Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, specifically to an oven partition device, an oven, and a driving method. Background Technology

[0002] In the manufacturing process of solid-state batteries and lithium-ion batteries, the coated electrode sheets need to be continuously dried in multiple ovens to remove solvents and cure the coating. Because the electrode active materials and solid electrolytes are extremely sensitive to moisture and oxygen in the air, the entire drying process usually needs to be carried out in a closed environment filled with inert gas to prevent hydrolysis or oxidation reactions. Existing oven equipment typically consists of multiple sections connected sequentially. To facilitate maintenance and troubleshooting, partitions are usually installed at the oven's inlet, outlet, or between sections. In existing technologies, these partitions often employ a single-sided driven door structure, or use independent power sources to control the opening and closing of the upper and lower or left and right doors to achieve the opening or closing of the material passage.

[0003] However, in related technologies, when it is necessary to open the partition door for maintenance or operation, it is often difficult to ensure strict synchronization of the two relatively moving door panels during displacement, which can easily lead to door misalignment, jamming, or poor sealing. This asynchrony not only affects the normal opening and closing function of the partition door, but may also prevent the formation of an effective independent closed space when closed, causing the isolation operation of a single oven section to fail. This, in turn, disrupts the inert gas environment of the entire production line, prolongs the atmosphere recovery time after maintenance, and affects the continuity and stability of production.

[0010] In one embodiment, the linkage mechanism and the transmission component are provided on both sides of the first door panel and the second door panel; the drive mechanism is configured to synchronously drive the transmission components on both sides of the lateral side through the transmission components, so that the linkage mechanism on both sides of the lateral side operates synchronously.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] In the coating process of solid-state batteries, key materials such as electrode active materials and solid electrolytes are extremely sensitive to moisture and oxygen in the air. Contact with these substances can easily lead to hydrolysis or oxidation reactions, resulting in defects in the electrode coating. Therefore, the coating and drying process typically needs to be carried out in an inert gas protective environment. Existing oven structures are mostly long-channel continuous designs. When maintenance or repair is required on a section of the oven, it is often necessary to open the entire section or disconnect a large area. This disrupts the inert gas environment within the entire oven system, not only wasting protective gas but also requiring a considerable amount of time to re-establish a stable inert gas atmosphere after maintenance, severely impacting production efficiency.

[0026] To address the aforementioned issues, this application provides an oven partition device that enables synchronous linkage between the first and second door panels, ensuring consistency of movement and sealing reliability during the opening and closing of the first and second door panels. This avoids damage to the inert gas environment of the entire oven production line and reduces the time required for atmosphere restoration after maintenance.

[0027] Please see Figures 1 to 3 The oven partition device 100 provided in this application includes a first door panel 110 and a second door panel 120 that can be opened and closed relative to each other. When the first door panel 110 and the second door panel 120 are opened, a channel 1101 for material transfer is formed between them. At least one set of linkage mechanism includes a first traction member 121 and a pulley assembly. The first traction member 121 surrounds the pulley assembly to form a closed-loop path defined by the pulley assembly. The closed-loop path includes a first drive part 1211 that is driven to the first door panel 110 and a second drive part 1212 that is driven to the second door panel 120. A drive mechanism and a transmission member connected to the power output end of the drive mechanism are provided. The transmission member is connected to the first door panel 110 and / or the second door panel 120 and is used to drive the linkage mechanism to operate. When the first traction member moves along the closed-loop path, the first drive part 1211 and the second drive part 1212 drive the first door panel 110 and the second door panel 120 to move synchronously towards or away from each other.

[0028] The oven partition device 100 of this application includes a mounting frame for fixing to the oven. A first door panel 110 and a second door panel 120 are movably mounted on the mounting frame, forming a material transfer channel 1101 between them when open, and effectively isolating the internal space of the oven when closed.

