Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of camera assembly, and particularly relates to a parallel light assembly and a camera alignment device. BACKGROUND

[0002] The lens of the vehicle-mounted camera and the image sensor should be located on the lens optical axis, and the image sensor is perpendicular to the optical axis. Therefore, during the assembly of the camera, the assembly precision of each component needs to be ensured. For this purpose, an active alignment (AA) device is used in the prior art to automatically align the lens and the base (including the image sensor). In order to meet the demand for analog light sources when the camera detects high-quality and large-angle images, a collimator is used instead of a plane light source as an analog light source for camera alignment.

[0003] For example, Chinese patent CN115592376A discloses a multi-lens camera assembly device, and the alignment device includes a plurality of second light pipes. Each second light pipe is connected to the fixed frame through a micro-motion platform, a sliding block, a guide rail and a fixed plate connected in sequence. The second light pipe can be adjusted along the guide rail and can be finely adjusted along the two arc surfaces through the micro-motion platform, so as to realize the adjustment of the second light pipe. During the alignment operation, the plurality of second light pipes need to be adjusted to be compatible with the lens and the base to be assembled, that is, the light emitting ends of the plurality of second light pipes are tangent to the spherical surface of a virtual sphere with the lens and the base as the spherical center. However, since there are errors in the machining and assembly of each component in the lens and the base, the actual size of the sensor image deviates from the theoretical size. The second light pipe of the above-mentioned camera assembly device has a small adjustable range, cannot compensate for the above-mentioned errors by adjusting the position, cannot be adjusted to be compatible with the lens and the base to be assembled, and thus affects the accuracy of the alignment of the lens and the base.

[0004] Therefore, there is an urgent need for a parallel light assembly and a camera alignment device to solve the above-mentioned technical problems. SUMMARY

[0052] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a parallel light assembly 2, including multiple light source assemblies 20. Each light source assembly 20 includes an arc-shaped bracket 21, a connecting structure 22, a parallel light tube adjustment assembly 23, and a parallel light tube 24. The arc-shaped bracket 21 can be mounted on a base frame 1, such that the arc-shaped bracket 21 of the multiple light source assemblies 20 is located on the surface of a first virtual sphere with the product to be assembled 10 as its center. The connecting structure 22 is movably connected to the inner side of the arc-shaped bracket 21 along its extension direction. The parallel light tube adjustment assembly 23 is connected to the connecting structure 22. The parallel light tube 24 is connected to the parallel light tube adjustment assembly 23. The parallel light tube adjustment assembly 23 can adjust the position of the parallel light tube 24 in the axial and radial directions, so that the position of the multiple parallel light tubes 24 is adapted to the product to be assembled 10.

[0054] It should be noted that the product to be assembled 10 includes a lens and a base.

[0055] Specifically, during the alignment operation, the collimator 24 needs to be adjusted to its proper position so that the simulated light source formed by multiple collimators 24 has a wide range of adaptability and good applicability, providing a comprehensive simulated light source for the alignment and assembly of the lens and the base. That is, the light-emitting ends of multiple collimators 24 are tangent to the surface of a second virtual sphere with the base as its center. The diameter of the second virtual sphere is the set working distance. Moreover, the side length ratio of the pattern formed by the sequential connection of multiple collimators 24 needs to meet the sensor image size requirements, so as to form the simulated light source required by the lens and the base at the working part. After the simulated light source is adjusted, the position of the lens is moved. As the relative position between the lens and the base changes, the image quality displayed by the lens changes continuously. The position of the lens when the image quality is best is selected, and the lens is fixed to the base.

[0056] The parallel light assembly 2 provided in this embodiment has a connecting structure 22 movably connected to the inner side of the arc-shaped support 21 along the extension direction of the arc-shaped support 21. Therefore, the position of the parallel light tube 24 can be adjusted by adjusting the position of the connecting structure 22 in the extension direction of the arc-shaped support 21. A planar light tube adjustment assembly 23 is connected between the parallel light tube 24 and the connecting structure 22. The planar light tube adjustment assembly 23 can adjust the axial and radial positions of the parallel light tube 24, increasing the adjustable range of the parallel light tube 24 so that the positions of multiple parallel light tubes 24 are adapted to the product 10 to be assembled. Therefore, the parallel light assembly 2 provided in this embodiment is used to effectively compensate for errors caused by processing and assembly of the product 10 to be assembled, and can be adjusted to be adapted to the product 10 to be assembled, thereby improving the assembly accuracy.

