Description

TECHNICAL FIELD

[0001] The utility model relates to chip processing (including but not limited to capillary tail fiber, FA tail fiber, connector tail fiber, receptacle tail fiber) field, especially to a kind of adjustable automatic hot stripping machine high-precision stripping clamp. BACKGROUND

[0002] With the rise of AI large model, a large number of high-speed optical module demand surges. High-speed optical modules such as 100G, 400G, 800G and other products are designed to ensure long-term mechanical reliability, and the fiber length tolerance of internal MUX or DEMUX passive components is becoming more and more stringent, gradually upgrading from L±0.6mm to L±0.3mm. High-precision fiber length tolerance makes the internal MUX or DEMUX passive components of the optical module have smaller bending radius and smaller stress characteristics, which undoubtedly brings better mechanical strength reliability, greatly improves the stability of MUX or DEMUX passive components in the optical module, and thus improves product quality. Therefore, it is imperative to improve the fiber length tolerance of MUX or DEMUX passive components in the optical module.

[0003] The existing fiber stripping length control technology mainly has two kinds, the first kind is fiber stripping pliers cold stripping, which marks the size mark on the optical fiber alone and then strips the fiber, or installs a fixed length limiting device on the stripping pliers; the second kind is automatic hot stripping machine marking stripping, which marks a specified scale line behind the stripping blade position of the hot stripping machine, and then strips the fiber after aligning the scale line for each product.

[0004] The fiber stripping pliers cold stripping often marks the size mark on the optical fiber alone and then strips the fiber, or installs a fixed length limiting device on the stripping pliers, both of which have low efficiency and low controllable precision, high fault tolerance, large personnel error, and the batch fiber length tolerance can only be controlled within L±0.6mm, which does not meet the fiber length tolerance requirements of internal MUX / DEMUX passive components of some high-speed optical modules. This fiber stripping method is more likely to cause optical loss at the fiber stripping port, thereby affecting the product parameters or reliability with a certain probability.

[0005] The automatic hot stripping machine marking stripping often marks a specified scale line behind the stripping blade position of the hot stripping machine, and then strips the fiber after aligning the scale line for each product. This method is an indirect control of fiber length, which requires cutting the fiber to a high precision length first, and then stripping the fiber with a certain precision tolerance. This method has low efficiency, and the batch fiber length precision tolerance can only be controlled within L±0.5mm. Both of the two fiber stripping methods cannot meet the tolerance requirement of L±0.3mm for batch fiber stripping length. SUMMARY

[0006] To solve the above problems, the technical scheme provides a high-precision stripping clamp of an adjustable automatic thermal stripping machine.

[0007] To achieve the above object, the technical scheme is as follows:

[0008] A high-precision stripping clamp of an adjustable automatic thermal stripping machine, comprising a clamp base, a scale part is arranged on one side of the upper end of the clamp base, a locking part is arranged on the other side of the upper end of the clamp base opposite to the scale part, a containing groove for containing a chip is arranged between the scale part and the locking part, a plurality of locking screws are arranged in the horizontal direction of the locking part, and a limiting block capable of cooperating with any one of the locking screws is further arranged in the containing groove.

[0009] In some embodiments, a positioning hole is further arranged on the clamp base.

[0010] In some embodiments, the locking screw is a hexagonal screw or a cross screw.

[0011] In some embodiments, the inner surface of the containing groove is smooth.

[0012] The application has the following beneficial effects:

[0013] The application focuses on solving the problem of low fiber length control precision in the traditional process, and the purpose of the utility model is to control the fiber length precisely, so that the fiber length tolerance of the batch production of MUX / DEMUX passive components and the like is controlled within L±0.3mm (including but not limited to various types of accurate fiber stripping, capillary tube fiber accurate stripping, FA fiber accurate stripping, connector fiber accurate stripping, receptacle fiber accurate stripping). The clamp realizes one-step fiber length control, and does not need to control the fiber length and then control the fiber stripping length, but only needs to control the fiber length roughly and then control the fiber stripping length accurately, so that the efficiency of the two steps can be greatly improved. BRIEF DESCRIPTION OF DRAWINGS

[0014] In order to more clearly illustrate the technical solutions in the embodiments of the utility model, the following will briefly introduce the drawings needed to be used in the embodiment description.

