Description

Technical Field

[0001] The present invention relates to the field of automatic storage and transportation of battery cells, and in particular to a battery cell detection and circulation device and a battery cell detection and circulation method. Background Art

[0002] Battery cells are the raw materials for battery module production. The performance consistency of battery cells in battery modules has a great impact on product performance. In order to ensure the product quality of battery modules, it is necessary to perform OCV (Open Circuit Voltage) tests on battery cells. For example, a series of tests such as OCV3 and OCV4 are required, and battery cells are classified and processed based on the inspection data.

[0003] As the degree of automation in the field of battery cell production continues to increase, the overall efficiency of the battery cell production line is also continuously improving, so the efficiency requirements for battery cell detection and storage circulation are also increasing accordingly. At present, battery cells are mostly stored in a storage location in a normal temperature warehouse. One stacker can only carry one battery cell pallet at a time. This storage method is not only inefficient, but also occupies a large space per unit storage volume, and has a high unit storage cost. In addition, the demand for stackers is large, and increasing the number of stackers will bring higher costs.

[0004] Normal temperature warehouses need to store battery cell pallets of various processes. In order to improve storage efficiency, reduce the number of stackers and reduce costs, the prior art also has a solution of transporting multiple battery cell pallets at one time through a stacker. However, transporting too many pallets at one time will make it difficult to pair the batteries entering and leaving the warehouse with pallets of the same process. The stacker must not only handle the entry and exit of pallets carrying battery cells, but also be used for the circulation of pallets without battery cells. This limits the stacker's carrying capacity. The efficiency of battery cell detection circulation in the prior art is low. Even if multiple battery cell pallets are transported at one time by a stacker, a large number of stackers are still required to maintain normal operating efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the technical problem of low efficiency of battery cell detection and circulation in the prior art. The present invention provides a battery cell detection and circulation device, which can effectively reduce the workload of the stacker and effectively improve the efficiency of battery cell detection and circulation.

[0006] In order to solve the above technical problems, the embodiment of the present invention discloses a battery cell detection flow device, comprising:

[0007] The first and second storage locations;

[0008] A normal temperature warehouse, used for a stacker to deliver a plurality of trays carrying battery cells from the first storage location or the second storage location to the normal temperature warehouse, or used for the stacker to deliver a plurality of trays carrying battery cells from the normal temperature warehouse to the first storage location or the second storage location;

[0009] A first warehousing line is used to transfer the plurality of pallets carrying battery cells to the first storage location, and the stacker is used to transfer the plurality of pallets carrying battery cells in the first storage location to the normal temperature storage;

[0010] The first detection circuit is used to transfer the plurality of trays carrying battery cells in the normal temperature warehouse to the first battery cell detection device, and to transfer the plurality of trays carrying battery cells detected by the first battery cell detection device to the first storage location, and the stacker is used to send the plurality of trays carrying battery cells detected by the first battery cell detection device into the normal temperature warehouse;

[0011] The second detection circuit is used to transfer the plurality of trays carrying battery cells in the normal temperature warehouse to the second battery cell detection device, and to transfer the plurality of trays carrying battery cells detected by the second battery cell detection device to the second storage location, and the stacker is used to send the plurality of trays carrying battery cells detected by the second battery cell detection device into the normal temperature warehouse;

[0012] A first outbound route is used to send out the pallet carrying the battery cells detected by the second battery cell detection device from the second storage location, and the pallet carrying the battery cells becomes a pallet without battery cells after passing through the first outbound route;

[0013] An empty pallet return line is connected to the first outbound line and is used to return the pallets without battery cells to the first inbound line. The stacker is not used to transport the pallets without battery cells.

[0014] With the above technical solution, multiple trays carrying battery cells are transported from the first storage line to the first storage location, and the stacker transports the multiple trays carrying battery cells into the normal temperature storage and leaves them to stand, so as to perform the first normal temperature process on the battery cells.

[0015] After the first normal temperature process, the plurality of trays carrying the battery cells are transported to the first battery cell testing device through the first testing line for the first battery cell testing (eg, performing OCV3 testing on the battery cells).

