[0040] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0041] WDM devices are devices that synthesize and separate optical wavelengths. The synthesizer is called a combiner, and the separator is called a wavelength splitter. Its structure is generally composed of two major parts, namely the reflector with wavelength separation and filtering function and the collimator with light collimation function. Among them, the reflector includes a filter, a G-lens (self-focusing lens) and a dual-fiber pigtail. The reflector mainly uses the interference principle of light to obtain the transmission of the spectrum of the specified wavelength, and reflects and absorbs the spectrum of the remaining wavelengths. The filter is deposited on the optical substrate with thin films of different refractive indices by a vacuum coating machine, thereby achieving different optical effects. When mixed light of multiple wavelengths passes through the filter, interference effect occurs due to different refractive indices, resulting in a very high transmittance of light of a specific wavelength and reflection and absorption of light of other wavelengths.

[0042] In the production process of the above-mentioned reflective end, the filter and the G-lens are first combined into a diaphragm head through a patch process, and then coupled with the dual-fiber pigtail and encapsulated. The operation process between the diaphragm head and the dual-fiber pigtail is called the encapsulation process.

[0043] In the existing WDM reflector end encapsulation process, most actions need to be performed under a 40x stereo microscope. After manually placing the membrane head and dual-fiber pigtail on the shelf, the technician needs to follow up in real time to confirm the product's docking coupling parameters and adjust the materials to ensure that the coupling parameters are qualified. After the technician confirms that the docking coupling parameters are qualified, it is necessary to use a dispensing needle to manually apply glue on the docking surface of the membrane head and the dual-fiber pigtail for a week. After the glue is applied, the ultraviolet light source is manually pushed in for irradiation and curing. In this encapsulation process, manual workstations are used, and there are too many operations that require manual participation online, resulting in low production efficiency. At the same time, it is also easy to have poor consistency problems caused by human factors.

[0044] In view of this, an embodiment of the present application proposes a rubber encapsulation device to effectively solve the aforementioned problem.

[0045] See also Figures 1 to 6 As shown, an embodiment of the present application discloses a rubber coating device, including a loading module 100 , a pigtail coupling module 200 , a rotary rubber coating module 400 , and a visual and baking module 500 .

[0046] Specifically, the loading module 100 includes a first clamping assembly 140, which is used to clamp the first workpiece 1; the pigtail coupling module 200 includes a second clamping assembly 230, which is arranged on one side of the first clamping assembly 140, and the second clamping assembly 230 is used to clamp the second workpiece 2; the rotating glue-coating module 400 includes a rotating hollow platform assembly 420 and a dispensing valve assembly 450, and the dispensing valve assembly 450 is installed on the rotating hollow platform assembly 420, and the rotating hollow platform assembly 420 is used to drive the dispensing valve assembly 450 to rotate circumferentially around the joint between the first workpiece 1 and the second workpiece 2, and the dispensing valve assembly 450 is used to perform glue-coating on the joint between the first workpiece 1 and the second workpiece 2; the visual module is used to identify and locate the first workpiece 1 and the second workpiece 2, and the baking module is used to solidify the adhesive on the first workpiece 1 and the second workpiece 2.

[0047] In some embodiments of the present application, the control module is used to control the loading module 100, the pigtail coupling module 200, the rotating encapsulation module 400, and the vision and baking module 500. The vision and baking module 500 includes a vision module and a baking module.

[0048] In the embodiment of the present application, the first workpiece 1 is installed on the first clamping assembly 140, and the second workpiece 2 is installed on the second clamping assembly 230. When clamping, the first workpiece 1 and the second workpiece 2 are arranged relative to each other and docked; then the first workpiece 1 and the second workpiece 2 are rotated and glued at the docking point by the rotating glue-coating module 400, and then the glue-coating is baked and fixed by the baking module to complete the glue-coating work. In this way, the glue-coating work can be completed by mechanical equipment, which helps to improve the efficiency of glue-coating and ensure the consistency of glue-coating; at the same time, in the embodiment of the present application, before glue-coating, the docking point of the first workpiece 1 and the second workpiece 2 is identified by the visual module, and the docking point of the first workpiece 1 and the second workpiece 2 can be accurately positioned to ensure that the dispensing valve assembly 450 can be aligned with the docking point of the first workpiece 1 and the second workpiece 2, thereby improving the quality of glue-coating.

