A new energy battery cooling pipe insulation film laminating device

Abstract

The application provides a new energy battery cooling pipe insulation film fitting equipment, which comprises a rack, a material taking and unloading manipulator, a material loading and preheating table and a rubber coating roller cleaning assembly arranged on the rack. The alignment assembly is symmetrically arranged at the two ends of the hot pressing table. The sliding ring is pulled by the air cylinder to move along the arc-shaped support. The sliding guide action of the guide block and the guide groove is matched to make the rotating ring rotate and drive the telescopic column and the positioning block to synchronously extend to the end of the cooling pipe, so that the two end wear-resistant rollers are uniformly contacted and positioned on the outer wall of the cooling pipe. The structure can ensure that the two end shaft heights of the long cooling pipe are consistent before the film is attached, effectively eliminates the insulation film attachment skew or local overlapping problem caused by the axial offset of the pipe, avoids the wrinkles and bubble defects caused by inaccurate positioning in the film attaching process from the root, and significantly improves the attachment flatness and consistency of the insulation film on the surface of the cooling pipe.

Description

Technical Field

[0001] This invention relates to the field of new energy battery technology, and more specifically, to a device for bonding insulating film to cooling pipes of new energy batteries. Background Technology

[0002] The core of cooling pipe coating lies in altering the surface properties of the pipe wall, making it difficult for condensate droplets to adhere and causing them to slide off quickly, thereby significantly enhancing the heat exchange process. Simultaneously, this dense insulating film effectively prevents corrosive components in the cooling medium from contacting the metal substrate, preventing pitting and stress corrosion. Through its dual effect of improving heat exchange efficiency and extending equipment service life, the coating process plays a crucial role in enhancing the heat exchange efficiency and corrosion resistance of cooling components in the thermal management system of power batteries, and is an important technical means to ensure the safe and long-term operation of battery packs under complex operating conditions.

[0003] Currently, manual operation is commonly used in the bonding of insulating film onto cooling pipes for new energy batteries. Operators first place the cooling pipe on a heating platform. Once the pipe reaches the set temperature, a pre-cut insulating film is applied to its surface. A small hand roller is then used to apply pressure to the film, adhering it to the outer wall of the cooling pipe. However, manual operation relies on the operator's experience and the stability of their touch, making it difficult to guarantee uniform pressure application. Furthermore, the limited temperature control precision of the heating platform easily leads to uneven heating of the pipe. In addition, the manual operation environment makes it difficult to effectively control minute impurities such as dust and fibers, and the positioning of the pipe during heating and bonding relies solely on simple tooling or even visual alignment, failing to ensure precise alignment of the pipe's axis. The combined effect of these factors results in wrinkles, bubbles, and impurities commonly found on the surface of the bonded insulating film. Such bonding defects significantly weaken the bond between the insulating film and the cooling pipe. When the film-coated cooling pipe is installed in the battery cooling system of a new energy vehicle and subjected to the long-term alternating hot and cold working environment of the coolant, the poorly bonded film layer is prone to localized lifting or even large-area detachment. Once the insulating film detaches, the outer wall of the cooling pipe will lose reliable insulation protection, and the exposed metal pipe may cause leakage or short circuit risks in the complex electric field environment inside the battery pack, posing a serious threat to the battery safety and operational reliability of the entire vehicle. Summary of the Invention

[0004] The present invention aims to solve the problem that uneven pressure and impurities during manual film application on existing cooling pipes cause the film to wrinkle and bubble, and easily fall off after alternating hot and cold temperatures, leading to the risk of leakage and short circuit.

