Description

Technical Field

[0001] This invention belongs to the field of industrial cameras, and particularly relates to an optical lens side-mount module, tooling and equipment. Background Technology

[0002] In traditional optical systems, multiple optical lenses are often side-mounted within the same lens barrel. The relative positions of the lenses are essentially fixed and cannot be adjusted. Once the optical lenses are assembled within the lens barrel, the lens quality is determined, which necessitates high precision in the installation of both the lens barrel and the optical lenses.

[0003] Currently, when optical lenses are installed using a side-insertion method, they are fixed by applying adhesive. However, simple adhesive fixing, whether during the pressing process or after the adhesive has solidified, may cause the optical lens to deflect to a certain extent, thus failing to be fixed in the intended position. This greatly affects the quality of the optical lens and the accuracy of measurement, and consequently affects the quality of the entire camera module and its application products.

[0004] To address this issue, an optical lens side-insertion module, tooling, and equipment are provided, which can ensure that the optical lens is stably installed according to a predetermined position. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems in the prior art and to provide an optical lens side-insertion module, tooling and equipment.

[0006] To achieve the above-mentioned technical objectives and effects, the present invention is implemented through the following technical solution: An optical lens side-mount module, comprising: The housing includes a side insertion cavity for accommodating an optical lens, and a limiting cavity is provided at the opening of the side insertion cavity; The first side insert includes a connecting section and a limiting section. The connecting section includes a pressing part and a guiding part that are distributed opposite to each other. The pressing part is in close contact with the optical lens. The limiting section is in contact with the outer end face of the limiting cavity to restrict the movement of the first side insert towards the side insertion cavity. The second side insert includes a fastening section and a positioning section. The fastening section includes a sliding part and a pressing part that are distributed opposite to each other. The sliding part slides in contact with the guide part, and the pressing part is in close contact with the inner wall of the limiting cavity to restrict the movement of the sliding part. The positioning section is fixedly connected to the housing.

[0007] Furthermore, the inner wall of the limiting cavity includes a clamping plane that adapts to the clamping part.

[0008] Furthermore, the guide surface is formed by scanning an arbitrary curve segment along a straight path, and the distance between the straight path and the mating plane decreases from the outside to the inside, so that the sliding part adapts to the guide surface.

[0009] Furthermore, an installation groove is provided on the outer side of the limiting cavity, which is used to accommodate the limiting section of the first side plug and the positioning section of the second side plug.

[0010] Furthermore, the clamping part includes a clamping plane that fits tightly against the optical lens.

[0011] Furthermore, a protrusion is provided at the connection between the pressing plane and the limiting section, and the farthest distance between the protrusion and the pressing plane is less than the thickness of the optical lens.

[0012] Furthermore, it also includes a synchronous clamping component, fixed to the outside of the second side plug, comprising two synchronous clamping sections, each including a synchronous clamping plane coplanar with the clamping plane.

[0013] Furthermore, a first quick slot is provided on the outer side of the second side plug, and the synchronous clamping member has a quick insertion part adapted to the first quick slot. The two sides of the quick insertion part are connected to the synchronous clamping section through transition connecting sections.

[0014] The present invention also provides an optical lens side-insertion fixture, applied in the above-mentioned optical lens side-insertion module, comprising: The base includes two supporting parts; The guide component is connected to the support at both ends; Two clamping components are slidably mounted on the guide component; The elastic component is slidably mounted on the guide, with the support and clamping components connected at both ends respectively.

[0015] The present invention also provides an optical lens side-insertion device, including the above-mentioned optical lens side-insertion module.

[0016] The beneficial effects of this invention are: 1. The present invention, through the assembly design of the first side plug and the second side plug, can quickly press and fix the optical lens on both sides after insertion, so that the final optical lens can be stably installed and fixed according to the predetermined posture, avoiding deflection that would affect the measurement accuracy.

[0017] 2. The present invention, through the cooperative design of the guide part and the sliding part, can provide a stable and fast installation trajectory for the installation of the second side plug-in. Through continuous adjustment, the clamping part can be tightly fitted with the optical lens, which is suitable for clamping and fixing optical lenses of various sizes.

[0018] 3. Through the supplementary design of the synchronous clamping component, this invention can ensure that the optical lens is stably clamped while avoiding slight warping that would affect its performance and lifespan.

