Description

TECHNICAL FIELD

[0001] The utility model relates to PCB production and processing equipment technical field especially relates to a full -automatic backflow type's PCB packing machine of pallet. BACKGROUND

[0002] In the PCB (printed circuit board) production process, packaging is an important link to ensure that the product is not damaged during transportation and storage. With the rapid development of electronic manufacturing industry, the production and precision requirements of PCB are continuously improved, and the traditional packaging method has gradually failed to meet the needs of modern production.

[0003] The traditional PCB packaging method mainly relies on manual operation or semi-automatic equipment. With the progress of technology, the purely manual packaging method has been gradually replaced by semi-automatic equipment. However, the existing semi-automatic packaging equipment still has significant problems: although the main process of packaging (such as heat sealing, cutting, etc.) has been completed by the equipment, the feeding and discharging of PCB is still mainly manual. Specifically, the existing technology usually uses a pallet for feeding and discharging, and sets an upper feeding station, a packaging station and a lower discharging station. The operator first places the bottom film on the pallet, then places the PCB board on the pallet, and moves it to the upper feeding station, and then the upper feeding station automatically transports the pallet to the packaging station for packaging. However, this design has a obvious defect: the upper feeding station and the lower discharging station are usually set on both sides of the packaging station, and the pallet after completing the discharging needs to be manually recycled and moved to the upper feeding station for the next packaging operation. This feeding and discharging method has the following problems: (1) manual movement of the pallet is not only slow, but also easy to cause interruption of the production process, affecting the overall production efficiency; (2) the operator needs to frequently move the pallet between the upper and lower feeding stations, increasing the work intensity, and also easy to cause damage to the PCB or the pallet due to operation errors.
