[0068] The disk support jaw 236 is driven by the jaw cylinder 1 235 to clamp the disk support 802 in the disk support positioning hole 233. At the same time, the linear slide C31 drives the slide C32 to drive the screw driving mechanism 1 33 to move to the screw feeder A10. The lifting plate 1 332 is driven to descend by the telescopic cylinder A331. The M1.6*5 countersunk head screw 1 803 provided by the screw feeder A10 is adsorbed by the screw suction nozzle 338. Then, the M1.6*5 countersunk head screw 1 803 is driven by the linear slide C31 and the telescopic cylinder A331 to dip glue and then move it above the circuit board 1 801. The electric screwdriver 333 and the screw suction nozzle 338 are driven to descend by the telescopic cylinder A331. The spring 1 334 plays a buffering role in the pressing impact between the suction nozzle connecting plate 336 and the circuit board 1 801. The M1.6*5 countersunk head screw 1 803 is screwed by the screwdriver bit of the electric screwdriver 333 to drive the screw, thus completing the assembly of the disk support 802 and the circuit board 1 801. At the same time, the vibrating bowl 121 conveys the copper support 1 804 to the linear rail 122 one by one. The copper support 1 804 is conveyed to the positioning fixture 125. The single copper support 1 804 is lifted by the telescopic cylinder K124. At this time, the linear slide C31 drives the slide C32 to drive the copper support clamping mechanism 35 to move to the lifted copper support 1 804. The finger cylinder 1 353 clamps the copper support 1 804 through the rotary cylinder 1 351 and the telescopic cylinder B352, and the copper support 1 804 is placed in the copper support positioning hole 251 through the linear slide C31, the rotary cylinder 1 351, the telescopic cylinder B352 and the finger cylinder 1 353. At the same time, the drive motor 1 26 drives the rotary bracket 24 and the motor positioning disk 25 to rotate, and multiple copper supports 1 804 are placed in the copper support positioning holes 251 in turn according to the above method. Then, the linear slide B21 and the linear slide A101 drive the slides B22 and A102 to move horizontally toward the middle side transverse movement mechanism 4 respectively. The nut feeder 11 supplies the M1.6 nut 1 806. The finger cylinder 2 422 clamps the M1.6 nut 1 806 and places it in the nut positioning hole 254 through the cooperation of the linear slide D41 and the telescopic cylinder C421. The finger cylinder 3 432 clamps the single stepper motor 1 805 on the motor feeding disk 103 and places the stepper motor 1 805 in the motor positioning groove 253 through the cooperation of the linear slide D41 and the telescopic cylinder D431. At this time, the linear slide B21 drives the slide B22 to move toward the circuit board flipping mechanism 6, while the motor feeding disk 103 stays here to prepare for the motor assembly at the other assembly station.

[0069] When the slide block B22 moves to the circuit board flipping mechanism 6, the linear drive mechanism 62 drives the slide plate 63 and the circuit board gripper 68 to move towards the circuit board 801. The circuit board gripper 68 is driven by the gripper cylinder 67 to grip the circuit board 801. The telescopic cylinder G64 extends to push the lifting plate 65 to raise the circuit board 801, and the rotary cylinder 66 drives the circuit board 801 to flip. The linear slide B21 drives the rotary bracket 24 to move to the directly below of the circuit board 801. The telescopic cylinder G64 contracts to place the circuit board 801 on the positioning table 252, and the circuit board flipping mechanism 6 returns to the original position. The linear slide B21 drives the slide block B22 to move towards the rear side transverse movement mechanism 5. The screw feeder B14 and the screw feeder C15 supply the M1.6*12 pan head screws 807 and the M3 pan head screws 808 respectively. The linear slide E51 drives the screw driving mechanism 56 and the screw driving mechanism 57 to move horizontally. The screw driving mechanism 56 and the screw driving mechanism 57 respectively pick up the M1.6*12 pan head screws 807 and the M3 pan head screws 808, and the screw driving mechanism 56 dips the M1.6*12 pan head screws 807 with glue and then screws them through the mounting holes of the circuit board 801, the stepping motor 805 and the M1.6 nut 806 to complete the assembly of the circuit board 801 and the stepping motor 805. The screw driving mechanism 57 dips the M3 pan head screws 808 with glue and then screws them through the assembly hole 809 and fixedly connects them with the internal thread of the copper pillar 804 to complete the assembly of the copper pillar 804 and the circuit board 801. The disc pillar feeder 17 supplies the disc pillars 802.

[0070] The linear slide B21 drives the slide B22 to move towards the circuit board welding mechanism 7. The linear slide F71 drives the welding head assembly 76 to move above the first circuit board 801. The second linear drive mechanism 73 drives the welding head assembly 76 to descend, and makes the welding head of the welding torch 764 close to the first circuit board 801. The drive motor three 745 drives the wire feeding wheel 743 to rotate, so that the welding wire in the wire storage cylinder 741 is released along the first wire guiding tube 746. The released welding wire falls on the welding head of the welding torch 764 after passing through the second wire guiding tube 768, thereby welding the power supply pins of the first stepping motor 805 to the first circuit board 801. The inclination angle of the second wire guiding tube 768 can be adjusted by the swing hinge rod 767. The inclination angle of the welding torch 764 can be adjusted by removing the connecting screws between the fourth lifting plate 75 and the adjusting plate 761. The spring two 765 plays a buffering role in the abutment between the welding torch 764 and the first circuit board 801. After welding is completed, the linear slide B21 drives the slide B22 to move to the initial position, and the assembled transparent disc circuit board assembly 800 is taken out manually. At the same time, the welding slag remaining on the welding torch 764 is blown into the cleaning box 771 through the air blowing nozzle 772. Thus, the assembly of one transparent disc circuit board assembly 800 is completed. Two sets of longitudinal movement and type-changing mechanisms 2 and two sets of circuit board flipping mechanisms 6 are symmetrically arranged on the support table 18. The longitudinal movement and type-changing mechanisms 2 on both sides perform cross feeding for assembly processing, improving the assembly efficiency of the circuit board assembly device.

