[0024] In related technologies, electrode roller pressing ovens are generally distributed in layout, for example, composed of multiple independent structural units. These independent structural units need to be arranged sequentially along the electrode conveying direction. This layout not only occupies a large factory area, but also, because each independent structural unit is designed as a separate frame, the complexity of equipment installation and maintenance, as well as the manufacturing cost, are high. To address the above problems, embodiments of this application provide an oven device that can reduce the floor space required, lower the complexity of installation and maintenance, and reduce manufacturing costs.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the electrode transport path of the oven apparatus shown in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the oven apparatus shown in the embodiments of this application.

[0027] See Figure 1 and Figure 2 This application provides an oven apparatus 100, which includes an inlet 111, an outlet 112, and an electrode transfer path located between the inlet 111 and the outlet 112. An oven assembly 110 is arranged along the electrode transfer path. The electrode transfer path includes a first transfer path 101 located between the inlet 111 and the oven assembly 110, and a second transfer path 102 located between the oven assembly 110 and the outlet 112. At least a portion of the first transfer path 101 and the second transfer path 102 are arranged along the height direction of the oven apparatus 100.

[0028] In the technical solution of this application, at least part of the first and second transmission paths of the oven device are arranged along the height direction. While ensuring the heating treatment time of the electrode in the oven assembly, the optimized distribution of the up and down paths achieves a compact structure, significantly reducing the overall projected area of ​​the device and the floor space occupied. This makes the electrode transmission more stable and reduces the complexity of installation and maintenance as well as manufacturing costs.

[0029] In some embodiments, the oven apparatus 100 further includes a frame 1101, which includes a first mounting area and a second mounting area, arranged along the height direction of the frame 1101; wherein, the first mounting area is located at the bottom of the second mounting area, and the first mounting area is used to mount the oven assembly 110, with the inlet 111 and the outlet 112 located in the second mounting area.

[0030] In this embodiment, the frame 1101 refers to the supporting structure that carries the various components of the equipment, specifically a frame formed by connecting columns and beams. The electrode transfer path refers to the movement trajectory of the electrode 200 inside the frame 1101. The oven assembly 110 refers to the passage for the electrode 200 to be heated, specifically located on both sides of the bottom of the frame 1101. The first transfer path 101 causes the electrode to move vertically upward from the inlet 111 to the oven assembly 110, and the second transfer path 102 causes the electrode to fold back inside the oven assembly 110 and then move vertically downward from the oven assembly 110 to the outlet 112. After the electrode 200 enters from the feed port 111 at the bottom of the frame 1101, it moves upward along the first transmission path 101 to the oven assembly 110 to complete the heating treatment. The electrode 200 is then turned at the top of the oven assembly 110 by two laterally spaced turning rollers 1105 and moves downward along the second transmission path 102 to the discharge port 112.

[0031] The technical solution of this application integrates the inlet 111, outlet 112 and oven assembly 110 into the same frame 1101, reducing the number of structural units. This not only improves the installation accuracy and makes the electrode transfer more stable, but also reduces the complexity of installation and maintenance and manufacturing costs.

[0032] In some embodiments, a threading assembly, a tension control assembly, and an electrode cooling assembly are mounted on the frame 1101. These components at least partially overlap with the oven assembly 110 in the longitudinal direction. The threading assembly guides the electrode into the electrode transport path, the tension control assembly adjusts the transport tension of the electrode during transport, and the electrode cooling assembly cools the electrode after heating by the heating assembly to a predetermined temperature. In this embodiment, the overlapping projection refers to a partial overlap in the vertical spatial layout of the components. For example, the threading assembly, cooling assembly, and oven assembly 110 are arranged in a longitudinally overlapping manner, thereby reducing the horizontal footprint through longitudinal space reuse while maintaining the independent function of each component. Specifically, the frame 1101 is divided into upper and lower functional areas. The upper area houses the oven assembly 110, and the lower area houses the inlet 111 and outlet 112. The electrode transport path is designed to form a first transport path 101 between the inlet 111 and the oven assembly 110, and a second transport path 102 between the oven assembly 110 and the outlet 112. The threading assembly guides the electrode from the inlet 111 into the first transport path 101. The tension control assembly adjusts the electrode tension on the first transport path 101. After the oven assembly 110 completes heating, the electrode descends along the second transport path 102 to the electrode cooling assembly for cooling. The overlapping layout of the components in the longitudinal projection makes the equipment form a compact structure in the vertical direction.

[0033] In related technologies, the oven assembly 100 uses three independent frames to support the receiving platform 130, the oven assembly 110, and the cooling assembly, arranged horizontally, which increases the overall length of the equipment and results in inconsistent installation references. This application integrates all functional components onto a single frame 1101 and adopts a longitudinally projected overlapping layout, consolidating the three horizontally arranged independent frames in the related technologies into a vertically multi-layered structure, thereby effectively reducing the equipment's footprint. Simultaneously, the shared frame 1101 for multiple components avoids reference errors during assembly of multiple frames 1101, ensuring the straightness and parallelism of the electrode transport path.

