Description

Technical Field

[0001] This application relates to the field of battery cable tie technology, specifically to a battery cable tie separation device and a battery device. Background Technology

[0002] Cable ties are a convenient fastening tool widely used in electronics, electrical engineering, and mechanical fields. They can quickly bundle and secure different components together, ensuring the stability and safety of the connection while facilitating subsequent disassembly and maintenance.

[0003] After cable ties have finished their bundling function, the excess ends usually need to be removed to maintain the neatness of the structure and avoid potential interference. The traditional method is to cut the ends of the cable ties directly. However, since a clean cut is not possible, the cut ends may still interfere with surrounding components. Furthermore, cutting cable ties with a knife creates sharp edges that can easily cause wear to surrounding wire harnesses, busbars, and other sensitive components under vibration or other operating conditions, thus shortening the lifespan of these components and increasing the risk of equipment or system failure. Utility Model Content

[0004] The main objective of this application is to provide a battery cable tie separation device, which aims to solve the technical problems that existing cable tie cutting methods cannot achieve a clean cut and the cutting position produces a cross-section with a sharp edge, which easily wears down surrounding components and increases the risk of failure.

[0005] To achieve the above objectives, the battery cable tie separation device proposed in this application includes:

[0006] Tensioning mechanism, the tensioning mechanism is used to apply tension force to the target battery cable tie pre-bound to the component to be fixed, so that the main body of the target battery cable tie hugs the component to be fixed;

[0007] A heating element is used to generate localized high temperatures on the target battery cable tie to separate the end portion of the target battery cable tie from the main body portion by means of melting.

[0008] The battery cable tie separation device provided in this embodiment, after tightening the target battery cable tie through the tensioning mechanism and completing the binding and fixing of the component to be fixed, generates local high temperature at the boundary between the end portion and the main body portion of the target battery cable tie through a heating element, causing the root of the end portion to melt and break at high temperature, thereby achieving separation of the end portion and the main body portion. Compared with the traditional cutting method, this melting and breaking method will cause the cross-section of the target battery cable tie to form a target cross-section with more curved contours under surface tension. This target cross-section can minimize the length of the tail after the main body portion and the end portion are separated, and the target cross-section has fewer sharp edges, thereby avoiding interference and wear on surrounding components and improving product reliability. In addition, since there is no risk of wear, there is no need to specially limit the orientation of the target battery cable tie, and surrounding components do not need to avoid the cross-section of the target battery cable tie. This can improve the production efficiency of the product and improve space utilization. When the target battery cable tie is applied to battery packs and other battery devices, it can also improve its volumetric energy density by improving space utilization.

[0009] In some embodiments, the tensioning mechanism includes a traction device for pulling the end portion in a direction away from the main body portion to cause the main body portion to retract inward and hug the member to be fixed.

[0010] In this embodiment, the end portion is pulled by a traction device, which can complete the force application to the target battery cable tie with less interference, thereby enabling a smoother binding operation of the target battery cable tie.

[0011] In some embodiments, the traction device has a toothed structure on its surface, which is used to engage with the teeth on the surface of the end portion.

[0012] In this embodiment, the toothed structure on the surface of the traction device is used to engage with the teeth of the end part that have passed through the stop structure after pre-binding, so as to improve the connection stability between the end part and the traction device, prevent the end part from loosening relative to the traction device, and enable the traction device to stably pull the end part to move in a preset direction.

[0013] In some embodiments, the battery cable tie detachment device further includes a fixing base, the traction device is movably connected to the fixing base, and the heating element is disposed on the fixing base.

[0014] By setting a fixed base, the traction device and the heating element can be integrated into a common base, so that the relative position between the traction device and the heating element remains fixed. As the traction device pulls the end part to move in a preset direction, the relative distance between the end part and the heating element can be controlled more accurately, so that the heating element can more accurately heat the area of ​​the end part that needs to be melted.

[0015] In some embodiments, the heating element is slidably connected to the mounting base in a direction close to or away from the main body.

