DETAILED DESCRIPTION

[0016] The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. Embodiment 1

[0017] like Figure 1 As shown, a device for synchronously coupling an array lens and FA includes a carrier mechanism 1, a transport and glue dispensing mechanism 2 and a loading mechanism 3. The transport and glue dispensing mechanism 2 is located at the rear side of the carrier mechanism 1, and is mainly used for transporting an optical module substrate 4 and implementing glue dispensing; two loading mechanisms 3 are provided, which are relatively distributed on the left and right sides of the carrier mechanism 1, and the loading mechanism 3 located on the left is used for transporting the lens, and the loading mechanism 3 located on the right is used for transporting the FA, so as to ensure that the array lens and the FA can be moved to the coupling position of the optical module substrate 4.

[0018] The transporting and dispensing mechanism 2 is used for transporting the optical module substrate 4 and dispensing glue, and the loading mechanisms 3 on both sides are used for moving the array lens and FA respectively, thereby simplifying the existing multi-channel lens coupling and mounting production process that needs to be repeated many times to only one coupling and mounting, that is, the FA is also coupled synchronously during the coupling process of the lens, and the two processes are combined into one process, which simplifies the production process and greatly improves the production efficiency of the optical module.

[0019] FA is the abbreviation of Fiber Array, which means an optical fiber array, which uses a substrate with a V-groove to install a bundle of optical fibers or an optical fiber ribbon on the substrate at specified intervals to form an array.

[0020] like Figure 8 As shown, lasers 402 corresponding to the number and positions of the optical channels are arranged on the optical module substrate 4, and a Pad point 401 electrically connected to the laser 402 is arranged on one side of the laser 402.

[0021] As mentioned above, the optical module substrate 4 is a PCB board, and the Pad point 401 is a metallized area on the PCB board for soldering electronic component pins or connecting wires, which is usually a copper foil area in a circular, rectangular or other shape. It provides electrical connection for electronic components (here, the laser 402). During the soldering process, the solder connects the component pins with the Pad point 401 to achieve circuit conduction, ensuring that the current can be smoothly transmitted between the various components, so that the entire circuit can work normally.

[0022] like Figure 1 and Figure 2 As shown, the carrier mechanism 1 includes a coupling carrier 101 capable of adjusting its own angle, a substrate fixture 102 is provided on one side of the coupling carrier 101 close to the transport and dispensing mechanism 2, and a lens fixture 103 is provided on the other side; the substrate fixture 102 is used to load the optical module substrate 4, and the lens fixture 103 is used to load the array lens, both of which can be detachably installed on the feeding carrier for easy replacement; the two feeding carriers are relatively distributed on both sides of the coupling carrier 101.

[0023] Among them, the substrate jig 102 is provided with a plurality of storage slots for placing the optical module substrate 4, and the lens jig 103 is provided with a plurality of grooves for placing the lenses, and the plurality of grooves are distributed in a rectangular array on the lens jig 103; according to the process requirements, a plurality of lens jigs 103 can be provided, and the substrate jig 102 and the optical module substrate 4 can be fixedly mounted on the corresponding feed carrier by screws.

[0024] A rotation drive assembly 104 is provided below the coupling platform 101, and the coupling platform 101 is installed at the output end of the rotation drive assembly 104, that is, under the drive of the rotation drive assembly 104, the coupling platform 101 can adjust its own angle in space to ensure that it is in the best plane position during coupling.

[0025] As mentioned above, a first visual component 106 is provided on one side of the coupling platform 101 close to the lens fixture 103. The first visual component 106 adopts the existing technology and is used for position calibration of the array lens and FA and alignment of the array lens, FA and the laser 402; the first visual component 106 is horizontally arranged and parallel to the X-axis direction.

[0026] Specifically, the coupling platform 101 is guided by the overhead visual camera and rotates around the Z axis by the rotation drive component 104 to ensure that the light emission direction of the laser 402 remains consistent after each material is placed on the coupling platform 101, and is along the X-axis direction; the rotation drive component 104 here can adopt the existing automatic rotation axis around the Z axis.

[0027] Furthermore, a power supply probe mechanism 105 is provided on the left side of the coupling stage 101 . The power supply probe mechanism 105 is used to supply power to the laser 402 , and the power supply probe mechanism 105 can be positionally adjusted around the X, Y, and Z axes.

[0028] Specifically, the power supply probe mechanism 105 includes a probe card that can contact the pad point 401. A driving module is provided at the bottom of the probe card, and the probe card is installed at the output end of the driving module. Under the guidance of the overhead visual camera, the driving module drives the probe card needle to move above the pad point 401, and then the power supply probe mechanism 105 descends to a fixed height along the Z axis, so that the probe is inserted into the pad point 401, thereby powering the laser 402.