[0029] The first traction member 121 of the linkage mechanism forms a closed-loop movement path between the pulley assemblies. For example, the first traction member 121 may be a continuous steel wire rope, guided by multiple pulleys to form a loop. These pulleys may be fixed to a mounting bracket to provide support and steering for the traction member. Specific portions of the closed-loop movement path (e.g., specific portions with opposite directions of operation) are defined as the first drive unit 1211 and the second drive unit 1212, which are respectively connected to the first door panel 110 and the second door panel 120.

[0030] When the linkage mechanism is running, the first drive unit 1211 and the second drive unit 1212 can drive the first door panel 110 and the second door panel 120 to move synchronously in the same or opposite directions. For example, if the first traction member 121 is driven to move in the forward direction, then the first drive unit 1211 and the second drive unit 1212 can drive the first door panel 110 to move in opposite directions respectively; if the first traction member 121 is driven to move in the reverse direction, then the first drive unit 1211 and the second drive unit 1212 can drive the first door panel 110 to move in the reverse direction respectively, thereby achieving synchronous opening and closing.

[0031] As another implementation method, the linkage mechanism can also adopt a gear and rack system, in which the rack is connected to the door panel, the gear drives the rack, and the synchronous movement of the two door panels is achieved through a common drive shaft.

[0032] For example, in a coating and drying production line, the oven is divided into multiple independent chambers, each of which needs to maintain a strictly inert gas environment. When a chamber on the production line (e.g., chamber B) needs equipment maintenance or repair, the conventional practice is to open the maintenance door of chamber B. This causes the inert gas inside chamber B to escape and may affect the atmosphere of adjacent chambers (e.g., chambers A and C), thus requiring a long time to restore the inert gas environment of the entire area.

[0033] To address this, this application proposes an oven partition device 100, which can be installed between oven B and oven A, and between oven B and oven C. Taking the partition door between oven B and oven C as an example, the partition door includes a mounting bracket, which is firmly fixed to the connection structure between oven B and oven C. A first door panel 110 and a second door panel 120 are movably mounted on the mounting bracket. Under normal production conditions, the first door panel 110 and the second door panel 120 are in the open state, forming a channel 1101 for continuous transmission of electrode materials, ensuring smooth production flow. At this time, the linkage mechanism is in a stationary state, and the first traction member 121 maintains its closed-loop movement path.

[0034] When maintenance is required on enclosure B, the operator will activate the partition door. The drive mechanism moves the first traction member 121 along its closed-loop path. Since the first drive unit 1211 is connected to the first door panel 110 and the second drive unit 1212 is connected to the second door panel 120, the movement of the first traction member 121 simultaneously acts on both door panels, causing them to gradually approach and eventually close, thus completely sealing the passage 1101 between enclosure B and enclosure C. This ensures physical isolation and atmosphere sealing between enclosure B and enclosure C is achieved in the shortest possible time.

[0035] The oven partition device 100 provided in this application achieves precise mechanical forced synchronous movement between the first door panel 110 and the second door panel 120 through a linkage mechanism composed of a first traction member 121 and a pulley assembly. This device utilizes the reverse linkage relationship between the first drive unit 1211 and the second drive unit 1212 on a closed-loop path to ensure that the two door panels maintain strict motion synchronization and directional certainty during opening and closing. This device can be installed between adjacent ovens on a continuous production line. When a certain oven requires maintenance, the drive mechanism can quickly drive the linkage mechanism through the transmission member, causing the first door panel 110 and the second door panel 120 to close synchronously, achieving physical and atmospheric isolation of that oven. This allows maintenance operations to be performed without affecting the normal production of other units, reducing atmosphere recovery time, overall line downtime, and energy consumption.

[0036] In some embodiments, a plurality of path limiting members 150 are also included, distributed in the area between the first driving part 1211 and the second driving part 1212, and arranged along a preset trajectory; after the first traction member passes through the plurality of path limiting members 150, it realizes the switching of the movement direction between the first driving part 1211 and the second driving part 1212.

