DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Reference Figures 1 to 15 :

[0038] An inductor automatic winding laser spot welding integrated machine, comprising a base 1, a winding machine 2 and a spot welding machine 3 installed on the base 1, and a 1 A placement seat 4 for placing an inductor is provided on the placement seat 4, and a plurality of rectangular positioning grooves 41 are arranged on the placement seat 4, and the positioning grooves 41 are evenly spaced along the length direction of the placement seat 4, and a profiling hole 42 extending vertically downward is arranged in each positioning groove 41, and the profiling hole 42 has the same cross section as the inductor, and wire grooves 421 are arranged on both sides of the profiling hole 42; the placement seat 4 is provided with a support rod 43 in each profiling hole 42, and the support rod 43 is elastically installed in the placement seat 4, and the inductor entering the profiling hole 42 is located at the top of the support rod 43; A lifting frame 11 and a first linear drive 12 for driving the lifting frame 11 to move in a vertical direction are provided on the seat 1. The lifting frame 11 is provided with welding windows 111 having the same number as the positioning slots 41. The welding windows 111 are respectively located directly above each positioning slot 41. A cross bar 112 is provided in the middle of the welding windows 111. A downward pressing rod 113 extending vertically downward is provided at the center of the cross bar 112. When the lifting frame 11 is moved downward and inserted into the positioning slot 41, the downward pressing rod 113 pushes the inductor downward into the contoured hole 42.

[0039] The integrated machine in the present invention includes a base 1, and a winding machine 2 and a spot welding machine 3 installed on the base 1. The winding machine 2 winds the inductor and cuts the wire after winding. The wire after cutting is lifted up to both sides of the pins of the inductor. Then, the wound inductor can be sucked by a mechanical arm with a vacuum suction cup and moved to a placement seat 4. The inductors are inserted one by one into the contoured holes 42 set in the positioning grooves 41 on the placement seat 4 for placement, as shown in FIG. Figure 4 As shown, the placement seat 4 drives the inductor to move to the bottom of the spot welding machine 3, and the spot welding machine 3 is installed on the lifting frame 11. The welding window 111 on the lifting frame 11 can be moved down and inserted into the positioning groove 41 of the placement seat 4 for positioning. The downward pressing rod 113 arranged on the horizontal frame rod 112 located in the middle of the welding window 111 moves the inductor in the profiling hole 42 downward when entering the positioning groove 41, so that the inductor enters the profiling hole 42. As the inductor moves downward in the profiling hole 42, the wire is limited by the wire groove 421 on the side of the profiling hole 42, and is automatically squeezed to a vertical state, and fits on both sides of the inductor pin, as shown in FIG. Fig. 9As shown, the spot welder 3 can then be moved along the lifting frame 11, and the working end of the spot welder 3 spot welds the pins and wires of the inductor in the positioning groove 41 through the welding window 111 to complete the processing of the inductor. The placement seat 4 in this embodiment cooperates with the lifting frame 11 to automatically complete the positioning of the two ends of the wire when the inductor is fully inserted into the contoured hole 42, so that the wire automatically fits with the pins on both sides of the inductor before welding, and the welding position is located in the welding window 111, which is convenient for the spot welder 3 to directly perform spot welding.

[0040] In order to enable the lifting frame 11 to be lifted and lowered to complete the splicing and separation of the lifting frame 11 and the placement seat 4, the following features are specifically set:

[0041] The base 1 is fixedly provided with a first linear drive 12 at both ends of the lifting frame 11 . The lifting frame 11 is installed on the working end of the first linear drive 12 . The working end of the first linear drive 12 is arranged to move in the vertical direction.

[0042] The first linear drive 12 in this embodiment can be a cylinder or an electric push rod. The first linear drive 12 is installed at both ends of the lifting frame 11 to drive the lifting frame 11 to move up and down in the vertical direction, so that the welding window 111 can be inserted into the positioning groove 41 of the placement seat 4 or separated from the placement seat 4.

[0043] In order to enable the spot welding machine 3 to move along the length direction of the lifting frame 11 to accurately spot weld all the inductors, the following features are specifically set:

[0044] A second linear driver 13 is fixedly mounted on the lifting frame 11 . The working end of the second linear driver 13 extends along the length direction of the lifting frame 11 . The spot welder 3 is fixedly mounted on the working end of the second linear driver 13 .

