Description

Technical Field

[0001] This application relates to the field of battery cell transportation technology, and in particular to a battery cell tray and battery cell transportation equipment. Background Technology

[0002] During the production and assembly of battery cells, the cells often need to be carried by cell pallets for transportation between different processes. Due to the limited strength of existing cell pallets, the cells and pallets, or even the pallets themselves, will constantly collide during transport, causing the pallets to fail and the cells to be scrapped, resulting in significant cost waste. Utility Model Content

[0003] This application provides a battery cell tray and a battery cell transport device to improve the strength of the battery cell tray, prevent the battery cell tray from failing when carrying battery cells, and reduce cost waste.

[0004] In a first aspect, this application provides a battery cell tray, including a base plate, a carrier, and a plurality of first limiting posts. The carrier and the first limiting posts are all installed on the same side of the base plate. The carrier is used to carry the battery cells. The mechanical strength of the carrier is less than that of the base plate. Along a first direction, the plurality of first limiting posts are respectively located on opposite sides of the carrier and are used to limit the battery cells. The first direction is parallel to the transport direction of the battery cell tray.

[0005] In the battery cell tray described in this application, the base plate, the support member, and the first limiting post are designed as separate units. When the battery cell tray carries the battery cell, the force borne by the first limiting post due to impact is transmitted to the base plate. Since the mechanical strength of the base plate is greater than that of the support member, the base plate will not fail due to collision damage, which helps to improve the strength of the battery cell tray, avoids failure when the battery cell tray carries the battery cell, and reduces cost waste. Moreover, due to the greater mechanical strength of the base plate, collisions between battery cell trays can be avoided, preventing the base plate from breaking and thus avoiding failure when the battery cell tray carries the battery cell, further reducing cost waste.

[0006] The mechanical strength of the first limiting post is greater than that of the bearing member, which ensures the mechanical strength of the first limiting post and prevents it from failing due to collision damage. This helps to improve the strength of the battery cell tray, prevents the battery cell tray from failing when bearing the battery cell, and reduces cost waste.

[0007] The carrier is detachably mounted on the base plate, and / or the first limiting post is detachably mounted on the base plate.

[0008] In the battery cell tray described in this application, the carrier and the first limiting post are detachably assembled with the base plate, and each component can be replaced or repaired individually, saving labor and material costs. Furthermore, the spacing or size of the first limiting post can be adjusted according to the size of the battery cell to improve the adaptability of the battery cell tray to different sized battery cells.

[0009] The first limiting posts are spaced apart from the carrier to avoid interference between the first limiting posts and the carrier during replacement and maintenance, thereby improving the efficiency of replacing and maintaining the first limiting posts and the carrier.

[0010] The battery cell tray further includes a plurality of second limiting posts, which are located on opposite sides of the carrier along a second direction and are used to limit the battery cell. The second direction intersects with the first direction.

[0011] The first limiting post and the second limiting post together limit the battery cell, which can improve the stability of the battery cell tray in supporting the battery cell.

[0012] The base plate has a first side and a second side. Along the first direction, the first side is located on one side of the support member and is spaced apart from the support member. The distance between the first side and the support member is a first distance. Along the second direction, the second side is located on one side of the support member and is spaced apart from the support member. The distance between the second side and the support member is a second distance. The second distance is less than the first distance.

[0013] The first limiting post is located between the bearing member and the first side, and the second limiting post is located between the bearing member and the second side. The mechanical strength of the material of the second limiting post is greater than that of the material of the first limiting post.

[0014] Since the second distance is smaller than the first distance, the area on the base plate used to install the second limiting post is limited. Since the mechanical strength of the material of the second limiting post is greater than that of the material of the first limiting post, the size of the second limiting post can be designed to be very small to achieve high mechanical strength.

[0015] The second limiting post is integrally formed with the bearing member to reduce the number of parts in the battery cell tray, which not only saves the material cost of the battery cell tray, but also saves the assembly process between the parts.

[0016] The battery cell tray further includes a buffer sleeve, which is fitted onto the first limiting post and used to limit the battery cell to provide a buffering effect, avoid rigid collision between the first limiting post and the battery cell, and prevent damage to the battery cell when the battery cell tray carries the battery cell.

