Side door opening system and battery drying furnace

Abstract

The invention 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.

Description

Technical Field

[0001] The invention relates to the technical field of battery production equipment, and in particular to a side-opening door system and a battery drying furnace. Background Art

[0002] Lithium batteries need to be baked before filling to remove moisture from the battery cells. In order to save space, the drying oven used for baking generally adopts a side-opening door. When opening the door, first drive the furnace door away from the opening, then slide the furnace door sideways to the outside of the opening range. When closing the door, first slide the furnace door sideways to align with the opening, and then press the furnace door toward the opening. Usually, the structure of the door opening mechanism for side-opening is relatively complex, and it is easy to get stuck, which makes the side-opening operation more inconvenient. Summary of the invention

[0003] Based on this, it is necessary to provide a side-opening door system and a battery drying oven that are convenient for side-opening the door in order to solve the above problems.

[0004] A side-opening door system, comprising:

[0005] A fixed guide rail, having at least two spaced-apart notches formed along an extending direction of the fixed guide rail; and

[0006] a supporting mechanism arranged corresponding to the notch, the supporting mechanism comprising a first movable guide rail, a second movable guide rail, a driving member and a floating assembly, the first movable guide rail and the second movable guide rail being arranged in parallel and connected through the floating assembly so that the first movable guide rail can float relative to the second movable guide rail in a width direction;

[0007] The driving member can drive the first movable guide rail and the second movable guide rail to slide back and forth in the corresponding notch along the width direction of the fixed guide rail, so that the first movable guide rail and the second movable guide rail are alternately docked with the fixed guide rail.

[0008] In one embodiment, the floating component can provide an elastic force, and the first movable guide rail and the second movable guide rail are pressed against each other under the action of the elastic force.

[0009] In one embodiment, the floating assembly includes a connecting rod and a compression spring. A mounting ring is provided on the second movable guide rail. The connecting rod is passed through the mounting ring and one end is connected to the first movable guide rail. The compression spring is sleeved on the connecting rod and clamped between the mounting ring and the end of the connecting rod away from the first movable guide rail.

[0010] In one embodiment, the supporting mechanism includes a first limiting member and a second limiting member. When the driving member drives the first movable guide rail and the second movable guide rail to slide back and forth, the first limiting member can limit the first movable guide rail to a position corresponding to the fixed guide rail, and the second limiting member can limit the second movable guide rail to a position docking with the fixed guide rail.

[0011] In one embodiment, the support mechanism also includes a fixed plate, the first movable guide rail and the second movable guide rail are slidably mounted on the fixed plate, the first limiting member is fixed to the fixed plate and can abut against the side of the second movable guide rail facing away from the first guide rail, and the second limiting member is installed on the side of the second movable guide rail facing away from the first guide rail and can abut against the fixed guide rail.

[0012] In one of the embodiments, two parallel slide rails are disposed on the surface of the fixed plate, two ends of the first movable guide rail and the second movable guide rail are slidably disposed on the two slide rails, respectively, and the driving member is disposed between the two slide rails.

[0013] In one embodiment, the driving end of the driving member is connected to the first movable guide rail.

[0014] In one embodiment, the support mechanism further includes a first sensor, a second sensor and a sensing plate, wherein the sensing plate is linked to the first movable guide rail and the second movable guide rail, and the sensing plate can trigger the first sensor when the first movable guide rail is docked with the fixed guide rail, and can trigger the second sensor when the second movable guide rail is docked with the fixed guide rail.

[0015] In one of the embodiments, it further comprises a side sliding drive mechanism, and the side sliding drive mechanism can drive the furnace door to slide along the fixed guide rail.

[0016] A battery drying furnace, comprising:

[0017] A side-opening door system as described in any one of the above preferred embodiments;

[0018] A furnace body having at least two drying chambers, wherein the fixed guide rail is arranged along an edge of the furnace body, and the first movable guide rail is located on a side of the second movable guide rail facing the drying chambers; and

[0019] At least two furnace doors are respectively used to close the openings of at least two drying bins. At least two furnace doors are installed on the side-opening door system and can move closer to or farther away from the corresponding drying bins under the drive of the supporting mechanism.

[0020] In the above-mentioned side-opening door system and battery drying furnace, when the furnace door is in the closed drying chamber, it is supported by the first movable rail of the corresponding support mechanism, and the second movable rail of the corresponding support mechanism is docked with the fixed rail. At this time, the gap of the fixed rail will be filled by the second movable rail, so the remaining furnace doors can slide smoothly along the fixed rail to close or open the door. Moreover, since the first movable rail can float in the width direction relative to the second movable rail, when the position of the first movable rail and the supported furnace door changes, the relative position between the second movable rail and the fixed rail can also remain unchanged, so that the second movable rail and the fixed rail maintain a high degree of alignment, avoiding the furnace door from getting stuck when passing through the joint. It can be seen that the above-mentioned side-opening door system and battery drying furnace make side-opening more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0037] The furnace door 300 is installed on the side-opening door system 100. The side-opening door system 100 can drive the furnace door 300 to move in a direction perpendicular to the opening plane of the drying chamber (i.e., the front-to-back direction), so that the furnace door 300 is away from or close to the opening of the drying chamber, and can drive the furnace door 300 to slide in a direction parallel to the opening plane of the drying chamber (i.e., the left-right direction), so as to perform side-opening and closing operations. The furnace door 300 is generally provided with a supporting roller 310 for cooperating with the side-opening door system 100, so as to facilitate the sliding of the furnace door 300.

