[0002] The structure of the iron core reactor is similar to that of a transformer, and includes an iron core and an iron yoke.

[0003] The iron yoke is generally formed by stacking individual iron yoke sheets and then extruding them through two angle irons.

[0004] At present, the stacking and installation of iron yoke sheets are basically done manually. When stacking, the number of iron yoke sheets that the assemblers take each time is not fixed, and they take them entirely based on experience, resulting in low production efficiency of the iron yoke. Summary of the invention

[0012] In one embodiment, before step S20, the iron yoke production method further includes: step S11: adjusting the size of the storage bin according to the parameters of the iron yoke to be produced.

[0013] In one embodiment, the yoke includes two opposite yoke clamps, a yoke sheet stack located between the two yoke clamps, and bolts passing through the yoke clamps and the yoke sheet stack. The yoke mounting platform includes: a platform body, having a platform mounting surface; a positioning mechanism, arranged on the platform mounting surface, the positioning mechanism having a positioning vertical surface; a length adjustment device, arranged in front and behind the positioning mechanism in the normal direction p of the positioning vertical surface, the length adjustment device extends along the normal direction p, the length adjustment device has a first positioning surface and a second positioning surface, and an installation gap of a predetermined length is provided between the positioning vertical surface and the first positioning surface.

DETAILED DESCRIPTION

[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0047] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein.

[0048] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0049] like Fig.24 As shown, the iron yoke production method of this embodiment includes: Step S20: Shearing the iron yoke raw material a predetermined number of times to form a predetermined number of iron yoke sheets 1, and feeding the multiple iron yoke sheets 1 into the storage bin 21 of the iron yoke stacking device 90. Step S30: Placing the iron yoke sheet pile 3 in the storage bin 21 on the discharge conveyor belt 30. Step S60: Determine whether the discharge conveyor belt 30 is full of iron yoke sheet piles 3, if not, execute step S20, if full, execute step S70. Step S70: Take out the multiple iron yoke sheet piles 3 on the discharge conveyor belt 30 to the iron yoke installation platform 100, and position and install the multiple iron yoke sheet piles 3.

[0050] Applying the technical solution of this embodiment, when the iron yoke is produced, the iron yoke sheets 1 are fed into the storage bin 21 one by one. When the number of iron yoke sheets 1 in the storage bin 21 reaches a predetermined number, the iron yoke sheet pile in the storage bin 21 forms a stacking unit. The stacking unit is placed on the discharge conveyor belt 30. Repeat the above steps until the discharge conveyor belt 30 is full of the iron yoke sheet pile 3. Then the assembler takes the iron yoke sheet pile 3 on the discharge conveyor belt 30 to the iron yoke mounting platform 100 for positioning and stacking. When the thickness of the multiple stacking units after stacking reaches the preset thickness, the multiple stacking units are fixed together by bolts to form the final iron yoke product. The above-mentioned iron yoke production method is applied to produce the iron yoke, so that during the stacking process of the iron yoke, the assembler only needs to take a predetermined number of stacking units, so that the stacking of the iron yoke has a regular pattern, thereby making the stacking efficiency higher.

[0051] like Fig.24As shown, in the present embodiment, the position of the discharge conveyor belt 30 opposite to the storage bin 21 is the place where the iron yoke sheets are piled, and the iron yoke production method further includes: Step S40: by setting a first sensor 60, it is determined in real time whether there is a pile of iron yoke sheets 3 at the place where the iron yoke sheets are piled, and if there is a pile of iron yoke sheets 3, step S50 is executed. Step S50: Move the discharge conveyor belt 30 forward a preset distance. The above steps enable the lowered pile of iron yoke sheets 3 to leave the place where the iron yoke sheets are piled, thereby providing a placement position for the next pile of iron yoke sheets 3. The above steps enable the actuator for placing the iron yoke sheet pile 3 to only be able to be lifted and moved, and the movement requirements for the above actuator are relatively low, thereby making the production cost of the actuator relatively low, thereby reducing the production cost of the iron yoke.

[0052] It should be noted that step S40 is a real-time judgment step, that is, step S40 is also executed synchronously during the execution of steps S20 and S30. In addition, if it is determined that there is no iron yoke sheet pile 3 at the iron yoke sheet pile placement location, it is continued to be judged whether there is an iron yoke sheet pile 3 at the iron yoke sheet pile placement location.

