Description

Technical Field

[0001] The present application relates to the technical field of optical fiber array processing equipment, and in particular to a clamping fixture and a dispensing device. Background Art

[0002] A fiber array consists of a base plate, a pressure plate, and multiple fiber cores. The pressure plate fits over the base plate, and the connecting segments of the fiber cores are inserted between the base plate and the pressure plate. During the fiber production process, multi-channel fiber arrays often require glue application. Specifically, operators need to apply glue to the connecting segments of the fiber cores.

[0003] Currently, the commonly used glue dispensing method first fixes the fiber core, leaving the substrate, pressure plate, and the core's connecting section suspended in the air. Glue is then applied to the substrate, gradually covering it with glue, essentially enveloping the core's connecting section. However, this method presents numerous challenges, such as difficulty controlling the length and height of the glue dispensed. Utility Model Content

[0004] In view of this, the present application provides a clamping fixture and a dispensing device to improve the technical problem of poor dispensing effect of existing optical fiber arrays.

[0005] One embodiment of the present application provides a clamping fixture configured to secure an optical fiber array, wherein the substrate of the optical fiber array and the pressure plate of the optical fiber array jointly clamp a portion of the optical fiber array's core. The clamping fixture includes a carrier and a clamping assembly. The carrier has a carrier portion and a restraining portion connected to each other. The carrier portion is configured to support the pressure plate, and the restraining portion is configured to be spaced apart from the substrate to accommodate an adhesive for bonding the optical fiber array and a portion of the optical fiber core. The clamping assembly is configured to press the substrate toward the carrier portion when the carrier portion supports the optical fiber array.

[0006] In the aforementioned clamping jig, the user drips adhesive onto the jig, where it flows and settles between the substrate and the restraining portion, enveloping the fiber core held by the substrate and the pressure plate. Compared to applying glue directly to the substrate, gradually coating it, the jig uses the restraining portion and the substrate within the fiber array to control the shape, length, and height of the cured adhesive. By adjusting the spacing between the substrate and the restraining portion, as well as the length between the substrate and the restraining portion, the shape, length, and height of the glue can be controlled, improving the dispensing effect on the fiber array.

[0007] In some embodiments of the present application, the supporting portion includes a supporting surface, and the restraining portion includes a restraining surface. The supporting surface is configured to support a pressure plate. The restraining surface is configured to be spaced apart from the substrate and to restrain the flow of the adhesive. In a direction perpendicular to the supporting surface, the restraining surface is closer to the substrate than the supporting surface.

[0008] In the above embodiment, due to the surface tension characteristics and capillary action of the adhesive, by setting the constraint surface closer to the substrate than the supporting surface, the distance between the constraint surface and the substrate can be reduced, making it easier for the adhesive to be absorbed between the constraint surface and the substrate, thereby facilitating more sufficient filling of the adhesive between the constraint portion and the substrate, further improving the dispensing effect.

[0009] In some embodiments of the present application, the constraint portion is also provided with a stop surface, which connects the bearing surface and the constraint surface. The stop surface is configured to abut against the pressure plate when the bearing surface bears the pressure plate, so as to stop the pressure plate from moving along a first direction toward the direction close to the constraint portion, and the first direction is parallel to the bearing surface.

[0010] In the above embodiment, the clamping fixture can stop the pressure plate from moving along the first direction toward the constraint portion through the setting of the stop surface, so as to reduce the risk of shaking or deviation of the optical fiber array during the dispensing process, thereby ensuring that the optical fiber array is stably supported on the carrier and further improving the dispensing effect of the optical fiber array.

[0011] In some embodiments of the present application, the constraint portion is further provided with a guide surface, which is located on a side of the constraint surface away from the bearing surface, and the guide surface is configured to guide the adhesive to flow toward the constraint surface.

[0012] In the above embodiment, when adhesive drips onto the fixture, it flows along the guide surface to the constraining surface, that is, between the substrate and the constraining surface. The provision of the guide surface facilitates the flow of the adhesive toward the constraining surface and allows for more precise control of the adhesive's flow path. This not only ensures that the adhesive only covers the areas requiring bonding, but also reduces the risk of excessive or uneven adhesive application, thereby helping to better control the shape, height, and length of the cured adhesive.

