Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit testing, and in particular to an integrated circuit testing device with self-detection and adaptive limit. Background Art

[0002] Integrated circuits (ICs), as core components in modern electronic devices, have a significant impact on the stability and functionality of the entire system. With the continuous advancement of IC technology and increasingly complex design requirements, IC testing and verification are becoming increasingly important. Traditional testing methods often struggle to meet the demands for efficient, accurate, and adaptive testing, especially as systems become increasingly integrated.

[0003] Patent publication number CN114236349B discloses an integrated circuit test device. The device comprises a holder, a transparent plate, and a detector. The holder can be equipped with a clamping mechanism for clamping an integrated circuit board. First, electric push rod A moves downward to bring the integrated circuit board closer to the transparent plate. Then, electric push rod B is controlled to jump, causing the soldering pins on the integrated circuit board to contact the detection posts on the touch mechanism. The touch pins are then energized. This allows the contact between the pins and the detection posts to be measured. If the soldered pins are the same length, a specific result can be derived from the energization. If the integrated circuit board is bent, it can be restored to a flat structure on the holder. Furthermore, pressing the integrated circuit board closer to the transparent plate also restores it to a horizontal state. By calculating the contact status of the detection posts in the dot matrix, it is possible to analyze which pins do not meet manufacturing standards. Compared to existing technologies, this integrated circuit test device can detect both bent and horizontal circuit boards and analyze the overall situation from multiple groups of detection posts, with high accuracy. Although the above-mentioned device can realize the function of detecting bent circuit boards, it cannot cooperate with the conveyor belt to perform follow-up detection during use. During follow-up detection, the detection structure cannot be adaptively adjusted according to the detection position and spacing. Moreover, during the detection process, the circuit structures to be detected cannot enter the detection area one by one, resulting in low detection efficiency. Summary of the Invention

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

A threaded bushing 19 is provided on the outer side of the lifting assembly 18, and a cross plate 20 is slidably installed in the threaded bushing 19. A partition assembly 28 is installed on the threaded bushing 19. The partition assembly 28 cooperates with the folding plate 2 to guide and feed the conveyed circuit boards one by one. A sliding sleeve 21 is welded in the middle of the cross plate 20, and the sliding sleeve 21 and the connecting frame 15 are slidably connected. A fixed block 22 is welded on the sliding sleeve 21, and an adjustment assembly 23 is installed on the fixed block 22. A connecting plate 24 is welded on the fixed block 22, and a detector 25 is fixedly connected to the connecting plate 24. A detection probe 31 is installed on the detector 25, and a support assembly 27 is installed on the adjustment assembly 23. The support assembly 27 can adjust the installation spacing of the two detection probes 31 so as to adapt to the subsequent use of conductive contacts at different positions on the circuit structure. Both the transmission shaft 7 and the turntable 8 are provided with transverse convex grooves. When the device is in use, the first motor 6 drives the transmission shaft 7 to drive the turntable 8 to rotate. When the turntable 8 rotates, it can abut the connecting frame 15 through the first connecting block 10, so that the connecting frame 15 drives the sliding sleeve 21 to move left and right. As the turntable 8 continues to rotate, the pressure rod 14 can press down the cross plate 20 and the sliding sleeve 21 on the threaded bushing 19 below the lifting assembly 18, so that the device can perform follow-up detection when detecting the circuit. The initial position of the pressure rod 14 is adjusted by the first screw 11 to adapt to the subsequent use of circuit boards of different thicknesses.

[0034] In this embodiment, a through hole 29 is provided on the first connecting plate 4. The central axis of the through hole 29 is collinear with the central axis of the turntable 8 and the rotating drum 30. The through hole 29 facilitates the subsequent adjustment of the internal structure of the turntable 8. The top plate 3, the first connecting plate 4 and the second connecting plate 5 are fixedly connected to form an integral structure to ensure that the entire device can be stably supported.

[0035] In this embodiment, the turntable 8 forms a rotating structure between the rotating drum 30 and the first connecting plate 4. The front surface of the turntable 8 and the rear surface of the connecting frame 15 fit together to ensure the stability of the device during operation. The front surfaces of the connecting frame 15, the second connecting plate 5 and the first connecting block 10 are all in the same plane. The turntable 8 can be stably rotated on the first connecting plate 4 through the rotating drum 30.

