DETAILED DESCRIPTION
[0029] The following is a further detailed description of the present invention in conjunction with specific embodiments:
[0030] In order to achieve the purpose of the utility model, the main power board test tool includes: a bottom box 10, which is integrated with a plurality of voltmeters, a plurality of buttons, and a touch screen 5; a push-pull type quick clamp 12, which is arranged on the top surface of the bottom box 10 through a gantry 11; a downward pressing outer cover 17, the push-pull type quick clamp 12 contacts and presses the top of the downward pressing outer cover 17, and a PCB board assembly 16 is wrapped under the downward pressing outer cover 17, such as Figure 5 As shown, the pressing cover 17 has a hollow hole 22 exposing the PCB assembly 16 ; the anti-electric shock cover 14 covers the hollow hole 22 and is detachably assembled with the top of the pressing cover 17 .

Automatic operation can prevent personnel from making mistakes, and automatic data recording can save time for manual data recording. Data is stored in the touch screen 5 for data tracing to prevent personnel from making mistakes in recording. The equipment automatically judges OK / NG, which is better controlled than manual judgment.
[0032] The beneficial effect of adopting the above technical solution is: this technical solution provides a relatively special and relatively integrated main power board test tooling. Place the main power board to be tested on the bottom box, position it with a push-pull quick clamp, and then the staff will use the wires to make various electrical connections. The anti-electric shock cover can cover the messy wires and improve the electrical insulation and safety of the operation. In addition, various voltmeters are convenient for nearby selective connection and testing, and buttons are convenient for nearby selective connection and control of circuit on-off status. The touch screen is used as an interactive operation, and the test data is saved in the touch screen for data traceability to prevent personnel from recording errors. It is simpler to change manual operation to equipment operation.
[0033] In some other embodiments of the present invention, the side of the anti-electric shock cover 14 is provided with a wire hole 21 , and the wire hole 21 and the hollow hole 22 are used for wires to pass through, and the wires are electrically connected to the PCB assembly 16 .
[0034] The beneficial effects of adopting the above technical solution are: the wire holes and hollow holes provide connection paths for the wires, and the shielding effect is also good.
[0035] like Figure 4 As shown, in other embodiments of the present invention, a pressure needle positioning plate 15 is further provided inside the pressing outer cover 17 , and a plurality of conductive needles are arranged on the pressure needle positioning plate 15 in parallel with each other, and each conductive needle contacts with each contact point on the PCB assembly 16 .
[0036] The beneficial effect of adopting the above technical solution is that the pressure needle positioning plate is more specialized, which can greatly reduce the amount of electrical connection work for each contact point. Because the pressure needle positioning plate only needs to consider alignment and clamping. And this clamping can be achieved with the help of the downward force of the push-pull quick clamp.
[0037] like Figure 3 As shown, in other embodiments of the present invention, a vertical guide column 18 is further provided between the gantry 11 and the bottom box 10 , and a guide sleeve 19 is provided on the top of the downward pressing outer cover 17 , and the vertical guide column 18 movably passes through the guide sleeve 19 .
[0038] The beneficial effect of adopting the above technical solution is that the vertical guide column and the guide sleeve are convenient for providing vertical guidance.
[0039] In some other embodiments of the present invention, the bottom of the push-pull quick clamp 12 is provided with a laterally enlarged locking plate 13 , and the locking plate 13 is in contact with the top of the pressing cover 17 .
[0040] The beneficial effects of adopting the above technical solution are: the contact area of the locking plate is increased and the pressure is reduced.
[0041] In other embodiments of the present invention, there are three voltmeters and each voltmeter has a different voltage detection range.
[0042] In other embodiments of the present invention, the three voltmeters monitor respective ranges of 22.8V to 25.2V, 1.27V to 1.56V, and 280V to 342V.
[0043] Three voltmeters test the main power board voltage of the PCB board assembly 16. The first voltmeter 2 tests the 24V power, ranging from 22.8V to 25.2V; the second voltmeter 3 tests the bus sampling voltage, ranging from 1.27V to 1.56V; the third voltmeter 4 tests the bus voltage, ranging from 280V to 342V.
[0044] In some other embodiments of the present invention, there are four buttons, namely a continue button 6 , a release button 7 , a start button 8 , and an emergency stop button 9 .
[0045] There is one touch screen 5.
[0046] like Figure 1 , Figure 2 As shown, from left to right are the continue button 6, the discharge button 7, the start button 8, and the emergency stop button 9. Among them, the function of the continue button 6 is to press the continue button 6 to proceed to the next step after manual confirmation is required, otherwise it will default to NG and stop at the current step. The function of the discharge button 7 is to discharge the voltage of the main power board through a large resistor. The main power board is energized after the power is cut off. If the voltage is not discharged, it will be very dangerous for people to pick it up directly. The start button 8 starts the entire device. The emergency stop button 9 is used for emergency stop when the device encounters an error. After pressing the emergency stop button 9, the entire device will be powered off to protect the safety of the operator.
[0047] In other embodiments of the present invention, a light bulb 1 is further provided on the bottom box 10 .

[0050] The beneficial effect of adopting the above technical solution is that data can be automatically recorded and exported using a USB flash drive.
[0051] In order to clearly express the internal structure, Figure 4 compared to Figure 2 , Figure 4 The anti-electric shock cover 14 and the push-down cover 17 are hidden.
[0052] At least one pair of handles 20 is disposed on the upper surface of the bottom box 10 .
[0053] The operation is integrated into the PLC, and the touch screen prompts you to test according to the steps without any human error. The data is recorded by touch, and the process data can be recorded to analyze the PCBA problem without human error. The operation is simpler. Previously, one person was required to record and two people were required to operate. The new solution automatically tests and records data, which can save one person. The equipment judges OK / NG to prevent human error, and the judgment standard is unified and there is no dispute. The main function is to use single-phase 220V power supply to test whether the voltage at both ends of P3, M3 / P4, and M4 is within the range.
[0054] The test process is as follows: manually put the control power board (i.e., PCB board assembly 16) into the test machine; input the number; manually press down the outer cover 17; after the outer cover 17 is in place, the touch screen 5 prompts the start button 8; turn on the start button 8; short circuit test; manual confirmation after the short circuit test is passed; power on the power supply; wait for 10 seconds; automatically turn on the slow start; manually observe whether the relay sound is heard; after confirmation, the device loads (if it is not confirmed within 5 seconds, the device will automatically power off); the device discharges; wait for the discharge to be completed; manually take out the PCB board assembly 16; replace the new board. (If there is any improper operation, the power supply can be automatically disconnected by pressing the device emergency stop).
[0055] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
