Description

Technical Field

[0001] This utility model relates to the field of new energy battery technology, and in particular to a patching device and a battery module patching equipment. Background Technology

[0002] The process of integrating multiple battery modules into a larger structure—a battery pack or battery box—is a crucial assembly step in electric vehicles, energy storage systems, and other applications requiring high-capacity batteries. Inside the battery box, liquid cooling plates are typically used for heat dissipation to ensure the battery modules operate within a suitable temperature range. However, it is essential to attach insulating sheets between the liquid cooling plates and the battery modules to ensure the system's electrical safety, mechanical stability, and effective thermal management.

[0003] In existing technologies, most insulating sheets are applied manually, which affects production efficiency and easily leads to uneven bonding force. When the module is long, the excessive bonding distance can cause the edges to lift and become dirty. Long insulating sheets can also be misaligned, affecting the range of excess adhesive and heat conduction efficiency. Utility Model Content

The roller member is used to mount the patch onto the component to be patched. The patch assembly is provided with an isolation groove for isolating the release paper of the patch.

[0007] In one embodiment, the patch assembly includes a limiting member connected to the driving member. The limiting member has a limiting groove for limiting the sheet material, and the limiting member also has an isolation groove.

[0008] In one embodiment, the limiting member includes a top plate and a plurality of side plates. The top plate is connected to the driving member, and the plurality of side plates are connected to the top plate at intervals.

[0010] In one embodiment, the driving component includes a driving handle and a second elastic member. The driving handle and the fixed frame are slidably connected. The end of the driving handle away from the fixed frame is connected to the connecting member. The rolling member is rotatably connected to the side of the connecting member away from the driving handle. The second elastic member is sleeved on the outer periphery of the driving handle and is used to abut against the fixed frame and the connecting member respectively.

[0011] In one embodiment, the isolation groove is provided with locking teeth; or, the isolation groove is provided with adhesive.

[0012] In one embodiment, the patching device includes a positioning component. The positioning component is connected to both ends of the fixing frame along its length. The positioning component includes a limiting rod and a positioning rod. The limiting rod is slidably disposed on the fixing frame along its length, and the positioning rod is slidably disposed on the limiting rod along its width. The positioning rod is used to fix the part to be patched, and the limiting rod is used to limit the part to be patched.

[0013] In one embodiment, the limiting rod is slidably connected to the fixing frame along the length direction of the fixing frame and extends out of the fixing frame along the width direction of the fixing frame.

[0014] In one embodiment, along the width direction of the fixing frame, the length of the limiting rod is L1, and the length of the rolling element is L2, where L1 > L2.

Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] See Figure 1 This application provides a battery module patching device, including a patching device 10, a battery box 20 and an insulating sheet (not shown in the figure). The insulating sheet is disposed inside the battery box 20. The patching device 10 is fixed in a preset installation position in the battery box 20. The patching device 10 is used to attach the insulating sheet tightly to the battery box 20.

[0029] In practical applications, the battery box 20 is equipped with a liquid cooling plate, and an insulating sheet is placed between the liquid cooling plate and the battery module. The insulating sheet can typically be adhered to both sides. One side of the insulating sheet is attached to the liquid cooling plate, and then the mounting device 10 uses rolling to evenly press the insulating sheet firmly onto the liquid cooling plate. After the insulating sheet is adhered, the release paper on the other side of the insulating sheet is peeled off, and then the battery module is placed inside the battery box 20 and adhered to the other side of the insulating sheet to provide better stability and thermal conductivity.

[0030] See again Figure 1 The aforementioned patch assembly 10 includes a fixing frame 1 and a patch assembly 2. The fixing frame 1 is used to connect the part to be patched (battery box 20). The patch assembly 2 includes a driving member 21 and a rolling member 22. The driving member 21 is slidably connected to the fixing frame 1, and the end of the driving member 21 away from the fixing frame 1 is rotatably connected to the rolling member 22. The rolling member 22 is used to patch the sheet material onto the part to be patched (battery box 20). The patch assembly 2 is provided with an isolation groove 24, which is used to isolate the release paper of the sheet material (insulating sheet).

