It is widely used in automobile manufacturing, electronic devices, aerospace and other industries. With the popularization of domestic laser welding equipment, its application in the home appliance industry has gradually increased, such as steam oven liner, washing machine liner, dishwasher liner, etc. Since the application scenarios of the home appliance industry are mainly thin plate materials (0.3mm-0.8mm), the appearance and quality of the weld are required to be higher, and secondary repairs such as repair welding cannot be performed after the thin plate is welded.

[0054] Figure 1 The three-dimensional structural diagram of the welding equipment provided in the embodiment of the present application is illustrated as follows: Figure 1 As shown, the present application provides a welding device, which includes a carrier 20, a first clamping component 30, a second clamping component 40, a pushing component 50 and a welding component 60. The first clamping component 30 is arranged above the carrier 20, and the first clamping component 30 is used to fix the first plate body to prevent the first plate body from moving during the welding process, so that the welding gap changes and causes the problem of welding deviation. The second clamping component 40 is arranged above the carrier 20, and the second clamping component 40 is used to fix the second plate body 70. The pushing component 50 is arranged on one side of the carrier 20, and the pushing component 50 is used to push the second plate body 70 to move toward the first plate body. The welding component 60 is arranged above the carrier 20, and the welding component 60 is used to weld the gap after the pushing component 50 pushes the second plate body 70 to move.

[0055] It can be understood that the welding equipment also includes a base 10, a bearing platform 20 is arranged on the base 10, the bearing platform 20 is suitable for placing a thin plate-like cavity, a first plate body (not shown) and a second plate body 70 are placed on the bearing platform 20, a first clamping component 30 and a second clamping component 40 are arranged above the bearing platform 20, and a pushing component 50 is arranged on the base 10. In this embodiment, the pushing component 50 is located on the left side of the bearing platform 20. Of course, the position of the pushing component 50 is not limited thereto, and the pushing component 50 can also be located on the right side of the bearing platform 20. The pushing component 50 is suitable for pushing the second plate body 70 close to the first plate body, thereby realizing real-time adjustment and control of the butt welding gap.

[0056] The welding component 60 includes a welding head assembly and a welding head driving assembly, the welding head driving assembly is connected to the welding head assembly, and the welding head driving assembly is suitable for driving the welding head assembly to move at a uniform speed along the length direction of the gap. The welding head assembly is suitable for welding the gap that meets the welding requirements.

[0057] It should be noted here that satisfying the welding requirements in the present application means that the width of the gap is smaller than the maximum welding width of laser welding.

[0058] Figure 2 One of the flow charts of the welding method provided in the embodiment of the present application is illustrated, such as Figure 2 As shown, the welding method is based on a welding device, which includes a first pressing component 30, a second pressing component 40, a pushing component 50 and a welding component 60. The welding method includes:

[0059] Step S100, receiving a welding start instruction;

[0060] Step S200, controlling the first pressing component 30 to fix the first plate body, and controlling the second pressing component 40 to fix the second plate body 70;

[0061] Step S300 , controlling the welding component 60 to weld the gap after the pushing component 50 pushes the second plate 70 to move.

[0062] According to the welding method of the embodiment of the present application, the pushing component 50 pushes the second plate body 70 toward the first plate body, so that a gap that meets the welding requirements is formed between the second plate body 70 and the first plate body, and then the gap that meets the welding requirements is welded by the welding component 60, thereby realizing real-time adjustment and control of the butt welding gap, ensuring that the welding gap meets the laser welding requirements, and improving the quality of butt welding forming of thin plate cavities.

[0063] It can be understood that the first clamping component 30 includes a positioning component 31 and a first clamping component 32; the positioning component 31 is disposed on the base 10 and is located below the support platform 20. The step of controlling the first clamping component 30 to fix the first plate body includes:

[0064] Control the positioning assembly 31 to rise, so as to position the first plate body at a side away from the second plate body 70;

[0065] The first plate body is positioned on the side away from the second plate body 70 by the positioning assembly 31, so as to realize the edge positioning of the first plate body and prevent the first plate body from moving away from the second plate body 70, thereby ensuring the consistency of the welding trajectory, avoiding welding deviation, and improving the quality of thin plate cavity butt welding.

[0066] The first pressing assembly 32 is controlled to press the first plate body to fix the first plate body.

