Abstract
Description
Technical Field
[0001] This application relates to the field of optical technology, and in particular to an alignment device and method for multi-faceted array lenses. Background Technology
[0002] With the development of the field of optical imaging, the application of imaging-grade array lenses such as binocular, multi-lens, and compound-eye lenses is becoming increasingly widespread. The traditional lens alignment and adjustment testing device is a lens eccentricity meter, and the fixing device consists of a lens barrel and a retaining ring. The lens is placed on the lens barrel, and after the eccentricity is detected by the eccentricity meter and the required eccentricity value is met, the retaining ring is used to fix it.
[0003] Imaging-grade array lenses, due to limitations in their system detection capabilities, can only be matched with single-target detectors (CCD / CMOS, etc.), resulting in small unit lenses (sizes in the hundreds or even tens of micrometers) and thin, brittle lens substrates (single-sided thickness in the hundreds of micrometers). Higher precision (≤3µm) is required during the alignment, assembly, and bonding of multi-faceted array lenses; direct clamping is not feasible; the process requirements for double-sided and multi-faceted bonding must be met; and automation and mass production technologies are necessary.
[0004] Therefore, existing eccentricity instruments used for alignment can only serve as a reference for single-lens assembly and adjustment. After a single lens in an array of lenses is aligned, other lenses will have rotational misalignment centered on the alignment unit lens, making it impossible to align and adjust the array of lenses simultaneously. Summary of the Invention
[0005] In view of this, the purpose of this application is to provide an alignment device and method for multi-faceted array lenses, which solves the problem of how to align multi-faceted array lenses.
[0006] To achieve one of the aforementioned objectives, this application provides an alignment device for a multi-faceted array lens, comprising:

The projection of the arc surface onto the bottom surface is a concentric arc with the bottom surface. The plane surface is located at the end of the third through hole facing the receiving groove.
[0013] As a further improvement to one embodiment of this application, the first sub-package further includes: The grommets are placed in the through holes. In a pair of through holes, the grommets in one of the through holes are elastic ball-head grommets, and the grommets in the other through hole are aligned with the grommets on the connecting rod.
[0014] As a further improvement to one embodiment of this application, it also includes: The injection hole is formed on the surface of the sub-package and communicates with the cavity containing the multi-faceted array lens.
[0015] As a further improvement of one embodiment of this application, the light source is also used to generate ultraviolet light for the cured colloid; The light source device also includes: A collimating lens and a beam splitter are provided.

[0023] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.
[0024] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by those skilled in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.
[0025] In existing technologies, alignment evaluation for imaging homogenizers is achieved using parallel light and relay light imaging optical paths. However, this method has low accuracy, limited application, and is not suitable for different types of imaging-grade array lenses, such as those used in multi-faceted imaging arrays where two lens arrays exhibit divergent combinations. Another method involves unmarked deep-relief microlens arrays, which utilize deep relief as alignment reference marks. However, this approach increases the complexity of lens array manufacturing, has limited application, and is unsuitable for lens arrays with non-circular aperture designs.
[0026] In summary, none of the existing technologies can solve the requirements for high precision, thin and fragile array lenses, double-sided multi-sided bonding process, and automated mass production during the alignment and bonding of multi-faceted array lenses.
[0027] This application provides an alignment device for a multi-faceted array lens 9, such as... Figure 1As shown, it includes a placement device, an adjustment device, a light source device 5, an imaging device 6, and a control device 7. The placement device includes a placement platform 1 and a packaging component 2 placed on the placement platform 1, such as... Figure 2 As shown, the package 2 includes multiple sub-packages that encapsulate each other, and the multi-faceted array lens 9 is connected to each of the multiple sub-packages. The adjustment device is used to move the sub-packages along a first direction and / or a second direction, and is also used to rotate the sub-packages about the center of the array lens 9 as an axis, so that the multi-faceted array lens 9 in the package 2 is aligned. The first direction and the second direction are perpendicular to and parallel to the placement side of the stage 1. The light source device 5 and the imaging device 6 are both opposite to the placement side of the stage 1. The light source 501 in the light source device 5 is used to provide imaging light for the imaging device 6. The control device 7 is connected to the adjustment device and the imaging device 6 respectively, and is used to receive the image from the imaging device 6, calculate the deviation between the multi-faceted array lenses 9, and control the movement of the adjustment device according to the deviation.
