[0002] The transformer iron core is the core component of the transformer, playing a key role in magnetic circuit guiding and energy transfer, and its performance directly affects the efficiency, loss and temperature rise of the transformer. The iron core stacking device in transformer manufacturing is a key equipment to ensure the lamination accuracy, efficiency and quality of the iron core, and its design needs to comprehensively consider material characteristics, process requirements and automation level. The iron core stacking device for transformer manufacturing usually consists of a feeding system, a positioning system and a stacking system, and the existing iron core stacking devices usually cannot achieve efficient and fully automatic iron core positioning and stacking, with low automation level. Summary of the Invention

The feeding mechanism includes a sliding frame fixedly installed on the upper frame. A lifting feeding box is slidably installed on the sliding frame. Two rows of convex platforms are arranged on the lifting feeding box, on which several iron cores are respectively placed. The iron cores are clamped on the convex platforms of the lifting feeding box by a pushing plate slidably installed on the lifting feeding box. The transfer mechanism includes a vertical plate, on which a rotating shaft is rotatably installed, and a suction and release module is arranged on the vertical plate.

An external pushing plate is slidably installed on the external feeding box. An external spring is arranged between the external pushing plate and the external feeding box. The external pushing plate clamps several iron cores on the retaining platform of the external feeding box. A pushing spring is arranged between the pushing plate and the lifting feeding box.

[0005] Further, a slider is slidably installed on the upper frame. A lifting lever is rotatably installed on the slider. The lifting lever is rotatably installed with the lifting feeding box. A track wheel is rotatably installed on the upper frame. A guide post is fixedly installed below the slider. An arc-shaped track groove is arranged on the track wheel. The guide post slides in the arc-shaped track groove of the track wheel. A docking wheel is rotatably installed on the upper frame. The rotating shaft drives the docking wheel to rotate through a belt drive. The docking wheel drives the track wheel to rotate through a gear drive.

[0006] Further, a turntable motor is fixedly installed on the bottom plate. A placing disk is fixedly installed on the motor shaft of the turntable motor. Several placing columns matching with the iron cores are arranged on the placing disk.

[0007] The docking wheel rotates, drives the track wheel to rotate through gear transmission, and then, through the cooperation between the arc-shaped track groove on the track wheel and the guide post, drives the slider to slide reciprocally along the upper frame. Thus, the lifting feed box is driven to lift along the sliding frame by jacking up the rotating rod. There are two rows of iron cores placed in the lifting feed box, and one row of iron cores is placed in the outer feed box. The turntable motor drives the placing disc to rotate, and each time the turntable motor drives the placing disc to rotate by 90 degrees.

[0008] Further, the transfer mechanism further includes a driving rod rotatably installed on the vertical plate. A long rotating rod is rotatably installed on the driving rod. A connecting rotating rod, an upper outer rod, an upper inner rod and an inclined rod are rotatably installed on the vertical plate. An output rod is rotatably installed on the long rotating rod. The inclined rod is rotatably installed with the long rotating rod. The output rod is rotatably installed with the connecting rotating rod. An outer rod and an inner rod are rotatably installed on the output rod. The inner rod is rotatably installed with the upper outer rod. The upper outer rod is rotatably installed with the upper inner rod. The upper inner rod is rotatably installed with the inclined rod. The outer rod is rotatably installed with the upper inner rod. The inner rod is rotatably installed with the connecting rotating rod. A lower outer rod is rotatably installed on the inner rod. The lower outer rod is rotatably installed with the upper outer rod. A lower inner rod is rotatably installed on the upper inner rod. The lower inner rod is rotatably installed with the outer rod. The lower outer rod is rotatably installed with the lower inner rod. A fixed column is fixedly installed on the lower inner rod.

[0009] Further, three suction cups are fixedly installed on the fixed column. The material taking motor is fixedly installed on the upper frame. A motor wheel is fixedly installed on the motor shaft of the material taking motor. The motor wheel drives the rotating shaft to rotate through belt transmission, and the rotating shaft drives the driving rod to rotate through belt transmission.

[0010] Further, the suction and release module includes a rotating arc block fixedly installed on the rotating shaft. An air shell is fixedly installed on the vertical plate. An air inlet and a suction port are arranged on the air shell, and the suction port is communicated with the suction cup.

