Description

Technical Field

[0001] The present application relates to the technical field of vulcanization bladder production, and in particular to a tire vulcanization bladder pre-installation device and pre-installation method. Background Art

[0002] Tire curing bladder plays a vital role in the tire manufacturing process. As the inner mold of the tire mold, its main function is to form internal pressure by filling compressed air, nitrogen or superheated water during the vulcanization process, so that the tire rubber blank can be vulcanized quickly at high temperature. This method not only conducts heat quickly and efficiently, but also is easy to operate and reduces labor intensity. Due to the repeated expansion and contraction of the vulcanizing bladder and the high pressure and high temperature state, the vulcanizing bladder may crack after making 300-500 tire blanks, and needs to be replaced. The traditional way is to separate and install manually. In order to ensure the safety of the disassembly and assembly personnel, it is necessary to wait until the ambient temperature of the tire production site drops before the disassembly and assembly personnel replace the vulcanizing bladder, which prolongs the entire vulcanizing bladder replacement process and causes the ambient temperature of the tire production site to drop significantly. After the new vulcanizing bladder is replaced, more steam is needed to raise the temperature of the tire production site to the working temperature, resulting in energy waste.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-11 This application is described in further detail.

[0037] The inventor of the present application has found that in the process of replacing the old vulcanizing bladder 5 on the existing vulcanizing device, in order to ensure the safety of the disassembling and assembling personnel, it is necessary to wait until the ambient temperature of the tire manufacturing site is lowered before the disassembling and assembling personnel replace the vulcanizing bladder 5, which easily leads to the prolongation of the entire vulcanizing bladder 5 replacement process, causing the ambient temperature of the tire manufacturing site to drop significantly, and more steam is required to raise the temperature of the tire manufacturing site to the working temperature, resulting in energy waste. For this reason, the present application mainly adopts mechanical equipment to replace the manual replacement of the old vulcanizing bladder 5, so that the vulcanizing bladder 5 can be replaced without waiting for the ambient temperature of the site to drop, thereby shortening the entire vulcanizing bladder 5 replacement process, reducing the drop in the ambient temperature of the tire manufacturing site, and reducing the amount of steam required to raise the temperature of the tire manufacturing site to the working temperature, thereby achieving the effect of saving energy. The following is a further detailed description of the present application.

[0038] On the one hand, an embodiment of the present application discloses a tire curing bladder pre-assembly device.

[0039] Reference Figure 1 A tire curing bladder pre-installation device includes a movable frame assembly 1, a conversion assembly 2, and a disassembly assembly 3. The conversion assembly 2 is arranged on the movable frame assembly 1, and forms a new part station 41 for placing a new curing bladder 5 and an old part station 42 for placing an old curing bladder 5, and is used to swap the positions of the new part station 41 and the old part station 42. The disassembly assembly 3 is arranged on the movable frame assembly 1, and is used to disassemble the old curing bladder 5 from the curing device, place the old curing bladder 5 at the old part station 42, and install the new curing bladder 5 on the new part station 41 on the curing device.

[0040] When replacing the old vulcanization bladder 5, first place the new vulcanization bladder 5 at the new part station 41 of the conversion component 2, then the movable frame 11 component drives the conversion component 2 and the disassembly component 3 to move, and moves the disassembly component 3 to above the old vulcanization bladder 5 on the vulcanization device, the disassembly component 3 removes the old vulcanization bladder 5 and places it at the old part station 42 of the conversion component 2, the rotating component switches the position of the old part station 42 and the new part station 41, the disassembly component 3 moves the new vulcanization bladder 5 to the vulcanization device, and installs the new vulcanization bladder 5, and finally the movable frame 11 component evacuates the tire manufacturing site, and the replacement of the old vulcanization bladder 5 is completed.

