The bottom end of the first negative pressure pipe 281 is sealed and penetrates to the bottom of the connecting seat 24 and is sealed and plugged with a four-way pipe 283. Both ends of the four-way pipe 283 are connected to the two second negative pressure pipes 282. The remaining end of the four-way pipe 283 is connected to the total negative pressure pipe 284.

The electric five-way valve 288 includes a valve 2882 installed on the top of a first servo motor 2881 fixedly connected to the top of the base 26. A valve plate 2883 in the valve 2882 separates the five pipe heads into three and two. The inlet and outlet ends of the air pump 287 are respectively connected to an exhaust pipe 289 and an exhaust pipe 285. The exhaust pipe 289, the total negative pressure pipe 284, the blowing pipe 286 and the exhaust pipe 285 are sequentially connected to four of the pipe heads of the valve 2882. The remaining pipe head of the valve 2882 is equipped with an air filter head. A convex ring 207 is provided at the bottom of the bottom cover 202 of the first positioning seat 21 corresponding to the point where the air pipe 286 passes through, and a positioning circular groove 241 adapted to the convex ring 207 is provided on the top of the connecting seat 24. A large through groove 242 is provided inside the connecting seat 24 corresponding to the point where the second negative pressure tube 282 passes through, and a U-shaped frame is fixedly connected to the bottom of the connecting seat 24 and located on one side of the large through groove 242, and a rotating drum 243 is rotatably sleeved on the U-shaped frame.

[0026] The air pump 287 draws air through the suction pipe 289 and exhausts air through the exhaust pipe 285. The suction pipe 289 draws air from the electric five-way valve 288, and then uses the total negative pressure pipe 284 to draw air from the four-way valve 283. Then, the first negative pressure pipe 281 and the second negative pressure pipe 282 draw air from the first positioning seat 21, the second positioning seat 22, and the third positioning seat 23 to adsorb the insulating substrate 3, the coil 4 and the magnetic core 5. After stacking, stop the air pump 287 to eliminate the suction force, and then control the second positioning seat 2 2 or the third positioning seat 23 rotates, and the air pump 287 is started again after it is fully rotated until the stacking is completed, and then the electric five-way valve 288 is controlled to switch, so that the exhaust pipe 289 is connected with the total negative pressure pipe 284 and the air filter head, thereby extracting most of the external air, making the suction force of the negative pressure hole 204 on the first positioning seat 21 small, and the exhaust pipe 285 is connected with the blowing pipe 286, and then a blowing force is generated from the blowing hole 205 to blow the parts to the left for collection, and then the subsequent welding of the metal wire 6 and assembly of the insulating shell 7 are carried out.

[0028] The feeding mechanism 1 comprises: The left ends of the three groups of loading racks 11 are respectively connected to the three groups of sinking positioning grooves 203, and the left ends of the three groups of loading racks 11 are fixed on the fixed tray 25; The bracket 12 is fixedly connected to the bottom of the loading rack 11 to support the three groups of loading racks 11 .

The surface of the insulating substrate 3 is coated with glue or adhered with double-sided tape.

[0030] The multiple pipelines of the air supply component 28 are connected and direction-controlled by the four-way valve 283 and the electric five-way valve 288, so that only one air pump 287 is needed to simultaneously realize the operations of negative pressure suction and blowing discharge, and the two do not interfere with each other. It is only necessary to control the switching and start and stop of the electric five-way valve 288, which is simple and convenient to control.

[0032] After the second servo motor 271 drives the small toothed pulley 272 to rotate, the gear belt 274 drives the large toothed pulley 273 to rotate, thereby driving the large toothed pulley 273 and the shifting rod 276 to rotate. The shifting rod 276 pushes the short shaft 275 to flip the second positioning seat 22 or the third positioning seat 23, thereby driving the parts thereon to flip and stack.

[0033] By driving the lever 276 to rotate via the second servo motor 271 , the second positioning seat 22 and the third positioning seat 23 can be flipped in sequence, which is simple and convenient to operate and has a high degree of automation.
