Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a material hoist and a battery production line. Background Technology

[0002] After the battery cells are paired, they need to be transported via battery cell transfer pallets. Currently, these pallets are transported in a loop along the logistics line. To improve space utilization, the logistics line pallets are divided into upper and lower layers. A loading elevator lifts the pallets from the lower layer to the upper layer to hold the battery cells, allowing for repeated use.

[0003] In the relevant technologies, the pallet of the elevator is at risk of falling off during use. Utility Model Content

[0004] In view of the above problems, this application provides a material hoist and a battery production line, which can solve the problem of the risk of the pallet falling off during the use of the hoist.

[0005] To solve the above-mentioned technical problems, in a first aspect, this application proposes a material hoist, comprising:

[0006] support;

[0007] A conveying component is disposed on the support and is used to drive the tray to move along a first direction, the first direction being the height direction of the support;

[0008] A driving component, which is connected to the conveying component, is used to drive the conveying component to move along the first direction;

[0009] A locking element is disposed on the bracket and is used to lock the drive assembly to limit the drive assembly from driving the transmission assembly to move.

[0010] In the technical solution of this application embodiment, when the conveying component needs to stop moving, the driving component is locked by a locking member. At this time, the driving component cannot drive the conveying component to continue moving, and the position of the tray on the conveying component will be fixed to prevent the tray from shaking and falling off the conveying component.

[0011] In some embodiments, the locking element includes a gear and a blocking element, and the drive assembly includes a drive element and a drive shaft;

[0012] The driving component is mounted on the bracket, and the driving component drives the transmission assembly to move via the transmission shaft;

[0013] The gear is mounted on the drive shaft, and the blocking member is mounted on the bracket. The blocking member cooperates with the gear to prevent the gear from rotating. In this way, by blocking the gear from rotating, the drive shaft is prevented from rotating, thereby stopping the transmission assembly.

[0014] In some embodiments, the blocking member includes a fixed plate, a mounting base, a rotating block, and a rack;

[0015] The fixed plate is disposed on the bracket, the mounting base is disposed on the fixed plate, one end of the rotating block is rotatably connected to the mounting base, and the rack is disposed on the side of the rotating block opposite to the fixed plate;

[0016] When the rack and the gear are separated, the driving member drives the transmission assembly to move via the transmission shaft;

[0017] When the rack and gear mesh, the drive component stops moving. In this way, the movement of the transmission component can be easily controlled through the cooperation of the rack and gear.

[0018] In some embodiments, the locking member further includes a plug rod, and the mounting base has a plug hole on the side facing the rotating block;

[0019] The rack is separated from the gear, and the insert is disposed on the mounting base;

[0020] With the rack and gear meshing, the insert rod is inserted into the socket, and the insert rod is positioned below the rotating block. This ensures that the rack and gear mesh by inserting the insert rod into the corresponding socket.

[0021] In some embodiments, the locking member further includes a detection member disposed on the mounting base for detecting the position of the insertion rod;

[0022] The detection element is electrically connected to the driving element. When the insertion rod is inserted into the insertion hole, the detection element controls the driving element to close. In this way, by detecting the position of the insertion rod through the detection element, the opening and closing of the driving element can be easily controlled.

[0023] In some embodiments, the rotating block is provided with a movable groove along the second direction, the rack is disposed in the movable groove, and the rack is movable along the second direction, wherein the second direction intersects the first direction. When the driving component stops, due to inertia, it will still drive the transmission shaft to rotate a certain angle. At this time, the gear on the transmission shaft will also rotate synchronously. When the gear meshes with the rack, under the action of the movable groove, the gear can also drive the rack to move a certain distance within the movable groove, preventing collision between the gear and rack when the rack cannot move, thus avoiding damage to the gear and rack.

[0024] In some embodiments, the rotating block is provided with a handle for driving the rotating block to rotate about a third direction, wherein the third direction intersects the plane formed by the first direction and the second direction. This allows the rotating block to be easily moved via the handle.

