AI Technical Summary
In the prior art, when the robot arm of the vulcanizing machine transfers the tire blank to the center of the vulcanizing machine, it is prone to eccentricity, which leads to inaccurate positioning of the tire blank bead and the steel rim under the mold, resulting in problems such as large sidewalls, exposed steel wires at the bead, or tire deformation in the finished tire.
A robotic centering device for a vulcanizing machine is adopted. By installing a turntable and a centering plate on the center of the vulcanizing machine, a laser rangefinder probe is used to measure the offset error in real time and transmit the error value to the control program of the robotic arm to achieve automated adjustment and ensure accurate centering of the tire blank above the vulcanizing machine.
It achieves automatic centering of the tire blank above the vulcanizing machine, avoiding quality problems of finished tires, improving work efficiency, reducing the number of repeated adjustments by personnel, and improving production accuracy and efficiency.

[0025] Embodiment:
[0026] Please refer to Figs. 1-3 A mechanical hand centering equipment of curing machine, including curing machine center machine 1, the upper end of the curing machine center machine 1 is fixedly connected with base 2, the inner wall between base 2 is installed with turntable 3, the upper end of base 2 is fixedly connected with limiting frame 4, four centering plates 5 are movably connected between limiting frame 4 and turntable 3, four centering plates 5 are distributed in cross shape, and the outer end is embedded and installed with laser ranging probe 6.
[0027] In use, when the robot transfers the tire blank to the center machine 1, the personnel drives the rotating disc 3 to rotate, which causes the four centering plates 5 to expand outward between the inner walls of the limiting frame 4. Since the four centering plates 5 are in a synchronous displacement, the outer diameters of the four centering plates 5 remain on the same center. When the tire blank is placed off-center, the tire blank is automatically centered by the contact of the centering plates 5. The sub-port of the tire blank and the falling position of the lower steel ring of the mold are in the same concentricity, which avoids the phenomenon of large edge, sub-port wire leakage or tire deformation caused by the deviation of the falling position of the sub-port of the tire blank and the lower steel ring of the mold.
[0028] When the centering plates 5 contact the tire blank to automatically center, the laser ranging probe 6 synchronously generates a ray. When one side of the laser ranging probe 6 contacts one side of the tire blank, the error value is 0. The other side has a certain distance between the laser ranging probe 6 and the surface, and the distance is the error value. The subsequent error value generated by the laser ranging probe 6 is transmitted to the program of the synchronous control of the robot, which timely and automatically adjusts the position of the subsequent tire falling of the robot, avoids the repeated loading of the tire blank by personnel, improves the work efficiency, and avoids the robot still transferring the tire blank to the pre-offset position when transferring the tire blank for the second time.
[0029] Please refer to Figs. 1-3 The upper end of the base 2 is provided with a groove 21, and the inner bottom end of the base 2 is provided with a motor 22. The rotating disc 3 is located between the inner walls of the groove 21, and the bottom is fixedly connected with the output end of the motor 22.
[0030] More specifically, the upper end of the rotating disc 3 is provided with four evenly distributed arc-shaped grooves 31, the center end of the arc-shaped groove 31 is fixedly connected with a bearing seat 32, the lower end of the centering plate 5 is fixedly connected with a limiting shaft 51, the limiting shaft 51 is located between the inner walls of the arc-shaped groove 31, and the bottom end of the limiting shaft 51 is fixedly connected with a limiting ring 52, and the limiting ring 52 is located on the bottom side of the rotating disc 3.
[0031] More specifically, the limiting frame 4 is provided with a limiting groove 41 on each of the two adjacent right-angle end side walls, and the centering plate 5 is located between the inner walls of the limiting groove 41.
[0032] In the use process of the scheme, when the embryo needs to be centered, personnel drives the motor 22 to drive the rotating disc 3 to rotate, and because the centering plate 5 is limited by the linear distance of the limiting groove 41, when the rotating disc 3 rotates counterclockwise, the limiting shaft 51 drives the centering plate 5 to make linear displacement outward under the guidance of the arc-shaped groove 31, thereby, the four centering plates 5 move to the inside of the embryo under the concentric and synchronous displacement, the offset embryo is restored to the correct position, and the laser ranging probe 6 records the error value of the offset embryo and transmits it to the control program of the manipulator, so that the next time the embryo is transferred, the grabbing position program of the manipulator is adjusted synchronously, and the phenomenon that the manipulator continuously transfers the embryo at the position until the personnel finds the problem and adjusts is avoided.
[0033] Please refer to Figs. 1-3 The upper end of the limiting frame 4 is fixedly connected with a cover plate 7.
[0034] In the use process of the scheme, the cover plate 7 is installed at the upper end of the limiting frame 4, so that dust is not easily accumulated in the limiting frame 4.
[0035] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any person skilled in the art, according to the technical scheme and improvement concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
