Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of an embodiment of a detection apparatus for a wearable device provided in the present application, and fig. 2 is a schematic structural diagram of a rear side view of the wearable device in fig. 1. It should be noted that: the detection device is illustrated in fig. 1 in three directions X, Y and Z, mainly for convenience of description. Therefore, all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present application are mainly used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in fig. 1), and if the specific posture is changed, the directional indicator is changed accordingly. Further, if the front structure of the wearable device in fig. 1 is simply considered to be visible, it can be considered that fig. 2 illustrates the back structure of the wearable device.

As shown in fig. 1, the detecting device 10 may include a transmission assembly 11, a positioning assembly 12, a first detecting assembly 13 and a second detecting assembly 14. The transmission assembly 11 may be used to implement the transportation of the wearable device 100 between a loading/unloading zone (not shown in fig. 1) of the detection apparatus 10 to a certain test zone, and may also be used to implement the transportation of the wearable device 100 between a plurality of test zones of the detection apparatus 10. The transmission assembly 11 may include a fixed plate 111, a movable plate 112, and a first driving member 113, wherein the movable plate 112 is stacked on the fixed plate 111 and is capable of moving relative to the fixed plate 111 under the driving of the first driving member 113. Further, the positioning assembly 12 is disposed on the movable plate 112 and is used for carrying the wearable device 100. The first detecting component 13 is disposed on the fixing plate 111 and is used to cooperate with the second detecting component 14 to perform a first type of detection on the wearable device 100. The second detecting element 14 is disposed on the movable plate 112 and is used for performing a second type of detection on the wearable device 100. So set up, compare in artifical the detection, this application carries out multiple type detection to wearable equipment with the help of detection device to realize automatic, the integrated level is also high, and then reduces the cost of labor, increases detection efficiency.

Further, the detection device 10 may further include a reading assembly 15. As shown in fig. 1, the reading assembly 15 is disposed on a side of the movable plate 112 facing away from the fixed plate 111, and is used for reading an identification code (not shown in fig. 1) on the wearable device 100. For example: the reading assembly 15 is disposed opposite to the wearable device 100 in the Z direction. With this arrangement, before the detection device 10 detects the wearable device 100, the reading component 15 may acquire the identification code on the wearable device 100, so that the detection device 10 may be in communication connection with the wearable device 100 through a wireless communication technology, thereby facilitating acquisition of relevant test data. Wherein the reading component 15 may be an industrial camera and the identification code may be a bar code, a two-dimensional code, etc. For the wearable device 100, the identification code is uniquely determined better than its "identification card"; the detection data may also be uploaded to a Manufacturing Execution System (MES) of the equipment manufacturer, so as to facilitate quality control and problem tracing of the wearable device 100.

It should be noted that: the transmission assembly 11, the positioning assembly 12, the first detection assembly 13, the second detection assembly 14 and the reading assembly 15 shown in fig. 1 are two sets, so that the detection device 10 can detect two wearable devices 100 at the same time to further increase the detection efficiency.

As shown in fig. 2, the wearable device 100 may include a back shell 101, a bezel 102, a first electrode 103, a second electrode 104, a light sensing device 105, a power key 106, and a function key 107. Wherein the back shell 101 can be in contact with the skin of the user and the bezel 102 is connected to the back shell 101. Further, the first electrode 103, the second electrode 104, and the photo sensing device 105 may be disposed at corresponding positions on the back case 101, and may be partially exposed from the back case 101. The arrangement is such that when the wearable device 100 is worn by a user, the first electrode 103 and the second electrode 104 can be in contact with the skin of the user, so as to monitor vital signs such as electrocardio of the user; while the light sensing device 105 is capable of acting on the skin of the user in order to monitor vital signs such as the heart rate of the user. Of course, the wearable device 100 may also integrate other sensors to facilitate monitoring vital signs of the user, such as body temperature, blood glucose, blood pressure, etc. Further, the power key 106 and the function key 107 may be disposed at corresponding positions on the frame 102 to facilitate pressing operations by a user.

