[0036] Energy saving and emission reduction is the key to sustainable development, which promotes the adjustment of energy structure and the development and application of battery technology. The key to the development of battery technology is electrochemical energy storage technology, which has been widely used in portable electronics, electric vehicles and energy storage systems due to its high energy density, good cycle ability, high working voltage, environmental protection and low self-discharge.

[0037] The battery shell protects the battery cell, and whether the production and manufacturing of the battery shell meets the standard is an important indicator of whether the battery cell is qualified. After the battery shell is manufactured and shaped, the battery shell is manually fixed by manual fixing, and then the battery shell is measured. However, this fixing method is prone to problems such as battery shell shaking during measurement.

[0038] To solve the technical problems in the related art, the application further provides a battery shell fixing device and a detection system. The battery shell fixing device comprises a mounting plate, a shell positioning block and a fixing assembly. The shell positioning block is arranged on the mounting plate and is used for assembling a battery shell. The fixing assembly is arranged on the mounting plate in a spaced manner with the shell positioning block. The fixing assembly is used for abutting against the battery shell from a side of the battery shell away from the shell positioning block, so that the fixing assembly cooperates with the shell positioning block to fix the battery shell. In this way, the fixing assembly is used for abutting against the battery shell from a side of the battery shell away from the shell positioning block, so that the fixing assembly cooperates with the shell positioning block to fix the battery shell. The risk of battery shell shaking during measurement caused by manual fixing of the battery shell can be improved, the fixing effect of the battery shell is improved, and the accuracy and reliability of the detection of the battery shell are further improved.

[0039] Specifically, referring to Figure 1 , Figure 1 is a structural schematic diagram of a detection system according to one or more embodiments of the application.

[0040] The detection system 1 comprises a detection device 20 and a battery shell fixing device 10. The battery shell fixing device 10 can be used for fixing a battery shell. The detection device 20 can be used for detecting the fixed battery shell, for example, the detection device 20 can be used for detecting the shape of the battery shell, or detecting the size of the battery shell, such as detecting the size of the mouth of the battery shell, and the like.

[0041] The battery shell can be a shell of a battery monomer. For example, the battery shell can be a component used for cooperating with an end cover to form an internal environment of a battery monomer, wherein the formed internal environment can be used for accommodating an electrode assembly, an electrolyte and other components. The battery shell and the end cover can be independent components. An opening can be arranged on the battery shell. The end cover is made to cover the opening to form the internal environment of the battery monomer through the opening. The end cover and the battery shell can form a common connecting surface before other components enter the shell. When it is necessary to seal the inside of the battery shell, the end cover is made to cover the battery shell. The battery shell can be of various shapes and sizes, such as a cuboid, a cylinder, a hexagonal prism, and the like. Specifically, the shape of the battery shell can be determined according to the specific shape and size of the electrode assembly. The material of the battery shell can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic and the like.

[0042] The detection device 20 can include a controller and an image acquisition module. After the battery shell fixing device 10 fixes the battery shell, the controller can control the image acquisition module to acquire images of the corresponding positions of the battery shell, then perform image recognition on the images to obtain relevant shell data, and then compare the shell data with preset shell data to finally determine whether the size of the battery shell meets the standard. In other embodiments, the detection device 20 can also include other components, and the detection device 20 can also detect the battery shell through any feasible embodiment in the related art.

[0043] Referring to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of a battery shell fixing device according to one or more embodiments of the present application. Figure 3 is a structural schematic diagram of a battery shell fixing device fixing a battery shell according to one or more embodiments of the present application.

[0044] The battery shell fixing device 10 includes a mounting plate 300, a shell positioning block 200, and a fixing assembly 100. The shell positioning block 200 is arranged on the mounting plate 300 and is used to assemble the battery shell 30. The fixing assembly 100 is arranged on the mounting plate 300 in a spaced manner with the shell positioning block 200, and is used to abut against the battery shell 30 from a side of the battery shell 30 away from the shell positioning block 200, so that the fixing assembly 100 cooperates with the shell positioning block 200 to fix the battery shell 30.

