Further, a first support column is provided between the first support plate 21 and the second support plate 22; and a second support column is provided between the second support plate 22 and the third support plate 23. The layered support bracket 2 can ensure the installation stability of the components, reduce the obstruction and interference between each other, and thus improve the stability of use.

[0035] Specifically, in some embodiments, Figure 2As shown, the adsorption positioning component 4 includes a driving component 41 and an adsorption component 42; the driving component 41 is connected to the support bracket 2, and the movable end of the driving component 41 is connected to the adsorption component 42; the adsorption end of the adsorption component 42 is adsorbed and connected to the electronic mainboard.

Figure 3 and 4 As shown, the clamp 32 includes a clamping plate 321, an abutment plate 322 and an elastic limiter 323; one end of the abutment plate 322 is movably connected to the inside of the clamping plate 321; the other end of the abutment plate 322 is connected to one end of the elastic limiter 323, and the other end of the elastic limiter 323 is connected to the inside of the clamping plate 321; and a clamping cavity 324 is provided between the bottom end surface of the abutment plate 322 and the inner wall of the clamping plate 321. Among them, the elastic limiter 323 is a limit spring; the clamping plate 321 is a U-shaped plate; and the transverse support shaft 311 is a Z-shaped support shaft. In other words, when the electronic mainboard enters from the opening of the clamping cavity 324, the other end of the abutment plate 322 and the elastic limiter are pushed upward as the electronic mainboard goes deeper, and the electronic mainboard is limited and clamped under the action of the elastic relative force of the elastic limiter.

The conveying component 6 includes a conveying motor, a conveying gear and a conveying belt / chain. That is, the conveying component 6 stops conveying the electronic motherboard after conveying it to the placement station, and then conveys it after the clamping component 3 and the adsorption positioning component 4 clamp and detect it, so as to improve the smoothness and efficiency of the conveying.

[0041] Specifically, in some embodiments, the adsorption end of the adsorption positioning component is adsorbed and connected to the conveying component 6 or the electronic main board. That is, when the conveying component 6 stops, the conveying belt / chain of the conveying component 6 is adsorbed and fixed by the adsorption end of the adsorption positioning component to avoid shaking and the like, thereby improving the stability of operation; at the same time, the adsorption end of the adsorption positioning component can also be used to adsorb the electronic main board to avoid shaking and the like of the electronic main board.
