Description

The present invention relates to a storage method, a storage plate, and a storage device for storing parts in a plurality of storage holes provided in the storage plate in order to facilitate the handling of the parts.

A method of storing the parts is described in, for example, WO2018 / 105591 (Patent Document 1). In Patent Document 1, a storage plate having a plurality of storage holes is prepared, a plurality of parts are put on the storage plate, and in that state, the storage plate is oscillated around a predetermined axis and the axis is concerned. A method of swinging a plurality of parts into each storage hole while moving them on a storage plate by vibrating in a direction is described.

WO2018 / 105591 Japanese Unexamined Patent Publication No. 9-136716

In the method described in Patent Document 1, the component on the storage plate slides on the surface of the storage plate. Therefore, the plurality of parts move as a lump on the storage plate while being repeatedly rolled and agitated based on gravity while physically rubbing against the surface of the storage plate. Then, among the moving parts, those aligned with the storage hole are put into the storage hole.

In the storage method described above, there is a concern that problems such as dirt on the part due to friction with the surface of the storage plate, cracking or chipping of the part due to the impact of rolling or dropping due to gravity on the part may occur.

Further, there is a limit to increasing the number of parts that can be received in the pockets provided along the circumference of the rotating plate by using the method described in JP-A-9-136716 (Patent Document 2), and the grid pattern is used. In order to arrange the parts in the space, there is a problem that a new process of holding and positioning each part is required.

That is, in order to increase the number of processed parts, it is conceivable to increase the rotation speed of the rotating plate, but if the rotation speed is increased, the impact force between the pocket and the parts also increases proportionally. As a result, there is a problem that the occurrence rate of cracked or chipped parts increases.

An object of the present invention is to provide a storage method, a storage plate, and a storage device capable of aligning a plurality of parts without causing stains, cracks, and chips of the parts to be handled.

The storage method according to one aspect of the present invention includes a first step of preparing a storage plate having a first main surface and having a plurality of storage holes provided on the first main surface, and the first step of the previous stage storage plate. A second step of placing a plurality of parts on one main surface, a third step of moving a plurality of the parts on the first main surface by applying acceleration to the plurality of parts, and a plurality of the parts. The first main surface is provided with a fourth step of inserting at least a part of the gas into the storage hole, and the gas is discharged from a plurality of gas paths through which the gas is provided on the first main surface. The plurality of said parts are moved.

(First Embodiment)
With reference to FIGS. 1 to 6, a storage method according to the first embodiment of the present invention and a modification thereof, and a configuration of a storage plate 11 and a storage device 1 will be described.

As shown in FIGS. 1 and 2, the storage device 1 includes a storage plate 11, a main chamber 31, and an acceleration imparting device 71, and the storage device 1 further includes a gas supply device 51 and a controller 91. I have. Each of the storage plates 11 is provided with a plurality of storage holes 13 in which the parts 101 (see FIG. 2) can be stored. It should be noted that FIG. 1 does not show all the plurality of storage holes 13 actually provided, but schematically shows them. Each storage hole 13 has an opening 14, a bottom surface 15, and a side surface 16. When the first main surface is viewed in a plan view, when the component 101 has a rectangular parallelepiped shape, the shape of the storage hole 13 is preferably a substantially rectangular shape according to the shape of the component 101, and the bottom surface 15 has a rectangular shape. Is preferable. The plurality of storage holes 13 are arranged in a grid pattern along a first direction (row direction) along the first main surface 18 and a second direction (column direction) along the first main surface 18 and orthogonal to the first direction. It is provided. Further, a frame portion protruding from the first main surface 18 may be provided on the peripheral edge of the first main surface 18 of the storage plate 11. The frame portion can prevent the component 101 placed on the first main surface 18 of the storage plate 11 from falling off from the storage plate 11.

Although not shown, the storage plate 11 may have a structure in which an upper plate portion having a through hole forming the side surface of the storage hole 13 and a lower plate portion forming the bottom surface of the storage hole 13 are combined. Good. When the dimensional conditions of the component 101 are different, the optimum dimension of the storage hole 13 for the component 101 is also different. If different types of upper plate portions are prepared, it is possible to quickly respond to changes in the dimensional conditions of the component 101 by using the common lower plate portion.

