When positioning batteries of different sizes, it takes time to disassemble and replace the positioning device. The long time spent leads to long production line downtime, affecting production efficiency.

[0033] In order to solve the technical problem, the utility model provides a battery cell positioning device for positioning battery cells of different sizes.

[0034] See also Figures 1 to 3 The battery cell positioning device includes: a mounting frame 10 and a pressing assembly 30, the mounting frame 10 is formed with a mounting groove 11, the mounting groove 11 is used to place the battery cell 20, and the groove wall of the mounting groove 11 is provided with at least two mounting holes 12;

[0035] The pressing assembly 30 includes a first pressing member 31 and a second pressing member 32. The first pressing member 31 is inserted into one mounting hole 12, and the second pressing member 32 is inserted into another mounting hole. The insertion direction of the second pressing member 32 is set at an angle to the insertion direction of the first pressing member 31. The first pressing member 31 is moved along the first direction to fix the battery cell 20 to one groove wall of the mounting groove 11, and the second pressing member 32 is moved along the second direction to press and fix the battery cell to the other groove wall of the mounting groove 11.

[0036] The battery cell positioning device is mainly composed of a mounting frame and a pressing assembly. The mounting frame is provided with a mounting groove, which is specially used to place the battery cell. At least two mounting holes are opened on the groove wall to facilitate the installation of the pressing assembly. The pressing assembly is composed of a first pressing member and a second pressing member, which are respectively inserted into two different mounting holes of the mounting groove. The insertion directions of the first pressing member and the second pressing member are at an angle to each other. This arrangement allows the battery cell to be accurately positioned and fixed by moving the pressing member in different directions.

[0037] In specific operation, the battery cell can be fixed on one side of the installation slot by moving the first pressing member in the first direction; at the same time, the second pressing member moves in the second direction to press and fix the battery cell on the other side of the installation slot. This two-way pressing mechanism not only ensures the stability of the battery cell, but also provides sufficient adjustment space to accommodate battery cells of different sizes, thus eliminating the need to frequently replace the fixture, significantly improving the flexibility and efficiency of the production line.

[0038] Combination Figures 1 to 3 As shown, in the embodiment of the utility model, the battery cell positioning device further includes a driving assembly 40, the driving assembly 40 includes a first driving member 41 and a first connecting member 42, and the first driving member 41 is connected to the bottom surface of the mounting frame 10 away from the notch of the mounting groove 11;

[0041] The first driving member 41 is connected to the first connecting member 42, and the first driving member 41 passes through the mounting frame to directly drive the first connecting member 42. The first pressing member 31 is connected to the first connecting member 42 through the connecting member and is located on the same side of the first driving member 41. Such a layout enables the first driving member 41 to directly drive the first connecting member 42, thereby driving the first pressing member 31 to move along the first direction.

[0042] When the first driving member 41 is activated, it transmits force to the first connecting member 42, causing the first pressing member 31 to move along a predetermined direction, thereby achieving accurate contact or separation of the battery cell 20. This arrangement not only simplifies the operation process, but also improves the accuracy and repeatability of positioning, ensures the stability of the battery cell during the welding process, and thus improves the overall quality and performance of the battery.

[0043] Combination Figures 1 to 3 As shown, in an embodiment of the utility model, the first pressing member 31 includes a first pressing portion 311 and two first connecting portions 312. The first pressing portion 311 is used to abut against the battery cell 20. The two first connecting portions 312 are connected to the surface of the first pressing portion 311 away from the battery cell 20 at intervals. The two first connecting portions 312 are respectively penetrated through the two mounting holes 12 and connected to the first connecting member 42.

[0044] In this embodiment, the first pressing member 31 is composed of a first pressing portion 311 and two first connecting portions 312. The first pressing portion 311 is the portion that directly contacts the battery cell 20 and is tightly matched with the surface of the battery cell to achieve stable positioning and fixation. The two first connecting portions 312 are located on the back of the first pressing portion 311, that is, the surface away from the battery cell 20. They are spaced apart on the first pressing portion 311 to facilitate connection with the mounting hole 12 of the mounting frame 10.

[0045] The two first connection parts 312 are respectively inserted into the two mounting holes 12 on the mounting frame 10, and are connected to the first connection member 42 through a certain connection mechanism. This arrangement not only provides a stable support for the first pressing member 31 on the mounting frame 10, but also realizes the precise movement of the first pressing member 31 along the first direction through the connection between the first connecting member 42 and the driving assembly 40. When the first driving member 41 is activated, it drives the first connecting member 42, thereby driving the first pressing member 31 to move along the predetermined direction, so as to realize the precise contact or separation of the battery cell 20.

