[0034] For details, please refer to Figures 1 to 4 , the embodiment of the present application provides an optical fiber automatic centering tray 1, the tray 1, the upper surface of the tray 1 is provided with a clamping mechanism 2, the clamping mechanism 2 includes at least one set of clamping components 3, the clamping component 3 includes a first fixing clamp 31 and a second fixing clamp 32, the positions of the first fixing clamp 31 and the second fixing clamp 32 correspond to each other;
[0035] The first fixing clamp 31 and the second fixing clamp 32 are both provided with a fixing groove 30 for the optical fiber end to be inserted into. The first fixing clamp 31 and the second fixing clamp 32 are both formed with two supporting surfaces 301 through the fixing grooves 30 provided therein. The two supporting surfaces 301 are arranged at an angle to receive the optical fiber and support the outer periphery of the optical fiber.
[0036] The height from the supporting surface 301 of the first fixing clamp 31 to the upper surface of the material tray 1 is equal to the height from the second fixing clamp 32 to the upper surface of the material tray 1 .
[0037] Through the above-mentioned arrangement, the first fixing clamp 31 and the second fixing clamp 32 can clamp the two ends of the optical fiber during packaging. Since the first fixing clamp 31 and the second fixing clamp 32 form two supporting surfaces 301 through the fixing groove 30 opened by themselves, and the two supporting surfaces 301 are arranged at an angle, when the optical fiber end is placed in the fixing groove 30 and the two supporting surfaces 301 are in contact, the two supporting surfaces 301 provide support for the optical fiber end. Therefore, for optical fibers with different outer diameters, the two supporting surfaces 301 can provide support points adapted to the optical fiber diameter for optical fibers with different diameters, so that optical fibers of different sizes are fixed at different heights of the first fixing clamp 31 or the second fixing clamp 32 through the inner wall of the fixing groove 30. Since the height from the supporting surface 301 of the first fixing clamp 31 to the upper surface of the material tray 1 is equal to the height from the second fixing clamp 32 to the upper surface of the material tray 1, the heights of the two ends of the optical fiber can always be kept at the same height, thereby achieving the effect of centering the optical fiber axis.
[0038] Reference Figure 1 and Figure 2In some embodiments of the present application, the material tray 1 is in the shape of a rectangular plate, and the upper surface of the material tray 1 is divided into a placement area 11 corresponding to the clamping mechanism 2. The upper surface of the material tray 1 is also divided into two product areas 12 for placing products. Along the length direction of the material tray 1, the two product areas 12 are correspondingly arranged on both sides of the placement area 11; the product area 12 is fixedly connected with a plurality of second positioning pins 5. Among them, the highest height of the second positioning pins 5 is greater than the highest height when the optical fiber is clamped and fixed to the first fixing clamp 31 and the second fixing clamp 32.
[0039] Thus, when clamping and fixing the optical fiber, after the lower layer of tray 1 has fixed the product, the second layer of tray 1 can be stacked and fixed and the fixing process of the second layer of product can be continued, so that the products (including optical fiber, base, positioning seat, etc.) on the multiple layers of trays 1 can be fixed in one spatial position, reducing the space occupied by the tray 1 when fixing the product.
[0040] Reference Figure 2 and Figure 3 In some embodiments of the present application, the angle α between the two supporting surfaces 301 corresponding to each fixing groove 30 is in the range of 50-90°, the vertical section of the fixing groove 30 is V-shaped, and the supporting surface 301 is tangent to the outer surface of the optical fiber. At the same time, the two supporting surfaces 301 are mirror-symmetrical along the vertical section passing through the intersection of the two supporting surfaces 301. Therefore, one of the supporting surfaces 301 deviates to one side by 1 / 2 of the angle α relative to the vertical section, and the other supporting surface 301 also deviates in the opposite direction by the same angle.
[0041] Therefore, when the optical fiber is fixed to two supporting surfaces 301, the outer peripheral wall of the optical fiber is tangent to the two supporting surfaces 301. In the horizontal direction, the first horizontal distance from the contact point of the outer peripheral wall of the optical fiber with one supporting surface 301 to the vertical section is equal to the second distance from the contact point of the outer peripheral wall of the optical fiber with the other supporting surface 301 to the vertical section. Therefore, when the two supporting surfaces 301 of the fixing groove 30 are smooth, the center axis of the optical fiber will not be laterally offset in the horizontal direction; similarly, at different positions along the length of the optical fiber, the vertical distance from the center axis of the optical fiber to the intersection of the two supporting surfaces 301 is also equal, so that the optical fiber can have an equal height effect in the length direction.