[0011] The material taking motor drives the motor wheel to rotate. The motor wheel drives the rotating shaft, the driving rod, and the docking wheel to rotate through the transmission belt. The driving rod drives the long rotating rod to rotate. The long rotating rod drives the inclined rod to swing around the vertical plate. The long rotating rod drives the connecting rotating rod to swing around the vertical plate through the output rod. The connecting rotating rod drives the inner rod and the outer rod to rotate. The inclined rod rotates around the vertical plate, thereby driving the upper outer rod and the upper inner rod to rotate. The outer rod drives the lower outer rod and the lower inner rod to rotate. The upper inner rod and the lower outer rod always remain parallel, and the upper outer rod and the lower inner rod always remain parallel, thereby driving the fixed column and the suction cup to move to the iron core located at the lower layer of the lifting and feeding box. At this time, the arc-shaped rotating block blocks the air inlet, and the iron core is adsorbed through the suction cup. The iron core is taken out from the lifting and feeding box. When taking out, the iron core will undergo a small deformation to disengage from the convex platform of the lifting and feeding box. Then, the iron core is driven to move to the placement plate. At this time, the arc-shaped rotating block makes the air inlet communicate with the suction port, and at this time, the suction cup loses suction, and the iron core is placed on the placement column of the placement plate. This process is repeated. Every time the transfer mechanism places an iron core on the placement column of the placement plate, the placement plate rotates 90 degrees. After the transfer mechanism takes one iron core, the lifting and feeding box descends once. The next time, the transfer mechanism takes the iron core in the upper layer of the lifting and feeding box, and then the lifting and feeding box rises once, realizing the taking of the iron cores in the two layers of the lifting and feeding box, and this process is repeated in sequence.

[0012] Further, the secondary transfer mechanism includes an extending plate fixedly installed on the vertical plate. Two track frames are fixedly installed on the extending plate. A sliding block is slidably installed on the track frame. A lower rotating column is rotatably installed in the sliding block. A sliding block gear is fixedly installed on the lower rotating column. A lower motor is fixedly installed on the sliding block. The motor shaft of the lower motor is fixedly installed with the lower rotating column. A fixed rack is fixedly installed on the track frame. The fixed rack meshes with the sliding block gear. An electric suction cup is fixedly installed on the lower rotating column.

[0013] When the transfer mechanism takes the iron core in the lifting and feeding box, the lower motor drives the lower rotating column, the electric suction cup, and the sliding block gear to rotate. The cooperation between the sliding block gear and the fixed rack makes the sliding block slide along the track frame. When the electric suction cup reaches the outermost iron core in the outer feeding box, the electric suction cup adsorbs the iron core. When taking out, the iron core will undergo a small deformation to disengage from the retaining platform of the outer feeding box. Then, the lower motor drives the sliding block to descend, so that the electric suction cup reaches above the placement column of the placement plate, and the iron core is placed on the placement column of the placement plate. The placement plate rotates 90 degrees each time a placement is made.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: (1) The feeding mechanism provided by the present invention can achieve simultaneous feeding of multiple groups of iron cores, and automatically clamp the iron cores that have not been stacked, so as to achieve efficient and stable iron core stacking operation; (2) The transfer mechanism, sub-transfer mechanism and feeding mechanism provided by the present invention cooperate to realize the automatic placement of two rows of iron cores on the placement plate provided with placement columns one after another, realizing fully automatic iron core stacking, with high automation degree and good continuity; (3) The transfer mechanism provided by the present invention realizes continuous iron core stacking operation by continuously rotating the picking motor through a specific link mechanism, and the control system is simple and highly reliable.

[0028] As Figure 3 , Figure 4 shown, the feeding mechanism further includes an external feeding box 102 arranged beside the bottom plate 101.

The guide post 115 slides in the arc-shaped track groove of the track wheel 113. A docking wheel 112 is rotatably mounted on the upper frame 111. The rotating shaft 203 drives the docking wheel 112 to rotate through a belt drive. The docking wheel 112 drives the track wheel 113 to rotate through a gear drive.

[0030] As Figure 3 , Figure 4 As shown in Figure 4 , a turntable motor 107 is fixedly mounted on the bottom plate 101. A placing plate 108 is fixedly mounted on the motor shaft of the turntable motor 107. A number of placing posts for cooperating with the iron core 4 are provided on the placing plate 108.

[0031] The docking wheel 112 rotates to drive the track wheel 113 to rotate through a gear drive. Thus, through the cooperation of the arc-shaped track groove on the track wheel 113 and the guide post 115, the slider 114 is driven to reciprocally slide along the upper frame 111. Thereby, the lifting and feeding box 104 is driven to lift and lower along the sliding frame 103 through the lifting lever 116. Two upper and lower rows of iron cores 4 are placed in the lifting and feeding box 104, and one row of iron cores 4 is placed in the outer feeding box 102. The turntable motor 107 drives the placing plate 108 to rotate, and the turntable motor 107 drives the placing plate 108 to rotate 90 degrees each time.

