Description

Technical Field

[0001] This application relates to the field of tire manufacturing technology, and in particular to a positioning and fixing frame for tire blank vulcanization. Background Technology

[0002] In tire manufacturing, tire carcass vulcanization is a critical process, and the accuracy of the carcass's transport and positioning before entering the vulcanization unit directly affects the vulcanization quality. Existing tire carcass transport equipment typically uses a robotic arm to grab the carcass from a traditional conveyor and place it on the vulcanization machine for vulcanization. However, with the robotic arm's gripping position fixed on the traditional conveyor, displacement of the carcass during transport can lead to positional deviations when it enters the vulcanization unit, increasing the defect rate. Utility Model Content

[0003] To address the problem of easy gripping of the tire blank during the transport of traditional conveying mechanisms, this utility model provides a method comprising: a conveying bracket and a fixing bracket.

[0004] The conveying support is a hollow plate-shaped structure with multiple rotatable conveying guide rollers along its length, and the multiple conveying guide rollers rotate in the same direction.

[0005] There are two fixed supports, located on both sides of the conveying support along its length. The two fixed supports can move towards or away from each other and are suitable for clamping the tire blank on the conveying support to the center position of the conveying support in the width direction.

[0006] In one possible implementation, the two fixed supports are spaced at the same distance from the conveying support.

[0007] In one possible implementation, the movement direction of the two fixed supports is perpendicular to the length direction of the conveying support.

[0008] In one possible implementation, the fixing bracket includes: a guide rail, a mounting bracket, a hydraulic cylinder, and a fixing gripper;

[0009] The guide rail is disposed below the conveying bracket, and the linear motion direction of the guide rail is perpendicular to the conveying direction of the conveying bracket.

[0010] The mounting bracket is slidably mounted on the guide rail, and the mounting bracket is vertically mounted with its top positioned above the conveying bracket;

[0011] The hydraulic cylinder is connected to the mounting bracket and drives the mounting bracket to reciprocate.

[0012] The fixing claw is disposed on the top of the mounting bracket and moves towards each other with the two mounting brackets, clamping the tire blank at the center position in the width direction of the conveying bracket.

[0013] In one possible implementation, the fixing claw is a plate-like structure with an arc, including a first plate, a second plate, and a third plate.

[0014] The first plate, the second plate, and the third plate are connected in sequence;

[0015] The first plate and the third plate are located on the same side of the second plate;

[0016] The angle between the first plate and the second plate is equal to the angle between the third plate and the second plate; and

[0017] The fixing claws of the two fixing brackets are arranged facing each other, and the bending curvature of the fixing claws matches that of the embryo.

[0018] In one possible implementation, a roller is also included;

[0019] The plurality of rollers are rotatably disposed on the first plate and the third plate, respectively;

[0020] The roller is vertically arranged, and its rotation direction is tangent to the surface of the first plate or the third plate.

[0021] In one possible implementation, the mounting bracket includes: a base, a support frame, and a fixing frame;

[0022] The base is slidably mounted on the guide rail;

[0023] The support frame has a preset length, is vertically mounted on the base, and the top of the support frame is located above the conveying bracket;

[0024] The fixed frame is fixedly connected to the top of the support frame and extends toward the conveying bracket, and the fixed clamp is disposed on the fixed frame.

[0025] In one possible implementation, the conveying support further includes: a support rod;

[0026] There are multiple support rods, and the multiple support rods are vertically arranged below the conveying bracket and located at the corner of the conveying bracket.

[0027] In one possible implementation, the first plate and the third plate are each provided with two or more of the rollers;

[0028] The installation positions and quantities of the rollers on the first plate body correspond one-to-one with the installation positions and quantities of the rollers on the third plate body.

[0029] One possible implementation also includes: a drive motor;

[0030] The drive motor is driven by the plurality of conveying guide rollers.

[0031] The beneficial effects of the positioning and fixing frame for tire carcass vulcanization in this application embodiment are as follows: Two fixing brackets are positioned at the ends of the conveyor support, i.e., the positions where the robot arm needs to grasp the tire carcass on the conveyor support. The opposing or back-to-back movement function of the fixing brackets can accurately clamp the tire carcass to the center position in the width direction of the conveyor support, ensuring accurate positioning of the tire carcass in the vulcanization molding device and reducing the defect rate caused by inaccurate positioning. Specifically, the two fixing brackets are positioned on both sides of the end of the conveyor support. After the tire carcass is conveyed to the end position by the conveyor guide rollers set at the top of the conveyor support, the two fixing brackets move towards each other, clamping the tire carcass at the center position in the width direction of the conveyor support. Then, the two fixing brackets move back to back, and the robot arm clamps the tire carcass onto the vulcanization molding machine to complete the vulcanization of the tire carcass.