[0028] Specifically, the encapsulation component 2 is placed on the platform 1 of the placement device, and the light from the light source device 5 and the imaging device 6 is directed toward the platform 1.
[0029] In a specific implementation, the storage device also includes an electric slide controller and a six-axis loading adjustment platform. The electric slide controller is used to control the six-axis loading adjustment platform to move upward in the first direction, the second direction, and the third direction, rotate in the direction about the center axis, and tilt in both directions. The storage platform 1 is located on top of the six-axis loading adjustment platform.
[0030] Specifically, the multi-faceted array lens 9 is connected to the sub-package. By moving the relative positions between the sub-packages, the relative positions between the multi-faceted array lens 9 can be changed until the multi-faceted array lens 9 is aligned.
[0031] Specifically, the relative positions between the sub-packages are adjusted using an adjustment device. The adjustment device has three adjustment directions: translation in the first direction, translation in the second direction, and rotation about the center axis. Package 2 is placed on the stage 1, so the position of package 2 remains unchanged in the direction perpendicular to the stage 1, while the first direction, the second direction, and the rotation surface are all parallel to the placement surface of the stage 1.
[0032] Specifically, the control device 7 is connected to the imaging device 6 and the adjustment device via data cables. The imaging device 6 transmits the image from the multi-faceted array lens 9 back to the control device 7. The control device 7 calculates the deviation value between the multi-faceted array lenses 9, obtains the direction and value of the required movement between multiple sub-packages based on the deviation value, and transmits the direction and value to the adjustment device.
[0033] Specifically, the imaging device 6 captures images of the multi-faceted array lens 9 in the package 2 on the placement side relative to the stage 1, and the light source device 5 provides light to the imaging device 6.
[0034] In one possible implementation of this application, the light source device 5 includes a light source 501, a collimating lens 502, and a beam splitter 503. The light source 501 is also used to generate ultraviolet light for curing the colloid. The collimating lens 502 is arranged in the light path of the light source 501, and the beam splitter 503 is arranged in the light path transmitted through the collimating lens 502 and is opposite to the stage 1. The imaging device 6 includes a camera 601 and a microscopic zoom monocular 602, with the camera 601 facing the placement side of the stage 1.
[0035] Specifically, the light source 501 used for imaging includes LED lamps, halogen tungsten lamps, and xenon lamps, etc. The light source 501 used for imaging and the light source 501 used for curing are switched by a switch. During imaging, the light source provides imaging light. After the adhesive is applied, the ultraviolet light from the curing light source 501 is used to cure the adhesive. Light is emitted through a Y-shaped optical fiber and a filter. The filter is used in conjunction with the light source 501. If it is necessary to filter out ultraviolet light, a long-pass filter LPF400nm can be added to reduce the influence of ultraviolet light on the light source 501 during the adhesive application process. The light emitted by the light source 501 is oriented after passing through the collimating lens 502. After passing through the collimating lens 502, the light is reflected by the beam splitter 503, so that the light enters the array lens 9 uniformly.
[0036] In one possible implementation of this application, such as Figures 2-5 As shown, the package 2 includes a first sub-package 3 and a second sub-package 4, with at least one array lens 9 connected to each of the opposing surfaces of the first sub-package 3 and the second sub-package 4; the adjustment device is used to move the first sub-package 3 or the second sub-package 4 so that the array lens 9 on the first sub-package 3 is aligned with the array lens 9 on the second sub-package 4.
[0037] Specifically, the package 2 includes a first sub-package 3 and a second sub-package 4. After the multi-faceted array lens 9 is packaged, it is located between the first sub-package 3 and the second sub-package 4. The adjustment device only needs to move one of the first sub-package 3 or the second sub-package 4, and the array lens 9 connected to it can move relative to the other lens to achieve alignment. By using the first sub-package 3 and the second sub-package 4, the array lens 9 can be operated indirectly, improving safety and adjustability.
