Description

Technical Field

[0001] This utility model relates to the field of graphics card testing, and in particular to a high-efficiency graphics card solder joint quality testing device. Background Technology

[0002] The graphics card is one of the most basic components of a computer. It is responsible for converting and driving the display information required by the computer system, providing horizontal scanning signals to the monitor, and controlling the monitor to display correctly. In the manufacturing process of graphics cards, the quality of the solder joints is crucial, as it directly affects the electrical performance, stability, and lifespan of the graphics card. If there are quality problems such as poor soldering, short circuits, or insufficient solder, the graphics card may experience display abnormalities, unstable operation, or even failure to work properly. Therefore, the quality of the solder joints must be strictly inspected.

[0003] Currently, graphics card solder joint quality inspection typically involves placing the graphics card on a testing platform and using an industrial high-definition camera for imaging. However, after each inspection, the operator needs to manually remove the inspected graphics card before placing a new one for inspection. During this process, the testing equipment is idle, preventing continuous graphics card inspection and reducing the efficiency of solder joint quality inspection. To address these issues, we propose a high-efficiency graphics card solder joint quality inspection device. Utility Model Content

[0020] 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 scope of protection of the present utility model. Unless otherwise specified, the methods used in the present utility model are conventional methods; unless otherwise specified, the raw materials and apparatus used are conventional commercially available products.

[0021] The high-definition industrial camera, fill light, detection host and servo motor in this utility model are all common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0022] Please see Figure 1-4In this utility model, a high-efficiency graphics card solder joint quality inspection device includes a support base 1, a detection top plate 2 fixedly installed on the top of the support base 1, a first high-definition industrial camera 7 fixedly installed on the bottom surface of the detection top plate 2, two detection side plates 10 fixedly installed on the outer surface of the support base 1, and a second high-definition industrial camera 11 fixedly installed on the side of the two detection side plates 10 that are close to each other. A rotating disk 3 is provided on one side of the support base 1, a support plate 4 is fixedly connected to one side of the support base 1, a servo motor 5 is provided below the support plate 4, a rotating shaft 6 is fixedly installed at the output end of the servo motor 5, the top of the rotating shaft 6 is fixedly installed to the bottom surface of the rotating disk 3, and a ring of graphics card positioning seats 19 is fixedly installed on the upper surface of the rotating disk 3.

[0023] In this embodiment: the servo motor 5 drives the rotation of the rotating shaft 6, which in turn drives the rotating disk 3 to rotate. Therefore, the graphics card is placed above the graphics card positioning seat 19 and can move with the rotating disk 3. Through the first high-definition industrial camera 7 and the second high-definition industrial camera 11, the graphics card solder joints that have moved to the designated position can be photographed in high definition from different angles, realizing all-round inspection of the quality of the graphics card solder joints, ensuring the accuracy and comprehensiveness of the inspection. At the same time, the continuous rotation of the rotating disk 3, combined with the camera inspection, can make the inspection process uninterrupted and improve the inspection efficiency.

[0024] As a technical optimization of this utility model, the upper template of the support plate 4 is fixedly connected to the limiting slide 13, the bottom surface of the rotating disk 3 is fixedly connected to the annular slide rail 14, the outer surface of the annular slide rail 14 is slidably connected to the inner wall of the limiting slide 13, a support plate 8 is fixedly installed on one side of the support base 1, a supplementary light 9 is fixedly installed on one side of the support plate 8, and a detection host 12 is fixedly installed on the outer surface of the support base 1. The detection host 12 communicates in real time with the first high-definition industrial camera 7 and the second high-definition industrial camera 11 through a data cable, and receives the weld point image data captured by the two sets of cameras from the top and side. The detection host 12 first performs grayscale conversion and filtering on the original image. The system has a built-in three-dimensional model database of standard weld points. The detection host 12 extracts the shape, size, gloss and other feature parameters of the weld points through the edge detection algorithm, performs pixel-level comparison with the standard template, and calculates the offset and difference value. A counterweight base 16 is fixedly installed on the bottom surface of the support base 1.

[0025] In this embodiment: the sliding cooperation between the annular slide rail 14 and the limiting slide block 13 can limit the shaking of the rotating disk 3 during rotation and ensure its rotational stability. The setting of the supplementary light 9 can provide uniform and stable light for camera shooting, improve the clarity and quality of the captured image. The detection host 12 is responsible for receiving and processing the image data captured by the camera and quickly judging the quality of the graphics card solder joints. The counterweight base 16 increases the overall stability of the device.

[0026] As a technical optimization of this utility model, a bearing 18 is fixedly embedded on the upper surface of the support plate 4, the outer surface of the rotating shaft 6 is rotatably connected to the inner ring of the bearing 18, two fixing blocks 17 are fixedly installed on the outer surface of the support plate 4, and the sides of the two fixing blocks 17 that are close to each other are fixedly connected to the outer surface of the servo motor 5. A reinforcing inclined plate 15 is fixedly installed on one side of the support base 1, and the upper surface of the reinforcing inclined plate 15 is fixedly connected to the bottom surface of the support plate 4.

[0027] In this embodiment: the rotational connection between the bearing 18 and the rotating shaft 6 reduces the friction when the rotating shaft 6 rotates; the servo motor 5 can be stably installed on the bottom surface of the support plate 4 by the fixing block 17; and the load-bearing capacity and structural strength of the support plate 4 are enhanced by the setting of the reinforcing inclined plate 15.

[0028] The working principle of this utility model is as follows: When in use, the bottom of the graphics card is inserted into the graphics card positioning base 19. Then, the servo motor 5 is started, which enables the rotating shaft 6 to drive the rotating disk 3 to rotate. When the rotating disk 3 rotates to the designated position, it stops working. The first high-definition industrial camera 7 on the bottom surface of the top plate 2 and the second high-definition industrial camera 11 on the side plate 10 start working, which can take pictures and inspect the graphics card solder joints from different angles. The supplementary light 9 provides sufficient and uniform light to ensure that the picture is clear. Then, the detection host 12 receives the image data captured by the camera, analyzes and processes it, and judges the quality of the solder joints. While one graphics card is being inspected, two operators can place new graphics cards and remove the inspected graphics cards at other positions on the rotating disk 3, so as to realize the simultaneous loading and inspection.

[0029] However, the above description is merely a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
