Description

Technical Field

[0001] This invention relates to the field of memory testing technology, specifically to a memory testing device and method with automatic board insertion function. Background Technology

[0002] In today's rapidly evolving electronic devices, memory, as a core component responsible for data storage and retrieval, directly determines the operational efficiency and lifespan of electronic devices through its performance stability and data read / write accuracy. With the rapid development of consumer electronics, industrial control, and artificial intelligence, market demand for memory has surged, simultaneously placing higher demands on the accuracy and efficiency of memory quality testing. Comprehensive testing of memory before it leaves the factory has become a crucial step in ensuring product quality and reducing after-sales risks.

[0003] Currently, most memory testing processes rely on manual operation for core tasks such as insertion, testing, and removal. Operators manually insert the memory modules to be tested one by one into the test sockets, and then manually remove them after testing. This manual insertion and testing method has many drawbacks. Firstly, manual operation is extremely inefficient. Operators need to repeatedly insert and remove modules, resulting in high labor intensity and increased risk of fatigue and operational errors over long periods. This can lead to damage to the interface from excessive force during insertion, incomplete insertion affecting test results, or missed or incorrect detections, severely hindering the testing progress of large-scale memory production and failing to meet the testing requirements of mass production. Secondly, the accuracy of manual operation is limited. Different operators have varying insertion and removal force and angles, which can easily cause wear and tear on the memory pins and test sockets, shortening the lifespan of the test sockets and increasing the memory breakage rate, thus raising production costs.

A clamping rubber strip is fixedly installed on the side of the rotating clamp with the pressing protrusion.

[0009] Preferably, a rotating rod is fixedly installed at both ends of the detection port, and a rotating plate is fixedly installed at the end of one of the rotating rods away from the detection port. Four fixed arc-shaped blocks are fixedly installed on the outer side of the rotating plate, and a locking plate is fixedly installed at the end of the other rotating rod away from the detection port.

[0010] Preferably, outer sleeves are rotatably fitted onto the outer sides of both ends of the rotating roller, and a rotating rod is rotatably installed on the inner side of the outer sleeve. A protective disc is fixedly installed on one side of one of the outer sleeves, and a rotating plate is located inside the protective disc. A toothed ring is rotatably installed on one side of the protective disc. Four limiting plates are fixedly installed on the inner side of the toothed ring. An end plate is fixedly installed on the end of each of the four limiting plates away from the toothed ring. An inner sleeve post is fixedly installed between the end plate and the toothed ring. A movable arc-shaped block is rotatably installed between the end plate and the toothed ring. An outer sleeve groove is opened inside each of the movable arc-shaped blocks. A torsion spring is fitted onto the outer side of the inner sleeve post, and both ends of the torsion spring are fixedly connected to the outer side of the inner sleeve post and the inner side of the outer sleeve groove, respectively. Locking magnets are fixedly installed inside the other outer sleeve and the locking plate. Six locking magnets are installed inside the outer sleeve, and one locking magnet is installed inside the locking plate.

[0011] Preferably, each of the outer casings has a vertical rod fixedly installed at its bottom, and each of the vertical rods has a lifting protrusion fixedly installed on its opposite side.

[0013] Preferably, a fixing bracket is fixedly installed on the outer side of the outer sleeve, a fixing bracket is fixedly installed on one side of the fixing ring, the end of the fixing bracket away from the fixing ring is fixedly installed on both sides of the workbench, and four support legs are fixedly installed on the bottom of the workbench.

[0014] A method of using a memory testing device with automatic board insertion function includes the following steps: S1: First, insert the memory to be tested into the inside of the memory socket. Then, place multiple memory sockets carrying the memory inside the dropping frame, and let the moving seat slide outside the limiting slide plate inside the dropping frame through the limiting groove. At this time, the memory socket outside the bottommost memory contacts the top of the worktable.

