Description

Function expansion card test platform

Technical Field

The present invention relates to testing of a function expansion card, and more particularly, to a test platform for a function expansion card.

Background

After the function expansion card, such as a display card, a network card, a sound card, a memory module, etc., is manufactured, a test is performed to confirm that the function expansion card is normal.

The test function expansion card is provided with a mainboard, and the peripheries of the central processing unit, the memory, the hard disk, the power supply and the like are connected with the mainboard, so that the mainboard has the functions of starting and executing the test program to be used as a test system. Then, the function test card is inserted into the expansion slot of the host board, the test system is started, the test program is executed manually or automatically, and whether the function is normal or not is judged according to the output of the function expansion card.

The card edge connector of the function expansion card must be correctly positioned and then inserted into the expansion slot, so that the function expansion card can be correctly connected to the expansion slot. In the prior art, a jig is usually disposed on a robot or other transport mechanism for holding a function expansion card, so that the robot or other transport mechanism can insert the function expansion card into an expansion slot accurately. However, the function expansion card is still manually executed to fix the function expansion card to the jig or to remove the function expansion card from the jig, which affects the testing efficiency.

In addition, some function expansion cards have extra electrical connection operations to be performed. Taking the display card as an example, the display signal connector must be connected to the display signal of the display card, so that the test system can receive the display signal to analyze whether the display card is operating normally. A high performance display card also requires an additional connection to a power source. The additional electrical connection operation still needs to be performed manually, so that the test process is not easy to accelerate.

As shown in fig. 7 and 8, the mechanical clamping jaw 400 includes a jaw base 430, at least one first clamping arm 410, at least one second clamping arm 420, and a linear drive assembly 440. The gripper 430 is connected to the robot 460 and is moved by the robot 460 relative to the susceptor 300. The first clamping arm 410 and the second clamping arm 420 are disposed on the claw seat 430, and at least one of the first clamping arm 410 and the second clamping arm 420 is movable relative to the claw seat 430, and the linear driving assembly 440 is disposed on the claw seat 430 and is configured to drive the movable one of the first clamping arm 410 and the second clamping arm 420, so that the first clamping arm 410 and the second clamping arm 420 approach each other to clamp the function expansion card 2, or move away from each other to release the function expansion card 2. In the embodiment of the present invention, the first and second clamp

arms

410 and 420 are slidably disposed on the claw seat 430. The linear driving assembly 440 includes a first pneumatic cylinder device 441 and a second pneumatic cylinder device 442 respectively connected to the first clamping arm 410 and the second clamping arm 420 for driving the first clamping arm 410 and the second clamping arm 420 to move.

As shown in fig. 7 and 8, the first clamping arm 410 and the second clamping arm 420 may respectively include a

groove

412, 422, and the

grooves

412, 422 of the first clamping arm 410 and the second clamping arm 420 face each other. The

trenches

412, 422 may be configured to be slightly larger than the thickness of the circuit board 22. When the first clamping arm 410 and the second clamping arm 420 clamp the function expansion card 2, the edge of the circuit board 22 can be inserted into the

grooves

412, 422, so that the first clamping arm 410 and the second clamping arm 420 can firmly clamp the function expansion card 2.

As shown in fig. 7, an image recognition device 450, including an illumination unit 452 and an image extraction unit 454, may be further disposed on the claw base 430. The illumination unit 452 may be an annular lamp disposed around the image extraction unit 454 to illuminate the function expansion card 2, and particularly, the function expansion card 2 is illuminated by monochromatic light (e.g., red light), so that different structures on the function expansion card 2 can show obvious contrast. The image capturing unit 454 is configured to capture an image of the function expansion card 2, so that the back end machine 800 can identify the type of the function expansion card 2 according to the image, and thereby determine the positions to be gripped by the first clamping arm 410 and the second clamping arm 420, for example, to prevent the first clamping arm 410 and the second clamping arm 420 from being clamped to the card edge connector 22c, a control signal is sent to control the robot arm 460 to move the mechanical clamping jaw 400 to align the positions suitable for being gripped by the first clamping arm 410 and the second clamping arm 420.

As shown in fig. 9 and fig. 18, the mechanical clamping jaw 400 can move relative to the carrier 300 for gripping the function expansion card 2 from a feeding stage 910 and placing the function expansion card 2 on the carrier 300, or the mechanical clamping jaw 400 can be used for removing the function expansion card 2 from the carrier 300 and placing the function expansion card 2 on a material receiving stage 920.

