Description

Technical Field

[0002] During the transfer of PCB board loading and unloading, it is generally carried out by manually transporting it to the pick-and-place vehicle, pulling it to the production area, and then manually unloading it. Moreover, PCB boards of different sizes are placed and conveyed for production of different-sized PCBs. When using the pick-and-place device for PCB board loading and unloading, the manual handling method is likely to cause muscle strain to the staff over a long time, and there are handling risks during work. Especially, larger PCB boards are heavier during loading and unloading, and multiple staff members are required to cooperate in handling and conveying, which affects production efficiency.

[0003] In order to overcome the above-mentioned defects, the prior art (application number CN202322969355.9, Chinese patent application with application date 2023-11-03) is an automatic loading and unloading device for PCB boards, which has a simple structure, is easy to manufacture and has low cost. The combined structure of the lifting cylinder, the horizontal mounting bracket and the material cage has clear layers, a simple structure and is easy to manufacture. It is easy to implement when applied to specific PCB loading and unloading scenarios, which can greatly reduce the manufacturing cost and is convenient for loading and unloading. There is also the prior art (application number CN202010547377.4, Chinese patent application with application date 2020-06-16) an automatic loading and unloading system for the tin spraying process of PCB boards. When producing PCB boards of different sizes, the three devices of the positioning device, the adjustable fixture of the mechanical arm and the adjustable slide of the tin spraying machine in the automatic loading and unloading system do not require the operator to manually adjust each device. Only the new PCB board size parameters need to be input into the system, and the system can automatically adjust the three devices into place, which saves time and effort, can quickly cope with PCB boards of various sizes, and improves production efficiency. The adjustable fixture of the mechanical arm It has a large stroke adjustment function, drives the cylinder to move through the screw slide, and then drives the clamp to clamp the PCB board through the cylinder, which can ensure that the PCB board is accurately and quickly grabbed in the board-taking device; and the prior art (application number CN202122737588.7, Chinese patent application date 2021-11-10) a rack-type loading and unloading device for PCB, when loading, the clamping device clamps the PCB board from the rack board frame and places the PCB on the conveying table; when unloading, the clamping device clamps the PCB board from the conveying table and places the PCB board on the rack board frame, and uses a clamping device with a high degree of automation instead of manual labor, which can meet the loading rate or the unloading rate consistent with the rolling speed of the roller, avoiding manual labor from not having time to pick up the PCB board, thereby causing the PCB board to be damaged on the conveying table; although the prior art can complete the loading and unloading of PCB boards, it is inconvenient to load and unload PCB boards of different sizes during work, and the conveying size is relatively single, which affects the production effect, and it is difficult to store and use a single PCB board.
