Description

Technical Field

[0001] This utility model relates to the field of tire molding, and more specifically, to a tire rubber positioning device and a molding machine. Background Technology

[0002] Currently, the process of bonding annular strip rubber compound to semi-finished tire carcasses involves manually placing the strip onto a transfer ring and pre-positioning it manually. During bonding, a support arm is pulled away from the rubber compound without power to facilitate bonding. This method is inefficient and cannot guarantee accuracy. Furthermore, the friction from the unpowered pulling of the support arm during bonding on the drum is significant, causing the rubber compound to be easily pulled off-center and deformed at the bonding position. This results in poor positioning accuracy, leading to poor tire quality and significantly reducing production efficiency and yield. Utility Model Content

[0003] The main purpose of this invention is to provide a tire rubber positioning device and a molding machine to solve the problem of poor rubber positioning accuracy in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a tire rubber positioning device is provided, comprising a transfer ring and a conveying assembly. The transfer ring is movably disposed and has a support arm for supporting the rubber material. At least a portion of the conveying assembly is movably disposed on the support arm and has a conveying plane for conveying the rubber material. After the transfer ring moves the rubber material to the mating position in a first direction, the transfer ring moves in a second direction opposite to the first direction, while the conveying assembly on the support arm conveys the rubber material in the first direction. A predetermined ratio is maintained between the motion parameters of the transfer ring and the motion parameters of the conveying assembly to keep the rubber material in the mating position.

[0005] Furthermore, the conveying assembly includes: a plurality of rolling elements and a rolling drive element, wherein the rolling elements are movably and rollably disposed on the support arm, and at least some of the rolling elements are arranged along the length direction of the support arm; the rolling drive element is drivenly connected to the rolling elements and drives the rolling elements to move along the length direction of the support arm.

[0006] Furthermore, the rolling elements have multiple rows, each row of rolling elements extends along the length of the support arm, and each row of rolling elements is arranged circumferentially on the outer side of the support arm along the transfer ring.

[0007] Furthermore, the support arm has a position-adjustable positioning plate located at the end of the support arm away from the mating position and on the conveying path of the conveying assembly. The positioning plate has a positioning surface on the side facing the mating position. When the conveying assembly conveys the adhesive in the second direction, the end face of the adhesive abuts against the positioning surface.

[0008] Furthermore, the tire rubber positioning device also includes a detection element located on the transfer ring or support arm and electrically connected to the conveying assembly. When the detection element detects that the rubber has reached the placement position, the conveying assembly conveys the rubber in a second direction to pre-position the rubber.

[0009] Furthermore, the tire rubber positioning device also includes a clamping ring with a movable pressure roller. When the rubber is in the bonding position, the pressure roller presses against the outer surface of the rubber.

[0010] Furthermore, the pressure rollers are movably arranged along the radial direction of the clamping ring, and there are multiple pressure rollers. Each pressure roller is arranged at intervals along the circumference of the clamping ring. The clamping ring is movably arranged, and the movement trajectory line of the clamping ring is parallel to the first direction.

[0011] Furthermore, the support arm is movably arranged radially along the transfer ring, there are multiple support arms, each support arm is spaced apart circumferentially along the transfer ring, there are multiple conveying components, and each support arm is equipped with a conveying component, and the conveying components move synchronously with each other.

[0012] Furthermore, the tire rubber positioning device also includes a transfer ring drive component, which is connected to the transfer ring drive and drives the transfer ring to move axially.

[0013] According to another aspect of the present invention, a molding machine is provided, including the above-mentioned tire rubber positioning device.

[0014] By applying the technical solution of this utility model, the movement direction of the transfer ring is set to be opposite to that of the conveying component, and the movement parameters of the two are kept in a predetermined ratio. This allows the influence of the transfer ring's movement on the rubber material and the influence of the conveying component's movement on the rubber material to cancel each other out. At the same time, the support arm can gradually move away from the rubber material. In this way, the contact position between the rubber material and the conveying component remains relatively stationary, while the contact area between the conveying component and the rubber material gradually decreases until the support arm is pulled out from under the rubber material. During this process, the rubber material can always remain in the bonding position, thereby avoiding problems such as rubber material deformation and displacement caused by excessive friction during the separation of the support arm from the rubber material. This improves the bonding accuracy of the rubber material on the drum, thereby improving tire production efficiency and processing quality. Attached Figure Description

[0027] To address the problem of poor rubber material positioning accuracy in existing technologies, this invention provides a tire rubber material positioning device and a molding machine.