[0015] S2: Then, the electric cylinder is activated. The output end of the electric cylinder can drive the moving block to move, thereby moving the slider inside the slide groove and moving the pusher plate on the top of the worktable. The end of the pusher plate is inserted into the limiting groove on one side of the moving seat, thereby moving the memory socket carrying the memory on the top of the worktable. In addition, when the moving block moves, it can drive the moving rod to move through the bending rod, thereby pushing the rack to move, thereby causing the toothed ring meshing with the rack to rotate in the opposite direction. The toothed ring rotating in the opposite direction can drive the movable arc block to move through the limiting plate, end plate and inner sleeve column. When the movable arc block touches the fixed arc block, it will rotate on the outside of the inner sleeve column through the outer groove, so that it will not drive the rotating plate to rotate through the fixed arc block. At this time, the position of one of the test seats corresponds to the position of the end of the worktable. The pusher plate finally inserts the memory into the detection socket inside the test seat through the moving seat and the memory socket. The memory is detected through the detection socket and the test seat. The surface of the test seat is equipped with a group of indicator lights, which light up according to the detection result.

[0016] S3: After the test is completed, the output end of the electric cylinder retracts, driving the moving block to move, thereby moving the pusher plate on the top of the worktable. The pusher plate passes the bottom of the dropping frame. At this time, the bottommost moving seat inside the dropping frame can carry the memory socket and memory downwards, and the bottommost memory socket touches the top of the worktable. The movement of the moving block can drive the bending rod, the moving rod and the rack to move, driving the toothed ring meshing with the rack to move clockwise. This drives the rotating plate to rotate through the movable arc block and the fixed arc block, thereby driving the rotating roller to rotate through the rotating rod, so that the next test seat body moves to a position aligned with the worktable.

[0017] S4: When the memory is pushed into the detection socket by the push-insertion assembly, the memory will press against the pressing protrusion, causing the rotating clamp to rotate and the clamping rubber strip to squeeze and fix the memory. When the rotating roller continues to rotate, the test seat with the memory inserted can be moved to the lifting protrusion position. When the arc-shaped protrusion passes the test seat, the test seat will apply pressure to the arc-shaped protrusion, thereby causing the rotating clamp to rotate. The memory is pulled out from the detection socket by pressing the protrusion, realizing the unloading.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: by inserting the memory to be tested into the inside of the memory socket, and then placing multiple memory sockets carrying the memory inside the dropping frame, and making the moving seat slide outside the limiting slide plate inside the dropping frame through the limiting groove, at this time the memory socket outside the bottommost memory contacts the top of the worktable, and then the pushing and inserting assembly can push the memory into the inside of the rotary detection assembly, the rotary detection assembly can perform quality monitoring on the memory, and automatically push the material after the detection is completed; Furthermore, the entire testing process is fully automated, from loading, pushing, and inserting the memory, to automatic reset after testing, switching to the next test stand, and automatic unloading of the memory after testing. This eliminates the need for operators to manually insert or remove the memory, effectively reducing the labor intensity of operators and minimizing errors that may occur during manual operation. It also significantly improves the testing efficiency and accuracy of the device, greatly enhancing its usability and practicality. It is suitable for continuous testing of large batches of memory.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 The present invention provides a technical solution: a memory testing device with automatic insertion function, including a workbench 1 and a memory 19. A push-insertion component is installed on the outside of the workbench 1, a rotation testing component is installed at one end of the workbench 1, a material dropping frame 2 is fixedly installed on the top of the workbench 1, a limiting slide plate 22 is fixedly installed inside the material dropping frame 2, a memory socket 20 is sleeved on the outside of the memory 19, a movable seat 21 is fixedly installed on one side of the memory socket 20, a limiting groove 35 is opened on one side of the movable seat 21, and the movable seat 21 is slidably installed on the outside of the limiting slide plate 22 through the limiting groove 35.

