[0002] In the battery production process, the battery after entering the shell is loaded by a tray and transported by a linear body, so as to complete the transfer of the battery between the production line processes. In the battery transfer process, the battery in the tray is usually grabbed by a mechanical hand gripper to the internal station of the equipment for processing, and the processed battery is grabbed by the mechanical hand and sent back to the tray so as to be transferred to the next process. When the battery model of the production line changes, the battery height changes, and in order to meet the battery transfer requirements, different models of trays are usually used to match the corresponding battery models. In the prior art, one battery tray can only hold one model of battery, and one specification of battery tray is configured to produce one model of battery. The battery tray does not have compatibility, has poor universality, low utilization rate, and high production, use and storage costs of the battery tray, which causes unnecessary waste. SUMMARY

[0003] To solve the problems in the prior art, the present application provides a battery tray and a use method thereof. Different specifications of batteries can be held in one battery tray, the universality and utilization rate of the battery tray are improved, and the production, use and storage costs of the battery tray are reduced.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0005] In a first aspect, a battery tray is provided, comprising: a tray frame, the inside of the tray frame is provided with a plurality of battery limiting grooves for accommodating batteries, the battery limiting grooves have a first limiting height; a first auxiliary module for increasing the limiting height of the battery limiting grooves to a second limiting height; a second auxiliary module for increasing the limiting height of the battery limiting grooves to a third limiting height; wherein the third limiting height is greater than the second limiting height.

[0006] The above-mentioned technical scheme changes the limiting height of the battery limiting grooves by setting the first auxiliary module and the second auxiliary module, so that different specifications of batteries can be kept stable in the battery tray, and the mechanical hand can easily take and place the batteries, thereby realizing that one battery tray can hold different specifications of batteries, improving the universality and utilization rate of the battery tray, and reducing the production, use and storage costs of the battery tray.

[0007] Further, the opening end of the battery limiting groove is provided with a guide bevel for facilitating the placement of the battery into the battery limiting groove.

[0008] The technical scheme has the advantages that the guiding groove is arranged, the opening end diameter of the battery limiting groove 101 is slightly larger than the diameter of the battery, the battery is convenient to take and place, the success rate of the robot arm in taking and placing the battery is improved, and the production efficiency is improved.

[0010] The technical scheme has the advantages that the inner liner is arranged in the tray frame to increase the limiting height of the battery limiting groove. When the size of the battery becomes larger, the tray frame alone cannot meet the requirement for the stability of the battery, and the inner liner increases the limiting height of the battery limiting groove and improves the stability of the battery.

[0011] Further, the first limiting hole is provided with a guiding groove facilitating the placement of the battery into the battery limiting groove.

[0016] The technical scheme has the advantages that the supporting columns are arranged between the inner liner and the tray frame to further increase the limiting height of the battery limiting groove. When the size of the battery becomes larger, the combination of the tray frame and the inner liner alone cannot meet the requirement for the stability of the battery, and the inner liner and the supporting columns jointly increase the limiting height of the battery limiting groove and further improve the stability of the battery.

When the size of the battery becomes larger and the height exceeds the height of the side wall of the tray frame, it is not conducive to the stacking of the battery tray, and a large amount of space is occupied to store the battery tray, causing space waste. At this time, by installing the height-increasing block provided with the stacking groove, the height of the side wall of the tray frame is increased, so that the battery does not protrude from the tray frame, which is conducive to the stacking of the battery tray and saves the storage space of the battery tray.

[0022] (1)

[0023] If the limiting height of the battery limiting groove is the first limiting height, the relationship (1) is met, and the battery tray does not need to be assembled, and the tray frame is directly used to hold the battery; if the limiting height of the battery limiting groove is the second limiting height, the relationship (1) is met, the inner liner is installed in the tray frame, and the assembled battery tray is used to hold the battery; if the limiting height of the battery limiting groove is the third limiting height, the relationship (1) is met, the support column is installed between the tray frame and the inner liner, and the assembled battery tray is used to hold the battery.

[0024] The technical scheme quantifies the matching relationship between the battery and the battery tray, provides a specific operation method for selecting the battery tray according to the size of the battery, facilitates the operator to quickly judge and select the battery tray, and improves the production efficiency.

