Description

  This case relates to a test apparatus and a test method.

  A manufacturer who manufactures a device needs to guarantee the robustness of the device to an end user or the like. For example, a manufacturer that manufactures a device (for example, a mobile phone) in which the second housing slides with respect to the first housing needs to test and guarantee the robustness of the slide structure (slide mechanism) of the device. . Conventionally, in the robustness guarantee, a method has been employed in which a person repeatedly slides a device and counts the number of slide operations until the slide structure (mechanism) is damaged or failed.

  In addition, in order to automate the tests for guaranteeing robustness, recently, a test device (referred to as a conventional device) has been developed that applies the same stress to human equipment as it slides and counts the number of slides with a counter. It's getting on.

  Patent Document 1 discloses an inspection apparatus that inspects a part having a click feeling such as a switch. The inspection apparatus of Patent Document 1 determines whether or not a part is defective based on a difference between a displacement-load curve measured for the part and a reference curve.

  Hereinafter, an embodiment of a test apparatus and a test method will be described in detail with reference to FIGS. FIG. 1 is a perspective view of a mobile phone testing apparatus 100 according to an embodiment. The test apparatus 100 of FIG. 1 is an apparatus that performs a test (destructive test) on the robustness of a slide-type (slidable) mobile phone, and most of the test apparatus 100 is on a top plate 14 supported by a plurality of legs 12. Is provided. In the following description, the direction perpendicular to the top plate 14 is referred to as the Z-axis direction, and two directions perpendicular to the Z-axis direction are referred to as the X-axis direction and the Y-axis direction.

  The test apparatus 100 is an apparatus for simultaneously testing two mobile phones 50 as devices, and a pair of base portions 36 fixed on the top board 14 and a pair of terminals fixed on the top board 14 and extending in the Y-axis direction. Guides 22A and 22B, a pair of moving bodies 24A and 24B that move in the Y-axis direction along the guides 22A and 22B, a pair of support portions 26A and 26B provided on the moving body 24A, and a moving body 24B. A pair of support portions 26C and 26D provided above, a support plate 28 as a force applying mechanism supported by the support portions 26A to 26D, and two distance sensors 32 as position detection portions are provided.

  The base portion 36 is a base that holds (supports) the mobile phone 50. In the vicinity of each of the base portions 36, a plurality of positioning members 38 are provided. The positioning member 38 is a member for positioning and fixing the mobile phone 50 at an appropriate position on the base portion 36.

  Of the moving bodies 24A and 24B, a rack gear 20 extending in the Y-axis direction is provided on the −X side surface of one moving body 24A. The rack gear 20 is in a state in which the gear 18 is engaged. The gear 18 is fixed to the rotating shaft of the rotary motor 16 provided on the lower surface side of the top plate 14, and the rack gear 20 (and the moving body 24 </ b> A) is changed according to the rotation of the rotary motor 16 (and the gear 18). It moves in the Y-axis direction along the guide 22A. By this movement, a force in the Y-axis direction acts on the support plate 28 and the moving body 24B. That is, in the present embodiment, the support plate 28 slides in the + Y direction or the −Y direction according to the rotation direction of the rotary motor 16.

  FIG. 2 is an enlarged view of the support plate 28 taken out. As shown in FIG. 2, the support plate 28 includes a center plate 29a extending in the X-axis direction, and both end plates 29b and 29c extending in the Y-axis direction connected to ± X ends of the center plate 29a. The support plate 28 includes contact portions 31a, 31b, 31c, and 31d that are connected to the center plate 29a and have an L-shape when viewed from the X-axis direction.

  Pressure sensors 30 </ b> A and 30 </ b> B as force detection units are provided on the opposing surfaces of the contact units 31 a and 31 b. Pressure sensors 30A and 30B are also provided on the opposing surfaces of the contact portions 31c and 31d. In the following description, the pressure sensor 30A is referred to as “first pressure sensor 30A”, and the pressure sensor 30B is referred to as “second pressure sensor 30B”.

  In FIG. 3, the vicinity of the contact portions 31a and 31b of FIG. 1 is shown in a simplified manner. As shown in FIG. 3, the first pressure sensor 30 </ b> A and the second pressure sensor 30 </ b> B are arranged so as to sandwich the mobile phone 50 placed on the base portion 36. Here, the interval between the first and second pressure sensors 30 </ b> A and 30 </ b> B in the Y-axis direction is set to be larger than the total length of the mobile phone 50 in the Y-axis direction. That is, when one pressure sensor (30A or 30B) and the mobile phone 50 are in contact with each other, there is no contact between the other pressure sensor (30B or 30A) and the mobile phone 50.

