Description

Technical Field

[0001] The invention relates to the technical field of novel windshield wiper production, and in particular to a rubber strip spoiler strip connecting block assembly machine and automatic assembly equipment for windshield wipers. Background Art

[0002] Windshield wipers, also known as windshield wipers, are generally installed on the front and rear windshields of a car. Their main function is to clean dust, dirt and raindrops thereon to ensure the visibility of the glass during driving, thereby ensuring safety when driving a car.

[0003] When assembling the rubber spoiler strip connecting block of the wiper, the existing connecting block is usually pre-processed with a mounting hole. If the mounting hole deviates from the highest point of the steel sheet, it means that the interface seat cannot exert force on the highest point of the steel sheet, which makes it easy for the two ends of the steel sheet to be subjected to uneven force during the use of the wiper, resulting in instability of the steel sheet structure, which in turn affects the friction effect of the rubber strip on the glass, and even destroys the overall stability of the wiper, affecting the use effect of the wiper.

[0004] Therefore, how to provide a spoiler strip connection block assembly machine with better assembly effect and improve the overall production quality and efficiency of wipers is a technical problem that needs to be solved urgently in this field. Summary of the invention

After the punching is completed, the cutter cylinder drives the cutter backward. After the rubber strip servo mechanism clamps the rubber strip, the clamping drive pushes the rubber strip pressing block upward to release the rubber strip. At the same time, the material stopper cylinder drives the rubber strip sensing block upward. After the rubber strip is dragged to the right by the rubber strip servo mechanism, the material stopper cylinder drives the rubber strip sensing block downward to return to its position.
