The operator can observe the internal operation through the transparent material part, which is convenient for determining the time of opening / closing the cover plate assembly.

[0026] According to some embodiments of the present application, the minimum distance between the first opening and the second opening is greater than or equal to 800 mm. The existence of a certain distance between the first cover plate assembly and the second cover plate assembly reduces the possibility of injury caused by the mechanical arm or the operator's arm mistakenly extending into the transfer box due to the closure of the cover plate.

[0059] Next, the structure of the battery transporting device 100 will be described in combination with FIG. 1 to FIG. 6.

[0060] Please refer to FIG. 1 to FIG. 5, FIG. 1 is a structural schematic diagram of the battery transporting device provided by some embodiments of the present application, FIG. 2 is a structural schematic diagram of the first cover plate assembly in a closed state provided by some embodiments of the present application, FIG. 3 is a structural schematic diagram of the first cover plate assembly in an open state provided by some embodiments of the present application, FIG. 4 is a structural schematic diagram of the second cover plate assembly in a closed state provided by some embodiments of the present application, and FIG. 5 is a structural schematic diagram of the second cover plate assembly in an open state provided by some embodiments of the present application.

[0061] In a first aspect, the embodiments of the present application provide a battery transfer device 100, comprising a transfer assembly 10, a first cover plate assembly 20, and a second cover plate assembly 30. The transfer assembly 10 comprises a transfer box 11 and a transfer piece 12 arranged in the transfer box 11. The transfer box 11 has a first opening 111 and a second opening 112 at opposite ends thereof. The transfer piece 12 is movable between the first opening 111 and the second opening 112. The first cover plate assembly 20 is arranged at the first opening 111. The first cover plate assembly 20 is in communication with a battery processing equipment. The first cover plate assembly 20 is switchable between an open state in which the first opening 111 is open and a closed state in which the first opening 111 is closed. The second cover plate assembly 30 is arranged at the second opening 112. The second cover plate assembly 30 is switchable between an open state in which the second opening 112 is open and a closed state in which the second opening 112 is closed. The second cover plate assembly 30 is configured to be switchable to the open state when the first cover plate assembly 20 is in the closed state.

[0062] The present application provides a battery transfer device 100 for moving a processed battery device or a semi-finished battery device, which can be moved between different equipment or taken out of a processing equipment.

[0063] Specifically, the battery transfer device 100 comprises a transfer assembly 10 for moving a battery device, and a first cover plate assembly 20 and a second cover plate assembly 30 for closing openings at opposite sides of the transfer assembly 10. The transfer assembly 10 comprises a transfer box 11 and a transfer piece 12 arranged in the transfer box 11. The transfer box 11 can have a cylindrical structure and has a first opening 111 and a second opening 112 at opposite ends thereof in the extending direction thereof. The first opening 111 and the second opening 112 can have the same or similar shape and area. The transfer box 11 can have a support frame to have a height suitable for operation.

[0064] Optionally, the first opening 111 of the transfer box 11 can be in communication with a battery processing equipment, which can be a vacuum oven or other equipment required for manufacturing a battery. That is, one end of the transfer box 11 can be in abutment with the battery processing equipment, or at least part of the structure of the end can be used as part of the battery processing equipment.

[0065] The transfer box 11 encloses a cavity having the first opening 111 and the second opening 112. The cavity has the transfer piece 12 arranged therein. At least part of the structure of the transfer piece 12 is movable along the extending direction of the transfer box 11 to move a battery device to be transferred.

[0066] The first cover plate assembly 20 is arranged at the first opening 111 and can be switched between an open state and a closed state. In the open state, the first cover plate 22 and the first opening 111 can be optionally staggered, and the orthographic projections of the two in the extension direction of the transfer box 11 can be optionally non-overlapping, so that the first opening 111 is completely open. In the closed state, at least part of the structure in the first cover plate assembly 20 abuts against the transfer box 11 and closes the first opening 111. The first cover plate assembly 20 and the transfer box 11 should have good sealing to reduce the possibility of gas leakage at the first opening 111 in the closed state.

[0067] Optionally, in the embodiment in which the first cover plate assembly 20 is in communication with the battery processing equipment, a mechanical arm can be arranged on one side of the first opening 111. The battery device is placed into the transfer box 11 by the mechanical arm through the first opening 111, so as to improve the processing efficiency and reduce the processing cost.