[0005] To address the aforementioned problems, this invention provides a new energy battery cooling pipe insulation film laminating device, comprising a frame, on which are mounted a material handling and unloading robot, a material feeding preheating table, a coating roller cleaning assembly, a hot press platform, a PET film unwinding and cutting assembly, a quick assembly / disassembly platform, and a rolling film hot press assembly; it also includes an alignment assembly to prevent the cooling pipe from shifting its axis during film lamination; and a linkage assembly to cooperate with the alignment assembly to prevent damage to the cooling pipe during positioning; the alignment assembly includes an arc-shaped bracket mounted on the hot press platform, with a guide groove on the inner side of the arc-shaped bracket, a slip ring slidably connected to the inner side of the arc-shaped bracket, a fixing ring on the inner side of the slip ring, a limit hole on the inner side of the fixing ring, a telescopic column inserted and slidably connected to the fixing ring, a lever mounted on the telescopic column, a telescopic rod inserted and slidably connected to the telescopic column, a positioning block connected to the end of the telescopic rod, an anti-wear roller installed in the positioning block, and a movable groove on the slip ring.

[0006] Furthermore, an elastic element is connected between the inner wall of the telescopic rod and the telescopic column, and an abutment block is provided inside the telescopic column, with one end of the abutment block facing the inner side of the telescopic column having an arc-shaped surface.

[0007] Furthermore, a locking block is provided on the abutment block, and an elastic element is connected between the abutment block and the inner wall of the telescopic column.

[0008] Furthermore, the number of the locking blocks is two sets, and the two sets of locking blocks are symmetrically arranged with the center line of the telescopic column as the axis of symmetry, and the cross-section of the locking blocks is the same as the shape of the limiting hole.

[0009] Furthermore, a set of rotating rings are respectively provided on both sides of the fixed ring. The rotating rings are provided with a moving groove, and the fixed ring is provided with a straight groove. The lever passes through the straight groove and is inserted into the moving groove.

[0010] Furthermore, the two sets of rotating rings are connected by a sliding plate, on which a guide block is installed and inserted into a guide groove.

[0011] Furthermore, the hot press platform is equipped with two sets of cylinders, and the output end of the cylinders is connected to a slip ring.

[0012] Furthermore, the linkage component includes a connecting sleeve mounted on the slip ring, a push plate is provided inside the connecting sleeve, and an elastic element is connected between the push plate and the inner side of the connecting sleeve.

[0013] Furthermore, a turntable is rotatably connected to the push plate, and an arc-shaped groove is provided on the turntable. Limiting grooves are provided on the inner walls of both the push plate and the connecting sleeve. A transmission block is installed on the turntable, and a transmission groove is provided on the inner wall of the connecting sleeve. The transmission block is inserted into the transmission groove.

[0014] Furthermore, a support rod passes through the arc-shaped groove, and an inner support block is connected to the end of the support rod. The support rod passes through the arc-shaped groove and also through the limiting groove.

[0015] The present invention provides a new energy battery cooling pipe insulating film bonding device, which, compared with the prior art, has the following beneficial effects, but is not limited to: 1. This invention utilizes symmetrically arranged alignment components at both ends of a hot press platform. A cylinder pulls a sliding ring along an arc-shaped support, and the sliding guidance of guide blocks and guide grooves causes the rotating ring to rotate, driving the telescopic column and positioning block to extend synchronously towards the end of the cooling pipe. This achieves uniform contact and positioning of the anti-wear rollers at both ends against the outer wall of the cooling pipe. This structure ensures that the axial height of both ends of a long cooling pipe remains consistent before film application, effectively eliminating the problem of skewed or partially overlapping insulation film caused by axial misalignment of the pipe components. It fundamentally avoids wrinkles and bubbles caused by inaccurate positioning during film application, significantly improving the flatness and consistency of the insulation film on the surface of the cooling pipe.

[0016] 2. This invention incorporates an elastic element and an arc-shaped contact block inside the telescopic column. When the anti-wear roller contacts the cooling pipe and receives a reaction force, the telescopic rod automatically retracts and pushes the contact block and locking block into the limiting hole, creating a distinct mechanical jerking sensation to indicate the need to stop the cylinder's advance. This structure achieves adaptive control of the cooling pipe's positioning and clamping force, ensuring sufficient contact between the anti-wear roller and the pipe surface for centering and positioning, while preventing excessive pressure from the anti-wear roller on the cooling pipe surface due to continuous cylinder pressure, thus avoiding indentations or deformation damage to the pipe. It ensures positioning reliability while maintaining the integrity of the pipe surface.

