The magnetic levitation guide rail component drives the vehicle body to move, passing through the glass feeding mechanism, interior feeding mechanism and under-car feeding mechanism in sequence. Each time it reaches the carrier in front of the feeding structure, it stops. The loading robot module picks up the corresponding material and places it on the vehicle body.

The loading robot module, together with the detection camera, identifies and positions the corresponding material, making the picking accurate and efficient, with a high degree of automation.

[0019] The wheel feeding assembly uses a vibrating feeding device to feed wheels. The vibrating wheels then flow into intermittent feeding devices. Two staggered intermittent feeding devices, together with a variable-pitch picking assembly, grab the wheels and assemble them onto the bottom of the car. A flipping and riveting assembly then assembles the bottom of the car onto the body and fixes it. A riveting module rivets the front and rear positions of the bottom of the car. Finally, the wheels flow back to the body feeding module via a magnetic levitation guide rail assembly. After the body flipping assembly flips the completed car body, the feeding robot module picks it up again and puts it back on the carrier plate to complete the unloading. The entire process requires no staff assistance, resulting in high toy car assembly efficiency and significantly reduced labor costs. Attached Figure Description

After the vehicle body is placed on the body flipping component 13 and flipped, the loading robot module 4 picks it up again and places it on the carrier 125 of the magnetic levitation guide rail component 12. The magnetic levitation guide rail component 12 drives the vehicle body to move, passing through the glass feeding mechanism 31, the interior feeding mechanism 32 and the bottom feeding mechanism 33 in sequence. Each time it reaches the front carrier 125 of the feeding structure, it stops. The loading robot module 4 picks up the corresponding material, puts it in and installs it on the vehicle body. The process of putting the material into the vehicle body does not require manual operation. The loading robot module 4, together with the detection camera 43, identifies and locates the corresponding material and puts it into the carrier 125.

[0076] The wheel feeding assembly 34's feeding vibration device 342 feeds the wheels, and the vibrating wheels flow out into the intermittent feeding device 343. The two staggered intermittent feeding devices 343, together with the variable pitch picking assembly 51, grab the wheels and assemble them onto the bottom of the vehicle. The flipping riveting assembly 52 assembles the bottom of the vehicle onto the vehicle body and fixes it. The riveting module 6 rivets the front and rear positions of the bottom of the vehicle. Finally, the wheels flow back to the side of the vehicle body feeding module 2 through the magnetic levitation guide rail assembly 12. The laser marking device 8 laser prints the date on the bottom of the vehicle. After the vehicle body flipping assembly 13 flips the completed vehicle body, the feeding robot module 4 picks it up again and puts it back on the carrier plate to complete the unloading.

[0077] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
