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-assembly device and pre-assembly method. Background Art

[0002] Tire curing bladders play a crucial role in the tire manufacturing process. Serving as the inner mold of the tire mold, their primary function is to create internal pressure during the curing process by inflating the tire with compressed air, nitrogen, or superheated water, thereby rapidly curing the tire rubber at high temperatures. This method not only conducts heat quickly and efficiently, but also is easy to operate and reduces labor intensity.

[0003] Due to the repeated expansion and contraction of the vulcanizing bladder and the high pressure and high temperature conditions, the vulcanizing bladder may crack after making 300-500 tire blanks. At this time, it needs to be replaced. The traditional method is to manually separate and install it. To ensure the safety of the disassembly and assembly personnel, it is necessary to wait until the ambient temperature at the tire production site drops before the disassembly and assembly personnel can replace the vulcanizing bladder, which prolongs the entire vulcanizing bladder replacement process and causes the ambient temperature at the tire production site to drop significantly. After the new vulcanizing bladder is replaced, more steam is needed to raise the temperature at the tire production site to the operating temperature, resulting in energy waste. Summary of the Invention

The direct insertion mechanism can drive the disassembly rod to insert into the slot, so that the rotating mechanism can drive the flange plate group at the bottom to rotate.

[0016] By adopting the above technical solution, when disassembling the bottom flange plate assembly, the second linear mechanism drives the disassembly rod to move downward to the side of the bottom flange plate assembly, and then the straight insertion mechanism drives the disassembly rod to be inserted into the slot. Then, the rotation mechanism drives the disassembly rod to rotate, thereby driving the bottom flange plate assembly to rotate and remove the vulcanization bladder from the vulcanizing device. Then, the second linear mechanism drives the disassembly rod to lift, and the disassembly rod can be inserted into the slot to remove the old vulcanization bladder from the vulcanizing device, thereby improving the automated disassembly of the old vulcanization bladder.

[0017] When installing a new vulcanization bladder, the straight-insertion mechanism drives the disassembly rod to be inserted into the slot, and then the second linear mechanism drives the new vulcanization bladder to move down to the supply and discharge flow path seat, and then the rotating mechanism drives the disassembly rod to rotate, thereby driving the bottom flange plate group to be screwed onto the supply and discharge flow path seat, and then the nut sleeve is used to screw the fixing nut to complete the installation of the new vulcanization bladder.

When the second rod slides to be opposite to the slot, the telescopic spring pushes the second rod to be inserted into the slot, thereby improving the convenience of the disassembly rod and the slot.

[0020] Preferably, the movable frame assembly includes a vehicle frame and an adjustment frame, the conversion assembly and the disassembly assembly are both arranged on the adjustment frame, the adjustment frame and the vehicle frame are connected through a space adjustment mechanism to be able to adjust the position of the nut sleeve, and the machine vision function module and the space adjustment mechanism are used to enable the nut sleeve to be aligned with the fixing nut.

During the rotation process, the first placement plate and the second placement plate always remain horizontal with the ground to ensure the stability of the placement of the new and old vulcanization bladders. Then the first placement plate and the second placement plate exchange positions. During this process, since the rotation centers of the two connecting rods are located at their own center positions, there is no need to re-position the new vulcanization bladder, thereby improving the accuracy of the exchange positioning of the new and old vulcanization bladders and the positioning accuracy.

[0024] Preferably, forming grooves are provided on the circumferential side walls of the two groups of flange plate groups, and the vulcanizing bladder is provided with support rods inserted into the two forming grooves, and the support rods are used to support the two flange plate groups.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. Mechanical devices replace manual curing bladders, eliminating the need to wait for the ambient temperature on site to drop before replacing the bladders. This shortens the entire bladder replacement process and reduces the drop in ambient temperature at the tire manufacturing site. Furthermore, when replacing an old bladder, the new one is preheated by the high temperature on site, reducing the amount of steam required to raise the temperature at the tire manufacturing site to operating temperature and thus saving energy.

[0038] 2. By driving the two hinged shafts to rotate synchronously, the first and second placement plates always remain level with the ground during the rotation process, ensuring the stability of the placement of the new and old curing bladders. The first and second placement plates are then swapped. During this process, since the rotation centers of the two connecting rods are at their own center positions, there is no need to reposition the new curing bladder, improving the accuracy of the exchange and positioning of the new and old curing bladders.

[0039] 3. The support rod is inserted into the forming groove on the two sets of flange plates to ensure the stability of the position of the two sets of flange plates, which is convenient for positioning the vulcanization bladder. When the disassembly rod is inserted into the slot on the flange plate at the bottom of the new vulcanization bladder, the clamping unloading piece clamps the support rod and pulls the support rod out of the forming groove, effectively avoiding the influence of the support rod on the expansion of the vulcanization bladder.

DETAILED DESCRIPTION

[0052] The following is combined with Figure 1-11 This application is described in further detail.

