Description

Technical Field

[0001] The invention relates to the technical field of battery drying, in particular to a drying device. Background Art

[0002] In the preparation process of lithium batteries, moisture control is particularly important. Too much moisture content can easily lead to increased internal resistance, low capacity, and poor cycle life, which directly affects the performance of the battery. Therefore, a drying process is generally required to remove moisture before the battery is filled with liquid.

[0003] At present, vacuum drying furnaces are generally used to dry battery cells, and the doors of vacuum drying furnaces often adopt a rocker-type switch door structure. However, the rocker-type switch door structure takes up a large space during the opening and closing process, resulting in low space utilization and is not conducive to layout in a narrow environment. Summary of the invention

[0004] Based on this, it is necessary to provide a drying device that improves the above defects in order to solve the problem that the furnace door in the prior art occupies a large space during opening and closing, resulting in low space utilization and being unfavorable for arrangement in a narrow environment.

[0009] The track assembly is also constructed to drive any of the furnace doors to move along the second direction, and each of the furnace doors passes through the alignment position and the mating position where it mates with the furnace body 10 and closes the corresponding opening during the movement along the second direction.

[0010] In one embodiment, the track assembly includes a mounting seat mounted on the furnace body, and at least two movable seats movably connected to the mounting seat along the second direction; the mounting seat is provided with a fixed track extending longitudinally along the first direction, and each of the movable seats is provided with a first track extending longitudinally along the first direction;

[0011] Each of the furnace doors is movably connected to the first track on the corresponding movable seat. When the movable seat drives the corresponding furnace door to move to the alignment position, the first track docks with the fixed track.

[0012] In one of the embodiments, each of the movable seats is further provided with a second track, which is parallel to the first track and is arranged at intervals with the first track along the second direction; when the movable seat drives the corresponding furnace door to move to the matching position, the second track on the movable seat docks with the fixed track.

[0013] In one of the embodiments, the track assembly further comprises a first driving mechanism, which is disposed on the mounting seat and can be drivingly connected to the furnace door at the aligned position and the open position.

[0014] In one embodiment, the first driving mechanism includes a driving plate and a first driving structure, the driving plate is movably connected to the mounting seat along the first direction, and the first driving structure is disposed on the mounting seat and is drivingly connected to the driving plate;

[0015] The driving plate has a connecting portion, and each of the oven doors has a matching portion. When the oven doors move along the second direction to the alignment position, the connecting portion can be plugged into and matched with the matching portion of the oven doors, so that the oven doors can move along the first direction with the driving plate.

[0016] In one embodiment, the first driving structure further includes a driving wheel, a driven wheel, a transmission belt and a first driving member;

[0017] The driving wheel and the driven wheel are arranged on the mounting seat at intervals along the first direction, and the transmission belt is sleeved between the driving wheel and the driven wheel to move forward sequentially along the first direction under the drive of the driving wheel. The transmission belt is connected to the driving plate, and the first driving member is arranged on the mounting seat and is transmission-connected to the driving wheel.

[0018] In one embodiment, the track assembly further includes at least two second driving mechanisms corresponding to at least two of the moving seats, each of the second driving mechanisms is disposed on the mounting seat and is transmission-connected to the corresponding moving seat.

[0019] In one of the embodiments, the furnace door device further comprises a traveling mechanism installed on the furnace door, and the traveling mechanism is movably connected to the first track and the fixed track.

[0020] In one embodiment, the fixed rail and the first rail have two opposite first rail surfaces in the second direction, each of the first rail surfaces extends longitudinally along the first direction, the walking mechanism includes a mounting plate and a first walking wheel group mounted on the mounting plate, and the first walking wheel group includes two first walking wheels arranged at intervals along the second direction;

[0023] When the traveling mechanism is movably connected to the fixed track, the plurality of second traveling wheels roll with the second rail surface of the fixed track; when the traveling mechanism is movably connected to the first track, the plurality of second traveling wheels roll with the moving seat.

