Description

Technical Field

[0001] The invention relates to the technical field of CCS assemblies, and in particular to a nickel-free sheet CCS assembly and a detection device thereof. Background Art

[0002] CCS assembly, also known as CCS integrated busbar, is a highly integrated battery signal acquisition and management system, mainly composed of signal acquisition components, plastic structural parts, busbars, etc. The signal acquisition component FPC includes the main bare board, connector, NTC, acquisition nickel sheet, etc. The busbar is welded and connected to the positive / negative poles of different battery cells to realize series / parallel connection between battery cells. FPC collects electrical signals at the busbar and then reads the voltage and temperature information of the battery cell. CCS is an important component of the battery pack and is widely used in new energy vehicle power batteries and energy storage fields.

[0003] For example, a Chinese patent with the announcement number CN222506392U discloses a CCS test device, which includes a relatively arranged horizontal workbench and a mounting panel, wherein a profiled material plate capable of sliding to the bottom of the mounting panel is arranged on the horizontal workbench, and a plurality of array-arranged probe mounting holes are arranged on the mounting panel; wherein a driving unit capable of driving the mounting panel to vertically rise and fall relative to the horizontal workbench is arranged above the horizontal workbench; the purpose is to overcome the deficiencies in the prior art and solve the problems of the existing integrated busbar test device in terms of complex debugging, high cost, time-consuming and labor-intensive.

[0004] However, the above test device still has some shortcomings in actual use: 1. First, in the above-mentioned prior art, the CCS to be tested is placed on a horizontal workbench for testing, but its stability is poor, which easily causes deviation and dislocation during the testing process; which in turn leads to deviations in the results of the CCS test, and even worse, the CCS falls off during the testing process due to poor stability.

[0005] 2. In addition, when the detection equipment in this application detects CCS, its detection method is relatively simple and cannot guarantee the authenticity and accuracy of the detection results.

[0006] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing testing devices. Summary of the invention

Detailed implementation manners

[0043] The following is a Figures 1 - 13 further detailed description of the present application.

[0044] The embodiments of the present application disclose a nickel-free CCS assembly and its detection device; this device is mainly applied in the quality detection process after the production of the nickel-free CCS assembly A, and can avoid the following problems in terms of technical effects.

[0045] First, in the prior art, the CCS to be detected is placed on the carrier plate 4 for detection. However, its stability is poor, which easily leads to offset and misalignment of the CCS during the detection process; subsequently, the detection result of the CCS is deviated, and even worse, the CCS falls off during the detection process due to poor stability.

[0046] In addition, when the detection device in this application detects the CCS, the detection method is relatively single, and it is impossible to ensure the authenticity and accuracy of the detection result.

[0047] Therefore, this application proposes a nickel-free CCS assembly and its detection device to solve the above problems.

[0048] First, this application proposes a nickel-free CCS assembly.

[0049] Referring to Figure 2 、 Figure 3 and Figure 4 As shown, a nickel-free CCS assembly, the nickel-free CCS assembly A is composed of an FPC sampling board 10, an FPC sampling direct soldering pad 11, a plastic structural member 12, and a copper-aluminum composite BUSBAR 13.

[0050] The FPC sampling board 10 is arranged on the plastic structural member 12 to protect and limit the FPC sampling board 10. The FPC sampling direct soldering pad 11 is integrally connected to the FPC sampling board 10, and the FPC sampling direct soldering pad 11 is also arranged on the plastic structural member 12.

[0051] The copper-aluminum composite BUSBAR 13 is installed on the plastic structural member 12 at equal intervals, and several plastic structural members 12 are connected to the FPC sampling direct soldering pads 11 on the FPC sampling board 10.

[0052] A connector 14 is arranged on one side of the FPC sampling board 10.

[0053] It should be noted that the nickel-free CCS assembly A is a highly integrated battery signal acquisition and management system.

[0054] The traditional nickel-free CCS assembly A is composed of an FPC component, a plastic structural member 12, and a bus bar. The bus bar is welded to the positive / negative electrode posts of different battery cells to realize series / parallel connection between the battery cells. The FPC component collects the electrical signals at the bus bar, and then reads the voltage and temperature information of the battery cells. The CCS is an important component of the battery pack and is widely used in new energy vehicle power batteries and energy storage and other fields.

