Description

TECHNICAL FIELD

[0001] The utility model relates to PCB substrate processing technical field, concretely relates to sand blasting effect online detection formula PCB substrate processing device. BACKGROUND

[0002] The substrate is the basic material for manufacturing PCB, and generally, the substrate is copper-clad laminate, and single or double-sided printed boards are manufactured by selectively processing holes, electroless copper plating, electroplating copper, etching and other processes on the substrate material - copper-clad laminate to obtain the required circuit pattern, which has the functions of conduction, insulation and support. In the surface treatment process of the current PCB substrate, sand blasting treatment is usually required, and the glossiness, flatness and uniformity of the substrate after sand blasting treatment need to be detected.

[0003] In the sand blasting treatment and online detection production process of the PCB substrate, there are many technical bottlenecks in the substrate conveying link. On the one hand, the existing conveying unit mostly adopts the traditional single conveyor belt structure, lacks effective substrate positioning and anti-deviation measures, and in the actual production process, due to the running jitter of the conveyor belt, the deviation of the substrate placement position and other factors, the substrate is prone to deviation during conveying. Once the substrate deviates, the edge of the substrate will rub or collide with the conveying structure on both sides of the conveyor belt, not only causing scratches, damage and other physical damage on the surface of the substrate, affecting the appearance quality of the substrate, but also damaging the circuit structure inside the substrate, causing the electrical performance to decline, ultimately causing the product to be scrapped and increasing the production cost.

[0004] On the other hand, the existing conveying device is difficult to adapt to the production needs of PCB substrates of different widths. For substrates of different specifications, it is difficult to quickly and conveniently position and guide them, and usually requires manual adjustment or replacement of specific auxiliary tools, which is tedious and inefficient, seriously restricting the flexible production capacity of the production line. In addition, the existing sand blasting effect online detection type PCB substrate processing device lacks automatic classification storage function after completing the detection of the substrate. The qualified and unqualified substrates are often mixed together or rely on manual sorting, which not only increases the labor cost, but also easily causes sorting errors, affecting the orderly progress of the subsequent production process, and is difficult to meet the requirements of modern intelligent manufacturing for efficient and accurate production. It is not convenient to position and guide workpieces of different widths, and it is not convenient to classify and store workpieces according to the detection results after the existing equipment detects the workpieces, affecting the convenience and practicality of the equipment in detecting workpieces.
