Description

Technical Field

[0001] The utility model relates to the technical field of optical element processing, in particular to an optical element gluing and curing device. Background Art

[0002] Optical components are typically bonded together using optical glue, which is then cured by UV light to ensure a secure connection. However, current methods for curing optical components typically involve using a point light source in air, which has the following drawbacks:

[0003] 1. When curing anaerobic adhesives such as UT20 glue, the glue at the edge of the optical component will be in an aerobic environment and difficult to cure, resulting in uneven and insufficient curing. The cured optical component is prone to debonding, resulting in a low product yield.

[0004] 2. When using a point light source for single-point irradiation, there will be a time difference in the curing of the glue when curing large optical components, which may easily lead to glue delamination and affect the performance of the optical components;

[0005] 3. When gluing and curing optically coated glass with low UV transmittance, it is necessary to manually select a direction with higher UV transmittance for irradiation. The adjustment process is cumbersome, resulting in low production efficiency and difficulty in ensuring curing uniformity. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the present invention aims to provide an optical element gluing and curing device, which has the advantages of easy operation, high curing efficiency and good uniformity.

[0007] The purpose of this utility model is achieved by the following technical solutions:

[0008] According to an embodiment of the present disclosure, there is provided an optical element gluing and curing device, comprising:

[0009] A box body, wherein a receiving cavity for placing the optical element to be cured is formed in the box body, and a door that can be opened and closed is provided on the front side of the box body;

[0010] a nitrogen pipe connected to the box, the nitrogen pipe being used to connect to a nitrogen generator to inject nitrogen into the box and exhaust the air in the box; and

[0011] At least three groups of UV light sources are respectively arranged on three different surfaces of the box body. The box body is provided with a mounting port adapted to the UV light source. The UV light source is installed in the mounting port to emit UV light to irradiate the optical element to be cured for curing.

[0012] To implement the above technical solution, when in use, the optical device to be cured is placed in the accommodating chamber, and after the box door is closed, nitrogen is injected into the box through the nitrogen pipe by the nitrogen generator, so that the nitrogen fills the box and the air in the box is discharged. At this time, a basically oxygen-free environment is formed in the box. Then, according to the structure and process requirements of the optical element and the ultraviolet transmittance of the optical element in all directions, the corresponding UV light source is selectively turned on and the irradiation time is set. Since the UV light source is set on different surfaces of the box, it can basically meet the irradiation requirements in all directions. When the irradiation time is over, the UV light source is automatically turned off, and the nitrogen generator is turned off at this time to stop supplying nitrogen. The whole operation process is simple and convenient, with low requirements for operators, which can simplify the entire curing process and thus improve processing efficiency. Since the curing is carried out in an oxygen-free environment, the optical component can be fully cured in all directions, which improves the uniformity of curing, reduces the debonding of the optical component after curing, and improves the product yield. The large-format UV light source is used, and single-sided or multi-sided irradiation can be performed simultaneously according to needs. Therefore, the glue of each part of the optical component can be cured synchronously without the glue stratification phenomenon, thus ensuring the stability of the optical component performance.

[0013] In some exemplary embodiments, the UV light sources are provided in three groups, and are respectively disposed on the left side, the right side, and the top side of the box.

[0014] The implementation of the above technical solution can meet the illumination requirements of optical elements in different directions.

[0015] In some exemplary embodiments, an air intake control valve is provided on the nitrogen pipe to control the opening and closing of the air intake pipe.

[0016] By implementing the above technical solution, the nitrogen supply can be more conveniently controlled through the air intake control valve.

[0017] In some exemplary embodiments, the box body is further connected to an exhaust pipe, and the exhaust pipe is provided with an exhaust control valve.

[0018] To implement the above technical solution, when nitrogen is introduced, the exhaust control valve is opened to allow the air in the box to be discharged from the exhaust pipe. When the air is basically discharged, the intake control valve and the exhaust control valve can be closed, thereby saving nitrogen consumption.

[0019] In some exemplary embodiments, the nitrogen pipe is disposed on the upper side of the box body near the box door, and the exhaust pipe is disposed on the rear side of the box body near the bottom.

[0020] To implement the above technical solution, nitrogen is supplied from the top of the box, squeezing the air downward and finally discharged from the exhaust pipe, so that the air can be removed more thoroughly.

[0021] In some exemplary embodiments, the size of the light distribution area of the UV light source is (100-180) mm*(80-140) mm.

[0022] To implement the above technical solution, since the current size of the largest optical component is no larger than 60*60mm, the curing requirements of the largest-sized light source component can be met by setting an appropriate light distribution area size.