[0028] A tire rubber positioning method includes: rubber 60 being supported on a support arm 11 of a transfer ring 10; the transfer ring 10 moving in a first direction and moving the rubber 60 to a mating position; the transfer ring 10 moving in a second direction opposite to the first direction; and a conveying assembly 20 on the support arm 11 conveying the rubber in the first direction, wherein the motion parameters of the transfer ring 10 and the motion parameters of the conveying assembly 20 are maintained in a predetermined ratio to keep the rubber 60 in the mating position.

[0029] In this embodiment, the movement direction of the transfer ring 10 is opposite to that of the conveying component 20, and their movement parameters are kept in a predetermined ratio. This allows the effects of the movement of the transfer ring 10 on the rubber material 60 and the movement of the conveying component 20 on the rubber material 60 to cancel each other out. At the same time, the support arm 11 can gradually move away from the rubber material 60. In this way, the contact position between the rubber material 60 and the conveying component 20 remains relatively stationary, while the contact area between the conveying component 20 and the rubber material 60 gradually decreases until the support arm 11 is pulled out from under the rubber material 60. During this process, the rubber material 60 can always remain in the bonding position, thereby avoiding problems such as deformation and displacement of the rubber material 60 caused by excessive friction during the separation of the support arm 11 from the rubber material 60. This improves the bonding accuracy of the rubber material 60 onto the drum 70, thereby improving tire production efficiency and processing quality.

[0030] It should be noted that the first direction in this embodiment refers to the direction of the transfer ring 10 near the mating position, that is... Figure 3 The first direction is from left to right; the second direction refers to the direction in which the transfer ring 10 moves away from the mating position, that is... Figure 3 The direction from right to left.

[0031] In this embodiment, the predetermined ratio includes: the movement speed of the transfer ring 10 along the first direction is equal to the movement speed of the conveying assembly 20 along the second direction. This ensures that the influence of the movement of the transfer ring 10 on the position of the rubber material 60 and the influence of the movement of the conveying assembly 20 on the position of the rubber material 60 can cancel each other out, thereby maintaining the relative stillness of the contact position between the rubber material 60 and the conveying assembly 20. This avoids deformation and displacement of the rubber material 60 caused by excessive friction, thereby improving the positioning accuracy of the rubber material 60. Specifically, the movement direction of the transfer ring 10 along the first direction is the direction in which the support arm 11 moves away from the rubber material 60, and the movement direction of the conveying assembly 20 along the second direction is the opposite direction of the movement direction of the support arm 11. In this embodiment, the conveying component 20 is mounted on the support arm 11. Therefore, the conveying component 20 moves with the support arm 11 relative to the rubber material 60 in a first direction. At the same time, the conveying component 20 also moves relative to the support arm 11 in a second direction. Thus, when the support arm 11 and the conveying component 20 move in opposite directions and at the same speed, the part of the conveying component 20 that contacts the rubber material 60 is stationary relative to the rubber material 60. This allows the influence of the movements of the support arm 11 and the conveying component 20 on the position of the rubber material 60 to cancel each other out, thereby avoiding the deformation and displacement of the rubber material 60 and improving the positioning accuracy of the rubber material 60.

[0032] In this embodiment, the tire rubber positioning method further includes a pre-positioning process before the transfer ring 10 moves to the contact position. The pre-positioning process includes: after the rubber 60 is supported on the support arm 11, the conveying component 20 conveys it in a second direction, and the rubber 60 abuts against the positioning surface of the support arm 11 to position the rubber 60, thereby improving the pre-positioning accuracy of the rubber 60. Specifically, in this embodiment, after the rubber 60 is supported on the support arm 11, the conveying component 20 can drive the rubber 60 to move towards the positioning surface and until it abuts against the positioning surface. The axial position of the rubber 60 is positioned by the movement of the conveying component 20 and the abutment of the positioning surface, thus avoiding the inaccurate positioning problem caused by inconsistent cylinder strokes in the traditional method of pushing the rubber 60 with a cylinder. Furthermore, it eliminates the need for manual positioning, thereby not only improving the pre-positioning accuracy of the rubber 60 but also effectively reducing the labor intensity of the operators.

