Description

Technical Field

[0001] This invention belongs to the field of tire molding technology, specifically relating to an intelligent production line for seamless solid tire molding. Background Technology

[0002] Non-marking solid tires are currently mainly available in white, green, and gray. Due to their lack of black markings, they are specifically designed for use in high-end manufacturing, medical, and pharmaceutical industries where high cleanliness is required on epoxy flooring. CN 121133176 A discloses an intelligent molding production system for solid tires. However, non-marking solid tires still require manual application of adhesive patches to the tire sidewalls to achieve color consistency with the working environment. Current production systems lack the process of manually applying adhesive patches to the tire sidewalls. Furthermore, each process, such as material loading, base adhesive wrapping, middle adhesive wrapping, tread adhesive wrapping, and unloading, requires a corresponding robot, resulting in at least four robots. This leads to unreasonable space layout, low robot utilization, and high equipment costs. Summary of the Invention

[0003] The present invention aims to provide an intelligent molding production line for non-marking solid tires, a fully automated and efficient production line that solves the problems of the lack of intelligent molding production system for non-marking solid tires and the unreasonable space layout and high equipment cost of existing solid tire production lines.

[0004] Therefore, the technical solution adopted by this invention is as follows: a non-marking solid tire intelligent molding production line, comprising two quick drum changing systems, a rubber sleeve feeding system, a base rubber and middle rubber winding system, a non-marking tire sidewall patching system, a non-marking tire tread rubber winding system, and a finished product weighing and unloading system; the base rubber and middle rubber winding system includes a six-axis robot, a base rubber pressing machine, and a middle rubber pressing machine; the rubber sleeve feeding system, the base rubber pressing machine, the middle rubber pressing machine, the quick drum changing system, and the non-marking tire sidewall patching system are arranged clockwise around the six-axis robot, facilitating the six-axis robot to remove the rubber sleeve from the rubber sleeve feeding system, and... After the base adhesive is wrapped with base adhesive and the middle adhesive in sequence by the base adhesive and the middle adhesive to form the tire blank, it is placed at the left end of the non-marking tread adhesive wrapping system. The non-marking tread adhesive wrapping system includes a six-axis robot II, a transition table, and a non-marking tread adhesive wrapping machine. The quick drum changing system, the right end of the non-marking tread adhesive wrapping system, the transition table, the non-marking tread adhesive wrapping machine, and the finished product weighing and unloading system are arranged clockwise around the six-axis robot II. This makes it convenient for the six-axis robot I to pick up the tire blank from the right end of the non-marking tread adhesive wrapping system, temporarily place it on the transition table, readjust it to the center, pick it up, and then wrap the tire blank with tread adhesive by the non-marking tread adhesive wrapping machine before placing it in the finished product weighing and unloading system.

[0005] As a preferred embodiment of the above solution, the quick drum changing system includes two forming units placed on a mounting platform, and the forming drums on the two forming units correspond to two specifications of non-marking solid tires, namely 8-inch to 14-inch and 15-inch to 20-inch. The two quick drum changing systems can be used by six-axis robot one and six-axis robot two to automatically change the forming unit corresponding to the tire specifications. The transition platform is used to temporarily place the tire blank for six-axis robot two to readjust and center it for picking up. The finished product weighing and unloading system includes a weighing platform for weighing the tire blank and an unloading gantry robot mechanism for taking away qualified tire blanks. The structure is reasonably designed.

[0006] More preferably, the sleeve feeding system includes a feeding conveyor belt and a sleeve clamping and lifting mechanism located at the right end of the feeding conveyor belt; the feeding conveyor belt is mounted on the main conveyor frame and equipped with a conveying drive component for driving the feeding conveyor belt to convey sleeves; the sleeve clamping and lifting mechanism includes a clamping and lifting frame and a sleeve clamping assembly that can be lifted and lowered on the clamping and lifting frame; the sleeve clamping assembly includes a crossbeam, a front clamping claw, a rear clamping claw, and a clamping claw opening and closing drive component; the front clamping claw and the rear clamping claw are symmetrically arranged and movably mounted on the crossbeam; the clamping claw opening and closing drive component is used to drive the front clamping claw and the rear clamping claw to make horizontal relative movements along the crossbeam, thereby gripping and releasing the sleeves.

