Description

Technical Field

[0001] This application relates to the field of battery assembly equipment technology, and in particular to a battery module wiring harness assembly equipment and a battery assembly production line. Background Technology

[0002] In the current era of rapid development in the new energy vehicle industry, power battery modules, as the core power source for new energy vehicles, directly determine the overall competitiveness of the industry through their production efficiency and product quality, and are a key factor influencing the industry's large-scale development. In the assembly process of power battery modules, the wiring harness (nickel bar) connection process occupies a central position. The quality of this process not only plays a decisive role in the conductivity of the power battery module, directly affecting its energy transmission efficiency, but is also closely related to the overall structural stability of the module, thus impacting the safety performance of new energy vehicles during operation. Therefore, the reliability and efficiency of the wiring harness connection process are of paramount importance.

[0003] However, the current assembly of power battery module wiring harnesses still mainly relies on manual operation. The specific process is as follows: workers manually retrieve and place the wiring harness (nickel bars) from the storage area, and then use handheld spot welding equipment to weld and fix the wiring harness to the designated position on the battery module. This traditional manual assembly method has two significant problems, which seriously restrict the production efficiency and product quality of power battery modules, making it difficult to meet the large-scale, high-quality production demands brought about by the rapid expansion of the new energy vehicle market. On the one hand, manual operation has inherent limitations in speed. The process of workers retrieving and placing wiring harnesses, adjusting welding positions, and operating spot welding equipment all consume a lot of time, and continuous, uninterrupted, and efficient operation cannot be achieved, resulting in low overall assembly efficiency and becoming a key bottleneck restricting the increase in power battery module production capacity. On the other hand, manual operation is highly susceptible to interference from human factors. For example, workers may become fatigued after working for a long time, which may lead to operational errors such as positional deviations when retrieving and placing wiring harnesses, improper pressure control during welding, or inaccurate welding time. These errors will directly cause inconsistent wiring harness welding quality, and some welding points may have problems such as incomplete welding, missing welding, or insufficient welding strength. Defects in welding quality not only affect the conductivity of the battery module, leading to unstable current transmission and reduced performance, but may also cause safety hazards such as short circuits and overheating due to weld point detachment or poor contact during long-term use, posing a serious threat to the driving safety of new energy vehicles. Summary of the Invention

[0004] The purpose of this application is to provide a battery module wiring harness assembly equipment and a battery assembly production line, so as to solve to a certain extent the technical problem that the manual assembly method in the prior art seriously restricts the production efficiency and product quality of power battery modules, and makes it difficult to meet the large-scale and high-quality production needs brought about by the rapid expansion of the new energy vehicle market.

[0016] Preferably, the gripping member includes two adsorption members, which are spaced apart on the mounting block along the first direction, and the welding part is disposed between the two adsorption members.

[0025] According to a second aspect of this application, a battery assembly production line is provided, including the battery module wiring harness assembly equipment described in any of the above technical solutions, and thus possesses all the beneficial technical effects of the battery module wiring harness assembly equipment, which will not be repeated here.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] The battery module wiring harness assembly equipment provided in this application, on the one hand, uses a first and second conveying component to replace manual handling of battery modules and station switching, as well as manual picking and placing of wiring harnesses, through automated conveying. This not only effectively improves the loading efficiency of battery modules and wiring harnesses to be assembled, but also effectively avoids collisions and misalignments during loading, laying the foundation for the accuracy of subsequent wiring harness welding. On the other hand, the drive unit provides stable and controllable power to the gripping unit, driving it to pick up the wiring harness to be assembled from the previous station and accurately transfer it to the predetermined position of the battery module in the welding station. This replaces the manual picking and positioning of the wiring harness. Because the power output of the drive unit has the characteristic of precise control, it can avoid the deviation in the gripping position of the wiring harness caused by hand tremors and visual judgment errors during manual picking, ensuring that the wiring harness can be accurately placed in the predetermined welding position of the battery module, significantly improving the accuracy of wiring harness positioning, and providing a prerequisite for the stability of subsequent welding quality. Furthermore, the welding section is fixedly located within the gripping section. This allows the gripping section to precisely position the wire harness at the predetermined location, eliminating the need for further adjustments to the welding equipment or manual operation. The welding process can be directly completed between the wire harness and the battery module. This avoids the instability caused by manual hand-held welding, which leads to inconsistent welding quality. The welding parameters can be precisely set and stably executed via a program, ensuring consistent quality at each welding point. This effectively solves the problem of inconsistent quality in existing manual welding, thereby improving the conductivity of the battery module and reducing safety hazards. On the other hand, the integrated gripping and welding operation eliminates the time spent manually adjusting the welding equipment and aligning the welding position, achieving continuous automated operation of wire harness gripping, positioning, and welding. This significantly shortens the assembly time for a single wire harness assembly, further improving overall assembly efficiency. Through the coordinated operation of the first and second transmission components and the gripping and welding components, the problems of low efficiency and unstable quality in existing manual assembly are comprehensively solved. This significantly improves the efficiency, accuracy, and quality stability of power battery module wire harness assembly, while reducing safety hazards and meeting the large-scale, high-quality production needs of the new energy vehicle industry.