[0016] After the first battery cell inspection, the multiple trays carrying the battery cells are returned to the first storage location through the first inspection line and are put into storage by the stacker and left to stand for the second normal temperature process.

[0017] After the second room temperature process, the plurality of trays carrying the battery cells are transported to the second battery cell testing device through the second testing line for a second battery cell test (eg, an OCV4 test on the battery cells).

[0018] After the second battery cell inspection, multiple trays carrying battery cells are returned to the second storage location through the second inspection line and are put into storage by the stacker and left to stand for the third normal temperature process.

[0019] After the third normal temperature process, multiple pallets loaded with battery cells are shipped out through the first outbound route. After multiple battery cells enter the next process (such as encapsulation), pallets without battery cells are returned to the first inbound route through the empty pallet return route. There is no need for stackers to participate in the circulation of pallets without battery cells, which can reduce the workload of the stackers and improve the working efficiency of the stackers, thereby improving the overall efficiency of battery cell detection and circulation, reducing the number of stackers used, and reducing costs. In addition, through the above technical solution, two battery cell inspections and three normal temperature process treatments can be carried out in an orderly manner, which can further speed up the working efficiency of battery cell detection and circulation, so as to improve the overall efficiency of the battery cell production line.

Exemplarily, the battery cell detection circulation device also includes a stacker 21, a first storage position 22 and a second storage position 23, the first storage position 22 and the second storage position 23 are arranged at intervals on both sides of the normal temperature warehouse 20 in the first direction X, and along the first direction X, the stacker 21 can be movably switched between the first storage position 22 and the second storage position 23, and is used to store or unstore multiple pallets carrying battery cells in the first storage position 22 or the second storage position 23. Storage can be understood as sending multiple pallets carrying battery cells located in the first storage position 22 or the second storage position 23 into the normal temperature warehouse 20, and unloading can be understood as sending multiple pallets carrying battery cells located in the normal temperature warehouse 20 to the first storage position 22 or the second storage position 23.

[0099] It can be understood that the embodiment of the present application does not limit the positions of the first storage location 22 and the second storage location 23. For example, the first storage location 22 and the second storage location 23 are spaced apart on both sides of the normal temperature warehouse 20 in the third direction Z.

[0100] In some embodiments, see Figure 1 , Figure 2 The normal temperature warehouse 20 includes a first shelf 201 and a second shelf 202. The first shelf 201 and the second shelf 202 are arranged at intervals along the third direction Z. A passage 203 is defined between the first shelf 201 and the second shelf 202. The stacker 21 is movably arranged in the passage 203 along the first direction X. For example, refer to Figure 1 , Figure 2 The first shelf 201 and the second shelf 202 both include two columns of storage locations 2012 spaced apart along a third direction Z, each column of storage locations includes 10 storage locations 2012, and each storage location 2012 stores two trays 2013 carrying battery cells.

[0101] Further, the stacker 21 referred to in the embodiment of the present application is used to store multiple pallets carrying battery cells in the first storage location 22 or the second storage location 23, that is, the stacker 21 is used to transfer and store multiple pallets carrying battery cells in the first storage location 22 or the second storage location 23 in the storage location 2012, and the stacker 21 referred to in the embodiment of the present application is used to remove multiple pallets carrying battery cells from the first storage location 22 or the second storage location 23, that is, the stacker 21 is used to transfer and move multiple pallets carrying battery cells in the storage location 2012 to the first storage location 22 or the second storage location 23 for subsequent process operations. Exemplarily, the empty pallet return line 60 is arranged in the bottom space 2011 of the first shelf 201, and is spaced from the storage location 2012 of the first shelf 201 along the second direction Y.

