In the production process of small circuit boards, in order to reduce the maintenance and recall costs caused by quality problems after the product is put on the market, users usually need to use detection devices to detect small circuit boards.

[0003] The small circuit board detection device currently on the market is usually composed of a substrate, a support base, a lifting device, an electrode plate and a control device.

[0047] Working principle: The initial state of the small circuit board detection device before use is that the three first protective plates 14 are located above the top of the operating table 1 without a notch. At this time, the connecting plate 18 and the electric suction plate 19 are located at the top, and the second magnetic suction support plate 51 and the first magnetic suction support plate 47 are located at the front end;

[0048] During the use of the small circuit board detection device:

[0049] Step 1: The user needs to move the undetected circuit board to the first magnetic support plate 47 close to the cleaning assembly 5 through an external device;

[0050] Step 2: Run the driving motor 11 in reverse, so that the first moving plate 13 moves the three first protection plates 14 to the three notches close to the cleaning assembly 5 respectively;

[0051] During the movement of the first protection plate 14, the first tooth plate 10 drives the first gear 16 to rotate, and then the first guide rod 15 drives the first moving block 17, the connecting plate 18 and the electric suction plate 19 to move downward, so that the electric suction plate 19 can move to the object-removing position;

[0052] During the operation of the driving motor 11, its output rod drives the first transmission wheel 12 to rotate, and then the second transmission belt 54 drives the fourth transmission wheel 53 to rotate, and then the worm 52 can rotate, and then the first worm wheel 45 and the second worm wheel 49 can rotate, so that the second moving block 46 and the third guide rod 48 can drive the second moving block 46, the first magnetic support plate 47, the third moving block 50 and the second magnetic support plate 51 to move backward;

[0053] And in the process of the first magnetic support plate 47 approaching the cleaning component 5 moving, the passive plate 41 will be driven to move outward, and then the two second toothed plates 42 can respectively drive the second gear 28 and the third gear 30 to rotate, wherein the rotation of the second gear 28 will cause the threaded rod 27 to drive the third movable plate 31 to move upward, and the rotation of the third gear 30 will cause the push-rotating rod 29 to drive the second transmission wheel 32 to rotate, and then the first transmission belt 33 drives the third transmission wheel 35 to rotate, and then the fourth gear 36 drives the fifth gear 38 to rotate, so that the cleaning wheel 39 can rotate, and then cooperate with the reaction force of the spring 43, so that after the first magnetic support plate 47 leaves the passive plate 41, the third movable plate 31 can be moved downward and the cleaning wheel 39 can be rotated, so that the cleaning wheel 39 can clean the surface of the circuit board placed above the first magnetic support plate 47;

[0054] Step 3: Use the electric suction plate 19 to suction and fix the circuit board below it;

[0055] Step 4: Run the driving motor 11 in the forward direction, so that the first moving plate 13 moves the three first protective plates 14 to the three slots away from the cleaning component 5 respectively, and then according to the equipment operation condition in step 2, the circuit board fixed by the electric suction plate 19 is moved to the first magnetic suction support plate 47 and the second magnetic suction support plate 51 away from the three slots of the cleaning component 5;

[0056] Step 5: Stop the electric suction plate 19 so that the electric suction plate 19 no longer sucks the circuit board, thereby allowing the first magnetic suction support plate 47 and the second magnetic suction support plate 51 to magnetically suck the circuit board;

[0057] Step 6: Run the driving motor 11 in reverse to reset the three first protection plates 14, so as to reset the connecting plate 18, the electric suction plate 19, the first magnetic suction support plate 47 and the second worm gear 49;

[0058] After the reset is completed, through the operation of the cylinder 21, the second movable plate 22 can move downward with the electric measuring rod 23, so that the electric measuring rod 23 can perform circuit detection on the circuit board, and then the surface detector 25 can be operated, so that the surface detector 25 can detect the surface condition of the circuit board, and the external conveying device can be operated to discharge the detected circuit board to the top of a first magnetic support plate 47, and the undetected circuit board can be placed on the top of another first magnetic support plate 47.