[0042] The following reference Figures 1 to 5 This application describes a battery module 6 wiring harness assembly equipment and a battery assembly production line according to some embodiments thereof.

[0043] See Figures 1 to 5 As shown, an embodiment of the first aspect of this application provides a battery module 6 wiring harness assembly device, which includes a first transmission component, a second transmission component, and a gripping and welding component. The first transmission component 1 is used to transfer the battery module 6 into and out of the welding station. The second transmission component 2 is used to transfer the wiring harness 7 to be assembled to the loading station. The gripping and welding component includes a driving part, a gripping part 32, and a welding part 33. The driving part is convexly connected to the gripping part 32 to drive the gripping part 32 to grip the wiring harness 7 to be assembled at the loading station to a predetermined position of the battery module 6 in the welding station. The welding part 33 is fixedly disposed on the gripping part 32 to weld the wiring harness 7 to be assembled and the battery module 6 at the predetermined position.

[0044] According to the battery module 6 wiring harness assembly equipment provided by the above-mentioned technical features, on the one hand, the first conveying component 1 and the second conveying component 2 replace manual handling of battery module 6, station switching, and manual picking and placing of wiring harnesses through automated conveying. This not only effectively improves the loading efficiency of battery module 6 and wiring harness 7 to be assembled, but also effectively avoids collisions and offsets between battery module 6 and wiring harness 7 during loading, laying the foundation for the accuracy of subsequent wiring harness welding. On the other hand, the drive unit can provide stable and controllable power to the gripping unit 32, driving the gripping unit 32 to pick up the wiring harness 7 to be assembled from the previous station and accurately transfer it to the predetermined position of battery module 6 in the welding station. This replaces the manual picking and positioning of wiring harnesses. Because the power output of the drive unit has the characteristic of precise control, it can avoid the deviation in the gripping position of wiring harnesses caused by hand tremors and visual judgment errors during manual picking, ensuring that the wiring harness can be accurately placed in the predetermined welding position of battery module 6, significantly improving the accuracy of wiring harness positioning, and providing a prerequisite for the stability of subsequent welding quality. In addition, the welding part 33 is fixedly installed on the gripping part 32, so that after the gripping part 32 accurately positions the wire harness to the predetermined position, there is no need to adjust the position of the welding equipment or manually operate the welding equipment. The welding operation between the wire harness and the battery module 6 can be completed directly through the welding part 33. On the one hand, it avoids the fluctuation of welding quality caused by the unstable operation of the welding equipment when it is manually operated. The welding parameters of the welding part 33 can be accurately set by the program and executed stably to ensure the consistency of the quality of each welding point. This effectively solves the problem of inconsistent quality of existing manual welding, thereby improving the conductivity of the battery module 6 and reducing safety hazards. On the other hand, the integrated operation of gripping and welding saves the time of manually adjusting the welding equipment and aligning the welding position. It realizes the continuous automated operation of wire harness gripping, positioning and welding, which greatly shortens the operation time of a single wire harness assembly and further improves the overall assembly efficiency. Through the coordinated operation of the first conveying component 1, the second conveying component 2, and the gripping and welding component, the problems of low efficiency and unstable quality in existing manual assembly are comprehensively solved. The efficiency, accuracy, and quality stability of the power battery module 6 harness assembly are significantly improved, while safety hazards are reduced, which can meet the large-scale and high-quality production needs of the new energy vehicle industry.

