Description

  The present invention relates to a component fixing jig and a fixing device for fixing various components such as electronic components, and a component transport carrier for transporting various components in a fixed state.

  Conventionally, sealing of packages and lids of electronic components such as piezoelectric vibrators and semiconductor elements has been performed by seam welding. This seam welding is generally performed by placing a lid on the opening of the package and then applying a pulsed voltage while pressing and rolling the pair of welding rollers against the contact portion of the package and the lid. . Moreover, the process of temporarily attaching a lid to a package by spot welding or the like may be provided before seam welding.

  In recent years, as electronic components have become increasingly smaller, packages and lids have become extremely small in size, so that the lid on the package is likely to be displaced only by receiving a slight external force. If tacking or seam welding is performed in a state where the position of the lid is deviated, sealing failure is likely to occur, and the product yield will be reduced. For this reason, a method has been proposed in which the lid is fixed at a predetermined position on the package by attracting the lid with a magnet (see, for example, Patent Document 1 or 2).

Japanese Patent No. 3194544 Japanese Patent No. 3416919

However, in the method described in Patent Document 1 or 2, since a disk-shaped magnet having a radial direction in the magnetization direction (direction connecting the N pole and the S pole) is used, the attractive force is reduced to a low level. There was a problem that the magnetism was large. That is, not only a large loss due to a line of magnetic force generated from the non-magnetic pole surfaces (N pole surfaces and S-pole surface) is large, the first place arranged to suck the lid (cap) by a line of magnetic force generated from the other predominantly pole faces Therefore, there is a problem that the attractive force is small and the magnetic force is easily lost.

  Further, since the thickness in the direction toward the package and the lid is thin, there is a problem that it is easily affected by heat at the time of spot welding or seam welding, and demagnetization due to heat is likely to occur. In addition, since the magnetization direction is the radial direction, it is difficult to determine which direction in the magnet is the magnetization direction, and the magnet orientation is not determined because it is necessary to be accommodated in the recess of the circular cross section. There is also a problem that it is extremely difficult to properly arrange the magnets.

  In view of such circumstances, the present invention is intended to provide a component fixing jig and a fixing device, and a fixed conveyance carrier capable of stably and easily fixing various components.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1A is a plan view of a component fixing jig 1 according to an embodiment of the present invention, and FIG. 1B is a bottom view of the component fixing jig 1. 2A is a cross-sectional view taken along line AA in FIG. 1A, and FIG. 2B is an enlarged view of a portion B in FIG. 2A. The component fixing jig 1 according to the present embodiment (hereinafter simply referred to as a fixing jig 1) is placed on various trays or transport carriers by being arranged below the various trays or transport carriers. This is for fixing (positioning) the component 100.

As shown in these drawings, the fixing jig 1 includes a substantially flat holding member 10 and magnets 20 that are permanent magnets arranged in a matrix on the holding member 10. In this embodiment, the component 100 includes a ceramic package 100a in which an electronic component such as a piezoelectric vibrator is housed, and a Kovar product placed on the package 100a so as to cover the opening of the package 100a. The lid 100b is temporarily attached to the package 100a by spot welding. Specifically, the fixing jig 1 specifically fixes and positions the lid 100b by pressing the lid 100b on the package 100a by attracting the lid 100b, which is a ferromagnetic material, by the magnetic force of the magnet 20. It is positioned and fixed by pressing on a tray or a transport carrier.

  The holding member 10 is formed in a substantially rectangular flat plate shape, and a plurality of receiving recesses 11 are formed on the upper surface 10a side. The housing recess 11 is for housing the magnet 20 inside and holding it in a predetermined position, and in the present embodiment, the housing recess 11 is a substantially rectangular parallelepiped recess that matches the shape of the magnet 20. An access hole 12 having a substantially circular cross section is provided at the bottom of the housing recess 11. The access hole 12 is for accessing the inside of the housing recess 11 from the bottom surface 10b side, and is for facilitating the attachment and removal of the magnet 20 in the housing recess 11.

  In the vicinity of both ends in the longitudinal direction of the holding member 10, a positioning hole 13 for positioning the fixing jig 1 and an insertion hole 14 through which a bolt or the like for fixing the holding member 10 to a frame or the like is inserted are provided. . The small holes 15 provided in the vicinity of both ends in the width direction of the holding member 10 are used for positioning when the holding member 10 is assembled.

