Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lens assembly, and in particular to a lens assembly device. Background Art
[0002] With the continuous iterative development of the lens market, higher pixel and higher quality lenses have become the common goal pursued in this field, and a canted lens structure has emerged. Different from the traditional lens structure, the lenses in the lens structure are not combined together in a simple stacking manner, which is completely limited by the coaxiality of the inner diameter of the lens barrel; instead, a canted structure is set in the assembly area where the adjacent lenses do not participate in optical imaging. The two adjacent canted lenses are abutted together through the canted structure, so that the lenses are freed from the constraints of the inner diameter of the lens barrel to a certain extent during the assembly process. After assembly, the overall structure is more stable, and the eccentricity error between the lenses after assembly is also greatly reduced. Therefore, whether the lenses are properly fitted during assembly will directly determine the stability of the assembled product;
[0003] However, the current existing method of assembling the combined lens is: Figure 1 The schematic diagram of the existing lens bonding is disclosed. The staff puts the first lens A into a special tray, then applies glue to all the lenses in the tray, then takes the second lens B for assembly and pressing, and finally UV cures the assembled lenses.

[0027] In order to better understand the present invention, various aspects of the present invention will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of embodiments of the present invention, and do not limit the scope of the present invention in any way. It should be noted that in this specification, the expressions of first, second, third, etc. are only used to distinguish one feature from another feature, and do not represent any limitation on the feature.
[0028] It should also be understood that the terms “comprises,” “including,” “having,” “includes” and / or “comprising,” when used in this specification, indicate the presence of stated features, elements and / or components, but do not exclude the presence or addition of one or more other features, elements, components and / or combinations thereof.
[0029] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs. It should also be understood that terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and will not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.
[0030] To understand this design, please refer to Figure 1 As shown, an existing canned lens structure is provided, including a first lens A and a second lens B. After the second lens B is aligned with the first lens A through the canned structure, the two are cured by glue. Among them, since the first lens A and the second lens B are both optical elements and the two need to cooperate for imaging, it is necessary to ensure that the optical axes of the two lenses coincide with each other during installation, that is, the concentricity requirements of the two lenses are very high, that is, to ensure that the optical centers of the two lenses are aligned, commonly known as the two lenses need to be centered. Therefore, when assembling lenses that need to be canned, it is very important to ensure the concentricity of the first lens A and the second lens B. Since the existing technology is to manually cannulate, there are too many uncertain factors when manually assembling lenses.
[0031] In order to facilitate the understanding of this application, Figure 2-Figure 5 As shown, throughout the text, the first direction can be defined as the X direction, and the second direction can be defined as the Y direction. The X direction and the Y direction in each figure show the spatial relationship of the components in the lens clamping device. For example, the X direction is the moving direction of the linear moving platform 10, and the Y direction is the direction perpendicular to the movement of the linear moving platform 10. In addition, the X direction and the Y direction in each figure include not only the direction indicated by the arrow, but also the direction away from the arrow. In other words, the arrows in the X direction and the Y direction do not have a limiting meaning. The same concept will be used throughout the disclosure to describe the spatial relationship of the components in the clamping device.
[0032] The embodiment of the present invention provides a lens assembly device for assembling a first lens A and a second lens B that need to be assembled and fixed. Specifically, Figure 2 and Figure 3As shown, the lens joint device includes: a linear moving platform 10, a positioning bearing mechanism 20 and a squeezing mechanism 30. The positioning bearing mechanism 20 is installed on the linear moving platform 10 and can move along the first direction driven by the linear moving platform 10. The positioning bearing mechanism 20 is used to carry the first lens A and the second lens B. The squeezing mechanism 30 includes a pressure head module 310, which is arranged above the positioning bearing mechanism 20 along the second direction, and the pressure head module 310 is used to squeeze the positioned first lens A and the second lens B by moving downward, wherein the first direction is perpendicular to the second direction. It can be understood that the lens joint device includes three major components, the positioning bearing mechanism 20 for carrying the first lens A and the second lens B, the squeezing mechanism 30 for squeezing and pressing the first lens A and the second lens B, and the linear moving platform 10 that drives the positioning bearing mechanism 20 to move along the first direction. The linear moving platform 10 can be a single cylinder linear module or a pulley drive module. As long as the drive module can drive the positioning bearing mechanism 20 to move, it is not limited here. That is, the first lens A and the second lens B located on the positioning and carrying mechanism 20 can be moved to the bottom of the pressing mechanism 30 through the linear moving platform 10, ensuring that the pressing mechanism 30 can accurately press the first lens A and the second lens B to achieve the combination of the two. Of course, in order to increase the production of lens combination, multiple positioning and carrying mechanisms 20 and multiple pressing mechanisms 30 can be set on the linear moving platform 10 at the same time, such as Figure 2 Two positioning and supporting mechanisms 20 and two pressing mechanisms 30 are provided on the linear moving platform 10 .
