[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] like Figure 1 As shown, a plurality of storage units 101 are arranged in the container 100, and a unit door 102 for opening and closing the storage unit is hinged at the opening of each storage unit 101.

[0045] Manually opening or closing the unit door 102 is inefficient and increases labor costs. To this end, the present application provides a container automatic door opening device, which can automatically open or close the unit door 102 on the container 100, thereby improving the opening and closing efficiency of the unit door 102 and reducing labor costs.

[0046] like Figure 1 to Figure 2 As shown, the automatic door opening device for a container in the embodiment of the present application comprises a frame 1, a first transverse moving module 2 and a door opening mechanism 3, wherein: the first transverse moving module 2 is arranged on the frame 1, and the door opening mechanism 3 is slidably connected to the frame 1 and connected to the movable part of the first transverse moving module 2. The first transverse moving module 2 is used to drive the door opening mechanism 3 to move along a first horizontal direction (such as Figure 1 The door opening mechanism 3 is used to open or close the unit door 102 of the storage unit 101.

[0047] The optional working process of the automatic container door opening device in the embodiment of the present application is as follows:

[0048] First, the empty container 100 is transferred to the side of the rack 1 by a traveling device 200 (such as an AGV).

[0049] The first transverse moving module 2 drives the door opening mechanism 3 to move to the outside of a storage unit 101. The door opening mechanism 3 then opens the unit door 102 of the storage unit 101 to open the storage unit 101.

[0050] Subsequently, a packing device (such as a robot) loads the materials (such as battery packs) into the storage unit 101 . After the storage unit 101 is full, the door opening mechanism 3 immediately closes the unit door 102 .

[0051] Next, the first transverse movement module 2 drives the door opening mechanism 3 to move to the outside of the next storage unit 101 , and the door opening mechanism 3 cooperates with the packing device to pack the next storage unit 101 .

[0052] It can be seen that the automatic door opening device for a container in the embodiment of the present application realizes the automatic opening or closing of the unit doors on the container, thereby improving the opening and closing efficiency of the unit doors and reducing labor costs.

[0053] The first transverse movement module 2 can adopt various existing linear drive modules that can drive the door opening mechanism 3 to slide on the frame 1 along the first horizontal direction.

[0054] like Figure 3 As shown, optionally, the door opening mechanism 3 includes a support seat 31, a second transverse moving module 32, a fixed plate 33, a rotating module 34 and a suction door assembly 35, wherein: the support seat 31 is slidably mounted on the frame 1 along a first horizontal direction and is connected to the movable part of the first transverse moving module 2. The second transverse moving module 32 is arranged on the support seat 31, the fixed plate 33 is connected to the movable part of the second transverse moving module 32, the rotating module 34 is connected to the fixed plate 33, the suction door assembly 35 is connected to the movable part of the rotating module 34, and the suction door assembly 35 is used to suck the unit door 102. The second transverse moving module 32 is used to drive the suction door assembly 35 to move along a second horizontal direction perpendicular to the first horizontal direction (such as Figure 3 The second transverse moving module 32 and the rotating module 34 cooperate to drive the unit door 102 sucked by the suction door assembly 35 to rotate relative to the storage unit 101.

[0055] Taking the opening of the unit door 102 as an example, the working process of the door opening mechanism 3 is as follows: first, the second transverse moving module 32 drives the suction door assembly 35 to translate toward the storage unit 101, so that the suction door assembly 35 contacts and adsorbs on the unit door 102. Then, the second transverse moving module 32 drives the suction door assembly 35 to translate away from the storage unit 101, and synchronously, the rotating module 34 drives the suction door assembly 35 to rotate away from the storage unit 101, thereby implementing the opening of the unit door 102.

[0056] As shown in 3, optionally, the second transverse movement module 32 includes a first translation driving member 321, a moving seat 322 and a second translation driving member 323, wherein: the moving seat 322 is slidably mounted on the support seat 31 along the second horizontal direction, and is in driving connection with the movable part of the first translation driving member 321 disposed on the support seat 31, and the first translation driving member 321 is used to drive the moving seat 322 to translate along the second horizontal direction. The second translation driving member 323 is disposed on the moving seat 322, the fixed plate 33 is connected to the movable part of the second translation driving member 323, and the second translation driving member 323 is used to drive the fixed plate 33 to translate along the second horizontal direction.

[0057] The driving stroke and driving speed of the first translation driver 321 can be set to be greater than the driving stroke and driving speed of the second translation driver 323. In this way, when the unit door 102 needs to be opened and closed, the first translation driver 321 first quickly drives the suction door assembly 35 to move close to the unit door 102, and then the second translation driver 323 drives the suction door assembly 35 slowly to ensure that the suction door assembly 35 can be slowly and stably adsorbed on the unit door 102. The first translation driver 321 can be, for example, a rodless cylinder, and the second translation driver 323 can be a rod cylinder.

[0058] Optionally, the support seat 31 is also provided with a slide rail 36 extending along the second horizontal direction, and the mobile seat 322 is slidably connected to the slide rail via a slider. By providing the slide rail, the translation guidance of the mobile seat 322 is achieved to prevent the mobile seat 322 from going off track.

