Description

Technical Field

[0001] This utility model relates to hard disk testing technology, and more particularly to a vertical insertion and removal fixture for an SSD testing machine. Background Technology

[0002] In the mass production of solid-state drives (SSDs), pre-shipment functional and performance testing is a crucial step in ensuring product quality. The testing equipment needs to establish a stable and reliable electrical connection with the SSD. Currently, the fixtures or methods used to achieve this connection process mainly fall into the following categories, all of which have significant limitations: Typically, it is a carrier with a limit slot. The operator manually inserts the SSD, aligns it with the interface, and then forcefully inserts it into the test machine's female connector.

[0003] It relies entirely on the operator's feel and experience. Applying too little force may result in poor contact; applying too much force or slightly off-center angle can easily cause scratches and wear on the SSD's gold fingers, or even deform or collapse the spring contacts of the test machine's female connector, leading to high repair costs. Repetitive and delicate insertion and removal actions can easily cause operator fatigue, resulting not only in low test throughput but also increased long-term labor costs.

[0004] To replace manual operation, jigs using pneumatic or electric cylinders as power sources have appeared on the market. Through program control, a pressure head is driven to vertically press the SSD into the interface.

[0005] These fixtures are rigid and lack fault tolerance. They require the robotic arm to place the SSD in the fixture at a very precise position, or the SSD must be positioned relative to the test interface. This places stringent demands on the repeatability of the robotic arm and the machining accuracy of the fixture, significantly increasing equipment costs.

[0006] Even under ideal alignment, rapid, rigid pressing can generate a tremendous impact force at the moment of contact, which can adversely affect the lifespan of the interface over time. Even a slight deviation will inevitably cause damage.

[0007] Some improved fixtures have a guide ramp at the interface entrance to solve the alignment problem.

[0008] Simple chamfering can only correct very small initial positional deviations. For cases where there are angular deviations between connectors, it is essentially impossible to correct them, and may even cause the SSD to jam or generate greater lateral stress due to the chamfer. Even after successful guidance, the final insertion and removal action is often still rigid, failing to eliminate end-point impact.

[0009] Therefore, there is an urgent need in this field for a technology that can adaptively compensate for various position and angle deviations, achieve smooth and non-destructive vertical insertion and removal, and also has the ability to quickly change models. Utility Model Content

[0010] In summary, this utility model proposes a vertical insertion and removal fixture for an SSD testing machine.

[0011] The technical solution of this utility model is implemented as follows: A vertical insertion / removal fixture for an SSD testing machine includes a base frame and a positioning module. The base frame comprises a floating frame and a floating platform, wherein the floating frame is buoyantly mounted on the floating platform via a guide rod and a first spring. The positioning module is mounted on the floating frame, and the positioning module includes a positioning base and an alignment component for positioning the SSD hard drive. The alignment assembly includes a movable clamping block for clamping the SSD hard drive and a guide block for providing guidance during insertion and removal.

[0012] Preferably, the floating platform consists of two support frames and a connecting frame, with the connecting frame fixedly installed between the two support frames, and the floating frame slidably connected to the floating platform via guide rods.

[0013] Preferably, the positioning base includes a horizontal plate assembly and side plates. The horizontal plate assembly consists of a bottom plate and a top plate, and guide grooves are provided on the bottom plate, top plate, and side plates.

[0014] Preferably, the alignment assembly includes a guide plate, on which a guide rail and a plurality of bead slots are provided, and the clamping block engages with the bead slots via a second spring and bead slots.

[0015] Preferably, the clamping block includes a block body, on which a retaining bead is provided by a second spring, and the retaining bead engages with the retaining bead groove.

[0016] Preferably, the guide block includes a base block and a conical block.

[0017] Preferably, the alignment component is detachably mounted on the positioning base.

[0018] Preferably, the alignment assembly includes multiple clamping blocks, each of which moves independently and clamps an SSD hard drive.

[0019] Preferably, the first spring is compressed during insertion and removal, causing the floating frame to float slightly in the vertical direction to absorb impact force and compensate for positional deviation.

[0020] Preferably, the base frame is used for rigid connection with the testing machine platform to provide overall support.

[0021] The vertical insertion and removal fixture for an SSD testing machine according to this utility model has the following beneficial effects: Through the design of the floating frame and spring buffer mechanism, the fixture allows the entire positioning module to float slightly during vertical insertion and removal, which can automatically compensate for positional deviations (such as X / Y directions) and angular deviations between the SSD and the test interface. The tapered structure of the guide block provides guidance upon initial contact, converting horizontal deviations into guiding forces to achieve precise alignment and avoid jamming or lateral stress caused by misalignment.

[0022] The end stroke of the insertion / removal process employs a spring-buffered mechanism, transforming rigid impact into flexible stroke, significantly reducing the impact force at the moment of insertion / removal. This effectively protects the SSD gold fingers and the test machine socket springs, preventing scratches, wear, or deformation, extending equipment lifespan, and improving connection reliability.

[0023] The positioning module employs multiple independently adjustable clamps, clamping and supporting each SSD independently. Precise positioning is achieved through the interaction of the locking beads and locking bead slots. This design ensures the stability of the SSD's position during insertion and removal, while also absorbing lateral or torsional forces from individual SSDs, preventing damage caused by stress concentration.

