Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to a device used for coupling optical devices. Background Art

[0002] With the rapid development of application fields such as big data, blockchain, cloud computing, the Internet of Things, and artificial intelligence, data traffic has exploded. Optical communication technology has gradually replaced traditional electrical signal communication in various industries with its unique advantages such as fast speed, high bandwidth, and low installation cost. In optical communication technology, optical modules are tools for realizing the mutual conversion of optical and electrical signals. They are one of the key components in optical communication equipment, and with the development of optical communication technology, the transmission rate of optical modules continues to increase. Some optical modules include optical transceiver components, which include optical receivers and optical transmitters. The optical receivers and optical transmitters are electrically connected to the circuit board through a flexible circuit board. The optical receiver and the optical transmitter are integrated with a variety of optical devices. With the advancement of optical communication technology, the types of optical devices are increasing, and the structure of optical devices is becoming more and more complex. The process of connecting different optical devices (including optical fibers, light sources, optical detectors, etc.) together to realize optical signal transmission is called optical device coupling.

[0003] During the coupling process, a clamping device is required to clamp the optical device. At present, the chuck of the traditional clamping device is mainly clamped by manually tightening the knob. It is necessary to ensure that the force of manually tightening the knob is consistent, but there are differences in the tightening force of different operators, which affects the efficiency and yield of the product. In addition, the traditional clamping device cannot adjust the angle after clamping the material, and can only rely on adjusting the angle before clamping, which is time-consuming and labor-intensive, and easily causes difficulties in rear-end coupling. In view of this, how to design a technology that is convenient for clamping optical devices and can accurately adjust the clamping angle of optical devices to facilitate rear-end coupling is a technical problem to be solved by the utility model.

[0060] In optical communication technology, optical signals are used as carriers of information for high-speed, long-term, and reliable information transmission. As a core component in the field of optical communication, the coupling effect between the optical components and the transmission path (optical fiber) in the optical module greatly affects the intensity and quality of the optical signal, thus becoming one of the key factors affecting information transmission.

[0061] There are two methods for achieving optical path coupling between optical components and transmission optical fibers in optical modules: active coupling and passive coupling.

[0062] The process of the active coupling method is: fix the laser as the light source on the PCB board, then control the laser to emit light, use the coupler to adjust the spatial position of the optical lens module used as a device to change the optical transmission path, and detect the light intensity coupled into the optical fiber through the module. When the light intensity emitted by the optical fiber reaches the maximum value, the lens position at this time is determined to be the optimal coupling position.

[0063] The process of the passive coupling method is: first fix the laser, then use two cameras to photograph the laser and the optical lens module respectively, transmit the images to the PC, adjust the position of the lens, and when the centers of the two images coincide, determine that the lens position at this time is the optimal coupling position.

[0064] Laser is an important component of optical devices (optical signal receiving and transmitting components). The laser is composed of multiple tube legs. In the processing of optical devices, laser coupling is an important link, and the stability and angle control of the laser during coupling directly determine the quality of the product.

[0065] In the first aspect, combined Figures 1 to 10 As shown, an embodiment of the present disclosure provides a device for coupling optical devices, which includes a Z-axis motion mechanism 2 and a clamping device 1. The clamping device 1 includes a mounting portion 11, a base 12, a rotating clamping assembly 13 and a rotating driving portion 14.

[0066] The mounting portion 11 is L-shaped and has a plurality of mounting holes formed thereon. Fasteners pass through the mounting holes to fix the mounting portion 11 on the Z-axis motion mechanism 2. In the present application, the Z-axis motion mechanism 2 can drive the entire clamping device 1 to move.

[0067] The Z-axis motion mechanism 2 is a mechanism capable of performing linear motion in the Z-axis direction, and is generally composed of a guide rail, a slider, and a transmission system. Among them, the guide rail is a basic component that supports and guides the movement of the slider, and the slider is a component responsible for bearing and transmitting the load and performing linear motion on the guide rail. The transmission system is used to drive the slider to perform linear motion on the guide rail, and common transmission systems include screw transmission and gear transmission. In this application, the specific structural form of the Z-axis motion mechanism 2 can be set according to actual needs, and is not limited here.

