Abstract
Description
Technical Field
[0001] This application relates to the field of battery manufacturing technology, and in particular to a circuit board bracket testing device. Background Technology
[0002] Currently, in PACK battery module production, the continuity and solder joint defects of the PCBA (PCBA) bracket directly affect the safety and reliability of the battery module. Therefore, it is necessary to add equipment to simultaneously perform dual-mode testing of PCBA continuity and solder joint defects. (The PCBA bracket contains busbars, sockets, and fuses. The fuse is electrically connected between the busbars and sockets; this test checks for open circuits at the fuses. Unexpected electrical connections may occur in adjacent parallel busbar circuits, which is the aforementioned solder joint defect.) The current testing method is manual, involving step-by-step operations. Specifically, continuity is tested with a multimeter, followed by visual inspection or observation of solder joint defects using a magnifying glass. This method is extremely inefficient (≤200 points / hour), relies heavily on operator experience, has a false detection rate as high as 15%-20%, and requires frequent tool switching and result recording, resulting in high labor costs and susceptibility to fatigue errors. Furthermore, the test results depend on instrument readings or manual judgment, lacking a real-time, intuitive feedback mechanism. The current detection methods have the following problems: they cannot simultaneously determine continuity and solder joints; the step-by-step operation is time-consuming and inefficient; and the results of manual judgment are highly subjective and inconsistent.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0041] The following reference Figures 1 to 9 This application describes a circuit board bracket testing apparatus according to some embodiments.
[0042] See Figures 1 to 8 As shown, an embodiment of this application provides a circuit board bracket testing device, including: a workbench 1, a first support member 2, a pressing component 3, a second support member 4, a first detection member 5, a second detection member (not shown in the figure), and an indicator light 6; wherein, the workbench 1 is used to place the battery bracket to be tested; the first support member 2 is disposed on the workbench 1, and the pressing component 3 is disposed on the first support member 2; the second support member 4 is connected to the pressing component 3, the first detection member 5 and the second detection member are both disposed on the second support member 4, and the pressing component 3 can drive the second support member 4 to synchronously move the first detection member 5 and the second detection member along a first preset direction toward or away from the battery bracket on the workbench 1, so that the first detection member 5 contacts or separates from the busbar 171 on the battery bracket and the second detection member contacts or separates from the socket 172 on the battery bracket;
[0043] The first detection component 5, the second detection component, and the indicator light 6 are respectively set up; when the first detection component 5 is in contact with the busbar 171 on the battery bracket and the second detection component is in contact with the socket 172 on the battery bracket, if all the indicator lights 6 can be lit up, it is determined that the circuit on the battery bracket is connected; if all the indicator lights 6 can be lit up in only odd number sequence or only even number sequence, it is determined that there is no solder joint in the circuit on the battery bracket.
[0044] As can be seen from the structure described above, the circuit board bracket detection device provided in this application can be used to visually detect the continuity and solder joint defects of the battery bracket. The process is roughly as follows: the pressing component 3 drives the second support component 4 to move the first detection component 5 and the second detection component along the first preset direction toward the battery bracket on the workbench 1, so that the first detection component 5 contacts the busbar 171 on the battery bracket and the second detection component contacts the socket 172 on the battery bracket. When the first detection component 5 contacts the busbar 171 on the battery bracket and the second detection component contacts the socket 172 on the battery bracket, if all the indicator lights 6 can be lit, it is determined that the circuit on the battery bracket is connected. If all the indicator lights 6 can be lit in an odd-numbered sequence or an even-numbered sequence, it is determined that there is no solder joint in the circuit on the battery bracket.
[0045] As can be seen, the circuit board bracket inspection device provided in this application can quickly detect the continuity and solder joint defects of the battery bracket, reducing labor intensity, improving inspection efficiency, saving manpower and material resources, and can directly judge by the lighting status of indicator light 6, which is more intuitive and not affected by subjective human factors, making the inspection results more accurate.
[0046] Furthermore, preferably, the first detection component 5 and the second detection component are also arranged along the first preset direction.
[0047] Furthermore, preferably, the first preset direction is the vertical direction. Of course, it is not limited to this and can be selected according to actual needs.
