[0041] In today's era of information explosion, there are more and more types of electronic products. The most common ones are servers, industrial computers, laptops, PADs, watches, smart phones, phones, TVs, video players (VCD, SVCD, DVD), video recorders, camcorders, radios, recorders, combination speakers, laser players (CD), computers, game consoles, mobile communication products, etc. The most important and core part of these products is the board. All electronic products are inseparable from the board; the manufacturing quality of the board determines whether the hardware system can work normally and the stability of the system operation. With the rapid development of information technology, 5G technology and AI artificial intelligence, electronic products have higher and higher requirements for the precision of boards, and more and more electronic components and chips are integrated on the boards. The reliability requirements of precision boards in actual transportation and use are getting higher and higher, and the vibration test of the board is to verify the seismic resistance of the board during transportation and use. It can be seen that vibration testing is particularly important for boards.
[0042] At present, due to the different designs of different product boards, there are many types of boards, which are divided into motherboards and various PCIE boards, IO boards, etc. There are too many electronic components integrated on the board, so when vibrating, it is necessary to use a fixture to simulate the actual assembly of the board for testing. Because there are too many types, shapes, and fixing methods of boards, many types of fixtures are required, and almost every board requires a special customized fixture.
[0043] Currently, due to the differences in types, shapes, structures, and fixing methods of boards, special fixtures need to be developed for vibration testing of boards. Therefore, fixtures have almost no universality, are frequently produced, waste resources, increase costs, and affect the development cycle of boards.
[0044] To this end, the present application provides a general test fixture, such as Figures 1 to 4 As shown, the universal test fixture includes a base 100 and a sliding member 200. The base 100 is used to connect to the vibration platform, and the base 100 is provided with a first sliding groove 110 and a second sliding groove 120 that intersect each other; one end of the sliding member 200 is slidably matched with the first sliding groove 110 or the second sliding groove 120, and the other end of the sliding member 200 is used to support the board 300 to be tested.
[0045] The universal test fixture is provided with a base 100 to connect the base 100 with the vibration platform. The sliding member 200 is provided so that one end of the sliding member 200 is slidably matched with the first slide groove 110 or the second slide groove 120, and the other end supports the board 300 to be tested. The sliding member 200 slides relative to the first slide groove 110 or the second slide groove 120, thereby adjusting the relative position of the board 300 to be tested and the base 100, and also adjusting the relative position of the board 300 to be tested and the vibration platform, thereby adjusting the vibration test position. The universal test fixture of the present application has universality, can not only support the board 300 to be tested of various types, forms, and fixing methods, but also the sliding member 200 can drive the board 300 to be tested to move, thereby adjusting the relative position of the board 300 to be tested and the vibration platform, and is suitable for various vibration test requirements, reducing production costs.
[0046] In some embodiments, Figure 1 and Figure 2 As shown, the sliding member 200 includes a sliding portion 210, a supporting portion 220 and a connecting portion 230. The sliding portion 210 extends into the first slide groove 110 or the second slide groove 120 and slidably cooperates with the first slide groove 110 or the second slide groove 120. The supporting portion 220 is used to support the board 300 to be tested, and the sliding portion 210 is connected to the supporting portion 220 through the connecting portion 230. The sliding portion 210 is provided to achieve the sliding cooperation between the sliding member 200 and the first slide groove 110 or the sliding member 200 and the second slide groove 120, the board 300 to be tested is supported by the supporting portion 220, and the supporting portion 220 and the sliding portion 210 are connected by the connecting portion 230.
[0047] Specifically, Figures 1 to 3As shown, the first slide groove 110 and / or the second slide groove 120 are in a constricted shape, and the first slide groove 110 and / or the second slide groove 120 include a large end and a small end, the sliding part 210 is located in the large end, and the connecting part 230 is located in the small end. The first slide groove 110 and / or the second slide groove 120 are set to be in a constricted shape. When the sliding member 200 needs to be installed on the first slide groove 110 or the second slide groove 120, the sliding part 210 is extended into the large end, and the connecting part 230 is extended into the small end, so that the sliding part 210 slides relative to the first slide groove 110 or the second slide groove 120, thereby adjusting the relative position of the sliding member 200 and the base 100.
[0048] Specifically, Figures 1 to 3 As shown, the cross section of the first slide groove 110 and / or the second slide groove 120 is in the shape of a gourd hole.
[0049] Specifically, Figures 1 to 3 As shown, the cross-sectional area of the connecting portion 230 along the first direction is smaller than the cross-sectional area of the small end along the first direction, wherein the first direction is the sliding direction of the sliding member 200. The cross-sectional area of the connecting portion 230 along the first direction is defined to be smaller than the cross-sectional area of the small end along the first direction, that is, there is a gap between the side wall of the connecting portion 230 and the inner wall of the small end, so that the connecting portion 230 can slide along the direction defined by the small end.
[0050] In some embodiments, Figures 1 to 3 As shown, the universal test fixture further includes a first locking member, which is used to connect the sliding member 200 and the board to be tested 300. By setting the first locking member to connect the sliding member 200 and the board to be tested 300, the board to be tested 300 is fixed on the sliding member 200, and the relative movement between the sliding member 200 and the board to be tested 300 is limited, thereby improving the installation stability of the board to be tested 300 and improving the test accuracy of the vibration test.
