Description

Technical Field This utility model relates to the field of LED spectrometer technology, and in particular to an induction fiber optic base for disc feeding in LED spectrometers. Background Technology In existing automated LED semi-finished product sorting operations, the disc feeding mechanism on the sorting machine typically requires the use of optical fibers to detect the material status. However, traditional optical fiber mounting structures usually have holes or grooves in their fiber optic ports.

[0001] In actual production, dust generated during LED beam splitting easily accumulates in these grooves and holes, eventually clogging the sensing fiber optic holes. Once the fiber optic holes are clogged with dust, it can lead to sensor malfunction, system misjudgment, and abnormal material feeding, severely impacting the overall production efficiency of the machine.

[0002] To maintain production, operators have to frequently stop the machine to clean these sensing points, which is not only cumbersome but also greatly increases their workload. Therefore, how to provide a sensing fiber optic base that can structurally prevent dust blockage, reduce cleaning and maintenance, and improve material supply stability and production efficiency is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content The purpose of this utility model is to provide an induction fiber seat for disc feeding in LED spectrometers, which aims to solve the technical problems in the prior art, such as the induction fiber holes being easily blocked by dust due to structural reasons, resulting in abnormal feeding, affecting production efficiency, and requiring frequent cleaning, which increases the workload of operators.

[0003] This utility model is achieved through the following technical solution: An induction fiber optic mount for a feeding disc of an LED spectrometer includes a mounting base. One side of the mounting base is provided with a fixing part that can be fixed to the feeding disc. The bottom of the mounting base is provided with a mounting groove for accommodating optical cables and sealing materials. One side of the mounting base is provided with at least one optical fiber hole communicating with the mounting groove.

[0004] As described above, the sensing fiber optic mount for the feeding disc of an LED spectrometer includes a cable groove formed on one side of the bottom of the mount, which is connected to a sealing groove formed on the bottom of the mount for accommodating optical fibers and sealing material.

[0005] As described above, the sensing fiber holder for the feeding disc of an LED spectrometer has at least one partition in the sealing groove, which allows the sealing groove to have at least two independent slots that each accommodate a single optical fiber.

[0006] As described above, the sensing fiber mount for the feed disk of an LED spectrometer includes a fitting portion adapted to the feed disk, and the fixing portion extends cantilevered from one side of the fitting portion.

[0007] As described above, the sensing fiber optic base for the feeding disc of an LED spectrometer has a waist groove on the fixing part that can cooperate with a fastener.

[0008] As described above, the sensor fiber mount for the feeding disc of an LED spectrometer is further provided with at least one air blowing hole and an air inlet hole, wherein the air blowing hole and the air inlet hole are connected inside the mount to form an air passage.

[0009] As described above, in the sensing fiber optic mount for the feeding disc of an LED spectrometer, the air blowing hole is opened on the same side adjacent to the fiber optic hole and located above the fiber optic hole, and the air inlet is opened on the top surface of the mounting base.

[0010] As described above, the induction fiber optic base for the feeding disc of an LED spectrometer has an air inlet diameter of D and an air blowing hole diameter of d, with the relationship between the two satisfying: 2.9d≤D≤3.2d.

[0011] As described above, the sensing fiber optic mount for the feeding disc of an LED spectrometer has a chamfered edge on one side of the fixing part.

[0012] The induction fiber optic mount for the feed disk of an LED spectrometer, as described above, is made of aluminum alloy.

