Description

Technical Field

[0001] The utility model relates to the technical field of fiber arrangement block production, in particular to a fiber arrangement block mould. Background Art

[0002] Fiber optic array products generally have 2CH / 4CH / 8CH / 12CH channels, and the optical fiber generally uses 250μm coated bare optical fiber. Before assembly, the optical fibers need to be neatly arranged in an array with an accuracy requirement of ±0.02mm, so customized fiber arrangement blocks are needed. However, the fiber arrangement blocks currently used are mostly made by machining and cutting. The processed fiber arrangement blocks have some burrs and sharp corners, and the bare optical fiber coating is made of soft acrylic material, which makes it easy for the fiber arrangement blocks to scratch the optical fiber, causing damage to the optical fiber. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a fiber arrangement block mold, which solves the problem that the fiber arrangement blocks produced in the prior art easily scratch the optical fibers, causing damage to the optical fibers.

The liquid silicone used for molding is injected into each closed casting groove, and then demolded one by one after subsequent curing to complete the processing of the fiber arrangement block. Compared with traditional machining, the direct molding method of the casting groove can make the surface of the fiber arrangement block smoother, thereby reducing the burrs and sharp corners left after traditional machining, and can effectively avoid scratches, indentations and damage on the optical fiber surface, greatly improving the production yield. Moreover, different types of casting grooves can be used to process the corresponding fiber arrangement blocks according to different types of fiber arrangement blocks, which also reduces the cost of manufacturing the fiber arrangement blocks.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 5 As shown, the embodiment of the present invention proposes a fiber arrangement block mold for processing a fiber arrangement block workpiece 9, comprising:

[0027] Base 1;

[0028] The template 2 is provided on the base 1 and has a plurality of pouring grooves 201;

[0029] The pressing plate 3 is provided with two mounting rods 4 on one side of the template 2 close to the pouring groove 201 . The pressing plate 3 is provided on the base 1 and sleeved between the two mounting rods 4 , and abuts against the side of the template 2 to close the pouring grooves 201 .

[0030] In the embodiment of the present utility model, the base 1, the template 2 and the pressing plate 3 are mainly composed of three large parts, and the base 1, the template 2 and the pressing plate 3 are all made of hard stainless steel. Figure 3 and Figure 4 Different types of pouring grooves 201 can be processed according to different models, and the slow wire walking method is used for processing to ensure that the fiber optic groove width in the processed fiber optic block is 0.27±0.01mm, the groove depth is 0.25±0.01mm and the spacing tolerance is ±0.01mm. The pouring groove 201, the base 1, the template 2 and the pressure plate 3 are ground with a grinder to ensure a flatness of 0.005 and a roughness of 0.8 to prevent leakage due to gaps after mold closing.

[0031] Secondly, when processing the fiber row block workpiece 9, the base 1, template 2 and pressing plate 3 are molded together, and the casting groove 201 is closed by the base 1, template 2 and pressing plate 3 to form a mold structure with an open top. Then, the liquid silicone is injected into the casting groove 201 through the glue injection syringe, and the silicone overflowing from the top opening of the casting groove 201 is scraped and leveled with a plastic scraper. After the silicone is naturally cured for 12 hours, the pressing plate 3 is directly pulled out, so that the pressing plate 3 moves on the two mounting rods 4, thereby separating the pressing plate 3 from the formed fiber row block. Finally, the cured fiber row block workpiece 9 is gently removed from the casting groove 201 with tweezers, and the burrs around the fiber row block workpiece 9 are cut off with a cutting knife. The processing is completed quickly. In the subsequent use of the fiber row block workpiece 9, Figure 5 As shown, four 0.25 bare optical fibers cut to length are placed in the fiber arrangement grooves in the fiber arrangement block workpiece 9 to complete the optical fiber positioning operation.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the mounting rod 4 is provided with a first limit block 401, which is sleeved with a first spring 7. The first spring 7 abuts between the first limit block 401 and the pressure plate 3. The first limit block 401 can limit the position of the pressure plate 3 to prevent it from excessive movement or falling off during operation, thereby ensuring the stability of the position of the pressure plate 3. In addition, with the cooperation of the first spring 7, during the production process of the fiber stripping block workpiece 9, the pressure plate 3 is always under the pressure of the first spring 7 and firmly abuts against the template 2, ensuring the production accuracy of the fiber stripping block workpiece 9. Moreover, the first limit block 401 is threadedly connected to the end of the mounting rod 4, making the first limit block 401 and the mounting rod 4 detachable, convenient for replacing and installing the first spring 7.

