Description

Technical Field

[0001] The invention relates to the field of tire dressing equipment, and in particular to a tire dressing equipment with a driving device inside. Background Art

[0002] Tires are important parts of motor vehicles and are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving. Therefore, they are required to have high load-bearing performance, traction performance, and cushioning performance. Therefore, strict inspection is required during the production process of tires. The manufacturing process of tires generally includes mixing process, extrusion process, bead process, calendering process, cutting process, molding process, vulcanization process and inspection process. Among them, the molding process combines various semi-finished products of the previous process according to the prescribed process, and after two moldings, the basic shape of the tire - the green tire is formed. After inspection, the green tire is transported to the vulcanization process, and the green tire is installed on the vulcanizer. After an appropriate time and suitable conditions in the mold, it is vulcanized into a finished tire. After that, the tire is sent to the inspection area for appearance inspection, uniformity inspection, dynamic balancing, balance inspection and other inspection processes.

[0003] During the processing of tires, burrs or waste residues will be generated, which will affect the quality inspection of tires. For example, when the tire is undergoing the vulcanization molding process, the green tire is loaded into the vulcanizer mold and will be extruded under high pressure and high temperature. After the vulcanization is completed, some rubber waste will remain at the joints of the tire surface. During the appearance inspection, this circle of excess waste needs to be removed before it can be evaluated as a qualified product. The current method of removing waste is manual trimming, which requires manual handling and rotation of the tire, manual inspection of the burr position and manual shoveling of the burr, and manual flipping of the tire to remove the rubber on the inner surface. The efficiency is low, the labor cost is high, and even improper operation may scratch the tire or the operator. At the same time, the quality of manual trimming is unstable and may damage the new tire.

[0004] The Chinese patent with the publication number "CN214773405U" and the name "Automatic burr removal equipment for tire production" discloses a device for removing burrs using a robot, which includes a cutting frame, on which a row of rotating rollers for driving the tire to rotate are provided, a blocking plate is provided along one end of the rotating roller, and both sides of the rotating roller are provided with straightening components for straightening the tire; an automatic cutting station is provided at the other end of the rotating roller along its rolling direction; a camera and a laser sensor are provided above the automatic cutting station.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0043] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] The embodiment of the present invention discloses a tire repairing device 100 with a driving device inside, which is used to clean burrs and other excess materials on the inner and outer surfaces of the tire. Figure 1 The tire dressing device 100 with a driving device inside includes a base plate 110, which is used to support various components of the entire tire dressing device. A pad 120 is provided on the base plate 110 for placing a tire. In this embodiment, the tire can be placed flat on the pad 120, that is, the axis of the tire is perpendicular to the horizontal plane. The pad 120 can rotate relative to the base plate 110 around its own central axis to facilitate the rotation of the tire during dressing. Exemplarily, the pad 120 is connected to the base plate 110 through a slewing support bearing, or through a structure similar to a slewing support bearing.

[0045] The backing plate 120 is provided with a clearance hole. For example, the shape of the clearance hole can be circular, square or other irregular shapes. After the tire is placed on the backing plate 120, the hole in the middle of the tire corresponds to the clearance hole.

[0046] The trimming equipment of this embodiment includes a driving device for driving the tire to rotate so that the inner and outer sides of the tire can be cleaned and trimmed during rotation. The driving device includes a rotating disk 145, which can move along the radial and axial direction of the pad 120 to be close to the inner surface of the tire sidewall or away from the inner surface of the tire sidewall. Specifically, when the rotating disk 145 is in the initial position, it is in the clearance hole of the pad 120. When working, the rotating disk 145 can move along the radial direction of the pad 120 to enter the tire or move out of the tire. That is, during the trimming operation, the rotating disk 145 can enter the tire along the opening of the tire bead, and then the rotating disk 145 moves axially and contacts the inner surface of the tire sidewall. It should be noted that the inner surface of the tire sidewall is the inner surface of the sidewall that contacts the tire and the pad 120. The rotating disk 145 can rotate along its own axis. When the rotating disk 145 rotates, the tire and the backing plate can be driven to rotate through friction, so that the burrs at different positions of the tire can be cleaned or trimmed.

