Description

Technical Field

[0001] The utility model relates to the technical field of chemical composition and storage, and in particular to a high-stability chemical composition and storage device. Background Art

[0002] In the field of soft package chemical composition and filling, in the chemical composition and filling process, the structure generally adopted by the existing horizontal equipment is: linear bearings or ball screws are used to connect the large plate at the pressurizing end and the large plate at the pressure-receiving end, and the parallelism of the middle layer plate is indirectly controlled by ensuring the parallelism between the two large plates.

[0003] Due to the influence of factors such as the processing error of the large plate and the assembly error, the parallelism between the pressure plate and the pressure plate is not ideal after the mechanism is assembled. Due to the limitations of linear bearings and ball screws, as well as the complex structure and limited maintenance space, it is very difficult to adjust the parallelism between the pressure plate and the pressure plate after assembly. In addition, due to the difference in actual temperature on both sides of the battery cell during the processing, uneven heating will occur, affecting the yield rate. Utility Model Content

[0020] like Figure 1 to Figure 2 As shown, the utility model discloses a high stability capacity dividing device, including a clamping assembly 1 for clamping a battery cell. The structure of the clamping assembly 1 is prior art, such as disclosed in Patent No. CN 217943122 U, etc. The utility model will not be elaborated here, and all of them belong to the protection scope of the utility model.

[0021] A clamping block 2 is provided on one side of the clamping assembly 1, and a driving plate 3 is provided on the side of the clamping block 2 away from the clamping assembly 1.

In addition, the structure is reasonably arranged, compact, reduces the occupied space, and has a wide applicability.
