Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 The two legs of the uncut Z-shaped coil are referred to here as wings 100, and the protruding part in the middle of the uncut Z-shaped coil is referred to here as ridge 200 (or top).

[0022] The uncut-leg zigzag coil has an opening 300 corresponding to the ridge 200, which is located between the two wings. The uncut-leg zigzag coil also has a lateral channel 400 located between the ridge and the opening.

[0023] Please see Figure 1-10 In this embodiment, an inductor U-shaped coil lead-cutting device is used to cut the leads of an uncut U-shaped coil.

[0024] In some embodiments, the inductor U-shaped coil lead-cutting device includes a feeding station 2, a coil flipping and feeding mechanism 3, and a lead-cutting and feeding station 4.

[0025] The uncut Z-shaped coil is in an upright or nearly upright position at the feeding station 2, that is, the opening 300 of the uncut Z-shaped coil faces downward and the ridge 200 of the uncut Z-shaped coil faces upward.

[0026] The coil flipping and feeding mechanism 3 is used to receive the uncut lead Z-shaped coil from the feeding station 2, and flip and transport the uncut lead Z-shaped coil to the lead-cutting feeding station 4.

[0027] In some embodiments, the uncut-leg Z-shaped coils are vibrated and discharged via a corresponding vibratory feeder 21. During vibration discharge, multiple uncut-leg Z-shaped coils are sequentially conveyed onto a vertical vibratory track 22, with the openings of the coils facing downwards; that is, the coils are conveyed upright or nearly upright on the vertical vibratory track 22. The end of the vertical vibratory track 22 can directly discharge the aforementioned uncut-leg Z-shaped coils.

[0028] The position where the uncut Z-shaped coil is delivered at the end of the straight vibrating track 22 can be understood as the feeding station 2.

[0029] In some embodiments, the inductor U-shaped coil lead-cutting device includes a coil current-limiting mechanism 5, which limits / allows the uncut U-shaped coil to be delivered from the end of the linear vibrating track 22.

[0030] In some embodiments, the coil current limiting mechanism 5 includes an electrically controlled pressing assembly. The electrically controlled pressing assembly is configured to press or block the uncut-leg Z-shaped coil so that the uncut-leg Z-shaped coil cannot be delivered from the end of the linear vibration track 22; the electrically controlled pressing assembly is also configured to release the pressing or blocking of the uncut-leg Z-shaped coil so that the uncut-leg Z-shaped coil can be smoothly delivered from the end of the linear vibration track 22.

[0031] In some embodiments, the electrically controlled pressing assembly is configured to press the ridge 200 of an upright or nearly upright uncut-leg zigzag coil from top to bottom, so that the uncut-leg zigzag coil is pressed onto the straight vibrating track 22.

[0032] Preferably, the electrically controlled pressing assembly is configured to press the uncut Z-shaped coil onto the end of the straight vibrating track 22.

[0033] The electrically controlled pressing assembly can be a cylinder assembly, an electric push rod assembly, or other electrically controlled linear drive assembly. The driving end of the linear drive assembly is equipped with a coil pressing head. The linear drive assembly drives the coil pressing head to press down, thereby pressing the uncut Z-shaped coil onto the linear vibration track.

[0034] In some embodiments, the electrically controlled pressing assembly includes a mounting frame and a coil pressing cylinder.

[0035] The cylinder body of the coil clamping cylinder is mounted on a fixed frame. The piston rod of the coil clamping cylinder extends downward and is connected to the coil top pressure head, which is located above the linear vibration track.

[0036] The coil clamping cylinder can drive the coil pressing head downward to press the uncut-leg Z-shaped coil on the straight vibration track. The coil clamping cylinder can also drive the coil pressing head upward so that the uncut-leg Z-shaped coil can be smoothly delivered from the end of the straight vibration track.

[0037] In some embodiments, when the uncut-leg Z-shaped coil is fed out at the end of the straight vibrating track 22, the coil flipping and feeding mechanism 3 is used to receive the uncut-leg Z-shaped coil fed out from the end of the straight vibrating track 22, flip the uncut-leg Z-shaped coil and transport it to the cutting-leg feeding station 4.