[0047] Furthermore, a plurality of rotating disks 145 are provided, that is, at least two rotating disks 145 are provided in the clearance holes of the pad 120, and the rotating disks 145 are provided at intervals, so as to provide friction at different positions of the tire and drive the tire to rotate together. Preferably, the rotating disks 145 are provided at even intervals, such as when two rotating disks 145 are provided, they are provided at an interval of 180 degrees; when four rotating disks 145 are provided, they are provided at an interval of 90 degrees, so as to ensure that the tire is evenly stressed.

[0048] Furthermore, when the rotating disk 145 is in close contact with the inner surface of the sidewall of the tire to be tested, it forms a certain squeezing force on the tire together with the pad 120, so that the rotating disks 145 arranged at intervals can also position the tire at the same time to prevent the tire from shifting or falling during the rotation process. Each rotating disk 145 not only acts as a driving device to drive the tire to rotate, but also plays a role in positioning the tire, thereby improving the stability of the tire during trimming and ensuring the tire trimming effect.

[0049] Continue to refer to Figure 1, this embodiment includes a tool to trim the tire surface, and the tire surface includes the trimming of the inner surface and / or the outer surface, that is, only the inner surface or the outer surface of the tire can be trimmed, and it also includes trimming the inner surface and the outer surface of the tire at the same time. Exemplarily, the tool of the trimming equipment of this embodiment includes at least one first blade 143 and at least one second blade 153. The first blade 143 is arranged on the inner side of the pad 120, that is, the initial position of the first blade 143 is located in the clearance hole of the pad 120, and the first blade 143 can move along the radial direction of the pad 120 to contact the inner surface of the tire, which is used to clean the inner surface of the tire. The second blade 153 is arranged on the outer side of the pad 120, and the second blade 153 can move along the radial direction of the pad 120 to contact the outer surface of the tire, which is used to clean the outer surface of the tire. That is, the embodiment of the present application can trim the burrs on the trimmed tire surface and the outer surface of the tire respectively at the same time through the first blade 143 and the second blade 153, which can improve the trimming efficiency of the equipment.

[0050] The technical solution of this embodiment is to place the tire by setting a pad 120 that can rotate relative to the base, and to set a plurality of rotating disks 145 at intervals inside the clearance hole of the pad 120. The first blade 143 and the second blade 153 are respectively set on the inner edge and the outer edge of the pad 120, which can clean the inner side and the outer side of the tire. After the tire to be trimmed is placed on the pad 120, each rotating disk 145 moves toward the tire (including first radial movement and then axial movement, or first axial movement and then radial movement) to be close to the inner surface of the tire sidewall. When trimming the tire, each rotating disk 145 rotates around its own axis. Since the rotating disk 145 is in close contact with the inner surface of the tire sidewall, the rotating disk 145 can drive the tire to rotate through friction when rotating; at the same time, since the pad 120 can rotate relative to the bottom plate 110, each rotating disk 145 can drive the tire and the pad 120 to rotate relative to the bottom plate 110. The first blade 143 and the second blade 153 can clean different positions of the inner and outer surfaces of the rotating tire to achieve an efficient trimming effect. In this process, the rotating disk 145 plays a dual role of driving and positioning the tire at the same time. The functional integration increases the intensiveness of the equipment, simplifies the equipment structure, and reduces the equipment cost. In addition, the tire can be fixed and kept stable during trimming, thereby ensuring the trimming result.

[0051] When the tire is trimmed, each rotating disk 145 moves radially away from the tire, that is, the rotating disk 145 moves radially, breaks away from the contact with the inner side of the tire, and retracts into the clearance hole of the pad 120, which is convenient for unloading the trimmed tire and placing the next trimmed tire.

