A board work system including: a conveying and holding device including a pair of rails configured to support a board, and a changing mechanism configured to change a distance between the pair of rails, the conveying and holding device being configured to convey the board supported by the rails and hold the board at a work position; a work device configured to perform work with respect to the board held by the conveying and holding device from an underside of the board; a moving device configured to move the work device; and a control device, the control device including an acquiring section configured to acquire a rail spacing distance that is the distance between the pair of rails, and an operation control section configured to control operation of the moving device based on the rail spacing distance acquired by the acquiring section.

An electronic component mounter is provided which easily detects penetrating portions. An electronic component mounter comprises a holding section configured to hold a board having a penetrating portion penetrating the board in a front-rear direction and into which a lead of an electronic component is inserted; a light section disposed on one face from among the front face and the rear face of the board when the board is held by the holding section and configured to irradiate a light beam, which is direct light or reflected light, on to the board; and a light receiving section disposed on the other face from among the front face and the rear face of the board when the board is held by the holding section and configured to receive the light beam via the penetrating portion.

A lead component mounting machine is provided in which lead wires are pinched and held from both sides by a pair of pawl portions, and the lead wires are inserted into through-holes of a board. The holding by the pawl portions is loosened, and a component main body is pushed in by a pushing-in device until the component main body comes into contact with the pawl portions. Subsequently, the strength of the holding by the pawl portions is increased, and the cutting and clinching of the lead wires is performed. Sliding movement of the lead wires is in a state of being suppressed by the pawl portions.

In a component insertion machine for inserting a component P with a lead into a board, when the lead is cut by lead cutting device 20 having fixed blade 60 and movable blade 62 prior to insertion, the component is moved (X) to a position where the lead approaches or contacts the fixed blade, at which position the movable blade is operated to cut the lead.

A clinch mechanism for assembling a printed circuit board with electronic components includes a drive shaft configured to move along a vertical axis, a stationary anvil configured to remain stationary during movement of the drive shaft, a cutter having a cutting tip, and a toggle configured to rotate about a toggle rotation axis that includes an involute gear shaped tooth configured to roll across an involute trapezoidal slot of the cutter in order to impart movement on the cutter relative to the stationary anvil. Movement of the drive shaft along the linear axis is configured to move the cutter relative to the stationary anvil, and to move the cutting tip across the stationary anvil to cut an electronic lead located between the cutting tip and the stationary anvil, and to rotate the toggle about the axis.

In a cut and clinch device, movable section 122 is slidable with respect to main body section 120. Also, a first insertion hole is formed in main body section 210, and a second insertion hole 136 is formed in curved section 133 of movable section 122 in a state overlapping the first insertion hole. A lead is cut by the movable section being slid with the lead inserted into the first insertion hole and the second insertion hole. In such a cut and clinch device, a pair of recognition marks 210 are provided on a bent section opposite each other centered around the second insertion hole. Thus, the recognition marks are imaged, and based on the image data, it is possible to appropriately recognize the opening position of the second insertion hole, to appropriately insert the lead into the second insertion hole, and to appropriately cut the lead.

The inspection support device is provided with a camera provided on a moving body so as to be capable of imaging a circuit board, and an imaging control section configured to control imaging processing of the camera and acquire image data of an inspection component, which is a component that is a target for inspection among electronic components mounted by the component mounter, when the inspection component is mounted on the circuit board. The imaging control section optimizes the performance sequence of multiple of the mounting operations and multiple of the imaging operations based on a moving distance of the moving body during the performance sequence or based on a time required for the mounting operation and the imaging operation during the performance sequence.

A component mounter includes a substrate conveying-and-holding device 22 configured to convey a board, work heads 60, 62 configured to hold a component, a work head moving device 64 configured to shift the work heads above the board, multiple work units 34, 36, 37 configured to perform work on the board from below, and a unit moving device 35 configured to shift the work units below the board, and each of the multiple work units is mounted on a mounting section of the unit moving device in an exchangeable fashion. With the substrate work machine configured as described above, the board can be worked on from above and below, hence making it possible to deal with various types of work. In addition, by exchanging the work units mounted in the mounting section, further types of work can be dealt with.

A cut-and-clinch apparatus that cuts and bends protruding parts of two lead wires of a lead component to be respectively inserted through two of a plurality of through-holes formed in a circuit board, the cut-and-clinch apparatus includes a pair of movable elements that are used in a case where the respective protruding parts of the two lead wires are cut and bent and that are made to approach each other and separate from each other, and a movable element position control section that controls the positions of the pair of movable elements, on the basis of image data obtained by the pair of movable elements being imaged.

Movable section of a cut and clinch unit includes exchange section in which is formed second insertion hole for cutting and bending a lead, and main body section to which exchange section is removably attached. An opening position of the second insertion hole is calculated as an attachment position of the exchange section on the main body section based on image data. It is determined whether a difference between the calculated opening position and a standard position of the second insertion hole that is set in advance exceeds a threshold value. If the difference between the calculated opening position and the standard position exceeds the threshold value, calibration is performed based on the assumption that the exchange section has been exchanged.