[0053] In this embodiment, the method for judging whether the discharge conveyor belt 30 is fully loaded with the iron yoke sheet pile 3 includes: a second sensor 80 is arranged at the tail of the discharge conveyor belt 30, and when the second sensor 80 senses the iron yoke sheet pile 3, it can send an in-place signal to the outside, and the control device judges that the discharge conveyor belt 30 is fully loaded with the iron yoke sheet pile 3 by receiving the in-place signal. The above judgment method is simple, and the cost of the equipment required for the judgment is low, thereby reducing the production cost of the iron yoke.

[0054] Of course, in other embodiments, the method for determining whether the discharge conveyor belt 30 is full of the iron yoke sheet pile 3 can also be: photographing the discharge conveyor belt 30 at predetermined intervals, and the control device can obtain the number of the iron yoke sheet piles 3 through the photographed pictures. When the number of the obtained iron yoke sheet piles 3 reaches the preset number, the control device determines that the discharge conveyor belt 30 is full of the iron yoke sheet piles 3.

[0055] In this embodiment, the storage bin 21 includes a receiving state and an open state, and the iron yoke stacking device 90 also includes a lifting mechanism 40, which includes a support structure 41 and a first lifting driver 42 for driving the support structure 41 to rise and fall. The method for placing the iron yoke sheet stack 3 in the storage bin 21 on the discharge conveyor belt 30 includes: extending the support structure 41 into the storage bin 21; switching the storage bin 21 to an open state; and making the support surface of the support structure 41 lower than or flush with the conveying surface of the discharge conveyor belt 30. The above structure enables the iron yoke sheet stack 3 to be stably placed on the discharge conveyor belt 30, which ensures that the iron yoke sheet stack 3 placed on the discharge conveyor belt 30 is relatively neat on the one hand, and reduces the impact of the iron yoke sheet stack 3 on the discharge conveyor belt 30 on the other hand, thereby ensuring the service life of the discharge conveyor belt 30 and reducing the noise generated by production.

[0056] In the present embodiment, the storage bin 21 has an opening at the bottom, and the method for allowing the support structure 41 to extend into the storage bin 21 includes: lowering the storage bin 21, and the opening avoids the support structure 41. Specifically, in the present embodiment, the process of placing and lowering the iron yoke sheet stack 3 includes a first descending section and a second descending section. Among them, in the first descending section, the iron yoke sheet stack 3 is limited by the storage bin 21 and follows the storage bin 21 to descend; in the second descending section, the iron yoke sheet stack 3 follows the support structure 41 to descend. The above method enables the iron yoke sheet stack 3 to be limited in one of the stages of the descent. Compared with the scheme of "raising the support structure, and the support structure extends upward into the storage bin through the opening" (the iron yoke sheet stack is not limited in the entire process of placement and descent), it can better ensure the neatness of the iron yoke sheet stack 3, which is convenient for subsequent stacking and installation.

[0057] like Fig.24 As shown, in this embodiment, before step S20, the iron yoke production method further includes: step S11: adjusting the size of the storage bin 21 according to the parameters of the iron yoke to be produced. The above structure enables the above production method to produce iron yokes of different models, thereby having better versatility.

[0058] Preferably, in this embodiment, before step S20, the iron yoke production method further includes: step S12: adjusting the position of the support structure 41 so that the projection of the support structure 41 in the horizontal plane is located in the middle of the projection of the opening in the horizontal plane. The above method ensures that when the support structure 41 supports the iron yoke sheet stack 3, the iron yoke sheet stack 3 will not fall over, thereby ensuring that the iron yoke sheet stack 3 can be stably placed on the discharge conveyor belt 30.

[0059] In this embodiment, the iron yoke includes two opposite iron yoke clamps 2, an iron yoke sheet stack 3 located between the two iron yoke clamps 2, and bolts passing through the iron yoke clamps 2 and the iron yoke sheet stack 3. The iron yoke installation platform 100 includes: a platform body 110, a positioning mechanism 120, and a length adjustment device 140. Among them, the platform body 110 has a platform installation surface 111. The positioning mechanism 120 is arranged on the platform installation surface 111, and the positioning mechanism 120 has a positioning vertical surface 122. The length adjustment device 140 and the positioning mechanism 120 are arranged front and back in the normal direction p of the positioning vertical surface 122, and the length adjustment device 140 extends along the normal direction p. The length adjustment device 140 has a first positioning surface and a second positioning surface, and there is a mounting gap of a predetermined length between the positioning vertical surface 122 and the first positioning surface. Step S70 includes: Step S71: clamp one of the iron yoke clamps 2 in the mounting gap; Step S73: the outer surface of the other iron yoke clamp 2 is flush with the second positioning surface; Step S74: take out the multiple iron yoke sheet stacks 3 on the unloading conveyor belt 30 to the installation space between the two iron yoke clamps 2; Step S76: insert the bolts through the iron yoke clamp 2 and the iron yoke sheet stack 3. On the one hand, the above installation steps enable the position of the previous stacking unit to remain unchanged when stacking the next stacking unit, thereby improving the iron yoke production efficiency. On the other hand, since the installation space is fixed, the installer only needs to take multiple iron yoke sheet stacks 3 to fill the installation space, and there is no need to repeatedly measure the thickness of the iron yoke, thereby improving the iron yoke production efficiency.

