Description

Technical Field

[0001] This invention relates to the field of roller skate manufacturing technology, and in particular to an automated production line for multiple roller skate models. Background Technology

[0002] In recent years, with the increasing health awareness of people and their love for recreational sports, ice skating has become increasingly popular, which has led to the continuous expansion of the roller skate market.

[0003] Traditional roller skates consist of components such as a plastic injection-molded upper, wheels, and brake pads. The plastic upper, wheels, and brake pads are primarily assembled manually after injection molding. This manual assembly process is quite tedious, requiring multiple steps including installing the upper and wheels, inserting spikes, and installing brake pads. This results in high labor costs, low efficiency, and inconsistent quality. Problems may arise, such as insecure wheel installation, asymmetry between the left and right wheels, and inconsistent screw tightening during spike installation, all affecting the overall performance and safety of the roller skates. Furthermore, variations in worker techniques and skill levels lead to inconsistent product quality and a high defect rate. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an automated production line for multiple models of roller skates, which solves the problems of high labor costs, low efficiency, inconsistent product quality, and high defect rate in existing manual roller skate assembly.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated production line for mixing multiple models of roller skates, wherein the roller skates include two shoe bodies and several rollers, and each shoe body and roller has a first through hole on its side wall. The side wall of each shoe body also has a nut mounting hole communicating with the first through hole. One shoe body has a brake pad, and both the brake pad and the shoe body have screw holes. The automated production line includes:

[0006] Two support seats, each of which is provided with several positioning seats. The positioning seats are provided with a second positioning groove for installing rollers. When the shoe body is fitted around the rollers and positioning seats, the first through holes on the shoe body and the rollers are connected. One of the support seats is provided with a first positioning groove for installing brake pads and a second through hole connected to the first positioning groove.

[0007] An automatic screw fastening mechanism, comprising:

[0008] Two movable plates, each of which is provided with several nut mounting slots;

[0009] A nut feeding device includes a nut conveying structure and a nut receiving plate, wherein the nut conveying structure is used to convey a number of nuts to the nut receiving plate;

[0010] The fourth material handling device includes a fourth robotic arm and a fourth material handling assembly. The fourth robotic arm is used to drive the fourth material handling assembly to move and pick up the nuts on the nut support plate and place them on the nut placement groove on the moving plate. At this time, the nuts protrude out of the nut placement groove.

[0011] The third material gripping device includes a third robotic arm and a third material gripping assembly. The third robotic arm is used to drive the third material gripping assembly to grip and place the support base with rollers, shoe body and brake pads / rollers and shoe body installed on the moving plate, so that the nut enters the nut mounting hole on the shoe body.

[0012] The first screw feeding device includes a first screw conveying structure and a first screw receiving plate. After the first screw conveying structure conveys a number of first screws to the first screw receiving plate, the fourth robot arm drives the fourth gripping assembly to grip the first screws on the first screw receiving plate and place them in the first through hole.

[0013] Two first locking screw devices include a first drive and a first head assembly, wherein the first drive is used to drive the first head assembly to move so that it secures the first screw to the nut;

[0014] A second screw-locking device includes a second screw delivery structure and a second screw head assembly, the second screw head assembly being arranged perpendicularly to the first screw head assembly, the second screw head assembly being used to screw a second screw into a screw-locking hole in a brake pad and a shoe body;

[0015] It also includes a conveyor belt, on which several sets of positioning modules are provided. Each set of positioning modules is provided with two support seats. Along the conveying direction of the conveyor belt, a roller brake pad feeding mechanism, a shoe upper feeding mechanism, an automatic screw locking mechanism, and a labeling mechanism are sequentially provided on one side of the conveyor belt.

[0016] Preferably, the fourth material gripping assembly includes two fourth movable plates that move closer to or further away from each other. Several fourth clamping plates are provided on the opposite side of the two fourth movable plates. Fixing columns are fixedly installed at the bottom of the two fourth clamping plates. The total width of the two fixing columns is smaller than the inner diameter of the nut. Semicircular grooves are provided on the opposite side of the two fourth clamping plates. The diameter of the two semicircular grooves is not greater than the diameter of the screw of the first screw.

