Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery structural parts loading and unloading conveying systems, and more specifically, to a lithium battery production and handling system and a control method thereof. Background Art

[0002] Lithium battery structural parts refer to the various components and parts that make up lithium batteries, including shells, covers, positive and negative electrodes, diaphragms, electrolytes, etc. These structural parts play a key role in lithium batteries, such as transmitting energy, carrying electrolytes, protecting battery safety, and fixing and supporting batteries.

[0003] Different types of lithium batteries often have different structural parts. When producing lithium batteries on existing production lines, the loading of structural parts is usually done manually, which requires a lot of manpower and is not conducive to the humidity environment control of the workshop. In addition, for workshops that produce multiple types of lithium battery production lines at the same time, it is necessary to manually distinguish the material types for loading, which is prone to errors and rework. Although AGV transportation has now been used to replace manual labor, walking channels need to be reserved next to the line when planning AGV transportation, and in workshops with a large flow of people on production equipment, it is necessary to constantly avoid obstacles with humans during walking, and the operating efficiency is low.

[0047] Specifically combined Figure 1 As shown, a lithium battery production and transportation system includes a production conveying system 100, an overhead crane conveying system 4 and a material preparation conveying system 5.

[0048] The production conveying system 100 is arranged in the production area, including at least one production line, each production line is provided with two or more production equipment, and the production equipment includes a material unloading conveyor and a material loading conveyor. One end of the material unloading conveyor is provided with a production pallet recovery position 45 corresponding to one end of the material loading conveyor, and one end of the material loading conveyor is provided with a production loading position 44 corresponding to one end.

[0049] The overhead crane conveying system 4 is located above the production conveying system 100, and includes at least one track 41 connected end to end. A plurality of trolley assemblies 43 are arranged on the track 41. The trolley assemblies 43 circulate along the track 41 to convey pallets; the trolley assemblies 43 can convey pallets loaded with materials to the production loading position 44, and transfer the pallets loaded with materials to the loading conveyor; the trolley assemblies 43 can convey to the production pallet recovery position 45 for recovering empty pallets returned from the unloading conveyor.

[0050] The material preparation and conveying system 5 is arranged in the material preparation area, including multiple material preparation conveying lines 51, and one end of the material preparation conveying line 51 extends into the production area; at least one material preparation conveying line 51 is located in the production area at one end and a material preparation pallet recovery position 46 is correspondingly set, and at least another material preparation conveying line 51 is located in the production area at one end and a material preparation unloading position 47 is correspondingly set; the trolley assembly 43 can be transported to the material preparation pallet recovery position 46 to transfer the returned empty pallet to the corresponding material preparation conveying line 51, and the trolley assembly 43 can be transported to the material preparation unloading position 47 to transfer the pallet loaded with materials on the corresponding material preparation conveying line 51.

[0051] Furthermore, the unloading conveyor includes a plurality of rollers arranged in parallel, and the rotation direction of the rollers is arranged toward the production tray recovery position 45; the loading conveyor includes a plurality of rollers arranged in parallel, and the rotation direction of the rollers is arranged away from the production loading position 44. The rotation of the rollers can be driven by a motor and a belt, and the roller driving method is a common prior art and will not be described here.

[0052] Specifically, the three production lines are the first production line 1, the second production line 2 and the third production line 3, and the equipment layout on each production line is consistent. It should be noted that in other schemes, the number of production lines can also be set to other, but at least one production line must be included. Taking the first production line 1 as an example for detailed description, the production equipment includes the first production equipment 10 and the second production equipment 11, the first production equipment 10 includes the first unloading conveyor 101 and the first loading conveyor 102, and the second production equipment 11 includes the second unloading conveyor 111 and the second loading conveyor 112. Specifically, the production of two types of lithium batteries is described, including the corresponding materials X and material Y need to be loaded, wherein the first production equipment 10 is used for loading and unloading of material X, and the second loading conveyor 112 is used for loading and unloading of material Y. The structures of the first production equipment 10 and the second production equipment 11 are consistent, and the materials conveyed are different. Specifically, the first production equipment 10 is used as an example for description. One end of the first loading conveyor 102 in the first production equipment 10 corresponding to the production loading position 44 is the loading port, and the other end is the unloading port. One end of the first unloading conveyor 101 corresponding to the production pallet recovery position 45 is a unloading port, and the other end is a loading port. The pallet is conveyed on the trolley assembly 43. The required materials are loaded on the pallet during feeding, and the empty pallet is recovered during collection. At the loading port of the first loading conveyor 102, the trolley assembly 43 transports the pallet loaded with materials to the production loading position 44, and the pallet is transported to the first loading conveyor 102 through the loading port. The first loading conveyor 102 transports the material X to the battery processing equipment. After the material is taken, the empty pallet is transferred to the loading port of the first unloading conveyor 101, and then transported to the unloading port of the first unloading conveyor 101, and then transferred to the trolley assembly 43 located at the production pallet recovery position 45.