[0049] In one embodiment of the present application, see Figure 1 , Figure 2 and Figure 3 The first workpiece 1 is a diaphragm head, which is clamped on the first clamping assembly 140; the second workpiece 2 is a dual-fiber pigtail, which is clamped on the second clamping assembly 230. One end of the diaphragm head and one end of the dual-fiber pigtail are arranged opposite to each other, that is, one end of the diaphragm head is located on the extended side of the dual-fiber pigtail. During the rubber coating, the rotating rubber coating module 400 applies an adhesive (such as glue, etc.) circumferentially at the joint of the diaphragm head and the dual-fiber pigtail to complete the rubber coating work.

[0050] Further, the diaphragm head has a first connection surface 101, and the second workpiece 2 has a second connection surface 201 that matches the first connection surface 101, and the second connection surface 201 is used to dock with the first connection surface 101. In practical applications, the first connection surface 101 and the second connection surface 201 are both inclined, and the inclination angle can be set accordingly as needed. For example, the angle between the first connection surface 101 and the extension direction of the diaphragm head is set to 8°.

[0051] In some embodiments of the present application, the encapsulation equipment further includes an optical power detection module 300, which is used to obtain the current optical path loss between the first workpiece 1 and the second workpiece 2. The optical power detection module 300 is connected to the control module to transmit the current optical path loss to the control module.

[0052] Specifically, the first workpiece 1 is a diaphragm head, and the second workpiece 2 is a dual-fiber pigtail. By using the optical power detection module 300 to obtain the current optical path loss of the connection between the diaphragm head and the dual-fiber pigtail and sending the obtained current optical path loss to the control module, the control module controls the pigtail coupling module 200 to operate, thereby adjusting the docking position and angle of the second workpiece 2 and the first workpiece 1 to obtain the position with the highest coupling efficiency and the lowest optical path loss, which helps to make the docking coupling parameters of the dual-fiber pigtail clamped in the second clamping component 230 and the diaphragm head clamped in the first clamping component 140 meet the product requirements, and then the control module controls the rotating rubber coating module 400 to rubberize the docking point of the diaphragm head and the dual-fiber pigtail. In this way, the coupling efficiency of the rubber-coated product can be high and the optical path loss can be small, which helps to improve the product quality.

[0053] In one possible implementation, see Figure 1 , Figure 2 and Figure 4 As shown, the optical power detection module 300 includes a second fixed base 310, an optical power meter 320 and an aligner 330. One end of the aligner 330 is connected to the light source line 3, the other end of the aligner 330 is connected to one of the optical fibers 4 of the dual-fiber pigtail, and the other optical fiber 4 of the dual-fiber pigtail is connected to the optical power meter 320. In this way, the optical path loss of the dual-fiber pigtail coupled with the diaphragm head can be detected by the optical power meter 320 and the aligner 330, which helps to adjust the dual-fiber pigtail to a docking position with a smaller optical path loss, thereby ensuring the quality of the product.

[0054] In some embodiments of the present application, see Figure 1 and Figure 6As shown, the visual module includes a first camera assembly 530 and a second camera assembly 540, and the first camera assembly 530 and the second camera assembly 540 are arranged crosswise. Specifically, the recognition areas of the first camera assembly 530 and the second camera assembly 540 are both aligned with the joint of the first workpiece 1 and the second workpiece 2. Using the cross-arranged first camera assembly 530 and the second camera assembly 540 to identify and locate the joint of the first workpiece 1 and the second workpiece 2 helps to improve the accuracy of recognition.

[0055] Furthermore, the vision and baking module 500 further includes a gantry assembly 510 and a motor module assembly 520. The gantry assembly 510 is mounted on one side of the first clamping assembly 140, and the motor module assembly is mounted on the gantry assembly 510. The motor module assembly can move on the gantry assembly 510. Among them, the first camera assembly 530 and the second camera assembly 540 are mounted on the motor module assembly, so that the first camera assembly 530 and the second camera assembly 540 can be moved along the gantry assembly 510 by the motor module assembly to adjust the shooting position.

