A work system includes multiple work devices aligned along a board conveyance line, a replenishing device having a sensor for detecting presence or absence of an interfering object and configured to move in parallel with the board conveyance line while detecting the presence or absence of the interfering object by the sensor to replenish necessary members to the multiple work devices, and a draw-out device configured to draw out at least one of the multiple work devices in a direction orthogonal to a direction along the board conveyance line. When a draw-out request for the work device is made, the replenishing device performs an automatic draw-out process of moving to a position in which a draw-out position of the work device to be pulled forward is included within a detection range of the sensor, so as to determine whether the interfering object is detected by the sensor.

An apparatus and method for dissembling electronic devices are described. The apparatus includes a housing with an aperture providing access to an interior thereof, and an adjustable support assembly positioned therein. The support assembly includes a first side plate and a second side plate with spacing in between, and a base plate for supporting an electronic device. A user interface is provided for receiving a user input, and in response to the user input, a motor is configured to drive a ram member downwards to contact and apply force to the electronic device held in the support assembly. A sensor may be included to measure the motor load current and output the measured load to an indicator to be viewed by a user for determining when a shell of the electronic device has been cracked.

A control method and apparatus for a smart power component, a storage medium and a processor are provided. The method includes that: first fitting information and second fitting information, which is detected by the smart power component, between a smart power component and an external heat sink is acquired; it is determined whether the first fitting information satisfies a preset condition, and it is determined whether the second fitting information satisfies a preset condition; when the first fitting information does not satisfy the preset condition, first prompt information is output; and when the second fitting information does not satisfy the preset condition, second prompt information is output. Thus, the technical problem that a poor fit between a smart power component and an external heat sink is not detected is solved.

A tape feeder includes a magnet that rotates as one with a sprocket driven by a motor, two magnetic field detecting elements that detect signals in accordance with a magnetic field from the magnet and that are arranged at positions opposite the rotation region of the magnet, and a rotation angle detecting circuit that detects the rotation angle of the magnet and the rotation angle of the sprocket by processing output signals of the magnetic field detecting elements. A control section of the tape feeder reads the detection information of the rotation angle detecting circuit from immediately after the motor is started, recognizes the rotation angle of the sprocket, detects the position of tooth of the sprocket of the tooth engaged with a feeding hole of component supply tape based on the recognition results of the rotation angle of the sprocket for each pitch feeding operation of the sprocket, and corrects the pitch feeding amount of the motor by a pitch error correcting amount set for the tooth.

A tape feeder including: an angle sensor configured to detect a final angle of the sprocket at a point in time at which interruption of power supply to the tape feeder is detected, and a current angle of the sprocket at a point in time at which resumption of power supply to the tape feeder is detected; and a control device configured to, when resumption of power supply to the tape feeder is detected, set a target angle of the sprocket based on the final angle, and perform control to rotate the sprocket from the current angle to the target angle so as to convey the carrier tape to a predetermined position.

A component mounting machine including a component supply device to supply a component to a supply position; a component transfer device to pick up the component from the supply position and mount the component on a board; a component detecting section to detect whether the component is present at the supply position before or while the component is being picked up by the component mounting tool; a holding detecting section to detect whether the component mounting tool is holding the component following pickup; and a retry performing section to determine whether to perform a retry operation of attempting to pick up the component again using the component mounting tool based on a detection result of the component detecting section and a detection result of the holding detecting section, and to perform the retry operation in accordance with a result of the determining of whether to perform the retry operation.

A method of assessing a cleanliness of an assembly in a panel during a manufacturing process is provided, wherein an electrical signal of at least one of a predetermined voltage, current or frequency is applied across a first subset and a second subset of nonconnected electrical contacts in a test coupon associated with the assembly, such that the first subset and the second subset have different pitches. In one configuration, the test coupon is tested at higher voltages, currents or frequencies to a point of failure or above a predetermined threshold.

A load measuring device is provided with load sensor, data logger, and measurement start switch on body. When switch section is pressed down by a suction nozzle, load sensor outputs detection voltage to data logger in accordance with the size of the pressing load. Data logger records detection voltage for a specified time only from the time it starts receiving high level start recording signal from measurement start switch. By this, data logger does not record detection voltage until high level start recording signal is received from measurement start switch, thus does not incorrectly record vibrations and the like during conveyance as the load.
