Description

Technical Field

[0001] This invention relates to the field of automatic welding technology, and in particular to a multi-angle welding device and welding method. Background Technology

[0002] Electronic products used in the 3C (computer, communication and consumer electronics) industry often involve rotating structures, which typically include a rotating shaft and rotation position limits.

[0003] In a product having a housing and a disc, the disc is rotatably connected to the housing via a rotating shaft. The maximum opening angle of the disc relative to the housing is 75°, and the closing angle is -1°. In this product, the rotating shaft is fixedly connected to the disc, and a limiting component is welded onto the rotating shaft. When the disc is closed relative to the housing, the limiting component abuts against the limiting part of the housing.

[0004] In existing technologies, the process of welding the limiting component to the rotating shaft typically involves manually fixing the limiting component to the rotating shaft and then welding it using a welding torch. Manual welding is labor-intensive and inefficient. Furthermore, because the rotating shaft is cylindrical, axial movement or rotation around the shaft is prone to occur during welding, causing changes in their relative positions. This results in the disc's relative angle to the outer shell being compromised, leading to defective products and a lower yield rate.

[0005] Therefore, it is urgent to study a welding device and welding method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a multi-angle welding device and welding method to solve the problems of low efficiency and low yield of manual welding in the prior art.

[0021] The ballast assembly includes a ballast body and a ballast component. The ballast body has a positioning protrusion on one side. One end of the ballast component is rotatably disposed on the ballast body and can move between a first ballast position and a first clearance position. The ballast body can be placed on the bearing seat. The positioning protrusion can be inserted into the intermediate groove. The first workpiece can be clamped between the second workpiece and the ballast component located at the first ballast position.

[0022] In some embodiments, the ballast body has a positioning hole and a insertion slot, the extension direction of the positioning hole being perpendicular to the extension direction of the insertion slot; the bearing seat is provided with a positioning pin, the positioning pin being able to pass through the positioning hole; the multi-angle welding device includes an insertion assembly, the insertion end of the insertion assembly being able to be inserted into the insertion slot.

[0059] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0060] Example 1

[0061] like Figures 1 to 12As shown, this embodiment provides a multi-angle welding device for welding a first workpiece to a second workpiece. The multi-angle welding device includes a frame 100, a worktable 200, a carrier assembly 300, and a welding component 400. The worktable 200 is rotatably mounted on the frame 100 about a first axis and can rotate between a first initial position, a first position, and a second position. The first axis is parallel to the Y direction. The carrier assembly 300 includes a support 310 and a load assembly 320. The support 310 carries the product, which includes the first workpiece and the second workpiece. Ballast assembly 320 is detachably connected to bearing base 310 for fixing the first workpiece relative to the second workpiece; weldment 400 is disposed on frame 100; when worktable 200 rotates to the first position, the first welding area H1 between the first workpiece and the second workpiece faces weldment 400; when worktable 200 rotates to the second position, the second welding area H2 between the first workpiece and the second workpiece faces weldment 400; when worktable 200 is in the first initial position, the third welding area H3 between the first workpiece and the second workpiece faces weldment 400.

[0062] With the aforementioned structural configuration, when the worktable 200 rotates to each position, the corresponding welding area between the first and second workpieces can be aligned with the welding part 400, enabling welding at that position and completing automated welding at multiple angles, thus improving welding efficiency. Furthermore, by setting up the ballast assembly 320 to fix the first and second workpieces, misalignment between them during the welding process is prevented, thereby improving the relative positional accuracy between the second and first workpieces and ensuring a high yield rate.

[0063] The multi-angle welding device includes a rotary drive component 210, which is mounted on the frame 100 and has its output end connected to the worktable 200 for driving the worktable 200 to rotate. The rotary drive component 210 can be a servo motor, with a connecting shaft rotatably mounted on the frame 100 and connecting the worktable 200 and the rotary drive component 210. The first axis is the axis of the connecting shaft.

