After the pre-assembly between the housing 51 and the two terminals is achieved, the rotating shaft of the rotating motor 12 continues to rotate, causing the rotating platform 14 to continue rotating. When the placement seat 141 with the coil 5 rotates below the second pressing cylinder 171, the rotating platform 14 stops rotating. The telescopic rod of the second pressing cylinder 171 extends until the pressing member 1512 presses the housing 51 onto the placement seat 141. Subsequently, the telescopic rod of the reinforcing cylinder 172 extends to push the terminals to achieve the complete assembly between the two terminals and the housing 51. In order to improve the qualified rate of the products formed by the assembly of the coil 5 during its discharging, the coil 5 is detected by the detection device 18. When the rotating platform 14 rotates to drive the placement seat 141 and the coil 5 to rotate in front of the detection device 18, the coil 5 in the placement seat 141 is detected to check whether two terminals are successfully installed in the housing 51. Additionally, the distance between the two terminals installed on the two housings 51 is then detected to determine whether the assembled coil 5 meets the qualified standard.

The surfaces of the respective feeding blocks 423 are each provided with a feeding groove 4231 for placing the coil 5.
[0078] When the rotating platform 14 rotates to drive the qualified coil 5 to rotate to the lower side of the first blanking manipulator 191, the first blanking manipulator 191 picks up the coil 5 in the placing seat 141. Subsequently, the rotating shaft of the driving motor 1932 rotates, and through the transmission between the driving screw rod 1933 and the driving nut seat 1934, the first blanking manipulator 191 is driven to move towards the direction close to the conveying table 42. When the first blanking manipulator 191 moves above the conveying table 42, the first blanking manipulator 191 places the qualified coil 5 into the feeding groove 4231 of the feeding block 423. Subsequently, the rotating shaft of the driving motor 1932 rotates in the reverse direction to drive the first blanking manipulator 191 to return above the placing seat 141 again, and so on to blank the next qualified coil 5; when an unqualified coil 5 appears, the terminal of the rotating platform 14 continues to rotate until it rotates to the lower side of the second blanking manipulator 192. Subsequently, the second blanking manipulator 192 takes out and blanks the unqualified coil 5 from the placing seat 141. When the twelve coils 5 are filled on the conveying table 42, the coils 5 can be conveyed to the winding device 2 through the conveying device 4.

[0080] After the twelve coils 5 placed on the feeding beam are transferred to the positions corresponding to the twelve expansion buckles 226 by the transfer device 4, the telescopic rod of the transfer cylinder 421 is extended to drive the feeding beam to move in the direction close to the winding device 2 until the twelve coils 5 on the feeding beam are sleeved on the periphery of the expansion buckle 226, and the telescopic rod of the fixed cylinder 224 is extended to drive the expansion rod 225 to completely penetrate into the expansion buckle 226, so that the expansion buckle 226 is tightly pressed against the inner wall of the coil 5 to install and fix the coil 5. In addition, an infrared sensor 2236 is fixedly provided on the lead frame 2231. The detector 2236 emits infrared light to detect whether the coil 5 is successfully installed on each expansion buckle 226; then the lead frame 2231 starts to rotate, flip and swing, so that the lead needle 2232 starts to wind the resistance wire 53 around the pin 52 of the coil 5 and the shell 51, and then the rotating shaft of the rotary motor 221 rotates to drive the coil 5 fixed on the expansion shell to rotate, so that the resistance wire 53 is wound around the periphery of the shell 51; the cutting device 23 includes two lifting cylinders 231, a cutting beam 232 and twelve cutting knives 233, and the two lifting cylinders 231 are fixedly arranged on the lead frame 2231.

After the twelve coils 5 on the winding device 2 are wound, the resistance wire 53 is wound on the streamline of the wire retaining seat 2234 through the lead needle 2232.

