Description

Technical Field

[0001] This utility model relates to the field of microscopic imaging module observation technology, and in particular to a fiber optic ceramic end face testing instrument. Background Technology

[0002] In the optical fiber manufacturing process, microscopic video inspection of the fiber end face is required to ensure processing quality and end face cleanliness. During inspection, the optical fiber is usually inserted into the fiber optic connector first, and then the fiber optic connector is inserted into the fiber end face inspection device for inspection. However, the difficulty in the inspection process lies in finding the initial position of the fiber end face. Existing inspection methods rely solely on manually adjusting the position of the fiber optic connector to find the initial position of the fiber end face, which results in low accuracy and low inspection efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an optical fiber ceramic end-face testing instrument that can quickly adjust and locate the position of the optical fiber end-face for observation.

[0006] The mounting base is disposed on the upper end face of the dual-axis displacement stage, and the mounting base is provided with a product mounting position. The dual-axis displacement stage is adapted to adjust the position of the mounting base in the front-back direction and the left-right direction.

[0007] A microscopic imaging module is provided, which is spaced apart from the mounting base. The microscopic imaging module includes a magnifying eyepiece group and a light source. The magnifying eyepiece group includes lenses with multiple magnifications. The observation direction of the magnifying eyepiece group is opposite to the product mounting position. The light beam of the light source passes horizontally through the magnifying eyepiece group to reach the product mounting position.

[0008] The display module is electrically connected to the microscopic imaging module.

[0009] According to some embodiments of the present invention, the dual-axis displacement stage includes a Y-axis moving component and an X-axis moving component connected sequentially from bottom to top. The mounting base is disposed on the upper end surface of the X-axis moving component. The Y-axis moving component is adapted to drive the X-axis moving component and the mounting base to move in the front-back direction, and the X-axis moving component is adapted to drive the mounting base to move in the left-right direction.

[0010] According to some embodiments of the present invention, the Y-axis moving component includes a first fixed member, a first adjusting bolt passing through the first fixed member, a first movable member passing through the first adjusting bolt, the first movable member being able to move relative to the first fixed member in the front-back direction via the first adjusting bolt, and the X-axis moving component being mounted on the first movable member.

[0011] According to some embodiments of the present invention, the first movable component is located at the front end of the first fixed component, and the microscopic imaging module is installed on the rear side of the upper end face of the first fixed component.

[0012] According to some embodiments of the present invention, the X-axis moving assembly includes a second fixed member, a second adjusting bolt passing through the second fixed member, a second movable member passing through the second adjusting bolt, the second movable member being able to move in the left and right directions relative to the second fixed member through the second adjusting bolt, the mounting base being mounted on the second movable member, and a limiting member passing vertically through the second movable member, the limiting member being able to contact the second fixed member.

[0013] According to some embodiments of the present invention, the mounting base includes a base and a third connecting member installed at the center of the base. The base is disposed on the second movable member, and the third connecting member has a product mounting position at its center.

[0014] According to some embodiments of this utility model, the base is provided with several through slots and positioning bolts. The positioning bolts are vertically installed on the upper surface of the dual-axis displacement platform, and the base can be horizontally engaged with the positioning bolts through the several through slots.

[0015] According to some embodiments of the present invention, the upper surface of the dual-axis displacement stage is adapted to have multiple mounting seats arranged side by side from left to right.

[0016] According to some embodiments of the present invention, the magnifying eyepiece group includes a rotary dial and a first eyepiece, a second eyepiece, and a third eyepiece mounted on the rotary dial. The magnification coefficients of the first eyepiece, the second eyepiece, and the third eyepiece are different, and the first eyepiece, the second eyepiece, and the third eyepiece can be sequentially aligned with the product mounting position via the rotary dial.

