[0037] Working Principle: This utility model consists of a belt mechanism 1, a motor-carrying tray 2, a worm gear feeding mechanism 3, a worm gear clamping and assembly mechanism 4, a cap positioning and rotating mechanism 5, a cap gluing mechanism 6, a cap clamping and pre-assembly mechanism 7, a motor laser marking mechanism 8, a cap pressing mechanism 9, a spring-loaded automatic assembly mechanism 10, an equipment frame 11, a worm gear shaft pressing elastic retaining ring mechanism 12, an oil injection, photographic detection and rejection mechanism 13, an energized oil injection mechanism 14, a lifting and positioning mechanism 15, and an electrical control system. The motor-carrying tray 2 provides the mechanism for the motor to move on the production line. This motor-carrying tray 2 moves and circulates repeatedly on the belt mechanism 1. The worm gear structure includes a worm gear body 110, on which an upper shaft 19 and a lower shaft 11 are mounted. 1. An O-ring 16, a flat washer 17, and an elastic retaining ring body 18 are fitted onto the lower shaft 111. When using this utility model for automatic assembly of the worm gear and cover assembly of an automotive wiper motor, the motor transport tray 2 enters from the upper station and is positioned at the worm gear assembly mechanism. It is then lifted and positioned by the lifting and positioning mechanism 15, awaiting assembly. The worm gear and the valve washer are then manually installed and fed into place by the worm gear feeding mechanism 3, and oil is injected into the worm gear. The worm gear clamping and assembly mechanism 4 clamps and rotates the worm gear to inject oil into the lower shaft 111 of the worm gear for one revolution before moving it to the top of the motor. At the same time, a camera takes pictures to check whether the valve washer is missing and whether the oil injection effect is up to standard. Then, it is installed downwards into the motor housing. If it is not up to standard, an alarm is triggered. After the worm gear is installed, the motor transport tray 2 moves to the energized injection position. The oiling mechanism 14 is lifted and positioned by the lifting and positioning mechanism 15. Then, the motor is powered on to rotate, and oil is injected into the worm gear and the upper surface of the worm gear slide. After the motor-carrying pallet 2 is oiled, it moves to the oiling photo inspection and rejection mechanism 13, and is lifted and positioned by the lifting and positioning mechanism 15. At the same time, the oiling effect is photographed and inspected. If the oiling effect is not qualified, it is rejected by the oiling photo inspection and rejection mechanism 13 and sent to the off-line for centralized processing. If the effect meets the requirements, it continues to move forward to the next station. After the oiling photo inspection, the motor-carrying pallet 2 moves to the pressing elastic retaining ring station. At this time, the worm gear shaft pressing elastic retaining ring mechanism 12 completes the pressing of the elastic retaining ring. The elastic retaining ring has been pre-positioned on the rotating mechanism by manual operation and is automatically placed into the pressing spring by the robot arm. After the elastic retaining ring assembly is pressed onto the positioning shaft, the motor transport tray 2 continues to move to the pre-installed cap station, where it is lifted and positioned by the lifting and positioning mechanism 15. Simultaneously, a six-axis robot pre-installs the cap, pre-applied with adhesive, onto the motor. Manually, the cap is placed on the cap positioning and rotating mechanism 5, and a four-axis robot drives the cap adhesive application mechanism 6 to apply adhesive. The adhesive application effect is then photographed and inspected. This part of the process is parallel to the motor assembly. The motor transport tray 2 moves to the cap pressing mechanism 9, where it is lifted and positioned by the lifting and positioning mechanism 15. The cap pressing mechanism 9 then moves downwards to complete the cap pressing. The motor transport tray 2 continues to move to the motor laser marking mechanism 8, where it is lifted and positioned by the lifting and positioning mechanism 15 to complete the laser marking.Finally, the motor carries pallet 2 into the next device.
