Description

Technical Field

[0001] This utility model relates to the field of memory module testing technology, specifically to a memory module insertion and removal mechanism. Background Technology

[0002] In the field of semiconductor testing, especially in the testing of DDR5 memory chips, memory modules need to be frequently plugged in and out to complete a series of testing processes such as functional verification and performance testing. The efficiency and safety of the plugging and unplugging operations directly affect the overall progress and cost control of the testing work.

[0003] Currently, the mainstream method for inserting and removing memory modules in the industry is still mainly manual operation. When inserting and removing memory modules manually, it is difficult to accurately control the direction and balance of force. During the insertion and removal process, memory modules are prone to tilting or shifting, resulting in poor contact between the gold fingers of the memory module and the memory slot. This may not only cause errors in test data, but also cause physical damage to the pins of the memory slot and shorten the life of the slot. In addition, in large-scale testing scenarios, staff need to repeatedly press and insert and remove memory modules for a long time. Their fingers are in continuous contact with the edges and surfaces of the memory modules, resulting in pressure marks and pain on their fingers. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a memory module insertion and removal mechanism.

[0005] The purpose of this utility model is achieved through the following technical solution: a memory module insertion and removal mechanism, including a base; the base is provided with a lifting seat that can be raised and lowered; the lifting seat is provided with a limiting groove; clamping blocks are slidably provided at both ends of the lifting seat in the horizontal direction; a driving mechanism for driving the lifting seat to descend is provided between both ends of the lifting seat and both ends of the base; the driving mechanism is used to drive the clamping blocks to slide.

[0006] The present invention is further configured such that the driving mechanism includes a connecting rod; one end of the connecting rod is hinged to the end of the lifting seat; one end of the connecting rod is provided with a first arc-shaped protrusion, a second arc-shaped protrusion, and a flat portion disposed between the first arc-shaped protrusion and the second arc-shaped protrusion.

[0007] The present invention is further configured such that the clamping block includes a rod portion and a head portion connected to the rod portion; the rod portion is used to clamp the memory module; the end of the head portion away from the rod portion is provided with an arc-shaped surface; the arc-shaped surface is used to abut against the first arc-shaped protrusion, the second arc-shaped protrusion, and the flat portion.

[0015] The present invention will be further described in conjunction with the following embodiments.

[0016] Depend on Figures 1 to 4As can be seen, the memory module 1 insertion and removal mechanism described in this embodiment includes a base 2; the base 2 is provided with a lifting seat 3 for lifting and lowering; the lifting seat 3 is provided with a limiting groove 31; both ends of the lifting seat 3 are provided with clamping blocks 4 in the horizontal direction; a driving mechanism for driving the lifting seat 3 to descend is provided between both ends of the lifting seat 3 and both ends of the base 2; the driving mechanism is used to drive the clamping blocks 4 to slide.

[0017] Specifically, the memory module 1 insertion and removal mechanism described in this embodiment provides a vertical movement path for the insertion and removal of the memory module 1 through the lifting and lowering movement of the base 2 and the lifting seat 3; the limiting groove 31 on the lifting seat 3 can pre-position the memory module 1 to ensure that the memory module 1 is always in the preset position during operation and avoid lateral displacement; the clamping blocks 4 at both ends of the lifting seat 3 slide in the horizontal direction and can clamp the memory module 1 before insertion and removal to prevent it from shaking during vertical movement; the drive mechanism synchronously associates the lifting seat 3 and the clamping blocks 4, and can simultaneously drive the lifting seat 3 to rise and the clamping blocks 4 to slide, forming a coherent operation logic of positioning-clamping-lifting insertion and removal.

[0018] This embodiment, through the above-described design, solves the problem of memory module 1 tilting due to uneven force application during manual insertion and removal. The positioning groove 31 and clamping block 4 ensure that memory module 1 always aligns vertically with the memory slot, reducing misalignment and friction between the gold fingers and slot pins, protecting the memory slot from damage, and extending its lifespan. Furthermore, it eliminates the need for manual force application by directly holding the memory module 1; insertion and removal are completed solely through the drive mechanism, avoiding pressure marks and wear caused by direct contact between fingers and the memory module 1, thus improving operational comfort. This is particularly suitable for long-term operations in high-volume testing scenarios. The integrated drive design simplifies the operation process, reducing positioning and adjustment steps compared to manual insertion and removal, shortening the time per operation, improving the overall efficiency of the testing process, and reducing the risk of test interruptions due to human error.

