Description

TECHNICAL FIELD

[0001] The application relates to the technical field of battery production, and in particular to a self-recovery control component and a battery cell oven. BACKGROUND

[0002] In the related technical field, in the past, electronic devices and instruments use traditional fuses for overcurrent protection, but only one-time protection, and once the fuse is burned out, it must be replaced, and abnormal burning of the fuse may occur, such as at the moment of starting, plugging in the device, poor contact, and long use of the fuse, which may cause the fuse to burn out.

[0003] When the fuse is replaced, the same specification should be replaced according to the regulations, but in industrial sites, any fuse is often replaced with any fuse, which may cause incorrect replacement, and sometimes the overcurrent generated by the fault may burn out the components of the electronic device due to the oversized fuse, and accidents may occur due to the expansion of the fault.

[0004] Therefore, a more efficient and safe fuse device is urgently needed. CONTENT OF THE INVENTION

[0005] The application provides a self-recovery control component and a battery cell oven, which can quickly respond to temperature changes, ensure that the battery cell oven operates at the most suitable temperature, improve production efficiency, and prolong the service life of the battery cell oven.

[0006] In a first aspect, the application provides a self-recovery control component for protecting the heating circuit of a battery cell oven, the self-recovery control component comprising a bracket and a self-recovery fuse structure.

[0007] The bracket is installed in the battery cell oven. The self-recovery fuse structure is detachably connected to the bracket, and the self-recovery fuse structure is electrically connected to the heating circuit in cooperation with the bracket.

[0008] The self-recovery fuse structure can automatically open or close the circuit when the temperature in the battery cell oven changes, to protect the battery cell oven or maintain the temperature of the battery cell oven.

[0009] The self-recovery control component of the application can effectively reduce the frequent replacement cost caused by the burning of the fuse, because the self-recovery fuse structure can automatically recover after burning (the resistance becomes large enough), without the need to replace a new fuse.

[0010] The burning and recovery process of the self-recovery fuse structure is reversible, which means that the circuit can be cooled and closed again after burning, thereby avoiding production interruption caused by fuse damage.

[0011] The design of the self-restoring control component allows it to act at a specific temperature threshold, which helps to ensure that the battery oven operates within a safe and ideal temperature range, thereby improving the stability of the baking process and the quality of the baked battery cells. The self-restoring control component can protect the heating circuit of the battery oven as needed.

[0012] Specifically, the bracket is installed in a suitable position of the battery oven to ensure the stability and reliability of the bracket. The self-restoring fuse structure can be detachably connected with the bracket, which facilitates installation and maintenance and ensures that components such as the self-restoring fuse structure can be quickly replaced when necessary, such as when the self-restoring fuse structure reaches the end of its service life. The self-restoring fuse structure is indirectly electrically connected to the heating circuit through the connection with the bracket.

[0013] The self-restoring fuse structure functions to sense temperature changes inside the battery oven and automatically open or close the circuit accordingly. This automated response mechanism is crucial for protecting the battery oven from overheating damage. At the same time, the self-restoring fuse structure also ensures that the battery oven operates within a safe temperature range, thereby maintaining the normal working state of the oven and prolonging its service life.

[0014] In some examples, the bracket includes a first electrical connection portion, an insulating portion, and a second electrical connection portion, the insulating portion being disposed between the first electrical connection portion and the second electrical connection portion, the first electrical connection portion, the insulating portion, and the second electrical connection portion cooperating to open the heating circuit.

[0015] The open heating circuit has an anode end and a cathode end, the first electrical connection portion being connected to the anode end, and the second electrical connection portion being connected to the cathode end.

[0016] The self-restoring fuse structure is in communication with the first electrical connection portion and the second electrical connection portion, such that the self-restoring fuse structure is connected in series to the heating circuit.

[0017] The bracket described above in the present application includes a first electrical connection portion, an insulating portion, and a second electrical connection portion. The first electrical connection portion and the second electrical connection portion are separated from each other by the insulating portion, thereby effectively opening the heating circuit when needed.

[0018] When it is necessary to open the heating circuit, the circuit will exhibit a clear anode end and a cathode end. The first electrical connection portion will be connected to the anode end, and the second electrical connection portion will be connected to the cathode end, ensuring that the open state of the heating circuit is maintained.

[0019] In addition, the self-restoring fuse structure on the bracket can connect the first electrical connection portion and the second electrical connection portion, and the state of the self-restoring fuse structure will affect the on-off state of the heating circuit. The cooperation of the self-restoring fuse structure and the bracket can achieve the purpose of connecting the self-restoring fuse structure in series to the heating circuit. This design not only ensures the safety of the circuit, but also automatically restores when the circuit is abnormal, thereby improving the stability and reliability of the entire system.

[0020] In some examples, the bracket is detachably clamped with the battery cell oven, the position of the anode end is provided with a first clamping jaw, and the first power connection part is clamped to the first clamping jaw. The position of the cathode end is provided with a second clamping jaw, and the second power connection part is clamped to the second clamping jaw.

[0021] Alternatively, the bracket is welded with the battery cell oven, the position of the anode end is provided with a first welding point, and the first power connection part is welded to the first welding point. The position of the cathode end is provided with a second welding point, and the second power connection part is welded to the second welding point.