[0052] Reference Figure 1 and Figure 2The tire repairing device of this embodiment further includes a support plate 133, which is located in the clearance hole of the pad 120, that is, the diameter of the support plate 133 is smaller than the diameter of the clearance hole of the pad 120. The rotating disk 145 and the first blade 143 are both disposed on the support plate 133, and the support plate 133 can be rotated in the axial direction (such as Figure 1 The support plate 133 is provided with a first driving part 132 at the bottom of the support plate 133 along the axial direction, and the first driving part 132 can drive the support plate 133 to move axially in the clearance hole of the backing plate, thereby driving each rotating disk 145 and the first blade 143 to move axially to adjust the relative position with the tire to be trimmed in the axial direction, ensuring that the rotating disk 145 and the first blade 143 correspond to the opening of the tire bead, so that when the rotating disk 145 and the first blade 143 move radially, they can enter the interior of the tire through the opening of the tire bead.

[0053] Reference Figure 2 , the radial movement of the rotating disk 145 is driven by the second driving part 141, the second driving part 141 is arranged on the support plate 133, the output end of the second driving part 141 can be extended and retracted in the radial direction, and is connected to the driving disk 145 and / or the first blade 143, and is used to drive the rotating disk 145 and the first blade 143 to move in the radial direction. It can be understood that the number of the second driving parts 141 corresponds to the number of the rotating disks 145 and the first blades 143. That is, a plurality of second driving parts 141 are provided, which can be connected to each rotating disk 145 and each first blade 143 respectively; or one driving device can be connected to the rotating disk 145 and the first blade 143 at the same time. That is, one second driving part 141 drives the rotating disk 145 and the first blade 143 at the same time. Such a configuration can reduce the number of second driving parts 141.

[0054] For example, the number of the rotating disks 145 and the first blades 143 is the same, and the output end of each second driving part 141 is connected to a first mounting part 142, and the first mounting part 142 is provided with a rotating disk 145 and a first blade 143 (as shown in the attached figure). Figure 1As shown). Specifically, the first mounting portion 142 extends axially to a set length, the upper end of the first mounting portion 142 is connected to the output end of the second driving portion 141, and the rotating disk 145 is connected to the lower end of the first mounting portion 142 in the axial direction, that is, the first mounting portion 142 extends axially to form an L-shape with the second driving portion 141 extending radially. Since the axial dimension of the tire interior is greater than the axial distance at the tire bead opening, the first mounting portion 142 extends axially to a set length, which can ensure that the first mounting portion 142 can drive the rotating disk 145 to move radially through the tire bead opening to the interior of the tire, and can also achieve that after the first mounting portion 142 drives the rotating disk 145 to enter the tire interior, after moving a small distance in the axial direction, the rotating disk 145 can contact the inner surface of the tire sidewall, so as to drive the tire to rotate from the inside.

[0055] Furthermore, the rotating disk 145 is axially disposed below the first blade 143, so that the rotating disk 145 and the first blade 143 do not interfere with each other during operation, and the first blade 143 can cover the entire inner surface of the tire along the axial direction, ensuring that the entire inner surface of the tire is completely trimmed. In this embodiment, the rotating disk 145 and the first blade 143 are integrated into the first mounting portion 142, which can simplify the structure of the equipment and reduce costs.

[0056] Reference Figure 3 and Figure 4 , a fourth driving part 146 is provided on the first mounting part 142 corresponding to the rotating disk 145, and the output end of the fourth driving part 146 is connected to the rotating disk 145, and is used to drive the rotating disk 145 to rotate, so that the rotating disk 145 drives the tire to rotate through friction. Exemplarily, the rotating disk 145 includes a connecting shaft, and a bearing is provided on the first mounting part 142, and the connecting shaft of the rotating disk 145 is connected to the first mounting part 142 through the bearing. The fourth driving part 146 is fixedly arranged on the first mounting part, and its output end is connected to the connecting shaft of the rotating disk 145 to drive the rotating disk 145 to rotate. Exemplarily, the fourth driving part 146 can be a small motor, a motor, etc.

