[0042] The embodiments of this utility model will be described in detail below.

[0043] This utility model discloses a novel vehicle recirculation device. The first slide rail 1 and the second slide rail 2, which are inclined, form an angle of not less than 5° with the horizontal plane. This structure allows the vehicle 5 to automatically slide along the first slide rail 1 and the second slide rail 2 under the action of gravity, reducing reliance on the active drive device and helping to reduce the energy consumption and operating costs of the equipment. An electric push rod 4 is provided at the connection between the first slide rail 1 and the second slide rail 2. This structure provides necessary auxiliary thrust when the vehicle 5 moves to the connection point of the first slide rail 1 and the second slide rail 2, thereby helping the vehicle 5 smoothly transition from the first slide rail 1 to the second slide rail 2 and ensuring the continuity of the vehicle 5 recirculation process. The specific details of this embodiment are as follows:

[0044] Figure 1 This is a schematic diagram of a novel carrier return device according to the present invention; Figure 2 This is a front view of a schematic diagram of the structure of a new type of vehicle return equipment; Figure 3 Right view of the structural schematic diagram of the new type of vehicle return equipment; Figure 4 This is a top view of the structural schematic diagram of the novel vehicle return equipment. In this embodiment, the first slide rail 1 is made of aluminum alloy profile through an extrusion molding process, and its surface is anodized to improve wear resistance. The function of this component is to provide a conveying channel with a specific inclination angle. The first slide rail 1 extends along a first direction, and its angle α1 with the horizontal plane is set to 10°; this inclination angle allows the vehicle 5 placed on it to generate a tendency to move along the first direction under the action of the component of gravity. In other embodiments, the angle α1 can also be adjusted to an inclination angle of not less than 5°, such as 8°, 12°, or 15°, according to the actual load weight and friction coefficient, to meet the speed requirements under different working conditions. The length of the first slide rail 1 can be designed to be 2-5 meters according to the site layout requirements, preferably 3 meters.

[0045] The second slide rail 2 is also made of aluminum alloy profile, and its surface is galvanized to improve corrosion resistance. Its function is to receive the carrier 5 from the first slide rail 1 and continue to transport it. The second slide rail 2 extends along the second direction, and its angle α2 with the horizontal plane is also set to 10°. Its upstream end is fixed to the downstream end of the first slide rail 1 by bolt connection, and the connection adopts an arc transition design to reduce the impact when the carrier 5 passes. In this embodiment, the angle between the first direction and the second direction is 90°, which helps to save equipment layout space; in other embodiments, this angle can also be adjusted to 60° or 80°, or an angle not greater than 90°, according to the site layout requirements.

[0046] Figure 5 This is a schematic diagram of the roller structure of a new type of vehicle return equipment; Figure 6 This is a right-hand view of the roller structure of the novel carrier return device. Rollers 3 are installed on both the first slide rail 1 and the second slide rail 2. The rollers 3 are rotatably mounted on the slide rails via bearing assemblies, with an installation spacing of 150-300mm, preferably 200mm. The function of the rollers 3 is to support the carrier 5 and convert its sliding friction into rolling friction, thereby reducing motion resistance. In this embodiment, the rollers 3 are made of polyurethane material through a casting molding process. This material is chosen to provide suitable elasticity while ensuring load-bearing capacity. The rollers 3 are frustum-shaped, with a large end diameter of 80mm, a small end diameter of 20mm, and a height of 30mm. This frustum-shaped structure creates an inclined mating surface between the side of the roller 3 and the contact surface of the carrier 5. When the carrier 5 presses against the roller 3 under gravity, a guiding force pointing towards the center of the track is generated. This force can automatically correct any lateral deviation that may occur during the movement of the carrier 5, helping to maintain its movement along a predetermined path.

[0047] Regarding the geometric parameters of roller 3, in this embodiment, the semi-conical angle formed by the generatrix of its side and the axis of rotation is specifically set to 45°. This angle design ensures stable contact between the carrier 5 and roller 3 while providing sufficient guiding force, avoiding the risk of slippage due to excessive angle. In other embodiments, this semi-conical angle can also be selected as a value not exceeding 60°, such as 30° or 50°, depending on the bottom structure and weight distribution of the carrier 5, to balance the guiding effect and operational stability.

[0048] Figure 7This is a schematic diagram of the electric push rod structure of the novel carrier return device. An electric push rod 4 is installed at the connection between the first slide rail 1 and the second slide rail 2. Its rated thrust is 50N, stroke is 200mm, and push rod speed is adjustable from 10-100mm / s. The function of the electric push rod 4 is to provide necessary auxiliary thrust to the carrier 5 as it moves along the first direction to the downstream end of the first track 1, overcoming the resistance at the track connection point and ensuring that the carrier 5 can smoothly transition to the upstream beginning of the second slide rail 2 and continue sliding along the second direction. A pad 41 is provided at the end of the working shaft of the electric push rod 4. This pad 41 is made of engineering plastic and fixed to the push rod shaft end with screws. The function of the pad 41 is to increase the contact area with the carrier 5, making the thrust distribution more uniform, thereby reducing local impact and wear on the carrier 5. In other embodiments, pads 41 of different sizes or shapes can be used depending on the size and weight of the carrier 5, such as rectangular or circular pads, and the material can also be elastic materials such as rubber or polyurethane.

[0049] This utility model adopts a structure combining an inclined first slide rail 1 and a second slide rail 2, using gravity as the main driving force; it adopts a structure of frustum-shaped rollers 3 to realize the self-guiding function during the movement of the carrier 5; and it adopts a structure combining an electric push rod 4 and a pad 41 to solve the turning problem at the track connection.

[0050] Overall, this solution, through the synergistic effect of gravity utilization, mechanical guidance, and local power assistance, simplifies the equipment structure, reduces system energy consumption and operating costs, and helps improve the automation level and operational reliability of the carrier return process, thus having a certain positive effect on material handling in electronic product production lines.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
