[0024] like Figures 1 to 4As shown, a millimeter wave antenna fixing bracket 8 includes a mounting frame 1, two electric turntables 2 are installed inside the mounting frame 1, a column 3 is installed on the top of each electric turntable 2, a lower positioning block 4 and an upper positioning block 6 are arranged vertically above the column 3, a plurality of electric telescopic columns 7 are installed on the top of the lower positioning block 4 and the bottom of the upper positioning block 6, a disassembly and assembly portion 5 for connecting the lower positioning block 4 is arranged on the column 3, the lower positioning block 4 and the upper positioning block 6 are both slidably connected with a bracket 8, a limiting portion 9 for driving the millimeter wave antenna to move is arranged on the bracket 8, the outer wall surface of the bracket 8 is threadedly connected with a telescopic rod 10, the movable end of the telescopic rod 10 is slidably connected to the inner wall surface of the mounting frame 1, and the lower positioning block 4 and the upper positioning block 6 are both elliptical;

[0025] Specifically, the provided bracket 8 can clamp and fix the millimeter-wave antenna on the surface to be inspected, eliminating the trouble of manually holding the millimeter-wave antenna and moving it to the infrared scanning probe for inspection, reducing the workload and arm pain of workers, and at the same time improving the inspection efficiency and the stability of the millimeter-wave antenna during inspection, thereby avoiding the omission of a certain surface inspection due to jitter during millimeter-wave antenna inspection, and ensuring the accuracy of product inspection and the product yield; by driving the electric turntable 2, the lower positioning block 4 can be driven to rotate, thereby pulling the millimeter-wave antenna to move horizontally, so that the outer surface of the millimeter-wave antenna can be detected, and it is also convenient to adjust the distance between the two left and right opposite brackets 8 according to the size of the millimeter-wave antenna; the provided telescopic rod 10 can ensure that the bracket 8 can always maintain the direction of horizontal movement, avoiding the deviation of the moving direction of the bracket 8.

[0026] like Figure 3 As shown, the limiting part 9 includes two clamping rollers 902, the inner wall surface of the bracket 8 is rotatably mounted with two clamping rollers 902, the inner wall surface of the bracket 8 is welded with a side plate 901 for supporting the clamping rollers 902, a clamping plate 903 is arranged between the two clamping rollers 902, and a hydraulic cylinder 904 for moving the clamping plate 903 is arranged inside the bracket 8, and the outer wall surface of the clamping roller 902 is higher than the upper surface of the bracket 8;

[0027] Specifically, the millimeter wave antenna can be clamped and fixed by the provided clamping roller 902. At the same time, with the cooperation of the clamping plate 903 installed on the other side bracket 8 in the horizontal direction, when the electric turntable 2 rotates, the clamped millimeter wave antenna can be driven to move horizontally, so that all horizontal surfaces of the millimeter wave antenna can be moved within the detectable range of the infrared scanning probe to avoid detection omissions.

[0028] like Figure 4As shown, the disassembly and assembly part 5 includes an installation cavity 509, and the top of the column 3 is provided with an installation cavity 509, and four sliders 502 are slidably connected to the inner wall surface of the installation cavity 509, and the inner wall surfaces of the four sliders 502 are fixedly provided with installation tubes 501 connected to the top and the bottom of the lower positioning block 4, and the outer wall surfaces of the sliders 502 are bonded with sealing rubber pads;

[0029] Specifically, by vertically inserting the installation tube 501 downward into the installation cavity 509 , the lower positioning block 4 can be installed and fixed, and the slider 502 provided at the same time can enhance the stability of the installation tube 501 inserted into the installation cavity 509 .