[0037] Multiple path limiting elements 150 are centrally arranged in the area between the first drive unit 1211 and the second drive unit 1212. The first traction member passes through these path limiting elements 150, thereby completing the change of movement direction in its closed-loop path at the key section between the first drive unit 1211 and the second drive unit 1212. By setting the path limiting elements 150 in the aforementioned specific area, the movement trajectory of the traction member between the two drive units is effectively guided and constrained, so that the movement of the first drive unit 1211 can be reliably converted into the reverse movement of the second drive unit 1212 through this area. This not only ensures the strict symmetry and synchronization of the movement directions of the first door panel 110 and the second door panel 120, eliminating the risk of asynchronous movement, but also optimizes the path layout of the traction member, reduces interference with surrounding structures, makes the movement transmission of the entire linkage mechanism more precise and smooth, and contributes to the compactness of the device structure.

[0038] In some specific embodiments, the path limiting member 150 may be a guide ring, which is an annular or perforated structure used to guide and constrain the movement trajectory of the traction member. These guide rings may be made of wear-resistant materials, such as metals (e.g., stainless steel, aluminum alloy), with an inner diameter or aperture slightly larger than the outer diameter of the first traction member 121 to ensure smooth passage and effective constraint of the first traction member 121. The shape of the guide ring may be designed as circular, elliptical, or a shaped hole with specific guide grooves, depending on actual needs, to suit the type and motion characteristics of the first traction member 121.

[0039] In this application, multiple path limiting elements 150 work in conjunction with the pulley assembly to guide the movement of the first traction member 121. The pulley assembly provides support for the first traction member 121, while the guide rings provide additional path constraints between the pulley assemblies or in specific areas to enhance the overall guidance and constraint of the first traction member 121, preventing slackness, vibration, or derailment at or between the pulleys. Furthermore, the layout design of the guide rings diverts different parts of the first traction member 121 to two opposing sub-paths as it passes through them. These sub-paths correspond to the first drive unit 1211 and the second drive unit 1212 connected to the first door panel 110 and the second door panel 120, respectively. Since the first drive unit 1211 and the second drive unit 1212 are connected to the first door panel 110 and the second door panel 120, respectively, this stable guiding mechanism ensures that the first door panel 110 and the second door panel 120 can move synchronously and precisely in the same or opposite directions during the operation of the linkage mechanism. In this way, the operational stability of the linkage mechanism is significantly improved, and the movement trajectory of the door panel is no longer prone to deviation or incoordination, thereby ensuring the accuracy of the material transfer channel 1101 formed by the oven partition device 100 when it is in the open state and improving the reliability of the partition.

[0040] See Figure 2 In some embodiments, the number of path defining elements 150 is at least four, with the four path defining elements 150 distributed at the four vertices of the virtual quadrilateral A; the first traction element includes a first path segment and a second path segment, which respectively pass through the two diagonals of the virtual quadrilateral and run in opposite directions. When the first traction element 121 operates in a closed loop, the first path segment passes through the first drive unit 1211, and the second path segment passes through the second drive unit 1212.

[0041] It is worth noting that, in addition to the four path limiting components 150, fewer or more than four can be used, such as three or five path limiting components 150, or continuous guide grooves can be used to guide the traction component, depending on actual needs and space constraints.

[0042] In this embodiment, the virtual quadrilateral A refers to the geometric shape formed in space by the four path limiting members 150. This layout provides clear geometric constraints for the precise guidance of the first traction member 121. The arrangement along the two diagonals of the virtual quadrilateral means that the direction of the first and second path segments in space is consistent with the diagonal direction of the virtual quadrilateral. This diagonal layout effectively decomposes and transmits the traction force to the first door panel 110 and the second door panel 120 at their upper and lower positions. Simultaneously, the opposite direction of movement ensures that the first door panel 110 and the second door panel 120 can achieve relative movement, such as moving towards or away from each other, under the drive of the linkage mechanism, to complete the opening or closing of the channel 1101.