[0055] At present, the power battery CCS assembly generally uses a flexible printed circuit board (FPC) with nickel sheets for sampling. The BUSBAR material is generally 1060 aluminum in order to achieve laser welding between the aluminum bar and the aluminum cell terminal. The FPC sampling nickel sheet is then laser welded to the aluminum bar to realize the signal transmission path of the cell terminal - aluminum bar - nickel sheet - FPC copper wire loop. This application form of the FPC component requires an additional reflow soldering process to weld each sampling nickel sheet, resulting in more processes and higher costs.

[0056] However, the nickel - free CCS assembly A of this application adopts a nickel - free design, that is, the nickel - free CCS assembly A no longer integrates sampling nickel sheets. Instead, pads are reserved on the sampling circuit (copper substrate). At the same time, the original CCS aluminum bar uses a copper - aluminum composite BUSBAR13, that is, the area in contact with the FPC pad uses T2 copper, and the area in contact with the aluminum cell terminal uses Al1060 aluminum. Thus, it can be ensured that both the bar - terminal and FPC - bar connections can be made by the original laser welding method without adding new equipment. The welding of sampling points can be achieved through the original CCS laser welding equipment, canceling the reflow soldering and related processes of the original FPC sampling nickel sheet, and improving production efficiency.

[0057] By designing the nickel - free CCS assembly A, the welding nickel sheet on the original FPC can be removed by using the copper - aluminum composite BUSBAR13, and the sampling pads on the FPC copper substrate can be directly laser welded to the copper - aluminum composite BUSBAR13. Moreover, this change does not require new CCS production line equipment and can be achieved by simply debugging the original laser welding equipment, simplifying the FPC production process and improving production efficiency. Embodiment 1

[0058] This application also provides a detection device for the nickel - free CCS assembly, which is used to detect the quality of the nickel - free CCS assembly A after production through the nickel - free CCS assembly A detection device; refer to Figure 1 and Figure 5 As shown, the nickel - free CCS assembly A detection device includes a detection box 2 and an opening - closing cover plate 3 hinged to the upper end of the detection box 2.

[0059] A support plate 4 for placing the nickel - free CCS assembly A is slidably installed on the detection box 2, and a number of installation grooves 40 for the plastic structural parts 12 to contact are provided on the support plate 4.

[0060] A number of energizing components 5 for contacting the connectors 14 on the nickel - free CCS assembly A are provided on the opening - closing cover plate 3.

[0061] During specific implementation, when it is necessary to detect the nickel-free sheeted CCS assembly A, first randomly select several nickel-free sheeted CCS assemblies A from the batch-produced nickel-free sheeted CCS assemblies A, then place them on the supporting plate 4 inside the detection box 2, and then the power-on component 5 can be used to conduct a power-on test on them. And during the power-on test, vibration is applied to detect the firmness of the welding of the nickel-free sheeted CCS assembly A.

[0062] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, it is a schematic structural diagram for realizing the telescoping of the supporting plate 4 during the process of opening and closing the opening and closing cover plate 3 in this application; specifically, two groups of detection wheels 20 are rotatably provided in the width direction of the detection box 2, and a control belt 21 for controlling the movement of the supporting plate 4 is sleeved on the two groups of detection wheels 20. One end of the control belt 21 close to the side wall of the detection box 2 is provided with a connecting rod 22, and the connecting rod 22 slidably passes through the detection box 2 and is connected to the supporting plate 4 provided at the upper end of the detection box 2.

[0063] At the hinge joint between the opening and closing cover plate 3 and the detection box 2, there is a hinge gear 23. When the opening and closing cover plate 3 is opened radially, the hinge gear 23 rotates synchronously. A linkage gear 24 is installed on one side of the detection wheel 20, and the linkage gear 24 meshes with the hinge gear 23 to realize the linkage between the opening and closing cover plate 3 and the control belt 21.

