The working principle of the invention is as follows:

first, the system is started, the fixing seat 21 on the conveying line 90 is conveyed to the valve body clamping device 32 by the conveying line, the first lifting mechanism 322 drives the second manipulator 323 to move upwards, the valve body 111 is moved out of the valve body discharge port, and the first driving mechanism 321 drives the first lifting mechanism 322 and the second manipulator 323 to move together to the position of the fixing seat 21. The first lifting mechanism 322 drives the second manipulator 323 to move downwards, the valve body 111 is placed in the fixed seat 21, the second driving cylinder 3231 of the second manipulator 323 controls the two second movable arms 3232 to fold, and the two second movable arms 3232 are separated from the valve body 111. The first lifting mechanism 322 drives the second manipulator 323 to move upwards, and the first driving mechanism 321 returns the second manipulator 323 to the initial position to start repeating the material taking operation of the next round. At the same time, the delivery line 90 delivers the valve body 111 to the valve body detecting device 33.

The second and second elevating mechanisms 331 drive the fastening mechanism 332 and the two opening/closing detection mechanisms 333 to move down to the set positions, and the fastening mechanism 332 clamps the valve body 111 to prevent the valve body 111 from moving during the detection. Three third driving cylinders 3331 are respectively started to parallelly convey the three thimbles 3332 to the corresponding three channels 1111. If the three thimbles 3332 can enter smoothly within the set stroke, the valve body 111 is qualified, and the next assembly operation is carried out. If one thimble 3332 cannot be pushed into the channel 1111 or the pushing depth is not enough, the valve body 111 is not qualified. The valve body 111 is not subjected to the next assembling operation, and the transfer line 90 transfers it to the position of the third discard bin 92.

Thirdly, the delivery line 90 delivers the valve body 111 that is qualified for inspection to the position of the valve element unit 40. The valve core supply device 41 conveys the valve cores 112 to the valve core discharge port in sequence, and the valve cores 112 at the valve core discharge port are extruded into the clamping grooves of the clamping blocks 4232. When the first sensor 425 detects the valve core 112 in the card slot, the first horizontal driving cylinder 422 drives the gripping block 4232 to be transported to the position of the first manipulator 435. At the same time, the second sensor 426 detects whether the packing 1123 is present on the spool 112. The first driving cylinder 4352 drives the two first movable arms 4351 to fold, the thick rod portion 1121 of the valve core 112 is clamped, and the first lifting cylinder 432 drives the first manipulator 435 to ascend so as to move the valve core 112 out of the clamping groove. At this time, if the second sensor 426 detects the sealing ring 1123, the flipping cylinder 434 drives the first manipulator 435 to rotate, so that the thick rod segment 1121 of the valve element 112 is located above the thin rod segment 1122, the second horizontal driving cylinder 431 drives the first lifting cylinder 432 and the first manipulator 435 to move to the valve element transfer device 44, and the valve element transfer device 44 places the flipped thick rod segment 1121 in the valve body 111. If the second sensor 426 detects that the sealing ring 1123 is not present, the second horizontal driving cylinder 431 drives the first lifting cylinder 432 and the first manipulator 435 to move to the first material discharge bin 427, the first driving cylinder 4352 drives the two first movable arms 4351 to separate, and the valve core 112 falls into the first material discharge bin 427.

Fourth, the delivery line 90 delivers the valve body 111 and the valve body 112, which are assembled properly, to the lock valve element unit 50. The second lifting cylinder 53 drives the sliding plate 52, the stopper 553 and the first locking device 55 connected thereto to move down together to a set height. The first drive motor 551 drives the locking mechanism 552 downward and into precise alignment with the end of the stem section 1122 of the valve spool 112. The locking mechanism 552 drives the valve plug 112 to rotate so that the valve plug 112 is screwed with the valve body 111. When the bottom of the stopper 553 contacts the top of the plunger 54 and the torque value of the locking mechanism 552 is the set torque value, the valve element 112 and the valve body 111 are assembled to be qualified, and the next assembly process is continued. If the torque value of the locking mechanism 552 is different from the set torque value, the assembly is not qualified, and the subsequent assembly operation is not performed. Or, when the torque value of the locking mechanism 552 reaches the set torque value and the top of the marker rod 54 does not contact the bottom of the stopper 553, it indicates that the valve core 112 and the channel 1111 of the valve body 111 are not aligned correctly, and the assembly is not qualified, and the next operation is not performed. The rejected assembled product is transported out of the third reject bin 92.

Fifth, the delivery line 90 delivers the valve body 111 and the valve body 112, which are assembled properly, to the handle unit 60. The stoppers 745 of the two third movable arms 6221 of the third robot 622 are inserted into the corresponding escape openings 1132 of the handle 113 of the handle feeding device 61, and the handle 113 is gripped. The second driving mechanism 734621 drives the third manipulator 622 to move, and at the same time, the handle fastening device 63 fixes the valve core 112 in the fixed seat 21, and the third manipulator 622 makes the mounting hole 1131 of the handle 113 accurately aligned with the thin rod segment 1122 and placed at the end of the thin rod segment 1122.

Sixth, the delivery line 90 delivers the assembled valve body 111 and valve body 112 to the lock handle unit 70. The screw feeding bin 731 conveys the screw 114 to the screw outlet, and the screw 114 is pressed into the receiving groove 7351. The second driving mechanism 734621 drives the fixing block 735 to move, the screw 114 moves out of the opening 7333, the side wall of the base 733 presses the screw 114, the screw 114 presses the elastic member 7362, the elastic member 7362 contracts and the pulley 7363 rolls along the side wall of the guide groove 7332. When the screw 114 reaches the enlarged groove 7331, the screw 114 enters the enlarged groove 7331 by the elastic deformation force of the elastic member 7362 and passes through the through hole 1133 below the enlarged groove 7331, and the elastic member 7362 returns to the original state. The screw 114 exits the through hole 1133 and enters the conduit 738, and passes through the metal detector 737 and the second through slot 7442 into the third through slot. At this time, the metal detector 737 detects that the screw 114 passes through, and the second locking device 74 is activated to start the locking operation. The locking motor 742 drives the locking element 743 to move downwards to enter the third through groove and be connected with the top of the screw 114 in a pressing manner, and the locking element 743 drives the screw 114 to rotate, so that the screw 114 penetrates through the first mounting hole 11311 and is in threaded connection with the thin rod section 1122 of the valve core 112.

Seventh, a third material abandoning bin 92 is further arranged between the locking handle unit 70 and the sealing detection unit 80, and the valve body 111, the valve body 111 and the valve core 112 are screwed tightly, and then the valve body 111, the valve body 111 and the valve core 112 are all removed from the third material abandoning bin 92 when the torsion does not reach the standard and the screw 114 between the handle 113 and the valve core 112 is not locked in place.

Eighth, the conveying line 90 conveys the assembled stop valve 11 to the seal detection unit 80. The second driving device 81 transfers the stop valve 11 from the fixing base 21 into the airtightness detection device 82 for airtightness detection. The second driving device 81 transports the qualified stop valve 11 to the good product discharge bin 84, and transports the unqualified stop valve 11 to the second waste bin 83.