[0067] The first pressing assembly 32 is pressed against the upper surface of the first plate body, so that the first plate body is clamped between the first pressing assembly 32 and the supporting platform 20 , thereby fixing the first plate body.

[0068] It is understandable that the first clamping assembly 32 includes a first clamping block and a first pressing member, and the first pressing member includes a first cylinder. Of course, the specific type of the first pressing member is not limited thereto, and may also be an oil cylinder, a linear push rod, or other linear drive components. The first clamping block is connected to the telescopic rod of the first pressing member. When the telescopic rod of the first pressing member contracts, the first pressing member drives the first clamping block to move upward; when the telescopic rod of the first pressing member extends, the first pressing member drives the first clamping block to move downward, and the first clamping block is pressed against the upper surface of the first plate body, so that the first plate body is clamped between the first clamping block and the support platform 20, thereby fixing the first plate body.

[0069] It should be noted that in this embodiment, two first clamping assemblies 32 are provided, and the two first clamping assemblies 32 are arranged along the length direction of the gap (ie Figure 1 The two first pressing assemblies 32 are arranged at intervals in the front-to-back direction of the first plate body. When the two first pressing assemblies 32 press the first plate body, the two first pressing assemblies 32 move synchronously, that is, the first pressing blocks of the two first pressing assemblies 32 move upward at the same time and move downward synchronously. Of course, the number of the first pressing assemblies 32 is not limited to two, and one, three, four or more may be set, which is determined according to actual needs.

[0070] It can also be understood that the positioning assembly 31 includes a positioning member (not shown) and a positioning drive member, and the positioning drive member includes a second cylinder. Of course, the specific type of the positioning drive member is not limited thereto, and may also be an oil cylinder, a linear push rod or other linear drive assembly. The cylinder is vertically arranged on the base 10, and the telescopic rod of the cylinder is connected to the positioning member. The support platform 20 is provided with a through hole, and the positioning member is movably arranged in the through hole. When the positioning assembly rises, the telescopic rod of the cylinder extends, and the telescopic rod drives the positioning member to extend out of the through hole, and the positioning member abuts against the side of the first plate body away from the second plate body 70 to position the first plate body on the side away from the second plate body 70. The control of the positioning assembly 31 to rise includes:

[0071] The positioning driving member is controlled to drive the positioning member to extend out of the through hole, and the positioning member is brought into contact with a side of the first plate body away from the second plate body 70 .

[0072] It can be understood that the step of controlling the first pressing component 30 to fix the first plate body further includes:

[0073] The positioning assembly is controlled to descend to release the positioning of the first plate body away from the second plate body 70 .

[0074] After the first clamping assembly 32 clamps the first plate, the first plate is fixed, and the first plate will not move during the welding process. Therefore, the telescopic rod of the control cylinder is contracted to drive the positioning member to retract into the through hole, and the positioning member is separated from the first plate, thereby releasing the positioning of the first plate away from the second plate 70. Of course, during the process of the first clamping assembly 32 clamping the first plate, the positioning member may not be lowered, and the first plate is fixed by the cooperation of the positioning member and the first clamping assembly 32. Compared with the above fixing method, the fixing is more stable.

[0075] Figure 3 The second flowchart of the welding method provided in the embodiment of the present application is illustrated. Figure 3 Describe a specific embodiment of the present application, such as Figure 3 As shown, the welding methods include:

[0076] Step S100, receiving a welding start instruction;

[0077] Step S200, controlling the positioning assembly 31 to rise, so as to position the side of the first plate body away from the second plate body 70;

[0078] Step S300, controlling the first pressing assembly 32 to press the first plate body to fix the first plate body;

[0079] Step S400, controlling the positioning assembly to descend to release the positioning of the first plate away from the second plate 70;

[0080] Step S500, controlling the second pressing assembly 41 to press the second plate body 70 to fix the second plate body 70;

[0081] Step S600 , controlling the welding component 60 to weld the gap after the pushing component 50 pushes the second plate 70 to move.

[0082] It can be understood that the second pressing component 40 includes at least two second pressing components 41, and the at least two second pressing components 41 are arranged at intervals along the length direction of the gap. The second pressing component 40 and the first pressing component 30 are respectively located on both sides of the welding component 60, such as Figure 1 As shown, the first pressing component 30 is located on the left side of the welding component 60, and the second pressing component 40 is located on the right side of the welding component 60. The pushing component 50 includes a plurality of pushing components 51, and the plurality of pushing components 51 are arranged at intervals along the length direction of the gap. The pushing component 51 includes a contact block and a horizontal pushing member, and the horizontal pushing member is horizontally arranged on the base 10. The horizontal pushing member includes a third cylinder. Of course, the specific type of the horizontal pushing member is not limited thereto, and may also be an oil cylinder, a linear push rod or other linear drive components. The gap includes a plurality of gap segments, and the lengths of two adjacent gap segments may be the same or different.

