Automatic machining device of anti-theft door frame and control system thereof

Abstract

The invention provides an automatic machining device for an anti-theft door frame, and a control system of the automatic machining device, and the automatic machining device integrates the functions of automatic feeding, cutting, assembling with welding. The automatic machining device comprises a feeding mechanism, a cutting mechanism, an assembling platform, a welding mechanism, a discharging mechanism and a control mechanism. The assembling platform is quadrilateral. The feeding mechanism, the cutting mechanism, the welding mechanism and the discharging mechanism surround the assembling platform. The feeding mechanism conveys a frame profile to the assembling platform in a longitudinal crossing and four-side independent feeding mode. The assembling platform is used for fixing the frame profile and moving the frame profile on the platform so that the cutting mechanism and the welding mechanism can obtain the machining position. The cutting mechanism is used for machining the frame profile on the assembling platform. The welding mechanism is used for welding the frame profile on the assembling platform. The discharging mechanism is sued for transferring the frame profile or a finished door frame out of the assembling platform. The control mechanism is used for controlling operation of the feeding mechanism, the cutting mechanism, the assembling platform, the welding mechanism and the discharging mechanism, and unmanned and intelligentized production is achieved.

Description

technical field [0001] The invention relates to an anti-theft door frame processing equipment, in particular to an automatic processing device and a control system for integrally forming the anti-theft door frame by cutting, assembling and welding, and also relates to a method for processing the anti-theft door frame by using the above-mentioned device. Background technique [0002] Anti-theft door is an important product related to the life and property safety of thousands of households. As the skeleton of the anti-theft door, the quality of the anti-theft door frame is directly related to the overall grade and quality of the anti-theft door. The quality of the anti-theft door frame is often checked from the following Start from several aspects. First, check whether the door frame has welding defects, such as open welding, unwelded, missing welding, etc. High-quality anti-theft doors put forward higher requirements for the welding level between the frame materials of the doo...

AI Technical Summary

Problems solved by technology

There are following deficiencies in the above processing: 1. The loading and unloading is all done manually, and the labor intensity of the workers is high, the efficiency is low, and the labor cost is high

2. The cutting angle and precision of manual cutting of workpieces by cutting machines or manual operation of machine tools are determined by the workers' proficiency, operating status and personal skills, which makes the product quality uneven

3. The seams and joints of the door frame are all welded manually. The welding quality is largely limited by the workers' personal skills, and the surface finish after manual welding is poor, which is not conducive to the post-polishing process

This patent has a certain reference value for the automation of anti-theft door frame processing. It is a semi-automatic improvement. Its cutting, welding, and assembly are not on the same platform. After each processing process is independently processed, a robot is added to carry it to the next processing process. , its essence is to use the handling robot to assemble the independent production lines together, and it is still not possible to realize fully automated production, and there will be many improper handling of the metal profiles, which will cause the deformation of the profiles, and the assembly of the deformed profiles will be too difficult to seriously affect At the same time, due to the differences in the material, weight, thickness, cutting, welding and processing methods of specific door frames between aluminum alloy and anti-theft door frame profiles (steel), automatic processing equipment and methods for aluminum alloy door frames cannot be applied to anti-theft door frames In automatic processing, the automatic processing of anti-theft door frames needs to overcome one by one technical problems for anti-theft door processing, such as the processing of feeding methods: aluminum alloy door frame profiles are small in size and light in weight, which is easy for robots to grab, while anti-theft door frames are large in size and heavy in weight. Grabbing requires a lot of power, so the cost of grabbing the robot is too high; the processing of the assembly method: the surface of the aluminum alloy profile is a regular plane, while the anti-theft door profiles are mostly irregular wavy surfaces, and the assembly diagonal of the anti-theft door requires The precision is higher; the processing of cutting method: aluminum alloy cutting can be cut in a single line and then assembled diagonally, but the precision requirements of the anti-theft door are high, and the profile of the anti-theft door is thick, so it is difficult to meet the high-quality assembly requirements after cutting in a single line
