Description

Technical Field

[0001] The present invention relates to the technical field of diaphragm conveying, and in particular to a conveying line and a use method thereof for facilitating material transportation. Background Art

[0002] In the structure of lithium batteries, the separator is one of the key internal components. The performance of the separator determines the battery's interface structure and internal resistance, directly affecting the battery's capacity, cycle life, and safety. A high-performance separator plays a vital role in improving the battery's overall performance.

[0003] At present, with the rapid development of the domestic new energy battery industry, the demand for lithium battery separators has further expanded. The packaging requirements for lithium battery separators before storage and transportation are higher, and efficient packaging operations with no damage and the same specifications are required. However, the existing manual method leads to low packaging efficiency, easy mixing of separators of different specifications, and easy contact and squeezing of the separators during long working hours (in order to reduce resistance, the electrode area must be as large as possible, so the separator must be very thin), causing the separator to be contaminated or damaged and not meet the standards (affecting the separator's separation effect on the positive and negative electrodes). In addition, there is also the possibility that the separator itself has defects such as contamination or damage. Manual workers do not have extra time to observe and inspect while taking into account the packaging, resulting in unqualified separators after the final packaging, causing customers to return them, wasting a lot of manpower and material resources.

[0004] During manual packaging, for the device that transports the roll film, the transport device needs to be removed manually after the roll film is removed, otherwise it will occupy the conveyor line path and cause the conveyor line to be blocked. Manually taking and placing the transport device requires adding workers to the conveyor line, wasting a lot of manpower. Therefore, simply using manual labor to carry out diaphragm packaging can no longer meet market demand. Summary of the Invention

[0033] The embodiment of the present invention further discloses a method for using a conveyor line for facilitating material transportation, comprising the following steps:

[0034] Transport: take out the film roll manually or automatically, and place the film roll on the conveying system from the left and right sides for transport;

[0035] Inspection, through the conveying system, the roll film is transported to the inspection system,

[0036] Turning, through the inspection system, the film roll is transported to the transfer system, so that the film roll moves in the longitudinal direction;

[0037] Transfer, through the transport system, the roll film is transported to the material taking system, the roll film on the loading device is taken out by the material taking system, and the roll film is placed in the next process;

[0038] Return material: After the roll film is taken off by the material taking system, the empty carrier is transported to the conversion system to make the carrier return.

[0039] Furthermore, in an embodiment of the present invention, in the transport step, after the roll film is inserted into the placement rods of the loading device from the left and right sides, the conveying motor in the conveying system is started to drive the conveying roller to rotate, thereby driving the loading device and the roll film thereon to move forward.

[0040] Furthermore, in an embodiment of the present invention, when the object carrier moves, the moving direction of the object carrier is limited by the upper retaining wall of the conveying system.

[0041] Furthermore, in an embodiment of the present invention, in the inspection step, when the roll film moves through the first conveyor belt on the first inspection rack, the inspection device automatically or manually inspects whether the roll film is intact and qualified.

[0042] Furthermore, in an embodiment of the present invention, the qualified roll film after inspection is moved to the guide system and then to the transfer system through the guide system; the unqualified roll film products after inspection are removed from the loading device by an external machine or manually, and the empty loading device is also moved to the guide system.

[0043] Furthermore, in an embodiment of the present invention, in the transfer step, the qualified roll film on the carrier is transported to the material picking system via the transfer system, and then the qualified roll film on the carrier is removed by an external machine and the qualified roll film is carried out to the next process; the empty carrier is moved to the conversion system through the second material picking rack of the material picking system.

[0044] Furthermore, in an embodiment of the present invention, in the reflow step, after the empty loading device is transported to the conversion system via the second material picking rack, the loading device stays on the driven rod, and the telescopic motor pushes the telescopic rod to move downward, and the telescopic rod pushes the movable plate downward, thereby driving the empty loading device on the movable plate to move downward.

[0045] Furthermore, in an embodiment of the present invention, after the movable plate moves downward, it stops moving after the movable plate and the reflow rack of the reflow system are aligned, and the driving rod is controlled to rotate by a connected external motor. The external motor drives the driving rod to rotate, thereby driving the active rod to control the rotation of the driven rod. When the driven rod rotates, the carrier device on the driven rod is moved out, and the carrier device moves toward the reflow rack. The empty carrier device is moved to the second inspection rack through the reflow rack, and the empty carrier device is moved to the second conveying rack through the second inspection rack to form a reflow.

