Description

Technical Field

[0001] The present application relates to the technical field of battery cell production, and in particular to battery cell circulation equipment. Background Art

[0002] During the production of solar cells, the cells need to be processed. However, the same processing equipment can only process a limited number of cells at a time. Therefore, it is necessary to take out the cells that have completed the processing in the processing equipment, and then put the cells to be processed into the processing equipment. Usually, this process needs to be repeated many times to complete the processing of all cells.

[0003] At present, solar cell manufacturers use cell transfer equipment to complete the above process. Specifically, first, multiple boats carrying cells to be processed are placed in the same boat container, and the outer side of the boat container is usually provided with a hanging ear. Then, the cell transfer equipment is used to hold the hanging ear of the boat container to hold the boat container into the process treatment equipment. After the cell transfer equipment places the boat container in the process treatment equipment, the cell transfer equipment leaves the process treatment equipment. When the process treatment equipment completes the process treatment, the cell transfer equipment enters the process treatment equipment again to hold the hanging ear of the boat container to hold the boat container out of the process treatment equipment. After that, the boat in the boat container is taken out, and after the large boat is cooled, multiple boats carrying cells to be processed are placed in the boat container to cycle the above process until all cells have completed the process treatment. However, this causes the process treatment equipment to wait for the boat container to cool down, which will increase the heat loss of the process treatment equipment and reduce the production efficiency of the cells. Utility Model Content

[0004] Based on this, it is necessary to provide a battery cell circulation equipment to address the above problems, which can reduce the heat loss of process equipment and improve the production efficiency of battery cells.

[0005] In order to solve the above problems, the present application provides the following technical solutions:

[0006] A battery cell circulation device comprises a frame and an upper cache assembly, a middle transport assembly, and a lower cache assembly which are arranged in sequence from top to bottom, wherein the middle transport assembly can be raised and lowered and can be moved horizontally on the frame, the upper cache assembly, the middle transport assembly, and the lower cache assembly all comprise container supporting structures, each of the container supporting structures comprises two supporting members which are arranged at intervals, and the two supporting members of each container supporting structure on the upper cache assembly and the middle transport assembly can approach or move away from each other.

[0007] The battery sheet circulation equipment has at least the following beneficial effects:

[0008] Before one set of boat containers with battery cells completes processing in the process equipment, another set of boat containers remaining in the equipment body has completed cooling and loaded with boats carrying battery cells to be processed. After each process of the process equipment completes the process, the middle-level handling component immediately takes out one set of boat containers in the process equipment, and places the other set of boat containers remaining in the equipment body into the process equipment in a short time. Therefore, the process equipment does not need to wait for the boat containers to cool down, which can reduce the heat loss of the process equipment and improve the production efficiency of the battery cells.

[0009] In one of the embodiments, a supporting groove is provided on the supporting member, and the supporting groove is used to accommodate the hanging ear of the boat container.

[0010] Such arrangement enables the hanging ear of the boat-carrying container to be located between two opposite side walls of the supporting groove. The two opposite side walls of the limiting groove will limit the displacement of the hanging ear, which is conducive to the stable transfer of the boat-carrying container.

[0011] In one of the embodiments, each of the container supporting structures further comprises a first crossbeam connected to the frame, and in the same container supporting structure, both of the two supporting members are slidably connected to the first crossbeam.

[0012] With such arrangement, the two supporting members can be brought closer to each other by sliding toward each other, and can be moved away from each other by sliding away from each other.

[0013] In one of the embodiments, each of the container supporting structures further comprises a second beam connected to the frame, wherein the second beam is parallel to the first beam; in the same container supporting structure, both of the supporting members are slidably connected to the second beam.

[0014] With such arrangement, the first cross beam and the second cross beam jointly define the sliding direction of the supporting member, which is beneficial to improving the sliding accuracy and stability of the supporting member.

[0015] In one of the embodiments, each of the container supporting structures further comprises two groups of relatively arranged power output assemblies, each of the power output assemblies being fixedly connected to the first cross beam; each of the power output assemblies comprises a seat body and a power output member, the power output member being slidably / telescopically connected to the seat body along the length direction of the first cross beam; in the same container supporting structure, the two supporting members are respectively fixedly mounted on the power output members of the two power output assemblies.

