Description

Technical Field

[0001] The present invention relates to the field of practical battery production technology, and more specifically, to a mechanism for flipping and transporting square battery shells. Background Art

[0002] With the rapid development of new energy vehicles and energy storage systems, the demand for lithium batteries is increasing. In the production process of lithium batteries, the battery casing is one of the key components, and the level of automation in its production process directly affects the quality and production efficiency of the product. The traditional battery casing flipping and transport process mainly relies on manual operation or semi-automatic equipment, which has the following problems:

[0003] High labor costs: Manual operations require a lot of manpower input, especially in large-scale production lines. Human resource costs become a major burden for enterprises.

[0004] Low work efficiency: Manual operation is slow and prone to operational errors, resulting in low production efficiency.

[0005] Unstable product quality: Manual operation makes it difficult to ensure the consistency of each flipping and transportation, which can easily cause surface damage to the battery shell and affect product quality.

[0006] Poor safety: During manual operations, workers may face certain safety risks, especially when handling heavy or high-temperature materials.

[0007] To improve the production efficiency and quality of square battery cases and reduce production costs, automated flipping and transfer equipment is becoming an industry trend. While existing automated equipment can achieve some of these functions, it still has limitations in flexibility, precision, and reliability. For example, some devices can only perform simple flipping movements and cannot precisely control the flipping angle and position. Others have complex structures, high maintenance costs, and poor adaptability, making them inflexible and unable to handle different battery case specifications.

[0008] Therefore, developing an efficient, accurate, and reliable battery case flipping and transporting mechanism can not only significantly improve production efficiency and product quality, but also effectively reduce production costs, which has important practical application value. This application provides a battery case flipping and transporting mechanism, which aims to solve the above problems and realize the automated flipping and transport of battery cases.

[0012] Furthermore, the lifting and clamping assembly includes a blocking rod installed in the middle of a support frame, a proximity sensor is installed in the middle of the blocking rod, and two clamping blocks are installed at the left and right ends of the inner side of the support frame. The two clamping blocks can clamp and release the incoming battery square shell. The clamping blocks are located at the rear end of the blocking rod. The two clamping blocks are controlled by a first clamping cylinder, and the two sides of the first clamping cylinder are respectively connected to the lifting cylinder.

[0013] Furthermore, the rear ends of the two clamping blocks are respectively fixedly connected to a clamping jaw adjustment block, and one end of the two clamping jaw adjustment blocks is respectively fixedly connected to a clamping jaw seat, the clamping jaw seat and the clamping jaw adjustment block are perpendicular to each other, and the inner ends of the two clamping jaw seats are respectively connected to the two ends of the first clamping jaw cylinder, and the first clamping jaw cylinder is installed on the clamping jaw cylinder mounting plate, and the clamping jaw cylinder mounting plate is fixed to the rear end of the support frame.

[0017] Furthermore, the translation assembly includes a translation cylinder seat, a translation telescopic cylinder, a cylinder connecting seat, a second clamping cylinder, a translation clamping seat, a translation clamping adjustment block, a fixed plate, a positioning side plate, a blowing bracket, a hollow screw, a material blocking cylinder fixed seat, a second material blocking cylinder seat, a material blocking block, and a material blocking cylinder.
