[0064] The sub-component is placed on the feeding block 4011. Under normal conditions, due to the elastic force of the spring, the clamping block 4012 abuts tightly against the feeding block 4011, and the sub-component is fastened on the feeding block 4011. When it is necessary to pick up or place the material, the opening and closing driving cylinder 4021 drives the pushing block 4022 to move backward. The pushing block 4022 pulls the clamping block 4012 backward, and the clamping block 4012 is separated from the feeding block 4011 by a certain distance, which is convenient for picking up and placing the sub-component.

The vertical movement driving device 813 includes a vertical movement driving cylinder 8131 and a vertical movement slider 8132.

The stop piece vertically moves through the U-shaped groove along with the first abutting rod 8231. The first displacement sensor 8232 determines whether the small component has been press-fitted according to the vertical position of the first abutting rod 8231. When the press-fitting is in place and not in place, the height of the small component in the gearbox of the motor is different. The lower end of the second abutting rod 8241 abuts against the small component, and the upper end of the second abutting rod 8241 abuts against the second displacement sensor 8242. The second displacement sensor 8242 determines whether the small component is press-fitted in place according to the height position of the second abutting rod 8241. The second abutting rod 8241 is slidably sleeved outside the first abutting rod 8231, so that the first detection device and the second detection device simultaneously detect whether the press-fitting is performed and whether the press-fitting is in place, avoiding position interference during detection, improving the detection efficiency, with a compact overall structure and less occupied area.