[0064] It should be noted that; in the initial state, the supporting plate 4 retracts inside the detection box 2, and the installation groove 40 on the supporting plate 4 is in an exposed state. Further, in the initial state, the opening and closing cover plate 3 is in a closed state.

[0065] In addition, it should be noted that there is an assisting air cylinder hinged between the opening and closing cover plate 3 and the detection box 2, which can ensure that the opening and closing cover plate 3 always moves at a constant speed when opening and closing, and when the opening and closing cover plate 3 is opened, it has a thrust on it to make it fixed, reducing the risk of accidental automatic closing of the opening and closing cover plate 3.

[0066] During specific implementation, when detecting the nickel-free sheeted CCS assembly A, hold the handle on the opening and closing cover plate 3, and control the opening and closing cover plate 3 to rotate upward to open it. During the opening process of the opening and closing cover plate 3, the articulated gear 23 connected to its upper end is driven to rotate. There is an interlocking gear 24 meshing with the articulated gear 23. While the interlocking gear 24 rotates, it drives the detection wheel 20 to rotate. While the detection wheel 20 rotates, it drives the control belt 21 to rotate counterclockwise. The supporting plate 4 connected by the connecting rod 22 at the lower half of the control belt 21 will move away from the detection box 2 following the rotation of the control belt 21 until the supporting plate 4 extends outwards. This can not only ensure that the supporting plate 4 is close to the installation groove 40 inside the detection box 2 for easy placement of the nickel-free sheeted CCS assembly A, but also prevent the opening and closing cover plate 3 from accidentally closing in the open and closed states, resulting in injury to personnel.

[0067] Furthermore, when placing the nickel-free sheeted CCS assembly A, only need to pay attention to the position of the connector 14 of the nickel-free sheeted CCS assembly A, and make the direction of the connector 14 of the nickel-free sheeted CCS assembly A meet the specified requirements. If the nickel-free sheeted CCS assembly A and the supporting plate 4 are in an inclined state, the subsequent automatic limiting component 6 can correct its position, so that it can be horizontally limited on the supporting plate 4 to ensure the stability of the nickel-free sheeted CCS assembly A.

[0068] Refer to Figure 6 、 Figure 7 and Figure 8 As shown in

[0069] Specifically, the detection box 2 is also provided with an automatic limiting component 6 for limiting the FPC sampling board 10 and the plastic structural part 12 on the opening and closing cover plate 3. The automatic limiting component 6 includes two groups of symmetric horizontal adjusting rods 60 arranged along the length direction on the opening and closing cover plate 3 and two groups of symmetric vertical adjusting rods 61 arranged along the width direction on the opening and closing cover plate 3. The horizontal adjusting rods 60 are slidably arranged at the bottom of the opening and closing cover plate 3, and the vertical adjusting rods 61 abut against the upper ends of the horizontal adjusting rods 60.

[0070] Therefore, the four sides of the nickel-free CCS assembly A are surrounded and clamped by the horizontal adjustment rod 60 and the vertical adjustment rod 61, thereby ensuring that the nickel-free CCS assembly A is clamped stably.

[0071] When the nickel-free CCS assembly A is placed on the supporting plate 4, if the nickel-free CCS assembly A is in a tilted state, the horizontal adjustment rod 60 and the vertical adjustment rod 61 can adjust the position of the nickel-free CCS assembly A during the clamping process to ensure the stability of the nickel-free CCS assembly A.

[0072] See also Figure 5 As shown, the detection box 2 is provided with a strip-shaped slide groove 25, in which a fixing block 26 is slidably installed, and the fixing block 26 is connected to a connecting shaft 74 connected to a control gear 75. The purpose is to ensure the stability of the support plate 4 when it is extended and retracted.

[0073] See also Figure 7 , Figure 8 and Figure 9 As shown, it is a schematic diagram of the structure for controlling the movement of the horizontal adjustment rod 60 and the vertical adjustment rod 61 in the present application; a linkage kit 7 is provided between the horizontal adjustment rod 60, the vertical adjustment rod 61 and the opening and closing cover plate 3, and the linkage kit 7 includes a No. 1 bidirectional threaded shaft 70 rotatably installed through a bracket along the length direction of the opening and closing cover plate 3 and a No. 2 bidirectional threaded shaft 71 rotatably installed through a bracket along the width direction of the opening and closing cover plate 3, and a linkage bevel gear 72 is installed on the same side of the No. 1 bidirectional threaded shaft 70 and the No. 2 bidirectional threaded shaft 71, and the two linkage bevel gears 72 are meshed with each other.