[0046] Combination Figures 1 to 3 As shown, in the embodiment of the present utility model, the driving assembly 40 further includes a second driving member 43 and a second connecting member 44, and the second driving member 43 is connected to the bottom surface of the mounting frame 10 away from the notch of the mounting groove 11;

The second pressing member 32 is connected to the second connecting member 44 and is located on the same side of the second driving member 43. The second driving member 43 drives the second connecting member 44 to drive the second pressing member 32 to move along the second direction so that the second pressing member 32 abuts against or moves away from the battery cell 20.

[0048] In this embodiment, in addition to the first driving member 41 and the first connecting member 42, the driving assembly 40 also includes a second driving member 43 and a second connecting member 44. The second driving member 43 is also connected to the bottom surface of the mounting frame 10 away from the notch of the mounting groove 11, ensuring the stability and accuracy of the battery cell 20 in two directions.

[0049] The second connecting member 44 is disposed on the outer surface of one side of the mounting frame for easy operation. The second driving member 43 passes through the mounting frame and is connected to the second connecting member 44. This connection mode enables the second driving member 43 to directly drive the second connecting member 44. The second pressing member 32 is connected to the second driving member 43 through the second connecting member 44 and is located on the same side of the second driving member 43. When the second driving member 43 is activated, it transmits force to the second connecting member 44, thereby driving the second pressing member 32 to move along the second direction, thereby achieving precise contact or separation with the battery cell 20.

[0050] The moving direction of the second pressing member 32 is perpendicular to that of the first pressing member 31, forming a three-dimensional positioning system, so that batteries of different sizes can be effectively fixed and positioned. By accurately controlling the second driving member 43, the position of the second pressing member 32 can be easily adjusted to meet the needs of batteries of different sizes, thereby greatly improving the automation level and production efficiency of the production line.

[0052] In this embodiment, the second pressing member 32 is composed of a second pressing portion 321 and four second connecting portions 322. The second pressing portion 321 is the portion that directly contacts one side of the battery cell 20, and its arrangement ensures a close fit and stable contact with the battery cell, thereby maintaining the positioning accuracy of the battery cell during the welding process.

[0053] The four second connection parts 322 are evenly distributed on the surface of the second pressing part 321 away from the battery cell 20. They not only provide a stable support for the second pressing member 32 on the mounting frame 10, but also enhance the structural stability and symmetry of the second pressing member 32 through such a spaced arrangement. Each second connection part 322 is inserted into the mounting hole 12 on the mounting frame 10 and connected to the second connection member 44 through a certain connection mechanism.

[0054] The second driving member 43 drives the second pressing member 32 to move along the second direction through the second connecting member 44, so as to achieve accurate contact or separation with the battery cell 20. The arrangement of the four second connecting portions 322 not only provides multi-point support, but also ensures the balance and stability of the second pressing member 32 during movement, thereby improving the accuracy and reliability of battery cell positioning.

[0055] Combination Figures 1 to 3 As shown, in the embodiment of the present invention, the first pressing portion 311 is used to abut against a side surface of the battery cell and is provided with a protective layer 33 , and each second pressing portion 321 is used to abut against a side surface of the battery cell and is provided with a protective layer 33 .

[0056] In this embodiment, the cell positioning device is provided with a protective layer 33 on the surface of the first pressing portion 311 and the second pressing portion 321 in order to provide protection for the cell during welding to ensure the integrity and performance of the cell. The protective layers are particularly arranged on the side of the cell 20 to provide additional protection.

[0057] The main function of the protective layer 33 is to prevent the surface of the battery cell from being damaged or contaminated during the battery cell positioning and welding process. The protective layer 33 can be made of a soft material with good wear resistance, such as rubber, silicone or other synthetic materials, which can effectively absorb the impact force that may be generated by the pressing member when positioning the battery cell, while reducing friction and protecting the surface of the battery cell from scratches or wear.

[0064] In this embodiment, the partition 13 is arranged in the mounting groove 11, effectively dividing a larger mounting groove into two independent parts, each part is used to install a battery cell 20. This arrangement allows the battery cell positioning device to handle two battery cells at the same time, thereby improving production efficiency and processing capacity.

[0065] In order to adapt to the layout of this dual battery cell, the first pressing member 31 and the second pressing member 32 are arranged to appear in pairs.

The mounting hole 12 is opened on the two opposite groove walls of the mounting groove 11 in the second direction, ensuring that the second pressing member 32 can fix the battery cell 20 from both sides.

[0070] The function of each second pressing member 32 is to press and fix the battery cell 20 to a surface of the partition 13.