Based on the above detailed description, the first electrode 103 and the second electrode 104 may correspond to an electrocardiograph monitoring module of the wearable device 100, and the light sensing device 105 may correspond to a heart rate monitoring module of the wearable device 100. Obviously, the reliability of the ecg and the heart rate monitoring module directly affects the user experience of the wearable device 100. Further, the first electrode 103 and the second electrode 104 are partially exposed to the back case 101 because they are in contact with the skin of the user. Obviously, the impedance of the back case 101, the frame 102, and the power button 106 is also important to avoid the situation of leakage. Thus, the first type of detection may specifically be detection of a vital signs monitoring module of the wearable device 100, and the second type of detection may specifically be detection of electrical insulation of the wearable device 100.

As an example, the first type of detection may be detecting the reliability of at least one of the electrocardiograph monitoring module and the heart rate monitoring module of the wearable device 100, and the second type of detection may be detecting the impedance magnitude of at least one of the back shell 101, the bezel 102, and the power key 106 of the wearable device 100. Of course, if the wearable device 100 can also monitor vital signs of the user, such as body temperature, blood glucose, blood pressure, etc., the first type of detection can also be correspondingly detecting the reliability of at least one of the body temperature monitoring module, the blood glucose monitoring module, and the blood pressure monitoring module of the wearable device 100.

Further, since the back case 101 of the wearable device 100 mainly faces the Z direction and the frame 102 of the wearable device 100 mainly faces the X direction and the Y direction, the detection direction of the first detection component 13 acting on the wearable device 100 and the detection direction of the second detection component 14 acting on the wearable device 100 may not be the same. For example: the first detection assembly 13 moves along the Z direction; and the second detecting component 14 moves along the X direction or the Y direction, so that the first detecting component 13 and the second detecting component 14 cooperate to perform the first type of detection on the wearable device 100, and the second detecting component 14 performs the second type of detection on the wearable device 100. By the arrangement, the first detection component 13 and the second detection component 14 can perform multiple types of detection on the wearable device 100 from different directions in a mutually matched mode, so that the application range of the detection device 10 is expanded, and the detection efficiency of the detection device 10 is increased. Of course, in some other embodiments, the detection direction of the first detection component 13 acting on the wearable device 100 and the detection direction of the second detection component 14 acting on the wearable device 100 may be the same. For example: the first detection assembly 13 and the second detection assembly 14 both move along any direction of the X direction, the Y direction, and the Z direction to perform corresponding detection on the wearable device 100, but the orientation of the wearable device 100 needs to be adjusted according to the detection direction.

Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of the transmission assembly in fig. 1.

As shown in fig. 3, the transmission assembly 11 may further include an intermediate plate 114 and a second driver 115. The middle plate 114 is disposed between the movable plate 112 and the fixed plate 111 and can move relative to the fixed plate 111 under the driving of the second driving member 115, and the movable plate 112 can move relative to the middle plate 114 and further move relative to the fixed plate 111 under the driving of the first driving member 113. So configured, the fixing plate 111 can be used as a substrate to facilitate the arrangement of other structures of the detecting device 10. The middle plate 114 may be slidably connected to the fixing plate 111 by a sliding pair, so as to facilitate the transportation of the wearable device 100 between the loading/unloading zone and a certain test zone of the detection apparatus 10, and also facilitate the transportation of the wearable device 100 between a plurality of test zones of the detection apparatus 10. The movable plate 112 can be used as a supporting plate for disposing the related structures of the positioning assembly 12, the second detecting assembly 14, etc., and can be slidably connected to the middle plate 114 by means of a sliding pair for achieving precise positioning of the movable plate 112 and the structures thereon.

Further, the first driving member 113 and the second driving member 115 may be a cylinder, an electric cylinder, a servo motor, a stepping motor, and the like, which is not limited herein. Here, the driving direction of the first driving member 113 and the driving direction of the second driving member 115 may be the same, for example, both along the X direction. In addition, the first driving member 113 and the second driving member 115 may share one power source.

As an example, the fixed plate 111, the middle plate 114, and the movable plate 112 may be sequentially stacked in the Z direction, and a certain distance may be maintained between each two. In this way, four working areas can be divided in space, as shown in fig. 1 and 3, the positioning assembly 12, the second detecting assembly 14 and the reading assembly 15 can be disposed in the uppermost working area, and the first detecting assembly 13 can be disposed in the lowermost and/or penultimate working area. By the arrangement, the first detection component 13 and the second detection component 14 can detect the wearable device 100 from different directions, and structural interference between the two components does not occur, so that the reliability of the detection device 10 is increased.

