Detailed Embodiments

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0041] The present application provides an optical component. Figures 1 to 3 These are some embodiments of the present application.

[0042] Please refer to Figures 1 to 3 , in some embodiments of the present application, the optical component includes a substrate 1, at least one mounting groove 2 is provided on the substrate 1, at least one glue groove 3 is provided at the bottom of the mounting groove 2 of the substrate 1, and a colloid is provided in the glue groove 3; wherein, the material of the substrate 1 is not limited, and the substrate 1 can be a metal structural member, an optical element 4, a plastic structural member, etc.

[0043] The optical component further includes at least one optical element 4, the optical element 4 is disposed in the mounting groove 2, and the optical element 4 is connected to the substrate 1 through the colloid filled into the glue groove 3.

[0044] In some embodiments of the present application, the optical element 4 is fixedly connected to the substrate 1 through the colloid filled into the glue groove 3.

[0045] In the technical solution of the present application, by providing a mounting groove 2 on the substrate 1 and a glue groove 3 in the mounting groove 2, when the optical element 4 and the substrate 1 are mounted, the thickness of the colloid after molding will be limited by the depth of the glue groove 3, that is, the thickness of the colloid in the glue groove 3 is easier to control.

[0046] It can be understood that since the thickness of the colloid is controlled by the depth of the glue groove 3, the depths of the various parts of the glue groove 3 can be set to be the same or different, or the depths of multiple glue grooves 3 can be set to be the same or different according to the actual assembly requirements, so as to be applicable to different assembly schemes between the optical element 4 and the substrate 1.

[0047] In addition, the colloid located in the glue groove 3 will not be squeezed between the optical element 4 and the substrate 1, and can also avoid the deformation of the colloid caused by extrusion, thereby preventing uneven stress distribution of the colloid.

[0048] In some embodiments of the present application, at least a part of the groove wall of the mounting groove 2 is in contact with the side wall of the optical element 4; in this embodiment, it is set in this way that when the optical element 4 enters the mounting groove 2, its position will be restricted by the groove wall of the mounting groove 2, so that the optical element 4 moves along the direction from the groove opening to the groove bottom of the mounting groove 2 and is not easily displaced, thereby realizing accurate positioning of the optical element 4 when it is mounted on the substrate 1.

[0049] In some embodiments of the present application, at least one glue overflow groove 5 is further provided at the bottom of the installation groove 2 of the substrate 1, and the glue overflow groove 5 communicates with the glue groove 3; that is, in this embodiment, if there is too much colloid in the installation groove 2, when the optical element 4 is installed on the substrate 1, after the colloid fills the installation groove 2, it will overflow into the glue overflow groove 5, thus preventing the colloid from overflowing onto the contact surface between the optical element 4 and the bottom of the installation groove 2, and further affecting the assembly between the optical element 4 and the substrate 1.

[0050] It can be understood that when the colloid is in the glue groove 3 and not completely cured, it is in a semi-solidified state. Therefore, the colloid can flow along the wall of the glue groove 3. When the colloid is dispensed in the glue groove 3, the colloid will present a droplet state due to surface tension, and the height of the droplet will be higher than the depth of the glue groove 3. When the optical element 4 and the substrate 1 are assembled, the optical element 4 will squeeze the droplet until the droplet fills the glue groove 3, and the excess colloid will further overflow into the glue overflow groove 5.

[0051] In some embodiments of the present application, the number of glue grooves 3 is set to be multiple; among them, at least one glue overflow groove 5 is connected between two adjacent glue grooves 3; in this embodiment, the colloid in different glue grooves 3 can flow into each glue groove 3 through the glue overflow groove 5, making the distribution of the colloid in the multiple glue grooves 3 more uniform, and further making the stress distribution of the colloid more uniform.

[0052] In some embodiments of the present application, the optical component further includes a boss 6, and the boss 6 has an assembly surface 7. Among them, the glue groove 3 extends from the assembly surface 7 into the boss 6, and the optical element 4 is arranged on the assembly surface 7; the area of the boss 6 is smaller than the area of the bottom of the installation groove 2. The assembly surface 7 is machined on the boss 6 because if the bottom of the groove is directly machined into the assembly surface 7, there will be a problem of complex processing steps, and the area of the boss 6 is smaller than the area of the bottom of the installation groove 2 to facilitate machining on the substrate 1 to form the assembly surface 7.

[0053] In addition, as Figures 2 to 3 shown, the shape of the boss 6 located in the installation groove 2 is not limited, and it is only necessary to be adapted to the installation surface of the optical element 4; at the same time, the shape of the glue groove 3 is not limited either, and it can be circular, rectangular, triangular or an irregular shape.

