Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit board carrier device (hereinafter simply referred to as a carrier device) used in a mounting machine for mounting electronic components on a circuit board (hereinafter simply referred to as a substrate).

[0002]

2. Description of the Related Art In recent years, there has been a strong demand for high-speed and high-efficiency transfer devices used in mounting machines in order to improve productivity.

A conventional conveying device will be described below with reference to the drawings. FIG. 5 is a perspective view of a main part of a conventional mounting machine. In FIG. 5, 26 is an X-direction mobile robot having a fixed base, 27 is a Y-direction mobile robot, and 14 is a mounting head attached to the Y-direction mobile robot 27 and having a nozzle 15 for sucking an electronic component 16. 28 is a substrate carry-in section of the carrier, 29 is a board carry-out section, and 30 is a board 3
3 is a support table having a stopper 32 for stopping 1 at a predetermined position.

The operation of the carrier of the mounting machine configured as described above will be described below. First, the X-direction mobile robot 26 moves the Y-direction mobile robot 27 to a predetermined position in the X-direction. Furthermore, the Y direction mobile robot 27
Thus, the mounting head 14 is moved in the Y direction to position the electronic component 16 sucked by the suction nozzle 15.

On the other hand, the substrate 31 coming from the substrate loading section 28 is loaded into the support table 30 and stopped at a predetermined position by a stopper 32 provided on the support table 30. Then, the electronic component 16 is mounted on the substrate 31. next,
After the mounting is completed, the stopper 32 is lowered and the substrate 31
Substrate to the left side of the support table 30 and the substrate unloading section 2
Carry out from 9.

[0006]

However, in the conventional structure as described above, there is a problem that the board cannot be mounted during the board moving in and out, so that the mounting efficiency is poor and the productivity is low. I had.

In view of the above problems, it is an object of the present invention to provide a highly efficient transporting machine for a mounting machine which eliminates the time during which the mounting machine cannot be mounted.

[0008]

In order to achieve the above-mentioned object, a carrying apparatus of the present invention carries two or more two-stage tables having a carrying means and a stopper at an upper stage and a carrying means at a lower stage. Arranged in series with respect to the direction, the table is movable in the vertical direction, and the table is configured to match the mounting surface of the mounting machine when the height of the upper stage rises and the height of the carry-in route and unload rail when descending Is.

[0009]

According to the above construction, when there are two tables, for example, when one table is raised and electronic components are mounted on the mounted substrate, the lower part of this table is passed and the other table is passed. It is possible to prepare a board that has not been mounted yet, and since the board that has been mounted can be carried out while passing through the lower part of the other table while mounting the board that has not been mounted, it is possible to mount even while the board is being transported. Efficiency is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A carrying device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a carrying device in this embodiment. In the figure, reference numeral 1 is a carry-in rail provided with a belt for carrying a substrate on its side surface, and 2 is a similar carry-out rail. Three
Is a first table for supporting the substrate at the time of mounting, rails 4, belts 5, support plates 6, stoppers 7 are provided on the upper stage thereof, and a belt (not shown) is provided on the lower stage thereof. 8
Is a second table having the same configuration as the first table 3, and has a rail 9, a belt 10, a support plate 11 and a stopper 12 on the upper stage, and a belt 13 on the lower stage. Then, the first table 3 and the second table 8 respectively move in the vertical direction, and in the raised state, the lower part is arranged so that the board arranged in the upper part is aligned with the surface on which the electronic parts of the mounting machine are mounted. The heights of the carry-in rail 1 and the carry-out rail 2 are the same so that the board can be carried in and out.
Further, both the tables 3 and 8 are configured such that, when the tables 3 and 8 are lowered, the upper portions of the tables 3 and 8 have the same height as the carry-in rail 1 and the carry-out rail 2 so that the board can be carried in and out.

FIG. 2 is a schematic cross-sectional view for explaining the operation of the above-mentioned transporting device, showing the first table 3 in a raised state and the second table 8 in a lowered state.

When the first table 3 descends, the belt 5 at the position A moves to the position B, and the lower belt at the position B moves to the position C indicated by a chain double-dashed line. On the other hand, when the second table 8 is raised, the belt 10 at the position E is
Moves to the position D indicated by the chain double-dashed line, and the lower belt 3 at the position F moves to the position E. Then, in a state in which these tables 3 and 8 are respectively raised, the electronic components 16 adsorbed to the tips of the nozzles 15 of the mounting head 14 that can move in the X and Y directions are mounted on the substrates 17 and 18, 18 can be implemented.

Next, an example of the method of carrying the substrate will be described with reference to the schematic cross-sectional views of the essential parts of the carrying device shown in FIGS. 3 and 4, 19 and 20 are the upper and lower steps of the first table, 21 and 22 are the upper and lower steps of the second table, and 23,
Reference numerals 24 and 25 are substrates.

First, as shown in FIG. 3 (a), the board 23 carried in from the carry-in rail 1 is stopped at a predetermined position by a stopper at the upper stage portion 19 of the first table in the lowered state. Then, as shown in FIG. 3B, the first table is raised and mounting is started. Next, as shown in FIG. 3C, the next board 24 is carried in from the carry-in rail 1 to the upper stage part 21 of the second table passing through the lower stage part 20 of the first table, Stop in place with a stopper. Then, as shown in FIG. 3D, the second table rises and waits for the mounting of the board 23 of the first table to be completed.

Next, as shown in FIG. 4A, the substrate 23
When the mounting of (1) is completed, the first table descends and the mounting of the board 24 of the second table is started. And FIG. 4 (b)
As shown in FIG. 5, the board 23 passes from the lowered upper stage portion 19 of the first table to the lower stage portion 22 of the second table, passes through the carry-out rail, and is carried out from the mounting machine. Then, a new substrate 25 is loaded again, and the upper stage 1 of the first table 1
Stop at 9. Next, as shown in FIG. 4C, the first table rises and waits for the mounting of the board 24 of the second table to be completed.

Then, as shown in FIG. 4D, the second table descends after the mounting of the board 24 is completed, and the board 24 is carried out through the post carry-out rail 2 and is transferred to a new board 25. Implementation is started. By repeating the board transport cycle in this manner, the mounter can mount electronic components without stopping during loading and unloading of the board.

Although the number of tables is two in this embodiment, the present invention is not limited to this.
You may arrange | position three or more tables in series with respect to the conveyance direction of a board | substrate between a carrying-in rail and a carrying-out rail.
