Description

Technical Field

[0001] This utility model relates to the technical field of fiber optic grating coating, and in particular to a fiber optic grating coating apparatus. Background Technology

[0002] Fiber Bragg grating coating is one of the key processes in its fabrication. Its main purpose is to optimize optical performance, enhance functionality, or protect fiber Bragg gratings by depositing thin films of specific materials on the surface or end face of the grating. Currently, fiber Bragg grating coating is generally achieved by using a fiber coating machine to deposit a film on the surface of the fiber Bragg grating. For example, the utility model patent with patent application number 201520560068.5 discloses a fiber coating machine, which mainly consists of a mold and a glue injection mechanism. The mold has a cavity. During fiber Bragg grating coating, the fiber is placed on the mold, so that the grating on the fiber is located within the cavity of the mold, and then the mold fixes the fiber Bragg grating. Then, the glue injection mechanism injects protective glue into the cavity of the mold, thus forming a protective film on the grating surface. However, this method has the following problems: after the fiber Bragg grating is coated and removed from the mold cavity, some protective glue may remain inside the mold cavity. These residues are highly viscous, and during long-term production operations, frequent manual removal of these residues from the mold is labor-intensive and inconvenient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a fiber grating coating device that can help workers clean the residue inside the lower and upper mold cavities, reduce labor intensity, is easy to use, and is highly practical.

[0004] This utility model discloses a fiber optic grating coating device, comprising a base plate, a support platform, a lower mold, and an upper mold. The support platform is fixedly mounted on the upper end of the base plate, the lower mold is fixedly mounted on the upper end of the support platform, and the upper mold is located above the lower mold. Both the upper and lower molds have cavities. The device also includes a lifting mechanism, a glue injection mechanism, and a cleaning mechanism. The output end of the glue injection mechanism is connected to the cavity of the lower mold, and the glue injection mechanism has a glue injection function. The upper mold is mounted on the lifting mechanism, which is used to lift and lower the upper mold. The cleaning mechanism is mounted on the support platform and is used to clean the lower and upper molds. During the glue injection of the fiber optic grating, the optical fiber is placed on the lower mold. The upper mold is then lowered via a lifting mechanism, bringing it into contact with the lower mold. This positions the fiber optic grating within the cavity formed by the upper and lower molds. A gluing mechanism then injects gluing into the cavities of the upper and lower molds. After a period of time, the protective adhesive cures on the grating surface, forming a protective film. The upper mold is then raised, and the coated fiber optic grating is removed from both molds. Finally, a cleaning mechanism removes any residue from the cavities of the upper and lower molds. This process helps workers clean the cavities of the upper and lower molds, reducing labor intensity. It is convenient to use and highly practical.

[0005] Preferably, the glue injection mechanism includes a glue injection pump, a glue discharge pipe, a delivery pipe, and a glue storage cylinder. The glue injection pump is fixedly mounted on the support platform. The output end of the glue injection pump is connected to the cavity of the lower mold through the glue discharge pipe. A valve is installed on the glue discharge pipe. The input end of the glue injection pump is connected to the glue storage cylinder through the delivery pipe. The glue storage cylinder stores protective glue. When it is necessary to inject glue into the cavity of the lower mold, the glue injection pump is turned on, so that the protective glue in the glue storage cylinder is delivered to the lower mold in sequence through the delivery pipe, the glue injection pump, and the glue discharge pipe. This facilitates the delivery of the protective glue.

[0006] Preferably, the lifting mechanism includes a hoisting frame, a hydraulic cylinder A, and a push rod. The hydraulic cylinder A is fixedly installed on the upper end of the hoisting frame, and the push rod is slidably installed on the hoisting frame. The upper end of the push rod is connected to the output end of the hydraulic cylinder A, and the upper mold is fixedly installed on the lower end of the push rod. The hoisting frame is fixedly hoisted on a fixed frame in the workshop. When adjusting the height of the upper mold, the hydraulic cylinder A is opened, and the hydraulic cylinder A adjusts the height of the upper mold through the push rod. This facilitates the adjustment of the height of the upper mold.