[0033] In this embodiment, the tire rubber positioning method further includes: when the rubber 60 is supported on the support arm 11, the rubber 60 triggers the detection element 30, the detection element 30 sends a positioning signal to the conveying assembly 20, the conveying assembly 20 receives the positioning signal and conveys the rubber 60 in a second direction, thereby further improving the positioning accuracy of the rubber 60 and the automation level of the pre-positioning process. Specifically, the detection element 30 can detect the presence or absence of the rubber 60 and whether the rubber 60 is in position. When the rubber 60 is supported on the support arm 11 but does not abut against the positioning surface of the support arm 11, the detection element 30 performs a detection and causes the conveying assembly 20 to move the rubber 60 closer to the positioning surface, thereby ensuring that the rubber 60 can abut against the positioning surface, thus ensuring the pre-positioning accuracy of the rubber 60.

[0034] In this embodiment, there are multiple support arms 11, and the tire rubber positioning method further includes: the conveying components 20 on each support arm 11 always move synchronously. Specifically, each conveying component 20 can drive the rubber 60 to move at different positions in the circumferential direction. When each conveying component 20 moves synchronously, it can drive the rubber 60 to move at different positions in the circumferential direction synchronously, thereby ensuring the consistency of the axial position of each position of the rubber 60 in the circumferential direction, so as to ensure the pre-positioning accuracy of the rubber 60 on the support arm 11 and the accurate positioning at the bonding position.

[0035] In this embodiment, the tire rubber positioning method further includes: before the rubber 60 is supported on the support arm 11, the support arm 11 contracts towards the center of the transfer ring 10, the rubber 60 is placed on the outer side of the support arm 11, and the support arm 11 expands away from the center of the transfer ring 10, supporting the rubber 60. Thus, when the rubber 60 needs to be placed on the support arm 11, the support arms 11 can move closer to each other, making the diameter of the ring formed by each support arm 11 smaller, thereby facilitating the operator to place the rubber 60 on the support arm 11. After the rubber 60 is placed, the support arms 11 move further apart, making the diameter of the ring formed by each support arm 11 larger to accommodate the diameter of the rubber 60, supporting the rubber 60 on the outer surface of the support arm 11, thereby keeping the rubber 60 ring-shaped and preventing the rubber 60 from deforming or falling off.

[0036] In this embodiment, the tire rubber positioning method further includes: before the transfer ring 10 moves in the second direction, the pressure roller 41 of the clamping ring 40 retracts towards the center of the clamping ring 40 and abuts against the outer surface of the rubber 60; when the transfer ring 10 moves in the second direction, the pressure roller 41 keeps pressing against the rubber 60 until the conveying assembly 20 completely exits the inner surface of the rubber 60. In this way, the pressure roller 41 of the clamping ring 40 can press the rubber 60 radially, fixing the rubber 60 between the pressure roller 41 and the drum 70. This ensures that when the transfer ring 10 moves away from the rubber 60, even if there is friction between the rubber 60 and the conveying assembly 20, the rubber 60 will not move away from the drum 70 with the transfer ring 10, thus ensuring that the axial position of the rubber 60 remains unchanged, and thereby ensuring the positioning accuracy of the rubber 60 at the bonding position.

[0037] It should be noted that the axial direction mentioned in this embodiment refers to the axial direction of the transfer ring 10, which is also the axial direction of the rubber material 60. The clamping ring 40 in this embodiment is coaxially arranged with the transfer ring 10, and therefore is also the axial direction of the clamping ring 40.

[0038] like Figures 1 to 6 As shown, this embodiment also provides a tire rubber positioning device, including a transfer ring 10 and a conveying assembly 20. The transfer ring 10 is movably arranged and has a support arm 11 for supporting the rubber 60. At least a portion of the conveying assembly 20 is movably arranged on the support arm 11 and has a conveying plane for conveying the rubber 60. After the transfer ring 10 drives the rubber 60 to the bonding position in a first direction, the transfer ring 10 moves in a second direction opposite to the first direction. At the same time, the conveying assembly 20 on the support arm 11 conveys the rubber in the first direction. The motion parameters of the transfer ring 10 and the motion parameters of the conveying assembly 20 maintain a predetermined ratio so that the rubber 60 is kept in the bonding position.

