Description
Technical Field
The utility model is suitable for a screw welding machine welding class equipment, concretely relates to screw welding machine welding discernment alarm device.
Background
In the automobile industry with different brands, in the white automobile body splicing welding process, screws with different quantities need to be welded on one plate, however, the quality problem of screw leakage often occurs when workers on the same line weld, and the result is not imaginable if the quality problem is not found in time. Aiming at the problem, a technical device which detects whether welding conditions are met or not, prompts an alarm if a specified number of screws are not welded and can be opened only after a clamp is welded is designed through an autonomous design so as to solve the problem.
SUMMERY OF THE UTILITY MODEL
For solving the problem of easy missing welding quality of the welding screws of the metal plate parts of the white automobile body, the utility model provides a welding identification and alarm device of the screw welding machine, the concrete technical scheme is as follows: .
The utility model provides a screw welding machine welding discernment alarm device which characterized in that: the device comprises a PLC controller, a screw welding machine and a machine tool motor; the PLC is respectively connected with the screw welding machine and the machine tool motor through electric signals; detection switches are arranged in welding positioning holes of the welding fixture and are in electric signal connection with the PLC; the PLC controller is provided with the alarm, each detect switch all is connected to the terminal that PLC controller input module corresponds, the welder electricity signal connection of screw welding machine corresponds the terminal to PLC controller output module.
Further, welding jig's welding locating hole sets up a plurality ofly, all is provided with detection switch in every.
Further, the alarm is a flashing light alarm or a buzzer alarm.
The utility model discloses the device, only after the whole welding of metal plate spare screw is accomplished, anchor clamps just can open, if wherein have arbitrary screw not to weld, the PLC controller will report to the police this moment, reminds this station staff, and up to last screw welding completion, anchor clamps just allow to open this moment to this gets into next metal plate spare welding action. The utility model discloses an alarm setting can effectively stop the phenomenon emergence that the screw missed welding.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
the utility model provides a screw welding machine welding discernment alarm device which characterized in that: the device comprises a PLC controller, a screw welding machine and a machine tool motor; the PLC is respectively connected with the screw welding machine and the machine tool motor through electric signals; detection switches are arranged in welding positioning holes of the welding fixture and are in electric signal connection with the PLC; the PLC controller is provided with the alarm, each detect switch all is connected to the terminal that PLC controller input module corresponds, the welder electricity signal connection of screw welding machine corresponds the terminal to PLC controller output module. The welding fixture's welding locating hole sets up a plurality ofly, all is provided with detection switch in every. The alarm is a flashing light alarm or a buzzer alarm.
This embodiment is provided with 5 welding points, all is provided with detection switch in 5 welding position holes to correspond and be connected to the PLC controller. The specific operation flow is as follows: when the screw welding gun is placed in the positioning hole 1 and the detection switch 1 is sensed, the worker presses the starting switch, the screw welding gun performs the welding action 1, and the screw welding action in the positioning hole 1 is completed; a worker pulls out the welding gun from the positioning hole 1, puts the welding gun into the positioning hole 2, and after sensing the detection switch 2, the worker presses the starting switch, the screw welding gun performs the welding action 2, and the welding action of the screw in the positioning hole 2 is completed; a worker pulls out the welding gun from the positioning hole 2, puts the welding gun into the positioning hole 3, and after sensing the detection switch 3, the worker presses the starting switch, the screw welding gun performs the welding action 3, and the welding action of the screw in the positioning hole 3 is completed; a worker pulls out the welding gun from the positioning hole 3, puts the welding gun into the positioning hole 4, and after sensing the detection switch 4, the worker presses the starting switch, the screw welding gun performs the welding action 4, and the welding action of the screw in the positioning hole 4 is completed; the welding gun is pulled out of the positioning hole 4 by a worker and placed into the positioning hole 5, the worker presses the starting switch after sensing the detection switch 5, the screw welding gun performs the welding action 5, and the welding action of the screw in the positioning hole 5 is completed; and if any one of the screws is not welded, the plc alarms to remind the staff at the station, and the clamp is allowed to be opened until the last screw is welded so as to enter the next plate welding action.
Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
