Description

Technical Field

[0001] This utility model relates to the field of memory testing equipment technology, and in particular to a memory chip testing fixture. Background Technology

[0002] In the quality inspection process of DDR (Double Data Rate Memory) production, test fixtures are needed to test its read and write speeds. Test fixtures are support devices for test positioning. When testing products, the position of the product or product test seat must first be fixed. After fixing, the test operation begins. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of test fixtures.

[0003] In the prior art, application number 202322219994.3 proposes a storage particle testing fixture. In this fixture, the test piece is placed in a placement slot, and then a second electric push rod is activated to move the test plate downwards. The test contacts at the bottom of the test plate then contact the test piece to complete the functional test. The status of the warning lights on the test plate indicates whether the test piece is functionally complete and meets the standards. If any warning light is not lit, the test piece is considered unqualified. After the test is completed, the first electric push rod is activated again to move the movable plate upwards. The movable plate removes the placement plate from the groove, allowing the test piece to be removed from the placement plate. This facilitates loading and unloading, shortens the testing interval, and improves testing efficiency. The inclusion of a return spring buffers the impact force during testing, reducing damage to the test piece.

[0004] However, during the use of the above-mentioned patent, after the test is completed, it is necessary to stop the machine, remove the placement plate, take the test piece out of the placement slot of the placement plate, and then put the placement plate containing the test piece back in. This results in the test fixture being stopped for too long, reducing the test speed of the test fixture and making it impossible to continuously test the test piece. Based on the above problems, this application proposes a storage particle test fixture. Utility Model Content

Placement plates 21 are placed inside both the lifting plate 20 and the upper moving plate 12. A driving assembly is disposed on the rear side of the mounting frame 1. A mounting shell 22 is fixedly disposed on the top of the mounting frame 1. A testing assembly is disposed on the surface of the mounting shell 22. The driving assembly includes a fixed mounting... Mounting plate 2 is mounted on the rear side of mounting frame 1. A motor bracket 3 is fixedly mounted on the right side of mounting plate 2. A servo geared motor 4 is fixedly mounted on the right side of motor bracket 3. A coupling is fixedly mounted at the output end of servo geared motor 4. A lower screw 5 is mounted at the output end of servo geared motor 4 via the coupling. A lower screw sleeve 6 is threaded on the surface of lower screw 5. The lower screw sleeve 6 is fixedly mounted on the rear side of lower moving plate 13. A driving synchronous pulley 7 is fixedly mounted on the left end of lower screw 5. A synchronous belt 8 is meshed on the surface of driving synchronous pulley 7. A driven synchronous pulley 9 is meshed inside synchronous belt 8. An upper screw 10 is fixedly mounted inside driven synchronous pulley 9. The length of upper screw 10 is the same as the length of lower screw 5. The pitch of upper screw 10 is the same as the pitch of lower screw 5. The thread direction of upper screw 10 is... Opposite to the thread direction of the lower screw 5, the upper screw 10 is rotatably disposed inside the mounting plate 2. An upper screw sleeve 11 is threaded onto the surface of the upper screw 10. A connecting slot is provided through the rear side of the mounting frame 1. The lower screw sleeve 6 is slidably connected to the rectangular slot. A sliding slot is provided on the rear side of the mounting housing 22. The upper screw sleeve 11 is slidably connected to the sliding slot. The upper screw sleeve 11 is fixedly installed on the rear side of the upper moving plate 12. The lifting assembly includes an electric push rod 18 and a rectangular slot. The electric push rod 18 is fixedly installed at the bottom of the lower moving plate 13. The output end of the electric push rod 18 is fixedly installed at the bottom of the lifting plate 20. The rectangular slot is provided through the surface of the lower moving plate 13. Two guide plates 19 are slidably disposed inside the rectangular slot. There are two guide plates 19 symmetrically distributed, each with a T-shaped structure and made of metal. The top of the guide plate 19 is fixedly installed at the bottom of the lifting plate 20. The servo reduction motor 4 drives the coupling to rotate the lower screw 5. The lower screw 5 drives the upper screw 10 to rotate through the driving synchronous pulley 7, the synchronous belt 8, and the driven synchronous pulley 9. This causes the lower screw sleeve 6 and the upper screw sleeve 11 to simultaneously drive the lower moving plate 13 and the upper moving plate 12 to move. This causes the upper moving plate 12 to drive the support sleeve 14 to slide on the surface of the support rod 15, while the lower moving plate 13 drives the limiting sleeve 16 to slide on the surface of the limiting rod 17. This causes the upper moving plate 12 and the lower moving plate 13 to move in opposite directions at the same speed. The electric push rod 18 drives the lifting plate 20 through the lifting plate 20.The lifting plate 20 moves downwards, causing the top placement plate 21 of the lifting plate 20 to move out from the bottom of the upper moving plate 12. This swaps the positions of the left and right placement plates 21. The electric push rod 18 then drives the top placement plate 21 of the lifting plate 20 to reset, allowing the test pieces inside the placement plates 21 to be tested. This allows for simultaneous testing of test pieces in one placement plate 21 and removal of completed test pieces from the other placement plate 21, enabling continuous testing of the storage particle testing fixture. This avoids excessive downtime and reduces the testing speed, allowing more test pieces to be tested within the same timeframe.

