[0016] A defect detection method for single-chip microcomputer processing with a positioning mechanism comprises the following steps:

[0017] S1: Place the single-chip microcomputer between two adjacent partitions on the conveyor belt, and continuously convey the single-chip microcomputer through the conveyor belt. During the conveying process, the extension plate on the partition will abut against the inclined surface of the movable block, compressing the movable block into the interior of the slide seat. At this time, the third spring on the adjustment plate is compressed, and the convex rod pulls the support plate at the corresponding position through the traction steel rope, so that the support plate moves downward, and the corresponding position of the single-chip microcomputer is detected by the detection probe;

[0018] S2: When the detection track needs to be changed, the initial height of each detection probe on each support plate is adjusted through the adjustment component, and the initial position of the adjustment plate is changed by screwing in or out the screw, thereby changing the extension length of the movable block on the slide. When the extension plate abuts against the inclined surface of the movable block, the initial height of each detection probe is different, and the detection probes on the support plates at different positions move downward by different distances, thereby detecting different positions of the single-chip computer;

[0019] S3: When the device performs follow-up detection, the sliding plate can slide on the bottom plate through the switching component, and the mounting block is installed into the mounting groove to complete the engagement of the fixed shaft and the first connecting ring. At this time, the extension plate will not rotate on the partition. By screwing the screw into the appropriate position in the slide, when the extension plate abuts against the movable block, it will drive the slide as a whole to slide on the bottom plate, thereby performing follow-up detection. As the pressure of the movable block gradually increases, the movable block will be compressed into the interior of the slide. At this time, the slide can be automatically reset by the switching component.

[0020] The working principle and beneficial effects of the present invention are:

[0021] 1. The device is provided with a supporting assembly and an adjusting assembly. The supporting assembly is used to change the initial height of the supporting plate, the adjusting assembly is used to change the initial positions of multiple detection probes on the supporting plate, and the studs are used to change the initial height of the detection probes, thereby adapting to different undulations on the single-chip microcomputer and adaptively adjusting the detection height, thereby enhancing the application scope of the device and solving the problem that the existing single-chip microcomputer defect detection device cannot adaptively adjust the height of the detection probe according to the undulation of the single-chip microcomputer surface.

[0022] 2. The number of support components on the device corresponds to the position and number of movable blocks. When detecting, the device can change the initial heights of multiple groups of detection probes according to different detection positions, and change the initial position of the movable block by screwing in or out the screw. When the extension plate abuts the movable block, the movable block will pull the support plate at that position downward through the traction steel rope, so that when the single-chip microcomputer on the device moves to different positions, the single-chip microcomputer can be detected for defects through detection probes at different heights and positions, thereby enabling the device to adaptively adjust the detection path, solving the problem that the existing single-chip microcomputer defect detection device cannot adaptively adjust the trajectory of the detection path according to different types of single-chip microcomputers.

[0023] 3. The device is provided with a switching assembly. When the first electric push rod is shortened, the first connecting plate is abutted against the slide rod, so that the slide rod cannot drive the slide plate and the slide seat to slide on the bottom plate. At this time, the device adopts a fixed detection. When the first electric push rod on the switching assembly is extended, you can refer to Figure 2 and Figure 6 By placing the mounting block in the mounting groove, the partition and the extension plate are fixed as a whole. At this time, the screw is screwed in to move the movable block to the outside 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 bottom plate, thereby realizing the function of follow-up detection. When the pressure on the movable block is large enough, the movable block will shrink into the inside of the device for the next use. This device solves the defect that the existing single-chip microcomputer defect detection device cannot switch between follow-up detection and fixed detection. The device has the advantage of greater adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