[0054] In some embodiments of the present application, at least one glue overflow groove 5 is further provided on the assembly surface 7 of the boss 6, and the glue overflow groove 5 communicates with the glue groove 3; that is, in this embodiment, if there is too much colloid in the installation groove 2, when the optical element 4 is installed on the substrate 1, after the colloid fills the installation groove 2, it will overflow into the glue overflow groove 5, thus preventing the colloid from overflowing onto the contact surface between the optical element 4 and the boss 6, and further affecting the assembly between the optical element 4 and the substrate 1.

[0055] In some embodiments of the present application, the number of glue grooves 3 is set to be multiple; wherein, at least one overflow glue groove 5 is connected between two adjacent glue grooves 3; in this embodiment, the glue in different glue grooves 3 can flow into each glue groove 3 through the overflow glue groove 5, so that the distribution of the glue in the multiple glue grooves 3 is more uniform, and further the stress distribution of the glue is also more uniform.

[0056] In some embodiments of the present application, the overflow glue groove 5 communicates with the glue groove 3 and the installation groove 2; that is, in this embodiment, if there is too much glue in the glue groove 3, when the optical element 4 and the substrate 1 are installed, after the glue groove 3 is filled with glue, the glue will overflow into the overflow glue groove 5, thus avoiding the glue from overflowing onto the contact surface between the optical element 4 and the substrate 1, and further affecting the assembly between the optical element 4 and the substrate 1.

[0057] In addition, if there is still excess glue after it flows into the overflow glue groove 5, the excess glue will flow along the overflow glue groove 5 into the installation groove 2, that is, such a setting can ensure that there is sufficient safety margin for the installation between the optical element 4 and the substrate 1, and avoid too much glue in the installation groove 2 from affecting the assembly between the optical element 4 and the substrate 1.

[0058] In some embodiments of the present application, an installation hole 11 is further formed on the substrate 1, the installation hole 11 is located on one side of the installation groove 2, and the installation hole 11 is configured to install a limiting structure 9 for fixing the optical element 4.

[0059] The following are the assembly steps of the optical element 4 and the substrate 1. In an embodiment of the present application, it is described with the glue being an ultraviolet curable glue and the material of the substrate 1 being metal; wherein, the specific type of the glue is not limited, and any glue that can bond the optical element 4 and the substrate 1 in the art can be applied to the technical solution of the present application.

[0060] When the optical element 4 and the substrate 1 are adhesively assembled, with the substrate 1 as the assembly reference, glue is dispensed into the glue groove 3 of the substrate 1. After the glue dispensing is completed, the glue will present a glue drop state due to surface tension, and the height of the outer surface of the glue drop will exceed the depth of the glue groove 3. Then the optical element 4 is placed above the installation groove 2. When the optical element 4 is moved into the installation groove 2, the side wall of the optical element 4 contacts the groove wall of the installation groove 2 to achieve accurate positioning of the optical element 4. Then the optical element 4 is vertically moved down until the optical element 4 is completely fitted with the assembly surface 7 on the boss 6. At this time, the optical element 4 is assembled in place; in this situation, the glue drop is in full contact and connection with the optical element 4 and the groove wall of the installation groove 2, thus presenting a glue layer state, and the thickness of the glue layer is determined by the depth of the glue groove 3. At this time, the ultraviolet curable glue has not been cured yet, and the optical element 4 is not completely fixed to the substrate 1; at this time, the optical element 4 and the substrate 1 are fixed by the limiting structure.

[0061] Finally, the substrate 1 can be placed under an ultraviolet lamp or a handheld ultraviolet lamp and irradiated under the ultraviolet lamp for 20 s to 30 s until the ultraviolet curable adhesive cures, and the optical element 4 is preliminarily fixed to the substrate 1. It can be understood that the curing time of the ultraviolet curable adhesive is related to the power of the ultraviolet lamp. Here, the irradiation time of the ultraviolet lamp is not a fixed value and is adjusted according to the actual power of the ultraviolet lamp.

[0062] After the optical element 4 is preliminarily fixed to the substrate 1, the limiting structure can be removed from the substrate 1, and then the optical parts with the connection removed are placed under the ultraviolet lamp again for photocuring, and finally curing is obtained.

[0063] The present application also provides a pressure maintaining assembly. Figures 4 to 7 These are some embodiments of the present application.