[0038] In a specific implementation, one array lens 9 is encapsulated on each of the first sub-package 3 and the second sub-package 4, and the package 2 contains two array lenses 9. In other implementations, the first sub-package 3 or the second sub-package 4 encapsulates aligned two array lenses 9, and the package 2 contains three array lenses 9.
[0039] In one possible implementation of this application, such as Figure 4As shown, the first sub-package 3 includes a receiving groove 301, and a through hole is provided on the groove wall of the receiving groove 301. In the packaged state, the second sub-package 4 is placed in the receiving groove 301.
[0040] In one possible implementation of this application, the adjustment device includes a drive member and a connecting rod, the drive member being used to drive the connecting rod to move in the through hole to push the second sub-encapsulation layer to move.
[0041] Specifically, the second sub-package 4 is placed in the receiving groove 301 of the first sub-package 3 and can move in the receiving groove 301. After the connecting rod passes through the groove wall of the receiving groove 301, it applies force to the second sub-package 4 to make the second sub-package 4 move. The receiving groove 301 and the through hole limit the movement direction of the second sub-package 4, which improves the accuracy of adjustment.
[0042] In one possible implementation of this application, such as Figure 4 and Figure 5 As shown, X is the first direction and Y is the second direction. The through holes include a first through hole pair 302, a second through hole pair 303, and a third through hole pair 304. The first through hole pair 302 is arranged opposite to each other in the first direction, and the axis of the first through hole pair 302 is the line of symmetry of the first sub-package 3 along the first direction. The second through hole pair 303 is arranged opposite to each other in the second direction, and the axis of the second through hole pair 303 is the line of symmetry of the first sub-package 3 along the second direction. The third through hole pair 304 is arranged opposite to each other, and the axis of the third through hole pair 304 is the line of asymmetry of the first sub-package 3.
[0043] Specifically, a connecting rod extends into the first through-hole pair 302 to push the second sub-package 4, causing the second sub-package layer to translate in the first direction, thereby adjusting the position of the array lens 9 in the first direction. A connecting rod extends into the second through-hole pair 303 to push the second sub-package layer, causing the second sub-package layer to translate in the second direction, thereby adjusting the position of the array lens 9 in the second direction. A connecting rod extends into the third through-hole pair 304, the axis of which is inclined relative to the line of symmetry, achieving the effect of rotation around a center.
[0044] In one possible implementation of this application, such as Figure 6 As shown, the first sub-package 3 is a cylindrical structure, with a receiving groove 301 opened on the bottom surface of the cylindrical structure; the side wall of the receiving groove 301 includes an arc surface and a plane, the projection of the arc surface on the bottom surface is a concentric arc with the bottom surface, and the plane is located at the end of the third through hole facing the receiving groove 301.
[0045] Specifically, the main part of the projection of the receiving groove 301 is the concentric circle of the bottom surface of the first sub-encapsulation layer. The part opposite to the third through hole pair 304 is set as a plane. Correspondingly, the second sub-encapsulation 4 is also set as a plane at the position corresponding to the plane, so as to abut against the force exerted by the connecting rod in the third through hole pair 304.
[0046] In other possible implementations, the first sub-package 3 and the second sub-package 4 are cubic prisms, the axis of the first through hole pair 302 is along the length direction of the bottom surface, the axis of the second through hole pair 303 is along the width direction of the bottom surface, and the axis of the third through hole pair 304 is parallel to the diagonal direction of the bottom surface.
[0047] In one possible implementation of this application, the first sub-package 3 further includes a grommet screw, which is placed in a through hole. In a pair of through holes, the grommet screw in one of the through holes is a flexible ball-head grommet screw, and the grommet screw in the other through hole is aligned with the grommet screw on the connecting rod.
