Technical Field

[0002] As the degree of chip integration becomes higher and higher, the uneven power distribution inside the chip becomes more and more obvious, resulting in the appearance of "hot spots" on the microscale inside the chip. The appearance of hot spots causes the local temperature of the chip to increase, affecting the service life of the chip. When exploring the hot spots of the chip, an infrared imager is used to determine the location of the chip hot spots. After searching, the prior art (application number: CN202320620127.8) records that "when the device is used as a whole, the infrared imager body and the auxiliary frame are flipped, so that the lens of the infrared imager body is turned to one side of the handlebar, and the lens is fixed and covered by the rotation of the positioning ring, so as to protect and isolate the lens, so that the whole will not be scratched or bumped with other external objects when carried, and a certain isolation and anti-interference effect is achieved, thereby extending the service life of the whole, and the overall protection effect is good. At the same time, the positioning of the lens by the positioning ring during use can also ensure the stability of the infrared imager body after rotation and folding, and the overall use effect is good." However, the movable infrared imager lens in the prior art has a problem that the chip volume is small, and the shaking of the lens during detection will cause deviation in the chip hot spot detection position.

[0005] A fixing plate is welded to the rear end of the infrared imager, an adjusting screw is installed on the front surface of the fixing plate, the adjusting screw is connected to a connecting plate through a nut block, the front end of the connecting plate is connected to a support rod through an electric push rod, an infrared positioning ring is welded to the front end of the support rod, the groove wall at the upper end of the detection base is connected to a splint through a screw nut mechanism, and a transmission column head is connected to the left end of the screw nut mechanism.

[0006] Furthermore, a chip detection platform is welded on the upper surface of the detection machine base, and clamping plates are symmetrically distributed in the left and right side grooves of the chip detection platform.

[0007] Furthermore, the screw nut mechanism is composed of two screw nuts; and one ends of the two screw nuts are butted against each other, and the lower end of the clamping plate is connected to the nut on the surface of the screw.

[0008] Furthermore, a hydraulic rod is embedded and installed on the rear side of the fixing plate; and a sleeve is connected to the front end of the hydraulic rod, and a display screen is arranged on the upper surface of the infrared imager.

[0010] Furthermore, the infrared positioning ring is located below the infrared imager; and a ring-shaped infrared lamp is embedded and installed on the lower surface of the infrared positioning ring.

[0011] Furthermore, the infrared positioning ring, the adjusting screw, the connecting plate, the supporting rod and the electric push rod constitute a positioning machine structure for detecting images of the infrared imager.

[0012] The beneficial effect of the utility model is that the chip hotspot detection infrared imager of the utility model utilizes an adjusting screw and an electric push rod to adjust the position of the infrared positioning circle horizontally and vertically, so that the infrared positioning circle is moved to a position above the hotspot position of the infrared imager detection screen, and the detection position of the chip hotspot is located by infrared rays projected downward by the infrared positioning circle, thereby realizing an infrared imager with a detection and positioning function, which is convenient for workers to directly and clearly determine the hotspot position of the chip, saves the operation time of searching for the hotspot position on the infrared imager display screen each time, and speeds up the work efficiency of subsequent exploration of the chip hotspot.