[0045] Preferably, such as Figures 1 to 3 As shown, the first conveying group has a first conveying plane for conveying the battery module 6, and the second conveying group has a second conveying plane for conveying the wire harness 7 to be assembled. The gripping part 32 can be disposed above both the first and second conveying planes. Figure 1 and Figure 2As shown, the transmission direction of the first transmission component 1 can be a first direction F1, and the transmission direction of the second transmission component 2 can be a second direction F2, with the first direction F1 and the second direction F2 intersecting. Figures 1 to 3 As shown in the figure, F1 can be an example of the first direction F1 mentioned above, and F2 can be an example of the second direction F2 mentioned above. Preferably, the first direction F1 and the second direction F2 can be set perpendicularly, so that the layout of the first transmission component 1 and the second transmission component 2 is more reasonable, thereby reducing the probability of interference between the first transmission component 1 and the second transmission component 2. For ease of description, the direction perpendicular to the plane determined by the first direction F1 and the second direction F2 is defined as the third direction F3. F3 shown in the figure can be an example of the third direction F3 mentioned above. When the battery module 6 wiring harness assembly equipment is in use, the third direction F3 can be parallel to the direction of gravity.

[0046] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned driving unit may include a first driving member 311 and a second driving member 312. The first driving member 311 is arranged along the conveying direction of the second conveying assembly 2. The first driving member 311 is connected to the second driving member 312 in a transmission manner to drive the second driving member 312 to move along the conveying direction of the second conveying assembly 2. The second driving member 312 is connected to the gripping part 32 in a transmission manner to drive the gripping part 32 to move along the first direction F1. In this way, a two-dimensional driving structure of "XY axis" is formed, which replaces manual adjustment and ensures that the gripping part 32 can accurately align with the wire harness at the loading station and can be completely matched with the predetermined position of the battery module 6 when it is transferred to the welding station. This solves the problem of manual positioning deviation and lays the foundation for stable welding quality in the future.

[0047] Optionally, such as Figure 1 and Figure 2 As shown, the second conveying component 2 can be a second conveyor belt that conveys along the second direction F2.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, the first drive unit 311 may include a first electric linear module extending along the second direction F2, and the first drive unit 311 is fixedly disposed on both sides of the second conveyor belt in the first direction F1.

[0049] Preferably, such as Figures 1 to 3As shown, the second drive unit 312 may include a gantry and a second electric linear module. The gantry includes a connecting rod extending along a first direction F1 and two legs extending along a third direction F3. The two legs are respectively connected to the first drive unit 311 on both sides of the second conveyor belt in the first direction F1. The connecting rod connects to the end of the two legs away from the second conveyor belt. The second electric linear module may be fixed to the connecting rod.

[0050] Preferably, such as Figure 1 and Figure 2 As shown, the gripping part 32 can be connected to the second electric linear module via a transmission.

[0051] Preferably, such as Figures 1 to 4 As shown, the gripping part 32 may include a gripping member 323 and a transmission bracket 321. The driving part may also include a third driving member 313. The second driving member 312 is connected to the transmission bracket 321, and the third driving member 313 is disposed on the transmission bracket 321 and is connected to the gripping member 323 to drive the gripping member 323 to move along the third direction F3. In this way, when gripping the wire harness, the gripping member 323 can be accurately lowered to the height of the wire harness, and the gripping force is controlled by mechanical force. On the other hand, when placing the wire harness, the gripping member 323 can be driven to lower to the height of close contact with the surface of the battery module 6, eliminating the gap when manually placed and ensuring full contact between the wire harness and the module during welding.

