Description

Technical Field

[0001] This application relates to the technical field of detection devices, and particularly to a detection device. Background Art

[0002] Currently, in order to reduce the volume of electronic devices, a stacked board mode is usually adopted in which a radio frequency layer, a connection line layer, and a substrate layer are stacked in sequence, and the radio frequency module and the substrate layer are connected through the connection line layer.

[0003] However, the battery interface is integrated on the radio frequency module, so that when the radio frequency module is removed, the repair method for the connection line layer and the substrate layer is blind repair. Blind repair requires multiple assembly detections with the radio frequency module after the blind repair is completed to confirm whether the repair is correct, which affects the repair efficiency. At the same time, blind repair is likely to damage the substrate layer, resulting in a high scrap rate of the substrate layer. Utility Model Content

[0030] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0031] The present application provides a detection device 10. Refer to Figures 1 to 4 As shown, the detection device 10 may include: a main body 11 and a connection structure 12. The main body 11 is provided with a clamping space 111 for clamping a workpiece to be detected 20; the connection structure 12 is arranged on the main body 11, at least a part of which can be opposite to the target area of the clamping space 111, and a first connection part 121 is arranged on the part of the connection structure 12 opposite to the target area; wherein, when the workpiece to be detected 20 is clamped in the clamping space 111, the second connection part of the workpiece to be detected 20 is correspondingly arranged in the target area and electrically connected to the first connection part 121, so that power can be supplied and signal transmission can be carried out between the first connection part 121 and the second connection part.

[0032] That is to say, the detection device 10 is provided with a main body 11 and a connection structure 12. The main body 11 can clamp the workpiece to be detected 20, and the first connection part 121 on the connection structure 12 can be opposite to the second connection part of the clamped workpiece to be detected 20 to achieve electrical connection between each other, so that power can be supplied and signal transmission can be carried out between the first connection part 121 and the second connection part. Here, the workpiece to be detected 20 can be an integrated body of a connection line layer and a substrate without a power interface and a signal interface. In this way, the detection device 10 can supply power to the integrated body and transmit detection signals, so that bad point positions and other defects can be confirmed under the condition of power supply and real-time transmission of detection signals, and then accurate maintenance can be carried out to improve the maintenance efficiency and reduce the probability of damaging the workpiece to be detected 20 at the same time.

[0033] Among them, a probe 122 adapted to the second connection part can be arranged on the first connection part 121, so that after the first connection part 121 and the second connection part are connected, the probe 122 on the first connection part 121 contacts corresponding solder joints, pins, etc. on the second connection part to be electrically connected to each other. For example: the probe 122 may include: a power supply probe, a ground probe, a test signal probe, etc. The power supply probe can supply power to the second connection part; the number of ground probes can be 3-5 to achieve grounding of the first connection part 121 and the second connection part, so as to ensure safety and reliability during the detection process; the test signal probe can transmit signals to the second connection part, such as transmitting USB data signals, software download signals, debug instruction sending / receiving signals, USB screen mirroring display signals, etc. to the workpiece to be detected 20, and then bad points and other defects existing in the workpiece to be detected 20 can be confirmed according to whether the workpiece to be detected 20 has corresponding executions.

[0034] The connection structure 12 can be arranged above the main body 11, can also be arranged on the side of the main body 11, and can also be arranged below the main body 11; when the connection structure 12 is arranged below the main body 11 and protrudes below the main body 11, a support structure can be arranged below the main body 11, and the height of the support structure is greater than the height of the connection structure 12 to stably support the main body 11. For example: Refer toFigures 1 to 4 As shown, four support columns 110 are provided below the main body 11 to stably support the main body 11.

[0035] In some embodiments, referring to Figures 1 to 4 As shown, the main body 11 may include: a carrier plate 112 and a cover plate 113, and the carrier plate 112 and the cover plate 113 have a stacked state and a non-stacked state; when in the stacked state, the first to-be-detected plate and the second to-be-detected plate arranged in a stacked manner of the to-be-detected member 20 are distributed along the clamping direction of the clamping space 111 and are clamped in the clamping space 111; when in the non-stacked state, the to-be-detected member 20 is not clamped in the clamping space 111.

