After all the copper clad laminates in the supply box 8 are tested, the pressure sensor 21 detects that the quality of the supply box 8 is reduced to the lowest level. At this time, one of the alarms 23 is started to remind the staff. When the copper clad laminates in the collection box 9 are continuously increased, the quality of the collection box 9 will gradually increase. When the pressure sensor 21 detects that the quality of the collection box 9 has increased to a certain extent, the other alarm 23 is started to remind the staff.

[0034] Furthermore, a second gear 24 is fixedly sleeved on the outer wall of the rotating shaft 18, and a third gear 25 is meshed with a side wall of one side of the second gear 24. The third gear 25 is rotatably connected to the inner wall of the shell 4, and a rack 26 is meshed with a side wall of the third gear 25. A counterweight 27 is fixedly connected to the lower surface of the rack 26, and the counterweight 27 is slidably connected to the inner wall of the shell 4; by arranging the second gear 24 and the third gear 25 for use in conjunction with each other, when the second motor 19 is started so that the second motor 19 drives the rotating shaft 18 and the first gear 17 to rotate, the rotating rotating shaft 18 can also drive the second gear 24 to rotate, the rotating second gear 24 can drive the third gear 25 to rotate, and the rotating third gear 25 drives the rack 26 and the counterweight 27 to move.

[0037] Furthermore, a waste box 30 is provided on one side of the detection device body 1; by providing the waste box 30, waste can be received. If the detection is unqualified, after the first motor 10 drives the support rod 3 and the two picking mechanisms to rotate 90 degrees, the picking mechanism that picks up the unqualified copper clad laminate can directly release the unqualified copper clad laminate, so that the unqualified copper clad laminate falls into the waste box 30, so that the unqualified products can be separated by themselves, which is convenient and quick.

[0038] In the present invention, before use, first fill the feed box 8 with copper-clad laminates, then start the support plate 31 away from the detection probe 32, put a copper-clad laminate on the support plate 31, and then perform the detection. After the detection is completed, the support plate 31 moves to the bottom of one of the pickup mechanisms, and then the two push rods 7 are started, so that the two push rods 7 push the pickup mechanism to move downward.

[0040] If the test is qualified, the first motor 10 directly drives the support rod 3 and the two picking mechanisms to rotate 180 degrees. Then, after the two picking mechanisms rotate 180 degrees, the copper clad laminate that has passed the test will rotate to the top of the collection box 9. Then the push rod 7 is started, so that the push rod 7 pushes the copper clad laminate that has passed the test into the collection box 9. Then the picking mechanism releases the copper clad laminate that has passed the test and puts the copper clad laminate that has passed the test into the collection box 9. The push rod 7 is reset. After the push rod 7 is reset, the second motor 19 is started, so that the second motor 1 The driving shaft 18 and the first gear 17 rotate, and the rotating first gear 17 can drive the cross bar 5 to move, and the moving cross bar 5 drives the two picking mechanisms to move, so that one picking mechanism moves to the top of the feeding box 8, and the other picking mechanism moves to the top of the pallet 31, and then the picking mechanism releases the copper clad laminate to be tested, and the copper clad laminate will fall on the pallet 31, completing the loading of the copper clad laminate, and the picking mechanism moved to the top of the feeding box 8 can pick up the copper clad laminate to be tested again, so as to prepare for the next loading;

[0041] If the inspection fails, after the first motor 10 drives the support rod 3 and the two picking mechanisms to rotate 90 degrees, the picking mechanism that picks up the unqualified copper clad laminate can directly release the unqualified copper clad laminate, so that the unqualified copper clad laminate falls into the waste bin 30, so as to separate qualified products from unqualified products;

[0042] When the copper-clad laminates in the feed box 8 are continuously taken out for measurement, the mass in the feed box 8 will gradually decrease. After all the copper-clad laminates in the feed box 8 are detected, the pressure sensor 21 detects that the mass in the feed box 8 is reduced to the lowest level. At this time, one of the alarms 23 is activated to remind the staff. When the copper-clad laminates in the collection box 9 are continuously increased, the mass in the collection box 9 will gradually increase. When the pressure sensor 21 detects that the mass of the collection box 9 increases to a certain level, another alarm 23 is activated to remind the staff.

[0043] When the second motor 19 is started and drives the rotating shaft 18 and the first gear 17 to rotate, the rotating rotating shaft 18 can also drive the second gear 24 to rotate, and the rotating second gear 24 can drive the third gear 25 to rotate. The rotating third gear 25 drives the rack 26 and the counterweight 27 to move. The moving counterweight 27 can balance the weight of the picking mechanism on both sides of the support rod 3 to a certain extent, thereby ensuring the balance of weight on both sides of the support rod 3 and ensuring the stability of the support of the support rod 3.