[0046] The beneficial effects of the present invention are:

[0047] First, the loading device and its roll film are transported through the conveying system and the inspection system, and the roll film is automatically transported to the inspection system through the conveying system and the inspection system, so that the conveying system and the inspection system can interact with each other even if they are set separately to prevent multiple conveying systems from being on the same device, which may cause one device to be damaged and the other devices to be unable to operate, and realize the coexistence of multiple conveying systems. The roll film transported by the conveying system is inspected by the inspection system to see if there is any damage or substandard contamination on the roll film.

[0048] Second, the qualified roll film after inspection is transferred and transported through the diversion system, transfer system, and material taking system, and the unqualified roll film is removed from the loading device, which helps to prevent the material taking system from mixing unqualified and qualified products, resulting in unqualified products being mixed into subsequent processes.

[0049] Third, the carrier device that has taken away the roll film through the material taking device becomes empty. The position of the carrier device is changed through the conversion system so that the carrier device can be refluxed and collected through the reflux system, which is conducive to the reuse of the carrier device, reduces the need for manual collection and concentration of the carrier device, wastes manpower, and improves the degree of automation.

[0050] Based on the above three points, the material transportation conveying line includes the conveying system, inspection system, transfer system, material picking system, conversion system, reflux system, and diversion system, each of which is indispensable. The working process they constitute is closely linked, which can greatly improve the inspection and accuracy. If any system is missing, the technical effects produced will be greatly reduced, such as reducing the product failure rate and increasing the reuse rate of the carrier device, and higher automation cannot be achieved.

[0080] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.

[0081] Example 1:

[0082] like Figure 1 、 2 As shown, this embodiment discloses a conveyor line that facilitates material transportation, including: a conveying system 10, which is arranged along a first direction; an inspection system 20, which is arranged on one side of the conveying system 10; a conversion system 50, which is arranged on one side of the inspection system 20; a reflow system 60, which is arranged on one side of the conversion system 50; and a loading device 80, which is arranged above the conveyor line.

[0083] When the embodiment of the present invention transports the roll film 90, the roll film 90 is first taken out manually or automatically, and the roll film 90 is placed on the loading device 80 from the left and right sides. The loading device 80 is then transported by the conveying system 10 to the inspection system 20, so that the roll film 90 is arranged in the front-to-back direction. The roll film 90 is then sent to the guide system 70 after being inspected by the inspection system 20, and then sent to the transfer system 30 through the guide system 70. Then, the transfer system 30 sends the roll film 90 to the material picking system 40, and the roll film 90 on the loading device 80 is taken away by an external device. The loading device 80 is then moved to the second material picking rack 402 and then moved to the conversion system 50 via the second material picking rack 402. Finally, the empty loading device 80 is moved to the reflux system 60 through the conversion system 50, and the empty loading device 80 is recovered through the reflux system 60.

[0084] Specifically, the conveying line that facilitates material transportation also includes: a guide system 70, which is arranged on one side of the inspection system 20; a transfer system 30, which is arranged on one side of the guide system 70; and a material picking system 40, which is arranged on one side of the transfer system 30.

[0085] Specifically, the conveying system 10 includes: a first conveying frame 101; a conveying roller 102, which is movably connected to the first conveying frame 101; and a second conveying frame 103, which is arranged below the first conveying frame 101, with a distance between the second conveying frame 103 and the first conveying frame 101.

[0086] Specifically, the conveying system 10 further includes: a conveying motor, which is mounted on the first conveying frame 101 and connected to the conveying roller 102; the conveying motor is connected to the conveying roller 102 through a crawler belt or a chain or directly.

[0087] Specifically, the inspection system 20 includes: a first inspection rack 201; the first inspection rack 201 is arranged on the right side of the first conveyor rack 101; a first conveyor belt 203, the first conveyor belt 203 is movably connected to the first inspection rack 201; a second inspection rack 202, the second inspection rack 202 is arranged below the first inspection rack 201, and a distance is set between the second inspection rack 202 and the first inspection rack 201; a lighting device 204, the lighting device 204 is arranged above the first inspection rack 201, the lighting device 204 is fixedly connected to the first inspection rack 201, and a distance is set between the light source of the lighting device 204 and the first conveyor belt.

