Description

Technical Field

[0001] The invention relates to the technical field of automobile windows, and in particular to automated welding equipment for a roller-pressed window frame structure door assembly. Background Art

[0002] As an important part of the car door, the car door window frame plays a vital role in the quality of the car door and even the quality of the whole car. The car door window frame is generally divided into a roll-type window frame and an integral window frame. The width of the roll-type window frame can be designed to be relatively narrow without being restricted by the stamping and welding process, which can meet the diversity of shapes and is beneficial to the vision of the driver and passengers. When the roll-type window frame structure door assembly is produced and processed, it is necessary to use automated welding equipment to perform production welding operations on the roll-type window frame structure door assembly.

[0003] After searching, according to the patent network CN116809730A, it involves an ultra-high-strength steel roll-forming welding equipment and processing method. The welding equipment includes a first supporting structure, a second supporting structure and a base, wherein the first supporting structure and the second supporting structure are arranged opposite to each other; the first supporting mechanism and the second supporting structure are both provided with the same first lifting mechanism, and a second lifting mechanism connected to the first lifting mechanism; a processing area is formed between the first acting part, the second acting part and the base. The invention adjusts the high-strength steel forming process through a suitable clamping structure, solves the problems of welding forming angle and material dezincification, and finally achieves a consistent forming effect; a set of clamping rollers, i.e., the second acting part, is installed on the upper part of the tooling, which can effectively adjust the clamping force of the formed parts, which not only ensures the welding quality, but also avoids dezincification due to excessive clamping friction. The lower part adopts a support copper block (base) for effective support to ensure appropriate clamping force.

[0004] However, although the existing automated welding equipment can perform better automated welding operations on the roller-pressed window frame structure door assembly when in use, when the roller-pressed window frame structure door assembly is welded and fed, the automatic cleaning effect of the surface impurities of the roller-pressed window frame structure door assembly before welding is not high, so that when the roller-pressed window frame structure door assembly is cleaned by the wiping plate, the engagement and disassembly effect of the wiping plate is not high. At the same time, when the roller-pressed window frame structure door assembly is transported and welded by the conveyor belt, the dust adsorbed on the surface of the conveyor belt during long-term use is also not cleaned synchronously, which reduces the cleanliness of the surface of the roller-pressed window frame structure door assembly during welding, resulting in burrs or protrusions when the roller-pressed window frame structure door assembly is welded, affecting the welding processing quality of the roller-pressed window frame structure door assembly, and failing to meet people's use needs.

[0053] Next, when the cleaning scraper 23 and the wiping block 29 are used to clean the roller window frame for a long time, in order to improve the convenience of the cleaning scraper 23 and the wiping block 29 for engagement, disassembly, replacement and use, the second bolt 3003 and the third bolt 3007 can be rotated respectively, and under the action of the second nut 3002 and the third nut 3006, the second bolt 3003 slides out of the second slot 3004, and the third bolt 3007 slides out of the third slot 3008, so as to achieve the effect of disassembly, replacement and use of the cleaning scraper 23 and the wiping block 29;

[0054] Finally, when the rolled window frame is being transported and welded for a long time via the conveyor belt 3, in order to improve the surface cleanliness of the conveyor belt 3 during long-term use, the third servo motor 3101 can be turned on to drive the lifting block 3103 to slide along the inner wall of the slide groove 3104 through the rotation of the second threaded rod 3102, so that the cleaning brush 3105 is in contact with the surface of the conveyor belt 3, and under the transmission of the conveyor belt 3, the cleaning brush 3105 performs a cleaning movement on the conveyor belt 3, thereby achieving the effect of improving the contact cleanliness between the rolled window frame and the conveyor belt 3.