[0057] Specifically, the collimator adjustment assembly 23 includes an axial adjustment assembly 231 and a radial adjustment assembly 232. The axial adjustment assembly 231 is connected to the connecting structure 22, and the radial adjustment assembly 232 is connected to the axial adjustment assembly 231. The collimator 24 is connected to the radial adjustment assembly 232. The axial adjustment assembly 231 can adjust the movement of the radial adjustment assembly 232 to drive the collimator 24 to move axially. The radial adjustment assembly 232 can adjust the movement of the collimator 24 radially. The arrangement of the axial adjustment assembly 231 and the radial adjustment assembly 232 realizes the adjustment of the axial and radial positions of the collimator 24.

[0058] Specifically, such as Figure 2 and Figure 3As shown, the axial adjustment assembly 231 includes a connecting block 2311, a first adjusting bracket 2312, and a first adjusting bolt 2313. The connecting block 2311 is connected to the connecting structure 22. The first adjusting bracket 2312 is slidably connected to the connecting block 2311 along the axial direction of the parallel light tube 24. The first adjusting bolt 2313 extends along the axial direction of the parallel light tube 24, with one end rotatably connected to the connecting block 2311 about its own axis, and the other end threadedly connected to the first adjusting bracket 2312. By turning the first adjusting bolt 2313, the first adjusting bracket 2312 can be driven to move relative to the connecting block 2311 along the axial direction of the parallel light tube 24, thereby causing the parallel light tube 24 to move closer to or further away from the working part.

[0059] More specifically, of the first adjusting bracket 2312 and the connecting block 2311, one is provided with a first sliding protrusion 23121, and the other is provided with a first sliding groove 23111 extending along the axial direction of the parallel light tube 24. The first sliding protrusion 23121 and the first sliding groove 23111 are slidably connected. The cooperation of the first sliding protrusion 23121 and the first sliding groove 23111 realizes the sliding connection between the first adjusting bracket 2312 and the connecting block 2311.

[0060] Specifically, such as Figure 2 and Figure 3 As shown, the radial adjustment assembly 232 includes a second adjustment bracket 2321 and a second adjustment bolt 2322. The second adjustment bracket 2321 is slidably connected to the first adjustment bracket 2312 along the radial direction of the collimator 24, and the collimator 24 is connected to the second adjustment bracket 2321. The second adjustment bolt 2322 extends radially along the collimator 24, with one end rotatably connected to the first adjustment bracket 2312 about its own axis, and the other end threadedly connected to the second adjustment bracket 2321. By turning the second adjustment bolt 2322, the second adjustment bracket 2321 can be driven to move radially relative to the first adjustment bracket 2312 along the collimator 24, thereby adjusting the distance between the multiple collimators 24.

[0061] More specifically, of the first adjusting bracket 2312 and the second adjusting bracket 2321, one is provided with a second sliding protrusion, and the other is provided with a second sliding groove 23211 extending radially along the parallel light tube 24. The second sliding protrusion and the second sliding groove 23211 are slidably connected. The cooperation of the second sliding protrusion and the second sliding groove 23211 realizes the sliding connection between the first adjusting bracket 2312 and the second adjusting bracket 2321.

[0062] Specifically, such as Figure 2 and Figure 4As shown, the collimating light assembly 2 also includes a mounting structure 25, which is connected to the collimating light tube adjustment assembly 23. The collimating light tube 24 is rotatably connected to the mounting structure 25 around its own axis. The mounting structure 25 allows the collimating light tube 24 to rotate around its own axis, thereby aligning the internal chart angle of the collimating light tube 24. In this embodiment, the mounting structure 25 is connected to the second adjustment frame 2321.

