Referring to fig. 1 and 2, in one embodiment, the conveying apparatus includes a tray circulation mechanism 2, where the tray circulation mechanism 2 is used to transfer the tray mechanism 1 and the pole core assembly 01, and the tray mechanism 1 is movable on the tray circulation mechanism 2 along a first direction.

In this specific example, during the feeding of the pole core body 010, the pole core assembly 01 moves in the first direction on the tray circulation mechanism 2 following the tray mechanism 1, and the tray circulation mechanism 2 has the conveying line 21 extending in the first direction; when the pole core assembly 01 moves to a designated station on the material disc circulation mechanism 2 along with the material disc mechanism 1, a subsequent carrying process is carried out on the pole core assembly 01.

Referring to fig. 1 and 2, in one embodiment, the conveying apparatus further includes a first conveying mechanism 3, a first carrying mechanism 4, and a discharging mechanism 5,

the first conveying mechanism 3 and the tray circulating mechanism 2 are arranged at intervals along the second direction, the first conveying mechanism 3 is provided with an input end and an output end which are distributed along the first direction, and the first conveying mechanism 3 is used for conveying the pole core body 010;

the first conveying mechanism 4 comprises a first clamping piece 41 and a first absorption piece 42 arranged beside the first clamping piece 41; the first clamping piece 41 clamps the pole core assembly 01 from the tray mechanism 1, the first carrying mechanism 4 carries the pole core assembly 01 to the input end of the first conveying mechanism 3 under the drive of the robot, the first clamping piece 41 releases the pole core assembly 01 and the first absorbing piece 42 absorbs the first protection piece 011, the first carrying mechanism 4 transfers the first protection piece 011 under the drive of the robot, and the pole core body 010 enters the input end of the first conveying mechanism 3 together with the second protection piece 012;

the blanking mechanism 5 is configured to move the pole core body 010 to a blanking station and transfer the second protection piece 012.

In this specific example, after the pole core assembly 01 moves to a designated station on the tray circulation mechanism 2 following the tray mechanism 1, the first conveying mechanism 4 is responsible for conveying the pole core assembly 01 from the tray mechanism 1 to the first conveying mechanism 3; in this process, the pole core assembly 01 is handled as a whole. The pole core assembly 01 specifically comprises a pole core body 010, and a first protection piece 011 and a second protection piece 012 for protecting the pole core body 010; along the thickness direction of the pole core body 010, a first protection piece 011 is arranged on the upper side of the pole core body 010 in a covering manner, and a second protection piece 012 is arranged on the lower side of the pole core body 010 in a covering manner. Because the first carrying mechanism 4 carries the pole core body 010 together with the protection sheet, the pole core body 010 is protected by the protection sheet in the carrying process, so that the damage of the pole core body 010 can be effectively prevented, the cost is saved, and the production efficiency is improved.

Further, the first suction member 42 in the first conveyance mechanism 4 may suck the first protection sheet 011 while the first clamping member 41 in the first conveyance mechanism 4 clamps the pole core assembly 01; alternatively, while the first clamping member 41 clamps the pole core assembly 01 from the tray mechanism 1, the first absorbing member 42 is absorbed on the first protection sheet 011, so that not only the stability of the first carrying mechanism 4 for carrying the pole core assembly 01 can be improved, but also the subsequent transfer of the first protection sheet 011 is facilitated. When the first carrying mechanism 4 carries the pole core assembly 01 to the input end of the first conveying mechanism 3 under the driving of the robot and the first clamping member 41 releases the release pole core assembly 01, the first absorbing member 42 absorbs the first protection sheet 011, so that the first protection sheet 011 is separated from the pole core body 010, only the pole core body 010 and the second protection sheet 012 enter the input end of the first conveying mechanism 3, and the first carrying mechanism 4 transfers the first protection sheet 011 under the driving of the robot.

Finally, the pole core body 010 and the second protection piece 012 are separated by the blanking mechanism 5, and only the pole core body 010 is moved to the blanking station, and the second protection piece 012 is transferred.