[0068] The second cover plate assembly 30 has a structure similar to that of the first cover plate 22, which will not be described here. The second cover plate assembly 30 is arranged at the end of the transfer box 11 away from the battery processing equipment, and can be used to take out the battery device from the battery transfer device 100 into the battery processing equipment. Therefore, the second cover plate assembly 30 can be arranged on the side closer to the operator.

[0069] Optionally, the second cover plate assembly 30 is configured to be able to be opened only when the first cover plate assembly 20 is in the closed state. That is, when the first cover plate assembly 20 is in the open state or in the process of switching the state, the second cover plate assembly 30 is locked in the closed state and cannot be opened. Therefore, the possibility of leakage of harmful substances in the battery processing equipment through the battery transfer device 100 can be reduced.

[0070] In the technical scheme of the embodiment of the application, the battery transfer device 100 includes a transfer assembly 10 for moving the position of the battery, and a first cover plate assembly 20 and a second cover plate assembly 30 arranged on both sides of the transfer assembly 10, respectively, for opening and closing two openings for the battery to enter and exit. One end of the transfer assembly 10 is provided with a first opening 111, which is in communication with the battery processing equipment. The battery can be moved from the processing environment to a relatively safe position convenient for taking out by the transfer assembly 10. At the same time, the second cover plate assembly 30 away from the processing equipment is configured to be able to be opened only in the closed state of the first cover plate assembly 20, thereby effectively reducing the possibility of leakage of harmful substances in the processing equipment and improving the safety of the operator.

[0071] In some optional embodiments, the first cover plate assembly 20 is configured to be able to switch to the open state under the condition that the second cover plate assembly 30 is in the closed state.

[0072] Similarly, the second cover plate assembly 30 can also lock the first cover plate assembly 20. Specifically, when the second cover plate assembly 30 is in the open state, the first cover plate assembly 20 cannot be opened, and only after the second cover plate assembly 30 is switched to the closed state, the first cover plate assembly 20 can be switched to the open state.

[0073] The specific implementation is the same as the above-mentioned locking of the first cover plate assembly 20 to the second cover plate assembly 30, and will not be repeated here.

[0074] By interlocking the first cover plate assembly 20 and the second cover plate assembly 30, the possibility of harmful substance leakage in the processing equipment can be further reduced, and the reliability of the battery transfer device 100 can be improved.

[0075] In some optional embodiments, the first cover plate assembly 20 includes a first sensor 21 configured to obtain the state of the first cover plate assembly 20; the second cover plate assembly 30 further includes a second sensor 31 configured to obtain the state of the second cover plate assembly 30; the transfer member 12 includes a first guide rail 121, a supporting member 122 movably connected with the first guide rail 121, and a plurality of third sensors 123 respectively arranged at opposite two end portions of the first guide rail 121, the third sensors 123 being configured to obtain the position of the supporting member 122 on the guide rail; the battery transfer device 100 further includes a controller, and the first sensor 21, the second sensor 31, and the third sensor 123 are respectively in communication connection with the controller.

[0076] Optionally, in order to realize the mutual locking function of the above-mentioned cover plate assemblies, sensors can be respectively arranged in the first cover plate assembly 20, the second cover plate assembly 30, and the transfer member 12. The first cover plate assembly 20 includes a first sensor 21, which can be a displacement sensor, a position sensor, a pressure sensor, a light sensor, etc., for determining whether the first cover plate assembly 20 is in a closed state or an open state, and sending corresponding signals to the controller according to the state, so that the controller can obtain the real-time state of the first cover plate assembly 20.

[0077] Similarly, the second cover plate assembly 30 can correspondingly be provided with a second sensor 31 for obtaining the state (open / closed) of the second cover plate assembly 30 and providing corresponding signals to the controller. The second sensor 31 and the first sensor 21 can be the same sensor, and are arranged at different positions in the two cover plate assemblies according to the opening mode of the first cover plate 22 and the second cover plate 32.

[0078] The transfer member 12 is used to move the battery device to be transferred from one of the first opening 111 and the second opening 112 to the other. Optionally, the transfer member 12 can include a first guide rail 121, a supporting member 122, and a third sensor 123. The first guide rail 121 can extend in parallel with the direction in which the first opening 111 points to the second opening 112. The supporting member 122 is arranged on the first guide rail 121 and can move back and forth along the first guide rail 121 under the action of a driving mechanism, which can be controlled by the controller.