As shown in fig. 1, fig. 2 and fig. 6, the holding device 500 is connected to the carrying base 300 for pushing the function expansion card 2 in the first direction X and the second direction Y. The holding device 500 includes a first linear driving device 510 and a second linear driving device 520. The first linear driving device 510 is used for pushing the function expansion card 2 toward the expansion slot 32 in the first direction X. The second linear driving device 520 is used for pushing the function expansion card 2 toward the connector assembly 600 in the second direction Y.

As shown in fig. 6, the first linear driving device 510 and the second linear driving device 520 are directly or indirectly disposed on the carriage 300. In one embodiment, the first linear drive device 510 includes a first fixed base 512, a first lead screw 514, a first push block 516, and a first drive assembly 518. The first fixing base 512 and the first driving assembly 518 are directly or indirectly disposed on the supporting base 300. The first lead screw 514 is disposed along the first direction X, and one end of the first lead screw 514 is pivotally connected to the first fixing base 512, and the other end is connected to the first driving assembly 518. Meanwhile, the first pushing block 516 is screwed to the first lead screw 514. By the rotation of the first driving assembly 518, the first lead screw 514 drives the first pushing block 516 to reciprocate, so as to push the function expansion card 2 in the first direction X. Similarly, the second linear driving device 520 includes a second fixed base 522, a second lead screw 524, a second pushing block 526 and a second driving assembly 528. Second lead screw 524 is disposed along second direction Y. In addition, the arrangement among the second fixing base 522, the second lead screw 524, the second pushing block 526 and the second driving assembly 528 is substantially the same as that of the first fixing base 512, the first lead screw 514, the first pushing block 516 and the first driving assembly 518, and will not be described again. By the rotation of the second driving assembly 528, the second lead screw 524 drives the second pushing block 526 to reciprocate, so as to push the function expansion card 2 in the second direction Y.

As shown in fig. 1, fig. 2, fig. 10 and fig. 11, the connector assembly 600 is disposed adjacent to the fixing frame 200, and at least one signal connector 620 is provided and disposed toward the carrier 300 along the second direction Y. The relative position of the signal connector 620 and the carrier 300 matches the relative position of the connection port 24 and the circuit board 22 on the function expansion card 2, and the signal connector 620 can be inserted into the connection port 24 to receive the signal output by the function expansion card 2.

As shown in fig. 10 and 11, the connector assembly 600 includes a base 610 and a plurality of signal connectors 620. The base 610 has a plurality of through holes 612 penetrating through the base 610 along the second direction Y. Each signal connector 620 is disposed in each through hole 612 and selectively moves toward the carrying base 300 along the second direction Y to protrude out of the base 610. Specifically, each signal connector 620 corresponds to a different interface communication standard, and can be matched with the connection port 24 of a different function expansion card 2. Although all the signal connectors 620 are shown to protrude from the base 610 in fig. 10 and 11, in practice, only the signal connector 620 corresponding to the function expansion card 2 needs to protrude from the base 610 in each test operation, and the rest of the signal connectors 620 are kept accommodated in the through holes 612. The technical means for driving the signal connectors 620 to protrude or retract may be, but is not limited to, a linear motor, a pneumatic cylinder, and a solenoid valve.

As shown in fig. 1, 2 and 12, the power supply assembly 700 is disposed on the base 100 and includes a plurality of electrode sets 710. Each electrode group 710 includes a plurality of electrodes arranged in parallel. Each electrode set 710 is selectively moved toward the function expansion card 2 along the first direction X to be inserted into a power socket 26 of the function expansion card 2 to provide additional power to the function expansion card 2. The plurality of electrodes in each electrode set 710 are arranged differently to match different specifications of power outlets 26. In addition, the plurality of electrodes may be configured to be bare and inserted into different holes of the power socket 26, or the plurality of electrodes may be covered by an insulating base (not shown) to form a power plug for connecting to the power socket 26.

The operation of the function expansion card test platform 1 is described below.

As shown in fig. 5, 7 and 9, first, a plurality of function expansion cards 2 to be tested are arranged on a feeding table 910. The rear end machine 800 controls the robot arm 460 to move the mechanical clamping jaw 400 to the feeding table 910 to clamp a function expansion card 2. When the mechanical gripper 400 grips the function expansion card 2, the image extracting unit 454 extracts an image of the function expansion card 2 and transfers the image to the backend station 800. The back end unit 800 determines the positions to be gripped by the first and second gripping arms 410 and 420 (e.g. to avoid gripping the card edge connector 22c) according to the type of the image recognition function expansion card 2, so as to send a control signal to control the robot arm 460 to move the mechanical gripper 400 to the proper position to grip the function expansion card 2.

