Side door opening system and battery drying furnace

Abstract

The utility model relates to a side door opening system and a battery drying furnace. The side door opening system comprises a fixed guide rail and a supporting mechanism. When sealing the drying bin, the furnace door is supported by the first movable guide rail corresponding to the supporting mechanism, and the second movable guide rail corresponding to the supporting mechanism is in butt joint with the fixed guide rail. At the moment, the notch of the fixed guide rail is filled up by the second movable guide rail, so that other furnace doors can smoothly slide along the fixed guide rail to realize door closing or door opening. Moreover, as the first movable guide rail can float along the width direction relative to the second movable guide rail, when the positions of the first movable guide rail and the supported furnace door are changed, the relative position between the second movable guide rail and the fixed guide rail can be kept unchanged, so that the second movable guide rail and the fixed guide rail are kept high in alignment degree; and the furnace door is prevented from being blocked when passing through the joint. Therefore, the side door opening system and the battery drying furnace enable the side door opening to be more convenient.

[0035] See also Figure 1 and Figure 2 The present invention provides a battery drying oven 10 and a side-opening door system 100. The battery drying oven 10 includes a side-opening door system 100, an oven body 200, and an oven door 300.

[0036] The furnace body 200 has at least two drying chambers (not shown in the figure), which are used to accommodate battery cells to be dried. The furnace body 200 can directly heat the drying chamber under normal pressure, or it can first evacuate the drying chamber and heat the drying chamber under negative pressure. Each drying chamber of the furnace body 200 has an opening, and the openings of at least two drying chambers face the same side. There are at least two furnace doors 300, which are used to close the openings of at least two drying chambers respectively. The opening edge of the drying chamber is generally also provided with a sealing ring (not shown in the figure), which can cooperate with the furnace door 300 to better seal the drying chamber.

[0037] The oven door 300 is mounted on the side-opening door system 100. The side-opening door system 100 can drive the oven door 300 to move in a direction perpendicular to the drying chamber opening plane (i.e., the front-to-back direction), thereby moving the oven door 300 away from or closer to the drying chamber opening. It can also drive the oven door 300 to slide in a direction parallel to the drying chamber opening plane (i.e., the left-to-right direction), thereby performing side-to-side door opening and closing operations. The oven door 300 is generally provided with support rollers 310 for cooperating with the side-opening door system 100 to facilitate the sliding of the oven door 300.

[0038] Please also refer to Figure 3In one embodiment of the present invention, a side-opening door system 100 includes a fixed guide rail 110 and a support mechanism 120 .

[0039] The fixed rail 110 has a discontinuous structure, with at least two spaced-apart notches (not shown) formed along its extension. The fixed rail 110 is positioned along the edge of the furnace body 200, specifically the bottom edge in this embodiment. The support mechanisms 120 are positioned corresponding to the notches, and the number of notches on the fixed rail 110 is determined by the number of support mechanisms 120. For example, if four support mechanisms 120 are provided, four notches will be formed on the fixed rail 110.

[0040] The support mechanism 120 is used to support the furnace door 300 and can drive the furnace door 300 to move in a direction perpendicular to the opening plane of the drying bin, that is, in the aforementioned front-to-back direction, so that the furnace door 300 moves closer to or further away from the corresponding drying bin. When the furnace door 300 approaches and abuts against the sealing ring at the edge of the drying bin opening, the corresponding drying bin can be closed; and when the furnace door 300 moves away and separates from the edge of the drying bin opening, the corresponding drying bin can be opened. Among them, one furnace door 300 can be supported and driven by multiple support mechanisms 120, or it can be supported and driven by a single support mechanism 120. Specifically in the present embodiment, each furnace door 300 is supported by two support mechanisms 120, and there are two furnace doors 300 in total. Therefore, the above-mentioned side-opening door system 100 is provided with a total of four support mechanisms 120.

[0041] Please also refer to Figure 4 and Figure 5 The supporting mechanism 120 includes a first movable guide rail 121 , a second movable guide rail 122 , a driving member 123 and a floating assembly 124 .

[0042] The first movable rail 121 and the second movable rail 122 are arranged side by side and connected by a floating assembly 124. The lengths of the first and second movable rails 121, 122 are approximately the same as the lengths of their corresponding notches, and their widths are approximately the same as the width of the fixed rail 110. Furthermore, the first movable rail 121 is located on the side of the second movable rail 122 that faces the drying chamber. Specifically, the first movable rail 121 is located inside the support mechanism 120, while the second movable rail 122 is located outside the support mechanism 120.

[0043] The first movable rail 121 and the second movable rail 122 are designed as separate components and are not fixedly connected. A floating assembly 124 enables the first movable rail 121 to float relative to the second movable rail 122 in the width direction. This width direction coincides with the width direction of the fixed rail 110, i.e., the front-to-back direction described above. In other words, while the second movable rail 122 is fixed in position, the first movable rail 121 can still float in the front-to-back direction.

