Description

Technical Field

[0001] This invention relates to the field of lens inspection and installation technology, and in particular to a miniature lens focusing and installation device and method. Background Technology

[0002] Currently, traditional lens testing and installation techniques require manual operation. Specifically, the lens is placed on the PCB board manually, the lens is rotated manually to adjust the distance between the lens and the lens chip, the lens is moved manually to align the lens with the center of the lens chip on the PCB board, and then adhesive is applied and cured manually.

[0003] The aforementioned lens testing and installation process is quite complex, resulting in low lens assembly efficiency. Manual operation is prone to errors, leading to product scrapping and hindering large-scale lens assembly. Furthermore, the assembly process requires highly skilled installers, increasing labor costs. Summary of the Invention

[0004] The purpose of this invention is to address the technical problems of existing lens inspection and installation technologies in the background art, namely, "the assembly process is relatively complex, resulting in low lens assembly efficiency, and manual operation is prone to errors, leading to product scrapping, which is not conducive to large-scale lens assembly, and the above assembly process has high technical requirements for the installation personnel, increasing labor costs." In this invention, a miniature lens focusing and installation device and method are proposed.

[0005] The present invention provides a miniature lens focusing and mounting device, comprising an operating platform, on which a first positioning mechanism, a second positioning mechanism, and a mounting mechanism are provided. The first positioning mechanism and the second positioning mechanism are respectively used to connect to a PCB board and a lens. The mounting mechanism includes a driving device and an assembly device. The driving device is connected to the assembly device and is used to drive the assembly device to move between the first positioning mechanism and the second positioning mechanism. The assembly device is used to assemble the lens onto the PCB board.

[0006] Furthermore, the assembly device includes a focusing gear, a rotary cylinder, and a lifting cylinder. The focusing gear has an insertion port below it for connecting to the lens. The rotary cylinder and the lifting cylinder are respectively connected to the focusing gear. The rotary cylinder is used to drive the focusing gear to rotate, and the lifting cylinder is used to drive the focusing gear to move up and down.

[0007] The assembly device also includes a first clamping part, a second clamping part, and a first clamping cylinder. The first clamping part and the second clamping part are disposed on both sides of the insertion port. The first clamping cylinder is connected to the first clamping part and the second clamping part and is used to drive the first clamping part and the second clamping part to move toward the insertion port.

[0008] Furthermore, it also includes a light-emitting component, and a support frame is provided on the operating platform. The light-emitting component is located above the first positioning mechanism and is movably connected to the support frame through the attitude adjustment platform. The light-emitting component is equipped with a laser pointer and a detection light source, and the detection light source is located around the laser pointer.

[0009] Furthermore, the operating platform is also equipped with a visual inspection mechanism, which is used to monitor the relative position of the laser pointer and the PCB board in order to control the posture adjustment platform to drive the light-emitting components to move so that the laser pointer and the PCB board are perpendicular to each other.

[0010] Furthermore, the first positioning mechanism is provided with a mounting groove at the top, a positioning pin is provided in the mounting groove, and a positioning hole is provided on the PCB board. The positioning pin passes through the positioning hole to realize the installation of the PCB board in the mounting groove.

[0011] The first positioning mechanism also includes a clamping device, which forms a clamping part at the top. The clamping part is located above the mounting groove and can move up and down relative to the mounting groove. When the PCB board is connected to the mounting groove, the clamping part moves down until it contacts the PCB board to press the PCB board into the mounting groove.

[0012] The second positioning mechanism is provided with an insertion slot at the top for connecting with the lens. The insertion slot is provided with a third clamping part and a fourth clamping part on both sides, and the third clamping part and the fourth clamping part are connected to the second clamping cylinder.

[0013] The second positioning mechanism also includes a laser sensor, which is positioned above the insertion slot;

[0014] The focusing gear is also equipped with a curing lamp, which is used to cure the adhesive between the lens and the PCB board to achieve a fixed connection between the lens and the PCB board.

[0015] Furthermore, the present invention also provides a focusing and mounting method for a lens applied to the device of the present invention, the focusing and mounting method for the lens comprising the following steps:

[0022] Place the PCB board in the mounting slot;

[0023] A visual inspection mechanism is used to determine whether the laser pointer is perpendicular to the PCB board.