[0016] In this embodiment, the heating element is set to be adjustable relative to the fixed base. This allows for flexible adjustment of the heating element's position according to the actual area that needs to be melted at the end, ensuring that the heating element can accurately heat the target area. This makes it more adaptable to different target battery cable ties and items to be fixed, thus improving the applicability of the battery cable tie separation device.

[0017] In some embodiments, the battery cable tie separation device further includes an adhesive applicator disposed on the fixing base, the adhesive applicator being used to apply hot melt adhesive to the fusion surface of the main body portion.

[0018] After the main body and end of the target battery cable tie are separated by melting, hot melt adhesive can be applied to the target cross-section formed after melting using an adhesive applicator. This hot melt adhesive layer can cover the target cross-section and form a barrier, preventing burrs, sharp corners and other fine structures on the target cross-section from causing scratches and damage to surrounding components, thereby further improving the protective effect and the reliability of the product.

[0019] The adhesive application device, traction device, and heating element are all mounted on a fixed base, meaning they are integrated onto a common substrate. This keeps the relative positions of the adhesive application device, traction device, and heating element fixed, allowing for more accurate control of the relative position and distance between the adhesive application device and the target battery cable tie. Once the traction device pulls the end portion into place and the heating element completes the melting operation on the end portion, the adhesive application device can accurately apply adhesive to the target cross-section after the end portion has been melted.

[0020] In some embodiments, the fixing base is cylindrical, the heating element is annular, and the heating element is fitted into the opening at one end of the fixing base;

[0021] The traction device is movably connected to the inner cavity of the fixed base, and the traction device is used to pull the end portion through the inner periphery of the heating element and into the inner cavity of the fixed base.

[0022] In this embodiment, the heating element is housed within the cavity of the mounting base, which can, to some extent, prevent the heating element from accidentally contacting the human body or other external devices at high temperatures, thus providing better protection. Furthermore, because the heating element is arranged around the end portion, it can transfer heat to the end portion from various angles in the circumferential direction, ensuring that the end portion is heated circumferentially for faster melting and improving the consistency of tension throughout the circumferential direction, resulting in a fracture surface that more closely resembles a spherical structure.

[0023] In some embodiments, the battery cable tie separation device further includes a heat insulation layer covering the outer periphery and two end faces of the heating element.

[0024] Since the ring-shaped heating element heats the end portion mainly through contact between its inner periphery and the end portion, this embodiment provides a heat insulation layer. This ensures that the inner periphery of the heating element is exposed to the outside and can complete the melting operation normally, while also providing heat insulation for the outer periphery and two end faces of the heating element. This prevents the heat generated by the heating element from being excessively transferred to the fixing base and other peripheral components through its outer periphery and two end faces, thus avoiding local overheating problems. This also prevents operators from being burned by accidentally touching the peripheral components of the heating element.

[0025] In some embodiments, the battery cable tie separation device further includes an adhesive application device for applying hot melt adhesive to the fusion surface of the main body portion.

[0026] After the main body and end of the target battery cable tie are separated by melting, hot melt adhesive can be applied to the target cross-section formed after melting using an adhesive applicator. This hot melt adhesive layer can cover the target cross-section and form a barrier, preventing burrs, sharp corners and other fine structures on the target cross-section from causing scratches and damage to surrounding components, thereby further improving the protective effect and the reliability of the product.

[0027] In some embodiments, the battery cable tie separation device further includes a heat insulation layer; the heat insulation layer partially covers the surface of the heating element to expose a first side of the heating element, the first side being disposed toward the end portion.

[0028] This embodiment, by setting a heat insulation layer, ensures that the first side of the heating element used to directly heat the end part is exposed to the outside, so that the melting operation can be completed normally, while also providing heat insulation for other sides of the heating element. This prevents the heat generated by the heating element from being transferred excessively to the surrounding components through other sides, thus avoiding local overheating problems. This also prevents operators from being burned by accidentally touching the surrounding components of the heating element.

[0029] In some embodiments, the heating element is configured as an electric heating wire.

[0030] Electric heating wires have advantages such as high heating efficiency, high temperature control accuracy, good heating uniformity, long service life, relatively low cost, and easy installation and maintenance. They can stably and efficiently heat and melt the target battery cable ties.

