Description

Technical Field

[0001] This utility model is a wire feeder, belonging to the field of laser processing. Background Technology

[0002] When laser processing is used to clad the surface of a workpiece, metal wires are required. In the past, the cladding wires were usually fed manually. In particular, stainless steel wires are hard and have a large bending radius, making it difficult to feed them into the laser head. This not only increases the labor intensity of the operators, but also makes it difficult to control the wire feeding angle and speed. The wire feeding direction is also difficult to align with the focal point of the focusing lens, which directly affects the quality of the laser cladding on the workpiece surface.

[0053] The wire feeding assembly 3 includes a first fixed base 31 with an L-shaped structure. The horizontal part of the first fixed base 31 is installed at the front end of the second straightening wheel base 23.

The two bolt adjustment handles 32 are symmetrically threaded to the front end of the vertical part of the first fixed base 31, and the bolt adjustment handles 32 pass through the vertical part of the first fixed base 31. The rear ends of the two bolt adjustment handles 32 are respectively movably connected to the outer front end of the two U-shaped groove plates 36.

The U-shaped groove plates 36 are rotatably connected to the second straightening wheel base through the movable hinges 35.

[0054] Two U-shaped groove plates 36 are rotatably connected to two movable hinges 35 respectively. The U-shaped groove plates 36 provide a mounting carrier for the first deep groove ball bearings 34. The two first deep groove ball bearings 34 are rotatably connected inside the two U-shaped groove plates 36 respectively. The first deep groove ball bearings 34 extend out of the rear side of the U-shaped groove plates 36. The two first deep groove ball bearings 34 are located radially outside the two guide wheels 33 respectively. The two guide wheels 33 are arranged vertically. The two guide wheels 33 and the two first deep groove ball bearings 34 are used in conjunction to perform mechanical wire feeding operation.

[0055] The wire feeding power assembly 6 includes a drive device, with a reducer 62 mounted on the lower end of the drive device. The output shaft of the drive device is connected to the input shaft of the reducer 62. The drive device provides driving force. The drive device can be a servo motor 61. The reducer 62 reduces the driving force. A hollow seat 65 is located at the lower end of the reducer 62. The hollow seat 65, located on the lower side of the second fixed plate 24, is mounted on the left end of the second straightening wheel base 23. The hollow seat 65 provides a mounting carrier for components such as the reducer 62. A rotating shaft 66 is located inside the hollow seat 65. The rotating shaft 66 provides a mounting carrier for components such as the second spur bevel gear 68. The left end of the rotating shaft 66 is rotatably connected to the hollow seat 65 through the second deep groove ball bearing 661, and the right end of the rotating shaft 66 is rotatably connected to the second straightening wheel base 23 through the third deep groove ball bearing 662.

[0056] A second spur bevel gear 68 is fitted onto the outer surface of the rotating shaft 66, causing the rotating shaft 66 to rotate. A first spur bevel gear 67 meshes with the upper left end of the second spur bevel gear 68, and the upper end of the first spur bevel gear 67 is connected to the output shaft of the reducer 62. The second spur bevel gear 68 rotates through the first spur bevel gear 67. A second spur gear 64, located to the right of the second spur bevel gear 68, is then fitted onto the outer surface of the rotating shaft 66. The two first spur gears 63 rotate synchronously through the second spur gear 64, and the two gears located in the hollow seat 6... The first spur gear 63 inside 5 is symmetrically meshed on the rear end of the second spur gear 64, and the shafts of the two first spur gears 63 are rotatably connected to the left end of the second straightening wheel base 23. The shafts of the two first spur gears 63 pass through the second straightening wheel base 23 and are detachably connected to the two guide wheels 33 respectively by a butterfly locking screw. The first spur gear 63 causes the corresponding guide wheel 33 to rotate. The annular end face of the two guide wheels 33 is recessed inward to form a groove 331. The groove 331 restricts the movement of the wire. The groove 331 can be a V-groove or an annular groove.

[0057] The guide nozzle assembly 5 includes a first mounting base 233, which is located above the upper guide wheel 33 and positioned at the right end of the second straightening wheel base 23. The first mounting base 233 provides a mounting carrier for the first guide nozzle 232 and mounts the first guide nozzle 232 inside the first mounting base 233. The upper and lower ends of the first guide nozzle 232 extend out of the upper and lower sides of the first mounting base 233, respectively. The first guide nozzle 232 guides the wire between the upper guide wheel 33 and the upper first deep groove ball bearing 34. The second mounting base 234, located between the two guide wheels 33, is positioned at the right end of the second straightening wheel base 23 and provides a mounting carrier for the second guide nozzle 235.

