Description

Technical Field

[0001] This utility model relates to the field of laser soldering technology, and in particular to a multi-channel wire feeding device for a welding equipment. Background Technology

[0002] Laser soldering equipment typically consists of a drive assembly, a soldering iron assembly (soldering tool), and a wire feeding assembly; in Chinese patent publication number CN115533256B, the laser soldering equipment is equipped with a flux device and a wire feeding device.

[0003] However, in actual operation of laser soldering equipment, such as during continuous soldering or spot welding along a certain trajectory, the wire outlet at the wire feeding assembly may interfere with the components on the circuit board. This requires adjustment of the position of the wire outlet or the position of the soldering tool, which increases the control device of the corresponding component and the adjustment difficulty during the operation of the laser soldering equipment.

[0004] In summary, how to enable continuous welding with laser devices when the wire feeding assembly and wire outlet encounter obstacles during operation has become a research focus for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to enable the laser device to continue welding when the wire feeding assembly encounters a malfunction during operation;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to a multi-path wire feeding device for welding equipment, comprising: a base; a laser welding head disposed on the base and adapted to emit a laser beam vertically downwards; at least two wire feeding assemblies disposed around the laser welding head; a lifting assembly, the fixed end of which is connected to the base and the movable end of which is movably connected to the corresponding laser welding head; and wire outlets obliquely disposed at the outlet of each of the wire feeding assemblies. When the lifting assembly adjusts the corresponding wire outlets to the same height, the center extension lines of the multiple wire outlets intersect at a single point, and this point is located on the center line of the laser beam.

[0008] Furthermore, the lifting assembly includes: an electric slide fixed to the base mounting plate; and a lifting plate fixed to the movable end of the electric slide.

[0009] Furthermore, a slide rail is vertically arranged on the mounting plate and on one side of the electric slide table; an extension block is provided on one side of the lifting plate extending toward the slide rail; and a slider that cooperates with the slide rail is fixed at the bottom of the extension block.

[0010] Furthermore, a circumferential adjustment component is provided between the movable end of the lifting component and the wire feeding component for adjusting the circumferential position of the wire feeding component around the center line of the laser beam; the circumferential adjustment component includes: a horizontally arranged adjustment plate, the inner side of which has an arc-shaped groove, the center of which is located on the center line of the laser beam; an arc-shaped block, which is slidably disposed in the arc-shaped groove; an arc-shaped adjustment seat, which is disposed at the bottom of the adjustment plate; and a first locking member, which passes through the arc-shaped block and the arc-shaped groove and is connected to the arc-shaped adjustment seat. Rotating the first locking member moves the arc-shaped adjustment seat together with the arc-shaped block within the arc-shaped groove and locks it in place.

[0011] Furthermore, the wire feeding assembly and the lifting assembly are adjustablely connected via a fine-tuning component.

[0012] Furthermore, the fine-tuning component includes: a reversing plate having a vertical surface connected to the lifting plate, a horizontal surface connected to the Y-axis module, and reinforcing ribs connecting the horizontal and vertical surfaces; and an X-axis module disposed at the bottom of the Y-axis module.

[0013] Furthermore, the vertical sidewall of the arc-shaped adjusting seat is provided with an inclined slide rail, the length direction of which is parallel to the center extension line of the wire outlet; a connecting part for connecting the wire feeding assembly is provided on the connecting part, and an inclined slider matching the inclined slide rail is provided on the connecting part; an inclined adjusting hole is formed on the connecting part, the length direction of which is parallel to the length direction of the inclined slide rail; and a second locking member passes through the inclined adjusting hole and is connected to the arc-shaped adjusting seat.

[0014] The beneficial effects of this utility model are as follows: In this utility model, multiple wire feeding components are arranged around the laser welding head. Each wire feeding component is connected to the base through a lifting component. When the laser welding device is working, each lifting component controls the corresponding wire feeding component to rise and fall, so that one or more welding wires are placed under the same laser welding head. This provides a logical sequence of individual wire feeding welding, synchronous wire feeding welding, or sequential combination wire feeding welding, enhancing the flexible processing capability of welding. When one of the wire feeding components encounters an obstacle during the working process, the wire feeding component is raised, and another wire feeding component is lowered through the lifting component to participate in welding, so that the laser device can perform continuous welding.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0026] Example 1

[0027] like Figure 1 , 2As shown in Figures 3 and 5, this utility model is a multi-channel wire feeding device for welding equipment, comprising: a base 1; a vertical laser welding head 2 fixed on the base 1, which emits a laser beam 21 vertically downwards during operation; two wire feeding assemblies 3 concentrically arranged with the laser welding head 2; each wire feeding assembly 3 is connected to the base 1 through a corresponding lifting assembly 4, which controls the independent lifting movement of the corresponding wire feeding assembly 3; and a wire outlet 5 is located at the outlet of the wire feeding assembly 3, which is used to make the welding wire fed out by the wire feeding assembly 3 form a certain angle with the laser beam 21 emitted by the laser welding head 2, so as to facilitate the melting and welding of the welding wire.