[0025] In some embodiments, the locking member further includes a connecting block disposed on the side of the rotating block opposite to the rack;

[0026] The connecting block passes through the movable slot along the first direction and connects to the rack, used to adjust the distance between the rack and the gear. In this way, by adjusting the distance between the rack and the gear through the connecting block, it is ensured that the rack and the gear can effectively mesh together.

[0027] In some embodiments, the locking member further includes a connector, and the rotating block is rotatably connected to the mounting base via the connector;

[0028] When the connector is not under stress, the rack is separated from the gear; when the connector is under compression, the rack meshes with the gear.

[0029] In some embodiments, the material hoist further includes a tensioning assembly, and the conveying assembly includes a first drive wheel disposed on the support. The tensioning assembly cooperates with the first drive wheel to adjust the position of the first drive wheel in the first direction. This facilitates adjustment of the position of the first drive wheel on the conveying assembly.

[0030] In some embodiments, the material hoist further includes a buffer element disposed on one side of the support along a second direction, wherein the second direction intersects the first direction. This prevents the pallet from colliding with other components on the support.

[0031] In some embodiments, the material hoist further includes a pallet holder, and the conveying assembly includes a belt, with the pallet holder disposed on the belt.

[0032] In some embodiments, the pallet holder includes a support plate, a first roller, and a second roller;

[0033] The support plate extends along a second direction and is disposed on the belt. The first roller and the second roller are both disposed on the side of the support plate opposite to the belt.

[0034] The second roller is located at one end of the support plate facing the tray into the bracket, and the diameter of the second roller is larger than the diameter of the first roller.

[0035] In this way, when the pallet enters the support plate, when the pallet moves in the reverse direction, because the diameter of the second roller is larger than that of the first roller, the pallet will hit the second roller when it moves in the reverse direction. At this time, the second roller can hinder the reverse movement of the pallet and prevent the pallet from falling off the support plate.

[0036] In some embodiments, the material elevator further includes a chute extending along the first direction, the chute being disposed on the support, and the support plate having third rolling wheels at both ends along the second direction;

[0037] The tray is located on the first roller, and the third roller is located within the groove.

[0038] Secondly, this application proposes a battery production line, including a material hoist as described in any one of the embodiments of this application.

[0039] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0062] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0063] After the battery cells are paired, they need to be transported via battery cell transfer pallets. Currently, these pallets are transported in a loop along the logistics line. To improve space utilization, the logistics line pallets are divided into upper and lower layers. A loading elevator lifts the pallets from the lower layer to the upper layer to hold the battery cells, allowing for repeated use.

[0064] If a power outage occurs during maintenance of the feeding elevator, the battery cell tray may fall off. To address this issue, related technologies employ manual removal of the tray or locking it with a pin at the point of descent. However, manual removal still carries the risk of the tray falling due to the confined space of the feeding elevator. As for the pin method, excessive tray inertia can cause the pin to break, and it also fails to provide adequate structural control for belt-driven trays.

[0065] Based on the above considerations, in order to solve the problem of pallet detachment risk during the use of the elevator, a material elevator is designed. The material elevator includes a support, a conveying component, a driving component, and a locking component. The conveying component is set on the support and is used to drive the pallet to move along a first direction, which is the height direction of the support. The driving component is connected to the conveying component and is used to drive the conveying component to move. The locking component is set on the support and is used to lock the driving component to limit the driving component from driving the conveying component to move.

[0066] In the technical solution of this application embodiment, when the conveying component needs to stop moving, the driving component is locked by a locking member. At this time, the driving component cannot drive the conveying component to continue moving, and the position of the tray on the conveying component will be fixed to prevent the tray from shaking and falling off the conveying component.

[0067] According to some embodiments of this application, Figure 1 This is a schematic diagram of the material hoist in this application. Figure 2 for Figure 1 A side view. (e.g.) Figure 1 and Figure 2 As shown, this application provides a material hoist, which includes a support 10, a conveying assembly 11, a drive assembly 12, and a locking member 13. The conveying assembly 11 is disposed on the support 10 and is used to drive the pallet to move along a first direction, which is the height direction of the support 10. The drive assembly 12 is connected to the conveying assembly 11 and is used to drive the conveying assembly 11 to move. The locking member 13 is disposed on the support 10 and is used to lock the drive assembly 12 to limit the drive assembly 12 from driving the conveying assembly 11 to move.

