Description

Technical Field

[0001] This utility model relates to the field of computer graphics card testing technology, specifically a computer graphics card insertion and removal testing device. Background Technology

[0002] As a crucial component of a computer system, the graphics card is responsible for converting internal computer data into image signals and displaying them to the user through a monitor. With the rapid development of technology, graphics cards have made significant progress in performance, functionality, and application areas. The graphics card interface refers to the connection method between the graphics card and the motherboard or other devices. Different interface types and connection methods will affect the performance and stability of the graphics card. Currently, the main types of computer graphics card interfaces are: ISA, PCI, AGP, and PCI Express (PCIe). Among them, the ISA interface has been gradually phased out, while the PCIe interface is currently the most common and advanced graphics card interface. During the production process of computer graphics cards, sampling and plug-in / plug-out tests are required to detect the performance of the computer graphics card.

[0003] A search revealed that CN223050853U discloses a computer graphics card insertion / removal testing device, comprising a base with a limiting block installed at the top center of the base. When one end of the connecting rod rotates along the outside of the turntable, it drives a movable push rod to reciprocate on the limiting block, thereby causing repeated insertion and removal of the computer graphics card for testing. Rotating the adjusting bolt causes the pressing plate to descend, limiting and fixing computer graphics cards of different sizes. When the triangular block moves, it simultaneously squeezes the reset spring and drives the limiting rod to move and engage with the limiting hole, facilitating the replacement of sockets of different sizes. This effectively solves the problem that traditional graphics card insertion / removal testing devices are inconvenient for testing computer graphics cards of different sizes and models, resulting in low practicality.

[0004] The aforementioned technology discloses a computer graphics card insertion / removal testing device. This device uses a rotating drive dial to rotate, which in turn drives a connecting rod to control a movable push rod to move back and forth to the right and left, thus causing the clamped computer graphics card to move back and forth to continuously insert and remove from the graphics card socket. However, in actual use, it has the following shortcomings: 1. Because the opposing sides of the computer graphics card and the graphics card socket are blocked and restricted by the mounting plate and protrusions respectively, and the distance of the rotating dial's full rotation is fixed, it is difficult to adapt to the insertion / removal testing of computer graphics cards of different widths. When the computer graphics card is wide, relative collision damage is likely to occur, resulting in poor applicability; 2. It lacks a counting mechanism during testing, making it difficult to accurately control the number of insertions and removals. Therefore, this application proposes a computer graphics card insertion / removal testing device to solve the above-mentioned problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figures 1 to 2 As shown in this embodiment, a computer graphics card insertion / removal testing device includes:

[0031] The base 1 has a protective cover 101 with openings on the left side, bottom and front side fixedly connected to its top;

[0032] The PLC controller 2 is fixedly installed on the top inner wall of the shield 101, and a display electrically connected to the PLC controller 2 is fixedly installed on the top inner wall of the shield 101.

[0033] The U-shaped support 306 consists of two sets, both of which are installed inside the shield 101. The bottom of the U-shaped support 306 on the left side is fixedly connected to the top of the base 1 with a fixing seat 3. A clearance through hole 102 with an open front is provided on the inner wall of the right side of the shield 101. The clearance through hole 102 is located on the right side of the U-shaped support 306. The two U-shaped support 306 are used to place the plugged-in computer graphics card and graphics card socket.

[0034] The reciprocating horizontal guide drive assembly is fixedly connected between the right side of the fixed base 3 and the right side U-shaped support 306, and is electrically connected to the PLC controller 2; the reciprocating horizontal guide drive assembly is used to drive the right side U-shaped support 306 to move back and forth to the right and left.

[0035] The pressure block 4 consists of two sets, which are respectively set in the corresponding U-shaped support 306. The bottom of the pressure block 4 is glued and fixed with anti-slip rubber 401.

[0036] The vertical drive assembly consists of two sets, each mounted on a corresponding U-shaped support 306. The two vertical drive assemblies are connected to the top of the corresponding pressure block 4. The vertical drive assembly is used to drive the two pressure blocks 4 to move vertically, thereby pressing the computer graphics card and the graphics card socket firmly. When the U-shaped support 306 on the right side moves back and forth to the right and left, it drives the computer graphics card to move back and forth to the right and left, so that it can perform a back and forth insertion and removal test with the graphics card socket.

