[0019] As shown in Figure 6 , Figure 8 , Figure 9 and Figure 10 , the fourth material grabbing assembly 142 comprises two fourth movable plates 1421 (which can be driven by a pneumatic cylinder) moving close to or away from each other, a plurality of fourth clamping plates 1422 (the specific number can be determined according to the number of rollers 11 installed on one shoe body 12) are arranged opposite to one side of the two fourth movable plates 1421, a fixed column 1423 is fixedly installed at the bottom of each of the two fourth clamping plates 1422, the total width of the two fixed columns 1423 is smaller than the inner wall diameter of the nut, and a semicircular groove 1424 is formed on the side of each of the two fourth clamping plates 1422 opposite to the side where the fixed column 1423 is arranged, and the diameter of the semicircular groove 1424 is not greater than the diameter of the screw rod of the first screw; When the nut on the nut temporary storage groove 1031 needs to be taken out, the fourth material grabbing assembly 142 is driven by the fourth mechanical arm 141 to move, so that the two fixed columns 1423 enter the nut, and then the two fourth movable plates 1421 are adjusted to move away from each other, so that the nut is tightly fixed, and the automatic taking of the nut is completed; When the first screw in the first screw temporary storage hole 931 needs to be taken out, after adjusting the lifting cylinder 95 to drive the top plate 96 to move upward, thereby partially ejecting the first screw from the first screw temporary storage hole 931, adjust the two fourth movable plates 1421 to move close to each other, thereby the inner wall of the two semicircular grooves 1424 is in contact with the screw rod of the first screw, thereby completing the clamping and taking out of the first screw.

[0020] As shown in Figure 6 and Figure 7 , the moving plate 43 is provided with a second fixing mechanism 8 for tightly fixing the support seat 4 on the moving plate 43 and a first fixing mechanism 7 for tightly fixing the shoe body 12 on the support seat 4; The first fixing mechanism 7 includes a telescopic cylinder, a first rotary motor 71 and a first pressing plate 72, and the second fixing mechanism 8 includes a pressing driving cylinder, a second rotary motor and a second pressing plate 81. After the support seat 4 is placed on the moving plate 43, the second rotary motor is driven to rotate the second pressing plate 81, so that the second pressing plate 81 is located directly above the support seat 4, and then the pressing driving cylinder is adjusted to drive the second pressing plate 81 to move downward, thereby tightly fixing the support seat 4 on the moving plate 43. Then the first rotary motor 71 is adjusted to rotate the first pressing plate 72, so that the first pressing plate 72 is opposite to the shoe body 12, and then the telescopic cylinder is adjusted to drive the first rotary motor 71 and the first pressing plate 72 to move close to the shoe body 12, thereby completing the fixing of the shoe body 12. By such arrangement, the positions of the shoe body 12, the roller 11 and the support seat 4 can be relatively stable, and the positions of the shoe body 12, the roller 11 and the support seat 4 will not change during the subsequent movement of the moving plate 43, thereby ensuring the accurate insertion of the alignment rod 65, the first screw and the second screw.

[0021] As shown in Figure 2 and Figure 12 , the third grabbing assembly 412 includes a third driving member 4122, two third clamping plates 4121 and a limiting block 4123. When the third driving member 4122 drives the two third clamping plates 4121 to move close to each other to fix the support seat 4, the limiting block 4123 limits and abuts against the shoe body 12, and at this time the brake pad 13 is limited and abutted by the shoe body 12. The limiting block 4123 can be shaped according to the shoe body 12. When the two third clamping plates 4121 are adjusted to clamp and fix the support seat 4, the limiting block 4123 limits and abuts against the shoe body 12, thereby completing the fixing of the support seat 4, the roller 11, the shoe body 12 and the brake pad 13 thereon, and completing the automatic taking out of the roller 11, the shoe body 12 and the brake pad 13 of the first screw and the second screw to be assembled.