[0048] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the pressing assembly 3 includes a sleeve 31, a pressing rod 32, a connecting member 33, and a handle 34; wherein, the sleeve 31 is fixed to the first support member 2, the pressing rod 32 is movably inserted into the sleeve 31, and the top and bottom ends of the pressing rod 32 are exposed outside the sleeve 31.
[0049] Along the first preset direction, the handle 34 and the adapter 33 are both located above the pressing rod 32; one end of the adapter 33 is rotatably connected to the first position 19 of the handle 34, and the other end of the adapter 33 is rotatably connected to the top of the pressing rod 32; the second position 20 of the handle 34 is rotatably connected to the first support member 2; the second support member 4 is connected to the bottom end of the pressing rod 32.
[0050] As can be seen from the structure described above, when the battery holder is placed on the workbench 1 and needs to be tested, the handle 34 is rotated downwards. The handle 34 will drive the adapter 33 to move, and the adapter 33 will then drive the pressing rod 32 to move. Due to the limiting effect of the sleeve 31, the pressing rod 32 can only move downwards along the first preset direction, thereby driving the second support member 4 to simultaneously drive the first detection member 5 and the second detection member to move towards the battery holder on the workbench 1 along the first preset direction until the first detection member 5 contacts the busbar 171 on the battery holder and the second detection member contacts the socket 172 on the battery holder, and then the test can be performed.
[0051] Once the test is complete, the handle 34 can be rotated upwards. The handle 34 will drive the adapter 33 to move, and the adapter 33 will then drive the pressing rod 32 to move. Due to the limiting effect of the sleeve 31, the pressing rod 32 can only move upwards along the first preset direction, thereby driving the second support member 4 to simultaneously drive the first detection member 5 and the second detection member to move away from the battery bracket on the workbench 1 along the first preset direction until the first detection member 5 separates from the busbar 171 on the battery bracket and the second detection member separates from the socket 172 on the battery bracket.
[0052] As can be seen, the above operations are simple and convenient, and help improve work efficiency and reduce labor intensity.
[0053] In this embodiment, preferably, as follows: Figure 9 As shown, the first detection component 5 includes a mounting sleeve 51, a guide rod 52, a spring 53, and a probe part 54; wherein, the mounting sleeve 51 is fixed to the second support component 4; the outer wall of the guide rod 52 is formed with a limiting boss 521 arranged around its axis;
[0054] One end of the guide rod 52 is movably inserted into the mounting sleeve 51, and the spring 53 is sleeved on the guide rod 52. The two ends of the spring 53 are respectively connected to the end of the mounting sleeve 51 and the limiting boss 521. The probe part 54 is fixedly connected to the end of the guide rod 52 away from the mounting sleeve 51.
[0055] As described above, when the handle 34 is rotated downwards, the handle 34 will drive the adapter 33 to move, and the adapter 33 will then drive the pressing rod 32 to move. Due to the limiting effect of the sleeve 31, the pressing rod 32 can only move downwards along the first preset direction, thereby driving the second support member 4 to simultaneously drive the first detection member 5 and the second detection member to move along the first preset direction toward the battery bracket on the worktable 1 until the first detection member 5 contacts the busbar 171 on the battery bracket and the second detection member contacts the socket 172 on the battery bracket. During the contact between the first detection member 5 and the busbar 171 on the battery bracket, the spring 53 will push the probe part 54 to make close contact with the busbar 171, improving the accuracy and reliability of the detection. Moreover, the spring 53 can also play a buffering role, protecting the probe part 54 and the busbar 171, and avoiding damage to the above-mentioned components due to hard collisions.
[0056] In this embodiment, preferably, as follows: Figure 4 and Figure 5 As shown, the workbench 1 has a mounting groove 102 extending along a first preset direction and is used to place the circuit board bracket 17, and the bottom wall of the mounting groove 102 has an avoidance groove 103.
[0057] As can be seen from the structure described above, the circuit board support 17 can be placed in the mounting groove 102, making the circuit board support 17 more stable and less prone to displacement. Furthermore, an avoidance groove 103 is provided on the bottom wall of the mounting groove 102 to avoid interference with the structure on the circuit board support 17, thus preventing the circuit board from warping or becoming uneven.