[0013] In some embodiments of the present application, a clamping assembly includes a bracket, a rotating member, and a clamping member. The rotating member is mounted on the bracket and is configured to rotate relative to the bracket about a first axis, wherein the first axis is parallel to the support surface. The rotating member includes an operating portion and an action portion, wherein the operating portion and the action portion are located on either side of the first axis in a direction perpendicular to the support surface. The clamping member is connected to the action portion, and the operating portion is configured to drive the action portion to reciprocate in a direction perpendicular to the support surface, thereby causing the clamping member to press or release the substrate.

[0014] In the above-described embodiment, the cooperation between the rotating member and the pressing member enables the substrate in the optical fiber array to be pressed or released, that is, the optical fiber array can be pressed or released. When the optical fiber array needs to be fixed, the operating portion drives the rotating member to rotate about the first axis relative to the bracket, so that the action portion moves in a direction perpendicular to the bearing surface, thereby driving the pressing member to press the substrate. When the optical fiber array needs to be released, the operating portion drives the rotating member to rotate in the opposite direction about the first axis relative to the bracket, so that the action portion moves in the opposite direction, thereby driving the pressing member to release the substrate.

[0015] In addition, by arranging the action part and the operating part on both sides of the first axis, the clamping component can be prevented from obstructing or interfering with the user's glue dripping operation, making it easier for the user to drip the adhesive onto the loading jig, thereby improving the glue dispensing efficiency of the optical fiber array.

[0016] In some embodiments of the present application, the clamping assembly further includes a pushing member and an elastic member, the pushing member being mounted on the bracket, and the pushing member being configured to drive the operating part to move in a direction away from the substrate so that the clamping member releases the substrate; one end of the elastic member is connected to the operating part, and the other end is connected to the bracket, and the elastic member is configured to provide an elastic force to the operating part in a direction away from the substrate so that the clamping member presses the substrate.

[0017] In the above embodiment, the elastic member enables the clamping assembly to automatically maintain its grip on the substrate in the absence of external force. The pusher can, when necessary, apply force to the operating portion to release the clamping assembly from the substrate. The provision of the elastic member and pusher allows the clamping assembly to more precisely control the grip and release of the clamping assembly from the substrate, ensuring the stability of the optical fiber array during the dispensing process, thereby improving the efficiency and convenience of dispensing the optical fiber array.

[0018] In some embodiments of the present application, the pressing member is rotatably connected to the rotating member so that the pressing member can rotate relative to the rotating member around a second axis, and the second axis is parallel to the first axis.

[0019] In the above-described embodiment, the pressing member, driven by the rotating member, not only reciprocates perpendicularly to the bearing surface to compress or release the substrate, but also rotates relative to the rotating member about a second axis to accommodate optical fiber arrays of varying shapes and sizes, thereby enhancing the adaptability and flexibility of the fixture. Furthermore, the rotational connection between the pressing member and the rotating member reduces the risk of the pressing member and the substrate in the optical fiber array becoming stuck or stuck, facilitating smooth operation of the fixture and improving the efficiency of dispensing glue to the optical fiber array.

[0020] In some embodiments of the present application, the clamping fixture also includes a limit member, which is installed on the bearing surface and is configured to abut against the side walls of the pressure plate and the side walls of the substrate when the bearing portion bears the pressure plate to constrain the position of the optical fiber array.

[0021] In the above embodiment, the clamping fixture can constrain the position of the pressure plate and the substrate through the setting of the limit parts, so as to reduce the risk of shaking or deviation of the optical fiber array during the dispensing process, thereby ensuring that the optical fiber array is stably supported on the carrier and further improving the dispensing effect of the optical fiber array.

[0022] In some embodiments of the present application, the clamping fixture also includes a liquid stopper, which is installed on the constraint surface and is configured to stop the adhesive from flowing along a second direction when the adhesive is filled between the supporting part and the substrate. The second direction is parallel to the supporting surface and intersects with the first direction.

[0023] In the above embodiment, the liquid blocking member can not only prevent the adhesive from flowing to the parts that should not be contacted by the adhesive during the filling process, such as the outside of the optical fiber array, thereby reducing the waste of adhesive, but also stop the flow of the adhesive along the second direction, so that the shape of the adhesive after curing is more neat and beautiful.

[0024] An embodiment of the present application provides a dispensing device, which includes a dispensing mechanism and the above-mentioned clamping fixture, wherein the clamping fixture is configured to fix the optical fiber array, and the dispensing mechanism is configured to dispense glue to the optical fiber array when the clamping fixture fixes the optical fiber array.

