Description

TECHNICAL FIELD

[0001] The utility model belongs to workpiece transportation technical field, concretely relates to a part vertical and horizontal conversion device. BACKGROUND

[0002] In modern industrial production, the application of automation technology has become increasingly common, especially in the field of assembly and packaging. In order to improve efficiency and accuracy, every link on the automated assembly line must be carefully designed to ensure smooth process and product safety. In this process, accurate vertical and horizontal posture adjustment of ammunition and its packaging is a crucial step. This adjustment not only concerns the smooth operation of the assembly line, but also directly affects the quality and safety of the final product.

[0003] However, under the existing technical conditions, this key step - the vertical and horizontal conversion of the packaging cylinder and the bullet body - still needs to rely on manual operation. This manual operation, although to some extent guarantees flexibility, also brings many problems. First of all, since the bullet may accidentally fall when it is taken out of the packaging cylinder, this not only poses a direct threat to the safety of the operator, but also may cause them to suffer serious physical injury. Secondly, the falling of the bullet may also cause more serious consequences, such as explosion, which not only endangers the safety of the operator, but also may cause damage to the entire production environment.

[0004] In addition, the efficiency and consistency of manual operation are often difficult to guarantee, which is particularly evident in high-speed automated production lines. The instability of manual operation may cause fluctuations in production efficiency, and even may affect the production rhythm of the entire assembly line. Therefore, although the manual conversion link is still retained in the current production process, its potential risks and efficiency problems have attracted widespread attention in the industry. In order to ensure production safety and improve production efficiency, it is particularly urgent to develop an automated device that can replace manual vertical and horizontal conversion.
