Hereinafter, an embodiment of a positioning device according to the present invention will be described with reference to FIGS. 1 to 6. This positioning device is a device for positioning on a support surface a device configured such that a lead protrudes from a side surface of a mold part (main body). The device is positioned and inspected, or the device is used for taping. Used to change the direction.
First, a device that is positioned by the positioning apparatus will be described.
As shown in FIG. 1 and FIG. 2, the device D is an SOP (Small Outline Package), and is formed from a substantially rectangular parallelepiped mold part D1 and side surfaces D11 and D12 arranged at positions opposite to the mold part D1. Each has a protruding lead D2.
The bottom surface D13 of the mold part D1 is formed in a rectangular shape and serves as a reference surface for positioning. From the bottom surface D13, the above-described side surfaces D11 and D12 are erected, and second side surfaces D14 and D15 adjacent to the side surfaces D11 and D12 are erected. In this example, three leads D2 are arranged on the side surface D11, and two leads D2 are arranged on the side surface D12 in a direction parallel to the bottom surface D13 with a space therebetween.

Next, the positioning device of this embodiment will be described.
The positioning device 1 includes a support base 10 whose upper surface is a support surface 11, a contact member 21, a second contact member 22, a third contact member 23, which are detachably mounted on the support surface 11. A first clamping member 24 and a second clamping member 25 are provided.
The support 10, the contact members 21, 22, 23 and the clamping members 24, 25 are made of a metal such as steel, for example, and a coating such as DLC (Diamond Like Carbon) is applied to the surface thereof. It is preferable.

The support surface 11 is formed flat and can contact the bottom surface D13 of the device D.
As shown in FIG. 1 and FIG. 3, the contact member 21 is formed with a first contact surface 21 a that is erected from the support surface 11 and set parallel to the X direction parallel to the support surface 11. Yes. The second contact member 22 is provided with a second contact surface 22a that is erected from the support surface 11 and is set on the same surface as the first contact surface 21a. The third abutting member 23 is formed with a third abutting surface 23 a that is erected from the support surface 11 and is set parallel to the first abutting surface 21 a. In the present embodiment, the contact surfaces 21a, 22a, and 23a are set to be orthogonal to the Y direction that is parallel to the support surface 11 and orthogonal to the X direction. Further, the direction in which the contact surfaces 21 a, 22 a, and 23 a are erected is the Z direction that is orthogonal to the X direction and the Y direction, respectively, and is a direction parallel to the normal line of the support surface 11.

The contact surfaces 21a, 22a, and 23a formed in this way are such that the distance between the first contact surface 21a and the third contact surface 23a in the Y direction is the distance between the side surface D11 and the side surface D12 in the device D. It is set almost equal. For this reason, when the device D is disposed between the contact surfaces 21a and 22a and the third contact surface 23a, the contact surfaces 21a and 22a contact the side surface D11 and the third contact surface 23a. Abuts against the side surface D12.
As shown in FIG. 3, in the present embodiment, the height H1 in the Z direction of the first contact surface 21a, the second contact surface 22a, and the third contact surface 23a is set as the side surface of the device. It is set lower than the height H2 at which D11 and D12 stand.

When viewed in the Z direction as shown in FIG. 1 with the bottom surface D13 of the device D in contact with the support surface 11, the lead D2 of the device D has a contact member 21 and a second contact member 22. And it arrange | positions in the position which does not overlap with the 3rd contact member 23, respectively. That is, in the X direction, the distance L1 between the contact member 21 and the second contact member 22 is set larger than the width of the lead D2, and the distance L2 between the adjacent leads D2 arranged on the side surface D11 is the contact member. 21 and the width of the second contact member 22 are set larger.
Further, when viewed in the Z direction, the third contact member 23 has a normal C3 at the center of the third contact surface 23a and a normal C1 at the center of the first contact surface 21a. It arrange | positions so that it may be located between the normal lines C2 in the center part of the 2nd contact surface 22a.