  As shown in FIG. 2B, the holding member 10 is configured by laminating a plurality of plates. Specifically, a plurality of thin plates 10d formed with through-holes 16 constituting the housing recesses 11 are stacked on the base plate 10c formed with the access holes 12, and these are joined by spot welding to hold them. The member 10 is configured. In the present embodiment, the base plate 10c and the thin plate 10d are made of SUS304, which is a nonmagnetic material.

As shown in FIG. 1A, 32 housing recesses 11 are arranged in a line along the longitudinal direction of the holding member 10, and 16 rows of housing recesses 11 are provided in the width direction. . In other words, the accommodating recesses 11 are arranged in a 32 × 16 matrix in the holding member 10. In the present embodiment, since in the insertion hole 14 interfering with four positions has a housing recess 11 so as to omit the two, in fact 32 × 16- 8 = 50 4 pieces of the accommodation recess 11 is held The member 10 is provided.

Among these accommodating recesses 11, 28 × 16 = 448 on the inner side excluding two at both ends in the longitudinal direction of the holding member 10 are suction accommodating recesses 11 a arranged corresponding to the positions of the parts 100. It has become. That is, the fixing jig 1 of the present embodiment has 448 parts 100 (lid 100b) arranged in a matrix of 28 28 pieces in the first arrangement direction D1 and 16 pieces in the second arrangement direction D2. ) Are individually attracted and fixed by the magnetic force of the magnet 20. Moreover, both longitudinal ends of the 4 × 16- 8 = 56 pieces of the accommodation recess 11 of the holding member 10 disposes the magnet 20 for adjusting the state of magnetic field lines that are generated around the fixture 1 (magnetic field) For this purpose, it is an accommodation recess 11b for adjustment.

The magnet 20 is housed in the housing recess 11 as described above, and is thus disposed at a predetermined position. Accordingly, the 448 magnets 20 accommodated in the suction accommodating recess 11 a are arranged at positions corresponding to the component 100 and serve as the suction magnet 21 for actually attracting the component 100. The 56 magnets 20 accommodated in the adjustment accommodating recess 11b are adjustment magnets 22 for adjusting the state of the lines of magnetic force.

  As shown in FIG. 2B, all the magnets 20 are arranged with the N poles directed to one side in the longitudinal direction of the holding member 10 (in the present embodiment, the right side of the drawing). In other words, all the magnets 20 are arranged with the N poles directed to one side of the first arrangement direction D1. Of these magnets 20, the attracting magnet 21 is disposed so as to be positioned directly below each component within the arrangement range M of the components 100. Further, the adjustment magnet 22 is disposed at an appropriate position outside the arrangement range M of the components 100.

  FIGS. 3A and 3B are perspective views showing the appearance of the magnet 20. In the present embodiment, as shown in FIG. 3A, the magnet 20 is configured in a substantially cubic shape. That is, the dimension (full length) L1 in the first arrangement direction D1, the dimension (full length) L2 in the second arrangement direction D2 of the component 100, and the dimension (full length) L3 in the vertical direction D3 are made substantially equal. ing. By making the shape of the magnet 20 in this way, the component 100 can be reliably and stably fixed and demagnetization can be reduced. More specifically, the dimension L1 of the first arrangement direction D1, which is the direction connecting the N pole face 20a and the S pole face 20b of the magnet 20 (the direction connecting the N pole and the S pole, that is, the magnetization direction) is made as short as possible. At the same time, by making the dimension L3 in the vertical direction D3, which is the direction connecting the magnet 20 side and the component 100 side, as long as possible, the lines of magnetic force generated by the plurality of magnets 20 are made to be in an appropriate state. It is possible to achieve both effective holding (fixing) and reduction of demagnetization.

  FIG. 4A is a schematic diagram showing a state of magnetic lines of force generated by a conventionally used magnet 23, and FIG. 4B shows a state of magnetic lines of force generated by the magnet 20 of the present embodiment. FIG. In addition, the description of the magnetic force line shown with the broken line in these figures is not necessarily exact. As shown in FIG. 4 (a), the magnet 23 conventionally used for fixing the component 100 has a shorter vertical dimension D3 (thinner) and a longer first dimension D1. It was general. However, when the magnet 23 is configured in this way, there is a problem that demagnetization due to this increases because the lines of magnetic force generated from areas other than the N pole face 23a and the S pole face 23b, that is, free magnetic poles, increase. .