[0024] In one embodiment, a baffle is provided on the movable seat at the end of the furnace body in the first direction, and a stopper is provided on the mounting seat;

[0025] The baffle is used to cooperate with the stopper to prevent the traveling mechanism from moving along the first track when the traveling mechanism drives the corresponding furnace door to leave the alignment position and move toward the matching position.

[0026] In the above drying equipment, when one of the openings needs to be opened, the track assembly drives the furnace door corresponding to the opening to be opened to move from the matching position to the alignment position along the second direction, and then moves from the alignment position to the open position along the first direction under the drive of the track assembly, thereby opening the opening to be opened, so as to facilitate the delivery or removal of the dried object; and at this time, the furnace door at least partially overlaps with the other furnace door in the second direction perpendicular to the first direction. In this way, on the one hand, the furnace door moves from the alignment position to the open position in a manner of translation along the first direction, and on the other hand, when in the open position, the furnace door partially overlaps with the other furnace door in the second direction, so that the furnace door does not need to occupy a large space in the entire process from closing the opening to opening the opening, thereby improving space utilization and being more suitable for being arranged in a narrow environment.

[0037] Before describing the drying device of the present invention, the rocker switch door structure of the vacuum drying furnace in the prior art is briefly described:

[0038] The rocker-type switch door structure includes furnace doors corresponding to the openings of the furnace body, and a rocker assembly that drives the furnace doors to flip downward to open the corresponding openings. The rocker assembly generally needs to be installed on the left and right sides of the furnace body. Since the rocker assembly itself has a certain volume, and the rocker assembly often needs to be maintained and repaired and requires reserved operating space, it is necessary to occupy a large space on the left and right sides of the furnace body. Furthermore, when the furnace door located at the bottom flips downward to open the corresponding opening, the furnace door needs to occupy the bottom space of the furnace body, which increases the height of the furnace body. In summary, the vacuum drying furnace in the current technology adopts a rocker-type switch door structure, which needs to occupy a large space at the bottom and left and right sides of the furnace body, and the space utilization rate is low, and it is not suitable for arrangement in a narrow environment. Therefore, it is necessary to provide a method to reduce the space required to be occupied and improve the space utilization rate, so that it can be more suitable for arrangement in a narrow environment.

[0039] See also Figure 1 , Figure 2 and Figure 3 As shown, a drying device provided in one embodiment of the present invention includes a furnace body 10 and a furnace door device 20. The furnace body 10 has at least two openings arranged at intervals along a first direction, and objects to be dried (such as battery cells) can enter the furnace body 10 from the openings for drying. The furnace door device 20 includes a track assembly 21 and at least two furnace doors 22 corresponding to the at least two openings, so that the corresponding openings can be closed or opened by using the furnace doors 22. The track assembly 21 is arranged on the furnace body 10 and matched with each furnace door 22.

[0040] The track assembly 21 is configured to drive any furnace door 22 to move along a first direction. During the movement of each furnace door 22 along the first direction, it passes through an aligned position aligned with the corresponding opening in a second direction, and an open position partially overlapping with another furnace door 22 in the second direction. The second direction is perpendicular to the first direction.

[0041] The track assembly 21 is also configured to drive any furnace door 22 to move along the second direction. During the movement of each furnace door 22 along the second direction, the furnace door 22 passes through an alignment position and a matching position where the furnace door 22 matches with the furnace body 10 and closes the corresponding opening.

[0042] In the above drying equipment, when one of the openings needs to be opened, the track assembly 21 drives the furnace door 22 corresponding to the opening to be opened to move from the matching position to the alignment position along the second direction, and then moves from the alignment position to the open position along the first direction under the drive of the track assembly 21, thereby opening the opening to be opened, so as to facilitate the delivery or removal of the dried object; and at this time, the furnace door 22 at least partially overlaps with another furnace door 22 in the second direction perpendicular to the first direction. In this way, on the one hand, the furnace door 22 moves from the alignment position to the open position in a translational manner along the first direction, and on the other hand, when in the open position, the furnace door 22 partially overlaps with another furnace door 22 in the second direction, so that the furnace door 22 does not need to occupy a large space in the entire process from closing the opening to opening the opening, thereby improving space utilization and being more suitable for arrangement in a narrow environment.

