Method and apparatus for mounting electronic components in which components are efficiently fed and transferred for enhancing productivity is provided. Tray draw-out device (6) is disposed at a component feeding unit (4) for pulling out a tray (3) accommodating electronic components (2) from the component feeding unit (4) to a given pick-up position, where the electronic components (2) are transferred by the transfer mechanism (11) on to a temporary holder (8) disposed on a draw-out arm (7) of the tray draw-out device (6). Mounting head (5) has a plurality of mounting nozzles (5a), with which the mounting head (5) picks up several electronic components (2) aligned on the temporary holder (8) at a time and mount them on to a circuit board (1) which has been loaded and located at a prescribed position.

A first distance measurement device for measuring a height of the surface of a substrate with respect to a reference plane of a drawing machine which drawing a pattern on the substrate by issuing paste-like material from a nozzle is mounted on a revolution member rotating about the nozzle, and the first distance measurement device is always positioned in the moving direction of the nozzle and measures a height of the surface of the substrate at a slightly preceding position from the nozzle, on the other band a second distance measurement device substantially measures a height of the nozzle from the reference plane, thus, a position of the nozzle is controlled on the basis of both the measured result, and an interval between the nozzle and the surface of the substrate is kept within a predetermined value.

In mounting electronic components (1) from an electronic components pack (5) to a substrate (10), the substrate (10) is put on a table movable horizontally in X-Y directions, and the electronic components (1) are held in through holding holes (3) in a holding plate (2). A selected one of the electronic components (1) is positioned just above a mounting position on the substrate (10) and a pushing pin (23 or 24 or 26) is positioned just above that electronic component (1). Then, the pushing pin (23 or 24 or 26) lowers and pushes the selected electronic component (1) down out of its holding hole (3) to mount it directly onto the substrate (10).

Disclosed is a method of forming a thick film circuit pattern according which involves moving a nozzle having a slit opening above the surface of a stationary substrate with the elongation of the slit opening being oriented at an angle to the direction of movement of the nozzle and forcing a paste in the nozzle downward through the slit opening onto the substrate to deposit a sufficiently wide and uniformly thick film strip. Preferably, the surface irregularities of the substrate are detected without contacting it for controlling the position of the slit opening above the substrate so that it follows closely parallel with the surface contour line of the substrate.
摘要:
A component mounting apparatus comprises a hollow rod communicated to a source of vacuum and having a suction head for picking up generally rectangular articles one at a time by the effect of a suction force. At least one pair of finger members for clamping and releasing the articles which has been sucked onto the suction head are provided for effecting a correction in position of the article relative to the suction head. Each of the finger members has an inclined end face which is adapted to support the article sucked onto the suction head from below in engagement with the opposite lower edges of the article.

A component mounting apparatus for mounting a plurality of components on a board. The apparatus is provided with a board holding device for holding the board at a board holding position, a first mounting head for holding and taking out a component fed from a first component feeding position and mounting the component on the board held at the board holding position, a second mounting head for holding and taking out the component fed from a second component feeding position and mounting the component on the held board, and a component feeding device having a wafer holding table for holding a wafer on which the respective components are fed so that the wafer holding table can be moved reciprocationally between the first component feeding position and the second component feeding position.
摘要:
In a flux transfer unit to be used in an electronic component mounting apparatus for transferring flux to an electronic component picked up from a component feed unit and then mounting the electronic component onto a board, a blade holding head which has a first blade and a second blade for film formation use and scraping use of flux, respectively, and which is reciprocatively driven by a rodless cylinder via a drive transmission pin, is held by a movable member so as to be swingable about a swing support pin, and the movable member is braked with a specified braking force by a plate spring member. Thus, each time the direction of motion of the blade is reversed, the blade holding head swings, so that the first blade and the second blade can be automatically switched over without providing any exclusive drive mechanism.