[0018] Specifically, the test assembly includes an electric push rod 23 fixedly mounted on the top of the mounting housing 22. A connecting plate 24 is fixedly mounted on the output end of the electric push rod 23. A guide rod 25 is fixedly mounted on the top of the connecting plate 24. The guide rod 25 is slidably disposed inside the mounting housing 22. A buffer ring 26 is slidably disposed on the surface of the guide rod 25. A buffer spring 27 connects the bottom of the buffer ring 26 and the top of the mounting housing 22. A test plate 28 is fixedly mounted on the right side of the connecting plate 24. A warning light 29 is fixedly mounted on the top of the test plate 28. The test piece is placed inside the placement slot on the placement plate 21 and controlled by an external controller. The electric push rod 23 drives the output end to move the connecting plate 24 downward. The connecting plate 24 drives the guide rod 25 downward, which in turn pushes the buffer ring 26 to compress the buffer spring 27. This causes the test plate 28 to move the warning light 29 downward. After the test contact point at the bottom of the test plate 28 contacts the test piece, the functional test is completed. The working status of the warning light 29 on the test plate 28 is used to determine whether the function of the test piece is complete and qualified. If any warning light 29 is not lit, it indicates that the test piece is unqualified, thus facilitating the testing of unqualified individuals within the test piece.

[0019] The memory chip testing fixture is connected to a 220V AC mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0020] In use: The servo geared motor 4, controlled by an external controller, drives the coupling to rotate the lower screw 5. The lower screw 5 then drives the active synchronous pulley 7 to rotate. The active synchronous pulley 7, via the synchronous belt 8, drives the driven synchronous pulley 9 to rotate, which in turn drives the upper screw 10 to rotate. This causes the lower screw 5 and the upper screw 10 to simultaneously drive the lower screw sleeve 6 and the upper screw sleeve 11 to move. The lower screw sleeve 6 and the upper screw sleeve 11, in turn, drive the lower moving plate 13 and the upper moving plate 12 to move. This causes the upper moving plate 12 to drive the support sleeve 14 to slide on the surface of the support rod 15, while the lower moving plate 13 drives the limiting sleeve 16 to slide on the surface of the limiting rod 17. This results in the upper moving plate 12 and the lower moving plate 13 moving in opposite directions at the same speed. As the lower moving plate 13 moves, the output end of the electric push rod 18 drives the lifting plate 20 to move downwards, causing the lifting plate 20 to drive the guide plate 19 within the rectangular through slot. The sliding mechanism causes the lifting plate 20 to move downwards, moving the top placement plate 21 downwards. This allows the lifting plate 20 to move out from the bottom of the upper moving plate 12, moving the upper moving plate 12 to the right and the lower moving plate 13 to the left. The electric push rod 18 then drives the lifting plate 20 to reset, causing the top placement plate 21 to reset as well. The test piece placed in the placement plate 21 on the top of the lifting plate 20 is then tested. Simultaneously, the placement plate 21 on the top of the upper moving plate 12 can be removed, and the tested piece can be removed from the placement plate 21 and replaced with the test piece. The placement plate 21 is then placed back inside the upper moving plate 12. This process can be performed while the test piece is being tested in the placement plate 21 on the top of the lifting plate 20. After the test is completed, the positions of the left and right placement plates 21 are swapped again to complete continuous testing of the test piece.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