[0033] Please refer to Figure 3 As shown, Figure 3An exploded view of the positioning bearing mechanism 20 is provided, in which the platform mechanism 230 installed on the centering mechanism 220 is separated along the second direction. Specifically, the positioning bearing mechanism 20 includes a first base plate 210, a centering mechanism 220 and a platform mechanism 230, wherein the centering mechanism 220 is arranged on the first base plate 210, the platform mechanism 230 is arranged on the centering mechanism 220, and the platform mechanism 230 is used to carry the first lens A and the second lens B, and the centering mechanism 220 adjusts the concentricity of the first lens A and the second lens B by squeezing the first lens A and the second lens B at the same time. Among them, the positioning bearing mechanism 20 is installed on the linear moving platform 10 through the first base plate 210 to ensure the stability of the installation of the positioning bearing mechanism 20. The centering mechanism 220 is configured to squeeze the first lens A and the second lens B placed on the platform mechanism 230 at the same time, thereby ensuring the concentricity of the two. The centering mechanism 220 may be a co-rotating axis structure of two clamping jaws that can realize simultaneous movement toward each other, and the two clamping jaws simultaneously clamp the first lens A and the second lens B to realize centering of the two lenses; or it may be a structure of two sliders that can realize simultaneous movement toward each other, and the two sliders move toward each other to squeeze the first lens A and the second lens B to realize centering of the two lenses. By arranging the positioning bearing mechanism 20 and the squeezing mechanism 30 on the same lens fitting device, and the positioning bearing mechanism 20 is provided with a stage mechanism 230 for carrying the first lens A and the second lens B for centering, and a centering mechanism 220 for squeezing the first lens A and the second lens B to adjust the concentricity of the two, the accuracy of lens fitting is improved, and at the same time, the automation of lens fitting is ensured, thereby reducing the cost of lens fitting.
[0034] Furthermore, the positioning and supporting mechanism 20 also includes a first sliding member 240 and a precision slide 250 arranged on the first base plate 210, the first sliding member 240 includes a first guide rail 241 and a first slide 242, the first slide 242 is slidably arranged on the first guide rail 241 along the first direction, the centering mechanism 220 is installed on the first slide 242 and the precision slide 250, and the precision slide 250 is used to drive the centering mechanism 220 and the first slide 242 to move in the first direction. The first lens A and the second lens B and the stage mechanism 230 are installed on the centering mechanism 220, and the centering mechanism 220 is installed on the first slide 242 and the precision slide 250, and then the first lens A and the second lens B can be adjusted in the first direction through the first slide 242 and the precision slide 250, ensuring that the first lens A and the second lens B can be accurately moved to the right below the squeezing mechanism 30, so as to prevent the pressure head module 310 from squeezing the side of the second lens B, and prevent the first lens A and the second lens B from being misaligned when they are combined, that is, the first slide 242 and the precision slide 250 can improve the accuracy of the combination. It should be noted that the first slide 242 can ensure the stability of the movement of the positioning bearing mechanism 20, and play a role in positioning the movement of the positioning bearing mechanism 20 in the first direction; the precision slide 250 can accurately control its movement amount, thereby ensuring that the first lens A and the second lens B can be accurately moved to the required position.
