Furthermore, well-known steps or elements are not described in the details to avoid creating unnecessary limitations on this utility model.

[0023] Figure 1This is a schematic diagram of a calibration device 100 according to an embodiment of the present invention; Figure 2 yes Figure 1 Exploded view of calibration device 100.

[0024] Reference Figure 1 and Figure 2 The calibration device 100 can be used to adjust the axial direction of any two components of the product, so that the axial directions of the two components in the Z-axis direction are substantially coincident. The calibration device 100 includes at least a fixture 10, a translation module 20, a drive module 30, a gripper 40, and a connecting plate 50. The fixture 10 can be disposed in the XY plane, the translation module 20 and the drive module 30 can both be disposed on the fixture 10, the gripper 40 can be disposed on the drive module 30, and the connecting plate 50 can connect the translation module 20 and the drive module 30. In other words, the translation module 20 and the drive module 30 are disposed between the fixture 10 and the connecting plate 50.

[0025] In one embodiment, an optical component OD is used as an example. The optical component OD may include a lens 1, a circuit board 2, and a sensing element Im. The optical component OD can be placed on a fixture 10 and positioned and aligned on the fixture 10. The circuit board 2 can be disposed in the XY plane, the sensing element Im can be disposed on the circuit board 2, and the lens 1 can be disposed in the positive Z-axis direction of the sensing element Im. The calibration device 100 can detect whether there is a misalignment between the lens 1 and the sensing element Im, and adjust the axis of the lens 1 and the sensing element Im according to the misalignment, so that the center of the sensing surface of the sensing element Im falls on the optical axis of the lens 1, and then the optical component OD is assembled. The light beam passing through the lens 1 can be imaged on the sensing surface of the sensing element Im, and the misalignment can refer to the distance between the position of the light beam imaged on the sensing surface and the center point of the sensing surface.

[0026] In one embodiment, the drive module 30 may include a clamping part 310 and a drive part 320. In a specific embodiment, the drive module 30 may be a cylinder that uses compressed air as power, and the drive part 320 may be a cylinder body that has a channel for compressed air to enter or exit, thereby controlling the opening and closing of the clamping part 310. Specifically, the clamping part 310 may perform opening and closing movements relatively closer to or further away from the clamping direction DC in the XY plane, wherein there is an angle between the clamping direction DC and the X-axis, so the movement of the clamping part 310 in the clamping direction DC is simultaneously relative to both the X-axis and the Y-axis. In a specific embodiment, the angle may be 45°.

[0027] The gripper 40 can be fixedly connected to the drive module 30 and driven by the drive module 30 to reciprocate along the clamping direction DC. The gripper 40 may include a clamping part 410 and a connecting part 420 connected to each other. In one specific embodiment, the clamping part 410 may be substantially orthogonal L-shaped, and the gripper 40 can clamp the circuit board 2 of the optical component OD by means of the clamping part 410. In this way, the clamping part 410 can provide uniform clamping force on each side of the circuit board 2. The connecting part 420 of the gripper 40 can be fixedly disposed in the clamping part 310 of the drive module 30. By controlling the opening and closing of the clamping part 310, the gripper 40 can clamp or release the circuit board 2 along the clamping direction DC.

[0028] The connecting plate 50 is fixedly connected to the drive module 30 and the translation module 20. The connecting plate 50 can move along a first axis in the X-axis direction and a second axis in the Y-axis direction via the translation module 20, wherein the first axis and the second axis can be substantially orthogonal. Through this connection, the drive module 30 and the gripper 40 can move synchronously on the X-axis and / or Y-axis due to the linkage of the connecting plate 50, thereby driving the optical component OD held by the gripper 40 to move on the X-axis and / or Y-axis.

[0029] Here, the clamping direction DC of the gripper 40 can be moved along the X-axis and / or Y-axis directions by means of the connecting plate 50. Further, the clamping direction DC is not parallel or perpendicular to the X-axis and Y-axis, but has an offset angle with the X-axis and Y-axis, for example, any angle between 0 degrees and less than 90 degrees, thus offsetting the clamping direction DC from the X-axis and Y-axis. In one embodiment, the clamping direction DC can be set to be parallel to the diagonal direction of the circuit board 2.

