[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-3 The chip placement slot detection device shown includes a support plate 2 and a fixing block 3 installed at the rear end of the support plate 2; A tape camera 1 is installed on the front side of the support plate 2, and a light source 11 is installed on the lower side of the tape camera 1. The chip to be tested is placed on the upper side of the light source 11 and the lower side of the tape camera 1 through an external conveying mechanism. The light source 11 is turned on, and its light intensity and angle are adjusted to provide uniform and suitable illumination to the surface of the chip placement slot. The tape camera 1 is started and takes pictures of the chip placement slot according to the preset parameters to acquire image data. During the shooting process, the clarity and completeness of the images captured by the camera are checked. If there are any abnormalities, the camera parameters are adjusted in time or the pictures are retaken. The image data captured by the tape camera 1 is quickly transmitted to the data processing device through the data transmission interface. The extracted feature information is compared and analyzed in detail with the standard templates and parameters in the database. Based on the comparison results, it is determined whether the chip placement slot is qualified. If all the parameters of the chip placement slot are within the allowable tolerance range and there are no obvious defects, it is judged as a qualified product. If there are dimensional deviations, pin defects, surface problems, etc., it is judged as a non-qualified product, and the specific location and type of the problem are marked on the image, such as the specific pin number of the bent pin, the location and length of the scratch, etc.

[0020] like Figure 1 As shown, a connecting support 8 is fixedly connected to the front outer wall of the support plate 2 to support the tape camera 1.

[0021] The connecting support 8 mainly bears the main lifting force, ensuring the vertical stability of the tape camera 1 so that it can be accurately aligned with the detection area of ​​the chip placement slot.

[0022] like Figure 1 As shown, a lighting bracket 5 is fixedly connected to the lower outer wall of the support plate 2 to limit the position of the light source 11.

[0023] The lighting bracket 5 ensures that the light source 11 can be accurately positioned below the tape camera 1, so that the light emitted by the light source 11 can evenly illuminate the chip placement slot at a suitable angle and intensity.

[0024] like Figure 1 As shown, a camera 10 is provided on the right side of the tape camera 1, and a lens 9 is fixedly connected to the lower outer wall of the camera 10.

[0025] The lens 9 of the camera 10 has a specific focal length and angle of view, and can acquire image information from a different angle or with a different focus than that of the tape camera 1. For example, it may focus more on the overall outline of the chip placement slot, the macroscopic features of certain specific parts, etc.

[0026] like Figure 1As shown, a pocket-position camera mounting base 6 is fixedly connected between the rear outer wall of the camera 10 and the support plate 2. A connecting support frame 7 is fixedly connected to the front outer wall of the support plate 2 to assist in supporting the tape camera 1. A camera bracket 4 is fixedly connected to the lower outer wall of the pocket-position camera mounting base 6 to support the camera 10. The lower outer wall of the camera 10 is connected to the camera bracket 4 via the lens 9. The camera bracket 4 is fixed to the lower outer wall of the camera mount 6 in the pocket position, while the rear outer wall of the camera mount 6 in the pocket position is fixedly connected to the support plate 2, forming a stable support and fixing system to ensure that the camera 10 maintains a stable position and attitude when working.

[0027] like Figure 2 and Figure 3 As shown, both the tape camera 1 and the camera 10 have data connection ports on their upper outer walls.

[0028] The data connection port is used to transmit digital image data generated by the camera to external data processing equipment. Through the data connection port, the image data acquired by the camera can be transmitted to the data processing equipment in real time or near real time, providing timely data support for subsequent data processing and analysis.

[0029] The implementation principle of this embodiment is as follows: The chip to be tested is placed on top of the light source 11 and below the tape camera 1 via an external conveying mechanism. The light source 11 is turned on, and its light intensity and angle are adjusted to provide uniform and suitable illumination to the surface of the chip placement slot. The tape camera 1 is started and takes pictures of the chip placement slot according to preset parameters to acquire image data. During the shooting process, the clarity and completeness of the images captured by the camera are checked. If any abnormalities are found, the camera parameters are adjusted or the pictures are retaken. The image data captured by the tape camera 1 is quickly transmitted to the data processing device through the data transmission interface. The extracted feature information is compared and analyzed in detail with the standard templates and parameters in the database. Based on the comparison results, it is determined whether the chip placement slot is qualified. If all parameters of the chip placement slot are within the allowable tolerance range and there are no obvious defects, it is judged as a qualified product. If there are dimensional deviations, pin defects, surface problems, etc., it is judged as a non-qualified product, and the specific location and type of the problem are marked on the image, such as the specific pin number of the bent pin, the location and length of the scratch, etc.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
