Embodiments of the present utility model provide an inspection jig.
Fig. 1 is a schematic view of an inspection jig according to an embodiment of the present utility model. Fig. 2 is another schematic view of the inspection jig shown in fig. 1, showing the inspection jig viewed from another angle.
As shown in fig. 1 and 2, the inspection jig 10 includes a base portion 11, a supporting portion 12, and a connecting portion 13, the supporting portion 12 supporting an electronic device as an inspection object, the connecting portion 13 connecting the base portion 11 and the supporting portion 12 and enabling the supporting portion 12 to rotate relative to the base portion 11.
In the embodiment of the application, the electronic device as the inspection object may be a printed circuit board with a plurality of mems microphones arranged thereon, but the application is not limited thereto, and the electronic device may be a single mems microphone, and in addition, the electronic device may be other devices to be inspected.
As is apparent from the above embodiments, the inspection jig enables the support portion to rotate relative to the base portion, and thus, when inspecting an electronic device, the support portion can be made to support the electronic device and rotate to a desired angle, and thus, it is possible to ensure that inspection angles of any electronic device are the same, and to ensure repeatability of inspection operations of the electronic device.
In one or more embodiments, the angle of rotation of the support portion relative to the base portion ranges from 0 to 90 degrees. The base portion is generally parallel to the horizontal direction, that is, the electronic device can be inspected at an angle within 0 to 90 degrees with respect to the horizontal direction, and the inspection operation requirement can be satisfied.
However, the present application is not limited thereto, and the rotation angle of the support portion with respect to the base portion may be more than 90 degrees, and may be set according to actual needs.
Fig. 1 and 2 show that the rotation angle a of the support portion 12 with respect to the base portion 11 is 90 degrees, but the present application is not limited thereto, and the rotation angle a may be 0 degrees or any angle within 0 degrees to 90 degrees.
In one or more embodiments, the connection portion can maintain the support portion at any angle in the range of 0 to 90 degrees relative to the base portion. That is, the connection portion not only enables the support portion to rotate relative to the base portion, but also, in the case of rotating to a desired angle, can maintain the rotation angle unchanged, which "maintaining" means that the support portion can maintain the rotation angle unchanged without receiving an external force, wherein the support portion is not included to support the electronic component, that is, the support portion can maintain the rotation angle unchanged with supporting the electronic component.
Therefore, the rotation angle of the supporting part relative to the base part can be maintained without additional components, and the inspection operation is convenient.
In the embodiment of the present application, as shown in fig. 1, the connection part 13 may include a first connection part 131 fixed to the base part 11 and a second connection part 132 fixed to the support part 12, and the first connection part 131 and the second connection part 132 are connected by a shaft 133 or the like.
In the embodiment of the present application, an existing structure may be used as the connection portion, for example, a hinge may be used as the connection portion, for example, a torque hinge, regarding which the related art is referred to, but the present application is not limited thereto, and other structures may be used as the connection portion as long as the support portion is allowed to rotate with respect to the base portion and the support portion is maintained at an arbitrary angle in the range of 0 to 90 degrees with respect to the base portion.
In the embodiment of the present application, the number of the connection parts is not limited, for example, fig. 1 and 2 show that the number of the connection parts 13 is two, but the present application is not limited thereto, and the number of the connection parts may be other values, for example, 1, 3, or more than 3.
In the embodiment of the present application, as shown in fig. 1 and 2, the connection portion 13 is provided at the edges of the base portion 11 and the support portion 12, and the plurality of connection portions 13 are arranged along the edges of the base portion 11 and the support portion 12.
In one or more embodiments, as shown in fig. 1 and 2, the inspection jig 10 further includes a boss 14, the boss 14 being provided on a side of the base portion 11 facing the support portion 12.
In the embodiment of the present application, in the case where the angle of the supporting portion with respect to the base portion is 0 degrees, that is, the supporting portion and the base portion are parallel to each other, the protruding portion 14 is in contact with the supporting portion. That is, the connecting portion and the boss portion 14 are the same in height between the base portion and the support portion. This ensures that the support portion and the base portion are reliably held at a position having a relative angle of 0 degrees.
In the embodiment of the present application, the shape of the boss 14 is not limited, for example, the boss 14 may be a rectangular parallelepiped, but the present application is not limited thereto.
In the embodiment of the present application, the number of the protruding portions 14 is not limited, for example, fig. 1 shows that the number of the protruding portions 14 is 2, but the present application is not limited thereto, and the number of the protruding portions 14 may be 1, 3 or more than 3, and may be set according to practical situations.
In the embodiment of the present application, the installation position of the boss 14 is not limited, for example, fig. 1 shows that the boss 14 is provided at a corner of the base portion 11 away from the edge where the connection portion is provided, but the present application is not limited thereto, and the boss 14 may be provided at other positions of the base portion 11.
In one or more embodiments, as shown in fig. 1, the base portion 11 is in a plate shape having a rectangular cross section, the connection portion 13 and the protrusion portion 14 are provided on one surface of the base portion 11, and 2 connection portions and 2 protrusion portions 14 are provided at four corners of the rectangular shape of the base portion 11, respectively, but the present application is not limited thereto.
Fig. 3 is a further schematic view of the inspection jig of the embodiment of the application, showing a case where the supporting portion is viewed from a direction perpendicular to the supporting portion, and fig. 4 is a further schematic view of the inspection jig of the embodiment of the application.