[0045] The lifting frame 11 in this embodiment is provided with a second linear driver 13 for driving the spot welder 3 to move along the length direction of the lifting frame 11. The second linear driver 13 can be a screw slide, etc. The spot welder 3 is located on the working end of the second linear driver 13 and moves. The inductors in the welding windows 111 distributed at equal intervals along the length direction of the lifting frame 11 can be welded in sequence. The second linear driver 13 is installed on the lifting frame 11 to realize the synchronous lifting and lowering of the spot welder 3 and the lifting frame 11, thereby ensuring the uniformity of the welding height of the working end of the spot welder 3.

[0046] In order to achieve the purpose of moving the support rod 43 in the profiling hole 42 so that the inductor can maintain a relative position when it first enters the profiling hole 42 and can continue to move downward under the pressure of the pressing rod 113, the following features are specifically set:

[0047] A sleeve 431 with an opening downward is provided at the bottom of the support rod 43. The sleeve 431 is located in a movable cavity provided below the placement seat 4. The sleeve 431 is sleeved in an insertion cylinder 432 provided on the placement seat 4. A spring 433 is provided in the insertion cylinder 432. The spring 433 elastically connects the sleeve 431 and the insertion cylinder 432. The elastic force of the spring 433 causes the support rod 43 to move upward; the width of the sleeve 431 is greater than the diameter of the support rod 43. The elastic force of the spring 433 causes the sleeve 431 to fit the bottom of the contoured hole 42.

[0048] In the present embodiment, the sleeve 431 at the bottom of each support rod 43 fits the bottom of the contoured hole 42 under the elastic force of the spring 433, and maintains the initial position of the support rod 43 in the contoured hole 42. When the inductor is taken out of the winding machine 2 and placed in the contoured hole 42, the bottom of the inductor fits the top of the support rod 43 to maintain the position of the inductor in the contoured hole 42. Subsequently, when the lifting frame 11 moves downward to cause the pressing rod 113 to press the inductor, the inductor can press the support rod 43 downward. In the process of the inductor entering the contoured hole 42, the wires on both sides are deformed in the wire groove 421 and fit to the pins of the inductor. In the process of the support rod 43 moving downward, the spring 433 is compressed. The cooperation of the sleeve 431 and the insertion tube 432 stabilizes the axial position of the support rod 43, and ensures that the support rod 43 can only move in the vertical direction.

[0049] In order to facilitate the placement of the inductor in the positioning groove 41 of the placement seat 4, the following features are specifically provided:

[0050] A shaft 44 is provided at the top of both ends of the placement seat 4, and the shaft 44 extends along the length direction of the placement seat 4, and a hinge seat 441 is rotatably installed on the shaft 44; a third linear drive 14 is provided on the base 1, and the working end of the third linear drive 14 moves in a horizontal direction perpendicular to the length direction of the placement seat 4, and the hinge seat 441 is fixedly installed on the working end of the third linear drive 14, and the winding machine 2 is fixedly installed at one end of the third linear drive 14, and the spot welding machine 3 is arranged on the moving path of the third linear drive 14; a shell 45 is provided on the outside of the placement seat 4, and the bottom of the shell 45 is suspended, and the base 1 is provided with a support block 15 below the spot welding machine 3, and the placement seat 4 remains vertical when the bottom of the shell 45 is in contact with the bottom of the support block 15; an adjustment block 16 is provided on the side of the base 1 located on the support block 15 facing the winding machine 2, and the positioning groove 41 is horizontally facing the winding machine 2 when the side of the shell 45 is in contact with the top of the adjustment block 16.

[0051] A curved surface extending obliquely downward is provided on one side of the adjusting block 16 facing the supporting block 15 .

[0052] The placement seat 4 in this embodiment is installed on the working end of the third linear drive 14 set on the base 1. The third linear drive 14 can be a screw slide, etc. The third linear drive 14 can drive the placement seat 4 to move. The placement seat 4 is rotatably installed on the hinge seat 441 through the shaft 44. The hinge seat 441 follows the working end of the third linear drive 14 to move toward the side of the winding machine 2, so that the shell 45 is close to the side of the winding machine 2 and fits the adjustment block 16 set on the base 1. The adjustment block 16 lifts the bottom end of the shell 45 and gradually rotates around the axis of the shaft 44 It rotates to a horizontal state so that the positioning slot 41 of the placement seat 4 opens toward the winding machine 2, which facilitates the insertion of the inductor into the contoured hole 42. Then the third linear drive 14 drives the hinged seat 441 to move toward the spot welding machine 3. The placement seat 4 is separated from the adjustment block 16 and then returns to a vertical state with the bottom suspended. When the placement seat 4 is translated to the bottom of the spot welding machine 3, the support block 15 on the base 1 fits the bottom of the shell 45, so the shell 45 cannot rotate around the axis of the shaft rod 44, thereby maintaining a vertical state, which facilitates the downward movement of the lifting frame 11 so that the lifting frame 11 can be inserted into the positioning slot 41.