[0030] like Figure 4 As shown, a bidirectional screw 507 is rotatably installed on the inner wall of the installation cavity 509, and two fixing rings 508 are mirror-imaged on the outer wall of the bidirectional screw 507. A positioning plate 504 is fixedly connected to the outer wall of the fixing ring 508. The two positioning plates 504 are threadedly connected to the wall on one side away from each other with a support rod 505. A limiting hole 506 for inserting the support rod 505 is opened on the inner wall of the installation tube 501. The outer wall of the limiting hole 506 is slidably connected to the inner wall of the installation cavity 509, and a sealing rubber pad is bonded to the outer wall of the support rod 505.

[0031] In order to facilitate the disassembly and replacement of the support rod 505, the connection between the positioning plate 504 and the support rod 505 is a threaded connection;

[0032] In order to facilitate the rotation of the bidirectional screw 507, a motor 11 for driving the bidirectional screw 507 is installed on the outer wall surface of the column 3;

[0033] Specifically, by rotating the bidirectional screw 507, the two positioning plates 504 can be driven to move closer to or farther from each other, so that multiple support rods 505 can be plugged into the inside of the limiting hole 506, thereby improving the stability of the installation tube 501 installed in the installation cavity 509 and enhancing the stability and stability of the bottom of the lower positioning block 4 when in use.

[0034] When in use, the staff can move the mounting frame 1 to one side of the infrared scanning probe, and then place the millimeter-wave antenna of the outer surface to be detected between the two columns 3. Driving the electric turntable 2 can drive the column 3 to rotate, thereby changing the distance between the left and right brackets 8, so that when the bracket 8 is moved above the millimeter-wave antenna, the electric telescopic column 7 is driven to drive the upper positioning block 6 to move downward until the upper and lower corresponding clamping rollers 902 can clamp and fix the millimeter-wave antenna. At this time, the two ends of the millimeter-wave antenna are located on the outside of the bracket 8, that is, its two ends are close to the electric telescopic column 7 and do not contact the electric telescopic column 7 (in actual use, the electric telescopic bracket 8 can be installed at the bottom of the mounting frame 1, so that the horizontal center axis of the clamped millimeter-wave antenna to be detected can be opposite to the center line of the detectable range of the infrared scanning probe), and then the left side is driven. The two hydraulic cylinders 904 on the two brackets 8 can enable the upper and lower clamping plates 903 to clamp the millimeter wave antenna. At this time, driving the electric turntable 2 under the hydraulic cylinder 904 can drive the column 3 to rotate. Under the pulling action of the clamping plate 903 and the rotation action of the two clamping rollers 902 clamping the other end of the millimeter wave antenna, the millimeter wave antenna can be driven to move horizontally. After the left column 3 rotates 360 degrees, the above steps are repeated in reverse, that is, the right clamping plate 903 is driven to clamp one end of the millimeter wave antenna, so that the other end of the millimeter wave antenna is clamped by the clamping roller 902 on the left, and the right electric turntable 2 is driven to drive the column 3 to rotate 360 ​​degrees, so as to avoid missing detection on the outer surface of the millimeter wave antenna. When the other side needs to be detected, it is only necessary to drive the electric telescopic column 7 to adjust the direction of the millimeter wave antenna and then re-fix it.

[0035] In summary: the bracket 8 is set up to clamp and fix the millimeter-wave antenna on the surface to be inspected, eliminating the trouble of manually holding the millimeter-wave antenna and moving it to the infrared scanning probe for inspection, reducing the workload and arm pain of workers, and at the same time improving the inspection efficiency and the stability of the millimeter-wave antenna during inspection, and avoiding the omission of a certain surface inspection due to jitter during millimeter-wave antenna inspection, thereby ensuring the accuracy of product inspection and the product yield; by driving the electric turntable 2, the lower positioning block 4 can be driven to rotate, thereby pulling the millimeter-wave antenna to move horizontally, so that the outer surface of the millimeter-wave antenna can be detected; the telescopic rod 10 is set up to ensure that the bracket 8 can always maintain the direction of horizontal movement, avoiding the deviation of the moving direction of the bracket 8.
