Referring to fig. 1 and 2, the IC surface appearance line scanning detection device of the embodiment of the utility model is characterized by comprising a CCD camera 1, a lens barrel 2, a point light source 3 and a sliding table 4, wherein the CCD camera 1 is connected with the lens barrel 2 through threads, the point light source 3 is disposed on a side surface of the lens barrel 2, and the lens barrel 2 is disposed on the sliding table 4 through a fixing member 21 and a clamping block 22.

In the above embodiment, the CCD camera 1 can be stably fixed to the lens barrel 2 by screw connection. This connection ensures a tight fit between the camera and the lens barrel 2, thereby reducing the possibility of image distortion or blurring, and the point light source 3 is placed at the side of the lens barrel 2. When an object or a scene needs to be shot or recorded, the light rays emitted by the point light source 3 firstly pass through the lens barrel 2, so that the shot object or the scene is ensured to be uniformly and intensively illuminated. The slide table 4 is not only a supporting structure of the lens barrel 2, but also a main moving and positioning device of the entire optical system. The lens barrel 2 can be stably fixed on the slide table 4 by the fixing piece 21 and the clamp block 22. The slide table 4 can precisely move the lens barrel 2 so as to be aligned with the point light source 3 and the CCD camera 1, ensuring that light can be accurately transmitted to the camera and a clear image can be formed. When it is desired to photograph or record an object or scene, the point light source 3 emits light. The light is transmitted through the lens barrel 2, ensuring that the subject or scene is properly illuminated. The slide table 4 moves and positions the lens barrel 2 as needed, ensuring that light is accurately transmitted to the CCD camera 1. The CCD camera 1 senses light and forms an image through a Charge Coupled Device (CCD) inside thereof. The formed image may be recorded, transferred or further processed for IC surface inspection. In summary, this configuration forms a fully functional, movable and positionable optical system by combining the CCD camera 1, the lens barrel 2, the point light source 3, and the slide table 4. The system can shoot and record high-quality images, and is suitable for various occasions requiring high-precision and definition imaging.

Referring to fig. 1 and 2, in another embodiment, the relative positions of the CCD camera 1 and the point light source 3 are adjustable.

In the above embodiment, the CCD camera 1 and the point light source 3 are mounted on respective brackets or stages, which can adjust the position and angle. By rotating or translating these mechanical structures, the relative position between the camera and the light source can be changed. As the relative positions of the camera and the light source change, the optical relationship between them will also adjust accordingly. Such adjustment may affect the angle at which the light impinges on the target object, the path of the light, and the amount of light that eventually reaches the CCD sensor 5.

Referring to fig. 1 and 2, in another embodiment, the fixing member 21 and the clamping block 22 are detachable.

In the above embodiments, when the fixing member 21 or the clamping block 22 is worn, damaged or needs cleaning, it can be easily detached for replacement or repair. This avoids the situation of replacing the whole apparatus due to damage of the fixing member 21, saving costs and time. In some cases, it may be necessary to fine-tune or recalibrate the fixing member 21 or the clamp block 22 according to the actual use of the lens barrel 2. By means of the detachable design, the user can easily detach and reinstall the fixing element 21 or the clamping block 22 when needed, so that precise adjustment of the device is achieved.

Referring to fig. 1 and 2, in another embodiment, the CCD camera 1 includes an image sensor 11, a lens 12, and an interface 13, wherein the image sensor 11 is used for receiving an image of a surface of the detected IC, the lens 12 is used for focusing the image onto the image sensor 11, and the interface 13 is used for transmitting image data to an external device.

In the above-described embodiment, the image sensor 11 is used to receive an image focused by the lens 12. The image sensor 11 converts the light into an electrical signal providing raw data for subsequent image processing and data transmission. The function of the lens 12 is to focus the image of the IC surface onto the image sensor 11, ensuring that the image is clear and accurate. The quality and configuration of the lens 12 directly affects the resolution and sharpness of the final image. The interface 13 is a channel connecting the CCD camera 1 with an external device, and is responsible for transmitting image data. The image data may be transmitted in real time or afterwards to a computer, controller 43 or other external device via interface 13 for further processing, analysis and storage.

Referring to fig. 1 and 2, in another embodiment, the sliding table includes a main body, a sliding track, and a fixing device, where the main body is slidably disposed on the sliding track, and the fixing device is used to fix the main body to the sliding track.

In the above embodiment, the main body is manually adjusted to move on the slide way, so as to further adjust the sliding table, adjust the CCD camera to an optimal shooting angle and height, and fix the main body on the slide way through the fixing device, so as to stabilize the shooting angle of the CCD camera, and the fixing device may be fixed through knob control or bolt type fixing, which is not limited.
