Traditional car factories can no longer meet the demands of modern society, and manufacturers are striving to accelerate product upgrades and transform into intelligent factories to seize market share. Traditional transmission systems have the following drawbacks: low transmission precision, short service life, high production costs, the need for manual intervention in production, and slow worker operation time. Therefore, solving the problems of low production precision, reducing production costs, semi-automatic production, and low efficiency, and moving towards precise, intelligent, and efficient factories, has become an urgent technical challenge that needs to be addressed. Summary of the Invention

The horizontal guide mechanism includes a slide rail and four sliders. The slide rail is connected to four sliders, and the sliders are connected to a support base to slide in the same direction as the slide rail, thus improving structural lifespan and reducing wear. One side of the support base is fixed to a rack, which engages with a gear to achieve rack-and-gear engagement. The gear is connected to a servo motor.