[0041] Reference Figure 2 , Figure 3The vulcanization bladder 5 in this embodiment includes a bladder body 51 and two groups of flange plate groups 52 arranged in an upper and lower manner. The two groups of flange plate groups 52 are arranged at the openings at both ends of the bladder body 51. Each group of flange plate groups 52 includes two flange plates, one flange plate is located inside the bladder body 51, and the other flange plate is located outside the bladder body 51. The body wall of the bladder body 51 is located between the two flange plates. The two flange plates are connected by bolts, and the body wall of the bladder body 51 is clamped and fixed to form a connection structure at both ends of the bladder body 51. The vulcanization device is provided with a supply and discharge flow path seat 61 and a central movable column 62. The supply and discharge flow path seat 61 is cylindrical, and the central movable column 62 is slidably arranged in the supply and discharge flow path seat 61, and the upper and lower movements of its ends are realized by an external hydraulic cylinder. The inner hole diameter of the bottom flange plate group 52 is larger than the inner hole diameter of the top flange plate group 52, and the inner hole central movable column 62 of the top flange plate group 52 is slidably sealed. The flange plate group 52 at the bottom is sleeved on the supply and exhaust flow path seat 61 and is connected by threads. A support plate 63 and a fixing nut 64 are provided on the top of the central movable column 62. The support plate 63 is coaxially fixedly connected with the central movable column 62, and the diameter of the support plate 63 is smaller than the aperture of the inner hole of the bottom flange plate group 52, so that the support plate 63 can pass through the bottom flange plate group 52. The fixing nut 64 is threadedly sleeved on the central movable column 62. During installation, the top flange plate group 52 is located between the support plate 63 and the fixing nut 64. The fixing nut 64 presses and fixes the top flange plate group 52 on the support plate 63, thereby realizing the installation of the top flange plate group 52 and the central movable column 62.

[0042] Reference Figure 4 , Figure 5 In order to improve the stability of the shape of the vulcanizing bladder 5, two shaping grooves 53 are provided on the peripheral side walls of the top and bottom flange plate groups 52, and the two shaping grooves 53 are opposite to each other along the circumference of the flange plate group 52. The two flange plate groups 52 at the top and bottom are supported by a support rod 54, which is a U-shaped rod. One end of the support rod 54 is inserted into the shaping groove 53 of the top flange plate group 52, and the other end is inserted into the shaping groove 53 of the bottom flange plate group 52. The end of the support rod 54 is overfitted with the shaping groove 53, which improves the stability of the connection between the support rod 54 and the flange plate group 52. The shaping of the vulcanizing bladder 5 by the two support rods 54 is conducive to maintaining the stability of the shape of the vulcanizing bladder 5 and ensuring the centering of the two flange plate groups 52. Two slots 55 are provided on the peripheral side wall of one flange plate in the bottom flange plate group 52, and the two slots 55 are opposite to each other along the circumference of the flange plate.

[0043] Reference Figure 1The movable frame assembly 1 in this embodiment includes a frame 11 and an adjustment frame 12. The bottom of the frame 11 is rotatably provided with four wheels, and is equipped with a vehicle drive system to drive the four wheels to move. The frame 11 is also equipped with a vehicle supporting system such as a counterweight, a battery, an electric control box, and a steering rod, so that the operator can stand on the frame 11 to drive the chassis. The adjustment frame 12 is connected to the frame 11 through a space adjustment mechanism 13. The space adjustment mechanism 13 in this embodiment includes an X-axis moving frame 131 and a Z-axis moving frame 132. The X-axis moving frame 131 is slidably arranged on the frame 11, and is driven to slide along the X-axis direction by an electric cylinder structure arranged on the frame 11. The Z-axis moving frame 132 is slidably arranged on the X-axis moving frame 131, and is driven to slide along the Z-axis direction by an electric cylinder structure arranged on the X-axis moving frame 131. The adjustment frame 12 is slidably arranged on the Z-axis moving frame 132, and is driven to slide along the Y-axis direction by an electric cylinder arranged on the Z-axis moving frame 132.

[0044] Reference Figure 1 , Figure 4 A replacement station 141 and a standby station 142 are formed at the front and rear ends of the adjustment frame 12, respectively. The conversion assembly 2 in this embodiment includes a first placement plate 21, a second placement plate 22 and two connecting rods 23. The first placement plate 21 and the second placement plate 22 are arranged in parallel or in the same plane. Initially, the first placement plate 21 is located at the standby station 142 and is used as a new part station 41. The second placement plate 22 is located at the replacement station 141 and is used as an old part station 42. At this time, the first placement plate 21 and the second placement plate 22 are in the same plane. The new vulcanization bladder 5 is placed on the first placement plate 21, and the old vulcanization bladder 5 can be placed on the second placement plate 22. When the adjustment frame 12 is moved to the tire manufacturing site, during the replacement of the old vulcanization bladder 5, the high temperature at the tire manufacturing site preheats the new vulcanization bladder 5 on the first placement plate 21, thereby reducing the amount of steam used when the new vulcanization bladder 5 is heated to the working temperature, thereby achieving an energy-saving effect.

