Description

Technical Field

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

[0002] In existing technology, there are two ways to form solid tires: one is, such as Figure 1 As shown, a circular overhead track trolley allows the tire blank to flow in each process, thereby sequentially wrapping the base rubber, middle rubber, and tread rubber onto the tire blank; another method, such as... Figure 2 As shown, a shuttle-type ground track trolley is used to allow the tire blank to flow in each process, thereby realizing the sequential winding of base rubber, middle rubber, and tread rubber on the tire blank.

[0003] The above methods all have the following problems:

[0004] 1) The entire equipment does not have an automatic measurement function. For solid tires of different specifications, the width and length of the rubber strips need to be measured manually. Therefore, it requires skilled workers and thus increases labor costs.

[0005] 2) The entire production line involves a high level of worker participation, including manual work such as preparing spare tire blanks, counterweighting, length and width determination, and weighing. This results in low production efficiency, and manual operation is prone to errors, leading to high product precision. Summary of the Invention

[0006] This invention proposes an intelligent molding production system for solid tires, which can effectively realize fully automated rubber winding of solid tires, thereby reducing manual intervention in the production process, improving production efficiency, and increasing the yield rate.

[0007] Therefore, the technical solution adopted by the present invention is as follows: a solid tire intelligent molding production system, including multiple six-axis robots and multiple pressing machines capable of pressing base rubber, middle rubber and tread rubber into corresponding thicknesses. Each six-axis robot is equipped with a forming device for picking up and rotating and winding the tire blank. A tire blank transfer detection device is set between two adjacent six-axis robots, and each six-axis robot can pick up or put the tire blank from the corresponding tire blank transfer detection device. The tire blank transfer detection device is used to temporarily store the tire blank, weigh the weight of the rubber wrapped in the previous process, and determine the joint position after the rubber wrapped in the previous process. The six-axis robot can carry the forming device to wind the base rubber, middle rubber or tread rubber at the outlet end of the corresponding pressing machine, and each pressing machine is equipped with a width and length fixing device that can determine the length and width of the rubber wrapped on the tire blank as needed.

[0029] 2) By setting up a tire carcass transfer detection device with detection and joint detection functions, the base rubber, intermediate rubber and tread rubber can be detected in time after the winding is completed to ensure that the winding meets the standards. At the same time, the joint position can be detected in time, so that the next winding can start from the position and ensure that adjacent rubbers can be accurately wound. This reduces the number of workers involved and improves efficiency and finished product qualification rate.

Detailed Implementation

[0049] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0050] like Figure 1-17 As shown, a solid tire intelligent molding production system mainly consists of multiple six-axis robots 100 arranged according to the process and multiple pressing machines 200 that can press the base rubber, middle rubber and tread rubber into corresponding thicknesses. Each six-axis robot 100 is equipped with a molding device 300 for picking up and rotating and winding the tire blank. A tire blank transfer detection device 400 is provided between two adjacent six-axis robots 100.

[0051] Both the six-axis robot and the tablet press utilize existing technology, and each tablet press is equipped with a corresponding extruder, which is also based on existing technology. A material conveyor belt for moving the rubber compound is installed between the tablet press and the extruder. The six-axis robot, in conjunction with the forming device, picks up, places, and wraps the tire blank with rubber. The tire blank transfer and detection device 400 is used to temporarily store the tire blank, weigh the rubber compound wrapped in the previous process, and determine the joint position after the previous process. To ensure that the rubber compound wrapped on the tire blank meets the design specifications, each tablet press 200 is equipped with a width and length fixing device 500 at its outlet end, which can determine the length and width of the rubber compound wrapped on the tire blank as needed.

[0052] The specific structure of the molding device 300 includes a mounting base 310 for mounting on a six-axis robot 100. A molding component 330 is provided on the mounting base 310 via a molding moving component 320. The molding moving component is used to drive the molding component to move back and forth. During the glue wrapping process, as the wrapping diameter increases, the molding drum is driven to move backward via the molding moving component to ensure stable pressure throughout the glue wrapping process.

