Device sorting apparatus
A device sorting apparatus 100 is disclosed herein. In a described embodiment, the device sorting apparatus 100 comprises a plurality of bin connectors 120 for coupling to respective bins for storing sorted devices and a rotary distribution module 102 for receiving a device 200 to be sorted and for discharging the device 200 selectively into one of the bin connectors 120 to enable the device 200 to be unloaded to the respective bin. The device sorting apparatus 100 further comprises a sensor 110 coupled to the rotary distribution module 102 for detecting the discharge of the device 200 , and which is rotatable together with the rotary distribution module 102 ; and a rotary transformer 400 for powering the sensor 110.
1. A device sorting apparatus, comprising
a plurality of bin connectors for coupling to respective bins for storing sorted devices;
a rotary distribution module for receiving devices to be sorted and for discharging the devices selectively into corresponding bin connectors to enable the devices to be unloaded to the respective bins;
a sensor coupled to the rotary distribution module for detecting the discharge of each device, and which is rotatable together with the rotary distribution module;
a rotary transformer having a primary transformer portion including a primary winding and a secondary transformer portion including a secondary winding, the secondary transformer portion and the primary transformer portion being separated by a gap and are rotatable relative to each other; the primary and secondary windings being configured to transfer power wirelessly from the primary transformer portion to the secondary transformer portion for powering the sensor.
2. A device sorting apparatus according to claim 1 , wherein the secondary transformer portion includes a rotor core configured to rotate together with the rotation of the sensor.
3. A device sorting apparatus according to claim 2 , wherein the rotary distribution module is configured to rotate about a same rotary axis as the rotor core.
4. A device sorting apparatus according to claim 1 , wherein the gap has a width of 2 mm.
5. A device sorting apparatus according to claim 1 , wherein the gap has a width of less than 2 mm.
6. A device sorting apparatus according to claim 1 , further comprising an encoder for determining an angular movement of the rotary distribution module, the encoder having an encoder shaft for coupling to the secondary transformer portion.
7. A device sorting apparatus according to claim 6 , further comprising a secondary clamping device coupled to the encoder shaft, the secondary clamping device being for clamping the secondary transformer portion to the encoder shaft.
8. A device sorting apparatus according to claim 1 , further comprising a primary device coupled to an end piece which is fixedly mounted to a housing of the device sorting apparatus, the primary device being for securing the primary transformer portion to the end piece.
9. A device sorting apparatus according to claim 1 , further comprising a sensor interface for transmitting a signal from the sensor to the primary transformer portion via the secondary transformer portion and the gap, the signal being operative to determine when each device is discharged out of the distribution module.
10. A device sorting apparatus according to claim 1 , further comprising a sensor amplifier for amplifying signals to or from the sensor.
11. A LED sorting apparatus comprising the device sorting apparatus according to claim 1 .