[0068] Combination Figure 1 As shown, the base 12 is a plate-shaped structure and is fixedly connected to one end of the mounting portion 11;

[0069] The rotating clamping assembly 13 includes a rotating part 131, a sliding part 132, a connecting part 133, a sliding driving part 134, a chuck 135 and a sleeve 136. The rotating part 131 is annular in structure to facilitate its rotation. An annular groove is formed on the base 12 at a position corresponding to the rotating part 131. The rotating part 131 is arranged in the annular groove. The rotating part 131 is rotatably connected to the base 12; the sliding driving part 134 is fixedly connected to the base 12 via the first bracket 18.

[0070] Specifically, the first bracket 18 is in a gate-shaped structure, and ear plates are respectively provided at both ends of the first bracket 18 . The sliding drive unit 134 is fixed to the top of the first bracket 18 , and the ear plates of the first bracket 18 are fixed to the base 12 .

[0071] The rotating clamping assembly 13 can rotate and clamp the optical device, and can move up and down driven by the Z-axis motion mechanism.

[0072] The rotation driving part 14 is fixedly disposed on the base 12 via the second bracket 19 and is drivingly connected to the rotating part 131 to drive the rotating part 131 to rotate relative to the base 12 ; wherein the second bracket 19 has a similar structure to the first bracket 18 .

[0073] In some embodiments of the present application, the rotation driving unit 14 includes a driving motor 141 .

[0074] In some embodiments of the present application, the driving motor 141 is connected to the rotating part 131 via a belt transmission.

[0075] Specifically, a first pulley 142 is provided on the output shaft of the driving motor 141, and a second pulley 1311 is provided on the rotating shaft of the rotating part 131. The first pulley 142 and the second pulley 1311 are connected by a belt. When the driving motor 141 rotates, the rotating part 131 can be driven to rotate by the belt.

[0076] In some other embodiments of the present application, the driving motor 141 and the rotating part 131 are driven by gear meshing.

[0077] Specifically, a gear is provided on the output shaft of the driving motor 141, and a sawtooth portion is provided on the outer wall surface of the rotating part 131. The gear and the sawtooth portion are meshed with each other. When the driving motor 141 rotates, the rotating part 131 can be driven to rotate through the meshing of the gear and the sawtooth portion.

[0078] Combination Figure 2 and Figure 3 The chuck 135 shown is fixedly arranged at the bottom of the rotating part 131. The chuck 135 is used to clamp the optical device 3. The chuck 135 has a conical structure and is elastic. The chuck 135 can be opened under the action of external force. After the external force is removed, the chuck 135 returns to its original state and closes. A slide groove is formed in the rotating part 131, and the sliding part 132 is arranged in the slide groove. The sliding part 132 is configured to be slidably connected with the rotating part 131, and the sliding part 132 rotates synchronously with the rotating part 131.

[0079] A sleeve 136 is provided at the bottom of the sliding portion 132. The sleeve 136 has a straight cylindrical structure and is sleeved on the outside of the chuck 135. Specifically, the sleeve 136 is sleeved outside the conical surface of the chuck 135. Since the inner diameter of the sleeve 136 remains unchanged, when the sleeve 136 moves up and down relative to the chuck 135, when the sleeve 136 does not contact the conical surface of the chuck 135, the chuck 135 is not subjected to force. At this time, the chuck 135 is in an open state. When the sleeve 136 contacts the conical surface of the chuck 135 and squeezes the conical surface of the chuck 135 toward the center of the chuck 135, the chuck 135 is in a clamped state.

[0080] One end of the connecting portion 133 is rotatably connected to the sliding portion 132 , and the other end of the connecting portion 133 is fixedly connected to the sliding driving portion 134 . The sliding driving portion 134 drives the sliding portion 132 to reciprocate relative to the rotating portion 131 through the connecting portion 133 to drive the sleeve 136 to open or close the chuck 135 .

[0081] Specifically, the clamping device 1 includes a mounting portion 11, a base 12, a rotating clamping assembly 13 and a rotating driving portion 14. The mounting portion 11 is used to fix the base 12 on the Z-axis motion mechanism 2 of the device for coupling optical devices. The rotating clamping assembly 13 includes a rotating portion 131, a sliding portion 132, a connecting portion 133, a sliding driving portion 134, a chuck 135 and a sleeve 136. The sliding portion 132 is slidably connected to the rotating portion 131 and can rotate synchronously with the rotating portion 131. A sleeve 136 is provided at the bottom of the sliding portion 132, and the sleeve 136 is sleeved on the chuck 135 at the bottom of the rotating portion 131. The sliding driving portion 134 drives the sliding portion 132 to slide back and forth relative to the rotating portion 131 through the connecting portion 133, thereby realizing the opening or closing of the chuck 135, so that the chuck 135 releases or clamps the optical device 3. At the same time, the force consistency of the chuck 135 clamping the optical device 3 is good.

