[0046] In new energy vehicles, the battery is a very important component for storing electrical energy for use by the electric motor. New energy vehicles refer to vehicles that use non-traditional fuels as energy, usually including electric vehicles and fuel cell vehicles. These vehicles usually use batteries or fuel cells to drive electric motors. However, the battery pole roll usually refers to the part of the battery polar material prepared in the form of a thin roll. The polar material of the battery usually includes positive and negative poles, which bear the functions of charge storage and release in the battery. These polar materials are often prepared in the form of a sheet or roll to increase their surface area and improve the performance of the battery. With the increasing application of roll-to-roll vacuum coating technology in emerging fields such as new energy power batteries, the size and weight of the roll material used by the roll coating machine have gradually expanded. A loading device for loading and unloading roll materials can be used for intelligent transportation of raw materials for new energy vehicle batteries, improving the production efficiency of new energy vehicle batteries. In the preparation process of new energy vehicle batteries, raw material rolls need to be continuously added and replaced. The device can achieve large-scale intelligent and accurate transfer of heavy materials through code programs, and realize the loading and unloading of battery pole rolls during the transfer process, to improve the processing and manufacturing efficiency of new energy vehicle batteries.

[0047] The embodiment of the present application discloses a loading device for loading and unloading roll materials.

[0048] Referring to Figure 1 A loading device for loading and unloading roll materials includes a gantry 1, a moving platform 2 is installed on the gantry 1, the moving platform 2 can reciprocate along the length direction of the gantry 1, the middle part of the moving platform 2 is connected with a mechanical arm 3, and the bottom of the mechanical arm 3 is fixed with a roll clamp 4 for loading roll materials. The roll clamp 4 loads the roll materials on the mechanical arm 3, and the mechanical arm 3 loaded with the roll materials moves on the gantry 1 through the moving platform 2, for moving the roll materials from one position to another position.

[0049] Referring to Figure 2 and Figure 3 , the roll clamp 4 includes a control box 5 and a loading shaft group, the control box 5 is fixed on the side of the mechanical arm 3 away from the moving platform 2, and the loading shaft group is installed on the control box 5. The loading shaft group is used for loading roll materials, and the inner diameter of the roll materials can be sleeved on any one of the loading shafts 6 in the loading shaft group. In order to facilitate the loading and unloading of the roll materials, the inner sides of each loading shaft 6 in the loading shaft group are movably connected with a tensioning mechanism 7 and a pushing mechanism 8. The tensioning mechanism 7 is used for tightening or loosening the roll materials, and after the roll materials are sleeved on the loading shaft 6, the tensioning mechanism 7 expands outward and abuts against the inner diameter of the roll materials, so as to form a tensioning force on the roll materials and fix the roll materials.

[0050] Specifically, as Figure 4As shown, the tensioning mechanism 7 includes a plurality of tensioning cylinders 11 fixedly installed in the loading shaft 6 and a movable block 12 movably installed on the side wall of the loading shaft 6, and the movable block 12 is fixed to the output end of the tensioning cylinder 11, and the movable block 12 is used to form a tensioning force on the roll when the output end of the tensioning cylinder 11 is pushed out. Firstly, when the tensioning mechanism 7 needs to fix the material, the output end of the tensioning cylinder 11 is pushed out, at this time, the movable block 12 is located outside the loading shaft 6, so that the movable block 12 abuts against the inner diameter of the roll, and the movable block 12 forms a tensioning force on the roll when the output end of the tensioning cylinder 11 is pushed out, so as to fix the position of the roll. Secondly, when the tensioning mechanism 7 needs to release the material, the output end of the tensioning cylinder 11 is retracted, and the movable block 12 is retracted towards the side of the loading shaft 6, so that the movable block 12 is embedded in the loading shaft, at this time, the fixation on the roll is released. In the case that the loading shaft 6 is loaded with the roll, the movement of the roll is limited by the tensioning mechanism 7, which is beneficial to improve the stability of the roll transportation.

[0051] In an embodiment, the loading shaft group includes a main loading shaft and a secondary loading shaft arranged reversely, that is, the main loading shaft is fixed on the side of the control box 5, and the secondary loading shaft is fixed on the side of the control box 5 away from the main loading shaft. The main loading shaft is mainly used to carry heavy rolls, and the secondary loading shaft can be used to carry used empty rolls, which is beneficial to improve the carrying efficiency of the empty rolls and the full rolls. The main loading shaft and the secondary loading shaft are both provided with the tensioning mechanism 7 and the material pushing mechanism 8, the tensioning mechanism 7 can be pushed out and close to the roll in the case that the roll is loaded, so as to limit the movement of the roll, and the material pushing mechanism 8 is used to push the roll away from the loading shaft 6.