[0031] In some embodiments, the battery cable tie separation device further includes a pressure sensing device for acquiring the real-time tension force applied by the tensioning mechanism to the target battery cable tie.

[0032] By setting up a pressure sensing device, it is easy to detect the real-time tension force applied to the target battery cable tie by the tensioning mechanism during the tensioning process. This helps operators judge whether the main body of the target battery cable tie has tightly hugged the surface of the part to be fixed based on the real-time tension force, and thus accurately determine whether the target battery cable tie has completed the binding and fixing of the part to be fixed.

[0033] In some embodiments, the pressure sensing device is electrically connected to the heating element; the pressure sensing device is used to send a separation signal to the heating element when the real-time tension force reaches a preset tension force threshold, and the heating element is used to generate local high temperature on the target battery cable tie when receiving the separation signal.

[0034] When the real-time tension force obtained by the pressure sensing device reaches the preset tension force threshold, it can be determined that the target battery cable tie has completed the binding and fixing of the component to be fixed. The pressure sensing device can then send a separation signal to trigger the heating element to heat and melt the target battery cable tie. There is no need for manual operation of the heating element, which improves the operating efficiency and enhances the automation and intelligence of the battery cable tie separation device.

[0035] In some embodiments, the heating element is used to form a target cross-section in the fusion region of the main body by means of melting, and the target cross-section is any one of an arc-shaped cross-section, a rounded corner cross-section, or a spherical cross-section.

[0036] The target cross-section formed on the target battery cable tie by the heating element through the melting method can be arc-shaped, rounded, or spherical. This target cross-section can minimize the length of the broken tail after the main part and the end part are separated. In addition, the target cross-section has fewer sharp edges, thereby avoiding interference and wear on surrounding components and improving the reliability of the product.

[0037] This application also proposes a battery device comprising a target battery cable tie, a plurality of battery cells, and a plurality of electrical components; the target battery cable tie is attached to any of the battery cells and / or any of the electrical components, and the target battery cable tie is used to form a target cross-section under the melting operation of the aforementioned battery cable tie separation device, the target cross-section being disposed toward another battery cell and / or another electrical component.

[0038] In this embodiment, after the target battery cable tie is tightened by the tensioning mechanism and the battery cells and / or electrical components are bundled and fixed, a heating element generates localized high temperature at the boundary between the end portion and the main body of the target battery cable tie. This causes the root of the end portion to melt and break at high temperature, thus separating the end portion from the main body. Compared with the traditional cutting method, this melting method creates a target cross-section with more curved contours under surface tension. This target cross-section can minimize the length of the broken tail after the main body and end portion are separated, and the target cross-section has fewer sharp edges, thereby avoiding interference and wear on surrounding components and improving product reliability. In addition, since there is no risk of wear, there is no need to specifically limit the orientation of the target battery cable tie. Other battery cells and electrical components in the battery device can directly face the target cross-section of the target battery cable tie. This can improve the production efficiency of the battery device, improve space utilization, and increase the volumetric energy density of the battery device by improving space utilization.

[0053] Cable ties are a convenient fastening tool widely used in electronics, electrical engineering, and mechanical fields. They can quickly bundle and secure different components together, ensuring the stability and safety of the connection while facilitating subsequent disassembly and maintenance.

[0054] After cable ties have finished binding, the excess ends usually need to be removed to maintain the neatness of the structure and avoid potential interference. For example... Figure 1 As shown, the traditional method is to directly cut off the end of the cable tie 100. However, since it is impossible to cut off the end cleanly, the cut end of the cable tie 100 may still interfere with surrounding components. In addition, cutting the cable tie 100 with a knife will produce a cross-section 110 with sharp edges. These sharp edges are prone to wear on sensitive components such as wire harnesses and busbars under vibration and other operating conditions, thereby shortening the service life of related components and increasing the risk of equipment or system failure.