[0022] Alternatively, the bracket is fixedly connected with the battery cell oven, the position of the anode end is provided with a first mounting hole, and the first power connection part is provided with a second mounting hole. The first power connection part is fixedly connected to the anode end by a first fixing member, and the first fixing member is arranged through the first mounting hole and the second mounting hole. The position of the cathode end is provided with a third mounting hole, and the second power connection part is provided with a fourth mounting hole. The second power connection part is fixedly connected to the cathode end by a second fixing member, and the second fixing member is arranged through the third mounting hole and the fourth mounting hole.

[0023] The bracket is connected with the battery cell oven in a detachable manner. This design allows users to easily separate the bracket from the oven for maintenance or replacement. To ensure the stability of the connection, the position of the anode end is designed with a first clamping jaw that can be firmly clamped to the first power connection part. Similarly, the position of the cathode end is also provided with a second clamping jaw for clamping to the second power connection part. Such design not only ensures the reliability of electrical connection, but also facilitates the operator to carry out the loading and unloading work of the battery cell.

[0024] Another possible implementation is that the bracket is connected with the battery cell oven by welding. In this structure, the position of the anode end is specially designed with a first welding point, so that the first power connection part can be accurately welded and fixed on the first welding point. Similarly, the position of the cathode end is also provided with a second welding point, and the second power connection part is welded and fixed on the second welding point. Such design ensures that the electrical connection between the battery cell and the bracket is not only stable but also reliable.

[0025] In another embodiment, the bracket and the battery cell oven are combined by a fixed connection. Specifically, the anode end is designed with a first mounting hole, and the first power connection part is correspondingly provided with a second mounting hole. In order to ensure the stability of the connection, the first power connection part is fixedly connected with the anode end by a first fixing member, and the connection process involves the first fixing member passing through the first mounting hole and the second mounting hole. Similarly, a third mounting hole is arranged at the position of the cathode end, and a fourth mounting hole is correspondingly arranged on the second power connection part. In order to realize the stable connection between the second power connection part and the cathode end, a second fixing member is used, which also needs to pass through the third mounting hole and the fourth mounting hole, so as to ensure the close combination of the second power connection part and the cathode end.

[0026] In some examples, the first power connection part is provided with a first assembly part, the second power connection part is provided with a second assembly part, and the self-restoring fuse structure includes a fuse body, a first pin and a second pin connected to each other.

[0027] The first pin and the second pin are on the same side of the fuse body, the first pin is detachably connected to the first assembly part, and the second pin is detachably connected to the second assembly part.

[0028] The first power connection part is configured with a first assembly part, and the second power connection part is also configured with a second assembly part.

[0029] The first pin and the second pin are arranged on the same side of the fuse body. Such design makes the first pin convenient to be detached and connected with the first assembly part. Similarly, the second pin also has the characteristic of being detachable and can be connected with the second assembly part. Such structure design not only ensures the reliability of electrical connection, but also provides the convenience of quick replacement or maintenance when necessary.

[0030] In some examples, the first assembly part and the second assembly part are both plug-in structures, the first pin is plugged into the first assembly part, and the second pin is plugged into the second assembly part.

[0031] The first assembly part and the second assembly part both adopt plug-in structure design. In this design, the first pin is precisely inserted into the corresponding slot of the first assembly part, and the second pin is also inserted into the corresponding slot of the second assembly part, thereby realizing the stable connection between the two parts.

[0032] In some examples, the bracket is a cylindrical structure, the first power connection part and the second power connection part are respectively located at two ends of the cylindrical structure, and the insulating part is located in the middle of the cylindrical structure.

[0033] The cylindrical structure can reduce the processing difficulty, improve the production efficiency, and reduce the production cost.

[0034] In addition, the design of the cylindrical structure also has good mechanical strength and stability, and can withstand certain external force impact without deformation, thereby ensuring the stability and reliability of the power connection part. In practical application, this structural design helps to reduce the maintenance frequency and prolong the service life of the equipment. At the same time, due to its simple structure, it is convenient for standardized production, which is conducive to realizing large-scale industrialized production.

[0035] In some examples, polarity marks are provided on the self-restoring fuse structure and / or the bracket in different cases of self-restoring fuse structure being installed in positive and reverse directions. Alternatively, anti-reverse installation protrusions are provided on the self-restoring fuse structure and / or the bracket.

[0036] In the case of self-restoring fuse structure having polarity and existing correct installation (positive direction) and incorrect installation (reverse direction), in order to ensure the safety and correct operation of the equipment, obvious polarity marks are designed and provided on the self-restoring fuse structure itself and the bracket used in cooperation with it. The purpose of these polarity marks is to guide the user to distinguish the direction during installation and prevent incorrect installation, thereby avoiding possible equipment failure or safety accidents. In addition, in order to further enhance the correctness of installation, anti-reverse installation protrusions can also be provided on the self-restoring fuse structure and / or the bracket. The anti-reverse installation protrusions are a physical structure design, which prevents the possibility of reverse installation because the protrusions cannot match the installation hole or slot when installed in reverse, thereby ensuring that the self-restoring fuse structure can only be installed in the correct way at the physical level. This design not only improves the convenience of installation, but also greatly improves the safety performance of the overall system.

