Description

Technical Field

[0001] The invention relates to the technical field of cookware welding, in particular to a welding device for processing cookware. Background Art

[0002] Dividers (e.g., the dividers in a shuangyang hot pot or the dividers in a nine-square griddle) are installed inside a pot (e.g., a hot pot) to physically separate the cooking areas, thereby satisfying the diverse dietary needs of users. These dividers are typically welded to the inner wall of the metal pot.

[0003] However, in the processing of specific pots such as the "Shuangyang" pot, in order to achieve a better appearance, the central partition is often designed into an arc-shaped structure. This structure causes the joint line between the bottom edge of the partition and the bottom of the pot to take the form of a spatial curve. During welding operations, in order to weld along this curved trajectory, the operator needs to be highly skilled in manually controlling the welding gun to track the welding. The inherent limitations of manual operation make it difficult to ensure the consistency and repeatability of the weld trajectory, which in turn affects the uniformity and appearance quality of the weld. Therefore, there is an urgent need to improve the welding equipment for this type of arc weld to improve welding efficiency and the quality of the finished product. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 13 A welding device for processing cookware includes a supporting horizontal plate 1, with frame-shaped legs 2 provided at both ends of the supporting horizontal plate 1. The frame-shaped legs 2 are fixed to the left and right ends of the supporting horizontal plate 1 in a circular shape, thereby supporting the entire welding device through the frame-shaped legs 2. The device also includes a welding mechanism 3 and a partition clamping mechanism 4.

[0030] The partition clamping mechanism 4 includes a top bracket 7 arranged above the supporting horizontal plate 1. The top bracket 7 is a U-shaped structure with an opening downward. The left and right ends of the top bracket 7 are fixedly connected to the left and right ends of the upper surface of the supporting horizontal plate 1 respectively. A vertically arranged rotating sleeve 8 is rotatably connected in the middle of the top bracket 7. A vertically arranged rotating column 9 is slidably connected in the middle of the rotating sleeve 8. The lower end of the rotating column 9 is fixedly connected to the partition clamping block 10. An arc groove is provided below the partition clamping block 10. The interior of the arc groove is made of rubber material, so that the arc partition 6 can be inserted into the arc groove from bottom to top. The arc partition 6 is detachably connected through the partition clamping block 10. A space moving drive component 11 is provided on the top bracket 7. The space moving drive component 11 can drive the rotating sleeve 8 to rotate. The space moving drive component 11 can also drive the rotating column 9 to move up and down, so that the partition clamping block 10 drives the arc partition 6 to move in space;

[0031] The welding mechanism 3 includes a bottom bracket 19 arranged below the supporting horizontal plate 1. The bottom bracket 19 is a U-shaped structure with an opening upward. The left and right ends of the bottom bracket 19 are respectively fixedly connected to the left and right ends of the lower surface of the supporting horizontal plate 1. A transverse seat 21 that slides left and right along the bottom bracket 19 is provided at the lower part of the bottom bracket 19. A U-shaped sliding seat 22 facing forward and backward is provided above the transverse sliding seat 21. The U-shaped sliding seat 22 moves left and right synchronously with the transverse sliding seat 21. A telescopic rod 23 facing forward and backward is slidably connected to the upper end of the U-shaped sliding seat 22. The front end of the telescopic rod 23 is fixedly connected to a fixed block 24. A vertical column 49 is provided on the upper surface of the fixed block 24. The upper end of the column 49 is rotatably connected to a laser welding head 25. A pitch adjustment assembly 26 is provided on the front side of the shift seat 21, and the pitch adjustment assembly 26 can drive the laser welding head 25 to pitch and rotate, and a tracking guide block 29 is provided in the middle of the lower surface of the supporting horizontal plate 1, and a guide groove 30 is provided in the middle of the tracking guide block 29. The size of the guide groove 30 is matched with the size of the arc partition 6. A transverse block 27 is provided in the middle of the telescopic rod 23, and a shift rod 28 that moves along the guide groove 30 is provided on the upper surface of the transverse block 27. Therefore, when the transverse block 27 moves in space, the shift rod 28 moves along the guide groove 30, so that the moving trajectory of the laser welding head 25 is matched with the size of the arc partition 6, so that the laser welding head 25 can weld the arc partition 6 and the pot body 5.