[0016] With such arrangement, the supporting member can be driven to slide by the power output member.

[0017] In one embodiment, the battery cell transfer equipment also includes a lifting assembly and a transverse movement assembly, the lifting assembly includes a lifting seat body and a lifting member, and the lifting member is connected to the lifting seat body by sliding along the plumb direction; the transverse movement assembly includes a transverse movement seat body and a transverse movement member, and the transverse movement member is connected to the transverse movement seat body by sliding along the horizontal direction, and the middle-level transport assembly is fixed to the transverse movement member.

[0018] With such arrangement, the lifting and horizontal movement of the middle-layer transport component can be realized through the lifting component and the transverse movement component.

[0019] In one embodiment, a plurality of the container supporting structures are provided on the upper cache assembly, the middle transport assembly and the lower cache assembly.

[0020] With such an arrangement, the upper cache assembly, the middle transport assembly and the lower cache assembly can all overlap multiple boat containers and can transfer multiple boat containers at the same time. The middle transport assembly can place multiple boat containers on process equipment at the same time, which is beneficial to improving the production efficiency of battery cells.

[0021] In one of the embodiments, a plurality of the container supporting structures on the upper cache assembly / the middle transport assembly / the lower cache assembly are arranged side by side.

[0022] Such a configuration is conducive to fully utilizing the space of the upper cache component / middle-level transport component / lower-level cache component, and is conducive to reducing the size of the upper cache component / middle-level transport component / lower-level cache component.

[0023] In one of the embodiments, the battery cell circulation equipment also includes a boat cache vertical warehouse, which is arranged side by side with the rack. A plurality of boat supporting structures are provided on the boat cache vertical warehouse, and each of the boat supporting structures is used to place a boat.

[0024] With this arrangement, the boats that need to wait can be stored in the boat cache library, so that the boats that need to wait can be temporarily stored without interrupting the entire production process, so as to balance the production speed of each node on the photovoltaic module production line, prevent excessive congestion or stagnation of the photovoltaic module production line, and ensure an efficient process.

[0025] In one embodiment, the battery cell circulation equipment also includes a fork assembly arranged opposite to the boat cache warehouse, the fork assembly includes a fork seat body and a fork, the fork is arranged on the fork seat body so as to be liftable and movable in a horizontal plane so as to enter and exit any one of the boat supporting structures, and each of the boat supporting structures is provided with a fork avoidance space for the fork to pass up and down.

[0026] With such arrangement, the boat can be placed on any boat supporting structure by means of a cargo fork, or the boat on any boat supporting structure can be taken out by means of a cargo fork. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] See also Figures 1 to 5 The present application provides a battery cell circulation device, which can place a boat container 2 into / out of a process treatment device. The battery cell circulation device includes a device body 1, and the device body 1 includes a frame 15 and an upper cache component 11, a middle-layer transport component 12, and a lower cache component 13 arranged in sequence from top to bottom. The middle-layer transport component 12 is arranged on the frame 15 so as to be liftable and horizontally movable. The upper cache component 11, the middle-layer transport component 12, and the lower cache component 13 all include a container supporting structure 14, and each container supporting structure 14 includes two supporting members 141 arranged at intervals, and the two supporting members 141 of each container supporting structure 14 on the upper cache component 11 and the middle-layer transport component 12 can approach or move away from each other. The two supporting members 141 on each container supporting structure 14 on the lower cache component 13 can be fixed or can approach or move away from each other.

[0048] See also Figure 4 and Figure 5 The boat 5 is used to carry multiple battery cells, and the boat container 2 is used to carry multiple boats 5. The boat container 2 includes a container body 21 and a hanging ear 22 provided on the container body 21. The boat container 2 is provided with multiple container supporting structures 14 on any two adjacent ones of the upper cache component 11, the middle transport component 12 and the lower cache component 13, which can simultaneously hold different hanging ears on the same boat container 2 to realize the boat container 2, so that the boat container 2 can flow between the upper cache component 11 and the middle transport component 12, and between the middle transport component 12 and the lower cache component 13. The flow process of the boat container 2 will be described in detail below.

