Detailed implementation manners

[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. Figure 9As shown in the figure, subsequently, the spot welder 3 can move along the lifting frame 11. 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, completing the processing of the inductor. In this embodiment, the placement seat 4, through its cooperation with the lifting frame 11, automatically positions the two ends of the wire when the inductor is fully inserted into the profiling hole 42, causing the wire to automatically fit against the pins on both sides of the inductor before welding, and the welding position is within the welding window 111, facilitating direct spot welding by the spot welder 3.

[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] At both ends of the lifting frame 11, the base 1 is fixedly installed with a first linear actuator 12. The lifting frame 11 is installed on the working end of the first linear actuator 12, and the working end of the first linear actuator 12 is arranged to move in the vertical direction.

[0042] The first linear actuator 12 in this embodiment can be a cylinder or an electric push rod. The first linear actuator 12 is installed at both ends of the lifting frame 11 to drive the lifting frame 11 to lift and lower in the vertical direction, enabling the welding window 111 to 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 welder 3 to move along the length direction of the lifting frame 11 to perform precise spot welding on all inductors, the following features are specifically set:

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

[0045] In this embodiment, the lifting frame 11 is provided with a second linear actuator 13 for driving the spot welder 3 to move along the length direction of the lifting frame 11. The second linear actuator 13 can be a lead screw slide table, etc. The spot welder 3 moves on the working end of the second linear actuator 13, and can sequentially weld the inductors in the welding windows 111 evenly distributed along the length direction of the lifting frame 11. Moreover, the second linear actuator 13 installed on the lifting frame 11 can achieve the synchronous lifting and lowering of the spot welder 3 and the lifting frame 11, ensuring the uniformity of the welding height of the working end of the spot welder 3.

[0046] In order to achieve the movement of the support rod 43 within the profiling hole 42 so that the inductor can maintain its relative position when initially entering the profiling hole 42 and can continue to move downward under the pressing of the pressing rod 113, the following features are specifically set:

[0047] A sleeve 431 with an opening facing 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 moves the support rod 43 upward; the width of the sleeve 431 is greater than the diameter of the support rod 43, and the elastic force of the spring 433 causes the sleeve 431 to fit against the bottom of the profiling hole 42.

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

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

[0050] Shaft rods 44 are provided at the top of both ends of the placement seat 4. The shaft rods 44 extend along the length direction of the placement seat 4. Hinge seats 441 are rotatably installed on the shaft rods 44; a third linear driver 14 is provided on the base 1. The working end of the third linear driver 14 moves in a horizontal direction perpendicular to the length direction of the placement seat 4. The hinge seat 441 is fixedly installed on the working end of the third linear driver 14. The winding machine 2 is fixedly installed at one end of the third linear driver 14. The spot welder 3 is arranged on the moving path of the third linear driver 14; an outer shell 45 is provided outside the placement seat 4. The bottom of the outer shell 45 is suspended. A support block 15 is provided on the base 1 below the spot welder 3. When the bottom of the outer shell 45 fits against the bottom of the support block 15, the placement seat 4 remains vertical; an adjusting block 16 is provided on the base 1 on the side of the support block 15 facing the winding machine 2. When the side of the outer shell 45 fits against the top of the adjusting block 16, the positioning groove 41 is horizontally oriented towards the winding machine 2.

[0051] An arc surface extending obliquely downward is provided on the side of the adjusting block 16 facing the support block 15.

[0052] In this embodiment, the placement seat 4 is installed on the working end of the third linear driver 14 provided on the base 1. The third linear driver 14 can be a lead screw slider or the like. The third linear driver 14 can drive the placement seat 4 to move. The placement seat 4 is rotatably installed on the hinge seat 441 through a shaft rod 44. During the process of the hinge seat 441 following the working end of the third linear driver 14 and moving towards the winding machine 2, the side of the housing 45 close to the winding machine 2 fits against the adjusting block 16 provided on the base 1. The adjusting block 16 lifts the bottom end of the housing 45 and gradually rotates around the axis of the shaft rod 44 to a horizontal state, so that the opening of the positioning groove 41 of the placement seat 4 faces the winding machine 2, facilitating the insertion of the inductor into the profiling hole 42. Subsequently, the third linear driver 14 drives the hinge seat 441 to move towards the spot welder 3. After the placement seat 4 separates from the adjusting block 16, it returns to the vertical state and the bottom is suspended. When the placement seat 4 is translated below the spot welder 3, the support block 15 on the base 1 fits against the bottom of the housing 45. Therefore, the housing 45 cannot rotate around the axis of the shaft rod 44, thus maintaining the vertical state, facilitating the lowering of the lifting frame 11 so that the lifting frame 11 is inserted into the positioning groove 41.

