Description

TECHNICAL FIELD

[0001] The application relates to the technical field of material receiving equipment, in particular to an automatic lifting material receiving device for X-ray drilling of printed circuit boards. BACKGROUND

[0002] In the PCB manufacturing industry, X-ray drilling machines are usually equipped with mechanical conveying devices to complete the discharging operation of the board, and such systems usually rely on fixed-height material table tools. The X-ray post material receiving table used in the factory is a fixed material receiving table, and the height cannot be adjusted. When the material receiving table is full, the operator needs to manually adjust and intervene the material receiving position, and needs to pay attention to the actual height of the production board at all times. If the material receiving table is not replaced in time when the board is stacked too high, or the falling height of the board is too high, the board will be scratched, which seriously affects the quality of the PCB product and greatly reduces the efficiency of the operator. Therefore, designing an automatic lifting material receiving device for X-ray drilling of printed circuit boards has become a technical problem to be solved in the industry.

Poor flexibility: The fixed-height material receiving table cannot be adjusted according to different production needs or the working habits of operators, limiting its adaptability to different types of PCBs or different sizes of materials, resulting in frequent difficulties in receiving pieces or tedious operations.

[0006] 3. Low work efficiency: Due to the lack of lifting function or unreasonable design, the operator often needs to manually adjust and carry the PCB board, increasing the opportunity for manual intervention, which may cause fatigue or inaccurate operation over a long period of time, reducing production efficiency and reliability.

[0007] 4. Poor stability: After a long time of work, the receiving piece may deviate, the positioning of the discharging position may not be accurate, and the height difference between the PCB board discharging and the material table may cause the board to fall and slide, affecting the overall receiving piece precision and stability.
