Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to a welding device and a welding method for a thin iron joint interface. Background Art

[0002] In modern industrial production, thin iron materials are widely used in many fields due to their advantages of light weight and low cost, such as electronic equipment housing manufacturing, automobile parts production, and daily household appliances processing. For the processing of thin iron materials, welding is a key connection process, and its welding quality is directly related to the performance, reliability and service life of the product.

[0003] Existing welding devices usually cannot adaptively perform elastic limiting according to the angle of the adjusted thin iron sheet; when installing and fixing the thin iron sheet, due to the lack of effective limiting measures, the thin iron sheet is very likely to move, making the entire welding process unstable, further increasing the difficulty and uncertainty of the welding operation; this unstable welding state not only reduces production efficiency, but also requires operators to spend a lot of time and energy on repeated adjustments and corrections, increasing labor costs and production costs.

[0004] The authorization publication number "CN112139652A" records an ultrasonic welding device with a positioning structure, which relates to the technical field of ultrasonic welding devices, specifically a processing platform and an electric telescopic rod, wherein a clamping and fixing mechanism is arranged on the surface of the processing platform, a double slide rail is arranged on the top of the fixed support rod, a cylinder is fixed on the top of the sliding plate, an ultrasonic generator is connected to the bottom of the double slide rail, a welding head is connected to the bottom of the amplitude rod, a laser transmitter is fixed inside the push rod, and the electric telescopic rod is connected to the side of the cylinder. The ultrasonic welding device with a positioning structure can adjust the spacing between the fixed pressing plate and the movable pressing plate by rotating the rotating handle clockwise or counterclockwise, so as to facilitate adapting to workpieces of different widths, and the fixed pressing plate and the movable pressing plate can be heightened by inserting the plug at the bottom of the heightening pressing plate into the slot on the top surface of the movable pressing plate and the fixed pressing plate, so as to facilitate adapting to workpieces of different heights.

[0005] The above patent can adjust the spacing between the fixed pressure plate and the movable pressure plate by rotating the handle clockwise or counterclockwise, so as to adapt to workpieces of different widths, and the fixed pressure plate and the movable pressure plate can be raised by inserting the plug at the bottom of the raised pressure plate into the slot on the top surface of the movable pressure plate and the fixed pressure plate, so as to adapt to workpieces of different heights. However, the above patent has certain limitations when used. The current equipment cannot adjust the angle of the welding thin iron interface according to actual needs, and it is difficult to adjust the position of the thin iron sheet, which greatly affects the control of the gap between the thin iron sheets during welding. In addition, the equipment cannot perform adaptive elastic limiting according to the adjusted angle of the thin iron sheet, resulting in poor stability of the thin iron sheet during installation and fixation, and it is very easy to move.

[0034] The device for welding thin iron surfaces using any of the above mentioned devices is characterized in that it comprises the following steps:

[0035] S1. Positioning of thin iron sheet: Start the third motor, and its output end drives the first screw to rotate. Since the two second nuts are threadedly connected to the first screw in opposite directions, when the screw rotates, the two second nuts move toward or away from each other along the axial direction. The rotation direction of the first screw is controlled to make the second nuts move toward each other, driving the two moving plates fixed on the circumferential surface thereof to approach each other. The moving plates gradually come close to the two sides of the thin iron sheet located at the lower side. By accurately controlling the rotation angle and number of turns of the first screw, the spacing between the moving plates is accurately adjusted to match the size of the thin iron sheet, and the thin iron sheet is stably clamped in an ideal position, providing a stable foundation for subsequent operations.

[0036] S2. Adjustment of the angle of the thin iron sheet: start the first motor, and its output end drives the driving rod to rotate, and the driving gear on the circumferential surface of the driving rod rotates accordingly, and the driving gear meshes with the transmission gear, driving the rotating rod to rotate, thereby realizing the adjustment of the angle of the thin iron sheet. During the adjustment process, the anti-slip pressure block in contact with the thin iron sheet is subjected to external force due to the change in the position of the thin iron sheet. The anti-slip pressure block is connected to the second pressure plate through the second spring. The second spring expands and contracts according to the external force exerted on the anti-slip pressure block, and adaptively adjusts the pressure of the anti-slip pressure block on the thin iron sheet to maintain stable clamping. At the same time, the sliding rod slides in the arc-shaped connecting sleeve, and its position change causes the connected arc-shaped sliding block to slide in the arc-shaped connecting sleeve. The first spring connecting the arc-shaped sliding block and the inner wall of the arc-shaped connecting sleeve is compressed or stretched accordingly, generating elastic force, which further stably clamps the thin iron sheet, ensuring that the thin iron sheet is stable and not damaged during the angle adjustment;

