Description

Technical Field

[0001] This utility model relates to the technical field of power component testing equipment, specifically to an end face testing device for MPO type products. Background Technology

[0002] Currently, in the production process of MPO products, some MPO products with broken or cracked fibers inevitably occur. Broken fiber MPO products can be identified during polarity testing and routine end-face inspection; however, broken fiber MPO products, especially those with slight breaks, cannot be effectively identified through polarity testing and routine end-face inspection. These defective products severely impact customer use, so the industry typically uses precision instruments such as optical time-domain reflectometers to identify them through performance testing. However, this approach has the following drawbacks: 1. Low efficiency: It usually takes 40 seconds to test a dual-head product, and even longer for multi-head branch products; 2. Prone to secondary defects: During performance testing, the light output ferrule of the precision instrument needs to be in close physical contact with the light input ferrule of the line under test of the MPO product. Therefore, it is very easy for the light input ferrule of the line under test of the MPO product to be damaged by impact and cross-contamination by dirt. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an end face inspection device for MPO products, so as to solve the problems of low efficiency and easy secondary defects in the fiber breakage detection of MPO products in the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an end-face inspection device for MPO-type products, comprising: A light-transmitting mechanism, wherein the light-transmitting mechanism has at least one light-transmitting component, each light-transmitting component having an assembly port through which one end of an MPO-type product passes and fits, and a coaxial light source arranged coaxially with the assembly port; An end-face inspection instrument is placed at the other end of an MPO product to capture images of the inspection end face of the MPO product, compare and output the inspection results.

[0005] Compared with the prior art, the present invention has the following beneficial effects: 1. This MPO product end face inspection device operates relatively quickly when inspecting MPO products, and on average, one MPO product can be inspected within 6-15 seconds. 2. When this MPO product end face inspection device inspects MPO products, one end of the MPO product passes through the assembly port and faces the coaxial light source. The end face inspection instrument is placed at one end of the MPO product. The coaxial light source provides a stable and good light input environment. The end face inspection image the inspection end face of the MPO product and compares the results to output the inspection results. During this process, the end face of the MPO product does not come into contact with the coaxial light source, so it will not cause secondary defects. Attached Figure Description

Detailed Implementation

[0008] The present invention will be further described in detail below through specific embodiments: like Figure 1 , Figure 2 as well as Figure 3 As shown in the figure, this utility model embodiment proposes an end face inspection device for MPO type products, including a light transmission mechanism 1 and an end face inspection instrument. The light transmission mechanism 1 has at least one light transmission component, each light transmission component has an assembly port 11 through which one end of the MPO type product passes and is adapted, and a coaxial light source 12 arranged coaxially with the assembly port 11. The end face inspection instrument (not shown in the figure) is arranged at the other end of the MPO type product to capture the inspection end face of the MPO type product for imaging and comparison to output the inspection result.

[0009] When inspecting MPO products: one end of the MPO product passes through the assembly port 11 and faces the coaxial light source 12, and the end face inspection instrument is placed at one end of the MPO product. The coaxial light source 12 provides a stable and good light input environment. The end face inspection instrument images the inspection end face of the MPO product and compares the results to output the inspection results. During this process, the end face of the MPO product does not come into contact with the coaxial light source 12, so no secondary defects will be caused.

[0010] In practice, the detection efficiency is as follows: on average, an MPO product can be detected within 6-15 seconds, which is relatively faster.

[0011] In this solution, the light transmission mechanism 1 is a structure designed independently according to requirements; the end face inspection instrument is a purchased structure, specifically a 400x dimension end face inspection instrument, and its detection and operation principle is existing technology, which will not be further explained here.

[0012] To better understand this solution, the light transmission mechanism 1 will be described in further detail below.

[0013] like Figure 1 , Figure 2 as well as Figure 3 As shown, according to another embodiment of the present invention, the MPO product end face inspection device further includes a housing 13 in the light transmission mechanism 1. The housing 13 has an installation cavity. Each coaxial light source 12 is connected to a light source fixing block 14 disposed in the installation cavity. The assembly ports 11 are all opened on the side walls of the housing 13 and the light-emitting side of the coaxial light source 12 facing each other.