[0024] If the laser pointer is not perpendicular to the PCB board, the light-emitting component is moved by the posture adjustment platform to adjust the laser pointer so that it is perpendicular to the PCB board.

[0025] Furthermore, the step of "placing the lens on the second positioning mechanism and moving the assembly device to the lens for preliminary focusing" includes:

[0026] Place the lens into the mounting slot;

[0027] The height of the lens section is checked using a laser sensor to determine if it meets the required standards.

[0028] If it fails to meet the requirements, the third and fourth clamping parts will clamp the lens tightly.

[0029] Move the focus gear downwards so that the lens is inserted into the mounting port.

[0030] Rotate the focusing gear to adjust the height of the lens section, thereby achieving initial focusing of the lens.

[0031] Furthermore, the step of "precision focusing of the lens using the assembly device" includes:

[0032] The lens captures real-time image information of the laser pointer and the detection light source.

[0033] The collected image information is uploaded to the detection system via the PCB board;

[0034] The detection system analyzes whether the lens's focal length is up to standard by detecting image information;

[0035] If it is not up to standard, rotate the focusing gear to fine-tune the lens's focal length.

[0036] Furthermore, the step of "fixing the lens onto the PCB board using the assembly device" includes:

[0037] A curing lamp is used to cure the adhesive between the lens and the PCB board, thereby achieving a fixed connection between the lens and the PCB board.

[0038] Compared with the prior art, the present invention has the following beneficial technical effects: Because the lens inspection and installation device of the present invention is provided with a first positioning mechanism, a second positioning mechanism, and an installation mechanism, specifically the installation mechanism includes a driving device and an assembly device, through the above structural arrangement, when installing the lens, the driving device can be activated to drive the assembly device to move to the second positioning mechanism, the assembly device "grabs" the lens on the second positioning mechanism, and then the assembly device moves to the first positioning mechanism to connect the lens to the PCB board. Through the above structural arrangement, the device of the present invention can realize the automated installation of the lens, which greatly improves the installation efficiency and accuracy of the lens and reduces labor costs compared with the traditional manual installation method.

[0052] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0053] Example 1

[0054] like Figures 1-5 As shown, the present invention proposes a miniature lens focusing and mounting device, including an operating platform 1. The operating platform 1 is provided with a first positioning mechanism 11, a second positioning mechanism 12 and a mounting mechanism 13. The first positioning mechanism 11 and the second positioning mechanism 12 are respectively used to connect to a PCB board and a lens. The mounting mechanism 13 includes a driving device 131 and an assembly device 132. The driving device 131 is connected to the assembly device 132 and is used to drive the assembly device 132 to move between the first positioning mechanism 11 and the second positioning mechanism 12. The assembly device 132 is used to mount the lens onto the PCB board.

[0055] Specifically, in this embodiment, the driving device 131 includes an "X-axis driving unit" and a "Y-axis driving unit". The "X-axis driving unit" is used to control the movement of the assembly device 132 in the "X-axis" direction, and the "Y-axis driving unit" is used to control the movement of the assembly device 132 in the "Y-axis" direction. With the above structural arrangement, the assembly device 132 can move relative to the operating platform 1 at various positions in the horizontal direction.

[0056] It is understood that when lens installation is required, other automated equipment, such as a robotic arm, can be used to place the PCB board and lens on the first positioning mechanism 11 and the second positioning mechanism 12 respectively. The drive device 131 is then activated to move the assembly device 132 to the second positioning mechanism 12. The assembly device 132 "grabs" the lens on the second positioning mechanism 12, and then moves the assembly device 132 to the first positioning mechanism 11 to connect the lens to the PCB board. Through the above structural setup, the device of the present invention can realize automated lens installation. Compared with the traditional manual installation method, it greatly improves the installation efficiency and accuracy of the lens and reduces labor costs.

[0057] Specifically, in this embodiment, the first positioning mechanism 11 is provided with a mounting groove 111 at the top, a positioning pin 112 is provided in the mounting groove 111, a positioning hole is provided on the PCB board, and the positioning pin 112 passes through the positioning hole to realize the installation of the PCB board in the mounting groove 111. Furthermore, in this embodiment, a probe is provided below the mounting groove 111. The probe is used to electrically connect with the PCB board to supply power to the PCB board.