[0037] S3, fine-tuning and monitoring the position of the thin iron sheet: when the position of the thin iron sheet needs to be adjusted or fixed, the cylinder is started, and its telescopic end drives the plastic pad to contact the thin iron sheet. The plastic pad contacts in a soft manner to avoid damaging the thin iron sheet, while providing a stable thrust or pull. The infrared sensor at the near end of the connecting platform monitors the position state of the thin iron sheet, which is electrically connected to the third motor. If the position of the thin iron sheet deviates, the infrared sensor feeds back a signal to the control system, and the control system controls the third motor to adjust the rotation of the first screw rod, driving the moving plate to fine-tune the position of the thin iron sheet to ensure that the thin iron sheet is always in an ideal position;

[0038] S4. Welding operation: After the thin iron sheet is positioned and the angle is adjusted, the intelligent laser welding head performs laser welding on the joint interface of the thin iron sheet according to the preset parameters and procedures. The intelligent laser welding head accurately controls the welding power, welding speed, welding path, etc. to ensure the welding quality. During the welding process, the elastic clamping mechanism continues to play a role to prevent the thin iron sheet from being displaced due to external forces such as vibration and thermal stress during welding, ensuring the stability of the welding process.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. In this scheme, the adjustment mechanism is provided with two groups, each of which is used to adjust the angle of the two thin iron sheets. The first motor drives the driving rod to rotate, and the driving gear on the driving rod meshes with the transmission gear to drive the rotating rod to rotate, so as to adjust the angle of the thin iron sheet. At the same time, the third motor drives the first screw rod to rotate, so that the second nut threadedly connected thereto drives the moving plate to move toward or away from each other, thereby accurately adjusting the position of the thin iron sheet at the lower side.

[0041] It can flexibly and accurately adjust the thin iron interface angle and the thin iron sheet position according to actual welding needs, effectively control the gap between the thin iron sheets during welding, ensure uniform weld filling, improve the strength of the weld joint, reduce the burn-through phenomenon of thin iron materials, improve product quality, reduce scrap rate, and improve production efficiency.

[0042] 2. In this scheme, an elastic clamping mechanism is provided, which has two groups for elastically clamping two thin iron sheets. When adjusting the angle of the thin iron sheet, the anti-slip pressure block in contact with the thin iron sheet is connected to the second pressure plate through the second spring. The second spring expands and contracts according to the external force on the anti-slip pressure block, and adaptively adjusts the pressure of the anti-slip pressure block on the thin iron sheet. At the same time, the sliding rod slides in the arc-shaped connecting sleeve, driving the arc-shaped slider to slide, so that the first spring is compressed or stretched accordingly, generating elastic force, and further stably clamping the thin iron sheet;

[0043] During the thin iron sheet angle adjustment and welding process, elastic limiting can be adaptively performed according to the angle change of the thin iron sheet to ensure that the thin iron sheet will not be displaced, thereby improving the stability of welding, reducing the workload of operators to repeatedly adjust the thin iron sheet, reducing labor costs, avoiding product damage caused by the displacement of the thin iron sheet, reducing production costs, and ensuring the reliability of welding quality.

DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Example 1

[0055] See also Figure 1-Figure 7 , the present invention provides the following technical solutions:

[0056] A device for welding thin iron surface interfaces, comprising:

[0057] A welding table 2, wherein the top of the welding table 2 is fixedly connected to two connecting platforms 1, a limiting groove 201 is provided at the top of the welding table 2, two arc-shaped connecting sleeves 5 are fixedly connected to the two connecting platforms 1, two sliding rods 12 are slidably connected to the four arc-shaped connecting sleeves 5, a second motor 13 is fixedly connected to one side end of the connecting platform 1, two thin iron sheets 9 are provided in the two connecting platforms 1, a driving rod 32 and two rotating rods 19 are rotatably connected in the two connecting platforms 1, and two driving gears 22 are fixedly connected to the circumferential surface of the driving rod 32;

[0058] An intelligent laser welding head 26, which is disposed between the two connection platforms 1; and

[0059] The adjusting mechanism is provided with two groups, and the two groups of adjusting mechanisms are used to adjust the angles of the two thin iron sheets 9 respectively;

[0060] The elastic clamping mechanism is provided with two groups, and the two groups of elastic clamping mechanisms are arranged in the two connecting platforms 1, and the two groups of elastic clamping mechanisms are used to elastically clamp the two thin iron sheets 9.

