Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to an intelligent integrated laser welding machine. Background Art

[0002] Laser welding machine, also commonly known as laser welding machine, laser welding machine, is a machine used for laser welding of material processing. Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has a high aspect ratio, a small weld width, a small heat-affected zone, small deformation, fast welding speed, smooth and beautiful welds, no post-welding treatment or only simple treatment, high weld quality, no pores, can be precisely controlled, small focusing spot, high positioning accuracy, and easy automation.

[0003] Laser welding machines can realize automated welding through programming to meet different production needs. They can also adapt to the welding of workpieces of various complex shapes and have high flexibility. Laser welding machines have the characteristics of high precision, high efficiency and high reliability, bringing new welding solutions to various industries and reshaping traditional welding processes.

[0004] When welding thin-walled metal materials such as stainless steel plates and aluminum plates, although the laser welding machine has a higher weld quality than other welding methods, in order to meet some special welding requirements, such as when used in the food industry or high-precision machinery and equipment, it is also necessary to perform subsequent grinding and polishing on the weld to make the weld surface smoother. However, in the existing model, the workpiece needs to be removed and moved away for separate processing after welding is completed, the process is scattered, and the process route is long; when operating the laser welding machine to weld the workpiece, the two workpieces need to be placed in appropriate positions to ensure that the gap and alignment between the workpieces meet the requirements, and the workpieces must be fixed to ensure the stability and accuracy of the welding process. When using the existing laser welding machine, the workpieces are placed manually, and the errors caused by manual operation can easily cause the gap and alignment between the workpieces to not meet the established requirements, thereby affecting the welding accuracy. After the workpieces are fixed, if you want to adjust the relative position between the workpieces, you need to reinstall the workpieces, which is inconvenient and cumbersome.

DETAILED DESCRIPTION

[0053] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0054] like Figure 1-11 As shown, an intelligent integrated laser welding machine is characterized in that it includes: a welding machine body 1, a welding platform 2 located on the welding machine body 1, a strip table 3 arranged on the side of the welding platform 2, and the strip table 3 is flush with the surface of the welding platform 2, two groups of fixed-point parts 4 mirror-arranged on the strip table 3, and the two groups of fixed-point parts 4 are respectively located on both sides of the welding platform 2, two groups of voltage stabilizing components 5 respectively arranged on the two groups of the fixed-point parts 4, a suction connection mechanism 6 arranged on one group of the voltage stabilizing components 5, and a polishing part 7 arranged on the strip table 3 and connected to one group of the fixed-point parts 4;

[0055] The front ends of the two groups of fixed point parts 4 are at the same distance from the welding platform 2;

[0056] The suction mechanism 6 and the polishing part 7 are located on the same side, wherein:

[0057] Insert two peripheral workpieces into the two sets of the fixed-point parts 4 respectively, and the two sets of the fixed-point parts 4 can respectively preliminarily position the two peripheral workpieces to facilitate accurate alignment of the two peripheral workpieces;

[0058] Driving the two groups of the voltage stabilizing components 5 can respectively press down the two peripheral workpieces to apply pressure to the workpieces;

[0059] The suction connection mechanism 6 is suitable for firmly adsorbing the workpiece after welding, so that the workpiece is connected to the corresponding fixed point part 4 via the suction connection mechanism 6 and the voltage stabilizing component 5;

[0060] The grinding part 7 is suitable for automatically grinding the weld seam of the workpiece. Under the action of the two groups of fixed-point parts 4, the intelligent integrated laser welding machine can quickly position the two workpieces to be welded, and can quickly and conveniently place the workpieces accurately at the predetermined position to ensure that the two workpieces are aligned. At the same time, the two workpieces can be pushed toward each other synchronously so that the two workpieces gradually approach each other until the welding edges of the two workpieces reach the predetermined welding position, thereby ensuring the precise control of the gap and alignment between the workpieces, effectively preventing the situation where the placement of the two workpieces does not meet the predetermined requirements, and ensuring the welding accuracy. The two groups of voltage-stabilizing components 5 can be respectively attached to the two groups of fixed-point parts 4, and after the two workpieces are arranged in place, the two workpieces can be automatically pressed down on the welding platform 2 or the strip table 3, thereby fixing the workpieces and ensuring the stability and accuracy of the welding process. At the same time, the voltage-stabilizing component 5 can quickly cancel the pressing on the workpiece, thereby facilitating the alignment of the workpieces. The positions of the workpieces are adjusted to ensure the simplicity of the operation process. Under the joint action of the suction mechanism 6 and the grinding part 7, the welded workpiece can be automatically dragged to the post-processing area immediately after welding is completed, and the weld can be ground and polished, so that the subsequent processing of the weld can be completed immediately after welding, thereby eliminating the long-distance transfer process of the workpiece and the separate post-processing area, effectively concentrating the overall process and shortening the process route. At the same time, under the double grinding and polishing of the grinding part 7, the quality of grinding and polishing can be guaranteed, and the smoothness of the weld can be ensured to meet the use requirements. The intelligent integrated laser welding machine integrates the placement, fixation and subsequent grinding of the workpiece into one, improves the diversity of the effect, makes the operation and processing process more convenient, effectively improves the actual use experience, and adopts automatic control in many places to improve the intelligence and the accuracy of various tasks in the processing process, and optimizes the processing effect as a whole.