[0060] Due to the different target thicknesses of the iron yokes to be produced, the thickness of the multiple stacking units stacked together may not meet the target thickness. In order to solve the above problem, in this embodiment, between step S74 and step S76, step S70 also includes: step S75: determine whether the iron yoke sheet stack 3 fills the installation space. If not, fill the installation space with iron yoke sheets 1 until the installation space is filled. The above method achieves the purpose of achieving different target thicknesses of the iron yoke by filling the installation space with a small amount of iron yoke sheets 1 to fill the installation space.

[0061] In this embodiment, the distance between the first positioning surface and the second positioning surface in the normal direction p is adjustable, the first positioning surface forms a fixed positioning surface 142, and the second positioning surface forms a movable positioning surface 145. Between step S71 and step S73, step S70 further includes: adjusting the distance between the fixed positioning surface 142 and the movable positioning surface 145 according to the parameters of the iron yoke to be produced. The above structure enables the above production method to produce iron yokes of different models, thereby having better versatility.

[0062] The iron yoke production method of this embodiment adopts the following iron yoke stacking production line. Figure 1 , Figure 2 and Fig.19As shown, the iron yoke stacking assembly line includes: an iron yoke stacking device 90 and an iron yoke mounting platform 100. Among them, the iron yoke stacking device 90 includes a feeding mechanism 10, a receiving mechanism 20 and a control device electrically connected to the feeding mechanism 10, the feeding mechanism 10 is used to convey the iron yoke sheet 1, the control device controls the number of iron yoke sheets 1 conveyed, the receiving mechanism 20 is located on one side of the feeding outlet of the feeding mechanism 10, and the receiving mechanism 20 includes a storage bin 21 for storing the iron yoke sheets 1. The iron yoke mounting platform 100 includes a platform body 110 and a positioning mechanism 120, the platform body 110 has a platform mounting surface 111, the positioning mechanism 120 is arranged on the platform mounting surface 111, and the positioning mechanism 120 has a positioning vertical surface 122. Specifically, pieces of iron yoke sheets are fed into the storage bin 21 through the feeding mechanism 10, and when the number of iron yoke sheets in the storage bin 21 reaches a predetermined number, the iron yoke sheets in the storage bin 21 form a stacking unit. The assembler takes the first generated stacking unit onto the platform body 110, and makes the first stacking unit close to the positioning facade 122 for pre-positioning. Then, the subsequently generated stacking unit is placed close to the previous stacking unit. When the thickness of the multiple stacking units after stacking reaches the preset thickness, the multiple stacking units are fixed together by bolts to form a final iron yoke product. The above-mentioned iron yoke stacking assembly line is used to make the iron yoke. On the one hand, during the stacking process of the iron yoke, the assembler only needs to take a predetermined number of stacking units, so that the stacking of the iron yoke follows a regular pattern, thereby making the stacking efficiency higher. On the other hand, the presence of the positioning mechanism 120 enables the position of the previous stacking unit to remain unchanged when stacking the next stacking unit, thereby improving the production efficiency of the iron yoke.

[0063] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the storage bin 21 includes a receiving state and an open state. When the storage bin 21 is in the receiving state, the iron yoke sheet 1 can be stored in the storage bin 21. The iron yoke stacking device 90 also includes: a discharge conveyor belt 30, part of which is located directly below the storage bin 21. When the storage bin 21 is in the open state, the iron yoke sheet pile in the storage bin 21 can be placed on the discharge conveyor belt 30. Specifically, when the number of iron yoke sheets 1 in the storage bin 21 reaches a predetermined number, the iron yoke sheet pile in the storage bin 21 forms a stacking unit. Then the storage bin 21 is switched to the open state, and the iron yoke sheet pile is placed on the discharge conveyor belt 30, and then transported out through the discharge conveyor belt 30. The above structure allows the installer to directly take it off the discharge conveyor belt 30 when taking the stacking unit, without having to take it out from the storage bin 21, so it is convenient for the installer to install, thereby improving the assembly efficiency of the iron yoke.

