Description

Technical Field

[0001] This utility model relates to the field of graphics card testing, and more specifically, to a device for testing the heat resistance of graphics cards. Background Technology

[0002] A graphics card, also known as a display interface card or display adapter, is one of the most basic and important components of a computer. As the computing power of computer graphics cards has gradually increased, their power consumption and heat generation have also increased. Therefore, graphics cards need to be tested for heat resistance after production.

[0003] To improve testing efficiency, manufacturers often use testing devices. For example, a Chinese national patent discloses a graphics card heat resistance testing device (application number: CN201922494152.2). This device works by inserting the graphics card into a graphics card slot, then a moving motor drives gears to rotate, which in turn moves the moving frame and the graphics card. When the graphics card moves to the graphics card heating and testing component, the moving motor stops working, and the graphics card heating and testing component heats the graphics card and tests its heat resistance. At the same time, a rotating motor drives the drive wheel to rotate, which in turn drives the rotating shaft through a belt sleeve and a driven wheel. The rotating shaft causes the graphics card inserted in the slot to rotate, achieving uniform heating. However, after the graphics card is inserted into the slot, most of the graphics card is suspended in the air. The graphics card is affected by gravity, plus the force when the graphics card moves, and the force of rotation when the graphics card is heated. This makes the graphics card easy to bend or deform at the point where it is inserted into the slot, resulting in a defective graphics card. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0019] Examples of embodiments of this utility model Figures 1 to 3 As shown, a graphics card heat resistance testing device includes a testing housing 1 and a conveyor belt device 2. The testing housing 1 extends in a left-right direction, and a support 20 is provided at the bottom end of the testing housing 1. The conveyor belt device 2 passes through the testing housing 1. The opposite sides of the testing housing 1 are open structures to avoid the conveyor belt device 2 and the graphics card, that is, the left and right ends of the testing housing 1 are open structures. The conveyor belt of the conveyor belt device 2 is made of a high-temperature resistant material, such as 316L stainless steel fiber metal cloth and galvanized steel wire metal mesh conveyor belt, etc. Preferably, the conveyor belt of the conveyor belt device 2 is made of a high-temperature resistant material. The detection housing 1 has a mesh structure to avoid affecting the heating of the bottom of the graphics card. A heating tube 3 is provided on the inner wall of the detection housing 1. The heating tube 3 extends along the inner side wall of the detection housing 1 in a ring structure. When the detection housing 1 is a hollow cuboid, the heating tube 3 has a square ring structure. When the detection housing 1 is a hollow cylindrical tube, the heating tube 3 has a circular ring structure. The square or circular ring structure of the heating tube 3 makes the graphics card heat more evenly. A graphics card detection mechanism is provided inside the detection housing 1. A cooling mechanism is provided at one end of the conveyor belt device 2 that extends out of the detection housing 1.

[0020] The conveyor belt device 2 transports the graphics card into the testing housing 1, where it is heated by the heating pipe 3. The graphics card is then tested by the graphics card testing mechanism. After the test is completed, the conveyor belt device 2 moves the graphics card out of the testing housing 1, and the cooling mechanism cools down the graphics card. This testing device moves the graphics card by the conveyor belt device 2, so that the graphics card is not suspended in the air, thereby avoiding the graphics card from deforming and becoming defective.

[0021] Further improvements, such as Figure 2 and Figure 3 As shown, multiple heating tubes 3 are provided, and the multiple heating tubes 3 are arranged on the inner side wall of the detection shell 1. The multiple heating tubes 3 are arranged at equal intervals along the conveying direction of the conveyor belt device 2. In this embodiment, four heating tubes 3 are provided, and the four heating tubes 3 are arranged at equal intervals from left to right. At the same time, in this embodiment, the detection shell 1 is a cuboid structure extending in the left and right direction, and the heating tubes 3 are square ring structures. The conveyor belt device 2 passes through the multiple heating tubes 3 in sequence, thereby improving the heating efficiency inside the detection shell 1.

[0022] Further improvements, such as Figure 2 and Figure 3 As shown, a connecting rod 4 is provided on the inner wall of the detection housing 1. The connecting rod is located on the inner top wall of the detection housing 1.

The temperature sensor 40 is electrically connected to multiple heating tubes 3. The temperature inside the detection housing 1 is detected by the temperature sensor 40 to prevent the temperature inside the detection housing 1 from exceeding the maximum heat resistance temperature of the graphics card and to avoid unnecessary damage to the heat resistance performance of the graphics card during testing.

[0023] Further improvements, such as Figure 1 and Figure 3 As shown, the graphics card detection mechanism includes a first camera 5, a second camera 50, and a lifting robot arm 51.

That is, the lifting robot arm 51 raises the graphics card to expose its bottom surface for the second camera 51 to capture and detect. The first camera 5 and the second camera 50 detect whether the graphics card has changed its appearance due to heat. Both the first camera 5 and the second camera 50 are detection cameras containing CCD sensors. Preferably, the conveyor belt of the conveyor belt device 2 is provided with a placement area mark. The graphics card is placed in the placement area mark, and the lifting robot arm 51 picks up the graphics card from the placement area mark. At the same time, the lifting robot arm 51 has a rotatable structure, which facilitates the lifting robot arm 51 to pick up graphics cards in different postures.

[0024] Further improvements, such as Figure 1 and Figure 3As shown, a partition plate 6 is provided inside the detection housing 1, which divides the detection housing 1 into a heating zone and a detection zone. The partition plate 6 is provided with a first clearance notch 60 for the conveyor belt device 2 and the graphics card. The heating pipe 3 and the graphics card detection mechanism are respectively arranged in the heating zone and the detection zone. The partition plate 6 blocks the heat in the heating zone, thereby reducing the impact of the heat in the heating zone on the graphics card detection mechanism in the detection zone.

[0025] Further improvements, such as Figure 2 and Figure 3 As shown, a baffle 7 is provided on the detection housing 1. The baffle 7 covers the opening of the detection housing 1 in the heating zone. The baffle 7 is provided with a second clearance notch 70 to avoid the conveyor belt device 2 and the graphics card. The baffle 7, together with the partition plate 6, blocks the heat in the heating zone and prevents the heat in the heating zone from escaping, thereby reducing the working time of the heating tube 3, accelerating the heating rate in the heating zone, and saving energy.

[0026] Further improvements, such as Figure 1 and Figure 2 As shown, the cooling mechanism includes multiple fans 8, which are arranged sequentially along the conveying direction of the conveyor belt device 2.

Three fans 8 are provided, and the three fans 8 are arranged at equal intervals from left to right on the top surface of the mounting plate. The fans 8 are cooling fans, and the three cooling fans cool down the tested graphics card, thereby facilitating the subsequent processing of the graphics card, such as other tests of the graphics card or packaging of the graphics card.

[0027] Further improvements, such as Figure 1 and Figure 3 As shown, a control box 9 is also provided at one end of the conveyor belt device 2 that extends out of the detection housing 1.