[0068] The first direction in this embodiment is as follows: Figure 1 The X-axis direction in the diagram.

[0069] In this embodiment, the support 10 has multiple square tubes connected to form a cuboid or cube frame. The specific structure can be determined according to the actual situation, and this embodiment does not limit it.

[0070] In this embodiment, the conveying component 11 can be a belt conveyor mechanism, as shown in the reference. Figure 1 As shown, a conveying component 11 is provided on the left and right sides of the support 10, and a tray 18 is placed between the two conveying components 11. When the two conveying components 11 move, the tray 18 can be driven to move from top to bottom along the X-axis.

[0071] The drive assembly 12 in this embodiment may include a motor, a speed reducer, etc. The drive assembly 12 can be fixed to the bracket 10 by bolts. At the same time, the drive assembly 12 is connected to the conveying assembly 11. In use, by starting the drive assembly 12, the drive assembly 12 can drive the conveying assembly 11 to move, thereby driving the tray 18 on the conveying assembly 11 to move.

[0072] In this embodiment, when the material hoist is running normally, the drive component 12 drives the conveying component 11 to move, and the conveying component 11 drives the corresponding tray 18 to move from top to bottom along the X-axis. At this time, the locking member 13 does not restrict the movement of the drive component 12. When it is necessary for the conveying component 11 to stop moving, the locking member 13 locks the drive component 12. At this time, the drive component 12 cannot drive the conveying component 11 to continue moving, and the position of the tray 18 on the conveying component 11 will be fixed, preventing the tray 18 from shaking and falling off the conveying component 11.

[0073] According to some embodiments of this application, such as Figure 3 and combined Figure 1 As shown, the locking member 13 includes a gear 132 and a blocking member, and the driving assembly 12 includes a driving member 121 and a transmission shaft 123. The driving member 121 is disposed on the bracket 10, and the driving member 121 drives the transmission assembly 11 to move through the transmission shaft 123. At the same time, the gear 132 is disposed on the transmission shaft 123, and the blocking member is disposed on the bracket 10. The blocking member cooperates with the gear 132 to prevent the gear 132 from rotating.

[0074] refer to Figure 1 As shown, the drive assembly 12 in this embodiment also includes a pulley 122 and two right-angle reducers 124. The drive component 121 can be a stepper motor, DC motor, servo motor, etc. The two right-angle reducers 124 are distributed on the left and right sides of the bracket 10, respectively, and the transmission shaft 123 is connected between the two right-angle reducers 124. Both the drive component 121 and the right-angle reducers 124 can be fixed to the bracket 10 with bolts. The output shaft on the drive component 121 is connected to the pulley 122 through a conveyor belt.

[0075] In this embodiment, the right-angle reducer 124 is connected to the transmission wheel on the conveyor assembly 11. In use, the drive unit 121 drives the conveyor belt to move, and the conveyor belt can drive the pulley 122 to rotate. At this time, under the action of the pulley 122, the transmission shaft 123 can be driven to rotate, which in turn drives the right-angle reducer 124 to rotate. Finally, the right-angle reducer 124 can drive the corresponding transmission wheel to rotate, thereby realizing the movement of the conveyor assembly 11.

[0076] When the material hoist is running normally, the blocking component separates from the gear 132, and the drive component 121 runs normally. When the conveying component 11 needs to stop moving, the drive component 121 stops running. At the same time, the blocking component cooperates with the gear 132 to prevent the gear 132 from continuing to rotate. Since the gear 132 is fixed on the transmission shaft 123, and the transmission shaft 123 is connected to the conveying component 11 through the right-angle reducer 124, the blocking component can effectively prevent the conveying component 11 from continuing to move.

[0077] It should be noted that the structure of the drive component described above is merely an example. Other alternative structures can also be used. For instance, the drive component may also include a lead screw mechanism to drive the rotating shaft. This application does not impose any special restrictions on the specific structure of the drive component, as long as the above structure achieves the purpose of this application.

