Support pin for supporting a substrate in a placement area of a placement machine
The invention relates to a support pin ( 10 ) for supporting a substrate ( 80 ) in a placement area of a placement machine ( 100 ) and a placement machine ( 100 ) with at least one placement head ( 101 ), a magazine ( 104 ) with a plurality of such support pins ( 10 ) and a placement board ( 103 ).
1 . A support pin for supporting a substrate in a placement area of a placement machine, comprising an upper segment designed to support the substrate and to releasably receive the support pin via a placement head of the placement machine; a lower segment having at least one permanent magnet for magnetically coupling with a placement board in the placement area; and a central segment extending between the upper segment and the lower segment, wherein the at least one permanent magnet can be rotated with respect to a base of the lower segment by means of a rotating spindle of the support pin, wherein the base has at least one coupling area and at least one non-coupling area, such that the at least one permanent magnet is movable by means of rotation relative to the base between a coupling position, in which the at least one permanent magnet faces the at least one coupling area, and a non-coupling position, in which the at least one permanent magnet faces the at least one non-coupling area, and wherein the at least one permanent magnet is magnetically couplable to the placement board in the coupling position and is not magnetically couplable with the placement board in the non-coupling position when the support pin is provided on the placement board.
2 . The support pin according to claim 1 , wherein the at least one coupling area is formed by a magnetisable material and the at least one non-coupling area is formed by a non-magnetisable material.
3 . The support pin according to claim 1 , wherein the at least one non-coupling area is formed by a recess in the base.
4 . The support pin according to claim 1 , wherein the base has at least two or at least three coupling areas and at least two or at least three non-coupling areas.
5 . The support pin according to claim 4 , wherein the coupling areas are formed to have rotational symmetry about the rotating spindle and/or the non-coupling areas are formed to have rotational symmetry about the rotating spindle.
6 . The support pin according to claim 1 , further comprising a rotating device coupled to the rotating spindle and connected to a fluid channel of the support pin extending in the upper segment which is configured to rotate the rotating spindle relative to the base by generating a vacuum or supplying compressed air in the fluid channel.
7 . The support pin according to claim 1 , wherein the lower segment is designed as a housing enclosing the at least one permanent magnet.
8 . The support pin according to claim 7 , wherein the housing is designed as a stand.
9 . A placement machine comprising: at least one placement head; a magazine with a plurality of support pins according to claim 1 ; and a placement board, wherein the at least one placement head is movable between the magazine and the placement board, and wherein the at least one placement head is designed to remove the support pins from the magazine and configure the support pins on the placement board.