[0043] It should be noted that, when the opening needs to be opened, the corresponding furnace door 22 is first driven to move from the matching position along the second direction to the alignment position, that is, the alignment position is located on the side of the matching position away from the furnace body 10. On the one hand, the furnace door 22 is separated from the furnace body 10, and on the other hand, the furnace door 22 can overlap with other furnace doors 22 in the second direction during the movement along the first direction without interfering with other furnace doors 22.

[0044] Furthermore, the track assembly 21 is arranged on a side of the furnace body 10 having an opening, that is, on the front side of the furnace body 10 , thereby not occupying the space on the left and right sides of the furnace body 10 , further improving space utilization.

[0045] It should be noted that the drying equipment may be a vacuum drying equipment, and of course may be other types of drying equipment, which is not limited here.

[0046] It is understandable that, since each furnace door 22 corresponds to a different opening, each furnace door 22 has a corresponding open position, an aligned position, and a mating position during movement along the first direction and the second direction. In other words, the open position, the aligned position, and the mating position corresponding to each furnace door 22 are different, and the open position and the aligned position corresponding to each furnace door 22 are all located on a straight line parallel to the first direction.

[0047] In some embodiments, the track assembly 21 includes a mounting seat 211 and at least two moving seats 212. The mounting seat 211 is mounted on the furnace body 10, and a fixed track 2112 extending longitudinally along the first direction is disposed on the mounting seat 211. Each moving seat 212 is provided with a first track 2123 extending longitudinally along the first direction.

[0048] Each furnace door 22 is movably connected to the first track 2123 on the corresponding moving seat 212. When the moving seat 212 drives the corresponding furnace door 22 to move to the alignment position along the second direction, the first track 2123 docks with the fixed track 2112, so that the furnace door 22 can move along the first track 2123 to the fixed track 2112, and move to the open position along the fixed track 2112. In this way, the furnace door 22 can move along the second direction with the moving seat 212 (i.e., move between the matching position and the alignment position), and when the moving seat 212 drives the furnace door 22 to move to the alignment position, the first track 2123 on the moving seat 212 docks with the fixed track 2112, so that the furnace door 22 can move along the first track 2123 to the fixed track 2112, and move along the fixed track 2112 (i.e., move between the alignment position and the open position), thereby realizing that the furnace door 22 opens or closes the corresponding opening.

[0049] Specifically in the embodiment, each movable seat 212 is further provided with a second track 2124, which is parallel to the first track 2123 and spaced apart from the first track 2123 along the second direction. When the movable seat 212 drives the corresponding furnace door 22 to move to the mating position, the second track 2124 on the movable seat 212 docks with the fixed track 2112, so that other furnace doors can pass through during the process of opening.

[0050] The following is an explanation of the process of opening and closing the furnace door 22 by taking the furnace body 10 having two openings as an example: for the convenience of description, the two openings are named as the first opening and the second opening, the furnace door 22 corresponding to the first opening is named as the first furnace door, and the furnace door 22 corresponding to the second opening is named as the second furnace door; the matching position, alignment position and open position corresponding to the first furnace door are named as the first matching position, the first alignment position and the first open position respectively; the matching position, alignment position and open position corresponding to the second furnace door are named as the second matching position, the second alignment position and the second open position respectively.

[0051] Initially, the first furnace door is in the first mating position, so that the first furnace door is mated with the furnace body 10, thereby closing the first opening. At this time, the first furnace door is movably connected to the first track 2123 on the corresponding movable seat 212, and the second track 2124 on the movable seat 212 corresponding to the first furnace door is docked with the fixed track 2112. The second furnace door is also in the second mating position, so that the second furnace door is mated with the furnace body 10, thereby closing the second opening. At this time, the second furnace door is movably connected to the first track 2123 on the corresponding movable seat 212, and the second track 2124 on the movable seat 212 corresponding to the second furnace door is docked with the fixed track 2112.

