[0016] As Figures 1-3 shown, the utility model provides a device for detecting the curvature of a display heat dissipation aluminum plate, including a frame body 1, a detection cavity 2 arranged in the frame body 1, and a screw rod 4 arranged parallel to the length direction of the detection cavity 2. The thread directions at both ends of the screw rod 4 are opposite. A driving member 8 for driving the screw rod 4 to rotate is installed on the frame body 1. Sliding blocks 5 are threadedly connected to both ends of the screw rod 4. A linear guiding structure for the sliding blocks 5 is provided on the frame body 1. A limiting plate 7 is connected to the sliding blocks 5. The detection cavity 2 has the same width as the heat dissipation aluminum plate. A pressing structure for the heat dissipation aluminum plate is connected to the frame body 1.
[0017] The curvature of the heat dissipation aluminum plate is detected by using a detection cavity 2 with the same width as the heat dissipation aluminum plate. The heat dissipation aluminum plate is placed in the middle of the detection cavity 2. By driving the screw rod 4 to rotate, during the rotation of the screw rod 4, due to the limitation of the sliding block 5 by the linear guiding structure, the rotation of the screw rod 4 can drive the sliding block 5 to move along the axial direction of the screw rod 4; since the thread directions at both ends of the screw rod 4 are opposite, the two limiting plates 7 move relatively synchronously, and the two limiting plates 7 clamp the heat dissipation aluminum plate, clamping the heat dissipation aluminum plate in the middle of the detection cavity 2. Then, the middle part of the heat dissipation aluminum plate is pressed down through the pressing structure, so that the middle part of the heat dissipation aluminum plate fits with the inner bottom of the detection cavity. After that, the curvature of the heat dissipation aluminum plate is measured by using the scale line 12 on the side wall of the detection cavity 2.
[0018] As shown in Figure 1 the figure. A mounting sleeve 3 is fixedly connected to the middle of the frame body 1. The middle of the lead screw 4 is rotatably connected to the mounting sleeve 3. A connecting frame 6 is connected to the sliding block 5 and the limiting plate 7 is connected through the connecting frame 6. The linear guiding structure is a linear groove opened on the side wall of the frame body 1, and the connecting frame 6 is located in the linear groove.
[0019] An installation groove is provided in the middle of the frame body 1, and the mounting sleeve 3 is fixedly installed in the installation groove. The lead screw 4 is horizontally rotatably connected in the installation groove through the mounting sleeve 3. Linear grooves are opened on both sides of the installation groove. The connecting frame 6 passes through the linear grooves for guiding the sliding block 5, and drives the limiting plate 7 to move through the connecting frame 6 when the sliding block 5 moves along the axial direction of the lead screw 4.
[0020] As shown in Figure 1 the figure. A connecting head is provided on the side wall of the connecting frame 6, and the connecting heads are arranged at equal intervals along the axial direction of the connecting frame 6. By providing a plurality of connecting heads on the connecting frame 6, the stable installation of the limiting plate 7 is ensured.
[0021] As shown in Figure 1 the figure. Detection cavities 2 are provided on both inner sides of the frame body 1. The lead screw 4 is located between the two detection cavities 2. Limiting plates 7 are connected to the opposite side walls of the sliding block 5. There are two pieces in a set of heat dissipation aluminum plates. By providing two detection cavities 2 in the frame body 1, the two heat dissipation aluminum plates are detected simultaneously. The two limiting plates 7 on one sliding block 5 move simultaneously, and it can be detected whether the lengths of the two heat dissipation aluminum plates are equal. Subsequently, the surface curvature of the heat dissipation aluminum plates is measured.
[0022] As shown in Figure 2 the figure. Continuous scale lines 12 are provided on the inner side wall of the detection cavity 2 along the height direction. The surface curvature of the heat dissipation aluminum plate is judged according to the intersection point of the top edge of the heat dissipation aluminum plate and the scale line 12. The scale lines 12 are equally spaced, and can be measured in the horizontal direction, and the height can also be measured according to the span of the scale lines 12.
[0023] As shown in Figure 1 and Figure 3 the figure. The pressing structure includes a support shaft 9 vertically connected to the side wall of the frame body 1, a connecting rod 10 vertically rotatably connected to the top of the support shaft 9, and a pressing rod 11 threadedly connected to the movable end of the connecting rod 10. The pressing rod 11 is vertically arranged, and the bottom end of the pressing rod 11 is hemispherical. When placing the heat dissipation aluminum plate, the connecting rod 10 is rotated to the outside of the frame body 1. After the heat dissipation aluminum plate is placed, the connecting rod 10 is rotated to directly above the heat dissipation aluminum plate, and then the pressing rod 11 is rotated to make the pressing rod 11 move downward, and the middle part of the sunken heat dissipation aluminum plate is pressed tightly in the detection cavity 2 through the bottom end of the pressing rod 11.