[0017] 3. This invention features a connecting sleeve on the slip ring that is linked to the alignment assembly. A push plate, turntable, and inner support block are installed within the connecting sleeve. As the slip ring moves towards the end of the cooling pipe, the inner support block is simultaneously inserted into the pipe opening. When the turntable is pushed at the end of the cooling pipe, the support rod is driven outwards through the cooperation of the transmission groove and the transmission block, achieving the expansion and support of the inner wall of the cooling pipe by the inner support block. This linkage structure can complete the internal pipe wall support while the external anti-wear roller is positioned, without the need for an additional power source. This effectively enhances the overall stability of the cooling pipe on the hot press platform, preventing radial runout or axial movement of the pipe during film application, and further ensuring the uniformity and continuity of the pressure applied to the insulating film by the rolling film hot press assembly.

[0027] See Figure 1 - Figure 9 An embodiment of the present invention provides a new energy battery cooling pipe insulation film laminating device, comprising a frame 1, on which are mounted a material handling and unloading robot 4, a material feeding preheating table 5, a coating roller cleaning assembly 6, a hot press table 7, a PET film unwinding and cutting assembly 8, a quick assembly / disassembly table 9, and a rolling film hot pressing assembly 10; it also includes an alignment assembly 2 to prevent the cooling pipe from shifting its axis during film lamination; and a linkage assembly 3 to cooperate with the alignment assembly 2 to prevent damage to the cooling pipe when positioning it; the alignment assembly 2 includes an arc-shaped bracket 21. Installed on the hot press platform 7, the inner side of the arc-shaped bracket 21 is provided with a guide groove 22, and the inner side of the arc-shaped bracket 21 is slidably connected with a slip ring 23. The inner side of the slip ring 23 is provided with a fixing ring 24, and the inner side of the fixing ring 24 is provided with a limit hole 25. A telescopic column 26 is inserted into and slidably connected to the fixing ring 24. A lever 27 is installed on the telescopic column 26. A telescopic rod 28 is inserted into and slidably connected to the telescopic column 26. The end of the telescopic rod 28 is connected with a positioning block 29. An anti-wear roller 210 is installed in the positioning block 29. The slip ring 23 is provided with a movable groove 219.

[0028] In this embodiment, two sets of alignment components 2 are provided, and the two sets of alignment components 2 are respectively located at the front and rear ends of the hot press stage 7. To facilitate the demonstration of the internal structure of the alignment components 2, Figure 3 and Figure 4 This is a schematic diagram of the alignment component 2 at the front end of the hot press stage 7. Figure 5 - Figure 11 These are all schematic diagrams of the alignment assembly 2 at the rear end of the hot press stage 7; After the equipment is started, the material handling and unloading robot 4 first places the cooling pipe that needs to be coated on the hot press platform 7. At this time, the alignment component 2 has not yet contacted the two ends of the cooling pipe. When the telescopic column 26 extends, the elastic element 211 connected inside it will also drive the telescopic rod 28 and the positioning block 29 to move together, so that the positioning block 29 gradually approaches the end of the cooling pipe. After the positioning block 29 moves a certain distance, the anti-wear roller 210 inside the positioning block 29 will first contact the outer wall of the cooling pipe. Since the anti-wear roller 210 is a rotatable structure, it can reduce friction damage to the surface of the cooling pipe.

[0029] See Figure 7 - Figure 9 Optionally, an elastic element 211 is connected between the telescopic rod 28 and the inner wall of the telescopic column 26, and an abutment block 212 is provided inside the telescopic column 26, with one end of the abutment block 212 facing the inner side of the telescopic column 26 having an arc-shaped surface.