[0022] As shown in Figure 2 , Figure 3 and Figure 4As shown, the support base 4 is also provided with several locking posts 402. When the shoe body 12 is fitted around the roller 11 and the positioning base 5, both outer side walls of the shoe body 12 are in contact with the locking posts 402, and both inner side walls of the shoe body 12 are in contact with the outer wall of the positioning base 5. With this setting, it can be ensured that when the shoe body 12 is installed around the roller 11 and the positioning seat 5, the shoe body 12 can be limited and fixed, and will not arbitrarily shift in position in the horizontal direction perpendicular to the locking post 402.

[0023] like Figure 3 and Figure 4 As shown, spring positioning beads 502 for fixing the roller 11 are provided on both sides of the inner wall of the second positioning groove 501. By setting the spring positioning beads 502 (which is an existing structure and the specific principle will not be described here), when the roller 11 is placed in the second positioning groove 501, the spring positioning beads 502 can abut and fix the roller 11, thereby ensuring its stability in the second positioning groove 501.

[0024] like Figure 1 As shown, it also includes a conveyor belt 1, which is provided with several sets of positioning modules 2. Each set of positioning modules 2 is provided with two support seats 4. Along the conveying direction of the conveyor belt 1, a roller brake pad feeding mechanism 20, a shoe upper feeding mechanism 30, an automatic screw locking mechanism 40 and a labeling mechanism 50 are sequentially provided on one side of the conveyor belt 1. With this setup, manual placement of the rollers 11 and the shoe body 12 onto the support base 4 can be avoided, achieving fully automated processing of the entire production line. The labeling mechanism 50 includes a seventh robotic arm, a label peeler, and a sixth material gripping device. The sixth material gripping device includes a sixth robotic arm 51 and a sixth material gripping assembly 52 (which can be a pneumatic gripper). The sixth robotic arm 51 controls the sixth material gripping assembly 52 to move and remove the assembled roller skates from the support base 4. Then, the seventh robotic arm picks up the labels peeled off from the label peeler and attaches them to the roller skates. Finally, the sixth robotic arm 51 controls the placement of the skates onto another conveyor belt. (The specific label peeler and corresponding labeling principle are existing technologies and will not be described in detail here.)

[0025] like Figure 1 , Figure 13 , Figure 14 and Figure 15As shown, specifically, the roller brake pad feeding mechanism 20 includes a worktable 201 and a first gripping device 27. The worktable 201 is provided with a first tray 17 for placing brake pads 13, a second tray 18 for placing rollers 11, a fifth gripping device 16, a first transfer seat 23, a second transfer seat 25, a vision inspection mechanism 26, a flipping mechanism 21, a transfer mechanism 22, and a rotating turntable 19. The turntable 19 has several receiving slots 191 around its circumference to receive rollers 11. When the turntable 19 rotates, each receiving slot 191 passes through the vision inspection mechanism 26, the flipping mechanism 21, and the transfer mechanism 22 in sequence. The fifth gripping device 16 is used to neatly and uniformly place the brake pads 13 on the first tray 17. Because the smooth surface and rough cut surface of the rollers 11 are difficult to distinguish with the naked eye, the rollers 11 in the second tray 18 are not neatly placed and need to be identified by the subsequent vision inspection mechanism 26. At the same time, it avoids (Error occurs in manual visual identification) The rollers are picked up and placed on the second transfer seat 25, and the rollers 11 on the second tray 18 are picked up and placed in the receiving groove 191. The rollers 11 have a smooth surface and a cut surface (to ensure the aesthetics of the roller skates, the smooth surface of the rollers 11 is on the outside, while the rough cut surface is on the inside, so a visual inspection mechanism 26 is needed for identification before uniform placement). The visual inspection mechanism 26 (existing technology, not described in detail here) is used to identify the smooth surface and the cut surface. The flipping mechanism 21 is used to flip the rollers 11 with the smooth surface or cut surface facing up in the receiving groove 191 so that each roller 11 faces the same direction. The transfer mechanism 22 is used to pick up the rollers 11 that have passed through the flipping mechanism 21 and place them on the first transfer seat 23. The first picking device 27 is used to pick up the rollers 11 on the first transfer seat 23 and the brake pads 13 on the second transfer seat 25 and place them in the second positioning groove 501 and the first positioning groove 401 respectively. After the brake pad 13 on the first material tray 17 is placed on the second intermediate turntable 25 by the fifth material gripping device 16, and the roller 11 with the smooth and cut surfaces to be identified is placed in the receiving groove 191, the turntable 19 is driven to rotate by the motor, thereby moving the roller 11 directly below the vision inspection mechanism 26. After detection by the vision inspection mechanism 26, when it is necessary to flip the roller 11, the turntable 19 continues to rotate, so that the roller 11 with the surface to be flipped moves to face the flipping mechanism 21. The flipping mechanism 21 includes an eighth robotic arm, a flipping motor 211, and a flipping gripper 212 (which can be a pneumatic gripper, as is the prior art). When the eighth robotic arm drives the flipping gripper 212 to move and grip the roller 11 with the surface to be flipped away from the receiving groove 191 to ensure that it can rotate, the flipping motor 211 is controlled to drive the flipping gripper 212 to rotate. The roller 11 is rotated 180 degrees and then placed back into the receiving slot 191. Then, the turntable 19 is rotated so that the rotated roller 11 is facing the transfer mechanism 22. The transfer mechanism 22 includes a ninth robotic arm 221 and a transfer gripper 222 (which can be a pneumatic gripper, which is the prior art). When the roller 11 does not need to be flipped, it is directly rotated and transported to the transfer mechanism 22 after being identified by the vision detection mechanism 26. The ninth robotic arm 221 drives the transfer gripper 222 to take out the roller 11 from the receiving slot 191 of the vision detection mechanism 26 and the flipping mechanism 21 and place it on the first transfer seat 23. The first transfer seat 23 can move horizontally driven by the third translation component 24, so as to ensure that the transfer mechanism 22 can rotate multiple rollers 11 sequentially onto the first transfer seat 23 with the same stroke each time. After placing the roller 11 and brake pad 13 to be assembled on the first transfer seat 23 and the second transfer seat 25 respectively, the first material gripping device 27 sequentially places the roller 11 on the first transfer seat 23 and the brake pad 13 on the second transfer seat 25 into the second positioning groove 501 and the first positioning groove 401.