[0044] The driving member 123 can drive the first movable guide rail 121 and the second movable guide rail 122 to slide back and forth in the corresponding gap along the width direction of the fixed guide rail 110, so that the first movable guide rail 121 and the second movable guide rail 122 alternately dock with the fixed guide rail 110. When the first movable guide rail 121 docks with the fixed guide rail 110, the two ends of the first movable guide rail 121 are aligned with the fixed guide rails 110 at both ends of the gap, and the two form a continuous track, and the second movable rail 121 exits from the side of the gap facing away from the drying chamber (see Figure 7 Similarly, when the second movable guide rail 122 is docked with the fixed guide rail 110, the two ends of the second movable guide rail 122 are aligned with the fixed guide rails 110 at both ends of the gap, and the two form a continuous track, and the first movable guide rail 121 exits from the gap toward one side of the drying chamber (see Figure 6 ).

[0045] The driving member 123 can be a pneumatic cylinder, an electric cylinder, etc., and can be connected to any one of the first movable guide rail 121 and the second movable guide rail 122, or can drive the first movable guide rail 121 and the second movable guide rail 122 to slide synchronously through an intermediate transmission structure (not shown).

[0046] During the process of closing the oven door 300, the driving member 123 of the corresponding support mechanism 120 first drives the first movable guide rail 121 to dock with the fixed guide rail 110; then the oven door 300 is slid along the fixed guide rail 110 to the first movable guide rail 121, so that the oven door 300 is in the closed position; the driving member 123 then drives the first movable guide rail 121 and the oven door 300 supported by it to move toward the drying chamber until the second movable guide rail 122 of the corresponding support mechanism 120 docks with the fixed guide rail 110, and the oven door 300 and the sealing ring of the opening edge of the drying chamber will also abut at this time, thereby realizing the door closing operation and sealing the drying chamber. At this time, the state of the support mechanism 120 is as follows: Figure 6 shown.

[0047] As can be seen, when the oven door 300 is closed, it is supported by the first movable guide rail 121 of the corresponding support mechanism 120, while the second movable guide rail 122 of the corresponding support mechanism 120 is connected to the fixed guide rail 110. At this time, the gap in the fixed guide rail 110 is filled by the second movable guide rail 122, and the two together form a continuous track, so the rest of the oven door 300 can slide smoothly along the fixed guide rail 110 to achieve the door closing or opening operation.

[0048] During the process of opening the oven door 300, the driving member 123 of the corresponding support mechanism 120 first drives the first movable guide rail 121 away from the opening of the drying chamber until the first movable guide rail 121 moves to dock with the fixed guide rail 110, and the oven door 300 is separated from the opening edge of the corresponding drying chamber; at this time, the state of the support mechanism 120 is as follows: Figure 7As shown, the fixed guide rail 110 and the first movable guide rail 121 together form a continuous track, so that the oven door 300 can be slid from the first movable guide rail 121 to the fixed guide rail 110, and the oven door 300 can be slid along the fixed guide rail 110 to the door opening position to realize the door opening operation.

[0049] The side-opening door system 100 is typically installed at the bottom of the furnace body 200. Specifically, the fixed guide rails 110 are typically located along the bottom edge of the furnace body 200. This allows the side-opening door system 100 to support the furnace door 300 from the bottom up. Alternatively, another side-opening door system 100 can be installed at the top edge of the furnace body 200. In this way, two side-opening door systems 100 can support the furnace door 300 at its upper and lower ends, thereby improving the reliability of the support for the furnace door 300 and ensuring smoother opening and closing operations.

[0050] Please refer again Figure 3 In this embodiment, the side-opening door system 100 further includes a side-sliding drive mechanism 130, which is capable of driving the oven door 300 to slide along the fixed guide rail 110. The side-sliding drive mechanism 130 can use a servo motor-driven synchronous belt, a servo motor directly connected to a module, or a pneumatic cylinder to drive the oven door 300 to slide sideways, thereby automatically driving the oven door 300 to switch between an open position and a closed position.

[0051] The side-sliding drive mechanism 130 can always remain connected to the furnace door 300, or the driving end of the side-sliding drive mechanism 130 can be docked with the furnace door 300 after the furnace door 300 is separated from the opening edge of the drying chamber and the first movable guide rail 121 supporting the furnace door 300 is moved to dock with the fixed guide rail 110.

[0052] It should be noted that, in other embodiments, the side-sliding drive mechanism 130 may also be omitted, so that an operator manually pushes and pulls the furnace door 300 to make the furnace door 300 slide sideways along the fixed guide rail 110 .

