[0024] Step one, first time code scanning of the tire: the tire enters the conveying belt on the code scanning workbench, the tire moves along with the conveying belt, the code scanning device installed on the code scanning support frame scans the tire to obtain the bar code number of the tire, and downloads the parameters of the tire from the customer system, the scanning result is recorded as a1, and the result is transmitted to the computer control system connected with the tire code scanning device; the computer control system starts the equipment in each process step according to the parameter a1;

The rolling static friction between the spike wheel 512 and the sponge strip provides driving force for the movement of the sponge strip, preventing the sponge strip from being blocked in the L-shaped track 501.

A pair of nuts 516 with opposite moving directions are threadedly sleeved on the screw rod 514, and a first limiting piece 517 is fixedly connected to each nut 516. Another first limiting piece 517 is fixedly connected to another pair of nuts 516 with the same moving direction. When the screw rod 514 is rotated, the nuts 516 move towards or away from each other along the screw rod 514, and the first limiting piece 517 moves with the nut 516. Since the sponge strip moves between the pair of first limiting pieces 517, adjusting the distance between the pair of first limiting pieces 517 can adjust the width of the sponge strip.

[0104] The gear adjusting type width adjusting mechanism is located at the curved part of the C track 502, as shown in Figure 9 The specific structure is shown in Figure 13 , Figure 16 and Figure 17 .

[0106] As shown in Figure 18 The first tire code scanning assembly 6 and the second tire code scanning assembly 12 are the same in structure, and both comprise a code scanning workbench and a code scanning device 601. The lower end surface of the code scanning workbench is fixedly connected with a support leg 602. The code scanning workbench is provided with a conveying belt 603, a pair of protective fences 604 and a pair of guide doors 605. The conveying belt 603 is driven by a first electric roller 606, and the first electric roller 606 is driven by a first driving motor. In order to clearly show the connection mode of the conveying belt 603 and the first electric roller 606, the first driving motor is not shown in the figure. The pair of protective fences 604 are symmetrically distributed on the two sides of the conveying belt 603, and the protective fences 604 are provided with a plurality of freely rotating rollers 607. The pair of guide doors 605 are symmetrically distributed on the two sides of the conveying belt 603, and the pair of guide doors 605 are rotatably connected to the code scanning workbench. The guide doors 605 are provided with a plurality of freely rotating rollers 607. The code scanning workbench 601 is provided with a code scanning support frame 608 above, and the code scanning support frame 608 is fixedly installed with the code scanning device 601.

[0107] When the tire contacts the pair of guide doors 605, the tire and the pair of guide doors 605 are extruded with each other. Since the guide doors 605 are symmetrically arranged, when the tire deviates from the center line of the conveying belt 603, the extrusion forces between the two guide doors 605 and the tire are different, and the extrusion force between the deviated guide door 605 and the tire is larger. Therefore, the tire is forced to move towards the center line of the conveying belt 603, so that the tire moves towards the center line of the conveying belt 603 during the extrusion process of the guide door 605, and finally the tire returns to the center line position of the conveying belt 603, so as to ensure that the tire enters the first weighing assembly 8 at the middle position of the first weighing assembly 8, which is beneficial to improve the accuracy of weighing.

[0108] AsFigures 19-20 As shown, the first weighing assembly 8 and the second weighing assembly 13 are structurally identical, and each includes a first weighing support frame 801 and a second weighing support frame 802, the second weighing support frame 802 being arranged above the first weighing support frame 801; the first weighing support frame 801 is fixedly connected with an electronic scale 803, and the scale surface of the electronic scale 803 is fixedly connected with a plurality of first tire supporting rods 804;

[0109] The second weighing support frame 802 is connected with the lifting workbench 805 through a height adjusting assembly, and the lifting workbench 805 is provided with a plurality of first rolling support devices 806 which are freely rotatable about their own axes; the first tire supporting rods 804 and the first rolling support devices 806 are distributed alternately; the first rolling support device 806 is composed of an electric roller and a disc which is concentrically fixed on the electric roller; the second weighing support frame 802 and the first weighing support frame 801 are connected through the height adjusting assembly; the height adjusting assembly includes a first air cylinder 807, the first air cylinder 807 being fixedly connected to the second weighing support frame 802, the first air cylinder 807 being rotatably connected with a first lifting connecting rod 808, the two ends of the first lifting connecting rod 808 being rotatably connected with a first connecting plate 813 respectively, each first connecting plate 813 being fixedly connected with a second lifting connecting rod 809, the two ends of the second lifting connecting rod 809 being rotatably connected to a first connecting seat 814 respectively, a pair of second lifting connecting rods 809 being fixedly connected with a second connecting plate 810, the second connecting plate 810 being rotatably connected with a third lifting connecting rod 811, and the third lifting connecting rod 811 being fixedly connected with the lifting workbench 805 through a second connecting seat 812.

