[0041] Example 3

[0042] See also Figure 5 、 Figure 7 and Figure 8 This embodiment provides a technical solution: a circuit board processing strength detection device, including a clamping part 2, an articulating frame 209 and a pushing frame 211:

[0044] Working principle: First, place the circuit board to be tested between the two clamping blocks 207, and use the motor 103 to drive the bidirectional screw rod 102 to select, thereby driving the two slides 201 to slide and displace, so that the clamping blocks 207 clamp and fix the circuit board, and then use the electric push rod 302 to push the gravity sensor 303 down to make it contact with the circuit board, so that the compressive strength test of the circuit board can be carried out. After the detection part 3 completes the detection operation, the clamping block 207 can be rotated to turn the circuit board over, so that the reverse side of the circuit board can be tested. The inspection operation is performed to improve the inspection efficiency. When turning over, it is necessary to ensure that the two articulating frames 209 are driven by the cylinder 210 and dropped to the bottom to prevent the top of the articulating frames 209 from abutting against the clamping block 207. After the clamping block 207 rotates to turn over the circuit board, the cylinder 210 pushes the push frame 211 up and down to drive the two articulating frames 209 to move up and down so that the top of the articulating frames 209 abuts against the clamping block 207, thereby preventing the clamping block 207 from rotating due to external force when inspecting the circuit board.
