Description

Technical Field

[0001] The embodiments in this specification relate to the field of battery manufacturing technology and equipment, and in particular to a cell transfer device. Background Technology

[0002] Currently, after the battery cells undergo OCV (Open Circuit Voltage) testing, they need to be manually transported to the battery cell stacking station. Specifically, after the battery cells pass the OCV test, the operators place the qualified battery cells into injection molding trays according to the test sequence and stack them. Then, they are manually transported to the next station for stacking into groups, with each group typically containing 10-17 battery cells.

[0003] However, this process has the following problems: First, when the tested and qualified battery cells are placed in the injection molding trays, since each tray can only hold two cells, the trays are usually stacked to save storage space. If the stacked trays exceed five layers, the center of the tray is prone to collapse after being lifted. Therefore, each group of battery cells needs to be handled in 2-3 trips, which is inefficient and carries the risk of scratching the cells by the edges of the trays. Second, after transfer, the battery cells need to be removed from the trays. Because the cells are stacked and handled multiple times, employees cannot identify the original OCV testing order of the cells. When stacking and removing them at the next workstation, the cells will be disordered, making it impossible to effectively trace the cell data.

[0004] In view of this, the embodiments of this specification are intended to provide a battery cell transfer device. Utility Model Content

[0006] To solve the above-mentioned technical problems, the specific technical solutions of the embodiments in this specification are as follows:

[0007] This specification provides a battery cell transfer device, including a base plate, outer side plates, a spacer plate, and a rear side plate. The base plate is provided with a first screw hole, a second screw hole, and a third screw hole.

[0008] Specifically, multiple spacers are provided, and the multiple spacers are evenly spaced on the base plate, and the multiple spacers are arranged parallel to the outer side plate.

[0009] Specifically, a space for placing a battery cell is formed between two adjacent spacers, between the spacer closest to the outermost plate and the corresponding outermost plate, and the height of the outermost plate and the spacers is greater than or equal to half the height of the battery cell.

[0010] Preferably, the rear panel is provided with a number, and the number corresponds one-to-one with the space used to place the battery cell.

[0011] Preferably, the outer side plate is chamfered on both the side away from the rear side plate and the side away from the bottom plate; the partition plate is chamfered on both the side away from the rear side plate and the side away from the bottom plate.

[0012] Preferably, the outer corners of the outer side plate and the outer corners of the partition plate are both rounded.

[0013] Furthermore, the gripper has an elongated oval groove.

[0014] Preferably, the gripper is tilted, and the angle between the gripper and the horizontal direction is in the range of 5° to 15°.

[0015] Preferably, the edges of the gripper are chamfered.

[0030] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

[0031] It should be noted that the terms "first," "second," etc., used in this specification, claims, and the foregoing drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0032] To address the aforementioned problems, this specification provides a battery cell transfer device. Specifically, as shown in the embodiments... Figures 1 to 4 As shown, the cell transfer device may include a base plate 20, an outer side plate 30, a spacer plate 40, and a rear side plate 50;

[0033] The base plate 20 is provided with a first screw hole 201, a second screw hole 202 and a third screw hole 203;

[0034] The outer side plate 30 is disposed on both sides of the base plate 20 through the third screw hole 203, and the outer side plate 30 is provided with a gripper 302;

[0035] The rear side plate 50 is disposed on the rear side of the base plate 20 through the first screw hole 201 and is connected to the outer side plate 30.

[0036] The spacer plate 40 is disposed on the base plate 20 through the second screw hole 202 and is located between the outer plates 30.

[0037] This specification provides an embodiment of a battery cell transfer device, wherein a rear side plate 50 and two outer side plates 30 surround the rear and left and right sides of a base plate 20, forming the main body of the battery cell transfer device. A spacer plate 40 is detachably connected to the base plate 20 via a second screw hole 202, creating spaces for placing battery cells 10 between adjacent spacers 40 and between the spacer plate 40 closest to the outer side plate 30 and its corresponding outer side plate 30, thus facilitating the batch storage and transfer of battery cells. In this embodiment, the first screw hole 201 and the third screw hole 203, being the fixing screw holes for connecting the rear side plate 50 and the outer side plates 30 to form the main body of the battery cell transfer device and serving as the main force-bearing parts, can have an opening radius of R4. The second screw hole 202, used to connect the spacer plate 40 and act as a spacer, experiences less force; therefore, the opening radius of the second screw hole 202 can be set to R2.

[0038] like Figure 2 As shown in the embodiments of this specification, the base plate 20 is provided with multiple rows of second screw holes 202 for connecting the spacers 40. In practical applications, at least some of the second screw holes 202 can be selected as needed; that is, the number of spacers 40 can be the same as the number of rows of second screw holes 202, or it can be less than the number of second screw holes 202. By connecting each spacer 40 to the second screw holes 202 in different rows, the distance between two adjacent spacers 40 can be adjusted, thereby meeting the stacking and transportation requirements of battery cells with different sizes. Therefore, the battery cell transportation device provided in the embodiments of this specification can not only stack battery cells in batches and improve the transportation efficiency of battery cells, but also meet the stacking and transportation requirements of battery cells of different sizes and specifications by adjusting the position of each spacer 40 on the base plate 20, which is beneficial to improving the compatibility of the transportation device and reducing the design and development cost of the transportation device.