[0053] The molding assembly 330 includes a molding drum 340 and a molding expansion cylinder 331 for inflating or contracting the molding drum 340. The output end of the molding expansion cylinder 331 is connected to the molding drum 340. The molding expansion cylinder 331 is mounted on the molding moving assembly 320 via a molding bracket 332. One end of the molding drum 340 is rotatably mounted on a molding seat 333, which is also mounted on the molding moving assembly. The molding drum is prior art and will not be described in detail here. By extending and retracting the molding expansion cylinder, the molding drum can be inflated or contracted, allowing the molding drum to engage with the embryo from the inside or separate from the embryo. This facilitates the movement of the six-axis robot or the placement of the embryo.

[0054] The molding moving assembly 320 includes a molding base plate 322 mounted on a mounting base 310 via a molding connecting plate 321. A molding drum moving cylinder 323 is mounted on the molding base plate 322. A molding moving block 324 is mounted at the output end of the molding drum moving cylinder 323. A first guide rail slider assembly 325 is mounted between the molding moving block 324 and the molding base plate 322. A molding seat 333 and a molding bracket 332 are both mounted on the molding moving block 324. Preferably, a molding distance sensor for measuring the movement distance of the molding drum 300 under the action of the molding moving assembly 320 is mounted on the mounting base 310 or the molding connecting plate 321, which facilitates stable control of the molding assembly.

[0055] The forming device also includes a brake 350 to ensure that the forming drum 340 can only rotate during winding. A brake disc 334 is fitted over the forming drum 340 near its connection with the forming expansion cylinder 331. The brake 350 is mounted on the forming support 332 and clamps the brake disc 334. Because the forming drum is a free roller, the cooperation of the brake and brake disc effectively prevents the forming drum from rotating when picking up the tire blank. This ensures that the joint position after the previous winding process remains unchanged, thus guaranteeing accurate alignment during subsequent winding.

[0056] To facilitate the connection of wires and air pipes within the molding machine, an air-mounted connector 360 is provided between the mounting base 310 and the molding moving assembly 320 to facilitate electrical connection between the molding machine 300 and the six-axis robot 100.

[0057] The molding machine operates as follows: Initially, the molding drum is in a contracted state, and the molding moving component moves the molding component to a position away from the mounting base, while the brake clamps the brake disc. During operation, the six-axis robot drives the molding machine to the corresponding position, allowing the molding drum to extend into the corresponding tire blank. Then, the molding expansion cylinder operates to expand the molding machine, thereby clamping the tire blank from the inside. Next, the six-axis robot moves to the position where adhesive wrapping is required, and then the brake releases the brake disc. Through the molding drum push cylinder, the molding drum containing the tire blank is pushed against the adhesive application roller of the upper pressing machine. The molding drum then rotates passively, at which point the film head cut by the fixed-length blade adheres to the adhesive sleeve or tire blank, thus achieving adhesive wrapping.

[0058] During the adhesive wrapping process, as the tire blank diameter increases, the forming moving component moves the forming drum towards the mounting base to ensure the adhesive wrapping pressure. After the adhesive wrapping is completed, the brake clamps the brake disc, and then the six-axis robot moves the forming drum to the position where the tire blank is placed. The forming expansion cylinder then operates, causing the forming drum to contract, thereby separating the tire blank from the forming drum for the next operation.

[0059] The tire blank transfer detection device 400 includes a detection base 410, a rotating assembly 420 mounted on the detection base 410, a weighing assembly 430 mounted on the rotating assembly 420 for weighing the weight of the placed workpiece, and a variable diameter disc assembly 440 mounted on the weighing assembly 430 for placing a portion of the processed tire blank. Simultaneously, the detection base 410 is also equipped with a first detection sensor 460 for detecting whether a tire blank has been placed, and a second detection sensor 470 for detecting the joint of the wound film, both mounted on different detection columns. The first detection sensor is a laser reflection sensor, and the second detection sensor is a laser rangefinder sensor.

