Description

Verification method for panoramic lens focusing station

This case relates to a method for verifying lens focusing, and more particularly to a method for verifying a lens focusing station capable of focusing panoramic lenses.

During lens assembly, a focusing station performs a pre-focus test on the temporarily assembled semi-finished lens to confirm the correct focal length between the lens and the printed circuit board (PCB). Then, an active alignment (AA) station completes the bonding with the PCB components. Finally, the assembled lens undergoes a re-focus test at another focusing station to ensure the lens maintains sharpness before and after processing. However, during lens assembly, it's easy to accidentally touch a lens before the adhesive has fully cured, causing a difference in focal length between before and after bonding.

To address the aforementioned problems, as shown in the first figure, a lens focusing station 100 is designed to reduce accidental lens activation. The lens focusing station 100 includes: a base 10, a lens actuator assembly 20, a lens mount 30, an image capturing unit 40, a focuser 50, a planar light source device 65, and a control unit (not shown). The planar light source device 65 is fixed above the base 10, illuminating the lens mount 30 from above. Through the controllable lens actuator assembly 20, focuser 50, and planar light source device 65, the lens focusing station 100 can perform focusing tests on general lenses. However, panoramic lenses are relatively large and have a wide field of view, so the aforementioned lens focusing station 100 is not suitable for focusing tests on panoramic lenses.

Please refer to Figure 2. This invention discloses a verification method for a panoramic lens focusing station. The panoramic lens focusing station 200 is configured to perform focusing tests on a panoramic lens 201 and includes: a base 10, a lens actuator assembly 20 fixed on the base 10, a lens mounting base 30 disposed on the lens actuator assembly 20, an image capturing unit 40 disposed on the lens mounting base 30, a focusing device 50 fixed on the base 10, four light source devices 60 respectively fixed at the four corners of the base 10, a first imaging device 70 fixed above the base 10, a second imaging device 80 disposed on the lens actuator assembly 20, and a control unit 90.

In this embodiment, the lens actuator assembly 20 includes a first linear slide rail 21 with its track parallel to the upper surface of the base 10, a second linear slide rail 22 connected to a slider of the first linear slide rail 21, a third linear slide rail 23 connected to a slider of the second linear slide rail 22, and a fourth linear slide rail 24 connected to a slider of the third linear slide rail 23. The track of the first linear slide rail 21 is perpendicular to the track of the second linear slide rail 22, and the track of the first linear slide rail 21 is configured to run in a forward-backward direction, while the track of the second linear slide rail 22 is configured to run in a left-right direction. The track of the third linear slide rail 23 is perpendicular to the track of the fourth linear slide rail 24, and the track of the third linear slide rail 23 is parallel to the track of the first linear slide rail 21. The first linear slide rail 21, the second linear slide rail 22, the third linear slide rail 23, and the fourth linear slide rail 24 are all driven by servo motors, thereby enabling the control unit 90 to move the lens mount 30 to a designated position by controlling the lens actuator assembly 20.

Both the lens mount 30 and the second camera device 80 are mounted on the lens actuator assembly 20 to move to a designated position under the drive of the lens actuator assembly 20, and the lens mount 30 is used to fix the panoramic lens 201. In this embodiment, when the slider of the first linear slide rail 21 moves, the lens mount 30 and the second imaging device 80 move forward or backward. When the slider of the second linear slide rail 22 moves, the lens mount 30 and the second imaging device 80 move left or right. When the slider of the third linear slide rail 23 moves, the lens mount 30 moves slightly forward or backward. When the slider of the fourth linear slide rail 24 moves, the lens mount 30 moves slightly left or right. The image capturing unit 40 is disposed on the lens mount 30 and located on the optical axis of the panoramic lens 201 to capture images through the panoramic lens 201.

The panoramic lens 201 is equipped with a focus adjustment ring, and the focus adjuster 50 is equipped with a clamp that engages with the focus adjustment ring. The focus adjuster 50 is located on the right side of the track of the first linear slide rail 21 and includes a fifth linear slide rail 51 and a first turntable 52 with a slider disposed on the fifth linear slide rail 51. The track of the fifth linear slide rail 51 is configured vertically, parallel to the rotation axis of the first turntable 52, and perpendicular to the track of the first linear slide rail 21.

The slider of the sliding rail 51 moves the clasp away from or near the lens holder 30, and the clasp is disposed on the surface of the first turntable 52. The rotation of the surface of the first turntable 52 causes the clasp to rotate in a clockwise or counterclockwise direction, thereby adjusting the relative distance and relative angle between the clasp and the focus adjustment ring.

