[0028] The lifting mechanism 6 comprises a lifting lead screw 601, a servo motor 602 and a lifting block 603. The lifting lead screw 601 is vertically installed beside the first guide rod 8 and parallel to the first guide rod 8. The surfaces of two ends of the lifting lead screw 601 are rotatably connected with the top and bottom surfaces of the support 2 respectively. The servo motor 602 is detachably installed on the top surface of the support 2. The output end of the servo motor 602 is connected with the top end of the lifting lead screw 601. The servo motor 602 is a forward and reverse motor, which belongs to the prior art.
[0029] The lifting block 603 is provided with a first screw hole 604 and a first guide hole 605 at intervals, the first screw hole 604 and the first guide hole 605 are vertical through holes, the first guide rod 8 passes through the first guide hole 605 and is in sliding connection with the lifting block 603, and the lifting lead screw 601 passes through the first screw hole 604 and is in threaded connection with the lifting block 603.

[0030] The lifting block 603 is provided with a first screw hole 604 and a first guide hole 605 at intervals, the first screw hole 604 and the first guide hole 605 are vertical through holes, the first guide rod 8 passes through the first guide hole 605 and is in sliding connection with the lifting block 603, and the lifting lead screw 601 passes through the first screw hole 604 and is in threaded connection with the lifting block 603. In this way, the servo motor 602 can drive the lifting lead screw 601 to rotate when the servo motor 602 operates, the lifting lead screw 601 further drives the lifting block 603 to move in the vertical direction, and the lifting block 603 can accurately adjust the lifting position under the control of the threads of the lifting lead screw 601; meanwhile, the lifting block 603 slides along the first guide rod 8, the first guide rod 8 plays a guiding role on the lifting block 603, so that the movement of the lifting block 603 in the vertical direction is more stable, and the balance of the lifting block 603 is improved.
[0031] The positioning mechanism 7 comprises a placing plate 701 used for placing a workpiece to be detected. The placing plate 701 is in sliding connection with the second guide rod 608. Specifically, the placing plate 701 is provided with a second guide hole 702 penetrating in the horizontal direction, and the second guide rod 608 passes through the second guide hole 702, so that the placing plate 701 can slide horizontally along the second guide rod 608.
[0032] The bottom of the placing plate 701 is provided with a connecting pipe 703, and the inside of the connecting pipe 703 has a second screw hole 704. Specifically, the connecting pipe 703 is a tubular body with the second screw hole 704 in the inside, and the connecting pipe 703 is integrally formed at the bottom of the placing plate 701. The adjusting lead screw 607 extends into the second screw hole 704 and is in threaded connection with the connecting pipe 703. In this way, when the adjusting motor 606 operates, the adjusting motor 606 drives the adjusting lead screw 607 to rotate, and the adjusting lead screw 607 drives the placing plate 701 to move in the horizontal direction. The adjusting lead screw 607 can accurately control the horizontal movement position of the placing plate 701 through threads, so as to adjust the distance between the workpiece to be detected and the second ultrasonic thickness gauge probe 4; meanwhile, the placing plate 701 slides horizontally along the second guide rod 608, and the second guide rod 608 plays a guiding role on the placing plate 701, so that the movement of the placing plate 701 in the horizontal direction is more stable.
[0033] The surface of the placing plate 701 is rotationally connected with a rotating plate 707, which is used to place the workpiece to be detected and has a rotating function, so as to realize the side surface change of the workpiece to be detected and facilitate the detection of the conductive layer on different sides of the workpiece to be detected by the second ultrasonic thickness gauge probe 4.
[0034] With reference to Figure 4 and Figure 5 , a rotating groove 706 is formed in the middle position of the placing plate 701, and a rotating block 708 is fixedly connected to the bottom of the rotating plate 707 and rotatably embedded in the rotating groove 706, that is, the inner wall of the rotating groove 706 is rotationally connected with the surface of the rotating block 708, so that the placing plate 701 can freely rotate under the action of an external force, and the rapid side surface change detection of the workpiece to be detected can be facilitated. When the side surface change detection of the workpiece to be detected is needed, the outer edge of the rotating plate 707 is held and rotated by a predetermined angle.
[0035] The rotating groove 706 and the rotating block 708 are both T-shaped, which ensures the safety of the connection between the rotating plate 707 and the placing plate 701, and the frictional resistance between the rotating block 708 and the rotating groove 706 is large, so that the rotating plate 707 cannot be automatically rotated at will and affect the detection process.
[0036] The surface of the rotating plate 707 is also provided with anti-skid lines, which can increase the friction between the workpiece to be detected placed on the surface of the rotating plate 707 and the rotating plate 707, so that the workpiece to be detected is stably placed and is not easy to slide off.
[0037] With reference to Figure 3 and Figure 4 , a vertical through strip-shaped channel 705 is formed in the surface of the placing plate 701, and the strip-shaped channel 705 penetrates the placing plate 701 in the vertical direction. The center line of the strip-shaped channel 705 is in the same plane as the center line of the first ultrasonic thickness gauge probe 3. In this way, when the size of the workpiece is small, the ultrasonic waves of the first ultrasonic thickness gauge probe 3 can pass through the strip-shaped channel 705 and reach the bottom surface of the workpiece to be detected to detect the thickness of the conductive layer.
[0038] With reference to Figure 3 and Figure 4 Figure 3 Figure 4 , the placing plate 701 is provided with two second guide holes 702 at intervals, the number of the second guide rods 608 is two and they are arranged at intervals, and the two second guide rods 608 respectively pass through the two second guide holes 702 correspondingly, so that the second guide rods 608 and the placing plate 701 are slidingly connected. The height of the second guide hole 702 is higher than that of the second screw hole 704. In this way, the two second guide holes 702 and the second screw hole 704 are distributed in a triangular shape, which can increase the moving stability of the placing plate 701 and avoid the falling of the placed workpiece to be detected due to movement.
