2、 Basic Composition

This device is equipped with a touch screen,PLCControl, servo motor,It consists of a framework, mechanical transmission part, and electrical automatic control part.

framework

The equipment framework is assembled using industrial aluminum materials, and this structure is a combination of heavy-duty structures with high stress, high strength, and high support requirements. The shape of the profile adopts rounded transition, and the surface is treated with anodized silver white, which is elegant, beautiful and corrosion-resistant.

The frame is divided into two boxes, left and right. The right box is a fixed box, and the left box can be freely adjusted according to the size of the refrigerator being tested. The maximum width that can be adjusted between the left and right boxes is2000mmThe swing arms installed on the vertical shafts on the left and right sides of the box are used for opening the doors of the vertical refrigerator/Close the test; The swing arm installed on the horizontal axis in the middle of the two boxes is used for opening the horizontal refrigerator door/Close the test.

2Mechanical transmission mechanism

The equipment adopts a single transmission shaft driven by a motor, and up to three mechanical arms are installed on the left and right vertical shafts respectively to achieve the opening of multiple doors/Closing action, the three robotic arms can adjust their up and down positions according to the height of different refrigerator doors, and the three robotic arms can rotate simultaneously.

The rotation of the robotic arm is achieved by the motor driving the eccentric wheel and connecting rod to produce reciprocating motion, causing the vertical shaft to rotate within a fixed angle. The rotation angle can be set to45°and60°Two levels. Opening the door of a horizontal refrigerator/Guan is achieved through the meshing transmission of bevel gears on the vertical and horizontal axes, thereby transforming vertical rotational motion into horizontal rotational motion.

3Electrical control part

The equipment adopts advanced technologyPLCThe automatic control mode combining program controller, human-machine interface, and variable frequency speed control system is achieved through two methods750WThe deceleration motor serves as the main driving force and is driven by a variable frequency speed regulation system to achieve door opening/Close the speed10turn/divide---32turn/The purpose of infinitely adjustable partitioning; At the same time, the control system performs logical control and full process monitoring of the testing process, and responds to the current testing status through intuitive windows, including timely alarm and automatic shutdown of faults, making the testing work easier and smoother to operate, truly achieving the goal of unmanned operation.