[0052] It is worth noting that the mechanical arm 3, the control box 5 and the main loading shaft form a C-shaped structure, so that the roll can be located below the mechanical arm 3 during the carrying process, which is beneficial to balance the overall center of gravity. The secondary loading shaft is arranged on the back of the main loading shaft, which can further balance the overall center of gravity of the mechanical arm 3.

[0053] Referring to Figure 5 , the material pushing mechanism 8 includes a first material pushing assembly 9 and a second material pushing assembly 10, the first material pushing assembly 9 is installed on both sides of the loading shaft 6, and the second material pushing assembly 10 is installed on the tensioning mechanism 7. The specific steps of unloading the roll are as follows: after the tensioning mechanism 7 is retracted inward, the fixation on the roll is released, the roll is first pushed to the end of the loading shaft 6 by the first material pushing assembly 9, when the roll is pushed to the end of the loading shaft 6, the tensioning mechanism 7 is expanded outward and drives the second material pushing assembly 10 to pass through the side wall of the loading shaft 6, so that the second material pushing assembly 10 is located outside the loading shaft 6, and then the roll is pushed away from the loading shaft 6 by the second material pushing assembly 10.

[0054] Referring to Figure 5 and Figure 6The first pushing assembly 9 comprises a moving seat 13, a sliding groove 14, a guide block 15, a moving hole 16 and a first driving member 17. The moving seat 13 is installed on the loading shaft 6. The sliding groove 14 is formed on the loading shaft 6 and embedded with the moving seat 13, so that the moving seat 13 reciprocates along the length direction of the sliding groove 14. In order to control the running track of the moving seat 13, the guide block 15 is installed on the loading shaft 6 and parallel to the length direction of the sliding groove 14. The moving hole 16 is formed on the moving seat 13 and penetrated by the guide block 15. The moving seat 13 reciprocates along the length direction of the guide block 15, so that the moving seat 13 reciprocates along a straight line and the accuracy of the moving seat 13 is improved. The first driving member 17 is used to drive the moving seat 13 to slide along the length direction of the sliding groove 14.

[0055] In order to improve the accuracy of the moving seat 13, the first driving member 17 adopts a screw motor structure. The first driving member 17 comprises a gear set 18, a first driving motor 19, a first screw rod 20 and a driving hole 21. The gear set 18 is installed in the control box 5. The first driving motor 19 is installed in the loading shaft 6. The output end of the first driving motor 19 is fixed with the gear set 18, so that the first driving motor 19 can drive the gear set 18 to rotate. One end of the first screw rod 20 is fixed on the gear set 18. The other end of the first screw rod 20 is rotatably connected with the inner wall of the loading shaft 6. In an example, in order to reduce the friction between the loading shaft 6 and the first screw rod 20, a bearing is installed on the inner wall of the loading shaft 6. The first screw rod 20 is rotatably connected with the inner wall of the loading shaft 6 through the bearing. The driving hole 21 is formed on the moving seat 13 and penetrated by the first screw rod 20. The driving hole 21 is internally threaded for screwing with the first screw rod 20. The first driving motor 19 drives the gear set 18 to rotate, so as to drive the first screw rod 20 to rotate. Thus, the moving seat 13 is moved to the end of the loading shaft 6. The moving seat 13 protrudes from the surface of the loading shaft 6. During the movement, the moving seat 13 abuts against the roll and pushes the roll to the end of the loading shaft 6.

[0056] Specifically, when loading the roll, the first driving member 17 drives the moving seat 13 to move towards the side of the control box 5, so that the moving seat 13 is away from the end of the loading shaft 6, and the roll can be sleeved on the loading shaft 6. When unloading the roll, the first driving member 17 drives the moving seat 13 to be close to the roll. When the moving seat 13 abuts against the roll, the first driving member 17 drives the moving seat 13 to move away from the side of the control box 5, so that the moving seat 13 pushes the roll to the end of the loading shaft 6.