[0083] The step of controlling the welding component 60 to weld the gap after the pushing component 50 pushes the second plate 70 to move includes:

[0084] Step S310, controlling the pushing assembly 51 to push the corresponding portion of the second plate 70 toward the first plate to obtain a gap segment that meets welding requirements and corresponds to the pushing assembly 51;

[0085] When one of the push components 51 pushes the corresponding part of the second plate 70 toward the first plate, the gap section corresponding to the push component 51 is reduced to a gap section that meets welding requirements. The push components 51 and the gap sections can correspond one to one, or one push component 51 can correspond to two or three gap sections.

[0086] Step S320, controlling the welding component 60 to weld the gap segment;

[0087] When one of the pushing components 51 pushes the corresponding part of the second plate body 70 toward the first plate body to obtain a gap segment that meets the welding requirements, the obtained gap segment that meets the welding requirements is welded based on the welding component 60; in this way, the pushing component 51 and the welding component 60 cooperate to complete the welding process of a gap segment.

[0088] Step S330, the above process is repeated until the first plate body and the second plate body 70 are welded.

[0089] By repeating the welding process of each gap segment mentioned above, segmented welding of the entire gap can be achieved, which can not only ensure that the front-end weld gap meets the requirements, but also avoid the gap from becoming larger during rear-end welding, thereby achieving good control of the weld gap and meeting the laser welding requirements.

[0090] It is understandable that the second clamping assembly 41 includes a second clamping block and a second pressing member, the second pressing member includes a cylinder, and the second clamping block is connected to the telescopic rod of the second pressing member. When the telescopic rod of the second pressing member contracts, the second pressing member drives the second clamping block to move upward; when the telescopic rod of the second pressing member extends, the second pressing member drives the second clamping block to move downward, and the second clamping block is pressed against the upper surface of the second plate body 70, so that the second plate body 70 is clamped between the second clamping block and the supporting platform 20, thereby fixing the second plate body 70.

[0091] It should be noted here that in this embodiment, two second clamping assemblies 41 are provided, and the two second clamping assemblies 41 are spaced apart along the length direction of the gap. In the process of clamping the second plate body 70, the two second clamping assemblies 41 move synchronously, that is, the second clamping blocks of the two second clamping assemblies 41 move upward and downward synchronously at the same time. Of course, the front end of the second plate body 70 can also be clamped by the second clamping assembly 41 at the front end, and the rear end of the second plate body 70 can be clamped by the second clamping assembly 41 at the rear end after the front end welding of the gap is completed. The use of segmented clamping can facilitate the pushing component 50 to push the second plate body 70 closer to the first plate body, and more accurately control the moving distance of the second plate body 70.

[0092] Of course, the number of the second clamping components 41 is not limited to two, and may be three, four or more, depending on actual needs.

[0093] Figure 4 The third flowchart of the welding method provided in the embodiment of the present application is illustrated. Figure 4 Describe a specific embodiment of the present application, such as Figure 4 As shown, the welding methods include:

[0094] Step S100, receiving a welding start instruction;

[0095] Step S200, controlling the positioning assembly 31 to rise, so as to position the side of the first plate body away from the second plate body 70;

[0096] Step S300, controlling the first pressing assembly 32 to press the first plate body to fix the first plate body;

[0097] Step S400, controlling the positioning assembly to descend to release the positioning of the first plate away from the second plate 70;

[0098] Step S500, controlling the second pressing assembly 41 to press the second plate body 70 to fix the second plate body 70;

[0099] Step S600, controlling the pushing assembly 51 to push the corresponding portion of the second plate 70 toward the first plate to obtain a gap section that meets welding requirements and corresponds to the pushing assembly 51;

[0100] Step S700, controlling the welding component 60 to weld the gap segment;

[0101] Step S800, the above process is repeated until the first plate body and the second plate body 70 are welded.

