TECHNICAL FIELD

[0001] The present application relates to the technical field of optical module coupling, in particular to a double Lens coupling device for optical module products and a coupling method thereof. BACKGROUND

[0002] The coupling of an optical module and a Lens is a key process in the packaging of an optical module, which refers to a process of realizing low-loss transmission of optical signals between a laser light source in an optical module and an optical fiber through high-precision spatial alignment and fixation with a Lens as an intermediate optical element.

[0003] In the current production process, the coupling of the Lens can only realize automatic coupling and automatic dispensing and curing, and the feeding, power supply and plugging of the optical module all need to be performed manually. The products with two Lenses need to be repeatedly coupled, the whole process has a high degree of human involvement, the degree of automation is not high, and the skills of the operators are required to be high. Moreover, the optical module product has directionality, and the optical module product needs to be ensured to be in a forward direction during coupling. However, the directions of the optical module products in the Tray are forward or reverse, which increases the difficulty of material taking and affects the coupling efficiency. SUMMARY

[0004] The present application aims to overcome the deficiencies in the prior art and provide a double Lens coupling device for optical module products and a coupling method thereof. Two coupling modules are used to simultaneously couple two Lenses on the optical module product, and the rotation of the optical module gripper around the Z axis is used to correct the direction of the optical module product in the Tray, thereby significantly improving the overall coupling efficiency.

[0022] Among them, the coupling carrier 101 is used to hold the optical module product, the leveling assembly 102 drives the coupling carrier 101 to rotate around the X and / or Y axis to realize the adjustment of the horizontal posture of the optical module product, and ensure that the optical module product is in a horizontal position before coupling, the rotating shaft 103 drives the leveling assembly 102 and the coupling carrier 101 to rotate as a whole around the Z axis to realize the adjustment of the angle of the optical module product in the horizontal plane to adapt to the simultaneous coupling of the two lenses; the lens carrier 104 is used to hold and place the lens, the double lower visual module 108 is used to position the lens clamped by the coupling module 3, and the power supply mechanism 106 is used to realize automatic power supply for the optical module product on the coupling carrier 101.

[0023] The above-mentioned coupling carrier 101 comprises a support 111 connected with the output end of the leveling assembly 102, a plurality of support blocks 112 for supporting the optical module product are fixedly installed on the top of the support 111, and a clamping carrier for clamping the optical module product is arranged on the periphery of the support block 112.

[0024] The clamping carrier includes a first clamping jaw 113 and a second clamping jaw 114 arranged inside the support 111, the top of the support 111 is provided with two first avoiding holes in the width direction of the optical module product, and is provided with second avoiding holes on both sides in the length direction of the optical module product, the upper part of the first clamping jaw 113 extends to the outside of the support 111 through the first avoiding hole, and the second clamping jaw 114 extends to the outside of the support 111 through the second avoiding hole, that is, the first clamping jaw 113 is used for clamping the front and back (width direction) of the optical module product, and the second clamping jaw 114 is used for clamping the left and right (length direction) of the optical module product, so that the optical module product can be centered under the support of the supporting block 112, facilitating positioning and subsequent coupling work.

[0025] The power supply mechanism 106 includes a lifting component 162, a translation component 163, a mounting seat 164 and a probe plate 165, the lifting component 162 and the translation component 163 can adopt existing air cylinders or electric cylinders, the lifting component 162 is fixedly installed on one side of the support 111 through the connecting plate 161, the translation component 163 is installed on the output end of the lifting component 162, the lifting component 162 is parallel to the Z-axis direction, the translation component 163 is parallel to the length direction of the optical module product, and the probe plate 165 is installed on the mounting seat 164, the mounting seat 164 is installed on the output end of the translation component 163, that is, the probe plate 165 is connected with the support 111, and the probe on the probe plate 165 is connected with the port of the optical module product, so that automatic power supply of the optical module product can be realized, and the dependence on manual operation and the skill requirement of the operator are reduced.