[0033] Specifically, such as Figure 1 As shown, the pressing plate 3 is provided with two mounting grooves 303 corresponding to the two mounting rods 4, and a clamping block 6 is slidably provided in each of the two mounting grooves 303. The mounting rod 4 is provided with a clamping groove 402. When the pressing plate 3 is separated from the template 2, the clamping block 6 is clamped in the clamping groove 402.

[0034] Since the pressing plate 3 is always under the pressure of the first spring 7 and moves toward the template 2, in order to facilitate the demoulding of the fiber block workpieces 9 one by one, when separating the pressing plate 3 and the template 2, the pressing plate 3 can be moved so that the block 6 on the pressing plate 3 is engaged in the slot 402 of the corresponding mounting rod 4, and the pressing plate 3 is fixed on the mounting rod 4. After all the strips are demoulded and cleaned, the block 6 is directly separated from the slot 402, so that the pressing plate 3 can be abutted against the template 2 again and can be used again later.

[0035] Secondly, if Figure 2 As shown, the pressure plate 3 is penetrated by a connecting rod 5, and the two blocks 6 are both provided with a mounting seat 601, and the connecting rod 5 is connected to the mounting seats 601 of the two blocks 6; the connecting rod 5 can synchronously operate the blocks 6 in the two mounting grooves 303, so that the two blocks 6 move synchronously in the same direction, and the operation is more convenient.

[0036] Moreover, one end of the connecting rod 5 passes through one side of the pressure plate 3 and is provided with a second limit block 501. The one end of the connecting rod 5 that passes through the pressure plate 3 is sleeved with a second spring 8, and the second spring 8 abuts between the pressure plate 3 and the second limit block 501; under the action of the second spring 8, the connecting rod 5 is always subjected to outward pulling force, so that the connecting rod 5 drives the clamping block 6 to always abut against the surface of the mounting rod 4. When the fiber block workpiece 9 is demolded, the pressure plate 3 is directly pulled. When the clamping block 6 is just aligned with the clamping groove 402, the clamping block 6 can be driven to be directly clamped into the clamping groove 402 under the action of the second spring 8 to complete self-locking. After the demolding is completed, the connecting rod 5 is directly pressed so that the clamping block 6 is directly separated from the clamping groove 402, and the pressure plate 3 can be abutted against the template 2 again under the action of the first spring 7.

[0037] Furthermore, if Figure 2 As shown, the second limiting block 501 is threadedly connected to one end of the connecting rod 5, so that the second limiting block 501 and the connecting rod 5 are detachably connected, which facilitates the disassembly and replacement of the second spring 8.

[0038] Specifically, such as Figure 1 As shown, a groove 301 is provided on the top of the pressing plate 3, and a protrusion 302 is provided on the outer side of the pressing plate 3 to protrude from the groove 301; the design of the protrusion 302 and the groove 301 allows the operator to grasp the pressing plate 3 more easily, provides a better gripping point, and makes operation easier.

[0039] like Figure 1 As shown, the template 2 is provided with a mounting hole 202, and the base 1 is penetrated by a bolt, which is threadedly connected to the mounting hole 202; the threaded connection between the bolt and the mounting hole 202 can ensure that the template 2 is firmly fixed on the base 1, providing stable support and preventing the template 2 from being displaced during the processing. Moreover, the bolt connection method allows the template 2 to be easily removed from the base 1, which is convenient for replacing the template 2 or performing cleaning and maintenance work.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