[0063] More specifically, the mounting structure 25 includes multiple rotating connecting blocks 251, which are connected to the collimator adjustment assembly 23. The multiple rotating connecting blocks 251 are evenly distributed around the axis of the collimator 24. Each rotating connecting block 251 has an arc-shaped groove 2511, and the circumferential flange at the tail end of the collimator 24 is disposed within the arc-shaped groove 2511. This structure achieves a rotating connection between the mounting structure 25 and the collimator 24. In this embodiment, the rotating connecting block 251 is connected to the second adjustment frame 2321.

[0064] More specifically, the rotating connecting block 251 has an arc-shaped through groove 2512, and at least one of the arc-shaped through grooves 2512 of the rotating connecting block 251 is fitted with a locking bolt 252, which is threaded onto the circumferential flange. The engagement of the locking bolt 252 and the arc-shaped through groove 2512 locks the parallel light tube 24 at a suitable angle, thus maintaining the angle of the parallel light tube 24.

[0065] Specifically, the collimating light assembly 2 also includes an angle adjustment slide 26, which is mounted on the connecting structure 22. The collimating light tube adjustment assembly 23 is connected to the output end of the angle adjustment slide 26. The angle adjustment slide 26 is used to adjust the position of the collimating light tube 24 within two cylindrical arc surfaces, the central axes of which are perpendicular to each other. The angle adjustment slide 26 enables the adjustment of the angle of the collimating light tube 24. The angle adjustment slide 26 is a conventional device for fine-tuning angles in the prior art, and its specific structure and working principle can be found in the prior art, and will not be described in detail here. In this embodiment, the connecting block 2311 is connected to the output end of the angle adjustment slide 26.

[0066] Specifically, such as Figure 2 As shown, the light source assembly 20 also includes an L-shaped connector 27, which is connected to the arc-shaped bracket 21 and is used to connect to the base frame 1.

[0067] Specifically, the connecting structure 22 is slidably connected to the arc-shaped support 21 via the mutually sliding arc-shaped slide rail 28 and the sliding block. The arc-shaped support 21 is provided with an angle scale along its extension direction, and the connecting structure 22 is provided with a pointer that points to the angle scale, so as to control the change of angle of the collimator 24 as it slides along the arc-shaped support 21.

[0068] More specifically, the connecting structure 22 is U-shaped, and the arc-shaped bracket 21 passes through the U-shaped groove of the connecting structure 22. A sliding block is connected to the inner side of one side plate of the arc-shaped bracket 21, and the locking screw is locked onto the arc-shaped bracket 21 through the other side plate. Multiple mounting through holes are evenly arranged on the arc-shaped bracket 21 along the extension direction, and the locking screw can be selectively connected to one of the mounting through holes to adjust the position of the collimator 24.

[0069] like Figure 1 and Figure 2 As shown, this embodiment also provides a camera alignment device, which includes a base frame 1 and the aforementioned parallel light assembly 2. The base frame 1 has a working part for supporting the product 10 to be assembled. The arc-shaped supports 21 of multiple light source components 20 of the parallel light assembly 2 are mounted on the base frame 1, and the multiple arc-shaped supports 21 are located on the surface of a first virtual sphere with the product 10 to be assembled as its center. The camera alignment device provided in this embodiment provides a comprehensive simulated light source for camera alignment and assembly. Through more precise adjustment of the parallel light source, it effectively compensates for errors caused by processing and assembly of the product 10 to be assembled, and can adjust the parallel light source to be compatible with the product 10 to be assembled, thereby improving the accuracy of assembly.

[0070] Specifically, the camera alignment device provided in this embodiment further includes a pattern card assembly 3 and a repeater lens assembly 4. The pattern card assembly 3 is disposed on the base frame 1 and located above the parallel light assembly 2, and is used for alignment using the test pattern card 31 of the pattern card assembly 3. The repeater lens assembly 4 is disposed on the base frame 1 and located below the pattern card assembly 3, and is used for optical environment simulation using the repeater lens 41 of the repeater lens assembly 4. The placement of the pattern card assembly 3 helps to improve the accuracy of alignment; the use of the repeater lens 41 for simulation measurement helps to reduce the overall size of the device.