[0061] In a specific embodiment of the present invention, the connecting platform 1 is mainly used to install and fix key components such as the arc-shaped connecting sleeve 5, the second motor 13, the driving rod 32, the rotating rod 19, and provide a space for placing and installing the thin iron sheet 9. The connecting platform 1 works in coordination with other components to achieve driving, adjustment and fixation of the thin iron sheet 9.

[0062] The arc-shaped connecting sleeve 5 cooperates with the sliding rod 12, allowing the sliding rod 12 to slide inside it. This sliding connection mode provides freedom for the movement of subsequent related components, and is used to achieve certain adjustment or transmission functions, such as angle adjustment or position adjustment of the auxiliary thin iron sheet 9.

[0063] The sliding rod 12 slides in the arc-shaped connecting sleeve 5, and transmits power or realizes the change of position through the connection with other parts. It is associated with the adjustment mechanism of the thin iron sheet 9, and under the action of the elastic clamping mechanism parts, drives the thin iron sheet 9 to adjust the angle or position.

[0064] The first motor 6 is used as a power source to provide power for some moving parts of the welding device. The first motor 6 rotates to drive the driving rod 32 and then cooperates with the adjustment mechanism to drive the thin iron sheet 9, thereby adjusting the angle or position of the thin iron sheet 9;

[0065] The second motor 13 is used as a power source to drive the second screw rod 25 to rotate.

[0066] The thin iron sheet 9 is the core processing component of the entire welding device as the object of welding. The angle and position are adjusted by the driving and adjusting mechanism in the connecting table 1 to meet different welding requirements, and finally the welding is completed under the action of the intelligent laser welding head 26.

[0067] The driving rod 32 cooperates with other gears or rack structures through two driving gears 22 fixedly connected by the circumferential surface to realize the transmission of power and the conversion of motion forms. Driven by the motor, the driving rod 32 rotates, driving the driving gear 22 to rotate, and then drives other parts meshing therewith to move, so as to adjust the angle of the thin iron sheet 9.

[0068] The driving gear 22 serves as a transmission component, converting the rotation of the driving rod 32 into the rotation of the transmission gear 20. By meshing with the transmission gear 20, the transmission of force and the change of the direction of movement are achieved, thereby adjusting the thin iron sheet 9.

[0069] As the welding execution component, the intelligent laser welding head 26 can accurately perform laser welding on the interface of the thin iron sheet 9 according to the preset parameters and procedures. Through intelligent control, accurate control of the welding process is achieved, including welding power, welding speed, welding path, etc., so as to ensure welding quality.

[0070] The adjusting mechanism is used to accurately adjust the angle of the thin iron sheet 9 according to the welding requirements. By working in coordination with the sliding rod 12, the driving rod 32, the rotating rod 19 and other components, the angle of the thin iron sheet 9 can be flexibly adjusted to ensure that the thin iron sheet 9 is at the best angle during welding, so as to ensure the uniformity of the welding gap and the welding quality.

[0071] The elastic clamping mechanism is used to elastically clamp the thin iron sheet 9. In the process of adjusting the angle of the thin iron sheet 9, it can adaptively perform elastic limiting according to the angle change of the thin iron sheet 9. On the one hand, it ensures that the thin iron sheet 9 will not be displaced during the welding process, thereby improving the stability of welding; on the other hand, when adjusting the angle of the thin iron sheet 9, it can provide a certain elastic buffer to avoid damage to the thin iron sheet 9, and also help to achieve accurate angle adjustment.

[0072] For details, please refer to Figure 1-Figure 7 , where a set of regulatory mechanisms includes:

[0073] Transmission gear 20, two transmission gears 20 are provided, and the two transmission gears 20 are fixedly connected to the circumferential surface of one of the rotating rods 19;

[0074] The arc-shaped cover plates 18 are provided with two arc-shaped cover plates 18 , and the two arc-shaped cover plates 18 are fixedly connected to the circumferential surface of one of the rotating rods 19 .

[0075] In this embodiment: two transmission gears 20 are fixedly connected to the circumferential surface of the rotating rod 19, and their core function is power transmission and conversion. The rotating rod 19 starts to rotate under the drive of the first motor 6 or other power sources, and the transmission gear 20 rotates synchronously therewith, and the arc cover plate 18 rotates together with the two rotating rods 19. The two arc cover plates 18 are respectively used to support the two thin iron sheets 9 to be welded, so that the welding is more stable. The main function of the two arc cover plates 18 is to provide a stable support surface for the thin iron sheet 9.

