[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. 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 protection scope of this utility model.

[0023] See Figure 1 , Figure 3 An AGV chain attachment device includes a transfer vehicle body 7 (not shown) and a chain 6 (not shown) connected to the transfer vehicle body 7. The transfer vehicle body 7 is provided with a chain support platform. The chain support platform is configured with a positioning end face that is raised and adapted to the hook 5 of the chain 6. The end of the positioning end face facing the hook 5 is provided with a positioning groove 21 adapted to the hook 5. The positioning groove 21 is provided with a sensor switch 31 (not shown) for detecting the hook 5. The positioning groove 21 can position the hook 5 to ensure that the hook 5 can enter the detection end of the sensor switch 31. The sensor switch 31 can detect whether the hook 5 is hooked into the positioning groove 21. If detected, it indicates that the hook 5 has been removed from the vehicle body, thereby ensuring the safe use of the AGV transfer vehicle after the rear axle is assembled.

[0024] It should be noted that the induction switch 31 is existing technology, and this embodiment does not involve any improvement to the induction switch 31. Its specific structure will not be described in detail. In this embodiment, the transfer vehicle body 7 is the body of the AGV transfer trolley. The body is the body to be assembled, which can be the body of the rear axle to be assembled. The transfer vehicle body 7 is equipped with a lifting mechanism, which can lift the rear axle. When assembling the rear axle, the hook 5 at the end of the chain 6 hooks onto the rear anti-collision beam of the body, which facilitates the assembly of the rear axle.

[0025] By connecting the induction switch 31 to the controller, the controller controls the power supply to or off of the transfer vehicle 7, which can prevent personnel from driving the AGV transfer vehicle away from the rear axle installation area (i.e., the assembly area) before the hook 5 is removed from the vehicle body, thus preventing damage to the vehicle body and the AGV transfer vehicle. The vehicle body 7 and the rear axle are transported to the assembly area by different carriers. In this embodiment, the rear axle is transported by the transfer vehicle 7, and the vehicle body 7 is transported by the conveyor line of the assembly line. The conveyor line is existing technology. When the induction switch 31 controls the transfer vehicle 7 to be powered on, the AGV transfer vehicle can accelerate away from the assembly area, improving the turnover efficiency.

[0026] See Figure 1The hanging chain support platform includes a fixed base plate 1, a first connecting block 11, a second connecting block 12, and a third connecting block 13. The fixed base plate 1 is fixedly connected to the transfer vehicle body 7 by bolts. In this embodiment, each of the four corners of the fixed base plate 1 is connected and fastened to the transfer vehicle body 7 by a bolt. The fixed base plate 1 and the first connecting block 11 are vertically fixed. The first connecting block 11 is fixedly connected to the third connecting block 13 through the second connecting block 12. The second connecting block 12 and the third connecting block 13 form a convex positioning end face. In this embodiment, the second connecting block 12 and the third connecting block 13 are vertically fixed. Of course, the included angle between the second connecting block 12 and the third connecting block 13 can be an obtuse angle, and the included angle between the second connecting block 12 and the first connecting block 11 can also be an obtuse angle. In this embodiment, 135° is taken as an example.

[0027] See Figure 2 A switch sleeve 3 is fixedly connected to the end of the positioning end face away from the hook 5, and a support block 2 is fixedly connected to the end of the positioning end face facing the hook 5. The support block 2 is made of nylon, and a positioning groove 21 is formed on the support block 2. The shape of the support block 2 matches the shape of the positioning end face. In this embodiment, it is L-shaped. The support block 2 includes a vertically fixed first connecting section and a second connecting section. The first connecting section is fixed to the third connecting block 13, and the second connecting section is fixed to the second connecting block 12. Positioning grooves 21 are formed on both the first connecting section and the second connecting section. The groove 21 can be rectangular or other shapes. The inductive switch 31 is located inside the switch sleeve 3, and its sensing end can pass through the positioning end face and extend into the positioning groove 21. The switch sleeve 3 also has a hole for observing the status of the inductive switch. The second connecting block 12 and the third connecting block 13 and the support block 2 are all provided with openings that allow their sensing ends to pass through, thereby realizing the detection of the hook 5 being hooked into the positioning groove 21. One end of the hook 5 has a round hole 51, and the hanging chain 6 is fixedly connected to the hook 5 through the round hole 51.

[0028] See Figure 2 A reinforcing rib 4 is also provided between the fixed base plate 1 and the first connecting block 11. In this embodiment, the reinforcing rib 4 is triangular and is located at the connection between the fixed base plate 1 and the first connecting block 11. One end of the reinforcing rib 4 is fixedly connected to the fixed base plate 1, and the other end is fixedly connected to the first connecting block 11. The shape of the hook 5 is adapted to the shape of the positioning groove 21. Both ends of the hook 5 and the first connecting section are snap-fitted. The free end of the hook 5 is bent toward the end of the first connecting section away from the second connecting section to achieve snap-fitting.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