[0053] In order to facilitate the inductor inserted in the profiling hole 42 to be removed from the profiling hole 42 for unloading, the following features are specifically provided:

[0054] The base 1 is located at the end of the support block 15 away from the adjusting block 16 and is provided with a vertical hanger 17. A horizontal support plate 171 is provided on the top of the hanger 17. When the side of the shell 45 is in contact with the support plate 171, the positioning groove 41 of the placement seat 4 is horizontally oriented to the end away from the winding machine 2. The base 1 is located at the end of the hanger 17 away from the adjusting block 16 and is provided with a collection box 18 with an opening upward; an inner through hole 434 is provided in the support rod 43 of the placement seat 4, and an inner push rod 46 is coaxially provided in the inner through hole 434. The inner push rod 46 moves along the axis of the support rod 43 to push the inductor in the contoured hole 42 out of the placement seat 4 and drop it into the collection box 18.

[0055] After the spot welding machine 3 in this embodiment completes the welding of all the inductors in the placement seat 4, the third linear drive 14 drives the placement seat 4 to move toward the hanger 17, so that the side of the shell 45 away from the winding machine 2 is in contact with the hanger 17, and the shell 45 is rotated around the axis of the shaft rod 44 to a horizontal state, and the positioning groove 41 of the placement seat 4 is horizontally facing the top of the collection box 18. An inner through hole 434 is provided at the axis of the support rod 43 in this embodiment. The inner push rod 46 inserted in the inner through hole 434 can move along the axis direction of the support rod 43 at this time to push out the inductor in the contoured hole 42 and make it fall into the collection box 18 on one side of the hanger 17 for collection, and the unloading can be automatically completed.

[0056] In order to enable the inner push rod 46 to automatically move in the inner through hole 434 and have sufficient force to push out the inductor in the contoured hole 42, the following features are specifically provided:

[0057] All the inner push rods 46 are inserted into the guide holes set at the bottom of the placement seat 4, and the bottom ends of all the inner push rods 46 are fixedly connected to the movable plate 461; a first rack 462 is set on the side of the movable plate 461 away from the winding machine 2, and the teeth on the first rack 462 are evenly spaced along the axial direction of the support rod 43; the placement seat 4 is located on the side away from the winding machine 2 and is fixedly installed with a mounting frame 47, and a gear 471 is rotatably installed on the mounting frame 47, and the axis of the gear 471 is set along the length direction of the placement seat 4, and the gear 471 is meshed with the first rack 462; a second rack 48 is slidably installed on the side of the placement seat 4 away from the winding machine 2, and the second rack 48 is meshed with the gear 471, and the surface of the second rack 48 on the side away from the winding machine 2 is flush with the side of the outer shell 45, and an extension plate 481 perpendicular to the second rack 48 is set on the side of the second rack 48 away from the gear 471.

[0058] In this embodiment, the inner push rod 46 in each support rod 43 passes through the guide hole on the placement seat 4 and is connected to the movable plate 461 at the bottom of the placement seat 4. The first rack 462 on the movable plate 461 and the second rack 48 slidably installed outside the placement seat 4 are both meshed and connected with the gear 471. Therefore, the movement of the second rack 48 can drive the movable plate 461 to move in the axial direction of the support rod 43 to realize the movement of the inner push rod 46. When the shell 45 is in contact with the hanger 17, the shell 45 rotates, so that the second rack 462 on the side of the shell 45 facing the hanger 17 is engaged with the second rack 471. 8 The horizontal extension plate 481 set at the bottom is flipped to a vertical state. As the third linear drive 14 drives the placement seat 4 to move, the extension plate 481 in the vertical state moves to one side of the fitting bracket 17. In the subsequent process in which the third linear drive 14 continues to drive the placement seat 4 to move, the position of the extension plate 481 remains unchanged, thereby causing the gear 471 to rotate, thereby driving the first rack 462 to move in the moving direction of the placement seat 4, and driving the inner push rod 46 to push the inductor in the contoured hole 42 outward, thereby realizing automatic unloading of the inductor.

[0059] In order to ensure that the second rack 48 is located outside the placement seat 4 for stable sliding, the following features are specifically provided:

[0060] At least two vertical guide rods 482 are disposed on the second rack 48 , and the guide rods 482 are inserted into guide sleeves 472 disposed on the mounting frame 47 .

