The tracked AGV trolley platform sends the mold to the front of the corresponding shelf according to the preset path. The reducer motor drives the ball screw to rotate at a constant speed. The ball screw and ball nut cooperate to drive the slider to move vertically, thereby adjusting the height of the loading and unloading platform to be level with the height of the corresponding shelf. The servo motor drives the rotating roller to rotate at a constant speed through the reducer. The rotating rollers are connected and transmitted through toothed ring and chain.

[0017] (2) By setting up an RFID reading module, a first laser ranging sensor and a reflector, each layer of the shelf is affixed with a corresponding RFID tag at the front end during use. As the loading and unloading platform is raised or lowered, the RFID reading module reads the corresponding tag by radio frequency to determine the layer height, and the first laser ranging sensor determines the physical height by measuring the distance between it and the reflector. The two are combined to determine the actual lifting height. At the same time, the four sets of first laser ranging sensors and reflectors can also simultaneously measure the levelness of the loading and unloading platform, realizing the function of conveniently measuring the lifting height.

[0018] (3) By setting up a rear guardrail, a second laser ranging sensor and an audible and visual alarm, when in use, as the servo motor drives the rotating roller to rotate at a constant speed, the position of the mold on the loading and unloading platform can be adjusted. The rear guardrail can prevent the mold from sliding out from the rear. At the same time, the second laser ranging sensor senses the position of the mold in real time, providing a reference for the operation of the servo motor. When the distance exceeds the preset threshold and the mold is not in the unloading state, the servo motor drives the rotating roller to reverse and pull the mold towards the rear guardrail to prevent it from falling out. The audible and visual alarm will sound an alarm at the same time to remind the staff to pay attention, thus realizing the function of facilitating the calculation of the mold position.

[0033] Working principle: When using this utility model, firstly, the mold is placed horizontally on the loading and unloading platform 3. The tracked AGV platform 1 delivers the mold to the front of the corresponding shelf according to the preset path. The reduction motor 16 drives the ball screw 15 to rotate at a constant speed. The ball screw 15 and the ball nut 12 cooperate to drive the slider 11 to move vertically, thereby adjusting the height of the loading and unloading platform 3 so that it is level with the height of the corresponding shelf. The servo motor 10 drives the rotating roller 5 to rotate at a constant speed through the reducer 9. The rotating rollers 5 are connected and transmitted through the toothed ring 7 and the chain 8. The anti-slip rubber sleeve 6 on the outside of the rotating roller 5 increases the friction and drives the mold to move to the corresponding shelf. The shelf plate has its own rollers to facilitate the entry and exit of the mold. Each shelf has a corresponding RFID tag attached to its front end. As the loading / unloading platform 3 rises or falls, the RFID reading module 17 uses radio frequency to read the corresponding tag to determine the shelf height. The first laser range sensor 18 measures the distance between itself and the reflector 19 to determine the physical height. The combination of these two measures determines the actual lifting height. At the same time, the four sets of first laser range sensors 18 and reflectors 19 can also simultaneously calculate the levelness of the loading / unloading platform 3. As the servo motor 10 drives the roller 5 to rotate at a constant speed, the position of the mold on the loading / unloading platform 3 can be adjusted. The rear guardrail 20 can prevent the mold from sliding out from the rear. At the same time, the second laser range sensor 21 senses the position of the mold in real time, providing a reference for the operation of the servo motor 10. If the distance exceeds the preset threshold and the machine is not in the unloading state, the servo motor 10 drives the roller 5 to reverse and pull the mold towards the rear guardrail 20 to prevent it from falling out. The audible and visual alarm 22 simultaneously sounds an alarm to remind the staff.