[0079] The third sensor 123 is arranged on the first guide rail 121, for example, near the two end portions of the first guide rail 121 in the extending direction thereof, to determine whether the supporting member 122 has moved to the end portions. Alternatively, the third sensor 123 can be arranged at other positions in the transfer box 11 and determine the position of the supporting member 122 by image acquisition or the like. Alternatively, the third sensor 123 can be a displacement sensor such as a grating ruler and continuously extend along the extending direction of the first guide rail 121. The third sensor 123 can be of any suitable type as long as it can provide a corresponding signal to the controller when the supporting member 122 reaches the two ends of the guide rail.

[0080] The first, second, and third sensors are in communication connection with the controller, that is, they can perform remote signal transmission through the transmitting module and the receiving module, or they can be directly connected through wiring. The various sensors can adopt different connection modes according to their different arrangement positions.

[0081] The positions of the two side cover plate assemblies and the supporting member 122 for carrying the battery in the transfer assembly 10 can be conveniently obtained by arranging multiple sensors and the controller in communication connection with the sensors, so that the real-time state can be conveniently determined by the controller to realize the interlocking function.

[0082] In some optional embodiments, the controller is configured to control the first cover plate assembly 20 to be in the closed state when the second cover plate assembly 30 is in the open state or the supporting member 122 is not located at the end of the guide rail near the first opening 111. The controller is configured to control the second cover plate assembly 30 to be in the closed state when the first cover plate assembly 20 is in the open state or the supporting member 122 is not located at the end of the guide rail near the second opening 112.

[0083] According to the data collected by the first, second, and third sensors, the controller can determine the opening / closing states of the first cover plate assembly 20 and the second cover plate assembly 30 and the position of the supporting member 122 in the transfer member 12, and control the opening / closing of the cover plates accordingly.

[0084] Specifically, the controller can be configured to control the second cover plate assembly 30 to switch to the open state only when the first cover plate assembly 20 is in the closed state and the support 122 is located on the first guide rail 121 near one end of the second opening 112, i.e. both conditions are met. The opening of the second cover plate assembly 30 can be selected to be triggered by the operator through a button or switch, or can be automatically opened after the two conditions are met, or can be opened after the two conditions are met and last for a preset time.

[0085] Similarly, the controller can be configured to control the first cover plate assembly 20 to switch to the open state only when the second cover plate assembly 30 is in the closed state and the support 122 is located on the first guide rail 121 near one end of the first opening 111. The opening of the first cover plate assembly 20 can be triggered by the aforementioned battery processing equipment side, or can be opened after the conditions are met / preset time after the conditions are met.

[0086] Through the above-mentioned determination mode of the controller, the first and second cover plate assemblies on both sides of the transfer box 11 can be locked with each other, and the cover plate assembly on the other side can be opened only after the side is closed and the support 122 is moved into position, further improving the reliability of the battery transfer device 100 as a whole.

[0087] In some optional embodiments, the transfer assembly 10 further comprises a fourth sensor 13 arranged in the transfer box 11, the fourth sensor 13 is configured to obtain the concentration of harmful gas in the transfer box 11, and the fourth sensor 13 is in communication connection with the controller; the controller is configured to control the first cover plate assembly 20 and the second cover plate assembly 30 to be in the closed state when the concentration of harmful gas exceeds a preset threshold.

[0088] In addition to the aforementioned sensors, the transfer assembly 10 can also be provided with a fourth sensor 13, which is a gas concentration sensor. The sensor is arranged in the transfer box 11 and is configured to detect the concentration of a specific harmful substance. For example, the fourth sensor 13 can be used to detect the concentration of hydrogen sulfide gas in the transfer box 11.

[0089] The fourth sensor 13 can also be in communication connection with the controller and send a signal to the controller according to the detection result to represent whether the concentration of a specific gas in the transfer box 11 exceeds a preset threshold, and in the state of exceeding, the first cover plate assembly 20 and the second cover plate assembly 30 on both sides cannot be switched to the open state.

[0090] Optionally, the fourth sensor 13 can adopt a data acquisition mode of automatic detection at a certain time interval, and / or the fourth sensor 13 can adopt detection before each of the first cover plate assembly 20 and the second cover plate assembly 30 needs to be switched to the open state.