  Further, in the conventional magnet 23, since the distance between the magnets 23 is narrowed by increasing the dimension in the first arrangement direction D1, many lines of magnetic force connecting the N pole surface 23a and the S pole surface 23b facing each other are generated. At the same time, the plurality of magnets 23 arranged in the first arrangement direction D1 are easy to behave as one elongated magnet. That is, the lines of magnetic force generated from the N-pole surface 23a and the S-pole surface 23b are wasted without being effectively used for attracting the component 100, and the component 100 is caused by the lines of magnetic force generated from other than the N-pole surface 23a and the S-pole surface 23b. Since it attracts | sucks, there existed a problem that not only the attraction | suction force became weak but demagnetization became large further.

  On the other hand, as shown in FIG. 4B, according to the magnet 20 of the present embodiment, the dimension L1 in the first arrangement direction D1 is made relatively short and the dimension L3 in the vertical direction D3 is made relatively long. Therefore, it is possible to increase the lines of magnetic force generated from the N pole face 20a and the S pole face 20b, which are magnetic pole faces, and to reduce the lines of magnetic force generated from other than the magnetic pole face. That is, the number of free magnetic poles can be reduced, and the component 100 can be attracted mainly by the magnetic lines of force generated from the N-pole surface 20a and the S-pole surface 20b.

  Further, according to the magnet 20 of the present embodiment, even when the components 100 are arranged at the same pitch as the conventional one, the interval between the magnets 20 can be increased, so that the N pole face 20a and the S pole face 20b that face each other. It is possible to reduce the lines of magnetic force that connect the two, and make it difficult for the plurality of magnets 20 arranged in the first arrangement direction D1 to behave as one elongated magnet. That is, it is possible to reduce the interference between the magnets 20 adjacent to each other, and to attract the component 100 by effectively utilizing the lines of magnetic force generated from the N pole face 20a and the S pole face 20b of each magnet 20. .

  Further, although not shown in the drawings, the magnet 20 of the present embodiment has a component 100 (package 100a) that has a relatively short dimension L1 in the first arrangement direction D1 and a relatively long dimension L3 in the vertical direction D3. And the lid 100b) are not easily affected by heat. That is, by reducing the dimension L1 in the first arrangement direction D1, the heat receiving area of the heat transmitted from the component 100 side is reduced, and by increasing the dimension L3 in the vertical direction D3, heat is not easily transmitted to the entire magnet 20. Thus, demagnetization due to heat is less likely to occur.

  As described above, the magnet 20 of the present embodiment is not only small in aged demagnetization but also less likely to be demagnetized due to heat as compared with the conventional magnet 23, and each magnet 20 has an attractive strength with an appropriate strength. Can be generated. That is, the magnet 20 has an optimum shape for attracting and fixing the plurality of components 100 arranged along the first arrangement direction D1 by the plurality of magnets 20.

  Returning to FIG. 3A, in the magnet 20 of the present embodiment, the dimension L1 in the first arrangement direction D1, the dimension L2 in the second arrangement direction D2 of the component 100, the dimension L3 in the vertical direction D3, However, it is needless to say that the dimensions of the magnet 20 are not limited to this. In other words, if the dimension L1 is equal to or smaller than the dimension L3, that is, the same as the dimension L3 or shorter than the dimension L3, the above-described effects can be reliably obtained. Further, even when the dimension L1 is longer than the dimension L3, the above-described effects can be sufficiently achieved if the dimension L1 is 110% or less of the dimension L3.

  It should be noted that specific numerical values and ratios of the dimensions L1 and L3 may be appropriately set according to the size and shape of the component 100, the arrangement pitch of the component 100, the degree of magnetization of the magnet 20, the required attractive force, and the like. Further, the specific value of the dimension L2 or the ratio of the dimension L2 to the dimensions L1 and L3 is not particularly limited, and may be appropriately set according to the dimension and shape of the component 100. From the viewpoint of reducing the heat receiving area, the dimension L2 is preferably not more than the dimension L1.

  Further, the magnet 20 preferably has a size equal to or smaller than the size of the component 100 in order to attract the component 100 reliably and stably. Accordingly, when the component 100 is a minute electronic component such as a surface mount type piezoelectric vibrator, the dimensions L1, L2, and L3 are preferably 5 mm or less, and at least the dimension L1 is 2 mm or less. More preferable. In the present embodiment, the dimensions L1, L2, and L3 of the magnet 20 are each set to 2 mm.