In this embodiment, one component 101 is inserted into each storage hole 13. When the part 101 transferred into the storage hole 13 is a part as a finished product, a plurality of parts 101 are held in a grid pattern on the storage plate 11, so that the part can be measured, for example, in a measuring process or packed. Convenience is provided when supplying to the process. Further, when the component 101 transferred into the storage hole 13 is a chip-shaped electronic component body before the external electrode is formed, the plurality of electronic component bodies are aligned and held on the storage plate 11. , Convenience is provided when supplying the component body to the process for forming the external electrode.

As shown in FIGS. 2 and 3, the storage device 1 can include a main chamber 31 that also serves as a base for supporting the storage plate 11. The main chamber 31 having the main space 32 supports the storage plate 11. When the storage plate 11 is supported by the main chamber 31, the main space 32 of the main chamber 31 forms an internal space closed by the second main surface 19 of the storage plate 11. As shown in FIGS. 1 and 2, a tilting mechanism portion 71A including a rotating shaft and a rotating machine is connected to the main chamber 31. The tilting mechanism portion 71A can also be connected to the storage plate 11.

In the following description, as shown in FIGS. 1 and 2, the X-axis direction and the Y-axis direction that are orthogonal to each other in the horizontal plane, and the Z-axis direction that is orthogonal to the X-axis direction and the Y-axis direction are defined. May be used.

In carrying out the storage method, first, as shown in FIGS. 1 to 3, a storage device 1 including a storage plate 11 is prepared. A plurality of parts 101 are placed on the first main surface 18 of the storage plate 11. This state is schematically illustrated in FIG. 4 (1). As can be seen from FIG. 4 (1), the plurality of parts 101 are brought closer to the left end portion in the drawing of the first main surface 18 of the storage plate 11.

In FIGS. 4 (1) to 4 (4), an aggregate of a plurality of parts 101 is illustrated as a part group 101A. As an example, the storage plate 11 is arranged in a grid pattern having a plurality of rows and a plurality of columns, and the dimensions of the rectangular openings 14 are 0.65 mm to 0.80 mm in a plan view of the first main surface 18. When the storage holes 13 having a square shape and the spacing between the openings 14 are 0.90 mm are provided, the number of parts 101, which is about 1.5 times the number of the storage holes 13, is on the first main surface 18 of the storage plate 11. Placed in.

The component 101 handled in this embodiment has a chip shape having a substantially rectangular parallelepiped shape. As an example, the component 101 has a plane dimension of 0.6 mm × 0.6 mm.

Next, the air supplied from the gas supply device 51 through the main chamber 31 is discharged from a plurality of gas paths 12 provided on the first main surface 18 of the storage plate 11. As shown in FIG. 4 (1), the component group 101A moves in the direction of the arrow 39 in the X-axis direction along the first main surface 18 of the storage plate 11 in a state where the air is released. Then, in the process of this movement, one component 101 is inserted into each storage hole 13.

As a specific example of the gas supply device 51, an example using a blower will be given. A positive pressure source installed in the manufacturing process may be used. In the embodiment, the gas released from the plurality of gas paths 12 is not limited to air. For example, as the gas, an inert gas such as nitrogen gas or argon gas can be used. As a result, the influence of the chemical reaction between the gas and the component 101 can be reduced. Alternatively, a gas having a predetermined structure of the gas, for example, a gas having reactivity with a specific material of the component 101 can be used. With a gas having a specific reactivity, it is possible to obtain the storage of parts and the processing of parts at the same time. In addition, air having a lower humidity than the atmosphere can be used. At this time, it is preferable that the gas supply device 51 includes a dehumidifying mechanism unit or is connected to the dehumidifying mechanism unit.

When the component 101 moves in the direction indicated by the arrow 39 in FIGS. 4 (1) and 5 and is aligned with the empty storage hole 13, the aligned component 101 enters the storage hole 13.

