Description

Technical Field

[0001] This invention relates to the field of fiber optic ring manufacturing for fiber optic gyroscopes, and in particular to an adhesive bonding device for assembling fiber optic rings. Background Technology

[0002] As the core component of a fiber optic gyroscope, the fiber optic ring directly determines its performance. To ensure the reliability and mechanical properties of the fiber optic ring, it is bonded to a metal housing base using structural adhesive. However, under varying temperature conditions, the different coefficients of linear expansion between materials generate additional stress, affecting light transmission within the fiber core and leading to phase errors. This places higher demands on the uniformity of the adhesive distribution; localized non-uniformity in the adhesive increases additional stress, further amplifying the phase error of the fiber optic ring and ultimately degrading its performance, and even the performance of the fiber optic gyroscope itself.

[0003] The adhesive application step before fiber optic ring bonding mainly refers to using structural adhesive to bond the fiber optic ring end face to the metal housing base. Currently, this step is mostly done manually using tools to apply the adhesive. After the adhesive is spread over a certain area, it is weighed to confirm the amount, and then removed or replenished according to the principle of "removing excess and adding less." Only after the amount of adhesive meets the requirements is the fiber optic ring bonded to the housing base. With this method, it is difficult to detect the uniformity of adhesive distribution, and the uniformity and consistency of adhesive application are hard to guarantee.

[0004] In addition, from a process perspective, the current adhesive coating and ring bonding processes are separate. After the adhesive coating is completed, the shell needs to be removed, and the amount of adhesive is confirmed by weighing with an electronic scale before the ring is placed back on to complete the bonding. The numerous uncertainties brought about by the manual operation of multiple processes result in poor consistency of the finished fiber optic rings. The entire process involves multiple placement and removal of the shell and placement of the ring, and repeated positioning will also result in a certain loss of accuracy. Summary of the Invention

Detailed Implementation

[0028] Example 1:

[0029] An automatic adhesive application device for bonding fiber optic rings includes an adhesive application motion control system, an adhesive dispensing system, an air pressure control system, a vacuum system, an adhesive dispensing valve control system, an adhesive dispensing valve, a housing gripping device, a vision system, a handheld programmer, and a housing positioning sleeve. The adhesive application motion control system comprises a four-axis motion platform (X-axis, Y-axis, Z-axis, and R-axis). The device can complete the adhesive application process according to a set trajectory and adhesive quantity parameters.

[0030] 1. This automatic adhesive application device for fiber optic ring bonding includes a four-axis motion platform, which comprises four-axis servo motors (X-axis, Y-axis, Z-axis, and R-axis), a motion controller, and a handheld programmer 15. A housing positioning sleeve 16 is located directly above the R-axis for placing the matching fiber optic ring. A pressure sensor 5 is connected below the housing positioning sleeve to monitor the amount of adhesive applied. The Z-axis is connected to a dispensing valve 4, a mixer 13, and a first adhesive tube 11 and a second adhesive tube 12. The handheld programmer 15 can program motion or import external programs via a USB interface 19 into the motion controller, which then controls the X-axis, Y-axis, Z-axis, and R-axis servo motors to control the adhesive application path with high precision, high efficiency, and high accuracy.

[0031] 2. The motion platform of this automatic glue application device for fiber optic ring bonding has a built-in motion controller, glue quantity control system, AB two-component glue mixing system, and vacuum system. After being encapsulated in a metal casing, it has a main power switch 25, an emergency stop button 21, a start button 24, a jog glue dispensing button 22, a stop button 23, a glue delivery air pressure control knob 10, a total air pressure control knob 17, a buzzer 26, a human-machine interface 9, a USB interface 19, and a handheld programmer communication interface 20.