[0019] 4. Through the auxiliary design of the optical lens side insertion fixture, this invention not only enables the rapid installation of the first and second side inserts, but also avoids interference between the optical lens and the first side insert when the optical lens is offset, thus further ensuring the smooth progress of the entire installation process.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, this embodiment first provides an optical lens side-insertion module, including: The housing 1 includes a side insertion cavity 11 for accommodating the optical lens 2. A limiting cavity 12 is provided at the opening of the side insertion cavity 11. In a preferred embodiment, the limiting cavity 12 is specifically located at the middle position of the opening of the side insertion cavity 11 and above the optical lens 2, which facilitates the subsequent installation of other components after the optical lens 2 is inserted. At the same time, in order to further improve the stability of the optical lens 2, glue grooves 14 can also be provided at the lower positions of both ends of the opening of the side insertion cavity 11, and glue for bonding the optical lens 2 can be arranged in the glue grooves 14.

[0024] The first side insert 3 includes a connecting section 31 and a limiting section 32. The connecting section 31 includes a pressing part 311 and a guiding part 312 that are distributed opposite to each other. The pressing part 311 is in close contact with the optical lens 2. The limiting section 32 is in contact with the outer end face of the limiting cavity 11 to restrict the first side insert 3 from moving towards the side insert cavity 11. The second side plug 4 includes a fastening section 41 and a positioning section 42. The fastening section 41 includes a sliding part 411 and a pressing part 412 that are distributed opposite to each other. The sliding part 411 slides in contact with the guide part 312, and the pressing part 412 is in close contact with the inner wall of the limiting cavity 12 to restrict the movement of the sliding part 411. The positioning section 42 is fixedly connected to the housing 1.

[0025] During operation, the optical lens 2 is first inserted into the side insertion cavity 11 for initial installation. Then, the first side plug 3 is installed by pushing the connecting section 31 into the limiting cavity 12 until the limiting section 32 contacts the outer end face of the limiting cavity 12 and can no longer be pushed in. At this point, the pressing part 311 overlaps with the optical lens 2. Next, the second side plug 4 is installed, so that the sliding part 411 slides inward along the guide part 312. Finally, the pressing part 412 will be in close contact with the inner wall of the limiting cavity 12. The fastening section 41 and the connecting section 31 will be firmly restricted in the limiting cavity 12. Under the action of force, an effective compression is formed on the optical lens 2, thereby ensuring that the optical lens 2 is stably installed in the side insertion cavity 11.

[0026] As a preferred embodiment of the limiting cavity 12, the inner wall of the limiting cavity 12 includes a clamping plane 121 adapted to the clamping part 412. In order to facilitate processing and improve the fit stability between the clamping plane 121 and the clamping part 412, the clamping plane 121 can be set as a smooth plane parallel to the optical lens 2, thereby reducing the uneven pressure on the surface of the optical lens 2 caused by the unevenness of the surface between the clamping part 412 and the clamping plane 121.

[0027] In a preferred embodiment of the guide portion 312, the surface of the guide portion 312 is formed by scanning an arbitrary curve segment along a straight path. The distance between the straight path and the mating plane decreases from the outside to the inside, and the sliding portion adapts to the surface of the guide portion. The curve segment can be understood as any continuous trajectory including straight lines, broken lines, arcs, etc. As a special form of expression, a straight line will form a plane after scanning along the straight path. In a preferred embodiment of the guide portion 312, a straight line parallel to the optical lens 2 can be selected to form a smooth inclined surface after scanning along the straight path, so that the sliding portion 411 can slide smoothly along the inclined surface. Combined with the setting of the mating plane 121 in the above embodiment, the mating portion 412 is finally tightly attached to the mating plane 121, so as to achieve uniform pressure on the surface of the optical lens 2.

[0028] To avoid the limiting section 32 and positioning section 42 affecting the overall installation space of the device after the first side plug-in 3 and the second side plug-in 4 are installed, the housing 1 can be designed for compatibility, such as... Figure 1 As shown, a mounting groove 13 is provided on the outer side of the limiting cavity 12. The mounting groove 13 is used to accommodate the limiting section 32 of the first side plug 3 and the positioning section 42 of the second side plug 4. Furthermore, a positioning screw hole can be provided on the inner surface of the mounting groove 13 so that the bolt can pass through the positioning section 42 and be fixedly connected to the positioning screw hole.

