Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery production equipment, and particularly relates to a container door opening device. BACKGROUND

[0002] Energy storage batteries are generally stacked in each storage unit in a container for convenient transportation and management. Due to the heavy weight of the battery pack, the battery pack is generally sequentially loaded into each storage unit in the container by an automatic loading device.

[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 loading device usually needs to be provided with a door opening device to automatically open or close the unit door of the storage unit so as to load the battery pack into the container.

[0004] Since the unit door of the container is usually made of ferromagnetic material, the existing door opening device usually includes a driving mechanism and an electromagnet assembly. The driving mechanism drives the electromagnet assembly to adsorb the unit door and then drives the electromagnet assembly to rotate to open or close the adsorbed unit door. However, the track of the driving mechanism moving the adsorption assembly is preset by the staff according to the size of the unit door. When the preset track cannot completely match the actual moving track of the unit door, the electromagnet assembly will be offset relative to the unit door during the rotation of the electromagnet assembly driven by the unit door, resulting in that the electromagnet assembly falls off from the unit door, and the unit door cannot be rotated to the predetermined position. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0051] The energy storage battery pack is generally stacked in each storage unit in the container for convenient transportation and management. Since the battery pack is heavy, it is generally loaded into each storage unit in the container in sequence by automatic loading equipment.

[0052] 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 loading equipment usually needs to be provided with a door opening device to automatically open or close the unit door of the storage unit by the door opening device, so as to load the battery pack into the container.

[0053] Since the unit door of the container is usually made of ferromagnetic material, the existing door opening device usually includes a driving mechanism and an electromagnet assembly. The driving mechanism drives the electromagnet assembly to adsorb the unit door and then drives the electromagnet assembly to rotate to open or close the adsorbed unit door. However, the track of the driving mechanism moving the adsorption assembly is preset by the staff according to the size of the unit door. When the preset track cannot completely match the actual moving track of the unit door, the electromagnet assembly will be offset relative to the unit door during the rotation of the electromagnet assembly driven by the unit door, resulting in that the electromagnet assembly falls off from the unit door, so that the unit door cannot be rotated to the predetermined position.

[0054] Therefore, the present application provides a container door opening device.

[0057] It can be seen that the blocking member 45 is installed on the base 41 in a lifting manner, the first driving member 44 drives the blocking member 45 to lift to the first position or the second position, and the blocking part 43 provided in a lifting manner moves the blocking member 45 into or moves the blocking member 45 away from the space between the unit door 12 and the storage unit 11, which not only has simple structure and reasonable layout, but also enables the blocking member 45 to move into the space between the unit door 12 and the storage unit 11 when the unit door 12 and the storage unit 11 have a small included angle.

[0058] As an implementation form, the suction part 42 comprises a suction member 46 and a second driving member 47, the suction member 46 is configured to suck or release the front face of the unit door 12, the suction member 46 is installed on the base 41 in a lifting manner, the driving end of the second driving member 47 is connected with the suction member 46, the second driving member 47 is configured to drive the suction member 46 to lift to a third position or a fourth position, the third position is located above the unit door 12; when the suction member 46 is lifted to the third position, the suction member 46 moves away from the front face of the unit door 12; after the suction member 46 is lowered to the fourth position, the suction member 46 is opposite to the front face of the unit door 12 and is abutted on the unit door 12 under the driving of the driving mechanism 30, so as to suck the front face of the unit door 12.

[0059] It can be seen that through the cooperation of the driving mechanism 30, the second driving member 47 and the suction member 46, after the current unit door 12 is opened, the suction member 46 is first lifted to the third position and then moved to the next unit door, so that the next unit door is opened, without waiting for the completion of the containerization of the current storage unit 11; at the same time, after the current unit door 12 is opened, the suction member 46 is first lifted to the third position and then moved to the unit door 12 of the storage unit 11 with the battery pack, so that the opened unit door 12 of the storage unit 11 with the battery pack is closed, thereby improving the opening and closing efficiency of the unit door 12 of the container 10 and meeting the fast-paced operation requirements.

[0060] As an implementation form, the suction member 46 and the blocking member 45 are both suction cups or electromagnets, the blocking member 45 and the suction member 46 are arranged in mirror image symmetry with the base 41 as the center, and the blocking member 45 can suck or release the back face of the unit door 11 when abutting against the back face of the unit door 12.

[0061] It can be seen that by setting the suction member 46 and the blocking member 45 as suction cups or electromagnets, both faces of the corresponding unit door 12 are sucked and clamped during the opening or closing of the unit door 12, thereby greatly reducing the risk of the unit door 12 falling off the suction mechanism 40 and improving the stability and reliability of the unit door 12 during the opening or closing process; moreover, the unit door 12 can be opened to abut against the container 10, so as to as far as possible not to affect the subsequent containerization of the battery cell module.

[0065] It can be seen that through the cooperation of the first lifting module 440, the first cylinder 441 and the first lifting seat 442, the first driving member 44 for driving the blocking member 45 to lift is realized, which has the advantages of simple structure, stable and reliable operation and small space occupation; through the cooperation of the second lifting module 470, the second cylinder 471 and the second lifting seat 472, the second driving member 47 for driving the suction member 46 to lift is realized, which has the advantages of simple structure, stable and reliable operation and small space occupation.