[0017] Wherein, the base plate is made of bakelite, and / or the bearing member is made of vacuum forming, and / or the first limiting post is made of bakelite.

[0018] The carrier has multiple grooves spaced apart, with the opening of each groove located on the circumferential surface of the carrier. The groove design facilitates the insertion of tooling beneath the battery cell, enabling the placement and removal of the battery cell from the battery cell tray.

[0019] The groove is offset from the first limiting post to prevent the first limiting post from affecting the tooling extending under the battery cell, so as to realize the picking and placing of the battery cell placed on the battery cell tray.

[0020] Secondly, this application provides a battery cell transport device, including a conveyor belt and any of the aforementioned battery cell trays, wherein the battery cell trays are disposed on the conveyor belt and the transport direction of the battery cell trays is parallel to the transport direction of the conveyor belt.

[0021] In the battery cell tray described in this application, the base plate, the support member, and the first limiting post are designed as separate units. When the battery cell tray carries the battery cell, the force exerted by the first limiting post due to impact is transmitted to the base plate. Since the mechanical strength of the base plate is greater than that of the support member, the base plate will not fail due to collision damage, which helps to improve the strength of the battery cell tray, avoids failure when the battery cell tray carries the battery cell, and reduces cost waste. Moreover, due to the greater mechanical strength of the base plate, collisions between battery cell trays can be avoided, preventing the base plate from breaking and thus avoiding failure when the battery cell tray carries the battery cell, further reducing cost waste.

[0026] The battery cell transport device 100 includes a battery cell 200, a conveyor belt 110, a battery cell tray 120, a base plate 10, a load-bearing component 20, a limiting post 30, a bottom surface 101, a mounting surface 102, a first side surface 103, a second side surface 104, a load-bearing surface 201, a peripheral surface 202, a first peripheral surface 203, a second peripheral surface 204, a groove 205, a first limiting post 31, a second limiting post 32, and a buffer sleeve 40. Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0028] Please see Figure 1 , Figure 1 This is a schematic diagram of the assembly structure of the battery cell transport device 100 and the battery cell 200 provided in this application.

[0029] This application provides a battery cell transport device 100 for transporting battery cells 200. The battery cell transport device 100 includes a conveyor belt 110 and a battery cell tray 120. The battery cell tray 120 is disposed on the conveyor belt 110 and is used to carry the battery cells 200, and the battery cells 200 are transferred between different processes under the drive of the conveyor belt 110.

[0030] Please refer to the following: Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the structure of the battery cell tray 120 in the battery cell transport equipment 100 shown.

[0031] For ease of description, the width direction of the cell tray 120 is defined as the first direction X, the length direction of the cell tray 120 as the second direction Y, and the height direction of the cell tray 120 as the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other. For example, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0032] The battery cell tray 120 includes a base plate 10, a support member 20, and a plurality of limiting posts 30. The support member 20 and the plurality of limiting posts 30 are all mounted on the same side of the base plate 10. The support member 20 is used to support the battery cells 200. The plurality of limiting posts 30 are arranged around the support member 20 at intervals, and are also spaced apart from the support member 20, and are used to limit the battery cells 200.

[0033] In this embodiment, the base plate 10 is a bakelite board. The base plate 10 has a bottom surface 101, a mounting surface 102, two first side surfaces 103, and two second side surfaces 104. Along the thickness direction of the base plate 10 (the third direction Z in the figure), the bottom surface 101 and the mounting surface 102 are arranged opposite to each other. When the battery cell tray 120 is placed on the conveyor belt 110, the bottom surface 101 is in contact with the conveyor belt 110, and the mounting surface 102 is the surface of the base plate 10 facing away from the conveyor belt 110. Along the first direction X, the two first side surfaces 103 are arranged opposite to each other and connected between the bottom surface 101 and the mounting surface 102. The first direction X is parallel to the transport direction of the battery cell tray 120 and parallel to the conveying direction of the conveyor belt 110. Along the second direction Y, the two second side surfaces 104 are arranged opposite to each other and connected between the bottom surface 101 and the mounting surface 102, and also connected between the two first side surfaces 103.