[0064] In some embodiments of the present application, the pressure maintaining assembly includes a substrate 1. At least one mounting groove 2 for mounting an optical element 4 is provided on the substrate 1. At least one glue groove 3 is provided at the bottom of the mounting groove 2 of the substrate 1, and a colloid is provided in the glue groove 3. Among them, the substrate 1 is as described in the above embodiments. Since this pressure maintaining assembly adopts all the technical solutions of all the above embodiments related to the substrate 1, it has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0065] Please refer to Figures 4 to 7 , the pressure maintaining assembly further includes a limiting structure 9. The limiting structure 9 includes a connecting member 91 and a pressing member 92. The connecting member 91 is detachably mounted on the substrate 1; the pressing member 92 is provided on the connecting member 91; among them, the pressing member 92 has a first state and a second state. When the pressing member 92 is in the first state, the pressing member 92 can slide along the connecting member 91; when the pressing member 92 is in the second state, the pressing member 92 is fixed to the connecting member 91 and abuts against the optical element 4; among them, the number of the limiting structures 9 mounted on the substrate 1 is not limited. As Figure 4 shown, one limiting structure 9 is mounted on the substrate 1; as Figure 7 shown, two limiting structures 9 are mounted on the substrate 1, and the two limiting structures 9 respectively fix the two optical elements 4.

[0066] In this embodiment, the pressing member 92 and the substrate 1 are respectively arranged on opposite sides of the optical element 4. After the optical element 4 is assembled in the mounting groove 2, the pressing member 92 can be adjusted to be in the first state until the pressing member 92 approaches the optical element 4. At this time, the pressing member 92 is adjusted to be in the second state so that the pressing member 92 is firmly fixed to the connecting member 91 and abuts against the optical element 4. Since the connecting member 91 is also fixed to the substrate 1, the relative positions of the pressing member 92 and the substrate 1 are fixed, thereby restricting the movement of the optical element 4 on the substrate 1 before the colloid is completely cured to improve the assembly effect of the optical element 4 and the substrate 1.

[0067] It can be understood that since the connecting member 91 is detachably connected to the substrate 1, when the optical element 4 has not been placed in the installation groove 2, the connecting member 91 is detached from the substrate 1 to avoid interference with the installation of the optical element 4 on the installation groove 2. After the optical element 4 is placed in the installation groove 2, the connecting member 91 is installed on the substrate 1, and then the limiting of the optical element 4 is realized through the pressing member 92.

[0068] Among them, the form of the detachable connection between the connecting member 91 and the substrate 1 is not limited, and it can be a snap connection or a screw connection. In an embodiment of the present application, a mounting hole 11 is provided on the substrate 1, the mounting hole 11 is a threaded hole, and an external thread is provided at the lower end of the connecting member 91, and the external thread on the connecting member 91 matches the internal thread of the mounting hole 11 on the substrate 1.

[0069] In some embodiments of the present application, the pressing member 92 includes a main body portion 921 and a clamping portion 922. The clamping portion 922 includes two sub-clamping portions 9221. The two sub-clamping portions 9221 are both provided at the same end of the main body portion 921, and a gap 8 is formed between the two sub-clamping portions 9221 at intervals; wherein, a part of the connecting member 91 is located in the gap 8, and the two sub-clamping portions 9221 clamp the outer peripheral surface of the connecting member 91; that is, in this embodiment, the two sub-clamping portions 9221 clamp the connecting member 91, so when the pressing member 92 is in the first state, the pressing member 92 can move close to the optical element 4 along the extending direction of the connecting member 91.

[0070] Among them, the form of the fixation between the two sub-clamping portions 9221 and the connecting member 91 is not limited. In one embodiment, when the pressing member 92 is in the second state, the frictional force between the two sub-clamping portions 9221 and the connecting member 91 is greater than the gravity of the pressing member 92, so that the pressing member 92 and the connecting member 91 are relatively fixed. At this time, to make the pressing member 92 move, an external force greater than the frictional force between the two sub-clamping portions 9221 and the connecting member 91 needs to be applied, so that the pressing member 92 moves along the connecting member 91 and is in the first state; in another embodiment, the clamping force of the two sub-clamping portions 9221 clamping the connecting member 91 can be adjusted by other parts to realize the conversion of the pressing member 92 between the first state and the second state.

[0071] In some embodiments of the present application, at least one sub-clamping portion 9221 has elasticity; that is, in this embodiment, the elasticity of the sub-clamping portion 9221 can be utilized to increase the frictional force between the sub-clamping portion 9221 and the connecting member 91, thereby realizing the relative fixation between the pressing member 92 and the connecting member 91.

[0072] To improve the reliability of the fixation between the pressing member 92 and the connecting member 91, in an embodiment of the present application, two sub-clamping portions 9221 are provided and both have elasticity.

[0073] In some embodiments of the present application, the limiting structure 9 further includes a fastener 923. The fastener 923 connects one ends of the two sub-clamping portions 9221 away from the main body portion 921 to adjust the fastening degree between the two sub-clamping portions 9221 and the connecting member 91; that is, by connecting the two sub-clamping portions 9221 with the fastener 923 and making the gap between the two sub-clamping portions 9221 smaller, so that the fixation between the pressing member 92 and the connecting member 91 is reliable.

