As shown in fig. 2, a sliding rope 29 is fixedly connected to the wedge-shaped block 07, a fixed sleeve seat 31 is fixedly connected to the inner wall of the air cylinder 05, a wind shield 30 is connected to the inner side of the fixed sleeve seat 31 in a limiting sliding manner, the turntable 04, the exhaust pipe 06, the air suction table 17, the wedge-shaped block 07, two sets of sliding ropes 29 are arranged in a mirror image manner, the two sets of sliding ropes 29 extend into the air cylinder 05 and are respectively and fixedly connected to the two ends of the wind shield 30, the air suction device further comprises a pushing assembly which enables the wedge-shaped block 07 positioned at the two sides of the mirror image to move towards the direction close to the turntable 04, the air suction device further comprises two spaced scanners 16 which are arranged between the two air suction tables 17 and can perform scanning detection, the air cylinder 05 can be driven to rotate, and the air suction device can generate negative pressure in the air cylinder 05.

During implementation, a plurality of turntables 04, an exhaust pipe 06, an air suction table 17, a wedge block 07 and a sliding rope 29 can be arranged on the air cylinder 05 at equal intervals to improve the working efficiency, the air suction table 17 is made of transparent materials, interference on lines of components during scanning can be reduced, and the misjudgment probability is reduced. In operation, the negative pressure device will generate a negative pressure in the inflator 05, which will cause the suction table 17 to draw air through the exhaust hose 06, thereby enabling the suction table 17 to generate suction. The air cylinder 05 is driven to rotate at a constant speed by the driving rotation, and the rotation of the air cylinder 05 drives the turntable 04 to drive the air suction table 17 to rotate simultaneously.

And then, the next detection process of the air suction table 17 can not be influenced by blanking the detected components.

Be different from current technique, this technique adopts the platform 17 that induced drafts to catch components and parts, does not need solitary anchor clamps to realize holding with of components and parts to reduce the possibility that shelters from to components and parts, thereby guarantee the precision when detecting. Meanwhile, dust stuck on the components or sundries such as dust scraps during production can be sucked into the air suction table 17 through the suction force generated by the air suction table 17, so that the surfaces of the components are cleaner, and misjudgment caused by the dust is reduced. And electronic components itself is less and comparatively fragile, it not only reduces the rigid contact to components and parts to fix through the wind-suction, can also be convenient for fix components and parts fast when preventing to press from both sides bad damage with components and parts, simultaneously can realize through promoting the subassembly that contactless messenger electronic components from the platform 17 that induced drafts of top switches on the platform 17 that induced drafts of below, adsorb fixedly, thereby detect the whole of components and parts under the non-contact condition, the problem that just can detect the two sides after need carry out the turn-ups to components and parts among the traditional device has been solved, and is not only efficient, can fully detect, reduce the contact of testing process to components and parts, thereby reduce the clamp to the device and hinder and shelter from.

A first slide rod 21 is connected to the upper limit of the first fixing plate 24 in a sliding mode, a second triangular block 22 capable of pushing the second slide rod 23 to move upwards towards the slide way 12 when the first slide rod 21 moves towards the second slide rod 23 is arranged at one end, close to the second slide rod 23, of the first slide rod 21, and a first triangular block 20 is fixedly connected to one end, far away from the second triangular block 22, of the first slide rod 21. The outer wall of the sliding rod I21 is sleeved with a spring which can enable the sliding rod I21 to reset towards the direction far away from the sliding rod II 23, one side face, close to the slide way 12, of the rotary table 04 is fixedly connected with a push rod 19 which can push the triangular block I20 to move towards the direction close to the sliding rod II 23 when the rotary table 04 rotates, and along with the rotation of the rotary table 04, the central point of the material ejecting table 36 can coincide with the central point of the air suction table 17.

In practice, the width of the slide 12 is ensured to allow only one component to pass through at the same time, so that the width of the slide 12, the size of the material ejecting table 36 and the ascending distance of the second slide rod 23 can be set according to components with different sizes.

Because the platform 17 that induced drafts is adopted and is carried out the fixed suction that just induced drafts platform 17 and enough live with components and parts, when adopting induced drafts platform 17 and directly inhales the material to the raw materials, can lead to induced drafts platform 17 can once hold a plurality of components and parts, but when detecting, the principle that most device detected all is the photo of scanning when the photo contrast that adopts the template detects, consequently for single contrast, once a plurality of materials will lead to unable the contrast that detects, influence the effect that detects. The material is fed by lifting the material ejecting table 36, only one material is pushed to lift at each time, in the lifting process, the material ejecting table 36 blocks other components to prevent the other components from continuously sliding downwards, when the material ejecting table 36 moves downwards, one component rolls on the material ejecting table 36 and blocks other components to prevent the other components from continuously falling, and therefore only one material is fed at each time. And because the platform 17 that induced drafts is rotating along with carousel 04, carry out the upward movement through setting up the liftout platform 36 and carry out the pay-off and can reduce the time when components and parts are inhaled and induced draft on the platform 17 to thereby guarantee that components and parts can be more when being inhaled the intermediate position that is close to the platform 17 that induced drafts and guarantee the enough of suction, be difficult for dropping, contrast when being convenient for simultaneously scan.
