[0003] In semiconductor manufacturing processes, cameras are needed to acquire two-dimensional images of heat sinks. Because the camera system uses a coaxial light source design and its front-end heat sink is made of stainless steel, factors such as light pollution and changes in the heat sink material can cause the camera to have insufficient performance when reading two-dimensional images, resulting in blurry images and a defect rate of 39%. This ultimately affects production efficiency and increases costs.

[0033] Please see Figure 1-2 This embodiment provides a camera imaging auxiliary light source device for assisting camera 100 in imaging a heat sink 200. The camera 100 is mounted on a robotic arm 300, and the heat sink 200 has a preset imaging area. The acquisition end of the camera 100 is positioned facing the imaging area of the heat sink 200. The camera imaging auxiliary light source device includes:
[0034] The first bracket 1 is mounted on the robotic arm 300 and is spaced apart from the camera 100.
[0035] The second bracket 2 has a first end and a second end that are disposed opposite to each other, and the first end of the second bracket 2 is rotatably connected to the first bracket 1.
[0036] Lighting device 3 is installed at the second end of the second bracket 2;
[0037] The output end of the illuminator 3 is positioned toward the imaging area of the heat sink 200, so that when the illuminator 3 is turned on, the imaging area of the heat sink 200 is illuminated by the illuminator 3.
[0038] With regard to the above structure, during installation, the mounting height or horizontal position of the first bracket 1 on the robotic arm 300 can be adjusted as needed, and the rotation angle of the second bracket 2 relative to the first bracket 1 can be adjusted in coordination, so that the light source emitted by the illuminator 3 is directed toward the preset imaging area.
[0039] With the above structure, during use, the operator only needs to place the heat sink 200 to be tested in the corresponding area, correct the direction of the light source emitted by the illuminator 3 and the imaging position of the camera 100, and then simultaneously start the camera 100 and the illuminator 3. The illuminator 3 covers the imaging area with light, increasing the brightness of the imaging area. At this time, the image quality of the area captured by the camera 100 is improved, avoiding the influence of factors such as light pollution and changes in heat sink material. The original image reading defect rate was 39%, and now the image reading defect rate is 0%. At the same time, with the combination of the first bracket 1 and the second bracket 2, the illuminator 3 at the end of the second bracket 2 can be rotated and the angle can be adjusted to adapt to different sizes, achieving a wider range of test scenarios. It can also temporarily fine-tune the lighting effect to achieve the best imaging effect.
[0040] like Figure 2 As shown, the camera 100 in the above embodiment can be configured as an image acquisition device with a acquisition lens at one end. Specifically, the camera 100 itself is not limited to a general camera; it can be a single-lens camera connected to an external source via a transmission line, or a dynamic image acquisition camera, etc., as long as it can meet the requirements for image acquisition of its bottom position. The specific imaging area on the heat sink 200 is set directly below the position of the lens of the camera 100. The camera 100 has a preset focal length and imaging range, so that the camera 100 can just capture at least the top surface area of the heat sink 200, including the imaging area.
[0041] The back of the camera 100 has screw holes for mounting fasteners, and the second bracket 2 includes another matching screw hole. By inserting the corresponding fasteners into the screw holes of the camera 100 and the second bracket 2, a secure fastener connection can be formed between the back of the camera and the second bracket 2. Of course, in some other embodiments, the connection between the camera 100 and the second bracket 2 can be adhesive, snap-fit, or direct welding, which can be set as needed.
[0042] The first bracket 1 and the second bracket 2 are also provided with corresponding mounting holes. For example, in this embodiment, the first bracket 1 is provided with a first mounting hole, and the second bracket 2 is provided with a second mounting hole 21. A fastener is detachably inserted into the first mounting hole and the second mounting hole 21 so that the first bracket and the second bracket are fixed to each other.
[0043] Of course, in other embodiments, the connection between the first bracket 1 and the second bracket 2 can be achieved by adhesive bonding, snap-fit connection, or direct welding, which can be set as needed. Considering that the fastener installation method allows for flexible rotation of the second bracket 2 before locking and fixing, thus achieving angle adjustment, a fastener fixing method is adopted in the preferred embodiment.
[0044] The first bracket 1 also has a long strip-shaped fixing plate on the side opposite to the second bracket 2, such as... Figure 1 As shown, the number of long strip-shaped fixing plates can be two spaced apart. They are fixed by fasteners at the four corners, which can effectively maintain the stability of the entire first bracket 1.
[0045] Specifically, in this embodiment, the projection surface of the elongated fixed plate of a certain length can at least cover the entire area of the camera 100 and the second bracket 2, thus providing optimal stability and avoiding shaking.
[0046] The angle between the first bracket 1 and the second bracket 2 is not 0 degrees or 180 degrees, so that when the illuminator 3 is turned on, the imaging area of the heat sink 200 is obliquely illuminated by the illuminator 3. In other words, the setting of the camera imaging auxiliary light source device does not actually affect the original camera 100, the structural changes are small, it is easy to construct, and the oblique setting can obtain a more uniform and gentle light source surface, avoiding overexposure.
[0047] Taking a preferred embodiment as an example, the angle between the first bracket 1 and the second bracket 2 in this embodiment is 60 degrees, which allows the light to cover the imaging area of the corresponding heat sink 200 relatively evenly, and the bending angle saves space.
[0048] Furthermore, the first bracket 1 is provided with a first mounting hole, and the second bracket 2 is provided with a second mounting hole 21. A fastener is detachably inserted into the first mounting hole and the second mounting hole 21 to fix the first bracket and the second bracket to each other. When it is necessary to rotate the angle between the first bracket 1 and the second bracket 2, rotating the second bracket 2 will achieve the angle change around the second mounting hole 21. At the same time, in this embodiment, the second bracket 2 is also provided with a third mounting hole 22, and the third mounting hole 22 is spaced apart from the second mounting hole 21. Therefore, the second mounting hole 21 or the third mounting hole 22 can be flexibly selected to assemble with the first bracket 1 to achieve different height adjustments and obtain a wider range of adaptability.
[0049] Furthermore, the second mounting hole 21 is set as an arc-shaped waist hole. That is to say, in this embodiment, the second bracket 2 can be fixed through different positions of the waist hole to achieve more angles of assembly, and the illuminator 3 can be extended forward or retracted.
[0050] Of course, in some other embodiments, considering the need for cost control, the second mounting hole 21 can be set as a regular rectangular hole.
[0051] Furthermore, the horizontal height of the illuminator 3 is the same as the horizontal height of the camera 100. The above setting is the result of the installation and rotation adjustment of the second bracket 2. That is to say, in this embodiment, since the horizontal height of the illuminator 3 is the same as the horizontal height of the camera 100, the direct impact of the light source of the illuminator 3 on the lens of the camera 100 is avoided, thus avoiding glare and also avoiding insufficient brightness due to excessive distance.
[0052] Furthermore, the angle between the first bracket 1 and the second bracket 2 is 55-65 degrees. Simultaneously, the illuminance of the illuminator 3 is 15,000-25,000 lux. Most preferably, the angle between the first bracket 1 and the second bracket 2 is 60 degrees. Simultaneously, the illuminance of the illuminator 3 is 20,000 lux. Under these conditions, optimal lighting effect is achieved, and the light coverage is uniform, resulting in good image acquisition performance from the camera 100.