[0045] The mounting plate 300 can be flat, and the mounting plate 300 can be placed flat on other platforms. The shell positioning block 200 can be fixed on the mounting plate 300, for example, the shell positioning block 200 can be detachably connected with the mounting plate 300 by means of bolts or the like, or the shell positioning block 200 can be fixedly connected with the mounting plate 300 by means of welding or the like. The battery shell 30 can be a shell of a battery monomer. The shape of the shell positioning block 200 can correspond to the shape of the inner side wall of the battery shell 30. For example, when the battery shell 30 is a square shell, the part of the shell positioning block 200 used to assemble the battery shell 30 can be square, and when the battery shell 30 is a cylindrical shell, the part of the shell positioning block 200 used to assemble the battery shell 30 can be cylindrical. The outer dimensions of the part of the shell positioning block 200 used to assemble the battery shell 30 can be slightly smaller than the dimensions of the inner side wall of the battery shell 30, thereby facilitating the assembly of the battery shell 30 on the outside of the shell positioning block 200.

[0046] After the battery shell 30 is assembled outside the shell positioning block 200, the fixing assembly 100 can abut against the battery shell 30 from the side of the battery shell 30 away from the shell positioning block 200, for example, the fixing assembly 100 can abut against the battery shell 30 from different side walls of the battery shell 30 and / or abut against the battery shell 30 from the bottom wall of the battery shell 30, so that the battery shell 30 and the shell positioning block 200 are kept relatively fixed. The fixing assembly 100 can include but is not limited to automatic and manual modes. For example, after the battery shell 30 is assembled to the shell positioning block 200, the fixing assembly 100 can abut against the battery shell 30 from the side of the battery shell 30 away from the shell positioning block 200 after detecting that the battery shell 30 is in a predetermined position. Alternatively, the fixing assembly 100 can abut against the battery shell 30 from the side of the battery shell 30 away from the shell positioning block 200 after receiving a relevant control instruction. Alternatively, after the battery shell 30 is assembled to the shell positioning block 200, the fixing assembly 100 can be manually abutted against the battery shell 30 from the side of the battery shell 30 away from the shell positioning block 200.

[0047] According to the above embodiment, the fixing assembly 100 is used to abut against the battery shell 30 from the side of the battery shell 30 away from the shell positioning block 200, so that the fixing assembly 100 cooperates with the shell positioning block 200 to fix the battery shell 30. This can improve the risk of shaking of the battery shell 30 during measurement caused by manual fixing of the battery shell 30, improve the fixing effect of the battery shell 30, and further improve the accuracy and reliability of detection of the battery shell 30.

[0048] Further, the fixing assembly 100 includes a magnetic attraction member 110, which is used to magnetically attract the shell positioning block 200 from the side of the battery shell 30 away from the shell positioning block 200. The number of the magnetic attraction member 110 can be set according to actual conditions, for example, the magnetic attraction member 110 can be one, two, three or more. At least part of the shell positioning block 200 is a ferromagnetic material part that can be magnetically attracted by the magnetic attraction member 110. When the battery shell 30 is assembled outside the shell positioning block 200, the battery shell 30 blocks the ferromagnetic material part of at least part of the shell positioning block 200, and the magnetic attraction member 110 cooperates with the ferromagnetic material part to magnetically attract the shell positioning block 200 from the side of the battery shell 30 away from the shell positioning block 200, so that the magnetic attraction member 110 cooperates with the shell positioning block 200 to fix the battery shell 30. This can realize rapid fixing of the battery shell 30 on the basis of reducing damage to the battery shell 30, and improve the accuracy and efficiency of detection of the battery shell 30.

[0049] Furthermore, the battery casing fixing device 10 also includes a stop 400, which is disposed on the mounting plate 300 and is used to hold the magnetic component 110. The stop 400 can be detachably connected to the mounting plate 300 by bolts or other means, or the casing positioning block 200 can be fixedly connected to the mounting plate 300 by welding or other means. The shape of the stop 400 can be set according to the actual situation, such as... Figure 2 As shown, the stop member 400 may be L-shaped. A portion of the stop member 400 is connected to the mounting plate 300, and another portion extends away from the mounting plate 300. The magnetic member 110 is fixed to the other portion of the stop member 400. The stop member 400 may be made of a ferromagnetic material. When it is not necessary for the magnetic member 110 to magnetically attach to the housing positioning block 200 from the side of the battery housing 30 away from the housing positioning block 200, the magnetic member 110 can be placed in the stop member 400 for storage. In some other embodiments, the stop member 400 may also have a receiving groove, allowing the magnetic member 110 to be placed in the receiving groove for storage when it is not necessary for the magnetic member 110 to magnetically attach to the housing positioning block 200 from the side of the battery housing 30 away from the housing positioning block 200.

