Detailed implementation manners

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with 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. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present disclosure, unless otherwise stated, the meaning of "a plurality" is two or more.

[0048] In addition, the use of "based on" or "in accordance with" means open and inclusive, because a process, step, calculation, or other action "based on" or "in accordance with" one or more conditions or values may, in practice, be based on additional conditions or values beyond those stated.

[0049] As a core component of an optical system, the assembly accuracy and glue layer uniformity of a curved prism assembly have a decisive impact on the overall performance and stability of the optical system. Among them, the glue injection process of the prism refers to the process method of combining multiple prisms through a gluing technique. The key to this process lies in selecting the appropriate glue and precisely controlling the gluing process to ensure that the prism assembly has high light transmittance and resistance to light and heat.

[0050] Applying a thin layer of glue on the side of the prism during the glue injection process of the prism can make the surface of the prism smoother, thereby reducing the losses of reflection and refraction and ensuring the purity and clarity of light. Traditional prism glue injection assembly methods have problems such as insufficient assembly accuracy and uneven distribution of the glue layer thickness, which seriously restrict the improvement of the performance of the optical system.

[0051] To solve the above problems, the present application provides a high-precision assembly glue injection device for a curved prism, as Figure 1 shown. The device includes:

[0052] A frame 2, and the curved prism 1 is fixed in the frame 2;

[0053] A plurality of mounting holes are provided on the frame 2, the mounting holes are used to connect an adhesive ring, and a ring trimming pad 5 is further provided between the adhesive surface of the adhesive ring and the side surface of the curved prism 1, and the ring trimming pad 5 is used to control the gap size between the adhesive ring and the side surface of the curved prism 1;

[0054] A plurality of first glue injection holes 6 are also formed on the frame 2, and the glue injection tool 10 performs first glue injection on the side surface of the curved prism 1 through the first glue injection holes 6;

[0055] The bonding ring includes a second glue injection hole 7, and the glue injection tool 10 performs second glue injection on the side surface of the curved prism 1 in batches through the second glue injection hole 7.

[0056] Among them, the frame 2 for prism glue injection is usually a fixture or bracket for fixing the prism, ensuring that the prism maintains the correct position and angle during glue injection. The design of the frame 2 needs to consider the shape and size of the prism to provide stable support during the glue injection process and prevent glue from overflowing or contaminating the optical surface. The material of the frame 2 should have good mechanical strength and chemical resistance to withstand the pressure and possible chemical corrosion during the glue injection process.

[0057] In the prism glue injection process, the bonding ring can be an annular structure for fixing and positioning the prism, usually made of metal or plastic. Its main function is to ensure that the prism maintains an accurate position and angle during the glue injection process, while preventing glue from overflowing or contaminating the optical surface.

[0058] The ring trimming pad 5 is usually made of a soft and chemical-resistant material, such as silica gel, rubber or Teflon (PTFE), to avoid reacting with the glue or damaging the prism surface. The ring trimming pad 5 can be annular, sheet-shaped or other customized shapes according to the design of the prism and the frame 2 to adapt to specific glue injection requirements. The ring trimming pad 5 is used to trim or adjust the shape and thickness of the glue layer after glue injection to ensure the uniformity and accuracy of the glue layer. The ring trimming pad 5 is used in cooperation with the bonding ring to help control the distribution and curing effect of the glue.

[0059] Optionally, the first glue injection uses silicone rubber, and the second glue injection uses epoxy glue; the gap between the bonding ring and the side surface of the prism is 0.08 mm - 0.17 mm.

[0060] Optionally, a plurality of tooling pressing pieces 11 are connected to the bottom of the frame 2, and the flat surface of the curved prism 1 is placed on the tooling pressing pieces 11 in the frame 2;

[0061] As Figure 2 shown, an equal-thickness tooling 8 is also arranged in the gap between the frame 2 and the side surface of the curved prism 1, and the equal-thickness tooling 8 is used to control the position of the curved prism 1 in the frame 2 so that the center of the curved prism 1 is within the target position range in the frame 2.

[0062] Among them, the tooling pressing piece 11 can be used to fix and press the prism. It can keep the stable position of the prism during the glue injection process, prevent it from moving or tilting, so as to ensure the accuracy and consistency of the glue injection. The tooling pressing piece 11 can be designed into a sheet shape, a ring shape or other customized shapes according to the shape and size of the prism. Its surface is usually smooth to avoid scratching the optical surface of the prism.

