[0057] As shown in Figure 24 , next, the first index plate 21 drives and the first cutter head clamp 211 assembled with the movable blade 12 and the briquetting 13 enters the movable cutter group hot pressing station C, at this time, the first cutter head clamp 211 is just located between the movable cutter group briquetting 52 and the movable cutter group heating briquetting 53, the movable cutter group heating briquetting 53 heats and warms the movable cutter group pressing column 54, the briquetting lifting cylinder 55 drives the movable cutter group briquetting 52 to abut against the briquetting 13 above, and the hot pressing lifting cylinder 56 drives the movable cutter group pressing column 54 to insert into the corresponding first cutter head through hole 212, so that it abuts against the briquetting snap ring 132, and the briquetting snap ring 132 is fixed and assembled with the movable blade snap hole 121 into a fixed integrated movable cutter group 17 after hot melting the briquetting snap ring 132, and the assembly of the movable cutter group 17 is completed.

[0058] As shown in Figure 3 , Figure 17 , Figure 18As shown, in the automatic shaving head assembly line of the present application, the second indexing disc 22 also drives the second head clamp 221 to rotate intermittently, and the head shell 1 is uniformly placed into the shell vibration disc 64. After the shell vibration disc 64 vibrates and screens the head shell 1, the end of the head shell 1 with the cartridge 15 is upward and in a uniform state in the preset direction into the shell feeding channel 651. The shell vibration generator 60 is used to drive the head shell 1 in the shell feeding channel 651 to continuously move to the shell feeding plate 631. When the head shell 1 enters the shell feeding plate 631, since the shell feeding groove 6321 is in communication with the shell feeding channel 651 at this time, the head shell 1 will directly enter the shell feeding groove 6321, and the shell baffle 67 is used to prevent the head shell 1 from escaping from the end of the shell feeding groove 6321 away from the shell feeding channel 651. When the head shell 1 directly enters the shell feeding groove 6321, the shell feeding sensor detects that the head shell 1 is completely in the shell feeding groove 6321. At this time, the shell correction air cylinder 66 on both sides of the shell feeding groove 6321 drives the shell correction rod 661 to position and correct the head shell 1 in the shell feeding groove 6321 for subsequent clamping, and also prevents the head shell 1 from escaping from the shell feeding groove 6321 during feeding. At the same time, the shell feeding cylinder 632 also drives the shell feeding plate 631 to transport the head shell 1 towards the second indexing disc 22. Since the shell feeding plate 631 moves, the shell feeding channel 651 cannot advance against the shell feeding plate 631, realizing the one-by-one feeding of the head shell 1. At the same time, the shell correction air cylinder 66 releases the fixation on the surface of the head shell 1, facilitating subsequent material transfer. At this time, the second indexing disc 22 drives the second head clamp 221 into the shell loading station E. The shell longitudinal driving mechanism 614 drives the shell material transfer suction disc 612 to move downward and adhere to the head shell 1. The shell material transfer suction disc 612 generates negative pressure to thereby adsorb the head shell 1. The shell longitudinal driving mechanism 614 moves upward and is driven by the shell transverse driving mechanism 613 to move above the second head clamp 221. Then the shell longitudinal driving mechanism 614 places the head shell 1 in the second head clamp 221. At this time, the shell material transfer suction disc 612 cancels the negative pressure or blows air. The shell magnet in the second head clamp 221 adsorbs the head shell 1. At the same time, the shell unloading cylinder drives the shell unloading ejector shaft to axially ascend and descend to push the head shell 1 that is mistakenly adsorbed in some cases into the second head clamp 221. At the same time, the head detection sensor 234 of the fixed disc 23 detects the head shell 1 in the shell accommodating groove, completing the automatic loading of the head shell 1. Next, the second indexing disc 22 drives the second head clamp 221 into the fixed blade loading station F. Since the movable blade conveying mechanism 3 and the fixed blade conveying mechanism F1 are consistent in structure, and the movable blade feeding mechanism 31 and the fixed blade feeding mechanism F2 are also consistent, only the movable blade 12 in the movable blade feeding rack 33 is replaced by the fixed blade 11, and the fixed blade feeding process can be directly used. Therefore, the fixed blade feeding process will not be described again.It is only necessary to know that the fixed blade 11 is placed above the cutter head housing 1 inside the second cutter head fixture 221 via the fixed blade loading station F, and that the fixed blade retaining hole 111 is aligned with the preset position of the cutter head housing 1, and that the fixed blade 11 is attracted to the second cutter head fixture 221 by the cutter head magnet 230.