[0045] Reference Figure 4 , Figure 6 The two connecting rods 23 are respectively located on both sides of the first placement plate 21 and the second placement plate 22. Both ends of the two connecting rods 23 are fixed with rotating shafts 24. The rotating shafts 24 are vertically arranged with the connecting rods 23 and are rotatably inserted in the first placement plate 21 or the second placement plate 22 along the horizontal direction. The two rotating shafts 24 in the first placement plate 21 and the second placement plate 22 are arranged at intervals. A hinge shaft 25 is fixed at the middle position of the two connecting rods 23. The axes of the two hinge shafts 25 are coplanar. The two hinge shafts 25 are rotatably inserted on the adjusting frame 12. A first motor 26 is fixed on the adjusting frame 12. The first motor 26 corresponds to the hinge shaft 25 one by one. The output shaft of the first motor 26 is coaxially fixedly connected with the hinge shaft 25.

[0046] When the disassembly assembly 3 disassembles the old vulcanization bladder 5 and places it on the second placement plate 22 on the replacement station 141, the two first motors 26 synchronously drive the two connecting rods 23 to rotate. When the two connecting rods 23 rotate, the four hinge points formed with the first placement plate 21 and the second placement plate 22 are projected into the vertical plane to form a parallelogram structure, thereby ensuring that the first placement plate 21 and the second placement plate 22 are kept horizontal during use. When the connecting rod 23 rotates 180°, the first placement plate 21 rotates to the replacement station 141 together with the new vulcanization bladder 5, and the second placement plate 22 rotates to the standby station 142 together with the old vulcanization bladder 5, so that the positions of the new and old vulcanization bladders 5 are reversed, and there is no need to adjust the position of the new vulcanization bladder 5, thereby improving the accuracy of the position reversal of the new and old vulcanization bladders 5.

[0047] Reference Figure 4 , Figure 5 In order to improve the stability and position accuracy of the new vulcanization bladder 5 on the first placement plate 21, a positioning block 27 is fixed on the first placement plate 21. The positioning block 27 includes a positioning portion 271 and a guiding portion 272. The positioning portion 271 is cylindrical and matches the inner hole of the bottom flange plate group 52. When the vulcanization bladder 5 is placed on the first placement plate 21, the positioning portion 271 is plugged into the bottom flange plate group 52 to improve the position accuracy of the vulcanization bladder 5 on the first placement plate 21. The guiding portion 272 is located above the positioning portion 271 and is conical, which can guide the positioning portion 271 to be plugged into the inner hole of the bottom flange plate group 52, so that the positioning portion 271 is inserted into the bottom flange plate group 52. The first placement plate 21 is embedded with a first permanent magnet 273 to adsorb the bottom flange plate group 52, thereby improving the stability of the new vulcanization bladder 5 placed on the first placement plate 21.

[0048] Reference Figure 4 , Figure 5 A clamping and unloading member 28 is provided on the first placement plate 21. The clamping and unloading member 28 in this embodiment includes two linear cylinders 281. The two linear cylinders 281 are fixedly installed at the bottom of the first placement plate 21 and are arranged in opposite directions. A connecting rod 282 is fixedly provided on the piston rod of each linear cylinder 281.

[0055] When the flange plate group 52 at the bottom and the supply and exhaust flow path seat 61 are disassembled, the second cylinder 3111 drives the mounting ring 315 to descend to the old vulcanizing bladder 5, and makes the second rod 3162 descend to the height of the slot 55, and then the third motor 3131 drives the driving gear 3132 to rotate, and the driving gear 3132 drives the two first rods 3161 to approach each other, and the first rod 3161 drives the second rod 3162 to abut against the peripheral side wall of the flange plate group 52 at the bottom, and then the second motor 3122 drives the rotating gear 3121 to rotate, and the rotating gear 3121 drives the first rod 3161 to rotate, and the first rod 3161 drives the second rod body 3162 to rotate on the peripheral side wall of the bottom flange plate group 52.