[0024] The positioning module and alignment components of the fixture are designed to be detachable and adjustable. The guide groove spacing and width can be quickly adjusted or replaced according to different specifications of SSDs, adapting to diverse production needs, greatly improving the flexibility and changeover efficiency of the fixture, and reducing equipment configuration costs.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Reference Figures 1 to 8 As shown in the figure, this embodiment proposes a vertical insertion and removal fixture for an SSD testing machine, including a base frame 10 and a positioning module 20.

[0029] The base frame 10 is used to rigidly connect with the test machine platform and provide overall support; the operator or robot arm inserts the SSD hard drive 30 into the positioning module 20.

[0030] Furthermore, refer to again Figure 1 As shown, the base frame 10 includes two support frames 101, a connecting frame 102, and a floating frame 103. The connecting frame 102 is fixedly installed between the two support frames 101 to form a floating platform.

[0031] A guide rod 104 is installed at the bottom of the floating frame 103, and the floating frame 103 is slidably mounted on the floating platform composed of two support frames 101 and a connecting frame 102 via the guide rod 104. A first spring 105 is provided between the bottom of the floating frame 103 and the connecting frame 102.

[0032] Furthermore, the positioning module 20 is installed on the top of the floating frame 103. The positioning module 20 includes a horizontal plate assembly 201 and a side plate 202. The horizontal plate assembly 201 is composed of a bottom plate 201A and a top plate 201B.

[0033] The base plate 201A, top plate 201B and side plate 202 form a rectangular positioning base. Guide grooves for mounting the SSD hard drive 30 are provided on the base plate 201A, top plate 201B and side plate 202. The spacing and width of the guide grooves are adjustable according to the different specifications of the SSD hard drive 30.

[0034] In this embodiment, an alignment component is installed above the top plate 201B. The alignment component is detachably connected to the top plate 201B. The lower part of the alignment component is connected to the positioning base and can be replaced according to different specifications of SSD hard drives 30.

[0035] The alignment assembly includes a guide plate 203, within which a plurality of clamping blocks 204 are slidably connected, and a guide block 205 is mounted on the top of each clamping block 204.

[0036] Among them, in reference again Figures 6 to 8 As shown, the guide plate 203 consists of a base frame 203A, guide rails 203B on both sides of the base frame 203A, and multiple bead slots 203C located in a straight line on the guide rails 203B.

[0037] The clamping block 204 includes a block 204A. The part of the block 204A connected to the guide rail 203B is provided with a retaining bead 204B by a second spring 204C. The retaining bead 204B engages with a retaining bead groove 203C on the guide rail 203B to achieve the positioning of the block 204A.

[0038] Furthermore, the guide block 205 is composed of a base block 205A and a conical block 205B.

[0039] In this embodiment, the base frame 10 of the fixture is rigidly connected to the testing machine platform, providing stable support. The positioning module 20 is mounted on the floating frame 103, which is slidably connected to the floating platform formed by the support frame 101 and the connecting frame 102 via guide rods 104, and is cushioned by a first spring 105. The multiple clamps 204 in the alignment assembly are initially pressed against one side (such as the left or right side) in a retracted state, awaiting the insertion of the SSD hard drive 30.

[0040] An operator or robotic arm inserts an SSD hard drive 30 into the positioning module 20. For each SSD hard drive 30 installed, a corresponding clamping block 204 is moved, bringing it into contact with the side wall of the SSD hard drive 30. The clamping block 204 slides on the guide rail 203B of the guide plate 203, and its locking mechanism, driven by a second spring 204C, engages with the locking ball slot 203C to achieve precise positioning and locking. Each SSD hard drive 30 is independently clamped, ensuring its stable position.

[0041] When the SSD 30 is pressed into the test interface, the floating bracket 103, cushioned by the first spring 105, allows the entire positioning module 20 to float slightly in the vertical direction. This absorbs the impact force during insertion and removal and compensates for positional and angular deviations between the SSD 30 and the test interface. The tapered block 205B of the guide block 205 provides initial guidance, corrects minor deviations, and avoids jamming or lateral stress. As the insertion and removal operation continues, the first spring 105 further softens the contact, achieving a lossless connection.

[0042] As the fixture continues to press down, the SSD's 30 gold fingers make smooth contact with the test socket. At this point, the first spring 105 is compressed, and the final segment of the entire insertion / removal process involves a flexible spring travel rather than a rigid impact. This significantly reduces the impact force during insertion and removal, effectively protecting the SSD's 30 gold fingers and the test socket's spring contacts, thus extending the equipment's lifespan.

[0043] Specifically, the guide block 205 at the top of each clamping block 204 has a tapered block 205B at its end. When the fixture is pressed down, before the SSD hard drive 30 interface contacts the test machine socket, the tapered block 205B will first contact the guide port of the socket. Even if there is a slight horizontal (X / Y direction) misalignment of the SSD hard drive 30, the tapered surface will convert the horizontal deviation into a guiding force, pushing the entire floating frame 103 and positioning module 20 to produce a slight slip in the horizontal plane, thereby allowing the connector of the SSD hard drive 30 to be precisely aligned with the test socket.

[0044] Since each clamping block 204 and its corresponding SSD hard drive 30 are clamped and supported independently, there are slight angular deviations between multiple SSD hard drives 30 or between a single SSD hard drive 30 and the interface. During insertion and removal, the lateral force or torque acting on the SSD 30 is absorbed by its corresponding independent clamping block 204, and will cause a slight deflection of the floating platform, instead of completely rigidly transmitting the stress like a rigid fixture, thus preventing scratches on the gold fingers or damage to the interface.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