[0038] In some embodiments, the uncut Z-shaped coil can also be delivered to the feeding station in other ways, such as by a robot gripping it to the feeding station or by a person placing it to the feeding station manually.

[0039] In some embodiments, the coil flipping and feeding mechanism 3 includes a flipping and displacement component 31 and a gripping component 32. The gripping component 32 grips the uncut-leg Z-shaped coil at the feeding station 2, and flips and moves the uncut-leg Z-shaped coil to the cutting-leg feeding station 4 through the flipping and displacement component 31.

[0040] In some embodiments, the gripping component 32 includes a pneumatic finger cylinder 321, with a fixed arm 322 connected to each of the two fingers of the pneumatic finger cylinder 321, and the fixed arm 322 having a support head 323.

[0041] After the support heads 323 of the two fixed arms of the two fingers approach or clamp each other, the two support heads can be inserted into the lateral channel 400 of the uncut-leg Z-shaped coil, or the uncut-leg Z-shaped coil can be moved to be inserted into the lateral channel 400 by the two support heads; then the pneumatic finger cylinder 321 drives the two support heads to open, so that the two support heads can tighten the two inner walls of the lateral channel 400, thereby realizing the grasping of the uncut-leg Z-shaped coil.

[0042] In some embodiments, the two support heads are spaced apart along a horizontal direction.

[0043] In some embodiments, when the untrimmed Z-shaped coil is delivered at the end of the linear vibrating track 22: First, the pneumatic finger cylinder 321 is moved to the feeding station 2 by the flipping and displacement assembly 31, and the two finger support heads 323 of the pneumatic finger cylinder 321 are brought closer to each other, and the two support heads that are brought closer to each other are brought closer to the end of the straight vibration track 22; it can be understood that the two support heads form a temporary extension of the end of the straight vibration track 22, and the two support heads are each located on one side of the temporary extension. Then, the uncut-leg Z-shaped coil is delivered at the end of the straight vibration track 22. Correspondingly, the uncut-leg Z-shaped coil is moved to be inserted by the two supports from the side channel 400. When the coil current limiting mechanism 5 is provided, the coil current limiting mechanism 5 can be set to a state that allows the uncut-leg Z-shaped coil to be delivered from the end of the straight vibration track 22. After the uncut Z-shaped coil is moved to the point where it is inserted into the side channel 400 by the two support heads, the support heads 323 of the two fingers of the pneumatic finger cylinder 321 are separated from each other, and the two support heads form a support to tighten the two inner walls of the side channel 400, so that the uncut Z-shaped coil is held on the gripping assembly 32. Next, the flipping and displacement components 31 are used to flip and transport the uncut Z-shaped coil to the cutting and loading station 4.

[0044] In some embodiments, the fixed arm 322 further has a stop block 324, which is used to block the uncut-leg zigzag coil after it has been moved to the point where it is passed through the two support heads from the side channel 400, so as to prevent the uncut-leg zigzag coil from being completely passed through the two support heads from the side channel 400, so as to block the uncut-leg zigzag coil against the two support heads.

[0045] In this way, when receiving an uncut-legs I-shaped coil, the position of the uncut-legs I-shaped coil relative to the two supports can be better ensured. For example, after the uncut-legs I-shaped coil is delivered from the end of the linear vibration track 22, it moves to the temporary extension formed by the two supports, and is held on the temporary extension by the stop block 324.

[0046] In some embodiments, the positioning stop 324 provides positioning abutment to the wing 100 of the uncut-leg Z-shaped coil.

[0047] In some embodiments, the positioning stop also constitutes a positioning stop engagement on the portion of the uncut Z-shaped coil near the wing.

[0048] In some embodiments, the flipping and displacement assembly 31 includes a height adjustment assembly 311, an electrically controlled rotation assembly 312 is provided on the adjustment end of the height adjustment assembly 311, and a gripping assembly 32 is provided on the rotation end of the electrically controlled rotation assembly 312.