[0064] The product is a rotatable wireless charger, comprising a base component, a mating component, a first workpiece, and a second workpiece. The second workpiece is rotatably mounted on the base component, the mating component is connected to the second workpiece, and the first workpiece is mounted on the second workpiece. The base component has a first limiting surface 1100, and the first workpiece has a second limiting surface 3100. When the second workpiece is in a second initial position, the first limiting surface 1100 and the second limiting surface 3100 abut against each other. In this embodiment, the base component can be a housing 1000 serving as the mounting body, the mating component can be a charging disc 2000, the second workpiece is a rotating shaft 4000, and the first workpiece is a limiting component 3000. When the disc 2000 is in an open state relative to the housing 1000, the included angle between them is 45°. When the disc 2000 is in a closed state relative to the housing 1000, the included angle between them is -1°, meaning that part of the plane containing the disc 2000 is above the plane containing the housing 1000. At this time, the first limiting surface 1100 and the second limiting surface 3100 abut against each other.

[0065] The rotating shaft 4000 is rod-shaped, and the limiting member 3000 includes a mating surface 3300 and an intermediate groove 3200. The projection of the mating surface 3300 along the axial direction of the rotating shaft 4000 is arc-shaped. The intermediate groove 3200 passes through the limiting member 3000 along a direction perpendicular to the axial direction of the rotating shaft 4000. The opening direction of the intermediate groove 3200 is perpendicular to the axial direction of the rotating shaft 4000. The mating surface 3300 is mated to the outer surface of the rotating shaft 4000. The first welding area H1 is the intersection of one end of the limiting member 3000 along the axial direction of the rotating shaft 4000 and the rotating shaft 4000. The second welding area H2 is the intersection of the other end of the limiting member 3000 along the axial direction of the rotating shaft 4000 and the rotating shaft 4000. The third welding area H3 is the intersection of the outline edge of the intermediate groove 3200 of the limiting member 3000 and the rotating shaft 4000. The fourth welding area H4 is located at the intersection of the second limiting surface 3100 and the rotation axis 4000. Specifically, the first welding area H1 is a single arc. The second welding area H2 is a single arc. The third welding area H3 is a U-shaped arc. The fourth welding area H4 is a straight line.

[0066] The ballast assembly 320 includes a ballast body 321 and a ballast member 322. One side of the ballast body 321 has a positioning protrusion 3231. One end of the ballast member 322 is rotatably mounted on the ballast body 321 and can move between a first ballast position and a first clearance position. The ballast body 321 can be placed on the bearing seat 310. The positioning protrusion 3231 can be inserted into the intermediate groove 3200. The limiting member 3000 can be clamped between the rotating shaft 4000 and the ballast member 322 located at the first ballast position. This arrangement ensures that the side walls of the positioning protrusion 3231 abut against the side walls of the intermediate groove 3200, thereby guaranteeing the positional accuracy of the limiting member 3000 relative to the rotating shaft 4000 along the axial direction of the rotating shaft 4000. When welding the first welding area H1, the rotating shaft 4000 is in the second initial position, that is, the disk 2000 is in a closed state relative to the outer shell 1000, that is, the included angle between the two is -1°. In this state, the first limiting surface 1100 and the second limiting surface 3100 are in contact, and the end of the positioning protrusion 3231 away from the ballast body 321 abuts against the bottom of the intermediate groove 3200.

[0067] Specifically, the positioning rod 323 is slidably disposed on the ballast body 321 and can move between the first positioning position and the second positioning position. A spring is disposed between the positioning rod 323 and the ballast body 321 to stop the positioning rod 323 at the first positioning position. A positioning protrusion 3231 is disposed at one end of the positioning rod 323. When the positioning rod 323 is in the first positioning position, the positioning protrusion 3231 abuts against the bottom of the intermediate groove 3200, thereby making the second limiting surface 3100 of the limiting member 3000 fit with the first limiting surface 1100.

[0068] In some embodiments, the worktable 200 needs to rotate 90 degrees from the first position to the second position. In other words, the worktable 200 rotates 45° clockwise from the first initial position to the first position, and the worktable 200 rotates 45° counterclockwise from the first initial position to the second position.