[0026] The specific first gripping device 27 includes a first robotic arm 271 and a first gripping assembly 272 (a pneumatic gripper can be used here). The first robotic arm 271 drives the first gripping assembly 272 to move so that the brake pad 13 on the second transfer seat 25 can be placed in the first positioning groove 401, and the roller 11 on the first transfer seat 23 can be placed in the second positioning groove 501.

[0027] like Figure 13 , 15As shown, specifically, the fifth gripping device 16 includes a fifth robotic arm 161 and a fifth gripping assembly 162. The fifth gripping assembly 162 includes a first suction cup 1621, a second suction cup 1622, and a fifth support plate 1623. The output end of the fifth robotic arm 161 is fixedly mounted on the fifth support plate 1623. Several first suction cups 1621 for adsorbing brake pads 13 on the first material tray 17 and second suction cups 1622 for adsorbing rollers 11 on the second material tray 18 are fixedly mounted on the bottom of the fifth support plate 1623. Then, they are respectively transported to the second transfer seat 25 and the receiving groove 191 by the fifth robotic arm 161. After that, when the turntable 19 rotates, the rollers 11 placed in the receiving groove 191 pass through the vision inspection mechanism 26, the flipping mechanism 21, and the transfer mechanism 22 in sequence.

[0028] like Figure 1 As shown, the shoe upper feeding mechanism 30 includes a second gripping device 31 and two conveyor lines for conveying the left shoe upper 12 and the right shoe upper 12 respectively. The second gripping device 31 is used to grip the left shoe upper 12 and the right shoe upper 12 on the two conveyor lines and place them on two support seats 4 respectively. At this time, the first through hole on the shoe upper 12 and the roller 11 are directly connected. The shoe upper 12 abuts against the brake pad 13 for limiting. The brake pad 13 and the screw hole 131 on the shoe upper 12 are directly connected. Specifically, the second gripping device 31 may include a second robotic arm and a second gripping assembly (which may be a pneumatic gripper). The second robotic arm drives the second gripping assembly to place the left shoe upper 12 and the right shoe upper 12 on the two conveyor lines on the support seats 4 respectively, thereby completing the automatic feeding of the shoe upper 12 of a pair of roller skates.