[0053] As mentioned above, the drying chamber of the furnace body 200 can operate under both normal and negative pressure conditions. Under negative pressure, due to the significant pressure differential between the inside and outside of the furnace door 300, the furnace door 300 compresses the sealing ring more strongly than under normal pressure. Consequently, the furnace door 300 is positioned closer to the edge of the drying chamber opening than under normal pressure. This means that the position of the first movable guide rail 121 and the furnace door 300 it supports may vary under different operating conditions. Since the first movable guide rail 121 can float relative to the second movable guide rail 122 in the width direction, when the position of the first movable guide rail 121 and the supported furnace door 300 changes, the relative position between the second movable guide rail 122 and the fixed guide rail 110 can also remain unchanged, so that the second movable guide rail 122 and the fixed guide rail 110 always maintain a high degree of alignment, which can prevent the furnace door 300 from getting stuck when passing through the junction of the second movable guide rail 122 and the fixed guide rail 110, so that the furnace door 300 can slide sideways more smoothly and reduce damage to the support roller 310.

[0054] Specifically, in this embodiment, the floating assembly 124 can provide an elastic force, and the first movable guide rail 121 and the second movable guide rail 122 can be pressed against each other under the action of the elastic force.

[0055] Because the first movable rail 121 and the second movable rail 122 are closely aligned, in the initial state, the first movable rail 121 can only float away from the second movable rail 122. This effectively maintains the relative position of the first and second movable rails 121, 122 during their reciprocating motion, ensuring synchronization. Furthermore, due to the elastic force, the first movable rail 121 automatically returns to its original position after floating relative to the second movable rail 122.

[0056] For further information, please refer to Figure 5 In this embodiment, the floating assembly 124 includes a connecting rod 1241 and a compression spring 1242. A mounting ring 1221 is provided on the second movable guide rail 122. The connecting rod 1241 is passed through the mounting ring 1221 and one end is connected to the first movable guide rail 121. The compression spring 1242 is sleeved on the connecting rod 1241 and clamped between the mounting ring 1221 and the end of the connecting rod 1241 away from the first movable guide rail 121.

[0057] A mounting ring 1221 is positioned on the backside of the second movable rail 122 to prevent interference with the oven door 300. A stopper (not shown) is formed at the end of the connecting rod 1241, distal from the first movable rail 121, to support the compression spring 1242. The compression of the compression spring 1242 generates a preload acting on the stopper and the mounting ring 1221, forcing the first and second movable rails 121, 122, toward each other. To maintain balance, multiple mounting rings 1221 can be positioned along the length of the second movable rail 122, with corresponding floating assemblies 124.

[0058] It should be noted that in other embodiments, the floating assembly 124 may also take other forms. For example, the first movable rail 121 and the second movable rail 122 may be connected by a U-shaped spring clip, with the first movable rail 121 and the second movable rail 122 respectively connected to the two sides of the U-shaped spring clip. The U-shaped spring clip can undergo elastic deformation, either inward or outward, thereby causing the first movable rail 121 to float relative to the second movable rail 122.

[0059] Please refer again Figure 4 In this embodiment, the support mechanism 120 includes a first limiting member 125 and a second limiting member 126. When the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to slide back and forth, the first limiting member 125 can limit the first movable guide rail 121 to a position relative to the fixed guide rail 110, and the second limiting member 126 can limit the second movable guide rail 122 to a position docking with the fixed guide rail 110.

[0060] The first limiting member 125 and the second limiting member 126 can respectively limit the position of the first movable guide rail 121 and the second movable guide rail 122 by mechanical limiting. Specifically, when the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to move away from the drying chamber, the first limiting member 125 can limit the maximum travel of the first movable guide rail 121, and dock with the fixed guide rail 110 when the first movable guide rail 121 reaches its maximum travel. When the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to move toward the drying chamber, the second limiting member 126 can limit the maximum travel of the second movable guide rail 122, and dock with the fixed guide rail 110 when the second movable guide rail 122 reaches its maximum travel. In this way, under the limiting action of the first limiting member 125 and the second limiting member 126, the position control of the first movable guide rail 121 and the second movable guide rail 122 is more precise, thereby ensuring better alignment with the fixed guide rail 110 during docking.

[0061] Furthermore, in this embodiment, the support mechanism 120 also includes a fixed plate 127, the first movable guide rail 121 and the second movable guide rail 122 can be slidably installed on the fixed plate 127, the first limiting member 125 is fixed to the fixed plate 127, and can abut against the side of the second movable guide rail 122 facing away from the first movable guide rail, and the second limiting member 126 is installed on the side of the second movable guide rail 122 facing away from the first movable guide rail, and can abut against the fixed guide rail 110.