[0059] like Figure 4 and Figure 5 As shown, optionally, the rotating module 34 includes a third translation driving member 341, a rack 342, a rotating shaft 343 and a gear 344, wherein: the third translation driving member 341 is arranged on the fixed plate 33, and the rack 342 is fixedly connected to the driving end of the third translation driving member 341. The rotating shaft 343 is rotatably connected to the fixed plate 33, the gear 344 is fixedly installed at the upper end of the rotating shaft 343 and meshes with the rack 342, and the suction door assembly 35 is installed at the lower end of the rotating shaft 343. The third translation driving member 341 is used to drive the rack 342 to translate, so as to drive the gear 344, the rotating shaft 343 and the suction door assembly 35 to rotate synchronously.

[0060] The transmission structure composed of the rack 342 and the gear 344 has the advantages of high driving stability and strong driving force, which can ensure that the rotating module 34 can drive the suction door assembly 35 to rotate stably.

[0061] Optionally, the third translation drive member 341 is a cylinder. When the suction door assembly 35 sucks the unit door 102, the cylinder is de-energized, and the air cavity of the cylinder is connected to the outside. When the suction door assembly 35 rotates outward with the unit door 102, the gear 344 will drive the rack 342 to slide in the opposite direction, and the de-energized cylinder will not hinder the sliding of the rack 342, so that when the unit door 102 is opened, the suction door assembly 35 rotates synchronously with the unit door 102. When the battery pack fills the storage unit 101, the cylinder resumes air supply, and the third translation drive member 341 starts to work, driving the rack to reset, so that the meshed gear 344 rotates in the opposite direction to reset, and the unit door 102 is closed. After that, the suction door assembly 35 is separated from the unit door 102 and moves to the next unit door 102 driven by the first transverse module 2.

[0062] Continue to refer Figure 4 and Figure 5 As shown, optionally, the suction door assembly 35 includes a bearing plate 351, a buffer connection 352, a buffer plate 353, a rotating connection 354, a rotating support 355 and an adsorption member 356, wherein: the bearing plate 351 is mounted on the movable part of the rotating module 34. The buffer plate 353 is telescopically mounted on the bearing plate 351 via the buffer connection 352. The rotating support 355 is rotatably mounted on the buffer plate 353 via the rotating connection 354. The adsorption member 356 is arranged on the rotating support 355.

[0063] By configuring the suction door assembly 35 in this way, when the suction member 356 contacts the unit door 102 under the translational drive of the second transverse module 32, the angle can be adaptively adjusted according to the pressure conditions, ultimately ensuring that the suction surface of the suction member 356 can be tightly attached to the unit door 102, thereby achieving the suction of the unit door 102.

[0064] Optionally, the buffer connector 352 includes a guide rod and a spring, wherein: one end of the guide rod is fixedly connected to the buffer plate 353, and the other end of the guide rod is movably connected to the bearing plate 351. The spring is sleeved on the guide rod, and the two ends of the spring are respectively abutted against the bearing plate 351 and the buffer plate 353. When the adsorption member 356 contacts the unit door 102, the spring is compressed and shrinks and pushes the adsorption member 356 in the reverse direction, so that the adsorption member 356 is elastically pressed against the unit door 102, and finally the adsorption force of the adsorption member 356 on the unit door 102 is ensured.

[0065] Continue to refer Figure 4 and Figure 5As shown, optionally, the rotating connecting member 354 includes a first hinge block 3541, a second hinge block 3542, a connecting shaft 3543 and a torsion spring 3544, wherein: the first hinge block 3541 is arranged on the buffer plate 353, the first hinge block 3541 is provided with a first hinge hole, the second hinge block 3542 is arranged on the rotating support 355, the second hinge block 3542 is provided with a second hinge hole matching the first hinge hole, and the connecting shaft 3543 is connected in the first hinge hole and the second hinge hole. The torsion spring 3544 is fixedly sleeved on the connecting shaft 3543, wherein the first torsion arm of the torsion spring 3544 abuts against the buffer plate 353, and the second torsion arm of the torsion spring 3544 abuts against the rotating support 355.

[0066] When the adsorption member 356 contacts the unit door 102 , if the adsorption surface of the adsorption member 356 is not completely adsorbed on the unit door 102 , the rotating support 355 generates adaptive deflection due to uneven pressure, and finally the adsorption surface of the adsorption member 356 is completely adsorbed on the unit door 102 .

[0067] The adsorption member 356 may be an electromagnet or a suction cup.

[0068] like Figure 4 As shown, the door opening mechanism 3 may further include a detection component 4 for detecting the position of the door suction component 35. The detection component 4 includes a sensor and a sensor sheet, one of which is mounted on the fixed plate 33, and the other of which is mounted on the bearing plate 351. When the suction component 35 opens or closes the unit door 102, the bearing plate 351 rotates relative to the fixed plate 33 under the drive of the rotating module 34, so that the sensor sheet moves relative to the sensor. In this way, the sensor obtains the position information of the suction component 35 by sensing the relative displacement of the sensor sheet.

[0069] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.
