[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-13 A TLVR inductor coil fabrication apparatus, comprising: Paint stripping mechanism 1 strips the paint from metal segment 14; The folding gate mechanism 2 is used to bend the metal segment into a gate shape to form a gate coil 15. The bending direction is configured such that the outer side of the gate coil is the outer side with the paint already peeled off. Tinning mechanism 3 tins the gate coil, so that the outer surface of the gate coil is tinned; The lead-cutting mechanism 4 cuts off the excess lead length of the gate coil after tinning; The folding mechanism 5 folds the two legs of the cut-leg gate coil inward to form a mouth shape, thus obtaining the mouth-shaped coil.

[0021] By setting an additional lead-cutting mechanism, there is no need to worry about the solder covering the bottom surface of the gate coil during soldering. Thus, after the gate coil with cut leads is bent into a chamfer shape, there is no solder on the lead surfaces corresponding to the beginning and end of the chamfer coil.

[0022] In some embodiments, the fabrication apparatus further includes a wire feeding mechanism 6 and a wire cutting mechanism 7. The wire feeding mechanism is used to feed metal wire (such as copper wire). The wire cutting mechanism is used to cut the metal wire into metal segments, the length of which is longer than the actual length of the die coil, to allow for "excess leg length".

[0023] In some embodiments, the preparation apparatus further includes a first positioning mold 9, which is used to position the metal segment.

[0024] For example, positioning the metal segment for the paint stripping mechanism enables the mechanism to better strip the paint from the metal segment.

[0025] For example, positioning metal segments can be added to folding gate mechanisms to enable them to bend the metal segments more effectively.

[0026] In some embodiments, the wire feeding mechanism includes a wire reel 601 driven by a motor, which unwinds the wound metal wire.

[0027] Preferably, the wire feeding mechanism further includes a wire pressing seat 602, which is provided with a straight through hole. The metal wire passes through the straight through hole, so that the bending state of the metal wire caused by winding is shaped into a straight state.

[0028] In some embodiments, the wire cutting mechanism 7 includes a wire segment punching assembly 701 and a fixed-length conveying assembly 702.

[0029] The metal wire unwound from the spool is conveyed to the segment punching assembly at a fixed length by the directional feeding assembly, and the segment punching assembly cuts the metal wire into metal segments of corresponding lengths.

[0030] In some embodiments, the fixed-length conveying assembly 702 is located between the line segment punching assembly 701 and the wire feeding mechanism 6.

[0031] In some embodiments, the fixed-length conveying assembly 702 includes a first clamping drive 7021, a first clamping frame 7022, a second clamping drive 7023, a second clamping frame 7024, and a fixed-length conveying drive 7025.

[0032] Both the first and second pressing drive members have pressing heads, and the pressing heads of the first and second pressing drive members are spaced apart along the length of the metal wire.

[0033] The clamping head of the first clamping drive unit cooperates with the first clamping frame to clamp the metal wire; the fixed-length conveying drive unit is used to drive the first clamping drive unit and the first clamping frame to move along the length direction of the metal wire, and the first clamping drive unit and the first clamping frame are arranged on the conveying end of the fixed-length conveying drive unit; the clamping head of the second clamping drive unit cooperates with the second clamping frame to clamp the metal wire, and the second clamping frame is close to the wire segment punching assembly.

[0034] The first clamping drive 7021, the second clamping drive 7023, and the fixed-length conveying drive 7025 are all, for example, cylinders. The clamping head and the conveying end are mounted on the corresponding piston rods.

[0035] The metal wire unwound from the spool is first pressed onto the first clamping frame 7022 by the clamping head of the first clamping drive 7021. The fixed-length conveying drive 7025 drives the first clamping drive 7021 and the first clamping frame 7022 toward the clamping head of the second clamping drive 7023, that is, toward the wire segment punching assembly 701, so as to convey the metal wire to the corresponding length. Next, the clamping head of the second clamping drive 7023 clamps the conveyed metal wire onto the second clamping frame 7024 to hold the metal wire. Subsequently, the clamping head of the first clamping drive 7021 cancels the clamping of the metal wire and is driven back by the fixed-length conveying drive 7025 to continue clamping and conveying the next length; after the clamping head of the first clamping drive returns to clamp the metal wire for the next time, the clamping head of the second clamping drive can correspondingly cancel the clamping of the metal wire. Furthermore, the segment punching assembly can punch and cut the conveyed metal wire to obtain metal segments.

[0036] In some embodiments, the line segment punching assembly 701 includes a line segment punching bracket and a line segment punching cylinder 7011 disposed on the line segment punching bracket. The piston rod of the line segment punching cylinder 7011 extends downward and is connected to a line segment cutter 7012. A line segment punching die 7013 located below the line segment cutter is disposed on the line segment punching bracket.

[0037] The fixed-length conveying drive conveys the metal wire along its length to the clamping head of the second clamping drive, and continues to convey it between the wire segment cutter and the wire segment punching die.

[0038] In some embodiments, the first positioning mold 9 includes a first mold base 901, on which a first upper and lower guide rail is provided, and on which a first opening and closing guide post 902 is provided, the upper end of the first opening and closing guide post 902 extends upward through the first upper and lower guide rail and is connected to a first opening and closing pressure block 903, and the first opening and closing pressure block 903 moves downward to press the metal segment onto the lower first mold base.

[0039] The lower end of the first opening and closing guide post 902 extends downward through the first upper and lower guide rails and is connected to the first opening and closing limiting block 904. The lower end of the first opening and closing guide post is fitted with a first opening and closing compression spring 905, which is located between the first opening and closing limiting block 904 and the first mold base 901.

