It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] like Figures 1 to 3 As shown, an embodiment of the present application provides a detection device, which includes: a supporting component 1 and a holding component 2; the supporting component 1 has a first side wall 11 arranged in an arc shape to form a accommodating space, and the first side wall 11 is used to support the component to be detected 7; the holding component 2 has a target part 21, and the target part 21 is located in the accommodating space. The target part 21 can move relative to the first side wall 11, and is used to detect the component to be detected 7.

[0040] Specifically, the bearing assembly 1 can be a bearing seat, and an arc-shaped groove is provided on the bearing seat, and the groove wall of the arc-shaped groove serves as the first side wall 11 and constitutes an accommodating space. The bearing assembly 1 can also be a curved plate, and the inner concave surface of the curved plate serves as the first side wall 11 and constitutes an accommodating space. The specific structure of the bearing assembly 1 is not limited. The holding assembly 2 can be a combination of a mechanical arm and a target part 21. The target part 21 can be a roller or a slider with an arc-shaped transition surface, and is not specifically limited.

[0041] During the operation of the detection device provided by the present application, the component to be detected 7 is first arranged in the accommodating space. The component to be detected 7 can be a multi-layer structural component composed of FPC, so that the bending area of ​​the component to be detected 7 is in contact with the first side wall 11. The movement of the target part 21 relative to the first side wall 11 can be to make the target part 21 push against the component to be detected 7, or to provide a holding force to the component to be detected 7, and at the same time make the target part 21 move along the extension direction of the arc-shaped bend of the first side wall 11. Since the bending area of ​​the component to be detected 7 is in contact with the arc-shaped first side wall 11, the component to be detected 7 will be bent along the first side wall 11, resulting in different bending radii of each layer of the component to be detected 7, and then part of the component to be detected 7 will bulge in the direction away from the first side wall 11 to form a bulging structure 71. Such a setting makes the target part 21 push against and hold the component to be detected 7, and the gas in the internal gap of the component to be detected 7 where the target part 21 pushes against it flows to the part not pushed against, and the target part 21 moves along the extension direction of the arc-shaped bend of the first side wall 11, so that the target part 21 pushes against various parts of the component to be detected 7 and pushes the protruding structure 71 to move, and the gas in the internal gap of the component to be detected continues to flow, and the protruding structure 71 moves together with the target part 21, which proves that the layers of the component to be detected 7 are separated. If the protruding structure 71 no longer moves with the target part 21, or the protruding structure 71 disappears, it proves that the protruding structure 71 of the component to be detected does not move with the target part 21, or the protruding structure 71 disappears. It is in an unlayered state. At the same time, if there is partial adhesion between the layers of the component to be detected 7, the flowing gas can separate the adhesion by the push of the target part 21. Such a setting is simple to operate and has high efficiency, and it is not easy to miss the inspection.

[0042] like Figure 1 , Figure 2 As shown, in some embodiments, there is a target distance between the target part 21 and the first side wall 11 , and the target distance enables the target part 21 to abut against the component to be detected 7 .

[0043] Specifically, the target distance set between the target part 21 and the first side edge can be selected according to the thickness of the component 7 to be detected and the pressing force of the target part 21 on the component 7 to be detected. During the test, the target distance should be less than or equal to the thickness of the component 7 to be detected, so that the target part 21 can press the component 7 to be detected. The specific target distance can be selected according to the pressing force provided by the target part 21 for the component 7 to be detected. It is necessary to ensure that the provided pressing force will not cause damage to the component 7 to be detected. The pressing force can be controlled within the range of 1-3 Newtons. When the pressing force is 3 Newtons, the target distance is less than the thickness of the component 7 to be detected, and is closer to the first side wall 11 than when the pressing force is 1 Newton. Such a setting can effectively prevent damage to the component 7 to be detected while enabling the target part 21 to press the component 7 to be detected.

[0044] like Figure 1 , Figure 2 As shown, in some embodiments, the target part 21 has a roller structure that rotates relative to the first side wall 11 , or the target part 21 has a glue stick structure that slides relative to the first side wall 11 .

[0045] Specifically, the target part 21 can be a roller structure, and the roller structure presses the rolling surface of the component to be detected 7 against the component to be detected 7, and rolls it to realize the flow of gas in the gap of the component to be detected 7. The target part 21 can also be a rubber stick structure, and the rubber stick structure contacts the component to be detected 7, and while pressing the component to be detected 7, the contact area between the rubber stick structure and the component to be detected 7 is reduced, thereby preventing the component to be detected 7 from being damaged during the movement of the target part 21 due to the large contact area. In this embodiment, a roller structure can be selected, and a rubber material can be wrapped on the roller surface of the roller structure to prevent the roller structure from slipping during the rolling process, and at the same time, the component to be detected 7 is prevented from being damaged by the target part 21 by rolling.

[0046] like Figure 1 , Figure 2 As shown, in some embodiments, the pressing assembly 2 includes: a driving assembly 22, and the driving assembly 22 is connected to the target part 21 to make the target part 21 in a first motion state or a second motion state.