[0082] At the same time, in the process of driving the rotating part 131 to rotate relative to the base 12, the rotating driving part is convenient for adjusting the angle of the optical device 3 clamped on the clamp 135, realizing precise control of the angle rotation, facilitating rear-end coupling, and being beneficial to improving operation efficiency and ensuring product yield; the present application can realize the two functions of rotation and clamping of the optical device 3, with high integration and low maintenance cost.

[0083] Combination Figure 4 and Figure 5 As shown in some embodiments of the present application, a clamping hole is provided at the center of the chuck 135, and the clamping hole is used to place the optical device 3. The chuck 135 includes a plurality of clamping petals 1351 arranged at intervals. The clamping petals 1351 are at a certain distance from the center line of the chuck 135. The clamping petals 1351 are elastic and can be deformed in a direction close to or away from the center line of the chuck 135. When the clamping petals 1351 move in a direction close to the center line of the chuck 135, the chuck 135 is in a clamping mode. When the clamping petals 1351 move in a direction away from the center line of the chuck 135, the chuck 135 is in an open mode.

[0084] Exemplarily, the clamp 135 includes 3 to 6 clamping petals 1351. Of course, the number of clamping petals 1351 can be set according to actual needs.

[0085] Combination Fig.10 As shown, in some embodiments of the present application, a first clamping groove 1352 is formed on the chuck 135, and a second clamping groove 1361 is formed on the sleeve 136 at a position corresponding to the first clamping groove 1352. The first clamping groove 1352 and the second clamping groove 1361 are configured to connect the pins on the optical device 3 to the power cord, thereby facilitating the chuck 135 to clamp the optical device.

[0086] Combination Figure 6As shown, in some embodiments of the present application, the axis of rotation of the rotating part 131 relative to the base 12 is the first axis; the axis of rotation of the sliding part 132 relative to the connecting part 133 is the second axis, and the first axis coincides with the second axis.

[0087] In this way, when the sliding part 132 rotates synchronously with the rotating part 131, on the one hand, the clamping head 135 can be kept rotating synchronously, which is convenient for adjusting the clamping angle of the clamping head 135. On the other hand, the sliding drive part 134 is fixed to the base 12 through the first bracket 18, and the connecting part 133 is connected between the sliding part 132 and the sliding drive part 134. The sliding part 132 can rotate relative to the connecting part 133, and the sliding drive part 134 is fixed to the base, which can ensure that the sliding drive part 134 will not rotate synchronously; and the sliding drive part 134 can also drive the sliding part 132 to slide in the slide groove in the base 12 through the connecting part 133 to realize the opening and closing of the clamping head 135.

[0088] It should be noted that the sliding portion 132 can rotate synchronously with the rotating portion 131 because there is a matching and limiting relationship between the interior of the rotating portion 131 and the sliding portion 132. The specific structural form can be set according to actual needs. The sliding portion 132 cannot rotate relative to the rotating portion 131, but can slide up and down relative to the rotating portion 131, thereby facilitating the sleeve to open or close the chuck.

[0089] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the clamping device 1 further includes a first bearing 15 .

[0090] The first bearing 15 is disposed between the rotating portion 131 and the base 12 , and the rotating portion 131 and the base 12 are rotatably connected via the first bearing 15 .

[0091] Specifically, the rotation resistance of the rotating part 131 can be reduced by providing the first bearing 15 .

[0092] In some embodiments of the present application, the connecting portion 133 includes a connecting rod 1331 and a second bearing 1332 .

[0093] One end of the connecting rod 1331 is fixedly connected to the sliding driving part 134;

[0094] The second bearing 1332 is fixedly disposed at the other end of the connecting rod 1331 , and the second bearing 1332 is located in the sliding portion 132 , and the sliding portion 132 and the connecting rod 1331 are rotatably connected via the second bearing 1332 .