Needless to say, the shape of the magnet 20 is not limited to a substantially cubic or rectangular parallelepiped, and other appropriate shapes can be adopted. For example, the magnet 20, as shown in FIG. 3 (b), may be one that is configured in a cylindrical shape, although not shown, be one that is configured in a cylindrical shape or a polygonal column shape such as Also good. When configuring the magnet 20 in a columnar or cylindrical shape or the like, as shown in FIG. 3 (b), it is preferable that the magnetization direction as the axis C direction. By doing in this way, since magnetization and anisotropy can be made easy, it becomes possible to obtain required magnetic force, without enlarging the magnet 20. FIG. Further, since the N pole face 20a and the S pole face 20b, which are magnetic pole faces, can be made substantially planar, the number of free magnetic poles can be reduced and the magnetic lines generated from the N pole face 20a and the S pole face 20b can be effectively utilized. The component 100 can be sucked. In addition, it is easy to determine the magnetization direction of the magnet 20, and it is easy to fix and arrange the magnet 20 by determining the direction of the magnetization direction.

  In addition, the material (type) of the magnet 20 is not particularly limited, and an appropriate magnet according to a necessary attraction force or use environment, such as a ferrite magnet, a neodymium magnet, a Samakova magnet, or an Alnico magnet, can be adopted. Needless to say.

  FIGS. 5A and 5B are schematic diagrams showing the operation of the adjusting magnet 22. As described above, in the present embodiment, the adjustment magnet 22 is arranged outside the arrangement range M of the components 100 at a position not corresponding to the components 100, thereby adjusting the state of the lines of magnetic force acting on the components 100. Yes. As a result, the component 100 can be held more reliably and stably.

  FIG. 5A shows an example in which the adjusting magnet 22 is not arranged. As described above, in the present embodiment, the magnet 20 is configured so that the lines of magnetic force generated from the N pole face 20a and the S pole face 20b are increased. For this reason, when only the attracting magnet 21 arranged corresponding to each component 100 is used without arranging the adjusting magnet 22, for example, at the S pole side end (the other side end) in the first arrangement direction D <b> 1. As shown in FIG. 5A, the lid 100b attracted by the attracting magnet 21 is attracted more strongly toward the S pole surface 20b where magnetic lines of force from a distance are concentrated. Similarly, although not shown, the lid 100b attracted by the attracting magnet 21 at the N pole side end (one side end) in the first arrangement direction D1 is on the N pole surface 20a where the magnetic lines of force going away are concentrated. It will be drawn more strongly towards.

  Then, for example, when the entire component 100 is minute and lightweight, the components 100 arranged at both ends of the arrangement range M change their postures along the lines of magnetic force, and as a result, FIG. As shown in Fig. 1, there was a case that the situation was upright. Further, when the temporary attachment of the lid 100b is not sufficient, the lid 100b may be detached from the package 100a.

  In this embodiment, in order to avoid such a phenomenon, the adjusting magnet 22 is arranged. That is, by arranging the magnets 20 beyond the arrangement range M of the parts 100 on both sides in the first arrangement direction D1, as shown in FIG. 5B, the end of the magnetic field lines that pass far away are concentrated. The S pole face 20b (N pole face 20a) is moved away from the component 100, and the state of the magnetic lines of force acting on the component 100 at the end of the arrangement range M is set to be equivalent to the magnetic field lines acting on the component 100 inside. I have to.

  Thereby, it is possible to stably fix all the parts 100 arranged in the arrangement range M. That is, as shown in FIG. 5B, since the magnetic force of the corresponding attracting magnet 21 can appropriately press all the lids 100b toward the package 100a, the position of the lid 100b with respect to the package 100a. It is possible to fix the entire part 100 as well as to prevent misalignment.

  In the present embodiment, the suction magnet 21 and the adjustment magnet 22 are constituted by substantially the same magnet 20, and the distance between the suction magnets 21 (that is, the arrangement pitch of the components 100) P1 and the suction magnet 21 Although the distance P2 between the magnet 21 and the adjustment magnet 22 is substantially the same, the present invention is not limited to this. That is, for example, the state of the lines of magnetic force is adjusted by changing the strength or dimension of the adjusting magnet 22 from that of the attracting magnet 21 or changing the distance P2 between the attracting magnet 21 and the adjusting magnet 22. It may be. In the present embodiment, two adjustment magnets 22 are arranged on both sides of the first arrangement direction D1 in principle, but the number of adjustment magnets 22 can be changed or the adjustment magnets 22 can be changed. The state of the lines of magnetic force may be adjusted by changing the distance P3 between them.

