Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram illustrating a first detection apparatus according to an exemplary embodiment. The device is suitable for detecting the height and the size of the cavity structure in different scenes. In the present disclosure, only whether the height of the battery cover in the three-stage mobile phone case of a common smart phone in a living scene meets the control size is described. As shown in fig. 1, the mobile phone housing 1 includes an aluminum part 11 and a plastic part 12, and a predetermined portion 13 of the plastic part 12 needs to control the height dimension. The detection device 2 comprises at least one first stop 21 (only 1 shown in fig. 1), at least one second stop 23 (only 1 shown in fig. 1) and a reference panel 22. At least one first stop 21 and at least one second stop 23 are provided on the reference panel 22;

the first stop 21 and the second stop 23 can translate back and forth along the plane of the reference panel 22;

the height difference between the first stop block 21 and the second stop block 23 is determined according to the error variation range of the preset part of the object to be detected.

In this embodiment, at least one first stopper 21 may be disposed on a first surface of the reference panel 22, and at least one second stopper 23 may be disposed on a second surface of the reference panel 22; or at least one first stopper 21 may be provided on the second surface of the reference panel 22 and at least one second stopper 23 may be provided on the first surface of the reference panel 22; alternatively, the first stopper 21 and the second stopper 23 are provided at the first surface (or the second surface) at the same time. The first surface and the second surface are located opposite to each other. For example, in fig. 1, the first stopper 21 is provided on a first surface of the reference plate 22, i.e., an upper surface thereof, and the second stopper 23 is provided on a second surface of the reference plate 22, i.e., a lower surface thereof. When the reference panel 22 is rotated horizontally (i.e., the upper surface and the lower surface of the reference panel 22 are reversed in fig. 1), the first surface is the lower surface of the reference panel 22, and the second surface is the upper surface of the reference panel 22. For the sake of clarity, the present embodiment will be described by directly using the positions of the components in the drawings.

In this embodiment, it is assumed that the reference panel 22 is produced by a device with high precision, and the flatness of the first surface and the second surface of the reference panel 22 is very small, and the error change from the preset position can be ignored. The two side edges of the mobile phone case 1 can bear the reference panel 22, and the second surface, i.e. the lower surface of the reference panel 22 is parallel to the upper surface of the predetermined portion 13. Thus, the plane where the end face of the first stopper 21 or the second stopper 23 is located is parallel to the plane where the end face of the preset portion 13 is located, namely, the two end faces are not inclined, and therefore the detection precision is guaranteed.

In this embodiment, the height of the predetermined portion 13 is a desired height H '(the unit may be determined as needed) in the production process, and the actual height of the predetermined portion 13 may be changed to a certain extent due to the influence of the precision of the relevant production process, and may be lower or higher than the desired height H'. In practical application, because the cell-phone casing can assemble preset the position, do not break away from the cell-phone body under the normal use condition can. That is, the assembly process of the mobile phone housing allows a certain variation H of the height of the predetermined portion 13, i.e. the variation range of the actual height of the predetermined portion 13 is [ H '-H, H' + H ] (which may be called as a control height). If detect the height of predetermineeing the position, and when highly satisfying above-mentioned management and control altitude requirement of predetermineeing the position, it is qualified to explain the cell-phone casing.

In this embodiment, the heights of the first stopper 21 and the second stopper 23 are set according to the control height of the preset portion 13, where the height of the first stopper 21 (i.e., the distance between the end surface far from the fixed position and the upper surface of the reference panel 22) is H-H, and the height of the second stopper 23 (i.e., the distance between the end surface far from the fixed position and the lower surface of the reference panel 22) is H + H. The height H is a height corresponding to the actual height of the predetermined portion 13 being the desired height H'.

As shown in fig. 1, when the reference panel 22 is driven to translate along the plane thereof, the second stopper 23 is driven to translate toward the predetermined portion 13. For example, the second stopper 23 is driven to translate toward the preset portion 13 on the left side of the mobile phone case 1 in fig. 1, and if the second stopper 23 can pass through the preset portion 13, it means that the height of the preset portion 13 is too low. In the present embodiment, the pass means that the predetermined portion 13 and the second stopper 23 (or the first stopper 21) do not contact each other when they are staggered in position. If the second stopper 23 cannot pass through the predetermined portion 13, it indicates that the height of the predetermined portion 13 meets the lower limit requirement of the control height. Then, the second stopper 23 is driven to translate towards the preset portion 13 on the right side of the mobile phone shell 1 in fig. 1, and the judging process is repeated.

Then, the positions of the first stopper 21 and the second stopper 23 are reversed, and after the position reversal, the second stopper 23 is disposed at the position of the first stopper 21 shown in fig. 1, and the first stopper 21 is disposed at the position of the second stopper 23 shown in fig. 1.

