[0039] like Figure 2 and Figure 5 as well as Figure 6As shown, the observation device 5 includes a support frame 501, the support frame 501 is fixedly connected to the operating table 2, the surface of the support frame 501 is fixedly connected to a fixing plate 502, the surface of the fixing plate 502 is fixedly connected to a servo motor 503, the output end of the servo motor 503 is fixedly connected to a screw rod 504, the screw rod 504 is rotatably connected to the support frame 501, the surface of the screw 504 is threadedly connected to a screw block 505, the surface of the screw block 505 is fixedly connected to an adjusting rod 506, the surface of the adjusting rod 506 is fixedly connected to a hydraulic rod 507, one end of the hydraulic rod 507 is fixedly connected to Magnifying glass 508, the surface of the support frame 501 is fixedly connected to a limit rod 509, the limit rod 509 is slidably connected to the adjusting rod 506, the screw block 505 will drive the adjusting rod 506 to move along the arc surface of the limit rod 509, at this time the limit rod 509 can limit the adjusting rod 506, the arc surface of the servo motor 503 is covered with a fixed sleeve 510, the fixed sleeve 510 is fixedly connected to the fixed plate 502, start the servo motor 503, at this time the arc surface of the servo motor 503 is covered with the fixed sleeve 510 to prevent the servo motor 503 from shaking when it is working.

[0040] The overall working principle is that when the size of the chip needs to be tested, the core 3 is first placed in the groove 402 opened on the placement plate 401, and then the turning handle 412 is pressed in the direction close to the placement plate 401. At this time, the turning handle 412 will insert the rectangular rod 411 into the screw rod 403, and at the same time, the turning handle 412 will squeeze one end of the spring 413, so that the spring 413 itself generates an outward elastic force, and then the turning handle 412 is turned, and at the same time, the turning handle 412 will drive the rectangular rod 411 to rotate, and then the rectangular rod 411 will drive the screw rod 403 to rotate. At this time, the rectangular rod 411 and the turning handle 412 can be used to To facilitate the staff to rotate the screw rod 403, the screw rod 403 will move along the surface of the placement plate 401 with the help of its own thread, and rotate along the surface of the circular plate 404, and then drive the circular plate 404 to move. At this time, the circular plate 404 will drive the push plate 405 to move, and at the same time, the push plate 405 will drive one end of the telescopic rod 409 to move. At this time, the telescopic rod 409 can prevent the push plate 405 from rotating with the rotation of the screw rod 403. Then the push plate 405 will drive the protective plate 407 to move. At this time, the protective plate 407 made of rubber material can protect the core 3 to a certain extent. , and then the core 3 will be pushed to the arc surface of the arc plate 408 by the push plate 405. At this time, the arc plate 408 can protect the corners of the core 3. When the core 3 is in close contact with the arc plate 408, the turning handle 412 is released, and then the spring 413 will use its own elastic force to push the rectangular rod 411 on the turning handle 412 out of the screw rod 403. When the turning handle 412 is rotated by external force, it will drive the connecting plate 410 and the spring 413 to rotate. At this time, the connecting plate 410 and the spring 413 can make the turning handle 412 idle, so as to avoid the turning handle 412 being accidentally touched when measuring the size of the core 3, resulting in measurement errors. If an error occurs, the size of the core 3 can be measured by observing the scale plate 406 on the placement plate 401 to test the standard size of the core 3. By setting the measuring device 4, the placement plate 401, the groove 402, the screw 403, the circular plate 404, the push plate 405 and the scale plate 406 can be used to measure according to different sizes of the core 3, thereby avoiding the situation in which the core 3 is in a more complex environment during production, and the size of the core 3 itself has errors, resulting in substandard production of the core 3 and unnecessary losses, thereby improving the efficiency of the core 3 size detection and further improving the efficiency of the core 3 production.

[0041] When it is necessary to inspect the surface of the core 3, the servo motor 503 can be started. At this time, the fixed sleeve 510 on the arc surface of the servo motor 503 can prevent the servo motor 503 from shaking when it is working. Then the output end of the servo motor 503 will drive the screw rod 504 to rotate along the surface of the support frame 501. At this time, the screw rod 504 will use its own thread to drive the screw block 505 to move, and then the screw block 505 will drive the adjusting rod 506 to move along the arc surface of the limiting rod 509. At this time, the limiting rod 509 can limit the adjusting rod 506. Then the hydraulic rod 507 is started. At this time, one side of the hydraulic rod 507 The end will drive the magnifying glass 508 to move, and then the electric melting on the surface of the core 3 is observed by moving the magnifying glass 508 to determine the defects of the electric melting on the surface of the core 3. By setting the observation device 5, the cooperation between the support frame 501, the fixing plate 502, the servo motor 503, the screw 504, the screw block 505, the adjusting rod 506, the hydraulic rod 507 and the magnifying glass 508 can be used to observe the defects of the electric melting on the surface of the core 3, thereby avoiding the problem that it is difficult for the staff to find defects when the electric melting on the core 3 itself is small, thereby improving the convenience of observing the electric melting on the surface of the core 3 and further improving the detection efficiency of the core 3.