[0037] In some examples, the self-restoring fuse structure is a self-restoring thermal fuse. Alternatively, the self-restoring fuse structure is an insurance structure that can produce different resistance values at different temperatures.

[0038] The self-restoring fuse structure is usually in the form of a self-restoring thermal fuse. In addition to this, this self-restoring fuse structure can also be a special insurance structure that can exhibit different resistance values in different temperature environments, thereby realizing its self-restoring function.

[0039] In some examples, the self-restoring control component further includes an alarm unit, which includes at least one of a light alarm unit, a sound alarm unit, a vibration alarm unit, etc.

[0040] The alarm unit is connected to the circuit of the self-restoring thermal fuse and can timely issue an alarm signal when the temperature of the battery oven exceeds the preset safety range. The alarm unit refers to a device used to issue warning signals in a safety system. These alarm units can be light alarm units, sound alarm units, vibration alarm units, etc., which convey alarm information to people in different ways.

[0041] The light alarm unit reminds people by emitting light, which is used to attract attention visually. The sound alarm unit reminds people by emitting sound signals, which is often used for alarm in emergency situations. The vibration alarm unit reminds people by generating vibration, which is suitable for use in noisy environments or for warning the hearing impaired. These alarm units at least contain one of the above types, and these alarm methods can be used alone or combined according to actual needs to ensure that the operating personnel can be effectively reminded to take measures in different environments to prevent damage to the battery cell or safety accidents caused by temperature abnormalities, thereby ensuring the safety and reliability of the entire production process.

[0042] In a second aspect, the application provides a battery cell oven comprising the self-recovery control component and the shell as described above, and the self-recovery control component is arranged in the shell.

[0043] The battery cell oven with the self-recovery control component can quickly respond to temperature changes, ensuring that the battery cell oven operates at the most suitable temperature, which not only improves production efficiency but also prolongs the service life of the battery cell oven.

[0044] Specifically, the bracket is installed at a suitable position of the battery cell oven to ensure the stability and reliability of the bracket. The self-recovery fuse structure can be detachably connected with the bracket, which facilitates installation and maintenance and ensures that components such as the self-recovery fuse structure can be quickly replaced when necessary, such as when the self-recovery fuse structure reaches the service life. The self-recovery fuse structure is indirectly electrically connected to the heating circuit through the connection with the bracket.

[0045] The self-recovery fuse structure functions to sense temperature changes inside the battery cell oven and automatically open or close the circuit accordingly. This automated response mechanism is crucial for protecting the battery cell oven from overheating damage. At the same time, the self-recovery fuse structure also ensures that the battery cell oven operates within a safe temperature range, thereby maintaining the normal working state of the oven and prolonging its service life.

[0046] The use of the self-recovery control component reduces maintenance costs, eliminating the need for regular inspection and replacement, thereby reducing the long-term operating costs of the corresponding equipment. The self-recovery control component can quickly respond to temperature changes, ensuring that the battery cell oven operates at the most suitable temperature, which not only improves production efficiency but also prolongs the service life of the battery cell oven.

DETAILED DESCRIPTION

[0055] In order to make the technical solutions in the application or the prior art clearer, the drawings needed to be used in the examples or the prior art description will be briefly introduced as follows. Obviously, the drawings in the following description are only some examples of the application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.

[0056] In the past, traditional fuses were used for overcurrent protection in electronic devices and instruments, but they can only protect once, and must be replaced after being burned out. Moreover, abnormal burning of the fuses may occur, such as at the moment of starting, plugging in or out of a device, poor contact, and long use of the fuse, etc.

[0057] When replacing fuses, the same specifications should be replaced as required, but in industrial sites, it often happens that any fuse is replaced with another, leading to incorrect replacement. Sometimes, due to the excessive size of the fuse, the overcurrent generated by the fault burns out the components of the electronic equipment, causing the expansion of the fault accident.

[0058] The existing fuses in the prior art have the following problems:

[0059] 1. Ceramic fuses are disposable and must be replaced after melting, requiring continuous investment in purchasing and wasting costs.

[0060] 2. Replacing fuses requires frequent power-off of the equipment, damaging system stability.

[0061] 3. The rated current of the fuse cannot be effectively matched with the actual current.

[0062] 4. The temperature requirement for vacuum baking is relatively high. After the fuse burns out, the battery oven often alarms at low temperature, and the battery needs to be baked again, affecting product quality and performance.

[0063] 5. Replacing fuses requires frequent high-altitude operations, which is high-risk.

[0064] 4. During the vacuum baking process, the temperature requirement is quite high. If the fuse is unfortunately burned out, the battery oven will frequently send out low-temperature alarm signals, which will result in the battery having to be baked again. This not only affects the quality of the product, but also may adversely affect the performance of the product.

[0065] 5. During the replacement of fuses, workers often need to perform frequent high-altitude operations, which undoubtedly increases the safety risk of the work. Due to the particularity of the working environment, the safety risk of such high-altitude work cannot be ignored, and therefore appropriate safety measures need to be taken to reduce the risk.