When the reference panel 22 is driven by a driving force to translate along the plane, the first stopper 21 is driven to translate towards the predetermined portion 13. For example, the first stopper 21 is driven to translate to the preset position 13 on the left side of the mobile phone shell 1 in fig. 1, and if the first stopper 21 cannot pass through the preset position 13, it indicates that the height of the preset position 13 is too high, and the upper limit requirement of the control height is not met. If the first stopper 21 can pass through the predetermined portion 13, it indicates that the height of the predetermined portion 13 meets the upper limit requirement of the control height. Then, the first stopper 21 is driven to translate to the preset portion 13 on the right side of the mobile phone shell 1 in fig. 1, and the judging process is repeated.

According to the detection device provided by the embodiment of the disclosure, the first stopper 21 or the second stopper 23 can be translated to really preset whether the height of the portion 13 meets the requirement of the control height, so that the process of adjusting the height of the height gauge and reading data in the related art can be omitted. Along with the increase of the length of the preset part 13, namely, the number of detection points is increased, the more time is saved by the detection equipment disclosed by the invention, and the more obvious the detection efficiency is improved.

When the width of the mobile phone shell 1 or the cavity of the object to be detected is large, the translation amplitude of the reference panel 22 is large, so that the occupied space of the detection equipment is too large; and the length of the reference panel 22 is required to be greater than twice the width of the mobile phone housing 1 (or the cavity of the object to be detected), and the reference panel 22 needs a larger panel material. To this end, the exemplary embodiments of the present disclosure also provide a second detection apparatus. As shown in fig. 2, the detection apparatus provided by the embodiment of the present disclosure includes a

reference panel

22, 2

first stoppers

21, and 2 second stoppers 23. Wherein 2 first stoppers 21 are provided on the upper surface of the

reference panel

22 and 2 second stoppers 23 are provided on the lower surface of the reference panel 22. When the reference panel 22 is placed on both edges of the handset housing 1, the distance L between the second stopper 23 and the predetermined portion 13 will be smaller than the distance between the two in fig. 1, so that the reference panel 22 only needs to be translated left and right by L or slightly over L. With the increase of the object cavity to be detected, the higher the space utilization rate of the detection equipment disclosed by the invention is, the higher the material utilization rate of the panel is.

On the basis of the above embodiments, an exemplary embodiment of the present disclosure further provides a third detection device and a fourth detection device. The third detecting device shown in fig. 3 corresponds to the first detecting device shown in fig. 1, and the fourth detecting device shown in fig. 4 corresponds to the second detecting device shown in fig. 2, and for the same features, please refer to the description of the first and second detecting devices. The following third detection device is different from the first detection device and the fourth detection device is different from the second detection device in that at least one limiting block 24 is further included. As shown in fig. 3, stoppers 24 are provided on both sides of the first stopper 21 and the second stopper 23 corresponding to the translational direction. As shown in fig. 4, a stopper 24 is provided on one side of the first stopper 21 and the second stopper 23 corresponding to the translation direction. Each stopper 24 is kept a predetermined distance from the first stopper and the second stopper that it protects. For example, the preset distance may prevent the second stopper 23 from continuously translating when the first stopper 21 or the second stopper 23 cannot pass through the preset portion 13, prevent the first stopper 21 or the second stopper 23 from being deformed too much to affect the measurement accuracy, or prevent the first stopper 21 or the second stopper 23 from continuously translating when the first stopper 21 or the second stopper 23 passes through the preset portion 13.

The above-described embodiment of the present disclosure describes a case where the first stopper and the second stopper are respectively disposed on the first surface and the second surface of the reference panel, that is, the first stopper 21 is fixed on the first surface of the reference panel 22, the second stopper 23 is fixed on the second surface of the reference panel 22, and then the driving force is applied to the reference panel 22 to make each stopper perform translational detection, resulting in that the width of the reference panel 22 is much larger than that of the mobile phone case 1, and the upper and lower surfaces of the reference panel 22 may be worn by multiple use to affect the detection accuracy. To this end, an exemplary embodiment of the present disclosure also provides a fifth detection apparatus, as shown in fig. 5, 6, and 7, including: a first stopper 21, a second stopper 23, a reference panel 22, and a slide block 25. The first stopper 21 and the second stopper 23 are fixed on the upper surface or the lower surface of the slide block 25, respectively (for details, see the arrangement of the first stopper 21 and the second stopper 23 in the first and second detection devices). A through hole 26 is provided in the middle of the reference panel 22, and the width of the through hole 26 matches the width of the sliding block 25, so that the sliding block 25 can move back and forth in the through hole 26 along the length direction thereof.

