Each adjustable slag-blocking mechanism includes a ring-shaped moving component and a slag-blocking component. The ring-shaped moving component drives the slag-blocking component to rotate around the central axis of the welding torch tip by a set angle. The slag-blocking component covers the area between the welding torch tip and the corresponding channel or hole.

Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically, to a welding apparatus for a stroller frame component. Background Technology

[0002] Children's vehicles are transportation and entertainment tools designed specifically for children, covering categories such as children's bicycles, strollers, tricycles, electric toy cars, and baby walkers.

[0003] The frame of a children's stroller is assembled by welding rods of corresponding shapes and parameters. When welding the rods and / or corresponding connecting auxiliary structural components, the rods and / or corresponding connecting auxiliary structural components are usually clamped and positioned by setting a fixture, and then the welding torch is controlled to weld along a set welding path. However, as the functionality of children's strollers increases, the rods have added many connecting holes or connectors with connecting holes to accommodate the installation of corresponding expansion functional modules. During the welding process, the commonly used anti-spatter welding torches mostly use gas for directional blocking or use special anti-spatter plugging devices to block the corresponding channels. However, if the channels are close together, slag will still appear. The generated welding slag moves with the airflow into the channels of the corresponding rods or connectors, increasing the complexity of subsequent cleaning and installation accuracy. Blocking the channels will increase welding costs and may also lead to a more complex welding path or reduced welding efficiency. Summary of the Invention

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 5 As shown, a welding device for a stroller frame component includes: The position adjustment mechanism 1 includes a dual-station moving component and two sets of angle adjustment components connected to the dual-station moving component. The dual-station moving component is used to drive the two sets of angle adjustment components to move synchronously or asynchronously. Two sets of welding torches 2 are detachably mounted on two sets of angle adjustment components. The angle adjustment components are used to adjust the angle between the welding torch 2 and the horizontal plane. Rotary platform 3 is located on the side of the dual-station moving assembly; Two sets of limiting fixtures 4 are symmetrically installed on the rotating platform 3; Two sets of adjustable slag-blocking mechanisms 5 are installed on two sets of welding torches 2 respectively. The adjustable slag-blocking mechanism 5 includes an annular moving component installed on the welding torch 2 and a slag-blocking component connected to the annular moving component. The annular moving component is used to drive the slag-blocking component to rotate around the central axis of the end of the welding torch 2 at a set angle. The slag-blocking component is used to cover the area between the end of the welding torch 2 and the corresponding channel or hole.

[0020] It should be noted that when welding the rod body components of the stroller, the corresponding rod body and parts to be welded are assembled with the corresponding limiting fixture 4 by manual labor or a robotic arm, and then fixed by the limiting fixture 4. After fixing, the assembled limiting fixture 4 is rotated to the welding position of the corresponding welding gun 2 by the rotating platform 3. At this time, the two sets of angle adjustment components and the welding gun 2 installed in the angle adjustment component row can be driven by the position adjustment mechanism 1 to move synchronously or asynchronously to the starting point of the welding path. Then, the position adjustment mechanism 1 and the angle adjustment components are driven synchronously or asynchronously. The corresponding welding torch 2 moves along the set welding path. During this process, the ring moving component drives the corresponding slag blocking component to change its position according to the set program. This ensures that the slag blocking component can always block the welding torch 2 and the corresponding channel or hole when it moves along the set welding path. This prevents some welding slag that is inevitably generated during welding from splashing into the corresponding channel or hole, thus ensuring that the channel or hole on the welded rod assembly will not have welding slag, which would cause difficulties in later assembly or produce abnormal noise.

[0021] In an optional embodiment of the invention, such as Figures 1 to 3 As shown, the dual-station moving assembly includes a frame 101, a linear moving assembly 1 mounted on the frame 101, two sets of linear moving assemblies 2 mounted in parallel on the linear moving assembly 1, and a linear moving assembly 3 connected to the linear moving assembly 2. An angle adjustment assembly is mounted on the corresponding linear moving assembly 3. The linear moving assembly 1 is used to drive the two sets of linear moving assemblies 2 to move synchronously toward or away from the limiting fixture 4. The linear moving assembly 2 is used to drive the linear moving assembly 3 to move along the length direction of the limiting fixture 4. The linear moving assembly 3 is used to drive the angle adjustment assembly to move toward or away from the limiting fixture 4.