[0030] In this embodiment, when the anti-wear roller 210 comes into contact with the cooling pipe, it will be subjected to a reaction force from the cooling pipe. At this time, the slip ring 23 continues to be pulled by the cylinder 221, which will cause the telescopic rod 28 to overcome the elastic force of the first elastic element 211 and retract into the telescopic column 26. The top of the telescopic rod 28 will abut against the arc-shaped surface of the abutment block 212 facing the inside of the telescopic column 26. Due to the arc-shaped surface design of the abutment block 212, the pushing action of the telescopic rod 28 will force the abutment block 212 to overcome the elastic force of the second elastic element 214 and move, thereby pushing the locking block 213 provided on the abutment block 212 to extend out from the inside of the telescopic column 26.

[0031] See Figure 9 Optionally, a locking block 213 is provided on the abutment block 212, and an elastic element 214 is connected between the abutment block 212 and the inner wall of the telescopic column 26.

[0032] In this embodiment, due to the arc-shaped surface design of the contact block 212, the pushing action of the telescopic rod 28 will force the contact block 212 to overcome the elastic force of the elastic element 214 and move, thereby pushing the locking block 213 provided on the contact block 212 to extend out from inside the telescopic column 26 and insert into the limiting hole 25 on the fixing ring 24.

[0033] See Figure 7 - Figure 9 Optionally, the number of locking blocks 213 is two sets, and the two sets of locking blocks 213 are symmetrically arranged with the center line of the telescopic column 26 as the axis of symmetry, and the cross section of the locking block 213 is the same as the shape of the limiting hole 25.

[0034] In this embodiment, since the cross-section of the locking block 213 is the same as the shape of the limiting hole 25, and the two sets of locking blocks 213 are symmetrically arranged with the center line of the telescopic column 26, the locking block 213 can be inserted into the limiting hole 25 to make the entire telescopic column 26 firmly limited. During this process, the operator can feel a noticeable jerking sensation. At this time, the pulling action of the cylinder 221 should be stopped immediately to avoid excessive external positioning force causing damage or deformation to the cooling pipe.

[0035] See Figure 6 and Figure 10 Optionally, a set of rotating rings 215 are provided on both sides of the fixed ring 24. The rotating rings 215 are provided with a toggle groove 216, and the fixed ring 24 is provided with a straight groove 220. The lever 27 passes through the straight groove 220 and is inserted into the toggle groove 216.

[0036] In this embodiment, when the rotating ring 215 rotates, the actuating groove 216 on the surface of the rotating ring 215 will actuate the lever 27 passing through the straight groove 220. However, the lever 27 also passes through the straight groove 220 on the fixed ring 24. The straight groove 220 will limit the lever 27, so that it can only move along the direction of the straight groove 220. This causes the lever 27 to drive the telescopic column 26 to extend out of the limiting hole 25 inside the fixed ring 24.

[0037] See Figure 6 and Figure 10 Optionally, the two sets of rotating rings 215 are connected by a sliding plate 217, on which a guide block 218 is installed and inserted into the guide groove 22.

[0038] In this embodiment, when the slip ring 23 moves, the slip ring 23 will drive the fixed ring 24 and the rotating ring 215 on its inner side to move together. The sliding plate 217 connected to the rotating ring 215 will drive the guide block 218 to slide in the guide groove 22, thereby forcing the guide block 218 to slide along the trajectory of the guide groove 22, and then causing the guide block 218 to drive the rotating ring 215 to rotate in the slip ring 23 through the sliding plate 217.

[0039] See Figure 4 Optionally, the hot press platform 7 is equipped with two sets of cylinders 221, and the output end of the cylinders 221 is connected to the slip ring 23.

[0040] In this embodiment, the two sets of cylinders 221 installed on the hot press platform 7 are then activated, and the output end of the cylinder 221 pulls the slip ring 23 to move towards the inside of the arc-shaped bracket 21.