[0029] The working principle of the above technical solution is as follows: First, the memory 19 to be tested is inserted into the memory socket 20. Then, multiple memory sockets 20 carrying the memory 19 are placed inside the dropping frame 2, and the moving seat 21 slides outside the limiting slide plate 22 inside the dropping frame 2 through the limiting groove 35. At this time, the memory socket 20 outside the bottom memory 19 contacts the top of the workbench 1. Then, the push-insertion assembly can push the memory 19 into the interior of the rotary detection assembly. The rotary detection assembly can perform quality detection on the memory 19, and automatically push the material after the detection is completed. The entire detection process realizes fully automated operation from loading, pushing, and inserting the memory 19, to automatic reset after detection, switching to the next test seat 16, and automatic unloading of the memory 19 after detection. There is no need for operators to manually insert and remove the memory. This not only effectively reduces the labor intensity of operators and reduces the errors that may occur during manual operation, but also greatly improves the detection efficiency and detection accuracy of the device, significantly improving the overall use effect and practicality of the device. It is suitable for continuous detection of large batches of memory.

[0030] In another implementation scheme, such as Figures 1-7 As shown, the push-insertion assembly includes an electric cylinder 4, a movable block 34 is fixedly installed at the output end of the electric cylinder 4, a slider is fixedly installed on the top of the movable block 34, and a pusher plate 7 is fixedly installed on the top of the slider. The pusher plate 7 is slidably installed on the top of the worktable 1. The end of the pusher plate 7 corresponds to the position of the limiting groove 35, and the specifications of the end of the pusher plate 7 are compatible with the specifications of the inside of the limiting groove 35. A sliding groove 30 is opened inside the worktable 1, and the slider is slidably installed inside the sliding groove 30. A fixed frame 5 is fixedly installed at the bottom of the worktable 1, and the end of the electric cylinder 4 is fixedly installed inside the fixed frame 5.

[0031] By activating the electric cylinder 4, the output end of the electric cylinder 4 can drive the moving block 34 to move, thereby causing the slider to move inside the slide groove 30 and causing the pusher plate 7 to move on the top of the worktable 1, so that the end of the pusher plate 7 is inserted into the limiting groove 35 on one side of the moving seat 21, thereby causing the memory socket 20 to carry the memory 19 to move on the top of the worktable 1.

[0032] In another implementation scheme, such as Figures 1-7As shown, the rotating test assembly includes a rotating roller 3. Six connecting frames 28 are fixedly installed on the outer side of the rotating roller 3. A test base 16 is fixedly installed on the end of each of the six connecting frames 28 away from the rotating roller 3. A test socket 18 is fixedly installed on the side of the test base 16 away from the connecting frame 28. Rotating clamps 17 are movably installed on both sides of the end of the test base 16 away from the connecting frame 28. A pressing protrusion 38 is fixedly installed on one side of the rotating clamp 17, and an arc-shaped protrusion 15 is fixedly installed on the other side of the rotating clamp 17. A clamping rubber strip 39 is fixedly installed on the side of the rotating clamp 17 where the pressing protrusion 38 is installed. The two ends of the test socket 18... Each of the rotating rollers 3 is fixedly mounted with a rotating rod 37. A rotating plate 13 is fixedly mounted on the end of one rotating rod 37 furthest from the detection port 18. Four fixed arc-shaped blocks 14 are fixedly mounted on the outer side of the rotating plate 13. A locking plate 23 is fixedly mounted on the end of the other rotating rod 37 furthest from the detection port 18. Outer sleeves 26 are rotatably fitted onto the outer sides of both ends of the rotating roller 3, and the rotating rod 37 is rotatably mounted inside the outer sleeve 26. A protective disc 27 is fixedly mounted on one side of one outer sleeve 26, and the rotating plate 13 is located inside the protective disc 27. A toothed ring 12 is rotatably mounted on one side of the protective disc 27, and a fixed component is mounted on the inner side of the toothed ring 12. Four limiting plates 40 are provided, each with an end plate 11 fixedly installed at the end of each limiting plate 40 away from the toothed ring 12. An inner sleeve post 29 is fixedly installed between each end plate 11 and the toothed ring 12. A movable arc-shaped block 42 is rotatably installed between each end plate 11 and the toothed ring 12. Each movable arc-shaped block 42 has an outer sleeve groove 41 inside. A torsion spring 43 is sleeved on the outer side of the inner sleeve post 29, with both ends of the torsion spring 43 fixedly connected to the outer side of the inner sleeve post 29 and the inner side of the outer sleeve groove 41, respectively. Locking magnets 36 are fixedly installed inside another outer sleeve seat 26 and a locking plate 23. Six locking magnets 36 are installed inside the outer sleeve seat 26, and the locking... A locking magnet 36 is installed inside the plate 23. The magnetic poles of the locking magnet 36 inside the outer sleeve 26 and the locking magnet 36 inside the locking plate 23 are opposite. Vertical rods 32 are fixedly installed on the bottom of the outer sleeve 26. Lifting protrusions 33 are fixedly installed on the opposite sides of the vertical rods 32. A bent rod 8 is fixedly installed on one side of the moving block 34. A moving rod 31 is fixedly installed on one end of the bent rod 8. A rack 10 is fixedly installed on the end of the moving rod 31 away from the bent rod 8. The outer side of the rack 10 meshes with the outer side of the toothed ring 12. A guide seat 9 is fixedly installed on the bottom of the worktable 1, and the rack 10 is slidably installed on the inner side of the guide seat 9.

