Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, specifically to an automatic dispensing device for MT inserts. Background Technology

[0002] The MT ferrule is the core precision component in the MT type mechanically mated fiber optic connector. It is usually made of high-performance engineering plastics or ceramics and has a high-precision parallel array of micropores for fixing and aligning the fiber ribbon to achieve high-density, low-loss multi-core fiber connections. During its production, an adhesive dispensing process is required.

[0003] A search revealed a Chinese patent for a visual intelligent MT ferrule automatic dispensing device, publication number CN222890052U. The device includes a housing, which contains a transmission mechanism, a first fixture, a second fixture, a robotic arm mechanism, a dispensing mechanism, a CCD amplifier imaging mechanism, and a UV ultraviolet light source mechanism.

[0004] The above device, by setting up an air suction component, an air suction hole, a dispensing mechanism, a robotic arm mechanism, a CDD amplifier imaging mechanism, and a material groove, connects the fiber optic hole of the MT ferrule with the air suction hole. The air suction component absorbs the glue attached to the front end of the fiber optic hole into the fiber optic hole through the air suction hole, realizing visual intelligent dispensing with high dispensing efficiency and high precision. However, the insert is held and repositioned by grippers before and after dispensing. The robotic arm needs to move back and forth multiple times during the process, and can only hold a single insert for placement each time, resulting in low processing efficiency. Furthermore, the structure of the dispensing gun and mechanical grippers is relatively simple, serving only as a transfer function. Because the glue is sticky and the dispensing nozzle is small, the glue tends to accumulate in the middle, resulting in poor dispensing uniformity. Utility Model Content

[0005] The purpose of this invention is to provide an automatic dispensing device for MT ferrules, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An automatic dispensing device for MT ferrules includes a worktable. A Y-axis slide rail is provided on one side of the top of the worktable. An I-beam fixture is provided on the side of the top of the worktable away from the Y-axis slide rail. An X-axis slide rail is slidably mounted on the top of the Y-axis slide rail via a slider. A Z-axis slide rail is slidably mounted on the front end of the X-axis slide rail. A mounting frame is slidably mounted on the front end of the Z-axis slide rail. A dispensing cylinder is mounted on the front end of the mounting frame via an L-shaped connecting plate.

A stepper motor is installed at the end of the drive rod of the lifting cylinder through a connecting plate. A movable plate is installed at the bottom of the drive shaft of the stepper motor. Several gripper cylinders are movably installed at the front end of the movable plate through locking bolts and elastic mounting seats. The elastic mounting seats are used to elastically protect the grippers, and the gripper cylinders are used to clamp the dispensed core.

[0007] Preferably, when the drive push rod of the dispensing cylinder is retracted to its limit state, the top surface of the movable plate and the elastic mounting seat does not contact the bottom end of the needle of the dispensing syringe body.

[0008] Preferably, a glue suction component is provided on the top of the worktable near the Y-axis slide rail. The glue suction component has several placement blocks, which are equidistantly installed at the inner end of the Y-axis slide rail, and the distance between the placement blocks is adaptively matched with the distance between the gripper cylinders.

[0009] Preferably, a suction block is slidably mounted on the rear of the top of the placement block via a movable seat, a suction cylinder is mounted on the rear of the placement block, and the end of the drive rod of the suction cylinder is connected to the movable seat. A core placement groove is provided at the top of the placement block, and a suction port is provided at the end of the suction block away from the suction cylinder.

A drag chain is provided on the side of the Y-axis slide rail and the X-axis slide rail away from the center point of the worktable.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a lifting cylinder, an X-axis slide rail, a dispensing cylinder, a gripper cylinder, and a movable plate to work together. After dispensing, multiple inserts can be picked up and transferred at the same time by adjusting the position of the gripper cylinder, without having to clamp them back and forth multiple times. In addition, multiple placement blocks are set to facilitate the simultaneous placement and glue absorption of multiple picked inserts, which can improve processing efficiency. By setting up a stepper motor, a gripper cylinder, a movable plate, a dispensing syringe body, and a dispensing cylinder to work together, and because the gripper cylinder is located behind the dispensing syringe body, when dispensing another row of inserts, the clamped inserts will move back and forth to spread the glue evenly, thereby improving the dispensing effect, reducing the defect rate, and improving the overall performance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Combination Figures 1-5The MT insert automatic dispensing device includes a worktable 1. A Y-axis slide rail 2 is provided on one side of the top of the worktable 1. An I-beam fixture table 18 is provided on the side of the top of the worktable 1 away from the Y-axis slide rail 2. An X-axis slide rail is slidably mounted on the top of the Y-axis slide rail 2 via a slider. A Z-axis slide rail 3 is slidably mounted on the front end of the X-axis slide rail. A mounting frame is slidably mounted on the front end of the Z-axis slide rail 3. A dispensing cylinder 5 is mounted on the front end of the mounting frame via an L-shaped connecting plate. A dispensing syringe body 7 is mounted on the end of the drive push rod of the dispensing cylinder 5 via a syringe holder 6.