[0026] Specifically, the rotating shaft 103 and the leveling assembly 102 are prior art, which will not be described in detail here, and the first clamping jaw 113 and the second clamping jaw 114 can adopt electric clamping jaws. After the carrying module 4 places the optical module product on the supporting block 112, the first clamping jaw 113 and the second clamping jaw 114 clamp and position the optical module product from two directions respectively, so that the optical module product can be centered relative to the top of the support 111, facilitating subsequent power supply and plug-in; after the optical module is clamped by the clamping carrier, the translation component 163 drives the probe plate 165 to move to the upper side of the port of the optical module product, and then the lifting component 162 drives the probe plate 165 to move downward, so that the probe on the probe plate 165 is plugged into the port on the optical module product, thereby realizing power supply of the optical module product and facilitating subsequent coupling work; after the power supply is completed, the two coupling modules 3 clamp the Lens on the lens carrier 104, position the Lens through the downward vision module 108, and then perform double-Lens coupling with the optical module product.

[0027] In order to improve the separation effect of the probe plate 165 and the optical module product, a protrusion is arranged on the side of the top end of the first clamping jaw 113 close to the optical module product, so as to prevent the optical module product from separating from the support 111 together with the probe plate 165.

[0028] As Figure 10 and Figure 11 shown, the silo flow line module 2 includes a material taking flow line 201, a positioning flow line 202 and a material collecting flow line 203 connected in sequence along the X axis, the material taking flow line 201 is provided with a material feeding silo 204 away from one side of the positioning flow line 202, and the material collecting flow line 203 is provided with a material collecting silo 205 away from one side of the positioning flow line 202, the Tray tray 209 stacked in the material feeding silo 204 is placed with optical module products to be coupled, and the Tray tray 209 stacked in the material collecting silo is placed with coupled optical module products, that is, the material feeding silo 204 is used to provide the Tray tray 209 loaded with optical module products to be coupled, and the material collecting silo 205 is used to store the Tray tray 209 loaded with optical module products after coupling.

[0029] Among them, the above flow lines all adopt belt conveying, and the material taking flow line 201 and the material collecting flow line 203 are both provided with a hook rod movable along the X axis direction, the hook rod on the material taking flow line 201 can obtain the Tray tray 209 fully loaded with optical module products to be coupled from the material feeding silo 204, and the hook rod on the material collecting flow line 203 can push the Tray tray 209 fully loaded with optical module products after coupling to the material collecting silo 205, that is, the material feeding silo 204 moves downward layer by layer, and the material collecting silo 205 moves upward layer by layer to cooperate with the hook rod to realize the obtaining or storing of the Tray tray 209, and the obtaining and storing of the Tray tray 209 are all prior art, which will not be described in detail here.

[0030] Further, the positioning flow line 202 is provided with a blocking module 206 close to one end of the material collecting flow line 203, a limiting frame 207 is fixedly installed at the top of the positioning flow line 202, and a jacking module 208 is arranged in the positioning flow line 202, and after the Tray tray 209 entering the positioning flow line 202 contacts the blocking module 206, the jacking module 208 can jack up the Tray tray 209 to be attached to the limiting frame 207, so as to complete the jacking and positioning of the Tray tray 209, and facilitate the module 4 to be carried later to take or place the optical module products.

[0031] Among them, the blocking module 206 includes a first telescopic assembly obliquely arranged at the end of the positioning flow line 202, and a baffle is installed at the output end of the first telescopic assembly, the jacking module 208 includes a second telescopic assembly fixedly installed in the inner side of the positioning flow line 202, and a top plate is installed at the output end of the second telescopic assembly, the first telescopic assembly and the second telescopic assembly can both adopt a pneumatic cylinder, an electric cylinder or an oil cylinder, and a material taking hole is formed in the inside of the limiting frame 207.

[0032] Specifically, the tray 209 obtained from the feeding bin 204 is transported to the positioning flow line 202 by the taking flow line 201, and then the positioning flow line 202 continues to transport the tray 209 until the baffle of the blocking module 206 is extended to contact the tray 209 to stop the tray 209. Then the top plate of the lifting module 208 contacts the bottom surface of the tray 209 to lift the tray 209 away from the positioning flow line 202, until the top surface of the tray 209 contacts the bottom surface of the limiting frame 207. At this time, the optical module products on the tray 209 are all located in the taking hole, and the handling module 4 can take or place the optical module products from the taking hole.