[0057] Referring to Figure 7The second pushing assembly 10 comprises a pushing block 22, a pushing rod 23 and a second driving member 24. The pushing block 22 is installed on the movable block 12 away from the control box 5. One end of the pushing rod 23 is fixed with the pushing block 22, and the other end of the pushing rod 23 is located in the inner cavity of the movable block 12 and can slide along the length direction of the movable block 12 to push the pushing block 22 to move away from the movable block 12. The second driving member 24 is installed in the inner cavity of the movable block 12 and is used to drive the pushing rod 23 to move.

[0058] The second driving member 24 adopts a screw rod motor structure, and comprises a second driving motor 25, a second screw rod 26, a sliding block 27, a threaded hole 28 and a fixed groove 29. The second driving motor 25 is installed in the inner cavity of the movable block 12. One end of the second screw rod 26 is fixedly connected with the output end of the second driving motor 25, and the other end of the second screw rod 26 is rotationally connected with the inner wall of the movable block 12. The sliding block 27 is installed in the inner cavity of the movable block 12 and can slide along the length direction of the second screw rod 26. The threaded hole 28 is formed in the sliding block 27 and penetrates through the second screw rod 26. The second screw rod 26 is threadedly connected with the threaded hole 28, so that the second driving motor 25 drives the second screw rod 26 to rotate, thereby realizing the reciprocating movement of the sliding block 27 along the length direction of the second screw rod 26. When the sliding block 27 moves away from the second driving motor 25, the sliding block 27 drives the pushing rod 23 to move away from the control box 5, so that the pushing rod 23 drives the pushing block 22 to push the roll away from the loading shaft 6. Through the cooperation of the screw rod motor structure, the moving speed and distance of the pushing block 22 can be controlled, and the accuracy of the roll transportation can be improved.

[0059] Specifically, when the first pushing assembly 9 moves the roll to the end of the loading shaft 6, the output end of the expansion cylinder 11 pushes out the movable block 12, so that the pushing block 22 penetrates out of the loading shaft 6 to abut against the roll. Then the second driving member 24 drives the pushing rod 23 to move, so that the pushing rod 23 drives the pushing block 22 to move away from the roll and pushes the roll away from the loading shaft 6. The roll is pushed to the end of the loading shaft 6 by the first pushing assembly 9, and then the roll is pushed away from the loading shaft 6 by the second pushing assembly 10, which can improve the situation that the existing pushing structure is difficult to completely separate the roll from the loading shaft 6.

[0060] In one embodiment, as shown in Figure 8As shown, a plurality of rolling elements 30 are mounted on the outer wall of the loading shaft 6, and the rolling elements 30 are in rotational connection with the loading shaft 6, and the rolling elements 30 partially protrude from the outer wall of the loading shaft 6. The rolling elements 30 can be rolling bearings, which are used to reduce the resistance of the roll material moving on the loading shaft 6. In the process of sleeving the roll material on the loading shaft 6, the rolling bearings are rotated under the pressure applied by the roll material, which is beneficial to improve the efficiency of moving the roll material to the designated position on the loading shaft 6.

[0061] In an embodiment, referring to Figure 8 and Figure 9 , a plurality of detection sensors 31 are mounted on the loading shaft 6, which are used to detect the current position of the roll material. The detection sensors 31 can be photoelectric sensors. When the roll material moves on the loading shaft 6, the signal of each detection sensor 31 will change, and according to the change of the signal of each detection sensor 31, it can be determined whether the roll material is loaded in place or whether the roll material is separated from the loading shaft 6. In order to further improve the stability of the roll material sleeved on the loading shaft 6, a retaining pin 32 is mounted on the loading shaft 6, and a driving cylinder 33 is mounted in the loading shaft 6, and the output shaft of the driving cylinder 33 is fixed with the retaining pin 32. When the roll material is loaded in place, the driving cylinder 33 is used to push out the retaining pin 32, and when the roll material is ready to be transferred, the driving cylinder 33 is used to recover the retaining pin 32.

[0062] Specifically, the detection sensor 31 and the retaining pin 32 are used in cooperation. When the detection sensor 31 detects that the roll material is loaded in place, the output shaft of the driving cylinder 33 is pushed out, thereby driving the retaining pin 32 to penetrate through the side wall of the loading shaft 6, so that the retaining pin 32 can limit the roll material and reduce the probability of the roll material separating from the loading shaft 6, thereby improving the stability of the roll material loaded on the loading shaft 6.