[0049] The height adjustment component 311 can be adjusted in height. For example, the electric control rotation component 312 drives the gripping component 32 to rotate the uncut-leg Z-shaped coil gripped by the gripping component 180°, and then the height adjustment component 311 can drive it to move down to the lower cutting and loading station 4.

[0050] In some embodiments, the height adjustment component may be an electrically controllable linear adjustment component, such as a cylinder assembly or an electric actuator assembly.

[0051] If the height adjustment component is a cylinder assembly mounted on the equipment frame, the cylinder piston rod of the cylinder assembly constitutes the adjustment end of the height adjustment component.

[0052] In some embodiments, the electrically controlled rotating component is, for example, a motor rotating component, a rotary cylinder component, or other components that can be electrically driven to rotate.

[0053] For example, the electrically controlled rotating component is a rotary cylinder assembly mounted on the adjusting end of the height adjusting component, and the rotary table of the rotary cylinder corresponds to the rotating end of the electrically controlled rotating component. The gripping component (such as the cylinder body of a pneumatic finger cylinder) is set on the rotary table of the rotary cylinder.

[0054] In some embodiments, the inductor U-shaped coil lead-cutting device includes a coil lead-cutting and demolding mechanism 6. The coil lead-cutting and demolding mechanism 6 is used to receive the uncut U-shaped coil at the lead-cutting loading station 4, cut the leads of the uncut U-shaped coil, and perform the unloading operation of the cut U-shaped coil.

[0055] In some embodiments, the coil lead-cutting and demolding mechanism 6 is used to receive the uncut lead zig-shaped coil flipped and moved to the lead-cutting and loading station 4 by the coil flipping and loading mechanism 3, and to cut the lead of the uncut lead zig-shaped coil, as well as to perform the unloading operation of the cut lead zig-shaped coil.

[0056] In some embodiments, the coil shearing and demolding mechanism 6 includes a punching bottom mold 61, a bottom mold moving assembly 62, a coil two-wing punching assembly 63, a coil demolding assembly 64, and a punching station 65.

[0057] The bottom die moving assembly 62 is used to move the punching bottom die 61 to the shearing foot loading station 4 and the punching station 65.

[0058] The punching die 61 receives the uncut lead-shaped coil at the lead-cutting feeding station 4.

[0059] The coil wing punching assembly 63 is located above the punching station 65.

[0060] The bottom die moving assembly 62 moves the punching bottom die 61 to the punching station 65 and positions the uncut Z-shaped coil below the coil wing punching assembly 63.

[0061] The coil wing punching assembly 63 is used to punch and trim the untrimmed Z-shaped coil in the punching die 61 (e.g., shorten it to leave usable legs), so that the length of the two wings of the Z-shaped coil meets the product requirements.

[0062] After the punching is completed, the coil demolding assembly 64 demolds and unloads the zig-shaped coil in the punching die 61.

[0063] In some embodiments, the punching die 61 has a first wing punching die 611 and a second wing punching die 612.

[0064] The first wing punching die 611 and the second wing punching die 612 are spaced apart along the first horizontal direction, and a coil ridge receiving groove 613 is formed between the first wing punching die 611 and the second wing punching die 612.

[0065] The coil ridge receiving groove 613 has a top receiving opening and two lateral connecting openings extending along a second horizontal direction.

[0066] The first horizontal direction is set perpendicular to the second horizontal direction.

[0067] In some embodiments, when the support head 323 is present, the first horizontal direction is the same as the horizontal spacing direction of the two support heads.

[0068] In some embodiments, after flipping the uncut-leg zigzag coil, the flipping and displacement assembly 31 and the gripping assembly 32 can respectively place the uncut-leg zigzag coil downward on the punching bottom die 61, and make the ridge 200 of the uncut-leg zigzag coil located in the coil ridge receiving groove 613, and make the wing 100 of the uncut-leg zigzag coil located on the corresponding first wing punching lower die 611 and second wing punching lower die 612.

