DETAILED DESCRIPTION

Hereinafter, various embodiments are described with reference to the accompanying drawings.

FIG. 1 is a view illustrating an automated storage device test system 1 according to one or more embodiments.

Referring to FIG. 1, the automated storage device test system 1 may include a first storage device 101, a second storage device 102, a test device 200, a storage rack 300, and a robot arm 500.

The first and second storage devices 101 and 102 may include nonvolatile memory devices. In one or more embodiments, the first and second storage devices 101 and 102 may be provided as memory devices which are built in or detachable from an electronic device. For example, the first and second storage devices 101 and 102 may be provided in various forms, such as an embedded universal flash storage (UFS) memory device, an embedded multi-media card (eMMC), a solid state drive (SSD), a UFS memory card, a compact flash (CF) memory card, a secure digital (SD) memory card, a micro secure digital (micro-SD) memory card, a mini secure digital (mini-SD) memory card, an extreme digital (xD) memory card, and a memory stick.

The test device 200 may perform a plurality of test operations to test the first and second storage devices 101 and 102. For example, the test device 200 may performs a write operation and a read operation on the first and second storage devices 101 and 102 and test the characteristics of the first and second storage devices 101 and 102 based on the write and read operations.

A first cable connector (cCONNECTOR 1) 221 and a second cable connector (cCONNECTOR 2) 222 may be coupled and fixed to the storage rack 300. Specifically, multi connector grips 400 may be coupled and fixed to the storage rack 300 while respectively gripping the first and second cable connectors 221 and 222. The first cable connector 221 may be connected to the test device 200 via a first cable 211, and the second cable connector 222 may be connected to the test device 200 via a second cable 212.

The first and second storage devices 101 and 102 may be inserted into first and second slots 311 and 312, respectively, which are provided in the storage rack 300. Specifically, the robot arm 500 may move based on the coordinates of the first and second slots 311 and 312 and insert the first and second storage devices 101 and 102 into first and second slots 311 and 312, respectively, at positions to which the robot arm 500 moves.

When the robot arm 500 inserts the first storage device 101 into the first slot 311, a first storage connector (sCONNECTOR 1) 111 of the first storage device 101 may be connected to the first cable connector 221. When the robot arm 500 inserts the second storage device 102 into the second slot 312, a second storage connector (sCONNECTOR 2) 112 of the second storage device 102 may be connected to the second cable connector 222.

Each of the first and second storage devices 101 and 102 may communicate with the test device 200 via one of various interfaces. Each of the first and second storage devices 101 and 102 may communicate with the test device 200 via various interfaces, such as a universal serial bus (USB), a multimedia card (MMC), an embedded MMC (eMMC), a peripheral component interconnection (PCI), a PCI-express (PCI-E), an advanced technology attachment (ATA), a serial-ATA, a parallel-ATA, a small computer small interface (SCSI), an enhanced small disk interface (ESDI), integrated drive electronics (IDE), a firewire, a UFS, and a nonvolatile memory express (NVMe).

In one or more embodiments, the first cable connector 221 and the second cable connector 222 may be configured according to the same connector standard. For example, the first cable connector 221 and the second cable connector 222 may be configured according to one connector standard among M.2, U.2, enterprise and data center standard form factor (EDSFF), and mini-serial advanced technology attachment (mSATA). For example, the first cable connector 221 and the second cable connector 222 may have the same pin map. Specifically, the numbers and types of pins in the first cable connector 221 and the second cable connector 222 may be same. The pin maps of the first cable connector 221 and the second cable connector 222 may be set based on the same standard specification.

Even though the first cable connector 221 and the second cable connector 222 are configured according to the same connector standard, the characteristics of signals transmitted/received via the first cable connector 221 and the second cable connector 222 may be different from each other depending on the structures of the first cable connector 221 and the second cable connector 222. In one or more embodiments, the characteristics (e.g., a voltage level, a delay time, a signal integrity, an eye diagram, etc.) of signals transmitted/received via a first pin of the first cable connector 221 may be different from the characteristics of signals transmitted/received via a first pin of the second cable connector 222. The structures of the first cable connector 221 and the second cable connector 222 may be different from each other depending on manufacturers. When evaluating storage devices, different cable connectors may be used depending on the signals to be evaluated. Accordingly, repeated coupling and decoupling between the cable connector and the storage connector may be performed to evaluate various signals.