[0007] Preferably, the cleaning mechanism includes an electric slide rail, a sliding plate, a fixed frame, a hydraulic cylinder B, a lifting rod, a moving block, a drive motor, a rotating shaft, a spraying mechanism, and a dust collection mechanism. The electric slide rail is fixedly installed at the rear of the support platform. The sliding plate is installed on the electric slide rail and is used to move the sliding plate left and right. The fixed frame is fixedly installed at the upper end of the sliding plate. The hydraulic cylinder B is fixedly installed at the upper end of the fixed frame. The lifting rod is slidably installed on the fixed frame, and its upper end is connected to the output end of the hydraulic cylinder B. The moving block is fixedly installed at the lower end of the lifting rod and is slidably installed on the fixed frame. The drive motor is fixedly installed on the moving block, and the rotating shaft is rotatably installed on the moving block. The input end of the rotating shaft is connected to the drive motor. The spraying mechanism and the dust collection mechanism are both installed on the rotating shaft and the base plate. The rotating shaft is located between the upper mold and the lower mold. The drive motor is a motor with angle self-locking capability. When the upper mold descends, the electric slide rail is opened, causing the sliding plate to move to the left. The plate moves the fixed frame, moving block, and rotating shaft to the left, preventing the rotating shaft from interfering with the area between the upper and lower molds during descent. When cleaning the cavities of the lower and upper molds, the rotating shaft is moved between them. Taking cleaning the lower mold cavity as an example, the spraying mechanism first sprays mold cleaning agent into the cavity, softening and loosening the residue. Then, the drive motor is turned on, rotating the shaft to move the suction mechanism into the cavity. Hydraulic cylinder B is then activated, lowering the moving block via a lifting rod. The moving block adjusts the height of the suction mechanism via the rotating shaft, ensuring a suitable distance between the suction mechanism and the lower mold for suction. The suction mechanism then sucks up the residue from the lower mold for cleaning. When cleaning the upper mold, the spraying and suction mechanisms are used sequentially to clean it, facilitating the cleaning of both the lower and upper molds.

[0008] Preferably, the spraying mechanism includes a cleaning agent storage tank, a delivery pump, a delivery hose A, and a spray head. The cleaning agent storage tank is fixedly installed on the base plate. The input end of the delivery pump is connected to the cleaning agent storage tank, and the output end of the delivery pump is connected to the spray head through the delivery hose A. The spray head is fixedly installed at the lower end of the rotating shaft and is equipped with a valve. The spray head is located between the lower mold and the upper mold. When cleaning the lower mold, the delivery pump is turned on, so that the mold cleaning agent in the cleaning agent storage tank is sprayed onto the lower mold sequentially through the delivery pump, delivery hose A, and spray head. This facilitates the cleaning of residues in the lower and upper mold cavities.

[0009] Preferably, the vacuuming mechanism includes a vacuum cleaner, a delivery hose B, and a suction pipe. The input end of the vacuum cleaner is connected to the suction pipe through the delivery hose B. The suction pipe is installed on the rotating shaft and is located between the lower mold and the upper mold. When the vacuum cleaner is turned on, the residue on the lower mold or the upper mold can enter the vacuum cleaner through the suction pipe and the delivery hose B, which facilitates the cleaning of the residue.

[0010] Preferably, the hydraulic cylinder A is equipped with a dust cover.

[0011] Compared with the prior art, the advantages of this utility model are: it can help workers clean the residue in the lower mold and upper mold cavity, reduce labor intensity, is convenient to use, and is highly practical. Attached Figure Description

[0020] like Figures 1 to 5The fiber grating coating device of this invention includes a base plate 1, a support platform 2, a lower mold 3, an upper mold 4, a lifting mechanism, a glue injection mechanism, and a cleaning mechanism. The support platform 2 is fixedly installed on the upper end of the base plate 1, the lower mold 3 is fixedly installed on the upper end of the support platform 2, and the upper mold 4 is located above the lower mold 3. Both the upper mold 4 and the lower mold 3 have cavities.

The upper mold 4 is installed on the lifting mechanism, which is used to lift and lower the upper mold 4. The cleaning mechanism is installed on the support platform 2 and is used to clean the lower mold 3 and the upper mold 4. When injecting glue into the fiber grating, the optical fiber is placed on the lower mold 3. Then, the upper mold 4 is lowered by the lifting mechanism, so that the upper mold 4 contacts the lower mold 3, and the grating on the optical fiber is located in the cavity formed by the lower mold 3 and the upper mold 4. Then, the glue injection mechanism injects glue into the cavity of the lower mold 3 and the upper mold 4. After waiting for a period of time, the protective glue cures on the surface of the grating, forming a protective film on the surface of the grating. Then, the upper mold 4 is raised, and the coated fiber grating is removed from the lower mold 3 and the upper mold 4. Then, the cleaning mechanism cleans the residue in the cavity of the lower mold 3 and the upper mold 4. This can help workers clean the residue in the cavity of the lower mold 3 and the upper mold 4, reduce labor intensity, and is convenient to use and highly practical.