[0056] The first camera assembly 530 and the second camera assembly 540 both include a CCD camera, which is used to photograph the joint between the diaphragm head and the dual-fiber pigtail. The CCD camera is electrically connected to the control module, and the photos taken by the CCD camera are sent to the control module in real time. The control module controls the pigtail coupling module 200 and the rotating glue-wrapping module 400 to move and adjust according to the photographed pictures, so that the second workpiece is correctly docked with the first workpiece 1, or the glue-dispensing valve assembly 450 is aligned with the joint between the diaphragm head and the dual-fiber pigtail, thereby helping to improve the quality of glue-wrapping.

[0057] In one possible implementation, see Figure 1 and Figure 6 , the first camera assembly 530 is arranged horizontally, and the second camera assembly 540 is arranged vertically. The first camera assembly 530 and the second camera assembly 540 are arranged on the same vertical plane, and the first camera assembly 530 and the second camera assembly 540 respectively shoot the joint of the membrane head and the dual-fiber pigtail from different angles, which helps to improve the accuracy of positioning.

[0058] It is worth to be understood that the first camera assembly 530 and the second camera assembly 540 may also be arranged at other angles.

[0059] It should be noted that the angle between the first camera assembly 530 and the second camera assembly 540 described above refers to the angle between the shooting direction of the first camera assembly 530 and the shooting direction of the second camera assembly 540 .

[0060] In some embodiments of the present application, see Figure 1 and Figure 3 The loading module 100 further includes a first fixed base 110, a first three-dimensional slide assembly 120 and a guide connection assembly 130. The first three-dimensional slide assembly 120 is mounted on the first fixed base 110, the guide connection assembly 130 is mounted on the first three-dimensional slide assembly 120, and the first clamping assembly 140 is mounted on the guide connection assembly 130. The first three-dimensional slide assembly 120 can move in the X direction, the Y direction and the Z direction, so that the first clamping assembly 140 can adjust the position in the X direction, the Y direction and the Z direction.

[0061] In some embodiments of this application, please continue to refer to Figure 1 and Figure 3 The guide connection assembly 130 includes a connection tube body, and the connection tube body has a hollow connection channel, and the connection channel is used to pass the cable. Specifically, the rotating hollow platform assembly 420 of the rotating rubber-coated module 400 is sleeved on the outer periphery of the connection tube body, and the rotating hollow platform assembly 420 rotates around the axis of the connection tube body. Since the cable passes through the connection channel in the connection tube body, the phenomenon of winding around the tube can be effectively avoided during the rotation of the rotating hollow platform assembly 420.

[0062] In some embodiments of the present application, see Figure 1 and Figure 4 , the pigtail coupling module 200 also includes a third fixed base 210 and a second three-dimensional slide assembly 220, the third fixed base 210 is arranged on one side of the first clamping assembly 140, the second three-dimensional slide is installed on the third fixed base 210, and the second clamping assembly 230 is installed on the second three-dimensional slide assembly 220. Among them, the second three-dimensional slide assembly 220 can move in the X direction, the Y direction and the Z direction. In this way, the second clamping assembly 230 installed on the second three-dimensional slide assembly 220 can be adjusted in the X direction, the Y direction and the Z direction, so that the dual-fiber pigtail can be better docked with the diaphragm head, thereby improving product quality.

[0063] In some embodiments of the present application, the baking module includes a point ultraviolet light source, which is used to emit ultraviolet light and irradiate the adhesive to cure the adhesive.

[0064] In some embodiments of the present application, see Figure 6 As shown, the baking module includes an ultraviolet protective cover, which is a non-enclosed structure in the circumferential direction of the ultraviolet light, that is, the ultraviolet protective cover has a gap in the circumferential direction where the ultraviolet light is emitted.

