Affected by the installation accuracy of the assembly, it is difficult to ensure that each knife on the stacking table is parallel to the battery cells by simply controlling the tolerance of the parts themselves. In the past, the adjustment direction of the stacking knife could only be adjusted along the long and short sides of the horizontal direction of the battery cells, and it could not solve the problem that the knife and the horizontal direction of the battery cells were not parallel, which would cause indentations in the stacked battery cells due to uneven force on the contact surface between the pole piece and the knife.

An adjustment gap is formed between the front and rear protrusions of the limit block, and the adjusting screw is inserted from one protrusion of the limit block and passes through the knife press adjustment stand and comes out from the other protrusion of the limit block. The position of the knife press adjustment stand can be adjusted forward and backward by screwing in and out of the adjusting screw. The linear guide rail is vertically arranged in front of the knife press adjustment stand, the knife press mounting seat is movably arranged on the linear guide rail, the battery cell knife press is arranged on the knife press mounting seat, and the lifting device is arranged at the rear of the knife press adjustment stand to drive the battery cell knife press to move up and down along the linear guide rail.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0016] Example
[0017] See also Figure 1 , Figure 2The present embodiment provides a press knife seat assembly that can quickly adjust the parallelism of the press knife relative to the surface of the laminated battery core, including a press knife adjustment base 1, an adjustment screw 2, a press knife adjustment stand 3, a linear guide 4, a press knife mounting seat 5, a battery core press knife 6 and a cylinder 7. A limit block 8 is provided on one side of the press knife adjustment base 1. Figure 3 , Figure 4 The top of the knife press adjustment base 1 and the limit block 8 is provided with a first arc surface 11, and the bottom of the knife press adjustment stand 3 is provided with a second arc surface 31 adapted to the top of the knife press adjustment base 1 and the limit block 8. The knife press adjustment stand 3 is adjustably arranged on the knife press adjustment base 1 and the limit block 8, and an adjustment interval is formed between the front and rear protrusions of the limit block 8. The adjusting screw 2 penetrates from one protrusion of the limit block 8 and passes through the knife press adjustment stand 3 and exits from the other protrusion of the limit block 8. The two ends of the adjusting screw 2 The end thread is connected with a locking nut 9, and the position of the knife pressing adjustment seat 3 can be adjusted forward and backward by screwing in and out the adjusting screw 2. The linear guide 4 is vertically arranged in front of the knife pressing adjustment seat 3, and the knife pressing mounting seat 5 is movably arranged on the linear guide 4. The battery cell knife pressing 6 is arranged on the knife pressing mounting seat 5. The cylinder body of the cylinder 7 is arranged at the rear of the knife pressing adjustment seat 3, and the cylinder axis of the cylinder 7 faces upward and is connected to the battery cell knife pressing 6. The battery cell knife pressing 6 can be driven to move up and down along the linear guide 4 through the cylinder 7.
[0018] Working principle: The parallelism between the battery cell pressing knife 6 and the surface of the battery cell can be quickly adjusted by adjusting the screw 2. Since the matching surface between the pressing knife adjustment stand 3 and the pressing knife adjustment base 1 is an arc surface, the parallelism between the battery cell pressing knife 6 and the surface of the battery cell can be adjusted by screwing in and out the adjusting screw 2, so that the battery cell pressing knife 6 can perfectly press the battery cell without causing indentations on the battery cell. After the parallelism between the battery cell pressing knife 6 and the surface of the battery cell is adjusted, tighten the locking nuts 9 at both ends of the adjusting screw 2 to prevent the pressing knife adjustment stand 3 and the pressing knife adjustment base 1 from sliding relative to each other during use.
[0019] In summary, the press knife seat assembly has a simple structure, can quickly adjust the parallelism of the press knife relative to the surface of the laminated battery cell, is easy to adjust, and has good economic benefits for debugging and production.
