Description

Component transfer device

The present invention relates to a component transfer device, in particular, to reduce the moving distance of the head portion to be mounted by mounting the parts as possible and at the same time to enable parallel and continuous processing to reduce the component mounting time and increase the component mounting accuracy Relates to a device.

The recent miniaturization of electric and electronic products has led to higher density, miniaturization, and diversification of electronic components. Therefore, the use of Surface Mounting Technology (SMT) for the production of printed circuit board (PCB) assembly is accelerating. The surface mounting technology is largely classified into the development of a surface mounting device (SMD) and the development of an assembly technology of the surface mounting component. Compared to conventional through-hole type electronic components, the surface mount components are not only compact in size but also have high mounting accuracy when mounted on a printed circuit board. Since both sides of the printed circuit board can be used, the demand for developing small electronic products is increasing rapidly.

In general, a production line for assembling surface-mount components on a printed circuit board is composed of several kinds of devices. Specifically, a substrate supply for supplying a printed circuit board to a line, a screen printer for applying solder paste onto a pattern before mounting a component, a surface mounter for mounting a component to a substrate, and a substrate A dispenser for applying an adhesive to prevent the component from moving before the mounted component is fixed, an oven for connecting the component and the pattern by melting the applied solder fast after the surface mounter has mounted all the components on the substrate; And a device for removing the assembled board from the line. And each device constituting the production line is connected via a conveyor, the work substrate that has completed the work in each device is transferred to the next device through the conveyor.

1 and 2 show an example of a surface mounter, and as shown therein, a conventional XY table structure component mounting apparatus includes an X, Y axis (3, 4) and an X axis having a moving ability on a rectangular coordinate. (3) a head portion (1) having a mechanical structure attached to and mounted on the component, a feeder (feeder) for supplying the component to the head portion (1), and a mounting state of the component in the head portion (1). The inspection means (5) for inspecting the, and the printed circuit board (6) on which the component is mounted is composed of six parts, and a nozzle and a tool (TOOL) exchange device may be additionally added.

Conventionally, the component mounting apparatus of the XY table structure has a structure having power on the X, Y axes (3, 4) so as to move on the table on an orthogonal seat, and the Y axis (4) is the X axis (3) in the Y axis direction. And the X-axis 3 moves the head portion 1 coupled on the X-axis 3 in the X-axis direction. The head 1 for mounting and mounting the component can be moved to a desired position on the XY table. As a result, the head 1 is supplied with the component from the feeder 2 to the printed circuit board 6. Will be mounted. The head part 1 moves to a nozzle replacement device or a tool replacement device installed in an area in which the head part 1 is movable in order to replace the nozzle and tool according to the characteristics of the component to be mounted, and replaces the nozzle and tool.

However, in the conventional XY table structure as described above, at least three positions of the printed circuit board where the head part 1 is the feeder 2, the inspection means 5, and the parts are mounted to adsorb and mount the parts. You must move, and operations at each location can only perform part of the overall process. Accordingly, the time required by the head movement constituting the head unit 1 and the parallel processing of each operation are excessive, and the time required for the entire processing process is excessively generated, and a method of employing a plurality of heads is applied to compensate for this. In addition, only one head constituting the head portion 1 is operated, and only a slight reduction in the head position movement time is obtained. In addition, the increase of the head 1 moving trajectory causes a cumulative position error, which negatively affects the precision of component mounting.

Accordingly, an object of the present invention is to provide a component transfer device that can shorten the moving distance of a head mounted to mount a component as much as possible and at the same time enable parallel and continuous processing to reduce component mounting time and increase component mounting accuracy. .

In order to explain the operation of each part, the operation of the part acquisition / transfer nozzles 13 and 14 used for the part acquisition / transfer and the guide and trailer operation used in the part transfer process will be described first.

In the embodiment of the present invention, the component acquisition nozzle 14 and the component transfer nozzle 13 use the same structure, and the structure thereof is shown in FIG. 13 (hereinafter referred to as a transfer nozzle).

The transfer nozzle can exchange the nozzle front end 24 according to the characteristics of the part and the user's purpose. In the case of FIG. 14A, when the outer cylinder 25 and the inner cylinder 26 are combined, the outer cylinder vent 32 It is closed by the outer surface of the inner cylinder 26 and the inner cylinder vent 34 is connected to the outer cylinder inner groove 31 so that the pneumatic pressure supplied from the pneumatic hose 28 passes through the nozzle hole 30 to the nozzle front end portion ( 24) can be adsorbed parts. In the case of FIG. 14B, when the inner cylinder 26 is separated from the outer cylinder 25, the inner cylinder vent 34 is closed by the inner surface of the outer cylinder 25 so that the pneumatic pressure supplied from the pneumatic hose 28 is blocked. The inner cylinder outer groove 33 is connected to the outer cylinder vent 32 so that the pneumatic pressure of the inner space of the outer cylinder 25 is discharged to the outside to lose the component adsorption force. As such, the two-cylinder interaction of the transfer nozzle performs suction and removal of parts without a separate valve. The delivery process of the part is shown in FIG. 15, and when used in the delivery process of the part, the power unit 17 pushes the outer cylinder 25 out and pulls the inner cylinder 26 back in return. Upper feed guide (9), component delivery device (8) In FIG. 15, the parts are transferred from the B side to the A side. In the initial state, the B side outer cylinder 25b and the inner cylinder 26b are coupled to each other. As described above, the component 15 is adsorbed. The A side outer cylinder 25a and the inner cylinder 26a are separated, and pneumatic pressure is interrupted | blocked. At this time, while the B side outer cylinder 25b is separated in the A direction by the B side power unit 17b, the part 15 is in contact with the A side nozzle front end 24a and the A side outer cylinder 25a is connected to the inner cylinder ( It is pressed in the direction of engagement with 26a). At this time, the A side power unit 17a does not operate at all, and as the component 15 moves from the B side to the A side, the A side nozzle cylinders 25a and 26a are engaged (Fig. 14 a) and the B side. The nozzle cylinders 25b and 26b are in a disengaged state (FIG. 14b) so that pneumatic pressure is connected to the nozzle A on the side, and the external cylinder vent is opened at the same time as the nozzle on the B side is blocked. Through this series of procedures, the component 15 is transferred from the B side nozzle to the A side nozzle. Then, the B-side power unit 17b returns to its original position and moves in the B direction. At this time, the inner cylinder guard 27b2 is pulled out and the portion exceeding the distance between the guards 27b1-27b2 is connected to the outer cylinder 25b by the connecting rod 29. ) Is also pulled together. As a result, the final state of the nozzle is inward (in the B direction, in the B direction, A direction in the A side), and as a result, the nozzle on the A side is absorbed in the situation where the parts are located inward. At this time, the connecting rod 29 prevents the outer cylinder 25 and the inner cylinder 26 from being completely separated, and the guide 27 supports the connecting rod and serves to be connected to the power unit 17.

