Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing equipment technology, and in particular to an integrated optical fiber coating device. Background Technology

[0002] Fiber coating involves applying a layer of fiber adhesive to the surface of a bare optical fiber and then curing it to restore or enhance the original physical properties of the fiber. It plays an important role in various fields such as fiber optic communication, fiber lasers, and fiber optic sensing technology.

[0003] Currently, fiber coating is typically performed using fiber coating machines. Existing fiber coating machines usually include two clamps. During coating, the two ends of the fiber are clamped by the clamps, and then the coating head applies adhesive evenly to the surface of the fiber. After coating, the fiber is cured. However, the coating process requires manual observation and control of the fiber coating length, and the coating accuracy is controlled manually, which can easily lead to poor consistency in processing quality. Furthermore, the manual workload is high, making it unsuitable for mass production and continuous operation. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated optical fiber coating device, which has the advantages of realizing automatic glue injection control and improving coating accuracy.

[0005] The objective of this utility model is achieved through the following technical solution: According to an embodiment of this disclosure, an integrated optical fiber coating apparatus is provided, comprising: abutment; At least two sets of clamping assemblies supported on the base and arranged opposite each other are used to clamp and fix the optical fiber to be processed; The adhesive coating mold is located between the two clamping components. When the optical fiber to be processed is clamped in the clamping components, its adhesive coating part is located inside the adhesive coating mold. The glue injection module is used to connect with the glue coating mold to inject glue into the glue coating mold and coat it onto the surface of the optical fiber to be processed. A visual inspection device supported on the base is used to collect real-time image information inside the coating mold to determine the flow position of the adhesive inside the coating mold. An ultraviolet light source mounted on the coating mold is used for curing the colloid; and, The main controller is communicatively connected to the dispensing module and the vision inspection device, and is used to control the dispensing module to stop operating and the ultraviolet light source to start performing the curing action when the vision inspection device detects that the flow position of the adhesive has reached a predetermined threshold.

[0006] To achieve the above technical solution, during optical fiber coating, the optical fiber to be processed is clamped and fixed in a straightened state using a clamping assembly. At this time, the coating area of ​​the optical fiber is located inside the coating mold. After the coating mold is closed, the main controller controls the injection module to inject adhesive into the coating mold. The adhesive spreads and coats the surface of the optical fiber in the mold. Simultaneously, a vision detection device collects real-time image information inside the coating mold and transmits it to the main controller. The main controller determines whether the flow position of the adhesive has reached a predetermined threshold based on this real-time image information. When the threshold is reached, the main controller controls the injection module to stop the operation and ends the injection. It also controls the ultraviolet light source to start irradiating the coating area for curing. After curing, the mold is opened and the cured optical fiber is removed, allowing for the next optical fiber coating operation. The cooperation between the coating mold and the injection module ensures the uniformity of the adhesive coating. The vision detection device detects the flow position of the adhesive, achieving automatic stopping of the injection operation and achieving more precise control of the amount of adhesive injected. It can also automatically start the ultraviolet light source for curing, ensuring the forming quality and operational efficiency of the coating layer and meeting the needs of batch continuous production.

[0007] In some exemplary embodiments, the clamping assembly includes: a sliding stage fixed to the base, and a fixing clamp slidably mounted on the sliding stage for clamping the optical fiber to be processed.

[0008] To achieve the above technical solution, the optical fiber to be processed is held and fixed by a clamp. The position of the clamp can be adjusted by the sliding stage. When the coating centering offset is detected in the coated optical fiber, the overall position of the optical fiber can be adjusted by sliding the clamp to quickly adjust the centering of the optical fiber coating. The adjustment process is faster and more convenient, and can effectively correct the offset problem and improve the coating accuracy.

[0009] In some exemplary embodiments, the coating mold includes an upper mold and a lower mold that cooperate with each other, and a coating cavity is formed between the upper mold and the lower mold for accommodating the coating part of the optical fiber to be processed, and the lower mold and / or the upper mold are provided with a light-transmitting area corresponding to the coating cavity for the visual inspection device to capture images.

[0010] To achieve the above technical solution, the adhesive can be uniformly coated on the surface of the optical fiber by cooperating with the adhesive coating mold cavity, and the setting of the light-transmitting area allows the visual inspection device to clearly capture the flow position of the adhesive in the mold.