[0015] Figure 1 is a structural schematic diagram of the embodiment of the utility model. DETAILED DESCRIPTION

[0016] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear and obvious, the following will further illustrate the utility model in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0017] Please refer toFigure 1 As shown, the adjustable automatic heat stripping machine high-precision fiber stripping clamp comprises a clamp base 1, a scale part 2 is arranged on one side of the upper end of the clamp base 1, a locking part 3 is arranged on the other side of the upper end of the clamp base 1 opposite to the scale part 2, a containing groove for containing a chip is arranged between the scale part 2 and the locking part 3, a plurality of locking screws 4 are arranged in the horizontal direction of the locking part 3, and a limiting block 5 capable of cooperating with any one of the locking screws 4 is further arranged in the containing groove.

[0018] In operation, the limiting block is moved to a suitable position which can be fed back from the scale, then the corresponding screw is locked, thereby forming a containing groove of a specific size, and then the chip is placed in, so that the fixed-length stripping purpose is achieved. The containing groove is designed with different sizes according to different products, so that the product can be accurately placed in the groove, and the stripping is more accurate.

[0019] The scale part is a laser-marked scale, which is accurate to 0.1 mm, and can facilitate repeated and rapid adjustment of the clamp for different specifications. When a specified specification is re-produced each time, only the adjustable limiting block of the clamp needs to be adjusted under a microscope, aligned with the corresponding scale, and then the clamp locking screw is locked to achieve accurate control of the length of the stripped fiber tail and realize the length-adjustable and size-accurate stripping.

[0020] In the embodiment, the clamp base 1 is further provided with a positioning hole 6, which can be accurately installed on the automatic heat stripping machine. Different sizes of heat stripping machines can be appropriately adjusted according to the corresponding installation size design, and the scheme can be adapted to various automatic heat stripping machines.

[0021] In the embodiment, the locking screw 4 is a hexagonal screw or a cross screw. The screw can be an internal hexagonal screw or other screw that is easy to adjust and has a relatively conventional adjusting tool. The front surface of the screw is flat, and the front end surface of the screw can contact the side surface of the adjustable limiting block of the clamp after being slightly twisted, so as to achieve the purpose of fixing the adjustable limiting block of the clamp, and finally make the stripping length stable and reliable.

[0022] In the embodiment, the inner surface of the containing groove is smooth, and the front end contacts the end surface of the product capillary / FA / insert core, so that the end surface will not be damaged.

[0023] The general fixture is designed based on the automatic hot stripping machine commonly used in the market, can be directly loaded on the automatic hot stripping machine to realize high-precision fiber stripping and accurately control the fiber length tolerance; the designed fixture can be adjusted and the size can be observed, so that various specifications of internal passive components MUX / DEMUX products of optical modules (including but not limited to various types of accurate fiber stripping, capillary fiber accurate fiber stripping, FA fiber accurate fiber stripping, connector fiber accurate fiber stripping, receptacle fiber accurate fiber stripping) can be made by the same fixture, which has strong universality and flexibility. When mass production, data can be realized to the operation instruction book or product specification book, which is convenient for repeated production of uniform specifications and can directly adjust the corresponding size to produce fiber length tolerance L±0.3mm products.

[0024] The application has the following beneficial effects:

[0025] The fiber length control precision is very high: when mass production, the product length L±0.3mm can be realized by the fixture, which can meet the current mainstream high fiber length requirement of optical module internal MUX / DEMUX passive component fiber length requirement. According to the high-precision sample production, even the highest control can be within L±0.15mm.

[0026] Operation is foolproof and fault tolerance is low: compared with the traditional fiber cutting and stripping which need to accurately control the length, the fixture realizes higher precision fiber length tolerance control through one-step stripping. When stripping, the product only needs to be pushed to the limiting block in the width limiting groove and then pressed to realize stripping, which is very simple to operate and has very short training period, and the fiber length error rate is almost zero.

[0027] High efficiency: other technologies generally need to control the length of fiber cutting and stripping, this fixture can realize rough cutting without accurate cutting, and the rough cutting efficiency is expected to be more than 1 times higher than the accurate cutting efficiency. The stripping efficiency is more than 1 times faster than the cold stripping manual alignment and ensuring the hand to hold after stripping, and the stripping efficiency is comparable to other hot stripping (but the cutting efficiency of the front-end process is also improved very obviously).

[0028] The above only describes the preferred embodiments of the application, and is not intended to limit the scope of the application, other principles and basic structures similar to the application are within the scope of the application.