[0066] In order to solve the above problems, the introduction of self-recovery control components provides a safer and more efficient solution. The self-recovery control component can automatically disconnect the circuit when the internal temperature of the battery oven rises to a certain threshold, preventing overheating. When the internal temperature of the oven decreases to a safe level, the self-recovery control component can automatically close the circuit without human intervention, ensuring that the oven can continue to work normally. This automated protection mechanism greatly reduces the frequent replacement cost and safety risk caused by fuse melting, while improving the efficiency and stability of the oven. In addition, the self-recovery control component is small in size and easy to install, without considering the polarity problem, making it more widely and conveniently used in battery ovens and other equipment. By using self-recovery control components, production interruptions caused by fuse replacement can be effectively avoided, ensuring the continuity of the production process and the consistency of product quality.

[0067] When performing vacuum baking, the temperature control of the battery oven is very important, as it relates to product quality and performance. If the battery oven's fuse burns out, the battery oven will frequently alarm due to the temperature being too low, which will force the operator to re-bake the battery, thereby affecting the final quality and performance of the product. In addition, when replacing the fuse, the worker needs to perform a climbing operation, which not only increases the operation difficulty, but also increases the safety risk. Therefore, in order to reduce these risks, additional safety measures must be taken.

[0068] The self-recovery control component provided by the present application is applied to a battery oven for lithium battery baking, and is mainly applied to the positive material baking process of the lithium battery. By accurately controlling the baking temperature and time, it is ensured that the positive material is uniformly and sufficiently baked in a safe environment, thereby improving its electrochemical performance. During the baking process, the component can automatically adjust the temperature to prevent material performance degradation due to excessive temperature or failure to achieve the expected baking effect due to excessive temperature. In addition, the control component also has a fault self-recovery function, which can quickly cut off the power supply and restore to a safe state once an abnormal condition is detected, ensuring the safety of the operator and the equipment.

[0069] The lithium battery baking self-recovery control component is a device for battery oven, which is used to control and manage the baking process of lithium batteries during production. The battery oven heats a certain part of the lithium battery through vacuum baking. Vacuum baking is mainly to remove moisture and impurities inside the battery to ensure the stability and safety of the battery performance. Through this baking process, the electrochemical performance of the lithium battery can be improved, the service life can be prolonged, and safety problems can be avoided during use.

[0070] In the related art battery oven, the baking fuse is usually a ceramic fuse. Once the fuse is blown, it cannot be used again, so it needs to be constantly purchased, resulting in continuous waste of cost. When the ceramic fuse is short-circuited and burned out, due to its material properties, the damage cannot be directly observed with the naked eye.

[0071] In actual application, the rated current of the fuse is often difficult to effectively match the actual current passing through, which may cause the fuse to work under inappropriate current, thereby affecting its performance and life.

[0072] During vacuum baking, the temperature requirement is very high. Once the fuse burns out, the battery oven will often alarm due to the temperature being too low, at which time the battery needs to be re-baked, which not only affects the quality of the product, but also adversely affects the performance of the product.

[0073] To solve the above technical problems, please refer to Figures 1-5 As shown in the first aspect of the present application, a self-recovery control component is proposed, which can quickly respond to temperature changes and ensure that the battery oven operates at the most suitable temperature, thereby improving production efficiency and prolonging the service life of the battery oven.

[0074] Referring to Figures 1-3 As shown in some examples, the self-recovery control component is used to protect the heating circuit of the battery oven, and the self-recovery control component includes a bracket 100 and a self-recovery fuse structure 200.

[0075] The bracket 100 is installed on the battery oven. The self-recovery fuse structure 200 is detachably connected to the bracket 100, and the self-recovery fuse structure 200 is electrically connected to the heating circuit in cooperation with the bracket 100.

[0076] Among them, the self-recovery fuse structure 200 can automatically open or close the circuit when the temperature in the battery oven changes, so as to protect the battery oven or maintain the temperature of the battery oven.

[0077] The self-recovery control component of the present application can effectively reduce the frequent replacement cost caused by the fuse blowing, because the self-recovery fuse structure 200 can automatically recover after blowing (the resistance becomes large enough), without the need to replace a new fuse.

[0078] The blowing and recovery process of the self-recovery fuse structure 200 is reversible, which means that the circuit can be cooled and re-closed after blowing, thereby avoiding production interruption caused by fuse damage.

[0079] The design of the self-recovery control component allows it to act at a specific temperature threshold, which helps to ensure that the battery oven operates within a safe and ideal temperature range, thereby improving the stability of the baking process and the quality of the battery after baking. The self-recovery control component can provide necessary protection to the heating circuit of the battery oven.

[0080] Specifically, the bracket 100 is installed at a suitable position of the battery oven to ensure the stability and reliability of the bracket 100. The self-recovery fuse structure 200 can be detachably connected to the bracket 100, which facilitates installation and maintenance and ensures that components such as the self-recovery fuse structure 200 can be quickly replaced when necessary, such as when the self-recovery fuse structure 200 reaches the end of its service life. The self-recovery fuse structure 200 is indirectly electrically connected to the heating circuit through the connection with the bracket 100.