  As shown in FIGS. 3 and 1, the distance sensor 32 is provided in the vicinity of the −Y side of the base portion 36 on the top plate 14 via a support hardware 34. The distance sensor 32 is, for example, a non-contact distance sensor using a laser, and is a distance from the surface on the −Y side of the contact portion 31a (or 31c) of the support plate 28, that is, the Y axis of the support plate 28. The direction position is measured.

  In the test apparatus 100 configured as described above, the support plate 28 reciprocates in the Y-axis direction, so that the same stress is applied to the mobile phone 50 as when a sliding mobile phone 50 is slid by a person. Can be done.

  FIG. 4 shows a control system of the test apparatus 100 in a block diagram. As shown in FIG. 4, the test apparatus 100 includes a control device 70 as a determination unit. The control device 70 controls the driving of the rotary motor 16 and causes the mobile phone 50 to deteriorate or fail based on the relationship between the detection values of the first pressure sensor 30A and the second pressure sensor 30B and the detection value of the distance sensor 32. It is determined whether or not an error has occurred. The determination method will be described in detail later.

  As shown in FIG. 3, the mobile phone 50 to be tested in the test apparatus 100 includes a first housing 51 and a second housing that is slidable along the Y-axis direction with respect to the first housing 51. 52. Between the first housing 51 and the second housing 52, a slide guide (not shown) for guiding the second housing 52 in the Y-axis direction with respect to the first housing 51 is provided. It is assumed that the first housing 51 is provided with an input interface such as a numeric keypad. It is assumed that the second casing 52 is provided with a liquid crystal monitor, a speaker, and the like.

  Between the first housing 51 and the second housing 52, as shown in FIGS. 5A and 5B, a spring mechanism 60 as an assist mechanism is provided. 5A and 5B, for convenience of illustration, the first casing 51 and the spring mechanism 60 are indicated by solid lines, and the second casing 52 is indicated by broken lines (FIG. 7A). The same applies to FIG. 7B).

  The spring mechanism 60 has two attachment portions 62a and 62b. Among these, one attachment portion 62 a is connected to the + Z surface of the first housing 51, and the other attachment portion 62 b is connected to the −Z surface of the second housing 52. FIG. 6A is an enlarged view of the spring mechanism 60 taken out. As shown in FIG. 6A, the spring mechanism 60 includes a central member 64, a pair of moving parts 66a and 66b that slide with respect to the central member 64, and the central member 64 and the moving parts 66a and 66b. Compression coil springs 68a and 68b.

  The center member 64 has a main body 72 and slide shafts 74a and 74b fixed to the main body 72, as shown in FIG. The moving parts 66a and 66b are slidably held on the slide shafts 74a and 74b of the center member 64, as shown in FIG. Among these, the attaching part 62a mentioned above is provided in the moving part 66a, and the attaching part 62b is provided in the moving part 66b. The compression coil springs 68a and 68b always apply an urging force (elastic force) Fe shown in FIG. 6A to the moving parts 66a and 66b.

  In the spring mechanism 60 configured as described above, as shown in FIG. 6 (c), a force (compression force) Ff against the biasing force Fe acts on the moving parts 66a and 66b, whereby the entire length (attachment) The distance between the parts 62a and 62b) is shortened. When the force Ff is no longer applied, the state returns to the state of FIG. 6A due to the urging force (elastic force) Fe.

  Next, the operation (movement) of the spring mechanism 60 configured as described above in the mobile phone 50 will be described with reference to FIGS. 5 (a), 5 (b), 7 (a), and 7 (b). Based on this description

  FIG. 5A shows a state where the second housing 52 is located at the end in the −Y direction. In the state of FIG. 5A, the spring mechanism 60 is in a state where the entire length is extended most (see FIG. 6A). From this state, as shown in FIG. 5B, when the force Fc acts on the second housing 52, the second housing 52 receives the force Fc and moves in the + Y direction. In this case, the spring mechanism 60 rotates around the attachment portion 62a and shortens the entire length thereof, so that the force Fg acts on the second casing 52 by the elastic force of the compression coil springs 68a and 68b. Therefore, in the state of FIG. 5B, when the user stops pressing the second housing 52 in the + Y direction (when the force Fc is not applied), the state automatically returns to the state of FIG. (Inhalation occurs).