[0110] The first air cylinder 807 is lifted to push the first lifting connecting rod 808 to elongate so as to lower the first rolling support device 806 to support the tire completely on the first tire supporting rod 804. At this time, the first rolling support device 806 is completely separated from the tire.

[0111] After the electronic scale 803 reads the tire weight value, the first air cylinder 807 is retracted to pull the first rolling support device 806 to rise to completely hold the tire, at which time the first tire supporting rod 804 is completely separated from the tire.

[0112] When the tire enters the first weighing assembly 8, it is first supported by the first rolling support device 806, and then the height adjusting assembly lowers the height of the lifting workbench 805, when the height of the first rolling support device 806 is lower than that of the first tire supporting rod 804, the tire is supported by the first tire supporting rod 804, at which time the electronic scale 803 reads the weight of the tire.

[0113] As Figures 21-27As shown, the gluing assembly 9 includes a multifunctional workbench, a gluing robot 901, a plurality of glue barrels 902, and a glue supply pump 903. In the embodiment, a single glue barrel 902 can be provided, or a plurality of glue barrels 902 can be provided.

[0114] The multifunctional workbench includes a fixed support frame 16 and a movable workbench 17. The movable workbench 17 is supported by the fixed support frame 16. The fixed support frame 16 is provided with a plurality of second electric rollers 18 fixedly connected thereto. A plurality of circular support plates 19 are coaxially fixed to the second electric rollers 18. The movable workbench 17 is fixedly connected with a plurality of second tire supporting rods 20 of fixed height. The second tire supporting rods 20 are uniformly distributed around the tire axis. A plurality of shaft sleeves 30 are rotatably sleeved on the second tire supporting rods 20. The tire is in contact with the shaft sleeve 30, which can reduce the resistance when the tire rotates. The shaft sleeve 30 is rotatably sleeved on the region of the second tire supporting rod 20 in contact with the tire. The shaft sleeve 30 is in direct contact with the tire. By providing the shaft sleeve 30, the resistance of the tire when rotating is smaller.

[0115] The multifunctional workbench further includes a centering and synchronous clamping mechanism. The centering and synchronous clamping mechanism includes a pair of electric roller support driving centering devices 21 symmetrically distributed about the movable workbench 17. A pair of coating rollers 22 are rotatably connected to each electric roller support driving centering device 21. An encoder 23 and a third driving motor 24 are installed on each electric roller support driving centering device 21. The output shaft of the third driving motor 24 is fixedly connected to the rotating shaft of the coating roller 22. In the embodiment, a pair of encoders 23 and a pair of third driving motors 24 are provided in the centering and synchronous clamping mechanism. In the following, one electric roller support driving centering device 21 will be taken as an example to introduce the connection mode of the encoder 23, the third driving motor 24, and the electric roller support driving centering device 21. One third driving motor 24 is fixedly installed on each electric roller support driving centering device 21. The output shaft of the third driving motor 24 is fixedly connected to the rotating shaft of one coating roller 22, which is a driving roller providing driving force for the rotation of the tire. The encoder 23 is connected to the other coating roller 22, which rolls under the driving of the rotating tire. The encoder 23 monitors the rotation speed and angle of the tire by monitoring the motion parameters of the tire.

[0116] A pair of pulleys 25 are symmetrically arranged on the fixed support frame 16, and the pulleys 25 are connected by a second belt 26. A pair of fourth sliding rails 27 are fixedly connected to the fixed support frame 16. The electric roller support driving centering device 21 is slidably connected to the fourth sliding rails 27 through a third sliding block 28. The pair of electric roller support driving centering devices 21 are fixedly connected to the second belt 26, and the connection positions of the pair of electric roller support driving centering devices 21 to the second belt 26 are symmetric about the center of the second belt 26. The second belt 26 is fixedly connected to a second air cylinder 29. The movable end of the second air cylinder 29 is telescopically movable. Under the driving of the second air cylinder 29, the second belt 26 rotates, and the pair of electric roller support driving centering devices 21 move towards or away from each other. When the pair of electric roller support driving centering devices 21 move towards each other, the two pairs of rubber coating rollers 22 move towards the tire and finally clamp the tire. When the pair of electric roller support driving centering devices 21 move away from each other, the two pairs of rubber coating rollers 22 move away from the tire, facilitating the tire to leave or enter the multifunctional operation table.

