[0077] References to "embodiments" in this specification mean that particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Without conflict, the various embodiments in the present application can be combined with each other.

[0078] It should be noted that the thickness, length, width, etc. of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width, etc. of the integrated device, are only for illustrative purposes and should not constitute any limitation to the present application.

[0079] The product of the embodiment of the present application includes a first component and a second component connected to each other. Specifically, the first component, such as a mobile phone frame, and the second component, such as an SP board (flexible printed circuit board), are connected by welding. If there is a situation of poor welding between the frame and the SP board, the product quality is unqualified. To control the product quality, it is necessary to detect whether there is a situation of poor welding between the frame and the SP board.

[0080] Currently, by pressing the SP board, the operator observes whether the SP board is separated from the frame. If the SP board is partially separated from the frame, it is determined that there is poor welding between the frame and the SP board. However, relying on the operator's visual inspection, the judgment criteria are different and there is a possibility of misjudgment.

[0081] The embodiment of the present application provides a detection device for detecting whether there is poor welding between a first component and a second component in a product. The detection device includes a carrying module, a pushing module, and a driving member. The carrying module includes a base and a conductive component. The base is used to position the product, and the conductive component is arranged on the base. The pushing module includes a moving member, a pressing component, and a holding component. The pressing component and the holding component are arranged on the moving member. The holding component is used to press the product. The pressing component includes a preloading elastic member and a push rod. The preloading elastic member is used to provide a preset elastic force acting on the push rod. The driving member is connected to the moving member and is used to drive the moving member to move towards the carrying module so that the moving member abuts on the base. The preloading elastic member is used to apply a preset elastic force to the position to be measured of the product on the base through the push rod, so as to form a conductive circuit between the pressing component and the conductive component to detect defective products in the product.

[0082] In the above detection device, the conductive component is electrically connected to the pressing component. The driving member drives the moving member to move towards the base, so that the push rod can apply a preset elastic force to the position to be measured of the product towards the base. If the position to be measured of the product is firmly connected to the product, the pressing component and the conductive component cannot form an electrical conduction loop, and at this time, the product is determined to be qualified; if there is a situation of poor soldering at the position to be measured of the product, the position to be measured of the product is not firmly connected to the product, and the pressing component and the conductive component form an electrical conduction loop. At this time, the product has poor soldering and is determined to be unqualified. Such a detection device has a high degree of automation, a unified judgment standard, and is not prone to misjudgment.

[0083] Next, with reference to the accompanying drawings, embodiments of the present application will be further described.

[0084] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a detection device 100 for detecting a product 200. The product 200 includes a first component 210 and a second component 220 connected to each other.

[0085] In some embodiments, the first component 210 and the second component 220 are connected together by soldering, and the detection device 100 is used to detect whether there is poor soldering between the first component 210 and the second component 220. Among them, poor soldering means that only a small amount of solder is used to solder at the solder joint of the first component 210 and the second component 220, resulting in a loose solder joint at the solder joint of the first component 210 and the second component 220.

[0086] Please refer to Figure 3 , the detection device 100 includes a carrier module 10, a pushing module 20 and a driving member 30 (see Figure 2 ). The carrier module 10 and the pushing module 20 are arranged opposite to each other, and are respectively arranged on opposite sides of the product 200 when detecting the product. The driving member 30 is used to drive the pushing module 20 to move towards the carrier module 10.

[0087] Please refer to Figure 4 , the carrier module 10 includes a base 11 and a conductive component 12, and the conductive component 12 is arranged on the base 11. The base 11 is used to position the position of the first component 210. Please refer to Figure 5 , the pushing module 20 includes a moving member 21, a pressing component 22 and a holding component 24, and the pressing component 23 and the holding component 24 are arranged on the moving member 21. When the driving member 30 drives the pushing module 20 to move to the carrier module 10, the moving member 21 abuts against the base 11, the holding component 24 abuts against the product 200, and the pressing component 22 applies a preset elastic force to the position to be measured of the product 200 on the base 11 to detect defective products in the product 200. Specifically, there are multiple holding components 24, and the multiple holding components 24 are respectively arranged around the moving member 21, and the pressing component 22 is arranged on the diagonal of the moving member 21 and is adjacent to the holding component.

[0088] In some embodiments, the position to be measured of the product 200 is the connection position between the second component 220 and the first component 210. The pressing assembly 22 applies a preset elastic force to the second component 220 to detect a soldering defect between the second component 220 and the first component 210.

