Description

[Detailed description of the invention] Industrial field of application This invention is used in an automatic electronic component insertion machine that mounts electronic components onto a board using a tape containing electronic components such as ICs, capacitors, and resistors in parallel. This invention relates to a cart used when converting a tape feeder into a unit and replacing this unit.

Prior Art Conventionally, tape feeders were manually centered one by one by an operator and installed in a predetermined position on the machine stand of this machine.

Problems that the invention aims to solve: Since each piece was attached by hand in this way, it takes time and effort to attach multiple pieces, which is inefficient, and the machine stops during that time, resulting in a drop in production. It was hot.

Means for Solving the Problem A plurality of tape feeders 9 are made into a unit so that each unit can be replaced from the machine base, and a mounting plate 24 for positioning and mounting the unit 8 and a bracket 21 on the upper surface are provided. A movable table having casters 18 on the lower surface and a mounting plate 24 are mounted on a bracket 2.
4 crank levers 2 supported at bending points on 1
2 is rotatably connected at the end of the upper arm, and 2 each on both sides.
The lower arm ends of the crank levers 22 are pivotally connected by a connecting rod 23, and a handle 28 is attached to a supporting shaft 27 integral with the corresponding crank levers 22 on both sides, and the height of the mounting table 24 is adjusted by rotating the handle 28. It is designed so that it can be adjusted.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. The electronic component automatic insertion machine is equipped with a table 2 near the front of the top surface of the machine base 1, whose position is controlled by NC in two directions, the X-axis and the Y-axis, within a horizontal plane. The array is fixed. A rotatably indexable disc member 4 is provided on the rear side, and a large number of vacuum suction cylinders 5 are vertically attached to the disc member on the same circumference. They are each connected to a vacuum source (not shown), and are sequentially rotated from a chip receiving position to a mounting position on a substrate on the table 3, and then to a receiving position.

At the back of the disc member 4 of the machine base 1, a unit base 8 is fixed with bolts, and is positioned by stoppers 6a and 6b in the width direction and by stoppers 7a and 7b in the front and rear direction.On this unit base 8, electronic components are mounted. chip,
Tape feeder 9 that supplies capacitors, resistors, etc.
A large number of replaceable vacuum suction cylinders 5 are arranged radially at predetermined positions corresponding to the vacuum suction cylinders 5.

The tape feeder 9 has chips and the like lined up at regular intervals on a support rod 11 protruding rearward from a feeder frame 10, and a tape roll pasted between two pieces of tape with perforations perforated on the sides for feeding. 12 is supported and the tape is intermittently fed by a sprocket between the guide plates. Then, in front of the vacuum suction tube 5, the tape on the front side is peeled off to expose the chip, and the chip is adsorbed to the vacuum suction tube 5 by the push-up rod.The tape on the front side is wound onto the roll 13, and the tape on the back side is pushed downward. Sent. The intermittent rotation of the tape peeling roller and sprocket on the front side is controlled by a lever 14 protruding forward of the feeder frame 10.
This is performed by being swung up and down by an operation plate that is moved up and down intermittently by a drive device (not shown).

The tape feeder 9 is mounted with a tape roll 12 containing predetermined electronic components depending on the type of the board 3, and is mounted and stored radially on an arcuate unit stand 8 in a standby position. Trolley 16
As shown in FIG. 3, four casters 18 are attached to the bottom plate 17, and the top plate 20 is supported by a plurality of pillars 19. Brackets 21 are attached to the four corners of the top plate 20, and are each pivoted by a support shaft in the same direction at a bent portion of a crank lever 22. The two lower arm ends on the right side and the left side of this crank lever 22 are rotatably connected by a connecting rod 23, and the upper arm end has pieces 25 fixed at two locations on which the unit stand 8 is placed and positioned. They are each pivotally connected to pivot joints 26 at the four lower corners of the placing plate 24. The corresponding rear support shafts 27 of the crank levers 22 on both sides are one piece and are integrated with the crank lever 22, and a U-shaped handle 28 is attached to this support shaft 27.
By operating the crank lever 22 up and down,
rotates, and the height of the mounting plate 24 is changed. Rubber wheels 29 are provided on the front side of the upper surface of the bottom plate 17 to be rotatable on a horizontal plane, and guide angles 30 are provided on the left and right sides of the top plate 20. And the bottom plate 17
The front sides of the top plate 20 and the mounting plate 24 are formed in a concave shape to accommodate the unit base mounting portion of the machine base 1.

Operation: The lever 14 is swung up and down, the tape is intermittently fed, and the exposed chips are sucked into the vacuum suction cylinder 5. The disc members are synchronously and intermittently rotated, and the substrate 3
When the position is controlled in X and Y and positioned at a predetermined position, a predetermined vacuum suction cylinder 5 that has rotated to the front
A chip is mounted on a substrate 3 coated with adhesive. Although continuous work continues like this,
Tape feeder 9 can be changed to another type of board
This also requires changes, so carry the empty cart 16 under the unit stand 8, position it using the rubber rollers 29 on both sides, remove the mounting bolts of the unit stand 8, lower the handle 28, and the mounting plate 24 is lifted and the piece 25 engages with the positioning hole in the lower plate of the unit base 8.

In this state, when the handle 28 is further pushed down, the unit base 8 is lifted from the machine base 1 and removed. The cart 16 is moved by pulling the handle 28 and replaced with another second unit pedestal to which the next tape feeder is attached. The handle 28 is lowered to raise the second unit stand 8 to a predetermined height, and the cart 16 is carried into the mounting position. The carriage 16 is positioned in the width direction by rubber rollers 29, the width direction of the second unit base 8 is determined by left and right stoppers 6a, 6b, and the front and rear stoppers 7
After the front and rear positions are determined by a and 7b, the second unit stand 8 is fixed to the machine stand 1 with bolts. Raise the handle 28 of the trolley 16, lower the mounting plate 24, and disengage the piece 25 from the second unit base 8.
6 to the standby position or left at that position.

Effects As described in detail above, the present invention replaceably arranges multiple tape feeders of an electronic component automatic insertion machine on a unit stand, carries this unit stand in and out using a cart, and moves the tape feeders on the mounting plate. Since the height can be freely adjusted and replaced, the tape feeder can be replaced accurately and reliably, and the replacement time is shortened, which greatly reduces machine downtime and improves work efficiency. .