The coupling structure of the guide and the trailer is shown in Figures 9, 10, 11, 12 and the guide rail is the outer rail 18, the linear motor stator 21, the inner rail 19 is coupled in a U-shape and the outer side The outer rollers 22 and the inner rollers 23 of the trailer 10 are positioned between the rails 18 and the inner rails 19, and the rollers 22 and 23 are formed by roller connecting shafts 50 which are elastic in the A direction. The trailer abuts against the inner surfaces of the rails 18, 19. This structure by the roller connecting shaft 50 serves to stably support the trailer against the bending of the guide rail having a certain curvature. (See FIG. 9) The trailer 10 is driven by the power of the linear motor. Moving along 18 and 19, the movement and position of each trailer 10 can be individually controlled, and can be driven only when necessary because it is installed outside the position where the parts are exchanged.

In FIG. 7, the nozzle used in the case of the part acquiring means 11 has the structure shown in FIG. 13, which is the same as the conveying nozzle, and the driving part employs two structures of the acquiring driver 16 and the transmitting driver 17.

In the acquisition process, the parts are moved in the F direction from the conventional tape loading part supply means (2), and the rotating plate of the part acquisition device is equipped with a plurality of nozzles 14, and the basic setting of the nozzles is cylinders 25 and 26. It is in a displaced state and the position is retracted to the center of the rotating plate (C, E direction).

When the specific nozzle is located above the component supply means 2 (position 1), the acquisition power unit 16 located in front of and behind the nozzle guard operates in the same manner and descends together (B direction). ) As the whole descends to the part supply means 2 and the nozzle front end 24 is connected to the part 15 and is pressurized by the continuous descending of the power unit 16, the cylinders 25 and 26 are coupled. At the beginning, the front end of the power unit 16f is separated from the outer cylinder guard and the cylinder is engaged in the state in which the parts 15 are pressed at a constant pressure by continuously lowering the inner cylinder 26 by the power rear end 16r, and the nozzle described above. By pneumatic pressure is applied to the nozzle front end 24 by the operation of to suck the components. After the lowering in the B direction is completed, the acquisition power unit 16 starts the rising in the C direction. At this time, the power code end 16r is separated from the inner cylinder guide and rises, and the power end 16f is brought into contact with the front end of the outer cylinder, thereby maintaining the engagement state of the nozzle cylinders 25 and 26 toward the center of the rotating plate ( C direction) Return. The rotary plate that has obtained the parts is rotated in the A direction so that the acquired parts face the direction of the upper feed guide 9 (position [2]). After the specific trailer on the upper feed guide (9) is reached by the control to transfer the parts to the component transport nozzle 13 of the trailer 10 via the trailer 10 through a transfer process as shown in FIG. do. At this time, the power unit to be used is the transmission power unit, and after completing the transmission, the nozzle in the parts acquisition means 11 is in a cylinder-off state and the position is retracted to the center of the rotating plate.

The upper feed guide 9 moves the trailer 10 to the parts delivery means 8 with the structure and operation of FIGS. 9 to 11 described above, and the parts delivery means 8 are shown in FIG. 8 in the embodiment of the present invention. As shown, it is located under the part delivery means 8 which has been moved from the two front conveying guides 9 forward and backward and is delivered to the nozzle of the trailer 10 on the rotation guide 12 supported by the upper rotating platform 7.

As a result, the rotating plate rotates in both directions (A and B directions). The power unit is not needed when receiving the parts from the parts transfer means 8, and the power unit is used to transfer the parts to the trailers 10 and 10 on the rotation guide 12 (see FIG. 15). Accordingly, each nozzle reciprocates in the C, D, E, F, and G directions.

In the same manner as the component acquisition means 11 and the component delivery means 8, the head rotating plate 43 rotates in the A direction, and the nozzle head 41 which adsorbs the component is installed in the direction in which the image recognition means 40 is installed ( Position [2]), in which the image recognition means 40 measures the angle and position of the component, and then the head rotating plate 43 rotates in the A direction so that the nozzle head 41 can be mounted on the PCB substrate. Move to position (position [3]). At the time when this operation is performed, the entire head part 1 moves to a specific position on the PCB on which the parts are to be mounted by the X and Y drive shafts, and finally, the position is corrected by correcting the adsorption error of the parts measured by the image recognition means 40. The angle of the component is corrected by rotating the nozzle head 41 in the E and D directions, and then mounting the component by lowering the nozzle head 41 in the B direction.
