Description

TECHNICAL FIELD

[0001] The utility model relates to a circuit board detection technical field, specifically a circuit board processing detection device. BACKGROUND

[0002] In the electronic manufacturing field, as the key basic component of electronic products, the quality of the circuit board directly affects the performance and stability of the entire electronic product. With the rapid development of electronic products towards miniaturization, multifunctionalization and high precision, the processing precision and quality detection requirements of the circuit board are increasingly stringent. The traditional circuit board detection method mostly relies on manual operation. The detection personnel hold simple tools and check the key indicators such as circuit connectivity, solder joint quality and component installation precision of the circuit board by naked eye and experience. This manual detection mode has many drawbacks. First, the detection efficiency is extremely low. In the face of large-scale circuit board production tasks, manual detection cannot meet the demand of rapid delivery, which seriously restricts the production progress. Second, the detection accuracy cannot be guaranteed. The resolving power of the human eye is limited, and visual fatigue is easy to occur after a long time of work, which is likely to miss hidden defects such as fine open circuit, virtual welding and slight component deviation on the circuit board, resulting in defective products flowing into the next production link and greatly increasing the subsequent rework cost and product rejection rate.

[0003] According to Chinese patent application No. CN220251561U, a circuit board processing detection device is provided. The device can fix and unlock the position of the circuit board conveniently, which is beneficial to improve the detection efficiency. The screw rod, handle and sliding seat can freely adjust the distance between the two sliding seats according to the size of the circuit board, which is convenient for fixing circuit boards of different sizes and improves the applicability of the detection device. The electric telescopic rod, screw rod and handle can adjust the position of the detection head conveniently without the need to re-adjust and fix the position of the circuit board, thereby improving the detection efficiency. However, the existing detection components are relatively mature. The detection components are usually fixed on the top due to installation problems and cannot be adjusted according to the height of the detection equipment and the detection requirements. This may cause the detection instrument to fail to accurately detect the circuit board. For example, the probe of the detection equipment cannot reach a specific position of the circuit board, or the viewing angle during detection is not good, which affects the observation and detection of certain areas on the circuit board. The circuit board may move or shake during the detection process, which may change the contact position between the detection instrument and the circuit board, affecting the accuracy and repeatability of the detection results and may cause misjudgment or omission. Therefore, a circuit board processing detection device is proposed to solve the above problems. SUMMARY
