Description

Technical Field

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

[0002] Gluing a PBS optical element and a silicon lens with UV glue is one of the important steps in the processing of certain optical devices. Since the silicon lens is opaque to ultraviolet light, when curing, the light source needs to be moved to the side for inclined irradiation or irradiated from the bottom of the device to the gluing interface to cure the UV glue. The disadvantages of this curing method are as follows:

[0003] 1. When the light source is inclinedly irradiated from the side to the gluing interface, the ultraviolet light power will be reduced due to the reflection loss at different incident angles. The larger the incident angle, the lower the light power transmitted to the gluing interface. The smaller the incident angle, the gluing area closer to the light source will not be irradiated by the light source, and the gluing and curing efficiency is relatively low.

[0004] 2. When the light source is irradiated from the bottom to the gluing interface, the light source needs to be fixed at the bottom of the product. Under a conventional purification bench, the product needs to be lifted to make room for installing the light source at the bottom, and the operation process is relatively inconvenient. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a silicon lens gluing and curing device, which has the advantages of specifically improving the curing efficiency, high gluing quality, and convenient operation.

[0006] The purpose of the utility model is realized by adopting the following technical solutions:

[0007] According to an embodiment of the present disclosure, a silicon lens gluing and curing device is provided, including:

[0008] A positioning jig, a placement groove is formed in the positioning jig, and positioning steps for placing and positioning the device to be cured are provided on both sides of the placement groove. The device to be cured includes a PBS optical element and a silicon lens adhesively bonded to each other with UV glue, and the PBS optical element transmits ultraviolet light;

[0009] A reflecting mirror fixed in the placement groove, the PBS optical element of the device to be cured is placed on the positioning step, and a reflection gap is formed between the PBS optical element and the reflecting mirror; and,

[0010] A curing light source suspended above the positioning jig and on both sides of the device to be cured along the extending direction of the reflecting mirror, and the emitted light beam of the curing light source can be reflected by the reflecting mirror and irradiate on the PBS optical element, and pass through the PBS optical element to cure the gluing interface.

[0011] To implement the above technical solution, during gluing, first apply UV glue between the PBS optical component and the silicon lens and bond them to each other. Then, place the device to be cured composed of the two on the positioning step. At this time, the PBS optical component is located below, and there is a reflection gap formed between it and the mirror placed in the storage groove. Set the working parameters such as the power and working duration of the curing light source, and start the curing light source so that its emitted light beam irradiates the mirror at a certain inclination angle. After the light beam is reflected, it passes through the PBS optical component and irradiates the gluing interface, thereby curing the gluing interface. After the curing is completed, just remove the bonded device. The operation process is simple and convenient, and the gluing interface can be irradiated more fully, with less energy loss and higher gluing and curing efficiency.

[0012] In some exemplary embodiments, the width of the positioning step is the same as the length of the device to be cured, the width of the mirror is the same as the width of the storage groove, and the mirror extends out of both sides of the device to be cured.

[0013] In some exemplary embodiments, a limiting groove matching the device to be cured is provided in the middle of the positioning step.

[0014] Implementing the above technical solution can place the device to be cured at a suitable position more quickly.

[0015] In some exemplary embodiments, the curing light source is inclined and arranged above the positioning jig, and the angle between the emitted light beam of the curing light source and the vertical normal is < 10°.

[0016] In some exemplary embodiments, the distance between the PBS optical component and the mirror is 3 - 10 mm.

[0017] Implementing the above technical solution, by setting reasonable dimensions and angles, the emitted light beam of the curing light source can be incident on the gluing interface at a small angle, reducing the occupied working space.

[0018] In some exemplary embodiments, the curing light source is fixed to a connecting bracket through a rotation adjustment seat, the connecting bracket is fixed to both sides of the positioning jig, and the rotation adjustment seat is used to adjust the inclination angle of the curing light source.