[0060] The variable diameter plate assembly 440 includes two placement platforms 441 arranged opposite each other for placing tire blanks. The placement platforms 441 are mounted on the weighing assembly 430 via the variable diameter assembly. The variable diameter assembly includes a servo variable diameter motor 443, and a variable diameter lead screw 445 is provided at the output end of the servo variable diameter motor. Each placement platform 441 has a variable diameter nut 446 at its bottom that can be screwed to the variable diameter lead screw 445. The helical arrangement of the two variable diameter nuts 446 is opposite to that of the variable diameter lead screw 445. A second guide rail slider assembly 447 is provided between the placement platforms 441 and the weighing assembly 430 to facilitate movement. When the servo variable diameter motor is working, it drives the variable diameter lead screw to rotate. Through the cooperation of the variable diameter lead screw and the variable diameter nut, the two placement platforms can move in opposite directions, allowing the placement platforms to be used for placing tire blanks of different diameters.

[0061] Preferably, the placement table 441 includes an upper plate and a lower plate spaced apart, and the upper plate and the lower plate are connected by a connecting column, so that the forming drum 340 does not come into contact with the variable diameter plate assembly when picking up or putting down the tire blank, which can effectively prevent the side of the tire blank from being scratched when placing or taking it out, thereby ensuring the processing quality.

[0062] The weighing assembly 430 includes a variable diameter base plate 431 disposed at the bottom of the variable diameter disc assembly 440 and a weighing base plate 432 disposed on the rotating assembly 420. A weighing moving plate 433 is disposed between the variable diameter base plate 431 and the weighing base plate 432. A weighing scale 439 is disposed on the weighing moving plate. A weighing lifting cylinder is disposed on the weighing base plate 432, and the output end of the weighing lifting cylinder is disposed on the weighing moving plate 433. That is, the operation of the weighing lifting cylinder can drive the weighing moving plate and the weighing scale to move up and down, so as to realize the contact or separation of the weighing scale with the variable diameter base plate. When the weighing scale is in contact with the variable diameter base plate, it can be used to weigh the overall weight including the variable diameter base plate and the variable diameter disc assembly, so as to realize the weighing of the tire after the tire blank is placed. When the weighing scale is separated from the variable diameter base plate, since there will be vibration when the tire blank is placed, in order to protect the weighing scale, the weighing scale is separated from the variable diameter base plate when weighing is not needed.

[0063] To ensure the guiding of the weighing moving plate and the weighing scale's vertical movement, four rectangularly distributed support guide columns 435 are provided between the variable diameter base plate 431 and the weighing base plate 432. The lower ends of the support guide columns 435 are fixed to the weighing base plate 432, and the upper ends of the support guide columns 435 abut against the variable diameter base plate 431. A support sleeve 436 is provided on the bottom surface of the variable diameter base plate 431 for the support guide columns 435 to extend into. At the same time, a sliding sleeve 437 is provided on the weighing moving plate 433 at the position of the support guide columns 435, which can slide vertically relative to the support guide columns 435. When the weighing moving plate 433 is in its upward position under the action of the weighing lifting cylinder, the sliding sleeve can lift the support sleeve, causing the upper end of the support guide column to separate from the variable diameter base plate, so that the variable diameter base plate is supported by the weighing scale, thereby ensuring the weighing effect. At the same time, the support guide column is located inside the support sleeve.