[0062] Specifically, the first position-limiting member 125 can be a position-limiting screw fixed to the fixing plate 127. When the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to move away from the drying chamber, the first position-limiting member 125 can abut against the second movable guide rail 122 and limit the first movable guide rail 121 through the second movable guide rail 122, thereby limiting the maximum travel of the first movable guide rail 121.

[0063] The second stopper 126 can be a roughly L-shaped metal block that partially protrudes from the longitudinal end of the second movable guide rail 122. When the driver 123 drives the first and second movable guide rails 121, 122 toward the drying chamber, the second stopper 126 abuts against the fixed rail 110, thereby limiting the maximum travel of the second movable guide rail 122. This means that while the second stopper 126 limits the second movable guide rail 122, it does not affect the continued movement of the first movable guide rail 121 toward the drying chamber, thereby ensuring that the first movable guide rail 121 can float smoothly relative to the second movable guide rail 122.

[0064] Specifically, in this embodiment, two parallel slide rails 1271 are provided on the surface of the fixed plate 127, the two ends of the first movable guide rail 121 and the second movable guide rail 122 are slidably provided on the two slide rails 1271 respectively, and the driving member 123 is provided between the two slide rails 1271.

[0065] Both slide rails 1271 extend generally along the width of the fixed guide rail 110, i.e., the aforementioned front-to-back direction. The first and second movable guide rails 121, 122 are supported at both ends by the two slide rails 1271, respectively, ensuring greater stability during reciprocating sliding. Furthermore, positioning the driver 123 between the two slide rails 1271 ensures a more balanced driving force from the driver 123 on the first and second movable guide rails 121, 122.

[0066] Furthermore, in this embodiment, the driving end of the driving member 123 is connected to the first movable guide rail 121. That is, the driving member 123 directly acts on the first movable guide rail 121 and drives the second movable guide rail 122 to move synchronously through the first movable guide rail 121.

[0067] In this way, when the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to move back to the drying chamber until the first movable guide rail 121 docks with the fixed guide rail 110, the force applied by the driving member 123 to the first movable guide rail 121 can hold the first movable guide rail 121 and the second movable guide rail 122 against the first limiting member 125, thereby reliably limiting the first movable guide rail 121 so that the first movable guide rail 121 cannot float relative to the second movable guide rail 122, thereby ensuring a high degree of alignment between the first movable guide rail 121 and the fixed guide rail 110.

[0068] In addition, in this embodiment, the support mechanism 120 also includes a first sensor 128a, a second sensor 128b and a sensing plate 129. The sensing plate 129 is linked to the first movable guide rail 121 and the second movable guide rail 122, and the sensing plate 129 can trigger the first sensor 128a when the first movable guide rail 121 is docked with the fixed guide rail 110, and can trigger the second sensor 128b when the second movable guide rail 122 is docked with the fixed guide rail 110.

[0069] The first and second sensors 128a, 128b can employ the same structure, such as a grating sensor. The first and second sensors 128a, 128b are spaced apart along the width of the fixed rail 110 and can be fixedly mounted on the fixed plate 127. The sensing plate 129 can be mounted on either the first or second movable rail 121, 122, and can reciprocate along the width of the first or second movable rail 121, 122. To avoid false alarms, the sensing plate 129 is designed to be relatively wide to ensure smooth triggering of the first and second sensors 128a, 128b.

[0070] Specifically, when the first movable rail 121 moves to dock with the fixed rail 110, the oven door 300 it supports moves away from the drying chamber opening, placing the drying chamber in an open state. At this point, the induction plate 129 triggers the first sensor 128a. When the second movable rail 122 moves to dock with the fixed rail 110, the oven door 300 supported by the first movable rail 121 covers the drying chamber opening, placing the drying chamber in a closed state. At this point, the induction plate 129 triggers the second sensor 128b. Thus, the open and closed states of the oven door 300 can be detected based on the triggering of the first and second sensors 128a, 128b.

[0071] In the aforementioned side-opening door system 100 and battery drying oven 10, when the oven door 300 is closed in the drying chamber, it is supported by the first movable rail 121 of the corresponding support mechanism 120, while the second movable rail 122 of the corresponding support mechanism 120 interfaces with the fixed rail 110. At this point, the gap in the fixed rail 110 is filled by the second movable rail 122, allowing the remaining oven door 300 to slide smoothly along the fixed rail 110 to close or open. Furthermore, because the first movable rail 121 can float relative to the second movable rail 122 in the width direction, the relative position between the second movable rail 122 and the fixed rail 110 remains unchanged even when the position of the first movable rail 121 and the oven door 300 it supports changes. This maintains a high degree of alignment between the second movable rail 122 and the fixed rail 110, preventing the oven door 300 from getting stuck when passing through the junction. As can be seen, the aforementioned side-opening door system 100 and battery drying oven 10 make side-opening more convenient.
