[0002] Optical fiber is a light transmission tool that uses the total reflection principle of light in a fiber made of glass or plastic. It is widely used in the field of communications. During the construction and maintenance of optical fiber laying, it is often necessary to perform a fusion splicing operation on the optical fiber. Before the fusion splicing operation, the optical fiber needs to be cut and the coating stripped.

[0003] At present, there is a thermal stripping machine on the market that can strip the coating of the optical fiber. The existing thermal stripping machine includes a heating base and a blade. The heating base can heat and soften the coating of the optical fiber, and the blade can cut the softened coating. By softening the coating, the damage to the internal fiber core is reduced during stripping. However, after the current thermal stripping machine strips the coating, the coating will remain on the heating base, and the coating on the heating base needs to be manually cleaned, which affects the efficiency. Due to the heat of the heating base, it is also easy to burn the hands of the staff, which poses certain safety hazards. Utility Model Content

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the utility model.

[0025] Embodiment 1

[0026] like Figure 1-6 As shown, this embodiment discloses an optical fiber thermal stripping device, including a mounting base 1 with a temperature control device 2, a thermal stripping mold 3 connected to the temperature control device 2 is arranged on the mounting base 1, and the thermal stripping mold 3 includes a heating base 31 and a pressure cover 32, and the pressure cover 32 and the heating base 31 are both provided with an extrusion surface 33 and a cutting component 34 perpendicular to the extrusion surface 33, and the pressure cover 32 and the heating component are mutually attached through two extrusion surfaces 33 for clamping the optical fiber.

[0027] like Figure 1-4As shown, the pressure cover 32 is rotatably connected to one side of the heating base 31 through a rotating shaft 7, and the pressure cover 32 can be rotated relative to one side of the heating base 31 through the rotating shaft 7 to realize the opening and closing of the hot stripping mold 3; and, anti-skid patterns 8 and a plurality of positioning grooves 9 for placing optical fibers are convexly provided on the two extrusion surfaces 33, and the positioning grooves 9 are provided in the anti-skid patterns 8, and the positioning grooves 9 pass through the surface of the extrusion surface 33; and the cutting assembly 34 is provided on one side of the pressure cover 32 and the heating base 31 relative to the rotating shaft 7, and the cutting assembly 34 includes a knife groove 341 provided on one side of the heating base 31 or the pressure cover 32, and a blade 342 is fixedly provided in the knife groove 341, and a hole groove 343 matching the shape of the optical fiber is provided on the side where the two blades 342 contact each other, and the hole groove 343 corresponds to the position of the positioning groove 9.

[0028] When it is necessary to cut and soften the coating of the optical fiber, the staff first turns on the switch of the temperature control device 2, and then adjusts the temperature through the knob, allowing the temperature control device 2 to heat the heating base 31 through the connecting line, and then the staff places one end of the optical fiber in the positioning groove 9. The positioning groove 9 set on the pressure cover 32 and the extrusion surface 33 of the heating base 31 can ensure that the hole groove 343 on the blade 342 corresponds to the position of the optical fiber, thereby avoiding damage to the fiber core when the upper and lower blades 342 cut the coating of the optical fiber.

[0029] After placing the optical fiber in the positioning groove 9, the staff controls the pressure cover 32 to flip toward the heating base 31 through the handle 11, so that the extrusion surface 33 of the pressure cover 32 fits with the extrusion surface 33 of the heating base 31 to achieve clamping and heating of the optical fiber. At the same time, the blades 342 on the end faces of the heating base 31 and the pressure cover 32 cooperate with each other to cut the coating. After that, the staff can pull the optical fiber to peel off the coating from the core. The anti-slip grooves 8 raised on the two extrusion surfaces 33 and located on the side of the positioning groove 9 can increase the friction of the extrusion surface 33 on the optical fiber coating, making it easier for the staff to peel off the coating.

[0030] like Figure 1-3As shown, on the basis of the above structure, the present application further provides an air blowing pipe 35 on the mounting base 1, the air outlet end of the air blowing pipe 35 faces the extrusion surface 33 on the heating base 31, and the other end is connected to an air source 36, and the air source 36 is connected to a control component 37, and the control component 37 is used to control the air source 36 to blow air toward the extrusion surface 33 of the heating base 31 through the air blowing pipe 35 after the two extrusion surfaces 33 are separated from each other; wherein, the air source 36 can be an air pump or an air tank connected to a solenoid valve; and the control component 37 includes a PLC control panel 371 and a proximity switch 372 arranged on the mounting base 1, the proximity switch 372 is electrically connected to the air source 36 through the PLC control panel 371, and the sensing end of the proximity switch 372 is located on the moving path when the pressure cover 32 is away from the heating base 31.

[0031] During operation, the air pump or solenoid valve is connected to the PLC control panel 371. When the worker opens the gland 32 through the handle 11, the gland 32 is made of metal and will trigger the proximity switch 372 when passing the proximity switch 372, so that the proximity switch 372 sends a signal to the PLC control panel 371 to control the opening of the solenoid valve on the air pump or gas tank, so that the gas is blown to the extrusion surface 33 on the heating base 31 through the blowing pipe 35, thereby cleaning the coating layer remaining on the extrusion surface 33. This makes it convenient for the worker to directly process the optical fiber next time without cleaning the extrusion surface 33, which improves efficiency and reduces the probability of the worker accidentally touching the extrusion surface 33, reducing safety hazards.

[0032] And, if Figure 2 As shown, the mounting seat 1 is provided with a waste box 4 with an opening on the top, the heating base 31 is arranged at the opening of the waste box 4 and a discharge gap 5 is formed between the heating base 31 and the inner wall of the waste box 4, and a discharge port 43 connected to the inside of the waste box 4 is opened in the middle of the heating base 31; and a baffle 6 is provided on the side of the waste box 4 away from the blowing pipe 35, and the baffle 6 is located on one side of the heating base 31 and is higher than the extrusion surface 33 of the heating base 31.

[0033] The baffle 6 can prevent the coating layer from entering the discharge gap 5 or the discharge port 43, so that it can be collected by the waste box 4, which facilitates unified collection and cleaning, and avoids the flying coating layer from affecting the environment.

[0034] When it is necessary to clean the garbage in the waste box 4 , the staff can directly disassemble the heating base 31 or directly dump the garbage at the bottom through the discharge port 43 .

[0035] A heat insulating pad 10 is also provided on the surface of the pressure cover 32 , and the heat insulating pad 10 can prevent the heat of the pressure cover 32 from being transferred to the handle 11 and causing burns to the hands of the staff.

[0036] Embodiment 2

[0037] like Figure 5 As shown, on the basis of Example 1, a cleaning port 41 is opened on one side of the waste box 4, and a storage hopper 42 is slidably arranged in the cleaning port 41, and the storage hopper 42 is located at the bottom of the waste box 4; by sliding the storage hopper 42 on one side of the waste box 4, the cleaned coating layer can directly fall into the storage hopper 42, and then by opening the storage hopper 42, the garbage can be cleaned conveniently, making cleaning more convenient.

[0038] The mounting base 1 is also provided with an air blowing pipe 35, the air outlet end of the air blowing pipe 35 faces the extrusion surface 33 on the heating base 31, and the other end is connected to an air source 36, and the air source 36 is connected to a control component 37. The control component 37 is used to control the air source 36 to blow air toward the extrusion surface 33 of the heating base 31 through the air blowing pipe 35 after the two extrusion surfaces 33 are separated from each other.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