Therefore, while the first conveying mechanism 4 conveys the pole core assembly 01 from the tray mechanism 1 to the first conveying mechanism 3, the first protection piece 011 and the second protection piece 012 are connected with the pole core body 010 to protect the pole core body 010, but the subsequent pole core body 010 is not affected to enter the blanking station independently.

The first conveying mechanism 4 has both the functions of conveying the pole core assembly 01 and transferring the first protection sheet 011, and the discharging mechanism 5 has both the functions of discharging the pole core body 010 and transferring the second protection sheet 012; thereby improving the production efficiency and reducing the production line switching cost.

Further, the first carrying mechanism 4 includes a first main body 40, and the first clamping member 41 is disposed on the first main body 40, and the driving end of the robot driving the first carrying mechanism 4 is in butt joint with the first main body 40.

In the above process, the first protection sheet 011 located above the core body 010 has been removed, and the core body 010 enters the input end of the first conveying mechanism 3 together with the second protection sheet 012 located below it; if the second protection sheet 012 is kept in a state of being located below the pole core body 010 all the time, it is inconvenient for the blanking mechanism 5 to separate the second protection sheet 012 from the pole core body 010, and therefore, in this specific example, by providing the turning mechanism 6 between the input end and the output end of the first conveying mechanism 3, the turning mechanism 6 turns the pole core body 010 together with the second protection sheet 012 to a state in which the second protection sheet 012 is located above the pole core body 010, so that it is possible to facilitate the subsequent blanking mechanism 5 to separate the second protection sheet 012 from the pole core body 010 and transfer the second protection sheet 012.

When the blanking mechanism 5 conveys the pole core body 010 and the second protection piece 012 to the blanking station under the driving of the robot, and the second clamping piece 51 releases the pole core body 010 and the second protection piece 012, the second absorbing piece 52 absorbs the second protection piece 012, so that the second protection piece 012 is separated from the pole core body 010, only the pole core body 010 enters the blanking station, and the blanking mechanism 5 transfers the second protection piece 012 under the driving of the robot. The blanking station can be, for example, the equipment station of the next working procedure.

In this specific example, the overturning driving member 61 drives the rotating shaft 62 to rotate, the clamping assembly 63 disposed on the rotating shaft 62 rotates along with the rotating shaft 62, and the clamping assembly 63 further drives the pole core body 010 clamped by the clamping assembly and the second protection piece 012 to rotate together, so that the second protection piece 012 is switched from a state located below the pole core body 010 to a state located above the pole core body 010, thereby facilitating the subsequent blanking mechanism 5 to separate the second protection piece 012 from the pole core body 010 and transfer the second protection piece 012.

Alternatively, as shown in fig. 4, a plurality of pole core assemblies 01 are stacked to form one pole core module, and four such pole core modules may be placed on one tray body 11; and, two pole core modules are arranged near one side of the material disc body 11, and two pressing assemblies 12 can be arranged corresponding to the two pole core modules; the other two pole core modules are arranged close to the other side of the material disc body 11, and two pressing assemblies 12 are also arranged corresponding to the two pole core modules.

In this specific example, the robot is docked to the connection frame 91 of the partition taking mechanism 9 to move the partition taking mechanism 9, and the third suction member 92 in the partition taking mechanism 9 is used to suck the partition 02. Optionally, a plurality of third suction members 92 may be provided on the connection frame 91 to improve the efficiency of moving the partition 02; for example, the number of third absorbent members 92 is four, two of the third absorbent members 92 being disposed on one side and the other two third absorbent members 92 being disposed on the other side; for convenience of description, the above one side is referred to as a left side and the other side is referred to as a right side. After the circulation is started, the robot drives the baffle taking mechanism 9 to move to the baffle caching mechanism 10, each third adsorption piece 92 adsorbs one baffle, then the robot drives the baffle taking mechanism 9 to move to the empty tray mechanism 1 on the tray circulation mechanism 2, the two third adsorption pieces 92 on the right side firstly loosen the release baffle to the right side of the tray mechanism 1, at the moment, the two third adsorption pieces 92 on the left side keep the state of adsorbing the baffle, then the robot drives the baffle taking mechanism 9 to translate to the right wholly, the two third adsorption pieces 92 on the left side translate to the right side of the tray mechanism 1, and the two third adsorption pieces 92 on the left side loosen the release baffle to the right side of the tray mechanism 1.