[0071] Specifically, during the alignment operation, the center of the test chart 31 and the center of the second virtual sphere are vertically aligned; the center of the relay mirror 41 and the center of the second virtual sphere are vertically aligned, that is, the center of the test chart 31 and the center of the relay mirror 41 are vertically aligned with the center of the second virtual sphere.

[0072] like Figure 1 and Figure 2 As shown, the base frame 1 includes a support base 11, four support columns 12, and a top plate 13. The four support columns 12 are vertically connected to the top of the support base 11, and are respectively located at the four corners of a rectangle. The top plate 13 is connected to the top of the four support columns 12. An arc-shaped bracket 21 is installed on the top of the support base 11, a repeater mirror assembly 4 is disposed on the support base 11, and a card assembly 3 is connected to the four support columns 12.

[0073] Specifically, such asFigure 1 and Figure 5 As shown, the base frame 1 is provided with multiple mounting parts 111, which are divided into multiple groups. The parallel light component 2 can be selectively mounted on one of the groups of mounting parts 111, and multiple arc-shaped brackets 21 are connected one-to-one to the multiple mounting parts 111 in that group. The sequential connection of the multiple mounting parts 111 in the same group forms a rectangle, and the length-to-width ratio of the rectangle formed by any two groups of mounting parts 111 is different. This arrangement allows for adaptation to different models of products 10 to be assembled by changing the mounting position of the parallel light component 2, thus improving applicability. In this embodiment, the mounting part 111 is located on the top of the support base 11.

[0074] More specifically, the mounting section 111 includes multiple mounting holes, and the L-shaped connector 27 is connected to the multiple mounting holes by the same number of fasteners, thereby realizing the installation of the parallel light assembly 2 on the mounting section 111.

[0075] In this embodiment, four light source assemblies 20 are provided. Each group of mounting parts 111 includes four mounting parts 111. The four mounting parts 111 in the same group are connected in sequence to form a rectangle, and the four mounting parts 111 are the four corners of the rectangle. Specifically, three groups of mounting parts 111 are provided on the base frame 1, and the length-to-width ratio of the rectangles formed by the three groups of mounting parts 111 are 1:1, 4:3 and 16:9 respectively.

[0076] Specifically, such as Figure 6 and Figure 7 As shown, the repeater assembly 4 includes a position adjustment component 42, a repeater support plate 43, and a repeater 41. The position adjustment component 42 is disposed within or mounted on the base frame 1. One end of the repeater support plate 43 is connected to the position adjustment component 42, which can adjust the position of the repeater support plate 43 in two mutually perpendicular first horizontal directions, second horizontal directions, and vertical directions. The other end of the repeater support plate 43 has a positioning through hole 431 extending vertically. The lens portion 412 of the repeater 41 passes downward through the positioning through hole 431, and the main body portion 411 of the repeater 41 abuts against the top surface of the repeater support plate 43. The diameter of the positioning through hole 431 is larger than the diameter of the lens portion 412 by a set length, so that the repeater 41 can move relative to the repeater support plate 43 within the plane of the repeater support plate 43.

[0077] The position adjustment component 42 can adjust the position of the repeater lens support plate 43 in two mutually perpendicular first horizontal directions, second horizontal directions, and vertical directions, thereby achieving coarse adjustment of the position of the repeater lens 41 in the first horizontal direction, second horizontal direction, and vertical direction. The repeater lens 41 is placed on the repeater lens support plate 43, with the lens part 412 of the repeater lens 41 facing downward and passing through the positioning through hole 431 on the repeater lens support plate 43. The main body part 411 of the repeater lens 41 abuts against the top surface of the repeater lens support plate 43, and the diameter of the positioning through hole 431 is larger than the diameter of the lens part 412 by a set length. Therefore, the repeater lens 41 can move relative to the repeater lens support plate 43 within the plane where the repeater lens support plate 43 is located. Fine adjustment of the repeater lens 41 can be achieved by moving the repeater lens 41. Therefore, this embodiment can perform fine adjustment of the position of the repeater lens 41, thereby ensuring that the repeater lens 41 is accurately aligned with the lens and the base, and thus ensuring the accuracy of the camera assembly.

