Description

Technical Field

[0001] The invention belongs to the technical field of laser welding, and in particular relates to laser welding equipment for a compressor liquid storage tank. Background Art

[0002] 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, with shallow fusion and slow welding speed; the power density is greater than 105~107W / cm 2 When the laser is heated, the metal surface is sunken into a "hole", forming a deep fusion weld, which has the characteristics of fast welding speed and large depth-to-width ratio; 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 the laser parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool; the compressor fluid storage tank, also known as the high-pressure fluid storage tank, is an important component of the refrigeration system; these functions of the fluid storage tank make it play an important role in the refrigeration system, especially in the system with large load changes, its role is more significant; at the same time, the design and manufacture of the fluid storage tank need to consider many factors, such as the type of refrigeration system, the properties of the refrigerant, the working environment, etc., to ensure its normal operation and high efficiency.

[0003] At present, when using laser welding for the tank body and cover of a compressor fluid storage tank, the laser radiation heats the surface to be processed, causing the metal at the welding part of the tank body and the cover to melt, resulting in metal evaporation and generating a large amount of smoke. If the generated smoke is not collected, it will cause the smoke to pollute the environment. In addition, during welding, an oxide layer will be present at the welding part of the tank body and the cover. If the oxide layer is not treated, the welding quality will be affected.

[0036] When in use, first install the cover and tank body of the liquid storage tank with interference fit on the three-jaw chuck 13, then start the three-axis module 3 so that the laser welder 5 is at the welding position of the tank body and the cover, and adjust the angle of the laser welder 5 through the angle adjustment motor 18 so that the laser welder 5 is at a suitable angle. At this time, the laser welder 5, the industrial camera 6, the first display screen 7, the second display screen 9 and the drive motor 12 can be started, and the cover and tank body of the liquid storage tank are welded by the laser welder 5. During the welding process, the drive motor 12 will drive the three-jaw chuck 13 to rotate, and then drive the interference fit cover and tank body to rotate. The industrial camera 6 captures the picture of the welding process. After the welding is completed, the second display screen 9 displays the welding parameters. After the welding is completed, the drive motor 12 drives the welded liquid storage tank to rotate through the three-jaw chuck 13, and the industrial camera 6 captures the weld and displays it on the first display screen 7 to detect the welding quality of the weld.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, a supporting mechanism 14 for supporting the liquid storage tank is installed on the top of the mounting base 10, and the supporting mechanism 14 includes an electric telescopic rod 1401 fixedly connected to the top of the mounting base 10, and the output end of the electric telescopic rod 1401 is fixedly connected to a supporting plate 1402, and the top of the supporting plate 1402 is fixedly connected to a smoking ring 1404 through a fixing rod 1403. A smoking hole 1405 is opened on one side of the smoking ring 1404, and a ball 1406 is rotatably connected to the inner surface of the smoking ring 1404. The outer surface of the ball 1406 is in contact with the outer surface of the liquid storage tank, and the ball 1406 is made of elastic material. The inner surface of the smoking ring 1404 A mixing mechanism 17 is installed; it also includes: a smoking mechanism 15 installed in the supporting mechanism 14 and connected to the interior of the supporting mechanism 14, the smoking mechanism 15 includes a water tank 1501, a sealing plate 1502 is installed on the top of the water tank 1501, the sealing plate 1502 is sealed and connected to the water tank 1501, a connecting pipe 1505 is fixedly connected to the sealing plate 1502, an air pump 1503 is installed on the sealing plate 1502, an exhaust pipe 1504 is installed at the exhaust end of the air pump 1503, the air extraction end of the air pump 1503 is connected to the interior of the water tank 1501, and a gas purification box 1509 is installed at the air extraction end of the air pump 1503, and the gas purification box 1509 is installed. 09 is provided with an air outlet of the same size as the air pump 1503 suction end at the top, and the air outlet is connected to the inside of the air pump 1503 suction end, and the activated carbon adsorption layer, acid absorption layer, alkaline absorption layer and biofilm are installed in the gas purification box 1509 from bottom to top, and the bottom of the gas purification box 1509 is hollowed out to facilitate the gas to flow through the gas purification box 1509 into the air pump 1503, the smoking mechanism 15 also includes a connecting pipe 1505 fixedly connected to the bottom of the smoking ring 1404, and the side wall of the water tank 1501 is fixedly connected to the water adding pipe 1506, and a sealing plug is installed in the water adding pipe 1506, and it is necessary to add water to the water tank 15 01, open the sealing plug and add clean water to the water tank 1501 through the water adding pipe 1506. The water tank 1501 is filled with clean water, but the clean water does not fill the water tank 1501, thereby preventing the clean water in the water tank 1501 from entering the air pump 1503. The top of the exhaust pipe 1504 is fixedly connected with the blowing pipe 1507, and the connecting pipe 1505 is fixedly connected to the sealing plate 1502. The connecting pipe 1505 extends into the water tank 1501. A drainage hole 1508 is provided at the bottom of the water tank 1501, and a sealing plug is installed in the drainage hole 1508. When the water in the water tank 1501 needs to be replaced, open the sealing plug to drain the water.