[0031] To clearly describe the embodiments, Figure 1 In this context, X represents the length direction of the battery box 20 or the mounting bracket 1.

[0032] In the battery module mounting equipment, the component to be mounted can be a battery box 20, and the sheet material is an insulating sheet. The battery box 20 has a pre-installation position, and the fixing frame 1 is installed in the pre-installation position to complete the positioning connection between the fixing frame 1 and the battery box 20. The driving component 21 can slide along the length direction X of the fixing frame 1, which is also the length direction X of the battery box 20. A rolling component 22 is connected to one end of the driving component 21 near the battery box 20. The rolling component 22 is rotatably connected to the driving component 21. When the driving component 21 moves along the length direction X of the fixing frame 1, the rolling component 22 rolls along the length direction X of the insulating sheet to evenly press the insulating sheet, so that the insulating sheet can be stably attached to the liquid cooling plate inside the battery box 20. The rolling component 22 can be a roller or similar structure.

[0033] Furthermore, the patch assembly 2 has an isolation groove 24. Before the rolling element 22 rolls the insulating sheet, the release paper portion of the insulating sheet facing the rolling element 22 can be torn open and passed through the isolation groove 24. Thus, when the driving element 21 drives the rolling element 22 to roll the insulating sheet, the isolation groove 24 moves the release paper, causing relative displacement between it and the insulating sheet, thereby peeling the release paper off the insulating sheet. By passing the release paper through the isolation groove 24 and then moving the isolation groove 24 to peel the release paper, an efficient and stable peeling process can be achieved, suitable for large-scale production and automated production lines, improving production efficiency. This method not only reduces the risks of manual operation but also ensures good adhesion of the insulating sheet, avoiding damage or affecting its performance.

[0034] It should be noted that release paper, also known as release liner, anti-stick paper, or silicone paper, is a type of paper with a specially treated surface. Its main characteristic is its excellent anti-stick properties, which effectively prevent it from sticking to adhesive materials (such as insulating sheets), and it is easy to peel off without leaving any residue. To improve the ease of peeling off the release paper, one end of the release paper passing through the release groove 24 is manually or mechanically fixed. This makes it easier to peel the release paper off the insulating sheet when the release groove 24 moves.

[0035] In one embodiment, the release liner 24 may be provided with locking teeth or adhesive. When the release paper passes through the release liner 24, the locking teeth in the release liner 24 hold the release paper in place, preventing it from falling out of the release liner 24 and thus avoiding affecting the release of the release paper. Alternatively, adhesive or other adhesive may also be provided in the release liner 24 to stick the release paper, which can also prevent the release paper from falling out of the release liner 24.

[0036] See Figure 2 The patch assembly 2 includes a limiting member 23, which is connected to a driving member 21. The limiting member 23 has a limiting groove 233 for limiting the sheet (insulating sheet). The limiting member 23 also has an isolation groove 24.

[0037] To clearly describe the embodiments, Figure 2 In this diagram, X represents the length direction of the fixing frame 1, Y represents the width direction of the fixing frame 1, and Z represents the height direction of the fixing frame 1.

[0038] In practical applications, the limiting member 23 can be arranged sequentially with the rolling member 22 along the length X of the fixed frame 1. For example, along the forward direction of the driving member 21, the limiting member 23 can be located behind the rolling member 22. The limiting member 23 has an isolation groove 24 and a limiting groove 233. The insulating sheet is located in the limiting groove 233, and the release paper passes through the isolation groove 24. When the driving member 21 moves along the length X of the fixed frame 1, the rolling member 22 first rolls the insulating member, and then the limiting member 23 moves. The limiting groove 233 abuts against the insulating sheet along the width Y, correcting the position of the insulating sheet and improving the bonding accuracy of the insulating sheet. This arrangement allows the rolling member 22 to roll first and then correct the position of the insulating sheet. Even if the insulating sheet undergoes slight displacement during the rolling process of the rolling member 22, the limiting member 23 can physically limit and correct it back to the correct position, ensuring that the relative position of the insulating sheet and the battery box 20 is accurate.

