Description

Technical Field

[0001] The utility model relates to the technical field of curing furnaces, and specifically, to an optical fiber curing furnace. Background Art

[0002] An optical fiber curing furnace is a device used for curing the coating layer of an optical fiber during optical fiber manufacturing. When it works, after the optical fiber is dispensed with glue, the glue on the surface of the optical fiber is heated and cured to reduce the possibility of the glue flowing and deforming.

[0003] The existing optical fiber curing furnace works as follows: after the optical fiber and the joint on the fixture plate are dispensed with glue, the fixture plate with the optical fiber is horizontally placed in the upper slot of the curing furnace, and then the glue on the optical fiber is heated and cured.

[0004] Although this can achieve the heating and curing of the glue, there are still the following problems: since the optical fiber and the fixture plate are horizontally placed above the curing furnace for heating, under the action of the self-gravity of the glue, it may cause the volume of the glue near the curing furnace side to be larger than the volume of the glue far from the curing furnace side. This not only makes the shape of the cured glue uneven and unsightly, but also affects the connection between the optical fiber and the joint. Summary of the Utility Model

[0005] The utility model provides an optical fiber curing furnace, which solves the problem that the glue is prone to deformation during the curing process in the prior art and improves the practicability of the device.

[0006] The technical solution of the utility model is as follows:

[0007] An optical fiber curing furnace includes a curing furnace body.

[0008] The outer surface of the curing furnace body is of a cuboid structure. A plurality of mounting parts are fixed on the side wall of the curing furnace body. Mounting grooves are provided on the mounting parts. A fixture plate is inserted into the mounting grooves. A fixing structure for fixing the optical fiber is provided on the fixture plate. Heating sheets are provided in the mounting grooves.

[0009] The fixing structure includes a first bonding layer and a second bonding layer fixedly arranged on the mounting part. The first bonding layer is arranged between a first limiting part and a second limiting part. The second bonding layer is arranged on the side of the second limiting part away from the first limiting part. Both the first bonding layer and the second bonding layer are made of glue materials.

[0010] Further, the fixture plate includes a curing part. A first limiting part is provided at the upper end of the curing part. A second limiting part is provided at the upper end of the first limiting part. Both the first limiting part and the second limiting part are rectangular structures. The projection plane of the first limiting part in the vertical direction falls within the projection plane of the second limiting part in the vertical direction. The projection plane of the curing part in the vertical direction falls within the projection plane of the first limiting part in the vertical direction. First guiding inclined surfaces are provided on both sides of the first limiting part close to the curing part. Second guiding inclined surfaces are provided on both sides of the second limiting part close to the first limiting part. A number of first placement grooves are provided on the second limiting part. The cross-section of the first placement groove is a square structure.

[0011] Further, a number of second placement grooves are provided on the side of the curing part close to the first limiting part. The second placement grooves correspond to the first placement grooves one by one. A third placement groove is provided on the side of the second placement groove away from the first limiting part. The cross-sections of both the second placement groove and the third placement groove are arc-shaped structures. The diameter of the third placement groove is smaller than that of the second placement groove.

[0012] Further, a rotating block is fixed on the mounting member. A rotating groove is provided on the limiting member. The rotating block is rotatably connected to the rotating groove. An abutting block is also fixed on the limiting member. The abutting block is made of rubber material. The abutting block abuts against the mounting groove.

[0013] Further, the connecting structure includes a first limiting block and a second limiting block fixedly arranged on both sides of the mounting member. The cross-sections of both the first limiting block and the second limiting block are "L"-shaped structures. First magnets are fixed on both the first limiting block and the second limiting block. A second magnet is fixed on the side of the limiting member close to the first magnet. The first magnet and the second magnet have opposite magnetic polarities.

[0014] Further, the fixing structure includes a first adhesive layer and a second adhesive layer fixedly arranged on the mounting member. The first adhesive layer is arranged between the first limiting part and the second limiting part. The second adhesive layer is arranged on the side of the second limiting part away from the first limiting part. Both the first adhesive layer and the second adhesive layer are made of glue material.

