Description

Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to a lens disassembly jig assembly. Background Art

[0002] The lens is usually fixed inside the lens barrel by dispensing glue or hot melting. During the production process, if the lens is not assembled properly or the resolution yield is unsatisfactory, the lens needs to be disassembled from the lens barrel and recycled.

[0003] There are two ways to remove the lens from the lens barrel: knife cutting and ejection. The ejection method uses a pressure head to eject the lens from the inside of the lens barrel. The ejection method can only be used for lenses fixed by glue. Hot-melt lenses have strong fixing ability and cannot be ejected by ejection. There are two types of knife cutting. The first knife cutting method is to fix the lens on the fixture and use a tool to cut the lens barrel in half radially to remove the lens. However, the edge thickness of the lens is relatively thin, and this knife cutting method can easily cause the lens to break. The second knife cutting method is to fix the lens on the fixture and use a tool to cut the lens barrel in a circumferential manner. This knife cutting method can prevent the lens from breaking, but there is currently no suitable fixture to install and fix the tool, and the tool is inconvenient to disassemble and adjust. Utility Model Content

[0010] The first screw passes through the connecting hole of the cutter head and is threadedly connected to the first threaded hole of the disassembly seat. The first screw locks the cutter head to the disassembly seat.

[0011] As an optional technical solution, a side of the disassembly seat facing the mounting seat is provided with an avoidance groove, the first threaded hole is opened at the bottom of the avoidance groove, the depth of the avoidance groove along the axial direction of the accommodating hole is greater than the height of the cutter head along the axial direction of the accommodating hole, and the cutter head is completely accommodated in the avoidance groove.

[0012] As an optional technical solution, two of the cutter heads and two of the first screws are provided, the disassembly seat is provided with two first threaded holes, and the two first threaded holes, the two cutter heads and the two first screws are arranged in a one-to-one correspondence.

[0019] As an optional technical solution, the handle seat is a cylindrical structure, and the outer periphery of the handle seat is provided with a reticulated knurling.

[0020] Beneficial effects of the utility model:

[0021] The lens disassembly jig assembly provided by the utility model includes a mounting seat, a disassembly seat, a cutter head and a first screw; the disassembly seat is provided with a accommodating hole, one end of the lens is fixedly mounted on the mounting seat, and the other end of the lens faces the accommodating hole, and the side wall of the accommodating hole is provided with a first threaded hole, and the central axis of the first threaded hole is parallel to the central axis of the accommodating hole; the cutter head is provided with a connecting hole, and the cutter head is located on the side of the disassembly seat facing the mounting seat; the first screw passes through the connecting hole of the cutter head and is threadedly connected to the first threaded hole of the disassembly seat, and the first screw locks the cutter head to the disassembly seat.

[0022] The lens includes a lens barrel and a lens installed inside the lens barrel. When the lens needs to be taken out from the inside of the lens barrel, one end of the lens is fixedly installed on the mounting seat, and the other end of the lens is directed toward the accommodating hole of the disassembly seat. The central axis of the lens coincides with the central axis of the accommodating hole. Then the mounting seat and the disassembly seat are rotated relative to each other and approach each other. For example, the mounting seat is fixed and the disassembly seat rotates around the central axis of the accommodating hole, or the mounting seat rotates around the central axis of the accommodating hole and the disassembly seat is fixed. Alternatively, both the mounting seat and the disassembly seat rotate around the central axis of the accommodating hole, but the rotation direction of the mounting seat is opposite to that of the disassembly seat. When the mounting seat and the disassembly seat rotate relative to each other and approach each other, the blade of the cutter head cuts the lens barrel, and the lens can be obtained after the lens barrel is cut off.

[0023] In the present invention, the distance between the blade of the cutter head and the central axis of the receiving hole can be adjusted. For example, by loosening the first screw and rotating the cutter head, since the blade is biased to one side of the connecting hole, the blade can be close to or away from the central axis of the receiving hole. Therefore, it is possible to cut lens barrels of different outer diameters, and has a wide range of applications. Even for lens barrels of the same diameter, the cutting thickness of the lens barrel by the cutter head can be adjusted. For example, when the distance between the blade and the central axis of the receiving hole is equal to the radius of the lens, the blade only needs to move one stroke to cut the lens barrel. At this time, the cutting thickness of the blade is equal to the lens diameter. Due to the wall thickness of the lens barrel, the force on the blade is relatively large. You can also first make the distance between the blade and the central axis of the accommodating hole greater than the radius of the lens and smaller than the radius of the lens barrel. The blade moves one stroke first. At this time, the cutting thickness of the blade is less than the wall thickness of the lens barrel, and the force on the blade is smaller. Then adjust the position of the blade so that the distance between the blade and the central axis of the accommodating hole is equal to the radius of the lens. The blade moves one stroke again to cut off the remaining material of the lens barrel. Switching the lens barrel twice, the thickness cut by the blade is thinner each time, which can reduce the force on the blade and prevent the blade from loosening.

[0024] In the utility model, the first screw is used to lock the cutter head to the disassembly seat, which facilitates the replacement of cutter heads of different specifications.