[0069] After the gripping component 62 cancels the gripping of the uncut-leg Z-shaped coil, the first wing punching die 611 and the second wing punching die 612 respectively form supports for the two wings of the uncut-leg Z-shaped coil.

[0070] In some embodiments, the bottom die moving assembly 62 is used to horizontally move the punching bottom die 61, so that the punching bottom die 61 moves between the shearing foot loading station 4 and the punching station 65.

[0071] In some embodiments, the bottom die moving assembly 62 moves horizontally to punch the bottom die 61 in the same direction as the second horizontal direction.

[0072] In some embodiments, the bottom mold moving assembly may employ electrically controlled linear drive components such as cylinder assemblies, electric push rod assemblies, and electric slide assemblies.

[0073] For example, the bottom mold moving assembly is an electric slide assembly, and the punching bottom mold is set on the moving end of the bottom mold moving assembly, that is, on the slide of the electric slide assembly, and the electric slide assembly drives the punching bottom mold to move.

[0074] In some embodiments, the coil wing punching assembly 63 includes a punching drive assembly 631 mounted on the equipment frame 1.

[0075] A punching drive assembly 631 is connected to a punching mounting base 632. The punching mounting base 632 is connected to a first wing cutter 633 that cooperates with the first wing punching die and a second wing cutter 634 that cooperates with the second wing punching die.

[0076] The punching drive assembly 631 drives the punching mounting base 632 to move up and down, and the cutting heads of the first wing cutter 633 and the second wing cutter 634 are both set downwards.

[0077] The spacing direction of the first wing cutter 633 and the second wing cutter 634 is the same as the spacing direction of the first wing punching die 611 and the second wing punching die 612.

[0078] During punching, the first wing cutter 633 cuts down from the side opposite to the second wing punching die on the first wing punching die. The support of the first wing punching die on one of the wing portions of the uncut coil allows the first wing cutter to cut off that wing portion after it cuts down. The second wing cutter 634 cuts downwards from the side opposite to the first wing punching die on the second wing punching die. The second wing punching die supports the other wing of the uncut Z-shaped coil, enabling the second wing cutter to cut off the other wing after cutting downwards.

[0079] In some embodiments, a coil positioning head 635 is also connected to the punching mounting base 632. The coil positioning head 635 is located between the first wing cutter 633 and the second wing cutter 634. The coil positioning head 635 corresponds to the opening 300 of the uncut-leg zigzag coil placed on the coil ridge receiving groove. The coil positioning head 635 is configured to be inserted into the lateral channel 400 of the uncut-leg zigzag coil through the opening 300 of the uncut-leg zigzag coil, thereby positioning the uncut-leg zigzag coil within the lateral channel 400 of the uncut-leg zigzag coil.

[0080] When the punching drive assembly 631 drives the punching mounting base 632 downward, the coil positioning head 635 first inserts into the lateral channel 400 of the uncut-leg zig-shaped coil (flipped to inverted) through the opening 300. It then cooperates with the first wing punching die 611 and the second wing punching die 612 to pre-position the uncut-leg zig-shaped coil. During the continued downward movement, the first wing cutter 633 and the second wing cutter 634 are in place to complete the punching of the corresponding wings.

[0081] In some embodiments, the punching die 61 is formed with punching guide holes 636 arranged vertically, and the punching mounting base 632 is connected with punching guide posts 637 that cooperate with the punching guide holes 636.

[0082] During the downward movement, the punching guide post 637 can be inserted into the punching guide hole 636 to form a guiding setting, making the punching alignment more accurate.

[0083] In some embodiments, the punching drive assembly is, for example, an electrically controlled up-and-down drive assembly such as a cylinder drive assembly or a hydraulic cylinder drive assembly, which can drive the punching mounting base to move linearly up and down.

[0084] In some embodiments, the coil demolding assembly 64 includes a demolding pusher 641 slidably disposed on the punching die 61. Correspondingly, the punching die 61 is provided with a demolding slide rail 642 that cooperates with the demolding pusher 641. The sliding direction of the demolding pusher 641 on the demolding slide rail 642 is the same as the second horizontal direction.