[0039] The tire rubber positioning device of this embodiment adopts the above-described tire rubber positioning method. By setting the transfer ring 10 and the conveying component 20 to move in different directions, the transfer ring 10 and the conveying component 20 are moved away from the rubber 60 as a whole. At the same time, it can ensure that the part of the conveying component 20 in contact with the rubber 60 remains relatively stationary relative to the rubber 60. By gradually reducing the contact area between the conveying component 20 and the rubber 60, the conveying component 20 and the rubber 60 are separated. During this process, the rubber 60 can always be kept in the contact position, thereby avoiding problems such as displacement and deformation of the rubber 60 caused by excessive friction during the separation of the support arm 11 from the rubber 60. This improves the positioning accuracy of the rubber 60 in the contact position, thereby improving the tire production efficiency and processing quality.

[0040] It should be noted that the bonding position in this embodiment refers to the position where the rubber material 60 moves to the outer periphery of the drum 70, ready to bond with the tire blank already set on the drum 70. Bonding and pressing of the rubber material 60 can be achieved at this position. Of course, the tire rubber material positioning device and method of this embodiment are not limited to this, and are also applicable to the pre-positioning and bonding of other annular strip rubber materials.

[0041] like Figure 6 As shown, in this embodiment, the conveying assembly 20 includes a rolling conveying drive 22 and a plurality of rolling elements 21. The rolling elements 21 are movably and rollably disposed on the support arm 11, and at least a portion of the rolling elements 21 are arranged along the length direction of the support arm 11. The rolling conveying drive 22 is drivenly connected to the rolling elements 21 and drives the rolling elements 21 along the length direction of the support arm 11. Specifically, in this embodiment, the rolling elements 21 are disposed on the side of the support arm 11 away from the axis of the transfer ring 10, and the side of the rolling elements 21 away from the center of the transfer ring 10 serves as a conveying plane, thereby supporting the inner circumferential surface of the rubber material 60. Optionally, the rolling element 21 is made of rolling steel balls, which are arranged along the moving direction of the conveying assembly 20. The rolling conveying drive 22 drives the rolling steel balls to move synchronously, so that different positions of the rubber material 60 can remain relatively stationary relative to different rolling elements 21. This prevents the rubber material 60 from deforming during the conveying process. Compared with the unpowered conveying assembly 20, this greatly improves the pre-positioning accuracy of the rubber material 60 on the support arm 11 and the positioning accuracy at the bonding position, thereby improving the tire yield and greatly promoting the advancement of tire manufacturing technology. It should be noted that the length direction of the support arm 11 is the axial direction of the transfer ring 10, and also the moving direction of the conveying assembly 20.

[0042] In this embodiment, the rolling conveying drive 22 is mounted on the support arm 11. A ball track extending axially along the transfer ring 10 is provided on the surface of the support arm 11 away from the center of the transfer ring 10. The rolling element 21 is disposed within the ball track, enabling the rolling element 21 to drive the rubber material 60 to move along the extension direction of the ball track. Combined with the rolling characteristic of the rolling element 21 itself, the friction force on the rubber material 60 is further reduced. Thus, when the transfer ring 10 drives the rubber material 60 to the bonding position, and the support arm 11 is pulled out from between the rubber material 60 and the drum 70, the transfer ring 10 moves in the second direction, while the rolling element 21 moves relative to the transfer ring 10 in the first direction. For the rubber material 60, the movement of the transfer ring 10 and the movement of the rolling element 21 cancel each other out, so that the part of the conveying plane that contacts the rubber material 60 only has a reduced contact area, while the contacting part always remains relatively stationary, thereby preventing the rubber material 60 from deforming due to friction or even deviating from the bonding position. Depending on actual needs, when relative displacement occurs between the conveying plane and the rubber material 60, the rolling characteristic of the rolling element 21 can greatly reduce the friction between the rubber material 60 and the conveying plane, thereby reducing the deformation of the rubber material 60. Optionally, the rolling conveying drive element 22 can be a servo motor.