Referring again to the second figure, the control unit 90 is electrically connected to the lens actuator assembly 20 and the focuser 50 to control the operation of each servo motor in the lens actuator assembly 20 and the focuser 50. The control unit 90 is also electrically connected to the first camera device 70 and the second camera device 80 to receive images captured by the first camera device 70 and the second camera device 80. The control unit 90 is also electrically connected to the light source device 60 to control the activation of the light source device 60. Furthermore, the control unit 90 is electrically connected to the image capture unit 40 to receive images captured by the image capture unit 40 and determine whether the focusing test of the panoramic lens 201 is successful.

Please refer to Figures 2 and 3. The panoramic lens focusing station 200 is located before and after the active calibration station that bonds the panoramic lens 201 to the printed circuit board assembly. The verification method of the panoramic lens focusing station 200 includes the following steps:

S10: The control unit 90 controls the lens actuator assembly 20 and the focuser 50 according to a preset data to correct the position of the panoramic lens 201 and the position of the clasp, so as to move the focus adjustment ring to the position of the clasp and make the clasp engage the focus adjustment ring.

S10’: When the control unit 90 determines that the focus adjustment ring cannot properly engage the caliper, it executes step S11; when the control unit 90 determines that the focus adjustment ring can properly engage the caliper, it executes step S12.

S11: The control unit 90 generates a test result including test failure and controls the lens actuator assembly 20 according to the preset data to return the lens actuator assembly 20 to the origin, which is the initial position of the lens actuator assembly 20.

S12: The control unit 90 controls the focuser 50 to adjust the focal length of the panoramic lens 201 according to a preset data and performs a focus test.

S12’: When the control unit 90 determines that the panoramic lens 201 has passed the focusing test, step S13 is executed; when the control unit 90 determines that the panoramic lens 201 has failed the focusing test, step S11 is executed.

S13: The control unit 90 generates a test result indicating that the test has passed, and controls the lens actuator assembly 20 according to the preset data to return the lens actuator assembly 20 to its origin. In this embodiment, the control unit 90 is provided with a user interface to display the test result.

Please refer to Figures 4 through 4B for a detailed description of steps S10 and S10'.

S20’: The panoramic lens 201 is mounted on the lens mount 30 by the operator. In this embodiment, in the panoramic lens focusing station 200 preceding the active calibration station, the lens mount 30 is provided with a printed circuit board assembly electrically connected to the image capturing unit 40. The operator fixes the panoramic lens 201 to the lens mount 30 and connects the printed circuit board assembly to the panoramic lens 201, so that the panoramic lens 201 is electrically connected to the image capturing unit 40 through the printed circuit board assembly. In the panoramic lens focusing station 200 following the active calibration station, the operator fixes the panoramic lens 201, which is already bonded to the printed circuit board assembly, onto the lens mount 30.

S20: The control unit 90 controls the lens actuator assembly 20 according to a preset data, so that the panoramic lens 201 moves forward from the initial position to below the first camera device 70 and is aligned with the first camera device 70. The control unit 90 controls the first camera device 70 to take a picture of the front of the panoramic lens 201 and send back a focus adjustment ring image 71. Then, step S21 is executed.

S21: The control unit 90 identifies whether the focus adjustment ring image 71 has a minimum circumscribed circle and a minimum circumscribed rectangle according to the preset data. When the focus adjustment ring image 71 has the circumscribed circle and the minimum circumscribed rectangle, step S22 is executed. When the focus adjustment ring image 71 does not have the circumscribed circle and the minimum circumscribed rectangle, step S11 is executed.

S22: The control unit 90 calculates the angle of the circumscribed rectangle from the horizontal axis to obtain a focus adjustment ring angle 72, and then executes step S23. In this embodiment, the circumscribed rectangle is close to a square. When the control unit 90 calculates the angle of the circumscribed rectangle from the horizontal axis, it rotates the horizontal axis counterclockwise with the upper left corner of the focus adjustment ring image 71 as the center, and passes through the extension line of the side of the circumscribed rectangle. The focus adjustment ring angle 72 is the angle between the horizontal axis and the first extension line encountered when the horizontal axis rotates.

S23: The control unit 90 controls the lens actuator assembly 20 according to the preset data, so that the second camera device 80 moves forward to below the caliper and aligns with the caliper, and resets the calibration count to zero, and then executes step S24.

