AI Technical Summary

Technical Problem

The replacement of consumables in existing welding robots relies on manual operation, which leads to fluctuations in welding quality. Manual operation also carries the risk of forgetting steps. Existing automated devices require multiple power sources, are large in size, have a high failure rate, cannot adapt to consumables of different sizes, and are prone to damaging consumables.

Method used

Design an automated welding torch consumable replacement device, which uses electric and servo motor driven grippers and torque adjusters to achieve automated disassembly and assembly of consumables. Combined with pressure sensors and micro sensors for real-time monitoring, it ensures replacement quality and adapts to different sizes, and uses a single power source.

Benefits of technology

It enables automated replacement of consumables, reduces labor costs, improves the stability of replacement quality, adapts to consumables of different sizes, reduces failure rate, avoids consumable damage, and realizes fully automated spare parts management and early warning functions.

Abstract

The invention discloses an automatic welding gun consumable replacement device for robot welding. The automatic welding gun consumable replacement device comprises a welding gun welding material replacement platform, and the welding gun welding material replacement platform is provided with a nozzle dismounting and mounting station, a contact tube dismounting station and a contact tube mounting station; the nozzle disassembling and assembling station comprises a nozzle disassembling and assembling base rotationally installed on the welding gun welding material replacing platform, and first clamping jaws which are evenly distributed are slidably connected to the top of the nozzle disassembling and assembling base. According to the device, a device with the higher automation degree is adopted for automatically replacing welding gun consumables for robot welding, a manual replacement mode is replaced, the labor cost is reduced, single electric power energy is adopted, the obtaining mode is more convenient, a first clamping jaw and a second clamping jaw can be matched with nozzles and contact tubes of different sizes correspondingly, and the application range is wider; the nozzle and the contact tube are protected in the disassembly and assembly process, and therefore the replacement effect and the use quality of the nozzle and the contact tube are guaranteed.