[0037] Furthermore, such as Figure 1 and 2 As shown, the reciprocating horizontal guide drive assembly includes four horizontal guide rods 302, a support base 305, a reciprocating lead screw 303, a movable base 301, a drive motor 304, and a tactile switch 201. The support base 305 is fixedly installed on the top right side of the base 1. The four horizontal guide rods 302 are rectangularly fixedly connected between the right side of the fixed base 3 and the left side of the support base 305. The movable base 301 is slidably sleeved on the four horizontal guide rods 302. The drive motor 304 is fixedly installed on the right side of the support base 305. The reciprocating lead screw 303 is fixedly connected to the left end of the output shaft of the drive motor 304 through a coupling. The movable base 301 is threaded onto the reciprocating lead screw 303. The tactile switch 201 is fixedly connected to the top of the base 1. The actuating end of the tactile switch 201 is in active contact with the bottom left side of the movable base 301. The tactile switch 201 and the drive motor 304 are both electrically connected to the PLC controller 2. The movable base 301 is fixedly installed on the right side of the U-shaped support 306.

[0038] In this embodiment, the right side of the movable seat 301 is provided with a reciprocating screw hole that is threadedly connected to the reciprocating screw 303. The threaded connection between the reciprocating screw 303 and the reciprocating screw hole facilitates the reciprocating right and left movement of the movable seat 301 when the reciprocating screw 303 rotates. The right side of the movable seat 301 is provided with four horizontal guide holes that are slidably fitted onto the outer side of the corresponding horizontal guide rods 302, which serve to guide the lateral sliding of the movable seat 301. A support plate is fixedly connected between the four horizontal guide rods 302. A first bearing is fixedly connected to the right side of the support plate. A rotating shaft is fixedly fitted inside the inner ring of the first bearing. The right end of the rotating shaft is fixedly connected to the left end of the reciprocating screw 303, which serves to rotatably install the reciprocating screw 303.

[0039] In this embodiment, four horizontal guide rods 302, support base 305, reciprocating screw 303, moving base 301, drive motor 304, and tactile switch 201 work together. The drive motor 304 drives the reciprocating screw 303 to rotate. The rotation of the reciprocating screw 303 causes the moving base 301 to slide back and forth on the four horizontal guide rods 302. The moving base 301 drives the U-shaped support 306 on the right side to move back and forth on the right and left. Each time the moving base 301 moves back and forth on the right and left, it presses and actuates the tactile switch 201. Each time the tactile switch 201 is actuated, it connects the circuit. When the PLC controller 2 detects a voltage signal, it recognizes it as a triggered state, counts the signals, and controls the display to show the quantity.

[0040] Furthermore, such as Figure 1 and 2 As shown, the vertical drive assembly includes four vertical guide rods 403 and a T-shaped screw 402. The top of the pressure block 4 is fixedly connected to the bottom of the corresponding four vertical guide rods 403. The U-shaped support 306 is slidably sleeved on the corresponding four vertical guide rods 403. The T-shaped screw 402 is rotatably installed on the top of the corresponding pressure block 4. The U-shaped support 306 is threadedly sleeved on the corresponding T-shaped screw 402.

[0041] In this embodiment, the top of the U-shaped support 306 is provided with a threaded hole that is threadedly connected to the corresponding T-shaped screw 402. The threaded connection between the T-shaped screw 402 and the threaded hole facilitates the upward and downward displacement of the T-shaped screw 402 during rotation. The top of the U-shaped support 306 is rectangular and has four vertical guide holes that slide and fit with the outer side of the corresponding vertical guide rod 403, thus guiding the vertical sliding of the vertical guide rod 403. The top of the pressure block 4 is fixedly connected to a second bearing, and the inner side of the inner ring of the second bearing is fixedly connected to the outer side of the corresponding T-shaped screw 402, thus enabling the rotational installation of the T-shaped screw 402.