[0102] It can be understood that the pushing component 50 includes a pushing component 51 and a horizontal moving component (not shown). The horizontal moving component is arranged on the base 10 along the length direction of the gap. The pushing component 51 is connected to the horizontal moving component. The horizontal moving component is suitable for driving the pushing component 51 to move along the length direction of the gap, so that the pushing component 51 pushes the second plate body 70 closer to the first plate body at different positions to obtain a gap that meets the welding requirements.

[0103] The step of controlling the welding component 60 to weld the gap after the pushing component 50 pushes the second plate body 70 to move toward the first plate body includes:

[0104] Step S340, controlling the pushing assembly 51 to push the corresponding portion of the second plate body 70 toward the first plate body, so as to obtain a gap section that meets welding requirements;

[0105] Step S350, controlling the welding component 60 to weld the gap segment;

[0106] Step S360, controlling the horizontal moving component to drive the pushing component 51 to move to the next predetermined position;

[0107] Since the gap does not change after the welding component 60 welds the gap segment that meets the welding requirements, the pushing component 51 can be driven to move to the next predetermined position by the horizontal moving component, and the corresponding part of the second plate body 70 is pushed closer to the first plate body at the next predetermined position to obtain the gap segment that meets the welding requirements. The same function as multiple pushing components 51 can be achieved by cooperating with one pushing component 51 and the horizontal moving component, simplifying the structure of the welding equipment and reducing the production cost.

[0108] Step S370, the above process is repeated until the first plate body and the second plate body 70 are welded.

[0109] It can be understood that the pushing component 50 includes two pushing components 51, namely a first pushing component 51 and a second pushing component 51, and the first pushing component 51 and the second pushing component 51 are arranged side by side on the left side of the base 10. A specific embodiment of the present application is described below, and the welding method includes:

[0110] Step S100, receiving a welding start instruction;

[0111] Step S200, controlling the positioning assembly 31 to rise, so as to position the side of the first plate body away from the second plate body 70;

[0112] Step S300, controlling the first pressing assembly 32 to press the first plate body to fix the first plate body;

[0113] Step S400 , controlling the positioning assembly to descend to release the positioning of the first plate body away from the second plate body 70 .

[0114] Step S500, controlling the second pressing assembly 41 to press the second plate body 70 to fix the second plate body 70;

[0115] Step 6500, controlling the first pushing assembly 51 to push the front end of the second plate body 70 toward the first plate body, so as to obtain a gap section that meets welding requirements;

[0116] Step S700, controlling the welding component 60 to weld the gap section at the front end of the second plate body 70 that meets the welding requirements;

[0117] Step S800, controlling the second pushing assembly 51 to push the rear end of the second plate body 70 toward the first plate body to obtain a gap section that meets welding requirements;

[0118] Step S900 , controlling the welding component 60 to weld the gap section at the rear end of the second plate body 70 that meets the welding requirements.

[0119] Since the gap at the rear end is easy to open during the welding process, the second pushing assembly 51 pushes the rear end of the second plate body 70 toward the first plate body to ensure that the weld does not open and that the weld meets the welding requirements.

[0120] It should be noted here that the number of the push components 51 is not limited to two, and may also be three, four or more, depending on specific needs.

[0121] It should also be noted that when multiple pushing components 51 are provided, the welding starting point is not limited to starting from any end of the gap, and welding can also start from the middle of the gap, and then weld the two ends of the gap after the middle welding is completed.

[0122] It is understandable that although the tooling can achieve good control of the gap and meet the requirements of laser welding, the molten pool of the thin plate material has poor bridging ability and is very sensitive to gaps, burrs, etc., and welding penetration problems are very likely to occur. Therefore, the process also needs to be optimized and controlled to achieve thin plate butt welding. The traditional cavity forming method uses internal welding and does not weld through to ensure product forming, which also leads to difficulties in machine adjustment and poor product performance. Swing welding can improve the bridging ability to a certain extent, but the thin plate molten pool is small and the improvement effect is limited; negative defocus welding increases the spot and can improve the gap adaptability, but due to different energy requirements at different positions, there is still a risk of local welding penetration, especially at the rear end. Based on this, the present application combines a variety of welding methods and adjusts them according to the different energies at different positions to reduce the risk of welding penetration at the rear end, thereby achieving thin plate cavity laser butt welding.

[0123] The welding component 60 welds the gap that meets the welding requirements by one of swing welding and negative defocus welding or a combination of the two. By integrating swing welding and negative defocus welding with the segmented welding process, the welding process is optimized, wherein swing welding and negative defocus welding increase the width of the welding pool, improve its bridging ability, and reduce the tolerance to gaps and burrs.