Next, as shown in fig. 5, fig. 9 and fig. 13, the rear machine 800 controls the robot arm 460 to move the mechanical clamping jaw 400 to the carrier 300, and place the function expansion card 2 on the carrier 300, and align the card edge connector 22c with the expansion slot 32 of the motherboard 3. The motherboard 3 is disposed on the fixing frame 200, and the card edge connector 22c of the function expansion card 2 can be aligned to the expansion slot 32 of the motherboard 3 according to the height of the bearing seat 300.

As shown in fig. 5 and fig. 14, the rear machine 800 controls the first driving assembly 518 of the first linear driving device 510 to rotate, and pushes the functional expansion card 2 toward the expansion slot 32 by the first pushing block 516 in the first direction X, so that the card edge connector 22c is inserted into the expansion slot 32.

As shown in fig. 5, 10, 11 and 15, the rear machine 800 controls the second driving assembly 528 of the second linear driving device 520, and pushes the function expansion card 2 toward the connector assembly 600 in the second direction Y. At the same time, the rear-end machine 800 also controls the axial driving device 630 of the connector assembly 600 to push the seat 610 to move toward the connection port 24 of the function expansion card 2 along the second direction Y, so that the signal connector 620 is inserted into the connection port 24.

As shown in fig. 4, in one embodiment, the fixing frame 200 may be provided with an adapter slot 210 connected to the expansion slot 32 and extending toward the direction of the carrier 300, so that the card edge connector 22c may also be inserted into the adapter slot 210 and indirectly connected to the expansion slot 32.

As shown in fig. 1 and 16, the base 610 of the joint assembly 600 may be disposed on a first multi-axis mobile platform 640. The rear machine 800 can control the first multi-axis moving platform 640 to drive the base 610 to move along the first direction X and the third direction Z according to the geometric specification of the function expansion card 2, so that the positions of the signal connector 620 in the first direction X and the third direction Z can be matched with the position of the connection port 24 of the function expansion card 2, and the signal connector can be smoothly inserted and connected. When a plurality of expansion cards 2 with the same function are tested continuously, the first multi-axis moving platform 640 moves the base 610 to the corresponding positions in the first direction X and the third direction Z only by one actuation, and when the expansion cards 2 with the same function are tested continuously, the first multi-axis moving platform 640 does not need to be actuated again. On the contrary, if the model of the tested function expansion card 2 is changed, the backend machine 800 controls the first multi-axis mobile platform 640 to move the position of the base 610 according to the new geometric specification.

As shown in fig. 1 and 17, when the expansion card 2 needs additional power, such as a high performance graphics card, the expansion card 2 has an additional power socket 26. Different types of power sockets 26 may be configured for different specifications of the function expansion card 2, and the positions of the power sockets 26 are also different. At this time, the back-end tool 800 may select one of the electrode sets 710 of the power supply assembly 700 according to the specification of the power socket 26, so as to control the electrode set 710 to move toward the function expansion card 2 along the first direction X, so as to plug into a power socket 26 of the function expansion card 2, so as to provide additional power to the function expansion card 2. The movement of the electrode group 710 toward the function expansion card 2 along the first direction X is merely exemplary, and the movement direction depends on the shape and position of the power socket 26. The driving means for driving the electrode sets 710 to move may be, but is not limited to, a linear motor, a pneumatic cylinder, and a solenoid valve.

As shown in fig. 1 and 17, the power sockets 26 of the expansion cards 2 with different functions are arranged at different positions, and the sets of electrode groups 710 are arranged adjacently or in a stacked manner. In order to enable the corresponding electrode sets 710 in the power supply assembly 700 to be located at the correct positions in the second direction Y and the third direction Z, the function expansion card testing platform 1 further includes a second multi-axis moving platform 720 disposed on the base 100, and the plurality of electrode sets 710 are disposed on the second multi-axis moving platform 720. The rear-end machine 800 may control the second multi-axis moving platform 720 to move the plurality of sets of electrode sets 710 in the second direction Y and the third direction Z according to the geometric specification of the function expansion card 2, so that the corresponding electrode sets 710 may be aligned with the power socket 26 of the function expansion card 2.

Then, the back end unit 800 may start the power supply, so that the power supply supplies power to the motherboard 3 and/or the function expansion card 2 through the electrode set 710. The back-end console 800 transmits a boot signal to the motherboard 3, so that the motherboard 3 enters a boot program and automatically or manually drives the function expansion card 2 to operate, thereby executing the test program. The testing function expansion card 2 outputs signals through the connection port 24, so that the back-end machine 800 receives the output signals through the signal connector 620 of the connector assembly 600, thereby determining whether the function expansion card 2 is operating normally.