[0033] When the movable block 34 moves, it can drive the movable rod 31 to move via the bent rod 8, thereby pushing the rack 10 to move. This causes the gear ring 12, which meshes with the rack 10, to rotate in the opposite direction. The rotating gear ring 12 can drive the movable arc block 42 to move via the limiting plate 40, the end plate 11, and the inner sleeve post 29. When the movable arc block 42 touches the fixed arc block 14, it will rotate outside the inner sleeve post 29 via the outer groove 41, thus preventing the rotating plate 13 from rotating via the fixed arc block 14. At this time, the position of one of the test seats 16 corresponds to the end position of the workbench 1. The pusher plate 7 finally inserts the memory 19 via the movable seat 21 and the memory socket 20. Inside the test socket 18 within the test base 16, the memory 19 is tested via the test socket 18 and the test base 16. The surface of the test base 16 is equipped with an indicator light group, which illuminates according to the test results. The indicator light group typically includes green, red, and yellow indicator lights. A green indicator light indicates that the memory 19 has passed the test and all performance parameters meet the standards; a red indicator light indicates that the memory 19 has failed the test and has performance defects; a yellow indicator light indicates an abnormality during the test and requires retesting. The operator can quickly determine the test results of the memory based on the indicator light status. After the test is completed, the electric cylinder 4... The output end retracts, causing the moving block 34 to move, thus moving the pusher plate 7 on the top of the workbench 1. The pusher plate 7 passes the bottom of the dropping frame 2. At this time, the bottommost moving seat 21 inside the dropping frame 2 can carry the memory sleeve 20 and memory 19 downwards, causing the bottommost memory sleeve 20 to abut against the top of the workbench 1. The movement of the moving block 34 can also move the bending rod 8, the moving rod 31, and the rack 10, causing the toothed ring 12 meshing with the rack 10 to move clockwise. This, through the movable arc block 42 and the fixed arc block 14, drives the rotating plate 13 to rotate, which in turn drives the rotating roller 3 to rotate via the rotating rod 37, thus moving the next test seat. 16 moves to a position aligned with the workbench 1 to achieve continuous cyclic operation of the detection work. When the memory 19 is pushed into the detection socket 18 by the push-insertion assembly, the memory 19 will press against the pressing protrusion 38, causing the rotating clamp 17 to rotate and the clamping rubber strip 39 to squeeze and fix the memory 19. When the rotating roller 3 continues to rotate, the test seat 16 with the memory 19 inserted can be moved to the lifting protrusion 33 position. When the arc-shaped protrusion 15 passes by the test seat 16, the test seat 16 will apply pressure to the arc-shaped protrusion 15, causing the rotating clamp 17 to rotate. The memory 19 is pulled out from the detection socket 18 by pressing the protrusion 38, realizing material removal.