[0049] When using the battery cell circulation equipment, all the boat containers 2 are divided into two groups, which are the first group and the second group. When the first group of boat containers 2 are carrying the boat 5 carrying the battery cells to be processed in the process treatment equipment, the second group of boat containers 2 are all overlapped on the upper cache assembly 11 for cooling. During the cooling process of the second group of boat containers 2, the automated equipment or workers move the boat 5 carrying the battery cells that have been processed out of the second group of boat containers 2; after the second group of boat containers 2 are completely cooled, the automated equipment or workers load the boat 5 carrying the battery cells to be processed into the second group of boat containers 2. After the process treatment equipment completes the process treatment, the middle-level transport assembly 12 first moves horizontally until its container support structure 14 is located directly below the hanging ear 22 of the first group of boat containers 2, then rises to lift the first group of boat containers 2, and then moves horizontally to directly above the lower cache assembly 13, and then descends until the hanging ear 22 of the first group of boat containers 2 overlaps the container support structure 14 of the lower cache assembly 13. Afterwards, the two supporting members 141 on the middle-level transport assembly 12 move away from each other to release the state in which they support the first group of boat containers 2. Afterwards, the middle-level transport assembly 12 rises to the vicinity of the upper-level cache assembly 11. Afterwards, the two supporting members 141 on the middle-level transport assembly 12 move closer to each other to support the second group of boat containers 2. Afterwards, the two supporting members 141 on the upper-level cache assembly 11 move away from each other to release the state in which they support the second group of boat containers 2. Afterwards, the middle-level transport assembly 12 descends to a height position that allows the second group of boat containers 2 to enter the process treatment equipment horizontally while holding the second group of boat containers 2. Afterwards, the middle-level transport assembly 12 moves horizontally to enter the process treatment equipment. Afterwards, the middle-level transport assembly 12 descends to place the second group of boat containers 2 in the process treatment equipment. Afterwards, the middle-level transport assembly 12 moves horizontally and leaves the process treatment equipment to allow the process treatment equipment to perform process treatment. In this way, the following state is achieved: when the second group of boat containers 2 are carrying the boat 5 carrying the battery cells to be processed in the process treatment equipment, the first group of boat containers 2 are all overlapped on the lower cache component 13 for cooling. During the cooling process of the first group of boat containers 2, the automated equipment or workers will move the boat 5 carrying the battery cells that have been processed out of the first group of boat containers 2; after the first group of boat containers 2 have completed cooling, the automated equipment or workers will load the boat 5 carrying the battery cells to be processed into the first group of boat containers 2. After the process treatment equipment has completed the process treatment, a process similar to the above is used to remove the second group of boat containers 2 from the process treatment equipment and transfer it to the upper cache component 11 for cooling, and then the first group of boat containers 2 is transferred to the process treatment equipment for process treatment of the battery cells. The process treatment of all battery cells can be completed by cycling the above process.

[0050] It can be seen from the working steps of the above-mentioned battery cell circulation equipment that before a group of boat containers 2 with battery cells complete the processing in the process treatment equipment, another group of boat containers 2 remaining in the equipment body 1 has completed cooling and loaded with boats 5 carrying battery cells to be processed. After each process treatment of the process treatment equipment, the middle-level handling component 12 immediately takes out a group of boat containers 2 in the process treatment equipment, and places another group of boat containers 2 remaining in the equipment body 1 in the process treatment equipment in a short time. Therefore, the process treatment equipment does not need to wait for the boat containers 2 to cool down, which can reduce the heat loss of the process treatment equipment and improve the production efficiency of the battery cells.

[0051] See also Figure 5 In some boat carriers 2, two groups of lugs 22 are provided, and the two groups of lugs 22 are spaced apart from each other. When transferring the boat carrier 2 between the upper cache assembly 11 and the middle transport assembly 12, the upper lug 22 can be overlapped with the upper cache assembly 11, and the lower lug 22 can be overlapped with the middle transport assembly 12. When transferring the boat carrier 2 between the middle transport assembly 12 and the lower cache assembly 13, the upper lug 22 can be overlapped with the middle transport assembly 12, and the lower lug 22 can be overlapped with the lower cache assembly 13.