[0078] Specifically, see [link to relevant documentation] Figure 6 and Figure 7 On the top surface of the relay mirror support plate 43, a plurality of circumferentially evenly distributed support members 44 are provided along the outer edge of the positioning through hole 431. The support members 44 extend along the axial direction of the positioning through hole 431, and the top end of the support member 44 smoothly contacts the main body 411. The support members 44 can adjust the horizontal height of the teleconverter 41 to achieve the purpose of fine adjustment of the teleconverter 41, so that the center of the teleconverter 41 is aligned with the center of the product 10 to be assembled.

[0079] More specifically, such as Figure 7 and Figure 8 As shown, the support member 44 includes a column 441 and a ball bearing 442 connected to one end of the column 441. The column 441 is connected to the repeater mirror support plate 43, and the ball bearing 442 contacts the main body 411. The column 441 is used to support the ball bearing 442, achieving smooth contact between the ball bearing 442 and the main body 411 of the repeater mirror 41. The outer wall of the column 441 is provided with threads, and the height of the support member 44 can be adjusted by rotating the column 441.

[0080] Optionally, the ball bearing 442 is fixedly connected to the column 441, or the ball bearing 442 is rotatably connected to the column 441.

[0081] Specifically, such as Figure 6As shown, the position adjustment assembly 42 includes a support base 421, a vertical adjustment assembly 422, a connecting plate 423, and a horizontal adjustment assembly 424. The support base 421 is disposed within or connected to the base frame 1; the vertical adjustment assembly 422 is connected to the support base 421; one end of the connecting plate 423 is connected to the vertical adjustment assembly 422; the horizontal adjustment assembly 424 is connected to the other end of the connecting plate 423. The vertical adjustment assembly 422 can adjust the position of the connecting plate 423 in the vertical direction. The repeater lens carrier plate 43 is connected to the horizontal adjustment assembly 424. The horizontal adjustment assembly 424 can adjust the position of the repeater lens carrier plate 43 in the first horizontal direction and the second horizontal direction.

[0082] More specifically, such as Figure 7 As shown, the vertical adjustment assembly 422 includes a repeater adjustment bolt 4221, which extends vertically. One end of the repeater adjustment bolt 4221 is rotatably connected to the connecting plate 423 around its own axis, and the other end is threadedly connected to the support base 421. When the repeater adjustment bolt 4221 rotates in the forward direction, it screws downward into the support base 421, causing the connecting plate 423 to move downward. When the repeater adjustment bolt 4221 rotates in the reverse direction, it screws upward out of the support base 421, causing the connecting plate 423 to move upward, thereby realizing the vertical adjustment of the support base 421.

[0083] Specifically, the horizontal adjustment assembly 424 includes a linear slide 4241, which is mounted on the connecting plate 423. The repeater mirror support plate 43 is connected to the linear slide 4241, and the linear slide 4241 can drive the repeater mirror support plate 43 to move in a first horizontal direction and a second horizontal direction. The linear slide 4241 enables the adjustment of the position of the repeater mirror 41 in the horizontal plane. The linear slide 4241 is a conventional device for position adjustment in the prior art, and its specific structure and working principle can be found in the prior art, and will not be described in detail here.

[0084] Specifically, of the connecting plate 423 and the support base 421, one is provided with a slider 4231, and the other is provided with a groove 4211 extending in the vertical direction. The slider 4231 is slidably connected to the groove 4211. The cooperation between the slider 4231 and the groove 4211 realizes the sliding connection between the connecting plate 423 and the support base 421.

[0085] In this embodiment, the slide groove 4211 is formed on the support base 421, and the slider 4231 is disposed on the connecting plate 423.

[0086] Specifically, at least two fine-tuning threaded parts 45 are threadedly connected to the repeater lens support plate 43. These at least two fine-tuning threaded parts 45 are sequentially spaced along the circumference of the positioning through hole 431, extending radially along the positioning through hole 431. One end of each fine-tuning threaded part 45 extends into the positioning through hole 431 and abuts against the lens portion 412, while the other end protrudes outward for screwing. By screwing into and abutting against the lens portion 412 of the repeater lens 41, the fine-tuning threaded parts 45 drive the repeater lens 41 to shift its position. Simultaneously, after the position is adjusted, the at least two fine-tuning threaded parts 45 press firmly against the lens portion 412, maintaining the position of the repeater lens 41.

