Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber processing equipment, in particular to an integrated equipment for stripping optical fiber coating and cutting optical fiber. Background Art

[0002] In optical fiber communication and related fields, the requirements for optical fiber processing are getting higher and higher. The traditional optical fiber coating stripping and cutting methods have problems such as low efficiency, poor precision, and easy damage to the optical fiber.

[0003] For example, in existing high-power fiber lasers, the fiber coating is mostly stripped by cutting with a manual blade before stripping. On the one hand, there is improper force control in pure manual stripping, which causes the blade to hit the fiber core and damage the fiber core. On the other hand, due to the lack of corresponding clamps, it is difficult to strip the coating when stripping the fiber coating. The movement of the fiber is a straight line. Once the trajectory of the fiber movement deviates, the stripped opening becomes tilted, affecting subsequent use. Therefore, an integrated device for stripping and cutting optical fiber coating is proposed to solve the above defects.

[0052] It should be noted that: the outside of the optical fiber component 101 is clamped by the clamp unit 1 and the steering assembly 22 respectively, the clamp unit 1 is pulled to straighten the optical fiber component 101, and then the laser unit 3 is used to irradiate the laser to the outside of the optical fiber component 101 between the clamp unit 1 and the steering assembly 22.

Subsequently, the clamp unit 1 is released to reset the optical fiber component 101, and after the steering assembly 22 is rotated 180°, the steering assembly 22 is brought The optical fiber component 101 is rotated 180°, so that the coating layer of the optical fiber component 101 originally in the backlight area is ablated after switching to face the laser.

[0062] A sleeve 211 is fixedly connected to the upper end of the base plate 100 and away from the fixture unit 1, and the axis of the sleeve 211 is coaxial with the axis of the first receiving hole 131;

[0063] A fixed baffle 212, fixedly connected to one end of the sleeve 211 located at the clamp unit 1;

[0064] The sliding baffle 213 is slidably inserted into the sleeve 211, and the interior of the fixed baffle 212 and the interior of the sliding baffle 213 are both provided with a hole for penetrating the optical fiber member 101;

[0065] A tension spring 214 is sleeved on the outside of the optical fiber component 101 and is located between the fixed baffle 212 and the sliding baffle 213, and is used to tighten the optical fiber component 101;

[0066] One end of the tension spring 214 is fixedly connected to the fixed baffle 212 .

[0067] Further, such as Figure 2 , Figure 4 As shown, the steering assembly 22 includes:

[0068] The fixing frame 221 is provided with two groups, and is respectively fixedly connected to one side of the sliding baffle 213, and the optical fiber component 101 is located between the two groups of the fixing frames 221, and a second threaded hole 2211 is provided inside the fixing frame 221;

[0069] A second threaded rod 222, threadedly connected inside the second threaded hole 2211, one end of the second threaded rod 222 is fixedly connected to a second rotating rod 2221 for rotating and adjusting the second threaded rod 222;

[0070] The clamping plate 223 is rotatably disposed on one end of the second threaded rod 222 opposite to the second rotating rod 2221 , and is used to cooperate with the pressing block 15 to clamp the optical fiber component 101 .

[0071] Furthermore, one end of the second threaded rod 222 relative to the second rotating rod 2221 is fixedly connected with a second limiting block 2222;

[0072] A second limiting groove 2231 for accommodating and limiting the second limiting block 2222 is provided inside the clamping plate 223 and outside the second limiting block 2222;

[0073] Arc-shaped grooves for accommodating the optical fiber component 101 are provided at the positions corresponding to the outer sides of the two groups of clamping plates 223 and the optical fiber component 101 .

[0074] Among them, Figure 7 As shown, the laser unit 3 includes:

[0075] The CCD lens 31 is disposed between the clamp unit 1 and the tensioning assembly 21 and is located directly above the optical fiber component 101, and is used to observe the cutting and stripping locations of the optical fiber component 101;

[0076] The condenser 33 and the reflector 32 are sequentially located on one side of the optical fiber 101 and are used to reflect the laser light and focus it on the outer side of the coating layer of the optical fiber 101;

[0077] The laser 34 is disposed on the upper end of the reflector 32 and is used to provide a light source for the reflector 32 .

[0078] It should be noted that: in the specific implementation process of the present invention, Figure 1-6 As shown, the optical fiber component 101 is passed through the tension spring 214, the fixed baffle 212, and the first accommodating hole 131 in sequence, and the first rotating rod 141 is rotated. The first rotating rod 141 drives the first threaded rod 14 to rotate. The first threaded rod 14 drives the pressing block 15 to move downward under the action of the thread tangential force between the first threaded hole 132, so that the optical fiber component 101 is pressed. Then the second rotating rod 2221 is rotated. The second rotating rod 2221 drives the second threaded rod 222 to rotate. The second threaded rod 222 drives the second threaded rod 222 to rotate by cooperating with the second threaded hole 2211. The clamping plate 223 clamps the optical fiber component 101, and then pushes the plug 13 along the guide groove 12, and the plug 13 drives the optical fiber component 101 in the compressed state to be gradually straightened. In this process, the optical fiber component 101 drives the second threaded rod 222 to move through the clamping plate 223, and the second threaded rod 222 drives the sliding baffle 213 to move along the sleeve 211 through the fixing frame 221, so that the tension spring 214 is gradually compressed. Under the elastic force of the tension spring 214, the optical fiber component 101 is always in a straightened state, reducing the error of subsequent laser stripping;

[0079] like Figure 2-3 , Figure 8 As shown, then, the laser 34 is turned on, and the laser 34 integrates the laser through the reflector 32 and reflects it to the condenser 33, and under the focusing effect of the condenser 33, it is emitted to the coating layer of the optical fiber 101, so that the coating layer of the optical fiber 101 is ablated, and the plug 13 is further pushed along the guide groove 12, and the plug 13 drives the optical fiber 101 forward, so that the ablated coating layer is from line to surface, and the forward movement of the plug 13 is guided by the guide groove 12, so that the forward trajectory of the optical fiber 101 driven by the plug 13 is a straight line, so as to avoid the deviation of the forward trajectory of the optical fiber 101 and cause the opening after stripping to be tilted, and further reduce the stripping error;

[0080] like Figure 1-3 , Figure 7 As shown, in addition, after the coating layer in the laser irradiation area is ablated, the fixing frame 221 is released. At this time, the tension spring 214 moves the fixing frame 221 through the sliding baffle 213, and the fixing frame 221 drives the optical fiber component 101 to reset through the clamping plate 223. Subsequently, the optical fiber component 101 is rotated 180° around the axis of the optical fiber component 101. The fixing frame 221 drives the optical fiber component 101 to rotate 180° through the clamping plate 223, so that the coating layer in the original backlight area that has not been ablated is ablated by laser irradiation, and then during the ablation process, the plug 13 is gradually pulled along the guide groove 12, so that the backlight area where the ablation work has been completed corresponds to the position of the ablation area of ​​the light area, thereby completing the stripping work of the optical fiber component 101. No cutting work is required in the entire process, thereby avoiding scratches on the core of the optical fiber component 101.