[0025] In the aforementioned dispensing device, using the aforementioned clamping fixture, when the user drips adhesive onto the clamping fixture through the dispensing mechanism, the adhesive flows to and is contained between the substrate and the restraining portion, thereby enveloping the fiber cores held by the substrate and the pressure plate. The dispensing device utilizes the restraining portion in the clamping fixture and the substrate in the optical fiber array to restrict the shape, length, and height of the cured adhesive, thereby improving the dispensing effect of the dispensing device.

[0074] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0075] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0076] An embodiment of the present application provides a clamping fixture configured to secure an optical fiber array, a substrate of the optical fiber array, and a pressure plate of the optical fiber array, which together clamp a portion of the optical fiber array's core. The clamping fixture includes a carrier and a clamping assembly. The carrier has a carrier portion and a restraining portion connected to each other. The carrier portion is configured to support the pressure plate, and the restraining portion is configured to be spaced apart from the substrate to accommodate an adhesive for bonding the optical fiber array and a portion of the optical fiber core. The clamping assembly is configured to press the substrate toward the carrier portion when the carrier portion supports the optical fiber array.

[0077] In the aforementioned clamping jig, the user drips adhesive onto the jig, where it flows to and is contained between the substrate and the restraining portion, enveloping the fiber core held by the substrate and the pressure plate. Compared to directly applying glue to the substrate, gradually covering it with glue, the clamping jig uses the restraining portion and the substrate in the fiber array to limit the shape, length, and height of the cured adhesive. In other words, the user can adjust the spacing between the substrate and the restraining portion, as well as the length between the substrate and the restraining portion, as needed to control the shape, length, and height of the glue, thereby improving the glue dispensing effect of the fiber array.

[0078] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0079] An embodiment of the present application provides a clamping fixture 10, such as Figure 1 and Figure 5 As shown, the fixture 10 is configured to fix the optical fiber array 9, which includes a substrate 91, a fiber core 92, and a pressure plate 93. The substrate 91 and the pressure plate 93 jointly clamp a portion of the fiber core 92. In other embodiments, the fixture 10 can also be used to clamp other workpieces similar to the optical fiber array 9 for dispensing, and this application is not limited to this.

[0080] like Figure 1 and Figure 6 As shown, the clamping fixture 10 includes a carrier 11 and a clamping assembly 12. The carrier 11 has a carrier portion 111 and a constraint portion 112 connected to each other. The carrier portion 111 is configured to carry a pressure plate 93. The clamping assembly 12 is configured to press the substrate 91 in a direction toward the carrier portion 111 when the carrier portion 111 carries the optical fiber array 9.

[0081] It is understood that before dispensing glue on the optical fiber array 9, the user first places the pressing plate 93 of the optical fiber array 9 on the supporting portion 111, that is, the entire optical fiber array 9 is placed on the supporting member 11. Subsequently, the pressing assembly 12 presses the substrate 91 toward the supporting portion 111 to secure the optical fiber array 9. It should be noted that the user can be a human, a robot, a robotic arm, etc.

[0082] By setting the clamping assembly 12 and the bearing portion 111, the optical fiber array 9 can be stably fixed on the clamping fixture 10, so as to reduce the risk of shaking or offset of the optical fiber array 9 during the subsequent dispensing process, which is conducive to improving the dispensing effect of the optical fiber array 9.

[0083] In some embodiments, as Figures 6 to 9 As shown, the constraint portion 112 is configured to be spaced apart from the substrate 91 to accommodate the adhesive used to bond the optical fiber array 9. The adhesive can be a suitable adhesive such as optical fiber glue, and this application does not limit this. The fiber core 92 is partially located between the constraint portion 112 and the substrate 91. It is understandable that when the user drips adhesive onto the fixture 10, the adhesive can flow to and be accommodated between the substrate 91 and the constraint portion 112, thereby enveloping the fiber core 92 clamped by the substrate 91 and the pressure plate 93.

[0084] Compared to directly dispensing glue onto substrate 91 and gradually covering it, the fixture 10 uses the constraint 112 and substrate 91 within the optical fiber array 9 to restrict the shape, length, and height of the cured adhesive. In other words, the user can adjust the spacing between substrate 91 and constraint 112, as well as the length between them, to control the shape, length, and height of the dispensed glue, thereby improving the dispensing quality of the optical fiber array 9.