[0081] The self-restoring fuse structure 200 functions in that it can sense the temperature change inside the battery oven and automatically open or close the circuit accordingly. This automatic response mechanism is crucial for protecting the battery oven from overheating damage. At the same time, the self-restoring fuse structure 200 can also ensure that the battery oven operates within a safe temperature range, thereby maintaining the normal working state of the oven and prolonging its service life.

[0082] The use of the self-restoring control component reduces maintenance costs, eliminating the need for regular inspection and replacement, thereby reducing the long-term operating costs of the corresponding equipment. The self-restoring control component can quickly respond to temperature changes, ensuring that the battery oven operates at the most suitable temperature, not only improving production efficiency but also prolonging the service life of the battery oven.

[0083] The normal temperature zero-power resistance of the self-restoring control component of the present application can be made very small, that is, the self-restoring control component can have a very small resistance value at normal temperature conditions even without external power (i.e., in a zero-power state). For high-current products, the resistance value of the self-restoring control component is only a few milliohms. Because the resistance is small, the heat generated (i.e., the power consumption on the road) is very low and can be ignored. In addition, the size of this component is relatively small.

[0084] The self-restoring control component can be connected in series in a vulnerable circuit for overcurrent protection and temperature fuse use, with a sudden resistance change speed of several milliseconds, a small thermal capacity, a short recovery time, impact resistance, and a cycle protection of more than 8000 times (exemplary description, specific settings according to actual conditions). The self-restoring control component can be used as a temperature fuse, thus to some extent embodying the performance and function of a temperature fuse in the circuit. It achieves the dual protection function of overcurrent protection and overtemperature protection in the circuit.

[0085] The self-restoring control component of the present application has no polarity, small impedance, and is easy to install. It can be connected in series in the circuit of the protected electrical appliance, and both DC and AC power sources can be used. The action principle of the self-restoring control component is a dynamic balance of energy. The current flowing through the self-restoring control component generates heat due to the fuse, and all or part of the generated heat is dissipated into the environment, and the heat that has not been dissipated increases the temperature of the component.

[0086] In normal operation, the temperature is low, and the generated heat and dissipated heat reach a balance. The self-restoring control component is in a low resistance state and does not act. When the current flowing through the fuse increases or the environmental temperature rises, but if the balance of generated heat and dissipated heat is reached, the self-restoring control component still does not act.

[0087] When the current or ambient temperature increases again, the self-restoring control component will reach a higher temperature. If the current or ambient temperature continues to increase at this time, the heat generated will be greater than the heat dissipated, causing the self-restoring control component temperature to increase rapidly. At this stage, a small change in temperature will cause a large increase in resistance, and the self-restoring control component is in a high-resistance protection state. The increase in impedance limits the current, which drops sharply in a very short time, thereby protecting the circuit equipment from damage. As long as the heat generated by the applied voltage is sufficient to dissipate the heat generated by the self-restoring control component, the component can remain in the active state (high resistance) at all times.

[0088] When the applied voltage disappears, the self-restoring control component will automatically restore.

[0089] These characteristics of the self-restoring control component make it have a wide application prospect in electronic equipment. Not limited to the application to the battery oven in this application, it can have more applications, such as in power management, motor drive, lighting system, battery protection, and overcurrent and overtemperature protection of various electronic equipment, the self-restoring control component can provide more reliable and durable protection. Due to its recyclable characteristics, maintenance costs and downtime are reduced, and the stability and safety of the equipment are improved. In addition, the non-polarity characteristics of the self-restoring control component simplify the circuit design, making engineers more flexible when designing circuits, and eliminating the risk of incorrect installation caused by polarity problems. In practical applications, the fast response and high impact resistance of the self-restoring control component make it an ideal choice for protecting sensitive electronic equipment from current and temperature abnormalities.

[0090] Referring to Figures 1-3 In some examples, the bracket 100 includes a first power connection part 110, an insulating part 120, and a second power connection part 130. The insulating part 120 is arranged between the first power connection part 110 and the second power connection part 130. The first power connection part 110, the insulating part 120, and the second power connection part 130 cooperate to disconnect the heating circuit.

[0091] The disconnected heating circuit has an anode end and a cathode end. The first power connection part 110 is connected to the anode end, and the second power connection part 130 is connected to the cathode end.

[0092] The self-restoring fuse structure 200 is connected between the first power connection part 110 and the second power connection part 130, so that the self-restoring fuse structure 200 is connected in series to the heating circuit.

[0093] The bracket 100 described above includes a first power connection part 110, an insulating part 120, and a second power connection part 130. The first power connection part 110 and the second power connection part 130 are separated from each other by the insulating part 120, so that the heating circuit can be effectively disconnected when needed.

[0094] When the heating circuit needs to be disconnected, the circuit presents a clear anode end and a cathode end. The first electrical connection part 110 is connected to the anode end, and the second electrical connection part 130 is connected to the cathode end, ensuring that the disconnected state of the heating circuit is maintained.