[0034] In another implementation scheme, such as Figures 1-7As shown, a fixing rod 25 is fixedly installed on the outer side of the outer sleeve 26, a fixing rod 25 is fixedly installed on one side of the fixing ring 24, and the end of the fixing rod 25 away from the fixing ring 24 is fixedly installed on both sides of the workbench 1. Four support legs 6 are fixedly installed on the bottom of the workbench 1.

[0035] The worktable 1 can be connected to the outer sleeve 26 by the fixed ring 24 and the fixed frame rod 25, so that the rotating roller 3 can be installed in the required position. The four support legs 6 can support the whole device and ensure the stability of the device during operation.

[0036] A method of using a memory testing device with automatic board insertion function includes the following steps: S1: First, insert the memory 19 to be tested into the inside of the memory socket 20. Then, place multiple memory sockets 20 carrying the memory 19 inside the dropping frame 2, and make the moving seat 21 slide outside the limiting slide plate 22 inside the dropping frame 2 through the limiting groove 35. At this time, the memory socket 20 outside the bottommost memory 19 is in contact with the top of the worktable 1.

[0037] S2: Then, the electric cylinder 4 is activated. The output end of the electric cylinder 4 can drive the moving block 34 to move, thereby moving the slider inside the slide groove 30 and causing the pusher plate 7 to move on the top of the worktable 1. The end of the pusher plate 7 is inserted into the limiting groove 35 on one side of the moving seat 21, thereby causing the memory socket 20 to carry the memory 19 to move on the top of the worktable 1. In addition, when the moving block 34 moves, it can drive the moving rod 31 to move through the bending rod 8, thereby pushing the rack 10 to move, thereby causing the toothed ring 12 meshing with the rack 10 to rotate in the opposite direction. The toothed ring 12 rotating in the opposite direction can be controlled by the limiting plate 40, the end plate 11 and The inner sleeve column 29 drives the movable arc block 42 to move. When the movable arc block 42 touches the fixed arc block 14, it will rotate on the outside of the inner sleeve column 29 through the outer sleeve groove 41, so that the rotating plate 13 will not be rotated through the fixed arc block 14. At this time, the position of one of the test seats 16 corresponds to the end position of the workbench 1. The pusher plate 7 finally inserts the memory 19 into the detection socket 18 inside the test seat 16 through the moving seat 21 and the memory socket 20. The memory 19 is detected through the detection socket 18 and the test seat 16. The surface of the test seat 16 is provided with a group of indicator lights, which light up according to the detection result.

[0038] S3: After the test is completed, the output end of the electric cylinder 4 retracts, driving the moving block 34 to move, thereby moving the pusher plate 7 on the top of the workbench 1, so that the pusher plate 7 passes the bottom of the dropping frame 2. At this time, the moving seat 21 at the bottom inside the dropping frame 2 can carry the memory socket 20 and memory 19 downwards, and make the bottom memory socket 20 abut against the top of the workbench 1. The movement of the moving block 34 can drive the bending rod 8, the moving rod 31 and the rack 10 to move, driving the toothed ring 12 meshing with the rack 10 to move clockwise, thereby driving the rotating plate 13 to rotate through the movable arc block 42 and the fixed arc block 14, thereby driving the rotating roller 3 to rotate through the rotating rod 37, so that the next test seat 16 moves to a position aligned with the workbench 1.