[0124] It can be understood that the power of the welding component 60 gradually decreases along the direction from the welding start point of the gap to the welding end point of the gap.

[0125] During the welding process, the initial temperature of the welding plate is low at the beginning of welding, so the energy demand at the front end is large. After welding for a period of time, the heat of the welding plate at the rear end is accumulated, and the temperature of the welding plate rises, resulting in a reduction in energy demand. In addition, the front and rear gaps are not equal. In order to avoid welding through at the rear end, the power of the welding component 60 needs to be controlled to be reduced during the welding process to avoid the problem of welding through due to excessive heat during the welding process at the rear end. By gradually reducing the power of the welding component 60 from the welding starting point of the gap to the welding end point of the gap, it can be ensured that the welding performance at any point of the weld is the same, thereby improving the welding quality.

[0126] It should be noted here that the gradual reduction here can be linear or non-linear, as long as the power reduction of the welding component 60 falls within the above-defined range.

[0127] It can be understood that there is a first predetermined position and a second predetermined position between the welding start point of the gap and the welding end point of the gap, wherein the first predetermined position is located between the second predetermined position and the welding start point.

[0128] The output power of the welding component 60 from the welding starting point of the gap to the first predetermined position of the gap is 100% of the initial setting power; from the first predetermined position of the gap to the second predetermined position of the gap, the output power of the welding component 60 is 96%-98% of the initial setting power; from the second predetermined position of the gap to the welding end point of the gap, the output power of the welding component 60 is 93%-95% of the initial setting power. In this embodiment, the welding starting point of the gap is defined as 0, the first predetermined position is 1 / 3 of the gap, the second predetermined position is 3 / 4 of the gap, and the welding end point of the gap is defined as 1. In other words, the welding component 60 adopts three different power output modes during the welding process.

[0129] In this embodiment, by setting the first predetermined position and the second predetermined position between the welding starting point and the welding end point, the gap can be divided into three sections, the first section gap is the gap between the welding starting point and the first predetermined position, the second section gap is the gap between the first predetermined position and the second predetermined position, and the third section gap is the gap between the second predetermined position and the welding end point. Since the first section gap is just beginning to weld, the output power of the welding component 60 is 100% of the initial setting power for welding, so that the temperature of the welded plate can reach the welding required temperature, ensuring that the welding effect meets the welding requirements. Since the second section gap is after the first section of welding, the welded plate has accumulated heat, and the temperature of the welded plate rises. The output power of the welding component 60 is 96%-98% of the initial setting power for welding, which can prevent the welded plate from being welded through due to excessive temperature. Since the second section gap is after the first section of welding, the welded plate has accumulated heat, and the temperature of the welded plate rises. The output power of the welding component 60 is 96%-98% of the initial setting power for welding, which can prevent the welded plate from being welded through due to excessive temperature. The third gap is welded at the end, the welded plate has more heat accumulation, the temperature of the welded plate rises further, and the output power of the welding component 60 is 93%-95% of the initial setting power for welding, which can prevent the welded plate from being welded through due to excessive temperature. It should be noted that the number of predetermined positions is not limited to two, and can also be three, four or more, which is specifically determined according to the length of the gap.

[0130] It should also be noted here that the welding starting point of the gap refers to the end of the gap close to the front end of the first plate body, and the welding end point of the gap refers to the end of the gap close to the rear end of the first plate body. Of course, when the welding direction changes, the positions of the welding starting point of the gap and the welding end point of the gap are interchanged.

[0131] In summary, the welding method of the present application pushes the second plate body 70 toward the first plate body through the pushing component 50, so that a gap that meets the welding requirements is formed between the second plate body 70 and the first plate body, and then the gap that meets the welding requirements is welded through the welding component 60, thereby realizing real-time adjustment and control of the butt welding gap, and ensuring that the welding gap meets the laser welding requirements. By integrating multiple welding processes and controlling the laser power in sections, the occurrence of welding penetration problems is avoided. By implementing both welding tooling control and welding process adjustment simultaneously, defects such as welding penetration and welding deviation can be effectively avoided, thereby improving the quality of butt welding of thin plate cavities. In addition, due to the use of an automated welding method, the assembly requirements for thin plate cavities are reduced, and welding efficiency is improved.