All the partition plates 02 are concentrated on the right side of the empty tray mechanism 1, because the pressing assembly 12 in the tray mechanism 1 has certain requirements on the thickness of the material when pressing the material, and the pressing assembly 12 can press the material only when the thickness meets the requirements; therefore, the partition plates are all concentrated on the right side of the empty tray mechanism 1, so that the pressing assembly 12 can press the partition plates, and circulation is smoothly performed.

Referring to fig. 1 and 2, in one embodiment, the pole core conveying system further includes a second conveying mechanism 8, where the second conveying mechanism 8 is disposed beside the output end of the second conveying mechanism 7; the second conveying mechanism 8 is used for transferring the protection sheet from the output end of the second conveying mechanism 7 to the empty tray mechanism 1 on the tray circulating mechanism 2.

In this specific example, the second conveying mechanism 8 is provided to convey the protection sheet, and the protection sheet is transferred from the output end of the second conveying mechanism 7 to the empty tray mechanism 1 on the tray circulation mechanism 2, so that the protection sheet is recycled.

Referring to fig. 10, in one embodiment, the second handling mechanism 8 includes a driving module 81, a first adsorbing module 82, and a second adsorbing module 83; the first adsorption module 82 and the second adsorption module 83 are connected with the driving module 81, and the driving module 81 can drive the first adsorption module 82 and the second adsorption module 83 to move along the second direction;

the first adsorption module 82 moves to the output end of the second conveying mechanism 7 under the driving action of the driving module 81 and adsorbs the protection sheet, the first adsorption module 82 and the protection sheet move to the empty tray mechanism 1 under the driving action of the driving module 81, and the protection sheet is released to the empty tray mechanism 1;

the second adsorption module 83 is used for adsorbing the protection sheet and moving the protection sheet from one side to the other side of the empty tray mechanism 1 under the driving action of the driving module 81.

In this particular example, the first suction module 82 includes a first electric cylinder and a first suction cup; when the protective sheet is required to be carried, the first adsorption module 82 moves towards the second conveying mechanism 7 along the second direction under the driving action of the driving module 81 and reaches the output end of the second conveying mechanism 7, the first electric cylinder drives the first sucker to descend and the first sucker adsorbs the protective sheet, and then the first electric cylinder drives the first sucker to ascend; then the first adsorption module 82 moves away from the second conveying mechanism 7 along the second direction under the driving action of the driving module 81 and reaches the empty tray mechanism 1 on the tray circulating mechanism 2 together with the protection sheet, the first electric cylinder drives the first sucker to descend and the first sucker releases the protection sheet to the empty tray mechanism 1, then the first electric cylinder drives the first sucker to ascend, and the first adsorption module 82 returns to the initial position under the driving action of the driving module 81.

Optionally, two first suction cups may be disposed on the first suction module 82 to improve the efficiency of handling the protection sheet; one of the first suckers is arranged on the left side, and the other first sucker is arranged on the right side. The first suction cup on the left side adsorbs a protection sheet and places the protection sheet on the left side of the empty tray mechanism 1, and the first suction cup on the right side adsorbs a protection sheet and places the protection sheet on the right side of the empty tray mechanism 1.

However, as above, since the pressing assembly 12 in the tray mechanism 1 has a certain requirement on the thickness of the material when pressing the material, the pressing assembly 12 can press the material only when the thickness meets the requirement; therefore, when the protection sheets are placed at the empty tray mechanism 1, it is necessary to concentrate all the protection sheets to one side of the tray mechanism 1, for example, to the right side of the tray mechanism 1. Therefore, the protection sheet on the left side of the empty tray mechanism 1 needs to be moved from the left side to the right side of the tray mechanism 1 under the adsorption action of the second adsorption module 83 and the driving action of the driving module 81, so as to ensure that the pressing assembly 12 can press the protection sheet. Optionally, the second suction module 83 includes a second electric cylinder and a second suction cup, and the second electric cylinder can drive the second suction cup to descend or ascend.
