摘要:
A mounting apparatus for mounting electronic components, includes a component feeding section wherein plural component feeding units accommodating plural components and sequentially supplying components to a predetermined component take-out position are arranged on a moving table along a moving direction, a positioning mechanism of a mounting member to which one component is to be mounted, and a mounting device for holding one component at a predetermined position in the feeding section and mounting the component onto the mounting member. The mounting device includes a movable member which is vertically movable and has a gas groove which is formed at an inside part of the movable member, and a rotary member which is rotatable around a vertical axis of the movable member and has at its inside part a gas groove which is formed at an inside part of the rotary member and is communicated with the groove of the movable member so as to transmit gas between the grooves during operation. The mounting device also includes a pressure gas transmitting member having positive and negative pressure holes of gas passages formed at its inside, and a gas switching member having a gas groove communicating with a suction passage of a suction member for sucking the component. The switching member is movable to selectively switch between states where the suction passage is communicated with the positive pressure hole and the negative pressure hole, respectively.

There are disclosed an apparatus for mounting electronic components, with which the electronic components can be reversed, up and down, and mounted onto a circuit board in a short mounting process time by performing picking up, delivering and receiving of components between heads, and mounting of the components onto the circuit board in parallel. A plurality of reverse-supply heads are mounted on a component supply holder for performing indexing rotation, while a plurality of mounting heads are mounted on a component mounting holder for performing indexing rotation in synchronization with the indexing rotation of the component supply holder. By (i) picking up an electronic component, (ii) delivering the electronic component from the reverse-supply head to the mounting head, and (iii) mounting the electronic component onto the circuit board at prescribed positions, operations from (i) to (iii) can be carried out in parallel. Thus, the electronic components can be mounted onto the circuit board in a short process time.

An electronic component mounting apparatus includes a plurality of pickup nozzles (1) which are attached to the periphery of a rotary table, that intermittently rotates. The apparatus also includes a cylindrical cam (105) having a cam groove (106, 107a, 107b) which allows the pickup nozzles (1) to move up and down. A first roller (5) is attached to a first slide portion (4a), which is equipped with the pickup nozzles 1. The first roller runs within the cam grooves (106, 107a, 107b) to make the pickup nozzles 1 move up and down. A second roller (6) is attached to a second slide portion 4b, which is attached to the pickup nozzles (1). The second roller runs within the cam grooves (106, 107a, 107b) to make the pickup nozzles move up and down together with the first roller. Also, springs (9) are provided for biasing the first and second rollers (5, 6) into contact with the two side surfaces, respectively, of the cam grooves (106, 107a, 107b).
摘要:
An electronic component feeder is provided for feeding electronic components in their stable position into an electronic component mounting apparatus and allowing the taking up of a top tape with high stability thus increasing the speed of component mounting action. As the top tape (4) is being taken up on a reel (42), a shutter (34) moves backward together with a slit (51) provided integral on the shutter (34). The turning in the tape take-up direction of the reel (42) is driven by the restoring force of a return spring (39). When the reel (42) has completed its take-up motion, the electronic component (1) can be picked up at a component pick-up location with the shutter (34) staying backward. A stationary roller (31) is provided between the slit (51) and the reel (42) and a movable roller (32) is provided for keeping the length of the top tape (4) between the slit (51) and the stationary roller (31) substantially constant.