[0039] It should be noted that the battery cell transfer device provided in this embodiment of the specification also includes a structure to improve connection stability between the rear side plate 50 and the outer side plates 30 located on both sides. For example, an opening is provided at the connection between the rear side plate 50 and the outer side plate 30 so that bolts or other connecting parts can pass through the opening to connect the rear side plate 50 and the outer side plate 30. Alternatively, slots are provided on the outer side plates 30 on both sides, and the two sides of the rear side plate 50 are respectively inserted into the slots connected to the outer side plates 30 on both sides.

[0040] like Figure 1 and Figure 4 As shown, multiple spacer plates 40 are provided, and the multiple spacer plates 40 are evenly spaced on the base plate 20, and the multiple spacer plates 40 are arranged parallel to the outer side plate 30.

[0041] By arranging the spacers 40 evenly spaced and parallel to the outer side plate 30 on the base plate 20, the number of battery cells that can be stacked on a single battery cell transfer device can be increased, thereby improving the space utilization of the battery cell transfer device.

[0042] Specifically, a space for placing the battery cell 10 is formed between two adjacent spacers 40, between the spacer 40 closest to the outermost plate 30 and the corresponding outermost plate 30, and the height of the outermost plate 30 and the height of the spacer 40 are both greater than or equal to half the height of the battery cell 10.

[0043] By ensuring that the height of the outer side plate 30 and the height of the spacer plate 40 are both greater than or equal to half the height of the battery cell 10, the outer side plate 30 and the spacer plate 40 have sufficient support for the battery cell. At the same time, the height of the outer side plate 30 and the height of the spacer plate 40 can be less than or equal to three-quarters of the height of the battery cell 10, so that the battery cell 10 still has sufficient exposed area after being stacked and placed in the battery cell transfer device, so that the operator can easily pick it up.

[0044] In some preferred embodiments, the rear panel 50 is provided with a number, which corresponds one-to-one with the space for placing the battery cell 10.

[0045] The serial number can be set on the rear panel 50 by photolithography. After the battery cell 10 has undergone the previous process test, the operator can place the battery cell 10 in the various storage spaces of the battery cell transfer device according to the test sequence; after being transferred to the next workstation, the battery cells 10 can be taken out and stacked into groups according to the serial number sequence. The serial number facilitates the sequential storage of battery cells and the traceability of battery cell test data according to the serial number.

[0046] In some preferred embodiments, the outer side plate 30 is chamfered on both the side away from the rear side plate 50 and the side away from the bottom plate 20; similarly, the partition plate 40 is chamfered on both the side away from the rear side plate 50 and the side away from the bottom plate 20.

[0047] By chamfering the outer contours of the non-connected parts of the outer side plate 30 and the outer contours of the non-connected parts of the spacer plate 40, damage or defects caused by collisions between the outer contours of the outer side plate 30 and the spacer plate 40 and the battery cell can be avoided during the storage / removal of the battery cell 10.

[0048] Furthermore, the outer corners 301 of the outer side plate 30 and the outer corners of the spacer plate 40 are both rounded. That is, the outer corners 301 of the outer side plate 30 and the outer corners of the spacer plate 40 are smooth rounded to prevent collisions with the battery cells and to improve the overall aesthetic appearance of the battery cell transfer device.

[0049] As shown in Figure 3, in some feasible embodiments, the gripper 302 is an oblong slot.

[0050] By making the gripper 302 an elongated oval slot on the outer side plate 30, it is not necessary to add additional handles or other components; thus, the battery cell transfer device is in the shape of a regular cuboid, which makes it easier to save space when multiple battery cell transfer devices are stacked close together.

[0051] In some preferred embodiments, the gripper 302 is inclined, and the angle between the gripper 302 and the horizontal direction is in the range of 5° to 15°.

[0052] Specifically, the gripper 302 forms a 10° angle with the horizontal direction.

[0053] By tilting the gripper 302, it is possible to make it more convenient and labor-saving for operators to move the battery cell transfer device when stacking and storing battery cells.

[0054] More preferably, the gripper 302 has chamfered edges.

[0055] That is, a chamfer 303 is provided at the elongated edge of the gripper 302 to improve the comfort of the operator when handling the battery cell transfer device.

[0056] In some feasible embodiments, the base plate 20 is further provided with an outer surrounding plate (not shown in the figure) on one side of the rear side plate 50.

[0057] By adding an external enclosure plate on the opposite side of the rear panel 50, the stability of the cell transfer device when transferring the cells placed therein can be improved.

[0058] It should be noted that when the battery cells 10 are stacked and placed in the battery cell transfer device provided in the embodiments of this specification, the battery cell tabs 101 are placed facing the opening of the device to prevent the battery cell tabs 101 from being squeezed and deformed. The placement method is as follows: Figure 1 As shown.

[0059] The cell transfer device provided in the embodiments of this specification can increase the number of cells transferred by more than 2 times compared with the case where the cell transfer device provided in the embodiments of this specification is not used, which greatly improves the transfer efficiency and increases the production efficiency by 50-66% (see Table 1 below).

[0060] It can also replace the original injection molding tray for transportation, avoiding damage to the battery cells during handling and transportation, and improving the product qualification rate by 6% (see Table 1 below);

[0061] Operators perform tasks according to the numbers on the cell transfer device. After the cells are grouped, the test data of the cells in the previous process can be queried by number sequence to achieve point-to-point traceability (see Table 1 below).