[0058] Furthermore, preferably, the worktable 1 is provided with a boss 101, and the aforementioned mounting groove 102 is provided on the boss 101, protruding from the surface of the worktable 1, so as to avoid interference between the worktable 1 and the pressing component 3, and can be distinguished from other structures on the worktable 1. Of course, it is not limited to this, the mounting groove 102 can also be directly provided on the worktable 1, depending on the actual needs.
[0059] It should be noted that this mounting groove 102 may not be provided, and other structures may be used. For example, multiple support blocks may be provided on the workbench 1 to support the circuit board bracket 17.
[0060] In this embodiment, preferably, as follows: Figure 4 and Figure 5 As shown, the circuit board support detection device also includes a limiting component, and there are multiple limiting components, which are arranged sequentially at intervals along the outer periphery of the mounting groove 102, and are used to limit the circuit board support 17.
[0061] As can be seen from the structure described above, multiple positioning components 7 are located on the side of the circuit board bracket 17, which serve to limit the circumferential structure of the circuit board bracket 17 exposed to the mounting groove 102, making the circuit board bracket 17 more stable during the testing process and preventing displacement and other problems.
[0062] In this embodiment, preferably, as follows: Figure 2 As shown, the handle 34 includes a connecting part 341 and a handle part 342 connected to each other to form an L-shaped structure, and the connecting part 341 is rotatably connected to the first support member 2 and the adapter member 33 respectively.
[0063] As can be seen from the structure described above, the connecting part 341 serves to connect with the first support member 2 and the adapter member 33; the handle part 342 serves to facilitate the operator's grip and rotation of the handle 34.
[0064] Of course, the structure of the handle 34 is not limited to this and can be designed according to actual needs.
[0065] Furthermore, preferably, the end of the handle portion 342 away from the connecting portion 341 is also provided with anti-slip texture to serve a protective function. Of course, this is not the only option; it can be designed according to actual needs.
[0066] In this embodiment, preferably, as follows: Figure 2 As shown, the pressing component 3 also includes a support base 35, which is disposed on the first support member 2, and the sleeve 31 is fixed to the support base 35. The handle 34 is rotatably connected to the support base 35.
[0067] As can be seen from the structure described above, the support base 35 serves as a transition point, facilitating the installation of the handle 34 and the sleeve 31. Of course, this support base 35 can also be omitted, and the handle 34 and the sleeve 31 can be directly installed on the first support member 2, depending on the actual needs.
[0068] Furthermore, preferably, the support base 35 and the first support member 2 can be detachably connected by bolts, facilitating later maintenance. Of course, this is not the only option; the support base 35 and the first support member 2 can also be an integral structure or connected by welding or other methods, depending on the actual needs.
[0069] In this embodiment, preferably, as follows: Figure 2 As shown, there are two adapter components 33, which are respectively arranged on opposite sides of the handle 34 along a direction perpendicular to the first preset direction.
[0070] As can be seen from the structure described above, the adapter components 33 are provided on opposite sides of the handle 34 to form a symmetrical structure, which makes the handle 34 and the sleeve 31 more stable and coordinated during movement. Of course, it is not limited to this, and the number of adapter components 33 can also be one.
[0071] Furthermore, preferably, the adapter 33 includes a U-shaped body and ear plates respectively connected to opposite sides of the U-shaped body, and the two ear plates are rotatably connected to the side of the handle 34, i.e. the side of the connecting part 341 and the side of the pressing rod 32 respectively. Preferably, the opening of the U-shaped body is arranged facing the handle 34. Of course, the structure of the adapter 33 is not limited to this and can be designed according to actual needs.
[0072] In this embodiment, preferably, as follows: Figure 3 As shown, the second support member 4 includes a first support plate 41, a second support plate 42, and a support column 43. The first support plate 41 and the second support plate 42 are sequentially spaced along a first preset direction, and the support column 43 is supported between the two support plates and fixedly connected to each of the two support plates. The first detection member 5 and the second detection member are both fixed to the second support plate 42, with a portion of the structure of the first detection member 5 and the second detection member extending between the two support plates, and another portion extending below the second support plate. The first support plate 41 is connected to the pressing rod 32. Of course, the structure of the second support member 4 is not limited to this and can be selected according to actual needs.