[0019] By using a mounting base on a dual-axis displacement stage in conjunction with a magnifying eyepiece assembly with multiple magnification lenses and a light source, the problem of finding the initial position of the fiber optic end face and the need for repeated manual adjustments is significantly solved. The dual-axis displacement stage enables precise positioning of the fiber optic connector in the left-right direction and positioning and focusing in the front-back direction. The magnifying eyepiece assembly with multiple magnification lenses quickly locates the inspection end face through the low-magnification lens and, in conjunction with the dual-axis displacement stage, moves left-right to the relative center position of the microscopic imaging module. Then, it switches to high magnification to move one step further to the relative center position until the end face of the inspected product can be clearly observed in the image. It can continuously position and magnify until the end face of the product under test is clearly detected, improving inspection efficiency. The design of the light source facilitates clear imaging, and the integrated display module ensures real-time image presentation.

Furthermore, features defined as "first," "second," and "third" may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "several" means two or more.

[0033] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0034] The following is for reference. Figures 1 to 3 This invention describes a fiber optic ceramic end face testing instrument according to an embodiment of the present invention.

[0035] Combination Figures 1 to 3 As shown, the fiber optic ceramic end face testing instrument according to an embodiment of the present invention includes: a dual-axis displacement stage 100, a mounting base 200, a microscopic imaging module 300, and a display module 400.

[0036] Mounting base 200 is disposed on the upper surface of dual-axis displacement stage 100. Mounting base 200 is provided with product mounting position 210. Dual-axis displacement stage 100 is adapted to adjust the position of mounting base 200 in the front-back direction and the left-right direction. Microscopic imaging module 300 is disposed at an interval from mounting base 200. Microscopic imaging module 300 includes magnifying eyepiece group 310 and light source 320. Magnifying eyepiece group 310 includes lenses with multiple magnifications. The observation direction of magnifying eyepiece group 310 is opposite to product mounting position 210. The beam of light from light source 320 passes horizontally through magnifying eyepiece group 310 to reach product mounting position 210. Display module 400 is electrically connected to microscopic imaging module 300.

[0037] When using the instrument, the product mounting position 210 of the mounting base 200 is suitable for connecting with the product under test. After inserting the product under test into the mounting base 200 facing the microscope imaging module 300, first use the eyepiece with a smaller magnification in the magnifying eyepiece group 310 to find the end face of the product under test. Then use the dual-axis displacement stage 100 to adjust the position of the product under test so that the end face of the product under test moves to the center position of the microscope imaging module 300. Then replace the eyepiece with a larger magnification in the magnifying eyepiece group 310, and further adjust the position of the product under test by using the dual-axis displacement stage 100 so that the product under test moves to the center position of the microscope imaging module 300 with each magnification until the end face of the product under test can be completely observed.

[0038] It is understandable that the setting of the light source 320 can illuminate the product mounting position 210, so that the imaging image of the microscopic imaging module 300 is clear. When the light source in the light source 320 is not set parallel to the product mounting position 210, a lens can be set inside to refract the light so that the beam of the light source 320 passes horizontally through the magnifying eyepiece group 310 to reach the product mounting position 210.

[0039] It is understandable that the center position of the microscopic imaging module 300 and the center position of the product mounting position 210 are at the same height on the horizontal plane. Therefore, during the test, only the position adjustment in the left and right direction is needed to make the center position of the product under test reach the center position of the microscopic imaging module 300. Then, the front and back distance can be adjusted appropriately so that the magnifying eyepiece group 310 can better focus on the product under test, thereby presenting a complete and clear end face.

[0040] Understandably, the display module 400 can receive the end face conditions observed by the magnified microscopic imaging module 300, making it convenient for inspection personnel to observe. The display module 400 can also provide power to the microscopic imaging module 300 and the light source 320 through electrical connection, and control the switching of the entire instrument.

[0041] In some specific embodiments of this utility model, the dual-axis displacement stage 100 includes a Y-axis moving component 110 and an X-axis moving component 120 connected sequentially from bottom to top. The mounting base 200 is disposed on the upper end face of the X-axis moving component 120. The Y-axis moving component 110 is adapted to drive the X-axis moving component 120 and the mounting base 200 to move in the front-back direction, and the X-axis moving component 120 is adapted to drive the mounting base 200 to move in the left-right direction.

