[0003] In order to protect the battery pack and facilitate the inspection of the battery pack, each storage unit is closed by a hinged unit door. Therefore, the automatic device equipment usually needs to be equipped with an automatic door opening device to automatically open or close the unit door of the storage unit.

The transverse movement mechanism drives the door opening mechanism to move to the outside of a storage unit, and the unit door is opened by the door opening mechanism. However, after the existing automatic door opening device opens the unit door of the current storage unit, the door opening mechanism will interfere with the opened unit door. It is necessary to wait until the current storage unit is packed and the unit door is closed before opening the unit door of the next storage unit, which reduces work efficiency.

DETAILED DESCRIPTION

[0057] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0058] Energy storage battery packs are typically stacked in individual storage units within a container for ease of transport and management. Due to the heavy weight of the battery packs, they are typically loaded sequentially into the container's storage units using automated packing equipment.

[0059] In order to protect the battery pack and facilitate the inspection of the battery pack, each storage unit is closed by a hinged unit door. Therefore, the automatic device equipment usually needs to be equipped with an automatic door opening device to automatically open or close the unit door of the storage unit.

[0060] Existing automatic door opening devices usually include a transverse movement mechanism and a door opening mechanism. The transverse movement mechanism drives the door opening mechanism to move to the outside of a storage unit, and the unit door is opened by the door opening mechanism. However, after the existing automatic door opening device opens the unit door of the current storage unit, the door opening mechanism will interfere with the opened unit door. It is necessary to wait until the current storage unit is packed and the unit door is closed before opening the unit door of the next storage unit, which reduces work efficiency.

[0061] Therefore, this application proposes a container automatic door opening device, please refer to Figures 1 to 3 As shown, an automatic door opening device for a container proposed in an embodiment of the present application is used to automatically open or close a unit door 11 on a container 10. The container 10 is provided with a first horizontal direction ( Figure 1A plurality of storage units 12 are arranged in parallel (in the X direction in the middle), and a unit door 11 for opening and closing the storage unit 12 is hinged at the opening of each storage unit 12. The automatic container door opening device includes a frame 20, a first transverse moving module 30, a driving mechanism 40 and an adsorption component 50. The driving mechanism 40 is slidably mounted on the frame 20 along the first horizontal direction, the first transverse moving module 30 is mounted on the frame 20, the driving end of the first transverse moving module 30 is connected to the driving mechanism 40, the driving end of the driving mechanism 40 is connected to the adsorption component 50, the first transverse moving module 30 It is configured to drive the driving mechanism 40 to move along the first horizontal direction to drive the adsorption component 50 to move to the outside of any storage unit 12 of the container 10; the adsorption component 50 is configured to suck or release the unit door 11 of the storage unit 12, and the driving mechanism 40 is configured to drive the adsorption component 50 to approach or move away from the current storage unit 12 to open or close the unit door 11 adsorbed by the adsorption component 50. The driving mechanism 40 is also configured to drive the adsorption component 50 to rise and fall so that the adsorption component 50 avoids the open unit door 11 of the current storage unit 12.

[0062] Specifically, the first transverse moving module 30 can adopt various existing linear drive modules that can drive the driving mechanism 40 to slide on the frame 20 along the first horizontal direction. Preferably, the first transverse moving module 30 adopts a transverse moving module composed of a motor and a synchronous belt transmission assembly.

[0063] Specifically, two packing positions are arranged side by side along the first horizontal direction below the frame 20, each packing position is used to place a load-bearing component 21, the load-bearing component 21 is used to carry the container 10 to be packed, and the walking device 22 is used to carry and drive the load-bearing component 21 to move. During packing, the walking device 22 first carries and drives a group of load-bearing components 21 and containers 10 to move to one of the packing positions for packing, and then carries and drives the next group of load-bearing components 21 and containers 10 to move to another packing position, realizing the alternating loading of containers 10, ensuring that the container 10 at one of the packing positions is being packed, and improving the packing efficiency of the packing equipment.

