[0002] A PCB, or Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnections. Because it is manufactured using electronic printing techniques, it is called a "printed" circuit board. After production, circuit boards undergo various electrical tests to ensure proper functioning. Testing involves manually connecting the contacts of various test circuits to corresponding contacts on the circuit board, then applying power to determine the board's quality. A search revealed patent application number 202320945121.8, which discloses a circuit board testing device in the field of circuit board testing technology. The device includes a workbench and support frames mounted on both sides of the workbench. Support frames are mounted on both sides of the upper surface of the workbench, and a connecting plate is located in the middle of the support frames. A testing mechanism is mounted on the connecting plate, and a support mechanism is located below the testing mechanism. The testing mechanism includes a pressure plate located below the connecting plate and capable of reciprocating vertically towards the connecting plate. Multiple test probes are mounted on the pressure plate, and a moving rod is mounted on the upper surface of the pressure plate.

[0003] However, in actual use, the applicant found that only one circuit board could be tested at a time, resulting in low testing efficiency. Therefore, we propose a circuit board testing device. Utility Model Content

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A circuit board testing device includes a base 1. An electric push rod 3 is fixedly mounted on the top of the base 1. A lifting plate 2 is fixedly connected to the telescopic end of the electric push rod 3. Guide rods 21 are symmetrically fixedly arranged on the top of the lifting plate 2. The upper ends of the guide rods 21 movably penetrate the upper part of the base 1. Rectangular connecting posts 7 are movably arranged side-by-side at equal intervals on the lifting plate 2. A limit plate 71 is provided at the upper end of the rectangular connecting post 7. A connecting seat 8 is fixedly connected to the lower end of the rectangular connecting post 7. A spring 10 is sleeved on the rectangular connecting post 7. The upper end of the spring 10... The spring 10 abuts against the lifting plate 2, and the lower end of the spring 10 abuts against the connecting seat 8. The spring 10 is designed to allow the test probe 92 to effectively contact the contacts on the circuit board. A circuit board test seat 9 is fixed to the lower part of the connecting seat 8, and the test probe 92 is fixedly installed at the bottom of the circuit board test seat 9. An indicator light 6 is fixedly installed on the seat body 1 on the rear side of each circuit board test seat 9. A circuit board test platform 4 is held on the seat body 1 below the lifting plate 2. The top of the circuit board test platform 4 below each circuit board test seat 9 has an opening for power. The circuit board placement slot 41, with multiple circuit board test seats 9 arranged side by side at equal intervals, allows for simultaneous testing of multiple circuit boards, effectively improving testing efficiency. A controller 5 is fixedly mounted on the front of the seat 1, and the controller 5 is electrically connected to an external power supply via wires. A wiring plug is provided on the rear of the circuit board test seat 9. The electric push rod 3, indicator light 6, and circuit board test seat 9 are electrically connected to the controller 5 via wires. When testing circuit boards, the circuit boards to be tested can be placed one by one in the circuit board placement slot 41 on the circuit board test platform 4. The controller 5 drives the electric push rod 3 to move the lifting plate 2 upward. At this time, the lifting plate 2 moves downward, and under the action of the spring 10, it can move the connecting seat 8 and the circuit board test seat 9 downward together, so that the test probe 92 contacts the contact of the circuit board, allowing multiple circuit boards to be tested simultaneously. During the test, when a circuit board has a fault such as abnormal solder joint, the indicator light 6 on the rear of the circuit board test seat 9 corresponding to the circuit board can emit an indicator light to prompt the tester.

[0022] The bottom of the connecting seat 8 is provided with a T-shaped slide groove 81, and the top of the circuit board test seat 9 is provided with a T-shaped slide block 91. The T-shaped slide groove 81 and the T-shaped slide block 91 are connected and the T-shaped slide block 91 is fixed in the T-shaped slide groove 81 by bolts 82. One end of the bolt 82 is threaded through one side of the connecting seat 8 and abuts against the T-shaped slide block 91. The seat body 1 below the lifting plate 2 is provided with a groove 11. The circuit board test platform 4 is inserted into the groove 11. By loosening the bolts 82, the circuit board test seat 9 can be removed from the bottom of the connecting seat 8 and replaced. The circuit board test seat 9 can also be removed from the groove 11 and replaced. This allows the testing device to adapt to the testing of different types of circuit boards, making it more practical. The circuit board test seat 9 can be removed from the bottom of the connecting seat 8 by loosening the bolts 82 and replaced. The new circuit board test seat 9 is electrically connected to the controller 5 one by one by wires. Then the circuit board test platform 4 is removed from the groove 11 and replaced with a suitable test platform, which can adapt to the testing of different types of circuit boards.

[0023] Working principle: During use, when testing circuit boards, the circuit boards to be tested can be placed one by one into the circuit board placement slots 41 on the circuit board test bench 4. The controller 5 drives the electric push rod 3 to move the lifting plate 2 upward. At this time, the lifting plate 2 moves downward, and under the action of the spring 10, it can move the connecting seat 8 and the circuit board test seat 9 downward together, so that the test probe 92 contacts the contacts of the circuit board. Multiple circuit boards can be tested simultaneously. During the test, when the circuit board has faults such as abnormal solder joints, the indicator light 6 on the back of the circuit board test seat 9 corresponding to the circuit board will emit an indicator light to prompt the tester. The circuit board test seat 9 can be removed from the bottom of the connecting seat 8 by loosening the bolt 82 and replaced. The new circuit board test seat 9 is then electrically connected to the controller 5 one by one through the wire. Then, the circuit board test bench 4 is taken out of the groove 11 and replaced with a suitable test bench, which can adapt to the testing of different models of circuit boards.