[0043] In this embodiment, the rolling elements 21 are arranged in multiple rows, with each row extending along the length of the support arm 11. Each row of rolling elements 21 is arranged circumferentially on the outer side of the support arm 11 along the transfer ring 10, thereby further reducing the frictional force on the adhesive material 60, thus minimizing deformation of the adhesive material 60 and improving the bonding accuracy of the adhesive material 60. Specifically, considering better support for the adhesive material 60, the conveying plane has a certain width. In this embodiment, multiple rolling elements 21 are arranged along the width direction of the conveying plane. Correspondingly, the support arm 11 is provided with multiple ball bearing tracks extending axially along the transfer ring 10 to cooperate with the multiple rows of rolling elements 21. The rolling conveying drive 22 drives the multiple rows of rolling elements 21 to move synchronously. The width direction of the conveying plane refers to the direction in which the conveying plane extends circumferentially along the transfer ring 10.

[0044] In this embodiment, the support arm 11 has a position-adjustable positioning plate 111. The positioning plate 111 is located at the end of the support arm 11 away from the contact position and on the conveying path of the conveying assembly 20. The positioning plate 111 has a positioning surface on the side facing the contact position. When the conveying assembly 20 conveys the adhesive 60 in the second direction, the end face of the adhesive 60 abuts against and is positioned on the positioning surface. Specifically, in this embodiment, the positioning surface extends radially along the transfer ring 10, thereby enabling the positioning of the axial position of the adhesive 60. The positioning plate 111 can be configured as an L-shape, with the L-shape consisting of a first segment and a second segment. The first segment extends axially along the transfer ring 10 and is axially movably connected to the support arm 11. The second segment extends radially along the transfer ring 10, with the side of the second segment away from the first segment serving as a positioning surface. The positioning plate 111 also includes a positioning screw. The second segment has a hole through which the positioning screw passes. The positioning screw passes through the second segment and is movably connected to the support arm 11. The axial position of the positioning plate 111 can be adjusted by the positioning screw, thereby ensuring that the positioning surface is in the correct axial position, thereby improving the pre-positioning accuracy of the adhesive 60, and further improving the positioning accuracy of the adhesive 60 at the bonding position. In this way, when the rolling conveying drive 22 of the conveying assembly 20 drives the rolling element 21 to bring the rubber material 60 into contact with the positioning surface, the rubber material 60 is pre-positioned on the support arm 11. When the rolling conveying drive 22 of the conveying assembly 20 drives the rolling element 21 to move in the opposite direction and at the same speed as the transfer ring 10, the rubber material 60 moves away from the positioning surface and remains in the bonding position, thereby achieving precise positioning of the rubber material 60 in the bonding position.

[0045] In this embodiment, the tire rubber positioning device further includes a detection element 30, which is located on the transfer ring 10 or the support arm 11 and is electrically connected to the conveying assembly 20. When the detection element 30 detects that the rubber 60 has been placed, the conveying assembly 20 conveys the rubber 60 in a second direction to pre-position the rubber 60. Specifically, as Figure 1 As shown, in this embodiment, the detection element 30 is mounted on the support arm 11. The detection element 30 can detect the presence and position of the adhesive material 60. When the adhesive material 60 is placed on the support arm 11, the detection element 30 detects the placement of the adhesive material 60. The rolling conveying drive 22 drives the rolling element 21 to move the adhesive material 60 towards the positioning surface until the adhesive material 60 abuts against the positioning surface. After the detection element 30 detects that the adhesive material 60 is in place, the rolling element 21 stops moving, and the adhesive material 60 is conveyed into place, thereby achieving pre-positioning. This process does not require manual positioning, has a high degree of automation, reduces the workload of operators, and improves positioning accuracy and production efficiency.