[0076] For details, please refer to Figure 1-Figure 3 , wherein a set of elastic clamping mechanisms includes:

[0077] The arc-shaped rod 16 is provided with two arc-shaped rods 16, and the two arc-shaped rods 16 are respectively fixedly connected to the inner walls of two sides of the two arc-shaped connecting sleeves 5;

[0078] The arc-shaped slider 14 is provided with two arc-shaped sliders 14, and the two arc-shaped sliders 14 are respectively slidably connected in two of the arc-shaped connecting sleeves 5.

[0079] The first spring 15 is provided with two first springs 15, one end of the two first springs 15 is respectively fixedly connected to one side inner wall of two arc-shaped connecting sleeves 5, and the other end of the two arc-shaped connecting sleeves 5 is respectively fixedly connected to the top of the two arc-shaped sliders 14;

[0080] A second pressing plate 30, the second pressing plate 30 is fixedly connected to the circumferential surface of one of the sliding rods 12;

[0081] A first pressing plate 17, wherein two first pressing plates 17 are provided, and the two first pressing plates 17 are fixedly connected to both ends of the second pressing plate 30;

[0082] Anti-skid pressing blocks 28, four anti-skid pressing blocks 28 are provided, and the four anti-skid pressing blocks 28 are all provided on one side of the second pressing plate 30;

[0083] A second spring 29, wherein four second springs 29 are provided, and the four second springs 29 are respectively fixedly connected to the second pressing plate 30 and the adjacent ends of the four anti-slip pressing blocks 28, and one side of the four anti-slip pressing blocks 28 is closely attached to one side of one of the thin iron sheets 9;

[0084] The positioning component is arranged in the limiting groove 201 and is used for positioning the thin iron sheet 9 .

[0085] In this embodiment: when the thin iron sheet 9 needs to be welded, the positioning component starts working first, and the thin iron sheet 9 is accurately positioned in the limiting groove 201 to determine its ideal position and angle during the welding process. Subsequently, the elastic clamping mechanism begins to play a role. As the adjustment of the angle of the thin iron sheet 9 is achieved through the adjustment mechanism, the anti-skid pressure block 28 in contact with the thin iron sheet 9 will be subjected to external force due to the change in the position of the thin iron sheet 9. The anti-skid pressure block 28 is connected to the second pressure plate 30 through the second spring 29. The second spring 29 will expand and contract according to the size of the external force applied to the anti-skid pressure block 28, thereby adaptively adjusting the pressure of the anti-skid pressure block 28 on the thin iron sheet 9, and always maintaining a stable clamping of the thin iron sheet 9.

[0086] At the same time, the second pressing plate 30 is fixed on the sliding rod 12, and the sliding rod 12 slides in the arc-shaped connecting sleeve 5. When the angle of the thin iron sheet 9 changes, causing the position of the sliding rod 12 to change, the arc-shaped slider 14 connected thereto will also slide in the arc-shaped connecting sleeve 5. At this time, the first spring 15 connecting the arc-shaped slider 14 and the inner wall of the arc-shaped connecting sleeve 5 will be compressed or stretched accordingly, generating elastic force, further providing a stable clamping force for the thin iron sheet 9. The first pressing plate 17 expands the clamping area to ensure that the clamping force is evenly distributed on the edge of the thin iron sheet 9. The entire elastic clamping mechanism works in coordination, and during the process of adjusting the angle of the thin iron sheet 9, the thin iron sheet 9 is always kept stably clamped to prevent its displacement, thereby providing stable working conditions for the welding process.

[0087] For details, please refer to Figure 2 , the positioning components include:

[0088] A first screw rod 3, the first screw rod 3 is rotatably connected to the inner walls of both sides of the limiting groove 201;

[0089] A second nut 33, wherein two second nuts 33 are provided, and both second nuts 33 are threadedly connected to the circumferential surface of the first screw rod 3;

[0090] The movable plate 27 is provided with two parts, and the two movable plates 27 are respectively fixedly connected to the circumferential surface of the second nut 33, and the close ends of the two movable plates 27 are used to tightly clamp the two sides of one of the thin iron sheets 9 located on the lower side.

[0091] In this embodiment, when the thin iron sheet 9 located at the lower side needs to be positioned, the first screw rod 3 is first rotated by the power of the third motor 31. Since the two second nuts 33 are threadedly connected to the first screw rod 3 in opposite directions, as the first screw rod 3 rotates, the two second nuts 33 move toward or away from each other along the axial direction of the screw rod.