[0017] Preferably, the first locking screw device further includes calibration rods, the number of which is the same as the number of the first batch head assemblies. The output end of the first drive unit is fixedly mounted on a first support plate, and the calibration rods and the first batch head assemblies are fixedly mounted on the first support plate. The movable plate is movable so that the first through hole is located directly below the calibration rods and the first batch head assemblies in sequence.

[0018] Preferably, the movable plate is provided with a second fixing mechanism for pressing and fixing the support seat onto the movable plate and a first fixing mechanism for pressing and fixing the shoe body onto the support seat.

[0019] Preferably, the third material gripping assembly includes a third driving member, two third clamping plates, and a limiting block. When the third driving member drives the two third clamping plates to move closer to each other to fix the support seat, the limiting block limits and abuts against the shoe body.

[0020] Preferably, the support base is further provided with several locking posts. When the shoe body is fitted around the roller and the positioning base, both outer sidewalls of the shoe body are in contact with the locking posts, and both inner sidewalls of the shoe body are in contact with the outer wall of the positioning base.

[0021] Preferably, spring positioning beads for fixing the roller are provided on both sides of the inner wall of the second positioning groove.

[0022] Preferably, the roller brake pad feeding mechanism includes a worktable and a first gripping device. The worktable is provided with a first material tray for placing brake pads, a second material tray for placing rollers, a fifth gripping device, a first transfer seat, a second transfer seat, a vision inspection mechanism, a flipping mechanism, a transfer mechanism, and a turntable that rotates. The turntable has several receiving grooves around its circumference to accommodate rollers. When the turntable rotates, each receiving groove passes sequentially through the vision inspection mechanism, the flipping mechanism, and the transfer mechanism. The fifth gripping device is used to grip and place the brake pads on the first material tray. On the second transfer seat, and on the second material tray, the rollers are gripped and placed into the receiving groove. The rollers have a smooth surface and a cut surface. The visual inspection mechanism is used to identify the smooth surface and the cut surface. The flipping mechanism is used to flip the rollers with the smooth surface or cut surface facing up in the receiving groove so that each roller faces the same direction. The transfer mechanism is used to grip and place the rollers that have passed through the flipping mechanism onto the first transfer seat. The first gripping device is used to grip and place the rollers on the first transfer seat and the brake pads on the second transfer seat into the second positioning groove and the first positioning groove, respectively.

[0023] Preferably, the shoe upper feeding mechanism includes a second gripping device and two conveyor lines for conveying the left and right shoe uppers respectively. The second gripping device is used to grip the left and right shoe uppers on the two conveyor lines respectively and place them on two support seats. At this time, the first through holes on the shoe upper and the roller are directly connected. The shoe upper abuts against the brake pad and is limited. The brake pad and the screw hole on the shoe upper are directly connected.

[0024] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0025] This invention uses a fourth gripping device to pick up nuts from the nut support plate and place them on the nut placement slot on the moving plate. Then, a third gripping device picks up the support base, which includes rollers, the shoe body, and brake pads, and places it on the moving plate, aligning the nut mounting holes on the shoe body with the nuts. The moving plate is controlled to move so that the first through hole on the shoe body is aligned with the first batch head assembly. After the first screw feeding device sequentially feeds several first screws to the first screw storage holes on the first screw support plate, the fourth gripping device picks up the first screws from the first screw support plate, aligns them with the first through holes on the shoe body and rollers, and inserts them for initial placement. The second batch head assembly is adjusted to move closer to the support base on the moving plate so that the second batch head assembly... The screw passes through the second through hole and is inserted into the locking screw hole of the brake pad and the shoe body to fix the brake pad and the shoe body, thus completing the fixation between the brake pad and the shoe body. Then, the moving plate is controlled to move so that the first screw is located directly below the first batch of head assemblies. The first drive component is controlled to drive the first batch of head assemblies to move, so that the first screw passes through the first through hole and nut of the shoe body and the roller, completing the fixation between the shoe body and the roller. This completes the assembly work between the shoe body, the roller and the brake pad. Compared with the existing manual assembly of roller skates, this not only greatly improves efficiency and reduces labor costs, but also, in the long run, avoids manual assembly, which can greatly reduce production costs and ensure the quality of assembled products, reducing the defect rate.