[0064] Since the iron yoke stack is heavy, if the storage bin 21 is opened, the iron yoke stack will fall directly onto the discharge conveyor belt 30, which will cause the discharge conveyor belt 30 to be easily damaged and cause a lot of noise. Figure 2 , Figure 3 , Figure 5 , Figure 7 and Fig.14 As shown, in this embodiment, the iron yoke stacking device also includes a lifting mechanism 40, which includes a support structure 41 and a first lifting driver 42 for driving the support structure 41 to rise and fall, and the support structure 41 includes a support position extending into the storage bin 21 and a placement position lower than the conveying surface of the discharge conveyor belt 30. Specifically, before the storage bin 21 is switched to the open state, the support structure 41 of the lifting mechanism 40 is located at the support position, so that the iron yoke sheet stack in the storage bin 21 will be supported by the support structure 41. Then the storage bin 21 is switched to the open state, and the support structure 41 is lowered to the placement position by the first lifting driver 42, at which time the iron yoke sheet stack is placed on the conveying surface of the discharge conveyor belt 30, and finally conveyed out by the discharge conveyor belt 30. The above structure enables the iron yoke sheet stack to be gently placed on the conveying surface of the discharge conveyor belt 30, which, on the one hand, prevents the discharge conveyor belt 30 from being impacted and ensures the service life of the discharge conveyor belt 30, and on the other hand, reduces the noise generated by production.

[0065] Since different iron yoke products have different corresponding lengths, if the supporting points of the iron yoke stack are fixed, the supporting stability of the longer iron yoke stack may be poor and it may easily fall over. Figure 2 , Figure 3 and Fig.14 As shown, in this embodiment, the lifting mechanism 40 also includes a first slide rail 43 provided at the driving end of the first lifting driver 42 and a plurality of first sliders 44 movably provided on the first slide rail 43. The first slider 44 can be locked on the first slide rail 43 by a locking member. The extension direction of the first slide rail 43 is the same as the feeding direction n. The support structure 41 includes a plurality of support columns, which are connected to the first sliders 44. For iron yoke sheet stacks of different lengths, the positions of the plurality of first sliders 44 can be adjusted to achieve the adjustment of the positions of the plurality of support columns, and finally the position of the support point of the iron yoke sheet stack can be adjusted to meet the production of iron yokes of different lengths.

[0066] Due to the different widths of different iron yoke products, the support surface at the top of the support column should be designed to be larger, which will also cause the support to fall over when the iron yoke stack with a wider width is supported. Fig.14 and Fig.15As shown, in this embodiment, the support column includes a column body 411 and a rotary block 412 arranged on the top of the column body 411, the cross-section of the rotary block 412 is rectangular, and the rotary block 412 is connected to the column body 411 through a locking piece. Specifically, when supporting a narrow iron yoke sheet pile, the extension direction of the long side of the rotary block 412 can be made the same as the feeding direction n. When supporting a wide iron yoke sheet pile, the locking piece can be loosened, and then the rotary block 412 can be rotated so that the extension direction of the long side of the rotary block 412 is perpendicular to the feeding direction n, and then the locking piece can be locked. The above structure allows iron yoke sheet piles of different widths to be stably supported to meet the production of iron yokes of different widths.

[0067] like Figure 2 , Figure 3 , Figure 5 and Fig.16 As shown, in the present embodiment, the material receiving mechanism 20 includes a second lifting driver 22 for driving the storage bin 21 to rise and fall. Specifically, when one stacking unit is stacked, the second lifting driver 22 drives the storage bin 21 to descend, which causes the top end of the support column to gradually extend into the storage bin 21 to lift the iron yoke sheet pile. After the support column lifts up the iron yoke sheet pile, the material receiving mechanism 20 is switched to an open state, and then the second lifting driver 22 drives the material receiving mechanism 20 to return to its initial position to receive the next stacking unit. Compared to the solution of driving the support column to extend into the storage bin, the solution of the present embodiment shortens the time required to place the iron yoke sheet pile on the discharge conveyor belt 30, thereby making the stacking of the iron yoke sheet pile more efficient.