[0030] In one embodiment, the calibration device 100 may further include a base 60. The base 60 may include a top seat 610, a side support seat 620, and a base 630. The side support seat 620 is connected between the top seat 610 and the base 630. The fixture 10 and the translation module 20 may be disposed on the base 60, for example, fixed to the top seat 610.

[0031] In one embodiment, the translation module 20 may include a first translation mechanism 210 and a second translation mechanism 220. The first translation mechanism 210 may include a first driving part 211, a first fixing part 212, and a first moving part 213, and the second translation mechanism 220 may include a second driving part 221, a second fixing part 222, and a second moving part 223. From the negative Z-axis to the positive Z-axis, the second moving part 223, the second fixing part 222, the first moving part 213, and the first fixing part 212 are arranged in sequence, wherein the first fixing part 212 may be fixed to the top seat 610 of the base 60, the first moving part 213 may be disposed on the first fixing part 212, and the second fixing part 222 may be fixed to the first moving part 213. The first driving part 211 may drive the first moving part 213 to move relative to the first fixing part 212 in the X-axis direction, and the second driving part 221 may drive the second moving part 223 to move relative to the second fixing part 222 in the Y-axis direction. The first drive unit 211 may be a motor, and / or the second drive unit 221 may be a motor.

[0032] The connecting plate 50 can be fixed to the translation module 20 via the second translation mechanism 220. Specifically, the connecting plate 50 can be fixed to the second moving part 223 of the second translation mechanism 220. When the first driving part 211 drives the first moving part 213 to move along the X-axis, it can simultaneously drive the second translation mechanism 220 and the connecting plate 50 to move along the X-axis; when the second driving part 221 drives the second moving part 223 to move along the Y-axis, it can simultaneously drive the connecting plate 50 to move in the Y-axis direction. In this way, the driving module 30 and the gripper 40 can move synchronously in the X-axis and Y-axis directions, thereby driving the optical component OD held by the gripper 40 to move in the X-axis and Y-axis directions.

[0033] The calibration device 100 may further include a control module 80. The control module 80 is electrically connected to the translation module 20. The first translation mechanism 210 and the second translation mechanism 220 can move along the X-axis and Y-axis respectively by means of the control module 80. Further, the control module 80 may include a controller 810 and a driver 820. Control signals issued by the controller 810 can be transmitted by the driver 820 to the first drive unit 211 and the second drive unit 221 to drive the first moving unit 213 to move in the X-axis direction and drive the second moving unit 223 to move in the Y-axis direction.

[0034] Furthermore, the calibration device 100 may include a light source module L. The top mount 610 may have an opening H extending through the Z direction, and the light source module L may be disposed at the opening H in the positive Z direction of the top mount 610. In practice, the optical component OD may be placed in the negative Z direction of the opening H. The light source module L may provide a light beam to the opening H to detect the lens 1 of the optical component OD. In one embodiment, the light source module L may include a light source and optical elements, wherein the optical elements may be a semi-circular diffuse mirror to provide detection light with uniform white brightness within the field of view of the lens 1.

[0035] The calibration device 100 may include a detection module 70. The detection module 70 may include a signal converter 710 and a signal processing unit 720. The signal converter 710 includes a first mounting base 711 and a first circuit board 712. The first mounting base 711 may be disposed on a base 60, for example, on the top seat 610 of the base 60. The first circuit board 712 is disposed on the first mounting base 711. The signal processing unit 720 includes a second mounting base 721 and a second circuit board 722. The second mounting base 721 may be disposed on the base 60, for example, on the base 630 of the base 60. The second circuit board 722 is disposed on the second mounting base 721.

[0036] The first circuit board 712 is electrically connected to the circuit board 2 and the second circuit board 722. The sensing element Im of the optical component OD can be set in the positive Z-axis direction of the circuit board 2. When the detection light passes through the lens 1 and generates an image signal on the sensing element Im, the image signal can be transmitted to the second circuit board 722 through the first circuit board 712. The second circuit board 722 can generate a detection image based on the image signal from the circuit board 2.

[0037] The calibration device 100 may further include a calculation module 90, which is electrically connected to the detection module 70 and the control module 80. The calculation module 90 can calculate the offset information of the sensing element Im based on the detection image generated by the second circuit board 722 and send it to the controller 810 of the control module 80. The controller 810 then generates corresponding control signals to drive the translation module 20 to move. The calculation module 90 may be a processing unit or a calculation unit, but is not limited thereto.