S24: The control unit 90 controls the second camera device 80 to capture images of the calipers and transmit a caliper image 81 back.

S24’: The control unit 90 identifies whether the clamp image 81 has the circumscribed circle and the circumscribed rectangle according to the preset data. When the clamp image 81 has the circumscribed circle and the circumscribed rectangle, step S25 is executed. When the clamp image 81 does not have the circumscribed circle and the circumscribed rectangle, step S11 is executed.

S25: The control unit 90 calculates the angle of the circumscribed rectangle deviating from the horizontal axis to obtain a clamp angle 82, and then executes step S26. In this embodiment, the calculation method for obtaining the clamp angle 82 is similar to that for obtaining the focus adjustment ring angle 72. The control unit 90 rotates the horizontal axis counterclockwise with the upper left corner of the clamp image 81 as the center. The clamp angle 82 is the angle between the horizontal axis and the first extension line of the circumscribed rectangle side encountered when the horizontal axis rotates.

S26: The control unit 90 calculates the difference between the focus adjustment ring angle 72 and the caliper angle 82, and then executes step S27.

S27: The control unit 90 compares whether the number of corrections is less than a maximum correction number. If the number of corrections is less than the maximum correction number, step S28 is executed; if the number of corrections is equal to the maximum correction number, step S11 is executed. In this embodiment, the maximum correction number, a preset standard value, and a maximum focusing number are all preset values and stored in a storage medium accessible by the control unit 90.

S28: The control unit 90 compares whether the difference is less than the preset standard value. If the difference is less than the preset standard value, step S12 is executed; if the difference exceeds the preset standard value, step S29 is executed. In practice, a difference below the preset standard value indicates that the focus adjustment ring and the clamp are correctly aligned, and the panoramic lens 201 and the focuser 50 can be correctly aligned. A difference exceeding the preset standard value indicates that the focus adjustment ring and the clamp are not correctly aligned, and the panoramic lens 201 and the focuser 50 cannot be correctly aligned.

S29: The control unit 90 controls the focusing device 50 according to the preset data, causing the caliper to rotate in a specified direction by a specified angle, and increments the correction count by one, then executes step S24. In this embodiment, the preset data further includes the servo motor parameters of the focusing device 50, for example: the angle value of the caliper rotation corresponding to the servo motor rotating one scale. The control unit 90 converts the difference into the scale value that the servo motor should rotate to control the servo motor, causing the focusing device 50 to rotate the caliper, thereby reducing the difference.

Please refer to Figures 5 through 5A. Steps S12 and S12' are described in detail below:

S30: The control unit 90 controls the focuser 50 according to the preset data, so that the clamp moves down until it engages with the focus adjustment ring, and the focus count is reset to zero, and then step S31 is executed.

S31: The control unit 90 turns on the light source device 60, and the panoramic lens 201 and the image capture unit 40 capture a test image 61. The image capture unit 40 captures an image 203 to be evaluated and transmits it to the control unit 90. Then, step S32 is executed. In this embodiment, the light tube of the light source device 60 is equipped with the test image 61.

S32: The control unit 90 compares whether the number of focusing times is less than the upper limit of focusing times. If the number of focusing times is less than the upper limit of focusing times, step S33 is executed. If the number of focusing times is equal to the upper limit of focusing times, step S11 is executed.

S33: The control unit 90 analyzes the image 203 to be evaluated according to the preset data to obtain a score.

S33': The control unit 90 compares whether the score is within a preset score range. When the score is within the preset score range, step S13 is executed; when the score exceeds the preset score range, step S34 is executed. In this embodiment, the preset score range is 0.4 to 0.6.

S34: The control unit 90 controls the focuser 50 according to the preset data, so that the caliper rotates slightly in the specified direction by a specified angle, and the focusing number is incremented by one, and then the step S31 is executed.

The control unit 90 may be a desktop computer, a laptop computer, or any component or device suitable for displaying an interface and capable of receiving user input and simultaneously having data access, data calculation, data storage, or similar functions, but is not limited thereto.

In summary, compared with the prior art, the verification method of the panoramic lens focusing station 200 of the present invention, by adjusting the focus of the panoramic lens 201 before and after bonding it to the printed circuit board, can avoid the focusing inaccuracy of the panoramic lens 201 after processing, improve the focus accuracy of the panoramic lens 201, and thus improve the quality of the panoramic lens product.