[0102] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The stacker 21 includes a frame 211 and a guide rail 212. The guide rail 212 is arranged on the channel 203 and extends along the first direction X. The first shelf 201 and the second shelf 202 are arranged on both sides of the guide rail 212 in the third direction Z. The frame 211 is provided with a walking mechanism (not shown in the figure), and the walking mechanism drives the frame 211 to move along the guide rail 212. Exemplarily, the stacker 21 also includes a lifting mechanism 213 and a fork-picking mechanism 214. The lifting mechanism 213 is connected to the fork-picking mechanism 214 and is used to drive the fork-picking mechanism 214 to move up and down along the second direction Y. The fork-picking mechanism 214 includes a fork plate 2141 and a telescopic component 2142. The telescopic component 2142 is connected to the fork plate 2141 and is used to make the fork plate 2141 reciprocate along the third direction Z. Exemplarily, the stacker 21 can be a high-speed stacker or a double-station stacker, etc., and the embodiment of the present application does not limit the type of the stacker 21.

[0103] It should be noted that the connection relationship between the first inbound line 10, the normal temperature warehouse 20, the first detection line 30, the second detection line 40, the first outbound line 50 and the empty pallet return line 60 described below includes but is not limited to being connected by a track formed by multiple horizontally arranged rollers, or being connected by a conveyor belt.

[0104] In some embodiments, see Figure 4 , Figure 5 Combined with Figure 1 The first warehousing line 10 is connected to the first storage location 22 and is used to transfer multiple pallets carrying battery cells to the first storage location 22 . The stacker 21 is used to send multiple pallets carrying battery cells in the first storage location 22 into the normal temperature warehouse 20 .

[0105] One end of the first detection circuit 30 is connected to the first storage location 22, and the other end of the first detection circuit 30 is used to connect to the first battery cell detection device 71, and is used to transfer the multiple trays carrying battery cells in the normal temperature warehouse 20 to the first battery cell detection device 71, and is used to transfer the multiple trays carrying battery cells that have been detected by the first battery cell detection device 71 to the first storage location 22. The stacker 71 is used to send the multiple trays carrying battery cells that have been detected by the first battery cell detection device 71 into the normal temperature warehouse 20.

[0106] One end of the second detection circuit 40 is connected to the second storage location 23, and the other end of the second detection circuit 40 is used to connect to the second battery cell detection device 72, and is used to transfer the multiple trays carrying battery cells in the normal temperature warehouse 20 to the second battery cell detection device 72, and is used to transfer the multiple trays carrying battery cells that have been detected by the second battery cell detection device 72 to the second storage location 23. The stacker 71 is used to send the multiple trays carrying battery cells that have been detected by the second battery cell detection device 72 into the normal temperature warehouse 20.

[0107] The first outbound route 50 is connected to the second storage location 23, and is used to send out the pallets carrying the battery cells detected by the second battery cell detection device 72 from the second storage location 23. The pallets carrying the battery cells pass through the first outbound route 50 to become pallets without battery cells (such as Figure 2 As shown in 601, for example, when the tray carrying the battery cells is sent to the next process (such as the encapsulation process, etc.) by the first outbound line 50, the battery cells are taken away by the next process, leaving the tray without the battery cells.

[0108] One end of the empty pallet return line 60 is connected to the first inbound line 10, and the other end is connected to the first outbound line 50, and is used to return the pallets without cells from the first outbound line 50 to the first inbound line 10, and the stacker 21 is not used to carry the pallets without cells. Exemplarily, the empty pallet return line 60 is connected to the first inbound line 10 through a hoist (not shown in the figure), and the hoist can transfer the pallets without cells to the empty pallet return line 60.

[0109] Exemplarily, the first inbound line 10, the first detection line 30, the second detection line 40, the first outbound line 50 and the empty pallet return line 60 are all transmission lines composed of a plurality of rollers arranged at intervals horizontally.

[0110] With the above technical solution, multiple trays carrying battery cells are transported from the first storage line 10 to the first storage location 22, and the stacker 21 delivers the multiple trays carrying battery cells to the normal temperature storage 20 and leaves them to stand, so as to perform the first normal temperature process on the battery cells.

[0111] After the first normal temperature process, the plurality of trays carrying the battery cells are transported to the first battery cell testing device 71 through the first testing circuit 30 for the first battery cell testing (eg, performing OCV3 testing on the battery cells).

