Provided is a servo amplifier system performing a multi-axis control for multiple axes, in which the multiple axes includes a first axis group which an axis to be locked, at the time of power supply abnormality in the multi-axis control, belongs to, and a second axis group which an axis to be subjected to servo-off belongs to, the servo-off being made before the axis belonging to the first axis group is locked at the time of the power supply abnormality.

The disclosure discloses an array substrate, a display panel, and a display device. A first power signal line is configured to be formed by electrically connecting a first signal line located in a first source-drain metal layer and a second signal line located in a second source-drain metal layer through a via hole, which is equivalent to that the first power signal line is composed of the first signal line and the second signal line connected in parallel, and the equivalent resistance of the parallel-connected first signal line and second signal line included in the first power signal line is smaller than the resistance of any of the signal lines. Thus, the resistance of the first power signal line may be effectively reduced, so that an IR drop of a display panel with an array substrate may be reduced, and the display uniformity of the display panel is improved.

A power supply control device for controlling a consumption current supplied from a power supply device to a tape feeder loaded on a component supply device, the component supply device being exchangeably loaded with multiple of the tape feeders, the power supply control device including: a consumption current acquiring section configured to acquire the consumption current corresponding to a state of the multiple tape feeders; a total consumption current calculating section configured to calculate a total consumption current that is a total of each of the consumption currents of the multiple tape feeders; and an operation controlling section configured to control the specified operation of the multiple tape feeders within a range in which the total consumption current does not exceed an output current capacity of the power supply device.

A soldering and de-soldering station and systems including enhanced features for the soldering heating tools and load detection functionality.

In a component-mounted-board production line in which an automatic exchanging device moves along a row of multiple component mounters, each component mounter is provided with a power supplying section that supplies power wirelessly. The automatic exchanging device is provided with a power receiving section that receives electric power supplied wirelessly from the power supplying section of the component mounter that the automatic exchanging device is facing, a monitoring section that monitors whether a person or object has entered a monitoring area around the automatic exchanging device, and a safety circuit section that turns off the power supply to a motor that is the driving source of the automatic exchanging device but continues supplying power to the monitoring section and the like when the monitoring section detects that a person or object has entered the monitoring area.

A spindle bank for a pick-and-place machine comprises a base including a plurality of mount locations, each of the plurality of mount locations configured to receive a mountable spindle module including at least one pick-and-place spindle and nozzle, a bearing system attachable to a movement axis of a pick-and-place machine such that the spindle bank is movable along the movement axis, and a power delivery system configured to deliver electrical power to each of the plurality of mount locations, wherein each of the plurality of mount locations is configured to deliver the electrical power to each of the mountable spindle modules when mounted.

A spindle for a pick-and-place machine includes a shaft including a length extending between a first end and a second end, the shaft including an outer body and a hollow interior, a nozzle tip disposed at the first end of the shaft, the nozzle tip configured to contact an electronic component for manipulation of the electronic component, and a theta gear disposed on the shaft, the theta gear configured to engage with a motor of a pick-and-place head. The spindle is configured to be removably attachable from the pick-and-place head. A dispensing head spindle module, spindle bank and assembly machine incorporating the spindle are disclosed.

A pick-and-place spindle module comprises: a modular body structure including a first receiving location configured to receive a spindle; a first z-axis motor configured to move a spindle received in the first receiving location in a z-axis; a first theta motor configured to rotate a spindle received in the receiving location; a first motion control chip each attached to the body structure, the first motion control chip configured to control the first z-axis motor and the first theta motor; and a mechanical attachment mechanism, the mechanical attachment mechanism configured to facilitate attachment of the modular body structure to a spindle bank.

A pick-and-place spindle module comprises a modular body structure including a first receiving location configured to receive a spindle, a first z-axis motor configured to move a spindle received in the first receiving location in a z-axis, a first theta motor configured to rotate a spindle received in the receiving location, an air distribution system including an air distribution port, the air distribution system configured to deliver received air from the air distribution port to a spindle received in the first receiving location, an electrical distribution system including an electrical distribution port, and a mechanical attachment mechanism, the mechanical attachment mechanism configured to facilitate attachment of the modular body structure to a spindle bank such that the air distribution port is connected to receive air from the spindle bank and the electrical distribution port is configured to receive electricity from the spindle bank.

A power supply control device that controls consumption currents that are supplied from power supply devices in a component supply device in which multiple tape feeders are replaceably installed, the device including: a total consumption current measuring section that obtains, based on measurement, a total consumption current by adding actual consumption currents which are supplied to a plurality of tape feeders; and an overcurrent protection section that causes a specific tape feeder, which is in an operation state, to transition to a stop state or a standby state, in a case of an overcurrent state where the total consumption current exceeds an output current capacity of the power supply device. Accordingly, even though the overcurrent state occurs during setup changing work in which the multiple tape feeders can operate, the overcurrent state is rapidly canceled, and thus a protecting function is improved.
