DETAILED DESCRIPTION

[0037] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0038] According to one embodiment of the present disclosure, the present utility model provides a dual-board functional test fixture 1. Figure 1-7 As shown, a dual-board functional test fixture 1 includes a fixture body 2, the fixture body 2 includes an upper mold frame 21 and a lower mold frame plate 22 that can be opened and closed, and also includes a dual-board needle implant module 3, the dual-board needle implant module 3 includes:

[0039] A carrier board 31, the carrier board 31 is used to carry the first motherboard to be tested 4 and the second motherboard to be tested 5;

[0040] A first test pin board 32 is installed between the carrier board 31 and the lower mold frame board 22 and is provided with a plurality of lower mold planting pins. These lower mold planting pins are used to pass through the pinholes 311 on the carrier board 31 to abut against the test points of the first and second test motherboards 4 and 5;

[0041] The second test needle plate 33 is installed on the upper mold frame 21. The second test needle plate 33 is provided with a plurality of upper mold planting needles, which are used to abut against the test points of the first motherboard to be tested 4 and the second motherboard to be tested 5.

[0042] like Figure 1-6 As shown, the upper mold frame 21 is a frame structure with openings on both the top and bottom surfaces and a hollow interior, and the lower mold frame plate 22 is a plate-like structure with an opening in the middle. The upper mold frame 21 and the lower mold frame plate 22 are opened or closed by a mounting plate and a rotating shaft.

[0043] Two pinning areas are designed on the first test pin board 32 to accommodate the first and second motherboards under test 4 and 5. These two pinning areas are arranged side by side, and multiple lower mold pins are installed on the pinning areas. The lower mold pins can pass through the pinholes 311 on the carrier board 31 and abut the test points of the first and second motherboards under test 4 and 5. Because the two pinning areas on the first test pin board 32 are seamlessly connected, both motherboards can be tested simultaneously, and the pinning can also accurately and stably test the test points of the motherboards under test.

[0044] The two ends of the first test needle plate 32 and the avoidance needle planting area are installed on the lower mold frame plate 22 by means of fixing parts such as screws; in addition, a guide column 321 is installed on the first test needle plate 32 to avoid the needle planting area, which is used to provide guidance for the installation of the carrier plate 31. A guide groove 312 adapted to the guide column 321 is provided at the corresponding position of the carrier plate 31. The guide groove 312 of the carrier plate 31 is passed through and supported on the guide column 321. The carrier plate 31 is fixedly installed on the first test needle plate 32 by fixing parts such as bolts, and the two are spaced apart. In addition, the first main board 4 to be tested and the second main board 5 to be tested (such as Figure 3 As shown, the first motherboard to be tested 4 and the second motherboard to be tested 5 are simply shown as board structures, and the chips thereon such as CPU are not shown).

[0045] like Figure 3-6As shown, the second test needle plate 33 is fixed to the opening on the bottom surface of the upper mold frame. The second test needle plate 33 is also planned to have two needle planting areas that are compatible with the first main board 4 to be tested and the second main board 5 to be tested. A plurality of upper mold planting needles are installed on the needle planting areas. The surrounding areas of the second test needle plate 33 and the avoidance needle planting area are installed on the upper mold frame 21 through fixing parts. In addition, a guide sleeve 331 that is compatible with the guide column 321 is installed on the avoidance needle planting area of ​​the second test needle plate 33. When the upper mold frame 21 and the lower mold frame plate 22 of the fixture body are closed, the guide sleeve 331 on the second test needle plate 33 is passed through the guide column 321, and the second test needle plate 33 is spaced apart from the carrier plate 31.

[0046] In this application's dual-board functional test fixture 1 (referred to as the "fixture," the same applies hereafter), two sets of test probes are designed into one fixture, allowing for simultaneous testing of two motherboards under test (referred to as the "motherboards"), enabling simultaneous pin implantation and power-on testing of both motherboards, increasing testing efficiency by 50%. Therefore, this fixture can test both single and dual boards, offering greater flexibility.