[0042] like Figures 1-3 As shown, the positioning and fixing frame for tire carcass vulcanization in this embodiment includes: a conveying bracket 10 and a fixing bracket 20. The conveying bracket 10 is a hollow plate-like structure with multiple rotatable conveying guide rollers 11 along its length. The multiple conveying guide rollers 11 rotate in the same direction. There are two fixing brackets 20, which are located on both sides of the conveying bracket 10 along its length. The two fixing brackets 20 can move towards each other or away from each other and are suitable for clamping the tire carcass on the conveying bracket 10 to the center position in the width direction of the conveying bracket 10.

[0043] In this specific embodiment, two fixed supports 20 are positioned at the ends of the conveying support 10, i.e., at the positions where the robotic arm needs to grip the tire blank on the conveying support 10. The opposing or backward movement function of the fixed supports 20 can accurately clamp the tire blank to the center position in the width direction of the conveying support 10, ensuring accurate positioning of the tire blank in the vulcanization molding device and reducing the defect rate caused by inaccurate positioning. Specifically, the two fixed supports 20 are positioned on both sides of the end of the conveying support 10. After the tire blank is conveyed to the end position by the conveying guide roller 11 set at the top of the conveying support 10, the two fixed supports 20 move towards each other, clamping the tire blank at the center position in the width direction of the conveying support 10. Then, the two fixed supports 20 move backward, and the robotic arm clamps the tire blank onto the vulcanization molding machine to complete the vulcanization of the tire blank.

[0044] In one specific embodiment, the two fixed supports 20 are spaced equidistant from the conveying support 10, meaning the spacing between the two fixed supports 20 and the conveying support 10 remains constant. By simultaneously controlling the movement of the two fixed supports 20 towards or away from each other using a hydraulic cylinder 25, the tire blank can be clamped to the center position in the width direction of the conveying support 10 when the two fixed supports 20 move towards each other. Furthermore, the equidistant spacing between the two fixed supports 20 and the conveying support 10 ensures symmetrical and uniform clamping force, effectively preventing deformation of the tire blank due to uneven force during clamping.

[0045] In one specific embodiment, the movement direction of the two fixed supports 20 is perpendicular to the length direction of the conveying support 10, ensuring that the clamping and positioning operation of the tire blank is independent of and does not interfere with the conveying process of the tire blank. This ensures the continuity of tire blank conveying and achieves precise width direction positioning, thereby improving the working efficiency and reliability of the entire conveying fixed frame 221.

[0046] In one specific embodiment, the fixed bracket 20 includes: a guide rail 23, a mounting bracket 22, a hydraulic cylinder 25, and a fixing claw 21. The guide rail 23 is disposed below the conveying bracket 10, and the linear motion direction of the guide rail 23 is perpendicular to the conveying direction of the conveying bracket 10. The mounting bracket 22 is slidably disposed on the guide rail 23 and is vertically disposed, with its top located above the conveying bracket 10. Thus, the vertical height of the mounting bracket 22 can meet the clamping requirements of the tire blank on the conveying bracket 10. The hydraulic cylinder 25 is connected to the mounting bracket 22 and drives the mounting bracket 22 to reciprocate. The fixing claw 21 is disposed on the top of the mounting bracket 22 and moves towards each other with the two mounting brackets 22, clamping the tire blank at the center position in the width direction of the conveying bracket 10.

[0047] In this specific embodiment, a hydraulic cylinder 25 provides a stable driving force, and a guide rail 23 ensures the opposing or backward movement of the mounting brackets 22. A fixed gripper 21 ensures that the fixed bracket 20 can reliably clamp and position the tire blank. Specifically, when the two mounting brackets 22 move towards each other, the fixed gripper 21 clamps the tire blank, positioning it at the center of the width direction of the conveying bracket 10; when moving backward, it releases the tire blank.