[0032] In one embodiment of the present invention, see Figure 1 、 Figure 7 、 Figure 8 and Figure 9A pot storage assembly 20 is provided in the middle of the upper surface of the supporting horizontal plate 1. The pot 5 can be placed into the pot storage assembly 20 from top to bottom, thereby achieving the fixing of the pot 5. The pot storage assembly 20 includes U-shaped frames 35 distributed in a circumferential array. The three U-shaped frames 35 are fixedly connected to each other and are opened upward. A fixing ring 36 is fixedly connected to the upper end of the U-shaped frame 35, so that a container opened upward is formed by the fixing ring 36 and the U-shaped frame 35. A horizontally arranged top rod 32 is slidably connected to the side of the U-shaped frame 35. A clamping wheel 34 is provided at one end of the top rod 32 close to the center of the supporting horizontal plate 1, and a clamping spring 33 is provided between the clamping wheel 34 and the U-shaped frame 35. The holding spring 33 is sleeved on the outside of the top rod 32, and a counterweight block 31 is provided at the end of the top rod 32 away from the center of the supporting cross plate 1. The counterweight block 31 will rotate to a vertical state under the action of gravity. At this time, the axis of the clamping wheel 34 is set horizontally, so that when the pot body 5 is placed from top to bottom, the clamping wheel 34 will rotate adaptively, and because the top rod 32 and the U-shaped frame 35 can rotate with each other, when the pot body 5 rotates, the axis of the clamping wheel 34 will rotate adaptively to a vertical state.

[0033] In one embodiment of the present invention, see Figure 7-11The shift rod 28 can move left and right along the guide groove 30, and the transverse shift seat 21 and the U-shaped sliding seat 22 are relatively displaced. Therefore, when the shift rod 28 moves to the end of the guide groove 30, the shift rod 28 stops moving. At this time, the transverse shift seat 21 and the U-shaped sliding seat 22 are relatively displaced, thereby driving the laser welding head 25 to perform pitch rotation processing through the subsequent pitch adjustment component 26. The pitch adjustment assembly 26 includes a vertically arranged vertical rod 42, which is slidably connected to the front side of the fixed block 24, and the upper end of the vertical rod 42 is rotatably connected to the lower end of the top plate 41, and the upper end of the top plate 41 is rotatably connected to the rear side of the laser welding head 25. A top wheel 44 is set at the lower end of the vertical rod 42, and a bracket 45 arranged in a front-to-back direction is set on the front side of the transverse movement seat 21. A trapezoidal top block 43 is set on the front side of the upper surface of the bracket 45, and the middle part of the trapezoidal top block 43 is in a convex state. In the normal state, the upper end of the trapezoidal top block 43 contacts the top wheel 44. At this time, the vertical rod 42 is at a high position and the laser welding head 25 is facing downward. However, after the transverse movement seat 21 and the U-shaped sliding seat 22 are relatively displaced, the top wheel 44 moves to the inclined surfaces on both sides of the trapezoidal top block 43. At this time, the top wheel 44 and the vertical rod 42 will move downward under the action of gravity, and the laser welding head 25 will be lifted upward, thereby causing the welding position to move upward. The front and rear sides of the transverse moving seat 21 are slidably connected with a sliding frame 46 of a U-shaped structure, and the upper end of the sliding frame 46 is fixedly connected to the front and rear sides of the U-shaped sliding seat 22. A guide slide bar 47 that slides left and right with the transverse moving seat 21 is provided in the middle of the sliding frame 46. Return springs 48 are provided on the left and right sides of the guide slide bar 47. The two return springs 48 push the U-shaped sliding seat 22 toward the center of the transverse moving seat 21, so that the U-shaped sliding seat 22 is centered. When the shift rod 28 moves to the end of the guide groove 30, the transverse moving seat 21 continues to move, and the degree of compression of the return spring 48 on one side increases, and the degree of compression of the return spring 48 on the other side decreases. At this time, the transverse moving seat 21 and the U-shaped sliding seat 22 are staggered with each other, so that after the shift rod 28 moves to the end of the guide groove 30, the laser welding head 25 will be lifted, so that the vertical edges at both ends of the arc-shaped partition 6 are welded.

[0034] In one embodiment of the present invention, see Figure 10 A horizontally disposed transverse screw 40 is rotatably connected to the lower portion of the bottom bracket 19. The left and right sides of the transverse screw 40 are rotatably connected to the bottom bracket 19. The middle portion of the transverse screw 40 is threadedly connected to the middle portion of the transverse seat 21. A drive motor 37 is disposed on the right side of the bottom bracket 19. The output shaft of the drive motor 37 is fixedly connected to a first bevel gear 38. The first bevel gear 38 is meshedly connected to a second bevel gear 39 fixedly connected to the end of the transverse screw 40. The drive motor 37 rotates the transverse screw 40 through a gear transmission, which drives the transverse seat 21 to move left and right along the bottom bracket 19.