[0073] In this embodiment, preferably, as follows: Figure 1 As shown, the first detection component 5 is a probe, and the second detection component is a socket 172 structure. Of course, it is not limited to this, and other structures can also be used, as long as they can serve the purpose of connecting the circuit.
[0074] In this embodiment, preferably, as follows: Figure 7 As shown, the circuit board bracket testing device also includes a first electrical connector 8, a second electrical connector 9, a third electrical connector 10, a fourth electrical connector 11, and a master control switch 12; wherein, each indicator light 6 is equipped with a first electrical connector 8, and is electrically connected to the corresponding second detection component through the corresponding first electrical connector 8; each indicator light 6 is equipped with a second electrical connector 9, and can be electrically connected to the second pole of the power supply 18 through the corresponding second electrical connector 9;
[0075] Multiple first detection components 5 are arranged sequentially along a second preset direction. The 2i+1th first detection component 5 is equipped with a third electrical connector 10 and can be electrically connected to the power supply 18 through the corresponding third electrical connector 10, where i is an integer greater than or equal to 0. The 2jth first detection component 5 is equipped with a fourth electrical connector 11 and all the fourth electrical connectors 11 can be electrically connected to the first pole of the power supply 18 through the main control switch 12, where j is an integer greater than 0.
[0076] It should be noted that in this embodiment, i = 0, 1, 2, 3, j = 1, 2, 3, 4, that is, there are a total of 8 first detection components 5, and correspondingly, there are 8 indicator lights 6. The 8 first detection components 5 correspond one-to-one with the 8 indicator lights 6. The 1st, 3rd, 5th, and 7th first detection components 5 are all equipped with a third electrical connector 10, and can be electrically connected to the power supply 18 through the corresponding third electrical connector 10. The 2nd, 4th, and 6th first detection components 5 are all equipped with a fourth electrical connector 11, and all the fourth electrical connectors 11 can be electrically connected to the power supply 18 through the main control switch 12. Correspondingly, the 8 indicator lights 6 are also numbered corresponding to the 8 first detection components 5.
[0077] As described above, the pressing component 3 drives the second support component 4 to simultaneously move the first detection component 5 and the second detection component along the first preset direction toward the battery bracket on the workbench 1. This causes the first detection component 5 to contact the busbar 171 on the battery bracket, and the second detection component to contact the socket 172 on the battery bracket. When the first detection component 5 is in contact with the busbar 171 on the battery bracket, and the second detection component is in contact with the socket 172 on the battery bracket, and when the main control switch 12 is turned off, all indicator lights 6 are lit, indicating that the electrical connection structure on the battery bracket is conductive, proving that the circuit is connected. When any indicator light 6 is not lit, it indicates that the circuit on the battery bracket is not connected, proving that there is a problem with the structure at this location. For example, if the fuse at this location is open, it means that the fuse itself is damaged or there is a problem with the solder joint, which can be further inspected. When the main control switch 12 is turned on... If the first, third, fifth, and seventh indicator lights are on, while the second, fourth, sixth, and eighth indicator lights are off, it indicates that there is no solder bridging on the battery holder. If any of these indicator lights are on, it indicates that there is solder bridging. The location of the bridging can be determined by which indicator light is on. For example, if indicator light 2 is on, it means that there is solder bridging between the electrical connections at positions 1 and 2 on the battery holder, or between the electrical connections at positions 2 and 3, or both. A multimeter can then be used to further examine the two areas, greatly narrowing down the scope of the judgment and improving testing efficiency.
[0078] As can be seen, the circuit board bracket inspection device provided in this application can quickly detect the continuity and solder joint defects of the battery bracket, reducing labor intensity, improving inspection efficiency, saving manpower and material resources, and can be directly judged by the lighting status of indicator light 6, which is more intuitive and not affected by human subjective factors, making the inspection results more accurate.
[0079] It should be noted that the first electrical connector 8, the second electrical connector 9, the third electrical connector 10, and the fourth electrical connector 11 can be wires, metal sheets, or other conductive structures, depending on the actual needs.
[0080] In addition, it should be noted that the circuit board bracket 17 is equipped with a bus 171, a socket 172 and a fuse. The fuse is electrically connected between the bus 171 and the socket 172. The detection here is to check whether there is an open circuit at the fuse. In the adjacent parallel bus 171 circuit, there may be an unexpected electrical connection, that is, the aforementioned solder bridging. For example, when solder bridging occurs at the first position 19 or the second position 20 on the circuit board bracket 17, or when both the first position 19 and the second position 20 are soldered, the second indicator light that was originally not lit will be lit.