[0055] To address the aforementioned problems and replace the existing method of directly cutting cable ties with a knife, thus avoiding adverse effects on surrounding components from the severed ends and sharp edges of the cable ties, this application provides a battery cable tie separation device. Please refer to [link to relevant documentation]. Figures 2 to 4 The battery cable tie detachment device includes:

[0056] Tensioning mechanism 1 is used to apply tension force to the target battery cable tie 200 pre-bound to the fastener (not shown in the figure) so that the main body 210 of the target battery cable tie 200 is attached to the fastener.

[0057] Heating element 2 is used to generate local high temperature on the target battery cable tie 200 so as to separate the end portion 220 of the target battery cable tie 200 from the main body portion 210 by means of melting.

[0058] In this embodiment, the first end of the target battery cable tie 200 is provided with a through hole, and a stop structure is provided inside the through hole. The second end of the target battery cable tie 200 is provided with multiple teeth arranged in an array along the extension direction of the target battery cable tie 200. The second end of the target battery cable tie 200 can pass through the through hole after wrapping around several components to be fixed. The snap-fit ​​between the teeth and the stop structure can prevent the second end of the target battery cable tie 200 from retracting, thereby completing the pre-binding of the target battery cable tie 200 to the components to be fixed. The closed-loop structure formed by the target battery cable tie 200 wrapping around the components to be fixed constitutes the main body 210 of the target battery cable tie 200, and the excess portion of the second end of the target battery cable tie 200 after passing through the through hole constitutes the end portion 220 of the target battery cable tie 200.

[0059] The tensioning mechanism 1 may include a limiting structure and a driving structure. The driving structure can move relative to the limiting structure under manual drive or under the drive of a driving device such as a motor, hydraulic component, or pneumatic component. In practical applications, the limiting structure can be used to limit and fix the first end of the target battery cable tie 200, and then the driving structure can be used to connect and drive the second end of the target battery cable tie 200 to move away from the main body 210, so that the main body 210 gradually contracts inward and hugs and adheres tightly to the surface of the part to be fixed; similarly, the limiting structure can also be used to limit and fix the second end of the target battery cable tie 200, and then the driving structure can be used to connect and drive the first end of the target battery cable tie 200 to move away from the second end, so that the main body 210 gradually contracts inward and hugs and adheres tightly to the surface of the part to be fixed. The aforementioned driving process is also the process by which the tensioning mechanism 1 applies tension to the target battery cable tie 200. When the tensioning operation is completed, the stop structure at the first end of the target battery cable tie 200 will engage with the corresponding teeth at the second end of the target battery cable tie 200, so that the main body 210 of the target battery cable tie 200 is stably maintained in the current clamped state, thereby achieving the binding and fixing of the component to be fixed. It can be understood that the smaller the cross-sectional area of ​​the position where the component to be fixed is bound by the target cable tie, the greater the inward contraction of the main body 210 of the target battery cable tie 200, and the longer the length of the end portion 220 of the target battery cable tie 200 after binding.

[0060] The heating element 2 can generate localized high temperatures on the target battery cable tie 200 using methods such as electric heating, induction heating, or infrared heating. The heating element 2 can be integrated into the tensioning mechanism 1 or separately installed from the tensioning mechanism 1; this is not limited here. After the target battery cable tie 200 is bundled under the tensioning action of the tensioning mechanism 1, the heating element 2 can heat the root of the end portion 220 of the target battery cable tie 200 (that is, the area of ​​the end portion 220 closest to the through hole), causing the root of the end portion 220 to melt and break at high temperature, thereby separating the end portion 220 from the main body portion 210. The cross-section of the target battery cable tie 200 after melting will form a target cross-section 230 with more curved contours under the influence of surface tension. This target cross-section 230 can minimize the length of the broken tail after the main body portion 210 and the end portion 220 are separated, and the target cross-section 230 has fewer sharp edges, thereby avoiding interference and wear on surrounding components.