[0089] Please refer to Figure 6 and Figure 7 , the pressing assembly 22 includes a preloading elastic member 222 and a push rod 223. The preloading elastic member 222 is used to provide a preset elastic force and act on the push rod 223. Please refer to Figure 5 , the driving member 30 is connected to the moving member 21. When the driving member 30 drives the moving member 21 to move to the carrying module 10, the preloading elastic member 222 applies a preset elastic force to the second component 220 through the push rod 223.

[0090] In some embodiments, the abutting assembly 24 includes a cover plate 241, an abutting elastic member 242, and a pressing plate 243. The cover plate 241 is fixedly connected to the moving member 21. The abutting elastic member 242 is respectively connected to the moving member 21 and the pressing plate 243. The pressing plate 243 is located on one side of the moving member 21 facing the carrying module 10 (see Figure 9 ). When the driving member 30 drives the moving member 21 to move to the carrying module 10, the abutting elastic member 242 applies a preset pressure to the first component 210 through the pressing plate 243 to abut the product 200 on the base 11 to prevent the first component 210 from shifting.

[0091] Please refer to Figure 8 , if there is a soldering defect between the second component 220 and the first component 210, the pressed position of the second component 220 is not firmly connected to the first component 210. The second component 220 disengages from the first component 210 under the preset elastic force. The push rod 223 drives the second component 220 to move towards the base 11, causing the pressing assembly 22, the second component 220, and the conductive assembly 12 to be in electrical contact in sequence to form an electrical conduction path. At this time, it is determined that the product 200 is unqualified. Please refer to Figure 6 and Figure 7 , if the pressed position of the second component 220 is firmly connected to the first component 210, the second component 220 remains stationary relative to the first component 210 under the preset elastic force. The second component 220 is not in electrical contact with the conductive assembly 12. The second component 220 is spaced from the conductive assembly 12, and the conductive assembly 12, the pressing assembly 22, and the second component 220 cannot form an electrical conduction path. At this time, it can be determined that the product 200 is qualified. Such a detection device 100 has a high degree of automation, a unified judgment standard, and is not prone to misjudgment.

[0092] Please refer to Figure 6 , in some embodiments, the conductive assembly 12 and the pressing assembly 22 are electrically connected through a wire 80.

[0093] In some embodiments, the preset elastic force is set to 1.5KG to prevent the push rod 223 from applying too much pressure to the second element 220 and damaging the qualified product 200. In addition, according to the use requirements, the preset elastic force can also be greater than or less than 1.5KG, which is not limited here.

[0094] In some embodiments, the moving member 21 is a metal member, and the wire 80 is electrically connected to the conductive component 12 and the moving member 21, thereby electrically connecting the conductive component 12 and the pressing component 22. By electrically connecting the wire 80 to the moving member 21, the pressing component 22 in contact with the moving member 21 can be electrically connected to the conductive component 12, which facilitates the arrangement of the wire 80. Compared with connecting the conductive component 12 and the pressing component 22 with the wire 80, the wire 80 connected to the pressing component 22 is more likely to become tangled during the movement of the moving member 21.

[0095] In some embodiments, a conductive screw 212 is threadedly connected to one side of the movable member 21, and the wire 80 is connected to the conductive screw 212. As an exemplary embodiment, the wire 80 is wound around the conductive screw 212. By rotating the conductive screw 212, the wire 80 can be connected to the movable member 21 or removed from the movable member 21, thereby electrically connecting or disconnecting the pressing component 22 from the conductive component 12.

[0096] See also Figure 4 、 Figure 6 and Figure 7 In some embodiments, a first through hole 1101 is provided on the base 11, and the conductive component 12 is passed through the first through hole 1101. The conductive component 12 includes a support rod 121, a pressing elastic member 122, and a conductive column 123 connected in sequence. The support rod 121 is provided on the side of the base 11 away from the push module 20, and is used to electrically connect to the pressing component 22 through the wire 80. The pressing elastic member 122 is used to reset the conductive column 123. The conductive column 123 is used to electrically contact the second element 220 when the second element 220 moves toward the base 11, so that the conductive column 123, the pressing elastic member 122, the support rod 121 and the pressing component 22 form a conductive loop.