[0058] The second guide nozzle 235 is installed inside the second mounting base 234, with its upper and lower ends extending out of the upper and lower sides of the second mounting base 234, respectively. The second guide nozzle 235 is positioned between the two first deep groove ball bearings 34. Through the second guide nozzle 235, the wire is guided from between the upper guide wheel 33 and the upper first deep groove ball bearing 34 into between the lower guide wheel 33 and the lower first deep groove ball bearing 34. The third mounting base 236, located below the lower guide wheel 33, is positioned on the second straightening wheel base. On the right end of seat 23, the third mounting seat 236 provides a mounting carrier for the third guide nozzle 237. The third guide nozzle 237 is then installed in the third mounting seat 236, with the upper and lower ends of the third guide nozzle 237 extending out of the upper and lower sides of the third mounting seat 236, respectively. The center lines of the first guide nozzle 232, the second guide nozzle 235, and the third guide nozzle 237 coincide. The wire is guided out from between the lower guide wheel 33 and the lower first deep groove ball bearing 34 through the third guide nozzle 237.

[0059] Before use, the filament is first drawn out from the rubber hose, and then the drawn filament is passed through the first straightening wheel assembly 1 formed by multiple first straightening wheels 12. At this time, multiple first straightening wheels 12 are attached to both the left and right ends of the filament. At the same time, the first adjusting handle knob 11 is rotated according to the filament diameter data. Since the first adjusting handle knob 11 is threadedly connected to the corresponding first fixing plate 14, the first adjusting handle knob 11 rotates and moves left and right at the same time. With the assistance of the first compression spring 151, the corresponding first guide block 15 moves left and right along the corresponding first mounting groove 131, and the corresponding first straightening wheel 12 moves left and right. The same steps as above can be used to adjust the left and right positions of the first straightening wheel 12 at different positions, so as to press the left and right ends of the filament. At this time, the two adjacent first straightening wheels 12 on the left and right sides are in tangential contact with the filament.

[0060] The filament is drawn out from the lower end of the first straightening wheel assembly 1, and then the drawn filament is passed through the second straightening wheel assembly 2 formed by multiple second straightening wheels 22. At this time, multiple second straightening wheels 22 are attached to both the front and rear ends of the filament. Then, the second adjusting handle knob 21 is rotated according to the filament diameter data. Since the second adjusting handle knob 21 is threadedly connected to the corresponding second fixing plate 24, the second adjusting handle knob 21 moves back and forth while rotating. With the assistance of the second compression spring 251, the corresponding second guide block 25 moves back and forth along the corresponding second mounting groove 231, so that the corresponding second straightening wheel 22 moves back and forth.

[0061] Similar to the steps described above, the front and rear positions of the second straightening rollers 22 at different locations can be adjusted to press the front and rear ends of the wire. At this time, the two adjacent second straightening rollers 22 on the front and rear sides are in tangential contact with the wire, achieving straightening treatment of the wire in four directions: left, right, front, and rear. In particular, the wire with infinitely equal segments and deformation can be fully corrected, effectively reducing the probability of the wire being twisted due to mechanical wire feeding factors, effectively reducing the probability of defects in welding and other work, and effectively ensuring the wire feeding effect and work quality. In addition, it is suitable for adjusting the clamping distance of wires of different sizes and specifications. At this time, different specifications of V-groove bearings can be replaced to further accommodate the use of wires of various diameters, expanding the wire feeding diameter to 0.3mm-3.0mm. When feeding fine wires, it can prevent the wire from breaking or twisting. When feeding thick wires, it can straighten the wire and effectively pull it down, thereby achieving effective wire feeding operations for wires made of rare metal materials or welding manufacturing operations of special products.

[0062] The wire is drawn out from the lower end of the second straightening wheel assembly 2, and then the drawn wire is passed through the first wire guide nozzle 232 and introduced into the groove 331 of the upper wire guide wheel 33. At this time, the wire part is at the front end of the groove 331. At the same time, the upper bolt adjustment handle 32 is rotated. Since the bolt adjustment handle 32 is threadedly connected to the first fixed base 31, the bolt adjustment handle 32 rotates and moves backward at the same time, thereby applying a backward thrust to the upper front end of the upper U-shaped groove plate 36, so that the upper U-shaped groove plate 36 swings backward around the corresponding movable hinge 35, thereby causing the upper first deep groove ball bearing 34 to move backward, thereby making a squeezing contact with the front end of the wire.