[0092] When it is necessary to position the thin iron sheet 9, the rotation direction of the first screw rod 3 is controlled to make the two second nuts 33 move toward each other. At this time, the two movable plates 27 fixed on the circumferential surface of the second nuts 33 will also move toward each other. As the movable plates 27 approach, their adjacent ends gradually cling to both sides of the thin iron sheet 9. By accurately controlling the rotation angle and number of turns of the first screw rod 3, the distance between the two movable plates 27 can be accurately adjusted to accurately match the size of the thin iron sheet 9, thereby stably clamping the thin iron sheet 9 in an ideal position. During the welding process, even if the thin iron sheet 9 is subjected to external forces such as vibration and thermal stress during welding, due to the tight clamping of the movable plates 27, the thin iron sheet 9 can also be maintained at the initial positioning position, providing a stable foundation for subsequent elastic clamping and welding work, ensuring the smooth progress of the welding process and the reliability of the welding quality.

[0093] For details, please refer to Figure 1-Figure 7 The top ends of the two connecting platforms 1 are fixedly connected with a connecting plate 7, two cylinders 8 are fixedly connected inside the connecting plate 7, a second screw rod 25 is rotatably connected inside the two connecting platforms 1, a first nut 24 is threadedly connected to the circumferential surface of the second screw rod 25, and a movable sleeve plate 23 is fixedly connected to the circumferential surface of the first nut 24.

[0094] In this embodiment: the connecting plate 7 serves to connect and integrate the two connecting platforms 1, thereby enhancing the stability and integrity of the entire structure. At the same time, it provides an installation foundation for the cylinder 8, which is fixed in the connecting plate 7. When the telescopic end of the cylinder 8 expands, it drives the plastic pad 21 to limit the thin iron sheet 9, and the second screw rod 25 can drive the first nut 24 threadedly connected thereto to move along the axial direction of the second screw rod 25. Since the second screw rod 25 has a precise pitch, the moving distance and speed of the first nut 24 can be precisely controlled, thereby realizing precise position adjustment of the components connected to the first nut 24.

[0095] For details, please refer to Figure 1-Figure 3The telescopic ends of the two cylinders 8 are fixedly connected with plastic pads 21, and the close ends of the two connecting platforms 1 are fixedly connected with infrared sensors 34.

[0096] In this embodiment, when the thin iron sheet 9 needs to be adjusted or fixed, the cylinder 8 extends, and the plastic pad 21 can contact the thin iron sheet 9 in a relatively soft manner to avoid hard contact and damage to the thin iron sheet 9, while providing a stable thrust or pull. The infrared sensor 34 fixed at the near end of the connecting platform 1 is used to monitor the position state of the thin iron sheet 9, and the infrared sensor 34 is electrically connected to the third motor 31.

[0097] For details, please refer to Figure 1-Figure 7 The far ends of the two sliding rods 12 are fixedly connected to the limit plates 4, and the far ends of the two limit plates 4 are provided with threaded holes. The bottom end of the welding table 2 is fixedly connected to two support seats 11.

[0098] In this embodiment: when the sliding rod 12 moves during the operation of adjusting the angle or position of the thin iron sheet 9, if it is about to exceed the reasonable range, the threaded hole provided on the limit plate 4 can be used to connect other auxiliary components or to install and fix the equipment to prevent the sliding rod 12 from moving further;

[0099] The two support seats 11 provide stable support for the entire welding device, ensuring that the device is placed stably, so that the sliding rod 12 and other components will not be affected by the shaking of the device during operation, ensuring that the adjustment and welding operations of the thin iron sheet 9 can be carried out stably.

[0100] For details, please refer to Figure 1-Figure 7 One side end of a connecting table 1 is fixedly connected to a first motor 6, and the output end of the first motor 6 is fixedly connected to the circumferential surface of a driving rod 32. One side end of a welding table 2 is fixedly connected to a third motor 31, and the output end of the third motor 31 is fixedly connected to the circumferential surface of the first screw rod 3.

