Description

Technical Field

[0001] The present invention relates to the field of inductor preparation, and more specifically, to a material strip slicing and cutting device for inductor production. Background Art

[0002] In the production process of the coil core of the integrally formed inductor, the cutting equipment is first required to process the rolled material strip, which is cut into sheets of suitable length and arranged on a tray, and then the tray is transported to the next processing link; then the multiple sheets are simultaneously moved to the coil welding part by a grabbing and transferring device, and then the sheet and the coil are welded by laser welding to form a coil core of sheet specifications, completing the processing;

[0003] Its overall automation level is relatively high, and it can achieve highly efficient processing and production; however, there is correspondingly room for improvement, especially in the processing process of the cutting equipment. In order to facilitate the insertion of the material strip, one end of the material trough of the material tray is open, even in the subsequent transfer process. The internal material strips are in a loose state, and may be offset during the transfer to the next link, which is not convenient for subsequent alignment and affects the processing accuracy; there are even cases where the ends of some material strips extend out of the trough, requiring manual intervention and adjustment, affecting the overall processing and production, so this needs to be improved.

[0037] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0038] As Figures 1 to 6 shown, a material strip slicing and cutting device for inductor production disclosed in a specific embodiment of the present invention includes a straightening device 100, a blanking device 200, and an output device 300; the straightening device is used for straightening the fed material strip and conveying it to the blanking device; the blanking device is used for stamping and cutting the material strip into material pieces; the output device 300 includes a material carrier tray 500 and a transfer structure 400 for driving the material carrier tray to move; a plurality of material grooves 620 are provided on the material carrier tray 500 at uniform intervals along the moving direction, the material grooves extend along the feeding direction of the straightening device, and one end of the material groove close to the blanking device is open;

[0039] A clamping structure 700 is installed on the material-carrying tray 500. When in the clamped state, it is used to block the open end of the material groove and press the end of the material piece in the material groove; the material-carrying tray travels under the punching device with the center distance between two adjacent material grooves as the step stroke, and the punched material pieces are placed in the material grooves; after the material-carrying tray leaves the punching area, it changes from the unlocked state to the clamped state.

[0040] The above-mentioned material tape slicing and cutting equipment for inductor production can achieve continuous actions of straightening, cutting and slicing, and arranging and conveying through the cooperation of the straightening device, punching device, and output device. It has a high degree of automation and can improve the overall working efficiency.

[0041] A clamping structure is installed on the material-carrying tray. When the clamping structure is in the unlocked state, the end of the material groove remains open for the insertion of the material tape; when the clamping structure is in the clamped state, it blocks the open end of the material groove and presses the end of the material piece in the material groove; the material-carrying tray adjusts and changes the state of the clamping structure according to the change of position, which can not only meet the placement of the material strip during punching, cutting and slitting, but also effectively prevent the material strip from loosening or shifting during the transfer of the material-carrying tray, so as to maintain accurate alignment and facilitate subsequent processing and production.

[0042] Among them, the transfer structure includes but is not limited to a linear slide or a lead screw mechanism. The material-carrying tray can be installed on the sliding seat and is driven by the transfer structure to move back and forth linearly; the straightening device includes a pair of rollers driven by a motor and multiple groups of guide rollers distributed in a staggered manner up and down, which are used for tortuously bending and conveying the incoming material tape and straightly conveying it to the punching device at the end, so that the material tape is output straightly; the punching device includes a punching die and a cylinder for driving the punching die to lift and lower. The punching die is provided with a cutting knife and a pressing component. During punching and cutting, the material tape is first pressed, and then the cutting knife cuts the material tape to achieve slicing. It should be noted that the above-mentioned transfer structure, straightening device, and punching device are all relatively conventional structural instruments and are relatively mature, so they will not be elaborated here.

[0043] Further, as Figures 4 to 6 shown, the material-carrying tray 500 includes a tray 600 and a clamping structure 700; a downwardly concave collecting groove 610 is provided on the top surface of the tray 600 near the punching device. The open ends of the material grooves 620 all converge at the collecting groove 610, and a plurality of card slots 630 corresponding to the material grooves 620 are provided at the collecting groove 610; the material grooves and the collecting groove are sunken parts relative to the top surface of the tray. Especially for the material groove part, it can limit the material strip on both sides to prevent offset in the width direction; the design of the collecting groove and the card slots can provide an installation area position for the clamping structure and also provide an operating space for the punching device to perform punching and cutting.

[0044] The clamping structure 700 includes a plurality of stoppers 710, which are correspondingly arranged in the card slots 630; the clamping structure is adjusted to rotate all the stoppers synchronously. When the stoppers rotate and swing to the upright position, they protrude from the bottom of the material discharging groove and are in the clamping state; when the stoppers rotate and swing to the horizontal position, they are received inside the card slots and are in the unlocked state; the stoppers change their positions by rotation, which can minimize the impact on the strip during the adjustment process, especially when the strip is removed from the material loading tray.