[0091] Therefore, on the basis of comprehensively considering the foregoing control logic, the first cover plate assembly 20 can be switched to the open state according to the request instruction of the operator or the automatic program when the three conditions that the second cover plate assembly 30 is in the closed state, the support 122 is located at one end close to the first opening 111, and the concentration of the harmful substance is lower than the preset threshold are all met; correspondingly, the second cover plate assembly 30 can be switched to the open state when the three conditions that the first cover plate assembly 20 is in the closed state, the support 122 is located at one end close to the second opening 112, and the concentration of the harmful substance is lower than the preset threshold are all met.

[0092] By directly detecting the concentration of the harmful gas in the transfer box 11 through the fourth sensor 13, the possibility of leakage of the harmful substance can be further reduced, and the reliability of the battery transfer device 100 can be improved.

[0093] In some optional embodiments, the first cover plate assembly 20 includes the first cover plate 22 and the driving member 23 connected to the first cover plate 22, and the second cover plate assembly 30 includes the second cover plate 32 and the locking member 33 matched with the second cover plate 32; the battery transfer device 100 further includes a controller, which is communicatively connected with the driving member 23, the transfer member 12, and the locking member 33, respectively.

[0095] Similarly to the first cover plate assembly 20, the second cover plate assembly 30 can include the second cover plate 32 and the locking member 33, which can be locked or unlocked with the second cover plate 32, in the locked state, the second cover plate 32 is kept in the closed state and cannot be opened, and after being unlocked, the second cover plate 32 can be opened manually by the operator or automatically by using a structure similar to the driving member 23.

[0096] Optionally, the driving member 23 and the locking member 33 can be in communication connection with a controller, so as to conveniently send a signal to the two components through the controller to switch the open / closed state, and facilitate the switching of the cover assembly between the open state and the closed state. In the embodiment provided with the aforementioned sensor, the controller can control the movement of the driving member 23 and the locking state of the locking member 33 according to the aforementioned control logic, so as to realize the mutual locking between the first cover assembly 20 and the second cover assembly 30.

[0097] Please refer to FIG. 6, which is an enlarged view of the region P shown in FIG. 2. In some optional embodiments, the driving member 23 comprises a first sub-driving member 231, a second sub-driving member 232 and a support plate 233, the first sub-driving member 231 is connected between the support plate 233 and the transfer box 11, the second sub-driving member 232 is connected between the support plate 233 and the first cover plate 22, and the first cover plate 22 is arranged on the side of the support plate 233 close to the transfer assembly 10.

[0098] The driving member 23 in the first cover assembly 20 is used to drive the first cover plate 22 to switch between the closed state and the open state. Optionally, the driving member 23 can adopt a structure comprising a first sub-driving member 231, a second sub-driving member 232 and a support plate 233, wherein the first sub-driving member 231 is used to realize the relative movement between the support plate 233 and the transfer box 11, and the second sub-driving member 232 is used to realize the relative movement between the support plate 233 and the first cover plate 22, so as to split the state switching of the first cover plate 22 into two parts of stroke, and make it have higher operation efficiency.

[0099] Specifically, the first sub-driving member 231 can be arranged on the side of the support plate 233 away from the transfer box 11, and the second sub-driving member 232 can be arranged on the side of the support plate 233 close to the transfer box 11, so as to reduce the possibility of mutual interference during the movement of the two. Moreover, the driving directions of the first sub-driving member 231 and the second sub-driving member 232 can be different, so as to conveniently switch the first cover plate 22 between the two states.

[0100] By arranging two sub-driving members 23 and a support plate 233 as an intermediate structure, the first cover assembly 20 can realize automatic opening or automatic closing, thereby improving the operation efficiency and reliability.

[0101] In some optional embodiments, the first sub-driving member 231 and the second sub-driving member 232 are both driving cylinders.

[0102] Optionally, the first sub-driving member 231 and the second sub-driving member 232 in the driving member 23 can be cylinders, and different cylinders can be selected according to the required stroke and force. The cylinder body of the first sub-driving member 231 can be fixed to the transfer box 11, and the piston rod thereof is connected to the side surface of the support plate 233 away from the transfer box 11 and can move in the second direction Y. Similarly, the cylinder body of the second sub-driving member 232 can be fixed to the side surface of the support plate 233 away from the transfer box 11, and the piston rod thereof is connected to the first cover plate 22 and can move in the first direction X.

[0103] Optionally, a valve corresponding to each cylinder can be arranged on the side surface of the support plate 233 away from the transfer box 11, which can be a commonly used control valve such as a three-position five-way electromagnetic valve, so as to be close to the position of the cylinder and facilitate connection.