[0035] Please refer to Figure 4 As shown, the centering mechanism 220 includes a first mounting plate 221, a clamp fixing plate 222, a centering clamp 223 and a centering cylinder 224. The number of the clamp fixing plate 222 and the centering cylinder 224 are both even numbers and are both symmetrically mounted on the first mounting plate 221 along the first direction. The number of the centering clamps 223 is even numbers and are symmetrically mounted on the clamp fixing plate 222 along the first direction. One clamp fixing plate 222 matches one centering clamp 223 and one centering cylinder 224. The centering cylinder 224 is used to drive the centering clamps 223 on the clamp fixing plate 222 to move toward each other. The two centering clamps 223 are used to adjust the concentricity of the first lens A and the second lens B. In order to ensure the concentricity of the first lens A and the second lens B, that is, the optical axes of the two coincide, two centering jaws 223 that move toward each other are arranged on both sides of the first lens A and the second lens B, and two jaw fixing plates 222 that drive the centering jaws 223 to move also need to be arranged and two centering jaws 223 are installed respectively, and two corresponding centering cylinders 224 that drive the jaw fixing plates 222 to move also need to be arranged. It can be understood that in order to increase the production volume of lens fitting, the jaw fixing plates 222, the centering jaws 223 and the centering cylinders 224 can be set to an even number that corresponds to each other. Preferably, the centering mechanism 220 is fixed to the first slide 242 and the precision slide 250 through the first mounting plate 221 to improve the convenience of installing the centering mechanism 220.
[0036] In one embodiment, the centering mechanism 220 further includes a second sliding member 225, the second sliding member 225 includes a second guide rail 2251 and a second slide 2252, the second slide 2252 is slidably disposed on the second guide rail 2251 along the first direction, the second guide rail 2251 is mounted on the first mounting plate 221, and the clamping jaw fixing plate 222 is mounted on the second slide 2252. In order to ensure that the clamping jaw fixing plate 222 can accurately move in the first direction under the push of the centering cylinder 224, the clamping jaw fixing plate 222 is disposed on the second slide 2252 that slides and moves along the first direction. The second slide 2252 can also make the clamping jaw fixing plate 222 move smoothly and reduce the thrust of the centering cylinder 224.
[0037] In one embodiment, if Figure 5 As shown, the centering jaw 223 includes a first groove 2231 and a second groove concentrically arranged in the second direction, the first groove 2231 is used to accommodate and position the first lens A, and the second groove is used to accommodate and position the second lens B. Considering that the first lens A and the second lens B have different sizes or different outer wall shapes, the first groove 2231 and the second groove are respectively arranged on the centering jaw 223 to position the first lens A and the second lens B, thereby ensuring the concentricity of the two.
[0038] Please refer to Figure 6 and Figure 7 As shown, the carrier mechanism 230 includes a lens carrier 231, a carrier mounting plate 232, a cylinder joint 233 and a UV lamp 234. A first vacuum through hole 2311 is opened in the middle of the lens carrier 231, and a first mounting through hole 2321 and a second vacuum through hole 2322 which are connected to each other are opened on the carrier mounting plate 232. The lens carrier 231 is placed on the carrier mounting plate 232 and is partially located in the first mounting through hole 2321. The first vacuum through hole 2311 and the second vacuum through hole 2322 are connected. The cylinder joint 233 is arranged in the second vacuum through hole 2322, and the UV lamp 234 is arranged corresponding to the first vacuum through hole 2311. It is understandable that the cylinder joint 233 is set in the second vacuum through hole 2322 on the stage mounting plate 232, and the second vacuum through hole 2322 is connected to the first vacuum through hole 2311 of the lens stage 231 through the first mounting through hole 2321. When the cylinder joint 233 is connected to the external vacuum equipment, the first lens A placed on the lens stage 231 can be adsorbed to achieve the positioning and fixation of the first lens A. After the first lens A and the second lens B placed on the lens stage 231 are positioned by glue dot, the UV lamp 234 corresponding to the first vacuum through hole 2311 can cure the glue on the first lens A and the second lens B in time, so as to avoid the misalignment of the first lens A and the second lens B caused by the subsequent separate glue curing, and further improve the concentricity of the first lens A and the second lens B.
