As shown in fig. 1 to 3, 8, 11, 13, and 26, the iron core machining system of the present embodiment includes: a material receiving and stacking machine 155, a rubber strip bundling machine 72, an iron core clamping and transferring machine 74, an iron core bundling and transferring machine 97 and an iron core assembling machine 156. Wherein, receive material stacker 155 has feed bin 3, and feed bin 3 has the storage space of vertical extension, and the upper portion opening of feed bin 3 forms the feeding. The glue bundler 72 has a bundler position. The core clamping transfer machine 74 is capable of transferring the stack 148 of core sheets in the magazine 3 to the binding station. The core binding transfer machine 97 transfers the core segment stack 148 to the core assembling machine 156, and the core assembling machine 156 assembles the plurality of core segment stacks 148 into a core.

By using the technical scheme of the embodiment, during iron core assembly, a piece of iron core sheet is collected in the storage bin 3 through the material collecting and stacking machine 155, the material is collected and stacked, then the iron core sheet stack in the storage bin 3 is transferred to the bundling position through the iron core clamping and transferring machine 74, and the iron core sheet stack 148 is bundled by the adhesive tape bundling machine 72. After the bundling is completed, the core stack is transferred to a predetermined position by an iron core bundling transfer machine 97, and finally the plurality of core stacks 148 are placed in the iron core assembling machine 156 and bonded to form a final iron core. The iron core processing system enables the stacking and bundling of the iron core sheets and the assembly of the iron core sheet stack to be completed through a machine, so that the iron core production efficiency is high, and finished products are more neat.

Note that the "the core binding transfer machine 97 transfers the core segment stack 148 to the core assembling machine 156" includes two schemes, one scheme is that the core binding transfer machine 97 transfers the core segment stack 148 to around the core assembling machine 156; another option is for the core tying transfer machine to transfer the stack of core sheets 148 directly to the core assembly machine 156. Specifically, this embodiment is the first scheme.

As shown in fig. 1, 24 and 25, in the present embodiment, the iron core processing system further includes: the flow line 157, the flow line 157 includes a frame 162, a core stack conveyor 163 disposed on the frame 162, and a conveyor driving device 167 for driving the core stack conveyor 163 to move, and the core stack conveyor 163 extends from the core binding transfer machine 97 toward the core assembling machine 156. The transmission mode is simple, the reliability of the transportation is strong, and the cost is low. Of course, in other embodiments not shown in the figures, the core tying transfer machine may transfer the stack of core sheets 148 to the core assembly machine 156 by a robotic arm.

As shown in fig. 1 and 24, in the present embodiment, the iron core machining system further includes: a control device, a belt drive 167 electrically connected to the control device, and the flow line 157 further includes a first sensor 164 located at the loading end of the stack conveyor 163, the first sensor 164 electrically connected to the control device. Specifically, when the core binding transfer machine 97 places the core stack at the feeding end of the core stack conveyor 163, the first sensor 164 senses the core stack 148 and transmits an in-position signal to the control device, and the control device controls the conveyor driving device 167 to operate so that the core stack conveyor 163 moves forward by a predetermined distance. After moving a predetermined distance, the stack 148 is moved away from the first sensor 164, and after the next stack 148 is placed on the loading end, the first sensor 164 sends a position signal to the outside, and so on. The above-described structure enables the core stack 148 to be automatically and continuously conveyed around the core assembling machine 156, reducing the labor intensity of workers.

As shown in fig. 1 and 24, the flow line 157 further includes a second sensor 165 located at the blanking end of the core stack conveyor 163, the second sensor 165 being electrically connected to the control device. Specifically, when the streamline 157 transports a preset number of core-sheet stacks 148, the core-sheet stack 148 close to the blanking end gradually moves to the second sensor 165 as the core-sheet stack conveyor 163 moves. The second sensor 165 sends a detection signal to the control device after detecting the core stack 148, and the control device controls the belt driving device 167 to stop operating after receiving the detection signal for a preset time. The above structure can prevent the core stack 148 from falling from the blanking end of the core stack conveyor 163.