[0095] In addition, the self-restoring fuse structure 200 on the bracket 100 can connect the first electrical connection part 110 and the second electrical connection part 130, and the state of the self-restoring fuse structure 200 will affect the on-off of the heating circuit. The cooperation of the self-restoring fuse structure 200 and the bracket 100 can achieve the purpose of connecting the self-restoring fuse structure 200 in series to the heating circuit. This design not only ensures the safety of the circuit, but also automatically restores when the circuit is abnormal, improving the stability and reliability of the entire system.

[0096] In addition, the material selection and design of the self-restoring fuse structure 200 enable it to quickly melt when the rated current is exceeded, thereby protecting the entire baking system from damage. After melting, the structure can automatically restore its conductive performance after cooling, without the need for manual replacement, greatly reducing maintenance costs and operational complexity. This self-restoring feature enables the battery cell oven to protect itself when encountering current abnormalities, while reducing production interruptions and safety risks caused by frequent replacement of fuses.

[0097] In some examples, the bracket 100 is detachably clamped with the battery cell oven, the position of the anode end is provided with a first clamping jaw, the first electrical connection part 110 is clamped to the first clamping jaw, the position of the cathode end is provided with a second clamping jaw, and the second electrical connection part 130 is clamped to the second clamping jaw.

[0098] The bracket 100 is connected to the battery cell oven in a detachable manner. This design allows users to easily separate the bracket 100 from the oven for maintenance or replacement. To ensure the stability of the connection, the first clamping jaw is designed at the position of the anode end, which can be firmly clamped to the first electrical connection part 110. Similarly, the second clamping jaw is provided at the position of the cathode end for clamping to the second electrical connection part 130. Such a design not only ensures the reliability of the electrical connection, but also facilitates the loading and unloading of battery cells by the operator.

[0099] Alternatively, the bracket 100 is welded to the battery cell oven, the first welding point is provided at the position of the anode end, and the first electrical connection part 110 is welded to the first welding point. The second welding point is provided at the position of the cathode end, and the second electrical connection part 130 is welded to the second welding point.

[0100] In another possible implementation, the bracket 100 is connected to the battery oven by welding. In this structure, the anode end is provided with a first welding point at which the first electrical connection part 110 is welded and fixed. Similarly, the cathode end is provided with a second welding point at which the second electrical connection part 130 is welded and fixed. This design ensures that the electrical connection between the battery and the bracket 100 is both stable and reliable.

[0101] This welding method provides a more durable and stable connection, reducing the risk of poor contact caused by mechanical clamping. Through precise welding processes, it can be ensured that the anode end and the cathode end of the battery oven form a firm electrical connection with the corresponding electrical connection parts, thereby improving the overall efficiency of electrical energy transmission. In addition, the durability of the welded connection also means that less maintenance is required in daily use, further reducing maintenance costs and downtime.

[0102] Alternatively, the bracket 100 is fixedly connected to the battery oven, the anode end is provided with a first mounting hole, the first electrical connection part 110 is provided with a second mounting hole, the first electrical connection part 110 is fixedly connected to the anode end by a first fixing member, and the first fixing member passes through the first mounting hole and the second mounting hole. The cathode end is provided with a third mounting hole, the second electrical connection part 130 is provided with a fourth mounting hole, the second electrical connection part 130 is fixedly connected to the cathode end by a second fixing member, and the second fixing member passes through the third mounting hole and the fourth mounting hole.

[0103] In another embodiment, the bracket 100 is fixedly connected to the battery oven. Specifically, the anode end is provided with a first mounting hole, and the first electrical connection part 110 is provided with a second mounting hole. To ensure the stability of the connection, the first electrical connection part 110 is fixedly connected to the anode end by a first fixing member, and the connection process involves the first fixing member passing through the first mounting hole and the second mounting hole. Similarly, the cathode end is provided with a third mounting hole, and the second electrical connection part 130 is provided with a fourth mounting hole. To achieve a stable connection between the second electrical connection part 130 and the cathode end, a second fixing member is used, which also needs to pass through the third mounting hole and the fourth mounting hole, thereby ensuring the close connection between the second electrical connection part 130 and the cathode end.

[0104] This design ensures that the electrical connection between the electrical connection part and the battery cell oven will not be affected even if thermal expansion occurs during operation, thereby ensuring the continuity and stability of current transmission. At the same time, since the connection between the electrical connection part and the battery cell oven uses a fixing part, it not only simplifies the maintenance process, but also improves the safety of operation. When the electrical connection part needs to be replaced or repaired, the worker does not need to climb, but only needs to simply disassemble the fixing part to easily complete the operation, greatly reducing the safety risk. In addition, this structural design also facilitates the quick installation and disassembly of the battery cell oven, improving the maintenance efficiency of the equipment.

[0105] In addition, the battery cell oven also includes at least one temperature sensor for real-time monitoring of the temperature inside the oven, ensuring that the battery cells are baked within a safe temperature range. The temperature sensor is connected to the control unit, which automatically adjusts the heating power in the oven according to the data provided by the temperature sensor to maintain the set baking temperature. In some embodiments, the control unit can also automatically switch different heating modes according to the baking stage of the battery cells, thereby improving the baking efficiency and ensuring the quality of the battery cells.

