Description

Technical Field

[0001] This utility model relates to the technical field of optical mirror assembly accessories, specifically a support structure for an optical mirror. Background Technology

[0002] The assembly method of the reflector in the reflective optical imaging system is to install the optical reflector onto the reflector bracket. Usually, the reflector bracket reinforcement plate is used to make holes to leave a curing area for the glue, so that the glue in the reserved holes can be irradiated by UV light. After the glue has cured, the reflector is fixed to the reflector bracket as a whole.

[0003] The following factors contribute to the above assembly method:

[0004] ① The UV curing area of ​​the reflector adhesive is small; ② The small adhesive application area of ​​the reflector adhesive results in weak bonding force between the reflector and the reflector bracket and inconvenient operation.

[0005] The assembly efficiency of the reflector is limited by the above reasons, so we propose a support structure for the optical reflector. Utility Model Content

[0008] The tooling base has an installation groove in the middle, a reflector bracket is inserted into the installation groove, a reflector is installed on the top of the reflector bracket, and a filling gap is reserved between the reflector bracket and the reflector.

[0009] The reflector bracket has an inverted U-shaped structure, and the mounting groove matches the shape of the reflector bracket; the gaps are filled with UV glue.

[0010] The left and right outer walls of the reflector bracket are fitted with elastic locking mechanisms between them and the mounting groove.

[0011] Preferably, the elastic locking mechanism includes a locking rib installed in the tooling base and an arc-shaped clamping groove opened on the reflector bracket, with the locking rib inserted inward into the arc-shaped clamping groove.

[0012] Preferably, a sliding rod is installed on the side of the locking ridge closest to the tooling base, and multiple shock-absorbing springs are installed on the side of the sliding rod away from the locking ridge, with the shock-absorbing springs installed inside the tooling base.

[0013] Preferably, the damping spring pushes the locking rib inward, so that the locking rib is inserted into the arc-shaped clamping groove to complete the limiting and fixing of the reflector bracket; the sliding rod is responsible for assisting the sliding of the locking rib and connecting the locking rib and the damping spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] ①Dispensing area: The area of ​​the dispensing point is improved to the area of ​​the surface, which effectively increases the bonding area of ​​the UV adhesive.

[0016] ② Curing area: The curing area is improved from a point to a surface, effectively increasing the area exposed to ultraviolet light.

[0017] ③ Adhesive thrust: The adhesive area at two points is optimized and improved to the adhesive area of ​​the entire surface, effectively increasing the overall thrust by 2.5 times.

[0018] ④ Transparent Coating: The reflector is equipped with a transparent coating to enhance the intensity of the irradiated ultraviolet light.

[0026] Example:

[0027] Please see Figure 1-4 The present invention provides the following technical solution:

[0028] A support structure for an optical mirror includes a tooling base 1 and a mirror bracket 3;

[0029] The tooling base 1 has a mounting groove 2 in the middle, and a reflector bracket 3 is inserted into the mounting groove 2. The reflector bracket 3 has an inverted U-shaped structure, and the shape of the mounting groove 2 matches that of the reflector bracket 3.

[0030] A reflector 4 is installed on the top of the reflector bracket 3, and a filling gap 5 is reserved between the reflector bracket 3 and the reflector 4, which is filled with UV glue.

[0031] An elastic locking mechanism is installed between the outer walls of the left and right sides of the reflector bracket 3 and the mounting groove 2. The elastic locking mechanism includes a locking ridge 7 installed in the tooling base 1 and an arc-shaped clamping groove 9 opened on the reflector bracket 3. The locking ridge 7 is inserted into the arc-shaped clamping groove 9.

[0032] A sliding rod 6 is installed on the side of the locking rib 7 closest to the tooling base 1, and multiple shock-absorbing springs 8 are installed on the side of the sliding rod 6 away from the locking rib 7. The shock-absorbing springs 8 are installed inside the tooling base 1. The shock-absorbing springs 8 push the locking rib 7 inward, so that the locking rib 7 is inserted into the arc-shaped clamping groove 9 to complete the limiting and fixing of the reflector bracket 3. The sliding rod 6 is responsible for assisting the sliding of the locking rib 7 and connecting the locking rib 7 and the shock-absorbing springs 8.

[0033] The top of the tooling base 1 is equipped with a UV ultraviolet light downward irradiation reflector 4 to accelerate the curing of UV adhesive.

[0034] Working principle:

[0035] A mounting groove 2, matching the shape of the reflector bracket 3, is formed in the middle of the tooling base 1. The reflector bracket 3 is inserted into the mounting groove 2 by plugging in, forming an initial mechanical positioning. This shape matching ensures accurate installation orientation and limits its horizontal displacement.

[0036] A pre-drilled gap 5 is provided between the top of the reflector bracket 3 and the reflector 4 for injecting UV adhesive. After the adhesive is filled, the curing reaction needs to be triggered by UV irradiation.

[0037] A UV light source is installed on the top of the tooling base 1, and the light shines downwards onto the reflector 4. The ultraviolet light penetrates the reflector 4 and causes the photoinitiator in the adhesive to decompose, generating free radicals and triggering a polymerization reaction, which causes the adhesive to quickly change from a liquid state to a solid state, thereby achieving the bonding and fixation of the reflector 4 and the reflector bracket 3.

[0038] The damping spring 8 is installed inside the tooling base 1, constantly applying an inward elastic thrust to the sliding rod 6, pushing the locking ridge 7 towards the reflector bracket 3. The front end of the locking ridge 7 is inserted into the arc-shaped clamping groove 9 on the outer wall of the reflector bracket 3, utilizing the curved surface characteristics of the arc-shaped clamping groove 9 to form a radial limit. The spring thrust maintains continuous clamping, avoiding stress concentration caused by rigid connection.

[0039] The elastic locking mechanism achieves gapless clamping of the reflector bracket through a combination of spring thrust and curved surface engagement. This not only counteracts the buffering effect of the external vibration damping spring 8, but also prevents the reflector bracket 3 from loosening during optical adjustment.

[0040] The reflector 4 is equipped with a light-transmitting coating to enhance the intensity of the irradiated ultraviolet light. It is suitable for the ultraviolet region of 250nm-400nm, increases the transmittance of ultraviolet light, enables deep penetration and curing, and gives the UV adhesive layer adhesion, creating bonding toughness, which can optimize the curing effect and product quality.