[0063] The wire is drawn out from the groove 331 of the upper guide wheel 33, and then the drawn wire is passed through the second guide nozzle 235 and introduced into the groove 331 of the lower guide wheel 33. At this time, the wire part is at the front end of the groove 331. At the same time, the lower bolt adjustment handle 32 is rotated. Since the bolt adjustment handle 32 is threadedly connected to the first fixed base 31, the bolt adjustment handle 32 rotates and moves backward at the same time, thereby applying a backward thrust to the lower front end of the lower U-shaped groove plate 36, so that the lower U-shaped groove plate 36 swings backward around the corresponding movable hinge 35, thereby causing the lower first deep groove ball bearing 34 to move backward, thereby making a squeezing contact with the front end of the wire.

[0064] The wire is drawn out from the groove 331 of the lower guide wheel 33, and then the drawn wire is passed through the third guide nozzle 237. The two first deep groove ball bearings 34 make squeezing contact with the wire, and with the corresponding groove 331, the wire is constrained and can only move freely in one direction. This ensures the straightness of the wire movement, effectively reduces the probability of the wire slipping during the wire feeding process, and effectively guarantees the wire feeding effect and working effect.

[0065] Furthermore, if the wire is completely within the groove 331, the wire cannot contact the first deep groove ball bearing 34, thus preventing mechanical transmission of the wire. Additionally, the guide wheel 33 can be made of a high-hardness alloy material with a heat-treated surface to enhance hardness and improve wear resistance. The first guide nozzle 232, the second guide nozzle 235, and the third guide nozzle 237 are all made of copper group materials. Copper has high mechanical strength and good ductility, and relatively low frictional resistance. The installation positions of the first guide nozzle 232, the second guide nozzle 235, and the third guide nozzle 237 are linearly distributed, ensuring smooth wire passage and providing excellent guidance. When using wires of different diameters, it is necessary to replace the first guide nozzle 232, the second guide nozzle 235, and the third guide nozzle 237 with different sizes and specifications.

[0066] In operation, the servo motor 61 is started, and with the assistance of the reducer 62, the first spur bevel gear 67 rotates. Since the first spur bevel gear 67 meshes with the second spur bevel gear 68, the rotation of the first spur bevel gear 67 will cause the second spur bevel gear 68 to rotate, which in turn will cause the rotating shaft 66 to rotate, thereby causing the second spur gear 64 to rotate. Since the second spur gear 64 meshes with the two first spur gears 63, the rotation of the second spur gear 64 will simultaneously cause the two first spur gears 63 to rotate synchronously, thereby causing the two guide wheels 33 to rotate synchronously. With the assistance of the two first deep groove ball bearings 34, the wire is pushed by compression, thus completing the wire feeding operation. This achieves mechanical unidirectional wire feeding, reduces labor intensity, effectively reduces the probability of deviation between the fed wire and the laser focus, and effectively ensures the wire feeding effect and work quality.

[0067] Alternatively, a servo motor 61 and a reducer 62 can be used to make the first spur bevel gear 67 rotate in the opposite direction. With the assistance of the second spur bevel gear 68, the rotating shaft 66, the second spur gear 64, and the two first spur gears 63, the two guide wheels 33 can rotate synchronously in the opposite direction to achieve a high-precision wire unwinding and resetting operation. The wire can be retracted to the wire feeding starting point or a designated position, which is convenient for defective section removal and process adjustment. There is no need to cut off the entire section of wire, which greatly reduces the waste of rare metal materials.

[0068] Example 2, please refer to Figure 1 , Figure 13 and Figure 14 The real-time wire feeding speed monitoring component 4 includes a straight plate 48, which is installed on the lower end of the second straightening wheel base 23. The straight plate 48 provides a mounting carrier for components such as the second fixed base 44. The second fixed base 44 is set on the right end of the straight plate 48. The second fixed base 44 provides a mounting carrier for components such as the encoder 43. The encoder 43 is then installed on the rear end of the second fixed base 44, and the input end of the encoder 43 passes through the second fixed base 44. The encoder 43 is used to detect the wire feeding speed in real time. The encoder guide wheel 47 is set on the front end of the input end of the encoder 43. The input end of the encoder 43 is rotated by the encoder guide wheel 47. The encoder guide wheel 47 can be made of polyurethane.