[0064] To ensure the stability of the weighing moving plate's vertical movement, a first buffer 438 for displaying the moving distance of the weighing moving plate 433 is provided between the weighing moving plate 433 and the weighing base plate 432. Four first buffers 438 are arranged in a rectangular shape. Simultaneously, an upper buffer 4390 is provided on the variable-diameter base plate 431, passing through the weighing moving plate 433 and abutting against the lower buffer 4391. The lower buffer 439 is located on the weighing base plate 432. The rotating assembly includes a rotating disk 421 and a rotating base 422. The rotating base 422 is located on the detection base 410. The fixed end of the rotating disk 421 is located on the rotating base 422, and the rotating end of the rotating disk 421 is located on the weighing assembly 430, specifically on the weighing base plate of the weighing assembly. The rotating disk is existing technology.

[0065] The tire blank transfer detection device works as follows: When the first detection sensor detects that a tire blank has been placed, the weighing lifting cylinder drives the weighing moving plate and the weighing scale to move upward, so that the variable diameter base plate is supported by the weighing scale. Then, the weight of the placed tire blank is read by the weighing scale and compared with the process standard weight. If the weight exceeds the tolerance, the system will adjust the upstream and downstream processes to ensure that the weight of the finished product meets the process requirements. Then, the rotating disk drives the entire weighing assembly and the variable diameter assembly to rotate. The second detection sensor detects the variable diameter point at the end of the film winding and automatically finds the film joint after the previous process has finished winding, so that the next process can continue winding along the joint.

[0066] The tire blank transfer detection device of this application realizes the weight detection after glue wrapping through the weighing component, and can transmit the deviation to the upper and lower wrapping points for easy closed-loop adjustment; at the same time, it is provided with a variable diameter plate component for placing tire blanks of different sizes for weighing, and the forming hanger on the forming device can smoothly pass through the inner diameter of the tire blank vertically, and put down or grab the tire blank without contacting the variable diameter plate.

[0067] The length and width fixing device 500 includes a length fixing component 510 for determining the length of the wrapping adhesive and a width fixing component 520 for determining the width of the wrapping adhesive. The width fixing component 520 is located between the length fixing component 510 and the corresponding tablet press 200. Both the length fixing component 510 and the width fixing component 520 are mounted on the mounting base 540 via a length and width fixing moving component 530. The length and width fixing moving component 530 is used to move the length fixing component 510 and the width fixing component 520 closer to or further away from the tablet press 200, so that the length and width fixing components can automatically adjust their positions according to the position of the adhesive application roller on the tablet press, ensuring that the length fixing component and the width fixing component can cut the adhesive material located on the adhesive application roller on the tablet press. Preferably, a distance detection sensor is provided on the mounting base 540 to detect the movement distance of the length fixing component 510 and the width fixing component 520 under the action of the length and width fixing moving component 530. To prevent the fixed length and width component from cutting the rubber material when not in operation, an anti-displacement clamping component is provided at the end of the mounting base 540 away from the tablet press, which can clamp the fixed length and width moving component 530, and the anti-displacement clamping component adopts existing technology.

[0068] The length-fixing component 510 includes a length-fixing height-increasing seat 511 disposed on the length-fixing width-moving component 530. A length-fixing seat 512 is disposed on the length-fixing height-increasing seat 511, and the upper end of the length-fixing seat 512 is obliquely upward on the side facing the tablet press 200. A length-fixing adjustment component is disposed on the length-fixing seat 512 via the length-fixing moving component. The length-fixing adjustment component enables the length-fixing cross-cutting blade to be applicable to the rubber material, thereby ensuring the cutting of the wound rubber material. The length-fixing moving component enables the length-fixing cross-cutting blade to move to the corresponding stop position when the rubber material needs to be cut, and cut the rubber material.

[0069] The length adjustment assembly includes two length adjustment shafts 513 spaced apart and extending along the length adjustment seat 512. The two ends of the length adjustment shafts 513 are mounted on the length movement assembly via corresponding length adjustment seats 514. Each length adjustment shaft 513 is slidably provided with a length adjustment block 515. The two length adjustment blocks 515 are connected to a length mounting shaft 517 via a length connecting block 516. A length adjustment spring is sleeved on the length adjustment shaft 513 and is located between the length adjustment block 515 and the length adjustment seat 514 at the end away from the tablet press. The length mounting shaft 517 is located between the two length adjustment blocks 515 and is located on the side closer to the tablet press. A length cross-cutting blade 518 facing the tablet press is provided on the length mounting shaft 517 via a detachable assembly.