[0033] The first telescopic assembly and the baffle of the blocking module 206 are obliquely arranged, which can improve the stopping effect of the tray 209 and make the force on the tray 209 more reasonable. After the tray 209 is lifted, it is attached to the limiting frame 207, which can not only position the lifting height of the tray 209, but also ensure that the lifting height of each tray 209 is consistent, thereby improving the precision of the optical module gripper 407 in grabbing the optical module products.

[0034] When the optical module products in the taking hole are all coupled, the top plate of the lifting module 208 is reset, the tray 209 falls back to the positioning flow line 202, and the baffle of the blocking module 206 is retracted, so that the tray 209 full of coupled optical module products can smoothly flow to the receiving flow line 203, and then be stored in the receiving bin 205 through the receiving flow line 203. That is, the tray 209 transported on the taking flow line 201 is full of optical module products to be coupled, the tray 209 transported on the receiving flow line 203 is full of coupled optical module products, and the tray 209 from the taking flow line 201 can be stopped and lifted at the positioning flow line 202, so that the handling module 4 can take or place the optical module products therefrom. Through the bin flow line module 2, the degree of human participation can be reduced, and the degree of automation of the equipment can be improved.

[0035] As shown in Figure 3 , Figure 8 and Figure 9 , the coupling module 3 is provided with two, which are oppositely distributed on the left and right sides of the jig module 1. The two coupling modules 3 are completely the same in structure, including the Lens gripper 301, the suction nozzle 302, the UV lamp assembly 303, the translational assembly 304 and the rotating assembly 305. The translational assembly 304 is installed on the platform 5, the rotating assembly 305 is installed on the output end of the translational assembly 304, and the Lens gripper 301, the suction nozzle 302 and the UV lamp assembly 303 are all installed on the output end of the rotating assembly 305, that is, the three can realize synchronous motion relative to the platform 5.

[0036] Wherein, the Lens clamp jaw 301 and the suction nozzle 302 jointly realize the clamping of the Lens, and the suction nozzle 302 is located at the inner side of the Lens clamp jaw 301, and each coupling module 3 is provided with two groups of UV lamp assemblies 303, which are symmetrically distributed on both sides of the Lens clamp jaw 301; the rotating assembly 305 is used to drive the Lens clamp jaw 301, the suction nozzle 302 and the UV lamp to rotate synchronously around the X, Y and Z axes, and the translating assembly 304 is used to drive the Lens clamp jaw 301, the suction nozzle 302 and the UV lamp to translate synchronously along the X, Y and Z axes, and the rotating assembly 305 and the translating assembly 304 are both prior art, which will not be described in detail here, that is, the Lens clamped by the coupling module 3 has six degrees of freedom, which facilitates the coupling of the Lens with the optical module product on the jig module 1, and the UV lamp assembly 303 plays a curing role.

[0037] After the handling module 4 of the coupling equipment handles the optical module product from the Tray disc 209 on the stock bin flow line module 2 to the coupling carrier 101 of the jig module 1, the coupling modules 3 on both sides of the jig module 1 can simultaneously complete the coupling of two Lens on the optical module product, and after the coupling is completed, the optical module product is transported back to the Tray disc 209 on the stock bin flow line module 2 through the handling module 4, so that repeated coupling actions are avoided, time is saved, and coupling efficiency is improved.

[0038] As shown in Figure 1 , Figure 6 and Figure 7 , the handling module 4 includes a mounting plate 406 that can move along the X, Y and Z axes, and the mounting plate 406 is provided with an optical module clamp jaw 407, an upper visual module 408 and a dispensing assembly 409, all of which can move synchronously with the mounting plate 406, the upper visual module 408 is located between the dispensing assembly 409 and the optical module clamp jaw 407, and the optical module clamp jaw 407 can rotate around the Z axis.

[0039] Wherein, the optical module clamp jaw 407 is an electric clamp jaw, which can clamp the optical module product, the upper visual module 408, the lower visual module 108 and the dispensing assembly 409 all adopt prior art, the dispensing assembly 409 is used for dispensing operation during coupling, the upper visual module 408 is used for positioning the Lens and the optical module product, and the lower visual module 108 is used for positioning the Lens clamped by the Lens clamp jaw 301 and the suction nozzle 302.