Preferably, a baffle is further provided at the blanking end of the stack conveyor 163, which is configured to prevent the stack 148 from falling off the blanking end of the stack conveyor 163 in the event of a failure of the second sensor 165.

As shown in fig. 1 and 24, in the present embodiment, the flow line 157 further includes a third sensor 166 located at a blanking end of the core stack conveyor 163 and at a side of the second sensor 165 remote from the first sensor 164, and the core processing system further includes: the transferring mechanical arm and the third sensor 166 are electrically connected with the control device. Specifically, when the third sensor 166 detects the core segment stack 148, the third sensor 166 sends an in-position signal to the control device, and the control device controls the transfer robot to operate to transfer the core segment stack 148 into the core assembly machine 156. The structure enables the transferring mechanical arm to accurately clamp the iron core sheet stack 148, and the occurrence of empty clamping and clamping stagnation is avoided.

In this embodiment, the control device includes a first PLC controller, a second PLC controller, and a third PLC controller, the material collecting and stacking machine 155 is electrically connected to the first PLC controller, the iron core clamping and transferring machine 74, the adhesive tape bundling machine 72, and the iron core bundling and transferring machine 97 are electrically connected to the second PLC controller, and the flow line 157, the transfer robot, and the iron core assembling machine 156 are electrically connected to the third PLC controller. The structure enables the whole iron core processing system to be controlled in a classified mode, so that subsequent maintenance is facilitated.

As shown in fig. 1, in the present embodiment, the core assembling machines 156 are two that are symmetrically disposed at both sides of the flow line 157. Specifically, after the transfer robot arm has placed a sufficient number of core stack 148 on one of the core assembly machines 156, the transfer robot arm can continue to feed the core stack 148 to the other core assembly machine 156. Thus, while the worker assembles the iron cores on the previous iron core assembling machine 156, the other iron core assembling machine 156 also performs the preliminary work, thereby saving the assembling time and improving the overall assembling efficiency.

As shown in fig. 1, in the present embodiment, the material collecting and stacking machine 155 further includes a sheet conveyor 32, and the iron core processing system further includes: the punch 161 and the sheet conveyor 32 extend from the punch 161 toward the feed opening of the bin 3. The above structure can punch the long iron sheet 158 into a segment of core sheet.

As shown in fig. 1, in the present embodiment, the iron core processing system further includes: a flattener 160, the flattener 160 being located on a side of the punch 161 remote from the material receiving stacker 155. The above structure enables the iron sheet 158 to be flattened, thereby facilitating the subsequent stamping step.

As shown in fig. 1, in the present embodiment, the iron core processing system further includes: the iron sheet roll 159 is positioned on the side of the flattening machine 160 far away from the punching machine 161, and the iron sheet 158 on the iron sheet roll 159 extends into the flattening machine 160. The above structure can shorten the space occupied by the raw material, and as the iron sheet roll 159 rotates, the iron sheet 158 continuously enters the punch 161 to be punched, so as to obtain continuous iron core sheets.

As shown in fig. 2, 3 and 8, the material collecting and bundling system of the present embodiment includes: a material receiving and stacking machine 155, a rubber strip bundling machine 72 and an iron core clamping and transferring machine 74. Wherein, a supporting surface 11 for supporting the core sheet is arranged in the stock bin 3. The glue bundler 72 has a receiving hole 73 for receiving a structure to be bundled. The core clamping transfer machine 74 includes a first clamping structure 75 and a first moving structure 83, the first clamping structure 75 has a clamping state and a releasing state, the first moving structure 83 drives the first clamping structure 75 to move between the material receiving position and the first bundling position, the first clamping structure 75 can clamp the stack of core sheets on the supporting surface 11 when the first clamping structure 75 is at the material receiving position, and the stack of core sheets clamped by the first clamping structure 75 is located in the accommodating hole 73 when the first clamping structure 75 is at the first bundling position.

