[0002] In the automotive manufacturing industry, most production lines still employ a combination of manual and automated production methods. Due to factors such as working height or production line layout, certain parts inevitably require manual operation on platforms during the production process. For areas on the production line where manual operation requires significant height and a large operating range, there is an urgent need to develop a retractable platform.

[0003] The pre-assembly line assembly and inspection process involves assembling and processing multiple systems, implementing complex technological flows, and demanding high technical skills and strict quality control. This step platform is suitable for operation on the pre-assembly line of an automotive production line. The main task of the pre-assembly line is to assemble and process automotive components, covering multiple parts such as the suspension system, steering system, transmission system, and braking system. On the pre-assembly line, various processes such as assembly, welding, gluing, and testing of parts are carried out to ensure the overall structural strength, functionality, and safety of the vehicle.

[0004] The platform mechanism allows workers to access different work positions to operate automotive parts. In addition, because it is above the ground, it not only facilitates operation but also provides insulation from the ground and prevents static electricity. Summary of the Invention

[0005] The purpose of this invention is to provide a follow-up step mechanism for automotive pre-assembly lines, which can solve the problem of manual operation at high heights and with large operating ranges on the production line, and improve production efficiency.

[0017] This utility model discloses a retractable workstation platform. In actual use, the drive motor operates, allowing for reciprocating movement along the Y-axis to adjust the Y-position of the retractable pedal. Simultaneously, when the retractable pedal is in use, the drive cylinder operates, causing the piston rod of the cylinder to reciprocate, which in turn drives the reciprocating movement between the guide rail and the retractable pedal, achieving the X-axis extension and retraction function of the platform. Thus, this utility model achieves position control and change in the XY directions, facilitating manual operations and production line layout, reducing the workload of workers, ensuring production safety, and improving production efficiency.