[0085] Moreover, since the adhesive is accommodated between the substrate 91 and the constraint portion 112, the substrate 91 and the constraint portion 112 can protect the cured adhesive to reduce the risk of scratching the cured adhesive by external components, so that the end face of the cured adhesive is free of scratches and indentations, thereby further improving the dispensing effect of the optical fiber array 9.

[0086] In some embodiments, the user can drip adhesive upstream of the constraint portion 112 (specifically, along the axis of the fiber core 92, on the side of the constraint portion 112 facing away from the support portion 111) to avoid adhesive covering other excess parts, wasting adhesive, and reducing the glue dripping effect. In other embodiments, the user can determine the appropriate glue dripping location based on the desired glue dispensing length.

[0087] For example, if the distance between the end face of the cured adhesive and the end face of the substrate 91 is 2 mm along the axial direction of the fiber core 92 , the user needs to select a position 2 mm away from the end face of the substrate 91 as the glue dripping position.

[0088] In some embodiments, as Figure 6 and Figure 9As shown, the bearing portion 111 has a bearing surface 1111, and the constraining portion 112 has a constraining surface 1121. The bearing surface 1111 and the constraining surface 1121 are arranged along the axis of the fiber core 92. The bearing surface 1111 is configured to support the pressure plate 93, and the constraining surface 1121 is configured to constrain the flow of the adhesive. In a direction perpendicular to the bearing surface 1111, the constraining surface 1121 is closer to the substrate 91 than the bearing surface 1111.

[0089] It should be noted that due to the surface tension characteristics and capillary action of the adhesive, by setting the constraint surface 1121 closer to the substrate 91 than the bearing surface 1111, the distance between the constraint surface 1121 and the substrate 91 can be reduced, making it easier for the adhesive to be absorbed between the constraint surface 1121 and the substrate 91, thereby facilitating more sufficient filling of the adhesive between the constraint portion 112 and the substrate 91, further improving the dispensing effect.

[0090] The first direction X is defined as being parallel to the bearing surface 1111, and the second direction Y is also parallel to the bearing surface 1111 and intersects the first direction X. The first direction X, the second direction Y, and the direction perpendicular to the bearing surface 1111 intersect with each other. The definitions of "first direction X" and "second direction Y" are provided to facilitate description of the relative positional relationship of related structures and do not necessarily imply that "first direction X" and "second direction Y" depend on the related structures involved in the above definitions. For example, the first direction X, the second direction Y, and the direction perpendicular to the bearing surface 1111 are mutually perpendicular.

[0091] In some embodiments, as Figure 6 and Figure 9 As shown, the restraining portion 112 further includes a stop surface 1122, which connects the bearing surface 1111 and the restraining surface 1121. The stop surface 1122 is configured to abut against the pressure plate 93 when the bearing surface 1111 bears the pressure plate 93, thereby preventing the pressure plate 93 from moving in the first direction X toward the restraining portion 112.

[0092] It can be understood that when the optical fiber array 9 is forced to move in the first direction X toward the restraining portion 112, the stop surface 1122 hinders the movement of the pressure plate 93, thereby restraining the position of the pressure plate 93 and, therefore, the position of the optical fiber array 9. This reduces the risk of the optical fiber array 9 shaking or shifting during the dispensing process, thereby ensuring that the optical fiber array 9 is stably supported on the carrier 11 and further improving the dispensing effect of the optical fiber array 9.

[0093] In some embodiments, the stop surface 1122 is perpendicular to the constraint surface 1121 and the bearing surface 1111 to increase the contact area of ​​the stop surface 1122 with the pressure plate 93, thereby improving the stopping effect on the pressure plate 93. In other embodiments, the stop surface 1122 may also intersect with the constraint surface 1121 and the bearing surface 1111, and this application is not limited to this.

[0094] In some embodiments, as Figure 6 and Figure 9 As shown, the constraint portion 112 further includes a guide surface 1123, which is located on the side of the constraint surface 1121 away from the support surface 1111. The adhesive can flow along the guide surface 1123 toward the constraint surface 1121 and fill the space between the support portion 111 and the substrate 91 to wrap the fiber core 92. When the adhesive drips onto the fixture 10, the adhesive flows along the guide surface 1123 toward the constraint surface 1121, that is, between the substrate 91 and the constraint surface 1121.