[0087] Specifically, such as Figures 9 to 12 As shown, the pattern assembly 3 includes a planar light source 32, a test pattern 31, and an optical glass 33 stacked from top to bottom. It also includes a mounting frame 34 and a centering adjustment component 35. The mounting frame 34 is arranged around the planar light source 32, the test pattern 31, and the optical glass 33. The mounting frame 34 is installed on the base frame 1 and is located above the working part. The centering adjustment component 35 is disposed on the mounting frame 34 and is used to adjust the relative position of the test pattern 31 and the planar light source 32 so that the test pattern 31 is located at the physical center of the planar light source 32.

[0088] In this embodiment, the optical glass 33 is optical glass, and the test pattern card 31 is bonded to the upper surface of the optical glass 33 with adhesive tape. The optical glass 33 not only fixes the test pattern card 31, but also ensures that the light from the planar light source 32 passes through smoothly.

[0089] In this embodiment, the planar light source 32, test pattern 31, and optical glass 33 of the pattern assembly 3 are disposed within a mounting frame 34. A centering adjustment component 35 is provided on the mounting frame 34. The centering adjustment component 35 is used to adjust the relative position of the test pattern 31 and the planar light source 32 so that the test pattern 31 is located at the physical center of the planar light source 32. Therefore, the pattern assembly 3 provided in this embodiment improves the convenience of adjusting the relative position of the planar light source 32 and the test pattern 31, reduces maintenance costs, and improves the alignment accuracy of the lens and the base.

[0090] Specifically, such as Figure 9 As shown, the centering adjustment component 35 includes a positioning structure 351 and an adjustment structure 352. Both the positioning structure 351 and the adjustment structure 352 are mounted on the mounting frame 34. The positioning structure 351 is used to limit the position of the planar light source 32, and the adjustment structure 352 is used to adjust the position of the optical glass 33. The positioning structure 351 limits the position of the planar light source 32, preventing the planar light source 32 from shifting during the movement of the optical glass 33, thus avoiding affecting the adjustment of their relative positions.

[0091] Specifically, such as Figure 9and Figure 10 As shown, the adjustment structure 352 includes multiple adjustment bolts 3521. The adjustment bolts 3521 are threaded through the frame plate of the mounting frame 34. The multiple adjustment bolts 3521 are spaced apart sequentially along the circumference of the mounting frame 34. The heads of the adjustment bolts 3521 are located on the outer side of the mounting frame 34, and the tails of the adjustment bolts 3521 extend into the inner side of the mounting frame 34 and abut against the circumferential sidewall of the optical glass 33. The adjustment bolts 3521 are screwed into the mounting frame 34 to shift against the optical glass 33.

[0092] More specifically, a flexible protective layer 3522 covers the end face of the adjusting bolt 3521 that abuts against the optical glass 33. The flexible protective layer 3522 is used to protect the optical glass 33. The flexible protective layer 3522 is formed by overmolding with TPE soft rubber material.

[0093] Specifically, the positioning structure 351 includes multiple positioning bolts 3511. The positioning bolts 3511 are threaded through the frame plate of the mounting frame 34. The multiple positioning bolts 3511 are spaced apart sequentially along the circumference of the mounting frame 34. The heads of the positioning bolts 3511 are located on the outer side of the mounting frame 34, and the tails of the positioning bolts 3511 extend into the inner side of the mounting frame 34 and abut against the circumferential sidewall of the planar light source 32. The positioning bolts 3511 abut against the circumferential sidewall of the planar light source 32, limiting the position of the planar light source 32 and preventing the planar light source 32 from shifting when the optical glass 33 moves, ensuring that the optical glass 33 can move relative to the planar light source 32. Furthermore, if the position of the planar light source 32 is inaccurate, the position of the planar light source 32 can be adjusted by tightening the positioning bolts 3511 until its center is vertically aligned with the center of the product 10 to be assembled on the working part, ensuring the accurate position of the planar light source 32.