[0074] In addition, to ensure that the two sub-clamping portions 9221 will not break when the fastener 923 is tightened and to ensure a better fixation effect between the two sub-clamping portions 9221 and the connecting member 91, in an embodiment of the present application, the two sub-clamping portions 9221 both have elasticity.

[0075] Among them, the specific structure of the fastener 923 is not limited, and it can be a bolt or a buckle. In some embodiments of the present application, the fastener 923 is a bolt; that is, by screwing the bolt, the tightness between the two sub-clamping portions 9221 and the connecting member 91 is adjusted, so as to realize the switching between the first state and the second state of the pressing member 92.

[0076] In some embodiments of the present application, at least one sub-clamping portion 9221 is provided with a receiving groove 10 on a side close to the other sub-clamping portion 9221. The receiving groove 10 is used to accommodate at least part of the main body portion 921; by providing the receiving groove 10, the groove shape of the receiving groove 10 matches the outer shape of the connecting member 91, so that the pressing member 92 will not generate displacement in other directions when moving along the extending direction of the connecting member 91.

[0077] In some embodiments of the present application, the pressing member 92 further includes a contact portion 924, and the contact portion 924 is movably arranged on the main body portion 921; among them, the contact portion 924 can move towards the direction close to the optical element 4 to contact the side of the optical element 4 facing away from the substrate 1; that is, in this embodiment, after the main body portion 921 moves close to the optical element 4, to ensure reliable contact between the pressing member 92 and the optical element 4, the contact force of the pressing member 92 on the optical element 4 can be further increased by moving the contact member, so as to avoid loosening between the optical element 4 and the substrate 1.

[0078] In an embodiment of the present application, a threaded hole 12 is formed in the main body portion 921, and the contact portion 924 is a setscrew, and the setscrew is screwed in the threaded hole 12; among them, to avoid damage to the optical element 4 when the setscrew limits the optical element 4, an elastic material is further provided at one end of the setscrew close to the optical element 4, and the elastic material can be plastic, rubber, etc.

[0079] The following are the assembly steps of the optical element 4 and the substrate 1. In an embodiment of the present application, it is described with the colloid being an ultraviolet curable adhesive and the material of the substrate 1 being metal; wherein, the specific type of the colloid is not limited, and any colloid that can bond the optical element 4 and the substrate 1 in the art can be applied to the technical solution of the present application.

[0080] When the optical element 4 and the substrate 1 are adhesively assembled, with the substrate 1 as the assembly reference, glue is dispensed into the glue groove 3 of the substrate 1. After the glue dispensing is completed, the colloid will present a glue drop state due to surface tension, and the height of the outer surface of the glue drop will exceed the depth of the glue groove 3. Then, the optical element 4 is placed above the installation groove 2. When the optical element 4 is moved into the installation groove 2, the side wall of the optical element 4 contacts the groove wall of the installation groove 2 to achieve accurate positioning of the optical element 4, and then the optical element 4 is vertically moved down until the optical element 4 is assembled into the installation groove 2; in this situation, the glue drop is in full contact connection with the optical element 4 and the groove wall of the installation groove 2, thus presenting a glue layer state, and the thickness of the glue layer is determined by the depth of the glue groove 3. At this time, the ultraviolet curable adhesive has not been cured yet, and the optical element 4 is not completely fixed to the substrate 1.

[0081] Secondly, the connecting member 91 is installed on the substrate 1, and the height and rotation angle of the pressing member 92 on the connecting member 91 are adjusted. At this time, the pressing member 92 is in the first state until the abutting member is directly above the optical element 4. The connecting member 91 and the pressing member 92 are relatively fixed by locking the fastening member 923, and the abutting portion 924 is moved down through the movable abutting portion 924 until it abuts against the optical element 4.

[0082] Finally, the substrate 1 can be placed under an ultraviolet lamp, or a handheld ultraviolet lamp can be used. It is irradiated under the ultraviolet lamp for 20 s to 30 s until the ultraviolet curable adhesive is cured, and the optical element 4 and the substrate 1 are preliminarily fixed. It can be understood that the curing time of the ultraviolet curable adhesive is related to the power of the ultraviolet lamp. Here, the irradiation time of the ultraviolet lamp is not a fixed value and is adjusted according to the actual power of the ultraviolet lamp.

[0083] After the optical element 4 and the substrate 1 are preliminarily fixed, the connecting member 91 can be removed from the substrate 1, and then the removed optical member is placed under the ultraviolet lamp again for photocuring, and then final curing is obtained.

[0084] The present application also proposes an optical device, including a pressure maintaining component. The pressure maintaining component is as described in the above embodiment. Since this optical device adopts all the technical solutions of all the above embodiments related to the pressure maintaining component, it has at least the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