[0088] The conveying system 10 and the inspection system 20 are both double-layer conveying structures on the upper and lower sides. The upper layer is used to transport the carrier 80 and the roll film 90 thereon, and the lower layer is used to transport the carrier 80 back to the upper layer at the front end of the conveying system 10. Specifically, a conversion system 50 is set at the right side of the front end of the material picking system 40 and the rear end of the return system 60. Specifically, the telescopic motor 507, the telescopic rod 512, the moving plate 504 and the like are connected in a coordinated manner. The carrier 80 on the upper layer of the material picking system 40 is received through the moving plate 504, and then the moving plate 504 is lowered by the telescopic motor 507 to drive the carrier 80 to descend. After that, the driving rod 505 is rotated to rotate the driven rod 508 to push the carrier 80 to the upper layer of the return rack 601 of the return system 60, and then the return system 60 is returned to the upper layer of the return rack 601. The return rollers of the flow rack 601 move the carrier 80 to the front end of the second inspection rack 202 on the lower level of the inspection system 20. The second inspection rack 202 then moves the carrier 80 from the second inspection rack 202 on the lower level of the inspection system 20 to the second conveyor rack 103 on the conveyor system 10. Finally, an external elevator coordinated with the conveyor system 10 receives the carrier 80 from the second conveyor rack 103 on the lower level of the conveyor system 10 and transfers it to the first conveyor rack 101 on the upper level of the conveyor system 10. This double-layer process allows for rapid and orderly layering of the film roll 90, ensuring that the film roll 90 can be transported and recycled without interfering with the carrier 80, significantly improving work efficiency. Since the conveying system 10 and the inspection system 20 are mechanical mechanisms for transporting materials, in order to facilitate loading, maintenance and inspection, the height of the conveying system 10 and the inspection system 20 should usually correspond to the position between the hips and waist of the staff. The present application makes full use of the lower space of the conveying system 10 and the inspection system 20 to form an upper and lower double-layer transportation structure, which greatly reduces the floor space. This method is conducive to the arrangement of more conveying systems 10 and inspection systems 20 to enhance the efficiency of packaging operations.

[0092] Specifically, the guide system 70 further includes: a guide roller, which is movably connected to the first guide frame 701 and the second guide frame 702. The guide roller is controlled by a guide motor, and the guide motor is directly connected to the guide roller through a track or a chain.

[0098] Specifically, the loading device 80 is used to place the roll film 90 and then drive the roll film 90 to move along a specified path of the conveyor line.

[0099] Specifically, the loading device 80 is lower than the surface of the conveying system 10, the inspection system 20, the guide system 70, the transfer system 30, the material taking system 40, and the return system 60. The guide system 70, the transfer system 30, and the material taking system 40 are arranged to form a conveying route in a “]” shape.

[0100] Specifically, such as Figure 6 、 7 As shown, the loading device 80 includes: a second substrate 805; a first substrate 803, the first substrate 803 is arranged above the second substrate 805, and a gap is arranged between the first substrate 803 and the second substrate 805; a support column 801, the support column 801 is arranged on the upper surface of the first substrate 803, and the support column 801 is fixedly connected to the first substrate 803; a placing rod 802, the placing rod 802 is arranged on both sides of the supporting column 801, and the placing rod 802 is fixedly connected to the supporting column 801; a roller 804, the roller 804 is arranged between the first substrate 803 and the second substrate 805.

Four groups of rollers 804 are located on the four sides of the first substrate 803 and the second substrate 805. When the substrates move, if they come into contact with the frames of the various systems, the substrates will not collide with the frames, preventing the carrier 80 from moving. Instead, when the rollers 804 hit the frames during transport, the rollers can rotate to prevent the collision and continue to move without clogging the conveyor line. Furthermore, if the substrates hit the frames, the film rolls on the carrier will shake, potentially causing collisions between the film rolls, which in turn will lead to contact contamination of the film membranes, affecting membrane quality.

[0104] Specifically, an opening is provided on one side of the housing 501 corresponding to the second material taking rack 402 , and the area of ​​the opening is larger than the area of ​​the loading device 80 . The loading device 80 enters the housing 501 through the opening via the second conveyor belt 403 .

[0105] Specifically, a ball bearing 514 is provided inside the sliding sleeve 503 , and the ball bearing 514 is used for the sliding sleeve 503 to move up and down along the sliding rod 502 .