[0040] The upper visual module 408, the dispensing assembly 409 and the optical module clamp jaw 407 are all arranged on the mounting plate 406 of the handling module 4, and the UV lamp assemblies 303 are arranged on both sides of the Lens clamp jaw 301 of the coupling module 3, which optimizes the overall space layout, ensures that the coupling of the two Lens can be performed simultaneously, and avoids mutual interference of the two coupling modules 3 during coupling.

[0041] Further, two gantry frames 401 are fixedly installed on the platform 5, the bin flow line module 2 passes through the two gantry frames 401, the two gantry frames 401 are oppositely arranged above the platform 5, and the top of the two gantry frames 401 is connected through a cross beam 402 which is parallel to the X-axis direction. One of the two gantry frames 401 is provided with a Y-axis linear module 403, and the other gantry frame 401 is provided with a guide rail parallel to the Y-axis. One end of the cross beam 402 is connected with the output end of the Y-axis linear module 403, and the other end is connected with the guide rail in a sliding manner, so that the cross beam 402 can move along the Y-axis direction.

[0042] The cross beam 402 is provided with an X-axis linear module 404, the output end of the X-axis linear module 404 is provided with a Z-axis linear module 405, and a mounting plate 406 is mounted on the output end of the Z-axis linear module 405. That is, under the joint driving of the X-axis linear module 404, the Y-axis linear module 403 and the Z-axis linear module 405 (all of which are prior art), the mounting plate 406 can move in the space along the X, Y and Z axes, so as to realize the carrying of the optical module product between the positioning flow line 202 of the bin flow line module 2 and the coupling carrier 101 of the jig module 1 by the optical module clamp jaw 407.

[0043] Specifically, the mounting plate 406 is provided with a driving motor, the output shaft of the driving motor is parallel to the Z-axis direction, and the optical module clamp jaw 407 is mounted on the output shaft of the driving motor. Under the driving of the driving motor, the optical module clamp jaw 407 can rotate 360 degrees around the Z-axis. Through the rotation design of the optical module clamp jaw 407, even if the feeding direction of the optical module product on the Tray disc 209 is reversed, it can be adjusted and corrected in time, reducing the difficulty of taking the material, improving the quality stability of the product, and improving the yield and productivity.

[0044] The optical module products in the Tray disc 209 are placed in different directions, some are in the forward direction and some are in the reverse direction. When coupling, the port of the optical module product needs to be close to the power supply mechanism 106, that is, it needs to be in the forward position to realize power supply, so as to perform subsequent coupling operation. Therefore, before grabbing the optical module product from the Tray disc 209, the upper visual module 408 can be used to take a photo to judge the forward and reverse of the optical module product. If it is in the forward direction, the optical module clamp jaw 407 can be used to grab and directly carry it to the coupling carrier 101. If it is in the reverse direction, for the product with different positions on both sides in the width direction, the optical module clamp jaw 407 is first rotated 180 degrees around the Z-axis before grabbing, and then the optical module clamp jaw 407 is grabbed, and then rotated 180 degrees after grabbing, so that the optical module product is converted from the reverse position to the forward position. For the product with the same position on both sides in the width direction, the optical module clamp jaw 407 can be used to grab the optical module product, and then rotated 180 degrees to adjust the position of the optical module product.

[0045] In addition, the lens carrier 104 is provided with a glue wiping mechanism 105 on the side opposite to the coupling carrier 101, and the glue dispensing assembly 409 needs to be wiped after being used for a period of time to ensure the accuracy of the glue output. The glue wiping mechanism 105 includes a clamping jaw assembly mounted on a support plate 107, the clamping jaw assembly has two clamping plates capable of being opened and closed, the inner sides of the two clamping plates are fixedly installed with glue wiping pads, and one side of the clamping jaw assembly is further provided with a glue testing block, the glue testing block is fixedly installed on the top of the support plate 107, is made of stainless steel material, and has a flat top surface.

[0046] When the glue dispensing assembly 409 runs for a period of time, the carrying module 4 moves it to the glue wiping mechanism 105, so that the glue dispensing head of the glue dispensing assembly 409 extends between the two clamping plates, the clamping plates are close to each other, and the excess glue on the glue dispensing head is wiped off through the glue wiping pads; then the glue dispensing assembly 409 performs glue dispensing test on the glue testing block, and the glue output is photographed through the upper visual module 408 to know whether the glue output is normal, so as to ensure the stable operation of the glue dispensing operation in the coupling process and improve the quality of the product.