[0042] Combination Figure 1 and Figure 2 As shown, in this embodiment, the superposition design of the X-axis moving component 120 and the Y-axis moving component 110 can simplify the size of the instrument to the greatest extent. Furthermore, the design of the X-axis moving component 120 being positioned above the Y-axis moving component 110 makes it easier to switch between different mounting bases 200 and achieve rapid testing of the next product.

[0043] In some specific embodiments of this utility model, the Y-axis moving component 110 includes a first fixing member 111, a first adjusting bolt 112 passing through the first fixing member 111, a first movable member 113 passing through the first adjusting bolt 112, and the first movable member 113 being able to move relative to the first fixing member 111 in the front-back direction through the first adjusting bolt 112. The X-axis moving component 120 is mounted on the first movable member 113.

[0044] Combination Figure 1 and Figure 2 As shown, in this embodiment, the first fixed member 111, the first adjusting bolt 112 and the first movable member 113 are connected in sequence. The first adjusting bolt 112 is fixed relative to the first fixed member 111 and can rotate. The first movable member 113 moves relative to the first fixed member 111 in the front-back direction by rotating.

[0045] It is understandable that a scale can be provided on the first adjusting bolt 112 for easy adjustment. It is also understandable that a sliding guide rail (not shown in the figure) that moves in the front-to-back direction can be provided between the first movable part 113 and the first fixed part 111 for auxiliary connection, serving a supporting function. It is also understandable that the design of the first fixed part 111, the first adjusting bolt 112, and the first movable part 113 is similar to a lead screw and slider structure, possessing high precision standards and facilitating fine-tuning.

[0046] In some specific embodiments of this utility model, the first movable member 113 is located at the front end of the first fixed member 111, and the microscopic imaging module 300 is installed on the rear side of the upper surface of the first fixed member 111.

[0047] Combination Figure 1 and Figure 3As shown, in this embodiment, the first movable component 113 and the microscopic imaging module 300 are located on the front and rear sides of the upper surface of the first fixed component 111, so that the instrument forms an integrated design, which is convenient for transportation and transfer.

[0048] Understandably, in order to make the instrument more compact and to ensure that the horizontal height of the center of the product mounting position 210 is consistent with the horizontal height of the center of the microscopic imaging module 300, the first fixing member 111 may also be provided with a groove to place the first adjusting bolt 112 and the first movable member 113, and the upper end surface of the first movable member 113 is higher than the upper end surface of the first fixing member 111 to prevent the lower end surface of the X-axis moving assembly 120 from rubbing against the upper end surface of the first fixing member 111 when moving back and forth.

[0049] In some specific embodiments of this utility model, the X-axis moving assembly 120 includes a second fixing member 121, a second adjusting bolt 122 passing through the second fixing member 121, a second movable member 123 passing through the second adjusting bolt 122, the second movable member 123 being able to move in the left and right directions relative to the second fixing member 121 via the second adjusting bolt 122, a mounting base 200 being mounted on the second movable member 123, a limiting member 124 being vertically passing through the second movable member 123, the limiting member 124 being able to contact the second fixing member 121.

[0050] Combination Figure 1 and Figure 2 As shown, in this embodiment, the second fixing member 121, the second adjusting bolt 122 and the second movable member 123 are connected in sequence. The second adjusting bolt 122 passes horizontally through the second fixing member 121 and can rotate. The second movable member 123 moves in the left and right directions relative to the second fixing member 121 by rotation.

[0051] It is understandable that a scale can be provided on the second adjusting bolt 122 for easy adjustment. It is also understandable that a sliding guide rail (not shown in the figure) that moves in the left-right direction can be provided between the second movable part 123 and the second fixed part 121 for auxiliary connection, serving a supporting function. It is also understandable that the design of the second fixed part 121, the second adjusting bolt 122, and the second movable part 123 is similar to a lead screw and slider structure, possessing high precision standards and facilitating fine-tuning.

[0052] In some specific embodiments of this utility model, the mounting base 200 includes a base 220 and a third connector 230 installed at the center of the base 220. The base 220 is disposed on the second movable member 123, and the third connector 230 has a product mounting position 210 at its center.