FIG. 6 is a top view of the detecting apparatus shown in FIG. 5, and FIG. 7 is a cross-sectional view of the detecting apparatus shown in FIG. 6 in the A-A' direction. Referring to fig. 5, 6 and 7, the left side and the right side of the sliding block 25 are respectively provided with a protrusion 27, and the reference panel 22 is provided with a slot matching with the protrusion 27, so that at the contact position of the sliding block 25 and the reference panel 22, referring to fig. 7, the protrusion 27 is engaged with the slot, and the purpose of fixing the sliding block 25 is achieved. As shown in fig. 6, when the reference panel 22 is placed on the mobile phone case 1, the slide block 25 is driven to translate left and right.

In practical applications, the length of the through hole 26 in this embodiment can be set according to the length of the sliding block, the reaching position of the first stopper or the second stopper. For example, when the size limiting block 21 cannot pass through the preset portion 13 on the left side of fig. 5, the left side of the sliding block 25 just contacts with the left side of the through hole 26, so that the sliding block 25 and the through hole 26 realize a limiting function and protect the first stop block and the second stop block from deformation. In addition, the datum plate 22 does not need to translate, reducing the likelihood of wear; and the length of the reference panel 22 is only slightly larger than that of the through hole, so that the occupied space of the detection equipment and the used panel material are reduced.

Of course, the through hole 26 may be set to be "L", "T" or "i" shaped, and the sliding block 25 translates along the length direction of the sliding block in the through hole 26, and then translates perpendicular to the length direction of the sliding block, which may be suitable for the detection situation when the preset position 13 is long.

The above-described embodiments of the present disclosure have described the case where the first stopper and the second stopper are respectively provided on the first surface and the second surface of the reference panel, and an exemplary embodiment of the present disclosure also provides a sixth detection apparatus. As shown in fig. 8, the detecting apparatus includes a first stopper 21, a reference plate 22, and a second stopper 23. The reference panel 22 is provided with a groove 28 corresponding to the first stopper 21 and the second stopper 23. As shown in fig. 9, the first stopper 21 and the second stopper 23 are coupled with their corresponding recesses 28 by a rotating member 29.

In normal state, the rotating member 29 is closed, and the first stopper 21 and the second stopper 23 are respectively located in the corresponding grooves 28; in operation, the rotating member 29 is opened, and the first stopper 21 or the second stopper 23 is perpendicular to the surface on which the reference panel is placed. Then, a driving force is applied to the reference panel 22, and the subsequent detection process refers to the working process of the first or other detection devices.

It can be seen that the device in this embodiment only needs to take out the first stopper 21 or the second stopper 23 from the recess 28, respectively, and thus the positions of the first stopper 21 and the second stopper 23 in fig. 1 need not be changed.

It can be understood that fig. 8 and 9 only describe the case that the first stopper 21 and the second stopper 23 are disposed on the same surface of the reference panel 22, and they may also be disposed on different surfaces according to actual needs.

An exemplary embodiment of the present disclosure also provides a seventh detecting device, as shown in fig. 10, which further includes a second driving means 3, compared to the first, second, third, fourth, and sixth detecting devices. The driving device 3 includes a bracket 31, a driving motor 32, and a coupling clip 33. The connecting clamp 33 fixes one end of the reference panel 22, and then the driving motor 32 drives the connecting clamp 33 to drive the reference panel 22 to move horizontally to the predetermined portion 13 according to a predetermined direction (e.g. left or right in fig. 10), and the subsequent detection process refers to the working process of the first or other detection devices.

An exemplary embodiment of the present disclosure also provides an eighth detecting apparatus, as shown in fig. 11, which further includes a first driving device that replaces the connecting clip 33 in the second driving device 3 with a gear 34, compared with the seventh detecting apparatus. A gear 34 is fixed on the drive shaft of the drive motor 32. In this case, the reference panel 22 is provided with a rack 29' matching the gear 34. As shown in the sectional view in the direction B-B 'in fig. 11, the gear 34 is engaged with the rack 29' and, when the driving motor 32 is operated, the reference panel 11 is translated to the left or right in fig. 11. The subsequent detection process refers to the working process of the first or other detection devices.

An exemplary embodiment of the present disclosure further provides a ninth detecting device, as compared with the eighth detecting device shown in fig. 12, the driving means 3 may include both the connecting clip 33 and the gear 34, so that the connecting clip 33 may fix the slide block 25, the first stopper 21 or the second stopper 23, the rack 29 ' is provided on the bracket 31, and the gear 34 is engaged with the rack 29 ' as shown in a cross-sectional view in the C-C ' direction. Thus drive motor 32 operates to move slider 25 to the left or right of FIG. 12. The subsequent detection process refers to the working process of the first or other detection devices.