[0053] In order to facilitate the separation of the inductor inserted in the profiling hole 42 from the profiling hole 42 for blanking, the following features are specifically set:

[0054] At one end of the base 1 away from the adjusting block 16, a vertical hanging rack 17 is provided. At the top of the hanging rack 17, a horizontal support plate 171 is provided. When the side of the housing 45 fits against the support plate 171, the positioning groove 41 of the placement seat 4 is horizontally oriented towards the end away from the winding machine 2. At one end of the base 1 away from the adjusting block 16 and away from the hanging rack 17, a collection box 18 with an upward opening is provided; an inner through hole 434 penetrating the support rod 43 is provided inside the support rod 43 of the placement seat 4. An inner ejector rod 46 is coaxially arranged inside the inner through hole 434. The inner ejector rod 46 moves along the axis of the support rod 43 to eject the inductor in the profiling hole 42 out of the placement seat 4 and into the collection box 18.

[0055] After the spot welder 3 in this embodiment completes the welding of all the inductors in the placement seat 4, the third linear driver 14 drives the placement seat 4 to move towards the hanging rack 17, so that the side of the housing 45 away from the winding machine 2 fits against the hanging rack 17, and the housing 45 rotates around the axis of the shaft rod 44 to a horizontal state. The positioning groove 41 of the placement seat 4 is horizontally oriented above the collection box 18. An inner through hole 434 is provided at the axis of the support rod 43 in this embodiment. The inner ejector rod 46 inserted inside the inner through hole 434 can move along the axis direction of the support rod 43 at this time to eject the inductor in the profiling hole 42, so that it falls into the collection box 18 on one side of the hanging rack 17 for collection, and the blanking can be automatically completed.

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

[0057] All the inner ejector rods 46 are inserted into the guiding holes provided at the bottom of the placing seat 4, and the bottom ends of all the inner ejector rods 46 are fixedly connected to the moving plate 461; on one side of the moving plate 461 away from the winding machine 2, a first rack 462 is provided, and the teeth on the first rack 462 are evenly distributed along the axial direction of the support rod 43. On the side of the placing seat 4 away from the winding machine 2, a mounting frame 47 is fixedly installed, and a gear 471 is rotatably installed on the mounting frame 47. The axis of the gear 471 is arranged along the length direction of the placing seat 4, and the gear 471 is meshed and connected with the first rack 462; on the side of the placing seat 4 away from the winding machine 2, a second rack 48 is slidably installed, the second rack 48 is meshed and connected with the gear 471, and the surface of the second rack 48 away from the winding machine 2 is flush with the side surface of the housing 45. On the side of the second rack 48 away from the gear 471, an extension plate 481 perpendicular to the second rack 48 is provided.

[0058] In this embodiment, the inner ejector rod 46 in each support rod 43 passes through the guiding hole on the placing seat 4 and is connected to the moving plate 461 at the bottom of the placing seat 4. Both the first rack 462 on the moving plate 461 and the second rack 48 slidably installed outside the placing seat 4 are meshed and connected with the gear 471. Therefore, when the second rack 48 moves, it can drive the moving plate 461 to move in the axial direction of the support rod 43, realizing the movement of the inner ejector rod 46. When the housing 45 is attached to the hanging rack 17, the housing 45 rotates, causing the horizontal extension plate 481 provided at the bottom of the second rack 48 on the side of the housing 45 facing the hanging rack 17 to flip to the vertical state. As the third linear driver 14 drives the placing seat 4 to move, the vertical extension plate 481 moves to the side attached to the hanging rack 17. During the subsequent process of the third linear driver 14 continuing to drive the placing seat 4 to move, the position of the extension plate 481 remains unchanged, thereby causing the gear 471 to rotate, and then driving the first rack 462 to move in the moving direction of the placing seat 4, driving the inner ejector rod 46 to push the inductor in the profiling hole 42 outwards, realizing the automatic blanking of the inductor.

[0059] In order to ensure the stable sliding of the second rack 48 outside the placing seat 4, the following features are specifically set:

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

[0061] In this embodiment, the second rack 48 keeps the moving path stable by inserting at least two guiding rods 482 into the guiding sleeves 472 on the mounting frame 47, and the outer surface of the second rack 48 is flush with the outer surface of the housing 45. The guiding rods 482 and the guiding sleeves 472 are located inside the housing 45. Therefore, it can ensure the smooth movement when the housing 45 fits and moves along the support plate 171.

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

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

[0064] In this embodiment, a counterweight 463 is provided at the bottom of the moving plate 461. The counterweight 463 has a certain weight. Thus, during the process of the third linear driver 14 driving the placement seat 4 to move towards the winding machine 2, after the placement seat 4 automatically returns to the vertical state, the counterweight 463 can drive the moving plate 461 to move downward under the action of gravity, so that the inner ejector rod 46 enters the inside of the support rod 43, facilitating the subsequent feeding of the inductor. At the same time, the downward movement of the first rack 462 drives the gear 471 to rotate, causing the second rack 48 to move upward and reset. When the positioning plate 483 at the bottom of the second rack 48 fits against the bottom end of the first rack 462, the first rack 462 and the second rack 48 stop moving, maintaining the position of the inner ejector rod 46 in the support rod 43 and also accurately positioning the extension plate 481, ensuring that during the subsequent processing, when the third linear driver 14 drives the placement seat 4 to move to a certain position, the inner ejector 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.