[0064] The optional working process of the automatic container door opening device in the embodiment of the present application is as follows:

[0065] The carrier 21 and the empty container 10 it carries are transferred to the packing location by a traveling device 22 (e.g., an AGV);

[0066] The first transverse movement module 30 drives the adsorption assembly 50 to move to the outside of a storage unit 12 , and the driving mechanism 40 cooperates with the adsorption assembly 50 to open the unit door 11 of the storage unit 12 , thereby opening the storage unit 12 ;

[0067] A packing device (such as a robot) loads materials (such as battery packs) into the storage unit 12 . After the storage unit 12 is full, the driving mechanism 40 cooperates with the adsorption assembly 50 to close the unit door 12 .

[0068] It should be noted that: after the adsorption component 50 opens the unit door 11 of the previous storage unit 12, the first transverse movement module 30 and the driving mechanism 40 cooperate to move the adsorption component 50 to the outside of the next storage unit 12, and the driving mechanism 40 cooperates with the adsorption component 50 to open the unit door 11 of the next storage unit 12. There is no need to wait for the previous storage unit 12 to be full before opening the unit door 11 of the next storage unit 12.

[0069] It can be seen that the automatic container door opening device proposed in the present application realizes the automatic opening or closing of the unit door 11 of the container 10 through the cooperation of the first transverse moving module 30, the driving mechanism 40 and the adsorption component 50; at the same time, after the adsorption component 50 opens the current unit door 11, it can drive the adsorption component 50 to move to the next unit door 11 through the cooperation of the first transverse moving module 30 and the driving mechanism 40, and open the next unit door 11 without waiting for the current storage unit 12 to be packed, thereby improving the opening and closing efficiency of the unit door 11 of the container 10 and meeting the fast-paced operation requirements.

[0070] In one embodiment, the driving mechanism 40 includes a first mounting base 41, a second lateral movement module 42, a second mounting base 43 and a lifting drive assembly 44, wherein:

[0071] The first mounting base 41 is slidably mounted on the frame 20 along the first horizontal direction and is connected to the driving end of the first transverse module 30;

[0072] The second transverse moving module 42 is disposed on the first mounting base 41, the second mounting base 43 is connected to the driving end of the second transverse moving module 42, the lifting driving assembly 44 is mounted on the second mounting base 43, and the adsorption assembly 50 is escalably mounted on the second mounting base 43, the driving end of the lifting driving assembly 44 is connected to the adsorption assembly 50, and the adsorption assembly 50 is used to adsorb or release the unit door 11;

[0073] The second lateral movement module 42 is configured to drive the second mounting base 43 and the adsorption assembly 50 along the second horizontal direction ( Figure 1 The adsorption assembly 50 moves laterally in the Y direction toward or away from the storage unit 12 to drive the unit door 11 attracted by the adsorption assembly 50 to rotate relative to the storage unit 12. The lifting drive assembly 44 is configured to drive the adsorption assembly 50 to move up and down to avoid the opened unit door 11. The second horizontal direction is perpendicular to the first horizontal direction.

[0074] Specifically, the first mounting seat 41 is slidably mounted on the frame 20 via a guide assembly. The guide assembly may be a sliding pair consisting of a linear guide rail and a slider or a sliding pair consisting of a guide rod and a guide sleeve.

[0075] Taking opening the unit door 11 of the corresponding storage unit 12 as an example, the door opening process of the driving mechanism 40 and the adsorption component 50 is as follows: first, the second transverse movement module 42 drives the adsorption component 50 to move toward the current storage unit 12, so that the adsorption component 50 contacts and adsorbs on the unit door 11 of the current storage unit 12; then, the second transverse movement module 42 drives the adsorption component 50 to move horizontally away from the current storage unit 12, thereby implementing the opening of the unit door 11 of the current storage unit 12.

[0076] It should be noted that: after the unit door 11 of the current storage unit 12 is opened, the adsorption component 50 releases the unit door 11 of the current storage unit 12, the lifting drive component 44 drives the adsorption component 50 to rise to a preset height, and the first transverse movement module 30 drives the drive mechanism 40 to move horizontally to the top of the next storage unit 12, and the lifting drive component 44 then drives the adsorption component 50 down to the outside of the next storage unit 12 to open the unit door 11 of the next storage unit 12.