[0019] The memory module 1 insertion and removal mechanism described in this embodiment includes a connecting rod 5; one end of the connecting rod 5 is hinged to the end of the lifting seat 3; one end of the connecting rod 5 is provided with a first arc-shaped protrusion 51, a second arc-shaped protrusion 52, and a flat portion 53 provided between the first arc-shaped protrusion 51 and the second arc-shaped protrusion 52.

[0020] Specifically, one end of the connecting rod 5 is hinged to the end of the lifting seat 3, and can swing synchronously with the lifting seat 3; the first arc-shaped protrusion 51, the second arc-shaped protrusion 52 and the flat part 53 at the end of the connecting rod 5 can transmit forces in different directions by changing the contact state with the clamping block 4; when the connecting rod 5 swings, the first arc-shaped protrusion 51 and the second arc-shaped protrusion 52 can push the clamping block 4 to slide horizontally, thereby clamping the memory module 1.

[0021] In this embodiment, a memory module 1 insertion / removal mechanism is described. The clamping block 4 includes a rod 42 and a head 41 connected to the rod 42. The rod 42 is used to clamp the memory module 1. The end of the head 41 away from the rod 42 has an arc-shaped surface 43. The arc-shaped surface 43 is used to abut against a first arc-shaped protrusion 51, a second arc-shaped protrusion 52, and a flat surface 53. In this embodiment, a return spring 44 is provided between the end of the head 41 near the rod 42 and the end of the lifting seat 3.

[0022] The rod portion 42 of the clamping block 4 directly contacts the memory module 1, undertaking the clamping and fixing function. The arc-shaped surface 43 of the head 41 away from the rod portion 42 can closely abut against the first arc-shaped protrusion 51, the second arc-shaped protrusion 52, and the flat surface 53 of the connecting rod 5. The smooth transmission of force is achieved through the curved surface contact. When the first arc-shaped protrusion 51, the second arc-shaped protrusion 52, and the flat surface 53 of the connecting rod 5 respectively contact the arc-shaped surface 43, the arc-shaped surface 43 can convert the rotational force of the connecting rod 5 into the sliding force of the clamping block 4 in the horizontal direction, while adapting to the rotation of the connecting rod 5 at different angles, ensuring that the contact state is always stable. In addition, when the clamping block 4 slides under the driving force of the connecting rod 5, the return spring 44 is compressed and stores elastic potential energy. When the driving force of the connecting rod 5 on the clamping block 4 disappears, the return spring 44 releases the elastic potential energy, pushing the clamping block 4 to slide in the opposite direction in the horizontal direction, returning to the initial position, and preparing for the next clamping operation.

[0023] The memory module 1 insertion and removal mechanism described in this embodiment includes a lifting base 3 with a guide block 32; the rod 42 is slidably disposed on the guide block 32. This arrangement prevents the rod 42 from shifting vertically or twisting during sliding.

[0024] The memory module 1 insertion and removal mechanism described in this embodiment includes a driving mechanism that further comprises a pressure handle 6; the middle part of the pressure handle 6 is hinged to the end of the base 2; one end of the pressure handle 6 is provided with a hinge portion 61; the hinge portion 61 is hinged to the other end of the connecting rod 5; the other end of the pressure handle 6 is bent to form a pressing portion 62. Specifically, the middle part of the pressure handle 6 is hinged to the end of the base 2 to form a lever structure, the pressing portion 62 is the force-applying end, and the hinge portion 61 is the power output end; when an upward force is applied to the pressing portion 62, the pressure handle 6 rotates around the middle hinge point, driving the hinge portion 61 to rotate synchronously, thereby pulling or pushing the connecting rod 5 to move, amplifying the manually applied hand force through the lever principle, and converting it into the power to drive the connecting rod 5, the lifting seat 3, and the clamping block 4 to move.

[0025] The memory module 1 insertion and removal mechanism described in this embodiment has a through-hole groove 21 provided in the base 2. This design prevents interference with the memory module 1.

[0026] The memory module 1 insertion and removal mechanism described in this embodiment includes a guide post 33 at the bottom of the lifting base 3 and a guide groove 22 that cooperates with the guide post 33. This configuration enables the lifting base 3 to perform stable lifting movements.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