[0045] Furthermore, as Figures 4 to 8 shown, the clamping structure 700 includes stoppers 710, a rotating shaft 720, and a pushing frame 730; the rotating shaft 720 is rotatably penetrated through the support plate 600 and runs through all the card slots 630. The stoppers 710 are clamped and installed on the rotating shaft 720 and rotate with the shaft; two gears 740 are installed at both ends of the rotating shaft 720, and corresponding guide grooves 640 are provided on both sides of the bottom surface of the support plate 600. The gears 740 are arranged in the guide grooves 640; the guide grooves extend along the length direction of the material groove and are open at one end close to the blanking device; racks 731 are provided at both ends of the pushing frame 730. The racks 731 are inserted into the guide grooves 640 and slide along the guide grooves, and the racks 731 are meshed with the gears 740 for transmission. Moving the pushing frame can drive the rotating shaft to rotate, thereby changing the placement state of the stoppers; through the transmission of the gear and the rack, the horizontal movement of the pushing frame is converted into the rotation movement of the stoppers. By adjusting the pushing frame, the adjustment action can be realized, which is convenient for operation and also facilitates the design of other subsequent supporting structural components.

[0046] Furthermore, as Figure 10 shown, a support block 650 is fixedly provided inside the guide groove 640, and there is a spacing between the support block and the end of the guide groove. A guide hole 651 penetrating both ends is provided on the support block 650; as Figures 5 to 7 shown, the pushing frame 730 includes a push rod 732, racks 731 fixedly provided at both ends of the push rod 732, a guide rod 733 fixedly provided at the end of the rack 731 away from the push rod 732. The guide rod 733 movably penetrates through the guide hole 651, and a snap ring for preventing detachment is provided at the end of the guide rod; a spring 750 is sleeved on the guide rod 733, and the spring 750 is clamped between the support block 650 and the end of the rack 731 to provide an outward pushing and resetting elastic force for the pushing frame; when the pushing frame is only affected by the elastic force of the spring, the pushing frame is pushed outwards and unfolded, and the snap ring abuts against the support block. At this time, the stoppers are in the upright placement position; by setting the spring as the power component for the outward pushing and resetting of the pushing frame, the overall assembly is convenient; at the same time, it also means that only an external force needs to be applied to the pushing frame to realize the adjustment action. After the force is removed, the pushing frame can be pushed outwards and reset by the elastic force of the spring, and the stoppers naturally swing and adjust to the blocking state, which is also convenient for the design and layout of other corresponding structural components.

[0047] Furthermore, as Figure 5As shown, the middle part of the wall surface of the push rod 732 away from the guide rod bulges outwards, forming two first inclined surfaces on both sides, and a rolling member 734 is installed at the center of the bulge of the push rod; as Figure 1 , Figure 13 As shown, a supporting seat 800 is provided below the cutting knife of the blanking device 200. A stop bar 810 is provided on the supporting seat 800. The stop bar extends along the moving direction of the material loading tray. The wall surface of the stop bar 810 away from the straightening device includes a connected guiding surface 811 and a limiting surface 812; the guiding surface is inclined to provide buffer guidance for the telescopic movement of the pushing frame; the limiting surface is used to maintain the pushing frame in a compressed state and keep the port of the material trough open; the provided stop bar serves as a structural component for pushing the pushing frame. Utilizing the power of the transfer structure to drive the movement of the material loading tray, when the pushing frame enters the pushing range of the stop bar, the clamping structure can be changed to the released state, opening the port of the material trough to facilitate the entry of the material strip; moreover, the middle part of the push rod bulges, and a rolling member is installed at the bulge, which can effectively reduce the contact area between the entire pushing frame and the stop bar and reduce the frictional resistance; it can also achieve the effect of gradually squeezing the pushing frame when passing through the guiding surface, realizing the function of buffer guidance; it should be noted that the rolling member includes but is not limited to a roller and a bull's eye bearing. A hole is provided at the bulge of the push rod, and the rolling member is installed in the hole so that the rolling part protrudes outside. The main purpose is to make contact and cooperation between the rolling part and the stop bar to achieve the pushing action.

[0048] Furthermore, the top surface of the supporting seat 800 is flush with the bottom surface of the support plate 600, and the bottom surface of the support plate is in sliding contact with the top surface of the supporting seat; when the support plate moves to the top surface of the supporting seat, the blanking device uses the bottom of the collecting trough as the supporting part for punching the material strip; there is no need to additionally set up a transfer structure, and the cut and separated material strips directly fall into the material trough, making the overall structure more compact and simplifying the operating actions.

[0049] Furthermore, as Figure 9 shown, a convex block 660 is fixedly provided at the top of one end of the card slot 630 close to the center of the support plate. The top surface of the convex block 660 extends to be flush with the bottom of the collecting trough 610. The end of the convex block 660 away from the center of the support plate extends beyond the port of the material trough 620; the cutting knife of the blanking device corresponds to the position of the notch of the material trough, and the convex block is used as the supporting part for punching the material strip, ensuring that the supporting part for cutting maintains a complete and flat condition, avoiding the part of the card slot, and ensuring effective cutting and separation of the material strip.