[0039] Preferably, the stage mechanism 230 further includes a stage fixing block 235 and a first annular magnet 236, a second mounting through hole 2351 is provided in the middle of the stage fixing block 235, the first annular magnet 236 is disposed in the second mounting through hole 2351, the stage mounting plate 232 is disposed on the stage fixing block 235, and the first mounting through hole 2321 and the second mounting through hole 2351 are connected, and the stage fixing block 235 is mounted on the first mounting plate 221 and is located between the symmetrically disposed centering jaws 223. The stage mounting plate 232 is adsorbed on the stage fixing block 235 by the first annular magnet 236, which facilitates the rapid replacement of different types of stage mounting plates 232 and lens stages 231, thereby improving the applicable scope of the device. The second mounting through hole 2351 on the stage fixing block 235 and the first mounting through hole 2321 on the stage mounting plate 232 are connected, thereby ensuring that the UV lamp 234 can sequentially irradiate the first lens A and the second lens B through the second mounting through hole 2351 and the first mounting through hole 2321. The stage fixing block 235 is mounted on the first mounting plate 221 and located between the symmetrically arranged centering jaws 223, ensuring that the centering jaws 223 can synchronously squeeze the first lens A and the second lens B, thereby improving the concentricity of the first lens A and the second lens B.
[0040] Please refer to Figure 8 As shown, the pressing mechanism 30 further includes a driving module 320 and a mounting post 330. The pressing head module 310 is mounted on the driving module 320. The driving module 320 is mounted on the mounting post 330. The driving module 320 is used to drive the pressing head module 310 to move toward the positioning bearing mechanism 20. The pressing head module 310 can be quickly moved to the bearing mechanism through the driving module 320, that is, quickly adjusted to the top of the first lens A and the second lens B for rough step positioning.
[0041] Please refer to Fig. 9 and Fig.10As shown, the pressure head module 310 includes a lens pressure head 311, a connecting plate 312, a micro pressure gauge 313 and a low friction cylinder 314. The lens pressure head 311 is connected to the bottom of the connecting plate 312, and the low friction cylinder 314 is installed on the top of the connecting plate 312 through the micro pressure gauge 313. The low friction cylinder 314 is used to drive the lens pressure head 311 to move toward the positioning bearing mechanism 20. It should be noted that the low friction cylinder 314 can maintain the push-out state, and its intake pressure is controlled by an electrical proportional valve, which can ensure that the output pressure of the low friction cylinder 314 is constant. The low friction cylinder 314 itself has a very low friction force, which reduces the loss of thrust, so that the output force is closer to the calculated value, thereby ensuring that the push-out amount of the lens pressure head 311 is accurate, and the lens pressure head 311 acts on the first lens A and the second lens B. The pressure is constant, and finally the concentricity of the assembly of the first lens A and the second lens B is improved. A micro pressure gauge 313 is arranged between the low-friction cylinder 314 and the lens press head 311, which can monitor the squeezing force on the lens press head 311 in real time, and then measure the squeezing force acting on the first lens A and the second lens B, to ensure that the thrust of the low-friction cylinder 314 is always monitored during the fitting process to prevent the thrust from being too large or too small to damage the first lens A and the second lens B or causing the first lens A and the second lens B to fail to fit properly.
[0042] In one embodiment, the press head module 310 further includes a press head fixing plate 315 and a third sliding member 316. The connecting plate 312 is movably connected to the press head fixing plate 315 through the third sliding member 316, and the movable direction is the direction in which the lens press head 311 moves toward the positioning bearing mechanism 20. The connecting plate 312 is connected to the driving module through the press head fixing plate 315. The connecting plate 312 on which the lens press head 311 is mounted is connected to the press head fixing plate 315 through the third sliding member 316, so that when the lens press head 311 is over-pressed, the connecting plate 312 can buffer upward to avoid crushing the first lens A and the second lens B, that is, the third sliding member 316 can ensure the accuracy and stability of the movement of the lens press head 311, thereby protecting the first lens A and the second lens B that are in contact with each other.
[0043] Preferably, the press head module 310 further includes a universal damping joint 317, a sleeve 318 and a second annular magnet 319, the universal damping joint 317 is fixed to the bottom of the connecting plate 312, the sleeve 318 is fixed to the bottom of the universal damping joint 317, and the lens press head 311 is arranged on the sleeve 318 through the second annular magnet 319. Among them, the universal damping joint 317 can effectively absorb and reduce the impact force and vibration of the connecting plate 312 during the movement, avoid violent shaking or collision, thereby protecting the safety of the lens press head 311, and ensuring that the lens press head 311 remains stable when squeezing the first lens A and the second lens B. The lens press head 311 is connected to the sleeve 318 through the second annular magnet 319, which can realize the rapid replacement of different types of lens press heads 311, thereby improving the applicability of the device.