The partitions 17 are used to separate multiple single-chip microcomputers for subsequent individual detection. A first connecting ring 20 is fixedly connected to the partition 17, and a fixed shaft 24 is rotatably installed in the first connecting ring 20. A second connecting ring 21 is fixedly connected below the fixed shaft 24, and an extension plate 22 is fixedly connected below the second connecting ring 21. A vortex spring 23 is fixedly connected between the first connecting ring 20 and the fixed shaft 24. The vortex spring 23 enables the extension plate 22 to bend after being subjected to a sufficiently large pressure, so that the conveyor belt 2 can rotate normally later. The first connecting ring 20 and the fixed shaft 24 are both provided with mounting grooves 25, and a mounting block 26 is installed in the mounting groove 25. A slide plate 3 is slidably installed on the base plate 1, and a switching component 5 is installed between the base plate 1 and the slide plate 3. 5 enables the device to adjust the connection state between the slide plate 3 and the bottom plate 1. When the slide plate 3 and the bottom plate 1 are in an elastic connection state, the device can be switched to follow-up detection. The slide plate 3 is fixedly connected with a slide seat 4, and a support assembly 6 is installed on the slide seat 4. A support plate 7 is fixedly connected below the support assembly 6. An adjustment assembly 14 is installed on the support plate 7. A stud 15 is installed on the inner thread of the adjustment assembly 14. A detection probe 16 is fixedly arranged below the stud 15. The adjustment assembly 14 is used to change the initial position of the stud 15 at various locations on the support plate 7, thereby changing the initial position of the detection probe 16. A traction steel rope 8 is fixedly connected to the bottom of the support plate 7, and a convex rod 9 is fixedly connected to the traction steel rope 8.

The screw 12 can be screwed into the slide 4 to change the initial position of the movable block 10. After the initial position of the movable block 10 changes, the initial height of the support plate 7 corresponding to the movable block 10 is changed through the support assembly 6, so that after the extension plate 22 abuts against the movable block 10, the downward movement distance of the support plate 7 is changed, thereby changing the detection position of the device.

[0041] Example 2

[0042] like Figure 1-Figure 12 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a defect detection device for single chip microcomputer processing with a positioning mechanism.

[0043] In this embodiment, the switching assembly 5 includes a first electric push rod 501 fixedly connected to the base plate 1, a first connecting plate 502 is fixedly connected to the front end of the first electric push rod 501, a second connecting plate 503 is fixedly arranged on the side of the first electric push rod 501, a first spring 504 is installed between the second connecting plate 503 and the slide plate 3, and a slide bar 505 is fixedly arranged at the bottom of the slide plate 3. The device can change the initial position of the first connecting plate 502 by extending or shortening the first electric push rod 501. When the first connecting plate 502 abuts against the slide bar 505, the slide plate 3 cannot slide. At this time, a fixed detection can be adopted. When the first connecting plate 502 is in Figure 6 When in the status of , the device can switch to follow-up detection.

[0044] In this embodiment, the sliding rod 505 runs through the inside of the second connecting plate 503, the first connecting plate 502 and the second connecting plate 503 are parallel to each other, and the sliding plate 3 and the sliding seat 4 form a sliding structure with the bottom plate 1 through the sliding rod 505, the extension plate 22 and the movable block 10. Through the sliding structure on the device, when the extension plate 22 abuts against the movable block 10, the movable block 10 is pressed to drive the sliding plate 3 and the sliding seat 4 to slide as a whole on the bottom plate 1 until the movable block 10 is completely retracted into the inside of the device, thereby realizing the follow-up detection work.

[0045] In this embodiment, the support assembly 6 includes a second electric push rod 601 and an outer cylinder 603 fixedly connected to both sides of the slide seat 4, a movable rod 602 is fixedly connected to the second electric push rod 601, the bottom of the movable rod 602 is fixedly connected to a second spring 604, and the lower part of the second spring 604 is fixedly connected to a first connecting rod 605, the first connecting rod 605 and the movable rod 602 are both slidably installed in the outer cylinder 603, the first connecting rod 605 and the support plate 7 are fixedly connected, the position and number of the support assembly 6 correspond to the position and number of the movable blocks 10 in a one-to-one manner, and the device can change the initial position of the movable rod 602 in the outer cylinder 603 by extending or shortening the second electric push rod 601 when in use, thereby changing the initial position of the first connecting rod 605 and the support plate 7, so as to facilitate the detection trajectory of the subsequent switching device.

