Description

Technical Field

[0001] This utility model belongs to the field of optical device dispensing, specifically relating to an optical device dispensing mechanism and dispensing device. Background Technology

[0002] Optical devices are a crucial component of optical communication systems. During the manufacturing process of optical devices, especially certain specialized ones, adhesive dispensing is required at the soldering points for fixation. The existing technology uses adhesive dispensing devices to perform this process.

[0003] Existing dispensing devices include a dispensing mechanism, which comprises a needle, a syringe, and a drive structure. The syringe contains adhesive, and the needle is in communication with the syringe. The adhesive inside the syringe can enter the needle and be dispensed from the needle's outlet to the outside. For reference, see the prior art patent application number 202411011326.4, entitled "Automatic Dispensing Equipment for Optical Devices."

[0004] However, in existing dispensing mechanisms, because the syringe and needle are directly connected, the needle must be replaced along with the syringe when changing the syringe. After replacing the needle, it needs to be repositioned to ensure dispensing accuracy. This repositioning increases the operator's workload and reduces the dispensing efficiency of the mechanism. Utility Model Content

[0005] This utility model provides an optical device dispensing mechanism and dispensing device, the purpose of which is to solve the problem that the optical device dispensing mechanism needs to adjust the needle when changing the syringe in the prior art.

[0006] To achieve the above objectives, this utility model provides an optical device dispensing mechanism, including...

[0007] needle;

[0008] A syringe, the interior of which is used to contain the adhesive solution;

[0009] A connecting tube, wherein the syringe and the needle are connected via the connecting tube, the adhesive can reach the needle through the connecting tube, and the syringe and the connecting tube can be detachably connected; and

[0010] A hollow stepper motor is installed in conjunction with a connecting tube. When the hollow stepper motor operates, it causes the needle, syringe, and connecting tube to rotate.

[0011] In this design, the syringe and needle are connected via a connecting tube, which is detachable from the syringe. Therefore, when the adhesive needs to be changed, only the connecting tube needs to be disconnected from the syringe; the connection between the connecting tube and the needle remains unchanged. Thus, this design solves the problem in existing technologies where needle recalibration is required when changing the syringe.

[0012] Preferably, since the connecting tube and the syringe are detachably connected, to ensure a more stable connection between them, this solution also includes a connecting frame. The connecting frame is disposed at the connection point between the syringe and the connecting tube, and is connected to the connecting tube. The connecting frame has a receiving groove, into which the syringe can be accommodated. In this solution, the syringe can be accommodated inside the receiving groove of the connecting frame, while the connecting frame is fixedly connected to the connecting tube. Therefore, the connecting frame stabilizes the syringe and the connecting tube, resulting in greater stability.

[0013] Preferably, to detect the number of dispensing turns of the needle, this solution further includes a turn detection module. The turn detection module includes a detector and a connecting piece. The connecting piece is connected to the connecting tube, syringe, or needle, and the detector is positioned corresponding to the connecting piece. In this solution, the connecting piece is connected to the connecting tube; when the connecting tube rotates, the connecting piece rotates accordingly. As the connecting piece rotates, it is detected by the detector. The number of rotations of the connecting piece can then be detected by the detector.

[0014] Preferably, the connecting piece in this solution is fixedly connected to the connecting tube.

[0015] The detector described in this solution is a photoelectric sensor.

[0016] Preferably, since the dispensing position is located on the side of the optical device, to ensure the adhesive is dispensed precisely to the designated location, the nozzle of the needle in this design faces sideways. This design, by having the nozzle outlet facing sideways, allows for accurate dispensing of adhesive to the side of the optical device.

[0017] The needle described in this solution is L-shaped overall.

[0018] Preferably, to achieve dispensing around the optical device and to ensure the needle can move precisely to the dispensing position on the optical device, this solution also includes a moving module connected to the hollow stepper motor. The moving module drives the needle to move. This solution uses the moving module as the power source to move the needle, allowing it to dispense around the optical device and precisely reach the dispensing position.

[0019] Preferably, in order to enable the needle to move to the dispensing height, the moving module of this solution includes a lifter, which is used to move the needle up and down. In this solution, the lifter moves the needle up and down, allowing the needle to be precisely moved to the dispensing height, thereby achieving precise dispensing.

[0020] Preferably, to ensure the needle wraps around the optical device and moves precisely to the dispensing position, the moving module in this solution includes a transverse mover, which drives the needle to move laterally. This solution configures the transverse mover to drive the needle to move in a circle and precisely move the needle to the dispensing position.

[0021] Preferably, to identify the location of the optical device and the dispensing location, this solution further includes an image recognition module and a controller, wherein the image recognition module and the movement module are signal-connected to the controller. This solution uses the image recognition module to identify the location of the optical device and the dispensing location, and then feeds the location information back to the controller. The controller controls the movement module to move the needle precisely to the dispensing location for dispensing.

