Description

TECHNICAL FIELD

[0001] The present application relates to the field of automation production, in particular to a double-tray circulating feeding and storing device and a double-tray circulating feeding and storing process for automatic feeding and material assembly processing of an automatic production line. BACKGROUND

[0002] Automation refers to the replacement of manual work by machines to complete various production and processing. In the field of automation equipment, since a product is generally composed of multiple scattered parts, various parts need to be automatically assembled by equipment in the actual production process to form a complete product structure. Therefore, automatic assembly processing of various materials is widely used in many fields, such as various intelligent terminal devices, mobile phones, tablet computers, smart watches, batteries, power supplies, and various daily products and toys, all of which have production needs for automatic assembly of materials. Since the types and specifications of materials in the automatic assembly process are different, existing automatic assembly technologies generally use separate assembly equipment for different materials, making it difficult to form standardized and universal assembly equipment.

[0003] For automatic assembly of materials, different materials need to be assembled, so the assembled materials such as various electronic components and base materials such as PCB boards are involved. Therefore, the automatic assembly process of materials as a whole includes three process sections, namely, automatic feeding process of assembled materials, feeding process of base materials, and automatic assembly process of assembled materials and base materials.

[0004] For the feeding process of assembled materials, existing automatic feeding processes include vibration disc feeding, material belt feeding, Tray disc feeding, etc. Different feeding methods are selected according to different specifications of materials. Tray disc, also known as material disc, is a mechanism for loading materials. In the process of assembly, processing, and detection, the material disc is used to carry assembled materials. Generally, a single material disc can carry multiple materials, and to ensure continuous feeding, multiple material discs are stacked together for overall feeding. Traditional material disc feeding technology is mostly manual, which involves carrying the material disc loaded with materials to the material taking station, taking the materials from the material taking station after the materials are taken, and placing a new full material disc. This material disc feeding method has low production efficiency and cannot meet the production capacity needs of modern automatic production lines. Therefore, to improve the efficiency of material disc feeding, technical problems need to be solved, including automatic feeding of multiple stacked material discs, taking of material discs, taking of materials, and recycling of empty material disc storage and feeding.

[0005] In addition, the traditional tray feeding generally adopts a single channel mode, i.e. only one stack of trays can be fed at a time. In actual production process, there is a situation of double-line or multi-line synchronous assembly. The single channel feeding mode of the tray cannot meet the above requirements. Therefore, it is necessary to design a double channel or multi-channel tray feeding device from the aspects of structure and process. In addition, when the tray is fed to the assembly robot for taking the material, the traditional feeding mode adopts a single channel straight line feeding mode, i.e. the tray is moved to the taking position, and after the assembly robot takes the material on the tray at the taking position, the empty tray is moved away, and then the tray full of material is moved to the taking position for taking and assembling. The above mode can only move the full tray after the empty tray is moved away. When the empty tray is moved away and the full tray is moved, the assembly robot is in a stop state. The assembly can only be performed again after the empty tray is taken away and the full tray is moved to the position. The assembly efficiency is affected. SUMMARY

This kind of staggered feeding mode realizes the assembly of the assembly robot without stopping, reduces the standby time, and can effectively improve the assembly efficiency.