[0069] A third mounting groove is formed by a rearward recess at the front end of the second fixed base 44, and the third mounting groove passes through the second fixed base 44. The third mounting groove provides mounting space for components such as the third guide block 45. The third guide block 45, which extends out of the front side of the third mounting groove, is slidably connected in the third mounting groove. The third guide block 45 provides a mounting carrier for the V-groove follower bearing 46. The V-groove follower bearing 46, located on the right side of the encoder guide wheel 47, is rotatably connected to the front end of the third guide block 45. The third wire guide nozzle 237 is located on the upper side of the gap formed between the V-groove follower bearing 46 and the encoder guide wheel 47. The V-groove follower bearing 46 applies a leftward thrust to the wire.

[0070] The third compression spring 444 is installed on the left end of the third guide block 45, and the left end of the third compression spring 444 is connected to the left wall inside the third mounting groove. The third compression spring 444 applies a rightward push force to the third guide block 45. The bolt plunger knob 441 is threaded onto the right end of the second fixed base 44, and the bolt plunger knob 441 passes through the second fixed base 44 and is pressed against the right end of the third guide block 45. The bolt plunger knob 441 applies a leftward push force to the third guide block 45. The bolt plunger knob 441 and the third compression spring 444 work together to adjust the left and right positions of the third guide block 45 and the V-groove follower bearing 46.

[0071] The hard limit 442, located on the left side of the third mounting slot and behind the encoder guide wheel 47, is installed on the front end of the second fixed base 44. The second fixed base 44 provides a mounting carrier for the adjusting screw 443. The two adjusting screws 443 are symmetrically threaded to the left end of the hard limit 442. The rod of the adjusting screw 443 passes through the hard limit 442 and is pressed against the left end of the third guide block 45. The two adjusting screws 443 work together to restrict the left side position of the third guide block 45, thereby protecting the encoder guide wheel 47.

[0072] The fourth mounting base 42 is set on the lower end of the straight plate 48. The fourth mounting base 42 provides a mounting carrier for the fourth guide wire nozzle 41 and installs the fourth guide wire nozzle 41 in the fourth mounting base 42. The upper and lower ends of the fourth guide wire nozzle 41 extend out of the upper and lower sides of the fourth mounting base 42, respectively. The fourth guide wire nozzle 41 is located directly below the gap formed between the V-groove follower bearing 46 and the encoder guide wheel 47. The center line of the third guide wire nozzle 237 and the center line of the fourth guide wire nozzle 41 coincide.

[0073] After the wire is drawn out from the third guide nozzle 237, it is then passed between the V-groove follower bearing 46 and the encoder guide wheel 47, and through the fourth guide nozzle 41. At the same time, the bolt plunger knob 441 is rotated. Since the bolt plunger knob 441 is threadedly connected to the second fixed base 44, the bolt plunger knob 441 rotates and moves left and right at the same time. With the assistance of the third compression spring 444, the third guide block 45 moves left and right, which in turn causes the V-groove follower bearing 46 to move left and right, thereby achieving the pressing of the left and right ends of the wire.

[0074] At the same time, the adjusting screw 443 is rotated. Since the adjusting screw 443 is threadedly connected to the hard limit 442, the adjusting screw 443 rotates and moves left and right at the same time, thereby adjusting the left and right position of the adjusting screw 443, thereby limiting the leftward limit position of the third guide block 45, effectively preventing damage to the encoder guide wheel 47, and thus activating the protection function.

[0075] Because the V-groove follower bearing 46 and the encoder guide wheel 47 are in a pressing state on the wire, the encoder guide wheel 47 will rotate during the wire feeding process. At this time, the encoder 43 records and calculates the rotation data of the encoder guide wheel 47, thereby feeding back the real-time wire feeding speed. Finally, the wire is fed out through the fourth wire guide nozzle 41, thus completing the entire wire feeding process. This enables real-time monitoring of the wire feeding speed, improves the wire feeding accuracy, effectively reduces the wire waste rate, and can also display the wire feeding speed on the human-machine interface, making the wire feeding speed visible.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