[0069] When the rotating shaft 4000 is in the second initial position, the fourth welding area H4 is blocked, and welding cannot be completed. Therefore, in some embodiments, the multi-angle welding device includes a pressing component 500, which is disposed on the frame 100 and can drive the rotating shaft 4000 to rotate around a second axis from the second initial position to a third position. The second axis is parallel to the X direction, and the X direction is perpendicular to the Y direction. When the rotating shaft 4000 is in the third position, the fourth welding area H4 between the limiting member 3000 and the rotating shaft 4000 faces the weldment 400. At this time, the first welding area H1, the second welding area H2, and the third welding area H3 are all welded. Therefore, the rotating shaft 4000 can drive the limiting member 3000 to rotate simultaneously during the rotation process, causing the first limiting surface 1100 and the second limiting surface 3100 to separate. Specifically, the pressing component 500 drives the disk 2000 to rotate relative to the outer shell 1000. This configuration allows the pressing end of the pressing component 500 to be positioned above the product and to smoothly press against the disc 2000. The second axis is the axis of the rotating shaft 4000.

[0070] The pressing assembly 500 includes a pressing drive assembly, an elastic element 540, and a pressing element 550. The pressing drive assembly is mounted on the frame 100. The pressing element 550 is slidably mounted on the output end of the pressing drive assembly along the Z direction. The elastic element 540 is located between the pressing element 550 and the output end of the pressing drive assembly, and is used to apply a downward force to the pressing element 550. Specifically, the pressing element 550 is movable between a first pressing position and a second pressing position. The first pressing position is located above the second pressing position, and the elastic element 540 is used to stop the pressing element 550 in the second pressing position. The pressing element 550 is used to press against the disk 2000, thereby causing the rotating shaft 4000 to rotate to a third position.

[0071] The pressing drive assembly includes a first pressing drive member 510, a second pressing drive member 520, and a third pressing drive member 530. The first pressing drive member 510 is mounted on the frame 100. Its output end is connected to the second pressing drive member 520 and is used to drive the second pressing drive member 520 to move along the Y direction. The output end of the second pressing drive member 520 is connected to the third pressing drive member 530 and is used to drive the third pressing drive member 530 to move along the X direction. The output end of the third pressing drive member 530 is connected to the pressing plate 560 and is used to drive the pressing member 550 to move along the Z direction. The pressing member 550 is slidably mounted on the pressing plate 560 along the Z direction, and a spring is disposed between the pressing plate 560 and the pressing member 550.

[0072] The multi-angle welding device includes a pusher assembly 600, which is mounted on the worktable 200. A pressing assembly 500 drives a rotating shaft 4000 to move from a third position to a second initial position around a second axis. This arrangement allows the disc 2000 to reset, facilitating subsequent material handling. Furthermore, by mounting the pusher assembly 600 on the worktable 200, it can rotate simultaneously with the worktable 200, avoiding interference and improving safety while reducing design complexity.

[0073] Specifically, the worktable 200 is provided with an arc-shaped slide groove 220, and the push assembly 600 includes a push base 610 and a push drive 620. The push base 610 is provided with a sliding pin 611 and a sliding channel. The sliding pin 611 is slidably disposed in the arc-shaped slide groove 220. The push drive 620 is disposed on the push base 610, and the output end of the push drive 620 passes through the sliding channel and drives the rotating shaft 4000. The push drive 620 includes a telescopic cylinder. The piston rod of the telescopic cylinder passes through the sliding channel and can abut against the disc 2000, causing the disc 2000 to rotate upward to a closed position relative to the outer shell 1000, thereby driving the rotating shaft 4000 to move from a third position to a second initial position around the second axis. This design ensures that during the extension and retraction of the piston rod of the telescopic cylinder, the piston rod abuts against the disc 2000, and the cylinder body of the telescopic cylinder undergoes an angular change. This prevents relative sliding between the piston rod and the disc 2000, thus avoiding scratches on the disc 2000.

[0074] There are two sliding pins 611, which are spaced apart and both slide in the arc-shaped groove 220.

[0075] The multi-angle welding device includes a clamping assembly 570, which is located at the output end of the pressure drive assembly and can clamp the ballast assembly 320. With this structure, after the clamping assembly 570 clamps the ballast assembly 320, the ballast assembly 320 can be moved to the side of the limiting member 3000, thereby exposing the third welding area H3, which can then be welded by the workpiece 400. The clamping assembly 570 can be a gripper cylinder.