[0068] like Figure 2 , Figure 3 , Figure 5 , Fig. 9 , Fig.12 , Figures 16 to 18 As shown, in this embodiment, the storage bin 21 includes two receiving upright plates arranged opposite to each other in a direction perpendicular to the feeding direction n, the receiving upright plates include an upright plate body 213 and a support plate 214 located at the bottom of the upright plate body 213 and extending toward the other receiving upright plate, and the receiving mechanism 20 also includes a material discharge driver 23, which drives the two receiving upright plates to move toward or away from each other so that the storage bin 21 is switched between a receiving state and an open state. The above structure is simple and has low production cost.

[0069] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the material receiving mechanism 20 further includes a first base frame 24 , and the second lifting drive 22 is disposed on the first base frame 24 .

[0070] like Figure 5 , Figure 8 , Fig.11 and Fig.16 As shown, in this embodiment, the receiving mechanism 20 also includes a first connecting plate 25 connected to the driving end of the second lifting driver 22, and the first connecting plate 25 is provided with second slide rails 26 at both ends in the feeding direction n, and the second slide rails 26 extend in a direction perpendicular to the feeding direction n. Two second sliders 27 are provided on each second slide rail 26, and the receiving vertical plate is connected to the corresponding two second sliders 27. Specifically, taking the direction perpendicular to the feeding direction n as the left and right direction, one of the receiving vertical plates is connected to the second slider 27 on the left side of the two second slide rails 26, and the other receiving vertical plate is connected to the second slider 27 on the right side of the two second slide rails 26. In the above structure, the second slide rail 26 plays a guiding role, so that the two receiving vertical plates move toward or away from each other along the preset direction under the action of the driver. The above structure is simple, stable and reliable.

[0071] like Figure 6 , Fig.10 , Figures 16 to 18 As shown, in this embodiment, the receiving mechanism 20 also includes a limit block 251 arranged at the middle of the bottom surface of the first connecting plate 25 and two limit arms 252 arranged at the edge of the first connecting plate 25 and extending outward in a direction perpendicular to the feeding direction n, at least part of the limit block 251 is located between the two second sliders 27, the receiving mechanism 20 also includes two baffles, the limit end 253 of the limit arm 252 is arranged on the outside of the baffle, the receiving vertical plate is connected to the second slider 27 through the baffle, and the material discharge driver 23 is a cylinder, the cylinder includes two telescopic ends 231 arranged oppositely, and the two telescopic ends are respectively connected to the inner surfaces of the two baffles to drive the two baffles to approach or separate. Specifically, when the storage bin 21 is in the receiving state, the inner surfaces of the two second sliders 27 abut against the limit block 251, and the above structure makes it impossible for the two baffles connected to the two second sliders 27 to continue to move toward each other even if the telescopic end 231 has a tendency to continue to shrink, that is, the two receiving vertical plates connected to the two baffles cannot continue to move toward each other. When the storage bin is in an open state, the outer side surfaces of the two baffles are limitedly matched with the limit end 253. The above structure makes it impossible for the two material receiving uprights connected to the two baffles to continue to move away from each other even if the telescopic end 231 has a tendency to continue to extend. Therefore, the above structure enables the two material receiving uprights to move within a predetermined larger displacement range, thereby shortening the time for the two material receiving uprights to return to the initial position, thereby improving the stacking efficiency. It should be noted that it is only necessary to satisfy that the two material receiving uprights have a channel that can pass through the iron yoke sheet stack when in the open state. Specifically, in this embodiment, the distance between the limit end 253 on the left and the left end face of the limit block 251 is equal to the distance between the limit end 253 on the right and the right end face of the limit block 251, and the above structure enables the two material receiving uprights to move symmetrically. Symmetrical movement can further shorten the time for the two material receiving uprights to return to the initial position, thereby improving the stacking efficiency.