[0104] By arranging the driving member 23 as a cylinder, the support plate 233 and the first cover plate 22 can move smoothly, and the specific stroke length of the two can be easily controlled.

[0105] In some optional embodiments, the first opening 111 and the second opening 112 are arranged on the opposite sides of the transfer box 11 in the first direction X, the first sub-driving member 231 can drive the support plate 233 to move relative to the transfer box 11 in the second direction Y intersecting the first direction X, and the second sub-driving member 232 can drive the first cover plate 22 to move relative to the support plate 233 in the first direction X.

[0106] Optionally, the transfer box 11 and the transfer member 12 arranged in the transfer box 11 can extend in the first direction X, and the first opening 111 and the second opening 112 are arranged on the opposite side end surfaces of the transfer box 11 in the direction, and can extend in a plane intersecting the first direction X.

[0107] In the embodiments provided with the first sub-driving member 231 and the second sub-driving member 232, the support plate 233 can be driven by the first sub-driving member 231 to move relative to the transfer box 11 in the second direction Y intersecting the first direction X, and the two directions can be arranged perpendicular to each other. For example, the first direction X can be parallel or close to the horizontal direction, and the second direction Y can be parallel or close to the vertical direction.

[0108] Optionally, the first cover plate 22 can be driven by the second sub-driving member 232 to move relative to the support plate 233 in the first direction X, the first cover plate 22 is located between the first opening 111 and the support plate 233, and can be switched between the state of abutting against the first opening 111 and the state of being separated from the first opening 111 in the first direction X.

[0109] Optionally, when switching from the closed state to the open state, the first cover plate 22 can be first moved away from the side of the transfer box 11 along the first direction X, and then the support plate 233 is moved along the second direction Y to be offset from the first opening 111. When switching from the open state to the closed state, the above steps can be implemented in reverse, until the first cover plate 22 abuts against the transfer box 11 and closes the first opening 111.

[0110] By providing the support plate 233 and enabling the support plate 233 and the first cover plate 22 to move along different directions respectively, the maximum space volume required by the first cover plate assembly 20 during opening / closing can be reduced, and the operation is more stable, thereby improving the applicability and reliability of the battery transfer device 100.

[0111] In some optional embodiments, the transfer assembly 10 further comprises a connecting bracket 14, which is arranged at one end of the transfer box 11 close to the first opening 111 and offset from the first opening 111; and the first cover plate assembly 20 is arranged at the side of the connecting bracket 14 away from the transfer box 11.

[0112] Optionally, in order to facilitate the arrangement of the first cover plate 22, the transfer assembly 10 can further comprise a connecting bracket 14. The connecting bracket 14 is connected to one end of the transfer box 11, and the connection between the two can be welding connection, fastener connection or clamping, etc. The connecting bracket 14 can be a frame structure formed by a plurality of support rods connected to each other, so as to have good structural strength, or the connecting bracket 14 can be a plate-shaped member, so as to have a larger connectable area, or the connecting bracket 14 can include both structures.

[0113] The connecting bracket 14 can extend at least partially along the second direction Y to provide space for the support plate 233 moving along the direction to be connected. The connecting bracket 14 can extend from one end of the transfer box 11 along a plane or curved surface intersecting the first direction X, and is arranged offset from the first opening 111, that is, the orthographic projection of the connecting bracket 14 is offset from the orthographic projection of the first opening 111, and the orthographic projection of the connecting bracket 14 can be arranged at least partially above the orthographic projection of the first opening 111 or around the orthographic projection of the first opening 111, and there is a certain interval between the two, so as to reduce the possibility of the connecting bracket 14 interfering with the closed state of the first cover plate assembly 20.

[0114] The first cover plate assembly 20 is arranged at the side of the connecting bracket 14 away from the transfer box 11 and connected to the surface of the bracket, and the two can be connected by fasteners or welding, and the connection is stable and reliable.

[0115] The connection bracket 14 can provide more installation space for the first cover plate assembly 20, and make the connection between the first cover plate assembly 20 and the transfer assembly 10 more stable, and further make the switching of the first cover plate assembly 20 between the open state and the closed state more stable and more accurate in alignment with the first opening 111.

[0116] In some optional embodiments, the connection bracket 14 is provided with a second guide rail 141 extending along the second direction Y, and the support plate 233 is movably connected with the connection bracket 14 through the second guide rail 141.