[0057] Furthermore, the rotating disk 145 is connected to the bottom of the first mounting portion 142, and the bottom of the outer circumference of the rotating disk 145 protrudes from the lower end surface of the first mounting portion 142, so that the outer circumference of the rotating disk 145 can contact the tire. Specifically, the rotating disk 145 can be arranged on any one of the two radial side surfaces of the first mounting portion 142, that is, the rotating disk can be arranged on the outer side surface of the first mounting portion 142 close to the tire in the radial direction (such as Figure 1 and Figure 2), or may be disposed on the inner side radially away from the tire. Or in another specific embodiment, a notch extending in the axial direction is disposed at the bottom of the first mounting portion 142, and the rotating disk 145 may be rotatably disposed in the notch. This embodiment does not limit the specific connection method between the rotating disk 145 and the first mounting portion 142.

[0058] In another embodiment, the rotating disk 145 and the first blade 143 may not be integrated into one component, such as the first mounting portion 142 of the present embodiment, but may be connected to driving devices respectively, and their movements may be controlled by respective driving devices.

[0059] Further, refer to Figure 3 , the first driving part 132 and the supporting plate 133 are arranged through the bottom plate 110, providing more axial space for the movement of the supporting plate 133. For example, a through hole is arranged on the bottom plate 110, and a connecting plate 131 extending a certain distance axially downward is connected to the lower surface of the bottom plate 110 at a position corresponding to the through hole, and the first driving part 132 is arranged on the connecting plate 131. With such an arrangement, the axial adjustment distance of the rotating disk 145 and the first blade 143 driven by the supporting plate 133 can be increased, thereby enabling the rotating disk 145 and the first blade 143 to have a wider range of adjustment relative to the tire, so that the equipment can be applied to tires of different specifications.

[0060] Furthermore, when the tire dressing equipment is not in use or the tire dressing process is completed, after each second driving part 141 drives each first mounting part 142 to retract radially, the first mounting part 142 is close to the outer side of the support plate 133, and the maximum radial outline size of the first mounting part 142 and all the components thereon is smaller than the inner diameter of the clearance hole of the pad 120. That is, the rotating disk 145 and the first blade 143 can be retracted along the radial direction with the first mounting part 142, and are radially located in the accommodation space between the support plate 133 and the pad 120. The accommodation space is defined by the clearance hole of the pad 120 to the through hole of the bottom plate 110 in the radial direction; the accommodation space extends from the surface of the pad 120 to the connecting plate 131 in the axial direction. The first driving part 132 can drive the support plate 133 and the second driving part 141, the first mounting part 142, the rotating disk 145 and the first blade 143 thereon to move axially into the accommodation space, so that the equipment is easy to store and components are prevented from being damaged.

[0061] Furthermore, the present embodiment also includes a support block 148, which is connected to the output end of the second driving part 141 and is slidably connected to the support plate 133 (correspondingly, a slide groove connected to the support block 148 is provided on the support plate 133). The support block 148 is used to support the output end of the second driving part 141 to prevent the first mounting part 142 from shaking when the second driving part 141 drives the first mounting part 142 to move, thereby ensuring stability during the tire trimming process.

[0062] Furthermore, the first mounting portion 142 is provided with a first blade groove 1421 for accommodating the first blade 143. The first mounting portion 142 is also provided with a third driving portion 144 connected to the first blade 143, and the third driving portion 144 can drive the first blade 143 to move out of the first blade groove 1421 radially or be received in the first blade groove 1421. When it is necessary to trim the inner side of the tire, the third driving portion 144 drives the first blade 143 to move it out of the first blade groove 1421, contact the tire, and perform trimming of burrs and waste materials on the inner surface of the tire. Before and after tire trimming, the first blade 143 can be moved by the third driving portion 144 to be received in the first blade groove 1421, so as to avoid accidental injury to the operator when placing and removing the tire, thereby improving the safety of operation.