[0011] In some exemplary embodiments, a positioning component is further provided between the upper mold and the lower mold.

[0012] Implementing the above technical solution enables precise alignment between the upper and lower molds, improving the accuracy of mold closing.

[0013] In some exemplary embodiments, the lower mold is also provided with at least one spare upper mold.

[0014] By implementing the above technical solution, when the upper mold malfunctions or fails, it can be directly disassembled and replaced with a spare upper mold without the need for a complicated debugging process, thereby reducing the time spent on maintenance and improving the continuity of coating operations.

[0015] In some exemplary embodiments, the ultraviolet light source is disposed on the upper mold and / or lower mold near the adhesive coating cavity.

[0016] The above technical solution improves curing efficiency.

[0017] In some exemplary embodiments, the lower mold has an injection hole located in the middle of the coating cavity, and the injection module is connected to the injection hole to inject adhesive into the coating cavity.

[0018] The above technical solution enables the docking of the lower mold and the injection module.

[0019] In some exemplary embodiments, the visual inspection device employs a video microscope.

[0020] In summary, compared with the prior art, this utility model has the following beneficial effects: This invention provides an integrated optical fiber coating device, comprising: a base; at least two sets of clamping assemblies supported on the base and arranged opposite to each other for clamping and fixing the optical fiber to be processed; a coating mold located between the two clamping assemblies, wherein when the optical fiber to be processed is clamped in the clamping assemblies, its coating portion is located within the coating mold; a dispensing module for engaging with the coating mold to inject adhesive into the coating mold to coat the surface of the optical fiber to be processed; a vision inspection device supported on the base for acquiring real-time image information within the coating mold to determine the flow position of the adhesive within the coating mold; an ultraviolet light source supported on the coating mold for curing the adhesive; and a main controller communicatively connected to the dispensing module and the vision inspection device, for controlling the dispensing module to stop operating and the ultraviolet light source to start performing the curing action when the vision inspection device detects that the flow position of the adhesive has reached a predetermined threshold. During fiber coating, the fiber to be processed is clamped and fixed in a straightened state using a clamping assembly. At this time, the coating area of ​​the fiber is located inside the coating mold. After the coating mold is closed, the main controller controls the injection module to inject adhesive into the coating mold. The adhesive spreads and coats the surface of the fiber within the mold. Simultaneously, a vision inspection device collects real-time image information from inside the coating mold and transmits it to the main controller. The main controller determines whether the flow position of the adhesive has reached a predetermined threshold based on this real-time image information.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 and Figure 2 As shown, this utility model provides an integrated optical fiber coating device, including: a base 10; at least two sets of clamping assemblies 20 supported on the base 10 and arranged opposite each other for clamping and fixing the optical fiber to be processed; a coating mold located between the two clamping assemblies 20, wherein when the optical fiber to be processed is clamped in the clamping assembly 20, its coating part is located inside the coating mold; a dispensing module 40 for connecting with the coating mold to inject adhesive into the coating mold to coat the surface of the optical fiber to be processed; a vision inspection device 50 supported on the base 10 for collecting real-time image information inside the coating mold to determine the flow position of the adhesive inside the coating mold; an ultraviolet light source 60 supported on the coating mold for curing the adhesive; and a main controller 70, which is communicatively connected to the dispensing module 40 and the vision inspection device 50, for controlling the dispensing module 40 to stop operating and the ultraviolet light source 60 to start performing the curing operation when the vision inspection device 50 detects that the flow position of the adhesive has reached a predetermined threshold.

[0026] Specifically, the clamping assembly 20 includes: a sliding stage 21 fixed to the base 10, and a fixing clamp 22 slidably mounted on the sliding stage 21 for clamping the optical fiber to be processed. The sliding stage 21 is fixed to the base 10 by screws, and the fixing clamp 22 can adopt an existing clamping structure. The sliding stage 21 can drive the fixing clamp 22 to slide and adjust manually or electrically, for example, by setting a manual screw adjustment structure or an electric lead screw adjustment structure. The fixing clamp 22 clamps and fixes the optical fiber to be processed. The setting of the sliding stage 21 can adjust the position of the fixing clamp 22. When the coating centering offset is detected in the coated optical fiber, the fixing clamp 22 can be slid to adjust the overall position of the optical fiber, and the centering of the optical fiber coating can be quickly adjusted. The adjustment process is faster and more convenient, and can effectively correct the offset problem and improve the coating accuracy.