[0022] The second aspect of this utility model discloses an optical device dispensing apparatus, including the aforementioned optical device dispensing mechanism and optical device fixture, wherein the optical device fixture is used to place optical devices. The optical devices are placed on the optical device fixture, and then the optical device dispensing mechanism dispenses adhesive onto the optical devices on the optical device fixture.

[0023] The beneficial effects of this invention are as follows: In this design, the syringe and needle are connected by a connecting tube, and the connecting tube and syringe are detachable. Therefore, when the adhesive needs to be replaced, only the connecting tube needs to be separated from the syringe. The connection between the connecting tube and the needle remains unchanged, and the position of the needle does not change. Therefore, even if the syringe is replaced, it is not necessary to recalibrate the needle. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0031] Example 1

[0032] The basics are as follows: Figure 1 As shown, an optical device dispensing mechanism includes a syringe 1, a connecting tube 2, a needle 3, a hollow stepper motor 4, and a mounting bracket 5.

[0033] In this embodiment, the hollow stepper motor 4 is mounted on a mounting frame 5, which serves as the mounting base for the hollow stepper motor 4. The hollow stepper motor 4 can be connected to the mounting frame 5 by welding or by using fasteners. A syringe 1 and a needle 3 are respectively provided above and below the hollow stepper motor 4. The syringe 1 is specifically a cylindrical body that can hold adhesive. The needle 3 is an L-shaped needle with its outlet facing to the side. A connecting tube 2, which is a metal tube, is installed inside the hollow stepper motor 4. The upper end of the connecting tube 2 is connected to the syringe 1, and the lower end of the connecting tube 2 is connected to the needle 3. The syringe 1 and the needle 3 are connected through the connecting tube 2, and the adhesive contained inside the syringe 1 can be released through the connecting tube 2 to the needle 3, and finally released from the outlet of the needle 3 to the outside to complete the dispensing.

[0034] In this preferred embodiment, the syringe 1 and the connecting tube 2 are detachably connected, specifically by a plug-in connection. That is, the front end of the syringe 1 is inserted into the connecting tube 2, or the rear end of the connecting tube 2 is inserted into the front end of the syringe 1. When the syringe 1 needs to be replaced, it is disconnected from the connecting tube 2, allowing the syringe 1 to be replaced. The new syringe 1 contains new adhesive. During the replacement of the syringe 1, the needle 3 remains connected to the connecting tube 2, preventing misalignment of the needle 3 and eliminating the need for needle repositioning, thus facilitating use.

[0035] Since the syringe 1 and the connecting tube 2 are detachable, a connecting frame 6 is provided at the connection point of the syringe 1 and the connecting tube 2 to ensure a more stable connection. The connecting frame 6 is a rectangular frame, which can be made of metal or plastic. The connecting frame 6 has an internal receiving groove, which is a cylindrical tube. The size of the receiving groove is adapted to the size of the syringe 1, and it can be used to accommodate the syringe 1. The lower end of the connecting frame 6 is fixedly connected to the connecting tube 2 by welding or bonding. Therefore, in this embodiment, the connecting frame 6 serves as a support, ensuring the stability of the syringe 1 and the stable connection between the connecting tube 2 and the syringe 1, preventing the syringe 1 from detaching from the connecting tube 2.

[0036] In this embodiment, the needle 3 is an L-shaped needle. Therefore, when the hollow stepper motor 4 drives the connecting tube 2 to rotate, the syringe 1 and the needle 3 will also rotate accordingly. When the needle 3 rotates, the dispensing direction of the needle 3 changes, so that the outlet of the needle 3 can always face the side of the optical device, and the outlet of the needle 3 is aligned with the position where the adhesive needs to be dispensed.

[0037] Since the syringe 1 rotates when the hollow stepper motor 4 is working, to ensure the normal output of the adhesive solution inside the syringe 1 and to prevent problems such as tubing entanglement during rotation, this embodiment preferably uses pneumatic discharge of the adhesive solution from the syringe 1. During installation, an adapter 11 is installed on the top of the syringe 1, and the adapter 11 is connected to a rotary joint 12. The rotary joint 12 is then connected to an air tube, which in turn is connected to an air supply device. The air supply device can be an air pump or other existing air supply devices.

[0038] The dispensing process is described below: When dispensing is required, the air supply device operates. The air supply device outputs airflow to the air tube. The gas enters the syringe 1 through the rotary joint 12 and adapter 11, pushing the glue solution inside the syringe 1 outwards. Simultaneously, when the syringe 1 rotates, the air tube will not become entangled due to the rotary joint 12.

