Description

Technical Field

[0001] The utility model relates to the field technology of PCB board transfer machines, in particular to a PCB board transfer machine with automatic width adjustment. Background Art

[0002] With the continuous development of society, more and more mechanical equipment has been manufactured and widely used in agriculture, industry, and the service industry. There are many types of mechanical equipment, and they have been further innovated to meet people's diverse needs. They play an indispensable role in people's work and life, and mechanical equipment is everywhere. The internal structure of mechanical equipment is becoming increasingly complex, and its functions are becoming more and more diverse, and are constantly being improved. Mechanical equipment generally includes a drive device, a speed change device, a transmission device, a working device, a braking device, a protective device, a lubrication device, a cooling device, etc., and different devices play different roles in mechanical equipment.

[0003] An SMT production line primarily consists of three processes: screen printing, component placement, and reflow soldering. The equipment used includes printers, placement machines, and reflow ovens. The placement machine is essentially a sophisticated industrial robot, a combination of mechanical, electrical, optical, and computer-controlled technologies. Through its suction, displacement, positioning, and placement functions, it quickly and accurately places electronic components onto designated pads on PCBs without damaging them or the PCB.

[0004] Before SMT placement, a PCB board transfer machine is required to transport the PCB board to the SMT processing equipment. Current PCB board transfer machines generally require manual adjustment of the board width to accommodate PCB boards of varying widths. This operation method is complex and cumbersome, and is time-consuming and labor-intensive when switching lines (adjusting the board width when switching production models), resulting in low production efficiency and high production costs. Manual operation is also difficult to adjust the board width, and the board width can easily be too large or too small. If the board width is adjusted too small, the PCB board will be difficult to fit into the transfer machine. If the board width is adjusted too large, the PCB board will easily fall off the transfer machine and be damaged. This compromises the quality of the PCB board, causing inconvenience in production and failing to meet existing needs. Therefore, it is necessary to develop a new technical solution to improve the current PCB board transfer machine. Utility Model Content