Here, in a state where air is discharged substantially evenly from the plurality of gas paths 12 provided on the first main surface 18, it becomes difficult for the component 101 to enter the storage hole 13. Therefore, when a predetermined atmospheric pressure is applied, the first flow velocity through the plurality of gas paths 12 provided in the storage hole 13 passes through the plurality of gas paths 12 provided in the first main surface 18 excluding the storage hole. It is slower than the second flow velocity of. As a result, the difference is provided so that the first flow velocity of the air coming out of the storage hole 13 is relatively slower than the second flow velocity of the air coming out of the first main surface 18 located around the storage hole 13. Due to this relative difference in flow velocity, the component 101 can easily enter the storage hole 13. Further, the first atmospheric pressure acting on the gas passing through the plurality of gas paths 12 provided in the storage hole 13 acts on the gas passing through the plurality of gas paths 12 provided on the first main surface 18 excluding the storage hole. It is preferably lower than the second atmospheric pressure.

The storage plate 11 preferably has a structure in which the air permeability in the storage hole 13 is lower than the air permeability in the first main surface 18 excluding the storage hole 13. Further, it is more preferable that the air permeability of the storage hole 13 is lower than that of the first main surface 18 located around the storage hole 13.

Further, in the storage plate 11, the first area ratio in the storage hole 13 is the second area in the first main surface excluding the storage hole in the area ratio of the gas path 12 per unit area when the first main surface 18 is flat. A configuration lower than the ratio is preferable.

The storage plate 11 preferably has a plurality of gas paths 12 composed of a plurality of through holes connected to the first main surface 18 and the second main surface 19. Further, a configuration having a porous portion in which a large number of pores are connected to each other is preferable. The storage plate 11 is preferably configured such that the porous portion is provided at least on the first main surface 18 and a part of the storage hole 13 so as to be connected to the main space 32 of the main chamber 31. The structure in which the storage plate 11 is formed of a porous material is most preferable because the structure is simple and the production is easy.

In this embodiment, one component 101 is inserted into one storage hole 13. In this case, the depth dimension of the storage hole 13 is substantially the same as the length dimension of the longest side in the external dimension of the component 101. With this configuration, not only can the inconvenience of the component 101 being transferred into the storage hole 13 and then jumping out again can be reduced, but also the upper surface and the first main surface 18 of the component 101 that have entered the storage hole 13 can be reduced. The parts 101 are aligned with each other with the step between them reduced. Next, the component 101 that has entered the storage hole 13 supports the component 101 that is going to pass over the storage hole 13, and functions to make the movement path of the component 101 that is going to pass flatter. Therefore, the subsequent component 101 can be smoothly moved on the storage plate 11. This effect becomes more remarkable when the component 101 has a rectangular parallelepiped shape as in this embodiment.

As a result of the movement of the component group 101A shown in FIG. 4 (1) in the direction of the arrow 39, as shown in FIG. 4 (2), the component group 101A is located on the right side of the first main surface 18 of the storage plate 11. It is sent. Since a plurality of parts 101 are inserted into the storage holes 13 during this movement, the number of parts 101 reaching the right side portion of the first main surface 18 of the storage plate 11 is less than the total number of parts 101. There is. Normally, at this stage, not all the storage holes 13 are filled with the parts 101, but some empty storage holes 13 without the parts 101 are left.

Next, in order to insert the component 101 into the storage hole 13 left empty, the component group 101A is in the opposite direction to the above on the storage plate 11 as shown by the arrow 40 in the X-axis direction in FIG. 4 (2). Moved to. In the middle of the movement of the component group 101A in the direction of the arrow 40, the component 101 is inserted into the storage hole 13 in which the component 101 is not stored.