At the same time, the copper pillar feeder 12 supplies the second copper pillar 904. The second copper pillar 904 is clamped by the copper pillar clamping mechanism 35 and placed in the copper pillar positioning hole 251. At the same time, the drive motor one 26 drives the rotating bracket 24 and the motor positioning disc 25 to rotate, and a plurality of second copper pillars 904 are sequentially placed in the copper pillar positioning holes 251 according to the above method. Then the linear slide B21 and the linear slide A101 drive the slide B22 and the slide A102 to move towards the middle-side transverse movement mechanism 4 respectively. The nut feeder 11 supplies the second M1.6 nut 906. The finger cylinder two 422 clamps the second M1.6 nut 906 and places it in the nut positioning hole 254 through the cooperation of the linear slide D41 and the telescopic cylinder C421. The stepping motor two 905 is clamped and placed in the motor positioning groove 253 through the cooperation of the linear slide D41 and the motor clamping mechanism 43. At this time, the linear slide B21 drives the slide B22 to move towards the circuit board flipping mechanism 6, while the motor material discharging disc 103 stays here to prepare for the motor assembly at the other assembly station.

[0072] When the slide seat B22 moves to the circuit board flipping mechanism 6, the linear drive mechanism 62 drives the slide plate 63 and the circuit board gripper 68 to move towards the circuit board 901. The circuit board gripper 68 is driven by the gripper cylinder 67 to grip the circuit board 901. The telescopic cylinder G64 extends to push the lifting plate 65 to raise the circuit board 901. The linear slide table B21 drives the rotating bracket 24 to move to directly below the circuit board 901. The telescopic cylinder G64 contracts to place the circuit board 901 on the positioning table 252, and the circuit board flipping mechanism 6 returns to its original position. The linear slide table B21 drives the rotating bracket 24 to move to the position of the middle lateral translation mechanism 4. The fixed ring pillar feeder 13 supplies the fixed ring pillars 907. The finger cylinder 448 grips the fixed ring pillar 907 and moves it to the position of the circuit board 901 through the cooperation of the linear slide table D41 and the telescopic cylinder E441. The telescopic cylinder E441 lowers the fixed ring pillar 907, and the drive motor 443 drives the finger cylinder 448 to rotate, so as to screw the fixed ring pillar 907 through the mounting holes of the circuit board 901, the stepping motor 905, and the M1.6 nut 906, completing the assembly of the circuit board 901 and the stepping motor 905.

[0073] The linear slide table B21 drives the slide seat B22 to move towards the rear lateral translation mechanism 5. The linear slide table G81 drives the slide seat G82 and the lifting block 821 to rise, pushing the stacked fixed rings 902 in the fixed ring stacking fixture 86 to rise. The suction cup 542 sucks up a single fixed ring 902 and places it in the fixed ring gripper 96 through the cooperation of the linear slide table E51 and the telescopic cylinder F541. The fixed ring clamping cylinder 95 drives the fixed ring gripper 96 to clamp the fixed ring 902. The telescopic cylinder I93 extends to push the slide plate 94 and the fixed ring 902 towards the circuit board 901 and places the fixed ring 902 on the fixed ring pillar 907. The visual camera detection mechanism 55 detects the placement of the fixed ring 902. The screw feeder C15 and the screw feeder D16 supply the M3 pan head screws 908 and the M1.6*4 pan head screws 903 respectively. The linear slide table E51 drives the screw driving mechanism 56 and the screw driving mechanism 57 to move horizontally. The screw driving mechanism 56 and the screw driving mechanism 57 respectively suck up the M1.6*4 pan head screws 903 and the M3 pan head screws 908, and the screw driving mechanism 56 dips the M1.6*4 pan head screws 903 with glue and screws them through the fixed ring 902 and then fixedly connects them with the internal thread of the fixed ring pillar 907, completing the assembly of the fixed ring 902 and the fixed ring pillar 907. The screw driving mechanism 57 dips the M3 pan head screws 908 with glue and screws them through the assembly hole 909 and then fixedly connects them with the internal thread of the copper pillar 904, completing the assembly of the copper pillar 904 and the circuit board 901.

[0074] The linear slide B21 drives the slide B22 to move towards the circuit board welding mechanism 7, and the circuit board welding mechanism 7 welds the lead pins of the second stepping motor 905 to the second circuit board 901. Thus, the assembly of a luminous disk circuit board assembly 900 is completed; two sets of longitudinal movement and type-changing mechanisms 2, two sets of circuit board flipping mechanisms 6, and two sets of fixed ring feeding mechanisms 9 are symmetrically arranged on the support table 18. The two longitudinal movement and type-changing mechanisms 2 on both sides perform cross feeding for assembly processing, improving the assembly efficiency of the circuit board assembly device.
