Description

Technical Field

[0001] The utility model relates to the field of deviation rectifying and positioning mechanisms, in particular to the field of lithium battery pole piece winding, and specifically to a pole piece feeding deviation rectifying and positioning mechanism. Background Art

[0002] Lithium-ion batteries are a new generation of green high-energy batteries with excellent performance and have become one of the key points in the development of high-tech. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, pollution-free, small size, small internal resistance, less self-discharge, and many cycle times. Due to the above characteristics, lithium-ion batteries have a wide range of applications, including but not limited to many civilian and military fields such as mobile phones, laptops, and tablets. In recent years, the lithium-ion battery manufacturing industry has developed rapidly, and the requirements for the process quality of manufacturing battery cores have been continuously improved. The accurate feeding and high-precision winding of pole pieces during the production process play an important role in ensuring consistent battery performance and stable quality.

[0003] During the manufacturing process of battery core pole pieces, the deviation rectifying and positioning mechanism is a key device to ensure the accurate position of pole pieces during transportation and processing. The existing transportation of battery core pole pieces is generally the transportation of wound battery core pole pieces, and the existing battery core pole pieces are also provided with cutting the wound battery core pole pieces into corresponding-sized pole pieces for convenient subsequent winding use. Therefore, for the transportation process of pole pieces, a deviation rectifying and positioning mechanism is usually required to rectify the pole pieces, thereby improving the accuracy and stability of subsequent winding processing.

[0004] However, the existing pole piece feeding deviation rectifying and positioning mechanism still has the following defects. First, the transportation and positioning structure during the transportation process of cutting the pole pieces into corresponding sizes is relatively simple, which is not conducive to the accurate feeding and positioning of pole pieces and affects the stability and reliability of the subsequent processing of pole pieces. Second, the existing pole pieces of different specifications and materials may show different characteristics during transportation. The existing deviation rectifying mechanisms are often difficult to quickly adapt to these changes, resulting in unsatisfactory deviation rectifying effects, and the deviation rectifying accuracy in the detection and control process of the deviation rectifying mechanism is poor, resulting in deviations still existing during the transportation of pole pieces and affecting the quality of subsequent processing.

The electrode feeding deviation correction and positioning mechanism according to claim 4 is characterized in that: The rotation correction drive assembly includes a second drive motor, a second support seat, a second support block and a second screw rod. The second support seat and the second support block are installed on the movable plate. The second screw rod is installed between the second support seat and the second support block. One end of the second screw rod passes through the second support seat and is connected to the drive shaft of the second drive motor through a second connecting piece. The second screw rod is connected to the linkage block through a second nut, so that the linkage block can be driven to drive the connecting rod to make a linear motion, and the correction mounting seat can drive the correction workbench to swing through the first joint bearing.

6. The electrode feeding deviation correction and positioning mechanism according to claim 1 is characterized in that: A moving component is connected to the bottom plate, and the moving end of the moving component extends toward the edge of the correction workbench, and a pushing plate for installing a correction detection device is arranged on the moving component, and a driving source that can drive the pushing plate to move along the moving component toward the correction workbench is connected to the side of the pushing plate. The correction detection device includes two correction sensors and two sensing amplifiers, and the two correction sensors are installed at both ends of the pushing plate through corresponding mounting brackets, and the sensing ends of the two correction sensors extend toward the edge of the correction workbench. The two sensing amplifiers are both installed on the pushing plate and are electrically connected to the corresponding two correction sensors. The driving source can drive the correction sensor to move toward the edge of the workbench by driving the pushing plate, so that the pole piece on the correction workbench can be detected in real time through the sensing end of the correction sensor.

7. The electrode feeding deviation correction and positioning mechanism according to claim 6 is characterized in that: Both ends of the push plate are connected to a lifting cylinder, the telescopic end of the lifting cylinder extends toward the top of the correction workbench, and the telescopic end of the lifting cylinder is connected to a pressure plate, which can be driven by the telescopic end of the lifting cylinder to move the pressure plate toward the upper surface of the correction workbench, thereby pressing and positioning the pole piece on the correction workbench.

8. The electrode feeding deviation correction and positioning mechanism according to claim 1 is characterized in that: The correction detection device includes a detection camera and an auxiliary light source. The detection camera is arranged above the correction workbench, and the detection end of the detection camera extends toward the upper surface of the correction workbench. The auxiliary light source is installed on the movable plate, and the light source end of the auxiliary light source extends toward the correction workbench.
