Abstract

A screw locking control system includes a host, a control unit controlled by the host, an electric screw driver and a holder. The control unit includes a processor, a voltage detecting module, a power outlet for providing electricity to the electric screw driver, and a lighting signal control module electrically connected to a plurality of indicator lamps of the holder. As a result, the control unit can turn on the indicator lamps sequentially via the light signal control module, guiding operators to carry out each screw locking operation and detecting a voltage variance of the electric screw driver to determine whether each screw locking operation is qualified. Thus, the quality of the manufacturing process is consistently maintained.

Claims

1. An operating method for a screw locking control system, the screw locking control system comprising a host, a control unit, an electric screw driver and a holder, the control unit having a processor, a voltage detecting module, a power outlet electrically connected to the voltage detecting module, and a lighting signal control module, the processor being controlled by the host and electrically connected to the host, the voltage detecting module, and the lighting signal control module, the electric screw driver electrically connected to the power outlet, the holder having a plurality of indicator lamps electrically connected to the lighting signal control module, the holder being capable of mounting a product which is to be screw locked, the plurality of indicator lamps corresponding to each screw hole of the product to be screw locked, the indicator lamps being controlled and turned on sequentially by the lighting signal control module, the operating system comprising the steps of:

a) the host transmitting a setting data of each screw locking operation to the control unit;

b) the control unit sequentially turning on the indicator lamps according to the setting data via the lighting signal control module and the electric screw driver sequentially performing each screw locking operation, the voltage detecting module detecting a voltage variance of the electric screw driver in each screw locking operation to determine whether each screw locking operation is qualified; and

c) the control unit transmitting the results of each screw locking operation to the host and displaying the results,

wherein step a) further comprises an initial data setting operation, which comprises setting a locking order first, performing each screw locking operation according to the locking order, and sending the results of each voltage variance to the host to define a preset screw locking time interval of each screw, and

wherein in step b) the voltage detecting module detects the voltage variance of the electric screw driver when the electric screw driver is turned on and turned off to define an actual screw locking time interval;

the host compares the actual screw locking time interval and the preset screw locking time interval to determine whether each screw locking operation is qualified.

2. The operating method as claimed in claim 1, wherein in step b) using a preset tolerance time;

if a time difference between the actual screw locking time interval and the preset screw locking time interval is less than the preset tolerance time, the result of the screw locking operation is passed, otherwise the result of the screw locking operation is failed.

3. The operating method as claimed in claim 1, further comprises step d):

the host determining whether end the screw locking operation;

if the result is false, return to step b), otherwise end the screw locking operation.
