Description

Technical Field

[0001] This invention relates to the field of thermos cup manufacturing technology, and in particular to a positioning laser welding device for thermos cups to prevent thin-walled deformation. Background Technology

[0002] Laser welding, as a high-energy-density welding method, has advantages such as a small heat-affected zone, fast welding speed, narrow weld seam, and beautiful weld formation. It has been widely used in many fields such as aerospace, automobile manufacturing, pressure vessels, and civilian products. In the manufacturing process of stainless steel thermos cups, laser welding is particularly suitable for precision welding of thin-walled cups due to its concentrated energy and small thermal deformation. However, laser welding of thin-walled thermos cups still faces technical challenges in engineering practice, mainly manifested in insufficient positioning accuracy during the welding process and imperfections in subsequent sealing tests.

[0003] In the manufacturing process of thermos cups, welding is one of the key processes that determines product quality. It mainly includes longitudinal seam welding of the cup body, circumferential seam welding of the cup bottom and body, and cup rim welding. Precise positioning and clamping before welding are crucial to ensuring welding quality. Thin-walled cups are prone to elliptical deformation or local depressions during clamping due to uneven clamping force, causing the weld trajectory to deviate from the theoretical position. Moreover, the concentric positioning accuracy directly affects the welding quality of the equipment. If the positioning deviation is too large, it can further affect the continuity and consistency of the weld. Furthermore, local gaps are prone to occur during the welding process, which will seriously damage the strength and sealing of the weld. Therefore, a laser welding equipment for positioning thermos cups to prevent thin-walled deformation is proposed. Summary of the Invention

[0004] This invention addresses the issues of welding quality and product qualification rate during the welding process by providing a laser welding device for positioning thermos cups to prevent thin-walled deformation.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a laser welding device for positioning thermos cups to prevent thin-wall deformation, including a worktable and a fixed bed frame, wherein the fixed bed frame is installed on the worktable, and the worktable also includes a limiting mechanism, a docking mechanism and a welding mechanism; The limiting mechanism includes a transmission disk, a rotating disk, and several clamping frames. The transmission disk is mounted on a fixed bed frame, the rotating disk is rotatably disposed on one side of the transmission disk, and the clamping frames are evenly distributed on one side of the rotating disk for limiting and clamping cylindrical cup bodies. The docking mechanism includes a fixed slide rail and a movable frame. The fixed slide rail is installed on the top of the fixed bed frame, and the movable frame is movably disposed on the top of the fixed slide rail. The movable frame is provided with a positioning frame for limiting the bottom of the cup. The welding mechanism includes a conveyor frame installed inside a fixed bed frame. Welding components are mounted on the conveyor frame. Through the uniform expansion clamping of the clamping frame and buffer plate in the limiting mechanism, combined with airflow detection of the sealing ring frame and coaxiality detection of the movable rollers on the extension plate in the docking mechanism, integrated anti-deformation processing from clamping, welding to inspection is achieved. Simultaneously, post-weld processing is performed using a grinding end block, and the buffer plate is vibrated and chip removed by a moving plate. Overall, this equipment effectively improves the welding quality and yield of thin-walled thermos cups, and optimizes operational convenience with a movable control panel.

[0006] A further preferred embodiment of the present invention is as follows: a support plate is installed at the top of the fixed bed frame, and a control panel is movably arranged on the support plate. The control panel is used by the operator to control the operation of the equipment. The movable and adjustable control panel improves the ease of operation, realizes one-handed control of the equipment operation, and optimizes the human-computer interaction experience.

