Description

Technical Field

[0001] The present application relates to camera assembly technology, and in particular to a camera module centering tooling. Background Art

[0002] During the assembly of the camera module, the camera module needs to be actively aligned (AA). This process adjusts the relative position of the lens or the sensor, and detects the imaging effect of the chart in real time to ensure that the optical axis of the lens and the vertical axis of the sensor surface are concentric, and the lens is at the best focusing position on the sensor. Then, the lens and the sensor are fixed by UV curing or welding.

[0003] At present, there are two main ways to actively adjust the camera module: upward AA and downward AA. Among them, upward AA means that the image card and the lens are facing downward, the lens is fixed, and the position and angle of the photosensitive chip are adjusted; downward AA means that the image card and the lens are facing upward, the photosensitive chip is fixed, and the position and angle of the lens are adjusted.

[0043] Please refer to Figure 1-Figure 7 This embodiment provides a camera module centering tool, including:

[0044] The optical platform 100 can be arranged on the support part 110. The support part 110 can provide stable support for the optical platform 100 on the one hand, and can lift the optical platform 100 to a certain height on the other hand to meet the needs of ergonomics and facilitate the use of the user. The support part 110 can include a plurality of vertically arranged support columns, and adjacent support columns can also be connected by horizontally arranged connecting columns to improve stability. The lower end of the support part 110 can also be provided with a support foot and a universal wheel, the support foot facilitates the stable contact between the support part 110 and the ground, and the universal wheel facilitates the movement of the optical platform 100. In other embodiments, the optical platform 100 can also be a shock-absorbing platform including a shock absorber.

[0045] The chart card assembly 200 is detachably or rotatably mounted on the optical platform 100, so as to facilitate the change of the relative position of the chart card assembly 200 and the optical platform 100. The chart card assembly 200 includes at least one optical element, and the optical element may include a parallel light pipe 211. The chart card assembly 200 can provide standard test images and patterns during the active centering process of the camera module. By observing and analyzing the chart card images and patterns taken by the camera, the performance of the camera module in terms of focus, contrast, clarity, grayscale and image uniformity can be judged, so as to make corresponding adjustments and optimizations as needed.

[0046] The first clamping mechanism 300 is disposed on the optical platform 100 and is used to clamp one of the lens or the photosensitive chip to ensure the stability of the lens or the photosensitive chip during the active centering process of the camera module.

[0047] The second clamping mechanism 400 is disposed on the optical platform 100 and is used to clamp the other of the lens or the photosensitive chip to ensure the stability of the lens or the photosensitive chip during the active centering process of the camera module.

[0048] In this embodiment, the first clamping mechanism 300 and the second clamping mechanism 400 can both move or rotate in three-dimensional space, so that the position of the lens or photosensitive chip can be adjusted in combination with the image card assembly 200 to achieve the process of active centering of the camera module.

[0049] like Figure 1 and Figure 2 As shown, the chart assembly 200, the first clamping mechanism 300 and the second clamping mechanism 400 of this embodiment have a relative first state and a second state with the optical platform 100, and the optical element is arranged toward the first clamping mechanism 300 and the second clamping mechanism 400, so as to provide a standard test pattern to the lens or the photosensitive chip.

[0050] Specifically, in the first state, the first clamping mechanism 300 is used to clamp the photosensitive chip, and the second clamping mechanism 400 is used to clamp the lens, and the lens is located between the optical element and the photosensitive chip. At this time, the first clamping mechanism 300 for clamping the photosensitive chip can be fixed, and the second clamping mechanism 400 for clamping the lens moves, thereby meeting the upward AA requirement.

[0051] In the second state, the first clamping mechanism 300 is used to clamp the lens, and the second clamping mechanism 400 is used to clamp the photosensitive chip. The lens is located between the optical element and the photosensitive chip. At this time, the first clamping mechanism 300 for clamping the lens can be fixed, and the second clamping mechanism 400 for clamping the photosensitive chip moves, thereby meeting the downward AA requirement.

[0052] It should be noted that the chart card assembly 200, the first clamping mechanism 300 and the second clamping mechanism 400 in this embodiment can be vertically arranged as required (for example Figure 1 and Figure 2 as shown) or mounted horizontally on the optical platform 100.

[0053] When the image card assembly 200 is detachably mounted on the optical platform 100 , the position of the image card assembly 200 can be changed by removing the image card assembly 200 , rotating it by a certain angle (eg, 180°), and then reinstalling it on the optical platform 100 .

[0054] When the card assembly 200 is rotatably mounted on the optical platform 100, the card assembly 200 can be connected using structures such as a motor and a rotating shaft to drive the card assembly 200 to rotate a certain angle (e.g., 180°) relative to the optical platform 100, thereby changing the position of the card assembly 200.

[0055] It is understandable that the first clamping mechanism 300, the second clamping mechanism 400 and the optical platform 100 can also be connected in a detachable or rotatable manner, so as to enable the chart assembly 200, the first clamping mechanism 300, the second clamping mechanism 400 and the optical platform 100 to switch between the first state and the second state.

[0056] From the above description, it can be known that in this embodiment, the relative states between the image card assembly 200, the first clamping mechanism 300, the second clamping mechanism 400 and the optical platform 100 are adjusted so that the tooling meets the requirements of upward AA or downward AA, so that one tooling can be compatible with upward AA or downward AA, which is beneficial to reduce production costs.