[0117] The glue supply pump 903 is connected to one glue barrel 902, and the glue supply pump 903 is connected to the glue applying robot 901.

[0118] In use, the workbench 17 is in the lifting position. The tire first enters the movable workbench 17 through a plurality of second electric rollers 18 rotating about their own axes. Then the movable workbench 17 drives the second electric rollers 18 to descend. A plurality of fixed second tire supporting rods 20 support the tire to the clamping area of the two pairs of rubber coating rollers 22. The outer side of the tire is in contact with the two pairs of rubber coating rollers 22. The rubber coating rollers 22 rotate, and the tire rotates under the action of static friction. The glue outlet of the glue applying robot 901 penetrates into the interior of the tire and is positioned at the position to be coated with glue. Glue is applied to each area on the inner wall of the tire by the rotation of the tire. When there is one glue barrel 902, the interior of the glue barrel 902 contains one type of glue solution. The glue supply pump 903 extracts the glue solution from the interior of the glue barrel 902. When the extraction of the glue solution from the interior of the glue barrel 902 is completed, the interior of the glue barrel 902 is filled with glue solution again.

[0119] The interiors of a plurality of glue barrels 902 can contain the same type of glue solution or different types of glue solution. When the interiors of the plurality of glue barrels 902 contain the same type of glue solution, the glue supply pump 903 extracts the glue solution from the interior of one glue barrel 902. When the extraction of the glue solution from the interior of the glue barrel 902 is completed, the glue solution is extracted from the interior of another glue barrel 902. When the interiors of the plurality of glue barrels 902 contain different types of glue solution, the glue supply pump 903 simultaneously extracts the glue solution from the interiors of two glue barrels 902. The encoder 23 records the number of rotations and the rotation rate of the rubber coating rollers 22. Since the number of rotations and the rotation rate of the rubber coating rollers 22 can represent the number of rotations and the rotation rate of the tire, and the number of rotations and the rotation rate of the rubber coating rollers 22 are related to the amount of glue applied and the uniformity of glue application, real-time monitoring of the amount of glue applied and the uniformity of glue application can be realized by real-time monitoring of the tire through the encoder 23.

[0120] The glued tire enters the sponge assembly 10, the sponge assembly 10 includes a multifunctional workbench, the sponge strip first passes through a plurality of second electric rollers 18 to enter the movable workbench 17, then the movable workbench 17 is lifted with the plurality of second electric rollers 18, the plurality of second electric rollers 18 lift the tire to the clamping area of the coating roller 22, the outer side of the tire is in contact with two pairs of coating rollers 22, the coating roller 22 rotates, and the tire rotates under the action of static friction; at the same time, the sponge strip enters the tire interior through the C rail 502 and is attached to the interior of the tire;

[0121] Then the tire enters the pressing assembly 11, the pressing assembly 11 tightly presses the sponge strip on the tire. The specific structure of the pressing assembly 11 has been disclosed in the patent No. 2022105693241, which will not be described in detail here; the relative moving screw strutting mechanism is used to straddle the tire sub-port, and the sponge is transmitted to the pressure wheel at the outlet of the C rail 502, and the sponge is preliminarily attached to the inner wall of the tire; the relative moving screw strutting mechanism is used to straddle the tire sub-port, and cooperates with a set of pressing roller mechanism to roll and press the preliminarily attached sponge; the sponge pressing assembly 11 is provided with a tire straddling mechanism and a pressing roller mechanism; wherein the tire straddling mechanism has been disclosed in the patent No. 2022202961412.

[0122] The tire out of the pressing assembly 11 enters the second tire code scanning assembly 12, which has the same working principle as the first tire code scanning assembly 6, and then enters the second weighing assembly 13, which has the same weighing principle as the first weighing assembly 8.

[0123] The mute cotton attachment quality detection and discrimination assembly 14 uses a 3D laser sensor or a laser distance sensor as a corresponding data detection device for the sponge attachment in the tire interior, and compares the data with the computer system to determine the quality of the tire.

