Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electronic automation, and particularly relates to a PCBA feeding machine capable of adjusting positions. BACKGROUND

[0002] A printed circuit board (PCBA) is an important electronic component, is a support body of electronic elements, and is a provider of electronic element circuit connection. In electronic device manufacturing, a PCBA feeding machine is needed to feed and convey PCBA boards. A PCBA feeding machine with secondary positioning function and a feeding method thereof are disclosed in a patent with the application publication number CN117800071A. The PCBA feeding machine body is provided with a carrier cover plate conveying device, a product carrier unit, a product positioning and placing unit, and a control system. The control system can be connected to MES to realize information intercommunication and process control. The product positioning and placing unit has a secondary positioning function. The feeding method includes five steps through secondary positioning of the product. The product can be more stable and safe during movement to the carrier. This positioning method can reduce shaking and collision of the product during transportation, thereby reducing the risk of damage. A PCBA feeding machine is disclosed in a patent with the authorization publication number CN217755713U. The PCBA feeding machine includes a rack, at least one tray containing device for containing a tray full of PCBA, at least one empty tray containing device for containing an empty tray, a turnover assembly for turning the PCBA in the tray containing device towards the turnover assembly, a material transfer assembly for transferring the PCBA in the tray containing device to the turnover assembly or transferring the empty tray in the tray containing device to the empty tray containing device, and a material unloading assembly for transferring the PCBA turned over by the turnover assembly to the external conveying equipment. The tray containing device and the empty tray containing device are both slidingly connected to the rack. The turnover assembly is installed on one side of the tray containing device. The material transfer assembly is arranged beside the tray containing device. The material transfer assembly can realize automatic transfer of the material in the tray containing device, thereby making the entire PCBA feeding process automatic and improving the feeding efficiency of the PCBA. However, in combination with the actual working process of the PCBA feeding machine, the current PCBA feeding machine still has some disadvantages, such as: The feeding efficiency is slow, and the feeding cannot be continuously and quickly performed, which is not conducive to improving the conveying and processing efficiency. The position is fixed, the applicability of the PCBA feeding is poor, and the PCBA feeding cannot be adjusted and used, which has great limitations. The error is large because the PCBA feeder is used to feed stacked feed trays.