[0063] Reference Figure 1 , Figure 3 and Figure 4 , the second mounting portion 152 is arranged on the outer edge of the pad 120, and is used to install the second blade 153. The fifth driving portion 151 is arranged on the bottom plate 110, and its output end is connected to the second mounting portion 152. The fifth driving portion 151 can drive the second mounting portion 152 to move radially. After the tire is placed, the fifth driving portion 151 drives the second mounting portion 152 to approach the outer side of the tire to prepare for the outer side of the tire. Further, the inner side of the second mounting portion 152 matches the shape of the outer side of the tire. That is, the side of the second mounting portion 152 close to the tire is arc-shaped, and the curvature of the arc can match the outer side of the tire, so that when the second mounting portion 152 moves to a position close to the outer side of the tire, a limit is provided for the tire. Specifically, the curvature of the side of the second mounting portion 152 is greater than or equal to the curvature of the outer side of the tire. After the second mounting portion 152 moves into place, a certain gap is left between it and the outer side of the tire, so as to form a limit for the tire while ensuring smooth rotation of the tire. The second mounting portion 152 assists the rotating disk 145 in limiting the position of the tire, so that the position of the tire remains stable during the trimming process to ensure the trimming effect.

[0064] Furthermore, the second mounting portion 152 is provided with a second blade groove 1521 for accommodating the second blade 153. The second mounting portion 152 is also provided with a sixth driving portion 154 connected to the second blade 153, and the sixth driving portion 154 can drive the second blade 153 to move out of the second blade groove 1521 radially or be received in the second blade groove 1521. When it is necessary to trim the outer side of the tire, the sixth driving portion 154 drives the second blade 153 to move out of the second blade groove 1521, contact the outer side of the tire, and perform trimming of burrs, etc. Before and after tire trimming, the second blade 153 can be moved by the sixth driving portion 154 to be received in the second blade groove 1521, so as to avoid accidental injury to the operator when placing and removing the tire.

[0065] In this embodiment, the second driving part 141, the first mounting part 142, a rotating disk 145 disposed on the first mounting part 142, a first blade 143, a third driving part 144, and a fourth driving assembly constitute the first tool assembly 140. The fifth driving part 151, the second mounting part 152, the second blade 153, and the sixth driving part 154 disposed on the outer edge of the pad 120 constitute the second tool assembly 150. The first tool assembly 140 and the second tool assembly 150 can be arranged in multiple groups along the circumferential direction, and the first tool assembly 140 and the second tool assembly 150 can be arranged correspondingly in the radial direction. For example, as shown in the attached Figure 1 As shown in , four sets of first tool assemblies 140 and second tool assemblies 150 are included, and the first tool assemblies 140 and second tool assemblies 150 are arranged correspondingly in the radial direction. In another embodiment, the first tool assemblies 140 and second tool assemblies 150 can be staggered with each other in the radial direction.

[0066] Continue to refer Figure 1 The first tool assembly 140 and the second tool assembly 150 are respectively provided with a first camera 147 and a second camera 155, which are respectively used to detect whether there are any burrs remaining on the inner surface and the outer surface of the tire, and the location of the remaining burrs, and then the rotating disk 145 is used to rotate the location of the tire with the burrs remaining to the first blade 143 or the second blade 153 for cleaning.

[0067] As a specific implementation, a first camera 147 may be provided on the first mounting portion 142 of a first tool assembly 140, so that at least one first camera 147 is used to monitor the inner side of the tire. A second camera 155 may be provided on the second mounting portion 152 of a second tool assembly 150, so that at least one second camera 155 is used to monitor the outer side of the tire. The first camera 147 and the second camera 155 may provide real-time feedback on the tire surface finishing, and all burrs may be finished in place to ensure the finishing effect.

[0068] As another specific embodiment, multiple cameras may be arranged on the inner and outer sides. For example, the first camera 147 is mounted on the first mounting portion 142, and the second camera 155 is mounted on the second mounting portion 152. The first camera 147 is mounted on one or both sides of the first mounting portion 142 of all first tool assemblies 140, and the second camera 155 is mounted on one or both sides of the second mounting portion 152 of all second tool assemblies 150. By arranging multiple groups of cameras, the surface condition of the tire can be detected more quickly, which is convenient for rapid and comprehensive detection.

