[0030] At present, for the optical modules predicted to be qualified for the whole machine, specific glue needs to be applied at the fusion point and YB disk area. This glue is a mixture of two groups of glue, AB. The glue mixing has certain ratio requirements and needs to be fully mixed. In order to ensure that the applied glue is wrapped around the optical fiber, vacuum treatment is required. The glue solidifies for 4 hours at room temperature for each device.
[0031] However, the natural solidification of glue at room temperature will cause an increase in the optical module cache space, which cannot meet the post-process testing and poses a high problem.
[0032] In order to solve the above problems, the utility model provides a drying device 100. Figures 1 to 3 This is a specific embodiment of the drying equipment provided by the utility model.
[0033] See also Figures 1 to 3 The drying device 100 includes a frame 1, a drying device 2, and a conveying structure 3. The frame 1 has a front buffer station, a drying station, and a rear buffer station arranged at intervals in the horizontal direction. The drying device 2 is arranged on the frame 1 and is located at the drying station. The drying device 2 includes a drying cabin 21. The drying cabin 21 forms a drying channel that is arranged through in the horizontal direction. The side walls and top walls of the drying channel are both provided with electric heating wires 22. The conveying structure 3 is installed on the frame 1. The conveying structure 3 is arranged through the front buffer station, the drying station, and the rear buffer station, so as to drive the optical module located at the front buffer station to pass through the drying channel and then be transmitted to the rear buffer station.
[0034] In the technical solution provided by the utility model, the optical module coated with glue is first transmitted to the front cache station through the previous processing structure, waiting to enter the drying channel for drying. When there are no other optical modules being dried in the drying channel, the transmission structure 3 drives the optical module coated with glue to move horizontally to enter the drying channel. When the optical module coated with glue moves to the drying station, the transmission structure 3 stops moving, and the multiple electric heating wires 22 located on the side walls and top walls of the drying channel dry and solidify the glue on the optical module. After the drying work is completed, the transmission structure 3 drives the optical module to continue to move horizontally to the rear cache station for cooling treatment. After the cooling is completed, the optical module can be moved to the next processing structure. Such a setting increases the temperature of the glue in the natural state by baking, thereby accelerating the solidification speed of the glue, reducing the cache space of the optical module, and meeting the post-process testing.
[0035] It can be understood that in the embodiment of the utility model, at least two drying stations are provided, and the two drying stations are arranged at intervals along the conveying direction of the conveying structure 3, and are both located in the drying chamber 21, so that the drying chamber 21 can simultaneously meet the drying work of multiple optical modules.
[0036] In addition, in the embodiment of the present invention, the temperature of the drying work is set to at least 80° C., and the drying time is determined according to the drying temperature and the processing rate of the previous processing structure, and the present invention does not impose any restrictions on this.
[0037] Furthermore, the conveying structure 3 includes a plurality of conveyor belt segments 31 spaced apart in the longitudinal direction, and the plurality of conveyor belt segments 31 move synchronously. With such a configuration, the plurality of conveyor belt segments 31 spaced apart in the longitudinal direction can jointly carry the optical module coated with glue, so that the optical module coated with glue can stably move in the lateral direction, thereby ensuring the stability of the transport of the conveying structure 3.
[0038] It should be noted that the conveyor belt segment 31 can be configured as a PVC conveyor belt, a nylon conveyor belt, a stainless steel conveyor belt, or other conveyor belt forms, and the present invention does not impose too many restrictions on this.
[0039] For example, in an embodiment of the present utility model, the conveyor belt segment 31 is configured as a double-speed chain, and the conveying assembly also includes a driving gear wheel set, a chain, and a motor. The double-speed chain is connected to the driving gear wheel set, and then connected to the motor through the chain. The motor is used to drive the double-speed chain to transmit forward and backward and upward. Setting the conveyor belt segment 31 as the double-speed chain can make the conveying speed more precise and stable, ensure precise synchronous conveying, and the double-speed chain has a greater transmission capacity and can carry a larger load.
[0040] Furthermore, the conveying structure 3 also includes a plurality of limit blocks 32, and the plurality of limit blocks 32 are arranged on each of the conveying belt segments 31 at intervals along the conveying direction of the conveying belt segment 31, and two adjacent limit blocks 32 are used to jointly limit the position of the optical module. In an embodiment of the utility model, the spacing between the plurality of limit blocks 32 is equivalent to the distance between each station in the lateral direction. In this way, when each of the conveying belt segments 31 simultaneously drives a plurality of optical modules coated with glue to move in the lateral direction, the positions of the plurality of optical modules coated with glue can be limited, so that at least one optical module coated with glue is placed on the front cache station, the drying station and the rear cache station, that is, it is ensured that each area can be placed with an optical module coated with glue, thereby ensuring the drying efficiency of the drying equipment 100.