[0042] For example, when one end of the optical fiber is clamped in the first fixing clamp 31 with the angle α between the two supporting surfaces 301 being 60°, the optical fiber has a centering effect along the length direction.
[0043] like Figure 4As shown, the angle α between the two support surfaces 301 is in the range of 60°. At the same time, the two support surfaces 301 are mirror-symmetrical along the vertical section passing through the intersection line of the two support surfaces 301. Therefore, one of the support surfaces 301 deviates by 30° relative to the vertical section, and the other support surface 301 deviates by -30° relative to the vertical section. Since both support surfaces 301 deviate from the vertical section by an angle α of 1 / 2 to both sides, when the optical fiber is fixed to the two support surfaces 301, the shortest distance from the optical fiber center axis to the contact point between the optical fiber outer wall and one support surface 301 is the first distance, and the shortest distance from the optical fiber center axis to the contact point between the optical fiber outer wall and the other support surface 301 is the second distance. The above contact points are all points where the optical fiber periphery is tangent to the support surface 301. Therefore, the first distance and the second distance are both equal to the radius of the optical fiber, and the angles corresponding to the first distance and the second distance are both 30°. Therefore, at different positions along the length of the optical fiber, the vertical distance from the optical fiber center axis to the intersection of the two support surfaces 301 is also equal, so that the optical fiber can have an equal height effect in the length direction, and the optical fiber is centered at this time.
[0044] Therefore, it is only necessary that the corresponding second fixing clamp 32 and the supporting surface 301 of the first fixing clamp 31 are at the same height and the positions fixed on the material tray 1 are collinear, so that automatic centering can be achieved when the two ends of the optical fiber are clamped.
[0045] In some embodiments of the present application, a plurality of clamping assemblies 3 are provided, and the plurality of clamping assemblies 3 are arranged at intervals in the placement area 11 to form a clamping mechanism 2. Through the plurality of clamping assemblies 3, a plurality of arranged optical fibers can be clamped simultaneously on a tray 1.
[0046] Correspondingly, in some embodiments of the present application, the material tray 1 is also fixedly provided with a plurality of first positioning pins 4, and the first positioning pins 4 are correspondingly arranged between the first fixing clamp 31 and the second fixing clamp 32. The first positioning pins 4 are used to fix the corresponding packaging product, such as a base, to package the optical fiber into the base. The maximum height of the first positioning pins 4 is also greater than the maximum height when the optical fiber is clamped and fixed to the first fixing clamp 31 and the second fixing clamp 32. At the same time, the maximum height of the first positioning pins 4 also needs to be greater than the maximum height when the product is fixed to the upper part of the material tray 1.
[0047] The first positioning pin 4 can fix the base of the corresponding housing product or the positioning seat of the glass tube product during packaging, and a corresponding pin hole is opened on the base or the positioning seat, and the first positioning pin 4 passes through the pin hole to fix the corresponding positioning seat, thereby correspondingly packaging the optical fiber into the corresponding base or the positioning seat.
[0048] In some embodiments of the present application, the first fixing clamp 31 and the second fixing clamp 32 both include a clamp bottom 311 and a clamp cover 312; the clamp bottom 311 is fixedly mounted on the upper surface of the material tray 1, and the clamp cover 312 is rotatably mounted on the clamp bottom 311; the fixing groove 30 is opened on the top surface of the clamp bottom 311, and the clamp cover 312 can be rotated to cover the upper part of the fixing groove 30, and the clamp cover 312 can be rotated to abut against the top of the outer wall of the optical fiber.
[0049] A countersunk groove 3111 can be opened on the clamp bottom 311, and a countersunk bolt is used to pass through the countersunk groove 3111 and threadedly connected to the material tray 1, so as to fix the clamp bottom 311 to the upper surface of the material tray 1 to complete the fixation of the first fixing clamp 31 or the second fixing clamp 32.