[0032] As Figures 5 - 9 As shown in Figures 5 - 9 , the transfer mechanism further includes a driving rod 209 rotatably mounted on the vertical plate 208. A long lever 210 is rotatably mounted on the driving rod 209. A connecting lever 213, an upper outer lever 221, an upper inner lever 216, and an inclined lever 212 are rotatably mounted on the vertical plate 208. An output rod 211 is rotatably mounted on the long lever 210. The inclined lever 212 is rotatably mounted with the long lever 210. The output rod 211 is rotatably mounted with the connecting lever 213. An outer rod 214 and an inner rod 215 are rotatably mounted on the output rod 211. The inner rod 215 is rotatably mounted with the upper outer lever 221. The upper outer lever 221 is rotatably mounted with the upper inner lever 216. The upper inner lever 216 is rotatably mounted with the inclined lever 212. The outer rod 214 is rotatably mounted with the upper inner lever 216. The inner rod 215 is rotatably mounted with the connecting lever 213. A lower outer rod 217 is rotatably mounted on the inner rod 215. The lower outer rod 217 is rotatably mounted with the upper outer lever 221. A lower inner rod 218 is rotatably mounted on the upper inner lever 216. The lower inner rod 218 is rotatably mounted with the outer rod 214. The lower outer rod 217 is rotatably mounted with the lower inner rod 218. A fixed post 219 is fixedly mounted on the lower inner rod 218.

[0033] As Figures 5 - 9As shown in the figure, three suction cups 220 are fixedly installed on the fixed column 219. The material taking motor 201 is fixedly installed on the upper frame 111. A motor wheel 202 is fixedly installed on the motor shaft of the material taking motor 201. The motor wheel 202 drives the rotating shaft 203 to rotate through belt transmission, and the rotating shaft 203 drives the driving rod 209 to rotate through belt transmission.

[0034] As Figures 5 - 9 shown in the figure, the suction and release module includes a rotating arc block 204 fixedly installed on the rotating shaft 203. A gas shell 205 is fixedly installed on the vertical plate 208. An air inlet 206 and a suction port 207 are arranged on the gas shell 205. The suction port 207 is communicated with the suction cup 220.

[0035] The material taking motor 201 drives the motor wheel 202 to rotate. The motor wheel 202 drives the rotating shaft 203, the driving rod 209 and the docking wheel 112 to rotate through the transmission belt. The driving rod 209 drives the long rotating rod 210 to rotate. The long rotating rod 210 drives the inclined rod 212 to swing around the vertical plate 208. The long rotating rod 210 drives the connecting rotating rod 213 to swing around the vertical plate 208 through the output rod 211. The connecting rotating rod 213 drives the inner rod 215 and the outer rod 214 to rotate. The inclined rod 212 rotates around the vertical plate 208, thereby driving the upper outer rod 221 and the upper inner rod 216 to rotate. The outer rod 214 drives the lower outer rod 217 and the lower inner rod 218 to rotate. The upper inner rod 216 and the lower outer rod 217 always remain parallel. The upper outer rod 221 and the lower inner rod 218 always remain parallel. Thereby driving the fixed column 219 and the suction cup 220 to move to the iron core 4 located at the lower layer of the lifting and feeding box 104. At this time, the rotating arc block 204 blocks the air inlet 206, and the iron core 4 is adsorbed through the suction cup 220. The iron core 4 is taken out from the lifting and feeding box 104. When taking out, the iron core 4 will have a small deformation to break away from the convex platform of the lifting and feeding box 104. Then drive the iron core 4 to move to the placing plate 108. At this time, the rotating arc block 204 makes the air inlet 206 communicate with the suction port 207. At this time, the suction cup 220 loses suction, and the iron core 4 is placed on the placing column of the placing plate 108. And so on. Every time the transfer mechanism places an iron core 4 on the placing column of the placing plate 108, the placing plate 108 rotates 90 degrees. After the transfer mechanism takes it once, the lifting and feeding box 104 descends once. Next time the transfer mechanism takes the iron core 4 on the upper layer of the lifting and feeding box 104, and then the lifting and feeding box 104 rises once, realizing the taking of the iron cores 4 on the two layers of the lifting and feeding box 104, and so on in turn.

[0036] As Figure 10As shown, the secondary rotation mechanism includes an extension plate 301 fixedly installed on the vertical plate 208. Two track frames 302 are fixedly installed on the extension plate 301. A sliding block 304 is slidably installed on the track frame 302. A lower rotation column 306 is rotatably installed in the sliding block 304. A slider gear 305 is fixedly installed on the lower rotation column 306. A lower motor 308 is fixedly installed on the sliding block 304. The motor shaft of the lower motor 308 is fixedly installed with the lower rotation column 306. A fixed rack 303 is fixedly installed on the track frame 302. The fixed rack 303 meshes with the slider gear 305. An electric suction cup 307 is fixedly installed on the lower rotation column 306.

