Description

Technical Field

[0001] This utility model relates to the field of optical device coupling technology, specifically to a glue removal device and glue injection assembly for cleaning the glue outlet. 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 communication modules and optical components, lenses need to be mounted on a PCB board. During assembly, a dispensing device is used to release adhesive onto the coupling points on the PCB board, and the lens is then fixed in place by the adhesive. However, in practice, it has been found that during each dispensing operation, some adhesive remains at the dispensing nozzle. This residual adhesive is easily released into the bonding area during subsequent dispensing, leading to excessive adhesive and affecting the lens's coupling performance. Utility Model Content

[0004] The first aspect of this utility model aims to solve the aforementioned technical problems by providing a glue removal device for cleaning the glue outlet. This device cleans the glue outlet after extrusion through a glue removal mechanism, preventing glue residue at the outlet from causing excessive glue in the next dispensing cycle. The main concept is as follows:

[0005] A glue removal device for cleaning glue outlets includes a cleaning mechanism acting on the glue outlet. The cleaning mechanism includes a movable part and a glue removal part. The movable part includes a driving component and a telescopic component, the telescopic component connecting to the glue removal part. The glue removal part includes a mounting plate and a cleaning head, the cleaning head being disposed on the mounting plate. The movable part drives the cleaning head of the glue removal part to act on the glue outlet. This solution, by setting up a cleaning mechanism, ensures that after glue is extruded from the outlet, the movable part causes the glue removal part to act on the outlet, enabling the movable part to drive the glue removal part to complete a wiping action at the outlet, thus cleaning the glue outlet and preventing residual glue from being released into the adhesion area during the next dispensing, leading to excessive glue.

[0006] Preferably, the driving component is a pneumatic cylinder or a hydraulic cylinder.

[0007] Preferably, the cleaning head includes a sponge pad, a brush, or a cloth.

[0008] Preferably, the movement direction of the driving member is consistent with the output direction of the glue outlet, and the driving member controls the telescopic member in the vertical direction. The driving member provides vertical movement to the glue removal section, so that the glue removal section acts on the vertically opening glue outlet.

[0009] Preferably, the cleaning mechanism further includes a horizontal displacement stage, which provides multi-degree-of-freedom adjustment for the movable part. By adjusting the projection position of the adhesive removal part in the vertical direction using the horizontal displacement stage, the adhesive removal part can be vertically aligned with the adhesive outlet.

[0010] The second aspect of this utility model discloses a glue injection assembly, including the aforementioned glue removal device for cleaning the glue outlet, and also including a glue injection mechanism. The glue injection mechanism includes a glue injector and an output tube, the output position of which is the glue outlet, and the glue outlet and the cleaning mechanism are arranged opposite to each other.

[0011] The second aspect of this invention aims to solve the technical problem of excessive glue overflow from the dispensing port, preventing precise glue dispensing. Furthermore, the dispensing port is positioned upwards. This solution, by setting the dispensing port of the glue dispenser upwards, ensures that the glue in the output tube is subject to gravity, preventing overflow without pressure. Under the combined effect of gravity and the outward pressure of the glue dispenser, the flow rate is relatively stable and easy to control, allowing operators to more precisely control the amount of glue dispensed.

[0012] Preferably, the dispensing mechanism further includes a support frame, with the dispensing device mounted above the support frame. The support frame has a horizontally oriented positioning groove, which provides positioning support for the dispensing device and the output tube. The horizontally oriented positioning groove allows the dispensing device to be placed horizontally within the groove, resulting in a more uniform distribution of the adhesive within the device under gravity. Furthermore, the flow of the adhesive during the dispensing process is more stable, facilitating precise control of the dispensing volume and speed.

[0013] Preferably, the support frame is equipped with fasteners to lock the dispensing device within the positioning groove. The fasteners ensure stable installation of the dispensing device and prevent it from tipping over due to pressure when the cleaning mechanism acts on the dispensing nozzle.

[0014] Preferably, the device further includes an identification component, which comprises a vision scanner and a controller. The vision scanner is connected to the controller, and the controller is connected to the drive unit. The vision scanner is a camera, video camera, or scanner. The vision scanner is mounted on a support frame. The vision scanner senses whether the adhesive application to the lens is complete by sensing the output tube. By sending the identified information to the controller, the controller activates the drive unit, which then drives the adhesive removal section to clean the adhesive outlet. The vision scanner determines whether the workpiece being coated at the adhesive application mechanism has been removed. If removed, the cleaning mechanism is activated to clean the adhesive outlet. The support frame is a fixed structure, and mounting the vision scanner on the support frame ensures its stable operation.

[0015] The beneficial effects of this utility model are as follows: by setting up a cleaning mechanism, after the glue dispensing nozzle is extruded, the movable part causes the glue removal part to act on the glue dispensing nozzle, so that the movable part drives the glue removal part to complete the wiping action at the glue dispensing nozzle, thereby cleaning the glue dispensing nozzle and avoiding the problem of residual glue being released into the adhesion position during the next glue dispensing, which would lead to excessive glue.

Detailed Implementation

[0019] 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.

[0020] 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.

[0021] Example 1

[0022] like Figures 1-2 As shown, this embodiment provides a glue removal device for cleaning the glue outlet 41, including a cleaning mechanism acting on the glue outlet 41. The cleaning mechanism includes a movable part 2 and a glue removal part 3. The movable part 2 includes a driving member 21 and a telescopic member 22, which is connected to the glue removal part 3. The glue removal part 3 includes a mounting plate 31 and a cleaning head 32, which is disposed on the mounting plate 31. The movable part 2 drives the cleaning head 32 of the glue removal part 3 to act on the glue outlet 41.