[0095] The guide surface 1123 allows the adhesive to flow more easily toward the restraining surface 1121 and more accurately control the adhesive flow path. This not only ensures that the adhesive only covers the portion to be bonded, but also reduces the risk of excessive or uneven adhesive application, thereby helping to better control the shape, height, and length of the cured adhesive.

[0096] In some embodiments, the guide surface 1123 and the constraint surface 1121 are coplanar, facilitating the processing and manufacturing of the carrier 11. In other embodiments, the guide surface 1123 and the constraint surface 1121 may not be coplanar. For example, the guide surface 1123 may be tilted to improve the fluidity of the adhesive, allowing the adhesive to flow more fully and quickly between the carrier plate and the base plate 91 to wrap around the optical fiber.

[0097] In some embodiments, as Figure 1 、 Figure 2 and Figure 10 As shown, the pressing assembly 12 includes a bracket 121 , a rotating member 122 and a pressing member 123 . The rotating member 122 is mounted on the bracket 121 and is configured to rotate relative to the bracket 121 around a first axis a. The first axis a is parallel to the bearing surface 1111 .

[0098] Specifically, the rotating member 122 is rotatably mounted on the bracket 121 via a bearing 126, with the rotation axis of the bearing 126 being the first axis a. The use of bearing 126 to achieve the rotational connection between the rotating member 122 and the bracket 121 not only reduces friction between the bracket 121 and the rotating member 122, preventing direct contact, thereby reducing energy loss and extending the service life of the fixture 10, but also ensures that the bracket 121 and the rotating member 122 maintain good alignment and positioning during relative rotation, thereby improving the stability and precision of the pressure applied to the optical fiber array 9.

[0099] In some embodiments, as Figure 11 As shown, the rotating member 122 is provided with a first through hole (not shown), the bracket 121 is provided with a second through hole (not shown), and a first rotating shaft (not shown) passes through the first through hole and the second through hole in sequence to achieve a rotational connection between the rotating member 122 and the bracket 121. The axis of the first rotating shaft is the first axis a. In other embodiments, the rotating member 122 and the bracket 121 may also adopt other suitable rotational connection structures, which are not limited in this application.

[0100] In some embodiments, as Figure 3 、 Figure 4 、 Figure 10 as well as Figure 12 As shown, the rotating member 122 has an operating part 1221 and an action part 1222, and the operating part 1221 and the action part 1222 are located on both sides of the first axis along a direction perpendicular to the bearing surface 1111, and the clamping member 123 is connected to the action part 1222. The operating part 1221 is configured to drive the action part 1222 to reciprocate along a direction perpendicular to the bearing surface 1111 so that the clamping member 123 presses or releases the substrate 91.

[0101] It can be understood that when it is necessary to fix the optical fiber array 9, the operating part 1221 drives the rotating part 122 to rotate around the first axis relative to the bracket 121, so that the action part 1222 moves in the direction toward the bearing surface 1111, thereby driving the clamping part 123 to press the substrate 91; when it is necessary to loosen the optical fiber array 9, the operating part 1221 drives the rotating part 122 to rotate in the opposite direction around the first axis relative to the bracket 121, so that the action part 1222 moves in the direction away from the bearing surface 1111, thereby driving the clamping part 123 to loosen the substrate 91.

[0102] It is worth noting that by arranging the action portion 1222 and the operating portion 1221 on both sides of the first axis in a direction perpendicular to the bearing surface 1111, the clamping assembly 12 can be prevented from obstructing or interfering with the user's glue dripping operation, making it easier for the user to drip the adhesive onto the loading jig, thereby improving the glue dispensing efficiency of the optical fiber array 9.

[0103] In some embodiments, as Figures 1 to 4As shown, the pressing assembly 12 further includes a pushing member 124 and an elastic member 125. The pushing member 124 is mounted on the bracket 121. The pushing member 124 is configured to drive the operating portion 1221 to move in a direction away from the substrate 91 (i.e., toward the bearing surface 1111), so that the pressing member 123 releases the substrate 91. One end of the elastic member 125 is connected to the operating portion 1221, and the other end is connected to the bracket 121. The elastic member 125 is configured to provide an elastic force to the operating portion 1221 in a direction away from the substrate 91, so that the pressing member 123 presses the substrate 91.