[0039] S4: When the memory 19 is pushed into the detection socket 18 by the push-insertion assembly, the memory 19 will press against the pressing protrusion 38, causing the rotating clamp 17 to rotate and the clamping rubber strip 39 to squeeze and fix the memory 19. When the rotating roller 3 continues to rotate, the test seat 16 with the memory 19 inserted can be moved to the lifting protrusion 33 position. When the arc-shaped protrusion 15 passes through the test seat 16, the test seat 16 will apply pressure to the arc-shaped protrusion 15, causing the rotating clamp 17 to rotate. The memory 19 is pulled out from the detection socket 18 by pressing the protrusion 38, realizing the unloading.

10. A method of using a memory testing device with automatic board insertion function according to claims 1-9, characterized in that: Includes the following steps: S1: First, insert the memory (19) to be tested into the inside of the memory socket (20). Then, place multiple memory sockets (20) carrying the memory (19) inside the dropping frame (2), and make the moving seat (21) slide outside the limiting slide plate (22) inside the dropping frame (2) through the limiting groove (35). At this time, the memory socket (20) outside the bottommost memory (19) is in contact with the top of the worktable (1). S2: Then start the electric cylinder (4). The output end of the electric cylinder (4) can drive the moving block (34) to move, so that the slider moves inside the slide groove (30) and the pusher plate (7) moves on the top of the worktable (1). The end of the pusher plate (7) is inserted into the limiting groove (35) on one side of the moving seat (21), so that the memory socket (20) carries the memory (19) to move on the top of the worktable (1). In addition, when the moving block (34) moves, it can drive the moving rod (31) to move through the bending rod (8), thereby pushing the rack (10) to move, so that the toothed ring (12) meshing with the rack (10) rotates in the opposite direction. The toothed ring (12) rotating in the opposite direction can be stopped by the limiting plate (40) and the end plate (11). The inner sleeve column (29) drives the movable arc block (42) to move. When the movable arc block (42) touches the fixed arc block (14), it will rotate on the outside of the inner sleeve column (29) through the outer sleeve groove (41), so that the fixed arc block (14) will not drive the rotating plate (13) to rotate. At this time, the position of one of the test seats (16) corresponds to the end position of the workbench (1). The push plate (7) finally inserts the memory (19) into the detection socket (18) inside the test seat (16) through the moving seat (21) and the memory socket (20). Thus, the memory (19) is detected through the detection socket (18) and the test seat (16). The surface of the test seat (16) is provided with a group of indicator lights, which light up according to the detection result. S3: After the test is completed, the output end of the electric cylinder (4) retracts, driving the moving block (34) to move, so that the push plate (7) moves on the top of the workbench (1), and the push plate (7) passes the bottom of the dropping frame (2). At this time, the bottommost moving seat (21) inside the dropping frame (2) can carry the memory socket (20) and memory (19) downwards, and the bottommost memory socket (20) touches the top of the workbench (1). The movement of the moving block (34) can drive the bending rod (8), the moving rod (31) and the rack (10) to move, driving the toothed ring (12) meshing with the rack (10) to move clockwise, so that the rotating plate (13) is driven to rotate through the movable arc block (42) and the fixed arc block (14), so that the rotating roller (3) is driven to rotate through the rotating rod (37), so that the next test seat (16) moves to a position that is aligned with the workbench (1). S4: When the memory (19) is pushed into the detection socket (18) by the push-insertion assembly, the memory (19) will press against the pressing protrusion (38), causing the rotating clamp (17) to rotate and the clamping rubber strip (39) to squeeze and fix the memory (19). When the rotating roller (3) continues to rotate, the test seat (16) with the memory (19) inserted can be moved to the lifting protrusion (33) position. When the arc protrusion (15) passes through the test seat (16), the test seat (16) will apply pressure to the arc protrusion (15), causing the rotating clamp (17) to rotate. The memory (19) is pulled out from the inside of the detection socket (18) by the pressing protrusion (38), thus realizing the unloading.
