improving production efficiency.

[0060] Similarly, refer to Figure 2 The reflective assembly 22 also includes a fourth moving assembly 222, which is used to mount the reflective device 221. Its configuration is the same as that of the first moving assembly 112 and the second moving assembly 122, and will not be repeated here. Thus, before the coupling device 1000 operates, the operator can use the fourth moving assembly 222 to perform preliminary alignment and positioning adjustments between the reflective device 221 and the coupling mechanism 10, thereby reducing the movement distance of the coupling mechanism 10 during assembly and making assembly more efficient.

[0061] Referring to Figure 3 Further, the reflection assembly 22 further comprises a third clamping member 223 connected to the fourth moving assembly 222, and the third clamping member 223 is used to fix the reflection device 221. The third clamping member 223 is arranged in the same way as the first clamping member 111, and thus will not be repeated here.

[0062] It should be noted that the reflection device 221 refers to an optical device capable of reflecting light, such as a prism, a mirror, etc.

[0063] Referring to Figure 6 In an embodiment, the lens moving mechanism 11 further comprises a first positioning seat 113 arranged on the first moving assembly 112, and the first clamping member 111 is detachably connected to the first positioning seat 113. In this way, the operator can directly take out the first clamping member 111 to the outside of the coupling device 1000 for reloading when the device needs to be reloaded after completing a single work flow, which is more convenient and efficient than the embodiment in which the operator's body is inserted into the device for reloading. In addition, the first positioning seat 113 can also play a positioning role when the first clamping member 111 is installed, ensuring that the first clamping member 111 can still be in the pre-set installation position after being detached and installed to the first positioning seat 113, thereby avoiding affecting the production assembly alignment process.

[0064] The first clamping member 111 can be detachably connected to the first positioning seat 113 in many ways. In an embodiment, the first positioning seat 113 is provided with a positioning groove 1131, and the groove wall of the positioning groove 1131 is provided with a buckle. The first clamping member 111 is provided with a clamping groove, and the first clamping member 111 is placed in the positioning groove 1131, and the buckle and the clamping groove are buckled to achieve detachable connection.

[0065] In another embodiment, the first positioning seat 113 is provided with a positioning groove 1131, and the groove wall of the positioning groove 1131 is provided with a magnet 1132. The first clamping member 111 is provided with a metal part, and the first clamping member 111 is placed in the positioning groove 1131, and the metal part is magnetically connected to the magnet 1132. In this way, the positioning groove 1131 is installed and detached by magnetic connection, which is more convenient and efficient, and can effectively save time.

[0066] Preferably, the magnet 1132 is provided with a plurality of magnets 1132, which are uniformly distributed at the side groove walls and the bottom groove wall of the positioning groove 1131, so as to improve the connection stability of the first clamping member 111 and ensure that the first clamping member 111 will not be offset during the movement of the coupling device 1000.

[0067] Similarly, the tube shell moving mechanism 12 further comprises a second positioning seat, which is arranged on the second moving assembly 122, and the second clamping piece 121 is detachably connected to the second positioning seat.

[0068] Referring to Figure 1 , Figure 2 and Figure 9 In an embodiment, the coupling device 1000 further comprises a photographing positioning mechanism 40, which comprises a horizontal camera assembly 41 and a vertical camera assembly 42. The vertical camera assembly 42 is arranged at the top of the coupling mechanism 10, and the horizontal camera assembly 41 is arranged beside the coupling mechanism 10. The first moving assembly 112 and the second moving assembly 122 are electrically connected to the vertical camera assembly 42 and the horizontal camera assembly 41, so as to adjust the relative position of the first clamping piece 111 and the second clamping piece 121 according to the identification information of the horizontal camera assembly 41 and the vertical camera assembly 42. In this way, the horizontal camera assembly 41 and the vertical camera assembly 42 can cooperate to more accurately identify the center position of the lens 220 and the tube shell 210, and realize accurate fitting of the lens 220 and the tube shell 210.

[0069] Specifically, the horizontal camera assembly 41 comprises a first high-definition observation camera 411 and a first intelligent identification camera 412 arranged at intervals in a first direction. The first high-definition observation camera 411 and the first intelligent identification camera 412 are arranged on a fifth horizontal driving member 413, which is used to drive the first high-definition observation camera 411 and the first intelligent identification camera 412 to alternately switch positions at the coupling mechanism 10. The fifth horizontal driving member 413 can be a linear module, an electric cylinder or other linear driving motion units. The arrangement of the first high-definition observation camera 411 and the first intelligent identification camera 412 is conducive to more clearly capturing the position image information of the lens 220 and the tube shell 210. Similarly, the vertical camera assembly 42 comprises a second high-definition observation camera 421 and a second intelligent identification camera 422.

