[0055] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0056] like Figure 1 to Figure 2As shown, this embodiment provides an automatic coating device 100 for coating grease on the surface of an optical fiber. The automatic coating device 100 includes an oil supply component 10, a storage component 20, a grease coating component 30, a pulling component 70, a control device 60 and a weighing device 23.

[0057] The storage member 20 is used to store grease. The oil supply assembly 10 is arranged at intervals on one side of the storage member 20, and the oil supply assembly 10 is used to deliver grease to the storage member 20. The grease coating assembly 30 is arranged at intervals on the side of the storage member 20 away from the oil supply assembly 10. The grease coating assembly 30 is provided for the optical fiber to pass through, and the grease coating assembly 30 is connected to the storage member 20, and is used to receive the grease received by the storage member 20 and apply the grease to the surface of the optical fiber. The traction assembly 70 is used to traction the optical fiber relative to the grease coating assembly 30, so that the grease delivered to the grease coating assembly 30 can be applied to each section of the optical fiber along the longitudinal direction.

[0058] The control device 60 is connected to the traction assembly 70 by signal, and is used to collect the traction speed of the optical fiber during the monitoring time. The weighing device 23 is provided on the storage element 20, and is used to monitor the weight of the storage element 20. The weighing device 23 can be a weighing scale, which is located below the entire storage element 20, and can weigh the weight of the entire storage element 20 and the stored grease, and the weight change of the grease in the storage element 20 can be obtained according to the difference between the weights measured before and after the weighing device 23.

[0059] The control device 60 is connected to the weighing device 23 by signal, and is used to obtain the weight difference of the grease in the storage element 20 during the monitoring time, and obtain the amount of grease applied per unit length of the optical fiber after comparing the pulling speed with the weight difference. The amount of grease applied per unit length of the optical fiber refers to the total weight of the grease applied to the sections within the unit length of the optical fiber. The unit length of the optical fiber can be 1m, or 0.5m, 2m or other values. In actual measurement, the measurement value of the unit length of the optical fiber can be selected according to the adaptability of the pulling speed of the optical fiber.

[0060] In this way, the automatic coating device 100 of the present application extracts the grease in the oil supply component 10 into the storage component 20, and monitors the weight of the grease in the storage component 20 through the weighing device 23 provided in the storage component 20. The grease temporarily stored in the storage component 20 is then transported to the grease coating component 30 and coated on the outer surface of the optical fiber, thereby realizing the automatic grease coating of the optical fiber. At the same time, the control device 60 calculates the weight difference of the grease within a certain monitoring time according to the weight change of the grease in the storage component 20 recorded by the weighing device 23, and the control device 60 calculates the moving distance of the optical fiber according to the pulling speed of the pulling component 70 within the monitoring time, thereby calculating the amount of grease per unit length of the optical fiber according to the moving distance of the optical fiber and the weight difference of the grease.

[0061] Please combine again Figure 1 to Figure 2In one embodiment, the oil supply assembly 10 includes an oil storage member 11 , a liposuction device 12 and a first delivery pipeline 13 .

[0062] The oil storage member 11 is a container such as an oil barrel, and a cavity is provided inside the oil storage member 11 to store grease, and the top of the oil storage member 11 is open, so that grease can be directly poured into the oil storage member 11. The oil storage member 11 is fixed on the ground to maintain the stability of the oil storage member 11.

[0063] One end of the liposuction device 12 is connected to the oil storage member 11 , and the other end of the liposuction device 12 is connected to the storage member 20 , so as to extract the grease in the oil storage member 11 into the storage member 20 .

[0064] Specifically, the liposuction device 12 includes a screw pump 121 and a lifting mechanism 122. One end of the screw pump 121 extends into the grease in the oil storage part 11 to absorb the grease, and the other end of the screw pump 121 is connected to the first delivery pipeline 13. The end of the first delivery pipeline 13 away from the screw pump 121 is connected to the storage part 20, so that the grease stored in the oil storage part 11 is delivered to the storage part 20 through the screw pump 121.

[0065] The screw pump 121 can be placed along the extension direction of the oil storage member 11, or can be placed obliquely relative to the extension direction of the oil storage member 11. It is understandable that, in addition to the screw pump 121, the liposuction device 12 can also use other devices that can transport grease.

[0066] The lifting mechanism 122 is a cylinder lifting platform, a hydraulic lifting platform or a scissor lift, etc., and is arranged outside the oil storage part 11. The screw pump 121 is installed on the lifting mechanism 122, and is used to move in the vertical direction under the drive of the lifting mechanism 122, so that the driving end of the screw pump 121 is inserted into the grease or extracted from the grease.

[0067] Please combine again Figure 1 to Figure 2 In one embodiment, the control device 60 is connected to the liposuction device 12 by signal, and is used to control the start and stop of the liposuction device 12. When there is less grease in the storage unit 20, the control device 60 controls the liposuction device 12 to start and pump the grease in the oil storage unit 11 into the storage unit 20, and the control device 60 controls the liposuction device 12 to stop working when the grease in the storage unit 20 reaches a preset value.

