[0038] The third driving mechanism 41 drives the sliding component 434 to slide in the interior of the sleeve 42, thereby driving the adsorbing component 431 and the positioning component 432 to slide; it should be noted that the outer diameter of the sliding component 434 is matched with the inner diameter of the sleeve 42, so as to avoid shaking of the sliding component 434 in the process of sliding, and to prevent the material from being shaken off or the posture of the material from being inaccurate, thereby affecting subsequent material falling.

[0053] To this end, the first driving mechanism 22 and the second driving mechanism 32 can be set to start to decelerate when the first sliding seat 21 and the second sliding seat 31 are about to reach a specified position, so as to slow down the speed of the first sliding seat 21 and the second sliding seat 31 until the first sliding seat 21 and the second sliding seat 31 stop sliding, which can reduce the swing amplitude of the material or avoid the swing of the material, ensure the posture of the material to be correct, and align the material with the assembly hole of the mold and accurately fall into the assembly hole.

The second direction and the third direction are parallel and perpendicular to the first direction.

2. The pick-and-place apparatus of claim 1, wherein, The suction accessory comprises a suction component and a positioning component, the suction component has a suction side for adsorbing the fastener, and one end of the positioning component extends from the middle of the suction side and forms the suction head together with the suction side.

3. The pick-and-place apparatus of claim 2, wherein, The suction accessory further comprises a sliding component, one end of the sliding component is connected to the power end of the third driving mechanism, and the suction component is arranged at the other end of the sliding component. The main body of the positioning component is arranged in the interior of the sliding component and passes through the interior of the suction component, and one end of the positioning component extends out of the suction side of the suction component.

4. The pick-and-place apparatus of claim 3, wherein The suction component comprises a magnetic suction element.

5. The pick-and-place apparatus of claim 3, wherein, The third driving mechanism comprises a corresponding number of linear driving members corresponding to the sleeve, and the linear driving members have power ends that can move back and forth along a straight line. The power ends of the linear driving members extend into the interior of the sleeve and are connected to the sliding component.

6. The pick-and-place apparatus of claim 5, wherein, The first displacement assembly further comprises a first driving mechanism arranged on the machine base, the power end of the first driving mechanism is connected to the first sliding base, and the first driving mechanism drives the first sliding base to slide along the first direction. The second displacement assembly further comprises a second driving mechanism arranged on the first sliding base, the power end of the second driving mechanism is connected to the second sliding base, and the second driving mechanism drives the second sliding base to slide along the second direction.

7. The pick-and-place apparatus of claim 6, wherein, The machine base is provided with a first sliding rail extending along the first direction, and the first sliding base is slidingly arranged on the first sliding rail. The first sliding base is provided with a second sliding rail extending along the second direction, and the second sliding base is slidingly arranged on the second sliding rail.

8. The pick-and-place apparatus of claim 7, wherein, The machine base is provided with a pair of first buffer members and a pair of second buffer members. The first buffer members are arranged at the start position and the end position of the sliding stroke of the first sliding base, respectively, for buffering and decelerating the first sliding base. The second buffering members are respectively arranged at the start position and the end position of the sliding stroke of the second sliding seat, and are used for buffering and decelerating the second sliding seat.

9. The pick-and-place apparatus of claim 8, wherein, The base is further provided with a pair of first limiting blocks and a pair of second limiting blocks. The first limiting blocks are respectively arranged at the start position and the end position of the sliding stroke of the first sliding seat, and are used for limiting the sliding of the first sliding seat. The second limiting blocks are respectively arranged at the start position and the end position of the sliding stroke of the second sliding seat, and are used for limiting the sliding of the second sliding seat.

10. The pick-and-place apparatus of claim 6, wherein, The base comprises a bottom plate, a side plate, a plurality of reinforcing plates and a vertical plate. The side plate is perpendicular to the upper side of the bottom plate, the reinforcing plates are connected to the bottom plate and the side plate, and the vertical plate is connected to the side plate perpendicularly.
