How to operate the reservation / cancellation of the turntable process

The present invention relates to a spot welding robot system, in particular, by using the reservation / cancel pushbutton switch during the turn-table process to improve the work efficiency by eliminating hazards without the operator entering the work area A method of reserving / canceling a turntable process.

1 is a signal flow diagram of a conventional turntable process, the operation preparation switch is turned on (ON), the panel loading is completed on the jig (JIG) A, the cycle start is turned on (ON) and the turntable is moved in reverse rotation (S1) (S4) (S4) (S5), when the turntable is moved to a working position, the robot is working and when the robot finishes the work of JIG A, the panel loading is completed on JIG B (S4) (S5). After that, the cycle start is turned on, and the turntable moves forward to settle in the working position, and the robot performs the work and returns to the initial mode after completing the operation (S6-S8).

In the related art, a panel is loaded on a turntable to be seated at a work position, and the emergency stop switch is turned on until the robot works to stop the turntable and unload the panel.

In addition, since the panel is loaded after the panel is loaded on the jig of the turntable, it cannot be returned, and when an error occurs after loading the panel, the worker enters the work area and unloads the panel manually. It must be (UNLOADING).

As described above, in the conventional turntable process, the panel is not returned by turning after loading the jig of the turntable, and when an abnormality occurs, the operator has to enter the work area and unload the panel manually. there was.

Accordingly, an object of the present invention is to return immediately after the turntable is turned by using the reservation / cancel pushbutton switch, and in the event of an abnormality, the operator unloads the panel without entering the work area to remove the risk factor. The above problem is solved.

As a specific means of the present invention for achieving the above object,

Operation ready switch is turned ON, panel loading is completed in JIG A, cycle start is turned on, and turntable is rotated in reverse direction.After that, turntable stops and returns when load is canceled. LOAD) to solve the problem, and when the canceling switch is OFF (turned off), the turntable is seated in the working position, the robot is working and the panel is loaded on jig B as the robot finishes the work of jig A And after the cycle start is turned on and the turntable is moved to the forward rotation and the reservation cancel switch is turned off, the robot stops at the turntable working position, terminates the robot and returns to the initial mode after canceling the reservation. When the switch is on, the turntable stops and returns to the load position to resolve the problem, then cycle start on By returning to mode.

Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

Figure 2 is a schematic diagram of the spot welding robot system of the present invention, the operator loads on jig A or jig B in the loading position, as shown here, the robot is operated when the tentable moves to reach the working position by operating the turntable When the robot starts work, the robot is started again when the robot reaches the working position after moving the turntable after the panel loading is completed in the panelless jig after completing the robot operation.

3 is a schematic diagram of a control panel of a spot welding robot system according to the present invention. As shown in the drawing, a panel is loaded on a jig in a cycle start switch and the operation is started when the cycle start is turned on after the operation preparation is completed. If the panel is loaded in the jig and the operation ready switch is turned ON, the robot prepares for the operation.When the cycle start is ON, the turntable moves to start the operation. It also has a weak function of robot operation, and when the operation preparation (reservation) switch and cycle start switch are turned on in the reservation cancellation switch and the panel or other problem occurs when the turntable is moved, the reservation cancellation is turned on. The turntable stops and the turntable returns to the loading position.The turntable, robot, etc. If a sudden problem on (ON) event of an emergency stop the operation of the entire process will stop.

FIG. 4 is a sequence diagram of the spot welding robot system of the present invention. As shown in FIG. 4, when PB2 (cycle start) is turned on, CR2 (MAIN RELAY) is turned on and self-maintained, and thus the turntable is moved. Work is started, and when PB1 (cancel reservation) is ON, CR1 is ON and self-maintained because CR2 is self-sustained. In addition, when CR1 is ON, As CR3 is turned on, CR83 and CE84 are turned off as the CR3 is turned on, and the turntable stops. TM1 is turned on one second after the CR3 is turned on. As the TM1 is turned on, the CR4 is turned on and self-maintained.

As the CR4 is turned on, the CR84 is turned on again and the turntable returns to the loading position, and at the same time, the CR4 is turned off when the CR85 is turned on. Is turned off, so the turntable arrives at the loading position and stops.

Figure 5 is a signal flow diagram of the reservation / cancellation operation method of the turn-table process of the present invention, the operation ready switch is turned on (ON), the panel loading to the jig (A) is completed and cycle start is turned on (ON) And the turntable is rotated in the reverse direction (S1-S3), and when the reservation cancel switch is turned on (ON), the turntable stops and returns to the LOAD position to solve the problem (S4-S7). When the reservation cancellation switch is turned off, the turntable is seated at the work position, and the robot performs the work and the panel finishes the panel loading on the jig B as the robot finishes the work of the jig A (S8) (S9). After that, the cycle start is turned on to move the turntable forward and the reservation cancel switch is turned off. Then, the robot stops at the turntable working position, and ends the robot after returning to the initial mode (S10-). S13), the above example When the cancel switch is turned ON, the turntable stops and returns to the load position to solve the problem, and then returns to the cycle start ON mode (S14-S16).

As described in detail above, the present invention eliminates risks by solving a problem without the operator entering the work area, thereby enabling the worker to work safely and reducing problem solving time, thereby improving work efficiency. It can be effective.