[0047] In the embodiment two, on the basis of the embodiment one, the application further provides a double Lens coupling method for an optical module product, which adopts the double Lens coupling device for the optical module product.

[0048] As shown in Figure 13 A double Lens coupling method for an optical module product, including the following steps: acquisition and positioning of the Tray 209, transfer, clamping and power supply of the optical module product to be coupled, Lens taking and coupling of the coupling module 3, double Lens coupling process of the optical module product, and transfer of the optical module product after coupling. Through the method, the modules of the coupling device can be coordinated and matched, the division of labor between the modules is clear and related, the transfer and coupling logic of the optical module product is rigorous and orderly, and the stable operation of the coupling device is ensured.

[0049] S1, acquisition and positioning of the Tray 209: the taking flow line 201 acquires the Tray 209 loaded with the optical module product to be coupled from the feeding bin 204 and delivers it to the positioning flow line 202, and after being stopped by the blocking module 206, the Tray 209 is lifted to the limiting frame 207 by the lifting module 208 to complete the lifting positioning.

[0050] After the tray 209 is transported to the positioning flow line 202 from the taking flow line 201, the positioning flow line 202 continues to transport the tray 209 to the limiting frame 207, the baffle of the blocking module 206 is extended to contact the tray 209 to stop the tray 209, then the top plate of the lifting module 208 is in contact with the bottom surface of the tray 209 to lift the tray 209 away from the positioning flow line 202, until the top surface of the tray 209 is in contact with the bottom surface of the limiting frame 207, at this time, the optical module products on the tray 209 are all located in the taking hole, and the handling module 4 can take or place the optical module products on the tray 209 from the taking hole.

[0051] S2, transfer, clamping and power supply of the optical module product to be coupled: the optical module gripper 407 grabs the optical module product to be coupled, and then handles the optical module product to the coupling carrier 101, clamps the optical module product through the clamping carrier, and then the power supply mechanism 106 supplies power to the optical module product through the probe plate 165.

[0052] The optical module gripper 407 of the handling module 4 moves to the feeding position of the optical module product, and before grabbing the optical module product to be coupled, the placement direction of the optical module product in the tray 209 is acquired through the upper vision module 408, if the optical module product is forward, the optical module product is directly grabbed and handled to the coupling carrier 101; if the optical module product is reverse and there is a difference in the positioning of the two sides in the width direction, the optical module gripper 407 is rotated by 180 degrees around the Z axis before grabbing, and then the optical module gripper 407 is grabbed, and after grabbing, the optical module gripper 407 is rotated by 180 degrees again, so that the optical module product is converted from the reverse position to the forward position; if the optical module product is reverse and there is no difference in the positioning of the two sides in the width direction, the optical module product can also be directly rotated by 180 degrees after the optical module gripper 407 grabs the optical module product to correct the position of the optical module product.

[0053] When the optical module product is handled to the supporting block 112 of the coupling carrier 101, the first gripper 113 and the second gripper 114 clamp and position the optical module product from two directions, so that the optical module product is centered relative to the top of the support 111 to complete clamping, then the translation component 163 drives the probe plate 165 to move to the upper side of the port of the optical module product, and the lifting component 162 drives the probe plate 165 to move downward, so that the probe on the probe plate 165 is inserted into the port on the optical module product to realize power supply to the optical module product.

[0054] S3, taking and coupling of the Lens by the coupling module 3: the laser position of the optical module product and the Lens taking position are positioned by the upper vision module 408, and the two coupling modules 3 clamp the Lens to make the Lens couple with the optical module product in a double-Lens mode.

[0055] In the process of clamping and power supply of the optical module product on the coupling carrier 101, the carrying module 4 drives the upper visual module 408 to move above the lens carrier 104 to position the lens taking position of the Lens, and then the two coupling modules 3 clamp the Lens of the lens carrier 104 through the Lens clamp jaw 301 and the suction nozzle 302 at the same time. At this time, the upper visual module 408 moves above the optical module product to position the laser position of the optical module product, and then the two coupling modules 3 clamp the Lens and the optical module product to perform double Lens coupling.