[0013] Compared with the prior art, the present invention has the following advantages: This invention features a mounting groove at the bottom of the mounting base to accommodate the optical cable and sealing material. During assembly, the sealing material can be used to integrally encapsulate the optical cable and fiber root, creating a flat, groove-free surface on the sensing surface of the mounting base facing the material. This structure fundamentally eliminates structural dead zones where dust can accumulate, effectively preventing dust from clogging the fiber optic holes. Compared to existing technologies, this solution eliminates the need for frequent machine shutdowns for cleaning, significantly reducing the workload of operators, ensuring stable material supply, and significantly improving equipment production efficiency. Attached Figure Description To more clearly illustrate the technical solutions in the embodiments of the utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0014] Figure 1 This is a three-dimensional schematic diagram of this embodiment; Figure 2 This is a bottom view of this embodiment; Figure 3This is a top view of this embodiment; Figure 4 This is a front view of this embodiment; Figure 5 for Figure 4 A cross-sectional view along line AA. Detailed Implementation To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0015] Please see the appendix Figures 1 to 5 This embodiment provides an induction fiber optic mount for the feeding disc of an LED beam splitter. The core of this induction fiber optic mount is a mounting base 1. A fixing part 2 is provided on one side of the mounting base 1. The fixing part 2 is used to reliably fix the entire induction fiber optic mount to the feeding disc (not shown) of the LED beam splitter (not shown) using fasteners such as screws and bolts.

[0016] To install and protect the optical cable, the mounting base 1 has a mounting groove 3 at its bottom. The main function of this mounting groove 3 is to accommodate the main body of the optical cable (not shown) and to fill areas requiring sealing with sealing material, such as epoxy resin sealant or silicone. Furthermore, at least one optical fiber hole 4 is provided on one side of the mounting base 1, the inner end of which communicates with the interior of the mounting groove 3. In actual assembly, the sealing material is filled into the mounting groove 3, completely encapsulating the optical cable and the root of the optical fiber. This structure creates a smooth, groove-free surface on the sensing surface of the mounting base 1 facing the material. This smooth design eliminates structural dead zones where dust can accumulate, effectively preventing the optical fiber hole 4 from becoming clogged with dust.

[0017] This integrated sealed structure not only greatly improves the dustproof performance of the sensing fiber optic mount and ensures long-term stability of the sensing, eliminating frequent downtime for cleaning and significantly improving equipment production efficiency, but also allows the optical fiber (not shown) used for sensing in the optical cable to pass through the sealed mounting groove 3 and extend precisely to the location of the material to be sensed through the fiber optic hole 4.

[0018] Furthermore, as a preferred embodiment, the structure of the mounting groove 3 is further optimized to facilitate the laying of the optical cable and the precise filling of the sealing material. As shown in the figure, the mounting groove 3 includes a cable groove 31 formed on one side of the bottom of the mounting base 1, and a sealing groove 32 connected to the cable groove 31. The cable groove 31 is larger in size and is mainly used to accommodate and guide the main body of the optical cable; while the sealing groove 32 is specifically used to accommodate the precision optical fiber stripped from the end of the optical cable and to fill it with sealing material. This segmented design makes the sealing area more concentrated and controllable, ensuring the sealing effect while saving the amount of sealing material used and improving the efficiency of the sealing operation.

[0019] Based on the structure of the aforementioned sealing groove 32, to further improve the sealing reliability of multiple optical fibers, one or more partitions 321 may be provided in the sealing groove 32. These partitions 321 physically divide the sealing groove 32 into at least two independent slots. When multiple optical fibers need to be installed, each optical fiber can be accommodated in an independent slot. Thus, when filling with sealing material, the partitions 321 ensure that the sealing material can uniformly cover each optical fiber, effectively avoiding the problem of insufficient local sealing caused by multiple optical fibers being paralleled or tightly attached to each other, and significantly improving the reliability of dust and moisture protection.

[0020] Furthermore, as a preferred embodiment, the overall structure of the mounting base 1 can be designed as L-shaped. Specifically, the mounting base 1 includes a fitting portion 5 and a fixing portion 2 extending cantilevered from one side of the fitting portion 5. In actual installation, the shape of the fitting portion 5 is designed to conform to the assembly groove (not shown) on the feeding disc; for example, the fitting portion 5 can be precisely inserted into the rectangular groove or T-groove of the feeding disc. The cantilevered fixing portion 2 rests on the surface of the feeding disc. This structure allows the mounting base 1 to achieve initial precise positioning and structural support through the fitting portion 5, and then final locking and fixing through the fixing portion 2, resulting in a very stable and precise installation.