  Further, when a force Fc is further applied to the second housing 52 from the state of FIG. 5B, the longitudinal direction of the spring mechanism 60 coincides with the X-axis direction as shown in FIG. 7A. It will be in the state. In this case, the spring mechanism 60 has the shortest overall length as shown in FIG. 6C, but in this state, the spring mechanism 60 only generates a force in the X-axis direction. The force in the Y-axis direction by the spring mechanism 60 does not act. On the other hand, in the state shown in FIG. 7A, if even a slight force Fc is applied to the second housing 52, the force in the + Y direction (the force Fh shown in FIG. 7B) is generated by the elastic force of the spring mechanism 60. ) Acts on the second housing 52. Thereby, even if a user does not apply force, the 2nd housing | casing 52 moves to the position shown in FIG.7 (b) automatically (suction arises).

  Note that if the spring mechanism 60 deteriorates or breaks down, the suction operation may not function, or conversely, the suction operation may occur earlier.

  Next, processing of the control device 70 in the test apparatus 100 will be described along the flowcharts of FIGS. 8 and 9 with reference to other drawings as appropriate. In the following description, a test of one mobile phone 50 will be described. However, in practice, since the test apparatus 100 tests a plurality of mobile phones 50 at the same time, a plurality of processes described below are performed simultaneously in parallel.

  As a premise of processing, it is assumed that a parameter n indicating the number of tests (slide times) is set (initialized) to 0. Further, as shown in FIG. 10A, the mobile phone 50 is in a closed state (a state in which the first housing 51 and the second housing 52 are overlapped), and the first and second pressure sensors 30A, 30A, It is assumed that none of 30B is in contact with the mobile phone 50.

  In the process of FIG. 8, first, in step S <b> 8, the control device 70 controls the rotary motor 16 to start the movement of the support plate 28 in the + Y direction. Here, the control device 70 determines the rotational speed of the rotary motor 16 so that the moving speed of the support plate 28 is slower than the suction speed of the second housing 52 by the spring mechanism 60.

  Next, in step S10, the control device 70 stands by until the first pressure sensor 30A detects contact. In this case, the control device 70 constantly monitors the detection value of the first pressure sensor 30A. And the control apparatus 70 transfers to step S12 in the stage (stage which became the state of FIG.10 (b)) when the detected value became larger than predetermined value (for example, 0).

  In step S12, the control device 70 determines whether or not the distance sensor 32 is a normal value. Here, the “normal value” is a value to be output from the distance sensor 32 when the first pressure sensor 30A contacts the second housing 52 in a state where the mobile phone 50 is positioned at a normal position. means. The mobile phone 50 is positioned by the positioning member 38 shown in FIG. 1 as described above. Therefore, when the mobile phone 50 is not accurately positioned by the positioning member 38, the distance sensor 32 does not output a normal value.

  If the determination in step S12 is affirmative, that is, if the mobile phone 50 is positioned at a normal position, the process proceeds to step S16. If the determination in step S12 is negative, step S14 is performed. Migrate to

  If transfering it to step S14, the control apparatus 70 will determine with an initial position error. Then, the control device 70 outputs an initial position error using a warning device (not shown) (for example, a display device or a speaker), and ends all the processes in FIGS.

  On the other hand, when the determination in step S12 is affirmed and the process proceeds to step S16, the control device 70 determines whether or not the detection value of the first pressure sensor 30A is equal to or greater than a predetermined value. The “predetermined value” in this case is detected by the first pressure sensor 30A before the force Fh of FIG. 7B is generated in the spring mechanism 60 in the mobile phone 50 (before the suction in the + Y direction occurs). It means the minimum value of power detection value. When the determination in step S16 is affirmative, that is, when the detection value of the first pressure sensor 30A is equal to or greater than a predetermined value, and the second casing 52 of the mobile phone 50 is in contact with the first pressure sensor 30A. The process proceeds to step S18.