[0125] The sponge lifting device 2, the positioning flap conveying mechanism 3, the sponge cutting device 4 and the sponge conveying mechanism 5 are arranged, so that automatic feeding, transportation, cutting and transmission of the sponge strip to the sponge pasting station can be realized; the width of the sponge drawer 102 is adjustable, and the width of the mute sponge pasted in the tire can be adjusted by matching the width adjustment function of the C rail 502; in the embodiment, the sponge cutting device is arranged and is automatically controlled by the computer control system, so that the whole sponge strip close to the inner diameter length of the tire can be divided into multiple sections according to the customer's demand and pasted on the inner wall of the tire according to the customer's demand, and the multiple-section pasted sponge strip is formed; in the embodiment, the width of the sponge positioning and clamping fence 108 is adjusted, and the second sliding block 109 is slidably connected with the second sliding rail 107 and fixed by a bolt, so that the width between the pair of sponge positioning and clamping fences 108 can be freely adjusted, so that the width of each sponge drawer 102 can be adjusted to adapt to the transportation of sponge strips with different widths; the first tire code scanning assembly 6 is arranged, so that the size and other parameters of each tire entering the assembly line can be obtained, the parameters of each tire on the production line and the information of each step in the production process of the tire can be monitored, and the second tire code scanning assembly 12 is combined, so that the parameters of each tire flowing out of the production line can be monitored; the first weighing assembly 8 is arranged, so that the net weight of the tire entering the assembly line can be monitored, and the second tire code scanning assembly 12 is arranged, so that the weight of the tire after the glue coating and sponge pasting operation can be monitored; if the weight difference before and after is within the set range value and the code scanning information before and after is consistent, it is indicated that the glue coating amount and the sponge strip pasting are normal, otherwise, if the weight difference and the code scanning information do not match, it is indicated that the tire with the sponge strip may be a defective product, and manual intervention is required for judgment. Automatic monitoring in the production process is realized; 3D detection or laser detection is used to detect the quality of the internal sponge pasting; the continuous multi-section mute sponge tire production equipment and the production method thereof can form a complete automatic production device, the area occupied is small, the tire can be monitored in real time, and the automatic work of pasting the sponge strip in the tire is realized, so that the device is convenient to use and high in production efficiency.

[0126] In the embodiment, cameras are arranged on the C rail, the L rail 501, the glue coating robot 901 and the sponge lifting device 2; the technician can observe whether the sponge is blocked in the conveying process in real time through the cameras on the C rail and the L rail 501, and the technician can adjust in real time if the sponge is blocked; the technician can observe the width of the sponge, the working condition of the grabbing and placing process in real time through the camera on the sponge lifting device 2; the technician can observe the glue coating condition of the inner wall of the tire in real time through the camera on the glue coating arm, for example, whether the glue solution is completely coated on the inner wall of the tire, whether the glue solution coating thickness is uniform and the like;

[0127] By setting up cameras on the C track, the L track 501, the gluing robot 901 and the sponge lifting device 2, in addition to being able to realize real-time monitoring of production status and adjusting production process in the first time, it is also convenient to trace the technical reasons. For example, when defective products appear, the video of the production status can be traced to assist the technician in judging the technical reasons.

[0128] The device provided by the application can paste a single sponge strip or multiple sponge strips inside the tire, while the device provided by the prior art can only paste a single sponge strip.

[0129] The opening mechanism in the application can open the tire, which can increase the width of the sponge strip pasted on the inner wall of the tire. The technical effect of increasing the width of the sponge strip is to increase the coverage area of the sponge strip on the inner wall of the tire. The larger the coverage area of the sponge strip, the stronger the tire quieting effect.

[0130] The width of the sponge drawer 102 in the application can be adjusted, and the C track 502 and the width adjusting device provided on the C track 502 can be used together to realize the conveying of sponge strips of different widths on the production line. Since the width of the sponge strip is one-to-one corresponding to the size of the tire, the production equipment provided by the application can paste a sponge strip inside a tire of different sizes, that is, the production equipment provided by the application can be applied to the production of pasting a sponge strip on a tire of multiple sizes, and the application range is wider.

[0131] In the application, the pressing of the sponge strip is realized by the relative rolling between the rolling device and the sponge strip. When rolling and pressing, the rolling friction force exists between the sponge strip and the rolling device, which is smaller than the sliding friction force, and will not take away the sponge, so the sponge strip will not wrinkle. Moreover, the rolling device in the application itself has the same linear speed as the inner wall of the tire under the driving of the driving device, so the rolling device will not take away the sponge strip, ensuring that the sponge strip can be more comfortably pasted on the inner wall of the tire.