[0050] Furthermore, as Figure 7As shown, the bottom of the protrusion 660 near the card slot is provided with an arc-shaped concave surface 661, and the arc center axis of the concave surface coincides with the center axis of the rotating shaft; the bottom of the stopper 710 is an arc block structure, and is adapted to the shape of the concave surface. The bottom outer wall of the stopper slides against the concave surface, so that part of the stopper is close to the concave surface, and can also provide a local support effect for the protrusion, dispersing the force of the protrusion; on the other hand, the two structures can be made more compact, which is convenient for the layout of other structural components; and, as Figure 12 As shown, a bayonet 711 is provided on the side wall of the stopper 710 corresponding to the protrusion, and the shape of the bayonet 711 is adapted to the shape of the protrusion 660; when the stopper is rotated to an upright position, a gap 900 adapted to the thickness of the sheet is formed between the bayonet and the top surface of the protrusion; using the protruding part of the protrusion as a limitation, the stopper is swung in the clamping direction, providing an inward pushing force to the sheet, which can push the sheet to the end of the material slot and form a clamping effect at the end position of the sheet; when the stopper is swung in the unlocking direction, its bayonet part passes over the sheet, which naturally will not affect the placement of the sheet and will not cause its position to shift.

[0051] Furthermore, if Figure 13 As shown, the rotating shaft 720 includes a first shaft rod 721, and the two ends of the first shaft rod 721 are respectively fixed with a second shaft rod 722 and a third shaft rod 723, the end of the second shaft rod 722 is fixed with a first cylindrical block 724, and the end of the third shaft rod 723 is fixed with a second cylindrical block 725; a plurality of evenly spaced blocks 726 are fixed on the first shaft rod 721; the second shaft rod, the third shaft rod, and the blocks are all prismatic column structures, and corresponding prismatic holes are opened on the gears and blocks to ensure that the corresponding gears and blocks can rotate synchronously with the rotating shaft after being installed in place;

[0052] The second shaft and the block have the same cross-sectional structure, and the minimum outer diameter is greater than the diameter of the first shaft; the maximum outer diameter of the third shaft is smaller than the diameter of the first shaft; the diameter of the first cylindrical block is greater than the maximum outer diameter of the second shaft, and the diameter of the second cylindrical block is smaller than the minimum outer diameter of the third shaft; Figure 10 As shown, two opposite side walls of the support plate 600 are respectively provided with a first circular hole 671 and a second circular hole 672 which are communicated with the adjacent guide grooves, the aperture of the first circular hole 671 is adapted to the shape of the first cylindrical block 724, and the aperture of the second circular hole 672 is adapted to the shape of the second cylindrical block 725; a third circular hole 673 which passes through all the clamping grooves 630 is provided between the two guide grooves 640, and the aperture of the third circular hole 673 is larger than the maximum outer diameter of the clamping block 726; this ensures that the rotating shaft can be smoothly inserted and rotatably installed on the baffle;

[0053] The stoppers are correspondingly clamped and installed on the clamping blocks, and at least one stopper is fixed on the rotating shaft through a dowel pin. Two gears are respectively fitted and installed on the second shaft rod and the third shaft rod. When the stopper is fixed on the rotating shaft, the axial direction of the stopper is limited by both sides of the card slot, which means that the rotating shaft cannot be withdrawn from the hole position, and thus the required rotational fit is naturally maintained.

[0054] Among them, the bottom of the guide groove is open, and a support plate is installed at the open place. Through a detachable structure, it is convenient for the assembly of internal gears, rotating shafts, racks, guide rods, and springs, realizing the overall construction.

[0055] More specifically, the specific cutting and slicing actions include the following steps:

[0056] S1, The external tape reel feeds the tape and transmits it to the straightening device.

[0057] S2, The straightening device straightens and conveys the tape and extends it outwards by a preset length.

[0058] S3, The transfer structure drives the material-carrying tray to move back to a preset position. The pushing frame abuts against the limiting surface, and the stopper is in the unlocked state. At this time, the position of the first material slot corresponds to the position of the tape.

[0059] S4, The straightening device starts and drives the tape to extend towards the material slot by a preset length, and the tape enters the material slot.

[0060] S5, The punching device starts to cut the tape, and the separated tape pieces stay at this material slot.

[0061] S6, The transfer structure continues to move back a preset distance, and the tape corresponds to the next material slot.

[0062] S7, Repeat the steps of S4 - S6 until all the material slots are filled with tape pieces.

[0063] S8, The transfer structure drives the material-carrying tray to move forward towards the next processing equipment. When the rolling member disengages from the limiting surface, the pushing frame gradually extends outwards, driving the stopper to rotate and swing upwards from the bottom, pushing the tape piece towards the end of the material slot. When the rolling member disengages from the retaining bar, the stopper forms a clamping and pressing action on the tape piece and maintains it during the conveying process.

[0064] When it moves to the next processing equipment, an external structure applies a force to push and press the pushing frame, and then the locking action is released, so that the tape piece is clamped and pressed during the entire transfer process, effectively preventing the tape piece from loosening or shifting, and avoiding affecting the subsequent alignment and processing accuracy.

[0065] The present invention is described by way of preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention.