[0032] 3. The glue application control system of this automatic glue application device for fiber optic ring bonding includes a dispensing valve control system, a dispensing valve 4, a glue delivery control system, a first glue tube 11, a second glue tube 12, an AB component glue mixing system 13, a glue quantity monitoring system, a pressure sensor 5, and a liquid level sensor 3. The dispensing valve is fixed to the mounting plate of the Z-axis moving guide rail by screws. The dispensing valve has four interfaces, which are connected to the mixing system, the glue application needle 26, and the dispensing valve control system, respectively. After setting the program path using the handheld programmer 15, the glue quantity is set and the corresponding product is selected through the human-machine interface 9. The human-machine interface 9 imports the selection result into the PLC. The PLC uses the selection result to retrieve the glue delivery parameters to control the proportional valve of the glue delivery air pressure. During the glue application process, the glue quantity can also be transmitted to the PLC based on the data monitored by the pressure sensor 5. The PLC adjusts the proportional valve of the glue delivery air pressure to correct for changes in the dispensing volume caused by head difference and viscosity variations. This mode can also be used to automatically find the control air pressure for applying glue to new products. Simply place the housing on the tooling 16, input the required amount of glue and related glue parameters, and the PLC will automatically find the corresponding control air pressure for glue application based on the glue application time and save the relevant parameters. The dispensing valve 4 communicates with the PLC through the motion controller, and the PLC sends a signal to the solenoid valve. The solenoid valve controls the movement of the cylinder of the dispensing valve 4. The dispensing valve 4 precisely controls the glue dispensing and closing through the movement of the cylinder. The amount of glue is monitored by the liquid level sensor 3. When the amount of glue is less than the set value, the liquid level sensor 3 sends a signal to the PLC. The PLC reminds the operator to add glue through the human-machine interface 9 and the buzzer 26. When adding glue, the glue supply air pressure is turned off by the glue supply air pressure control knob 10. Then, glue is added to the glue with insufficient amount. After adding, the glue supply air pressure control knob 10 is turned on. When the glue in the first glue tube 11 and the second glue tube 12 is viscous and has air bubbles that are difficult to remove, the vacuum generator can also be controlled through the human-machine interface 9 to perform appropriate vacuuming of the glue tubes to accelerate the removal of air bubbles in the glue.

[0033] 4. In the automatic adhesive mixing device for bonding optical fiber rings, the mixing ratio of components A and B can be adjusted through the human-machine interface 9. The viscosity and ratio of the adhesive components A and B are input into the human-machine interface 9, and the human-machine interface 9 imports the information into the PLC. The PLC controls the mixing ratio of components A and B by calculating and adjusting the air pressure ratio of the first adhesive tube 11 and the second adhesive tube 12 through the program. The two components of adhesive are mixed evenly through the adhesive mixer 13. The adhesive mixer 13 is connected to the dispensing valve 4 and is applied to the base of the optical fiber ring housing 27 through the dispensing valve 4.

[0034] 5. After the automatic glue application device for the fiber optic ring is started, the pressure sensor 5 monitors whether there is a housing on the fixture. When there is no housing, the robotic arm locates the housing position through the vision system 18, and then the soft multi-axis robot 14 with pressure monitoring grabs the housing onto the fixture 16 with appropriate force. After the vision system 18 identifies the housing features, the multi-axis robot accurately places the housing in the fixture through memory positioning and the vision system 18. After the glue application is completed, the robotic arm guides the multi-axis robot 14 through the vision system 18 to pick up the housing and place it in a suitable range position.

[0035] Example 2:

[0036] like Figure 1-5 Among them, a gluing and bonding device for assembling fiber optic rings includes a machine base. The machine base is provided with a first moving shaft 1, a second moving shaft 2 and a third moving shaft 7 arranged perpendicularly to each other. It is also provided with a housing positioning sleeve 16 for placing the fiber optic ring housing 27. The second moving shaft 2 can move vertically. The second moving shaft 2 is provided with a first glue tube 11 and a second glue tube 12. The lower ends of the first glue tube 11 and the second glue tube 12 are connected to a glue mixer 13. The lower end of the glue mixer 13 is connected to a glue dispensing valve 4. The glue dispensing valve 4 is used to apply glue into the fiber optic ring housing 27.

[0037] The first moving axis 1, the second moving axis 2 and the third moving axis 7 are linear linear motion modules. The internal structure is a motor, guide rail and lead screw structure or a motor, guide rail and synchronous belt structure. The fiber optic ring housing 27 is removed and placed in the housing positioning sleeve 16 for positioning. The external controller drives and controls the movement of each axis.

