Refrigerator door switch life testing machinebasic components

This device is equipped with a Siemens touch screen from Germany,PLC control, consisting of cylinders, frames, mechanical transmission parts, and electrical automatic control parts.

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 left and right boxes, and the distance between the two boxes can be freely adjusted according to the size of the refrigerator being tested. The maximum adjustable width between the left and right boxes is2200mm. The swing arms installed on the vertical shafts on the left and right sides of the box are used for testing the door opening/closing of the vertical refrigerator; The cylinder push rod installed on the horizontal axis in the middle of the two boxes is used for testing the opening/closing of the horizontal refrigerator door.

2. Mechanical transmission mechanism

The equipment adopts cylinder driven mode, 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

3. Electrical control part

The equipment adopts advanced technologyThe automatic control method combining PLC program controller, human-machine interface, and speed control system uses two cylinders as the main driving force, and the PLC program controller controls the test frequency to ensure that the number of test cycles is 20 to 25 per minute; 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.Vertical refrigerator (including left)/The installation and fixation of right side open door refrigerators and double door refrigerators can rely on the screw adjustment clamping device installed on the left and right boxes, and the combination of aluminum profile angle brackets and screw adjustment clamping device for fixation