Further, in order to facilitate the first detection assembly 13 and the second detection assembly 14 to cooperate to perform the first type detection on the wearable device 100, as shown in fig. 3, the middle plate 114 is provided with an avoidance groove 1141, and the movable plate 112 is provided with an avoidance hole 1121. The projection of the avoidance groove 1141 on the fixing plate 111 and the projection of the avoidance hole 1121 on the fixing plate 111 at least partially overlap, so that the first detection assembly 13 can contact with the wearable device 100 through the avoidance groove 1141 and the avoidance hole 1121.

It should be noted that: the avoiding groove 1141 is mainly used to avoid the intermediate plate 114 from structurally interfering with the first detecting unit 13 during the movement process, and therefore the dimension of the avoiding groove 1141 in the movement direction of the intermediate plate 114 should be no less than the working stroke of the intermediate plate 114.

Referring to fig. 4 and 5 together, fig. 4 is a schematic structural diagram of an embodiment of the positioning assembly in fig. 1, and fig. 5 is a schematic structural diagram of an embodiment of the carrier in fig. 4.

As shown in fig. 5, the carrier 121 may include a bottom 1211 and an annular periphery 1212. The bottom 1211 is provided with a first detection window 1213, and a projection of the first detection window 1213 on the movable plate 112 at least partially coincides with the avoidance hole 1121, so that the first detection assembly 13 can act on the wearable device 100 through the first detection window 1213. Annular periphery 1212 may be integrally connected to bottom 1211 at one end and open at the other end to facilitate access to wearable device 100. At this time, the space enclosed by the annular periphery 1212 and the bottom 1211 may be the same as or similar to the wearable device 100, that is, the carrier 121 may be a profiling fixture, so as to carry and position the wearable device 100. Further, the annular periphery 1212 is provided with a second detection window 1214 and a third detection window 1215, so that the second detection assembly 14 can act on the wearable device 100 through the second detection window 1214, and the identifier 122 can determine whether the wearable device 100 is carried on the carrier 121 through the third detection window 1215. The first detection window 1213 may be a through hole, the second detection window 1214 may be a through hole or a notch, and the third detection window 1215 may be a through hole or a notch.

Referring again to fig. 4, the identifier 122 may be an infrared proximity sensor capable of emitting and receiving infrared light through the third detection window 1215. The stopper 123 may have a pressing arm (not labeled) and can rotate relative to the movable plate 112 to press the wearable device 100 after it is placed on the carrier 121. For each bearing element 121, two limiting elements 123 may be disposed at intervals along a diagonal of the bearing element 121, so as to increase the reliability of the limiting elements 123.

Referring to fig. 6 and 7 together, fig. 6 is a schematic rear side view of the detecting device in fig. 1, and fig. 7 is a schematic structural view of an embodiment of the first detecting element in fig. 6. It should be noted that: because the first detection component can carry out the first type of detection to the wearable equipment along the Z direction, and can set up in the below of movable plate for its primary structure is all sheltered from by the movable plate, also is promptly invisible in fig. 1. Therefore, fig. 6 illustrates the relative position relationship between the first detecting device and the transmission assembly mainly from the rear side of the detecting device.

As shown in fig. 7, the first detecting assembly 13 may include a fixing base 131, a first telescopic member 132 and a first type probe 133. As shown in fig. 6 and 5, the first expansion member 132 may be an air cylinder, an electric cylinder, etc., and may be disposed on the fixing plate 111 by the fixing base 131, and the first type probe 133 may be disposed at an end of the first expansion member 132 close to the positioning assembly 12. The driving direction of the first telescopic member 132 may be along the Z direction, so that the first type probe 133 can pass through the movable plate 1121 through the avoiding hole 1121 under the action of the first telescopic member 132, and then can contact the wearable device 100 through the first detection window 1213.

