Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a testing device for rapidly inspecting the end face of a fiber optic array unit. Background Technology

[0002] FAU (Fiber Array Unit) is an indispensable core passive optical device in the field of optical communication. It acts as a precise optical signal "hub" by arranging and fixing multiple optical fibers with micron-level precision to achieve efficient coupling and stable transmission of multiple optical signals. It plays a key role, especially in high-density interconnection of optical modules and optical chip coupling.

[0003] With the maturing development of the optical communication market, the demand for fiber optic array units is increasing, market competition is fierce, and prices are highly sensitive. Therefore, a high degree of standardization and precision in product manufacturing is essential for the healthy development of enterprises. Currently, after polishing, fiber optic array units need to be individually clamped, wiped, and inspected, resulting in extremely low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rapid inspection device for the end face of a fiber optic array unit that can effectively improve inspection efficiency.

[0005] To achieve the above objectives, this utility model provides a rapid inspection device for the end face of a fiber optic array unit, comprising a rotating table, a mounting frame, a support assembly, and an inspection instrument. The mounting frame is mounted on the rotating table and can rotate with the rotating table. The mounting frame includes a base plate, a top plate, and a column. The two ends of the column are respectively connected to the base plate and the top plate. A receiving space is formed between the top plate and the base plate. The top plate is provided with a first through hole and a placement groove. The placement groove is recessed in the top wall of the top plate. The first through hole is located in the placement groove and penetrates downward through the top plate. The placement groove communicates with the receiving space through the first through hole. The support assembly includes a bracket and a polishing disc. The bracket is detachably mounted in the placement groove and the first through hole. The polishing disc is mounted on the bracket and is provided with multiple clamping components for clamping products. The inspection instrument is vertically movable and is located on one side of the mounting frame and directly above the placement groove.

[0006] As can be seen from the above solution, by setting up a rotary table, the mounting frame and the supporting components, as well as the products on them, can be driven to rotate synchronously. This facilitates the rotation to the next set of products after the detector has finished inspecting one set, which helps to improve inspection efficiency. Moreover, the rotary table can precisely control its rotation angle, ensuring that each rotation is performed at the preset angle, and ensuring that the product is rotated exactly under the detector. By setting up a mounting frame, it is convenient for staff to place the grinding disc and the bracket together on the mounting frame without having to remove the bracket, which helps to save time and improve work efficiency.

[0007] A further option is that the first perforation and the placement groove are respectively provided with a first opening and a second opening facing the same side, and the first opening and the second opening are connected.

[0008] A further option is to provide two protrusions between the center of the first perforation and the first opening, with the two protrusions positioned opposite each other and spaced apart by a preset distance, the preset distance being less than the width of the first opening.

[0009] A further option is to provide an arc-shaped groove wall in the placement slot, which matches the peripheral wall of the bracket.

[0010] As can be seen from the above scheme, the above settings are conducive to the positioning of the load-bearing components.

[0011] A further embodiment is that the bracket includes a support plate and a support column, one end of which is connected to the support plate, and the end of the support column protrudes from the top wall of the support plate to form an insertion part; the grinding disc has a mounting hole, which is connected to the insertion part.

[0012] As can be seen from the above scheme, the above settings ensure that the grinding disc can be placed stably and securely on the tray, preventing it from accidentally falling off the tray during movement.

[0013] A further solution is to have multiple clearance holes on the pallet, with each clearance hole corresponding to a clamping component.

[0014] A further embodiment is that the grinding disc is provided with multiple product fixing areas, which are evenly arranged at intervals along the circumference, and each product fixing area is provided with a corresponding clamping component; multiple mounting slots are arranged in the product fixing areas; the clamping component includes a first mounting block, a second mounting block, multiple pressure blocks, and multiple adjusting components. The first mounting block is disposed between the mounting slot and the second mounting block, the pressure block is slidably disposed in the first mounting block, and a clamping opening is formed between the pressure block and the mounting slot. The first end of the adjusting component is connected to the pressure block, and the second end of the adjusting component penetrates through the second mounting block. The depth to which the adjusting component is inserted into the second mounting block is adjustable. A further option is that the first mounting block has multiple second through holes, the shape of which matches the shape of the pressure block; the second mounting block has multiple screw holes, and the adjusting component is threadedly connected to the screw holes.