[0074] It should be noted that there are two sets of symmetrically distributed threaded structures on the No. 1 bidirectional threaded shaft 70, and two horizontal adjustment rods 60 are screwed on the two sets of threaded structures, and the two horizontal adjustment rods 60 on each set of threaded structures are far away from each other in the initial state; the structure of one of the two No. 2 bidirectional threaded shafts 71 is the same as that of the No. 1 bidirectional threaded shaft 70, and the two vertical adjustment rods 61 of each set of threaded structures on the No. 2 bidirectional threaded shaft 71 are far away from each other in the initial state, at this time, the area of ​​the rectangular processing area formed by the horizontal adjustment rods 60 and the vertical adjustment rods 61 is the largest, which is convenient for placing the nickel-free CCS assembly A inside it. The other No. 2 bidirectional threaded shaft 71 is a smooth guide structure, which only guides the vertical adjustment rod 61 set at its upper end.

[0075] On the linkage bevel gear 72 of the first bidirectional threaded shaft 70, a control bevel gear 73 is engaged. On the back side of the control bevel gear 73, a control gear 75 is installed through a connecting shaft 74. An arc-shaped rack 76 is engaged with the control gear 75. The arc-shaped rack 76 slidably penetrates through the detection box 2, and an arc-shaped groove 77 for the arc-shaped rack 76 to slide is opened in the detection box 2. A lifting tension spring 78 for lifting the arc-shaped rack 76 is arranged in the arc-shaped groove 77.

[0076] It should be noted that in the initial state, the arc-shaped rack 76 and the control gear 75 are engaged with each other. When the supporting plate 4 moves outwards, the control gear 75 moves outwards synchronously with the supporting plate 4. At this time, the arc-shaped rack 76 is separated from it; when the supporting plate 4 completes the installation of the nickel-free CCS assembly A and returns to the inside of the detection box 2, the arc-shaped rack 76 and the control gear 75 are re-engaged.

[0077] During specific implementation, when the nickel-free CCS assembly A is placed on the rectangular processing area of the supporting plate 4 and covers the installation groove 40 of the supporting plate 4, the opening and closing cover plate 3 starts to be closed. When the opening and closing cover plate 3 rotates, it drives the supporting plate 4 to retract to a specified position inside the detection box 2; then the opening and closing cover plate 3 continues to be closed. At this time, the opening and closing cover plate 3 will contact the arc-shaped rack 76 and press down on the arc-shaped rack 76. After the arc-shaped rack 76 receives the downward pressure, it starts to contract into the arc-shaped groove 77 inside the detection box 2. At this time, the arc-shaped rack 76 drives the engaged control gear 75 to rotate. The control gear 75 drives the first bidirectional threaded shaft 70 and the second bidirectional threaded shaft 71 to rotate through the engaged control bevel gear 73; while the first bidirectional threaded shaft 70 and the second bidirectional threaded shaft 71 are rotating, a plurality of horizontal adjusting rods 60 and vertical adjusting rods 61 engaged with their upper ends clamp the nickel-free CCS assembly A.

[0078] After the nickel-free CCS assembly A is clamped, the opening and closing cover plate 3 is just completely closed. At this time, the nickel-free CCS assembly A inside it can be powered on for detection, which is specifically as follows: Refer to Figure 10 As shown, specifically, the power-on component 5 includes a plurality of telescopic spring rods 50 installed on the opening and closing cover plate 3. At the end of the telescopic spring rod 50 far away from the opening and closing cover plate 3, a power-on device 51 for docking with the connector 14 is installed.