[0027] The coating mold includes an upper mold 31 and a lower mold 32 that cooperate with each other. A coating cavity 33 is formed between the upper mold 31 and the lower mold 32 to accommodate the coating part of the optical fiber to be processed. The lower mold 32 and / or the upper mold 31 are provided with light-transmitting areas corresponding to the coating cavity 33 for the vision inspection device 50 to capture images. It can be understood that after the upper mold 31 and the lower mold 32 are closed, there is a certain gap between the optical fiber to be processed and the coating cavity 33 to form a coating layer. In order to facilitate processing, transparent materials such as glass and acrylic sheets can be used to process the coating mold. Thus, the entire upper mold 31 and the lower mold 32 can be used as light-transmitting areas. The coating cavity 33 cooperates with the optical fiber so that the adhesive can be uniformly coated on the surface of the optical fiber. The setting of the light-transmitting areas allows the vision inspection device 50 to clearly capture the flow position of the adhesive in the mold.

[0028] Furthermore, a positioning component 34 is provided between the upper mold 31 and the lower mold 32. The positioning component 34 can be, for example, a matching guide post and guide hole / guide sleeve, so that the upper mold 31 and the lower mold 32 can be accurately aligned, improving the accuracy of mold closing. At least one spare upper mold 3531 is also provided in the lower mold 32. When the upper mold 31 is abnormal or malfunctions, the spare upper mold 3531 can be directly disassembled and replaced without complicated debugging procedures, reducing maintenance time and improving the continuity of coating operations.

[0029] The glue injection module 40 can adopt an existing structure, which typically includes a glue injection pump and a glue injection head. The glue injection pump is connected to a glue storage tank and is used to pump the glue from the storage tank and inject it into the glue coating cavity 33 through the glue injection head. A glue injection hole 36 is provided on the lower mold 32 in the middle of the glue coating cavity 33. The glue injection module 40 is connected to the glue injection hole 36 to inject the glue into the glue coating cavity 33. It can be understood that the glue injection head and the glue injection hole 36 are usually sealed to achieve the docking of the lower mold 32 and the glue injection module 40.

[0030] The ultraviolet light source 60 is located on the upper mold 31 and / or the lower mold 32 near the adhesive coating cavity 33. The ultraviolet light can be a lamp tube or several point light sources distributed in a linear array on both sides of the adhesive coating cavity 33 to improve curing efficiency. The visual inspection device 50 is preferably a video microscope.

[0031] The main controller 70 may include, for example, a microcontroller unit (MCU), a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), a programmable controller, a programmable logic device (PLD), or other similar devices or combinations thereof, and this invention is not limited thereto. Alternatively, in some embodiments, the functions of the main controller 70 may be implemented by one or more circuits, and this invention does not limit the hardware implementation of the functions of the main controller 70. The main controller 70 has an interface module for communication with the dispensing module 40, the ultraviolet light source 60, and the vision inspection device 50. Typically, the main controller 70 is connected to the controller of the dispensing motor in the dispensing module 40 and to the start controller of the ultraviolet light source 60.

[0032] During optical fiber coating, the optical fiber to be processed is clamped and fixed in a straightened state by the clamping assembly 20. At this time, the coating area of ​​the optical fiber to be processed is located inside the coating mold. After the coating mold is closed, the main controller 70 controls the injection module 40 to inject adhesive into the coating mold. The adhesive spreads and coats the surface of the optical fiber to be processed in the mold. At the same time, the vision detection device 50 collects real-time image information inside the coating mold and transmits it to the main controller 70. The main controller 70 determines whether the flow position of the adhesive has reached a predetermined threshold based on the real-time image information. When the threshold is reached, the main controller 70 controls the process to proceed. The glue injection module 40 stops its operation to finish the glue injection, and the ultraviolet light source 60 is activated to irradiate the coated area for curing. After curing, the mold is opened and the cured optical fiber is removed, ready for the next optical fiber coating operation. The cooperation between the coating mold and the glue injection module 40 ensures the uniformity of the glue coating. The vision detection device 50 detects the flow position of the glue and realizes the automatic stop of the glue injection operation, achieving more precise control of the glue injection amount. It can also automatically activate the ultraviolet light source 60 for curing, ensuring the forming quality of the coating layer and the efficiency of the operation, meeting the needs of batch continuous production.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
