Embodiment Construction

[0053] exist figure 1 The welding station 10 is schematically shown in . An exemplary station 10 includes a load fixture 12 that establishes a position of a workpiece 14 at the entrance to the welding station 10 . The welding station 10 contains a robot 18 which may be surrounded by a perimeter fence 16 for safety reasons.

[0054] The workpiece 14 may be placed into the load fixture 12 by an operator or automatically. Robot 18 may retrieve workpiece 14 from load fixture 12 using the robotic end of arm tool 20 , which holds the workpiece in a desired orientation and configuration. The welding torch 22 is mounted to the base 24 and, for example, spot welds the workpiece 14 .

[0055] Welding torch stations are typically employed within robotic cells for spot welding and projection welding. Such robotic cells employ one or more material handling robots to manipulate the workpiece(s) in place of heavy resistance welding guns. This enables the use of smaller, more agile, chea...

Abstract

The invention discloses a welding station. The welding station includes a welding gun; and the welding gun includes a first cap and a second cap. The welding gun can move between a working position and a maintenance position. The working position corresponds to a welding operation on at least one workpiece. A maintenance tool assembly is configured to mate with the first cap and second cap in the maintenance position. The maintenance tool assembly includes a cap extractor, a cap dispenser, and a cap trimmer. The cap extractor is configured to remove the first cap and the second cap from the welding gun. The cap dispenser is configured to provide new caps for the welding gun for installation. The cap trimmer is configured to shape a face of the cap. The maintenance tool assembly includes a lift actuator and a translation actuator configured to move the maintenance tool assembly relative to the welding gun in a lift direction and a translation direction separately.

Description

[0001] This application is an application for an invention patent titled "Integrated Electrode Maintenance Device for Robotic Welding Units", with an international filing date of June 12, 2018, an international application number of PCT / CA2018 / 050702, and a national application number of 201880095633.1 Divisional application. technical field [0002] The present disclosure relates to a tool maintenance assembly for removing, replacing and reconditioning caps of welding guns. Background technique [0003] A pedestal gun station is a very common robotic cell element that contains a resistance welding gun in a location that allows access to one or more industrial robots. The industrial robot is used to handle the assembly of sheet metal stamping to feed one or more base mounted welding guns or to other equipment in a robotic cell. [0004] In the resistance spot welding process, a pair of copper alloy electrodes are pressed together on overlapping metal plate(s) at the locatio...