[0038] Before installing the cover and the tank body of the liquid storage tank with interference fit on the three-jaw chuck 13, start the electric telescopic rod 1401 to extend the electric telescopic rod 1401 to facilitate the installation of the liquid storage tank. After the liquid storage tank is installed on the three-jaw chuck 13, start the electric telescopic rod 1401 again to shorten the electric telescopic rod 1401 until the smoke ring 1404 is sleeved on the right side of the welding part of the liquid storage tank, and the air blow pipe 1507 is at the welding part of the liquid storage tank. During welding, start the drive motor 12 and the air pump 15 03. When the driving motor 12 drives the liquid storage tank for welding, it will guide the rotation of the liquid storage tank through the ball bearing 1406 to avoid the eccentric rotation of the liquid storage tank, which will cause the position of the welding liquid storage tank to change, thereby ensuring the welding quality. The air pump 1503 extracts the gas in the water tank 1501, and then the water in the connecting pipe 1505 enters the water tank 1501 under the action of the air pressure in the water tank 1501. At this time, the smoke ring 1404 will extract the high-temperature smoke generated during welding through the smoke hole 1405. The high-temperature fume generated during welding enters the water in the water tank 1501 through the connecting pipe 1505. The dust in the high-temperature fume generated during welding is absorbed by the water in the water tank 1501, and the toxic gas in the fume is purified by the gas purification box 1509. The fume after removing the dust and toxic gas will be discharged into the blowing pipe 1507 through the exhaust pipe 1504, and then blown to the welding part of the liquid storage tank by the blowing pipe 1507 to remove impurities in the welding part of the liquid storage tank. And because it is high-temperature fume, Therefore, part of the water in the water tank 1501 can be evaporated, and the water vapor formed by evaporation will be blown to the welding part of the liquid storage tank through the blowing pipe 1507 along with the air flow, further improving the cleaning quality of the welding part of the liquid storage tank, and can cool the weld to a certain extent after welding. Moreover, since it is a hot air flow containing water vapor that is blown to the weld, and there is a certain gap between the blowing end of the blowing pipe 1507 and the welding part of the tank body and the cover body of the laser welder 5, it will not affect the weld.

[0039] like Figure 7 、 Figure 8 and Figure 9As shown, the laser welding equipment also includes: a grinding mechanism 16 installed on the supporting mechanism 14 for grinding the welding part of the liquid storage tank, the grinding mechanism 16 is provided with two groups, respectively located on both sides of the smoke extraction hole 1405, the grinding mechanism 16 includes a servo motor 1601 installed on the other side of the smoke extraction ring 1404, the output end of the servo motor 1601 is fixedly connected to the rotating shaft 1602, the rotating shaft 1602 passes through the smoke extraction ring 1404 and is sealed and rotatably connected to the smoke extraction ring 1404, the end of the rotating shaft 1602 is fixedly connected to the mounting column 1603, the outer surface of the mounting column 1603 is fixedly connected to the grinding ring 1604, the grinding ring 1604 corresponds to the welding part of the liquid storage tank, the blowing end of the blowing pipe 1507 is facing the corresponding part of the grinding ring 1604 and the liquid storage tank, and the outer surface of the grinding ring 1604 is provided with an arc-shaped notch so that the grinding ring 1604 cannot fit into the welding part of the liquid storage tank.

