Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet curing equipment, and particularly relates to a curing box for an optical fiber loop. Background Art

[0002] The ultraviolet curing technology is a technology that uses ultraviolet rays to irradiate ultraviolet curable resins such as coatings or inks containing polymerizable polymers, photo-polymerizable monomers, and photo-initiators, so that they can be quickly cured and dried in seconds. At present, due to advantages such as fast curing speed, energy conservation and environmental protection, the ultraviolet curing technology has occupied a large market share in industries such as chemical industry, electronics, surface treatment, printing, and painting.

[0003] When curing the circular or elliptical optical fiber loop wound with UV glue and thermosetting glue, it is necessary to rotate the curing device to rotate the optical fiber loop to achieve the purpose of uniform curing of the glue at 360°. The existing optical fiber loops are mainly cured by winding them on a skeleton, and the skeleton is mainly installed on a metal shaft driven by a motor. During the curing process, the temperature of the metal shaft rises due to heat, and the heat on the metal shaft is transferred to the glue on the optical fiber loop through the skeleton, resulting in the melting and deformation of the glue, and finally the cured glue does not meet the uniformity requirements, leading to a high defective rate of the optical fiber loop. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a curing box for an optical fiber loop, which can ensure the uniformity of the glue after curing and greatly reduce the defective rate of the optical fiber loop.

[0005] The utility model is realized through the following technical solutions:

[0006] A curing box for an optical fiber loop, used for curing the optical fiber loop wound on a skeleton, includes a box body, a driving component, and an ultraviolet curing lamp fixed on the box body.

The driving component includes a motor fixed outside the box body and a main driving shaft. The main driving shaft passes through the through hole, and one end of the main driving shaft is coaxially and fixedly connected to the output shaft of the motor, and the other end is located inside the working cavity. The curing box further includes a processing shaft, a heat insulation sleeve, and a locking block arranged inside the working cavity.

The heat insulation sleeve is detachably connected to the processing shaft through the locking block, and the skeleton is sleeved on the heat insulation sleeve.

[0007] Further, a limiting block is protruded on the processing shaft. The heat insulation sleeve is sleeved on the processing shaft, and one end of the heat insulation sleeve abuts against the limiting block. The locking block is threadedly connected to the other end of the processing shaft, and the locking block abuts against the other end of the heat insulation sleeve to lock the heat insulation sleeve.

[0008] Further, the heat insulation sleeve is made of bakelite.

[0009] Further, the main drive shaft is provided with a first mating groove, one end of the processing shaft is received in the first mating groove, and a first screw hole is provided on the outer peripheral surface of the main drive shaft, and a screw passes through the first screw hole and abuts against the processing shaft.

[0010] Further, a first support frame is also fixed on the inner wall of the working chamber, and a first bearing is provided between the main drive shaft and the first support frame.

[0011] Further, the drive assembly further includes a transmission assembly and a sub-drive shaft. The sub-drive shaft is in transmission connection with the main drive shaft through the transmission assembly. The sub-drive shaft is located on one side of the main drive shaft close to the ultraviolet curing lamp, and the processing shaft is detachably connected to the sub-drive shaft.

[0015] Further, a second support frame is also fixed on the inner wall of the working chamber, and at least two second bearings are provided between the sub-drive shaft and the second support frame.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

The uniformity after the glue is cured can be ensured, and the defective rate of the optical fiber ring is greatly reduced.

[0025] The technical solution of the utility model will be further described in detail and non - restrictively below in conjunction with the preferred embodiments and their accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation of the present utility model.