[0059] like Figure 16 As shown, the second cutter head clamp 221, which is loaded with the fixed blade 11 and the cutter head housing 1, will then enter the fixed blade assembly heat treatment station G along with the second indexing plate 22. At this time, the second cutter head clamp 221 is located between the fixed blade assembly push block 72 and the fixed blade assembly heating block 73. The fixed blade assembly heating block 73 will heat the fixed blade assembly heat treatment column 74. The fixed blade assembly push block cylinder 75 will drive the fixed blade assembly push block 72 to press against the second indexing plate 22 from below. The fixed blade assembly heat treatment cylinder 76 will drive the fixed blade assembly heat treatment column 74 to be inserted into the corresponding fixed blade retaining hole 111. After the fixed blade retaining hole 111 is heat-melted, the fixed blade 11 and the cutter head housing 1 are fixedly assembled into a fixed blade assembly 18, thus completing the assembly of the fixed blade assembly 18.

[0060] like Figure 25 As shown, at this time, the first blade holder 21 located in the moving blade assembly conveying station D of the first indexing plate 21 contains the assembled moving blade assembly 17. The second indexing plate 22 will drive the second blade holder with the fixed blade assembly 18 into the moving blade assembly assembly station H. At this time, the moving blade assembly lifting cylinder 84 will drive the moving blade assembly gripper 83 to clamp the moving blade assembly 17 in the first blade holder 21. The moving blade assembly transfer cylinder 85 will drive the moving blade assembly 17 to be sent to the second blade holder 221 after passing through the oil cylinder 82 and then into the second blade holder 221 to fit with the fixed blade assembly 18, thereby improving the blade sensitivity of the shaver head and completing the combination of the moving blade assembly 17 and the fixed blade assembly 18.

[0061] like Figures 6-14As shown, at this time the second index plate 22 will bring the second cutter head clamp 221 into the torsion spring assembly station I, which mainly acts on the torsion spring 14 at the torsion spring clamp 94 to extract and send it to the second cutter head clamp 221 loaded with the moving cutter group 17 and the fixed cutter group 18, so that the torsion spring transfer mechanism 93 replaces the worker to assemble the torsion spring 14 into the moving cutter group 17 and the fixed cutter group 18, the torsion arm 142 will be installed in the pressing block clamping groove 133 at both ends of the pressing block 13, and the torsion spring body 141 and the torsion spring connecting part 143 will be installed in the clamping seat 15 and the connecting part seat 16 on the cutter head housing 1 respectively, wherein the torsion spring 14 is uniformly placed into the torsion spring vibration disc 96, and after being screened by the torsion spring vibration disc 96, it enters the torsion spring walking channel 953 in the same state. At this time, the torsion spring conveying bead 955 and the torsion spring feeding spring 954 form an elastic clamping structure clamped on the side of the torsion spring walking channel 953 close to the torsion spring clamp 94. Under normal circumstances, the torsion spring conveying bead 955 will pop out of the surface of the torsion spring conveying plate 951 due to the elastic force of the torsion spring feeding spring 954, thereby preventing the inclined torsion spring 14 from sliding downward due to its gravity. The torsion spring feeding claw 971 is arranged on both sides of the torsion spring walking channel 953, and the torsion spring feeding cylinder 972 can drive the lowermost torsion spring 14 to move downward to press the torsion spring conveying bead 955 into the torsion spring conveying plate 951, thereby making the torsion spring 14 slide into the adjacent torsion spring clamp 94, and after completion, the feeding reset cylinder 973 drives the torsion spring feeding claw 971 to move downward, and then the torsion spring feeding cylinder 972 rises, and then the feeding reset cylinder 973 sends the torsion spring feeding claw 971 to the position above the current lowermost torsion spring 14 to form a quadrilateral structure, thereby completing the reset, and thereby the torsion spring feeding assembly can intermittently send the torsion spring 14 from the torsion spring walking channel 953 to the torsion spring clamp 94, realizing automatic mechanical feeding.

