No manual operation is required throughout the process, and the assembly efficiency is high. In addition, the grease used for each worm gear 6 is quantitative, which is convenient for mass production of wiper motors.

Specifically, the worm gear 6 is first manually placed on the material plate 7, and then the material plate 7 is placed on the material cart 5. The material plate 7 is connected to the material cart 5 in such a way that a plurality of positioning protrusions 24 are arranged above the material cart 5 body, and a groove matching the corresponding positioning protrusions 24 is arranged at the bottom end of the lowest material plate 7, so as to connect, and then the material plates 7 are stacked on the material plates 7. The material plates 7 are connected to the material plates 7 in such a way that a mounting groove 21 is arranged above the material plates 7, and a connecting rod 22 is arranged at the bottom end of the material plates 7. The connecting rod 22 of the upper material plate 7 is inserted into the mounting groove 21 of the lower material plate 7, so that the material plates 7 can be stacked. The above steps are repeated to complete the stacking of a plurality of mounting plates 15. The material cart 5 has a large storage capacity, which is convenient for long-term assembly.

The lifting plates 18 are controlled to rise by the cylinder to transport the material to a specified height. The pulling plate 19 can be moved horizontally by the cylinder. The pulling plate 19 has a card block 23 that matches the mounting groove 21. The card block 23 is inserted into the mounting groove 21, and then the top material plate 7 is driven to move horizontally to another group of lifting plates 18. One group of lifting plates 18 rises to make the material plate 7 equipped with the worm gear 6 rise for easy clamping, and the other group of lifting plates 18 descends to make the idle material plate 7 descend for easy storage.

[0051] The installation steps in the assembly equipment of the wiper motor transmission assembly provided in this embodiment are as follows: first, start the robot arm 13, move the worm gear 6 on the material plate 7 to the grease injection platform 8, and then the detection sensor 12 senses that the worm gear 6 is placed in, control the quantitative grease injection valve 10 to start, and grease the worm gear 6 through the grease injection block 9.