[0007] A further preferred embodiment of the present invention is as follows: a fixed shaft is mounted on the rotating disk, a plurality of guide rail plates are mounted on the fixed shaft, a docking plate is mounted on one end of the fixed shaft, a plurality of movable grooves are opened on the docking plate, and a telescopic shaft is movably arranged inside the movable grooves. A support roller is rotatably arranged on the movable end of the telescopic shaft, and the support roller abuts against the inclined guide rail plate. A guide rail plate is mounted on the outside of the docking plate, and a clamping frame is movably inserted between the guide rail plate and the docking plate. The clamping frame is in an inward tightening state, and the bottom surface of the clamping frame abuts against the support roller. It is used to control the movement of the clamping frame at the top by means of the telescopic shaft. By utilizing the cooperation of the guide rail plate and the support roller, the linear movement of the telescopic shaft is converted into the radial expansion of the clamping frame, thereby achieving uniform pressing and reliable limiting of the cylindrical cup body.

[0008] A further preferred embodiment of the present invention is as follows: a buffer pad is installed on the top of the clamping frame, the buffer pad is used to abut against the inside of the cylindrical cup body, and a support frame is provided inside the buffer pad. With the help of the elastic buffer pad with the support frame, the contact area with the thin-walled cup body is increased, effectively reducing the risk of cup body deformation caused by clamping force.

[0009] A further preferred embodiment of the present invention is as follows: a fixing groove is provided at one end of the clamping frame located at the bottom of the buffer pad, and an elastic actuating plate is connected inside the fixing groove. The actuating plate can abut against the support roller. As the support roller rotates, it drives the actuating plate at the top to move with the buffer pad, reducing the situation of debris residue. By rotating the support roller to actuate the actuating plate, the buffer pad generates micro-vibration, automatically shaking off the debris remaining on the clamping surface, ensuring the cleanliness of clamping and avoiding affecting subsequent processes.

[0010] A further preferred embodiment of the present invention is as follows: a connecting frame is installed on the movable frame, the connecting frame is vertically bent, an adjusting plate is movably arranged on the connecting frame, a positioning frame is installed at the rear end of the adjusting plate, a set of movable end blocks are provided at both ends of the positioning frame, and an extension plate for auxiliary positioning and pressing is provided on the outside of the movable end blocks. The rollers on the extension plates are controlled by the movable end blocks to press against the cup body, thereby realizing auxiliary pressing and position detection at the docking point, reducing docking offset, and ensuring positional accuracy before welding.

[0011] A further preferred embodiment of the present invention is as follows: a positioning plate is provided on the side of the connecting frame near the limiting mechanism, a limiting suction cup is installed inside the positioning plate, a sealing ring frame is movably sleeved on the outside of the positioning plate, the sealing ring frame is used to press against the outside of the cup bottom, and a plurality of arc-shaped sealing strips are provided inside the sealing ring frame; The rotating disk is connected to a conveying pipe, and a sealing gasket is installed on the side of the rotating disk near the fixed shaft. Several conveying holes are opened on the sealing gasket, and the rotating disk has conveying holes corresponding to the positions of the conveying holes. The air supply holes are connected to the conveying pipe. After welding, the sealing ring frame fits the welding area and vents air into the cup body. The built-in airflow sensing module provides feedback on the welding sealing performance, realizing real-time detection of welding quality and reducing the defect rate.

[0012] A further preferred embodiment of the present invention is as follows: a telescopic component is provided on the outside of the movable end block, and an extension plate is connected to the outside of the telescopic component. A set of conveying grooves is opened on the movable end of the extension plate, and a set of detection frames is movably arranged inside the conveying grooves. Adjustable snap-fit ​​frames are provided at both ends of the detection frames, and a set of movable rollers is provided on the snap-fit ​​frames. Pressure sensing modules are provided inside the movable rollers. By setting movable rollers with pressure sensing modules on both sides of the weld, automatic detection of the coaxiality of the cup body after welding is realized, which facilitates the screening out of defective products that are deformed or misaligned.

[0013] A further preferred embodiment of the present invention is as follows: a grinding end block is provided on the movable end of the extension plate, and conductive arc surfaces are provided at both ends of the grinding end block. A snap-fit ​​groove is provided on the grinding end block, and a grinding plate is installed inside the snap-fit ​​groove. A round shaft is provided in the middle section of the detection frame, and the round shaft is used to snap onto the conductive arc surface to control the grinding end block to be pulled outward. After coaxiality detection, the grinding end block is driven to extend outward and fit against the cup wall by the inward movement of the detection frame, thereby realizing automatic grinding of the welding area, effectively removing welding slag and improving surface quality.