[0063] According to the size of the gap between the measuring frame 2 and the side surface of the curved prism 1, and adjusting the thickness of the equal-thickness tooling 8, it can ensure that the gap between the curved prism 1 and the frame 2 is uniform, so that the curved prism 1 is placed in the center of the frame 2, that is, the center of the curved prism 1 is located within the target position range in the frame 2.

[0064] Optionally, as Figure 3 shown, the bonding ring includes a flexible bonding ring 4 and a rigid bonding ring 3; one flexible bonding ring 4 and one rigid bonding ring 3 are respectively connected to two opposite side surfaces of the frame 2. By respectively connecting one flexible bonding ring 4 and one rigid bonding ring 3 to two opposite side surfaces of the frame 2, the stress of the curved prism 1 can be ensured to meet the requirements.

[0065] Optionally, as Figure 4 and Figure 5 shown, the device further includes a support tooling 9, and the end surface of the frame 2 is connected to the support tooling 9;

[0066] The support tooling 9 is used to mount the curved prism 1 in the frame 2 on the detection optical path, so that the detection optical path performs surface shape detection on the curved prism 1. Among them, the surface shape detection is mainly used to detect the stress change amount of the curved prism 1.

[0067] Based on the high-precision assembly and glue injection device for the curved prism provided by the embodiments of the present application, the present application also provides a high-precision assembly and glue injection method for the curved prism, as Figure 6 shown, the method includes the following steps:

[0068] Step 601, fix the curved prism 1 in the frame 2.

[0069] Among them, a plurality of tooling pressing pieces 11 are connected to the bottom of the frame 2, and an equal-thickness tooling 8 is also arranged in the gap between the frame 2 and the side surface of the curved prism 1.

[0070] Optionally, the process of fixing the curved prism 1 in the frame 2 can be: placing the curved prism 1 flat on the tooling pressing piece 11 in the frame 2, and inserting an equal-thickness tooling 8 into the side gap between the frame 2 and the curved prism 1, so that the center of the curved prism 1 is located within the target position range in the frame 2. Among them, the target position range can be the central position area of the frame 2.

[0071] In the actual process, before fixing the curved surface prism 1 to the spectacle frame 2, it is necessary to precisely clean the spectacle frame 2 to ensure that there are no impurities such as dust and oil stains. And check and remove the burrs on the spectacle frame 2 to ensure the smoothness and flatness of the assembly surface in the spectacle frame 2. Then use the tooling pressing piece 11 to place the optical element of the curved surface prism 1 stably in the spectacle frame 2 to ensure that the surface of the optical element is not damaged. Protect the curved surface prism 1 with capacitor paper to avoid scratches during the assembly process, and then insert the equal-thickness tooling 8 into the side gap between the spectacle frame 2 and the curved surface prism 1. Through precise measurement and adjustment, ensure that the gap between the optical element and the spectacle frame 2 is uniform, and ensure that the curved surface prism 1 is placed in the center of the spectacle frame 2.

[0072] Step 602: Connect an adhesive ring to the mounting hole on the spectacle frame 2, and detect the first distance between the adhesive surface of the adhesive ring and the side surface of the curved surface prism 1.

[0073] Among them, a plurality of mounting holes are provided on the spectacle frame 2, and the mounting holes are used to connect the adhesive ring. The adhesive ring includes an adhesive surface.

[0074] Step 603: Select a ring trimming pad 5 with a target thickness according to the first distance.

[0075] Step 604: After setting the ring trimming pad 5 between the adhesive surface of the adhesive ring and the side surface of the curved surface prism 1, install the adhesive ring on the spectacle frame 2 so that the gap between the adhesive ring and the side surface of the curved surface prism 1 is controlled within a preset gap.

[0076] In the actual process, use a precision plug gauge to measure the gap between the adhesive surface of the adhesive ring and the side surface of the curved surface prism 1 after the adhesive ring is screwed to the spectacle frame 2 to ensure the accuracy of the measurement result. Then grind the ring trimming pad 5 of the adhesive ring, and control the gap between the adhesive ring and the prism through precision machining, that is, control the thickness of the adhesive layer. After ensuring that the gap between the adhesive ring and the side surface of the curved surface prism 1 is controlled within 0.08 mm - 0.17 mm, install the bonding ring and the ring trimming pad 5 on the spectacle frame 2 with screws, and ensure the consistency of the tightening torque of the spectacle frame 2.