[0051] Specifically, Figures 1 to 3 As shown, a locking hole 221 is provided on the side of the sliding member 200 away from the base 100, and the first locking member is used to pass through the board to be tested 300 and extend into the locking hole 221 to connect the sliding member 200 and the board to be tested 300. By providing the locking hole 221 on the side of the sliding member 200 away from the base 100, that is, providing the locking hole 221 on the support portion 220 away from the connecting portion 230, the first locking member passes through the board to be tested 300 and extends into the locking hole 221 to connect the sliding member 200 and the board to be tested 300.
[0052] More specifically, a locking hole 221 is disposed at the top end of the support portion 220 , and the locking hole 221 is a threaded hole.
[0053] In some embodiments, Figures 1 to 3As shown, the universal test fixture further includes a second locking member, which connects the sliding member 200 and the base 100. By providing the second locking member, when the sliding member 200 slides to the preset position, the sliding member 200 and the base 100 are connected by the second locking member, and the sliding member 200 is fixed on the base 100, so that the relative movement of the sliding member 200 and the base 100 is restricted, thereby improving the installation stability of the sliding member 200 and improving the test accuracy of the vibration test.
[0054] In some embodiments, Figures 1 to 3 As shown, a plurality of first slide grooves 110 and a plurality of second slide grooves 120 are provided, and the plurality of first slide grooves 110 and the plurality of second slide grooves 120 are vertically arranged. A plurality of first slide grooves 110 are arranged in parallel, and a plurality of second slide grooves 120 are arranged in parallel, and the plurality of first slide grooves 110 and the plurality of second slide grooves 120 are vertically corresponding one by one, thereby forming a slide groove structure intersecting vertically and horizontally on the base 100, and the sliding member 200 can slide to any second slide groove 120 through any first slide groove 110, thereby increasing the sliding range of the sliding member 200.
[0055] In some embodiments, Figures 1 to 3 As shown, there are multiple sliding members 200. Multiple sliding members 200 are provided, and the multiple sliding members 200 are all slidably matched with the first sliding groove 110 or the second sliding groove 120, and the multiple sliding members 200 can be connected to the board 300 to be tested, thereby improving the installation stability of the board 300 to be tested.
[0056] It can be understood that there are three situations when multiple sliding members 200 are provided and the multiple sliding members 200 are all slidably matched with the first slide groove 110 or the second slide groove 120. The first situation is that the multiple sliding members 200 are all slidably matched with the first slide groove 110; the second situation is that the multiple sliding members 200 are all slidably matched with the second slide groove 120; the third situation is that the multiple sliding members 200 are partially slidably matched with the first slide groove 110 and partially slidably matched with the second slide groove 120. Because the sliding members 200 can slide on the base 100 to adjust the relative position of the board 300 to be tested and the base 100, the above three situations are all possible.
[0057] The present application also provides a vibration test device, including a vibration platform and any of the above-mentioned universal test fixtures, and a base 100 is connected to the vibration platform. The board 300 to be tested is connected to the sliding member 200 of the universal test fixture, and the base 100 of the universal test fixture is connected to the vibration platform. The vibration platform can provide vibration and test the relevant performance of the board to be tested.
[0058] Specifically, the vibration test device further includes a locking member, and the base 100 of the universal test fixture is connected to the vibration platform through the locking member. The locking member is provided to lock the base 100 of the universal test fixture and the vibration platform to limit the movement of the universal test fixture and the board 300 to be tested during the vibration test. For example, the locking member is a screw, a bolt or a pin.
[0059] Furthermore, the vibration testing device also includes a limit assembly, which includes a sliding rail and a slider that are slidably matched. One of the sliding rail and the slider is installed on the vibration platform, and the other is connected to the base 100. The slider can slide along the sliding rail, thereby adjusting the relative position between the universal test fixture and the vibration platform.
[0060] Furthermore, the vibration test device can also be provided with a rotating assembly so that the universal test fixture can rotate relative to the vibration platform. The universal test fixture can rotate relative to the vibration platform at a preset angle, thereby adjusting the test angle of the board 300 to be tested, thereby increasing the test range.
[0061] For example, in some embodiments, the rotating assembly includes a rotating shaft. In other embodiments, the rotating assembly includes a rotating shaft and a cylinder, the rotating shaft is used to rotatably connect the vibration platform and the base 100, and the piston rod of the cylinder is connected to the base 100, and the cylinder can drive the base 100 to rotate.
[0062] Furthermore, if Figure 4 As shown, the present application also provides a method for using the vibration testing device, including:
[0063] (1) Fix the base 100 of the universal test fixture and the vibration platform together;
[0064] (2) Adjusting the relative position of the sliding member 200 and the base 100 according to different boards;
[0065] (3) Locking the sliding member 200 and the base 100 by means of a second locking member, thereby fixing the sliding member 200 on the base 100;
[0066] (4) Fixing the board 300 to be tested on the supporting portion 220 of the sliding member 200 by means of the first locking member;
[0067] (5) Conduct vibration test according to vibration test requirements.
[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
