With the development of lithium battery packaging technology, battery cap packaging machines have emerged.

One side of the four movable blocks is fixedly connected to the same concave plate, and two groups of fixed arc plates are fixedly connected to the inside of the concave plate. Both sides of the inner wall are movably connected with the same bidirectional threaded rod through a shaft sleeve. The multi-purpose cylindrical lithium battery capping and packaging machine rotates the fixed block, which drives the bidirectional threaded rod to rotate. The movable bar moves along the bidirectional threaded rod, and the movable bar drives the movable arc plate to move, thereby realizing the movable arc plate and the fixed arc plate to clamp the lithium battery.

[0036] like Figure 1 and Figure 2 As shown, it is a positioning device 100 shown in the present invention, which is used to position cylindrical batteries.

This method of clamping the cylindrical battery is beneficial when clamping cylindrical batteries of different sizes.

[0038] Below, combined Figures 1 to 6 , the above-mentioned positioning device 100 is further explained.

[0039] like Figure 1 As shown, the interior of the fixing frame 10 is used to install the rotating seat 20, and the end surface of the fixing frame 10 is used to place the cylindrical battery.

[0040] like Figure 3 As shown, there are four clamping mechanisms 30, which are arranged around the rotating seat 20. Each clamping mechanism 30 includes a clamping member 31, a guide assembly 32 and a connecting rod 33. The clamping member 31 is installed on the guiding assembly 32. The guiding assembly 32 is slidably connected to the fixed frame 10 and approaches or moves away from the rotating seat 20 along the fixed frame 10. One end of the connecting rod 33 is rotatably connected to the guiding assembly 32, and the other end of the connecting rod 33 is rotatably connected to the rotating seat 20. The clamping member 31 includes a fixed shaft and a rotating roller rotatably connected to the fixed shaft. The fixed shaft is connected to the guiding assembly 32. The fixed shaft of the clamping member 31 is connected to the guiding assembly 32, and the rotating roller of the clamping member 31 is rotatably connected to the fixed shaft. This is beneficial for the clamping member 31 to push the cylindrical battery in the process of pushing the cylindrical battery. The cylindrical battery is pushed to rotate in the direction of the rotating axis 21 of the rotating seat 20 by the rolling rotating roller, so as to avoid the clamping member 31 from clamping the cylindrical battery, thereby achieving the purpose of improving the clamping stability of the cylindrical battery.

[0041] like Figure 3 , Figure 5 and Figure 6 As shown, the guide assembly 32 includes a guide rail 321, a slider 322, a connecting block 323 and an adapter block 324, the guide rail 321 is installed on the fixing frame 10, the slider 322 slides along the guide rail 321 to approach or move away from the rotating seat 20, the connecting block 323 is installed on the slider 322 and is rotatably connected to the connecting rod 33, the adapter block 324 is installed on the connecting block 323 and is connected to the clamping member 31, wherein the number of the guide rails 321 and the slider 322 are both two, and each guide rail 321 and the slider 322 are arranged one by one on the rotating seat 20. On both sides of the connecting block 324, the adapter block 324 is provided with a plurality of mounting holes 325, each mounting hole 325 is arranged along the sliding direction of the adapter block 324, and the fixed axis of the clamping member 31 is connected to one of the mounting holes 325. The method of setting a plurality of mounting holes 325 for mounting the clamping member 31 on the adapter block 324 along the sliding direction of the adapter block 324 is adopted, which is beneficial to adjust the distance between each clamping member 31 and the rotating axis 21 line of the rotating seat 20, so as to adapt to cylindrical batteries of different sizes and improve the clamping range of the positioning device 100.

[0042] like Figure 2 As shown, the driving mechanism 40 includes a driving member 41, a synchronous wheel 42 and a synchronous belt. The driving member 41 is installed in the fixed frame 10. There are multiple synchronous wheels 42. Each synchronous wheel 42 is connected to the rotating seat 20 and the driving member 41 one by one. The synchronous belt transmission connects each synchronous wheel 42. There are multiple rotating seats 20, and the number of clamping mechanisms 30 is set corresponding to the number of rotating seats 20.

[0043] The working principle of the positioning device 100 provided in the present application is as follows: the cylindrical battery is placed between the clamping members 31 of each clamping mechanism 30, and the driving member 41 of the driving mechanism 40 drives each rotating seat 20 to rotate using the synchronous wheel 42. The rotating rotating seat 20 pulls the guide assembly 32 to slide along the fixed frame 10 through the connecting rod 33, and drives each clamping member 31 to approach each other to clamp the cylindrical battery. When the cylindrical battery is processed, the driving member 41 controls each rotating seat 20 to rotate in the opposite direction, and uses the connecting rod 33 to push the guide assembly 32 to slide along the fixed frame 10, and drives each clamping member 31 to move away from each other to release the cylindrical battery, thereby achieving the clamping and release of the cylindrical battery.

[0044] The positioning device 100 provided in the present application has the following beneficial effects: 1. The driving mechanism 40 is used to control the rotation of the rotating seat 20, so that the guide assembly 32 is pulled to slide along the fixed frame 10 through each connecting rod 33, and each clamping member 31 is driven to approach the rotating axis 21 line close to the rotating seat 20 at the same time. When clamping cylindrical batteries of different sizes, the center position of different cylindrical batteries can still be ensured to remain unchanged, thereby avoiding readjusting the position of pressing the cylindrical battery, thereby achieving the purpose of improving the debugging efficiency of the battery cap packaging machine.

[0045] 2. A plurality of mounting holes 325 for mounting the clamping members 31 are provided on the adapter block 324 along the sliding direction of the adapter block 324, so as to facilitate adjusting the distance between each clamping member 31 and the rotation axis 21 line of the rotating seat 20, thereby adapting to cylindrical batteries of different sizes and improving the clamping range of the positioning device 100.

[0046] 3. The fixed axis of the clamping member 31 is connected to the mounting hole 325, and the rotating roller of the clamping member 31 is rotatably connected to the fixed axis. This facilitates the clamping member 31 to push the cylindrical battery. The cylindrical battery is pushed to rotate in the direction of the rotating axis 21 of the rotating seat 20 by the rolling rotating roller, thereby avoiding the clamping member 31 from clamping the cylindrical battery, thereby achieving the purpose of improving the clamping stability of the cylindrical battery.

[0047] A battery cap packaging machine comprises any one of the positioning devices 100 described above. The battery cap packaging machine provided by the present application has the beneficial effect that by adopting the positioning device 100 described above, it is helpful to reduce the time for adjusting the pressing position of the cylindrical battery, so as to achieve the purpose of improving the debugging efficiency of the battery cap packaging machine.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