[0077] Optionally, after installing the adhesive ring on the spectacle frame 2 in the above step 604, the method further includes:

[0078] Connect the end face of the spectacle frame 2 to the support tooling 9, and use the support tooling 9 to mount the curved surface prism 1 in the spectacle frame 2 on the detection optical path;

[0079] Perform the first surface shape detection on the surface prism 1. If the stress change amount of the surface prism 1 detected by the first surface shape detection is less than the first threshold, use the injection tool 10 to perform the first injection on the side surface of the surface prism 1 from multiple first injection holes 6 on the frame 2. Among them, the stress change amount can be the difference between the initial stress of the surface prism and the stress detected by the surface shape detection, and the initial stress can be set to zero.

[0080] In the actual process, connect the frame 2 with the surface prism 1 fixed thereon to the support tooling 9. When connecting, the frame 2 can be connected to the support tooling 9 through the flange on the end face of the frame 2. Then set up the precision detection optical path and perform the first surface shape detection on the surface prism 1 assembly. If the stress change amount of the surface prism 1 detected by the first surface shape detection is less than the first threshold, where the first threshold can be 0.003λ and λ is the wavelength of the detection light in the detection optical path. Then place the frame 2 with the surface prism 1 fixed thereon on the optical platform, place the surface prism 1 on the detection optical path, and after making the focus of the surface prism 1 coincide with the focus of the surface shape detection device, start the injection operation.

[0081] Step 605: After performing the first injection on the side surface of the surface prism 1 from multiple first injection holes 6 on the frame 2 using the injection tool 10 and curing, use the injection tool 10 to perform the second injection on the side surface of the surface prism 1 in batches from the second injection hole 7 on the frame 2 and cure.

[0082] Optionally, in the actual injection process, use the injection tool 10 to perform the first injection from multiple first injection holes 6 on the frame 2 in a multi-point simultaneous injection manner to perform a preliminary positioning on the surface prism 1 to ensure the uniformity of the glue layer distribution. After curing the glue injected for the first time for several hours, perform the surface shape detection again. Among them, the first injection can use silicone rubber.

[0083] Optionally, the process of using the injection tool 10 to perform the second injection on the side surface of the surface prism 1 in batches from the second injection hole 7 on the frame 2 and curing in step 605 can be:

[0084] Use the injection tool 10 to first inject epoxy glue from the second injection hole 7 in the rigid bonding ring 3 and cure, and then perform the second surface shape detection on the surface prism 1 in the frame 2;

[0085] If the stress change amount of the surface prism 1 detected by the second surface shape detection is less than the second threshold, use the injection tool 10 to inject epoxy glue from the second injection hole 7 in the flexible bonding ring 4 and cure again.

[0086] Among them, the second threshold can also be 0.003λ.

[0087] Optionally, after injecting epoxy glue through the second glue injection hole 7 in the flexible bonding ring 4 using the glue injection tool 10 and curing it, the method further includes:

[0088] Removing the equal-thickness tooling 8 in the frame 2 and performing a third surface shape detection on the curved prism 1 in the frame 2.

[0089] Among them, for the third surface shape detection, it is required to detect that the stress change amount of the curved prism 1 is less than a third threshold value, and this third threshold value can be 0.010λ.

A ring trimming pad 5 is further provided between the bonding surface of the bonding ring and the side surface of the curved prism 1.

During the glue injection process, the curved prism 1 is fixed in the frame 2, the bonding ring is connected to the mounting holes on the frame 2, and the first distance between the bonding surface of the bonding ring and the side surface of the curved prism 1 is detected. According to the first distance, a ring trimming pad 5 with a target thickness is selected; after the ring trimming pad 5 is arranged between the bonding surface of the bonding ring and the side surface of the curved prism 1, the bonding ring is installed on the frame 2 to control the gap between the bonding ring and the side surface of the curved prism 1 within a preset gap; after using the glue injection tool 10 to perform the first glue injection on the side surface of the curved prism 1 through the plurality of first glue injection holes 6 on the frame 2 and curing it, the glue injection tool 10 is used to perform the second glue injection on the side surface of the curved prism 1 in batches through the second glue injection hole 7 on the frame 2 and curing it.