[0070] The fixed-length moving assembly includes a fixed-length moving plate 519, a crank-slider mechanism for moving the fixed-length moving plate 519 is provided between the fixed-length moving plate 519 and the fixed-length base 512, and a third guide rail assembly is provided between the fixed-length moving plate 519 and the fixed-length base 512. The detachable assembly includes a pressure plate, and a mounting step corresponding to the pressure plate is provided on the fixed-length shaft, through which the fixed-length cross-cutting blade is mounted on the mounting step.

[0071] The width-fixing component 520 includes a width-adjustable component mounted on the length-width-motion component 530. This width-adjustable component enables the cutting of adhesive materials of different widths. The width-adjustable component has two width-moving blocks 531 that can move relative to or towards each other. Each width-moving block 531 is equipped with a width-cutting component for achieving fixed-width cutting of the adhesive. The width-adjustable component employs a motor-screw mechanism and is equipped with a width detection sensor for detecting the distance between the two width-moving blocks, thereby obtaining the distance between the two width-moving blocks, i.e., the width of the adhesive material.

[0072] The width cutting assembly includes a width base 532 mounted on a width moving block 531, with the upper end of the width base 532 tilted upwards towards the tablet press. A width telescopic cylinder 533 is mounted on the width base 532, and a width cutter holder 534 is mounted on the width telescopic cylinder 533. A width shaft 536 is mounted on the width cutter holder 534 via a width mounting sleeve 535, and a circular cutter 537 is mounted at one end of the width shaft 536. During the adhesive wrapping process, when the thickness of the adhesive on the tablet press's adhesive roller decreases, the circular cutter extends accordingly through the operation of the width telescopic cylinder, thereby ensuring stable control of the adhesive wrapping width.

[0073] When the width and length fixing device is working, the width fixing component adjusts the distance between the two circular cutters according to the input rubber material width. Then, the length and width fixing moving component drives the length fixing component and the width fixing component to move to the glue application roller 210 near the tablet press. After the tire blank is moved into place, the circular cutter cuts into the rubber material on the glue application roller under the action of the width telescopic cylinder, realizing the width adjustment of the rubber material. When the set length is reached, the crank slider mechanism works, causing the length fixing cross cutter to move towards the glue application roller to cut the rubber material and then retract.

[0074] Preferably, the system also includes an automatic feeding device 800 for loading the tire blank. The automatic feeding device 800 includes a material handling tensioner 820 mounted on a three-axis moving assembly 810. The material handling tensioner 820 has an unfolding and retracting function, allowing it to secure the rubber sleeve from the inside. A trolley fixing assembly 830 for fixing the automatic trolley is provided on the bottom surface inside the three-axis moving assembly 810. A rubber sleeve positioning assembly 840 for automatically centering the rubber sleeve is provided on the right side of the three-axis moving assembly 810. The automatic trolley is used to transport the rubber sleeve from the previous process to the loading point of the rubber wrapping process. The automatic trolley is an AGV (Automated Guided Vehicle) trolley, a technology already in use.

[0075] The three-axis moving assembly 810 includes a left-right moving assembly 811 set on columns spaced apart on the left and right sides, a front-back moving assembly 812 set on the left-right moving assembly 811, a vertical moving assembly 813 set on the front-back moving assembly 812, and a material take-up tensioner 820 set on the vertical moving assembly 813. To ensure the accuracy of the moving position, the left-right moving assembly, the front-back moving assembly, and the vertical moving assembly can adopt a gear and rack structure or a high-precision linear guide structure.