Detailed Implementation

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this invention.

[0043] This invention provides an automated production line for mixing multiple models of roller skates, such as... Figure 2 and Figure 5 As shown, the roller skate includes two shoe bodies 12 and several wheels 11. Both the shoe body 12 and the wheels 11 have first through holes on their side walls. The side wall of the shoe body 12 also has nut mounting holes 121 communicating with the first through holes. One of the shoe bodies 12 has a brake pad 13. Both the brake pad 13 and the shoe body 12 have screw holes 131. Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the automated production line includes:

[0044] Two support bases 4 are provided, each of which is provided with several positioning bases 5. The positioning bases 5 are provided with a second positioning groove 501 for installing the roller 11. When the shoe body 12 is fitted around the roller 11 and the positioning base 5, the first through hole on the shoe body 12 and the roller 11 are connected, which makes it convenient for the first screw to pass through the first through hole and be fixed with the nut. At this time, the roller 11 and the shoe body 12 are not fixed, and the roller 11 can rotate around the first screw. One of the support bases 4 is provided with a first positioning groove 401 for installing the brake pad 13 and a second through hole 403 connected to the first positioning groove 401, which makes it convenient for the second screw to pass through the second through hole 403 and enter the screw hole 131 of the brake pad 13 and the shoe body 12 to fix the shoe body 12 and the brake pad 13. For different models of roller skates, a support base 4 that can accommodate the shoe body 12, roller 11 and brake pad 13 of different models of roller skates can be used.

[0045] The automatic screw-locking mechanism 40 includes two moving plates 43, a nut feeding device 10, a fourth gripping device 14, a third gripping device 41, a first screw feeding device 9, two first screw-locking devices 6 and a second screw-locking device.

[0046] Each movable plate 43 is provided with several nut mounting slots (not shown in the figure);

[0047] like Figure 6 and Figure 10 As shown, the nut feeding device 10 includes a nut conveying structure and a nut support plate 103. The nut conveying structure is used to convey a number of nuts to the nut support plate 103. Specifically, the nut conveying structure includes a nut vibrating feeder 101 (an existing mechanism, the specific principle of which will not be described in detail) and a nut conveying channel 102. The nut support plate 103 is provided with a number of nut storage slots 1031. By setting a second translation component 104 to drive the nut support plate 103 to move, each nut storage slot 1031 is located sequentially at the discharge end of the nut conveying channel 102, thereby completing the sequential feeding of individual (hexagonal) nuts. The specific number of nuts used can be selected according to the number of rollers 11 that need to be installed on one shoe body 12.

[0048] like Figure 6 and Figure 8 As shown, the fourth material gripping device 14 includes a fourth robotic arm 141 and a fourth material gripping assembly 142. The fourth robotic arm 141 is used to drive the fourth material gripping assembly 142 to move and grip the nuts on the nut support plate 103 and place them on the nut placement groove on the moving plate 43. At this time, the nuts protrude from the nut placement groove, ensuring that when the shoe body 12 and the support base 4 are placed on the moving plate 43, the nuts can be placed in the nut mounting hole 121 on the side wall of the shoe body 12.

