Portion-wise filling of a reservoir with bulk components
A magazine ( 200 ) is described for portion-wise receiving individualized bulk electronic components ( 298 ). The magazine ( 200 ) comprises (a) a receiving structure ( 110 ) which comprises multiple closable receiving cavities ( 112, 112 a ), which are arranged along a longitudinal axis ( 100 a ) of the receiving structure ( 110 ); (b) a cover structure ( 120 ) which is arranged at an upper side of the receiving structure ( 110 ), displaceable along the longitudinal axis ( 100 a ), so that in a closed position of the cover structure ( 120 ) all receiving cavities ( 112, 112 a ) are covered and in one opening position of multiple opening positions at least one receiving cavity ( 112 ) is free; and (c) a closure foil ( 225 ) which encompasses the cover structure ( 120 ) along the longitudinal axis ( 100 a ) in the form of a closed tape, wherein at least a part of the closure foil ( 225 ) is releasably connected to the receiving structure ( 110 ). Further, a device ( 430 ) is described for portion-wise transferring components ( 298 ) from one such magazine ( 200 ) into a reservoir ( 490 ) for a component supply device. Further, a method is described for portion-wise transferring components from one such magazine ( 200 ) into the one such reservoir ( 490 ).
1. A device for portion-wise transferring individualized bulk electronic components
(i) from a magazine which has multiple closable receiving cavities along a longitudinal axis, in each of which a plurality of electronic components are stored,
(ii) into a reservoir for a component supply device for providing individualized components for the purpose of automatic assembly of component carriers in a placement machine by means of vibration, the device comprising:
a frame;
a holding device mounted on the frame for holding the reservoir stationary, wherein the reservoir is orientated in such a manner that a filling opening of the reservoir is located on the upper side with respect to gravity; and
a magazine receiving device mounted on the frame for receiving the magazine in such orientation that components which are located in a receiving cavity fall down into the filling opening under influence of gravity upon opening of the receiving cavity;
a turning device which connects the magazine receiving device with the frame and which is formed such that the magazine receiving device is movable between a receiving position and a withdrawal position, wherein
(i) in the receiving position, the magazine can be inserted into the magazine receiving device in an orientation in which openings of the receiving cavities are on top, and
(ii) in the withdrawal position, the received magazine has a turned orientation.
2. The device according to claim 1 , wherein in the withdrawal position, the received magazine has a turned orientation around 180°.
3. The device according to claim 1 , further comprising:
a holding-down device which is arranged on the turning device and movable between an opening position and a closing position and which is designed in the opening position, to allow insertion of the magazine into the magazine receiving device and in the closing position, to hold the magazine in the magazine receiving device.
4. The device according to claim 1 , further comprising: a displacing device which is adapted to displace at least one receiving structure of the magazine along the longitudinal axis in order to sequentially open the receiving cavities.
5. The device according to claim 4 , wherein the displacing device comprises a driver element that is displaceable with respect to the frame parallel to the longitudinal axis, which driver element is in engagement with a carrier element of a turning device that is displaceable along the longitudinal axis wherein the carrier element is configured to hold the receiving structure of the magazine.
6. The device according to claim 5 , wherein the driver element and an engagement element of the carrier element are in engagement independently from the position of the turning device.
7. The device according to claim 5 , further comprising: a blocking mechanism that is formed such that a displacing of the carrier element by means of the displacing device is exclusively possible when the magazine receiving device is in the withdrawal position.
8. The device according to claim 1 , further comprising: an operational condition determination system which is mounted on the frame and which is designed to recognize at least one of the following conditions:
(a) a marking is arranged on the magazine, indicating that the components in the magazine are of the same type as components that are to be transferred into the reservoir;
(b) the magazine receiving device is in the receiving position;
(c) the magazine receiving device is in the withdrawal position;
(d) the holding device is in an opening position;
(e) the holding device is in a closing position.
9. The device according to claim 1 , further comprising: a reservoir determination system which is arranged to recognize at least one of the following conditions:
(a) a reservoir is held by the holding device;
(b) the reservoir held by the holding device is in a predetermined position; and
(c) the reservoir held by the holding device comprises a marking indicative that the reservoir is a predetermined reservoir.
10. The device according to claim 9 , wherein the reservoir determination system is mounted on the frame.
11. The device according to claim 1 , further comprising: an actuator which is mounted on the frame and which is positioned and adapted such that a shutter of a reservoir held by the holding device can be displaced between a first position and a second position, wherein in the first position the reservoir is opened, so that the reservoir can be filled with components, and in the second position the reservoir is closed, so that no components can enter the reservoir or can exit it.
12. The device according to claim 11 , wherein the holding device cooperates with the actuator and is configured such that inserting the reservoir into the holding device and withdrawing the reservoir from the holding device is possible only when the shutter of the reservoir is in the second position.
