The conductive clips 63 and the solenoid valve of the cylinder 61 are electrically connected to the PLC controller 78. The cylinder 61 causes the movable plate 62 to descend, so that the conductive clips 63 clamp the conductive lead-out terminals of the product, and cooperate with the conductive socket 51 to enable the resistance tester 71 and the insulation resistance tester 7271 to measure the conductive lead-out terminals at both ends of the product.

[0040] The use principle of the utility model is now described as follows:

[0041] Insert the product into the clearance groove 31, and the spring pieces 32 on both sides of the clearance groove 31 are squeezed, releasing the elastic force to clamp the product, so that the product is connected and fixed with the detection fixture 3, and a thrust is applied to the detection fixture 3 to make it move toward the detection base 5. When the detection fixture 3 abuts the limit switch, the conductive lead end of the product is inserted into the conductive socket 51. The PLC controller 78 receives the signal of the limit switch and sends a command to the solenoid valve of the cylinder 61 to make it actuate, and the movable plate 62 moves downward, and the conductive clamp 63 clamps the conductive lead end of the product. At this time, the resistance tester 71 and the insulation resistance tester 7271 measure whether the resistance value and insulation value of the product are within the standard value range;

[0042] When any of the resistance value or insulation value exceeds the standard range, the alarm 77 sounds and the display screen 73 displays NG to warn the staff. Only when the product detected as NG is placed into the storage box 8 through the storage through hole 81 and the photoelectric sensor 82 detects that a defective product has entered, the alarm 77 will stop sounding.

[0043] When the resistance value and insulation value of the product are both within the standard range, the display screen 73 displays OK, the staff releases the thrust applied to the detection fixture 3, the tension spring 2 releases the elastic force, and the detection fixture 3 is quickly pulled back. As the distance between the detection fixture 3 and the limit block 12 gradually shortens, the spring 36 absorbs energy, reduces the movement speed of the detection fixture 3, and prevents the detection fixture 3 from colliding with the limit block 12, until the detection fixture 3 stops moving after abutting against the limit block 12, and the staff pulls out the product to proceed to the next operation.

[0044] The above design scheme can enable the product to achieve the advantages of improving detection efficiency, reducing manufacturing costs, and preventing the outflow of defective products.

[0045] The above content is a further detailed description of the utility model in combination with specific implementation methods.