[0065] Specifically, the baking module is installed on one side of the second camera assembly 540, and the baking module is installed on the electric module assembly 520, and the baking module can be moved in the X direction and the Y direction through the electric module assembly. The dispensing valve assembly 450 applies the dispensing glue to the joint of the first workpiece 1 and the second workpiece 2, and then moves the baking module to the joint of the first workpiece 1 and the second workpiece 2.

[0066] It is worth understanding that when the baking module bakes the glue dispenser, the docking point is located on the side with the notch close to the UV protective cover. Then, the UV light source emits UV light to solidify the adhesive coated on the docking point. Among them, when the UV light source emits light, the glue dispenser valve assembly 450 is located on the side of the UV protective cover away from the notch, that is, part of the UV light emitted by the UV light source will be blocked by the UV protective cover and will not directly irradiate the glue dispenser valve assembly 450. In this way, it is avoided that the UV light directly irradiates the glue dispenser needle of the glue dispenser valve, thereby preventing the glue dispenser needle from being blocked by the UV light.

[0067] As a possible implementation method, the UV protection cover is specifically brown transparent plexiglass, which can not only facilitate employees to observe the irradiation process intuitively, but also help to block ultraviolet light.

[0068] It is worth to understand that the UV protection cover can also be transparent organic glass of other colors that can effectively reduce the penetration of ultraviolet light, which is not limited here.

[0069] In some embodiments of the present application, the dispensing valve assembly 450 includes a back-suction dispensing valve, which is used to control the delivery of the dispensing glue. Specifically, the back-suction dispensing valve adopts an upward back-suction glue-closing structure, which can stop the glue and instantly back-suction the glue, reduce the residual glue remaining on the dispensing needle, and effectively prevent glue leakage or wire drawing. The valve body of the dispensing valve is connected to the air inlet pipe, the air outlet pipe and the glue outlet pipe, and is connected with the circuit line of the feed electric slide 440 and then led out through the connection channel of the guide connection assembly 130 of the loading module 100.

[0070] See below Figures 1 to 6 The rubber coating equipment of the embodiment of the present application is described in detail with a specific embodiment. It should be noted that this embodiment is only an exemplary description and should not be understood as a limitation on the rubber coating equipment of the embodiment of the present application.

[0071] See also Figures 1 to 6 As shown, the glue encapsulation equipment includes a loading module 100, a pigtail coupling module 200, an optical power detection module 300, a rotary glue encapsulation module 400, a vision and baking module 500 and a control module.

[0072] in:

[0073] The loading module 100 is used for the loading and clamping of the diaphragm head, the center alignment adjustment of the rotation center of the loading module 100, and the anti-winding and leading out of the air pipe and the circuit line. Specifically, the loading module 100 includes a first fixed base 110, a first three-dimensional slide assembly 120, a guide connection assembly 130 and a first clamping assembly 140. By controlling the fine-tuning movement of the first three-dimensional slide assembly 120 in the X direction, the Y direction and the Z direction, the center line of the loaded diaphragm head is aligned with the rotation center. During rotation, the air pipe and the circuit line are led out through the connection channel of the guide connection assembly 130 to prevent the phenomenon of winding around the pipe and the wire during rotation.

[0074] The pigtail coupling module 200 is used for loading and clamping the dual-fiber pigtail and controlling the dual-fiber pigtail to automatically complete the coupling and dimming with the diaphragm head. Specifically, the pigtail coupling module 200 includes a third fixed base 210, a second three-dimensional slide assembly 220, and a second clamping assembly 230. The control module drives the second three-dimensional slide assembly 220 to perform coupling and dimming, and obtains the position coordinates of the second three-dimensional slide assembly 220 when the coupling efficiency is the highest and the optical path loss is the lowest through the target search algorithm, and then controls the second three-dimensional slide assembly 220 to move to the specified coordinate position.

[0075] The optical power detection module 300 is used to obtain the current optical path loss and send the obtained optical path loss to the control module. Specifically, the optical power detection module 300 includes a second fixed base 310, an optical power meter 320 and an aligner 330. One end of the aligner 330 is connected to the light source line 3, and the other end is connected to one of the optical fibers 4 of the dual-fiber pigtail, so as to complete the docking of the light source line 3; and the other optical fiber 4 of the dual-fiber pigtail is connected to the optical power meter 320 to obtain the current optical path loss and send it back to the control module.