[0039] Meanwhile, the limiting member 23 has an isolation groove 24. After the rolling member 22 is rolled, the release paper is peeled off, which can prevent the rolling member 22 from contacting the adhesive surface of the insulating sheet and avoid damaging the adhesive performance of the insulating sheet.

[0040] It should be noted that the positions of the limiting member 23 and the rolling member 22 are not limited. The limiting member 23 can be located in front of the rolling member 22 along the forward direction of the driving member 21, and the insulating sheet can be limited and then rolled along the length direction X; or the limiting member 23 and the rolling member 22 can be arranged sequentially along the height direction Z, and the insulating sheet can be limited and rolled at the same time.

[0041] See Figure 3 The limiting member 23 includes a top plate 231 and multiple side plates 232. The top plate 231 is connected to the driving member 21. The multiple side plates 232 are connected to the top plate 231 at intervals. The top plate 231 has an isolation groove 24. A limiting groove 233 is formed between two adjacent side plates 232. At least one side plate 232 is used to limit the sheet.

[0042] In practical applications, multiple side plates 232 are spaced apart on the top plate 231 along the width direction Y. A limiting groove 233 is formed between two adjacent side plates 232. The insulating sheet can be corrected by the limiting groove 233 or limited by a single side plate 232. For example, if the insulating sheet is attached to the side of the battery box 20, it cannot enter the limiting groove 233 due to the limitation of the side of the battery box 20. In this case, a single side plate 232 can be attached to the side of the insulating sheet away from the side of the battery box 20, and the side and the side of the battery box 20 can be used to correct the position of the insulating sheet. Alternatively, for some narrower insulating sheets, it is more convenient to correct the position by directly limiting the position on one side with a single side plate 232 than to set a limiting groove 233 of corresponding width.

[0043] Meanwhile, an isolation groove 24 is provided on the top plate 231. The top plate 231 is usually set parallel to the insulating sheet. In this way, when the release paper is peeled off, the release paper and the insulating sheet will have a parallel relative displacement, which can avoid the release paper from tearing due to shear force during the peeling process and affecting the peeling effect.

[0044] See again Figure 3 The driving component 21 includes a connector 211, which is slidably connected to the fixing frame 1. The connector 211 has multiple switching slots 2111 along its width direction Y. The patch assembly 2 includes a first elastic member 25. The limiting member 23 includes a supporting part 234, which passes through one of the switching slots 2111 and overlaps with the connector 211. The first elastic member 25 is elastically connected to the supporting part 234 and the connector 211 respectively, so as to press the supporting part 234 against the switching slot 2111.

[0045] In practical applications, the limiting member 23 is inserted into the switching slot 2111 via the abutment part 234 and overlaps with the connector 211, thus fixing the limiting member 23 and preventing it from falling off the drive member 21. Simultaneously, a first elastic member 25 abuts against the abutment part 234 and the connector 211 along the length X of the fixing frame 1. The extension direction of the switching slot 2111 is consistent with the length X of the fixing frame 1. This allows the first elastic member 25 to press the abutment part 234 firmly against the slot wall of the switching slot 2111, improving the connection stability between the limiting member 23 and the connector 211. This prevents the limiting member 23 from moving during the mounting process, thus avoiding misalignment of the insulating sheet and improving the quality of the mounted product to a certain extent. Furthermore, during the mounting process, the limiting member 23 inevitably collides with the battery box 20. The first elastic member 25 can transform the rigid collision into an elastic collision, causing the limiting member 23 to undergo a certain elastic displacement upon impact, thus buffering the impact and preventing damage to the battery box 20.

[0046] To accommodate different insulating sheet placement methods, the connector 211 has multiple switching slots 2111 along the width Y direction of the fixing frame 1. The abutment 234 is positioned within different switching slots 2111, allowing adjustment of the side plate 232's position along the width Y direction, thereby adjusting the relative position of the side plate 232 and the insulating sheet. This facilitates different methods of correcting the insulating sheet. For example, when a single side plate 232 is needed to correct the insulating sheet's position, the abutment 234 is installed on the outermost switching slot 2111, ensuring that only a single side plate 232 contacts the side of the insulating sheet. To facilitate switching of the abutment 234, one side of each of the multiple switching slots 2111 can be interconnected. The first elastic member 25 can be a spring or similar structure.