[0061] Therefore, the battery cable tie separation device provided in this embodiment, after tightening the target battery cable tie 200 through the tensioning mechanism 1 and completing the binding and fixing of the component to be fixed, generates local high temperature at the boundary between the end portion 220 and the main body portion 210 of the target battery cable tie 200 through the heating element 2, causing the root of the end portion 220 to melt and break under high temperature, thereby achieving the separation of the end portion 220 and the main body portion 210. Compared with the traditional cutting method, this melting method will cause the cross-section of the target battery cable tie 200 to form a target cross-section 230 with more curved contours under surface tension. This target cross-section 230 can... To minimize the length of the broken tail after the main body 210 and the end part 220 are separated, and with fewer sharp edges on the target cross-section 230, interference and wear on surrounding components can be avoided, thus improving product reliability. In addition, since there is no risk of wear, there is no need to specifically limit the orientation of the target battery cable tie 200, and surrounding components do not need to avoid the cross-section of the target battery cable tie 200. This can improve product production efficiency and space utilization. When the target battery cable tie 200 is applied to battery packs and other battery devices, its volumetric energy density can also be increased by improving space utilization.

[0062] In some embodiments, refer to Figures 2 to 4 The heating element 2 is used to form a target cross-section 230 in the melting area of ​​the main body 210 by means of melting. The target cross-section 230 can be any one of an arc-shaped cross-section, a rounded cross-section, or a spherical cross-section.

[0063] The target cross-section 230 formed on the target battery cable tie 200 by the heating element 2 through the melting method can be arc-shaped, rounded, or spherical. The target cross-section 230 can minimize the length of the broken tail after the main body 210 and the end part 220 are separated. In addition, the target cross-section 230 has fewer sharp edges, thereby avoiding interference and wear on surrounding components and improving the reliability of the product.

[0064] In some embodiments, refer to Figures 2 to 4 The tensioning mechanism 1 includes a traction device 11, which is used to pull the end portion 220 in a direction away from the main body portion 210, so as to cause the main body portion 210 to retract inward and hug the member to be fixed.

[0065] Specifically, the traction device 11 can be connected to the end portion 220 of the target battery cable tie 200 by means of a pull rod, rope, swing arm or other structure, and pull the end portion 220 by manual drive or electric drive, hydraulic drive, pneumatic drive or other means, so as to drive the main body portion 210 of the target battery cable tie 200 to contract and hug inward, thereby realizing the binding and fixing of the component to be fixed.

[0066] In this embodiment, the traction device 11 pulls the end portion 220, which can complete the force application to the target battery cable tie 200 with less interference, thereby enabling the binding operation of the target battery cable tie 200 to be completed more smoothly.

[0067] In some embodiments, refer to Figures 2 to 4 The traction device 11 has a toothed structure 111 on its surface, which is used to engage with the teeth (not shown in the figure) on the surface of the end portion 220.

[0068] Specifically, as described in the above embodiments, during the inward retraction of the main body 210 of the target battery cable tie 200, multiple teeth of the end portion 220 will sequentially pass through the stop structure at the first end of the target battery cable tie 200 along a preset direction; when the target battery cable tie 200 completes the binding and fixing of the component to be fixed, the corresponding teeth of the end portion 220 will engage with the stop structure to prevent the end portion 220, which has already passed through the stop structure, from retracting in the opposite direction of the preset direction. In this embodiment, the toothed structure 111 on the surface of the traction device 11 is used to engage with the teeth of the end portion 220 that have already passed through the stop structure after pre-binding, so as to improve the connection stability between the end portion 220 and the traction device 11, prevent the end portion 220 from loosening relative to the traction device 11, and enable the traction device 11 to stably pull the end portion 220 to move along the preset direction.

[0069] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes a fixed base 3, a traction device 11 is movably connected to the fixed base 3, and a heating element 2 is disposed on the fixed base 3.

[0070] By setting a fixed base 3, the traction device 11 and the heating element 2 can be integrated into a common base, so that the relative position between the traction device 11 and the heating element 2 is kept fixed. Thus, when the traction device 11 pulls the end part 220 to move in a preset direction, the relative distance between the end part 220 and the heating element 2 can be controlled more accurately, so that the heating element 2 can more accurately heat the area of ​​the end part 220 that needs to be melted.

[0071] The fixing base 3 can be configured as a single base or as a shell forming a receiving space; no limitation is made here.