[0029] In a preferred embodiment of the pressing part 311, the pressing part 311 includes a pressing plane that fits tightly against the optical lens. The flat design of the pressing plane ensures uniform pressure on the surface of the optical lens 2. In a preferred embodiment, the surface of the pressing plane is also provided with at least one groove. The groove extends to the outer surface of the connecting section 31. When the pressing plane presses against the surface of the optical lens 2, the groove can be connected to the outside, avoiding negative pressure when two smooth planes come into contact. This facilitates disassembly and saves material costs while meeting the pressing requirements.

[0030] During actual assembly, there is often a certain amount of clearance between the two ends of the optical lens 2 and the two ends of the side insertion cavity 11. Therefore, in order to ensure that the optical lens 2 is aligned with the center of the side insertion cavity 11 as much as possible after central assembly, a protrusion 313 can be provided at the connection between the pressing plane and the limiting section 32. During installation, the protrusion 313 pushes the optical lens 2 toward the center of the side insertion cavity 11. After the first side inserts 3 on both sides of the optical lens 2 are installed together, the protrusion 313 will supplement the above-mentioned clearance to a certain extent. When selecting the specific size of the protrusion 313, considering the processing accuracy and tolerance, a certain gap can be left between the protrusion 313 and the optical lens 2 after installation. On the other hand, the farthest distance between the protrusion 313 and the pressing plane is less than the thickness of the optical lens, thereby avoiding interference when the pressing plane squeezes the optical lens 2 and ensuring the smooth progress of subsequent operations.

[0031] Since the first side insert 3 only presses against the opposite two sides of the optical lens 2, this pressing may cause slight warping of the surface of the optical lens 2, thus affecting the use and lifespan of the optical lens 2. To address this, a synchronous pressing component 5 can be included, fixed to the outside of the second side insert 4, such as... Figure 4 and Figure 5 As shown, there are two synchronous pressing sections 53 distributed on both sides. The synchronous pressing section includes a synchronous pressing plane 54 that is coplanar with the pressing plane. After the two synchronous pressing sections 53 are inserted, they will contact the other two sides of the optical lens 2. Therefore, as the second side plug 4 is installed, when the first side plug 3 moves, it will simultaneously drive the synchronous pressing part 5 to move, thereby achieving simultaneous pressing of the four sides of the optical lens 2, which to a certain extent avoids the occurrence of slight warping.

[0032] Considering the limited space of the side insertion cavity 11, for the use of the synchronous clamping member 5, synchronous clamping slots 15 adapted to the synchronous clamping section 53 can be opened at the upper positions of both ends of the side insertion cavity 11. The synchronous clamping slots 15 are connected to the side insertion cavity 11, thereby ensuring the smooth insertion of the synchronous clamping section 53 and achieving the clamping of the optical lens 2.

[0033] As a preferred embodiment of the synchronous clamping element 5, such as Figure 3 As shown, a first slot 314 can be provided on the outside of the second side plug-in 4, such as... Figure 5 As shown, the synchronous clamping member 5 has a quick-insertion portion 51 adapted to the first quick slot 314, and the two sides of the quick-insertion portion 51 are connected to the synchronous clamping section 53 through transition connecting sections 52.

[0034] The first quick-connect slot 314 can adopt any groove structure that facilitates quick insertion and achieves a stable and tight fit with the quick-connect part 51. It can adopt an inwardly concave structure that is larger on the outside and smaller on the inside, or it can adopt a specific structure that is easy to manufacture, such as... Figure 6As shown, the inner surface of the first quick slot 314 may include an inner inclined surface 315, an inner bottom surface 316, and an inner top surface 317 connected in sequence, forming an opening structure that is larger on the outside and smaller on the inside. At the same time, the quick insertion part 51 is adapted to it, including a quick insertion inclined surface 511 and a quick insertion top surface 512, so as to achieve a tight contact connection between the quick insertion inclined surface 511 and the inner inclined surface 315, and between the quick insertion top surface 512 and the inner top surface 317, thereby ensuring that the synchronous clamping member 5 can be stably fixed on the outside of the first side plug 3.

[0035] The base 6 can be fixed on any support frame or operated by hand. As mentioned above, after the two first-side plug-ins 3 are installed on both sides of the optical lens 2, the first-side plug-ins 3 need to be pressed inward to make the limiting section 32 and the outer end face of the limiting cavity 12 in close contact. In actual operation, the installation of the first-side plug-ins 3 and the second-side plug-ins 4 on one side can usually be completed first, and then the installation operation on the other side can be carried out. However, if the optical lens 2 is biased to one side during the initial installation, and the second-side plug-ins 4 on the other side are fixed, the protrusion 313 of the first-side plug-ins 3 on that side will form a relatively large gap with the optical lens 2. As a result, when the first-side plug-ins 3 on the other side are installed, the protrusion 313 will have difficulty pushing the fixed optical lens 2 to center, resulting in interference and causing some inconvenience to the actual installation.

