Detailed implementation manners

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0029] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides an AOC coupling device 100, including: a mounting table 110, and a first positioning table 120, a second positioning table 130 and a first linear drive module 140 arranged on the mounting table 110. The first positioning table 120 is used for placing a cable connector containing an optical fiber coupler, the second positioning table 130 is used for placing an optical module, and the first linear drive module 140 is respectively connected with a second linear drive module 150 and a third linear drive module 160. A clamping assembly 170 and a UV lamp module 180 are arranged on the second linear drive module 150, and a dispensing assembly 162 and a vision module 164 are arranged on the third linear drive module 160. An optical power meter 112 and a light source 114 corresponding to the cable connector are also arranged on the mounting table 110; the clamping assembly 170 is used for clamping the cable connector so that the cable connector is coupled with the optical module; the light source 114 is used for emitting laser to the cable connector, the optical power meter 112 is used for receiving the optical signal returned by the cable connector, the dispensing assembly 162 is used for dispensing under the detection of the vision module 164 to bond the coupled cable connector and optical module, and the UV lamp module 180 is used for curing after dispensing.

[0030] Specifically, when the AOC coupling device 100 provided in the embodiments of the present application is in use, it is necessary to first place the cable connector containing the fiber optic coupler on the first positioning table 120, and then the first linear drive module 140 operates to synchronously move the second linear drive module 150 and the third linear drive module 160 to the first positioning table 120 to clamp the cable connector through the clamping assembly 170. After the clamping assembly 170 clamps the cable connector, the first linear drive module 140 operates again to drive the second linear drive module 150 and the third linear drive module 160 to synchronously move to the second positioning table 130, so as to facilitate the second linear drive module 150 to drive the cable connector to be coupled and docked with the optical module. During the coupling process, the light source 114 emits laser light to the cable connector, and after the optoelectronic conversion of the optical module, signal light is emitted to the cable connector again. At this time, the coupling effect is judged according to the optical signal situation detected by the optical power meter 112. After the coupling is completed, the third linear drive module 160 operates to apply glue to fix the coupling point. In order to ensure the accuracy of glue application, the vision module 164 can be used for detection to ensure the reliability of glue application. After glue application, in order to make the glue solidify quickly, the UV lamp module 180 can be used for irradiation. By adopting the above method, automatic coupling can be realized, and the coupling result can be directly obtained through the optical power meter 112, which is beneficial to improving the coupling efficiency.

[0031] It should be noted that the driving directions of the second linear drive module 150 and the third linear drive module 160 are the same, and the driving direction of the second linear drive module 150 is perpendicular to the driving direction of the first linear drive module 140 to ensure that the clamping assembly 170 can move in space after clamping the cable connector to realize the required coupling process. In addition, the optical power meter 112 and the light source 114 can be directly arranged on the mounting table 110, or can be arranged at a position that does not affect other components through a frame body. The embodiments of the present application do not make specific restrictions on this.

[0032] As Figure 2 and Figure 3 shown, the first linear drive module 140 includes a first vertical frame 142 arranged on the mounting table 110, and a linear drive assembly 144 and a slide rail 146 arranged on the first vertical frame 142. The extending direction of the slide rail 146 is the same as the transmission direction of the linear drive assembly 144. The second linear drive module 150 and the third linear drive module 160 are connected to the linear drive assembly 144 through a mounting plate 148, and the mounting plate 148 is slidably connected to the slide rail 146.

[0033] Specifically, by means of the first vertical frame 142 provided on the installation platform 110, it is beneficial to raise the linear drive assembly 144 to a certain height, thus facilitating the installation of the second linear drive module 150 and the third linear drive module 160. Additionally, by providing a slide rail 146 on the first vertical frame 142 that is consistent with the transmission direction of the linear drive assembly 144, when the linear drive assembly 144 drives the mounting plate 148 to move, since the mounting plate 148 is slidably connected to the slide rail 146, the slide rail 146 can be used to limit the position of the mounting plate 148 to ensure the straightness and stability of the mounting plate 148 during movement, improve the reliability during transmission, so that when the second linear drive module 150 and the third linear drive module 160 on the mounting plate 148 are driven by the linear drive assembly 144, they can move more smoothly and reliably.