[0034] The carrier 20 is mounted on the mounting surface 102, located between the two first side surfaces 103 and between the two second side surfaces 104, and is spaced apart from both the two first side surfaces 103 and the two second side surfaces 104. Specifically, the carrier 20 is detachably mounted on the mounting surface 102 to facilitate replacement or maintenance of the carrier 20, thereby saving labor costs and expenses. For example, the carrier 20 can be mounted on the mounting surface 102 by riveting. The distance between the carrier 20 and the first side surface 103 is a first distance d1, and the distance between the carrier 20 and the second side surface 104 is a second distance d2, where the second distance d2 is less than the first distance d1.

[0035] In this embodiment, the mechanical strength of the carrier 20 is less than that of the base plate 10. The carrier 20 is a vacuum-formed component. For example, the carrier 20 is vacuum-formed from ABS (acrylonitrile butadiene styrene). The carrier 20 has a carrier surface 201 and a peripheral surface 202. The carrier surface 201 is the surface of the carrier 20 facing away from the mounting surface 102 and is used to carry the battery cell 200. The peripheral surface 202 surrounds the carrier surface 201 and is connected to it. The peripheral surface 202 includes two first peripheral surfaces 203 and two second peripheral surfaces 204. Along a first direction X, the two first peripheral surfaces 203 are arranged opposite to each other and connected to the carrier surface 201. Along a second direction Y, the two second peripheral surfaces 204 are arranged opposite to each other and connected to the carrier surface 201, and are connected between the two first peripheral surfaces 203.

[0036] The carrier 20 is provided with a groove 205, the opening of which is located on the circumferential surface 202 of the carrier 20. Specifically, the opening of the groove 205 is located on the first circumferential surface 203. The groove 205 is recessed from one first circumferential surface 203 to another and penetrates the carrier surface 201. For example, there are four grooves 205, with the opening of every two grooves 205 located on one first circumferential surface 203, and every two grooves 205 are spaced apart along the second direction Y. The design of the grooves 205 facilitates the insertion of tooling under the battery cell 200 to enable the placement and removal of the battery cell 200 placed on the battery cell tray 120.

[0037] Multiple limiting posts 30 are installed on the mounting surface 102, and are spaced apart from the support member 20, the first side 103, and the second side 104. Specifically, the limiting posts 30 are detachably installed on the mounting surface 102, which not only facilitates the replacement or maintenance of the limiting posts 30, saving labor costs and expenses, but also allows for the adjustment of the spacing between the limiting posts 30 or the size of the limiting posts 30 according to the size of the battery cell 200, thereby improving the adaptability of the battery cell tray 120. For example, the limiting posts 30 can be installed on the mounting surface 102 by riveting. Moreover, since the multiple limiting posts 30 are spaced apart from the support member 20, interference with the support member 20 can be avoided when replacing or maintaining the limiting posts 30, improving the efficiency of replacing and maintaining the limiting posts 30.

[0038] The plurality of limiting posts 30 includes a first limiting post 31 and a second limiting post 32. Along the first direction X, the first limiting post 31 is located between the carrier member 20 and the first side surface 103, and is offset from the groove 205 to avoid the first limiting post 31 affecting the removal and dispensing of the battery cell 200. There are multiple first limiting posts 31, located on opposite sides of the carrier member 20 along the first direction X. That is, along the first direction X, some first limiting posts 31 are located on one side of the carrier member 20, and others are located on the other side of the carrier member 20, to jointly limit the carrier member 20 and improve the stability of the battery cell tray 120 when carrying the battery cell 200. For example, there are four first limiting posts 31, located on one side of the carrier member 20 along the first direction X, and spaced apart along the second direction Y.

[0039] In this embodiment, the mechanical strength of the first limiting post 31 is greater than that of the bearing member 20 to ensure the mechanical strength of the first limiting post 31 and prevent it from failing due to collision damage. This helps to improve the strength of the cell tray 120, preventing it from failing when bearing the cell 200 and reducing cost waste. For example, the first limiting post 31 is made of bakelite and can be a solid column.