[0072] In some embodiments, refer to Figures 2 to 4 The heating element 2 is slidably connected to the fixed base 3 in the direction of approaching or away from the main body.

[0073] In this embodiment, the heating element 2 is set to be adjustable relative to the fixed base 3. This allows the position of the heating element 2 to be flexibly adjusted according to the area that the end part 220 actually needs to melt, ensuring that the heating element 2 can accurately heat the target area. This makes it more adaptable to different target battery cable ties 200 and the parts to be fixed, thus improving the applicability of the battery cable tie separation device.

[0074] The heating element 2 and the fixed base 3 can be slidably fitted using structures such as guide grooves and guide rails. After the heating element 2 is moved into place, it can be fixed on the fixed base 3 by means of threaded fasteners, snap-fit ​​connections, pin connections, etc.

[0075] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes an adhesive applicator (not shown in the figure), which is mounted on the mounting base 3 and is used to apply hot melt adhesive to the fusion surface of the main body 210.

[0076] After the main body 210 and the end part 220 of the target battery cable tie 200 are separated by melting, hot melt adhesive can be applied to the target cross-section 230 formed after melting using an adhesive applicator. This hot melt adhesive layer can cover the target cross-section 230 and form a barrier, which can prevent burrs, sharp corners and other fine structures that may exist on the target cross-section 230 from causing scratch damage to surrounding parts, thereby further improving the protection effect and further improving the reliability of the product.

[0077] The adhesive applicator, traction device 11, and heating element 2 are all mounted on the fixed base 3, which means that the adhesive applicator, traction device 11, and heating element 2 are integrated into a common base. This keeps the relative positions of the adhesive applicator, traction device 11, and heating element 2 fixed, thereby enabling more accurate control of the relative position and distance between the adhesive applicator and the target battery cable tie 200. When the traction device 11 pulls the end part 220 into place and the heating element 2 completes the melting operation of the end part 220, it can be ensured that the adhesive applicator can accurately apply adhesive to the target cross-section 230 after the end part 220 is melted.

[0078] In some embodiments, refer to Figures 2 to 4 The fixed base 3 is cylindrical, and the heating element 2 is annular. The heating element 2 is fitted into the opening at one end of the fixed base 3.

[0079] The traction device 11 is movably connected to the inner cavity of the fixed base 3. The traction device 11 is used to pull the end part 220 through the inner periphery of the heating element 2 and into the inner cavity of the fixed base 3.

[0080] In this embodiment, the heating element 2 is arranged in a ring shape. Indicatively, the outer periphery of the heating element 2 can be connected to the inner wall of the cylindrical fixing base 3, and the heating element 2 is open at one end near the fixing base 3. The end portion 220 of the target battery cable tie 200 passes through the inner periphery of the heating element 2 from the outside to the inside and is connected to the traction device 11. The traction device 11 can pull the end portion 220 to move in the direction of penetrating the inner cavity of the fixing base 3. During the movement of the end portion 220, the end portion 220 continuously passes over the inner periphery of the heating element 2. When the end portion 220 moves into place, that is, after the target battery cable tie 200 has completed the tensioning operation, the heating element 2 can directly perform the heating operation to melt the area of ​​the end portion 220 located on the inner periphery of the heating element 2.

[0081] In this embodiment, the heating element 2 is housed within the inner cavity of the fixing base 3, which can, to a certain extent, prevent the heating element 2 from accidentally contacting the human body or other external devices under high temperature conditions, thus providing better protection. Furthermore, since the heating element 2 is arranged around the end portion 220, it can transfer heat to the end portion 220 from various angles in the circumferential direction, ensuring that the end portion 220 is heated in the circumferential direction and melts more quickly. This also improves the consistency of tension throughout the circumferential direction, making the fracture surface after melting closer to a spherical structure.

[0082] The cylindrical fixing base 3 can refer to the gun head part of the cable tie gun. For details, please refer to the existing cable tie guns used to tighten cable ties, which will not be elaborated here.

[0083] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes a heat insulation layer 4, which covers the outer periphery and two end faces of the heating element 2.