[0046] In this embodiment, the tire rubber positioning device further includes a clamping ring 40, which has a movably disposed pressure roller 41. When the rubber 60 is in the bonding position, the pressure roller 41 presses against the outer surface of the rubber 60, thereby fixing the position of the rubber 60 and ensuring that the position of the rubber 60 on the drum 70 does not shift, thus preventing the rubber 60 from being displaced by external forces and affecting the bonding quality. Optionally, the pressure roller 41 can be configured as an L-shaped pressure plate, with a first segment and a second segment forming the L-shape. The second segment is disposed on the side of the first segment near the center of the clamping ring 40, and the side of the second segment near the center of the clamping ring 40 has a pressing surface for pressing the rubber 60. When the pressure roller 41 presses against the rubber material 60, the pressing surface abuts against the outer surface of the rubber material 60. The plate-shaped second segment ensures a certain pressing area between the pressure roller 41 and the rubber material 60, thereby guaranteeing the effectiveness of the pressing and preventing the position of the rubber material 60 from shifting when the support arm 11 is pulled out from between the rubber material 60 and the drum 70. Simultaneously, the L-shaped pressure roller 41 also facilitates the clamping ring 40 to perform other functions such as clamping and positioning the rubber material 60, providing possibilities for the multi-functional application of the clamping ring 40. Of course, the pressure roller 41 can also be configured as a cylindrical column, with its axis parallel to the axis of the clamping ring 40. This increases the contact area between the pressure roller 41 and the outer surface of the rubber material 60, ensuring the effectiveness of the pressing. It should be noted that the inner surface of the rubber material 60 refers to the circumferential surface of the rubber material 60 near the axis, and the outer surface of the rubber material 60 refers to the circumferential surface of the rubber material 60 away from the axis.

[0047] In this embodiment, the pressure rollers 41 are radially movable along the clamping ring 40. Multiple pressure rollers 41 are arranged at intervals along the circumference of the clamping ring 40, allowing the pressure rollers 41 to press the rubber material 60 at different positions circumferentially, thus ensuring uniform clamping of the rubber material 60 and preventing deformation. The tire rubber positioning device in this embodiment also includes a pressure roller 41 rolling conveying drive 22, which is mounted on the clamping ring 40 and driven by the pressure rollers 41. When the rubber material 60 moves to the bonding position, the pressure roller 41 rolling conveying drive 22 drives the pressure rollers 41 to contract radially along the clamping ring 40 to compact the rubber material 60, ensuring that the position of the rubber material 60 on the drum 70 does not shift. When the pressure rollers 41 need to avoid the drum 70 and the rubber material 60, the pressure roller 41 rolling conveying drive 22 drives the pressure rollers 41 to move away from each other. Optionally, the roller 41 rolling conveyor drive 22 can be a telescopic cylinder.

[0048] In this embodiment, the clamping ring 40 is movably configured, and the movement trajectory of the clamping ring 40 is parallel to the first direction. Thus, the clamping ring 40 can move axially to the bonding position of the rubber material 60, causing the pressure roller 41 to compact the outer surface of the rubber material 60, thereby achieving a pressing effect on the rubber material 60. Furthermore, after the rubber material 60 is bonded, the clamping ring 40 can also remove the tire and transfer it to the next process, thus fulfilling the function of tire transfer.

[0049] In this embodiment, the support arms 11 are radially movable along the transfer ring 10. Multiple support arms 11 are arranged at circumferential intervals along the transfer ring 10, forming a ring to support the adhesive material 60. Correspondingly, multiple detection elements 30 can also be provided, each corresponding to one of the support arms 11, enabling the detection elements 30 to detect the presence or absence of adhesive material 60 on each support arm 11 and its position. Specifically, the transfer ring 10 in this embodiment also includes a ring body, a swing arm 12, and a swing arm drive element 13. The ring body serves as a carrier for the swing arm 12, swing arm drive element 13, and support arms 11, and can drive the swing arm 12, swing arm drive element 13, and support arms 11 to move axially. The swing arm drive element 13 is disposed on the ring body and is drivenly connected to the swing arm 12. Figure 2 As shown, one end of the swing arm 12 is connected to the swing arm drive 13, and the other end is connected to the support arm 11. Thus, the swing arm drive 13 drives the swing arm 12 to rotate around the center of the ring, and the swing arm 12 causes the support arm 11 to contract or expand radially along the ring. When the adhesive 60 needs to be placed on the support arm 11, each support arm 11 contracts radially, and then the adhesive 60 is placed onto the ring formed by the support arm 11 manually or by other mechanisms. Then, the support arm 11 expands radially, thereby supporting the adhesive 60 into a ring shape, facilitating the conveying of the adhesive 60 and preventing deformation. Simultaneously, the detection element 30 can detect the placement of the adhesive 60, facilitating the axial movement of the transfer ring 10 to convey the adhesive 60. Considering that the adhesive 60 can maintain an approximately ring shape when supported on the support arm 11, this embodiment provides eight support arms 11, and correspondingly, eight conveying components 20 and eight detection elements 30. Optionally, the swing arm drive 13 can be a servo motor. Of course, the connection method between the support arm 11 and the ring body is not limited to this. It is sufficient to enable the support arm 11 to move radially along the ring body, and at the same time enable the ring body to drive the support arm 11 to move axially.