[0076] The material handling telescoping device 820 includes a material handling base 821 mounted on a three-axis moving assembly 810 and a contact member 822 that extends vertically to contact the inside of the rubber sleeve. A fixed cylinder 823 extending vertically is mounted on the bottom surface of the material handling base 821. A sliding cylinder 824 is slidably mounted inside the fixed cylinder 823. A material handling telescoping cylinder 825 is mounted on the material handling base 821. The telescoping end of the material handling telescoping cylinder 825 passes through the material handling base 821 and is mounted on the upper end of the sliding cylinder 824. At least three contact members 822 are provided, and the contact members 822 are connected to the fixed cylinder 823 through a telescoping structure.

[0077] Specifically, the telescopic structure includes two sliding blocks 826 and two fixed blocks 827 sleeved outside the fixed cylinder 823. The sliding blocks 826 can slide up and down relative to the fixed cylinder 823. The sliding blocks 826 and the fixed blocks 827 are staggered vertically. Each contact member 822 has a long connecting rod 828 hinged to its upper and lower ends. The other end of each long connecting rod 828 is hinged to the sliding block 826. A short connecting rod 829 is hinged to the middle of the long connecting rod 828. The other end of the short connecting rod 829 is hinged to the fixed block 827. A limiting groove is provided outside the fixed cylinder 823. A moving groove is provided on the sliding cylinder 824. A transmission rod 8261 is provided on the sliding block 826. One end of the transmission rod 8261 passes through the limiting groove and extends into the moving groove.

[0078] When the material handling telescopic cylinder is working, it can drive the sliding cylinder to move up and down. Through the transmission rod, the sliding block can move up and down, thereby driving one end of the long connecting rod to move up and down. Through the short connecting rod, the contact parts can be expanded or contracted.

[0079] The trolley fixing assembly 830 includes a limiting rod 831 for limiting the position of the automatic trolley and a clamping assembly for fixing the automatic trolley 900. Two limiting rods 831 extending to the left and right are provided at the wheels of each row of automatic trolleys. A guide section is provided on the left side of the limiting rod 831 to facilitate the entry of the automatic trolley. The clamping assembly is located at the right end of the limiting rod 831.

[0080] The clamping assembly includes a limiting seat 832 and a clamping seat 833. A clamping cylinder 834 is disposed on the clamping seat 833, and a clamping block 835 is disposed on the clamping cylinder 834. When the automatic carriage 900 moves into position, the clamping cylinder 834 operates, causing the clamping block 835 to change from a horizontal state to a vertical state, thereby clamping the automatic carriage 900 onto the clamping seat 833 from the left side. Preferably, both the clamping seat 833 and the clamping block 835 are provided with buffer blocks 836. The connection between the clamping cylinder and the clamping block is prior art.

[0081] The rubber sleeve positioning assembly 840 includes a rubber sleeve positioning seat 841. A bidirectional moving assembly 842 extends forward and backward on the rubber sleeve positioning seat 841. Two bidirectional moving blocks 843 are provided on the bidirectional moving assembly 842, and the two bidirectional moving blocks 843 can move towards each other synchronously or in opposite directions. Each bidirectional moving block 843 is provided with a centering clamping assembly that can clamp the rubber sleeve. The bidirectional moving assembly can adopt the motor screw structure in the prior art, and the screw is provided with threads with opposite directions at both ends.