[0043] In one specific implementation, four guide rings can be provided on each of the lateral sides of the first door panel 110 and the second door panel 120, such as a first guide ring 151, a second guide ring 152, a third guide ring 153, and a fourth guide ring 154. These four guide rings can be arranged in a trapezoidal, staggered pattern, and their front-to-back direction can be... Figure 3 In the Y direction, the short sides (151, 152) of the trapezoid are located at the front of channel 1101, and the long sides (153, 154) are located at the rear of channel 1101, with both the long and short sides perpendicular to the direction of channel 1101. Furthermore, two guide wheels 1011 are provided on one side of the short side to guide the two path segments of the first traction member 121 to the four guide rings and to support the two sub-paths.

[0044] In this arrangement, the first drive unit 1211 can be parallel to one of the opposite sides of the trapezoid, while the second drive unit 1212 is parallel to the other opposite side of the trapezoid. The first traction member 121, such as a steel wire rope, can cross through these four guide rings, or after being guided by guide wheels, it can be wound into the pulley grooves of the first pulley group 131 130 and the second pulley group 132. This arrangement allows a steel wire rope to form a first path segment and a second path segment. In this way, the different positions of the steel wire rope during closed-loop movement can be accurately converted into the displacements of the first door panel 110 and the second door panel 120, ensuring the synchronicity and stability of the door panels during opening and closing.

[0045] In some embodiments, the mounting bracket includes a door back panel and side panels 102 disposed on both sides of the door back panel 101. Multiple path limiting members 150 are mounted on the side panels 102, and the side panels 102 intersect the door back panel 101 perpendicularly. The side panels 102, the first door panel 110, and the second door panel 120 are disposed on the front side of the door back panel 101. When the first door panel 110 and the second door panel 120 are in the closed state, they are in contact with the door back panel 101. When they are in the open state, they are away from the door back panel 101. With this arrangement, the first door panel 110 and the second door panel 120 will not interfere with the door back panel 101 during movement, and the door sealing performance can be improved through contact with the door back panel.

[0046] In some embodiments, a guiding mechanism is also included, comprising a first guiding portion for guiding the movement of the first door panel 110 and a second guiding portion for guiding the movement of the second door panel 120; the first and second guiding portions are inclined relative to the channel 1101 to constrain the movement trajectory of the first door panel 110 and the second door panel 120; the moving direction of the first driving portion 1211 is associated with the extending direction of the first guiding portion, and the moving direction of the second driving portion 1212 is associated with the extending direction of the second guiding portion.

[0047] In this embodiment, the first guide part and the second guide part can be slide rails 160 fixedly installed on the side plate 102. Specifically, the slide rail 160 corresponding to the first door body is parallel to the movement direction of the first drive part 1211, and the slide rail 160 corresponding to the second door panel 120 is parallel to the movement direction of the second drive part 1212. The slide rails 160 provide a clear guide path for the movement of the door panels. When the linkage mechanism drives the first door panel 110 and the second door panel 120 to move via the first drive part 1211 and the second drive part 1212 of the first traction member 121, the mating components on the door panels will move under the constraint of the slide rails 160. Due to the inclined arrangement of the slide rails 160, the movement trajectory of the door panels is naturally decomposed into a component perpendicular to the direction of the channel 1101 and a component parallel to the direction of the channel 1101. This composite motion mode allows the door panel to press downwards and simultaneously fit horizontally against the back panel of the door body when closed, forming a tighter seal with the oven opening and effectively preventing gas exchange between the inside and outside of the oven. When opened, it can be lifted upwards to form channel 1101, providing sufficient clearance for material transfer and preventing interference between the door panel and the back panel of the door body. The slide rail 160 of the first door panel 110 is parallel to the first drive unit 1211, and the slide rail 160 of the second door panel 120 is parallel to the second drive unit 1212. This ensures that the traction force of the linkage mechanism can be efficiently and smoothly converted into the movement of the first door panel 110 and the second door panel 120 along the preset trajectory, ensuring efficient transmission of traction force, reducing movement resistance, and preventing the door panels from deviating or jamming during movement.