[0040] When the blowing end of the blowing pipe 1507 reaches the welding part of the liquid storage tank, the grinding ring 1604 reaches the welding part of the liquid storage tank and fits with the welding part of the liquid storage tank. At this time, the driving motor 12 and the servo motor 1601 are started, but the laser welder 5 is not started, so that the servo motor 1601 and the driving motor 12 have the same working direction, and the operation of the servo motor 1601 will drive the grinding ring 1604 to rotate through the rotating shaft 1602 and the mounting column 1603, so that the grinding ring 1604 grinds the welding part of the liquid storage tank to remove impurities and rust in the welding part, thereby ensuring the quality of the subsequent laser welder 5 welding the welding part of the liquid storage tank. When the laser welder 5 welds the liquid storage tank, the servo motor 1601 works so that the arc-shaped notch of the grinding ring 1604 faces the welding part of the liquid storage tank, thereby avoiding the grinding ring 1604 affecting the quality of the weld during welding.

[0041] When welding is completed, the servo motor 1601 and the drive motor 12 work in the same direction, so that the grinding ring 1604 grinds the weld obtained by welding. At this time, since the air pump 1503 is still in working condition, the debris generated by grinding the weld will be blown up by the air pipe 1507, sucked by the smoke hole 1405, and enter the water tank 1501, and collected by the water tank 1501, avoiding the debris from splashing everywhere and ensuring the shooting quality of the weld by the industrial camera 6, making it easier to observe the welding quality of the weld and improving the accuracy of weld detection.

[0042] like Figure 4 and Figure 10As shown, the mixing mechanism 17 includes a rotating motor 1705 installed on the inner surface of the smoking ring 1404, the output end of the rotating motor 1705 is fixedly connected to the rotating rod 1701, the bottom of the rotating rod 1701 is rotatably connected to the inner bottom of the water tank 1501, the outer surface of the rotating rod 1701 is fixedly connected to the fan blade 1702, the fan blade 1702 is located in the connecting pipe 1505, the outer surface of the rotating rod 1701 is fixedly connected to the stirring blade 1703, the stirring blade 1703 is located below the connecting pipe 1505 and in the water tank 1501, and the outer surface of the stirring blade 1703 is provided with a through hole 1704.

[0043] During use, the rotating motor 1705 is started so that the rotating motor 1705 drives the fan blade 1702 to rotate through the rotating rod 1701, and the smoke generated by welding is absorbed through the smoke extraction hole 1405. At the same time, the stirring blade 1703 is rotated to stir the high-temperature smoke entering the water tank 1501, and the through hole 1704 will expand the shear range, improve the mixing quality of the high-temperature smoke and water, and enable the water to absorb more dust in the high-temperature smoke, thereby achieving the purification of the high-temperature smoke and reducing the probability of dust in the high-temperature smoke polluting the external environment.

[0044] The specific working principle of the present invention is as follows:

[0045] When in use, first start the electric telescopic rod 1401 to extend the electric telescopic rod 1401 to facilitate the installation of the liquid storage tank, then install the cover and tank body of the liquid storage tank with interference fit on the three-jaw chuck 13. After the liquid storage tank is installed on the three-jaw chuck 13, start the electric telescopic rod 1401 again to shorten the electric telescopic rod 1401 until the smoking ring 1404 is sleeved on the right side of the welding part of the liquid storage tank, and the blowing pipe 1507 is at the welding part of the liquid storage tank. At this time, the grinding ring 1604 reaches the welding part of the liquid storage tank and is in contact with the welding part of the liquid storage tank. When the welding part of the liquid storage tank is fitted, the drive motor 12 and the servo motor 1601 can be started, but the laser welder 5 is not started, so that the servo motor 1601 and the drive motor 12 work in the same direction. The operation of the servo motor 1601 will drive the grinding ring 1604 to rotate through the rotating shaft 1602 and the mounting column 1603, so that the grinding ring 1604 grinds the welding part of the liquid storage tank to remove impurities and rust on the welding part, thereby ensuring the quality of the subsequent laser welder 5 welding on the welding part of the liquid storage tank.