[0007] Compared to manual handling or conveyor belt-based feeding of rubber sleeves, this application adds a rubber sleeve clamping and lifting mechanism. The front and rear clamping claws move relative to each other along the crossbeam to grab the rubber sleeves, and lift the rubber sleeves to the designed position by moving them up and down along the clamping and lifting frame. Therefore, when the winding drum of the forming device passes through the rubber sleeve, the center of the winding drum is aligned with the center of the rubber sleeve, thus ensuring the safety of the rubber sleeves during handling and the smooth progress of subsequent tape winding.

[0008] Preferably, the clamping and lifting frame is equipped with lifting guide rails and lifting cylinders facing the feeding conveyor belt. The lifting guide rails are symmetrically arranged on the left and right sides. The crossbeam is movably mounted on the lifting guide rails via "L"-shaped support plates. The fixed end of the lifting cylinder is mounted on the clamping and lifting frame via a support, and the telescopic end is connected to the "L"-shaped support plate, thereby driving the rubber sleeve clamping assembly to rise and fall along the lifting guide rails. The structure is interlocked, and the two lifting guide rails on the left and right sides ensure the stability of the lifting. The "L"-shaped support plate is equipped with movable blocks that can slide along the lifting guide rails. Accordion-style protective covers are installed between the upper and lower ends of the movable blocks and the upper and lower ends of the lifting guide rails on the "L"-shaped support plate to prevent dust from entering the gap between the movable blocks and the lifting guide rails, which would cause the lifting to be obstructed. The structural design is reasonable.

[0009] Further preferably, the front and rear clamping claws are both mounted on the crossbeam via a connecting member. The connecting member has a square sleeve at its right end. The crossbeam is equipped with a horizontal bidirectional lead screw and has a horizontal guide plate passing through the square sleeve on its left side. The clamping claw opening and closing drive is mounted at the front end of the crossbeam, and its output end has a drive wheel. The drive wheel and the driven wheel of the horizontal bidirectional lead screw are connected via a conveyor belt. The square sleeve has a groove to avoid the horizontal bidirectional lead screw and a nut that threads with the horizontal bidirectional lead screw is installed in the center. The clamping claws and rear clamping claws are located at different helical directions of the horizontal bidirectional lead screw. When the clamping claw opening and closing drive unit drives the horizontal bidirectional lead screw to rotate through the conveyor belt, the front clamping claws and rear clamping claws move relative to each other through the connecting parts. The structure is interlocked. A square sleeve is fitted onto the horizontal guide plate to achieve horizontal guidance. The nut of the square sleeve engages with the thread of the horizontal bidirectional lead screw. When the lead screw is driven to rotate, the square sleeve drives the corresponding front clamping claws and rear clamping claws to translate. Due to their different helical directions, they move relative to each other. The structure is ingeniously designed.

[0010] The left end of the connector is equipped with a clamping claw mounting platform facing inward. The front and rear clamping claws are both mounted on the clamping claw mounting platform in a figure-eight configuration using two single claws in a mirror image. The structure is reasonably designed. Each single claw includes a mounting component bolted to the clamping claw mounting platform, a connecting vertical plate mounted on the mounting component, and clamping components mounted on the connecting vertical plate at both ends. A vertical roller is mounted on the end of the clamping component near the rubber sleeve. When the clamping component squeezes inward to remove the rubber sleeve, the vertical roller rolls smoothly when it comes into contact with the rubber sleeve, avoiding direct hard contact friction that causes wear.

[0011] More preferably, the non-marking sidewall patching system includes a non-marking sidewall adhesive pressing machine and a conveyor line. The conveyor line includes, from left to right, a transition section, an upper sidewall patching section, a tire carcass flipping mechanism, a lower sidewall patching section, and a visual positioning section. The transition section, lower sidewall patching section, and visual positioning section all use a manually started and stopped conveyor belt mechanism to place and transport the tire carcass. The upper sidewall patching section and tire carcass flipping mechanism both use a manually started and stopped rotating roller mechanism to place and transport the tire carcass. The conveyor belt mechanism and the roller mechanism are each equipped with a corresponding tire carcass conveying drive.

[0012] The transition section is used to store tire blanks and improve patching efficiency. When the tire blank is automatically transported from the transition section to the upper tire side panel patching section, the pre-prepared film on the non-marking film presser is quickly applied to the upper tire side panel by a manual. Then, the roller mechanism of the upper tire side panel patching section is started to transport the tire blank to the tire blank turning mechanism. Then, the tire blank is manually pressed and turned over. Then, the pressing state is released, and the roller mechanism of the tire blank turning mechanism is started again to transport the tire blank to the lower tire side panel patching section. After the lower tire side panel film is applied manually, the conveyor belt mechanism of the lower tire side panel patching section is started to transport the tire blank to the vision positioning section. The steps are closely linked and the segmented process is reasonable.