However, when coupling and decoupling between the first and second cable connectors 221 and 222 and the first and second storage connectors 111 and 112 are repeated, the positions of the first and second cable connectors 221 and 222 may change. When the robot arm 500 attempts to respectively connect the first and second cable connectors 221 and 222 and the first and second storage connectors 111 and 112 to each other in a state in which the positions of the first and second cable connectors 221 and 222 have changed, contact failure or connector damage may occur.

The multi connector grips 400 according to one or more embodiments are fixed to the storage rack 300 and respectively grip the first and second cable connectors 221 and 222, and thus, the coupling positions of the first and second cable connectors 221 and 222 may be fixed. Also, each of coupling surfaces of the multi connector grips 400 may have a structure optimized to grip the corresponding cable connector. For example, a first coupling surface of the multi connector grip 400 may have a structure that matches the first cable connector 221, and a second coupling surface of the multi connector grip 400 may have a structure that matches the second cable connector 222.

Therefore, the multi connector grip 400 may establish connections between the first and second storage connectors 111 and 112 and the first and second cable connectors 221 and 222 using the robot arm 500 without poor contact or damage to connectors.

FIGS. 2A to 2C are views illustrating the automated storage device test system 1 according to one or more embodiments. FIGS. 2A to 2C may be described below with reference to FIG. 1.

Referring to FIG. 2A, the automated storage device test system 1 may include a storage tray 520 and the robot arm 500.

The storage tray 520 may be provided as a movable or fixed type. The storage tray 520 may accommodate various storage devices (e.g., 101 and 102 in FIG. 1). The robot arm 500 may move freely within a movable range 510 having a spherical shape. The robot arm 500 may insert storage devices, which are stored in the storage tray 520, into slots (e.g., 311 and 312 in FIG. 1) of the storage rack 300. The robot arm 500 may include a plurality of joints, and each of the joints may include a motor that provides rotational movement.

When the robot arm 500 inserts the storage device into the slot, the storage connector of the storage device and the cable connector may be connected to each other. Since the cable connector is fixed to the slot in advance by the multi connector grip (400 in FIG. 1), the position of the cable connector may be maintained constant (remain fixed). Accordingly, even if the insertion of the storage device is repeated based on the coordinates of the slot, a smooth connection between the storage connector and the cable connector is possible.

Referring to FIG. 2B, the storage rack 300 may include at least one slot 310. The slots 310 may include spaces into which the storage devices (e.g., 101 and 102 in FIG. 1) are inserted. The robot arm 500 may approach the slot 310 based on the coordinates of the slot 310 and insert the storage device into the slot 310.

Referring to FIG. 2C, an end-of-arm 501 of the robot arm 500 may push a storage device 100 into the slot 310. When the end-of-arm 501 places the storage device 100 into the slot 310, the storage connector of the storage device 100 and the cable connector may be connected to each other. The cable connector may be fixed to the slot 310 in advance. Specifically, the multi connector grip (400 in FIG. 1) may be coupled to the storage rack 300 while gripping the cable connector. The position of the cable connector is maintained even when repeated test operations are performed, and thus, the connection between the storage connector and the cable connector may be established without poor contact between the cable connector and the storage connector or damage to the cable connector and the storage connector.

FIG. 3 is a view illustrating insertion of first and second storage devices 101 and 102 according to one or more embodiments. FIG. 3 may be described below with reference to FIGS. 1 and 2.

Referring to FIG. 3, the first and second storage devices 101 and 102 may be inserted into first and second slots 311 and 312, respectively, by a robot arm 500. Although the first and second storage devices 102 and 102 are illustrated as being inserted in a Y-axis direction, embodiments are not limited thereto. The first and second storage devices 101 and 102 may be inserted into the first and second slots 311 and 312 in various directions.