[0014] A further preferred embodiment of the present invention is as follows: a transmission guide rail is movably arranged on the conveyor frame, and a mounting plate is movably arranged on the transmission guide rail. The welding assembly is mounted on the mounting plate. With the help of the transmission guide rail and the mounting plate, the welding assembly can be accurately moved and positioned at the connection point of the cup body, providing a motion basis for performing high-quality laser welding.

[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. This invention utilizes an airflow sensing module within the sealing ring frame of the docking mechanism to deliver airflow into the cup body after welding to provide feedback on airtightness. Simultaneously, a pressure sensing module installed inside a set of movable rollers on the extension plate can perform coaxiality detection on both sides of the weld, effectively screening out defective products and realizing online airtightness and coaxiality detection of welding quality.

[0016] 2. The present invention uses a clamping frame and a buffer pad evenly distributed on a rotating disk. With the help of the telescopic shaft and the inclined guide plate, the clamping frame expands outward evenly. Combined with the large-area support of the elastic buffer pad, the stress concentration and deformation risk of the thin-walled cylinder during the welding process are significantly reduced, and the welding deformation of the thin-walled cup body is effectively suppressed.

[0017] 3. The grinding end block on the extension plate of the present invention can be moved outward to fit the cup wall after inspection to grind the weld seam to reduce welding slag. At the same time, during reset, the support roller moves the moving plate, which drives the buffer pad to continuously move and shake off the debris to ensure the cleanliness of the clamping.

[0018] 4. The control panel on the support plate of this invention is movable, allowing operators to adjust its position according to their habits during use, which facilitates one-handed control of the equipment's operation, optimizes the human-computer interaction experience, and improves the flexibility and convenience of equipment operation.

Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes the title of the laser welding equipment for positioning thermos cups to prevent thin-walled deformation. Please refer to [link / reference]. Figures 1-10 Specifically, the following is a laser welding device for positioning thermos cups to prevent thin-walled deformation, including a worktable 1 and a fixed bed frame 11. The fixed bed frame 11 is installed on the worktable 1, and the worktable 1 also includes a limiting mechanism, a docking mechanism and a welding mechanism. The limiting mechanism includes a transmission disk 2, a rotating disk 21, and several clamping frames 26. The transmission disk 2 is mounted on the fixed bed frame 11. The rotating disk 21 is rotatably disposed on one side of the transmission disk 2. The clamping frames 26 are evenly distributed on one side of the rotating disk 21 and are used for limiting and clamping cylindrical cups. The docking mechanism includes a fixed slide rail 3 and a movable frame 31. The fixed slide rail 3 is installed on the top of the fixed bed frame 11, and the movable frame 31 is movably set on the top of the fixed slide rail 3. The movable frame 31 is provided with a positioning frame 35 for limiting the bottom of the cup. The welding mechanism includes a conveyor frame 4, which is installed inside the fixed bed frame 11. Welding components are mounted on the conveyor frame 4. Through the uniform expansion clamping of the clamping frame 26 and the buffer plate 261 in the limiting mechanism, combined with the airflow detection of the sealing ring frame 34 in the docking mechanism and the coaxiality detection of the movable roller 391 on the extension plate 37, integrated anti-deformation processing from clamping, welding to inspection is achieved. Simultaneously, post-weld processing is performed using the grinding end block 38, and the buffer plate 261 is vibrated and chip removed by the actuating plate 28. Overall, this equipment effectively improves the welding quality and yield of thin-walled thermos cups, and optimizes operational convenience with the movable control panel 13.

[0025] like Figure 1 and Figure 2 As shown, a support plate 12 is installed at the top of the fixed bed frame 11, and a control panel 13 is movably installed on the support plate 12. The control panel 13 is used by the operator to control the operation of the equipment. The position of the control panel 13 can be adjusted during use to facilitate one-handed control of the equipment's operating status during subsequent operations.