[0052] When the first opening needs to be opened, first, the first furnace door moves to the first alignment position along the second direction driven by the corresponding movable seat 212, so that the first track 2123 on the movable seat 212 corresponding to the first furnace door docks with the fixed track 2112. Then, the first furnace door moves to the fixed track 2112 along the first track 2123, and moves toward the second furnace door along the fixed track 2112 until it reaches the first open position. At this time, the first furnace door and the second furnace door partially or completely overlap in the second direction. It should be noted that, since the second track 2124 on the movable seat 212 corresponding to the second furnace door docks with the fixed track 2112, the first furnace door can pass through the second track 2124 during the process of moving along the fixed track 2112 to the first open position, so that the first furnace door can smoothly move to the first open position.

[0053] When the first opening needs to be closed, the first furnace door returns to the first alignment position along the fixed track 2112, so that the first furnace door is movably connected to the first track 2123 on the corresponding movable seat 212. Then the movable seat 212 corresponding to the first furnace door moves along the second direction to the first mating position, so that the first furnace door is mated with the furnace body 10 to close the first opening.

[0054] When the second opening needs to be opened, first, the second furnace door moves to the second alignment position along the second direction driven by the corresponding movable seat 212, so that the first track 2123 on the movable seat 212 corresponding to the second furnace door docks with the fixed track 2112. Then, the second furnace door moves to the fixed track 2112 along the first track 2123, and moves toward the first furnace door along the fixed track 2112 until it reaches the second open position. At this time, the second furnace door and the first furnace door partially or completely overlap in the second direction. It should be noted that, since the second track 2124 on the movable seat 212 corresponding to the first furnace door docks with the fixed track 2112, the second furnace door can pass through the second track 2124 during the process of moving along the fixed track 2112 to the second open position, so that the second furnace door can smoothly move to the second open position.

[0055] When the second opening needs to be closed, the second furnace door returns to the second alignment position along the fixed track 2112, so that the second furnace door is movably connected to the first track 2123 on the corresponding movable seat 212. Then the movable seat 212 corresponding to the second furnace door moves along the second direction to the second matching position, so that the second furnace door is matched with the furnace body 10 to close the second opening.

[0056] In an embodiment of the present invention, the track assembly 21 also includes a first driving mechanism 213, which is disposed on the mounting seat 211 and can be transmission-connected to the furnace door 22 located at the alignment position and the open position to drive the furnace door 22 to move between the alignment position and the open position.

[0057] Specifically in the embodiment, the first driving mechanism 213 includes a driving plate 2131 and a first driving structure. The driving plate 2131 is movably connected to the mounting base 211 along a first direction. The first driving structure is disposed on the mounting base 211 and is transmission-connected to the driving plate 2131 to drive the mounting plate 231 to move along the first direction.

[0058] The driving plate 2131 has a connection portion a, and each furnace door 22 has a matching portion. When the furnace door 22 moves to the alignment position along the second direction, the connection portion a of the driving plate 2131 can be plugged and matched with the matching portion of the furnace door 22, so that the furnace door 22 can move along the first direction with the driving plate 2131. Optionally, the matching portion can be a plug hole, and the connection portion a can be plugged into the plug hole, so that the driving plate 2131 can drive the furnace door 22 to move along the first direction.

[0059] Specifically in the embodiment, a first slider is provided on the driving plate 2131, and a first slide rail 2113 extending longitudinally along a first direction is provided on the mounting seat 211. The first slider is slidably engaged with the first slide rail 2113, so that the driving plate 2131 can move along the first direction.