[0079] The opening and closing cover plate 3 is connected with a power-on device 51 through a telescopic spring rod 50. The power-on device 51 is a known structure. There is an external power source on the power-on device 51, and there is a power-on component 5 on the power-on device 51 that makes contact with the connector 14 of the nickel-free CCS assembly A. The nickel-free CCS assembly A can be powered on through the connector 14. After the nickel-free CCS assembly A is powered on, the signals of each component at its upper end can be read to detect whether there is a short circuit or an open circuit.

[0080] However, only powering it on for detection makes the detection of the nickel-free CCS assembly A relatively single, and it cannot ensure the overall quality and stability of the entire nickel-free CCS assembly A. Therefore, the present application proposes a vibration component 8, which is specifically as follows: Refer to Figure 10 and Figure 11 As shown, below the supporting plate 4 inside the detection box 2, there is a vibration component 8. The vibration component 8 includes a number of vibration shafts 80 rotatably installed inside the detection box 2. On the vibration shafts 80, there are a number of knocking cams 81 that knock on a number of FPC sampling plates 10 at equal intervals. A synchronous belt 82 is sleeved on the common shaft of the number of vibration shafts 80. On one side of the vibration shaft 80, there is a vibration motor 83, and the vibration motor 83 is arranged on the outer wall of the detection box 2 through a motor seat.

[0081] During specific implementation, when the power-on component 5 conducts power-on detection on the nickel-free CCS assembly A, the vibration motor 83 starts. The vibration motor 83 drives the vibration shafts 80 to rotate at a constant speed. The knocking cams 81 on the vibration shafts 80 rotate synchronously. And while the knocking cams 81 rotate, they quickly knock on the nickel-free CCS assembly A, causing the nickel-free CCS assembly A to vibrate. During the vibrating state, power-on detection is performed on the nickel-free CCS assembly A to detect whether it is damaged or broken within a certain period of time. Embodiment 2

[0082] Refer to Figure 11 、 Figure 12 and Figure 13 As shown, on the basis of Embodiment 1, in order to further improve the detection efficiency and authenticity of the nickel-free CCS assembly A, and ensure that after the nickel-free CCS assembly A is produced, the detection can be completed quickly and its quality can strictly meet the requirements, the present application proposes a linkage detection component 9. Specifically, on the opening and closing cover plate 3, there is also a linkage detection component 9 for detecting the connection firmness of the CCS assembly. The linkage detection component 9 includes a number of bidirectional threaded rods 90 rotatably installed on the opening and closing cover plate 3, and a detection block 91 is screwed on the bidirectional threaded rods 90.

[0083] On the bidirectional threaded rod 90, there is a first gear 92 installed, and on the vibration shaft 80, there is a second gear 93 installed. The first gear 92 and the second gear 93 are meshed with each other.

[0084] When the knocking cam 81 knocks on the bottom of the nickel-free CCS assembly A, the vibration shaft 80 on the knocking cam 81 will also drive the second gear 93 to rotate. The second gear 93 drives the bidirectional threaded rod 90 to rotate through the first gear 92. When the bidirectional threaded rod 90 rotates, it drives the detection block 91 at its upper end to move reciprocally. While the detection block 91 moves reciprocally, the detection rod 96 provided at its upper end scratches the welded position between the copper-aluminum composite BUSBAR 13 and the FPC sampling direct soldering pad 11 in the nickel-free CCS assembly A. The firmness of the welding between the two is detected by reciprocating scratching. If the two come off due to the scratching of the detection rod 96, the energized component 5 can quickly detect it and give an early warning.

[0085] The detection block 91 is of a hollow structure, and four groups of switching rollers 94 distributed in a rectangle are installed in the detection block 91. A switching belt 95 is sleeved on a number of the switching rollers 94. A number of detection rods 96 with different sizes and shapes are equidistantly arranged on the switching belt 95. A switching motor 97 is provided on one side of the switching rollers 94.

[0086] However, it should be noted that multiple detection rods 96 with different sizes and hardnesses are provided in the detection block 91 of the present application. The copper-aluminum composite BUSBAR 13 and the FPC sampling direct soldering pad 11 are scratched by the detection rods 96 with different sizes and hardnesses. The detection rods 96 with different sizes and hardnesses can simulate the scratching conditions in a variety of actual use environments, so as to more comprehensively evaluate the wear resistance and scratch resistance of the CCS assembly.