[0052] In other embodiments, a plurality of hanging ears 22 are provided, and the plurality of hanging ears 22 are arranged side by side, and any two of the container supporting structure 14 of the upper cache assembly 11, the container supporting structure 14 of the middle transport assembly 12, and the container supporting structure 14 of the lower cache assembly 13 are arranged in a staggered manner. In this way, when transferring the boat container 2 between any two of the three transport assemblies, namely, the upper cache assembly 11, the middle transport assembly 12, and the lower cache assembly 13, some hanging ears can be overlapped with the one located at the upper side, and other hanging ears can be overlapped with the one located at the lower side, which can also realize the transfer of the boat container 2.

[0053] See also Figure 5 In some boat-carrying containers 2, the hanging ear 22 includes an overlap portion 221 and a limit portion 222. The overlap portion 221 is fixed to the side wall of the container body 21 and overlaps the supporting member 141. The limit portion 222 is fixed to the side of the overlap portion 221 away from the container body 21 and protrudes downward from the bottom wall of the overlap portion 221. In this way, the displacement of the hanging ear 22 in one direction can be limited by the limit portion 222, so as to prevent the boat-carrying container 2 from being separated from the container supporting structure 14.

[0054] See also Figure 5The supporting member 141 is provided with a supporting groove 1411, and the supporting groove 1411 is used to accommodate the hanging ear of the boat container 2. In this way, the hanging ear 22 of the boat container 2 is located between two opposite side walls of the supporting groove 1411. The displacement of the hanging ear 22 can be limited by the two opposite side walls of the limiting groove, which is conducive to the stable transfer of the boat container 2.

[0055] See also Figure 5 The supporting groove 1411 is conformed to the hanging ear 22. This is conducive to the container supporting structure 14 to stably support the boat container 2.

[0056] See also Figure 3 Each container supporting structure 14 further includes a first crossbeam 142 connected to the frame 15. In the same container supporting structure 14, two supporting members 141 are both slidably connected to the first crossbeam 142. Thus, the two supporting members 141 can be moved closer to each other by sliding the two supporting members 141 toward each other, and can be moved away from each other by sliding the two supporting members 141 away from each other.

[0057] See also Figure 3 Each container supporting structure 14 further includes a second crossbeam 143 connected to the frame 15, and the second crossbeam 143 is parallel to the first crossbeam 142. In the same container supporting structure 14, both supporting members 141 are slidably connected to the second crossbeam 143. In this way, the first crossbeam 142 and the second crossbeam 143 jointly define the sliding direction of the supporting member 141, which is conducive to improving the sliding accuracy and stability of the supporting member 141.

[0058] See also Figure 3 Each container support structure 14 further includes two sets of power output assemblies 144 arranged opposite to each other, and each power output assembly 144 is fixedly connected to the first cross beam 142. Each power output assembly 144 includes a seat body and a power output member, and the power output member is connected to the seat body in a sliding / telescopic manner along the length direction of the first cross beam 142. In the same container support structure 14, the two support members 141 are respectively fixed to the power output members of the two power output assemblies 144. In this way, the support member 141 can be driven to slide by the power output member.

[0059] The power output assembly 144 may be a linear module or a cylinder, or may be an electric telescopic rod.

[0060] Preferably, in the horizontal direction, the power output assembly 144 is located between the first cross beam 142 and the second cross beam 143 .

[0061] In some embodiments, the power output assembly 144 may not be provided on the container supporting structure 14, and the supporting member 141 may be driven to slide by a worker / robot / mechanical arm.

[0062] See also Figure 2 The equipment body 1 further includes a lifting assembly 16 and a transverse moving assembly 17. The lifting assembly 16 includes a lifting seat 161 and a lifting member 162. The lifting member 162 is slidably connected to the lifting seat 161 along the vertical direction. The transverse moving assembly 17 includes a transverse moving seat and a transverse moving member. The transverse moving member is slidably connected to the transverse moving seat along the horizontal direction. The middle-level transport assembly 12 is fixed to the transverse moving member. The lifting assembly 16 and the transverse moving assembly 17 can realize the lifting and horizontal movement of the middle-level transport assembly 12.