[0069] Exemplarily, the first drive assembly, the second drive assembly, the third drive assembly, the fourth drive assembly, the fifth drive unit 151 and the sixth drive assembly are cylinders. The trimming device 100 of this embodiment further includes a control device, and the first to sixth drive assemblies, as well as the first camera 147 and the second camera 155 are all connected to the control device. When cameras are provided on the plurality of first mounting parts 142 and the plurality of second mounting parts 152, the control device can control the rotating disk 145 to drive the tire to rotate to the first blade 143 or the second blade 153 closest to the burr for trimming, thereby improving the tire trimming efficiency.

[0070] The following is a detailed description of the process when the above embodiment technical solution is used, so as to understand the embodiment technical solution in more detail:

[0071] In the initial state of the tire trimming device of this embodiment, each first blade 143 and the second blade 153 are respectively located in the corresponding first blade groove 1421 and the second blade groove 1521, and the support plate 133 and the second driving part 141, the first mounting part 142, the rotating disk 145 and the first blade 143 thereon are all in the initial state and located in the accommodation space. After the tire to be trimmed is placed on the pad 120, the first driving part 132 is started to drive the support plate 133 and the components thereon to move upward in the axial direction, so that the first mounting part 142 moves to a position corresponding to the opening of the tire bead. After that, each second driving part 141 is started to drive each first mounting part 142 to move radially toward the tire until the first mounting part 142 moves inside the tire through the opening of the tire bead. Then, the support plate 133 is driven to move downward in the axial direction by the first driving part 132, so that each rotating disk 145 is close to the bottom of the inner side of the tire, the tire is stably positioned, and preparation is made for driving the tire to rotate. The fifth driving portion 151 drives the second mounting portion 152 to move radially toward the tire until the second mounting portion 152 is close to the outer side of the tire.

[0072] Next, the fourth driving unit 146 drives the first blade 143 to extend out of the first blade groove 1421 to contact the inner side of the tire, and the sixth driving unit 154 drives the second blade 153 to extend out of the second blade groove 1521 to contact the inner side of the tire. The fourth driving unit 146 drives the rotating disk 145 to rotate, driving the tire and the pad 120 to rotate relative to the bottom plate 110, that is, to rotate relative to the first blade 143 and the second blade 153. During the rotation of the tire, the first blade 143 can trim the burrs and debris on the inner side of the tire, and the second blade 153 can trim the burrs and debris on the outer side of the tire. At the same time, the first camera 147 and the second camera 155 detect the inner surface and the outer surface of the tire respectively. If there are still untrimmed burrs, the information is fed back to the control device, and the control device controls the rotating disk 145 to rotate, so that the tire continues to rotate, and the untrimmed part is rotated to the position of the first blade 143 or the second blade 153 for trimming. If the first blade 143 or the second blade 153 is a certain distance away from the burr, the fourth driving unit 146 and / or the sixth driving unit 154 can drive the first blade 143 and / or the second blade 153 to move a certain distance toward the tire, so as to trim the burr on the tire surface.

[0073] After the trimming is completed, the fourth driving unit 146 drives the first blade 143 to retract into the first blade groove 1421, and the sixth driving unit 154 drives the second blade 153 to retract into the second blade groove 1521. The first driving unit 132 drives the support plate 133 to move upward in the axial direction, so that the position of the first mounting portion 142 corresponds to the opening of the tire bead. The second driving units 141 are started to drive the first mounting portions 142 to move radially, so that the first mounting portions 142 are moved out of the tire through the opening of the tire bead. At the same time, the fifth driving unit 151 drives the second mounting portion 152 to move radially, so that the second mounting portion 152 is away from the tire, and then the trimmed tire is unloaded.

[0074] The technical solution of this embodiment can ensure that the tire remains stable during the trimming process, achieve efficient trimming of the inner and outer sides of the tire, and ensure the final trimming effect through the linkage between the first camera 147 and the second camera 155 and the first blade 143 and the second blade 153.