By using the technical scheme of the embodiment, during assembly, a piece of core sheet is collected in the storage bin 3 by the material collecting and stacking machine 155, and is collected into a stack, and then the core sheet stack in the storage bin 3 is clamped by the core clamping and transferring machine 74. Subsequently, the core clamping transfer machine 74 transfers the core stack to the accommodating hole 73 of the adhesive tape binding machine 72, and the core stack is bound by the adhesive tape binding machine 72. The receiving and bundling system enables the stacking and bundling of the core sheets mentioned in the background technology to be completed through a machine, so that the production efficiency of the core sheet stack is high, and finished products are more neat.

The above structure enables the bundled stack of core sheets to be transferred to a predetermined position, thereby facilitating the next assembly. In addition, it should be noted that the structure enables the iron core sheet stack to be transferred through a machine without manual transfer, so that the labor intensity of installation personnel is reduced, and the labor cost is saved.

In this embodiment, receive material bundling system still includes: the control device controls the first moving mechanism 83 and the second moving mechanism 106 to operate, and controls the first clamping mechanism 75 and the second clamping mechanism 98 to switch between the clamping state and the unclamping state. Specifically, when the core sheet stack is packed, the core sheet stack is clamped by the core clamping transfer machine 74, and then the core sheet stack is moved to the adhesive tape binding machine 72 by the core clamping transfer machine 74 to be bound for the first time. After the bundling is finished, the iron core bundling transshipment machine 97 is made to clamp the iron core sheet stack, the iron core clamping transshipment machine 74 is made to loosen, and after the iron core bundling transshipment machine 97 moves the iron core sheet stack to the preset position, the iron core sheet stack is bundled for the second time through the adhesive tape bundling machine 72. Above-mentioned structure makes the lamination pile have a plurality of bundle positions in the axial direction o of holding hole 73 to guarantee that the lamination pile is not scattered, thereby guarantee the bundle quality that the lamination pile. In addition, the structure is controlled by the control device, so that full automation of bundling of the iron core sheet stack is realized, and bundling efficiency is improved.

As shown in fig. 2, in the present embodiment, the core clamping transfer machine 74 and the core binding transfer machine 97 are located on opposite sides of the housing hole 73. The structure enables the iron core clamping and transferring machine 74 and the iron core bundling and transferring machine 97 to be more reasonable in spatial arrangement and not to interfere with each other in the working process.

By applying the technical scheme of the embodiment, when a plurality of core sheet stacking units need to be spliced, the plurality of core sheet stacking units are placed on the mounting platform 126 at intervals along the axial direction o, and then the second positioning piece is moved, so that the second positioning surface of the second positioning piece is in contact with one second side surface of the core sheet stacking unit; moving the first positioning piece to enable a first positioning surface of the first positioning piece to be in contact with one first side surface of the core sheet stack unit; after the first positioning piece and the second positioning piece move in place, the first jacking piece moves towards the first positioning piece to eliminate a gap between two adjacent iron core sheet stacking units, the second jacking piece moves towards the second positioning piece, and the second jacking face is abutted against the other second side face to enable the second side faces of the two adjacent iron core sheet stacking units to be parallel and level. The top and bottom surfaces of the plurality of core segment stacking units are substantially flush due to gravity. In this way, the core assembling machine 156 makes each surface of the rectangular parallelepiped formed by pre-assembling the plurality of core segment stack units flat. Finally, a proper amount of glue is dripped into the splicing position of the plurality of core sheet stacking units, so that the plurality of core sheet stacking units form a complete iron core. The iron core assembled by the iron core assembling machine 156 has flat surfaces and high assembling efficiency, and solves the problems of poor surface uniformity of the iron core and low iron core assembling efficiency caused by manual iron core assembling in the prior art.

The structure is simple and the cost is low. Of course, in other embodiments, the second jacking assembly may include a positioning hydraulic cylinder and a hold-down hydraulic cylinder. Or the positioning piece and the tightening piece are realized in a mode that a motor drives a screw rod to rotate, the screw rod drives a nut to move, and the nut is connected with a positioning plate or a pressing plate.