[0013] More preferably, the tire blank turning mechanism includes a support base frame, a turning main frame, a liftable tire pressing frame, and a drive assembly. The roller mechanism of the tire blank turning mechanism adopts two rows of rollers respectively installed on the upper and lower inner sides of the turning main frame. The turning main frame is rotatably installed on the support base frame, and the liftable tire pressing frame is installed downward on the upper side of the turning main frame, so that it can pass through the gap between the rollers to press the tire blank. The drive assembly includes a turning drive component that drives the turning main frame to rotate and a tire pressing drive component that drives the liftable tire pressing frame to rise and fall. The visual positioning section is equipped with a laterally movable visual locator to detect the center coordinates of the tire blank after the sidewall patch is applied.

[0014] The visual positioning section is equipped with a laterally movable visual locator, which detects the center coordinates of the tire blank after the sidewall patch is applied. This facilitates automatic removal after the center coordinates of the tire blank are identified. The design is ingenious and has high practical value.

[0015] Further preferably, the tilting main frame is provided with side plates at both the front and rear, and the side plates are equipped with rotating shafts connected to the supporting base. The supporting base is equipped with bearings corresponding to the rotating shafts, so that the tilting main frame can be tilted and installed on the supporting base. A gear is installed at the outer end of the rotating shaft on the front side of the tilting main frame. The tilting drive is a worm gear reducer motor, and a lifting screw is installed at the output end. The bottom end of the lifting screw is provided with a rack that meshes with the gear. When the tilting drive drives the lifting screw to lift and lower, the rack drives the gear to rotate, thereby driving the tilting main frame to rotate. The structure is stable and the rotation is stable.

[0016] The tire blank turning mechanism uses a servo motor for the tire blank conveying drive component corresponding to the roller mechanism, and is installed on the front side plate of the turning main frame. The front side of the support base is provided with a semi-circular arc-shaped drag chain mounting groove and equipped with a drag chain, thereby providing space for the wiring harness of the tire blank conveying drive component and the turning drive component to move and be placed as the turning main frame turns. The installation is reasonable and effectively avoids the wiring harness from getting tangled and affecting the operation.

[0017] Further preferably, the liftable tire pressing frame includes a pressure plate, a vertical connecting rod, and a connecting top plate. Two pressure plates are used and located within the tilting main frame. The front and rear ends of each pressure plate are connected to the connecting top plate via a vertical connecting rod extending outwards from the tilting main frame. The front and rear ends of the connecting top plate extend outwards to the side plates of the tilting main frame. The tire pressing drive is a cylinder, with its fixed end mounted on the side plate of the tilting main frame and its telescopic end vertically upwards connected to the front and rear ends of the connecting top plate. When the telescopic end of the tire pressing drive drives the connecting top plate to rise or fall, the pressure plate is raised or lowered via the vertical connecting rod. The upper tire side panel is equipped with a weighing lifting platform and a weighing lifting drive for raising and lowering the weighing lifting platform. A support rod is provided at the top of the weighing lifting platform corresponding to the gap in the roller mechanism. Thus, when the weighing lifting drive drives the weighing lifting frame to rise, the support rod passes through the gap in the roller mechanism to lift the tire blank for weighing. The structural design is reasonable.

[0018] More preferably, the visual locator is mounted on the side of the conveyor belt mechanism of the visual positioning section via a locator mounting bracket. The locator mounting bracket includes a base frame, an upper mounting frame, and a drive cylinder. The top of the base frame is provided with a guide rail. The movable end of the upper mounting frame is mounted on the guide rail via a slider, and the positioning end extends horizontally to directly above the conveyor belt mechanism. The drive cylinder is used to drive the upper mounting frame to move laterally along the base frame. The visual locator is mounted downwards on the positioning end of the upper mounting frame and can correspond vertically with the tire blank, thereby detecting the center coordinates of the tire blank. The structure is ingeniously designed.

[0019] The beneficial effects of this invention are:

[0020] (1) Compared with the current lack of intelligent molding production system for non-marking solid tires and the unreasonable spatial layout and high equipment cost of existing solid tire production lines, this application adds a non-marking tread adhesive wrapping system for tire sidewall patching, which meets the requirements of non-marking tires and is reasonably planned.