[0047] In one embodiment, Figure 1-5 As shown, the dual-board functional test fixture of the present application also includes a barcode scanner module 6, which includes:

[0048] A first barcode scanner 61 is mounted on the upper mold frame 21 via a barcode scanner fixing module 7 and is positioned corresponding to the first motherboard to be tested 4;

[0049] The second barcode scanner 62 is mounted on the upper mold frame 21 via the barcode scanner fixing module 7 and is positioned corresponding to the second motherboard to be tested 5;

[0050] The scanner fixing module 7 is configured to simultaneously fix the corresponding scanner and adjust the position of the corresponding scanner relative to the corresponding motherboard under test, so that the corresponding scanner can scan the corresponding motherboard under test. That is, the scanner fixing module corresponding to the first scanner is configured to simultaneously fix the first scanner and adjust the position of the first scanner relative to the first motherboard under test, so that the first scanner can scan the first motherboard under test. The scanner fixing module corresponding to the second scanner is configured to simultaneously fix the second scanner and adjust the position of the second scanner relative to the second motherboard under test, so that the second scanner can scan the second motherboard under test.

[0051] For example, the scanner fixed module 7 includes:

[0052] The module body 71 has a first end slidably mounted on the upper mold frame 21 and a second end formed with a mounting slot 74 for mounting a barcode scanner;

[0053] The magnetic member 73 is installed at the second end of the module body 71 . The magnetic member 73 is used to magnetically fix the barcode scanner in the installation slot 74 .

[0054] Furthermore, the barcode scanner fixing module 7 also includes a fixing member 72, which is threadedly connected to the second end of the module body 71 along the vertical direction. The fixing member 72 is used to fix the barcode scanner in the installation slot 711 in the vertical direction.

[0055] For example, Figure 1 、 Figure 7 As shown, a slide rail 75 is provided along the length of the first end of the module body 71. The slide rail is a long hole-shaped structure. The module body can be slidably installed on the upper mold frame through the slide rail 75 by screws and other fixing parts.

[0056] The barcode scanner fixing module 7 of the present application is mainly fixed to the fixture through fixing parts such as slide rails and screws, and then the barcode scanner is accurately aligned to the scanning area through the adjustable slide rail to realize the scanning function.

[0057] The barcode scanner fixing module can fix two types of barcode scanners by setting fixing parts and magnetic parts, so that the staff can adjust the fixing method of the barcode scanner according to the specifications of the barcode scanner. For example, when a metal barcode scanner or a barcode scanner with too small size is selected, it can be directly fixed with a magnetic part to achieve quick disassembly; when barcode scanners of different sizes are selected, the barcode scanner can be fixed by fixing parts. The barcode scanner can be fine-tuned by setting the slide rail to improve the scanning rate. Therefore, the barcode scanner fixing module of this application can realize the rapid disassembly and replacement of the barcode scanner, as well as the fine-tuning of the position to improve the scanning rate.

[0058] Since the position of the SMT (surface mount technology) laser motherboard barcode on each motherboard test is slightly different each time, the staff needs to disassemble and assemble the barcode scanning equipment. Therefore, in order to achieve quick disassembly and assembly and to accurately obtain the barcode information, this application designs a barcode scanner fixing module. By setting a slide rail at the first end of the module body, the position of the barcode scanner relative to the motherboard can be fine-tuned to improve the scanning rate. In addition, by setting magnetic parts and fixing parts, the staff can quickly disassemble and assemble, and at the same time, multiple sets of fixtures can use one set of barcode scanning devices, saving costs and improving testing efficiency.

[0059] In one embodiment, the first barcode scanner 61 is electrically connected to the first motherboard under test 4 through a first USB interface, and the second barcode scanner 62 is electrically connected to the second motherboard under test 5 through a second USB interface, wherein the first USB interface and the second USB interface are of different types.

[0060] To prevent the scanner from being incorrectly installed during line changes, which could lead to incorrect scanning on the motherboard, the fixture in this application features two USB interfaces. For example, the first USB interface can be a Type A USB 2.0 port, and the second USB interface can be a Type B USB 2.0 port. This prevents the risk of scanner installation errors and improves the fixture's testing efficiency.