[0085] The demolding pusher 641 has a pusher part 643 corresponding to the coil ridge receiving groove 613.

[0086] When the demolding pusher 641 slides along the second horizontal direction on the demolding slide rail 642, the pusher part 643 correspondingly enters the coil ridge receiving groove 613 along the second horizontal direction to push the zigzag coil away from the coil ridge receiving groove 613.

[0087] Specifically, the pusher 643 enters the coil ridge receiving groove 613 from one of the side connections to push the zigzag coil out of the coil ridge receiving groove 613 from the other side connection.

[0088] After the zig-shaped coil is removed from the coil ridge receiving groove 613, the wings of the zig-shaped coil are removed from the support of the first wing punching die 611 and the second wing punching die 612, thereby falling to achieve the purpose of demolding and unmolding.

[0089] The demolding pusher 641 slides on the demolding slide rail 642, causing the pusher part 643 to push the Z-shaped coil to demold. The sliding state corresponding to the demolding is called the unloading state.

[0090] Correspondingly, the demolding pusher 641 can also slide on the demolding slide rail 642, causing the pusher part 643 to return to the non-entering coil ridge receiving groove 613. This sliding state is called the return state.

[0091] In some embodiments, the coil demolding assembly 64 further includes a first state adjustment assembly, which is used to switch the demolding pusher 641 between a feeding state and a return state on the demolding slide rail 642.

[0092] In some embodiments, the first state adjustment component includes a demolding drive component 644, which drives the demolding pusher 641 to put the demolding pusher 641 into a feeding state.

[0093] In some embodiments, the first state adjustment component further includes a first reset component, which is used to return the demolding pusher 641 from the unloading state to the return state.

[0094] In some embodiments, the demolding drive component and the first reset component are used in conjunction: when unloading is required, the drive end of the demolding drive component drives the demolding pusher to the unloading state by pushing; after unloading is completed, the drive end of the demolding drive component returns to its original position, and the first reset component can correspondingly return the demolding pusher from the unloading state to the return state.

[0095] In some embodiments, the demolding drive assembly may be an electrically controlled drive assembly such as a cylinder assembly or an electric push rod assembly. The demolding drive assembly 644 pushes along the second horizontal direction to drive the demolding push head 641.

[0096] For example, the demolding drive assembly is a cylinder assembly. The cylinder body of the cylinder assembly is mounted on the equipment frame. The piston rod of the cylinder assembly moves in the second horizontal direction. An extrusion seat 648 is connected to the piston rod of the cylinder assembly. The extrusion seat 648 corresponds to the demolding push head 641.

[0097] In some embodiments, the movement direction of the bottom mold moving component 62 in moving the punching bottom mold 61 from the punching station 65 to the shearing foot loading station 4 is opposite to the pushing direction of the demolding drive component (specifically, the top pressure seat 648) pushing the demolding push head 641 in the unloading state.

[0098] In some embodiments, the top pressure seat 348 corresponds to the side of the demolding pusher 641 away from the pusher section.

[0099] In some embodiments, the demolding drive assembly 644 is configured to push the demolding pusher 641 at the shearing foot loading station 4.

[0100] In some embodiments, the first reset component includes a first resilient reset member.

[0101] When the demolding pusher is in the unloading state, the first elastic reset member is in an elastic deformation state; after the driving end of the demolding drive assembly returns to its original position, the corresponding elastic deformation of the first elastic reset member is restored to drive the demolding pusher to return from the unloading state to the return state.

[0102] In some embodiments, the first elastic reset member includes a top pressure spring (not shown) disposed on the punching die. The top pressure spring is located between the punching die and the demolding pusher. When the demolding pusher is in the unloading state, the top pressure spring is pressed together by the punching die and the demolding pusher to undergo elastic deformation.