[0036] In this embodiment, the slider 9, the first connecting block 10 and the pressure rod 14 are fixedly connected to form an integral structure. The pressure rod 14 forms a first sliding structure between the first screw 11 and the turntable 8. When the first screw 11 rotates, the radius of the circular motion of the pressure rod 14 will change so as to adapt to the subsequent use of circuit boards of different thicknesses. The connecting frame 15 forms a second sliding structure between the turntable 8 and the first connecting block 10 and the guide rod 17. The sliding sleeve 21 forms a third sliding structure between the connecting frame 15 and the threaded bushing 19. The fixed block 22 forms a lifting structure between the pressure rod 14 and the sliding sleeve 21 and the second connecting plate 5. The second sliding structure and the third sliding structure enable the device to follow the movement of the circuit board being conveyed and perform detection. The lifting structure allows the sliding sleeve 21 to be lifted and lowered while following the circuit board being conveyed.

[0037] In this embodiment, a rotating wheel 13 is fixedly connected to the first screw 11, and the rotating wheel 13 protrudes from the rear surface of the turntable 8, so that the device can rotate the rotating wheel 13 from the rear side of the turntable 8, thereby rotating the first screw 11, thereby enhancing the convenience of using the device.

[0038] In this embodiment, the lifting assembly 18 includes a protrusion 1801 and a fixed sleeve 1804 welded to the second connecting plate 5. The bottom of the protrusion 1801 is fixedly connected to a spring 1802, and the bottom of the spring 1802 is fixedly connected to a slide rod 1803. The bottom of the slide rod 1803 is rotatably connected to a second screw 1805. The second screw 1805 and the threaded bushing 19 are threadedly connected, and the slide rod 1803 and the fixed sleeve 1804 are slidingly connected. The device can change the initial height of the threaded bushing 19 by rotating the second screw 1805 under the slide rod 1803. The spring 1802 under the protrusion 1801 ensures that the threaded bushing 19 can be reset after being pressed down, and the fixed sleeve 1804 ensures that the slide rod 1803 can move vertically up and down.

[0039] In this embodiment, the adjustment assembly 23 includes a second motor 2301 fixedly mounted on the fixed block 22. A worm 2302 is fixedly connected to the output shaft of the second motor 2301. A worm gear 2303 is meshed with the worm 2302. A fixed shaft 2304 is fixedly mounted in the middle of the worm gear 2303. A rotating block 2305 is fixedly connected to the bottom of the fixed shaft 2304. A first connecting shell 2306 is mounted on the outer side of the rotating block 2305. A second connecting shell 2307 is fixedly connected to the first connecting shell 2306. This device can drive the worm 2302 to rotate via the second motor 2301 on the fixed block 22, thereby driving the worm gear 2303 to rotate, causing the fixed shaft 2304 and the rotating block 2305 to change the angle between the first connecting shell 2306 and the second connecting shell 2307 to facilitate subsequent adjustment of the detected position.

[0040] In this embodiment, a guide plate 26 is installed below the detector 25. The guide plate 26 and the second connecting shell 2307 are slidably connected. The detector 25 is supported by the guide plate 26. The guide plate 26 is an arc structure. The center of the arc of the guide plate 26 is located on the central axis of the fixed shaft 2304. When the second connecting shell 2307 on the device rotates, the position of the guide plate 26 remains unchanged.

[0041] In this embodiment, the support assembly 27 includes a connecting frame 2701 welded to the second connecting shell 2307, and a third motor 2702 is installed on the connecting frame 2701. A third screw 2703 is fixedly provided on the output shaft of the third motor 2702. The threads on the left and right sides of the third screw 2703 have opposite rotation directions. Movable blocks 2704 are threadedly installed on both sides of the third screw 2703. A rubber tube 2705 for placing the test lead 31 is fixedly provided on the movable block 2704. The third screw 2703 is driven to rotate by the third motor 2702 on the connecting frame 2701. When the third screw 2703 rotates, it can drive the two adjacent movable blocks 2704 to move toward or away from each other, thereby changing the distance between the two rubber tubes 2705. The rubber tube 2705 is made of rubber material so that it can clamp the test lead 31 and can realize the protection function after the test lead 31 is pressed down.