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

[0039] The fixed guide rail 110 adopts a discontinuous structure, and at least two gaps (not shown) are formed along the extension direction of the fixed guide rail 110. The fixed guide rail 110 is arranged along the edge of the furnace body 200, specifically the bottom edge in this embodiment. The support mechanism 120 is arranged corresponding to the gap, and the number of gaps on the fixed guide rail 110 is determined by the number of the support mechanisms 120. For example, if there are four support mechanisms 120, four gaps are formed on the fixed guide 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, the front-to-back direction, so that the furnace door 300 is close to or away from the corresponding drying bin. When the furnace door 300 is close to abutting 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 is away 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 read 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 in parallel and connected by a floating assembly 124. The lengths of the first movable rail 121 and the second movable rail 122 are similar to the lengths of the corresponding notches, and their widths are also substantially the same as the width of the fixed rail 110. Moreover, the first movable rail 121 is located on the side of the second movable rail 122 facing the drying chamber, that is, the first movable rail 121 is located on the inner side of the support mechanism 120, and the second movable rail 122 is located on the outer side of the support mechanism 120.

[0043] The first movable guide rail 121 and the second movable guide rail 122 are of split design and are not fixedly connected. The floating assembly 124 enables the first movable guide rail 121 to float in the width direction relative to the second movable guide rail 122. The width direction is consistent with the width direction of the fixed guide rail 110, that is, the front-to-back direction mentioned above. In other words, when the position of the second movable guide rail 122 is fixed, the first movable guide rail 121 can also 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 notch 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 are alternately docked 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 the two ends of the notch, and the two form a continuous track, and the second movable guide rail 121 exits from the side of the notch facing away from the drying chamber (see Figure 7Similarly, 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] In the process of closing the furnace 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 furnace door 300 is slid along the fixed guide rail 110 to the first movable guide rail 121, so that the furnace door 300 is in the closed position; the driving member 123 then drives the first movable guide rail 121 and the supported furnace door 300 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 furnace 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] It can be seen that when the oven door 300 closes the drying chamber, it is supported by the first movable guide rail 121 of the corresponding support mechanism 120, and 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 of the fixed guide rail 110 will be 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 door opening operation.

[0048] In 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 7 As 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 generally arranged at the bottom of the furnace body 200, that is, the fixed guide rail 110 is generally arranged along the bottom edge of the furnace body 200, so the side-opening door system 100 can support the furnace door 300 from bottom to top. In addition, another side-opening door system 100 can be arranged at the top edge of the furnace body 200. In this way, the two side-opening door systems 100 can support the furnace door 300 along the upper and lower ends of the furnace door 300, thereby improving the reliability of the support for the furnace door 300 and making the door opening and closing operations for the furnace door 300 smoother.

[0050] Please refer again Figure 3 In this embodiment, the side-opening door system 100 further includes a side-sliding driving mechanism 130, which can drive the furnace door 300 to slide along the fixed guide rail 110. The side-sliding driving mechanism 130 can drive the furnace door 300 to slide sideways by means of a servo motor driving a synchronous belt, a servo motor directly connected to a module, or a cylinder drive, thereby automatically driving the furnace 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 driving mechanism 130 may also be omitted, so that the 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 in a normal pressure state and a negative pressure state. In a negative pressure state, due to the large pressure difference between the inside and outside of the furnace door 300, the furnace door 300 presses the sealing ring to a greater extent than in a normal pressure state. Therefore, the position of the furnace door 300 will be closer to the opening edge of the drying chamber than in a normal pressure state. In other words, under different working conditions, the positions of the first movable guide rail 121 and the furnace door 300 supported by it may be different. Since the first movable guide rail 121 can float in the width direction relative to the second movable guide rail 122, 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 supporting 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 abut against each other under the action of the elastic force.

[0055] Since the first movable guide rail 121 and the second movable guide rail 122 are close to each other, the first movable guide rail 121 in the initial state can only float in the direction away from the second movable guide rail 122. In this way, in the process of driving the first movable guide rail 121 and the second movable guide rail 122 to move back and forth, the relative position of the two can be better maintained to a certain extent, ensuring that the two can keep in sync. Moreover, under the action of the elastic force, the first movable guide rail 121 can automatically reset after floating relative to the second movable guide rail 122.

[0056] For further information, please refer again 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] The mounting ring 1221 is arranged on the back side of the second movable guide rail 122 to avoid interference with the furnace door 300. A stopper (not shown) is formed at the end of the connecting rod 1241 away from the first movable guide rail 121, which is used to resist the compression spring 1242. The compression spring 1242 is compressed to generate a pre-tightening force acting on the stopper and the mounting ring 1221, so that the first movable guide rail 121 and the second movable guide rail 122 have a tendency to approach each other. In order to maintain balance, multiple mounting rings 1221 can be arranged along the length direction of the second movable guide rail 122, and multiple floating components 124 are arranged accordingly.