[0103] In some embodiments, the coil demolding assembly 64 further includes a positioning block 645 slidably disposed on the punching die 61, the sliding direction of the positioning block 645 on the punching die 61 being the same as the second horizontal direction.

[0104] The positioning block 645 has a stop portion 649 corresponding to another lateral communication port.

[0105] When the positioning block 645 slides on the punching die 61 along the second horizontal direction, the stop part 649 moves closer to the other side connection port along the second horizontal direction, or enters the coil ridge receiving groove 613 from the other side connection port, so as to prevent the zig-shaped coil or the undone zig-shaped coil from leaving the coil ridge receiving groove 613 from the other side connection port.

[0106] The sliding of the positioning block 645 on the punching die 61 causes the stop part 649 to form a sliding state that blocks the Z-shaped coil or the uncut Z-shaped coil, which is called the blocking state.

[0107] Correspondingly, the positioning block 645 can also slide on the punching die 61 to cause the stop part 649 to return to a position away from the other lateral communication port. This sliding state is referred to as the disengaged state.

[0108] In some embodiments, a sliding guide post 646 is connected to the positioning block 645 and is arranged along the second horizontal direction. A sliding guide hole that cooperates with the sliding guide post 646 is provided through the punching die 61. Through the sliding cooperation between the sliding guide post 646 and the sliding guide hole, the positioning block 645 can slide on the punching die 61.

[0109] Preferably, at least two sliding guide posts and corresponding sliding guide holes are provided.

[0110] In some embodiments, one end of the sliding guide post 646 away from the positioning block 645 passes through the sliding guide hole, and the end of the sliding guide post 646 passing through the sliding guide hole is connected to a force-receiving part 647.

[0111] The force-bearing part 647 corresponds to the driving end of the demolding drive assembly (specifically, the top pressure seat 648). That is, the driving end of the demolding drive assembly can push the demolding push head 641 and the force-bearing part 647, thereby causing the positioning block 645 to be in a disengaged state.

[0112] In some embodiments, the coil demolding assembly 64 further includes a second reset assembly for returning the positioning stop 645 from the disengaged state to the blocking state.

[0113] In some embodiments, the second reset component includes a second resilient reset member.

[0114] When the positioning block is in the disengaged state, the second elastic reset member is in the elastic deformation state; after the demolding drive assembly returns to its original position, the second elastic reset member recovers its corresponding elastic deformation to drive the positioning block to return from the disengaged state to the blocking state.

[0115] In some embodiments, the second elastic reset member includes a second top pressure spring (not shown) sleeved on the sliding guide post. The second top pressure spring is located between the force-bearing part and the punching die, that is, the second top pressure spring is sleeved on the end of the sliding guide post that passes through the sliding guide hole.

[0116] When the positioning block is in the disengaged state, the second top pressure spring is pressed together by the punching bottom die and the force-bearing part to undergo elastic deformation.

[0117] In some embodiments, in the second horizontal direction, and before the force-bearing portion and the demolding pusher are pushed by the drive end of the demolding drive assembly (specifically, the pusher seat 648): The distance between the force-bearing part and the drive end of the demolding drive assembly (specifically, the top pressure seat 648) is smaller than the distance between the demolding pusher and the drive end of the demolding drive assembly (specifically, the top pressure seat 648).

[0118] When the drive end of the demolding drive assembly pushes, the drive end of the demolding drive assembly first pushes the force-bearing part 647, and the positioning block 645 is initially in the disengaged state; as the push continues, the demolding push head 641 is then pushed and is in the unloading state; this causes the positioning block 645 to first disengage from the Z-shaped coil, and then the demolding push head 641 can smoothly push the Z-shaped coil away.

[0119] In some embodiments, when the coil lead-cutting and demolding mechanism completes the receiving of the uncut lead zig-shaped coil, the lead-cutting of the uncut lead zig-shaped coil, and the unloading of the zig-shaped coil, the punching bottom die 61 only needs to move back and forth once, which is more conducive to improving production efficiency.