[0077] It can be seen that through the cooperation of the first mounting seat 41, the first transverse moving module 30, the second transverse moving module 42, the second mounting seat 43 and the lifting drive assembly 44, the adsorption assembly 50 adsorbs the unit door 11 and drives the unit door 11 to rotate relative to the storage unit 12, thereby implementing the opening or closing of the unit door 11; at the same time, after the unit door 11 of the current storage unit 12 is opened, it can drive the adsorption assembly 50 to move laterally and lift, so that the adsorption assembly 50 avoids the opened unit door 11 of the current storage unit 12 and moves to the next storage unit 12, and implements the door opening operation on the unit door 11 of the next storage unit 12, providing a driving mechanism 40 with a simple structure and stable and reliable operation.

[0078] See also Figure 1 、 Figure 3 and Figure 4 As shown, in one embodiment, the driving mechanism 40 also includes a rotation drive assembly 45, which is mounted on a second mounting base 43, and the adsorption assembly 50 is transmission-connected to the driving end of the rotation drive assembly 45, and the rotation drive assembly 45 is configured to drive the adsorption assembly 50 to rotate relative to the storage unit 12, and the second transverse module 42 and the rotation drive assembly 45 cooperate to drive the unit door 11 adsorbed by the adsorption assembly 50 to rotate relative to the storage unit 12.

[0079] Take opening the unit door 11 of the corresponding storage unit 12 as an example: when the driving mechanism 40 cooperates with the adsorption component 50 to open the unit door 11 of the corresponding storage unit 12, when the second transverse movement module 42 drives the adsorption component 50 to move horizontally away from the current storage unit 12, the rotation drive component 45 works synchronously to drive the adsorption component 50 to rotate away from the storage unit 12 to cooperate with the second transverse movement module 42 to open the corresponding unit door 11.

[0080] It can be seen that by providing the rotary drive assembly 45 , the adsorption assembly 50 always adapts to the opening angle relative to the storage unit 12 during the process of opening or closing the unit door 11 , thereby ensuring smooth opening or closing of the unit door 11 .

[0081] See also Figure 5 As shown, in one embodiment, the lifting drive assembly 44 includes a first driving member 440, a lifting plate 441 and a lifting rod 442, wherein: the lifting plate 441 can be lifted and lowered on the second mounting seat 43, the fixed end of the first driving member 440 is mounted on the second mounting seat 43, the driving end of the first driving member 440 is connected to the lifting plate 441, and the first driving member 440 is configured to drive the lifting plate 441 to rise and fall; the upper end of the lifting rod 442 is mounted on the lifting plate 441, and the lower end of the lifting rod 442 is fixedly connected to the adsorption assembly 50, and the first driving member 440 drives the lifting plate 441 to rise and fall, so as to drive the adsorption assembly 50 to rise and fall through the lifting rod 442.

[0082] Specifically, the first driving member 440 is a rodless cylinder.

[0083] Specifically, the lifting plate 441 is mounted on the second mounting seat 43 in a liftable manner through a sliding guide pair consisting of a linear guide rail and a slider. The linear guide rail is vertically fixed on the second mounting seat 43, and the slider is fixed on the lifting plate and sleeved on the linear guide rail.

[0084] Specifically, two travel limit switches 431 are installed on the second mounting seat 43 at intervals along the height direction. The two travel limit switches 431 are used to limit the lifting travel of the lifting plate 441 .

[0085] It can be seen that through the cooperation of the first driving member 440, the lifting plate 441 and the lifting rod 442, the lifting and lowering of the lifting rod 442 is realized, thereby driving the adsorption component 50 to rise and fall, providing a lifting driving component 44 with a simple structure and stable and reliable operation.

[0087] Specifically, the second driving member 450 is a motor.

[0088] Specifically, a groove extending along the length direction of the lifting rod 442 is provided on the side wall thereof, and a limit key that cooperates with the groove on the lifting rod 442 is provided on the driven wheel 452 .