[0117] In the embodiments in which the support plate 233 moves relative to the connection bracket 14 along the second direction Y, the support plate 233 and the connection bracket 14 can be connected by setting guide rails. Specifically, a second guide rail 141 extending along the second direction Y can be arranged on the side surface of the connection bracket 14 close to the first cover plate 22 along the first direction X, and further optionally a plurality of second guide rails 141 extending parallel to each other can be arranged. Correspondingly, the support plate 233 can be provided with a slider or a protruding end or other structure capable of cooperating with the second guide rail 141, so that the support plate 233 is movably connected with the connection bracket 14 through the second guide rail 141, and further the movement track of the support plate 233 is limited by the second guide rail 141.

[0118] Optionally, two second guide rails 141 can be arranged on the connection bracket 14, and the two second guide rails 141 extend parallel to each other and have the same or similar lengths. The two guide rails can be arranged at positions close to the two side edges of the support plate 233, respectively, and the first sub-driving member 231 is located between the two guide rails, so as to further make the support plate 233 move stably and uniformly. Here, the first sub-driving member 231 is arranged between the second guide rails 141, which means that the first sub-driving member 231 is located between the projections of the two second guide rails 141 along the first direction X.

[0119] By movably connecting the support plate 233 and the connection bracket 14 through the second guide rail 141, the movement of the support plate 233 can be more stable and less prone to misalignment, and further the accuracy of the alignment between the first cover plate 22 and the first opening 111 and the reliability of the first cover plate 22 in closing the first opening 111 in the closed state can be improved.

[0120] In some optional embodiments, the support plate 233 is provided with a plurality of linear bearings 234, and the side surface of the first cover plate 22 close to the support plate 233 is provided with a plurality of connecting ends 221 protruding, and the connecting ends 221 are arranged through the linear bearings 234.

[0121] In the embodiment provided with the second sub-driving member 232, the support plate 233 and the first cover plate 22 can be movably connected through the linear bearing 234. The linear bearing 234 has small friction and stable operation, and can obtain smooth linear motion with high sensitivity and precision, thereby improving the stability of the relative movement between the first cover plate 22 and the support plate 233.

[0122] Optionally, the support plate 233 can be provided with multiple linear bearings 234, which are uniformly distributed on the support plate 233 at different positions. For example, in the embodiment in which the support plate 233 is rectangular, each linear bearing 234 can be arranged near a corner, and each linear bearing 234 has the same parameters.

[0123] Correspondingly, the side surface of the first cover plate 22 near the support plate 233 can be provided with a connecting end 221, and the connecting end 221 can be matched with the linear bearing 234 in terms of position, shape and size, so that the connecting end 221 can pass through the linear bearing 234. For example, the cross section of each connecting end 221 can be circular, so that the connecting end 221 is easy to process and install.

[0124] By using the structure in which multiple linear bearings 234 and connecting ends 221 are matched with each other, the relative movement trajectory between the first cover plate 22 and the support plate 233 can be more stable, thereby further improving the reliability of the first cover plate assembly 20.

[0125] In some optional embodiments, the battery transfer device 100 further comprises a first sealing member 40 and a second sealing member 50. In the closed state of the first cover plate assembly 20, the first sealing member 40 is clamped between the first cover plate 22 and the transfer box 11 and surrounds the first opening 111. In the closed state of the second cover plate assembly 30, the second sealing member 50 is clamped between the second cover plate 32 and the transfer box 11 and surrounds the second opening 112.

[0126] Optionally, in order to further improve the reliability of the two side cover plate assemblies in closing the corresponding openings in the closed state, the first sealing member 40 and the second sealing member 50 can be arranged at the two side ends, respectively. In the closed state, the first sealing member 40 is at least partially clamped between the first cover plate 22 and the transfer box 11. According to the area of the end of the transfer box 11 and the area of the first opening 111, the first sealing member 40 can be clamped between the first cover plate 22 and the wall of the transfer box 11. Alternatively, a flange structure can be arranged at the end of the transfer box 11, so that the first sealing member 40 is clamped between the first cover plate 22 and the flange. The first sealing member 40 can be connected to the transfer box 11 or connected to the first cover plate 22. The second sealing member 50 can be arranged in the same or similar manner as the first sealing member 40, which will not be described herein.

[0127] The first seal 40 and the second seal 50 can be made of rubber or other materials with certain elasticity and arranged in a ring shape. The orthographic projection of the two seals along the first direction X can surround the orthographic projection of the corresponding opening, respectively, to provide good sealing effect.