An exemplary embodiment of the present disclosure also provides a tenth detection apparatus, as shown in fig. 13, which further includes a third driving device 4, as compared with the first, second, third, fourth, and fifth detection apparatuses. The driving device 4 includes a bracket (not shown in the drawings, and refer to the bracket 31 shown in fig. 10), a driving motor 41, and a connecting clip 42. The connecting clamp 43 fixes one end of the reference panel 22, and then the driving motor 41 drives the connecting clamp 42 to rotate the reference panel 22 180 degrees around the driving shaft of the driving motor 41, i.e. the positions of the first stopper 21 and the second stopper 23 are exchanged. During the adjustment of the position of the reference panel 22 by the third driving means 4, the attachment clip 33 needs to be temporarily distanced from the reference panel. The subsequent detection process refers to the working process of the first or other detection devices.

An exemplary embodiment of the present disclosure also provides an eleventh detection apparatus, as shown in fig. 14, which further includes a pressure detection unit 5, compared with the detection apparatuses provided in the above embodiments. Referring to a cross-sectional view in a direction D-D' in fig. 14, the pressure detecting unit 5 includes a plurality of strain gauges, and the strain gauges are disposed in the first stopper 21 and the second stopper 23 in a one-to-one correspondence. When the first stopper 21 or the second stopper 23 cannot pass through the predetermined portion 13, that is, the first stopper 21 or the second stopper 23 is deformed, the strain gauge is linearly changed and sends the change amount to a processing circuit (not shown) of the pressure detecting unit 5, and the processing circuit calculates the stress of the strain gauge and compares the stress with the predetermined pressure. When the stress is larger than the preset pressure, it indicates that the first stopper 21 or the second stopper 23 cannot pass through the preset portion 13, and at this time, the processing circuit generates a prompt message indicating that the height of the preset portion 13 is too low or too high. The processing circuit can also directly display the stress and the preset pressure for the use of detection personnel. The subsequent detection process refers to the working process of the first or other detection devices.

The preset pressure can be set according to the driving force borne by the detection equipment, and can also be set according to the stress characteristic of the stop block material, and the application is not limited.

An exemplary embodiment of the present disclosure further provides a twelfth detection apparatus, which further includes a video detection unit, compared with the detection apparatuses provided in the above embodiments. As shown in fig. 14, the video capture circuit in the video detection unit is directly opposite to the preset portion 13, and the video capture circuit can capture the video within the area 6. When the first stopper 21 or the second stopper 23 enters the area 6, the video capturing circuit captures video within the area 6. Then, the processing circuit of the video detection unit processes the video to obtain the position relationship between the first stopper 21 or the second stopper 23 and the preset portion 13, and generates corresponding information or instructions according to the position relationship. For example, the video detection unit sends a control command to the first driving device or the second driving device, so that the second driving device drives the reference panel to translate back and forth along the plane of the second driving device, or the first driving device drives the sliding block 25 to translate back and forth along the length direction of the first driving device in the through hole 26. When the first stopper 21 passes through the position of the preset part 13, the video acquisition circuit acquires a video in the area 6, and the processing circuit processes the video to obtain the position relation between the first stopper 21 and the preset part 13. When the first stop 21 cannot pass the position of the preset portion 13, the processing circuit generates a prompt (alarm or display) indicating that the height of the preset portion 13 is too high. When the first stopper 21 passes through the position of the preset portion 13, the processing circuit generates a control command to be sent to the third driving device continuously, the third driving device is controlled to drive the reference panel to rotate 180 degrees, then the second driving device drives the reference panel to translate back and forth along the plane where the second driving device is located, or the first driving device drives the sliding block 25 to translate back and forth along the length direction of the first driving device in the through hole 26. When the second stopper 23 passes through the position of the preset portion 13, the video acquisition circuit acquires a video in the area 6, and the processing circuit processes the video to obtain the position relation between the second stopper 23 and the preset portion 13. When the second stopper 23 can pass through the position of the preset part 13, the processing circuit generates a prompt message (alarm or display) indicating that the height of the preset part 13 is too low; when the second stopper 23 cannot pass through the position of the preset portion 13, the processing circuit generates a prompt message indicating that the height of the preset portion 13 meets the control requirement.

As shown in fig. 15, the method is implemented based on the detection device provided in each of the above embodiments, where a reference panel of the detection device is placed at an edge of an object to be detected, and it is ensured that a first stopper or a second stopper of the detection device is arranged opposite to a preset portion of the object to be detected, and the method includes:
