Description

Technical Field

[0001] The utility model relates to the technical field of battery module transportation, and in particular, to a transfer tray and system for battery pack modules. Background Art

[0002] The transfer tray for battery pack modules is used to fix the battery pack modules and flow from the current working station to the next working station.

[0003] The existing transfer trays for battery pack modules are generally made by injection molding in one piece, and each transfer tray can only be applicable to one type of battery pack module.

It is very difficult for the same type of transfer tray for battery pack modules to meet the requirements of battery pack module production. If an integral tray is designed for each type of battery pack module, it will cause waste of tray design time and tray cost. Summary of the Utility Model

[0043] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0044] As described in the background art, the existing battery pack module transfer tray 10 is generally made by injection molding in one piece. Each transfer tray can only be applicable to one type of battery pack module. However, in actual situations, the sizes of battery pack modules vary greatly. Therefore, it is very difficult for the same type of battery pack module transfer tray 10 to meet the requirements of battery pack module production. If an integral tray is designed for each type of battery pack module, it will cause waste of tray design time and tray cost.

[0045] In view of this, the embodiments of the present utility model provide a battery pack module transfer tray 10 and a system. The battery pack module transfer tray 10 includes a chassis 11, two first pallets 12, and four first limit members 13. By adjusting the positions of the first pallets 12 and the first limit members 13 to adapt to battery pack modules of different sizes and shapes, various-shaped battery pack modules can be loaded onto the tray, thereby saving the design time of the transfer tray and the cost of the transfer tray.

[0046] The following will give an exemplary description of the battery pack module transfer tray 10 provided by the embodiments of the present utility model:

[0047] Please refer to Figure 1 , Figure 1FIG. 0 is one of the structural schematic diagrams of a battery pack module transfer tray 10 provided by an embodiment of the present invention. The battery pack module transfer tray 10 includes a chassis 11, two first pallets 12, and four first limiters 13. A plurality of first bolt holes 111 are formed in the chassis 11. A plurality of second bolt holes 121 and limit through holes 122 are formed in the first pallet 12. The first pallet 12 can be fixed to any position of the chassis 11 by using fixing bolts to pass through the limit through holes 122 and the first bolt holes 111. The first limiter 13 includes a first support base 131 and two first limit baffles 132 provided on two adjacent sides of the first support base 131. A limit through hole 122 is formed in the first support base 131. The first limiter 13 can be fixed to the first pallet 12 by using fixing bolts to pass through the limit through hole 122 and the second bolt holes 121. The two first pallets 12 are arranged in parallel. The two first limiters 13 are arranged on one first pallet 12. The four first limiters 13 are arranged oppositely to support and fix the four corners of the battery pack module.

[0048] As Figure 1 can be seen, the battery pack module transfer tray 10 includes three layers. The bottom layer is the chassis 11, which is the foundation of the entire battery pack module transfer tray 10. A plurality of first bolt holes 111 are formed in the chassis 11. The first pallet 12 is placed on the chassis 11. Limit through holes 122 are formed in the first pallet 12. It can be fixed by using fixing bolts to pass through the limit through holes 122 and the first bolt holes 111 on the chassis 11, and the first pallet 12 can be fixed at any position on the chassis 11. Since the sides of the battery pack module are all straight edges, the two first pallets 12 are arranged in parallel. Second bolt holes 121 are also formed in the first pallet 12, and their function is to fix the first limiter 13 provided on the first pallet 12. Limit through holes 122 are also formed in the first limiter 13. It can be fixed by using fixing bolts to pass through the limit through holes 122 and the second bolt holes 121 on the first pallet 12. Since there are four corners on the bottom surface of the battery pack module, for example, cube, cuboid, convex-shaped body, concave-shaped body, etc., the first limiter 13 is needed to support and fix the four corners. The first limiter 13 includes a first support base 131 and two first limit baffles 132 provided on two adjacent sides of the first support base 131. The first support base 131 is used to place the battery pack module. The two first limit baffles 132 are respectively used to limit the two sides of the corner of the battery pack module. Referring to Figure 1 , the two first limiters 13 are arranged on one first pallet 12, and one first limit baffle 132 of the two first limiters 13 is arranged relatively far away, while the other first limit baffle 132 is arranged away from the other first pallet 12. The battery pack module can be fixed and limited through this setting method.

[0049] An example of the specific setting method of the first limiting component will be given below. We call the intersection point of the first limiting baffle 132 of the first limiting member 13 the included angle of the first limiting member 13. If the bottom surface of the battery pack module is square, just set the vertical connection lines of the included angles of the four first limiting members 13 to form a square. If the bottom surface of the battery pack module is rectangular, just set the vertical connection lines of the included angles of the four first limiting members 13 to form a square, or just set the vertical connection lines of the included angles of the four first limiting members 13 to form a rectangle. If the bottom surface of the battery pack module is convex-shaped, then the two first limiting members 13 on one first support plate 12 need to be set closer, and the two first limiting members 13 on the other first support plate 12 need to be set farther apart.

[0050] By flexibly adjusting the two first support plates 12 and the four first limiting members 13, the battery pack module transfer tray 10 can be used to load battery pack modules of different sizes and shapes. Thus, only one such battery pack module transfer tray 10 is needed to complete the loading and transfer of the battery pack module, without designing a separate transfer tray for different battery modules, saving the design time of the transfer tray and the production cost of the transfer tray.

[0051] In a possible implementation, in order to limit the battery pack module more firmly, the battery pack module transfer tray 10 may further include at least one second support plate 14 and at least one second limiting member 15 to further limit the battery pack module.

[0052] Please refer to Figure 2 , Figure 2 FIG. 2 is a second structural schematic diagram of a battery pack module transfer tray 10 provided by an embodiment of the present invention. The second support plate 14 is disposed parallel between the two first support plates 12. The second support plate 14 is provided with a plurality of third bolt holes 141 and limiting through holes 122. A fixing bolt can be used to fix the second support plate 14 at any position of the chassis 11 through the limiting through holes 122 and the third bolt holes 141. The second limiting member 15 includes a second support base 151 and a second limiting baffle 152 disposed on one side of the second support base 151. The second support base 151 is provided with a limiting through hole 122.

[0053] By providing at least one second support plate 14 between the two first support plates 12, and a second limiting member 15 is disposed on the second support plate 14. The second support plate 14 is parallel to the first support plate 12, and the structure of the second limiting member 15 is different from that of the first limiting member 13. The second limiting member 15 has only one second limiting baffle 152. Therefore, this component will be in the middle of the battery pack module and only needs to limit one side of the battery pack module. In this way, the battery pack module can be limited more firmly.

[0054] Further, a third limiting member 16 can also be provided on the first pallet 12 to limit and fix the battery pack module. Please refer to Figure 3 , Figure 3 FIG. 3 is a schematic structural view of a battery pack module transfer pallet 10 provided by an embodiment of the present invention. The battery pack module transfer pallet 10 further includes at least one third limiting member 16. The third limiting member 16 includes a third support base 161 and a third limiting baffle 162 provided on one side of the third support base 161. A limiting through hole 122 is formed on the third support base 161. The third limiting member 16 is provided on the first pallet 12 and is located between two first limiting members 13.

[0055] The third limiting baffle 162 has the same structure as the second limiting baffle 152, both having only one-sided limiting baffles. However, the installation directions of the two are different. In this way, the limitation of the battery pack module can be made more secure.

[0056] Among them, Figure 2 , Figure 3 The implementation methods can be realized separately or simultaneously.

[0057] Optionally, in order to better adjust the position of the first pallet 12, the first bolt holes 111 are arranged at intervals, and every four adjacent first bolt holes 111 form a square, so as to facilitate the adjustment of the position of the first pallet 12.

[0058] Optionally, in order to make the first pallet 12 and the first limiting member 13 fixed more firmly, the limiting through hole 122 can be set as a loop hole, which can accommodate at least two fixing bolts. The first pallet 12 and the first limiting member 13 are fixed by a plurality of fixing bolts to achieve the purpose of firm fixation.

[0059] Further, the existing battery pack module transfer pallet 10 is a whole structure design and does not have the function of dust prevention for the battery pack. However, during the transfer process of the battery pack module, if it is not protected, it is very easy to be affected by dust and other sundries. Seriously, it will also cause a short circuit inside the module.

[0060] In view of this, in a possible implementation manner, please refer to Figure 4 , Figure 4FIG. 4 is a schematic structural view of a battery pack module transfer tray 10 provided by an embodiment of the present utility model. The battery pack module transfer tray 10 further includes four slide bars 210, two cross beams 220, a first pull rod 230, a second pull rod 240, and a rolling curtain. The four slide bars 210 are respectively arranged at the four corners of the chassis 11. Among them, one cross beam 220 is connected to the two slide bars 210 through a slider 211, so that the cross beam 220 can slide up and down along the slide bars 210, and the other cross beam 220 is oppositely arranged on the other two slide bars 210; the slider 211 is fixed to the slide bar 210 through a first locking bolt 212; notches are respectively formed on one side of the two cross beams 220 close to each other, and both ends of the first pull rod 230 and the second pull rod 240 are arranged in the two notches, and the first pull rod 230 and the second pull rod 240 can slide along the cross beam 220; hooks 250 are respectively arranged on one side of the first pull rod 230 and the second pull rod 240 close to each other, and the rolling curtain is installed between the first pull rod 230 and the second pull rod 240 and fixed by the hooks 250.

[0061] It can be seen from Figure 4 that at the four corners of the chassis 11, four slide bars 210 are vertically arranged perpendicular to the chassis 11. Sliders 211 are arranged on the slide bars 210, and the sliders 211 can be fixed to the slide bars 210 through the first locking bolts 212. A cross beam 220 is arranged between the two slide bars 210 and connected through the slider 211, and the cross beam 220 can slide along with the sliding of the slider 211. Notches are formed on the inner side of the cross beam 220, and the first pull rod 230 and the second pull rod 240 are placed in the notches and can slide along with the notches. Hooks 250 are respectively arranged on one side of the first pull rod 230 and the second pull rod 240 close to each other, and the hooks 250 are used to fix and install the rolling curtain. Through this structural arrangement, for battery pack modules of different heights, they can be adapted by adjusting the sliders 211 up and down. After the battery pack modules are loaded onto the tray, by pulling the first pull rod 230 and the second pull rod 240, the rolling curtain is driven to unfold to provide dust protection for the battery pack modules.

[0062] Optionally, in order to facilitate the pulling control of the rolling curtain, the first pull rod 230 can be fixed. Referring again to Figure 4 , a hole is formed at one end of the cross beam 220, and the first pull rod 230 can be fixed by a second locking bolt 231 through the hole.

[0063] Further, in order to facilitate the pulling of the second pull rod 240, a handle 241 can be arranged at one end of the second pull rod 240 away from the first pull rod 230.

[0064] Through the above arrangement, the pulling control of the rolling curtain can be very convenient, and it is also very convenient to operate with one hand.

[0065] To further protect the battery pack module, the material of the rolling curtain can be antistatic material, which can reduce the generation and accumulation of static electricity, thereby reducing the risk of damage to the battery pack caused by electrostatic discharge.

[0066] Based on the above implementation manner, the embodiment of the present utility model further provides a battery pack module transfer system, including a battery pack module transfer tray 10 and a conveyor belt. The battery pack module transfer tray 10 is used for loading the battery pack module, and the conveyor belt is used for transferring the battery pack module transfer tray 10.

[0067] In summary, for a battery pack module transfer tray 10 and system provided by the embodiment of the present utility model, the battery pack module transfer tray 10 includes a chassis 11, two first pallets 12 and four first limit members 13. By adjusting the positions of the first pallets 12 and the first limit members 13 to adapt to battery pack modules of different sizes and shapes, the battery pack modules of various shapes can be loaded, thereby saving the design time and cost of the transfer tray. Dust protection for the battery pack module is also achieved through the settings of the sliding rod 210, cross beam 220, first pull rod 230, second pull rod 240 and the rolling curtain.