[0056] Reference Figure 7 , Figure 8The nut disassembly and assembly part 32 in this embodiment includes a first linear mechanism 321, a nut sleeve 322, and a rotation drive mechanism 323. The first linear mechanism 321 in this embodiment is a first cylinder 3211, and in other embodiments it can also be a hydraulic cylinder, an electric cylinder or the like. The cylinder body of the first cylinder 3211 is fixedly arranged on the first mounting plate 3143 and is arranged downwardly. A base plate 3212 is fixedly arranged on the piston rod of the first cylinder 3211.

The third permanent magnet 3223 is used to adsorb the removed fixing nut 64 to ensure the stability of the fixing nut 64.

[0058] When the first cylinder 3211 and the second cylinder 3111 drive the nut sleeve 322 and the disassembly rod 316 to change their positions, the distance sensor is used to control the moving distance of the nut sleeve 322 and the disassembly rod 316. The motors used above all have a self-locking function to improve the stability of the replacement process.

[0059] Reference Figure 4 A machine vision function module 7 is provided on the adjustment frame 12, and the machine vision function module 7 includes a visual camera 71. The visual camera 71 controls the servo motor in the electric cylinder in the space adjustment mechanism 13 and the fourth motor 3233 to position the nut sleeve 322 and the fixing nut 64.

[0060] The first is center positioning: First, the camera needs to be calibrated to obtain the camera's intrinsic parameters (focal length, principal point coordinates, etc.) and extrinsic parameters (position vector and rotation matrix, etc.), which are used to convert the image coordinate system into a three-dimensional space coordinate system; detect feature points (such as corner points, edges, etc.) in the image, and find the corresponding points of these feature points in different images or models through matching algorithms; use the feature point matching results, combined with the camera's intrinsic and extrinsic parameters, and solve the camera's attitude (rotation and translation vectors) relative to the world coordinate system through geometric principles (such as the PnP problem, i.e., the Perspective-n-Point problem); in plane positioning, some markers with known positions (such as ArUco markers) are usually placed on the plane, and the camera determines its position on the plane by detecting these markers. Through the 2D image coordinates of the detected markers and their 3D coordinates in the world coordinate system, combined with the camera's intrinsic parameters, the camera's attitude (rotation vector and translation vector) can be solved using functions such as cv2.solvePnP(); for targets on the plane, the coordinates of the target can be determined by calculating the intersection of the ray from the camera to the target point and the known plane (such as the ground). This usually involves converting the target point in the camera coordinate system to the world coordinate system and calculating the intersection with the plane; once the position of the camera and the target in the world coordinate system is determined, this information can be used to control the corresponding servo motor to drive the mobile frame to move to the specified position. This usually involves path planning and obstacle avoidance algorithms to ensure that the mobile structure can reach the target position safely and efficiently; during the movement of the mobile structure, the visual camera 71 can continuously provide feedback and adjust the moving path by comparing the actual position and the target position to ensure that it reaches the destination accurately.

[0061] The second is the morphological positioning of the nut sleeve 322 and the fixed nut 64: first, the template posture image of the nut is obtained through calibration, and the nut is identified using an algorithm based on the improved Faster-RCNN. The rotation angle of the nut and the ratio relative to the template nut image are solved by an algorithm based on Fourier and logarithmic polar coordinate transformation, and then the rotation angle of the sleeve is obtained. The motion control law is established using the visual feedback error, which is converted into a Cartesian space error through the image Jacobian matrix. The fourth motor 3233 is controlled by a PI controller to drive the nut sleeve 322 to rotate, and the rotational freedom of the sleeve is adjusted to achieve posture alignment. Then the first cylinder 3211 drives the nut sleeve 322 to descend, so that the nut sleeve 322 is sleeved on the fixed nut 64.

[0062] The implementation principle of a tire curing bladder pre-installation device according to an embodiment of the present application is as follows: two support rods 54 are respectively inserted into the shaping grooves 53 of a new curing bladder 5 to shape the new curing bladder 5, and then the new curing bladder 5 is placed on the first placement plate 21, and the positioning portion 271 is inserted into the inner hole of the flange plate group 52 at the bottom, and the new curing bladder 5 is rotated so that the two support rods 54 are aligned with the two second permanent magnets 283.

At this time, the fixed nut 64 is inserted into the hexagonal sleeve hole 3221, and the center movable column 62 is inserted into the center hole 3222.