  In step S18, the control device 70 determines whether or not the detection value of the distance sensor 32 is within a predetermined range A. The “predetermined range A” in this case means the range of the position (distance from the distance sensor 32) at which suction should occur when the spring mechanism 60 is in a normal state (when it is not deteriorated / failed). To do. It is assumed that the predetermined range A is measured in advance for each type of mobile phone and is held by the control device 70. If the determination here is negative, that is, through FIGS. 10C and 10D, the support plate 28 and the second housing 52 are located at positions where suction should occur. If it cannot be determined from the detection value of the first pressure sensor 30A that suction has occurred (in the case of FIG. 10F), the process proceeds to step S20.

  In step S20, the control device 70 determines that a suction error (deterioration / failure of the spring mechanism 60) has occurred. Then, the control device 70 outputs a suction error, and ends all the processes in FIGS. When a suction error is output, a parameter n value indicating the number of tests (slide times) is also output. On the other hand, if the determination in step S18 is negative, that is, if the second housing 52 has not yet reached the position where the suction should occur (FIG. 10E) (FIG. 10C or FIG. In the state d), the process returns to step S16.

  On the other hand, when the determination in step S16 is negative, that is, when the detection value of the first pressure sensor 30A is smaller than a predetermined value (when suction occurs as shown in FIG. 10E). The process proceeds to step S22. In step S22, the control device 70 determines whether or not the detection value of the distance sensor 32 is within a predetermined range A. The “predetermined range A” in this case is the same as the “predetermined range A” in step S20, and the position (distance from the distance sensor 32) where suction occurs when the spring mechanism 60 is in a normal state. It means the range to include. If the determination in step S22 is negative, in step S24, the control device 70 determines a suction error (deterioration / failure of the spring mechanism 60). Then, the control device 70 outputs a suction error, and ends all the processes in FIGS. When a suction error is output, a parameter n value indicating the number of tests (slide times) is also output.

  On the other hand, if the determination in step S22 is affirmative, it means that the suction operation has occurred normally (the spring mechanism 60 has not deteriorated or failed). In this case, the process proceeds to step S26, and the control device 70 determines whether or not the detection value of the distance sensor 32 indicates a position where the movement in the + Y direction should end. If the determination is negative, step S26 is repeated. On the other hand, if the determination in step S26 is affirmative, the process proceeds to step S108 in FIG. When the processing of FIG. 8 is completed as described above, the mobile phone 50 is in a state in which the second housing 52 is slid from the state of FIG. 10A to the state shown in FIG. .

Next, the process of FIG. 9 will be described.
The process of FIG. 9 is basically the same as the process of FIG. 8 (in FIG. 9, the step number “S1XX” is assigned to the step corresponding to the process of FIG. 8 (step “SXX”)). Attached). In the process of FIG. 9, as shown in FIGS. 11A to 11E, after the support plate 28 starts moving in the −Y direction (after step S <b> 108), the control device 70 performs the second pressure The detection value of the sensor 30B and the detection value of the distance sensor 32 are monitored. Then, the control device 70 determines whether an initial position error or a suction error has occurred based on the detection value. In this case, as shown in FIG. 11A, step S110 is affirmed when the second pressure sensor 30B comes into contact with the second housing 52, and the detected value of the distance sensor 32 at that time is not a normal value. (S112: No), the control device 70 outputs an initial position error (step S114). On the other hand, when the detection value of the second pressure sensor 30B is equal to or greater than the predetermined value but the detection value of the distance sensor 32 is within the predetermined range B, the control device 70 outputs the suction error and the value of n (S120). (S116: affirmative, S118: affirmative)). In this case, the “predetermined range B” is a range of a position (distance from the distance sensor 32) where suction should occur when the spring mechanism 60 is in a normal state (when it is not deteriorated / failed). means.

  Further, the control device 70 is in a state where suction in the −Y direction should occur when the detection value of the second pressure sensor 30B becomes smaller than the predetermined value and the detection value of the distance sensor 32 is not within the predetermined range B. However, if it does not occur (in the case of FIG. 11 (f)), the suction error and the value of n are output (step S124 (S116: negative, S122: negative)). Note that while the determination in step S116 is positive and the determination in step S118 is negative, the support plate 28 slides the second housing 52 as shown in FIGS. 11 (b) to 11 (d). Keep doing.

  If the determination in step S126 is negative, the control device 70 repeats the determination in step S126. Thereafter, when the determination in step S126 is affirmed, the process proceeds to step S128.