  As shown in FIGS. 2 and 3, the protruding tip 21 b (the portion farthest from the support surface 11) of the contact member 21 becomes narrower as the distance from the support surface 11 increases in the X direction and the Y direction. It is formed to become. Similarly, the protruding tip portion 22b of the contact member 22 and the protruding tip portion 23b of the contact member 23 shown in FIG. 1 have a width that decreases as the distance from the support surface 11 increases in the X direction and the Y direction. Is formed.

As shown in FIGS. 1 and 2, the first clamping member 24 is formed with a first clamping surface (clamping surface) 24 a that stands from the support surface 11 and is set to be orthogonal to the X direction. ing. The second clamping member 25 is provided with a second clamping surface (clamping surface) 25a which is erected from the support surface 11 and set in parallel to the first clamping surface 24a.
In the first clamping member 24 and the second clamping member 25, the first clamping surface 24a and the second clamping surface 25a face each other, and the X between the first clamping surface 24a and the second clamping surface 25a. The distance in the direction is set to be approximately equal to the distance between the second side surfaces D14 and D15 in the device D. For this reason, when the device D is disposed between the first clamping surface 24a and the second clamping surface 25a, the first clamping surface 24a abuts on the second side surface D14, and the second clamping surface 25a contacts the second side face D15.
The height H3 in the Z direction of the clamping surfaces 24a and 25a shown in FIG. 2 is set higher than the height H1 in the Z direction of the contact surfaces 21a, 22a and 23a (see FIG. 3).

  Next, the positioning method of this embodiment for positioning the device D on the positioning apparatus 1 configured as described above will be described. This positioning method includes a positioning process between the clamping surfaces 24a and 25a for positioning the device D in the X direction, and a contact surface for positioning the device D in the Y direction between the contact surfaces 21a, 22a and 23a. An interposition positioning step, and a support step of bringing the bottom surface D13 of the device D into contact with the support surface 11.

First, in the sandwiching surface positioning step, the device D is brought closer to the support surface 11 from the Z direction in a state where the top surface of the mold part D1 is adsorbed by a handler (not shown) or the like. Since the height H3 of the clamping surfaces 24a, 25a is set higher than the height H1 of the contact surfaces 21a, 22a, 23a, the device D has the clamping surfaces 24a, 22a, 23a before the contact surfaces 21a, 22a, 23a. Abuts 25a. Then, as shown in FIG. 4, the first clamping surface 24a is brought into contact with the second side surface D14 of the device D and the second clamping surface 25a is brought into contact with the second side surface D15 of the device D. The device D is positioned in the X direction with respect to the support surface 11.
At this time, since the projecting tip 21b is formed on the contact member 21, even if the mold part D1 or the lead D2 of the device D contacts the projecting tip 21b from the Z direction, the mold part D1. Alternatively, the lead D2 moves in the X direction or the Y direction along the slope formed on the protruding tip 21b. This prevents the mold part D1 or the lead D2 from being locked to the contact member 21 and prevents the bottom surface D13 of the device D from being able to contact the support surface 11 of the support base 10.

Next, in the contact surface positioning step, as shown in FIG. 5, the device D is brought closer to the support surface 11, the contact surfaces 21a and 22a are brought into contact with the side surface D11, and the third contact surface 23a. Is brought into contact with the side surface D12. The device D that has been positioned in the X direction with respect to the support surface 11 in the sandwiching surface positioning step is further positioned in the Y direction with respect to the support surface 11.
Subsequently, in the support step, the device D is positioned in the Z direction with respect to the support surface 11 by bringing the bottom surface D13 into contact with the support surface 11 as shown in FIG.
Through the above steps, the device D is positioned with respect to the support surface 11 in all directions of the X direction, the Y direction, and the Z direction.

As described above, according to the positioning device 1 and the positioning method of the present embodiment, the lead D2 of the device D does not overlap the contact members 21, 22, and 23 when viewed in parallel with the Z direction. Therefore, when the device D is attached to the support surface 11 from the Z direction, the lead D2 of the device D is prevented from interfering with the contact members 21, 22, and 23.
Since the contact surfaces 21a and 22a contact the side surface D11 of the device D and the third contact surface 23a contact the side surface D12, the device D can be positioned in the Y direction.
Further, when viewed in the Z direction, the third contact member 23 has a normal C3 at the center of the third contact surface 23a and a normal C1 at the center of the first contact surface 21a. It arrange | positions so that it may be located between the normal lines C2 in the center part of the 2nd contact surface 22a. For this reason, the rotation of the device D is restricted in any direction around the Z direction.
Therefore, by restricting movement of the device D in the Y direction and rotation around the Z direction, the device D is placed on the support surface 11 in the Y direction while preventing the contact members 21, 22, and 23 from contacting the lead D2. Can be positioned.