[0034] Furthermore, the threading assembly is located at the bottom of the oven assembly 110 and adjacent to the inlet 111. The threading assembly is used to guide the electrode sheet from the inlet 111 into the electrode sheet transport path. Specifically, the threading assembly refers to the mechanism for guiding the electrode sheet 200 into the electrode sheet transport path, including a threading drive 120 and a threading rod (not shown). The threading drive 120 can be driven by a motor or linear module, or it can be driven manually. The threading rod is a rigid component used to fix the end of the electrode sheet, which can be implemented as a metal rod. Its function is to fix the end of the electrode sheet material for traction. When the electrode sheet enters from the inlet 111, the front end of the electrode sheet 200 is fixed to the threading rod, and the threading rod pulls the electrode sheet 200 upward along the first transport path 101 to the inlet of the oven assembly 110.

[0035] See also Figure 1 and Figure 2 Specifically, the oven apparatus 100 in this embodiment further includes a receiving platform 130, which is used to connect electrode strips from different batches or those that have broken. A threading drive 120 is located on the inlet side of the receiving platform 130. The receiving platform 130 includes a receiving drive and a pressing member connected to the receiving drive. The receiving drive drives the pressing member to a first height or a second height, where the first height is greater than the second height. At the second height, a space is formed at the bottom of the pressing member for the threading rod to pass through. The receiving platform 130 uses a two-stage cylinder control. In the belt-guiding mode, the pressing member rises to the first height, allowing the threading rod to pass through. In the non-belt-guiding mode, the pressing member only uses a single-stage cylinder for lifting and lowering to prevent accidental finger insertion and injury. The two-stage cylinder control refers to using a cylinder drive device with two-stage stroke adjustment functions. This can be achieved by setting two independent air paths or a staged air supply method, used to control the lifting and lowering stroke of the pressing member in both belt-guiding and non-belt-guiding modes. The lead-in mode refers to the operation stage where the device guides the electrode into the first transmission path 101 using the threading rod. In lead-in mode, the two-stage cylinder receives a control signal and drives the pressing component to rise to the first height. At this time, sufficient space is formed between the bottom of the pressing component and the receiving platform 130 for the threading rod to carry the electrode through. In non-lead-in mode, the cylinder only initiates the first stroke to raise the pressing component to the second height. At this time, the gap between the bottom of the pressing component and the receiving platform 130 is limited to a size too small to fit a finger, thus creating a physical barrier during the receiving operation. Through the linkage control of mode switching and cylinder stroke, both the operational efficiency of the threading stage and the safety hazards caused by accidental lifting or lowering of the pressing component during normal operation are ensured.

[0036] In some embodiments, the tension control component is located at the bottom of the oven assembly 110 and adjacent to the feed inlet 111. The tension control component is used to control the electrode transmission tension of the electrode transmission path. The tension control assembly includes a tension detection roller 140, a swing roller 150, and a traction roller 160. The tension detection roller 140 is located on the outlet side of the receiving platform 130 and is used to contact the electrode sheet to detect the transmission tension. The swing roller 150 swings perpendicular to the electrode sheet conveying plane and is used to adjust the tension of the electrode sheet when swinging. The traction roller 160 is arranged on both sides of the swing roller 150 and is used to guide the transmission direction of the electrode sheet. The two traction rollers 160 on both sides of the swing roller 150 are spaced apart along the height direction of the frame 1101, and the swing roller 150 is located on the side of the interval between the two traction rollers 160. One traction roller 160 is used to guide the electrode sheet output from the tension detection roller 140 to the swing roller 150, and the other traction roller 160 is used to guide the electrode sheet output from the swing roller 150 longitudinally to the oven assembly 110. When the swing roller 150 swings, it adjusts the displacement of the electrode sheet between the two traction rollers 160 along the thickness direction to adjust the tension value of the electrode sheet.

[0037] The tension detection roller 140 detects tension data by generating deformation through contact with the electrode surface. The swing roller 150 is a guide roller that can swing around a set axis. Specifically, it can be implemented using a servo motor-driven swing arm structure, which generates tension adjustment by changing the displacement of the electrode in the thickness direction. Since the swing direction of the swing roller 150 is perpendicular to the conveying plane, its swing amplitude directly changes the displacement of the electrode in the thickness direction, thus generating tension compensation or tension release. After the electrode is output from the receiving platform 130, it first passes through the tension detection roller 140 to obtain real-time tension data. The electrode is then guided to the swing roller 150 by the first traction roller 160. The swing roller 150 swings and adjusts according to the tension data feedback, and then the electrode is introduced into the drying oven assembly 110 by the second traction roller 160.