[0049] like Figure 1 , Figure 2 , Figure 6 and Figure 12 As shown, the third gripping device 41 includes a third robotic arm 411 and a third gripping assembly 412. The third robotic arm 411 is used to drive the third gripping assembly 412 to grip and place the support base 4 with roller 11, shoe body 12 and brake pad 13 / roller 11 and shoe body 12 on the moving plate 43, so that the nut enters the nut mounting hole 121 on the shoe body 12, thereby ensuring the subsequent locking and fixing of the first screw and nut.

[0050] like Figure 6 , Figure 9As shown, the first screw feeding device 9 includes a first screw conveying structure and a first screw receiving plate 93. After the first screw conveying structure conveys several first screws to the first screw receiving plate 93, the fourth robot arm 141 drives the fourth gripping component 142 to move and grip the first screws on the first screw receiving plate 93 and place them in the first through hole. The specific first screw conveying structure includes a first screw vibrating material plate 91 (an existing mechanism, the specific principle of which is not described in detail) and a first screw conveying channel 92. The first screw receiving plate 93 has several stepped first screw storage holes 931 for accommodating first screws. The first translation component 94 drives the first screw receiving plate 93 to move so that each first screw storage hole 931 is aligned with the discharge end of the first screw conveying channel 92 in sequence, thereby completing the sequential feeding of each first screw. The specific number of first screws used can be selected according to the number of rollers 11 that need to be installed on a shoe body 12.

[0051] In addition, to facilitate the subsequent gripping of the first screw on the first screw support plate 93 by the fourth gripping assembly 142 and placing it into the first through hole, a lifting structure is provided directly below the first screw support plate 93. The lifting structure includes a lifting cylinder 95 and a top plate 96. When it is necessary to remove the first screw in the first screw storage hole 931, the lifting cylinder 95 is adjusted to drive the top plate 96 to move upward, thereby pushing the first screw part out of the first screw storage hole 931, thus facilitating the gripping of the first screw by the fourth gripping assembly 142.

[0052] like Figure 6 and Figure 7 As shown, the two first screw-locking devices 6 include a first drive member 62 and a first head assembly 64. The first head assembly 64 includes a first head that is driven to rotate by a motor (this is prior art and will not be described in detail here). The first drive member 62 is used to drive the first head assembly 64 to move so that it fixes the first screw to the nut.

[0053] like Figure 6 , Figure 7 and Figure 11 As shown, a second screw-locking device includes a second screw delivery structure and a second screw head assembly 150. The second screw head assembly 150 includes a second screw head that is driven to rotate by a motor (this is prior art and will not be described in detail here). The second screw head assembly 150 is arranged perpendicularly to the first screw head assembly 64. The second screw head assembly 150 is used to screw the second screw into the screw-locking hole 131 of the brake pad 13 and the shoe body 12.

[0054] like Figure 6 and Figure 7As shown, the first screw-locking device 6 also includes a calibration rod 65 and a support frame 61. The first drive component 62 is fixedly installed on the support frame 61. The number of calibration rods 65 is the same as the number of the first batch head assembly 64. The output end of the first drive component 62 is fixedly installed on the first support plate 63. The calibration rods 65 and the first batch head assembly 64 are fixedly installed on the first support plate 63. The moving plate 43 is movable so that the first through hole is located directly below the calibration rods 65 and the first batch head assembly 64 in sequence. By setting the calibration rods 65, after the third material gripping component 412 grips and places the support seat 4 with rollers 11, shoe body 12 and brake pads 13 on the moving plate 43, in order to prevent small errors in the position between the shoe body 12 and the rollers 11, the calibration rods 65 are first used to penetrate the first through holes of the shoe body 12 and the rollers 11 to ensure that the positions of the two will not be offset, so that the first screw can be accurately inserted, thereby further ensuring the quality of roller skate assembly.

[0055] This section uses the assembly of brake pad 13, roller 11, and shoe body 12 into one roller skate as an example for explanation (assembling roller 11 and shoe body 12 into another roller skate only requires the missing step of assembling brake pad 13, which will not be described here):

[0056] 1. After the nut feeding device 10 sequentially feeds several nuts to the nut storage slot 1031 on the nut support plate 103, the fourth robotic arm 141 drives the fourth gripping assembly 142 to move and grip the nuts on the nut support plate 103 and place them on the nut placement slot on the moving plate 43. At this time, the nuts protrude out of the nut placement slot.

