Description
Technical Field
[0001] The present invention relates to the technical field of optical fiber detection equipment, and specifically, to an end-face detection device for a pigtail fiber. Background Art
[0002] Since an optical fiber is too thin and prone to brittle fracture, a capillary tube is required to fix the optical fiber to make a pigtail fiber for subsequent grinding of the end face of the optical fiber and subsequent mating and fixing with other glass devices (such as lenses). As Figure 1 shown, a common pigtail fiber for setting an optical fiber includes an optical fiber 1 and a micro capillary tube 2, and the optical fiber 1 is inserted into the capillary tube 2.
[0003] After the pigtail fiber is made and the end face 11 of the pigtail fiber is ground, it is necessary to detect the end face 11 of the pigtail fiber to detect the parallelism between the optical fiber cat-eye connection line and the grinding step of the pigtail fiber and to check whether the grinding step of the pigtail fiber exceeds the standard specifications. The existing end-face detection devices usually use a round-hole fixing member to fix the pigtail fiber. The pigtail fiber needs to be inserted through the round hole and then fixed. When the pigtail fiber is inserted, it is very easy to touch the capillary tube, resulting in end-face chipping and scratches caused by collision, reducing the product qualification rate and the clamping efficiency. Therefore, it is necessary to develop a better detection device. Summary of the Invention
[0004] The main object of the present invention is to provide an end-face detection device for a pigtail fiber with a simple structure, which can improve the clamping efficiency and detection efficiency of the pigtail fiber.
[0005] To achieve the above object, the end-face detection device for a pigtail fiber provided by the present invention includes a display screen, an end-face detector, a three-dimensional adjustment platform, a bearing bottom plate, a bearing cover plate and a pigtail fiber clamping rod. The display screen is electrically connected to the end-face detector. The bearing bottom plate is installed on the three-dimensional adjustment platform, and the bearing cover plate is detachably covered on the bearing bottom plate. The bearing bottom plate is provided with a first clamping rod groove, and the bearing cover plate is provided with a second clamping rod groove. The first clamping rod groove and the second clamping rod groove cooperate to form a clamping rod through hole for installing the pigtail fiber clamping rod. One end of the pigtail fiber clamping rod is provided with a pigtail fiber fixing table, and the end-face detector is disposed opposite to the pigtail fiber fixing table.
[0006] As can be seen from the above solution, the end-face detection device for a pigtail fiber of the present invention combines the bearing bottom plate, the bearing cover plate and the pigtail fiber clamping rod, with a simple structure and easy installation, improving the clamping efficiency of the pigtail fiber and the detection efficiency. At the same time, under the inspection of the end-face detector, the parallelism between the optical fiber cat-eye connection line and the grinding step of the pigtail fiber can be better detected, and whether the grinding step of the pigtail fiber exceeds the standard specifications can be better inspected. Moreover, the three-dimensional adjustment platform is used to adjust the position of the pigtail fiber clamping rod, improving the adjustment accuracy.
[0007] In a further solution, a first fixing block and a second fixing block are arranged on the pigtail fixing table, and the first fixing block and the second fixing block cooperate to form a pigtail fixing position; a fixing bolt is installed on the first fixing block, a pigtail groove is arranged on the second fixing block, and the screwing direction of the fixing bolt faces the pigtail groove.
[0008] It can be seen that the first fixing block and the second fixing block cooperate to form a pigtail fixing position, and the method of locking with a fixing bolt can improve the convenience of pigtail installation and reduce the situation of chipping or breaking of the pigtail end face due to collision.
[0009] In a further solution, the fixing bolt is a plastic bolt.
[0010] It can be seen that using a plastic bolt for the fixing bolt can reduce the abrasion of the pigtail and improve the product yield.
[0011] In a further solution, the pigtail groove is a V-shaped groove.
[0012] It can be seen that setting the pigtail groove as a V-shaped groove can facilitate the fixing of the pigtail, and at the same time reduce the contact area and facilitate light transmission.
[0013] In a further solution, the first clamping rod groove is a V-shaped groove and the second clamping rod groove is a U-shaped groove; or the first clamping rod groove is a U-shaped groove and the second clamping rod groove is a V-shaped groove.
[0014] It can be seen that one of the first clamping rod groove and the second clamping rod groove is a V-shaped groove and the other is a U-shaped groove, which can use the cooperation of the U-shaped groove and the V-shaped groove to clamp the pigtail clamping rod.
[0015] In a further solution, a tightening sleeve is sleeved on the pigtail clamping rod, and the tightening sleeve is sleeved on the fixing part located in the through hole of the clamping rod.
[0016] It can be seen that by setting the tightening sleeve, the friction between the pigtail clamping rod and the bearing bottom plate and the bearing cover can be increased to avoid the change of the pigtail position.
[0017] In a further solution, the pigtail end face detection device further includes a fixing seat, and both the end face detector and the three-dimensional adjustment platform are installed on the fixing seat.
[0018] It can be seen that by installing the end face detector and the three-dimensional adjustment platform together through the fixing seat, it is convenient for overall movement and improves portability. Brief Description of the Drawings