[0078] According to some embodiments of this application, such as Figure 3 and combined Figure 4 As shown, the blocking component includes a fixed plate 131, a mounting base 133, a rotating block 135, and a rack 136. The fixed plate 131 is mounted on the bracket 10, the mounting base 133 is mounted on the fixed plate 131, one end of the rotating block 135 is rotatably connected to the mounting base 133, and the rack 136 is located on the side of the rotating block 135 away from the fixed plate 131. When the rack 136 separates from the gear 132, the driving component 121 drives the transmission assembly 11 to move through the transmission shaft 123. When the rack 136 meshes with the gear 132, the driving component 121 stops moving.

[0079] In this embodiment, the fixing plate 131 is fixed to the bottom surface of the bracket 10 by bolts, the mounting base 133 is fixed to the upper surface of the fixing plate 131 by bolts, one end of the rotating block 135 can be rotatably connected to the mounting base 133 by a pin, the other end of the rotating block 135 is a free end, and the rack 136 can be bolted or snapped onto the side of the rotating block 135 facing the gear 132.

[0080] refer to Figure 3 As shown, rack 136 is initially separated from gear 132, at which point gear 132 can rotate normally and drive component 121 operates normally; when drive component 121 stops running, refer to Figure 4 As shown, at this time, the rack 136 meshes with the gear 132, thereby blocking the gear 132 from rotating. Since the gear 132 is fixed on the transmission shaft 123, and the transmission shaft 123 is connected to the transmission assembly 11 through the right angle reducer 124, the transmission assembly 11 can be effectively prevented from continuing to move.

[0081] In this embodiment, the rack 136 and gear 132 work together to effectively prevent the transmission assembly 11 from continuing to move when the drive unit 121 stops running.

[0082] According to some embodiments of this application, such as Figure 4 and combined Figure 3 As shown, the locking member 13 also includes a plug rod 134, and the mounting base 133 is provided with a plug hole 1331 on the side facing the rotating block 135; when the rack 136 is separated from the gear 132, the plug rod 134 is provided on the mounting base 133; when the rack 136 is engaged with the gear 132, the plug rod 134 is inserted into the plug hole 1331, and the plug rod 134 is located below the rotating block 135.

[0083] In this embodiment, the insertion rod 134 is inserted into the mounting base 133, and the rack 136 is initially separated from the gear 132. At this time, the insertion rod 134 is positioned as follows: Figure 4 In the correct position, gear 132 can rotate normally, and drive component 121 operates normally; when drive component 121 stops running, at this time, insert rod 134 is moved from the position indicated by... Figure 4 Pull it out from the position in the middle, and then insert it into the corresponding socket 1331. Under the support of the plug rod 134, the rotating block 135 drives the rack 136 to mesh with the gear 132, thereby blocking the gear 132 from rotating.

[0084] According to some embodiments of this application, such as Figure 5 and combined Figure 6 As shown, the locking member 13 also includes a detection member 137, which is disposed on the mounting base 133 and is used to detect the position of the insertion rod 134. The detection member 137 is electrically connected to the driving member 121. When the insertion rod 134 is inserted into the insertion hole 1331, the detection member 137 controls the driving member 121 to close.

[0085] In this embodiment, the detection element 137 can be a proximity switch, a position sensor, etc. The specific one can be determined according to the actual situation, and this embodiment does not limit it.

[0086] In this embodiment, the detection element 137 is used to detect the position of the insertion rod 134. When the insertion rod 134 is in such a position... Figure 4 When the rod is in the middle position, the drive unit 121 works normally; when the insertion rod 134 moves from the middle position... Figure 4 When the insertion rod 134 is pulled out from its position and then inserted into the socket 1331, the detection component 137 detects that the insertion rod 134 is not in the correct position. Figure 4 The position of the probe 134 is detected by the detector 137, which controls the drive 121 to close. In this way, the opening and closing of the drive 121 can be easily controlled by detecting the position of the probe 134 by the detector 137.