[0047] See again Figure 3 The driving component 21 includes a driving handle 212 and a second elastic component 213. The driving handle 212 and the fixed frame 1 are slidably connected. A connector 211 is connected to one end of the driving handle 212 away from the fixed frame 1. A rolling component 22 is rotatably connected to the side of the connector 211 away from the driving handle 212. The second elastic component 213 is sleeved on the outer periphery of the driving handle 212 and is used to abut against the fixed frame 1 and the connector 211 respectively.

[0048] In practical applications, the drive handle 212 is slidably connected to the fixed frame 1 along the length direction X and extends out of the fixed frame 1 along the height direction Z. The connector 211 is connected to the end of the drive handle 212 near the insulating sheet, and the rolling element 22 is connected to the end of the connector 211 near the insulating sheet. A second elastic element 213 is sleeved on the outer periphery of the part of the drive handle 212 that extends out of the fixed frame 1. The second elastic element 213 abuts against the connector 211 and the fixed frame 1 respectively. The connector 211 moves relative to the fixed frame 1 along the height direction Z. Therefore, when the rolling element 22 rolls the insulating sheet, due to the opposite force, the connector 211 will have a slight displacement in the direction away from the insulating sheet, causing the second elastic element 213 to be compressed. The elastic effect of the second elastic element 213 pushes the connector 211 closer to the insulating sheet, thereby providing a thrust to the rolling element 22 toward the insulating sheet, so that the rolling element 22 is in close contact with the insulating sheet during operation, thereby making the fit between the insulating sheet and the battery box 20 (liquid cooling plate) tighter and improving the mounting quality.

[0049] Meanwhile, the second elastic element 213 can adjust the force applied by the rolling element to the insulating sheet, so as to avoid the rolling force of the rolling element being too large, which would cause the insulating sheet or battery box 20 to be damaged.

[0050] See Figure 4 The patching device 10 includes a positioning component 3. The positioning component 3 is connected to both ends of the fixing frame 1 along its length direction X. The positioning component 3 includes a limiting rod 31 and a positioning rod 32. The limiting rod 31 is slidably disposed on the fixing frame 1 along the length direction X. The positioning rod 32 is slidably disposed on the limiting rod 31 along the width direction Y of the fixing frame 1. The positioning rod 32 is used to fix the part to be patched, and the limiting rod 31 is used to limit the part to be patched.

[0051] In practical applications, the battery box 20 is usually pre-set with mounting holes. In order to facilitate the positioning of the fixing frame 1, this application provides a positioning component 3. The positioning component 3 is connected to both ends of the fixing frame 1 along the length direction X. During installation, the positioning rod 32 is fixed in the mounting hole to fix the fixing frame 1 and the battery box 20, so as to ensure that the fixing frame 1 is installed in the preset position and to avoid displacement of the fixing frame 1 during the patching process. The positioning rod 32 is slidably set along the width direction Y of the fixing frame 1, and the position of the positioning rod 32 in the width direction Y can be adjusted, thereby adjusting the position of the fixing frame 1 relative to the battery box 20, so as to facilitate the patching of insulating sheets at different positions.

[0052] The positioning component 3 also includes a limiting rod 31, which is set along the length direction X of the fixing frame 1. That is, the limiting rod 31 can move along the length direction X of the fixing frame 1. The positioning rod 32 is connected to the limiting rod 31. By adjusting the length between the two limiting rods 31 at opposite ends of the fixing frame 1, the length between the two sets of positioning rods 32 at both ends can be adjusted, which can accommodate battery boxes 20 of different lengths. At the same time, when the insulating sheet is pasted and the battery module is placed into the battery box 20, the limiting rods 31 at both ends of the fixing frame 1 can limit the battery module in the length direction X, so that the battery module can quickly align with the preset position and accurately enter the battery box 20, avoiding repeated adjustments to the position of the battery module.