[0048] In this embodiment, during the opening process, the first door panel 110 and the second door panel 120 first move outward a certain distance along the inclined direction of the slide rail 160 to disengage from the sealing surface of the door back panel, and then continue to move upward or downward to open the channel 1101; during the closing process, when the first door panel 110 and the second door panel 120 move to the closed position, the inclined component of the slide rail 160 generates a perpendicular pressing force, so that the first door panel 110 and the second door panel 120 are tightly pressed together between each other, thereby achieving reliable sealing and isolation.

[0049] In some embodiments, the first door panel 110 is equipped with a sealing element on the edge side opposite to the second door panel 120 and on the side opposite to the back panel of the door body. The sealing element may be a fluororubber strip. In addition, the first door panel 110 is provided with a partition door stop strip on the side opposite to the second door panel 120 to achieve buffering and limiting when the first door panel 110 approaches the second door panel 120.

[0050] The horizontal direction of this application can be Figure 1 In the X direction, in some embodiments, both the first door panel 110 and the second door panel 120 are provided with linkage mechanisms and transmission components on their lateral sides; the drive mechanism is configured to synchronously drive the transmission components on both lateral sides through the transmission components, so that the linkage mechanisms on both lateral sides operate synchronously. It also includes a third pulley group, the transmission component being a second traction component, which is connected to the second door panel 120 and, after passing through the third pulley group, is connected to the drive mechanism via transmission.

[0051] In this embodiment, the power output end of the drive mechanism (e.g., a combination of a servo motor and a reducer) is connected to a synchronous shaft, which extends laterally and is located above the first door panel 110 and the second door panel 120. On both sides of the first door panel 110 and the second door panel 120, an identical linkage mechanism and a second traction member serving as a transmission component are provided. One end of the second traction member on each side is connected to the top of the second door panel 120 (or the first door panel 110) on the same side, and the other end passes through a third pulley set located above it and is then connected to the drive mechanism or its synchronous shaft. When the drive mechanism is started, its power is precisely and equally transmitted simultaneously to the second traction members on both sides via the synchronous shaft or rigid linkage rod, thereby causing the transmission members on both sides to synchronously drive the linkage mechanisms on both sides at the same speed and stroke.

[0052] In this embodiment, the first door panel 110 and the second door panel 120 are arranged to open and close along the longitudinal (or height) direction. A set of linkage mechanisms and a second traction member 122 are provided on both the lateral sides of the first door panel 110 and the second door panel 120. The second traction members 122 on both lateral sides are driven synchronously with the drive mechanism, enabling the linkage mechanisms on both lateral sides to operate synchronously. By symmetrically arranging the linkage mechanisms and transmission members on both lateral sides and using a single drive mechanism for central synchronous drive, it is ensured that the first door panel 110 and the second door panel 120 experience balanced forces and consistent movement trajectories on both lateral sides during opening and closing. This effectively prevents problems such as skewing, jamming, or poor sealing caused by unilateral force or asynchrony during door panel movement.

[0053] In this embodiment, the drive mechanism drives the second door panel 120 (e.g., the lower door panel) to move upwards or downwards against its own weight and the weight of any possible counterweights via the second traction member 122. When the lower door panel moves, because it is connected to the first traction member 121 of the linkage mechanism, the first traction member 121 will move in a circular motion around the pulley. This circular motion of the first traction member 121 then pulls the upper door panel, which is connected to another part of the first traction member 121, thereby achieving synchronous linkage between the upper and lower door panels. This cooperative working mechanism enables the entire partition door system to achieve precise synchronous opening and closing of the two door panels under the action of a single drive source, improving operational efficiency and control precision.

[0054] In one specific implementation, the drive mechanism can employ a servo motor connected to a drum via a reducer. The second traction member 122 can be a high-strength steel wire rope, one end of which is fixed to the drum, and the other end is securely connected to the top edge of the second door panel 120 via a connector. A counterweight can be installed at the bottom of the second door panel 120 to provide a stable downward traction force, ensuring the stability of the passage 1101 when the door panel is open.