[0015] A further embodiment is that locking holes are provided on both sides of the product fixing area, first adjustment holes are provided at both ends of the first mounting block, and second adjustment holes are provided at both ends of the second mounting block; the clamping assembly also includes two locking fasteners, which pass through the second adjustment holes and the first adjustment holes and are connected to the corresponding locking holes, and the positions of the locking fasteners in the first adjustment holes and the second adjustment holes are adjustable. A further solution is to provide a pad at one end of the pressure block for direct contact with the product. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0022] See Figures 1 to 4 The rapid inspection device for the end face of fiber array units provided in this embodiment includes a rotating stage 1, a mounting frame 2, a support component 3, and an inspection instrument 4.

[0023] Mounting bracket 2 is mounted on rotating table 1 and can rotate synchronously with rotating table 1. Rotating table 1 can be manual or electric, and there is no restriction here. The setting of rotating table 1 can accurately control the angle of rotation of rotating table 1 each time, ensuring that the product on it is rotated exactly below the detector 4.

[0024] The mounting frame 2 includes a base plate 21, a top plate 22, and four uprights 23. The base plate 21 is fixedly connected to the rotating platform 1. The four uprights 23 are respectively located at the four corners of the base plate 21. The two ends of each upright 23 are connected to the base plate 21 and the top plate 22, respectively. An accommodating space is formed between the top plate 22 and the base plate 21. The top plate 22 is provided with a first through hole 221 and a placement groove 222. The placement groove 222 is recessed in the top wall of the top plate 22. The first through hole 221 is located in the placement groove 22 and extends downward through the top plate 22. The placement groove 222 communicates with the accommodating space through the first through hole 221.

[0025] The support component 3 includes a bracket 31 and a grinding disc 32. The bracket 31 is detachably disposed in the placement groove 222 and the first through hole 221. The support column 312 of the bracket 31 is disposed in the accommodating space. The grinding disc 32 is disposed on the bracket 31 and is provided with a plurality of clamping components 6 for clamping the product.

[0026] A mounting post 5 is provided on one side of the mounting bracket 2. A lifting adjustment seat 51 is mounted on the mounting post 5. The detector 4 is mounted on the mounting post 5 and positioned directly above the placement slot 222 via the lifting adjustment seat 51. The lifting adjustment seat 51 is equipped with a coarse adjustment knob and a fine adjustment knob. The coarse adjustment knob is used to quickly adjust the height of the detector 4, while the fine adjustment knob is used to finely adjust the height of the detector 4, thereby adjusting the focus and sharpness. The detector 4 can be a stereo microscope or a camera; there is no limitation here.

[0027] exist Figure 3 In the first perforation 221 and the placement groove 222, a first opening 2211 and a second opening are respectively provided on the same side, and the first opening 2211 and the second opening are vertically connected. Two protrusions 2212 are provided between the middle of the first perforation 221 and the first opening 2211. The two protrusions 2212 are arranged opposite each other and spaced apart by a preset distance, which is less than the width of the first opening 2211.

[0028] The placement groove 222 is designed as a "U" shaped groove. The end of the placement groove 222 away from the second opening is provided with an arc-shaped groove wall. The arc-shaped groove wall matches the peripheral wall of the bracket 31 and plays a positioning role.

[0029] exist Figure 4 In the bracket 31, there are a support plate 311 and a support column 312. The upper part of the support column 312 is fixedly connected to the center of the support plate 311, and the upper end of the support column 312 protrudes from the top wall of the support plate 311 to form an insertion part 3121. The support plate 311 has six clearance holes 3111, which penetrate through the thickness direction of the support plate 311. The six clearance holes 3111 are correspondingly arranged with six clamping components 6.