[0036] Therefore, to avoid this situation, the second aspect of the present invention also provides an optical lens side-insertion fixture, applied in the aforementioned optical lens side-insertion module, to facilitate the rapid and stable installation of the aforementioned optical lens side-insertion module, such as... Figure 7 and Figure 8 As shown, specifically including The base 6 includes two support parts 61; Guide component 7 is connected to support component 61 at both ends; Two clamping parts 8 are slidably mounted on the guide part 7; The elastic component 9 is slidably mounted on the guide component 7, and its two ends are respectively connected to the support component 61 and the clamping component 8.

[0037] In a specific implementation, the two clamping members 8 can simultaneously clamp the synchronous clamping members 5 on both sides of the optical lens side insertion module, or they can directly clamp the two first side plugs 3 simultaneously without using the synchronous clamping members 5, so that the protrusions 313 of the two first side plugs 3 are pushed inward at the same time, realizing the effective centering of the optical lens 2, thereby ensuring the smooth progress of the installation operation; at the same time, due to the pre-clamping effect of the two clamping members 8 on the two first side plugs 3, it is also convenient for the subsequent rapid and stable installation of the second side plug 4.

[0038] As a preferred embodiment of the optical lens side-insertion fixture, its specific structure is as follows: Support parts 61 are symmetrically distributed at both ends of the base 6. Positioning holes 62 are provided through the surface of the support parts 61. The guide 7 can be a rod-shaped structure, with both ends inserted into the positioning holes 62 and interference fit therewith. The elastic component 9 can be a spring structure and is slidably installed on the guide 7. One end of the elastic component 9 abuts against the support part 61, and the other end contacts the clamping component 8. In the free state of the elastic component 9, the distance between the two clamping components 8 is less than the predetermined installation distance of the two first side plug-in 3. When in use, the clamping components 8 can be quickly clamped by moving them to both sides.

[0039] As a preferred embodiment of the clamping member 8, it may specifically include a sliding connecting plate 81, with a clamping side plate 83 connected to the periphery of the sliding connecting plate 81 via an intermediate connecting plate 82, and a sliding connecting hole 84 in the middle of the sliding connecting plate 81 that cooperates with the guide member 7.

[0040] As a specific implementation of the intermediate connecting plate 82 and the clamping side plate 83, any structural shape can be used as long as it does not affect the subsequent installation of the second side plug-in 4 after clamping.

[0041] To prevent the relative rotation between the base 6, guide 7, and clamping member 8 from affecting the clamping effect, a first limiting protrusion 63 can be provided in the positioning hole 62, a limiting groove 71 that cooperates with the first limiting protrusion 63 is provided on the periphery of the guide 7, and a second limiting protrusion 85 that cooperates with the limiting groove 71 is provided in the sliding connection hole 84.

[0042] When the above-mentioned tooling is used, it can be used for clamping the synchronous clamping member 5, or for directly clamping the first side plug 3 when the synchronous clamping member 5 is not present. Therefore, it can specifically include the following implementation methods: As a first embodiment of the optical lens side insertion fixture, when the optical lens side insertion module does not have a synchronous clamping member 5, the surface of the clamping side plate 83 is provided with an insertion protrusion 86 that cooperates with the first fast slot 314. The specific details of the insertion protrusion 86 can be adaptively adjusted according to the actual structure of the first fast slot 314.

[0043] As a second embodiment of the optical lens side insertion fixture, when the optical lens side insertion module has a synchronous clamping member 5, an outer plate 55 can be provided on the outside of the quick insertion part 51, and a second quick slot 56 can be provided on the surface of the outer plate 55. The specific structure of the second quick slot 56 can be set with reference to the first quick slot 314, and the insertion protrusion 86 provided on the surface of the clamping side plate 83 is adapted to the second quick slot 56.

[0044] As a third embodiment of the optical lens side insertion fixture, unlike the second embodiment described above, the second quick slot 56 can have the same groove structure as the first quick slot 314, so that regardless of whether the synchronous clamping member 5 is used, a uniform corresponding insertion protrusion 86 can be used for quick insertion and clamping.

[0045] A third aspect of the present invention also provides an optical lens side-insertion device, including the above-described optical lens side-insertion module.