[0079] Please refer to Figures 1 to 3 The general action process of the container door opening device for opening or closing the unit door 12 is as follows:

[0080] When the unit door 12 is opened:

[0081] S1, the driving mechanism 30 drives the adsorption mechanism 40 to move along the first horizontal direction, so as to move the adsorption mechanism 40 to the outside of any one of the unit doors 12 to be opened;

[0082] S2, the driving mechanism 30 drives the adsorption mechanism 40 to move along the second horizontal direction to the current storage unit 11, so as to move the adsorption mechanism 40 to the door opening position, at this time, the blocking piece 45 of the adsorption mechanism 40 is in the first position, the adsorption piece 46 is in the fourth position, and the front surface of the unit door 12 is adsorbed by the adsorption piece 46;

[0083] S3, the driving mechanism 30 drives the adsorption mechanism 40 to move along the second horizontal direction away from the current storage unit 11, drives the unit door 12 adsorbed by the adsorption piece 46 to rotate relative to the corresponding storage unit 11, and then opens the unit door 12 adsorbed by the adsorption piece 46 by a set angle (which can be the angle between the blocking piece 45 and the unit door 12 and the storage unit 11);

[0084] S4, the first driving piece 44 drives the blocking piece 45 to descend to the space between the unit door 12 and the storage unit 11, and adsorbs the back surface of the unit door 12 by the blocking piece 45;

[0085] S5, the driving mechanism 30 drives the adsorption mechanism 40 to continue to move along the second horizontal direction away from the current storage unit 11, so as to open the unit door 12 adsorbed by the blocking piece 45 and the adsorption piece 46 to a preset angle. During the opening of the unit door 11, if the unit door 12 falls off from the adsorption part 42, the blocking piece 45 can drive the fallen unit door 12 to continue to rotate.

[0086] It should be noted that, according to actual operation requirements, when the unit door 12 needs to be opened to the position close to the container 10; in step S5, the driving mechanism 30 drives the adsorption mechanism 40 to continue to move along the second horizontal direction away from the corresponding storage unit 11, before the adsorption piece 46 contacts the adjacent storage unit 11, the adsorption piece 46 releases the adsorbed unit door 11 and drives the adsorption piece 46 to rise to the third position by the second driving piece 47, and the unit door 12 is opened to the position close to the container 10 by the blocking piece 45.

[0087] Taking the opened unit door 12 close to the container 10 as an example, when the opened unit door 12 is closed:

[0088] S1, the driving mechanism 30 drives the adsorption mechanism 40 to move along the first horizontal direction, so as to move the adsorption mechanism 40 to the outside of any one of the unit doors 12 to be opened;

[0089] S2, the driving mechanism 30 drives the adsorption mechanism 40 to move along the second horizontal direction to close the current unit door 11, so that the blocking piece 45 of the adsorption mechanism 40 is in the second position, the adsorption piece 46 is in the third position, and the back of the unit door 12 is adsorbed by the blocking piece 45;

[0090] S3, the driving mechanism 30 drives the adsorption mechanism 40 to move along the second horizontal direction away from the current storage unit 11, so that the unit door 12 adsorbed by the blocking piece 45 rotates relative to the corresponding storage unit 11, and the unit door 12 adsorbed by the blocking piece 45 has a set angle (an angle for the adsorption piece 46 to drop to the fourth position) with the current storage unit 11;

[0091] S4, the second driving piece 47 drives the adsorption piece 46 to drop to a position opposite to the front of the unit door 12 and adsorbs the front of the unit door 12;

[0092] S5, the driving mechanism 30 drives the adsorption mechanism 40 to continue to move along the second horizontal direction away from the current storage unit 11, so that the unit door 12 adsorbed by the blocking piece 45 and the adsorption piece 46 rotates towards the corresponding storage unit 11, before the blocking piece 45 contacts the corresponding storage unit 11, the blocking piece 45 releases the back of the unit door 12 and moves to the first position by the first driving piece 44, the driving mechanism 30 drives the unit door 12 adsorbed by the adsorption piece 46 to continue to move towards the corresponding storage unit, until the unit door 12 is closed.

[0093] The container door opening device provided by the embodiment has the following advantages:

[0094] 1) After the unit door is separated from the adsorption part, the blocking piece can drive the separated unit door to continue to rotate, so as to ensure that the unit door is rotated to a predetermined position.

[0095] 2) The second driving piece drives the adsorption piece to ascend and descend, so that the current unit door is avoided, the next unit door is opened, or the unit door of the storage unit filled with battery packs is closed after the current unit door is opened, the opening and closing efficiency of the unit door of the container is improved, and the fast rhythm operation requirement is met.

[0096] 3) The double-sided adsorption and clamping of the corresponding unit door during the opening and closing of the unit door is realized, the risk of the unit door falling off the adsorption mechanism is greatly reduced, and the stability and reliability of the unit door during the opening and closing are improved.

[0097] 4) The blocking piece and the adsorption piece are in floating contact with the unit door, can adaptively adjust the angle of the blocking piece and the adsorption piece, and protect the blocking piece, the adsorption piece and the unit door.

[0098] 5) through the rotation of the driving assembly, the unit door in the process of opening or closing, the adsorption mechanism always follow the unit door to adapt to the opening angle of the unit door relative to the storage unit, to ensure the smooth opening or closing of the unit door.
