When the laser sensor 422 detects that the finger-clamping cylinder 312 has not clamped a spring in the predetermined process, the control unit will control the alarm to issue an alarm signal to remind the worker when the finger-clamping cylinder 312 fails to clamp the spring 205 to be picked up.

[0068] The specific working process of the starter carbon brush base plate spring mounting machine in this embodiment is as follows:

[0069] (1) The vibratory plate 201 delivers the springs in an orderly manner to the end of the discharge guide rail of the vibratory plate 201, waiting for the material to be picked up;

[0070] (2) The horizontal picking cylinder 305 drives the horizontal slide plate 307 to move horizontally. After it reaches the position, the vertical starting cylinder drives the vertical slide plate 310 to descend. After it reaches the position, the finger-clamping cylinder 312 closes and clamps the spring 205 to be picked up at the picking notch 204. Then the vertical driving cylinder 309 drives the vertical slide plate 310 to rise. Then the horizontal moving cylinder drives the horizontal slide plate 307 to move. Then the vertical driving cylinder 309 drives the vertical slide plate 310 to descend, so that the finger-clamping cylinder 312 is directly above the spring slot 429 of the spring to be placed. Then the finger-clamping cylinder 312 releases and puts the spring into the spring slot 429 of the spring plate 428. Then the vertical moving cylinder drives the vertical slide plate 310 to rise. The horizontal picking cylinder 305 drives the horizontal slide plate 307 to move horizontally and performs the next spring picking action. Repeat the spring picking 4 times to fill the 4 spring slots 429 of the spring plate 428.

[0071] (3) While the material taking assembly is in operation, the starter carbon brush base plate 1 and cover plate 2 are placed on the base plate fixture 427 by hand. The pressing cylinder 402 presses down, the pressing plate 403 presses the cover plate 2 tightly, and the riveting cylinder 404 drives the stamping rod 406 to extend forward. The stamping rod 406 rivets the riveting pieces on both sides of the cover plate 2 to the starter carbon brush base plate 1.

[0072] (4) The spring assembly and the picking mechanism work as follows: The servo motor 424 drives the spring plate 428 to rotate to a suitable angle. The picking mechanism takes out the spring and puts it into the spring slot 429 of the spring plate 428 until all four spring slots 429 are filled with springs. The laser sensor 422 is used to detect whether the picking mechanism has successfully picked up the spring to prevent missing springs. If the picking is unsuccessful, an alarm is issued and the picking is repeated once. After the spring plate 428 is full, the longitudinal drive cylinder 412 drives the longitudinal slide plate 418 to move backward, and at the same time, the four springs are picked up. The spring compression cylinder 419 compresses the spring to a suitable length. After the longitudinal drive cylinder 412 is in position, the two ejector cylinders 434 rise, driving the four ejector pins 437 to eject the compressed spring from the spring carrier plate 428 and simultaneously insert it into the spring mounting groove 11 of the starter carbon brush base plate 1. After completion, the ejector cylinder 434, spring compression cylinder 419, pressing cylinder 402 and riveting cylinder 404 are simultaneously reset. The longitudinal movement cylinder continues the next round of spring installation. The starter carbon brush base plate 1 is then manually removed after installation.