[0015] Further, a buffer layer is provided at the notch of the mounting groove. The end of the limiting part close to the curing part abuts against the buffer layer. A temperature control panel is also fixed on the curing furnace body. The temperature control panel is connected to the heating sheet.

[0016] The working principle and beneficial effects of the present utility model are as follows:

[0017] Working process of this embodiment: First, rotate the limiting member and move it closer to the mounting member so that the first magnet attracts and holds the second magnet tightly. Then, insert the curing part on the fixture plate with the optical fiber into the placement groove. At this time, raise the temperature of the heating sheet through the temperature control panel to heat and cure the colloid on the optical fiber. After the curing is completed, rotate the limiting member away from the mounting member and remove the fixture plate.

[0018] In this embodiment, a mounting member is provided on the side wall of the curing furnace body, and a limiting member is rotatably provided on the mounting member. The separation or connection and fixation of the limiting member and the rotating member are realized through the connection structure, so that the fixture plate in the placement groove of the mounting member can be mounted or disassembled on the mounting member. This embodiment replaces the design of inserting the fixture plate above the curing furnace body in the prior art. By vertically placing the optical fiber, the deviation of the colloid on the optical fiber in the horizontal direction during the curing process is reduced, making the colloid formed after curing more uniform and beautiful, and the connection between the optical fiber and the connector through the colloid is more stable and reliable.

Detailed implementation mode

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] As Figures 2 to 6 shown, this embodiment proposes an optical fiber curing furnace, the structure of which includes a curing furnace body 1. The outer surface of the curing furnace body 1 in this embodiment is a cuboid structure, and a plurality of mounting parts 2 are fixedly arranged on the side wall of the curing furnace body 1. A mounting groove 24 is arranged on the mounting part 2, and a jig plate 5 is inserted into the mounting groove 24. A fixing structure is arranged on the jig plate 5 for fixing the optical fiber. A heating sheet 25 is arranged in the mounting groove 24, and a limiting part 3 is rotatably connected to one end of the mounting part 2. A connecting structure is arranged at the other end of the mounting part 2 for connecting and fixing with the limiting part 3. The fixing structure includes a first adhesive layer 512 and a second adhesive layer 513, both of which are fixedly arranged on the mounting part 2. The first adhesive layer 512 is arranged between a first limiting part 52 and a second limiting part 51, and the second adhesive layer 513 is arranged on the side of the second limiting part 51 away from the first limiting part 52. Both the first adhesive layer 512 and the second adhesive layer 513 are made of glue materials. The design of the first adhesive layer 512 and the second adhesive layer 513 in this embodiment ensures the fixed installation and convenient disassembly of the optical fiber and the mounting part 2, and ensures that the optical fiber will not be displaced when placed on the mounting part 2.

[0030] The fixture plate 5 in this embodiment includes a first guiding inclined surface 521 of the curing part. The first limiting part 52 is arranged at the upper end of the first guiding inclined surface 521 of the curing part. The second limiting part 51 is arranged at the upper end of the first limiting part 52. Both the first limiting part 52 and the second limiting part 51 are rectangular structures. The projection plane of the first limiting part 52 in the vertical direction falls within the projection plane of the second limiting part 51 in the vertical direction, which is used to place the first limiting part 52 to ensure that the position of the first limiting part 52 will not be offset. The projection plane of the first guiding inclined surface 521 of the curing part in the vertical direction falls within the projection plane of the first limiting part 52 in the vertical direction, which is used to ensure that the position of the first guiding inclined surface 521 of the curing part will not be offset. The first guiding inclined surfaces are arranged on both sides of the first limiting part 52 close to the first guiding inclined surface 521 of the curing part, which is used to make it easier for the first limiting part 52 to enter the installation groove 24 and ensure that the first limiting part 52 is not easily offset. The second guiding inclined surfaces 514 are arranged on both sides of the second limiting part 51 close to the first limiting part 52, which is used to make it easier for the first guiding inclined surface 521 of the curing part to enter the installation groove 24 and ensure that the first guiding inclined surface 521 of the curing part is not easily offset. A number of first placement grooves 511 are arranged on the second limiting part 51. The cross-section of the first placement groove 511 is a square structure, which is used to place and restrict the position of the optical fiber. Such a design ensures that the fixture plate 5 can be smoothly inserted into the installation groove 24 and ensures that the fixture plate 5 is not easily offset. The cooperation between the fixture plate 5 and the installation groove 24 is closer and it is not easily offset.

