Wood-Plastic Fence Automated Production Line — No More Manual Screw Fastening

Shenzhen Honred Technology Co., Ltd. launched China's first automated wood-plastic composite (WPC) fence production line in 2016, and it was put into production at Sentai Co., Ltd.

Working Sequence

Station 1

1. The operator places the aluminium strip from the front.

2. Wood strips are placed one by one on the side loading machine. When loading is complete and start is pressed, the loading machine carries the boards into the main frame; the push plate cylinder then lowers and the loading machine base plate retracts, placing the wood boards onto the aluminium strip.

3. The wood strips are clamped and positioned.

4. The cylinder lifts the product and drilling and screw fastening begin along the programmed coordinates.

5. When all screws are fastened, another set of cylinders lifts the conveyor belt, releasing the semi-finished product from the fixture and transferring it to the next station.

6. The loading machine can accept the next boards after completing one working cycle.

Station 2

This station is the same as the original design. Its function is to receive the semi-finished fence flowing in from station 1, then use a servo motor to drive the upper and lower conveying mechanism to rotate the product by 180 degrees, and transfer the turned product to the next station.

Station 3

Station 3 is similar to station 1 with some differences.

1. After the turned product flows in, it is positioned by a stop cylinder and side clamping cylinders.

2. Wood strips are placed one by one on the side loading machine. When loading is complete and start is pressed, the loading machine carries the boards into the main frame; the push plate cylinder then lowers and the loading machine base plate retracts, placing the wood boards onto the aluminium strip.

3. The wood strips are clamped and positioned.

4. The cylinder lifts the product and drilling and screw fastening begin along the programmed coordinates.

5. When all screws are fastened, another set of cylinders lifts the conveyor belt, releasing the finished product from the fixture and transferring it to the next station.

Station 4

Station 4 is mainly for unloading. A six-axis unloading robot or a gantry-type manipulator can be added according to customer requirements, which can save one operator.