[0050] In this embodiment, there are multiple conveying components 20, and each support arm 11 is provided with a conveying component 20. The conveying components 20 move synchronously. On the one hand, when the conveying component 20 conveys the adhesive 60 for pre-positioning, different positions of the adhesive 60 in the circumferential direction can move simultaneously, so that the circumferential positions of the adhesive 60 can simultaneously abut against the positioning surface, thereby improving the positioning accuracy of the adhesive 60 and improving the working efficiency of the pre-positioning of the adhesive 60. On the other hand, when the transfer ring 10 moves away from the clamping ring 40 in the second direction and the conveying component 20 moves in the first direction to abut against the movement of the transfer ring 10, the synchronous movement of each conveying component 20 can make the positions of the adhesive 60 in the circumferential direction evenly stressed, thereby avoiding deformation of the adhesive 60 and further improving the bonding accuracy of the adhesive 60.

[0051] The tire rubber positioning device in this embodiment further includes a transfer ring drive 50, which is drivenly connected to the transfer ring 10 and drives the transfer ring 10 to move axially, thereby enabling the transfer ring 10 to move along a first direction and a second direction. Optionally, the transfer ring drive 50 may be a servo motor.

[0052] like Figure 3 , Figure 4 , Figure 5As shown, using the above-mentioned tire rubber positioning device, the tire rubber positioning method in this embodiment is as follows: 1. Pre-positioning of rubber 60 on support arm 11: The swing arm drive 13 drives the swing arm 12 to move, causing the eight sets of support arms 11 to rotate around the center of the transfer ring 10, thereby reducing the annular diameter formed by each support arm 11; the operator or robot places the rubber 60 on the support arm 11; the swing arm drive 13 drives the swing arm 12 to expand the annular diameter formed by each support arm 11, thereby supporting the rubber 60; the rolling conveying drive 22 of the conveying assembly 20 drives the rubber 60 to move along the second direction; the detection switch detects the position of the rubber 60, and the rolling conveying drive 22 of the conveying assembly 20 adjusts the position of the rubber 60 until the rubber 60 abuts against the positioning surface on each support arm 11. 2. Precise positioning of the rubber material 60 at the bonding position: After the rubber material 60 is positioned on the support arm 11, the transfer ring 10 moves along the first direction toward the drum 70 to bring the rubber material 60 to the bonding position; the swing arm drive 13 drives the support arm 11 and causes the diameter of the rubber material 60 to decrease, ensuring that the rubber material 60 is in complete contact with the tire blank on the drum 70; the pressure rollers 41 of the clamping ring 40 move closer to each other under the drive of the pressure roller 41 rolling conveying drive 22 to compact the rubber material 60 and the tire blank; the transfer ring 10 moves along the second direction... The direction is away from the drum 70, and at the same time, the rolling conveying drive 22 of the conveying assembly 20 drives the rolling element 21 to move along the first direction, and the moving speed of the transfer ring 10 is the same as the moving speed of the rolling element 21; after the support arm 11 is completely pulled out and separated from the tire blank, the pressure roller 41 runs and rolls the rubber material 60. The pressure roller 41 here can be the pressure roller 41 of the clamping ring 40 or the pressure roller of other devices, depending on actual needs. After the rubber material 60 is rolled, the clamping ring 40 takes away the tire and transfers it to the next process.

[0053] This embodiment also provides a molding machine, including the above-mentioned tire rubber positioning device, and uses the above-mentioned tire rubber positioning method to achieve the positioning of the rubber 60, thereby reducing the deformation of the rubber 60 and improving the bonding accuracy of the rubber 60, and improving the pre-positioning accuracy of the rubber 60.