[0036] That is to say, when the carrier plate 112 and the cover plate 113 move relative to each other to be stacked, the clamping space 111 formed by the carrier plate 112 and the cover plate 113 can clamp the to-be-detected member 20, and the to-be-detected member 20 to be clamped may include a first to-be-detected plate 21 and a second to-be-detected plate 22 that are stacked and clamped together; when the carrier plate 112 and the cover plate 113 move relative to each other to be non-stacked, the clamping space 111 is opened so that the to-be-detected member 20 can be taken out, so that the to-be-detected member 20 is not clamped in the clamping space 111; thus, the detection device 10 can clamp the to-be-detected member 20, energize the to-be-detected member 20, and transmit signals, so as to confirm defects such as bad points in the to-be-detected member 20, and the to-be-detected member 20 can also be taken out from the clamping space 111 after the confirmation is completed. Here, as Figure 4 As shown, the first to-be-detected plate 21 may be a connection circuit layer, the second to-be-detected plate 22 may be a substrate layer, the first to-be-detected plate 21 and the second to-be-detected plate 22 are stacked together, and the clamping direction of the to-be-detected member 20 by the carrier plate 112 and the cover plate 113 may be consistent with the stacking direction of the first to-be-detected plate 21 and the second to-be-detected plate 22.

[0037] Among them, the first dimensions (including length and width) of the carrier plate 112 and the cover plate 113 can be the same, so that when the carrier plate 112 and the cover plate 113 are in a stacked state, the peripheral sides of the carrier plate 112 and the cover plate 113 are flush, which can improve the visual effect of the main body 11. In this setting, in order to enable the user to apply force to one of the carrier plate 112 and the cover plate 113 more conveniently, so that the carrier plate 112 and the cover plate 11 are switched from the stacked state to the non-stacked state, a groove 1121 can be provided on the peripheral side surface of the carrier plate 112 (or the cover plate 113), so that the finger tip or operating tool of the user can extend into the groove 1121 and apply force in a direction away from the cover plate 113 (or the carrier plate 112), so as to conveniently and quickly realize the switching of the carrier plate 112 and the cover plate 11 from the stacked state to the non-stacked state; the dimensions (including length and width) of the carrier plate 112 and the cover plate 113 can also be different, so that when the carrier plate 112 and the cover plate 113 are in a stacked state, force can be applied to the edge portions where the carrier plate 112 and the cover plate 113 are not aligned with each other, so that the carrier plate 112 and the cover plate 113 are switched from the stacked state to the non-stacked state.

[0038] In some embodiments, the clamping space 111 may include one of the following: the side of the carrier plate 112 facing the cover plate 113 is recessed to have the clamping space 111; the side of the cover plate 113 facing the carrier plate 112 is recessed to have the clamping space 111; the carrier plate 112 and the cover plate 113 cooperate to have the clamping space 111. For example: the side of the carrier plate 112 facing the cover plate 113 is recessed with a clamping space 111 adapted to the workpiece 20 to be detected, and the part of the cover plate 113 corresponding to the clamping space 111 is a plane or a convex part so as to be able to squeeze the workpiece 20 in the clamping space 111; another example: the side of the cover plate 113 facing the carrier plate 112 is recessed with a clamping space 111 adapted to the workpiece 20 to be detected, and the part of the carrier plate 112 corresponding to the clamping space 111 is a plane or a convex part so as to be able to squeeze the workpiece 20 in the clamping space 111; still another example: the side of the cover plate 113 facing the carrier plate 112 is recessed with a first space adapted to a part of the workpiece 20 to be detected, and the position of the carrier plate 112 corresponding to the first space is recessed with a second space adapted to another part of the workpiece 20 to be detected. Then, when the carrier plate 112 and the cover plate 113 are stacked on each other, the first space and the second space are spliced to complete the clamping of the workpiece 20 to be detected; three setting methods are provided here for flexible selection.

[0039] In some embodiments, the cover plate 113 and the carrier plate 112 are detachably connected. They are close to each other to be in a stacked state and away from each other to be in a non-stacked state; alternatively, the cover plate 113 is rotatably connected to the carrier plate 112 and rotates relative to each other to switch between the stacked state and the non-stacked state; or, the cover plate 113 and the carrier plate 112 are connected by an elastic member. When the cover plate 113 and the carrier plate 112 are close to each other and compress the elastic member, they are in a stacked state, and when they are away from each other, they are in a non-stacked state. Here, three different setting methods are provided, and each setting method can realize the switching between the stacked state and the non-stacked state of the cover plate 113 and the carrier plate 112. During specific implementation, one of the setting methods can be flexibly selected; of course, other setting methods other than the above three can also be selected.