[0076] The rotating glue-coating module 400 is used to locate and identify the glue-coating position through a CCD camera for glue-coating. Specifically, the rotating glue-coating module 400 includes a translation electric slide 410, a rotating hollow platform assembly 420, a three-dimensional manual slide 430, a feeding electric slide 440 and a dispensing valve assembly 450. The three-dimensional manual slide 430 is used to adjust the alignment of the dispensing valve assembly 450 and the dispensing rotation center. The dispensing valve assembly 450 is a back-suction dispensing valve, and the dispensing valve assembly 450 is symmetrically distributed on both sides of the rotating arm of the rotating hollow platform assembly 420. Among them, the back-suction dispensing valve adopts an upward back-suction glue-closing structure, so that the glue is stopped and the glue is instantly back-sucked and cut off, reducing the residual glue on the remaining needle tip and preventing glue leakage and wire drawing. The dispensing valve body is connected to the air inlet pipe, the air outlet pipe and the glue outlet pipe, and is connected with the circuit line of the feeding electric slide 440 and then led out through the hollow connecting channel.

[0077] The vision and baking module 500 is used to assist the loading of the material at an angle of 8 degrees, identify the dispensing position, UV curing and the detection and judgment of the size of the rubber package. The vision and baking module 500 includes a gantry assembly 510, an electric module assembly 520, a first camera assembly 530, a second camera assembly 540 and a baking assembly 550. The first camera assembly 530 and the second camera assembly 540 both include CCD cameras, and their CCD cameras are both equipped with a two-dimensional manual slide for shooting adjustment; the baking assembly 550 controls the point ultraviolet light source to move up and down through a precision slide cylinder for irradiation and curing, and the point light source is semi-enclosed and fixed by a UV protective cover. Furthermore, the UV protective cover is a brown transparent organic glass, which can not only facilitate employees to observe the irradiation process intuitively, but also effectively block ultraviolet light, while isolating the dispensing needle to prevent ultraviolet light from reflecting and irradiating the needle and causing glue blockage.

[0078] The control module is connected to the pigtail coupling module 200, the optical power detection module 300, the rotary rubber coating module 400, and the vision and baking module 500. The control module is used to control the movement and information processing of the aforementioned modules. The control module is controlled by PC programming. The PC is connected to the motor control box through a signal adapter cable to control the programmable motion control card. The programmable motion control card is equipped with a command compiler, a high-speed A / D converter, and a multi-axis motion controller. The motion control card drives the motor module and the electric slide to complete the specified movement.

[0079] Specifically, the first clamping component 140 of the loading module 100 passes through the hollow hole of the rotating hollow platform component 420 of the rotating rubber-coating module 400, and adjusts the alignment with the rotating hollow platform component 420 of the rotating rubber-coating module 400 through its three-dimensional manual slide 430. The air pipe of the suction dispensing valve and the circuit line of the electric slide of the rotating rubber-coating module 400 are both led out through the hollow connecting channel of the guide connecting component 130 of the loading module 100, and then respectively connected to the main air source and the control module.

[0080] When in use, when the staff puts the film head and the dual-fiber pigtail on the shelf respectively, they synchronously adjust the oblique octave surfaces of the two materials to be completely flush by observing the real-time imaging images of the horizontal CCD camera of the first camera assembly 530 and the vertical CCD camera of the second camera assembly 540. At this time, the two materials are completely attached together, and after the automatic coupling is turned on, the pigtail coupling module 200 controls the dual-fiber pigtail to move to the position with the minimum optical path loss and the highest coupling efficiency.