[0082] The centering clamping assembly includes clamping seats 844 vertically arranged on corresponding bidirectional moving blocks 843. Each clamping seat 844 has two sets of moving shafts 845 extending forward and backward at left and right intervals, and the moving shafts 845 on the two clamping seats 844 are arranged opposite each other. A clamping moving block 846 is provided at the end of each set of moving shafts 845 away from the corresponding clamping seat, and the clamping moving block 846 can move back and forth on the corresponding moving shaft 845. An adjusting spring 847 is sleeved on the moving shaft 845 and located between the clamping moving block 846 and the clamping seat 844. V-blocks 848 are hinged to both the upper and lower ends of the clamping moving block 846, and the middle part of the V-block 848 is hinged to the clamping moving block 846. Vertically extending clamping rollers 849 are hinged to the two ends of the two vertically opposite V-blocks 848. There are two of each set of moving shafts at a vertical interval. By adjusting the spring settings, clamping can accommodate errors in the outer roundness of the rubber sleeve. The use of V-blocks and two clamping rollers allows for clamping of rubber sleeves of different diameters. Protective covers are installed around each moving mechanism to safeguard it.

[0083] The working process of the automatic feeding device is as follows:

[0084] When the automatic trolley, carrying a rubber sleeve (usually in a rubber state without base adhesive, and in a blank state after base adhesive is applied), moves into the three-axis moving assembly and is fixed by the trolley fixing assembly, the three-axis moving assembly, carrying the material handling tensioner, moves into the corresponding rubber sleeve. Then, the material handling telescopic cylinder operates, causing the contact part to bulge the blank, thereby achieving material handling. Then, the three-axis moving assembly drives the rubber sleeve into the rubber sleeve positioning assembly. Then, the bidirectional moving assembly operates, causing the clamping roller to automatically center and clamp the rubber sleeve from the outside. Then, the material handling telescopic cylinder operates, causing the material handling tensioner to retract, and then the three-axis moving assembly drives the material handling tensioner to move out of the rubber sleeve located in the rubber sleeve positioning assembly.

[0085] Preferably, an automatic unloading device is also provided, which includes an unloading robot and an automatic trolley for placing finished products. The automatic trolley is an AGV trolley in the prior art. The unloading robot and the six-axis robot have the same structure and both include a forming unit. A tire blank transfer detection device for detecting the overall glue wrapping is also set between the unloading robot and the last six-axis robot. The tire blank transfer detection device needs to detect the absence of joints.

[0086] In the process of wrapping solid tires with rubber, the weight ratio of the grooved surface rubber, intermediate rubber, and base rubber is 5:3:2, with the tread rubber being the heaviest. To ensure overall efficiency, this embodiment uses four six-axis robots, which are used sequentially to wrap the base rubber, intermediate rubber, tread rubber, and tread rubber. Correspondingly, four pressing machines are also provided. In addition, to increase transfer efficiency, two tire blank transfer detection devices are set between the first type of intermediate rubber and the second type of tread rubber.

[0087] The overall work process is as follows:

[0088] 1) Material Picking and Clamping. The automatic trolley moves the tire blank into the three-axis moving assembly. Then, the three-axis moving assembly drives the material picking and shrinking device to pick up the material and move the tire blank to the rubber sleeve positioning assembly. The rubber sleeve positioning assembly achieves automatic centering and clamping. After the tire blank is clamped by the rubber sleeve positioning assembly, the material picking and shrinking device retracts and is then moved away from the rubber sleeve positioning assembly by the three-axis moving assembly, while the next tire blank is picked up.

[0089] 2) Base adhesive winding. The corresponding six-axis robot moves the forming device to the tire blank inside the rubber sleeve positioning assembly, then the forming bulge expands, tightening the tire blank from the inside. Then the bidirectional moving assembly works to loosen the tire blank, and the six-axis robot moves the forming device with the tire blank to the fixed length and width device to achieve base adhesive winding. After the base adhesive is wound, the six-axis robot places the tire blank with base adhesive on the tire blank transfer and detection device to detect the weight of the base adhesive winding and the joint.

[0090] 3) Complete the winding of the middle adhesive and the second tread, the winding principle of which is the same as that of the base adhesive. After completion, place the tire carcass with the winding number on the tire carcass transfer detection device in the automatic feeding device to check the weight and joints. When the weight is qualified and there are no joints, the feeding robot moves it to the automatic feeding trolley.