The multi connector grip 400 of FIG. 1 may be coupled to the storage rack 300, corresponding to each of the first and second slots 311 and 312. Specifically, the storage rack 300 may include a board 320, and the multi connector grip 400 may be coupled to the board 320. Corresponding to the first slot 311, the multi connector grip 400 may be coupled to the board 320 while a first coupling surface of the multi connector grip 400 grips a first cable connector 221. Corresponding to the second slot 312, the multi connector grip 400 may be coupled to the board 320 while a second coupling surface of the multi connector grip 400 grips a second cable connector 222.

As the first and second storage devices 101 and 102 are inserted into the first and second slots 311 and 312, respectively, the first and second storage connectors 111 and 112 may be connected to the first and second cable connectors 221 and 222, respectively, which are gripped by the multi connector grip 400.

FIGS. 4A and 4B are views illustrating first and second cable connectors 221 and 222 according to one or more embodiments. Specifically, FIG. 4A is a plan view of the first and second cable connectors 221 and 222 in the Y-axis direction, and FIG. 4B is a plan view of the first and second cable connectors 221 and 222 in the Z-axis direction.

As used herein, the length of a cable connector in the Z-axis direction may be referred to as a height, the length of the cable connector in the X-axis direction may be referred to as a width, and the length of the cable connector in the Y-axis direction may be referred to as a depth.

Referring to FIG. 4A, the first cable connector 221 and the second cable connector 222 may have the same pin map. That is, the numbers and types of pins in the first cable connector 221 and the second cable connector 222 may be same. The pin maps of the first cable connector 221 and the second cable connector 222 may be formed based on the same standard specification.

The first cable connector 221 may have a first height H1 and a first width W1. The second cable connector 222 may have a second height H2 and a second width W2. The housing size of a cable connector may vary depending on the manufacturers of the cable connector. That is, the first height H1 and the second height H2 may be different from each other, and the first width W1 and the second width W2 may be different from each other. The first height H1 may be greater than the second height H2 by a height difference dH.

Referring to FIG. 4B, the first cable connector 221 may have a first depth D1, and the second cable connector 222 may have a second depth D2. The first depth D1 and the second depth D2 may be different from each other. The first depth D1 may be less than the second depth D2 by a depth difference dD. Dip structures 231 and 232 may be formed on the upper surface of the second cable connector 222. The dip structures 231 and 232 may include concave portions on the upper surface of the second cable connector 222.

According to one or more embodiments, a multi connector grip 400 may include coupling surfaces having different structures depending on the dimensions of the first and second cable connectors 221 and 222. That is, a first surface of the multi connector grip 400 may match the structure of the first cable connector 221, and a second surface of the multi connector grip 400 may match the structure of the second cable connector 222. Accordingly, the multi connector grip 400 may provide compatibility for gripping a plurality of cable connectors.

FIGS. 5A and 5B are views illustrating a multi connector grip 400 according to one or more embodiments. Specifically, FIG. 5A is a plan view of the multi connector grip 400 in the Y-axis direction, and FIG. 5B is a plan view of the multi connector grip 400 in the X-axis direction.

Referring to FIG. 5A, the multi connector grip 400 may have two coupling surfaces. The upper coupling surface may be used when gripping a first cable connector 221, and the lower coupling surface may be used when gripping a second cable connector 222. Referring to FIG. 5A, when viewed in the Y-axis direction, the outline of the multi connector grip 400 may have an H shape with a first total height tH1 and a first total width tW1.

Referring to FIG. 5B, when viewed in the X-axis direction, the outline of the multi connector grip 400 may have a rectangular shape with the first total height tH1 and a first total depth tD1. A first support member 401 and a second support member 402 may protrude in the (+)Y-axis or (−)Y-axis direction. The first cable 211 may be seated on the first support member 401, and the second cable 212 may be seated on the second support member 402.

The multi connector grip 400 grips the first cable connector 221 and the second cable connector 222 using the upper and lower coupling surfaces that are opposite to each other in the Z-axis direction, and thus, the first total height tH1 of the multi connector grip 400 may be greater than the sum of the first height H1 and the second height H2. In the multi connector grip 400, a space for gripping the first cable connector 221 and a space for gripping the second cable connector 222 may at least partially overlap each other in the Z-axis direction. Accordingly, the first total depth tD1 of the multi connector grip 400 may be less than the sum of the first depth D1 and the second depth D2.