[0022] The linear motion assembly includes two sets of rails 102 symmetrically mounted on frame 101, a bearing bracket 103 fixedly mounted on frame 101, a screw 104 connected to bearing bracket 103, a motor 105 fixedly mounted on frame 101, a sliding platform 106 slidably connected to rail 102, and two sets of rails 107 symmetrically mounted on sliding platform 106. The output shaft of motor 105 is connected to screw 104, and screw 104 is threadedly connected to sliding platform 106.

[0023] The second linear motion component includes a bearing bracket 108 fixedly mounted on a sliding platform 106, a screw 109 movably connected to the bearing bracket 108, a motor 110 fixedly mounted on the sliding platform 106, and a sliding platform 111 slidably connected to a track 107. The output shaft of the motor 110 is connected to the screw 109, and the sliding platform 111 is threadedly connected to the screw 109.

[0024] The linear motion assembly includes a track 112 fixedly mounted on the sliding platform 111, a sliding platform 113 slidably connected to the track 112, a motor 114 fixedly mounted on the sliding platform 111, and a screw 115 connected to the output shaft end of the motor 114. The sliding platform 113 and the screw 115 are threadedly connected.

[0025] It should be noted that, as mentioned above, when the two sets of angle adjustment components and the two sets of welding torches 2 are driven to move along the set welding path by the dual-station moving component, the screw 104 is rotated by the motor 105. This rotates the sliding platform 106, which is threadedly connected to the screw 104 and slidably connected to the track 102, along the length of the screw 104. The length of the screw 104 points towards the limiting fixture 4. Therefore, when the screw 104 rotates, the sliding platform 106 is driven to move closer to or further away from the corresponding limiting fixture 4, and simultaneously drives the two sets of linear moving components 2 mounted on the sliding platform 106 to move synchronously. When the welding paths corresponding to the two sets of welding torches 2 are symmetrical and synchronous, the two sets of angle adjustment components can be synchronously driven by the two sets of linear moving components 2 and 3 to move symmetrically and synchronously. For the same movement, if there is asynchronous welding or different welding paths, the two sets of linear movement components two and three can drive the corresponding angle adjustment components to move asynchronously. When the welding torch 2 moves along the length direction of the limiting fixture 4, the screw 109 can be rotated by the motor 110. When the screw 109 rotates, the corresponding sliding platform 111 can be moved along the length direction of the limiting fixture 4. The movement of the two sets of sliding platforms 111 does not affect each other. At the same time, the screw 115 can be rotated by the motor 114, so that the sliding platform 113 moves along the track 112, so that the two sets of welding torches 2 can move asynchronously toward or away from the limiting fixture 4, which can effectively improve welding efficiency. Moreover, the movement coordinate system and the base are unified, which can effectively reduce the error generated during asynchronous welding.

[0026] In an optional embodiment of the invention, such as Figures 1 to 3 As shown, the angle adjustment assembly includes a fixed bracket 116 fixedly installed on the upper end of the sliding platform 113, a movable bracket 117 movably connected to the fixed bracket 116, and a motor 118 fixedly installed on the movable bracket 117. The output shaft end of the motor 118 passes through the movable bracket 117 and is fixedly connected to the fixed bracket 116.

[0027] It should be noted that, as mentioned above, when the welding torch 2 is driven to move along the set welding path, the motor 118 can also work at the same time. When its output shaft rotates, it can drive its own body to rotate around the fixed connection with the fixed bracket 116, and drive the movable bracket 117, which is movably connected to the fixed bracket 116, to rotate synchronously. This drives the corresponding welding torch 2 to adjust the angle between itself and the horizontal plane to adapt to the changes in the current welding path and the flipping of the workpiece to be welded.

[0028] In an optional embodiment of the invention, such as Figure 1 As shown, the rotating platform 3 includes a frame 2 301, a rotating shaft 302 movably connected to the frame 2 301, a motor 5 303 fixedly installed on the frame 2 301, a gear 1 connected to the output shaft end of the motor 5 303, a gear 2 fixedly installed on the rotating shaft 302, and a mounting platform 304 connected to the upper end of the rotating shaft 302. The gear 1 and gear 2 mesh with each other, and two sets of limiting fixtures 4 are symmetrically installed on the mounting platform 304.