[0040] In one example, the cover plate 113 and the carrier plate 112 are connected by screws so that the cover plate 113 and the carrier plate 112 are in a stacked state. In the stacked state, the clamping space 111 between the cover plate 113 and the carrier plate 112 can clamp the workpiece to be detected 20; after rotating to remove the screws and applying a force in the direction away from the carrier plate 112 to the cover plate 113, the cover plate 113 and the carrier plate 112 are separated from each other to switch to the non-stacked state. At this time, the clamping space 111 is exposed so that the workpiece to be detected 20 can be taken out or the next workpiece to be detected 20 can be put in.

[0041] In one example, one end of the cover plate 113 is rotatably connected to one end of the carrier plate 112. After the other end of the cover plate 113 rotates in the direction close to the other end of the carrier plate 112, the other end of the cover plate 113 is stacked on the other end of the carrier plate 112 so that the cover plate 113 and the carrier plate 112 are in a stacked state. At this time, the clamping space 111 between the cover plate 113 and the carrier plate 112 can clamp the workpiece to be detected 20; after the other end of the cover plate 113 rotates in the direction away from the other end of the carrier plate 112, the clamping space 111 is exposed so that the workpiece to be detected 20 can be taken out or the next workpiece to be detected 20 can be put in.

[0042] In one example, the cover plate 113 and the carrier plate 112 are respectively provided with a first blind hole and a second blind hole. The two ends of the elastic member (such as a spring) are respectively connected to the first blind hole and the second blind hole. In this way, when the elastic member is compressed by squeezing in the direction of approaching each other, the elastic member is compressed and the cover plate 113 and the carrier plate 112 are stacked on each other. At this time, the clamping space 111 between the cover plate 113 and the carrier plate 112 can clamp the workpiece to be detected 20; when the force squeezing the elastic member is removed, the cover plate 113 and the carrier plate 112 are reset under the elastic recovery force of the elastic member. At this time, the clamping space 111 is exposed so that the workpiece to be detected 20 can be taken out or the next workpiece to be detected 20 can be put in.

[0043] In some embodiments, refer to Figures 2 to 4As shown, the carrier plate 112 is provided with a first magnetic attraction member 1122; the cover plate 113 is provided with a second magnetic attraction member 1131; when the cover plate 113 and the carrier plate 112 are in a stacked state, the second magnetic attraction member 1131 and the first magnetic attraction member 1122 attract each other. Here, the carrier plate 112 and the cover plate 113 can be detachably connected, rotatably connected, or connected by an elastic member. When the carrier plate 112 and the cover plate 113 move relative to each other to be stacked, the first magnetic attraction member 1122 and the second magnetic attraction member 1131 can attract each other, and the cover plate 113 and the carrier plate 112 are vertically buckled and magnetically connected, and are relatively vertically buckled and magnetically attracted to switch between the stacked state and the non-stacked state, so that the cover plate 113 and the carrier plate 112 in the stacked state are more firmly connected, and the first connecting portion 121 and the second connecting portion can stably apply a force to squeeze and approach each other, so that the power supply and signal transmission between the connecting structure 12 and the component to be detected 20 are more stable.

[0044] Among them, the number of the first magnetic attraction members 1122 can be one or more, and the number of the second magnetic attraction members 1131 can be one or more; for example: the number of the first magnetic attraction members 1122 is one, the number of the second magnetic attraction members 1131 is multiple, and each second magnetic attraction member 1131 is opposite to the first magnetic attraction member 1122.

[0045] In some embodiments, referring to Figure 1 and Figure 3 As shown, the carrier plate 112 is provided with a first limiting portion 1123; the cover plate 113 is provided with a second limiting portion 1132; when the cover plate 113 and the carrier plate 112 are in a stacked state, the first limiting portion 1123 and the second limiting portion 1132 are connected; among them, one of the first limiting portion 1123 and the second limiting portion 1132 is a concave portion, and the other is a convex portion adapted to the concave portion. In this way, during the process of the relative movement of the carrier plate 112 and the cover plate 113 to be stacked or non-stacked, the convex portion is inside the concave portion and moves along the concave portion, so as to guide the relative movement of the carrier plate 112 and the cover plate 113.

[0046] Among them, the number of the first limiting portions 1123 can be one or more, and the number of the second limiting portions 1132 can be one or more; for example: referring to Figure 1 and Figure 3 As shown, two opposite corner positions on one side of the carrier plate 112 corresponding to the cover plate 113 are respectively provided with first limiting portions 1123, and the cover plate 113 is provided with second limiting portions 1132 at positions corresponding to the first limiting portions 1123.