[0094] Specifically, such as Figures 9 to 11 As shown, the mounting frame 34 has a rectangular structure, including two opposing first frame plates 341 and two opposing second frame plates 342. A first support portion 3411 protrudes from the inner wall of the first frame plate 341 and / or the second frame plate 342. An optical glass 33 is disposed inside the first frame plate 341 and the second frame plate 342 and placed on the first support portion 3411. A second support portion 3412 protrudes from the inner wall of the first frame plate 341 and / or the second frame plate 342. A fixing groove 3413 is formed between the first support portion 3411 and the second support portion 3412 on the same first frame plate 341 and / or the second frame plate 342. The edge of the optical glass 33 is engaged within the fixing groove 3413, and the planar light source 32 is placed on the second support portion 3412. The first support portion 3411 and the second support portion 3412 are used to support the optical glass 33 and the planar light source 32, respectively.

[0095] like Figure 10 andFigure 11 As shown, in this embodiment, each of the two first frame plates 341 is provided with a first support portion 3411 and a second support portion 3412, i.e., a fixing groove 3413 is provided on the first frame plate 341. Each of the two first frame plates 341 is provided with a positioning bolt 3511 and an adjusting bolt 3521. The tail end of the adjusting bolt 3521 extends into the fixing groove 3413 and abuts against the circumferential sidewall of the optical glass 33. There is a gap between the circumferential sidewall of the optical glass 33 and the bottom wall of the fixing groove 3413, providing space for the optical glass 33 to move. The second frame plates 342 are not provided with a first support portion 3411, a second support portion 3412, or a positioning bolt 3511. Each of the two second frame plates 342 is provided with an adjusting bolt 3521. The circumferential sidewall of the planar light source 32 directly abuts against the second frame plate 342. There is a gap between the circumferential sidewall of the optical glass 33 and the second frame plate 342, providing space for the optical glass 33 to move.

[0096] Specifically, such as Figure 1 and Figure 9 As shown, the test chart assembly 3 also includes a carrier plate 36 and a leveling assembly 37. The carrier plate 36 is connected to the base frame 1, the leveling assembly 37 is disposed on the carrier plate 36, and the mounting frame 34 is disposed on the leveling assembly 37. The leveling assembly 37 can adjust the levelness of the mounting frame 34 so that the test chart 31 and the planar light source 32 are both in the horizontal plane.

[0097] The pattern assembly 3 provided in this embodiment has a mounting frame 34 surrounding the planar light source 32, the test pattern 31, and the optical glass 33, connecting them into a whole. This facilitates the simultaneous adjustment of the planar light source 32 and the test pattern 31 by the leveling component 37. The leveling component 37 adjusts the levelness of the mounting frame 34 so that both the test pattern 31 and the planar light source 32 are in a horizontal plane, thereby further meeting the positional requirements of the planar light source 32 and the test pattern 31 during alignment operations. Therefore, the pattern assembly 3 provided in this embodiment can effectively ensure the accuracy of alignment.

[0098] Specifically, such as Figure 9 and Figure 10 As shown, the leveling assembly 37 includes multiple lifting assemblies 371. At least one lifting assembly 371 is connected to the bottom of each opposite end of the mounting frame 34, and the bottom ends of the multiple lifting assemblies 371 are all disposed on the carrier plate 36. Each lifting assembly 371 can adjust the angle of the mounting frame 34 by lifting its corresponding part, thereby adjusting the planar light source 32 and the test chart 31 to a horizontal plane.

[0099] More specifically, such as Figure 10 and Figure 12As shown, the lifting assembly 371 includes an adjusting bolt 3711 and a locking threaded sleeve 3712. The adjusting bolt 3711 is threadedly connected to the carrier plate 36, with its head located below the carrier plate 36 and its tail supported on the bottom of the mounting frame 34. The locking threaded sleeve 3712 is threaded onto the adjusting bolt 3711 and abuts against the bottom of the carrier plate 36. The adjusting bolt 3711 can be moved up and down relative to the carrier plate 36 by screwing, thereby abutting against the mounting frame 34 to achieve lifting. After the position is properly adjusted, the locking threaded sleeve 3712 is locked to the bottom of the carrier plate 36, providing stronger support for the drawing assembly 3.