[0055] See also Figure 1 and Figure 3 In some embodiments, the pulley assembly includes a first pulley group 130 and a second pulley group 140, which are respectively disposed on the outer side of the first door panel 110 and the second door panel 120 in the opening and closing direction (or longitudinal direction); the first traction member 121 passes around the first pulley group 130 to form a first drive part 1211, and after being turned by multiple path limiting members 150, passes around the second pulley group 140 to form a second drive part 1212.

[0056] The first pulley group 130 and the second pulley group 140 respectively undertake the traction tasks of the first door panel 110 and the second door panel 120, ensuring that they can move independently or in coordination. The first pulley group 130 and the second pulley group 140 can be composed of multiple fixed pulleys (e.g., the first pulley 131 and the second pulley 132), and the force can be amplified or the stroke adjusted through the principle of the pulley group. Alternatively, the first pulley group 130 and the second pulley group 140 can also be one or more independent groups of pulleys, which can be mounted on fixed axles, or some pulleys can move with the door panels.

[0057] The first traction member 121 bypasses the first pulley block 130 and the second pulley block 140 to form a drive section that connects to the first door panel 110 and the second door panel 120, respectively. This design allows a single traction member to drive both door panels simultaneously, simplifying the transmission structure.

[0058] In some embodiments, the oven partition device 100 further includes sliding connectors fixedly disposed on the lateral sides of the first door panel 110 and the second door panel 120. The sliding connectors are provided with at least two cam followers, which are spaced apart along the extension direction of the slide rail 160 and limited to sliding within the slide rail 160. Specifically, the first door panel 110 has two first sliding connectors 111 on its lateral sides, which are slidably connected to the upper slide rails 160 on its lateral sides, respectively. The second door panel 120 has two second sliding connectors 123 on its lateral sides, which are slidably connected to the lower slide rails 160 on its lateral sides, respectively.

[0059] In one specific implementation, the sliding connector can be an L-shaped connecting plate, one side of which is firmly fixed to the lateral side of the first door panel 110 and the second door panel 120 by bolts. Two cam followers can be installed on the other side of the L-shaped connecting plate away from the door panel. These two cam followers are spaced apart along the extension direction of the slide rail 160. The spaced cam followers provide stable multi-point support, effectively suppressing the tilting and swaying of the door panel during movement, and improving the overall operational stability.

[0060] In some embodiments, the drive mechanism is located on top of the first door panel 110 and the second door panel 120. One end of the second traction member 122 is connected to the second door panel 120 at the bottom longitudinal direction, and the other end passes around the third pulley group 170 and is connected to the drive mechanism for transmission. The third pulley group 170 is a device composed of one or more pulleys, whose main function is to guide the movement path of the second traction member 122, change the direction of force, and reduce frictional resistance during transmission. This component can be one or more guide pulleys fixed at the top.

[0061] See Figure 4 and Figure 5In some embodiments, the oven partition device 100 further includes a drive connection assembly. The first door panel 110 and the second door panel 120 are respectively connected to the first drive unit 1211 and the second drive unit 1212 through corresponding drive connection assemblies, so that when the first drive unit 1211 and the second drive unit 1212 move, the first door panel 110 and the second door panel 120 can be driven to move through the corresponding drive connection assemblies.

[0062] Specifically, the drive connection assembly includes two sets of upper drive connectors 1111 respectively disposed at both ends of the first door panel 110 in the horizontal direction, and two sets of lower drive connectors 1112 respectively disposed at both ends of the second door panel 120 in the horizontal direction. The two sets of upper drive connectors 1111 are respectively connected between the two first drive units 1211 at both ends of the horizontal direction and the first door panel 110, and the two sets of lower drive connectors 1112 are respectively connected between the two second drive units 1212 at both ends of the horizontal direction and the second door panel 120. Thus, the two first drive units 1211 jointly drive the first door panel 110 through their corresponding upper drive connectors 1111, and the two second drive units 1212 jointly drive the second door panel 120 through their corresponding lower drive connectors 1112.

[0063] The oven partition device of this application has been described above. Accordingly, this application also provides an oven, which includes multiple sections of the oven body, and an oven partition device 100 as described in the above embodiment is provided between adjacent sections.

