摘要:
A component mounting method, and an apparatus therefor, which includes the steps of causing a plurality of suction nozzles, supported for intermittent movement along a predetermined path in synchronism with each other, to receive electric components at a component receiving station and then to transport them towards a component mounting station, and effecting both the rectification of the position of each component in two directions perpendicular to each other and the angle adjustment of the respective component during the successive transportation of the components towards the component mounting station. Both the rectification of the position and the angle adjustment of each component are carried out while the associated suction nozzle is held still at a certain station, and electric characteristics of each component are checked during the rectification.

A parts mounting apparatus has a plurality of suction nozzles for picking up and holding the parts, the nozzles intermittently moving along a closed path to stop positions arranged at predetermined set intervals along the path, including a parts pickup position at which parts are picked up by the suction nozzles and a parts mounting position at which parts are mounted on an article on which parts are to be mounted. A position adjusting device is provided between the parts pickup positions and the parts mounting position for adjusting the position of a part held on a suction nozzle to orient the part relative to the longitudinal axis of the suction nozzle in two directions at right angles to each other and perpendicular to the longitudinal axis of the nozzle. A parts posture detecting device is provided at a stop position downstream of the position adjusting device and which has a line sensor for detecting whether the posture of the parts relative to the suction nozzle axis is proper by sensing whether or not a part extends beyond a maximum position past the end of the corresponding nozzle. The suction of the suction nozzle is controlled for retaining or releasing the parts in accordance with whether the posture detecting device had detected that the part held by a nozzle is proper or not.

In an electronic chip placement machine with test function, there is provided a suction nozzle for holding a chip, a chip-regulation device for regulating the attitude of the chip by clamping the chip at portions having no electrodes probes for testing electrical characteristics of the chip. The tip portion of the suction nozzle is made of an insulating material such as a ceramic or a synthetic resin in order to avoid a short-circuit between electrodes of the chip through the nozzle. Therefore, the electrical characteristics of the chip can be tested without the separation between the nozzle and the chip. Furthermore, since one cycle of the operational process according to the present invention is shorter than that of the conventional operational process, it is possible to provide chip-test and placement machines whose structure is simple. As a result, productivity and durability can also be increased.

An automatic board transfer apparatus transfers, positions and delivers boards and comprises an arm which is reciprocable along guides for horizontally guiding the boards and which is vertically movable perpendicularly to the plane of the boards. A pusher and a pin are installed on the arm. The board is transferred in advance along the guides by the pusher and on the way a pin is inserted into the reference hole of the board to thereby transfer the board. Thus, variations in the position of the reference hole of the board caused by reversing the board and variations in board length are accommodated without adjustment, thus making continuous production possible.

The present invention has for its object to provide an apparatus and a method for transferring boards, and a component mounting apparatus whereby a production efficiency can be improved in accordance with types of boards to be produced. For accomplishing this object, there are arranged a shift device capable of moving a mounted board from a process-finished board transfer path to an unprocessed board transfer path, a controller for controlling this moving, and an identifying device. This arrangement enables switching of a method of transferring boards in accordance with types of boards to be produced, and controlling supply of boards to the component mounting apparatus, so that production efficiency is improved in accordance with types of boards.

A component feeding device (1) comprises a first feeder table (7) provided with a plurality of component supply units (6) aligned in parallel rows thereon, and arranged for movement in a direction of the parallel alignment, a second feeder table (8) provided with a plurality of component supply units (6) aligned in parallel rows thereon, and located behind the first feeder table (7), and a transfer unit (9) for receiving and conveying supplementary components from the component supply units (6) on the second feeder table (8) to a predetermined component feeding position. When a certain group of the components on the first feeder table (7) has been exhausted, their new supplies are picked up from the second feeder table (8) by the transfer unit (9), conveyed to the component feeding position, and placed on a board (5), thereby eliminating necessity for providing waiting spaces for feeder tables (7, 8) in a flow direction of boards (5) and increasing productivity with a compact arrangement.

When a movable member (14) is moved from a gripping position in which a circuit board (2) was gripped by the movable member (14) and a stationary member (13), a separation mechanism (7, 12) forcibly separates the circuit board from the stationary member (13), to thereby prevent the occurrence of a state in which the circuit board (2) is stuck to the stationary member.
摘要:
A positioning system for a circuit board having a reference positioning hole. The positioning system has a table on which the circuit board is placed and a positioning pin unit. The positioning pin unit has a plurality of nested positioning pins, each having a different pin diameter, and a plurality of springs each supporting at least one of the plurality of nested positioning pins. The circuit board, which is placed on the table, is positioned by inserting into the reference positioning hole that positioning pin having a diameter substantially matching the diameter of the reference positioning hole.