The device D has second side surfaces D14 and D15, and the clamping members 24 and 25 include clamping surfaces 24a and 25a. For this reason, the device D can be positioned on the support surface 11 from the X direction.
Since the height H3 of the clamping surfaces 24a, 25a is set higher than the height H1 of the contact surfaces 21a, 22a, 23a, when the device D is attached to the support surface 11, the device D is first positioned in the X direction. Then, it is positioned in the Y direction. This can prevent the lead D2 from interfering with the contact members 21, 22, 23 in the X direction when the device D contacts the contact surfaces 21a, 22a, 23a.
Since the height H1 of the contact surfaces 21a, 22a, 23a is set lower than the height H2 of the side surfaces D11, D12 of the device, it protrudes from the contact surfaces 21a, 22a, 23a in the mold part D1 in the Z direction. The device D positioned on the support surface 11 can be easily detached from the support surface 11 by gripping the part.

The protruding tip 21b of the abutting member 21 is formed such that the width in the X direction and the Y direction decreases as the distance from the support surface 11 in the Z direction increases. For this reason, even when the mold part D1 and the lead D2 of the device D are in contact with the contact member 21 in the Z direction, the mold part D1 or the lead D2 is X along the slope formed on the protruding tip part 21b. Therefore, the mold part D1 and the lead D2 can be made difficult to be locked to the contact member 21 in the Z direction.
Further, since the contact members 21, 22, 23, and the clamping members 24, 25 are detachably mounted on the support surface 11, the contact members according to the size of the device and the position and number of leads arranged in the mold portion. The device can be positioned on the support surface 11 by appropriately selecting the clamping member.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The change of the structure of the range which does not deviate from the summary of this invention, etc. are included.
For example, in the above-described embodiment, when there is no need to position the device D in the X direction with respect to the support surface 11 such as when the gap in the X direction between the lead D2 and the contact members 21 and 22 is large, the positioning device May not include the clamping members 24 and 25.

  In the embodiment, it is assumed that all the heights of the contact surfaces 21a, 22a, and 23a are set lower than the height H2 of the side surfaces D11 and D12 of the device D. However, the height of at least one of the contact surfaces 21a, 22a, and 23a only needs to be set lower than the height H2. In this case, the device D can be detached from the support surface 11. Furthermore, when using a handler or the like that adsorbs to the top surface of the mold part D1 when the device D is removed from the support surface 11, all the heights of the contact surfaces 21a, 22a, and 23a are equal to the side surfaces D11 and D12 of the device. It may be set higher than the height H2.

Moreover, in the said embodiment, the protrusion front-end | tip part 21b of the contact member 21 was formed so that a width | variety might become narrow, respectively, as it spaced apart from the support surface 11 in a X direction and a Y direction. However, when the device D can be sufficiently positioned in the X direction with respect to the support surface 11 by the sandwiching members 24 and 25, the protruding tip portion 21b may be formed to have the same width in the X direction.
In the embodiment, when the bottom surface D13 of the device D is in contact with the support surface 11, when viewed in the Z direction as shown in FIG. 1, the contact member 21 is located between the leads D2 adjacent in the X direction. , 22 and 23 are arranged. However, the position where the contact member is arranged is not limited to this. For example, as shown at a position P in FIG. 1, the contact member may be arranged outside the lead D2 adjacent in the X direction.

  In the embodiment, in the device D, the lead D2 may be disposed on only one of the side surfaces D11 and D12. Further, the surface mounting type of the device positioned by the positioning device is not limited to SOP. For example, as shown in FIG. 6, the leads D2 are arranged on all of the side surfaces D11 and D12 and the second side surfaces D14 and D15. A surface mount device D21 such as QFP (Quad Flat Package) can also be used.