[0021] See Figure 2 , Figure 3 and Figure 4 Furthermore, a dispensing device is installed on the rearward side of the top of the worktable 1, away from the Y-axis slide rail 2. The dispensing tube of the dispensing device is connected to the top of the dispensing syringe body 7 through a sealing head. The dispensing device and the dispensing syringe body 7 cooperate to perform dispensing. A lifting cylinder 4 is installed at the center of the front end of the mounting frame. A stepper motor 8 is installed at the end of the drive push rod of the lifting cylinder 4 through a connecting plate. A movable plate 9 is installed at the bottom of the drive shaft of the stepper motor 8. Several gripper cylinders 11 are movably installed on the front end of the movable plate 9 through locking bolts and elastic mounting seats 10. The elastic mounting seats 10 are used to elastically protect the grippers. The top of the worktable 1 is located on the side of the Y-axis slide rail 2. The assembly includes a glue suction component with several placement blocks 15. These blocks 15 are equidistantly installed at the inner end of the Y-axis slide rail 2, and the distance between them is adaptively matched with the distance between several gripper cylinders 11. A glue suction block 16 is slidably mounted on the rear end of the top of each placement block 15 via a movable seat. A glue suction cylinder 17 is mounted on the rear end of each placement block 15, and the end of the drive rod of the glue suction cylinder 17 is connected to the movable seat. A core insertion slot is provided at the top of each placement block 15. A glue suction port is provided at the end of the glue suction block 16 away from the glue suction cylinder 17. A needle calibration seat 14, which is adaptively matched with the dispensing syringe body 7, is provided at the center of the top of the worktable 1.

[0022] Specifically, the Y-axis slide rail 2, Z-axis slide rail 3, and X-axis slide rail allow the dispensing syringe body 7 to be lowered to the needle calibration seat 14 for needle alignment. Subsequently, a placement plate containing the MT insert can be placed on the I-beam fixture table 18. After needle alignment, the Y-axis slide rail 2, Z-axis slide rail 3, and X-axis slide rails can move the dispensing syringe body 7 to the placement plate containing the MT insert for individual dispensing of the inserts. Since the gripper cylinder 11 is installed behind the dispensing syringe body 7 via multiple components, after dispensing one row of inserts, the Y-axis slide rail 2, Z-axis slide rail 3, and X-axis slide rails can control the gripper cylinder 11 to move to a suitable position to clamp the dispensed insert. The push rod of the dispensing cylinder 5 can then be controlled. The cylinder retracts to its limit and controls the drive shaft of the stepper motor 8 to rotate by one step angle to adjust the gripper cylinder 11 to rotate 90 degrees, thereby matching it with the MT ferrule placement port at the placement block 15. Subsequently, the Z-axis slide rail 3 can be controlled to descend, and the push rod of the lifting cylinder 4 can be controlled to extend, so that the glued ferrule can be placed at the placement block 15. Then, the glue suction cylinder 17 can drive the glue suction block 16 to move to the glue suction port position. At this time, because the glue suction block 16 is provided with a suction pipe on one side, and the suction pipe is connected to the glue suction port through the internal channel of the glue suction block 16, glue can be suctioned, so that the glue is evenly distributed in the ferrule. After the glue is suctioned, the gripper cylinder 11 can be controlled to descend to the appropriate position again, and after resetting the operation in reverse order, the MT ferrule can be clamped back to the original position and put down to complete the glue dispensing process. Example 2

[0023] See Figure 3 , Figure 4 and Figure 5 Furthermore, based on Embodiment 1, the following is further obtained: the gripper cylinder 11 is used to clamp the core after dispensing; the drive push rod of the dispensing cylinder 5 is retracted to its limit state; the top surfaces of the movable plate 9 and the elastic mounting seat 10 do not contact the bottom end of the needle of the dispensing syringe body 7; the front end of the mounting frame is equipped with a high-definition microscope 12 via a support rod, and the orientation of the high-definition microscope 12 is adapted to match the dispensing syringe body 7; a display screen 19 adapted to match the high-definition microscope 12 is installed above the worktable 1 via a support frame; an electrical control box 13 is provided at the rear end of the Z-axis slide rail 3; the electrical control box 13 is electrically connected to the stepper motor 8, the lifting cylinder 4, the dispensing cylinder 5, the gripper cylinder 11, and the high-definition microscope 12; and drag chains are provided on the side of the Y-axis slide rail 2 and the X-axis slide rail away from the center point of the worktable 1.