FIGS. 6A and 6B are views illustrating a multi connector grip 400 that grips a first cable connector 221 according to one or more embodiments.

Referring to FIG. 6A, the upper coupling surface of the multi connector grip 400 may have a structure that grips the first cable connector 221.

Specifically, a first cable 211 may be seated in a first cable groove 411 on the upper coupling surface, and the first cable connector 221 may be gripped in a first cable connector groove 412 on the upper coupling surface.

The first cable groove 411 may be formed in a size to accommodate the first cable 211. Specifically, the first cable groove 411 may have a first cable groove width coW1, a first cable groove depth coD1, and a first cable groove height coH1. The first cable groove depth coD1 may have a value obtained by subtracting a first cable connector groove depth ccoD1 from a total depth tD. The first cable groove width coW1 may be greater than the width of the first cable 211. The first cable groove height coH1 may be greater than the thickness of the first cable 211.

The first cable connector groove 412 may grip the exterior of the first cable connector 221. Specifically, the first cable connector groove 412 may have a first cable connector groove width ccoW1, the first cable connector groove depth ccoD1, and a first cable connector groove height ccoH1. Referring to FIGS. 4A and 4B, the first cable connector groove width ccoW1 may be equal to the first width W1. The first cable connector groove height ccoH1 may be equal to the first height H1. The first cable connector groove depth ccoD1 may be less than the first depth D1. However, embodiments are not limited thereto, and the first cable connector groove depth ccoD1 may be equal to or greater than the first depth D1. Also, the first cable connector groove width ccoW1, the first cable connector groove depth ccoD1, and the first cable connector groove height ccoH1 may be set such that the first cable connector groove 412 grips the exterior of the first cable connector 221.

The first cable connector groove width ccoW1 may be greater than the first cable groove width coW1. The first cable connector 221 is gripped in the first cable connector groove 412, and the first cable 211 is seated in the first cable groove 411. Accordingly, the first cable connector 221 may be prevented from being separated in the Y-axis direction.

Referring to FIGS. 4A, 4B, 6A, and 7A, the first cable connector groove depth ccoD1 may be less than a second cable connector groove depth ccoD2 of FIG. 7A by a depth difference dD. Also, the first cable connector groove height ccoH1 may be less than a second cable connector groove height ccoH2 of FIG. 7A by a height difference dH. In addition, the first cable connector groove width ccoW1 may be less than a second cable connector groove width ccoW2 of FIG. 7A by a width difference dW. Accordingly, the upper coupling surface of the multi connector grip 400 may have a structure that matches the first cable connector 221. The lower coupling surface of the multi connector grip 400, which overlaps the upper coupling surface in the vertical direction (i.e., the Z-axis direction), may include a second cable connector groove 422 and a second cable groove 421.

Referring to FIG. 6B, the multi connector grip 400 may be coupled to the storage rack 300 such that the upper coupling surface of the multi connector grip 400 is oriented in the (−)Z-axis direction. The first cable connector 221 is located below the multi connector grip 400 (i.e., in the (−)Z-axis direction), and thus, the first cable connector 221 may be prevented from being separated in the (+)Z-axis direction. Specifically, the multi connector grip 400 may be coupled to a portion of the storage rack 300 (e.g., the board 320 in FIG. 3) by a connection member (e.g., a screw) inserted into a connector fixing hole 414. The multi connector grip 400 may include a cable fixing hole 413, and the first cable connector 221 may be fixed inside the multi connector grip 400 by a connection member inserted into the cable fixing hole 413. In a state in which the first cable connector 221 is positioned on a portion of the storage rack 300 (e.g., the board 320 in FIG. 3), the multi connector grip 400 may be coupled onto the first cable connector 221. Accordingly, the first cable connector 221 may be prevented from being separated in the (−)Z-axis direction by the portion of the storage rack 300.

The first cable 211 may be accommodated in the first cable groove 411 of the multi connector grip 400. A width cW1 of the first cable 211 may be less than the first cable groove width coW1. The first cable connector 221 may be gripped in the first cable connector groove 412 of the multi connector grip 400.

In a state in which the first cable connector 221 is gripped, a robot arm 500 may insert a first storage device 101 into a first slot 311. A first storage connector 111 of the first storage device 101 may be connected to the first cable connector 221.