[0031] A number of second placement grooves 531 in this embodiment are arranged on the side of the first guiding inclined surface 521 of the curing part close to the first limiting part 52. The second placement grooves 531 correspond to the first placement grooves 511 one by one. The third placement grooves 532 are arranged on the side of the second placement grooves 531 away from the first limiting part 52. The cross-sections of both the second placement grooves 531 and the third placement grooves 532 are arc-shaped structures, which are used to cooperate with the connector for placement. The diameter of the third placement groove 532 is smaller than that of the second placement groove 531. Both the second placement grooves 531 and the third placement grooves 532 in this embodiment are used to place the connector to prevent the connector from detaching from the fixture plate 5.

[0032] The connection structure in this embodiment includes a first limiting block 22 and a second limiting block 23, which are both fixedly arranged on both sides of the installation part 2. The cross-sections of both the first limiting block 22 and the second limiting block 23 are "L"-shaped structures, which are used to abut against the first guiding inclined surface to ensure that the fixture plate 5 will not be offset during installation. The first magnet 221 is fixedly arranged on the first limiting block 22 and the second limiting block 23. The second magnet 32 is arranged on the side of the limiting part 3 close to the first magnet 221. The first magnet 221 and the second magnet 32 have opposite magnetic polarities. Such a design not only ensures that the limiting part 3 can be tightly attached to the fixed installation part 2 to ensure that the fixture plate 5 is not easily detached from the installation groove 24, but also enables the fixture plate 5 to be smoothly taken out after the limiting part 3 rotates away from the installation part 2.

[0033] The rotating block 21 in this embodiment is fixedly arranged on the mounting member 2, the rotating groove 31 is arranged on the limiting member 3, the rotating block 21 is rotatably connected with the rotating groove 31, the abutting block is fixedly arranged on the limiting member 3, the abutting block is made of rubber material, and the abutting block abuts against the mounting groove 24. Such a design ensures that when the limiting member 3 rotates to be close to the mounting member 2, the abutting block can abut against the clamp plate 5, ensuring that the clamp plate 5 will not be separated from the mounting groove 24.

[0034] The buffer layer in this embodiment is arranged at the notch of the installation groove 24, and the end of the limiting portion close to the first guiding inclined surface 521 of the curing portion abuts against the buffer layer to reduce the collision between the notch of the installation groove 24 and the fixture plate 5, and reduce the collision damage between the fixture plate 5 and the notch of the installation groove 24. The temperature control panel 4 is fixedly arranged on the curing furnace body 1, and the temperature control panel 4 is connected to the heating plate 25 to facilitate the control of the temperature of the heating plate 25 to meet the curing requirements of different colloids.

[0035] The working process of this embodiment is as follows: first, the limiting member 3 is rotated and brought close to the mounting member 2, so that the first magnet 221 attracts the second magnet 32, and then the first guiding slope 521 of the curing part on the clamp plate 5 equipped with the optical fiber is inserted into the placement groove. At this time, the temperature of the heating plate 25 is increased through the temperature control panel 4, so that the colloid on the optical fiber is heated and cured. After the curing is completed, the limiting member 3 is rotated away from the mounting member 2, and the clamp plate 5 is taken out.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