[0038] According to the pre-written program, the glue applicator at the lower end of the glue dispensing valve 4 is moved to the concave cavity of the fiber optic ring housing 27 near the bottom surface. The glue in the first glue tube 11 and the second glue tube 12 is driven by air pressure to be mixed in the glue mixer 13 and then enters the glue dispensing valve 4. The air pressure controls the glue dispensing valve 4 to open, and glue is dispensed from the lower end of the glue dispensing valve 4. The first moving shaft 1 and the third moving shaft 7 follow the circular interpolation path and fit into a circle to apply glue to the bottom end of the fiber optic ring housing 27. The glue is distributed in multiple concentric rings.

[0039] Remove the fiber optic ring 28 and place it inside the fiber optic ring housing 27 to complete the ring bonding operation.

[0040] After glue A and glue B are added to the first glue tube 11 and the second glue tube 12, the air vent at the top is evacuated to form a negative pressure and maintain it for a period of time to expel air bubbles from the glue.

[0041] The mixer 13 is equipped with a spiral rod, which forms a spiral channel with the side wall of the mixer 13, so that the AB glue is automatically mixed evenly when it enters.

[0042] In a preferred embodiment, a rotating device 8 is also provided, on which multiple outstretched arms 801 are provided, each outstretched arm 801 is provided with a pressure sensor 5, and the upper end of the pressure sensor 5 is provided with a housing positioning sleeve 16. A multi-axis robot 14 is also provided on one side of the machine.

[0043] Pressure sensor 5 is used to monitor the real-time glue application flow rate and final glue application weight, serving as an online weighing function. It can also be used as a sensor to monitor whether the housing positioning sleeve 16 has been filled with material.

[0044] The rotating device 8 can be used to form a multi-station structure. While the glue application is being performed, the multi-axis robot 14 can be used to load the fiber optic ring housing 27 onto another outstretched arm 801, thereby improving the overall glue application efficiency.

[0045] The multi-axis robot 14 is preferably a four-axis horizontal multi-joint robot.

[0046] Since manual placement of the housing and ring is inefficient, inaccurate, and inconsistent, a multi-axis robot 14 can automatically grasp the fiber optic ring housing 27 and place it on the housing positioning sleeve 16, and then grasp the fiber optic ring 28 and place it inside the fiber optic ring housing 27, thus automatically completing the entire ring bonding process.

[0047] A vision system 18 can be installed on the multi-axis robot 14 to intelligently identify the position of each component and realize intelligent production.

[0048] In a preferred embodiment, a feeding device 6 is also provided. The feeding device 6 includes a first storage cylinder 601, a second storage cylinder 602, and a feeder 603. The first storage cylinder 601 is used for vertically stacking the fiber optic ring housing 27, and the second storage cylinder 602 is used for vertically stacking the fiber optic ring 28. There are at least four outriggers 801. The feeder 603 includes a slidable lifting frame 606. The lifting frame 606 is provided with a rotatable rotating arm 605. The end of the rotating arm 605 is provided with a suction cup device 604, which is used to pick up the fiber optic ring housing 27 and the fiber optic ring 28.

[0049] The fiber optic ring housing 27 without the fiber optic ring 28 is hollow in the middle, and lateral clamping can easily cause deformation. The fiber optic ring 28 has a small inner hole and usually exits the fiber from the outside, so lateral clamping is also difficult to achieve. Therefore, end-face suction is more reasonable.

[0050] The rotating device 8 includes a geared motor for rotation, and a central connecting plate is provided at the end of the motor shaft. Each outstretched arm 801 is connected to the central connecting plate.

[0051] The rotating device 8 is preferably a four-station device, namely a housing placement station, a housing gluing station, a ring placement station, and a material unloading station. The material unloading station is located near the multi-axis robot 14. The first storage cylinder 601 and the second storage cylinder 602 are respectively placed on both sides of the feeder 603. The overall process flow is as follows: the rotating arm 605 of the feeder 603 rotates to the top of the first storage cylinder 601, picks up the fiber optic ring housing 27, and then rotates to the housing placement station to place the fiber optic ring housing 27 into the housing positioning sleeve 16 on the outstretched arm 801.

[0052] Rotating device 8 rotates, rotating fiber ring housing 27 to the glue application station. First moving shaft 1, second moving shaft 2 and third moving shaft 7 work, glue dispensing valve 4 is opened to apply glue into fiber ring housing 27. After glue application is completed, glue dispensing valve 4 is closed, and first moving shaft 1, second moving shaft 2 and third moving shaft 7 are reset.