[0048] Specifically, the elastic ball-head fin screw is a composite fastener integrating a spring, steel column, and thread. It can achieve elastic dynamic positioning, and the elastic spherical contact will not scratch or crush the surface of precision workpieces, reducing mechanical impact. The connecting rod applies force or retracts in one of the through holes of the through hole pair. When force is applied, the second sub-encapsulation 4 moves towards the other through hole. When retracted, the elastic ball-head fin screw in the other through hole pushes the second sub-encapsulation layer back, moving it in the opposite direction.
[0049] In one possible implementation of this application, such as Figure 2 and Figure 6 As shown, the alignment device also includes a glue injection hole 8, which is opened on the surface of the sub-package and communicates with the chamber that houses the multi-faceted array lens 9.
[0050] Specifically, after the multi-faceted array lens 9 is aligned, adhesive is injected between the first sub-package 3 and the second sub-package 4 through the injection hole 8, and the cured adhesive will form an array lens 9 sample.
[0051] Another embodiment of this application discloses an alignment method for a multi-faceted array lens, which is applied to the alignment device of the above embodiments, such as... Figure 7 As shown, the method includes: Step S100: Turn on the light source device and the imaging device.
[0052] Specifically, the imaging light from the light source device is turned on to provide illumination for imaging.
[0053] Step S200: The multi-faceted array lens is encapsulated on the package and the multi-faceted array lens is roughly aligned.
[0054] Specifically, the adjustment stage extension arm is inserted into the through hole to adjust the position of the array lens, so that the multi-faceted array lens is aligned with the naked eye, thus achieving coarse alignment.
[0055] In step S300, the control device activates the microscopic imaging scanning mode of the light source device and the imaging device, focuses the imaging on the multi-faceted array lens, and calculates the offset value between the multi-faceted array lenses.
[0056] Specifically, such as Figure 8 As shown in Figure (a), after microscopic imaging, two array images are displayed in the image, with an offset between them. Figure (b) shows that after moving the first or second sub-package, the offset between the two array images is gradually eliminated until the state shown in Figure (c) is reached, where the two array images overlap. By eliminating the offset between the two array images, the alignment of the multi-faceted array lens is achieved. By calculating the offset value using the microscopic imaging image, the alignment accuracy is greatly improved.
[0057] In one possible implementation of this application, step S300 includes: Step S310: Determine the first absolute center point O' and the first corner centers A' and B' on the image formed by one of the array lenses.
[0058] Step S320: Determine the second absolute center point O and the second corner centers A and B on the image formed by the other array lens.
[0059] Step S330: Establish a coordinate system with the first absolute center point as the center, and determine the coordinate values of the first corner center, the second absolute center point, and the second corner center.
[0060] Step S340: Calculate the translational offset values of the array lens in the first and second directions according to the following formula: ; Where m is the comprehensive motion mapping ratio coefficient between imaging magnification and electric slide step, and X0 and Y0 are the coordinate values of the second absolute center point.
[0061] Step S350: Calculate the angular offset of the array lens on the central axis according to the following formula: ; Where n is the comprehensive rotation mapping ratio coefficient of imaging magnification and electric slide step, ABS is the vector length processing, X1 and Y1 are the coordinate values of the first corner center A', and X3 and Y3 are the coordinate values of the second corner center A.
[0062] It should be noted that the sign of the vector in the above formula is determined by whether the vector is counterclockwise (θ-axis electric slide step increase) or clockwise (θ-axis electric slide step decrease) in the coordinate system.
[0063] In step S400, the control device controls the adjustment device to move the sub-package according to the offset value so that the multi-faceted array lens is aligned.
[0064] Step S500: Apply adhesive into the injection hole and cure it to form an array lens sample.
[0065] Specifically, after the multi-faceted array lens is aligned and fixed, the fixing holes are secured with screws, forming a glue-filling cavity between the aligned array lens and the mechanical components. UV glue is injected into the cavity through the glue-filling holes, and the glue flow is observed under a microscope to ensure that the glue fills the cavity completely without air bubbles. The imaging light is then switched to ultraviolet light to cure the UV glue. After curing, the light source is switched back to illumination mode, and alignment errors are observed and tested. If no errors are found, the sample is removed.