[0076] The multi-angle welding device includes a fixing assembly 700, which comprises a fixing member 710 and a fixing drive member 720. The fixing drive member 720 is disposed on the worktable 200, and the fixing member 710 is disposed at the output end of the fixing drive member 720. The fixing drive member 720 is used to drive the fixing member 710 to move between a second ballast position and a second clearance position. When the fixing member 710 is in the second ballast position, the bearing seat 310 is clamped between the worktable 200 and the fixing member 710. This structure ensures that the bearing seat 310 rotates synchronously with the worktable 200 during rotation, preventing slippage between them.

[0077] In some embodiments, two fixing components 700 are provided, and the two fixing components 700 are located on both sides of the support 310 along the X direction.

[0078] To ensure relative stability between the ballast assembly 320 and the support seat 310 during the rotation of the worktable 200, in some embodiments, the ballast body 321 has a positioning hole 3211 and an insertion groove 3212, with the extension direction of the positioning hole 3211 perpendicular to the extension direction of the insertion groove 3212. The support seat 310 is provided with a positioning pin that can pass through the positioning hole 3211. The insertion assembly 800 includes an insertion drive 810 and an insertion member 820. The insertion drive 810 is located on the worktable 200, and the insertion member 820 is located at the output end of the insertion drive 810. The insertion drive 810 is used to drive the insertion member 820 to move between the insertion position and the release position. The insertion member 820 in the insertion position is inserted into the insertion groove 3212. This structural arrangement achieves three-dimensional positioning of the support seat 310 and the ballast assembly 320, thereby preventing relative movement between them and improving welding accuracy. When the worktable 200 is in the first initial position, the positioning pin extends along the Z direction and the connector 820 moves along the X direction.

[0079] The bearing seat 310 provides support for the bearing body, spring, and crimping member. The bearing body has a bearing groove and a crimping groove that connects to the bearing groove. The bearing groove is used to place the outer shell 1000. The crimping member is slidably disposed in the crimping groove and can move between the crimping position and the separation position. The crimping member in the crimping position can press against the outer shell 1000. The spring is used to stop the crimping member in the crimping position.

[0080] Example 2

[0081] This embodiment also provides a welding method applied to the multi-angle welding apparatus in the above-described solution. The welding method includes the following steps:

[0082] The carrier assembly 300, containing the rotating shaft 4000 and the limiting member 3000, is placed on the worktable 200. The worktable 200 rotates to a first position, and the welding component 400 welds the first welding area H1 between the limiting member 3000 and the rotating shaft 4000. The worktable 200 rotates to a second position, and the welding component 400 welds the second welding area H2 between the limiting member 3000 and the rotating shaft 4000. The worktable 200 rotates to a first initial position, and the welding component 400 welds the third welding area H3 between the limiting member 3000 and the rotating shaft 4000.

[0083] By using the above method, automatic welding of the three welding areas between the limiting component 3000 and the rotating shaft 4000 is achieved, which improves welding efficiency and increases the product yield.

[0084] Specifically, before welding, the disk 2000 is fixedly connected to the rotating shaft 4000, and the rotating shaft 4000 is rotatably positioned within the outer casing 1000 to form the first finished product. The welding method includes the following steps:

[0085] Step 1: Place the first finished product on the support 310 and fix it with the crimping component.

[0086] Step 2: Then place the ballast assembly 320 on the bearing seat 310, with the positioning pin passing through the positioning hole 3211.

[0087] Step 3: Place the limiting member 3000 on the rotating shaft 4000, and the positioning protrusion 3231 passes through the intermediate groove 3200, and the positioning protrusion 3231 positions the limiting member 3000 in the axial direction of the rotating shaft 4000.

[0088] Step 4: Then, rotate the disc 2000 so that the disc 2000 is in a closed state relative to the outer shell 1000. At this time, the first limiting surface 1100 and the second limiting surface 3100 are in contact.

[0089] Step 5: Place the vehicle assembly 300 together with the outer shell 1000, the disc 2000 and the limiting member 3000 on the worktable 200.