[0053] The rotating device 8 rotates again, rotating the fiber optic ring housing 27 to the ring placement position. At the same time, the rotating arm 605 of the feeder 603 rotates to the top of the second storage cylinder 602 to pick up the fiber optic ring 28, and rotates to the ring placement position, pressing the fiber optic ring 28 down to the bottom of the fiber optic ring housing 27.

[0054] The rotating device 8 rotates again, moving the already installed fiber optic ring to the unloading station, where the multi-axis robot 14 picks up the fiber optic ring and places it into the finished product buffer area.

[0055] The multi-axis robot 14 uses a flexible claw to avoid damaging the gripped parts. Because the multi-axis robot 14 has a wide coverage area, it can be used to replace the first storage cylinder 601 and the second storage cylinder 602, provided that the feeding cycle time is met.

[0056] In a preferred embodiment, the first storage cylinder 601 includes an upper cylinder body, and an annular cavity 612 is provided inside the upper cylinder body. The annular cavity 612 is used to stack and place the optical fiber ring housing 27. The annular cavity 612 is provided with a lifting ring plate 608 that can slide up and down, and the lifting ring plate 608 lifts up the optical fiber ring housing 27.

[0057] In a preferred embodiment, the annular cavity 612 is provided with an outer clamping wall and an inner clamping wall on both sides. The inner clamping wall is provided with an annular groove 613. The side wall of the annular groove 613 near the annular cavity 612 is provided with a plurality of connecting holes 617 evenly distributed in the circumferential direction. The opening of the connecting holes 617 is covered with an elastic membrane 615. The annular groove 613 is also provided with a vent hole 616. The opening of the annular groove 613 is provided with a cap 614.

[0058] Since the fiber optic ring housing 27 and fiber optic ring 28 are relatively fragile, a gentler positioning method is required. The connecting hole 617 is positioned at the uppermost end of the ring cavity 612, preferably in two rings. An air valve controls the vent hole 616 to inflate the ring groove 613, forcing the elastic membrane 615 to deform into the connecting hole 617 until it protrudes beyond the outer side of the inner clamping wall. The protrusion presses against the inner wall of the fiber optic ring housing 27 or fiber optic ring 28. Because the elastic membrane 615 is of uniform material, and given good roundness of the inner clamping wall, the fiber optic ring housing 27 can achieve self-centering, preparing for the suction cup device 604 to pick it up.

[0059] In the preferred embodiment, a fixed frame 607 is provided at the lower end of the upper cylinder of the first storage cylinder 601. A top frame 609 is provided inside the fixed frame 607. The top frame 609 is connected to the lifting ring plate 608. A nut 610 is provided on the top frame 609. A lead screw 611 is also provided. The lead screw 611 is sleeved with the nut 610. A motor is provided at the end of the lead screw 611.

[0060] The lead screw 611 is rotated by a stepper motor or servo motor to adjust the height of the lifting ring 608 by the top frame 609. Each time a fiber optic ring housing 27 is removed, the lifting ring 608 is raised by the thickness of one fiber optic ring housing 27 until all fiber optic ring housings 27 are removed.

[0061] The upper part of the first storage cylinder 601 can be removed as a whole for easy replacement. After the fiber optic ring housing 27 is filled, it can be placed on the fixing frame 607 as a whole.

[0062] In the preferred embodiment, the upper cylinder of the first storage cylinder 601 is detachable from the fixing frame 607.

[0063] In the preferred embodiment, the first storage cylinder 601 and the second storage cylinder 602 have the same structure.

[0064] In a preferred embodiment, a flexible layer 618 is provided on the outer side of the inner wall of the first storage cylinder 601 and the second storage cylinder 602.

[0065] The gap between the fiber optic ring or housing and the outer clamping wall is large, while the gap between it and the inner clamping wall is small. Therefore, a flexible layer 618 is used on the outside of the inner clamping wall to prevent the fiber optic ring or housing and the inner side of the outer clamping wall from being scratched when loading or lifting materials.

[0066] In the preferred embodiment, the lower end of the lifting frame 606 is provided with a rack 619 and a guide rod 622, and also with a mounting base 620. The mounting base 620 is provided with a guide sleeve and a gear 621. The gear 621 meshes with the rack 619, and the guide rod 622 is slidably sleeved with the guide sleeve.

[0067] Both the rotating arm 605 and the gear 621 are equipped with a reduction motor.

[0068] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