[0060] Specifically in the embodiment, the first driving structure further includes a driving wheel 2132, a driven wheel 2133, a transmission belt 2134 and a first driving member 2135. The driving wheel 2132 and the driven wheel 2133 are arranged on the mounting seat 211 at intervals along the first direction, and the transmission belt 2134 is sleeved between the driving wheel 2132 and the driven wheel 2133 to sequentially move forward along the first direction under the drive of the driving wheel 2132. The transmission belt 2134 is connected to the driving plate 2131 to drive the driving plate 2131 to move along the first direction. The first driving member 2135 is disposed on the mounting seat 211 and is transmission-connected to the driving wheel 2132 to drive the driving wheel 2132 to rotate. In this way, the first driving member 2135 drives the driving wheel 2132 to rotate, thereby driving the transmission belt 2134 to move between the driving wheel 2132 and the driven wheel 2133 along the first direction, and then drives the driving plate 2131 to move along the first direction. Optionally, the first driving member 2135 may be a motor. The output shaft of the first driving member 2135 and the axle of the driving wheel 2132 may be connected via a synchronous belt transmission, so that the first driving member 2135 can drive the driving wheel 2132 to rotate.

[0061] In the embodiment of the present invention, the track assembly 21 further includes at least two second driving mechanisms 214 corresponding to at least two moving seats 212. Each second driving mechanism 214 is disposed on the mounting seat 211 and is transmission-connected to the corresponding moving seat 212 to drive the moving seat 212 to move along the second direction.

[0062] Specifically in the embodiment, the second driving mechanism 214 includes a second driving member 2141, and the second driving member 2141 has a mounting end and a telescopic end that is telescopic relative to the mounting end. The mounting end is connected to the mounting seat 211, and the telescopic end is connected to the moving seat 212, so that when the telescopic end is telescopic relative to the mounting end, the moving seat 212 is driven to move along the second direction. Optionally, the second driving member 2141 can be a cylinder.

[0063] Specifically in the embodiment, a second slider 2121 is provided on the movable seat 212, and a second slide rail 2111 extending longitudinally along the second direction is provided on the mounting seat 211. The second slider 2121 is slidably matched with the second slide rail 2111, so that the movement of the movable seat 212 along the second direction is more stable and reliable.

[0064] See also Figures 1 to 4 As shown, in an embodiment of the present invention, the furnace door device 20 also includes a walking mechanism 23 installed on the furnace door 22, and the walking mechanism 23 can be movably connected to the first track 2123 and the fixed track 2112, so that the furnace door 22 can move along the first track 2123 and the fixed track 2112.

[0065] Specifically in the embodiment, the fixed rail 2112 and the first rail 2123 have two first rail surfaces opposite to each other in the second direction, and each first rail surface extends longitudinally along the first direction. The walking mechanism 23 includes a mounting plate 231 and a first walking wheel set 232 mounted on the mounting plate 231, and the first walking wheel set 232 includes two first walking wheels 2321 arranged at intervals along the second direction.

[0066] When the running mechanism 23 is movably connected to the fixed track 2112, the two first running wheels 2321 respectively roll with the two first rail surfaces of the fixed track 2112, thereby limiting the running mechanism 23 in the second direction, so that the running mechanism 23 can move along the fixed track 2112. When the running mechanism 23 is movably connected to the first track 2123, the two first running wheels 2321 respectively roll with the two first rail surfaces of the first track 2123, thereby limiting the running mechanism 23 in the second direction, so that the running mechanism 23 can move along the first track 2123.

[0067] Furthermore, the first running wheel set 232 may include multiple sets (ie, two sets or more), and the multiple sets of first running wheel sets 232 are arranged at intervals along the first direction.

[0068] Furthermore, a avoidance groove b extending longitudinally along the first direction is provided on the mounting plate 231, and the two first running wheels 2321 in each group of first running wheel groups 232 are respectively located on opposite sides of the avoidance groove b, so that when the walking mechanism 23 is movably connected to the track (i.e., the fixed track 2112, the first track 2123 or the second track 2124), the avoidance groove b can play a role in avoiding the track, thereby avoiding interference when the walking mechanism 23 moves along the track.

[0069] Specifically in the embodiment, the fixed rail 2112 has a second rail surface perpendicular to the first rail surface, and the second rail surface extends longitudinally along the first direction. The walking mechanism 23 also includes a plurality of second walking wheels 233 mounted on the mounting plate 231 .

