SCREWING MACHINE AND TROUBLE SHOOTING METHOD THEREOF

摘要

The disclosure provides a screwing machine including a machine frame, a screwing device, a suction device, a negative pressure judgment device, and a screw removal device. The screwing device is moveably located on the machine frame. The screwing device has a nozzle, and the screwing device is configured to fasten a screw into a workpiece. The suction device has a connecting tube communicated with the nozzle of the screwing device. When the suction device sucks the screw, the suction device drains an air inside the nozzle to enable a negative pressure inside the nozzle. Further, the negative pressure judgment device is communicated with the air inside the nozzle.

主权项

1. A screwing machine, comprising:
a machine frame; a screwing device moveably located on the machine frame, the screwing device having a nozzle, and the screwing device being configured to fasten a screw into a workpiece; a suction device having a connecting tube communicated with the nozzle of the screwing device, wherein when the suction device sucks the screw, the suction device drains an air inside the nozzle to enable a negative pressure inside the nozzle; a negative pressure judgment device communicated with the air inside the nozzle, wherein when the nozzle sucks the screw, the negative pressure judgment device determines whether a pressure value of the air inside the nozzle matches a default value; and when the negative pressure judgment device determines that the air inside the nozzle matches the default value, the screwing device fastens the screw into the workpiece; and a screw removal device comprising an accommodation space, an opening, and a resilient stopper located at the opening, wherein when the negative pressure judgment device determines that the air inside the nozzle does not match the default value, the screwing device moves to the screw removal device and makes the nozzle be aligned with and contact the resilient stopper, such that the resilient stopper removes the screw from the nozzle to make the screw drop into the accommodation space through the opening.