  Further, instead of the adjusting magnet 22, a ferromagnetic material such as iron, cobalt, or nickel may be disposed. In this case, the same effect as that obtained when the adjusting magnet 22 is disposed can be obtained. . In the present embodiment, as described above, the adjustment magnet 22 is omitted in the portion that interferes with the insertion hole 14 of the holding member 10, but the bolt or the like that is inserted into the insertion hole 14 is made of a ferromagnetic material. Therefore, it is possible to adjust the state of the lines of magnetic force in the same manner as in the row in which the adjusting magnet 22 is not omitted.

  FIG. 6 is a schematic view showing another operation of the adjusting magnet 22. In the present embodiment, since the dimension L1 of the magnet 20 in the first arrangement direction D1, that is, the dimension in the magnetization direction is shortened as much as possible, the magnet 20 originally has a demagnetizing field (in the left direction in the figure) generated in itself. It is susceptible to the influence of broken arrows).

  However, in the present embodiment, since the plurality of magnets 20 are arranged along the magnetization direction, a positive magnetic field generated between the adjacent magnets 20 (on the right-pointing broken line in the drawing) Arrow) acts, and the influence of the demagnetizing field can be reduced. In particular, in the present embodiment, by providing the adjusting magnet 22, it is possible to cause a positive magnetic field to act on all the attracting magnets 21, and thus a problem caused by a demagnetizing field generated in the attracting magnets 21. Can be reduced.

  FIGS. 7A and 7B are schematic views showing other arrangement examples of the magnet 20, and are plan views. In the above example, the magnetization direction of the magnet 20 (the direction connecting the N pole and the S pole) is made to substantially coincide (substantially parallel) with the first arrangement direction D1, but this is shown in FIG. As described above, the magnet 20 may be arranged in a posture in which the magnetization direction is in a direction having an angle with respect to the first arrangement direction D1 in a plane orthogonal to the vertical direction D3.

  By doing so, for example, the diagonal direction of the rectangular component 100 and the magnetization direction of the magnet 20 are substantially matched (substantially parallel), that is, the magnetization direction is substantially matched with the direction in which the total length of the component 100 is the longest. Therefore, the component 100 may be able to be fixed more reliably and stably. Thus, the magnet 20 does not necessarily have to be arranged in a posture in which the magnetization direction substantially coincides with the first arrangement direction D1, and the magnetization direction is directed in an appropriate direction according to the shape, arrangement, etc. of the component 100. Can be placed in a (shifted) position.

  In this case as well, it goes without saying that each magnet 20 is in a state in which the N pole is directed to one side of the first arrangement direction D1. For example, as shown in FIG. 7B, if an appropriate oblique direction corresponding to the shape and arrangement of the components 100 is defined as a first arrangement direction D1, the magnetization direction of the magnet 20 and the first arrangement are arranged. It is also possible to consider that the direction D1 is substantially the same.

  Even in such a case, by making the magnet 20 have the above-described shape, the component 100 can be reliably and stably fixed and demagnetization can be reduced. In this case, the dimension L1 of the magnet 20 is the dimension in the magnetization direction, but not the dimension in the first arrangement direction D1. Further, by appropriately arranging the adjustment magnets 22, it is possible to stably fix all the components 100 arranged in the arrangement range M and reduce the influence of the demagnetizing field.

  When the magnets 20 are arranged in this way, as shown in FIG. 7A, the adjusting magnets 22 are provided on both sides of the second arrangement direction D2 in addition to both sides of the first arrangement direction D1. It may be arranged. That is, also in this case, the arrangement of the adjustment magnets 22 is not particularly limited, and an arbitrary number can be arranged at an arbitrary position according to the state of the lines of magnetic force. Although not shown, the attracting magnet 21 and the adjusting magnet 22 may be arranged in postures having different magnetization directions, or arranged by changing the posture so that the magnetization directions are different for each position. You may make it do.

  Next, the component fixing device 2 will be described.