[0072] like Figure 5 , Figure 8 , Fig. 9 , Fig.11 , Figures 16 to 18 As shown, in this embodiment, the two baffles are respectively a first baffle 281 stationary relative to the first connecting plate 25 and a second baffle 282 moving relative to the first connecting plate 25, the receiving plate includes a first receiving plate 211 and a second receiving plate 212, the first baffle 281 includes a first baffle body 2811 and a connecting member 2812, the first receiving plate 211 is connected to the first baffle body 2811 and the second slider 27 through the connecting member 2812, the second baffle 282 includes a second baffle body 2821, and a third slide rail 282 connected to the second baffle body 2821 2 and a third slider 2823 disposed on the third slide rail 2822, the third slide rail 2822 extends in a direction perpendicular to the feeding direction n, the third slider 2823 and the third slide rail 2822 form a slide rail assembly, the second receiving plate 212 is connected to the second baffle body 2821 and the second slider 27 through the slide rail assembly, the receiving mechanism 20 also includes a second width adjustment mechanism 29 disposed on the second baffle body 2821, the second width adjustment mechanism 29 includes an adjustment block 291 that moves in a direction perpendicular to the feeding direction n, and the second receiving plate 212 is connected to the adjustment block 291. When the width of the iron yoke sheet is large, the second width adjustment mechanism 29 can be adjusted to make the adjustment block 291 move toward the first receiving plate 211, so that the second receiving plate 212 connected to the adjustment block 291 can also move toward the first receiving plate 211, so that no matter the storage bin 21 is in the receiving state or the open state, the distance between the two receiving plates is correspondingly reduced. When the width of the iron yoke sheet is large, the second width adjustment mechanism 29 can be adjusted to make the adjustment block 291 move away from the first material receiving plate 211, so that the second material receiving plate 212 connected to the adjustment block 291 can also move away from the first material receiving plate 211, so that no matter whether the storage bin 21 is in the material receiving state or the open state, the distance between the two material receiving plates is correspondingly reduced. Therefore, the above structure can adjust the distance between the two material receiving plates according to the actual width of the iron yoke sheet while ensuring that the storage bin 21 can switch between the material receiving state and the open state, thereby improving the versatility of the iron yoke stacking device.

[0073] When the iron yoke pieces are fed into the storage bin 21, the iron yoke pieces will move forward under the action of inertia, and the position of the forward movement is uncertain. This results in poor uniformity of the end faces of the stacked iron yoke pieces. In order to solve the above problem, Figures 16 to 18As shown, in this embodiment, the material receiving mechanism 20 includes a third baffle 215 disposed on the material receiving vertical plate, the third baffle 215 is located between the two material receiving vertical plates, and the third baffle 215 is adjustably arranged in the feeding direction n. The above structure enables the iron yoke sheet sliding forward under the action of inertia to be stopped by the third baffle 215, thereby preventing the iron yoke sheet from moving too far, thereby improving the uniformity of the end surface of the stacked iron yoke sheet pile. Preferably, in this embodiment, the third baffle 215 is arranged on the second material receiving vertical plate 212.

[0074] like Figure 3 , Fig. 9 and Fig.14 As shown, in this embodiment, the iron yoke stacking device also includes a position adjustment mechanism 50, which is arranged on the first base frame 24. The position adjustment mechanism 50 cooperates with the lifting mechanism 40 to make the projection of the supporting structure 41 in the horizontal plane located in the middle of the projections of the two receiving vertical plates in the horizontal plane, so that the supporting point of the iron yoke sheet stack can be located in the middle of the iron yoke sheet stack in the left and right directions, thereby preventing the iron yoke sheet stack from tipping over.

[0075] like Figure 3 , Fig. 9 and Fig.13 As shown, in this embodiment, the extension direction of the discharge conveyor belt 30 is perpendicular to the feeding direction n of the feeding mechanism 10, and the discharge conveyor belt 30 is a plurality of discharge conveyor belts arranged at intervals along the feeding direction n, and at least one of the plurality of discharge conveyor belts 30 is movably arranged in the feeding direction n. The above structure enables the iron yoke stacking device to output iron yoke sheet stacks of different lengths by adjusting the distance between the discharge conveyor belts 30, thereby being able to produce iron yokes of different models, thereby improving the versatility of the iron yoke stacking device. In addition, the above structure can reduce the cost of the discharge device, thereby reducing the cost of the entire iron yoke stacking device.

[0076] like Figure 3 , Fig. 9 and Fig.13 As shown, in this embodiment, the receiving mechanism 20 includes a first base frame 24, which is formed by connecting a plurality of support beams, and a groove 241 is provided on the outer surface of the support beam, and the iron yoke stacking device further includes: a second connecting plate 70, and the discharge conveyor belt 30 is connected to the support beam through the second connecting plate 70 and a fastener, and the fastener is connected in the groove 241. Specifically, when adjusting the distance between two adjacent discharge conveyor belts 30, the fastener can be loosened first, and then the discharge conveyor belt 30 is moved to a preset position, and then the fastener can be tightened.