[0106] Referring to Figures 1-3 As shown in some examples, the first electrical connection part 110 is provided with a first assembly part 140, the second electrical connection part 130 is provided with a second assembly part 150, and the self-restoring fuse structure 200 includes a fuse body 210, a first pin 220 and a second pin 230 connected to each other.

[0107] The first pin 220 and the second pin 230 are on the same side of the fuse body 210, the first pin 220 is detachably connected to the first assembly part 140, and the second pin 230 is detachably connected to the second assembly part 150.

[0108] The first electrical connection part 110 described above is configured with a first assembly part 140, and at the same time, the second electrical connection part 130 is also configured with a second assembly part 150.

[0109] The first pin 220 and the second pin 230 are arranged on the same side of the fuse body 210. Such a design makes the first pin 220 easy to disassemble and connect with the first assembly part 140. Similarly, the second pin 230 also has the characteristics of being detachable and can be connected with the second assembly part 150. This structural design not only ensures the reliability of electrical connection, but also provides the convenience of quick replacement or repair when necessary.

[0110] With this design, when the current exceeds the predetermined safety threshold, the resistance of the fuse body 210 will increase or automatically fuse, thereby cutting off the circuit and protecting the battery oven from damage. After the current is restored, the fuse body 210 will return to the resistance value during work, and the self-restoring fuse structure 200 can be used repeatedly for thousands of times. After the self-restoring fuse structure 200 reaches the service life, the user can easily replace the fuse body 210 without replacing the entire electrical connection assembly, greatly reducing the maintenance cost and time. In addition, since the first pin 220 and the second pin 230 are detachable, it provides convenience for on-site replacement, further reducing the safety risks caused by replacing the fuse.

[0111] The fuse body 210 can include a working part of a functional part and a packaging part of a sealed protective functional part, so as to form a safe and stable fuse body 210. The first pin 220 and the second pin 230 are respectively connected to both ends of the functional part and can electrically connect the functional part to the heating circuit.

[0112] Referring to Figures 1-3 As shown in some examples, the first assembly part 140 and the second assembly part 150 are both plug-in structures, the first pin 220 is plugged into the first assembly part 140, and the second pin 230 is plugged into the second assembly part 150.

[0113] The first assembly part 140 and the second assembly part 150 both adopt a plug-in structure design. In this design, the first pin 220 is precisely inserted into the corresponding slot of the first assembly part 140, and the second pin 230 is also inserted into the corresponding slot of the second assembly part 150, thereby achieving a stable connection between the two components.

[0114] This plug-in structure design allows users or operators to quickly and easily connect and disconnect without using any tools. The plug-in part is usually made of durable materials to ensure good contact performance and mechanical strength during frequent plugging and unplugging. In addition, the plug-in structure design also considers the anti-misplug feature, ensuring that the connection can only be completed when properly aligned, thereby avoiding electrical failures caused by improper operation. In some specific applications, the plug-in structure may also have waterproof or dustproof functions to adapt to harsh working environments.

[0115] Referring to Figures 1-3 As shown in some examples, an isolation protrusion 240 is provided between the first pin 220 and the second pin 230. The safety of the first pin 220 and the second pin 230 is ensured.

[0116] An isolation protrusion 240 is arranged between the first pin 220 and the second pin 230. Such a design is to ensure the safety of the first pin 220 and the second pin 230 when electrically connected, to prevent dangerous situations such as short circuit or electric shock caused by accidental contact.

[0117] The role of the isolation protrusion 240 is to prevent short circuit phenomenon caused by improper operation during plugging. It ensures that when one pin is inserted into its corresponding assembly part, the other pin will not accidentally contact the circuit, thereby avoiding potential electrical failure. In addition, the design of the isolation protrusion 240 also increases the accuracy of plugging, because the operator will feel a certain resistance when inserting the pin, which helps to confirm whether the pin is correctly inserted into the designated assembly part. This design detail not only improves the safety of electronic equipment, but also enhances the user experience.

[0118] Referring to Figures 1-3 In some examples, the support 100 is a cylindrical structure, the first electrical connection part 110 and the second electrical connection part 130 are respectively at both ends of the cylindrical structure, and the insulating part 120 is in the middle of the cylindrical structure. The cylindrical structure can reduce the difficulty of processing, improve the production efficiency, and reduce the production cost.

[0119] In addition, the cylindrical structure design also has good mechanical strength and stability, and can withstand a certain external force impact without deformation, thereby ensuring the stability and reliability of the electrical connection part. In practical application, this structure design helps to reduce the maintenance frequency and prolong the service life of the equipment. At the same time, due to its simple structure, it is easy to standardize production, which is conducive to realizing large-scale industrialized production.

[0120] The support 100 with the above structure presents a cylindrical structure. The first electrical connection part 110 and the second electrical connection part 130 are respectively arranged at the two opposite end faces of the cylindrical structure. At the same time, the insulating part 120 is arranged in the middle part of the cylindrical structure. The adoption of this cylindrical structure design can effectively reduce the difficulty in the processing process, thereby improving the production efficiency and greatly reducing the production cost.

[0121] Referring to Figure 4 and Figure 5 In some examples, the polarity mark 300 is arranged on the self-restoring fuse structure 200 and / or the support 100 in different cases of the self-restoring fuse structure 200 being in normal and reverse installation. Alternatively, an anti-reverse installation protrusion is arranged on the self-restoring fuse structure 200 and / or the support 100.

