[0012] The advantages of the automotive wiper module motor magnetic sheet hot riveting and magnetization device provided by this utility model are as follows: The motor component is placed into a turntable positioning mechanism for positioning. The DD motor rotates 90°, driving the circular turntable to rotate and deliver the motor component to each process step. The photoelectric sensor on the photoelectric fixing rod ensures that the positioning fixture has the product equipment for the next step. The positioning fixture supports and positions the motor housing through the housing positioning block, and supports the reduced housing through the reduced housing support block to prevent the motor from tilting under force. The first and second positioning columns position the four legs of the motor component to ensure consistent positioning. The magnetic sheet is placed into the worm gear hole. The rotary positioning mechanism rotates to deliver the component to the hot riveting mechanism. The lifting positioning mechanism then lifts the positioning fixture. The hot riveting mechanism, driven by a servo cylinder, extends and moves the hot riveting head downwards to rivet the magnetic sheet to meet the riveting requirements. During the process, the servo cylinder's movement monitors the equipment displacement and pressure. The second guide shaft ensures consistent up-and-down movement of the hot riveting head. The temperature controller controls the riveting temperature of the hot riveting head within ±1.5℃. A heat insulation plate prevents heat loss and heating of precision components such as the servo cylinder, which could affect accuracy. The hot riveting mechanism then rivets the magnetic sheet. After riveting, the hot riveting mechanism and the lifting positioning mechanism retract. The rotary positioning mechanism rotates to deliver the motor component... At the magnetization mechanism; the lifting and positioning mechanism lifts the positioning fixture, the magnetization cylinder extends, and pushes the cylinder connecting plate downward through the first cylinder connector. The third guide shaft limits the vertical downward movement of the cylinder connecting plate, causing the magnetization head to contact the magnetic sheet. After the magnetization cylinder reaches its position, magnetization begins. After magnetization is completed, the magnetization cylinder retracts, causing the magnetization head to return to its original position. After magnetization is completed, the magnetization mechanism and the lifting and positioning mechanism retract, and the turntable positioning mechanism rotates, sending the motor components to the missing rivet and magnetization detection mechanism; the CCD camera takes a picture to identify whether the magnetic sheet is missing a rivet. After taking the picture, the large guide rod cylinder extends, causing the cylinder adapter plate and the small guide rod cylinder to extend. After the large guide rod cylinder reaches its position, the small guide rod cylinder extends, driving the magnetic switch to extend as well. The magnetic switch detects whether the magnetic sheet is magnetized. After the detection is complete, the small guide rod cylinder retracts, and after the large guide rod cylinder reaches its position, it retracts. The turntable positioning mechanism transports the motor components to the manual material handling area. The turntable positioning mechanism rotates to remove the parts. The hot riveting equipment uses a turntable structure, allowing for parallel processes and high production efficiency. The crank is riveted first, followed by hot riveting and magnetization of the magnetic sheet, eliminating the quality hazard of nut loosening that can occur with nut locking. At the same time, the hot riveting and magnetization process uses a ball joint for angular positioning, improving product consistency. The equipment has automatic monitoring for missed riveting and missed magnetization to prevent defective products from being shipped out. Attached Figure Description