The time for carrying out the moving step in the direction of arrow 40 described above is usually shorter than the time for carrying out the moving step in the direction of arrow 39 described above. In other words, the moving speed in the direction of arrow 40 is higher than the moving speed in the direction of arrow 39. At the stage of carrying out the moving step in the direction of the arrow 40, the number of parts 101 left without being transferred into the storage hole 13 is less than the number of parts 101 initially inserted. Such a change in moving speed is achieved by increasing the vibration component in the X-axis direction, which increases the acceleration given to the component 101 by the acceleration giver 71. As an example of increasing the acceleration, it can be achieved by tilting the storage plate 11 so that the tilt angle drive controlled by the controller 91 increases the tilt angle of the storage plate 11.

As a result of the movement of the component group 101A shown in FIG. 4 (2) in the direction of the arrow 40, as shown in FIG. 4 (3), the component group 101A is located on the left side portion of the first main surface 18 of the storage plate 11. It is sent. Even at this stage, some storage holes 13 that remain empty may be left, and if it is necessary to store the parts 101 in all the storage holes 13, the arrow 41 is shown in FIG. 4 (3). The component group 101A is moved in the direction, and as shown in FIG. 4 (4), the component group 101A is relocated to the right portion of the first main surface 18 of the storage plate 11. Further, if necessary, the switching of the moving direction of the component group 101A may be repeated.

Further, in the present embodiment, the air is discharged from the first main surface 18 of the storage plate 11 and the plurality of gas paths 12 provided in the storage holes 13 along the first main surface 18 of the storage plate 11. The component group 101A moves, and then the component 101 is inserted into the storage hole 13. Due to the air blowout, the component 101 is cracked or chipped due to the impact between the first main surface 18, the storage hole 13 and the component 101, or the component 101 is contaminated due to physical friction with the first main surface 18. Can be reduced. Even if the loading ratio of the number of parts 101 to the storage holes 13 is high, it is possible to suppress the occurrence of cracks, chips, and stains on the parts 101.

In the embodiment described above, the storage plate 11 is driven by the acceleration giver 71 having the tilt mechanism portion 71A capable of controlling the tilt of the storage plate 11 so as to change the tilt to a predetermined tilt. As a result, the storage plate 11 can be controlled to have a desired inclination with respect to the horizontal plane. The embodiment of the present invention is not limited to the acceleration giver 71 having the tilting mechanism portion 71A. For example, in the modification shown in FIG. 6, the acceleration giver 71 further has a blower portion 71B using a blower that supplies air to the first main surface 18 in addition to the tilt mechanism portion 71A. The blower portion 71B can give acceleration to the component 101 on the first main surface 18 to move the component 101 on the first main surface 18. Further, the acceleration imparting device 71 may include a magnetic field generating portion capable of generating a magnetic field on the first main surface 18. The acceleration giver 71 may include at least one configuration selected from the group consisting of the tilting mechanism portion 71A, the blower portion 71B, and the magnetic field generating portion.

Further, in the above-described embodiment, in the step of transferring the plurality of parts 101 into each storage hole 13, the configuration in which one component 101 is inserted into one storage hole 13 makes the alignment interval of each component 101 highly accurate. It is preferable because it can be obtained in. However, when the processing speed of the process is determined rather than the accuracy of the alignment interval of each component 101, it may be preferable that the plurality of components 101 are inserted into one storage hole 13.

Here, a case where the embodiment of the present invention is applied in the firing step carried out for manufacturing the ceramic part will be examined. In the firing step, a large number of raw ceramic elements as parts 101 are fired at the same time. At this time, it is important to arrange a large number of ceramic elements at uniform densities or intervals without damage so that firing unevenness does not occur in a large number of raw ceramic elements. By applying the embodiment of the present invention, the physical contact or frictional force between the component 101, which is a raw ceramic body having low strength before firing, and the storage plate 11 can be reduced, and a plurality of storage holes 13 can be applied. The density or spacing of the raw ceramic elements as an appropriate number of parts 101 placed therein can be easily maintained. This allows a large number of raw ceramic elements to be placed in the firing furnace with reduced damage and kept in a predetermined alignment. As a result, it is possible to obtain a large number of fired ceramic bodies that are less affected by fluctuations in the alignment position and have less damage.