[0100] More specifically, the lifting assembly 371 also includes a fixing bolt 3713 and a base plate 3714. The base plate 3714 is fixedly connected to the bottom of the mounting frame 34. The fixing bolt 3713 is movably inserted through the adjusting bolt 3711. The head of the fixing bolt 3713 is located outside the adjusting bolt 3711 and abuts against the head of the adjusting bolt 3711. The tail of the fixing bolt 3713 is threaded and locked inside the base plate 3714. The arrangement of the fixing bolt 3713 and the base plate 3714 further improves the stability of the support for the drawing assembly 3.

[0101] In this embodiment, two lifting components 371 are provided at the bottom of each of the two first frame plates 341, and the two lifting components 371 on the same first frame plate 341 are respectively provided at both ends of the first frame plate 341.

[0102] Specifically, such as Figure 1 As shown, the camera alignment device also includes a lifting assembly, which includes a lead screw 51, a nut 52, and a drive assembly 53. The lead screw 51 is rotatably connected to the base frame 1 around its own axis and extends vertically. The nut 52 is threaded onto the lead screw 51 and connected to the drawing card assembly 3. The drawing card assembly 3 is slidably connected to the base frame 1 vertically. The drive assembly 53 is connected to the base frame 1, and one end of the lead screw 51 is connected to the output end of the drive assembly 53. The drive assembly 53 is used to drive the lead screw 51 to rotate, thereby moving the drawing card assembly 3 up and down via the nut 52. The working part is located above the drawing card assembly 3. The height of the drawing card assembly 3 determines the size of the space below it. Therefore, the lifting assembly allows the camera alignment device to be used for different sizes of products 10 to be assembled. In this embodiment, the nut 52 is connected to the carrier plate 36 of the drawing card assembly 3, realizing the overall lifting of the drawing card assembly 3.

[0103] In this embodiment, the two ends of the lead screw 51 are rotatably connected to the bearing seat 11 and the top plate 13, respectively, and pass through the carrier plate 36. The nut 52 is fixedly installed inside the carrier plate 36. The lead screw 51 not only drives the drawing assembly 3 to move up and down, but also provides support for the top plate 13.

[0104] More specifically, the drive assembly 53 includes a drive member 531, a drive pulley 532, a timing belt 533, and a driven pulley 534. The drive member 531 is mounted on the base frame 1; the drive pulley 532 is mounted on the base frame 1 and connected to the output end of the drive member 531, which drives the drive pulley 532 to rotate; one end of the timing belt 533 is wound around the drive pulley 532; the driven pulley 534 is mounted on the base frame 1 and coaxially connected to the lead screw 51, with the other end of the timing belt 533 wound around the driven pulley 534. The cooperation of the drive member 531, drive pulley 532, timing belt 533, and driven pulley 534 enables the rotational drive of the lead screw 51.

[0105] In this embodiment, two lead screws 51 and two nuts 52 are provided. The two lead screws 51 are respectively connected to the middle of opposite sides of the two top plates 13. Correspondingly, each lead screw 51 has a driven wheel 534 at its top end. The two driven wheels 534 are driven by a driving member 531, a driving wheel 532, and a synchronous belt 533. The driving member 531 is a motor.

[0106] like Figure 1 As shown, the drive component 531, drive wheel 532, timing belt 533 and driven wheel 534 are all mounted on the top plate 13, which is securely fixed and not easy to fall off the base frame 1, and occupies little space.

[0107] Specifically, each support column 12 is fixedly provided with a limiting member 14, which is used to limit the lowest position of the diagram assembly 3 to prevent it from colliding with the parallel light assembly 2 and the relay mirror assembly 4 due to excessive downward adjustment.

[0108] More specifically, the limiting member 14 includes two opposing semicircular rings that fit onto the support column 12. This arrangement facilitates the installation and removal of the limiting member 14. Preferably, an elastic protective layer formed by rubber coating is provided on the top surface of the semicircular rings.
