[0003] For existing optical communication industry transceiver devices, interface components such as TO, BOSA, and ROSA usually use manual dispensing. For example, manual dispensing requires workers to hold the dispensing syringe in their right hand and fill the gap between the laser receiving end with glue along a circle. Since the amount of glue is difficult to control, the pre-coupled receiving end product is easily offset when the handheld dispensing needle touches the product, and the glue amount standard is extremely high, and the uneven glue filling is difficult to control.

[0062] See also Figure 1 and Figure 2The present embodiment provides a glue dispensing mechanism for an optical device, including a glue dispensing syringe 110, a curved needle head 120 and an R-axis rotating component 130, wherein the curved needle head 120 is connected to the glue dispensing syringe 110, and the R-axis rotating component 130 is drivingly connected to the glue dispensing syringe 110, wherein the R-axis rotating component 130 includes: a rotating substrate 140, a first bearing 150 and a driving component 160, the rotating substrate 140 is rotatably connected to the glue dispensing syringe 110, the outer wall of the first bearing 150 is embedded in the rotating substrate 140, and the first bearing 150 is sleeved on the glue dispensing syringe 110, the driving component 160 is disposed on the rotating substrate 140, and the driving component 160 is drivingly connected to the glue dispensing syringe 110 to realize the rotational connection between the glue dispensing syringe 110 and the rotating substrate 140.

[0063] In this embodiment, the glue dispensing syringe 110 is rotatably connected to the rotating substrate 140 via the first bearing 150, and the driving component 160 is drivingly connected to the glue dispensing syringe 110. The driving component 160 can drive the glue dispensing syringe 110 to rotate along the rotating substrate 140, so that the curved needle head 120 can rotate around the product to be dispensed, thereby realizing glue dispensing in the side groove of the product to be dispensed.

[0064] It can be seen that the present application realizes the rotation of the curved needle head 120 through the driving component 160 and the first bearing 150, which can realize the dispensing of glue in the groove on the side of the workpiece, and can improve the dispensing efficiency and dispensing accuracy. The dispensing syringe 110 is rotatably connected to the rotating base plate 140 through the first bearing 150, and the structure is simple and compact, which can save space.

[0065] Specifically, see Figure 3 The driving component 160 includes: a first rotating motor 161, a first transmission shaft 162, a driving pulley 163, a driven pulley 164 and a synchronous belt 165. The first rotating motor 161 is arranged on the rotating substrate 140, the first transmission shaft 162 is connected to the first rotating motor 161, the driving pulley 163 is connected to the first transmission shaft 162, the driven pulley 164 is matched with the driving pulley 163, and the driven pulley 164 is sleeved on the dispensing syringe 110, and the synchronous belt 165 is wound around the driving pulley 163 and the driven pulley 164.

[0066] In this embodiment, the first rotating motor 161 can drive the first transmission shaft 162 to rotate, the first transmission shaft 162 drives the driving pulley 163 to rotate, the driving pulley 163 can drive the driven pulley 164 through the synchronous belt 165, and then drive the dispensing syringe 110 to rotate.

[0067] It can be seen that the first rotating motor 161 can drive the synchronous belt 165 to drive the curved needle head 120 to rotate, with precise transmission ratio, no slippage, constant speed ratio, precise transmission, smooth transmission, high transmission efficiency, compact structure, and low tension, thereby ensuring the stable operation of the curved needle head 120.

[0068] Specifically, see Figure 4 The driving component 160 also includes: a connecting ring 170 , which is sleeved on the dispensing syringe 110 , and the connecting ring 170 is embedded in the driven pulley 164 .

[0069] In this embodiment, the connecting collar 170 is used to connect with the glue syringe 110, so that the glue syringe 110 can be easily connected with the driven pulley 164. For example, during installation, the connecting collar 170 can be sleeved on the glue syringe 110, and then the driven pulley 164 is sleeved on the connecting collar 170. On the one hand, the connecting collar 170 can increase the friction with the glue syringe 110 to prevent the glue syringe 110 from slipping. On the other hand, the connecting collar 170 can facilitate the disassembly of the glue syringe 110 and the maintenance of the glue syringe 110.