[0034] As Figure 2 , Figure 4 and Figure 5 shown, the clamping assembly 170 includes a support frame 171 connected to the second linear drive module 150, and a jaw cylinder 172 and a first rotary table 173 provided on the support frame 171. A connecting arm 174 is provided on the first rotary table 173, and a suction nozzle 175 is provided at the end of the connecting arm 174. A first jaw 176 and a second jaw 177 are rotatably connected to the suction nozzle 175, and an elastic member is provided between the first jaw 176 and the second jaw 177 so that one ends of the first jaw 176 and the second jaw 177 respectively abut against the inner sides of the jaw fingers 1722 of the jaw cylinder 172. Among them, the first rotary table 173 is used to drive the connecting arm 174 to swing in the horizontal direction.

[0035] Specifically, the clamping assembly 170 mainly realizes the drive for clamping the cable connector through the jaw cylinder 172 connected to the support frame 171. When the jaw cylinder 172 operates, it drives the jaw fingers 1722 to approach or separate from each other. At this time, through the cooperation of the first jaw 176 and the second jaw 177 rotatably connected to the suction nozzle 175, the clamping of the cable connector is realized. It should be noted that one ends of the first jaw 176 and the second jaw 177 that cooperate with the jaw fingers 1722 have an elastic force to move away from each other under the action of the elastic member, so as to facilitate the abutting cooperation with the jaw fingers 1722.

[0036] In addition, through the connecting arm 174 connected to the support frame 171 and the suction nozzle 175 provided on the connecting arm 174, when the cable connector is clamped by the first jaw 176 and the second jaw 177, the suction nozzle 175 can play an auxiliary fixing role for the cable connector to prevent the cable connector from accidentally falling off. It should be noted that the connecting arm 174 is connected to the support frame 171 through the first rotary slide 173. The first rotary slide 173 is used to drive the connecting arm 174 to swing in the horizontal direction, thereby driving the deflection angle of the first jaw 176 and the second jaw 177 to swing and move, so that the cable connector has more degrees of freedom during alignment, which is beneficial to improving the alignment accuracy between the cable connector and the optical module.

[0037] As Figure 6 shown, an extension arm 178 is further provided on the connecting arm 174. An elastic clip 1782 is provided on the extension arm 178. Grooves are provided on the opposite side surfaces of the elastic clip 1782. The elastic clip 1782 is used to clamp the cable connected to the cable connector.

[0038] Specifically, by providing the extension arm 178 on the connecting arm 174, when the cable connector is clamped by the clamping assembly 170, the cable can be clamped by the elastic clip 1782 on the extension arm 178, preventing the cable from being wound around other components during the movement of the cable connector, resulting in mechanical failures or damage to the cable, which is beneficial to improving the reliability during coupling.

[0039] As Figure 2 and Figure 4 shown, the UV lamp module 180 includes a plurality of UV lamps 182. The UV lamps 182 are arranged circumferentially around the suction nozzle 175, and the UV lamps 182 are connected to the support frame 171 through connectors 184.

[0040] Specifically, the UV lamps 182 and the connectors 184 are arranged in one-to-one correspondence. The connectors 184 can be directly connected to the support frame 171 as needed, or can be connected to the support frame 171 through the extension arm 178 or the connecting arm 174, as long as it is convenient for the installation of the UV lamps 182. By adopting the above method, the coupling and dispensing points can be irradiated comprehensively to ensure the UV curing effect and curing efficiency.

[0041] As Figure 2 and Figure 3 shown, the dispensing assembly 162 includes a mounting seat 1622 connected to the third linear drive module 160, and a dispensing controller 1624 provided on the mounting table 110. The mounting seat 1622 is used to mount the dispensing cylinder 1626, and the dispensing controller 1624 is used to connect to the dispensing cylinder 1626 to control the glue output of the dispensing cylinder 1626; the vision module 164 includes a mounting bracket 1642 connected to the mounting seat 1622, and a camera 1644 provided on the mounting bracket 1642.