[0038] Figure 3 The diagram illustrates the placement and calibration of the optical component OD on fixture 10. (Refer to...) Figure 3 The fixture 10 may include a fixing plate 110 and a first positioning post 120. The first positioning post 120 is disposed on the fixing plate 110. The fixing plate 110 may have a through hole 130, and the lens 1 may be accommodated in the through hole 130.

[0039] Lens 1 may include a lens mount 11 and a lens 12. Lens 12 is disposed on lens mount 11, wherein lens mount 11 and lens 12 are connected to each other by threads. Lens 1 can pass through a through hole 130 in fixture 10, and the through hole 130 is designed with appropriate size and shape so that when lens 1 passes through through hole 130 in the positive Z-axis direction, lens 1 will not completely pass through fixture 10, but can be positioned on fixture 10. In addition, lens mount 11 may have a first set of upright holes 111 and a second positioning post 121.

[0040] The circuit board 2 may include a circuit board 21. The circuit board 21 may have a first positioning hole 22, a second positioning hole 24, and a second positioning hole 23. The first positioning hole 22 of the circuit board 2 is correspondingly provided with the first positioning post 120 of the fixture 10, and the second positioning hole 24 of the circuit board 2 is correspondingly provided with the second positioning post 121 of the lens 1. When the circuit board 2 and the lens 1 are disposed on the fixture 10 along the positive Z-axis direction, the first positioning post 120 of the fixture 10 is located in the first positioning hole 22 of the circuit board 2, and the second positioning post 121 of the lens 1 is located in the second positioning hole 24 of the circuit board 2, so that the circuit board 2 and the lens 1 are aligned with each other on the fixture 10.

[0041] The first set of mounting holes 111 of lens 1 corresponds to the second set of mounting holes 23 of circuit board 2. After the optical center of circuit board 2 is aligned, the optical assembly OD can be completed by screwing screw 3 into the second set of mounting holes 23 of circuit board 2 and the first set of mounting holes 111 of lens 1. The optical center adjustment method of circuit board 2 is described below.

[0042] Figure 4 A schematic diagram showing the gripper 40 holding the circuit board 2 from a top-down perspective; Figure 5 A schematic diagram showing the gripper 40 clamping the circuit board 2 from a top-down perspective.

[0043] Reference Figure 3 , Figure 4 and Figure 5 First, after the lens 1 is positioned on the fixture 10, the circuit board 2 is placed on the fixture 10. The circuit board 2 and the lens 1 can be aligned with each other on the fixture 10 by means of the first positioning post 120 and the first positioning hole 22, as well as the second positioning post 121 and the second positioning hole 24.

[0044] Then, the control drive module 30 drives the gripper 40 to clamp the circuit board 2 in the clamping direction DC.

[0045] Figure 6 and Figure 7 The calibration method for the optical center (OC) is illustrated. (Refer to...) Figure 1 , Figure 3 and Figure 6The calculation module 90 determines that the optical center OC of the sensing element 25 of the circuit board 2 and the optical axis OA of the lens 12 of the lens 1 are deviated based on the detection image IMG of the detection module 70. It then calculates the offset information between the optical center OC and the optical axis OA and transmits the offset information to the control module 80.

[0046] Reference Figure 1 , Figure 3 and Figure 7 Next, the control module 80 controls the translation module 20 to fine-tune the relative position of the circuit board 2 to the lens 1 based on the offset information. Here, the control module 80 controls the circuit board 2 to move in the X-axis and Y-axis directions, so that the optical center OC of the sensing element 25 is aligned with the optical axis OA of the lens 12, thus completing the adjustment of the optical center OC.

[0047] Figure 8 A top-down view showing the diagram after calibration at the optical center (OC). (Refer to...) Figure 3 and Figure 8 After adjusting the optical center OC, the circuit board 2 and lens 1 can be fixed together using screws 3 to complete the assembly of the optical component OD. Then, the drive module 30 is controlled to drive the gripper 40 to release the circuit board 2, and the optical component OD can be removed from the fixture 10.

[0048] Of course, there may be other embodiments of this utility model.