[0042] In this embodiment, the partition assembly 28 includes an extension plate 2801 fixedly connected to the threaded bushing 19, and a fourth screw 2802 is rotatably connected to the extension plate 2801. An adjustment block 2803 is installed on the outer thread of the fourth screw 2802, and a partition plate 2804 is fixedly provided on the adjustment block 2803. The device can rotate the fourth screw 2802 on the extension plate 2801 to make the adjustment block 2803 rise and fall, thereby changing the initial height of the partition plate 2804. Subsequently, when the threaded bushing 19 is reciprocated and lifted, the partition plate 2804 can be used to block the circuit board in the conveying process, thereby providing preliminary guidance for the circuit board.

[0043] It should be noted that the present invention is a self-detection adaptive limit integrated circuit testing device. First, as Figure 1 and Figure 3-Figure 6 As shown, the lower surface of the folding plate 2 only fits the belt surface of the conveyor belt 1. The fixed end of the folding plate 2 can be fixed to the ground or wall. The top plate 3 is fixed to the top of the wall. The entire device is supported by the top plate 3, the first connecting plate 4 and the second connecting plate 5. When the device is in use, the first motor 6 drives the transmission shaft 7 to drive the turntable 8 to rotate. When the turntable 8 rotates, it can drive the slider 9, the first connecting block 10 and the pressure rod 14 to perform circular motion. The first connecting block 10 can abut the inner wall of the opening 16 on the connecting frame 15, thereby driving the connecting frame 15 to slide left and right. The connecting frame 15 also drives the sliding sleeve 21 to move left and right. The cross plate 20 moves left and right in the threaded bushing 19. As the turntable 8 continues to rotate, the height of the pressure rod 14 gradually decreases, causing the pressure rod 14 to press down the sliding sleeve 21. When the sliding sleeve 21 moves downward, it causes the sliding rod 1803 on the lifting assembly 18 to slide in the fixed sleeve 1804, and the spring 1802 is stretched. The device can rotate the second screw 1805 to change the initial height of the threaded bushing 19, so that the lifting assembly 18 acts on the horizontal plate 20 and the sliding sleeve 21 on the threaded bushing 19 to change the initial height of the sliding sleeve 21, so that the device can not only perform follow-up detection by sliding the sliding sleeve 21 left and right when detecting the circuit, but also adjust the initial position of the pressure rod 14 through the first screw 11 to change the distance that the pressure rod 14 presses down the sliding sleeve 21, so that the sliding sleeve 21 and the fixed block 22 can move up and down with an adjustable distance when moving back and forth left and right, so as to adapt to follow-up detection work of circuit boards of different thicknesses.

[0044] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8As shown, during testing, the device can be adaptively adjusted according to the desired test location. The second motor 2301 drives the worm 2302 to rotate, thereby driving the worm wheel 2303 to rotate, causing the fixed shaft 2304 and the rotating block 2305 to rotate. The angles of the first connecting shell 2306 and the second connecting shell 2307 change, thereby changing the initial placement angle of the two test leads 31 below the tester 25. The third motor 2702 on the connecting frame 2701 drives the third screw 2703 to rotate. When rotating, the third screw 2703 can drive the two adjacent movable blocks 2704 to move toward or away from each other, thereby changing the spacing between the two rubber tubes 2705. The rubber material of the rubber tube 2705 is used to clamp the test leads 31 and provide a protective function when the test leads 31 are pressed down, allowing the device to adjust the spacing between the two test leads 31 for subsequent precise adjustment to different test locations on the circuit board. By rotating the fourth screw 2802 on the extension plate 2801, the adjustment block 2803 is raised and lowered, thereby changing the initial height of the partition plate 2804. When the threaded bushing 19 drives the partition plate 2804 to rise and fall, the partition plate 2804 can block the circuit board during the conveying process, thereby cooperating with the folding plate 2 to guide the circuit board, thereby accurately detecting the circuit.

In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation.