[0041] Of course, in the embodiment of the present invention, it can also be arranged that only one or part of the conveyor belt segments 31 are provided with a plurality of the limit blocks 32, so that the position of the optical module can also be limited, and the present invention does not impose any limitation on this.
[0042] In order to ensure the stability of the drying temperature in the drying chamber 21, the drying device 2 also includes two sealing doors 23, which are movably installed at the two ends of the drying channel along the horizontal direction, so as to be able to block or reveal the drying channel setting. In this way, when the conveying structure 3 drives the optical module to move in front of one of the sealing doors 23, the corresponding sealing door 23 is opened, and the conveying structure 3 continues to drive the optical module to move into the drying chamber 21 to perform the drying work; after the drying work is completed, the other sealing door 23 is opened, and the conveying structure 3 drives the optical module to move out of the drying chamber 21. The two sealing doors 23 are only opened when the conveying structure 3 drives the optical module to move in or out of the drying chamber 21, and are in a closed state at other times to maintain the temperature in the drying chamber 21.
[0043] It should be noted that, in an embodiment of the utility model, the two sealing doors 23 are opened and closed at the same time, a front cache station is arranged outside the sealing door 23 near the loading station, and a rear cache station is arranged outside the sealing door 23 near the unloading station. When the two sealing doors 23 are opened, optical modules are placed on the front cache station and the drying station. At this time, the conveying structure 3 drives the two optical modules to move at the same time, and the two optical modules are respectively moved to the drying station and the rear cache station. The two sealing doors 23 are closed, and the next drying work is carried out. In this way, there can always be at least one optical module in the drying cabin 21, thereby shortening the time required for the drying and solid glue process.
[0044] Furthermore, the drying device 2 also includes a plurality of temperature sensors 24, and the plurality of temperature sensors 24 are arranged in the drying channel at intervals along the horizontal or vertical direction. The arrangement of the plurality of temperature sensors 24 can monitor the temperature in the drying chamber 21 at all times. When the temperature in the drying chamber 21 is higher than the preset drying temperature, the plurality of electric heating wires 22 stop working; when the temperature in the drying chamber 21 is lower than the preset drying temperature, the plurality of electric heating wires 22 continue to work, thereby maintaining the temperature in the drying chamber 21 stable.
[0045] Furthermore, the drying device 2 also includes an exhaust fan 25, which is arranged at the upper end of the drying chamber 21 and is connected to the drying channel. When the drying device 2 stops being used, in order to quickly reduce the temperature in the drying channel, the drying device 2 also includes the exhaust fan 25. At this time, it is only necessary to turn on the exhaust fan 25. The exhaust fan 25 can discharge the high-temperature air in the drying chamber 21, and then allow the low-temperature air from the outside to flow into the drying chamber 21 for heat exchange, so that the temperature in the drying chamber 21 quickly drops to room temperature.
[0046] In order to ensure the safety of the drying equipment 100, the drying equipment 100 also includes an emergency stop part and a release part arranged on the frame 1 along the lateral interval, the emergency stop part is located at the front buffer station, and the release part is located at the rear buffer station, the emergency stop part and the release part are both electrically connected to the conveying structure 3, and can respectively shut down and start the conveying structure 3, so that when the drying equipment 100 fails, the operator can operate the emergency stop part to stop the operation of the conveying structure 3, and then stop the operation of the drying equipment 100, when the operator is required to operate manually, the operator can operate the release part to control the conveying distance of the conveying structure 3 to ensure the stability of the operation of the drying equipment 100.
[0047] The drying chamber 21 is also provided with safety gratings on both sides along the lateral direction. The safety gratings can avoid safety accidents caused by operator misoperation, so as to further ensure the safety of the drying device 100 .
[0048] Specifically, the drying device 100 also includes a cooling structure, and the cooling structure includes a circulating water pipeline, which is located on the post-buffer station and is used to accommodate circulating water. The two pipe openings of the circulating water pipeline are used to connect the optical module. From the above content, it can be seen that when the optical module is removed from the drying chamber 21, the temperature is relatively high. Such a setting can cool the optical module through the circulating water in the circulating water pipeline. After the optical module is cooled, the optical module is purged through the compressed air system in the production workshop to remove the residual water stains on the optical module to ensure that there is no water stain in the optical module, and then it is transported to the next processing structure.
[0049] It should be noted that a speed regulating hand valve is provided on the circulating water pipeline, and the operator can adjust the water inflow of the circulating water by adjusting the opening of the speed regulating hand valve.
[0050] In an embodiment of the utility model, the drying device 100 further includes two position sensors 4, which are respectively located at the front buffer station and the rear buffer station, and the position sensors 4 are used to detect the position of the optical module. The position sensor 4 is used to detect the position of the optical module to determine whether the optical module has reached the front buffer station or the rear buffer station, and the two position sensors 4 are used to ensure the accuracy of various operations, thereby ensuring the accuracy of the drying operation.
[0051] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
