One end of the first screw 25 is installed with a first motor 24 for driving the first screw 25 to rotate. The first motor 24 is installed inside the first adjusting frame 2. The end of the first screw 25 away from the first motor 24 is rotatably connected to the inner wall of the first adjusting frame 2. A first sliding groove 3 parallel to the first screw 25 is opened on the side wall of the first adjusting frame 2 close to the first mounting frame 6. The side wall of the first screw 25 is connected to the first screw 25 by the screw.

[0028] When in use, the first motor 24 is started, and the output end of the first motor 24 drives the first screw 25 to rotate. Under the action of the thread, the first screw 25 drives the first moving block 26 to move, and the first moving block 26 drives the first installation frame 6 to move. The first installation frame 6 drives the first displacement sensor 5 to move. The first displacement sensor 5 measures the distance moved by the first installation frame 6 in real time and transmits the measured data to the controller 22.

[0029] The second moving mechanism includes a second screw 28, which is arranged inside the second adjusting frame 18. The second screw 28 is parallel to the positioning plate 16. One end of the second screw 28 is installed with a second motor 27 for driving the second screw 28 to rotate. The second motor 27 is installed inside the second adjusting frame 18. The end of the second screw 28 away from the second motor 27 is rotatably connected to the inner wall of the second adjusting frame 18. A second sliding groove 19 parallel to the second screw 28 is opened on the side wall of the second adjusting frame 18 close to the second mounting frame 20. The side wall of the second screw 28 is rotatably connected to the second screw 28 through a thread. A second moving block 29 is connected, and one end of the second moving block 29 close to the second mounting frame 20 is installed on the second mounting frame 20 through the second slide groove 19. A ball bearing is installed on the inner wall of the second mounting frame 20 to facilitate the movement of the second mounting frame 20 along the side wall of the second adjustment frame 18. A second displacement sensor 21 for measuring the moving distance of the second mounting frame 20 is installed on the side wall of the second mounting frame 20. A second measuring baffle 4 for use with the second displacement sensor 21 is installed on one end of the side wall of the second adjustment frame 18 close to the second displacement sensor 21, and the detection end of the second displacement sensor 21 is facing the second measuring baffle 4.

[0030] When in use, the second motor 27 is started, and the output end of the second motor 27 drives the second screw 28 to rotate. Under the action of the thread, the second screw 28 drives the second moving block 29 to move, and the second moving block 29 drives the second installation frame 20 to move. The second installation frame 20 drives the second displacement sensor 21 to move. The second displacement sensor 21 measures the distance moved by the second installation frame 20 in real time and transmits the measured data to the controller 22.

[0031] The detection mechanism includes an L-shaped mounting frame 9. A groove 10 is formed at one end of the positioning plate 16 away from the connecting rod 17. The L-shaped mounting frame 9 is installed at the lower end of the side wall of the positioning plate 16 close to the second adjustment frame 18. The L-shaped mounting frame 9 and the connecting rod 17 are parallel to each other. A laser rangefinder 7 for detecting whether the tire half component 23 is in close contact with the positioning plate 16 is installed on the side wall of the L-shaped mounting frame 9 opposite to the groove 10.

[0032] During use, the measuring light emitted by the laser rangefinder 7 passes through the groove 10 and shines on the sidewall of the tire half component 23 to obtain a distance value. The laser rangefinder 7 then transmits the measured distance value to the controller 22. Since the distance between the laser rangefinder 7 and the positioning plate 16 is a fixed value, the controller 22 compares the measured distance value with the fixed value between the laser rangefinder 7 and the positioning plate 16. If the difference is large and exceeds the qualified range, it is determined that the tire half component 23 is not in close contact with the sidewall of the positioning plate 16. At this time, the controller 22 alarms and provides a prompt for the staff to adjust the position of the tire half component 23.