[0047] Specifically, the driving component 22 can be a combination of a rotating motor and a transmission component, or a multi-axis manipulator, which is not specifically limited. The connection method between the driving component 22 and the target part 21 can be realized by a mechanical clamp or a coupling component, which is not specifically limited. It can be selected according to the target part 21 and the transmission method of the target part 21. The first motion state can be that the target part 21 moves along the top of one side of the first side wall 11 to the first position on the other side of the first side wall 11, and the second motion state can be that the target part 21 moves along the top of the other side of the first side wall 11 to the second motion position on one side of the first side wall that is symmetrical to the first position relative to the first side wall 11, so that the target part 21 detects the component to be tested 7 with the same motion distance but different motion directions. The first motion state can also be moving from the top of one side of the first side wall 11 to the top of the other side, and the second motion state can also be moving from the first position to the second position, so that the target part 21 performs a secondary detection of the key parts while performing an overall detection of the component to be detected 7, and the first motion state and the second motion state are not specifically limited. The driving component 22 drives the target component 21 to be in the first motion state or the second motion state so that the detection device can perform more detailed detection on the component to be detected 7 to prevent the detection device from missing various parts of the component to be detected 7.

[0048] In the actual detection process, the target distance can be adaptively adjusted with the movement of the target part 21. For the position where the raised structure 71 is small and the stratification is not obvious, the target distance can be appropriately reduced to increase the holding force, so that the raised structure 71 is larger and the stratification phenomenon is more obvious. When the raised structure 71 is large enough, the target distance can also be increased to make the target distance equal to the thickness of the component to be detected 7 to reduce the wear of the target part 21 on the component to be detected 7. The adaptive adjustment of the specific target distance can be controlled according to the structure of the holding component, and the target distance can be adjusted by adjusting the movement path of the manipulator.

[0049] like Figures 1 to 3 As shown, in some embodiments, the first side wall 11 is a U-shaped groove structure; the first movement state is that the target part 21 moves from the top of one side of the groove structure along the first side wall 11 to the bottom of the groove structure; the second movement state is that the target part 21 moves from the top of the other side of the groove structure along the first side wall 11 to the bottom of the groove structure.

[0050] Specifically, the bearing component 1 can be a placement block with a U-shaped groove, and the groove wall of the U-shaped groove serves as the first side wall 11. The groove structure can make the component to be detected 7 better fit with the first side wall 11, and facilitate the target part 21 to roll the component to be detected 7. Since the bending area of ​​the component to be detected 7 has a boundary on the component to be detected 7, when the target part 21 is rolled to approach the boundary of the component to be detected 7, the raised structure 71 formed by rolling will stop moving with the target part 21, and the boundary of the bending area may be damaged due to the squeezing of the flowing gas. The first motion state and the second motion state are used to roll the component to be detected 7 so that the target part 21 moves from one side or the other side of the boundary of the bending area of ​​the component to be detected 7 along the first side wall 11 to the bottom of the groove, which effectively prevents the raised structure 71 from contacting the boundary of the dynamic bending area and preventing damage to the boundary.

[0051] During the setting process, two clamping surfaces can also be set. The two clamping surfaces are respectively connected to the extended boundaries at both ends of the groove structure and are tangent to the groove structure. Such a setting can clamp and limit the component 7 to be detected, preventing the component 7 to be detected from releasing the bending state due to its own internal stress, thereby separating the component 7 to be detected from the groove surface.

[0052] like Figure 1 , Figure 2As shown, in some embodiments, the driving component 22 also includes: a driving motor 221, a transmission shaft structure 222 and an elastic component 223; the driving motor 221 is arranged on one side of the supporting component 1; the transmission shaft structure 222 is connected to the driving end of the driving motor 221; one end of the two elastic components 223 is respectively connected to the two ends of the transmission shaft structure 222, and the other ends of the two elastic components 223 are respectively connected to the two ends of the target part 21; the driving motor 221 drives the transmission shaft structure 222 to reciprocate, so that the target part 21 is in the first motion state or the second motion state.

[0053] Specifically, the drive motor 221 is not specifically limited, and can be a conventional rotary motor or a servo motor. In the present embodiment, the drive motor 221 can be arranged at any side position along the length direction of the groove structure, and its driving end is arranged relative to the accommodating space. The connection mode between the two ends of the transmission shaft structure 222 and the two elastic components 223 can be connected by interference fit, and the connection mode between the transmission shaft structure 222 and the drive motor 221 can be to set a transmission shaft connecting end 224 on the transmission shaft structure 222, and connect the transmission shaft connecting end 224 to the drive motor 221 through a coupling. In the present embodiment, a servo motor can be used as the drive motor 221, and a reducer is arranged between the drive motor 221 and the transmission shaft structure 222 to realize the drive of the drive motor 221 to the transmission shaft structure 222. The elastic component 223 can be a combination of a connecting rod and a spring, or a combination of an elastic airbag and an air column, and is not specifically limited. The elastic component 223 and the transmission shaft structure 222 may be connected by interference fit or by welding, without any specific limitation, as long as the elastic component 223 can rotate around the axis of the transmission shaft structure 222 .