[0101] In this embodiment: the first motor 6 is fixed to one side end of one of the connection tables 1, and its output end is connected to the circumferential surface of the driving rod 32. When the first motor 6 is started, it will drive the driving rod 32 to rotate, and the driving gear 22 fixed to the circumferential surface of the driving rod 32 will rotate accordingly, thereby driving the transmission gear 20 and the rotating rod 19 and other components meshed therewith to move, thereby adjusting the angle of the thin iron sheet 9. The third motor 31 is fixed to one side end of the welding table 2, and its output end is connected to the first screw rod 3. When it is necessary to position the thin iron sheet 9, the third motor 31 is started, driving the first screw rod 3 to rotate, so that the second nut 33 threadedly connected to the first screw rod 3 drives the moving plate 27 to move, thereby positioning and clamping the thin iron sheet 9. In the actual welding process, according to the welding process requirements, the start, stop and speed of the first motor 6 and the third motor 31 can be flexibly controlled to accurately adjust the angle and position of the thin iron sheet 9 to meet the needs of different welding scenes.

[0102] For details, please refer to Figure 1-Figure 3 The adjacent ends of the two connecting platforms 1 are fixedly connected to the limiting sleeve 10, and the movable sleeve plate 23 is slidably connected in the limiting sleeve 10.

[0103] In this embodiment, the limiting sleeves 10 fixed at the near ends of the two connecting platforms 1 provide a sliding track for the movable sleeve plate 23. The movable sleeve plate 23 slides in the limiting sleeve 10, so that the movement of the movable sleeve plate 23 is more stable and the direction is controllable. When the first nut 24 moves under the drive of the second screw rod 25, the movable sleeve plate 23 fixedly connected thereto will move in the limiting sleeve 10 along a predetermined direction.

[0104] Working principle and use process of the present invention: When the welding device is working, the thin iron sheet 9 is first positioned by using the positioning assembly. The third motor 31 is started, which drives the first screw rod 3 to rotate. Since the two second nuts 33 are threadedly connected to the first screw rod 3 in opposite directions, the second nuts 33 drive the moving plate 27 to move toward or away from each other. By controlling the rotation of the first screw rod 3, the close ends of the moving plates 27 are closely attached to the two sides of the lower thin iron sheet 9, and the spacing between the moving plates 27 is accurately adjusted to stably clamp the thin iron sheet 9 in an ideal position.

[0105] Then, the angle of the thin iron sheet 9 is adjusted. The first motor 6 is started, which drives the driving rod 32 to rotate, and the driving gear 22 on the driving rod 32 rotates accordingly. The driving gear 22 meshes with the transmission gear 20, and then drives the rotating rod 19 to rotate, so as to adjust the angle of the thin iron sheet 9. In this process, the anti-skid pressure block 28 in contact with the thin iron sheet 9 is subjected to external force due to the change in the position of the thin iron sheet 9. The anti-skid pressure block 28 is connected to the second pressure plate 30 through the second spring 29. The second spring 29 expands and contracts according to the external force on the anti-skid pressure block 28, and adaptively adjusts the pressure of the anti-skid pressure block 28 on the thin iron sheet 9. At the same time, the sliding rod 12 slides in the arc-shaped connecting sleeve 5, driving the arc-shaped slider 14 connected thereto to slide, so that the first spring 15 is compressed or stretched accordingly, and the elastic force is generated to further stably clamp the thin iron sheet 9, ensuring that the thin iron sheet 9 is stable and not damaged when the angle is adjusted.

[0106] During the positioning and angle adjustment of the thin iron sheet 9, if the position of the thin iron sheet 9 needs to be fine-tuned, the cylinder 8 can be started, and the plastic pad 21 at the telescopic end of the cylinder 8 contacts the thin iron sheet 9 in a soft manner to provide a stable thrust or pull. The infrared sensor 34 at the near end of the connecting platform 1 monitors the position state of the thin iron sheet 9 in real time. If the position deviates, the infrared sensor 34 feeds back the signal to the control system, and the control system controls the third motor 31 to adjust the rotation of the first screw rod 3, driving the moving plate 27 to loosen the position of the thin iron sheet 9, and then the elastic clamping mechanism will fit the thin iron sheet 9 tightly, so that the thin iron sheet 9 can achieve fine adjustment.

[0107] After the thin iron sheet 9 is positioned and the angle is adjusted, the intelligent laser welding head 26 performs laser welding on the interface of the thin iron sheet 9 according to the preset parameters and procedures. During the welding process, the elastic clamping mechanism continues to play a role to prevent the thin iron sheet 9 from being displaced due to external forces such as vibration and thermal stress during welding, thereby ensuring the welding quality until the welding work is completed.

[0108] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.

Positioning the thin iron sheet: start the third motor (31), and its output end drives the first screw rod (3) to rotate.