[0050] Furthermore, the number of stop members 400 is at least two, and at least two stop members 400 are located on the side of the housing positioning block 200 facing the bottom wall of the battery housing 30. The number of stop members 400 can be set according to actual conditions; for example, the number of stop members 400 can be two, three, four, or more. The number of stop members 400 can correspond to the number of magnetic suction members 110, that is, each stop member 400 can be used to place at least one magnetic suction member 110. The at least two stop members 400 can be arranged at intervals, and at least two stop members 400 are located on the side of the housing positioning block 200 facing the bottom wall of the battery housing 30. Figure 2 and Figure 3 As shown, there can be two stop members 400. Both stop members 400 are located on the side of the housing positioning block 200 facing the bottom wall of the battery housing 30, and the two stop members 400 are spaced apart. The distance between the two stop members 400 can be greater than the width of the housing positioning block 200. If viewed along a direction perpendicular to the distance between the two stop members 400, the housing positioning block 200 can be located between the two stop members 400. Correspondingly, after the battery housing 30 is mounted on the housing positioning block 200, the distance between the two stop members 400 can be slightly greater than the width of the battery housing 30, and the battery housing 30 can also be located between the two stop members 400. Therefore, when the battery housing 30 is not fixed, it is difficult for the battery housing 30 to detach from the housing positioning block 200 and exit the mounting plate 300 between the two stop members 400. Thus, the stop members 400 restrict the battery housing 30 from excessively detaching from the housing positioning block 200 on the side facing the bottom wall of the battery housing 30, reducing the risk of damage to the battery housing 30 during testing.

[0051] In some embodiments, the mounting plate 300 comprises a mounting surface 310, and the housing positioning block 200 and the fixing assembly 100 are arranged on the mounting surface 310, and the surface of the housing positioning block 200 facing the bottom wall of the battery housing 30 is perpendicular to the mounting surface 310. The mounting surface 310 can be a flat surface, and when the mounting plate 300 is placed horizontally on other platforms, the mounting surface 310 can be placed horizontally, i.e., the mounting surface 310 can be perpendicular to the direction of gravity. As shown in Figure 2 and Figure 3 The surface of the housing positioning block 200 facing the bottom wall of the battery housing 30 is perpendicular to the mounting surface 310, which can allow the housing positioning block 200 to be placed horizontally relative to the mounting surface 310, and correspondingly, when the battery housing 30 is assembled on the housing positioning block 200, the battery housing 30 can also be placed horizontally relative to the mounting surface 310. In this embodiment, the housing positioning block 200 can comprise two parts, one part of the housing positioning block 200 is directly fixed on the mounting surface 310, and the other part of the housing positioning block 200 used for assembling the battery housing 30 has a gap with the mounting surface 310, thereby facilitating the assembly of the battery housing 30 on the housing positioning block 200 without being affected by the mounting surface 310, and improving the risk of damage to the battery housing 30 during the fixing of the battery housing 30.

[0052] Further, the battery housing fixing device 10 comprises a mounting reference member 700, and the mounting plate 300 is connected with the mounting reference member 700, and the mounting reference member 700 comprises at least one mounting reference edge 710. The specific shape of the mounting reference member 700 can be set according to actual conditions, and the mounting reference member 700 can comprise the mounting reference edge 710, as shown in Figure 2 and Figure 3 The mounting reference edge 710 can be two perpendicular straight edges, and when the mounting plate 300, the fixing assembly 100 and the housing positioning block 200 are fixed, the mounting reference edge 710 can be used as a reference to accurately arrange the housing positioning block 200 and the fixing assembly 100 at the predetermined position of the mounting plate 300, thereby improving the convenience of operation. The fixing mode of the mounting reference member 700 and the mounting plate 300 can be set according to actual conditions, for example, the mounting plate 300 can be in the form of a flat plate, the edge of the mounting reference member 700 can have an embedded groove, and the edge of the mounting plate 300 can be inserted into the embedded groove to realize the plug-in fit of the mounting plate 300 and the mounting reference member 700.

[0053] In some embodiments, the fixing assembly 100 comprises at least two driving fixing members 120, the two driving fixing members 120 are located on both sides of the shell positioning block 200, and the at least one driving fixing member 120 comprises a fixing block 122 and a driving member 121, the driving member 121 is connected with the fixing block 122, and the driving member 121 is used to drive the fixing block 122 to be close to or away from the shell positioning block 200. The driving fixing member 120 can be two, and the two driving fixing members 120 are located on both sides of the shell positioning block 200, so as to facilitate the cooperation of the shell positioning block 200 and the fixing of the battery shell 30 from both sides of the shell positioning block 200.
