Description

Technical Field

[0001] This utility model relates to the field of optical device coupling technology, specifically to a glue injection device and coupling system. Background Technology

[0002] Optical communication packaging technology is the process of assembling and connecting optoelectronic devices, optical components, and other components with optical communication modules to achieve their specific functions and ensure long-term stable operation. Coupling, as a key step, mainly involves high-precision optical alignment, connection fixation, and optical signal quality control technologies and operations to ensure that optical signals can be transmitted efficiently and with low loss between different components, meeting the stringent requirements of optical communication systems for signal transmission quality and stability.

[0003] When coupling optical components to a PCB board, adhesive is used to bond and fix the optical components to the coupling points on the PCB board. However, existing adhesive dispensing devices inject adhesive into the coupling points on the PCB board, which is often placed horizontally upwards. Therefore, the dispensing device needs to inject the adhesive from top to bottom into the coupling points on the PCB board. This method has revealed new problems in practice. Mainly, because the dispensing device releases the adhesive from top to bottom, excess adhesive often overflows due to gravity, leading to an excessive amount of adhesive at the coupling points on the PCB board, ultimately affecting the coupling effect of the optical components. Utility Model Content

[0004] The first problem this invention aims to solve is that the amount of adhesive dispensed by the adhesive dispensing device in the prior art is difficult to control, which affects the coupling effect.

[0005] To solve the aforementioned technical problems, the first aspect of this utility model provides a glue dispensing device that improves the accuracy of glue dispensing by upwardly positioning the outlet of the glue dispensing tube so that the glue liquid is output against gravity. The main concept is as follows:

[0006] A glue dispensing device includes a glue dispenser and a glue outlet tube disposed at the outlet of the glue dispenser. The glue dispenser contains glue liquid, and the glue outlet tube includes an outlet section with the outlet facing upwards. This design sets the outlet of the glue outlet tube vertically upwards. The glue liquid in the outlet section of the glue outlet tube is subject to gravity, preventing it from overflowing without pressure. Under the combined action of gravity and the outward pressure of the glue dispenser, the flow rate of the glue is relatively stable and easy to control, allowing operators to more precisely control the amount of glue dispensed.

[0007] Preferably, the dispensing device is equipped with an electrically controlled extruder, which is used to stably control the amount of adhesive dispensed from the dispensing device. The dispensing device uses electrical control for extrusion, resulting in a more uniform and stable dispensing volume.

[0008] Preferably, the mounting bracket includes a first positioning groove for positioning the dispensing device. To ensure stable support for the dispensing device, a first positioning groove is provided on the mounting bracket to accommodate it.

[0009] Preferably, the first positioning groove is opened horizontally along the mounting frame, and the dispensing device is horizontally installed in the first positioning groove. The horizontally set first positioning groove allows the dispensing device to also be placed horizontally, making the gravitational influence on the adhesive more uniform within the dispensing device, and the flow of adhesive during the dispensing process is also more stable, which is beneficial for accurately controlling the dispensing volume and dispensing speed.

[0010] The second aspect of this utility model aims to solve the technical problem of unstable installation of the dispensing device on the first mounting bracket. Preferably, the first mounting bracket includes a locking mechanism, which includes a clamping part and a locking part constructed in the first positioning groove. The clamping part is movably connected to the first mounting bracket, and the clamping part and the locking part are detachably connected. This solution applies the clamping part to the dispensing device installed in the first positioning groove, thereby tightly pressing and constraining the dispensing device in the first positioning groove. By locking the clamping part in the clamped state, the dispensing device is locked in the first positioning groove.

[0011] Preferably, the mounting bracket further includes a second positioning groove, which provides support and positioning for the dispensing tube. Since the dispensing tube extends outward relative to the output port of the dispensing device, it is prone to wobbling. By providing the second positioning groove to position and support the dispensing tube, the dispensing tube can be made more stable when extruding glue.

[0012] Preferably, the device also includes an identification component, which comprises a sensor and a controller. The sensor is used to identify whether a workpiece is present at the outlet of the dispensing tube, and the controller is electrically connected to the electronically controlled extruder of the dispensing device. This solution configures the identification component so that when the transfer mechanism moves the lens above the dispensing tube, the sensor sends the identified information to the controller, which then drives the electronically controlled extruder to extrude the dispensing tube.

[0013] A second aspect of this invention provides a coupling system, including the aforementioned glue-dispensing device.

[0014] Preferably, it also includes a support mechanism for placing the PCB board and a transfer mechanism for moving the lens, wherein the lens and the PCB board are connected by adhesive extruded from an adhesive dispensing device.

[0015] The beneficial effects of this utility model are as follows:

[0016] By setting the outlet of the dispensing tube vertically upwards, the adhesive inside the output section of the tube is subject to gravity. The adhesive must overcome gravity to be discharged outwards. This design helps prevent the adhesive from overflowing due to gravity when there is no pressure. Furthermore, because the adhesive is discharged outwards against gravity, compared to existing technologies, the adhesive will not flow to the outlet under the influence of gravity. The flow rate of the adhesive is relatively stable and easy to control, allowing operators to more precisely control the amount of adhesive extruded. Attached Figure Description

Detailed Implementation

[0020] 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 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.

[0021] 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.

