Description

Technical Field

[0001] The present invention relates to the technical field of metal welding, and particularly to an automatic laser welder for metal sheets. Background Art

[0002] An automatic laser welder for metal sheets is an automated device specifically used for efficiently and precisely welding metal sheets. It uses a laser beam with a high energy density as a heat source. The laser beam is focused by a focusing lens onto a very small spot, thereby forming a highly concentrated heat area on the surface of the metal material, achieving local rapid heating and melting to complete the welding process.

[0003] In Chinese Patent CN102886896B, a welding device for all-plastic composite sheets is disclosed. The outer heating component and the inner heating component are both provided with heating tubes using an electric heating method. The steel belt and the sheet move synchronously, and the outer surface of the sheet is heated by the steel belt, while the inner heating component simultaneously heats the inner surface of the sheet to achieve the purpose of welding the sheet. First, the welding device in the above application uses an electric heating method, heating the inner and outer surfaces of the sheet simultaneously through the steel belt and the inner heating component, and manual slicing alignment and welding are required. Although the welding device in the comparative document has an automated design, the overall degree of automation is relatively low.

For example, the drum 904 can be firmly fixed to the connecting frame 903 through multiple high-strength bolts, or a quick-release clamp can be used to achieve quick installation and disassembly. This design not only ensures the stability of the connection, but also facilitates the operator to quickly replace the drum 904 when needed, reducing the downtime and improving the production efficiency. Since such fixing methods have been widely used in related fields and their technologies and principles are well-known to those skilled in the art, there is no need to elaborate on this too much in this application. The focus should be placed on the unique innovation points and technical improvements of the present invention, such as automatic control, precise alignment and improvement of welding quality, etc.

[0049] The working principle of the above embodiment is as follows:

[0050] Place the metal sheet to be welded on the material placement rack 1 and prepare to enter the welding process. The material feeding mechanism 6 is responsible for transporting the metal sheet from the material placement rack 1 to the welding area. Through the operation of the X module A602, the upper module slider moves, driving the drive box 603 to move along the X-axis direction, so that the suction cup plate A609 moves above the horizontal plane of the material placement rack 1. At this time, the motor A607 on the drive box 603 drives the gear 608 to rotate, and the gear 608 meshes with the tooth groove 606 in the support frame 605, causing the support frame 605 to move downward until the suction cup plate A609 contacts the metal sheet. The electric suction cup A610 adsorbs the metal sheet. As the support frame 605 moves, the sheet is transported to the welding area. After the sheet reaches the welding area, the cylinder a7014 on the right side operates, causing the electric suction cup B7016 on the right suction cup plate B7015 to move downward and adsorb the sheet. At the same time, the X module B7012 on the right side operates to push the adsorbed sheet to the left. At this time, with the cooperation of the X module B7012 on the left side and the suction cup plate B7015, it fits against the left side of the top plate 7045. At the same time, the cooperation of the X module B7012 on the right side and the electric suction cup B7016 on the right side causes another metal sheet to fit against the right side of the top plate 7045. At the same time, the operation of the cylinder b7020 in its assembly can cause the push plate 7023 to push the metal sheet backward. When the metal sheet fits against the baffle 7024, the alignment of the two metal sheets on both sides is completed. After alignment, the cylinder i 7039 outputs a contraction, driving the pressure block A7040 downward. After the pressure blocks A7040 on both sides move downward, they press the two metal sheets to be welded to complete the positioning. At the same time, the output shaft of the cylinder c7032 contracts, driving the top plate 7045 downward. At this time, there is a certain gap between the two movable blocks 7038. Under the operation of the cylinder d7037, the two movable blocks 7038 move relative to each other to maintain a fitting state. At this time, the two metal sheets are also in a fitting state. At this time, through the operation of the Y module 7042, the connecting platform 7043 is driven forward, and at the same time, the cylinder f70442 drives the lower substrate 70443 downward, further enabling the laser welding machine body 11 inside to complete welding at the connection of the two metal sheets;

[0051] During the movement of the lower substrate 70443, the spring 70446 elongates, and the limit rod 70445 slides within the limit sleeve 70444 to provide buffering during the welding process. After welding is completed, the output shaft of the cylinder i 7039 elongates, causing the pressure block A 7040 to no longer position the metal sheet. Then, with the cooperation of the X module B 7012 and the electric suction cup B 7016 on both sides, the metal sheet is pushed to the left. At this time, the metal sheet passes between the pressure block B 804 and the mounting plate 802. After the output shaft of the cylinder g 803 contracts, the pressure block B 804 presses the metal sheet, and the slider of the XY two-axis module 801 drives the mounting plate 802 and the pressure block B 804 to move to the left. Under its frequent movement, the metal sheet can be intermittently pushed to the left to complete auxiliary feeding. The metal sheet will reach the upper side of the belt conveyor 805 and continue to be conveyed to the left by the belt conveyor 805. The adjustable positioning pressure wheel 808 driven by the cylinder j 806 is used to ensure the stability of the sheet conveying;

[0052] After welding is completed, the metal sheet will be conveyed to the winding mechanism 9. The motor C 902 drives the connecting frame 903 to rotate, driving the reel 904 to rotate for winding work. During the winding process, the pressing piece 907 presses the metal sheet under the drive of the cylinder h 906. After the light sensor 908 detects the winding state of the metal sheet, it controls the operation of the motor C 902 to ensure the smooth progress of the winding process and ensure that the welded metal sheet is correctly wound.

[0053] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