[0070] When the traveling mechanism 23 is movably connected to the fixed rail 2112, the plurality of second traveling wheels 233 roll with the second rail surface of the fixed rail 2112, thereby supporting the furnace door 22 and the traveling mechanism 23 in the third direction, so that the traveling mechanism 23 can move along the fixed rail 2112.

[0071] Furthermore, the fixed track 2112 includes a horizontal plate fixedly connected to the mounting seat 211 and a first vertical plate erected on a side of the horizontal plate away from the mounting seat 211, and the horizontal plate and the first vertical plate both extend longitudinally along the first direction. The surfaces of the first vertical plate on the opposite sides in the second direction are the two first rail surfaces of the fixed track 2112, and the surface of the horizontal plate on one side facing the vertical plate is the second rail surface of the fixed track 2112.

[0072] Specifically in the embodiment, when the walking mechanism 23 is movably connected to the first track 2123, the multiple second walking wheels 233 roll with the moving seat 212 to support the furnace door 22 and the walking mechanism 23 in the third direction, so that the walking mechanism 23 can move along the first track 2123.

[0073] Furthermore, the plurality of second traveling wheels 233 are respectively located on opposite sides of the avoidance groove b, so that the movement of the furnace door 22 along the track with the traveling mechanism 23 is more stable and reliable.

[0074] Specifically in the embodiment, the travel mechanism 23 may also be movably connected to the second track 2124, so that the travel mechanism 23 may pass through the second track 2124 when moving along the fixed track 2112. It should be noted that the second track 2124 and the first track 2123 use the same track.

[0075] Furthermore, the first track 2123 and the second track 2124 both include a second longitudinal plate erected on the movable seat 212, and the second longitudinal plate extends longitudinally along the first direction. The surfaces of the second longitudinal plate on opposite sides in the second direction are two first rail surfaces of the first track 2123 or the second track 2124.

[0076] Specifically in the embodiment, a baffle is provided on the moving seat 212 at the end of the furnace body 10 in the first direction, and the baffle can be used to prevent the walking mechanism 23 from sliding out along the first track 2123 to the outside of the furnace body 10 and derailing. Further, a stopper is provided on the mounting seat 211, and the stopper is used to cooperate with the baffle to block the walking mechanism 23 from reciprocating along the first track 2123 when the walking mechanism 23 drives the corresponding furnace door 22 to leave the alignment position and move to the matching position along the second direction, which is conducive to improving the matching degree between the furnace door 22 and the furnace body 10 and improving the effect of sealing the opening. Of course, when the walking mechanism 23 drives the corresponding furnace door 22 to move to the alignment position, the stopper cannot prevent the walking mechanism 23 from moving from the first track 2123 to the fixed track 2112.

[0077] In the embodiment of the present invention, the furnace body 10 has a plurality of openings, and the plurality of openings are arranged in layers along the third direction. Each layer of openings includes at least two openings arranged at intervals along the first direction. Each layer of openings is correspondingly provided with a furnace door device 20 for closing or opening each opening in the corresponding layer.

[0078] Further, each furnace door device 20 includes two track assemblies 21, which are respectively located on both sides of the corresponding layer in the third direction, and are respectively matched with both sides of the furnace door 22 in the third direction, so that the opening and closing of the furnace door 22 corresponding to the opening is more stable and reliable. Specifically, both sides of the furnace door 22 in the third direction are respectively matched with the corresponding track assemblies 21 through the running mechanism 23. It can be understood that due to the effect of gravity, the second running wheel 233 of the running mechanism 23 located at the top of the furnace door 22 will not roll with the second rail surface or the moving seat 212, so the running mechanism 23 may not be provided with the second running wheel 233.

[0079] It should be noted that the furnace body 10 may also have only one layer of openings. In this case, only one furnace door device 20 is provided on the furnace body 10, and two track components 21 of the furnace door device 20 are respectively located on both sides of the layer of openings in the third direction.

[0080] It should also be noted that in Figure 1 and Figure 2 In the illustrated embodiment, the first direction is the left-right direction, the second direction is the direction perpendicular to the paper surface, and the third direction is the up-down direction.

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
