Description

Lifting mechanism applied to storage mobile carrier structure

The present invention relates to a main operation mode that can reliably achieve the rotation of the frame directly driving the material rack to turn or the frame does not move, but only the lifting mechanism drives the tray to perform angle rotation adjustments, etc., especially refers to a lifting mechanism to move items The structure of the storage mobile vehicle to the designated location.

According to, generally the products processed in a high-precision way are high-precision products or communication products, which are required to avoid collisions during manufacturing, assembly, testing or shipping and transportation, so most of them use robotic arms or conveying equipment To ensure the quality and yield of products; in addition, the history of human development has always been closely related to logistics. Information technology e-generation business behavior and international operations, especially online e-commerce, TV channel shopping or human life are all related to Logistics behavior has an inseparable relationship. The logistics industry also introduces e-logistics management systems and electronic communication systems to in-depth management of warehousing and transportation behaviors; logistics centers usually act as bridges between manufacturers and retailers. When supply trucks arrive In the logistics center, it is necessary to go through the "restock" operation to confirm that the items are put into the warehouse, and then the items are "stocked in" for storage in order to ensure that the inventory items are well kept.

When the logistics center receives the customer's order, the staff must first separate the vertically stacked logistics boxes one by one to facilitate the picking of the goods of different orders into each logistics box. At this time, the required item information must be pasted To the logistics box, when it is conveyed to the operator of the next workstation through the conveyor belt, the sensor will automatically detect the item information contained, and the picker will then follow the instructions to pick the goods; however, these use manpower for stacking The separation operation is very laborious and time-consuming. In addition, the logistics center needs to set up more than one conveyor belt to place and transport several disassembled and separated logistics boxes to facilitate the transportation of stacked and separated logistics boxes. If there is no conveyor belt that can transport goods, it must rely on manual handling. It can be seen that it takes a lot of manpower and time to prepare logistics boxes for picking in advance.