[0039] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0040] Example 1

[0041] During the process of a robotic arm grasping batteries from a tray, the tray needs to effectively limit the battery's position while also allowing a certain height of the battery to be grasped by the robotic arm to protrude. Typically, one-third of the battery's total height protrudes from the tray to meet the robotic arm's grasping requirements. A battery height limited to at least half its original height within the tray also meets the limiting requirements and satisfies the stability requirements for battery positioning during line transport. Therefore, when the battery model or height changes on the production line, this invention provides a battery tray to meet the battery transport requirements, such as... Figures 1-10 As shown, the device includes a tray frame 1, a first auxiliary module, and a second auxiliary module. The tray frame 1 has a plurality of battery limiting grooves 101 for accommodating batteries 15. Each battery limiting groove 101 has a first limiting height. The first auxiliary module is used to increase the limiting height of the battery limiting groove 101 to a second limiting height. The second auxiliary module is used to increase the limiting height of the battery limiting groove 101 to a third limiting height. The third limiting height is greater than the second limiting height, which is greater than the first limiting height.

[0042] By setting the first auxiliary module and the second auxiliary module to change the limiting height of the battery limiting groove 101, batteries of different specifications can be kept stable in the battery tray, and the robotic arm can easily pick up and put in the batteries. This enables a battery tray to hold a variety of batteries of different specifications, improves the versatility and utilization of the battery tray, and reduces the production, use and storage costs of the battery tray.

[0043] The opening end of the battery limiting groove 101 is provided with a guide bevel to facilitate the insertion of the battery 15 into the battery limiting groove 101.

[0044] The opening end diameter of the battery limiting groove 101 is slightly larger than the diameter of the battery 15 by setting the guide groove, so that the battery 15 is conveniently taken and placed, the success rate of the robot in taking and placing the battery 15 is improved, and the production efficiency is improved.

[0045] The first auxiliary module comprises the inner liner 2; the inside of the tray frame 1 is provided with a plurality of first mounting columns, and the inner liner 2 is provided with a first mounting hole 202 corresponding to the first mounting column; and the inner liner 2 is further provided with a first limiting hole 201 corresponding to the battery limiting groove 101.

[0046] When the specification of the battery 15 is large, and only the tray frame 1 is used to contain the battery 15, the stability of the battery 15 cannot be met, the inner liner 2 is installed in the tray frame 1 to increase the limiting height of the battery limiting groove 101. When installing, the first mounting hole 202 on the inner liner 2 is installed in one-to-one correspondence with the first mounting column on the tray frame 1, after installation, the first limiting hole 201 on the inner liner 2 corresponds to the battery limiting groove 101 in the tray frame 1 in one-to-one correspondence, the battery 15 is loaded into the battery limiting groove 101 through the first limiting hole 201, the inner liner 2 increases the limiting height of the battery limiting groove 101, and the stability of the battery 15 is improved.

[0047] The first limiting hole 201 is provided with a guide groove for facilitating the placement of the battery 15 into the battery limiting groove 101.

[0048] The guide groove is provided on the first limiting hole 201, and the guide groove makes the opening end diameter of the first limiting hole 201 slightly larger than the diameter of the battery 15, so that the battery 15 is conveniently taken and placed, the success rate of the robot in taking and placing the battery 15 is improved, and the production efficiency is improved.

[0049] The tray frame 1 and the inner liner 2 are positioned by the positioning assembly 7.

[0050] The positioning assembly 7 is arranged between the tray frame 1 and the inner liner 2, so that the inner liner 2 and the tray frame 1 can be quickly positioned and installed, and the installation efficiency is improved. The specific structure of the positioning assembly 7 can be specifically set according to the internal space of the tray frame 1. In the present application, the first positioning hole is arranged in the tray frame 1, and the second positioning hole matched with the first positioning hole is arranged on the inner liner 2, the first positioning hole and the second positioning hole are connected by a bolt, on the one hand, the positioning accuracy of the inner liner 2 and the tray frame 1 is improved, and on the other hand, the stability between the inner liner 2 and the tray frame 1 is improved, so that the inner liner 2 cannot be easily moved, thereby avoiding the problem that the battery tray cannot be used due to the relative sliding between the inner liner 2 and the tray frame 1.

The support column 3 is installed between the inner liner 2 and the tray frame 1 and is connected by bolts to increase the limiting height of the battery limiting groove 101.

