Description

Label welding set with many welder chucks

Technical Field

The application relates to the technical field of steel, in particular to a label welding device with multiple welding gun chucks.

Background

The label is used for marking the basic information of the steel, including the type, specification, production date and the like of the steel. In mass production, the steel material of each basic unit can be labeled by using a label according to the basic unit of the steel material batch. For example, to facilitate shipping, steel is often provided in bundles as a basic unit. The steel material with bundle as basic unit is called steel bundle, and the model, specification and production date of each group of steel bundles are identical, so that corresponding labels can be added to each group of steel bundles.

Because the steel is limited by the material property and the shape property of the steel, the tag cannot be attached by using a pin or an adhesive, and therefore, the tag is usually welded to the end face of the steel bundle by using a welding method. After the welded labels are welded, the steel bundles are still transported to the next process or the next application site by taking the bundles as a unit, and in the transportation process, the steel bundles may be in bumpy, extruded or other adverse environments, so that the labels on the end faces of the steel bundles are damaged, and the basic information corresponding to the steel bundles cannot be acquired, so that the steel bundles are difficult to be used subsequently, and waste is caused. Therefore, to avoid this situation, at least two signs are typically welded to each set of bundle ends during the welding process.

At present, label welding is mainly realized in a mode of controlling a welding gun by a robot. In the existing automatic welding process, a label welding device is installed at the free end of a robot, and a group of card taking devices and nail taking devices are respectively arranged on the end face of the label welding device. When the label is welded, firstly, the label taking device and the nail taking device are used for respectively carrying out the operations of taking the label and taking the nail, then the robot carries the label and the welding nail to move to the end face of the steel bundle, and after the label is welded to the end face of the steel bundle, the robot returns to carry out the operations of taking the label and taking the nail, so that one welding process is completed. The time required to complete one welding process is called the welding tact, which is about 30S. The welding rhythm is difficult to improve under the influence of a series of process steps, however, the current welding rhythm cannot meet the production rhythm of a steel mill, so that the output efficiency of the steel bundle is limited by the welding rhythm.

As shown in fig. 1 and 2, the present application provides a placard welding apparatus having a multi-torch cartridge, including: a housing 1 and a welded assembly 2. Wherein, the welding assembly 2 is used for welding the label on the end face of the steel bundle.

A flange 10 is arranged on the outer side of the shell 1, and the shell 1 is connected with the free end of the robot through the flange 10, so that the robot can control the label welding device to perform welding operation.

The welding assembly 2 comprises: the welding gun pushing assembly 21 is arranged in the shell 1, the welding gun chuck 22 extends to the outside of the shell 1, and the sucking disc 23 is matched with the welding gun chuck 22; the welding gun pushing assembly 21 is connected with the welding gun chuck 22 and used for controlling the welding gun chuck 22 to stretch; the welding gun chuck 22 is used for clamping welding nails, and the sucking disc 23 is used for sucking the label. After the robot moves the label welding device carrying the label and the welding nail to one side of the steel bundle, the welding gun chuck 22 welds the label on the end face of the steel bundle.

In one implementation, the torch ejection assembly 21 includes: a torch push-out cylinder 211 and a torch 212; the movable end of the welding gun push-out cylinder 211 is connected with the welding gun 212, the tail end of the welding gun 212 is fixedly connected with the welding gun chuck 22, and the welding gun push-out cylinder 211 is used for controlling the feeding motion of the welding gun 212 during welding so that the welding gun 212 drives the welding gun chuck 22 to stretch and retract. The feeding motion is the motion of the welding gun towards the label and the steel bundle during the welding process.

In one implementation, the torch push out cylinder 211 is a screw type cylinder. The thrust of the screw type cylinder is constant so that the torch 212 is pushed out with a constant thrust every time the torch push-out cylinder 211 is operated.

The welding gun chucks 22 and the flange 10 are distributed on two sides of the shell 1, and the telescopic direction of the welding gun chucks 22 is parallel to the central line of the flange 10. The flange 10 is connected with the free end of the robot, and after the label welding device is connected with the robot, the label welding device can rotate along the central line of the flange 10 under the driving of the robot, and the welding assembly 2 and the flange 10 are respectively distributed on one side of the shell 1, so that the welding assembly 2 can stretch in the direction parallel to the central line of the flange 10, and the label welding operation is executed.

In order to reduce the welding beat, in the sign welding set that this application embodiment provided, be provided with at least two sets of welding subassembly 2, the robot is in carrying out welding operation once, control sucking disc 23 all carries out inhales the tablet operation to with each the sign that sucking disc 23 sucked welds in proper order at the steel bundle terminal surface.

If the welding assembly is 2 groups, in one welding operation, the robot can return after the 2 groups of labels are completely welded, the welding beat is about 13S, and compared with the prior art that the welding assembly returns after only one label is welded in one welding operation, the welding beat is improved by at least 2 times when the welding assembly is set to be 2 groups. Similarly, if the number of the welding assemblies is 4, in one welding operation, the robot can return after the welding of all the 4 groups of labels is finished, and the welding beat can be further shortened.

The number of welding modules 2 that can be provided by the label welding apparatus cannot in principle exceed 4 groups, limited by the space inside the housing 1. In addition, typically, 2 tags need to be welded to the surface of the steel bundle. If only one label is welded according to the existing one-time welding operation, the robot transports the label-welded steel bundle to the next position after performing 2 welding operations, and the next steel bundle to be welded is then transported to the position to be welded. Because the transportation process of steel bundle needs certain time, combine the quantity that steel bundle surface needs the welding sign, this application embodiment sets up the quantity of welding subassembly 2 and is two sets of.