Because the iron cores have different models, the lengths of the iron cores of different models in the axial direction o are different. Under the condition that the length of the iron core is short, if one compression cylinder is adopted (the compression cylinder needs to be matched with the iron cores with different lengths, so that the length of a compression plate of the compression cylinder is long, and the distance between two expansion rods connected with the compression plate is large), only one expansion rod is possibly opposite to the second side surface of the iron core, so that the stress on the second side surfaces of a plurality of iron core sheet stacking units is uneven during compression, and the uniformity of the iron core is influenced. In order to solve the above problem, as shown in fig. 26, 27, and 29, in the present embodiment, the second pressing cylinders 138 are plural in number arranged at intervals in the axial direction o. The structure can ensure the stress uniformity of the second side surfaces of the plurality of iron core sheet stacking units of iron cores of different types, thereby ensuring the uniformity of the iron cores and improving the universality of the iron core assembling machine 156.

When glue is dripped to the splicing position of the plurality of core sheet stacking units, the glue is actually dripped on the upper surface of the iron core, and the glue seeps downwards under the self gravity to permeate into the splicing seams of the two adjacent core sheet stacking units. In order to make the penetration of the glue more sufficient, as shown in fig. 26, 28 and 29, in this embodiment, the second base frame 125 includes a frame body 141 and a mounting frame 142 rotatably disposed on the frame body 141, the mounting frame 142 includes two first mounting sides 143 oppositely disposed in the axial direction o, the first positioning cylinder 128 is disposed on one of the first mounting sides 143, the first pressing cylinder 131 is disposed on the other first mounting side 143, and an avoiding opening 145 for avoiding a telescopic rod of the first pressing cylinder 131 is disposed on the other first mounting side 143, a limiting seat 149 having a limiting hole is disposed on the frame body 141, the first pressing cylinder 131 is disposed in the limiting hole, and the iron core assembling machine 156 further includes: the overturning motor 146 is arranged on the frame body 141 and is in driving connection with the mounting frame 142, and a motor shaft of the overturning motor 146 is coaxial with an axis of the telescopic rod of the first pressing cylinder 131. Specifically, when the glue is dropped, the glue is dropped on the upper surface of the iron core, and after the glue is dropped, the iron core is turned over by the turning motor 146, so that the lower surface of the original iron core is turned over to form a new upper surface. And then the glue is dropped on the upper surface of the newly formed iron core. The structure can be used for dripping glue on the upper surface and the lower surface of the iron core, so that the iron core is bonded more firmly.

When the mounting frame 142 is flipped, the mounting frame 142 may interfere with the mounting platform 126, so that the mounting frame 142 may not be flipped smoothly. In order to solve the above problem, as shown in fig. 26, in the present embodiment, the core assembly machine 156 further includes: and the platform driving device 147 is in driving connection with the mounting platform 126 to drive the mounting platform 126 to ascend and descend, the mounting platform 126 is provided with a working position and an avoiding position located below the working position, and under the condition that the mounting platform 126 is located at the avoiding position, the mounting platform 126 does not interfere with the mounting frame 142. Specifically, before placing the plurality of core segment stacking units, the mounting platform 126 is raised to the working position by the platform driving device 147, and then the core segment stacking units are placed on the mounting platform 126 by the robot. And the mounting platform 126 is lowered to the retracted position by the platform drive 147 prior to inverting the mounting frame 142. After the mounting platform 126 is lowered in place, the mounting frame 142 is turned over to ensure that the mounting frame 142 is turned over smoothly.

As shown in fig. 26, in the present embodiment, the stage driving device 147 is a lift cylinder. The structure is simple and the cost is low.

Specifically, the above structure enables the first tightening assembly 127 and the second tightening assembly 134 to clamp the iron core when the mounting frame 142 is turned over, so as to ensure the alignment of the iron core before the second glue dripping and ensure the final product quality.

As shown in fig. 26 and 29, in the present embodiment, the axis of the telescopic rod of the first positioning cylinder 128 is coaxial with the axis of the telescopic rod of the first pressing cylinder 131. The structure enables the stress of the iron core to be more uniform, and the neatness of the iron core before bonding is ensured.