[0042] In this implementation scheme, four vertical guide rods 403 and T-shaped screws 402 cooperate to rotate two T-shaped screws 402 in the forward direction, causing them to rotate and move downward within the corresponding U-shaped support 306. The T-shaped screws 402 drive the corresponding pressure blocks 4 to move downward, and the pressure blocks 4 drive the four vertical guide rods 403 to slide downward within the U-shaped support 306 to perform vertical guiding work. The downward movement of the two pressure blocks 4 drives the two anti-slip rubber sheets 401 to press and fix the computer graphics card and graphics card socket respectively. Through pressing, when the U-shaped support 306 on the right side moves back and forth to the right and left, it can drive the pressed computer graphics card to move back and forth to the right and left to perform continuous plug-in and unplugging tests. Each cycle of movement counts the plug-in and unplugging. When the preset number of tests is reached, the PLC controller 2 controls the drive motor 304 to shut down, realizing the effect of automatically testing, counting and displaying the number of plug-in and unplugging of the computer graphics card.

[0043] This embodiment facilitates the placement and fixation of computer graphics cards and graphics card sockets of different widths and lengths through a side opening that protrudes outwards. This avoids damage caused by the excessive width of the computer graphics card during plug-in / plug-out testing due to collisions, thus improving applicability and safety. It also facilitates the reciprocating lateral movement of the computer graphics card for plug-in / plug-out testing, counting and displaying the number of plug-in / plug-out attempts. Furthermore, it can automatically stop the plug-in / plug-out testing when a preset count is reached, achieving automatic and precise control over the number of plug-in / plug-out attempts, further improving ease of use and testing accuracy.

[0044] The usage method of this embodiment is as follows: When using the computer graphics card insertion and removal testing device, firstly, insert the computer graphics card and graphics card socket to be tested into each other. Then, start the drive motor 304 to drive the reciprocating screw 303 to rotate. The rotation of the reciprocating screw 303 causes the moving seat 301 to move laterally back and forth. When the moving seat 301 moves to the leftmost position and presses the tactile switch 201, the operator turns off the drive motor 304 and sets this position as the initial position. Place the inserted computer graphics card and graphics card socket on the bottom inner wall of the two U-shaped support seats 306 respectively. Since the front of the U-shaped support seat 306 is open, it will not form an obstruction, making it convenient to place computer graphics cards and graphics card sockets of different lengths in the front and back directions. After placement, rotate the two T-shaped screws 402 in the forward direction so that they rotate and move downward in the threaded holes on the corresponding U-shaped support seats 306. The T-shaped screw 402 drives the corresponding pressure block 4 to move downwards. The pressure block 4 drives the four corresponding vertical guide rods 403 to slide downwards within the U-shaped support 306 to perform vertical guiding work. The downward movement of the two pressure blocks 4 drives the two anti-slip rubber sheets 401 to press and fix the computer graphics card and graphics card socket respectively, thereby achieving the effect of fixing the computer graphics card and graphics card socket. In addition, taking advantage of the characteristics of the shape of the two U-shaped support 306, both sides are open, so they will not obstruct or restrict the computer graphics card and graphics card socket in the left and right width direction. When the computer graphics card and graphics card socket are wide, the opposing sides of the two can be protruded out of the corresponding U-shaped support 306 respectively, so as to facilitate the placement and fixing of computer graphics cards and graphics card sockets of different widths. This avoids the phenomenon of collision damage during plugging and unplugging tests due to the computer graphics card being too wide under a certain horizontal movement distance, thus improving applicability and safety.

[0045] The PLC controller 2 is pre-set to control the number of times the drive motor 304 is turned off. The drive motor 304 is then started, causing the reciprocating screw 303 to rotate. The rotation of the reciprocating screw 303 causes the movable seat 301 to slide back and forth on the four horizontal guide rods 302. The movable seat 301 then drives the right-side U-shaped support 306 to move back and forth on the right and left. The right-side U-shaped support 306 then drives the pressed computer graphics card to move back and forth on the right and left, performing a continuous insertion and removal test. Each time the movable seat 301 moves back and forth one stroke, it presses and actuates the tactile switch 201. Each time the circuit 201 is activated, the PLC controller 2 detects a voltage signal and identifies it as a triggered state. It then counts the number of insertions and removals and controls the display to show the count. Each cycle of movement counts the insertions and removals. When the preset number of tests is reached, the PLC controller 2 controls the drive motor 304 to shut down. This achieves the effect of automatically testing, counting, and displaying the number of insertions and removals of the computer graphics card. It can also automatically stop the insertion and removal test when the preset number of counts is reached, achieving automatic and precise control of the number of insertions and removals, further improving ease of use and accuracy of testing.