[0021] (2) The rubber sleeve feeding system, base rubber pressing machine, middle rubber pressing machine, quick drum changing system, and non-marking film sidewall patching system are arranged clockwise around the six-axis robot 1. The quick drum changing system, non-marking film sidewall patching system, transition table, non-marking tread pressing machine, and finished product weighing and unloading system are arranged clockwise around the six-axis robot 2. This is equivalent to circling around the six-axis robot 1 and the six-axis robot 2. This makes full use of the 360-degree rotation feature of the movable end of the six-axis robot, rationally plans the equipment layout, has a high space utilization rate, and makes it convenient for the six-axis robot to operate flexibly in the central area without being disturbed by other equipment.

[0022] In summary, this invention has the advantages of ingenious and novel layout, avoidance of equipment waste, reduction of production line setup costs, and economic value. Attached Figure Description

The non-marking tread adhesive winding system 5 consists of a six-axis robot 2 51, a transition table 52, and a non-marking tread pressing machine 53. The quick drum changing system 1, the right end of the non-marking film sidewall bonding system 4, the transition table 52, the non-marking tread pressing machine 53, and the finished product weighing and unloading system 8 are arranged clockwise around the six-axis robot 2 51, so that the six-axis robot 1 31 can take the tire blank 7 from the right end of the non-marking film sidewall bonding system 4, temporarily place it on the transition table 52, readjust it to the center, and then wind the tread adhesive through the non-marking tread pressing machine 53 before placing it in the finished product weighing and unloading system 8.

[0035] Figure 2 A schematic diagram of the quick drum changing system is shown.

[0036] The quick drum changing system 1 consists of two forming units 12 placed on the mounting platform 11, and the forming drums 121 on the two forming units 12 correspond to two sizes of non-marking solid tires, namely 8-inch to 14-inch and 15-inch to 20-inch. The two quick drum changing systems 1 can be used by six-axis robot 1 31 and six-axis robot 2 51 to automatically change the forming unit 12 corresponding to the tire size. The transition platform 52 is used to temporarily place the tire blank 7 for six-axis robot 2 51 to readjust and center for picking.

[0037] Figures 3-6 A schematic diagram of the rubber sleeve feeding system and its components is shown.

[0038] The rubber sleeve feeding system 2 consists of a feeding conveyor belt 21 and a rubber sleeve clamping and lifting mechanism located at the right end of the feeding conveyor belt 21. The feeding conveyor belt 21 is installed on the main conveyor frame 211 and is equipped with a conveying drive component 212 that drives the feeding conveyor belt 21 to convey the rubber sleeves 6. The rubber sleeve clamping and lifting mechanism consists of a clamping and lifting frame 22 and a rubber sleeve clamping assembly that can be lifted and lowered on the clamping and lifting frame 22. The rubber sleeve clamping assembly consists of a crossbeam 23, a front clamping claw 24, a rear clamping claw 25, and a clamping claw splitting and engaging drive component 26. The front clamping claw 24 and the rear clamping claw 25 are symmetrically arranged and movably installed on the crossbeam 23. The clamping claw splitting and engaging drive component 26 is used to drive the front clamping claw 24 and the rear clamping claw 25 to move horizontally relative to each other along the crossbeam 23, thereby gripping and releasing the rubber sleeves 6.

[0039] The clamping and lifting frame 22 is provided with a lifting guide rail 221 and a lifting cylinder 222 facing the feeding conveyor belt 21. The lifting guide rail 221 is symmetrically arranged on the left and right. The crossbeam 23 is movably installed on the lifting guide rail 221 through the "L"-shaped support plate 231. The fixed end of the lifting cylinder 222 is installed on the clamping and lifting frame 22 through the support, and the telescopic end is connected to the "L"-shaped support plate 231, so as to push the rubber sleeve clamping assembly to rise and fall along the lifting guide rail 221.

[0040] The “L”-shaped support plate 231 is equipped with a movable block that can slide along the lifting guide rail 221. The upper and lower ends of the movable block corresponding to the “L”-shaped support plate 231 and the upper and lower ends of the lifting guide rail 221 are both equipped with accordion-style protective covers.