[0058] Furthermore, the first positioning mechanism 11 also includes a pressing device 113. The pressing device 113 forms a pressing part 1131 at the top. The pressing part 1131 is disposed above the mounting groove 111 and can move up and down relative to the mounting groove 111. Specifically, the pressing part 1131 can move up and down relative to the mounting groove 111 by means of a cylinder. When the PCB board is connected to the mounting groove 111, the pressing part 1131 moves downward until it contacts the PCB board to press the PCB board into the mounting groove 111.

[0059] With the above structural setup, the PCB board will be fixed in the mounting groove 111 by the positioning pin 112 and the clamping part 1131, so as to achieve a fixed connection between the PCB board and the first positioning mechanism 11.

[0060] Furthermore, the second positioning mechanism 12 of this embodiment is provided with an insertion slot 121 at the top, which is used to connect with the lens. The insertion slot 121 is provided with a third clamping part 23 and a fourth clamping part 24 on both sides. The third clamping part 23 and the fourth clamping part 24 are connected to the second clamping cylinder 202. With the above structure, the lens can be placed in the insertion slot 121. The third clamping part 23 and the fourth clamping part 24 can move toward the insertion slot 121 through the second clamping cylinder 202 until they are clamped to the lens, so as to realize the fixed connection between the lens and the second positioning mechanism 12.

[0061] Furthermore, the device in this embodiment also includes a light-emitting component 3, which is disposed above the first positioning mechanism 11. The light-emitting component 3 is provided with a laser pen 31 and a detection light source 32. The detection light source 32 is disposed around the laser pen 31. In one embodiment, the detection light source 32 includes 8 light sources, which are evenly distributed around the laser pen.

[0062] It is understood that the light-emitting component 3 in this embodiment is mainly used for lens focusing. Specifically, when the lens is placed on the PCB board, since the light-emitting component 3 is located above the first positioning mechanism 11, the lens can collect the light spots of the laser pointer 31 and the light spots of the detection light source 32 above to form image information. The image information can be transmitted to the detection system, such as a computer host, through the PCB board. The detection system can analyze the light spot imaging diagram in the image information to determine whether the focal length of the lens is qualified. If it is not qualified, the lens needs to be focused.

[0063] It should be noted that in order to ensure the accuracy of focusing the lens on the PCB board, the laser pointer 31 needs to be set perpendicular to the PCB board. In this embodiment, the operating platform 1 is also provided with a support frame 14. The light-emitting component 3 is movably connected to the support frame 14 through the posture adjustment platform 15. Furthermore, the operating platform 1 is also provided with a vision detection mechanism 16. The vision detection mechanism 16 is used to monitor the relative position of the laser pointer 31 and the PCB board in order to control the posture adjustment platform 15 to drive the light-emitting component 3 to move so that the laser pointer 31 and the PCB board are perpendicular to each other.

[0064] As one embodiment of this invention, a light-transmitting part 311 is provided below the laser pointer 31. The laser passes through the light-transmitting part 311 to form a light-transmitting point and irradiates the chip on the PCB board for connection with the lens. The chip reflects the laser, and the emitted laser is directed toward the light-transmitting part 311, forming a reflection point on the light-transmitting part 311.

[0065] In this embodiment, the visual inspection mechanism 16 can determine whether the laser pointer is perpendicular to the PCB board by observing whether the light-transmitting point and the reflection point coincide. Specifically, if the light-transmitting point and the reflection point coincide, it means that the laser pointer 31 is perpendicular to the PCB board. If they do not coincide, it means that the laser pointer 31 is not perpendicular to the PCB board. At this time, the visual inspection mechanism 16 can control the posture adjustment platform 15 to move the light-emitting component 3 according to the observed relative position of the light-transmitting point and the reflection point until the light-transmitting point and the reflection point coincide, so that the laser pointer 31 is perpendicular to the PCB board. Preferably, the operation platform 1 is also provided with a supplementary light device 17 for supplementary light to the light-transmitting part 311, so as to facilitate the observation of the light-transmitting point and the reflection point by the visual inspection mechanism 16.

[0066] Furthermore, in this embodiment, the assembly device 132 includes a focusing gear 1321, a rotary cylinder 1322, and a lifting cylinder 1323. An insertion port 1324 is provided below the focusing gear 1321 for connecting to the lens. Specifically, in this embodiment, the insertion port 1324 passes through the focusing gear 1321 from top to bottom so that the lens can observe the light-emitting component 3 through the insertion port 1324.