[0029] The power supply probe mechanism 105 uses an automatic adjustment axis to control the power supply of the probe card. Since there are many needles on the probe card, the position of the probe card needs to be calibrated. Here, the existing visual technology is combined with the three-dimensional drive module to automatically calibrate the contact position between the probe and the Pad point 401. All the pins of the probe card are connected to the circuit through the conversion control board, and the horizontality of the probe card is adjusted by conduction to avoid the instability of manual calibration and improve efficiency.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the handling and dispensing mechanism 2 includes a first Y-axis linear module 201, a first vertical plate 202 is installed at the output end of the first Y-axis linear module 201, a first Z-axis linear module 203 is arranged on the first vertical plate 202, a first X-axis linear module 204 is installed at the output end of the first Z-axis linear module 203, the output end of the first X-axis linear module 204 is connected to a support block 205, and a stage clamp 207 is installed on the support block 205, and the stage clamp 207 is used to grab the optical module substrate 4.

[0031] The first Y-axis linear module 201, the first Z-axis linear module 203 and the first X-axis linear module 204 all adopt existing linear modules, such as electric cylinders or linear motors, etc., whose output ends can output linear motion in corresponding directions, thereby driving the support block 205 and the carrier clamp 207 to move along the X, Y and Z axis directions in space.

[0032] The carrier clamp 207 is installed on the support block 205 through a telescopic component. The telescopic component is parallel to the Z-axis direction and can adopt an electric cylinder, a pneumatic cylinder, etc. The carrier clamp 207 is connected to the output end of the telescopic component and can move relative to the support block 205 along the Z-axis direction, so as to better realize the grasping and placement of the optical module substrate 4.

[0033] As mentioned above, a glue dispensing component 5 is also provided on one side of the carrier clamp 207. The glue dispensing component 5 adopts the existing glue dispensing technology to glue and fix the lens and FA at the coupling position on the optical module substrate 4; and in order to ensure the position accuracy of the glue dispensing and observe whether the position of the lens and FA relative to the optical module substrate 4 changes before and after the glue dispensing, a second visual component 206 is provided on one side of the carrier clamp 207. The second visual component 206 is longitudinally arranged and parallel to the Z-axis direction.

[0034] Among them, the second visual component 206 and the glue dispensing component 5 are both existing technologies, and the second visual component 206 is fixedly connected to the support block 205 through a cross beam, the glue dispensing component 5 is connected to the cross beam, and the glue dispensing head of the glue dispensing component 5 is located below the cross beam, on one side of the carrier clamp 207.

[0035] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the loading mechanism 3 includes a second X-axis linear module 301, a second Y-axis linear module 302 is installed at the output end of the second X-axis linear module 301, a second vertical plate 303 is installed at the output end of the second Y-axis linear module 302, a second Z-axis linear module 304 is installed on the second vertical plate 303, the output end of the second Z-axis linear module 304 is connected to a rotating mechanism 305 capable of rotating around the X, Y, and Z axis directions, and the output end of the rotating mechanism 305 is installed with a clamp assembly 6 for grabbing a lens or fixing FA.

[0036] The output ends of the second X-axis linear module 301, the second Y-axis linear module 302 and the second Z-axis linear module 304 can respectively output linear motion in corresponding directions, thereby driving the rotating mechanism 305 and the clamp assembly 6 to move along the X, Y and Z axes in space; and the rotating mechanism 305 can rotate around the X, Y and Z axes, so the clamp assembly 6 can move in the X, Y and Z axes while rotating around three axes, that is, it has six degrees of freedom in space, which is convenient for adjusting the position of the lens and FA to ensure that the coupling between the two can reach the optimal position.

[0037] Among them, the second X-axis linear module 301, the second Y-axis linear module 302, the second Z-axis linear module 304 and the rotating mechanism 305 are all existing technologies. The rotating mechanism 305 is a high-precision automatic rotating axis, which adopts the existing three-dimensional automatic angle axis rotating around the X, Y and Z axes. Its structure is not described in detail here.

[0038] As described above, UV lamps 306 are provided on both sides of the fixture assembly 6, and the UV lamps 306 on both sides are symmetrically distributed in an inverted V shape. The UV lamp 306, that is, the ultraviolet lamp, is a kind of lamp that can emit ultraviolet rays and has a light curing function. It is used to cure encapsulation glue, photoresist, etc. of electronic components. Here, it is used to cure the glue dispensed by the dispensing assembly 5 for the lens and FA coupling.

