Method and apparatus for testing cell phones
A phone holder for a mobile phone testing apparatus which comprises at least a base plate, a rest structure on the base plate for supporting a mobile phone, at least one block for contacting a mobile phone's narrow side, wherein the at least one block is moveably attached to the base plate, thereby enabling adapting the position of the block to a mobile phone being supported by said rest, and clamping means for releasable fixing the at least one first block in said position can be configured for securely holding almost any mobile phone model.
1. A phone holder for a mobile phone testing apparatus,
the phone holder comprising:
a base plate,
a rest structure on the base plate configured to support a mobile phone and thereby position the mobile phone parallel to the base plate,
at least one block movably attached to at least one of the base plate and rest structure, the at least one block configured to contact a mobile phone's narrow side and thereby define a mobile phone's position on said rest structure, and
clamping means for releasably fixing the at least one block relative to the at least one of the rest structure and base plate,
wherein
the rest structure comprises a layer of an elastic material with at least one suction cup having an opening facing away from the rest structure, the at least one suction cup configured to attach the mobile phone, positioned on the layer of an elastic material, to the rest structure by reducing pressure in the at least one suction cup.
2. The phone holder of claim 1 , wherein
the clamping means is configured to releasably fix the at least one block to the base plate by pressing said at least one block against the base plate or the rest structure, to thereby obtain a frictional locking of the at least one block relative to the base plate or the rest structure, respectively.
3. The phone holder of claim 1 , wherein
the rest structure comprises a spacer between the base plate and the layer of an elastic material.
4. The phone holder of claim 1 , wherein
the base plate has at least one opening configured to provide access to the base plate facing side when the mobile phone is supported by the rest structure.
5. The phone holder of claim 3 , wherein
the base plate has at least two openings between which there is at least one beam supporting the spacer.
6. The phone holder of claim 1 , wherein
at least one finger is moveably attached to the base plate, wherein said at least one finger is disposed to support at least one of a measurement device and an actuator and a plug holder.
7. The phone holder of claim 1 , wherein
the phone holder comprises at least one plug holder, the plug holder comprising:
a first fixed part affixed to at least one of the base plate and the rest structure, and
a second part freely moveable relative to the rest structure, the second part comprising means for attaching a plug connector, the plug connector configured to be inserted into a complementary socket of the mobile phone,
wherein the first part and the second part are connected by a bearing configured to enable a free movement of the second part relative to the rest structure.
8. A method for testing a mobile phone, comprising:
positioning a mobile phone's housing on a rest structure of a phone holder in a desired position,
adjusting at least one of position and orientation of at least one block to be in contact with a narrow side of the housing,
removing the housing from the rest structure,
positioning the mobile phone on the rest structure such that the narrow side of the mobile phone is in contact with the at least one block,
performing at least one function test of the mobile phone,
imaging the mobile phone with a camera, and determining at least one of the mobile phone's position and orientation on the rest structure,
based on said at least one of the position and orientation, determining a position of at least one of the mobile phone's controls,
driving a manipulator to actuate the at least one of said mobile phone's controls,
imaging at least one of a moveable part of a plug holder and a plug of the mobile phone with the camera,
determining an actual position of the at least one of the movable part of the plug holder and the plug based on results of said imaging,
driving the manipulator to push the movable part of the plug holder from the actual position to the desired position, and
inserting a stick of the manipulator into a coupling bore of the movable part of the plug holder, and subsequently pushing said movable part by moving the stick.
9. The method of claim 8 , wherein
at least one of the mobile phone's housing and the mobile phone is suctioned to the rest structure by generating a low pressure zone between the rest structure and the at least one of the mobile phone's housing and the mobile phone, to thereby fix a position of the at least one of mobile phone's housing and the mobile phone on the rest structure.