[0067] Furthermore, the rotary cylinder 1322 and the lifting cylinder 1323 are respectively connected to the focusing gear 1321. The rotary cylinder 1322 is used to drive the focusing gear 1321 to rotate, and the lifting cylinder 1323 is used to drive the focusing gear 1321 to move up and down relative to the first positioning mechanism 11.

[0068] Furthermore, the assembly device 132 also includes a first clamping part 21, a second clamping part 22, and a first clamping cylinder 201. The first clamping part 21 and the second clamping part 22 are disposed on both sides of the insertion port 1324. The first clamping cylinder 201 is connected to the first clamping part 21 and the second clamping part 22 and is used to drive the first clamping part 21 and the second clamping part 22 to move toward the insertion port 1324 to "grab" the lens.

[0069] With the above structural configuration, when installing the lens to the PCB board, the movable assembly device 132 can be moved to the second positioning mechanism 12 to position the insertion port 1324 directly above the lens. The focusing gear 1321 is moved downward to connect the lens to the insertion port 1324. The first clamping cylinder 201 is activated to clamp the lens with the first clamping part 21 and the second clamping part 22. Then, the assembly device 132 is moved to the first positioning mechanism 11 to place the lens on the PCB board.

[0070] It should be noted that the lens in this embodiment includes a lens part and a lens frame part. The lens part and the lens frame part are connected by a threaded screw. Rotating the lens part can move the lens part up or down relative to the lens frame part to adjust the lens focal length.

[0071] In this embodiment, the focusing gear 1321 can pre-adjust the focal length of the lens at the second positioning mechanism 12. To achieve the above-mentioned technical effect, specifically, the second positioning mechanism 12 also includes a laser sensor 122. The laser sensor 122 is disposed above the insertion slot 121. The laser sensor 122 can be used to detect whether the height of the lens part relative to the lens frame part meets the standard. If it does not meet the standard, when the assembly device 132 moves to the second positioning mechanism 12, the focusing gear 1321 can be rotated to drive the lens part to rotate relative to the lens frame part, thereby achieving the desired effect. For the initial focusing of the lens, after the assembly device 132 moves to the first positioning mechanism 11, the lens can form a light spot image by observing the light source of the laser pointer 31 and the detection light source 32 set above it. The light spot image is then uploaded to the detection system, such as the host, via the PCB board. The host can analyze whether the light spots in the light spot image are qualified to determine whether the lens focal length is accurate. If it is not qualified, the host can control the focusing gear 1321 to rotate the lens until the light spots in the light spot image reach the qualified standard, thereby achieving precise focusing of the lens focal length.

[0072] Furthermore, a curing lamp 1325 is also provided below the focusing gear 1321. After the focal length of the lens is adjusted, the curing lamp 1325 can be activated to cure the adhesive between the lens and the PCB board, so as to achieve a fixed connection between the lens and the PCB board.

[0073] Example 2

[0074] like Figures 6-10 As shown, this embodiment proposes a focusing and mounting method for a lens applied to the lens inspection and mounting device in Embodiment 1. Specifically, the method of this embodiment includes the following steps:

[0075] S1: Place the PCB board in the first positioning mechanism 11;

[0076] S2: Place the lens on the second positioning mechanism 12 and move the assembly device 132 to the lens to perform preliminary focusing on the lens;

[0077] S3: The lens is placed on the PCB board using the assembly device 132;

[0078] S4: Use assembly device 132 to perform precision focusing on the lens;

[0079] S5: Fix the lens on the PCB board.

[0080] Through the above steps, the lens focusing and installation method of the present invention can replace the traditional manual lens installation and manual focusing operations. Specifically, by setting up the assembly device 132 to realize the lens installation and focusing operations, the lens installation efficiency and focusing accuracy are improved.

[0081] It is understood that in this embodiment, in order to improve the speed and accuracy of focusing in step S4, the focal length of the lens can be coarsely adjusted in step S2 by the assembly device 132 on the second positioning mechanism 12, and then finely adjusted on the PCB board after the coarse adjustment. After the focal length adjustment is completed, the lens can be fixed on the PCB board.

[0082] Furthermore, in this embodiment, the steps of "placing the PCB board in the first positioning mechanism 11" and "placing the lens in the second positioning mechanism 12" in steps S1 and S2 can be automatically implemented by a robotic arm.