FIGS. 7A and 7B are views illustrating the multi connector grip 400 that grips a second cable connector 222 according to one or more embodiments.

FIG. 7A is a view obtained by rotating the multi connector grip 400 of FIG. 6A by 180 degrees in the X-axis direction. Referring to FIG. 7A, the lower coupling surface of the multi connector grip 400 may have a structure that grips the second cable connector 222.

Specifically, a second cable 212 may be seated in a second cable groove 421 in the lower coupling surface of the multi connector grip 400, and the second cable connector 222 may be gripped in a second cable connector groove 422 in the lower coupling surface.

The second cable groove 421 may be formed in a size to accommodate the second cable 212. Specifically, the second cable groove 421 may have a second cable groove width coW2, a second cable groove depth coD2, and a second cable groove height coH2. The second cable groove depth coD2 may have a value obtained by subtracting a second cable connector groove depth ccoD2 from the total depth tD. The second cable groove width coW2 may be greater than the width of the second cable 212. The second cable groove height coH2 may be greater than the thickness of the second cable 212.

In one or more embodiments, protruding structures may be formed on the lower coupling surface of the multi connector grip 400 at positions corresponding to the dip structures (231 and 232 in FIG. 4B) of the second cable connector 222. Specifically, when the second cable connector 222 is gripped in the second cable connector groove 422, the upper surface of the second cable connector 222 may be in contact with a support surface 415. Therefore, the protruding structures may be formed at positions on the support surface 415 that are in contact with the dip structures (231 and 232 in FIG. 4B) of the second cable connector 222. The protruding structures may be fitted with the dip structures 231 and 232 to strengthen a fixing force between the multi connector grip 400 and the second cable connector 222.

The second cable connector groove 422 may grip the exterior of the second cable connector 222. Specifically, the second cable connector groove 422 may have the second cable connector groove width ccoW2, the second cable connector groove depth ccoD2, and the second cable connector groove height ccoH2. Referring to FIGS. 4A and 4B, the second cable connector groove width ccoW2 may be equal to the second width W2. The second cable connector groove height ccoH2 may be equal to the second height H2. The second cable connector groove depth ccoD2 may be less than the second depth D2. However, embodiments are not limited thereto, and the second cable connector groove depth ccoD2 may be equal to or greater than the second depth D2. Also, the second cable connector groove width ccoW2, the second cable connector groove depth ccoD2, and the second cable connector groove height ccoH2 may be set such that the second cable connector groove 422 grips the exterior of the second cable connector 222.

The second cable connector groove width ccoW2 may be greater than the second cable groove width coW2. The second cable connector 222 is gripped in the second cable connector groove 422, and the second cable 212 is seated in the second cable groove 421. Accordingly, the second cable connector 222 may be prevented from being separated in the Y-axis direction.

Referring to FIGS. 4A, 4B, 6A, and 7A, the second cable connector groove depth ccoD2 may be greater than the first cable connector groove depth ccoD1 of FIG. 6A by the depth difference dD. Also, the second cable connector groove height ccoH2 may be greater than the first cable connector groove height ccoH1 of FIG. 6A by the height difference dH. In addition, the second cable connector groove width ccoW2 may be greater than the first cable connector groove width ccoW1 of FIG. 6A by the width difference dW. Accordingly, the lower coupling surface of the multi connector grip 400 may have a structure that matches the second cable connector 222. The upper coupling surface of the multi connector grip 400, which overlaps the lower coupling surface in the vertical direction (i.e., the Z-axis direction), may include the first cable connector groove 412 and the first cable groove 411.

When the second cable connector 222 is gripped in the fourth cable connector groove 622, the movement restriction wall 623 may prevent the second cable connector 222 from moving in the (−)Y-axis direction.

When the second cable connector 222 is gripped on the rear coupling surface, a portion of a second cable 212 may be seated on the cable groove and the second cable 212 may extend in the (−)Y-axis direction. Therefore, the cable groove width coW may be greater than the width of the second cable 212. The cable groove height coH may be greater than the thickness of the second cable 212.

Referring to FIGS. 4A, 4B, 9A, and 9B, the fourth cable connector groove depth ccoD4 may be greater than the third cable connector groove depth ccoD3 by the depth difference dD.