[0120] Specifically, firstly, the punching bottom die 61 is located at the shearing foot loading station 4, and the coil flipping loading mechanism 3 inserts the flipped, uncut, Z-shaped coil into the coil ridge receiving groove 613; the coil flipping loading mechanism 3 cancels the gripping and returns to its original position; at this time, the positioning block 645 is in the blocking state, and the demolding push head 641 is in the returning state, to ensure that the uncut, Z-shaped coil can be smoothly placed on the coil ridge receiving groove 613, and to better hold the uncut, Z-shaped coil; Then, the bottom mold moving assembly 62 drives the punching bottom mold 61 to move to the punching station 65; the punching drive assembly 631 of the coil two-wing punching assembly drives the punching mounting base 632 downward, so that the punching guide post 637 is inserted into the punching guide hole 636, so that the coil positioning head 635 is inserted into the side channel 400 of the uncut-leg Z-shaped coil through the opening of the uncut-leg Z-shaped coil, and so that the first wing cutter 633 and the second wing cutter 634 punch and cut the two wings of the uncut-leg Z-shaped coil respectively, so that the punching quality is better; after the punching is completed, the punching drive assembly 631 drives the punching mounting base 632 upward to reset; Next, the bottom mold drive assembly 62 drives the punching bottom mold 61 to the shearing foot loading station 4. The demolding drive assembly 644 works to make the top pressure seat 648 push the force receiving part 647 first, so that the positioning block 645 is in the disengaged state. As the top pressure seat 648 continuously pushes the force receiving part 647, the top pressure seat 648 can contact the demolding push head 641 and push the demolding push head 641 into the unloading state. Thus, without the positioning block 645 blocking, the Z-shaped coil (after shearing) is pushed away from the coil ridge receiving groove 613, completing the unloading of the Z-shaped coil.

[0121] After the material is unloaded, the drive end of the demolding drive assembly 644 is reset to the position before the push, the demolding push head 641 is switched to the return state under the action of the first reset assembly, and the positioning block 645 is switched to the blocking state under the action of the second reset assembly.

[0122] When it is necessary to continuously receive uncut Z-shaped coils, cut the leads of uncut Z-shaped coils, and cut Z-shaped coils, the above process can be repeated to effectively improve production efficiency.

[0123] In this embodiment, the arrangement of the support head 323, the first wing punching die 611, the second wing punching die 612, the coil positioning head 635, and the positioning block 645 enables the uncut Z-shaped coil to be stably fed onto the punching die and to be punched stably.

[0124] In some embodiments, the coil lead shearing and demolding mechanism 6 further includes an ejector plate 66, ejector pins 67 connected to the ejector plate, and an ejector drive assembly 68 for driving the ejector plate. The ejector plate 66 is disposed on the drive end of the ejector drive assembly 68.

[0125] The positioning block 645 has a pin hole 69 through it, which is arranged along the second horizontal direction. The pin hole 69 corresponds to another side communication port, and the pin 67 corresponds to the pin hole 69.

[0126] The ejector drive assembly 68 is configured to drive the ejector plate 66 in a second horizontal direction, so that the ejector 67 passes through the ejector hole 69 and through another lateral communication port to press the uncut leaded zig-shaped coil or zig-shaped coil in the coil ridge receiving groove 613.

[0127] For example, during punching, the uncut coil is further pressed and positioned by the ejector pin, resulting in better punching quality.

[0128] For example, during demolding and unloading, ejector pins can be used to press down to prevent the zig-shaped coil from getting stuck on the positioning block.

[0129] In some embodiments, the ejector pin drive assembly may be an electrically controlled drive assembly such as a cylinder assembly or an electric actuator assembly.

[0130] For example, the ejector drive assembly is a cylinder assembly. The cylinder body of the cylinder assembly is mounted on the equipment frame. The piston rod of the cylinder assembly moves in the second horizontal direction, and the ejector plate 66 is connected to the piston rod of the cylinder assembly.

[0131] In this embodiment, tests showed that compared to the traditional clipping method, efficiency was improved by ≥10% and dimensional stability was improved by ≥5%.

[0132] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