[0122] In the self-restoring fuse structure 200 with polarity, there are cases of correct installation (positive installation) and incorrect installation (reverse installation). In order to ensure the safety and correct operation of the equipment, the self-restoring fuse structure 200 itself and the bracket 100 used in conjunction with it are specially designed and provided with obvious polarity marks 300. The purpose of these polarity marks 300 is to guide the user to distinguish the direction during installation, prevent incorrect installation, and avoid possible equipment failure or safety accidents. In addition, in order to further enhance the correctness of the installation, the self-restoring fuse structure 200 and / or the bracket 100 may also be equipped with anti-reverse installation protrusions. The anti-reverse installation protrusions are a physical structure design. The anti-reverse installation protrusions physically prevent the possibility of reverse installation, as the protrusions cannot match the installation hole or slot when installed in reverse, thereby ensuring that the self-restoring fuse structure 200 can only be installed in the correct way at the physical level. This design not only improves the convenience of installation, but also greatly improves the safety performance of the overall system.

[0123] Through these marks or protrusions, the correctness of the self-restoring fuse structure 200 during installation can be ensured, and equipment damage or safety accidents caused by incorrect installation can be avoided. In addition, these design details also reflect the consideration of user operation safety and convenience, making maintenance work more convenient and safe. In actual application, such design can significantly reduce the failure rate caused by improper operation and improve the stable operation time of the equipment.

[0124] In some examples, the self-restoring fuse structure 200 is a self-restoring thermal fuse. Alternatively, the self-restoring fuse structure 200 is an insurance structure that can produce different resistance values at different temperatures.

[0125] The self-restoring fuse structure 200 is usually in the form of a self-restoring thermal fuse. In addition to this, this self-restoring fuse structure 200 can also be a special insurance structure that can exhibit different resistance values in different temperature environments, thereby realizing its self-restoring function.

[0126] In other examples, the self-restoring fuse structure 200 can include a built-in temperature sensor that can monitor abnormal temperature rise and trigger the self-restoring mechanism of the fuse structure when the preset threshold is reached. In addition, some self-restoring fuse structures 200 can also integrate a fault indication function, which can warn the user through color change or electronic signal after the fuse structure acts, thereby facilitating timely discovery and handling of problems. These designs not only improve the self-protection ability of the equipment, but also reduce maintenance costs and downtime, ensuring long-term stable operation of the system.

[0127] In some examples, the self-restoration control component further comprises an alarm unit, which includes at least one of a light alarm unit, a sound alarm unit, a vibration alarm unit, and the like.

[0128] The alarm unit is connected to the circuit of the self-restoration thermal fuse and can send out an alarm signal in time when the temperature of the battery oven exceeds the preset safety range. The alarm unit refers to a device used to send warning signals in a safety system. These alarm units can be light alarm units, sound alarm units, vibration alarm units, etc., which convey alarm information to people through different ways.

[0129] Among them, the light alarm unit reminds people by emitting light, which is used to attract attention visually. The sound alarm unit prompts danger or abnormal situation by emitting sound signals, which is often used for alarm in emergency situations. The vibration alarm unit attracts people's attention by generating vibration, which is suitable for use in noisy environments or for warning the hearing-impaired. These alarm units at least contain one of the above types, and these alarm methods can be used alone or combined according to actual needs to ensure that the operating personnel can be effectively reminded to take measures in different environments to prevent battery damage or safety accidents caused by temperature abnormalities, thereby ensuring the safety and reliability of the entire production process.

[0130] In the second aspect, the application provides a battery oven comprising the self-restoration control component and a shell as described above, wherein the self-restoration control component is arranged in the shell.

[0131] The battery oven with the self-restoration control component can quickly respond to temperature changes, ensuring that the battery oven operates at the most suitable temperature, which not only improves production efficiency but also prolongs the service life of the battery oven.

[0132] Specifically, the bracket 100 is installed at a suitable position of the battery oven to ensure the stability and reliability of the bracket 100. The self-restoration fuse structure 200 can be detachably connected to the bracket 100, which facilitates installation and maintenance and ensures that components such as the self-restoration fuse structure 200 can be quickly replaced when necessary, such as when the self-restoration fuse structure 200 reaches the end of its service life. The self-restoration fuse structure 200 is indirectly electrically connected to the heating circuit through the connection with the bracket 100.

[0133] The self-restoration fuse structure 200 functions to sense temperature changes inside the battery oven and automatically open or close the circuit accordingly. This automated response mechanism is crucial for protecting the battery oven from overheating damage. At the same time, the self-restoration fuse structure 200 also ensures that the battery oven operates within a safe temperature range, thereby maintaining the normal working state of the oven and prolonging its service life.

[0134] The use of the self-recovery control component reduces maintenance costs, and does not need to be checked and replaced regularly, thereby reducing the long-term operation cost of the corresponding equipment. The self-recovery control component can quickly respond to temperature changes, ensuring that the battery oven operates at the most suitable temperature, not only improving production efficiency, but also prolonging the service life of the battery oven.