[0046] In this embodiment, a second groove 28 is provided in the movable block 10 for the traction steel rope 8 to pass through, and the protruding rod 9 is located in the second groove 28. The bottom of the movable block 10 is fixedly connected with a connecting block 18. The slide seat 4 is provided with an inner groove 13 for the movable block 10 to slide and a movable groove 19 for the connecting block 18 to slide. Beveled surfaces are provided on both sides of the movable block 10. The movable block 10 is suitable for shrinking into the slide seat 4 after abutting against the extension plate 22. The inclined surface of the movable block 10 can abut against the extension plate 22, and the extension plate 22 can continue to move while keeping the extension plate 22 without bending, so as to adaptively adjust the defect detection position later.

[0047] In this embodiment, the adjustment component 14 includes a slide groove 1402 and an extension groove 1403 opened on the support plate 7. A slider 1401 is slidably installed in the slide groove 1402. A convex ring 1404 is fixedly provided on the outer side of the slider 1401. The convex ring 1404 and the slider 1401 can change their initial positions in the slide groove 1402 and the extension groove 1403 on the support plate 7, thereby changing the detection position. A bump 1405 is fixedly provided on the convex ring 1404. The stud 15 and the slider 1401 are threadedly connected. By screwing in or out the stud 15, the detection height of different detection areas on the support plate 7 can be changed to adapt to the use of different single-chip microcomputers.

[0048] In this embodiment, the upper and lower surfaces of the convex ring 1404 are in contact with the inner wall of the extension groove 1403. The convex ring 1404 and the protrusions 1405 are both made of rubber. The protrusions 1405 are evenly distributed along the circumference of the convex ring 1404. The convex ring 1404 and the protrusions 1405 on its surface are both made of rubber. This allows the convex ring 1404 to remain fixed as an axis when it moves to the extension groove 1403, thereby ensuring the overall stability of the device.

[0049] In this embodiment, a first groove 27 is opened in the mounting block 26, and the fixed shaft 24 forms a locking structure with the first connecting ring 20 through the mounting block 26 and the mounting groove 25. The extension plate 22 forms an elastic structure with the fixed shaft 24 through the vortex spring 23. The elastic structure on the device allows the extension plate 22 to bend when it is under excessive pressure, thereby ensuring the safety of the device when in use. When the mounting block 26 is placed inside the mounting groove 25, the extension plate 22 cannot be bent, so that the entire device can be switched to follow-up detection later.

[0050] In this embodiment, the adjustment plate 29 and the movable block 10 form a telescopic structure between the screw rod 12 and the slide seat 4, and the traction steel rope 8 is suitable for pulling the support plate 7 and the detection probe 16 downward when the extension plate 22 abuts against the movable block 10, so that the device can abut the movable block 10, thereby using the traction steel rope 8 to pull the pulling support plate 7 and the detection probe 16 at the corresponding position downward, and perform targeted detection on different types of single-chip microcomputers.

[0051] Specifically, the present invention is a defect detection device and method for single chip microcomputer processing with a positioning mechanism. First, Figure 1-Figure 9As shown, the single-chip microcomputer is placed between two adjacent partitions 17 on the conveyor belt 2, and the single-chip microcomputer is abutted against the same position on the partition 17 or placed at the same position between two adjacent partitions 17 to ensure the accuracy of subsequent detection. The single-chip microcomputer is continuously transported by the conveyor belt 2. During the transportation process, the extension plate 22 on the partition 17 will abut against the inclined surface of the movable block 10 in the inner groove 13, and the movable block 10 will be compressed into the inner groove 13 in the slide seat 4. At this time, the third spring 11 on the adjustment plate 29 is compressed. At the same time, the convex rod 9 in the second groove 28 pulls the support plate 7 at the corresponding position through the traction steel rope 8, so that the support plate 7 moves downward, and the corresponding position of the single-chip microcomputer is detected by the detection probe 16. When the detection trajectory needs to be changed, the initial height of each detection probe 16 on each support plate 7 is adjusted by adjusting the adjustment component 14. The convex ring 1404 and the slider 1401 can change their initial positions in the slide groove 1402 and the extension groove 1403 on the support plate 7, thereby changing the detection position. A protrusion 1405 is fixedly provided on the convex ring 1404, and the stud 15 and the slider 1401 are threadedly connected. By screwing in or out the stud 15, the height of each detection probe 16 is changed, thereby changing the detection height of different detection areas on the support plate 7 to adapt to the use of different single-chip microcomputers.