[0026] like Figure 2 and Figure 4 As shown, a fixed shaft 23 is mounted on the rotating disk 21, and several guide rails 231 are mounted on the fixed shaft 23. A docking disk 24 is mounted on one end of the fixed shaft 23. Several movable slots are provided on the docking disk 24, and a telescopic shaft 27 is movably arranged inside the movable slots. A support roller 271 is rotatably arranged on the movable end of the telescopic shaft 27. The support roller 271 abuts against the inclined guide rails 231. A guide rail plate 25 is mounted on the outside of the docking disk 24, and a clamping frame 26 is movably inserted between the guide rail plate 25 and the docking disk 24. Between the discs 24, the clamping frame 26 is in an inward tightening state, with the bottom surface of the clamping frame 26 abutting against the support roller 271. It is used to control the movement of the clamping frame 26 at the top via the telescopic shaft 27. During the operation of the equipment, it can keep the cylindrical cup body outside the clamping frame 26. As the movable end of the telescopic shaft 27 moves, it can cooperate with the inclined guide plate 231 and the support roller 271 to drive the clamping frame 26 at the top to expand outward, thereby pressing and limiting the cylindrical cup body.

[0027] like Figure 7 As shown, a buffer plate 261 is installed on the top of the clamping frame 26. The buffer plate 261 is used to abut against the inside of the cylindrical cup body. A support frame is provided inside the buffer plate 261. With the help of the buffer plate 261, it can abut against the inside of the cylindrical cup body. With the help of the elastic buffer plate 261, the overall contact area can be increased. Compared with the traditional clamping mechanism, it can reduce the deformation of the thin-walled cup body.

[0028] like Figure 7As shown, the clamping frame 26 has a fixing groove at one end of the bottom of the buffer pad 261, and an elastic actuating plate 28 is connected inside the fixing groove. The actuating plate 28 can abut against the support roller 271. As the support roller 271 rotates, it drives the top actuating plate 28 and the buffer pad 261 to move, reducing the residue of debris. When the clamping frame 26 returns to the bottom, the support roller 271 can abut against the bottom of the actuating plate 28. As the support roller 271 rotates, it can drive the actuating plate 28 and the top buffer pad 261 to move continuously, which can shake off the remaining debris and reduce the residue during the clamping process.

[0029] like Figure 8 and Figure 9 As shown, a connecting frame 32 is installed on the movable frame 31. The connecting frame 32 is vertically bent and has an adjustable plate movably mounted on it. A positioning frame 35 is installed at the rear end of the adjustable plate. A set of movable end blocks 36 are provided at both ends of the positioning frame 35. An extension plate 37 for auxiliary positioning and clamping is provided outside the movable end blocks 36. By controlling the movement of the external adjusting plate with the movable end blocks 36, a set of movable rollers 391 on the extension plate 37 can be pressed against the outside of the cup body. In the subsequent positioning process, the connection can be detected and fed back, reducing the possibility of misalignment at the joint affecting the subsequent welding quality.

[0030] like Figure 8 As shown, a positioning plate 33 is provided on the side of the connecting frame 32 near the limiting mechanism. A limiting suction cup is installed inside the positioning plate 33. A sealing ring frame 34 is movably sleeved on the outside of the positioning plate 33. The sealing ring frame 34 is used to press against the outside of the cup bottom. Several arc-shaped sealing strips are provided inside the sealing ring frame 34. A conveying pipe 211 is connected to the rotating disk 21. A sealing gasket 22 is installed on the side of the rotating disk 21 near the fixed shaft 23. Several conveying holes are opened on the sealing gasket 22. The rotating disk 21 is opened with conveying holes corresponding to the positions of the conveying holes. The air supply holes are connected to the conveying pipe 211. After the welding is completed, the sealing ring frame 34 can be attached to the outside of the welding position. The rotating disk 21 at the front end can deliver airflow to the inside of the welded cup body. At this time, the airflow sensing module is set inside the sealing ring frame 34. The welding quality is fed back by the airflow sensing module, reducing the situation of gaps in some areas. Rework welding can be carried out in time, reducing the defect rate of production.