[0081] Reference Figure 27 、 Figure 28 and Figure 29, the rotating shaft of the conveying motor 43 continues to rotate, and through the transmission between the conveying screw rod 44 and the conveying nut seat 45, twelve coils 5 are conveyed to the welding device 3; the welding device 3 includes a conveying platform 31, a first soldering device 32, a second soldering device 33, a DCR testing device 34 and an AOI testing device 35. The conveying platform 31 is circular. The first soldering device 32, the second soldering device 33, the DCR testing device 34 and the AOI testing device 35 are arranged in sequence on the circumferential side of the conveying platform 31. A number of fixing rods 311 are arranged around the periphery of the conveying platform 31, and the number of fixing rods 311 are evenly distributed around the periphery of the conveying platform 31. When the coil 5 is conveyed to the soldering device by the conveying device 4, the telescopic rod of the conveying cylinder 421 extends to drive the coil 5 on the feeding block 423 to be sleeved around the periphery of the fixing rod 311 for installation and fixation. Subsequently, the coil 5 is conveyed to the first soldering device 32 under the action of the conveying platform 31. The first soldering device 32 solders and fixes one of the pins 52 of the coil 5 to the resistance wire 53 wound around the pin 52. The coil 5 is conveyed to the second soldering device 33 under the action of the conveying platform 31. The second soldering device 33 solders and fixes the other pin 52 of the coil 5 to the resistance wire 53 wound around the pin 52. The coil 5 continues to be conveyed to the DCR testing device 34 under the action of the conveying platform 31. The DCR testing device 34 can be selected as the TH2516B DC resistance tester. The AOI testing device 35 can be selected as the TH2882A-3 turn-to-turn insulation tester. The TH2882A-3 turn-to-turn insulation tester needs to test the electrical performance of the tested component without damaging it. The primary condition is to be able to judge the quality of the coil in a short moment. The resistance of the coil 5 is detected by the DCR testing device 34. Finally, the coil 5 is conveyed to the AOI testing device 35 under the action of the conveying platform 31. The turn-to-turn insulation of the coil 5 is detected by the AOI testing device 35 to judge whether the coil 5 meets the production standard. After the detection of the coil 5 is completed, the coil 5 can be unloaded.
[0082] Refer to Figure 30 , Figure 31 and Figure 32, the specific implementation principle of the embodiment of the present application is as follows: When the coil 5 needs to be produced, the housing 51 is fed by the housing vibrating disk 131 and the feeding manipulator 132. The feeding manipulator 132 places the housing 51 on the placing seat 141, and the rotating platform 14 rotates to convey the housing 51. When the housing 51 is conveyed to the pre-assembly device 16, the first pressing cylinder 1511 temporarily fixes the housing 51. The pin feeding component 132 feeds the pins 52. The pins 52 enter the transmission track 1332 under the vibration of the pin vibrating disk 1331, and are clamped in the installation groove 13321 of the transmission track 1332 under the action of the vibrating platform 1333, and are arranged along the length direction of the transmission track 1332. The support seat 1624 rises to the surface flush with the transmission track 1332 under the drive of the support power component 1621. The telescopic rod of the feeding power component 1334 extends to drive the lever 1335 to dial the pins into the support groove 16241 of the support seat 1624; the telescopic rod of the pressing power component 1631 extends to drive the pressing arm 1634 to cover the surface of the support seat 1624, so that the pins 52 are fixed between the support seat 1624 and the pressing arm 1634. The telescopic rod of the power component 1611 extends to drive the support component 162 and the pressing component 163 to move towards the fixed component 151, so as to insert the pin ends of the pins 52 into the housing 51, thereby completing the pre-assembly between the pins 52 and the housing 51; Subsequently, the support power component 1621 drives the support seat 1624 to descend, the pressing power component 1631 drives the pressing arm 1624 to move away from the fixed component 151, and the telescopic rod of the power component 1611 retracts to drive the support component 162 and the pressing component 163 to move towards the pin feeding component 133, so as to perform the next pin insertion process of the pins 52.
[0083] When the coil 5 is conveyed to the reinforcement cylinder 172, the second pressing cylinder 171 temporarily fixes the housing 51. The reinforcement cylinder 172 completes the actual assembly of the coil 5, and then the assembled coil 5 is detected by the detection device 18; Finally, the coil 5 is conveyed to the blanking device 19. The first blanking manipulator 191 blanks the coil 5 that has passed the detection. The rotating shaft of the driving motor 1932 rotates to drive the transmission between the driving screw 1933 and the driving nut seat 1934, so that the first blanking manipulator 191 conveys towards the conveying device 4, and the coil 5 that has passed the detection is blanked onto the feeding block 423 of the conveying device 4. Twelve coils 5 are arranged in a group on the feeding beam of the conveying device 4, and the second blanking manipulator 192 blanks the coils 5 that have not passed the detection.
[0084] The rotating shaft of the conveying motor 43 rotates to drive the conveying screw rod 44 to rotate. Under the action of the conveying screw rod 44, the conveying nut seat 45 drives the conveying table 42 to move towards the winding device 2. When the conveying table 42 moves to the position of the winding device 2, the telescopic rod of the conveying cylinder 421 extends to drive the conveying beam 422 to move towards the expansion rod 225, so that the coil 5 located on the feeding block 423 is sleeved around the expansion buckle 226. The telescopic rod of the fixing cylinder 224 extends to drive the expansion rod 225 to penetrate into the expansion buckle 226, so that the expansion buckle 226 is firmly clamped with the coil 5. The infrared sensor 2236 detects the installation of the coil 5. Each lead pin 2232 winds one end of the resistance wire 53 around the pin 52. The rotating shaft of the rotating motor 221 rotates, so that the resistance wire 53 is then wound around the surface of the housing 51. Subsequently, the resistance wire 53 is wound around the other pin 52 of the coil 5. Finally, the resistance wire 53 is wound around each wire-retaining rod 2235. The telescopic rod of the lifting cylinder 231 extends to drive the cutting scissors 233 to cut the resistance wire 53 between the pin 52 and the wire-retaining rod 2235. The telescopic rod of the conveying cylinder 421 continues to extend, driving the feeding beam to move towards the winding device 2 to unload the wound coil 5.
[0085] The conveying device 4 conveys the coil 5 to the welding device. Subsequently, the telescopic rod of the conveying cylinder 421 extends to drive the housing 51 to be sleeved on the fixing rod 311 outside the conveying platform 31. The conveying platform 31 starts to rotate to convey the coil 5 to the first soldering device 32 to solder one of the pins 52 and the resistance wire 53 wound around its periphery. The conveying platform 31 continues to rotate to convey the coil 5 to the second soldering device 33 to solder the other pin 52 and the resistance wire 53 wound around its periphery. Finally, the conveying platform 31 then rotates to detect the resistance of the coil 5 through the DCR testing device 34 and detect the inter-turn insulation of the coil 5 through the AOI testing device 35, so as to judge whether the coil 5 meets the production standard. After the detection is completed, the coil 5 can be unloaded.