[0106] Specifically, two telescopic motors 507 are provided, and the telescopic motors 507 are fixedly connected by a horizontal plate. The telescopic motor 507 is vertically arranged inside the casing 501, and the two telescopic motors 507 are arranged opposite to each other; four sliding rods 502 are provided, and the sliding rods 502 are vertically arranged on the bottom surface of the casing 501. The telescopic motor 507 and the sliding rods 502 are in the same plane, and the sliding rods 502 are divided into a group of two, and every two sliding rods 502 are connected by a horizontal rod, and the telescopic motor 507 is provided on the upper surface of the horizontal rod of the sliding rod 502.

[0107] Specifically, the conversion system 50 also includes: a mounting plate 510, the mounting plate 510 is arranged on the upper surface of the movable plate 504, and the mounting plate 510 is fixedly connected to the movable plate 504; a driving rod 505, the driving rod 505 is arranged on one side of the mounting plate 510, and the driving rod 505 is connected to the mounting plate 510; an active rod 506, the active rod 506 is arranged on one side of the mounting plate 510, and the active rod 506 is connected to the driving rod 505; a driven rod 508, the driven rod 508 is arranged on one side of the mounting plate 510, and the driven rod 508 is connected to the mounting plate 510; a guide plate 509, the guide plate 509 is arranged on the inner side of the mounting plate 510, and the guide plate 509 is connected to the mounting plate 510.

[0108] Specifically, two mounting plates 510 are provided, and a distance is provided between the two mounting plates 510 , and the distance is used to place the driven rod 508 , the active rod 506 , and the object carrying device 80 .

[0109] Specifically, the opposite ends of the driven rod 508 are movably connected to the two mounting plates 510 respectively, the driven rod 508 is engaged with the active rod 506, and the driving rod 505 is connected to an external motor, which drives the driving rod 505 to rotate and drives the active rod 506 to rotate; the first substrate 803 and the second substrate 805 are connected by snaps, and the snaps are located at the four corners of the first substrate 803 and the four corners of the second substrate 805.

[0110] The guide plate 404 is fixedly connected to the second material picking rack 402, and the guide plate 404 is inserted into the housing 501 of the conversion system 50. When the conversion system 50 has not yet converted the conveying trajectory of the carrier 80, the carrier 80 is conveyed to the conversion system through the second material picking rack 402. When the carrier 80 enters the interior of the conversion system 50, the second material picking rack 402 cannot be connected with the conversion system 50 in a coordinated manner, because the use of a coordinated connection will increase the difficulty of equipment installation. At the same time, the use of a coordinated connection will cause the conversion system 50 and the second material picking rack 402 to require cumbersome operating steps when disassembling. The guide plate 402 is used to guide the carrier 80 when it moves toward the conversion system 50, so that the carrier 80 will not be positionally offset when entering the interior of the conversion system 50, causing the roll film on the carrier 80 to collide. In addition, the guide plate 404 is on the moving plate 50 of the conversion system 50. When the carrier 80 is not lowered, the guide plate 404 cooperates with the guide plate 509 provided above the movable plate 504. The guide plate 404 is provided on the inner side of the guide plate 509. When the movable plate 504 moves the carrier 80 downward, the guide plate 404 and the guide plate 509 are separated, so that a gap is left between the carrier 80 and the guide plate 509, and the second base plate 805 of the carrier 80 is in contact with the driven rod 508. Since the driven rod 508 is controlled by the active rod 506, when the active rod 506 is not rotating, the driven rod 508 is in contact with the active rod 506. The movable rod 508 will not rotate, which ensures that the loading device 80 in close contact with the driven rod 508 will not shake during transportation, resulting in position deviation and affecting the delivery accuracy. In addition, the ball 514 arranged inside the sliding sleeve cooperates with the sliding rod 502, which can also make the movable plate 504 generate less friction with the sliding rod 502 during the lifting process, thereby reducing the vibration of the loading device 80 on the driven rod 508 and avoiding the position deviation of the loading device 80 during transportation.

[0111] like Figure 9 As shown, a conveyor line for facilitating material transportation is finally provided, comprising the following steps:

[0112] Transporting: taking out the film roll 90 manually or automatically, and placing the film roll 90 from the left and right sides onto the conveying system 10 for transport;

[0113] Inspection, through the transport system 10, the roll film 90 is transported to the inspection system 20,

[0114] Turning, through the transportation of the inspection system 20, the film roll 90 is transported to the transfer system 30, so that the film roll 90 moves in the longitudinal direction;

[0115] Transferring: The film roll 90 is transported to the material taking system 40 via the transport system 30 . The film roll 90 on the loading device 80 is taken out by the material taking system 40 and placed into the next process.