[0024] Specifically, during the dispensing process, multiple clamping cylinders 11 can simultaneously grip multiple inserts, which can then be transferred. The glue suction step can be temporarily omitted. At this time, the inserts are on the clamping cylinders 11. As the dispensing syringe body 7 moves to dispense glue to another row of inserts, the gripped inserts can be shaken to even out the glue inside. Furthermore, by controlling the stepper motor 8 to drive the shaft to rotate back and forth slightly, the shaking operation can be actively performed, which can effectively improve the uniformity of dispensing.

[0025] In actual operation, the steps of dispensing glue by cooperating with the dispensing syringe body 7 in the existing technology will not be described in detail here. By setting the Y-axis slide rail 2, Z-axis slide rail 3 and X-axis slide rail, the dispensing syringe body 7 can be moved down to the needle calibration seat 14 for needle alignment. Subsequently, the placement plate containing the MT insert can be placed on the I-beam fixture table 18 so that after needle alignment, the dispensing syringe body 7 can be moved to the placement plate of the MT insert by the sequential action of the Y-axis slide rail 2, Z-axis slide rail 3 and X-axis slide rail so that the insert on it can be glued one by one. Because the gripper cylinder 11 is installed behind the dispensing syringe body 7 through multiple components, after one row of inserts is dispensed, the gripper cylinder 11 can be moved to a suitable position by the sequential action of the Y-axis slide rail 2, Z-axis slide rail 3, and X-axis slide rail to grip the dispensed inserts. Subsequently, the push rod of the dispensing cylinder 5 can be retracted to its limit, and the drive shaft of the stepper motor 8 can be rotated by one step angle to adjust the gripper cylinder 11 to rotate 90 degrees, thereby matching the MT insert placement port at the placement block 15. Subsequently, the Z-axis slide rail 3 can be controlled to descend, and the push rod of the lifting cylinder 4 can be controlled to extend, so that the glued insert can be placed at the placement block 15. Then, the glue suction cylinder 17 can drive the glue suction block 16 to move to the glue suction port position. At this time, because the glue suction block 16 is provided with a suction pipe on one side, and the suction pipe is connected to the glue suction port through the internal channel of the glue suction block 16, glue can be suctioned so that the glue is evenly distributed in the insert. After the glue is suctioned, the gripper cylinder 11 can be controlled to descend to the appropriate position again, and after resetting in the reverse order, the MT insert can be clamped back to the original position and put down to complete the glue dispensing process. This step requires ensuring that the telescopic push rods of the glue dispensing cylinder 5 and the lifting cylinder 4 retract and extend at appropriate distances to avoid collisions. During the dispensing process, multiple clamping cylinders 11 can simultaneously grip multiple inserts, which can then be transferred. The subsequent glue suction step can be temporarily omitted. While the inserts are on the clamping cylinders 11, the dispensing syringe body 7 moves to dispense glue to another row of inserts, causing the gripped inserts to shake, thus evenly dispensing the glue. Furthermore, by controlling the stepper motor 8 to drive the shaft to rotate back and forth slightly, the shaking operation can be actively performed, effectively improving the uniformity of the dispensing. During the dispensing process, because the MT insert dispensing port is small, the high-definition microscope 12, display screen 19, and dispensing syringe body 7 can be used to photograph the dispensing syringe body 7 for personnel observation. Furthermore, the aforementioned consumable components are connected by internal hex bolts, which can be replaced in a timely manner after damage. At the same time, the position of the gripper cylinder 11 can be finely adjusted. It is not limited to one or two working conditions, and personnel can make reasonable selections and configurations. Therefore, no further details are provided, and the technical solution described in this embodiment shall prevail. Furthermore, the display and control components and modules used in the aforementioned movable slide rails such as the needle calibration seat 14, glue suction cylinder 17, lifting cylinder 4, dispensing cylinder 5, and gripper cylinder 11 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and does not need to be elaborated. The content protected by this utility model does not involve the improvement of software and methods. Moreover, this utility model is mainly used to protect mechanical mechanisms, so this utility model will not explain the control method and circuit connection in detail.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