[0083] Furthermore, to ensure the focusing accuracy of the lens in step S4, step S1 also includes the following steps:

[0084] S11: Place the PCB board in the mounting slot 111;

[0085] S12: The visual inspection mechanism 16 determines whether the laser pointer 31 is perpendicular to the PCB board;

[0086] S13: If the laser pointer 31 is not perpendicular to the PCB board, the light-emitting component 3 is moved by the posture adjustment platform 15 to adjust the laser pointer 31 to be perpendicular to the PCB board.

[0087] In step S12, the visual inspection mechanism 16 can determine whether the laser pointer 31 is perpendicular to the PCB board by observing whether the light-transmitting point and the reflection point coincide. Specifically, if the light-transmitting point and the reflection point coincide, it means that the laser pointer 31 is perpendicular to the PCB board; if they do not coincide, it means that the laser pointer 31 is not perpendicular to the PCB board. In step S13, the posture adjustment platform 15 can move the light-emitting component 3 according to the relative position of the light-transmitting point and the reflection point observed by the visual inspection mechanism 16, so that the laser pointer 31 is perpendicular to the PCB board. Through the above steps, the laser pointer 31 can be kept perpendicular to the PCB board, ensuring that after the lens is connected to the PCB board, the laser pointer and the detection light source 32 illuminate the lens perpendicularly, thus improving the subsequent focusing accuracy of the lens.

[0088] Furthermore, step S2 also includes the following steps:

[0089] S21: Place the lens into the insertion slot 121;

[0090] S22: The height of the lens section is checked using laser sensor 122 to determine if it is within acceptable limits;

[0091] S23: If it fails, the third clamping part 23 and the fourth clamping part 24 will clamp the lens tightly;

[0092] S24: Move the downward focusing gear 1321 to insert the lens into the mounting port 1324.

[0093] S25: Rotate the focusing gear 1321 to achieve initial focusing of the lens.

[0094] The following will provide a detailed explanation of lens focusing in conjunction with the above steps. It can be understood that, since the lens in this embodiment includes a lens part and a lens frame part, and the lens part and the lens frame part are connected by a threaded screw, rotating the lens part can move the lens part up or down relative to the lens frame part to adjust the lens focal length.

[0095] Through the above steps S21-S25, the focusing gear 1321 can pre-adjust the focal length of the lens at the second positioning mechanism 12. Specifically, the lens is first placed in the insertion slot 121, and the lens height is checked by the laser sensor 122. If it is not qualified, the lens needs to be pre-focused. Before the pre-focusing, the third clamping part 23 and the fourth clamping part 24 clamp the lens frame part, and the focusing gear 1321 is moved downward so that the lens part is inserted into the insertion port 1324. The focusing gear 1321 is rotated to drive the lens part to rotate relative to the lens frame part until the lens part is rotated to a suitable height to achieve the pre-focusing of the lens.

[0096] Furthermore, step S4 also includes the following steps:

[0097] S41: Real-time acquisition of image information from laser pointer 31 and detection light source 32 via lens;

[0098] S42: Upload the collected image information to the detection system via the PCB board;

[0099] S43: The detection system analyzes whether the lens focal length is qualified by detecting image information;

[0100] S44: If it fails, rotate the focusing gear 1321 to fine-tune the focal length of the lens.

[0101] Through the above steps, once the lens is connected to the PCB board, the lens focal length can be finely adjusted. Specifically, the focusing principle is that the lens can form a light spot image by observing the light source set above it, which includes a laser pointer 31 and a detection light source 32. The light spot image is then uploaded to the detection system, such as a host computer, via the PCB board. The host computer can analyze whether the light spots in the light spot image are qualified to determine whether the lens focal length is accurate. If it is not qualified, the host computer can control the focusing gear 1321 to rotate the lens until the light spots in the light spot image reach the qualified standard, thereby achieving precise focusing of the lens focal length.

[0102] Furthermore, step S5 also includes the following steps:

[0103] S51: Use a curing lamp 1325 to cure the adhesive between the lens and the PCB board, thereby achieving a fixed connection between the lens and the PCB board.

[0104] The above descriptions provide one or more embodiments in conjunction with specific details, but do not imply that the specific implementation of the present invention is limited to these descriptions. Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