[0028] Before welding with this device, it is necessary to ensure that when the two wire nozzles 5 in the left and right positions are controlled by the lifting component 4 to be at the same height, the center extension lines of the wire nozzles 5 intersect at one point, and this point is located on the center line of the laser beam 21, and the distance between the end of the wire nozzle 5 and the center line of the laser beam 21 is consistent; the above-mentioned position adjustment setting of the wire nozzles 5 is achieved by the fine adjustment component 6 in the following embodiment 3.

[0029] During the welding process, for example, when the wire outlet 5 on the left side is obstructed by components, the wire feeding assembly 3 and the wire outlet 5 are raised by the lifting assembly 4 on the left side, and the wire feeding assembly 4 and the wire outlet 5 on the right side are lowered by the lifting assembly 4 on the right side. The end of the welding wire on the right side is located at the laser beam 21. The welding device completes obstacle avoidance and realizes continuous welding of the device.

[0030] In addition, during the welding process, when reinforcement is required at the weld joint, the wire feeding assembly 3 and wire outlet 5 on both sides are controlled by the corresponding lifting assembly 4 to be in the working position. In this way, both welding wires are heated by the laser beam 21 for welding, thus strengthening the weld joint.

[0031] Furthermore, during the welding process, when the welding wire on the left wire feeding assembly 3 is exhausted, the left wire feeding assembly 3 rises while the right wire feeding assembly 3 descends to feed the welding wire, thus extending the welding length of the welding wire.

[0032] The wire feeding assembly 3 described above is a conventional technology and will not be described in detail in this application.

[0033] To illustrate the specific structure of the lifting assembly in Embodiment 1, the present invention uses the lifting assembly 4, which includes: an electric slide 41 fixed on the mounting plate 11 of the base 1; and a lifting plate 42 fixed to the movable end of the electric slide 41.

[0034] The lifting assembly 4 adopts an electric slide table 41, which can realize the rapid lifting of the lifting plate 42, that is, the rapid lifting of the wire feeding assembly 3 together with the wire outlet nozzle 5. During the rapid switching of the two wire feeding assemblies 3, it is ensured that no welding breaks occur during the welding process.

[0035] In Embodiment 1, in order to ensure the movement accuracy of the lifting plate 42 during the lifting process, the present invention adopts a slide rail 43 vertically arranged on the mounting plate 11 and located on one side of the electric slide table 41; an extension block 44 is provided on one side of the lifting plate 42 extending towards the slide rail 43; and a slider that cooperates with the slide rail 43 is fixed at the bottom of the extension block 44.

[0036] In addition to the lifting plate 41 being controlled by the electric slide table 41 for lifting and lowering, the lifting plate 42 is guided by the slider and slide rail 43 to further ensure the motion accuracy of the lifting plate 42 during the lifting and lowering process.

[0037] Example 2

[0038] like Figure 1 , 2 As shown in Figures 3, 4, and 6, based on Embodiment 1, a circumferential adjustment component 7 is further added between the lifting assembly 4 and the wire feeding assembly 3. The circumferential adjustment component 7 includes: a horizontally arranged adjustment plate 71, which can be connected to the lifting plate 42 of the lifting assembly 4 or to the movable end of the X-axis module in Embodiment 3. An arc-shaped groove 72 is provided on the inner side of the adjustment plate 71, and the center of the arc-shaped groove 72 is located on the center line of the laser beam 21; an arc-shaped block 73, which is slidably disposed in the arc-shaped groove 72; an arc-shaped adjustment seat 74, which is disposed at the bottom of the adjustment plate 71; and a first locking member 710, which passes through the arc-shaped block 73 and the arc-shaped groove 72 and is connected to the arc-shaped adjustment seat 74. By rotating the first locking member 710, the arc-shaped adjustment seat 74 together with the arc-shaped block 73 is locked in the arc-shaped groove 72.

