Description

The utility model relates to the field of robotics and can be used in welding production, namely, it relates to a robotic welding cell with several welding posts.

Robotic cells are known from the prior art, for example, a modular production cell based on a small-sized robot (RU 201065 U1). The modular production cell of an automated production line contains a frame on which a small-sized robot is mounted, and is designed to be docked with the modular production cells of the production line and transfer the processed product between them. In this case, the small-sized robot has a working area that does not extend beyond its mounting dimensions in the horizontal plane, in which there are two transport units that have the same degree of mobility and are located with the ability to transfer the product being processed from the working area of the robot to two adjacent sides of the cell. Moreover, the first transport unit is configured to transfer the processed product to the transport unit of the adjacent cell, and the second transport unit - to the working area of the robot of the neighboring cell.

The disadvantage of the device described in this patent is that the increase in robot performance is achieved by modular connection of cells, and not in one cell, which implies complexity of the design and welding process.

Known Robotic module for resistance spot welding from patent document RU 2304498 C2, containing a welding machine, an industrial robot with welding tongs with electrodes mounted on the arm, a control system, a table with a device for securing the welded spacer grid placed on it, made in the form of a multi-jaw chuck with jaws , covering the perimeter of the mentioned grid, characterized in that the electrodes of the welding tongs are made with a spherical working surface and are equipped with a cylindrical-shaped connecting element located in the electrode holder at an angle to the perpendicular directed to the surfaces being welded, the multi-jaw chuck is equipped with a platform with depressions made on it, and on The jaws covering the perimeter of the spacer grid have grooves.

The disadvantages of this solution are the absence of a cleaning station, the absence of a tray for welding waste, safety guards and guard curtains, as well as an insufficient level of productivity.

Also, as a prototype of the claimed device, the Robotic Welding Cell Unit from patent document US 2006108342 A1 can be selected, which is a portable welding cell unit that includes a frame structure in which the first and second welding stations are located; the frame also includes a robot arm; the robot arm may be rotated between the first and second welding stations such that a workpiece can be welded at the first welding station while the workpiece is loaded or unloaded from the second welding station.

The disadvantage of this solution is insufficient welding safety, the presence of only two welding stations, which reduces productivity.

The technical result of the claimed utility model is to ensure personnel safety during the continuous welding process in a robotic cell.

The declared technical result is achieved by creating a robotic welding cell containing a welding table, a frame of a robotic complex (RC) and a frame of welding stations, a robot stand, a controller and source stand, a cleaning station stand, electrical and pneumatic preparation, circular fences, lifting protective curtains, flooring, service door, service door for the burner cleaning station, then SOG, trays for welding waste.

The claimed robotic cell is characterized by the fact that trays for welding waste, fences in a circle, a torch cleaning station, a welding table and a work stand for placing a manipulator, a controller and source stand, a frame of welding stations, lifting protective curtains, electrical and pneumatic preparation are mounted on the RTK frame , the welding station is equipped with a steel flooring, the cell contains a service door and a door for servicing the gas burner. All parts of the solution are connected to each other by screwing (screw connection).

In a private version, the robotic welding cell can be equipped with an air exhaust and purification system and a power unit for the ventilation system.

In a private version, the utility model can be supplemented with a lighting system.

In a private version, the utility model can be supplemented with laser protective barriers to enhance security.

In a private version, the utility model can be supplemented with push-button control stations to start the welding process at the corresponding welding station, pause and emergency stop.

The declared solution assumes the possibility of installing several welding stations (up to three).

The claimed utility model is illustrated by the following figures.

Dynamics of a utility model.

Welding objects and a robot for welding (14) are installed on the welding table (4) on the robot stand (1), on the controller and source stand (2) the welding process is started while the robot is welding on one table, on the second the operator removes the welded products and loads new workpieces, after which the robot begins welding on the second table, and the operator moves to the first or third table, etc. At the same time, the maintenance personnel are protected from mechanical interaction with the robot and the effects of welding splashes - due to a fence in a circle (9), from light radiation of the welding arc - due to automatic lifting protective curtains (13). Waste generated during the welding process falls into the welding waste trays (12), and waste generated during the torch cleaning process remains in a special compartment of the torch cleaning station (3). The service door (10) allows service personnel to enter the welding cell to perform equipment maintenance procedures. The EGR service door (11) allows convenient access to the burner cleaning station for replacing the working fluid, adjusting the pressure and other procedures. Electrical preparation (7) implies special places for laying signal and power cables, cables from the robot and welding machine, and cables for safety sensors. The pneumatic preparation (7) includes a pneumatic terminal with lines separated from it for supplying compressed air to the EGR and protective curtains, and an air preparation unit with a pressure regulator.

The use of the declared utility model implies an increase in ease of use and productivity by increasing the useful working time of the robot (reducing downtime/waiting time), because one robot is used for 2 or more welding stations, instead of one robot for one station. Efficiency is achieved due to the fact that in any case, the operator must load and remove workpieces and finished products at the welding station. To prevent the robot from being idle while the operator performs the above actions, the robot performs welding operations at the second or third welding station. After which the robot and operator change places, then the cycle repeats. This ensures continuity of the welding process without the need for additional robots. A cleaning system and weld waste trays also increase ease of use and productivity, while circle guards and lift-up curtains contribute to operator safety. In addition, the design of the utility model assumes the possibility of quick installation/dismantling of the cell and transfer to another site/production, as well as modernization by installing another type of robot, additional equipment: protective laser barriers, push-button control stations for starting the welding process at the corresponding welding station, pause and emergency stop, lighting inside the cell, ventilation system, various types of flooring inside the cell.

The declared utility model is new and has industrial applicability.