[0081] Based on the above, since the circuit board bracket 17 is configured as a socket 172, the second detection component is also configured as a matching socket structure to facilitate electrical connection. Of course, it is not limited to this; the second detection component can also be configured as a detection probe structure, etc., depending on the actual needs.
[0082] Furthermore, preferably, the number of second detection components is four, which are adapted to the four sockets 172, and each second detection component is provided with two metal terminal assemblies, so there are a total of eight metal terminal assemblies, which correspond one-to-one with the eight first detection components and the eight indicator lights.
[0083] In this embodiment, preferably, as follows: Figure 7 As shown, the circuit board support testing device also includes a first bus connector 13, all of the fourth connectors 11 are electrically connected to the first bus connector 13, and the first bus connector 13 can be connected to the first pole of the power supply 18; the master switch 12 is disposed on the first bus connector 13, and is disposed at the end of the fourth connectors 11 closer to the power supply 18.
[0084] As can be seen from the structure described above, the main control switch 12 on the first busbar connector 13 can be used to simultaneously control the lighting and extinguishing of indicator lights 2 on line 2, 4 on line 4, 6 on line 6, and 8 on line 8. Compared with the structure where a switch is set on each line, the structure is simpler, the operation is more convenient, and parts are saved. Of course, it is not limited to this. Instead of setting the first busbar connector 13, each line can be connected to the power supply 18 and equipped with a switch for control. The specific choice depends on the actual needs.
[0085] It should be noted that the first bus connector 13 can be an electric wire, a metal sheet, or other conductive structure, depending on the actual needs.

[0087] The circuit board support testing device also includes a first main electrical connector 15, and both the first bus electrical connector 13 and the second bus electrical connector 14 are electrically connected to the first main electrical connector 15, and the first main electrical connector 15 can be electrically connected to the first pole of the power supply 18.
[0088] As can be seen from the structure described above, multiple lines can converge on the first bus connector 13, and only the first bus connector 13 and the second bus connector 14 need to be connected to the first pole of the power supply 18, simplifying the structure. Of course, the first bus connector 13 and the first main power connector 15 can also be omitted, and each line can be directly connected to the power supply 18, depending on the actual needs.
[0089] It should be noted that the second bus connector 14 and the first main connector 15 can be wires, metal sheets or other conductive structures, depending on the actual needs.

All the second electrical connectors 9 are electrically connected to the second main electrical connector 16, and the second main electrical connector 16 can be electrically connected to the power supply 18.
[0091] As can be seen from the structure described above, multiple lines can converge on the second main electrical connector 16, and only the second main electrical connector 16 needs to be connected to the second pole of the power supply 18, simplifying the structure. Of course, it is not limited to this; the second main electrical connector 16 can also be omitted, and each line can be directly connected to the power supply 18, depending on the actual needs.
[0092] It should be noted that the second main electrical connector 16 can be an electric wire, a metal sheet, or other conductive structure, depending on the actual needs.
[0093] It should be noted that the first pole mentioned above can be the positive pole of power supply 18, and the second pole can be the negative pole of power supply 18. Of course, it is not limited to this. The first pole can be the negative pole of power supply 18, and the second pole can be the positive pole of power supply 18. The specific choice depends on the actual needs.
[0094] In this embodiment, preferably, as follows: Figure 1As shown, multiple indicator lights 6 are all located on the workbench 1, resulting in higher integration, a more regular and orderly arrangement, and easier observation. Of course, this is not the only option; the multiple indicator lights 6 may not be located on the workbench 1, depending on the actual needs.
[0095] In this embodiment, preferably, at least a portion of the structure of the first electrical connector 8, the second electrical connector 9, the third electrical connector 10, the fourth electrical connector 11, the main control switch 12, the first busbar connector 13, the second busbar connector 14, the first main electrical connector 15, and at least a portion of the structure of the second main electrical connector 16 can be arranged on the workbench 1, which results in higher integration and makes the wiring less cluttered. Of course, it is not limited to this and can be designed according to actual needs.
[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