[0046] After the polishing is completed, the three-axis module 3 is started so that the laser welder 5 is at the welding position of the tank body and the cover body, and the angle of the laser welder 5 is adjusted by the angle adjustment motor 18 so that the laser welder 5 is at a suitable angle. At this time, the laser welder 5, the industrial camera 6, the first display screen 7 and the second display screen 9 and the drive motor 12 can be started. The cover body and the tank body of the liquid storage tank are welded by the laser welder 5. During the welding process, the drive motor 12 will drive the three-claw chuck 13 to rotate, and then drive the interference fit cover body and tank body to rotate. The industrial camera 6 takes pictures of the welding process, and starts the servo motor 1601 to drive the motor 12 and the air pump 1503 at the beginning of welding. The operation of the servo motor 1601 will make the polishing ring 16 The arc-shaped notch of 04 is directly opposite to the welding part of the liquid storage tank, so as to avoid the grinding ring 1604 affecting the quality of the weld seam during welding. When the driving motor 12 drives the liquid storage tank for welding, it will guide the rotation of the liquid storage tank through the ball bearing 1406 to avoid the eccentric rotation of the liquid storage tank, which will cause the position of the welding liquid storage tank to change, thereby ensuring the welding quality. The air pump 1503 extracts the gas in the water tank 1501, and then the water in the connecting pipe 1505 enters the water tank 1501 under the action of the air pressure in the water tank 1501. At this time, the smoke ring 1404 will extract the smoke generated during welding through the smoke hole 1405, so that the smoke generated during welding enters the water in the water tank 1501 through the connecting pipe 1505, and the smoke generated during welding enters the water in the water tank 1501 through the water tank 1 The water in 501 absorbs the dust in the high-temperature fume generated during welding, and purifies the toxic gas in the fume through the gas purification box 1509, and then the fume after removing the dust and toxic gas will be discharged into the blowing pipe 1507 through the exhaust pipe 1504, and blown to the welding part of the liquid storage tank by the blowing pipe 1507 to remove impurities in the welding part of the liquid storage tank. Moreover, since it is high-temperature fume, it can make the water in the water tank 1501 partially evaporate, and the water vapor formed by evaporation will be blown to the welding part of the liquid storage tank through the blowing pipe 1507 along with the air flow, further improving the cleaning quality of the welding part of the liquid storage tank, and can cool the weld after welding to a certain extent, and since it is a hot air flow containing water vapor blowing to the welding part, the water vapor in the water tank 1501 can be blown to the welding part of the liquid storage tank. There is a gap between the air blowing end of the air blowing pipe 1507 and the welding part of the tank body and the cover body of the laser welder 5, so there is no influence on the weld seam. When air flows through the connecting pipe 1505, the rotating motor 1705 is started so that the rotating motor 1705 drives the fan blade 1702 to rotate through the rotating rod 1701, and absorbs the smoke generated by welding through the smoke extraction hole 1405. At the same time, the stirring blade 1703 rotates to stir the high-temperature smoke entering the water tank 1501. The through hole 1704 will expand the shear range, improve the mixing quality of the high-temperature smoke and water, and enable the water to absorb more dust in the high-temperature smoke, thereby achieving purification of the high-temperature smoke and reducing the probability of dust in the high-temperature smoke polluting the external environment.

[0047] After welding is completed, the second display screen 9 displays the welding parameters. At this time, the servo motor 1601 and the drive motor 12 work in the same direction, so that the grinding ring 1604 grinds the weld obtained by welding. Since the air pump 1503 is still in working condition, the debris generated by grinding the weld will be blown up by the air pipe 1507, sucked by the smoke hole 1405, and enter the water tank 1501, and collected by the water tank 1501, so as to avoid the debris from splashing everywhere and ensure the shooting quality of the weld by the industrial camera 6, so as to observe the welding quality of the weld more clearly. At the same time, the air flow blown out by the air pipe 1507 will clean the grinding ring 1604, so as to ensure the quality of the weld grinding by the grinding ring 1604. When the grinding ring 1604 grinds the weld, the drive motor 12 drives the welded liquid storage tank to rotate through the three-jaw chuck 13, and the industrial camera 6 shoots the weld and displays it on the first display screen 7 to detect the welding quality of the weld.

[0048] After the inspection is completed, turn off the air pump 1503, the drive motor 12 and the servo motor 1601, and then start the electric telescopic rod 1401 to move the grinding ring 1604, the air blowing pipe 1507 and the smoking ring 1404 away from the liquid storage tank, so that the liquid storage tank can be removed from the three-jaw chuck 13.

[0049] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