[0041] Both the front clamping jaw 24 and the rear clamping jaw 25 are mounted on the crossbeam 23 via a connector 27. The right end of the connector 27 is provided with a square sleeve 271. The crossbeam 23 is equipped with a horizontal bidirectional lead screw and has a horizontal guide plate 232 that passes through the square sleeve 271 on the left side. The clamping jaw opening and closing drive 26 is installed at the front end of the crossbeam 23 and has a drive wheel at the output end. The drive wheel is connected to the driven wheel of the horizontal bidirectional lead screw via a conveyor belt. The square sleeve 271 has a groove 271a to avoid the horizontal bidirectional lead screw and a nut that engages with the thread of the horizontal bidirectional lead screw is installed in the center. The front clamping jaw 24 and the rear clamping jaw 25 are located at different helical positions of the horizontal bidirectional lead screw. When the clamping jaw opening and closing drive 26 drives the horizontal bidirectional lead screw to rotate via the conveyor belt, the front clamping jaw 24 and the rear clamping jaw 25 move relative to each other through the connector 27.

[0042] The left end of the connector 27 is inwardly mounted with a clamping claw mounting platform 272. The front clamping claw 24 and the rear clamping claw 25 are both mounted on the clamping claw mounting platform 272 in a figure-eight shape using two single claws 29. Each single claw 29 consists of a mounting part 291 bolted to the clamping claw mounting platform 272, a connecting vertical plate 292 mounted on the mounting part 291, and clamping parts mounted on the connecting vertical plate 292 at both ends. A vertical roller 293 is mounted on the end of the clamping part near the rubber sleeve 6.

[0043] Figures 7-10 A schematic diagram of the non-marking film sidewall patch system and its components is shown.

[0044] The non-marking sidewall patching system 4 consists of a non-marking sidewall adhesive pressing machine 48 and a conveyor line. The conveyor line consists of a transition section 45, an upper sidewall patching segment 41, a tire carcass flipping mechanism 42, a lower sidewall patching segment 43, and a visual positioning section 44 arranged sequentially from left to right. The transition section 45, the lower sidewall patching segment 43, and the visual positioning section 44 all use a manually started and stopped conveyor belt mechanism 46 to place and transport the tire carcass 7. The upper sidewall patching segment 41 and the tire carcass flipping mechanism 42 both use a manually started and stopped rotating roller mechanism 47 to place and transport the tire carcass 7. The conveyor belt mechanism 46 and the roller mechanism 47 are both equipped with corresponding tire carcass conveying drive components.

[0045] The tire blank flipping mechanism 42 consists of a support base 423, a flipping main frame 421, a liftable tire pressing frame 422, and a drive assembly. The roller mechanism 47 of the tire blank flipping mechanism 42 uses two rows of rollers respectively installed on the upper and lower inner sides of the flipping main frame 421. The flipping main frame 421 is rotatably installed on the support base 423. The liftable tire pressing frame 422 is installed downward on the upper side of the flipping main frame 421, so that it can pass through the gap between the rollers to press the tire blank 7. The drive assembly consists of a flipping drive 427 that drives the flipping main frame 421 to rotate and a tire pressing drive 424 that drives the liftable tire pressing frame 422 to rise and fall. The visual positioning section 44 is equipped with a transversely movable visual locator 441, which detects the center coordinates of the tire blank 7 after the sidewall patch is applied.

[0046] The main tilting frame 421 has side plates at both the front and rear. The side plates are equipped with rotating shafts that are connected to the support base frame 423. The support base frame 423 is equipped with bearings corresponding to the rotating shafts, so that the main tilting frame 421 can be tilted and installed on the support base frame 423. A gear 425 is installed at the outer end of the rotating shaft at the front of the main tilting frame 421. The tilting drive component 427 is preferably a worm gear reducer motor, and a lifting screw 427a is installed at the output end. The bottom end of the lifting screw 427a is provided with a rack that meshes with the gear 425. When the tilting drive component 427 drives the lifting screw 427a to rise and fall, the rack drives the gear 425 to rotate, thereby driving the main tilting frame 421 to rotate.

[0047] The tire rollover mechanism 42 preferably adopts a double-button start-up rollover mechanism. A brake disc 428 is installed on the outer end of the gear 425, and a pneumatic safety brake 429 is provided to achieve emergency braking when power or air supply is interrupted.

[0048] The tire blank turning mechanism 42 uses a servo motor for the tire blank conveying drive corresponding to the roller mechanism 47, and is installed on the front side plate of the turning main frame 421; the front side of the support base 423 is provided with a semi-circular arc-shaped drag chain mounting groove and equipped with a drag chain 426, thereby providing a movable mounting space for the wiring harness of the tire blank conveying drive and the turning drive 427 as the turning main frame 421 turns.