  FIGS. 8A to 8C are schematic views showing a component fixing device 2 according to an embodiment of the present invention. In these drawings, each part of the component fixing device 2 is simplified. The component fixing device 2 according to the present embodiment (hereinafter simply referred to as a fixing device 2) supports a carrier carrier 200 that conveys the component 100, and also supports the component 100 (lid 100b) placed on the carrier carrier 200. It is fixed (positioned).

  As shown in FIG. 8A, the fixing device 2 supports the fixing jig 1, the attachment member 30 to which the fixing jig 1 is attached, the moving mechanism 40 that raises and lowers the attachment member 30, and the transport carrier 200. And a supporting member 50. In addition, the fixing device 2 is connected to a carry-in device 60 for carrying the carry carrier 200 and a carry-out device 70 for carrying the carry carrier 200.

The attachment member 30 is disposed below the support surface 50 a where the support member 50 supports the transport carrier 200. The fixing jig 1 is fixed to the mounting member 30 by a bolt or the like (not shown) inserted through the insertion hole 14. Further, a positioning pin 32 protrudes upward from the upper surface of the mounting member 30, and the fixing jig 1 is positioned by inserting the positioning pin into the positioning hole 13. Yes.

  The moving mechanism 40 is configured to move the mounting member 30 up and down by a known structure such as an air cylinder or a ball screw transmission mechanism. Accordingly, the fixing jig 1 moves together with the attachment member 30 so as to approach and separate from the transport carrier 200 placed on the support surface 50 a of the support member 50.

  The support member 50 supports the end portion of the transport carrier 200 from below by the support surface 50a. That is, an opening (not shown) through which the fixing jig 1 can pass is formed in the support surface 50a, and the fixing jig 1 raised by the moving mechanism 40 comes into contact with the lower surface of the transport carrier 200. ing. Further, as the fixing jig 1 is raised, the positioning pin 32 is inserted into the positioning hole 202 provided in the conveying carrier 200, so that the conveying carrier 200 is positioned with respect to the fixing jig 1. ing.

  The structures of the carry-in device 60 and the carry-out device 70 are not particularly limited, and may be, for example, a belt conveyor or a robot arm. Moreover, it cannot be overemphasized that the carrying-in direction and carrying-out direction of the conveyance carrier 200 are not limited to a specific direction.

  FIGS. 8B and 8C show the operation of the fixing device 2. As shown in FIG. 8B, the fixing device 2 is in a standby state in which the fixing jig 1 is lowered. And after the conveyance carrier 200 which mounted the component 100 by the carrying-in apparatus 60 is carried in, as shown in FIG.8 (c), the fixing jig 1 is raised. At this time, the conveyance carrier 200 is positioned with respect to the fixing jig 1 by inserting the positioning pins 32 into the positioning holes 202 of the conveyance carrier 200.

  As a result, the attracting magnet 21 provided in the fixing jig 1 is disposed at a position where the lid 100b can be attracted, whereby the lid 100b is pressed against the package 100a as shown in FIG. 8A. The component 100 is fixed. Thereafter, although not shown, a predetermined process such as seam welding of the lid 100b is performed. After the predetermined process is completed, the fixing jig 1 is lowered to release the fixing of the component 100, the positioning pin 32 is extracted from the positioning hole 202 of the transport carrier 200, and the transport carrier 200 is unloaded by the unloading device 70. .

The moving mechanism 40 may be capable of moving the positioning pin 32 up and down independently of the attachment member 30.

In addition, the magnetization direction of the magnet 20 can be easily determined, and the orientation of the magnet 20 can be easily determined and arranged by, for example, the shape of the housing recess 11, so that manufacturing costs and maintenance costs can be reduced. .

  Moreover, the magnet 20 is arranged over the range longer than the components 100 along the arrangement direction. By doing so, the magnetic field lines acting on the component 100 can be adjusted to an appropriate state, and the influence of the demagnetizing field can be reduced, so that the component 100 can be fixed reliably and stably.

  The magnet 20 includes a suction magnet 21 disposed at a position corresponding to each component 100 and an adjustment magnet 22 disposed at a position not corresponding to the component 100 outside the arrangement range M of the components 100. It is out. By doing so, the magnetic lines of force acting on the component 100 are adjusted to an appropriate state, the influence of the demagnetizing field is reduced, and the plurality of components 100 are reliably and stably fixed by the corresponding suction magnets 21 respectively. be able to.