[0058] It should be noted that in other embodiments, the floating assembly 124 may also be in other forms. For example, the first movable rail 121 and the second movable rail 122 may be connected via a U-shaped spring sheet, and the first movable rail 121 and the second movable rail 122 are respectively connected to the two sides of the U-shaped spring sheet. The U-shaped spring sheet can undergo elastic deformation such as inward or outward expansion, thereby making the first movable rail 121 float relative to the second movable rail 122.

[0059] Please refer again Figure 4In this embodiment, the support mechanism 120 includes a first limit member 125 and a second limit 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 limit member 125 can limit the first movable guide rail 121 to a position corresponding to the fixed guide rail 110, and the second limit member 126 can limit the second movable guide rail 122 to a position docking with the fixed guide rail 110.

[0060] The first limiter 125 and the second limiter 126 can respectively limit 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 bin, the first limiter 125 can limit the maximum stroke of the first movable guide rail 121, and dock with the fixed guide rail 110 when the first movable guide rail 121 reaches the maximum stroke; when the driving member 123 drives the first movable guide rail 121 and the second movable guide rail 122 to move toward the drying bin, the second limiter 126 can limit the maximum stroke of the second movable guide rail 122, and dock with the fixed guide rail 110 when the second movable guide rail 122 reaches the maximum stroke. In this way, under the limiting action of the first limiter 125 and the second limiter 126, the position control of the first movable guide rail 121 and the second movable guide rail 122 is more accurate, 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 are slidably installed on the fixed plate 127, the first limit 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 guide rail, and the second limit member 126 is installed on the side of the second movable guide rail 122 facing away from the first guide rail, and can abut against the fixed guide rail 110.

[0062] Specifically, the first position-limiting member 125 may 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 the first movable guide rail 121 is limited by the second movable guide rail 122, thereby limiting the maximum travel of the first movable guide rail 121.

[0063] The second stopper 126 may be a substantially L-shaped metal block, and partly protrudes from the end of the length direction of the second movable guide rail 122. 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 stopper 126 can abut against the fixed guide rail 110 to limit the maximum travel of the second movable guide rail 122. It can be seen that when the second stopper 126 limits the second movable guide rail 122, it does not affect the first movable guide rail 121 from continuing to move 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 disposed on the surface of the fixed plate 127 , both ends of the first movable guide rail 121 and the second movable guide rail 122 are slidably disposed on the two slide rails 1271 , respectively, and the driving member 123 is disposed between the two slide rails 1271 .

[0065] The two slide rails 1271 extend roughly along the width direction of the fixed guide rail 110, that is, the front-to-back direction. The two ends of the first movable guide rail 121 and the second movable guide rail 122 are supported by the two slide rails 1271, respectively, so that higher stability can be maintained during the reciprocating sliding process. Moreover, the drive member 123 is arranged between the two slide rails 1271, so that the driving force of the drive member 123 on the first movable guide rail 121 and the second movable guide rail 122 can be more balanced.

[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 is docked 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 sensor 128a and the second sensor 128b can adopt the same structure, such as a grating sensor. The first sensor 128a and the second sensor 128b are arranged at intervals along the width direction of the fixed guide rail 110, and can be fixedly installed on the fixed plate 127. The induction sheet 129 can be installed on any one of the first movable guide rail 121 and the second movable guide rail 122, and can move back and forth along the width direction with the first movable guide rail 121 and the second movable guide rail 122. In order to avoid false alarms, the induction sheet 129 is set wider to ensure that the first sensor 128a and the second sensor 128b can be triggered smoothly.

[0070] Specifically, when the first movable rail 121 moves to dock with the fixed rail 110, the furnace door 300 supported by it is away from the opening of the drying chamber, and the drying chamber is in an open state. At this time, the induction sheet 129 triggers the first sensor 128a. When the second movable rail 122 moves to dock with the fixed rail 110, the furnace door 300 supported by the first movable rail 121 covers the opening of the drying chamber, and the drying chamber is in a closed state. At this time, the induction sheet 129 triggers the second sensor 128b. It can be seen that according to the situation in which the first sensor 128a and the second sensor 128b are triggered, the open and close state of the furnace door 300 can be detected.

[0071] In the above-mentioned 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, and the second movable rail 122 of the corresponding support mechanism 120 is docked with the fixed rail 110. At this time, the gap of the fixed rail 110 will be filled by the second movable rail 122, so the remaining oven doors 300 can slide smoothly along the fixed rail 110 to close or open the door. Moreover, since the first movable rail 121 can float in the width direction relative to the second movable rail 122, when the position of the first movable rail 121 and the oven door 300 supported by it changes, the relative position between the second movable rail 122 and the fixed rail 110 can also remain unchanged, so that the second movable rail 122 and the fixed rail 110 maintain a high degree of alignment, and avoid the oven door 300 from getting stuck when passing through the joint. It can be seen that the above-mentioned side-opening door system 100 and battery drying oven 10 make the side-opening door more convenient.