[0038] See also Figure 1 and Figure 2Furthermore, the oven assembly 110 of this application also includes an insulated chamber, which can be made of stainless steel. The insulated chamber contains an electrode heating channel, which is the space through which the electrode passes. The chamber wall has an insulation layer, which can be an aerogel filling layer. This material has a low thermal conductivity to prevent heat loss. The bottom of the insulated chamber has an inlet for introducing the electrode before heating and an outlet for exporting the electrode after heating. After the electrode enters the insulated chamber from the bottom inlet along the first transmission path 101, it passes through the heating channel. The heat source of the heating channel directly acts on the surface of the electrode, rapidly increasing the material temperature to release internal stress. After heating, the electrode folds back at the top of the insulated chamber and is exported through the outlet along the second transmission path 102. In some embodiments, the heating channel is "n"-shaped. The "n"-shaped path can extend the residence time of the electrode in the high-temperature region of the heating channel, ensuring the heating effect of the electrode.

[0039] In some embodiments, the oven assembly 110 further includes multiple infrared heating modules 1102, a pressure relief vent, an exhaust fan 1103, a cooling air filter 1104, a temperature detection device, and a differential pressure detection device. The multiple infrared heating modules 1102 are located on both sides of the heating channel, rapidly heating the electrode plates through infrared radiation, thus increasing the stress release speed of the electrode plates. The pressure relief vent is located at the top of the insulation chamber and automatically opens to release pressure when the internal pressure is abnormal. The exhaust fan 1103 is a forced ventilation device installed at the top of the insulation chamber, specifically a centrifugal fan, which continuously exhausts high-temperature gas from inside the insulation chamber, maintaining the pressure difference balance between the inside and outside of the insulation chamber. The differential pressure detection device is a pressure sensor that monitors changes in gas pressure. The cooling air filter is used to purify the air entering the insulation chamber, triggering a maintenance prompt when the pressure difference between the inlet and outlet exceeds a set threshold.

[0040] Specifically, pressure sensors can be installed at the inlet, outlet 112, and top exhaust duct of the oven unit 100. Temperature detection devices can include multiple temperature sensors arranged near the heating module 1102. When a local temperature exceeds a safety threshold or abnormal pressure fluctuations are detected, the control system triggers an alarm and adjusts the speed of the exhaust fan 1103. The exhaust fan 1103 utilizes the natural upward movement of hot air to achieve efficient exhaust. The pressure relief vent opens preferentially during sudden pressure increases to prevent damage to the insulated enclosure structure. The cooling air filter 1104 monitors the pressure drop across the filter element in real time using a differential pressure detector. When the pressure difference exceeds a set range, a maintenance warning signal is issued, allowing operators to quickly locate and replace the side-mounted filter element.

[0041] The technical solution of this application enables real-time and accurate monitoring of the internal pressure and temperature of the oven, effectively preventing operational accidents caused by local overheating or abnormal negative pressure; the synergistic effect of the exhaust fan 1103 at the top of the insulated box and the explosion vent ensures the rapid discharge of high-temperature gas to release the pressure inside the insulated box; the coordinated control of the cooling air filter device and the differential pressure detection device significantly improves maintenance efficiency and avoids the decrease in cooling efficiency caused by filter blockage.

[0042] Furthermore, the electrode cooling assembly of this application is located at the bottom of the oven assembly 110 and adjacent to the discharge port 112, and is used to cool the electrode after the oven assembly 110 is heated. The electrode cooling assembly includes a cooling roller 172 and a cooling traction roller 170. The cooling surface of the cooling roller 172 is used to contact the electrode 200. The cooling traction roller 170 is located downstream of the cooling roller 172. The cooling traction roller cooperates with the rubber roller 171 to draw the cooled electrode 200 out of the cooling area. Finally, the electrode 200 is discharged from the discharge port 112 through the passing roller 173. The cooling roller 172 can be an air-cooled roller. The air-cooled roller exchanges heat with the electrode contact surface through the internal high-speed airflow, so that the heat of the electrode is quickly discharged.

[0043] In some embodiments, the cooling assembly includes a throttle valve and a temperature sensing assembly. The throttle valve is connected to the cooling medium inlet of the cooling roller. The temperature sensing assembly is signal-connected to the throttle valve. The temperature sensing assembly includes a first temperature sensor 1701 located near the outlet of the heat insulation box and a second temperature sensor 1702 located near the discharge port 112. The first temperature sensor 1701 is used to detect the temperature of the electrode after heating, and the second temperature sensor 1702 is used to detect the temperature of the electrode after cooling.

[0044] Specifically, a throttle valve is connected to the compressed air inlet pipe of the cooling roller 172. By changing the valve opening, the flow rate of gas entering the cooling roller 172 is controlled, thereby adjusting the cooling capacity. Specifically, when the electrode 200 enters the cooling roller 172 from the outlet of the insulation box, the first temperature sensor 1701 measures its initial temperature in real time, and this data is transmitted to the throttle valve control system. Based on the difference between the initial temperature and the preset target temperature, the system automatically adjusts the throttle valve opening to change the gas flow rate inside the cooling roller 172. When the cooled electrode 200 reaches the outlet 112, the second temperature sensor 1702 measures its surface temperature again and compares the measured temperature with the target temperature. If a deviation exists, the system dynamically corrects the throttle valve opening, forming a closed-loop control circuit combining feedforward and feedback, ensuring that the electrode remains within the target temperature range throughout continuous production, thus improving the stability and consistency of the electrode cooling quality.
