Description

TECHNICAL FIELD

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

[0002] Automation refers to replacing manual work with machines to complete various production and processing. In the field of automatic equipment, a product is generally composed of multiple scattered parts, and in the actual production process, various parts need to be automatically assembled by equipment to form a complete product structure. Therefore, automatic assembling of various materials is a common production process and is applied to 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 of automatic material assembling. Because the types and specifications of materials in the automatic assembling process are different, existing automatic assembling technologies generally use separate assembling equipment for different materials, which is difficult to form a standardized and universal assembling equipment.

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

[0004] For the feeding process of the assembled materials, existing automatic feeding processes include vibration disc feeding, material belt feeding, and Tray feeding, and different feeding methods are selected according to different specifications of the materials. The Tray, also known as a material tray, is a mechanism for loading materials. In the process of assembling, processing, and testing, the Tray is used to carry the assembled materials. Generally, a single Tray can carry multiple materials, and to ensure continuous feeding, multiple Trays are stacked together for overall feeding. Traditional Tray feeding technology is to manually carry the Tray loaded with materials to a material taking station, take the materials from the material taking station after the materials are taken, and then place a new full Tray. This Tray feeding method has low production efficiency and cannot meet the production capacity needs of modern automatic production lines. Therefore, to improve the Tray feeding efficiency, technical problems need to be solved, including automatic feeding of multiple stacked Trays, taking of the Trays, taking of the materials, and empty Tray circulating storing and feeding.