[0084] Since the ring-shaped heating element 2 mainly heats the end portion 220 through contact between its inner periphery and the end portion 220, this embodiment provides a heat insulation layer 4. This ensures that the inner periphery of the heating element 2 is exposed to the outside and can complete the melting operation normally, while also providing heat insulation for the outer periphery and two end faces of the heating element 2. This prevents the heat generated by the heating element 2 from being transferred excessively to the fixing base 3 and other peripheral components through its outer periphery and two end faces, thus avoiding local overheating. This also prevents operators from being burned by accidentally touching the peripheral components of the heating element 2.

[0085] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes an adhesive applicator (not shown in the figure), which is used to apply hot melt adhesive to the molten surface of the main body 210.

[0086] After the main body 210 and the end part 220 of the target battery cable tie 200 are separated by melting, hot melt adhesive can be applied to the target cross-section 230 formed after melting using an adhesive applicator. This hot melt adhesive layer can cover the target cross-section 230 and form a barrier, which can prevent burrs, sharp corners and other fine structures that may exist on the target cross-section 230 from causing scratch damage to surrounding parts, thereby further improving the protection effect and further improving the reliability of the product.

[0087] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes a heat insulation layer 4; the heat insulation layer 4 partially covers the surface of the heating element 2 so that the first side of the heating element 2 is exposed and the first side is disposed toward the end portion 220.

[0088] In this embodiment, by setting a heat insulation layer 4, the first side of the heating element 2 used to directly heat the end portion 220 is exposed to the outside, so that the melting operation can be completed normally. At the same time, it provides heat insulation for the other sides of the heating element 2, preventing the heat generated by the heating element 2 from being transferred to the surrounding parts through the other sides and causing local overheating. This can prevent the operator from being burned by accidentally touching the surrounding parts of the heating element 2.

[0089] In some embodiments, refer to Figures 2 to 4 Heating element 2 is set as an electric heating wire.

[0090] The electric heating wire has advantages such as high heating efficiency, high temperature control accuracy, good heating uniformity, long service life, relatively low cost, and easy installation and maintenance. It can stably and efficiently heat and melt the target battery cable tie 200.

[0091] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device also includes a pressure sensing device (not shown in the figure), which is used to obtain the real-time tension force applied by the tensioning mechanism 1 to the target battery cable tie 200.

[0092] By setting up a pressure sensing device, it is convenient to detect the real-time tension force applied by the tensioning mechanism 1 to the target battery cable tie 200 during the tensioning process. This helps the operator to judge whether the main body 210 of the target battery cable tie 200 has tightly hugged the surface of the part to be fixed based on the real-time tension force, and thus accurately determine whether the target battery cable tie 200 has completed the binding and fixing of the part to be fixed.

[0093] In some embodiments, refer to Figures 2 to 4The pressure sensing device is electrically connected to the heating element 2; the pressure sensing device is used to send a separation signal to the heating element 2 when the real-time tension reaches the preset tension threshold, and the heating element 2 is used to generate local high temperature on the target battery cable tie 200 when it receives the separation signal.

[0094] When the real-time tension force obtained by the pressure sensing device reaches the preset tension force threshold, it can be determined that the target battery cable tie 200 has completed the binding and fixing of the component to be fixed. Then, the pressure sensing device can send a separation signal to trigger the heating element 2 to heat and melt the target battery cable tie 200. There is no need for manual operation of the heating element 2 to heat, thereby improving the operating efficiency and enhancing the automation and intelligence of the battery cable tie separation device.

