This allows the device to change the initial height of multiple sets of detection probes according to different detection positions during testing. By screwing in or out the screws, the initial position of the movable blocks can be changed. When the extension plate abuts against the movable block, the movable block will pull the support plate at that position downwards through the traction steel rope. This allows the microcontroller on the device to perform defect detection work through detection probes of different heights and positions when it moves to different positions. In this way, the device can adaptively adjust the detection path, solving the problem that existing microcontroller defect detection devices cannot adaptively adjust the detection path trajectory according to different types of microcontrollers.

When the first electric push rod is shortened, it abuts the first connecting plate against the slide rod, preventing the slide rod from driving the slide plate and slide seat to slide on the base plate. At this time, the device uses a fixed detection method. When the first electric push rod on the switching component is extended, refer to... Figure 2 and Figure 6 By placing a mounting block in the mounting slot, the partition and extension plate are fixed as a whole. Then, the screw is screwed in, causing the movable block to move outward of the slide. When the extension plate abuts against the movable block, it will first drive the slide as a whole to slide on the base plate, thus realizing the function of follow-up detection. When the pressure on the movable block is large enough, the movable block will retract into the device for the next use. This device solves the defect of existing single-chip microcomputer defect detection devices that cannot switch between follow-up detection and fixed detection. This device has the advantage of being more adaptable. Attached Figure Description

[0051] Specifically, the present application is a single-chip microcomputer processing defect detection device and method with a positioning mechanism, first, Figures 1-9As shown, the single-chip microcomputer is placed between two adjacent partitions 17 on the conveying belt 2 and abuts against the same position on the partition 17 or the same position between two adjacent partitions 17 to ensure the accuracy of subsequent detection. The single-chip microcomputer is continuously conveyed by the conveying belt 2. In the conveying process, the extension plate 22 on the partition 17 abuts against the inclined surface of the movable block 10 in the inner groove 13, thereby compressing the movable block 10 into the inner groove 13 in the sliding seat 4. At this time, the third spring 11 on the adjusting plate 29 is compressed, and at the same time, the protruding rod 9 in the second groove 28 pulls the corresponding position of the supporting plate 7 through the traction steel rope 8, so that the supporting plate 7 moves downward, and the corresponding position of the single-chip microcomputer is detected by the detection probe 16. When the detection track needs to be changed, the initial height of each detection probe 16 on each supporting plate 7 is adjusted by the adjusting assembly 14. The protruding ring 1404 and the sliding block 1401 can change the initial position of themselves in the sliding groove 1402 and the extension groove 1403 on the supporting plate 7, thereby changing the detection position. The protruding block 1405 is fixedly arranged on the protruding ring 1404, the screw column 15 and the sliding block 1401 are threadedly connected, the height of each detection probe 16 is changed by screwing in or out of the screw column 15, thereby changing the detection height of different detection areas on the supporting plate 7 to adapt to different single-chip microcomputers for use.

[0052] As shown in Figure 7 and Figure 8 , the device can change the initial position of the adjusting plate 29 by screwing in or out of the screw rod 12, thereby changing the extension length of the movable block 10 on the sliding seat 4. When the extension plate 22 abuts against the inclined surface of the movable block 10, the initial height of each detection probe 16 is different, and the detection probe 16 on the supporting plate 7 at different positions moves downward by different distances, thereby detecting different positions of the single-chip microcomputer. As shown in Figure 4 , since the positions and quantities of the supporting assemblies 6 and the positions and quantities of the movable blocks 10 are one-to-one corresponding, the device can change the initial position of the movable rod 602 in the outer cylinder 603 by elongating or shortening the second electric push rod 601 when in use, thereby changing the initial position of the first connecting rod 605 and the supporting plate 7, facilitating subsequent switching of the detection track of the device. As shown in Figures 7-12 , the device can be switched between follow-up detection and fixed detection. The initial position of the first connecting plate 502 is changed by elongating or shortening the first electric push rod 501. After the first electric push rod 501 is shortened, the sliding plate 3 cannot be slid until the first connecting plate 502 abuts against the sliding rod 505. At this time, the fixed detection can be used. After the first electric push rod 501 is elongated, the sliding plate 3 can slide when the first connecting plate 502 is in Figure 6When the state in the middle, the device can be switched to follow the detection. By installing the block 26 into the installation slot 25, the fixed shaft 24 and the first connecting ring 20 are clamped, at this time the extension plate 22 will not rotate in the partition 17, by the screw 12 is screwed into the slide 4 in the appropriate position, when the extension plate 22 and the movable block 10 abutment will drive the slide 4 on the whole slide on the base plate 1, so as to follow the detection, with the pressure of the movable block 10 gradually increases, the movable block 10 will be compressed to the inside of the slide 4, at this time the slide 4 can be automatically reset through the first spring 504 on the switching assembly 5 in order to use next time.

[0053] The above only for the preferred embodiments of the present application, and not to limit the present application, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the scope of protection of the present application.