[0048] In one specific embodiment, the fixing claw 21 is a plate-shaped structure with an arc, including a first plate 211, a second plate 212, and a third plate 213. The first plate 211, the second plate 212, and the third plate 213 are connected in sequence. The first plate 211 and the third plate 213 are located on the same side of the second plate 212. The angle between the first plate 211 and the second plate 212 is equal to the angle between the third plate 213 and the second plate 212. The fixing claws 21 of the two fixing brackets 20 are arranged facing each other, and the bending arc of the fixing claw 21 matches the tire blank.

[0049] Among them, the first plate 211 and the third plate 213 are hollow structures.

[0050] In this specific embodiment, the symmetrical arc structure of the fixed gripper 21 and the bending arc that matches the tire blank allow the gripper to better conform to the shape of the tire blank, increase the distribution area of ​​the clamping force, reduce the damage to the tire blank caused by excessive local pressure, and improve the stability of clamping, ensuring that the tire blank maintains an accurate position during transportation and positioning.

[0051] Specifically, the first plate 211 and the third plate 213 are located on the same side of the second plate 212, and the angles between the first plate 211 and the second plate 212, as well as the angles between the third plate 213 and the second plate 212, are equal, resulting in a symmetrical arc structure for the fixing claws 21. The fixing claws 21 of the two fixing brackets 20 are arranged facing each other, and the bending arc of the fixing claws 21 matches that of the tire blank, so that the displacement of the tire blank can be firmly controlled when the fixing claws 21 clamp and move the tire blank.

[0052] In one specific embodiment, it also includes rollers 24, and multiple rollers 24 are rotatably disposed on the first plate 211 and the third plate 213 respectively. The rollers 24 are vertically disposed and the rotation direction is tangent to the plate surface of the first plate 211 or the plate surface of the third plate 213.

[0053] In this specific embodiment, the roller 24 converts sliding friction into rolling friction, which significantly reduces the frictional resistance and wear on the tire blank surface during clamping, protects the surface quality of the tire blank, and makes the tire blank move more smoothly when it is clamped, improves the efficiency of conveying and positioning, and reduces the risk of tire blank damage due to excessive friction.

[0054] Specifically, when the fixed gripper 21 holds the tire blank, the roller 24 contacts the surface of the tire blank. During the movement of the tire blank, the roller 24 can rotate with the movement of the tire blank, thereby converting the sliding friction between the fixed gripper 21 and the tire blank into rolling friction, which greatly reduces the friction during the gripping process and allows the tire blank to move more smoothly.

[0055] In one specific embodiment, the mounting bracket 22 includes a base 223, a support frame 222, and a fixing frame 221. The base 223 is slidably mounted on the guide rail 23. The support frame 222 has a preset length and is vertically mounted on the base 223, with its top point positioned above the conveying bracket 10, providing vertical support for the fixing frame 221. This ensures that the fixing frame 221 can reach a suitable height to clamp the tire blank on the conveying bracket 10. The fixing frame 221 is fixedly connected to the top of the support frame 222 and extends towards the conveying bracket 10. A fixing claw 21 is mounted on the fixing frame 221. When the width of the conveying bracket 10 is too large, because the fixing frame 221 extends horizontally and the fixing claw 21 is positioned at one end of the extension of the fixing frame 221, even if the support frame 222 of the mounting bracket 22 does not need to slide to contact the conveying bracket 10, the fixing claws 21 of the two fixing brackets 20 can still clamp and position the tire blank.

[0056] In one specific embodiment, the conveying bracket 10 further includes: multiple support rods 12, which are vertically arranged below the conveying bracket 10 and located at the corners of the conveying bracket 10. The conveying bracket 10 is supported by the support rods 12, and a guide rail 23 for fixing the bracket 20 is then provided below the conveying bracket 10.

[0057] In one specific embodiment, the first plate 211 and the third plate 213 are respectively provided with two or more rollers 24. The installation position and number of rollers 24 on the first plate 211 correspond one-to-one with the installation position and number of rollers 24 on the third plate 213, ensuring that the two sides of the tire blank are subjected to uniform rolling friction force, so that the tire blank maintains a stable posture during the clamping and moving process.

[0058] In one specific embodiment, it further includes a drive motor 13, which is connected to a plurality of conveying guide rollers 11 to provide power for the rotation of the conveying guide rollers 11.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