[0035] In one embodiment of the present invention, see Figure 4-Figure 6 The spatial movement drive assembly 11 includes a lifting cylinder 12 arranged on the left side of the top bracket 7, the piston rod of the lifting cylinder 12 extends to the right side, and the piston rod of the lifting cylinder 12 is fixedly connected to the upper surface of the lifting slider 13 arranged in a front-to-back direction, and the left side of the top bracket 7 is slidably connected to the middle part of the lifting slider 13, and the lower end of the lifting support rod 14 is rotatably connected to the front and back sides of the upper surface of the lifting slider 13, and the upper end of the lifting support rod 14 is rotatably connected to the front and back ends of the lifting push plate 15 arranged in a front-to-back direction, and the middle part of the lifting push plate 15 is rotatably connected to the upper end of the rotating column 9. Therefore, when the piston rod of the lifting cylinder 12 pushes the lifting slider 13 to move left and right, the lifting slider 13 pushes the lifting push plate 15 up and down through the lifting support rod 14, thereby causing the rotating column 9 to move up and down. A rotating seat 18 is provided on the upper right surface of the top bracket 7, and the rotating seat 18 is rotatably connected to the reversing cylinder 17. The piston rod of the reversing cylinder 17 extends to the left, and the piston rod of the reversing cylinder 17 is rotatably connected to one end of the deflection plate 16. The other end of the deflection plate 16 is fixedly connected to the rotating sleeve 8. Therefore, when the piston rod of the reversing cylinder 17 is extended or retracted, the deflection plate 16 drives the rotating sleeve 8 to rotate forward or reverse, and after the piston rod of the reversing cylinder 17 is fully extended, the rotating sleeve 8 rotates exactly one hundred and eighty degrees, thereby realizing a one hundred and eighty degree reversal of the arc partition 6.

[0036] During the implementation of this embodiment, the lifting cylinder 12 is started and the partition clamping block 10 is raised. At this time, the pot body 5 is placed into the pot body storage assembly 20 from top to bottom, and the pot body 5 is centered due to the action of the clamping wheel 34 and the clamping spring 33. The arc-shaped partition 6 is inserted into the groove of the partition clamping block 10 from bottom to top. At this time, the lifting cylinder 12 is started in reverse, the rotating column 9 moves downward, and the partition clamping block 10 drives the arc-shaped partition 6 to move downward and fall into the interior of the pot body 5. At this time, the bottom of the arc-shaped partition 6 is in contact with the bottom of the pot body 5, and the two ends of the arc-shaped partition 6 are in contact with the inner wall of the pot body 5, thereby realizing the assembly of the cookware.

[0037] The laser welding head 25 is turned on and the laser welding head 25 starts welding. After moving to the left end of the guide groove 30, the shift rod 28 and the U-shaped sliding seat 22 stop moving. At this time, the transverse seat 21 continues to move to the left, and the inclined surface of the trapezoidal top block 43 contacts the top wheel 44. At this time, the laser welding head 25 is lifted, so that the laser welding head 25 welds the vertical edge of the left side of the arc-shaped partition 6. When the laser welding head 25 is fully lifted, the laser welding head 25 is stopped, and the reversing cylinder 17 is started. The piston rod of the reversing cylinder 17 extends. At this time, since one side of the arc-shaped partition 6 has been welded to the pot body 5, the pot body 5 rotates one hundred and eighty degrees with the arc-shaped partition 6. After the rotation is completed, the laser welding head 25 is turned on, and the drive motor 37 is started in reverse. At this time, the laser welding head 25 first rotates downward to complete the welding of the vertical edge of one end of the arc-shaped partition 6, and then the laser welding head 25 continues to move to the right and then lifts up, so that both sides of the arc edge and the vertical edge of the arc-shaped partition 6 are effectively welded.

[0038] The present invention provides a welding device for processing cookware. Through the coordinated action of the shifting rod 28 and the guide groove 30, the laser welding head 25 is driven to move precisely along a predetermined trajectory, thereby realizing the automated welding processing of the spatial curved weld between the arc-shaped partition 6 and the inner wall of the pot body 5. The above-mentioned automation mechanism effectively eliminates the uncertainty of manual operation, ensures the high consistency of the welding trajectory and the stability of the process parameters. Therefore, in the same batch and different batches of cookware, the geometry, penetration depth and appearance of the weld between the arc-shaped partition 6 and the pot body 5 have excellent repeatability.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