[0064] In this context, "multi-section chambers" refers to a structure of multiple independent drying chambers arranged sequentially along the material transport direction. These chambers together form a complete drying space for accommodating and processing continuously transported materials such as solid-state battery electrodes. Each chamber can be considered an independent temperature and atmosphere control unit, with different temperature gradients or gas flow rates set internally according to process requirements. At the connection points of the multi-section chambers, i.e., between the discharge port of the preceding chamber and the inlet of the following chamber, partition doors are installed to selectively connect or block physical space. This layout logically divides the entire production line into multiple independent sections, and the opening operation of any section is restricted to that section without affecting adjacent sections.

[0065] The oven partition device 100 can refer to an opening and closing device installed at the junction of two adjacent oven sections, and its specific structure and working principle are as defined in any of the embodiments described above. For example, the partition device may include a mounting frame fixed to the oven frame, a first door panel 110 and a second door panel 120 that can move synchronously in opposite directions on the frame, and a winding part and a pulley guide system for driving the door panel movement. When the oven is in normal operation, the partition door is in the closed position, and the first door panel 110 and the second door panel 120 abut against each other or are close together, completely isolating the two adjacent oven sections, so that each oven section forms an independent sealed space, thereby maintaining its own independent inert gas atmosphere. When maintenance is required on a certain oven section, the operator only needs to control the partition doors at both ends of that oven section to open, so that the first door panel 110 and the second door panel 120 are moved away from each other to form a channel 1101 for material to pass through, while the partition doors between adjacent oven sections remain closed to ensure that the atmosphere in other areas is not disturbed.

[0066] Specifically, in the multi-section oven system, the aforementioned oven partition device 100 is embedded at the connection interface between every two adjacent sections. During production, all partition doors are closed, dividing the long oven into several independent short chambers. If a section malfunctions or requires cleaning, the control system drives the actuators of the two oven partition devices 100 at the inlet and outlet ends of that section, causing the traction components to retract and open. The first door panel 110 and the second door panel 120 are guided to slide open synchronously via a pulley guide system, exposing the internal space of that section. Because the partition doors of adjacent sections remain closed, outside air cannot enter the unopened chamber, and the inert gas inside the unopened chamber will not leak out in large quantities. After maintenance, the partition doors are closed again, quickly restoring the sealing of that section. Production can then resume with only a small-scale atmosphere replacement of that section, eliminating the need for prolonged gas replacement of the entire production line.

[0067] As a preferred embodiment, the solution of this application is implemented as follows: Assume the oven consists of five sections connected in series, labeled as section A, section B, section C, section D, and section E. Oven partition devices 100 as described above are installed at the connections between A and B, B and C, C and D, and D and E. When section C needs maintenance, the two partition doors located at the BC and CD interfaces are opened simultaneously. At this time, section C is connected to the outside or adjacent sections, while the partition doors between sections A, B, D, and E remain closed. In this way, sections A and B, as well as sections D and E, maintain a high-purity inert gas environment, allowing production activities to continue in these unaffected sections, or at least ensuring atmospheric stability in these sections. After maintenance, the partition doors at BC and CD are closed, and only the interior of section C is purged with nitrogen, allowing it to quickly return to its working state.

[0068] This application also provides a driving method for the oven partition device 100 as described in the above embodiment.

[0069] See Figure 1 and Figure 6 The method includes the following steps: S110. A closed-loop moving path is formed for the first traction member, and a first drive unit 1211 that is connected to the first door panel 110 and a second drive unit 1212 that is connected to the second door panel 120 are defined on the closed-loop moving path.

[0070] In this step, the closed-loop movement path is formed in the following way: A set of pulley assemblies is arranged on the mounting frame of the oven partition device 100. This assembly includes multiple pulleys fixed at specific spatial positions. The first traction member is sequentially wound around these pulleys to form a continuous, end-to-end circular path. In this closed-loop path, two straight segments or specific sections with different directions of movement are selected and defined as the first drive unit 1211 and the second drive unit 1212, respectively. Then, the first drive unit 1211 is connected to one lateral end of the first door panel 110, and the second drive unit 1212 is connected to the other lateral end of the second door panel 120 through a drive connection assembly, thereby establishing a transmission relationship between the moving part of the traction member and the movement of the door panel.

