Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this space-saving automatic alignment device includes: a main frame 1, a drive module 2, an outer baffle module, and an inner baffle module. The main frame 1, serving as the foundational support structure of the entire device, is made of alloy material, possessing excellent rigidity and stability, capable of bearing various loads during device operation, and providing a solid guarantee for the precise coordination of other components. There are two drive modules 2, each controlled to drive the outer baffle module and the inner baffle module to perform bisecting movements relative to the main frame 1. The outer baffle module consists of two mutually symmetrical outer positioning baffles 301, and the inner baffle module consists of two mutually symmetrical inner positioning baffles 302, with the two inner positioning baffles 302 located between the two outer positioning baffles 301. The main frame 1, the outer positioning baffles 301, and the inner positioning baffles 302 are all arranged in a fan shape and are concentrically positioned. Several through slots 8 are provided on the outer positioning baffle 301 and the inner positioning baffle 302. Several idler rollers 6 are installed on the main frame 1. The idler rollers 6 are made of a composite structure with high-quality rubber wrapped around a steel shaft, which ensures a certain amount of friction to support the movement of objects, while reducing noise and preventing damage to the supported objects. The idler rollers 6 pass through the through slots 8 respectively, and the idler rollers 6 can rotate along their own axes without interfering with the outer positioning baffle 301 and the inner positioning baffle 302. Several vertical stop wheels 7 are rotatably installed on the outer positioning baffle 301 and the inner positioning baffle 302 respectively. The vertical stop wheels 7 are made of high-hardness polyurethane material. The outer polyurethane coating has wear resistance and cushioning performance, while the inner hub is made of aluminum alloy to ensure structural stability. The vertical stop wheels 7 can rotate along their own axes. The axis of the upright stop wheel 7 is set along the radius of the circle containing the outer positioning baffle 301 and the inner positioning baffle 302. When the object comes into contact with the upright stop wheel 7, the upright stop wheel 7 can not only play a precise lateral limiting role, but also reduce the frictional resistance between the object and the baffle through its own rotation.

[0032] like Figure 4As shown, the drive module 2 includes: a frame 21, a linear guide rail 22, a stepper motor 23, a coupling 24, a bearing housing 25, a lead screw 26, and a connecting block 27. The frame 21, serving as the basic support structure of the drive module 2, is made of aluminum alloy. This material has advantages such as light weight, high strength, and corrosion resistance, which can reduce the weight of the entire device while ensuring structural stability. The frame 21 is securely mounted on the main frame 1 using multiple bolts. The linear guide rail 22 is installed inside the frame 21. The linear guide rail 22 is made of aluminum alloy with a U-shaped cross-section and a smooth inner wall. The stepper motor 23 is mounted on the frame 21. The stepper motor 22 is an existing device; in this embodiment, the NEMA 17 model is selected. This model of stepper motor 23 communicates with an external PLC via RS-485 communication, thereby controlling the stepper motor 23 according to the PLC settings. Coupling 24 is installed at the output end of stepper motor 23. Coupling 24 is a flexible coupling, a common type of equipment, which effectively compensates for coaxiality errors and angular deviations between the output shaft of stepper motor 23 and lead screw 26, reducing vibration and impact during transmission and improving transmission stability and reliability. Bearing housing 25 is installed on frame 21, providing support and positioning for lead screw 26. One end of lead screw 26 is rotatably mounted on frame 21, and the other end passes through bearing housing 25 and connects to coupling 24. The threads on the left and right sides of the outer wall of lead screw 26 are symmetrically arranged. There are two connecting blocks 27, each symmetrically threaded onto lead screw 26. When lead screw 26 rotates, it drives the two connecting blocks 27 to move relative to or in opposite directions, thereby achieving the bisecting movement of the outer and inner baffle modules. The bottom of the connecting block 27 is slidably installed in the linear guide rail 22 to ensure that when the lead screw 26 rotates, the connecting block 27 can move precisely along the axial direction of the lead screw 26, thus preventing the connecting block 27 from rotating on its own.

[0033] The specific steps of the above structure in actual use are as follows: When the control system issues a command, the stepper motor 23 starts to rotate, transmitting power to the lead screw 26 through the coupling 24. Driven by the stepper motor 23, the lead screw 26 begins to rotate. Because the threads on the left and right sides of the lead screw 26's outer wall are symmetrical, the two connecting blocks 27 will move relative to or in opposite directions along the linear guide 22. The connecting blocks 27 are connected to the outer baffle module or the inner baffle module, thereby driving the two outer positioning baffles 301 or the two inner positioning baffles 302 to move relative to or in opposite directions. This achieves the automatic centering function for the object. Throughout the entire driving process, all components work closely together to ensure the accuracy and stability of the movement.

[0034] In actual use, the tire carcass, steel wire cloth, rubber pad, and belt layer are placed on the main frame 1 in sequence and supported by the roller 6. Then, the two inner positioning baffles 302 move away from each other to achieve internal support for the tire carcass, steel wire cloth, rubber pad, and belt layer, while ensuring automatic centering. Then, the two outer positioning baffles 301 move closer to each other to achieve external limiting, while the vertical stop wheel 7 is used for limiting.

[0035] In addition, such as Figure 2 As shown, a switch bracket 4 is mounted on the main frame 1, and a switch 5 is mounted on the switch bracket 4 via a sliding connection. This sliding connection design allows the switch 5 to move flexibly on the switch bracket 4. The switch 5 is a photoelectric proximity switch, specifically the E2E series model, which is an existing device. Its working principle utilizes the reflection characteristics of light to detect the approach of an object. When the inner positioning baffle 302 approaches the switch 5, the light emitted by the switch 5 is reflected back by the inner positioning baffle 302 and received by the receiver of the switch 5. This method determines the position of one of the inner positioning baffles 302, ensuring that the position of the inner positioning baffle 302 can accurately find the initial 0-point position. The switch 5 is slidably connected to the switch bracket 4, and a set screw is threaded onto the switch 5. The end of the set screw tightly abuts against the surface of the switch bracket 4, thus fixing the switch 5 and the switch bracket 4 together and ensuring that the switch 5 will not shift during operation. In actual use, the 0-point position needs to be adjusted according to different working requirements and specifications. The operator manually moves the switch 5 to slide it on the switch bracket 4. During the sliding process, the position of switch 5 changes, thereby altering the position of its sensing inner positioning baffle 302. Once adjusted to the appropriate position, the operator rotates the set screw on switch 5 to secure it to the switch bracket 4. Subsequently, the operator adjusts the position of the inner positioning baffle 302, gradually bringing it closer to switch 5. By observing the sensing status of switch 5, the operator determines whether the inner positioning baffle 302 has reached the preset position. If the inner positioning baffle 302 has reached the appropriate position, the light emitted by switch 5 will be reflected back by the inner positioning baffle 302, and the indicator light on switch 5 will change, indicating that the inner positioning baffle 302 has reached its position. At this point, the adjustment and confirmation of the 0 point position is complete.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
