Problems solved by technology

During the welding process, porosity, virtual welding, slag inclusion and missing welding will still occur, and arc radiation, high-frequency electromagnetic radiation and harmful gases will also be generated
[0007] 4. The multi-station welding of multiple horizontal tubes and vertical tubes of the drying towel rack cannot meet the requirements of the resistance welding process. There are great limitations in the welding process of the drying towel rack, and it can only be applied to specific drying towels. shelf

Embodiment 1

[0055] Reference attached Figure 3-4 After welding, the towel rack is lowered to the initial intermediate conveying device 4, and the intermediate conveying device transmits the towel rack to the feeding conveying device 6, and then the next towel rack to be welded enters the intermediate conveying device 4 and then performs the next welding cycle.

[0056] The first partition L 1A first material blocking mechanism 12 consistent with the structure of the second material blocking mechanism 8 is provided at the place, which is used to block the towel rack on the incoming material conveying device 5 from continuing to advance during the welding process, so as to prevent the lifting mechanism 7 from being lowered after welding. When the towel rack is stacked with the incoming material towel rack, the unwelded towel rack is omitted. In the process, the time required for welding is matched with the time of the incoming material to avoid the gradual increase of the towel rack retain...

Embodiment 2

[0065] Reference attached Figure 9 , on the basis of embodiment 1, the difference between the welding method in this embodiment and the welding method of embodiment 1 is only:

[0066] Step S3, laser welding: the lifting mechanism 7 moves down to a predetermined height to provide space for the towel rack to turn over, and the laser welding machine 200 performs continuous laser welding on the position to be welded on one side of the towel rack under the preset program of the three-dimensional adjustment platform 100, Then, the longitudinal positioning cylinder 10 resets, the motor 14 drives the towel rack to turn over 180°, and the longitudinal positioning cylinder 10 moves again to clamp the towel rack. The laser welding machine 200 continues to continuously laser weld the unwelded side, and the visual tracking system 300 Track the welding position and display the welding process on the computer monitor, and reset the laser welding machine to the top of the towel rack after w...

Embodiment 3

[0070] Reference attached Figure 10 , for the situation that the rate of incoming material is greater than the rate of laser welding of a single towel rack, in the schemes of embodiments 1 and 2, the number of follow-up incoming towel racks that are blocked by the first material blocking mechanism 12 gradually increases, and accumulates on the incoming material conveying device 5, that is, the single laser welding machine 200 is the bottleneck of the process, and it is not applicable to the production line where the pre-order assembly process speed is greater than the welding speed. Based on this, in this embodiment, multiple laser welding machines 200 are installed on the same conveying device to compensate for the drying rate.

[0071] On the basis of Embodiment 2, the output of the jacking cylinder 701 is connected to the side of the jacking platform 702, that is, the output rod of the jacking cylinder 701 is located at the side of the intermediate transmission device 4, t...

Abstract

A laser welding device for drying a towel rack is used for welding a transverse rod and a vertical rod of the towel rack and comprises a three-dimensional adjusting platform, a laser welding machine, a laser welding device and a control device. The laser welding machine is arranged on the three-dimensional adjusting platform, generates high-energy laser irradiating the welding position of the towel rack and is used for welding the transverse rod and the vertical rod; and the visual tracking system obtains video information of the welding position and is used for tracking the welding position and displaying the welding process on a computer display. According to the structural characteristics of the towel rack, a welding track can be obtained according to a model, and then a laser welding mode easy to control by a program is adopted, so that welding flux plastic and quality are improved; and a jacking mechanism and a positioning mechanism are arranged according to structural characteristics, so that continuous laser welding is realized. In terms of comprehensive benefits, the welding cost can be reduced by 70% compared with the original cost, full coverage of similar products is met through laser tracking, and the cost is greatly saved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a laser welding device for drying towel racks, and also relates to a welding method for drying towel racks based on laser welding equipment. Background technique [0002] There are a variety of novel drying towel racks on the market, with beautiful appearance and special-shaped tubes such as round tubes, square tubes, flat tubes and waist-shaped tubes; the main production materials of drying towel racks are also low-carbon steel, stainless steel, aluminum, etc. Alloy and copper alloy and other materials; central heating and electric heating elements are used as heat sources to dry and sterilize towels and clothes. [0003] The diversity of raw materials and wall thicknesses of drying towel racks will inevitably lead to a variety of welding processes; at present, there are mainly four welding processes: brazing, manual gas welding, argon arc welding and resistance welding. These welding pro...