[0039] Furthermore, a sensitive position contact sensor is provided in the vertical direction of the fixture assembly 6. The position contact sensor is connected to the output end of the rotation mechanism 305 and is used to detect the position change of the grabbed lens or FA. According to the product process requirements, the position distance between the array lens and the FA coupling from the bottom substrate is only about 20 microns, and the repeat accuracy requirement is 5 microns; the highly sensitive position sensor can more accurately move the array lens and the FA to the theoretical coupling position.

[0040] The two loading mechanisms 3 of the device, where the one located on the left side of the stage mechanism 1 is used to grab and transport the lens to the coupling position, and the one located on the right side is used to transport the FA to the coupling position. Subsequently, position adjustment is performed to ensure qualified coupling, and the standard for qualified coupling is that all channel values reach the qualified range.

[0041] As Figure 7 shown, the fixture assembly 6 for grabbing the lens includes lens jaws 601, and a lens suction nozzle 602 is provided in the middle of the lens jaws 601; both the lens jaws 601 and the stage jaws 207 are prior arts, and their two jaws can be opened and closed to complete the grabbing and placing work; while the lens suction nozzle 602 adsorbs the lens by the principle of vacuum negative pressure.

[0042] The lens suction nozzle 602 is located in the middle position of the lens jaws 601 and above the lens, which can not only achieve limit but also ensure that it will not fall during the transportation process.

[0043] As Figure 6 shown, the fixture assembly 6 for fixing the FA includes an FA suction nozzle 603, and its working principle is the same as that of the lens suction nozzle 602. The FA suction nozzle 603 can suck the FA to achieve fixation; before the device works, the FA needs to be placed in the fixture assembly 6 of the right loading mechanism 3 for fixation, that is, the FA is adsorbed by the FA suction nozzle 603, and its pigtail interface is connected to the optical power meter interface. During the coupling process, the coupling can be adjusted through the reading value of the optical power meter, that is, the corresponding positions of the lens and the FA are adjusted, and finally ensure that all channel values reach the qualified range.

[0044] Working principle: The multiple independent lenses in the multi-channel of the optical module are changed into an array lens, and the loading mechanisms 3 are respectively built on the left and right sides of the stage mechanism 1. In the middle is the coupling stage 101, which contains TEC sheets, heat dissipation devices and other components to meet the production requirements; the front and back sides of the coupling stage 101 are product trays to realize automatic loading and unloading, and there is also a probe card for power supply on the left side. The back side is the transport and dispensing mechanism 2, which has the functions of automatic loading, dispensing and visual inspection; a first visual component 106 is provided on the side of the coupling stage 101 close to the lens fixture 103, which is used for position calibration of the array lens and FA, and alignment of the array lens, FA and laser 402.

[0045] After the stage clamp 207 carries the optical module substrate 4 from the substrate fixture 102 to the coupling stage 101 , the corresponding fixture assembly 6 carries the array lens and FA on the lens fixture 103 to the coupling position in sequence for synchronous coupling mounting. Embodiment 2

[0046] On the basis of the first embodiment, the present invention further proposes a method for synchronously coupling an array lens and FA, comprising the following steps.

[0047] Before the equipment is operated, the substrate fixture 102 carrying the optical module substrate 4 and the lens fixture 103 carrying the array lens are placed on both sides of the coupling platform 101 respectively, and then the FA is placed in the clamp assembly 6 of the right feeding mechanism 3 for fixation, and its pigtail interface is connected to the optical power meter interface.

[0048] Feeding platforms are arranged on both sides of the coupling platform 101, and the substrate fixture 102 and the lens fixture 103 are placed on the feeding platforms and adopt a detachable structure for easy replacement; the fixture assembly 6 for fixing FA is the FA nozzle 603, and the optical power meter is an instrument for measuring optical power. The reading of the optical power meter can be used to identify whether the optical channel is qualified or not.

[0049] After the preliminary preparations are completed, driven by the handling and dispensing mechanism 2, the stage clamp 207 grabs the optical module substrate 4 from the substrate fixture 102 and places it on the coupling stage 101, and then fixes and adjusts the angle. The handling and dispensing mechanism 2 can drive the stage clamp 207 to move along the X, Y and Z axes, so that it can grab the optical module substrate 4 and place it on the coupling stage 101. Under the guidance of the top-down visual camera (i.e., the second visual component 206), the rotation drive component 104 rotates around the Z axis to ensure that the light emitting direction of the laser 402 is along the X-axis direction after each material is placed on the coupling stage 101.

