Description

Technical Field

[0001] This invention relates to the field of mechanical technology, specifically to an online automatic integration and assembly machine for automotive brake base plate components. Background Technology

[0002] The brake backplate assembly, mainly composed of the brake backplate, shoe pin, and flexible cylindrical pin, is a key component of the automotive braking system. Located at the bottom of the braking system, it is typically made of metal and connects the brake components to the wheels. The primary function of the brake backplate assembly is to transmit braking force and withstand the pressure generated by that force, thereby enabling the vehicle to brake. Currently, only semi-automatic assembly equipment is available for assembling the brake backplate assembly; assembly primarily relies on a combination of machines and manual labor. For example, Chinese invention patent CN103769848A discloses "an assembly system for automotive pedal pins." This assembly process still carries certain risks and typically requires extensive manual operation and skilled assembly techniques. Manual hammering during assembly results in uneven force distribution, poor assembly quality, low precision, and compromised quality, leading to high customer claims. Furthermore, the hammering process is physically demanding, causing significant noise pollution and frequent arm injuries to workers, negatively impacting their physical and mental health and the surrounding environment. Because this assembly method is purely manual, the assembly quality is closely related to the worker's physical strength and mood, thus having a significant impact on assembly quality and production efficiency.