[0022] Example 1

[0023] like Figs. 1-2 As shown, this embodiment provides a dispensing device, including a dispensing nozzle 1 and a dispensing tube 2 disposed at the output port of the dispensing nozzle 1. The dispensing nozzle 1 is used to contain adhesive liquid, which can be a photocurable adhesive used in the prior art. The dispensing tube 2 includes an output section 21, and the outlet direction of the output section 21 is upward. More preferably, it is vertically upward.

[0024] This design sets the outlet of the dispensing tube 2 vertically upward. The adhesive in the output section of the dispensing tube 2 is subject to gravity, preventing the adhesive from overflowing when there is no pressure. Under the combined action of gravity and the outward pressure of the dispensing device 1, the flow rate of the adhesive is relatively stable and easy to control, allowing operators to more accurately control the amount of adhesive extruded.

[0025] The dispensing device 1 is equipped with an electrically controlled extruder 3, which is used to stably control the dispensing volume of the dispensing device 1. The dispensing device 1 performs extrusion in an electrically controlled manner, making the dispensing volume more uniform and stable.

[0026] The electrically controlled extruder 3 includes a motor, a transmission component, and an extrusion head. The motor converts electrical energy into mechanical energy, and the transmission component then converts the rotational motion into the linear motion of the extruder, thereby controlling the extrusion of the adhesive liquid inside the dispensing unit. The transmission component can be a lead screw drive with a nut mounted on it. The rotational motion of the lead screw is converted into linear motion by the nut, pushing a screw connected to the nut forward within the dispensing unit's barrel. Simultaneously, the extrusion head connected to the screw's output end propels the adhesive liquid forward. The extrusion head can be a rubber piston head, which moves inside the dispensing unit to extrude the adhesive liquid outward.

[0027] In addition, in some other embodiments, the glue dispenser 1 can also use a structure capable of linear motion, such as a manual extruder, a pneumatic extruder, or a hydraulic extruder, to dispense glue.

[0028] like Fig. 2 As shown, the mounting frame 4 in this embodiment includes a first positioning groove 41, which is used to position the dispensing device 1. To ensure stable support for the dispensing device 1, a first positioning groove 41 is provided on the mounting frame 4 to accommodate it. The first positioning groove 41 is horizontally positioned along the mounting frame 4, and the dispensing device 1 is horizontally installed within it. The horizontally positioned first positioning groove 41 allows the dispensing device 1 to also be placed horizontally, resulting in a more uniform gravitational influence on the adhesive within the dispensing device 1. Furthermore, the flow of the adhesive during the dispensing process is more stable, facilitating precise control of the dispensing volume and speed.

[0029] In this embodiment, the first mounting bracket 4 includes a locking mechanism 5. The locking mechanism 5 includes a clamping part 51 and a locking part 52 constructed in the first positioning groove 41. The clamping part 51 is movably connected to the first mounting bracket 4, and the clamping part 51 and the locking part 52 are detachably connected. This solution applies the clamping part 51 to the dispensing device 1 installed in the first positioning groove 41, so that the dispensing device 1 is tightly pressed and constrained in the first positioning groove 41. By locking the clamping part 51 in the clamped state with the locking part 52, the dispensing device 1 is locked in the first positioning groove 41.

[0030] like Fig. 2 As shown, the mounting bracket 4 also includes a second positioning groove 42, which is used to provide support and positioning for the dispensing tube 2. Since the dispensing tube 2 extends outward relative to the output port of the dispensing device 1, it is prone to shaking. By setting the second positioning groove 42 to position and support the dispensing tube 2, the dispensing tube 2 can be made more stable when dispensing glue.

[0031] like Figs. 1-2 As shown, the output tube in this embodiment adopts an L-shaped structure. The dispensing tube 2 also includes a connecting section. One end of the connecting section is connected to the dispensing tube, and the other end of the connecting section is connected to the output section 21. The mounting bracket 4 uses an L-shaped support block for positioning the dispensing tube 2, and a second positioning groove 42 adapted to the dispensing tube 2 is provided on the support block.

[0032] Example 2

[0033] This embodiment is an improvement on embodiment 1. This embodiment also includes an identification component, which includes a sensor and a controller. The sensor is used to identify whether there is a workpiece at the outlet position of the tube 2, and the controller is electrically connected to the electronically controlled extruder 3 of the dispensing machine 1.

[0034] The identification component is set up so that when the transfer mechanism moves the lens above the dispensing tube 2, the sensor sends the identification information to the controller, which then drives the electronically controlled extruder 3 to expel the glue from the dispensing tube.

[0035] The sensor in this embodiment is an image recognition sensor, specifically an RGB camera, a depth camera, or an infrared / ultraviolet sensor. The controller in this embodiment uses existing control modules such as microcontrollers and PLCs, which can receive signals from the sensors to monitor relevant parameters during the dispensing process. The controller controls the movement of the electronically controlled extruder according to preset programs and parameters to achieve automated dispensing control.

[0036] Example 3

[0037] This embodiment provides a coupling system, including the glue injection device of Embodiment 1 or Embodiment 2; it also includes a support mechanism for placing a PCB board and a transfer mechanism for moving a lens, wherein the lens and the PCB board are connected by glue extruded from the glue injection device.

[0038] The PCB board support mechanism in this embodiment can be a support mechanism for fixing the PCB board in the prior art. Similarly, the transfer mechanism can be a transfer mechanism for moving the lens in the prior art. The purpose of the transfer mechanism is to move the lens to the mating position with the glue-dispensing device for glue dispensing, and then, after the lens has been glued, to install the lens with glue onto the coupling position on the PCB board.

[0039] 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.
