When the IO testing device needs to perform IO testing on a product to be tested, the product 20 to be tested (in this embodiment, a notebook computer) needs to be placed on the conveying mechanism, so that the carrier 10 carrying the product 20 to be tested is conveyed to the testing station of the testing platform. The method comprises the following specific steps:

s101, controlling a first conveying mechanism 2 to convey a carrier 10 carrying a product 20 to be detected to a first set position along a first direction, wherein the first direction is parallel to the upper surface of a detection platform 11;

s102, controlling a jacking conveying mechanism 4 positioned below a first conveying mechanism 2 to jack up a carrier 10 positioned at a first set position, and starting conveying the carrier 10 along a second direction until the carrier 10 is conveyed to a second conveying mechanism 3 of a rack 1, wherein the second direction is parallel to the upper surface of a detection platform 11 and is vertical to the first direction;

and S103, controlling the second conveying mechanism 3 to continuously convey the carrier 10 along the second direction until the carrier 10 is conveyed to the detection station of the detection platform 11, wherein the first conveying mechanism 2 is arranged right in front of the rack 1, and the second conveying mechanism is arranged on the detection platform 11.

Referring to fig. 2, in the present embodiment, the first direction is a left-right direction of the frame 1, the second direction is a front-rear direction of the frame 1, and the third direction is an up-down direction of the frame 1. Meanwhile, the first conveying mechanism 2 is a mechanism formed by a servo motor and a conveying belt, and the servo motor can drive the conveying belt to move back and forth along a first direction, so that the carrier 10 is driven to reach a set position; the second conveying mechanism 3 is also a servo motor and conveyor belt mechanism, and is different from the servo motor and conveyor belt mechanism in that the first conveying mechanism 2 conveys in a single direction, and the second conveying mechanism 3 conveys in a two-way manner so as to drive the carrier 10 to enter or leave the detection station; jacking transport mechanism 4 includes jacking cylinder, servo motor and conveyer belt, and wherein, the structure of servo motor and conveyer belt is similar with second transport mechanism 3, all is two-way conveying, and the difference lies in, the below of servo motor and conveyer belt still is equipped with a jacking cylinder, and this jacking cylinder sets up along the third direction to utilize this jacking cylinder can drive the distance that servo motor and conveyer belt rise or descend to set for, with corresponding with second transport mechanism 3. It can be understood that the specific structure of the first conveying mechanism 2, the second conveying mechanism 3, and the jacking conveying mechanism 4 in this embodiment is only one embodiment, and in other embodiments, other structures with conveying functions may be adopted instead.

And S20, controlling the clamping and positioning mechanism 5 to clamp and fix the products 20 to be detected on the carrier 10 so as to limit the relative positions of the products 20 to be detected.

During specific use, at first, it gets portion 63 and removes to the top of IO plug 7 to drive through triaxial mobile module 61, then, triaxial mobile module 61 drives to press from both sides portion 63 and descend, and spacing groove 6321 and the spacing projection 71 of IO plug 7 up to clamping jaw 632 are corresponding, and then, the cylinder 631 that opens and shuts drives clamping jaw 632 and folds to with spacing groove 6321 and spacing projection 71 looks block, and utilize this clamping jaw 632 to press from both sides tight IO plug 7, in order to avoid IO plug 7 to produce and rock, guarantee the reliability of inserting and closing. After the IO plug 7 is inserted into the IO socket, the opening and closing cylinder 631 drives the clamping jaw 632 to open, so that the clamping jaw 632 is separated from the IO plug 7, and at this time, the three-axis moving module 61 drives the clamping part 63 to ascend by a certain height and stop above the IO plug 7. After the IO detection is completed, the three-axis moving module 61 drives the clamping part 63 to descend again for clamping the IO plug 7 and returning to the original position, and the specific clamping process is the same as that described above and is not described herein again.