[0041] In addition, see Figure 10 - Figure 11The linkage assembly 3 includes a connecting sleeve 31 mounted on the slip ring 23. A push plate 32 is disposed inside the connecting sleeve 31, and an elastic element 33 is connected between the push plate 32 and the inner side of the connecting sleeve 31. In this embodiment, when the slip ring 23 is pulled by the cylinder 221, the connecting sleeve 31 in the linkage assembly 3 will move towards the end of the cooling pipe along with the slip ring 23, and the push plate 32 and the turntable 34 disposed inside the connecting sleeve 31 will also move together, while the inner support block 38 gradually inserts into the opening of the cooling pipe.

[0042] See Figure 11 Optionally, a turntable 34 is rotatably connected to the push plate 32. An arc-shaped groove 35 is provided on the turntable 34. Limiting grooves 36 are provided on the inner walls of both the push plate 32 and the connecting sleeve 31. A transmission block 39 is installed on the turntable 34. A transmission groove 310 is provided on the inner wall of the connecting sleeve 31. The transmission block 39 is inserted into the transmission groove 310.

[0043] In this embodiment, when the turntable 34 rotates, the arc-shaped groove 35 on its surface will push the support rod 37 that passes through the arc-shaped groove 35. At the same time, the support rod 37 also passes through the limiting groove 36 on the inner wall of the push plate 32 and the connecting sleeve 31. Therefore, under the joint constraint of the arc-shaped groove 35 and the limiting groove 36, the support rod 37 will spread outward from the center of the connecting sleeve 31 along the limiting groove 36, so that the inner support block 38 connected to the end of the support rod 37 supports the inner wall of the cooling pipe outward.

[0044] See Figure 11 Optionally, a support rod 37 passes through the arc-shaped groove 35, and an inner support block 38 is connected to the end of the support rod 37. The support rod 37 passes through the arc-shaped groove 35 and also passes through the limiting groove 36.

[0045] In this embodiment, because the strut 37 also passes through the limiting groove 36 opened on the inner wall of the push plate 32 and the connecting sleeve 31, the strut 37 will spread outward from the center of the connecting sleeve 31 along the limiting groove 36 under the joint constraint of the arc groove 35 and the limiting groove 36.

[0046] In this invention, a new energy battery cooling pipe insulation film bonding device is used. After the device is started, the cooling pipe to be bonded is first placed on the hot press platform 7 by the material handling robot 4. At this time, the alignment component 2 has not yet contacted the two ends of the cooling pipe. Then, the two sets of cylinders 221 set on the hot press platform 7 are activated. The output end of the cylinder 221 pulls the slip ring 23 to move inward to the inside of the arc-shaped bracket 21. When the slip ring 23 moves, it will drive the fixed ring 24 and the rotating ring 215 on its inner side to move together. The sliding plate 217 connected to the rotating ring 215 will drive the guide block 218 to slide in the guide groove 22, thereby forcing the guide block 218 to slide along the trajectory of the guide groove 22. In turn, the guide block 218 drives the rotating ring 215 to rotate in the slip ring 23 through the sliding plate 217. When the rotating ring 215 rotates, the actuating groove 216 on the surface of the rotating ring 215 actuates the lever 27 passing through the straight groove 220. However, the lever 27 simultaneously passes through the straight groove 220 on the fixed ring 24, which limits the lever 27, allowing it to move only along the direction of the straight groove 220. This causes the lever 27 to drive the telescopic column 26 to extend from the limiting hole 25 inside the fixed ring 24. When the telescopic column 26 extends, the elastic element 211 connected inside it also drives the telescopic rod 28 and the positioning block 29 to move together, causing the positioning block 29 to gradually approach the end of the cooling pipe. After the positioning block 29 has moved a certain distance, the anti-wear roller 210 inside the positioning block 29 will first contact the outer wall of the cooling pipe. Since the anti-wear roller 210 is a rotatable structure, it can reduce frictional damage to the surface of the cooling pipe. When the anti-wear roller 210 comes into contact with the cooling pipe, it will be subjected to a reaction force from the cooling pipe. At this time, the slip ring 23 continues to be pulled by the cylinder 221, which will cause the telescopic rod 28 to overcome the elastic force of the first elastic element 211 and retract into the telescopic column 26. The top of the telescopic rod 28 will abut against the arc-shaped surface of the abutment block 212 facing the inside of the telescopic column 26. Due to the arc-shaped surface design of the abutment block 212, the pushing action of the telescopic rod 28 will force the abutment block 212 to overcome the elastic force of the second elastic element 214 and move, thereby pushing the locking block 213 provided on the abutment block 212 to extend out from inside the telescopic column 26 and insert into the limiting hole 25 on the fixing ring 24. The cross-section of the locking block 213 is the same as the shape of the limiting hole 25, and the two sets of locking blocks 213 are symmetrically arranged around the center line of the telescopic column 26. Therefore, after the locking block 213 is inserted into the limiting hole 25, the entire telescopic column 26 can be firmly limited. During this process, the operator can feel a noticeable jerking sensation. At this time, the pulling action of the cylinder 221 should be stopped immediately to avoid excessive external positioning force causing damage or deformation to the cooling pipe. By symmetrically arranging two sets of alignment components 2 on both sides of the hot press platform 7, the axis of both ends of the long cooling pipe can be kept consistent, effectively preventing the axis of the cooling pipe from shifting during the subsequent film application process, thereby avoiding defects such as PET film lamination position shift or air bubbles.