[0053] The inventors of this application have discovered that, during the replacement process of the old vulcanization bladder 5 on the existing vulcanization device, in order to ensure the safety of the disassembly and assembly personnel, the disassembly and assembly personnel must wait until the ambient temperature at the tire production site drops before replacing the vulcanization bladder 5. This can easily prolong the entire vulcanization bladder 5 replacement process, causing the ambient temperature at the tire production site to drop significantly, requiring more steam to be consumed to raise the temperature at the tire production site to the operating temperature, resulting in energy waste. To this end, this application primarily uses mechanical equipment to replace the old vulcanization bladder 5. This eliminates the need to wait until the ambient temperature at the site drops before replacing the vulcanization bladder 5, thereby shortening the entire vulcanization bladder 5 replacement process, reducing the drop in the ambient temperature at the tire production site, and reducing the amount of steam required to raise the temperature at the tire production site to the operating temperature, thereby achieving energy conservation. The following further describes this application in detail.

[0054] In one aspect, embodiments of the present application disclose a tire curing bladder pre-assembly device.

[0055] 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 in the old part station 42, and install the new curing bladder 5 on the new part station 41 on the curing device.

[0056] When replacing the old vulcanization bladder 5, first place the new vulcanization bladder 5 at the new part station 41 of the conversion assembly 2, then the movable frame 11 assembly drives the conversion assembly 2 and the disassembly assembly 3 to move, and moves the disassembly assembly 3 to above the old vulcanization bladder 5 on the vulcanization device, the disassembly assembly 3 removes the old vulcanization bladder 5 and places it at the old part station 42 of the conversion assembly 2, the rotating assembly swaps the positions of the old part station 42 and the new part station 41, the disassembly assembly 3 moves the new vulcanization bladder 5 to the vulcanization device, and installs the new vulcanization bladder 5, finally the movable frame 11 assembly evacuates the tire manufacturing site, and the replacement of the old vulcanization bladder 5 is completed.

[0057] Reference Figure 2 、 Figure 3The curing bladder 5 in this embodiment includes a bladder body 51 and two upper and lower flange plate assemblies 52. The two flange plate assemblies 52 are located at the two end openings of the bladder body 51. Each flange plate assembly 52 includes two flange plates, one located inside the bladder body 51 and the other 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 clamped to secure the body wall of the bladder body 51, forming a connection structure at both ends of the bladder body 51. The curing device is equipped with a supply and discharge flow channel seat 61 and a central movable column 62. The supply and discharge flow channel seat 61 is cylindrical, and the central movable column 62 slides through the supply and discharge flow channel seat 61. The upper end of the central movable column 62 is moved up and down by an external hydraulic cylinder. The inner diameter of the bottom flange plate assembly 52 is larger than that of the top flange plate assembly 52. The inner bore of the top flange plate assembly 52 is provided with a sliding and sealing engagement with the central movable column 62. The bottom flange plate group 52 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 to 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 the top flange plate group 52 against the support plate 63 to realize the installation of the top flange plate group 52 and the central movable column 62.

[0058] Reference Figure 4 、 Figure 5 To improve the stability of the curing bladder 5, two shaping grooves 53 are defined on the circumferential sidewalls of each of the top and bottom flange plate assemblies 52. These grooves 53 are circumferentially opposed to each other. The top and bottom flange plate assemblies 52 are supported by a U-shaped support rod 54, one end of which is inserted into the shaping groove 53 of the top flange plate assemblies 52 and the other end into the shaping groove 53 of the bottom flange plate assemblies 52. The ends of the support rod 54 are overfitted into the shaping groove 53, improving the stability of the connection between the support rod 54 and the flange plate assemblies 52. The two support rods 54 shape the curing bladder 5, maintaining its shape and ensuring the centering of the two flange plate assemblies 52. Two slots 55 are defined on the circumferential sidewall of one flange plate in the bottom flange plate assemblies 52, circumferentially opposed to each other.

[0059] Reference Figure 1The movable frame assembly 1 in this embodiment includes a vehicle frame 11 and an adjustment frame 12. The bottom of the vehicle frame 11 is rotatably provided with four wheels and is equipped with a vehicle drive system to drive the four wheels to move. The vehicle frame 11 is also equipped with a vehicle supporting system such as a counterweight, a battery, an electric control box, and a steering column, so that the operator can stand on the vehicle frame 11 to drive the vehicle chassis. The adjustment frame 12 is connected to the vehicle frame 11 through a space adjustment mechanism 13. The space adjustment mechanism 13 in this embodiment includes an X-axis movable frame 131 and a Z-axis movable frame 132. The X-axis movable frame 131 is slidably set on the vehicle frame 11 and is driven to slide along the X-axis direction by an electric cylinder structure set on the vehicle frame 11. The Z-axis movable frame 132 is slidably set on the X-axis movable frame 131 and is driven to slide along the Z-axis direction by an electric cylinder structure set on the X-axis movable frame 131. The adjustment frame 12 is slidably set on the Z-axis movable frame 132 and is driven to slide along the Y-axis direction by an electric cylinder set on the Z-axis movable frame 132.