[0047] In some embodiments, referring to Figures 1 to 4As shown, the cover plate 113 and / or the carrier plate 112 are provided with a hollowed-out portion 114 communicating with the clamping space 111. That is to say, the cover plate 113 is provided with a hollowed-out portion 114 communicating with the clamping space 111; or, the carrier plate 112 is provided with a hollowed-out portion 114 communicating with the clamping space 111; or, both the cover plate 113 and the carrier plate 112 are provided with hollowed-out portions 114 communicating with the clamping space 111. Here, the hollowed-out portion 114 can prevent the workpiece 20 to be detected from being completely blocked, and the hollowed-out portion 114 forms an operation space / cleaning space, so that tools such as maintenance tools / cleaning tools can pass through the hollowed-out portion 114 to the clamping space 111 to perform maintenance operations or cleaning operations on the workpiece 20 to be detected. When the maintenance tool passes through the hollowed-out portion 114 to the clamping space 111, real-time maintenance is performed according to defects such as bad points confirmed by power-on and signal transmission. In this way, the maintenance efficiency can be improved, and the detection tool can also be inserted into the clamping space 111 through the hollowed-out portion 114 to detect and analyze the workpiece 20 in the clamping space 111 and locate the defective defects; when the cleaning tool passes through the hollowed-out portion 114 to the clamping space 111, the surface of the workpiece 20 corresponding to the hollowed-out portion 114 can be cleaned.

[0048] Among them, as Figures 1 to 4 shown, when the cover plate 113 and the carrier plate 112 are respectively provided with hollowed-out portions 114 communicating with the clamping space 111, the hollowed-out portion 114 of the cover plate 113, the clamping space 111 and the hollowed-out portion 114 of the carrier plate 112 can be arranged in sequence to form a structure with hollowed-out portions on both sides on the main body 11. In this way, the first workpiece 21 to be detected located in the clamping space 111 is opposite to the hollowed-out portion 114 on one side, and the second workpiece 22 to be detected is opposite to the hollowed-out portion 114 on the other side, so that the maintenance tool / cleaning tool can be passed through the corresponding hollowed-out portion 114 to perform maintenance or cleaning on the first workpiece 21 to be detected or the second workpiece 22 to be detected as needed.

[0049] In some embodiments, refer to Figures 1 to 4 shown, the connection structure 12 is arranged on the main body 11 and is fixed relative to the main body 11; or, the connection structure 12 is movably arranged on the main body 11, and after moving relative to the main body 11, the first connection portion 121 faces the target area. There are two setting methods to choose from.

[0050] In some embodiments, the movable setting between the connection structure 12 and the main body 11 may include: the connection structure 12 is slidably or flip-connected to the carrier plate 112, so that after sliding or flipping relative to the carrier plate 112, the first connection portion 121 faces the target area; or, the connection structure 12 is slidably or flip-connected to the cover plate 113, so that after sliding or flipping relative to the cover plate 113, the first connection portion 121 faces the target area. There are a variety of different setting methods to choose from.

[0051] When set to slide, a strip-shaped chute and a slider can be respectively arranged on two relatively sliding parts. The slider is located in the strip-shaped chute and can slide along the strip-shaped chute. A damping structure is arranged between the strip-shaped chute and the slider to maintain the position after sliding, such as maintaining the position where the first connecting part 121 faces the target area. When set to flip, a rotating structure such as a rotating shaft or a hinge can be arranged between two relatively flipping parts to achieve relative flipping.

[0052] In some embodiments, referring to Figure 3 As shown, the detection device 10 may further include: a power supply structure 13, electrically connected to the first connecting part 121. The first connecting part 121 has a probe 122 adapted to the second connecting part. The power supply structure 13 is provided with a first connection end 131 and a second connection end 132 that can be connected to a power source, and the first connection end 131 and the second connection end 132 can approach or separate from each other. Among them, the power supply structure 13 is provided with a surge protection module to filter the surge part exceeding the preset voltage provided by the first connection end 131 and the second connection end 132.

[0053] Referring to Figure 3 As shown, the power supply structure 13 can be a connecting wire. The output end of the connecting wire is connected to the probe 122, and the input end includes a first connection end 131 and a second connection end 132. The first connection end 131 and the second connection end 132 can be connected to a power source. For example, the first connection end 131 and the second connection end 132 can be plugged into a two-hole power source, and thus power can be supplied to the second connecting part. Here, the input end of the power supply structure 13 may further include, as shown in Figure 3 a USB interface end 133, so that while supplying current to the probe 122 through the same connecting wire, a USB data signal, a software download signal, a debug instruction sending / receiving signal, a USB screen mirroring display signal, etc. can be transmitted. The first connection end 131 and the second connection end 132 can approach or separate from each other to adapt to different widths between the two holes of the two-hole power source, so as to improve the versatility of the power supply structure 13. The setting of the surge protection module can filter the surge part exceeding the preset voltage provided by the first connection end 131 and the second connection end 132, so as to protect the detection device 10 and the component to be detected 20, and thus ensure the detection safety.