[0037] When the transfer mechanism picks up the iron core 4 in the lifting and feeding box 104, the lower motor 308 drives the lower rotation column 306, the electric suction cup 307 and the slider gear 305 to rotate. The cooperation between the slider gear 305 and the fixed rack 303 causes the sliding block 304 to slide along the track frame 302. When the electric suction cup 307 reaches the outermost iron core 4 in the outer feeding box 102, the electric suction cup 307 adsorbs the iron core 4. When taking out, the iron core 4 will have a small deformation to break away from the retaining platform of the outer feeding box 102. Subsequently, the lower motor 308 drives the sliding block 304 to descend, so that the electric suction cup 307 reaches above the placement column of the placement plate 108, and the iron core 4 is placed on the placement column of the placement plate 108. The placement plate 108 rotates 90 degrees for each placement.

[0038] The working principle of a core stacking device for transformer manufacturing disclosed by the present invention is as follows: The feeding motor 201 drives the motor wheel 202 to rotate. The motor wheel 202 drives the rotating shaft 203, the driving rod 209, and the docking wheel 112 to rotate through a transmission belt. The rotation of the docking wheel 112 drives the track wheel 113 to rotate through gear transmission. Thus, through the cooperation of the arc-shaped track groove on the track wheel 113 and the guide post 115, the slider 114 is driven to slide reciprocally along the upper frame 111. Thereby, the lifting feeding box 104 is driven to lift along the sliding frame 103 through the jacking lever 116. There are two rows of cores 4 placed in the lifting feeding box 104, and one row of cores 4 is placed in the external feeding box 102. The turntable motor 107 drives the placement plate 108 to rotate. Each time the turntable motor 107 drives the placement plate 108 to rotate by 90 degrees. The feeding motor 201 drives the motor wheel 202 to rotate. The motor wheel 202 drives the rotating shaft 203, the driving rod 209, and the docking wheel 112 to rotate through a transmission belt. The driving rod 209 drives the long lever 210 to rotate. The long lever 210 drives the inclined rod 212 to swing around the vertical plate 208. The long lever 210 drives the connecting lever 213 to swing around the vertical plate 208 through the output rod 211. The connecting lever 213 drives the inner rod 215 and the outer rod 214 to rotate. The inclined rod 212 rotates around the vertical plate 208, thereby driving the upper outer rod 221 and the upper inner rod 216 to rotate. The outer rod 214 drives the lower outer rod 217 and the lower inner rod 218 to rotate. The upper inner rod 216 and the lower outer rod 217 always remain parallel. The upper outer rod 221 and the lower inner rod 218 always remain parallel. Thus, the fixed column 219 and the suction cup 220 are driven to move to the position of the core 4 in the lower layer of the lifting feeding box 104. At this time, the rotating arc block 204 blocks the air inlet 206, and the core 4 is adsorbed by the suction cup 220. The core 4 is taken out from the lifting feeding box 104. When taking out, the core 4 will undergo a small deformation to disengage from the boss of the lifting feeding box 104. Subsequently, the core 4 is driven to move onto the placement column of the placement plate 108. At this time, the rotating arc block 204 makes the air inlet 206 communicate with the suction port 207. At this time, the suction cup 220 loses suction, and the core 4 is placed on the placement column of the placement plate 108. This process is repeated. Each time the transfer mechanism places a core 4 on the placement column of the placement plate 108, the placement plate 108 rotates by 90 degrees. After the transfer mechanism takes one core 4, the lifting feeding box 104 descends once. Next, the transfer mechanism takes the core 4 in the upper layer of the lifting feeding box 104, and then the lifting feeding box 104 rises once, realizing the taking of the two layers of cores 4 in the lifting feeding box 104, and this process is repeated in sequence.When the transfer mechanism picks up the iron core 4 in the lifting and feeding box 104, the lower motor 308 drives the lower rotating column 306, the electric suction cup 307 and the slider gear 305 to rotate. The cooperation between the slider gear 305 and the fixed rack 303 causes the slider 304 to slide along the track frame 302. When the electric suction cup 307 reaches the outermost iron core 4 in the outer feeding box 102, the electric suction cup 307 adsorbs the iron core 4. When taking out, the iron core 4 will have a small deformation to break away from the retaining platform of the outer feeding box 102. Subsequently, the lower motor 308 drives the slider 304 to descend, so that the electric suction cup 307 reaches above the placing column of the placing disk 108, and places the iron core 4 on the placing column of the placing disk 108. Each time a placement is made, the placing disk 108 rotates 90 degrees.