[0057] Second: Control the third robotic arm 411 to drive the third material gripping assembly 412 to grip the support seat 4, which is equipped with rollers 11, shoe body 12 and brake pads 13, and place it on the moving plate 43, so that the nut mounting hole 121 on the shoe body 12 is aligned with the nut and calibration rod 65.

[0058] 3. Control the first driving component 62 to drive the calibration rod 65 to move and insert into the first through hole, so as to ensure the accurate insertion and locking of the subsequent first screw;

[0059] Fourth: Control the movement of the moving plate 43 so that the first through hole on the shoe body 12 is aligned with the first batch of head assembly 64. After the first screw feeding device 9 sequentially feeds a number of first screws to the first screw storage hole 931 on the first screw receiving plate 93, control the fourth robot arm 141 to drive the fourth gripping assembly 142 to grab the first screws on the first screw receiving plate 93, align them with the first through hole on the shoe body 12 and the roller 11, and insert them for initial placement.

[0060] 5. Adjust the second batch head assembly 150 to move close to the support seat 4 on the moving plate 43 (specifically, it can be driven by a cylinder) so that the second screw passes through the second through hole 403 and is inserted into the locking screw hole 131 of the brake pad 13 and the shoe body 12 to fix the brake pad 13 and the shoe body 12, thereby completing the fixation between the brake pad 13 and the shoe body 12.

[0061] Sixth: Control the moving plate 43 to move so that the first screw is located directly below the first batch head assembly 64. Control the first driving component 62 to drive the first batch head assembly 64 to move so that the first screw passes through the first through hole and nut of the shoe body 12 and the roller 11, thus completing the fixation of the shoe body 12 and the roller 11, thereby completing the assembly work between the shoe body 12, the roller 11 and the brake pad 13.

[0062] Compared to existing manual assembly of roller skates, this method not only greatly improves efficiency and reduces labor costs, but also significantly reduces production costs in the long run by avoiding manual assembly, while ensuring the quality of assembled products and reducing the defect rate.

[0063] like Figure 6 and Figure 11 As shown, the automatic screw fastening mechanism 40, through the vertically arranged second screw head assembly 150 and the first screw head assembly 64, also includes a second screw feeding device 15. The second screw feeding device 15 includes a second screw vibrating feeder 151, a second screw conveying channel 152, a second screw receiving plate 153 (the second screw receiving plate 153 has a side groove for accommodating the second screw on the side facing the second screw conveying channel 152), and a second driving component 154 (which can be a cylinder). The second driving component 154 drives the second screw receiving plate 153 to be positioned at the outlet end of the second screw conveying channel 152 or at the end facing the second screw head of the second screw head assembly 150. This allows the second screw to be fed from the second screw vibrating feeder 151 through the second screw conveying channel 152 to the second screw receiving plate 153, after which the second driving component 154 can be adjusted. 4. Move the second screw support plate 153 to face the second screw head, then adjust the second screw head assembly 150 to move closer to the second screw support plate 153, so that it can remove the second screw from the side groove of the second screw support plate 153. Then adjust the second screw head assembly 150 and the second screw support plate 153 to reset. The reset of the second screw support plate 153 to face the discharge end of the second screw conveying channel 152 can avoid the movement of the moving plate 43, and facilitate the subsequent adjustment of the second screw head assembly 150 to move closer to the support seat 4 on the moving plate 43. This allows the second screw to pass through the second through hole 403 and be inserted into the locking screw hole 131 of the brake pad 13 and the shoe body 12 to fix the brake pad 13 and the shoe body 12. With this setting, the overall structure is reasonably arranged, and the assembly of the second screw and the first screw can be carried out in an orderly manner without interference.

