The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0032] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0033] In one embodiment of the present invention, according to Figure 1-3As shown, a high-efficiency heat dissipation image measuring instrument includes a base 100; a stage 110 is provided on the base 100, and the stage 110 is used to place the workpiece to be measured; a camera device 200, which is connected to the base 100 through a connecting column 300 and is suspended above the stage 110; a moving device is provided between the stage 110 and the base 100, and the moving device is used to move the stage 110 forward, backward, left and right; the camera device 200 includes a housing 210 and a lifting assembly 22 provided inside the housing 210 0 and camera 230; the camera 230 is connected to the connecting column 300 through the lifting assembly 220, the camera 230 is suspended above the stage 110, and a heat dissipation assembly is provided on the camera 230, which is used to dissipate heat for the camera 230. A cavity 310 is provided in the connecting column 300, and the cavity 310 is connected to the interior of the shell 210. An air supply device 320 is provided in the cavity 310, and a heat dissipation hole 211 is provided on the shell 210. The air supply device 320 can blow air into the interior of the shell 210 and blow it out from the heat dissipation hole 211.

[0034] Specifically, by providing a heat dissipation assembly, the heat inside the camera 230 can be effectively controlled and dissipated, thereby preventing the camera 230 from operating for a long time and damaging the internal components due to overheating. By providing an air supply device 320 to blow air into the housing 210, the heat dissipated by the heat dissipation assembly can be effectively blown out through the heat dissipation holes 211, thereby improving the heat dissipation effect.

[0035] In another embodiment of the present invention, according to Figure 1 As shown, the heat dissipation assembly includes a heat sink 241, which is connected to the lifting assembly 220. The heat sink 241 is provided with a mounting position 242, and the camera 230 is mounted on the mounting position 242. Heat from the camera 230 is transferred to the heat sink 241 for dissipation. The heat dissipation assembly also includes a heat dissipation circulation assembly, which includes an inlet pipe 243, an outlet pipe 244, and a liquid pump 245 connected to the inlet pipe 243 and the outlet pipe 244. A circulation chamber is provided within the heat sink 241, and one end of the inlet pipe 243 and the outlet pipe 244 are connected to the circulation chamber. The heat sink 241 is also provided with a temperature sensor 246, which is electrically connected to the liquid pump 245. Heat dissipation fins 247 are provided on the heat sink 241.

[0036] Specifically, the heat sink 241 is provided with heat sink fins 247, which can increase the heat dissipation area and dissipate the heat on the heat sink 241 into the air. At the same time, an active heat dissipation system is also provided, and the circulation cavity is filled with heat dissipation liquid, such as water, thermal oil, etc., which can circulate between the circulation cavity and the water inlet pipe 243 and the water outlet pipe 244.

[0037] It is understood that the liquid pump 245 can be turned on or off. When the temperature of the heat sink 241 is too high, the liquid pump 245 can be turned on to increase the heat dissipation efficiency, allowing the heat dissipation liquid to flow completely. The flowing heat dissipation liquid can continuously remove the heat transferred from the heat dissipation unit to the heat sink 241, preventing the temperature in the local area from rising. Static liquid easily forms a temperature gradient, and its overall heat exchange capacity is inferior to that of flowing liquid. It can be seen that turning on the liquid pump 245 has a better heat dissipation effect and higher heat dissipation efficiency. It is understood that the temperature sensor 246 can also be electrically connected to the air supply device 320. When the temperature is too high, the air supply device 320 is also turned on to increase the heat dissipation efficiency.

[0038] In another embodiment of the present invention, according to Figure 1 As shown, the lifting assembly 220 includes a screw assembly 221; the screw assembly 221 is arranged on the connecting column 300, a slider 222 is provided on the screw assembly 221, the heat dissipation plate 241 is connected to the slider 222, and a bevel gear set 223 is provided at the bottom of the screw assembly 221, one end of the bevel gear set 223 is connected to the screw assembly 221, and the other end is connected to an adjusting wheel 224, and the adjusting wheel 224 can adjust the bevel gear set 223, thereby adjusting the screw assembly 221 to control the up and down movement of the camera 230.

[0039] The adjusting wheel 224 includes a transmission shaft; a fixing block 225 is provided on the connecting column 300, and a transmission hole is provided on the fixing block 225. The transmission shaft passes through the transmission hole and is connected to the bevel gear set 223.

[0040] The bevel gear set 223 includes a first bevel gear 2231 and a second bevel gear 2232 meshing with each other; the first bevel gear 2231 is connected to the screw assembly 221, and the second bevel gear 2232 is connected to the transmission shaft.

[0041] Specifically, the adjusting wheel 224 is rotated, and the transmission shaft rotates accordingly, driving the second bevel gear 2232 to rotate, further driving the first bevel gear 2231 to rotate, thereby driving the screw assembly 221 to move, and finally driving the camera 230 to move up and down.

[0042] Furthermore, by lifting the camera 230 , a suitable measurement position can be found according to the size of the workpiece, thereby achieving adaptability and accuracy requirements.

[0043] In another embodiment of the present invention, according to Figure 3 As shown, the moving device includes an X-axis moving assembly 410 and a Y-axis moving assembly 420; the Y-axis moving assembly 420 is disposed on the base 100, and the X-axis moving assembly 410 is disposed on the Y-axis moving assembly 420. Specifically, the X-axis moving assembly 410 and the Y-axis moving assembly 420 can drive the stage 110 to move forward, backward, left, and right.

[0044] In another embodiment of the present invention, according to Figure 3 As shown, an electrostatic dust removal box 500 is provided on the base 100, and the electrostatic dust removal box 500 is used to absorb dust.