[0087] Furthermore, by adjusting the shape, material and pressure of the scratching head at the end of the detection rod 96, specific scratching behaviors can be accurately simulated, thus providing a more scientific evaluation basis for the material. The scratching test can not only evaluate the degree of surface damage, but also reveal key performance indicators such as the adhesion and peel strength of the coating or substrate system.

[0088] During specific implementation, when it is necessary to switch the detection rods 96 with different sizes and hardnesses, the switching motor 97 is started. The switching motor 97 controls the switching belt 95 to rotate along the detection block 91, so as to adjust the positions of multiple groups of detection rods 96 with different sizes and hardnesses provided on the switching belt 95, so that the required detection rod 96 can be moved to the designated position.

[0089] During operation: In the first step, when it is necessary to detect the nickel-free CCS assembly A, first randomly select a number of nickel-free CCS assemblies A from the batch-produced nickel-free CCS assemblies A.

[0090] Step 2: Then hold the handle on the opening and closing cover plate 3 and control the opening and closing cover plate 3 to rotate upward to open it. During the opening process of the opening and closing cover plate 3, the control belt 21 rotates counterclockwise, and the support plate 4 connected by the connecting rod 22 at the lower half of the control belt 21 will move away from the detection box 2 following the rotation of the control belt 21 until the support plate 4 extends outward.

[0091] Step 3: After the support plate 4 extends outward, place the nickel-free CCS assembly A on the installation groove 40 of the support plate 4 and cover the installation groove 40. At this time, the nickel-free CCS assembly A is located within the rectangular processing area formed by the horizontal adjustment rod 60 and the vertical adjustment rod 61.

[0092] Step 4: Subsequently, close the opening and closing cover plate 3. When the opening and closing cover plate 3 rotates, it drives the support plate 4 to retract to a specified position inside the detection box 2. At this time, the first bidirectional threaded shaft 70 and the second bidirectional threaded shaft 71 rotate to control the horizontal adjustment rod 60 and the vertical adjustment rod 61 to approach the nickel-free CCS assembly A until the nickel-free CCS assembly A is clamped. At the same time, the position of the nickel-free CCS assembly A is adjusted to be parallel to the support plate 4.

[0093] Step 5: After the opening and closing cover plate 3 is completely closed, the energizer 51 is connected to the connector 14 of the nickel-free CCS assembly A, and the energizer 51 reads the signals of each component at its upper end to detect whether there is a short circuit or an open circuit.

[0094] Step 6: When the power-on component 5 conducts a power-on test on the nickel-free CCS assembly A, the vibration motor 83 starts. The vibration motor 83 drives the vibration shaft 80 to rotate at a constant speed, and the knocking cam 81 on the vibration shaft 80 rotates synchronously. While the knocking cam 81 rotates, it quickly knocks on the nickel-free CCS assembly A, causing the nickel-free CCS assembly A to vibrate. The power-on test of the nickel-free CCS assembly A is carried out in a vibrating state to detect whether it is damaged or broken within a certain period of time.

[0095] Step 7: When the knocking cam 81 knocks on the bottom of the nickel-free CCS assembly A, the bidirectional threaded rod 90 controls the detection block 91 to move reciprocally. While the detection block 91 moves reciprocally, the detection rod 96 provided at its upper end scratches the welded position between the copper-aluminum composite BUSBAR 13 and the FPC sampling direct soldering pad 11 in the nickel-free CCS assembly A. The firmness of the welding between the two is detected through reciprocating scratching. If the two fall off due to the scratching of the detection rod 96, the power-on component 5 can quickly detect it and perform a warning process.

[0096] Step 8: When it is necessary to switch the test rods 96 of different sizes and hardnesses, start the switching motor 97. The switching motor 97 controls the switching belt 95 to rotate along the test block 91, so as to adjust the positions of multiple groups of test rods 96 of different sizes and hardnesses arranged on the switching belt 95, so that the required test rod 96 can be moved to the specified position.

[0097] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