[0033] The auxiliary adjustment mechanism includes a limiting telescopic rod 11, which is installed on a positioning plate 16 between the L-shaped mounting frame 9 and the connecting rod 17. The limiting telescopic rod 11 and the connecting rod 17 are parallel to each other. The sliding rod at the output end of the limiting telescopic rod 11 is not restricted and can slide freely on the inner wall of the fixed tube of the limiting telescopic rod 11. A mounting block 13 is installed on the sliding rod at the output end of the limiting telescopic rod 11, and an elastic telescopic rod 14 is installed on the mounting block 13. The elastic telescopic rod 14 is parallel to the positioning plate 16, and the output end of the elastic telescopic rod 14 faces the side away from the first adjustment frame 2. The output end of the elastic telescopic rod 14 is installed with an L-shaped mounting rod 15, and the end of the L-shaped mounting rod 15 away from the elastic telescopic rod 14 is installed with a friction block 12.

[0034] During use, the staff moves the L-shaped mounting rod 15 toward the tire half component 23. The L-shaped mounting rod 15 compresses the elastic telescopic rod 14 and drives the friction block 12 to press tightly against the tire half component 23. Then, the L-shaped mounting rod 15 is moved along the straight line direction where the connecting rod 17 is located. The L-shaped mounting rod 15 drives the friction block 12 to move. The friction block 12 adjusts the position of the tire half component 23. At the same time, the L-shaped mounting rod 15 drives the elastic telescopic rod 14 and the mounting block 13 to move. The mounting block 13 drives the sliding rod at the output end of the limiting telescopic rod 11 to move.

[0035] Working principle of a tire building machine auxiliary drum half component positioning device:

[0036] When the tire half component 23 is to be attached to the auxiliary drum 30 of the tire building machine, the size of the tire half component 23 is input into the controller 22, and the controller 22 calculates the lateral movement distance of the positioning plate 16. Specifically:

[0037] Start the first motor 24, and the output end of the first motor 24 drives the first screw 25 to rotate. Under the action of the thread, the first screw 25 drives the first moving block 26 to move, and the first moving block 26 drives the first mounting frame 6 to move, and the first mounting frame 6 drives the second adjusting frame 18 to move, and the second adjusting frame 18 drives the second mounting frame 20 to move, and the second mounting frame 20 drives the connecting rod 17 to move, and the connecting rod 17 drives the positioning plate 16 to move. At the same time, the first mounting frame 6 drives the first displacement sensor 5 to move, and the first displacement sensor 5 measures the distance moved by the first mounting frame 6 in real time, and transmits the measured data to the controller 22 to ensure the accuracy of the lateral movement of the positioning plate 16.

[0038] Then start the second motor 27, and the output end of the second motor 27 drives the second screw 28 to rotate. Under the action of the thread, the second screw 28 drives the second moving block 29 to move, and the second moving block 29 drives the second mounting frame 20 to move. The second mounting frame 20 drives the connecting rod 17 to move, and the connecting rod 17 drives the positioning plate 16 to move, so that the lower end of the positioning plate 16 is flush with the surface of the auxiliary drum 30 of the tire building machine. At the same time, the second mounting frame 20 drives the second displacement sensor 21 to move. The second displacement sensor 21 measures the distance moved by the second mounting frame 20 in real time and transmits the measured data to the controller 22 to ensure the accuracy of the movement of the lower end of the positioning plate 16.

[0039] Then, the first layer of tire half component 23 is fitted on the auxiliary drum 30 of the tire building machine, and the sidewall of the tire half component 23 is made to cling to the sidewall of the positioning plate 16 to achieve auxiliary positioning of the tire half component 23. At the same time, the measuring light emitted by the laser rangefinder 7 passes through the groove 10 and irradiates the sidewall of the tire half component 23 to obtain a distance value. The laser rangefinder 7 then transmits the measured distance value to the controller 22. Since the distance between the laser rangefinder 7 and the positioning plate 16 is a fixed value, the controller 22 compares the measured distance value with the fixed value between the laser rangefinder 7 and the positioning plate 16. If the difference is large and exceeds the qualified range, it is determined that the tire half component 23 is not clinging to the sidewall of the positioning plate 16. At this time, the controller 22 alarms and provides the staff with a way to adjust the position of the tire half component 23.

[0040] When the second layer of tire half components 23 is being bonded, the controller 22 adjusts the position of the positioning plate 16 again so that the lower end of the positioning plate 16 is away from the auxiliary drum 30 of the tire building machine by the thickness of the first layer of tire half components 23. Then, the second bonding operation of the tire half components 23 is completed, and finally, the bonding operation of the multiple layers of tire half components 23 is completed.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