[0047] As the slip ring 23 is pulled by the cylinder 221, the connecting sleeve 31 in the linkage assembly 3 moves toward the end of the cooling pipe along with the slip ring 23. The push plate 32 and the turntable 34 inside the connecting sleeve 31 also move together, while the inner support block 38 gradually inserts into the opening of the cooling pipe. When the end of the cooling pipe contacts the turntable 34, a certain reaction force is generated, causing the end of the cooling pipe to push the push plate 32 to move within the connecting sleeve 31. When the push plate 32 is pushed, it compresses the elastic element 33 between itself and the inner side of the connecting sleeve 31. At the same time, when the turntable 34 is pushed, the transmission block 39 mounted on its side slides along the transmission groove 310 opened on the inner wall of the connecting sleeve 31 and drives the turntable 34 to rotate. When the turntable 34 rotates, the arc-shaped groove 35 on its surface actuates the support rod 37 passing through the arc-shaped groove 35. At the same time, the support rod 37 also passes through the limiting groove 36 on the inner wall of the push plate 32 and the connecting sleeve 31. Therefore, under the joint constraint of the arc-shaped groove 35 and the limiting groove 36, the support rod 37 will move outward from the center of the connecting sleeve 31 along the limiting groove 36, thereby causing the inner support block 38 connected to the end of the support rod 37 to support the inner wall of the cooling tube outward. The inner support block 38 supports the cooling tube from the inside, and with the contact positioning of the external anti-wear roller 210, it achieves stable clamping of both the inner and outer sides of the cooling tube. This not only prevents the cooling tube from radially jumping during the film application process, but also avoids damage to the cooling tube caused by rigid contact through the buffering effect of the elastic element 33. At the same time, the coordinated action of the linkage component 3 and the alignment component 2 ensures that the entire positioning process completes precise centering while protecting the cooling tube.

[0048] After positioning, the feeding and preheating station 5 preheats the cooling pipe. The PET film unwinding and cutting component 8 releases a fixed length of PET insulating film and cuts it. The rolling hot pressing component 10 applies the PET film to the surface of the cooling pipe. Simultaneously, the adhesive roller cleaning component 6 cleans the rollers used in the application process to ensure the quality of the film application. After the film application is completed, the material handling and unloading robot 4 removes the finished cooling pipe from the hot pressing station 7 and sends it out. The quick assembly and disassembly station 9 facilitates operators to quickly replace and maintain related components. The entire workflow is repeated cyclically, achieving efficient and automated application of the insulating film for the cooling pipes of new energy batteries.
