摘要:
Utility of a circuit-substrate working machine including a substrate conveyor device and a shuttle conveyor designed to shift a circuit substrate in a direction intersecting a conveying direction is improved. Based on transmission of a deliverable-state advance notification signal for one of conveyor lanes of an upstream printer, a movable conveyor lane of an intermediate shuttle conveyor is moved to a position continuous to the one conveyor lane. The circuit substrate is delivered to the movable conveyor lane in a state in which the movable conveyor lane is located at a circuit-substrate receiving position, a receivable-state advance notification signal is produced for a receiving lane for receiving the circuit substrate supplied from one of conveyor lanes of a downstream printer which has transmitted a deliverable-state advance notification signal, and a receivable-state signal and a deliverable-state signal are obtained. The circuit substrate is then delivered to the receiving lane.

An improved screen printing machine is provided. The main body portion and the support table portion of the printer main body are constructed independently of each other, and the main body portion is supported by the support table portion so as to be movable forward. A feed screw is axially immovably and rotatably held by the main body portion so as to be parallel to the front and rear direction, and the feed screw is engaged with the nut provided on the support table portion. An operator rotates the handle attached to the feed screw to move the main body portion forward with respect to the support table portion so that the main body portion is drawn from the support table portion.

A method of controlling an operation of an operating member from a first position to a second position, wherein an operating speed of the operating member is initially increased from zero while an acceleration value of the operating member is first increased from zero and then decreased to zero, and the operating speed is subsequently decreased while the acceleration value is first decreased from zero and then increased to zero, and wherein a derivative of the acceleration value of the operating member is controlled such that the derivative during an acceleration increasing time and the derivative during an acceleration decreasing time are asymmetric with respect to each other. Also disclosed in an operating device including the operating member and a control device having an asymmetric control portion configured to practice the control method.

When a printed circuit board is inspected and determined to have an insufficient amount of printing of a print pattern, the printed board is returned to a screen-printing apparatus so that a new print pattern is formed so as to overlap a previous print pattern. In the re-printing, a raising speed of the printed board at a final stage of the board raising operation is rendered lower than in the previous screen printing so that the printed board is brought into contact with the underside of the screen mask more slowly.

A squeegee device includes a squeegee that has a sliding contact portion in sliding contact with a screen mask, and that prints a solder on a circuit board through the screen mask, wherein an attack angle of the squeegee is adjustable. In the squeegee device, when adjusting the attack angle during a tooling change in which the type of circuit board is changed, positions of the sliding contact portion before and after adjustment substantially match.

An existing electronic part mounting device can have the function of correcting the parallax of a camera pickup image only by addition or modification of software without using a telecentric lens. For this, storage means stores in advance parallax data representing the relationship between the height of an electronic part to be picked up by a camera and a part size per pixel for each pixel of the pickup image or image magnification. When picking up the electronic part adsorbed by an adsorption nozzle (11) by the camera, the part height data on the height of the electronic part is acquired, so that according to the part height data and the aforementioned parallax data, a part size per pixel or image magnification is corrected for each pixel of the pickup image of the electronic part, thereby correcting the parallax of the pickup image of the electronic part.

Assisting-work management apparatus and an assisting-work management program for performing the assisting work in a substrate work machine system efficiently by a plurality of workers. A worker determining section (140) determines a worker to perform an objective work obtained according to assisting work occurrence information acquired by an assisting work occurrence information acquiring section (110) and a work informing section (180) informs the determined worker of the objective work. The workers determining section (140) can determine the worker of the objective work appropriately based on set worker information, current worker information, the worker intension, and the like.