[0061] Optionally, the fixed-point part 4 includes an electric cylinder 41 arranged on the strip table 3, a bin body 42 placed on the strip table 3, and the bin body 42 is located in front of the electric cylinder 41, a three-point transmission member 43 installed on the output end of the electric cylinder 41 and connected to the back of the bin body 42, two groups of springs 44 with one end respectively installed on the left and right inner walls of the bin body 42, two rectangular plates 45 respectively connected to the other ends of the two groups of springs 44, and two elastic cloths 46 respectively arranged between the two rectangular plates 45 and the bin body 42;

[0062] The lower end surfaces of the two rectangular plates 45 are in contact with the strip table 3. During welding, two workpieces such as stainless steel plates or aluminum plates are respectively inserted between the two rectangular plates 45 of the two sets of fixed point parts 4 until the workpiece is pushed inwardly to the inner wall of the bin body 42. In the process of pushing the workpiece inwardly, the workpiece squeezes the two rectangular plates 45 to both sides and compresses the corresponding springs 44. At the same time, under the elastic force of the springs 44 on both sides, the position of the workpiece is automatically adjusted. If the workpiece squeezes the spring 44 on one side too much, the spring 44 on that side rebounds and pushes the workpiece to the other side, so that the workpiece is in the center of the bin body 42, thereby quickly completing the initial positioning of the workpiece and ensuring that the two workpieces are accurately aligned, and both workpieces are placed in the bin body 42. The inner rear driving electric cylinder 41 pushes the bin body 42 forward through the three-point transmission part 43, so that the two workpieces move synchronously toward the center of the welding platform 2 until the two workpieces are pushed to the predetermined position and then the electric cylinder 41 is stopped. The electric cylinder 41 is used as a driving force to place the two workpieces in a suitable welding position, and the workpieces are pushed forward quantitatively according to the size of the workpieces and the welding requirements, which effectively ensures the precise control of the gap and alignment between the workpieces, prevents the placement of the two workpieces from not meeting the predetermined requirements, and ensures the welding accuracy.

[0066] The vacuum suction cup 65 is against the pressure arm 59. After welding is completed, the pressure arm 59 and the pressure strip 591 on the side opposite to the suction connection mechanism 6 of the first motor 55 are driven to lift up, and the pressure arm 59 and the pressure strip 591 on the same side as the suction connection mechanism 6 are lifted up slightly, so that the pressure strip 591 does not apply too much pressure to the workpiece, and the pressure strip 591 is kept in contact with the workpiece, and the first electric push rod 61 is driven to push the outer sleeve 63 forward to separate the vacuum suction cup 65 from the pressure arm 59. After the vacuum suction cup 65 separates from the pressure arm 59, the inner rod 64 is pressed under the action of its own weight. Slide downward to make the vacuum suction cup 65 stick to the workpiece, and then start the external vacuum equipment to suck, so that negative pressure is generated in the vacuum suction cup 65, and the workpiece is sucked firmly, thereby connecting the workpiece with the suction connection mechanism 6 and the voltage stabilizing component 5 and the fixed point part 4 as a whole; close the external vacuum equipment and drive the first motor 55 to lean back until the bottom of the vacuum suction cup 65 faces upward. At this time, the inner rod 64 automatically retreats into the outer sleeve 63, and then the first electric push rod 61 is driven to retract its output shaft, so that the vacuum suction cup 65 can be pulled back to make it rest against the pressure arm 59 again.

After the vacuum suction cup 65 sucks the workpiece firmly, the electric cylinder 41 is first reset to make its output shaft completely retracted, and then the second motor 75 is driven to use the engagement of the second gear 76 and the rack 73 to move the rack 73 backward into the rectangular cavity box 74, so that the tail sleeve 72 is pulled backward along the rectangular groove 71, and then the fixed point part 4, the voltage stabilizing component 5 and the suction connection mechanism 6 on this side are moved backward as a whole to pull the welded workpiece backward. After the workpiece is pulled into place, that is, the weld on the workpiece is aligned with the first When a sand piece 798 is aligned, the second motor 75 is stopped, and then the vacuum suction cup 65 is reset to make it rest against the pressure arm 59 again, and then the pressure strip 591 on this side is used to press the workpiece again, and then the second electric push rod 792 is continuously driven to pull the support plate 78 down, until the first sand piece 798 is attached to the weld, and then the impact cylinder 794 is driven to push and pull the top strip 793 back and forth quickly in the fork arm 79, so that the first sand piece 798 is synchronously rubbed quickly on the weld of the workpiece to grind and polish the weld, so that the weld can be ground and polished immediately after welding, eliminating the long-distance transfer process of the workpiece and the separate post-processing area, effectively concentrating the overall process and shortening the process route.
