Magnetic pickup and release module, magnetic pickup and release mechanism and magnetic pickup and release device

Abstract

This invention provides a magnetic pickup and release module, a magnetic pickup and release mechanism, and a magnetic pickup and release device. The magnetic pickup and release module includes a fixed base, a movable base, an elastic member disposed between the fixed base and the movable base, and a magnetic unit. The fixed base has an inner channel extending along a first direction and suitable for inserting a hollow shaft. The movable base has an insertion channel extending along the first direction and suitable for inserting the fixed base and a drive shaft, a body surrounding the insertion channel, and a contact wall connected to the body and located at the end of the insertion channel opposite to the fixed base. The contact wall is suitable for contacting the workpiece. The magnetic unit is disposed within the insertion channel and enclosed by the movable base, thus the magnetic unit is not contaminated or damaged by the workpiece or the external environment.

Claims

1. A magnetic pickup and release module, suitable for use with a hollow shaft and a drive shaft inserted into the hollow shaft, and suitable for adsorbing a workpiece, the magnetic pickup and release module comprising: a fixed base having an inner channel extending along a first direction and suitable for inserting the hollow shaft; a movable base movable relative to the fixed base, having an insertion channel extending along the first direction and suitable for inserting the fixed base and the drive shaft, a body surrounding the insertion channel, and a contact wall connected to the body and located at one end of the insertion channel opposite to the fixed base, the contact wall being suitable for contacting the workpiece; an elastic element disposed between the fixed base and the movable base; and a magnetic unit having magnetism and disposed in the insertion channel, the magnetic unit being suitable for being driven by the drive shaft to move along the first direction.

2. The magnetic pickup and release module as described in claim 1, wherein, The magnetic unit has a housing suitable for mounting on a drive shaft, and a magnetic element disposed in the housing.

3. The magnetic pickup and release module as described in claim 2, wherein, The housing is provided with a housing wall located between the contact wall of the magnetic element and the movable seat, and the magnetic unit is also provided with a pad located between the housing wall and the magnetic element.

4. The magnetic pickup and dispensing module as described in claim 3, wherein, The magnetic element abuts between the drive shaft and the pad, and is limited by the drive shaft and the pad so that it cannot move relative to the housing in the first direction.

5. The magnetic pickup and release module as claimed in claim 1 further comprises a housing surrounding the fixed base and the movable base, and a guide member inserted into the housing and the movable base, the housing being provided with a guide groove for the guide member to move up and down.

6. The magnetic pickup and release module as described in claim 5, wherein, The housing is also provided with limiting walls located on two opposite sides of the guide groove, each of which abuts against the guide member.

7. The magnetic pickup and release module as described in claim 1, wherein, The insertion channel of the movable seat is provided with a closed chamber spaced apart from the inner channel of the seat, and a movable chamber connecting the inner channel of the seat and the closed chamber. The magnetic unit is adapted to be driven to move between the closed chamber and the movable chamber along the first direction.

8. The magnetic pickup and release module as described in claim 7 further comprises a housing surrounding the fixed base and the movable base, the housing having an internal space for accommodating the fixed base and the movable base, the internal space cooperating with the movable chamber for the movable base to move relative to the fixed base.

9. The magnetic pickup and release module as claimed in claim 1 further comprises a plurality of first fasteners that extend laterally and are inserted into the fixed base, each of the first fasteners being adapted to abut against the hollow shaft.

10. A magnetic pickup and release mechanism, comprising: a frame; a first drive unit disposed on the frame and provided with a first power source, and a hollow shaft as described in any one of claims 1 to 9, the hollow shaft being driven to rotate by the first power source; a second drive unit disposed on the frame and provided with a second power source, and a drive shaft as described in any one of claims 1 to 9, the drive shaft being driven to move up and down by the second power source; and a magnetic pickup and release module as described in any one of claims 1 to 9, wherein the inner channel of the fixed base allows the hollow shaft to be inserted for the magnetic pickup and release module to be assembled on the hollow shaft.

11. The magnetic pickup and dispensing mechanism as described in claim 10, wherein, The frame is provided with a first frame portion that supports the first drive unit. The first frame portion has a first frame hole that extends along the first direction and accommodates the fixing seat of the magnetic suction and release module, and a through hole that extends laterally and connects to the first frame hole.

12. A magnetic pickup and release device, comprising: a multi-directional moving mechanism and a magnetic pickup and release mechanism as described in claim 10 or 11, the multi-directional moving mechanism being capable of moving the magnetic pickup and release mechanism in multiple directions.