[0029] It should be noted that, as mentioned above, the two sets of limiting fixtures 4 are symmetrically distributed on the installation platform 304. The limiting fixtures 4 can be adapted and replaced according to the structure of the rod assembly being welded. The limiting fixture 4 that currently limits and fixes the rod assembly is located at the welding position of the two sets of welding guns 2, while the other set of limiting fixtures 4 is located at the position where the new rod assembly is limited and fixed. This alternation can effectively improve the welding efficiency. When the positions of the two sets of limiting fixtures 4 are alternating, the motor 5 303 installed on the frame 2 301 drives the gear 2 on it to rotate. When the gear 2 rotates, it drives the gear 1 that meshes with it to rotate. When the gear 1 rotates, it drives the rotating shaft 302 to rotate synchronously, and synchronously drives the installation platform 304 to rotate.

[0030] In an optional embodiment of the invention, such as Figure 3 and Figure 4 As shown, the annular moving assembly includes a hollow mounting plate 501 fixedly mounted on the welding torch 2, a rotating ring 502 movably connected to the hollow mounting plate 501, a motor 503 fixedly mounted on the hollow mounting plate 501, a gear 3 fixedly connected to the rotating ring 502, and a gear 4 fixedly connected to the output shaft end of the motor 503. The gear 3 and the gear 4 mesh with each other.

[0031] It should be noted that, as mentioned above, when the welding torch 2 moves along the set welding path, when it moves to a nearby channel or hole on the path, the slag-blocking component is driven to move to the corresponding blocking position in advance by the annular moving component. Specifically, the motor 6 503 drives the gear 4 connected to its output shaft to rotate. When the gear 4 rotates, it drives the gear 3 meshing with it to rotate. When the gear 3 rotates, it drives the rotating ring 502 fixedly connected to it to rotate synchronously. The rotating ring 502 does not contact the welding torch 2. When it rotates, it drives the slag-blocking component to rotate synchronously, so that the slag-blocking component can rotate around the central axis of the end of the welding torch 2 at a set angle. This allows it to be controlled by the program and continuously change its angle during the movement of the welding torch 2, so that it can always intercept welding slag splashing into the corresponding channel or hole, thereby effectively ensuring the high quality of the welded product.

[0032] In an optional embodiment of the invention, such as Figures 3 to 5 As shown, the slag-blocking assembly includes a slag-blocking plate 504 and a bidirectional sliding interceptor slidably connected to the slag-blocking plate 504. The slag-blocking plate 504 is detachably connected to the rotating ring 502. The slag-blocking plate 504 includes a vertical part and an inclined part integrally formed with the vertical part. The bottom of the inclined part is provided with a sliding groove that cooperates with the bidirectional sliding interceptor. A limiting groove is provided on the inner wall of the sliding groove.

[0033] The bidirectional sliding interceptor includes a sliding plate 505 slidably connected to the inner wall of the first sluice, a limiting block fixedly connected to the sliding plate 505, a spring 1 connected between the outer wall of the limiting block and the inner wall of the limiting groove, a slider fixedly connected to the outer wall of the sliding plate 505, a second sluice plate 506 arranged parallel to the inclined portion of the first sluice plate 504, a second sluice on the second sluice plate 506, and a second spring 2 connected between the slider and the second sluice. The second sluice plate 506 is in contact with the inclined portion of the first sluice plate 504.

[0034] It should be noted that, as mentioned above, before welding different rod components, the corresponding slag-blocking components can be adjusted and replaced according to the welding path, the position and parameters of the channels or holes, and whether there are obstructive structures. When welding begins, the slag-blocking plate 504 can rotate synchronously with the rotating ring 502 and move synchronously with the welding torch 2. During this process, the sliding plate 505 and the slag-blocking plate 506 can move synchronously with the slag-blocking plate 504 under the action of the corresponding springs 1 and 2. When the slag-blocking plate 506 contacts the rod component during its movement, the sliding plate 505 will slide in the groove 1 set on the slag-blocking plate 504 due to the influence of the resistance component, and drive the slag-blocking plate 506 to move synchronously. The movement, and the sliding of the second slag-blocking plate 506 toward the vertical part of the first slag-blocking plate 504, can be performed independently or simultaneously. This allows the first slag-blocking plate 504 and the second slag-blocking plate 506 to adaptively adapt to the structure of the area contacted by the current rod assembly when intercepting the corresponding area. At the same time, the distribution state of the first slag-blocking plate 504 and the second slag-blocking plate 506 can be assisted by rotating the ring 502 and working the angle adjustment assembly. This can further improve the diversity of the interception area without affecting the continuity of the welding path. The lower corner area of ​​the second slag-blocking plate 506 is arc-shaped, which can effectively improve the stability of its positional deformation, such as the generation of the component forces of resistance in different directions.

[0035] The above description of this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