[0053] It should be noted that although the first production equipment 10 and the second production equipment 11 for conveying have the same structure, they convey different materials. Due to the difference in materials, the battery processing equipment will be different, and the battery processing equipment on other production lines will be adjusted accordingly according to the battery model.

[0054] The loading and unloading of material Y on the second loading conveyor 112 is consistent with the loading and unloading of material X on the first production equipment 10. Although the types of materials conveyed by the trolley assembly 43 are different, in order to ensure the universality of the trolley assembly, the structure of each trolley assembly is consistent and the specifications and sizes of the pallets are consistent.

[0055] Recombination Figure 1 As shown, the material preparation conveying line 51 in the material preparation conveying system 5 includes a plurality of rollers arranged in parallel, wherein the rotation direction of the rollers on the material preparation conveying line 51 corresponding to the material preparation pallet recovery position 46 is away from the material preparation pallet recovery position 46, and the rotation direction of the rollers on the material preparation conveying line 51 corresponding to the material preparation unloading position 47 is toward the material preparation unloading position 47.

[0056] For ease of explanation, the multiple material preparation conveying lines 51 in the material preparation conveying system 5 are respectively material preparation conveying line 51-a, material preparation conveying line 51-b, material preparation conveying line 51-c and material preparation conveying line 51-d, wherein the material preparation conveying line 51-a is arranged corresponding to the material preparation pallet recovery position 46, and the material preparation conveying line 51-b, material preparation conveying line 51-c and material preparation conveying line 51-d are arranged corresponding to the material preparation unloading position 47. In other cases, the material preparation conveying lines 51 can also be set to other numbers.

[0057] As a further improvement, a transplanter 53 is provided at one end of the material preparation conveyor line 51 in the material preparation area, and the transplanter 53 is used to turn the pallet. The upper part of the transplanter 53 includes a belt conveyor structure, which includes a plurality of belts arranged at intervals. The belt conveying direction is different from that of the material preparation conveyor line 51, and the belt and the roller are arranged at intervals. The belt can be driven by a motor. In addition, the belt conveyor structure can be raised and lowered at the same time, and the raising and lowering of the belt conveyor structure can be controlled by existing common structures such as gear racks.

[0058] Adjacent transplanters 53 are connected to a transfer conveyor line 57, which includes a plurality of rollers arranged in parallel, and the rotation direction of the rollers is consistent with the conveying direction of the transplanter 53. Specifically, the conveying direction of the belt on the transplanter 53 is consistent with the direction of the transfer conveyor line 57. Figure 1 Taking the middle view direction as an example, in this embodiment, the material preparation conveyor line 51-a, the material preparation conveyor line 51-b, the material preparation conveyor line 51-c and the material preparation conveyor line 51-d are all arranged vertically, and the transfer conveyor line 57 is arranged horizontally.

[0059] As a preferred embodiment, one end of the material preparation conveying line 51 extending into the production area is a docking port 58 for connecting with the trolley assembly 43 in the overhead crane conveying system 4, and an isolation door 52 that can be opened and closed is arranged above the material preparation conveying line 51 near the docking port 58. Furthermore, the isolation door 52 includes a first isolation door and a second isolation door, and the first isolation door and the second isolation door are arranged at intervals, wherein the first isolation door is arranged near the production area, and the second isolation door is arranged near the material preparation area.

[0060] More specifically, a transplanter 53 is provided at one end of the material preparation conveyor line 51-a, and a code scanning component 55 is provided on one side of the transplanter 53. The code scanning component 55 can be an existing code scanning gun, etc. A transplanter 53 is provided at one end of the material preparation conveyor line 51-b, the material preparation conveyor line 51-c and the material preparation conveyor line 51-d, and a material preparation loading port 54 is provided on one side of the transplanter 53. A roller-type conveyor line is also provided at the material preparation loading port 54. A start button 56 is provided next to the roller-type conveyor line, and materials are manually loaded at the material preparation loading port 54.