[0112] After the first battery cell inspection, the plurality of trays carrying the battery cells are returned to the first storage location 22 via the first inspection line 30 and are put into storage by the stacker 21 and left to stand for the second normal temperature process.

[0113] After the second room temperature process, the plurality of trays carrying the battery cells are transported to the second battery cell testing device 72 through the second testing circuit 40 for a second battery cell testing (eg, performing an OCV4 test on the battery cells).

[0114] After the second battery cell inspection, the plurality of trays carrying the battery cells are returned to the second storage location 23 via the second inspection line 40 and are put into storage by the stacker 21 and left to stand for the third normal temperature process.

[0115] After the third normal temperature process, multiple pallets carrying battery cells are shipped out through the first outbound line 50. After multiple battery cells enter the next process (such as encapsulation), the pallets without battery cells are returned to the first inbound line 10 through the empty pallet return line 60. There is no need for the stacker 21 to participate in the circulation of pallets without battery cells, which can reduce the workload of the stacker 21 and improve the working efficiency of the stacker 21, thereby improving the efficiency of the battery cell detection circulation as a whole, reducing the number of stackers 21 used, and reducing costs. In addition, through the above technical solution, two battery cell inspections and three normal temperature process treatments can be carried out in an orderly manner, which can further speed up the working efficiency of the battery cell detection circulation to improve the overall efficiency of the battery cell production line.

[0116] In some embodiments, see Figure 4 , Figure 5 , the empty pallet return line 60 includes a first part 61, a second part 62 and a third part 63. Along the second direction Y, the first part 61 is spaced apart from the first inbound line 10, the third part 63 is spaced apart from the first outbound line 50, the second part 62 runs through the normal temperature warehouse 20 along the first direction X, and along the second direction Y, the second part 62 is spaced apart from the first shelf 201, and both ends of the second part 62 are connected to the first part 61 and the third part 63 respectively. The second direction Y is the height direction of the battery cell detection circulation equipment, such as a direction perpendicular to the ground. Exemplarily, the projection of the empty pallet return line 60 in the second direction Y overlaps with the projection of the first inbound line 10, the normal temperature warehouse 20 and the first outbound line 50 in the second direction Y.

[0117] For example, see Figure 4 , Figure 5 The first storage route 10 includes a first branch line 11 and a second branch line 12, which are connected by a lifting and transplanting device 80. The first branch line 11 and the second branch line 12 form an "L"-shaped first storage route 10, and the lifting and transplanting device 80 can be used to transfer multiple trays carrying battery cells from the first branch line 11 to the second branch line 12. Correspondingly, the first part 61 is also set in an "L" shape. The embodiment of the present application does not limit the shape of the first branch line 11 and the second branch line 12. For example, the first branch line 11 and the second branch line 12 can also be connected along the first direction X to form a "one" shape, and the lifting and transplanting device 80 is not required.

[0118] For example, see Figure 4 , Figure 6, the first outbound route 50 includes a third branch line 51 and a fourth branch line 52, the third branch line 51 and the fourth branch line 52 are connected by a lifting and transplanting device 80, the third branch line 51 and the fourth branch line 52 form an "L"-shaped first outbound route 50, and the lifting and transplanting device 80 can be used to transfer a plurality of trays carrying battery cells from the third branch line 51 to the fourth branch line 52. Correspondingly, the third part 63 is also set in an "L" shape. The embodiment of the present application does not limit the shape formed by the third branch line 51 and the fourth branch line 52. For example, the third branch line 51 and the fourth branch line 52 can also be connected along the first direction X to form a "one" shape, and in this case, there is no need to set the lifting and transplanting device 80.

At the second height h2, the third lifting platform 2221 is flush with the seventh storage platform 2223, which is used for the stacker 21 to fork at least 4 trays carrying battery cells at a time.

[0125] In some embodiments, see Figure 4 , Figure 5 , Figure 6The fourth sub-storage position 232 includes a fourth lifting platform 2321, a sixth storage platform 2322 and an eighth storage platform 2323.