[0040] It should be noted that when the cell tray 120 carries the cell 200, the first limiting post 31 will collide with the cell 200. The first limiting post 31 is the main stress point. Since the first limiting post 31 is spaced apart from the carrier 20, the force on the first limiting post 31 will be directly transmitted to the base plate 10 without affecting the carrier 20. The mechanical strength of the base plate 10 is greater than that of the carrier 20. The base plate 10 will not be damaged by the force generated by the impact, which helps to improve the strength of the cell tray 120, avoid the failure of the cell tray 120 when carrying the cell 200, and reduce cost waste.

[0041] Along the second direction Y, the second limiting post 32 is located between the carrier 20 and the second side 104. There are multiple second limiting posts 32, located on opposite sides of the carrier 20 along the second direction Y. Some of the second limiting posts 32 are located on one side of the carrier 20, and others are located on the other side, collectively limiting the carrier 20 and improving the stability of the cell tray 120 when carrying the cell 200. For example, there are three second limiting posts 32, with one on one side of the carrier 20 and the other two on the other side, spaced apart along the first direction X.

[0042] In this embodiment, the mechanical strength of the second limiting post 32 is greater than or equal to the mechanical strength of the bearing member 20 to ensure the mechanical strength of the second limiting post 32 and prevent it from failing due to collision damage. This helps to improve the strength of the battery cell tray 120, preventing it from failing when carrying the battery cell 200 and reducing cost waste. The mechanical strength of the material of the second limiting post 32 is greater than that of the material of the first limiting post 31. For example, the second limiting post 32 is made of metal and can be a solid column. It should be noted that since the second distance d2 is smaller than the first distance d1, the area on the base plate 10 for mounting the second limiting post 32 is limited. Because the mechanical strength of the metal material is greater than that of bakelite, the size of the second limiting post 32 can be designed to be very small to achieve high mechanical strength.

[0043] In some other embodiments, the mechanical strength of the second limiting post 32 may be less than that of the first limiting post 31. The material of the second limiting post 32 may be the same as that of the carrier member 20. In this case, the second limiting post 32 can be integrally formed with the carrier member 20 to reduce the number of components in the cell tray 120, saving not only material costs but also assembly steps. It should be understood that since the second limiting post 32 is located on one side of the carrier member 20 in the second direction Y, it is not a primary stress point when the cell tray 120 carries the cell 200. Therefore, the second limiting post 32 does not need high mechanical strength; it only needs to effectively limit the movement of the cell 200.

[0044] In addition, the cell tray 120 also includes multiple buffer sleeves 40, each buffer sleeve 40 being fitted onto a limiting post 30 and used to limit the cell 200. The elastic modulus of the buffer sleeve 40 is less than that of the limiting post 30 to provide a buffering effect, preventing a rigid collision between the limiting post 30 and the cell 200, and avoiding damage to the cell 200 when the cell tray 120 carries the cell 200. For example, the buffer sleeve 40 may be a rubber sleeve.

[0045] In this embodiment, the cell tray 120 features a separate design for the base plate 10, the support member 20, and the limiting post 30. Each component can be replaced or repaired individually, saving labor and material costs. Furthermore, during the transport of the cell 200 by the cell transport equipment 100, when the limiting post 30 collides with the cell 200, the first limiting post 31 distributes the force borne by the limiting post 30 evenly to the base plate 10. Since the mechanical strength of the base plate 10 is greater than that of the support member 20, the base plate 10 is less prone to failure due to collision, thus improving the strength of the cell tray 120 and preventing it from failing while carrying the cell 200, reducing cost waste. Moreover, the greater mechanical strength of the base plate 10 also prevents the base plate 10 from cracking due to collisions between cell trays 120, ensuring the effective support of the cell 200 by the cell tray 120 and reducing cost waste. In addition, the split-type limiting posts 30 can also adjust the spacing between the limiting posts 30 or adjust the size of the limiting posts 30 according to the size of the battery cell 200, so as to improve the adaptability of the battery cell tray 120 to battery cells 200 of different sizes.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