[0021] like Figure 1 and Figure 3 The glue injection mechanism includes a glue injection pump 5, a glue discharge pipe 6, a delivery pipe 7, and a glue storage cylinder 8. The glue injection pump 5 is fixedly installed on the support 2. The output end of the glue injection pump 5 is connected to the cavity of the lower mold 3 through the glue discharge pipe 6. A valve is installed on the glue discharge pipe 6. The input end of the glue injection pump 5 is connected to the glue storage cylinder 8 through the delivery pipe 7. The glue storage cylinder 8 stores protective glue. When it is necessary to inject glue into the cavity of the lower mold 3, the glue injection pump 5 is turned on, so that the protective glue in the glue storage cylinder 8 is delivered to the lower mold 3 in sequence through the delivery pipe 7, the glue injection pump 5, and the glue discharge pipe 6. This facilitates the delivery of protective glue.

[0022] like Figure 3 The lifting mechanism includes a hoisting frame 9, a hydraulic cylinder A10, and a push rod 11. The hydraulic cylinder A10 is fixedly installed on the upper end of the hoisting frame 9, and the push rod 11 is slidably installed on the hoisting frame 9. The upper end of the push rod 11 is connected to the output end of the hydraulic cylinder A10, and the upper mold 4 is fixedly installed on the lower end of the push rod 11. The hoisting frame 9 is fixedly hoisted on a fixed frame in the workshop. When adjusting the height of the upper mold 4, the hydraulic cylinder A10 is opened, and the hydraulic cylinder A10 adjusts the height of the upper mold 4 through the push rod 11, which facilitates the adjustment of the height of the upper mold 4.

[0023] like Figure 1 , 34 and 5, the cleaning mechanism includes an electric slide rail 12, a sliding plate 13, a fixed frame 14, a hydraulic cylinder B15, a lifting rod 16, a moving block 17, a drive motor 18, a rotating shaft 19, a spraying mechanism, and a dust collection mechanism.

The drive motor 18 is fixedly installed on the moving block 17. The rotating shaft 19 is rotatably installed on the moving block 17. The input end of the rotating shaft 19 is connected to the drive motor 18. The spraying mechanism and the dust collection mechanism are both installed on the rotating shaft 19 and the base plate 1. The rotating shaft 19 is located between the upper mold 4 and the lower mold 3. The drive motor 18 is a motor with angle self-locking function. When the upper mold 4 descends, the electric slide rail 12 is opened. 2. Move the sliding plate 13 to the left. The sliding plate 13 drives the fixed frame 14, the moving block 17, and the rotating shaft 19 to move to the left, so that the rotating shaft 19 avoids the area between the upper mold 4 and the lower mold 3, and avoids interference between the upper mold 4 and the rotating shaft 19 when it descends. When cleaning the cavities of the lower mold 3 and the upper mold 4, move the rotating shaft 19 between the lower mold 3 and the upper mold 4. Taking the cleaning of the cavity of the lower mold 3 as an example, first, make the spraying mechanism rush towards the lower mold 3, and then spray mold cleaning agent into the cavity of the lower mold 3 through the spraying mechanism to soften and loosen the attached substances in the cavity of the lower mold 3. Then, turn on the drive. Motor 18 drives the rotating shaft 19 to rotate, causing the dust collection mechanism to rush towards the cavity of the lower mold 3. Then, hydraulic cylinder B15 is opened, and hydraulic cylinder B15 lowers the moving block 17 through lifting rod 16. The moving block 17 adjusts the height of the dust collection mechanism through rotating shaft 19, so that the distance between the dust collection mechanism and the lower mold 3 is suitable for dust collection. Then, the dust collection mechanism sucks in the residue on the lower mold 3 for cleaning. When cleaning the upper mold 4, the spraying mechanism and dust collection mechanism are used to rush towards the upper mold 4 in sequence to clean it, which facilitates the cleaning of the lower mold 3 and the upper mold 4.

[0024] like Figure 4The spraying mechanism includes a cleaning agent tank 20, a delivery pump 21, a delivery hose A22, and a spray nozzle 23.

The spray nozzle 23 is fixedly installed at the lower end of the rotating shaft 19 and is equipped with a valve. The spray nozzle 23 is located between the lower mold 3 and the upper mold 4. When cleaning the lower mold 3, the delivery pump 21 is turned on so that the mold cleaning agent in the cleaning agent tank 20 is sprayed onto the lower mold 3 in sequence through the delivery pump 21, the delivery hose A22, and the spray nozzle 23. This facilitates the cleaning of residues in the cavities of the lower mold 3 and the upper mold 4.

[0025] like Figure 4 The vacuuming mechanism includes a vacuum cleaner 24, a delivery hose B25, and a suction pipe 26. The input end of the vacuum cleaner 24 is connected to the suction pipe 26 through the delivery hose B25. The suction pipe 26 is installed on the rotating shaft 19 and is located between the lower mold 3 and the upper mold 4. When the vacuum cleaner 24 is turned on, the residue on the lower mold 3 or the upper mold 4 can enter the vacuum cleaner 24 through the suction pipe 26 and the delivery hose B25, which facilitates the cleaning of residue.