[0063] In an example, after the loading shaft 6 is sleeved with the roll material, the detection sensor 31 detects that the roll material is loaded in place, and then the tensioning mechanism 7 is driven to expand to fix the roll material, and then the retaining pin 32 is driven to penetrate through the side wall of the loading shaft 6 to limit the movement of the roll material along the length direction of the loading shaft 6. When it is necessary to unload the material, the retaining pin 32 is driven to be recovered, so that the retaining pin 32 is embedded in the loading shaft 6, and the tensioning mechanism 7 is tightened inwardly, and the roll material is pushed to the end of the loading shaft 6 by the first pushing assembly 9. The detection sensor 31 detects whether the roll material is located at the end of the loading shaft 6. If the roll material is located at the end of the loading shaft 6, the tensioning mechanism 7 is expanded outwardly, and the roll material is pushed away from the loading shaft 6 by the second pushing assembly 10. A plurality of detection sensors 31 are mounted on the loading shaft 6, which is beneficial to improve the accuracy of the operation of each actuator on the loading shaft 6, including but not limited to the tensioning mechanism 7 and the pushing mechanism 8.

[0064] In an embodiment, as Figure 8As shown, the scanning device 34 is installed on the control box 5, which can be installed at the bottom end of the control box 5, for identifying whether there is an object within a preset distance from the mechanical arm 3 or the control box 5, that is, whether there is an object entering a circular area with the control box 5 as the center and the preset distance as the radius. When the scanning device 34 identifies that the object is close to the control box 5, a warning signal is sent to the outside world, for indicating the staff to move the object away from the preset distance of the control box 5, which is beneficial to improve the safety of the device mechanism operation.

[0065] Further, the loading device may cause injury during operation. In this case, a safety area needs to be set to ensure that personnel will not accidentally contact these components. The areas monitored by the two scanning devices 34 are divided as safety areas, the safety areas are cut into rectangular areas, and the front and rear distances in the rectangular areas are divided into three small areas, that is, a warning area, a deceleration area and a danger area. The alarm is triggered when an obstacle is detected in the warning area, the loading device decelerates when an obstacle is detected in the deceleration area, and the loading device stops running when an obstacle is detected in the danger area. Each area can be adapted and cut according to the actual situation, and the area size can reach 36 groups of position switching and shielding, meeting the switching of the channel operation and the loading docking.

[0066] In an embodiment, light curtain projection lamps are installed on the opposite sides of the control box 5, which project the running double-side distance in real time, so that personnel can intuitively perceive the safe running position of the loading device, which is beneficial to improve the safety performance of the loading device during operation.

[0067] The implementation principle of the loading device for loading and unloading the coiled material is as follows: the mechanical arm 3 loaded with the coiled material moves on the gantry 1 through the moving platform 2, and the coiled material is moved from one position to another position. When the coiled material needs to be loaded, the coiled material is sleeved on the loading shaft 6, the expansion mechanism 7 expands outward and abuts against the inner diameter of the coiled material, the coiled material is fixed after the expansion mechanism 7 forms the expansion force on the coiled material. When the coiled material needs to be unloaded, the expansion mechanism 7 is tightened inward, the fixing of the coiled material is released, the coiled material is first pushed to the end of the loading shaft 6 by the first pushing assembly 9, when the coiled material is pushed to the end of the loading shaft 6, the expansion mechanism 7 expands outward and drives the second pushing assembly 10 to pass through the side wall of the loading shaft 6, so that the second pushing assembly 10 is located outside the loading shaft 6, and then the coiled material is pushed away from the loading shaft 6 by the second pushing assembly 10. Compared with the prior art, the pushing structure has only one level of pushing structure, and when the coiled material is pushed to the end of the loading shaft 6, there is still a distance from the end of the loading shaft 6, so it is difficult to realize that the coiled material is completely separated from the loading shaft 6. The technical scheme in the application adopts the two-level pushing structure of the first pushing assembly 9 and the first pushing assembly 9, the coiled material is pushed to the end of the loading shaft 6 by the first pushing assembly 9, and then the coiled material is pushed away from the loading shaft 6 by the second pushing assembly 10, which is helpful to improve the condition that the existing pushing structure is difficult to realize that the coiled material is completely separated from the loading shaft 6.

[0068] The above are preferred embodiments of the application, and do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape, principle of the application should be covered in the protection scope of the application.
