Picking and placing mechanism and picking and placing device

Abstract

This invention relates to a pick-and-place mechanism and a pick-and-place device; the pick-and-place mechanism is suitable for picking up and placing a workpiece, and includes: a mounting frame with a first frame located above and a second frame located below; a drive module with a first driver located on the first frame and a second driver located on the second frame; a linkage module located on the mounting frame and having a splined screw; a retainer located at one end of the splined screw and capable of holding the workpiece; a transmission module located between the drive module and the linkage module and capable of transmitting power from the drive module to the linkage module; a first drive shaft of the first driver and a second drive shaft of the second driver are arranged facing each other; thereby, compared with the prior art, a shorter splined screw can be used to reduce manufacturing costs and facilitate the miniaturization of the pick-and-place mechanism.

Claims

1. A pick-and-place mechanism, suitable for picking up and placing a workpiece, comprising: a mounting frame having a first frame located above and a second frame located below; a drive module having a first driver located on the first frame and a second driver located on the second frame; a linkage module located on the mounting frame and having a splined screw; a retainer located at one end of the splined screw and capable of holding the workpiece; and a transmission module located between the drive module and the linkage module and capable of transmitting power from the drive module to the linkage module; characterized in that: a first drive shaft of the first driver and a second drive shaft of the second driver are arranged facing each other.

2. The picking and placing mechanism as described in claim 1, wherein, The first drive shaft of the first driver and the second drive shaft of the second driver are on the same central axis.

3. The picking and placing mechanism as described in claim 1, wherein, The mounting bracket has a transmission section between the first frame and the second frame, and the first drive shaft and the second drive shaft are located within the transmission section.

4. The picking and placing mechanism as described in claim 3, wherein, The first driver is provided with a first driving member that can drive the first drive shaft to rotate, and the second driver is provided with a second driving member that can drive the second drive shaft to rotate; the first driving member passes downward through the first frame from above, and the second driving member passes upward through the second frame from below.

5. The picking and placing mechanism as described in claim 1, wherein, The linkage module includes a first linkage component on the first frame and a second linkage component on the second frame, with the spline screw passing through the first linkage component and the second linkage component.

6. The picking and placing mechanism as described in claim 5, wherein, The first linkage assembly includes a first bearing assembly disposed on the first frame and a first kit pivotally disposed on the first bearing assembly; The second linkage assembly includes a second bearing assembly disposed on the second frame and a second kit pivotally disposed on the second bearing assembly.

7. The pick-and-place mechanism as described in claim 6, wherein, The splined screw has a threaded groove and two straight grooves. The threaded groove is located in the upper half of the splined screw, and the straight grooves pass through the threaded groove from the upper half of the splined screw to the lower half of the splined screw. The threaded groove corresponds to the first assembly, and the straight grooves correspond to the second assembly.

8. The picking and placing mechanism as described in claim 6, wherein, The transmission module has a first transmission component located at the top and a second transmission component located at the bottom. The first transmission component has a first drive pulley, a first transmission belt, and a first connecting pulley. The first drive pulley is connected to the first drive shaft, the first connecting pulley is connected to the first kit, and the first transmission belt is connected between the first drive pulley and the first connecting pulley.

9. The picking and placing mechanism as described in claim 8, wherein, The mounting bracket has a transmission section between the first frame and the second frame, and the first transmission component and the second transmission component are located within the transmission section.

10. The picking and placing mechanism as described in claim 1, wherein, The spline screw has a hollow interior with an air passage, and the retainer has a suction port; an air nozzle is connected to the other end of the spline screw opposite the retainer via a connector, and the suction port is connected to the air nozzle via the air passage.

11. A pick-and-place device using a pick-and-place mechanism as described in any one of claims 1 to 10, the pick-and-place mechanism being disposed on a multi-axis drive mechanism and being driven by the multi-axis drive mechanism to move in multiple axes.