[0056] If the laser position of the optical module product and the Lens taking position are acquired in sequence, the corresponding positioning needs to be acquired by the upper visual module 408 after the optical module product is clamped and powered on the coupling carrier 101. Compared with this, the method positions the Lens taking position in the process of clamping and power supply of the optical module product, and then acquires the laser position of the optical module product in the process of clamping the Lens by the coupling module 3, so as to ensure that the two can be coupled smoothly subsequently, and the coupling efficiency is improved by cooperation.

[0057] S4, double Lens coupling process of the optical module product: in the coupling process, the two lenses and the optical module product are first coupled coarsely, then the glue dispensing assembly 409 is used to complete glue dispensing, and then fine coupling is performed, and then UV lamp assembly 303 is used to realize curing.

[0058] After the coupling module 3 clamps the Lens, a preliminary pre-coupling is first performed with the optical module product, and whether the optical module product can work normally is tested. When it can work normally, glue dispensing is performed through the glue dispensing assembly 409, the Lens is coupled with the optical module product again by the coupling module 3 after glue dispensing is completed, until the coupling is in place, and then UV curing is realized through the UV lamp assembly 303 to irradiate the coupling position, and the coupling is completed. In order to improve the production efficiency, the coupling device adopts two six-axis coupling modules 3, and two groups of UV lamps are configured for curing.

[0059] S5, transfer of the optical module product after coupling: after the coupling is completed, the probe plate 165 of the power supply mechanism 106 is disconnected from the optical module product and moves back to the original position, the clamping carrier releases the optical module product, and the optical module clamp jaw 407 grabs the coupled optical module product and carries it back to the Tray disc 209 which is lifted.

[0060] When the power supply mechanism 106 is reset, the lifting component 162 first drives the probe plate 165 to move upward, so that the probe plate 165 is separated from the optical module product, and then the translation component 163 drives the probe plate 165 to move to a safe position outside the optical module product, thereby avoiding affecting the clamping work of the subsequent optical module clamping jaw 407. When the power supply mechanism 106 is reset, the first clamping jaw 113 and the second clamping jaw 114 release the optical module product, and then the optical module clamping jaw 407 clamps and carries the optical module product back to the Tray 209 above the positioning flow line 202.

[0061] Further, steps S2-S5 are repeated until the optical module products in the Tray 209 are all coupled, and then the lifting module 208 and the blocking module 206 are reset, the Tray 209 falls back to the positioning flow line 202 and is transported to the storage bin 205 through the storage flow line 203. When the optical module products in the material taking hole are all coupled, the top plate of the lifting module 208 is reset, the Tray 209 falls back to the positioning flow line 202, the blocking plate of the blocking module 206 is retracted, so that the Tray 209 full of coupled optical module products can smoothly flow to the storage flow line 203, and then the Tray 209 is stored in the storage bin 205 through the storage flow line 203, thereby completing the coupling of the optical module products on the Tray 209, and then repeating step S1 to couple the optical module products on the next Tray 209.

[0062] When the optical module products in the material taking bin 204 are all coupled, the Tray 209 full of coupled optical module products is manually collected from the storage bin 205, and the Tray 209 full of optical module products to be coupled is refilled into the material taking bin 204, and the next round of coupling operation is started.

[0063] In summary, the application provides a double Lens coupling device for optical module products and a coupling method thereof, which realizes automatic feeding and discharging of optical module products, automatic power supply and simultaneous coupling of two lenses. The optical module products are placed in the Tray disc 209, the multi-layer Tray disc 209 is concentrated into the feeding bin 204 and the discharging bin 205, the Tray disc 209 is taken from the feeding bin 204 through the material taking flow line 201 and is placed into the discharging bin 205 through the discharging flow line 203, the Tray disc 209 is stopped by the positioning flow line 202, and the optical module products are taken from or placed in the Tray disc 209 by the carrying module 4; through the floating plug design of the power supply mechanism 106, when the carrying module 4 completes the automatic feeding of the optical module products, the power supply probe plate 165 is used to complete the power supply action of the optical module products; the Lens is taken from the lens carrier 104 through the double six-axis coupling module 3, and the Lens coupling action is simultaneously performed, so that the Lens coupling time of a single optical module is greatly shortened, and the production capacity is improved. The optical module clamping jaw 407 of the carrying module 4 has a 360° rotation function, so that even if the feeding direction in the Tray disc 209 is reversed, there is no need to worry.