[0068] Furthermore, the storage element 20 includes a main body 21 and a cover plate 22. A storage cavity 210 is provided inside the main body 21, and the storage cavity 210 is used to store grease. The storage cavity 210 is formed by extending downward from the end surface of the top end of the main body 21. The cover plate 22 is provided on the top end of the main body 21 to close the storage cavity 210, so that the storage cavity 210 is a sealed cavity. An oil inlet channel 211 and a recovery channel 213 are provided on the outer peripheral surface of the main body 21, and an oil outlet channel 212 is provided at the bottom end of the main body 21. The oil inlet channel 211, the oil outlet channel 212 and the recovery channel 213 are all connected to the storage cavity 210. Among them, the end of the first delivery pipeline 13 away from the screw pump 121 is connected to the oil inlet channel 211.

[0069] The storage element 20 is provided with a liquid level monitoring element 24 for monitoring the liquid level of the grease in the storage element 20. The liquid level monitoring element 24 is a liquid level meter or a liquid level sensor, and is installed on the bottom end surface of the cover plate 22 or the inner circumference of the main body 21.

[0070] Furthermore, the automatic coating device 100 further includes an alarm 80, which is located outside the storage element 20. The control device 60 is connected to the alarm 80 and the liquid level monitoring element 24 by signal, and is used to control the alarm 80 to emit a sound signal or a light signal to alarm after the liquid level monitoring element 24 detects that the liquid level of the grease in the storage element 20 exceeds a preset value, so as to remind the operator to stop injecting grease into the storage element 20. Alternatively, the control device 60 controls the liposuction device 12 to stop working after detecting that the liquid level of the grease in the storage element 20 exceeds a preset value.

[0071] Please combine again Figure 1 to Figure 2 In one embodiment, the automatic coating equipment 100 also includes a conveying component 40, one end of the conveying component 40 is connected to the storage chamber 210 of the storage component 20, and the other end of the conveying component 40 is connected to the grease coating component 30, which is used to transport the grease in the storage component 20 to the grease coating component 30.

[0072] Specifically, the delivery assembly 40 includes a delivery pump 41 and a second delivery pipe 42. One end of the delivery pump 41 is connected to the oil outlet channel 212, and the other end thereof is connected to one end of the second delivery pipe 42. One end of the second delivery pipe 42 away from the delivery pump 41 is connected to the oil inlet of the grease coating assembly 30, so that the grease is delivered to the grease coating assembly 30 through the delivery pump 41.

[0073] Furthermore, the automatic coating device 100 further includes a recovery pipe 50. One end of the recovery pipe 50 is connected to the oil outlet of the grease coating assembly 30, and the other end of the recovery pipe 50 is connected to the recovery channel 213, and is used to recover the grease remaining in the grease coating assembly 30 to the storage unit 20. In this way, when the grease is coated on the optical fiber surface, part of the grease drips from the optical fiber surface and accumulates in the grease coating assembly 30, resulting in an error in calculating the weight of the grease coated on the optical fiber surface according to the change in the weight of the grease in the storage unit 20.

[0074] In particular, the liquid level of the grease in the storage element 20 should always be lower than the height of the recovery channel 213 to avoid affecting the recovery of the grease.

[0075] Please combine again Figure 1 to Figure 2 In one embodiment, the control device 60 is connected to the delivery component 40 by signal, and is used to adjust the delivery flow rate of the delivery component 40 according to the amount of grease applied per unit length of the optical fiber.

[0076] Specifically, the control device 60 is preset with a standard grease amount, and the control device 60 is used to compare the obtained grease amount per unit length of the optical fiber with the standard grease amount. If the obtained grease amount per unit length of the optical fiber is greater than the standard grease amount, the control device 60 controls the delivery component 40 to reduce the grease delivery flow rate. If the obtained grease amount per unit length of the optical fiber is less than the standard grease amount, the control device 60 controls the delivery component 40 to increase the grease delivery flow rate, thereby ensuring the uniformity of the grease coated on the optical fiber and avoiding excessive grease on the optical fiber.

[0077] Furthermore, the control device 60 includes a communication module 61 , a storage module 63 , and an analysis module 62 .

[0078] The communication module 61 is connected to the traction assembly 70 and the weighing device 23 by signal, and obtains the traction speed of the optical fiber during the monitoring time and the weight difference of the grease in the storage unit 20 during the monitoring time. The analysis module 62 is electrically connected to the communication module 61, and is used to calculate the amount of grease applied per unit length of the optical fiber after receiving the traction speed and the weight difference. The storage module 63 stores the standard amount of grease applied, and the analysis module 62 is electrically connected to the storage module 63, and is used to obtain the standard amount of grease applied, and to calculate the difference between the standard amount of grease applied and the amount of grease applied per unit length of the optical fiber, and then judge whether the current amount of grease applied is more or less, and feed back the judgment result to the communication module 61. The communication module 61 is also connected to the delivery pump 41 by signal, so as to control the delivery pump 41 according to the judgment result to adjust the size of its delivery flow.

[0079] At the same time, the communication module 61 is also connected with the liposuction device 12, the alarm 80 and the liquid level monitoring component 24. The communication module 61 receives the signal detected by the liquid level monitoring component 24 and transmits it to the analysis module 62. The storage module 63 also stores the standard liquid level. The analysis module 62 compares the received current grease height with the standard liquid level and determines whether the grease in the storage component 20 exceeds the threshold. If it exceeds the threshold, the control signal is transmitted to the liposuction device 12 and the alarm 80 through the communication module 61, thereby controlling the liposuction device 12 to stop working and controlling the alarm 80 to alarm.

[0080] In the above, the specific embodiments of the present application are described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various changes and substitutions may be made to the specific embodiments of the present application without departing from the scope of the present application. These changes and substitutions are all within the scope defined by the present application.