[0042] Specifically, the dispensing cylinder 1626 is a consumable required for dispensing. The corresponding glue is inside the dispensing cylinder 1626. When dispensing operation is required, the dispensing cylinder 1626 needs to be installed on the mounting base 1622 and connected to the dispensing controller 1624 to control the glue output volume and the corresponding glue output time of the dispensing cylinder 1626, so as to achieve the dispensing and fixing after coupling. In addition, in order to ensure the accuracy during dispensing, it is necessary to identify the dispensing position through the camera 1644 connected to the mounting frame 1642 to ensure the accuracy of the dispensing position.

[0043] Such as Figure 1 and Figure 7 As shown in the figure, the first positioning table 120 includes a second vertical frame 122 provided on the mounting table 110 and a first fixture 124 provided on the second vertical frame 122. The first fixture 124 is used to fix the cable connector. A support rod 116 is also provided on the mounting table 110, and a fork head 1162 is provided on the support rod 116. The fork head 1162 is used to place the cable connected to the cable connector.

[0044] By adopting the above method, when the cable connector is placed on the first fixture 124, the cable can be placed on the plug, avoiding the cable directly sagging due to gravity, and it is more convenient to clamp the cable through the elastic clip 1782.

[0045] Such as Figure 1 and Figure 8 As shown in the figure, the second positioning table 130 includes a positioning plate 132 connected to the mounting table 110, a first translation slide 133 provided on the positioning plate 132, a second rotation slide 134 provided on the first translation slide 133, a third rotation slide 135 provided on the second rotation slide 134, a second translation slide 136 provided on the third rotation slide 135, and a second fixture 137 provided on the second translation slide 136. The second fixture 137 is used to fix the optical module. Among them, the driving directions of the first translation slide 133 and the second translation slide 136 are the first direction and the second direction perpendicular to the horizontal plane, and the driving direction of the second translation slide 136 is consistent with the extending direction of the slide rail 146. The second rotation slide 134 is used to drive the second fixture 137 to pitch along the second direction, and the third rotation slide 135 is used to drive the second fixture 137 to pitch along the first direction.

[0046] Specifically, the second positioning platform 130 is connected to the installation platform 110 through a positioning plate 132, facilitating the installation of the second positioning platform 130. Through the cooperation of the first translation slide 133 and the second translation slide 136, the second jig 137 can be moved along the first direction and the second direction. In combination with the cooperation of the second linear drive module 150, the movement in three mutually perpendicular directions in space can be achieved. Additionally, through the cooperation of the second rotary slide 134 and the third rotary slide 135, the second jig 137 can pitch along the first direction and the second direction. In combination with the swing of the first clamping jaw 176 and the second clamping jaw 177 driven by the first rotary slide 173 in the horizontal direction, the deflection of the angles of the cable connector and the optical module can be corrected, ensuring the required positioning accuracy.

[0047] As Figure 2 shown, a fan 190 is further provided on the installation platform 110, and the air outlet of the fan 190 faces the second jig 137.

[0048] By adopting the above method, after the dispensing is completed, the blowing of the fan 190 can strengthen the air flow, which is beneficial to accelerating the solidification of the glue, so as to improve the efficiency of bonding and fixing.

[0049] As Figure 2 shown, in an alternative embodiment of the present application, a plurality of positioning holes 118 are arranged in an array on the installation platform 110, and the positioning holes 118 are used for installing the first positioning platform 120, the second positioning platform 130, and the first linear drive module 140.

[0050] By adopting the above method, it is convenient for the first positioning platform 120, the second positioning platform 130, and the first linear drive module 140 to be set at the required positions according to needs, which is more convenient for the installation and positioning of the first positioning platform 120, the second positioning platform 130, and the first linear drive module 140. Moreover, the versatility of the installation platform 110 can be improved, facilitating the addition and subtraction of function modules on the basis of the already installed ones.

[0051] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