[0116] After the roll film 90 is taken down by the material taking system 40 , the empty carrier 80 is transported to the conversion system 50 , so that the carrier 80 is returned.

[0117] Specifically, in the transport step, after the roll film 90 is inserted into the placement rod 802 of the loading device 80 from the left and right sides, the conveying motor in the conveying system 10 is started to drive the conveying roller 102 to rotate, thereby driving the loading device 80 and the roll film 90 thereon to move forward.

[0118] Specifically, when the object carrier 80 moves, the moving direction of the object carrier 80 is limited by the upper retaining wall of the conveying system 10 .

[0119] Specifically, in the inspection step, when the roll film 90 moves through the first conveyor belt 203 on the first inspection rack 201, the roll film 90 is inspected automatically or manually by an inspection device to determine whether it is intact and qualified.

[0120] Specifically, the qualified roll film 90 after inspection is moved to the guide system 70 and then to the transfer system 30 through the guide system 70; the unqualified roll film 90 products after inspection are removed from the loading device 80 by an external machine or manually, and the empty loading device 80 is also moved to the guide system 70.

[0121] Specifically, in the transfer step, the qualified roll film 90 on the carrier device 80 is transported to the material picking system 40 via the transfer system 30, and then the qualified roll film 90 on the carrier device 80 is removed by an external machine, and the qualified roll film 90 is carried out to the next process; the empty carrier device 80 is moved to the conversion system 50 through the second material picking rack 402 of the material picking system 40.

[0122] Specifically, in the reflow step, after the empty loading device 80 is transported to the conversion system 50 via the second material picking rack 402, the loading device 80 stays on the driven rod 508, and the telescopic motor 507 pushes the telescopic rod 512 to move downward. The telescopic rod 512 pushes the movable plate 504 to move downward, thereby driving the empty loading device 80 on the movable plate 504 to move downward.

[0123] Specifically, after the movable plate 504 moves downward, it stops moving after the movable plate 504 is aligned with the reflow rack 601 of the reflow system 60, and the driving rod 505 is controlled to rotate by the connected external motor. The external motor drives the driving rod 505 to rotate, thereby driving the active rod 506 to control the rotation of the driven rod 508. When the driven rod 508 rotates, the carrier 80 on the driven rod 508 is moved out, and the carrier 80 is moved toward the reflow rack 601. The empty carrier 80 is moved to the second inspection rack 202 through the reflow rack 601, and the empty carrier 80 is moved to the second conveying rack 103 through the second inspection rack 202 to form a reflow.

[0124] The loading device 80 and its roll film 90 are transported by the conveying system 10 and the inspection system 20, and the roll film 90 is automatically transported to the inspection system 20 through the conveying system 10 and the inspection system 20, so that the conveying system 10 and the inspection system 20 can interact with each other even if they are separately arranged to prevent multiple conveying systems from being on the same device, which may cause one device to be damaged and the other devices to be unable to operate, and realize the coexistence of multiple conveying systems. The roll film 90 transported by the conveying system 10 is inspected by the inspection system 20 to see whether the roll film 90 is damaged or contaminated.

[0125] The qualified roll film 90 after inspection is transferred and transported through the guide system 70, the transfer system 30, and the material taking system 40, and the unqualified roll film 90 is removed from the loading device 80, which helps to prevent the material taking system 40 from mixing unqualified and qualified products, resulting in unqualified products being mixed into subsequent processes.

[0126] The carrier device 80 after the roll film 90 is taken away by the material taking device becomes empty. The position of the carrier device 80 is changed by the conversion system 50 so that the carrier device 80 can be refluxed and collected by the reflux system 60, which is conducive to the reuse of the carrier device 80, reduces the need for manual collection and concentration of the carrier device 80, wastes manpower, and improves the degree of automation.

[0127] Based on the above content, the material transportation conveyor line includes a conveying system 10, an inspection system 20, a transfer system 30, a material picking system 40, a conversion system 50, a reflux system 60, and a diversion system 70, none of which can be dispensable. The working processes they constitute are closely linked, which can greatly improve the inspection and accuracy. If any one system is missing, the technical effects produced will be greatly reduced, such as reducing the product failure rate and increasing the reuse rate of the carrier 80, and higher automation cannot be achieved.
