The springs 43 and the abutting block 44 on one side of the clamping plate 41 can perform applicable clamping work on both sides of the circuit board. A lifting stop component 5 is fixed on one side of the top frame 2. The feeding component 1 can convey the circuit board to be detected until it abuts against the bottom side of the lifting stop component 5. Then, the bidirectional driving mechanism 3 can drive the two clamping members 4 to approach each other to achieve the purpose of quickly clamping and positioning the circuit board to be detected on both sides. Then, the lifting mechanism 6 is used to drive the detection component 7 to move downward until it is connected to the circuit board and perform detection work.

A slide bar 34 slidably inserted into the slider 35 is fixed on the top frame 2. One end of the bidirectional lead screw 31 is drivingly connected to a driving motor 32. By driving the bidirectional lead screw 31 by the driving motor 32 and cooperating with the guiding action of the slide bar 34 and the slider 35, the two sliding sleeves 33 can move closer to each other along the slide bar 34, thereby achieving the driving purpose of the two clamping members 4.

Then, the driving motor 32 can drive the bidirectional lead screw 31 to rotate, and with the guiding action of the sliding rod 34 and the slider 35, the two sliding sleeves 33 can move closer to each other along the sliding rod 34, thereby driving the two clamping members 4 to move closer to each other, achieving the purpose of quickly clamping and positioning the circuit board to be detected on both sides. Then, the lifting mechanism 6 drives the detection component 7 to move downward until it is connected to the circuit board and performs detection work. The first slide rail 71 and the second slide rail 72 can flexibly adjust the position of the detection probe 74 at the bottom of the positioning slide seat 73, so that the detection probe 74 can be more accurately connected to the circuit board and perform detection. After the detection work is completed, the electric lifting rod 52 can drive the blocking plate 54 to move upward, the cylinder cooperates with the lifting plate to perform the lifting work of the detection component 7, and the feeding component 1 exports the detected circuit board, completing the purpose of quickly detecting the circuit board.