[0077] like Fig.14 and Fig.15As shown, in this embodiment, the discharge conveyor belt 30 includes a conveyor belt body and a conveyor belt driver for driving the conveyor belt body to move, and the iron yoke stacking device also includes: a first sensor 60. The first sensor 60 is used to detect whether the iron yoke sheet 1 falls onto the discharge conveyor belt 30. The conveyor belt driver and the first sensor 60 are both electrically connected to the control device. Specifically, when the first sensor 60 receives a placement signal, the first sensor 60 sends the placement signal to the control device, and after receiving the signal, the control device controls the conveyor belt driver to work, so that the discharge conveyor belt 30 moves a predetermined distance. The above structure enables multiple stacking units to be placed on an entire discharge conveyor belt 30, indicating the efficiency of the iron yoke stacking.

[0078] like Figure 3 As shown, in this embodiment, the iron yoke stacking device further includes: a second sensor 80 electrically connected to the control device and a prompting device, and the second sensor 80 is arranged at the tail of the discharge conveyor belt 30. The prompting device is electrically connected to the control device. Specifically, when the stacking unit is conveyed to the tail of the discharge conveyor belt 30, the second sensor 80 receives an in-place signal, and the second sensor 80 sends the in-place signal to the control device. After receiving the signal, the control device sends a prompting signal to the prompting device to remind the assembler to take the stacking unit to proceed to the next assembly step.

[0079] like Figures 2 to 5 As shown, in this embodiment, the feeding mechanism 10 includes a second base frame 11, a feed conveyor belt 12 arranged on the second base frame 11, and a first width adjustment mechanism 13. The first width adjustment mechanism 13 includes two limit plates 131 extending along the feeding direction n and an adjustment member 132. The two limit plates 131 are arranged relative to each other in a direction perpendicular to the feeding direction n, and the two limit plates 131 are located directly above the feed conveyor belt 12. The adjustment member 132 adjusts the width between the two limit plates 131. Specifically, when the iron yoke is wider, the width between the two limit plates 131 can be increased by the adjustment member 132; when the iron yoke is narrower, the width between the two limit plates 131 can be reduced by the adjustment member 132. The above structure enables both the wider iron yoke and the narrower iron yoke to be placed along the preset direction, so that the iron yoke can be smoothly fed into the storage bin 21.

[0080] like Figures 19 to 22 As shown, in this embodiment, the iron yoke mounting platform 100 also includes: a length adjustment device 140, the length adjustment device 140 and the positioning mechanism 120 are arranged front and back in the normal direction p of the positioning vertical surface 122, the length adjustment device 140 has a fixed positioning surface 142 and a movable positioning surface 145, the distance between the fixed positioning surface 142 and the movable positioning surface 145 in the normal direction p is adjustable, and there is an installation gap of a predetermined length between the positioning vertical surface 122 and the fixed positioning surface 142.

[0081] By applying the technical solution of this embodiment, before assembling the iron yoke, the length adjustment device 140 is first adjusted to a preset length according to actual needs, and then one of the iron yoke clamps 2 is clamped between the positioning vertical surface 122 and the fixed positioning surface 142 (i.e., within the installation gap), and the outer surface of the other iron yoke clamp 2 is made flush with the movable positioning surface 145, and then multiple stacking units are filled between the two iron yoke clamps 2. Finally, the two iron yoke clamps 2 are bolted to clamp the multiple iron yoke sheets 1 in the middle to form an iron yoke. The above-mentioned installation platform eliminates the need for installers to repeatedly measure whether the thickness of the iron yoke meets the preset standard when installing the iron yoke, thereby saving assembly time and improving the assembly efficiency of the iron yoke.

[0082] It should be noted that if after multiple stacking units are filled between two yoke clamps 2, there is still a gap between the last stacking unit and the yoke clamp 2 next to it, the installer can insert a small amount of yoke sheet 1 into the gap to fill it up. After it is filled up, the bolts can be inserted for installation.

[0083] It should also be noted that, in this embodiment, the normal direction p and the feeding direction n are opposite.

[0084] like Figures 19 to 21 As shown, in this embodiment, the positioning mechanism 120 includes a plurality of positioning upright plates 121 arranged at intervals along a direction q perpendicular to the normal direction p, and the side surfaces of the positioning upright plates 121 form positioning vertical surfaces 122. The above structure enables the iron yoke clamp 2 to have a plurality of positioning points in its length direction, thereby ensuring the accuracy of the position of the iron yoke clamp 2, and further ensuring that the thickness of the product after filling the iron yoke sheet 1 can reach a preset value, avoiding repeated measurements, and saving assembly time.