[0095] Specifically, the sliding driving part 134 directly drives the connecting rod 1331 to move. The movement of the connecting rod 1331 can drive the sliding part 132 to slide in the sliding groove of the rotating part 131, and the connecting rod 1331 plays the role of a bridge in the middle.

[0096] Specifically, by providing the second bearing 1332 at the other end of the connecting rod 1331 , the sliding part 132 can be rotated relative to the sliding driving part 134 , so that the rotation of the sliding part 132 does not conflict with the sliding of the sliding part 132 .

[0097] In certain embodiments of the present application, the sliding drive unit 134 includes a cylinder 1341 , and the connecting rod 1331 is fixedly connected to a piston rod of the cylinder 1341 , and the piston rod of the cylinder 1341 drives the connecting rod 1331 to extend and retract.

[0098] Exemplarily, the connecting rod 1331 is fixed to the piston rod by threaded connection or welding.

[0099] In some embodiments of the present application, the sliding portion 132 includes a sliding plate 1321 , a mounting cylinder 1322 and a guide column 1323 .

[0100] The sliding plate 1321 is located in the sliding groove of the rotating part 131 and is slidably connected to the rotating part 131;

[0101] The mounting cylinder 1322 is a cylindrical structure with an opening at the upper end. The mounting cylinder 1322 is located in the rotating portion 131 and is fixedly arranged at the upper end of the sliding plate 1321. The second bearing 1332 is arranged in the mounting cylinder 1322. One end of the connecting rod 1331 is connected to the piston rod, and the other end of the connecting rod 1331 passes through the opening on the mounting cylinder 1322 and enters the mounting cylinder 1322 to be connected to the second bearing.

[0102] The upper end of the guide column 1323 is fixedly connected to the sliding plate 1321, and the lower end of the guide column 1323 passes through the guide hole at the bottom of the rotating part 131 and is fixedly connected to the sleeve 136. The guide hole plays a guiding role on the one hand, and can also limit the rotation of the sliding part 132 relative to the rotating part 131 on the other hand.

[0103] In some embodiments of the present application, the sliding portion 132 further includes a buffer block 1324 .

[0104] The buffer block 1324 is disposed in the mounting tube 1322 and is located between the connecting rod 1331 and the sliding plate 1321 .

[0105] Specifically, the buffer block 1324 is made of rubber material.

[0106] In some embodiments of the present application, the clamping device 1 further includes a sensor 16 and a sensor sheet 17 .

[0107] The sensor 16 is disposed on one of the base 12 and the rotating portion 131;

[0108] The sensing sheet 17 is disposed on the other of the base 12 and the rotating portion 131 , and the position of the sensing sheet 17 corresponds to the position of the sensor 16 ;

[0109] The sensor 16 and the sensor sheet 17 are configured to locate the initial position of the rotating portion 131 .

[0110] Specifically, in the initial position, the sensing sheet 17 extends into the sensor 16, and the rotation angle is 0; when the rotating part 131 starts to rotate, the sensing sheet 17 rotates out of the sensor 16, and the sensor 16 cannot sense the sensing sheet 17. At this time, it means that the rotating part 131 is rotating. By setting the sensor 16 and the sensing sheet 17, the initial positions of the rotation can be ensured to be consistent, which facilitates the control of the rotation angle of the rotating part 131.

[0111] In the second aspect, an embodiment of the present disclosure provides a device for coupling optical devices, wherein the device for coupling optical devices includes a Z-axis motion mechanism 2 and a clamping device 1, wherein the clamping device 1 includes a mounting portion 11, a base 12, a rotating clamping assembly 13 and a rotating driving portion 14.

[0116] The chuck 135 is arranged at the bottom of the rotating part 131, and is used to clamp or release the optical device 3; the sleeve 136 is arranged at the bottom of the sliding part 132, and is sleeved on the outside of the chuck 135; the sliding part 132 is configured to be slidably connected with the rotating part 131, and rotate synchronously with the rotating part 131; one end of the connecting part 133 is rotatably connected with the sliding part 132, and the other end of the connecting part 133 is fixedly connected with the sliding driving part 134, and the sliding driving part 134 drives the sliding part 132 to reciprocate relative to the rotating part 131 through the connecting part 133, so as to drive the sleeve 136 to open or close the chuck 135;

[0117] The rotation driving portion 14 drives the rotating portion 131 to rotate so as to drive the clamping head 135 to rotate, thereby changing the clamping angle of the clamping head 135 .
