Description

Technical Field

[0001] The utility model relates to the technical field of loading and unloading equipment, in particular to a double-station loading and unloading equipment for PCB substrates. Background Art

[0002] PCB board is one of the important components of the electronics industry. During the production and processing of PCB boards, each PCB board is transported by a PCB board conveying mechanism and goes through multiple processes on the conveying line to complete the production and processing of the PCB boards. The existing work of placing PCB boards on the PCB board conveying mechanism is done manually, with staff members picking up and placing them one by one. The repeated operation can easily make the staff tired, reducing the work efficiency of PCB board production and processing. Moreover, the long-term manual picking and placement also greatly increases the cost of PCB board production and processing. Patent No. CN202220938556.5 discloses a PCB board loading and unloading equipment, which includes an equipment frame, a PCB board conveying mechanism, a plate pushing loading mechanism, and a control system; the plate pushing loading mechanism includes a plate pushing loading frame, a first rack conveying mechanism, a PCB board pushing mechanism, a lifting mechanism, a second rack conveying mechanism, and a PCB board rack. This utility model utilizes a push-plate loading mechanism, a PCB board conveying mechanism, and a control system. Under the control of the control system, all PCB boards on a PCB board rack are automatically and sequentially moved onto the PCB board conveying mechanism, thereby replacing manual handling and placement. This improves the efficiency of PCB board production and processing and reduces the cost of PCB board production and processing. The previous loading and unloading equipment only functions to remove PCB boards from the rack one by one and can only be docked with the loading and unloading equipment, which has certain limitations. Therefore, the utility model provides a dual-station loading and unloading equipment for PCB substrates. Utility Model Content