[0050] In some embodiments of the present application, the opening direction of the fixing groove 30 is the same as the axial direction of the optical fiber when it is clamped and fixed; the clamping cover 312 is rotatably mounted on the clamping bottom 311 through the pin shaft 3112, and along the length direction of the fixing groove 30, the axis of the rotating shaft of the clamping cover 312 is arranged in the same direction as the opening direction of the fixing groove 30; along the axial direction of the rotating shaft of the clamping cover 312, the length of the fixing groove 30 is greater than the length of the clamping cover 312;
[0051] Therefore, when the optical fiber is fixed by the clamping cover 312 , the sight line will not be completely blocked by the clamping cover 312 , which is convenient for the operator to observe and adjust the clamping effect in time.
[0052] In addition, a surface of the clamping cover 312 that can rotate to abut against the top of the outer wall of the optical fiber is provided with an escape groove 3121 , and the length direction of the escape groove 3121 is in the same direction as the length direction of the fixing groove 30 .
[0053] The avoidance groove 3121 enables the clamp cover 312 to abut against the top of the outer wall of the optical fiber after rotation, while avoiding or limiting the phenomenon that the clamp cover 312 interferes with the outer wall of the optical fiber during rotation due to the protrusion of the optical fiber from the upper surface of the clamp bottom 311 due to its large diameter.
[0054] In some embodiments of the present application, an elastic layer is provided on the wall surface corresponding to the avoidance groove 3121, and the clamping cover 312 is movably attached to the top of the outer wall of the optical fiber through the elastic layer. In addition, a connecting piece 313 is provided on the clamping cover 312, and when the clamping cover 312 rotates to cover the upper part of the fixing groove 30, the connecting piece 313 restricts the clamping cover 312 from being separated from the clamping bottom 311.
[0055] For example, the elastic layer is selected to be a silicone layer, and the silicone layer is fixed by gluing or embedding. The thickness of the silicone layer protrudes 0-0.2mm from the surface of the clamp cover 312. The specific thickness can be adaptively adjusted according to the connection strength of the connector 313. Any method that can clamp and fix the optical fiber and ensure that there is no obvious gap between the clamp cover 312 and the clamp bottom 311 and the optical fiber is not loose after the clamp cover 312 is rotated and closed is acceptable.
[0056] The thickness of the silicone layer protrudes from the surface of the clamp cover 312 by 0-0.2mm, so that after the connector 313 fixes the clamp cover 312, the silicone layer can provide a certain buffer for the outer wall of the optical fiber to avoid or reduce pressure, and at the same time will not affect the fixing effect of the clamp cover 312 on the top of the optical fiber.
[0057] In some embodiments of the present application, the connector 313 includes a magnet 1 and a magnet 2 (not shown), the magnet 1 and the magnet 2 are connected by magnetic attraction, the magnet 1 is fixedly connected to the clamp cover 312, and the magnet 2 is fixedly connected to the clamp bottom 311. The magnet 1 and the magnet 2 can be fixed by opening corresponding grooves, bonding and embedding them in the grooves through colloid.
[0058] Of course, the connecting piece 313 can also be replaced. For example, the clamp cover 312 can be a clamp cover 312 made of magnetic material. After the clamp cover 312 is flipped over and closed, the contact part corresponding to the clamp bottom 311 is made of a material with opposite magnetism, thereby achieving automatic suction when closed.
[0059] In order to facilitate the opening of the boundary after the clamp cover 312 is closed, the clamp cover 312 can be provided with a first protrusion. When the clamp cover 312 is covered to the clamp bottom 311, the protrusion protrudes horizontally from the side of the clamp bottom 311, thereby facilitating the operator to pull the clamp cover 312 to close or open.
[0060] Of course, in order to improve the clamping stability of the optical fiber, in some embodiments, a threaded hole is opened on the upper surface of the clamp bottom, and a through hole is opened on the clamp cover 312. After the clamp cover 312 is covered to the upper part of the clamp bottom 311, the through hole corresponds coaxially with the threaded hole. A bolt is used to pass through the through hole on the upper part of the clamp cover 312 and threadedly connected to the threaded hole, which can further prevent the clamp cover from detaching from the clamp bottom.
[0061] As an example, the clamp bottom 311 is fixedly connected to a second protrusion. When the clamp cover 312 is flush with the upper surface of the clamp bottom, the first protrusion and the second protrusion are overlapped in the height direction, and a threaded hole is opened in the second protrusion, thereby achieving the effect of improving the clamp cover 312 on clamping the optical fiber while facilitating the operator to pull the clamp cover 312 to close or open.
[0062] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