[0090] Step 6: Secure the support 310 to the worktable 200 using the fixing component 700.

[0091] Step 7: Rotate the worktable 200 clockwise to the first position, so that the first welding area H1 faces upward and is directly opposite the welding part 400. The welding part 400 welds the limiting part 3000 and the rotating shaft 4000 in the first welding area H1. Rotate clockwise 45° to the first position.

[0092] Step 8: Rotate the worktable 200 counterclockwise to the second position, so that the second welding area H2 faces upward and is directly opposite the welding part 400. The welding part 400 welds the limiting part 3000 and the rotating shaft 4000 in the second welding area H2. Rotate counterclockwise 90° to the second position.

[0093] Step Nine: Remove the ballast assembly 320, causing the positioning protrusion 3231 to be pulled out of the intermediate groove 3200, thereby exposing the third welding area H3. Specifically, the ballast assembly 320 is clamped by the clamping assembly 570, and the ballast assembly 320 is transferred to the adjacent recycling position by the pressing drive assembly of the pressing assembly 500, so that the ballast assembly 320 enters the next cycle. That is, the ballast assembly 320 can be reused and ballasted on the bearing seat 310. In step nine, after the ballast assembly 320 is removed from the limiting member 3000 that is being welded, the next limiting member 3000 is ballasted.

[0094] Step 10: Rotate the worktable 200 clockwise to the third position, so that the third welding area H3 faces upward and is directly opposite the welding part 400. Rotate clockwise 45° to the third position.

[0095] Step 11: Welding component 400 to the limiting component 3000 and the rotating shaft 4000 in the third welding area H3.

[0096] Step 12: Press the disc 2000 against the pressing component 500, causing the disc 2000 to rotate downwards so that the fourth welding area H4 faces upwards and is directly opposite the welding part 400. Specifically, the pressing component 500 presses the disc 2000, causing the disc 2000 to rotate downwards by 45°.

[0097] Step 13: Welding component 400 to the fourth welding area H4, where the limiting component 3000 and the rotating shaft 4000 are welded.

[0098] Step Fourteen: Push the disc 2000 with the push assembly 600 to rotate the disc 2000 upwards by 45° and reset it.

[0099] Step 15: Remove the carrier assembly 300. After welding the limiting component 3000, the second finished product is formed.

[0100] After the disc 2000 is reset, it is easier to remove the material, improving material handling efficiency. Of course, in other embodiments, step fourteen can be omitted depending on the specific structure of the product, and material can be removed directly.

[0101] In step two, after placing the carrier assembly 300 on the workbench 200, the ballast assembly 320 can be confined in the Z direction to the bearing seat 310 by the plug-in assembly 800. Specifically, the plug-in member 820 is plugged into the plug-in slot 3212. In this embodiment, in step ten, the plug-in member 820 needs to be pulled out of the plug-in slot 3212.

[0102] When welding the second welding area H2, after removing the ballast assembly 320, the obstruction between the second welding area H2 and the weldment 400 is reduced, making welding easier.

[0103] In other embodiments, steps nine and ten can be interchanged. That is, when welding the third welding area H3, the ballast assembly 320 is removed, so that the ballast assembly 320 remains stationary when welding the second welding area H2, thereby making the relative position accuracy of the limiting member 3000 and the rotating shaft 4000 higher.

[0104] Furthermore, since the shape of the third welding area H3 is U-shaped, during the welding process, the limiting member 3000 is prone to twisting relative to the rotation axis 4000 when welding the bottom of the U-shape of the third welding area H3. This causes relative twisting between the first limiting surface 1100 and the second limiting surface 3100, resulting in them no longer being parallel and affecting the limiting accuracy of the limiting member 3000. Therefore, in this embodiment, the method of welding the first welding area H1 and the second welding area H2 first, and then welding the third welding area H3, can limit the positions of the two ends of the limiting member 3000 relative to the axial direction of the rotation axis 4000, avoiding the twisting of the limiting member 3000 relative to the rotation axis 4000 during the welding of the third welding area H3. This improves the relative positional accuracy between the limiting member 3000 and the rotation axis 4000, thereby ensuring the limiting accuracy of the limiting member 3000.