[0046] Example 2

[0047] like Figure 3 As shown, this embodiment differs from Embodiment 1 in that the vertical drive assembly includes an electric telescopic rod 404 and a pressure sensor 405. The electric telescopic rod 404 is fixedly installed on the top of the corresponding U-shaped support 306, and the extended end of the electric telescopic rod 404 extends into the corresponding U-shaped support 306. The pressure sensor 405 is fixedly installed between the extended end of the electric telescopic rod 404 and the top of the pressure block 4. Both the electric telescopic rod 404 and the pressure sensor 405 are electrically connected to the PLC controller 2.

[0048] This embodiment can quickly and automatically drive the two pressure blocks 4 to precisely control and fix the computer graphics card and graphics card socket respectively. By using the automatic pressure control method formed by pressure measurement, it avoids the phenomenon of excessive pressure causing damage to the computer graphics card or graphics card socket. Compared with the manual rotation and fixing method, it improves the fixing efficiency and pressure control accuracy.

[0049] The usage method of this embodiment differs from that of Embodiment 1 in that it has the following functions: Utilizing the electric telescopic rod 404 and pressure sensor 405, the PLC controller 2 pre-sets the pressure value of the electric telescopic rod 404. When the computer graphics card and graphics card socket are placed and need to be pressed, the electric telescopic rod 404 is activated in the forward direction, causing it to move the pressure block 4 downwards via the corresponding pressure sensor 405 to perform the pressing work. During pressing, the pressure sensor 405 detects the downward squeezing force applied by the corresponding electric telescopic rod 404 and converts it into a standard electrical signal, which is then transmitted to the PLC controller 2. The PLC controller 2 converts the received standard electrical signal into an actual pressure value through analog-to-digital conversion. When the preset pressure value is reached, the PLC controller 2 controls the electric telescopic rod 404 to close, achieving the effect of quickly and automatically driving the two pressure blocks 4 to precisely control and fix the computer graphics card and graphics card socket. This automatic pressure control method, based on pressure measurement, avoids damage to the computer graphics card or graphics card socket due to excessive pressure, improving fixing efficiency and pressure control accuracy.

[0050] It should be noted that the PLC controller 2 preferably adopts a Siemens S7-200SMART programmable controller with an integrated analog input module. This type of controller can directly receive the standard electrical signal output by the pressure sensor 405 and accurately convert the electrical signal into the actual pressure value through its integrated analog-to-digital conversion function, ensuring the accuracy of data acquisition. The pressure sensor 405 preferably adopts a Transcell BSS series plate (pressure) load cell, whose structural design and measurement accuracy can meet the device's requirements for pressure parameter detection.

[0051] Regarding the connection method of the tactile switch 201, its two ends are respectively connected to the input point (such as I0.0) of the PLC controller 2 and the negative terminal of the external power supply through wires. When the tactile switch 201 is pressed and triggered to close, causing the circuit to be connected, the input point of the PLC controller 2 can detect the voltage signal and identify it as a "trigger state" to perform trigger counting according to the programming program. In addition, the drive motor 304 and the electric telescopic rod 404 are both connected to the PLC controller 2 through wires and relays to form an electrical connection controlled by the PLC controller 2. This connection method belongs to the conventional wire control technology of programmable controllers and is a mature and well-known technical means in the industry, so it will not be described in detail here.

[0052] Regarding power supply, given the factory environment at the computer graphics card insertion and removal test site, the power supply facilities are complete and the power supply conditions are sufficient. All electrical components of this device are connected to the on-site mains power. They are connected to the power input interfaces of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete and stable power supply circuit. This power supply scheme conforms to the conventional power distribution standards for industrial equipment and is a mature and well-known technical means, so it will not be described in detail here.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