[0097] In addition, the pressing elastic member 122 also plays a role in buffering and shock absorption. When the second element 220 moves toward the base 11 and electrically contacts the conductive column 123, the pressing elastic member 122 is elastically compressed, thereby buffering and shock absorbing the second element 220 and the conductive column 123, thereby preventing the second element 220 or the conductive column 123 from being damaged due to a large interaction force between the second element 220 and the conductive column 123 when the second element 220 moves toward the conductive column 123 and contacts the conductive column 123.

[0098] In some embodiments, the conductive component 12 further includes a support seat 124, which is provided on a side of the base 11 facing away from the push module 20. The support rod 121 is threadedly connected to the support seat 124 and extends toward the first through hole 1101. The pressing elastic member 122 is sleeved on the support rod 121 and abuts against the conductive column 123. The wire 80 is wound around the support rod 121, and the wire 80 can be fixed between the support rod 121 and the support seat 124 by rotating the support rod 121. The support rod 121 electrically contacts the pressing elastic member 122, and the pressing elastic member 122 electrically contacts the conductive column 123. In this way, the conductive component 12 and the pressing component 22 are electrically connected through the wire 80. The support rod 121 can also be removed from the support seat 124 by rotating the support rod 121, so that the conductive component 12 and the pressing component 22 are electrically disconnected. As an illustrative example, the support rod 121 is a screw.

[0099] The pressing elastic member 122 sleeved on the support rod 121 elastically expands and contracts along the extension direction of the support rod 121, and the hole wall of the first through hole 1101 contacts the pressing elastic member 122. The support rod 121 and the hole wall of the first through hole 1101 guide the pressing elastic member 122 to elastically expand and contract, thereby preventing the pressing elastic member 122 from shaking during elastic expansion and contraction, and making the pressing elastic member 122 less prone to fatigue damage.

[0100] See also Figure 4 In some embodiments, the support base 124 is fixedly connected to the base 11 by screws.

[0101] See also Figure 5 、 Figure 6 and Figure 7 In some embodiments, the moving member 21 is provided with a second through hole 2101. The push rod 223 is provided through the second through hole 2101. The pressing assembly 22 further includes a pressing seat 221, which is connected to the side of the moving member 21 facing away from the supporting module 10. The pre-stressed elastic member 222 is respectively connected to the pressing seat 221 and the push rod 223, so that the push rod 223 can apply a preset elastic force to the second element 220, thereby preventing the push rod 223 from applying excessive force to the second element 220, thereby preventing the qualified product 200 from being damaged.

[0102] When the push rod 223 applies pressure to the second element 220, the pre-stressed elastic member 222 is elastically compressed, thereby buffering and absorbing shock for the second element 220 and the push rod 223, and preventing the push rod 223 from generating a large interaction force at the moment of contact with the second element 220, which may cause damage to the second element 220 or the push rod 223.

[0103] See also Figure 5 In some embodiments, the pressing seat 221 is fixedly connected to the moving member 21 by screws.

[0104] See also Figure 6 and Figure 7, in some embodiments, a groove 2231 is provided at one end of the push rod 223 facing the pressing seat 221. A receiving groove 2211 is provided at one end of the pressing seat 221 facing the push rod 223. The preloading elastic member 222 is disposed in the groove 2231 and the receiving groove 2211. The push rod 223 can move within the receiving groove 2211, so that the preloading elastic member 222 elastically expands and contracts. The groove 2231 and the receiving groove 2211 facilitate the installation of the preloading elastic member 222. The groove wall of the groove 2231 contacts the preloading elastic member 222 to guide the elastic expansion and contraction of the preloading elastic member 222, prevent the preloading elastic member 222 from swaying during elastic expansion and contraction, and make the preloading elastic member 222 not easily damaged by fatigue.

[0105] When the push rod 223 moves towards the base 11 and presses the second element 220, the push rod 223 moves relative to the moving member 21 within the second through hole 2101, causing the push rod 223 to move towards the pressing seat 221 within the receiving groove 2211, and the preloading elastic member 222 is elastically compressed, thereby buffering and damping the second element 220 and the push rod 223.

[0106] In some embodiments, the elastic compression length of the preloading elastic member 222 can be controlled by the moving distance of the moving member 21 towards the base 11, so that the magnitude of the pressure generated by the push rod 223 on the second element 220 can be controlled.

