Description

However, during the production process, the circuit boards may have weak solder joints, which are difficult to distinguish through image acquisition. Severe shaking and jittering during transportation can easily cause the device to separate from the board. In addition, severe vibrations during conduction can easily cause damage to the device. Therefore, they need to be tested after production to remove defective circuit boards. Summary of the invention

[0052] The detection mechanism 6 includes an industrial camera fixed on the top inner wall of the detection box 11 , and the industrial camera is electrically connected to the controller 14 .

[0053] Working principle:

[0054] Close the inspection door 12, start the industrial camera through the controller 14 to obtain the image data of the circuit board 315 in real time, and then the controller 14 controls the motor 52 to drive the gear 1 53 to reverse, and the gear 1 53 reverses to meet the one-way gear 2 317 to drive the reciprocating screw 2 316 to rotate, and the reciprocating screw 2 316 rotates to drive the moving plate 2 319 and the rack 2 320 to move, and the rack 2 320 moves to mesh with the gear 3 32, and drives the gear 3 32 and the screw 31 to rotate so that the moving frame 34 and The pressing plate needle 35 moves downward, and contacts with the blank position on the top of the circuit board 315, and continues to move downward to press the circuit board 315 downward, and the circuit board 315 moves downward to push the L-shaped support plate 39, the connecting plate 311, the second spring 312, the fourth guide rod 314, and the limit plate 313 below to move downward, and the L-shaped support plate 39 moves downward to compress the first spring 38, and the connecting point at the bottom of the circuit board 315 contacts with the needle of the connecting needle plate 321, so that the circuit board 315 is electrically connected to the controller 14;

[0055] The controller 14 controls the motor 52 to drive the gear 1 53 to rotate forward. The forward rotation of the gear 1 53 satisfies the direction of the rotation of the one-way gear 1 24 to drive the reciprocating screw 1 23, so that the moving plate 1 26 drives the rack 1 27 to move back and forth. The reciprocating movement of the rack 1 27 causes the gear 2 22 to drive the rotating shaft 1 21 and the mounting plate 28 to swing back and forth. The reciprocating swing of the mounting plate 28 drives the circuit board 315 and other structures above to swing back and forth, simulating the shaking during transportation. During the swinging process, the slope 29 of the mounting plate 28 collides with the top of the L-shaped collision block 48, and the vibration generated by the collision is transmitted to the circuit board 315, simulating the impact of the collision during transportation on the electrical circuit board. The reciprocating screw 1 23 drives the rotating shaft 2 41 and the bevel gear 1 42 to rotate, and the bevel gear 1 42 drives Bevel gear two 45 and reciprocating screw three 44 rotate, and the rotation of reciprocating screw three 44 causes moving block 46 to move. The movement of moving block 46 drives reciprocating screw four 47, one-way gear three 49 and L-shaped collision block 48 to move. The L-shaped collision block 48 moves to change the collision position with mounting plate 28, thereby simulating the impact of collisions at different positions of the electrical appliance on circuit board 315 during transportation. When one-way gear three 49 moves toward rack three 410 and meshes with rack three 410, at this time, the meshing direction of one-way gear three 49 satisfies the direction of driving reciprocating screw four 47 to rotate. Reciprocating screw four 47 drives L-shaped collision block 48 to move toward moving block 46. L-shaped collision block 48 moves laterally to change the collision position with mounting plate 28, thereby realizing multi-position collision.

[0056] During the collision, the industrial camera obtains the status of the components of the circuit board 315, such as damage and falling off, to screen the welding quality of the circuit board 315.
