Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, specifically to a carrier return mechanism for a production line. Background Technology

[0002] In modern industrial production, automated production lines are increasingly widely used, and their efficiency and precision are crucial for improving product quality and reducing production costs. The carrier return mechanism on the production line, as a key device connecting the front and back ends of production, is responsible for efficiently and accurately returning the carriers to their starting positions after processing or assembly tasks, thus enabling continuous cyclical operation. The smoothness of this process directly affects the overall efficiency and stability of the production line.

[0003] Currently, in practical applications of automated production lines, due to the wide variety of products, production lines need to frequently change different models of carriers to adapt to diverse product processing needs. However, most existing carrier return mechanisms adopt a fixed double-rail design. The distance between these tracks is not adjustable, which means that when handling carriers of different widths, the entire return mechanism must be redesigned or modified. This is not only time-consuming and labor-intensive but also increases the company's operating costs. At the same time, this fixed design limits the flexibility of the production line and reduces production efficiency, especially when facing small-batch, multi-variety production modes, where adjustments to the production line become more complex and reduce production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a carrier return mechanism for a production line, so as to solve the problems of poor adaptability and insufficient flexibility of the fixed double-track design of the carrier return mechanism of the current automated production line mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carrier return mechanism for a production line, comprising a base plate, guide rail supports on both sides of the top of the base plate, a guide rail body mounted on the top of the guide rail supports, horizontally distributed guide posts in the middle of the top of the base plate, guide sleeves fitted on both ends of the guide posts, the top of the guide sleeves mounted in the middle of the bottom of the guide rail supports, and symmetrical adjustment seats below the guide posts, an adjustment mechanism on the adjustment seats, and the adjustment mechanism connected to the guide sleeves via a linkage.

[0006] Preferably, the adjusting mechanism includes a screw ring, a lead screw, and a motor. The lead screw is disposed in a strip-shaped groove on the adjusting seat. The screw ring is sleeved on the outside of the lead screw through a threaded structure, and the outer side of the screw ring is fixedly connected to the bottom end of the linkage. The motor is fixedly installed on one side outside the adjusting seat.

[0007] Preferably, the bottom of the guide sleeve is equipped with a guide wheel via a support block, and the top of the adjusting seat is provided with a guide groove that matches the structure of the guide wheel.

[0008] Preferably, the base plate can be detachably installed with support plates at both the front and rear ends, and the guide rail bracket is provided with sliders at both the front and rear ends, and the inner side of the support plate is provided with a sliding groove that cooperates with the slider.

[0009] Preferably, the top of the guide sleeve is provided with an insert, and the bottom of the guide rail bracket is provided with a groove that matches the structure of the insert.