[0052] Preferably, such as Figure 4 As shown, the transmission bracket 321 may include a bracket body 3210 and a transmission edge 3211 connected to each other. The bracket body 3210 may extend along the second direction F2, and the transmission edge 3211 may be disposed at one end of the bracket body 3210 in the second direction F2. The transmission bracket 321 may be connected to the second electric linear module via the transmission edge 3211.

[0053] Optionally, the aforementioned third driving component 313 can be a linear drive device such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder, for example... Figure 4 As shown, the third driving member 313 can be fixed on the bracket body 3210, and the driving end of the third driving member 313 is connected to the gripping member 323 in a transmission connection.

[0054] Preferably, such as Figure 4As shown, the gripping part 32 may further include an adjusting member 322 and a plurality of gripping members 323. The transmission bracket 321 extends along the second direction F2. The adjusting member 322 is fixedly mounted on the transmission bracket 321. The plurality of gripping members 323 are spaced apart on the adjusting member 322 along the second direction F2, and the adjusting member 322 is connected to the gripping members 323 in a transmission manner to adjust the spacing between two adjacent gripping members 323. Thus, on the one hand, setting multiple gripping members 323 can realize the simultaneous gripping and welding of multiple wire harnesses 7 to be assembled, improving work efficiency; on the other hand, by adjusting the spacing of the gripping members 323 through the adjusting member 322, the gripping part 32 can adapt to battery modules 6 of different sizes and specifications, improving the versatility of the battery module 6 wire harness assembly equipment.

[0055] Preferably, such as Figure 4 As shown, the aforementioned adjusting member 322 may include a mounting frame 3221, a lead screw 3222, and a drive motor 3223. The mounting frame 3221 and the lead screw 3222 may extend along the second direction F2. The drive motor 3223 is connected to the lead screw 3222 in a transmission manner and is fixed on the mounting frame 3221. The aforementioned gripping member 323 may be provided with an internal threaded hole that matches the lead screw 3222. Thus, when the drive motor 3223 drives the lead screw 3222 to rotate, the lead screw 3222 can drive the gripping member 323 to move along the second direction F2 to adjust the spacing between adjacent gripping members 323.

[0056] Optionally, such as Figure 4 As shown in the figure, an example of two grippers 323 is illustrated to accommodate the structure of most battery module 6 cells, which include both positive and negative electrodes. Optionally, the threads of the internal threaded holes of the two grippers 323 can be oriented in opposite directions. Thus, when the drive motor 3223 drives the lead screw 3222 to rotate, the two grippers 323 can move towards or away from each other, thereby adjusting the distance between the two grippers 323.

[0057] Preferably, such as Figure 4 As shown, the adjusting member 322 may further include a second guide rod 3224 extending along the second direction F2. The second guide rod 3224 may be arranged side by side with the lead screw 3222 and may be fixed to the mounting frame 3221. The gripping member 323 may be slidably connected to the second guide rod 3224 so as to improve the stability and accuracy of the gripping member 323 moving along the second direction F2 through the guiding effect of the second guide rod 3224.

[0058] Preferably, such as Figure 4As shown, the adjustment member 322 may also include a guide fixing piece 3225, which is fixedly connected to the mounting frame 3221. The second guide rod 3224 passes through the guide fixing piece 3225 along the second direction F2 to improve the stability of the second guide rod 3224.

[0059] Preferably, such as Figure 4 As shown, the transmission bracket 321 may further include a first guide rod 3212 extending along the third direction F3. The first guide rod 3212 passes through the bracket body 3210 and is slidably connected to both the bracket body 3210 and the first guide rod 3212. One end of the first guide rod 3212 is fixedly connected to the mounting frame 3221. Through the guiding effect of the first guide rod 3212 and the bracket body 3210, the stability and accuracy of the gripper 323 moving along the third direction F3 are improved.