[0132] Example 2

[0133] The embodiment provides a continuous multi-section quieting sponge tire production method, and the production method comprises the following steps:

[0134] Step one, the first time the tire code scanning: tire into the code scanning workbench on the conveyor belt 603, tire with the conveyor belt 603 moves, the CCD code scanning device 601 installed on the code scanning support frame 608 on the tire code scanning, get the tire bar code number, and download the parameters of this tire from the customer system, code scanning results recorded as a1 and the results are sent to the computer control system connected with the tire scanning device 601; the computer control system according to the parameter a1 start each process step in the device, including sponge lifting device, positioning flap conveying mechanism, sponge cutting device, sponge transmission mechanism, tire inner wall laser cleaner 7, the first weighing assembly 8, glue assembly 9, paste sponge assembly 10, pressure assembly 11, the second tire code scanning assembly 12, the second weighing assembly 13, the quality detection and discrimination assembly 14 and laser marking machine 15, and use the a1 parameters obtained to complete the subsequent tire inner wall cleaning work.

[0135] Step two, the a1 parameters obtained are input into the tire inner wall laser cleaner 7, and the tire inner wall laser cleaner 7 starts the cleaning formula, clamping parameters, cleaning width and cleaning rate according to the parameters a1;

[0136] The tire inner wall laser cleaner 7 selects the corresponding cleaning liquid; the clamping device built in the tire inner wall laser cleaner 7 selects the corresponding rotation rate, and the laser cleaning part of the tire inner wall laser cleaner 7 adopts the corresponding cleaning rate for cleaning; after cleaning, the tire is conveyed to the weighing operation area;

[0137] Step three, the first time the tire is weighed: the laser cleaned tire is conveyed to the weighing operation area, and the tire is weighed for the first time at this time, the net weight w1 of the tire is obtained, and the information of w1 is conveyed to the computer control system;

[0138] The laser cleaned tire first passes through the first rolling support device 806, and the lifting workbench 805 drives the first rolling support device 806 to descend together until the tire is supported by the first tire supporting rod 804, at which time the electronic scale 803 weighs the tire for the first time; the net weight w1 of the tire is obtained; the information of the result w1 is transmitted to the computer control system;

[0139] Step four, tire glue coating: the tire enters the glue assembly 9 according to the calculated amount of glue coating on the inner side of the tire, and the computer is connected with the glue pump and provides the amount of glue supply for the glue pump; the glue pump coats the glue on the tire according to the amount calculated by the computer;

[0140] Step five, the sponge is transported to the sponge lifting device working area by the sponge moving cart 1 to wait for loading; when the sponge strips inside the sponge drawer 102 are all used up, the empty sponge drawer 102 in the sponge lifting device 2 is removed and replaced with the full sponge drawer 102 on the sponge cart; the sponge lifting device 2 takes out the sponge strips from the inside of the sponge drawer 102 and puts them into the turnover mechanism, the sponge strips enter the L track 501 from the turnover mechanism, and the sponge cutting device 4 cuts the sponge according to the required length; the sponge cutting device 4 can cut the sponge strip according to the required length standard, or cut it according to a length less than the required length, when the sponge strip is cut according to a length less than the required length, that is, a sponge strip is composed of several sponge strips;

[0141] Then the L track 501 rises to the same height as the C track 502, and the sponge strip is transferred from the L track 501 to the inside of the C track 502; finally, it is sent into the sponge applying assembly 10 through the C track 502 and applied to the inside of the tire coated with glue; after the sponge is applied inside the tire, it will also be subjected to a pressure holding operation, that is, the sponge is tightly pressed inside the tire by the pressure roller device;

[0142] The pressure holding operation means that the pressure roller device contacts the sponge strip in a rolling manner and exerts a certain pressure on the surface of the sponge strip, so as to realize the complete adhesion of the sponge strip to the inside of the tire; for example, there may be air bubbles between the sponge strip and the inner wall of the tire or the sponge strip may have wrinkles, which will cause the sponge strip to not adhere firmly to the inner wall of the tire, and finally affect the performance of the product;

[0143] In this embodiment, the specific implementation of the pressure holding operation is as follows:

[0144] The rolling pressure device is provided with a driving device, and the rolling pressure device rotates around its own axis under the driving of the driving device. When the linear speed of the outer wall of the rolling pressure device is the same as the linear speed of the inner wall of the tire, there is no friction between the rolling pressure device and the sponge strip, so the rolling pressure device will not take away the sponge strip. The surface of the sponge strip will not wrinkle, the sponge strip will be more stretched on the surface of the tire, and the adhesion to the tire will be more tight, and the adhesion effect will be better.

[0145] In this embodiment, the rolling pressure device can adopt a rolling cylinder type or a multi-piece type; the multi-piece type rolling pressure device has a better adhesion effect at the lead angle area of the tire.