[0107] Please refer to Figure 5 , in some embodiments, the pushing module 20 further includes a connecting member 23. The connecting member 23 includes a bracket 231, a connecting block 232, and a telescopic rod 233. The bracket 231 is used to mount the driving member 30. The telescopic rod 233 is connected between the moving member 21 and the bracket 231. The connecting block 232 is respectively connected to the moving member 21 and the driving member 30. The telescopic rod 233 expands and contracts in the vertical direction to guide the connecting block 232 to drive the moving member 21 to move in the vertical direction under the drive of the driving member 30, restricting the movement of the moving member 21 in the vertical direction to prevent the moving member 21 from swaying during movement.

[0108] In some embodiments, the driving member 30 is a cylinder.

[0109] In some embodiments, the number of telescopic rods 233 is two, and the two telescopic rods 233 are respectively disposed on both sides of the connecting block 232, making the moving member 21 more stable during vertical movement.

[0110] Please refer to Figure 5 , in some embodiments, the telescopic rod 233 includes a connecting rod 2331 and a moving rod 2332. The connecting rod 2331 is fixedly connected to the bracket 231, the moving rod 2332 is fixedly connected to the moving member 21, the connecting rod 2331 is sleeved on the moving rod 2332, and the moving rod 2332 can move relative to the connecting rod 2331 in the vertical direction, enabling the moving member 21 to move in the vertical direction.

[0111] Please refer to Figure 4 and Figure 10 In some embodiments, a positioning pin 111 is provided on the base 11. A positioning hole 2201 is provided on the second element 220. The positioning pin 111 is used to pass through the positioning hole 2201 to position the second element 220 and prevent the second element 220 from shifting.

[0112] In some embodiments, a foolproof pin 113 is provided on the base 11. The foolproof pin 113 is used to position the installation orientation of the material, so as to prevent the product 200 from being installed backwards when the product 200 is installed on the base 11.

[0113] Please refer to Figure 4 and Figure 9 In some embodiments, a registration hole 112 is provided on one side of the base 11 facing the pushing module 20. A registration post 211 is provided on one side of the moving member 21 facing the carrying module 10. The registration post 211 is inserted into the registration hole 112 when the push rod 223 presses on the second element 220 towards the base 11, so as to position the relative position between the carrying module 10 and the pushing module 20, so that the push rod 223 can press on the preset position of the second element 220 towards the base 11.

[0114] In some embodiments, the preset position is set as the welding position 230 between the second element 220 and the first element 210, so that the pressing assembly 22 acts on the welding position 230 between the second element 220 and the first element 210, thereby detecting whether the welding position between the second element 220 and the first element 210 is firmly welded.

[0115] Please refer to Figure 6 and Figure 10 In some embodiments, the first element 210 is provided on the periphery of the second element 220. There are two welding positions 230 between the first element 210 and the second element 220. The two welding positions 230 are respectively provided on the opposite sides of the second element 220. Both the conductive assembly 12 and the pressing assembly 22 are two. One conductive part can press on one welding position 230 to simultaneously detect whether the two welding positions 230 are firmly welded. Multiple points are detected simultaneously and the detection results are automatically judged, with fast detection speed and high efficiency.

[0116] In some embodiments, the product 200 is a mobile phone case, the first element 210 is a mobile phone frame, and the second element 220 is a flexible printed circuit board. Both the flexible printed circuit board and the moving member 21 can conduct electricity. In addition, the product 200 can also be other electronic products 200.

[0117] Please refer to Figure 1 and Figure 2, in some embodiments, the detection device 100 further includes a workbench 40, a display panel 50, and control buttons 60. The carrier module 10 and the pushing module 20 are both disposed on the workbench 40. The control buttons 60 are used to control the operation of the driving member 30. When the pressing assembly 22, the second element 220, and the conductive assembly 12 are in electrical contact in sequence, the display panel 50 displays that the conductive assembly 12, the pressing assembly 22, and the second element 220 form a conductive circuit. When the second element 220 is not in electrical contact with the conductive assembly 12, the display panel 50 displays that the conductive assembly 12, the pressing assembly 22, and the second element 220 are not conducting. Thus, it can be determined whether the product 200 is qualified through the detection device 100.

[0118] In some embodiments, the base 11 and the bracket 231 are both installed on the workbench 40 to position the carrier module 10, the pushing module 20, and the driving member 30.

[0119] In some embodiments, the detection device 100 further includes a protective cover 70. The protective cover 70 is disposed on the workbench 40, and the carrier module 10, the pushing module 20, and the driving member 30 are all disposed inside the protective cover 70. The protective cover 70 has a viewing window 71 to observe the states of the carrier module 10 and the pushing module 20 through the viewing window 71.

[0120] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the disclosure scope of the present application.