[0095] In some embodiments, refer to Figures 2 to 4 The battery cable tie separation device includes a tensioning mechanism 1 and a heating element 2. The tensioning mechanism 1 applies tension to the target battery cable tie 200 pre-bonded to the component to be fixed, so that the main body portion 210 of the target battery cable tie 200 is held to the component to be fixed. The heating element 2 generates local high temperature on the target battery cable tie 200 to separate the end portion 220 of the target battery cable tie 200 from the main body portion 210 by melting. The tensioning mechanism 1 includes a traction device 11, which is used to pull along the distal end of the cable tie 200. Pulling the end portion 220 away from the main body 210 causes the main body 210 to retract inward and hug the component to be fixed; the traction device 11 has a toothed structure 111 on its surface, which is used to engage with the teeth on the surface of the end portion 220; the battery cable tie separation device also includes a fixing base 3, the traction device 11 is movably connected to the fixing base 3, and the heating element 2 is disposed on the fixing base 3; the heating element 2 is slidably connected to the fixing base 3 in the direction of approaching or moving away from the main body; electric The battery cable tie separation device also includes an adhesive applicator, which is mounted on a fixed base 3 and is used to apply hot melt adhesive to the fusion surface of the main body 210. The fixed base 3 is cylindrical, and the heating element 2 is annular, with the heating element 2 fitted into the opening at one end of the fixed base 3. A traction device 11 is movably connected to the inner cavity of the fixed base 3 and is used to pull the end part 220 through the inner periphery of the heating element 2 and into the inner cavity of the fixed base 3. The battery cable tie separation device also includes a heat insulation layer 4, which covers the outer periphery and two end faces of the heating element 2. The heating element 2 is configured as an electric heating wire. The battery cable tie separation device also includes a pressure sensing device, which is used to acquire the real-time tension force applied by the tensioning mechanism 1 to the target battery cable tie 200. The pressure sensing device is electrically connected to the heating element 2. The pressure sensing device is used to send a separation signal to the heating element 2 when the real-time tension force reaches a preset tension force threshold. The heating element 2 is used to generate local high temperature on the target battery cable tie 200 when it receives the separation signal.

[0096] This application also provides a battery device; please refer to [link / reference]. Figures 2 to 4 The battery device includes a target battery cable tie 200, a plurality of battery cells (not shown in the figure), and a plurality of electrical components (not shown in the figure); the target battery cable tie 200 is tied to any battery cell and / or any electrical component, and the target battery cable tie 200 is used to form a target cross-section 230 under the melting operation of the battery cable tie separation device in any of the above embodiments, the target cross-section 230 being disposed towards another battery cell and / or another electrical component.

[0097] The battery apparatus mentioned in this embodiment may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0098] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells; as an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form a single module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0099] In some embodiments, the battery device may be a battery pack, which includes a battery housing and one or more individual battery cells housed within the battery housing.

[0100] As an example, a battery cell assembly can be a battery module, which can be housed in a battery housing by fixing the battery module in the battery housing.

[0101] As an example, battery cell assemblies can also be housed in a battery housing by directly fixing multiple battery cells to the battery housing.

[0102] As an example, the battery enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the battery enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0103] As an example, the battery enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are respectively connected to the frame, so that the interior of the battery enclosure forms an enclosed space to house individual battery cells.

[0104] As an example, the battery pack can be part of the vehicle's chassis structure. For instance, the top cover of the battery pack can be at least part of the vehicle's floor, or the frame of the battery pack can be at least part of the vehicle's crossbeams and longitudinal beams.

[0107] For a detailed description of the battery cable tie separation device, please refer to the above embodiments. Since this battery device employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments. That is, after the target battery cable tie 200 is tightened by the tensioning mechanism 1 and the battery cell and / or electrical components are bundled and fixed, a local high temperature is generated at the boundary between the end portion 220 and the main body portion 210 of the target battery cable tie 200 by the heating element 2, causing the root of the end portion 220 to melt and break at high temperature, thereby achieving the separation of the end portion 220 from the main body portion 210. Compared to the traditional cutting method, this melting method causes the cross-section of the target battery cable tie 200 to form a cross-section with more curvature under surface tension. The target cross-section 230 of the surface profile can minimize the length of the broken tail after the main body 210 and the end part 220 are separated. The target cross-section 230 has fewer sharp edges, thereby avoiding interference and wear on surrounding components and improving product reliability. In addition, since there is no risk of wear, there is no need to specially limit the orientation of the target battery strap 200. Other battery cells and electrical components in the battery device can directly face the target cross-section 230 of the target battery strap 200. This can improve the production efficiency of the battery device, improve space utilization, and improve the volumetric energy density of the battery device by improving space utilization.