At the second height h2, the fourth lifting platform 2321 is flush with the eighth storage platform 2323, which is used for the stacker 21 to fork at least 4 trays carrying battery cells at a time.

[0126] In the above embodiments, the first height h1 is smaller than the second height h2. The first storage platform 2212, the third storage platform 2312, the fifth storage platform 2222 and the sixth storage platform 2322 have the same structure. For ease of understanding, the first storage platform 2212 will be used as an example for description below.

[0127] For example, see Figure 5 , Figure 7 , Figure 8 The first storage platform 2212 includes a base 22120, on which are provided a first conveyor belt 22121 and a second conveyor belt 22122 extending along a third direction Z. The first conveyor belt 22121 and the second conveyor belt 22122 are spaced apart along the first direction X to jointly define a first forking space 22123. The first conveyor belt 22121 and the second conveyor belt 22122 have a first length L1 in the third direction Z, and the first length L1 is at least twice a second length L2 in the third direction Z of two trays carrying battery cells stacked in the second direction Y.

[0128] Exemplarily, the first conveyor belt 22121 and the second conveyor belt 22122 jointly define a first conveying surface in contact with the bottom of the tray, and the area of ​​the first conveying surface is at least twice the bottom area of ​​the tray carrying the battery cells, that is, the first conveying surface can be used to place at least two adjacent trays carrying the battery cells in the third direction Z.

[0129] Exemplarily, the first conveying surface includes a first placement area 22124 and a second placement area 22125, and the first placement area 22124 and the second placement area 22125 are arranged at intervals along the third direction Z. Both the first placement area 22124 and the second placement area 22125 can be used to place a plurality of trays carrying battery cells stacked along the second direction Y.

At this time, each group of conveyor belts corresponds to a placement area, and the length of the two groups of conveyor belts in the third direction is a first length L1. The area of ​​the conveying surface defined by each group of conveyor belts is not less than the area of ​​the pallet, so that each placement area is used to place multiple pallets carrying battery cells stacked along the second direction Y.

[0131] Exemplarily, when the first placement area 22124 and the second placement area 22125 are respectively loaded with two trays loaded with battery cells stacked along the second direction Y, the fork plate of the stacker can move along the third direction Z to the first forking space 22123, and deliver the two trays loaded with battery cells stacked along the second direction Y into the normal temperature warehouse 20 at one time. Exemplarily, when two trays loaded with battery cells are stacked along the second direction Y, the embodiment of the present application can deliver four trays loaded with battery cells into the normal temperature warehouse 20 at one time.

[0132] It can be understood that the present application does not limit the number of areas on the first conveying surface for placing trays carrying battery cells. Specifically, the areas on the first conveying surface can be divided into 1, 3, 4, 5, 6, 7 or other numbers according to conditions such as the size of the tray.

[0137] The carrying portion 22111 includes a fifth conveyor belt 22118 and a sixth conveyor belt 22119, which are arranged at intervals along the first direction X, and a roller 22113 is arranged between the fifth conveyor belt 22118 and the sixth conveyor belt 22119. The fifth conveyor belt 22118 and the sixth conveyor belt 22119 can be used together to transfer the tray carrying the battery cells from the first placement area 22124 to the second placement area 22125, leaving space for the first placement area 22124 to receive a new tray carrying the battery cells. The first height h1 in the above-mentioned embodiment refers to the height between the surface of the fifth conveyor belt 22118 and the sixth conveyor belt 22119 and the ground, and at the second height h2, the surface of the fifth conveyor belt 22118 and the sixth conveyor belt 22119 is flush with the second conveying surface 22134.

There is no need for a stacker to participate in the circulation of pallets without cells, which can reduce the workload of the stacker and improve the working efficiency of the stacker, thereby improving the efficiency of the cell detection circulation as a whole, reducing the number of stackers used, and reducing costs. In addition, through the above technical solution, two cell detections and three normal temperature process treatments can be carried out in an orderly manner, which can further speed up the working efficiency of the cell detection circulation and improve the overall efficiency of the cell production line.