[0026] As Figures 1 - 5 shown, a curing box for an optical fiber ring according to an embodiment of the present utility model is used to cure the optical fiber ring wound around a skeleton 9, and includes a box body 1, a driving assembly 2, and an ultraviolet curing lamp fixed on the box body 1. The box body 1 includes a working cavity 10, and through holes 101 are provided on the inner wall 100 of the working cavity 10. The driving assembly 2 includes a motor 20 fixed outside the box body 1 and a main driving shaft 21. The main driving shaft 21 passes through the through hole 101, and one end of the main driving shaft 21 is coaxially and fixedly connected to the output shaft of the motor 20, and the other end is located in the working cavity 10. It is characterized in that the curing box further includes a processing shaft 4, a heat insulation sleeve 5, and a locking block 6 arranged inside the working cavity 10. One end of the processing shaft 4 is detachably connected to the other end of the main driving shaft 21. The heat insulation sleeve 5 is detachably connected to the processing shaft 4 through the locking block 6. The skeleton 9 is sleeved on the heat insulation sleeve 5. By sleeving the skeleton 9 on the heat insulation sleeve 5, it is avoided that the skeleton 9 directly contacts the processing shaft 4 made of metal material, and further, the heat on the processing shaft 4 is prevented from being transferred to the glue on the optical fiber ring through the skeleton 9, resulting in the situation that the glue melts and deforms. The uniformity after the glue is cured can be ensured, and the defective rate of the optical fiber ring is greatly reduced.

[0027] A limiting block 40 protrudes on the processing shaft 4. The heat insulation sleeve 5 is sleeved on the processing shaft 4, and one end of the heat insulation sleeve 5 abuts against the limiting block 40. The locking block 6 is threadedly connected to the other end of the processing shaft 4, and the locking block 6 abuts against the other end of the heat insulation sleeve 5 to lock the heat insulation sleeve 5. In this embodiment, the material of the heat insulation sleeve 5 is bakelite.

[0028] The main drive shaft 21 is provided with a first mating groove 210. One end of the processing shaft 4 is received in the first mating groove 210, and a first screw hole 211 is provided on the outer peripheral surface of the main drive shaft 21. A screw passes through the first screw hole 211 and abuts against the processing shaft 4.

[0029] A first support frame 7 is further fixed on the inner wall 100 of the working chamber 10. A first bearing 70 is provided between the main drive shaft 21 and the first support frame 7.

[0030] The drive assembly 2 further includes a transmission assembly 22 and a secondary drive shaft 23. The secondary drive shaft 23 is drivingly connected to the main drive shaft 21 through the transmission assembly 22. The secondary drive shaft 23 is located on the side of the main drive shaft 21 close to the ultraviolet curing lamp 3. The processing shaft 4 is detachably connected to the secondary drive shaft 23. Since the secondary drive shaft 23 is closer to the ultraviolet curing lamp 3, the curing time required is shorter, while the main drive shaft 21 is relatively farther from the ultraviolet curing lamp 3, and the curing time required is relatively longer. Therefore, the user can choose to connect the processing shaft 4 to the main drive shaft 21 or the secondary drive shaft 23 according to the curing requirements. In this embodiment, for a skeleton 9 with an inner diameter of 30 - 70 mm, it is driven to rotate and cure by the main drive shaft 21, and for a skeleton 9 with an inner diameter greater than 70 mm or less than 30 mm, it is driven to rotate and cure by the secondary drive shaft 23.

[0031] The transmission assembly 22 includes a driving wheel 220, a driven wheel 221 and a synchronous belt 222. The driving wheel 220 is sleeved on the main drive shaft 21, the driven wheel 221 is sleeved on the secondary drive shaft 23, and the synchronous belt 222 is mounted between the driving wheel 220 and the driven wheel 221.

[0032] The transmission assembly 22 further includes a pressing wheel 223 and a fixing bracket 224. The fixing bracket 224 is fixed on the inner wall 100 of the working chamber 10. The pressing wheel 223 is rotatably arranged on the fixing bracket 224, and the pressing wheel 223 abuts against the synchronous belt 222. The pressing wheel 223 can make the synchronous belt 222 more taut, avoiding the situation that the rotation between the main drive shaft 21 and the secondary drive shaft 23 is asynchronous due to the slack of the synchronous belt 222.

[0033] The secondary drive shaft 23 is provided with a second mating groove 230. One end of the processing shaft 4 is received in the second mating groove 230, and a second screw hole 231 is provided on the outer peripheral surface of the secondary drive shaft 23. A screw passes through the second screw hole 231 and abuts against the processing shaft 4.

[0034] A second support frame 8 is further fixed on the inner wall 100 of the working chamber 10. At least two second bearings 80 are provided between the secondary drive shaft 23 and the second support frame 8.

[0035] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
