In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] In the prior art, a circuit board test device is usually used to test a circuit board. However, when the circuit board test device is testing the circuit board, it is necessary to first install the circuit board on the circuit board test device, and then drive the circuit board to move to the test station for testing. After the test of the circuit board is completed, the circuit board is driven to move to the unloading station, the tested circuit board is removed, and then the next circuit board to be tested is installed on the circuit board test device, so as to test the next circuit board to be tested. The circuit board test device has a certain working gap during the process of installing and removing the circuit board, and cannot achieve continuous operation of the circuit board test, which greatly reduces the test efficiency. In addition, the existing circuit board test device cannot achieve effective positioning of the circuit board when testing the circuit board, which greatly reduces the reliability of the test. The existing circuit board test device is also not convenient for unloading the circuit board after the test.

[0041] In order to solve the above problems, Figure 1 and Figure 2As shown, the present embodiment provides a circuit board testing device, which includes a rotation drive component 1, a positioning component 2 and a test component 3, wherein the positioning component 2 includes a carrier plate 21 and at least two spaced positioning members 22, the carrier plate 21 is connected to the output end of the rotation drive component 1, the rotation drive component 1 is configured to drive the carrier plate 21 to rotate so that each positioning member 22 switches between a test station and a feed station, each positioning member 22 is movably connected to the carrier plate 21, the positioning member 22 has a positioning position and a release position, and each positioning member 22 can position or release the circuit board, when the positioning member 22 moves to the test station, the positioning member 22 is in the positioning position and positions the circuit board, when the positioning member 22 moves to the feed station, the positioning member 22 is in the release position and releases the circuit board, and the test component 3 is configured to test the circuit board at the test station. The circuit board testing device provided in this embodiment drives the carrier plate 21 to rotate by setting a rotary drive assembly 1, so that each positioning member 22 switches between the test station and the unloading station. When the test assembly 3 tests a circuit board positioned by one of the positioning members 22 and located at the test station, at least one positioning member 22 is located at the unloading station to release the circuit board, so that while the circuit board is being tested, the installation and unloading operations of the circuit boards at the remaining stations are realized, thereby realizing the continuous operation of the circuit board test and improving the test efficiency. In addition, when the positioning member 22 moves to the test station, the positioning member 22 is in the positioning position and positions the circuit board, ensuring the reliability of the test assembly 3 on the circuit board test, and when the positioning member 22 moves to the unloading station, the positioning member 22 is in the release position and releases the circuit board, which is more convenient for unloading the circuit board at the unloading station.

[0042] Optionally, in this embodiment, if Figure 1 and Figure 2 As shown, the positioning assembly 2 includes two positioning members 22 spaced apart from each other on the carrier plate 21. When the rotary drive assembly 1 drives the carrier plate 21 to rotate so that one of the positioning members 22 is at the test station, the other positioning member 22 is just at the unloading station, thereby ensuring that while the circuit board at the test station is being tested, the circuit board at the unloading station is removed, and the next circuit board to be tested is placed at the unloading station. In other embodiments, the specific number of positioning members 22 can be set as required.

[0043] In this embodiment, the circuit board test device further includes a control module (not shown in the figure), a central processing module (not shown in the figure) and a display module (not shown in the figure), wherein the test component 3 includes a voltage acquisition unit and a current acquisition unit, the voltage acquisition unit and the current acquisition unit are both connected to the control module in communication, the voltage acquisition unit and the current acquisition unit are both connected to the central processing module in communication, the central processing module is connected to the display module in communication, the control module controls the voltage acquisition unit to acquire the voltage signal of the circuit board, the control module controls the current acquisition unit to acquire the current signal of the circuit board, the voltage acquisition unit and the current acquisition unit can both transmit the acquired signal to the central processing module for processing and analysis, and the central processing module transmits the analysis result to the display module for display, so as to feedback the test result of the circuit board. Since the specific structure and working principle of the test component 3, the control module, the central processing module and the display module belong to the prior art, they will not be described in detail here.

[0044] In this embodiment, if Figure 1 As shown, the rotary drive assembly 1 includes a rotary motor 11 and a transmission rod 12 . The output shaft of the rotary motor 11 is connected to the transmission rod 12 . The transmission rod 12 is connected to the supporting plate 21 . The rotary motor 11 drives the supporting plate 21 to rotate via the transmission rod 12 .

By installing the rotating motor 11 in the mounting groove 51, the structure of the entire circuit board testing device is made more compact, and the protection of the rotating motor 11 is also improved.

[0046] In this embodiment, if Figure 1 As shown, the circuit board testing device also includes a mounting frame 7 and a lifting drive assembly 6, wherein the mounting frame 7 is arranged on the top of the workbench 5, the lifting drive assembly 6 is installed on the mounting frame 7, the test assembly 3 is located above the positioning assembly 2, and the output end of the lifting drive assembly 6 is connected to the test assembly 3, and the lifting drive assembly 6 is used to drive the test assembly 3 to move up and down. When the test assembly 3 tests the circuit board in the test station, the lifting drive assembly 6 drives the test assembly 3 to descend so that the test assembly 3 is docked with the circuit board. When the test assembly 3 completes the test of the circuit board, the lifting drive assembly 6 drives the test assembly 3 to rise and reset, thereby ensuring that the rotation drive assembly 1 rotates the carrier plate 21 and realizes the switching of the circuit board station. Specifically, in this embodiment, the lifting drive assembly 6 can be a cylinder.