[0050] After the optical module substrate 4 is fixed on the coupling platform 101, its own position is adjusted by the rotating driving component 104 to ensure that the optical module substrate 4 can be in a horizontal position; a laser 402 corresponding to the number and position of the optical channel is arranged on the optical module substrate 4, and a Pad point 401 electrically connected to the laser 402 is arranged on one side.

[0051] After fixing the optical module substrate 4 on the coupling platform 101 and adjusting the position, the left loading mechanism 3 automatically grabs the array lens on the lens fixture 103 through its clamp assembly 6, and after adjusting the position by the first visual assembly 106, moves to the theoretical coupling position; wherein, the array lens is grabbed by the lens clamp 601 and the lens nozzle 602.

[0052] When the array lens moves to the theoretical coupling position, the right-side loading mechanism 3 adjusts the position of FA through the second visual component 206, and then moves it to the theoretical coupling position through the corresponding clamp component 6. During this process, FA is fixed by the FA suction nozzle 603.

[0053] When the array lens and FA are both in the theoretical coupling position, the probe card of the power supply probe mechanism 105 contacts the Pad point 401 on the optical module substrate 4 to supply power to the laser 402 and drive the laser 402 to emit light.

[0054] After the laser 402 emits light, the feeding mechanisms 3 on the left and right sides drive the array lens and FA into a coupling state, and the coupling is adjusted by the reading of the optical power meter. Based on the structure of the feeding mechanism 3 in the first embodiment, the array lens and FA both have 6 degrees of freedom in space, that is, the two can automatically adjust their positions as needed to achieve the best coupling position.

[0055] As described above, through the coupling algorithm and the image processing algorithm, the position of the array lens and the FA can be quickly adjusted, the position of the light outlet of the laser 402 in the identification module can be identified, and then the sensitive position contact sensors in the vertical direction of the two clamp components 6 can be used to achieve the alignment and coupling of the array lens, FA and the light outlet of the laser 402.

[0056] The specific process of coupling between the array lens and FA is as follows: 1. Each optical fiber tail of FA is connected to the optical power meter through a special connector, and the optical power value of each laser 402 after passing through the lens and optical fiber can be read in real time; 2. Keep FA still, adjust the angle of Rx of the array lens first, and automatically adjust the angle according to the real-time optical power values ​​of the two outermost optical fibers of FA. When the difference between their readings is the smallest, the difference in the angle between the array lens and the corresponding number of laser 402 outlets is within the flat range of the optical power value, which is the best coupling angle of the whole lens Rx. 3. According to the Rx angle coupling process, the Ry and Rz angles are coupled in sequence, and finally the angle connecting the array lens and the light outlet of the laser 402 is the optimal Rx, Ry, and Rz coupling angle. During coupling, the actual offset of the Rx, Ry, and Rz angles of each product is recorded, and the impact of the angles in the three directions on the optical power value is evaluated through the data of batch production. Then, only the angle direction with less impact is adjusted to a fixed angle, such as Rx, Ry is no longer coupled, and only Rz is coupled to improve the coupling efficiency; 4. Keep FA and the angle of the array lens unchanged, adjust the position of the array lens Px, and automatically adjust the distance between the lens and the light outlet of the laser 402 according to the real-time optical power values ​​of the two outermost optical fibers of FA. When the difference between their readings is the smallest, the distance between the array lens and the corresponding number of laser 402 light outlets is within the flat range of the optical power value, which is the best coupling position of the entire array lens Px; 5. According to the Px position coupling process, the Py and Pz positions are coupled in sequence, and finally the distance between the array lens and the light outlet of the laser 402 is the optimal Px, Py, and Pz coupling position.

[0057] Among them, Rx, Ry and Rz are rotations around the X, Y and Z axes respectively, and Px, Py and Pz are translations along the X, Y and Z axes respectively.

[0058] When the array lens and FA are coupled to each other, the glue dispensing component 5 dispenses glue to them, and the UV lamp 306 irradiates and cures them to complete the coupling mounting; the coupling qualified standard is that all channel values ​​are within the qualified range.

[0059] In summary, in order to simplify the production process and improve the production efficiency of optical modules, the present invention proposes a device and method for synchronously coupling array lenses and FA, which is a new automatic coupling process. The previous multi-channel lens coupling and mounting production process that required repeated multiple times is simplified to only one coupling and mounting. At the same time, the FA is also synchronously coupled during the lens coupling process, and the two processes are combined into one process, which greatly improves the production efficiency. This device can be widely promoted and is convenient for mass production in enterprises.