[0061] Similarly, the material X feeding system is used as an example for explanation, wherein the material preparation conveyor line 51-a is used for the return of empty pallets, and the material preparation conveyor lines 51-b, 51-c and 51-d are used for the conveyance of full pallets. In some cases, the material preparation conveyor lines 51-b, 51-c and 51-d can correspond to the feeding requirements of the first production line 1, the second production line 2 and the third production line 3. The trolley assembly 43 conveys the empty pallet to the material preparation pallet recovery position 46, and the empty pallet enters the material preparation conveyor line 51-a through the docking port 58. When the empty pallet is conveyed to the isolation door 52, the first isolation door opens, and the empty pallet is conveyed between the first isolation door and the second isolation door, and the first isolation door closes. After the first isolation door is closed, the second isolation door opens, and the empty pallet continues to be conveyed. After that, the second isolation door closes, and the empty pallet continues to be conveyed to the transplanter 53. The belt on the transplanter 53 rises to support the pallet, thereby conveying the pallet to the transfer conveyor line 57.

[0062] Taking the loading of the material preparation conveyor line 51-b as an example, after manual loading at the material preparation loading port 54, the full pallet enters the material preparation conveyor line 51-b, and continues to be transported to the isolation door 52, the second isolation door opens, the full pallet is transported to between the first isolation door and the second isolation door, and the second isolation door closes. After the second isolation door is closed, the first isolation door opens, the full pallet continues to be transported, and then the first isolation door closes, and the full pallet continues to be transported to the docking port 58, and then the full pallet is transferred to the trolley assembly 43 located at the material preparation unloading position 47.

[0063] The setting and conveying method of the material preparation and conveying system 5 for material Y are the same as those for material X.

[0064] In addition, the isolation door 52 includes a first isolation door and a second isolation door. The production area and the material preparation area have different environmental requirements. The setting of the double isolation door can effectively reduce the environmental exchange between the production area and the material preparation area.

[0065] As a preferred embodiment, when multiple end-to-end tracks 41 are provided, different tracks 41 have a common track portion and a non-common track portion, and the non-common track portion is arranged above each production line. Moreover, the common track portion and the non-common track portion are switched by a track switching assembly 42.

[0066] In this embodiment, a first production line 1, a second production line 2 and a third production line 3 are provided, and three non-shared track sections are provided, which are respectively located above the first production line 1, the second production line 2 and the third production line 3 to transport materials therefor. Figure 1As shown, the circulating track 41 for conveying materials for the first production line 1 includes a common track portion 1a and a non-common track portion 1b, and the non-common track portion 1b is arranged above the first production line 1; the circulating track 41 for conveying materials for the second production line 2 includes a common track portion 2a and a non-common track portion 2b, and the non-common track portion 2b is arranged above the second production line 2, wherein the common track portion 1a shares a portion of the track of the circulating track 41 for conveying materials for the second production line 2; the circulating track 41 for conveying materials for the third production line 3 includes a common track portion 3a and a non-common track portion 3b, and the non-common track portion 3b is arranged above the third production line 3, wherein the common track portion 2a shares a portion of the track of the circulating track 41 for conveying materials for the third production line 3.

[0067] Combination Figure 3 As shown, the trolley assembly 43 includes a trolley drive module 431, a trolley belt 432 and a support frame 433. A travel motor is provided in the trolley drive module 431, and the travel motor drives the roller to roll. When the roller rolls, it moves along the track 41 so that the trolley assembly 43 is transported. A plurality of rollers arranged side by side are provided on the support frame 433, and when the rollers rotate, they drive the tray to be loaded and unloaded. One end of the trolley belt 432 is connected to the trolley drive module 431, and the other end is connected to the support frame 433. In some cases, the trolley belt 432 can drive the support frame 433 to rise and fall. At this time, a lifting motor that drives the operation of the trolley belt 432 needs to be provided to control the lifting and falling of the support frame 433.

[0068] Combination Figure 4 and Figure 5 As shown, the track change assembly 42 includes a support plate and a first track 421 and a second track 422 located on the support plate. In one embodiment, the support plate moves back and forth between the first position and the second position under the action of the cylinder. When the support plate moves to the first position, as shown in FIG. Figure 4 As shown in, for example, the common track portion 1a is connected to the non-common track portion 1b through the second track 422; when the support plate moves to the second position, as shown in Figure 5 As shown in FIG. 4 , the common rail portion 1 a is connected to the common rail portion 2 a via the first rail 421 .

[0069] The overhead crane conveying system 4 also includes a maintenance position 40, which is located outside the circularly arranged track 41, and the track in the maintenance position 40 is also connected to the track 41 through a track change assembly 42. The maintenance position 40 is used to locate a trolley assembly 43 that has a fault.