  Thereafter, in step S128, the control device 70 increments n by 1 (n ← n + 1) and returns to step S8 in FIG. Thereafter, the control device 70 repeats the processes of FIGS. 8 and 9 until a suction error occurs.

  Here, FIG. 12A shows the relationship between the detection value (horizontal axis) of the distance sensor 32 and the detection value (vertical axis) of the first pressure sensor 30A when the support plate 28 is moved in the + Y direction. It is a graph which shows. In FIG. 12A, the solid line indicates the test result of the mobile phone before the deterioration / failure of the spring mechanism 60, and the alternate long and short dash line indicates the test result of the mobile phone after the deterioration / failure. As can be seen from this graph, when the spring mechanism 60 of the mobile phone 50 deteriorates or breaks down, suction occurs at a stage where the value (distance) detected by the distance sensor 32 is short, or the suction should occur. Inhalation may not occur.

  In the present embodiment, a change in the relationship between the detection value of the distance sensor 32 caused by such deterioration / failure and the detection values of the first and second pressure sensors 30A and 30B is detected by the processing of FIGS. doing. Thereby, in this embodiment, it becomes possible to perform degradation / failure determination of the spring mechanism 60 in real time without always creating a graph as shown in FIG.

  FIG. 12B is a graph corresponding to FIG. 12A when the support plate 28 is moved in the −Y direction. In the case of FIG. 12B as well, in the case of FIG. 12A, when the spring mechanism 60 deteriorates / fails, a graph as indicated by a one-dot chain line is obtained. However, in this embodiment, the change in the relationship between the detection value of the distance sensor 32 caused by such deterioration / failure and the detection value of the first and second pressure sensors 30A and 30B is changed to the processing shown in FIGS. By detecting by this, deterioration / failure determination of the spring mechanism 60 can be performed in real time.

  As described above in detail, according to the present embodiment, the control device 70 relates to the force applied to the second casing 52 by the support plate 28 detected by the first and second pressure sensors 30A and 30B. Based on the value (pressure in this embodiment) and the position of the support plate 28 in the sliding direction detected by the distance sensor 32, normality / abnormality of the spring mechanism 60 is determined (S18, S22, S118, S122). In this case, the contact relationship between the support plate 28 and the mobile phone 50 is detected by the first and second pressure sensors 30A and 30B, and the position of the support plate 28 is detected by the distance sensor 32. It can be appropriately determined whether or not the mechanism 60 is operating normally. That is, the deterioration / failure determination of the spring mechanism 60 can be performed appropriately. In the present embodiment, since deterioration / failure determination is performed based on the detection values of the first and second pressure sensors 30A and 30B and the distance sensor 32, a displacement-load curve is calculated as in Patent Document 1. Unlikely, the deterioration / failure of the spring mechanism 60 can be determined in almost real time.

  Moreover, in this embodiment, the control apparatus 70 determines whether it is an initial position error based on the detection result by the distance sensor 32 when the 1st, 2nd pressure sensor 30A, 30B detects a contact. Thereby, in this embodiment, the mounting state on the base part 36 of the mobile phone 50 can be confirmed using the detection values of the first and second pressure sensors 30A and 30B and the distance sensor 32.

  In the present embodiment, the moving speed of the support plate 28 is higher than the sliding speed (suction speed) of the second casing when the spring mechanism 60 assists the sliding of the second casing 52 (when suction occurs). Is set too late. As a result, when suction occurs, the support plate 28 and the second housing 52 do not come into contact with each other. Therefore, by using the presence or absence of this contact, it is possible to appropriately determine the deterioration / failure of the spring mechanism 60. .

  Further, in the present embodiment, even when different types of test objects (mobile phones) are tested, it is not necessary to make mechanical adjustments (such as component changes) of the test apparatus 100. That is, if the moving speed of the support plate 28 is changed according to the type of the mobile phone, the reference (normal value, predetermined value, predetermined range A, B, etc.) used in FIGS. 8 and 9 is changed. It is possible to deal with various mobile phones.

  In the above embodiment, the case where the control device 70 determines the initial position error and the suction error has been described. However, the present invention is not limited to this. For example, the control device 70 determines whether the device is normal or abnormal (waveform abnormality) based on whether or not the detection values by the first and second pressure sensors 30A and 30B are within a predetermined range. Also good.