Further, the first type probes 133 may be specifically classified into two groups. Wherein the first set of probes 1331 can be in electrical contact with the first electrode 103 on the back of the wearable device 100, and the second set of probes 1332 can be in electrical contact with the second electrode 104 on the back of the wearable device 100. In order to ensure that the probes are electrically contacted with the electrodes on the back of the wearable device 100, the first set of probes 1331 may be two probes electrically connected through the first serial piece 1333, and the second set of probes 1332 may be two probes electrically contacted through the second serial piece 1334. At this time, under the action of the first expansion piece 132, specifically, two probes of the first group of probes 1331 and two probes of the second group of probes 1332 may contact the wearable device 100 through the avoidance hole 1121 and the first detection window 1213; and the first and second

serial sheets

1333 and 1334 may not pass through the movable plate 112.

It should be noted that: the relative positions of the first electrode 103 and the second electrode 104 on the back shell 101 may be different for different models of wearable devices 100. Therefore, the relative positions of the first set of probes 1331 and the second set of probes 1332 in the first type of probe 133 can be adjusted so as to be in electrical contact with the first electrode 103 and the second electrode 104, respectively, thereby increasing the versatility of the first detecting element 13.

As shown in fig. 8, the second sensing assembly 14 may include a mounting plate 141, a second telescoping member 142, and a second type probe 143. The second telescopic member 142 may be disposed on the movable plate 112, and the second type probe 143 may be disposed on one end of the second telescopic member 142 close to the positioning assembly 12 through the mounting plate 141 and penetrate through the mounting plate 141. Further, the second telescopic member 142 may be an air cylinder, an electric cylinder, or the like, and the driving direction thereof may be along the X direction or the Y direction, so that the second type probe 143 can contact with the wearable device 100 via the second detection window 1214 under the action of the second telescopic member 142.

Further, the second type of probes 143 can include first probes 1431, second probes 1432, and third probes 1433. The first probe 1431 may be in electrical contact with the bezel 102 on the side of the wearable device 100, the second probe 1432 may be in electrical contact with the power button 106 on the side of the wearable device 100, and the third probe 1433 may be in electrical contact with the function button 107 on the side of the wearable device 100.

It should be noted that: the relative positions of the power key 106 and the function key 107 on the frame 102 may be different for different models of wearable devices 100. Therefore, the relative positions of the second probe 1432 and the third probe 1433 in the second type of probe 143 can be adjusted so as to be electrically contacted with the power key 106 and the function key 107, respectively, thereby increasing the versatility of the second detecting element 14.

Referring to fig. 9 and 10 together, fig. 9 is a schematic diagram illustrating a principle that the first detection component and the second detection component cooperate to perform a first type of detection on the wearable device according to the embodiment of the present application, and fig. 10 is a schematic diagram illustrating a principle that the second detection component performs a second type of detection on the wearable device according to the embodiment of the present application.

The ecg signal source 16 can simulate a standard ecg signal input of a normal human body, and the wearable device 100 collects the standard ecg signal, and performs an operation process through Fast Fourier Transform (FFT), thereby outputting a test result signal. Obviously, by comparing the difference between the test result signal and the standard ecg signal, the reliability of the ecg monitoring module of the wearable device 100 can be evaluated. In this process, the test content may specifically include an input dynamic range test, a gain accuracy test, a frequency response test, a system noise test, and the like, so as to evaluate the reliability of the electrocardiographic monitoring module of the wearable device 100 from multiple dimensions.

As shown in fig. 10, the first probe 1431 and the second probe 1432 may be electrically connected to the impedance tester 17 through an isolation type cable. After the first probe 1431 is electrically contacted with the frame 102 on the side of the wearable device 100 and the second probe 1432 is electrically contacted with the power button 106 on the side of the wearable device 100, the impedance tester 17 can detect the impedance between the power button 106 and the frame 102.

It should be noted that: the ecg signal source 16 and the impedance tester 17 can be integrated into the detecting device 10, for example, disposed below the fixing plate 111, so as to save the workshop area.

Based on the above detailed description, the first detecting component 13 and the second detecting component 14 can be synchronized during the detecting process. That is, when the first type of probe 133 of the first detecting element 13 is electrically contacted with the wearable device 100, the second type of probe 143 of the second detecting element 14 is also electrically contacted with the wearable device 100. So set up, not only make first detection component 13 can cooperate with second detection component 14 in order to carry out the first type of detection to wearable equipment 100, still make second detection component 14 carry out the second type of detection to wearable equipment 100 and can go on simultaneously with the aforesaid first type of detection, and then increase detection efficiency.