[0030] The grinding disc 32 has a mounting hole 321 at its center, which is connected to the insertion part 3121. The mounting hole 321 can penetrate through the thickness direction of the grinding disc 32, or it can be recessed into the bottom wall of the grinding disc 32. There is no limitation on this.

[0031] See Figure 4 and Figure 5 The grinding disc 32 has a hexagonal structure and six product fixing areas. Each product fixing area corresponds to one of the six sides of the grinding disc 32, and each product fixing area is equipped with a clamping component 6. Specifically: The product fixing area has four mounting slots 322 arranged in a row. Each mounting slot 322 can hold a product. In this embodiment, the product is a fiber optic array unit.

[0032] The clamping assembly 6 includes a first mounting block 61, a second mounting block 62, four pressure blocks 63, and four adjusting members 64. The first mounting block 61 is disposed between the mounting groove 322 and the second mounting block 62. The pressure blocks 63 are slidably disposed within the first mounting block 61, and a clamping opening for clamping and fixing the product is formed between the pressure blocks 63 and the mounting groove 322. The pressure blocks 63 are provided with T-slots, and the first end of the adjusting member 64 is engaged in the T-slot and can rotate relative to the pressure block 63. The second end of the adjusting member 64 passes through the second mounting block 62, and the depth of insertion of the adjusting member 64 into the second mounting block 62 is adjustable to drive the pressure block 63 to move linearly, thereby releasing or clamping the product. The first mounting block 61 has four second through holes 611, the shape of which matches the shape of the pressure block 63. The second through holes 611 are rectangular holes with four holes connected end to end. The four holes are respectively adjacent to the four side walls of the pressure block 63, serving to guide and restrict the pressure block 63 from tilting.

[0033] The second mounting block 62 has four screw holes 621. The adjusting member 64 is threadedly connected to the screw holes 621. By turning the adjusting member 64, the depth of its insertion into the screw holes 621 can be adjusted. Since the adjusting member 64 is circumferentially connected to the pressure block 63, the rotation of the adjusting member 64 will not cause the pressure block 63 to rotate. The pressure block 63 can only move linearly with the adjusting member 64.

[0034] Locking holes 323 are provided on both sides of the product fixing area, and four mounting slots 322 are arranged between two locking holes 323. First adjusting holes 612 are provided at both ends of the first mounting block 61, and second adjusting holes 622 are provided at both ends of the second mounting block 62. Both the first adjusting holes 612 and the second adjusting holes 622 are oblong holes. The locking holes 323, the first adjusting holes 612, and the second adjusting holes 622 are connected to each other.

[0035] The clamping assembly 6 also includes two locking fasteners (not shown in the figure), which pass through the second adjustment hole 622 and the first adjustment hole 612 and are connected to the locking hole 323. The locking fasteners are preferably screws, and their positions within the first adjustment hole 612 and the second adjustment hole 622 are adjustable, facilitating left and right adjustments to the positions of the first mounting block 61 and the second mounting block 62 to ensure that the pressure block 63 can accurately abut against the product in the corresponding mounting slot 322. One end of the pressure block 63 is provided with a pad 65 for direct contact with the product. The pad 65 can be made of rubber, silicone or plastic to avoid scratching the product surface.

[0036] In summary, this utility model, by setting a rotating stage 1, can drive the mounting frame 2 and the supporting component 3 and the products on them to rotate synchronously, which is convenient for rotating to the next set of products after the detector 4 has finished inspecting one set of products, thus improving inspection efficiency. Moreover, the rotating stage 1 can precisely control its rotation angle, ensuring that each rotation is performed at the preset angle, and ensuring that the product is rotated exactly below the detector 4. By setting the mounting frame 2, it is convenient for the staff to place the grinding disc 32 together with the bracket 31 on the mounting frame 2, without having to remove the bracket 31 during the process, which saves time and improves work efficiency.

[0037] Finally, it should be emphasized that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. 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.