[0061] Among them, after the mainboard is turned on, it automatically sends instructions to the corresponding barcode scanner. After the barcode scanner receives the instructions, it starts working. The light source of the barcode scanner is illuminated on the barcode of the mainboard. The barcode scanner converts the optical signal into an analog electrical signal, and then converts it into a digital signal through an analog-to-digital converter and transmits it to the mainboard. The mainboard transmits the digital signal to the background test system. The test system receives the digital signal, analyzes it, and determines the functional test corresponding to the mainboard. Therefore, the fixture design of this application automatically scans to achieve automatic scanning and post-testing by the barcode scanner after the mainboard is turned on.

[0062] In one embodiment, the dual-board functional test fixture of the present application also includes a heat dissipation module 8, which includes multiple heat dissipation components 81. The multiple heat dissipation components 81 are installed on the second test needle board 33 at intervals, and the multiple heat dissipation components 81 are used to dissipate heat for the first motherboard to be tested 4 and the second motherboard to be tested 5.

[0063] For example, the heat sink 81 is a heat sink, which is used to abut against the chips of the first motherboard to be tested and the second motherboard to be tested during testing.

[0064] Furthermore, the heat dissipation module 8 further includes a heat dissipation fan 82, which is mounted on the upper mold frame 21. Specifically, Figure 1-5 As shown, a heat dissipation fan 82 is installed in the opening on the top surface of the upper mold frame 21, and the heat dissipation fan 82 is used to dissipate heat in the heat sink.

[0065] For example, the chip is a miniaturized CPU, GPU, or PCH, and the chip generates heat when working. Therefore, in order to effectively dissipate the heat of the chip, when the upper mold frame and the lower mold frame of the fixture body are closed for testing, the heat sink 81 abuts against the chips of the first motherboard to be tested 4 and the second motherboard to be tested 5.

[0066] In one embodiment, as Figure 8-9 As shown, the present invention further provides a dual-board functional testing device 9 , comprising a base 91 , and also comprising a dual-board functional testing fixture 1 according to any one of the above embodiments, wherein the dual-board functional testing fixture 1 is installed in the base 91 .

[0067] For example, the dual-board functional test equipment of the present application further includes a dual-screen bracket module 92, and the dual-screen bracket module 92 includes:

[0068] A first bracket 921 , which is mounted on the base 91 via a first fixing plate 9211 . The first bracket 921 is used to support a first display screen 923 ;

[0069] The second bracket 922 is mounted on the first bracket 921 via a second fixing plate 9221. The second bracket 922 is used to support the second display screen 924. As can be seen from the figure, the first display screen and the second display screen are staggered in the vertical direction.

[0070] The dual-board functional testing device (hereinafter referred to as the "device") of this application superimposes a first bracket and a second bracket together to form a dual-screen display bracket, thereby enabling compatible use of single and dual screens. When testing a single board, one of the brackets can be removed to form a single-screen display bracket, but the function can still be achieved without removing it. When testing a dual board, the two separate display brackets are superimposed to achieve the dual-screen function.

[0071] This application uses a dual-screen display stand (i.e., a first stand and a second stand) to store the display screen, avoiding having nowhere to put the display screen and causing damage.

[0072] The present application uses the first bracket and the second bracket to realize the independent display of two display screens. The display screen connection wiring scheme is to adopt a milling groove design on the back of the carrier board 31 (such as Figure 6 As shown, a wiring groove 313 is provided on the back of the carrier board 31), which perfectly solves the dual-screen connection problem. The dual screens use independent wiring to avoid people plugging in the wrong place, and prevent the wires from being pressed when the fixture is closed, causing quality problems. This application ensures test stability and pass rate by rationally planning the wire routing. The first bracket and the second bracket of this application adopt a superimposed duplex structure, which solves the problem of placing two display screens with one fixture at the same time. In addition, one set of equipment can be shared by multiple sets of fixtures, improving work efficiency and reducing fixture costs.

[0073] The following is a detailed description of the working process of the device in this application:

[0074] Step 1: The staff can place two motherboards into the fixture at the same time and install the test equipment;

[0075] Step 2: Install the two LCD screens on the brackets respectively;

[0076] Step 3: Install the two barcode scanners to the corresponding positions of the fixture. The scanning area can be fine-tuned according to the barcode position on the mainboard.

[0077] Step 4: The staff presses the power button and the mainboard turns on;

[0078] Step 5: Scanner automatically scans and tests;

[0079] Step 6: After the test is completed, cut off the power supply, open the fixture, remove the test equipment, and take out the motherboard.