[0049] The liftable tire press frame 422 consists of a pressure plate 422a, a vertical connecting rod 422b, and a connecting top plate 422c. Two pressure plates 422a are located within the tilting main frame 421, and the front and rear ends of each pressure plate 422a are connected to the connecting top plate 422c via a vertical connecting rod 422b extending outwards from the tilting main frame 421. The front and rear ends of the connecting top plate 422c extend outwards to the side plates of the tilting main frame 421. The tire press drive component 424 is a cylinder, with its fixed end mounted on the side plate of the tilting main frame 421 and its telescopic end vertically upwards and connected to the front of the connecting top plate 422c. The rear end is connected so that when the tire pressing drive 424 drives the connecting top plate 422c to rise or fall, the vertical connecting rod 422b drives the pressure plate 422a to rise or fall. The upper tire side panel segment 41 is equipped with a weighing lifting platform 411 and a weighing lifting drive 412 that drives the weighing lifting platform 411 to rise or fall. The top of the weighing lifting platform 411 is provided with a support rod 413 corresponding to the gap of the roller mechanism 47. So when the weighing lifting drive 412 drives the weighing lifting frame 411 to rise, the support rod 413 passes through the gap of the roller mechanism 47 to lift the tire blank 7 for weighing.

[0050] The visual locator 441 is mounted on the side of the conveyor belt mechanism 46 of the visual positioning section 44 via a locator mounting bracket. The locator mounting bracket consists of a base frame 442, an upper mounting frame 443, and a drive cylinder. The top of the base frame 442 is provided with a guide rail. The movable end of the upper mounting frame 443 is mounted on the guide rail via a slider, and the positioning end extends horizontally to directly above the conveyor belt mechanism 46. The drive cylinder is used to drive the upper mounting frame 443 to move laterally along the base frame 442. The visual locator 441 is mounted downwards on the positioning end of the upper mounting frame 443 and can correspond vertically with the tire blank 7, thereby detecting the center coordinates of the tire blank 7.

[0051] The finished product weighing and unloading system 8 consists of a weighing platform 81 for weighing the tire blank 7 and an unloading gantry robot mechanism 82 for taking away qualified tire blanks 7. The minimum gap between the unloading gantry robot mechanism 82 and the weighing platform 81 is 500mm, which ensures that personnel can wrap the edges through the corner.

[0052] A method for intelligent molding and production of seamless solid tires, the specific implementation steps of which are as follows:

[0053] Step S1: Construct the above-mentioned seamless solid tire intelligent molding production line. The six-axis robot 31 automatically installs the corresponding molder 12 on the quick drum changing system 1 according to the tire production specifications. The manual staff scans the rubber sleeve 6 and places it one by one on the rubber sleeve feeding system 2 for automatic transmission to the designed position and lifting. After receiving the instruction, the six-axis robot 31 takes away the rubber sleeve 6 and winds it with base glue and middle glue in sequence through the base glue pressing machine 32 and the middle glue pressing machine 33.

[0054] Step S2: After completing the middle adhesive wrapping, the six-axis robot 31 places the tire blank 7 in the transition section 45. The light spot switch detects the presence of the tire blank 7 and starts the transition section 45 to transport it to the upper tire sidewall patch segment 41. Then, the manual person quickly applies the pre-prepared adhesive sheet from the non-marking tire sidewall adhesive press 48 to the upper tire sidewall of the tire blank 7. Then, the manual person starts the upper tire sidewall patch segment 41 to transport the tire blank 7 to the tire blank flipping mechanism 42. The manual person starts the tire blank flipping mechanism 42 with two buttons to flip the tire blank 7 180°. Then, the manual person starts the transport to the lower tire sidewall patch segment 43 to apply the other tire sidewall adhesive sheet to the tire blank 7. Then, the manual person starts the lower tire sidewall patch segment 43 to transport the tire blank 7 to the vision positioning segment 44 for vision positioning and transmits the center coordinates of the tire blank 7 to the six-axis robot 51.

[0055] Step S3: The six-axis robot 51 installs the corresponding model of the molding machine 12, and after receiving the center coordinates of the tire blank 7, it accurately picks up the tire blank 7 and places it on the transition table 52 to pick it up again in the center. Then, after the tire tread is wrapped with tire tread adhesive by the non-marking tire tread press 53, it is placed on the weighing table 81.

[0056] Step S4: When the weight of the tire blank 7 on the weighing platform 81 meets the requirements, the unloading gantry robot mechanism 82 takes away the tire blank 7. When the weight of the tire blank 7 exceeds the deviation range, it is corrected manually. At the same time, the finished product weighing and unloading system 8 will feed back the correction value to the next tire blank 7 when the tread is wound for automatic correction.