[0104] It should be noted that, under the action of the elastic member 125, the pressing member 123 can automatically maintain its pressure on the substrate 91 in the absence of external force. When necessary (e.g., to replace the optical fiber array 9, repair the carrier, etc.), the pushing member 124 can apply force to the operating portion 1221 to release the pressing member 123 from the substrate 91. This allows for more precise control of the pressing and releasing of the pressing member 123 from the substrate 91, ensuring the stability of the optical fiber array 9 during the dispensing process, thereby improving the efficiency and convenience of dispensing the optical fiber array 9.

[0105] In some embodiments, when it is necessary to press and hold the optical fiber array 9, the pushing member 124 moves away from the supporting surface 1111. At this point, the elastic member 125 contracts, and the operating portion 1221 moves away from the supporting surface 1111 under the elastic force of the elastic member 125, thereby driving the operating portion 1222 to move toward the supporting surface 1111. As the pushing member 124 moves away, the elastic member 125 gradually contracts under tension until the operating portion 1222 can press and hold the substrate 91, thereby pressing and holding the optical fiber array 9.

[0106] When it is necessary to release the optical fiber array 9, the pushing member 124 moves toward the bearing surface 1111, and the pushing member 124 abuts against the operating portion 1221. After the pushing member 124 abuts against the operating portion 1221, the pushing member 124 continues to move toward the bearing surface 1111. As the pushing member 124 continues to move, the pushing member 124 drives the operating portion 1221 toward the bearing surface 1111, and then drives the operating portion 1222 away from the bearing surface 1111, until the operating portion 1222 separates from the substrate 91, thereby releasing the substrate 91 and releasing the pressure on the optical fiber array 9.

[0107] It should be noted that no matter whether the pushing member 124 abuts against the operating portion 1221 or not, the elastic member 125 always remains in a stretched state, so as to provide elastic force to the operating portion 1221 .

[0108] In some embodiments, as Figures 1 to 4As shown, the elastic member 125 is a spring and the pushing member 124 is a screw. The bracket 121 is provided with a first connecting member 1212, and the operating portion 1221 is provided with a second connecting member 1223. The two ends of the spring 125 are respectively mounted on the first connecting member 1212 and the second connecting member 1223. The bracket 121 is provided with a threaded hole 1211, and the screw 124 is inserted into the threaded hole 1211. When the screw 124 is separated from the operating portion 1221, the pressing member 123 automatically maintains pressure on the substrate 91 under the elastic action of the spring 125; when the substrate 91 needs to be released, the user only needs to rotate the screw 124 and apply force to the operating portion 1221 to cause the pressing member 123 to release the substrate 91.

[0109] In other embodiments, the operating portion 1221 of the rotating member 122 may be directly driven by a motor or a cylinder to achieve pressing or releasing the substrate 91 , which is not limited in the present application.

[0110] In some embodiments, as Figure 10 and Figure 13 As shown, the pressing member 123 is rotatably connected to the rotating member 122, allowing the pressing member 123 to rotate relative to the rotating member 122 about a second axis b, wherein the second axis b is parallel to the first axis a. On the one hand, by rotatably connecting the pressing member 123 to the rotating member 122, the pressing member 123, driven by the rotating member 122, can not only reciprocate in a direction perpendicular to the bearing surface 1111 to compress or release the substrate 91, but can also rotate relative to the rotating member 122 about the second axis b to accommodate optical fiber arrays 9 of different shapes and sizes, thereby improving the adaptability and flexibility of the clamping fixture 10.

[0111] On the other hand, by rotatably connecting the clamping member 123 with the rotating member 122, the risk of the clamping member 123 and the substrate 91 in the optical fiber array 9 becoming stuck or stuck can be reduced, which is conducive to the smooth operation of the clamping fixture 10 and further improves the dispensing efficiency of the optical fiber array 9.

[0112] In some embodiments, the pressing member 123 is provided with a third through hole 1231, the acting portion 1222 is provided with a fourth through hole 1224, and a second rotating shaft (not shown) passes through the third through hole 1231 and the fourth through hole 1224 to achieve a rotational connection between the pressing member 123 and the acting portion 1222. The axis of the second rotating shaft is the second axis b.

[0113] In other embodiments, other rotating connection structures may also be used, which is not limited in this application, and those skilled in the art may choose according to actual conditions.