[0060] Preferably, such as Figure 4 As shown in the figure, an example of two first guide rods 3212 is illustrated. The two first guide rods 3212 are spaced apart along the second direction F2 on the bracket body 3210 to further improve the stability and accuracy of the gripper 323 moving along the third direction F3. However, this is not the only limitation. The number of first guide rods 3212 is not limited to the example of two. The number of first guide rods 3212 can be adaptively adjusted according to the dimensions of the mounting frame 3221 and the bracket body 3210 in the second direction F2. For example, the number of first guide rods 3212 can also be one, three, or more.

[0061] Preferably, such as Figure 4 and Figure 5 As shown, the gripper 323 may include a mounting block 3231 and an adsorption component. The mounting block 3231 is connected to the adjusting component 322. The adsorption component is located on the side of the mounting block 3231 opposite to the adjusting component 322 and is used to adsorb the wire harness 7 to be assembled. In this way, the adsorption component adsorbs the wire harness by negative pressure. The adsorption gripping has no mechanical clamping force, which can avoid deformation of the nickel bar and ensure the original conductivity of the wire harness.

[0062] Preferably, such as Figure 4 and Figure 5 As shown, the cross-sectional shape of the aforementioned mounting block 3231 can be an inverted T-shape, which ensures that there is enough space on the bottom surface of the mounting block 3231 to arrange the adsorption component and the welding part 33 described below, while effectively saving the material of the mounting block 3231 and reducing the weight of the mounting block 3231.

[0063] Preferably, such as Figure 4 and Figure 5As shown, the welding part 33 can be fixed to the side of the mounting block 3231 opposite to the adjusting member 322. In this way, the welding part 33 and the adsorption member are placed on the same side of the mounting block 3231. After the gripping member 323 places the wire harness in place, the welding part 33 can start welding immediately without repositioning the welding gun, which further improves the overall efficiency.

[0064] Preferably, such as Figure 4 and Figure 5 As shown, the gripper 323 may include two adsorption members, which are spaced apart on the placement block 3231 along the first direction F1. The welding part 33 may be disposed between the two adsorption members. In this way, the two adsorption members adsorb the wire harness at intervals along the first direction F1, forming a "two-point fixation" so that the wire harness does not shake when it is moved. At the same time, the welding part 33 is located in the middle of the two adsorption members, which is exactly aligned with the core position of the wire harness welding, further improving the stability of the welding part 33 in the welding process.

[0065] Alternatively, the welding part 33 may be an electric welding head.

[0066] Preferably, such as Figure 4 and Figure 5 As shown, the aforementioned adsorption component may include an air suction pipe 3232, a suction cup 3233, and a return spring 3234. The suction cup 3233 is disposed at one end of the air suction pipe 3232 and communicates with the air suction pipe 3232. The air suction pipe 3232 is fixedly connected to the mounting block 3231, and the air suction pipe 3232 passes through the mounting block 3231 in a third direction F3. The return spring 3234 is sleeved on the outside of the air suction pipe 3232 and press-fitted between the suction cup 3233 and the mounting block 3231. Thus, on the one hand, the suction cup 3233 communicates with the air suction pipe 3232, and air is drawn in. The tube 3232 is connected to a negative pressure device (such as an air pump or air compressor) so that the adsorption component can provide a continuous and stable negative pressure to the wire harness 7 to be assembled, thereby making the suction cup 3233 fit more tightly to the surface of the wire harness and reducing the risk of the wire harness 7 falling off. On the other hand, by setting a reset spring 3234, the pressure of the suction cup 3233 when it contacts can be buffered. When the suction cup 3233 contacts the wire harness / module, the spring is compressed to absorb the impact force, avoiding damage caused by rigid contact, while ensuring that the suction cup 3233 always fits the surface (compensating for minor planar errors).

[0067] In an embodiment, preferably, such as Figures 1 to 3 As shown, the first conveying component 1 may include a first conveyor belt 11, which is used to convey the battery module 6, wherein, as Figure 3 As shown, the first conveyor belt 11 may include a conveying layer 111 (i.e., the upper layer of the first conveyor belt 11) and a return layer 112 (the lower layer of the first conveyor belt 11) that are connected end to end.