[0023] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0024] An embodiment of the present utility model provides an optical element gluing and curing device, comprising: a box body, wherein a accommodating cavity for placing an optical element to be cured is formed in the box body, and a front side of the box body is provided with an openable and closable box door; a nitrogen pipe connected to the box body, wherein the nitrogen pipe is used to connect to a nitrogen generating device to inject nitrogen into the box body and exhaust the air in the box body; and at least three groups of UV light sources respectively arranged on three different surfaces of the box body, wherein the box body is provided with a mounting port adapted to the UV light source, and the UV light source is installed in the mounting port to emit UV light to irradiate the optical element to be cured for curing. When in use, place the optical device to be cured in the accommodating chamber, close the box door, and then inject nitrogen into the box through the nitrogen pipe from the nitrogen generator, so that the nitrogen fills the box and the air in the box is discharged. At this time, a basically oxygen-free environment is formed in the box. Then, according to the structure and process requirements of the optical component and the ultraviolet transmittance of the optical component in all directions, the corresponding UV light source is selectively turned on and the irradiation time is set. Since the UV light source is set on different surfaces of the box, it can basically meet the irradiation requirements in all directions. When the irradiation time is over, the UV light source is automatically turned off. At this time, the nitrogen generator is turned off to stop supplying nitrogen. Open the box door and take out the cured optical component. The overall operation process is simple and convenient, with low requirements for operators, which can simplify the entire curing process and thus improve processing efficiency. Since the curing is carried out in an oxygen-free environment, the optical component can be fully cured in all directions, which improves the uniformity of curing, reduces the debonding of the optical component after curing, and improves the product yield. The use of a large-format UV light source and the ability to irradiate one or more sides simultaneously as needed can ensure that the glue in each part of the optical component is cured synchronously without glue stratification, thus ensuring the stability of the optical component performance.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 and Figure 2 As shown, the utility model provides an optical element gluing and curing device, comprising: a box body 10, a receiving cavity 11 for placing an optical element to be cured is formed in the box body 10, and a front side of the box body 10 is provided with an openable and closable box door 12; a nitrogen pipe 20 connected to the box body 10, the nitrogen pipe 20 is used to connect to a nitrogen generator to inject nitrogen into the box body 10 and exhaust the air in the box body 10; and at least three groups of UV light sources 30 are respectively arranged on three different surfaces of the box body 10, and a mounting port 13 adapted for the UV light source 30 is opened on the box body 10, and the UV light source 30 is installed in the mounting port 13 to emit UV light to irradiate the optical element to be cured for curing.

[0031] Specifically, the box body 10 and the box door 12 can be made of metal materials such as stainless steel and aluminum alloy, and magnetic parts that attract each other can be set between the box body 10 and the box door 12 to ensure the stability of the box door 12 when it is closed. Of course, in some embodiments, an elastic snap-fit structure can also be used to achieve the closure of the box door 12 and the box body 10. At the same time, a sealing ring can be set between the box door 12 and the box body 10 to improve the sealing between the box body 10 and the box door 12 and reduce nitrogen leakage.

[0032] In this embodiment, the UV light source 30 is fixed to the box body 10 by screw fastening. Three groups of UV light sources 30 are provided, and are respectively provided on the left side, right side and upper side of the box body 10, so as to meet the irradiation requirements of the optical elements in different directions. Of course, the UV light source 30 can also be provided on the box door 12 and the rear side of the box body 10 at the same time, and the size of the light distribution area of the UV light source 30 is (100~180)mm*(80~140)mm. Since the size of the largest optical element at present is not greater than 60*60mm, by setting a suitable light distribution area size, the curing requirements of the largest size light source element can be met.

[0033] The nitrogen generating device can be an existing device. An intake control valve 21 is provided on the nitrogen pipe 20 to control the on-off of the intake pipe. The intake control valve 21 can be an electromagnetic valve. The intake control valve 21 can more conveniently control the nitrogen supply.

[0034] In some exemplary embodiments, the housing 10 is further connected to an exhaust pipe 40, which is provided with an exhaust control valve 41. Exhaust control valve 41 can also be a solenoid valve. When nitrogen is introduced, exhaust control valve 41 is opened, allowing air within the housing 10 to be discharged from exhaust pipe 40. Once the air is substantially discharged, intake control valve 21 and exhaust control valve 41 can be closed, thereby conserving nitrogen. Furthermore, in this embodiment, nitrogen pipe 20 is positioned at the upper side of the housing 10, near door 12, and exhaust pipe 40 is positioned at the rear side of the housing 10, near the bottom. Nitrogen is supplied from the top of the housing 10, pushing the air downward, and finally being discharged from exhaust pipe 40, allowing the air to be discharged more thoroughly.

[0035] In order to facilitate the placement of the optical element to be fixed, in some embodiments, a positioning carrier can be further provided in the box 10 , and the positioning carrier can also be configured to be rotatable so as to adjust the direction of the optical element when placing it.

[0036] During use, the optical device to be cured is placed in the accommodating chamber 11, and after the box door 12 is closed, nitrogen is injected into the box body 10 through the nitrogen pipe 20 by the nitrogen generator, so that the nitrogen fills the box body 10 and the air in the box body 10 is discharged. At this time, a basically oxygen-free environment is formed in the box body 10. Then, according to the structure and process requirements of the optical element and the ultraviolet transmittance of the optical element in all directions, the corresponding UV light source 30 is selectively turned on and the irradiation time is set. Since the UV light source 30 is arranged on different surfaces of the box body 10, it can basically meet the irradiation requirements in all directions. When the irradiation time is over, the UV light source 30 is automatically turned off, and the nitrogen generator is turned off at this time. When the nitrogen supply is stopped, the box door 12 can be opened to take out the cured optical element. The overall operation process is simple and convenient, and the requirements for operators are low, thereby simplifying the entire curing process and improving processing efficiency. Since the curing is carried out in an oxygen-free environment, all directions of the optical element can be fully cured, which improves the uniformity of curing, reduces the debonding of the optical element after curing, and improves the product yield. A large-format UV light source 30 is used, and single-sided or multi-sided irradiation can be performed simultaneously according to needs. Therefore, the glue in each part of the optical element can be cured synchronously without the occurrence of glue stratification, thereby ensuring the stability of the performance of the optical element.

[0037] The above embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the spirit of the present invention. These modifications and improvements are equivalent to those made to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