[0064] like Figure 6 , Figure 8 , Figure 9 and Figure 10 As shown, the fourth material gripping assembly 142 includes two fourth movable plates 1421 that move closer to or further away from each other (specifically driven by a cylinder). Several fourth clamping plates 1422 are provided on the opposite side of the two fourth movable plates 1421 (the specific number can be determined according to the number of rollers 11 installed on a shoe body 12). Fixing posts 1423 are fixedly installed at the bottom of the two fourth clamping plates 1422. The total width of the two fixing posts 1423 is smaller than the inner diameter of the nut. Semicircular grooves 1424 are provided on the opposite side of the two fourth clamping plates 1422. The diameter of the two semicircular grooves 1424 is not greater than the diameter of the screw of the first screw.

[0065] When it is necessary to pick up the nuts in the nut storage slot 1031, the fourth robotic arm 141 drives the fourth gripping assembly 142 to move, so that the two fixed columns 1423 enter the nut. Then, the two fourth movable plates 1421 are adjusted to move away from each other, thereby pressing and fixing the nut, and completing the automatic picking up of the nut.

[0066] When it is necessary to remove the first screw from the first screw storage hole 931, the lifting cylinder 95 is adjusted to drive the top plate 96 to move upward, thereby pushing the first screw part out of the first screw storage hole 931. Then, the two fourth movable plates 1421 are adjusted to move closer to each other, so that the inner walls of the two semi-circular grooves 1424 contact the screw of the first screw, thereby completing the clamping and removal of the first screw.

[0067] like Figure 6 and Figure 7 As shown, the movable plate 43 is provided with a second fixing mechanism 8 for pressing and fixing the support base 4 onto the movable plate 43 and a first fixing mechanism 7 for pressing and fixing the shoe body 12 onto the support base 4.

[0068] The first fixing mechanism 7 includes a telescopic cylinder, a first rotary motor 71, and a first pressure plate 72. The second fixing mechanism 8 includes a pressing drive cylinder, a second rotary motor, and a second pressure plate 81. After the support base 4 is placed on the moving plate 43, the second rotary motor drives the second pressure plate 81 to rotate, so that the second pressure plate 81 is directly above the support base 4. Then, the pressing drive cylinder is adjusted to drive the second pressure plate 81 to move down, thereby pressing and fixing the support base 4 onto the moving plate 43. Then, the first rotary motor 71 is adjusted to drive the first pressure plate 72 to rotate, so that the first pressure plate 72 is facing the shoe body 12. Then, the telescopic cylinder is adjusted to drive the first rotary motor 71 and the first pressure plate 72 to move closer to the shoe body 12, thereby completing the fixing of the shoe body 12. With this setting, the positions of the shoe body 12, roller 11, and support base 4 can be kept relatively stable. During the subsequent movement of the moving plate 43, the positions of the shoe body 12, roller 11, and support base 4 will not change, thereby ensuring the accurate insertion of the calibration rod 65, the first screw, and the second screw.

[0069] like Figure 2 and Figure 12 As shown, the third material gripping 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 closer to each other to fix the support seat 4, the limiting block 4123 limits and abuts against the shoe body 12. At this time, the brake pad 13 is limited and abutted by the shoe body 12. The limiting block 4123 can be set according to the shape of the shoe body 12.

[0070] When the two third clamping plates 4121 are adjusted to clamp and fix the support base 4, the limiting block 4123 limits and abuts against the shoe body 12, thereby completing the fixation of the support base 4 and the roller 11, shoe body 12 and brake pad 13 on it, thereby completing the automatic material picking work of the roller 11, shoe body 12 and brake pad 13 to be assembled for the first screw and the second screw.

[0071] like Figure 2 , Figure 3 and Figure 4 As 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.

[0072] With this setting, it can be ensured that when the shoe body 12 is installed and sleeved 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.

[0073] like Figure 3 and Figure 4As 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.

[0074] 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.

[0075] 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.)

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.