[0054] The development of mobile phones pursues stronger battery life, higher performance configurations and functional requirements. With the improvement of battery life, performance configurations and functional requirements, the accompanying increase in the motherboard area runs counter to the overall miniaturization trend of mobile phones. For this reason, the existing motherboard is designed as a stacked design to reduce the area of the motherboard. That is, the motherboard can include a radio frequency layer, a connection line layer and a substrate layer stacked in sequence. The radio frequency layer is provided with a battery interface, a USB interface, a high-definition digital display interface and test points. When the battery interface on the radio frequency layer is connected to the power supply, the motherboard can be powered on. And when the USB interface, high-definition digital display interface and test points on the radio frequency layer are connected to the corresponding signal transmission lines, the signal transmission of the motherboard can be realized, and then the detection and confirmation of bad points and other defects of the motherboard can be carried out. However, when the radio frequency layer is removed from the motherboard, the power supply and signal transmission lines cannot be directly connected to the connection line layer and the substrate, so that the detection and confirmation of bad points and other defects cannot be carried out. In this case, the repair method for the connection line layer and the substrate is blind repair. Blind repair requires multiple assembly detections with the radio frequency layer after the blind repair is completed to confirm whether the repair is correct. Therefore, it is impossible to analyze and locate the bad problems, which affects the repair efficiency and is difficult to improve the root cause. At the same time, blind repair is easy to damage the substrate layer, resulting in a high scrap rate of the substrate layer.

[0055] For this reason, the present application provides a detection device 10, as shown in Figures 1 to 4 shown, which includes:

[0056] A main body 11, including: a carrier plate 112 and a cover plate 113, the carrier plate 112 and the cover plate 113 are detachably connected and have a stacked state and a non-stacked state; when approaching each other to be in the stacked state, the first to-be-detected plate 21 and the second to-be-detected plate 22 arranged in a stacked manner of the to-be-detected part 20 are distributed along the clamping direction of the clamping space 111 and are clamped between the carrier plate 112 and the cover plate 113 to form the clamping space 111; when moving away from each other to be in the non-stacked state, the to-be-detected part 20 is not clamped in the clamping space 111. The carrier plate 112 is provided with a first magnetic attraction member 1122, and the cover plate 113 is provided with a second magnetic attraction member 1131. When the cover plate 113 and the carrier plate 112 are in the stacked state, the second magnetic attraction member 1131 and the first magnetic attraction member 1122 attract each other; the carrier plate 112 is provided with a first limiting portion 1123, and the cover plate 113 is provided with a second limiting portion 1132. When the cover plate 113 and the carrier plate 112 are in the stacked state, the first limiting portion 1123 and the second limiting portion 1132 are connected.

The cover plate 113 and the carrier plate 112 are respectively provided with a hollowed-out portion 114 communicating with the clamping space 111.

[0057] The connection structure 12 is arranged on the main body 11 and is fixed in position relative to the main body 11. At least a part of it can be opposite to the target area of the clamping space 111, and a first connection part 121 is arranged on the part of the connection structure 12 opposite to the target area. Wherein, when the workpiece to be detected 20 is clamped in the clamping space 111, the second connection part of the workpiece to be detected 20 is correspondingly arranged in the target area and is electrically connected to the probe 122 of the first connection part 121, so that electricity can be conducted and signals can be transmitted between the first connection part 121 and the second connection part.

[0058] The power supply structure 13 is electrically connected to the probe 122 of the first connection part 121. The power supply structure 13 is provided with a first connection end 131 and a second connection end 132 that can be connected to a power supply, and the first connection end 131 and the second connection end 132 can be close to each other or away from each other. Wherein, the power supply structure 13 is provided with a surge protection module to filter the surge part exceeding the preset voltage provided by the first connection end 131 and the second connection end 132.

[0059] Here, the second dimension (including: thickness) of the carrier plate 112 and the cover plate 113 can be within 30 mm, so that when the lengths of measuring structures such as a multimeter / an oscilloscope / a spectrum analyzer / CMW100 remain unchanged, they can pass through the corresponding hollow part 114 to measure the voltage / signal / waveform / timing, etc. on the workpiece to be detected 20.