[0061] In this embodiment, the second rack 48 is inserted into the guide sleeve 472 on the mounting frame 47 through at least two guide rods 482 to keep the moving path of the second rack 48 stable, and the outer surface of the second rack 48 is flush with the outer surface of the outer shell 45. The guide rod 482 and the guide sleeve 472 are located inside the outer shell 45, thereby ensuring that the outer shell 45 can move smoothly when it fits the support plate 171.

[0062] In order to solve the problem of how to make the inner push rod 46 automatically return to the inside of the support rod 43 after the placement seat 4 is reset, the following features are specifically set:

[0063] A counterweight block 463 is fixedly mounted on the bottom of the movable plate 461 , and a positioning plate 483 is provided at the bottom of the second rack 48 and extends horizontally to the bottom of the first rack 462 .

[0064] The movable plate 461 in this embodiment is provided with a counterweight block 463 at the bottom, and the counterweight block 463 has a certain weight. Therefore, when the third linear drive 14 drives the placement seat 4 to move toward one side of the winding machine 2, after the placement seat 4 automatically restores the vertical state, the counterweight block 463 can drive the movable plate 461 to move downward under the action of gravity, so that the inner push rod 46 enters the interior of the support rod 43, which is convenient for the subsequent loading of the inductor. At the same time, the downward movement of the first rack 462 drives the gear 471 to rotate to make the second rack 48 move up and reset. When the positioning plate 483 at the bottom of the second rack 48 is in contact with the bottom end of the first rack 462, the first rack 462 and the second rack 48 stop moving, keeping the inner push rod 46 in the position of the support rod 43, and also accurately positioning the position of the extension plate 481, to ensure that in the subsequent processing process, when the third linear drive 14 drives the placement seat 4 to move to a certain position, the inner push rod 46 can push out the inductor.

[0065] Working principle: the winding machine 2 winds the inductor and cuts the wire after winding. The cut wire is lifted up to the two sides of the pins of the inductor. The third linear drive 14 drives the placement seat 4 to move toward the winding machine 2. The articulated seat 441 moves the shell 45 close to the winding machine 2 and fits the adjustment block 16 set on the base 1 during the process of following the working end of the third linear drive 14 to move toward the winding machine 2. The adjustment block 16 lifts the bottom end of the shell 45 and gradually rotates it around the axis of the shaft 44 to a horizontal state, so that the positioning slot 41 of the placement seat 4 opens toward the winding machine 2. Then the inductor that has been wound can be The mechanical arm of the vacuum suction cup is adsorbed and moved to the placement seat 4. The inductors are inserted one by one into the contoured holes 42 set in the positioning groove 41 on the placement seat 4 for placement. The placement seat 4 drives the inductor to move to the bottom of the spot welding machine 3. The bottom end of the shell 45 of the placement seat 4 fits the support block 15 to keep the placement seat 4 vertical. The welding window 111 on the lifting frame 11 can be moved down and inserted into the positioning groove 41 of the placement seat 4 for positioning. The downward pressing rod 113 set on the horizontal frame rod 112 located in the middle of the welding window 111 moves the inductor in the contoured hole 42 downward when entering the positioning groove 41, so that the inductor enters the contoured hole 42 As the inductor moves downward in the profiling hole 42, the wire is limited by the wire groove 421 on the side of the profiling hole 42, and is automatically squeezed to a vertical state and fits on both sides of the inductor pin. Then the spot welder 3 can move along the lifting frame 11, and the working end of the spot welder 3 spot welds the pin and wire of the inductor in the positioning groove 41 through the welding window 111 to complete the processing of the inductor. After the spot welder 3 completes the welding of all the inductors in the placement seat 4, the third linear drive 14 drives the placement seat 4 to move toward the hanger 17, so that the side of the housing 45 away from the winding machine 2 fits the hanger 17, and the housing 45 is wound around the axis The axis of the rod 44 rotates to a horizontal state, and the positioning groove 41 of the placement seat 4 is horizontally oriented above the collection box 18. As the third linear drive 14 drives the placement seat 4 to move, the extension plate 481 in the vertical state moves to the side of the fitting rack 17. In the subsequent process in which the third linear drive 14 continues to drive the placement seat 4 to move, the position of the extension plate 481 remains unchanged, thereby causing the gear 471 to rotate, thereby driving the first rack 462 to move in the moving direction of the placement seat 4, and driving the inner push rod 46 to push the inductor in the contoured hole 42 outward, so that it falls into the collection box 18 on the side of the rack 17 for collection.