[0071] Referring to Figure 9In an embodiment, the coupling device 1000 further comprises a third moving assembly 50 and a curing assembly 60, the curing assembly 60 comprises a UV light source head 61, the UV light source head 61 is arranged on the top of the coupling mechanism 10, the curing assembly 60, the dispensing assembly 30 and the vertical camera assembly 42 are sequentially connected to the third moving assembly 50 in the first direction, and the third moving assembly 50 is used to drive the three to be alternately transferred to the coupling mechanism 10. In this way, the UV light source head 61 of the curing assembly 60 can cure the glued folded optical device 2000 after dispensing to improve production efficiency. Moreover, by arranging a third moving assembly 50 to drive the three to be alternately transferred to the coupling mechanism 10, the photographing positioning, dispensing and curing are realized in the same reference movement path, which is conducive to the accurate alignment of each assembly. Since only one third moving assembly 50 is arranged, compared with the embodiment in which the curing assembly 60, the dispensing assembly 30 and the vertical camera assembly 42 are respectively provided with a driving mechanism, the number of mechanisms arranged is less, which is more conducive to the internal component space layout of the coupling device 1000, and can also save production cost.

[0072] Specifically, the third moving assembly 50 is an XYZ multi-axis moving module 51, which can drive the curing assembly 60, the dispensing assembly 30 and the vertical camera assembly 42 to move in the first direction, the second direction and the third direction respectively, that is, the UV light source head 61, the dispensing head 31 and the vertical camera assembly 42 can move forward, backward, left and right and ascend and descend under the driving of the XYZ multi-axis moving module 51, avoiding motion interference, realizing more accurate photographing positioning, dispensing and curing functions.

After the device is glued and cured, the third lifting driving member 522 can drive the unlocking member 521 to press the pressing part of the first clamping member 111, so that the lens 220 on the first clamping member 111 is unlocked, and the finished optical device is fixed at the second clamping member 121. When the operator takes the material, only the second clamping member 121 needs to be taken and placed. Compared with the embodiment in which the first clamping member 111 and the second clamping member 121 are taken out together with the finished optical device, only the second clamping member 121 needs to be taken out, and the discharging operation is more convenient and fast, and the risk of damage to the finished optical device due to improper force during the taking-out process can be eliminated. Specifically, the third lifting driving member 522 can be a pneumatic cylinder or an electric cylinder.

[0075] In an embodiment, the curing assembly 60 is connected to the third lifting driving member 522, and the unlocking member 521 is located between the UV light source head 61 and the glue dispensing head 31. In this way, the relative position of the unlocking member 521 and the UV light source head 61 relative to the coupling assembly is switched by the third moving assembly 50, and one third lifting driving member 522 is used to drive the unlocking member 521 to press down and lift up, and the UV light source head 61 to lift up, which can further save production cost.

[0076] Referring to Figure 1 In an embodiment, the coupling device 1000 further comprises a cleaning mechanism 80, the cleaning mechanism 80 is arranged below the glue dispensing assembly 30, and the cleaning mechanism 80 is used to clean the glue dispensing head 31. In this way, the glue dispensing head 31 does not need to be manually cleaned, which is more time-saving and labor-saving, and the production efficiency is higher.

[0077] Specifically, the cleaning mechanism 80 comprises a cleaning belt, a transmission structure and a motor, the motor is connected to the transmission structure, the cleaning belt is arranged at the transmission structure, the motor can drive the cleaning belt to be belt-driven through the transmission structure, the glue dispensing head 31 is moved to the cleaning belt and contacts the cleaning belt, and the excess glue on the glue dispensing head 31 is removed by belt driving of the cleaning belt.

In this way, the optical fiber 211 comprises an input optical fiber and an output optical fiber, both of which are connected to the optical tester 21, when the input optical fiber and the output optical fiber are not connected to the optical tester 21, the fiber alignment assembly 70 can correct the end portions of the input optical fiber and the output optical fiber, so that they can be accurately coupled and connected to the optical tester 21, and ensure that the coupling test is normally carried out.

[0079] Specifically, when the optical fiber 211 is not connected and contacted with the optical tester 21, the operator can correct the end portions of the optical fiber 211 by turning up the upper mold base 72 and respectively placing and fixing the input optical fiber and the output optical fiber on the lower mold base 71, then flattening the upper mold base 72 and starting the fourth lifting drive 73, the fourth lifting drive 73 is an electric cylinder which can drive the elastic pressing rod 731 to abut against the upper mold base 72, so that the upper mold base 72 is elastically held on the input optical fiber and the output optical fiber. The arrangement of the elastic pressing rod 731 avoids damaging the optical fiber 211 during correction due to excessive pressing force, and has better reliability.