[0128] By clamping the seal between the cover plate and the opening, the sealing performance of the two-side cover plate assembly on the corresponding opening in the closed state can be further improved, and the possibility of collision and damage between the cover plate and the transfer box 11 when switching between the open and closed states can be reduced, thereby improving the reliability of the battery transfer device 100.

[0129] In some optional embodiments, the first seal 40 is arranged on the first cover plate 22, and the second seal 50 is arranged on the transfer box 11.

[0130] In the embodiment in which the two-side opening of the transfer box 11 is provided with a seal, on the side of the first opening 111 of the first cover plate 22 which can be automatically opened / closed by the driving member 23, the first seal 40 can be connected and arranged on the side of the first cover plate 22 facing the transfer box 11 and can move with the first cover plate 22. The second seal 50 can be arranged on the surface of the transfer box 11 facing the second cover plate 32. The first seal 40 and the second seal 50 can be connected by any one of the connection modes of adhesive connection, fastener connection, clamping, and crimping.

[0131] By arranging the first seal 40 on the first cover plate 22, the first opening 111 can be made more flat, reducing the possibility of scratching the battery transfer device 100 when placing the battery to be transferred therein. By arranging the second seal 50 on the transfer box 11, the position of the seal can be more secure and less likely to fall off or be damaged due to impact of the second cover plate 32 during opening and closing.

[0132] In some optional embodiments, the second cover plate 32 is rotationally connected with the transfer box 11, and the locking member 33 is arranged in the transfer box 11.

[0133] As described above, the first cover plate assembly 20 can be automatically opened or closed by arranging the driving member 23, and the second cover plate assembly 30 can be locked or released by the locking member 33 and manually opened or closed by the operator or assisted by a mechanical arm or other components. The second cover plate 32 can be connected with the transfer box 11 in a rotational connection mode, which can be connected by a hinge or other structure and can be opened laterally.

[0134] The locking member 33 is used to cooperate with the second cover plate 32 to realize locking or releasing of the second cover plate 32. The locking member 33 can be connected and cooperated with the side of the second cover plate 32 facing the transfer box 11 from the inner side of the transfer box 11. At the same time, the locking member 33 can be arranged in the transfer box 11 and located at a side far away from the rotation shaft of the second cover plate 32, so as to provide stable locking effect by smaller acting force and reduce the possibility of accidental opening of the second cover plate 32.

[0135] The arrangement of the second cover plate 32 in rotation connection with the transfer box 11 can facilitate opening of the second cover plate 32 under the operation of personnel and is not easy to hinder the removal of the battery. At the same time, the arrangement of the locking member 33 in the transfer box 11 can provide protection for the locking member 33 by the wall of the transfer box 11, reduce the possibility of accidental locking or accidental unlocking of the locking member 33 due to external impact and the like, and further improve the reliability of the whole battery transfer device.

[0136] In some optional embodiments, the transfer box 11 further comprises an air inlet 113 and an air outlet 114 arranged through the wall of the transfer box 11, and at least one of the air inlet 113 and the air outlet 114 is in communication with the air pump.

[0137] The battery transfer device 100 can be used to remove the battery from the processing equipment containing harmful substances and transport it to a predetermined position. In this process, in order to facilitate the exhaust of waste gas such as hydrogen sulfide that may exist, the transfer box 11 can be provided with an air inlet 113 and an air outlet 114, both of which are arranged through the wall of the transfer box 11 to communicate the external environment with the cavity in the box.

[0138] Optionally, the air inlet 113 and the air outlet 114 can have the same or similar size and can be any shape convenient for processing, such as rectangle, circle, etc. The air inlet 113 and the air outlet 114 can each be provided with a communication pipe and be in direct or indirect communication with the air pump, so as to send dry and pure gas into the transfer box 11 and exhaust harmful gas, so as to reduce the concentration of harmful gas in the transfer box 11.

[0139] In the embodiment in which the fourth sensor 13 is arranged in the transfer box 11, if it is detected that the concentration of harmful gas in the box exceeds the preset threshold, the air pump can be automatically or manually started or the power of the air pump can be increased, so as to reduce the concentration of harmful gas in the transfer box 11 until it is lower than the preset threshold, so as to achieve one of the prerequisites for switching the cover plate assembly to the open state.

[0140] After the air inlet and the air outlet are arranged on the wall of the transfer box 11, ventilation can be performed in the transfer box 11 through the air inlet, the air outlet and the air pump, further reducing the possibility of leakage of harmful substances and improving the reliability of the battery transfer device 100.