[0031] like Figure 8 , Figure 9 and Figure 10As shown, the movable end block 36 is provided with a telescopic component, and an extension plate 37 is connected to the telescopic component. A set of conveying grooves is opened on the movable end of the extension plate 37, and a set of detection frames 39 is movably arranged inside the conveying grooves. The detection frames 39 are provided with adjustable snap-fit ​​frames at both ends, and a set of movable rollers 391 is provided on the snap-fit ​​frames. The movable rollers 391 are provided with pressure sensing modules. After the welding is completed, the set of movable rollers 391 can be pressed against the outside of the welded cup body. The movable rollers 391 can be set on both sides of the weld. With the help of the pressure sensing modules inside the movable rollers 391, the coaxiality of the welded cup body can be detected, and defective products can be screened out.

[0032] like Figure 9 and Figure 10 As shown, a grinding end block 38 is provided on the movable end of the extension plate 37. The grinding end block 38 has conductive arc surfaces at both ends. The grinding end block 38 has a snap-fit ​​groove, and a grinding plate is installed inside the snap-fit ​​groove. A round shaft is provided in the middle section of the inspection frame 39. The round shaft is used to snap onto the conductive arc surface and control the grinding end block 38 to be pulled outward. After the coaxiality of the cup body is tested, the inspection frames 39 at both ends can be controlled to move inward. By snapping onto the conductive arc surface, the grinding end block 38 can be moved outward. The grinding end block 38 can be attached to the outer wall of the cup body to perform grinding treatment on the components after welding, reducing the situation of weld slag residue.

[0033] like Figure 2 and Figure 3 As shown, a transmission guide rail 41 is movably mounted on the conveyor frame 4, and a mounting plate 42 is movably mounted on the transmission guide rail 41. The welding assembly is mounted on the mounting plate 42. By moving the transmission guide rail 41 and the mounting plate 42, the welding assembly can be positioned at the connection point of the cup body, enabling welding of the cylindrical cup body and the bottom of the cup.

[0034] In use, firstly, the cylindrical cup body is placed outside several clamping frames 26 by the limiting mechanism. The transmission disk 2 drives the rotating disk 21 to rotate. The movable end of the telescopic shaft 27 moves along the inclined guide plate 231 with the help of the support roller 271, pushing the clamping frame 26 to expand outward, so that the top buffer pad 261 elastically fits against the inner wall of the cup body to achieve pressing and limiting. At the same time, when the support roller 271 rotates, it can move the actuating plate 28 to drive the buffer pad 261 to vibrate slightly, reducing debris residue. Then, the docking mechanism is activated, the moving frame 31 moves forward along the fixed slide rail 3, and the movable end block 36 on the positioning frame 35 controls the extension plate 37 to make a set of movable rollers 391 abut against the outside of the cup body for auxiliary positioning. The sealing ring frame 34 presses against the bottom of the cup and cooperates with the limiting suction cup to complete the bottom of the cup. After positioning, the welding mechanism moves the welding assembly to the joint between the cup body and the cup bottom via the transmission guide rail 41 and the mounting plate 42 on the conveyor frame 4 to perform welding. After welding, the sealing ring frame 34 fits the weld, and the rotating disk 21 delivers airflow into the cup body through the conveying pipe 211. The airflow sensing module in the sealing ring frame 34 provides feedback on the welding airtightness. At the same time, the pressure sensing module in the movable roller 391 rolls along both sides of the weld to detect the coaxiality of the cup body. If the detection is qualified, the detection frame 39 is controlled to move inward, and the grinding end block 38 is pushed out to fit the outer wall of the cup body through the conduction arc surface to grind and remove the welding slag. If the detection is abnormal, it is screened out and reworked in time, thus completing the complete closed-loop process from positioning, welding, detection to grinding.