[0052] When the specification of the battery 15 becomes larger, the combination of the tray frame 1 and the inner liner 2 cannot meet the requirement of the stability of the battery 15, and the support column 3 is installed between the inner liner 2 and the tray frame 1 to further increase the limiting height of the battery limiting groove 101. During installation, the second mounting hole 301 of the support column 3 is installed on the first mounting column of the tray frame 1, and the first mounting hole 202 on the inner liner 2 is installed on the second mounting column 302 of the support column 3.

During installation, a support column 3 is also added between the first positioning hole and the second positioning hole, which can improve the positioning accuracy of the inner liner 2 and the tray frame 1 and the stability of the connection.

[0053] The second auxiliary module further comprises a plurality of heightening blocks 4 installed on the side wall of the tray frame 1; the side wall of the tray frame 1 and the heightening block 4 are both provided with a stacking groove.

[0054] The heightening block 4 is used to increase the height of the side wall of the tray frame 1. When the specification of the battery 15 becomes larger and its height exceeds the height of the side wall of the tray frame 1, it is not conducive to the stacking of the battery tray, and a large amount of space will be occupied to store the battery tray, causing waste of space; at this time, the heightening block 4 needs to be installed, and by installing the heightening block 4, the height of the side wall of the tray frame 1 is increased to ensure that the battery 15 does not protrude from the tray frame 1, which is conducive to the stacking of the battery tray and saves the storage space of the battery tray.

The tray frame 1 includes four inner liner mounting areas and four heightening block mounting areas. The mounting grooves between the bottom plate of the tray frame 1 and the inner liner 2 can be shared with the support column 3, which are connected by bolt assembly. By installing different accessories in the tray frame 1 and their combination, the same battery tray of the production line can be compatible with the use requirements of different models of cylindrical batteries.

[0056] The tray frame 1 is a square symmetrical structure, and a probe avoidance hole 6 is arranged at the position corresponding to the battery 15 at the bottom. The probe avoidance hole 6 is used to protect the probe and prevent the probe from being damaged. Figure 2 The tray frame 1 and the inner liner 2 are provided with hollow cooling holes around the battery limiting grooves. The bottom of the tray frame 1 includes four positioning steel sleeves 5 of the same size, which are integrally formed by injection molding. The positioning steel sleeve 5 is used for positioning the battery tray. The tray frame 1 is internally provided with battery limiting grooves 101, inner liner 2 and mounting holes of support column 3. The mouth part and the bottom part of the tray frame 1 are respectively provided with a mouth part stacking groove 17 and a bottom part stacking groove 18, and the tray frames can be stacked for use.

[0057] The internal features of the tray frame 1 can limit the battery 15.

The heightening block mounting hole 9 cooperates with the bolt 12 and the nut 13 to mount the heightening block 4 on the side wall of the tray frame 1. Figure 1 、 Figure 3 、 Figure 5 as shown.

[0058] As shown in Figure 4 , the tray frame 1 can be used with four inner liners 2. The part of the battery below the inner liner is suitable for battery limiting, and the part of the battery above the inner liner is suitable for mechanical hand grabbing. The battery limiting length should be greater than or equal to the battery grabbing length. It prevents the battery from falling due to shaking and other factors during transfer, resulting in battery positioning failure, grabbing difficulty and other abnormalities.

[0059] As shown in Figure 5 , the tray frame 1 is respectively provided with a label 14 and a label placement area 11, and a plurality of carrying handles 19. The carrying handle 19 facilitates tray carrying. The label 14 and the label placement area 11 are integrally formed with the tray frame 1 by injection molding. The label 14 is engraved with the tray material and the use process, which facilitates the production line to distinguish and manage.

[0061] As shown in the drawings, Figure 2 , Figure 5 As shown, the tray frame 1 is provided with four positioning steel sleeves 5 and a foolproof opening 16, and a reference corner 10.

[0062] As shown in the drawings, Figure 7 As shown, the overall length L3 of the battery is equal to the battery limiting length (i.e. the limiting height of the battery limiting groove 101) L2 plus the battery grabbing length L1.

[0063] As shown in the drawings, Figures 1-4 As shown, when the overall length L3 of the battery 15 is small, only the tray frame 1 is used for limiting; when the overall length L3 of the battery 15 is moderate, by installing the inner liner 2 on the tray frame 1, the transfer requirement of the battery 15 can be met. When the overall length L3 of the battery 15 is large, by installing the heightening block 4 on the side wall of the tray frame 1 and installing the support column 3 at the bottom of the inner liner 2, the transfer requirement of the battery 15 can be met.