[0060] 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 parallel or coplanar. Initially, the first placement plate 21 is located at the standby station 142 and serves as the new part station 41, and the second placement plate 22 is located at the replacement station 141 and serves as the old part station 42. At this time, the first placement plate 21 and the second placement plate 22 are coplanar, and the new curing bladder 5 is placed on the first placement plate 21, and the old curing bladder 5 can be placed on the second placement plate 22. When the adjustment frame 12 is moved to the tire manufacturing site, the high temperature at the tire manufacturing site preheats the new curing bladder 5 on the first placement plate 21 during the replacement of the old curing bladder 5, thereby reducing the amount of steam used when the new curing bladder 5 is heated to the operating temperature, thereby achieving an energy-saving effect.

[0061] 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 a rotating shaft 24. The rotating shaft 24 is arranged perpendicular to the connecting rod 23 and is rotated and inserted into 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 into 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.

[0062] When the disassembly assembly 3 removes the old curing bladder 5 and places it on the second placement plate 22 at 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 onto the vertical plane to form a parallelogram structure, thereby ensuring that the first placement plate 21 and the second placement plate 22 remain horizontal during use. When the connecting rods 23 rotate 180 degrees, the first placement plate 21 and the new curing bladder 5 rotate to the replacement station 141, and the second placement plate 22 and the old curing bladder 5 rotate to the standby station 142. This allows the new and old curing bladders 5 to be reversed without having to adjust the position of the new curing bladder 5, thereby improving the accuracy of the reversal.

[0063] Reference Figure 4 、 Figure 5 To improve the stability and position accuracy of the new curing bladder 5 on the first placement plate 21, a positioning block 27 is fixed to the first placement plate 21. The positioning block 27 includes a positioning portion 271 and a guide portion 272. The positioning portion 271 is cylindrical and fits within the inner hole of the bottom flange plate assembly 52. When the curing bladder 5 is placed on the first placement plate 21, the positioning portion 271 engages with the bottom flange plate assembly 52, improving the accuracy of the curing bladder 5 on the first placement plate 21. The guide portion 272, located above the positioning portion 271 and having a conical shape, guides the positioning portion 271 into the inner hole of the bottom flange plate assembly 52, facilitating its insertion. A first permanent magnet 273 is embedded in the first placement plate 21 to attract the bottom flange plate assembly 52 and improve the stability of the new curing bladder 5 on the first placement plate 21.

[0064] Reference Figure 4 、 Figure 5 A clamping and unloading part 28 is provided on the first placement plate 21. The clamping and unloading part 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 fixed on the piston rod of each linear cylinder 281. The connecting rod 282 extends from the edge of the first placement plate 21 to the top of the first placement plate 21, and a second permanent magnet 283 is fixed at the end. The two second permanent magnets 283 respectively adsorb and fix the two support rods 54 on the new vulcanization bladder 5, and then the linear cylinder 281 drives the two connecting rods 282 away from each other, pulling the support rod 54 out of the molding groove 53.

[0065] Reference Figure 4 、 Figure 7The disassembly assembly 3 in this embodiment includes a rotating disassembly component 31 and a nut disassembly component 32. The rotating disassembly component 31 in this embodiment includes a second linear mechanism 311, a rotating mechanism 312 and a straight insertion mechanism 313.

[0071] 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 causes the second rod 3162 to 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.

A third permanent magnet 3223 is provided at the step between the hexagonal sleeve hole 3221 and the center hole 3222. The third permanent magnet 3223 is used to adsorb the removed fixed nut 64 to ensure the stability of the fixed nut 64.

[0074] When the first cylinder 3211 and the second cylinder 3111 drive the nut sleeve 322 and the disassembly rod 316 to change their positions, a distance sensor is used to control the distance moved by 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.

[0075] 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.

[0076] First, center positioning: The camera must be calibrated to obtain its intrinsic parameters (focal length, principal point coordinates, etc.) and extrinsic parameters (position vector and rotation matrix, etc.). These parameters are used to convert the image coordinate system into a three-dimensional space coordinate system. Feature points (such as corners and edges) are detected in the image, and matching algorithms are used to find the corresponding points of these feature points in different images or models. The feature point matching results are combined with the camera's intrinsic and extrinsic parameters to solve the camera's attitude (rotation and translation vectors) relative to the world coordinate system through geometric principles (such as the PnP problem, or Perspective-n-Point problem). In plane positioning, markers (such as ArUco markers) with known positions are usually placed on the plane. The camera determines its position on the plane by detecting these markers. The 2D image coordinates of the detected markers and their 3D coordinates in the world coordinate system, combined with the camera's intrinsic parameters, can be used, for example, using the cv2.solvePnP() function to solve the camera's attitude (rotation vector and translation vector). For targets on a plane, the target's coordinates can be determined by calculating the intersection of a ray from the camera to the target point with a known plane (such as the ground). This typically involves converting the target point in the camera coordinate system into the world coordinate system and calculating the intersection with the plane. Once the positions of the camera and target in the world coordinate system are determined, this information can be used to control the corresponding servo motors to drive the mobile frame to the specified position. This typically 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 movement path by comparing the actual position with the target position to ensure that it reaches the destination accurately.

[0077] 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, and the image Jacobian matrix is converted into a Cartesian space error. The PI controller is used to control the fourth motor 3233 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.

[0078] 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. 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. 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.
