[0002] Traditional board-level testing of static converter driver boards or daughterboards involves extending wires from signal input and output points, then connecting these wires to an external power supply and oscilloscope. Soldering wires to measurement points and signal input points carries the risk of secondary damage to the board pads beyond repair, making this method unsuitable for repeated use.

[0003] In the detection of the driver board, test points are connected by probes. For example, Chinese patent 202122500182.7 discloses a fixture for driver board detection, which includes a workbench, the workbench includes a machine and a frame, and the frame is arranged on the machine; a lifting assembly, the lifting assembly is arranged on the machine, and the lifting assembly can move away from or close to the machine; a test board, the test board is arranged on one end of the lifting assembly facing the machine, and an IGBT module is arranged on the side of the test board facing the machine; the lifting assembly can drive the test board toward the machine so that the end of the PIN needle on the IGBT module is in contact with the driver board arranged on the machine.

[0004] For the above-mentioned existing technology, the probe pressure contact method can be used to perform a continuity test on the measurement point, but the relative position of the driver board and the PIN needle cannot be adjusted. When the relative position of the driver board and the PIN needle deviates from each other, it is not easy to adjust them to the correct position, which affects the success rate of the detection. Therefore, how to use a detection tool to adjust the position of the driver board and the PIN needle and achieve contact and continuity is a technical problem that needs to be solved.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] In order to solve the technical problem of how to use a detection tool to detect the static converter drive board without damage, the utility model provides a drive board detection tool, which can realize the non-damage detection of the static converter drive board with a detection tool.

[0032] It should be noted that the drive board detection tooling described in the present invention is used for but not limited to the detection of static converter drive boards. For the sake of convenience, in the present invention, only the application of the drive board detection tooling in the detection of static converter drive boards is used as an example for explanation. The principles of applying the drive board detection tooling in the detection of other types of drive boards are essentially the same as those applied to the static converter drive boards, and will not be elaborated here.

[0033] See also Figure 1-4 ,in, Figure 1 This is a three-dimensional diagram of the structure of a driver board testing tool in one embodiment of the present invention. The driver board testing tool comprises a base 1, a test carrier 2, and a suspension carrier 3. The test carrier 2 is mounted on top of the base 1 and is provided with a plurality of probes 201 extending from bottom to top through the test carrier 2. The number of probes 201 is determined based on the signal input and output points to be tested on the static converter driver board, and they are aligned one-to-one with the corresponding points. The suspension carrier 3 includes a lifting component 31, an XY-axis adjustment component 32 and a suspension frame 33. The lifting component 31 is arranged on the top of the base 1, and its movable end is connected to the XY-axis adjustment component 32, which is used to drive the XY-axis adjustment component 32 to perform lifting and adjustment. The suspension frame 33 is arranged on the movable end of the XY-axis adjustment component 32, and the XY-axis adjustment component 32 is used to drive the suspension frame 33 to adjust its position in the XY plane to adjust the detection point thereon to align with the probe 201 below. The suspension frame 33 is provided with an insertion slot 301 for plugging in the static inverter drive board and facing the detection surface of the static inverter drive board toward the test carrier 2 below.

[0034] In this embodiment, the static converter driver board is inserted into the insertion slot 301 with the test surface facing downward. The XY-axis adjustment assembly 32 can be used to fine-tune the coordinate position when the board surface point is slightly offset to align it with the probe 201 below, thereby preventing the probe 201 from being misplaced. The lifting assembly 31 is used to move the suspension frame 33 downward, prompting the test points on the static converter driver board to press into contact with the probe 201, making the operation quick and convenient.

[0035] In one embodiment, see Figure 1-2 In order to reduce the probability of the probe 201 being skewed when pressed, the test carrier 2 includes a needle plate 21 and a positioning plate 22. The positioning plate 22 is installed on the top of the needle plate 21 through a support rod. Pinholes are opened on the positioning plate 22 and the needle plate 21 for the probe 201 to pass through one by one. Through the setting of the double-layer plate, multi-layer support is provided for the probe 201, thereby improving its vertical upward stability.

[0036] In this embodiment, the bottom end of the probe 201 is first inserted into the pinhole on the pin plate 21, and then passed through the pinhole on the positioning plate 22, and the positioning plate 22 is set between the tops of the four support rods.

[0037] In one embodiment, see Figure 1 A plurality of through openings 202 are provided on the top of the positioning plate 22, which are used to correspond one-to-one with the raised portions of the static converter drive plate and for the raised portions on the static converter drive plate to pass through. The static converter drive plate will be installed with raised structural parts, which are raised downward on the detection surface. According to the position of the raised portion, a corresponding through opening 202 is set, which plays an auxiliary positioning role in the process of its descent, so as to avoid not being able to see the detection point below and making inaccurate judgment on whether the position of the probe 201 is aligned.

[0038] In this embodiment, when the lifting assembly 31 moves the suspension frame 33 downward, whether the position of the probe 201 is aligned is determined based on whether the protrusion of the static converter driving board is inserted into the corresponding opening 202 .