[0054] In this embodiment, the elastic component 223 can be composed of a compression spring and a telescopic connecting rod. The compression spring is built into the telescopic connecting rod. The two ends of the telescopic connecting rod are respectively connected to the transmission shaft structure 222 and the target part 21. When the telescopic connecting rod is retracted, the built-in compression spring can be compressed. When the target part 21 abuts against the component to be detected 7, the telescopic connecting rod is retracted and compresses the compression spring, so that the compression spring provides a reset reaction force, providing the target part 21 with a pressing force on the component to be detected 7. At the same time, when the transmission shaft structure 222 rotates, the compression spring is used to realize the movement of the target part 21 in the groove structure along the extension direction of the groove structure. The size of the pressing force provided by the target part 21 to the component to be detected 7 can be changed by replacing the compression spring or changing the distance between the transmission shaft structure 222 and the bottom of the groove structure.

[0055] During operation, after the component to be tested 7 is set on the bearing component 1, the driving motor 221 drives the transmission shaft structure 222 to rotate along the first rotation direction, so that the target part 21 presses the component to be tested 7, and moves from the top of the groove on one side of the groove structure along the first side wall 11 to the bottom of the groove of the groove structure to achieve the first motion state. After reaching the bottom of the groove, the driving motor 221 drives the transmission shaft structure 222 to rotate along the second rotation direction opposite to the first rotation direction, so that the target part 21 rotates to the top of the groove on the other side of the groove structure, and moves from the top of the groove on the other side along the first side wall 11 to the bottom of the groove of the groove structure to achieve the second motion state. In this way, the component to be tested can be tested.

[0056] In some embodiments, the groove structure has a first size along the first direction, and the groove structure has a second size along the second direction, and the second size is not smaller than the first size.

[0057] Specifically, the first direction is the depth direction of the groove structure, the first dimension is the depth dimension of the groove structure, the second direction is the width direction of the groove structure, the second dimension is the opening dimension of the groove structure, and the ratio of the first dimension to the second dimension can be 0.8:2.2. At the same time, in this embodiment, the ratio of the diameter of the roller structure to the second dimension can be 0.8-1.2:6, and the length of the groove structure and the length of the roller structure are not less than the width of the component to be detected 7. It is not specifically limited, and can be selected according to the size of the component to be detected 7. Such a setting can make the component to be detected 7 better fit with the first side wall 11, and prevent the problem of difficulty in placing the component to be detected 7 into the accommodating space.

[0058] like Figure 1 , Figure 2 As shown, in some embodiments, the detection device also includes: a supporting component 1 having a first side and a second side relatively arranged, a light source component 3 is arranged on the first side, and an optical detection component 4 is arranged on the second side, and the light source component 3 and the optical detection device are used to detect the bending area of ​​the component to be detected 7 through cooperation, and the accommodating space is used to set the bending area of ​​the component to be detected 7.

[0059] Specifically, the bearing component 1 has a first side and a second side along the length direction of the groove structure. The light source component 3 is not specifically limited, and it only needs to be able to emit light into the accommodating space. The optical detection component 4 can be a combination of a processing device and an optical sensor, and is not specifically limited. The light source component 3 emits a pipeline and illuminates the component to be detected 7. The optical detection component 4 analyzes the stratification of the component to be detected 7 according to the changes in the received light, and determines whether the component to be detected 7 is stratified. Such a setting can make the detection result of the component to be detected 7 more accurate.

[0060] like Figure 1 , Figure 2As shown, in some embodiments, a display component 5 is disposed on the second side of the carrier component 1 , and the display component 5 is connected to the optical detection component 4 to display and output the detection result of the component to be detected 7 .

[0061] Specifically, the display component 5 can be a display screen, and the display component 5 and the optical detection component 4 can be connected through a data transmission line. The optical detection component 4 transmits the analysis result to the display component 5 for display, so that the operator can know the detection result more intuitively.

[0062] like Figures 1 to 3 As shown, in some embodiments, the detection device further includes: a limiting component 6, which is connected to the second side wall 12 of the supporting component 1, the second side wall 12 intersects with the first side wall 11, and the limiting component 6 is used to limit the component 7 to be detected.

[0063] Specifically, the limiting component 6 can be a clamping component, or a vacuum suction cup, and is not specifically limited. In the present embodiment, two vacuum suction cups can be used as the limiting component 6. The second side wall 12 can be understood as the side walls on both sides of the groove top of the groove structure forming the second side wall 12, and intersecting with the first side wall 11. The suction ends of the two vacuum suction cups are arranged opposite to each other, and the connection method with the second side wall 12 can be through screw connection or through clamping structure. When the component 7 to be detected is arranged in the accommodating space, there will be a part of the pressing area outside the groove structure, and the vacuum suction cup will hold the pressing area to prevent the component 7 to be detected from moving due to the movement of the target part 21.

[0064] In some embodiments, an automatic loading device can be added to the detection device. The automatic loading device can be a robot or a multi-axis linkage clamping device, without specific limitation. The automatic loading device can grab the component 7 to be detected outside and place it in the accommodating space, further increasing the degree of automation of the detection device.

[0065] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