[0014] In this embodiment, the light source fixing block 14 is an inverted "T" shaped block. The light source fixing block 14 is connected to the housing 13 by screws. The light source fixing block 14 provides a certain installation height for the coaxial light source 12, ensuring that the coaxial light source 12 is arranged coaxially with the corresponding assembly port 11. When the coaxial light source 12 is lit, it produces sufficient brightness on the detection end face of the MPO type product, improving the imaging quality of the end face detector and ensuring detection accuracy.

[0015] Based on the above solution: The housing 13 includes a bottom plate 131, a top plate 132 arranged opposite to the bottom plate 131, a front plate 133, a power supply mounting plate 134, and two side plates 135 connected between the bottom plate 131 and the top plate 132. At least one support column 136 connected to the power supply mounting plate 134 is connected between the bottom plate 131 and the top plate 132. The front plate 133 and the power supply mounting plate 134 are arranged opposite to each other, and the two side plates 135 are arranged opposite to each other. An assembly port 11 is opened on the front plate 133, and the light source fixing block 14 is connected to the bottom plate 131.

[0016] Here, the base plate 131, top plate 132, front plate 133, power supply mounting plate 134, and side plates 135 cooperate to form a square housing 13, providing space for the installation of the coaxial light source 12 and an independent environment for its operation. Two support columns 136 are provided to ensure sufficient structural stability of the housing 13. A power supply connected to the coaxial light source 12 can be installed on the power supply mounting plate 134 to provide power for its illumination. The coaxial light source 12 can also be equipped with a switch for convenient control of its on / off state.

[0017] To improve the assembly stability of MPO products in the assembly port 11 and ensure that the MPO products are coaxially arranged with the corresponding coaxial light source 12, a product detection plate 15 is connected to the inner side wall of the housing 13 where the assembly port 11 is located. The assembly port 11 extends through the product detection plate 15. Specifically, the product detection plate 15 is fixedly attached to the inner wall of the front plate 133 to extend the length of the assembly port 11 and improve the assembly stability of the MPO products.

[0018] Furthermore, each of the assembly ports 11 is fitted with a housing baffle 16 connected to the outer wall of the housing 13, with the assembly port 11 extending through the corresponding housing baffle 16. Specifically, the housing baffle 16 is fixedly attached to the outer wall of the front panel 133, extending the length of the assembly port 11 and guiding the MPO product during the assembly process, so that the MPO product can be quickly and stably assembled and then cooperate with the corresponding coaxial light source 12.

[0019] To improve the assembly stability of MPO products, the outer wall of the housing 13 is rotatably connected to an assembly port 11, each of which has a clearance notch 171 formed on the pressure plate 17. Rotating the pressure plate 17 allows one end of the MPO product assembled at the assembly port 11 to pass through the clearance notch 171 and be pressed onto the outer wall of the MPO product. Specifically, one end of the pressure plate 17 is connected to the top plate 132 via a hinge, and the clearance notch 171 is formed on the other end of the pressure plate 17.

[0020] In this embodiment, the number of light-transmitting components is specifically two, and the coaxial light source 12 is an LED coaxial light source 12.

[0021] The end-face inspection device for this type of MPO product is used as follows: Use a lux meter to adjust the illuminance of the two coaxial LED light sources 12 to equal values, with the specific application value in the range of 100~120 lux; MPO products were then assembled at both assembly ports 11. Next, rotate the pressure plate 17, and the two MPO products pass through the corresponding notches. The pressure plate 17 presses against the outer wall of the two MPO products to ensure that the two MPO products and the corresponding coaxial light source 12 remain stably coaxial, preventing misjudgment and unclear vision due to insufficient light input caused by skewness. Finally, the end faces of the two MPO products are imaged and compared to output the test results.

[0022] This MPO product end-face inspection device utilizes the adjustability and stability of the LED coaxial light source 12 to provide an excellent light input environment. Through extensive experimentation, a feasible illuminance value was determined. Combined with the end-face inspection instrument, it achieves the purpose of quickly and effectively identifying fiber cracks.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