[0062] When the torsion spring 14 in the torsion spring conveying mechanism 9 enters the torsion spring clamp 94, the body positioning pull plate 925 pulls the torsion spring body 141 into the torsion spring accommodating groove 941, and cooperates with the torsion spring clamp 94 to make the torsion spring body 141 enter the torsion spring accommodating groove 941 and stay above the torsion spring top plate 922, and the torsion arm positioning push plate 927 also pushes the two sides of the torsion arm 142 to the body positioning pull plate 925, so that the two sides of the torsion arm 142 are deformed to the middle and then the torsion arm 142 stays in the torsion arm positioning space 928 formed between the torsion arm positioning push plate 927 and the body positioning pull plate 925, so that the torsion arm 142 stays above the torsion spring top plate 923 and is fixed to avoid rotating out, at this time the torsion spring rotating drive machine (motor) drives the two sides of the torsion spring clamp 94 on the torsion spring feeding seat 92 to adjust the position, and is accurately positioned through the bottom photoelectric sensor, so that the torsion spring conveying mechanism on this side can wait for feeding, and the torsion spring clamp 94 at the other end can transfer the torsion spring 14 in the torsion spring clamp 94 to the second tool clamp 221 of the torsion spring assembly station I through the torsion spring rotating mechanism 93, so as to realize one-to-wait, improve the efficiency of torsion spring assembly, and realize automatic assembly of torsion spring.

[0063] When the torsion spring rotating seat 98 extracts the torsion spring 14 at the torsion spring clamp 94, the torsion spring longitudinal cylinder 932 drives the body profiling groove 981 and the torsion arm clamping groove 982 of the torsion spring rotating seat 98 to abut the torsion spring accommodating groove 941 and the torsion arm positioning space 928 at the torsion spring clamp 94 respectively, at this time the torsion spring top cylinder 921 drives the torsion spring top plate 922 and the torsion spring top piece 923 to pass through the torsion spring clamp 94, and then the torsion spring 14 is pushed away from the torsion spring clamp 94 and enters the torsion spring rotating seat 98, wherein the body locking cylinder 983 drives the body locking shaft 9831 to penetrate into the torsion spring body 141 to fix the torsion spring body 141 on the body profiling groove 981, the torsion arm 142 is fixed by the elastic potential on both sides abutting the arc-shaped hole-shaped torsion arm clamping groove 982, at this time the pressing block locking cylinder 231 on the fixed disc 23 drives the pressing block locking rod 232 to insert into the pressing block fixing seat 131 in the torsion spring assembly station I to fix it, then the torsion spring longitudinal cylinder 932 and the torsion spring transverse cylinder 935 drive the torsion spring 14 to abut the second cutter head clamp 221 above the second indexing disc 22, at this time the body locking cylinder 983 drives the body locking shaft 9831 to disengage from the torsion spring body 141, the body unloading cylinder 984 drives the body unloading plate 9841 to pass through the torsion spring rotating seat 98, and then pushes the torsion spring body 141 out of the body profiling groove 981, and then the torsion spring body 141 is pressed into the clamping seat 15, the torsion arm unloading cylinder 985 drives the torsion arm unloading ejector pin 9851 to pass through the torsion arm unloading hole 9821, and then pushes the torsion arm 142 on both sides out of the torsion arm clamping groove 982, and then the torsion arm 142 is clamped in the pressing block clamping groove 133 on both sides of the pressing block 13, at the same time the torsion arm unloading cylinder 985 also synchronously drives the connecting part unloading plate 9853 to pass through the connecting part unloading groove 9822, and then pushes the torsion spring connecting part 143 out of the connecting part unloading groove 9822, and then the torsion spring connecting part 143 is clamped into the connecting part seat 16 of the cutter head housing 1, realizing the automatic assembly of the torsion spring and realizing the full-automatic assembly of the torsion spring 14.

[0064] As shown in Figures 3-5 , Figure 25 , at this time the second indexing disc 22 drives the assembled razor cutter head into the visual re-inspection station K, the luminous body 233 corresponding to the visual re-inspection station K in the fixed disc 23 illuminates the visual re-inspection station K, and the visual detection camera K2 takes a photo of the second cutter head clamp 221 in the current position and compares it with the preset photo, and then cooperates with the subsequent cutter head unloading mechanism J1 to screen, that is, puts the qualified ones into the qualified material barrel and the unqualified ones into the artificial re-inspection barrel, completing the automatic screening.

[0065] As shown in Figures 3-5As shown, at this time the second index plate 22 will drive the rechecked razor head into the razor head unloading station J. The movable cutter assembly mechanism 8 has the same structure as the razor head unloading mechanism J1. Only by placing the movable cutter assembly mechanism 8 into the razor head unloading station J and changing the movable cutter assembly mechanism 8 to clamp the assembled razor head, the movable cutter assembly mechanism 8 can be directly used. Therefore, the details are not described here. It is only necessary to know that the movable cutter assembly mechanism 85 and the movable cutter assembly lifting cylinder 84 can be used to drive the movable cutter assembly mechanism 83 to move the razor head in the second cutter head clamp 221 out of the second index plate 22 for unloading, thereby realizing the full-automatic razor head assembly.