[0114] In some embodiments, the fixture 10 further includes a stopper (not shown), which is mounted on the bearing surface 1111 and configured to abut against the side walls of the pressure plate 93 and the side walls of the substrate 91 when the bearing portion 111 bears the pressure plate 93, thereby constraining the position of the optical fiber array 9. It should be noted that the side walls of the pressure plate 93 specifically refer to the walls of the pressure plate 93 that are perpendicular to the bearing surface 1111 and distributed along the second direction Y. The side walls of the substrate 91 specifically refer to the walls of the substrate 91 that are perpendicular to the bearing surface 1111 and distributed along the second direction Y.

[0115] It is understood that when the optical fiber array 9 is moved by force, the stopper can hinder the movement of the pressure plate 93 and the base plate 91, thereby constraining the position of the optical fiber array 9. The provision of the stopper can further reduce the risk of the optical fiber array 9 shaking or shifting during the dispensing process, improve the stability of the optical fiber array 9, and thus improve the dispensing effect of the optical fiber array 9.

[0116] In some embodiments, as Figure 6 and Figure 9 As shown, the support portion 111 is provided with two protrusions 1112 extending away from the support surface 1111, forming a position-limiting member. A groove 1113 is formed between the two protrusions 1112. The groove 1113 is configured to accommodate the optical fiber array 9. As will be understood, when the optical fiber array 9 is accommodated within the groove 1113, the sidewalls of the two protrusions 1112 facing into the groove 1113 abut against the sidewalls of the substrate 91 and the sidewalls of the pressure plate 93 in the optical fiber array 9, thereby constraining the position of the optical fiber array.

[0117] It should be noted that, by integrally forming the limiting member and the supporting member 11 , it is helpful to improve the connection strength between the limiting member and the supporting portion 111 , thereby improving the temperature resistance of the optical fiber array 9 being fixed.

[0118] In other embodiments, the limiting member may also be provided separately, for example, a limiting pin, a limiting nail, etc. may be provided separately to facilitate the disassembly and installation of the limiting member, which is not limited in this application.

[0119] In some embodiments, as Figure 9 As shown, the fixture 10 further includes a liquid stopper 13, which is mounted on the restraining surface 1121 and is configured to stop the adhesive from flowing along the second direction Y when the adhesive is filled between the carrier portion 111 and the substrate 91. The liquid stopper 13 not only prevents the adhesive from flowing to areas that should not be contacted by the adhesive during the filling process, such as the exterior of the optical fiber array 9, thereby reducing adhesive waste, but also stops the adhesive from flowing along the second direction Y, thereby ensuring a more uniform and aesthetically pleasing shape of the cured adhesive.

[0120] In some embodiments, the working principle of the clamping fixture 10 is as follows: the user first moves the pushing member 124 toward the bearing surface 1111. The pushing member 124 drives the rotating member 122 to rotate about the first axis a. The action portion 1222 moves away from the bearing surface 1111, and drives the pressing member 123 away from the bearing surface 1111. Subsequently, the user places the optical fiber array 9 on the bearing surface 1111 and drives the pushing member 124 away from the bearing surface 1111. The pushing member 124 drives the rotating member 122 to rotate in the opposite direction about the first axis a. The action portion 1222 moves toward the bearing surface 1111, and drives the pressing member 123 toward the bearing surface 1111, thereby pressing and holding the optical fiber array 9.

[0121] An embodiment of the present application provides a dispensing device 1, such as Figure 13 As shown, the dispensing device 1 includes a dispensing mechanism 20 and the aforementioned clamping fixture 10. The clamping fixture 10 is configured to secure the optical fiber array 9. The dispensing mechanism 20 is configured to dispense adhesive onto the optical fiber array 9 while the clamping fixture 10 secures the optical fiber array 9. When the user drips adhesive onto the clamping fixture 10 through the dispensing mechanism 20, the adhesive can flow to and be contained between the substrate 91 and the restraining portion 112, thereby enveloping the optical fiber core 92 clamped by the substrate 91 and the pressure plate 93.

[0122] Glue dispensing device 1 utilizes the aforementioned fixture 10. Constraints 112 within fixture 10 and substrate 91 within optical fiber array 9 restrict the shape, length, and height of the cured adhesive, thereby enhancing the dispensing efficiency of glue dispensing device 1. Furthermore, because the adhesive is contained between substrate 91 and constraint 112, substrate 91 and constraint 112 protect the cured adhesive, reducing the risk of scratches from external components. This ensures that the end face of the cured adhesive remains free of scratches and indentations, further enhancing the dispensing efficiency of glue dispensing device 1.

[0123] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of disclosure of the present application.