[0068] Preferably, such as Figure 3As shown, the first conveying component 1 may further include a reinforcing support roller 13, which is disposed at the welding station and passes between the conveying layer 111 and the return layer 112. In this way, the reinforcing support roller 13 can provide rigid support for the battery module 6 at the welding station, effectively preventing the battery module 6 from shaking during welding, ensuring the stability of the welding point position, and solving the problem of welding deviation caused by vibration.

[0069] Preferably, such as Figure 1 and Figure 2 As shown, the first conveying component 1 may further include a centering section 12. In the conveying direction of the first conveyor belt 11, the centering section 12 is located on the upstream side of the welding station. The centering section 12 includes two driving push blocks arranged opposite to each other. The two driving push blocks are located on both sides of the first conveyor belt 11, and the two driving push blocks can move closer to each other and further away from each other. In this way, before the battery module 6 enters the welding station, the two driving push blocks can move closer to each other to push the battery module 6 to be centered and provide a precise reference for subsequent wire harness welding.

[0070] Preferably, such as Figure 1 and Figure 2 As shown, the aforementioned drive push block may include a guide plate 121, a fixed plate 122, and an electric push rod 123. The fixed plate 122 may be fixedly mounted on the frame on one side of the first conveyor belt 11 in the second direction F2. The guide plate 121 is mounted on the first conveyor belt 11, and the electric push rod 123 is connected to the fixed plate 122 and the guide plate 121 in a transmission manner, so that the guide plate 121 can be moved along the second direction F2 by the extension and retraction of the electric push rod 123.

[0071] Preferably, such as Figure 1 and Figure 2 As shown, the guide plate 121 may include a guide portion and a positioning portion connected to each other. The positioning portion extends along a first direction F1, and the guide portion is disposed upstream of the positioning portion in the conveying direction of the first conveyor belt 11. In the direction from one end of the guide portion away from the positioning portion to the other end, the guide portion gradually tilts towards the middle of the first conveyor belt 11 to facilitate guiding the battery module 6 into the space between the two drive pushers.

[0072] In an embodiment, preferably, such as Figure 4 and Figure 5As shown, the battery module 6 wiring harness assembly equipment may further include a vision inspection unit 4, which can be used to monitor the position information of the wiring harness 7 to be assembled and the battery module 6. The bracket body 3210 may further include a vision inspection frame 3213, which is fixedly disposed on one side of the bracket body 3210 in the first direction F1 and disposed in the middle of the bracket body 3210. The vision inspection unit 4 can be fixed to the gripping unit 32 via the vision inspection frame 3213. In this way, the vision inspection unit 4 (such as an industrial camera, CCD camera, etc.) can collect position information in real time, quickly identify deviations that are difficult for humans to detect, avoid "poor welding caused by the accumulation of deviations", and solve the "limitations of human visual judgment".

[0073] Preferably, such as Figures 1 to 3 As shown, the battery module 6 wiring harness assembly equipment may further include a control unit 5, which can be communicatively connected to the vision inspection unit 4, the first conveying component 1, and the second conveying component 2, respectively. The control unit 5 adjusts the conveying parameters of the first conveying component 1 and / or the second conveying component 2 according to the position information of the wiring harness 7 and the battery module 6 to be assembled monitored by the vision inspection unit 4. In this way, the control unit 5 automatically adjusts the parameters of the first conveying component 1 and the second conveying component 2 (such as speed, start and stop timing, etc.) according to the vision inspection data, without manual intervention, and can compensate for deviations in real time (such as controlling the first conveyor belt 11 to slightly shift to the left when the battery module 6 is shifted to the right), ensuring that the wiring harness and the battery module 6 are always accurately aligned, and improving the overall assembly stability.

[0074] Optionally, the control unit 5 mentioned above can be a PLC cabinet (Programmable Logic Controller Cabinet), an industrial computer, etc.

[0075] The second aspect of this application also provides a battery assembly production line, including the battery module 6 wiring harness assembly equipment described in any of the above embodiments, and thus has all the beneficial technical effects of the battery module 6 wiring harness assembly equipment, which will not be repeated here.

[0076] 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.