[0040] Preferably, the first positioning mold further includes a first opening and closing drive component 906. The drive end of the first opening and closing drive component is located below the first opening and closing guide post. The drive end of the first opening and closing drive component pushes the first opening and closing guide post upward to separate the first opening and closing pressure block from the first mold base, thereby compressing the first opening and closing clamping spring. The driving end of the first opening and closing drive member moves downward away from the first opening and closing guide post. The first opening and closing guide post moves downward under the action of the first opening and closing clamping spring, so that the first opening and closing pressure block presses downward onto the first mold base. For example, the first opening and closing pressure block is configured to press the middle part of the metal segment onto the first mold base.

[0041] The first opening and closing drive component is, for example, a cylinder.

[0042] In some embodiments, the wire cutting mechanism 7 further includes a metal segment feeding assembly 703, which is used to transport the cut metal segments to the first positioning mold.

[0043] In some embodiments, the metal segment feeding assembly 703 includes a metal segment conveying cylinder 7031 and a metal segment pneumatic gripper 7032. The metal segment pneumatic gripper 7032 clamps the conveyed metal wire, and after the wire segment punching assembly punches it, a metal segment clamped by the metal segment pneumatic gripper is obtained.

[0044] The metal segment conveying cylinder drives the pneumatic gripper of the metal segment to move the metal segment to the first positioning mold.

[0045] In some embodiments, the metal segment pneumatic gripper clamps the metal segment at, for example, both ends of the metal segment. Thus, when the metal segment changes between the metal segment pneumatic gripper and the first positioning mold, the first opening and closing pressure block and the first mold base can directly press the middle of the metal segment without needing to readjust the clamping position.

[0046] In some embodiments, the paint stripping mechanism 1 includes a laser paint stripping machine that lasers the metal segment on the first positioning mold from top to bottom to remove the paint from the metal segment.

[0047] In some embodiments, the folding door mechanism 2 includes a first stamping bracket 201 and a first stamping cylinder 202 disposed on the first stamping bracket. The piston rod of the first stamping cylinder 202 extends downward and is connected to two foot-pressing elbows 203.

[0048] The first stamping cylinder drives the foot bending head downward to bend the metal segment that is pressed together by the first opening and closing pressure block and the first mold base, forming a gate-shaped coil 15.

[0049] In some embodiments, the preparation apparatus further includes a first indexing plate 10, and a first mold base 901 is disposed on the first indexing plate 10.

[0050] Preferably, at least two front-end indexing positions can be formed by the first indexing plate, the first front-end indexing position corresponds to the metal segment feeding assembly or the paint stripping mechanism, and the second front-end indexing position corresponds to the folding door mechanism.

[0051] Correspondingly, two second mold bases and two first opening and closing drive components are provided, with the two first opening and closing drive components respectively located near the two front indexing positions.

[0052] For example, the first opening and closing drive member is located near the first front indexing position to drive the first opening and closing guide rod on the first mold base located at the first front indexing position; the second opening and closing drive member is located near the second front indexing position to drive the first opening and closing guide rod on the first mold base located at the second front indexing position.

[0053] The first mold base and its first opening and closing pressure block can receive the metal segment conveyed by the metal segment feeding assembly at the first front end indexing position, and hold the metal segment so that the metal segment can be laser stripped by the laser paint stripping machine above.

[0054] The first indexing plate can rotate and move the first mold base located at the second front indexing position to the first front indexing position, and rotate and move the first mold base located at the first front indexing position to the second front indexing position.

[0055] The folding gate mechanism bends the metal segment on the first mold base at the area corresponding to the second front indexing position, forming a multi-station operation, which helps to improve the efficiency of paint stripping and folding gate processes.

[0056] In some embodiments, the tinning mechanism 3 includes 301 gate-type coil discharge linear vibration guide rail; The portal coil feeding mechanism 302 moves the portal coil on the first positioning mold to the portal coil discharge linear vibration guide rail; The layout fixture 303 is provided with multiple gate-shaped coil positioning molds 3031. For example, the multiple gate-shaped coil positioning molds are spaced apart along a straight line, or spaced apart along the same direction as the straight output direction of the gate-shaped coil discharge straight vibration guide rail. The portal coil feeding mechanism 304 picks up the portal coils arranged on the portal coil discharge linear vibration guide rail and places them on the portal coil positioning mold; Tin furnace 305; The gate-type coil moving tinning mechanism 306 moves the gate-type coil on the layout fixture to the tin pot to tin the gate-type coil.

[0057] In some embodiments, the gate coil feeding mechanism 302 includes a gate coil ejection cylinder 3021, the piston rod of which extends laterally and is connected to a gate coil pusher head 3022.

[0058] The gantry coil ejection cylinder is positioned, for example, near the second front indexing position, and the gantry coil discharge linear vibration guide rail is positioned near the second front indexing position.

[0059] After the folding gate is completed, and after the first opening and closing drive unit lifts the first opening and closing guide post on the first mold base located at the second front indexing position, the gate coil ejection cylinder laterally drives the gate coil pusher head to push the gate coil from the first mold base to the gate coil discharge linear vibration guide rail. That is, before ejection, the gate coil on the first mold base is located between the gate coil pusher head and the inlet of the gate coil discharge linear vibration guide rail.

[0060] In some embodiments, the gate-type coil feeding mechanism 304 includes a first electrically controlled moving component 3041 and a first gate-type coil gripping component 3042, wherein the first gate-type coil gripping component 3052 is disposed on the moving end of the first electrically controlled moving component 3041.

[0061] In some embodiments, the first gate coil gripping component 3042 includes a first vacuum nozzle disposed on the moving end of the first electrically controlled moving component.
