Description

Technical Field

[0001] The utility model relates to the technical field of PCB mounting, in particular to a PCB surface mounting device. Background Art

[0002] PCB board, also known as printed circuit board or printed circuit in Chinese, is an important electronic component. It is the support body of electronic components and the provider of electrical connections for electronic components. Because it is printed using electronic printing technology, it is called a "printed" circuit board. When mounting PCB boards, printed solder paste needs to be soldered to the surface of the PCB board for easy use later.

[0003] For example, a PCB patch welding device (Announcement No.: CN219684253U) includes a welding table, the upper surface of the welding table is provided with four mounting holes in a rectangular array, and the upper surface of the welding table is welded with four stable support plates in a rectangular array. In the above scheme, the welding device is provided with a stable support plate, a mounting rod, a connecting plate, a mounting plate and a telescopic assembly. When welding is required at different positions of the PCB board to be welded, it is only necessary to start the electric hydraulic rod inside the telescopic assembly. Then the electric hydraulic rod will drive the connecting plate to move on the surface of the mounting rod through the mounting ring until the laser welding head is moved to the position required for the work. Because the laser welding head is connected to the connecting plate through the mounting plate, the movement of the connecting plate can drive the movement of the laser welding head. Because the electric hydraulic rod has the function of automatic telescopic movement, it can save the time required for welding, thereby improving the welding efficiency of the device.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when using the above equipment, manual pushing of the positioning plates in the two sets of positioning devices is required, and the positioning plates are driven by the telescopic rod and the return spring to press and fix the PCB board. Manual operation requires time and effort to accurately control the movement and pressing force of the positioning plates. Especially in a large-scale production environment, this manual operation will greatly reduce production efficiency and increase labor costs. In addition, during the operation, workers need to directly contact the mechanical equipment and the PCB board. If the operation is improper or the equipment fails, safety accidents such as pinching and scratching are likely to occur. Therefore, we need to propose a PCB surface mounting device.