[0070] It can be seen that the connecting ring 170 is connected to the driven pulley 164 and the glue dispensing syringe 110. The connecting ring 170 can increase the installation space for the driven pulley 164 to facilitate the assembly of the driven pulley 164 and the glue dispensing syringe 110, and can facilitate the quick disassembly and assembly of the glue dispensing syringe 110.

[0071] Specifically, see Figure 5 The connecting ring 170 includes: a sleeve body 171, a pulley connecting portion 172, a sleeve flange 173, and a bearing connecting portion 174. The sleeve body 171 is sleeved on the glue syringe 110, and the pulley connecting portion 172 is arranged on the sleeve body 171. The pulley connecting portion 172 is used for transmission connection with the driven pulley 164. The sleeve flange 173 extends outward from the pulley connecting portion 172, and the sleeve flange 173 is used to abut against the driven pulley 164. The bearing connecting portion 174 is located on the side of the sleeve flange 173 away from the pulley connecting portion 172, and the bearing connecting portion 174 is embedded in the first bearing 150 to connect the glue syringe 110 and the first bearing 150.

[0072] In this embodiment, the upper end of the connecting collar 170 is connected to the driven pulley 164 through the pulley connecting portion 172, and the lower end of the connecting collar 170 is connected to the first bearing 150 through the bearing connecting portion 174, that is, the connecting collar 170 is sleeved on the outer wall of the dispensing syringe 110, and the first bearing 150 is sleeved on the outer wall of the connecting collar 170. Since the dispensing syringe 110 is usually made of plastic, and the dispensing syringe 110 needs to be at a constant temperature during the dispensing process, the dispensing syringe 110 may be deformed by heat, which may easily cause the dispensing syringe 110 and the driven pulley 164 and the first bearing 150 to have connection failure. Therefore, the connecting collar 170 can ensure the stable connection between the dispensing syringe 110 and the driven pulley 164 and the first bearing 150, and ensure the stable rotation of the curved needle head 120.

[0073] For example, the sleeve flange 173 may be provided with a keyway 175 , and the sleeve flange 173 is engaged and connected with the driven pulley 164 through the keyway 175 , which can ensure that the connecting ring 170 is effectively connected with the driven pulley 164 .

[0074] It can be seen that the sleeve flange 173 can provide support for the driven pulley 164 to provide an installation space for the driven pulley 164. The pulley connecting portion 172 is located between the driven pulley 164 and the glue syringe 110, which can strengthen the connection between the driven pulley 164 and the glue syringe 110 and ensure the stability of the transmission. The bearing connecting portion 174 is located between the first bearing 150 and the glue syringe 110 to strengthen the connection between the first bearing 150 and the glue syringe 110.

[0075] Specifically, see Figure 4 The optical device dispensing mechanism 100 also includes: a rotating platform 180, the rotating platform 180 includes a rotating base plate 181 and a second bearing 182, the rotating base plate 181 is located on the side of the dispensing syringe 110 close to the curved needle head 120, and the rotating base plate 140 is located on the side of the dispensing syringe 110 away from the curved needle head 120; the outer wall of the second bearing 182 is embedded in the rotating base plate 181, and the second bearing 182 is connected to the dispensing syringe 110, and the second bearing 182 is used to be rotatably connected to the dispensing syringe 110.

[0076] In this embodiment, it can be understood that the rotating base plate 140 is located at the upper end of the dispensing syringe 110, and the rotating bottom plate 181 is located at the lower end of the dispensing syringe 110. The rotating base plate 140 is rotatably connected to the dispensing syringe 110 through the first bearing 150, and the rotating bottom plate 181 is rotatably connected to the dispensing syringe 110 through the second bearing 182. The up and down arrangement can ensure the rotation stability of the dispensing syringe 110 and prevent the dispensing syringe 110 from deflecting during the dispensing process.