[0053] Combination Figure 2 and Figure 3As shown in this embodiment, the base 220 is designed for easy connection, and the third connector 230 is designed to make the mounting base 200 more adaptable. Different products to be tested can be tested by replacing different types of third connectors 230.

[0054] In some specific embodiments of this utility model, the base 220 is provided with several through slots 221 and positioning bolts 222. The positioning bolts 222 are vertically installed on the upper surface of the dual-axis displacement stage 100, and the base 220 can be horizontally engaged with the positioning bolts 222 through several through slots 221.

[0055] Combination Figure 2 As shown, in this embodiment, the base 220 has two through slots 221 that can be adapted to two positioning bolts 222. When installing the mounting base 200, the positioning bolts 222 can be initially installed on the upper surface of the dual-axis displacement stage 100, so that the upper surface of the positioning bolts 222 and the upper surface of the dual-axis displacement stage 100 are kept at a certain distance, allowing the base 220 to be inserted horizontally. Then, the positioning bolts 222 are tightened downwards, so that the base 220 can be stably fixedly connected to the dual-axis displacement stage 100. This design does not require completely loosening the connection between the positioning bolts 222 and the dual-axis displacement stage 100, and the mounting base 200 can be quickly removed and replaced, improving the efficiency of installation and removal.

[0056] In some specific embodiments of this utility model, the upper end face of the biaxial displacement stage 100 is adapted to have multiple mounting seats 200 arranged side by side from left to right. Figure 1 As shown, in this embodiment, there are three mounting bases 200. Three products under test can be installed at once using these three mounting bases 200, eliminating the need for frequent replacement and removal of the products during testing. This allows for simultaneous installation and removal, improving testing efficiency. It is understood that the number of mounting bases 200 should be determined based on the length of the upper surface of the dual-axis displacement stage 100 in the left-right direction.

[0057] In some specific embodiments of this utility model, the magnifying eyepiece group 310 includes a dial 311 and a first eyepiece 312, a second eyepiece 313 and a third eyepiece 314 mounted on the dial 311. The magnification coefficients of the first eyepiece 312, the second eyepiece 313 and the third eyepiece 314 are different. The first eyepiece 312, the second eyepiece 313 and the third eyepiece 314 can be sequentially aligned with the product mounting position 210 via the dial 311.

[0058] Combination Figure 3As shown, in this embodiment, a first eyepiece 312, a second eyepiece 313, and a third eyepiece 314 are mounted on the dial 311, with magnification increasing sequentially. When using the instrument, firstly, the first eyepiece 312 is aligned with the product mounting position 210 to locate the end face of the product to be tested. The end face is then moved to the center of the image observed by the first eyepiece 312 using the dual-axis displacement stage 100, and focused until clearly displayed on the display module 400. Next, the second eyepiece 313 is rotated to align with the product mounting position 210, locate the end face of the product to be tested, and then the end face is moved to the center of the image observed by the first eyepiece 312 using the dual-axis displacement stage 100. The stage 100 moves the end face to the center of the image observed by the second eyepiece 313 and focuses it to be clearly displayed on the display module 400. If the end face of the product under test can be clearly observed at this time, there is no need to use the third eyepiece 314. Otherwise, rotate the third eyepiece 314 to align with the product mounting position 210, find the end face of the product under test, and move the end face to the center of the image observed by the third eyepiece 314 through the dual-axis stage 100 and focus it to be clearly displayed on the display module 400 to complete the observation of the end face of the product under test.

[0059] Understandably, the dial 311 can be set with multiple eyepiece placement positions to accommodate eyepieces of different magnifications. Understandably, if the end face of the product under test cannot be clearly seen even when using the maximum magnification eyepiece, and it is not a focusing issue, a higher magnification eyepiece can be used instead.

[0060] In some specific embodiments of this utility model, it further includes a base 500, a dual-axis displacement stage 100, and a microscopic imaging module 300 mounted on the base 500, with a display module 400 located on one side of the base 500. Combined with... Figure 1 As shown, in this embodiment, the base 500 makes the overall transport of the instrument more convenient and improves the degree of instrument integration.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