[0021] Furthermore, to improve adjustability during installation, the fixing part 2 is preferably provided with a waist groove 21 that can cooperate with fasteners. Compared with traditional circular fixing holes, the waist groove 21 allows for small-range positional adjustments along the length of the sensing fiber seat before final locking. This design effectively compensates for tolerances accumulated during equipment manufacturing and installation, ensuring that the fiber hole 4 can be accurately aligned with the target position to be sensed, thus improving installation flexibility and alignment accuracy.

[0022] Furthermore, as a preferred embodiment, the mounting base 1 also integrates an active material attitude correction air path. Specifically, the mounting base 1 is provided with at least one blowing hole 6 and one air inlet 7. These two holes are connected inside the mounting base 1 through an integrally machined internal air path. The air inlet 7 is suitable for connecting to an external air source, such as a pneumatic quick-connect fitting for connecting to an air pipe, while the blowing hole 6 faces the material sensing area. This integrated design enables the sensing fiber optic mount to achieve a high degree of synergy between sensing and execution. In this embodiment, the sensing fiber optic cable within the fiber optic hole 4 is used to detect whether the LED material on the feeding disc is facing up. When facing up material is detected, the control system (not shown) immediately controls the air source, causing the blowing hole 6 to instantly eject airflow. The impact force of this airflow is used to flip the facing up material, making it face up, thereby effectively increasing the supply saturation of the facing material, significantly improving the automation level and yield of the spectrometer, and realizing the integration of sensing and correction functions.

[0023] Furthermore, as a preferred gas path layout, the location of the gas path port is carefully designed. For example... Figure 4 and Figure 5 As shown, the air blowing hole 6 is located on the same side adjacent to the fiber optic hole 4, and preferably above the fiber optic hole 4. This position allows the blown airflow to precisely cover the sensing area of ​​the fiber optic cable, achieving efficient cleaning. The air inlet 7 is preferably located on the top surface of the mounting base 1. This layout facilitates the connection of the air pipe from above the device without interfering with the installation space of the fixing part 2 or the interlocking part 5 of the mounting base.

[0024] Furthermore, to achieve the desired blowing effect, a specific dimensional relationship can be satisfied between the diameter D of the air inlet 7 and the diameter d of each of the blowing holes 6. In this embodiment, this relationship preferably satisfies: 2.9d ≤ D ≤ 3.2d. More preferably, D = 3d. For example, when the diameter d of the blowing hole 6 is 1 mm, the diameter D of the air inlet 7 can be set to 3 mm. This diameter configuration relationship, optimized by hydrodynamics, can ensure sufficient air intake while forming a high-speed focused airflow at the blowing hole 6, thereby achieving a highly efficient and powerful cleaning effect. Of course, those skilled in the art can appropriately adjust this proportional relationship according to the actual required air pressure and flow rate.

[0025] Additionally, as an optional optimization, one end of the fixing part 2 can be chamfered. This chamfering (e.g., C1 chamfer) not only removes any sharp edges that may be generated after processing, preventing installers from being scratched during installation and improving operational safety, but also facilitates the insertion and positioning of the mounting base 1 during installation.

[0026] In this embodiment, the mounting base 1 is preferably made of aluminum alloy through CNC precision machining. Aluminum alloy has advantages such as light weight, good rigidity, high dimensional stability, and ease of precision machining, making it very suitable for use in high-precision equipment such as LED spectrometers that require electrostatic protection. Of course, this embodiment is not limited to this; the mounting base 1 can also be made of other metal materials such as stainless steel or engineering plastics with sufficient rigidity and antistatic properties, depending on cost and performance requirements.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