[0019] Implementing the above technical solution facilitates adjusting the deflection angle of the curing light source according to requirements.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in 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 shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 3 shown, an embodiment of the present invention provides a silicon lens 42 gluing and curing device, including: a positioning fixture 10, a placement groove 11 is opened in the positioning fixture 10, and positioning steps 12 for placing and positioning the device to be cured are provided on both sides of the placement groove 11. The device to be cured includes a PBS optical component 41 and a silicon lens 42 adhesively bonded to each other by UV glue, and the PBS optical component 41 transmits ultraviolet light; a mirror 20 fixed in the placement groove 11, the PBS optical component 41 of the device to be cured is placed on the positioning step 12, and a reflection gap is formed between the PBS optical component 41 and the mirror 20; and a curing light source 30 suspended above the positioning fixture 10 and located on both sides of the device to be cured along the extension direction of the mirror 20. The emitted light beam of the curing light source 30 can be reflected by the mirror 20 and irradiate on the PBS optical component 41, and pass through the PBS optical component 41 to cure the gluing interface.

[0029] Specifically, the scale of the positioning fixture 10 can be processed and formed in an integrally formed manner according to the size of the device to be cured. The mirror 20 can be directly placed in the placement groove 11 or adhesively fixed to the positioning fixture 10. Among them, the width of the positioning step 12 is the same as the length of the device to be cured, so that the device to be cured will not deflect randomly after being placed on the positioning step 12. The width of the mirror 20 is the same as the width of the placement groove 11, so that ultraviolet light can irradiate on the gluing interface as much as possible, and the mirror 20 extends out of both sides of the device to be cured. Usually, the length of the mirror 20 can be set to be the same as the length of the positioning fixture 10.

[0030] Furthermore, in some embodiments, a limiting groove 13 matching the device to be cured is provided in the middle of the positioning step 12, so that the device to be cured can be placed at a suitable position more quickly. Usually, the size of the limiting groove 13 can be slightly larger than the width of the PBS optical component 41, so that it is more convenient to pick up and place the device to be cured.

[0031] The curing light source 30 can be an existing ultraviolet curing lamp. The curing light source 30 is tilted above the positioning fixture 10, and the angle between the outgoing light beam of the curing light source 30 and the vertical normal is less than 10°. Since the width of the conventional PBS optical component 41 is between 0.5-1mm, the spacing between the PBS optical component 41 and the reflector 20 can be set to 3-10mm, which can be set according to the size of the device to be cured. Of course, in some embodiments, the spacing between the PBS optical component 41 and the reflector 20 can also be adjusted by setting structures such as pads and blocks; by setting reasonable sizes and angles, the outgoing light beam of the curing light source 30 can be incident on the bonding interface at a small angle, reducing the occupied working space.

[0032] In order to facilitate the adjustment of the deflection angle of the curing light source 30 according to needs, the curing light source 30 is fixed to a connecting bracket 32 ​​through a rotating adjustment seat 31, and the connecting bracket 32 ​​is fixed to both sides of the positioning fixture 10. The rotating adjustment seat 31 is used to adjust the inclination angle of the curing light source 30. The rotating adjustment seat 31 is rotatably connected to the curing light source 30 and can be locked and fixed by connecting parts such as pins and screws. After the curing light source 30 is adjusted to a suitable deflection angle, it can be locked by the connecting parts. The connecting bracket 32 ​​can be adjusted to be fixed on both sides of the positioning fixture 10 by welding, riveting, screw connection, etc., and can also be fixed on a workbench synchronously with the positioning fixture 10; of course, in some embodiments, a sealed shell can also be provided to prevent ultraviolet light from overflowing, and the curing light source 30 can be locked and fixed on the inner wall of the sealed shell.

[0033] During gluing, UV glue is first coated between the PBS optical component 41 and the silicon lens 42 and they are bonded to each other, and then the device to be cured composed of the two is placed on the positioning step 12. At this time, the PBS optical component 41 is located at the bottom, and a reflection gap is formed between it and the reflector 20 placed in the storage groove 11. The power, working time and other working parameters of the curing light source 30 are set, and the curing light source 30 is started so that its emitted light beam irradiates the reflector 20 at a certain inclination angle. After reflection, the light beam passes through the PBS optical component 41 and irradiates the gluing interface, so that the gluing interface can be cured. After the curing is completed, the bonded device can be removed. The operation process is simple and convenient, and the gluing interface can be irradiated more fully, with less energy loss and higher gluing and curing efficiency.

[0034] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications and improvements can be made, which are equivalent modifications and improvements made to the above embodiments based on the essential technology of the utility model, and all of them belong to the protection scope of the utility model.