[0053] See again Figure 4 The limiting rod 31 is slidably connected to the fixed frame 1 along the length direction X and extends out of the fixed frame 1 along the width direction Y. The positioning rod 32 is slidably connected to the limiting rod 31. The part of the limiting rod 31 that extends out of the fixed frame 1 is used to limit the part to be installed.

[0054] In practical applications, the limiting rod 31 slides along the length direction X of the fixing frame 1 to adjust the distance between the two positioning rods 32 to accommodate battery boxes 20 of different lengths. The positioning rod 32 and the limiting rod 31 are slidably connected. Specifically, the positioning rod 32 and the limiting rod 31 are slidably connected along the width direction Y of the fixing frame 1. This arrangement allows adjustment of the position of the positioning rod 32 relative to the battery box 20 along the width direction Y, making it easy to install the positioning rod 32 in different mounting holes of the battery box 20, thereby adjusting the position of the fixing frame 1 relative to the battery box 20 to accommodate insulating sheets at different positions.

[0055] The limiting rod 31 extends out of the fixing frame 1 along the width direction Y, so that the limiting rod 31 can more conveniently limit the battery module in the length direction X, thereby improving the assembly efficiency of the battery module.

[0056] In one embodiment, the positioning component 3 further includes a first locking member 33 and a second locking member 34. The fixing frame 1 has a first adjustment groove 11 along the length direction X. The limiting rod 31 is slidably disposed in the first adjustment groove 11. The first locking member 33 passes through the first adjustment groove 11 and the limiting rod 31 and is fixed to the fixing frame 1 to lock the limiting rod 31 and the fixing frame 1, preventing the limiting rod 31 from moving during the patch placement process. At the same time, the limiting rod 31 has a second adjustment groove 311 along the width direction Y of the fixing frame 1. The positioning rod 32 is slidably disposed in the second adjustment groove 311. The second locking member 34 passes through the second adjustment groove 311 and the positioning rod 32 and is fixed to the limiting rod 31 to lock the limiting rod 31 and the positioning rod 32, preventing the positioning rod 32 from moving during the patch placement process.

[0057] See Figure 5Along the width direction Y of the fixing frame 1, the length of the limiting rod 31 is L1, and the length of the rolling element 22 is L2, where L1 > L2. Since the limiting rod 31 achieves its limiting function by contacting the battery module through its own length, the longer the limiting rod 31, the better its limiting effect. Typically, along the width direction Y, the length of the battery module is greater than the length of the insulating sheet. Therefore, the length L1 of the limiting rod 31 is usually greater than the length L2 of the rolling element 22. Furthermore, since different types of battery modules have different sizes, setting the limiting rod 31 to a longer length along the width direction Y of the fixing frame 1 can better limit the battery module and accommodate more battery modules of various sizes.

[0058] Unlike existing technologies, this application provides a patching device 10 and a battery module patching equipment. The patching device 10 includes a fixing frame 1 and a patching assembly 2. The fixing frame 1 is used to connect the component to be patched. The patching assembly 2 includes a driving member 21 and a rolling member 22. The driving member 21 is slidably connected to the fixing frame 1, and the rolling member 22 is rotatably connected to the end of the driving member 21 away from the fixing frame 1. The rolling member 22 is used to patch the sheet material onto the component to be patched. The patching assembly 2 is provided with an isolation groove 24, which is used to isolate the release paper of the sheet material. Compared with existing technologies, when the driving member 21 moves along the length direction X of the fixing frame 1, the rolling member 22 rolls along the length direction X of the insulating sheet to evenly press the insulating sheet, so that the insulating sheet can be stably and tightly attached to the liquid cooling plate inside the battery box 20. By passing the release paper through the isolation groove 24 and then moving the isolation groove 24 to peel off the release paper, an efficient and stable peeling process can be achieved, which is suitable for large-scale production and automated production lines, improving production efficiency. This method not only reduces the risks of manual operation, but also ensures good adhesion of the insulating sheet, avoiding damage or affecting its performance.

[0059] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