[0077] It can be seen that the rotating platform 180 includes a rotating base plate 181 and a second bearing 182 . The rotating base plate 181 is rotatably connected to the glue syringe 110 via the second bearing 182 to coordinate with the rotation of the glue syringe 110 and the rotating base plate 140 to ensure the smooth rotation of the glue syringe 110 .

[0078] Optionally, the second bearing 182 may include: a plane bearing, which is embedded in the rotating base plate 181 and abuts against the bottom of the dispensing syringe 110 .

[0079] For example, the rotating base plate 181 is rotatably connected to the bottom of the glue syringe 110 through a plane bearing. As mentioned above, the rotating base plate 140 is rotatably connected to the glue syringe 110 through the first bearing 150. The combination of the first bearing 150 and the plane bearing can further ensure the smooth rotation of the glue syringe.

[0080] It can be seen that the plane bearing is used to support the dispensing syringe 110 and can withstand the axial load of the dispensing syringe 110, so that the dispensing syringe 110 can rotate more steadily and smoothly. The design is compact and can prevent the dispensing syringe 110 from getting stuck during rotation.

[0081] Optionally, the bending angle of the curved needle 120 ranges from 90° to 150°.

[0082] For example, the bending angle of the curved needle 120 ranges from 90° to 150°, so there is no need to adjust the position and angle of the glue dispensing needle to dispense glue on the inner wall of the product to be dispensed, which saves operating space.

[0083] For example, the bending angle of the curved needle head 120 is 135°. During the dispensing process, the curved needle head 120 can dispense glue to the side wall of the product to be dispensed without adjusting the position and angle of the dispensing needle head. The operation is simple and the dispensing efficiency is high.

[0084] It can be seen that the bending angle range of the curved needle head 120 is 90°-150°, which can realize glue dispensing in the groove on the side of the workpiece. The curved needle head 120 can rotate around the workpiece to apply glue, and the glue dispensing efficiency is high.

[0085] Specifically, see Figure 4 The optical device dispensing mechanism 100 also includes: a syringe constant temperature module 190, which is located between the rotating bottom plate 181 and the rotating base plate 140, and the syringe constant temperature module 190 is wrapped around the dispensing syringe 110, and the syringe constant temperature module 190 is used to heat and keep the dispensing syringe 110 warm.

[0086] In this embodiment, the syringe constant temperature module 190 is located between the rotating bottom plate 181 and the rotating base plate 140, and the syringe constant temperature module 190 is wrapped around the glue dispensing syringe 110. During the glue dispensing process, the syringe constant temperature module 190 can heat and keep the glue dispensing syringe 110 warm, so that the glue dispensing syringe 110 has a constant temperature function, which can be adjusted from 0 to 100°C, and can maintain a precise constant temperature to ensure the fluidity of the glue.

[0087] It can be seen that the syringe constant temperature module 190 can heat the glue in the glue dispensing syringe 110, so that the glue maintains a constant temperature and keeps the glue in a good flow state, thereby ensuring the stability and quality of glue dispensing.

[0088] Based on the optical device dispensing mechanism 100 in the above embodiment, the present application provides a dispensing device, wherein the dispensing device includes the optical device dispensing mechanism 100 in the above embodiment. Thus, the dispensing device can have all the features and effects of the above optical device dispensing mechanism 100, which will not be repeated here.

[0090] In this embodiment, the visual scanning module 600 can scan the product to be glued on the workpiece fixture 500 to generate a glue dispensing path, and then the optical device glue dispensing mechanism 100 realizes automatic glue dispensing by cooperating with the X-axis left and right moving mechanism 200, the Z-axis up and down moving mechanism 300, the R-axis rotating component and the Y-axis forward and backward moving mechanism 400. The glue dispensing accuracy is high and the glue dispensing work is more flexible. The Z-axis up and down moving mechanism 300 can monitor the height difference of the product in real time through the laser height measurement module 700 and automatically adjust it to guide the curved needle head 120 to perform contactless product follow-up glue dispensing, thereby improving the glue dispensing efficiency and glue dispensing quality.