[0070] The rotation of all the rollers in this solution can be driven by common existing methods such as motors and belts.

[0071] In this solution, there is at least one production line in the production area, and each production line is equipped with more than two production equipments for loading and unloading different materials. At the same time, multiple material preparation conveyor lines 51 are arranged in the material preparation area for loading and unloading different materials. The production area and the material preparation area are transferred through the trolley assembly 43 in the overhead crane conveying system 4, so as to realize the transportation of different structural materials when producing multiple lithium battery models in the same workshop, and the space utilization is reduced compared with the AGV conveying method.

[0072] like Figure 2 As shown, the present invention also provides a control method for a lithium battery production and handling system, which is used to control the lithium battery production and handling system.

[0073] Furthermore, the lithium battery production and handling system also includes a host computer 61, a scheduling system 62 and a conveying control system 63; the production equipment in the production conveying system 100 outputs a material demand, the host computer 61 interacts with the scheduling system 62 according to the material demand of the production equipment in the production conveying system 100, the scheduling system 62 interacts with the conveying control system 63, and the scheduling system 62 schedules the trolley assembly 43 in the overhead crane conveying system 4 to the material demand location according to the material demand, and at the same time the conveying control system 63 controls the movement of the corresponding trolley assembly 43 and the operation of the pallet.

[0074] Specifically, combined Figure 6 As shown, after a certain production equipment consumes a pallet of materials, it outputs a material demand, and the host computer 61 interacts with the scheduling system 62. The scheduling system 62 determines the material address and dispatches the corresponding trolley component 43 to load and unload materials. After the production equipment consumes a pallet of materials, it outputs a material demand and an empty pallet demand. The scheduling system 62 also determines the empty pallet address and dispatches the corresponding trolley component 43 to the corresponding position.

[0075] Combination Figure 7As shown, when the scheduling system 62 schedules the trolley assembly 43 according to the material calling address, in order to improve the operating efficiency, it is preferred to first determine whether the unloading conveyor and the loading conveyor of the same production equipment can simultaneously meet the empty and full tray exchange. For example, whether the loading and unloading ports of the first unloading conveyor 101 and the first loading conveyor 102 in the first production equipment 10 both have material calling requirements, that is, whether there are empty tray unloading and full tray loading task requirements. If so, according to the order of demand, the trolley is dispatched to the material preparation unloading position 47 corresponding to the material preparation conveyor line 51 to take away the full pallet, and then the conveying control system 63 releases the full pallet position, and the next full pallet runs to this position. After the trolley takes the full pallet, it runs to the production loading position 44 to complete the loading of the full pallet. After that, the trolley runs to the production pallet recovery position 45 of the material calling equipment, takes away the empty pallet from the unloading port there, and then runs to the preparation pallet recovery position 46 to return the empty pallet to the preparation conveyor line. Each time a loading or unloading action is completed, the scheduling system needs to interact with the system in the host computer to realize the closed loop of the task. If not, the scheduling system sets a certain waiting time T. If the loading and unloading ports of the same production equipment meet the empty and full exchange conditions within the waiting time T, the above process is executed. If not, the separate material calling operation of the material calling port is executed. The conveying control system 63 can be implemented by PLC.

[0076] like Figure 8 As shown, before the trolley runs to the position where the track change assembly is required, the track assembly receives the track change request, executes the track change assembly action, completes the track change, and the trolley assembly continues to move along the specified track.

[0077] like Fig. 9 As shown, the conveying control system 63 interacts with the scheduling system. After receiving the empty pallet return task, the conveying control system 63 controls the material preparation conveyor line 51-a to convey the empty pallet forward. The empty pallet is transferred to the transplanter 53, and the code scanning component 55 performs a code scanning judgment to determine the material type of the pallet. After the judgment is completed, it moves forward along the transfer conveyor line 57 and moves to the corresponding manual material preparation loading port 54. After the manual loading is completed, the start button 56 is pressed, and the full pallet is transferred to the corresponding model of the material preparation conveyor line 51-b, the material preparation conveyor line 51-c or the material preparation conveyor line 51-d, and then enters the docking port 58 to perform the next step of the loading task with the trolley component.

[0078] In this solution, there is at least one production line in the production area, and each production line is equipped with more than two production equipments for loading and unloading different materials. At the same time, multiple material preparation conveyor lines 51 are set up in the material preparation area for loading and unloading different materials.