[0052] like Figure 7 and Figure 8 As shown, the device can change the initial position of the adjustment plate 29 by screwing in or out the screw 12, thereby changing the extension length of the movable block 10 on the slide 4. When the extension plate 22 abuts against the inclined surface of the movable block 10, the initial heights of the detection probes 16 are different, and the detection probes 16 on the support plates 7 at different positions move downward by different distances, thereby detecting different positions of the single chip computer. Figure 4 As shown, since the position and number of the support assembly 6 correspond to the position and number of the movable block 10, the device can change the initial position of the movable rod 602 in the outer cylinder 603 by extending or shortening the second electric push rod 601 when in use, thereby changing the initial position of the first connecting rod 605 and the support plate 7, which is convenient for the subsequent switching of the detection track of the device. Figure 7-Figure 12 As shown, the device can switch between follow-up detection and fixed detection. By extending or shortening the first electric push rod 501, the initial position of the first connecting plate 502 is changed. After shortening the first electric push rod 501, until the first connecting plate 502 abuts against the slide bar 505, the slide plate 3 cannot slide. At this time, fixed detection can be used. After extending the first electric push rod 501, when the first connecting plate 502 is in Figure 6When the device is in the state of being in the middle, the device can be switched to the follow-up detection. By installing the mounting block 26 into the mounting groove 25, the engagement work of the fixed shaft 24 and the first connecting ring 20 is completed. At this time, the extension plate 22 will not rotate on the partition 17. By screwing the screw 12 into the appropriate position in the slide 4, when the extension plate 22 abuts against the movable block 10, it will drive the slide 4 as a whole to slide on the bottom plate 1, so as to perform the follow-up detection. As the pressure of the movable block 10 gradually increases, the movable block 10 will be compressed into the inside of the slide 4. At this time, the slide 4 can be automatically reset by the first spring 504 on the switching component 5 for the next use.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

10. A method for detecting defects in single-chip microcomputer processing with a positioning mechanism, using the single-chip microcomputer processing defect detection device with a positioning mechanism as claimed in claim 1, characterized in that: The steps include: S1: placing the single-chip microcomputer between two adjacent partitions (17) on the conveyor belt (2), and continuously conveying the single-chip microcomputer through the conveyor belt (2). During the conveying process, the extension plate (22) on the partition (17) will abut against the inclined surface of the movable block (10), compressing the movable block (10) into the interior of the slide seat (4). At this time, the third spring (11) on the adjustment plate (29) is compressed, and the protruding rod (9) pulls the support plate (7) at the corresponding position through the traction steel rope (8), so that the support plate (7) moves downward, and the corresponding position of the single-chip microcomputer is detected by the detection probe (16); S2: When the detection track needs to be changed, the initial height of each detection probe (16) on each support plate (7) is adjusted by the adjustment component (14), and the initial position of the adjustment plate (29) is changed by screwing in or out the screw rod (12), thereby changing the extension length of the movable block (10) on the slide 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 support plates (7) at different positions moves downward by different distances, thereby detecting different positions of the single chip computer; S3: When the device performs a follow-up detection, the sliding plate (3) can slide on the bottom plate (1) through the switching component (5), and the mounting block (26) is installed in the mounting groove (25) to complete the engagement of the fixed shaft (24) and the first connecting ring (20). At this time, the extension plate (22) will not rotate on the partition (17). By screwing the screw rod (12) into the appropriate position in the slide seat (4), when the extension plate (22) abuts against the movable block (10), it will drive the slide seat (4) as a whole to slide on the bottom plate (1), thereby performing a follow-up detection. As the pressure of the movable block (10) gradually increases, the movable block (10) will be compressed into the interior of the slide seat (4). At this time, the slide seat (4) can be automatically reset by the switching component (5).