[0047] In this embodiment, if Figure 2 and Figure 3 As shown, the positioning assembly 2 also includes an elastic member 23, and an elastic member 23 is connected between each positioning member 22 and the carrier plate 21. The elastic member 23 is configured to always have a tendency to drive the corresponding positioning member 22 and move the corresponding positioning member 22 to the release position. The circuit board testing device also includes an abutment assembly 4. When the positioning member 22 moves to the test station, the abutment assembly 4 abuts against the positioning member 22 to move the positioning member 22 to the positioning position. The above arrangement enables that when the rotary drive assembly 1 drives the positioning member 22 to rotate to the test station, the abutment assembly 4 abuts against the positioning member 22, so that the positioning member 22 compresses the elastic member 23 and moves to the positioning position, thereby realizing automatic positioning of the circuit board; when the rotary drive assembly 1 drives the positioning member 22 to rotate from the test station to the feed station, the abutment assembly 4 removes the abutment force on the positioning member 22, and the positioning member 22 automatically resets to the release position under the elastic force of the elastic member 23 to release the circuit board. The above arrangement makes the positioning and release operations of the positioning member 22 on the circuit board simpler and more convenient. Optionally, in this embodiment, the elastic member 23 may be a spring. Optionally, in this embodiment, a plurality of elastic members 23 are arranged between each positioning member 22 and the bearing plate 21 to ensure the reliability of resetting the positioning member 22 .

The above arrangement enables the spacing between the abutment member 42 and the positioning member 22 at the test station to be adjusted by rotating the adjusting screw 41, thereby adjusting the abutment driving amount of the abutment member 42 on the positioning member 22, and adjusting the movement amount of the positioning member 22 relative to the carrier plate 21, so that the positioning member 22 can position circuit boards of different positions and different models.

[0049] In this embodiment, if Figure 1 and Figure 2 As shown, the abutment assembly 4 also includes an adjustment knob 43, which is fixedly connected to the end of the adjustment screw 41. By setting the adjustment knob 43, the adjustment screw 41 can be driven to rotate relative to the workbench 5 by screwing the adjustment knob 43, making it more convenient and labor-saving to adjust the position of the abutment member 42.

[0050] Optionally, in this embodiment, if Figure 3 and Figure 4As shown, the abutment member 42 includes an adjustment block 421 and an abutment column 422, wherein the adjustment block 421 is threadedly connected to the adjustment screw 41, the abutment column 422 is fixedly arranged on the adjustment block 421, and the positioning member 22 is provided with an arcuate abutment surface 2221, and the outer peripheral wall of the abutment column 422 abuts against the arcuate abutment surface 2221 of the positioning member 22 in the test station. By making the outer peripheral wall of the abutment column 422 abut against the arcuate abutment surface 2221 of the positioning member 22, the abutment between the abutment column 422 and the positioning member 22 is made more stable and reliable, and the abutment drive of the abutment column 422 to the positioning member 22 is made smoother. In addition, by making the outer peripheral wall of the abutment column 422 abut against the arcuate abutment surface 2221 of the positioning member 22, it is also convenient to adjust the displacement amount driven by the abutment column 422 to the positioning member 22.

[0051] In this embodiment, the workbench 5 is provided with an escape slot 52, which extends in the front-rear direction, and one end of the adjusting screw 41 extends into the escape slot 52. The end of the adjusting screw 41 extending out of the escape slot 52 is fixedly connected with the adjusting knob 43, and the adjusting block 421 is slidably connected with the slot wall of the escape slot 52. The escape slot 52 is provided to accommodate the adjusting block 421, which not only makes the structure more compact and reasonable, but also provides a guide for the movement and adjustment of the adjusting block 421.

The positioning member 22 positions the circuit board in the accommodating groove 211, thereby ensuring the reliability of the positioning of the circuit board. In addition, by accommodating the circuit board in the accommodating groove 211, even if the positioning member 22 is in the release position to release the circuit board, the circuit board will not fall out of the accommodating groove 211 during the rotation of the carrier plate 21, thereby ensuring the reliability of the circuit board bearing drive. It should be noted that, in this embodiment, two accommodating grooves 211 are provided on the carrier plate 21 at intervals. In other embodiments, the specific number of the receiving grooves 211 can be set according to requirements, as long as each receiving groove 211 corresponds to each positioning member 22 one by one.

[0053] In this embodiment, if Figure 3 and Figure 4As shown, the first end of the positioning member 22 is provided with a first buffer pad 2211, and the groove wall of the accommodating groove 211 is provided with a second buffer pad 2112. The first buffer pad 2211 and the second buffer pad 2112 are arranged opposite to each other. When the positioning member 22 is in the positioning position, the opposite sides of the circuit board are respectively in contact with the first buffer pad 2211 and the second buffer pad 2112. By making the first buffer pad 2211 and the second buffer pad 2112 in contact with the circuit board, a certain buffering effect is provided for the clamping and positioning of the circuit board, avoiding rigid contact with the circuit board, and improving the protection of the circuit board.

[0055] In this embodiment, if Figure 4 As shown, a support member 2111 is provided on the bottom wall of the receiving groove 211, and the support member 2111 is used to support the circuit board. By using the support member 2111 to support the circuit board, the circuit board is prevented from being attached to the bottom wall of the receiving groove 211, and it is more convenient to take out the circuit board in the receiving groove 211, thereby realizing the unloading operation of the circuit board.