[0039] In this embodiment 2, the circumferential adjustment component 7 can adjust the wire feeding component 4 and the wire outlet 5 around the center line of the laser beam 21. That is, the arc block 73 and the arc adjustment seat 74 can move in an arc along the arc groove 72. When adjusted to a suitable position, the arc block 73 and the arc adjustment seat 74 are fixedly connected to the adjustment plate 71 by rotating the first locking member 710, thereby completing the adjustment of the circumferential position of the wire feeding component 3.

[0040] The purpose of the circumferential adjustment of the wire feeding assembly 4 is that when the wire outlet 5 encounters an obstacle, even when the wire outlet 5 is raised to the limit position by the lifting assembly 4, the wire outlet 5 still cannot pass the component. At this time, it is necessary to adjust the circumferential position of the wire feeding assembly 3 to avoid the component by the wire outlet 5 and realize the continuous welding of the device.

[0041] Example 3

[0042] like Figure 1 , 2As shown in Figures 3, 4, and 7, based on Embodiment 1 or Embodiment 2, in order to adjust the position of the wire feeding assembly 3 and the wire outlet nozzle 5 before welding, this utility model adopts an adjustable connection between the wire feeding assembly 3 and the lifting assembly 4 through the fine-tuning assembly 6.

[0043] In this embodiment, to illustrate the specific structure of the fine-tuning component 6, the present invention uses the fine-tuning component 6, which includes: a reversing plate 61, the reversing plate 61 having a vertical surface 611 connected to the lifting plate 42, a horizontal surface 612 connected to the Y-axis module 62, and a reinforcing rib 613 connecting the horizontal surface 612 and the vertical surface 611; and an X-axis module 63 disposed at the bottom of the Y-axis module 62.

[0044] The reversing plate 61 can connect the vertical lifting plate 42 and the top of the horizontal Y-axis module 62. The Y-axis module 62 and the X-axis module 63 realize the two-axis linear adjustment of the wire feeding assembly 3 and the wire outlet nozzle 5 in the horizontal direction, thereby adjusting the distance between the end of the wire outlet nozzle 5 and the center line of the laser beam 21 in the X-axis direction and the Y-axis direction. The Y-axis module 62 and the X-axis module 63 specifically adopt a manual feed screw type slide structure. By rotating the screw in the manual feed screw type slide, the two-axis linear adjustment of the wire feeding assembly 3 and the wire outlet nozzle 5 in the horizontal plane can be realized.

[0045] Based on Embodiment 3, after the horizontal two-axis linear adjustment of the wire feeding assembly is achieved by the fine-tuning component 6, the intersection of the center extension lines of the two wire outlet nozzles 5 can be located on the center line of the laser beam 21. However, it cannot be guaranteed that the distance between the two wire outlet nozzles 5 and the center line of the laser beam is consistent, that is, it cannot be guaranteed that the two wire outlet nozzles 5 are symmetrically arranged with respect to the center line of the laser beam 21. In order to solve the above problems, this utility model adopts an inclined slide rail 75 provided on the vertical side wall of the arc-shaped adjustment seat 74, the length direction of the inclined slide rail 75 is parallel to the center extension line of the wire outlet nozzles 5; a connecting part 76 for connecting the wire feeding assembly 3, the connecting part 76 is provided with an inclined slider 77 matching the inclined slide rail 75; an inclined adjustment hole 78 is opened on the connecting part 76, the length direction of which is parallel to the length direction of the inclined slide rail 75; and a second locking member 79 passes through the inclined adjustment hole 78 and is connected to the arc-shaped adjustment seat 74.

[0046] The arc-shaped adjustment seat 74 and the connecting part 76 are connected by an inclined slide rail 75 and an inclined slider 77. The connecting part 76 is provided with a second locking member 79. When the intersection of the center extension lines of the two wire outlet nozzles 5 is located on the center line of the laser beam 21, the two wire outlet nozzles 5 are symmetrically arranged with the center line of the laser beam 21 by adjusting the relative positions of the arc-shaped adjustment seat 74 and the connecting part 76. Then, rotating the second locking member 79 can lock the connecting part 76 and the arc-shaped adjustment seat 74, thus completing the final adjustment of the position of the wire feeding assembly 3 and the wire outlet nozzles 5.

[0047] Working principle:

[0048] Before welding, the two wire nozzles 5 are adjusted to be symmetrically set with the laser beam 21 as the center line by adjusting the Y-axis module 62, X-axis module 63, oblique slider 77, and oblique slide rail 75. After the adjustment is completed, during the welding process, the lifting component 4 can drive the corresponding wire nozzle 5 to lift and lower to achieve the barrier, or the circumferential adjustment component 7 can adjust the circumferential position of the wire nozzle 5 to achieve the barrier, thus realizing continuous welding of the device.

[0049] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