[0085] If the position of the positioning plate 121 is fixed and the yoke mounting platform is required to have the same positioning effect on yoke clamps 2 of different lengths, more positioning plates 121 need to be provided. However, the above structure makes the production cost of the yoke mounting platform higher. Figures 19 to 22 As shown, in this embodiment, the positioning mechanism 120 also includes a fourth slide rail 125 extending along the direction q, and a plurality of positioning uprights 121 are slidably disposed on the fourth slide rail 125. Specifically, when a longer iron yoke needs to be installed, the positioning uprights 121 can be slid to lengthen the distance between two adjacent positioning uprights 121, so as to ensure that the multiple positioning points of the iron yoke clamp 2 are distributed more evenly in the length direction thereof, and finally ensure the accuracy of the position of the iron yoke clamp 2; when a shorter iron yoke needs to be installed, the positioning uprights 121 can be slid to shorten the distance between two adjacent positioning uprights 121, so as to ensure that the multiple positioning points of the iron yoke clamp 2 are distributed more evenly in the length direction thereof, and finally ensure the accuracy of the position of the iron yoke clamp 2.

[0086] like Fig. 20 and Fig. 22 As shown, in this embodiment, the positioning vertical plate 121 includes a horizontal plate 123 and a vertical plate 124 connected to the end of the horizontal plate 123, the surface of the vertical plate 124 away from the horizontal plate 123 forms a positioning vertical surface 122, and the horizontal plate 123 is provided with a matching hole for penetrating the fourth slide rail 125. The above structure is simple, easy to process, low in production cost, and good in strength.

[0087] If the platform installation surface 111 is a horizontal surface, the iron yoke piece 1 is prone to tipping over when it is placed, and the installer needs to stand up the iron yoke piece 1, which affects the production efficiency. Fig.19 and Fig. 22 As shown, in the present embodiment, the platform mounting surface 111 gradually tilts downward in the direction from the movable positioning surface 145 to the fixed positioning surface 142. Specifically, the positioning vertical surface 122 of the positioning vertical plate 121 is perpendicular to the platform mounting surface 111, which makes the positioning vertical surface 122 actually an inclined surface. When the first iron yoke sheet 1 is placed on the platform mounting surface 111, the iron yoke sheet 1 can be pressed on the positioning vertical plate 121 under the action of the component force of gravity. Then, when the second iron yoke sheet 1 is placed, the iron yoke sheet 1 can be pressed on the first iron yoke sheet 1 under the action of the component force of gravity, and so on, until all the iron yoke sheets 1 are filled. Therefore, the above structure enables the iron yoke sheet 1 to only tilt in the direction required for installation, thereby ensuring that production efficiency is not affected.

[0088] It should be noted that the inclination angle of the platform mounting surface 111 only needs to be less than 90°.

[0089] like Fig.23 As shown, in this embodiment, the length adjustment device 140 includes a base 141 and a pull rod 144 movably disposed on the base 141, a fixed positioning surface 142 is located on the base 141, and an end of the pull rod 144 away from the positioning mechanism 120 forms a movable positioning surface 145. Specifically, the pull rod 144 is pulled out or retracted a certain distance according to the actual length requirements, and then the base 141 and the pull rod 144 are fixed by fasteners to achieve length adjustment. The above structure is simple and easy to implement.

[0090] like Fig.19 and Fig.23As shown, in this embodiment, a mounting groove 143 extending along the normal direction p of the positioning vertical surface 122 is provided on the base 141, and a pull rod 144 is movably provided in the mounting groove 143, and the pull rod 144 is connected to the base 141 through a fastener. The above structure allows the pull rod 144 to be hidden in the base 141, so that the outer surface of the length adjustment device 140 can be relatively flat, so that the side wall of the stacked iron yoke sheet pile close to the length adjustment device 140 can also be relatively neat, which is convenient for the subsequent insertion of bolts, and finally improves the production efficiency of the iron yoke.

[0091] like Fig.19 and Fig. 22 As shown, in this embodiment, the iron yoke installation platform further includes: a bracket 150, and the platform body 110 is arranged on the bracket 150. The above structure makes the platform installation surface 111 higher, which is convenient for installation personnel to assemble and reduces the labor intensity of installation personnel.

[0092] like Fig.19 and Fig. 22 As shown, in this embodiment, the bracket 150 includes a bracket body 151 and a moving wheel 152 disposed at the bottom of the bracket body 151. The above structure makes the iron yoke mounting platform more flexible and can be easily moved to any position according to different needs, thereby improving the convenience of using the iron yoke mounting platform.