[0025] In the utility model, when the lens barrel is cut, the disassembling seat and the mounting seat are brought closer to each other, and the lens can gradually extend into the accommodating hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0039] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0040] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] like Figures 1 to 5 As shown, the lens disassembly jig assembly provided in this embodiment includes a mounting base 1, a disassembly base 2, a cutter head 3 and a first screw 4; the disassembly base 2 is provided with a accommodating hole 21, one end of the lens 100 is fixedly mounted on the mounting base 1, and the other end of the lens 100 faces the accommodating hole 21, and the side wall of the accommodating hole 21 is provided with a first threaded hole, and the center axis of the first threaded hole is parallel to the center axis of the accommodating hole 21; the cutter head 3 is provided with a connecting hole 31, and the cutter head 3 is located on the side of the disassembly base 2 facing the mounting base 1; the first screw 4 passes through the connecting hole 31 of the cutter head 3 and is threadedly connected to the first threaded hole of the disassembly base 2, and the first screw 4 locks the cutter head 3 to the disassembly base 2.

[0043] When the lens 100 needs to be removed from the inside of the lens barrel, one end of the lens 100 is fixed to the mounting seat 1, and the other end of the lens 100 is directed toward the receiving hole 21 of the disassembly seat 2, and the central axis of the lens 100 coincides with the central axis of the receiving hole 21. Then, the mounting seat 1 and the disassembly seat 2 are rotated relative to each other and approach each other. For example, the mounting seat 1 is fixed, and the disassembly seat 2 rotates around the central axis of the receiving hole 21, and the two are axially approached to each other, or the mounting seat 1 rotates around the central axis of the receiving hole 21, and the disassembly seat 2 is fixed, and the two are axially approached to each other, or both the mounting seat 1 and the disassembly seat 2 rotate around the central axis of the receiving hole 21, but the rotation direction of the mounting seat 1 is opposite to the rotation direction of the disassembly seat 2, and the two are axially approached to each other. When the mounting seat 1 and the disassembly seat 2 rotate relative to each other and approach each other, the blade 32 of the cutter head 3 cuts the lens barrel of the lens 100, and the lens can be obtained after the lens barrel is cut off.

[0044] In this embodiment, the distance between the blade 32 of the cutter head 3 and the central axis of the receiving hole 21 can be adjusted. For example, the first screw 4 is loosened and the cutter head 3 is rotated. Since the blade 32 is biased to one side of the connecting hole 31, the blade 32 can be close to or away from the central axis of the receiving hole 21. Therefore, it can cut lens barrels of different outer diameters and has a wide range of applications. Even for lens barrels of the same diameter, the cutting thickness of the lens barrel by the cutter head 3 can be adjusted. For example, when the distance between the blade 32 and the central axis of the receiving hole 21 is equal to the radius of the lens, the blade 32 only needs to move one stroke to cut the lens barrel. At this time, the cutting thickness of the blade 32 is equal to the lens diameter. The wall thickness of the barrel is large, and the force on the blade 32 is large. You can also make the distance between the blade 32 and the central axis of the accommodating hole 21 greater than the radius of the lens and smaller than the radius of the barrel. The blade 32 moves a stroke first. At this time, the cutting thickness of the blade 32 is less than the wall thickness of the barrel, and the force on the blade 32 is small. Then adjust the position of the blade 32 so that the distance between the blade 32 and the central axis of the accommodating hole 21 is equal to the radius of the lens. The blade 32 moves a stroke again to cut off the remaining material of the barrel. The barrel is switched twice. The thickness cut by the blade 32 each time is thinner, which can reduce the force on the blade 32 and prevent the blade 32 from loosening.

[0045] In this embodiment, the first screw 4 is used to lock the cutter head 3 to the disassembly seat 2, so as to facilitate the replacement of cutter heads 3 of different specifications.

[0046] In this embodiment, when the lens barrel is cut, the disassembly seat 2 and the mounting seat 1 are brought closer to each other, and the lens can gradually extend into the accommodating hole 21 .

[0049] Optionally, a limiting groove 12 is provided on the side of the mounting seat 1 facing the disassembly seat 2 , and a portion of the peripheral wall of the lens 100 is embedded in the limiting groove 12 to prevent the lens 100 from rotating around the central axis of the mounting hole 11 .

[0050] Optionally, a side of the disassembly seat 2 facing the mounting seat 1 is provided with an avoidance groove 22, and a first threaded hole is opened at the bottom of the avoidance groove 22. The depth of the avoidance groove 22 along the axial direction of the accommodating hole 21 is greater than the height of the cutter head 3 along the axial direction of the accommodating hole 21, and the cutter head 3 is completely accommodated in the avoidance groove 22.

[0051] When not cutting, external components hit the cutter head 3 from the end along the axial direction of the accommodating hole 21, thereby protecting the cutter head 3; when the end of the disassembly seat 2 abuts against the mounting part on the periphery of the lens 100 along the axial direction, the disassembly seat 2 and the mounting seat 1 stop approaching each other. At this time, there is still a part of residual material on the periphery of the lens. This part of the residual material fixes the lens to prevent the lens from losing its fixing function and hitting the cutter head 3. At this time, the disassembly seat 2 can be removed and the lens can be sucked away using a suction cup.

[0052] In this embodiment, two cutter heads 3 and two first screws 4 are provided, and the disassembly seat 2 is provided with two first threaded holes. The two first threaded holes, the two cutter heads 3 and the two first screws 4 are arranged in a one-to-one correspondence.