[0141] In some optional embodiments, the walls of the transfer box 11 are at least partially made of transparent material.

[0142] Optionally, the walls of the transfer box 11 can be provided with a region made of transparent material, which forms an observation window. The observation window can have a large area and optionally extends along the first direction X, so that the operator can conveniently obtain the position state of the conveying member and the opening and closing state of the opposite first cover plate assembly 20 through the observation window.

[0143] Optionally, the transfer box 11 can be cylindrical and have multiple walls. Taking the case where the cross section of the transfer box 11 is rectangular, the top wall and the two opposite side walls of the transfer box 11 can be simultaneously provided with observation windows. The first cover plate 22 and the second cover plate 32 can also be optionally provided with observation windows to facilitate observation of the running state inside the transfer box from different angles.

[0144] Optionally, the observation windows can be made of PMMA (Polymethyl Methacrylate), PC (Polycarbonate), PET (Polyethylene terephthalate), and other transparent materials with certain impact resistance and durability. The observation windows on the walls and the cover plates can be optionally made of the same material and have the same thickness to facilitate processing.

[0145] By providing the observation windows made of transparent material on the walls of the transfer box 11, the operator can conveniently obtain the specific running state inside the battery transfer device 100, which facilitates the determination of whether to send a request to open the door signal, and the determination of whether there are problems such as component damage and falling off, thereby improving the use efficiency and reliability of the battery transfer device 100.

[0146] In some optional embodiments, the minimum distance between the first opening 111 and the second opening 112 is greater than or equal to 800 mm.

[0147] The battery transfer device 100 is used to transport the battery from the processing equipment to a position convenient for the operator to take out. The distance moved by the transfer member 12 can be optionally designed according to parameters such as the shape and size of the processing equipment connected by the first opening 111 and the size of the space outside the equipment.

[0148] On this basis, the first opening 111 and the second opening 112 are respectively arranged at two opposite ends of the transfer box 11 in the first direction X, and the edges of the two openings can be optionally located in two mutually parallel planes, so that the shape of the transfer box 11 is more regular and convenient for processing. At the same time, the minimum distance between the first opening 111 and the second opening 112 in the first direction X can be optionally greater than or equal to 800 mm, so that the battery has a certain distance between the placement position and the taking-out position.

[0149] When the battery transfer device 100 is used and the second cover plate assembly 30 is opened, the battery can be manually taken out by the operator. In this process, the operator needs to stretch his arm into the transfer box 11. By arranging the first opening 111 and the second opening 112 to have a larger distance, the possibility that the operator mistakenly stretches his arm too long into the transfer box 11 and touches the opposite first cover plate assembly 20 can be reduced. Similarly, the possibility that the mechanical arm or other mechanical structure for taking and placing the battery is damaged can also be reduced. Thus, the possibility of safety problems when taking out the battery is correspondingly reduced, and the overall reliability of the battery transfer device 100 is improved.

[0150] The present application provides a battery transfer device 100, which includes a transfer assembly 10, a first cover plate assembly 20, and a second cover plate assembly 30. The transfer assembly 10 includes a transfer box 11 and a transfer piece 12 arranged in the transfer box 11. The transfer box 11 has a first opening 111 and a second opening 112 arranged at two opposite ends thereof, and the transfer piece 12 can move between the first opening 111 and the second opening 112. The first cover plate assembly 20 is arranged at the first opening 111, the first opening 111 is in communication with a battery processing equipment, and the first cover plate assembly 20 can be switched between an open state of opening the first opening 111 and a closed state of closing the first opening 111. The second cover plate assembly 30 is arranged at the second opening 112, and the second cover plate assembly 30 can be switched between an open state of opening the second opening 112 and a closed state of closing the second opening 112. The second cover plate assembly 30 is configured to be switched to the open state under the condition that the first cover plate assembly 20 is in the closed state, and the first cover plate assembly 20 is configured to be switched to the open state under the condition that the second cover plate assembly 30 is in the closed state.

[0151] The battery transfer device 100 further includes a controller configured to control the first cover plate assembly 20 to be in the closed state when the second cover plate assembly 30 is in the open state or the support piece 122 is not located at one end of the guide rail close to the first opening 111. The controller is configured to control the second cover plate assembly 30 to be in the closed state when the first cover plate assembly 20 is in the open state or the support piece 122 is not located at one end of the guide rail close to the second opening 112.