[0039] Example 2

[0040] This embodiment is an improvement on embodiment 1, such as... Figure 2 As shown, in this embodiment, a rotation count detection module 7 is provided to determine the number of dispensing revolutions. The rotation count detection module 7 detects the number of rotations of the needle 3. The rotation count detection module 7 includes a detector 72, a connecting piece 71, and a mounting plate. The mounting plate is located on top of the hollow stepper motor 4 and is connected to the hollow stepper motor 4 by welding or fasteners. The mounting plate serves as the mounting base for the detector 72. The detector 72 is preferably a photoelectric sensor, which is mounted on the top of the mounting plate by fasteners or adhesive. The connecting piece 71 can be connected to any one of the connecting tube 2, the needle 3, or the syringe 1, and more preferably, the connecting piece 71 is fixedly connected to the connecting tube 2. Specifically, the connecting tube 2 can be welded to the connecting piece 71. When the connecting tube 2 is driven to rotate by the hollow stepper motor 4, the connecting piece 71 also rotates. During the rotation of the connecting piece 71, it passes through the photoelectric sensor and is thus identified by the photoelectric sensor. The number of rotations of the connecting piece 71 is determined by the number of times the photoelectric sensor detects it.

[0041] It should be noted that in this embodiment, the photoelectric sensor is mounted on the mounting plate, which is then connected to the hollow stepper motor 4. However, in some other embodiments, the mounting plate can be located in other positions; for example, it can be mounted on the mounting bracket 5, and then the detector 72 is mounted on the mounting plate. Furthermore, while a photoelectric sensor is preferred as the detector 72 in this embodiment, other detectors 72 can be used in some other embodiments, such as a pressure sensor, which detects the pressure when the connecting piece 71 contacts the pressure sensor.

[0042] Example 3

[0043] This embodiment is an improvement on embodiment 1 or embodiment 2, such as... Figure 3 and Figure 4 As shown, in this embodiment, a moving module 8 is provided to enable the movement of the needle 3. The moving module 8 serves as the driving force for the movement of the needle 3.

[0044] The moving module 8 in this embodiment includes a lifter 81 and a transverse mover 82. The lifter 81 is preferably an electric slide, which is vertically arranged. The mounting frame 5 is directly connected to the slider in the electric slide with fasteners. When the electric slide is working, it drives a sliding lifting motion, thereby causing the mounting frame 5 and the needle 3, syringe 1, connecting tube 2, and hollow stepper motor 4 mounted on the mounting frame 5 to move up and down. When the lifter 81 drives the needle 3 to move up and down, the needle 3 moves closer to or further away from the optical device. The transverse mover 82 is specifically an XY motion module. The transverse mover 82 is fixedly connected to the lifter 81 and can drive the lifter 81 to move in the XY direction, thereby adjusting the horizontal position of the needle 3.

[0045] It should be noted that the moving module 8 in this embodiment is only one implementation of the moving module 8. In some other implementations, the moving module 8 can also be a robotic arm, which can drive the dispensing position of the needle 3 to change.

[0046] The following describes the working process of the moving module 8: When dispensing is required, the moving module 8 drives the needle 3 to precisely move to the dispensing position to achieve dispensing. Simultaneously, the moving module 8 drives the needle 3 to perform a circular motion, ensuring that dispensing is completed around the entire optical component. As the needle 3 performs this circular motion around the optical component, it is rotated by the hollow stepper motor 4, ensuring that the dispensing nozzle of the needle 3 is always directly facing the optical component.

[0047] To determine the position of the light-emitting device and ensure that the needle 3 accurately reaches the location where adhesive needs to be applied, this embodiment also includes an image recognition module 9 and a controller. The image recognition module 9 can be an image recognition camera, which is mounted on the mounting bracket 5 and is connected to the controller. The controller is also connected to the motion module 8. The controller can be an industrial computer or a PLC control module, or other existing controller technologies.

[0048] The following describes the cooperation process between the image recognition module 9 and the moving module 8: When dispensing is required, the moving module 8 moves, allowing the image recognition camera on the mounting bracket 5 to identify the position of the optical device and feed the position information back to the controller. The controller controls the moving module 8 to move precisely, ensuring that the dispensing nozzle of the needle 3 reaches the required dispensing position, thus completing the dispensing process.

[0049] Example 4

[0050] This embodiment provides a dispensing device, including the optical device dispensing mechanism of Embodiment 3 and the optical device fixture. The optical device fixture is elongated. The surface of the optical device fixture has several positioning grooves. The positioning grooves are generally rectangular, and the interior of the positioning grooves is used to accommodate the optical device, so that the optical device remains stable and avoids dispensing errors. The needle 3 in the optical device dispensing mechanism moves to the optical device position on the optical device fixture to complete the dispensing of the optical device.

[0051] Meanwhile, to ensure greater stability of the optical device on the fixture, this embodiment also includes a positioning channel on the side of the positioning groove. A spring is installed inside the positioning channel, and the spring engages with a top bead. The top bead is positioned at the opening of the positioning channel. When the optical device is inside the positioning groove, the top bead holds the device in place, making it more stable within the groove.

[0052] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