[0063] In other embodiments, the positions of the lifting assembly 16 and the transverse movement assembly 17 can be interchanged, that is, the lifting assembly 16 is arranged on the transverse movement assembly 17, and the middle-level transport assembly 12 is fixedly arranged on the lifting assembly 16.

[0064] In other embodiments, two electric telescopic rods may be used to replace the lifting assembly 16 and the lateral movement assembly 17 respectively, so as to realize the lifting and horizontal movement of the middle-level transport assembly 12 .

[0065] See also Figure 1 , multiple container support structures 14 are provided on the upper cache assembly 11, the middle transport assembly 12 and the lower cache assembly 13. In this way, the upper cache assembly 11, the middle transport assembly 12 and the lower cache assembly 13 can overlap multiple boat containers 2, and can transfer multiple boat containers 2 at the same time. The middle transport assembly 12 can place multiple boat containers 2 on the process equipment at the same time, which is conducive to improving the production efficiency of the battery cells.

[0066] See also Figure 1 , multiple container support structures 14 on the upper cache assembly 11 / middle transport assembly 12 / lower cache assembly 13 are arranged side by side. This is conducive to fully utilizing the space of the upper cache assembly 11 / middle transport assembly 12 / lower cache assembly 13, and is conducive to reducing the size of the upper cache assembly 11 / middle transport assembly 12 / lower cache assembly 13.

[0067] See also Figure 6 and Figure 7 The battery cell circulation equipment also includes a boat cache vertical warehouse 3, and the boat cache vertical warehouse 3 is arranged side by side with the rack 15. Figure 7 The boat buffer vertical warehouse 3 is provided with a plurality of boat supporting structures 31, and each boat supporting structure 31 is used to place a boat 5. In this way, the boats 5 that need to wait can be stored in the boat buffer vertical warehouse 3, so that the boats 5 that need to wait can be temporarily stored without interrupting the entire production process, so as to balance the production speed of each node on the photovoltaic module production line, prevent the photovoltaic module production line from being overly congested or stagnant, and ensure an efficient process.

[0068] See also Figure 6 and Figure 8The battery cell circulation equipment also includes a fork assembly 4 arranged opposite to the boat buffer warehouse 3. Figure 8 The fork assembly 4 includes a fork seat body 41 and a fork 42. The fork 42 is disposed on the fork seat body 41 so as to be liftable and movable in a horizontal plane so as to enter and exit any boat supporting structure 31. Figure 7 , each boat supporting structure 31 is provided with a fork avoidance space 311 for the fork 42 to pass up and down. In this way, the boat 5 can be placed on any boat supporting structure 31 by the fork 42, or the boat 5 on any boat supporting structure 31 can be taken out by the fork 42. The process of placing the boat 5 on the boat supporting structure 31 by the fork 42 is as follows: the fork 42 moves the boat 5 to the top of the boat supporting structure 31, and then the fork 42 descends and passes through the fork avoidance space 311 on the boat supporting structure 31. The boat 5 cannot pass through the fork avoidance space 311 due to its large size and remains on the boat supporting structure 31. The process of the fork 42 taking out the boat 5 from the boat supporting structure 31 is as follows: the empty fork 42 moves to the bottom of the boat supporting structure 31, then the fork 42 rises and passes through the fork avoidance space 311 on the boat supporting structure 31 to support the boat 5 on the boat supporting structure 31, and then the fork 42 moves horizontally to carry the boat 5 away from the boat cache warehouse 3.

[0069] Specifically, see Figure 8 The fork assembly 4 also includes a lifting member 43 and a transverse member 44. The lifting member 43 can be lifted and lowered on the fork seat body 41, and the transverse member 44 can be lifted and lowered along the fork seat body 41. Figure 8 The fork 42 is arranged on the lifting member 43 so as to be movable horizontally in the Y direction. Figure 8 The transverse member 44 is arranged to be movable horizontally in the X direction.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