[0039] In one embodiment, see Figure 1-2 The suspension frame 33 includes a transverse frame 331 and a U-shaped frame 332. The transverse frame 331 is arranged on the top of the U-shaped frame 332, and the insertion slot 301 is arranged on the left and right side walls of the U-shaped frame 332. The U-shaped frame 332 can ensure that after the drive board is inserted into it, the detection surface is unobstructed and does not interfere with the pressure contact between the probe 201 and the detection point. The transverse frame 331 is used to position the U-shaped frame 332 and dock with the XY axis adjustment component 32, so as to facilitate the coordinate adjustment of the suspension frame 33 at the geometric center.

[0040] Furthermore, the inner top wall and the inner bottom wall of the insertion slot 301 are both provided with buffer pads to prevent damage to the driving board during insertion and pressing down.

[0041] Furthermore, in order to facilitate the replacement of the suspension frame 33 to match drive boards of different sizes for use, an insert block 302 is provided on the top of the suspension frame 33, and a sleeve 303 is provided at the movable end of the XY-axis adjustment component 32. The insert block 302 is inserted into the inner side of the sleeve 303, and a bolt 304 is inserted on the sleeve 303. The bolt 304 passes through the sleeve 303 and is threadedly connected to the insert block 302. The suspension frame 33 can be replaced by removing the bolt 304 and then pulling out the insert block 302 downward.

[0042] In one embodiment, see Figure 1The XY-axis adjustment component 32 includes an X-axis driving component 321 and a Y-axis driving component 322. The Y-axis driving component 322 is connected to the movable end of the lifting component 31. The X-axis driving component 321 is arranged on the movable end of the Y-axis driving component 322 and forms a ninety-degree angle with the Y-axis driving component 322. The suspension frame 33 is arranged on the movable end of the X-axis driving component 321 to adjust the position of the suspension frame 33 on the XY-axis plane and perform horizontal longitudinal and lateral movement adjustments.

[0043] Among them, in order to facilitate direct manual adjustment, the X-axis driving member 321 may include a first guide seat, a first wire lever, a first slider and a first knob. The first wire lever is rotatably connected to the inner side of the first guide seat, and the first slider is slidably connected to the inner side of the first guide seat and is threadedly connected to the first wire lever. One end of the first wire lever passes through the first guide seat and is connected to the first knob. By rotating the first knob, the first slider can be adjusted to move linearly along the guide seat.

[0044] Furthermore, the Y-axis driving member 322 may include a second guide seat, a second wire lever, a second slider and a second knob. The second wire lever is rotatably connected to the inner side of the second guide seat, the second slider is slidably connected to the inner side of the second guide seat and is threadedly connected to the second wire lever. One end of the second wire lever passes through the second guide seat and is connected to the second knob. By rotating the second knob, the second slider can be adjusted to move linearly along the second guide seat.

[0045] Furthermore, the lifting assembly 31 may include a third guide seat, a third wire lever and a third knob. The third lever is rotatably connected to the inner side of the third guide seat. One end of the third wire lever passes through the third guide seat and is connected to the third knob. The second guide seat is slidably connected to the inner side of the third guide seat and is threadedly connected to the third wire lever. By rotating the third knob, the Y-axis drive member 322 can be adjusted to move up and down along the third guide seat.

[0046] It should be noted that, in addition to the above structures, the X-axis driving member 321, the Y-axis driving member 322 and the lifting assembly 31 may also adopt other structures or devices with linear displacement adjustment functions, which will not be described in detail here.

[0047] In one embodiment, see Figure 3 The bottom end of the probe 201 is provided with a cable for connecting an external power supply and an oscilloscope. The test point on the driver board is introduced into the bottom of the tooling through the cable at the bottom of the probe 201. Then, an external power supply and an oscilloscope are connected at the bottom of the tooling to complete the board-level test of the static converter driver board.

[0048] Furthermore, in order to facilitate the installation, positioning and assembly and disassembly of the test carrier 2, a groove 101 is provided on the top of the base 1, and the test carrier 2 is embedded in the groove 101. The installation position of the test carrier 2 is positioned by the groove 101, and its installation and disassembly are facilitated.

[0049] Furthermore, in order to facilitate the downward insertion of the cable at the bottom of the probe 201 , an opening 102 is formed on the groove 101 for the cable at the bottom of the probe 201 to pass through downward.

[0050] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail: the drive plate is inserted between the two grooves 101 and abutted against the rear side wall of the U-shaped frame 332 to form a positioning, and then the first knob and the second knob are rotated respectively to adjust the position of the suspension frame 33 with the XY axis adjustment component 32, so that the protrusion on the static converter drive plate 4 is aligned with the through opening 202 below, and when the lifting component 31 lowers it, the protrusion is inserted into the through opening 202, thereby realizing the pressure contact between the probe 201 and the test point on the static converter drive plate 4, and then the board-level test can be performed according to the cable led out from the probe 201, the external power supply and the oscilloscope.