[0087] According to some embodiments of this application, such as Figure 7 and combined Figure 8 , Figure 9 As shown, the rotating block 135 is provided with a movable groove 1352 along the second direction, and the rack 136 is provided in the movable groove 1352 and can move along the second direction, wherein the second direction intersects with the first direction.

[0088] The second direction in this embodiment is as follows: Figure 7 The Y-axis direction in the diagram, where the angle between the X-axis and Y-axis can be 80°, 85°, 90°, etc. For ease of explanation, the following explanation will use the example of the X-axis and Y-axis being perpendicular to each other.

[0089] refer to Figure 9As shown, in this embodiment, the rack 136 has an extension 1361 on the side facing the fixed plate 131. The extension 1361 is integrally formed with the rack 136 and the extension 1361 is a slider structure. The extension 1361 is located in the corresponding movable groove 1352 and can move along the Y-axis in the movable groove 1352. The part of the rack 136 that meshes with the gear 132 is located outside the movable groove 1352.

[0090] When in use, when the drive component 121 stops, under the action of inertia, the drive component 121 will still drive the transmission shaft 123 to rotate a certain angle. At this time, the gear 132 on the transmission shaft 123 will also rotate synchronously. When the gear 132 meshes with the rack 136, under the action of the movable groove 1352, the gear 132 can also drive the rack 136 to move a certain distance along the Y-axis in the movable groove 1352. This avoids the gear 132 from colliding with the rack 136 when it rotates when the rack 136 cannot move, thus preventing damage to the gear 132 and the rack 136.

[0091] According to some embodiments of this application, such as Figure 4 As shown, a handle 1351 is provided on the rotating block 135 for driving the rotating block 135 to rotate around a third direction, wherein the third direction intersects the plane formed by the first direction and the second direction.

[0092] In this embodiment, the third direction is as follows: Figure 4 The Z-axis direction is perpendicular to the plane formed by the X-axis and Y-axis.

[0093] In this embodiment, the handle 1351 can be inserted into the rotating block 135, or the handle 1351 and the rotating block 135 can be integrally formed.

[0094] When rack 136 is in its initial state, refer to Figure 3 As shown, at this time, one end of the rotating block 135 hangs down under the action of gravity, the rack 136 separates from the gear 132, and the gear 132 can rotate normally;

[0095] When the drive unit 121 stops running, the rotating block 135 needs to be lifted so that the rack 136 on the rotating block 135 meshes with the gear 132. At this time, the rotating block 135 can be easily rotated relative to the mounting base 133 by the handle 1351 so that the rack 136 meshes with the gear 132.

[0096] According to some embodiments of this application, such as Figure 7 and combined Figure 8 , Figure 9As shown, the locking member 13 also includes a connecting block 138, which is disposed on the side of the rotating block 135 away from the rack 136; at the same time, the connecting block 138 passes through the movable groove 1352 along the first direction and is connected to the rack 136 to adjust the distance between the rack 136 and the gear 132.

[0097] The first direction in this embodiment can be referred to the description above, and will not be repeated here.

[0098] refer to Figure 9 As shown, a bolt 1381 is provided on the connecting block 138. The bolt 1381 passes through the connecting block 138 and connects to the extension 1361 on the rack 136. By rotating the bolt 1381, the extension 1361 moves toward the connecting block 138. When the bolt 1381 extends into the extension 1361 to different distances, the distance between the extension 1361 and the connecting block 138 will be different. At this time, the distance between the rack 136 and the gear 132 can be adjusted synchronously to ensure that the rack 136 and the gear 132 can effectively mesh together.

[0099] According to some embodiments of this application, such as Figure 10 and combined Figure 11 As shown, the locking member 13 also includes a connector 139, and the rotating block 135 is rotatably connected to the mounting base 133 through the connector 139; when the connector 139 is not under force, the rack 136 is separated from the gear 132, and when the connector 139 is under force and compressed, the rack 136 and the gear 132 mesh.

[0100] In this embodiment, the connecting member 139 may include a pin, a torsion spring, etc. The rotating block 135 is connected to the mounting base 133 through the cooperation structure of the pin and the torsion spring.