[0010] Preferably, the linkage component has an arc-shaped structure, and the linkage component is fixedly connected to one side edge of the guide sleeve.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The carrier return mechanism of this production line, through the design of an adjustable-spacing double-guide rail structure, achieves efficient and flexible handling of carriers of different specifications, thereby improving the overall efficiency of the production line and reducing costs. The carrier return mechanism of this production line, through the design of the adjustment mechanism, guide sleeve, and guide column, realizes rapid adjustment of the guide rail body spacing. At the same time, the adjustment seat enhances the stability of the overall structure, ensuring the accuracy and smoothness of the adjustment process, further improving the adaptability and flexibility of the production line.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a carrier return mechanism for a production line, including a base plate 1 with mounting holes at all four corners for installation at appropriate positions on the production line. Guide rail brackets 2 are provided on both sides of the top of the base plate 1, and a guide rail body 3 is fixedly mounted on the top of each guide rail bracket 2. A sliding block is driven onto the guide rail body 3. Horizontally distributed guide posts 4 are provided in the middle of the top of the base plate 1, with both ends of the guide posts 4 welded and fixed to the two sides of the middle of the top of the base plate 1 via support blocks. Guide sleeves 5 are movably fitted onto the outer sides of both ends of the guide posts 4. The bottom of the guide rail brackets 2 is mounted on the top of the guide sleeves 5, and symmetrical adjustment seats 6 are provided below the guide posts 4. The bottom of the adjustment seats 6 is welded and fixed to the top of the base plate 1, and an adjustment mechanism 9 is provided on the adjustment seats 6. 9 is connected to the guide sleeve 5 via the linkage 8. When the distance between the guide rail bodies 3 needs to be adjusted to accommodate carriers of different widths, the operator can adjust it via the adjustment mechanism 9. The action of the adjustment mechanism 9 is transmitted to the guide sleeve 5 through the linkage 8, causing the guide sleeve 5 to slide along the guide post 4, thereby moving the guide rail bracket 2 mounted on top of the guide sleeve 5 and the guide rail bodies 3 on it, achieving precise adjustment of the distance between the guide rail bodies 3. Simultaneously, the adjustment seat 6 provides a stable foundation for the adjustment mechanism 9, ensuring stability and reliability during the adjustment process. Ultimately, in this way, the carrier return mechanism can be quickly and accurately adjusted to the working state suitable for a specific carrier without redesigning or modifying the entire return mechanism, significantly improving the production line efficiency. This design offers excellent adaptability and production efficiency for different vehicle specifications, making it particularly suitable for small-batch, multi-variety production. It effectively solves the problems of poor adaptability and insufficient flexibility in existing fixed double-track designs. The adjustment mechanism 9 includes a screw ring 91, a lead screw 92, and a motor 93. The lead screw 92 is located in a groove on the adjustment seat 6, with both ends connected to the sides of the groove via bearings. The screw ring 91 is threaded onto the outside of the lead screw 92, and its outer side is fixedly connected to the bottom of the linkage 8. The motor 93 is fixedly installed on one side of the outside of the adjustment seat 6, with its output end penetrating into the groove and fixedly connected to one end of the lead screw 92. This structure allows the motor 93 to drive the lead screw upon startup. The lead screw 92 rotates within the groove on the adjusting seat 6. As the lead screw 92 rotates, it drives the screw ring 91 to move axially along the outer side of the lead screw 92. Simultaneously, the linkage 8 moves horizontally left and right, thereby causing the guide sleeve 5 to slide horizontally along the guide post 4. This ultimately adjusts the distance between the two sets of guide rail supports 2 and the guide rail body 3. The bottom of the guide sleeve 5 is equipped with a guide wheel 7 via a support block, and the top of the adjusting seat 6 has a guide groove that matches the structure of the guide wheel 7. When the guide sleeve 5 slides horizontally along the guide post 4, the guide wheel 7 can roll within the guide groove on the top of the adjusting seat 6. This tight fit between the guide wheel 7 and the guide groove reduces the frictional resistance during the movement of the guide sleeve 5, ensuring smooth and stable movement. Simultaneously, the rolling of the guide wheel 7 within the guide groove also provides guidance.This design prevents the guide sleeve 5 from shifting or jamming during movement, ensuring the accuracy of the spacing adjustment between the guide rail bracket 2 and the guide rail body 3. Support plates 10 are detachably mounted on both the front and rear ends of the base plate 1 via bolts. Slider blocks 11 are provided on both the front and rear ends of the guide rail bracket 2, and the inner side of the support plate 10 has a groove that mates with the slider 11. When the guide rail bracket 2 moves horizontally along the guide post 4 with the guide sleeve 5, the slider 11 slides in the groove on the inner side of the support plate 10. The interaction between the slider 11 and the groove not only restricts the direction of movement of the guide rail bracket 2, ensuring the straightness of its horizontal movement, but also increases the stability of the structure, preventing the guide rail bracket 2 from shifting. The movement process generates swaying or offset, further ensuring the accuracy and reliability of the guide rail body 3 spacing adjustment. An insert 12 is welded and fixed to the top of the guide sleeve 5, and a groove matching the structure of the insert 12 is provided in the middle of the bottom of the guide rail bracket 2. This structure allows the guide rail bracket 2 to be inserted into the outside of the insert 12 through the groove, ensuring a stable connection between the guide rail bracket 2 and the guide sleeve 5. This tight fit enhances the stability of the guide rail bracket 2 during movement. The linkage 8 has an arc-shaped structure and is fixedly connected to one edge of the guide sleeve 5. This structure of the linkage 8 reduces interference with other components during movement, ensuring smooth movement.

[0019] Working principle: When using the carrier return mechanism of this production line, the base plate 1 is first fixed to the designated position of the production line through the mounting holes at the four corners. Then, when it is necessary to adjust the distance between the two guide rail bodies 3 to accommodate carriers of different widths, the motor 93 of the adjustment mechanism 9 is started. The output end of the motor 93 rotates and drives the lead screw 92 to rotate in the strip groove opened on the adjustment seat 6. When the lead screw 92 rotates, it drives the screw ring 91 to move along the axial direction of the lead screw 92. The movement of the screw ring 91 causes the linkage 8 to move left and right in the horizontal direction. The movement of the linkage 8 then drives the guide sleeve 5 to slide horizontally along the guide post 4. When the guide sleeve 5 moves, the guide wheel 7 at its bottom rolls in the guide groove at the top of the adjustment seat 6. At the same time, the movement of the guide rail bracket 2 is achieved by the sliders 11 at its front and rear ends sliding in the grooves on the inner side of the support plate 10, ensuring the straightness of the horizontal movement of the guide rail bracket 2. Finally, the precise adjustment of the distance between the two guide rail bodies 3 is achieved, thus completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
