Description

Technical Field

Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts. China's laser welding is at the world's advanced level. It has the technology and ability to use lasers to form complex titanium alloy components of more than 12 square meters, and has been invested in the prototype and product manufacturing of multiple domestic aviation scientific research projects.

[0003] Laser welding can be achieved by continuous or pulsed laser beams. The principle of laser welding can be divided into heat conduction welding and laser deep penetration welding. The power density is less than 104~105W / cm 2 It is heat conduction welding, in which the melting depth is shallow and the welding speed is slow; the power density is greater than 105-107W / cm 2 When welding, the metal surface is sunken into a "hole" due to the heat, forming a deep fusion weld, which has the characteristics of fast welding speed and large depth-to-width ratio.

[0004] The principle of heat conduction laser welding is: laser radiation heats the surface to be processed, and the surface heat diffuses to the inside through heat conduction. By controlling laser parameters such as laser pulse width, energy, peak power and repetition frequency, the workpiece is melted to form a specific molten pool.

[0005] Arc radiation, noise and gas smoke pollution will be generated during electric welding. Among them, arc radiation of electric welding mainly includes infrared, ultraviolet and visible light. Arc radiation acts on the human body and is absorbed by the tissues in the body, causing thermal, photochemical and ionization effects on the tissues, resulting in acute damage to human tissues. In the existing technology, a laser welding protection room is usually set up to overcome the corresponding technical problems.

[0036] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0038] The content of the present invention can be more easily understood by selecting the following preferred implementation methods and embodiments of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the field to which the present invention belongs. When there is a conflict, the definition in this specification shall prevail.

[0039] Embodiment 1: As attached Figure 1 As shown, a soundproof purification room 6 is installed outside the end of the housing 1; a negative pressure flue gas purification device 11 is installed on the housing 1; and a common sealing door 8 and a normally closed door 10 for equipment loading and unloading are installed on the side wall of the housing 1.

[0040] In the foregoing, a transfer hatch 7 is installed on the soundproof clean room 6.

[0041] In the above, a negative pressure flue gas purification device 11 is installed on the outer wall or roof of the house body 1.

[0042] In the above, the commonly used sealing door 8 is mounted in the equipment loading and unloading normally closed door 10; or, the commonly used sealing door 8 is installed separately from the equipment loading and unloading normally closed door 10.

[0043] In the foregoing, at least one observation window 9 is provided on the side wall of the housing 1, allowing the operator to observe the welding process without being directly exposed to the laser radiation.

[0044] In the above description, a tool room 13 is installed independently or in communication on the outer wall of one side of the housing 1 .

[0045] In the embodiment of the utility model, a suspension rail 4 is installed on at least one side wall of the house body 1, and the suspension rail 4 is installed horizontally along the complete side wall of the house body 1. Further, a vibration-damping and sound-absorbing front plate 5 is installed vertically between the upper side of the suspension rail 4 and the roof. Further, a common sealing door 8 and a normally closed door 10 for equipment loading and unloading are installed and sealed on the lower side of the suspension rail 4. Further, a perspective window is also installed on the common sealing door 8.

[0046] In the embodiment of the utility model, filters are provided on the fresh air constant temperature and constant pressure ventilation device 2 and the negative pressure flue gas purification device 11 .

[0047] In the embodiment of the utility model, the tooling workpiece is passed in and out of the soundproof clean room 6 through the transfer hatch 7, which reduces and avoids the entry of external dust into the house body 1, and the sound, light and smoke gas overflow during processing in the house body 1 affecting the environment, thereby greatly improving the welding efficiency.

[0048] In the embodiment of the utility model, the negative pressure flue gas purification device 11 is installed on the equipment loading and unloading normally closed door 10.

[0049] The implementation principle of this embodiment is: when it is necessary to use laser welding equipment to process the workpiece in the house body 1, first turn on the fresh air constant temperature and constant pressure ventilation device 2 and the negative pressure fume purification device 11, and in subsequent work, open and close to adjust the inlet and outlet airflows and adjust the environmental conditions in the house body 1 as needed. The gas and smoke generated during laser processing are sucked out of the house body 1 through the negative pressure fume purification device 11, and then filtered and discharged through the filter net. The smoke generated during welding can be sucked and purified, thereby preventing the smoke from being directly discharged to affect the environment of the workshop and preventing the staff from inhaling harmful gases.

[0050] Preferably, the entire inner wall and roof of the house body 1 adopt a vibration-damping and heat-insulating structure.

[0051] Preferably, the housing 1 is made of metal plates, and the laser welding process is performed by an industrial robot in a metal room, which not only can seal the laser workstation, but also can shield the corresponding electromagnetic field influence generated during the processing.

[0052] Preferably, a temperature, humidity, noise and smoke detection control device is installed in the housing 1, connected to the main control system, and further connected to the fresh air constant temperature and pressure ventilation device 2 and the negative pressure smoke purification device 11. Equipped with an advanced control system, various parameters in the welding process, such as laser power, welding speed, etc., can be monitored and regulated in real time to ensure welding quality and stability.

[0053] In the embodiment of the utility model, the transparent protective lens on the observation window 9 is provided, so that the operator can safely observe the welding operation status inside the housing 1 from the outside.

[0054] In the embodiment of the utility model, the housing 1 is further optimized and designed with the simplest structure. For example, a soundproof purification room 6 is respectively arranged at the two opposite ends of the housing 1, and a transfer hatch 7 is installed on the soundproof purification room 6; and a set of suspension rails 4 are respectively installed on the outer walls of the other two opposite sides of the housing 1.

[0055] In the embodiment of the utility model, the fresh air constant temperature and constant pressure ventilation device 2 and the negative pressure fume purification device 11 are installed at opposite ends or opposite sides of the house body 1, so as to form a smooth full-area in-and-out fast and stable ventilation environment in the open house body 1.

[0056] In the embodiment of the present invention, laser welding is a highly specialized technology, and safety regulations must be strictly followed during operation. It should be ensured that the operator has received professional training and is familiar with all safety operating procedures.

[0057] The implementation principle of this embodiment is: with the increasing popularity of laser welding, the laser welding speed is fast, the weld is small, and the requirements for welding quality and the aesthetics of the weld are getting higher and higher. The laser automatic welding cover protection house is used to prevent the laser from causing harm to the operator. That is, you can choose to build and install the house body 1 first, then load and unload the normally closed door 10 from the open equipment, install the laser welding equipment and the workbench in the house body 1, then install and close the equipment loading and unloading normally closed door 10 on the hanging slide rail 4, and then install the sealing strip 12 around the normally closed door 10 for loading and unloading; you can also install the laser welding equipment and the workbench first, and then cover the house body 1 outside the laser welding equipment and the workbench. Before starting the laser processing equipment, open the commonly used sealing door 8, place the workpiece and tooling materials on the workbench in the house body 1, and then the operator exits from the commonly used sealing door 8. After closing the commonly used sealing door 8, the robot starts to weld the components. During the processing, the operator can watch the monitoring video online or observe the indoor working conditions through the observation window 9. After welding is completed, the operator opens the commonly used sealed door 8 to take out the workpiece and complete the welding of a component. During the work process, when the workpiece and tooling need to be in and out, it is completed through the soundproof clean room 6 and the transfer hatch 7. When welding some larger parts, in order to ensure smooth operation, the equipment loading and unloading normally closed door 10 can also be temporarily opened. The attached tool room 13 is used according to specific needs.

[0058] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.