FIG. 13 is a view illustrating operation of the multi connector grip 700 according to one or more embodiments. FIG. 13 may be described with reference to FIG. 1. Descriptions given with reference to the above drawings are omitted.

Referring to FIG. 13, a storage device 831 may be inserted into a slot 310. For example, the robot arm 500 may identify the slot 310 based on the coordinates of the slot 310 and insert the storage device 831 into the slot 310.

In order to connect a storage connector 841 of the storage device 831 and a second cable connector 861 to each other, a multi connector grip 700 may rise in the Z-axis direction. When the multi connector grip 700 rises in the Z-axis direction, a gripping state formed by the multi connector grip 700 is changed into a releasing state and a first cable connector 851 may move.

When the first cable connector 851 is removed, the second cable connector 861 may move to the slot 310.

FIGS. 14A and 14B are views illustrating a rotatable multi connector grip 900 according to one or more embodiments. FIGS. 14A and 14B may be described with reference to FIG. 1.

Referring to FIG. 14A, a storage device 1100 may be inserted into a slot 1000. For example, a robot arm 500 may insert the storage device 1100 into the slot 1000.

The rotatable multi connector grip 900 may include a plurality of cable connectors 910 and a plurality of cables 920 connected to the plurality of cable connectors 910.

When the storage device 1100 is inserted into the slot 1000, the rotatable multi connector grip 900 may be rotated so that a required cable connector is connected to a storage connector of the storage device 1100. Unlike the multi connector grips 400, 600, and 700 described above with reference to FIGS. 1 to 13, no time is required to fix the cable connectors 910 to the slot 1000, and thus, test operations may be performed quickly.

Referring to FIG. 14B, the rotatable multi connector grip 900 may rotate in a first rotation direction R1 or a second rotation direction R2. The rotatable multi connector grip 900 may include the plurality of cable connectors 910. For example, first to tenth ports may be provided and the first to tenth ports may support different form factors. That is, the first to tenth ports may have the same pin map, but the exterior specifications of cable connectors may be different from each other.

A cable connector 910, located at a specific position, among the cable connectors 910 included in the rotatable multi connector grip 900 may be connected to the storage connector of the storage device 1100. For example, the cable connector located at 3 o'clock may be connected to the storage connector. Therefore, when the storage device 1100 is inserted, the rotatable multi connector grip 900 may rotate in the first rotation direction R1 or the second rotation direction R2 so that the storage connector and the cable connector optimized for the signal to be evaluated are connected to each other.

The first to tenth ports are connected to respective cables, and thus, entanglement between the cables may occur when the rotation angle increases. When the first to fifth ports are selected as optimized cable connectors, the rotatable multi connector grip 900 may rotate in the second rotation direction R2. Also, when the sixth to tenth ports are selected as optimized cable connectors, the rotatable multi connector grip 900 may rotate in the first rotation direction R1. Accordingly, the entanglement between the cables may be minimized. In some embodiments, the storage device testing system may include a plurality of multi connector grips, and each of the plurality of multi connector grips may correspond to any one of the multi connector grip 400 described above with reference to FIGS. 1 to 7B, the multi connector grip 600 described above with reference to FIGS. 8 to 10B, the multi connector grip 700 described above with reference to FIGS. 11 to 13, and the multi connector grip 900 described above with reference to FIGS. 14A to 14B. For example, the storage device testing system may include a first multiple connector grip and a second multiple connector grip, the first cable connector and a first storage connector may be connected to each other at a first coupling surface of the first multiple connector grip, and the second cable connector and a second storage connector may be connected to each other at a second coupling surface of the second multiple connector grip, the first coupling surface of the first multi connector grip and the second coupling surface of the second multi connector grip may have different structures, a third coupling surface of the first multi connector grip and the second coupling surface of the second multi connector grip may have the same structure, and a fourth coupling surface of the second multi connector grip and the first coupling surface of the first multi connector grip may have the same structure. Moreover, in one embodiment, differences between depths, heights, or widths of a plurality of cable connector grooves corresponding to a plurality of cable connectors may be equal to differences between the depths, the heights, or the widths of the plurality of cable connectors, respectively.