[0089] It can be seen that through the cooperation of the second driving member 450, the driving wheel 451, the driven wheel 452 and the transmission belt 453, the lifting rod 442 is rotated relative to the second mounting seat 43, thereby driving the adsorption component 50 to rotate; a driving mechanism 40 is provided that uses the same lifting rod 442 to drive the lifting and rotation of the adsorption component 50, which simplifies the overall structure of the driving mechanism 40, has a compact structure, ingenious design and low cost.

[0095] It can be seen that through the cooperation of the guide rod and the spring 520, when the adsorption component 56 contacts the unit door 11, the spring 520 is compressed and contracts and pushes the adsorption component 56 in the reverse direction, thereby ensuring that the adsorption component 56 is elastically pressed on the unit door 11, and finally ensuring the adsorption force of the adsorption component 56 on the unit door 11, providing a buffer component 52 with a simple structure and easy implementation.

[0096] In one embodiment, the adsorption member 56 is a suction cup or an electromagnet.

[0097] By providing the adsorption member 56 , two adsorption and fixation methods for the unit door 11 are provided.

[0098] In one embodiment, a first detection component and a limiting component are provided on the rotating support 55, wherein: the first detection component is configured to detect whether the adsorption component 56 accurately adsorbs the unit door 11; the limiting component is configured to abut the unit door 11 before the adsorption component 56 contacts the unit door 11, so as to implement elastic limitation on the adsorption component 56.

[0099] Specifically, the first detection component includes two position sensors 550 , and the two position sensors 550 are respectively installed on both sides of the adsorption component 56 .

[0100] Specifically, the limiting assembly includes two groups of elastic buffers 551 . The two groups of elastic buffers 551 are respectively installed on both sides of the adsorption component 56 , and each group of elastic buffers 551 includes at least one elastic buffer 551 .

[0101] It can be seen that by setting the first detection component, automatic detection of whether the adsorption component 56 accurately adsorbs the unit door 11 is achieved; by setting the limiting component, elastic limitation of the adsorption component 56 is achieved before the adsorption component 56 contacts the unit door 11, thereby avoiding collision between the adsorption component 56 and the unit door 11 and causing damage to the adsorption component 56.

[0102] See also Figure 1 and Figure 4 As shown, in one embodiment, a second detection component 430 is provided on the second mounting base 43 , and the second detection component 430 is configured to perform photo detection on the unit door 11 to obtain position information of the unit door 11 .

[0103] Specifically, the second detection component 430 includes a camera, which takes a picture of the unit door 11 to obtain the position information of the unit door 11 .

[0104] It can be seen that by providing the second detection component 430 , automatic detection of the position of the unit door 11 is achieved, making it easier to control the door opening device to find the exact position of the unit door 11 .

[0105] The automatic container door opening device provided in the embodiment of the present application has the following advantages:

[0106] 1) After the current unit door is opened, the first transverse movement module and the driving mechanism cooperate to drive the adsorption component to move to the next unit door and open the next unit door without waiting for the current storage unit to be packed. This improves the opening and closing efficiency of the container unit door and meets the fast-paced operation requirements.

[0107] 2) A rotary drive assembly is provided so that when the unit door is opened or closed, the adsorption assembly follows the unit door and always adapts to the opening angle of the unit door relative to the storage unit, thereby ensuring smooth opening or closing of the unit door.

[0108] 3) The same lifting rod is used to drive the adsorption component to lift and rotate the driving mechanism, which simplifies the overall structure of the driving mechanism, has a compact structure, ingenious design and low cost.

[0109] 4) The adsorption component can implement adaptive adjustment of its own angle, ultimately ensuring that the adsorption surface of the adsorption component can be closely attached to the unit door, thereby achieving tight suction of the unit door.

[0110] 5) A first detection component is provided to automatically detect whether the adsorption member is accurately adsorbed on the unit door;

[0111] 6) A limit assembly is provided to prevent the adsorption component from colliding with the unit door when adsorbing the unit door, thereby causing damage to the adsorption component.

[0112] 7) A second detection component is provided to realize automatic detection of the position of the unit door.
