Automatic Dovetail Tenon Machine Solution

Industry introduction

The tenon-and-mortise structure is the main structural method of ancient Chinese buildings, furniture, and other wooden appliances.
It is mainly used for the right-angle connection of flat wood. The trapezoidal tenon can make the corners of the work piece join with high strength and avoid detachment under stress. Because of its good mechanical properties, dovetail tenon is very common in wooden furniture, and it is mostly used in drawers, wardrobes, etc.

Wooden furniture

As people's demand for solid wood furniture increases, the traditional dovetail tenon manufacturing process has been difficult to meet the huge market demand. In recent years, semi-automatic dovetail equipment and even fully automatic dovetail equipment have appeared on the market, greatly improving the production efficiency of solid wood furniture. The dovetail equipment system solution independently developed by VEICHI has been recognized by a large number of customers in the solid wood machinery industry for its advantages of high efficiency, high precision, and high stability.

System topology

Fully automatic dovetail equipment control system adopts VEICHI V5 motion controller + VI20 series touch screen + SD700 series high-performance servo + AC310 series inverter. The controller realizes the motion trajectory planning in the dovetail tenon processing process through the high-precision interpolation algorithm, which ensures the accuracy and efficiency of the processing.