[0081] During the above automatic coupling process, the motion control card drives the second three-dimensional electric slide assembly of the pigtail coupling module 200 to adjust and move in the plane and longitudinal direction. At the same time, the control module sends a communication instruction to the optical power meter 320 to start the high-speed power acquisition mode, and continuously sends the acquired optical path loss back to the control module, and stores it in the database for corresponding calculations. Then, according to the position coordinates of the current minimum optical path loss, the second three-dimensional electric slide is controlled to move to the specified coordinate position. In this embodiment, combined with high-speed acquisition and target search algorithms, the average efficiency of system dimming is 12 seconds per unit, which effectively improves the dimming efficiency.

[0082] Furthermore, the rotating glue-coating module 400 has a rotating arm 460, the initial position of which is 45° clockwise, and the vertical CCD camera assembly is located directly above the loading position, which is convenient for employees to perform position identification and detection while loading. The rotating glue-coating module 400 is mainly connected to the PC through a motion control card, and the motion control card drives the translation electric slide 410, the rotating hollow platform assembly 420 and the feed electric slide 440 to realize the rotating glue-coating. The translation electric slide 410 is installed at the bottom of the rotating hollow platform assembly 420 to control the translation of the entire rotating glue-coating module 400, so that the glue dispensing valve moves to the glue-coating position. The rotating hollow platform assembly 420 is equipped with a servo motor, and two feed electric slides 440 are symmetrically distributed on both sides of its rotating arm 460. Before gluing, the horizontal CCD camera identifies the gluing position, and the translation electric slide 410 controls the glue dispensing valve assembly 450 to move to the gluing position to achieve precise positioning. At the same time, the motion control card drives the electric module assembly 520 of the vision and baking module 500 to move the first camera assembly 530 and the second camera assembly 540 to the right outside the rotation range. Then the feed electric slide 440 controls the radial movement of the glue dispensing valve so that the two symmetrically distributed glue dispensing needles are located on both sides of the gluing position. At this time, the I / O controller controls the glue dispensing valve to extrude the glue and starts to rotate clockwise for one circle, so that the gluing position of the diaphragm head and the dual-fiber pigtail is evenly coated with glue for one circle, thereby completing the rotation gluing operation.

[0083] During the above-mentioned visual recognition process, the computer software performs graphic recognition on the images taken by the horizontal CCD camera to confirm the encapsulation position of the diaphragm head and the dual-fiber pigtail.

[0084] Specifically, the vision and baking module 500 mainly drives the electric module assembly 520 and the precision slide cylinder of the baking assembly 550 installed on the gantry assembly 510 through the motion control card to perform overall displacement and lifting of the point light source. After the rotational glue encapsulation is completed, the rotating arm 460 rotates counterclockwise for one circle to reset to the 45° initial position, and the dispensing valve assembly 450 moves radially backward to reset, the electric module assembly 520 moves the baking assembly 550 to just above the glue encapsulation position, and then the precision slide cylinder descends, driving the ultraviolet point light source to descend to within 20mm of the glue encapsulation position, and ultraviolet irradiation curing is achieved through the I / O controller. After the curing operation is completed, the precision slide cylinder rises and resets, and the motion control card drives the electric module assembly 520 to reset to the initial position as a whole. Finally, the vertical CCD camera and the horizontal CCD camera take pictures after the glue encapsulation, and the computer software recognizes and determines the radial and width directions of the glue encapsulation size, so that employees can eliminate defective products according to the judgment results.

[0085] In one possible implementation of the present application, see 1 to Figure 7 The encapsulation process of the encapsulation equipment specifically includes the following steps:

[0094] S23. The control module controls the three-dimensional electric slide to move to the position coordinate according to the minimum optical path loss value found.

[0095] It should be noted that in order to find the minimum value of the optical path loss, steps S21-S22 need to be repeated several times. During this period, the power timer sends the acquired optical path loss to the control module at all times. The control module controls the three-dimensional electric slide to move to the position coordinate with the minimum optical path loss based on the obtained minimum value of the optical path loss.

[0096] Furthermore, the encapsulation further comprises the following sub-steps:

[0097] S31, the horizontal CCD camera recognizes the position of the rubber package and moves to the right out of the rotation range;

[0098] S32, the electric slide table 410 is moved in translation, driving the dispensing valve assembly 450 to move to the glue encapsulation position;