[0071] S120, drive the first traction component to move along the closed-loop moving path.

[0072] In this step, a drive mechanism fixed to the top or side of the door is activated. The power output end of this drive mechanism is connected to a transmission component. This transmission component is connected to either the first door panel 110 or the second door panel 120. When the drive mechanism is activated, its output power acts directly on one of the door panels through the transmission component, causing it to begin moving. The movement of this door panel, through the connected drive connection assembly, pulls the corresponding drive unit on the first traction component, thereby driving the entire first traction component to begin cyclically moving along its predetermined closed-loop path.

[0073] S130, through the linkage of the first drive unit 1211 and the second drive unit 1212 during the movement process, the first door panel 110 and the second door panel 120 are synchronously driven to perform opening and closing movements in opposite directions or in opposite directions.

[0074] When the first traction member begins to move under the drive of step S120, the first driving part 1211 and the second driving part 1212, which are predefined on its closed-loop path, immediately begin to move. Since the positions and directions of these two driving parts in the closed-loop path are designed to always be opposite, and they are rigidly connected to the first door panel 110 and the second door panel 120 respectively through driving connection assemblies, the movement of the first driving part 1211 is directly converted into a pulling or pushing force on the first door panel 110 through its connection assembly, while the opposite movement of the second driving part 1212 is synchronously converted into a pulling or pushing force on the second door panel 120. Under this linkage mechanism, the first door panel 110 and the second door panel 120 move synchronously under the constraints of their respective guide mechanisms until they reach the predetermined opening / closing position.

[0075] The solution provided in this embodiment achieves strict synchronization and directional symmetry of the movement of the first door panel 110 and the second door panel 120 through the movement of a single traction member in a closed-loop path. Its structured linkage mechanism not only ensures high repeatability and reliability of the opening and closing action, but also enables the door panel to tightly press the sealing surface when closed, significantly improving the sealing performance of the partition device in the closed state.

[0076] In some embodiments, the method further includes: constraining the movement trajectories of the first door panel 110 and the second door panel 120 respectively by means of a first guide portion and a second guide portion that are inclined relative to the vertical direction; wherein the moving direction of the first drive portion 1211 is associated with the extending direction of the first guide portion, and the moving direction of the second drive portion 1212 is associated with the extending direction of the second guide portion.

[0077] In this embodiment, the first guide portion and the second guide portion can each be two guide rails with a fixed inclination angle relative to the vertical direction. These guide rails are fixedly mounted on the mounting frame of the oven partition device 100, and their inclination direction is consistent with the required opening and closing trajectory of the door panel. The first door panel 110 and the second door panel 120 are slidably engaged with the first guide portion and the second guide portion respectively via sliding connectors. During operation of the linkage mechanism, the movement direction of the first drive portion 1211 and the second drive portion 1212 in the closed-loop path is designed to remain parallel to the inclination extension direction of the corresponding guide portion. Specifically, when the first drive portion 1211 moves along the first segment of the closed-loop path, its movement direction is consistent with the inclination direction of the first guide portion, thereby pulling the first door panel 110 along the inclination track of the first guide portion via the connector; similarly, the second drive portion 1212 moves along the second segment in the opposite direction, its direction being consistent with the inclination direction of the second guide portion, driving the second door panel 120 along its track.

[0078] In this embodiment, the opening and closing motion of the first door panel 110 and the second door panel 120 is decomposed into a composite motion with lateral and longitudinal components. During the closing process, this design generates a pressing force perpendicular to the sealing surface when the door panel contacts the sealing surface, effectively enhancing the sealing reliability in the closed state and effectively preventing gas leakage and heat loss. At the same time, the inclined guide provides precise and stable motion constraints for the door panel, avoiding shaking, jamming, or trajectory deviation during operation, ensuring long-term operational stability and repeatability accuracy.