[0023] In this embodiment, a cleaning mechanism is provided so that after the glue outlet 41 of the glue dispenser 1 is extruded, the glue removal part 3 is activated by the movable part 2 to act on the glue outlet 41, thereby cleaning the glue outlet 41.

[0024] like Figures 1-2 As shown, the driving component 21 can be a cylinder or a hydraulic cylinder; the cleaning head 32 can be a sponge pad, a brush, or a wiping cloth.

[0025] After the glue applicator 1 completes one application of glue, the cleaning mechanism starts and drives the telescopic component 22 to move via the drive component 21. This causes the glue removal part 3 connected to the telescopic component 22 to act at the glue outlet 41. The cleaning head 32 of the glue removal part 3 comes into contact with the glue outlet 41 and absorbs the glue residue at the glue outlet 41.

[0026] Example 2

[0027] like Figures 1-2 As shown, the cleaning mechanism of this embodiment also includes a horizontal displacement stage 6, which provides multi-degree-of-freedom adjustment for the movable part 2. The driving member 21 provides vertical movement to the adhesive removal part 3, so that the adhesive removal part 3 acts on the vertically opening adhesive outlet 41. The horizontal displacement stage 6 adjusts the projection position of the adhesive removal part 3 in the vertical direction, so that the adhesive removal part 3 can be vertically aligned with the adhesive outlet 41.

[0028] like Figure 2As shown, since the glue removal port of the glue dispenser 1 is vertically set, the movable part 2 can move vertically. In this embodiment, in order to enable the cleaning mechanism to move in multiple directions, the movable part 2 is mounted on the horizontal displacement stage 6. The horizontal displacement stage 6 includes an X-axis displacement stage and a Y-axis displacement stage, which can adjust the horizontal position arbitrarily within a certain range. When the cleaning mechanism is not working, the glue removal part 3 can be offset from above the glue outlet 41 by the horizontal displacement stage 6, so as to reserve a working position for the lens held by the lens transfer structure to perform the glue application process, and avoid interference between the lens transfer structure and the lens and the cleaning mechanism. The vertically moving movable part 2 and the horizontal displacement stage 6 enable the cleaning mechanism to move in the XYZ three-axis directions.

[0029] Example 3

[0030] like Figures 1-2 As shown, this embodiment provides a glue injection assembly, which includes a glue removal device and a glue injection mechanism as described in Embodiment 1 or Embodiment 2. The glue injection mechanism is used to inject glue, while the glue removal device cleans after glue injection. The glue injection mechanism includes a glue injector 1 and an output pipe 4. The output position of the output pipe 4 is a glue outlet 41, and the glue outlet (41) and the cleaning mechanism are arranged opposite to each other.

[0031] The output direction of the glue outlet 41 is vertically upward. By setting the glue outlet 41 of the glue dispenser 1 vertically upward, the glue in the output tube 4 is recycled back into the interior under the action of gravity after it is squeezed out, thus preventing the glue in the output tube 4 from overflowing.

[0032] The drive component 21 moves in the same direction as the output direction of the glue outlet 41, and the drive component 21 controls the telescopic component 22 in the vertical direction. Since the glue outlet 41 is vertically opened, the glue removal part 3 is positioned above the glue outlet 41 and also moves in the vertical direction, enabling the cleaning mechanism to quickly clean the glue outlet 41.

[0033] The dispensing mechanism also includes a support frame 5, on which the dispensing device 1 is mounted. The support frame 5 has a positioning groove 51 in the horizontal direction, which provides positioning support for the dispensing device 1 and the output tube 4. The support frame 5 is equipped with fasteners 52, which are used to lock the dispensing device 1 in the positioning groove 51.

[0034] The support frame 5 has a positioning groove 51 in the horizontal direction, so that the glue injector 1 can be placed horizontally in the positioning groove 51. The glue liquid in the glue injector 1 is more evenly affected by gravity, and the flow of glue liquid during the extrusion and injection process of the glue injector 1 is also more stable, which is conducive to precise control of the glue injection amount and injection speed.

[0035] like Figure 1As shown, the positioning groove 51 in this embodiment includes a first positioning groove 51 for positioning the cylinder of the dispensing device 1 and a second positioning groove 51 for positioning the output tube 4. The first positioning groove 51 and the second positioning groove 51 are adapted to the outer diameter of the cylinder and the output tube 4. The output tube 4 in this embodiment adopts an L-shaped structure, and the output tube 4 includes a horizontal section and a vertical section. One end of the horizontal section is connected to the dispensing tube, and the other end of the horizontal section is connected to the vertical section.

[0036] The support frame 5 uses an L-shaped support block for positioning the output pipe 4, and a second positioning groove 51 adapted to the output pipe 4 is provided on the support block.

[0037] Example 4

[0038] like Figures 1-2 As shown, this embodiment also includes an identification component, which includes a vision scanner 7 and a controller. The vision scanner 7 is connected to the controller, and the controller is connected to the drive unit 21. The vision scanner 7 senses whether the adhesive application on the lens by the identification output tube 4 is complete. By sending the identified information to the controller, the controller activates the drive unit 21, causing the drive unit 21 to drive the adhesive removal section 3 to clean the adhesive outlet 41.

[0039] The vision scanner 7 uses a camera, video camera, or scanner, and the controller uses components such as a microcontroller or PLC, which can receive signals from the vision scanner 7. The vision scanner 7 is mounted on the support frame 5. The vision scanner 7 determines whether the workpiece being coated at the glue dispensing mechanism has been removed. If it has been removed, it drives the cleaning mechanism to clean the glue outlet 41. The support frame 5 is a fixed structure, and mounting the vision scanner 7 on the support frame 5 ensures its stable operation.
